Abstract
Objective: To explore the clinical characteristics, pathological features, and diagnosis and treatment strategies of nasal chondromesenchymal hamartoma (NCMH) in infants and young children. Methods: A retrospective analysis was conducted on seven cases of NCMH infants and young children admitted to Beijing Children's Hospital, Capital Medical University from April 2015 to January 2022. The cohort included 5 males and 2 females, aged from 6 days to 2 years and 3 months. General information, clinical symptoms, imaging findings, treatment plans, postoperative complications, recurrence and follow-up time were collected, summarized and analyzed. Additionally, immunohistochemical characteristics of the lesion were examined. Results: The clinical symptoms of 7 children included nasal congestion, runny nose, open mouth breathing, snoring during sleep, difficulty feeding, and strabismus. All patients underwent electronic nasopharyngoscopy examination, with 5 cases of tumors located in the right nasal cavity and 2 cases in the left nasal cavity. No case of bilateral nasal cavity disease was found. All 7 patients underwent complete imaging examinations, with 5 patients underwent MRI and CT examinations, 1 patient underwent CT examination only, and 1 patient underwent MRI examination only. The CT results showed that all tumors were broad-based, with uneven density, multiple calcifications and bone remodeling, and some exhibited multiple cystic components. The MRI results showed that the tumor showed low signal on T1 weighted imaging and high or slightly high signal on T2 weighted imaging. All patients were diagnosed through histopathological examination and immunohistochemistry, including 7 cases of Ki-67 and SMA (+), 5 cases of S-100 and Vimentin (+), and all EMA and GFAP were negative. All patients underwent endoscopic resection surgery through the nasal approach, with 3 cases using navigation technology. Five cases of tumors were completely removed, and two cases of tumors were mostly removed. No nasal packing was performed after surgery, and no postoperative nasal, ocular, or intracranial complication occurred in all patients. Follow up assessments conducted 6 to 84 months post-surgery revealed no instances of tumor recurrence in any of the patients. Conclusions: The clinical symptoms of children with NCHM mainly depend on the size and location of the tumor. Nasal endoscopic surgery is the main treatment method. In cases where critical structures like the skull base or orbit are implicated, staged surgical interventions may be warranted. Long-term follow-up is strongly advised to monitor for any potential recurrence or complications.

Abstract
AIM To report the authors' experience of bronchial artery embolisation (BAE) in a series of patients to control haemoptysis associated with infected pulmonary artery pseudoaneurysms (PAPs). MATERIALS AND METHODS All patients who underwent BAE based on computed tomography angiography (CTA) findings indicative of haemoptysis between February 2019 and September 2022 at Xiangyang Central Hospital were identified. Charts of patients with haemoptysis and infectious PAPs were reviewed retrospectively. Data were collected data on age, sex, underlying pathology, source pulmonary artery of the PAP, association with cavitary lesions or consolidation, systemic angiography findings, technical and clinical success, and follow-up. RESULTS Seventeen PAPs were treated in 16 patients, with a mean age of 60.3 years (range: 37-82 years). The most common underlying cause was tuberculosis (15/16, 93.8%). Imaging by CTA did not identify the source pulmonary artery for 15 (88.2%) PAPs; all were associated with cavitary lesions or consolidation. All PAPs were visualised on systemic angiography. The technical and clinical success rates were both 87.5%. Two patients who experienced a recurrence of haemoptysis during follow-up underwent repeat CTA, which confirmed the elimination of the previous PAP. CONCLUSION BAE may be a valuable technique to control haemoptysis associated with infectious PAPs that are visualised on systemic angiography. A possible contributing factor is PAPs arising from very small pulmonary arteries.

Abstract
Objective: To investigate the main mechanisms of pulmonary fibrosis following silica nanoparticles (SiNPs) exposure through constructing the macrophage-fibroblast model in vitro, which simulated the process of pulmonary fibrosis. Methods: In January 2021, human mononuclear leukemia cells (THP-1) were treated with 0, 25, 50, 100 μg/ml SiNPs for 24 h. The supernatant of THP-1 cells was collected and applied to human embryonic lung fibroblast cells (MRC-5) which divided into control and low, medium and high dose groups at the logarithmic growth stage for 24 h. MRC-5 cell viability was detected by CCK8. The hydroxyproline (Hyp), interleukin 6 (IL-6), interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) expression were detected in the supernatants of MRC-5. The changed proteins were detected by liquid-phase mass spectrometry in high dose group. GeneCard database were applied to identity the differential pulmonary fibrosis proteins in high dose group. Gene Ontology (GO) was performed to identity the key biological process in differential pulmonary fibrosis proteins of high dose group. The String database was used to construct the protein-protein interactions (PPI) network of differential pulmonary fibrosis proteins. The APP of CytoHubba was applied to calculate the key protein of differential pulmonary fibrosis proteins in PPI network. Correlation coefficients between key differential pulmonary fibrosis proteins were calculated using Pearson correlation analysis. Western blotting was applied to detect the expression of key proteins of differential pulmonary fibrosis proteins in different groups. Results: CCK8 results showed that MRC-5 cell viability was increasing in low, medium and high dose groups compared with control group (P<0.05). The expression levels of Hyp and IL-1β in different group were increased compared with control group, the expression levels of IL-6 and TNF-α were increased in high dose group compared with control group (P<0.05). GeneCard database identified 26 differential pulmonary fibrosis proteins, which were mainly involved in extracellular matrix hydrolysis, cell inflammatory response, tissue repair, cell proliferation, inflammation response by GO analysis. The APP of CytoHubba was calculated that matrix metalloproteinase 9 (MMP9) and tissue inhibitor metalloproteinase 1 (TIMP1) played an important role in PPI network. The results of correlation analysis showed that MMP9 was correlated with the expression of matrix metalloproteinase 1 (MMP1), matrix metalloproteinase 3 (MMP3), TIMP1 and epidermal growth factor receptor (EGFR) (r=0.97, 0.98, 0.94, 0.93, P<0.05). Western blotting results showed that TIMP1 protein expression was increased in low, medium and high dose groups, while MMP9 protein expression was increased only in high dose group (P<0.05) . Conclusion: Differential expression proteins related with pulmonary fibrosis in MRC-5 cells mainly regulate biological processes of extracellular matrix hydrolysis, tissue repair, and cellular inflammation response following SiNPs exposure. MMP9 and TIMP1 may be the key proteins, which affected the fibrosis process in vitro pulmonary fibrosis model.

Abstract
The coronary artery as a responsible vessel for hemoptysis is very rare. This patient was admitted to the hospital with bronchiectasis and hemoptysis, and the right coronary artery was found to be one of the non-bronchial systemic arteries by computed tomography angiography, and the hemoptysis stopped immediately after successful embolization of all bronchial arteries and non-bronchial systemic arteries by bronchial artery embolization. However, the patient had a recurrence of a small amount of hemoptysis 1 month and 3 months after surgery. The patient underwent lobectomy of the lesion after multidisciplinary discussion and did not have any hemoptysis after surgery.

Abstract
Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.

Abstract
BACKGROUND The World Health Organization has reported that the treatment success rate of multi-drug resistance tuberculosis is approximately 57% globally. Although new drugs such as bedaquiline and linezolid is likely improve the treatment outcome, there are other factors associated with unsuccessful treatment outcome. The factors associated with unsuccessful treatment outcomes have been widely examined, but only a few studies have developed prediction models. We aimed to develop and validate a simple clinical prediction model for unsuccessful treatment outcomes in patients with multi-drug resistance pulmonary tuberculosis (MDR-PTB). METHODS This retrospective cohort study was performed between January 2017 and December 2019 at a special hospital in Xi'an, China. A total of 446 patients with MDR-PTB were included. Least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression were used to select prognostic factors for unsuccessful treatment outcomes. A nomogram was built based on four prognostic factors. Internal validation and leave-one-out cross-validation was used to assess the model. RESULTS Of the 446 patients with MDR-PTB, 32.9% (147/446) cases had unsuccessful treatment outcomes, and 67.1% had successful outcomes. After LASSO regression and multivariate logistic analyses, no health education, advanced age, being male, and larger extent lung involvement were identified as prognostic factors. These four prognostic factors were used to build the prediction nomograms. The area under the curve of the model was 0.757 (95%CI 0.711 to 0.804), and the concordance index (C-index) was 0.75. For the bootstrap sampling validation, the corrected C-index was 0.747. In the leave-one-out cross-validation, the C-index was 0.765. The slope of the calibration curve was 0.968, which was approximately 1.0. This indicated that the model was accurate in predicting unsuccessful treatment outcomes. CONCLUSIONS We built a predictive model and established a nomogram for unsuccessful treatment outcomes of multi-drug resistance pulmonary tuberculosis based on baseline characteristics. This predictive model showed good performance and could be used as a tool by clinicians to predict who among their patients will have an unsuccessful treatment outcome.

Abstract
Objective: To evaluate the clinical efficacy of bleomycin lavage combined with N-butyl-2-cyanoacrylate glue embolization and resection in the treatment of orbital vascular malformations. Methods: It was a retrospective case series study. Patients with orbital vascular malformations diagnosed at the Ophthalmology Division of Chinese PLA General Hospital from January 2018 to October 2021 were included and divided into exophthalmos group and non-exophthalmos group based on whether the patients had postural exophthalmos. Intralesional bleomycin injection and N-butyl-2-cyanoacrylate glue embolization were performed. The preoperative and postoperative visual acuity, the dosages of bleomycin and isobutyl cyanoacrylate glue, pathological results, imaging findings and remission rate were recorded and analyzed. The Chi-square test, Wilcoxon signed rank analysis and Mann-Whitney U test were used for statistical analysis. Results: A total of 58 patients (58 eyes)were included, and there were 22 males (37.9%) and 36 females (62.1%). Nineteen (32.8%) patients had postural exophthalmos, and 39 (67.2%) patients did not suffer postural exophthalmos. The patient's age of the two groups was 39.0 (28.0, 54.5) years vs. 14.0 (5.7, 26.5) years, with a statistically significant difference (Z=-3.96, P<0.001). There was no significant difference in gender, eye laterality, follow-up time and the disease course between the two groups (all P>0.05). During the operation, the dosage of bleomycin was 15 000 (13 500, 15 000) U in the exophthalmos group, and 15 000 (9 000, 16 500) U in the non-exophthalmos group (Z=-0.70, P=0.944). The dosages of N-butyl-2-cyanoacrylate glue were 2.8 (1.0, 3.0) ml and 1.7 (1.0, 2.2) ml, respectively, in the two groups, with no significant difference (Z=-1.11, P=0.268). There was no visual impairment in both groups, while the visual acuity in 5 patients without postural exophthalmos was improved postoperatively. The imaging examination results showed no difference in the malformed vascular area before and after the treatment in the exophthalmos group [384.0 (329.0, 458.0) mm2 vs. 330.5 (271.6, 356.7) mm2; Z=-1.26, P=0.208], but a significantly decreased area after the treatment in the non-exophthalmos group [960.8 (822.1, 1058.3) mm2 vs. 311.6 (164.6, 361.6) mm2; Z=-2.67, P=0.008]. All patients had no obvious local or systemic adverse reactions during the follow-up. The pathology reports showed vascular malformations in all 15 specimens obtained from the exophthalmos group, as well as vascular malformations in 41.0% (16/39) of specimens and venous lymphatic malformations in 59.0% (23/39) of specimens from the non-exophthalmos group. Thirty-nine patients had complete remission (67.2%), 19 patients had partial remission (32.8%), and the effective treatment rate was 100%. Conclusion: Bleomycin lavage combined with N-butyl-2-cyanoacrylate glue embolization can achieve good therapeutic effects on orbital vascular malformations.

Abstract
Objective: To estimate the value of multidetector computed tomography angiography (MDCTA) and image analysis before bronchial artery embolization (BAE) in the treatment of hemoptysis. Methods: A total of 165 patients with hemoptysis who underwent BAE at the Department of Interventional Radiology of Xiangyang Central Hospital from August 2017 to June 2021 were retrospectively analyzed and divided into two groups: MDCTA group [with preoperative MDCTA, 88 patients,63 males and 25 females,aged 23 to 87(62.6±12.3) years] and control group [77 patients, 52 males and 25 females, aged 26 to 83 (59.8±12.7) years]. The number of bronchial arteries and non-bronchial systemic arteries, and clinical success rate were compared between the two groups. Comparisons within groups were performed using the t-test or nonparametric paired Wilcoxon test for quantitative data with paired design, while comparisons between groups were performed using the t-test for the mean of two independent samples or the nonparametric Mann-Whitney U test for independent samples and comparisons between groups were performed using the chi-square test. Results: The number of orthotopic and ectopic bronchial arteries found in BAE procedure in the MDCTA group was significantly higher than that in the control group [1.77±0.72 vs. 1.42±0.82, P=0.003; 0 (0, 0) vs. 0 (0, 0), P=0.033, respectively]; in the MDCTA group, the numbers of orthotopic and ectopic bronchial arteries found by MDCTA were significantly higher than those found in BAE procedure [2.22±0.63 vs. 1.77±0.72, P<0.001; 0 (0, 0) vs. 0 (0, 0), P=0.005, respectively]. The number of non-intercostal arteries found by MDCTA in the MDCTA group was significantly higher than that in the control group [0 (0, 0) vs. 0 (0, 0), P=0.038]. Hemostatic success was significantly higher in the MDCTA group than that in the control group (88.6% vs. 68.8%, P=0.002). Conclusions: MDCTA and image analysis help to detect more bronchial arteries and improve the hemostatic success rate before bronchial artery embolization in the treatment of hemoptysis.

Abstract
Objective: To investigate the efficacy, and safety of omalizumab in the treatment of eosinophilic granulomatous with polyangiitis (EGPA) with asthma as the first symptom. Method: The clinical characteristics of 22 EGPA patients with asthma as the first symptom treated with omalizumab in the First Affiliated Hospital of Guangzhou Medical University from March 2018 to December 2020 were retrospectively analyzed. The asthma control test (ACT) score, the frequency of asthma exacerbation (AE), the Birmingham Vasculitis Activity Score (BVAS), the variation rate of peak expiratory flow (PEF), the percentage of PEF to predicted value of PEF (PEFpred%), the percentage of forced expiratory volume in first second (FEV1) to predicted value of FEV1 (FEV1pred%), the dosage of oral corticosteroid (OCS) and other clinical data [M(Q1, Q3)] were collected before and after treatment, to observe the efficacy and adverse reactions of omalizumab. Results: There were 22 subjects recruited in this study. The median age was 42 (22-70) years. Eleven of the patients were males. After treated with omalizumab for 4 months, there were 68.2%(15/21) of patients who responded to the treatment. In the response group (n=15), the patients' ACT score increased from 19.0 (16.5, 21.0) to 23.0 (21.5, 24.0) (P=0.001). The frequency of AE decreased from 0.7 (0.3, 1.0) to 0 (0, 0.7) per four mouths (P<0.001). The BVAS decreased from 4.0 (2.0, 6.0) to 2.0 (2.0, 4.0) (P=0.007). The variation rate of PEF decreased from 18.8% (14.0%, 27.7%) to 9.2% (6.8%, 11.9%) (P=0.007). The PEFpred% increased from 80.8% (73.5%, 90.7%) to 100.5% (79.4%, 114.0%) (P=0.005). The maintenance dosage of OCS reduced from 15.0 (10.0, 20.0) mg/d to 8.8 (5.0, 10.0) mg/d (P=0.005). The level of baseline eosinophil in peripheral blood of patients in non-response group was higher than that in response group [11.4% (9.2%, 22.6%) vs 3.4% (1.1%, 6.5%), P<0.05]. A total of 190 injections were performed in 22 patients, and only 4 patients (2.1%) had adverse reactions after a single injection of omalizumab, such as dizziness, swelling of injection site and pruritus. The adverse reactions were tolerable. Conclusions: Omalizumab has certain curative effect on EGPA, can reduce asthmatic symptoms and OCS maintenance dosage, and has a good safety profile. The rate of response to the treatment is higher in patients with mild eosinophilic inflammation.

Abstract
Objective: To fit and predict the trend of COVID-19 epidemics in the United States (USA) and the United Kingdom (UK), and analyze the effect of vaccination. Methods: Based on the SEIR dynamic model, considering the presymptomatic infections, isolation measures, vaccine vaccination coverage, etc., we developed a SEIR with vaccine inoculation, Presymptomatic infectious, unconfirmed infectious, hospital isolation and domiciliary isolation dynamics model. The publicly released incidence data of COVID-19 from November 6, 2020 to January 31, 2021 in USA and from November 23, 2020 to January 31, 2021 in UK were used to fit the model and the publicly released incidence data of COVID-19 from February 1, 2021 to April 1 were used to evaluate the predicting power of the model by software R 4.0.3 and predict changes in the daily new cases in the context of different vaccination coverage. Results: According to the cumulative confirmed cases, the fitting bias and the predicting bias of the SVEPIUHDR model for USA and UK were less than 5%, respectively. From the model prediction results, the cumulative cases after COVID-19 vaccination in USA in early April reached 31 864 970. If there had not had such vaccination, the cumulative cases of COVID-19 would have reached to 35 317 082, with a gap of more than 3.4 million cases. In UK, the cumulative cases of COVID-19 after the vaccination was estimated to be 4 195 538 in early April, compared with 4 268 786 cases if no COVID-19 vaccination had been provided, there would have heen a gap of more than 70 000 cases. Conclusion: SVEPIUHDR model shows a good prediction effect on the epidemic of COVID-19 in both USA and UK.

Abstract
Objective: To describe and evaluate the surgical effect and prognosis of nasal endoscopic modified mucosal flap technique for repair of congenital choanal atresia in newborns and infants. Methods: The clinical data of 38 newborns and infants with congenital choanal atresia who underwent nasal endoscopic surgery in Beijing Children's Hospital between January 2016 and May 2018 were retrospectively analysed, including 13 males and 25 females. The age ranged from 5 days to 3 years old at the time of operation (15 cases were newborns). The clinical data, imaging data, treatment effect and prognosis were collected. According to the different surgical methods, the patients were divided into the conventional operation group and the modified mucosal flap technique group. The designs of the modified mucosal flap technique were designed according to the type of congenital choanal atresia. The cross-over L-shaped flaps were performed in patients with unilateral atresia, and the mirrored L-shaped flaps were performed in patients with bilateral atresia. All the patients were followed up for 2-3 years, and the follow-up parameters included the times of operations, length of hospital stay, restenosis rate and incidence of complications. Study data was analyzed using SAS version 9.4 statistical software. Results: Sixteen cases underwent conventional operation while 22 patients underwent modified mucosal flap technique under nasal endoscope. The lightest weight (2 200 g) and the youngest age (5 days) of the patients came from the modified mucosal flap technique group. Compared with the conventional operation group under nasal endoscope, the modified mucosal flap technique group had fewer times of operations (1.14±0.47 vs 2.69±1.20, t=5.552, P<0.001), shorter hospital stay ((7.70±3.22) d vs (14.37±19.16) d, t=2.960, P=0.005), lower rate of postoperative restenosis (9.1% vs 43.8%, χ²=6.156, P=0.013), and lower rate of the incidence of complications (13.6% vs 43.8%, χ²=5.955, P=0.015), the differences were statistically significant. Conclusion: The nasal endoscopic modified mucosal flap technique is feasible for repairing congenital choanal atresia in newborns and infants, which can significantly reduce the incidence of postoperative restenosis and complications.

Abstract
OBJECTIVE Small nucleolus RNA Host Gene 8 (SNHG8) belongs to a subgroup of long non-coding RNAs. SNHG8 is upregulated in many cancers, such as gastric cancer, liver cancer, and esophageal squamous cell cancer. However, whether SNHG8 is abnormally expressed in breast cancer and its biological functions remain unclear. Therefore, our research intended to determine the expression status of SNHG8 in breast cancer, explore the effects of SNHG8 on the development of breast cancer, and investigate the potential molecular mechanisms in cancer progression. PATIENTS AND METHODS The expression levels of SNHG8 were detected in tissue samples and cell lines via qRT-PCR. The effects of SNHG8 on viability of breast cancer cells were detected via CCK-8, EdU, transwell, and flow cytometry analyses. RESULTS qRT-PCR results showed that the expression level of SNHG8 was significantly upregulated in tumor tissues and cell lines. Gene functional studies showed that the downregulation of the expression level of SNHG8 significantly inhibited the breast cancer cells migration and invasion, and induced apoptosis. Meanwhile, we found that SNHG8 served as an inhibitor of miR-634 in tumor tissues. SNHG8 may participate in the malignancy of breast cancer by sponging the miR-634 to increase the expression level of ZBTB20. CONCLUSIONS The SNHG8-miR-634-ZBTB20 pathway may be a potential target for the treatment of breast cancers.

Abstract
A simple, efficient scheme was developed to obtain near-gigaelectronvolt electron beams with energy spreads of few per-mille level in a single-stage laser wakefield accelerator. Longitudinal plasma density was tailored to control relativistic laser-beam evolution, resulting in injection, dechirping, and a quasi-phase-stable acceleration. With this scheme, electron beams with peak energies of 780-840 MeV, rms energy spreads of 2.4‰-4.1‰, charges of 8.5-23.6 pC, and rms divergences of 0.1-0.4 mrad were experimentally obtained. Quasi-three-dimensional particle-in-cell simulations agreed well with the experimental results. The dechirping strength was estimated to reach up to 11 TeV/mm/m, which is higher than previously obtained results. Such high-quality electron beams will boost the development of compact intense coherent radiation sources and x-ray free-electron lasers.

Abstract
OBJECTIVE Long non-coding RNA LINC00173 (LINC00173) has been shown to facilitate the progression of a number of malignancies. In this study, we aimed to investigate the function of LINC00173 on prostate cancer (PCa) and discover the potential regulatory mechanism. PATIENTS AND METHODS RT-PCR was used to determine the levels of LINC00173, miR-338-3p and Rab25 in PCa patients and cell lines. The clinical significance of LINC00173 was statistically analyzed in 124 PCa patients. CCK-8, colony formation, transwell, scratch wound, Ethynyldeoxyuridine (EdU) assays and flow cytometry assays were used to detect the proliferation, apoptosis, invasion and migration of PCa cells. The mechanism of LINC00173 action was explored through bioinformatics, RNA pull-down assays and Luciferase reporter assays. RESULTS We observed that the expression of LINC00173 and Rab25 was distinctly upregulated in both PCa specimens and cell lines, while miR-338-3p expression was significantly down-regulated. High LINC00173 expression was associated with Gleason score, preoperative PSA level and reduced patient survivals. Functional assays revealed that knockdown of LINC00173 suppressed the proliferation, migration and invasion of PCa cells, and promoted apoptosis. Mechanistically, LINC00173 acted as a competitive endogenous RNA in PCa and increased Rab25 expressions via sponging miR-338-3p. Moreover, LINC00173 promoted PCa progression by interacting with miR-338-3p and Rab25. CONCLUSIONS Our findings, for the first time, identified a novel PCa-related lncRNA, LINC00173 which might serve as an oncogene in PCa. The discovery of the LINC00173/miR-338-3p/Rab25 pathways provided new thinking for the treatments of PCa.

Abstract
Objective: Peritoneal carcinomatosis refers to a group of heterogeneous (primary or secondary) malignancies in the surface of the peritoneum. Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is a comprehensive treatment strategy aiming at peritoneal carcinomatosis. This study analyzed the efficacy and safety of CRS+HIPEC in patients with peritoneal carcinomatosis, and explored prognostic factors. Methods: In this descriptive case-series study, the clinicopathological data of 1384 consecutive patients with peritoneal carcinomatosis treated in Zhongnan Hospital of Wuhan University (330 patients) and Shijitan Hospital of Capital Medical University (1054 patients) from January 2004 to January 2020 were collected retrospectively. Treatment patterns of CRS+HIPEC characteristics (operative time, number of resected organs, number of stripped peritoneum, number of anastomosis, and HIPEC regimens), safety [blood loss volume, postoperative severe adverse event (SAE) and treatment outcome], survival time and prognostic factors influencing survival were analyzed. The SAE was defined as grade III-IV adverse event according to the Peritoneal Surface Oncology Group International Textbook. Perioperative period was defined from the day of CRS+HIPEC to postoperative 30th day. OS was calculated from the day of CRS+HIPEC to the date of death or the last follow-up. Kaplan-Meier method was used for survival analysis, and log-rank test was used for comparison between groups. Cox regression model was used to identify the prognostic factors. Results: Among 1384 peritoneal carcinomatosis patients, 529 (38.2%) were male; median age was 55 (10-87) years old; median body mass index (BMI) was 22.6 kg/m(2); peritoneal carcinomatosis of 164 (11.8%) patients were from gastric cancer, 287 (20.7%) from colorectal cancer, 356 (25.7%) from pseudomyxoma peritonei, 90 (6.5%) from malignant peritoneal mesothelioma, 300 (21.7%) from gynecological cancer or primary peritoneal carcinoma, and 187 (13.5%) from retroperitoneal sarcoma, lung cancer, breast cancer, and other rare tumors. The median duration of CRS+HIPEC was 595 (90-1170) minutes, median number of resected organs was 2 (0-10), median number of resected peritoneal area were 4 (0-9), median peritoneal cancer index (PCI) was 21(1-39). Completeness of cytoreduction (CC) score of 0-1 was observed in 857 cases (61.9%). Regarding HIPEC regimens, there were 917 cases (66.3%) with cisplatin plus docetaxel, 183 cases (13.2%) with cisplatin plus mitomycin, 43 cases (3.1%) with adriamycin plus ifosfamide, and the other 240 cases (17.3%) with modified regimens. Perioperative SAE developed in 331 peritoneal carcinomatosis patients (23.9%) with 500 cases, of whom 21 patients (1.5%) died during the perioperative period due to ineffective treatment, while the others recovered after active treatment. During median follow-up time of 8.6 (0.3-82.7) months, there were 414 deaths (29.9%). The median OS was 38.2 months (95% CI: 30.6-45.8), and the 1-, 3-, 5-year survival rate was 73.5%, 50.4% and 39.3%, respectively. The median OS of peritoneal carcinomatosis patients from gastric cancer, colorectal cancer, pseudomyxoma peritonei, malignant peritoneal mesothelioma and female genital cancer or primary peritoneal carcinomatosis was 11.3 months (95% CI: 8.9-13.8), 18.1 months (95% CI: 13.5-22.6), 59.7 months (95% CI: 48.0-71.4), 19.5 months (95% CI: 6.0-33.0) and 51.7 months (95% CI: 14.6-88.8), respectively, and the difference among groups was statistically significant (P<0.001). Univariate and multivariate analyses revealed that the primary gastric cancer (HR=4.639, 95% CI: 1.692-12.724), primary colorectal cancer (HR=4.292, 95% CI: 1.957-9.420), primary malignant peritoneal mesothelioma (HR=2.741, 95% CI: 1.162-6.466), Karnofsky performance status (KPS) score of 60 (HR=4.606, 95% CI: 2.144-9.895), KPS score of 70 (HR=3.434, 95% CI: 1.977-5.965), CC score of 1 (HR=2.683, 95% CI: 1.440~4.999), CC score of 2-3 (HR=3.661,95% CI: 1.956-6.852) and perioperative SAE (HR=2.588, 95% CI: 1.846-3.629) were independent prognostic factors influencing survival with statistically significant differences (all P<0.05). Conclusions: CRS+HIPEC is an effective integrated treatment strategy for patients with peritoneal carcinomatosis, which can prolong survival with acceptable safety. Preoperative evaluation of patients' general condition is necessary and CRS+HIPEC should be carefully considered to perform for patients with preoperative KPS score <80. During the operation, the optimal CRS should be achieved on condition that safety is granted. In addition, it is necessary to prevent perioperative SAE to reduce the risk of death in peritoneal carcinomatosis patients.

Abstract
Objective: To summarize clinical features and our experience of the diagnosis and treatment of pediatric nasal neuroglial heterotopia (NGH). Methods: Clinical data of 13 nasal NGH patients in Beijing Children's Hospital from August 2014 to October 2019 were retrospectively reviewed, including 9 boys and 4 girls, aged from 1 to 38 months with median age of 5 months. Radiological workups and excision of nasal NGH under general anesthesia were performed for all patients. B ultra-sound and MRI were performed for all external and mixed lesions, while ultra-low-dose CT scan and MRI for all intranasal type. Surgical approaches were dependent on location and extent of the lesions according to radiographic workup, including extranasal or transnasal endoscopic approach. Patients were followed up regularly after operation to evaluate the effect. Initial presentation, locations, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eight nasal NGH patients presented with an internal nasal mass and nasal obstruction, which belonged to intranasal type. Three patients presented with an external nasal mass which belonged to extranasal type and 2 patients had mixed lesions. The sites included nasal dorsum (n=5), anterior to the middle turbinate (n=5) and olfactory cleft (n=3). Surgical resections were done through median rhinotomy approach (n=5) or transnasal endoscopic approach (n=8). All the operations were successful and no complication occurred. All cases were followed up from 3 to 65 months. No recurrence was encountered. Conclusions: Nasal NGH is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and MRI is essential for evaluation of the location, extent of the disease and for making the surgical plan. Treatment requires complete surgical excision.

Abstract
OBJECTIVE Mutations in phosphatase and tensin homologue deleted on chromosome 10 (PTEN), a tumor suppressor gene, lead to altered sensitivity to drugs and radiation in various types of cancer. Restoring PTEN expression in tumor cells can increase radiosensitivity by inhibiting the repair of DNA double-strand breaks (DSBs). Thus, determining the mechanism of action of this protein may lead to novel therapeutic strategies. MATERIALS AND METHODS In this study, we transduced U251 cells with a lentiviral vector expressing PTEN to examine the mechanism of radiosensitization. Specifically, we examined the formation of radiation-induced DNA DSBs and apoptosis, as well as the expression of several proteins involved in repairing DSBs (p53, ataxia-telangiectasia mutated, DNA-dependent protein kinase C, Ku70-80). RESULTS Our results showed that PTEN transduction sensitized U251 cells to X-rays, increasing the number of DSBs per cell and fraction of cells undergoing apoptosis. Additionally, the average size of γH2AX nuclear foci was increased following irradiation. These findings were accompanied by a PTEN-dependent irradiation-independent increase in p53 levels and decrease in phosphorylated Ku70/80 levels. CONCLUSIONS Our results suggest that PTEN affects radiosensitivity by reducing DSB repair and by enhancing the p53 pathway, leading to increased apoptosis.

Abstract
Objective: To explore the surgical effect and experience of endoscope-assisted excision for congenital nasal dermoid and sinus cyst (NDSC) in children. Methods: Fifty-three patients with congenital NDSC treated in Beijing Children's Hospital from January 2007 to December 2018 were retrospectively reviewed, including 30 boys and 23 girls, with the age ranging from 9 to 145 months (mean age 35.6 months). The ultra-low-dose CT scan and MRI of the paranasal sinuses were performed for all patients. Excisions of NDSC under general anesthesia were performed for all patients, and surgical approaches were dependent on location and extent of the lesions according to radiographic workups. All intra-osseous patients and complicated superficial cases underwent surgical excision of NDSC and nasal reconstruction with the assistance of endoscope. Initial presentation, medical history, imaging workups, surgical approaches, complications, rates of recurrence and cosmetic outcomes were evaluated. Descriptive statistics was used for the results analysis. Results: Among 53 cases, the most common presentation included a nasal-glabella mass (n=21, 39.6%), a dorsal punctum (n=13, 24.5%) and a dorsal mass (n=9, 17.0%). The sites of NDSC included nasal glabella (n=22, 41.5%), nasal bridge (n=27, 50.9%) and nasal tip (n=4, 7.5%). Of all patients, 24 cases (45.3%) had superficial lesions, 19 cases (35.8%) had intraosseous extension into the frontonasal bones, 10 cases (18.9%) extended intracranially but remained extradural. Surgical approaches included transverse incision (n=22, 41.5%), minimal midline vertical incision (n=27, 50.9%) and external rhinoplasty (n=4, 7.5%). All NDSC were successfully excised and no nasal reconstruction needed. All cases were followed up from 9 to 151 months with a mean of 67.3 months. Five patients (9.4%) with recurrence were observed and were managed successfully with reoperation. During the follow-up, no nasal deformity was noted, and cosmetic outcome was favorable for all patients. Conclusion: Endoscope-assisted excision has the advantage of clear vision, small trama and low recurrence rate for children with NDSC.

Abstract
Objective: To understand the provision of preventive medicine curriculum system in the training programs of clinical medicine in the era of Healthy China. Methods: A total of 36 training programs of clinical medicine were selected from different areas of China for a statistical analysis on their basic information, involvement of concept of preventive medicine in program objectives, and provision of preventive medicine curriculum system. Results: Of all the 36 training programs of clinical medicine, 22(61%) have no mentions of prevention medicine in their program objectives; only one university's training program states preventive medicine together with basic medicine and clinical medicine as one of the three main disciplines. The total class hours for the core courses of preventive medicine (hygiene, medical statistics, epidemiology, evidence-based medicine, and social medicine) range from 80 to 252, with an average of (156.7±43.2) hours. The average percentage of class hours for preventive medicine courses among the total class hours is 4.3%±1.1% (range: 2.5%-7.5%), and obvious differences exist among universities. Conclusions: In current training programs of clinical medicine, the proportion of prevention medicine curriculum is insufficient, the percentage of hours for preventive medicine course is very low, and the differences among various universities are obvious. It is urgently needed to strengthen preventive medicine curriculum in training programs for clinical medical students in new era. It is suggested to further promote the concept of putting prevention first, improve the curriculum system of clinical medicine, intensify the integrated development preventive medicine and clinical medicine and pay attention to clinical research ability enhancement for the further improvement of training program of clinical medicine.

Abstract
Background Targeting the immune checkpoint pathway has demonstrated antitumor cytotoxicity in treatment-refractory head and neck squamous cell carcinoma (HNSC). To understand the molecular mechanisms underpinning its antitumor response, we characterized the immune landscape of HNSC by their tumor and stromal compartments to identify novel immune molecular subgroups. Patients and methods A training cohort of 522 HNSC samples from the Cancer Genome Atlas profiled by RNA sequencing was analyzed. We separated gene expression patterns from tumor, stromal, and immune cell gene using a non-negative matrix factorization algorithm. We correlated the expression patterns with a set of immune-related gene signatures, potential immune biomarkers, and clinicopathological features. Six independent datasets containing 838 HNSC samples were used for validation. Results Approximately 40% of HNSCs in the cohort (211/522) were identified to show enriched inflammatory response, enhanced cytolytic activity, and active interferon-γ signaling (all, P < 0.001). We named this new molecular class of tumors the Immune Class. Then we found it contained two distinct microenvironment-based subtypes, characterized by markers of active or exhausted immune response. The Exhausted Immune Class was characterized by enrichment of activated stroma and anti-inflammatory M2 macrophage signatures, WNT/transforming growth factor-β signaling pathway activation and poor survival (all, P < 0.05). An enriched proinflammatory M1 macrophage signature, enhanced cytolytic activity, abundant tumor-infiltrating lymphocytes, high human papillomavirus (HPV) infection, and favorable prognosis were associated with Active Immune Class (all, P < 0.05). The robustness of these immune molecular subgroups was verified in the validation cohorts, and Active Immune Class showed potential response to programmed cell death-1 blockade (P = 0.01). Conclusions This study revealed a novel Immune Class in HNSC; two subclasses characterized by active or exhausted immune responses were also identified. These findings provide new insights into tailoring immunotherapeutic strategies for different HNSC subgroups.

Abstract
Periodically ordered arrays of vertically aligned Si nanowires (Si NWs) are successfully fabricated by nanosphere lithography combined with metal-assisted chemical etching. By adjusting the etching time, both the nanowires' diameter and length can be well controlled. The conductive properties of such Si NWs and particularly their size dependence are investigated by conductive atomic force microscopy (CAFM) on individual nanowires. The results indicate that the conductance of Si NWs is greatly relevant to their diameter and length. Si NWs with smaller diameters and shorter lengths exhibit better conductive properties. Together with the I-V curve characterization, a possible mechanism is supposed with the viewpoint of size-dependent Schottky barrier height, which is further verified by the electrostatic force microscopy (EFM) measurements. This study also suggests that CAFM can act as an effective means to explore the size (or other parameters) dependence of conductive properties on individual nanostructures, which should be essential for both fabrication optimization and potential applications of nanostructures.

Abstract
The development of digestive organs and the establishment of gut microbiota in pullets play an important role throughout life. This study was conducted to investigate the effects of Bacillus subtilis (BS) on growth performance, intestinal function and gut microbiota in pullets from 0 to 6 weeks of age. Hy-line Brown laying hens (1-day-old, n = 504) were randomly allotted into four diets with a 2 × 2 factorial design: (1) basal diet group (control); (2) antibiotics group (AGP), the basal diet supplemented with 20 mg/kg Bacitracin Zinc and 4 mg/kg Colistin Sulphate; (3) BS group, the basal diet supplemented with 500 mg/kg BS and (4) mixed group, the basal diet supplemented with both AGP and BS. As a result, when BS was considered the main effect, BS addition (1) reduced the feed conversion ratio at 4 to 6 weeks (P < 0.05); (2) decreased duodenal and jejunal crypt depth at 3 weeks; (3) increased the villus height : crypt depth (V : C) ratio in the duodenum at 3 weeks and jejunal villus height at 6 weeks and (4) increased sucrase mRNA expression in the duodenum at 3 weeks as well as the jejunum at 6 weeks, and jejunal maltase and aminopeptidase expression at 3 weeks. When AGP was considered the main effect, AGP supplementation (1) increased the V : C ratio in the ileum at 3 weeks of age; (2) increased sucrase mRNA expression in the duodenum at 3 weeks as well as the ileum at 6 weeks, and increased maltase expression in the ileum. The BS × AGP interaction was observed to affect average daily feed intake at 4 to 6 weeks, and duodenal sucrase and jejunal maltase expression at 3 weeks. Furthermore, dietary BS or AGP addition improved caecal microbial diversity at 3 weeks, and a BS × AGP interaction was observed (P < 0.05) for the Shannon and Simpson indexes. At the genus level, the relative abundance of Lactobacillus was found to be higher in the mixed group at 3 weeks and in the BS group at 6 weeks. Moreover, Anaerostipes, Dehalobacterium and Oscillospira were also found to be dominant genera in pullets with dietary BS addition. In conclusion, BS could improve intestinal morphology and change digestive enzyme relative expression and caecum microbiota, thereby increasing the efficiency of nutrient utilization. Our findings suggested that BS might have more beneficial effects than AGP in the study, which would provide theoretical evidence and new insight into BS application in layer pullets.

Abstract
Objective: To investigate general condition of children's rheumatic disease associated medical resources in Fujian Province. Methods: This questionnaire-based survey was conducted in 19 hospitals in Fujian province from December 2, 2018 to May 1, 2019. The questionnaire was designed to survey the general condition of the medical resources and the hospitalization of patients with rheumatic diseases from January 1, 2014 to December 1, 2018. Results: In the 19 hospitals, there were 15 general hospitals and 4 children's hospitals, and only 5 hospitals had children's rheumatic specialist clinic. There were only 53-62 beds for rheumatic disease patients in the 19 hospitals, accounting for 1.7%-2.0% of the total inpatient beds (3 137). There are 29 pediatric rheumatologists in total, accounting for 2.6% (29/1 120) of the total pediatricians. In the past five years, 613 patients with rheumatic diseases, accounting for 0.1% (613/625 214) of total hospitalized patients, were treated in these hospitals. Among them, 201 had juvenile idiopathic arthritis, 295 had systemic lupus erythematosus, 39 had dermatomyositis, 7 had scleroderma, and 57 had inflammatory bowel disease, 9 had Sjogren's syndrome, 5 had Behcet's disease, and none had overlap syndrome or mixed connective tissue disease. Conclusion: The medical resources of children rheumatic diseases in Fujian province are insufficient which need to be developed.

Abstract
OBJECTIVE To investigate whether metformin can relieve acute respiratory distress syndrome (ARDS). Its potential mechanism was also explored. MATERIALS AND METHODS The ARDS model was established by injecting LPS into mice that received metformin in advance and the mice in the control group. Pulmonary edema was detected by W/D ratios (wet-to-dry weight ratios), and the vascular exudation was reflected by the protein content and cell number of alveolar lavage fluid. Meanwhile, MPO (myeloperoxidase) activity assay was performed to analyze the neutrophil aggregation. The expression of inflammatory cytokines, including TNF-α, IL-1β, IL-6, and IL-17, were detected by enzyme-linked immunosorbent assay (ELISA). This series of experiments reflected the alleviation effect of metformin on ARDS. To further study the mechanism, we cultured alveolar macrophages (NR8383) in vitro and treated them with LPS and metformin. Western blot was used to detect the phosphorylation levels of p38, ERK, NF-kB, and SIRT1 expression level. Bioinformatics method was then used to predict the binding of miR-138 to SIRT1. The mRNA and protein expression of SIRT1 was detected in NR8383 cells transfected with miR-138 inhibitor. The dual luciferase gene reporter assay was used to detect the relative luciferase activities of miR-138 and SIRT1. RESULTS Pulmonary edema, vascular exudation, and neutrophil accumulation were observed in the ARDS model mice, and the levels of inflammatory cytokines including TNF-α, IL-1b, IL-6, and IL-17 were significantly increased. After metformin treatment, these pulmonic damage indicators were found to be partially reversed. At the same time, metformin could significantly reduce LPS-induced death. After NR8383 was treated with metformin and LPS, the expression of SIRT1 was higher than that of LPS treatment alone, but the expression of p-p38, p-ERK, and p-NF-κB was significantly decreased. After the addition of metformin in NR8383 after LPS treatment, the expression level of miR-138-5p was significantly decreased, and miR-138-5p was confirmed to target SIRT1 and regulate its expression. CONCLUSIONS Metformin could reduce LPS-induced pulmonic injury and increase expression of inflammatory factors. A possible mechanism might be that metformin-induced low expression of mir-138-5p could target SIRT1 to increase its expression and suppress the MAPK pathway, thus alleviating ARDS.

Abstract
Bone fractures are a medical condition where the continuity of the bone is broken due to a fall or accident. The fracture may also be the result of medical conditions such as osteoporosis, cancers of bone or osteogenesis imperfect. During the bone fracture healing process, the mesenchymal stem cells (undifferentiated connective tissue cells) are recruited from local and systemic sources. The modulation of mesenchymal cell migration to the fractured site is the desired goal. Still, there are many processes that are still required to be studied and analyzed. We aimed to consolidate and review the available information on this topic.

Abstract
In 1872, New England Hospital for Women and Children was established as the first hospital nursing school in the United States, which became the beginning of modern nursing education in the United States. Its establishment and development were influenced by Nightingale's nursing educational thought, and were also closely related to the work of two American female doctors. The establishment of New England Hospital for Women and Children nursing school made it possible to train professional nurses through formal nursing education, and laid the foundation for the development of nursing education in the United States.

Abstract
Objective: To investigate the immune reconstruct regularity profile of KIR2DL1 and KIR3DL1 in unrelated-donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) with KIR-AA genotype. Method: 75 donor-recipient pairs were performed by KIR genotying using PCR-SSP, and all donors were identified with KIR-AA genotype. Dynamic detections (including unrelated-donor on the day of transplantation and the recipient each month post allo-HSCT) of the expression of KIR2DL1/3DL1 on NK cell and mRNA level were performed in 291 cases using flow cytometry (FCM) and real-time fluorescent quantitation PCR (RT-qPCR) . Result: ①The median expression of KIR2DL1 in unrelated-donor on transplant's day was 21.60%, the median expression of KIR2DL1 in recipient 1M, 2M, 3M and 3-6M after transplantation were 7.40%, 12.00%, 16.92%, 17.64% respectively. The median expression of KIR2DL1 in unrelated-donor on transplant's day was 265.14 copies/10 000abl copies, the median expression of KIR2DL1 in recipient 1M, 2M, 3M, 3-6M, 6-9M, 9-12M after transplantation were 332.17, 438.31, 723.25, 414.17, 180.76 and 234.67 copies/10 000abl copies respectively. The median expression of KIR2DL1 on NK cells and mRNA level gradually increased at all time points after transplantation, and reached the highest expression at 3 months after transplantation. But mRNA expression levels increased earlier than NK cell membrane proteins. ②The median expression of KIR3DL1 in unrelated-donors on transplant's day was 18.56%, the median expression of KIR3DL1 in recipient 1M, 2M, 3M, 3-6M after transplantation were 23.83%, 22.57%, 23.02%, 21.60% respectively. The median expression of KIR3DL1 in unrelated-donor on transplant's day was 572.29 copies/10 000abl copies, the median expression of KIR3DL1 in recipient 1M, 2M, 3M, 3-6M, 6-9M, 9-12M after transplantation were 1 233.74, 1 140.42, 876.73, 1 057.07, 739.02 and 514.43 copies/10 000abl copies respectively. The median expression of KIR3DL1 on NK cells and mRNA level were higher than donors at 1 month after transplantation, and stable expression at all time points after transplantation, so mRNA and NK cell membrane proteins expression increased at the same time. Conclusion: The immune reconstruct regularity of KIR2DL1 and KIR3DL1 gene were different, which provided an experimental basis for selecting the best time to detect the expressions of KIR2DL1 and 3DL1 after transplantation.

Abstract
Objective: To determine the clinical value of droplet digital polymerase chain reaction (ddPCR) method to detect plasma circulating tumor DNA (ctDNA) epidermal growth factor receptor (EGFR) mutations in advanced pulmonary adenocarcinoma. Methods: One hundred and thirty six patients with advanced pulmonary adenocarcinoma diagnosed in the Beijing Chest Hospital were collected from May 2015 to April 2017 for initial treatment. EGFR gene mutation in the plasma ctDNA was detected by both ddPCR and amplification refractory mutation system (ARMS) assays. EGFR gene mutation in the tumor tissue was detected by ARMS assay. Patients with EGFR sensitive mutations received first-line oral treatment with EGFR tyrosine kinase inhibitor (EGFR-TKI) drugs. The Kaplan-Meier survival analysis was used to compared the progression-free survival (PFS) in EGFR gene mutated patients detected with different methods. Results: Total of 111 samples (81.6%) were detected with EGFR gene mutations in 136 tumor tissue samples. In the 111 samples, 48 samples were found with exon21 L858R mutation (48/111, 43.2%), 59 samples were found with exon19 deletion mutations (59/111, 53.2%), and 4 cases were found with other mutations (4/111, 3.6%). Using tumor specimens as the gold standard, the sensitivity, specificity, and concordance rate of ARMS assay were 58.6%, 96.0%, and 65.4%, respectively; and those in ddPCR assay were 79.3%, 100%, and 83.1%, respectively; the coincidence rate was 83.1% (Kappa=0.685, P<0.001). Kaplan-Meier survival analysis showed that patients with EGFR gene mutation detected by both ddPCR and ARMS methods had shortest PFS when compared with those in patients detected positive with a single method of ddPCR or ARMS assay (11.6 moths vs 14.8 months, χ(2)=2.517, P=0.026). Conclusions: ddPCR is a reliable technology with high sensitivity and high specificity to detect EGFR gene mutations in plasma ctDNA in patients with advanced pulmonary adenocarcinoma. Plasma EGFR gene mutation may predict the efficacy of EGFR-TKI drugs.

Abstract
OBJECTIVE To explore ANGPTL4 expressions in patients with gestational diabetes mellitus (GDM) and its underlying mechanism. PATIENTS AND METHODS We first detected serum expressions of ANGPTL4 in GDM patients and healthy pregnancies. Subsequently, effects of ANGPTL4 knockdown on apoptosis, proliferation, and cell cycle in 3T3-L1 cells were determined, respectively. Effects of ANGPTL4 on glucose uptake and adipocyte differentiation were also evaluated, respectively. The cytokine secretion in adipocytes transfected with sh-ANGPTL4 was detected by quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Furthermore, effects of ANGPTL4 knockdown on NF-kB and Akt pathway were detected by Western blot. RESULTS ANGPTL4 was down-regulated in serum of GDM patients. In vitro experiments suggested that down-regulated ANGPTL4 inhibited apoptosis and promoted proliferation of 3T3-L1 cells. Meanwhile, down-regulated ANGPTL4 significantly inhibited glucose uptake and Akt pathway. However, ANGPTL4 expression did not affect cell cycle and adipocyte differentiation. Detection of inflammatory cytokines suggested that down-regulated ANGPTL4 resulted in increased expressions of inflammatory cytokines and activation of NF-kB pathway. CONCLUSIONS ANGPTL4 is down-regulated in GDM and may participate in the GDM development by promoting insulin resistance and secretion of inflammatory cytokines.

Abstract
Objective: To investigate the clinical characteristics of extremely severe burn patients complicated with severe inhalation injury caused by dust explosion. Methods: The medical records of 13 extremely severe burn patients complicated with severe inhalation injury in August 2nd Kunshan factory aluminum dust explosion accident, who were admitted to the First Affiliated Hospital of Soochow University on August 2nd, 2014, were retrospectively analyzed. The following indicators were collected: (1) Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score and Sequential Organ Failure Assessment (SOFA) score at post admission hour (PAH) 24. (2) Prognosis, death time, causes of death, and the mortality of patients with different sexes. (3) The number of times of airway electronic bronchoscopy, airway characteristics, and the corresponding onset time. (4) The number and result of microorganism culture of lesion tissue during the leukoplakia formation stage. Detection of Pseudomonas aeruginosa in patients with and without leukoplakia in airway mucosa. Fisher's exact probability test was used to detect the mortality of patients with different sexes. Kappa test was used to detect the relevancy between leukoplakia and Pseudomonas aeruginosa. Results: (1) The APACHE Ⅱ score of patients of this group at PAH 24 was (19±3) points, and the SOFA score was (12±3) points. (2) Eight patients survived, while 5 patients died, and the time of death was 19-46 (34±10) d after injury. The main cause of death was multiple organ dysfunction syndrome, which was secondary to severe infection. One of the 7 male patients and 4 of the 6 female patients died, but there was no significantly statistical difference in mortality between patients of the two sexes (P>0.05). (3) Airway electronic bronchoscopy was performed 4-25 (10±5) times among patients of this group. Hyperemia and edema were found in the airway mucosa of all the 13 patients 2-3 weeks after injury; ulcer was found in the airway mucosa of 5 patients 2-4 weeks after injury; leukoplakia was found in the airway mucosa of 7 patients 4-14 weeks after injury; granulation formed in the airway mucosa of 7 patients 10-15 weeks after injury, and airway patency was affected, which was solved after local clamping or replacement of lengthened tracheal cannula. (4) During the leukoplakia formation stage, 19 cases of microorganism culture were performed basing on airway lesion tissue, and the results were 15 cases of Pseudomonas aeruginosa, 5 cases of Acinetobacter baumannii, 2 cases of Serratia marcescens, as well as 1 case of Stenotrophomonas maltophilia, Burkholderia cepacia, and Proteus mirabilis each. Among 7 patients with airway mucosa leukoplakia, 6 patients were detected with Pseudomonas aeruginosa. Among 6 patients without airway mucosa leukoplakia, 1 patient was detected with Pseudomonas aeruginosa. The appearance of leukoplakia was consistent with the detection of Pseudomonas aeruginosa (Kappa=0.69, P<0.05). Conclusions: Most of these extremely severe burn patients complicated with severe inhalation injury caused by dust explosion survived, and there was no significant gender difference in mortality. Electronic bronchoscopy showed that the early manifestations of airway mucosa were hyperemia and edema, followed by varying degrees of erosion, ulcer, leukoplakia, and granulation formation, etc. Leukoplakia may be relevant to Pseudomonas aeruginosa infection.

Abstract
This study was conducted to evaluate the relative biological value (RBV) of 1α-hydroxycholecalciferol (1α-OH-D3) to 25-hydroxycholecalciferol (25-OH-D3) in one- to 21-day-old broiler chickens fed calcium (Ca)- and phosphorus (P)-deficient diets. On the d of hatch, 450 male Ross 308 broiler chickens were weighed and randomly allotted to 9 treatments with 5 replicates of 10 birds per replicate. The basal diet contained 0.50% Ca and 0.25% non-phytate phosphorus (NPP) but was not supplemented with cholecalciferol (vitamin D3). The levels of Ca and NPP in basal diets were lower than those recommended by NRC (1994). 25-OH-D3 was fed at zero, 1.25, 2.5, 5.0, and 10.0 μg/kg, and 1α-OH-D3 was fed at 0.625, 1.25, 2.5, and 5.0 μg/kg. The RBV of 1α-OH-D3 to 25-OH-D3 based on vitamin D intake was determined by the slope ratio method. Results showed that 25-OH-D3 or 1α-OH-D3 improved the growth performance and decreased the mortality in one- to 21-day-old broilers. A linear relationship was observed between the level of 25-OH-D3 or 1α-OH-D3 and mineralization of the femur, tibia, or metatarsus. The RBV of 1α-OH-D3 to 25-OH-D3 were 234, 253, and 202% when the weight, ash weight, and Ca percentage of femur were used as criteria. The corresponding RBV of 1α-OH-D3 to 25-OH-D3 were 232 to 263% and 245 to 267%, respectively, when tibia and metatarsus mineralization were used as criteria. These data indicate that when directly feeding a hormonally active form of vitamin D as 1α-OH-D3 proportionally less is needed than when using the precursor (25-OH-D3) in diets deficient in Ca and P.

Abstract
1α-Hydroxycholecalciferol (1α-OH-D3) is a vitamin D derivative. The objective of this study was to evaluate the effects of 1α-OH-D3 on the growth and the mRNA expression of vitamin D receptor (VDR) in the small intestine and kidney of chickens. A total of 240 males of one-day-old Ross 308 broilers was randomly assigned to 4 treatments with 5 replicates of 12 birds per replicate. Three levels of 1α-OH-D3 (1.25, 2.5, and 5 μg/kg) were added to a basal diet containing 0.50% calcium (Ca), 0.25% non-phytate phosphorus (NPP), and without supplemental cholecalciferol (vitamin D3). The control diet contained 1.00% Ca, 0.45% NPP, and 25 μg/kg cholecalciferol. Dietary 1α-OH-D3 levels linearly improved the average daily feed intake (ADFI), average daily gain (ADG), femur and tibia mineralization, and plasma Ca concentration, and retained Ca and total phosphorus (tP) amounts in broilers from 1 to 21 d of age (P < 0.05). In addition, 1α-OH-D3 also linearly up-regulated the mRNA expression levels of VDR in the duodenum as well as those of VDR and sodium-phosphate cotransporter NaPi-IIa and NaPi-IIc in the kidney of broilers (P < 0.05). However, 1α-OH-D3 did not affect the mRNA levels of 25-hydroxylase in the liver or NaPi-IIb in the duodenum (P > 0.05). No differences were observed in the ADFI, ADG, bone length, plasma mineral concentration, retained tP amount, or the mRNA levels of the above genes (except for VDR in the kidney) between the birds fed the diet with 5 μg/kg 1α-OH-D3 and the birds fed the control diet (P > 0.05). By contrast, the weight, ash weight, ash percentage, and Ca percentage of the bone, retained Ca amount, and the mRNA level of VDR in the kidney were lower in the birds fed the diet with 5 μg/kg 1α-OH-D3 than in the birds fed the control diet (P < 0.05). These data indicate that 1α-OH-D3 up-regulates the gene expression of VDR in the small intestine and kidney at the transcriptional level, thereby improving the growth performance and bone mineralization of broiler chickens from 1 to 21 d of age.

Abstract
Objective: To investigate the relationship between related factors of intestinal barrier dysfunction in patients with sepsis or septic shock and severity of the condition. Methods: A prospective observational study was conducted in 31 sepsis patients, 28 septic shock patients, and 21 postoperative patients without sepsis (control group) who were admitted to intensive care unit (ICU) of General Hospital of Ningxia Medical University between November 2015 and June 2016. Blood samples were collected from the patients within 24 hours following admission to ICU. D-lactic acid and endotoxin levels were measured by enzymatic method, serum high-sensitivity C-reactive protein (hsCRP) level by immune scatter turbidimetry. An arterial blood gas (ABG) measurement was carried out every 8 hours within the first 24 hours after admission to ICU, and average arterial blood lactate levels were calculated. Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, Sequential Organ Failure Assessment (SOFA) score of the patients within 24 hours following ICU admission were recorded. The patients with sepsis or septic shock were followed up for 28 days after admission to ICU, and divided into survival group (n=44) and death group (n=15). The patients with sepsis or septic shock were divided into two groups according to the site of infection, i. e. intra-abdominal infection group (n=37) and extra-abdominal infection group (n=22). Results: (1) In the control, sepsis, and septic shock groups, D-lactic acid [mg/L, M(P25, P75) ] were 11.68(7.49, 14.92), 19.78 (12.25, 34.85), and 32.45 (16.03, 46.95), respectively; endotoxin levels [U/L, M(P25, P75)] were 10.60(7.59, 13.39), 16.12(10.09, 20.23), and 17.31(14.09, 23.77), respectively. The levels of serum D-lactic acid and endotoxin in the patients with sepsis or septic shock were significantly higher than those in the control group (all P<0.01); while no statistically significant differences existed in these two indices between the sepsis and septic shock groups (both P>0.05). There were no statistically significant differences in serum D-lactic acid and endotoxin levels between the intra-abdominal infection group and the extra-abdominal infection group [20.07(14.70, 38.97)vs 21.65 (14.53, 56.56)mg/L; 17.23(13.38, 20.85)vs 17.17(9.93, 20.81)U/L; both P>0.05]. There were no statistically significant differences in levels of serum D-lactic acid and endotoxin between the survival group and the death group [21.65(15.11, 39.00) vs 19.78(14.41, 80.93)mg/L; 17.09(12.62, 20.42) vs 19.26(13.22, 26.27)U/L, both P>0.05]. (2) In the sepsis and septic shock patients, serum D-lactate level was significantly related to mean arterial blood lactate concentration, APACHE Ⅱ score, and SOFA score in the first 24 hours after admission to ICU (r=0.499, 0.447, 0.469, all P<0.01); serum endotoxin level was correlated with hsCRP, APACHE Ⅱ score, and SOFA score (r=0.224, 0.388, 0.393, all P<0.05). (3) Multivariate linear regression analysis showed that D-lactic acid level was independently associated with average arterial blood lactate concentration as well as with SOFA score(R2=0.34, F=19.91, P<0.01), and endotoxin was independently associated with only SOFA score(R2=0.14, F=12.68, P<0.01). Conclusions: Regardless of the site of infection, patients with sepsis or septic shock often have intestinal barrier injury, which is correlated with the severity of disease, but does not independently affect patient outcome. Tissue hypoperfusion in the early stage of sepsis may be one of the causes of intestinal barrier injury.

Abstract
In the present experiment we studied the correlation between HPV16 infection and expression of HLA-I antigen in cervical premalignant and malignant lesions (cervicitis, CIN, cervical squamous carcinomas and adenocarcinoma samples). The HPV16 E7 DNA load and the expression of HLA-I antigen in the samples were measured by real-time fluorescence quantitative polymerase chain reaction (RFQ-PCR) and immunohistochemical S-P staining, respectively. Our data indicate that HPV16 E7 load was highly and positively associated with the development of cervical lesions (Spearman's correlation coefficient r=0.848, p<0.001), the negative rate of HLA-I antigen was significantly distinguished among groups (p<0.001), and HPV16 E7 infection and downregulation of HLA-I antigen were highly correlated in cervical lesions (Pearson's correlation coefficient r=-0.487, p<0.001). HPV16 E7 may play an important role in the downregulation of HLA-I antigen in cervical lesions, which results in the immune escape of the virus and the occurrence, development, invasion and metastasis of cancer. Furthermore, quantitative PCR for HPV16 E7 may play an important role in the early detection of cervical diseases and in guiding future therapy toward prevention.

Abstract
Sows are usually restricted fed during pregnancy to maximize their reproductive efficiency, which may predispose sows to a state of hunger. However, an objective measurement of hunger status has not been established. In the present study, we examined the correlation of plasma hormones and NEFA and selected the best predictors for hunger status using pregnant gilts. Three different levels of feed intake (0.5, 1.0 and 2.0 × maintenance energy intake [0.5M, 1.0M and 2.0M, respectively]) were imposed from Day 28 to 34 of gestation to create different hunger statuses in pregnant gilts. Plasma hormones related to energy homeostasis and NEFA were analyzed to quantify their response to different levels of feed intake. A total of 18 gilts (197.53 ± 6.41 kg) were allotted to 1 of 3 dietary treatments using a completely randomized design. Results showed that BW change, ADG, and G:F from Day 28 to 34 of gestation were higher ( < 0.01) for gilts on the 2.0M feeding level than for gilts on the 0.5M feeding level. Plasma acyl ghrelin concentrations showed a relatively flat pattern during the 24-h period. Plasma acyl ghrelin and NEFA concentrations and areas under the curve (AUC) were greater ( < 0.05) in gilts on the 0.5M level of feed intake than in those on the 2.0M level of feed intake. No differences were observed among the 3 feeding levels in terms of plasma glucagon-like peptide 1 and leptin concentrations. Additionally, consumption time for 1.82 kg feed on Day 35 of gestation was longer ( < 0.01) in gilts fed the 2.0M level of feed intake from Day 28 to 34 of gestation than in those on the 0.5M level of feed intake. Simple linear regression results showed that the AUC of acyl ghrelin was the best predictor for consumption time ( = 0.82), whereas the AUC of NEFA was the best predictor for BW ( = 0.55) or backfat change ( = 0.42) from Day 28 to 34 of gestation. In conclusion, our data suggested that a relative flat pattern existed in pregnant gilts in terms of the diurnal plasma profile of acyl ghrelin and that the level of feed intake of pregnant gilts was negatively correlated with plasma concentrations of acyl ghrelin and NEFA, which, in turn, were negatively associated with feed consumption time. The AUC of acyl ghrelin and NEFA seemed to be the best predictors for hunger status of pregnant gilts.

Abstract
Some reports evaluated the association between ALOX5AP rs10507391 polymorphism and the risk of ischemic stroke in Caucasians. The results remained unknown. Thus, we did a meta-analysis to evaluate this association. Nine case-control studies with 4198 patients and 3699 controls were included in this meta-analysis. A significant association was found between ALOX5AP rs10507391 polymorphism and ischemic stroke risk in Caucasians (OR=1.18; 95%CI, 1.08-1.28; P=0.0002). ALOX5AP rs10507391 polymorphism was associated with ischemic stroke risk in Caucasians from Europe (OR=1.20; 95%CI, 1.09-1.32; P=0.0002) but not from other countries (OR=1.13; 95%CI, 0.95-1.36; P=0.17). No significant association was found between ALOX5AP rs10507391 polymorphism and ischemic stroke risk in males (OR=1.12; 95%CI, 0.91-1.39; P=0.28). Moreover, ALOX5AP rs10507391 polymorphism was not associated with cardioembolic ischemic stroke risk (OR=1.04; 95%CI, 0.73-1.48; P=0.84). In conclusion, this study found that ALOX5AP rs10507391 polymorphism was associated with ischemic stroke risk in Caucasians.

Abstract
Objective: To investigate the determinants affecting the heart rate deceleration capacity (DC) in patients with dilated cardiomyopathy (DCM). Methods: One hundred patients with DCM (DCM group) and 202 healthy subjects (control group) were respectively enrolled. Echocardiography and 24 hours electrocardiogram were performed in all subjects. DC value was compared between the two groups. Multiple regression analysis was made to evaluate the related determinants of DC ((age, sex, echocardiographic parameters including the left atrial diameter (LAD) and left ventricular ejection fraction (LVEF)). Results: (1) DC value was significantly lower in DCM group than in control group( (4.40±2.03) ms vs. (7.30±1.81) ms, P<0.01), prevalence of DC value≤4.5 ms was significantly higher in DCM group than in control group (62% vs. 6%, P<0.01). (2) DC value in the DCM group decreased in proportion to increasing LAD dimension, DC value was (5.60±2.04) ms, (4.50±2.07) ms and (3.60±1.62) ms (P<0.05) in DCM patients with LAD≤40 mm, 40 mm<LAD≤50 mm and LAD>50 mm, respectively. (3) DC value in the DCM group was negatively related to the LAD (r=-0.366, P<0.01), positively related to the LVEF (r= 0.241, P<0.01), but not related with age and sex. Multiple factors regression analysis showed that increased LAD was related to the reduced DC values independtly. Conclusion: DC value of the patients in the DCM group is decreased, which indicate the decrease of the vagus nerve tension, and increased LAD is related to the reduced DC value independtly in DCM patients.

Abstract
OBJECTIVE To investigate the effect of dexmedetomidine on the expressions of inflammatory factors, T-lymphocyte subgroups and nuclear factor kappa-B (NF-κB) in peripheral blood monocytes in the perioperative period of radical resection of gastric cancer. PATIENTS AND METHODS We selected 74 patients who were admitted to our hospital for radical resection of gastric cancer between January 2012 and October 2015. All patients were randomly divided into the dexmedetomidine group and the control group. Within 15 min before anesthesia induction, patients in the dexmedetomidine group received the intravenous injection of dexmedetomidine, while the same volume saline in the control group. During the operation, the initial dosage in the dexmedetomidine group was set as 1 μg/kg followed by 0.2 μg/kg•h intravenous injection to the end of operation. Three time points were selected: 15 min before anesthesia induction (T0), 1 h before the end of operation (T1) and 24 h after operation (T2). At these time points, we detected the levels of serum inflammatory factors using enzyme-linked immune sorbent assay (ELISA), immunoturbidimetry, and flow cytometer, respectively. RESULTS The levels of IL-1β, IL-6, TNF-α, NF-κB and CRP at T1 and T2 were significantly elevated compared with the levels at T0, and the amplitude of elevation in the control group was significantly larger than that in the dexmedetomidine group. The expression levels of T-lymphocyte subgroup in patients in both groups were decreased at T1 (compared with the levels at T0), and the decreasing extent of the ratio of CD4+ to CD8+ in the control group was significantly larger than that in the dexmedetomidine group. Meanwhile, we found that the percentages of CD3+ and CD4+ at T1 and T2 in the control group were significantly lower than those in the dexmedetomidine group. CONCLUSIONS Dexmedetomidine can effectively reduce the release of inflammatory factors in patients that received the radical resection of gastric cancer, and the anti-inflammation effect may be exerted through downregulating the expression of NF-κB. Besides, dexmedetomidine can also alleviate the reduction in subgroups of CD3+ and CD4+, thereby ameliorating the impaired immune functions.

Abstract
Schisandrin B is an active monomer of the Chinese magnolia vine (Schisandra chinensis) that can reduce transaminase activity in liver cells, inhibit lipid peroxidation, enhance antioxidant status, has protective effects in the liver and has antitumor effects. The present study investigated the potential protective effects of schisandrin B on the p53 signaling pathway in attenuating the inflammatory response, oxidative stress and apoptosis induced by traumatic spinal cord injury (TSCI) in adult rats. Behavioral examination, inclined plate test and spinal cord water content were used to evaluate the protective effect of schisandrin B in TSCI rats. The expression levels of superoxide dismutase (SOD), malondialdehyde (MDA), nuclear factor (NF)-κB subunit p65 and tumor necrosis factor (TNF)-α were examined using ELISA kits. Western blot analysis was performed to analyze the protein expression of caspase-3 and phosphorylated (p)-p53 in TSCI rats. In the present study, schisandrin B improved behavioral examination results and the maximum angle of inclined plate test, and inhibited spinal cord water content in rats with TSCI. Notably, schisandrin B reduced the activation of traumatic injury-associated pathways, including SOD, MDA, NF-κB p65 and TNF-α, in TSCI rats. In addition, schisandrin B suppressed the TSCI-induced expression of caspase-3 and p-p53 in TSCI rats. These results indicated that schisandrin B may attenuate the inflammatory response, oxidative stress and apoptosis in TSCI rats by inhibiting the p53 signaling pathway in adult rats.

Abstract
Objective: To investigate the clinical characteristics, pathogenesis and surgical strategy for the chronic subdural hematoma associated with arachnoid cyst (AC). Method: Ten patients of chronic subdural hematoma associated with AC were retrospectively enrolled from the Neurosurgery Department of Tianjin Medical University General Hospital from January 2012 to September 2015, with a mean age of 27.5±5.6 years (range, 18-37 years). All patients simply performed a burr hole drainage of hematoma and left the AC intact, then followed up for 12 to 18 months after discharge respectively. Results: In this study, the AC in 8 of 10 cases occurs in the middle cranial fossa, and the other 2 cases root in the cerebral hemisphere.The AC of 10 patients all locate near the hematoma cavity.Nine patients had a full recovery, and only one patient had a recurrent subdural hematoma with a secondary operation, then recovery in 3 months postoperation.All patients lived completely free of neurological symptom and showed no recurrence in the follow-up period with a Barthel index more than 90. Conclusion: Simply burr hole drainage of hematoma and leave intact AC achieves satisfied outcome and provides a reliable therapy strategy for chronic subdural hematoma associated with arachnoid cyst.

Abstract
OBJECTIVE To investigate the association between serum aluminium level and methylation of the promoter region of amyloid precursor protein (APP)gene in workers engaged in aluminium electrolysis. METHODS In 2012, 366 electrolysis workers in an aluminium factory were enrolled as exposure group (working years >10 and age >40 years)and divided into low-exposure group and high-exposure group based on the median serum aluminium level. Meanwhile, 102 workers in a cement plant not exposed to aluminium were enrolled as control group. Graphite furnace atomic absorption spectrometry was used to measure serum aluminium level, methylation specific PCR was used to measure the methylation rate of the promoter region of APP gene, and ELI-SA was used to measure the protein expression of APP in lymphocytes in peripheral blood. RESULTS The exposure group had a significantly higher serum aluminium level than the control group (45.07 μg/L vs 30.51 μg/L, P< 0.01). The exposure group had a significantly lower methylation rate of the promoter region of APP gene than the control group (18.85% vs 25.49%, P=0.025), and the high-exposure group had a significantly lower methylation rate of the promoter region of APP gene than the low-exposure group (15.84% vs 21.85%, P<0.05). The exposure group had a significantly higher protein expression of APP in lymphocytes in peripheral blood than the control group (66.73 ng/ml vs 54.17 ng/ml, P<0.05); compared with the low-exposure group (65.39 ng/ml), the high-exposure group showed an increase in the protein expression of APP in lymphocytes in peripheral blood (67.22 ng/ml), but there was no significant difference between these two groups (P>0.05). The multivariate logistic regression analysis showed that with reference to the control group, low aluminium exposure (OR=1.86, 95% CI 1.67~3.52)and high aluminium exposure (OR=2.98, 95% CI 1.97~4.15)were risk factors for a reduced methylation rate of the promoter region of APP gene. CONCLUSION Reduced methylation of the promoter region of APP gene may be associated with increased serum aluminium level, and downregulated methylation of the promoter region of APP gene may accelerate APP gene transcription.

Abstract
OBJECTIVE To compare the curative effects of two unilateral puncturation percutaneous vertebroplasty (PVP) for the pain caused by multiple-level osteoporotic vertebral body compression fractures (OVCF) in senile patients. PATIENTS AND METHODS From June 2008 to November 2014, eighty-nine cases suffering from fresh multiple-level OVCF were randomly divided into experimental group (n=51) and control group (n=38). Patients underwent PVP guided by C-arm fluoroscopy in the prone position. We monitored and recorded the visual analgesic scale (VAS) at pre-operation and 2 days post-operation, operation time, exposure duration, bone cement injection amount and extraosseous cement leakages. RESULTS PVP procedures were successful in both groups without serious complications. The VAS scores in both two groups at 2 days post-operation were significantly lower than VAS scores at pre-operation (p<0.05). The operation time and exposure duration in the observational group were significantly lower than those in the control group (p<0.05). However, bone cement injection amount and extraosseous cement leakages in the observing group were similar to those in control (p>0.05). CONCLUSIONS The curative effects of two unilateral puncturation PVPs were satisfactory. However, puncturation method had lower operation time and lower X-ray exposure dose. We concluded that puncturation method was a suitable method to be considered for clinical application.

Abstract
The present study investigated the effects of different feeding levels during 3 short periods of gestation on gilt and litter performance, apparent total tract digestibility (ATTD) of energy and nutrients, and energy homeostasis in gilts. A total of 18 gilts were allotted to 1 of 3 dietary treatments using a completely randomized design. All gilts were fed 1 common corn-soybean meal-based diet with the amount of 1.0 × maintenance energy intake (100 × BW (BW) kcal ME/d) throughout gestation except 3 periods of 7 d when dietary treatments were imposed on d 27, d 55, and d 83 of gestation. During the 3 short periods, gilts were fed 1 of 3 different feeding levels: 0.5, 1.0, and 2.0 × maintenance energy level (0.5M, 1.0M, and 2.0M, respectively). Results showed that gilts on 2.0M feeding level had higher ( < 0.05) weight gain from d 27 to 109 of gestation (37.05 vs. 15.34 kg) and greater ( < 0.05) BW change, average daily gain, and gain to feed ratio during gestation periods 1 (d 27-34) and 3 (d 83-90) when compared with gilts on 0.5M feeding level. No differences ( > 0.10) in litter performance were observed among the 3 feeding levels. Additionally, the slopes of BW change in response to feeding levels in period 1 were 4.32 kg/0.5M change from 0.5M to 1.0M feeding level and 3.72 kg/0.5M change from 1.0M to 2.0M feeding level, respectively. There were quadratic ( < 0.05) effects of feeding levels on ATTD of dry matter and gross energy during periods 1 and 2 (d 55-62). Furthermore, fasting plasma concentrations of acyl ghrelin and nonesterified fatty acid (NEFA) in period 1 were greater ( < 0.01) in gilts on 0.5M feeding level than those on 2.0M feeding level. In conclusion, increasing feeding levels during 3 short periods increased primiparous sow performance during these short periods but did not affect litter performance. ATTD of energy and nutrients, and BW change efficiency were maximized for gilts on 1.0 M feeding level. The data also indicated that sows on the lowest feeding level were exposed to negative energy balance as evidenced by the higher plasma acyl ghrelin and NEFA concentrations.

Abstract
miRNAs are small non-coding regulatory RNAs that play key roles in diverse biological processes. In this study, we used the Solexa sequencing technique to profile miRNAs in breeder cock testes to illustrate their functions. A total of 663 co-expressed miRNAs and 3,180 co-expressed piRNAs were detected in three libraries. Based on Mir-X™ miRNA qRT-PCR, three miRNAs representing low, medium and high expression levels according to the sequencing results were selected randomly to validate the miRNAs' expression profiles. Results suggested that the miRNA expression profiles data could represent actual miRNA expression levels. Moreover, target genes prediction of the co-expressed miRNAs and further Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses were performed, which revealed that some candidate miRNAs were involved in the regulation of the spermatogenesis process, spermatozoa function and testicular metabolism. In conclusion, we provided a useful resource for further elucidation of the miRNAs' regulatory role in spermatogenesis, contributing to a preliminary database for functional and molecular mechanistic studies in testicular metabolism, spermatogenesis and other testes functions.

Abstract
OBJECTIVE To investigate long noncoding RNA PVT1 expression in the serum of cervical cancer patients, and to evaluate serum PVT1 level as a diagnostic biomarker for cervical cancer. PATIENTS AND METHODS Eighty-eight cervical cancer patients, 64 cervical intraepithelial neoplasia patients, 25 breast cancer patients, 25 ovarian cancer patients, and 111 healthy control subjects were enrolled into this study. PVT1 serum level in these participants and PVT1 expression in 20 pairs of cervical cancer tissues and adjacent paired normal tissues was measured by quantitative reverse transcription-polymerase chain reaction. The diagnostic values of serum PVT1 were evaluated by receiver operating characteristic curves analysis. RESULTS Serum PVT1 level is significantly increased in cervical cancer patients and correlated with tumor size, clinical stage, and lymph node metastasis of cervical cancer. Serum PVT1 could accurately discriminate cervical cancer patients from cervical intraepithelial neoplasia patients and healthy control subjects, and also discriminate early stage cervical cancer patients from healthy control subjects. But serum PVT1 level is not changed in breast cancer and ovarian cancer patients. Furthermore, serum PVT1 level is positively correlated with tissue PVT1 expression, and could indicate cervical cancer dynamics. CONCLUSIONS Long noncoding RNA PVT1 may be a novel noninvasive biomarker for early diagnosis of cervical cancer.

Abstract
OBJECTIVE We evaluated uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP) levels in different clinical types of acute coronary syndromes (ACS) and in relationship with the severity of coronary artery lesions. Furthermore, we explored its clinical significance. PATIENTS AND METHODS From June 2013 to January 2015, we studied patients in their first onset of symptoms and hospitalization for coronary angiography. According to coronary angiography results, we divided patients into two groups: 93 patients with ACS and 30 patients with normal coronary arteries as the control group. ACS patients were divided further into three subgroups: patients with ST-segment elevation myocardial infarction (STEMI) (n=34); patients with non-ST segment elevation myocardial infarction (NSTEMI) (n=29); and patients with unstable angina (n=30). According to their Gensini scores, patients were divided into mild, moderate and severe groups. We compared UA and hs-CRP levels and the relationship with Gensini scores between different groups. RESULTS UA and hs-CRP levels in the ACS group were higher than those in the control group (p < 0.05). UA and hs-CRP levels in the STEMI group were higher than those in the NSTEMI, unstable angina and control groups (p < 0.05). UA and hs-CRP levels in the NSTEMI patients were higher than those in the unstable angina and control groups (p < 0.05). UA and hs-CRP levels in the unstable angina patients were higher than those in the control group (p < 0.05). hs-CRP levels in the STEMI patients were higher than the other groups (p < 0.05). hs-CRP levels in the NSTEMI patients were higher than the unstable angina and the control groups (p < 0.05) while hs-CRP levels in the unstable angina patients were higher than the control group (p < 0.05). Additionally, according to the Gensini score group, we discovered that ACS patients in the severe group had higher hs-CRP levels than the other three groups (p < 0.05) while the moderate group had higher levels than the other two groups (p < 0.05). The mild group had higher levels than the control group (p < 0.05). Correlation analysis suggested that UA levels and Gensini scores had a positive correlation (p < 0.05). hs-CRP levels and Gensini scores also showed a positive correlation (p < 0.05). CONCLUSIONS UA and hs-CRP levels should be considered as factors to use in the risk stratification in ACS patients.
