Abstract
Using the fusion-evaporation reaction ^{106}Cd(^{58}Ni,4n)^{160}Os and the gas-filled recoil separator SHANS, two new isotopes _{76}^{160}Os and _{74}^{156}W have been identified. The α decay of ^{160}Os, measured with an α-particle energy of 7080(26) keV and a half-life of 201_{-37}^{+58} μs, is assigned to originate from the ground state. The daughter nucleus ^{156}W is a β^{+} emitter with a half-life of 291_{-61}^{+86} ms. The newly measured α-decay data allow us to derive α-decay reduced widths (δ^{2}) for the N=84 isotones up to osmium (Z=76), which are found to decrease with increasing atomic number above Z=68. The reduction of δ^{2} is interpreted as evidence for the strengthening of the N=82 shell closure toward the proton drip line, supported by the increase of the neutron-shell gaps predicted in theoretical models.

Abstract
Objective: To explore the effects of preoperative hysteroscopic guided biopsy and segmental diagnosis and curettage on the risk of abdominal dissemination and prognosis of non-endometrioid carcinoma. Methods: The clinical and pathological data of 97 patients who underwent surgical treatment and were pathologically confirmed as non-endometrioid carcinoma (including serous carcinoma, clear cell carcinoma, mixed adenocarcinoma, and undifferentiated carcinoma, etc.) from October 2008 to December 2021 in Peking University People's Hospital, were collected for retrospective analysis. According to preoperative diagnostic methods, they were divided into hysteroscopic group (n=44) and non-hysteroscopic group (n=53). The impact of hysteroscopy examination on peritoneal cytology and prognosis was analyzed. Results: (1) There were no statistical differences in age, body mass index, tumor size, pathological characteristics, and treatment methods between the hysteroscopic group and the non-hysteroscopic group (all P>0.05), but the proportion of stage Ⅰ-Ⅱ patients in the hysteroscopic group was significantly higher than that in the non-hysteroscopic group [68% (30/44) vs 47% (25/53); χ2=4.32, P=0.038]. (2) Among 97 patients, 25 (26%, 25/97) of them were cytologically positive for ascites. The hysteroscopic group had a lower positive rate of peritoneal cytology than that in the non-hysteroscopy group, which was significantly different [11% (5/44) vs 38% (20/53); χ2=8.74, P=0.003]. Stratification according to surgical and pathological stages showed that the positive rate of peritoneal cytology in the hysteroscopic group (3%, 1/30) was lower than that in the non-hysteroscopic group (12%, 3/25) in the 55 patients with stage Ⅰ-Ⅱ, and that in the hysteroscopic group (4/14) was also lower than that in the non-hysteroscopic group (61%, 17/28) in the 42 patients with stage Ⅲ-Ⅳ. There were no significant differences (all P>0.05). (3) The 5-year disease-free survival (DFS) rate of the hysteroscopic group and the non-hysteroscopic group were respectively 72.7% and 60.4%, and there was no significant difference between the two groups (P=0.186). After stratification according to staging, the 5-year DFS rate were respectively 90.0% and 72.0% (P=0.051) between the hysteroscopic and non-hysteroscopic groups of patients in stage Ⅰ-Ⅱ, and 35.7% and 50.0% (P=0.218) between the hysteroscopic and non-hysteroscopic groups of patients in stage Ⅲ-Ⅳ, in which there were not statistically significant differences. The 5-year overall survival (OS) rate were respectively 86.4% and 81.1% between the hysteroscopic group and the non-hysteroscopic group, with no significant difference between the two groups (P=0.388). The 5-year OS rate were respectively 93.3% and 96.0% in the hysteroscopic group and non-hysteroscopic group for patients with stage Ⅰ-Ⅱ(P=0.872), and 71.4% and 67.9% in the hysteroscopic group and non-hysteroscopic group in patients with stage Ⅲ-Ⅳ (P=0.999), with no statistical significance. Conclusions: Diagnostic hysteroscopy do not increase the rate of positive peritoneal cytology result at the time of surgery in this cohort, and no significant correlation between preoperative hysteroscopy examination and poor prognosis of non-endometrioid carcinoma is observed. Therefore, preoperative hysteroscopic guided biopsy and segmental diagnosis and curettage in non-endometrioid carcinoma maybe safe.

Abstract
Objective: To investigate the relationships between molecular types of the cancer genome atlas (TCGA) of patients with endometrial carcinoma (EC) and lymph node metastasis and other clinicopathological features. Methods: The clinical pathological information of 295 patients with EC who underwent initial inpatient surgical treatment and accepted the detection of the molecular types of TCGA with next-generation sequencing technology at Peking University People's Hospital were collected during April 2016 and May 2022. The TCGA molecular typing of EC was divided into four types: POLE-ultramutated (15 cases), high microsatellite instability (MSI-H; 50 cases), copy-number low (CNL; 175 cases), and copy-number high (CNH; 55 cases). The differences of clinical pathological features among different molecular types and the risk factors of lymph node metastasis were analyzed retrospectively. Results: Among 295 patients with EC, the average age was (56.9±0.6) years. (1) There was a statistically significant difference in lymph node metastasis (0, 8.0%, 10.3% and 25.5%) among the four molecular types (χ2=12.524, P=0.006). There were significant differences in age, stage, pathological type, grade (only endometrioid carcinoma), myometrium invasion, lymphatic vascular space infiltration, and estrogen receptor among the EC patients of four molecular types (all P<0.05). Among them, while in the patients with CNH type, the pathological grade was G3, the pathological type was non-endometrioid carcinoma, and the proportion of myographic infiltration depth ≥1/2 were higher (all P<0.05). (2) Univariate analysis suggested that pathological type, grade, myometrium infiltration depth, cervical interstitial infiltration, lymphatic vascular space infiltration, and progesterone receptor were all factors which significantly influence lymph node metastasis (all P<0.01); multivariate analysis suggested that the lymphatic vascular space infiltration was an independent risk factor for lymph node metastasis (OR=5.884, 95%CI: 1.633-21.211; P=0.007). (3) The factors related to lymph node metastasis were different in patients with different molecular types. In the patients with MSI-H, the non-endometrioid carcinoma of pathological type was independent risk factor for lymph node metastasis (OR=29.010, 95%CI: 2.067-407.173; P=0.012). In the patients with CNL, myometrium infiltration depth≥1/2 (OR=4.995, 95%CI: 1.225-20.376; P=0.025), lymphatic vascular space infiltration (OR=14.577, 95%CI: 3.603-58.968; P<0.001) were the independent risk factors for lymph node metastasis. While in the CNH type patients pathological type of non-endometrioid carcinoma (OR=7.451, 95%CI: 1.127-49.281; P=0.037), cervical interstitial infiltration (OR=22.938, 95%CI: 1.207-436.012; P=0.037), lymphatic vascular space infiltration (OR=9.404, 95%CI: 1.609-54.969; P=0.013), were the independent risk factors for lymph node metastasis. Conclusions: POLE-ultramutated EC patients have the lowest risk of lymph node metastasis, and CNH patients have the highest risk of lymph node metastasis. The risk factors of lymph node metastasis of different molecular types are different. According to preoperative pathological and imaging data, lymph node metastasis is more likely to occur in patients with non-endometrioid carcinoma in MSI-H and CNH type patients, and lymph node metastasis is more likely to occur in patients with myometrium infiltration depth ≥1/2 in CNL type patients.

Abstract
Objective: To compare the prognosis and perioperative situation of patients with stage Ⅱ endometrial cancer (EC) between radical hysterectomy/modified radical hysterectomy (RH/mRH) and simple hysterectomy (SH). Methods: A total of 47 patients diagnosed EC with stage Ⅱ [International Federation of Gynecology and Obstetrics (FIGO) 2009] by postoperative pathology, from January 2006 to January 2021 in Peking University People's Hospital, were analyzed retrospectively. The patients were (54.4±10.7) years old, and the median follow-up time was 65 months (ranged 9-138 months). They were divided into RH/mRH group (n=14) and SH group (n=33) according to the scope of operation. Then the prognosis of patients between the groups were compared, and the independent prognostic factors of stage Ⅱ EC were explored. Results: (1) The proportions of patients with hypertension in RH/mRH group and SH group were 2/14 and 45% (15/33), the amounts of intraoperative blood loss were (702±392) and (438±298) ml, and the incidence of postoperative complications were 7/14 and 15% (5/33), respectively. There were significant differences (all P<0.05). (2) The median follow-up time of RH/mRH group and SH group were 72 vs 62 months, respectively (P=0.515). According to Kaplan-Meier analysis and log-rank method, the results showed that there were no significant difference in 5-year progression-free survival (PFS) rate (94.3% vs 84.0%; P=0.501), and 5-year overall survival rate (92.3% vs 92.9%; P=0.957) between the two groups. Cox survival analysis indicated that age, pathological type, serum cancer antigen 125 (CA125), and estrogen receptor (ER) status were associated with 5-year PFS rate (all P<0.05). But the scope of hysterectomy (RH/mRH and SH) did not affect the 5-year PFS rate of stage Ⅱ EC patients (P=0.508). And level of serum CA125 and ER status were independent prognostic factors for 5-year PFS rate (all P<0.05). Conclusions: This study could not find any survival benefit from RH/mRH for stage Ⅱ EC, but increases the incidence of postoperative complications. Therefore, the necessity of extending the scope of hysterectomy is questionable.

Methods: A retrospective study was performed on 158 neonates born to mothers infected with SARS-CoV-2 Omicron variant admitted to the isolation ward of Children's Hospital of Fudan University from March 15th, 2022 to May 30th, 2022. The postnatal infection control measures for these neonates, and their clinical characteristics and short-term outcomes were analyzed. They were divided into maternal symptomatic group and maternal asymptomatic group according to whether their mothers had SARS-CoV-2 symptoms. The clinical outcomes were compared between the 2 groups using Rank sum test and Chi-square test. Results: All neonates were under strict infection control measures at birth and after birth. Of the 158 neonates, 75 (47.5%) were male. The gestational age was (38+3±1+3) weeks and the birth weight was (3 201±463)g. Of the neonates included, ten were preterm (6.3%) and the minimum gestational age was 30+1 weeks. Six neonates (3.8%) had respiratory difficulty and 4 of them were premature and required mechanical ventilation. All 158 neonates were tested negative for SARS-COV-2 nucleic acid by daily nasal swabs for the first 7 days. A total of 156 mothers (2 cases of twin pregnancy) infected with SARS-CoV-2 Omicron variant, the time from confirmed SARS-CoV-2 infection to delivery was 7 (3, 12) days. Among them, 88 cases (56.4%) showed clinical symptoms, but none needed intensive care treatment. The peripheral white blood cell count of the neonates in maternal symptomatic group was significantly higher than that in maternal symptomatic group (23.0 (18.7, 28.0) × 109 vs. 19.6 (15.4, 36.6) × 109/L, Z=2.44, P<0.05). Conclusions: Neonates of mothers infected with SARS-CoV-2 Omicron variant during third trimester have benign short-term outcomes, without intrauterine infection through vertical transmission. Strict infection control measures at birth and after birth can effectively protect these neonates from SARS-CoV-2 infection.

Abstract
Objective: To investigate the diagnostic value of rapid antigen test based on colloidal gold immunochromatographic assay for the detection of SARS-CoV-2 infection in symptomatic patients. Methods: From May 20 to June 5 2022, 76 hospitalized children and their 55 accompanying family members with confirmed SARS-CoV-2 infection in the COVID-19 isolation unit of the Children's Hospital of Fudan University (designated referral hospital for SARS-CoV-2 infection in Shanghai) enrolled. Their nasopharyngeal swab specimens were consecutively collected. The samples were tested for SARS-CoV-2 nucleic acid by real-time quantitative. SARS-CoV-2 antigen was tested by immunochromatography. The correlation between the antigen detection results and the change of the cycle threshold (Ct) values were evaluated, as well as the sensitivity and specificity of SARS-CoV-2 antigen detection at different periods after the onset of the disease. Kappa consistency test was conducted to investigate the consistency between the 2 diagnostic methods. Results: Of the enrolled SARS-CoV-2 symptomatic infections, 76 were children, including 41 males and 35 females, with an age of 5 (2, 9) years; 55 were accompanying families, including 8 males and 47 females, with an age of 38 (32, 41) years. All 478 samples were simultaneously tested for SARS-CoV-2 antigen and nucleic acid. In any period from disease onset to negative conversion of viral nucleic acid, the overall sensitivity of the rapid antigen test was 48.2% (119/247), the specificity was 98.3% (227/231), and antigen test and nucleic acid test showed moderate consistency (κ=0.46, P<0.05). The sensitivity of antigen test was 100% (82/82) when the Ct value was ≤25. And the sensitivity of antigen test was 8/10, 4/15 and 8.3% (3/36) when the Ct value was 26, 30 and 35, respectively. All antigen tests were negative when Ct value was >35. During the period of 1-2 days, 3-5 days, 6-7 days, 8-10 days and >10 days after onset, the sensitivity and specificity of SARS-CoV-2 antigen test were 5/8 and 5/5, 90.2% (37/41) and 5/5, 88.9% (24/27) and 2/5, 45.0% (36/80) and 94.1% (32/34), 18.7% (17/91) and 98.9% (183/185) respectively. The Ct values of nasopharyngeal swabs were<26 during 2 to 7 days after onset, 28.7±5.0 on day 8, 34.5±2.9 on day 13 and > 35 after 14 days, respectively. Conclusion: SARS-CoV-2 antigen test in the patients with SARS-CoV-2 infection shows acceptable sensitivity and specificity within 7 days after onset of disease, and the sensitivity was positively correlated with viral load and negatively correlated with onset time.

Abstract
Objective: To review the application for funding of ophthalmologic projects from the National Natural Science Foundation of China (NSFC) and the current research progress, and to provide reference for the promotion of basic eye research in China. Methods: The NSFC application and funding information of ophthalmology-related projects from 2010 to 2021 were collected as a database for further analysis. The main categories of the analysis included the number of application and funding, the funding ratio, the research directions and the funded organizations. Results: During the 12 years, 13 267 applications were received in the field of ophthalmology, with an increase of 157.21% (1 025/652) in 2021 compared with 2010, and the number of applications for the Youth Foundation grew significantly. There were 2 221 funded projects, with an increase of 81.51% (97/119) in 2021 compared with 2010. After 2017, the number of funded projects was basically around 200 per year, with a funding rate of 16.74%(2 221/13 267). The funding amount was 1 026.9 million yuan in total, with an average of 462 400 yuan. Sun Yat-sen University (1 060 applied and 265 funded projects), Fudan University (759 applied and 186 funded projects), Shanghai Jiaotong University (820 applied and 178 funded projects), Wenzhou Medical University (625 applied and 113 funded projects) and Capital Medical University (538 applied and 95 funded projects) were the top five institutions in terms of the number of application and funding. Conclusions: From 2010 to 2021, the application number of ophthalmology projects increased rapidly, while the number of funded projects increased slowly, and the funding ratio decreased year by year. With the support of NSFC, the basic research of ophthalmology in China has made great progress. However, we still need to find and solve problems to promote the sustainable advance of ophthalmology.

Abstract
Objective: To investigate the related factors associated with the structure of the gut microbial community in HIV infection/AIDS cases (HIV/AIDS) in Henan province. Methods: The convenience sampling method was used to select 122 cases who were receiving Antiviral Treatment (ART) or ART-naive in Henan. Whole blood and stool specimens were collected. Genomic DNA of stool samples was extracted, and the V3-V4 hypervariable regions of the 16S rRNA gene were sequenced using Illumina NovaSeq 6000 high-throughput sequencing system. The analysis was performed mainly at the genus level, and the 30 genera with the highest abundance were selected as a measure of the gut microbial community structure. The correlation between community structure and related factors was analyzed using redundancy analysis and Envfit function. Results: 122 cases were finally completed sequencing and analysis, the average BMI was (23.62±2.78) kg/m2 and the average age was (47±13) years. Among them, male accounted for 66.39% (81/122), and heterosexual transmission route constituted the largest ratio, accounting for 51.64% (63/122). 36 cases were treatment naive (29.51%, 36/122). The top five dominant genera of the total population (122 cases) were Prevotella, Roseburia, Megamonas, Bacteroides and Faecalibacterium and the top five dominant genera of the ART population (86 cases) were Prevotella, Megamonas, Bacteroides, Roseburia and Faecalibacterium. The top five dominant genera of the ART-naive population (36 cases) appeared as Prevotella, Faecalibacterium, Roseburia, Bacteroides and Megamonas. In the total population, ART (P<0.001) was the most significant factors of community structure. Other significant factors were: duration of diagnosis (P=0.009), viral load (P=0.022) and anti-HCV (P=0.018). ART was positively correlated with Megamonas and negatively correlated with Prevotella, Roseburia and Faecalibacterium, while the other three factors of duration of diagnosis, viral load and anti-HCV were positively correlated with Prevotella, Roseburia and Faecalibacterium and negatively correlated with Megamonas. In the ART-naive population, duration of diagnosis (P=0.003) were the factors significantly associated with community structure. Duration of diagnosis was positively correlated with Roseburia, Faecalibacterium, Megamonas and Prevotella and negatively correlated with Bacteroides. Conclusion: ART and duration of diagnosis were factors significantly associated with gut microbial community structure and had a significant impact on multiple high-abundance genera.

Abstract
Three cases of synchronous primary bilateral macronodular adrenal hyperplasia(PBMAH) and renal cell carcinoma (RCC) in the Department of Urology of Peking Union Medical College Hospital were retrospectively reviewed. The clinical features, imaging features, treatment methods and pathological features of these patients were analyzed. It was found that the genetic relationship between synchronous PBMAH and RCC needs further research. And RCC is easy to be misdiagnosed. We should pay high attention to imaging features to find out whether there are lesions in bilateral kidneys when we deal with bilateral adrenal lesions. Laparoscopic approach is recommended for PBMAH and RCC. Total or partial nephrectomy should be performed according the tumor size and location of the renal mass. Patients with PBMAH should be closely followed up after bilateral adrenalectomy to avoid delay in diagnosis or treatment of RCC.

Abstract
Objective: Establishment of a new model of human primary colon cancer transplantation tumor in normal immune mice and to provide a reliable experimental animal model for studying the pathogenesis of colon cancer under normal immunity. Methods: Human colon cancer cells come from colon cancer patients who underwent surgery in the Affiliated Hospital of Jining Medical College in 2017. The mice in the cell control group were inoculated with phosphate buffered solution (PBS) containing colon cancer cells, the microcarrier control group was inoculated with PBS containing microcarrier 6, and the cell-microcarrier complex group was inoculated with the PBS containing colon cancer cell-microcarrier complex. The cells of each group were inoculated under the skin of the right axilla of mice by subcutaneous injection, and the time, size, tumor formation rate and pathological changes under microscope were recorded. The transplanted tumor tissue was immunohistochemically stained with the EnVisiion two-step method, and the tumor formation rate of the transplanted tumor was judged according to the proportion of positive cells in the visual field. The polymerase chain reaction (PCR) method was used to detect the expression of human-specific Alu sequence in mice tumor tissue. Results: After inoculation with tumor cells, the mice in the cell control group and the microcarrier control group did not die and did not form tumors; the mice in the cell-microcarrier complex group had palpable subcutaneous tumors in the right axillary subcutaneously on the 5th to 7th days after inoculation, and tumor formation rate is 67% (10/15), and the tumor volume can reach about 500 mm(3) 2 to 3 weeks after vaccination. The immunohistochemistry results showed that CK20, CDX-2 and carcinoembryonic antigen were all positively expressed. The PCR results showed that the expression of human-specific Alu sequence can be detected in the transplanted tumor tissue of tumor-bearing mice. Conclusion: Human primary colon cancer cells used microcarrier 6 as a carrier to form tumors in normal immunized mice, and successfully established a new model of human colon cancer transplantation tumor in normal immune mice.

Abstract
Objectives: To examine the prognosis factors of recurrence of esophageal carcinoma within 6 months after neoadjuvant therapy followd by surgery. Methods: The clinical data of 187 patients with esophageal squamous cell carcinoma who underwent neoadjuvant therapy followed by curative esophagectomy between January 2018 and April 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital were analyzed retrospectively. There were 160 males and 27 females, aging (63.0±7.1) years (range:43 to 76 years). The t test, χ2 test and rank-sum test were used for univariate analysis of the prognosis factors for recurrence within 6 months postoperative, while the Logistic regression was used for multivariate analysis. Results: There were 30 patients (16.0%) developed recurrence within 6 months after operation, including local recurrence in 1 case, regional recurrence in 11 cases, hematogenous recurrence in 13 cases, and combined recurrence in 5 cases. Univariate analysis suggested that there was a significant difference in T staging of tumor before neoadjuvant therapy (cT), tumor regression grade, circumferential resection margin, pathological T stage (ypT) and pathological N stage (ypN) between the recurrence patients and non-recurrence patients (all P<0.05). Logistic regression analysis suggested that the cT3-4 (OR=2.701, 95%CI: 1.161 to 6.329, P=0.021) and ypN(+)(OR=1.654, 95%CI: 1.045 to 2.591, P=0.032) were the independent prognosis factors for recurrence within 6 months. Conclusion: The combination of neoadjuvant therapy and surgery is not effective in reducing early postoperative recurrence in patients who have invaded the epineurium before treatment, and still have positive lymph nodes after neoadjuvant therapy.

Abstract
Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

Abstract
Objective: To examine the preliminary clinical efficacy of Chinese magnetic sphincter augmentation (MSA) in the treatment of gastroesophageal reflux disease (GERD). Methods: According to the enrollment criteria for the MSA developed by ShengJieKang Co. and Shanghai Chest Hospital (SS-MSA) clinical trial, a total of 19 GERD patients were treated with SS-MSA from August 2018 to January 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiao Tong University. The majority of registered cases were male patients with age of (32.2±7.3) years (range: 22 to 50 years), height of (170.7±6.2) cm (range: 160 to 179 cm) and weight of (65.2±10.3) kg (range: 47.5 to 90.0 kg). SS-MSA was implanted via laparoscopy. The major evaluation indexs of postoperative efficacy were the total time of acid exposure within 24 hours and the total number of reflux. Secondary efficacy indicators included: (1) evaluation of the average daily dose of proton pump inhibitor medications; (2) the score of GERD health related quality of life questionnaire (GERD-Q) before and after MSA implantation. Paired design t-test was used to evaluate the efficacy of the SS-MSA. Results: A total of 19 patients underwent SS-MSA surgery successfully. The history of the GERD were 19 (54) months (M(Q(R))). The operation time was 63 (22) minutes and the in-hospital stay was 3 (2) days. No obvious surgical complications occurred. Postoperative adverse events included 14 cases with mild to moderate dysphagia exited after surgery, gradually eased within 1 to 3 months, 1 case with the removal of the device after 1 month of severe swallowing difficulties, 1 case of diarrhea. No corrosion, perforation, displacement occurred. The GERD-Q score (11.0(4.5) vs. 6(1.0), t=4.274, P=0.013), 24-hour acid exposure time (6.2(4.8)% vs. 0.1(0.9)%, t=5.814, P=0.004), and Demeester score (23.72(16.20) vs. 0.96(3.10), t=6.678, P=0.003) were significantly decreased 1 year after surgery(n=5). Proton pump inhibitor reuse rates were 6/18, 5/15, 3/10, and 1/5 in 1, 3, 6 and 12 months after the operation, respectively. Conclusions: SS-MSA implantation is feasible and safe with short hospital stay and rare perioperative complications. The preliminary results is good after 1 year follow-up. It could be expected to be an ideal substitutive for future GERD treatment.

Abstract
Objective: To access the effectiveness and safety of the intrauterine balloon tamponade verse gauze packing combined with temporary abdominal aortic balloon occlusion in the management of placenta accreta spectrum (PAS). Methods: This was an open-label, randomized controlled trial conducted in Nanjing Drum Tower Hospital. The patients suspected with PAS for uterine preservation surgery under the multidisciplinary team care were recruited between Aug 2015 and Jan 2018. When bleeding could not be achieved after fetus delivered, and a temporary abdominal aortic balloon occlusion and the compression sutures as needed, the women were randomly allocated 1∶1 into balloon tamponade (n=81) or gauze packing (n=80) group. The primary outcome was successful bleeding arrests by avoiding second line surgeries. The secondary outcomes included the volume of blood loss during and after cesarean section, the rate of PPH, incidence and amount of blood transfusion, hysterectomy, postpartum pain, ICU admission, need for re-laparotomy, and the length of hospital stay, readmission, and interventional radiology complications. Results: All the women [100% (81/81)] in the balloon group were obtained hemostasis without further intervention, significantly higher than 88% (70/80) in the gauze group (P=0.001). Before uterine tamponade, blood loss were 820 ml (620-1 230) ml and 850 ml (605-1 442) ml, while placenta bed were sutured in 96%(78/81, 77/80) respectively (P>0.05).The proportion of blood loss≥1 000 ml was higher in the gauze group than that in the balloon group (P=0.006). Maternal adverse events involving total blood loss, puerperal morbidity and postpartum pain occurred more frequently in the gauze group (P<0.05). The following outcome showed no statistically significant difference between the two groups: the vascular occlusion time, the dose of radiation, and interventional radiology complication (P>0.05). The median volume infused into the lower and upper balloons is 70 ml (50-100 ml) and 180 ml (100-240 ml). Conclusions: Incrauterine balloon tamponade is as effective as gauze packing in hemostasis following the placenta delivery in PAS. Compared with gauze packing, the uterine balloon tamponade is more effective.

Abstract
Objective: To study the strategy of endovascular treatment for patients with the risks of internal carotid artery (ICA) rupture and bleeding during the treatment of nasopharyngeal carcinoma (NPC) based on American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grade of collateral circulation. Methods: A total of 56 patients (45 males and 11 females, aged from 28 to 76 years old) diagnosed with nasopharyngeal carcinoma and admitted to the Department of Neurosurgery, the Third Affiliated Hospital of Southern Medical University from July 2018 to January 2020 were retrospectively analyzed. There were 15 cases of ASITN/SIR grade 4, 24 cases of ASITN/SIR grade 3, 5 cases of ASITN/SIR grade 2, 5 cases of ASITN/SIR grade 1, and 7 cases of ASITN/SIR grade 0. The events of stroke and death were analyzed statistically. Results: ALL patients with ASITN/SIR grade 4 or 3 and some of patients with ASITN/SIR grades 2-0 passed balloon occlusion test and electrophysiological monitoring. ICA pseudoaneurysm was found in 35 patients, and one-stage ICA embolization was performed in 29 patients after evaluation. Among them, 8 cases of ASITN/SIR grade 4 and 10 cases of ASITN/SIR grade 3 with obvious posterior circulation compensation obtained successful one-stage ICA embolization without cerebral ischemia; cerebral ischemic events occurred in 5 (55.6%) of 9 patients with ASITN/SIR grade 3 and in 1(50.0%) of 2 patients with ASITN/SIR grade 2. The total incidence of ischemic events was 20.7% (6/29) and 1 case was disabled (1/29, 3.4%). Among patients with ASITN/SIR 3, there were statistically significant differences in stroke event rate between patients with obvious posterior circulation compensation and patients with slight or without posterior circulation compensation (0/10 vs. 5/9, χ(2)=4.95, P=0.026). Follow-up time was 10.1±7.8 months, and 46 patients were survival (46/56, 82.1%) and 10 patients died (10/56, 17.9%) with a mean survival time of 2.6±1.4 months. Conclusions: For NPC patients with ICA invasion, ASITN/SIR based on DSA can simplify the assessment process of cerebral blood flow compensation. ICA can be embolized directly in patients with ASITN/SIR 4 or 3 with obvious posterior communicating compensation.

Abstract
Immune checkpoint inhibitor (ICI) has been emerged as a major breakthrough in tumor immunotherapy, but its unique mechanism of action has also led to a number of immune-related adverse events (irAE). Type 1 diabetes mellitus (T1DM) is one of the rarest irAEs. This paper reports a case of advanced malignant liver tumor-induced T1DM who received second-line anti-PD-1 therapy and showed initial symptoms of hyperosmolar coma and hyperglycemia. In addition, the relevant literature at home and abroad was collected and reviewed, and the clinical characteristics of T1DM induced by anti-PD-1 therapy were summarized with a view to achieve early detection, diagnosis and treatment.

Abstract
Objective: To analyze the epidemiological characteristics and clinical features of the patients with 2019-nCoV infection in Nanyang City, so as to provide evidence for clinical diagnosis and treatment. Methods: The epidemiology, clinical symptoms, atory and radiologic data of 150 patients with 2019-nCoV infection admitted to the designated hospitals in Nanyang City from January 24,2020 to February 16, 2020 were retrospectively analyzed. Results: The 150 patients with 2019 nCov infection consisted of 67 men and 83 women, and the median age was (45±16) years; 69 of them were the first generation case,60 of them were the second generation case, 6 of them were the third generation case,the median incubation period of the first generation case was (5.4±2.2) days, and the second generation case was (6.7±3.1) days, and the first-generation cases are the majority in severe patients (69%) . The most common basic disease was hypertension (13 cases, 9%), diabetes (9 cases, 6%), and the most common symptom is fever(142 cases, 95%, 63% showed moderate fever) , cough and sputum(108 cases,72%), fatigue(23 cases,15%), anorexia(20 cases, 13%), headache, diarrhea, muscle soreness, sore throat as the first symptoms. The average time from onset of symptoms to consultation was (4.2±2.2) days for all patients. The changes in peripheral blood cells were mainly lymphonpenia (83 cases, 55%) and eosinophilia (95 cases, 63%), The lymphocyte count of the severe and critically ill patients was more significantly reduced, and some patients had increased myocardial enzymes, mainly LDH (47 cases, 31%), and a few patients had liver function damage, mainly manifested in ALT and AST. High, very few patients have renal impairment. Among the inflammation-related indicators, the main manifestations are increased CRP (66 cases, 43%) and ESR (86 cases, 57%), elevated D-Dimer in 29% of patients. 144 cases have different degrees of infective lesions in chest CT examination, with 30 cases (21%) on one side and 144 cases (79%) on both sides. Morphologically, most of the lesions were patchy ground glass lesions, which could be accompanied by air bronchus signs and some consolidation and paving stone signs. Of the cases showing "white lung", 87% were sever ill or critically ill. After active treatment, 45% of patients were discharged according to discharge standards. 33% of sever and critically ill patients were discharged, 49% of them were degraded hospitalization.The average length of hospitalization was (12±4) days. Conclusion: A history of epidemiological exposure, fever, chest CT with signs of pneumonia, normal or decreased WBC, and lymphocytopenia, eosinophilia are the clinical basis for the diagnosis of this disease, and most of the sever patients were the first generation cases. The degree of lymphocytopenia is related to the severity of the disease.

Abstract
Objective: To explore the effect of 18β-sodium glycyrrhetinic acid on thymic stromal lymphopoietin (TSLP) in nasal mucosa of allergic rhinitis (AR) rats. Methods: One hundred Wistar rats,half male and half female,were randomly divided into 5 groups by random number table method: control group, AR model group,budesonide group,18β-sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg groups, with 20 rats in each group. AR animal models were established by ovalbumin (OVA) sensitization in the other four experimental groups. After successful modeling, budesonide and 18β-sodium glycyrrhetinic acid were given in each group,and the detection time points were 2 weeks and 4 weeks. The distribution of TSLP in rat nasal mucosa was detected by immunohistochemistry,and the expression of TSLP in rat nasal mucosa was determined by Western blot at the protein level. The expression of TSLP-mRNA in rat nasal mucosa was detected and compared by real-time fluorescence quantitative PCR (RT-PCR) at mRNA level. The concentrations of IL-4 and OVA-sIgE in rat serum were measured and compared by ELISA. One-way analysis of variance and the least significant difference method were used for the comparison among groups, LSD t test was used for the comparison between the two groups,and the difference was statistically significant (P<0.05). Results: Immunohistochemistry confirmed existence of TSLP in rat nasal mucosa, especially in epithelial cells,endothelial cells and epithelial cilia. Western blot and RT-PCR suggested that the expression of TSLP and TSLP-mRNA in nasal mucosa of AR model group was significantly higher than that of control group (2 weeks TSLP: 1.795 9±0.131 4 vs 0.990 5±0.164 2, 4 weeks TSLP: 1.809 7±0.253 4 vs 0.870 3±0.124 4; 2 weeks TSLP-mRNA:4.582 9±0.697 7 vs 1.108 7±0.081 1, 4 weeks TSLP-mRNA:4.814 4±0.662 8 vs 1.001 0±0.155 3; all P<0.05). After 2 weeks and 4 weeks of drug intervention,the expression of TSLP and TSLP-mRNA was inhibited in nasal mucosa of budesonide group,18β-sodium sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg group,which was significantly different from that of AR model group (2 weeks TSLP: (0.897 8±0.081 8)/(1.072 1±0.113 6)/(1.396 6±0.133 9) vs 1.795 9±0.131 4; 4 weeks TSLP: (1.191 0±0.161 3)/(1.141 0±0.152 3)/(1.200 5±0.189 6) vs 1.809 7±0.253 4; 2 weeks TSLP-mRNA: (1.175 6±0.100 9)/(1.254 4±0.078 2)/(2.037 2±0.559 2) vs 4.582 9±0.697 7; 4 weeks TSLP-mRNA: (1.158 3±0.104 3)/(1.224 0±0.034 0)/(1.275 2±0.099 6) vs 4.814 4±0.662 8; all P<0.05), and not significantly different from control group. With the inhibition of TSLP, the concentrations of IL-4 and OVA-sIgE in rat serum were also decreased. Conclusion: 18β-sodium glycyrrhetinic acid has obvious inhibitory effect on TSLP in nasal mucosa of AR rats, which can control Th2 type immune inflammatory reaction.

Abstract
Objective:To observe the effect of 18β-sodium glycyrrhetinic acid(18β-SGA) on the expression of TNF-α in nasal mucosa of rats with allergic rhinitis(AR), and explore the intervention mechanism of 18β-SGA on AR. Method:One hundred and six SPF-level Wistar rats were randomly divided into control group, AR group, budesonide group, 18β-SGA low dose group and high dose group. After the AR rat model was constructed by ovalbumin, the rats were given drug intervention and sacrificed after 2 and 4 weeks of intervention. The nasal mucosa of the rats was taken for immunohistochemical staining, RT-qPCR and Western-blotting to localize and quantify the expression of TNF-α. Result:By immunohistochemistry, Western-blotting and RT-PCR, TNF-α was mainly found in the columnar epithelium, vascular endothelium, glandular and some inflammatory cytoplasm of nasal mucosa. And the expression of TNF-α in the nasal mucosa of AR rats was significantly increased than the normal group at the protein and mRNA levels (P<0.01). After intervention with different doses of 18β-SGA, the expression of TNF-α was significantly decreased (P<0.01), especially after 4 weeks of 18β-SGA low dose group(P<0.01). Conclusion:Different doses of 18β-SGA have therapeutic effects on AR, and its mechanism of action may be related to the inhibition of TNF-α expression.

Abstract
Objective: To investigate the efficacy and safety of pegaspargase, gemcitabine, and oxaliplatin(P-Gemox) chemotherapy combined with radiotherapy in the treatment of newly diagnosed, stage IE to IIE of Extranodal nasal type natural killer/T-cell lymphoma(ENKTL) patients.Method: P-Gemox chemotherapy combined with radiotherapy was used to analyze its clinical value and the factors affecting the prognosis in the treatment of 43 newly diagnosed ENKTL patients. In addition, toxicity related to chemotherapy was assessed. Result: The complete remission rate was 86.05% in 43 patients,the partial remission rate was 6.98%, and the total effective rate was 93.02%.Chi-square analysis showed tumor diameter, clinical stage and ECOG points were significant independent factors impacting on complete remission rate(P =0.025, 0.042, 0.037).The 1-year and 3-year overall survival rate and progression-free survival rate of 43 patients were 95.35% and 83.7%, 93.02% and 79.07%, respectively. Coxproportional analysis showed that tumor diameter and Ann Arbor stage were signifcant factors affecting overall survival(P =0.016,0.025).Adverse reactions caused by the P-Gemox chemotherapy regimen are mild and more common in grades I to II. Conclusion: The P-Gemox regimen combined with radiotherapy may be a promising option in the treatment of newly-diagnosed ENKTL due to its high efficacy yet low toxicity, and clinical stage has an important effect on CR and OS.

Abstract
Objective: Breast cancer stem cells (BCSC) have been suggested to have clinical implications for cancer therapeutics because of their proposed role in chemo-resistance. The aim of this study was to investigate effects of BCSC on endocrine therapy response by regulating PI3K/Akt/mTOR signaling pathway. Methods: We evaluated the susceptibility of BCSC to NVP-BKM120 (BKM120), a new generation of PI3K-specific inhibitor, when used individually or in combination with letrozole in vivo. For this, a stem-like cell population (SC) was enriched from breast cancer cell line MCF-7 after mammosphere cultures. We have constructed high aromatase expression BCSC (BCSC-CYP19) and non-stem cells (MCF-7-CYP19) subcloning. We demonstrate BKM120 inhibits growth, generation of drug-resistant derivatives and SC formation in BCSC-CYP19 and MCF-7-CYP19. Result: BKM120 could inhibit BCSC-CYP19 growth by dose-dependence, reduce migration and colony formation of BCSC-CYP19, and also significantly reduced expression of PI3K, Akt1 and S6. Combined BKM120 and letrozolecaninhibit BCSC-CYP19 growth and proliferation, make BCSC-CYP19 stayed in G0-G1 phase increasing significantly to induce early apoptosis, and down-regulate expression of PI3K, Akt1 and S6. Conclusion: PI3K/Akt/mTOR pathway effects on letrozole resistance by regulating BCBSs characteristics. Combination of PI3K inhibitor BKM120 and letrozole could reduce letrozole resistance.

Abstract
Objective: To explore the interaction of smoking and diabetes on stroke. Methods: In this case-control study, a face to face questionnaire survey was conducted. Logistic regression models were used to analyze the relationship between smoking or diabetes and stroke. The indicators of interaction were calculated according to the Bootstrap method in this study. Results: A total of 918 cases and 918 healthy controls, who participated in the chronic disease risk factor survey in Xuzhou in 2013, were included in this study. Logistic regression analysis found that cigarette smoking was associated with stroke (OR=1.63, 95%CI: 1.33-2.00), and diabetes was also associated with stroke (OR=2.75, 95%CI: 2.03-3.73) after adjusting confounders. Compared with those without diabetes and smoking habit, the odds ratio of stroke in those with diabetes and smoking habits was 8.94 (95%CI:3.77-21.19). Diabetes and smoking combined interaction index was 3.65 (95%CI: 1.68-7.94), the relative excess risk was 5.77 (95%CI: 0.49-11.04), the attributable proportion was 0.65 (95%CI: 0.42-0.87). Conclusion: The results suggest that there are additive interactions between smoking and diabetes on stroke.

Abstract
Objective: To evaluate the safety and effectiveness of esophageal replacement with ileocolon graft. Methods: Totally 34 cases of esophageal replacement with ileocolon graft from July 2015 to November 2017 at Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiaotong University were analyzed retrospectively, including 24 male and 10 female, aging from 7 to 72 years old. Esophageal replacement with ileocolon graft by right and/or middle colic artery as a blood supply using retrosternal route except one subcutaneous route. The primary esophageal disease, postoperative complication rate and quality of life were analyzed. Results: The overall postoperative complication rate was 23.5% (8/34), cervical anastomotic leakage rate of 5.9% (2/34), necrosis of colon graft of 5.9% (2/34). There were 3 patients experienced re-operation including 2 patients with colon graft necrosis and 1 patient with intestinal obstruction after ERC. One patient with colon graft necrosis died of septic shock after reoperation. Six cases of cervical esophago-jejunal anastomosis stenosis and 1 case of diarrhea occurred in the later time. All patients were followed up for a median time of 9 months (range: 1 to 28 months), 32 cases survived but 1 patient died until last follow-up by the end of December 2017. Conclusion: Esophageal replacement with ileocolon graft by right and/or middle colic artery as a blood supply using retrosternal route was safe and effective.

Abstract
Objective: To investigate the usefulness of adrenal androgens for assessing the selectivity of adrenal venous sampling (AVS). Methods: Between January 2010 and December 2016, 37 consecutive patients [with an average age of (47±14) years, 16 males and 21 females] with primary aldosteronism (PA) who underwent AVS were enrolled. AVS procedures were performed with the bilateral simultaneous technique without cosyntropin stimulation. Cortisol, androstenedione, dehydroepiandrosterone (DHEA), and DHEA sulfate (DHEAS) concentrations were measured in adrenal venous (AV) and peripheral venous (PV) samples, respectively. Results: The selectivity index (SI) based on androstenedione and DHEA was higher than that of cortisol (SI-left: 13.9, 13.1 vs 6.05, P=0.006, 0.035; SI-right: 30.4, 18.5 vs 11.6, P=0.028, 0.051). However, the SI based on DHEAS was lower than that of cortisol (SI-left: 1.3 vs 6.0, P=0.002; SI-right: 1.5 vs 11.6, P=0.038). Plasma androstenedione and DHEA concentrations were positively correlated with cortisol and aldosterone in AV samples (all P<0.001). Compared to cortisol, the variation ratio of AV androstenedione and DHEA was lower from t(-15) to t(0) (0.23, 0.43 vs 0.52, both P<0.05). Using the receiver operating characteristic curve, a SI ≥ 3.0 for androstenedione or DHEA provided optimal sensitivity(97.7%, 91.9%) and specificity (93.8%, 93.8%) in AVS. Conclusion: Given the greater AV/PV ratios and reduced variability compared to cortisol, the adrenal androgens androstenedione and DHEA are useful for assessing the selectivity of AVS without cosyntropin stimulation and may be superior analytes in conditions with marked variability of cortisol levels or with adrenocortical tumors co-secreting cortisol and aldosterone.

Abstract
AIM Perineal wound complications after abdominoperineal resection (APR) have become a major clinical challenge. Myocutaneous flap closure has been proposed in place of primary closure to improve wound healing. We conducted this comprehensive meta-analysis to evaluate the current scientific evidence of primary closure vs myocutaneous flap closure of perineal defects following APR for colorectal disease. METHODS We systematically searched the MEDLINE, Embase, PubMed, Web of Science and Cochrane Library databases to identify all relevant studies. After data extraction from the included studies, meta-analysis was performed to compare perioperative outcomes of primary closure and myocutaneous flap closure. RESULTS Eighteen studies with a total of 17 913 patients (16 346 primary closure vs 1567 myocutaneous flap closure) were included. We found that primary closure was significantly associated with higher total perineal wound complications (P = 0.007), major perineal wound complications (P < 0.001) and perineal wound infection (P = 0.001). On the other hand, myocutaneous flap closure takes more operation time (P < 0.001) and increases the risk of perineal wound dehiscence (P = 0.01), deep surgical site infection (P < 0.001), enterocutaneous fistulas (P = 0.03) and return to the operating room (P = 0.0005). There were no significant differences between the two groups for other outcomes. CONCLUSIONS This is the first systematic review with meta-analysis comparing primary closure with myocutaneous flap closure of perineal defects after APR for colorectal disease. Although taking more operation time and an increased risk of specific complications, the pooled results have validated the use of myocutaneous flaps for reducing total/major perineal wound complications. More investigations are needed to draw definitive conclusions on this dilemma.

Abstract
Objective: To assess the clinical value for the clinicopathological features of microcystic elongated and fragmented (MELF) invasion in endometrial carcinoma (EEC) . Methods: The clinicopathological data of 108 cases of endometrial carcinoma with total hysterectomy, bilateral adnexectomy, and pelvic dissection were retrospectively analysis in Peking University People's Hospital from April 2015 to October 2016. Twenty-five patients with endometrial carcinoma showing MELF invasion pattern were collected. We analyzed retrospectively the association of MELF pattern invasion with clinical pathology data and prognosis of the patients, partial immunohistochemical staining was implemented. MELF invasion was a special invasion pattern and characterized by microcystic, elongated, fragmented (composed of cluster cells) gland in muscular layer. Results: The incidence rate was 23.1% (25/108). These patients mean age was (59.3±10.9) years old. Four cases were premenopausal, and 21 were postmenopausal. Abnormal vaginal bleeding was the main clinical presentation. The lesions tend to appear adjacent to the tumor body. Sometimes, it may be appears away from the tumor body in the deep muscle layer.Lymph node metastasis were present in 5 cases (20%, 5/25). Thirteen cases (52%, 13/25) of them demonstrated lymph vascular space involvement (LVSI). The immunohischemical expression of ER,PR, Ki-67 and galectin-3 showing MELF invasion pattern were weaker than no showing MELF invasion pattern endometrial carcinoma, cktokeratin (CK) was showed diffuse strong positive expression, E-cadherin was moderately positive expression. All 25 cases were followed up for (23.2±5.9) months (14-33 months) after the therapy with no recurrence on metastasis. Conclusions: MELF invasion pattern is a special invasion pattern in low-grade EEC. The incidence of LVSI and lymph node metastasis rate in endometrial carcinoma with MELF invasion are significantly increased. The prognosis of MELF invasion pattern may be poor.

Abstract
Objective: To investigate the therapeutic efficacy and safety of CT-guided radiofrequency ablation(RFA)combined with biopsy synchronously to multiple small nodules of metastatic tumors in lung. Method: From January 2016 to December 2016, a total of 86 patients in the General Hospital of People's Liberation Army with 144 lesions were divide into two groups(all the lesions were less than 1 cm). Group A with 51 cases located in the lung periphery underwent biopsy prior to RFA.Group B with 35 cases located in the middle and inner side of lung adjacent to the vasculatures contrarily underwent RFA first.The changes of these lesions during the 1 to 12-month were followed up. Results: All the procedures were completed successfully.The intra operative CT scanning showed the ablation zones were completely covered by the indicative "halo sign" respectively.The P value was 0.818, 0.155 and 0.452 respectively, in the number of nodules, pathological results positive rate and complications in the rank and inspection for A, B two groups, which were all higher than 0.05.Though different strategies according to different location of the nodes, the two groups can achieve safe and effective treatments.All patients in two groups had high density ablation zones on their 1-month post operative CT without enhancement.3-and 6-post operative CT illustrated a decrease of lesions, 12-month post operative CT showed the lesions turned to fibrous stripes. Conclusion: The CT-guided RFA combined with biopsy synchronously to multiple small nodules of metastatic tumors in lung is safe and effective, for the lesions located in the middle or inner side of lung, RFA prior to the biopsy can avoid the massive hemoptysis.

Abstract
Objective: To explore the prognosis of patients with T1b stage gallbladder carcinoma underwent different surgical procedure. Methods: The clinicopathological data of 97 patients with T1b stage gallbladder carcinoma came from 8 clinical centers from January 2010 to December 2016 and 794 patients who were admitted to the SEER database of USA from January 1973 to December 2014 were analyzed.There were 891 patients including 254 males and 637 females (1.0∶2.5) with age of (69.5±12.0)years. There were 380 patients who were less than 70 years old, 511 patients who were more than 70 years old. And there were 213 patients with the diameter of tumor less than 20 mm, 270 patients with the diameter of tumor more than 20 mm, 408 patients were unclear. There were 196 patients with well differentiation, 407 patients with moderately differentiation, 173 patients with poorly differentiation, 8 patients with undifferentiated, 107 patients were unclear. In the 891 patients with T1b stage gallbladder carcinoma, there were 562 cases accepted the simple cholecystectomy, 231 cases with simple cholecystectomy plus lymphadenectomy, and 98 cases with radical cholecystectomy. The time of follow-up were until June 2017. χ(2) test was used to analyze the enumeration data, rank-sum test was used to analyze the measurement data, the analyses of prognostic factors were used Cox proportional hazards model, the survival analysis was performed using Kaplan-Meier method. Results: The results of Cox proportional hazards model indicated, age, differentiation, surgical procedure were the risk factors of prognostic(1.929(1.594-2.336), P<0.01; 1.842(1.404-2.416), P<0.01; 1.216(0.962-1.538), P<0.01). The results of Kaplan Meier test indicated, the overall survival of T1b stage gallbladder carcinoma were (85.5±3.8)months, the overall survival of patients with simple cholecystectomy were (71.3±4.4)months, the overall survival of patients with cholecystectomy plus lymphadenectomy were(87.6±5.8)months, and the overall survival of patients with radical cholecystectomy were(101.7±9.3)months. The overall survival of patients with cholecystectomy plus lymphadenectomy and radical cholecystectomy were more than simple cholecystectomy(P<0.05). There were 329 patients with Lymph nodes examined in and after operations(231 patients with cholecystectomy plus lymphadenectomy, 98 patients with radical cholecystectomy). There were 265 patients with negative lymph node metastasis, the overall survival were(98.3±4.2)months. There were 64 patients with positive lymph node metastasis, the overall survival were(75.5±3.1)months. The overall survival of 38 patients with cholecystectomy plus lymphadenectomy were(62.7±2.6) months, and 26 patients with radical cholecystectomy were (82.2±3.7)months. The overall survival of patients with radical cholecystectomy were more than cholecystectomy plus lymphadenectomy(P<0.05). Conclusions: The T1b stage gallbladder carcinoma patients with cholecystectomy plus lymphadenectomy or radical cholecystectomy has improved the prognosis comparing with simple cholecystectomy, significantly. When lymph node metastasis occurs, radical cholecystectomy has improved the prognosis comparing with cholecystectomy plus lymphadenectomy.

Abstract
Algae is a well-known organism that its characteristic is prominent for biofuel production and wastewater remediation. This critical review aims to present the applicability of algae with in-depth discussion regarding three key aspects: (i) characterization of algae for its applications; (ii) the technical approaches and their strengths and drawbacks; and (iii) future perspectives of algae-based technologies. The process optimization and combinations with other chemical and biological processes have generated efficiency, in which bio-oil yield is up to 41.1%. Through life cycle assessment, algae bio-energy achieves high energy return than fossil fuel. Thus, the algae-based technologies can reasonably be considered as green approaches. Although selling price of algae bio-oil is still high (about $2 L-1) compared to fossil fuel's price of $1 L-1, it is expected that the algae bio-oil's price will become acceptable in the next coming decades and potentially dominate 75% of the market.

Abstract
Antibiotics and hormones in swine wastewater have become a critical concern worldwide due to the severe threats to human health and the eco-environment. Removal of most detectable antibiotics and hormones, such as sulfonamides (SAs), SMs, tetracyclines (TCs), macrolides, and estrogenic hormones from swine wastewater utilizing various biological processes were summarized and compared. In biological processes, biosorption and biodegradation are the two major removal mechanisms for antibiotics and hormones. The residuals in treated effluents and sludge of conventional activated sludge and anaerobic digestion processes can still pose risks to the surrounding environment, and the anaerobic processes' removal efficiencies were inferior to those of aerobic processes. In contrast, membrane bioreactors (MBRs), constructed wetlands (CWs) and modified processes performed better because of their higher biodegradation of toxicants. Process modification on activated sludge, anaerobic digestion and conventional MBRs could also enhance the performance (e.g. removing up to 98% SMs, 88.9% TCs, and 99.6% hormones from wastewater). The hybrid process combining MBRs with biological or physical technology also led to better removal efficiency. As such, modified conventional biological processes, advanced biological technologies and MBR hybrid systems are considered as a promising technology for removing toxicants from swine wastewater.

Abstract
This study aimed to evaluate the impact of C/N ratio on the performance of a hybrid sponge-assisted aerobic moving bed-anaerobic granular membrane bioreactor (SAAMB-AnGMBR) in municipal wastewater treatment. The results showed that organic removal efficiencies were above 94% at all C/N conditions. Nutrient removal was over 91% at C/N ratio of 100/5 but was negatively affected when decreasing C/N ratio to 100/10. At lower C/N ratio (100/10), more noticeable membrane fouling was caused by aggravated cake formation and pore clogging, and accumulation of extracellular polymeric substances (EPS) in the mixed liquor and sludge cake as a result of deteriorated granular quality. Foulant analysis suggested significant difference existed in the foulant organic compositions under different C/N ratios, and humic substances were dominant when the fastest fouling rate was observed. The performance of the hybrid system was found to recover when gradually increasing C/N ratio from 100/10 to 100/5.

Abstract
Objective:To evaluate the values of magnetic resonance (MR) in the diagnosis of middle ear cholesteatoma by meta-analysis. Method:The articles concerning the diagnosis of middle ear cholesteatoma by using MRI until September 2017 were searched in databases including The Cochrane Library, PubMed, CBM, VIP, Wan Fang Data and CNKI with the search term "cholesteatoma, MR, Magnetic Resonance". Two independent researchers screened literature, extracted data, and assessed the risk of the bias of included studies with the inclusion and exclusion criteria using the QUADAS-2 tool. Then, meta-analysis was performed using Stata 12.0 software. The pooled weighted sensitivity and specificity were calculated, the summary receiver operating characteristic curve (SROC) was drawn and the area under the curve was calculated. Result:A total of 21 original studies were included. The results of meta-analysis showed that the pooled sensitivity, specificity, DOR and area under SROC curve of MR for diagnosing middle ear cholesteatoma were 0.88 (95%CI0.83 to 0.92), 0.91 (95%CI0.86 to 0.95), 10.13 (95%CI6.20 to 15.55), 0.13 (95%CI0.09 to 0.19), 79.23 (95%CI37.74 to 166.33), and 0.96 (95%CI0.93 to 0.97), respectively. The 1.5T MR has little differences with 1.5T MR in diagnosing middle ear cholesteatoma. In contrast to retrospective studies, prospective studies have further demonstrated that MR has a higher diagnostic value for middle ear cholesteatoma. Based on regions, the analysis showed that MR in Europe was more valuable in the diagnosis of middle ear cholesteatoma. Conclusion:In the diagnosis of middle ear cholesteatoma, MR has a high value.

Abstract
Objective: To investigate the role of adrenal vein sampling (AVS) in identifying the subtype of primary aldosteronism (PA). Methods: AVS was performed in 50 patients who were confirmed as PA between September 2010 and September 2016 in Nanjing Drum Tower Hospital. Clinical, biochemical and follow-up data were reviewed retrospectively. Bilaterally simultaneous catheterization without cosyntropin stimulation and contemporaneous cortisol measurement during AVS were used. Selectivity index (SI)≥1.5 suggested that the sample was from the adrenal vein.Lateralization index (LI) ≥2 suggested unilateral disease.Clinical data was further compared and the AVS findings were analyzed. Results: AVS was successful performed in 41 cases of 50 patients, and the success rate was 82%. According to the results of AVS and postoperative pathology, 41 cases were divided into aldosterone-producing adenoma (APA)/unilateral adrenal hyperplasia (UAH) group (24 cases) and idiopathic hyperaldosteronism (IHA) group (17 cases). Compared with IHA group, patients with APA/UAH showed longer duration of hypertension[10.0 (5.0, 13.0) y vs 4.0 (2.0, 8.0) y, P=0.046], higher proportion of hypokalemia (95.8% vs 64.7%, P=0.009). Furthermore, patients with APA/UAH demonstrated lower plasma renin activity (P=0.089), higher plasma aldosterone concentration and aldosterone to renin ratio (ARR) (both P<0.05). The diagnostic concordance between CT and adrenal vein sampling was only 48.8%(20/41). Conclusions: The application of bilaterally simultaneous catheterization and contemporaneous cortisol measurement improves success rate and diagnostic accuracy of AVS. AVS is useful in subtype diagnosis of PA with equivocal imaging findings.

Abstract
OBJECTIVE To observe the effect of manual acupuncture intervention on serotonin transporter (5-HTT), 5-HT 1 A receptor (5-HT1AR), norepinephrine (NE) alpha receptor 2 (NEα2R) protein of brain tissues in rats with post-stroke depression (PSD). METHODS Forty SD rats were randomly divided into normal group, model group, medication group and acupuncture group, with 10 rats in each. The PSD model was established by the combination of middle cerebral artery occlusion and chronic non- predictable mild stress. Rats of the medication group were treated by gavage of fluoxetine (2 mg/kg, once daily for 21 days), and those of the acupuncture group treated by manual acupuncture stimulation of "Baihui"(GV 20), "Fengfu" (GV 16), bilateral"Shenmen" (HT 7) and "Taichong" (LR 3) for 20 min, once a day for 21 days, with one day's interval between each every 7 days. The animals' neurological deficit was detected by Zea Longa's scaling, and the depression status assessed by sugar solution consumption, and the locomotor activity (crossing and rearing times in 5 min) detected by open-field tests. The contents of 5-HT, NE, acetylcholine (ACh), gamma aminobutyric acid (GABA), and glutamate (Glu) of the cerebral cortex were detected using high performance liquid chromatography (HPLC) and expression levels of 5-HTT, 5-HT1AR, NEα2R proteins of the hippocampus, raphe nuclei and locus coeruleus(LC) tissues detected using western blotting (EB), respectively. RESULTS After modeling, the neurological deficit score was significantly increased, while the sugar solution consumption and the locomotor activities (crossi-ng and rearing times in 5 min) were notably decreased (P<0.05, P<0.001). Findings of HPLC and WB indicated that after modeling, the cerebrocortical 5-HT and NE contents and 5-HTT protein expression levels in the hippocampus, raphe nucleus and LC were obviously decreased and the cortical ACh, GABA and Glu contents as well as the expression of 5-HT1AR and NEα2R proteins in the hippocampus, raphe nucleus and LC considerably increased in the model group (P<0.01). Following acupuncture intervention and medication, the increased neurological deficit score, cortical ACh, GABA and Glu contents, and the expression le-vels of 5-HT1AR and NEα2R proteins in the hippocampus, rahpe nucleus and LC, as well as the decreased sugar solution consumption, crossing and rearing times of open field tests, cortical 5-HT and NE contents, as well as cortical 5-HT protein expression were all reversed in both acupuncture and medication groups (P<0.05, P<0.01). No significant differences were found between the acupuncture and medication groups in all the above-mentioned indexes (P>0.05). CONCLUSIONS Acupuncture can improve the locomotor function changes in stroke rats with depression after stroke, which may be associated with its effects in suppressing the up-regulated cortical ACh, GABA, Glu contents, the expression levels of 5-HT1AR and NEα2R proteins in the hippocampus, raphe nucleus and LC, and the down-regulated 5-HT and NE contents in the cerebral cortex and 5-HTT protein expression levels in the hippocampus, raphe nucleus and LC.

Abstract
Acyl-coenzyme A cholesterol acyltransferase (ACAT) plays an important role in maintaining cellular and organismal cholesterol homeostasis. Two types of ACAT isozymes with different functions exist in mammals, named ACAT-1 and ACAT-2. Numerous studies showed that ACAT-2 selective inhibitors are effective for the treatment of hypercholesterolemia and atherosclerosis. However, as a typical endoplasmic reticulum protein, ACAT-2 protein has not been purified and revealed, so combinatorial ligand-based methods might be the optimal strategy for discovering the ACAT-2 selective inhibitors. In this study, selective pharmacophore models of ACAT-1 inhibitors and ACAT-2 inhibitors were built, respectively. The optimal pharmacophore model for each subtype was identified and utilized as queries for the Traditional Chinese Medicine Database screening. A total of 180 potential ACAT-2 selective inhibitors were obtained, which were identified using an ACAT-2 pharmacophore and not by our ACAT-1 model. Selective SVM model and bioactive SVR model were generated for further identification of the obtained ACAT-2 inhibitors. Ten compounds were finally obtained with predicted inhibitory activities toward ACAT-2. Hydrogen bond acceptor, 2D autocorrelations, GETAWAY descriptors, and BCUT descriptors were identified as key structural features for selectivity and activity of ACAT-2 inhibitors. This study provides a reasonable ligand-based approach to discover potential ACAT-2 selective inhibitors from Chinese herbs, which could help in further screening and development of ACAT-2 selective inhibitors.
