Abstract
OBJECTIVE To estimate the univariate heritability of resting heart rate and common chronic disease such as hypertension, diabetes, and dyslipidemia based on extended pedigrees in Fujian Tulou area and to explore bivariate heritability to test for the genetic correlation between resting heart rate and other relative phenotypes. METHODS The study was conducted in Tulou area of Nanjing County, Fujian Province from August 2015 to December 2017. The participants were residents with Zhang surname and their relatives from Taxia Village, Qujiang Village, and Nanou Village or residents with Chen surname and their relatives from Caoban Village, Tumei Village, and Beiling Village. The baseline survey recruited 1 563 family members from 452 extended pedigrees. The pedigree reconstruction was based on the family information registration and the genealogy booklet. Univariate and bivariate heritability was estimated using variance component models for continuous variables, and susceptibility-threshold model for binary variables. RESULTS The pedigree reconstruction identified 1 seven-generation pedigree, 2 five-generation pedigrees, 23 four-generation pedigrees, 186 three-generation pedigrees, and 240 two-generation pedigrees. The mean age of the participants was 57.2 years and the males accounted for 39.4%. The prevalence of hypertension, diabetes, dyslipidemia in this population was 49.2%, 10.0%, and 45.2%, respectively. The univariate heritability estimation of resting heart rate, hypertension, and dyslipidemia was 0.263 (95%CI: 0.120-0.407), 0.404 (95%CI: 0.135-0.673), and 0.799 (95%CI: 0.590-1), respectively. The heritability of systolic blood pressure, diastolic blood pressure, fasting glucose, total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol was 0.379, 0.306, 0.393, 0.452, 0.568, 0.852, and 0.387, respectively. In bivariate analysis, there were phenotypic correlations between resting heart rate with hypertension, diabetes, diastolic blood pressure, fasting glucose, and triglyceride. After taking resting heart rate into account, there were strong genetic correlations between resting heart rate with fasting glucose (genetic correlation 0.485, 95%CI: 0.120-1, P<0.05) and diabetes (genetic correlation 0.795, 95%CI: 0.181-0.788, P<0.05). CONCLUSION Resting heart rate was a heritable trait and correlated with several common chronic diseases and related traits. There was strong genetic correlation between resting heart rate with fasting glucose and diabetes, suggesting that they may share common genetic risk factors.

Abstract
Objective: To investigate the strong expression (S+) of P53 and BCL2 proteins in MYC/BCL2 double-expression DLBCL (DEL) and whether they can be used for the prognostic evaluation and stratified diagnosis of DELs. Methods: Tissue microarray were made by filed FFPE blocks of 174 DLBCL cases. The translocation of MYC, BCL2 and BCL6 genes were detected by FISH, and the proteins were detected by IHC. Data of clinicopathologic features and follow up of patients were collected and OS (overall survival) and PFS (progression free survival) were analyzed by statistics. Results: Eight double-hit lymphomas (DHLs) were identified in all cases, and 45 DELs were selected from 166 remaining cases, which have no significant difference in OS and PFS compared with non-DEL cases (P=0.668 and P=0.790) . Of 42 DEL-cases with follow up data, 24 cases with P53+ or/and BCL2 (S+) are significantly shorter OS and PFS than others (P=0.003 and P=0.000) , in which the cases with P53+/BCL2 (S+) co-expression were the worst prognosis, and P53/BCL2 co-weaker positive DEL cases even have superior OS and PFS than those non-DELs. Although statistics showed that the cases of P53+ or/and BCL2 (S+) have a lower OS and PFS in total cases (P=0.063 and P=0.024) , it is not the case when the DEL-cases take out from total cases, that is the cases with P53+ or/and BCL2 (S+) are as similar OS and PFS as others in non-DEL group (P=0.590 and P=0.550) . Conclusion: The strong expression of P53 and BCL2 proteins can be used as indicators of stratified diagnosis and poor prognosis of DEL.

Abstract
Objective: To compare long-term efficacy between watch and wait (W&W) strategy and total mesorectal excision (TME) in patients who were diagnosed with locally advanced rectal cancer (LARC) and attained clinical complete response (cCR) after neoadjuvant chemoradiotherapy (nCRT). Methods: A retrospective cohort study was carried out. A total of 238 patients with stage II-III LARC exhibiting cCR after nCRT in Sun Yat-sen University Cancer Center from September 16, 2010 to January 9, 2018 were enrolled. Patients who were diagnosed with other malignant tumor within 5 years, did not receive regular follow-up in our center for more than 1 year and had no complete examination items after nCRT were excluded. Of 238 patients, 151 were male and 87 were female with a median age of 57 (27-83) years old. According to TNM stage, 61 cases were cII, 177 cases were cIII. Concurrent chemoradiotherapy (CCRT) was performed in 20 patients. CCRT plus induction/consolidated chemotherapy was performed in 218 patients. Intensity-modulated radiotherapy (IMRT) was applied to radiotherapy. The median radiation dose was 50 Gy/25 Fr for both the primary tumor and clinical target volumes, and the total dose was 45.0 to 50.6 Gy for 227 patients. In 27 patients, single-agent fluorouracil or capecitabine was used as concurrent chemotherapy. But in the other 211 patients, a combined regimen of oxaliplatin and fluorouracil or capecitabine was used. After nCRT, 59 and 179 patients received W&W (W&W group) and TME 6-12 weeks later (TME group), respectively. After the ending of treatment, patient was interviewed one time every 3 months and after 3 years, one time every six months. Overall survival (OS) rate, distant-metastasis-free survival (DMFS) rate, and local-recurrence-free survival (LRFS) rate were compared between two groups. The salvage treatment and sphincter preservation rate were analyzed. The survival curve was drawn with Kaplan-Meier method and evaluated by log-rank method. Results: In the cases treated with TME, the median interval from nCRT to surgery was 59 days. The postoperative pCR rate was 63.1%(113/179). The median follow-up time of the whole cohort was 41.8 (12.0-99.0) months. The 3-year and 5-year OS rates were 98.4% and 96.5%; the 3-year and 5-year LRFS rates were 96.5% and 96.5%; the 3- and 5-year DMFS rates were 91.0% and 87.9%, respectively. The 3-year OS rates in the W&W group and the TME group were 100% and 97.9%; the 5-year OS rates in W&W group and the TME group were 90.6% and 97.9% (P=0.339); The 3-year local recurrence rate (LRR) in the W&W group was 12.9% (7 cases recurred within 2 years), which was significanthy higher then that in the TME group (0.6%, P=0.003). Salvage surgery was successful in 5/6 cases. After salvage surgery, LRFS rate was not significantly different between the two groups (P=0.137). The 3-year DMFS rate in the W&W group and the TME group were 88.4% and 81.1%, whose difference was not significant (P=0.593). Recurrence with simultaneous metastasis was seen in 3/7 cases of the W&W group. The sphincter was preserved in 89.8% (53/59) of patients in the W&W group, which was significantly higher than 73.7% (132/179) in the TME group (P<0.001). When distance of tumor from the anal verge was ≤ 5 cm, the sphincter preservation rate (SPR) in the W&W group was 88.0% (44/50), which was significantly higher than the 54.4% (56/103) in the TME group (P<0.001). Conclusions: W&W is safe and feasible for patients with LARC and cCR after nCRT. The results should be verified by further clinical trials.

Abstract
Esfenvalerate is a pyrethroid insecticide used widely for agricultural and residential applications. This insecticide has been detected in aquatic environments at concentrations that can induce sub-lethal effects in organisms. In this study, zebrafish embryos were used to examine the effects of environmentally-relevant concentrations of esfenvalerate on development and behavior. It was hypothesized that esfenvalerate exposure would impair locomotion due to its effects on the central nervous system. We also measured mitochondrial bioenergetics and the expression of genes (dopamine system) as putative mechanisms of locomotor impairment. Concentrations of 0.02, 0.2 and 2 μg/L esfenvalerate did not induce significant mortality nor deformity in zebrafish, but there was an acceleration in hatching time for zebrafish exposed to 2 μg/L esfenvalerate. As an indicator of neurotoxicity, the Visual Motor Response (VMR) test was conducted with 5, 6, and 7 dpf zebrafish after continuous exposure, and higher concentrations were used (4 and 8 μg/L esfenvalerate) to better discern age-and dose dependent responses in behavior. Experiments revealed that, unlike the other stages, 6 dpf larvae showed evidence for hypo-activity with esfenvalerate, suggesting that different stages of larval development may show increased sensitivity to pyrethroid exposure. This may be related to age-dependent maturation of the central nervous system. We hypothesized that reduced larval activity may be associated with impaired production of ATP and the function of mitochondria at earlier life stages, however dramatic alterations in oxidative phosphorylation were not observed. Based on evidence that dopamine regulates behavior and studies showing that other pyrethroids affect dopamine system, we measured transcripts involved in dopaminergic signaling. We found that dopamine active transporter was down-regulated with 0.2 μg/L esfenvalerate. Lastly, we comprehensively summarize the current literature (>20 studies) regarding the toxicity of pyrethroids in zebrafish, which is a valuable resource to those studying these pesticides. This study demonstrates that esfenvalerate at environmentally-relevant levels induces hypoactivity that are dependent upon the age of the zebrafish, and these behavioral changes are hypothesized to be related to impaired dopamine signaling.

Results: 5 male and 4 female was included in those 9 patients, whose median age was 36 years, and the age range from 15 to 49 years. 8 of these patients had no underlying disease and one suffered from diabetes. 7 patients had a history of travel to Wuhan City or Hubei Province, and one patient was a medical staff. Two family clustered was found. The incubation period was 1 to 6 days. The clinical manifestations were fever in 8 cases (8/9) , dry cough in 5 cases (5/9) , pharyngalgia in 4 cases (4/9) , fatigue in 4 cases (4/9) , body soreness in 4 cases (4/9) , and blocked or watery nose in 1 case (1/9) . Six patients (6/9) had abnormal cell peripheral blood, of which 3 (3/9) had an increased monocyte count, 2 (2/9) had a reduced lymphocyte , and 1 (1/9) had an increased leukocyte count, while the 3 patients had normal cell blood routines. The median of CRP was 16.3 mg/L, including 5 patients with slightly elevated (5/9) , 4 patients with normal values (4/9) . the results of procalcitonin test were negative in5 patients. Three patients were examined by chest X-ray examination, one of which was normal, one case showed infiltrates of right upper lung, and another showed in right lower lung. All patients underwent chest HRCT. And 7 cases (7/9) showed multiple ground glass exudation, including 5 cases (5/7) involved bilateral lungs, 2 cases (2/7) involved unilateral lung, 3 cases (3/7) with patchy consolidation, and 2 cases (2/9) showed no abnormality. Conclusions: The patents with 2019 novel coronavirus pneumonia in this study generally have an epidemiological history. The clinical manifestations are fever and cough. Peripheral white blood cell counts were most normal And PCT were all negative. Chest HRCT manifested as multiple ground-glass opacities with partly consolidation. Some patients had normal chest radiographs but HRCT showed pneumonia. Some patients had no pneumonia on chest HRCT.

Abstract
Objective: To explore the clinical characteristics and genotyping results of childhood-onset myoclonus dystonia syndrome caused by SGCE variants. Methods: The clinical data of 9 children with SGCE-related myoclonus dystonia syndrome admitted at either the Department of Neurology, Beijing Children's Hospital, Capital Medical University or the Department of Pediatrics, Peking University First Hospital from May 2018 to October 2019 were collected and the patients were followed up. The definite diagnosis was made on the basis of whole exome sequencing and multiple ligation-dependent probe amplification. The clinical features and gene test results were analyzed retrospectively. Results: Data of 9 patients (4 boys and 5 girls) diagnosed as myoclonus dystonia syndrome caused by SGCE variants were collected. The onset age ranged from 1 year to 3 years and 2 months. The first symptom was myoclonus in 4 cases, while dystonia in the remaining 5 cases. In the course of the disease, 9 cases had myoclonus and 8 had dystonia. Myoclonic jerks were characterized by involuntary jerks in both upper limbs in 8 patients. Six patients had involuntary jerks of lower limbs, resulting in gait instability or even falling. The myoclonus was exacerbated during the fine motor activities, emotional stress or fatigue. Dystonia was characterized by abnormal gait, including 5 cases with right leg dystonia, and 3 cases with the left leg dystonia. Three probands had a positive family history. Intellectual development was normal in all cases. There was no obvious abnormality in video-electroencephalogram (EEG) during both ictal and interictal periods. Electromyography (EMG) and brain magnetic resonance imaging (MRI) of 9 patients were normal. Nine patients carried SGCE gene variants, including 3 frame shift variants, 2 nonsense variants, 2 missense variants, 1 fragment deletion variant and 1 splice site variant. Seven variants were inherited paternally, and 2 variants were de novo. Madopar was used in 8 patients, and nitrazepam in 4 patients, leading to the decrease in the myoclonus jerks and improvement of gait in 6 and 2 patients, respectively. Conclusions: SGCE gene variants can cause myoclonus dystonia syndrome. The onset of the disease may occur at infancy or preschool age, with either myoclonic jerks or dystonia as the initial symptom. Non-epileptic myoclonus is the prominent symptom, with upper limb mainly involved. Most of the patients have the accompanying symptoms of dystonia, and some of them may have spontaneous symptom relief. SGCE gene is imprinted maternally, and the inherited variants of SGCE are paternal in origin.

Abstract
Objective: To evaluate the application of combinatorial probe anchor synthesis (cPAS)-based high-throughput low coverage whole genome sequencing in chromosomal aberration detection in spontaneous miscarriage. Methods: From September 2015 to May 2017, spontaneous miscarriage samples were collected from Inner Mongolia Maternal and Child Health Care Hospital. Those samples were further analyzed with two independent methods, fluorescence in situ hybridization (FISH) and low coverage whole genome sequencing on the BGISEQ-500 high-throughput platform. The performance of low coverage whole genome sequencing was assessed by comparing to FISH results. Results: In 595 spontaneous miscarried specimens, low coverage whole genome sequencing revealed 144 cases (24.2%, 144/595) chromosomal abnormalities, of which a subset of 137 cases (23.0%, 137/595) were detected as aneuploidies, 2 cases (0.3%, 2/595) as mosaicisms and 5 cases (0.8%, 5/595) as copy number variation (≥5 Mb). Conclusion: cPAS-based high-throughput low coverage whole genome sequencing is a reliable method in detecting chromosomal aberrations inspontaneous abortion tissues, including chromosome aneuploidies, mosaicisms and copy number variation (≥5 Mb).

Abstract
Objective: To investigate the characteristics of frailty in the elderly male patients with chronic kidney disease (CKD) and the effects of renal function on the incidence of frailty. Methods: A total of 105 non-dialysis CKD patients aged ≥65 years who were admitted to the Chinese PLA General Hospital between October 1, 2018 and January 30, 2019 were included in this study. Their clinical data and laboratory indicators were collected. Frailty was defined according to Fried frailty criteria. According to the frailty scores, the participants were categorized as non-frail (n=37), intermediately frail (n=37) and frail (n=31). The association of frailty and the level of estimated glomerular filtration rate (eGFR) in the patients was analyzed using the model of multivariate Logistic regression. Results: Among the 105 patients, the mean age was 74 (68, 77) years old. The incidence of frail and intermediate frail was 35.2% (37/105) and 29.5% (31/105), respectively. Multivariate logistic analysis showed statistically significant associations of frailty with age (OR=1.14, 95%CI:1.08-1.20, P<0.001), body mass index (OR=0.87, 95%CI:0.79-0.95, P=0.001) and the level of eGFR (OR=0.98, 95%CI:0.96-0.99, P=0.003) in those patients. The incidence of frail in patients with eGFR<45 ml·min(-1)·(1.73 m(2))(-1) and 45-59 ml·min(-1)·(1.73 m(2))(-1) was 1.02 (OR=2.02, 95%CI: 1.06~3.87) and 0.84 (OR=1.84, 95%CI: 1.05-3.22) times higher than that of eGFR≥60 ml·min(-1)·(1.73 m(2))(-1), respectively. Conclusion: The incidence of frailty in the elderly patients with CKD is affected by many factors, such as age, body mass index and renal function, and increases with decreased renal function.

Abstract
Objective: To investigate the role of lysosomes in manganese-induced toxicity in human neuroblastoma SK-N-SH cells. Methods: SK-N-SH cells were treated with MnCl(2) at doses of 0.062 5, 0.125, 0.25, 0.5, 1.0, 2.0 and 4.0 mmol/L for 24 h, and the cell viability was detected by MTT assay. Cells were treated with MnCl(2) at doses of 0.125, 0.25, 0.5 and 1.0mmol/L for 24 h, and lysosomes labeled with lysotracker red were observed by laser confocal microscopy, the expression levels of LAMP1 and CTSD were detected by western blot, and CTSD activity was detected by Cathepsin D Activity Fluorometric Assay Kit. Results: Compared with the control group, the survival rates of SK-N-SH cells were decreased significantly in the 0.5-4.0 mmol/L MnCl(2) treatment groups (P<0.01) , the relative fluorescence intensities of 0.5 and 1.0 mmol/L MnCl(2) treatment groups were increased (P<0.01) . Compared with the control group, the 0.125-0.5 mmol/L MnCl(2) treatment groups had significant increase in the the expression of LAMP1 (P<0.01) . Compared with the control group, the expression of m-CTSD was significantly increased at the does of 0.125-0.25 mmol/L MnCl(2), while it was decreased at the does of 1.0 mmol/L (P<0.01) . Otherwise, it wasn't observed significant difference of the activity of CTSD between different MnCl(2) treatment groups. Conclusion: MnCl(2) could cause cytotoxicity in SK-N-SH cells. Lysosomes may play a normal function at low doses of manganese, but they may be damaged at high doses of manganese. As an organelle that can degradate substrates in autophagy, lysosomes participate in the neurotoxic mechanism of manganese.

Abstract
OBJECTIVE Epstein-Barr virus associated gastric cancer (EBVaGC) is different from the traditional gastric cancer (Epstein-Barr virus non-associated gastric cancer, EBVnGC), and has unique clinicopathological features. This study investigated the largest single center cancer series so as to establish the clinicopathological and molecular characteristics of EBVaGC in China. METHODS A retrospective analysis was conducted on EBVaGC and EBVnGC patients diagnosed at Peking University Cancer Hospital from 2003 to 2018 by comparing their clinicopathological features and prognosis. The gastric cancer (GC) dataset of public database was analyzed to obtain differentially expressed genes. The expression of important genes and their association with prognosis of GC were verified in GC tissues from our hospital. RESULTS In this study, 3 241 GC patients were included, and a total of 163 EBVaGC (5.0%) patients were identified. Compared with EBVnGC, EBVaGC was higher in male and younger patients, and positively associated with remnant GC, poorly differentiated adenocarcinoma, and mixed type GC. EBVaGC was inversely related to lymph node metastasis. The 5-year survival rate of EBVnGC and EBVaGC was 59.6% and 63.2% respectively (P<0.05). In order to explore molecular features of EBVaGC, the Cancer Genome Atlas (TCGA) dataset was analyzed (n=240), and 7 404 significant differentially expressed genes were obtained, involving cell proliferation, apoptosis, invasion and metastasis. The down-regulated invasion/metastasis gene SALL4 and the up-regulated immune checkpoint gene PD-L1 were important molecular features of EBVaGC. Validation of these two genes in large GC series showed that the majority of the EBVaGC was SALL4 negative (1/92, 1.1%, lower than EBVnGC, 303/1 727, 17.5%), and that PD-L1 was mostly positive in EBVaGC (81/110, 73.6%, higher than EBVnGC, 649/2 350, 27.6%). GC patients with SALL4 negative and PD-L1 positive were often associated with better prognosis. CONCLUSION EBVaGC is a unique subtype of GC with less metastasis and a good prognosis. It also has a distinct molecular background. The down-regulation of invasion/metastasis gene SALL4 and up-regulation of immune checkpoint gene PD-L1 are important molecular features.

Abstract
Radiotherapy resistance remains the major factor limiting the radiotherapy efficacy in colorectal cancer. The Mre11-RAD50-Nbs1 (MRN) complex is known to play a critical role in the DNA double strand breaks (DSBs) repair pathways and thus facilitates radioresistance. Targeting MRN function can sensitize cancer cells to irradiation in some malignancies. In this study, we stably knocked down RAD50 protein in colorectal cancer (CRC) cell lines, HCT116 and DLD1, and evaluated their response to irradiation as well as the DSB repair dynamics. We observed that downregulation of RAD50 sensitized CRC cells to irradiation with reduction in DSB repair efficiency after exposure to irradiation. In addition, RAD50 was found to be upregulated in CRC cancerous tissue samples compared to non-cancerous adjacent tissues (NATs) and in patients who were resistant to RT. Elevated RAD50 expression was associated with poor patient survival in CRC. In conclusion, targeting RAD50 can serve as an efficient strategy to sensitize CRC cells to irradiation. RAD50 protein may be used as a biomarker for patient survival in CRC.

Abstract
Objective: The identification of neovascularization in carotid plaque in carotid artery stenosis by contrast-enhanced ultrasound (CEUS) provides other risk markers for stroke besides carotid artery stenosis -intraplaque neovascularization. Methods: From January 2017 to September 2017, 40 patients with carotid atherosclerosis plaque were examined by contrast-enhanced ultrasound in China-Japanese Friendship Hospital. The enhancement intensity (EI) measured by contrast-enhanced ultrasound was compared with the micro-vessel density (MVD) measured by histopathology after carotid endarterectomy (CEA). Contrast-enhanced ultrasound was used to observe whether there was enhancement in the plaque and the enhancement was divided into 0-2 grades. The EI in plaque, the ratio of EI in plaque to EI in carotid artery lumen were calculated by time intensity curve quantitative analysis software. Pathological sections of carotid plaques after CEA were stained with CD34 and neovascularization density was measured. Results: There were significant differences in age, EI1, EI1/EI2 and CD34 among patients with different grades of plaque enhancement (P<0.05), but no significant differences in gender and EI2 (P>0.05). The density of neovascularization obtained by CD34 staining was highly positively correlated with EI1 (r=0.836, P<0.001), EI1/EI2 (r=0.955, P<0.001), but not with age (r=0.066, P=0.684), EI2 (r=0.159, P=0.328). Conclusions: Contrast-enhanced ultrasound can observe the neovascularization in carotid plaque, which is a simple and non-invasive method to evaluate the stability of carotid plaque. CEUS may also help to extract features of vulnerable plaques, such as acute intraplaque hemorrhage.

Abstract
Objective: To investigate the protective effect of carbon monoxide releasing molecule 2 (CORM-2) on post-resuscitation myocardial dysfunction in rats. Methods: Forty male SD rats which were healthy were randomly divided into 5 groups: sham operated group(sham group), cardiopulmonary resuscitation(PCR) group, DMSO group, inactivated CORM-2(iCORM-2) group and CORM-2 group (n=8 each). Established the model of post-cardiac arrest myocardial dysfunction by intravenous potassium chloride (4 ℃) injection combined with asphyxiation for 4 minutes and then followed by artificial chest compression for 3 minutes. Sham group: rats were instrumented with catheter without inducing cardiac arrest and resuscitation, and intraperitoneal injection of 0.9% normal saline (4 ml/kg) was performed 12 hours before catheterization. CPR group: rats were instrumented with catheters and underwent CPR, and intraperitoneal injection of 0.9% normal saline (4 ml/kg) was performed 12 hours before surgery.CORM-2 group: rats were instrumented with catheters and underwent CPR, intraperitoneally injected the prepared CORM-2 solution (4 mg/kg) at 12 hours before surgery. DMSO group: rats were instrumented with catheters and underwent CPR, intraperitoneally injected the prepared DMSO solution (4 ml/kg) at 12 hours before surgery. iCORM-2 group: rats were instrumented with catheters and underwent CPR, iCORM-2 solution (4 mg/kg) was intraperitoneally injected at 12 hours before surgery. Hemodynamic data (MAP, +dp/dtmax, -dp/dt) were continuously monitored and recorded for 4 hours after resuscitation (or catheterization) in each group. Myocardial tissue specimen and blood samples were taken after resuscitation (or catheterization). The myocardial ultrastructure was observed by transmission electron microscope. Lactate dehydrogenase (LDH) activity was measured by lactate-pyruvate method. Serum creatine kinase isoenzyme (CK-MB) concentration was measured by ELISA. Western blot was used to detect the levels of Caspase-3, Caspase-9 and Cyt-C protein in myocardial tissue. Results: MAP, +dp/dtmax and -dp/dt at 0.5, 1, 2, 3 and 4 hours post resuscitation were significantly lower than those immediately after catheterization in CRP, DMSO, iCORM-2 groups (all P<0.05). MAP at 0.5, 1, 2, 3, and 4 hours post resuscitation were significantly lower in CRP, DMSO and iCORM-2 groups than those at respective time points in sham group (all P<0.05), while MAP was similar between CORM-2 group and Sham group at these time points (all P>0.05). +dp/dtmax and -dp/dt values at 0.5, 1, 2, 3, and 4 hours post resuscitation were lower than those at respective time points in sham group and significance was found at 0.5, 1 and 2 hours post resuscitation (both P<0.05), while +dp/dtmax and -dp/dt values were similar between CORM-2 group and sham group at various time points (all P>0.05). Myocardial ultrastructure, especially mitochondrial structural integrity was better preserved in the CORM-2 group than those in the other resuscitation groups at 4 hours after resuscitation. Serum LDH activity and CK-MB concentration were significantly elevated at 4 hours after resuscitation in the CPR group, DMSO group and iCORM-2 group than those in sham group (all P<0.01); CK-MB concentration was also higher in CORM-2 group than that in sham group,and LDH level was similar between CORM-2 group and sham group (P>0.05). Serum LDH activity and CK-MB concentrations were significantly lower in the CORM-2 group than those in the other resuscitation groups (all P<0.01). The myocardial expressions of Caspase-3, Caspase-9 and Cyt-C at 4 hours after resuscitation were significantly higher in the CPR group, DMSO group and iCORM-2 group than those in sham group; the myocardial expressions of Caspase-3 and Caspase-9 were significantly higher in CORM-2 group than those in sham group (both P<0.05), while Cyt-C expression was similar between CORM-2 group and sham group. The expressions of the above 3 proteins were significantly lower in the CORM-2 group than those in the other resuscitation groups (all P<0.05). Conclusions: CORM-2 can effectively alleviate post-resuscitation myocardial injury in rats with cardiopulmonary resuscitation and improve cardiac function. Protecting myocardial mitochondria and inhibiting mitochondrial apoptosis pathway may serve as the protective mechanisms in this model.

Abstract
Macrophage migration inhibitory factor (MIF) is pleiotropic cytokine that has multiple effects in many inflammatory and immune diseases. This study reveals a potential role of MIF in acute kidney injury (AKI) in patients and in kidney ischemic reperfusion injury (IRI) mouse model in MIF wild‐type (WT) and MIF knockout (KO) mice. Clinically, plasma and urinary MIF levels were largely elevated at the onset of AKI, declined to normal levels when AKI was resolved and correlated tightly with serum creatinine independent of disease causes. Experimentally, MIF levels in plasma and urine were rapidly elevated after IRI‐AKI and associated with the elevation of serum creatinine and the severity of tubular necrosis, which were suppressed in MIF KO mice. It was possible that MIF may mediate AKI via CD74/TLR4‐NF‐κB signalling as mice lacking MIF were protected from AKI by largely suppressing CD74/TLR‐4‐NF‐κB associated renal inflammation, including the expression of MCP‐1, TNF‐α, IL‐1β, IL‐6, iNOS, CXCL15(IL‐8 in human) and infiltration of macrophages, neutrophil, and T cells. In conclusion, our study suggests that MIF may be pathogenic in AKI and levels of plasma and urinary MIF may correlate with the progression and regression of AKI.

Abstract
Objective: To investigate the clinical features, laboratory characteristics and genetic diagnosis of Kabuki syndrome (KS). Methods: Between September 2014 and September 2016, seven children with clinically diagnosed KS from the neurology department, Beijing Children Hospital, Capital Medical University were included in this study. Three of them were male and 4 were female aged from 19 days to 6 years and 4 months with a median age of 3 years and 1 month. The clinical features, laboratory and imaging materials, gene tests were analyzed prospectively. Results: Clinical manifestation: cephalofacial anomaly: all seven cases had unusual facies presented as long palpebral fissures, eversion of the lateral third of lower eyelids, arched eyebrow with brow sparse, epicanthus, orbital hypertelorism, short columella with broad and depressed nasal tip; six cases presented with palatal arch deformity; four cases presented with ptosis; three cases presented with dental abnormalities and hearing impairment respectively; two cases presented with strabismus and earlap malformation respectively; one case presented with amblyopia. Six cases presented with skeletal anomalies. Six cases presented with dermatoglyphic anomalies. All cases presented with mild to moderate mental retardation. Three cases presented with short stature. Four cases presented with cardiac abnormalities. Three cases presented with epileptic seizures. Others: three cases presented with dystonia and neonatal hyperbilirubinemia respectively; two cases presented with feeding problem and hypoglycemia respectively; one case presented with micropenis and fetal finger pads respectively. All seven patients received magnetic resonance imaging (MRI) tests, and none demonstrated an abnormal finding. Five patients received electroencephalogram (EEG) tests, and three of them presented with seizures and EEG abnormalities. Five patients received genetic testing and all presented with KMT2D heterozygous mutations which were new mutations proved by parents validation (three cases were nonsense mutations, one was frameshift mutation, one was missense mutation). All patients received rehabilitation training and symptomatic treatments. Three patients presented with epileptic seizures received antiepileptic therapy. At a median follow-up of 11 months (from 4 months to 2 years), one patient died, one lost to follow-up and five had improved intellectual and physical development. Epileptic seizures were controlled or reduced significantly in three patients presented with epileptic seizures. Conclusions: KS is a multisystem disease with complicated manifestations, which needs a combination of various diagnosis and treatments. Genetic testing can help determine the diagnosis. Unusual facies and mental retardation are the main clinical features and diagnostic clue. It is important to improve prognosis through increasing the knowledge of KS, early diagnosis, and treatment.

Abstract
Objective: To investigate the clinicopathologic characteristics, diagnostic features and prognosis of primary renal neuroendocrine carcinoma (NEC). Methods: The clinicopathologic data of eight cases of renal NEC was collected from January 2008 to December 2017 from Affiliated Hospital of Qingdao University. Immunohistochemical staining was performed, and follow-up information was analyzed, and the relevant literature reviewed. Results: The patients' mean age at diagnosis was 45 years (range, 27-66 years); five were women, and three were men. The tumors located on the left side in five patients, and on the right side in three. Five cases were detected incidentally, and three patients presented with loin pain. Microscopically, these cases included five well-differentiated NECs (three carcinoids, two atypical carcinoids), two small cell NECs, and one large cell NEC according to the World Health Organization classification of 2016. The tumors infiltrated the renal capsule in six cases. Necrosis was found in five cases. Vascular invasion with tumor emboli was seen in three cases. Lymph node metastasis was identified in one case. Immunohistochemically, the expression rates of neuroendocrine markers CD56, chromogranin A (CgA) and synaptophysin (Syn) were 6/8, 4/8, and 8/8 respectively. Some of the NECs were positive for epithelial markers CKpan (6/8, with three cases showing focal positivity) and CAM5.2 (4/8) of variable degrees. The Ki-67 proliferation index was≤3% in the carcinoids; ≥50% in the small cell carcinoma and large cell carcinoma; and 5% and 8% for the two cases of atypical carcinoid, respectively. All cases were negative for EMA, CK7, CA9, CD10, CD117, PAX2, PAX8, WT1, p63, S-100 and TTF1. Three patients (two with small cell carcinoma and one with large cell carcinoma) died of extensive metastases at 3 months, 4 months and 9 months after operation, while five patients were well, without recurrence or distant metastasis for follow-up period of one to nine years. Conclusions: Primary renal NEC is rare. Carcinoid is the most common histological type. The pathomorphological features and neuroendocrine markers (CD56, CgA, Syn), epithelial markers (CKpan, CAM5.2) and nephrogenic markers (PAX2, PAX8) are important for the diagnosis. Renal carcinoid tumors are indolent and prone to early metastasis, but are associated with prolonged survival. The small cell renal cell carcinoma and large cell carcinoma are highly malignant renal tumors with poor prognosis and short survival.

Abstract
Objective: Using microarray technology, to research characteristic circRNA and miRNA expression profile of acute myocardial infarction (AMI), and then explore the role of these circRNA and miRNA in gene regulation. The aim is to explore the mechanism of development of AMI. Methods: The patients hospitalized in the Cardiovascular Research Center of the First Affiliated Hospital of Xinxiang Medical University between November 2016 and January 2017 were included and divided into control group and AMI group according to diagnostic criteria. We collected their whole blood and extracted the total RNA, and the expression profiles of circRNA and microRNA genes in peripheral blood of AMI were analyzed by gene chip. We predicted circRNA which was possible to combine with miRNA, and drew a network diagram, and the differentially expressed circRNA was analyzed by GO and Pathway. Results: There was difference in circRNA expression profile between the control group and the AMI group. The results showed: (1) a total of 1 670 circRNA had differential expressions, and in the analysis of miRNA expression, 13 miRNA had differential expressions (P<0.05, fc≥2); (2) multiple circRNAs-miRNAs were involved in the occurrence of AMI; (3) the analysis of GO and Pathway for differentially expressed circRNAs showed that many pathways, disease and function participated in it. Conclusion: CircRNA, as an important post transcriptional regulator, is closely related to the development of AMI with miRNA.

Abstract
Fluazinam is a pyridinamine fungicide that induces oxidative stress and mitochondrial damage in cells, and it has been reported to be neurotoxic. To characterize the biological effects of fluazinam, we assessed mitochondrial bioenergetics, dopamine system expression, and behavior of early life staged zebrafish (0.01 μM-0.5 μM). Fluazinam at environmentally-relevant levels did not induce sub-lethal effects in larvae, but at the LC50 (0.5 μM), fluazinam decreased basal and ATP-linked respiration significantly in embryos. As mitochondria are directly related to redox homeostasis and apoptosis, the expression of genes related to oxidative stress and apoptosis were measured. Superoxide dismutase 2 (sod2), heat stock protein 70 (hsp70), bcl2-associated X protein (bax), and caspase 9 (casp9) mRNA levels were up-regulated by 0.5 μM fluazinam. Taken together, there was evidence for mitochondrial dysfunction and oxidative damage at the highest concentration of fluazinam (0.5 μM) tested. As there are reports for fluazinam-induced neurotoxicity in dopamine synthesizing cells, transcriptional targets in the dopamine system were assessed in the zebrafish. Tyrosine hydroxylase 1 (th1) and dopamine receptor 2a (drd2a) mRNA levels were decreased by 0.5 μM fluazinam, suggesting that this fungicide may affect the dopaminergic system. To further assess the potential for fluazinam-mediated neuromodulation, the dark photokinesis response was assessed in larvae following exposure. Larvae exposed to 0.1 μM fluazinam showed hyperactivity, while larvae exposed to 0.2 and 0.3 μM showed hypo-activity. This study demonstrates that fluazinam disrupts mitochondrial bioenergetics in zebrafish, inducing an oxidative stress response, and aberrant behaviors in larvae that are dose dependent.

Abstract
Objective: To investigate the current status of reproductive health among the female medical staff in a provincial maternal and child health hospital and analyze the occupational influencing factors for reproductive health, particularly the effects of high-intensity work, work shift, chemical poisons, and physical and biological factors on reproductive health, and to provide a scientific basis for developing related intervention measures and promoting the reproductive health of professional females. Methods: A reproductive health questionnaire was designed in terms of age, type of work, professional title, education level, working hours, working strength, and the reproductive health of female staff to analyze the current status of reproductive health, working strength, and occupational hazardous factors. The female medical staff in the provincial maternal and child health hospital completed the questionnaire on the internal network of the hospital voluntarily. Results: Of all respondents, 19.46% had a history of miscarriage, 5.90% visited the hospital due to infertility, 21.31% had irregular menstruation within the last 3 months, and 30.57% had reproductive system disease; 72.28% of the investigated medical staff often worked at night, 47.25% often worked overtime (more than 3 days a week) , and 22.27% worked over 8 hours daily. The respondents who often worked overtime had a significantly higher prevalence of reproductive system disease than those who did not often work overtime (χ(2)= 58.65, P<0.01) . The respondents who often worked at night had a significantly higher rate of miscarriage than those who did not work at night (χ(2)=41.57, P<0.01) . In all respondents, 87.08% were often exposed to chemical injuries such as disinfectants, and 78.15% had contact with noise, radiation, and other physical injuries; the medical staff exposed to chemical and physical injuries had a significantly higher proportion of individuals with a history of miscarriage than the unexposed staff (χ(2)=10.04, P<0.01; χ(2)=13.30, P<0.01) . Conclusion: Much attention should be paid to the reproductive health of female medical staff in the provincial maternal and child health hospital, who have high working strength. The occupational hazard factors can be avoided by reasonably arranging the work schedule and creating a supportive environment to improve the reproductive health of female medical staff.

Abstract
OBJECTIVE To determine the effect of metformin and adiponectin on the proliferation of EC cells and the relationship between metformin and adiponectin. METHODS The proliferation impact of different concentrations of metformin and adiponectin on two types of EC cells ishikawa (IK) and HEC-1B was confirmed by CCK-8 method. qRT-PCR and Western blot were used to detect the effect of different concentrations of metformin on the changes of adiponectin receptors (AdipoR1 and AdipoR2) of the EC cells both in mRNA and protein level and the role of compound C, an adenosine monophosphate-activated protein kinase (AMPK) inhibitor, on the above effects. RESULTS (1) Both metformin and adiponectin could significantly promote the proliferation of endometrial cancer (EC) cells in a time and concentration dependent manner (P<0.05).(2)Metformin and adiponectin had synergy anti-proliferative effect on EC cells and the combination index (CI) value of IK cells was 0.906 34 and of HEC-1B cells was 0.827 65. (3)qRT-PCR was used to detect the mRNA levels of AdipoR1 and AdipoR2 after 5 mmol/L and 10 mmol/L metformin, respectively, stimulating IK and HEC-1B cells for 48 hours and the mRNA expressions of AdipoR1 and AdipoR2 were significantly increased when compared with the control group (0 mmol/L)(IK: AdipoR1 of 5 mmol/L and 10 mmol/L group: P<0.001,AdipoR2 of 5 mmol/L group: P<0.001; HEC-1B: AdipoR1 of 5 mmol/L group: P<0.001, 10 mmol/L group: P=0.023, AdipoR2 of 5 mmol/L group: P<0.001, 10 mmol/L group: P=0.024). When combined with compound C, the RNA levels of AdipoR1 and AdipoR2 were not different compared with the control group (0 mmol/L, P>0.05). (4) Western blot was used to detect the protein levels of AdipoR1 and AdipoR2 after 5 mmol/L and 10 mmol/L metformin, stimulating IK and HEC-1B cells for 48 hours and the protein level was significantly increased when compared with the control group (0 mmol/L)(IK: AdipoR1 of 5 mmol/L group: P=0.04, 10 mmol/L group: P=0.033, AdipoR2 of 5 mmol/L group: P=0.044, 10 mmol/L group: P=0.046; HEC-1B: AdipoR1 of 5 mmol/L group: P=0.04, 10 mmol/L group: P=0.049, AdipoR2 of 5 mmol/L group: P=0.043, 10 mmol/L group: P=0.035). When combined with compound C,the protein levels of AdipoR1 and AdipoR2 were not different compared with the control group (0 mmol/L, P>0.05). CONCLUSION We find that metformin and adiponectin have synergy anti-proliferative effect on EC cells. Besides, metformin can increase adiponectin receptors expressions of EC cells both in mRNA and protein levels and this effect is accomplished by the activation of AMPK signaling pathway.

Abstract
Objective: To improve the understanding of deep venous thrombosis (DVT), the present study was conducted to investigate the difference of DVT onset in hospitalized patients with different underlying diseases. Methods: This is a single-center retrospective study from Beijing Shijitan Hospital. Clinical data from hospital onset DVT patients from 2007 to 2016 were collected. DVT was confirmed with compression ultrasonography (CUS), color Doppler flow imaging (CDFI), CT venography (CTV), magnetic resonance venography (MRV), lower extremities radionuclide venography(RDV) or conventional venography (CV). The risk factors of DVT in hospital were analyzed with a Chi-square analysis. Results: A total of 5 063 patients (1.65%) with DVT involving 5 024 veins were identified from 305 922 inpatients admitted without DVT during ten years. Among DVT patients, 2 752 were males (54.36%) and 2 311 were females (45.64%) with age of (74.1±15.9) years (range from 1 to 103 years). Patients with DVT were elder and longer inhospital than those without DVT (P< 0.001). Patients with respiratory diseases had higher incidence of DVT (6.83%, OR= 5.498, 95%CI 5.151-5.868) than those with other system diseases, in which patients with respiratory failure had the highest incidence of DVT (9.53%, 95%CI 6.912-8.018) among all patients. The risks of having DVT were higher in patients with serious internal medicine diseases than those in patients with trauma, or cataclasis/operations, or invasive manipulations. Among all DVT patients, 71.54% of them were with inflammation diseases, 55.56% were with hypertension and 54.93% were with structural heart disease. DVT often occurred in inferior extremities (83.78%, 4 360/5 063) in patients irrespective of underlying diseases. Conclusions: There is an association between underlying diseases of hospitalized patients and the development of DVT. Patients with internal medicine diseases had higher risk to develop DVT than those with trauma or cataclasis/operations or invasive manipulations. To prevent the development of DVT, its screening should be emphasized in patients with serious internal diseases.

Abstract
Objective: To observe the outcomes of no necrotic cavity lavage after debridement and drainage in patients with infected pancreatic necrosis(IPN). Methods: From February 2014 to August 2017, there were 89 patients who were diagnosed as IPN undergoing minimally invasive surgery with no necrotic cavity lavage and large caliber-wide channel drainage in Department of General Surgery, Xuanwu Hospital, Capital Medical University. There were 57 male and 32 female patients aging of (49.5±14.4)years (ranging from 23 to 84 years). The body mass index of 89 patients was (25.4±3.8)kg/m(2) (ranging from 17.6 to 36.7 kg/m(2)). Among the 89 patients, 37 cases(41.6%) of biliary pancreatitis, 10 cases (11.2%) of alcoholic pancreatitis, 16 cases(18.0%) of hyperlipidemic pancreatitis, and 26 cases(29.2%) of other reasons. Results: Of 89 patients, IPN in 6 patients(6.7%) resolved using only percutaneous catheter drainage; another 83 patients underwent laparoscopic debridement(n=3, 3.4%) or video-assisted debridement(n=80, 89.9%). No patient was conversed to laparotomy. The average operation frequency and surgery time was (2.3±1.7) times and (56.5±31.7) minutes.The median bleeding volume and total length of stay was 10(0-600) ml and 34(6-172) days separately. The complication rate(Clavien-Dindo grade≥Ⅲ) was 9.0%(8/89) which involved mainly abdominal hemorrhage (5/8) and digestive tract fistula formation (3/8). The overall mortality rate was 6.7%(6/89). Among them, 3 cases died of abdominal infection, bacteremia and multiple organ failure, 2 cases died of pulmonary infection and bacteremia and 1 case died of fungal infection. Conclusion: No necrotic cavity lavage after debridement and drainage operation is considered effective and safe for IPN patients.

Abstract
Objective: To investigate the expression of BRD4 in squamous cell carcinoma (SCC) tissues and cells, and the effects of its expression on cell proliferation and invasion ability. Methods: Immunohistochemistry was used to detect BRD4 protein expression in SCC tissues and paired normal esophageal squamous epithelial tissues. The expression of BRD4 protein was detected in different SCC cell lines and normal esophageal squamous epithelial cells by Western blot. BRD4 siRNA and control siRNA were used to transfect SCC Eca109 cells, and experiments were divided into three groups: untreated group, control siRNA group and BRD4 siRNA group. Western blot was employed to investigate the expression of BRD4 protein in the three groups of SCC Eca109 cells. CCK-8 kit was utilized to detect cell proliferation ability, and Transwell chamber was used to examine cell invasion ability. Finally, Western blot was used to detect the expression of MMP2 and MMP9 proteins. Results: The positive rate of BRD4 protein expression in SCC tissues was significantly higher than that of normal squamous epithelial tissues. The expression of BRD4 protein in 4 SCC cell lines was higher than that in normal esophageal cell Het-1A. BRD4 siRNA obviously downregulated the expression of BRD4 protein in Eca109 cells, and its downregulation contributed to the suppression of cell proliferation and invasion ability in Eca109 cells (all P<0.05), coupled with the decreases of MMP2 and MMP9 proteins. Conclusion: BRD4 may be closely associated with the proliferation and invasion of SCC, and it thus may be a potential therapeutic target for SCC.

Abstract
A novel technique based on laser induced plasma imaging is proposed to measure residual pressure in sealed containers with transparent walls, e.g. high voltage vacuum interrupter in this paper. The images of plasma plumes induced on a copper target at pressure of ambient air between 10-2Pa and 105Pa were acquired at delay times of 200ns, 400ns, 600ns and 800ns. All the plasma images at specific pressures and delay times showed a good repeatability. It was found that ambient gas pressure significantly affects plasma shape, plasma integral intensities and expansion dynamics. A subsection characteristic method was proposed to extract pressure values from plasma images. The method employed three metrics for identification of high, intermediate and low pressures: the distance between the target and plume center, the integral intensity of the plume, and the lateral size of the plume, correspondingly. The accuracy of the method was estimated to be within 15% of nominal values in the entire pressure range between 10-2Pa and 105Pa. The pressure values can be easily extracted from plasma images in the whole pressure range, thus making laser induced plasma imaging a promising technique for gauge-free pressure detection.

Abstract
The division of stages on the formation and development of Mongolian medicine is a major issue on the history of Mongolian medicine. Based on Mongolian social, economic and cultural development and the characteristics of Mongolian medicine itself, Professor B. Jigmed creatively puts forward the three stages of development of ancient and modern times of Mongolian medicine. He also reasonably sorts out historical materials to comprehensively and systematically display the general picture of its development. This approach exerts great effect on restructuring the body of Mongolian medicine itself, unveils its rule of development, and promotes its disciplinary construction.

Abstract
Objective: To establish the immortalized mouse brain microvascular pericytes model and to apply to the cerebrovascular toxicants screening study. Methods: Brain pericytes were isolated from 3 weeks of mice by tissue digestion. Immortalized pericyte cell line was constructed by infecting with LT retrovirus. Monoclone was selected to purify the immortalized pericyte cell line. The pericyte characteristics and purity were explored by immunocytochemistry. Cell proliferation was measured by using the Pomega MTS cell Proliferation Colorimetric Assay Kit. Pericytes were treated with 0, 160, 320, 640, 1 280, 2 560 μmol/L lead acetate, 0, 5, 10, 20, 40, 80 μmol/L cadmium chloride and 0, 5, 10, 20, 40, 80 μmol/L sodium arsenite in 24 hours. Cell toxicity of each group was determined by MTS assay, median lethal dose (LD(50)) was calculated in linear regression. Results: Mouse brain pericytes were successfully isolated by tissue separation and enzyme digestion method. After immortalized by LT retroviruses, monoclone was selected and expanded to establish pericyte cell line. The brain pericytes exhibited typical long spindle morphology and positive staining for α-SMA and Vimentin. The proliferation of brain pericytes cell lines was very slowly, and the doubling time was about 48 hours. The proliferation of immortalized brain pericytes cell lines was very quickly, and the doubling time was about 24 hours. After lead acetate, cadmium chloride and sodium arsenite treatment for 24 hours respectively, gradual declines in cell viability were observed. The LD(50) of lead acetate was 2 025.0 μmol/L, the LD(50) of cadmium chloride was 36.6 μmol/L, and the LD(50) of sodium arsenite was 33.2 μmol/L. Conclusion: The immortalized mouse brain microvascular pericyte model is established successfully by infecting with LT retrovirus, and can be applied to screen cerebrovascular toxicants. The toxicity of these toxicants to immortalized mouse brain microvascular pericyte is in sequence: sodium arsenite,cadmium chloride, lead acetate.

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
We have recently noticed an accidental error in part of a figure which appeared in the above‑mentioned article. In Fig. 3A, the image for the HGC27‑pEF, 15 h panel was mistakenly replicated as the HGC27‑KD, 0 h panel in the same figure, and the AGS‑pEF, 15 h and AGS KD, 0 h panels were mistakenly switched with each other. We have reviewed the original files and the individual figures for the submitted composite figure, and realized that the error occurred when we produced the composite figure by marrying the individual images to the final figure. The same image was accidentally pasted twice without us being fully aware of the error. We have identified all the original images, and the corrected version of Fig. 3 is shown below. We regret that this error occurred, and thank the Editor for affording us the opportunity to publish this Corrigendum.

Abstract
Objective: To summarize the clinical and pathological features of small vessel-childhood primary angiitis of the central nervous system (SV-cPACNS), discuss the immune therapy and increase the attention to brain biopsy in SV-cPACNS. Methods: The clinical data, pathology of brain biopsy, treatment and outcome of an SV-cPACNS patient hospitalized in Beijing Children's Hospital in February 2016 were analyzed retrospectively. The cases reported at Pubmed, CNKI and Wanfang databases from 2007 to 2017 were searched, the clinical and pathological features, immunotherapy and prognosis of the disease were summarized according to the literature review. Results: A 70 months old girl had 6 times relapses during 5 months' disease course. Symptoms included convulsions, limb paralysis, blurred vision and speech difficulty. Multiple cortical lesions were found successively in brain MRI but CT angiography was negative. The pathology of brain biopsy revealed thickening of small vessel walls together with lymphocytic infiltration. After the treatment with rituximab, remission was achieved and remained stable without recurrence in 1 year follow up. A total of 44 pathologically confirmed cases reported in nearly 10 years were retrieved. Male to female ratio was 1∶3.5. The average onset age was 9.8 years. Clinical manifestations included seizures (37/45, 82%), headache (35/45, 78%), cognitive decline (28/45, 62%), speech regression(20/45, 44%), paralysis (15/45, 33%), and so on; 70% (19/27) patients experienced relapses. Erythrocyte sedimentation rate and C-reactive protein slightly elevated, antinuclear antibody and other autoimmune antibodies were mostly negative. Mild lymphocytosis in cerebrospinal fluid was found in 67%(29/43) patients. 53%(23/43) patients had elevated CSF protein level, several had elevated IgG and positive oligoclonal band. Bilateral multifocal lesions were revealed in 80% (36/45) brain MRIs, meanwhile all angiographies were unremarkable. The pathology showed small angiitis and immunohistochemistry positive for CD3 and CD20. Twenty-seven patients had detailed therapeutic information; 25 of them received immunosuppressive agents, including cyclophosphamide, mycophenolate mofetil and rituximab. One patient died, 26 patients achieved remission with 54% (22/44) had neurological sequelae. Conclusions: SV-cPACNS had varied clinical manifestations, there was no specificity in laboratory and imaging examination and angiography was often negative. The definite diagnosis relied on brain biopsy, which showed lymphocytic inflammation of small vessels. SV-cPACNS tended to relapse and induce neurologic deterioration. Treatment required long-term use of steroids and immunosuppressive agents. Rituximab could be an effective agent.

Abstract
The dipyridyl herbicide paraquat induces oxidative stress in cells and is implicated in adult neurodegenerative diseases. However, less is known about paraquat toxicity in early stages of vertebrate development. To address this gap, zebrafish (Danio rerio) embryos were exposed to 1, 10 and 100 μM paraquat for 96 h. Paraquat did not induce significant mortality nor deformity in embryos and larvae, but it did accelerate time to hatch. To evaluate whether mitochondrial respiration was related to earlier hatch times, oxygen consumption rate was measured in whole embryos. Maximal respiration of embryos exposed to 100 μM paraquat for 24 h was reduced by more than 70%, suggesting that paraquat negatively impacts mitochondrial bioenergetics in early development. Based upon this evidence for mitochondrial dysfunction, transcriptional responses of oxidative stress- and apoptosis-related genes were measured. Fish exposed to 1 μM paraquat showed higher expression levels of superoxide dismutase 2, heat shock protein 70, Bcl-2-associated X protein, and B-cell CLL/lymphoma 2a compared to control fish. No differences among groups were detected in larvae exposed to 10 and 100 μM paraquat, suggesting a non-monotonic response. We also measured endpoints related to larval behavior and dopaminergic signaling as paraquat is associated with degeneration of dopamine neurons. Locomotor activity was stimulated with 100 μM paraquat and dopamine transporter and dopamine receptor 3 mRNA levels were increased in larvae exposed to 1 μM paraquat, interpreted to be a compensatory response at lower concentrations. This study improves mechanistic understanding into the toxic actions of paraquat on early developmental stages.

Abstract
Non-small-cell lung cancer (NSCLC) patients who experience brain metastases are usually associated with poor prognostic outcomes. This retrospective study proposed to assess whether bevacizumab or gefitinib can be used to improve the effectiveness of whole brain radiotherapy (WBRT) in managing patients with brain metastases. A total of 218 NSCLC patients with multiple brain metastases were retrospectively included in this study and were randomly allocated to bevacizumab-gefitinib-WBRT group (n=76), gefitinib-WBRT group (n=77) and WBRT group (n=75). Then, tumor responses were evaluated every 2 months based on Response Evaluation Criteria in Solid Tumors version 1.0. Karnofsky performance status and neurologic examination were documented every 6 months after the treatment. Compared to the standard WBRT, bevacizumab and gefitinib could significantly enhance response rate (RR) and disease control rate (DCR) of WBRT (P<0.001). At the same time, RR and DCR of patients who received bevacizumab-gefitinib-WBRT were higher than those who received gefitinib-WBRT. The overall survival (OS) rates and progression-free survival (PFS) rates also differed significantly among the bevacizumab-gefitinib-WBRT (48.6 and 29.8%), gefitinib-WBRT (36.7 and 29.6%) and WBRT (9.8 and 14.6%) groups (P<0.05). Although bevacizumab-gefitinib-WBRT was slightly more toxic than gefitinib-WBRT, the toxicity was tolerable. As suggested by prolonged PFS and OS status, bevacizumab substantially improved the overall efficacy of WBRT in the management of patients with NSCLC.

Abstract
Objective: To investigate the prevalence and clinical characteristics of peripheral blood eosinophilia (EOS) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: From July 2014 to June 2016, AECOPD patients in the Department of Respiratory Medicine of Affiliated Hospital of Chengdu University, were retrospectively stratified into two groups according to two standards of eosinophilic exacerbations (the peripheral blood eosinophil count ≥2% or ≥3% on admission). Demography, clinical symptoms, laboratory results, length of stay, total hospitalization expenses, and defined daily expenses were compared between groups. Results: A total of 559 cases with AECOPD were finally recorded, the prevalence of eosinophilia was 43.1% (241 cases by EOS≥2%) and 27.2% (152 cases by EOS≥3%), respectively. According to either standard, there were no significant differences in sexes, age, course of disease (P>0.05), and there were no significant differences in global initiative for chronic obstructive lung disease (GOLD) grades, parameters of pulmonary function, modified british medical research council (mMRC) scores, rate of antibiotic use, systemic glucocorticoids administration, and average daily expenses (P>0.05). According to 2% standard, leucocytes, neutrophils, monocytes, hs-CRP were lower than non-eosinophilic patients [(5.9±2.0)×10(9)/L vs (8.2±4.0)×10(9)/L, (3.9±1.6)×10(9)/L vs (6.5±3.8)×10(9)/L, (0.446±0.169)×10(9)/L vs (0.501±0.276)×10(9)/L, (25.8±35.9) vs (46.2±55.6) mg/L, all P<0.01]; basophils, lymphocytes were higher than non-eosinophilic patients [(0.043±0.025)×10(9)/L vs (0.029±0.021) ×10(9)/L, (1.3±0.6) ×10(9)/L vs (1.1±0.6) ×10(9)/L, both P<0.01]; length of stay, total hospital expense were shorter (or lower) than non-eosinophilic patients [(10.6±5.0) vs (11.6±5.8) d, (11 851±7 491) vs (14 254±10 751) RMB, both P<0.05]. According to 3% standard, leucocytes, neutrophils, monocytes, hs-CRP were lower than non-eosinophilic patients (all P<0.05), and basophil were higher than non-eosinophilic patients (P<0.01), but no significant differences were observed in lymphocytes, length of stay and total hospital expense (all P>0.05). Conclusion: Eosinophilia is of relative high prevalence in AECOPD patients, and basophil in eosinophilic patients is higher than non-eosinophilic patients.

Abstract
The aim of this study was to detect the differential expression of Artemin (ARTN) and matrix metallopeptidase protein 9 (MMP-9) in endometrial carcinoma (EC) and to assess their clinical significance in order to provide insight into the pathological mechanism of tumor infiltration and metastasis in EC. A total of 48 patients who had undergone surgery for EC at the School of Medicine and Affiliated Hospital of HeBei University of Engineering between July 2015 and July 2016 were included in the study. The 48 patients were classified into 3 groups according to tumor stage: 27 patients with EC stage I, 12 patients with EC stage II and 9 patients with EC stage III. The samples collected from each patient included fresh normal endometrial tissue, endometrial simple hyperplastic tissue and endometrial atypical hyperplastic tissue. The transcription levels of ARTN and MMP-9 mRNA in each group were investigated using RT-PCR. The expression levels of ARTN and MMP-9 protein in each group were examined using Western blotting. Spearmans correlation analysis was used to analyze the correlation between the expression levels of ARTN and MMP-9 proteins and EC tissue type. RT-PCR and Western blotting assays revealed that the expression levels of ARTN and MMP-9 were increased in normal endometrial tissue, simple hyperplastic tissue, atypical hyperplastic tissue and EC of stages I, II and III. The differences noted were statistically significant (P less than 0.05). Furthermore, Western blot analysis indicated that the expression levels of ARTN and MMP-9 proteins in lymphatic metastatic tissues were higher than those in non-lymphatic metastatic tissues (P less than 0.05). The expression levels in the infiltration tissues of the deep muscular layer were higher than those noted in the light muscular layer (P less than 0.05). The expression levels of ARTN and MMP-9 proteins were positively correlated (P less than 0.05). The data suggest that ARTN and MMP-9 are involved in the occurrence, development, invasion and metastasis of EC, and play a synergistic role in the development of EC and lymphatic metastasis.

Abstract
To analyze the nursing effect on the respiratory function of thoracotomy patients, sixty thoracotomy hospitalized patients were studied. The subjects were divided into a normal group (A) and an observation group (B). The patients in group A received routine nursing only, while those in group B received chest physiotherapy as well as routine nursing. Afterwards, the respiratory function indicators of the two groups were compared and a data analysis was performed. The results showed that the partial pressure of oxygen (PO2) value of the patients in group B was greater than that of the patients in group A while the partial pressure of carbon dioxide (PCO2) value in group B was smaller than that in group A, and there was a significant difference between the two groups (p less than 0.05). The vital capacity under normal circumstances and forced breathing of group B were greater than that of group A and the difference was statistically significant (p less than 0.05). The incidence of complications (atelectasis, respiratory infections, pleural effusion) was statistically significant between the two groups (p less than 0.05). The degree of autonomic respiratory dysfunction in group B was lower than that in group A, and there was a significant difference (p less than 0.05), suggesting that the respiratory function in patients receiving chest physiotherapy improved significantly.

Abstract
Objective: To investigate the clinical value of albumin (Alb) in the diagnosis of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD). Methods: A retrospective analysis was performed for the clinical data of 90 children with NICCD who visited Children's Hospital of Fudan University from January 2007 to December 2014, and according to the content of Alb, these children were divided into Alb < 30 g/L (LA) group with 20 children and Alb ≥30 g/L (NA) group with 70 children. The clinical manifestations, results of laboratory examination, results of blood tandem mass spectrometry and urine gas chromatography-mass spectrometry, and gene detection results were compared between the two groups. The t-test and the chi-square test were used for statistical analysis.. Results: There were significant differences between the LA group and the NA group in splenomegaly degree (3.28±1.95 cm vs 1.92±1.06 cm, P = 0.030), aspartate aminotransferase/alanine aminotransferase ratio [3.15 (0.38-5.93) vs 2.14 (0.26-6.67), P = 0.010], activated partial thromboplastin time (53.27±11.68 s vs 45.06±9.79 s, P = 0.003), and international normalized ratio (1.92±1.35 vs 1.29±0.33, P = 0.001). The SLC25A13 mutation I 851_854del4 was associated with Alb (χ2 = 4.76, P = 0.025). Conclusion: As for the children with Alb < 30g/L who are highly suspected of having NICCD, SLC25A13 gene detection and blood/urine mass spectrometry should be performed as early as possible, in order to initiate intervention treatment as soon as possible, prevent and treat complications, and improve prognosis.

Abstract
Objective:To investigate if and when the mandarin speech perception ability deteriorates with age in adults with audiometrically normal hearing sensitivity.Method:The participant group included 75 normal hearing adults sampled from across the entire range of adulthood, of which there are 20 males and 55 femals. The participants were divided into 5 groups with 15 participants per age group: 20-30 years, 31-40 years, 41-50 years, 51-60 years, and 61-70 years. We applied speech perception test using Mandarin Hearing in Noise Test.Result:The speech perception scores were significantly different among the five groups in 0 dB and -5 dB conditions (P<0.001), but they weren't significantly different among the five groups in quiet, 10 dB and 5 dB (P>0.005).There was a significant negative correlation between speech perception and age in -5 dB conditions.Conclusion:When the background noise becomes more severe even for participants with audiomerically normal hearing, it was shown that speech perception declined with age.

Abstract
Chemicals show diverse modes of action (MOAs) in aquatic organisms depending upon acute and chronic toxicity evaluations. Here, toxicity data for Vibrio fischeri involving 52 compounds for acute and chronic toxicity were used to determine the congruence of acute and chronic toxicity for assessing MOAs. Using toxic ratios, most of the compounds categorized into MOAs that included baseline, less inert or reactive compounds with acute toxicity were also categorized as baseline, less inert or reactive compounds with chronic toxicity. However, significantly different toxic effects were observed with acute and chronic toxicity for the reactive and specific-acting compounds. The acute-chronic toxic ratios were smaller and less variable for the baseline and less inert compounds, but were greater and more variable for the reactive and specific-acting compounds. Baseline and less inert compounds share same MOAs, but reactive and specific-acting compounds have different MOAs between acute and chronic toxicity. Bioconcentration processes cannot reach an equilibrium for highly hydrophilic and ionized compounds with short-term exposure, resulting in lower toxicity compared to long-term exposure. Pronounced differences for the antibiotics were not only due to the difference in bioconcentration, but also due to a predicted difference in MOAs during acute and chronic exposures.
