Objective To investigate the mutations of CLCNKB gene in a family with classic Bartter syndrome. Methods Genetic DNA was extracted from peripheral blood leucocytes of family members.The coding exons and intron exon junctions of CLCNKB gene were amplyfied by PCR and sequenced directly.Fifty unrelated healthy subjects were selected to exclude the possibility of polymorphism. Results A heterozygous(missense)mutation(482T>G,L161R)was detected in the exon 4 of patients.The hetemzygous mutation(L161R)was found in the mother,while no mutation was found in the father of this family.L161R had not been reported and was a novel mutation when referring to literatures and human genomic database home and abroad.Conclusion A new CLCNKB gene mutation(L161R)is identified for the first time.

Objective To evaluate the effect of early non-liquid diet for patients with mild acute pancreatitis by using Meta-analysis. Methods The randomized controlled trials(RCT) on early non-liquid diet intake for patients with mild acute pancreatitis were collected by computer searching the database of China National Knowledge Infrastructure(CNKI),Wanfang Periodical Database,CBM,Elsevier Scien Direct, cochrane library and PubMed from inception to February 2017, and analyzed by RevMan 5.2 software. Results Five RCTs were included in the study.The Results of Meta-analysis revealed that both the length of hospitalization after eating [MD=-1.48,95%CI-2.50~-0.47, P=0.004] and the total length of hospitalization[MD=-1.99,95%CI-(0.99-2.99),P=0.0001]in liquid diet group were less than that of non-liquid diet group,and the differences were statistically significant.There was no significant difference in the rate of the pain recurrence[RR=1.21,95%CI 0.77-1.91,P=0.40]and the rate of the elimination of oral feeding[RR=1.02,95%CI 0.45-2.30,P=0.96]because of pain,nausea or vomiting after refeeding,although all that rate in non-liquid diet was not lower than that of liquid diet group. Conclusions compared with liquid diet,early non-liquid diet intake for mild acute pancreatitis can shorten their hospitalization time, and it cannot be concluded that the non-liquid diet will increase the pain recurrence rate, and most patients have a better tolerance to non-liquid diet,and non-liquid diet can promote rehabilitation.

Objective:To analyze the clinical characteristics and risk stratification of 182 patients with acute pulmonary embolism (APE), and to investigate the correlation of neutrophil (N)/lymphocyte (L) ratio (NLR) and risk stratification/prognosis.Methods:The clinical data of 182 APE patients admitted to Peking University People’s Hospital from January 2015 to March 2021 were retrospectively collected, including age, sex, symptoms and signs, blood pressure, blood gas analysis, blood routine parameters, cardiac biomarkers, coagulation parameters, and right ventricular imaging parameters. The patients were divided into groups according to the risk stratification at admission and prognosis in hospital. χ2 test, t test or nonparametric test were used to analyze the differences in clinical characteristics, blood routine parameters, blood gas analysis, coagulation parameters and other parameters between the groups. Multivariate logistic regression analysis was used to study the independent risk factors for the prognosis of APE. Results:Among the 182 patients, 79 were male and 103 were female, 23 were in the high-risk group, 51 were in the intermediate-high-risk group, 46 were in the intermediate-low risk group, and 62 were in the low-risk group. There were 27 deaths and 155 survivors. The respiratory rate of the high/intermediate-high-risk group was significantly higher than that of the low/intermediate-low-risk group. Compared with the other three groups, pH, oxygen partial pressure (PO 2) and blood oxygen saturation (SO 2) in the high-risk group were significantly lower ( both P<0.05). There were statistically significant differences in WBC, N, and NLR levels between the high/intermediate-high-risk group and low/intermediate-low-risk group ( both P<0.05). However there were no significant differences in PLT, PLT/MPV, PLT/PDW, and coagulation related parameters PT, FIB, APTT and D-D between groups (all P > 0.05). MPV and PDW were only significantly different between the low-risk group, intermediate-low-risk group and high-risk group ( both P<0.05). Multivariate logistic regression analysis showed that NLR ( OR=1.179,95% CI:1.029-1.410, P=0.039) and PH ( OR=1.156,95% CI:1.031-1.522, P=0.041) were independent predictors of in-hospital mortality. The ROC curve was used to analyze the predictive value of NLR for in-hospital mortality. When the cutoff value of NLR was 8.38, the AUC of NLR was 0.824 (95% CI: 0.829-0.913), the corresponding sensitivity was 0.831, and the specificity was 0.887. Conclusions:NLR is correlated with risk stratification and prognosis of APE, and is an independent risk factor for poor prognosis.
