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 study the syndrome of inappropriate ADH secretion(SIADH)after all ogeneic hematopoietic stem cell transplantation(allo-HSCT)and the possible etiology.Methods SIADH was occurred in one patient with acute lymphoblastic leukemia who received secondary haploidentical stem cell transplantation after graft failure following umbilical cord blood transplantation.Results An 11-year-old boy was diagnosed as high-risk acute lymphoblastic leukemia,and the transplantation of unrelated double umbilical cord blood was performed for the first time,however,there was no engraftment at 28 days after the first transplantation.Secondary haploidentical stem cell transplantation was administered at day 33 after the first transplantion.The bone marrow and the peripheral blood stem cells from the patient's father transplantation was adopted.Pre-engraftment syndrome was developed in the patient at day 7 after secondary haploidentical HSCT followed by severe hyponatraemia(lowest serum sodium 115.8 mmol/L),natriuresis,hypo-osmolality of plasma,and twitch at day 26 after allo-HSCT.Then SIADH was diagnosed.The clinical condition was improved after restriction of water and administration of hypertonic saline,and eventually SIADH was controlled completely.By now,the patient had lived free of disease more than one year,with a normal diet and serum sodium in normal ranges.Conclusions SIADH after allo-HSCT is a rare fatal acute complication of central nervous system,whic h are probably associated with numerous transplant-related causes.Early accurate diagnosis and treatment promptly are great importance.

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.
