Objectives To investigate the clinical features of progressive familial intrahepatic cholestasis type 2 (PFIC2) and to illustrate the importance of genetic diagnosis. Methods The mutations in 27 exons of ABCB11 encoding bile salt export pump (BSEP) were identiifed using polymerase chain reaction (PCR) and direct DNA sequencing in 6 children with suspected PFIC2. The pathogenicity of the newly identiifed mutations were predicted by SIFT, PolyPhen-2, SNPs&GO software. The clini-cal features and laboratory examinations were reviewed. Results Four disease-causing mutations, p.R928*, p.E554K, p.R575Q and p.Y337H were identiifed, and the last three mutations were novel. These three kinds of novel mutations can cause the disease. Two children with genetic diagnosis had such manifestations as onset within a month after birth, jaundice, hepatosplenomegaly, upset, increased levels of total bilirubin and direct bilirubin, GGT<100 U/L and high levels of total bile acid. Conclusions Genetic diagnosis is a potent tool for clinical diagnosis of PFIC2.

Objective To investigate the role of hypoxia-inducible factor-1α/ hexokinase Ⅱ (HIF-1α/HKⅡ) signaling pathway in the inhibition of hypoxia/reoxygenation (H/R)-induced apoptosis in the rat cardiomyocytes by hypoxic preconditioning (HPC).Methods Primarily cultured cardiomyocytes obtained from the neonatal rats were seeded in culture dishes at the density of 5× 105cells/ml.The cardiomyocytes were attached to the wall for 72 h and then randomly divided into 6 groups (n=15 each) using a random number table:control group (group C);group H/R;group HPC;HIF-1o inhibitor YC-1 group (group YC-1);group HPC + YC-1;dimethyl sulfoxide (DMSO) group.The ceils were exposed to D-Hank solution saturated with 95% N2 and 5% CO2 for 4 h,and then cultured in the normal culture atmosphere for 2 h.The cells in YC-1 and DMSO groups were incubated in the culture medium containing 10 μmol/l YC-1 and 0.1% DMSO (100 μl) for 24 b,respectively.HPC was induced by 3 cycles of 10 min hypoxia followed by 30 min reoxygenation,and H/R injury model was then established in group HPC.In group HPC+YC-1,the cells were incubated for 5 min in the M199 culture medium supplemented with 10 μmol/L YC-1 and 10% fetal bovine serum,and the other treatments were similar to those previously described in group HPC.After the end of treatments,the apoptosis in cardiomyocytes was detected by TUNEL,the expression of HIF-1α,HKⅡ and cytochrome c was detected by Western blot,and the mitochondrial membrane potential was quantitatively measured using fluorescence.Apoptotic rate was calculated.Results Compared with group C,the apoptotic rate was significantly increased,the mitochondrial membrane potential was significantly decreased,and the expression of HIF-1α,HKⅡ and cytochrome c was significantly up-regulated in group H/R (P<0.05).Compared with group H/R,the apoptotic rate was significantly decreased,and the mitochondrial membrane potential was significantly increased,and the expression of HIF-1αt and HKⅡ was significantly up-regulated,and the expression of cytochrome c was significantly down-regulated in group HPC (P<0.05).Compared with group HPC,the apoptotic rate was significantly increased,the mitochondrial membrane potential was significantly decreased,the expression of HIF-1α and HKⅡ was significantly down-regulated,and the expression of cytochrome c was significantly up-regulated in group HPC+YC-1 (P<0.05).Conclusion The mechanism by which HPC inhibits H/R-induced apoptosis in rat cardiomyocytes is associated with activation of HIF-1α/HKⅡ signaling pathway.

Objective To compare changes in indexes and analyze their values in prognosis of severe burn patients with sepsis.Methods A retrospective analysis was conducted. The patients with severe burn sepsis admitted to the Third Affiliated Hospital of Soochow University from August 2014 to December 2016 were enrolled. The blood culture was positive in the clinical diagnosis of sepsis. According to the prognosis, the patients were divided into death group and survival group. Their general information, vital signs, blood routine examination, serum sodium (Na+), serum glucose (Glu), C-reactive protein (CRP) and arterial partial pressure of carbon dioxide (PaCO2) at the time of admission and diagnosis of sepsis as well as the level of serum procalcitonin (PCT) at admission, diagnosis of sepsis and 1-8 days of post diagnosis were also compared. Receiver operating characteristic curve (ROC) was used to analyze the prognostic value of each index, and multivariate Cox regression analysis was used to analyze the influence of each index on the survival time, and the survival curve of Kaplan-Meier was analyzed for dead patients.Results There were 25 cases of severe burn patients with sepsis, which were admitted to hospital within 12 hours after injury; the time of diagnosis of burn sepsis was (14±6) days; 8 cases of survival; 17 cases died, the mortality rate was 68.0%, the time from diagnosis of sepsis to death was (28±14) days. The age of the death group was significantly higher than that of the survival group (years: 41±12 vs. 29±9,t = 2.598,P = 0.016), but there was no significant difference in the gender, total burn area,Ⅲ degree area, and the time of diagnosis of sepsis between the two groups. The platelet count (PLT) at the diagnosis of sepsis in death group was significantly lower than that of the survival group (×109/L: 69±43 vs. 180±108,t = -2.773, P = 0.023), and the PCT at 1-8 days of post-diagnosis in the death group was significantly higher than that of survival group [μg/L: 4.4 (2.2, 9.0) vs. 1.6 (0.7, 2.3),Z = -2.521,P = 0.012], but there was no significant difference in body temperature, heart rate, white blood cell count (WBC), percentage of neutrophils (Neu), Na+, Glu, CRP, PCT, PaCO2 at the time of admission and diagnosis of sepsis and PLT at the time of admission between the two groups. ROC curve analysis showed that the area under ROC curve (AUC) of age, PLT at the time of diagnosis and PCT at 1-8 days of post-diagnosis of sepsis was 0.808, 0.779, 0.825, respectively, for predicting the prognosis of patients with severe burn sepsis (allP < 0.05). At the cut-off age of 32, the sensitivity was 73.3% and the specificity was 75.0%. As the cut-off of PLT was 138×109/L at the time of diagnosis, the sensitivity was 92.3% and the specificity was 75.0%. As the cut-off of PCT was 2.39μg/L at 1-8 days of post-diagnosis of sepsis, the sensitivity was 73.3% and the specificity was 87.5%. Multivariate Cox regression analysis showed that age and PLT at the time of diagnosis were the favorable factors for the survival time of patients with severe burn sepsis (β value were -1.834, -0.029, respectively, bothP < 0.05). Kaplan-Meier survival analysis for patients in the death group showed that the median survival time of patients ≥32 years old was longer than that of patients < 32 years old (days: 32 vs. 9); 18-day cumulative survival rate was significantly higher than that of patients < 32 years old [83.3% (10/12) vs. 25.0% (1/4),χ2 = 9.705,P = 0.003].Conclusion Age, PLT at diagnosis of sepsis and PCT at 1-8 days after diagnosis of sepsis could be used as prognostic indexes for severe burn patients with sepsis.
