1.Progress of transforming growth factor beta/bone morphogenetic protein pathway and genetic mechanisms of pulmonary arterial hypertension
International Journal of Pediatrics 2016;43(8):593-597
Pulmonary arterial hypertension is the result of a variety of heart,lung disease and finally leads to right heart failure and death.Pulmonary arterial hypertension is characterized by the progressive increasing of artery pressure and the gradually increasing of pulmonary vascular resistance,and its pathogenesis has not been fully elucidated.Recent studies have found that transforming growth factor beta/bone morphogenetic protein pathway plays an important role in pulmonary arterial hypertension.The research about transforming growth factor betal bone morphagenetic protein pathway provides a new theoretical basis for the prevention and treatment of pulmonary arterial hypertension.This review focuses on progress of transforming growth factor beta/bone morphogenetic protein pathway and genetic mechanisms of pulmonary arterial hypertension.

The pathogenesis of children's primary nephrotic syndrome has not been completely clear at present.In the past few years,The polymorphism of these genes,such as angiotensin-converting enzyme gene,apolipoprotein E gene,platelet-activating factor acetylhydrolase gene,human histocompatibility leukocyte antigen gene,glucocorticoid receptor gene and cytokine gene,ect have been discovered that were significantly correlated with susceptibility,pathological progress,steroid response,disease recurrence and prognosis of primary nephrotic syndrome.This article reviewed the research progress of PNS and gene polymorphism.
3.Risk factors analysis of diabetic ketoacidosis combined with elevated serum amylase
Chinese Journal of Diabetes 2017;25(9):812-816
Objective To investigate the clinical risk factors of diabetic ketoacidosis (DKA ) combined with elevated serum amylase(AMS). Methods Totally 263 patients with DKA were enrolled in our study. They were divided into 2 groups according to the level of AMS:DKA with normal AMS (DKA,n=188);DKA with elevated AMS(HAMS,n = 75 ). HAMS patients then were divided into two subgroups according to the diagnosis with acute pancreatitis(AP)(HAMS+ AP,n = 25 )and without AP (HAMS,n = 50 ). TG,FPG and AMS were measured and analyzed with univariate analysis and multivariate analysis. Results HAMS group patients had a ratio of 28.5% with elevated AMS and 9.5% with AP.HAMS group had higher FPG,TG,HbA1 c,Na+ ,osmolality,BUN and Scr than DKA group(P <0.05).The levels of FPG,TG,osmolality,BUN and the time of CO2 CP recovery in HAMS+AP subgroup were all significantly higher than those in HAMS patients without AP (P < 0.05 ). Correlation analysis showed that HAMS was positively correlated with TG,FPG,Na+ ,Osmolality and BUN(P <0.05).Logistic regression analysis showed that hypertriglyceridemia was the independent risk factor of DKA combined with HAMS(OR 1.244,P <0.01),and was the independent risk factor of DKA combined with AP(OR 1.211,P <0.05). Conclusion Hypertriglyceridemia is the related risk factor of DKA combined with HAMS and AP. This study provides a theoretical basis to early screen patients with hyperamylasemia in DKA.
4.Comparison of the effect of acarbose, metformin and glipizide on newly diagnosed young type 2 diabetic patients
Chinese Journal of Endocrinology and Metabolism 2001;0(05):-
Ninty-four newly diagnosed young type 2 diabetic patients were treated by acarbose, metformin or glipizide for 36 weeks. The results showed that these drugs had similar effects in reducing blood glucose. Acabose decreased postprandial insulin secretion and had higher safety and better compliance. It was appropriate to use in newly diagnosed young type 2 diabetic patients.
5.Relation of FCM DNA content and S-phase fraction to the biological characteristics of lung cancer
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
Objective To investigate the relation of DNA content and SPF to the clinicopathological characteristic in lung cancer.Methods Fresh specimens taken from 56 patients with lung cancer and 36 patients with non-malignant pulmonary lesions were measured for DNA index(DI),S-phase fraction(SPF) by using FACSCalibur 4200 flow cytometry.Results ① DNA index(DI) of lung cancer was 1.18?0.33,0.99?0.07 in lung cancer and non-malignant groups,respectively.The percentage of heteroploid was 78.6% in lung cancer,(5.6%) in non-malignant.DI and the positive rate of heteroploid were significantly higher in lung cancer groups than that in non-malignant group(P0.05);③ It was demonstrated that SPF was significant higher in lung cancer groups than that in non-malignant group. The SPF of heteroploid tumors was higher than that of diploid tumors(P

8.Study on Bioequivalence of Domestic Oxcarbazepine Dispersible Tablets
China Pharmacy 2005;0(18):-
OBJECTIVE: To study the bioequivalence of domestic oxcarbazepine dispersible tablets. METHODS: 20 healthy male volunteers were randomly given oxcarbazepine dispersible tablets (test tablet) and oxcarbazepine tablets (reference tablet) via p.o. The plasma concentration of active metabolite (MHD) of oxcarbazepine were determined by HPLC. 3p97 software was used to calculate pharmacokinetic parameters and the bioequivalence of oxcarbazepine were evaluated. RESULTS: After treatment main pharmacokinetic parameters of test tablet vs. reference tablet were as follows: Cmax(4.231?0.841) ?g?mL-1 vs. (4.350?0.861) ?g?mL-1; tmax(4.13?0.43) h vs. (4.28?0.44) h; t1/2(14.17?2.66) h vs. (14.44?2.09) h; AUC0~60 (113.00?22.25) mg?h?L-1 vs. (118.11?14.20) mg?h?L-1; AUC0~∞(126.35?20.94) mg?h?L-1 vs. (130.54?16.17) mg?h?L-1. The relative bioavailability of test tablet to reference tablet was (95.67?12.80)%. CONCLUSION: Two kinds of tablets were bioequivalent.
9.Efficacy of pioglitazone combined with insulin in the trea tment of type 2 diabetes mellitus:a meta-analysis of randomized controlled trials
Chinese Journal of Endocrinology and Metabolism 2015;(7):608-610
The efficacy and safety of pioglitazone in combination with insulin in type 2 diabetic patient were evaluated. CENTRAL, MEDLINE, EMBASE, CBM, CNKI(up to September 2014) were searched by computer. The quality of included randomized controlled trials(RCTs)was assessed according to the Cochrane Collaboration system review, and then meta-analysis was performed using Stata 12. 0. A total of 9 RCTs were included. The results of meta-analyses showed that HbA1C value was lower in the group taking pioglitazone plus insulin than in the group taking insulin without pioglitazone[standard mean difference -0. 48, 95% CI( -0. 55, -0. 40),I2 = 0. 0% ,P = 0. 531], but there were more patients with hypoglycaemic in the pioglitazone plus insulin groups than with insulin without pioglitazone[relative risk 1. 33, 95% CI(1. 21, 1. 46), I2 =75. 4% , P=0. 00].
10.Differences between clinical and imaging standardized resident training method in ultrasound department
Chinese Journal of Medical Education Research 2015;14(6):619-622
The standardized resident training is an important and necessary way to cultivate high-quality medical talents.The goals between clinical and imaging residents in standardized training of ultrasound department are different.For clinical residents,the purpose is to understand the ultrasound images of various common diseases,combine clinical manifestation with ultrasound images,and improve the level of clinical diagnosis and treatment.For imaging residents,the goal is much higher and stricter;they need to master solid ultrasonic knowledge,independent operational and diagnostic ability,in order to provide reliable and accurate ultrasonic diagnosis.We individually design the teaching plan and methods in ultrasound department,in order to improve teaching efficiency and quality.
