Objective To investigate the effect ofglycesylated hemoglobin(GHbA,c) on tissue-type plasminngen activator (t-PA)and level of serum plasminogen activator inhibitor-1 (PAI-1) in patients with early diabetic nephropathy (DN).MethodNinety patients with early DN from April 2004 to May 2005 were divided into 3 groups according to the level of GHbA1c,which was respectively less than 7% (group A),between 7% and 9% (group B),and more than 9% (greup C).Thirty healthy adults were chosen as control group.The levels of serum GHbA1c,t-PA and PAI-1 were detected on empty stomach in the morning.Results The level of serum t-PA was lower,the activity of PAI-1 was higher in groups of DN than those in control group (P＜0.05 or＜0.01),and those were changed with the level of GHbA,c.There were significant differences between group C and group A[t-PA:(0.14± 0.06),(0.28± 0.11) U/ml; PAI-1 (3.25 ±1.01),(1.90q± 1.09) U/ml](P＜0.05).Conclusions The fibrinolytic system exists unbalance in patients with early DN.Continuous hyperglycemia in patients with early DN make unbalanced fibrinolytic system more serious.Controlling the level of GHbA1c strictly can play an important role in delaying DN progress.

Objective To compare the application of Goldman , CARPREG and ZAHARA in predicting cardiac outcomes in pregnant women with congenital heart disease. Methods A retrospective analysis of 144 pregnant women with CHD , enrolled in The Third Affiliated Hospital of Guangzhou Medical University between Jan 1992 and June 2015 was conducted. The mortality and the incidence of cardiac events were counted by three risk estimation methods. The sensitivity and calibration of three systems were compared by using Hosmer-Lemeshow goodness of-fit analysis and Aera Under Curve (AUC). Results In terms of mortality rates, the sensitivity of CARPREG was higher than that of Goldman (AUC:0.874 and 0.889 respectively;P = 0.568 >0.05);. In terms of the incidence of cardiac events, the sensitivity of ZAHARA was higher than that of Goldman (AUC:0.912 and 0.773 respectively;P = 0.063 > 0.05); Conclusions All 3 risk estimation methods have good performance in sensitivity of predicting the incidence of cardiac events and mortality in pregnant women with CHD. The ZAHARA has a better calibration in predicting the incidence of cardiac events , and we recommend ZAHARA as the first choice of evaluation system for this kind of patients.

80%)as a calcium supplement.Methods Weanling SD rats(21 days after birth,n=50)were fed with low calcium forage for 10 days,then were divided into 5 groups randomly with 10 rats in each group,half male and half female.GroupⅠwas control group fed on low calcium forage.GroupⅡ~Ⅲ were fed on low calcium with L-lactic acid calcium.Group Ⅳ~Ⅴ were fed on low calcium forage with ultramicro-mussel shell powder.The experiment period was 4 weeks.The indices were including the eventual weight and length of the rats,the calcium absorption rate of calcium supplement,the concentrations of serum calcium,serum phosphorus,bone calcium,skeletal muscle calcium,myocardial calcium,hemocyte calcium,liver calcium,kidney calcium and the activity of alkaline phosphatase were assessed.Results The effect of ultramicro-mussel shell powder group was similar to L-lactic acid calcium.Conclusion The ultramicro-mussel shell powder can be well absorbed and utilized,and it can be used as a calcium supplement.

The metabolism study of radiolabeled drugs plays an important role in the development of new drugs. It provides information on drug absorption, metabolism, tissue distribution and excretion, and plays an irreplaceable role in the metabolite safety evaluation and mass balance of new drugs. The new guidance draft on clinical trials of radiolabeled drugs recently released by the US FDA puts forward higher standards and has been widely concerned by the industry. In recent years, in the research and development of new drugs in China, ¹⁴C labeled drugs have been used to carry out clinical metabolism studies, which has overcome key technical bottlenecks and accumulated experience. This paper summarizes the above research progress, analyzes the existing problems, and preliminarily looks forward to the future technological development and application.

Objective To study the clinical characteristicsand perioperative managementof complicated placenta increta, effectively reduce the maternal adverse perinatal outcomes. Methods Retrospective analysis 25 cases of complicated placenta increta between January 2013 and December 2015 in the Third Affiliated Hospital Of Guangzhou Medical University. Grouped into preoperative line 9 cases of ureteral catheter group and without catheter group 16 cases; Conventional hysterectomy group of 17 cases and the posterior hysterectomy group of 8 cases , compare the operation time , postpartum hemorrhage , blood transfusion amount , bladder injury or ureteral injury rate , rate of transferred to the ICU and hospital stay. Results 76% appear repeatedly painless vaginal bleeding during pregnancy , 56% appear bleeding before delivery. Prenatal diagnosis of 17 cases (68%). The preoperative line cystoscopy + bilateral retrograde ureteral catheter or after the posterior hysterectomy , shorter operation time , less postpartum hemorrhage , reduce blood transfusion volume , no urinary tract injury rate, transferred to the ICU rate is low, the difference was statistically significant (P < 0.05). Conclusions We should attach importance to repeated painless vaginal bleeding , improve prenatal diagnostic rate of complicated placenta increta. The perioperative managementis more comprehensive , effective and standard participation , preoperative ureteral catheter and the posterior hysterectomy can effectively reduce the maternal adverse perinatal outcomes.
