Objective To observe the effect and safety of Ginkgo biloba extract (EGb) in patients with chronic allograft nephropathy (CAN),and to study the clinical protective mechanism of EGb.Method A prospective,non-randomized,controlled study was conducted on 103 cases of CAN from March 2013 to March 2015.All patients were divided into experimental group (group A,53 cases) and control group (group B,50 cases).The group A was treated with EGb.Patients were followed up for at least 6 months.Before and after treatment,the changes in renal hemodynamic parameters were observed.The biochemical parameters were also observed,including 24-h urinary protein,urinary albumin,serum creatinine (Scr),triglyceride (TG),total cholesterol (TC),estimated glomerular filtration rate (eGFR),platelet count (PLT),fibrinogen (FIB),D-dimer (DD),activated partial thromboplastin time (APTT).The clinical efficacy and safety were analyzed.Result (1) Therewere no significant differences in clinical and biochemical parameters between the two groups before treatment (P＞0.05).(2) After treatment,the systolic peak flow velocity (Vmax) of segmental artery and arcuate artery in the experimental group was significantly higher than in the control group,and the resistance index (RI) in the experimental group was significantly lower than that in the control group,P＜0.05.(3) In both two groups,the 24-h urinary protein,urinaryalbumin,TG,TC and Scr were decreased after treatment (P＜0.05),and eGFR was elevated (P＜0.05).Moreover,the changes in 24-h urinary protein and urinary albumin in the experimental group were more significant than the control group after treatment (P＜0.05).(3) PLT,FIB and DD in experimental group were significantly decreased after treatment,and APTT was increased significantly (P＜0.05).PLT,FIB,DD and APTT had significant change after treatment in the experimental group as compared with control group.(4) There were no significant differences in adverse reactions between two groups (x2 =0.047,P =0.828).Conclusion The therapy of EGb in patients with CAN could reduce urinary protein and improve hypercoagulable state,and had few adverse reaction with good security.

Objective To analyze the clinical value of ovarian surgery in the treatment of primary ovarian mucinous carcinoma patients with fertility requirements.Methods 51 cases with fertility requirements with primary ovarian mucinous carcinoma who received surgical treatment were analyzed.The postoperative serum follicle stimulating hormone (FSH) and luteinizing hormone (LH),estradiol (E-2),anti Mullerian hormone (AMH) were deteced.The patients were followed up for 3 years,the survival rate and fertility were observed.Results Of 51 patients underwent surgery,postoperative 7d,14d,the FSH,LH levels in serum were higher than before operation (F=24.198,21.554,all P<0.05),E-2,AMH,PSV values were lower than before operation (F=24.407,35.028,11.064,all P<0.05).During the follow-up period to June 2015,there were 4 patients died of tumor recurrence,2 patients were lost to follow-up,45 patients survived,the survival rate was 88.23%.Of 45 patients survived,41 patients were normal menstrual cycle,menstruation,menstrual cycle 26-31 d,average (28.2±2.2)d;4 patients with irregular menstruation.Married women in the follow-up of 44 cases,including 28 patients with successful pregnancy,the pregnancy rate was 63.64%,there were 4 cases of spontaneous abortion,pregnancy in 3 patients because of abortion,pregnancy examination found 17 cases of abnormal pregnancy,4 cases of premature delivery.Conclusion In patients with primary ovarian mucinous carcinoma,it is feasible to use fertility preserving function,and the pregnancy rate is high,but the follow-up and monitoring should be strengthened to avoid the bad prognosis.

Objectives:To investigate the characteristics of clinical changes during maintenance therapy of chronic periodontitis.Methods:22 patients with chronic periodontitis were enrolled in a 9-month maintenance care program after non-surgical periodontal therapy.Oral hygiene instructions together with supra-and sub-gingival scaling and root planing were carried out every 3 months.Clinical parameters including probing pocket depth(PPD),probing attachment level(PAL),and bleeding on probing(BOP) were recorded at baseline and each re-examination point.Results:The mean PPD decreased by 0.44 mm,PAL increased by 0.38 mm and BOP point number decreased by 18.94%.The recoveries were mainly observed during the first 3 months.Sites with ≥4 mm pocket at baseline exhibited a greater percentage of pocket deepening than those with initial shallow pocket.The incidence of the sites with PPD deeping of posterior teeth increased more than that of anterior teeth(P

0.05 statistically,and we believe that the method of multiple micro-sampling has no effect on detecting the iron and element contents in VH samples of the died rabbit.

72h), the average deviations are over 15 hours. The average deviations of Equation 2 are almost all above 10 hours. The average deviations of Equation 3 are the lowest of the three.Conclusion The [K~+] and [Mg~(2+)] in the vitreous humor rises while the PMI extends. There are correlations between the concentration of K~+ and Mg~(2+) in the vitreous humor and the PMI. For the estimation of PMI, we suggest that the equation with R2 lower than 0.98, or with high average deviations should not be used. It seems that multiple regression equation could increase the accuracy of PMI estimation.

Objective:To study the dissolution behavior of panax notoginseng saponins R1 , ginseng saponin Rg1 and ginseng sapo-nin Rb1 in Xuesaitong soft capsules in two different dissolution media. Methods:The dissolution test conditions were confirmed accord-ing to“quality of medical drugs information set” of Japan and the dissolution media were chosen in accordance with the physicochemi-cal properties of Xuesaitong soft capsules, the in vitro dissolution of Xuesaitong soft capsules was inspected respectively in pH 6. 8 phosphate buffer and water. The dissolution rate was determined by HPLC-ELSD, and the similarity of the release curves for the three components was compared with similarity factors ( f2 ) method. Results: The assay displayed a good linearity over the concentration range of 0. 8-16. 0 mg·L-1(r=0. 999 6), 3. 0-60. 0 mg·L-1(r=0. 999 8) and 4. 0-80. 0 mg·L-1(r=0. 999 7) for panax notog-inseng saponins R1 , ginseng saponin Rg1 and ginseng saponin Rb1 , respectively. In pH 6. 8 phosphate buffer and water, f2 of ginseng saponin Rg1 and ginseng saponin Rb1 were both above 50 when compared with panax notoginseng saponins R1 . Conclusion:The meth-od is simple, accurate and reproducible in the dissolution determination of the soft capsules. The dissolution of ginseng saponin Rg1 and ginseng saponin Rb1 has similar characteristics with that of panax notoginseng saponins R1 in Xuesaitong soft capsules.

Objective To study the effects of norepinephrine (NE) on intracellular reactive oxygen species (ROS) production in cardiac myocytes and receptor pathways involved in ROS production. Methods DCFHDA fluorescent probe was used for the assessment of NE induced intracellular ROS production in cultured cardiac myocytes of the neonatal rats. Myocytes were exposed to NE, NE + prazosin, NE + propranolol, and NE + prazosin + propranolol at different time and doses. The changes of fluorescence intensity in cells were measured by flow cytometry. Results NE increased myocyte ROS production in time and dose dependent manners. NE induced ROS production was partially inhibited by prazosin or propranolol, and completely inhibited by prazosin and propranolol together in myocytes. Conclusion NE can induce intracellular ROS production in cultured cardiac myocytes of the neonatal rats in time and dose dependent manners through the mediation of both ? and ? adrenoceptors.

Objective To observe the ultrastructural changes of Candida albicans by the effect of oyster antibiosis protein which was extracted from muscle of oyster.Methods The colonies of candida albicans exposed to oyster antibiosis protein for 24 hours,with a blank control group and the differences of their ultrastructure were studied under electron microscope.Results After affected by oyster antibiosis protein for 4h,the cell walls were lacked and had reductus with pyknotic cytoplasm.16 hours later,most cells became global shape and their cytomatrix components were lost and some vacuoles appeared in the cytoplasm.24 hours later,the cell walls depleted and the cells spitted.Conclusion oyster antibiosis protein affected commendably the function of candida albicans.
