Ten pregnant rats randomly chosen from the total twenty rats on day 9 ofprognancy were injected a high dosage of LRH-A.The other ten were used ascontrol group.After one day and two days the ultrastructure of the luteal cell wasobserved by transmission electron microscope.Compared with the control group,theexperimental group showed an increase of lipid droplets,and a lot of large lipiddroplets appeared.The smooth endoplasmic reticulum decreased,dissolved and lostits regular array.Mitochondria degenerated,Autophagocytic vacuole,lysosome,myelin figure,multivesicular body as well as residual body increased.Golgi appa-ratus swelled in the first day after injection,and then shrank.Microvilli on thesurface of the cell decreased.The above results all suggest that with the injection of high dosage of LRH-Ainto the pregnant rats,luteal cell shows morphologic regression and decrease insecretive function.

OBJECTIVETo examine the efficacy and safety of dual blockade of the renin-angiotensin-aldosterone system (RAAS) among patients with type 2 diabetic kidney disease.
DATA SOURCESWe searched the major literature repositories, including the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE, for randomized clinical trials published between January 1990 and October 2015 that compared the efficacy and safety of the use of dual blockade of the RAAS versus the use of monotherapy, without applying any language restrictions. Keywords for the searches included "diabetic nephropathy," "chronic kidney disease," "chronic renal insufficiency," "diabetes mellitus," "dual therapy," "combined therapy," "dual blockade," "renin-angiotensin system," "angiotensin-converting enzyme inhibitor," "angiotensin-receptor blocker," "aldosterone blockade," "selective aldosterone blockade," "renin inhibitor," "direct renin inhibitor," "mineralocorticoid receptor blocker," etc.
STUDY SELECTIONThe selected articles were carefully reviewed. We excluded randomized clinical trials in which the kidney damage of patients was related to diseases other than diabetes mellitus.
RESULTSCombination treatment with an angiotensin-converting enzyme inhibitor supplemented by an angiotensin II receptor blocking agent is expected to provide a more complete blockade of the RAAS and a better control of hypertension. However, existing literature has presented mixed results, in particular, related to patient safety. In view of this, we conducted a comprehensive literature review in order to explain the rationale for dual blockade of the RAAS, and to discuss the pros and cons.
CONCLUSIONSDespite the negative results of some recent large-scale studies, it may be immature to declare that the dual blockade is a failure because of the complex nature of the RAAS surrounding its diversified functions and utility. Further trials are warranted to study the combination therapy as an evidence-based practice.

Objective To observe the antihypertensive effect of indapamide combined with enalapril on spontaneously hypertensive rats(SHRs).Methods Forty SHRs were randomly divided into 4 groups: control,indapamide,enalapril,and indapamide+enalapril(n=10 in each group).Medicine in varied doses was given to rats by intragastric administration.Variations of weight,heart rate and blood pressure were measured. Results Varied doses of medicine did not exert significant effects to the weight and heart rate of SHRs during and after the administration.In indapamide+enalapril group,the pressure of SHRs was significantly decreased with varied doses compared to that before the administration(P

Abstract?AIM: To observe the effect of acute angle closure glaucoma with cataract patients treated with glaucoma trabeculectomy combined two incision phacoemulsification and intraocular lens ( IOL ) implantation ( two incision triple surgery) .?METHODS: Patients admitted in our hospital during Jan.2013 to Jan.2016.The acute angle closure glaucoma with cataract patients in 40 cases ( 58 eyes ) were randomly divided into two groups:the observation group of 20 cases ( 29 eyes ) with two incision triple surgery treatment, and the control group of 20 cases ( 29 eyes ) with single incision triple after treatment.Visual acuity, intraocular pressure, bleb, corneal endothelial cell density, the area at 1mo before and after surgery, and postoperative complications of two groups were analyzed.?RESULTS: Postoperative visual acuity of two groups were significantly improved, but there was no significant difference between groups ( P >0.05 ); postoperative intraocular pressure, bleb formation rate of the observation group were 14.41 ±1.38mmHg, 90%, and the control group 14.40 ±1.40mmHg, 86% without statistical significance ( P>0.05 ), corneal endothelial cell density and area of observation group after 1mo were 1696.6±300. 8/mm2 , 540.8±71.6μm2 , and control group 1410.6±288.5/mm2 and 594.3 ±72.8μm2 with significant differences ( P<0.05).The incidence rate of compli-cation was 17%in the observation group, and 21%in control group (P>0.05).?CONCLUSION: For patients with acute angle closure glaucoma and cataract given two incision triple surgery and single incision triple surgery treatment can get good outcomes, but the effect of double incision on corneal endothelial cell injury is less.

Objective To assess the safety and efficacy of the transohturator tape (TOT) for surgical treatment of female stress urinary incontinence (SUI). Methods Clinical data of 206 TOT procedures for female urinary incontinence from Jan 2007 to Dec 2009 was retrospectively analyzed.Thirty-one women were identified as having mixed stress urinary incontinence.The mean age was 54.29 years(range,32-81 years),themean disease coursewas 10.31 years (range,1-40 years),and the mean follow-up time was 17.3 months (range,3-39 months).Therapeutic effects were assessed by Grouts-Blaivas outcome score.The results of the operation,complications and changes of urodynarnics were observed. Results The TOT operations were conducted under local anesthesia.The mean operative time was 23.9 min (range,16-35 min),Mean blood loss was 17.8 ml(range,15-30 ml).Short-term complications were as follows:thigh pain 14.08%,dysuria 5.83%,urinary posture change 0.97% and urinary retention 0.49%.The long-term complication rate was 0.97%,including vaginal wall defect and tape exposure in one case:the burr of tape exposure and sex life influence in one case.Long-term symptoms disappeared completely in 202 cases.The cure rate was 98.06%,and the rate of satisfaction was 100%. Conclusions Our results demonstrate that TOT procedure is a minimally invasive,safe and effective surgical treatment for stress urinary incontinence.
