PURPOSE: Growth hormone(GH) receptors have been detected in Sertoli cells and clinical observations suggested the involvement of GH action(either indirectly via IGF-I or directly) on testicular function. This study is aimed at assessing the effect of GH on cell death during Sertoli cell culture. METHODS: Sertoli cells(TM4, mouse, male, ATCC, USA) were cultured by using DMEM(Dulbecco' Modified Eagle' Medium, Biowhitteker, USA) and Fetal Bovine Serum(10%, GIBCO BRL, USA) with or without human recombinant growth hormone(Eutropin, LGCI, Korea) of different concentrations(10, 50, 100, 500 microgram/mL of media), in 34degress C, 5% CO2 incubator. After cultivation during 5 days, Sertoli cells were examined under light microscope(x400). RESULTS: Number of survival Sertoli cell was remarkably increased in the GH treated(50 microgram/mL in media) group(62.6+/-12.4) compare to control(22.4+/-4.8)(P<0.05). Degree of survival Sertoli cell was increased proportionaly until 50 microgram/mL in concentration of GH in media, but decreased in higher than it. CONCLUSION: GH has the protective effect on death of Sertoli cell and it depends on GH concentration.

AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.

Objective To investigate the expression of phosphatidylinositol 3-kinase(PI-3K)in adipose tissue of polycystic ovary syndrome patients(PCOS),and explore molecular mechanisms of insulin resistance(IR)in PCOS.Methods Samples from patients with PCOS with IR(n=19),PCOS without IR (n=10)and controls(n=15)were collected.Serum fasting insulin(FIN)and fasting plasma glucose (FPG)were measure& Insulin resistance index was calculated using homeostasis model assessment (HOMA)to analyze the relationship between these markers and IR.Western blot technique was used to detect the PI-3K p85 subunit.Gene expression of PI-3K p85 subunit was detected by reverse transcription polymerase chain reaction(RT-PCR)method.Kinase activity was detected by immunoprecipitation,thin- layer chromatography and gamma scintillation counting.Results(1)The levels of FIN[(25.2?3.8) mU/L]and HOMA-IR(1.6?0.3)in PCOS with IR were significantly higher than those in PCOS without IR[(13.4 +3.8)mU/L,0.9?0.3]and controls[(9.5 +2.6)mU/L,0.5?0.3;all P＜0.05).(2) There was no significant difference in the protein(0.65?0.10)and gene expression(0.92?0.12)of PI-3 K p85 subunit in PCOS with IR compared with PCOS without IR(0.72?0.10,1.01?0.10)and control groups(0.73?0.14,1.00?0.12;P＞0.05).(3)PI-3K activity in PCOS with IR(81%)and PCOS without IR(89%)was significantly decreased(P＜0.01,P＜0.05)and negatively correlated with HOMA- IR(r=-0.69,P＜0.01;r=-0.62,P＜0.05).Conclusions No significant difference in the protein and gene expression of PI-3K p85 subunit in PCOS with IR is found.The decreased PI-3K activity may lead to IR of PCOS.

BACKGROUND: The key point in the treatment of acute cerebral infarction lies in inproving the blood supply of brain effectively as soon as possible as well as rescue ischemic and half diazonal nerve cells, so as to contract the local of infarction as great as possible.OBJECTIVE: To observe the effect of traditional treatment of cerebral piamatral microcirculation in gerbil with cerebral ischemic reperfusion injury by supplementing qi and activating blood circulation.DESIGN: Contrast animal experiment at random.SETTING: Zhabei Branch of Shanghai Changzheng Hospital.MATERIALS: The experiment was performed in the Institute of Naval Medicine (key laboratory of the whole army). Twenty-two healthy Monglian gerbils of clean grade (six months old) were selected and randomly divided into medicine group and control group with 11 gerbils in each group.METHODS: Animals were routinely anaesthetized and fixed in prone position to open the cranium window in median line and expose the pia mater. The cranium window was protected by being covered with a cotton ball containing artificial cerebrospinal fluid (ACSF) after operation. Gerbils were fixed in dorsal position with an median incision made in the lateral cervical nucleus to isolate and expose bilateral common carotid artery (CCA). The bilateral CCA were occluded by atraumatic micro-bulldog clamp, and the occluded blood flow in the distal end was observed under the microscope. Thirty minutes after occlusion of bilateral CCA, the vascular clamp was unclamped to recover the cerebral blood reperfusion. Gerbils in the medicine group were abdominally injected with 0.4 mL of Huangqi injection (containing 0.8 g of crude drug), 0.3 mL of compound Danggui injection (containing Danggui, Chuanqiong and Honghua, 0.09 g for each)and 0.3 mL of Danshen injection (containing 0.45 g of Shengyao). Animals in the control group were abdominally injected with same-volume of normal saline. The changes of pial microcirculation were quantitatively observed in two groups through cranium window respectively before blockage, at the reperfusion after blockage as well as in 120 minutes after injection by laser microcirculation microscope and the TV video system.MAIN OUTCOME MEASURES: The changes of piamatral microcirculation as well as comparison in venous blood flow velocity in gerbils of each group before and after ischemic reperfusion.RESULTS: All gerbils were involved in the analysis of results with no animal died in the experiment.①When the CCA of animals in the two groups were blocked, obvious contraction of piamatral microcirculation was seen and partial blood vessels were blocked up. Platelet and red blood cells etc.adhered to the arteriolae of grade Ⅰ and veinules below grade Ⅲ with microthrombus formed and large ischemic area appeared. The blood flow rate was obviously slowed down. Moderate and severe aggregations were found in red blood cells, and the white blood cells were significantly increased.There was obvious exudation in the periphery of microvessels. After CCA reperfusion, the arteriolae and veinule were in different thickness, and the thrombus in veinule of grade Ⅰ and Ⅱ formed in the cerebral ischemia were difficult to be removed by blood flow. Red blood cell moderately aggregated, and the number of white blood cells greatly increased. White small thrombus could be seen sometimes, while the exsudation in the periphery of microvessel was not significantly ameliorated. Great changes were found in gerbils of the medicine group after abnormal injection of supplementing qi and activating blood circulation medicine: almost all arteriolae and venulae were opened, and the rate of blood flow was accelerated with the blood flow rate remarkably increased. Deposit in the venulae began to decreased, and the thrombus was gradually dissolved. Red blood cells were moderately aggregated or normal. Blood flow in ischemic spot was improved significantly than that after reperfusion. The exudation in the periphery of microvessels was gradually lessened even dissolved. However,no obvious change was found in gerbils of the control group. ②The blood flow rate of arteriole in the medicine group was 1.04-1.50 mm, which was obviously higher than that in the control group with significant differences (P ＜ 0.5-0.01).③The blood flow rate of veinule in the medicine group was 0.96-1.12 mm/s, which was remarkably higher than that in the control group with marked differences (P ＜ 0.05-0.01).CONCLUSION: The effect on piamatral microcirculation of gerbil with cerebral ischemic reperfusion by supplementing qi and activating blood is exact, which is directly related with accelerated blood flow rate, expanded veinule and arteriolae as well as ameliorated blood-supply of brain.

AIM:To analyze the effect 17?-estradiol on activated macrophages and possibility of being a target of screening drugs for endometriosis. METHODS: Using scanning electron microscope, the surface of macrophages was observed. Nitric oxide (NO) in supernatant was determined by Griess's reagent. TNF-? was measured by MTT via L929 cells. Using Fluo-3/AM, i was measured by laser scanning confocal microscopy (LSCM). RESULTS: (1) Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17?-estradiol treated macrophages. (2) 17?-estradiol induced NO release from peritoneal macrophages. (3)The more TNF-? was made by macrophages under the induction of 17?-estradiol. (4)Intracellular Ca 2+ elevated 39.8% in peritoneal macrophages after 17?-estradiol (100 nmol/L) treatment. CONCLUSIONS: Macrophages were activated by 17?-estradiol at a certain concentration. Activated macrophages by 17?-estradiol may participate in endometriosis and may be a target of screening drugs for endometriosis.

Objective To investigate radionuclide imaging and routine CT in diagnosing hepatic focal nodular hyperplasia (FNH) and the combined diagnostic value of the two modalities. Methods Thirty-two patients with hepatic FNH were retrospectively studied. All patients underwent routine CT scan. Twenty-four patients were examined by 99Tcm-sulfur colloid (SC) hepatic planar scintigraphy and SPECT/CT imaging, and then patients who had abnormal foci underwent 99Tcm-diethyl iminodiacetic acid (EHIDA) triple-phase hepatobiliary imaging. x2 -test of four-table or Fisher exact probabilities in 2 × 2 table was applied for statistical analysis. Results Of all 32 patients pathologically diagnosed as FNH with single solitary nodule, 25 were classified as classic type and the rest 7 as non-classic type. Although routine CT found all hepatic lesions, only 15 cases were diagnosed pathologically as FNH classic type but the rest were either misdiagnosed or left as indeterminate. On radionuclide imaging (hepatic colloid scintigraphy plus triple-phase hepatobiliary images), 11 patients with big foci (with maximal diameter ＞3 cm) out of 24 patients were correctly diagnosed as FNH, with 7 diagnosed as classic type FNH and 4 as non-classic. Other 13 patients were either misdiagnosed or simply missed. The diagnosing rates of routine CT and radionuclide imaging were60.0% (15/25) and 38.9% (7/18) for FNH classic type, 0/7 and 4/6 for non-classic type,50.0% (10/20) and 73.3% (11/15) for big foci, 41.7% (5/12) and 0/9 forsmall foci (with maximal diameter≤3 cm), respectively. The total diagnosing rate of radionuclide imaging combined with routine CT was significantly higher than that of routine CT or radionuclide imaging alone ( x2 = 4. 48, P ＜ 0. 05;x2 =4.27, P ＜0.05 ). Conclusion Radionuclide imaging in combination with routine CT may improve the diagnostic accuracy for hepatic FNH patients.
