Objective To study the effect of follicle stimulating hormone(FSH)on the secretion of anti-mullerian hormone(AMH)in granulosa cells in patients with polycystic ovarian syndrome(PCOS).Methods From Aug.2008 to Dec.2009,33 patients with PCOS in Reproductive Medicine Research Center,Sixth Affiliated Hospital of Sun Yat-sen University were collected from 8-10 mm antral follicles and classified into the following three groups: FSH-unstimulated granulosa cells(unstimulated group,n =12),exogenous FSH-stimulated granulosa cells(exo-stimulated group,n =12)and internal FSH-stimulated granulosa cells(int-stimulated group,n =21).ELISA and real-time PCR were relatively used to measure protein and mRNA level of AMH.Luciferase reporting vector was constructed to detect the promoter activity of AMH.Results The levels of AMH secretion in PCOS granulosa cells were(11.4 ± 4.0)μg/L in unstimulated group,(7.9 ± 1.1)μg/L in exo-stimulated group and(5.6 ± 1.7)μg/L in int-stimulated group.Both the external and internal stimulation of FSH may suppress AMH secretion significantly(P ＜0.05).The mRNA level of AMH in PCOS granulosa cells were 2.5 ± 1.2 in unstimulated group,which were higher than 1.5 ± 0.5 in exo-stimulated group and 1.1 ± 0.7 in int-stimulated group significantly(P ＜0.05).The luciferase activity of AMH in PCOS granulosa cells were 11.5 ± 2.3 in unstimulated group,8.7 ± 2.4 in exo-stimulated group and 6.8 ± 2.4 in int-stimulated group.The luciferase activity of AMH in unstimulated group was significantly higher than those in exo-stimulated and int-stimulated groups(P ＜0.05).Conclusion FSH may inhibit the excessive secretion of AMH and stimulate follicle growth in PCOS granulosa cells by suppressing activity and expression of promoter.

[Summary] Traumatic brain injury ( TBI ) constitutes a major health and socioeconomic problem throughout the world . Increasing traffic accidents and aging of population promote the incidence of TBI .In patients with severe TBI mortality and disability rates are higher .And survivors may suffer physical activity , cognitive and psychological problems due to trauma , leading to shortened life span and higher risk of death than general population .They are also facing with long-term care and rehabilitation .This article reviewed the status and limitations on treatment of severe traumatic brain injury and its clinical significance .

AIM: To investigate the effects of oral administration of Astragalus membranceus, mung bean and arsenolite on the toxic of the arsenolite induced rats and the possible mechanisms with metallothionein (MT). METHODS: All the rats were oral administration with arsenolite. The Astragalus membranceus and mung bean were compared with the cadmium chloride which induced MT synthesis. The contents of MT were determined by cadmium saturation method, the liver mRNA levels for MT 1, MT 2 were detected by RT PCR. The protective effects of renal and liver were observed by testing alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCR). RESULTS: The contents of MT were accorded with the mRNA expression of MT 1, MT 2. Arsenolite, Astragalus membranceus and mung bean could induce the synthesis of MT, but the contents of MT which arsenolite induced were trace. The contents of MT significantly increased after oral administration of Astragalus membranceus and mung bean, especially in the Astragalus membranceus group (P

ObjectiveTo observe the morphological changes of enteric nerve-interstitial cells of Cajal (ICC) network in rats with the bacterial peritonitis, and to investigate the main cause of gastrointestinal dysfunction and gastrointestinal failure with the bacterial peritonitis. Methods Sixty Wistar rats of both sexes were randomly divided into two groups. The model of the bacterial peritonitis was established.To record the frequency and amplitude of slow wave in myoelectricity of intestine in vivo to assess the function of the intestine motility. The proximal 10.0 cm segment of jejunum beginning 2 cm distal to the pylorus from each group was studied using c-Kit and vesicular acetylcholine transporter (VAChT)/ neuronal nitric oxide synthase (nNOS) immunohistochemical double-staining with whole-mount preparation technique and laser scanning confocal microscopy(CLSM). Results Compared the result of the bacterial peritonitis group with the normal group, it was found that the frequency and amplitude of slow wave in myoelectricity of intestine of the bacterial peritonitis group were slower and lower than the normal group, CLSM scanned ICC network showed that compared with the control group, the distributions and densities of ICC of intestine in the bacterial peritonitis group decreased significantly(P<0.01), the number of ICC synapse decreased, the cell junction between ICC and the ICC network was disrupted, and the fluorescence intension of cell decreased. CLSM scanned enteric nerve-ICC network indicated that compared with the control group, in the bacterial peritonitis group, the distributions and densities of cholinergic nerves (P<0.01)/ nitrergic nerves(P<0.01)and ICC(P<0.01)of intestine significantly decreased respectively, the cell junction between enteric nerve and enteric nerve -ICC network was disrupted, and the fluorescence intension of enteric nerve -ICC network decreased. The network of cholinergic/nitrergic nerve-ICC was disrupted. Conclusion The number of cholinergic nerves and nitrergic nerves were reduced, and the enteric nerve-ICC network was damaged in rats with bacterial peritonitis. Gastrointestinal motility dysfunction can be caused by the bacterial peritonitis.

This study aims to compare the urate-lowering response rate of febuxostat and allopurinol in gout patient using a model-based meta-analysis. The literature search identified 22 clinical trials of gout with a total of 43 unique treatment arms that met our inclusion criteria, and a total of 6 365 gout patients were included in the study. The response rates of allopuriol and febuxostat were characterized by Tmax model and Emax model respectively, and the effect of baseline serum uric acid (sUA) and patient type on the drug effect was tested. The results showed that allopurinol can reach an average maximum response rate of 50.8% while febuxostat can reach a 100% response rate within a very short time, and the ED50 was 34.3 mg. Covariate analysis revealed that baseline sUA has a negative effect on response rate of allopurinol, and a positive effect on the predicted ED50 of febuxostat. For patients who had shown inadequate response to prior allopurinol treatment, the average response rate was about half that of the allopurinol responder patients.
