Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

Objective To assess the proficiency of water monitoring laboratory at rural, county, and provincial levels in Guangdong province, to ensure the province's drinking water monitoring results accurate and reliable. Methods State quality of certified reference materials as water arsenic, fluoride and chloride of 90 copies each were numbered and distributed to 90 monitoring laboratories in the province for testing, The measurement results of the participatory labs were evaluated through normative values and expanded uncertainty, and were compared with those of robust statistics method. Results All participatory labs had timely feedback of their measurement results. The qualified rate was higher when arsenic was tested by hydride generation atomic fluorescence spectrometry and zinc-new silver salt of sulfuric acid spectrophotometric system, while fluoride and chloride by ion chromatography. The average qualified rates of water arsenic, fluoride and chloride of the province's rural drinking water quality monitoring laboratory were 66% (59/90), 72% (65/90) and 72% (65/90), respectively.Seven participatory labs failed the proficiency testing of all three analytes and unqualified rate was 7.8% (7/90)among the ninety participated monitoring labs. The qualified rates of robust statistics method for arsenic fluoride and chloride were greater than those evaluated by the expanded uncertainty, and large deviations with small sample sizes. Conclusions The testing ability of drink-water monitoring labs in Guangdong province has improved.However, by comparison with the requirements of national quality control and testing skills, there is still a gap. It is suggested that internal quality control be included in routine inspeetion to improve laboratory testing technology.

OBJECTIVETo observe the effect of pure total flavonoids from Citrus (PTFC) on the hepatic fatty degeneration, inflammation, oxidative stress and SIRT1/PGC-1alpha expressions in mice with non-alcohol steatohepatitis (NASH), and discuss the action mechanism of PTFC on NASH.
METHODMice were given high-fat diet for 16 weeks to induce the NASH model. Since the seventh week after the model establishment, the mice were intervened with 100, 50 and 25 mg x kg(-1) x d(-1) PTFC for 10 weeks. The pathologic changes in hepatic tissues were observed with HE staining. The contents of TG, CHOL in hepatic tissue, as well as the levels of AST, ALT in serum were detected by using the biochemical process. The expression of SIRT1, PGC-1alpha and MnSOD mRNA in hepatic tissues were detected with Real-time PCR assay. SIRT1, PGC-1alpha protein and 8-OHdG expressions were determined with the immunohistochemical method. The SOD level in hepatic tissues was tested by the xanthine oxidase method. The MDA content in hepatic tissues was examined by the thiobarbituric acid method.
RESULTThe contents of TG, CHOL, NAFLD activity scores and ALT level in serum in hepatic tissues of mice in the model induced by fat-rich diet were obviously higher than that of the normal group (P < 0.010. The SIRT1, PGC-1alpha, MnSOD mRNA and protein expression in hepatic tissues were significantly lower than that of the normal group (P < 0.01). The expression of 8-OHdG and the content of MDA in hepatic tissues were obviously higher than that of the normal group (P < 0.01). After the intervention with different doses of PTFC, the NAFLD activity scores, the content of TG and the level of AST in serum were notably lower than that of the normal group (P < 0.01, P < 0.05); whereas the SIRT1, PGC-1alpha, MnSOD mRNA and protein expression were obviously higher than that of the normal group (P < 0.01, P < 0.05), with the significant decrease in the expression of 8-OHdG and the content of MDA (P < 0.01).
CONCLUSIONOxidative stress/lipid peroxidation enhancement in in NASH mice induced by high-fat diet may be related to the changes in SIRT1/PGC-1alpha signal transduction pathway. PTFC could enhance the anti-oxidant capacity in liver, relieve the damage of reactive oxygen during the fatty acid metabolic process, and prevent NASH from the occurrence and development by regulating the SIRT1/PGC-1alpha signal pathway.

To study the preventive effect of Grifola frondosa on nonalcoholic steatohepatitis (NASH). The rat model of NASH was established by feeding high-fat diets for 12 weeks and intervened with 0.5 g · kg(-1) · d(-1) and 1.0 g · kg(-1) · d(-1) of C. frondosa powder suspensions. The degrees of hepatocyte fatty degeneration and inflammation were observed under the optical microscope with routine HE staining. The NAFLD activity scores (NAS) were calculated. Serum ALT, AST and hepatic TG and CHOL were tested by the biochemical method. The hepatic MDA was examined by thiobarbituric acid method. The hepatic SOD was tested by the xanthine oxidase test. The hepatic GSH-PX activity was determined by the dithio-nitrobenzoic acid method. Hepatic TNF-α and IL-6 were detected by the enzyme-linked immunosorbent assay (ELISA). The NASH model group induced by high-fat diets showed higher hepatic NAS, ser- um ALT, AST, CHOL and hepatic TG, CHOL, MDA, TNF-α, IL-6 (P < 0.01 or P < 0.05) and lower serum TG and hepatic SOD, GSH-PX (P < 0.01, P < 0.05) than the normal control group. After being intervened with different doses of G. frondosa, the NASH group revealed significantly lower hepatic NAS, serum ALT and hepatic TG, CHOL, MDA, TNF-α and IL-6 (P < 0.05) and higher hepatic SOD, GSH-PX (P < 0.05) than the model group. G. frondosa may prevent the further development of NASH by improving the disorder of lipid metabolism in rats with NASH induced by high-fat diets, relieving the level of oxidative stress and reducing the generation of inflammatory cytokines.

OBJECTIVETo observe the influences of FVP1 on both curative and negative effects of CTX.
METHODThe present study included two parts of experiments. In the part 1, 0.2 mL of 1 x 10(7) mL(-1) of S180 cells were inoculated in the subcutaneous layer of the right armpit of mice. All the mice were randomly divided into 3 groups: control group, in which mice were given with normal saline in 10 consecutive days, CTX group, in which mice were injected with 30 mg of CTX in the first and third days and saline in the other 8 days during the 10 consecutive days of treatment, and FVP1 and CTX group, in which the mice were injected with 30 mg x kg(-1) of CTX in the first and third days and FVP1 at 10 mg x kg(-1) in all 10 consecutive days of treatment. After above 10-day treatment , all the mice were killed and the tumor body was taken out and weighed to calculate the inhibiting rates on tumor. In the part 2 of experiments all the mice were divided into 3 groups: Normal control group, in which mice were not treated with any drugs, CTX-induced model group of inhibiting immune system, in which mice were injected with CTX at dose of 10 mg x kg(-1) in first two days and saline in the following 7 days; and small-, meddle-and large-dosage of FVP1 groups, in which mice were injected with CTX at the same dose as above in first two days and FVP1 intraperitoneally at 5, 10 and 20 mg x kg(-1) respectively in the following 7 days. CTX group was regarded as the control model. After the treatment, the peripheral white cells, thymus index, spleen index, the phagocytic power of macrophage of abdominal cavity, lymphocyte trastation rate and the activity of NK cell were detected.
RESULT(DFVP1 plus small dose of CTX obviously enhanced the inhibiting rate of CTX on tumor in the mice inoculated with S180 cells. (2) FVP1 at the different dose obviously antagozized CTX-induced leucopenia, atrophy, reduction of the phagocytic power of macrophage in abdominal cavity and restored the function of lymphocyte translation and the activity of NK cells.
CONCLUSIONFPV1 could enhance the curative effect of CTX in depressing tumor and attenuate the negative effect of CTX in inhibiting the function of immune system.
