OBJECTIVETo explore the molecular biological mechanism of ZHU's Tiaojing Cuyun Recipe (TCR) for treating anovulatory infertility patients with Shen deficiency syndrome (SDS) by observing its clinical efficacy.

METHODSUsing randomized blocking methods, 80 patients were assigned to the treatment group (40 cases) and the control group (40 cases). Patients with regular menstrual cycle started medication from the 5th day of menstruation. Those with irregular menstrual cycle first took progesterone till withdrawal bleeding ,and then started medication from the 5th day of vaginal bleeding. Patients in the treatment group took ZHU's TCR, one dose per day, while those in the control group took Clomifene Citrate (CC), 50 mg per day. Three menstrual cycles consisted of one therapeutic course, a total of 2 courses. Clinical efficacy such as pregnancy rates and abortion rates were observed. Ovulation indices (the maximal diameter of mature follicles, luteinized follicles, ovulational follicles, and the endometrial thickness on the ovulation day), SDS, and integrals of menstrual symptoms were monitored before and after treatment. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH) , and estradiol (E2) were determined using chemiluminescent immunoassay before treatment and after on therapeutic course. Serum levels of activin A (ACTA), inhibin B (INHB), and follistatin (FS) were detected using double antibody sandwich ELISA.

RESULTSCompared with the control group, the pregnancy rate was obviously elevated and the abortion rate was obviously lowered in the treatment group (P <0. 05). Ovulation rates of mature follicles and luteinizing follicles decreased more in the treatment group (P < 0.05). Compared with before treatment, integrals for SDS were lower, the maximal diameter of pre-ovulational follicles was increased, and integrals for menstrual symptoms in non-pregnant patients of the two groups were obviously lowered. Meanwhile, the endometrial thickness on the ovulation day was increased in the treatment group after treatment, but reduced in the control group (P < 0.05, P < 0.01). Compared with the control group, integrals for SDS were decreased, and the maximal diameter of pre-ovulational follicles was lowered in the treatment group after treatment (P < 0.05, P < 0.01). Integrals for SDS and the difference in the endometrial thickness on the ovulation day were increased, but the difference in the maximal diameter of pre-ovulational follicles were reduced (P < 0.05, P < 0.01). In the treatment group serum levels of E2 and ACTA increased more after one therapeutic course than before treatment (P < 0.01), but serum levels of INHB and FS decreased more after one therapeutic course than before treatment (P < 0.05). In the control group serum levels of FSH and ACTA increased more, and the serum level of FS decreased more after one therapeutic course than before treatment (P < 0.05, P < 0.01). Compared with the control group, serum levels of FSH and ACTA increased more, and serum levels of INHB decreased more in the treatment group after one therapeutic course than before treatment (P < 0.05, P < 0.01).

CONCLUSIONSZHU'sTCR could improve SDS of anovulatory infertility patients, regulate the follicular development, and elevate the pregnancy rate. Its actions might be associated with regulating their sex hormones, expressions of ovary local factors such as INHB, ACTA, and FS.

Background Retinal ischemia/reperfusion injury is a common pathological process in ophthalmology.It can cause permanent visual impairment.The prevention and treatment of retinal ischemia/reperfusion injury is one of the focus topics at home and abroad up to now.Objective Present study was to evaluate the protective effects of geranylgeranylacetone(GGA)on retinal ischemia/reperfusion injury.Methods The retinal ischemia/reperfusion models were established in 40 SD rats by the infusion of normal saline solution into the anterior ehamber to elevate the intraoeular pressure for 1 hour and then remove the process.GGA of 2 ml (800 ms/kg)was intragastrieally administered in 20 model rats as GGA group,and the equal volume of normal saline solution was used at the same way in other 20 models as model group.Four normal matched SD rats were served as normal control group.The histological changes of retina in 6,24,48,72 hours after modeling was examined by hematoxylin-eosin staining under the light microscope.and the expression of heat shock protein 70(HSP70)and caspase-3 in retina at the time points mentioned above was detected by immunohistochemistry.Results The edema of cornea and retina of rats appeared in 1 hour and peaked in 24 hours after modeling.In 72 hours after modeling,the edema was alleviated but the disorder of retina structure was found in model group.However,although the pathological change process was similar to that of model group,the damage of retina tissue was milder in the rats of GGA group under the light microscope.HSP70 and caspase-3 were absent in the retina of normal rats.But。The expression of HSP70 in retinal ganglion cells(RGCs)was found in 6 hours after modeling,reached peak in 24 hours and declined after that in model group.The numbers of positive cells for HSP70 in retina was significantly increased in various time points in GGA group,showing statistically significant differences between model group and GGA group(P<0.05).In model group,a few of caspase-3 positive cells were found 6 hours after reperfusion and increased gradually until reaching the peak 24 hours and then decreased gradually 48 hours later.Few caspase-3 positive cells were found 72 hour8 after reperfusion.The numbers of positive cells for caspase-3 decreased in GGA group compared with model group during the experimental duration with the considerable difference between these two groups(P<0.05).Conclusion GGA could protect RGCs against isehemia/reperfusion injury by upregulating the expression of HSP70 and downregulating the expression of caspase-3 in retina.

Objective: To investigate the mechanism responsible for lost sensibility of tyrosine aminotransferase (TAT) to dexamethasone(Dex) in human hepatoma cell line SMMC-7721 through examining the cDNA sequence of TAT and the status of glucocorticoid receptor (GR) pathway. Methods: The TAT cDNA fragment containing the full length of coding sequence was amplified by reverse transcription polymerase chain reaction (RT-PCR) and was sequenced. The expression of TAT mRNA was determined by real-time quantitative PCR to observe the influence of Dex on expression of TAT mRNA in SMMC-7721 cells. The experiement with HepG2 cells was performed as the control. Reporter genes (GRE-tk-LUC and GRE-MMTV-CAT) were transiently transfected into SMMC-7721 cells by electroporation. The induction effieiencies of LUC and CAT genes expression by Dex were examined and compared between SMMC-7721 cells and HepG2 cells. Results: The results showed that there was a same-sense mutation (Gln576Gln) in TAT cDNA sequence. TAT mRNA could be induced by Dex, with the maximal induction level being 2.22-folds in SMMC-7721 cells, which was significantly lower than that in HepG2 cells (15.1-fold increase, P<0.01). Dex induced the expression of LUC and CAT genes in SMMC-7721 cells as well as the HepG2 cells. Conclusion: The induction efficiency of Dex for expression of TAT mRNA is decreased in SMMC-7721 cells, which might be due to the unchanged activity of TAT.

Geographic information system (CIS) was applied to analyse the endemic situation of schistosomiasis and the distribution of snails in Dali City. Hie data of endemic situation of schistosomiasis in Dali City from 2002 to 2008 were collected and a CIS database was set up. The endemic situation and the distribution of snails and acute schistosomiasis cases were analyzed by ArcGIS 9. 2 software. The results showed that the schistosomiasis transmission areas included 11 towns, 91 villages, and 401 nature villages. The trend surface analysis suggested that snail distribution in 2008 had a trend to accumulate in the northwest, while the population infection had a trend of gathering to the southeast. All acute schistosomiasis cases distributed in 6 towns, 23 villages, which showed significant aggregation by space-time clustering analysis, and three endemic villages in Xizhou Town in 2002 were identified as the first stratum endemic areas. It is concluded that CIS as database and graphics management tools can describe the epidemic situation intuitively, imaginably and macrosopically.
