Objective To study the reproductive outcome of infertile women suffered from hydrosalpinx treated by laparoscopic salpingostomy or salpingectomy.Methods There were 77 infertile women diagnosed hydrosalpinx by HSG or B ultrasonography and excepted for other infertile factors. Unilateral or bilateral salpingostomy or salpingectomy was performed after hydrosalpinx conifrmed by laparoscopy. Seventy seven patients were followed up for 1 ~ 4 years postoperatively.Results Among 77 cases 39 cases (50.65%) got pregnancy. Thirteen cases (16.88%) conceived spontaneously and 26 cases (33.77%) conceived by IVF-ETin. Thirty ifve cases delivered health babies and 3 cases of pregnancy, 1 cases of early abortion.Conclusion Both laparoscopic surgeries were effective treatment of hydrosalpinx results in infertility. After operation the pregnant rate of those conceived by IVF-ET is higher than spontaneously.

Objective To observe the therapeutic effect of electroacupuncture combined with rehabilitation exercises on swallowing function and cerebral perfusion in dysphagic stroke patients.Methods Sixty-two stroke pa- tients with dysphagia were randomly divided into a treatment group(n=32)and a control group(n=30).The treat- ment group received electroacupunture,rehabilitation exercise and conventional medical treatment,while the control group received only rehabilitation exercise and conventional medical treatment.They were treated once a day,6 times a week for 4 weeks.Water drinking test,stethocatharsis scores and swallowing fluorography were used to assess the swallowing function before and after treatment.Single photon emission computed tomography(SPECT)was also em- ployed to observe the status of cerebral perfusion before and after treatment.Results It was shown that the swallo- wing function and cerebral perfusion in the treatment group were significantly better than the control group after treat- ment.The effective rate in the treatment group was 96.88% while that of the control group was 66.67%.Conclu- sion Electroacupuncture combined with rehabilitation exercises is effective in treating the dysphagic stroke patients, and can significantly improve the brain perfusion of these patients.

Aim To observe the effects of cytokine signaling inhibition protein-3(SOCS3) on the liver fibrosis progression and reverse.Methods C57BL/6 mouse model was established by subcutaneous injection of carbon tetrachloride(CCl4).After a successful model of fibrosis, one-month normal diet was given to induce the reverse fibrosis model, while normal mice of the same gender and weight were as control group.Mice were sacrificed at 1, 2, 3, 4, 5, 6, 7, 8 weeks, respectively, then the liver tissue was harvested for the observation of its injury by hematoxylin and eosin(HE) staining.Then Masson staining was applied for the detection of changes in collagen, and the immunohistochemistry(IHC) for the observation of type Ⅰ Collagen(Colla-1), alpha smooth muscle actin(α-SMA), transforming growth factor beta 1(TGF-β1) and SOCS3 protein expression.In vitro formation of fibrosis was induced by TGF-β1 stimulating HSC-T6 cell lines, which was then reversed by MDI medium, with co-incubation of HSC-T6 cells with plasmid in the process of the reverse.Western blot was employed to detect SOCS3, Colla-1, α-SMA, TGF-β1 expression.Results The expression of SOCS3 and TGF-β1 increased in mouse model of fibrosis with the worsening fibrosis process and decreased in the reverse process.Over-expression SOCS3 in the reverse process reduced the development of liver fibrosis;meanwhile, the expression of TGF-β1 was also reduced accordingly.Conclusion SOCS3 may influence the development of the liver fibrosis and its reverse via regulating the expression of TGF-β1.

AIM To investigate the pharmacokinetic behaviors of total flavonoids from Epimedii Folium in osteoporotic rats in vivo.METHODS Twelve rats were divided into model group and sham group,after which the osteoporotic rat model was established by removing bilateral ovaries.After intragastric administration with total flavonoids (500 mg/kg),HPLC-DAD was applied to detecting the plasma concentrations of total flavonoids' prototype glycosides (epimedin A,epimedin B,epimedin C,icariin) and their metabolites (sagittatoside A,sagittatoside B,2-O-rhamnosylicariside Ⅱ,baohuoside Ⅰ,icaritin) at thirteen time points (0.083,0.25,0.5,0.75,1,2,3,4,6,8,12,24 and 48 h),then the plasma concentration-time curves were drawn,followed by the calculation of pharmacokinetic parameters.RESULTS Doubled peaks were observed in the plasma concentration-time curves of total flavonoids' prototype glycosides and their metabolites in both groups.Compared with the sham group,the integrated AUC and Cmax in the model group were significantly decreased (P ＜ 0.01),as well as the prolonged t1/2 (P ＜ 0.01).CONCLUSION The in vivo absorption and metabolism of total flavonoids from Epimedii Folium are much slower in the state of osteoporosis,thus affects the efficacy.

Objective To construct a prokaryotic expression system for human creatine kinase(CK) MM isozyme,purify the recombinant protein of CK expressed in Eschericheia coli(E.coli) and examine the stability of the recombinant protein for its application in CK measurement system as the quality control.Methods Total RNA of extracted from fetal cardiac muscle was reversetranscripted and cDNA encoding human CK was amplified which was inserted into pET-15b plasmid vector.The recombinant plasmid was transfered into E.coli BL21(DE3) and induced by isopropyl-?-D-thiogalactopyranoside(IPTG).Recombinant CK-MM was separated from bacterial proteins by affinity chromatography on a Ni2+-Sepharose column.The activity of the recombinant enzyme was observed in different matrixes.Results The enzymatic activity of the crude extracts of CK-MM was up to 280,000U/L.After one step affinity chromatography,the fusion protein showed a single band in SDS-PAGE gel.The purified protein was stable and the enzymatic activity remained unchanged for a month in the matrix containing bovine serum albumin,EDTA and 1,4-Dithiothreitol(DTT).Conclusion The recombinant CK-MM showed key properties of the native creatine kinase isozyme and may be used as control and calibrator for determination of serum CK-MM.
