In order to evaluate the pathogenisis, definite the position and mechanism of ovarian dysfunction. Methods Pi-tuitarygonadal hormones ,-.P and prolactin (PRL) were measured in 25 premenopausal hemodialysis women using enzyme im-munoassay (E3A). Results Patients' serum PRL levels significantly elevated, FSFKLH levels also elevated, whereas P levels were obviously lower compared with normal women. Conclusion (1) Hypothalamic-pituitary-ovarian axis was impaired in uremia women as indicated by the prevalence of acydicity and the failure of LH,E2 levels and marked low P levels. (2)In uremia women clomiphenum stimulation test was positive suggested that the pituitary-ovarian axis were normal, whereas hypothalamic was impaired. (3) Hyperprolactinemia, owing to increased pituitary prolactin secretion. Suppression with bromocriptine was unstable. (4) During dialysis, symptom treating is suitable rather than trigger the ovalation. Successful renal transplantation is the best treatment.

Objective To investigate the influence of pregnancy on graft after renal transplantation. Methods Clinic data from 13 female transplant recipients with pregnant duration more than 5 months from May 1978 to March 2002 were retrospectively analyzed. Results Immunosuppressive programs: 4 patients received CsA plus Pred, 5 CsA, MMF plus Pred, and 4 FK506, MMF plus Pred. Among the 13 cases, 10 had successful pregnancies with stable graft function; one died of pulmonary infection and cardiac insufficiency with functioning graft after delivery (the baby was safe); 2 experienced chronic rejection proven by biopsy, getting graft lost and pregnancy terminated: one returned to hemodialysis till now and one received successful retransplantation after 1 year hemodialysis. 11 offerings are healthy by now.Conclusion Patient/kidney survival in our study was 76.9?% . Our data and literature have demonstrated that pregnancy has no effect on graft long term survival or function. It is advisable in a woman of childbearing age with a well functioning renal graft 2 years after transplantation, but must be considered risk. Chronic rejection is a risk factor for graft loss following pregnancy. FK506,CsA and MMF have no side effect on newborns.

Objective To investigate the radiosensitization effect and underlying mechanism of Paeonol on human lung adenocarcinoma cell line A549 in vitro. Methods Cells were assigned to following groups:control,Paeonol alone,irradiation alone,Paeonol combined with irradiation.The effect of Paeonol on cell proliferation was evaluated by the MTT assay. Clonogenic assay was performed to measure the radiosensitization effect of Paeonol under three concentrations around 20% IC50.Cell apoptosis was determined by TUNEL assay and flow cytometry (FCM).The expression of Survivin protein was analyzed by Western blot.Results Cell growth was inhibited by Paeonol in a dose-dependent manner and the IC50 of Paeonol was (25.2 ± 2.1 ) mg/L. Clonogenic assay showed that Paeonol could markedly enhance cell radiosensitivity and the sensitizing enhancement ratio (SER) was 1.29.After the pretreatment of Paeonol with different concentrations,radiation-induced apoptosis increased with the doses at 24,48,and 72 h post-irradiation ( t =4.95,3.03,3.78,4.59,2.88,3.70,5.54,P < 0.05 ). Moreover,the protein expression of Survivin was obviously down-regulated by 22.6% - 56.7% ( t =4.15,7.30,13.47,P <0.05 ) due to the treatment of Paeonol.When the Paeonol-treated cells were further irradiated with 6 Gy X-rays,the expression of Survivin was reduced to 22.2% - 69.4% ( t =4.30,8.36,16.34,P < 0.05 ).Conclusions Paeonol had radiosensitization effect on the human lung adenocarcinoma cell line A549 in vitro,where the down-regulated Survivin protein might be involved.

Objective To investigate the effect of chronic low-dose manganese chloride exposure on cell cycle and apoptosis of spermatogenic cells in offspring rat. Methods 32 healthy female SD rats were randomly divided into control and manganese exposure groups(n=8).The manganese exposure group respectively received 2,4 and 8 mg/Kg MnCl2·4H2O,while the control group was treated with equal volume saline for 8 weeks(1 time/d,5 d/w).After mating with normal male SD rats and determining conception,female rats were continued to be ex-posed to manganese during pregnancy and lactation. There were. 8 offspring male rats in each group. In the 12th week,the offspring rates were randomly executed and their testes were used to observe the structure of seminifer-ous tubules by HE staining. The expression of FOXO3A,cell cycle associated proteins P16,P21,CDK2, CDK4,CDK6 and apoptosis related proteins BIM,Caspase-9 in the testis of offspring male rats were detected by western blotting. In addition,the apoptosis of spermatogenic cells was detected by TUNEL. Results(1)With the increase of administered-MnCl2 dosage,the seminiferous tubule showed various changes,including layers of spermatogenic cell decreased,spermatogenic cells arranged in disorder,the number of mature sperm in the lumen of seminiferous tubule significantly reduced.(2)The expression of FOXO3A,P16 and P21 increased while CDK2 and CDK4 decreased gradually with the increase manganese exposure dose. CDK6 expression was not significantly changed in all groups.(3)The expression of BIM,Caspase-9 and apoptotic index of spermatogen-ic cells increased gradually with the increase of manganese dose. Conclusion Chronic low-dose of manga-nese exposure could induce expression of FOXO3A,further cause cell cycle arrest and apoptosis of spermatogen-ic cells in offspring rat.

The present paper is aimed to observe the lateral attachment of the renal fascia (RF) in vivo with multidetector computed tomography (MDCT) scanning, and to discuss its diagnostic value. 121 healthy adults were adopted into this experiment. All images were obtained with MDCT and double phase enhancement scanning. Then we observed the lateral attachment of RF. In addition, we mad a fresh body specimen as anatomical basis. The study found that above the renal hilar plane (RHP), the anterior renal fascia laterally fused with the peritoneum of the liver on the right and the peritoneum of the spleen on the left,and the posterior renal fascia fused with the subdiaphragmatic fascia. The lateral attachment of the RF at the RHP and the lower renal pole(LRP)is divided into three types. The RF in Type I is about 47.9% (58/121) at the left RHP, while about 33.9% (41/121) at the right RHP. At the LRP of the kidney is about 55.3% (67/121) on the left, and about 42.1% (51/121) on the right. The RF in Type I is about 38.8% (47/121) on the left side at the RHP, about 26.4% (32/121) on the right side. At the LRP, left side about 27.3% (33/121), right side about 13.3%(16/121). The RF in Type III at the RHP is 13.3% (16/121) on the left side, and on the right side is about 39.7% (48/121). At the LRP, it is about 17.4% (21/121) on the left side, and about 44.6% (54/121) on the right side. MDCT can display the lateral attachment of the RF better as well as the outside connection of the retroperitoneal space.
