Objective To investigate the related factors effecting the genotoxicity and lipid peroxidation of organic ex-tracts from source water of Huaihe River and its tap water on mice.Methods XAD-II resin was used to absorb the organic chemical pollutants in source water and tap water.The mice were exposed to organic extracts through peritoneal injection continuously for5days.The micronucleus test,the sperm deformity test,the determination of the activities of SOD and GSH-Px and the concentrations of LPO in serum,liver and brain of mice were carried out.Results The fre-quncies of micronuclei and abnormal sperm of mice exposed to organic extracts at dosage of0.01ml/1g(bw)corre-sponding to100L/kg(bw)source water,finished water and tap water increased significantly compared with those of controls(P

Objective To ob se rve the effects of danazol on hypothalamus-pituitary-gonad axises and expressi ons of hypothalamic GnRH and pituitary GnRH receptor mRNA in female rats. Methods Female rats at 5 days of age were given a sin gle subcutaneous injection of 300 ?g danazol to induce true precocious puberty. Animals were divided into 3 groups: normal control, model group and vehicle gro up. The day of vaginal opening from 25 days of age was monitored, and the establ ishment of first estrus cycle from the day of vaginal opening was investigated b y examination of vaginal smears. The weights of body, pituitary, adrenal, uterus and ovary were measured to identify the developmental status of main organs. Th e expressions of hypothalamic GnRH and pituitary GnRH receptor mRNA were assayed by semi-quantitative RT-PCR. Results Female rats treated with danazol significantly (P

Objective To evaluate the cardiopulmonary allograft function and to analyze key factors for long-term survival of heart-lung transplantation in a patient survived more than 5 years. Methods On December 17th, 2003 at Zhongshan Hospital of Fudan University, a homologous heart-lung transplantation was performed on a female who diagnosed with cardiopulmonary failure secondary to congenital atrial septal defect with severe pulmonary hypertension. Heart-lung allograft was preserved with 1 000 mL UW solution and 4 000 mL HTK solution.Postoperative immunosuppressive therapies were managed with Zenapax, cyclosporine A (or tacrolimus), mycophenolate mofetil and corticosteroids. Cyclosporine A maintained with serum trough levels of 100-200 μg/L and tacrolimus with serum trough levels of 8-20 μg/L. Cardiopulmonary allograft functions were evaluated by echocardiogram, pulmonary function test and thoracic CT periodically. Results The patient survived operation and experienced normal daily life with NYHA cardiac function of class Ⅰ-Ⅱ during the follow-up of 5 years and 6 months. Echocardiogram showed left ventricular ejection fraction of 65% to 86%. Pulmonary function test exhibited with nearly normal oxygen exchange, meanwhile, small airway obstruction was detected from one year after operation and keeping stable from then on. Two episodes of severe pneumonia were complicated and treated with antibiotics and fhconazob, no severe acute allograft rejection episode was experienced. Conclusions Heart-lung transplantation proves to be a reliable therapy modality for terminal cardiopulmonary failure. Excellent donor organ preservation, accurate balance of the risk between acute allograft rejection and infection, and strict preventive measures against infection are key factors for long-term survival of heart-lung transplantation.

Objective To investigate the clinical effect of budesonide/formoterol single inhaler combined with tiotropium bromide in stable chronic obstructive pulmonary disease (COPD).Methods 80 cases of patients with stable COPD in China Aviation Industrial Xi'an Hospital from May 2014 to May 2016 were divided into observation group and control group,40 cases in each group.Patients in the control group were treated with budesonide/formoterol single inhaler,and in the observation group were treated with budesonide/formoterol single inhaler combined with tiotropium bromide.Compared the pulmonary function,life quality,serum levels of matrix metalloproteinases 9 (MMP-9) and interleukin 6 (IL-6),drug adverse reaction during the treatment and exacerbations episodes within the next six months.Results After treatment,the FEV1,FEV1/FVC,FEV1％ of two groups were significantly higher than before treatment (P ＜ 0.05),and in the observation group were significantly higher than that in control group (P ＜ 0.05).SGRQ scores,serum levels of MMP-9 and IL-6 of two groups were significantly lower than before treatment (P ＜ 0.05),and these indexes in the observation group were significantly lower than that in control group (P ＜ 0.05).The differences in the adverse reaction rate of two groups has no significant,the number of acute exacerbation in observation group were significantly lower than that of control group (P ＜ 0.05).Conclusion Budesonide/formoterol single inhaler combined with tiotropium bromide has remarkable clinical effect in stable COPD,and can effectively improve the pulmonary function,life quality,reduce the number of acute exacerbation,and reduce the serum levels of MMP-9,IL-6.

Objective To evaluate the chnical features and prognosis of traumatic benign paroxysmal positional vertigo (t-BPPV).Methods By retrospectively analyzing the results of clinical features and prognosis in 19 patients with t-BPPV from January 2003 to September 2006,the results were compared with 51 patients with idiopathic benign paroxysmal positional vertigo (i-BPPV).Results The mean ages were (51.3?19.1) years in t-BPPV group and (63.2?16.5) years in i-BPPV group,the difference was significant (t=2.57,P0.05).The one-stage success rates were 62.5% in t-BPPV group and 83.6% in i-BPPV group,the difference was significant (x~2=4.94,P

Objective To evaluate the efficacy and adverse effects of gefitinib in the treatment of fe- male patients with advanced adenocarcinoma of lung who had failed to previous chemotherapy.Methods These patients received 250mg of gefitinib orally,once daily until disease progression or development of intol- erable toxic reaction.They were evaluated one month after treatment and every other month thereafter.Results Among the 27 evaluable patients,there were 1 CR(3.7%),11 PR(40.8%),10 SD(37.0%)and 5 PD(18.5%). The overall response rate was 44.5%(95% CI 29%～68%);and 22 patients(81.5%)gained profit(CR+PR+ SD)from the clinical therapy(95% CI 62%～94%);the mean TTP was 7.2 months.Symptomatic improvement rate was 80.0%.The main adverse effects were mild rash and diarrhea.Conclusion gefitinib has significant efficacy in the treatment of female patients with advanced tung cancer who had failed to previous chemother- apy.Adverse effects are mild.gefitinib is a suitable therapy for these patients.
