Objective To investigate the effects of different analgesia protocols on immune function in patients undergoing surgery for ovarian neoplasms after neoadjuvant chemotherapy.Methods Forty ovarian neoplasms patients ageing from 31 to 62 years undergoing neoadjuvant chemotherapy were randomly divided into 2groups:epidural analgesia group (group E,n =20) and intravenous analgesia group (group Ⅰ,n =20).All patients underwent surgery under total intravenous general anesthesia.Patients in group E were given 2 mg morphine in epidural space at half an hour before abdomen was closed,then epidural analgesia pump was installed,with ropivacaine composite morphine in the pump.Analgesia time was 48 h.Patients in group Ⅰ were given sufentanil 0.1 μg/kg intravenously at half an hour before abdomen was closed,then analgesia pump was installed,with sufentanil compound flurbiprofen ester in the pump.Analgesia time was 48 h.The cervical venous blood samples were obtained from the patients at 30 min before surgery(T0),immediately(T1),12 h(T2),24 h(T3) and 48 h (T4) after the end of operation for determination of the expression of CD3 +,CD4 +,CD8 + on T cells and natural killer cell.Visual analogue scales (VAS)and adverse reaction at T2-4 were recorded.Results No statistical difference was found between group E and group Ⅰ in VAS and adverse reaction.Compared with T0,CD3 +,CD4 + T-lymphocytes,CD4 +/CD8 +,and NK cell decreased.Compared with group E,CD8 + increased at T1-2in both groups and at T3-4 in group Ⅰ.CD3 +,CD4+ T-lymphocytes,CD4+/CD8 + and NK cell decreased while CD8 + increased at T2-4 in group Ⅰ.Conclusion Epidural analgesia may be better to promote the immunologic function of ovarian neoplasms patients undergoing surgery after neoadjuvant chemotherapy.

Objective To evaluate the effect of 3-dimmentional conformal radiotherapy (3-DCRT) for mediastinal metastasis from esophageal carcinoma after surgery.Methods Sixty-three such patients were treated by 3-DCRT. Tumor diameter was: cm 20 patients. Positive supraclavicular lymph node was found in 9 patients. The number of tumor at the upper right, upper left and upper median mediastinum was 27, 27 and 20. All patients received 3-DCRT to the dose of 40?Gy (2?Gy/f, 5f/w), after resetting of portals, the dose was boost to 64～70?Gy by 3?Gy/f, 5f/w. Dose of the patients who had been irradiated was boosted to 50?Gy without further positioning. Results Complete response rate and partial response rate were 43% and 48% one month after the treatment was concluded,with no progression of disease. The 1-, 2- and 3-year survival rates were 75%, 43% and 15%. Conclusions Three-dimmentional conformal radiotherapy, with little side-effects, can markedly improve the local control rate and suvival rate of patients with mediastinal metastasis from esophageal carcinoma after surgery.

Objective To explore the value of echocardiography in the diagnosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in children.Methods The echocardiographic images of 14 patients with ALCAPA confirmed by operation and 18 patients with endocardial fibroelastosis (EFE) diagnosed by clinical were compared and analyzed.Results Both ALCAPA and EFE exhibited obvious dilated left ventricle,decreased left ventricular systolic function,thick endocardium and mitral regurgitation of different degree.The former additionally showed dilated right coronary artery(RCA) with normal origin,left coronary artery(LCA) emerging from the root or wall of the pulmonary artery(PA),the retrograde flow into PA in LCA and abundant collateral vessels in myocardium.However the later exhibited normal diameter of LCA and RCA and no collateral vessels.Conclusions Color Doppler echocardiography not only demonstrates left ventricular systolic function,endocardium,mitrial regurgitation and collateral vessels in myocardium,but also shows the origination and courses of LCA clearly,which provide exact informations to diagnose ALCAPA.The echocardiography can be used as a powerful tool of ALCAPA diagnosis and preoperative assessment.

Objective To explore the oxidative stress pathogenesis of Parkinson's disease(PD) induced by paraquat in substantia nigra of mice. Methods The model of PD was established by oral administration of paraquat to mice.The spectrophotometry was used to determine the activities of superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) and the content of malondialdehyde(MDA) in substantia nigra.At the same time,number of tyrosine hydroxylase(TH) positive neurons in substantia nigra of mice was estimated by immunohistochemistry. Results The activities of SOD and GSH-PX were significantly decreased,and the content of MDA was increased in paraquat-treated mice compared to that of mice treated by saline taken orally(P

Objective: Taking molecular sieve as a main component, to develop adsorbents which can selectively remove five kinds of heavy metal in Salvia miltiorrhiz extract solution. Methods: The 13X zeolite powder and active alumina powder were selected to compose adsorbent from four materials including iron red powder, fast powder (activated alumina), 13X molecular sieve powder, and zinc sulfide powder. The adsorbent formula was optimized with uniform design for mixture experiment. Pore-expanding agents, such as Chitisan and EDTA, were added to improve adsorbent pore structure. Results: With uniform design for mixture experiment, adsorbents with 13X zeolite ratio 0.275 6—0.465 5 could effectively remove five heavy metals (Cu, Pb, Cd, Hg, and As) in water solution. The optimal adsorbents from uniform design were hard to remove heavy metal in S. miltiorrhiz extract solution in 4 h, and removal ratios of Cu, Pb, Cd, Hg, and As were 14.4%, 74.5%, 54.6%, 13.4%, and 8.8%, respectively. With the same formula, pore- expanding adsorbents could effectively remove five heavy metals in S. miltiorrhiz extract solution in 4 h, and removal ratios of Cu, Pb, Cd, Hg, and As increased to 21.0%, 91.5%, 97.5%, 60.3%, and 46.8%, respectively. Conclusion: Pore-expanding adsorbents prepared in this study could remove five heavy metals in S. miltiorrhiz extract solution in short time, exhibiting industrial application prospect.
