OBJECTIVE To evaluate the changes in serum levels of TNF-? and IL-6 after thoracic operation,and the relationship with multiple organ dysfunction syndrome(MODS).METHODS Serum levels of TNF-? and IL-6 in 46 cases of benign disease between 2000 to 2003 were observed on the day of operation,the 3rd,7th,14th and 21th days after operation,the patients were divided into two groups according to the presence of MODS.RESULTS Cases occurred MODS in two weeks after thoracic operation,the serum levels of TNF-? and IL-6 were markedly higher in MODS than that in non-MODS,the correlation coefficients between them were r=0.9145,P

Objective:To classify the types of radiographic feature of central salivary gland type malignant tumors of the jaws(CSMTJ) with studying the clinical data,radiographic characteristics and pathological classifications,and to help the diagnose CSMTJ correctly and effectively in future. Methods:The clinical,radiological and pathological features of 62 cases of CSMTJ were studied and summarized. Among these cases,52 cases were collected from the medical records of patients of the internal databank according to the World Health Organization (WHO) Histological Classification of Salivary Gland Tumors standard and 10 cases of CSMTJ were from Guangdong Provincial Stomatological Hospital. Results:The maxilla to mandible ratio was 1∶1.7,Among CSMTJ cases,central mucoepidermoid carcinoma of the jaws (CMCJ) was the most common pathological type and the second was central adenoid cystic carcinoma of the jaws(CACCJ). 62 cases of CSMTJ could be classified into four types:Unicystic type,Multicystic type,"Flame shape" type and Osteolytic type. Conclusion:The radiographic presentation of CSMTJ was very complicated and its classification was connected with tumor malignant degree. The classification was very helpful to determine the treatment methods and the prognosis of the CSMTJ.

Objective: To summarize the clinical application of reservation of partial duode- num in pancreaticoduodenectomy. Methods: 21 patients of pancreaticoduodenectomy were per- formed with partial duodenum, trans-ligment of Treits and upper-jejunum reservation from June 2000 to June 2005 in our hospital and the clinical data were retrospectively analyzed. Results: There was no death in operation; 2 cases with incision split due to infection after surgery were cured by secondary suture; the rest were discharged from hospital from hospital successfully; a mean period of in-hospital was 21 days, without bile leakage or pancreatic leakage. Follow-up period was from sixmonths to five years, and there were 18 cases with 1-year survival (85.7%), 14 cases with 2 - year survival(66.6%) and 3 cases with 3-year(14.2%). Condusion: Reservation of partial duodenum can reduce trauma caused by extensive anatomy and shorten operation time.

Primary immunodeficiency disease (PID) is a heterogeneous group of congenital disorders of the immune system.The impaired immune response is caused by defect of immune active cells and moleculars,which results in increased susceptibility to pathogens.Recurrent infection is the predominant presenting complaint for patients with PID.Early diagnosis,immunoglobulin replacement therapy,antimicrobial treatment,haematopoietic stem cell transplantation and gene therapy,genetic conselling and prenatal diagnosis will help to prevent and control infections in patients with PID.In addition,we should strengthen the education of paediatricians,improve awareness about PID and collaboration across different centers to advance the diagnosis and management of PID in China and save the life of patients at the maximum limit.

Thrombosis disease is a common complication of cancer. Researches show that venous thromboembelism ( VTE ) can increase the mortality rate of patients with cancer.Tissue factor (TF) and cancer procoagulant (CP) and other pathological factors are related to VTE.VTE risk factors in cancer patients can be grouped into 3 general categories:patient-related factors,cancer-related factors and treatment-related factors.Assessment of risk factors and early prevention can reduce the incidence of VTE.Immediate treatment and chronic therapy should be performed immediately after the diagnosis of VTE.

Objective To investigate the effects of the 2,3,4′,5-Tetrahydroxystilbene -2-O-beta-D-glucoside on the prolif-eration of PASMCs induced by hypoxia , in orde to search new drugs for the treatment and prevention of hypoxic pulmonary vascular remod -eling.Methods 3%O2 hypoxia was used to induced the proliferation of PASMCs .After hypoxic and TSG treatment for 24h, cell growth was determined by cell counting kit -8 ( CCK-8 ) , cell cycle was analysed by flow cytometry , the mRNA expression of HIF -1αwas measured by quantitative real -time PCR, and the reactive oxygen species ( ROS) production was determined by the fluorescence micro-plate reader .Results TSG can block the proliferation of PASMCs through G 0/G1 to S phase of the cell cycle arrest without cell cytotoxic-ity.Further experiments showed that TSG blocking the proliferation of PASMCs was associated suppression the mRNA expression of HIF -1αand the production of intracellular ROS in hypoxia -stimulated-PASMCs.Conclusion TSG can inhibit the proliferation of pulmo-nary artery smooth muscle cells induced by hypoxia through suppression the mRNA expression of HIF -1αand the production of intracel-lular ROS.

Objective To establish the quality standard of Huangqi-Changyu'an capsule. Method Thin layer chromatography was used to identify psoralen, evodia mtaecarpa, and nutmeg in Huangqi-changyu'an capsule. HPLC was used to determine the content of psoralen. A Hypeisil BDS C18 column(200 mm×4.6 mm,5 μm) was used with mobile phase consisted of acetonitrile-water (30:70) at the rate of 1 ml/min. The detection wavelength was set at 245nm with the column at room temperature. Results The liner range of psoralen was 3.572~53.58 μg/ml (r=0.999 9) with average recoveries of 99.04%, and the RSD was 0.8%. The liner range of isopsoralen was 3.796~56.94 μg/ml (r=0.999 9) with average recoveries of 99.20%, and the RSD was 0.6%. Conclusion This method is sentivive, accurate and rapid for the quality control of Huangqi-Changyu'an capsule.

Liver functional reserve which functioned as the major evaluation factor for the tolerance of the liver surgery or the liver trauma had already been used wildly in preoperative evaluation for liver surgery.So far there were plenty of techniques for liver functional reserve.But each technique had its own advantages and disadvantages.This article briefly discussed the most wildly used techniques for liver functional reserve in preoperative evaluation.

Objective To search for novel antifungal structures produced by marine fungus.Methods Using the Pyricularia oryzae (P.oryzaae) bioassay method to screen marine fungi led to the isolation of marine fungus 09-1-1-1.Active metabolites were isolated from the broth of the marine fungus 09-1-1-1.Results Two compounds were extracted from the mycelium and their structures were elucidated by various spectroscopic methods as 3a,12c-dihydro-8-hydroxy-6-methoxy-7H-furo\furo\xanthen-7-one(Ⅰ,sterigmatocystin) and 1,3,6,8-tetrahydroxy-2-(1-hydroxyhexyl)anthraquinone(Ⅱ,averantin).Conclusion The P.oryzae bioassay was a cheap,quick and convenient method for the screening of bioactive substances from marine fungi.Compound Ⅱ showed potent inhibitory activity to the mycelia of P.oryzae.The MIC of compound Ⅱagainst P.oryzae was 1.6 ?g?mL~(-1).
