Objective To evaluate the effect of hepatic resection for liver malignancies. Method The clinical data including the patterns and effect of operation in 108 patients with malignant liver disease underwent hepatic resection in recent 5 years in our hospital were analyzed retrospectively.Result Tweent-eight cases occurred complications and four died after operation . The 1-,3-year survival rate were 87.5% and 43.8% respectively. Conclusions Surgical resection is still an effective procedure for the liver malignancies .

AIM: To investigate DNA-binding activity of nuclear factor ka ppa B (NF-?B) and pyrrolidine dithiocarbamate (PDTC) anti-inflammation effect and mechanism in trinitrobenzene sulfonic acid (TNBS)-induced acute colitis in rats. METHODS: Acute colitis was induced by instilling TNBS/ ethanol into the lumen of the rat colon. Rats were randomized into PDTC-treat g roup (including group P10,P25,P50,P100), TNBS/ethanol group and normal control g roup. The rats in PDTC-treated group were injected intraperitoneally with PDTC at the dosages of 10, 25, 50, and 100 mg?kg -1 , respectively. Rats wer e killed at 4 h after enema. Colonic inflammation, the ratio of wet/dry weig ht and MPO, SOD, and MDA activity were detected. DNA-binding activity of NF-? B was assessed by EMSA. RESULTS: NF-?B activity in colon homog enate was increased markedly at acute colitis in rats. PDTC attenuates the devel opment of rat colonic inflammation but not by reducing the NF-?B activity. CONCLUSION: NF-?B is activated in rats with acute colitis, which may be a mechanism of self-protection. PDTC can attenuate the development of in flammation.

Objective To explore the experience of operative cooperation of trans-sternocostal triangle hand-assisted double lung metastatic tumor resection.Method The clinical data of 54 patients undergoing trans-sternocostal triangle hand-assisted double lung metastatic tumor resection were retrospectively analyzed from January 2005 to December 2005.Results The operations were all successful,with blood loss of 10~700 mL,operation time of 40~300 min,averaged(130.3+43.0)mins.One hundred and seventy eight malignant tumor lesions were removed.No serious complications occurred.Conclusion The key points to ensure thesuccessful operation were as follows:preoperation of special equipment,reasonable position,intraoperative strict aseptic operation,fixing of endoscopic incision suturing instrument,and accurate cooperation at all procedures.

OBJECTIVE: To establish a model of alcoholic liver fibrosis (ALF) in rats induced by complex factors. METHODS: Forty-seven healthy male rats were divided into three groups: normal control group (n=12), minor CCl4 group (n=12) and complex factors group (n=27). The rats in the complex factors group were fed a complex diet including alcohol, corn oil and pyrazole, and administered with intraperitoneal injection of minor CCl4 to induce ALF. During induction process, the histopathological changes of liver tissue and the values of liver-to-body weight ratio were both observed regularly. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (gamma-GT) in these three groups were all examined at the 12th week of the induction process. RESULTS: At the 12th week of the induction process, the model of ALF induced by complex factors was successfully established in rats, and the histopathological presentations showed alcoholic fatty liver, hepatitis and liver fibrosis in a sequence along with the induction process. The value of liver-to-body weight ratio and the serum levels of ALT, AST and gamma-GT of rats in the complex factors group were all significantly different from those in the other two groups. CONCLUSION: It is a steady and effective way to induce ALF in rats with complex diet and minor CCI4 injection.

Autoimmune encephalitis is a kind of inflammatory disease of central nervous system caused by abnormal immune response of body immune system to neuronal antigen,and is generally considered to be reversible encephalitis caused by noninfectious factors.Its characteristic manifestations include acute and subacute onset of cognitive dysfunction,epilepsy and mental disorder.With the discovery of related antibodies,summaries of clinical syndrome and application of new functional imaging instruments,the diagnosis of autoimmune encephalitis is increasingly standardized.The priority treatment of autoimmune encephalitis is immunomodulatory therapy,including glucocorticoid,immunoglobulin,plasma exchange and immunosuppressant.The other treatments could be the related tumor resection,electroshock therapy,etc.The symptoms in most patients can get substantial relief with active treatment.The present paper would focus on the research progress in treatment of autoimmune encephalitis.

Objective To investigate the diagnosis and treatment of pulmonary tuberculosis in renal transplantation recipients.Method The clinical data of 8 renal transplantation recipients suffering from pulmonary tuberculosis infection were retrospectively analyzed.Result Fever,cough and expectoration were the most common symptoms,however,lacking typicality.Images of chest Xray and CT scan were various and couldn't verify TB infection from pneumonia.Seven of 8 cases were diagnosed through invasive methods,either bronchofibroscope or fiberthoracoscopy.Immunosuppressants were decreased in all cases.Three-drug regimens,including isoniazide,rifampicin and ethambutol or pyrazinarnide,were administrated as anti-tuberculosis chemotherapy.All the cases were cured,without episodes like acute rejection and liver function impairment.Conclusion Routine examinations are not sufficient to diagnose pulmonary tuberculosis in kidney transplantation recipients.While,invasive methods like bronchofibroscope and fiberthoracoscope are helpful.When diagnosed,patients should receive normative anti-tuberculosis treatment and immunosuppressive agents adjustment,which can benefit the prognosis of pulmonary tuberculosis in renal transplantation recipients.

Background:The diagnosis of contrast-induced nephropathy (CIN) is usually based on changes in serum creatinine (sCr).However,sCr has poor sensitivity as a biomarker of kidney injury.The aim of this study was to investigate the usefulness of serum cystatin C (sCysC) to predict CIN after intra-arterial interventions.Methods:A total of 360 consecutive patients underwent intra-arterial procedures using digital subtraction angiography.SCr,sCysC,and estimated glomerular filtration rate were measured at 1 to 2 days before and at 48,72 h,and 7 days after the procedure.Results:Thirty-one patients (8.61％) developed C1N.Receiver operating characteristic (ROC) curve analysis showed that preoperative sCysC levels had good discriminatory power (area under the curve [AUC] =0.634;95 ％ confidence interval [CI] =0.526-0.743) for evaluating the risk of CIN after an endovascular procedure,with a sensitivity of 53.33％ and specificity of 73.70％.ROC analysis showed that sCysC at 48 h after contrast medium administration was predictive of CIN after an endovascular procedure (AUC =0.735;95％ CI =0.647-0.822) with satisfactory sensitivity of 74.20％ and specificity of 63.90％.Diabetes mellitus was an independent risk factor for CIN (odds ratio =2.778;95％ CI =1.045-7.382;P =0.040).Conclusions:SCysC is an appropriate biomarker to predict the occurrence of CIN.Baseline sCysC before an intervention is useful to obtain a preliminary estimate of the risk of CIN.A 48-h cut-off value of sCysC of 0.99 mg/L after an endovascular procedure may help to rule out patients at lower risk of CIN.
