Objective To evaluate autonomic nerve preserving extended operation (ANPEO) for rectal cancer in the protection of postoperative urinary and male sexual functions.[WT5”HZ]Methods [WT5”BZ] 80 Dukes B and C cases underwent ANPEO for rectal cancer, including 10 cases with unilateral ANPEO. Result was compared with that of 25 cases undergoing traditional extended radical operation. [WT5”HZ] Result [WT5”BZ] Among 70 cases with bilateral ANPEO and 10 cases with unilateral ANPEO normal postoperative erectile was maintained in 97 1% vs 70%, ejaculatory functions in 92 9% vs 50%, ability of sexual intercourse in 91% vs 40%, and orgasm in 88 5% vs 40% respectively. In 25 cases without ANPEO extended operation sexual functions were all lost. 3/80 cases with ANPEO suffered temporary urinary dysfunction, 23/25 cases without ANPEO suffered temporary urinary dysfunction and 7 with long term dysfunction [WT5”HZ]Conclusions [WT5”BZ] ANPEO is effective to reduce the postoperative urinary and sexual dysfunction while maintaining the radical cure for the cancer.

Objective To investigate the methods and clinical significances of preserving the pectoral nerve(PN) and intercosto-brachial nerve(IBN) in modified radical mastectomy. Methods Eighty-seven patients suffering from breast cancer in stage Ⅰ and Ⅱ were randomly divided into 2 groups. Transpectoral anterior approach was used on patients in group A(n=52),with axillary lymph node dissection, preservation of the pectoralis minor muscles, PNS and IBNS. Patients in group B(n=35) were operated on through transpectoral posterior approach, with dissection of pectoralis minor muscles, sections of PNS and IBNS. Results No case in group A and 28 cases(80%) in group B suffered from postoperative atrophy of pectoralis major muscles(P

Objective To investigate the surgical approaches and effects for small hepatocellular carcinoma(HCC) with biliary tumor thrombi.Mothods The clinical data of 14 small HCC patients with biliary tumor thrombi who underwent surgical intervention were analyzed retrospectively.Results The postoperative mean survival time of patient with removal of biliary tumor thrombi(n=4) was 7 months.Three patients underwent limited hepatectomy and removal of biliary tumor thrombi,2 of them survived 4 and 21 months respectively,the other cases underwent second operation 2 months later for recurred tumor in liver.Eight patients underwent left or right hemihepatectomy and removal of biliary tumor thrombi,3 of them combined with extrahepatic bile duct resection and reconstruction.Survival times of these patients were 55 months,53 months,44 months(still alive),31 months(still alive),29 months,18 months,11 months(still alive) and 1 month respectively.Conclusions Regular hemihepatectomy,meanwhile combined with the invaded extrahepatic bile duct resection,might help to prolong the survival time of patients of small HCC with biliary tumor thrombi.

We developed a high-sensitivity C-reactive protein quantifiable chemiluminescent immunoassay (hs-CRP CLIA). The high-purity native CRP was purified from hepatic cirrhosis patient ascetic fluid by affinity and ion exchange chromatography and used as an immunogen to develop the monoclonal antibodies (mAbs) against CRP. Twenty-two mAbs were identified reactive with CRP in ELISA and 13 of them were reactive in the phosphorycholine ligand capture ELISA. The mAbs 10C5 and 10C11 were selected to develop the hs-CRP CLIA. The linearity and performance of the hs-CRP CLIA was characterized. It was showed not reactive when testing against other serum materials (IgG, hemoglobin and triglyceride). The reliable correlation (R2 > 0.993) was obtained between testing value (RLU/S) and the concentration of human serum CRP calibrator. The linearity fell in the range of 0.04-20.38 mg/L. The assay has good accuracy and reproducibility, the mean recovery was 99% and the precision of the intra- and inter assay was CVs (4.2%-5.8%) and (9.0%-11.5%), respectively. In testing of 90 human sera, this assay performed well and correlated comparably with a commercial hs-CRP ELISA kit. Thus, hs-CRP CLIA is an accurate, reliable, quantifiable assay for detection of high-sensitive C-reactive protein in serum, it may be useful to improve the risk assessment of cardiovascular disease and the prognosis of inflammatory bowel disease.
