Objective To improve the resection rate of central type hepatoma. Method Under selective exclusion of hepatic blood flow and the use of caritational ultrasonic surgical aspiration (CUSA), hepatectomy of central hepatic segments was performed for liver tumors. Result There were 46 cases in this group. Preoperative hepatic function was Child A in 43 cases and Child B in 3 cases. Regional entire bloodstream was excluded ranging from 8 to 33 minutes in 39 cases, Intraoperative blood loss was 100 to 2400 ml,the average was 490 ml. Postoperative hepatic function recovery to Child A grade in 43 cases within one week, postoperative aacites developed in 3 cases, jaundice in 1 case, biliary fistula in 1 case, gastroplegia in 1 case. One patient died of myocardial infarction 3 days postoperatively. Thirty-five malignant cases were followed-up with a mean period of 9 months, one died of intraabdominal metastasis 10 months postoperatively, the other 34 cases was alive without recurrence. Conclusion Hepatic regional entire bloodstream exclusion is effective in the control of intraoperative blood loss ; Hypersound-emulsifying- attractor separates blood vessels and bile ducts in hepatic hilar region. The combination of these two techniques helps in the resection of central hepatic tumors.

Objective To evaluate the use of ultrasonography befor and after inguinal hernioplasty.Methods In 30 patients, 32 inguinal hernias were submitted to tension-free inguinal hernioplasty,ultrasonography was applied before the surgery and after one mother. Ultrasonography revealed the character of the hernia before the surgery and observed the situation of the mesh after the surgery.Results Diagnostic ultrasound detected 20 inguinal hernias,4 direct hernias, and 3 femoral hernias which were consistent with intraoperative findings. We identified 2 seromas, 1 recurrence of hernia and 1 folding mesh after hernia repair. Conclusion Ultrasonography is a useful examination in preoperative assessing inguinal hernia and demonstrating postoperative complications associated with mesh.

At present,hepatectomy are recognized as the firsttreatment option for hepatocellular carcinoma (HCC).However,the patients have high frequency of recurrence after operation.In China,Most of the patients with HCC are related to chronic hepatitis B infection.The hepatitis B virus(HBV) factors such as:genotype,status of hepatitis B e antigen,HBV DNA level in serum and HBV DNA level in liver tissue influence the recurrence of tumors.Antiviral therapy,especially interferon therapy may be the effective method to prevent recurrence.HBV status also can influence the recurrence rate after transplant.

BACKGROUND: Some studies have demonstrated that the degradation of extracellular matrix (ECM), which matrix metalloproteinases (MMPs) participates in, plays a key step in the corneal neovascularization (CNV). Tissue factor pathway inhibitor 2 (TFPI-2), a new type serine proteinase inhibitor found recently, can effectively inhibit the activity of MMPs. Whether TFPI-2 gene transfection can influence CNV is unclear.OBJECTIVE: To investigate the effect of TFPI-2 gene transfection on CNV.DESIGN: Randomized controlled experiment.SETTING: Laboratory for Department of Surgery, Wuhan Union Hospital; Central Laboratory, the Affiliated Third Hospital of Sun Yat-sen University.MATERIALS: This study was carried out in the laboratory for Department of Surgery of Wuhan Union Hospital and State Central Laboratory of the Third Hospital Affiliated to Sun Yat-sen University between June 2004 and March 2006. Sixty healthy purebred adult New Zealand rabbits of either gender, weighing 2.5 to 3.0 kg, were involved. Preoperatively, no obvious anterior segment ocular lesion was found by slit-lamp examination. pBos-Cite-neo/TFPl-2 was kindly gifted by Dr. Zhong Ren (Department of Hematology, Union Hospital). Peroxydase blocking agent, nonimmune goat serum,mouse anti-human MMP-1, 2 and 3 monoclonal antibodies, biotin labeled goat-anti-mouse IgG second antibody (Santa cruz Company) were used in this study.METHODS: Experimental intervention: Experimental rabbit models of CNV were created in each group by silver nitrate cautery. Then, the rabbit models were randomized into 3 groups and 20 rabbits for each group. Different reagents were subconjunctivally injected via many points in each group: saline in the group Ⅰ, empty vector in the group Ⅱ, plasmid encoding TFPI-2 in the group Ⅲ. Experimental evaluation: CNV growth was observed under the slit-lamp biomicroscope.The expression of TFPI-2 in each rabbit model was detected by reverse transcription-polymerase chain reaction (RT-PCR) method 2 weeks after modeling; the expression of MMPs in corneal tissue was detected by immunohistochemical method at 3,5,7,9 and 14 days after modeling.TFPI-2 gene expression was significantly higher in the group Ⅲ than in the group Ⅱ and group Ⅰ (P ＜ 0.01); The MMP-1, 2, 3 expressions in the corneal tissue were significantly lower in the group Ⅲ than in the group Ⅱ and group Ⅰ,respectively, especially MMP-1, 3.

Tension-free repair for inguinal hernias has been led into China since 1997 and being promoted quick development of hernia and abdominal wall surgery in China,meanwhile,there are still many problems in the recurrence,chronic pain and patch infection due to irregular operations.In order to solve these problems and improve the diagnosis,treatment and research levels of hernia and abdominal wall surgery,surgeons must pay attention to the basic and clinical technologies,quality control and so on.The studies on etiology of hernia will bring innovative therapy,registration system will contribute to summarize the clinical experiences,and establishment and implementation of quality control of hernia could ensure the effects of diagnosis and treatment.However,there is still a controversy about whether laparoscopic technology on inguinal hernias is minimally invasive surgery or not,though it is safe and effective.

Corn meal was hydrolyzed in HCI ,and pH adjusted to 6.8 with (NH_4)OH. The substrate was inoculated with Cadida trapicalis ,then cultivated in a shaker at 30℃ and in 200r/min for 2 days. The Results indicated that the protein content in corn meal grew from 8.4 to 27.4%the lysine in the protein increased from 32.1 to 73.48/kg,the tryptophan from 6.8 to to 14.8g/kg. This shows that the nutritional value of corn meal can be improved with this method.
