OBJECTIVETo investigate the impact of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) on sperm DNA fragmentation and nucleoprotein transition.

METHODSBased on the recommended methods in the WHO Laboratory Manual for the Examination and Processing of Human Semen (5th ed), we conducted routine semen analysis for 65 CP/CPPS patients and 30 healthy men. We also analyzed the results of papanicolaou staining, sperm DNA fragmentation and sperm nucleoprotein transition.

RESULTSCompared with the healthy control males, the CP/CPPS patients showed significant decreases in sperm concentration ([134.05 +/- 99.80] vs [94.75 +/- 92.07]) x 10(6)/ml, P <0.05), the percentage of morphologically normal sperm ([7.26 +/- 2.28] vs [5.61 +/- 3.40]%, P <0.05) and sperm progressive motility ([59.18 +/- 16.06] vs [47.68 +/- 17.62]%, P<0.05), but dramatic increases in sperm DNA fragmentation ([22.92 +/- 11.51] vs [43.58 +/- 17.07%, P<0.01) and sperm nucleoprotein transition ([23.26 +/- 5.97] vs [32.14 +/- 8.79]%, P<0.01).

CONCLUSIONCP/CPPS significantly reduces sperm quality and male fertility.

To study the relationship between the interleukin (IL)6 -572G/C polymorphism and risk of hepatocellular carcinoma (HCC) in men.A hospital-based case-control study was conducted with 500 male HCC patients without tumor history in other organs and 590 healthy male controls without history of tumors or chronic diseases. All HCC cases were diagnosed by histopathology. The controls were recruited from the Department of Orthopedic Trauma and Ophthalmology at the same hospital. The IL-6 promoter -572G/C polymorphism and its genotype variants were detected by real-time fluorescence quantitative PCR. The Chi-squared test and unconditional logistic regression analyses were applied to determine the risk of HCC among men carrying the different genotype variants.The frequencies of alleles and distribution of genotypes in the -572G/C loci were not significantly different between the HCC cases and controls (P more than 0.05). The Chi-squared test indicated that the polymorphisms of the loci were not associated with HCC in our male population. However, after adjusting by multivariate logistic regression, the odds ratio (OR) of HCC for the G allele (CG + GG genotypes) carriers was 1.31 (95% confidence interval (CI): 1.00 - 1.71) compared with the CC genotype. Among the male HBV carriers, the CG genotype increased HCC risk significantly (OR = 1.60, 95% CI: 1.14 - 2.24) compared with the CC genotype. A trend test indicated that HCC risk was significantly increased with the numbers of G alleles (P trend less than 0.05). Breslow-Day tests of homogeneity of the ORs indicated an interaction between hepatitis B virus (HBV) infection and polymorphisms of IL-6 (P less than 0.05). The synthetic odds ratio (OReg) of HBV infection and harboring a G allele was 5.95 (95% CI: 3.99-8.87), which represented a super multiplication interaction.Polymorphism of the IL-6 promoter -572 loci may be associated with HCC occurrence in men. Moreover, there is a super multiplication interaction for HCC risk between HBV infection and harboring the IL-6 G allele.

Objective To determine the value and the optimal cutoff point of waist circumference (WC) in screening diabetes mellitus (DM) and to provide evidence for DM prevention and identifying population at risk in mid-western rural areas of Shandong province.Methods A sample consisting 16 341 rural residents was selected and studied.All participants were physically examined on height,weight,WC and fasting plasma glucose (FPG).Oral glucose tolerance test (OGTT) was performed for subjects with FPG valued from 6.1 to 7.0 mmol/L.DM was defined according to the criteria set by WHO in 1999.Area under the curve (AUC),sensitivity,specificity and Youden index were computed based on the receiver operating characteristic (ROC) curve analysis.Optimal cutoff point was determined by the maximum of Youden index.Results The prevalence rates of DM for males and females increased along with the rise of WC (trend test X2=72.01,122.65,P＜0.01 ).It appeared significantly higher in those with WC 85 cm in females and≥80 cm in males,with those WC ＜85 cm for females and ＜80 cm for males,in particular.AUCs were 0.639 and 0.655 for males and females respectively and both had significant differences (t=7.22,11.07,P ＜0.01 ).However,the AUCs did not show significant difference (t=0.70,P ＞ 0.05) between males and females.The Youden index reached maximum when WC approached 85 cm for females (24.90%) and 80 cm for males (24.39%).The sensitivity and specificity were 58.04%and 66.86%for males,and 67.08%and 57.31%for females.Conclusion WC seemed to be an effective indicator for screening the DM.The optimal cutoff point of WC would be 85 cm for females and 80 cm for males in screening DM and defining the population at risk in this area.

Objective To investigate the feasibility of 18G trocar for central venous catheterization in adults.Methods Retrospective analyzed the clinical data of 60 patients with central venous catheterization under local anesthesia.These patients were randomly divided into the control group and the observation group.Selected the internal jugular vein as the site of the puncture catheter.The control group was punc-tured by conventional puncture needle while the observation group was punctured by the 18G trocar.Results There was no statistical differ-ence between the two groups in the success rate of final puncture and catheterization(P>0.05).Compared with the control group,the suc-cess rate of guidewire insert was higher,the puncture operation time was shorter,the pain score during puncture operation was lower,and post-operative patient satisfaction was higher in the observation group.The differences of the two groups were statistically significant(P<0.05). Conclusion 18G trocar can perform central venous catheterization successfully.This method has great advantages for awake patients,and it also worked in some cases with difficult wire insertion.

OBJECTIVETo study the prevention, diagnosis and treatment of biliary complications after liver transplantation.

METHODSOne hundred and twenty-three recipients who had received liver transplantation between April 1993 and November 2001 were retrospectively reviewed.

RESULTSBiliary complication was diagnosed by cholangiography in 11 patients. Nine patients were cured, 1 patient was improved and 1 patient died. The incidence for biliary complications was 8.9% (11/123), and the mortality was 0.8% (1/123). The incidence of biliary complications due to T tube was 4.2% (5/119). The incidence of biliary complications due to hepatic artery was 1.6% (2/123). In recipients with WIT > 3 min and CIT > 8 h, the incidence of biliary complications elevated significantly.

CONCLUSIONSThe most important reason for biliary complications was preservative and ischemic injury. While repairing donor liver, damage to the blood supply system of donor liver bile ducts should be avoided. Meticulous T tube placement may reduce the incidence of biliary complications. Early cholangiography is helpful to diagnose biliary complications.

OBJECTIVETo investigate etiology, diagnosis, treatment and prophylaxis of liver abscess after orthotopic liver transplantation (OLT).

METHODSOf 274 recipients of OLT from January 1993 to June 2003 in our transplant center, liver abscess were identified in 6 recipients (2.2%). The clinical presentation included fever, shiver, abdominal pain, jaundice, hepatic dysfunction, hypoalbuminemia, anemia, leukocytosis and neutrophilia. They were diagnosed mainly according to the clinical presentation and Ultrasonography or CT scan. The treatments included aspiration and drainage of abscess, removing bile sludge, antibiotics and supportive therapy.

RESULTSOf 6 patients, 2 were cured, 3 refused liver retransplantation and 2 died of serious systemic infection. The cure rate was 33.3%.

CONCLUSIONSthe etiology of liver abscess after OLT is complicated. The predisposing factors might be included hepatic artery thrombosis or stenosis, MP pulse therapy, cholangitis and biliary interventional therapy. Its prognosis seemed disappointing. Strong prophylactic measures should be recommended to reduce the liver abscess after OLT.

OBJECTIVETo investigate the effect of adjuvant individualized chemotherapy in prevention of tumor recurrence and improvement of patient survival after liver transplantation for hepatocellular carcinoma (HCC).

METHODS21 HCC cases received orthotopic liver transplantation and treated with adjuvant individualized chemotherapy based on ATP tumor chemosensitivity assay (ex vivo) between April 2001 and January 2003 were retrospective reviewed, compared with 52 cases received orthotopic liver transplantation only. The cumulative and tumor-free survivals were compared between 2 groups.

RESULTSThe 1, 2 years overall survival rates were 92.31%, 73.85% for the individualized chemotherapy group and 92.06%, 63.93% for the non-chemotherapy group, the difference was not statistically significant. The 6, 12, 18, 24 months tumor-free survival rates were 90.00%, 80.00%, 80.00%, 60.00% and 67.31%, 51.92%, 40.03%, 37.81% respectively, the difference was statistically significant (P <0.05).

CONCLUSIONSThis study suggests that tumor recurrence decreases and tumor-free survival increases by adjuvant individualized chemotherapy after liver transplantation for HCC. The individualized protocol based on ATP-TCA may be effective for patients with HCC after liver transplantation.

OBJECTIVETo evaluate the role of orthotopic liver transplantation (OLT) in treatment of hepatocellular carcinoma (HCC) and the selection of recipients.

METHODSOLT was performed in 60 patients with HCC at Organ Transplantation Centre of the First Affiliated Hospital of Sun Yat-sen University between September 1993 and September 2002. Medical records were retrospectively analyzed with regard to the response to OLT and survival.

RESULTSOne-month, 1, 2, 3-year survival rate of 23 liver transplant performed from September 1993 to July 2002 were 73.9%, 60.9%, 43.5% and 29.0%, respectively. One-month, 1, 2-year survival rate of 37 liver transplant performed from August 2000 to September 2002 were 89.2%, 75.8% and 61.2%, respectively. One-month survival rate was significantly greater in the patients with a preoperative liver function of Child A or B than Child C (P < 0.05). One-month, 1, 2, 3-year survival rate of small HCC (single tumor 5 cm diameter, n = 41) were 84.2%, 76.6%, 65.6%, 65.6% and 82.9%, 63.1%, 46.7%, 37.4%, respectively. The median survival of large HCC was 18.0 months and mean survival of small HCC was 29.6 months, respectively. The recurrence rate of small HCC and large HCC were 15.8% and 27.7%, respectively. There was no significant difference between the cumulative survival of small HCC and large HCC. The quality of life of patients with long-term survival was good.

CONCLUSIONSHCC associated with cirrhosis can be effectively treated by OLT on condition that no extrahepatic spread and no vascular involvement. OLT is recommended for treatment of small HCC combined with liver cirrhosis, meanwhile, OLT performed in the partial large HCC still is reasonable at the present time.
