Objective To investigate the effectiveness and technical points of anatomical liver resection by trans-Glisson Sheath methylene blue staining in treatment of hepatolithiasis of right posterior lobe.Methods The clinical data of 12 cases of hepatolithiasis of right posterior lobe treated with anatomical liver resection by Glisson sheath methylene blue staining were retrospectively analyzed.Result 6 of 12 patients had undergone more than 2 previous biliary surgeries.All patients underwent contrast-enhanced CT scan and portography,hepatolithiasis of segment Ⅵ in 4 cases,right posterior lobe in 8 cases,accompanied by left lateral lobe bile duct stones in 2 cases,the right caudate lobe bile duct stones in 1 case.Methylene blue was injected into the portal vein,the methylene blue interface of segment Ⅵ or right posterior lobe displays well.Methylene blue interface was larger than the ischemia interface,which is in accordance with the anatomy.Along the methylene blue interface,hepatic resection was performed including right posterior lobe resection (n =9),segment Ⅵ resection (n =3),and combined with left lateral lobe resection (n =2) and the right caudate lobe resection (n =1).There was no postoperative mortality.Incision infection occurred in 5 cases,4 had right pleural effusion and 2 had a biliary fistula that were treated conservatively.With a mean follow-up period of 3.2 years,all patients are symptoms free and stone free.Conclusions Anatomical liver resection by methylene blue staining is a safe and effective treatment for hepatolithiasis of right posterior lobe.

Objective To investigate the mutations of basal core promoter (BCP) and precore (PreC) region of hepatitis B virus (HBV) and the association with the development of hepatocellular carcinoma in patients with chronic HBV infection.Methods Totally 381 untreated HBV patients were recruited from the Department of Infectious Diseases,People's Hospital of Shangyu from Jan 2003 to Dec 2010,which included patients with chronic hepatitis B (CHB,n =166),cirrhotic hepatocellular carcinoma (cirrhotic-HCC,n =158) and noncirrhotic hepatocellular carcinoma (noncirrhotic-HCC,n=57).The mutations in HBV BCP and PreC and the genotypes of HBV were determined by polymerase chain reaction (PCR) and direct sequencing.Data were analyzed by chi square test and Logistic regression.Results The HBV genotype of most cases was genotype B (CHB,n =124;cirrhotic-HCC,n=126 ; noncirrhotic-HCC,n=50).In univariant analysis,BCP V1753 (x2 =7.927,P=0.005),BCP T1762/A1764 (x2 =12.796,P＜0.01),PreC A1896 (x2 =6.890,P=0.009) and PreC A1899 (x2=11.850,P =0.001) mutations were more frequently detected in cirrhotic-HCC patients than those in CHB patients.PreC A1896 (x2 =27.310,P＜0.01) and A1899 (x2=7.575,P=0.006) mutations were highly detected in noncirrhotic-HCC patients than those in CHB patients.Multivariate Logistic regression analysis revealed that in HBeAg positive patients,BCP T1762/A1764 (wald=6.180,P=0.016,OR=8.883) and PreC A1899 (wald=10.279,P=0.001,OR=7.475) mutations were independently associated with the development of cirrhotic-HCC; PreC A1896 (wald=4.324,P=0.038,OR=4.439) and PreC A1899 (wald=4.850,P=0.028,OR=6.010)mutations were independently associated with the development of noncirrhotic-HCC.While in HBeAg negative patients,PreC A1896 mutation (wald=15.448,P＜0.01,OR=12.128) was independently associated with the development of noncirrhotic-HCC.Conclusions BCP T1762/A1764 mutations are associated with the development of cirrhotic-HCC in HBeAg positive patients.PreC A1896 mutation is associated with the development of noncirrhotic-HCC in HBeAg positive and HBeAg negative patients.PreC A1899 mutation is associated with the development of cirrhotic-HCC and noncirrhotic-HCC in HBeAg positive patients.

Objective To investigate the correlation of anthropometric indicators and blood pressure in children. Methods A total of 6 790 children aged 6 to 13 years were inspected by random sampling. The body mass index (BMI), waist circumference (WC), hip circumference (HC), and blood pressure were measured. The waist/hip ratio (WHR) and waist/height ratio (WHtR) were calculated. The data wrer analyzed by SPSS16.0 statistical software. Results The detection rate of hypertension in children was 5.57%. After controlling for age, both in male and female children, the BMI, WC, HC, WHR, WHtR and systolic blood pressure showed a significant positive correlation by partial correlation analysis (all P<0.05). Both in male and female children, the BMI, WC, HC, WHR, and WHtR were significantly higher in children with hypertension than those in children with normal blood pressure (all P<0.05). Among all subjects, 280 children (4.12%) were obese, 622 children (9.16%) were overweight. The detection rates of hy-pertension were significantly different among obese, overweight and normal weight children (P<0.01). The detection rate of hypertension was significantly higher in obese children than that in overweight and normal weight children. The systolic and diastolic blood pressure were all significantly higher in obese and overweight children than that in normal weight children (P<0.05). Conclusion The hypertension prevalence of children aged 6 to 13 years in Zhengzhou is in the low to median level in the same age groups. The BMI, WC, HC, WHR, WHtR are signiifcantly correlated with blood pressure in both gender, and the correlation is the most obvious in HC.

Objective Boy sexual development is affected not only by age, but also by environment factors .The present study was to survey and evaluate the status of sexual development in boys from Zhengzhou area and to explore their influencing factors. Methods The height, weight, waist circumference, hip circumference, penis and testicles in 3779 boys aged from 6 to 13 years old in Zhengzhou were measured .The penis length and testicular volume of different ages and their influencing factors were compared, and the beginning age and sexual development characteristics were explored .The development of genitalia and pubes were evaluated by Tanner staging criteria and standards, which were divided into five stages. Results There were 3779 boys, including 395 overweight cases (10.45%) and 208 obesity cases (5.50%).The testicular volume and penis length increased by age, which increased slowly at the age of 6 to 11, followed by a rapid increase after the age of 11 year old.Testicular volume increased more rapidly than that of penis length. The medians quartile of testicular volume in overweight group ,obese group and normal group were 2.50 mL, 2.50 mL, 2.00 mL, 2.00 mL,2.00 mL,1.00 mL respectively .The testicular volume in overweight group and obese group were significantly greater than that in nor -mal group (P<0.01) and there were no difference between overweight group and obese group .The penis length in overweight group and obese group were significantly less than that in normal group (P<0.01), and there was no difference between overweight group and obese group.Testicular volume and penis length were positively correlated with age, height, weight, body mass index, waist circumference and hip circumference; the correlation between testicular volume and height, penis length and age were the strongest. The age of development of testicle (average 12.02 years) in urban area was later by 2.73 years than that in the rural area (average 9.9 years), the difference was statistically significant (P<0.001).The age of pubic development (P2) and maturity (P5) was (12.34 ±0.83) years and (12.39 ±1.24 ) years.The incidence of precocity in boys was 0.40%. Conclusion The sexual development of boys from Zheng-zhou area is similar to the results of large scale survey from China .Attention should be paid to the effect of obesity on sexual develop-ment, and early intervention should be given, the occurrence of adverse events of sexual development can be avoided .

BACKGROUND:Peri-fracture nerve injury can inhibit osteoclast activity and promote early fracture healing. OBJECTIVE:To investigate dynamical y the effects of traumatic brain injury on the bone mineral density, microstructure, biomechanics property and bone metabolism in rat models of fractures. METHODS:Sixty-three male rats were randomly divided into three groups:sham group, simple fracture group and fracture combined with brain injury group. After 3, 6, and 3 months, the animals were sacrificed in batches under anesthesia, and then, the bones and serum specimens were used to detect the bone mineral density, microstructure, biomechanics property, serum cross-linked N-telopeptide of col agen type I and osteocalcin levels. RESULTS AND CONCLUSION:Compared with the simple fracture group, the fracture combined brain injury group had significantly increased bone mineral density of the proximal tibia, bone volume fraction of the cancel ous bone, trabecular thickness, cross-sectional area of tibial cortical bone and total area of the bone marrow, ultimate load and stress of the tibia, serum cross-linked N-telopeptide of col agen type I and osteocalcin levels at 3 and 6 weeks after modeling (P<0.05), but no differences in the above-mentioned indexes were found among the three groups at 3 months after modeling. These findings indicate that traumatic brain injury can increase the bone mineral density at the fracture site, improve bone microstructure and enhance biomechanical properties, thereby promoting bone healing and bone metabolism at the fracture site.
