Objective To explore the relationship between mutations in basic core promoter (BCP) of hepatitis B virus (HBV) and familial clustering of hepatocellular carcinoma (HCC) in Guangxi. Methods 153 pairs of members with HBsAg-positive were selected and matched from HCC high-incidence families and carcinoma-free families in Guangxi. The BCP genes were amplified and sequenced. Results The hotspot sites of the previous five mutations in BCP were T1762, A1764, G1775, V1753, G1803. In univariant analysis, HBV DNA≥105 copies/mL, T1762, A1764 and V1753 mutations were associated with the HCC high-incidence (P <0.05). The multivariate logistic analysis showed that HBV DNA≥105 copies/mL and A1764 were independent risk factors for it. Conclusion HBV DNA level, the mutations in BCP showed correlations with familial clustering of HCC in Guangxi.

Objective To investigate optimum dose of anesthesia in pediatric axillary brachial plexus branch block under ultrasound-guided. Methods Forty-eight children from May 2012 to May 2013 in hand surgery of our hospital,whose age was from 6 to 12 years,were randomly divided into four groups, each group has 12 cases. The doses of Ropivacaine were different in different groups. Group A was 0. 25 mL/kg,group B was 0. 2 mL/kg,group C was 0. 15 mL/kg,group D was 0. 10 mL/kg. And Ketamine was added to the treatment ac-cording to the incidence of anesthesia intraoperative. Evaluating the effect of anesthesia according to the situation of nerve block,observing an-esthesia duration time,dosage of anesthesia and rates of complications. Results The blocking effect of group A,B and C in each nerve area was correspond after 30 min,and anesthesia efficiency was higher than group D,but additional rate was lower than group D,the differences were statistically significant (P<0. 05). The block time in group D was shorter than the other groups,and the dose of Ketamine was most, and the block onset,perfect time were longer than the other groups (P<0. 05). But the differences between group A,B,C were not signifi-cant. Two cases in group D converted to general anesthesia. Four groups did not occur complication related narcotic drug. Conclusion In pediatric brachial plexus block used Ropivacaine under ultrasound-guided would get complete branch block,the exact effect of anesthesia, smaller dosage of local anesthesia. When the dosage of Ropivacaine was 0. 15 mL/kg could achieve a better anesthesia effect.

Objective To observe the expression change of HRG-1 gene between urinary bladder carcinoma and normal tissues,and to investigate the effect of HRG-1-siRNA on the proliferation and apoptosis of human bladder carcinoma cells.Methods Immunohistochemisty was used to detect the expression of HRG-1 in 85 cases of bladder carcinomas and 20 normal bladder tissues.The siRNA of HRG-1 was designed,synthesized,and transfected into bladder cancer cell line T24.Results The HRG-1 gene expression had significant differences between bladder carcinoma and normal bladder tissues (P ＜ 0.05).The positive expression of HRG-1 gene had significant differences between the pathological grades and clinical stages of bladder carcinomas (P ＜0.05).After treated with siRNA,the expression levels of HRG-1 protein and mRNA in T24 cells decreased obviously (P ＜ 0.05).The apoptosis rate of T24 cells transfected with HRG-1-siRNA was significantly different from control-siRNA group and blank group (P ＜ 0.01).Conclusions The high expression of HRG-1 gene may play an important role in bladder carcinoma,and siRNA targeting HRG-1 can suppress HRG-1 protein expression markedly and enhance apoptosis of T24 cells.

Objective To explore the expression of a new candidate tumor suppressor N-myc downstream regulated gene 2 (NDRG2) in bladder cancer tissues and to investigate its clinical and pathological significance.Methods Formalin-fixed,paraffin-embedded tissue sections from 62 cases of bladder carcinomas and 10 cases of normal bladder tissues were analyzed retrospectively with immunohistochemistry (S-P method).Results The NDRG2 gene was highly expressed in normal bladder tissues,but low expressed in bladder carcinoma tissues.Positive expression of NDRG2 was detected in 8 of the 10 (80.0％) normal tissues and 40.3％ in bladder carcinoma ones (x2 =3.98,P ＜0.05).Furthermore,with the degree of malignancy increased,the positive expression of NDRG2 in bladder carcinoma samples was decreased.The expression of NDRG2 in bladder carcinoma was negatively correlated(r =-0.288,P ＜0.05) with C-myc(r =-0.436,P ＜0.01) and positively correlated with p53 in bladder carcinoma tissues(r =0.717,P ＜0.01).Conclusions The level of NDRG2 expression was lower in bladder carcinomas than in normal tissues.NDRG2 may play an important role in bladder carcinogenesis and in the progress of bladder cancers.

Objective To explore the change of venous blood phase values detected by enhanced gradient echo T2 star weighted angiography(ESWAN)sequence in mild and severe traumatic brain injury (TBI) models of rabbits in diverse phases and investigate their association with neurological severity scale (NSS) scores. Methods Fifty-one New Zealand rabbits, which were randomly divided into control group (n=3) ,mild injured group (n=24) , and severe injured group (n=24) by random digital table method, underwent routine MRI and ESWAN sequence at the time points of baseline, 1 h, 6 h, 12 h, 24 h, 48 h, 72 h, 1 week, and 2 weeks after injury(3 rabbits per subgroup)respectively. Blood phase values in veins of interest were recorded. Observation of behavior characteristics and abnormalities, followed by NSS, was executed post injury, and the correlation between venous blood phase values and NSS scores was statistically analyzed. Two independent-samples t-test was applied to compare venous blood phase values of diverse measured veins in each group separately at every time ponits. One-way ANOVA was used to analyze venous blood phase values varying over time of measured vessels in each injured group. Least significant difference t-test was applied to compare blood phase values within the subgroups with each other at each time point. NSS scores of mild and severe injured groups were compared by two independent-samples t-test. Correlations between venous blood phase values and NSS scores in each vein and group was analyzed with Spearman correlation analysis. Results Blood phase values in veins of interest presented an inclination of descending, which was more obvious in severe injured groups than in the mild. Change of venous blood phase values over time featured continuing reduction in earlier phases which reached to the minimum in 24-48h, and then increased gradually, especially in VMV, VLV, DSS, and MDVB (P<0.05). ICV and DCV also showed similar trend. Values of NSS scores in the two group were (15.5 ± 3.1) and (33.2 ± 6.5) respectively (t=3.543,P=0.001). Blood phase values in most of the measured veins correlated with NSS scores (P<0.05) after 6h post injury, especially significant during 24-72h among all the measured veins(P<0.05). Higher accuracy and sensitivity were presented in the supratentorial or superficial veins compared with subtentorial or profound veins. Conclusions It is feasible to evaluate oxygen saturation of veins after TBI by measuring venous blood phase values on ESWAN images. The method is effective in the assessment of the degree of injury and clinical status, indicating a favorable application prospect.
