Objective To evaluate the clinical features of and appropriate surgical modality for congenital choledochal cyst(CCC). Methods Retrospective study on the clinical data of 85 surgically treated CCC cases was made. Results Among the 85 cases 12 were found malignant in character(14%). Out of the 29 cases in which the junction of pancreaticobiliary ductal system was showed by image, junction anomaly was identified in 26 cases. Surgical correction was applied to 83 cases with cyst excision and Roux-en-Y hepaticojejunostomy as the main procedure. External drainage of the CCC was adopted first in 4 cases to tide the patients over serious infection, before second stage definite radical resection was carried out. Excellent and good result were achieved on follow-up in 47 out of 60 CCC cases undergoing CCC resection and Roux-en-Y reconstruction, while only one out of 6 undergoing CCC internal drainage enjoyed fair result. Conclusions External drainage is mandatory for CCC patients with severe infection. The total choledochal cyst excision, with Roux-en-Y hepaticojejunstomy is effective in the treatment of CCC.

Objective To explore the relationship of dynamic changes between the iodine nutritional condition and growth of children born before and after the implementation of universal iodine.Methods By means of sampling investigation,urinary iodine and goiter,height,weight,intelligence quotient(IQ)were comprehensively evahated in children aged 7～14 years old born before and after the implementation of iodine in 10 counties and 2 cities of Qiannan.Results The median of urinary iodine of children Was 91.88μg/L in 1984,133.33μg/L in 1994,316.00μg/L in 2006;goiter rate was 21.40%(122/570)in 1984,12.86%(107/832)in 1994,5.28%(45/851)in 2006;the average IQ was 89.18±4.10 in 1994,94.26±0.94 in 2006;children in each age group in 2006 has a higher height and a heavier weight compared with those in 1984.Conclusion The physical development and intelligence of children in the areas of iodine deficiency have improved along with the correction of iodine deficiency.

This study aimed at investigating the inhibitory effects and the anti-tumor mechanisms of co-adminis-tration of fusion proteins mGM-CSF/βhCG ( GC ) and hVEGF121/βhCG ( VC ) on RM-1 prostatic cancer and B16 F10 melanoma in the C57 BL/6 J mouse model. Two recombinant stains containing pET-28 a-mGM-CSF-X10-βhCGCTP37 and pET-28 a-VEGF-M2-X10-βhCG-CTP37 were induced by lactose to express fusion proteins. The fusion proteins were separated and purified to prepare the anti-tumor protein vaccines ( VC protein vaccine and GC protein vaccine) , which were then mixed to prepare a combined protein vaccine named VGC protein vac-cine. The prostatic cancer and melanoma tumor-bearing mice C57 BL/6 J were immunized with described vac-cines, then the growth of each tumor was measured;splenocyte proliferation of immunized mice was detected;and the cytotoxic effects of the vaccine on tumor cells were tested. After that, the in vivo concentrations of IFN-γ and anti-hVEGF antibodies were investigated by ELISA. The difference between each experimental group and normal saline group ( NS) was statistically significant in both tumor-bearing mouse models ( P <0. 05) respectively. Besides, VGC group exhibited significantly better anti-tumor effect compared with the GC and VC groups with the anti-tumor rate ( 41. 7 ± 0. 83)% and ( 46. 4 ± 1. 27)% for prostatic cancer and melanoma tumor, respectively. The co-administration of the two proteins, VC and GC, could inhibit the growth of RM-1 prostatic tumor and B16F10 melanoma effectively via anti-tumor immunity and anti-tumor angiogenesis.

Effects of main environmental factors, such as temperature, pH , metal ions and anions, on expression and activity of bacterial extracellular car bonic anhydrase(CA) were studied, exemplified by a bacterium named GLRT102Ca, wh ich was separated from karst ecosystems of Southwest China. The results showed that the tested strain could express different activity of extracellular carboni c anhydrase within the scope of experimental temperature (10℃~50℃) and pH (5. 5~9.0). The activity of extracellular carbonic anhydrase was higher at tempera ture of 20℃~30℃ and at neutral and alkaline trending condition. Moreover, the expression of activity of extracellular carbonic anhydrase could be generally p romoted at the experimental range of concentration of 4 kinds of metal ions such as Ca2+, Mg2+, Zn2+ and Co2+, along with 8 kinds of ani ons such as SO2-_4, H_2PO-_4, NO-_3, NO-_2, Cl-,Br-, I- and HCO-_3. This research provides a cert ain theoretical basis for further study on the role of microbial CA in karst pro cesses.

Objective To investigate the incidence of auditory nerve pathway injury complicated with cere- bral palsy(CP) and its related factors relationship between the incidence rate of it and sexes,classification and risk factors. Methods The clinical data of 272 children with CP,including the data of brainstem auditory evoked po- tentials,were retrospectively reviewed.The incidence of auditory nerve pathway injury and the related factors were analyzed.Results In the 272 CP children,the incidence of auditory nerve pathway injury was 29.8% (81:272), which had a significantly relationship with the clinical types of CP (P0.05).In addition,it was found that the pathological jaundice (OR=2.945,95% CI:1.649-5.260) and intrauterine infection (OR=3.319,95% CI:1.037-10.625) were significantly related to auditory nerve pathway injury. Conclusion The auditory nerve pathway injury is common in CP children,especially in those with athetosis and mixed CP.Pathological jaundice and intrauterine infection are the risk factors of auditory nerve pathway injury.

Objective To investigate the effects of ischemic postconditioning (Post) on myocardial cell apoptosis and expres- sion of Bcl-2 and Bax protein during ischemia/reperfusion period in rabbits.Methods Eighteen rabbits were randomly allocated to three groups (6 in each group),sham operation (group S),ischemia/reperfusion group(group IR) and ischemic postconditioning group(group Post).Group IR and group Post were subjected to 15 minutes of left anterior descending coronary artery occlusion followed for 30 minutes of reperfusion.Ischemic postconditioning was achieved by three 30 seconds cycles of reperfusion,each followed by 30 seconds ischemia.Cardiomyocyte apoptosis were determined by in situ TDT-mediated dUTP nick end labeling (TUNEL) and DNA electrophoresis.The expression of Bcl-2 and Bax proteins in apoptotic myocardial cells were detected by immunohistochemistry sepa- rately.Results Compared with group IR,apoptotic index was significantly reduced in group Post [(28.06?2.92) % vs.(55.70? 13.96)%,P

OBJECTIVETo discuss the technique and its advantage on application of ultrasonic scalpel in laproscopic cyst excision with Roux-en-Y hepatoenterostomy.

METHODSForty-five cases were undergone laparoscopic cyst excision with Roux-en-Y hepatoenterostomy by ultrasonic scalpel. After intraoperative cholangiogram, the gallbladder and the dilated bile duct were completely excised by ultrasonic scalpel. Roux-en-Y hepatoenterostomy was performed extracorporeally through umbilical incision, then an end-to-side anastomosis was carried out intracorporeally.

RESULTSAll 45 cases were completely accomplished under laparoscope combined with ultrasonic scalpel. Median duration of operation was 4.2 h (3.5-6.0 h). Intraoperative bleeding was between 10-50 ml (median 15 ml). No complication were found during operation. All children were discharged in 3-9 d (median 5.5 d) after operation. Thirty-eight cases were followed up 1-18 months. No stenosis or ileus occurred. Liver functions were in normal level.

CONCLUSIONSTotal cyst excision with Roux-en-Y hepatoenterostomy by ultrasonic scalpel under the laparoscope was effective and safe for choledochal cyst. The most excellence was that clearly viewing during operation, less bleeding and injury, free of pain postoperation, microincision and scar.
