Biliary atresia ( BA) is a pediatric liver disease characterized by progressive inflammation and fi-brosis of both the extrahepatic and intrahepatic bile ducts. Even though Kasai portoenterostomy increases the survival of children with BA, 80% of patients with BA will eventually require liver transplantation, making this condition the leading indication for pediatric liver transplantation worldwide. Currently,the causes of this disease are largely unde-fined and theories of pathogenesis include viral infection,autoimmune-mediated bile duct destruction,and abnormalities in bile duct development.

OBJECTIVETo compare the differences in the efficacy on depression after breast cancer operation treated with auricular point sticking therapy, the combined program of auricular point sticking therapy and TCM psychotherapy and medication with deanxit.

METHODSNinety patients were randomized into 3 groups, 30 cases in each one. In the western medication group, the simple oral administration of deanxit was applied, one tablet a day. In the auricular point group, Xin (GO15), Shen (CO10), Gan(CO12), Shenmen(TF4), Pizhixia (AT), Neifenmi (CO18) were selected and stimulated with auricular point sticking on either side in each treatment, once a week. In the combined program group, on the basis of the treatment as the auricular point group, TCM psychotherapy was combined with. The treatment of 4 weeks made one session. One session and 4 weeks follow-up were required. The self-rating depression scale (SDS) was used to compare the score before and after treatment in the patients of each group and the efficacy was assessed.

RESULTS(1) Compared with those before treatment, in 4 weeks of treatment and 4 weeks of follow-up, SDS scores were all reduced apparently in the 3 groups (all P<0.001). After 4 weeks of follow-up in the auricular point group, after 2 and 4 weeks of treatment and 4 weeks of follow-up in the combined program group, SDS scores were all lower than those in the western medication group (all P<0.05). (2) After 4 weeks of treatment, the curative rate in the combined program group was higher than that in the auricular point group and the western medication group [60.0% (18/30) vs. 40.0% (12/30), 36.7% (11/30), both P<0.05)]. After 4 weeks of follow-up, the curative rate in either the combined program group or the auricular point group was higher than that in the western medication group [60.0% (18/30), 30.0% (19/30) vs. 23.3% (7/30), both P<0.05].

CONCLUSIONThe auricular point sticking therapy, the combined program of auricular point sticking therapy and TCM psychotherapy, and medication with deanxit all relieve depression after breast cancer operation. The efficacy of the combined program with auricular point sticking therapy and TCM psychotherapy involved is the best, and the efficacy of the auricular point sticking therapy is better than the oral administration of deanxit.

Objective To investigate the correlation between the remnants of extrahepatic bilie duct with the prognosis of biliary atresia after Kasai operation.Methods From Sep.2005 to Sep.2011,93 cases of biliary atresia [51 boys and 42 girls,ages at operation:61 days(40-121 days)] in Tongji Hospital Affiliated of Tongji Medical College of Huazhong University of Science and Technology were operated with Kasai procedure,and the diagnosis of type Ⅲ biliary atresia was based on the cholangiography and the intraoperative findings.According to whether there was fibrotic remnant plates of porta hepatis or not,type Ⅲ biliary atresia cases were grouped into 2 subtypes:subtype A,in which there was fibrotic remnant plates of porta hepatis (n =80) ; subtype B,in which there was no fibrotic remnant plates,but solid cords structure like hepatic duct was observed(n =13).Specimens of the remnants were colleted in operation and pathologic section detected the degree of bile ductular proliferation in the remnants.Postoperatively,all of the patients were followed up.The contents included the cholangitis occurrence rate,the jaundice disappearance rate and survival rate during postoperative 2 years.Results The patients had more bile ductular proliferation in subtype A (x2 =18.49,P ＜0.05).There was no significant difference in incidence of cholangitis in postoperative 1 month between the 2 groups (x2 =0.01,P ＞ 0.05).The jaundice disappearance rate in postoperative 6 months of subtype A was higher than the rate of subtype B(x2 =9.19,P ＜ 0.05).The survival rate during postoperative 2 years of subtype A was higher than the rate of subtype B(x2 =4.49,P ＜ 0.05).Conclusions There are higher jaundice disappearance rate and 2 years survival rate in type Ⅲ biliary atresia with the fibrotic remnant plates of porta hepatis,which suggest that there is more bile ductular proliferation in the extrahepatic remnants which is good for biliary drainage in subtype A after Kasai operation,and it can slow down hepatic injury and have a long-term good life quality.

AIM:To observe the effects of Sini decoction against pulmonary injury induced by ex vivo ischemia-reperfusion in rats. METHODS: The model of ischemia-reperfusion was established. Twenty-four Sprague-Dawley rats were randomly divided into Sham, I/R, and SND groups. Wet to dry lung weight ratio (W/D), mean pulmonary artery pressure (MPAP), SOD activity and MDA contents in pulmonary perfusate and tissue, NOS activity and NO contents in pulmonary tissue were detected. The pathologic changes in pulmonary tissue were also observed by light microscope. RESULTS: The morphological changes of pulmonary injury were alleviated in SND group. Wet/dry ratio, MPAP and MDA contents in pulmonary perfusate and tissue were significantly lower in SND group after ischemic/reperfusion. SOD activity in pulmonary perfusate and tissue, and NO contents in pulmonary tissue were significantly higher in SND group than those in I/R group. No significant difference in NOS activity in pulmonary tissue among three groups was observed. CONCLUSION: These results indicate that SND may have a protective effect on ischemia-reperfusion injured lung by its antioxidant activity and by adjusting NO level.

Polyethylenimine (PEI) is a kind of nanometer nonviral vector frequently applied in gene transfection. It is simple and easy to prepare and to modify and relatively safe compared to viral vectors. In recent years, PEI has been utilized in many research areas for gene delivery to stem cells in vitro or targeted gene delivery to cells in the brain. This review reveals that the cytotoxicity and low transfection efficiency of PEI requires to be improved. However brain-targeted modification indicates the promising prospect of PEI for gene therapy in cerebrovascular diseases.

Conclusion The established mathematical models in this study could be applied for the stature estimation for Sichuan Han females.

This study was aimed to develop non-toxic, high transfection efficiency polyethyleneimine(PEI) cationic nanoparticles. The exosyndrome of PEI cationic nanoparticles was measured by zeta sizer, ultraviolet and visible spectroscopy. The condensation ability and the resistance to DNaseI of pEGFP-N1/PEI and pEGFP-N1/PEI modified polyethylene glycol(PEG) were evaluated by agarose gel electrophoresis. The cell toxicity of polyethyleneimine cationic nanoparticles was measured by using MTT test. The orthogonal design was used to optimize the transfection efficiency with the N/P ratio, the grafting ratio and the gene dosage as the factors. The experimental results showed that pEGFP-N1/PEI nanoparticles have lower cell toxicity, better composite ability and better resistance to DNAseI. The highest transfection efficiency of PEI cationic nanoparticles was 91% by using the PEI nanoparticles with the N/P ratio 40:1 and gene dosages 6 microg/well. PEI cationic nanoparticle modified by PEG effectively transferred DNA to hepatoma carcinoma cells and it is a non-toxic, with high transfection efficiency, and a promising non-viral carrier for gene delivery. The transfection efficiency will be improved by optimizing the experiment condition.
