Biliary atresia (BA) is one of the most serious pediatric surgical digestive system diseases with progressive liv?er bile duct inflammation and fibrous obstruction. Currently, the etiology of BA is not clear. It may be associated with genetic predisposition, viral infections and immune injury. Now many scholars believe that it was resulted from multiple factors. Among them, the theory of immune-inflammatory is supported by most scholars. Now the mechanisms of CD38, CD138 and IgG4 in autoimmune liver disease were reported in literature. BA and other autoimmune liver diseases are similar in terms that both inflammatory and immune responses plays irreplaceable role during disease development. Therefore, this article briefly review the role of CD38, CD138 and IgG4 in the inflammation-immunity of BA.

Objective In order to evaluate the quality and performance of chlorine dioxide disinfectant,it is necessary to develop a set of methods to determine the components in chlorine dioxide disinfectant.Methods Iodometry,malonic acid iodometry,improved malonic acid iodometry and five-step iodometry were employed to determine the components including ClO_2, Cl_2,ClO_2~-,and ClO_3~-in chlorine dioxide disinfectant,the advantages and disadvantages of the test methods were compared.Results Using iodometry,the liquid stabilized chlorine dioxide products activated by hydrochloric acid,the content of ClO_2 was 20.23 mg/ml that was accord with the content which was marked in the product label.Using malonic acid iodometriy,the liquid stabilized chlorine dioxide contents of ClO_2 was 19.99 mg/ml,Cl_2 was 0.35 mg/ml,in which a little chlorine was detected.Using improved malonate iodometry and five-step iodometry,the activation rates of the liquid stabilized chlorine dioxide products were 88.0% and 75.6% respectively,ClO_2 and ClO_2~-in the liquid stabilized chlorine dioxide products could be distinguished.Conclusion Active chlorine dioxide and residual ClO_2~-can be detected by using iodometriy and improved malonic acid iodometry,but iodometriy and malonic acid iodometry can not.

Objective To investigate the expression and significance of integrin αvβ8, p38 and extracellular signal-regulated protein kinase 1/2 (ERK1/2) proteins, which are TGF-β1 pathway related regulatory protein, in liver fibrosis of children with biliary atresia (BA). Methods Fifteen cases of BA (Kasai group) and 10 cases of congenital biliary dilatation (CBD group) were collected in Tianjin Children’s Hospital. And liver biopsy specimens were collected in Tianjin first central hospital, including 10 cases of BA children who underwent liver transplantation due to liver failure after Kasai operation (liver transplantation group). The specimens of front part of the right lobe of the liver were taken for HE and immunohistochemistry (IHC) staining. The expressions ofαvβ8, p38 and ERK1/2 in liver were observed by IHC staining in three groups of liver tissues. Results HE staining showed fibroblast hyperplasia occasionally in CBD group, portal area expansion, fibrous tissue proliferation and wide spread bridging fibrosis with few pseudo lobules in Kasai group. In transplantation group, portal area was widened, the degree of fibrosis was severe and bridging fibrosis generally formed resulted in pseudo lobules widely. Imunohistochemistry showed that the expressions of αvβ8 and ERK1/2 were weakly positive, and the expression of p38 was negative in CBD group. In Kasai group, the expressions of αvβ8, p38 and ERK1/2 proteins were all strongly positive in liver cytoplasm, biliary epithelial cells and vascular endothelial cell cytoplasm. In liver transplantation group the expressions of αvβ8, p38 and ERK1/2 proteins were all strongly positive. The semi-quantitative analysis showed that the expressions levels of αvβ8, p38 and ERK1/2 were significantly higher in Kasai and liver transplantation groups than those of CBD group (P<0.05). There were no significant differences in expression levels ofαvβ8, p38 and ERK1/2 between Kasai group and transplantation group (P>0.05). Conclusion The expressions ofαvβ8, p38 and ERK1/2 are gradually increased in liver of BA with the process of fibrosis, which indicate that they may be involved in
the process of BA liver fibrosis.

Objective To evaluate the effect of the endotracheal tube (ETT) depth on the efficacy of bronchial blocker when used for one-lung ventilation.Methods Sixty patients of both sexes,aged 46-78 yr,weighing 48-85 kg,with body mass index＜30 kg/m2,scheduled for elective thoracotomy requiring one-lung ventilation,were divided into 2 groups (n =30 each) using a random number table:the distance between the tip of ETT and the carina was 3 cm group (group Ⅰ) and the ETT cuff was placed at 2 cm below the glottis group (group Ⅱ).The bronchial blocker was inserted under the guidance of a fiberoptic bronchoscope.The ETT depth,time to bronchial blocker position,development of bronchial blocker displacement and increase in airway peak pressure,degree of lung collapse,severity of postoperative tracheal mucous membrane injury and development of sore throat and hoarseness were recorded.Results Compared with group Ⅰ,the ETT depth was significantly shallower,the time to bronchial blocker position was shortened,postoperative tracheal mucous membrane injury was attenuated (P＜0.05 or 0.01),and no significant change was found in the incidence of bronchial blocker displacement and increase in airway peak pressure,degree of lung collapse or incidence of sore throat and hoarseness in group Ⅱ (P＞0.05).Conclusion The ETT depth the ETT cuff placed at 2 cm below the glottis can improve the efficacy of bronchial blocker when used for one-lung ventilation.

Measurement of cervical lordosis is the basic method for evaluating cervical function, and important reference for determine treatment decision. However, how to choose appropriate measurement in accordance with different situation, as well as the relationship among these methods is not clear. An increasing number of studies suggested that different measurements could directly affect the judgment of cervical lordosis. Therefore, comparative study of cervical vertebrae plays an important role in clinical treatment for cervical spondylosis under different cervical curvature conditions.
