Purpose:To investigate the prevention and treatment protocol for Af after resection of esophageal and car- dia carcinoma.Methods:Analyses for clinical materials of 1527 patients underwent resection for esophageal and cardiac carcinoma.Results:There were Af 23 cases.Age older than 60 years,abnormal ECG or/and pulmonary function before operation,gastro-esophageal anastomosis above the aortic arch and histological staging Ⅲ～Ⅳ were risk factors for AF.Fa- tal AF was rarely seen.In our 23 cases after treatment in time AF disappeared.Conclusions:Further recognition for post- operative AF and management of perioperative period complication,may reduce the danger of postoperative AF.

Neurotransmitter release is controlled by groups of proteins associated with the membranes of synaptic vesicles and the presynaptic membranes.It is a highly dynamic process which is spatially and temporally regulated via a cascade of protein-protein interactions.These proteins participate in each step of the synaptic vesicle circulation at nerve terminals including the formation of soluble N-ethylmaleimide-sensitive factor-attachment protein receptors complex,the targeted trafficking of synaptic vesicles,the vesicle docking,the neurotransmitter release and finally the reuse of the proteins.This article focuses on the physiological function and the interactions of these regulating proteins.

Objective To analyze the epidemiologic features of visceral leishmaniasis in different age groups in China from 2005 to 2012,and to provide a scientific basis for prevention and treatment of the disease.Methods The visceral leishmaniasis cases were obtained from China disease epidemic monitoring information system from 2005 to 2012.All the cases were divided into subgroups by demographic characteristics:infant (＜1 year old),childcare (≥1 and ＜4 years old),child (≥4 and ＜15 years old),adult (≥15 and ＜65 years old) and senior adult (above 65 years old).The epidemiologic features,such as gender,season of disease onset and area distribution of visceral leishmaniasis were analyzed.Results The total reported visceral leishmaniasis from 2005 to 2012 were 2 979,among which cases in infant,childcare,child,adult and senior adult were 24.9％,21.7％,20.0％,32.4％ and 1.0％,respectively.Infant cases were most reported in April; childcare cases in December which began to increase since September; child cases in October and adult and senior adult in March.The reported cases were mainly from Xinjiang,Gansu and Sichuan areas.However,age characteristics differed among regions,which were mainly infants,both childcare and children,and adults,respectively in this three areas.The duration from onset to diagnosis was shortest in infant group (11 d) and longer in adult group (15 d).Conclusions The number of visceral leishmaniasis cases in different age groups peaks in different months.Regional distribution is not even.Cases are most concentrated in Xinjiang,Gansu and Sichuan areas.Infants predominate in Xinjiang,childcare and children in Gansu and adults in Sichuan.

OBJECTIVETo study the influence of different drying methods on the quality of Schisandrae Chinensis Fructus and thus provide useful reference for its proper drying methods.

METHODSchisandrae Chinensis Fructus was processed by eight drying methods including vacuum freeze drying, natural drying in the shade, drying in the sun, oven drying and vacuum drying under different temperature. The contents of the functional ingredients includes chisandrin, gomisin D, gomisin J, schisandrol B, angeloylgomisin H, angeloylgomisin Q, gomisin G, schisantherin A, deoxyschisandrin, schisandrin B, schisandrin C, 5-HMF, total aids and total sugars. The main components change after drying were analyzed by HPLC, ultraviolet spectrophotometry and potentiometric titration. Principal component analysis (PCA) was carried out by SPSS software to evaluate the quality of different processed products from Schisandrae Chinensis Fructus.

RESULTAll these results are in accordance with the requirements of Chinese Pharmacopoeia published in 2010, the contents of schisandrin and total eleven lignans were the highest using vacuum drying, and 5-HMF were the lower, oven drying made little difference but with lower schisandrin and higher 5-HMF as the heat increased.

CONCLUSIONDifferent drying methods have significant influence on the quality of Schisandrae Chinensis Fructus. Oven drying under 5°C should be adopted to substitute drying in the sun according to the China Pharmacopoeia published in 2010 for Schisandrae Chinensis Fructus by comprehensive analysis of the cost, content and practicality.

Proteinase inhibitors are widely distributed in many living organisms and play crucial roles in many biological processes, particularly in regulating the proteinase activity spatially and temporally. However, The Kazal family of serine protease inhibitors is one of the most important and extensively studied protease inhibitor families. This type of protease inhibitor normally consists of one or several domains. Every domain has a highly conserved sequence structure and molecular conformation. It is found that contact residues are hyper variable, which are responsible for the interaction of inhibitors and proteinases. Most of them are in the solvent exposed loop. But P1 residue is the key active site of the interaction between inhibitor and enzyme. The types of the amino acid at P1 site likely play an important role in causing different inhibitory activity. The substitutions at the contact residues cause significant effects on the association constant. By using the Laskowski algorithm, the Ki values of a Kazal domain against six serine proteinases can be predicted from the domain' s sequence alone. At present there are many Kazal proteinase inhibitors found in the organisms, which show important biological functions. This article gives a comprehensive review of the newer developments in the characters and the interaction of the Kazal-type inhibitors.

Objective To investigate the clinical value of transient elastography in adult after liver transplantation,by means of evaluating the correlation of liver stiffness measured by FibroScan with liver/renal functions.Method Forty-three patients received orthotopic liver transplant in our hospital during Dec.10,2013 and Mar.19,2014 were included in this study.Liver stiffness measurement (LSM) was performed after transplantation.Clinical data and laboratory tests including liver function and renal function were collected and analyzed.Result Bivariate correlation showed that body mass index (BMI),MELD score,graft-to-recipient weight ratio (GRWR) and warm ischemia time had no correlation with LSM.LSM at the 1st day after transplantation (LSM-1) showed no correlation with cold ischemia time,but LSM at the 7th day after transplantation (LSM-7) did,with R =0.335,P =0.028.LSM-1 showed positive correlation with the ICU time (R =0.488,P =0.001),but LSM-7 didn't.There was significantly positive correlation between LSM and aspartate aminotransferase,bile acid and creatinine,but no significant correlations were found between LSM and alanine arninotransferase,alkaline phosphatase,cholinesterase,gamma-glutamyl transferase,total bilirubin,direct bilirubin,indirect bilirubin,urea nitrogen and uric acid.The group with higher LSM-1 had longer ICU time than the lower group (9 d vs,7 d,P =0.013),and so was the hospital stay (34 d vs.23 d,P =0.023).For the LSM-7,there was no significant difference in ICU time and hospital stay between the two groups.The group with higher LSM-1 had higher serious complication incidence than the lower group (78.57％ vs.27.59％,P =0.002),but the two groups in LSM-7 showed no significant difference in serious complication incidence.Conclusion The LSM partially correlates with the liver function and renal function of liver transplantation recipient,and may have its clinical value for assessing the early prognosis after liver transplantation.

Objective To examine the epidemiology of kidney stone in Pudong New Area ofShanghai and analyze its risk factors. Methods 12 565 residents with the age above 16 years weresurveyed. All subjects needed to answer a questionnaire concerning their sex,age,geographic loca tions,occupation,education status and family history of renal calculi,etc. Ultrasound examinationwas used to diagnose the kidney stone. Results The average prevalence of kidney stone was 3.15%(396/12565),4. 05%(247/6096)in the men and 2.30%(149/6469) in the women,respectively (P<0. 05). The prevalence increased significantly with age of men,whereas the prevalence was highest forwomen aged 50-59. The prevalence between city and rural was not significantly different before age60 (2.58% vs 2. 62%,P>0. 05),whereas the prevalence were significantly different after age 60(6.28% vs 3.36%,P<0.05). The prevalence of subjects with a family history of renal calculi washigher than that without family history (32.02% vs 2.06%,P<0. 01). The prevalence in manage ment staff and vehicle drivers were the highest. Conclusions The prevalence of kidney stone in Pud ong New Area of Shanghai was lower than that in south of China. The relative risk increased in sub jects of aged men,women aged 50 59,with family history of renal calculi,management staff and ve hicle drivers. An understanding of the epidemiology particularly the interactions among different fac tors,may help lead to approach that reduce the risk of stone formation.
