Objective To investigate the clinical significance of routine application of choledochoscope during operation of biliary duct.Methods The clinical data of 136 patients with the routine application of intraoperative choledochoscope dealing with bile duct diseases in this hospital from October 2003 to July 2009 were analyzed and summarized.Results Intraoperative choledochoscope inspection,taking stones and targeted surgery were performed in 116 cases with extrahepatic and (or) intrahepatic bile duct stones.The taking out rate of extrahepatic bile duct stones was 100% (85/85),the residual stone rates of extrahepatic and intrahepatic bile duct were 0 (0/85) and 22.6% (7/31),respectively,with the total residual stone rate was 6.0% (7/116).By using intraoperative choledochoscope,benign intrahepatic bile duct stricture was found in 13 cases,malignant extrahepatic and intrahepatic bile duct stricture in 8 cases.Four cases of hilar cholangiocarcinoma and 4 cases of common bile duct cancer,2 cases of lower segment of common bile duct polyp,3 cases of hepatolithiasis with the left hepatic bile duct carcinoma were diagnosed by biopsy via choledochoscope.Causes were confirmed by applying choledochoscope in 16 patients with obstructive jaundice.The use of choledochoscope with surgical treatment enabled benign and malignant bile duct stricture to achieve good results,without serious complications such as bile duct dilaceration,subphrenic abscess or acute cholangitis.Conclusions Using choledochoscope can tremendously reduce the residual rate of stone in biliary duct surgery,increase the definite diagnosis rate of biliary duct diseases and play a role of reasonable instruction in its treatment options.It has unique advantages in identifying causes of jaundice.It is remarkable that the role of applying choledochoscope to diagnose and cure biliary duct diseases.It should be widely used.

OBJECTIVE：To study the secretion of catecholamine primary cultures of chromaffin cells from rat adrenal medulla were used.METHOD:Catechoalmines(norepinephrine,epinephrine and dopamine) were measured by high-performance liquid chromatography-electrochemical detection technique.RESULTS:Catecholamine released by chromaffin cells with in 20min without slimalus was (73.29±15.32) ng/106 cells.When acetylcholine,nicotine or muscarine was added,the secretion of catecholamine was then increased.CONCLUSION:Using high-performance liquid chromatography-electrochemical detection technique,we can detect sensitively catecholamine released by cultured rat chromaffin cells.

BACKGROUND:Articular cartilage has limited ability to repair itself, and the traditional means are difficult to repair articular cartilage defects, but articular cartilage tissue engineering provides new methods and approaches for large-area articular cartilage defects. OBJECTIVE:To review the current status, problems and prospects of tissue engineering technology in articular cartilage repair. METHODS:The retrieval of PubMed database was performed for articles published from 1982 to 2015, with the keywords of “articular cartilage, repair, tissue engineering” in English. Literatures related to tissue engineering repair of articular cartilage were included, but repetitive studies were excluded. Finaly 39 articles were reserved in result analysis. RESULTS AND CONCLUSION:Excelent seed cels have chondrogenic differentiation potential, and currently, the main seed cels for articular cartilage repair include mesenchymal stem cels, embryonic stem cels, adipose-derived stem cels and precartilaginous stem cels. Different growth factors, which can induce the in vivo growth of host parenchymal cels, improve seeded cel stability, and accelerate tissue regeneration, tend to be combined in clinical application. Composite scaffolds are also one of hot researches that can promote cell inoculation and spatial distribution as well as accelerate cell proliferation. To obtain the best effectiveness of articular cartilage repair, how to optimize seed cells, select and match scaffold materials to construct new types of composite patterns is an important direction in the future.

The paper presents a detailed review of British pharmaceutical standards including British Pharma-copoeia, European Pharmacopoeia, British Approved Names, Reference Standards and Non-Statutory Pharmaceutical Standards. British pharmaceutical standards are established by the British Pharmacopoeia Commission, Expert Advi-sory Groups, Panels of Experts and Working Parties, British Pharmacopoeia Commission Secretariat, British Pharma-copoeia Laboratory, and standard-setting procedures are clear and definite. British Pharmacopoeia standards are le-gally binding, and pharmaceutical products sold in the United Kingdom must comply with pharmacopoeia require-ments. British pharmaceutical standards can serve as an important reference for reforms to China’s pharmaceutical standards, including the scientific management of pharmaceutical standards, the improvement of organizational frame-works in the establishment pharmaceutical standards, the promptness of amendments to pharmacopoeia, and the uni-versality of international exchanges.

Objective To evaluate the reliability and validity of Chinese multi-dimensional health assessment questionnaire (MDHAQ-C) in patients with systemic lupus erythematosus (SLE) in China.Methods One hundred and twelve SLE patients were recruited in the evaluation.The reliability of the questionnaire was tested by intra-class coefficient (ICC) and Cronbach's alpha.Convergent validity and divergent validity were assessed by Spearman correlation coefficient of MDHAQ-C with health assessment questionnaire (HAQ),the 36-item short-form health survey (SF-36) and the hospital anxiety and depression scales(HAD).Discriminant validity was tested in groups of patients with varied disease activities and status of damage.Results The Cronbach's alpha was 0.886 in the function scale (FN) and 0.774 in the scale of psychological status (PS).The corrected item-total correlation ranged from 0.409-0.866.The ICC was 0.615-0.920(P＜0.05).MDHAQ-C correlated with the questionnaires satisfyingly in most scales (from P＜0.5 to P＜0.001).The scores of MDHAQ-C could discriminate different groups of patients (P＜0.05).Conclusion MDHAQ-C is a reliable,valid instrument for functional measurement and quality of life assessment in Chinese SLE patients.

The financial compensation mechanism for public county hospitals are discussed and analyzed in the paper.Such a mechanism is analyzed by means of media coverage and literature consulting,along with field survey.Roadblocks have been found in implementation of the mechanism, namely delayed payment of capital expenditure compensation,poor support for medical equipment purchase,gaps in development key disciplines development,insufficient compensation for retirees expenses,poor definition of policy-incurred losses,and unclear compensation of public health services.in a word,it is imperative to change the unreasonable financial compensation mechanism,before the six financial compensation subsidies can be fully put in place and financial compensation made efficiently.
