OBJECTIVE: To study the effects of Tangmaikang granules on blood sugar and sugar tolerance in diabetic mice and on the sugar tolerance of normal rats.METHODS: The diabetic mouse model was induced by alloxan,and the effects of different dosage of Tangmaikang granules on blood sugar and sugar tolerance in experimental diabetic mice and on the sugar tolerance of normal rats were observed.RESULTS: Tangmaikang granules(Medium-dose and high-dose) could downregulate the blood sugar level of experimental diabetic mice and inhibited the glucose-induced increase of the blood sugar level,showing significant differences as compared with the model group(P

Pancreatic cancer is a kind of high degree of malignant gastrointestinal tumor,and its incidence has increased significantly in recent years.Due to the low early diagnosis rate,and the extreme low middile or late resection rate of pancreatic cancer,Pancreatic cancer's prognosis is poor.Therefore,improving the early diagnostic rate of pancreatic cancer has very important significance for improving the prognosis.Early diagnosis of pancreatic cancer is dependent on tumor markers detection to a great extent.And proteomics progress rapidly in recent years and has been widely applied in clinical research.It provides an effective way to find markers.Among all of the spec imens,secrum is easy to obtain,and it allows repetitive detection.What is more,secmm is also renewable.So it is the most ideal for biological specimens.In this review,the proteomics technology role in pancreatic cancer patients serum detection were summarized.

Objective To investigate the relationship of the level of serum C-peptide(C-P)with albumin-to-creatinine ratio(ACR)and nerve conduction velocity(NCV)in patients with T2DM.Methods The study included 132 patients with T2DM and 30 healthy controls.The NCV,ACR,fasting C-P and C-P at 2hOGTT(FC-P and 2hC-P)and plasma glucose(PG)were measured.The patients were separated into three groups of Ⅰ(45 cases),Ⅱ(52 cases)and Ⅲ(35 cases).The patients were further classified into two groups of normal NCV(70 cases)and abnormal NCV(62 cases).Results ①The differences of FC-P and 2hC-P among the ACR groups were significant(all P<0.05).②The ACR was correlated with course,2hC-P,2hPG significantly(all P<0.01).The sequence of the impact degree on ACR was from course(Beta:0.592)to 2hC-P(Beta:-0.297)and to 2hPG(Beta:0.201).③The levels of serum 2hC-P were significantly and gradually decreased in the groups of NCV(P<0.01).④The serum 2hC-P concentration was associated with ACR and NCV in different stages(P<0.01).Conclusions ①The level of serum C-P is tightly correlated with the vascular and neural dysfunction in T2DM.②Course,2hPG and 2hC-P may be the risk factors for ACR

Objective To study the quality control of yinpian of Isatis Root.Methods Optical microscope was used to identify the microscopic features,TLC was adopted to identify the arginine in Isatis Root,and HPIC-ELSD was used to detect the quality of arginine.Results and Conclusion There is no difference between yinpian and crude powder of Isatis Root.Arginine can be detected bv TLC.The moisture contents.the total ash contents and the acid-insoluble ash contents in the yinpian should be less than 9.0%,10.0%,and 2.0% respectively;while the alcohol-soluble extractive contents and the contents of arginine in Isatis Root should be more than 25.0% and 2.01% respectively.

The degradation kinetics of chlorogenic acid (5-CQA), cryptochlorogenic acid (4-CQA), and neochlorogenic acid (3-CQA) in aqueous solution at 37 degrees C and different pH values (7.05, 7.96, 9.25) were investigated in the present work. The results indicated that 3-, 4- and 5-CQA tended to remain stable in acidic pH circumstance, and unstable in neutral and alkaline pH circumstance. With the increase of the alkalinity, the degradation of 3-, 4- and 5-CQA was increased leading to a less amount of total CQA and was satisfactorily described by the Weibull equation. Meanwhile, caffeic acid was not detected after the degradation of CQA. Moreover, the degradation of 3-CQA and 5-CQA tended to be converted to 4-CQA, and the degradation of 4-CQA tended to be converted to 3-CQA rather than 5-CQA. The comparison of the degradation kinetics parameters of 3-, 4- and 5-CQA at neutral and alkaline pH values showed that the orders of the rate constant (k) values were 4-CQA > 3-CQA > 5-CQA, while the orders of the degradation half life (t½) values were 4-CQA < 3-CQA < 5-CQA, indicating the orders of the stabilities of 3-, 4- and 5-CQA at 37 degrees C and neutral and alkaline pH values were 4-CQA < 3-CQA < 5-CQA.

Objective To analyze the demographic characteristics,composition characteristics as well as influencing factors of the cost of hospitalization of patients with lung cancer in Gansu Province in order to help reduce their expenses. Methods The basics,healthcare records and expenses of patients diagnosed with lung cancer in a third-level grade-A hospital in Lanzhou were extracted between 2010 and 2014 through the hospital information system(HIS)database.The Wilcoxon rank-sum test was used to analyze the difference of expense composition over the past five years and the difference between subgroups.The forward,backward and stepwise selection method was used to select variables and the multi-linear regression analysis was adopted to explore the influencing factors of the cost of hospitalization.Results A total of 2778 eligible lung cancer patients were collected.The statistical analysis showed that western medicine cost (36.39%)and treatment cost (22.46%)accounted for the most of the total expense.The length of hospital stay was the No.1 influencing factor of the cost of hospitalization,followed by the acceptance of surgery,the year of admission and charge type. Conclusion Regulating drug use,enhancing treatment regimens,giving psychological guidance,strengthening hospital management and improving medical resources allocation may be effective measures to reduce the cost of hospitalization and lighten the economic burden for lung cancer patients in Gansu Province.

Objective In this study, the best domestic digestive departments' websites are evaluated, adopting the meth-od of cross-sectional descriptive research, to evaluate the quality of such sites, and describe their characteristics. Methods Using a pre-defined evaluation standard, two well-trained evaluators independently explore and analyze 10 websites of domestic best departments of digestive diseases. Selection of departments is based on a domestic au-thoritative released rank of the best departments which has high credibility. Results These sites perform well in the content, perform in function and design, but perform not well in management & maintenance. Conclusion As the public use the websites of professional websites more and more to obtain information and services, domestic best di-gestive departments should better their sites' quality to meet the growing demands of consumers.

Cardiovascular and cerebrovascular diseases have be-come a great health threat.Increasing evidence has shown that both asymmetric dimethylarginine (ADMA)and symmetric dim-ethylarginine (SDMA)play important and independent roles in the development of cardiovascular and cerebrovascular diseases as well as in the prediction of cardiovascular and cerebrovascular events.Alanine-glyoxylate aminotransferase 2 (AGXT2 )is re-cently observed to be involved in ADMA metabolism.Deficiency in the expression and activity of AGXT2 may thus play a role in the development of cardiovascular and cerebrovascular diseases by affecting ADMA levels in vivo.Several single-nucleotide poly-morphisms at AGXT2 locus are observed to be associated with plasma SDMA level.This review summarizes recent advances in AGXT2 and its role in ADMA metabolism and the clinical rele-vance.

The clinical data of 192 patients undergoing endoscopic thyroidectomy via thoracic and mammary approach from June 2010 to July 2015 were retrospectively analyzed.Tunnel bleeding occurred in 11 cases (hemorrhage group),which was associated with the incorrect level of puncture(P ＜ 0.01).The tunnel bleeding was stopped by percutaneous packet-suturing in all 11 cases.There were no significant differences in postoperative drainage [(65.4 ± 7.5) and (63.8 ± 7.1) ml],subcutaneous petechiae [1/11 and 1.1％ (2/181)],nursing costs[(135 ±20) and(132 ± 16) yuan],postoperative hospital stay[(4.5 ± 1.6) and (4.4 ± 1.3) d] and rehemorrhage [0/11 and 0.6％ (1/181)] between hemorrhage and nonhemorrhage groups.The results show that percutaneous packet-suturing is reliable and effective method for tunnel bleeding without additional postoperative complications.
