Objective To analyze the training and evaluation standards on urine analyzers in the grass-roots medical unit.Methods The applicability,requirements,subject setup and items of the standards as well as the requirements of evaluation scoring chart were expounded in detail,and the related elementary knowledge was analyzed including the structure,working principle,installation and adjustment,operation,application,maintenance and etc of the analyzer.Combined personnel with the equipment was suggested to ensure the accuracy and high efficiency of the test result.Results The interpretation of the standards contributed to enhancing the quality of medical equipment training and the ability of practical support,and facilitated the examiner to perform annual evaluation with the scoring chart.Conclusion It is necessary to grasp accurately the connotation of the standards,to improve the quality of medical equipment training and to enhance combat support capability for the grass-roots medical unit and examiner.

Objective To investigate the relationship between the genetic variation of leptin receptor and obesity in Chinese population. Methods Genomic DNA was extracted from 50 obese subjects 〔Body mass index (BMI)≥30 kg/m 2〕 and 50 normal individuals (BMI

OBJECTIVETo evaluate the small fiber function in patients with type 2 diabetes mellitus of the early stage by measuring the sensory threshold with the quantitative temperature testing technology.

METHODSTwenty cases of patients with type 2 diabetes with no neurological deficit (DM group) and twenty age and sex-matched healthy controls underwent the detecting of cold sensory threshold (CST), warm sensory threshold (WST), cold pain threshold (CPT), heat pain threshold (HPT) in both inside of their hands.

RESULTSThere was no significant difference in CST, WST, CPT and HPT between left and right inside of hand of the same sample among all the testers. But the four kinds of threshold showed significant difference in the right inside of hand between patients and healthy people ( P < 0.05). In addition, the CST and WST differed significantly in the left inside of hand between the patients and healthy controls while the CPT and HPT showed no significant difference in the left inside of hand between them. Patients group and control group with CST and WST on the left side of the comparison difference was statistically significant (P < 0.05).

CONCLUSIONQuantitative analysis of temperature sense threshold can not only reflect increase of the pain threshold value, also can reflect its decrease, i. e. hyperalgesia, which may help to diagnose small fibrous peripheral neuropathy recognition, especially in early diabetic peripheral neuropathy.

BACKGROUND: The finite element method has been wildly used in stomatology,but,the modeling methods and models were different and lack of standard.There is not biomechanical analysis software which specialized indental implantology.OBJECTIVE: To compile software that can generate alveoli-implant complex finite element models.METHODS: Based on PC,CAD,finite element analysis,database and electronic table software,software that includes the functions of modeling,database and assembles was programmed using Visual Basic for Application programming language.RESULTS AND CONCLUSION: Various kinds of alveoli-implant models could obtain though the software.A software package that can generate alveoli-implant finite element models rapidly and automatically could be compiled with the complex of AutoDesk Mechanical Desktop 2009DX,ANSYS Workbench 10.1 and Visual Basic for Application.

ObjectiveTo explore the characteristics of violence behavior of the psychotics in communities. Methods37 psychotics who used to have violence behavior were investigated with Questionnaire of Characteristics and Associated Factor for Violence Behavior of Psychotics in Communities created ourselves. ResultsThe psychotics suffered violence behavior appeared some peculiarities for the time, place, and dealing with tools, etc. Their mental state, course of disease and treatment were associated with their violence behavior. ConclusionThere is some characteristics in most of the violence behavior of the psychotics, which may be helpful for preventing.

Aim To investigate the effect of Ding''s herb enema prescription on intestinal tissue related target in rat colitis induced by dextran sulfate sodium(DSS), and to elucidate the mechanism of Ding''s herb enema prescription in improving the intestinal inflammation and intestinal fibrosis.Methods Rats were fed with 3.5％ DSS.The rats were randomly divided into positive drug group, model group, Control group, and Ding''s herb enema prescription group.The positive drug group was treated with mesalazine enema, and Ding''s herb enema prescription group was treated with Ding''s herb enema prescription.The colon mucosa was taken once a day for 6 weeks.The changes of intestinal inflammatory response and intestinal fibrosis related proteins were detected by GSR-CAA-67 antibody protein array, and the differentially expressed proteins were screened out.Results Eight proteins showed statistical differences, including IFN-γ, erythropoietin(EPO), TIMP-2, TIM-1, IL-6, TIMP-1, TNF-α, IL-22 (P<0.05).On the other hand, Ding''s herb enema prescription and mesalazine significantly antagonized the effect of IL-6 and TIMP-1 (P<0.05).The antagonized effect of Ding''s embolization enema on TNF-α and IL-22 was also significant(P<0.05), but mesalazine had no similar effect (P>0.05).Conclusions Ding''s herb enema prescription has the effect of multiple targets, which may improve the intestinal inflammatory response and intestinal fibrosis to achieve the purpose of treatment of ulcerative colitis(UC).

Objective To assess and compare the effectiveness of gadolinium diethylenetriamine pentacetic acid(Gd-DTPA) solution and barium sulfate(BaSO4) suspension with different concentrations in improving the imaging quality of magnetic resonance cholangiopancreatography(MRCP). Methods The phantom study was carried out to determine the optimal concentration of Gd-DTPA and BaSO4 suspension used as an oral negative contrast agent in MRCP.The patients were grouped randomly and performed MRCP before and after using oral contrast agents in combination with intravenous injection of contrast agents.A comparison of the influence of BaSO4 suspension and Gd-DTPA with different concentrations on the signal intensity of the fluid in gastrointestinal tract on MRCP images was made.Results The phantom study showed that the dilution ratio 1∶10 of Gd-DTPA solution and 100%(W/V)BaSO4 suspension were the optimal concentrations in decreasing the signal intensity.In all patients the high signal intensity of the gastrointestinal fluid was completely suppressed after oral administration of Gd-DTPA diluted solution(P

Objective Through analyzing the epidemic characteristics and laws of human brucellosis in Gansu province during the past two years,to provide the basis for control of the disease. Methods Using China Information System for Diseases Control and Prevention V2.0 and survey data of human brucellosis outbreak,we calculated the incidence of brucellosis and the composition of new cases and chronic cases in 2009 and 2010, respectively, and analyzed the three distributions of the disease. Results Brucellosis incidence was 0.37 per million in 2009, and 1.7 per million in 2010. The new cases accounted for 54.6％(83/152) and 51.8％(43/83),and chronic cases were 53.3％ (81/152) and 56.6％ (47/83), respectively. About 1/3 of the counties (cities,districts) was found to be with the disease, and most cases were clustered in Hexi Corridor and Longdong area of Gansu province. There were three counties with outbreak. Time distribution of the disease was jagged. May, July,September and December were high, with September the highest. Sex ratio was 3 : 1, and mean age was 46 years old.67.7％ (159/235) of cases were farmers, followed by retired officers and herders, with a percentage of about 7％,respectively. Conclusions Epidemic of human brucellosis shows a rapidly rising trend in Gansu province. There are new patients throughout the year, and young farmers are the main victims. A high proportion of chronic brucellosis is more harmful. Strengthen the prevention and control of the disease to increase their brucellosis protective awareness.
