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 evaluate the effect of angiotensin Ⅱ (Ang Ⅱ ) on the change of nephrin phosphorylation both in Ang Ⅱ-infused rat model and cultured podocytes.Methods Thirty Wistar rats were subcutaneously embedded with osmotic minipumps and randomly divided into 3 groups according to receiving either Ang Ⅱ at a dose of 400 ng· kg-1· min-1 or Ang Ⅱ +telmisartan at a dose of 3 mg·kg-1 ·d-1,or normal saline as a control group.Blood pressure and 24-hour urinary albumin were measured at 0 d,7 d,14 d,21 d and 28 d of the experiment.Renal histomorphology was evaluated through electron microscopy.The concentrations of Ang Ⅱ both in blood plasma and kidney were detected by radioimmunoassay.In vitro,cultured murine podocytes were exposed to Ang Ⅱ (10-6 mol/L) pretreated with or without losartan (10-5 mol/L) for different time periods.Nephrin and its phosphorylation expression were analyzed by Western blotting.The distribution of F-actin was presented by FITC-phallodin labeling.The change in phenomenon of F-actin was evaluated by cortical F-actin score index (CFS).Results (1)Ang Ⅱ-infused rats exhibited increased Ang Ⅱ concentration,significant hypertension and marked albuminuria.(2)In Ang Ⅱ-infusion group,nephrin expression was decreased (P＜0.05).Ang Ⅱ-receiving rats displayed diminished phosphorylation of nephrin.(3)In vitro,the phosphorylation of nephrin was significantly reduced after Ang Ⅱ stimulation for 3-6 hours (P＜0.05).(4)Ang Ⅱ stimulatation resulted in irregularly arrangement of F-actin followed by the redistribution of F-actin to podocyte periphery and formation of F-actin ring,in which the CFS obviously increased compared to control (P＜0.05).Conclusions Phosphorylation of nephrin is important for the survival status of podocytes.Ang Ⅱ-induced nephrin dephosphorylation may be an important molecular mechanism for Ang Ⅱ-induced podocyte cytoskeleton rearrangement and foot process effacement.

Objective To compare the clinical efficacy and safety of isotretinoin erythromycin gel, a gel containing isotretinoin (0.05%) and erythromycin (2%), versus adapalene gel in the treatment of mild to moderate acne vulgaris. Methods A multicenter, randomized, open, parallel-controlled clinical study was conducted. A total of 192 patients with mild to moderate (Grade Ⅰ -Ⅲ ) acne vulgaris were enrolled in this study according to the grading criteria for acne severity in guidelines for the treatment of acne in China. Efficacy analysis was carried out in 169 patients and safety analysis in 190 patients. The patients were classified into trial group (n = 86) and control group (n = 83 ) to be treated with isotretinoin erythromycin gel or adapalene gel once a night for 6 weeks. Patients were evaluated at the baseline, on week 2, 4 and 6 during the treatment for the count of comedones (both open and closed), inflammatory papules and pustules, severity of acne and local or general adverse effects. Results After the start of treatment, the response rate gradually increased and severity of acne decreased in both groups. On week 6, the total response rate was 51.16% in the trial group and 40.96% in the control group (P ＞ 0.05), while a greater reduction in the count of pustules and inflammatory lesions was observed on week 4 and 6 in the trial group with a lower severity grade of acne compared with the control group (P ＜ 0.05 or 0.01 ). Adverse reactions were similar in both groups and manifested as tolerable local irritation. Conclusions The efficacy of isotretinoin erythromycin gel is similar to that of adapalene gel in the treatment of mild to moderate acne vulgaris, however, isotretinoin erythromycin gel seems superior to adapalene gel in reducing inflammatory lesions and rapidly improving severity of acne vulgaris.
