OBJECTIVE:To provide reference for the rational drug use and glycemic control for patients with type 2 diabetes. METHODS:160 patients with type 2 diabetes in 3 communities of Tianjin were divided into 2 groups based on the understanding of the diabetic knowledge,group A(86 cases)had understanding of diabetic knowledge and group B(74 cases)had no. They were carried on the questionnaire survey about the general information,medication and glycemic control. RESULTS:A total of 160 ques-tionnaires were conducted,and 160 were effective with the effective rate of 100%. The proportion of patients with highly educated (college or above)in group A was significantly higher than group B,low education(secondary or below)was significantly lower than group B(P<0.05). The proportion of patients with medicine background in group A was significantly higher than group B(P<0.05). There were no significant differences in the use ratio of different types of drugs for diabetes between group A and group B (P>0.05),however,the use ratio of self-purchase functional food in group A was 0,and group B(60.8%)was significantly high-er than group A(P<0.05). The recent self-test average blood glucose levels,the average blood glucose levels in the investigation day,the 2 h postprandial blood glucose and glycosylated hemoglobin levels in group A were significantly lower than group B(P<0.05). CONCLUSIONS:The medication and glycemic control of patients with type 2 diabetes is closely related to the understand-ing of glycemic knowledge. Therefore,propaganda and education of medication and related functional food for patients need to be strengthened to promote the rational medication.

Observing the clinical curative effect of orthopedics lotion to treat traumatic ankle arthritis, the outpatient department of orthopedics in Guang'anmen Hospital collected 60 cases who were diagnosed as traumatic ankle arthritis. The cases who already met the inclusion criteria, were randomly divided into the treatment group (30 cases) and control group (30 cases). Thirty patients in treatment group were received fumigation treatment with orthopedics lotion; 30 patients in control group were treated by intra-articular injection of sodium hyaluronate. After 5 weeks treatment, the effects on the both groups would be observed and analysed. Baird-Jackson scoring system was used to assess the overall curative effect. Visual analogue scales (VAS) was used to assess analgesic effect. BJ scores of pre-treatment and post-treatment in both the treatment group and the control group were compared, P <0O. 01, significantly different; and the BJ scores after treatment of two groups were compared by paired t-test, the t value is 1. 76, there was no significant difference between two groups. Both of the treatments were effective, but there was no significant difference in overall curative effect between the two kinds of treatment. The VAS scores after treatment of two groups were compared by paired t-test, the t value was 2. 282, and there was a significant difference between two groups (P <0. 05). The analgesic effect shown in treatment group was better than the control group. The results suggest that: orthopedics lotion is a effective way to treat traumatic ankle arthritis, and it has significant effect on analgesic.

OBJECTIVE: To discuss the biosafety and biocompatibility of biomaterials. METHODS: A computer-based online search of CNKI, CBM and VIP as well as manual search were performed to collect articles about random cell control experiments and animal experiments of biological material biocompatibility published between 1990 and 2008. A total of 28 Chinese literatures were collected, and 7 were included mainly involving the cytotoxicity test methods and blood compatibility of the experimental medium, experimental grouping, experimental materials, methods of observation, experimental results, and experimental conclusion. In addition, biocompatibility of the biological material was analyzed to summarize the biocompatibility of the biological safety. RESULTS: Based on experiments of biosafety and biocompatibility of biomaterials, the cytotoxicity test and blood compatibility of various biomaterials, such as collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, are essential for the biological safety. The experimental results have shown that the biomaterials have good biocompatibility. CONCLUSION: A variety of biological materials present good biocompatibility, including collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, based on the evaluation criteria.

Objective To investigate the effects of platelet-derived growth factor(POGF),basic fibroblast growth factor(bFGF)and epidermal growth factor(EGF)on the proliferation,migration and phenotypie modulation of airway smooth muscle cells(ASMCs)in vitro.Methods Cultured human ASMCs were stimulated with PDGF.bFGF,EGF or DMEM(control).Cell pmliferation was detected by BrdU incorporation and cell count.Cell migration was measured using Boyden's chamber.Reverse transcription-poly-merase chain reaction(RT-PCR)and Western blot analysis were used for the detection of sm-α-actin and sm-MHC mRNA and protein expression in ASMCs.Resuits The mitotic index(%BrdU-positive per total number of cells)of ASMCs stimulated with PDGF.bFGF and EGF were significantly higher than those in control(P<0.001 or P<0.05).And the cell number of ASMCs stimulated with PDGF,bFGF and EGFwere also significantly higher than those in control(P<0.05).The number of migrating cells treated with PDGF,bFGF and EGF were higher than that in eontrol(P<0.05).The expressions of sm-α-actin mRNA treated with bFGF and EGF were significantly lower than those in control.but it was higher than control when treated with PDGF.The expressions of sm-MHC mRNA treated with bFGF and EGF were significantly lower than those in control,but it was higher than control when treated with PDGF(P<0.01 orP<0.05).Theexpressions of sm-α-actin protein treated with bFGF and EGF were significantly lower than those in control,but it was higher than control when treated with PDGF(P<0.05).The expressions of sm-MHC protein treated with bFGF and EGF were significantly lower than those in control.but it was higher than control when treated with PDGF(P<0.05).Conclusion PDGF,bFGF and EGF can directly induce ASMCs,proliferation and migration in vitro;and meanwhile,the expressions of cells,contractive phenotype increased treated with PDGF and decreased treated with bFGF and EGF.

BACKGROUND: The parameters of blood platelet(B-PLT) can reflect its thrombo-function, but the variation of blood-platelet parameters in patients with thrombotic disease is controversial and not unanimous.OBJECTIVE: To observe the changing rule of the B-PLT parameters in patients with cerebral infarction(CI), and investigate whether blood cell counter can be used in the evaluation of the variation of B-PLT parameters in CI patients.DESIGN: A case-control and experimental study based on patients and healthy people.SETTING: Department of laboratory and internal medicine in a university.PARTICIPANTS: During the January and March 2002, 37 CI patients including 28 males and 9 females aged 45 - 87 years were selected from Department of Neurology, Union Hospital Affiliated to Tongji Medical College,Huazhong University of Science and Technology. Among 37 healthy people,20 males and 17 females aged 40 - 60 years were selected as control group.METHODS: Platelet distribution width (PDW), mean platelet volume (MPV), platelet-large cell ratio(P-LCR) and the changing quantity of B-PLT of 37 CI patients were analyzed with blood cell counter, meanwhile,the healthy people were analyzed as control subjects.MAIN OUTCOME MEASURES: Changes of B-PLT parameters in two groups respectively.RESULTS: A positive relation between PDW and P-LCR was observed and between P-LCR and MPV as well( r = 0. 99, 0.92, P ＜ 0. 001 ). A negative correlation between B-PLT quantity and MPV was observed and also between B-PLTquantity and P-LCR(r= -0.58, -0.59, P ＜0.05) .In CI patients, PDW, MPV and P-LCR were(14.51 ± 2. 88)%, (10.95 ± 1.48) fl and(34.24 ± 11.23)% respectively, which were higher than those of healthy people [ (12. 86 ± 2.02)%, (10. 19 ± 1.29) fl, (28.47 ± 9.41 )% ]respectively, and the difference was significant( P =0. 019 31, 0. 021 77 and 0.026 35), but there was no significant difference between the two groups in B-PLT quantity.CONCLUSION: The blood platelets' parameters in CI patients, which reflect the function of the B-PLT, are significantly higher than those in healthy people. It shows that the enhanced function of platelet is a risk factor of cerebral infarction, the use of blood cell counter in analysis can observe the variation of the platelets' function rapidly and accurately. It can be a useful method of the therapy and prevention in CI patients.

Chickenpox is an acute and highly infectious respiratory disease commonly seen in children.Varicela－zoster often results from the activation of latent virus in chickenpox called varicella－zoster virus（VZV）or called human herpesvirus type 3. Primary infection of VZV may induce typical disease of various severity and most healthy children infected with VZV have mild symptoms and good prognosis.But VZV infection，if occurs in special population such as persons of immune inhibition treatment will induce serious consequence or even death and it is as same serious as in adults.A detailed illustration of molecular biology，epidemiology，laboratory diagnosis，treatment and preventive strategy of the VZV were given.
