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.

At present, immune checkpoint inhibitors (ICIs) are widely used in clinical, and the common adverse reactions include adverse reactions of skin, gastrointestinal tract, endocrine and liver. Adverse reactions to the lungs and heart are relatively rare, but can be fatal. Systemic steroid therapy is the main treatment for immune related adverse events (irAEs). If there is no response to steroid therapy, an immunomodulator may be considered. Understanding the incidence, pathogenesis, common types and treatment strategies of irAEs can provide theoretical basis for the safe application of ICIs in clinical practice.

Objective To investigate the potential of the Clock Drawing Test (CTD) in differentiating the mild cognitive impairment (MCI) and Alzheimer's disease (AD). Methods Cognitive impaired patients admitted to the outpatient and inpatient of neurological department of our hospital from October 2011 to October 2013 were reviewed. There were 65 cases with MCI and 63 cases with AD. The scores of CDT were compared between them, and the sensitivity and specificity were evaluated with Receiver Operating Characteristic Curve. Results The MCI group and AD group matched in age, gender and education. The scores of Chinese version of the Mini-Mental State Examination and CDT were significantly defferent between the two groups. The sensitivity of 3-point CDT was 54.0% and the specificity was 80.9% in differentiating MCI and AD. Conclusion CDT is helpful to differentiate MCI from AD only in a set of assessment.

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.

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.
