Journal of Chinese Physician 2011;13(2):194-196
Objective To investigate the relationship between plasma visfatin levels and type 2 diabetes mellitus patients with carotid atherosclerosis.Methods 60 subjects were divided into 3 groups,T2DM no carotid atherosclerosis group (20 cases),T2DM with carotid atherosclerosis group (20 cases)and normal control group (20cases).Carotid IMT,plasma visfatin,waist circumference (WC),fasting plasma glucose (FPG),HbA1C,blood lipids,fasting serum insulin (FINS) were assayed or measured in all subjects.Results Plasma visfatin levels in T2DM with carotid atherosclerosis were significantly higher than those in normal control group and T2DM group [ (50.85 ± 20.14) ng/ml vs (18.50 ± 4.60) ng/ml,(50.85 ±20.14) ng/ml vs (35.52 ± 10.18) ng/ml,F = 105.983,P <0.01].Correlation analysis showed that plasma levels of visfatin were positively correlated with carotid IMT(r =0.476,P <0.01),TG (r =0.328,P <0.01),WC (r =0.206,P <0.05) and it was negatively correlated with HDL-C(r=-0.298,P <0.01).Conclusion Plasma visfatin was correlated with the development of macrovascular complications in T2DM patients,and it might be involved in the atherosclerotic pathological and physiological basis.
2.The Discussion on Standardization of Antimicrobial SusceptibilityTesting of Aquatic Pathogens
Microbiology 1992;0(04):-
Antimicrobial susceptibility testing (AST) is an important means to clinical microbiology. At present, there are no standard AST methods for aquatic pathogens comparing with human and veterinary pathogens. We reviewed the recent research progress on establishing these methods and discussed the key factors in AST of aquatic pathogens. Furthermore the defect of AST of aquatic pathogens in China was profiled and prospect for further research was put forward.

4.Antioxidant Effect of Selaginella Medicinal Plants and Its Quality Review
Herald of Medicine 2017;36(9):1010-1015
This paper aimed to introduce and review the antioxidant and material base of selaginella medicinal plants.On the basis of the systematic identification of selaginella medicinal plants,we found that the ethyl acetate extract and flavonoids could inhibit the activity of XOD,LOX or/and COX-2 to some extent.Fourteen biflavonoids,one flavonoid and five flavonoid glycosides have been isolated from three resource plants,among them five compounds were firstly reported and fifteen compounds were firstly isolated in selaginella plants.Amentoflavone (AME),robustaflavone and robustaflavone-4''-dimethylether are three common characteristic constituents of selaginella plants,which can act as marks of common active ingredients and be applied to evaluate the quality of selaginella.Further studies found that some plants had stronger anti-Coxsackie virus and anti-tumor effects,and their mechanisms were associated with inhibiting multiple oxidase and mitigating harm of free radicals due to whole function.

Objective To explore effects of comfort nursing on anxiety, depression and comfort of surgical patients.Methods Comfort nursing was done to 128 surgical patients, including physical comfort, psychological comfort and social comfort and self-designed questionnaire was made to investigate the comfort of patients during operation. When the patients were hospitalized and after operation, patients’physical states were evaluated with self-rating depression scale(SDS)and self-rating anxiety scale(SAS).Results The score of patients’comfort was (6.5±0.2)and the SDS and SAS were lower than that of patients when hospitalized with statistical difference(P<0.05).Conclusion Comfort nursing can reduce anxiety, depression and increase comfort of surgical patients.

This study is undertaken to modify the chitosan nanoparticles (CS-NPs) with wheat germ agglutinin (WGA), and investigate the conjugation between WGA-CS-NPs and N-acetylglucosamine (NAG). CS-NPs were prepared by ionotropic gelation process and then conjugated with WGA under the activation of glutaricdialdehyde. The mean diameter of the CS-NPs was approximately 113.5 nm and the poly-dispersity index (PDI) was 0.18. The binding yield of WGA to CS-NPs was comprised between 27.8% and 87.9% depending mostly on the addition of 0.3% (w/v) glutaraldehyde solution. A competitive inhibition experiment of WGA-CS-NPs to bovine submaxillary gland mucin (BSM) was taken to illuminate the binding activity of WGA-CS-NPs to the sugar of N-acetylglucosamine. After the addition of NAG, the binding rates between CS-NPs and BSM almost didn't change, while the binding rates between WGA-CS-NPs and BSM dropped down significantly, which confirmed the specific binding characteristics of WGA to NAG.

[Objective] The study was conducted to investigate the effect of micronized fenofibrate on acute insulin response in the subjects with impaired glucose metabolism and hypertriglyceridemia. [Methods] Fifty-three subjects were randomly (2:1 ratio) allocated to fenofibrate group (n=36, including IFG 3 cases, IGT 19 cases, IFG/IGT 6 cases, T2DM 8 cases) or control group (n = 17, including IFG 1 case, IGT 9 cases, IFG/IGT 4 cases, T2DM 3 cases) without any intervention for 3 months. Fasting blood samples were collected for measuring fasting plasma glucose (FPG), free fatty acids (FFA), and lipid profile. IVGTTs were carried out with measurement of plasma insulin before and after treatment. Acute insulin response (AIR), the maximum insulin concentrations (C_(INS,MAX)) to fasting insulin (FINS) ratio (C_(INS,MAX)/FINS) and values of the maximum insulin concentrations increment (△C_(INS)) during IVGTT were calculated as indexes of first-phase insulin secretion. HOMA insulin resistance index (HOMA IR) was used for assessing insulin resistance. [Results] After 3-month treatment, the lipid profile was evidently improved in fenofibrate group. Levels of trigiyceridemia (TG), low-density lipoprotein cholesterol and FFA were significantly reduced and high-density lipoprotein cholesterol increased significantly. Waist circumference was also significantly declined. No change of above indicators was found in control group. In fenofibrate group, C_(INS,MAX)/FINS and △C_(INS) were significantly increased (median 8.4 pmol/L vs. 5.3 pmol/L, 808±473 pmol/L vs. 660±472 pmol/L, both P<0.0001), along with great improvement of AIR (5 585±3 441 pmol·L~(-1)·min~(-1) vs. 4 444±3 642 pmol·L~(-1)·min~(-1), P<0.0001). The level of FINS and HOMA IR was also markedly reduced (108±65 pmol/L vs. 166±115 pmol/L, P = 0.002; 3.8±2.3 vs. 6.0±4.2, P = 0.001). In contrast, there were modest declining in acute insulin response (AIR: 4 313~1 943 pmol·L~(-1)·min~(-1) vs. 5 362±2 861 pmol·L~(-1).min~(-1); C_(INS,MAX)/FINS: median 4.6 vs. 7.0, P= 0.01; △C_(INS): 641±286 pmol/L, vs. 720±321 pmol/L, P= 0.003 9) and increasing HOMA IR (7.8±4.2 vs. 5.6±3.2, P<0.000 1) in control group after 3-month follow-up. The improvement of AIR was correlated with the decreasing of plasma FFA and TG (r=0.41, 0.36, P = 0.002, 0.014), but no correlation with the changing of FPG and HOMA IR. [Conclusions] These results indicated that sbort-term lipid-lowering treatment with fenofibrate evidently improved acute insulin response and alleviated insulin resistance in subjects with impaired glucose metabolism and hypertriglyceridemia. Moreover, the improvement of insulin secretion capacity may be mainly due to the relieving of iipotoxity resulting from finofibrate.

Thirty six patients with hypertriglyceridemia and impaired glucose regulation or newly diagnosed type 2 diabetes, whose fasting plasma glucose was ≤8.0 mmol/L, were treated by fenofibrate for 3 months. Lipid profile, insulin during intravenous glucose tolerance test and oral glucose tolerance test ( including glucose) were measured before and after treatment After treatment, lipid profile was significantly improved. Insulinogenic index (△I30/△G30) and acute insulin response were significantly increased (98. 9vs. 129. 2, 3558.9 vs. 4783. 3 pmol · L - 1 · min - 1, respectively, P < 0. 05 ). Fasting insulin and insulin resistant index in homeostasis model assessment ( HOMA IR) decreased ( 128. 6 vs. 84. 8 pmol/L, 4. 8 vs.3.0, respectively, P <0. 05 ). The improvement of insulin secretory function was more significant in patients with higher triglyceride (TG > 3. 3 mmol/L). These results indicate that short-term lipid-lowering treatment with fenofibrate can improve β-cell function and insulin resistance. Patients with higher triglyceride are likely to achieve more benefit from lipid-lowering treatment.
