Objective To study the effect of acarbose on vascular endothelial function in patients with impaired glucose tolerance (IGT).Methods Fifty-six cases with IGT were chosen by OGTT,and they were divided into control group(27 cases) and therapy group(29 cases) by systematic sampling.The patients in control group were received placebo,the patients in therapy group were given acarbose 25-50 rug,3 times daily for 12 weeks.The body mass index (BMI),blood fat,fasting blood glucose (FPG),fasting insulin (FINS),glycosylated hemoglobin (HbA1c),high sensitivity C-reactive protein (hs-CRP),von Willebrand factor (vWF),2 h post-meal glucose (2hPG),2 h post-meal insulin (2hINS) and brachial artery endothelium-dependent dilation (EDD) was detected before and after treatment in two groups.Results Compared with that before treatment,BMI,2hPG,2hINS,HbA1c,hs-CRP and vWF were decreased and brachial artery EDD was improved after treatment in therapy group[ (24.69 ± 2.62) kg/m2 vs.(22.02 ± 2.59)kg/m2,(9.26 ± 1.02) mmol/L vs.(7.43 ± 0.95) mmol/L,(42.17 ± 9.98) U/L vs.(34.76 ± 9.86) U/L,(6.03 ±0.67)％ vs.(5.37 ±0.56)％,(5.45 ± 1.93) mg/L vs.(4.52 ± 1.55) mg/L,(187.22 ±26.57)％ vs.(165.13 ± 23.86)％,(6.08 ± 1.22)％ vs.(7.94 ± 1.25)％ ] (P ＜ 0.05 or ＜ 0.01).There was no significant difference before and after treatment in control group (P ＞ 0.05).Conclusion Acarbose can improve brachial artery EDD in patients with IGT by increasing insulin sensitivity and decreasing postprandial hyperglycemia and inflammatory factor,which delays the progression of diabetic mellitus and atherosclerosis.

Choroidal neovascularization( CNV) is a common severe complication of ocular fundus diseases, with great potentiality to cause blindness. The treatments of CNV include photodynamic therapy ( PDT ) and anti-vascular endothelial growth factor( VEGF) therapy. However, PDT produces little visual benefits, and may result in ischemia, inflammatory responses, even the secondary expressions of VEGF. Anti-VEGF therapy sustained visual efficiency by repeated injections, causing economic burden and adverse effects related to injection. Recently, PDT combined with anti-VEGF therapy has progressed in laboratory and clinical research. Therefore, the combined modality therapy became one of the treatment options for CNV. In order to reduce the side effects of mono -therapy, further study is required to determine appropriate combinations and dosage.

This article discusses the necessity of the informatization construction and information of traditional Chinese medicine and its position and function in scientific research.Then from six aspects of infrastructure construction,information resource construction,information technology support,information personnel training,information and laws and regulations environment,and information resources product,this paper expounds the major tasks and constructive emphasis in each phase of scientific research informatization construction.Finally,this paper summarizes the prospect of TCM scientific research information construction and its role to the development of Chinese medicine.

B ased on Chinese medicine pharmacological literature data , the property , flavor , toxicity , meridian tropism, efficacy, and clinical application of Chinese herbal medicine were used as a set of attributes. The sup-port vector machine ( SVM ) was used in the establishment of predictive models of 187 pharmacological effects of Chinese herbal medicine respectively. And the cross-validation method was used to determine the accuracy of predictive models . After that , the predictive models with the predictive accuracy rate greater than 90% were used to predicate pharmacological effects of 624 herbals recorded in the Chinese Pharmacopoeia(2010 edition). It was found that the accuracy rate of 108 models was greater than 90%, and the accuracy rate of antibacterial effect predictive model was 99.76%. The highest predictive value of Chinese herbal medicine was the anti-oxi-dation effect of Menispermi Rhizoma.

Objective To validate the accuracy of the revised Atlanta classification (RAC) and the determinant-based classification (DBC) for severity of acute pancreatitis.Methods We retrospectively analysed the clinical data from 192 patients with acute pancreatitis who were admitted to our hospital between January 2014 and October 2014.Using the RAC and the DBC,The duration of total parenteral nutrition,length of ICU and hospital stay,operation rate and mortality were assessed in the subgroups,respectively.Results Fluid collections in and around the pancreas was present in 74 patients (38.5％),pancreatic or peripancreatic necrosis in 51 (26.6％),and infection in 18 (9.4％).On the basis of the RAC,106 patients (55.2％),77 patients (40.1％),and 9 patients (4.7％) were classified to have mild,moderately severe,or severe AP,respectively.On the basis of the DBC,11l (57.8％),62 (32.3％),14 (7.3％),and 5 (2.6％) patients were classified to have mild,moderate,severe,or critical AP,respectively.The different categories of severity for each classification system were significantly associated with the duration of total parenteral nutrition,the length of ICU and hospital stay,the operation rate and mortality.Conclusion Both the RAC and DBC accurately classified the severity of AP and differentiated prognosis in the subgroups of patients.

Objective To discuss the diagnostic value of serum cystatin-C(Cys-C) and urinary retinol binding protein(RBP) for the early renal impairment in multiple myeloma(MM) patients .Methods According to estimated glomerular filtration rate(eGFR) , the MM patients were divided into two groups :the normal renal function group(eGFR≥90 mL/min ,n=78)marked group A ,the renal impairment group(eGFR<90 mL/min ,n=40)marked group B .130 healthy subjects were selected as control group .The con-centrations of serum Cys-C ,urinary RBP ,serum creatinine(Cr) and serum urea nitrogen(UN) were measured and compared .Results The levels of Cys-C and RBP in group A were significantly higher than those in the control group(P<0 .01) .There were signifi-cant difference of the levels of Cys-C ,Cr ,UN and RBP levels between group B and control group(P<0 .01) .The sensitivity of the combined detection of Cys-C and RBP was 57 .69% ,significantly higher than single index test(P<0 .05) .Conclusion Compared with traditional biomarkers ,Cys-C and RBP are more sensitive and effective indexes for the diagnosis of early renal impairment in the patients with MM ,and jointed detection of the two biomarkers has important value .

This paper discussed the ethical principles in the medical sci-tech journal editing work, namely, respect, fairness, equality, honesty, and combining with the particularity of medical journals, further discussed these principles during choosing manuscripts, inviting manuscripts, peer review, rejection, and so forth. This pa-per proposed that medical journal editors should adhere to in the work of ethical principles, and constantly improve their ethics quality.

Objective To evaluate the changes of platelet aggregation rate and short-term prognosis after the application of colopidgrel with booster doses or replaced by ticagrelor for ACS patients with CYP2C19 medium-metabolized genotype). Method A total of 302 patients with medium-metabolized genotype were randomly divided into colopidgrel group (75 mg/bid) and ticagrelor group (90 mg/bid). Patients in both groups accepted other conventional treatments of coronary heart disease and accompanied diseases. The platelet aggregation rates and platelet inhibition rates were observed before and after the treatment. The incidence of adverse events was followed up within 1 m. Results After one-week treatment, the platelet aggregation rates of the inducement with 5 μmol/L ADP had statistical significance between colopidgrel group and ticagrelor group ( P = 0 . 019 ) and the platelet inhibition rates had statistical significance difference between the two groups (P = 0.000). No severe adverse events occurred within one-month follow-up and 10 dyspnea patients were all in ticagrelor group. Conclusions Compared with booster doses of clopidogrel, ticagrelor presents obvious inhibitory effect on platelet of patients with medium-metabolized of ACS but it increases the incidence of dyspnea.

Functioning gonadotroph adenomas (FGA) are pituitary tumors secreting biologically active gonadotropins.Because of its low incidence,it can be diagnosed only in evident clinical manifestations,and clinicians are often not able to make right diagnosis.The published literature includes only small case series or individual case reports.In this review,we will focus on the main presenting manifestations,the reported management options,and the long-term outcome of the FGA.
