OBJECTIVE:To investigate the effects of salvianolate combined with bezafibrate on clinical efficacy,inflamma-tory factors and ventricular function of patients with ischemic cardiomyopathy,and the safety. METHODS:A total of 138 pa-tients with ischemic cardiomyopathy selected from our hospital during Mar. 2015-Mar. 2016 were randomly divided into observa-tion group and control group according to random number table,with 69 cases in each group. Control group was given Bezafi-brate dispersible tablets 0.2 g,po,tid. Observation group was additionally given Salvianolate for injection 200 mg added into 0.9% Sodium chloride injection 250 mL,ivgtt,qd,on the basis of control group. A treatment course lasted for 14 d,and both groups received 2 courses of treatment. Clinical efficacies,the levels of serum inflammatory factors (CRP,TNF-α,IL-6, MMP-9,MCP-1),ventricular function parameters(LVESD,LVEDD,LVEF)were compared between 2 group. The occurrence of ADR was recorded. RESULTS:Total response rate of observation group(97.10%)was significantly higher than that of con-trol group(86.96%),with statistical significance(P<0.05). Before treatment,there was no statistical significance in serum lev-els of CRP,TNF-α,IL-6,MMP-9,MCP-1,LVESD,LVEDD and LVEF between 2 groups(P>0.05). After treatment,the lev-els of CRP,TNF-α,IL-6,MMP-9,MCP-1,LVESD and LVEDD in 2 groups were decreased significantly,while LVEF level was decreased significantly;the improvement of observation group was more significant than that of control group,with statisti-cal significance (P<0.05). No serious ADR was found in 2 groups during treatment. CONCLUSIONS:Salvianolate combined with bezafibrate have significant therapeutic efficacy for ischemic cardiomyopathy,reduce serum inflammatory factor level and improve ventricular function with good safety.

Based on previous report that the Chinese herb Ligustrum lucidum (LL) extract directly inhibited hepatitis C virus (HCV) replicase (NS5B) activity, the active components of LL extract to inhibit HCV NS5B activity and their inhibition mode were investigated in this study. LL extract was separated using ethyl acetate and thin layer chromatography (TLC). The inhibitory activity of separated fractions on HCV NS5B was analyzed by the inhibitory assay of NS5B activity. The results showed that only fractions 1 and 2 inhibited NS5B activity, and fraction 2 possessed higher inhibitory activity than fraction 1. HPLC analysis combined with inhibitory assays indicated that ursolic acid and oleanolic acid are the active components within fractions 1 and 2 to inhibit NS5B activity, separately. Moreover, oleanolic acid possessed higher inhibitory activity than ursolic acid. Further inhibition mode analysis found that both oleanolic acid and ursolic acid suppressed NS5B activity as noncompetitive inhibitors. The Ki values of ursolic acid and oleanolic acid were about 4.7 microg x mL(-1) (10 micromol x kg(-1)) and 2.5 microg x mL(-1) (5.5 micromol x kg(-1)), respectively. Taken together, these results demonstrated that oleanolic acid and ursolic acid suppressed NS5B activity as noncompetitive inhibitors, implying that the two natural products have potential value for HCV therapy.

Objective To evaluate the efficacy of Qingpeng ointment for the treatment of asteatotic eczema and its effect on skin barrier function.Methods A self-controlled clinical study was performed.Totally,78 patients with asteatotic eczema symmetrically located on both lower extremities were enrolled into this study.The left and right lower extremities of these patients were treated with Qingpeng ointment (Qingpeng group) and hydrocortisone butyrate ointment (hydrocortisone butyrate group) respectively,twice a day for 4 consecutive weeks.At the end of treatment,therapeutic effect and skin barrier function were compared between the 2 groups.Results The response rate was significantly higher in the hydrocortisone butyrate group than in the Qingpeng group after 1-and 2-week treatment (week 1:58.97％ vs.39.74％,x2 =5.77,P ＜ 0.05;week 2:76.92％ vs.60.26％,x2 =5.03,P ＜ 0.05),but insignificantly different between the 2groups after 4-week treatment (80.77％ vs.87.18％,P ＞ 0.05).Compared with the hydrocortisone butyrate group,theQingpeng group showed significantly increased water content of the stratum corneum after 4-week treatment (P ＜ 0.05),and decreased transepidermal water loss after 2-and 4-week treatment (both P ＜ 0.05).Conclusion Qingpeng ointment is safe and effective for the treatment of asteatotic eczema with gradually increasing and stable effects,and also has a favoring effect on the restoration of skin barrier function.

The effectiveness and safety of acupuncture combined with western medicine for angina of coronary artery disease are evaluated. Databases including Pubmed, Embase, Cochrane Library, CBMDisk,. CNKI, Wanfang, Chinese Clinical Trial Registry, etc. are searched with search time from beginning of the database establishment to January of 2014. As a result, totally 15 articles of acupuncture for angina of coronary artery disease that met the inclusive criteria were collected, involving 11 researches and 1 232 patients. The results of Meta-analysis indicate that based on regular western medicine, additional use of acupuncture could further improve symptoms of angina, increase efficacy of electrocardiogram (ECG) and reduce the dosage of nitroglycerin, in the meanwhile the hemorheology could be ameliorated, and the contents of C reactive protein (CRP), malondialdehyde (MDA), lipid peroxide (LPO), endothelin (ET) could be reduced, while the contents of superoxide dismutase (SOD) and nitric oxide (NO) could be increased; besides, the occurrence rate of cardiovascular event could be reduced without causing obvious adverse events. Except for certain outcomes (including dynamic ECG and blood viscosity) those have no statistical significance between treatment group and control group, the differences of remaining outcomes are: statistically significant. It is believed that acupuncture combined with regular treatment of western medicine are effective treatment plan for angina of coronary artery disease, which are superior to regular treatment of western medicine, but the results of this systematic review be taken with caution, and more clinical trials with high quality are looking forward to be included into Meta-analysis to increase the level of evidence.

Objective To investigate the incidence and risk factors of surgical site infection(SSI)in neurosurgical patients in a tertiary first-class hospital,and provide reference for the prevention and control of SSI.Methods 47 neurological patients with SSI (49 patients developed SSI,2 were excluded from study due to the lack of appropriate control subject)from December 31 ,2011 to December 31 ,2012 were as infected group,and 94 patients without SSI (1 ∶2 matching)were as non-infected group,risk factors for SSI were analyzed retrospectively.Results There was no significant difference in general condition of two groups of patients (all P >0.05 );among 3 708 patients,49 (1 .32%)developed SSI;intracranial infection was the main type of SSI (89.80%);27 patients were performed ce-rebrospinal fluid (CSF)bacteriological detection,6 (22.22%)of whom were positive for CSF bacteriological detec-tion.Univariate conditional logistic regression analysis showed that risk factors for SSI in neurosurgical patients were operational risk assessment score (OR =2.04),frequency of preoperative antimicrobial use(OR =3.15 ),fre-quency of intraoperative antimicrobial use(OR=2.58),duration of operation(OR=2.70),surgical blood loss(OR=1 .72),indwelling drainage tube(OR=4.30),duration of indwelling drainage tube after operation(OR=2.06),and time for initial dressing change(OR=1 .66);Multivariate conditional logistic regression analysis showed that the in-dependent risk factors for SSI were frequency of preoperative antimicrobial use(P =0.03,OR =4.86),duration of operation(P =0.05,OR = 2.89 ),and time for initial dressing change after operation (P = 0.01 ,OR = 1 .92 ). Conclusion Risk factors for SSI in department of neurosurgery are multiple,duration of operation,duration of in-dwelling drainage tube after operation,and time for initial dressing change after operation are major risk factors.

ObjectiveTo investigate the expression and significance of CD28- cells, CD4+ and CD8+T lymphocytes in the peripheral blood and synovial fluid in patients with rheumatoid arthritis ( RA ). Methods The expression of CD28, CD4+, CD8+ T lymphocytes and inducible co-stimulator(ICOS) in the peripheral blood and synovial fluid in 45 patients with RA were detected by three-color flow cytometry. Independent sample's t test was used for statistical analysis between the two groups. ResultsSynovial fluid CD4+CD28+ICOS+, CD4+CD28- ICOS+ , CD8 + CD28 + , CD8 + CD28 + 1COS+ T lymphocytes were significantly increased than the peripheral blood in RA patients[(36±19)％ vs (15±8)％, t=-4.234, P＜0.01; (2.1±2.2)％ vs (0.6±1.4)％, t=-3.143, P＜0.01; (62±15)％ vs (47±18)％, t=-2.885, P＜0.01; (9±9)％ vs (3±3)％,t=-2.131, P＜0.05], Synovial fluid CD8+CD28-T lymphoc-ytes were significantly reduced than the peripheral blood[(38±15)％ vs (54±18)％, t=2.975, P＜0.01], Synovial fluid CD8+ CD28-ICOS+, CD4+CD28+and CD4+ CD28- T lymphocytes had no significant difference than the peripheral blood (P＞0.05). Compared with peripheral blood in the same patients with RA, CD4+CD28+ ICOS+, CD8+ CD28+ T lymphocyteswere significantly increased[(38±18)％ vs (16±10)％, t=-4.065, P＜0.01 ; (61±16)％ vs (41±21)％, t=-4.065,P＜0.01], CD8+CD28-T was significantly reduced[(39±16)％ vs (59±21)％, t=2.949, P＜0.01]. The level of CD4+ CD28-, CD8+ CD28-, CD28-ICOS+ T lymphocytes in the active and remission patients with RA was not significantly different (P＞0.05). ConclusionSynovial fluid CD28T lymphocyte subsets disturbance and the abnormal expression of ICOS in patients with RA may play important roles in the mechanism of joint damage.

ObjectiveTo evaluate the adverse events occurred during tumour necrosis factor (TNF)-αblocker treatment in Chinese Han population patients with ankylosing spondylitis (AS).MethodsThis study had enrolled 369 Chinese Han population patients with ankylosing spondylitis.They all received TNF-αblocker treatment in the hospital.All 1011 administration were recorded in total.All of them were evaluated for adverse events 2 hours after injection,126 of them had received long-term TNF-α blocker injection,and they were followed-up at week 8,12,52,104.Mild immediate adverse events and long-term adverse events were all counted.SPSS 10.0 software package was used for Fisher's exact test.ResultsThree hundred and sixty-nine patients had 1011 administrations in total,652 had received rhTNFR:Fc,316 had infliximab,21had etanercept,22 had adalimumab injections.Adverse events 2 hours after injection were:17 (2.6％) for rhTNFR:Fc,12 (3.8％) for infliximab,0 for etanercept,1 (4.5％) for adalimumab.Twenty adverse events were mild(12 for rhTNFR:Fc,9 for infliximab),5 events were moderate(3 for rhTNFR:Fc,1 for infliximab,1 for adalimumab),4 events were severe(2 for rhTNFR:Fc,2 for infliximab).The frequency of adverse events were comparable between rhTNFR:Fc and Infliximab injection in immediate adverse reactions (P=0.31).One hundred and twenty-six (69 rhTNFR:Fc,57 infliximab) patients had long-term usage,and were followed-up at week 8,12,52,104,39 patients had adverse reactions:20 (51.3％) for rhTNFR:Fc,19(48.7％) for infliximab.Thirty-seven patients had infectious events(94.9％ ),1 neurological event(2.6％),and 1 patient had tuberculosis relapse (2.6％).Outcomes were comparable with rhTNFR:Fc and infliximab in long-term usage(P=0.69).ConclusionAttention should be paid to the above events in Chinese Han patients with ankylosing spondylitis who were treated with TNF-α blocker treatment.Special attention should be paid to those patients who are in their third or fourth injection.The occurrence of immediate reaction or long-term adverse events between rhTNFR:Fc and infliximab are comparable.

Objective To compare diagnostic values of the 2015 American Thyroid Association (ATA) Management Guidelines for Adult Patients with Thyroid Nodules and Differentiated Thyroid Cancer with the thyroid imaging reporting and data system (TI-RADS) for sonographic malignancy risk stratification of thyroid nodules.Methods From November 2011 to December 2015,485 thyroid nodules in 331 patients (mean age,42.9 years± 10.4)were included in this study.Characteristics includingsize,composition,shape(nonparallel or parallel),margin,echogenicity,calcifications and extrathyroidal extension of thyroid nodules were evaluated.Every nodule was stratificated by criteria set by TI-RADS and ATA guidelines,and malignant rate of each risk stratification were calculated and analysed.With pathology as the gold standard,different cutoff were taken to diagnose malignant nodules,and the sensitivity,specifity,positive predictive value,negativepredictive value and accuracy of the two methodologies were calculated at each cutoff.And the two methodologies were evaluated and measured by ROC curve.Finally their Kappa value were calculated at the best cutoff.Results Of the 485 thyroid nodules,96 were benign and 389 were malignant.The malignancy rates under TI-RADS category 2,3,4a,4b,4c,and 5 nodules were 0,12.0％ (3/25),22.2％ (10/45),29.8％ (14/47),99.2％ (261/363) and 100％ (101/101).Malignancy rates under ATA guidelines of benign,very low,low,intermediate,and high suspicion for malignancy were 0,12.5％ (1/8),16.1％ (10/62),27.7％ (13/47),and 99.2％ (365/368).There were significant differences inside each patterns (P ＜ 0.01) respectively and high correlation between risk stratification with TI-RADS (r=0.70) and ATA guidelines (r=0.83).Areas under the ROC curve of the TI-RADS and ATA guidelines classifications were 0.966 and 0.959.Best cut-off point for diagnosing malignant by TI-RADS and ATA guideline classifications were ≥ 4c and ≥ high suspicion,and at that point,diagnostic value of TI-RADS and ATA guidelines were nearly the same(sensitivity,93.1％vs 93.8％;specificity,97.9％ vs 96.9％;PPV,99.5％ vs 99.2％;NPV,75.7％vs 79.5％;and accuracy,94.0％vs94.4％),and there was no significant differences (P=0.50,P=0.50,P=0.50,P=0.53,P=0.55),Kappa=0.97.Conclusions Both TI-RADS and the ATA guidelinesprovide effective malignancy risk stratification for thyroid nodules.The diagnosticvalue of TI-RADS when considering ≥ 4c and ATA guidelines when considering ≥ high-suspicion nodules as malignant were nearly the same and both high.

Objective To investigate the relationship between the previous cesarean scar thickness, previous cesarean scar defect and the occurrence of uterine rupture for pregnancy women after previous cesarean section and to predict the occurrence of uterine rupture in the third trimester for pregnancy women after previous cesarean section by analyzing the lower uterine segment (LUS) situation or quantitatively measure LUS myometrium thickness. Methods A total of 154 pregnant women who have a prior cesarean from January 2015 to March 2016 were selected, all of them regularly did the prenatal examination in the pregnancy period and finally gave birth in hospital. By the transvaginal sonograph, the LUS myometrium thickness (transverse and longitudinal thickness) and the size of the previous cesarean scar defect were measured in the first trimester, the LUS myometrium thickness (longitudinal thickness) and qualitatively analysis LUS condition were measured in the third trimester. They were divided into two groups according to the pregnancy outcome: uterine rupture group (found in the cesarean operation or during the pregnancy) and without uterine rupture group (including the vaginal delivery women and those without uterine rupture in the cesarean operation period). The sensitivity and specificity of LUS myometrium thickness in the first trimester and the qualitative analysis LUS situation, the quantitative measurement of LUS myometrium thickness in the third trimester were compared in the prediction of occurrence of uterine rupture (dehiscence or complete rupture). Results The group without uterine rupture included 134 women (6 vaginal delivery and 128 cesarean delivery), and the group with uterine rupture included 20 women (all of them cesarean delivery). The LUS myometrium thickness in the third trimester in the group without uterine rupture was (1.6±0.5) mm, and was (1.1±0.7) mm in the uterine rupture group (P=0.004). There were no significant difference between two groups in the mean value of age, height, weight, the interdelivery interval, the LUS myometrium thickness (transverse and longitudinal thickness) in the first trimester. Qualitative analysis of LUS condition had higher specificity (99%), higher positive predictive value (92%), higher negative predictive value (94%) and slightly lower sensitivity (60%) than quantitative measure of LUS myometrium thickness in predicting uterine rupture. Conclusions Measurement of the LUS myometrium thickness in the first trimester is helpful for predicting the occurrence of uterine rupture, so it is not necessary to terminate the pregnancy because of the thin LUS or the little prior cesarean scar defect in the first trimester. However it should be paid close attention to the LUS situation during the whole gestation. Qualitatively analyzing LUS situation is more meaningful than quantitatively measuring LUS myometrium thickness in predicting the uterine rupture in the third trimester.
