Effect of loureirin A against Candida albicans biofilms / 中国天然药物

Loureirin A is a major active component of Draconis sanguis, a traditional Chinese medicine. This work aimed to investigate the activity of loureirin A against Candida albicans biofilms. 2, 3-Bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT)reduction assay and scanning electron microscopy were used to investigate the anti-biofilm effect. Minimal inhibitory concentration testing and time-kill curve assay were used to evaluate fungicidal activity. Cell surface hydrophobicity (CSH) assay and hyphal formation experiment were respectively carried out to investigate adhesion and morphological transition, two virulence traits of C. albicans. Real-time RT-PCR was used to investigate gene expression. Galleria mellonella-C. albicans and Caenorhabditis elegans-C. albicans infection models were used to evaluate the in-vivo antifungal effect. Human umbilical vein endothelial cells and C. elegans nematodes were used to evaluate the toxicity ofloureirin A. Our data indicated that loureirin A had a significant effect on inhibiting C. albicans biofilms, decreasing CSH, and suppressing hyphal formation. Consistently, loureirin A down-regulated the expression of some adhesion-related genes and hypha/biofilm-related genes. Moreover, loureirin A prolonged the survival of Galleria mellonella and Caenorhabditis elegans in C. albicans infection models and exhibited low toxicity. Collectively, loureirin A inhibits fungal biofilms, and this effect may be associated with the suppression of pathogenic traits, adhesion and hyphal formation.

<p><b>BACKGROUND</b>Pharmacological therapy for congestive heart failure (CHF) with ventricular arrhythmia is limited. In the study, our aim was to evaluate the effects of Chinese traditional medicine Shensong Yangxin capsules (SSYX) on heart rhythm and function in CHF patients with frequent ventricular premature complexes (VPCs).</p><p><b>METHODS</b>This double-blind, placebo-controlled, multicenter study randomized 465 CHF patients with frequent VPCs to the SSYX (n = 232) and placebo groups (n = 233) for 12 weeks of treatment. The primary endpoint was the VPCs monitored by a 24-h ambulatory electrocardiogram. The secondary endpoints included the left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter, N-terminal pro-brain natriuretic peptide (NT-proBNP), New York Heart Association (NYHA) classification, 6-min walking distance (6MWD), Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores, and composite cardiac events (CCEs).</p><p><b>RESULTS</b>The clinical characteristics were similar at baseline. SSYX caused a significantly greater decline in the total number of VPCs than the placebo did (-2145 ± 2848 vs. -841 ± 3411, P < 0.05). The secondary endpoints of the LVEF, NYHA classification, NT-proBNP, 6MWD, and MLHFQ scores showed a greater improvements in the SSYX group than in the placebo group (ΔLVEF at 12th week: 4.75 ± 7.13 vs. 3.30 ± 6.53; NYHA improvement rate at the 8th and 12th week: 32.6% vs. 21.8%, 40.5% vs. 25.7%; mean level of NT-proBNP in patients with NT-proBNP ≥125 pg/ml at 12th week: -122 [Q1, Q3: -524, 0] vs. -75 [Q1, Q3: -245, 0]; Δ6MWD at 12th week: 35.1 ± 38.6 vs. 17.2 ± 45.6; ΔMLHFQ at the 4th, 8th, and 12th week: -4.24 ± 6.15 vs. -2.31 ± 6.96, -8.19 ± 8.41 vs. -3.25 ± 9.40, -10.60 ± 9.41 vs. -4.83 ± 11.23, all P < 0.05).

Effects of Acupuncture Therapy on Resting State Functional Magnetic Resonance Imaging in Patients with Ischemic Stroke / 中国中医药信息杂志

Objective To discuss the effects of acupuncture therapy on resting state functional magnetic resonance imaging (fMRI) in patients with ischemic stroke; To explore the central mechanism of acupuncture therapy.Methods Ten is chemic stroke patients with hemiplegia limbs and ten matched control subjects were included. Treatment group was given anti-platelet aggregation, anticoagulation, and nutrition brain cell therapy. At the same time, acupuncture therapy was given, taking Jianyu, Quchi, Shousanli, Waiguan, Hegu, Zusanli, Fenglong, Yanglingquan, Sanyinjiao, and Taichong, with even reinforcing-reducing method, and retaining the needle 30 min, manipulating needle every 10 min, once a day, 5 times a week, needle stopping for 2 d, for continuous 30 d. The health group did not undergo any treatment. BOLD-fMRI imaging technique was used, and based on RSET1.8 software, the parameters of brain activity before and after treatment were observed by amplitude of low frequency fluctuation (ALFF) method. The Results were compared with healthy group. Results Before treatment, the ALFF value of left caudate nucleus, putamen and globus pallidus in the treatment group was lower than that in the health group, and the ALFF value of bilateral precentral and postcentral gyrus, left grus frontalis superior, gyrus frontalis medius, gyrus temporalis medius and precuneus was higher than the health group (P<0.05). After treatment, the ALFF value in left caudate nucleus, putamen and globus pallidus in the treatment group was higher than that before treatment, and the ALFF value in left gyrus frontalis superior, gyrus frontalis medius and precuneus decreased than before group (P<0.05).Conclusion In the resting state of the ischemic stroke patients with hemiplegia limbs, the principal injured brain regions are caudate nucleus, putamen and globus pallidus.

Methylation in Promoter Region of SLC6A2 Gene in Heart Failure Patients and Its Correlation with Qi Deficiency/Blood Stasis Syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the methylation status in promoter region of norepinephrine transporter gene (NET, SLC6A2) in heart failure ( HF) patients and its correlation with qi deficiency/blood stasis syndrome (QDS/BSS).</p><p><b>METHODS</b>Thirty-six patients with heart failure (NYHA classification III to IV) were recruited in the study (as the heart failure group) and their scores of QDS/BSS were evaluated. Besides, a healthy elderly group (30 cases) and a healthy youth group (30 cases) were also set up. They were recruited from Physical Examination Center of Fujian Provincial Hospital. Pyrosequencing was applied to detect the methylation in promoter region of SLC6A2 gene, and the total methylation index (MTI) of CpG island was calculated. The correlation between the methylation status in promoter region of SLC6A2 and scores of QDS/BSS was assessed using Pearson and Partial analyses. Risk factors were screened and adjusted using Logistic regression.</p><p><b>RESULTS</b>By one-factor analysis of variance, the total MTI in the HF group (219.72% ± 54.03%) was obviously higher than that in the healthy elderly group (194.47% ± 34.92%) and the healthy youth group (161.60% ± 41.11%) (all P < 0.05). Meanwhile, the total MTI was higher in the healthy elderly group than in the healthy youth group (P < 0.01). By covariance analysis , after controlling age and BMI, the total MTI was higher in the HF group than in the healthy elderly group (P = 0.041), while it was higher in the healthy elderly group than in the healthy youth group (P = 0.016). Age was found to play an essential role in affecting MTI of SLC6A2 gene promoter region among the 3 groups (F = 16.447, P = 0.01). The total MTI was quite lower in the healthy youth group. Results of Partial correlation analysis showed MTI was positively correlated with scores of qi deficiency and blood stasis respectively (r = 0.494 and 0.419 respectively, both P < 0.05). Logistic regression analysis showed after adjusting confounding factors, the relative risk (OR value) of total MTI of SLC6A2 gene in promoter region was 1.038 (95% CI, 1.006 to 1.071, P = 0.020).</p><p><b>CONCLUSIONS</b>Abnormally elevated methylation of the promoter region of SLC6A2 gene is one of risk factors for HF. In addition, the degree of methylation of the promoter region of SLC6A2 gene was positively correlated with the severity of QDS/BSS.</p>

<p><b>OBJECTIVE</b>To observe clinical efficacy of plum-blossom needle for follicular maldevelopment (FM).</p><p><b>METHODS</b>Fifty cases of FM were randomly divided into a plum-blossom needle group and a medication group, 25 cases in each one. In the plum-blossom needle group, the plum-blossom needle was applied along Thoroughfare, Conception, Governor and Belt Vessel as well as at Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23), Luanchao (Extra), Zigong (EX-CA 1) during the follicular growth phase, once every other day. In the medication group, clomifene (CC) was prescribed for oral administration and human choriogonadotropin (HCG) was given by intramuscular injection, once each day. For both groups, one menstrual cycle constituted one course. After two courses of treatment, follicular development condition, the changes of endometrial thickness and morphology, ovarian resistent index (RI) and pulsatility index (PI), rate of ovulation and pregnancy were compared between the two groups.</p><p><b>RESULTS</b>After the treatment, the average diameters of the biggest follicle increased in both groups, while the endometrial thickness and morphology in the plum-blossom needle group were superior to those in the medication group (all P < 0.05). Ovarian RI and PI during mature follicular phase in the plum-blossom needle group were inferior to those in the medication group (both P < 0.05). The differences in ovulation and pregnancy rate were not significant statistically between the two groups (both P > 0.05).</p><p><b>CONCLUSION</b>The plum-blossom needle therapy based on regulating Thoroughfare, Conception, Governor and Belt Vessel could improve the ovarian blood perfusion, promote the follicular growth, increase the ovulation rate of mature follicle and avoid the out-of-sync between growth of follicle and endometrium during the treatment of western medication.</p>

Methodological quality assessment of systematic reviews correlated to traditional Chinese medicine published in China / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To assess the methodological quality of systematic reviews or Meta-analysis of traditional Chinese medicine published in China, and to validate the applicability of OQAQ (Overview Quality Assessment Questionnaire) and AMSTAR (a measurement tool to assess systematic reviews) in traditional Chinese medicine (Chinese Medical).</p><p><b>METHODS</b>Comprehensive literature retrieve was performed in CBM, CNKI, VIP as well as hand searching in Chinese Journal of Evidence-Based Medicine. The retrieve was started from January 1, 1999 and terminated by December 2008. The methodological quality of traditional Chinese medicine correlated systematic reviews was evaluated using OQAQ and AMSTAR simultaneously.</p><p><b>RESULTS</b>A total of 115 systematic reviews involved 17 types of diseases, of which, the cardio-/cerebrovascular diseases was dominant (36 papers, 31.30%). The mean OQAQ score was 2.50 (95% CI: 2.22, 2.76). No significant correlation was found in OQAQ score with publication year (P = 0.35) and different disease types (P = 0.28). High consistency was observed in evaluations of systematic reviews by using OQAQ and AMSTAR (both Kappa values > 0.75). Compared with the OQAQ, AMSTAR incorporated 3 additional items: the topics, publication bias, and conflict of interest, etc. Although 98.26% of systematic reviews proposed protocols in prior, 53.04% failed to analyze the publication bias. Besides, 57.39% neglected to address the potential conflict of interest.</p><p><b>CONCLUSIONS</b>Poor methodological quality in systematic reviews of Chinese Medical published in China needs to be improved and emphasized. It is necessary to integrate the special characteristics of traditional Chinese medicine itself when choosing topics of systematic reviews. It is essential to establish quality assessment tools targeting systematic reviews of traditional Chinese medicine.</p>

Effect of evidence-based medicine on the treatment of cardiovascular disease / 中华医院管理杂志

Evidence based medicine is not quite the same as traditional medicine, as the former stresses the combination of evidence and doctors experience, failure to achieve which will be disadvantageous to patients. In recent years, evidence based medicine has been growing silently in China. At present the ideology of evidence based medicine is being widely applied to the treatment of cardiovascular disease, including hypertension, arrhythmia, heart failure, myocardial infarction, etc. and the regulation of fat metabolism. Some medications harmful to patients have been discarded and curative effects have been improved. Of course, there are still some shortcomings. Yet evidence based medicine has also exerted an effect on people in the medical circle and the making of medical decisions.
