ABSTRACT
BACKGROUND@#Generic drugs are bioequivalent to their brand-name counterparts; however, concerns still exist regarding the effectiveness and safety of generic drugs because of small sample sizes and short follow-up time in most studies. The purpose of this study was to evaluate the long-term antihypertensive efficacy, cost-effectiveness and cardiovascular outcomes of generic drugs compared with brand-name drugs.@*METHODS@#In a multicenter, community-based study including 7955 hypertensive patients who were prospectively followed up for an average of 2.5 years, we used the propensity-score-matching method to match the patients using brand-name drugs to those using generic drugs in a ratio of 1:2, 2176 patients using brand-name drugs and 4352 patients using generic drugs.@*RESULTS@#There were no significant differences between generic drugs and brand-name drugs in blood pressure (BP)-lowering efficacy, BP control rate, and cardiovascular outcomes including coronary heart disease and stroke. The adjusted mean (95% confidence interval [CI]) of systolic BP (SBP)-lowering was -7.9 mmHg (95% CI, -9.9 to -5.9) in the brand-name drug group and -7.1 mmHg (95% CI, -9.1 to -5.1) in the generic drug group after adjusting for age, sex, body mass index, number of antihypertensive drugs and traditionally cardiovascular risk factors. Among patients aged <60 years, brand-name drugs had a higher BP control rate (47% vs. 41%; P = 0.02) and a greater effect in lowering SBP compared with generic drugs, with the between-group difference of 1.5 mmHg (95% CI, 0.2-2.8; P = 0.03). BP control rate was higher in male patients using brand-name drugs compared with those using generic drugs (46% vs. 40%; P = 0.01). Generic drugs treatment yielded an average annual incremental cost-effectiveness ratio of $315.4 per patient per mmHg decrease in SBP compared with brand-name drugs treatment.@*CONCLUSIONS@#Our data suggested that generic drugs are suitable and cost-effective in improving hypertension management and facilitating public health benefits, especially in low- and middle-income areas.

A series of berberine derivatives were synthesized by introducing substituted benzyl groups at C-9. All these synthesized compounds (4a-4m) were screened for their in vitro antibacterial activity against four Gram-positive bacteria and four Gram-negative bacteria and evaluated for their antifungal activity against three pathogenic fungal strains. All these compounds displayed good antibacterial and antifungal activities, compared to reference drugs including Ciprofloxacin and Fluconazole; Compounds 4f, 4g, and 4l showed the highest antibacterial and antifungal activities. Moreover, all the synthesized compounds were docked into topoisomerase II-DNA complex, which is a crucial drug target for the treatment of microbial infections. Docking results showed that H-bond, π-π stacked, π-cationic, and π-anionic interactions were responsible for the strong binding of the compounds with the target protein-DNA complex.

The relationship between the levels of renalase and changes in proteinuria,hypertension,renal function,renal tubular epithelial cell apoptosis and B-cell lymphoma-2 (Bcl-2) expression was investigated in patients (chronic nephritis,primary nephrotic syndrome or other kidney disease) that underwent renal biopsy.The study group comprised 72 patients undergoing renal biopsy.Patient profiles and renal function were collected.Concentrations of renalase and Bcl-2 were measured by immunohistochemistry.Tubular injury was detected by periodic acid Schiff staining (PAS) and renal tubular epithelial cell apoptosis was assessed by TUNEL assay.The expression of renalase was significantly lower in renal biopsy specimens than in normal kidney tissues.There was a positive linear relationship between renalase and some serum and cardiac indices;a negative correlation was found between age,eGFR,Ccr and 24-h urinary protein.Renal tubule injury index and tubular epithelial cell apoptosis index showed a negative linear correlation with renalase.The results showed that renalase probably increased the expression of Bcl-2.By two independent samples t-test,renalase levels were significantly increased in the non-hypertension group than in the hypertension group.One-way ANOVA showed that renalase expression was higher in samples with Lee's grade Ⅲ than in those with Lee's grade V.The expression of renalase was significantly decreased in patients who underwent renal biopsy,and was also associated with blood and renal function.The research proved that renalase may reduce renal tubular injury and apoptosis of renal tubular epithelial cells through the mitochondrial apoptosis pathway,finally achieving the purpose of delaying the progress of renal failure.

ABSTRACT
With the enhancement in the awareness of self-diagnosis among residents, it's very common for each family to prepare common medicines for unexpected needs. Meanwhile, with the popularization of the traditional Chinese medicine knowledge, the proportion of common traditional Chinese medicines prepared at residents' families is increasingly higher than western medicines year by year. To make it clear, both pre-research and closed questionnaire research were adopted for residents in Chaoyang District, Beijing, excluding residents with a medical background. Based on the results of data, a analysis was made to define the role and influence on the quality of life of residents and give suggestions for relevant departments to improve the traditional Chinese medicine popularization and promote the traditional Chinese medicine market.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the therapeutic effect of acupoint sticking therapy for treatment of stroke.</p><p><b>METHODS</b>Two hundred and forty-six cases were randomly divided into a non-acupoint sticking group (control group, n=122) and an acupoint sticking group (n=124). The control group was treated with routine ward treatment of stroke (acupuncture combined with routine western medicine). The acupoint sticking group was treated with basis ward treatment of stroke (similar to the control group), and acupoint sticking therapy was applicated on Shenque (CV 8). The scores of Stroke-Specific Quality of Life (SS-QOL) and WHOQOL-100BREF were adopted to evaluate the therapeutic effects and the cysteine of patients were tested before and after treatment.</p><p><b>RESULTS</b>There were significant differences in scores comparison of SS-QOL and WHOQOL-100BREF before and after treatment in both groups (both P < 0.001); there was no significant difference after treatment between two groups (P > 0.05); there was a significant difference in thinking items of SS-QOL after treatment between two groups (P < 0.05), the acupoint sticking group was superior to that of control group; SS-QOL score of patients with abnormal cysteine of acupoint sticking group was superior to that of the control group after treatment, with a significant difference between the two groups (P < 0.05).</p><p><b>CONCLUSION</b>The acupoint sticking therapy can improve the thinking ability of stroke patients, and improve the life quality of high cysteine stroke patients.</p>
