This paper aims to find out the use status of medical and sanitary equipment in primary unit. By means of investigating grass-roots health institutions and summarizing practical works, such problems in equipment were detected as standard vacancy, datedness and laggardness, partly absence, nonstandard management, untimely maintenance and low rate of utilization, etc. This paper puts forward some suggestions corresponding to the above disadvantages.

Objective To investigate the effects of hepatocyte growth factor(HGF) on proliferation and collagen synthesis induced by angiotensin Ⅱ(AngⅡ)in SD rat cardiac fibroblasts(CFbs),and determine the role it plays in hypertensive ventricular remodeling.Methods CFbs in SD rat were cultured in vitro and treated with different concentrations of AngⅡ and/or HGF.Collagen type Ⅰ synthesis of CFbs was measured by Western blotting,and proliferation of CFbs was detected by MTT assay. Results AngⅡ promoted collagen synthesis and proliferation in CFbs in a certain concentration range,which can be significantly inhibited by HGF. ConclusionHGF can inhibit the proliferation and collagen synthesis induced by AngⅡin SD rat CFbs,and may protect against hypertensive ventricular remodeling.

Abstract： Objective　To investigate the relationship between plasma exosomal microRNA (miRNA)-346 and treatment outcomes in patients with multidrug-resistant tuberculosis (MDR-TB), to provide more reference basis for the treatment of MDR-TB patients. Methods　A total of 406 patients with MDR-TB admitted to Tuberculosis Control and Prevention Institute of Shaanxi Provincial between January 2018 and May 2021 were selected as the study subjects. General clinical data of the patients were collected and analyzed. The expression level of plasma exosomal miR-346 was detected by real-time fluorescence quantitative polymerase chain reaction. The predictive value of plasma exosomal miR-346 for treatment outcome was analyzed using receiver operating characteristic (ROC) curve analysis. Furthermore, the relationship between the expression of plasma exosomal miR-346 and treatment outcome was analyzed using a multivariable logistic regression model. After standard treatment, patients were divided into good treatment outcome group (n=226) and poor treatment outcome group (n=180) according to the treatment outcome. Results　Typical exosomes were identified by transmission electron microscopy, particle size analysis and Western blot, that is, plasma exosomes were successfully extracted. In the poor treatment outcome group, more patients were complicated with diabetes or HIV infection, and the proportion of patients with pulmonary cavity, acid-fast bacilli smear positive rate >1+, previous treatment history and fluoroquinolone resistance was also significantly increased, and the levels of white blood cells, neutrophils, and monocytes were significantly increased, while the level of albumin was significantly decreased, with statistical significance (P>0.05). Compared with the good treatment outcome group [0.61 (0.46, 0.74)], the expression level of plasma exosomal miR-346 in the poor treatment outcome group [1.23 (0.60, 2.02)] was significantly higher (Z=-13.185, P<0.001). ROC curve analysis showed that the area under the curve of plasma exosomal miR-346 to predict adverse outcomes of MDR-TB treatment was 0.881 (95%CI: 0.846-0.915), with a sensitivity of 78.3% and specificity of 86.7%. The corresponding cut-off value was 0.81. Multivariate logistic regression analysis showed that diabetes, AIDS virus infection, pulmonary cavity, AFB smear positive degree>1+, previous treatment history, fluoroquinolones resistance and high expression of plasma exosomal miR-346 were independent influencing factors for poor treatment results of MDR-TB (P<0.05). Conclusions　High expression of plasma exosomal miR-346 is associated with the high risk of adverse outcome of MDR-TB treatment, and it is promising to be a useful marker for predicting the outcome of MDR-TB treatment.

OBJECTIVETo explore an effective method for increasing therapeutic effect on chronic prostatitis.

METHODSEighty-two cases of chronic prostatitis were randomly divided into two groups. The western medicine group of 42 cases were treated with routine western medicine combined with retention enteroclysis of 30 g Danshen (Red Sage Root) decoction; the warming needle moxibustion plus western medicine group of 40 cases were treated with the western medicine of the western medicine group plus warming needle moxibustion at Guanyuan (CV 4), Qihai (CV 6) and Zhongji (CV 3), etc.

RESULTSIn the warming needle moxibustion plus western medicine grbup, 20 cases were cured, 12 cases were markedly effective, 5 cases were effective and 3 cases were ineffective, the total effective rate being 92. 5%; and in the western medicine group, the corresponding figures were 13, 10, 7, 12 cases and 71.4%, with a significant difference between the two groups in the total effective rate (P < 0.05).

CONCLUSIONWarming needle moxibustion can increase the therapeutic effect on chronic prostatitis.

ObjectiveTo establish a method for content determination of total iridoid compounds and baldrinal and 11-ethoxyviburtinal from Valerianae Jatamansi Rhizoma et Radix; To determine the contents of total iridoid compounds and baldrinal and 11-ethoxyviburtinal in Valerianae Jatamansi Rhizoma et Radix from three medicinal origins.Methods UV spectrophotometry was applied, 11-ethoxyviburtinal (cyclopentane-pyran-7-formaldehyde, 4-ethoxy methyl) was set as the reference substance, and the content of total iridoid compounds was determined at 288 nm. HPLC method was used to simultaneously determine the contents of baldrinal and 11-ethoxyviburtinal. The HPLC analysis was performed on a Phenomenex Luna C18 column (250 mm×4.6 mm, 5μm). The mobile phase was composed of acetonitrile-water in gradient elution at a flow rate of 0.95 mL/min. The detection wavelength was 288 nm and the column temperature was 30℃.Results The total iridoid compounds, baldrinal and 11-ethoxyviburtinal were in good linearity within the ranges of 2.088–14.616μg/μL, 74.88–224.64μg, and 41.6–249.6μg, respectively. This method was precise, and with good repeatability, stability and recovery rate.Conclusion The method is accurate, simple, rapid, which can be used for the quality control of Valerianae Jatamansi Rhizoma et Radix.
