MicroRNAs (miRNA) plays an important role in biological development and disease occurrence and development, and acts as a "main switch" in biology. Among patients of essential hypertension, around 1/3 would suffer left ventricular hypertrophy (LVH). Hence, essential hypertension becomes an independent risk factor for cardiovascular diseases. And miRNAs plays an important role in the occurrence and development of LVH. This paper reviewed the role of miRNA in regulating the stress signaling pathway, defined its impact on the occurrence of LVH, and further emphasized the opportunities and challenges of miRNA as a biomarker and therapeutic target.

The methyl group plays an important role in the rational drug design. Introducing methyl into small molecules has become an important strategy of lead compound optimization. The application of methyl in drug design is reviewed in this paper. Methyl can modulate the physicochemical, pharmacodynamic, and pharmacokinetic properties by ortho effect, inductive effect, and conformational effect. It also improves the metabolic stability as a soft metabolic point. In addition, introducing methyl into drug molecules can also be applied as a strategy in new uses of old drugs and generate me-too drugs.

Objective To compare negative expiratory pressure (NEP)technique with conventional test in detecting expiratory flow limitation (EFL)in chronic obstructive pulmonary diseases( COPD) patients. Methods EFL was measured with NEP technique and conventional method respectively in 72 COPD patients;EFL was measured with NEP technique in 20 COPD patients who failed to perform conventional test. Results EFL was detected in 54 of the 72 COPD patients. NEP test was successfully performed on the 20 patients, and 19 of them were found with EFL. The level of forced expired volume in one second percentage( FEV_1 % ) of the patients with 2-score group (46. 92 ± 12. 74) % and 3-score group (33. 35 ± 8.96)% were significantly lower than that of the 1-score group(63. 60 ±16.65)%. Area under curve of NEP technique and conventional test in ROC is 0. 903 and 0. 761 respectively. Conclusions As compared with conventional test, EFL detected with NEP technique is more reliable in evaluating dyspnea of COPD patients. It is simple and doesn't require any cooperation of the patients. NEP technique can be applied in COPD patients who fail to receive conventional test.

Objective:To observe the clinical effect of mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus for deglutition disorder of stroke patients in convalescence stage.Methods:A total of 136 patients conforming to the inclusion criteria were randomized into three groups by the random number table,including group A of 46 cases,group B of 44 cases and group C of 46 cases.Patients in group A received swallowing disorder therapeutic apparatus treatment,patients in group B received mind-refreshing and orifice-opening needling method treatment,and patients in group C received mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus treatment.The treatment was given once a day for 10 d as a course,the whole treatment lasted for 4 courses.Therapeutic evaluation items including water-swallowing test (WST),standardized swallowing assessment (SSA) and modified Barthel index (MBI) were measured before treatment,after treatment and at follow-up visit (2 months after treatment).Results:After treatment,scores of WST and MBI in all three groups increased significantly (all P＜0.05),while the SSA score dropped significantly (all P＜0.05).After treatment and during follow-up visit period,score of WST in group C was significantly higher than that in group A and group B (both P＜0.05),while the difference between group A and group B showed no statistical significance (P＞0.05);the SSA score in group C was substantially lower than that in group A and group B (all P＜0.05),the difference between group A and group B showed no statistical significance (P＞0.05);the MBI scores in group B and group C were substantially higher than that in group A (all P＜0.05),the difference between group B and group C showed no statistical significance (P＞0.05).After treatment and during follow-up visit period,the differences in overall therapeutic effect between group A and group B showed no statistical significance (P＞0.05),while the overall therapeutic effect in group C was substantially better than that in group A and group B (all P＜0.05).Conclusion:Both mind-refreshing and orifice-opening needling method and swallowing disorder therapeutic apparatus can alleviate symptoms of deglutition disorder of stroke patients respectively,and the combination of two methods can improve the therapeutic effect.

In order to investigate the mechanism, the correlation between the odor change in Crataegi Fructus stir-fried process and 5-HMF were studied. Required samples were retrieved from Crataegi Fructus stir-fried process. Statistical quality control (SQC) was used to analyze the response values acquired by the electronic nose. At the same time, the content of 5-HMF was detected by high performance liquid chromatography (HPLC). Correlation analysis was used to analyze the relationship between the above two. Experimental results showed that SQC model established by response values of all samples could show the change law of odor in Crataegi Fructus stir-fried process and changes of 5-HMF content was dropped after the first increase. Correlation analysis showed that the odor change in Crataegi Fructus stir-fried process and 5-HMF were significantly correlated (P < 0.05). Sugar degradation reaction and the Maillard reaction may be one of the mechanisms of the odor change in Crataegi Fructus stir-fried process.

To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.

Objective The purpose of this work was to compare the efficacy of narrow band imaging-assisted transurethral resection of bladder tumour (TURB) with conventional white light imagingassisted TURB in primary non-muscle-invasive bladder cancer.Methods Several databases were searched,including Cochrance Libarary,PubMed,Embase,Wanfang,VIP,CNKI and CBM.The endpoints were biochemical failure in 3 months,1 year and 2 years.We performed a meta-analysis of the published data.The results are expressed as risk ratio (RR),with the corresponding 95％ confidence interval (CI).Results The final analysis included seven trials comprising 1889 patients.Biochemical failure in 3months (RR0.73,95％ CI 0.55-0.96;P =0.02),1 year(RR 0.69,95％ CI 0.58-0.80;P ＜ 0.01) and 2 years (RR 0.58,95％ CI 0.41-0.82;P =0.002) were fewer in patients who received narrow band imagingassisted TURB.The recurrence rates of 3 months,1 year and 2 years were 14.44％,29.35％ and 30％ in white light imaging group.The recurrence rates of 3 months,1 year and 2 years were 3.61％,9.35％ and 12.59％ lower in narrow band imaging group compared with white light imaging group.Conclusions Narrow band imaging-assisted TURB was superior to conventional white light imaging-assisted TURB in primary non-muscle-invasive bladder cancer in 2 years.

This study was aimed to distinguish Leonurus japonicus samples produced from different regions and growth environments in Sichuan by electronic nose. The sensor response value of odors of Leonurus japonicus sam-ples were obtained through electronic nose. Principal component analysis (PCA) and discriminant factor analysis (DFA) were used to combine the optimum feature parameters. The results showed that the PCA distinguish index was 82, and the DFA comprehensive classification rate was 97.96% among samples from different regions. The PCA distin-guish index was 84, and the DFA comprehensive classification rate was 100% among samples from different growth environments. The distinguishment and differentiation were effective. It was concluded that electronic nose can be ap-plied to identify the origin and growth environment of Leonurus japonicus from Sichuan to provided reference for odor differentiation.

Objective To study the efficacy,late complications and prognostic factors of postopera-tive radiotherapy for bladder cancer: Methods Between July 1995 and January 21307,109 patients with primary bladder cancer who had received adjuvant pelvic radiation therapy were retrospectively analyzed. The age ranged from 41 to 94 (median 68) years. There were 29 patients with T1 disease,60 with T2,17 with T3, 3 with T4, and 7 with positive lymph node. Three-dimensional radiotherapy was given with a median total dose of 49.2 Gy(39.3 -62.2 Gy) in conventional fractionation after surgery. Field-in-field intensity modu-lated radiotherapy was given to 57 patients. Results The total follow-up rate was 98% ,with a median fol-low up time of 36(2-144) months. The 1-,3- and 5-year local control rate was 63% ,47% and 42% ,respec-tively. The 1-,3- and 5-year overall survival rate was 80% ,48% and 37% ,respectively. Among the 109 pa-tients,33 died of tumor progression or metastasis,42 showed local recurrence,and 22 had lymph node metas-tasis. According to the RTOG criteria,grade 1,2,3 and 4 radiation related early urological side effects were 22% ,59% ,12% and 1% ,respectively;The corresponding late urological side effects were 29% ,28% ,2% and 1%, respectively. Two patients underwent whole bladder cystectomy due to the radiation related side effects. Conclusions Postoperative three-dimensional radiotherapy, achieving high response rate with tol-erable side effects, can be offered as an alternative option to the radical cystectomy in the bladder conserving treatment.
