OBJECTIVETo compare the differences of clinical effects on primary hypertension between acupuncture combined with auricular point sticking and western medicine.

METHODSNinety patients with primary hypertension were randomly divided into a medication group and a combination group, 45 cases in each group. In the medication group, captopril tablets were treated with oral administration, 12.5 mg each time, twice a day; in the combination group, acupuncture and auricular point sticking were used, and acupuncture was applied at Renying (ST 9), Fengchi (GB 20) and Baihui (GV 20), while auricular point sticking was adopted at Shenmen (TF4), Xin (CO15), Jiangyagou and Jiaogan (AH6a), once a day for continuous 4 weeks. After treatment, the changes of 24 h ambulatory blood pressure, angiotensin II (Ang II) level, creatinine level and syndrome scores were observed and the clinical efficacy was assessed in the two groups.

RESULTSAfter 4 weeks' treatment, the 24 h ambulatory blood pressure was both improved compared with that before treatment in the two groups (P<0.01, P<0.05). The reducing of 24 h ambulatory blood pressure in the combination group was superior to that in the medication group (P<0.05). There were reducing tendencies about coefficients of variation (CVs) of the two groups, and in the combination group, the CVs of 24 h ambulatory blood pressure and systolic pressure acquired more obvious reducing range compared with the medication group (both P<0.05). Serum Ang II level and plasma creatinine level of the patients in the two groups after treatment were both decreased (both P<0.05) and the reducing of Ang II level and creatinine level of the combination group was more obvious than that of the medication group (both P<0.05). The syndrome scores of the two groups after treatment were both remarkably decreased (both P<0.05), and the reducing of the syndrome scores of the combination group was more marked than that of the medication group (P<0.05). The total effective rate of the combination group was 95.6% (43/45), which was superior to 71.1% (32/45) of the medication group (P<0.05).

CONCLUSIONAcupuncture combined with auricular point sticking for primary hypertension has reliable effect. It is better than captopril for the improvement of 24 h ambulatory blood pressure, AngII level and creatinine level, and can improve dizzy, palpitation and other clinical symptoms.

Objective To investigate the effect of arsenic(As2O3) on spermatogenic cell apoptosis and the expression of telomerase activity in adult rats.Methods 40 healthy male Sprague-Dawle rats were randomly divided into four groups and they were treated with As2O3 at doses of 0(control group),0.375,0.75 and 1.5 mg/kg body weight respectively through gavage for 16 consecutive weeks.The numbers of testicular sperm head were counted and the coefficient of testicular viscera,daily sperm production(DSP) were calculated in every group.The apoptosis of germ cell was assessed by in situ terminal deoxynucleotityl transferase mediated dTUP nick end labeling(TUNEL) technique.The activity of telomerase in the spermatogenic cells was determined by immunohistochemistry.Results In the testes of As2O3-treated rats,the coefficient of testicular viscera,the number of testicular sperm head and DSP in moderate and high dose groups decreased significantly than that of control(P

Objective A survey was conducted to learn the status of award winning for science and technology achievement among the medical institutions ranked level 2 and above in Sichuan province,to learn the research capacity in such medical institutions,and to provide the basis for research management and health decision.Methods Questionnaire survey was carried out among 555 hospitals ranked level 2 and above in Sichuan province,information on award winning for science and technology achievement during 2010 -2012 was collected and analyzed.Results Only 33％ of those medical institutions were awarded for their achievement in research with total number of 882 awards in three years:300,266,and 316 awards were obtained in 2010,2011 and 2012,respectively.Conclusions In the medical organization of Sichuan province,the number of awards of scientific and technological achievements showed no significant increase with an volatility state,and the overall level of award need to be improved.Awarded Research areas were mainly on clinical research-based,especially on surgery department.Most award winning hospitals are level 3,and the general hospitals win more award than specialized hospitals;furthermore,hospitals located in different regions are quite different in terms of award winning.

Leveraging the centralized drug purchase platform of medical institutions in Beijing, the study measured the drug price index (DPI) and the DDD price index from 2005 to 2013, and the outcomes indicate a drop of both the drug price index and the drug price index calculated by DDD.Despite such drops however, drug price drop by itself could not curb the constant rise of drug expenses and medical costs due to changes in the structure and interval of drug administration.

In order to investigate the impairment of mitochondrial membrane phospholipid localization and DNA(3867) (mtDNA(3867)) deletion and the correlation between cardiac and skeletal muscle cells in mice with viral myocarditis, 50 BALB/c mice were divided into two groups randomly. In experimental group (n=40), the mice were intraperitoneally injected with 0.1 mL Eagle liquid with CVB3(TCID50=10(8)), while in the control group (n=10), the mice were subjected to equal volume of Eagle liquid. The impairment of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion rate of cardiac and skeletal muscle were detected separately at day 3, 11 and 24 after injection. The correlation of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion rate between cardiac and skeletal muscle cells cells was analyzed using Spearman method. At the day 3 after injection, in both cardiac and skeletal muscle cells, mtDNA(3867) deletion rate was significantly higher in experimental group than in control group (P<0.05), but the localization of mitochondrial membrane phospholipid showed no difference between two groups (P>0.05). At day 11 after injection, the mtDNA(3867) deletion rate of both cells in experimental group was increased to the peak level (P<0.05), and the impairment of mitochondrial membrane phospholipid localization of both cells also increased markedly in experimental group as compared with control group (P>0.05). At the day 24 after injection, the impairment of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion of both cells showed a recovery tendency, but still severer than those at the day 3 after injection (P<0.05). The impairment of mitochondrial membrane phospholipid localization and mtDNA(3867) deletion were consistent and synchronistic between cardiac and skeletal muscle cells, and showed good correlations (P<0.05). The impairment of mitochondria plays an important role in the pathogenesis of viral myocarditis, and the skeletal muscle cells might act as a peripheral "window" to reflect the mitochondrial damage of cardiac myocytes.

Gene deletion vector pLJ04(pKC1139∷bkdF+bkdH)was used to disrupt bkdFGH in Streptomyces avermitilis 76-02-e,an industrial producer of anthelmintic avermectin.The disruptants were confirmed by PCR.Shake flask experiment and HPLC analysis showed that the mutant lost the ability to produce avermectins.As it is expected,the mutant,named S.avermitilis bkd76-3,could restore the ability of producing avermectins when the feeding of methylbutyric acid and isobutyric acid to its fermentations was carried out.The addition of cyclohexanecarboxylic acid(CHC)into fermentations of the S.avermitilis bkd76-3 allowed for production of four components,two of which was confirmed as CHC-B1 and CHC-A2 by LC/MS analysis,respectively.

Objective To explore the value of DWI combined with dynamic contrast-enhanced MR imaging (DCE MRI) in differential diagnosis of benign and malignant parotid gland tumors.Methods DWI and DCE-MRI was performed in 90 patients with parotid gland tumors (94 lesions),included 75 benign tumors and 19 malignant tumors.The ADCs were measured,and the type of time-intensity curve (TIC) was assessed.ROC curve was used to analyze the diagnostic efficacy of ADC values,TIC types and combination of the two methods in diagnosing benign and malignant tumors.Results The ADC values of malignant tumors ([1.02 ± 0.25] × 10a mm2/s) were significantly smaller than that of benign tumors ([1.38±0.44] × 10-3 mm2/s;t=5.170,P＜0.001).The sensitivity was 0.62 and specificity was 0.92,when type A (persistent),B (washout),and D (flat) tumors regarded as benign and type C (plateau) tumors regarded as malignant.Sensitivity and specificity were significantly improved in diagnosis of malignant tumors when combined type C and ADC＜1.36× 10-3mm2/s,which were 0.92 and 0.95,respectively.Conclusion Due to an overlap within benign and malignant parotid tumors,the diagnosis should not be addressed on the basis of ADC values alone.The TIC manifestations type A,B or D on DCE-MRI indicates benign parotid tumors,and type C indicates malignant diseases.When the TIC shows type C,combining ADC value can elevate the differential diagnostic efficacy of benign and malignant parotid tumors.

This study is to investigate the effects of concentration, intestinal section, pH, paracellular route, substrate/inhibitor of enzyme (CYP3A) and proteins (P-gp, MRP2, SGL1) on the absorption of forsythoside A. The absorption of three concentrations (2.6, 5.2, and 10.4 microg x mL(-1)) of forsythoside A in different intestinal segments was studied with phenol red as the marker by rat circulation in situ. The results showed that the residue of forsythoside A with different concentrations had little significant difference from that obtained after perfusing via duodenum, jejunum, ileum and colon, which indicated that the absorption of forsythoside A was passive diffusion and had no difference in different segments of rat intestine. The residue of forsythoside A increased to 466.160 and 463.429 microg respectively when cyclosporine (4 microg x mL(-1)) or midazolam (50 micromol x L(-1)) was added to the circulation fluid, which showed significant difference compared to the control group (P < 0.05). Moreover, the residue of forsythoside A showed a tendency of increase with the increase of cyclosporine or midazolam. When digoxin (50 micromol x L(-1)) or EDTA (10 microg x mL(-1)) was added to the circulation fluid, the residue of forsythoside A decreased to 325.110 and 369.888 microg respectively, which showed significant difference as compared to the control group (P < 0.05). Besides, the residue of forsythoside A showed a tendency of reduction with the increase of digoxin or EDTA. However, there is no significant change in the absorption of forsythoside A when the different concentrations of mannitol were added to the circulation fluid. The results above indicated that the absorption of forsythoside A was mainly passive diffusion and involved paracellular route at the same time. In addition, the substrates of P-gp or CYP3A had dose-dependent effect on the absorption of forsythoside A.
