Select patients diagnosed of hypertension in the first place in 16 hospitals and the patients were described by association rules analysis and distribution for the analysis in the study,in order to understand the information of diagnosis and treatment in hypertension patients in real world. The information include age, gender, admission condition, inpatient department, hospitalization expenses, western medicine comorbidities, the traditional Chinese medicine (TCM) syndrome and the medicine. The average age of patients was 64 years in the study. The proportion of men to women about 1. 10: 1. Admission condition is critical for about 10.12% of the total and more concentrated in the cardiovascular department. Hospital stay ranged from 8 to 14 d. Inpatients with medical insurance is 62.93%. Total hospitalization cost distribution most is the 5 000-10 000 RMB. Hypertension complicated with coronary heart disease, blood lipoprotein disorder disease; phlegm and blood stasis and Yin deficiency of liver and kidney are the most in TCM syndrome type. Promoting blood circulation and removing blood stasis is the major in Chinese medicine treatment. Western medicine treatment basically conforms to the guidelines. The most antihypertensive drugs is calcium antagonistst, accounting for about 81.2% of the total number. Class ACEI, class ARB, beta blockers, diuretics class are accounted for 43.0%, 43.4%, 42.4%, 42.4%, fixed compound is only 2 393, accounting for about 8%. the total frequency of five classes of antihypertensive drugs is 78 206 times. The principal conclusions of this analysis are as follows: the elderly people is the most in hypertension, more men than women; medical insurance is the majority type in hospitalization cost; nearly half of the population is combined with coronary heart disease; phlegm and blood stasis and yin deficiency of liver and kidney are the most in TCM syndrome type; western medicine treatment basically conforms to the guidelines. Combination therapy is more, less fixed compound preparation in western medicine. Chinese medicine is mainly to promoting blood circulation. Suggesting that the clinical treatment in strict blood pressure and at the same time, pay attention to combination therapy and the use of fixed compound preparation,it's useful to control the blood pressure better. Combined with traditional Chinese medicine and resolving phlegm and removing blood stasis, reduce the target organ damage, reduce complications, the prevention and control work of hypertension in China still faces enormous challenges at present. The result provides reference information for clinical medicine and medical research.

Objective To investigate the effect of up-regulating miR-34c-5p on cloning formation and migration of nasopharyngeal carcinoma cell line HONE-1 in vitro. Methods Expression levels of miR-34c-5p in nasopharyngeal cell line NP69 and nasopharyngeal carcinoma cell line HONE-1 were investigated by real time quantitative PCR;Cloning Forma?tion Test and Transwell Migration Assay were used to explore the effect of up-regulating miR-34c-5p on proliferation and migration of nasopharyngeal carcinoma cell line HONE-1. Results The expression of miR-34c-5p in nasopharyngeal car?cinoma cell line HONE-1 was lower than that in normal nasopharyngeal cell line NP69. Up-regulating miR-34c-5p signifi?cantly suppressed the cloning formation and migration capacity, compared to those of NP69 cell line and HONE-1 with nor?mal level of miR-34c-5p(P<0.05). Conclusion Down-regulating miR-34c-5p involve in proliferation and migration of nasopharyngeal carcinoma and may be a used as a new therapeutic target for nasopharyngeal carcinoma.

OBJECTIVETo establish a new method for determining norepinephrine (NE) in the presence of epinephrine and ascorbic acid using proline-modified glassy carbon electrode (GCE).

METHODSIn phosphate buffer solution (pH 9.0), the poly-proline-modified electrode was prepared by cyclic voltammetry method. The voltammetric behavior of NE on poly(proline) film were analyzed to establish a electrochemical analysis method for determination of NE on the modified electrode.

RESULTSIn PBS (pH 7.0), a couple of redox peaks of NE was observed on the modified electrode. The modified electrode was used to determine NE in a excess of epinephrine (EP) and ascorbic acid (AA) by reduction peak current of cyclic voltammetry. The reduction peak currents were in linear relationship with the NE concentrations within the range of 7.0 x 10(-7) to 1.1 x 10(-4) mol/L, with the detection limit of 6.0x10(-8) mol/L.

CONCLUSIONThe modified electrode shows good sensitivity, selectivity, and stability for NE determination, and is well applicable for analysis of injection solution samples.

Heat shock protein 27 ( HSP27 ) is an endogenous protein that plays an important role in a great variety of physio-logical and pathological processes. It can express a large number under body stress conditions. Recent studies have shown estro-gen upregulates the expression of HSP27 through a number of ways, playing a perfect “triple protection” role. In the early stage of atherosclerosis, estrogen induces the phosphorylation of HSP27 via PI3K/Akt signaling pathway. Phosphorylation of HSP27 can resist the injury of vascular endothelial cells( VECs) through an antioxidant and anti-apoptotic pathway as well as the inhibition of cytochrome C. In the stage of forming foam cells, estrogen induces the expression and release of HSP27 from mac-rophages by stimulating the estrogen receptor β ( ERβ) , then HSP27 inhibits the LDL uptake and the release of proinflammato-ry cytokine by binding scavenger receptor A ( SR-A) . During the proliferation and migration of vascular smooth muscle cells ( VSMCs) , estrogen induces estrogen receptor α ( ERα) and protein phosphatase 2 ( PP2A) to form a complex that enhances the activity of PP2A, then it can lead to the dephosphorylation of HSP27 and finally inhibit cells proliferation and migration. In summary, the anti-atherosclerotic effect of estrogen is closely re-lated to the role of HSP27. Given the side effects of estrogen re-placement therapy( MHT) , regulating HSP27 may provide a no-vel therapy for the prevention and treatment of cardiovascular dis-eases in menopausal women clinically.

Objective: To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6-9 years old.Methods: A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method, with 95 cases in each group. The observation group was intervened by auricular point sticking plus guide on a healthy diet, while the control group was only provided with the guide on a healthy diet. The therapeutic efficacy was observed after intervention for three consecutive months, as well as the changes in body mass (BM), body mass index (BMI), waist circumference (WC), hip circumference (HC), and subcutaneous fat thickness. Results: After the 3-month intervention, the total effective rate was 91.6％ in the observation group, versus 74.7％ in the control group, and the between-group difference was statistically significant (P<0.01); in both groups, the BM, BMI, WC, HC, and subcutaneous fat thickness all decreased significantly (P<0.05), and were lower in the observation group than in the control group, showing statistical significance (P<0.05). Conclusion: Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children, producing more significant efficacy than healthy diet intervention alone.

The study aims to establish a method for simultaneous determination of repaglinide and pravastatin sodium in rat plasma by LC-MS/MS and to study its pharmacokinetic interactions. Eighteen male SD rats were divided into repaglinide group, pravastatin sodium group and co-administration group. Blood samples were collected at different times after oral administration. Repaglinide and pravastatin sodium in rat plasma were separated by Agilent HC-C18 with the mobile phase consisting of methanol-0.1% formic acid (80 : 20). Detection and quantification were performed by using ESI-MS. The detector was operated in selected Reaction-monitoring mode at m/z 453.3-->230.1 for repaglinide, m/z 447.2-->327.4 for pravastatin sodium and m/z 285.1-->192.9 for diazepam as the internal standard. The calibration curve obtained was linear (R2>0.99) over the concentration range of 9.77-10,000 ng.mL-1 for repaglinide and 4.88-625 ng.mL-1 for pravastatin sodium. Compared with the single administration group, Cmax and AUC0-6h of repaglinide increased significantly (P<0.05) and tmax of pravastatin sodium prolonged (P<0.05) in co-administration group. The method is found to be simple, sensitive and accurate for determining the concentration of repaglinide and pravastatin sodium in rat plasma. There exists pharmacokinetic interactions in the co-administration of repaglinide and pravastatin sodium.

OBJECTIVETo evaluate the prognostic effects of neoadjuvant chemotherapy (NAC) in patients with local advanced gastric cancer.

METHODSWe retrospectively analyzed prognosis in 191 patients with advanced gastric cancer, of whom 71 were treated with NAC and 120 received surgery only between February 2007 and July 2013. Postoperative complication rate was recorded. Survival by clinicopathological features, pathological T and N stages, and histopathological tumor regression was retrospectively compared between the two groups.

RESULTSAccording to Response Evaluation Criteria in Solid Tumors, none of the 71 patients in the NAC followed by surgery group showed complete response, 36 showed partial response, 25 had stable disease, and 10 had progressive disease. The chemotherapy response rate was 50.7%; the disease control rate was 85.9%. Grade 3/4 adverse events were seen in less than 20% patients, with acceptable toxicities. No difference was found in the overall postoperative complication rates between the two groups (7 versus 22 cases, P=0.18). Median survival time was significantly different, at 54 months in the NAC combined with surgery group and 25 months in the surgery-only group (P=0.025).

CONCLUSIONIn patients with operable gastric adenocarcinomas, NAC can significantly improve overall survival without increasing surgical complications.
