This paper reviewed the policies on private medical institutions in Henan province since the new healthcare reform.Combined with relevant statistical data,the authors found that conceptual obstacles,policy implementation,lack of unified management and restriction of human resource flow as important constraints of the development of such institutions in the province.In view of this finding,the authors made in-depth study of the development positioning,general role of planning and market functions,as well as support and regulation in parallel of such institutions,in order to promote the healthy and sustainable development of private medical institutions in China.

Objective To observe the efficacy of Huoxue Tongmai decoction in the treatment of coronary heart disease with angina pectoris.Methods 60 coronary heart disease patients with angina pectoris were randomly divided into two groups,30 cases in each group.The observation group was treated with Huoxue Tongmai decoction concomitant with routine chemical medicine therapy,and the control group was treated with only routine chemical medicine therapy.The total effective rate,reduced angina occurrences after therapy and ECG were observed in both two groups.Results After treatment,the total effective rate of the observation group was 93.3%,which was signifi-cantly higher than that of the control group(χ2 =4.32,P <0.05).Compared with the two groups of ECG efficacy,the total effective rate of the observation group was 83.3%,which was significantly higher than 66.7% of the control group (χ2 =4.22,P <0.05).After one,three treatment courses,the number of angina attack in the observation group was significantly lower than that in the control group,and the differences were statistically significant(t =6.99, 10.82,all P <0.05).Conclusion Houxue Tongmai decoction combined with routine chemistry medicine is more effective than routine chemistry medicine in treating angina.

Drug-induced nephrotoxicity is very common in both new drug development and clinic practice. Various drugs can induce kidney injuries, including tubulointerstitial, glomerular and renal vascular disease. To investigate the mechanism of drug induced nephrotoxicity is important for risk reduction of new drug development, reasonable drug usage, early discovery and effective prevention/treatment of adverse effects in clinics.

Objective To investigate the effect of valsartan and amlodipine on urinary microalbumin in elderly hypertensive patients. Methods 100 elderly patients with hypertension treated in our hospital from May 2015 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group received oral valsartan, and the patients in the experimental group were treated with valsartan and amlodipine. The treatment time of the experimental group and the control group was 12 weeks. The clinical indexes of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the experimental group and the control group did not have obvious adverse reactions. There were 2 cases of headache in the experimental group, 1 cases of vertigo, and 2 cases of vertigo in the control group. However, there was no significant difference in the incidence of adverse reactions between the experimental group and the control group, and there was no statistical significance. The antihypertensive effect of the experimental group was significantly higher than that of the control group, with statistical significance (P<0.05). After treatment, the urinary microalbumin in the experimental group and the control group was significantly lower than that in the treatment group, and the level of microalbuminuria in the experimental group was lower than that in the control group, with statistical significance (P<0.05). Conclusion The clinical effect of treatment of elderly patients with hypertension better combined with valsartan and amlodipine, antihypertensive effect is stronger, can significantly improve the patient's urinary albumin, with further clinical promotion and application significance.

Objective: To analyze the polymorphism in human cDNA sequence of prothymosin α (ProTα) by sequencing analysis. Methods: The cDNA of human ProTα was amplified from cells of peripheral blood and cord blood by RT-PCR. The product of RT-PCR was purified and linked with vector pMD18-T. After cloning and sequencing, the sequence of ProTα cDNA was compared with the standard sequence to analyze the polymorphism in the ProTα cDNA sequence. Results: The cloned ProTα cDNA sequence was different from that of the standard. We found 2 kinds of variations: (1) The nucleotide in 107 position was varied and the nucleotides in 110-121 and 191-205 positions were deleted; (2) The nucleotide in 306 position was deleted, mainly in the 60-80 years old group. Conclusion: We have identified 2 kinds of variations in human ProTα cDNA, but the first 28 amino acid in the N-terminal of cDNA of human ProTα are not involved therefore the variations do not affect the function of human ProTα.

Objective: To study the expression of chemokine receptor CCR5 in follicular thyroid carcinoma and the serum level of CCR5 ligand, so as to assess the role of CCR5 in progression and metastasis of follicular thyroid carcinoma. Methods: Fifteen samples of follicular thyroid carcinoma, 17 samples of follicular thyroid adenoma and 12 adjacent normal samples were analyzed immunohistochemically for CCR5 expression. The sera concentrations of CCL3, CCL4 and CCL5 were measured by ELISA in all patients. Results: CCR5 was positive in follicular thyroid carcinoma samples, with the positive rate being 73.33%, and was not detected in the follicular thyroid adenoma and the normal samples (P<0.01). The concentrations of CCL3 and CCL5 in the sera of follicular thyroid carcinoma patients were significantly higher than those of the other 2 groups (P<0.05). Conclusion: CCR5 is highly expressed in follicular thyroid carcinoma tissues and the concentrations of CCL3 and CCL5 are obviously increased in the sera of patients, indicating that CCR5 may play an important role in the pathogenesis of follicular thyroid carcinoma.

Abstract Objective:To explore antitumor effect of NDV HN. Methods: pIRHN nucleic acid vaccin was constructed and was transfectedto Hela cells. Westem blot was used to analyssize the expression of pIRHN nucleic acid vaccine in eukarytic cell. The mode of cell death was de-tected by fluorescence microscope, gel electrophoresis and TUNEL assay. The effect of pIRHN nucleic acid vaccine on the contents of siaha acidin the Hela cell was examined.
