[Effects of Huoxue Qianyang Formula on expressions of proto-oncogenes c-fos and c-myc in spontaneous hypertensive rats with ventricular hypertrophy].

OBJECTIVE: To explore the possible mechanism of Huoxue Qianyang Formula (HXQYF), a compound traditional Chinese herbal medicine, in reversing the left ventricular hypertrophy (LVH) of spontaneous hypertensive rats (SHRs) by analyzing the expressions of mRNAs and proteins of proto-oncogenes c-fos and c-myc in left ventricular muscle. METHODS: The experimental study was carried out in SHRs, the sex- and age-matched Wistar-Kyoto (WKY) rats were served as normal control (n=5, normal saline 10 ml/kg daily). Twenty-five SHRs were randomly divided into five groups: untreated group (n=5, normal saline 10 ml/kg daily), high-dose HXQYF-treated group (n=5, 0.84 g/ml HXQYF, 10 ml/kg daily), medium-dose HXQYF-treated group (n=5, 0.42 g/ml HXQYF, 10 ml/kg daily), low-dose HXQYF-treated group (n=5, 0.21 g/ml HXQYF, 10 ml/kg daily) and cilazapril-treated group (n=5, 1 mg/ml cilazapril, 10 ml/kg daily). The drugs were intragastrically administered once daily for 14 weeks. The expressions of mRNAs and proteins of proto-oncogenes c-fos and c-myc in left ventricular muscle were detected separately by in situ hybridization histochemical method and immunohistochemical method. RESULTS: Compared with the normal control group, the expressions of mRNAs and proteins of proto-oncogenes c-fos and c-myc in left ventricular muscle were significantly increased in untreated group (P<0.01). After treatment, the expressions of c-fos and c-myc mRNAs in left ventricular muscle in HXQYF-treated groups were significantly down-regulated as compared with those of the untreated group (P<0.05). The expressions of c-myc protein were also significantly decreased in high- and medium-dose HXQYF-treated groups as compared with the untreated group (P<0.05), but it had no significant effects in protein expression of c-fos in the three HXQYF-treated groups. CONCLUSION: HXQYF can inhibit the expression of c-myc in ventricular hypertrophy tissue, which may be the mechanism in treating LVH of hypertension.

[Thinking on hospital construction of integrated traditional Chinese and Western medicine].

OBJECTIVE: Through supervising the construction of some key hospitals of integrated Chinese and Western medicine (ICWM), the characteristic indexes and problems concerning hospital construction were analyzed. It was pointed out that in order to improve the level of construction and administration of ICWM hospitals, the overall effect of construction should be paid attention to, the cultivation of ICWM professionals should be strengthened and the ICWM standard based assessment on clinical efficacy should be stressed. Besides, the strategies on administration pattern of ICWM hospitals were discussed.

Prospects of a comprehensive evaluation system for traditional Chinese medicine services.

Traditional Chinese medicine (TCM) is a unique health resource in China and one of the main representative traditional medicines globally. TCM has formed a new way of looking at medical practices, health care, scientific research, education, industry and culture. It focuses on promoting and safeguarding the health of people, with an increasing contribution to economic and social development. Establishing a comprehensive evaluation system in accordance with the characteristics of TCM services could promote the scientific merit and the standardization of services management. This would improve health service quality and the social and economic benefits of TCM. It would broaden the field of TCM services research. It would also provide the basis for the formulation of relevant government policies. This study estimates the prospect of establishing a comprehensive evaluation system of TCM services.
