Objective To investigate the effects of Benazepril on inflammatory cytokines in patients with primary hypertension and its efficacy analysis.Methods 72 patients with mild to moderate primary hypertension were randomly divided into benazepril group(37 cases)and control group(35 cases).The control group patients were given felodipine sustained release tablets Stag,1 times daily.Benazepril group were given benazepril tablets 10mg,1 times daily.Both groups were treated for 8 weeks.Changes in blood pressure and heart rate,plasma inflammatory cytokine levels and the adverse reactions were observed.Results After 8 weeks of treatment,the patients' blood pressures were significantly decreased (t =2.87,2.43,2.31,2.23,P ＜ 0.05 or P ＜ 0.01) than before in both groups.And the decrease in the benazepril group was more obvious than that in the control group (t =2.21,2.13,all P ＜ 0.05),while the patients' heart rates in the two groups showed no significant change (P ＞ 0.05) ; Patients' plasma IL-4 and IL-8 levels decreased significantly,plasma IL-10 levels increased significantly (t =2.99,2.87,3.21,2.13,2.19,2.23,all P＜0.05 or P＜0.01),and the magnitude of decrease or increase in the benazepril group were more obvious compared with the control group (t =2.21,2.13,2.34,all P ＜ 0.05).Conclusion Benazepril in the treatment of primary hypertension has good antihypertensive effect and security which can significantly reduce the plasma levels of proinflammatory cytokines IL-4 and IL-8 levels,improve the anti-inflammatory cytokine IL-10 levels,and has the role of suppressing the inflammatory response of the vessel wall.

Objective:To study the antimicrobial susceptibility of periodontopathic bacteria associated with failing implants to commonly used antibiotics in periodontal therapy and dental practice.Methods:Antimicrobial susceptibility of bateria isolates was determined by the method of microbroth dilution and the activities of 8 kinds of antibiotics against international laboratory strains and clinical isolates of Provotella intermedia (Pro.I), Porphyromonas gingivalis (Pg), Actinobacillus actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn) were examined.Results:Ofloxacin, clindamycin, tinidazole and metronidazole showed stronger antibacterial activity aginst Pro.I,Pg,Aa and Fn with MIC_ 90 ≤0.5 ?g/ml and MBC_ 90 ≤0.5 ?g/ml.Conclusion:Commonly-used antibiotics are potential against bacteria isolated around failing implants.

In view of the current conditions and reasons about the reform of medical and health system in China,the paper expounds the feasibility of authorized operation with state-owned assets of public hospital and the concrete operational pattern from the angle of hospital operational mechanism, which proposes a new idea about how to effectively solve the contradiction between the limited investment on state-owned health resources and the growing demands on medical health.

Objective To study the main causes of hearing disability in Beijing residents. Methods The second national sample survey on disability of China was carried out in Beijing on April 1,2006. Muhiphase, stratified, proportional and cluster samplings were adopted to investigate 74 795 residents in Beijing, including 36 753 males and 38 042 females. 55 773 were urban residents while 19 022 from rural areas. The method of descriptive study was used to analyze the data of hearing disabitity in Beijing. Results Top five causes of hearing disability (including multiple disabilities) in Beijing were presbycusis, unknown, systematic diseases, noise induced, and odds media. The prevalence was 1.10%, 0.30%, 0.30%, 0.20% and 0.17%, respectively. Heredity, unknown and others were the main causes of children under 0～14 years. Unknown, ototoxicity, and otitis media were the main causes of people aged 15 ～59 years. Presbycusis, systematic diseases, noise induced and unknown were main causes of people aged 60 years and older. Presbycusis was the top cause of hearing disability for male and female residents as well as people live in urban and rural areas in Beijing. Conclusion Presbyeusis, unknown, systematic diseases, noise induced, and otitis media were main causes of hearing disability (including multiple disabilities) in Beijing.

Gene therapy has emerged as an efficient modality to treat human diseases.This method is based on the transfer of genetic material to tissues to induce a curative effect.Gene therapy vectors are molecular constructs used to facilitate the penetration of genomic sequences inside the cells.Viral vectots have however several limitations when administered directly to the patient.They may cause significant toxicity by activating innate immunity or by eliciting an adaptive immune response against viral proteins.In addition,targeting the vector to the desired site is an issue when given systemically.The use of cells as vehicles for gene therapy vectors has many advantages.The combination of cell-viro-gene therapy has been thought as a new and promising strategy for therapy of cancer.The targeting vector to cancer stem cells will become a new direction in the field of gene therapy.In this article,we will introduce progressions,limitations and future directions of gene therapy of liver cancer.

The "Cancer Toxin" pathogenesis theory is an innovate theoretical system for cancer pathogenesis of Chinese Medicine, which was built on the basis of "Cancer Toxin" concept initially raised by Professor ZHOU Zhong-ying. The mechanism of the transformation from inflammation to carcinoma has become one of hot-points in the field of cancer research at home and abroad in recent years. We focused on discussing the relevance of the "Cancer Toxin" pathogenesis theory with the transformation mechanism from inflammation to cancer, provided evidence for using "Cancer Toxin" pathogenesis theory in intervening transformation from inflammation to cancer, hoping to guide for Chinese medical prevention and treatment of tumor.
