Caspases are a group of enzymes mainly for the execution of apoptosis.In recent years,studies have shown that caspases participate in the occurrence and development of many diseases,especially tumors and nervous system diseases.Of those,caspase-9 is one of the most important initiating molecules.This article reviews the structural characteristics,activation and regulation of caspase-9,its regulation mechanism of apoptosis,and briefly describes its relation with ischemic cerebrovascular disease.

Extracellular high mobility group box 1 (HMGB1) can cause persistent inflammation via related receptors and signal pathways such as receptor for advanced glycation endproduct,Toll-like receptors and chemokines 12,which results in tumorigenesis.In patients with cervical cancer,the expression of HMGB1 increases with the rising of malignant gTade.HMGB1 participates in the genesis and development,invasion and metastasis of cancer through multiple processes.The expression of HMGB1 is inhibited by RNA interference,thus affects the invasion and migration of cervical cancer cell,which provides a new concept for the development of antineoplastic agents.

OBJECTIVE:To discuss the characteristics and regularity of drug-induced deaths so as to promote the ra?tional use of drugs in the clinic.METHODS:The case reports on drug-induced deaths retrieved from Chinese medical science periodicals from1998to2004collected in CHKD periodicals knowledge base in China hospital digital library were analyzed statistically.RESULTS:Of the total drug-induced deaths,43.85%were by iv,which dominate the first place in terms of fatality rates;antimicrobials,Chinese herbal medicine,antineoplastic agent and drugs that affect blood system and hematopoietic system dominated the first5places in terms of the fatality rates;the mortality of allergic shock was higher,which made up about31.81%.CONCLUSION:An indispensable measure to reduce drug-induced disease and its fatality rate is to strictly control the indications of medication and enhance the cultivation of professional staffs'professional activities and service quali?ty.

Objective To investigate the effects of levofloxacin on serum interlukin 6(IL-6) and interferon γ(IFN-γ) levels in the treatment of elderly patients with pulmonary tuberculosis.Methods A total of 87 senile pulmonary tuberculosis patients were collected and randomly divided into experiment group and control group.43 patients in the control group were given standardized treatment, 44 patients in the experiment group were treated on the basis of the control group were given levofloxacin, the total treatment was 6 months.By comparing serum IL-6 and IFN-γlevels changes of the patients before and after treatment and negative conversion ratio after treatment and degree of lesions changes of the two groups ,the effects of levofloxacin on pulmonary tuberculosis were explored.Results Compared with before treatment in the two groups, serum IL-6, IFN-gamma levels were significantly lower after treatment, the above indexes in experiment group were higher than those in control group (P<0.05).After 6 months treatment, negative conversion ratio in sputum bacteria in control group was 30 cases (69.77%), and 40 cases (90.91%)in experiment group, with significant difference ( P<0.05).Of the control group, the significant absorption, absorption and deterioration was respectively 22 cases (51.16%), 8 cases (18.60%), 13 cases (27.90%),of the experiment group was 31 cases (70.45%), 9 cases (20.45%), 4 cases (9.09%),respectively.The total lesions absorption rate of the experiment group (90.91%) was significantly higher than control group (69.77%) (P<0.05).Conclusion Levofloxacin in the treatment of senile patients with pulmonary tuberculosis can reduce serum IL-6 and IFN-γlevels, improve the patients'negative conversion ratio of sputum bacteria and total lesions absorption rate, has a good effect for the treatment.

al recovery. Therefore, EPC may have broad application prospects in the field of ischemic cerebrovascular disease.

The previous studies identify connexin as a tumor suppressor gene,which inhibits the occurrence and development of breast cancer.However,some researches of resent years demonstrate that the expression level of connexin in a large part of metastatic breast cancer is elevated and connexin may promote breast cancer metastasis.Therefore,connexin may play different roles by different mechanisms in the occurrence,development,invasion and metastasis of breast cancer.Rational use of connexin in breast cancer treatment can be beneficial to breast cancer patients.

Ample evidences have showed that the failure of early regeneration of the central nervous system(CNS) in adult mammals is mainly due to the growth inhibitory factor. Efforts have been made to promote neuron regeneration and neurological function recovery by damaging myelin and removing myelin-associated inhibitors. At present, the Nogo protein associated drugs and gene therapy have become a novel effective way to promote axon regeneration after CNS injury; here we reviews the recent progress on the related issues.

Objective:To analyze essential health care equity in cities and counties of Hainan in order to provide the basis for its development. Methods:Based on health statistics of Hainan, China and OECD countries, indicators of essential health care equity in cities and counties were analyzed. Results:Equity in distribution of resources, the hospi-tal geographical distance is large difference, physician-to-nurse ratio is 1:1. 2, and the Gini coefficient is more than 0. 3. Equity in financing, health care spending per capita is less than the national level. Cities and counties with high government budgets for health are located in regional centers. The hospitalization costs compensation with new rural co-operative medical scheme is about 50%. Equity in service supply, bed occupancy rate below 90% and drugs accounted for 30% ~40% in most cities and counties. Regional differences in maternal and child health management are small, but below the national level. Conclusions:The situation of essential health care resources is related to the political and economic climate. Financing mechanisms for essential health care are imperfect;and a low supply of basic medical and public health services reduced the quality of essential health care. Suggestions:Rational distribution of essential health care resources should be promoted;essential health care financing should be increased;and the capability of essential health care supply should be improved.

Objective To evaluate the the brow position and shape in young Chinese women using a photography measurement.Methods A total of 100 Chinese women aged 20 to 30 years were photographed to determine the distance between brow and eye.Measurements were made from a horizontal plane through the lateral canthus of right eye to three vertical points on the upper brow margin at the medial canthus,lateral limbus of the iris,and lateral canthus.Results The distance between brow and eye in young Chinese women was 2.12,2.52 and 2.46 cm at medial canthus,lateral limbus of the iris and lateral canthus,respectively.The distances were higher between the brows and eyes at lateral limbus of the iris and lateral canthus than that at medial canthus (P＜0.05).Conclusions The measurement used in this study is a simple and practical quantitative method.The results can be used to guide the surgical choice and help to evaluate the surgical techniques.
