Epidemiological studies indicated that dietary tiber was inversely associated with stroke risk.Epidemiological studies have confirmed that increased dietary fiber intake can reduce the risk of stroke.Animal experiments and clinical studies have shown that dietary fiber intake may reduce the incidence of stroke by reducing vascular risk factors,such as hypertension,diabetes,dyslipidemia,and obesity.The direct mechanism of increased dietary fiber intake reducing stroke risk remains to be further studied.Clinicians should pay attention to the important role of dietary fiber,guide the patients with stroke and individuals at risk of stroke to increase consumption of fiber-rich fruits and vegetables.

Aim To study whetger there is positive express in situ hybridization of L-form DNA or Staphylococcus aureus in laryngocarcinoma cell. Methods 20 cases of expressnon of L-form DNA of Staphylococcus aureus in laryngocarcinoma karyon were detected with nucleic acid in situ hybridization. Results 60% cancer karyon, cytoplasm display positive signal of Staphylococcus aureus L-form DNA. Positive rate of Staphylococcus aureus L-form antigen is 75% with immunohischemical (s-p) stainipg. The rate is 70% with gram staining. Conclusion Staphylococcus aureus L-form DNA had get into laryngocarcinoma ceells, is great possibly to integrate into host ce11, and influence hyperplasis and canceration of cell from gene level. Staphylococcus aureus and its L-form infection have possibly close relation to happen and development of laryngocarcinoma.

Objective:To summarize the development of the HIV/AIDS designated hospital system, analyze the main issues and explore solutions for this system. Methods:184 leaders/experts of three levels of healthcare facilities ( provinces, cities and counties) from 30 provinces engaged in AIDS prevention and control for over five years, and 2,432 people living with HIV/AIDS(PLWHA) from seven provinces were investigated through two different question-naires. Results:According to the staff responses, the issues of surgery and hospitalization are difficult and outstand-ing for PLWHA due to the current designated hospital system with scores of 6. 49 in severity. Of the ten largest prob-lems, ranked third is the need for improved AIDS prevention and control. 2 367 (97. 3%) PLWHAs had an aware-ness of the designated hospitals, 1,376 received treatment in the designated hospitals, and 85. 5% believed that the illness was effectively treated, while 9. 0% thought that the medical technology of the designated hospital was limited;18 . 7% of hospitalized HIV/AIDS patients or those who received surgery experienced prevarication by the non-des-ignated hospitals. Policy analysis shows that China’s designated hospital system for PLWHA has developed gradually with the characteristics of periodic and temporary changes. Conclusion:The designated hospital system for PLWHA in China has played an important role, but there are still several problems. The government should improve the existing system by strengthening the comprehensive medical service capacity of designated hospitals, improving the mechanism of consultation and referrals, coordinating the non-designated hospitals to provide technical support, reducing dis-crimination and fear from medical staff against HIV/AIDS, decreasing the risk of occupational exposure, and enhan-cing the communication among hospitals, CDCs and patients.

Objective To detect the PTEN gene mutation and loss of heterozygosity(LOH) on chromosome 10q in oligodendrogliomas. Methods The entire PTEN coding sequence of the 9 exons were screened by 9 different PCR reactions and followed by denaturing gradient gel electrophoresis(DGGE) and direct sequencing for detecte mutation.Microsatellite markers with fluorochrome on 10?q amplified by PCR were used to detecte LOH by PAGE on an automatic sequencer and analyzed with the Gene Scan program in 55 oligodendrogliomas and mixed oligodendrogliomas. Results The PTEN gene somatic mutations were detected in 2 tumors,one case that carried a PTEN mutation deletion T base in position 20 resulting stop codon moved to 347.Another case was a A to C transition at the codon 139 resulting in changeing from Leu to Phe.Twenty\|three of 55(42%) cases were observed the loss of heterozygosity(LOH) on chromosome 10?q.Fifteen of 55 cases allelic loss were detected on loci D10S 541 which located in the PTEN gene region at 10?q 23\^3 .Twelve of 55 cases were detected totaled LOH on 10?q.Conclusion\ The PTEN gene mutation is rare,loss of allelic 10?q is frequente in oligodendrogliomas,especially in high\|grade oligodendrogliomas.It could indicate that LOH on 10?q has an enhance effect in tumor progression,and chromosome 10?q harbors additional tumor suppressor genes in oligodendrogliomas.\;[

Objective: To evaluate the effect of nutritional support with low carbohydrate formula (Pulmocare, Abbott, America) in patients with pulmenary disease and respiratory failure. Methods: 60 patients were randomly divided into control group and study group. The study group was given Pulmocare and the control group was given Ensure (standard enteral nutrition,Abbott, America). The lipidemia, serum protein, PaCO 2 ,PaO 2 ,VO 2 ,VCO 2 and RQ were measured before and after therapy. Results: The patients' nutritional status of the two groups was improved significantly. The index of artery blood gas analysis was significantly improved( P

Objective:To summarize the main issues, analyze the causes and offer a strategy for AIDS preven-tion and control for all types of healthcare facilities in the health care system. Methods:184 leaders and experts of tertiary-level healthcare facilities ( provinces, cities and counties) from 30 provinces who had been engaged in AIDS prevention and control for more than five years were studied through a questionnaire including the issues and causes in AIDS prevention and control. Results: According to the results of the respondents and experts’ demonstration, the main issues were identified, including a lack of human resources in the system of disease control facilities, a lack of relevant agencies involved in AIDS response, the difficulty for AIDS patients to receive surgery and follow-up, poor detection of HIV, shortcomings in medical insurance, and so on. Conclusion: Based on the analysis of issues and causes, the paper offers strategic solutions: Clearly define the responsibilities of various health institutions in AIDS prevention and control;promote the participation of primary health institutions in AIDS prevention and control; im-prove the medical service system for AIDS patients;improve AIDS medical security policies;reform the management system of antiretroviral therapy drugs;and strengthen technical support from disease control facilities.

This article was aimed to compare the antioxidant activities of Green tea and four tree-type non-Camellia teas. The antioxidant activities of the water extract of Green tea, Eagle tea, Large-leaved Kuding tea, Shiya tea and Qingqianliu tea were evaluated with four different in vitro assays including 1,1-diphenyl-2-picryl-hydrazyl (DPPH), ferric-reducing antioxidant power (FRAP), ferrous ion-chelating (FIC) and β-carotene-linoleate bleaching assay. In addition, the polyphenol contents of different teas were estimated by the Folin-Ciocalteu assay. The results showed that Shiya tea had strong antioxidant activity; its FIC and FRAP abilities are better compared with Green tea. The Eagle tea and Large-leaved Kuding tea have better antioxidant activity. The FRAP activity of Large-leaved Kuding tea was better than green tea. The DPPH of Eagle tea and Large-leaved Kuding tea were slightly lower than Green tea, but higher than the butylated hydroxytoluene (BHT). The antioxidant ability of Qingqianliu tea was the lowest. It was concluded that Shiya tea, Eagle tea, Large-leaved Kuding tea had relatively high development value which re-quires in-depth research and promotion.

Objective To evaluate the long term effectiveness of splenectomy in the treatment of ideopathic thrombocytopenic purpura (ITP) and probe into the specific management pre and post operatively. Method We analyzed 202 splenectomized ITP patients from January 1974 to June 2001 retrospectively and divided them into the effective and non effective groups according the postoperative improvement of their clinical symptoms. Results Post operative complications developed in 18 cases (8 9%), 189 cases achieved long term follow up. Good result was achieved in 159 cases including excellent in 96 and fair in 63, surgery was ineffective in 30 cases. Six cases(3 2%) died of surgery related complications during the long term follow up. In the first week after operation platelet counts reached 100?10 9/L in 118 cases, among them 110 cases(69 2%) fell into effective group and 8 cases(26 7%) fell into ineffective group( ? 2= 19 45, P
