Objective To develop a method for nou-invasive risk model that can be used in health management system and primary healthcare centers. Methods Based on systematic phenotype measurement and modified superviser-based machine learning, an applicable and low-cost method for non-invasive disease risk prediction model was developed. Invasive risk assessment model for Chinese isehemic cardiovascular diseases (ICVD) was used as a supervised standard reference to provide evidence based non-invasive model with skin resistance on 24 acupeints. Results A total of 4606 cases from a physical examination system were collected to develop the model. For those reasonable evaluation indeies, the coincidence of non-invasive with invasive risk prediction model was > 90% on average level. Conclusions This method could be used to develop non-invasive risk assessment model for the common diseases.

[Objective]The clinical efficacy of endometriosis pelvic pain using traditional Chinese medicine in cycle treatment is discussed in the paper.[Methods] Forty patients of endometriosis diagnosed by chromatic colour type-B ultrasound or 1aparoscopy with typical dysmenorrhea were treated for three months in cycle therapy with traditional Chinese medicine based on dispersing liver,clearing away heat and activating blood circulation.The pain symptoms are evaluated before and after therapy per month.[Results]After three months treatment of traditional Chinese medicine,the diversified bellyache was significantly relieved and dysmenorrhea score was alleviated from 4.83?1.6 to 2.85?2.23(P

The free radicals are some substances which have important influence on the human health. They both have salutary and harmful aspects to the human health. The role of free radicals in the lung cancer induced by physical and chemical factors such as smoking, occupational dust particles, metal ions, quartz, asbestos were briefly discussed in this article.

Objective To study the value of blood glucose changes and the severity of the disease in patients with the systemic inflammatory response syndrome(SIRS).Methods In 328 SIRS patients without diabetes,intravenous blood glucose was monitored before open intravenou channel and subsequently 3~8h after intervals.The blood glucose was reviewed if glucose was abnormal 24h later.Results The blood glucose was higher than normal in 287(87.5%)patients with SIRS,of which 44 cases were death(13.4%).The higher the blood glucose level was,the higher the mortality rate was.Conclusion Blood glucose of patients with SIRS was elevated.If the blood glucose was 3 times higher than the normal,patients with SIRS had a higher mortality rate.

The effects of zymosan-activated plasma(ZAP) on the lipid peroxides(LPO) content, the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px) in lung lymph and their relationship to lung injury were studied in control (with normal leukocyte count) and leukopenic goats. In the control goats, after ZAP infusion, LPO production elevated, that was coincided with the increase of lung lymph flow (QL), and the clearence rate of lung lymph protein (LLPC). SOD activity was also elevated, but GSHpx activity was inhibited. In leukopenic goats, ZAP challenge caused an increase in LPO production, but its content was lower than that in control goats. No marked change was observed in QL and LLPC. The results suggest that: (1) Leukocytes and oxygen free radicals are involved in the pathogenesis of lung injury due to ZAP infusion; (2) Leukocytes play an important role in producing oxygen free radicals.

Objective To investigate the pathological changes of ultrastructure of mucosa in various bronchial segments from type 2 diabetic patients. Methods Sixteen cases of type 2 diabetic patients were selected,2-3 pieces of bronchial mucosa and submucosal tissue of the lesion were taken from various bronchi during bronchoscopy and these samples were observed under a transmission electron microscope. Results The basal lamina of bronchial capillary were diffusely thickened and mostly showed onion-skin like change,protein deposited around and mixed with basal menbrance;irregular highly electron dense materials were found to deposite around capillary,capillary lumen became narrow or even collapsed,neutrophilic leucocyte marginated in lumen and adhered with endothelium;protein deposited in the interstitial;endothelial cells and pericytes had dark cell changes.The cistern of rough endoplasmic reticulum dilated and vesicle formed.Conclusion Bronchial mucosa and its surrounding tissues show characteristic pathological changes of diabetes,bronchial is also the target organ of chronic diabetic damage.

Congenital cataract is responsible for approximately one tenth of childhood blindness worldwide.Generally,cataract includes three inheriting types:autosomal dominant,autosomal recessive or X-linked.The identified genes so far for hereditary cataracts in both human and animal model mainly include encoding structural lens protein,gap junction protein,membrane protein and regulatory protein involved in lens development.Crystallins are the major structural protein of the lens.Mutation in the crystallin genes can result in lens opacity.Understanding of the mechanism of hereditary cataract may also be helpful for us to understand the involvement of environmental and nutritional factors in the process of lens opacification.The function of the crystallins proteins,the mutations in crystallin genes and associated phenotypes are summarized.

Objective To study the effect of chitosan on the growth of the in vitro cultured retinal nerve cells. Methods The retinal nerve cells of SD baby rats were cultured in vitro. The effects of chitosan at 0.065%,1.25%,2.5%,5%,10%,15% on the growth of the retinal nerve cells were measured by MTT method. The blank control group was created. Results 1.25%,2.5%,5%,and 10% chitosan could obviously promote the growth of retinal nerve cells,and 10% chitosan was the optimal concentration for the growth of nerve cells. Conclusion Chitosan can effectively promote the growth of retinal nerve cells,and it is necessary to undertake the further study of Chitosan.

Technology and technique of coronary artery stent have been developed to a certain degree, restenosis rate of metal stent reduces to 15%, but coronary artery stent is still difficult for long-term effect of interventional therapy on coronary atherosclerotic heart disease. Drug-eluting stent is newly discovered during recent years, while it is prospect for preventing restenosis postoperatively. Although clinical efficacy of drug-eluting stent is encouraged, indication is still simple. In addition, some events related to drug-eluting stent remain poorly unknown. This study was designed to compare security between drug-eluting stent and metal bared stent, analyze major factors correlated with security of drug-eluting stent, and investigate the development of drug-eluting stent.
