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 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.

Objective To investigate the mechanism of acupuncture in anti-depression. Methods 100 depressive patients were randomly divided into acupuncture group and Amitriptyline group, 50 cases in each group. They were respectively treated by acupuncture at Neiguan (PC6), Sanyinjiao (SP6), Baihui (DU20), Fengchi (GB20), and oral western meicine. The needles were manipulated once every 20 minutes and treatment was given once a day. HAMD score and levels of serum cell factors of two groups were observed. Results Serum levels of interleukin 1? (IL-1?), interleukin-6 (IL-6) interleukin-2 (IL-2) and tumor necorsis factor-? (TNF-?) in depressive subjects before treatment were significanly higher than that of nomal subjects (all P

Objective To study the effects of Ginkgo biloba extract(EGb) on the volume of cerebral infarction and expression of caspase-3 in ischemic-reperfusion rats.Methods Setting up the brain ischemic and reperfusion model in rats by Nagasawa way.Both groups rats treated with small dose of EGb and large dose of EGb were injected intraperitoneally with EGb 50 mg/kg and 100 mg/kg at 30 min before the trial and 1 h after cerebral ischemic respectively.The infarction volume and caspase-3 expression were detected by TTC staining and immunohisto-chemistry.Then the results were compared with ischemic-reperfusion group.Results In groups treated with small dose of EGb and large dose of EGb,infarction volumes [(83.4?2.9)mm3,(37.0?2.5)mm3] were smaller obviously than that in the ischemic-reperfusion group [(138.8?6.1)mm3](all P

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.

Objective To investigate health behavior level and self-efficacy in patients underwent coronary artery stent implantation,and to discuss the relationship between health behavior and self-efficacy and to offer proof to the intervention strategy of health behavior.Methods HPLP Ⅱ,self-efficacy questionnaire were used as main tools.106 patients underwent coronary artery stent implantation were investigated.Statistics analyses were performed using the Statistical Package for Social Science(SPSS)13.0.Results (1)The score of total HPLPⅡwas 130.08±21.25,the range of that was 84～180.The health behavior level of47.2%patients was general or worse,and that of 52.8%patients was good or better.(2)The score of self-efficacy was 71.37±16.32,the range of thatwas 38～110.(3)There were significant positive relationship in the scores of total HPLP Ⅱ and the six elements,and self-efficacy.The correlation coefficient was 0.389～0.916(P＜0.01).Conclusion The health behavior level of patients underwent coronary artery stent implantation was not in an ideal state.Self-efficacy has a positive effect on health behavior.The importance motivating factor should be attached to nursing practice and education by medical staff,and medical staff should establish and supervise to carry out corresponding intervention measure.

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.

Objective To investigate the effects of early pregnancy exposure to hazardous indoor air pollutants due to interior decoration and hyperthermia on neurobehavioral development of postnatal rats.Methods Twenty-two pregnant rats were randomly divided into 4 groups.Each group was placed in pollutants cabinet,hyperthermia cabinet,hyperthermia+pollutants cabinet and empty cabinet respectively for 2 h per day for 10 d since their pregnancy.The weight and neurobehavioral development of postnatal rats were observed at different time points.The number of apoptotic and dead neurons in the CA1 region of hippocampus was observed in postnatal rats.The expression of the NR1 subunit of NMDA receptor of hippocampal neurons was also detected.Results Indoor pollutants and hyperthermia could accelerate apoptosis and necrosis of hippocampal neurons in CA1 region of postnatal rats and increase the expression of NR1 subunit of NMDA receptor.Furthermore,hazardous indoor pollutants and hyperthermia could induce remarkable influences on postnatal rats’ neurobehavioral development,learning and memory capability.Indoor pollutants combined with hyperthermia aggravated these effects.Conclusion Exposure to environment of the hazardous indoor pollutants especially combined with hyperthermia during early pregnancy has remarkable influences on the nervous system of postnatal rats.
