Chinese Journal of Health Management 2009;3(3):166-169
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.

3.Inhibitory effect of lead acetate on TRPA1 channel in mice and humans
Chinese Journal of Pharmacology and Toxicology 2016;30(9):949-954
OBJECTIVE To investigate the inhibitory effect of lead acetate on transient receptor potential A1(TRPA1)channel. METHODS TRPA1-mediated calcium influx in mice dorsal root ganglion(DRG) neurons and HEK293 cells expressing nouse TRP1 (mTRPA1) and human TRPA1 (hTRPA1) was recorded by intracellular calcium imaging. TRPA1-mediated currents were detected by two-electrode voltage clamp. RESULTS Lead acetate 3.0 and 10.0μmol·L-1 inhibited external calcium influx in DRG neurons by(36.7 ± 4.1)% and(79.4 ± 3.1)%(n=5),respectively. The inhibitory effect of lead acetate on hTRPA1-mediated current was concentration-dependent. Lead acetate 0.3, 1.0, 3.0, 10.0 and 30.0μmol · L-1 inhibited the amplitudes of currents by(1.0 ± 0.7)%,(11.6 ± 0.8)%,(57.7 ± 3.2)%,(93.6 ± 2.6)%and(91.2±2.0)%(n≥4),respectively,with the IC50 2.4μmol·L-1. CONCLUSION TRPA1 channel may be an endogenous target of lead. Lead acetate inhibits TRPA1 channel at a very low concentration.

5.Bone marrow cell transplantation combined with transmyocardial revascularization and off-pump coronary bypass grafting: three-in-one surgery on ischemic heart disease
Journal of Peking University(Health Sciences) 2003;0(04):-
SUMMARY A 61-year-old male patient, with the history of premier myocardial infarction and CABG surgery, experienced recurrent unstable angina. Angiography showed triple vessel disease and vein grafts obstruction. The patient underwent a re-do OPCAB + TMLR + bone marrow mononuclear cell (BM-MNCs) transplantation on Nov. 8, 2004. BM-MNCs were isolated with standard gravity gradient method and the final implanted cell number was 12.06?108. Peri-operative data were similar to those of single OPCAB or re-CABG. The patient recovered promptly without recurrence of angina or infarction. Six-minute walking distance increased significantly (366 m to 493 m). Several imaging examinations reveal improved left cardiac function (LVEF improved from 23.75% to 52% in MRI) and diminished MI area. The results reveal that bone marrow cell transplantation, combined with TMLR and OPCAB is safe and might be effective in improving heart function for patients with IHD.
6.Role of Free Radicals in Lung Cancer Induced by Physical and Chemical Factors
Journal of Environment and Health 1993;0(01):-
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.
7.Effects of probucol on the metabolism of high density lipoprotein cholesterol and their mechanism
Chinese Pharmacological Bulletin 2003;0(11):-
Probucol is a hypolipidemic agent with a unique pharm ac odynamic and clinical profile. It has a significant antiatherosclerogenic role a lthough it causes a marked decrease in serum high-density lipoprotein (HDL)-ch olesterol levels. The metabolism of HDL in vivois unclear. Some preliminary investigations suggest a beneficial effect in enhancing reverse cholesterol tra nsport which contributes to antiatherosclerosis of probucol. This paper reviews the mechanism of HDL-lowering effects of probucol.

Acta Anatomica Sinica 2002;0(06):-
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.

Chinese Journal of Hepatobiliary Surgery 2011;17(7):527-530
Primary hepatic carcinoma (PHC) is one of the most common cancers worldwide and is the leading cause of death in China. Multidisciplinary treatment is widely accepted as the way to improve the prognosis of PHC, and non-surgical therapy now plays a more and more important role. The purpose of this article is to review the current status and progress of non-surgical treatments of PHC, such as TACE, local ablation, radiotherapy and systemic therapy.
