1.Role of 3-nitrotynosine in Escherichia coli LPS-induced vascular hyporeactivity in rats
Chinese Journal of Pathophysiology 1986;0(01):-
AIM: To observe the pathological role of 3-nitrotynosine (3-NT) on Escherichia coli LPS-induced vascular hyporeactivity in rats and the therapeutic effect of antioxidants. METHODS: Forty male SD rats weighting from 200 g to 250 g were randomly divided into four groups: the control group (n=10); LPS shock group (n=10); uric acid-treated group (n=10); melatonin-treated group (n=10). 6 h after LPS shock, phenylephrine (0.5-2.5 ?g?kg -1) was applied intravenously to all groups and the percentage increase in MAP was detected, respectively. The concentration-response curve of aorta rings from all groups rats were obtained by cumulative addition of phenylephrine (PE), and PE E_ max, EC_ 50 were calculated. The concentrations of plasma malondialdehyde (MDA), nitrate/nitrite and 3-NT were assayed in all groups 6 h after LPS shock. RESULTS: The MAP level induced by PE significantly decreased to 54.60% in LPS shock rats compared with the control (P
2.Liver X receptor and metabolic disorder in metabolic syndrome
International Journal of Pediatrics 2012;39(1):85-87,91
The liver X receptor(LXR) is one of the nuclear receptors related to metabolic syndrome.LXR plays an important role in the balance of cholesterol and lipid metabolism.LXR has been found to increase the utilization of glucose,decrease the insulin resistance,and simultaneously has an adverse effect in islet β cell.LXR influences fat cell differentiation and reduces expression of the obese gene then cause obesity.It also participates the development of non-alcoholic fatty liver and control the atherosclerosis.LXR is involved in inflammatory responses in macrophages and lymphocytes.The ability of LXR to integrate metabolic and inflammatory signaling makes it particularly attractive target for intervention in human metabolic diseases.In this review,we summarize the studies of LXR,clarify the LXR in the prospects for the treatment of metabolic syndrome.

4.Analysis of the Relative Factors and Prognosis of Upper Gastrointestinal Bleeding in Patients with Hepatic Cirrhosis
Journal of Chinese Physician 2001;0(05):-
Objective To explore the relative factors and prognosis of upper gastrointestinal bleeding in patients with hepatic cirrhosis. Methods The clinical data of upper gastrointestinal bleeding of 502 inpatients from January 1990 to September 2004 were statistically analyzed. Results Males and middle-aged patients with hepatic cirrhosis occurred upper gastrointestinal bleeding more frequently, and the most commom causes were vessel rupture of esophage or gastric varices, portal hypertensive gastropathy, and peptic ulcer. The most common complications of upper gastrointestinal bleeding were severe bleeding shock, hepatic encephaopathy, hepatorenal syndrome,etc. Drinking wine and NSAIDs were the most common inducements of upper gastrointestinal bleeding. The efficient rate of medical management was 89.84%,the death rate was 10.16%, and the most common death causes were shock of severe bleeding, hepatic encephalopathy, and hepatorenal syndrome. Conclusion Sex,age, and season,etc. were related to upper gastrointestinal bleeding in patients with hepatic cirrhosis. Bleeding causes, liver function, complications, and age, etc. were factors affecting prognosis.
5.Etiology and pathogenesis of idiopathic orbital Inflammatory pseudotumor
Chinese Journal of Experimental Ophthalmology 2012;30(5):471-475
Idiopathic orbital inflammatory pseudotumor (IOIP) is a common ophthalmic disease that severely damages the visual acuity and countenance of the patient,its etiology and pathogenesis are unclear.Many hypotheses have been proposed,including infection,autoimmunity and neuroendocrine mechanism,etc..These hypotheses reflect certain aspects of the etiology and pathogenesis of IOIP and provide information for further understanding of the disease.The research progression in the etiology and pathogenesis of IOIP was reviewed.
6.Current research of immunoglobulin G4-related orbital disease
Chinese Journal of Experimental Ophthalmology 2012;(10):949-954
In recent years,immunoglobulin G4-related disease (IgG4-related disease) has received increasingly attention in medical community as a novel clinical entity.Although its clinical manifestation varies,high serum IgG4 concentration and numerous IgG4-positive plasma c(c)ll infiltration are the common characteristics.IgG4-related disease involves many human organs,and most one is pancreas,followed by parotid gland,bile duct,liver,lung,lymph node and so on,and orbital involvement is relatively rare.Current initial research shows that there is certain association between orbital disease with IgG4,and these diseases mainly include benign lymphoepithelial lesion,idiopathic orbital inflammatory pseudotumor,Castleman ' s disease,xanthogranuloma,Rosai-Dorfman disease etc..The researching progression in the relationship between IgG4 and orbital diseases is reviewed.
7.Clinical treatment of idiopathic orbital inflammatory pseudotumor
Chinese Journal of Experimental Ophthalmology 2012;30(6):571-576
Idiopathic orbital inflammatory pseudotumor (IOIP) is a common ophthalmic disease with uncertain etiology and pathogenesis.It charactarized by chronic inflammatory cell infiltration and connective tissue proliferation.At present,its clinical treatments mainly include pharmacotherapy,radiation therapy and surgery,and the primary treating drugs include glucocorticosteroids and immunosuppressive agents.The mainstay of therapy is systemic glucocorticosteroids,although there is an increasing trend toward the use of alkylating agents,antimetabolites,monoclonal antibodies and other immunosuppressive agents.The progress in clinical treatment of IOIP was reviewed.

9.Clinical study on reducing intratracheal suction complications of mechanical ventilation patients
Chinese Journal of Primary Medicine and Pharmacy 2009;16(7):1173-1174
Objective To investigate the effective nursing measures of reducing the complications of intratra-cheal suction about mechanical ventilation patients to improve airway nursing quality. Methods 80 patients with ar-tificial air passage mechanical ventilation were divided into Control group (Group one, 40 cases) and Testing group (Group two, 40 cases) randomly. In the control group, suck at regular time after injecting normal saline solution in-to the in-airway (in order to diluted the sputum). There are improvement that nursing measures in testing group. For sample, suck sputums according to demands, choose appropriate sucking sputums tube, control the deepth of sucking sputum tube, adjust the negative pressure based on the deepth of sucking sputum tube, give pure oxygen two to three minutes before and after the suction, strengthen the airway humidfication, lubricate the sucking sputum tube with chlorotetracycline eye ointment, etc. Complications of intratracheal suction were compared in two groups. Results The comparison showed that the complications have a significant statistical difference in sputum obstruction, SpO2 de-scending to 80 percent and below during suction and airway mucous membrane traumatic hemorrhage. (P < 0.01). Conclusion The improved intratracheal suction will decrease the complications obviously like sputum obstruction, SpO2 reducing to 80 percent and below during suction and airway mucous membrane traumatic hemorrhage.
