1.Effect of tranilast on airway remodeling of experimental COPD rats
Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(11):-
AIM: To observe the effect of tranilast on experimental COPD rats in terms of airway remodeling. METHODS: Forty eight SD rats were divided into two groups in random: untreated model group, tranilast-treated group. Another eight rats were selected as control group. The COPD rat model was established by passive smoking and intratracheal instillation of lipopolysaccharide (LPS) and then treated with sterile saline or tranilast (400 mg?kg~ -1 ?d~ -1 ) respectively. Eight rats in each group were killed in 7th, 14th, 28th day after the beginning of proceeding. Bronchoalveolar lavage fluid (BALF) was collected, and the total and differential cells were counted. The distribution and the ratio of type I to type III collagen in the lung tissue were determined using a sirius red polarizing microscopy morphometry method. Lung tissues were observed by hemotoxylin and eosin stain, then the image analysis were made. RESULTS: The total cells and the AM ratio in BALF of tranilast-treated group significantly decreased in comparison with those in model group (P
2.Discussion on Risk in Medical Equipment Purchase and Personnel Management
Chinese Medical Equipment Journal 2003;0(11):-
In medical equipment purchasing process, massive non-price factors' influences conduce to quite quantities of risks in the medical equipment purchase. To control the risks,this paper proposes the project management, the supplier management, the equipment traceability management and related suggestions. Management on purchaser is also discussed, which mainly includes professional stress analysis and the countermeasures research.

Chinese Journal of Hospital Administration 2009;25(3):164-167
From the aspects of advantages, barriers, opportunities and challenges, this paper analyzed the environmental factors of Shanghai medical resources serving people in the Pan-Yangtze River Delta. As envisaged by the author, such services will provide medical resources information to patients from outside Shanghai, probe into feasible ways to medical insurance based on experiences drawn from serving such patients, help with the resources integration of medical systems in Shanghai, and probe into the potentials of telemedicine and distant medical e-learning, as well as improve hospital management levels and service functionality.

Bile acid can not only emulsify fat and facilitate the absorption of fat soluble substances,but also it is an important signaling molecules that plays an important physiological role by activating specific bile acid receptors.Takeda G proteincoupled receptor 5 (TGRS) is a membrane receptor of the bile acid,it can activate G-protein effectors and promote the expression of the second messenger and activate a variety of signal transduction pathways to exert physiological functions.The obstructive jaundice bile acid can cause a series of pathophysiological reactions through activating TGR5,which plays a significant role in the obstructive jaundice.In this article,the latest researches about the function and molecular mechanism of TGR5 in obstructive jaundice were reviewed in order to provide a new idea for exploring the new method and strategy to cure the disease.

Objective To investigate the function of donor-derived dendritic cells (DCs) treated with NF-?B decoy in prolonging murine cardiac allograft survival time.Methods Donor bone marrow- derived DCs were treated with NF-?B decoy in vitro.Heterotopic abdominal heart transplantation was performed from BALB/c to C57BL/6 mice.Recipients were grouped according to different pretreat ments as follows:(1) Control group,infusion of PBS (0.2 ml) alone intravenously via the portal vein 7 days before heart transplantation;(2) CsA group,treated with sub-therapeutic CsA only for 7 days (10 mg?kg~(-1)?day~(-1)) through intraperitoneal injection after transplantation,and the same as control group before transplantation;(3) Control DCs group,infusion of only cultured 5th-day recipient DCs untreated with NF-?B ODN decoy;(4) Treated DCs group,infusion of recipient DCs pretreated with NF-~cB ODN decoy;(5) Combined treatment group,infusion of recipient DCs treated with NF-~cB ODN decoy before transplantation and intraperitoneal injection of sub-therapeutic CsA for 7 days (10 mg?kg~(-1)?day~(-1)) after transplantation;(6) Third party donor group,C3H/HeJ mice used as donor, and recipient (C57BL/6) was treated the same as combined treatment group.Every group had 8 mice and graft survival time was observed.Cytokines (IL-2,INF-?,IL-4 and IL-10) in recipient serums were analyzed by ELISA at 7th day after transplantation.Results The graft mean survival time (MST) in control group,CsA group,Control DCs group,treated DCs group,combined treatment group and third party donor group was 7 days,10.3 days,7.6 days,21.4 days,53.6 days and 9 days,respectively.There was significant difference in MST between treated DCs group and control group or control DCs group (P
9. Drug-eluting stenting for Wingspan in-stent restenosis of vertebral artery
Chinese Journal of Cerebrovascular Diseases 2010;7(7):373-377
Objective: To investigate the feasibility and safety of drug-eluting stenting for Wingspan in-stent restenosis Methods: Firebird drug-eluting stenting was used to treat two patients with Wingspan in-stent restenosis (localized restenosis >70% at vertebral artery V4 segment). One of them was a symptomatic case, and the other had contralateral vertebral artery occlusion and bilateral posterior communicating artery hypoplasia. The stents passed through the restenotic site, and they were released under the pressure of 911.93 to 1013.25 kPa, maintaining for 15 seconds. Results: All the stents were successfully released in place. Angiography showed that there was no significant residual stenosis immediately after the procedure. There was no discomfort in patients after the procedure. The patient's preoperative symptom of repeated vertigo attacks was disappeared. No clinical ischemic event occurred in the two patients after following up for more than 6 months. Six months after the restenting, DSA re-examination showed that there was no significant restenosis in one patient. Conclusion: Using drug-eluting stents for in-stent restenosis after Wingspan stenting is technically safe and feasible. However, selection criteria of patients and efficacy of a larger sample study will be needed.

Objective To study the effects of tumor necrosis factor-?(TNF-?) on hypermetabolism of skeletal muscle protein in rats with chronic obstructive pulmonary disease(COPD) and explore the mechanisms. Methods Forty-five SD rats were randomly divided into normal control group,COPD group and COPD +TNF-? group(n=15).Rat COPD models were established by passive cigarette smoking in COPD group and COPD +TNF-? group.After dissecting and isolating the extensor digitorium longus(EDL) muscles,the EDL muscles were either cultured with media containing 10 ug/L recombinant rat TNF-? or without TNF-?.The subsequent changes in ubiquitin mRNA and protein levels were determined by real-time quantitative PCR and Western blot,respectively. Results The expressions of ubiquitin mRNA and protein of COPD group and COPD+TNF-? group were higher than those of normal contro1 group(P
