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

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.

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

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.

Objective] To explore the treatment of Lanshi Micang disease with tumors related diagnosis and treatment method, in order to have a more comprehensive understanding of anal fistula, so as to broaden the mind, improve the clinical efficacy. [Method] FromLanshi Micang-Anal Fistulaof eight prescriptions for treatment of hemorrhoids and analysis, on the basis of combining the characteristics of compatibility with tumors inDongyuan effect testand the specific prescription, made analysis of anal fistula, diagnosis and treatment of anal fistula for the study of LI Dongyuan thought. [Results] LI Dongyuan from dampness, heat, wind, dryness four on the treatment of anal fistula, with angelica, Gentiana and blood dryness of medicine, to Shufeng pain, Xinrun and blood on regulation of syndrome treatment, paid attention to diet to restore the anal fistula. [Conclusion] LI DongyuanLanshi Micangis rich in content, the treatment of anal fistula has experience, as of today, the diagnosis and treatment on anorectal diseases of clinical thought still has important guiding significance.

Objective To compare serum protein fingerprint among Uygur patients with thyroid cancer and benign thyroid nodules, and Han patients with thyroid cancer, and to screen ethnic-specific protein markers of thyroid cancer. Methods Using the technology of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), the protein expression profiles of Uygur and Han patients with thyroid cancer and Uygur patients with thyroid nodules were established and compared by image analysis software between two groups. Liquid chromatography-mass spectrometry/mass spectrometry coupling techniques ( LC-MS/MS) were used to identify differential protein. The protein′s name, cellular localization and functional classification were searched in Swissport database. Results There are 11 differentially expressed proteins by comparison of sera in Uygur patients with benign thyroid nodules and thyroid cancer, in which complement C3 and C4b levels were down-regulated in the serums of Uygur patients with benign thyroid nodules, and 9 proteins such as heme-binding proteins etc were up-regulated. There are 7 differentially expressed proteins by comparison of serums in Uygur and Han patients with thyroid cancer, in which transferrin level was up-regulated in the serum of Uygur patients with thyroid cancer, and 6 proteins such as cytokeratin-1 etc were down-regulated in serum of Uygur patients with thyroid cancer. Conclusion Combined screening of multiple labelled proteins including heme-binding protein,α2-macroglobulin, and transferrin protein etc may provide the basis for the diagnosis of thyroid cancer in Uygurs and Hans.

Objective To investigate the histogenesis and clinicopathologic features of carcinosarcoma of the urinary bladder. Methods Two cases of carcinosarcoma (one man and one woman)were included.They were admitted to hospital with discontinuous,painless,macroscopic hematuria.Clinicopathalogic features of all findings of the 2 cases were reviewed. Results Cystoscopy of both cases showed that the tumors displayed polypous or cauliflower-like shape,and grew invassively.CT examination of the bladder wall confirmed the presence of parenchymatous tumor.Both of the 2 cases underwent partial cystectomy.Intraoperative examination showed the tumors were similar to carcinoma of bladder.Histopathology showed biphasic neoplasms with distinct high grade epithelial and mesenchymal components.Morphologic characteristic of the tumor was abnormally proliferative and the mitotic figures could be seen.One of the patients died within 11 months and the other,16 months following the operation. Conclusions Carcinosarcoma of the urinary bladder is a kind of rare malignant tumor that is most often in an advanced stage at presentation and has an unfavorable prognosis. It should be identified promptly and treated appropriately.Those who have discontinuous,painless,macroscopic hematuria should be warned of the risk of the disease.
