Objective To observe the inhibitory effect of IL-4 on the IL-1?-induced rat mesangial cell proliferation, the release of PGE 2, and on the COX-2 mRNA and protein expression, so as to explore the related mechanism of anti-glomerulosclerosis. Methods Rat mesangial cell (MC) was cultured in vitro and the IL-1? -induced proliferation of MC was detected by MTT method. ELISA method was employed to measure the contents of PGE 2 in blank control group, IL-1? group, IL-4+IL-1? group, NS-398 group, NS-398+IL-1? group, indomethacin group, indomethacin+IL-1? group. The expression of mRNA and protein of COX-1 and COX-2 gene were detected by RT-PCR and Western blot, respectively. Results IL-1? could induce the proliferation of MC when the concentration was 0.1-100ng/ml in 12h, 24h and 48h. When its concentration was 2ng/ml, it had the strongest effect in 24h. All the IL-4, NS-398, indomethacin could inhibit IL-1? to induce MC producing PGE 2. The inhibitory rates are in proper order as: IL-4 (84.9%), NS-398(56.5%), and indomethacin(41.2%). Both IL-4 and NS-398 could obviously inhibit the expression of COX-2 mRNA and protein proved by RT-PCR and Western blot. Indomethacin could strongly inhibit the expression of COX-1 mRNA and protein, while only shew a weak inhibition on the expression of COX-2 mRNA and protein. Conclusion IL-4 could markedly inhibit the IL-1? -induced MC proliferation, down-regulate COX-2 gene, decrease the production of PGE 2, and thus take effect on anti-glomerulosclerosis.

OBJECTIVE:To provide reference for lung cancer therapy in the filed of TCM and offer guidance for pharmacy work. METHODS:266 lung cancer prescriptions were collected from the department of TCM of our hospital during Jan. to Dec. in 2014,in-vestigated and analyzed in respects of patient’s age,the number of TCM ingredient,the weight and number of dose,cost,drug catego-ries,the frequency of each ingredient use. RESULTS:The high-risk population of lung cancer were over 40 years old group;the num-ber of TCM ingredient were from 16 to 20;the weight of dose was from 200 g to 300 g;the average number of dose was 10.01 with 53.79 yuan in average. Top 3 TCM were tonics (16.5%),TCM for relieving cough,reducing phlegm and preventing asthma (13.5%),TCM for clearing heat(11.5%). Fritillaria thunbergii,Morus alba,Citrus reticulate and Tetrastigma hemsleyanum took up the front place in the list of frequency. CONCLUSIONS:TCM for relieving cough,reducing phlegm and preventing asthma(13.5%) and TCM for clearing heat are frequently used in TCM prescription for lung cancer;all of them are easily damaged by worms,mildew, rot and extensive diffusion of oil. The management should be strengthened.

Objective:To explore the personnel arrangement in the outpatient pharmacy by calculating working hour to provide ref-erence for the rational staffing in hospital. Methods:The daily work content and working hour of 18 pharmacists in the outpatient phar-macy of a large general hospital from January to March in 2013 were following-up observed and recorded using the working hour meas-urement. The data were input the EXcellsoftware to establish the database, and the workload in various positions was collected and sorted. The obtained relative parameters were used to calculate the needed worker number on the basis of manpower planning model. Results:The research confirmed the mean operation time for 9 work programs in the outpatient pharmacy, and the time for drug dispen-sing and distributing was detailed. The needed number of pharmacists was 13. 29 according to the calculation, plus the officer-in-charge and sanitation workers, the total number was 15. 29(approx. 16). Conclusion:The working hour measurement can scientifically de-termine the time for each job, and the workload should be used as the foundation for configuring personnel qualification and the number in outpatient pharmacy.

Objective To explore influencing factors for complete resection and operation time of endoscopic submucosal dissection( ESD) for colorectal tumors. Methods This retrospective study included 95 consecutive colorectal tumors in 88 patients whose pathological diagnosis was adenoma and carcinoma, treated with ESD at the Department of Endoscopy of the First Hospital of Jilin University from January 2013 to December 2014. Multiple logistic regression analysis was conducted on the factors related to complete resection and operation time. Results Average tumor size was 28. 7±14. 1 mm(range,8?80 mm), and the average procedure time was 80. 72±63. 90 min. The rate of complete resection was 92. 6%(88/95),and the rate of incomplete resection was 7. 4%(7/95). Multivariate logistic regression analysis revealed that fibrosis (P=0. 012,OR=52. 473, 95%CI:2. 571?1140. 438) contributed to incomplete resection. Fibrosis ( P=0. 001, OR=0. 045, 95%CI:0. 007?0. 289) ,tumor size ( P=0. 035,OR=0. 170, 95%CI:0. 033?0. 884) ,granular?type laterally spreading tumor ( P=0. 013, OR=34. 432, 95%CI:2. 138?554. 476 ) , non?granular?type laterally spreading tumor(P=0. 044,OR=31. 715, 95%CI:1. 093?919. 904) were independent factors for extending operation time of colorectal ESD. Conclusion The severer fibrosis can induce higher rate of incomplete resection. The more severe fibrosis is, the larger tumor size is, and the longer operation time is.
