Objective: To investigate the effects of fibrin glue(FS) and glutamine(Gln) on the healing of colon anastomoses after immediate postoperative intraperitoneal administration of 5-fluorouracil.Methods: Thirty two female Wistar rats were randomized into four groups.After resection of a 1-cm segment of the transverse colon,an end-end sutured anastomosis was performed.Then the rats were divided into control group,5-FU group,FS group,and Gln group.All rats were killed on the 8th postoperative day and the anastomoses were examined microscopically.The bursting pressure measurements were recorded and anastomoses were graded histologically.Results: The adhesion formation score was significantly higer in the rats of the 5-FU group than in the other groups.Bursting pressures were also significantly lower in the 5-FU group than in the other groups.Conclusion: The immediate postoperative intraperitoneal administration of 5-FU inhibited wound healing.However,FS and Gln can improve early healing of colon anastomoses after immediate postoperative intraperitoneal administration of 5-fluorouracil.

Our country has made great achievements in organ transplantation,but there still exist many problems such as shortage of organs,seriously hindering the development of organ transplantation.Family factor,one of the influencing factors of organ transplantation in our country,has the characteristics of persistence and permanency.Researches on family factors will be helpful for the healthy development of organ transplantation.Started from family factors,this paper discussed the ethical issues of organ transplantation in our country and proposed appropriate measures such as changing moral cognition,advocating family support,strengthening community family intervention,correctly dealing with family ethics relationship,in order to provide a useful reference for the development of organ transplantation in China.

Objective To observe the influence of sirtinol,a silent information regulator 1(SIRT1)inhibitor,in the cell proliferation, cell cycle progression and the expression levels of positive regulator proteins of the cell cycle including Cyclin D1,CDK4 and pRb in prostate cancer DU145 cells,and to explore the possible mechanism of SIRT1 in occurrence of prostagte cancer.Methods The DU145 cells at logarithmic growth phase were cultured in vitro and divided into control group(DMSO)and different doses (10,25,50μmol·L-1 )of sirtinol groups.The inhibitory rate of growth of DU145 cells was detected with MTT method,the SIRT1 mRNA and protein expression levels were determined by RT-PCR and Western blotting method, and the cell cycle was measured by flow cytometry.The Cyclin D1,CDK4 and pRb protein expression levels were examined by Western blotting method. Results Compared with control group, the inhibitory rates of growth of the DU145 cells in different doses of sirtinol groups were increased markedly in a dose-dependent manner(P<0.01),and the flow cytometry analysis result showed the DU145 cells at G1 phase were increased (P<0.01 ). Compared with control group, the expression levels of SIRT1 mRNA and protein in DU145 cells in different doses of sirtinol groups were decreased significantly(P<0.01);the expression levels of Cyclin D1 and pRb proteins were decreased(P<0.01),whereas the expression levels of CDK4 had no change(P>0.05).Conclusion SIRT1 inhibition by sirtinol can inhibit the cell growth of prostate cancer DU145 cells in a dose-dependent manner and arrest the cell cycle progression,and its mechanism may be related to decreasing the CyclinD1 and pRb protein expressions.

Objective To explore the effect of particulate matter (PM) 2.5 on the expression of pigment epithelium-derived factor (PEDF) protein in bronchial epithelial cells (BEAS-2B). Methods Human BEAS-2B were subcultivated, followed by low, medium and high concentrations of PM2.5 (25μg/ml, 50μg/ml, 100μg/ml) stimulation for 24 hours. The expression of PEDF protein in supernatant was ana-lyzed by enzyme-linked immunosorbent assay (ELISA), and the expression in BEAS-2B cells was detected by Western blotting. Results Compared with the control group, the expression of PEDF protein in supernatant and BEAS-2B cells induced by PM2.5 (25 μg/ml) in-creased, but no significance was found (t=-0.730, t=-1.840, P>0.05), and the expression induced by PM2.5 with the concentrations of 50μg/ml and 100μg/ml significantly increased (t>5.798, P<0.05). Conclusion PM2.5 with the concentrations of 50μg/ml and 100μg/ml could increase the expression of PEDF protein in a concentration-dependent manner both in supernatant and BEAS-2B cells.

Objective To study of the imaging diagnosis and differential diagnosis of cystitis glandularis. Methods The clinical data and imaging findings of 8 cases with cystitis glandularis proved by pathology were retrospectively analyzed with literaures re-view. Results The lesions on images appeared as nodular mass in 4 cases, diffuse in 2 cases and mixed type in 2 cases,1 case with cystic degeneration. The lesions in 2 cases obviously reduced in size after treatment. The CT value of the lesions post contrast-en-hanced scan averagely increased up to 15.8 HU compared with that of plain scan. The lesions were localized in 6 cases and diffuse in 2 cases. Conclusion cystitis galandularis has some imaging characteristics, but the final diagnosis is depended on pathology.

To make a systematic analysis on literatures concerning traditional Chinese medicine (TCM) advices in Treatise on Febrile Diseases, and summarize the main connotations of traditional Chinese medicine advices, relevant TCM advices in Treatise on Febrile Diseases were collected, screened, compared, summarized and analyzed according to TCM dosage form preparation methods, TCM administration methods, medication contraindications and nursing after TCM administration. The literatures concerning medications in Treatise on Febrile Diseases were consulted, summarized and compared to standardize medicine advices and facilitate rational clinical application of TCMs. The standard medicine advices were as follows. The boiling water for TCMs shall be tap water and well water. The decoctions that have effects in promoting blood and meridians can be boiled with wine. The decoctions containing toxic components can be boiled with honey. Some TCMs shall be boiled with special methods, e. g. Herba Ephedra that could be boiled before other medicine and skimmed. Japonica rice could be added in decoctions to measure the duration of decoctions. Different dosages were required for different forms (litre, pill, medicine spoon). Administration times, temperature and frequency shall be adjusted according to target positions, functions and stage of illness. As for dietary contraindications during medication, thick porridges are recommended, where foods impacting medicine efficacy are prohibited. Regarding nursing after medication is important to recover physical functions, particularly warm porridges can go with diaphoretic recipes, while thick porridges can go with purgative recipes. And drug efficacies shall be defined by observing urine and excrements, and blood form. In conclusion, Treatise on Febrile Diseases is the first book that discusses TCM advices and records them in details. In this study, new standard medicine advices were proposed to provide important basis for improving clinical advices of TCMs and supports for developing the TCM dispensing technology.

Under indoors simulating natural growing condition, the 4th-instar Mythimna separata larvae were fed by using poi- son leaf disk method. The effect of total ginsenosides on the protective enzymes (PPO, T-SOD, CAT and POD) of M. separata larvae was studied. The total ginsenosides could influence the protective enzymes of 4th-instar M. separata larvae significantly. After treated by total ginsenosides, the PPO activities increased firstly then decreased, and tended to equilibrium, and reached the maximum after 48 h. Furthermore, the total ginsenosides disturbed the dynamic balance of SOD, CAT and POD of M. separata larvae, and the yield of O2-* speeded. The results suggest that the total ginsenosides influence the protective enzymes of 4th-instar M. separata larvae, and disturb the original dynamic balance of protective enzymes. Consequently the insect suffers from the harm of O2-*.
