Purpose:Our experiments are dealing with the affect of docosahexaenic acid(DHA) in doxorubicin to cytoxicity effect of MDA-MB-435s, which is of the anti-human breast cancer and whether it is one of the effect mechanisms that it via the lipid peroxidation of DHA.Methods:Add different match such as anti-cancer drugs?PUFAs?oxidan system of sodium ascorbate and ?-methy-1.4-naphoqui-none?antioxidant of Dl-?-tocopherol and so on to the culture cell line of MDA-MB-435s each 24 hours for 6 days, estimate MDA by TBA with cell extracts and estimate the contents of NO via nitrite salt spectrophotography, then draw out a dosage-effect correlation straight line among contents of MDA,NO and cytoxicity. Mitox is used as contraposition to the peroxidation of ADM which is enhanced by DHA for peroxidation of mitox is low.Results:There have been obvious changes on the contents of MDA of the lipid peroxidation has paralled increased while NO has decreased. There is recitilinear correlation relationship among the contents of MDA and NO from cell extracts and the cytoxicity.Conclusions:It is obvious that DHA can add the cytoxicity of cell line of MDA-MB-435s with ADM, particularly after add non-cytoxicity oxidant. It is lipid peroxidation of oncocyte that one of the mechanisms of DHA can enhance anti-breast cancer effect of ADM.

Objective To investigate the health knowledge and behaviors related to traditional Chinese medicine (TCM) among the elderly of communities in national TCM health education pilot area of Zhejiang province and provide reference for TCM health education. Methods A survey about the health knowledge and behaviors status related to TCM was made among 600 elderly people in Gongshu District. The survey included demographic characteristics, health knowledge of TCM and health behaviors related to TCM. The univariate and multivariate analyses were used for analyzing the health knowledge and behavior status and influencing factors of the elderly. Results The awareness rate of knowledge about TCM health knowledge in elderly was 94.7%, the qualified rate of TCM behaviors was only 31.6%. It showed that the qualified TCM behaviors among the elders were significantly different in those of different economic status and physical exercise situation (χ2=6.606, 10.243, P=0.037, 0.001). The results of logistic regression model showed that the protective factors of qualified TCM behaviors were 60-year old and good physical exercise (OR=1.836, 2.249) and the risk factor was moderate economic status (OR=0.539). Conclusion The awareness rate of TCM health knowledge in Gongshu District was high, but the qualified rate of TCM behaviors was low. The age, economic status and physical exercise situation are the influencing factors of TCM behaviors.

Objective To investigate the factors and the preventive methods of gastrointestinal leakage.Method 32 cases of gastrointestinal leakage from 1996 to 2001 were analyzed retrospectively.Results In 32 patients,19 cases were benign diseases and 13 cases were malignant diseases.25 cases were selectively operation and 7 were emergency operation, 11 cases treated by re-operation and 21 cases by other methods.24 cases were cured and 8 cases were died.Conclusions Main cause of leakage was operative method unsuitable.Anastomostic skill was deficiency,local condition was bad and ignored postoperative treatment and so on.Preventive methods should be selected to decreasingintestinal leakage.

Objective To explore the expression of tumor necrosis factor (TNF) mRNA, TNF and TNFR in the gallbladder mucosa which developed from hyperplasia, dysplasia to carcinoma, and to further discuss the relationship between TNF and pathogenesis of gallbladder carcinoma.Methods In situ hybridization and immunohistochemistry were used to determine TNF mRNA, TNF protein and TNFR protein expression in hyperplasia, dysplasia and carcinoma of gallbladder. Results ①No one of 20 cases of gallbladder hyperplasia was found to express TNF mRNA, while 4 of 20 (20%) cases of dysplasia and 18 of 20 (90%) cases of carcinoma were found to express TNF mRNA (P

Objective To study the clinical effects of the clavicular hook plate in treatment of acromioclavicular joint dislocation. Methods 37 cases with the acromioclavicular joint dislocation surgery were carried out.Results After internal fixation for 6 to 12 months, remove the plate, and then follow up for 3 to 18 months. According to the grading standards in shoulder joint function by Karlsson ,31 cases of A grade,4 cases of B grade,and 2 cases of C grade,the excellent rate is 94.6%. Conclusions Internal fixation with clavicular hook plate is a good method in the treatment of acromioclavicular joint dislocation.

During 14-17th days, the duodenum of the rat fetus was composed of stratified epithelium and peripheral mesenchyme. On 18th day, the mesenchyme began to protrude toward the basal aspect of the epithelium, resulted in the formation of primary villi. At the sametime, goblet cells and the primordia of intestinal glands appeared. The number of goblet cells,which located at the surface of the villi, increased gradually with the fetus age, whereas after birth the goblet cells decreased with the development and maturation of intestinal glands. From 19th day till 3-4 weeks after birth, the shape of villi changed continuously, and attained to the adult shape in 4th week.

Objective To investigate the nursing of replantation methods of sea-water soaked rotated avulsion amputated fingers.Methods There were 8 cases (16 fingers) with sea-water soaked rotated avulsion amputated fingers.5 cases were replanted by synchronic replantation method,the other 3 cases were replanted by traditional replantation method.We adopted complete debridement and high quality vascular anastomosis during the operation,and give hyperbaric oxygen therapy and anticoagulant treatment post-operation.Results There were 15 survival fingers in 16 replanted fingers.The survival rate was 93.75％.After follow-up for three months to two years,the total good rate was 87.5％.No wound infection and nonunion of fracture occurred.The outline of the fingers was satisfying and patients felt well.The twopoint discrimination was 3～6 mm after 3～24 months follow-up.Conclusions The injury of sea-water soaked rotated avulsion amputated fingers is complicated and the replantation operation is difficult.but if we can adopt individual measure according to the actual circumstance,it is possible that the sea-water soaked rotated avulsion amputated fingers can survive.

Objective To evaluate the curative effect and safety of mild hypothermia on patients with traumatic brain injury. Methods According to the cochrane systematic review methods , the data bases such as Cochrane, Pubmed, Embase, CBM, CNKI, Wanfang and VIP database were searched. The quality of included documents were assessed to extract meta analysis data. Results Compared to the control group, there was no statistically significant difference in patients treated by hypothermia for 3 days or less in mortality , but the difference was statistically significant after the summary [RR=0.74, 95%CI 0.64~0.85,P<0.000 1]; And there was no statistically significant difference in improving neural function of patients treated by hypothermia for < 3 days , but hypothermia improves the prognosis after the summary [RR=1.40,95%CI 1.24~1.59,P<0.000 01]. The difference was statistically significant in the incidence of pneumonia (P=0.007), there was no statistically significant difference in the incidence of arrhythmia (P=0.06), but the difference was statistically significant after sensitivity analysis. Conclusions Patients treated by hypothermia for < 3 days is not valid for clinical outcomes , the duration of the treament up to 3 days may not reduce mortality rates, but can improve the prognosis, lasts longer than 3 days or until the pressure back to normal, reducing the mortality rate, improve the neurological prognosis;but increased incidence of pneumonia, whether to increase the rate of cardiac arrhythmias have yet to be determined.

Objective Mild hypothermia provides protection for the brain and improves prognosis in the treatment of severe traumatic brain injury, which is widely acknowledged.The article aimed to analysis the prognosis and complications of long-term and short-term mild hypothermia on patients with severe traumatic brain injury. Methods According to the cochrane systematic review methods, thorough search was carried out in databases including Cochrane, Pubmed, Embase, CBM, CNKI, Wanfang and VIP.Eval-uation was made on the quality of selected documents, and Revman5.2 software was applied for meta analysis after data extraction. Results Long-term mild hypothermia achieved improved prognosis compared to short-term mild hypothermia ( GOS score 4 ~5 ) [RR=1.37, 95%CI (1.14, 1.64), P=0.0006].No significant difference was found between these two therapies in pneumonia in-cidence (P=0.94), arrhythmia incidence ( P=0.54) and stress ulcer incidence (P=0.99). Conclusion In comparison to short-term hypothermia therapy, long-term mild hypothermia therapy improved the prognosis of patients with severe traumatic brain inju-ry without obvious increase in the incidence of pneumonia, arrhythmia and stress ulcer.
