Objective To analyze epidemiologie and injury characteristics of traffic injuries in Shenzhen through emergency department. Methods A questionnaire was pre-designed to collect data of patients admitted to six general emergency departments of six district in Shenzhen from January 2007 to December 2007 for clinical analysis. Results There were 1 328 patients with road traffic injuries, at age range of 2-84 years (average 31 years). According to occupation, most patients were local workers and migrant workers (57.8%). The accidental vehicles were mostly cars (48.5%). Most accidents (78.6%) occurred in urban streets. As for time distribution of traffic injuries, most injuries happened on Friday and Saturday (accounting for 17.8% and 18.7% respectively), especially on Friday (r = 0.166 0, P <0.01). There was central tendency around 15:35 p.m. in one day (r = 0.285 6, P < 0.01). The age of male was (32.36±8.70) years and that of female (29.96±4.32) years, with statis-tical differences (P < 0.05). Of patients followed up, 84.4% patients could work on their original jobs, 8.5% needed ehange of their jobs and 7.1% lost the ability of work. Conclusions It is neeessary to strengthen road safety education among local workers and migrant workers to improve their awareness of road safety. Traffic administrators and road safety marks should be added in the chief period and districts where road traffic injuries happen most frequently. Controlling the number of small cars may be effective to reduce traffic accidents.

Objective:To explore the extent of psychological counselors’ job burnout. Methods:171 psychological counselors were tested by MBI-HSS.Results:(1) In the aspects of demographic variables, male experienced higher cynicism(t=2.233,P

Purpose:To evaluate the effect, tolerabilily and toxic-side reactions of combined carboplatin and cisplatin with etopside in advanced non-small-cell lung cancer.Methods:From Oct. 1998 to Mar. 2000, 23 cases with advanced non-small-cell lung cancer were treated by combined carboplatin [200 mg/m 2intravenously (IV) on day 1]and Cisplatin ( 30 mg/m 2 IV on day 3～5) and etopside (100mg/m 2 IV on day 1～5) . The treatment was repeated every 3～4 weeks.Results:86 cycles were completed in the whole group. Median cycles was 4. The overall response rate was 43.48%(10/23,PR), the median survival time was 8.2 months, the 1-year survival rate was 32%. Myelosuppression was the main toxicity, The overall response rate was 86.96%(20/23). Conclusions:Our results indicate that combined carboplatin and cisplatin with etopside regimen is effective for advanced non-small-cell lung cancer.

The new rural cooperative medical system(NRCMS)has been promote quickly and successfully all over the rural areas in China,and has achieved a comprehensive coverage.However,in the process of the NRCMS emerged certain issues going against the principles of ethics.Therefore,this paper attempts to analyze current abnormal ethical issues and identify relevant countermeasures,aiming to promote the performance of the NRCMS.

Objective To explore the rationality of clinical blood transfusion since the Ministry of Health enacted the The Technical Criterion of Clinic Blood Transfusion' in 2000. Methods Retrieved the literatures on the appraisal of rationality of clinic blood transfusion published in core journal between 2000 and 2010, and analyzed the rationality of clinical blood transfusion in recent 10 years. Results In 35 literatures entered, the proportion of appropriate blood transfusion of platelet was the highest compaved with the lowest proportion of plasma. the proportion of appropriate blood transfusion in operational department is higher than that in non-operational department. The primary reason of inappropriate blood transfusion is transfusion without indications. Conclusion The proportion of appropriate blood transfusion in china is low. The government should enhance the regulation of blood usage,and the public should he educated to realize the importarce of appropriote blood transfusion in order to promote it to develop healthily.

In clinical practice,regional portal hypertension is infrequent,but it is the only type which could be cured of portal hypertension.Pancreatic diseases are the chief pathogeny of regional portal hypertension,and the obstruction of spleen vein is the basic reason.The common clinical manifestation is isolatism varicose veins of pylorus.The golden standard of its iconography diagnosis is DSA,and the treatment should follow the individual principle.The splenectomy is the basic measure for them who have UGIB or hypersplenism.This is a review about recent advance in regional portal hypertension of etiology and classification,pathology and physiology,clinical manifestation,diagnosis,radiographic examination,cure,and so on.

Magnesium and its alloys possess the features of low density,high strength and rigidity,good biocompatibility and biodegradability.Their elastic modulus is similar to human bone,which endows them with a broad application prospect in the field of orthopedic biomedical materials.This paper reviews the current research status of magnesium and its alloys as the orthopedic implant materials and as porous scaffold materials in bone tissue engineering.Methods to improve corrosion resistance of magnesium-based metals ale briefly described as well.

Objective To study the effect of Xuebijing, a Chinese traditional medicine injection, on the THP-1 cells challenged by endotoxin, and to explore whether it induces endotoxin tolerance. Methods The THP-1 cells were pretreated with Xuebijing in different concentrations (10, 25, 50 mg/mL) and times (4, 12, 24 hours), and then challenged by endotoxin. The level of TNF-α in culture supernatant was detected by ELISA assay, and the expression of TLR4 and IRAK-M mRNA were detected by Real time-PCR technique. Results There was no significant difference in TNF-α level among all the groups (pretreated with different concentrations of Xuebijing for different time) (P>0.05). Only in 50 mg/mL Xuebijing group, TLR4 mRNA was 1.547-fold increase in 24 h than in 4 h group (P<0.05). Only when pretreated for 24 h, IRAK-M mRNA was 1.349-fold increase in 50 mg/mL Xuebijing group than in control group (P<0.05). However,there was no significant difference among other groups (P>0.05). Conclusions Xuebijing can not block the release of TNF-α from the THP-1 cells challenged by endotoxin;and it does not induce endotoxin tolerance. When pretreated with high concentration of Xuebijing for long time, the expression of both TLR4 and IRAK-M mRNA is up-regulated, but its significance is not yet clear.
