ObjectiveTo study the method,indications, advantage and shortcoming of laparoscopic repair of inguinal hernia. MethodsFrom Jun. 1995 to Jun. 2000,50 patients with inguinal hernia were treated with laparoscopy. There were 34 indirect inguinal hernia, 9 direct inguinal hernia and 7 concealed hernia. The transabdominal preperitoneal laparoscopic mesh repair of hernia(TAPP) was performed in 34 patients. Closure of the internal orifice of hernia was performed in 7 patients. Totally extraperitoneal repair was performed in 9 patients. ResultsAll cases were operated successfully. The mean operation time was 59.3(15～180) mins. The average length of postoperative stay was 5.4(3～7)days. There were no death record and no conversion operation. There was one early failure owing to the use of too small a piece of mesh. There has been no long-term recurrence. ConclusionThe results indicate that mesh repair of hernias is a satisfactory technique with a low recurrence rate and a low major complication rate.

Objective To establish the effect of curcumin on PTX-resistant esophageal cancer cell line EC9706/PTX and to investigate the mechanism of curcumin on the epithelial stromalization (EMT) of EC9706/PTX cells.Methods EC9706/PTX cells were established by medium concentration intermittent method.The drug resistance index and cross resistance were measured by MTT assay.The inhibitory effects of different concentrations of curcumin on EC9706/PTX cell proliferation were detected.The effects of curcumin on the morphological changes,migration and invasion of EC9706/PTX cells were examined by cytostatic staining,scratching and transwell invasion assay.The effects of curcumin on the expression of E-cadherin,N-cadherin,vimentin and fibronectin in EC9706/PTX cells at mRNA and protein levels were detected by fluorescence quantitative PCR and Western blot.The effect of curcumin on the expressions of NF-κB p65 and Snail in EC9706/PTX cells were detected by Western blot.Results The drug resistance index of EC9706/PTX was 28.4,which was cross-resistant to cisplatin and doxorubicin.Curcumin could inhibit the proliferation of EC9706/PTX cells.The migration and invasion of EC9706/PTX cells were significantly decreased under the action of curcumin at 20 μmol/L concentration.Fluorescence quantitative PCR and Western blot analysis showed that the expression of Ecadherin was down-regulated and the expression of N-cadherin was up-regulated,and curcumin reversed this phenomenon.Western blot analysis showed that the expression of NF-κB p65 and Snail protein was enhanced after PTX-resistant generated in EC cell,but curcumin reversed this phenomenon.Conclusion Curcumin can inhibit the proliferation,migration and invasion of EC9706/PTX cells.The mechanism maybe that curcumin inhibits the NF-κB-Snail pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
