With the rapid development of critical care medicine (CCM) in China, there are increases in the number of intensive care units (ICUs), the scale of one center ICU and the team. Subspecialty construction of CCM is of great concerns for personnel training as well as discipline development, and is currently one of the urgent problems that need to be resolved. Experience of CCM subspecialty construction from Europe and the United States is lacking and it is necessary to propose some opinions on innovation to construct CCM subspecialties with Chinese characteristics. We believe that CCM sub-specialties construction should be based on the core knowledge (pathophysiology) and skill (organ monitoring and support). The following 7 sub-specialties can be set up: ① acute lung injury and mechanical ventilation; ② shock, hemodynamic monitoring and treatment; ③ acute kidney injury and blood purification; ④ sepsis and anti-infective therapy; ⑤ stress, sedation and analgesia; ⑥ nutrition and metabolic support; ⑦ coagulation, immune and inflammation. The core knowledge and skills of critical care medicine will constantly be updated and enriched. Therefore, sub-specialty settings should be constantly updated as well.

To treat residual or recurrent stones after operation on hepatolithiasis conveniently and effectively, a subcutaneous permanent tunnel to bile duct (SPTBD) was established in 564 cases of hepatolithiasis by using an afferent jejunum or a well-functioned gallbladder in order to provide a postoperative way to remove residual or recurrent stones through cholangioscopy. We found that by cutting SPTBD open to remove residual or recurrent stones through cholangioscopy in 96 out of 238 followed-up cases, all the patients got good clinical effects without death or complications. The results suggest that it is a good method to establish a SPTBD during operation in patient with hepatolithiasis. It is a simple and effective way to cut SPTBD open to remove residual or recurrent stones after operation.

Objective To study relationship between hepatocellular apoptosis and glycogen contents during cold preservation-reperfusion of liver and its mechanism. Methods Rat liver models with different contents of glycogen were established and the rats were divided into 4 groups (A, B, C and D). During cold reservation-reperfusion of liver, the changes in hepatocellular apoptosis and tissue SOD, GSH and MDA were observed in the groups. Results After cold preservation for 9 h in each group, 60?min reperfusion could result in obvious apoptosis in livers. There was difference in the numbers of apoptotic hepatocytes among all the groups. At the same time, there also were significant difference in the levels of SOD, GSH and MDA in liver tissue among the four groups.Conclusion Intracellular abundant glycogen may significantly depress hepatocellular apoptosis during hepatic cold preservation-reperfusion by decressing oxygen free radicals.

Objective To investigate the effect of intracellular glycogen on mitochondrial respiratory function of the ischemic reperfusion hepatocytes and its values.Methods During liver ischemia-reperfusion in the 21 rabbits,the tissue ATP content,hepatic enzymological change,respiratory control ratio(RCR) and P/O ratio of hepatocellular mitonchondria were observed in liver glycogen content significantly different three groups.Results Rabbit liver tissue with the higher content of glycogen has shown the higher mitonchondrial ATP content,also showed the higher RCR and P/O ratio of hepatocellular mitonchondria and the slighter injury of liver function.Conclusion Intracellular abundant glycogen may significantly improve respiratory functon of mitochondria,which can play an important role in keeping the hepatocellular function well during liver ischemia-reperfusion.

Objective To establish the equation of chest CR for the estimation of age, and evaluate the significance of forensic medicine. Methods 5 measurements were selected to carry on the independent samples, and the status were analyzed by SPSS 19.0. Results The 5 measurements and age were line-related(P<0.05); Three group regression models were formulated; In a separate test, a control sample of 30 chest CR that not involved with formulating the regression equation was correctly estimated with 73.3% to 86.7% accuracy within 3 years. Conclusion The method set up in this paper can be used to estimate the age of Chinese Han adults.

Objective To summarize the clinical effects of cholecystocholangiostomy (STHG) in the treatment of hepatocholangiolithiasis and hepatic portal bile duct stenosis. Methods The early complications, clinical effects, and functions of gallbladder in a total of 135 patients, admitted since 1994 were for STHG were retrospectively analyzed. Results No early complications were observed after the operation. The contraction and concenration function of the gallblader remained basically normal. The color of gallbladder mucosa was normal,and no edema or erosion was found under choledochoscopy. Conclusions This operation not only maintained the normal physiological functions of the gallbladder and Oddi sphincter, but also the physiological flow of the bile, farthermere it prevented reflux of intestinal juice and reflax chdangitis. Because the anastomotic stoma was large, concentrated bile within the gallbladder could freely get access to the intrahepatic biliary tract, the concentration of bile acid in the intrahepatic bile duct was markedly elevated, so that the solubility of bilirubin crystal, was increased and recurrence of calculus formation eould be retarded. There fore, STHG should be considered to be an optimal operation in dealing with hepatocholangiolithiasis and biliary stenosis.

The main causes of early mortality after the earthquake are traumatic shock, hemorrhage and dehydration, and the ratios of shock and hemorrhage are high in patients with abdominal injuries. Prompt triage is very important to persons with abdominal injuries who were rescued in 48 hours after the earthquake. Primary triage should be carried out in the rescue field, and then followed by the secondary triage in the hospital. We improved the efficiency and accuracy of triage by following the principle of "5 steps, 3 categories and 1 indication". Nineteen persons with identified abdominal injuries and unstable vital signs received operation. The false positive rate was 5% (1/19), and the successful rate of the operation was 95% (18/19). During the process of rescue, the lives of the injured persons should be put in the first place. The operation should be performed under the principle of simpleness, rapidity and safeness.

Objective To investigate the therapeutic effectiveness of endoscopic self-expandable metal stent implantation for hilar cholangiocarcinoma. Methods The clinical data of 73 patients with hilar cholangiocar-cinoma who had received endoscopic metal stent implantation at the General Hospital of PLA Chengdu Command from July 2004 to July 2009 were retrospectively analyzed. The success rate of stent implantation, effective rate of jaundice release, duration of patency of the stent, survival time and postoperative complications were analyzed. Results Among the patients, 70 were successfully implanted with the stents. Unilateral metal stents were implan-ted in 62 patients, bilateral metal stents in three patients, and metal + plastic stents in five patients. The effective rate of jaundice release was 87% (61/70), the median duration of patency of the stent was 190 days, and the median survival time was 246 hours. Seven patients had complications of cholangitis, three had pancreatitis and two had bleeding. Conclusions The advantages of endoscopic metal stent implantation include minimal trauma and good efficacy in alleviating jaundice. It is the option of choice for the treatment of malignant biliary obstruction in patients with inoperable hilar cholangiocarcinoma.

Objective To establish a distinct linked emergency rescue network system in Shenzhen. Methods The current status of emergency network system in Shenzhen was studied, and some related publications in the recent years were reviewed. Results The emergency network system in Shenzhen is characterized by the following aspects: there is an effective emergency dispatch system with high authorities; the network covers every corner of Shenzhen; series of laws have been issued to ensure the proper operation of network. Conclusion The medical rescue system has developed in depth. The combination of community-based, pre-hospital and hospital rescue is effective in the whole process of emergency rescue, and shortens the rescue distance. The community-based rescue is the basic part of the system that can use the medical resources efficiently.
