OBJECTIVE:To study the efficacy of the compound preparation of Yangshen and Chuanxiong in the treatment of cardiovascular diseases. METHODS: The effect of the compound preparation of Yangshen and Chuanxiong on blood pressure of spontaneous hypertensive rats was observed. The myocardial ischemia model was established in rats by ligating coronary artery for the observation of the effect of the compound preparation on serum creatine phosphoric acid activating enzyme (CK), lactic dehydrogenase (LDH), malonaldehyde (MDA), and hyperoxide mutase (SOD). The ischemic cerebral edema model was established in rats by carotid ligation for the observation of the effect of the compound preparation on brain water content. The experimental thrombus model was established in rats by extracorporeal circulation for the observation of the effect of the compound on thrombus weight. The model of blood stasis was established in rats by injecting them with adrenalin hydrochloride for the investigation of the effect of the compound on whole blood viscosity. RESULTS: The compound preparation of Yangshen and Chuanxiong brought down the blood pressure in model rats significantly, increased serum levels of SOD and MDA as well as brain water content, inhibited the empirical thrombogenesis, and reduced the whole blood viscosities in rats with acute myocardial ischemia. CONCLUSION: The compound preparation of Yangshen and Chuanxiong has remarkable efficacy in anti-thrombosis, improving the cerebral circulation disturbance and cerebral oxygen supply, eliminating cerebral edema and promoting blood circulation to remove blood stasis.
4.Application of mechanical stapling devices in hepatopancreatobiliary surgery
Chinese Journal of Digestive Surgery 2012;11(1):38-40
Mechanical stapling devices have been widely applied in the gastrointestinal surgery since the 1950s because of its advantages of easy manipulation,less time consumption and low incidence of postoperative complications.With modification of these devices and technical proficiency,mechanical staplers have been introduced into several surgical procedures in hepatopancreatobiliary surgery including pancreatoduodenectomy,hepatectomy,cholecystojejunostomy,gastroenterostomy,cystogastrostomy and enteroenterostomy.Currently,there are no guidelines or consensus in China concerning the use of mechanical stapling devices. Current advances in mechanical stapling devices and complications in the clinical practice are discussed in this article.

6.Challenges and thoughts on precise hepatectomy
Chinese Journal of Digestive Surgery 2011;10(1):4-5
Precise hepatectomy is the application of minimally invasive concept in hepatic surgery. There are big challenges for surgeons to choose the proper approaches to achieve the aim of precise hepatectomy. How to choose therapeutic strategy, chemotherapy, radiotherapy, liver transplantation or radiofrequency ablation? How to choose the operation type, laparoscopic surgery, transabdominal surgery or Da Vinci robot-assisted surgery? How to choose the surgical instruments during hepatectomy? Although answers for these questions are various, the principle is unchangeable, which is providing minimal injury, less blood loss, fast recovery, little expense and good prognosis. The concept of precise hepatectomy includes precise judgment of liver function and careful preparation before operation, and also the elaborate nursing and multi-disciplinary cooperation during operation, as well as the fast track surgery after operation. Precise hepatectomy requires surgeons take the safety and effectiveness of the operations into account, and the conditions of hospitals, the skills and experiences of the surgeons should also be evaluated before operation. Finally, the economic condition of the patients should be considered and proper application of advanced equipments should be emphasized.
7.Damage control resuscitation: redress the coagulopathy at the early stage
International Journal of Surgery 2008;35(10):687-690
After the concept of damage control resuscitation is introduced, in the most severely injured casualties, when the lethal triad of hypothennia, acidosis, and coagulopathy are present, resuscitation prac-tice for damage control usually focuses on rapid reversal of acidosis and prevention of hypothermia, while di-rect treatment of eoagulopathy has been relatively neglected. Recent studies have brought back to light the importance of treating the coagulopathy of trauma at an earlier stage. This review focused on the importance and the right time of treating this disorder, analyzed the methods of addressing the early coagalopathy in damage control resuscitation and gave some advices.
8.Diagnostic value of liver imaging reporting and data system on hepatocellular carcinoma
Chinese Journal of Digestive Surgery 2017;16(2):130-133
To improve standardization and consensus regarding interpreting,and reporting CT and MRI scans of the liver in patients with high-risk HCC,Liver Imaging Reporting and Data System (LI-RADS) was launched in 2011 and subsequently modified in 2013 and 2014,respectively.Major diagnostic imaging features for HCC are hyper-enhancement in the arterial phase,rapid dissection in the portal vein phase and balance phase,capsule presence and appearance,interval threshold tumor growth and tumor diameter.LI-RADS categorizes nodules recognized at CT or MRI as LR-1 (definitively benign),LI-RADS is a system of standardized criteria for interpreting liver CT and MR images of patients at risk of hepatocellular carcinoma in higher interobserver reliability and faster categorization while maintaining diagnostic accuracy.LR-2 (probably benign),LR-3 (intermediate probability of being HCC),LR-4 (probably HCC) and LR-5 (definitively HCC).According to diagnostic classification,different options for treatment recommendations are adopted by surgeons including continue standard surveillance,regular follow-up,alternative imaging method,multidisciplinary discussion,liver resection or transplantation.LI-RADS is a system of standardized criteria for interpreting liver CT and MR images of patients at risk of hepatocellular carcinoma in higher interobserver reliability and faster categorization while maintaining diagnostic accuracy.
9.Diagnosis and treatment of nonparasitic hepatic cysts
Chinese Journal of Digestive Surgery 2015;14(2):99-101
The diagnosis of nonparasitic hepatic cysts has been significantly improved with the development of imaging techniques,however,the successful differential diagnosis depends on more careful consideration.The differential diagnosis of multiple hepatic cysts and polycystic liver disease depends on the family heredity,number of cysts,combination of polycystic kidney,division and the results of B ultrasound.The differential diagnosis of hepatic cyst and hepatic cystic adenocarcinoma depends on the imaging features and results of histopathological examination.Recently,laparoscopic surgery has been widespread-ly used in the management of hepatic cystic disease,while it still cannot replace open surgery.The individualized and various treatment should be selected according to the condition of the patients.

Objective To study the liver cancer specific DNA damage response/repair/recombination gene expression profile and the difference between liver cancer tissues and their adjacent normal tissues. Methods The cDNA probes labeled with ? 32 P dATP were synthesized from total RNA of cancer tissue and adjacent liver tissues. The cDNA probes were differentially hybridized to two identical Atlas human cancer cDNA expression array membranes containing 588 known genes. A gene specific semiquantitative reverse transcription polymerase chain reaction (RT PCR) method and Northern blot were used to check the expression pattern of two known genes. Results Autoradiographic result analyzed by specific Atlas Image TM (version1.01a) showed among the 588 genes analyzed, 33 genes were related to damage response/repair/recombination and the expression of 4 genes including DNA dependent protein kinase, and DNA topoisomerase Ⅰ were found to be up regulated in liver cancer. The results of RT PCR and Northern blot confirmed the expression pattern of two genes which were detected by Atlas human cancer cDNA expression array. Conclusion The result obtained from Atlas microarray provides a liver cancer specific expression profile comprehensively and systematically. The findings about genes related to DNA damage response/repair/recombination may lead to understanding of the pathogenesis of liver cancer and the mechanism of drug resistant.
