采造务、堡寨、弓箭手:北宋对西北吐蕃居地的开发与开拓

北宋对西北吐蕃居地的开发与开拓可分为三个阶段:第一阶段(960-1037),以采伐森林资源为主,虽然宋廷反对开边,但采造务及堡寨的设置仍然使北宋的实际控制范围沿渭河谷地向上游推进;第二阶段(1038-1071),北宋推行弓箭手屯田与修筑堡寨相结合的屯田进筑政策,将实际控制范围渐次向吐蕃部落居地推进;第三阶段(1072-1127),北宋实行武力开边政策,创设熙河路,将西北吐蕃居地纳入版图。北宋对西北吐蕃居地的开发与开拓是相辅相成的,自然资源的开发为边疆开拓奠定物质基础,边疆的开拓又为自然资源开发提供新的空间,二者相互结合,取得显著成效。

The Effects of Microwave Ablation and Surgical Resection on Hematogenous Dissemination of Cancer Cells in Treating Patients with Small Primary Hepatocellular Carcinoma

OBJECTIVE To conduct a comparative study of the effects of treatment using microwave ablation versus surgical resection on hematogenous dissemination of cancer cells, and on the level of immune cells of the peripheral blood in patients with small primary hepatocellular carcinoma (PHC,≤5 cm). METHODS Forty patients with small PHC (maximal diameter≤5 cm) were divided into a microwave group (19 cases) and a surgical operation group (21 cases). A real-time (RT) quantitative nested RT-PCR examination was performed for peripheral blood alpha-fetoprotein (AFP) mRNA. Studies were conducted to determine the level of CD3, CD4, CD8 and CD4/CD8 cells and for liver function at 30 min before, and 30 min,1 day and 3 days after the treatment. RESULTS Compared to the value before ablation, no obvious changes of CD3, CD4, CD8 and CD4/CD8 cells were found in patients of the microwave group within 7 days after ablation, but CD3, CD4 and CD4/CD8 cells in the operation group were lower compared to that before operation. The copy number of AFP mRNA in the peripheral blood samples of the patients of the 2 groups before operation was determined in 67.5% of the patients (27/40). There was an rise in the expression after treatment but no statistical difference was found in comparing the 2 groups. Follow-up of the patients was conducted for 1 to 16 months. For patients with continuous expression of peripheral blood AFP mRNA, the possibility of relapse and metastasis was increased. CONCLUSION Surgical resection or microwave ablation can cause more exfoliation of hepatoma carcinoma cells in the peripheral blood of patients with small PHC. The immune function of peripheral blood cells decreased in the patients after surgical resection, however, the immune function was better protected following microwave ablation. Microwave ablation causes minor reduction in liver function, and the treatment method presents a definite value for PHC therapy.

Factors associated with time to laparoscopic cholecystectomy for acute cholecystitis

AIM: To determine patient and process of care factors associated with performance of timely laparoscopic cholecystectomy for acute cholecystitis. METHODS: A retrospective medical record review of 88 consecutive patients with acute cholecystitis was conducted. Data collected included demographic data, co-morbidities, symptoms and physical findings at presentation, laboratory and radiological investigations, length of stay, complications, and admission service (medical or surgical). Patients not undergoing cholecystectomy during this hospitalization were excluded from analysis. Hierarchical generalized linear models were constructed to assess the association of pre-operative diagnostic procedures, presenting signs, and admitting service with time to surgery.RESULTS: Seventy cases met inclusion and exclusion criteria, among which 12 were admitted to the medical service and 58 to the surgical service. Mean ± SD time to surgery was 39.3 ± 43 h, with 87% of operations performed within 72 h of hospital arrival. In the adjusted models, longer time to surgery was associated with number of diagnostic studies and endoscopic retrograde cholangio-pancreatography (ERCP, P = 0.01) as well with admission to medical service without adjustment for ERCP (P < 0.05). Patients undergoing both magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) scans experienced the longest waits for surgery. Patients admitted to the surgical versus medical service underwent surgery earlier (30.4 ± 34.9 vs 82.7 ± 55.1 h, P < 0.01), had less post-operative complications (12% vs 58%, P < 0.01), and shorter length of stay (4.3 ± 3.4 vs 8.1 ± 5.2 d, P < 0.01).CONCLUSION: Admission to the medical service and performance of numerous diagnostic procedures, ERCP, or MRCP combined with CT scan were associated with longer time to surgery. Expeditious performance of ERCP and MRCP and admission of medically stable patients with suspected cholecystitis to the surgical service to speed up time to surgery should be considered.

Safety advantage of endocut mode over endoscopic sphincterotomy for choledocholithiasis

AIM： To evaluate whether an automatically controlled cut system （endocut mode） could reduce the complication rate of endoscopic sphincterotomy （EST） and serum hyperamylasemia after EST compared to the conventional blended cut mode. METHODS： From January 2001 to October 2003, 134 patients with choledocholithiasis were assigned to either endocut mode group or conventional blended cut mode group at the time of sphincterotomy. The two groups were retrospectively compared for the complications after EST and serum amylase level before and 24 h after the procedure. RESULTS： Of the 134 patients treated, 79 were assigned to conventional blended cut mode group and 55 to endocut mode group. There was no significant difference in age, sex, and serum amylase level before EST between the two groups. Complications were found in 5 patients of the endocut mode group （9%）： hyperamylasemia （5 times higher than normal） in 4 and moderate pancreatitis in 1. Complications were found in 13 patients of the conventional blended cut mode group （16%）： hyperamylasemia in 12 and moderate pancreatitis in 1. Serum amylase levels were elevated in both groups 24 h after EST （P〈0.02）. The average serum amylase level 24 h after EST in the conventional blended cut mode group was significantly higher than that in the endocut mode group （P〈 0.05）. CONCLUSION： Endocut mode offers a safety advantage over conventional blended cut mode for pancreatitis after EST by reducing hyperamylasemia.

Double-balloon-enteroscopy-based endoscopic retrograde cholangiopancreatography in post-surgical patients

AIM: To evaluate double balloon enteroscopy (DBE) in post-surgical patients to perform endoscopic retrograde cholangiopancreatography (ERCP) and interventions. METHODS: In 37 post-surgical patients, a stepwise approach was performed to reach normal papilla or enteral anastomoses of the biliary tract/pancreas. When conventional endoscopy failed, DBE-based ERCP was performed and standard parameters for DBE, ERCP and interventions were recorded. RESULTS: Push-enteroscopy (overall, 16 procedures) reached enteral anastomoses only in six out of 37 post-surgical patients (16.2%). DBE achieved a high rate of luminal access to the biliary tract in 23 of the remaining 31 patients (74.1%) and to the pancreatic duct (three patients). Among all DBE-based ERCPs (86 procedures), 21/23 patients (91.3%) were successfully treated. Interventions included ostium incision or papillotomy in 6/23 (26%) and 7/23 patients (30.4%), respectively. Biliary endoprosthesis insertion and regular exchange was achieved in 17/23 (73.9%) and 7/23 patients (30.4%), respectively. Furthermore, bile duct stone extraction as well as ostium and papillary dilation were performed in 5/23 (21.7%) and 3/23 patients (13.0%), respectively. Complications during DBE-based procedures were bleeding (1.1%), perforation (2.3%) and pancreatitis (2.3%), and minor complications occurred in up to 19.1%. CONCLUSION: The appropriate use of DBE yields a high rate of luminal access to papilla or enteral anastomoses in more than two-thirds of post-surgical patients, allowing important successful endoscopic therapeutic interventions.

ASSESSING THE RESECTABILITY OF PANCREATIC DUCTAL ADENOCARCINOMA:COMPARISION OF DUAL- PHASE HELICAL CT ARTERIAL PORTOGRAPHY WITH CONVENTIONAL ANGIOGRAPHY

To evaluate the respective value of dual- phase helical CT arterial portography (CTAP) and conventional angiography in preoperative predicting resectability of pancreatic ductal adenocarcinoma. Subjects and methods. Tumor resectability was prospectively evaluated in 54 patients with pathologically proven pancreatic ductal adenocarcinoma who later underwent surgery. Both dual- phase helical CT scanning and selective angiography were obtained in each patient preoperatively. For optimal enhancement of pancreas and major peripancreatic vessels, two catheters connected to an automatic injector via a Y- shaped tube were placed after selective angiography,one in celiac trunk, the other in superior mesenteric artery. Then the patient underwent dual- phase helical CTAP of pancreas and liver. The criteria of irresectability for CTAP include: tumor diameter≥ 5 cm,extrapancreatic invasion, distant metastases and vascular involvement(occlusion, stenosis or semicircular encasement of superior mesenteric artery, hepatic artery, splenic artery, celiac axis; portal vein, superior mesenteric vein or splenic vein). The results of both modalities were correlated with findings from surgery or pathology. Results. Thirty- eight of 54 patients had nonresectable disease. In prediction the irresectability, sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy were 94.7％ ,100％ ,100％ ,88.9％ ,96.3％ respectively for helical CTAP and 63.2％ ,93.8％ ,96.0％ ,51.7％ ,72.2％ respectively for selective angiography. In assessing vascular involvements, dual- phase helical CTAP was also superior to selective angiography. Conclusion. Dual- phase helical CTAP is superior to angiography in assessing resectability of pancreatic ductal adenocarcinoma. The combination of the two modalities may further improve overall accuracy of assessment.

Modification of end-loop ileostomy for the treatment of ischemic or radiation enteritis

AIM: To evaluate a new technique of temporary ileal anastomotic stoma, following small bowel resection, in patients where the anastomosis is anticipated to have borderline margins with dubious viability. METHODS: Five patients underwent enterectomy and partially anastomosed end-loop ileostomy at the University Hospital of Larissa between 2000 and 2006. Enterectomy was performed because of conditions such as mesenteric vascular occlusive disease, radiation entritis and small bowel injury. RESULTS: Postoperatively, none of the patients developed any stoma-related or anastomotic complications. There were no major complications. All patients were discharged between the 8th and 15th day after the procedure, and the stoma was closed 3 wk to 4 wk later. CONCLUSION: We believe that our proposed modification of end-loop ileostomy is a simple, quick and safe technique with minimal stoma-related morbidity, and with simple and safe reversion. This technique can be considered as a useful option in the treatment of ischemic or radiation-induced enteritis, and in the management of severe intestinal trauma.

Is intra-operative cholangiography necessary during laparoscopic cholecystectomy? A multicentre rural experience from a developing world country

AIM: To evaluate the feasibility and safety of performing laparoscopic cholecystectomy (LC) in nonteaching rural hospitals of a developing country without intra-operative cholangiography (IOC). To evaluate the possibility of reduction of costs and hospital stay for patients undergoing LC.METHODS: A prospective analysis of patients with symptomatic benign diseases of gall bladder undergoing LC in three non-teaching rural hospitals of Kashmir Valley from Jan 2001 to Jan 2007. The cohort represented a sample of patients requiring LC, aged 13 to 78 (mean 47.2) years. Main outcome parameters included mortality, complications, re-operation, conversion to open procedure without resorting to IOC, reduction in costs borne by the hospital, and the duration of hospital stay.RESULTS: Twelve hundred and sixty-seven patients (976 females/291 males) underwent laparoscopic cholecystectomy. Twenty-three cases were converted to open procedures; 12 patients developed port site infection, nobody died because of the procedure. One patient had common bile duct (CBD) injury, 4 patients had biliary leak, and 4 patients had subcutaneous emphysema. One cholecystohepatic duct was detected and managed intraoperatively, 1 patient had retained CBD stones, while 1 patient had retained cystic duct stones. Incidental gallbladder malignancy was detected in 2 cases. No long-term complications were detected up to now.CONCLUSION: LC can be performed safely even in non-teaching rural hospitals of a developing country provided proper equipment is available and the surgeons and other team members are well trained in the procedure. It is stressed that IOC is not essential to prevent biliary tract injuries and missed CBD stones. The costs to the patient and the hospital can be minimized by using reusable instruments, intracorporeal sutures, and condoms instead of titanium clips and endobags.

Effect of an escape vent in accordion-shaped traps on the catch and size of Asian paddle crabs Charybdis japonica in an artificial reef area

Accordion-shaped traps are widely used in China to catch the Asian paddle crab C harybdis japonica but traps of conventional design often catch juvenile crabs. A new type of accordion-shaped trap with an escape vent(L×W=4.3 cm×3.0 cm) was designed and a comparative study between the newly designed and conventional traps was performed in the artifi cial reef area of Zhuwang, Laizhou Bay, China from June to August 2012. The mean catch per unit effort(CPUE) of undersized crabs was signifi cantly lower in the vented traps than in the conventional traps(paired t-test, n =30, P <0.001), while the CPUE of marketable crabs was signifi cantly higher in the vented traps(paired t-test, n =30, P <0.001). The mean size of crabs(carapace length) caught in the vented traps was signifi cantly larger than in conventional traps(paired t-test, n =29, P <0.001). The ratio of undersized crabs was 35.05%±2.57% in conventional traps and 12.53%±0.69% in vented traps(signifi cantly lower, paired t-test, n =29, P <0.001). Therefore, a 4.3 cm×3.0 cm escape vent was considered appropriate for C. japonica fi shing in the artifi cial reef area. This fi nding will assist the development of more sustainable and effi cient crab fi shing methods using accordion-shaped traps.

Cholangiocarcinoma:A 7-year experience at a single center in Greece

AIM： To evaluate survival rate and clinical outcome of cholangiocarcinoma. METHODS： The medical records of 34 patients with cholangiocarcinoma, seen at a single hospital between the years 1999-2006, were retrospectively reviewed. RESULTS： Thirty-four patients with a median age of 75 years were included. Seventeen （50%） had painless jaundice at presentation. Sixteen （47.1%） were perihilar, 15 （44.1%） extrahepatic and three （8.8%） intrahepatic. Endoscopic retrograde cholangiography （ERCP） and/or magnetic resonance cholangiography （MRCP） were used for the diagnosis. Pathologic confirmation was obtained in seven and positive cytological examination in three. Thirteen patients had co-morbidities （38.2%）. Four cases were managed with complete surgical resection. All the rest of the cases （30） were characterized as non-resectable due to advanced stage of the disease. Palliative biliary drainage was performed in 26/30 （86.6%）. The mean follow-up was 32 mo （95% CI, 20-43 too）. Overall median survival was 8.7 mo （95% CI, 2-16 mo）. The probability of 1-year, 2-year and 3-year survival was 46%, 20% and 7%, respectively. The survival was slightly longer in patients who underwent resection compared to those who did not, but this difference failed to reach statistical significance. Patients who underwent biliary drainage had an advantage in survival compared to those who did not （probability of survival 53% vs 0% at 1 year, respectively, P = 0.038）. CONCLUSION： Patients with cholangiocarcinoma were usually elderly with co-morbidities and/oradvanced disease at presentation. Even though a slight amelioration in survival with palliative biliary drainage was observed, patients had dismal outcome without resection of the tumor.

Analyzing the Value Chains of China＇s Knock-off Handset industry

Establishing a two-sided market （specialized market） is an effective way to build a national value chain （NVC）. The Chinese knock-off wireless handset industry has succeeded in building a miniature version of an NVC based on the Huaqiangbei Market, a typical specialized market. ＂Ihis paper begins b）, analyzing the differences in the industrial chains of knock-off and traditional wireless handsets and concludes that due to lacking after-sales service, the value chain of knock-off wireless handsets is consumer-driven, with a focus on manufacturing and marketing. Analysis of the knock-off wireless handset-based NVC reveals that multi-level demands, a maturing industry and adaptive innovation are three pre-conditions for Chinese manufacturing to build an NVC in a two-sided market. Given the uneven scale and techniques among knock-off handset makers, their addiction to the low-end market and imperfect value chains constructed using the ＂knockoff pattern＂ this paper proposes that China can break these bottlenecks by letting the specialized and unilateral markets develop closer to each other and by providing governmental guidance in the specialized market.

Experimental Results Regarding an Anthropomorphic Original Gripper with Two-Finger Tests during Grasping Objects with Varied Shapes

The paper presents theoretical and experimental results on an original anthropomorphic gripping concept. Compared to the existing anthropomorphic grippers, this gripper is very simple, yet it has the advantage of high performance in terms of gripping possibilities and a very low manufacturing cost. Source of inspiration was the human hand, which is able to catch objects by only using two fingers. The analyzed anthropomorphic gripper has two fingers, with two phalanxes each, and is based on a new mechanism with articulated bars. The kinematic analysis performed on the gripping mechanism reveals the optimal displacement in the translational coupling, which was experimentally validated. The gripping possibilities were increased by attaching clamping jaws to each phalanx. The clamping jaws have been attached by means of spherical couplings, thus offering the possibility to catch objects with any type of surface. By carrying out gripping tests with different objects, we underline the importance of a safe use of the two-fingered anthropomorphic grippers in different applications. Due to the innovative mechanical structure, the gripper can insure the minimal gripping conditions, whilst the complexity of the objects that can be gripped make it suitable for the use in robots.

APPLICATION OF MAGNETIC RESONANCE ANGIOGRAPHY IN PORTAL HYPERTENSIVE SURGERY

Objective To compare magnetic resonance angiography （MRA） with traditional angiography and doppler ultrasonography （DUS） in the assessment of portal venous anatomy and its hemodynamics. Methods Three dimensional dynamic contrast-enhanced （ 3 D-DCE） MRA and two dimensional phase-contrast （2D-PC） MR were used for the study of portal venous system in the patients with portal hypertension and those without liver cirrhosis. The comparison of the portal blood flow （PBF） measured with 2D-PC MR and DUS was made. Results The portal vein, splenic vein, superior mesenteric vein, cephalic collateral veins and anastomotic stoma of surgical shunting were clearly displayed in 3D-DCE MRA. There was no significant difference between PBF measured with 2D-PC MR and DUS. Conclusion The results of present study indicate that the anatomical imaging of the portal venous system can be dearly revealed in MRA and the PBF can be accurately measured with 2D-PC MR. It is believed that MRA is a useful tool in the management of the patients with portal hypertension.
