ABSTRACT
Radiotherapy is still a major part of the program about treating various head and neck cancers. While improving the survival rate of head and neck cancer patients, radiotherapy can cause the decline of learning, memory, orientation and other functions, seriously, even lead to dementia, namely radiation induced cognitive dysfunction (RICD), which has become a critical factor affecting the quality of life for patients. Because of occult onset and unclear pathogenesis, so far there is few effective preventive and therapeutic tools for RICD. In this paper, the latest research progress on the pathogenesis and treatments of RICD is summarized.
ABSTRACT
Objective@#To investigate the prognostic factors of hyperamylasemia following pancreaticoduodenectomy (PD) .@*Methods@#Clinical data of 359 patients were collected prospectively who underwent PD by the same group at Changhai Hospital of Navy Medical University from January 2017 to June 2018.There were 212 males and 147 females.The median age was 63 years old (range: 23 to 82 years old) .According to whether the patient′s serum amylase was greater than 120 U/L at 0 or 1 day after surgery,the patients were divided into hyperamylasemia group and non-hyperamylasemia group. Univariate analysis and multivariate analysis were used to find out the prognostic factors of hyperamylasemia after PD.@*Results@#Of the 359 patients, 238 cases (66.3%) developed hyperamylasemia.The incidence rate of clinically related pancreatic fistula (15.1% vs.2.5%, P<0.01) , grade B/C post pancreatectomy hemorrhage (8.8% vs. 2.5%, P<0.01) , and surgical site infection (9.2% vs. 3.3%, P=0.04) was significantly higher in the hyperamylasemia group.The severity of complications (CD grade≥Ⅲ: 11.3% vs.4.1%, P=0.023) and postoperative hospital stay (11 days vs. 9 days, P=0.001) were higher in the hyperamylasemia group.In the multivariate analysis, the main pancreatic duct diameter (MPD) ≤3 mm (OR=4.469, 95% CI: 2.563-7.793, P<0.01) , pathological type of disease (pancreatic cancer or pancreatitis) (OR=0.230, 95% CI: 0.122-0.436, P<0.01) and soft texture of pancreas (OR=3.297, 95%CI: 1.930-5.635, P<0.01) were independent prognostic factors for hyperamylasemia.@*Conclusions@#Post-PD hyperamylasemia increased the incidence and severity of postoperative complications after PD.MPD≤3 mm, soft texture of pancreas and pathological type of disease were independent prognostic factors of hyperamylasemia.
ABSTRACT
Objective To observe and analyze clinical characteristics of diabetes patients suffering from pancreatic cancer . Methods We recruited 107 cases of pancreatic cancer(66 without diabetes and 41 with diabetes) and 100 diabetes patients without pancreatic pancreas as control .Patients′ demographic information ,degree of tumor differentiation ,serum markers etc .were com‐pared in order to find out the relevant clinical features of diabetes patients suffering from pancreatic cancer .Results (1)Patients with pancreatic cancer mostly were middle‐aged males .55 .1% of them suffering from dysglycemia ,18(16 .8% ) and 41(38 .3% ) of whom had impaired fasting glucose and diabetes ,respectively .(2)Compared with their without diabetes counterparts ,pancreatic cancer with diabetes were more prone to be asymptomatic and weight loss(P< 0 .05) .(3)Compared with their without diabetes counterparts ,pancreatic cancer with diabetes had significantly higher levels of fasting blood glucose(FBG) andγ‐glutamyltranspep‐tidase(γ‐GT)(P<0 .05) .(4)When compared with diabetes control ,pancreatic cancer with diabetes were older and shorter duration and lower body mass index(BMI)(P<0 .05) .They were more prone to weight loss(P<0 .05) .Moreover ,serum CA19‐9 and CEA levels in them were significantly higher than those in the diabetes control(P<0 .05) .Conclusion Older age ,shorter duration ,low BMI are all risk factors for diabetes patients to develop pancreatic cancer .Being asymptomatic and weight loss are their clinical characteristics .CA19‐9 and CEA are both sensitive serum markers to detect pancreatic cancer patients with diabetes .

ABSTRACT
Objectives To investigate the role of lymphangiogenesis in the perineural micrometastasis of pancreatic adenocarcinoma. Methods The clinical data of 30 pancreatic adenocarcinoma patients who were admitted from Sep. 2005 to Oct. 2006 for extended radical surgery were collected. The samples including pancreatic cancer, adjacent tissue, lower bile duct, pancreatic tail, the structure surrounding the SMA (peripancreatic nerve plexus) and lymph nodes were collected during operation. They were subjected to conventional pathological examination. The lymphatic capillaries weredetected by double immunohistochemical staining and the lymphatic vessel density ( LVD) was measured. Results Intra-pancreatic and/or peripancreatic neural invasion was observed in 25 patients (83. 3% ) , of which 20 were found to have both the peri-pancreatic and intra-pancreatic neural invasion. The other 5 only had the intrapancreatic neural fiber invasion and there was no single patient with peri-pancreatic neural fiber invasion only. Peri-neural invasion was not significantly associated with patients' age, gender, lymph node metastasis, tumor size and the location (P > 0.05) , but was obviously associated with JPS clinical staging ( P < 0. 05 ). The mean intratumoral LVD was (4.2 ±3.4) per field, which was significantly lower than (11.3 ±6.9) per field of adjacent tissue and (10.8 ±4.4)per field of normal pancreatic tissue(P<0.01). The mean intratumoral LVD between adjacent tissue and normal pancreatic tissue was not statistically different. Lymphatic vessel invasion was observed in non-malignant tissues in 18 patients, and there was a distribution correlation between lymphatic vessel invasion and extra-pancreatic neural plexus invasion (P<0.05). Conclusions The incidence of peri-neural invasion was high, peri-neural invasion was associated with JPS clinical staging and lymphatic vessel invasion, which suggested the possibility of the cancer spreading by peritumoral lymphangiogenesis route into the peri-SMA neural plexuses.

ABSTRACT
<p><b>OBJECTIVE</b>To retrospectively compare combined endovascular intervension with traditional bypass operation for the treatment of Budd-Chiari syndrome (BCS).</p><p><b>METHODS</b>From July 1989 to June 2001, 49 patients undergoing surgery for BCS were studied. 32 operations were performed by traditional bypass (from superior mesenteric vein or inferior vena cava to right auricle), and 17 by combined endovascular operation.</p><p><b>RESULTS</b>The data demonstrated a high incidence of perioperative complications, longer hospital stay, and expensive cost in the former group than in the latter group (P < 0.01). The mid-term effects were significantly better in the latter than in the former (P < 0.05). Severe complications occurred in the bypass group included hepatoencephalopathy, obtinacy ascites, cardiac dysfunction, and embolization of vascular grafts.</p><p><b>CONCLUSIONS</b>Combined endovascular intervention and shunting are the treatment of choice for BCS, with different combination according to its clinical type. This approach is simple, safe, effective, and economic.</p>

ObjectiveTo evaluate the effect of interventional endovascular treatment for Budd-Chiari syndrome. MethodsIn 15 cases of Budd-Chiari syndrome, repatency of the obstructive inferior vena cava was successfully carried out by percutaneous transluminal balloon dilatation first, and then self-expanding stents was placed in 13 patients. In 4 patients with complete obliteration of the hepatic veins, "H" graft mesocaval shunts were performed one week later. ResultsMild heart dysfunction occurred in one case after endovascular intervention.Patients were followed-up from 2 to 42 months postoperatively. Except one re-stenosis distal to the stent, no stent migration and thromboembolization in shunting grafts occurred. The symptoms of portosystemic hypertension were relieved significantly. Conclusions Budd-Chiari syndrome could be effectively treated by interventional endovascular procedures.
ABSTRACT
The effect of bilateral carotid occlusion for 60 min and reperfusion for 30 min on levels of water and lipid peroxides (LPO) and activities of Na+, K+ -ATPase and superoxide dismutase (SOD) in the forebrain was studied in gerbils (Meriones unguiculatus). Luring occlusion, increased water content and decreased activities of Na+, K+-ATPase and SOD were observed. After reperfusion, the activities of Na+, K+ -ATPase and SOD continued decreasing, but LPO elevated apparently. These results support a hypothesis that the free radicals may contribute to the damage of ischemic brain tissue. Pretreatment of gerbils with allopurinol offered protection to cerebral Na+, K+ -ATPase and SOD subsequent to secondary ischemia.
