Purpose:To evaluate the effect of oxaliplation (L-OHP)+flurouracil/calcium folinate(5-FU/CF) in combination with concurrent radiotherapy for advanced rectal cancer and to find a more effective way of giving them.Meth- ods:Chemotherapy:L-OHP 130 mg/m~2,iv infusion for 2 hours D_1 combined with calcium folinate 200 mg/m~2 for 2 h ours followed by 5-fluorouracil 300 mg/m~2 for 4h D_1～D_5,repeated every 3 weeks.Radiotherapy:The whole pelvic irradiation DT 50～60Gy/25～30/F(5～6 weeks).Results:30 advanced rectal cancer patients entered the study.One patient reached complete response(CR),15 partial response,13 stable disease,and 1 with progression after treatment,The overall re- sponse rate(CR+PR) was 53.3%,the 1-year survival rate was 70% (21/30).The main adverse acute effects were gas- trointestinitis,anemia,neuro-sensory toxicity and irradiation rectitis,bone marrow suppression was mild.Conclusions: This approach of therapy could improve the therapeutic effect on advanced rectal cancer.

Objective To investigate risk factors related to postoperative death of patients with rectosigmoid junction tumor perforation.Methods The clinical data of 76 cases with rectosigmoid junction tumor perforation confirmed by laparotomy from January 2000 to October 2015 were collected.Results Of the 76 cases,17 patients died postoperatively,the mortality rate was 22％,the single factor analysis showed that age(x2 =4.649,P =0.031),duration of abdominal pain(x2 =8.218,P =0.016),severe heart and lung diseases(x2 =11.996,P =0.007),circulatory and renal function(x2 =10.360,P =0.016),serum albumin(x2 =7.252,P =0.027),white blood cell count(x2 =7.633,P =0.022),Perforation diameter (x2 =9.770,P =0.008),Geroge grade of intraperitoneal contamination (x2 =10.086,P =0.006) were related to postoperative death (P ＜ 0.05).Multivariate analysis showed that complicating severe heart and lung diseases,preexisted circulatory and renal dysfunction,white blood cell count ＜ 4 × 109/L,size ＞ 3 cm,intraperitoneal contamination larger than one quadrant were independent risk factors for postoperative death.Conclusion Risk factors related to postoperative death of rectosigmoid junction tumor perforation were preoperative important organ dysfunction and intraperitoneal infection.

The influences of the calmodulin antagonist chlorpromazine (CPZ), and calcium chanmel blocker nimodipine (NLMO) and their combination on cadmium (Cd) poisoning of mice were studied.A series of biochemical parameters including urinary enzyme activities, blood and urine Cd levels, metallothionein (MT) contents in liver and kidney, hepatic ultrastructure and Ca2+ -Mg2- AT Pase activitv in erythrocyte membrane were determined. Animal models for Cd poisoning were established by peritoneal injection of 1/5 LD50 CdCl2. The experimental groups were protected by administration of CPZ, NIMO and CPZ and NIMO in combination I h before the injection of CdCl2. Five days later, samples were collected for analysis. The data showed that CPZ could protect kidney tissue against Cd-induced damage, as the urinary y-glutamyl-traspeptidase (γ-GT) and N-acetyl-β-D-glucosaminidase (NAG) activities were reduced significantly. There was neither evidence of the protective effect of NIMO on kidney tissue nor an indication of a synergistic effecf of CPZ and NIMO.Both CPZ and NIMO showed a considerable protective effect against the decrease in Ca2+ -Mg2+ AT-Pase activity, and a synergistic action was observed. Cd content in blood was reduced significantly by CPZ or the combination of CPZ and NIMO, but elevated by NIMO. Both CPZ and NIMO considerably increased MT contents in livers and kidneys and ameliorated damaged to the hepatic ultrastructures caused by Cd. The results indicated that these inhibitors could protect mice against the toxic effects of Cd in liver and kidney tissues, while CPZ was more efficient than NIMO. The combination of CPZ and NIMO excrted a synergistic action. The protective action of these two drugs might be relevent to the function of MT.

OBJECTIVETo observe the effect of general anaesthesia with combination of acupuncture [conducted with Han's acupoint nerve stimulator (HANS) applied] and enflurane in radical operation of laryngocarcinoma (LC).

METHODSSixty patients with LC of grade I - II , classified according to the standard of American Society of Anesthesiologists (ASA), were assigned by randomizing number table to the control group and the tested group, 30 patients in each group. The control group received anaesthesia with enflurane alone for inducing and maintaining; the tested group was anaesthetized with enflurane like that given to the control group but also received additionally needling stimulation conducted by HANS. The dosage of enflurane used, the minimum effective concentration of enflurane in alveolar air (MACEnf) and the changes of heart rate (HR) as well as blood pressure (BP) in patients at different time points in the operational process were observed.

RESULTSAs compared with those in the control group, in the tested group, both the MACEnf and the dosage of enflurane were reduced, with the difference between the two groups significant (P<0. 01). The changes of HR and BP among different time points in the tested group were slight, and as compared with those in the control group at the corresponding time points, the difference was significant ( P <0. 05 or P<0.01).

CONCLUSIONGeneral anaesthesia with combination of enflurane and needling conducted by HANS applied in radical operation of LC has definite effect with less complication. Needling could be cooperated with narcotics, and so it could be taken as an auxiliary measure of anaesthesia for radical operation of LC.

OBJECTIVETo observe the clinical effect of Yufeng Capsule (YFC), a Chinese herbal preparation with function of clearing Heat-toxin in treating premonitory symptoms of apoplexy in middle and old aged patients.

METHODSOne hundred and fourteen patients with premonitory symptoms of apoplexy were treated with YFC and compared with 57 patients treated with Venoruton for control. The changes of clinical symptoms, anti-oxidation capability, blood lipid, blood sugar and hemorrheological parameters were observed.

RESULTS(1) The therapeutic effect in the YFC group was cured in 42 cases (36.84%), markedly effective in 38 (33.33%), effective in 28 (24.58%) and the total effective rate was 94.74%, while in the control group, the corresponding numbers were 9 (15.79%), 8(14.04%), 20(35.09%) and 64.91% respectively, the difference between the two groups in cure rate, markedly effective rate and total effective rate was significant (P < 0.05); (2) The whole blood viscosity, plasma viscosity, hemagglutination index and red blood cell deformity index in the YFC group were significantly improved after treatment (P < 0.01) and the improvement was better than those in the control group (P < 0.05 or P < 0.01); (3) Levels of serum malonyldialdehyde (MDA), superoxide dismutase (SOD), blood lipids and glucose were markedly improved in the YFC group (P < 0.05) after treatment, and showed a significant difference to those in the control group (P < 0.05).

CONCLUSIONYFC has obvious effect in treating premonitory symptoms of apoplexy patients, it could markedly improve the hemorrheologic parameters, regulate blood lipids and blood glucose metabolism, and strengthen the anti-oxidation capability of patients.

Objective To analyze the CT features of renal cell carcinoma,so as to improve the diagnostic accuracy of renal cell carcinoma.Methods Three hundred cases of renal cell carcinoma proved by pathology were examined by means of CT.There were 214 male and 86 female in this group.Their age ranged from 9 to 81 years,with a mean of 53.7 years.Their CT features were retrospectively reviewed. Results The masses were 1.5—16.0 cm(mean,4.8 cm)in greatest dimension,125 masses on left kidney and 175 masses on right kidney.According to WHO histological classification of tumours of the kidney in 2004,there were 238 cases of clear cell renal cell carcinoma,6 cases of multilocular clear cell renal cell carcinomas,23 cases of papillary renal cell carcinoma,14 cases of chromophobe renal cell carcinoma and 19 cases of renal cell carcinoma,unclassified.The above subtype of renal cell carcinoma demonstrated characteristic features.Clear cell renal cell carcinoma exhibited inhomogenous(due to hemorrhage,necrosis or cystic degeneration)and hypervaseular.Multilocular clear cell renal cell carcinoma presented as a multilocular cystic mass lacking an,expansile nodule,and with regular thin cyst wall and septa.Papillary renal cell carcinoma exhibited inhomogenous and hypovascular.Chromophobe renal cell carcinoma was relatively homogenous and hypovascular.Renal cell carcinoma,unclassified showed inhomogenous and hypervascular,and was more invading growth compared to clear cell renal cell carcinoma. Conclusion Common subtype of renal cell carcinoma demonstrated characteristic features in CT and it is helpful for differentiation.

Objective To transplant the umbilical cord mesenchymal stem cells(UCMSCs) derived from human umbilical cord into cisterna magna of hypoxic-ischemic encephalopathy(HIE) rat model,and to observe their survival,proliferation and differentiation in the rat brain.Methods UCMSCs were isolated from human umbilical cord of babies delivered after full-term normal cesarean section,and labeled by bromodeoxyuridine(BrdU).Pregnant rats were randomly divided into experimental group(n=6) and control group(n=1).HIE models were built by ligating both sides of the uterine arteries of full-pregnant rats(21 days) in experimental group rats for 15 minutes.The neonatal rats in experimental group were divided into stem cells group(n=24) and PBS group(n=19) at random.The labeled UCMSCs were injected into cisterna magna of the rats in stem cells group,while PBS was injected into the rats of PBS group.In 1,2,3 and 4 weeks after transplantation,the brain tissue section slides were immunohistochemically stained with antibodies against BrdU,Nestin,neuron specific enolase(NSE) and glial fibrillary acidic protein(GFAP),and thionin.Control group with normal delivery was tested as concurrent control.Results At 1 week after transplantation,BrdU,Nestin,NSE and GFAP positive cells were found in the hippocampal dentate gyrus of the rats in stem cells group rats.The number of BrdU-positive and Nestin-positive cells increased(Pa0.05).The NSE-positive and GFAP-positive cells gradually increased from 1-4 weeks post transplantation and comparisons between groups had statistical significance(Pa

AIM: To test the expression of erythropoietin (Epo) and its receptor EpoR in normal and neovascularized murine corneas induced by alkali burns, and to investigate whether Epo/EpoR is involved in the process of corneal angiogenesis.METHODS: The expression of Epo/EpoR was tested in normal and neovascularized murine corneas induced by alkali burns through immunohistochemistry of corneal frozen sections. Epo cloning, expression, and purification were carried out. Then Epo protein (6μL, 1μg) and control (6μ L of vector control or saline) were injected into the corneal stroma respectively, and the corneas were checked at the 14th day after injection to see whether corneal neovascuarization occurred.RESULTS: Epo/EpoR was expressed in epithelial cells, endothelial cells and stromal cells in normal and neovascularized corneas induced by alkaline burns, and also expressed strongly in neovascularized cornea. They were expressed at the same time in stromal inflammatory cells and new vessels. Corneal neovascularization was induced by Epo intrastromal injection in 5 out of 6 eyes ,but no new vessels were observed in all controls (n = 6) at day 14 after vector control or saline intrastromal injection in normal corneas.CONCLUSION: This paper first reported the expression of Epo and its receptor in normal and neovascularized cornea. Injection of Epo into the corneal stroma may induce the corneal neovascularization. Epo/EpoR is associated with the formation of corneal neovascularization.
