Objective To study the relationship between coronary arteriographic and fluorescence fundus angiographic characteristics in type 2 diabetic patients with coronary heart disease.Methods The study was carried out by the analysis of the data from coronary arteriography and fluorescence fundus angiography in 203 type 2 diabetic patients with coronary heart disease in different groups divided according to age or total cholesterol level. Logisitic regression analysis was applied to explore various risk factors to angiographic characteristics.Results With advancing age,there were more involvement of 3 coronary vessels or the left main branch along with stageⅢretinopathy,but less single vessel diseases in the coronary arteries and less stageⅠretinopathy.The difference in coronary angiographic and fluorescence fundus angiographic characteristics between groups with different total cholesterol levels was not significant.Logistic regression analysis suggested that coronary artery diaease was related to age,sex and blood glucose and triglyceride levels while diabetic retinopathy was related to blood glucose level and age.Conclusion There is great difference in coronary arteriography and fluorescence fundus angiography among different age groups.Aging may aggravate the lesions both in the coronary arteries and fundal vessels in type 2 diabetic patients with coronary heart diseease.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.

METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.

RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.

CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

Objective To compare the survival outcomes between operative versus non-operative treatment of advanced intrahepatic cholangiocarcinoma.Methods This is a retrospective study.The data from 122 patients with intrahepatic cholangiocarcinoma treated at the Hunan People's Hospital,the Hepatobiliary Hospital and the Oncology Department from January 2012 to October 2017 were retrospective studied.87 patients who underwent radical surgery (anatomical hepatectomy + regional lymph node dissection) formed the operation group;35 patients who were treated with chemotherapy and/or radiotherapy and/or biological targeted therapy formed the non-operative group.The general characteristics of the two groups including age,sex,ALT,AST,CA19-9,liver function,Child's classification,AJCC staging,tumor number,vascular (hepatic artery,portal vein) invasion and regional lymph node metastasis rates were compared.The overall survival of the two groups was compared.Results There were no significant differences in age,sex,ALT,AST,CA19-9,liver function,Child's classification,AJCC staging,tumor number,vascular (hepatic artery,portal vein) invasion and regional lymph node metastasis rates (P＞0.05).The overall survival of the operation group was significantly longer than that of the non-operative group (P＜0.05).The mean overall survival for the 2 groups of patients were 32 months and 15 months respectively.The 1-year survival rates were 74.8％ and 58.7％,and the 3 year survival rates were 42.4％ and 6.5％,respectively.The 5 years survival rates were 12.3％ and 0,respectively.Conclusion Operative treatment resulted in better median survival,as well as 1-,3-and 5-year survival rates than non-operative treatment for patients with advanced intrahepatic cholangiocarcinoma.

Objective To assess the clinical application of contrast-enhanced MR angiography using three-dimensional(3D)time-resolved imaging of contrast kinetics(CE-MRA 3D-TRICKS).Methods TRICKS is a high temporal resolution(2—6s)MR angiographic technique using a short TR(2.8— 4.0 ms)and TE(0.9—1.3 ms),partial echo sampling and the central part of the k-space being updated more frequently than the peripheral part of the k-space.Pre-contrast mask 3D images are first acquired and 15--20 sequential 3D images following bolus injection of Gd-DTPA are then acquired.Results Thirty patients underwent contrast-enhanced MR angiography using TRICKS.Twelve vertebral arteries were well displayed on TRICKS.Seven of them showed normal,bilateral vertebral artery stenosis was shown in 1 case, and unilateral vertebral artery stenosis was shown in 4 wth aecompaning ipsilateral carotid artery bifurcation stenosis in one case.Bilateral renal artery showed normal in 4 cases,and the artery in transplanted kidney showed normal in one case and stenosis in another case.The cerebral artery showed normal in 2 cases, sagittal sinus thrombosis was detected in one case and intracranial arteriovenous malformation in one case. Pulmonary artery displayed normal in 3 cases,pulmonary artery thrombosis was seen in one case and pulmonary sequestration's abnormal feeding artery and draining vein was revealed in one case.The feeding artery in left lower limb fibrolipoma was showed in one case.The radial-ulnar artery artificial fistula stenosis was seen in one case,and left antebrachium hemangioma was showed in one case.Conclusion TRICKS can clearly delineate the whole body vascular system and can reveal any vascular abnormality.It is convenient and with high successful rate,which make it the first method of choice in displaying vascular abnormality.

PURPOSE: CO₂ leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasis after laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis between B-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). MATERIALS AND METHODS: Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC. Clinical efficacy was assessed from the objective remission rate (ORR), the Karnofsky Performance Status (KPS) score, and overall survival. The incidence of port-site metastasis was compared between the two groups. RESULTS: Patients in the B-ultrasound (n=32) and laparoscopy (n=30) groups were comparable in terms of age, sex, primary disease type, volume of ascites, and free cancer cell (FCC)-positive ascites. After HIPPC, there were no significant differences between the B-ultrasound and laparoscopy groups in the KPS score change, ORR, and median survival time. The incidence of port-site metastasis after HIPPC was not significantly different between the B-ultrasound (3 of 32, 9.36%) and laparoscopy (3 of 30, 10%) groups, but significantly different among pancreatic, gastric, ovarian, and colorectal cancer (33.33, 15.79, 10.00, and 0.00%, p<0.001). CONCLUSION: The chimney effect may not be the key reason for port-site metastasis after laparoscopy. Other factors may play a role, including the local microenvironment at the trocar site and the delivery of viable FCCs (from the tumor or malignant ascites) to the trauma site during laparoscopic surgery.

A high affinity polyclonal antibody-based enzyme linked immunosorbent assay (ELISA) was developed for the quantification of zeranol in bovine urine. On the basis of urine matrix studies, the optimized dilution factors producing insignificant matrix interference were selected as 1:5 in pretreatment. In the improved ELISA, the linear response range was between 0.02 and 1 microg/ml, and the detection limit was 0.02 microg/ml for the assay. The overall recoveries and the coefficients of variation (CVs) were in the range of 82% to approximately 127% and 3.5% to approximately 8.8%, respectively. Thirty-six bovine urine samples spiked with zeranol (ranging from 0.2 to 10 microg/ml) were detected by the ELISA and liquid chromatography (LC) method, and good correlations were obtained between the two methods (R(2)=0.9643). We conclude that this improved ELISA is suitable tool for a mass zeranol screening and can be an alternative for the conventional LC method for zeranol in bovine urine.

OBJECTIVETo investigate and analyze the variation trends in the pathological composition of thyroid cancer patients treated in Tianjin Cancer Hospital from 1954 to 2009.

METHODSTo retrospectively analyze the incidence and clinical features of different pathological types of thyroid cancers in 4342 patients between different time periods from 1954 to 2009.

RESULTSIn the four main pathological types of thyroid cancers, the component ratio of papillary thyroid cancer in every period was 68.1%, 78.3%, 81.3%, 82.1%, 85.8%, respectively, while the morbidity of patients with papillary thyroid carcinoma concurrent with Hashimoto's thyroiditis was increased, so was the proportion of tumors in diameter < or = 2 cm. The proportion of follicular thyroid carcinoma and anaplastic thyroid carcinoma was decreasing accordingly; however, the proportion of medullary thyroid carcinoma did not change significantly.

CONCLUSIONSThe pathological classification of the thyroid carcinoma patients has significant changes in the 4342 cases treated in our Hospital from 1954 to 2009. The proportion of papillary carcinoma is increased, while that of follicular carcinoma and anaplastic carcinoma is decreased. The reasons might attribute to the improved level of consultations and iodized diet or other factors.
