Objective To investigate the effect of treatment with endostatin combined with siRNA targeting VEGF on rats with collagen-induced arthritis (CIA).Methods Two mg/ml bovinetype Ⅱ collagen was injected into the rat footpad to build up the animal model of CIA.The experimental animal models were treated with endostatin combined with siRNA targeting VEGF 18 days later after immunization and the treatment ended 32 day later.The efficacy was evaluated by the weight,foot and ankle volume of rats.The levels of VEGF in plasma were detected by enzyme-linked immunosorbent assay (ELISA).The VEGF distribution within synovial tissue was detected and examined by immunohistochemical technique.The pathological changes of CIA were evaluated by the pathological changes of the biopsied ankle joints.Student's t test was used to evaluate the experimental data.Results The ELISA test showed that comparing with the model group (17.5±0.3),the endostatin group (15.7±0.3) ng/L and the endostatin combined siRNA targeting VEGF group (14.7±0.5) ng/L showed a significant efficacy in the treatment of CIA in rats (P＜0.05).The endostatin group (135±27) and the endostatin combined siRNA targeting VEGF group (126±71) were different in the number of VEGF in plasma and the VEGF distribution within synovial tissue (P＜0.05),the symptoms of arthritis in these rats were reduced than the model group.Conclusion Endostatin combined siRNA targeting VEGF has good therapeutic effect on rats with CIA.

Objective:To detect the pain status and the pain management of home-based advanced cancer patients, and to investigate the key factors impacting the satisfaction on pain management.Methods:Totally the data of 138 cases from the hospice department in the duration from Jan. 2019 to Jun. 2019 were collected and analyzed by χ2 test with SPSS 23.0. Results:109 cases in 138 cases received analgesics treatment before, 54.13% of these participants expressed satisfaction with the effect of their pain management, and 45.87% showed unsatisfied on their pain management. Cancer clinical stage and PMI (pain management index) were both detected to be the significant factors for satisfaction of pain management ( P<0.05, P=0.029; P<0.01, P=0.001) . Conclusions:Cancer clinical stage and PMI are found to be related to the satisfaction for pain management. The percentage of patients who use opioids increased. while there was still a part of patients suffering from inadequacy of pain management. The pain management for home-based advanced patients needs to be paid more attention by medical staff.

Objective:To analyze the detection of gallbladder polyps among shift nurses in Shengjing Hospital of China Medical University in physical examination and its related influencing factors, so as to provide scientific basis for shift nurses to prevent gallbladder polyps.Methods:A total of 1 119 shift nurses who had physical examination in Shengjing Hospital of China Medical University from January 1 to March 31, 2018 were selected. The patients with gallbladder polyps diagnosed by ultrasound were included in the case group, and those without gallbladder polyps were taken as the control group. Age, gender, body mass index (BMI), night shift frequency, education level, Department, meal regularity, drinking history, smoking history, serum triglyceride, serum total cholesterol, hepatitis B surface antigen, serum alanine aminotransferase and serum aspartate aminotransferase levels were compared between the two groups.Results:Univariate analysis showed that age ( P<0.001), gender ( P=0.028), BMI ( P=0.005), night shift frequency ( P=0.021) were the factors with statistically significant difference between the case group and the control group. There were no statistically significant differences between the case group and the control group in terms of education level, department, dining regularity, drinking history, smoking history, hepatitis B surface antigen, serum triacylglycerol, serum total cholesterol, serum alanine aminotransferase, serum aspartate aminotransferase levels ( P>0.05). Logistic regression analysis showed that age, BMI and night shift frequency were the influencing factors in the regression equation ( P<0.05). Conclusion:Age, BMI and night shift frequency may be related risk factors of gallbladder polyps in shift nurses.

Objective To explore the cytotoxicity of the cytotoxic T lymphocyte (CTL) induced by SW480 sonicate sensitized dendritic cells (DC) on the colon cancer cell line SW480. Methods PBMC were separated from the HLA-A*0201 donor and DC were cultured with rhGM-CSF, rhIL-4 and rhTNF-α. The same donor's primary CTL were stimulated by DC loaded with SW480 sonicate. The cytotoxicity of CTL on SW480 (HLA-A*0201 positive) and K562 (HLA-A*0201 negative) was determined by the MTT method. Results The cytotoxicity of the CTL on SW480 was stronger than that on K562 (P ＜0.05). Conclusion The DC vaccine can stimulate specific CTL which can trigger cytotoxic activity on the target cells and this cytotoxicity is related to MHC restriction.

Purpose To investigate the clinical and morphological features as well as immunophenotype of pleomorphic lobular carcino-ma ( PLC) . Methods Seven cases of PLC were retrieved from 34 cases of invasive lobular carcinoma. The clinical data, histologic features, immunohistochemical findings were analyzed. Results The mean age of the patients was 56. 6 years, with a range of 47 to 74 years. PLC might be nodular mass in general macroscopy. Histologically, PLC retained classical or non-classical single cells, but exhibited a greater degree of cellular atypia and pleomorphism and a higher mitotic rate than classic invasive lobular carcinoma ( ILC) . PLC was accompanied by ductal carcinoma in situ ( DCIS) and pleomorphic lobular carcinoma in situ ( PLCIS) . Immunohistochemistry and HER-2 FISH were detected. PLC showed E-cadherin negative (7/7) and p120 cytoplasmic positive (7/7), ER (5/7), PR (5/7), and HER-2 (7/7) mostly negative. 5 cases were characterized by triple negative breast cancer, two of which are basal-like pheno-type. Some cases could be observed nerve invasion (3/7) and axillary lymph node metastasis (4/7). Conclusion PLC is a very rare subtype of invasive lobular carcinoma. In some cases there are nerve invasion and lymph node metastasis. The diagnosis of PLC de-pends on the pathological morphological and immunohistochemical markers.

AIM: To observe the neuroprotective effect of combined treatment with taurine and diazepam against focal cerebral ischemia-reperfusion in rats. METHODS: Sixty male Sprague-Dawley rats were randomly divided into five groups: sham-operation group, vehicle group, taurine group (200 mg/kg, ip), diazepam group (10 mg/kg, ip) and combined treatment group (taurine 100 mg/kg+diazepam 5 mg/kg). Focal cerebral ischemia was induced by the method of middle cerebral artery occlusion (MCAO) in rats, and reperfusion was emerged by removing the thread 2 h later. The drugs were administered respectively at the time of reperfusion, and subsequently repeated once 12 h later. The animals in vehicle group were intraperitoneally injected with isodose normal saline. The neurological deficit score, the brain water content and cerebral infarction were measured 48 h after MCAO. Other 5 group animals of focal cerebral ischemia-reperfusion (n=16 in each group) were set up as mentioned above and accepted treatments 10 h after reperfusion, likewise repeated once 12 h later. Twelve animals in each group were adopted the same management as the previous 5 groups at 48 h after MCAO. The remained 4 animals in each group were sacrificed until two weeks after MCAO to observe the histopathological changes by nissl staining. RESULTS: Compared to vehicle group, the animals in combined treatment group at 2 h or 12 h after MCAO both decreased the neurological deficit score, reduced the brain water content and infarct volume (P<0.01 or P<0.05). The combined treatment significantly alleviated the neurological necrosis as well. The neuroprotective effect of the combined treatment was superior to that of using taurine or diazepam alone. CONCLUSION: These results suggest that combination of taurine and diazepam treatment has a coordinate neuroprotective effect on both the acute and chronic brain damage of focal cerebral ischemia-reperfusion.
