Objective Antiphospholipid antibody and factor Ⅻ deficiency are among the coagulation disorders that have been implicated in many thrombembolic events. The aim of this study was to investigate the prevalence of antiphospholipid antibodies and factor Ⅻ deficiency in patients with retinal vein occlusion (RVO). Methods The investigation was a case control study. The periphery blood was collected from a cohort of 33 consecutive patients with RVO and 30 age- and gender-matched normal subjects. Anticardiolipin antibody (ACA) was detected by ELISA as binding index (BI) =A value/standard A value. The lupus anticoagulant antibody was examined by APTT test and the activity of factor Ⅻ was detected. This study was approved by The Human Research Ethics Committee of this hospital, and written informed consent was obtained from all the subjects before initiation of any study protocol. Results The total positive rate of APA in RVO group was 24. 24% (8/33), showing a insignificant difference in comparison with control group (6. 67%, 2/30) (P = 0. 085). The positive rate of anticardiolipin antibody in RVO group was 18.18% (6/33), presenting an obvious enhance in control group (P = 0. 025) . Three patients in RVO group disclosed positive response for IgG-anticardiolipin antibody, one patient for IgM-anticardiolipin antibody, two patients for both isotypes IgG and IgM anticardiolipin antibodies, and two patients revealed positive reaction for lupus anticoagulant antibody. The presence of lupus anticoagulant antibody among the patients with ≤ 50 years and ＞ 50 years was similar to that in age-matched controls (P =0. 160, P =0. 206). Factor Ⅻ deficiency was found in 14 of 33 patients(42. 42%) and in 4 of 30 controls(13. 33%) (P = 0. 013). The prevalence of factor Ⅻ deficiency among the patients with ≤50 years and ＞ 50 years was similar to that in age-matched controls (P = 0. 206, P = 0. 052) . Conclusion Our results indicate that the prevalence of ACA and factor Ⅻ deficiency in RVO patients appears to be correlated.

Objective To investigate the pathogenesis of hepatorenal syndrome(HRS),especially the role of the vasoconstrictor that and vasodilator that played in the process.Methods The patients were divided into two groups for observation:The patients of chronic hepatitis with HRS were observational group,the patients of chronic hepatitis without hepatorenal syndrome were control group.Immunoenzyme technique was used for detecting the quantity of renin、atrial natruretic polypeptide、nitric oxide and endothelin in blood and ascites of all patients in two groups respectively.Then we compared the data of the two groups.Results Compared with those of the control group,rennin and endothelin in blood and ascites of the observational group increased significantly(P

Objective To study clinical and histopathological features of high-risk small renal carcinoma and provide theoretical basis for the individualized treatment.Methods This retrospective study analyzed the clinical and histological data of 21 patients of high-risk small renal cell carcinomas which were highly aggressive or advanced stage, admitted from Jan 2000 to July 2015.There were 15 males and 6 females,and the average age was (61.5 ±7.1) years (ranged 27 to 75 years).The mean diameter of tumors was 3.3cm (ranged 2.0 to 4cm).The study mainly focused on pathological character and stage, Fuhrman grading, existence of perirenal tissue or vascular invasion, venous embolus and distant metastasis.Results Of all these 21 cases, 17 cases were clear cell carcinomas, 1 was papillary carcinoma, 2 were hybrid cellular tumor ( malignant rhabdoid tumor and sarcomatoid carcinoma) and 1 was sarcomatoid carcinoma. Among the 17 clear cell carcinoma cases, 12 were Fuhrman grade Ⅱ, 5 were grade Ⅲ and one was gradeⅣ.Tumor infiltrated renal vein or its branches and renal vein embolus were found in 7 cases.The tumor infiltrated perirenal or renal sinus fat were found in 11 cases.Synchronous lung and local lymph nodes metastasis were found in 3 patients respectively.Moreover, there was 1 case with metastasis to the brain (FuhrmanⅣ).The final clinical stage were T3a N0M0 in 14,T1a N1M0 in 3 and T1a N0M1 in 4 cases. Conclusions Small renal tumors are heterogeneous in its biological behavior and the minorities are aggressive with infringement of perirenal fat or simultaneous local lymph node or distant metastasis.When the tumor is greater than 3.0 cm in diameter and with high grade in Fuhrman classification, sarcomatoid carcinoma are more likely to be highly aggressive and advanced stage.

Objective To establish a platinum resistance nude mice model of epithelial ovarian cancer (EOC) and investigate its resistance to cisplatin (DDP) biological characteristics, so as to provide evidences for exploring chemoresistence mechanisms and screening for reversal targets in vivo micro-environment. Methods The resistance model was produced by repeating a crossover subcutaneous injection of human ovarian cancer SKOV3 cells labelled green fluorescent protein(GFP) and transplatation of tumor fragment into nude mice. Two kinds of cancer cell lines of SKOV3/DDPⅠand SKOV3/DDPⅡwere induced with acquired resistence to DDP. The chemosensitivities of EOC cells to DDP were tested and half maximal inhibitory concentration(IC50) was measured by methyl thiazolyl tetrazolium (MTT) and flow cytometry (FCS). Dynamic analysis among the concentration of DDP treatment and cell apoptosis, cell cycle phase distribution and intracellular DDP concentration. The expression of PTEN, STAT5, XIAP, BRCA1 and MDR1 were examined by real time quantitative reverser transcription PCR (qRT-PCR) in vivo. Results IC50 value of cisplatin for SKOV3/DDPⅡ were 2.83 ± 0.12 and 3.82 ± 0.19 folds than those for SKOV3/GFP by MTT and flow cytometry, separately. SKOV3/DDPⅠwere 2.20±0.16 and 3.40±0.20 folds. The apoptosis rate of SKOV3/DDPⅡ and SKOV3/DDPⅠ were decreased significantly at 29.7 and 39.6μmol/L DDP when treatment for 36 hours,which were lower than that of SKOV3/GFP cells [(57.0±1.4)%vs (37.6 ± 4.36)%vs (83.1 ± 2.71)%,P=0.024;(74.4 ± 2.3)%vs (50.5 ± 3.4)%vs (87.4 ± 4.0)%,P=0.001]. SKOV3/DDPⅠ and SKOV3/DDPⅡ was positively related with cisplatin processing time. Intracellular DDP accumulation of SKOV3/DDPⅡand SKOV3/DDPⅠwere lower than SKOV3-GFP in dynamic processes(P<0.05). Besides intracellular DDP accumulation of SKOV3/DDPⅡ also lower than SKOV3/DDPⅠin dynamic processes (P<0.05). Transplanted tumor of SKOV3/GFP appeared organelle degradation and nuclear membrane imcompleted after five times DDP injection with concentration of 4 mg/kg. SKOV3/DDPⅡand SKOV3/DDPⅠdid not generate these phenomenon untill eighth DDP injections with concentration of 4 mg/kg. STAT5 and BRCA1 of SKOV3/DDPⅡwere increased with DDP treatment at concentration of 4 mg/kg. Expression of XIAP from SKOV3/DDPⅡwas positive correlated with injection times. STAT5,XIAP and BRCA1 of SKOV3/DDPⅡwere up-regulated 3.86,28.1 and 14.6 folds than those in SKOV3/GFP cells after eighth DDP treatment, separately. While PTEN of SKOV3/DDP Ⅱ was decreased 3.77 folds. Conclusions We have successfully established platinum-resistent EOC mice model,which provides a new platform for further study on chemoresistant reversal and individualized clinical treatment. The results shown that potential mechanisms of SKOV3/DDPⅡDDP-resistance included over-expressed BRCA1 gene may be promote DNA damage repair, elevate XIAP gene to decrease cell apoptosis,up-regulated STAT5 gene and decrease PTEN gene to stimulate proliferation.

Objective To investigate whether the defective interfering(DI) particles of Paramyxovirus, Tianjin strain could be used as a candidate adjuvant. Methods DI particles were separated and purified. After being identified, it was equally mixed with the inactivated poliovirus (PV) vaccine. Kunming mice were administered subcutaneously with the mixture, besides we set groups of inactivated PV vaccine containing Al(OH) 3 as an adjuvant, inactivated PV vaccine of which the dose was doubled without any adjuvant, and negative control. Sera were collected in the 14th day after immunization, and the specific antibodies of PV were detected. T/B lymphocyte stimulation indexes(SI) were counted through the lymphocyte proliferation tests. The quantities of IFN-γ/IL-4 produced by the splenocytes which were stimulated again by PV antigen were detected. Results The SI and the quantity of IFN-γof the mice in the group of inactivated PV vaccine combining with DI particles of Paramyxovirus, Tianjin strain were more than other groups. Conclusion DI particles of Paramyxovirus, Tianjin strain could enhance the immune response of inactivated poliovirus, especially the cellullar immunologic response of Th1 type.
