Objective To evaluate the efficacy of intraperitoneal hyperthcrmic chemoperfusion in combination with interleukin 2 in the treatment of malignant ascites.Methods A total of 47 patients aged 47-75 years with malignant ascites were randomly divided into two groups:the experimental group and the control group.All patients received a closed drainage and were treated with paclitaxel liposome,cisplatin (DDP),interleukin-2 and dexamethasone by intraperitonealinfusion.Patients were asked to change the body position.In addition,the patients in experimental group were received the high frequency hyperthermia immediately at a temperature of 42℃ to 43℃ for 90 minutes.Results The remission rate (RR) was higher in the experimental group than in the control group (75.0 ％ vs.43.5％,x2 =4.85,P＜0.05).The median survival time (MST) was longer in the experimental group than in the control group (34 weeks vs.21 weeks,P＜0.05).There were no significant differences in adverse reaction incidences between groups (P ＞ 0.05).Conclusions Compared with intraperitoneal chemoperfusion alone,the intraperitoneal hyperthermic chemoperfusion has a higher RR and longer MST with no increased adverse reaction incidence,which can be in the clinical application.

Objective The aim of this study was to explore the association of tumor necrosis factor-α (TNF-α)promoter-308A/G polymorphism with rheumatoid arthritis(RA)susceptibility in East Asian population based on the meta-analysis. Methods We searched all the publications about the association between TNF-α promoter -308A/G polymorphism and RA in East Asian population from PubMed, Ebsco, Chinese Biomedical Literature Database(CBM), Chinese National Knowledge Infrastructure(CNKI), and Wanfang (Chinese). Meta-analysis was performed for genotypes AA versus GG, GA versus GG, AA versus GG+GA,GA+AA versus GG, and A allele versus G allele in a fixed/random effect model. Results A total of 4 studies (957 cases and 1196 controls)were included in the current meta-analysis(three Chinese and one Japanese studies). When all groups were pooled, significant association of A allele and decreased RA risk was found (OR=0.36, 95%CI=0.16～0.80, P=0.01). When analyses were limited to race homogeneous population,significant association of A allele and decreased RA risk was found in Chinese population(OR=0.40, 95%CI=0.16～1.01, P=0.05). Conclusion This meta-analysis demonstrates significant negative association between TNF-α promoter-308A/G polymorphism and RA in East Asian and Chinese population.

Objective To discuss the significance ofbispectral index (BIS) monitoring during the patients after general anesthesia while leaving the post-anesthetic intensive care unit (PAICU). Methods Seventy-five cases after general anesthesia were selected. When they were sent out of the PAICU, recorded their BIS. Results Twenty-one cases with BIS 90 - 100,48 cases with BIS 80 - 89 in slight calm and hypnosis,5 cases with BIS 70 - 79, and 1 case with BIS 50 - 60. Conclusions Without BIS monitoring,when sent out of the PAICU,most patients after general anesthesia are gently sedated and without too much risk. But still some patients are deeply sedated. BIS monitoring provides a nice reference for the patients while leaving the PAICU.

With the development of organ transplantation for nearly half a century, currently the hot issues in clinical renal transplantation have already shifted to the application of low toxicity immunosuppressive drugs and their projects, as well as the research of technique which induces low or no immunity response to the specific donor. At present the main effective strategies of inducing immune tolerance are donor specific blood transfusion and donor specific bone marrow transplantation. This article summarizes the background, mechanism and clinical application of these two strategies.

microRNAs (miRNAs) are short non-protein-coding RNAs,which play important roles in the cell proliferation,differentiation,apoptosis,as well as activation of oncogenic and antioncogenic signals.Researches show that the abnormal expressions of miRNAs are closely related to the tumorigenesis,histological type,diagnosis,treatment and prognosis of lung cancer.So miRNAs may be the most potential and promising therapeutic targets for lung cancer.

Muscle recently has been identified as a good source of adult stem cells that can differentiate into cells of different lineages.Researchers have identified two types of stem cells in skeletal muscle.Further research is necessary to delineate the relationship between different populations of musclederived stem cells(MDSCs)and between MDSCs and other adult stem cells.The methods used to isolate these cells appear to influence the stem cell characteristics.As these efforts continue,the potential for MDSCsbased therapy for other musculoskeletal injuries,as well as for cardiac and smooth muscle injuries,is currently being explored.The behavior,biocharacteristic,isolation,differentiation and the probability of application to regenerate lost or diseased tissue of MDSCs were summarized.

Objective To investigate the correlation between the formation of pigmented biliary calculus and biliary H.pylori infection.Methods Bile from 35 patients with pigmented biliary calculus and 10 healthy controls was cultured for aerobic,anaerobic and H.pylori.The expression of H.pylori- DNA in bile,bile duct mucosa and pigmented calculus were determined by PCR.The expression of H. pylori associated protein in bile duct mucosa was determined by Western-blot and Warthin-Starry staining.Results H.pylori culture was negative in all bile samples.In 35 patients with biliary pigmen- ted calculus,H.pylori was detected by PCR in the center of calculus,bile and bile duct mucosa of 14.29%,31.43% and 56.67% patients,respectively.Among H.pylori-DNA positive bile samples,7 contained anti-CagA antibodies,and 6 contained Vac A.in addition to Vacuolating cytotoxin(35000), glycoprotein(30000),Urase Band Urase A.Bacteria resembling H.pylori by Warthin-Starry stainning were found in 7 of 30(23.33%)bile duct mueosal samples from patients with biliary pigmented calculus. H.pylori-DNA and its associated protein were not detected in all bile and bile duct mucosae samples from the healthy controls.Conclusions The evidence of H.pylori-DNA and its associated protein in biliary system might indicate the role of H.pylori in the formation of biliary pigmented calculus.

BACKGROUND:Activating transcription factor 4 is found as an activating factor that can regulate osteogenic differentiation and function, and plays a critical role in the osteogenic differentiation.
OBJECTIVE:To investigate the expression and significance of activating transcription factor 4 in the osteogenic differentiation of bone marrow mesenchymal stem cells from Sprague-Dawley rats.
METHODS:Bone marrow mesenchymal stem cells from Sprague-Dawley rats were cultured using the whole bone marrow adherence method, and ossification revulsant was added to induce passage 3 cells. cells with no osteogenic induction served as controls. RT-PCR and western blot assay were employed to dynamical y monitor expression of activating transcription factor 4.
RESULTS AND CONCLUSION:RT-PCR results showed that activating transcription factor 4 mRNA expression increased with the increasing osteogenic differentiation, and peaked at day 16. Western blot analysis showed that the protein expression of activating transcription factor 4 tended to increase with the increasing osteogenic differentiation, peaked at day 16 and stil maintained at a higher level at day 19. Compared with the uninduced cells, activating transcription factor 4 in the induced cells exhibited a higher expression at mRNA and protein levels (P<0.05). These findings indicate that activating transcription factor 4 expression is elevated during osteogenic differentiation, showing a positive correlation with osteogenic ability of bone marrow mesenchymal stem cells.
