Objective The aim of this study was to investigate the effects of different anesthetic drugs and techniques on serum SIL-2R, IL-6 and TNF-? in cancer patients undergoing elective thoracic surgery, trying to find a reasonable anesthesia for patients with compromised immune function. Methods Eighteen ASA Ⅰ-Ⅱ cancer patients(male 12, female 6) undergoing elective thoracic surgery were studied. The age ranged from 46-47 years. 6 patients suffered from lung cancer and 12 from cancer of esophagus or cardia. The patients received no radio-or chemotherapy before surgery. They were premedicated with intramuscular pethidine 50mg and atropine 0.5mg. Esophogus and cardia cancer patients were randomly divided into two groups: group Ⅱ and Ⅱ . Group Ⅲconsisted of only lung cancer patients. Group I received general anesthesia combined with continuous epidural block and postoperative epidural analgesia. An epidural catheter was inserted at T7-8 or T8.9 before general anesthesia. Anesthesia was induced with 2% thiopental sodium 5mg kg-1 and vecuronimn 0.06-0 .08mg kg-1 and maintained with 1%-2% isoflurane inhalation with epidural 2% lidocaine 6-7m1o h-1 . After operation epidural analgesia was produced with 0.125% bupivacaine 5-6ml h-1 for 72 h. In group Ⅱ the induction of general anesthesia was the same as in group Ⅰ , but anesthesia was maintained with ketamine infusion 1-2mg kg-1h-1 and epidural 2% lidocaine 6-7ml h-1. Postoperative analgesia was produced with epidural 0.1% bupivacaine + 0.0003% fentanyl 5-6m1o h-1 for 72 h. In group Ⅲ the induction and maintenance of anesthesia were the same as in group Ⅱ but postoperative analgesia was produced with epidural 0.1 % ketamine 4-5ml h-1. Blood samples were taken from peripheral vein before anesthesia, before and 2 h after skin incision and on the 1st, 3rd and 5th day after operation for determination of serum SIL-2R, IL-6 and TNF-? by ELISA(Genozyme Co) Results The serum SIL-2R, IL-6 and TNF-? levels were comparable before anesthesia and operation among the three groups. Serum SIL-2R decreased significantly at 2 h after skin incision(P

Objective To analysis clinical effect of Diyu Shengbai tablets combined with granulocyte colony stimulating factor on cancer related fatigue syndrome.Methods II-VI primary cancer 60 patients from January 2011 to December 2013 were admitted to department of internal medicine, Fourth Hospital of Hebei Medical University,and randomly divided into two groups.Control goup(n=30)were treated with granulocyte colony stimulating factor(G-CSF).Experimental group(n=30)were treated with Diyu Shengbai tablets and G-CSF.Results After chemotherapy, ratio of patients in the experimental group appeared fatigue syndrome and changes in leukocyte was significantly lower than that of control group, the difference was statistically significant ( P <0.05 ) . Conclusion Diyu Shengbai tablets combined with G-CSF have better clinical efficacy for leukopenia caused by tumor chemotherapy, the symptom of fatigue also can improve significantly.

AIM: To clone and express the gene of SLC24A6, which provide the basis to illuminate the relationship between the SLC24A6 and insulin release. METHODS: The gene expression of SLC24A6 was analyzed in the insulinoma and normal pancreatic tissues by RT-PCR. The full-length cDNA sequence was subcloned into pET32a vector, and induced expression and purified in ROSSET (DE3) strain. At the same time, the ORF of SLC24A6 was cloned into green fluorescence protein vector pEGFP-C3 to study the location of SLC24A6 in the mouse insulinoma ?-TC3 cells. RESULTS: The mRNA expression of SLC24A6 in the human insulinoma tissue was significantly higher than that in normal pancreatic tissue. The fusion protein of SLC24A6 was a 80 kD protein and was purified successfully by prokaryotic vector in ROSSET strain. The localization of SLC24A6 in the mouse insulinoma ?-TC3 cells was located in the membrane of the cells. CONCLUSION: SLC24A6 might be related with insulin release. The prokaryotic expression of SLC24A6 provides the basis for the study on biological function and protein structure, and the location of SLC24A6 in the insulinoma cell will throw light on the relationship with insulin release.

Objective To explore the feasibility of inhibitor of apoptosis protein 2-mucosa associated lymphoid tissue lymphoma translocation gene 1 (API2-MALT1) fusion gene detection in endoscopic biopsy tissue of primary gastric lymphoma (PGL), and to study the expression of this fusion gene in PGL and its clinical values in diagnosis and treatment of PGL.MethodsA total of 32 suspicious PGL patients underwent endoscopic ultrasonography (EUS) examination and mucosal biopsy.The biopsy specimens were conducted histopathology examination, immunohistochemistry detection and real time RT-PCR for API2-MALT1 fusion gene expression.The expression of API2MALT1 fusion gene in clearly diagnosed PGL and its relation with PGL diagnosis, classification and treatment were analyzed and summarized.ResultsA total of 14 cases of 32 suspicious PGL patients were diagnosed as PGL by histopathology and immunohistochemistry examination, which including 11 cases of gastric mucosa-associated lymphoid tissue (MALT) lymphoma and 3 cases of gastric diffuse large B-cell lymphoma (DLBCL).There were 5 API2-MALT1 fusion gene positive cases, which were all MALT lymphoma, about 5 out of total 11 MALT lymphoma patients.API2-MALT1 fusion gene expression was negative in all 3 gastric DLBCL cases.The depth of lesion invasion and lymph nodes metastasis were more severe in API2-MALT1 fusion gene negative group than those of positive group.There were 2 of 5 API2-MALT1 fusion gene positive cases were Hp positive, and 5 of 9 negative cases were Hp positive.The anti-Hp therapy in 5 API2-MALT1 fusion gene positive cases was ineffective,however, chemotherapy was effective.In negative group, 2 of 5 Hp positive cases was complete remission and 4 Hp negative cases were ineffective with anti-Hp therapy.ConcltsionsAPI2-MALT1 fusion gene is common genetic abnormality in gastric MALT lymphoma.The detection of this fusion gene expression in endoscopic biopsy specimen by real time RT-PCR is clinically practical, and the detection of this fusion gene is valuable in the assessment of PGL diagnosis, treatment and prognosis.

Mimecan belongs to a family of leucine-rich proteoglycans that are secreted into the extracellular matrix. In order to investigate the function of mimecan, the coding region of mimecan was amplifed from a human pituitary cDNA by PCR and the recombinant prokaryotic expression vector pGEX-M was constructed. The vactor was transformed into E.coli BL21(DE3)and the GST-M fusion protein of 38 Kd was ecpressed in the bacteria under induction of IPTG. After purification, the fusion protein was infucted into New Zealand rabbits to prepare polyclonal antibody. The antibody was tested by Western blotting for their specificity and sensitivity. Using the antibody it was found the mimecan was expressed highly in certain types of human pituitary tumor tissues. These results make it possible for studying the biological function of mimecan.
