Objective To investigate the role played by fibroblast growth factor-21 (FGF-21) in glucoselipid metabolism in mice adipocyte and hepatocyte. Methods FGF-21 over-expressive vector and FGF-21-shRNA vector were transfected to Hepa1-6 hepatocyte and 3T3-L1 adipocyte, respectively. FGF-21 protein levels were evaluated by Western blotting, glucose uptake rate (GUR) was evaluated by radioimmunoassay. The mRNA expression of transcription factors was detected by real-time quantitative PCR. Results Transfection of pcDNAFGF21 significantly increased FGF-21 expression in both liver and fat cells (4.8 fold and 4.2 fold, both P<0.05). Moreover, FGF-21 expressions were down-regulated by 86. 3% and 77. 8% with pGenesil-FGF21,respectively (both P<0.05 ). The FGF-21 up-regulation markedly increased GUR and decreased intracellular triglycerides content in the 3T3-L1 adipocyte. Meanwhile, the up-regulation of glucose transporter-1, insulin receptor substrate-1 (IRS-1), PPARγ, adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL),and adipocyte fatty acid binding protein 2 ( ap2 ) mRNA expressions were also observed ( all P<0. 05 ). The reverse changes happened in FGF-21 deficient adipocyte except IRS-1. In hepatocyte, FGF-21 has no effect on GUR.FGF-21 over-expression reduced PPARγ, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), and phosphoenolpyruvate carboxykinase (PEPCK) mRNA expressions, and increased low-density lipoprotein receptor expression (P<0.05). Conclusions FGF-21 regulates glucose homeostasis and accommodates intracellular fat content in adipocyte. In hepatocyte, FGF-21 plays an important role in gluconeogenesis and cholesterol metabolism.

Objective To study the feasibility of transumbilical single-incision laparoscopic surgery ( SILS) in the treatment of tubal pregnancy, as compared with conventional multi-port laparoscopic surgery. Methods Sixty-two patients diagnosed as tubal pregnancy undergoing laparoscopic surgery at this hospital between September 2013 and June 2014 were selected for investigation. There were 29 cases of transumbilical SILS ( SILS group) and 33 cases of conventional multi-port laparoscopic surgery ( MPLS group) . We retrospectively reviewed the medical records of all patients and analyzed the surgical outcomes, including operative time, blood loss, surgical complications and hospital stay. Results In both groups, all procedures were performed without failure.No conversion to open surgery or additional skin incision was needed.There were no differences between the SILS and MPLS groups in the operation time [(51.5 ±10.8) min vs.(47.3 ±9.4) min, t=1.637, P=0.107], the mean estimated blood loss [(15.5 ±10.5) ml vs.(18.4 ±12.2) ml, t=-0.996, P=0.323], the absolute decrease of hemoglobin from preoperative to postoperative [(14 ± 5) g/L vs.(13 ±4) g/L, t=0.874, P=0.386], the postoperative hospital stay [(3.5 ±0.9) d vs.(3.8 ±0.8) d, t=-1.390, P=0.170], and the incidence of postoperative fever (2 cases vs.3 cases, χ2 =0.000, P=1.000).Follow-up for 1-3 months ( mean, 1.8 months) in all the cases showed smooth recovery and no postoperative complications. Conclusion SILS is a feasible and safe approach in the treatment of tubal pregnancy.

MicroRNA (miRNA) negatively regulates gene expression at the post-transcriptional level.Studies find that the abnormal expression of miR-151-5p in various human tumors may play an important role in the development of human tumors,especially in the invasion and metastasis.Further studies of miR-151-5p contribute to a more in-depth understanding of tumor invasion and metastasis,which have potential value in tumor diagnosis,treatment and prognosis.

Objective To investigate the possibility of human gastric carcinoma cells apoptosis induced by arsenic trioxide and its mechanism.Methods After treatment with arsenic trioxide, the cytotoxicity to human gastric carcinoma cells MKN45 was quantified using trypan blue exclusion, and IC 50 was determined. Apoptotic cells were detected with flow cytometry, DNA cytofluorometry, DNA electrophoresis. Results Arsenic trioxide inhibited the growth of human gastric carcinoma cells MKN45 in a dose-dependent manner in a certain range of dose with a IC 50 of (11.05?0.25)?mol/L; Apoptotic peak, characteristic morphologic features of apoptosis and DNA ladder were observed in human gastric carcinoma cells MKN45 treated with 1~10 ?mol/L arsenic trioxide. Conclusions Arsenic trioxide can induce apoptosis of human gastric carcinoma cells MKN45, suggesting a great potential in the treatment of gastric carcinoma.

Objective:To explore the therapeutic potential of preemptive targeting of the epitope spreading cascade by adoptive transfer after EAE onset of immunoregulatory T cells specific for the MBP87-99 spreading determinant.Methods:EAE was induced by PLP139-151 in SWXJ mice, all mice were weighed and examined daily for neurologic signs. On days 6 after EAE onset, mice were injected with IL-2prom→IL-10cDNA-transfected Th2/Tr1-like T cells specific for MBP87-99,PLP104-117,or BSA. Finally demyelination was quantified by analysis of digitized images of PLP immunostained spinal cord sections.Results:Mice received Th2/Tr1-like T cells specific for MBP87-99 had a significantly improved clinical outcome(P=0.02) compared with control mice, reduction in the relapse rate and delay in mean time to onset of first relapse were also observed(P

Objective To evaluate superselective external carotid artery embolization before transnasal endoscopic resection in treating nasopharyngeal angiofibroma.Methods Superselective external carotid artery embolization was performed in 20 patients with nasopharyngeal angiofibroma one to three days before transnasal endoscopic resection was carried out.The clinical data,including the volume of blood loss during the surgery,the operative time and the complications,were retrospectively analyzed.Results Superselective external carotid artery embolization was successfully preformed in all 20 patients,which was followed by the transnasal endoscopic resection within 3 days.The average volume of blood loss during the surgery was 155 ml and the total time of operation was 75 minutes.Mild complications occurred in 6 patients after embolization,which were subsided after symptomatic management.No serious complications occurred after surgical resection.The mean hospitalization days of the patients were 3.5 days.Conclusion Preoperative superselective external carotid artery embolization of nasopharyngeal angiofibroma can markedly reduce the blood loss during surgical resection,apparently shorten the operative time and effectively lower the occurrence of complication after the operation.Superselective external carotid artery embolization combined with transnasal endoscopic resection should be regarded as an ideal therapy for nasopharyngeal angiofibroma.
