Objective:To construct eukaryotic expression vectors pEGFP-N2/MafA and pEGFP-C1/MafA,encoding the mouse musculus v-maf musculoaponeurotic fibrosarcoma oncogene family,protein A(MafA)gene,for the further research of its expression in HepG-2 cells.Methods:pRNA of the mouse MafA gene was distilled by RT-PCR from the mouse,and inserted into Hind Ⅲand SalⅠrestriction sites by PCR,then cloned into pEGFP-N2 and pEGFP-C1 vectors to obtain plasmids pEGFP-N2/MafA and pEGFP-C1/MafA.Human liver cancer cells(HepG-2) were transfected with formed plasmids by means of lipidosome.The MafA-EGFP fused protein was viewed directly with fluorensce microscope,and expression of MafA and insulin Ⅱ was detected by RT-PCR.Results:The mouse MafA gene was amplified through RT-PCR and successfully cloned into transfer vectors.The favorite gene sequence could be expressed and was completely consistent with that reported in genebank,but the insulin Ⅱ gene expression was not detected.Conclusion:The recombinant plasmids pEGFP-N2/MafA and pEGFP-C1/MafA were successfully constructed.But the insulin Ⅱgene was not expressed.

Full thickness scalding of 37% TBSA was inflicted io rats. Three days later, the liver of the animals was isolated and the changes of the protein metabolism in the liver and the effects of insulin on the changes were evaluated.It was found that the protein and DMA levels of the liver showed no obvious changes after scalding, but the RNA content increased by 24% and the rate of leucine incorporation by 31%. After the addition of insulin, the leucine content increased by 23.% and 25.8% in the controls and the injured animals respectively. The results indicate that the rate of protein synthesis in the liver of the scalded animals increases, which is likely to be related to the increase of RNA content, and the liver protein synthesis remains to be sensitive to insulin.

This paper is to report the changes of the protein metabolism in the rat soleus muscle in vitro after 37% TBSA full-thickness burns covering one hindlimb and the effects of leucine and insulin on the burned muscle.It was found that there werea significant decreases of the protein content and marked exaggeration of the rates of tyrosine incorporation,tyrosine release and tyrosine net release in the burned muscle.No changes of the above-mentioned parameters could be revealed in the muscle of the unburned limb and the controls.Elevation of leucine concentration in the medium could not improve the protein metabolism of the burned muscle.0.1u/ml of insulin could significantly stimulate the tyrosine incorporation in the muscle of the unburned limb and the controls,but no similar effect was observed on the burned muscle.The results indicate that increased protein degradation of the local burned muscle is responsible for the postburn negative nitrogen balance;administration of leucine alone cannot improve the protein metabolism in the local burned muscle;and the sensivity of the burned muscle to insulin is suppressed.

After first report of local anesthetics on cardiac toxicity was published in 1979, A lot of researches of local anesthetics on the mechanism of cardiac toxicity and its treatments were reported, and some advances were reviewed in this article during recent years.

Objective To compare the medium-term clinical effects of oblique T-shaped volar locking compression plate (LCP) and external fixation (EF) treating type C distal radial fractures.Methods Data of 60 patients with type C distal radial fractures who underwent surgery in our hospital from May 2010 to November 2012 were retrospectively analyzed.36 patients received open reduction with LCP fixation (LCP group),among which there were 21 males and 15 females,and there were 20 left wrists and 16 right wrists with an average age of 45.94±16.29 years old (range,17-80 years old).24 patients received close reduction and external fixation (EF group),among which there were 16 males and 8 females,and there were 15 left wrists and 9 right wrists with an average age of 43.63±14.55 years old (range,16-79 years old).The clinical results of wrist joint were assessed by range of wrist activity,VAS,Gartland-Werley wrist score,postoperative radial tilt angle,radial inclination angle and radial height.Results All the 60 patients were followed up successfully.The LCP group was followed up for 24 to 55 (42.03 ± 8.62) months.The EF group was followed up for 24 to 54 (37.24±9.77) months.In the LCP group,the average VAS score was 1.28±0.78,Gartland-Werley score 2.28±0.78,wrist flexion angle 50.89°±5.53° and wrist dorsiflexion angle 50.69°±5.38°.In the EF group,the average VAS score was 1.38±0.71,Gartland-Werley score 2.92± 1.69,wrist flexion angle 50.96°±5.01° and wrist dorsiflexion angle 51.08°± 5.73°.No statistically differences were found in wrist joint function between two groups.In LCP group,radiological evaluation 2 years after operation showed that the average radial tilt angle was 10.69°±2.29,radial inclination angle 22.53°± 1.95° and radial height 10.63±1.14 mm.In the EF group,radial tilt angle was 6.63°±2.76°,radial inclination angle 16.96°±4.41° and radial height 9.06±0.98 mm.Significant differences were found in radial tilt angle,radial inclination angle and radial height.No statistically differences were found in postoperative complication rates.Conclusion Locking compression plate (LCP) fixation and external fixation (EF) can obtain similar satisfactory medium-term clinical outcome in treating type C distal radial fractures.Comparison with EF,LCP can achieve anatomic reduction under direct vision,and its radiological assessments including radial tilt angle,radial inclination angle and radial height were significantly better than external fixation.

Objective To investigate the effect and function analysis by sulfentanyl in patients with tongue cancer postoperative analgesia.Methods A total of 74 patients with radical resection of tongue cancer in department of anesthesiology with general anesthesia from our hospital were collected, patients or their families signed consent, according to postoperative self-controlled intravenous analgesia drugs divided into experimental group and control group with 37 cases in each group.Patients in control group were treated by fentanyl self-controlled intravenous analgesia;patients in experimental group were treated by sulfentanyl self-controlled intravenous analgesia, determination of the analgesic effect, sedative effect and the changed of vital signs postoperative 2, 4, 8, 12, 24, 48 h,at the same time recorded complications.Results After operation, at different time points analgesic effect and sedative effect were changed in the two groups, the VAS scored of the experimental group was lower than the control group postoperative 2, 4, 8, 12, 24, 48 h time points, the Ramsay Sedation scored of the experimental group was lower than the control group postoperative 2 h, 4 h, 8 h, 12 h time points ( P <0.05 ); the changed of vital signs and adverse reactions between the two groups had no difference within 48 hours ( P >0.05 ) . Conclusion Sulfentanyl in the treatment of patients with radical resection of tongue cancer the analgesic effect and sedative effect are better than fentanyl, has no effect on the vital signs, and the role is security and exact.
