Objective To observe the effect of combination of dexmedetomidine and sufentanil on postoperative analgesia for the highly nicotine dependent patients undergoing esophagectomy. Methods Ninety highly nicotine dependent patients undergoing esophagectomy were randomly allocated into three groups (n = 30 each): low-dose sufentanil group (Group S1), high-dose sufentanil (Group S2), dexmedetomidine and sufentanil group (Group DS). All patients of three groups received postoperative PCIA with following setting: 2 mL/h;bolus: 2 mL; lock time: 5 min; 4 hours limited: 40 mL. The scores of VAS and Ramsay, effective presses/total presses of PCIA, the consumption of sufentanil during 72 h after operation, side effects and the satisfaction degree of patients were recorded. Results Compared with those of group S2, the scores of VAS (both at rest and movement) decreased significantly in group DS from 1 h to 8 h (P<0.05). Compared with those of group S1, the scores of VAS (both at rest and movement) decreased significantly in group S2 and DS from 1 h to 72 h (P<0.05). Compared with that in group S1 and S2, the consumption of sufentanil during 72 h after operation decreased significantly in group DS (P < 0.05). Compared with those in group DS, The numbers of nausea and vomiting were significant decreased in group S1 and S2(P < 0.05). Compared with those in group S1, the remedial cases were significantly decreased in group S2 and group DS (P < 0.05). Conclusion The effect of combination of dexmedetomidine and sufentanil is superior to that of sufentanil in terms of postoperative analgesia in highly nicotine dependent male patients undergoing esophagectomy.

Objective To investigate the correlation of diabetic skeletal muscle disease with macroangiopathy, and to explore the related genes of Shenqi Compound Recipe (SCR) in preventing and treating diabetic skeletal muscle disease by using gene chip technique, thus to reveal the molecular mechanism. Methods KKAy mice were fed with water containing nitri oxide synthase inhibitor of Nω-nitro-L-arginine methyl ester ( L-NAME) and high fat diet to induce the macroangiopathy complicated with type 2 diabetes. The experimental animals were divided into normal c57BL/GJ group, KKAy group, model group, SCR group (in the dosage of 14.4 g·kg-1·d-1) and rosiglitazone group ( in the dosage of 1.33 mg·kg-1·d-1) , 15 in each group. The medication groups were administered the corresponding agents for 8 consecutive weeks just as the modeling began. During the experiment period, blood glucose was monitored. At the end of the experiment, the abdominal aorta and skeletal muscle of mice were taken out for the observation of morphological changes, and differentially expressed genes of skeletal muscle between SCR group and model group, and between model group and KKAy group were detected by gene chip technique. Results SCR had an effect on relieving the atrophy, edema, fracture, and inflammatory changes in the skeletal muscle. There were 198 genes differentially expressed between model group and KKAy group, including 119 up-regulated genes and 79 down-regulated genes. There were 70 genes differentially expressed between SCR group and model group, including 33 up-regulated genes and 37 down-regulated genes. In the two comparison groups, 7 genes ( Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b) showed reversed differential expression. Conclusion Diabetic skeletal muscle disease is associated with macroangiopathy. SCR has preventive effect on diabetic skeletal muscle lesion, and the mechanism may be related to the regulation of Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b gene expression.

Objective: To investigate the effect of ginsenoside Rg3 combined with TRAIL on the apoptosis of lung cancer H358 cells and its possible mechanism. Methods: After the completion of cell culture, H538 cells were treated with TRAIL (0, 50, 100, 200 ng/ ml ) or Rg3 (0, 25, 50, 100 μmol/L) for 48 h, and the cells were grouped according to different treatments, namely control group, 50 μmol/LRg3 group, 100 ng/ml TRAILgroup and 50 μmol/LRg3+100 ng/ml TRAILgroup. The effects of Rg3 and/or TRAILon the proliferation of H358 cells were detected by MTT assay. The effects of Rg3 and/or TRAIL on the morphological changes of H358 cells were observed by DAPI staining. Theapoptosis of H358 cells in each group was detected by flow cytometry. The effects of Rg3 and/or TRAIL on the expressions of death receptor 5 (DR5) and caspase-8 in H358 cells were detected by WB. Results: Compared with the other groups, the proliferation of lung cancer H358 cells was significantly inhibited, while the apoptosis was significantly elevated in the 50 μmol/LRg3+100 ng/ml TRAILgroup (P<0.05).After color developing, cells in 50 μmol/LRg3+100 ng/ml TRAILgroup had nuclear shrinkage, chromatin condensation, increased fluorescence intensity, and late morphological changes such as saturation fragmentation. Compared with the other groups, the expression levels of DR5 and caspase-3 ,8 in the cells of 50 μmol/L Rg3+100 ng/ml TRAIL group were significantly increased (P<0.05). Conclusion: Ginsenoside Rg3 combined with TRAIL can synergistically inhibit the proliferation and induce apoptosis of lung cancer H358 cells. The mechanism may be related to the up-regulation of DR5 and caspase-8 by ginsenoside Rg3.

Objective To study the etiological effect between the spatial variation of lumbar facet orientation and the degenerative lumbar spondylolisthesis(DLS)in axial,sagittal and coronal plane.Methods 85 patients with DLS at L4 and 110 controlsreceived X-ray and CT scanning.The facet angle at L4-L5 was measured in axial,sagittal and coronal plane.Results Compared with the control group, the DLS-angles were lesser and the difference between the left and right was greater in axial,coronal plane(P <0.05).But were greater in sagittal plane(P <0.05).Conclusion The DLS-angles are more sagittal in axial plane,more level in sagittal plane and more erect in coronal plane.The change of spatial orientation in the facet joint is one of etiological factors of degenerative lumbar spondylolisthesis.

Objective To investigate the G protein-coupled receptor kinase 2 (GRK 2) level in peripheral blood lymphocytes with cardiac func-tion in elderly patients with acute myocardial infarction. Methods This study enrolled 40 patients with acute ST-segment elevation myo-cardial infarction (STEMI) and 40 patients with unstable angina. All patients were 65 years or older. Cardiac function was evaluated by echocardiography, and the GRK 2 level in peripheral blood lymphocytes was measured. Patients with STEMI were followed up for 2 years. Results The GRK 2 level in peripheral blood lymphocytes was significantly higher in patients with STEMI than in patients with unstable angina, and was negatively correlated with left ventricular ejection fraction, cardiac output, stroke volume, and left ventricular fractional shortening. The GRK 2 level was significantly elevated in some patients with acute STEMI and poor cardiac function. Conclusions In-creased GRK 2 level in patients with acute STEMI may contribute to poor myocardial systolic function and myocardial remodeling. Meas-urement of the GRK 2 level in peripheral blood lymphocytes may assist in the evaluation of cardiac function and myocardial remodeling in elderly patients with acute STEMI.

Objective To evaluate the effect of rapid-prototyping (RP) fracture model in the teaching of extremity fracture. Methods 60 clinical medical undergraduates of the Fourth Military Medical University, who were receiving “surgery” teaching in 2012, were randomly divided into A and B groups equally by lottery. Undergraduates of Group A were taught by traditional methods while undergraduates of Group B were explained by using RP fracture model about the basic anatomy, fracture mechanism, injury mechanism of important vessels and nerves besides traditional methods. Degree of satisfaction of the undergraduates and examination were applied immediately after class. Original data were imputed into SPSS software (version 17.0) for comparison between the two groups using t-test. Results The difference of the two groups in the degree of satisfaction of the undergradu-ates, the average score of fracture mechanism, injury mechanism, clinical manifestation, key point of diagnosis, treatment principles and the total score all has statistical significance (P=0.000). Conclu-sions Students' self-initiative, learning interest and studying efficiency can be inspired by RP fracture models and their professional examination performance has also improved significantly.

Objective To explore the effect of Shenqi Fufang (参芪复方,SF) on skeletal muscle damage of type 2 diabetes mellitus (T2DM) and its possible mechanism.Methods Eighteen rats with spontaneous type 2 diabetes mellitus (GK) were randomized into the model group,SF group and sitagliptin group with six rats in each group,and six more Wistar rats were selected as the control group.Each group was given high fat diet for 8 weeks to build T2DM model except for the control group.At the same time,the control group and the model group were given normal saline 5 ml/(kg-d) by gastric perfusion,the SF group was given SF extract 1.44g/(kg · d) by gastric perfusion,and sitagliptin group was given sitagliptin phosphate suspension 16ml/(kg · d) by gastric perfusion.Eight weeks later,the levels of serum insulin-like growth factor 1 (IGF-1),tumor necrosis factor-αr (TNF-a) and interleukin-1β (IL-1β)were measured in each group,the gastrocnemius muscle was taken out to get the wet weight and observe the pathological changes,and the expression of p70s6k1 protein was detected.Results Compared with the control group,the wet weight of the gastrocnemius muscle,the serum IGF-1 level and p70s6k1 protein expression in the model group significantly decreased (P ＜ 0.05),while the levels of serum TNF-α and IL-1β significantly increased (P ＜ 0.05).Through pathological observation,there existed gastrocnemius muscle cells atrophy,a larger area of edema and interstitial lymphocyte infiltration.Compared with the model group,the wet weight of the gastrocnemius muscle,IGF-1 content and p70s6k protein expression in the sitagliptin group and the SF group significantly increased,the contents of TNF-α and IL-l β significantly decreased (P ＜0.05),and there were no obvious muscle cell atrophy and edema,and also little inflammatory cell infiltration.There was no significant difference between the sitagliptin group and SF group (P ＞ 0.05).Conclusion SF could reduce the diabetic skeletal muscle injury;the potential mechanism seems to reduce the inflammatory factor content,improve IGF-1 resistance and maintain the skeletal muscle mass.

The academic origin of homogeny of spleen and pancreas is explained from the aspect of Chinese medicine.The authors think spleen faihng to spread essence is the basic pathogenesis to diabetes mellitus.Spleen function of spreading essence is impaired.Thus essence of water and grain could not be spread in the whole body but amass sugar-turbidity,which manifests high blood sugar.Differentiating diabetes mellitus from the viewpoint of spleen,invigorating spleen and benefiting Qi could help spleen to ascend clear.Invigorating spleen-yin and clearing endogenous heat are used.The liver and kidney should be considered.The methods of dissipating phlegm and activating blood circulation could be combined.The treating idea of treating spleen is treating pancreas should be used in preventing and treating diabetes mellitus.
