ObjectiveTo compare the clinical efficacy and safety of anesthesia induction between inhalation of sevoflurane and intravenous injection of propofol for laryngeal mask airway (LMA) insertion in elderly patients.Methods40,ASA physical grade Ⅰ ～ Ⅱ patients scheduled to receive elective total knee arthroplasty were allocated to 2 groups at random. Patients in group one( G1 ) received intravenous induction of propofol infusion by a targetcontrolled infusion system which was set at the effect-site concentration of 4.0μg/ml,while patients in group two(G2)received inhalational induction with sevoflurane using vital capacity manoeuver at the target of end-expiratory concentration of 3.0％. We observed the whole procedure of anesthesia induction and LMA insertion, while recording the changes in hemodynamic state and occurrence of adverse events. ResultsMore than 85％ patients achieved LMA insertion at first attempt using either induction manoeuver. Although consciousness loss time in G1 was 39. ls longer than G2, there was no difference in anesthesia induction time for LMA insertion between these two groups. Contrary to a significant decrease in MAP following induction for patients in G1, there appeared hemodynamically stable in patients of G2,while apnea also significantly seldom occurred in G2 as compared to G1 (20％ vs 85％ ,P ＜0. 05).ConclusionAs compared to intrvenous induction with propofol, inhalation induction with sevoflurane provided a valuable alternative for LMA insertion in adults.

Objective To assess the therapeutic effect of music- regulated laser therapy on mild and moderate primary hypertension (PH) so as to provide clinical evidence for the development of an effective non-drug therapy for hypertension. Methods One hundred mild and moderate PH patients were divided into obser-vation ( n = 50 ) and control groups ( n = 50 ) according to their stage of hypertension. There were two phases of treatment with 6 weeks in each phase for a total of 12 weeks. In the first phase, patients in the observation group received music-regulated laser therapy while the control group received drug therapy. In the second phase, the treatments were reversed, with the observation group receiving the drugs. The blood pressure and quality of life (QOL) of all the patients was evaluated after each phase. Results Before therapy there were no significant differences in average blood pressure or QOL between the groups. After the first phase, systolic blood pressure (SBP) and diastolic blood pressure (DBP) had been reduced significantly in both groups, but the decrease was significantly greater in the control group. The score on each item of the QOL evaluation was not significantly different between the two groups. After the second phase, blood pressure had decreased further in the observation group, but no significant change was observed in the control group, and there was no significant difference in blood pressure between two groups. The scores on each item of the QOL evaluation were not significantly different between the two groups, but average somatic symptoms, healthy and pleasant feelings, task perform-ance and life satisfaction were significantly ameliorated in both groups. Conclusions Music-regulated laser therapy can lower the blood pressure of mild and moderate PH patients effectively. Compared with antihyperten-sion drugs, music-regulated laser therapy provides a weaker effect in lowering blood pressure, but plays an e-quivalent role in improving the QOL of patients.

Objective　To investigate the operation treatment of gallbladder carcinoma(GBC). Methods The clinical data of 132 patients with GBC from 1980 to 1999 were analysed. Results　The mean age was 55 years and the occurrence sex ratio in female/male was 1.5∶1. Gallstone was found in 80% of the patients, and 87.1% of the GBC were adenocarcinoma. Before December 1990(forward group), simple cholecystectomy were performed on 11 cases, radical cholecystectomy on 9 cases, extended radical cholecystectomy on 5 cases, palliative extra- or intra- drainge on 15 cases, surgical biopsy on 30% cases. Hospital death occurred in 4 cases, the postoperative complications occurred in 20 cases including biliary fistula in 4 cases, pancreatic fistula in 2 cases. Since January 1991(latter group), radical simple cholecystectomy were performed on 2 cases, radical cholecystectomy on 16 cases, extended radical cholecystectomy on 24 cases; palliative extra- or intra- drainge in 9 cases, surgical biopsy on 8 cases. Hospital death occurred in 1 cases; postoperative complications in 12 cases, including biliary fistula in 1 cases, pancreatic fistula in 1 cases. Radical resection rate was 35.7% in forword group, 72.6% in latter group. Conclusions　Surgical tech-nique progress and application with Peng's Multifunctional Operative Dissector can improve the resection rate of GBC. Extended redical resection is an effective and active method to treat middle or late stage GBC.

Objective To evaluate the expression of STAT3, VEGF and Survivin in human gastric carcinoma and its clinicopathological significance. Methods The expression of STAT3, VEGF, survivin was determined by immunohistochemical staining of specimens from 53 cases undergoing radical gastrectomy and 53 cases of normal gastric mucous membranae. We evaluated the relationship between expression of these proteins and various clinicopothological factors. Results The expression rate of STAT3, VEGF and survivin in 53 gastric carcinoma tissues was 58%, 62% and 74%, respectively, which was significantly higher than those in the normal group(P <0. 01). STAT3 expression correlated with VEGF(r =0. 608 ,P <0. 01) ,survivin(r = 0. 451, P = 0. 001). Positive STAT3, VEGF staining was significantly associated with tumor size, Lauren's classification,lymph node metastasis and clinical staging(P < 0. 05). Survivin staining was significantly associated with Lauren's classification, lymph node metastasis and clinical staging(P <0. 05). Multivariate analysis revealed STAT3 expression and lymph node metastasis were independently prognostic factors of poor survival. Conclusion VEGF, survivin possibly regulated by STAT3 leads to tumor angiogenesis and anti-apoptosis. The expression of STAT3 is an independent prognostic factors in gastric carcinoma.

Applications of network pharmacology are increasingly widespread and methods abound in the field of drug development and pharmacological research. In this study, we choose rosiglitazone compound as the object to predict the targets and to discuss the mechanism based on three kinds of prediction methods of network pharmacology. Comparison of the prediction result has identified that the three kinds of prediction methods had their own characteristics: targets and pathways predicted were not in accordance with each other. However, the calcium signaling pathway could be predicted in the three kinds of methods, which associated with diabetes and cognitive impairment caused by diabetes by bioinformatics analysis. The above conclusion indicates that the calcium signaling pathway is important in signal pathway regulation of rosiglitazone compound, which provides a clue to further explain the mechanism of the compound and also provides a reference for the selection and application of methods of network pharmacology in the actual research.

Inflammation response is the most crucial link in the pathogeneses of spinal cord injury (SCI),and is the basis of secondary damage. NF-κB Signalling pathway is activated excessively after SCI,so that numerous NF-κB possessing biological activities is quickly translocated into the nuclear and regulates the target genes,resulting in heightened inflammation and further tissue damage. Suppressing NF-κB signalling pathway and controlling inflammation response effectively are effective approaches to promoting SCI repair. It is found that curcumin has multiple target molecules to suppress NF-κB signalling pathway,block the excessive activation of NF-κB and reduce the expression of proinflammation cytokines,which plays an important role in SCI repair. This article discusses NF-κB signalling pathway,the contribution of NF-κB signalling pathway to SCI and the role of curcumins inhibition of NF-κB signalling pathway in SCI.

ObjectiveTo investigate the relationship between metastasis-associated gene 1 ( MTA1 )expression and invasive and metastatic ability of cervical cancer cell. MethodsThree kinds of plasmids pcDNA3( control group), pcDNA3-MTA1 ( MTA1 group) and pSilencer3. 1-MTA1-siRNA ( MTA1-siRNAgroup) were transfected into human cervical cancer cell line CaSki cells. Reverse transcription (RT)-PCR and western blot were used to detected MTA1 mRNA and protein expressions. The effects of MTA1 expression on CaSki cell growth and proliferation, cell migration, adhesion and invasion, and cell cycles were tested by methyl thiazolyl tetrazolium (MTT), clone formation experiment, wound-healing assay, transwell assay, adhesion assay and flow cytometry, respectively. In animal experiment, three groups of cells were inoculated to BALB/c nude mouse subcutaneously to observe tumor formation ability. ResultsCompared with control group, MTA1 mRNA and protein were significantly overexpressed in MTA1 group, while MTA1-siRNA group showed lower MTA1 expression. Compared with control group, MTA1 group showed significantly accelerated cell growth; while MTA1-siRNA group showed decreased cell growth since the second day (P＜0. 05). Clone formation number in control, MTA1 and MTA1-siRNA group were 133 ±6, 169 ± 10 and 57 ±5,respectively. MTA1 group showed accelerated cell formation, while MTA1-siRNA group showed the reverse effect compared with that in control group(P ＜ 0. 05 ). At 24, 48 and 72 hours after wounding, the healing ability of MTA1-siRNA group significantly lagged behind that in the control group, while MTA1 group showed accelerated cell healing ability. The adhesion rate of control, MTA1 and MTA1-siRNA group were (69. 3 ± 3. 6) ％, ( 80. 4 ± 5. 6 ) ％ and ( 39. 2 ± 7.4 ) ％ separately at 90 minutes after cell seeding. In contrast with control group, MTA1 group promoted the adhesion of CaSki cell to matrigel matrix, while MTA1-siRNA group inhibited the adhesion process (P ＜0. 05 ). In the migration assay, the number of cells migrated to the bottom side of the membrane in control,MTA1 and MTA1-siRNA group were 153 ± 17,247 ± 38 and 82 ± 10, respectively. The number of cells in the invasion assay were 231 ± 19,354 ± 36 and 76 ± 7, respectively. Compared with the control group, MTA1 group significantly increased the migration and invasion ability, while MTA 1-siRNA group showed lower cell migration and invasion ability (P ＜ 0. 05 ). In cell cycle experiment, no significant differences of cell proportions including G1, S and G2 stage were found among three groups (P ＞ 0.05).In animal experiment, compared with control group,MTA1 group showed accelersted tumor formation and growth,whilethe MTA1-siRNA group showed the reverse effect ( P ＜ 0. 05 ). ConclusionsMTA1 may play its roles to promote cervical cancer cell invasion, migration, adhesion, as well as cell growth and colony formation, while RNA interference against MTA1 may decrease the malignant phenotypes. This study shows that it will be an effective beginning to explore metastasis mechanisms and cancer gene therapy strategy targeting MTA1 in cervical cancer.
