Objective To explore the effect of preoperative local blocking with compound lidocaine hydrochloride (CLH) on postoperative pain of patients undergoing craniotomy.Methods40 patients suffered from superatentorial occupying lesion and scheduled for craniotomy were randomly divided into the CLH group and control group with 20 cases in each group. In the CLH group, local blocking with CLH was performed just before craniotomy, while in control group local blocking with 0.5% procaine was performed preoperatively and all patients of two groups used patient-controlled intravenous analgesia (PCIA) with fentanyl postoperatively. Postoperative pain was assessed for 48 hours according to visual analogue scale (VAS), and the comparison of analgesia-related postoperative complications of the two groups was demonstrated.ResultsThere was no significant difference in VAS postoperatively and incidence rate of complications between two groups ( P>0.05).ConclusionCompound lidocaine hydrochloride local infiltration may provide a safe and effective analgesia for postoperative pain in patients after craniotomy.

OBJECTIVE: To observe the effect of ginseng fruit saponins (GFS) on insulin sensitivity index in high fat-fed rats. METHODS: An animal model of insulin resistance was established by injecting low dose of streptozotocin (STZ) in high fat-fed rats. Effect of GFS on insulin sensitivity was detected with glucose infusion rate (GIR) by euglycemic hyperinsulinemic clamp technique. RESULTS: The level of fasting blood glucose and insulin in untreated group increased more significantly than that in normal control group (P<0.05, P<0.01), while the index of GIR decreased significantly (P<0.01). As compared with the untreated groupìthe parameters of GFS-treated groups were improved significantly in a dosage-dependent manner (P<0.05, P<0.01). CONCLUSION: GFS can improve experimental insulin resistance in rats.

OBJECTIVE:To systematically review the efficacy and safety of Xiaoke pill versus glibenclamide in the treatment of type 2 diabetes mellitus,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Medline, PubMed,EMBase,Cochrane Library,CBM,CJFD,Wanfang Database and VIP Database,randomized controlled trials (RCT) about the Xiaoke pill(test group)versus glibenclamide(control group)in the treatment of type 2 diabetes mellitus were enrolled. Meta-analysis was performed by using Rev Man 5.2 software after document selection,data extract and quality assessment by Co-chrane systematical evaluation. RESULTS:A total of 15 RCT were included,involving 3 319 patients. Results of Meta-analysis showed the hemoglobin A1c (HbA1c) level [MD=-0.39,95%CI(-0.75,-0.02),P=0.04],fasting plasma glucose (FPG) level [MD=-0.70,95%CI(-1.27,-0.12),P=0.02],2 h PG[MD=-0.87,95%CI(-1.55,-0.20),P=0.01],incidence of thirst with desire for drinks [RR=3.35,95%CI(1.92,5.85),P<0.001],incidence of tiredness and debilitation[RR=5.74,95%CI(3.52, 9.36),P<0.001] and incidence of hypoglycemia [RR=0.67,95%CI(0.49,0.91),P=0.01] in test group were significantly lower than control group,the differences were statistically significant.

Objective To investigate the role of outer membrane protein in clinical isolated car-bapenem resistance Acinetobacter baumannii. Methods Carbapenem resistance and sensitive strains were collected from the same patient. After MIST and REP-PCR analysis, carbapenemases were detected by isoe-lectric focusing. Different expressed membrane proteins were identified by two-dimension electrophoresis and mass spectrometry analysis. We also used efflux pump inhibitor PAβN(Phe-Arg-β-naphthylamide) to con-firm the phenotype. Results Carbapenem resistance and sensitive strains were attributed to the same pat-tern. At positions of P17.6 and P19.0, two β-lactamases were expressed in two investigated strains, no cabapenemases were detected. Six differential expressed membrane proteins were identified, a 34 × 10~3 membrane protein that was confirmed by efflux pump inhibitor PAβN experiment (imiponem MIC decreased from far above 32 μg/ml to 8μ/ml) and OprD and CarO. Conclusion Up-regulation of exported protein accompanied with down-regulation of OprD and CarO other than carbaponemases are responsible for carbap-enem resistance in A. baumannii.

Objective The rapid multiplex PCR (MPCR) system for detection of genes encoding aminoglycoside resistance in Staphylococcus aureus was developed. The distribution of antibiotic resistant genes acc(6')-Ie+aph(2″), aph(3')-Ⅲa and ant(4')-Ia in Guangzhou was analyzed using the established system.Methods S. aureus strains were identified and susceptibility tests were performed using VITEK-60 or PHOENIX-100 system as recommended by the manufacturer. Aminoglycoside resistance was determined by disk diffusion method. MPCR system for detection of antibiotic resistance genes was optimized.Results The MPCR assay was established successfully. The prevalence of acc(6')-Ie+aph(2″), aph(3')-Ⅲa and ant(4')-Ia in the 124 clinical S. aureus isolates was 62.1%, 32.3% and 1.6%, respectively as analyzed by MPCR. Good correlation between antibiotic resistance phenotypes and genotypes was observed. One or more of the genes encoding aminoglycoside modifying enzymes could be detected in all gentamicin- or netilmicin- or amikacin-resistant isolates. The acc(6')-Ie+aph(2″) gene was identified in 72 of 74 mecA-positive isolates.Conclusions This MPCR system could be used for rapid and reliable analysis of the antibiotic-resistant genotypes of clinical S. aureus isolates. The gene acc(6')-Ie+aph(2″) may be the predominant determinant of aminoglycoside resistance, followed by gene aph(3')-Ⅲa. The prevalence of ant(4')-Ia gene is relatively low.

Objective To observe the regulation of Toll-like receptor 4 (TLR4) signal and the release of inflammation factors after angiotensin Ⅱ (Ang Ⅱ) stimulation in rat mesangial cells under high glucose condition,revealing the innate immune-related mechanism of injury by Ang Ⅱ on mesangial cells under high glucose.Methods After synchronization,cells incubated with Ang Ⅱ (10-7 mmo/L) and/or high glucose (25 mmol/L) were used as the stimulation group,cells without stimulation were as normal control (5.6 mmol/L glucose).To determine the role of TLR4 and the adaptor myeloid differentiation factor 88 (MyD88),equal number of HBZY-1 cells were added with 10-5 mmol/L irbesartan and/or TLR4 blocker (10 mg/L) for 1 h and then incubated with Ang Ⅱ (10-7 mmo/L) and/or high glucose (25 mmol/L) for 12 h or 24 h respectively.Real-time PCR was used to analyze TLR4 mRNA and MyD88 mRNA expression after 12 h.Immunofluorescence was used to observe TLR4 protein expression after 24 h; Western blotting was used to observe TLR4,MyD88 and nuclear factor κB (NF-κB) protein; ELISA was used to detect the concentration of MCP-1,IL-6 in cell supernatant respectively.Results Compared with normal control group,TLR4 mRNA and MyD88 mRNA were highly expressed in high glucose or Ang Ⅱ-induced HBZY-1 cells (P ＜ 0.01),TLR4,MyD88 and NF-κB protein as well as MCP-1,IL-6 were also up-regulated significantly (P ＜ 0.01).Compared with high glucose or Ang Ⅱ group,MyD88 and NF-κB protein as well as MCP-1,IL-6 were further up-regulated markedly in Ang Ⅱ and high glucose costimulated group (P ＜ 0.01).In HBZY-1 cells that were preincubated with irbesartan and/or TLR4 blocker,TLR4 and MyD88 protein expression were obviously inhibited,IL-6 and MCP-1 production were also decreased remarkably compared with high glucose and/or Ang Ⅱ group (P ＜ 0.01).Conclusions High glucose and Ang Ⅱ stimulate the release of proinflammatory factors in rat glomerular mesangial cells via TLR4-MyD88 pathway.This process is inhibited by irbesartan or TLR4 blocker via modulation of the signal.Ang Ⅱ has the positive-regulation potential on the release of inflammation factors via TLR4 signal in rat mesangial cells under high glucose condition.

Objective To study the efficacy and toxicity of gensenoside-Rg3 (Rg3) combined with radiotherapy on non-small cell lung cancer ( NSCLC ) at advanced stages (Ⅲ and Ⅴ ).Methods Sixty-three patients with stage Ⅲ or Ⅳ NSCLC were divided randomly into two groups:treatment group ( n =35 ) treated with Rg3 combined with radiotherapy and control group ( n =28 ) treated with radiotherapy alone.The efficacy and side effects were compared after the treatment.Results The response rate ( CR + PR) of the treatment group was 57.14％,significantly higher than that of the control group (32.14％,x2 =3.91,P ＜ 0.05).The median survival time of the treatment group was 14.2 months,significantly longer than that of the control group ( 11.2 months,x2 =2.07,P ＜ 0.05 ).The one-year survival rate of the treatment group was 62.86％,significantly higher than that of the control group (39.29％,x2 =4.40,P ＜0.05).The incidence rates of side effects of the treatment group were all lower than those of the control group,but there were not significant difference. Conclusions Gensenoside-Rg3 combined with radiotherapy is effective for advanced stage NSCLC,with attenuation and synergistic effects.
