Object To establish a calli culture system for the rapid propagation of Speiraea japonica L. f.. Methods Callus and shoot induction were carried out on MS, 6, 7 V or B 5 media with different parts of the plant such as stem tip, tender leaves and petiole as explants. Results A calli culture system was established for the rapid propagation of S. japonica. Conclusion MS cultural medium was found to be most suitable for calli induction. MS with 2.0 mg/L 2,4 D+0.3 mg/L KT can induce calli when the explants were used for the induction, with stem tips being the most satisfactory explant. Clusters of seedlings can be induced on MS+2 mg/L BA+0.1 mg/L NAA and when these seedlings were transferred to 1/2 MS +0.25 mg/L BA+0.5 mg/L NAA medium, root were developed to give young seedlings.

This study was aimed to screen antibacterial agents against 9 pathogenic bacteria from 240 extracts of 60 traditional Chinese medicinals ( TCM ) . And the minimum inhibitory concentration ( MIC ) test was applied on extracts with positive results. The disk diffusion was employed to screen the antibacterial activity preliminar-ily among 240 extracts. The MICs of active extracts were tested by liquid culture method (double dilution method). The results revealed that 104 extracts show antibacterial activity on one or more strains, 20 of them show strong inhibition on three commonly seen bacteria ( MIC < 0 . 2 mg/mL ) . It was concluded that ethanol , acetone and hexane extracts of 11 TCMs including Salvia miltiorrhiza, Cnidium monnieri, Polygonum tinctorium, Taraxacum mongolicum, Morus alba, Glycyrrhiza uralensis, Curcuma longa, Arnebia euchroma, Lobelia chinen-sis , Chrysanthemum indicum and Buddleja officinalis show strong inhibition on Bacillus subtilis , Bacillus cereus , Staphylococcus aureus .

Objective To study the effect of conditioned media for rat bone marrow mesenchymal stem cells (BMSCs-CM) on palmitic acid (PA)-induced insulin resistance (IR) in HepG2 cells and its underlying molecular mechanisms.Methods HepG2 cells were treated with or without BMSCs-CM and L-DMEM in the presence or absence of PA.Glucose utilization in HepG2 cells were detected with PAS,glucose and glycogen measurements.Western blotting was used to assess the expression of phospho-insulin receptor substrate (p-IRS),phosphatidylinositol 3-kinase (PI3 K) and p-AKT.Results (1) Incubation of HepG2 cells with 0.25 mmol/L PA for 24 hours significantly increased the glucose concentration and decreased the glycogen content (P ＜ 0.05) in the media.(2) Treatment with BMSCs-CM significantly ameliorated the glucose and glycogen alteration in cells pretreated with PA (P ＜ 0.05),however,no obvious effect of BMSCs-CM on the cell glucose and glycogen production.(3) BMSCs-CM treatment also increased protein expression of p-IRS,PI3K and p-AKT in PA incubated HapG2 cells (P＜ 0.05).The effect of BMSCs-CM on PI3K and p-AKT expression could be mimicked upon addition of 740Y-P,a PI3K agonist,but abolished by LY294002,a PI3K specific inhibitor.Conclusions BMSCs-CM could improve the insulin sensitivity in HepG2 cells pretreated with PA through upregulation of insulin signaling component expression.

Objective To investigate the clinical value of preventive analgesia in patients with radical gastrectomy for gastric cancer.Methods The clinical data of 161 patients undergoing radical gastrectomy for gastric cancer at the Xijing Hospital from July 2012 to June 2013 were prospectively analyzed.A single-blind,randomized,controlled study was performed in the eligibe patients who were randomly divided into the preventive analgesia group and the control group based on a random number table.All the patients received major gastrectomy + Billroth Ⅱ anastomy or total gastrectomy + esophagojejunastomy,and then they received vein combined anesthesia and tracheal intubation.In the preventive analgesia group,10 mg dexamethasone and 200 mg parecoxib were administered by intravenous infusion before operation,7-8 mL ropivacaine (0.5％) were injected at the incisional site and transversus abdominis infiltration at open and close surgery and celecoxib was taken orally for 3 days.In the control group,vein analgesia pump was used after operation.The visual analogue scale (VAS),proportion of patients with postoperative out-off-bed activity time ＞ 8 hours,time of flatus,time of defecation and duration of hospital stay were recorded between the 2 groups.The measurement data with normal distribution were presented as x ± s.The comparison between groups was evaluated with the t test and repeated measures ANOVA.The data with skew distrubution and ordinal data were analyzed by the analysis of variance,and the count data were analyzed using the chi-square test.Results All the 161 patients who were screened for eligibility were randomly divided into the preventive analgesia group (87 patients) and the control group (74 patients).The scores of the VAS at postoperative day 1,2 and 3 were 2.8 ± 0.6,2.6 ± 0.4 and 1.8 ± 0.4 in the preventive analgesia group,and 5.3 ± 0.5,4.2 ± 0.6 and 2.4 ± 0.3 in the control group,with a significant difference between the 2 groups (F =4.25,P ＜ 0.05).The proportion of patients with postoperative first abmulation time ＞ 8 hours at postoperative day 1,2 and 3 were 8,17 and 20 in the preventive analgesia group,and 0,3 and 11 in the control group,with a significant difference between the 2 groups (x2 =7.60,10.26,3.16,P ＜ 0.05).The time of flatus,time of defecation and duration of hospital stay were (51 ± 24) hours,(61 ± 24) hours and (5.5 ± 3.0) days in the preventive analgesia group,compared with (71 ± 23) hours,(83 ± 30) hours and (6.3 ± 2.1) days in the control group,showing a significant difference between the 2 groups (t =5.32,5.04,0.17,P ＜ 0.05).All the patients in the 2 groups normally survived after surgery without respiratory depression,incision infection and adverse drug reaction.Conclusions Preventive analgesia in the perioperative treatment of patients with radical gastrectomy for gastric cancer could relieve the postoperative pain of patients,improve the bowel function and enhance the recovery of patients.Registry This study was registered with the Chinese Clinical Trial Registry with the registry number of ChiCTRTRC-11001440.

This study was aimed to observe bronchial asthma patients in remission after treatment of traditional Chi-nese medicine(TCM) with four diagnostic information, syndrome differentiation and changes oflung function indicators, in order to explore the efficacy evaluation with TCM characteristics. TCM tongue manifestation instrument, TCM in-quiry scale, pulse-taking instrument, acoustic diagnostic information collection system, and spirometer were used in thecollection of 33 bronchial asthma cases in remission before and after treatment (1~5 months) basedon four diagnos-tic information and lung function indexes. Single-factor analysis of variance and other methods were used in the analysis of four diagnostic parameters and lung function indexes before and after treatment. The results showed that after TCM treatment, there were significant changes on indexes such as facial complexion, tongue sub-region color, color of tongue coating and other parameters. There was significant difference in the acoustic parameters before and after treatment. After TCM treatment, the frequency of lung system symptom such as nasal obstruction was decreased. There was no significant difference on changes of pulse-taking indexes among asthma patients before and after treat-ment. After treatment, the FEV1.0% of asthma patients was increased,whichindicated that asthma ventilatory function had been improved to some extent. It was concluded that TCM objective test provide an effective basis for the diag-nosis of bronchial asthma on aspects such as TCM syndrome, disease change observation and clinical evaluation.
