Objective: To observe the effect of heat-sensitive moxibustion plus psychological intervention on serum contents of substance P (SP) and 5-hydroxytryptamine (5-HT), as well as the quality of life (QOL) in patients with irritable bowel syndrome (IBS). Methods: A total of 120 IBS patients were divided into three groups by random sampling method, 40 cases in each group. The heat-sensitive moxibustion group received heat-sensitive moxibustion, the psychological intervention group received psychological intervention, while the observation group received both methods. The therapeutic efficacy was evaluated after 3 courses of treatment. Results: After treatment, the therapeutic efficacy of the observation group was better than that of the heat-sensitive moxibustion group and the psychological intervention group (P<0.01), and the heat-sensitive moxibsution group was better than the psychological intervention group (P<0.05). In comparing the bowel symptom scale (BSS), the observation group was better than the other two groups (P<0.05), and there was a significant difference between the heat-sensitive moxibustion group and the psychological intervention group (P<0.05). In the comparison of QOL, the observation group was significantly superior to the other two groups (P<0.05), and there was a significant difference between the heat-sensitive moxibustion group and psychological intervention group (P<0.05). In comparing serum SP and 5-HT, the observation group was markedly better than the other two groups (P<0.05), and there were significant differences between the heat-sensitive moxibustion group and psychological intervention group (P<0.05). The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to estimate the mental state of the three groups, revealing that the observation group was better than the heat-sensitive moxibustion group and the psychological intervention group (P<0.05), and there were significant differences between the latter two groups (P<0.05). Conclusion: Heat-sensitive moxibustion plus psychological intervention can regulate the levels of SP and 5-HT, improve BSS, SDS, SAS and QOL in treating IBS.

Objective:To investigate the modulating effects of anti-epidermal growth factor monoclonal antibody Cetux- imab(C225)on the ehemosensitivity and radiosensitivity in a Docetaxel-resistant human lung adenocarcinoma cell line SPC-A-1/doeetaxel.Methods:Radiosensitivity of SPC-A-1/docetaxel was determined by clone formation experiment and quantified by calculating the enhancement ratio(ER).The growth inhibition of SPC-A-1/docetaxel cell line caused by C225 or combination of C225 and Docetaxel in different orders was detected by MTT assay.The effect of C225 on cell cy- cle distribution and apoptosis was determined by flow cytometry.Results:C225 combined with radiation significantly de- creased the number of the cell clones than radiation alone;the D_0 values were 1.73 Gy for the former and 2.39 Gy for the latter,and the enhancement ratio was 1.38.C225 alone at concentration up to 1000?g/ml for 48h had neither cytotoxic nor eytostatie effect on SPC-A-1/docetaxel in vitro.C225 administration followed by Docetaxel significantly decreased the ICw of Docetaxel(85.2?g/ml vs 128.7?g/ml).Flow cytometry demonstrated that C225 exposure induced apoptosis of SPC-A-1/docetaxel cells in a time-dependent manner.The cell in the G_0/G_1 fraction increased from(43.80?4.46)% to (60.50?6.57)%(P

AIM To study the experimental therapeutic effects of iptakalim hydrochloride(Ipt) on hypertensive cardiac remodeling in spontaneously hypertensive rats(SHR) and stroke prone spontaneously hypertensive rats(SHRsp). METHODS SHR at the age of 12 week old were treated ig with lisinopril 12 mg?kg -1 ?d -1 or Ipt 3 mg?kg -1 ?d -1 , once a day for 30 days. Age matched Wistar rats were used as normal control. 10 week old SHRsp were treated ig with Ipt 0 25,1 0 and 4 0 mg?kg -1 , once a day for 12 weeks. Age matched Wistar rats were used as normal control. After killing animals, the effects of Ipt on hypertensive cardiac remodeling were investigated. RESULTS During the 4 week experimental period, the systolic blood pressure(SBP) and heart rates(HR) of the untreated SHR were increased progressively. Ipt 3 mg?kg -1 ?d -1 could decrease SBP effectively and inhibit the increasing tendency of HR. Ipt had no effects on hypertensive cardiac remodeling in SHR. Under the same experimental conditions, lisinopril 12 mg?kg -1 ?d -1 could decrease SBP effe-ctively and had no effects on HR. The hypertensive cardiac remodeling could be alleviated by lisinopril. During the 12 week experimental period, the SBP of the untreated SHRsp were increased progressively. Ipt 0 25,1 0 and 4 0 mg?kg -1 could decrease the SBP of SHRsp effectively. Ipt at the doses of 0 25 and 1 0 mg?kg -1 had no effects on heart rates. But in the 4th week after administration of Ipt 4 0 mg?kg -1 , significant decrease in heart rates was observed. Compared with Wistar rats, the weight of left ventricle and septum(LV+S) and the ratio of LV+S to body weight(LV+S/BW) in untreated SHRsp were elevated significantly. Ipt 0 25, 1 0 and 4 0 mg?kg -1 ?d -1 could decrease LV+S and LV+S/BW significantly. CONCLUSION Ipt could decrease SBP of SHR and SHRsp effectively. The effects of Ipt on hypertensive cardiac remodeling were related with the experimental therapeutic period. After having been treated with Ipt for 4 weeks, the hypertensive cardiac remodeling could not be reversed. But after having been treated with Ipt for 12 weeks, the hypertensive cardiac remodeling could be reversed significantly.

Objective To evaluate the technique of treating severe tuberculous peritonitis complicated with intestinal obstruction. Method Clinical data covering 44 cases from Jan. 1994 to Dec. 2004 were analyzed retrospectively. All the 44 cases were suffering from severe tuberculous peritonitis complicated with intestinal obstruction for a long time. Among them 36 cases were diagnosed pre-operatively and 8 cases were confirmed post-operatively. All the patients underwent laparotomy, and all intestinal adhesions were divided, then the intestine loops were regularly aligned. Result 43 cases were cured, 2 patients developed postoperative intestinal fistula, and one patient died. Conclusion No curative effect could be obtained if medical treatment only was given for tuberculous peritonitis complicated with complete intestinal obstruction. The present surgical technique offers a better chance to relieve intestinal obstruction as a reult of tuberculous peritonitis.

AIM To investigate the effects of iptakalim hydrochloride(Ipt) on the association and dissociation kinetic processes of [ 3H]glibenclamide(Gli) binding with sulfonylurea receptor(SUR 2B ) of ATP sensitive potassium channel (K ATP ) in vascular smooth muscles derived from Wistar rats,and to compare the properties of Ipt with those of nucleotides. The interactions between Ipt and nucleotides were also determined. METHODS The experiments of the association and dissociation kinetic processes of K ATP blocker[ 3H]Gli binding with endothelium denuded aorta smooth muscles were used. RESRLTS (1)The specific bindings of[ 3H]Gli with SUR 2B were not displaced by Ipt at the concentrations of 10 pmol?L -1 ～ 0 5 mmol?L 1 . Ipt 100 ?mol?L -1 retarded the association kinetic process and accelerated the dissociation kinetic process of [ 3H]Gli binding with SUR 2B . (2)Opposite to Ipt, ATP 1 mmol?L -1 accelerated the association kinetic process and retarded the dissociation kinetic process of [ 3H]Gli binding with SUR 2B There was an interaction between ATP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B . (3) Similar with Ipt, ADP 1 mmol?L -1 retarded the association kinetic process and accelerated the dissociation kinetic process of [ 3H]Gli binding with SUR 2B , there was an interaction between ADP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B . (4)Different from ATP and ADP, UDP had no effect on the association and dissociation kinetic process of [ 3H]Gli binding with SUR 2B . And there was not interaction between UDP and Ipt. CONCLUSION Ipt had no affinity with the binding sites of K ATP blocker in SUR 2B , but had negative allosterical modulation on it. The modulatory properties of Ipt were opposite to those of ATP, similar with those of ADP and different from those of UDP. There were interactions between ATP, ADP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B , but there was not interaction between UDP and Ipt.

OBJECTIVETo investigate the apoptosis and proliferation effect of matrine on human medulloblastoma cell line D341 in vitro and the effect of the expression of the related caspase 3 and caspase 9 proteins.

METHODSThe D341 cells were cultivated successfully in vitro. Then the cells were divided into 5 groups according to the concentration of matrine (0.5 mg/mI group, 1.0 mg/ml group, 1.5 mg/ml group, 2.0 mg/ml group and the control group was 0 mg/ml). All the experiments were repeated three times. The cell morphologic and structure change was observed with the optical microscope and the transmission electron microscope. The proliferation of D341 cell was analyzed using Cell Counting Kit-8 assay. Apoptosis was detected by Annexin V-FITC/PI double staining. The expression of Caspase3 and Caspase9 was detected by Western blot.

RESULTSWith the effect of matrine, the proliferation inhibition rate gradually increased with drug concentrations increasing, and there was a significant difference (P < 0.01). The inhibitory effect of matrine on cell proliferation was different with the different treatment time, there was a significant difference between the 24 h to 72 h groups (P < 0.01). The apoptotic rate increased with matrine concentrations increasing. There were significant differences between the group of 0.5 mg/mI or 1.0 mg/mI to the group of 1.5 mg/mI or 2.0 mg/mI (P < 0.05). The apoptotic rate increased with the prolonged treatment time. There were significant differences between the group of 24 h or 48 h to the group of 72 h ( P < 0.05). With the increase of matrine concentration, the expression of Caspase 3 and Caspase 9 increased (P < 0.01).

CONCLUSIONMatrine induces the apoptosis, and inhibits the proliferation of human medulloblastoma D341 cells in vitro by up-regulation of the expression level of Caspase3, Caspase9.
