A growing body of research concerns about the mental psychological intervention involved in the treatment of chronic pain. It still continue reported that combining with mental psychological intervention in pain management could relieve pain level, therefore improve quality of lives. Common psychological intervention including psychological and pharmacological approach and psychological behavior approach both support their efficacy

Objective:To compare the effects of Zn~(2+)onthe P2X receptor-mediated,ATP-induced currents in neurons separated from rat superior cervical ganglion(SCG),nodose ganglion(NG),and otic ganglion(OTG).Methods: Whole-cell patch clamp recording technique was used to study the regulatory effects of Zn~(2+) on ATP/??-me ATP-induced currents in the above 3 ganlglion neurons.Results: All SCG neurons responded to ATP with a sustained current,while no neurons responded to ??-me ATP;Zn~(2+) potentiated ATP-induced sustained currents to(1 442?34)% of the original value.All NG neurons responded to ATP and ??-me ATP with a similar sustained current;coapplication of Zn~(2+)(10 ?mol/L) potentiated their responses to(180?12)% and(262?28)%,respectively.All OTG neurons responded to both ATP and ??-me ATP with a sustained current.Coapplication of Zn~(2+)(10 ? mol/L) did not significantly potentiate the sustained currents induced by 10 ?mol/L ATP,but when ATP was at 30 ?mol/L,Zn~(2+)(10-100 ?mol/L) inhibited ATP-induced sustained currents in a dose dependent manner.If TNP-ATP(100 nmol/L) was first used to inhibit ATP-induced current to(26?2)% of the original value,Zn~(2+) at 10 ?mol/L potentiated the inhibited current to(127?9)% of its original value.Coapplication of Zn~(2+)(10 ?mol/L) potentiated ??-me ATP-induced currents to(146?5)% of the control.Zn~(2+)(300 ?mol/L) had no effect on ?_(on) and ?_(off) of ATP-and ??-me ATP-induced(30 ?mol/L) currents in OTG neurons.Conclusion:(1) Zn~(2+) is an allosteric modulator of P2X_(2) and P2X_(2/3) receptors in SCG and NG neurons and can potentiate the currents they induced.(2)The predominant receptor subtypes in OTG appear to be homomeric P2X_(2/3) and a little P2X_(2).Zn~(2+) has an inhibitory effect on the ATP-induced currents in OTG neurons,suggesting some novel members of the P2X purinoceptor exist in these neurons.

Objective To explore the clinical significance of interstitial chemotherapy applied in breast cancer.Methods Sixty breast cancer patients with modified radical mastectomy were divided into treatment group (40 cases) and control group (20 cases) according to whether using fluorouracil implants.The control group was given conventional treatment.In treatment group,distilled water washed the wound after conventional treatment,and fluorouracil implants (0.4 g) was placed below local tumor,between pectoralis major and pectoralis minor,below 0.5 cm axillary vessel.The bone marrow suppression,liver and renal function,gastrointestinal reaction,skin flap necrosis,subcutaeous hydrops,local recurrence were observed in the 2 groups.Results There were no significant differences in the rates of bone marrow suppression,liver and renal function abnormal,skin flap necrosis,subcutaeous hydrops and gastrointestinal reaction between treatment group and control group (P ＞ 0.05).The rate of local recurrence in treatment group was significantly lower than that in control group [0 vs.20.0％ (4/20)],there was statistical difference (P ＜0.05).Conclusion Intraoperative application of fluorouracil implants is safe and effective in modified radical mastectomy of breast cancer.

Objective To investigate the carriage and homology of carbapenemase genes of multidrug-resistant Acinetobacterbaumannii (MDRAB)in Wujiang area.Methods A total of 44 non-duplicated MDRAB isolated from patients in 3 general hospitals in Wujiang area from January 2010 to December 2013 were collected. Minimum inhibitory concentrations (MICs)were detected,carbapenemase genes OXA-51,OXA-23,OXA-24,OXA-58, IMP,TEM,SHV,and GES were amplified with polymerase chain reaction(PCR),homology of strains was detec-ted with pulsed-field gel electrophoresis (PFGE).Results 44 MDRAB strains were mainly collected from sputum (93.18% ),mainly distributed in intensive care unit (ICU),department of respiratory diseases,and department of neurosurgery,accounting for 45.45% ,27.27% ,and 13.64% respectively;MDRAB were both sensitive to minocy-cline and polymyxin B,resistance rates to piperacillin,ampicillin/sulbactam,ceftazidime,gentamicin,amikacin, and ciprofloxacin were all 100.00% ,resistance rates to imipenem and meropenem were both 97.73% . 44 MDRAB strains were all detected OXA-51,OXA-23 and TEM genes,12 strains were positive for GES gene,1 strain was positive for OXA-58 and SHV respectively,OXA-24 and IMP genes were not found ;MDRAB were divided into 7 types of G-A,which included 19,3,9,3,1,4,and 5 strains respectively,type A was mainly from two large gen-eral hospitals in Wujiang area (Wujiang First People’s Hospital and Shengze Hospital),type B,D and E strains were not detected in Wujiang First People’s Hospital,type E strain was only 1 isolate and was from Yongding Hos-pital,the other types were sporadically distributed.Conclusion Multidrug resistance of clinically isolated Acineto-bacterbaumannii is serious in Wujiang area,OXA-23 and TEM genes are major causes of multidrug resistance in Acinetobacterbaumannii,the main types are A and C,which present clonal spread.

Objective In the present study, we observed the distribution of nitric oxide synthase positive neurons in the developing rat telencephalon and to realize the possible roles of NO in brain development further. Methods NADPH-d histochemical method was used to investigate the micromorphology and distribution of NOS positive neurons in rat telencephalon from embryonic day 14 (El4) to postnatal day 14 (P14). Results At El4, no neurons stained. Labeling was observed in the ventrolateral of the striatum at E15. At E17, positive neurons were seen in the cerebral cortex and piriform cortex. They were cells with small cell bodies, shorter dendrites and less ramification. The stained neurons were either increased or maintained in both number of neurons and intensity during development. At E20, positive cells were found in many regions. Many positive neurons were present in the piriform cortex, ventrolateral of the striatum and bed nucleus of the stria terminalis. They acquired larger size and more complex dendrites. After birth, intensely stained NOS positive fibers were distributed widely in the cerebral cortex and striatum. Stained cells were found in the corpus callosum and hippocampus also. The distribution pattern of positive cells at P14 was essentially similar to that reported in adult rats. Conclusion The distinctive temporal and spatial expression pattern of nitric oxide synthase positive neurons in the telencephalon indicated that NO may play an important role in brain development and maturation.

A good linear range of alacyclovir was 0. 2-50μg·ml-1(r=1. 000 0), and the average recovery was 99. 3%(RSD=0. 6%, n=9). The content of the tablets from two pharmaceutical companies was 92. 7% and 97. 4%, respectively, that of acyclovir calculated by an external standard method was 0. 5% and 0. 4%, respectively, and that of D-valacyclovir calculated by a self-control method was 0. 9%.
