Objective To study the effect of dexmedetomidine on stress response and inflammatory reaction of patients with hysterectomy.Methods 96 patients with hysterectomy who received therapy from October 2014 to October 2016 in Jinhua traditional Chinese medicine hospital were selected.According to random number table,those patients were divided into the observation group(n=48)and the control group(n=48).Two groups were treated with total intravenous anesthesia,the observation group was treated with intravenous infusion of dexmedetomidine1μg·kg-1 before anesthesia,pump is completed within 15 minutes,then continuous injection of 0.5μg·kg-1·h-1 speed to the 30min before the end of the operation; the control group was given the same way of infusion of normal saline.The operation time,blood loss,recovery time,extubation time and length of stay were recorded,and the hanges of mean arterial pressure(MAP),heart rate(HR),hydrogen peroxide(H2O2),malondialdehyde(MDA),total antioxidant status(TAS),tumor necrosis factor(TNF)-α,interferon(IFN)-γ,interleukin(IL)-10 at T0(before anesthesia),T1(at the end of pneumoperitoneum),T2(after the end of pneumoperitoneum 30min),T3(postoperative 24h)were recorded.Results There was no significant difference between the two groups in operation time,blood loss,recovery time,extubation time and length of stay; in the control group,the MAP was significantly reduce at T1,T2 was significantly higher,the HR was significantly reduce at T1(P<0.05); there was no significant change of MAP and HR levels in the observation group at each time point; the H2O2 and MDA in the observation group were lower than that of the control group at T1,T2 and T3,and the TAS was higher than that of the control group(P<0.05); the TNF-α,IFN-γ and IL-10 in the observation group were lower than that of the control group at T1,T2 and T3(P<0.05).Conclusion Intravenous infusion of dexmedetomidine before anesthesia is well for patients with hysterectomy,it'is helpful to maintain the hemodynamic stability,and effectively alleviate the stress response,inflammation reaction,it's worth promoting.

OBJECTIVE:To investigate the consumption of drugs after the inplementation of total cost prospective payment sys-tem(PPS),and to provide reference for hospital drug cost control. METHODS:The data of prescriptions collected from 9 hospital during 2007-2014 were divided into group A,B and C according to PPS,and then summarized statistically in respects of increase rate of total consumption sum,consumption sum ratio of major category;the drug cost per time of outpatient department,emergen-cy department and inpatient department were calculated as well as consumption sum ratio of self-paid drugs;the dosage per time of drugs in blood pressure and diabetes prescription were also calculated. RESULTS:The total consumption sum of drug increased slowly after the implementation of total cost PPS;the consumption sum ratio of major category kept stable,while that of anti-infec-tive agent decreased;the emergency drug cost per time achieved a negative growth,and outpatient and inpatient drug cost per time increased slightly. The proportion of self-paid drugs was relatively stable. The dosage per time of drugs in hypertension and diabetes prescriptions was stable,too. CONCLUSIONS:Total cost PPS is useful in controlling the rapid growth of drug costs,and promote the reasonable drug use. The consumption sum of self-paid drugs are well controlled. The increase of drug cost per time in outpa-tient and inpatient should arouse the attention of the relevant departments. In addition,it has no effect on drug dosage for the pa-tients with hypertension and diabetes.

Aim To investigate the relationship between the antitumor activity of berberine and the inhibition of Wnt/?-catenin signaling pathway. Methods The antitumor activities of berberine and total alkaloids of Coptis were assessed for their ability to inhibit the proliferation and to induce apopotosis of human colon cancer lines. A well-established Tcf-4 responsive reporter was introduced into human colon cancer lines to test whether berberine and total alkaloids inhibited the ?-catenin/Tcf4 activity in these cancer cells.Results The proliferation of HCT116 and SW480 cells was inhibited substantially within the concentration ranges of 5 to 40 mg?L~(1) of berberine. 72 hours after treament both HCT116 and SW480 cells underwent apparent apopotosis as demonstrated by Hoechst 33258 staining. Total alkaloids of Coptis had similar effects to berberine when comparable concentrations of it with berberine were used.Berberine effectively and specifically inhibited the Tcf4 reporter activity, but not the positive control reporter at the same experimental conditions. Conclusion Our findings suggest that berberine may be mainly responsible for the antitumor activity of total alkaloids of Coptis and this effect may be mediated at least in part by its inhibitory effect on the Wnt/?-catenin signaling pathway, which is aberrantly activated in many types of human cancer.

Objective To investigate the value of diffusion-weighted magnetic resonance imaging (DWMRI) in gross tumor volume definition and localregional recurrence/distant metastasis prediction in nasopharyngeal carcinoma ( NPC). Methods From Jun. 2008 to Feb. 2011, each of 36 patients with or without Iocalregional recurrence and/or distant metastasis treated by intensity-modulated radiotherapy in our hospital was matched in this study. The difference of apparent diffusion coefficient ( ADC) values between these two groups was compared by t-test method. The conventional MRI and DWMRI before treatment were centrally reviewed to evaluated whether DWMRI would benefit to the definition of gross tumor volume.Results The mean ADC value were (0. 753 ±0. 091) x 10 -3 mm2/s and (0. 793 ±0. 094) x10-3 mm2/s in treatment failure group and control group, respectively ( t = - 1. 79 ,P = 0. 078) . The extension of gross tumor volume were much more outstanding in DWMRI when compared to conventional MRI. DWMRI predicted localregional recurrence more accuracy than conventional MRI in one patient . Conclusions DWMRI is help to definition of gross tumor volume. The ADC value before radiotherapy can not predict the localregional recurrence and/or distant metastasis for nasopharyngeal carcinoma.
