Objective To observe the clinical effect of penehyclidine hydrochloride(Changtuoning)combined with atropine in treatment of patients with severe acute organophosphorus poisoning(AOPP). Methods The clinical data of 64 patients with severe AOPP admitted into Taizhou Municipal Hospital in Zhejiang Province and Quannan County People's Hospital in Jiangxi Province from January 2004 to September 2012 were retrospectively analyzed. Patients were divided into penehyclidine hydrochloride and atropine combined group(PH-A group,32 cases)and atropine treatment group(32 cases)depending on the difference in selection and application method of anticholinergic drugs. The application of anticholinergic drugs,length of mechanical ventilation,70%cholinesterase (ChE)activity recovery time,length of stay in hospital,incidence of complications,and cure rate were compared between the two groups. Results Compared with atropine treament group,the total usage of atropine in PH-A group was significantly decreased(mg:35.39±45.76 vs. 105.46±139.87,P<0.05),the length of mechanical ventilation (days:5.3±4.2 vs. 7.8±6.8,P<0.05),70%ChE activity recovery time(days:8.2±3.8 vs. 11.0±5.4,P<0.05), and length of stay in hospital(days:12.0±3.8 vs. 14.6±5.3,P<0.05)were significantly shortened in PH-A group, and the overall incidence of complications were significantly lowered in PH-A group〔68.75 %(22/32)vs. 93.75%(30/32),P<0.05〕. The difference in cure rate between the combined group and atropine treatment group was not statistically significant〔96.87%(31/32)vs. 90.62%(29/32),P>0.05〕. Conclusion Penehyclidine hydroehloride combined with atropine in the treatment of severe AOPP can significantly improve the therapeutic efficacy,reduce the incidence of complications and length of stay in hospital.

Objective To explore effects of hcmoperfusion on toxic ingredients in plasma of rabbiis with a-cute intoxication of Radix Aconiti Kusmezoffii Monkshood.Method Sixteen male Japanese Giant Ear Rabbits were randomly divided into acute poisoning(AP)group and acute poisoning + hemoperfusion(AH)group(8 an-hnals in each group).Acute poisoning models were established in rabbits of both groups with intragastric adminis-tration of Radix Aconiti Kusmezoffii Monkshood liquid in dose of 1 mL/kg in order to produce arrhythm which oc-curred within ode hour after intragastric administration was regarded as the criteria of successful animal model.and then hemoperfusion with active carbon was performed for 2 hours in AH group.The pathological chanses of brain,myocardium and hepatic tissues were observed.The plasma concentrations of toxicants including mesaconitine,a-conitine and hypaconitine were measured by using HPLC-MS at 1 h,2 h,3 h,and 6 h after poisoning.Student's T test was used to identify the significance.Results The brain.myocardium and hepatic tissues of the rabbits in AP group showed hyperemia and edema which were attenuated after hemoperfusion.The plasma concentrations of mesaconitine,aconitine and hypaconitine revealed no significant differences between AP group and AH group with-in one hour after poisoning(P＞0.05),while at 2 h and 3 h after poisoning,the plasma concentrations of mesaconitine were(2.11±1.08)ng/mL,(2.02±1.46)ng/mL,respectively,aconitine(39.70±9.31)ng/mL,(19.71±16.06)ng/mL,respectively,and hypaconitine(1.70±0.71)ng/mL,(2.12±1.33)ng/mL,respec-fively in AH group,and they were significantly lower than those in AP group(P＜0.05).Conclusions The the plasma concentrations of mesaconitine,aconitine and hypaconitine were lower and the histopathological changes were attenuated after hemoperfusion.Hemoperfusion is a good intervention for acute intoxication of Radix Aconiti Kusmezoffii Monkshood.

[Objective] Examine the expression of Galectin-3 (Gal-3),B cell lymphoma-2 protein (Bcl-2) in epithelial ovarian cancer tissues with regard to clinicopathological and survival variables,testing whether they can serve as prognostic markers and provide evidence for further research.[Methods] 98 EOC tissues and 10 normal ovarian tissues were collected,as well as their clinical documents.The expression of Gal-3 and Bcl-2 was tested via immunohistochemical staining analysis.Then the correlation between these two proteins and the clinicopathological and survival variables of these patients were evaluated.[Results] Of the 98 EOC,Gal-3 and Bcl-2 were all cytoplasmic staining.Gal-3 was observed in a majority of the EOC tumor cell proper (75/98,76.5％) but not in normal ovarian tissues.Bcl-2 was observed in a majority of the EOC tumor cell proper (50/98,51.0％) but not in normal ovarian tissue.Spearman bivariate correlation test show that there was no correlation between the expression Gal-3 and Bcl-2 (P =0.867).Gal-3 expression in EOC was associated with histology and platinum sensitivity (P =0.043,P =0.038),while Bcl-2 was associated with FIGO stage (P =0.029).Cox univariate analysis revealed that Gal-3,Bcl-2 expression,platinum sensitivity,stage were associated with overall survival (P =0.008,P =0.021,P ＜ 0.001,P ＜ 0.001).Further multivariate analysis showed that only Gal-3 expression,platinum sensitivity,stage affected the survival of these patients (P =0.014,P =0.021,P ＜ 0.001).[Conclusions]The expression of Gal-3 and Bcl-2 in EOC was significantly higher than that in normal ovarian tissue,supposed that they may involve in the development and progression of EOC.Gal-3 expression was associated with histology,platinum sensitivity and survival,it may be an independent predictive factor for EOC prognosis.There was no correlation between the expression Gal-3 and Bcl-2 in EOC,the functional mechanism between these two protein need further research.
