Objective To explore the effects ofDoctor-nurse Integratingmode on the operation room nursing quality improvement. Methods From July 2014 to Dec. 2014,11 423 operations in our hospital were chosen as control group,while 10 897 operations from Jan. 2015 to June 2015 as intervention group.An administrating group of Doctor-nurse Integrating mode was formed, with both doctors and nurses acting as quality controllers. A144 Regular Meetings System was also formed. The author retrospected and analyzed 11 423 negative accidents which occurred during operation. Management details and responsibilities were specified, and training was enhanced. All these were monitored, controlled, implemented and improved by operation doctors, anaesthesia doctors and operation room nurses. Results The rate of negative accidents dropped from 1.226%(140/11 423) to 0.340%(37/10 897) since the implementation of Doctor-nurse Integrating mode of operation quality control. Conclusions Doctor-nurse Integrating mode of operation quality control has positive effects on the improvement of operation nursing quality.

Study of depression and antidepressant drugs mainly depends on animal models. Twelve animal models of depression related to some sets of validating criteria are reviewed. Of the 12 models, some traditional models (reserpine reversal, amphetamine potentiation) are rejected as they are devoid of selectivity, insufficient to predict antidepressant activity in the compounds tested. The models with the highest overall validity are the intracranial self-stimulation, chronic stress and learned helplessness models in rats, and the primate separation model. A combination of several models may be the best way to study depression and to screen antidepressant drugs. This combination can be used to detect compounds comparable to those antidepressants possessing clinically established antidepressant activity.

AIM:The different effect of bivalent immunoglobulin Yolk(IgY) was evaluated against snake venom between intragastric administration and intraperitoneal injection in mice with cobra or viper envenomation.METHODS:The venom of naja and viper was injected alternately into the leghorn hen.Bivalent anti-snake venom IgY was extracted by water dilution.The concentration of bivalent IgY in plasma was observed in indirect ELISA assay after bivalent anti-snake venom IgY taken orally.The gastric emptying function test was used for determining optimization time after gastric administration of IgY.The protective effect of bivalent anti-snake venom IgY was compared between intragastric administration and intraperitoneal injection in mice with cobra or viper envenomation.RESULTS:Bivalent anti-snake venom IgY was extracted from eggs laid in 28-42 d after the first immunization.The titers of Bivalent IgY against cobra and viper venom were 1:12 800 and 1:6 400.At the time of 2.5-3.5 h after bivalent anti-snake venom IgY was taken orally in three concentrations(75 mg,150 mg,300 mg?0.5 mL-1?20 g-1 BW),the gastric evacuation rate of mice was above 68.9%,with the plasma concentration of bivalent IgY in peak.The survival time of mice envenomation with snake venom was extremely prolonged(P

OBJECTIVE: To determine the protective effects of nourishing spleen yin recipe (Zibu Piyin Recipe, ZBPYR), a compound traditional Chinese herbal medicine, on endoplasmic reticulum (ER) in neuronal cells responding to the stress by using sero-pharmacological method. METHODS: The mouse neuroblastoma cell line Neuro2a cells were treated with tunicamycin (Tm, an inhibitor of N-glycosylation). The ZBPYR-treated cell group was established by incubating cells with ZBPYR serum for one hour and treated with Tm. Reverse transcriptase PCR (RT-PCR) was utilized to detect the mRNA expressions from two genes after treatments, ER molecular chaperone glucose regulated protein 78 (GRP78) and transcriptional factor CCAAT/ enhancer-binding protein-homologous protein (CHOP). Lactate dehydrogenase (LDH) assay was also carried out to determine the LDH leakage from Neuro2a cells after treated with Tm and staurosporine (STS). RESULTS: The ZBPYR-treated cell group at all tested ZBPYR dosages showed significantly reduced expressions of both genes compared with Tm (5 microg/ml) treated control group (P<0.05). Therefore, ZBPYR serum inhibited the expressions of GRP78 and CHOP in mRNA level under ER stress induced by Tm. Different concentrations of ZBPYR serum pretreatment reduced the LDH leakage compared with the Tm and STS groups (P<0.05). Therefore, ZBPYR serum may inhibit the LDH leakage induced by Tm and STS. CONCLUSION: ZBPYR has neuroprotective effects. The mechanisms may be associated with inhibition of ER stress and mitochondrial dysfunction.

BACKGROUND:The functions of homo heterogeneous ribonucleoprotein E1 are very wide. It can participate in the expression of skeleton proteins in the nervous system. OBJECTIVE:To construct the recombinant plasmid of homo heterogeneous ribonucleoprotein E1 and observe its expression in nerve cells for further studying the functions of it in neurocytes. METHODS:Using pcDNATM4/His C, the homo heterogeneous ribonucleoprotein E1 was subcloned into recombinant plasmid E1-pcDNATM 4/His C, fol owed by enzyming and sequencing. After SH-SY5Y cells were transfected with the recombinant plasmid, western blot analysis and real time RT-PCR were used to detect the expression of homo heterogeneous ribonucleoprotein E1 in SH-SY5Y cells. And the growth of SH-SY5Y cells was observed. RESULTS AND CONCLUSION:We successful y constructed the eukaryotic expressed vector of homo heterogeneous ribonucleoprotein E1. The recombinant plasmids were verified to express in SH-SY5Y cells correctly at mRNA and protein levels. And SH-SY5Y cells generated quickly after homo heterogeneous ribonucleoprotein E1 was over-expressed. The homo heterogeneous ribonucleoprotein E1 is an important protein in neural development. And this vector offers the premise for further studying its function in nervous system.

Five general practitioners were trained for application of the enhancing CalgaryCambridge guide in consultation.The consultation time in 50 patients were recorded before and after training and the satisfaction degree of patients was investigated by questionnaire survey.Results showed that the length of consultation time after training was longer than that before training (490 s vs 277 s,P ＜ 0.05) and also longer than that of specialists (490 s vs 268 s,P ＜0.05).The overall satisfaction rate of patients was increased after training (72％ vs 88％,P ＜0.05).The results indicate that training of Calgary-Cambridge guide for doctor-patient communication can improve the communication skills of general practitioners.
