This article explains four cases of professor REN Ji-xue,including anasarca,serious blepharoptosis,head cold,summer diarrhea,from which we can find the laws of syndrome differentiation by him. In which,the key point of the pathogenesis of anasarca is spleen-qi deficiency, so replenishing qi and invigorating the spleen, warming yang for diuresis are the treatment nethod for anasarca. Sinking of qi due to deficiency of spleen leads to serious blepharoptosis and Invigorating Spleen and Replenishing Qi Decoction is the main prescription. The key pathogenesis of head cold is disharmony of nutrient qi with defensive qi, so regulating ying and wei, dispersing lung qi for resuscitation are the treatment methods, and both inside and outside therapies are in use. Cold-damp invasion of spleen is the main cause of summer diarrhea, so activating qi flowing and warming spleen and stomach, dissipating dampness for stopping diarrhea are used. Professor REN Ji-xue is good at taking different method according to different key point of the pathogenesis, so the efficiency is good. This is one feature of Professor REN in treating miscellaneous diseases.

Objective To identify and characterize the CD34~+ stem cells of hematopoietic tumor cell lines. Methods Taking CD34 molecule as a marker to identify if there are CD34~+ tumor cells in hematopoietic tumor cell lines(THP-1,MEL,K562,MOLT-4,RAJI,RPMI8226,SP2/0 and DCS) by fluorescence staining and FCM technology. We separated CD34~+ cells from K562 and MOLT-4 for further study.CD34~+ cells were cultured and observed their development.CD34~+ and CD34 +- cells were compared in their functional status(mRNA),cell cycles(G -0/G -1),their degree of differentiation(Id-1 expression) and their multi-drug resistance(gp expression). Results The percentages of CD34~+ cells were 6 ^2%(DCS),5.2%(MEL),1.4%(RAJI),2.5%(THP-1),2.1%(MOLT-4),3.1%(K562),0(SP2/0),and 0(RPMI8226) respectively.After culturing CD34 ++ cells isolated from K562 cells line could proliferate and the percentage of CD34 ++ reminded the same.CD34 ++ tumor cells contained much less RNA,more G0/G1 cells,expressed more Id-1 protein(less differentiated state) and possessed more P-gp(stronger multi-drug resistance).Conclusion There exists a very small portion of CD34 ++ stem cells among hematopoietic tumor cells and these cells are in a more primitive state.

Objective:To observe apical sealing ability of two kinds of nanomaterial. Methods:40 straight human maxillary anterior teeth were randomly divided into four experimental groups of 8 samples each and two control groups of 4 samples each. The root canals were prepared using step-back technique and obturated with gutta-percha and one of the sealers by the lateral condensation technique. Group 1: Filled with zinc oxide-eugenol sealer and gutta-percha (ZOE); group 2: Filled with hydroxyapatite sealer and gutta-percha (HA); group 3: Filled with nano-zinc-oxide sealer and gutta-percha (NZO); group 4: Filled with nanohydroxyapatite sealer and gutta-percha (NHA). The teeth were placed into microleakage model. Glucose leakage from the coronal to apical was measured by the concentration of glucose in apical reservoir at 1, 2, 4, 7, 10, 15, 20, 25 and 30 days with GOD (glucose oxidase ) method. The apical sealing ability of the materials were assessed according to the concentration of glucose leakage. Results:The glucose leakage of four kinds of materials differed significantly (P

Objective To evaluate the curative effects of venlafaxine in patients with depressive disorder between therapeutic modes of inpatient and outpatient. Methods Seventy-two patients with depressive disorder including 36 inpatients and 36 outpatients were measured respectively with HAMD24 after treatment for 1 week, 2 weeks, 4 weeks and 8 weeks, and then the curative effects were compared between two groups. Results It was found that all patients in the inpatient group completed the observation and two patients in the outpatient group didn’t complete the observation. The HAMD24 score was significantly decreased in the inpatient group than that of the outpatient group from the second week to the end of the eighth week (P<0.05). The total effective rates were 80.6% for inpatient group and 64.7% for outpatient group, no significant difference between them. Conclusion Venlafaxine shows a higher therapeutic value and outcome in the therapeutic mode of inpatient.

Objective To discuss the barriers influencing the application of evidence-based nursing. Methods Nine hundred nurses from August 2013 to February 2014 were selected from five polyclinics in Shenzhen by randomly cluster sampling according to different departments and wards. We carried out the survey with the Chinese version of cognitive of impairment of nursing scientific research scale. Results The sores of 4 dimesions of scientific application of evidence-based nursing from high to low were effectiveness and system of research, resource to evidence-based nursing, quality of research and attitude and ability of nursing staff. The main barriers in applying scientific research payoffs by the nursing staff included the deficient resource and equipment provided by hospitals (68.09%), the jumbled medical development information confused the nurses in selecting related reference (66.75%), failing to put the scientific achievements into practice (66.01%),insufficient time to actualize new ideas (64.15%), and difficulty in obtaining the reference of scientific research (64.04%). Conclusion The barriers to scientrfic application of evidence-based nursing were the deficient resource and time and difficulties to find evidence. The nursing policy makers should adopt efficient measures aimed at the difficulties the nursing staff in applying their research results, thereby popularize the application of research achievements in hospitals.

OBJECTIVE:To investigate the effects of etomidate combined with propofol on painless gastrointestinal endoscopy and cognitive function of elderly patients. METHODS:Totally 90 elderly patients with painless gastrointestinal endoscopy were ran-domly divided into propofol group(30 cases),etomidate group(30 cases)and combination group(30 cases). Propofol group was given Fentanyl injection 1 μg/kg+Propofol injection 1.5 mg/kg;etomidate group was given Fentanyl injection 1 μg/kg+Etomidate injection 0.3 mg/kg;combination group was given Fentanyl injection 1 μg/kg+Propofol injection 1 mg/kg+Etomidate injection 0.15 mg/kg. The levels of SBP,DBP,HR,MAP and SpO2 at different time points,examination time,anesthesia induction time,recov-ery time and recovery time of orientation were observed in 3 groups. NCSE and MMSE score at different time points,the occur-rence of ADR were also observed in 3 groups. RESULTS:During examination,SBP,DBP,MAP and SpO2 of propofol group were significantly lower than before anesthesia,after examination and those of combination group,with statistical significance(P<0.05);but there was no statistical significance in above indexes of propofol group between during examination and before anesthesia (P>0.05). The recovery time and recovery time of orientation in combination group were significantly shorter than propofol group and etomidate group,with statistical significance(P<0.05),but there was no statistical significance in above indexes between etomidate group and propofol group(P>0.05). The proportion of patients'memory ability,computing ability,orientation ability passing examination in combination group were significantly higher than propofol group,with statistical significance(P<0.05). There was no statistical significance in above indexes between combination group and etomidate group,between etomidate group and propofol group(P>0.05). There was no statistical significance in MMSE score of combination group at different time points (P>0.05);MMSE score of propofol group 15,30 min after anesthesia and that of etomidate group 15 min after anesthesia were significantly lower before anesthesia and combination group,with statistical significance(P<0.05). There was no statistical signifi-cance in MMSE score of propofol group 1 h after anesthesia,etomidate group 30 min and 1 h after anesthesia,compared to before anesthesia(P>0.05). The incidence of apnea,hypotension and injection pain in combination group and etomidate group were low-er than propofol group,the motor response,myoclonus,nausea and vomiting in combination group and propofol group were lower than etomidate group,the tachycardia ease in combination group was lower than propofol group,with statistical significance(P<0.05). CONCLUSIONS:Etomidate combined with propofol anesthesia shows good therapeutic efficacy for painless gastrointestinal endoscopy of elderly patient,can reduce cognitive dysfunction and shortens recovery time,but doesn't increase the occurrence of ADR.
