Objective To explore the application effects of PDCA circulation on behavior management in discharged patients with first cerebral infarction. Methods Patients with first attack of cerebral infarction were enrolled from the department of neurology of the First Hospital of Anhui Medical University from April 2013 to March 2015. According to their admission numbers, patients were divided into the observation group (94 cases) and the control group (80 cases). Besides of the regular personalized secondary prevention, the observation group was also applied for the PDCA cycle for nine months. Stroke Behavior Change Inventory was used to evaluate the changes of their lifestyle and medication compliance one year after discharge for two groups. Results After the observed patients were discharged one year, the changed extent of these five behaviors including quitting smoking, regular monitoring blood pressure and sugar, appropriate exercise, pressure control in the observation group were 0.00 (0.00, 3.00), 1.68 (1.00, 3.00), 1.00 (0.00, 2.00), 1.20 (0.75, 2.00), 1.00 (0.00, 1.00) points, and these in the control group were 0.00 (0.00, 1.0)0, 1.00 (0.00, 2.00), 0.00 (0.00, 1.00), 1.00 (1.00, 2.00), 0.00(0.00, 1.00) points. The observation group in these parameters had significantly higher than the control group (Z=-3.166--2.419, P < 0.05). The changed extent of these behaviors in the medication compliance such as reducing blood glucose, blood pressure, atrial fibrillation, cardiovascular disease, and stroke prevention in the observed group were 0.00 (0.00, 0.00), 0.00 (0.00, 2.00), 0.00 (0.00, 0.00), 0.00 (0.00, 0.00), 3.00 (3.00, 3.00) points, and these in the control group were 0.00 (0.00, 0.00), 0.00 (0.00, 0.79), 0.00 (0.00, 0.00), 0.00 (0.00, 0.80), 0.00 (0.00, 1.50) points. The observation group in these parameters had significantly higher the above parameters than the control group (Z=-8.081--2.595, P<0.05). Conclusions Application of the PDCA circulation in the patients with first attack of cerebral infarction after their discharge can help them correct lifestyle and increase their medical treatment compliance, which is beneficial for secondary prevention of cerebral infarction.

Background and purpose:PTEN mutation has been found in 20%-40% of malignant gliomas.The common mutant epidermal growth factor receptor(EGFR vⅢ)was reported to coexpress in PTEN-deficient EGFR-expressing tumor.PTEN has been shown to interact directly with FAK and reduce its tyrosine phosphorylation levels to inhibit cell invasion.The invasion of glioma cells with EGFRvⅢ expression and PTEN deficiency is increased.This study was to observe whether PTEN inhibits glioma cell invasion even in the presence of strong pro-invasive signals provided by constitutive EGFR activity.Methods:U87?EGFR cells were transfected with pcDNA3.1 constructs encoding PTEN and the cells invasion levels were detected by transwell invasion assay.The expression of FAK was detected by immunoblotting.FAK expression vector was transfected into U87?EGFR-wtPTEN cells and the change of cells invasion was documented.Results:PTEN and PTEN(G129E)could inhibit cell invasion induced by EGFRvⅢ.PTEN and PTEN(G129E)could decrease the FAK phosphorylation at Tyr397.Over expression of FAK in U87?EGFR-PTEN abrogated PTEN-induced down-regulation of the phosphorylation status of FAK and rescued cell invasion.Conclusions:PTEN could inhibit cell invasion induced by EGFRvⅢ by dephosphorylating FAK.

Objective To investigate the infection situation of group A human rotavirus(HRV)among the infants and young children with diarrhea in Lanzhou city,and to observe the relation between genders and age with the viral positive rate.Methods 2 378 samples of feces in the infants and young children with diarrhea were collected in this hospital from January to December 2013.The group A HRV antigen in samples was detected by using the immunochromatographic sandwich method.The positive rates of group A HRV infection in different months were analyzed and compared with the bacterial diarrhea;the viral positive rates in different genders and ages were analyzed.Results Among 2 378 detected feces samples,the average positive rate of group A HRV was 24.1% and the highest was 39.8% during the months from October to December;the average positive rate of bacterial diarrhea was 28.2% and the highest was 38.2% during the months from July to September.The positive rate of group A HRV was 25.5% in male children patients and 22.6% in female children patients,but the difference was not statistically significant (P >0. 05).The differences in the positive rates of group A HRV among different ages had statistical significance (P <0.05).The average positive rate was highest(29.0%)in children patients aged less than 2 years old,followed by the children patients aged 2 - <4 years old,which was 21.6%.Conclusion The group A HRV has the higher infection positive rate in winter and early spring,which mainly focuses on the children patients aged less than 2 years old.

Objective To evaluate the clinical effect and safety of intravenous administration of phloroglucinol combined with delivery of ball-assisted free position in parturient women during labor.Methods One hundred and fifty-two primiparous women who were treated by vaginal delivery from June 2015 to August 2016 in Beijing Navy General Hospital were selected as the study subjects.They were given 80 mg of phloroglucinol diluted in saline injection intravenous injection.Observation group were treated with childbirth.Control group treated with traditional supine or lateral body.Results The rate of descending of the observed group was longer than that of the control group((1.09±0.22) cm/h vs.(0.83±0.15) cm/h),the first labor time,the second labor time and the total labor time of the observation group were shorter than the control group((9.57±1.71) h vs.(12.13±2.64) h,(35.75±8.68) min vs.(61.21±10.03) min,(11.34±1.96) h vs.(14.66±2.70) h),the difference between the two groups was statistically significant(t=3.611,4.204,3.307,3.456,P<0.05).While the third labor time of the control group and the observation group were (8.43±1.12) min and (7.92±0.96) min,the difference between the two groups was not statistically significant(t=1.005,P>0.05).The percentage of vaginal delivery in the observation group was 89.47%(68/76),significantly higher than that in the control group(73.68%(56/76)),the difference was statistically significant(χ2=4.514,P<0.05).The incidence of vaginal midwifery was 1.32%(1/76) and that of cesarean section was 9.21%(7/76) of observation group,significantly lower than that in control group(5.26%(4/76),21.05% (16/76)),the difference was statistically significant(χ2=5.323,4.376,P<0.05).Observation group 24 h postpartum hemorrhage was (273.12±58.23) ml,significantly less than the control group((385.42±70.13) ml),the difference between the two groups was statistically significant(t=3.744,P<0.05).The observation group had postpartum hemorrhage of 1.32%(1/76),urinary retention of 2.63%(2/76),and the percentage of neonatal asphyxia of 2.63%(2/76),were lower than that of the control group(5.26%(4/76),10.53%(8/76),9.21%(7/76)),the difference between the two groups was statistically significant(χ2=4.103,4.925,4.421,P<0.05).Conclusion The delivery of ball-assisted free-body delivery in active stage of delivery can promote natural childbirth.The medical staff should update the concept of delivery and raise awareness to encourage the use of phloroglucinol combined with free-body delivery.

Objective To investigate the relationship between serum CC10 protein and lung injury induced by mechanical ventilation.Methods Forty healthy Wistar rats of both sexes weighing 200-250 g were randomly divided into 5 groups(n=8 each):group Ⅰ control;group Ⅱ mild lung injury[VT=7 ml/kg,duration of mechanical ventilation(t):2 h];group Ⅲ moderate lung injury(VT=7 ml/kg,t=4 h);group Ⅳ severe lung injury(VT=40 ml/kg,t=2 h);group Ⅴ extremely severe lung injury(VT=40 ml/kg,t=4 h).The animals were anesthetized with intraperitoneal 10% chloral hyrdrate 3.5 ml/kg and tracheostomized.Group Ⅰ received no mechanical ventilation.The animals in group Ⅱ-Ⅴ were mechanically ventilated with air(FiO2=21%,RR=40 bpm,I:E=1:2).The animals were sacrificed at the end of mechanical ventilation.The lungs were immediately removed for microscopic examination and determination of W/D lung weight ratio.The left lung was lavaged.The CC10 protein level in broncho-alveolar lavage fluid(BALF)and serum were determined by Western blotting.The Clara cells in the bronchiolar epithelium were examined by immno-histochemistry.Results The level of CC10 protein in BALF was significantly lower in group Ⅳ and Ⅴ while the serum CC10 protein level was significantly higher in group Ⅱ-Ⅴ than in group Ⅰ.The serum CC10 protein level was positively correlated while the CC10 protein level in BALF was negatively correlated with the severity of lung injury and W/D ratio.Conclusion The serum CC10 protein is closely related to the severity of lung injury induced by mechanical ventilation.

Objective:To establish animal model on the basis of the autoimmune etiology for a subset of cases of Tourette syndrome.Methods:Blood samples were drawn from patients with TS(by DSM-IV)and were sent for further enzyme-linked immunosorbent assays(ELISA)to a laboratory.Eight serum samples with the highest concentration of anti-neural antibody were selected for TS model group,and 8 serum sampled with the lowest concentration of anti-neural antibody were selected for the control group.Osmotic mini pump filled with undiluted TS or control serum were microinfused into the rat striatum at a rate of 0.5 μl /h for 72 h.Stereotypic movements were recorded at 1 d,7 d,14 d and 21 d after microinfusion.Several categories of stereotypy including bites(teeth touching the cage,wood chips,vacuous chewing or other objects except the body),taffy pulling(raises of the forepaw to the mouth and face),self-gnawing,licking not associated with grooming,grooming,head shaking,paw shaking,rearing and episodic utterances(EU)were recorded.Results:The anti-neural antibody serum concentration used for TS model was(0.29±0.06) U/L,and that used in control group was (0.10±0.04) U/L.After infusion of TS sera,stereotypic behaviors in rats was increased significantly[(37.2±7.1) vs.(106.3±11.7),P=0.000].Significant difference were observed in stereotypies scores of TS rats compared to control rats after microinfusion[(106.3±11.7) vs.(31.2±6.2),P=0.000].Conclusion:Stereotypic behaviors are increased in rats after intrastriatal microinfusion of Tourette Syndrome sera under noninflammatory conditions.
