Objective There are various researches involved in p53 gene. The aim of this study was to investigate the relationship between histological classification of early well differentiated gastric carcinoma and gene p53 with special immunohistochemical staining. Methods Fifty excision samples of early well differentiated gastric carcinoma were fixed by formaldehyde and divided into six paraffin sections, every slice being 3 ?m thick with routine HE staining and special immunohistochemical staining. Results Of the 50 samples of early well differentiated gastric carcinoma, p53 gene staining was positive in 42.0%, in which 4 cases were gastric type carcinoma(including 2 pyloric mucosal type and 2 foveolar type) with p53 gene positivity rate 50.0%, 27 cases were intestinal type carcinoma(including 11 complete intestinal type and 16 incomplete intestinal type) with p53 gene positivity rate 44.4%, 18 cases were compound type carcinoma(11 type Ⅰ and 7 type Ⅱ) with p53 positivity rate 38.9%, and one case was unclassified type carcinoma with negative p53 staining. Conclusions There is no relationship between the histological classification of early well differentiated gastric carcinoma and the expression of p53 protein.

OBJECTIVE:To observe clinical efficacy and safety of butylphthalide in the treatment of Alzheimer’s disease (AD). METHODS:94 AD patients selected from our hospital during Jan. 2013-Jun. 2014 were divided into control group(45 cas-es)and observation group(49 cases). Control group was given routine treatment as nourishing nerve,lowering blood lipid,taking Memantine hydrochloride tablet orally 5 mg,bid. Observation group was additionally given Butylphthalide soft capsule orally 0.2 g,tid,on the basis of control group. Both groups were treated for consecutive 1 year. Clinical efficacy of 2 groups were observed, and MMSE,ADL,the levels of TNF-α,IL-1,CRP and BDNF were observed before and after treatment;the incidence of ADR was compared. RESULTS:The total effective rate of observation group was 85.71%,which was significantly higher than that of control group(66.67%),with statistical significance(P<0.05). There was no statistical significance in MMSE and ADL between 2 groups before treatment (P>0.05);those of 2 groups increased significantly after treatment,the observation group was higher than the control group,with statistical significance (P<0.05). There was no statistical significance in the levels of TNF-α,IL-1, CRP and BDNF between 2 groups before treatment(P>0.05). Above indexes of 2 groups were improved significantly after treat-ment,the observation group was better than the control group,with statistical significance(P<0.05). There was no statistical dif-ference in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Butylphthalide is effective in the treatment of AD,can improve cognitive and life skills and reduce inflammatory level with good safety.

Objective:To investigate the hepatitis C virus (HCV) infection in hemodialysis patients.Methods:One hundred and fifty hemodialysis patients were tested for HCV-RNA using a reverse transcription-polymerase chain reaction (RT-PCR) assay and for anti-HCV IgG using an enzyme-linked mmunosorbent assay (ELISA).Result:The positive rate of anti-HCV IgG was 24%.The positive rate of HCV-RNA was 26.7%;the total positive rate of HCV markers was 35.3%.Conclusion:HCV infection rate in hemodialysis patients is higher than that of general population.The first-class risk factors for HCV infection is transfusion of blood,while the cross using of dialyzer and dialysis pipe-line is also one of the risk factors.

Human resource,as the core resource of hospitals,plays a key role in maintaining the competitive advantage of the hospitals.From the perspective of system engineering,this paper closely combined the present situation of human resource management under the background of medical staff shortage with the systematic theory,and systematically analyzed the problems of medical staff shortage and human resource management in public hospitals on the basis of literature research and investigation.It constructedand analyzed the archetype of “growth upper limit” that the over load of medical staff in hibited their mental health,“growth and investment insufficiency” archetype of medical staff's human capital investment,and the “trifles” archetype of medical personnel shortage.As well,it put forward the problem-solving management strategy using the theory of systematic thinking.

Objective To study the effect of human G-coupled protein kinase 4(GRK4) A142V overexpression on angiotensin Ⅱ1 type(AT1 ) receptor and its-mediated proliferation of rat vascular smooth muscle cells .Methods We constructed a lentiviral vec-tor carrying human GRK4-EGFP gene and observed its expression in A10 cells .Expression of AT1 receptor were determined by im-munoblotting ,GRK4 activity were checked by spectrophotometry ;the linkage between GRK4 and AT1 receptor were determined by co-immunoprecipitation .[3 H] thymidine incorporation was used to detect changes of cell proliferation .Results As compared with the control cells ,A142V-transfected cells had higher GRK4 activity and higher AT1 receptor expression ;there was linkage between GRK4 and AT1 receptor ,the co-immunoprecipitation levels were lower in A142V cells .The basal levels of VSMC proliferation was higher in A142V cells ,Ang Ⅱ increased VSMC proliferation to a greater extent in A 142V cells .Conclusion GRK4 A142V ,via in-creasing GRK4 activity ,increases AT1 receptor expression and function in vascular smooth muscle cell proliferation .

Objective To explore the influence of nursing intervention on the social support and compliance of parents of severe β-Mediterranean anemia children. Methods A total of 100 cases of Mediterranean anemia children’s parents were surveyed with the Social Support Rating Scale (SSRS) and self-made compliance questionnaires, the investigation was performed before the intervention,6 months, 1 year after the intervention. Results The scores of objective support, subjective support and supporting availability after the intervention were all higher than those before intervention (F=269.04, 125.12, 243.04, all P<0.01). In the pairwise comparison tests, the ranks of objective support score and subjective support score were:1 year after intervention>6 months after intervention>before intervention (P<0.01);the score of supporting availability was lower than the scores of 6 months and 1 year after intervention (P<0.01). The compliance of blood transfusion on time and taking deferoxamine on time before and after the interventions had statistical meanings (Hc=100.40,70.53, all P<0.01). In the pairwise comparison tests, the compliance score before intervention was lower than the score after intervention (P < 0.01). Conclusions Nursing intervention can improve the social support and compliance of the parents with severe Mediterranean anemia children.

Objective To clarify the role of transmembrane protein 66(TMEM66) in intima proliferation of carotid artery induced by balloon injury in rats.Methods SD rats were randomly divided into three groups (n=10), including control group, the left carotid artery balloon injury group and injury group added with lentiviruses, respectively.Accordingly, the intima proliferation of carotid artery were detected by H/E staining;the expressions of TMEM66 in carotid artery injuried by balloon were determined by Western blot,q-PCR and immunohistochemistry, and the migration and proliferation of VSMCs were measured by scratch test and CCK8 respectively.Results Compared with control group, the expression of TMEM66 in carotid artery was obviously decreased after balloon injury (P<0.05).Most importantly, the intima proliferation of carotid artery was significantly reversed by overexpression of TMEM66 via specific lentiviruses (P<0.05).Conclusions TMEM66 is able to attenuate the intima proliferation of carotid artery after balloon injury.It could be that upregulation of TMEM66 can alleviate the migration and proliferation of VSMCs by PDGF.
