Objective To investigate the relationship between keratinocyte growth factor (KGF), nerve growth factor(NGF)and psoriasis;and to study the interaction between keratinocytes and interstitial cells in psoriasis. Methods The expression of KGF, KGF receptor (KGFR), NGF, NGF receptor (NGFR), epidermal growth factor receptor (EGFR) and proliferating cell neuclear antigen (PCNA) was studied with immunohistochemical technique (SP) in lesional skin, non lesional skin and normal controls. Results Significant overexpression of KGF and KGFR was present in psoriatic basal cell layers and suprabasal cell layers compared to that in non lesional and normal controls (P0.05). Expression of KGF and KGFR was absent in dermis. Expression of NGF and NGFR was observed mainly in granular cell layers and upper spinous layers, and was significantly different between normal controls and non lesional, between non lesional and lesional skin (P

Objective:To investigate the relation between eotaxin, STAT6 and allergic rhinitis through comparing expressions of eotaxin and STAT6 in nasal mucosa of normal guinea pigs and of guinea pig allergic rhinitis models. Methods: Twenty-four healthy guinea pigs were equally randomized into 2 groups: normal control and allergic rhinitis models. Guinea pig allergic rhinitis models were established by the ovalbumin challenge method. Protein expressions of eotaxin and STAT6 in the nasal mucosa of the 2 groups were detected by immunohistochemical technique. Results: Expressions of eotaxin and STAT6 were found in the nasal mucosa of both normal guinea pigs and allergic rhinitis guinea pigs. Eotaxin was mostly located in the cytoplasm of the serous and mucous glands,while STAT6 mostly in the cytoplasm of subepithelial infiltrative cells.Expressions of eotaxin and STAT6 in the nasal mucosa of allergic rhinitis guinea pigs were significantly higher than those of normal guinea pigs~(P

Objective To investigate the effects of DRD1 rs265981,rs4532,rs686 and rs265976 polymorphisms on response to clozapine in resistant schizophrenic patients.Methods DRD1 genotype was determined by SNaPshot SNP technique for 154 patients with resistant schizophrenia.Clinical symptoms were evaluated by Positive and Negative Syndrome Scale (PANSS),and the responder was defined as a reduction of 50% on PANSS score from baseline after the patients were administered orally clozapine for 8 weeks.Results The frequencies of rs265981 genotypes,alleles and rs265976 genotypes had significant differences between clozapine responder group (88 cases) and nonresponder group(66 cases) in total clinical efficacy ( x2 =10.215,P =0.004 ; x2 =4.082,P =0.041 ; x2 =14.083,P =0.007 ).The frequencies of rs265976 genotypes had significant differences between clozapine response (58 cases) and nonresponse (96 cases) to negative symptom ( x2 =9.805,P =0.046).Conclusion The polymorphisms of DRD1 gene rs265981 and rs265976 may relate with clinical response to clozapine in resistant schizophrenias.rs265981 T/T,allele T and rs265976 genotype A/A are likely to be predictive factors to the improvement of total clozapine therapeutic effects.rs265976 genotype A/A are likely to be predictive factors of negative symptom with treatment of clozapine.

Objective Through the evaluation of acute myocardial infarction patients care burden of caregivers,to understand caregiver stress con?dition,and to investigate the effective predictors of acute myocardial infarction patients care burden of caregivers,so as to provide the basis for im?provement of the care burden. Methods A cross?sectional study was conducted through convenience sampling using Zarit Caregiver Burden Inter?view as the measuring tool. Questionnaires were collected by face?to?face structured interviews towards caregivers. Care burden of caregivers was eval?uated on these primary caregivers of patients with acute myocardial infarction. Results Caregivers of patients with myocardial infarction endure high care burden level. There were statistically significance among patients with different ages or revenue,the relationship of caregivers with patients,nurs?ing hours per day,psychological alignment and patients′self?care ability. Conclusion Caregivers of patients with myocardial infarction endure high care burden level. The relationship between caregivers and patients,the patient′s gender,nursing total time,nursing time every day,and the pa?tient's life self?care ability are contributed to be predictive factors. Future interventions should be strengthen on the psychological ability of the align?ment as well as measures to improve the self?care ability of the patient's life.

BACKGROUND:Short-segment pedicle screw technology has been extensively used in the treatment and repair of thoracolumbar burst fractures in the clinic. However, it requires further investigations whether bone graft through unilateral pedicle channel has superiority. <br> OBJECTIVE:To observe the perioperative effects on thoracolumbar burst fractures posterior by bone graft through unilateral pedicle channel with short pedicle screw segment fixation. <br> METHODS:Clinical data of 57 cases of thoracolumbar burst fractures without neurological symptoms treated by short segment pedicle screw internal fixation therapeutic method at the Department of Orthopedics, The First People’s Hospital of Yinchuan City from January 2009 to December 2013 were retrospectively analyzed. According to therapeutic methods, they were divided into three groups:pedicle screw fixation through injured vertebrae (n=21), unilateral pedicle screw fixation with vertebrae pedicle screw (n=19), and the short segment pedicle screw fixation with unilateral pedicle screw fixation and bone graft through pedicle channel (n=17). We observed the changes in operation time, the blood loss volume in operation, postoperative drainage blood (at the period of removing the drainage tube), injured vertebrae height’s ratio, the Cobb’s angel of injured vertebrae sagittal plane, vertebral canal encroachment rate and visual analog scale. <br> RESULTS AND CONCLUSION:(1) The unilateral pedicle screw fixation and bone graft by pedicle channel could prolong operation time and increase postoperative drainage blood volume (P<0.05). (2) Three operation methods improved vertebral body height. (3)There were no significant differences in Cobb’s angle postoperation among the three groups (P>0.05). These data suggested that the bone graft through pedicle channel was not the factors to improve the spine kyphosis. (4) Bone graft by pedical channel improved vertebrae channel value. (5) Bone graft through pedicle channel combined with screw implantation could improve pain after treatment. These findings indicated that the therapeutic technology of short pedicle screw fixation on thoracolumbar vertebral burst fracture with unilateral pedicle fixation and bone graft through pedicle channel is a safe reliable operation method.

Objective To understand the characteristics of malaria prevalence in Sichuan Province from 2012 to 2014,so as to provide evidences for improving the work of malaria elimination. Methods The epidemiological data of malaria cases in Si?chuan Province were collected from the Disease Surveillance Information Reporting System of Chinese Center for Disease Control and Prevention,and analyzed with the descriptive epidemiological method. Results A total of 690 imported malaria cases were reported in Sichuan Province from 2012 to 2014. In detail,54.49%(376/690)were falciparum malaria cases,42.03%(290/690)were vivax malaria cases,0.58%(4/690)were malariae malaria cases,1.88%(13/690)were ovale malaria cases,and 1.01%(7/690)were mixed infection cases with Plasmodium vivax and P. falciparum. Among them,five cases died. Totally 671 malaria cases were infected overseas,accounting for 97.25%of the total cases. Among which,517 patients returned from Africa and 138 patients returned from Southeast Asia. There were malaria cases reported in the whole year,and 185 cases were report?ed in May and June,accounting for 26.81%of the total cases. The cases distributed in 20 prefecture?level cities in the whole province,and there were 137 and 105 ones reported in Guangan and Chengdu,respectively,which accounted for 35.07%of the total cases. Conclusion The number of patients with overseas imported malaria in Sichuan Province increases year by year, and therefore effective measures should be carried out to control the overseas imported malaria.
