1.Investigation in psychological state and it's correlation factors of family members of dderly cancerpatients
Chinese Journal of Practical Nursing 2009;25(24):63-64
Objective To investigate the psychological state and its correlation factors of family members of elderly cancer patients. Methods A total of 76 family members of elderly cancer patients were investigated with questionnaires with Zung's self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Their psychological state and its correlation factors were analyzed. Results Incidence rate of anxiety of elderly cancer patients' family members was 52.63%, and incidence rate of depression was 46.05%. The mean standard score of SAS and SDS of elderly cancer patients' family members were both significantly higher than domestic norm. Difference of family member's gender, ways to pay health care fee, pain degree and disease condition led to different SAS and SDS score. Conclusions Family members of elderly cancer patients possessed different degree of psychological obstacle which related with multiple factors. Medical staff should not only think highly of patients' psychological state, but also their family members'. And meanwhile they should take corresponding strategy to reduce the incidence rate of anxiety and depression state in those family members.
2.The Effects of Diazepam on Vestibular Compensation Following Unilateral Labyrinth injury
Chinese Journal of Trauma 1990;0(03):-
This report presents two cases of unilateral acute labyrinth loss resulted from injury,each showing delay in compensation possibly due to long-term administration of diazepam.The recent literature of the effects of the drugs onyestibular compensation is reviewed.The vestibular"suppressants"property of diazepam delays compensation when used on a long-term basis.However,it might be useful in controlling vege- tative symptoms and thereby possibly facilitate compensation when used on a short- tern basis.
3.Application of insulation blanket in the esophageal cancer radical surgery
Chinese Journal of Practical Nursing 2009;25(34):36-37
Objective To discuss the application of insulation blanket in the esophageal cancer radical surgery.Methods 40 cases of esophageal carcinoma patients were divided into two groups at random,20 cases involved in the control group (non-use of insulation blankets) and 20 cases in the experimental group (use of thermal insulation blanket).The changes in body temperature of all patients were monitored with nasopharyngeal temperature probe and analyzed in statistics.Results Compared to the control group,the body temperatures of the experimental group were higher.By heating with insulation blanket,the body temperatures were increased obviously in 30 minutes after entering the operation room,but no significant difference appeared at different time points after 30 minutes.Conclusions In radical surgery of esophageal cancer,the use of blanket insulation is an effective way to maintain a constant body temperature of patients and reduce post-operative complications,and promote early recovery of patients.
4.Collagen type Ⅰ、Ⅵ and Matrix Metalloproteinase-2 in Normal and Keratoconus Corneas
Chinese Journal of Experimental Ophthalmology 2001;19(1):46-48
ObjectiveTo compare the levels and locations of metalloprotionase-2(MMP-2),collagen types Ⅰ and Ⅵ in keratoconus and normal human corneas.MethodsAn immunoperoxidase and indirect immunofluorescent technique were used to visualize the presence of collagen types Ⅰ, Ⅵ and MMP-2.The immunohistochemical staining was further analyzed and the intensity of reaction products was measured with an Image-processing system.ResultsCollagen type Ⅰ was demonstrated immunohistochemicall and indirect immunofluorescent technique in the bowman and stroma layers;collagen type Ⅵ was in epithelium basement,bowman,stroma and descement layers;MMP-2 was in epithelium,stroma and endothelium of all corneal sections.Compared with normal control specimens,the staining intensity of collagen types Ⅰ and Ⅵ was similar,while MMP-2 was markly increased.ConclusionsKeratoconus contained an increased level of MMP-2 and similar of collagen levels.These results lead further support to the hypothesis that degradation processes may be aberrant in keratoconus.
