1.The pressure level of nurses in Shenzhen special administrative region and its influencing factors
Chinese Journal of Practical Nursing 2008;24(12):11-13
Objective To discuss the pressure level of nurses in Shenzhen special administrative region (SAR) and its influencing factors and adopt selective psychological intervention to alleviate their working pressure,increase working efficiency and nursing quality. Methods The investigation by questionnaires was carried out by reference of working stress scale in 250 nurses and the results were analyzed.Results The main sources of working pressure include being afraid of making mistakes during work,frquent shift-work, low wages and other benefits,the character and social status of nursing work,less chances of advanced study and continuing education,lower recognition by patients,family and society.The working pressure was different in nurses with different position,time length of nursing work and education background. Conclusion Great working pressure existed in nurses in Shenzhen special administrative region(SAR).It is suggested that the management department should lessen or eliminate nurses'working pressure sourcs.Besides, they should practice measures to alleviate nurses'working pressure according to selective conditions.
2.Relationship among metastatic ratio of lymph node and pathology or its prognosis in elderly gastric cancer
Chinese Journal of Geriatrics 2015;34(10):1088-1090
Objective To study the association between metastatic ratio of lymph node and clinical pathological features and its prognosis in elderly patients with gastric cancer.Methods The first postoperative pathological data of 219 patients with gastric cancer aged ≥ 60 years were retrospectively analyzed.The relationships of metastatic ratio of lymph node with gender,differentiation degree,depth of tumor invasion,vascular invasion,perineural invasion were analyzed.We used Kaplan-Meier survival analysis and Cox regression model to analyze this relationship.Results The metastasis rate of lymph node was higher in gastric cancer patients with higher degree of differentiation,deeper tumor-infiltration,vascular invasion or neural invasion,and the metastasis rate of lymph node was increased in females than in males (all P<0.05).Kaplan-Meier survival analysis and Cox regression model analysis suggested that the metastasis rate of lymph node was an independent factor for postoperative survival rate in the elderly with gastric cancer.Conclusions The metastatic ratio of lymph node could be used to estimate the clinical prognosis of elderly gastric cancer.

Acta Nutrimenta Sinica 1956;0(03):-
Objective To study the antioxidant effects of casein peptides with different molecular weights on liver tissue in mice.Methods Forty-eight mice were divided into four groups,and fed ig casein peptides in different molecular weights,3ku and distilled water as control.Results Casein peptides could improve the antioxidation ability of the mice,as to increase glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities of liver tissue,and reduce malondialdehyde (MDA).The antioxidant enzymes activities after giving casein peptides for 30d and 15d were significantly different.Conclusions Casein peptides can enhance the antioxidation of the mice and especially more effect with the molecular weight
4.Regulation Effect of Shengmai Injection on T Helper Cells Balance in Patients with Graves Disease
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(10):-
Objective To explore the changes of Th1/Th2 cytokine in patients with Graves disease(GD) and the regulation effect of Shengmai Injection on its balance.Methods The patients with GD were randomly divided into 2 groups,the Shengmai treated group and the Methimazole treated group,30 cases per group and 30 healthy subjects were enrolled in this study.The serum concentrations of their Th1 cytokine(IFN-?) and Th2 cytokine(IL-10) were assayed by ELISA before and after treatment.Results The serum levels of INF-? and IL-10 in patients with GD were significant higher and the ratio of INF-?/IL-10 were significant lower than healthy subjects(P
5.The effect of Bay k8644 on cardiac function of myocardial ischemia-reperfusion injury in rats
Chinese Pharmacological Bulletin 2003;0(10):-
Aim To study the effect of Bay k8644 on cardiac function with the model of myocardial ischemia-reperfusion injury(MIRI)in Rats.Methods Rat MIRI was induced by occluding the left anterior descending coronary artery for 40 min followed by 90 min reperfusion.Eighteen rats were divided randomly into 3 groups: saline,Bay k8644 and 0.1% dimethyl sulfoxide(DMSO)intravenously injected 30 min after ischemia.Heart functions were assessed before ischemia and 5,20 and 40 min after initiation of ischemia and 5,30,60 and 90 min after reperfusion,by measuring heart rate(HR),the left ventricular systolic pressure(LVSP),left ventricular end diastolic pressure(LVEDP) and ?dp/dt_(max).Results After ischemia,LVSP and +dp/dt_(max) decreased(P

Objective To explore the treatment of children with hernia,and the advantage of transabdominal extraperitoneal hernia sac exclusion was analyzed.Methods A total of 102 patients in our hospital from January 2005 to January 2015 were randomly divided into 2 groups,55 cases who treated by the surgery of transabdominal extraperitoneal hernia sac exclusion were treatment group,47 cases who treated by the surgery of high ligation of the hernia sac throug the inguinal incision were control group.The operative time,length of hospital stay, length of incision,postoperative pain and hospitalization costs between two groups were compared.Results The effect of the treatment group was superior to the control group on operative time,length of incision and postoperative pain,the difference was significant(P <0.05).Con-clusion There are some advantages of more simplified operation,shorter time of the surgery,less complication,lower recurrence rate and more reliable curative effect in the treatment of transabdominal extraperitoneal hernia sac exclusion for children with hernia,which is worthy of clinical promotion.

Objective To investigate the efficacy and security of tirofiban with low-dose heparin for treating progressing stroke with intracranial vessel stenosis,to analyze the clinical value of tirofiban in the treatment of ischemic stroke.Methods Clinical data of 26 patients treated with tirofiban and low-dose heparin for progressing stroke were retrospectively collected with NIHSS increment ≥3 within 6 days of stroke as the diagnosis standard.The degree of intracranial vessel stenosis was checked by CT angiography (CTA).The efficacy of tirofiban for treating progressing stroke,and the correlation between the degree of intracranial vessel stenosis and the prognosis of progressing stroke were observed.Results The percentage of progressing stroke patients with intracranial vessel stenosis/lesion was higher than without intracranial vessel stenosis/lesion (88.5 %vs.11.5%,x2=14.786,P 0.000).There was a significant difference in NIHSS scores between progressing stroke patients with and without intracranial vessel stenosis/lesion before treatment (t 2.17,P=0.046).NIHSS scores were significantly decreased (t=3.59,P=0.021) in both two groups after treatment.MRS was lower in progressing stroke patients without intracranial vessel stenosis/lesion than in progressing stroke patients with intracranial vessel stenosis/lesion after treatment (t=6.79,P=0.001).The efficacy of tirofiban was higher in progressing stroke patients without intracranial vessel stenosis/lesion than in progressing stroke patients with intracranial vessel stenosis/lesion (60.2% vs.30.8%,x2=4.35,P<0.05).Conclusions Combination of tirofiban with low-dose heparin is safe and effective in the treatment of progressing stroke.The degree of intracranial vessel stenosis is correalted with progressing stroke prognosis.
