Objective To evaluate the effect of using pre-warning intervention in the course of nursing patients who have accepted the cardiac operation under direct vision. Methods Using pre-warning intervention in 736 patients who have accepted the intracardiac surgery under extracorporeal circulation. Results There were not patients have aucte bed sore after using the pre-warning intervention. Conclusion Using pre-warning intervention can prevent the acute bed sore effectively among the preoperative patients,and then reduce the unnecessary dissension between nurses and patients,improve the quality of nursing and the patients′ satisfaction.

Objective To investigate the potential and early effect of hypertonic saline resuscitation on Tlymphocyte subpopulations in patients with traumatically hemorrhagic shock.Method Eighty-two patients with acute traumatically hemorrhagic shock admitted from Department of Emergency，Beijing Tongren Hospital，from De cember 2006 to July 2008 were randomly divided into：hypotonic saline(HS)group(n=43)and Lactated Ringer's solution(LR)group(n=39).The criteria of eligible patients were systolic blood pressure＜90mm Hg at admission with definite evidence of blood loss.Patients with immune system diseases and those who died within 24 hours of admission were excluded.Patients in HS group received intravenous administration of 200 mL of 7.5% sodium chloride withhin 15～20 minutes，and LR group received routine therapy with Lactated Ringer's solution.Blood pressure and heart rate were recorded 10，20，and 60 minutes after the start of resuscitation and compared between two groups.Before and 24 hours after treatment，peripheral blood levels of T-lymphocyte subpopulations including CD3+，CD4+，and CD8+ were measured by using direct immunofluorescence test and compared between two groups.The inter-group comparison was carried out by using independent sample t-lest and intragroup comparison using paired t-test.The numabers of operation，complication cases and death cases were conducted by using X2 test.SPAS version 11.0 software was used for statistical analysis.Results The volume of solution infused in HS group was(3820±623)mL and in LR group was(5430±1254)mL(P＜0.05).At 10 and 20 minutes after the sdministration of solution.the mean blood pressures in HS group were both significantly higher than those in LR group(P＜0.01).The levels of CD3+and CD4+lymphocytes in peripheral blood in HS group 24 hours after treatment were sinificantly higher than those in LR group(P＜0.01).Totally，63(76.8%)patients were cured and 19(23.2%)patients died.ARDS occurred in 10 patients and MODS occurred in 14 patiellts.The mortality，and the rates of ARDS and MODS in HS group were sinificantly higher than those in LP group(P＜0.05).Conclusiom In patients with acute traumatically hemorrhagic shock.HS can increase the effective circulating vol. ume，ameliorate the perfusion of tissues and organs，improve the immune fuction of T-lymphocytes，decrease the rats of ABDS and MODS，mad decrease the morality.HS is more effective than routine solution used for resuscitation.

Objective To measure the tear film lipid layer thickness (LLT) in dry eye patients and investigate the correlations of LLT with ocular surface signs.Methods One hundred and thirty dry eye patients (130 eyes),including 64 meibomian gland dysfunction (MGD) patients and 66 non-MGD patients,were included in this study.LLT,break-up time (BUT),fluorescein staining (FL),Marx's line (ML) score and Schirmer I test were performed and examined.The distribution of LLT in different age groups and the correlations between LLT and other examinations were analyzed.Results There was significant difference in LLT among different age groups (P =0.007),while LLT was not significantly different between male and female in each age group (P ＞ 0.05).LLT was positively correlated with age (r =0.334,P ＜ 0.001) and was not correlated with sex (r =0.107,P =0.226).LLT was positively correlated with upper eyelid ML score (r =0.295,P =0.001) and lower eyelid ML score (r =0.233,P =0.008).There was no significant correlation of LLT with BUT,FL or Schirmer Ⅰ test (all P ＞0.05).In the MGD group,there were positive correlations of LLT with upper eyelid ML score and lower eyelid ML score (all r =0.306,P =0.014),and no correlation of LLT with other examinations (all P ＞ 0.05).In the non-MGD group,there was no correlation of LLT with other examinations (all P ＞ 0.05).In a multivariate linear regression analysis,age and upper eyelid ML score were significantly related to LLT (β =0.254,P =0.005 for age and β =0.207,P =0.022 for upper eyelid ML score) in all dry eye patients.Age was the only factor related to LLT (β =0.382,P =0.002) in the MGD group.Upper eyelid ML score and lower eyelid ML score were higher in the MGD group than the non-MGD subgroup (all P ＜ 0.001).Conclusion LLT is positively correlated with age and ML score in dry eye patients.The measurement of tear film LLT,as an auxiliary examination in the diagnosis of dry eye disease,should be analyzed with the influential factors including age.

Objective: To investigate influence of Wenxin particle on cardiac electrophysiology in rats complicated with depression after myocardial infarction (MI). Methods: A total of 50 SD rats were randomly and equally divided into normal group, MI group, depression group, MI complicated with depression group (model group) and Wenxin particle group (Wenxin particle were given to model rats by gavage, 2 g/d, 28d). Model（MI complicated with depression）rats were made by acute ligation of left coronary artery and supply chronic unpredictable mild stress in order. The influences of Wenxin particle on cardiac electrophysiological indexes, such as monophasic action potential (MAP90), left ventricular effective refractory period (ERP) and ventricular fibrillation threshold (VFT) were evaluated in Wenxin particle group. Results: (1) Compared with normal group, there were significant decrease in behavior scores (P<0.05) in model group, after four-week treatment with Wenxin particle, their behavior scores significantly increased (P<0.01); (2) Compared with normal group, there were significant increase in MAPD90 and ERP, and significant decrease in VFT in model group (P<0.05); compared with model group, there were significant decrease in MAPD90 [(89.33±7.12) ms vs. (72.29±8.37) ms] and ERP [(84.00±6.57) ms vs. (68.00±7.43) ms], and significant increase in VFT [(7±3.11)V vs. (29±5.60)V] in Wenxin particle group, P<0.05. Conclusion: Wenxin particle can improve cardiac electrical remodeling in rats complicated with depression after myocardial infarction, including decrease monophasic action potential duration and effective refractory period, and raise ventricular fibrillation threshold.

All patients were randomly divided into treatment group(n=46, treated with PEG-IFNα-2a and deoxynucleotide acid injection, 200 mg/d, intravenous drip﹚and control group (n=46, treated with PEG-IFNα-2a﹚.Then assessment of CHB serum markers and liver function after 48 weeks continuous treatment. Results There were significant differences between the two groups in the HBV-DNA negative rate (60.7% v s 39.2%﹚, the HBeAg se roconversion rate (34.8%vs 15.2%﹚, the HBsAg negative rate (28.3% vs 10.8%﹚, the ALT levels(51.6±12.4 vs 72.3± 15.3﹚U/L, the AST levels(51.8±12.8 vs 70.8±13.4﹚U/L, the TBiL levels(23.5±7.6 vs 33.4±6.8﹚μmol/L, the ALP lev-els(87.2±24.2 vs 158.4±28.7﹚U/L, the serum levels of total protein (76.2±9.2 vs 65.2±8.2﹚g/L, albumin (37.5±8.3 vs 32.3±7.9﹚g/L, and the A/G levels (1.8±0.3 vs 1.4±0.3﹚(P<0.05﹚. What’s more, during the course of treatment, the neutropenia rate(6.5%vs 26.1%﹚,thrombocytopenia incidence rate (4.3% vs 23.9%﹚also had significant difference be-tween the treatment group and control group (P<0.05﹚. Conclusion There is synergistic clinical efficacy of deoxynu-cleotide combined pegylated interferonα-2a, and less adverse events during treatment.
