Objective To study the effect of edaravone on serum IL-6、TNF-α and neurologic functional in acute cerebral hemorrhage,discuss the protective mechanism of Edaravone on cerebral hemorrhage.Methods 80 casesof cerebral hemorrhage in 72h were randomly divided into treatment group(40 cases)and control group(40 cases),and the control group was given routine treatment,and the treatment group was administered with edaravone,30mg/d,for 14 days on the based treatment of the control group.The serum IL-6 and TNF-αwere detcted by ELISA before therapy and after treatment for 14 days.Neurological function deficit scores were utilized for assessment before given treatment.On the 21 th day after treatment,the patients were assessed again,and the efficacy was recorded.Results After 14 days treatment.the mean scale of NIHSS,the serum levels of IL-6 and TNF-α in treatment group were more obviously decreased than that in control group(all P＜0.05).Conclusion Edaravone could obviously alleviate inflammatory reaction on acute cerebral hemorrhage,which could effectively remove the generous free radicals and reduce the brain edema after intracerebral hemorrhage.So it could protect the tissue of brain.

Objective To investigate the clinical characteristics and related factors of metabolic disorder in acute cerebrevascular disease (ACVD) and to provide clinical basis for intervention of ACVD.Methods The clinical data of 202 healthy individuals (control group) and 621 cases of ACVD (341patients with cerebral infarction and 280 patients with cerebral hemorrhage) was analysed retrospectively.Based on the level of blood pressure,blood glucose and blood fat, 621 cases of ACVD were divided into me tabolism syndrome( MS ) group (hypertension + hyperglycemia + hyperlipidemia),two kinds of risk fatorsgroup (hypertension + hyperglycemia or hypertension + hyperlipidemia or hyperglycemia + hyperlipidemia),one kind of risk factor group (hypertension or hyperglycemia or hyperlipidemia) and no risk fastor group.Results Of the patients with cerebral infarction and cerebral hemorrhage 320 eases(93.8%) and 259 cases (92.5%) had hypertention,163 cases (47.8%) and 101 cases (36.1%) had hyperglycemia, 115 cases (33.7%) and 141 cases (50.4%) had hyperlipidemia, respectively. The blood pressure in one kind of risk factor group, two kinds of risk factors group and MS group was significantly higher than those in control group and no risk factor group,the body mass index (BMI), fasting plasma glucose (FPG),total cholesterol(TG)and low density lipoprotein cholesterol (LDL-C) in two kinds of risk factors group were higher than those in control group and no risk factor group (P <0.05). The age,BMI,blood pressure,FPG,TC,TG,high density lipoprotein cholesterol(HDL-C) and LDL-C had obvious correlation with ACVD. Conclusion ACVD is often combined with various kinds of metabolic disorders risk factors, suggesting that an effective control of metabolic disorders is benefit to intervention of ACVD.

Objective To discuss the cognition of the nursing disputes in undergraduates and the college nursing students in internship in Changchun and to provide some basis for them to improve the nursing quality in clinic.Methods The investigation was carried out to survey the cognition of the nursing disputes in 266 undergraduates and the college nursing students in internship in Changchun,and the results underwent analysis.Results Most undergraduates and college nursing students held the opinion that at present the relationship between patients and nurses was on a tight rope.94 people accounting for 72.3％ in undergraduate students,89 people accounting for 65.4％ in the college nursing students.Relevant factors which caused nursing disputes were related with the different education backgrounds.Conclusions We should make clear the causes of nursing disputes,and put forward the corresponding proposals according to nursing students with different education degrees.

Objective To compare the difference between crystalloids and colloids under goal-directed fluid therapy (GDFT) in elective hepatectomy.Methods Seventy patients undergoing hepatectomy, 42 males and 28 females, aged 18-65 years, ASA physical status Ⅱ or Ⅲ, were included and randomly divided into three groups base on fluid treatment: conventional fluid therapy (group C, n=24), goal-directed fluid therapy filled with colloids (group G1, n=23) and goal-directed fluid therapy filled with crystalloids (group G2, n=23).Group C received conventional fluid therapy mainly based on MAP while group G1 and group G2 received goal-directed fluid therapy based on MAP, stroke volume variation (SVV) and cardiac index (CI), and the Flotrac/Vigileo system was used to obtain SVV and CI in group G1 and group G2.250 ml colloids were administered if SVV>13% in group G1 while 250 ml crystalloids were administered in group G2.If CI<2.5 L·min-1·m-2, dobutamine 2.0-10.0 μg·kg-1·min-1 was given until CI≥2.5 L·min-1·m-2.The ScvO2, Lac and Glu were tested at 5 min before anesthesia induction (T1), 5 min before hepatectomy (T2), 5 min after hepatectomy (T3) and the end of operation (T4).The duration of operation, fluid requirement, urinary output, bleeding volume, and the use of vasoactive agent were recorded.The exhaust time, ambulation time and postoperative hospital stay were recorded.Preoperative and postoperative liver and kidney function tests and postoperative complications were followed up.Results Compared with group C, the total volume was lower, flatus time, ambulation time and postoperative hospital stay were shorter, ScvO2 at T3 and T4 were higher, Lac at T2-T4 were lower, Glu at T3 and T4 were lower, ALT and AST on the third day and the fifth day after surgery were lower in group G1 (P<0.05).Compared with group G1, the amount of crystalloids was increased, the incidences of postoperative nausea and vomiting were significantly higher in group G2 (P<0.05).There was no significant difference in flatus time, ambulation time and postoperative hospital stay between group G1 and group G2.Conclusion GDFT in hepatectomy propably improves the microcirculation and tissue oxygenation, protects liver function, promotes gastrointestinal function recovery and shortens postoperative hospital stay.GDFT using colloids bolus contribute to a much lower incidence of postoperative nausea and vomiting.There is no significant difference in tissue perfusion and postoperative recovery between colloids and crystalloids.

This study is to investigate the apoptotic induction effect of the combination of diosgenin and TNF-related apoptosis-inducing ligand (TRAIL) on non-small-cell lung cancer cell line A549 by using the Chou-Talalay method, and observe the mechanism of the combination. The apoptotic effect of diosgenin or TRAIL alone and their combination on A549 and normal cell line 293T proliferation was measured by MTT assay. Chou-Talalay method was used to evaluate the combination effect. Apoptosis was examined by Hoechst 33342 staining and flow cytometry assay. Western blotting detects the expression of apoptosis-associated proteins. Diosgenin or TRAIL alone can inhibit proliferation ofA549 in a concentration-dependent manner. According to the Chou-Talalay method, when f(a) = 0.1, CI > 1, when f(a) > 0.1, CI < 1. Combined with TRAIL, the IC50 of diosgenin decreases from 21.864 to 14.810 micromol x L(-1) (P < 0.05) on A549 cells. But for 293T cells, IC50 of diosgenin does not change significantly. As with Hoechst 33342 staining and flow cytometry assay, the apoptosis ratios also increased in the combination group. At protein expression level, combination-treated group displays increased Caspase-8, Caspase-9, Bid, Caspase-3 activation and PARP cleavage, significantly decreased Bcl-2 and increased Bax expression, and MAPK pathways were activated. The combination of diosgenin and TRAIL has synergistic effect on A549 cells.

Objective: To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention. Methods: Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension. Results: The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P＜0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01]. Conclusions The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.
