Objective To explore the effects of curriculum provision of nursing risk management in standardized training of new nurses. Methods Totally 140 new recruits nurses from the year 2011 to 2014 were divided into control group and experimental group with 70 cases each. The control group received standardized training. In addition, the experimental group added the curriculum of nursing risk management from different levels in the basis of standardized training. Data were statistically analyzed according to the examination results, incidence of nursing safety events ( adverse events) and post admittance rate of new nurses, in order to evaluate the effects. Results The examination results after standardized training and post admittance rate of the experimental group were higher than those of the control group:(83.61 ±6.90) points vs. (80.13±10.58) points,95.7%(67/70) vs. 82.9% (58/70), and there were significant differences, t=-2.309,χ2=6.05, P<0.05. And the incidence of nursing safety events ( adverse events) of the experimental group was lower than that of the control group in standardized training: 1.4%(1/70) vs.11.4%(8/70 ),and there was significant difference, χ2=4.275, P<0.05. Conclusions The curriculum provision of nursing risk management can enforce the safety consciousness of new nurses , culture them self-conscious and standardized nursing behaviors, reduce the incidence of nursing safety events ( adverse events) and improve the work ability of new nurses.

Objective To investigate the main risk factors influencing the pre-hospital delay of patients with acute ischemic stroke (AIS) for preventing methods.Methods A retrieval was done across the epidemiologic studies on pre-hospital delay of AIS patients during 2004 to 2015 using the key words of ischemic stroke,prehospital delay,treatment delay.According to the inclusion and exclusion criteria,the literature was collected and the literature quality was assessed.The data were extracted for meta-analysis by RevMan software.Results Sixteen epidemiologic studies were included.Totally,there were 2,966 cases of prehospital delay and 2,468 cases of non-delay.The pooled OR values and 95％ CI by multivariate analysis were as follows:the degree of awareness of stroke was 0.5 (0.3,0.82),emergency medical service (EMS) was 0.49 (0.29,0.85),National Institute of Health Stroke scale (NHISS) score 0.58 (0.36,0.95),outpatient visit as first visit 4.28 (1.44,12.74),distance 0.76 (0.61,0.95),medical history of ischemic stroke 0.37 (0.18,0.79) (with significant differences in OR value,P＜0.05).Conclusions The protective factors for pre-hospital delay of acute ischemic stroke patients include:strengthened awareness of stroke,effective EMS,high NHISS score,short distance,medical history of ischemic stroke.The main risk factor is that their outpatient visit is their first visit for medical treatment.Therefore,we need to enhance the health education to the patients and their families about awareness of stroke,improve the use of EMS and build complete and efficient green path for the stroke patient.

Objective To investigate the effect of Beraprost Sodium and atorvastatin in the treatment of TIA combined carotid plaques. Method 60 cases in our hospital with TIA and carotid artery plaques were randomly divided into observation group and control group, 30 cases in each group. The observation group was received beraprost natriuretic peptide and atorvastatin calcium therapy, the control group was treated with atorvastatin calcium. 12 months later,two groups were compared with carotid plaque area change and coagulation conditions. Results Carotid plaque area in observed group was significantly less than the control group (P<0.05). The differences of platelet agglutination test(PAgT), fibrinogen(Fg) , hypersensieive 3 C-reaction protein, total cholesterol(TC), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), TIA recurrence rate and incidence of ischemic stroke between two groups after treatment were statistically significant (P<0.05). Conclusion Beraprost Sodium and atorvastatin has a good effect in reducing carotid plaques area, adjusting blood fat and preventing TIA and ischemic stroke, It is worthy to clinical popularization and application.

Objective:To investigate the clinical efficacy and safety of gabapentin or topiramate combined with venlafaxine in the treatment of chronic migraine patients with generalized anxiety disorder.Methods:From June 2018 to February 2020, 127 patients with chronic migraine complicated with generalized anxiety disorder in the Second Affiliated Hospital of Guangxi Medical University were selected. The patients were divided into gabapentin combined with venlafaxine group (observation group, 64 cases) and topiramate combined with venlafaxine group (control group, 63 cases) according to the random number table method, and all patients were treated for 6 months. The headache attack days per month, headache visual analogue scale (VAS), migraine specific quality of life questionnaire V2.1 (MSQ V2.1), headache impact measurement-6 (HIT-6) score, Pittsburgh sleep quality index (PSQI) score were recorded before treatment and 3 and 6 months after treatment.Results:In observation group, 57 cases completed 3 months of treatment, and 53 cases completed 6 months of treatment. In the control group, 56 cases completed 3 months of treatment, and 50 cases completed 6 months of treatment. The headache attack days per month, headache VAS, HIT-6 and PSQI 3 and 6 months after treatment in 2 groups were significantly lower than those before treatment, observation group: (16.31 ± 5.02) and (15.69 ± 6.31) d vs. (22.62 ± 3.27) d, (3.67 ± 1.60) and (1.91±1.05) scores vs. (5.09 ± 1.43) scores, (49.34 ± 11.01) and (47.34 ± 9.05) scores vs. (60.25 ± 11.61) scores, (10.09 ± 2.81) and (9.68 ± 2.74) scores vs. (13.50 ± 2.81) scores; control group: (14.58 ± 7.37) and (9.92 ± 5.07) d vs. (23.05 ± 5.24) d, (4.74 ± 1.15) and (3.16 ± 1.60) scores vs. (5.90 ± 2.06) scores, (42.77 ± 8.02) and (40.09 ± 9.72) scores vs. (59.37 ± 9.08) scores, (9.66 ± 2.71) and (8.62 ± 2.07) scores vs. (14.61 ± 2.79) scores, and there were statistical differences ( P<0.05). The headache VAS 3 and 6 months after treatment in observation group was significantly lower than that in control group, and there was statistical difference ( P<0.05). The functional limitations, function loss, emotional function scores and total score of MSQ V2.1 3 and 6 months after treatment in 2 groups were significantly lower than those before treatment, observation group: (17.62 ± 9.81) and (16.01 ± 5.73) scores vs. (36.96 ± 9.55) scores, (12.17 ± 5.60) and (11.09 ± 3.27) scores vs. (17.06 ± 6.08) scores, (8.42 ± 2.17) and (8.94 ± 1.90) scores vs. (11.40 ± 4.09) scores, (33.24 ± 9.61) and (28.62 ± 5.04) scores vs. (62.75 ± 14.02) scores; control group: (17.08 ± 8.73) and (16.79 ± 5.19) scores vs. (36.82 ± 9.68) scores, (9.04 ± 4.48) and (8.90 ± 3.46) scores vs. (17.26 ±6.01) scores, (6.92 ± 2.61) and (5.15 ± 1.74) scores vs. (11.30 ± 5.47) scores, (31.65 ± 9.17) and (30.66 ± 6.04) scores vs. (62.91 ± 11.18) scores, and there were statistical differences ( P<0.05). There was no significant difference in the effective rate and the incidence of adverse drug reactions 3 and 6 months after treatment between 2 groups ( P>0.05). Conclusions:Gabapentin or topiramate combined with venlafaxine can reduce the degree of headache in chronic migraine patients with generalized anxiety disorder, reduce the number of headache days per month, improve sleep and improve the quality of life. However, the adverse reactions of gabapentin still need to be paid more attention.

Objective To compare the clinical effects between the two-level ladder ultrafiltration and sequential dialysis for hemodialysis patients with excessive water retention.Methods According to our hospital standard,23 patients with water retention during treatment with dialysis from January 2010 to September 2011 were selected.And they conducted a total of 198 dialysis.Both the two-level of high-level segment and sequential ultrafiltration step dialysis were set for 1 hour.Ultrafiltration accounted for one-third of the total,and the remaining two-thirds of the amount of ultrafiltration was completed in the remaining time.The blood pressure,ultrafiltration volume completed,plasma osmotic pressure,detection of vascular access pressure,and other observed indicators during dialysis were compared.Results The occurrence of hypotension and muscle spasms in two-level ladder ultrafiltration was slightly more than that in sequential dialysis,ultrafiltration volume completed actually in two-level ladder ultrafiltration was a little less than sequential dialysis.However,the difference was not statistically significant ( P ＞ 0.05 ).It took more time during sequential dialysis simple ultrafiltration,occasionally dialysis fluid stopped flowing and dialyzer and the trail tube lack of incubation,and some patients could not adapt to it.Amount of heparin( [7.48 ± 1.73 ] mg/h vs[6.25 ± 1.36] mg/h,t =5.374,P ＜ 0.01 ),venous pressure ( [ 128.62 ± 10.53 ] mm Hg vs [ 96.35 ± 11.84 ] mm Hg,t =20.166,P ＜ 0.01 ),trausmembrane pressure( [ 236.84 ± 23.65 ] mm Hg vs [ 175.94 ± 24.72] mm Hg,t =17.516,P ＜ 0.01 ) were significantly higher than those in the high level of ultrafiltration period.Mean arterial pressure ( MAP ) ( [ 100.48 ± 5.78 ] mm Hg vs [ 102.54 ± 5.39 ] mm Hg,t =2.571,P ＜ 0.05 ) and plasma osmotic pressure ( [ 311.42 ± 7.36] mOsm/( kg · H2O ) vs [ 3 1 7.31 ± 6.89 ] mOsm/( kg · H2O ),t =5.774,P ＜ 0.01 ) in high level period were significantly lower than those in the singal ultrafiltration period,and the MAP difference was higher than that in the singal ultrafiltration period ( [ 11.46 ± 6.53 ] mm Hg vs [ 9.42 ± 5.46 ] mm Hg,t =2.385,P ＜ 0.05 ).There is less symptomatic hypotension and other adverse reactions.Conclusion Two dialysis ultrafiltration method can both be used for patients with excessive water retention,they can reduce the ultrafiltraion complications and achieve ultrafiltration targets.Two-level ladder ultrafiltration with dialysis and ultra.filtration unity is more likely to be adopted by the clinic.

Objective To investigate the expression and significance of calcyclin binding protein (CacyBP)in the brain of rat model of traumatic brain injury(TBI).Methods Sixty 60 male SD rats were divided randomly into normal control group (n=10) and TBI group (n=50).The TBI model was created by using lateral head rotation device and subdivided into 6 h,24 h,72 h,7 d and 14 d group (10 rats per group).The expression and distribution of CacyBP in the rat brain was investigated immunohistochemically.The presence of the brown stained particles was considered aspositiveand lack of the stained particles agnegative. Results CacyBP was mainly distributed in the hippocampus,dentate gyrus and cortical neuron cytoplasm.Compared with the high level expression of CacyBP in the normal control group,the expression of CacyBP was decreased to the lowest in the rat brain at 6 h post TBI (P<0.01),became stronger gradually at 24 hours and recovered to normal at day 14,with no statistical difference compared with normal control group (P>0.05). Conclusion The lowest level expression of CacyBP after TBI indicates that CacyBP may play an important role in development of brain injury under effect of difierent mechanisms.

Objective To investigate the effect of methylprednisolone on T helper 17 cell (Th17 cells) related cytokines (interleukin (IL)-23,17A,21,22,6,and tansforming growth factor (TGF)-β) in serum and cerebrospinal fluid from patients with relapsing remitting multiple sclerosis and their effects on the pathogenesis.Methods We recruited relapsing remitting multiple sclerosis group (38 patients)and noninflammatory neurological disease group (20 controls),and detected the levels of IL-23,IL-17A,IL-21,IL-22,TGF-β and IL-6 in serum and cerebrospinal fluid (CSF) with ELISA kit in both controls and patients before and after treatment by methylprednisolone.Results After treatment in relapsing remitting multiple sclerosis patients,IL-17A,IL-23,IL-21,and IL-22 levels in cerebrospinal fluid and serum were significantly decreased,however,they were still higher than that in the non-inflammatory neurological disease patients.TGF-β levels was significantly increased (serum:(17.2 ± 5.9) pg/ml vs (34.1 ± 6.5) pg/ml,t =14.351,P =0.000 ; CSF:(26.4 ± 4.7) pg/ml vs (73.2 ± 19.7) pg/ml,t =16.352,P =0.000).The levels of TGF-β in serum and CSF in patients before treatment were lower than those of in non-inflammatory neurological disease patients (serum:(30.2 ± 8.9) pg/ml,t =6.769,P =0.012 ; CSF:(3 1.4 ± 7.5) pg/ml,t =9.368,P =0.017).However,the levels of TGF-β in CSF in patients after treatment were significantly higher than those in non-inflammatory neurological disease patients (t =9.138,P =0.000).Correlation analysis showed that IL-23 and IL-17A were positive correlation in the serum of relapsing remitting multiple sclerosis patients before treatment.Moreover,positive correlations among IL-23,IL-17A and IL-21 were detected in the CSF of relapsing remitting multiple sclerosis patients before treatment.Conclusions Decreased levels of IL-23,IL-17A,IL-21 and IL-22,and elevated levels of TGF-β were detected in serum and CSF of patients with relapsing remitting multiple sclerosis after methylprednisolone treatment.IL-23,IL-17A,IL-21,IL-22 and TGF-β might involve in the pathogenesis of relapsing remitting multiple sclerosis.

The expensive production of bioethanol is because it has not yet reached the 'THREE-HIGH' (High-titer, high-conversion and high-productivity) technical levels of starchy ethanol production. To cope with it, it is necessary to implement a high-gravity mash bioethanol production (HMBP), in which sugar hydrolysates are thick and fermentation-inhibitive compounds are negligible. In this work, HMBP from an atmospheric glycerol autocatalytic organosolv pretreated wheat straw was carried out with different fermentation strategies. Under an optimized condition (15% substrate concentration, 10 g/L (NH4)2SO4, 30 FPU/g dry matter, 10% (V/V) inoculum ratio), HMBP was at 31.2 g/L with a shaking simultaneous saccharification and fermentation (SSF) at 37 degrees C for 72 h, and achieved with a conversion of 73% and a productivity of 0.43 g/(L x h). Further by a semi-SFF with pre-hydrolysis time of 24 h, HMBP reached 33.7 g/L, the conversion and productivity of which was 79% and 0.47 g/(L x h), respectively. During the SSF and semi-SSF, more than 90% of the cellulose in both substrates were hydrolyzed into fermentable sugars. Finally, a fed-batch semi-SFF was developed with an initial substrate concentration of 15%, in which dried substrate (= the weight of the initial substrate) was divided into three portions and added into the conical flask once each 8 h during the first 24 h. HMBP achieved at 51.2 g/L for 72 h with a high productivity of 0.71 g/(L x h) while a low cellulose conversion of 62%. Interestingly, the fermentation inhibitive compound was mainly acetic acid, less than 3.0 g/L, and there were no other inhibitors detected, commonly furfural and hydroxymethyl furfural existing in the slurry. The data indicate that the lignocellulosic substrate subjected to the atmospheric glycerol autocatalytic organosolv pretreatment is very applicable for HMBP. The fed-batch semi-SFF is effective and desirable to realize an HMBP.
