Objective To probe into the effects of applying standardized nursing ward round in nursing management.Method The nursing ward round was regularly conducted to analyze and discuss the difficulties in intensive care.Results After formulating the nursing ward round,the qualification rate of the basic nursing,specific nursing,the nursing of critical paitents,nursing records and the patient's satisfaction were higher than those before the use of nursing ward round(P<0.05).Conclusion The standardized nursing ward round may strengthen the training of nurses' core ability and the initiative of studying,reduce medical disputes,and improve the satisfaction of patients together with the quality of nursing.

Objective: To compare trophic effects of soluble substances derived from Schwann cells (SC) of neonatal and Wallerian degenerating segments of rats on facial motoneuron (FMN) cultures. Methods: Serum-free conditioned media of Schwann cell cultures (SC-CM) from facial and sciatic nerves of neonatal and Wallerian degenerating segments in adult rats were individually collected and concentrated by ultra-filtration with molecular weight cut-off at 30 000 and 10 000. The growth activities of FMNs in vitro were determined by means of MTT assay under the condition of serum-free medium added with different components of concentrated SC-CMs (SC-CMCs). The absorbance values were then statistically analyzed. Results: Survival and growth rate of FMN cultures in four kinds of SC-CMCs were significantly higher than that in media both with serum and non-serum and the difference between SC-CMCs was not statistically significant (P>0.05). Neurotrophic molecules were predominantly protein or peptide components with relative molecular weight larger than 30 000 and their trophic activity was positively related to total protein concentration in SC-CMCs. Conclusion: There were soluble trophic molecules with relative molecular weight larger than 30 000 for survival and neurite growth of FMN cultures in media with SC-CMCs derived from facial and sciatic nerves of neonatal rats and with SC-CMCs derived from Wallerian degenerating facial and sciatic nerves of adult rats. It might be reasonable to choose SC from sciatic nerves of rats on account of the findings from SC cultures on facial motoneurons.

Hyperuricemia is a risk factor for various diseases, but knowledge on acute hyperuricemia is still not sufficient. The present study was aimed to investigate the effect of acute hyperuricemia on red blood cells from hemorheological point of view, and to provide the reference for clinical treatment. The rats were gavaged with 500 mg/kg hypoxanthine and intraperitoneally injected with 100 mg/kg oxonate to induce the model of acute hyperuricemia. The same volume of blood samples were drawn within time period of 0, 1, 2, 3 and 6 h, respectively, from the inner canthus of rats to measure the serum uric acid, hemorheological parameters and the malondialdehyde level. It was found that in each period of 1, 2 and 3 h, the rats had significantly higher levels of uric acid. The integrated deformation index and relax index were increased. The hemolysis rate was significantly reduced. The plasma malondialdehyde level was obviously decreased at the end of 2 h. The results suggested that short-term elevated uric acid could improve the hemorheological parameters and the lipid oxidative level in red blood cells.

Objective To investigate the association between liver pathological changes and clinical features in patients with chronic HBV infection and alanine aminotransferase (ALT) 1-2 × upper limits of normal (ULN).Methods A total of 80 patients with chronic HBV infection and ALT 1-2 × ULN who were hospitalized in The First Affiliated Hospital of Bengbu Medical College from July 2015 to December 2016 were enrolled.All patients underwent liver biopsy,and according to positive or negative HBeAg,these patients were divided into two groups,and the association of liver pathological changes with age,sex,and HBV DNA load was analyzed.The t-test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.Results The HBeAg-negative group had significantly higher age and serum ALT level than the HBeAg-positive group (t =12.35 and 7.18,both P ＜ 0.01).Compared with the HBeAg-positive group,the HBeAg-negative group had a significantly higher proportion of patients with liver inflammation ≥G2 (54.8％ vs76.3％,x2 =53.68,P＜0.01) or fibrosis degree ≥S2 (57.1％ vs 73.7％,x2 =46.67,P＜0.01).Immunohistochemical staining was performed for 35 patients to measure the expression of HBsAg and HBcAg in the liver,and there were no significant differences in the staining scores of HBsAg and HBcAg between the two groups (both P ＞ 0.05).Conclusion Among patients with chronic HBV infection and slightly elevated ALT,HBeAg-negative patients have significantly worse conditions of liver lesions than HBeAg-positive patients.Liver biopsy is recommended for older patients with a long course of disease,in order to provide guidance for antiviral therapy.

Objective To explore the clinical efficacy and safety of Oxaliplatin combined with transcatheter arterial chemoembolization in the treatment of elderly patients with primary hepatocellular carcinoma.Methods One-hundred and three elderly patients with primary hepatocellular carcinoma who were treated in First Affiliated Hospital of Bengbu Medical College from January 2013 to July 2017 were selected.Based on the treatment methods,all patients were divided into the observation group and the control group by random number table method.Patients in the observation group (n=51) were treated with transcatheter arterial chemoembolization combined with Oxaliplatin,and those in the control group (n =52) treated with traditional hepatic arterial chemoembolization.The clinical efficacy and adverse reactions were compared and analyzed between groups.Results In the observation group,the partial remission rate (70.6％ vs.50％,x2 =4.555,P=0.033) and the total effective rate (72.6％ vs.50％,x2 =5.511,P=0.019) were significantly higher than those in the control group.Additionally,there was no significant difference in the incidence of adverse reactions between the two groups (all P＞0.05).Conclusions Combined with transcatheter arterial chemoembolization,Oxaliplatin could safely and effectively improve the prognosis of elderly patients with primary hepatocellular carcinoma..

BACKGROUND:There is less report about mitigating sustained bone grinding injuries during craniotomy based on a model of traumatic brain injury established using the modified Feeney's free-fall method. OBJECTIVE:To modify a modified traumatic brain injury model by altering the opening of the skull window. METHODS:Thirty-six Sprague-Dawley rats were equally randomized into sham group,model group and modified model group.The modified procedure of opening the bone window was used in the modified model group.Six to eight small holes of 0.3-0.5 mm in diameter were punched at the edge of the impact area and the drill was immediately withdrawn without touching the cortex.In the modified model group,the skull window was opened by using the modified method,while the skull window in the model group was opened using the conventional method.The modified model group and model group were established using the Feeney's free-fall method.In the sham group,only the skull window was opened without impact.The modified neurological severity scoring was performed at 1 day after modeling.T2 weighted imaging was performed and T2 values were measured at 1 and 7 days after modeling.Hematoxylin-eosin staining of the brain section was made for histopathological observation at 7 days after modeling.The level of blood viscosity,interleukin-6,interleukin-1β,and tumor necrosis factor-α were determined at 7 days after modeling. RESULTS AND CONCLUSION:Compared with the sham group,the modified neurological severity scores in the model group and modified model group were significantly increased at 1 day after modeling(P＜0.000 1).Meanwhile,the modified neurological severity scores in the modified model group were lower than those in the model group(P＜0.000 1).Compared with the sham group,the T2 values were significantly increased in the model group and modified model group at 1 and 7 days after modeling(P＜0.05),while the T2 values in the modified model group were lower than those in the model group(P＜0.05).Compared with the sham group,the level of blood viscosity,interleukin-6,interleukin-1β and tumor necrosis factor-α were increased in the model group and modified model group at 7 days after modeling(P＜0.05),while the level of interleukin-6 in the modified model group was lower than that in the model group(P＜0.05).To conclude,establishing a modified traumatic brain injury model based on the Feeney's free-fall method provides better controls of injury factors during cranial opening.
