Objective To compare the clinical effects of different doses of methylprednisolone therapy for children with severe hand,foot and mouth disease (HFMD).Methods According to different dosage methods, 240 children with severe HFMD were divided into large dose group,medium dose group and small dose group,80 cases in each group.The three groups were given different doses of methylprednisolone infusion on the basis of conventional treatment:large dose group(5 ~10mg·kg· -1 d -1 ),medium dose group(3 ~5 mg·kg· -1 d -1 ),small dose group (1 ~2mg · kg · -1 d -1 ).Results The time of fever sustaining,panic ease,mechanical ventilation,duration of hypertension and heart rate recovery of the medium -dose group were (47.93 ±4.72)h,(45.54 ±2.42)h,(51.43 ± 6.85)h,(53.66 ±7.62)h,(52.45 ±7.84)h,which were significantly shorter than those of the small -dose and large -dose group(all P <0.05).The incidence of turning to critically ill and the rate of ventilator use of the medium-dose group were significantly lower than those of the small -dose and large -dose group (all P <0.05 ).The incidence of pulmonary edema and pulmonary hemorrhage of the medium -dose group were significantly lower than those of the small -dose and large -dose group(all P <0.05).The differences among three groups were not statistically significant in the complications such as hypokalemia,hypocalcemia and gastrointestinal bleeding (all P >0.05 ). Conclusion Medium dose of methylprednisolone in the treatment of children with severe HFMD has significant effect and less adverse reactions,which is worthy of promotion.

Objective To investigate the effect of modified early warning scores (MEWS)on nosocomial emergency transshipment in primary hospital.Methods From July 2013 to February 2014,192 patients were selected as control group,and from March 2014 to October 2014,192 patients were selected as observation group.The control group conducted assessment and transshipment by experience.The observation group adopted MEWS to evaluate dis-ease and applied targeted treatment.Then,we compared the incidence of unsafe events,accuracy of handover,family member and the related departments 'satisfaction.Results After the implementation of MEWS,the incidence of unsafe events was decreased from 13.0% to 5.2%(χ2 =5.121 ).The accuracy of handover was increased from 85.4% to 94.3% (χ2 =8.248).The family member and related departments 'satisfaction were improved from 89.1%,87.5% to 97.4% and 96.4%,respectively (χ2 =15.561,χ2 =10.141).The differences were statistically significant (P <0.05).Conclusion MEWS can evaluate and classify the safety of patients objectively and effective-ly during nosocomial emergency transshipment.MWES can effectively reduce the incidence of unsafe events,increase the accuracy of handover,improve family member and related departments'satisfaction.

Objective To investigate the efficacy of proton pump inhibitors (PPI) combined with flupethixol melitracen in the treatment of non-erosive gastroesophageal reflux disease (NERD) with anxiety and depression.Methods Fifty six NERD patients with anxiety and depression were evenly divided into the positive treatment group and positive control group.Thirty NERD patients without anxiety and depression were set as negative control group.Both flupethixol melitracen (20 mg per day after breakfast) and PPI esomeprazole magnesium (20 mg per day,20 minutes before breakfast) were administrated in positive treatment group.Only esomeprazole magnesium was given in positive control group and negative control group and the dosage was same as that of positive treatment group.The treatment course of three groups was eight weeks.Before and after the treatment,the symptoms of patients were scored according to gastroesophageal reflux disease questionnaire (GERDQ),Hamilton anxiety scale (HAMA),Hamilton depression scale (HAMD) and Pittsburgh sleep quality index (PSQI).Adverse effects were also observed.Variance analysis was performed for the comparison among three groups.Variance analysis or Post-hoc analysis were used for comparison between two groups.Results The differences of different score value before and after treatment of three groups were statistically significant in total score of GERD Q,score of type A,score of type C,score of HAMA,score of HAMD and PSQI (F=6.32,3.93,5.63,49.61,78.69 and 7.07,all P＜ 0.05).The differences of the score value before and after treatment of positive treatment group in total score of GERD Q,score of type A,score of type C,score of HAMA,score of HAMD and PSQI (4.24±2.05,3.16±1.46,1(0,3),9.32±3.21 and 8.88±2.92) were all higher than those of positive control group (2.38±2.22,1.68±1.33,0(0,2),3.72±2.95 and 3.84±1.97) and negative control group (2.32±2.18,2.48±1.34,0(0,1),2.36±1.25 and 2.36±0.79).And the differences were statistically significant (positive treatment group vs positive control group:Post-hoc analysis,P=0.002,0.022,0.003,0.002 and 0.002; positive treatment group vs negative control group:Post-hoc analysis,P=0.001,0.021,0.004,0.001 and 0.001).The difference of the score value before and after treatment of positive treatment group in PSQI (4 (2,6)) was higher than that of negative control group (2 (1,3),Post-hoc analysis,P=0.001).Two cases of positive treatment group had mild dizziness and the symptom relieved after three to four days.Conclusions For NERD patients with anxiety and depression,anti-depression drug flupenthixol melitracen can be used and the effect is superior to using PPI alone.

Objective To observe the effects of an enriched environment (EE) on cognitive functioning and the synaptic plasticity of mice modeling post-stroke cognitive impairment (PSCI) and explore the possible mechanisms involved.Methods Mice modeling PSCI and sham-operated mice were randomly divided into 3 groups:sham-operated mice in a standard environment (the Sham+SE group),PSCI mice in a standard environment (the PSCI+SE group) and PSCI mice in an enriched environment (the PSCI+EE group).The cognitive functioning of all of the mice was quantified using a Morris water maze and their hippocampal long-term potentiation (LTP) was recorded using an electrophysiological method.The level of synaptophysin was detected using Western blotting.Synaptic ultrastructure in the hippocampus was imaged using electron microscopy.Results Compared with the Sham +SE group,the PSCI+SE group showed significantly poorer water maze performance and failed induction of contralateral LTP.Their average level of synaptophysin was significantly lower,and significant adverse changes in the synaptic ultrastructure of the hippocampus were observed,including a decreased number of synapses.The average width of the synaptic cleft,postsynaptic density and the interface curvature of the synapses were all less desirable.All of the measurements of the PSCI+EE group improved significantly compared to those of the PSCI+SE group,but were still significantly poorer than those of the Sham+SE group.Conclusions An enhanced environment can improve the cognitive functioning of mice modelling PSCI.It may be that an EE can improve synaptic plasticity in the hippocampus contralateral to the stroke.

Objective To observe the change of histone acetylation homeostasis of the central cholinergic circuits in mice with post-stroke cognitive impairment (PSCI). Methods The male ICR mice were divided into sham group (n=60) and PSCI group (n=60). The middle cerebral artery occlusion (MCAO) model was established. The Morris water maze test was used to test the cognitive function, and the changes of function and the histone acetylation homeostasis of the central cholinergic circuits of unaffected side were detected by molec-ular biology methods. Results Compared with the sham group, the scores of Morris water maze test decreased in PSCI group (t>29.412, P<0.05); while the acetylcholine (Ach) level decreased (t>26.227, P<0.05), as well as the expression of choline acetyltransferase (ChAT) mRNA and protein (t>28.593, P<0.05), acetylated histone H3 (Ac-H3) (t>24.126, P<0.05), phosphorylated cAMP response element-binding protein (p-CREB) and CREB binding protein (CBP) (t>25.634, P<0.05), and the acetylated histone level of M promoter of ChAT (t>24.704, P<0.05). Conclusion Transient MCAO could cause PSCI. The function of the central cholinergic circuits was impaired, especially the his-tone acetylation homeostasis of the central cholinergic circuits, such as the acetylated histone level of ChAT promoter decreased. All of that might be related with the decline of p-CREB and CBP level in the corresponding brain regions induced by stroke.

Objective:To investigate the occurrence of carotid artery abnormalities in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients and the related risk factors affecting the occurrence of carotid artery abnormalities.Methods:A total of 169 regular follow-up outpatients with HIV/AIDS from April 2003 to December 2019 in Peking Union Medical College Hospital, whose carotid artery ultrasound examination were performed from July 2015 to December 2019 were included. The patients were divided into young (≤44 years old), middle-aged and elderly (≥45 years old) according to their ages, and the physical examination data of the included patients were collected.The statistical methods were logistic regression analysis and single sample t test. Results:Among the 169 HIV/AIDS patients, 40(23.7%) had abnormal carotid artery and 129(76.3%) had no abnormal carotid artery. Middle-aged and elderly people (odds ratio ( OR)=3.85, 95%confidence interval (95% CI) 1.54-9.65, P<0.01), hypertension ( OR=6.24, 95% CI 1.95-20.00, P<0.01), hyperlipidemia ( OR=2.44, 95% CI 1.00-5.93, P<0.05), and elevated human leucocyte antigen (HLA)-DR + CD8 + /CD8 + ( OR=1.03, 95% CI 1.01-1.06, P<0.05) were the risk factors for carotid artery abnormality. The common carotid artery inner medium film thickness (IMT) of patients in HIV/AIDS group Ⅰ (20 to 30 years old), group Ⅱ (31 to 40 years old), group Ⅲ (41 to 50 years old) were (0.061 0±0.001 2), (0.062 9±0.001 4) and (0.065 6±0.002 6) cm, respectively, which were thicker than the control groups ((0.051±0.003), (0.056±0.004) and (0.063±0.002) cm, respectively). The differences were all statistically significant ( t=5.119, 4.775 and 1.739, respectively, all P<0.05). The common carotid artery IMT of patients in HIV/AIDS group A (30 to 44 years old) and group B (45 to 59 years old) were (0.062 6±0.001 1) and (0.072 3±0.003 4) cm, respectively, which were thicker than the control groups ((0.052±0.011) and (0.064±0.015) cm, respectively), the differences were both statistically significant ( t=9.520 and 3.012, respectively, both P<0.01). Conclusion:Younger HIV-positive people have a higher probability of abnormal carotid arteries and may be at greater risk of cardiovascular disease than HIV-negative people of the same age, suggesting that HIV-positive people, especially young people, should be examined early with ultrasound of the neck arteries to detect abnormalities and intervene as soon as possible.

Objective To investigate ablation characteristics of PVC/VT originating from left ventricle anterior papillary muscles.Methods This study included 10 patients of PVC/VT originating from left ventricle anterior papillary muscles from January 2015 to June 2016 in Beijing Anzhen Hospital.Electrophysiological mapping and radiofrequency ablation were completed using three-dimensional anatomical mapping system combined with three-dimensional intracardiac ultrasound technology.ECG and abaltion target diagram characteristics as well as the special anatomy were explored.Results All the 10 patients were successfully ablated and followed up for 12 months.One patient had recurrence within 12 months and no complications were recorded.The target sites localized at the tip (n =1),middle portion(n =4)or the base (n =5) of the LV-APM.Among 7 patients,the target sites were located at the anterior septal papillary muscle and in 3 patients were located in the free papillary muscle.9 patients were successfully ablated via anterograde trans-septal catheterization after the failure of retrograde approach.Premature QRS wave time were 152.80 ± 11.72 ms and 6 patients presented sharp potential at the targets during PVC/VT.Conclusions PVC/VT originating from left ventricle anterior papillary muscles have similar ECG and diagram characteristics that is different from which originating from left anterior fascicle.It is recommended to get the target via transseptalpuncure approach.Ablation target could be clearly positioned by three-dimensional intracardiac ultrasound technology.
