Objective To investigate the sleep structure of Parkinson's disease (PD) patients with rapid eye movement sleep behavior disorder (RBD) and its correlations with cognitive function, depressive state and motor function. Methods A total of 120 PD patients were enrolled in this study, and divided into PD+RBD group (n=45) and PD group (n=75) based on the presence or absence of RBD. Sleep structure was recorded for both groups. The scores of the Montreal Cognitive Assessment (MoCA), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Unified Parkinson's Disease Rating Scale Part Ⅲ (UPDRS-Ⅲ) and Scales for Outcomes in Parkinson's Disease-Autonomic (SCOPA-AUT) were compared between the two groups. The correlations of MoCA, HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores with sleep structure in the PD+RBD group were analyzed. Results The PD+RBD group showed significantly higher percentage of non-rapideye movement (NREM) at stage 1, arousal index, periodic limb movements during sleep (PLMS) and apnea-hypopnea index (AHI) compared to the PD group, while the percentages of NREM at stage 3, rapid eye movement (REM) sleep, sleep efficiency and lowest oxygen saturation were significantly lower (P < 0.05). The PD+RBD group also had significantly higher HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores, and significantly lower MoCA scores compared to the PD group (P < 0.05). In the PD+RBD group, the percentages of NREM at stage 1, arousal index, PLMS and AHI were positively correlated with HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores, and negatively correlated with MoCA scores (P < 0.05). Conversely, the percentages of NREM at stage 3, REM sleep, sleep efficiency and lowest oxygen saturation were negatively correlated with HAMA, HAMD, UPDRS-Ⅲ and SCOPA-AUT scores, and positively correlated with MoCA scores (P < 0.05). Conclusion PD patients with RBD exhibit disrupted sleep structure, which is closely associated with cognitive function, depressive state, motor function, and autonomic nervous system function.

To analyze the mediating role of anxiety and depression in perceived social support and fatigue in ICU patients′ families, and to provide a theoretical evidence for alleviating their fatigue status. A total of 223 family members of ICU patients who received treatment at the Affiliated Hospital of Jiangnan University from October 2020 to April 2021 were selected as the study subjects. The general data questionnaire, perceived social support scale (PSSS), generalized anxiety disorder scale (GAD-7), patient health questionnaire (PHQ-9) and fatigue assessment instrument (FAI) were used to conduct a survey. Among 223 family members of ICU patients, 155(69.51%) had fatigue problems. There were statistically significant differences in total fatigue scores of ICU patients′ family members in terms of gender, age, education level, relationship with patients, residence, payment method and per capita monthly income ( P<0.05). Anxiety, depression and fatigue were negatively correlated with perceived social support ( r are -0.353, -0.276 and -0.416, respectively, all P<0.01). Depression and fatigue were positively correlated with anxiety ( r are 0.808 and 0.703, respectively, all P<0.01), and fatigue was also positively correlated with depression ( r= 0.665, P<0.01). Anxiety and depression had a partial mediating effect on perceived social support and fatigue, and the total indirect effect size was 52.64%. Comprehensive intervention on the level of social support, anxiety and depression is helpful to improve the fatigue status of ICU patients′ family members.

Acute respiratory tract infection is the most common infectious disease in children, which seriously threatens children′s health.Rapid and accurate etiological diagnosis is of great significance for the clinical treatment and control of these diseases.Pathogen nucleic acid test was applied and became the main method of respiratory tract infection diagnosis for its high sensitivity and specificity.To regulate the application of pathogen nucleic acid amplification test in respiratory tract infection in children, improve the diagnosis level, expert consensus on nucleic acid amplification test of respiratory pathogens in children was prepared to guide the application and promote pathogens diagnosis ability.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

AIM: To explore the promoting effect of 2-APB on skin wound healing in mice and its potential mechanism. METHODS: KM mice were divided into 5 groups: control group, DMSO group, low (50 mg/L), medium (100 mg/L) and high (200 mg/L) concentration 2-APB group. On the back of each mouse's skin use a circular punch about 1 cm on both sides of the midline of the spine to make a skin wound with a diameter of 10 mm and as deep as the fascia. The control group was only wrapped with gauze and no drugs were applied; the DMSO group was applied 1 g DMSO/Vaseline ointment per day; in the 2-APB group, apply 1 g of 2-APB/Vaseline ointment at a corresponding concentration every day. Pictures were taken the next day to observe the healing, and the material was taken on the 21st day, HE staining was used to observe the pathological morphology of the wound and western blot to detect TRPM7, TGF-β, collagen-I and IL-1β expression. RESULTS: Compared with the control group and the DMSO group, different concentrations of 2-APB could significantly promote skin wound healing in mice (P<0.01), but there was no significant difference in wound healing rate between the DMSO group and the control group group. The results of HE staining showed that, compared with the control group group and the DMSO group, 2-APB could increase the collagen content of the wound and the thickness of the dermis (P<0.01), but there was no significant difference between the DMSO group and the control group group. At the same time, 2-APB could also significantly increase the expression of TGF-β and Col-I on the wound, and inhibit the expression of TRPM7 and IL-1β. CONCLUSION: Different concentrations of 2-APB (50, 100 and 200 mg/L) can promote skin wound healing, and its mechanism may be related to the inhibition of TRPM7.

Objective:To study the early-onset epilepsy of intracerebral hemorrhage and build a prediction model to evaluate its prediction efficiency.Methods:A cross-sectional investigation was conducted to construct a specialized optimized prediction model. The prediction model was converted into a visual optimized scoring scale, so as to quantify the probability of secondary epilepsy after intracerebral hemorrhage. Based on the current prediction model of acute cerebral infraction and post-stroke seizure (AIS-PSS), the evaluation efficacy of optimized score for secondary epilepsy after hemorrhagic stroke was explored.Results:① After sample size calculation and sufficient inclusion and exclusion, 159 patients with cerebral hemorrhage were continuously selected as the model group of this cross-sectional study. A total of 29 patients with early-onset epilepsy and 130 patients without secondary epilepsy were enrolled. The time span was from January 2021 to August 2021. In addition, 77 patients with acute cerebral hemorrhage from August 2021 to February 2022 were selected as the verification group, among which 12 patients had early-onset epilepsy and 65 patients had not any secondary epilepsy. ② There were significant differences in demographic characteristics such as diabetes history, cerebral infarction history, smoking history, National Institutes of Health Stroke Scale (NIHSS) score, intracerebral hemorrhage hematoma volume, serum creatinine (SCr), neuron-specific enolase (NSE), S-100 protein and intracerebral hemorrhage site between the two model groups with different prognosis (all P < 0.05). ③ The above indexes were included in univariate and multivariate Poisson regression analysis, and the results showed that the duration of diabetes [relative risk ( RR) = 1.229, 95% confidence interval (95% CI) was 1.065-1.896, P = 0.036], smoking history ( RR = 1.419, 95% CI was 1.133-2.160, P = 0.030), history of cerebral infarction ( RR = 1.634, 95% CI was 1.128-2.548, P = 0.041), hematoma volume of cerebral hemorrhage ( RR = 1.222, 95% CI was 1.024-2.052, P = 0.041), NES content ( RR = 1.146, 95% CI was 1.041-1.704, P = 0.032), were independent influencing factors to constitute the prediction model. The prediction model was converted into a visual optimized scoring scale in the form of a line diagram to obtain the prediction probability corresponding to the corresponding score. ④ Receiver operator characteristic curve (ROC curve) was used to test the evaluation efficiency of optimized score and AIS-PSS score for early-onset cerebral hemorrhage epilepsy. Relevant data of patients in the verification group were extracted according to the information of two scores, and the final score of each patient in the verification group was obtained. The score and prognosis were put into the ROC curve to evaluate the predictive ability of different prediction models. The results showed that the cut-off value of the optimized score and the AIS-PSS score were 144 points and 7 points, respectively, and the area under the ROC curve (AUC) and the Yoden index of the optimized score were slightly lower than the AIS-PSS score. However, compared with AIS-PSS score, there was no significant difference in the evaluation efficiency of optimized score for early-onset epilepsy ( Z = 1.874, P > 0.05). Conclusion:This study constructed a specific early-onset epilepsy prediction model for patients with hemorrhagic stroke, and transformed it into an optimized score that is easy for clinical use, and its evaluation efficiency is reliable.

Age, BMI, 2 h PG and HbA1c were all risk factors for diabetes mellitus after transplantation while 2 h-CPI was a protective factor.Quartile stratification was analyzed by regression model.And trend test was significant( P<0.05). Conclusions:Age, BMI, 2 h PG, HbA1c and 2 h-CPI are correlated with diabetes mellitus after kidney transplantation.

Objective:To understand the epidemiological characteristics of an outbreak of Chikungunya fever (CHIK) in Ruili city at Sino-Myanmar border area in Yunnan province, China, 2019.Methods:The data of CHIK cases in Ruili city were collected. Serum samples were collected from acute phase of the patients for the detection of the viral nucleic acid with real-time reverse transcription PCR assay.Results:A total of 121 CHIK cases (laboratory-confirmed cases) were reported in Ruili city in 2019, in which 98 were indigenous cases (80.99%) including 2 pregnant women and 3 neonatal cases (twin boys and 1 girl) were observed with vertical mother-to-child transmission), and 23 were imported cases (19.01%) from Myanmar. CHIK mainly occurred in Urban area (Mengmao town) and port area (Jiegao development zone) of Ruili city. The epidemic of CHIK lasted from September to November. The epidemic peak was in October (74.38%). The majority of patients were aged from 20—59 years (77.69%), in addition to 3 cases of mother-to-child transmission, the youngest was 3 months and the oldest 72 year-old. The male to female ratio was 1∶1.28 (53∶68). Occupational distribution of CHIK cases was mainly for the commercial service personnel (33.06%), home workers and unemployed persons (21.49%) and retiree (11.57%).Conclusions:During the outbreak of CHIK in Ruili in 2019, both indigenous and imported cases were detected. The imported CHIK cases from Myanmar were the main sources for local transmission of CHIK in Ruili city. This is the first time that a local epidemic of CHIK has occurred in Yunnan Province. It is necessary to strengthen control of the cross-border spread of CHIK in this area.

Objective To investigate the current situations of the frailty and the perceived social support and explore the influence of social support on the frailty in elderly maintenance hemodialysis patients.Methods The 237 elderly patients with maintenance hemodialysis were investigated by the Fried frailty phenotype and the perceived social support scale in this cross-sectional study.Results The prevalence of frailty was 163 (68.8％)in 237 patients.The level of perceived social support was low.The frailty was negatively correlated with the social supportscore,family support,friends support,and other support(r =-0.326,-0.129,-0.301 and-0.230,respectively,all P ＜0.05).Multiple logistic regression analysis showed that friends support,dialysis vintage,Charlson comorbidity index(CCI)score and activities of daily living(ADL)score were the main influential factors for frailty in elderly maintenance hemodialysis patients.Conclusions Medical staff should evaluate the frailty in elderly patients with maintenance hemodialysis,and the frailty can be alleviated by improving the support of friends.
