Objective:To investigate the expression and clinical significance of microRNA-124(miR-124)and microRNA-1976(miR-1976)in the serum of patients with Parkinson's disease(PD).Methods:A total of 58 patients with PD were selected from September 2020 to June 2022 and categorized as the PD group.The Unified Parkinson's Disease Rating Scale(UPDRS)score was used to divide the PD patients into two groups: those with a UPDRS score≤60(25 patients)and those with a UPDRS score >60(33 patients). The Hoehn-Yahr grading scale was used to grade the PD patients.Additionally, 30 healthy individuals who had undergone a physical examination during the same period were selected as the control group.After collecting the subjects' serum, we performed real-time fluorescent quantitative PCR(qRT-PCR)to detect the expressions of miR-124 and miR-1976 in the serum.Logistic regression analysis was employed to analyze the influencing factors, and the diagnostic significance of serum miR-124 and miR-1976 in PD patients was evaluated using the receiver operating characteristic(ROC)curve.To predict the target genes of miR-1976, we utilized several software including TargetScan and Mirtarbase.Results:Compared to the control group, the PD group showed a significant down-regulation of serum miR-124 expression[(1.49±0.36) vs.(1.02±0.32)]( t=8.85, P<0.001), while miR-1976 expression was sharply up-regulated[(0.98±0.30) vs.(1.33±0.37)]( t=6.92, P<0.001). The low expression of serum miR-124 and the overexpression of miR-1976 were identified as independent risk factors for PD( OR>1, P<0.05). The Hoehn-Yahr rating of PD patients with a UPDRS score above 60 was higher than that of patients with a UPDRS score below 60[(3.42 ± 0.73) vs.(2.16 ± 0.42)]( t=3.05, P<0.05). However, there was no significant difference in serum miR-124 and miR-1976 expression between groups with different UPDRS scores[miR-124: (1.09±0.26) vs.(0.98±0.38)( t=0.89, P>0.05); miR-1976: (1.42±0.43) vs.(1.23±0.68)( t=0.62, P>0.05)]. The ROC analysis results demonstrated that miR-124 and miR-1976 had area under the curve(AUC)values of 0.832 and 0.797, respectively, in diagnosing PD.The corresponding cutoff values were 1.205 and 1.196, respectively.The sensitivity for miR-124 was 74.1%, while for miR-1976 it was 51.8%.The specificity for miR-124 was 77.8%, and for miR-1976 it was 90.1%.When both miR-124 and miR-1976 were combined in the diagnosis of PD, the AUC was 0.912, with a sensitivity of 76.4% and a specificity of 93.2%.Furthermore, it was found that miR-1976 targeted the PINK1 gene, suggesting its potential as a target gene in PD. Conclusions:The expression of miR-124 was found to be decreased in PD patients, while the expression of miR-1976 was increased.Both miR-124 and miR-1976 showed some reference value in PD diagnosis, and their combined diagnostic value was higher.This suggests that further study on their significance is warranted.However, it should be noted that the expressions of miR-124 and miR-1976 were not found to be correlated with the UPDRS score of PD patients.

Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Objective:To explore the influencing factors and the impact of artificial liver treatment on the prognosis and survival of patients with acute-on-chronic liver failure (ACLF).Methods:Clinical data from 201 cases with ACLF from January 2016 to December 2019 was retrospectively analyzed. The survival rate was calculated by the Kaplan-Meier method, the log-rank test of univariate analysis, and the multivariate analysis of the stepwise Cox regression forward method.Results:The median survival time of patients was 6 months, and the survival rates at 6, 9, and 12 months were 51.2%, 38.3%, and 29.9%, respectively. In univariate analysis, age, presence or absence of hypertension and upper gastrointestinal bleeding, treatment method, model for end-stage liver disease (MELD) score, and cholinesterase were associated with prognosis ( P < 0.05). Multivariate regression analysis results showed that MELD score was the main factor affecting the 1-year prognosis of ACLF patients ( P = 0.002). Artificial liver treatment was beneficial for the 1-year prognosis of ACLF patients aged < 50 years or with a MELD score of ≥20 ( P < 0.05 ). The relative risk ratio (RR) of mortality was 2.55 times higher in patients with advanced age (≥50 years old) than that of younger patients ( P < 0.001). Regression analysis was performed using age as a stratification factor, and upper gastrointestinal bleeding was related to the prognosis of younger patients, while choline esterase was related to the prognosis of advanced age. Regression analysis after stratified MELD score showed that age and hypertension were related to the prognosis of patients with MELD score < 20, and treatment method and age were related to the prognosis of patients with MELD score≥20. Conclusion:Artificial liver treatment is beneficial for the 1-year prognosis of ACLF patients. Age, MELD score, hypertension, and upper gastrointestinal bleeding are independent risk factors affecting the prognosis of ACLF patients.

OBJECTIVE: To investigate the effectiveness of arthroscopic autologous iliac bone grafting with double-row elastic fixation in treatment of recurrent anterior shoulder dislocation combined with massive glenoid bone defects. METHODS: Between January 2018 and December 2021, 16 male patients with recurrent anterior shoulder dislocation combined with massive glenoid bone defects were treated with arthroscopic autogenous iliac bone grafting and double-row elastic fixation. The patients were 14-29 years old at the time of the first dislocation, with an average age of 18.4 years. The causes of the first dislocation included falling injury in 5 cases and sports injury in 11 cases. The shoulders dislocated 4-15 times, with an average of 8.3 times. The patients were 17-37 years old at the time of admission, with an average age of 25.1 years. There were 5 left shoulders and 11 right shoulders. The preoperative instability severity index (ISIS) score of the shoulder joint was 5.8±2.1, and the Beighton score was 4.3±2.6. The University of California Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score were used to evaluate shoulder function, and the degree of the glenoid bone defect repair was observed based on CT after operation. RESULTS: All incisions healed by first intention, and no complication such as incision infection or neurovascular injury occurred. The patients were followed up 12 months. At 12 months after operation, UCLA score, Constant score, ASES score, and Rowe score all significantly improved when compared with the scores before operation ( P<0.05). CT imaging showed the degree of glenoid bone defect was significantly smaller at immediate, 6 and 12 months after operation when compared with that before operation ( P<0.05), and the bone blocks healed with the scapula, and bone fusion had occurred at 12 months. CONCLUSION Arthroscopic autologous iliac bone grafting with double-row elastic fixation is a safe treatment for recurrent anterior shoulder dislocation combined with massive glenoid bone defects, with good short-term effectiveness.

Objective: To investigate the perception about illness and identify its influencing factors among patients with non-alcoholic fatty liver disease ( NAFLD ) , so as to provide insights into the management of NAFLD patients. Methods: NAFLD patients admitted to Hangzhou First People's Hospital Affiliated to Medical School of Zhejiang University from January to June, 2020, were selected as the study subjects, and subjects' demographic features were collected using questionnaires, including gender, age and education level. The perception about illness, coping models and social support were assessed using the Brief Illness Perception Questionnaire (BIPQ), Medical Coping Modes Questionnaire ( MCMQ ) and Social Support Rating Scale ( SSRS ), respectively, and factors affecting the perception about illness were identified using multivariable linear regression analysis among NAFLD patients. Results: The 286 respondents included 151 males ( 52.80% ) and 135 females ( 47.20% ), and had a mean age of ( 55.27±10.39 ) years. The mean illness perception score was 38.55±9.21 among the respondents. The mean SSRS score was 42.90±8.64. The mean coping mode scores of confronce, avoidance and resignation were 23.51±4.30, 17.49±2.82, and 7.12±2.05, respectively. Multivariable linear regression analysis identified education level ( high school, β'=-0.216; diploma and above, β'=-0.355 ), household monthly income per capita ( β'=-0.372 ), regular exercise ( β'=-0.310 ), coping modes ( confronce, β'=-0.326; avoidance, β'=-0.191 ) and social support level ( β'=-0.259 ) as factors affecting the perception about illness among NAFLD patients. Conclusion Negative perceptions about illness are found among NAFLD patients, and household income, education level, regular exercise and coping modes are factors affecting the illness perception among NAFLD patients.

Objective To analyze the clinical characteristics and prognostic factors of chronic hepatitis B (CHB) patients complicated with metabolic associated fatty liver disease (MAFLD). Methods A total of 114 CHB patients and 101 CHB patients complicated with MAFLD who underwent liver biopsy between 2005 and 2018 were included. A long-term cohort was established with the time of liver puncture as the baseline, and decompensated cirrhosis, liver cancer, liver transplantation and death related to liver disease as the clinical endpoints. The patient's NAS score, hepatitis inflammation activity (G) and fibrosis stage (S) were scored for the liver biopsy. According to fibrosis stage, patients were divided into no significant fibrosis (S0-1) and significant fibrosis (S2-4) groups. The clinical characteristics and prognosis of the CHB patients with or without MAFLD at the same fibrosis stage were compared. CHB patients with MAFLD were divided into NAS < 4 and NAS≥4 groups according to NAS score, and the influence of NAS score on clinical outcomes of patients was analyzed. The independent samples t -test / Wilcoxin test was performed for comparison of continuous data and the chi-square test was used for comparison of categorical data between groups. Survival analysis was performed using Kaplan-Meier survival cure and compared using log-rank test. Cox multivariate regression analysis was used to identify prognostic factors. Results The BMI, blood glucose and TC in CHB patients with MAFLD group were significantly higher than those in CHB alone in each fibrosis stage ( P < 0.05). In patients without significant fibrosis, the levels of ALT ( Z =-2.249, P =0.025), AST ( Z =-2.512, P =0.012) and GGT ( Z =-5.261, P < 0.001) in the complicated group were higher than those in the CHB group. With a median follow-up time of 8.0 years, the Kaplan-Meier survival analysis revealed that the complicated MAFLD significantly reduced the liver event-free survival rate of CHB patients ( χ 2 =7.607, P =0.006). Cox multivariable analysis revealed MAFLD ( HR =5.76, 95% CI : 1.54 - 21.48, P =0.009) was an independent risk factor for liver-related outcomes. In CHB patients with MAFLD, the ALT ( Z =-3.139, P =0.002), AST ( Z =-2.898, P =0.004), and GGT ( Z =-2.260, P =0.024) of patients with NAS≥4 were higher than those of patients with NAS < 4. We found that significant fibrosis ( HR =4.83, 95% CI : 1.23 - 18.91, P =0.024) was associated with the poor prognosis of CHB patients with MAFLD. Conclusions CHB patients with MAFLD are more likely to have impaired liver function in the early stage and the disease progresses more rapidly. Complicated MAFLD will increase the risk of liver-related events in patients with CHB, and significant fibrosis is an independent risk factor for adverse outcomes in CHB patients with MAFLD.

Objective:To analyze the correlation among social support, positive coping and job burnout among nurses in Department of Infectious Diseases.Methods:From March 2020 to June 2021, convenience sampling was used to select 110 nurses from Department of Infectious Diseases of 8 ClassⅢ hospitals in Hangzhou, Zhejiang Province as the research object. The General Information Questionnaire, Maslach Burnout Inventory, Social Support Rating Scale (SSRS) , and Simple Coping Style Questionnaire (SCSQ) were used to investigate the nurses. Pearson correlation analysis was used analyze the correlation among job burnout, social support and positive coping. A total of 110 questionnaires were distributed, and 102 effective questionnaires were recovered, with an effective recovery rate of 92.73%.Results:Among the 102 nurses in Department of Infectious Diseases, 17.65% (18/102) were in mild burnout, 57.84% (59/102) were in moderate burnout, and 20.59% (21/102) were in severe burnout. The SSRS total score and each dimension score of nurses in Department of Infectious Diseases were positively correlated with the positive coping subscale score of SCSQ ( P<0.05) , and negatively correlated with the emotional exhaustion subscale and depersonalization subscale score of the Maslach Burnout Inventory ( P<0.05) , but it was positively correlated with the personal achievement subscale score ( P<0.05) . Conclusions:The overall job burnout of nurses in Department of Infectious Diseases was moderate to severe level, and social support and positive coping were correlated with job burnout. Nursing managers should develop measures to reduce the job burnout of nurses in Department of Infectious Diseases.

Rare diseases have been a major challenge for clinical medicine and public health challenge in China. One of the effective measures is to conduct proactive research on rare diseases to deal with the disease burden of the diseases. However, low prevalence, disperse distribution of patients, lack of knowledge about the disease course, and phenotype heterogeneity hamper the development of research for rare diseases. Recently, it has been found that patients registry is effective in understanding the course of the disease and accu- mulating the cases and data of clinical research or clinical trial design. At present, most of developed countries or regions in the world have promoted clinical research and clinical trials of new medications on rare diseases by using the registration of rare disease. In 2016, Peking Union Medical College Hospital established China's first registry system at the national level-National Rare Disease Registry System of China(NRDRS). NRDRS has accumulated 68 137 cases data registered by the researchers from China's 101 collaborating hospitals in 29 provinces/municipalities/autonomous regions, covering 171 different, and forming 188 cohorts. To date, NRDRS complete the initial stage of resources buildup.Nex stage will be focused on clinical research and clinical trials related to rare diseases based on NRDRS. This article is on the process of building NRDRS, the potential support for conducting clinical research and clinical trials related to rare diseases, and the challenges will be faced.

Objective: The primary aim was to evaluate the influence of depressive and anxiety symptoms on the 1-year recurrence rate of non-muscle invasive bladder cancer (NMIBC) patients. The secondary aim was to examine the risk factors leading to psychological distress. Methods: A total of 104 NMIBC patients were enrolled for interviews, and the Hospital Anxiety and Depression Scale (HADS) questionnaire survey was administered 1 month after their operation. Their cystoscopy results were followed up. The risk factors affecting their 1-year recurrence rate were evaluated through univariate analysis, Cox regression and Kaplan-Meier analysis. The risk factors causing depressive and anxiety symptoms were evaluated through univariate analysis and logistic regression. Results: In addition to American Urological Association risk stratification, depressive symptoms were another independent risk factor for recurrence in NMIBC patients (HR: 2.493, 95% CI: 1.048–5.930, p=0.039), and the increase in the recurrence rate was highly significant in intermediate-risk patients (HR: 8.496, 95% CI: 2.178–33.138, p=0.019). Anxiety symptoms were not an independent risk factor for recurrence (HR: 1.655, 95% CI: 0.714–3.837, p=0.240). We also observed that the burden of medical expenses of NMIBC on the family was an independent risk factor for depressive symptoms (p=0.029) and anxiety symptoms (p=0.048); chronic pain was an independent risk factor for anxiety symptoms (OR: 3.447, 95% CI: 1.182–10.052, p=0.023). Conclusion Depression symptoms are an independent risk factor for recurrence in NMIBC patients. Moreover, the burden of medical expenses on the family is an independent risk factor for depressive and anxiety symptoms in NMIBC patients. Additionally, chronic pain is a risk factor for anxiety symptoms in NMIBC patients. This study provided a theoretical foundation for clinical oncologists to pay more attention to the mental health of NMIBC patients.
