Essential tremor(ET)is one of the most common movement disorders, with a prevalence of 4.6% in people over 65 years old.Action tremor of both upper limbs at 4-12 Hz action tremor in both upper limbs is the main clinical feature of ET patients.ET was previously considered to be a benign isolated symptomatic disease, but in recent years, researches have found that ET is a family of diseases with high clinical and genetic heterogeneities.In addition to tremor, it can also be accompanied by soft neurological signs and various non-motor symptoms, leading to different degrees of function impairment in patients.Early comprehensive evaluation and long-term follow-up of patients with ET are essential.The standardized scale is the most important tool for ET assessment.This article reviews various tremor assessment scales.

Essential tremor (ET) is a common movement disorder. It is characterized by a distinctive 4-12 Hz action tremor typically affecting bilateral upper limbs. Existing drugs for ET mainly include β-blockers, anticonvulsants, benzodiazepines, etc. However, the efficacy of existing drugs is limited. With the development of the medical research, some progress has been made in the treatment of ET. The review will explore the recent advances in the treatment of ET,such as new drugs, surgical treatment, repetitive transcranial magnetic stimulation, rehabilitation treatment, etc., in order to provide clinical application prospects.

Objective:To explore the peripheral blood levels changes of soluble glycosylation end product receptor (sRAGE), endotoxin and Toll-like receptor (TLR) in patients with severe acute pancreatitis (SAP) complicated with peritoneal cavity infection, and clarify the relationship between indexes and pathogenetic condition.Methods:The clinical data of 105 patients with SAP in Shanghai Pudong New Area People′s Hospital from January 2017 to December 2020 were retrospectively analyzed. Among them, 28 cases had peritoneal cavity infection (infection group), and 77 cases had peritoneal cavity infection symptoms but undiagnosed (non-infection group). The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) at admission was recorded. When patients had the suspected symptoms and signs of peritoneal cavity infection, the serum levels of sRAGE, endotoxin, TLR4 and TLR9 were detected by enzyme-linked immunosorbent assay. The correlation between serum levels of sRAGE, endotoxin, TLR-4, TLR-9 and APACHE Ⅱ was analyzed by Pearson analysis; the risk factors of peritoneal cavity infection in SAP patients were analyzed by multivariate Logistic regression; the receiver operating characteristic (ROC) curve was drawn, and the diagnostic efficacy of serum sRAGE, endotoxin, TLR-4 and TLR-9 in peritoneal cavity infection were evaluated in patients with SAP; the Kaplan-Meier survival curve was drawn, and the comparison used log-rank test.Results:The serum sRAGE, endotoxin, TLR-4 and TLR-9 in infection group were significantly higher than those in non-infection group: (822.16 ± 104.51) ng/L vs. (728.09 ± 96.47) ng/L, (62.59 ± 20.11) ng/L vs. (41.62 ± 13.64) ng/L, (45.17 ± 8.54) μg/L vs. (37.34 ± 6.22) μg/L, (26.35 ± 6.73) μg/L vs. (20.02 ± 5.49) μg/L, and there were statistical differences ( P<0.01). Pearson correlation analysis result showed that the serum sRAGE, endotoxin, TLR-4 and TLR-9 were positively correlated with APACHE Ⅱ in patients with SAP ( r = 0.632, 0.556, 0.521 and 0.631; P<0.05). Multivariate Logistic regression analysis result showed that the combined organ function damage, shock, hypoxemia and serum sRAGE, endotoxin, TLR-4 and TLR-9 were independent risk factors of peritoneal cavity infection in patients with SAP ( P<0.05). ROC curve analysis result showed that the area under the curve for the serum sRAGE, endotoxin, TLR-4 and TLR-9 combined diagnosis of peritoneal cavity infection in patients with SAP was the largest, which was 0.910 (95% CI 0.838 to 0.957, P<0.01), with a sensitivity of 82.14% and a specificity of 87.01%. According to the ROC curve cut-off value of serum sRAGE, endotoxin, TLR-4 and TLR-9 (764.58 ng/L, 58.01 ng/L, 40.24 μg/L and 22.61 μg/L), the 28 patients with SAP complicated with peritoneal cavity infection were divided into high levels patients (21, 14, 23 and 22 cases) and low levels patients (7, 14, 5 and 6 cases); Kaplan-Meier survival curve analysis result showed that the 28-day survival rates in patients with high levels of sRAGE, endotoxin, TLR-4 and TLR-9 were significantly lower than those in patients with low levels (61.90% vs. 71.43%, 50.00% vs. 78.57%, 60.87% vs. 80.00% and 59.09% vs. 83.33%), and there were statistical differences ( P<0.05). Conclusions:The serum sRAGE, endotoxin, TLR-4 and TLR-9 have a high combined diagnostic value in SAP complicated with peritoneal cavity infection, and they are all related to the severity of the disease and have a significant impact on survival.

OBJECTIVES: Idiopathic intracranial hypertension (IIH) is a syndrome that excludes secondary causes such as intracranial space-occupying lesion, hydrocephalus, cerebrovascular disease, and hypoxic ischemic encephalopathy. If not be treated promptly and effectively, IIH can cause severe, permanent vision disability and intractable, disabling headache. This study aims to explore the clinical and image features for IIH, to help clinicians to understand this disease, increase the diagnose rate, and improve the outcomes of patients. METHODS: We retrospectively analyzed 15 cases of IIH that were admitted to Xiangya Hospital, Central South University, during January 2015 to September 2020. The diagnosis of IIH was based on the updated modified Dandy criteria. We analyzed clinical data of patients and did statistical analysis, including age, gender, height, weight, medical history, physical examination, auxiliary examination, treatment and outcome. RESULTS: There were 10 females and 5 males. Female patients were 22 to 42 years old with median age of 39.5. Male patients were 27 to 52 years old with the median age of 44.0. The BMI was 24.14-34.17 (28.71±2.97) kg/m CONCLUSIONS IIH primarily affects women of childbearing age who are overweight. The major hazard of IIH is the severe and permanent visual loss. Typical image signs have high specificity in IIH diagnosis. Prompt diagnosis and effective treatment are significantly important to improve the outcomes of patients.

Monitoring neuronal activity in vivo is critical to understanding the physiological or pathological functions of the brain. Two-photon Ca imaging in vivo using a cranial window and specific neuronal labeling enables real-time, in situ, and long-term imaging of the living brain. Here, we constructed a recombinant rabies virus containing the Ca indicator GCaMP6s along with the fluorescent protein DsRed2 as a baseline reference to ensure GCaMP6s signal reliability. This functional tracer was applied to retrogradely label specific V1-thalamus circuits and detect spontaneous Ca activity in the dendrites of V1 corticothalamic neurons by in vivo two-photon Ca imaging. Notably, we were able to record single-spine spontaneous Ca activity in specific circuits. Distinct spontaneous Ca dynamics in dendrites of V1 corticothalamic neurons were found for different V1-thalamus circuits. Our method can be applied to monitor Ca dynamics in specific input circuits in vivo, and contribute to functional studies of defined neural circuits and the dissection of functional circuit connections.

Objective:To explore the predictive factors of renal replacement therapy (RRT) in extracorporeal membrane oxygenation (ECMO) patients.Methods:The clinical data of 68 ECMO patients treated at Emergence Department of Jiangsu Provincial Hospital from January 2015 to December 2018 were retrospectively analyzed. Vasoactive-inotropic score (VIS) was used to assess the usage of vasoactive-inotropic drugs on day 1, 2 and 3 of ECMO (24 h VIS, 48 h VIS, and 72 h VIS). According to received RRT or not, patients were divided into the RRT group and non-RRT group. Age, gender, weight, VIS, presence of cardiac arrest before ECMO, ECMO mode, and ECMO treatment time were compared. Logistic regression analysis was used to identify predictive factors for RRT in ECMO patients.Results:Of the enrolled patients, 73.5% of ECMO patients received RRT. The mean age, 24 h VIS, ECMO failure and mortality of the RRT group were significantly higher than those of the non-RRT group ( P <0.05). The use of RRT was 87.8% in elderly ECMO patients (> cutoff age of 38.5 years). According to the cutoff value of 24 h VIS (33.75), ECMO patients were divided into the high VIS group and low VIS group. The rates of RRT and mortality were both exceeded 90% in the high VIS group, which was significantly higher than that of the low VIS group ( P <0.05). Logistic regression analysis showed that age ( OR=1.223) and 24 h VIS ( OR=1.033) were predictive factors of RRT in ECMO patients ( P <0.05). Conclusions:Age and 24 h VIS show the predictive value for RRT in ECMO patients.

Objective? To investigate the breast feeding knowledge and self-efficacy among hospitalized multiparae and to explore the influencing factors of breast feeding self-efficacy. Methods? From January to August 2018, we selected hospitalized multiparae at Yuyao People＇s Hospital and Zhejiang Provincial People＇s Hospital as subjects by simple random sampling. All of the multiparae were investigated with the general information questionnaire, breast feeding knowledge questionnaire and breastfeeding self-efficacy scale. A total of 400 questionnaire were sent out and 372 valid questionnaire were collected with 93.0% for the valid recovery rate. Results? Among 372 hospitalized multiparae, the total score of breast feeding knowledge questionnaire was (5.53±1.02); the total score of breastfeeding self-efficacy was (80.36±16.72). Single factor analysis showed that there were statistical differences in the scores of breast feeding self-efficacy among hospitalized multiparae with different ages, education levels, working state, living styles, income levels, delivery modes, number of complications, training for breast feeding, mastery of breast feeding knowledge, breast feeding for the first time (P＜ 0.01). Correlation analysis showed that breast feeding knowledge had a statistically positive correlation with the self-efficacy among hospitalized multiparae (r=0.117, P=0.026). Multiple linear regression analysis proved that the main influencing factors of breast feeding self-efficacy among multiparae included working state, number of complications, training for breast feeding and breast feeding knowledge with a statistical difference. Conclusions? The breast feeding knowledge and self-efficacy of hospitalized multiparae are not good enough. Communities and hospitals need to work hard together to improve styles and strategies of breast feeding education so as to increase the rate of breast feeding.

Objective To investigate the expression of miRNA-31 in peripheral blood mononuclear cells (PBMCs) of rheumatoid arthritis (RA) patients,and the relationship between miRNA-31 and disease activity of RA.Methods After obtaining the informed consent,peripheral blood samples of 56 RA patients,12 systemic lupus erythematosus (SLE) patients,6 Sj(o)gren's syndrome (SS) patients and 30 healthy controls were collected from the Department of Rheumatology,Peking University Third Hospital.RNA was extracted from the PBMCs which were separated by Ficoll-Paque PLUS.The expression of miRNA-31 in the PBMCs of RA patients,SLE patients,SS patients and healthy controls was detected by real-time Polymerase Chain Reaction (PCR).Furthermore,according to the RA disease activity score (DAS28),RA patients were divided into high,moderate and low disease activity groups and remission group,and miRNA-31 expression was compared between different groups.Data were analyzed using t test or Mann-Whitney U test.Results The expression of miRNA-31 in PBMCs of RA patients was 7.25 times (P=0.003 8) higher when compared with that of the control group.To be specific,the expression of miRNA-31 was 10.63 times in PBMCs of high activity RA group (P=0.01) and 8.95 times in moderate activity RA group (P=0.000 3) when compared with that of the control group,and there was no significant difference between low activity,remission groups and control groups in terms of miRNA-31 expression.Furthermore,the expression of miRNA-31 in PBMCs of SLE patients was not significantly different from the control and miRNA-31 expression in PBMCs of SS patients was 1.64 times (P=0.02) higher than that of the RA patients,but the average level of miRNA-31 was much less than that of RA patients.The increased miRNA-31 may serve as a diagnostic marker for disease activity of RA.

Objective To investigate the expression level of oxidized low density lipoprotein (ox-LDL) and its scavenger receptor scavenger receptor that binds phosphatidylserine and oxidized lipoprotein (SRPSOX) in patients with rheumatoid arthritis (RA),and to explore the relationship between ox-LDL and disease activity.Methods The serum ox-LDL in RA patients and healthy control group were detected by enzymelinked immunosorbent assay (ELISA),as well as the fluidox-LDL in RA,osteoarthritis (OA) and inflammatory arthritis (IA).The expression of SR-PSOX in mixed cells of RA and IApatients was detected by western blot.The expression of serum ox-LDL between RA groupand the control group was analyzed by t-test and non-parametric test.The correlation of serum ox-LDL expression levels in RA patients with C-reactive protein (CRP),erythrocyte sedimentation rate (ESR) and other inflammatory factors and disease activitywas analyzed by Pearson linear regression.Results The expression of ox-LDL in the serum of RA patients was significantly higher than that of normal control group [(3 076±131) mU/ml,(2 334±84) mU/ml,t=4.242,P＜0.01].The expression of ox-LDL in synovial fluid of RA patients was significantly higher than that of the OA group [(4 963±354) mU/ml],(3 956±347) mU/ml,t=2.372,P＜0.05).The expression of SR-PSOX in synovial fluid mixed cells of RA patients was higher than that of the IA group [(4.92±0.18) vs (0.24±0.04),t=33.53,P＜0.01].The expression of ox-LDL in serum of RA patients was negatively correlated with ESR,CRP and overall disease activity DAS28 (r=-9.42,P=0.009;r=-0.35,P=0.029 7;r=0.42,P=0.008 4).The expression of ox-LDL in the serum of RA patients with moderate disease activity was significantly higher than those patients with high disease activity [(3 302±138) mU/ml vs (2 464±228) mU/ml,t=3.335,P＜0.01],however,those with low disease activity and disease remission had higher serum ox-LDL expression but without statistical significant differences.After treated with anti-rheumatic drugs (DMARDs),serum ox-LDL of RA patients had a trend of slight increasing butwithout sign-ificant difference.The ox-LDL/LDL-C or ox-LDL/HDL-C was negatively not correlated with disease activity score in 28 (DAS28),ESR,CRP.Conclusion In RA patients,the expression of ox-LDL in the serum and synovial fluid is high and the SR-PSOX expressionin synovial fluid is also high.The serum ox-LDL levels are negatively correlated with ESR,CRP and DAS28,which are related to disease activity of RA.These findings suggest that the ox-LDL and the receptor SR-PSOX may play a role in RA pathogenesis,but needs further study.
