Objective:To evaluate the clinical features of dystonia in patients with different types of atypical Parkinson syndrome (APS).Methods:A total of 104 patients with APS admitted in the Department of Neurology, Beijing Hospital from January 2015 to June 2023 were enrolled in the study, including 57 cases of multiple system atrophy (MSA), 38 cases of progressive supranuclear palsy (PSP) and 9 cases of corticobasal degeneration (CBD). Among 104 cases there were 63 males (60.6%), the mean age of patients was (62.3±8.9) years (54 to 73 years). The sex, age at onset, disease duration, first symptom, clinical features of dystonia and other neurological signs, response to levodopa therapy, numbers of Hoehn & Yahr scale≥3 after 3 years of disease, and MRI findings were documented in patients with different type APS.Results:The overall frequency of dystonia in this series was 45.2%(47/104), and 33.3% (19/57) for MSA group, 50.0% (19/38) for PSP group, 9/9 for CBD group. The types of dystonia were anterocollis, retrocollis, blepharospasm, oromandibular, foot/limb dystonia, Pisa syndrome and myoclonus. In all 47 cases presenting dydtonia, dystonia was not the first complaint and it did not respond to levodopa therapy.Conclusion:In this series of atypical Parkinson syndrome, dystonia is a common feature of the disease, while it is not the first symptom at disease onset, and usually does not respond to levodopa therapy.

Objective:To conduct a nationwide physician survey to better understand clinicians’ disease awareness, treatment patterns, and experience of Waldenstr?m macroglobulinemia (WM) in China.Methods:This cross-sectional study was conducted from February 2022 to July 2022 by recruiting clinicians with WM treatment experience from hematology, hematology-oncology, and oncology departments throughout China. Quantitative surveys were designed based on the qualitative interviews.Results:The study included 415 clinicians from 219 hospitals spread across thirty-three cities and twenty-two provinces. As for diagnosis, the laboratory tests prescribed by physicians for suspected WM patients were relatively consistent (92% -99% recommendation for laboratory, 79% -95% recommendation for pathology, 96% recommendation for gene testing, and 63% -83% recommendation for imaging examination). However, from a physician's perspective, there was 22% misdiagnosis occurred in clinical practice. The rate of misdiagnosis was higher in lower-level hospitals than in tertiary grade A hospitals (29% vs 21%, P<0.001). The main reasons for misdiagnosis were that WM was easily confused with other diseases, and physicians lacked the necessary knowledge to make an accurate diagnosis. In terms of gene testing in clinical practice, 96% of participating physicians believed that WM patients would require gene testing for MYD88 and CXCR4 mutations because the results of gene testing would aid in confirming diagnosis and treatment options. In terms of treatment, 55% of physicians thought that the most important goal was to achieve remission, while 54% and 51% of physicians wanted to improve laboratory and/or examination results and extend overall survival time, respectively. Among patients with treatment indications, physicians estimated that approximately 21% of them refused to receive treatment, mainly owing to a lack of affordable care and disease awareness. When selecting the most appropriate treatment regimens, physicians would consider patient affordability (63% ), comorbidity (61% ), and risk level (54% ). Regimens containing Bruton tyrosine kinase inhibitor (BTKi) were most widely recommended for both treatment-na?ve and relapsed/refractory patients (94% for all patients, 95% for treatment-na?ve patients, and 75% for relapsed/refractory patients), and most physicians recommended Ibrutinib (84% ). For those patients who received treatment, physicians reported that approximately 23% of patients did not comply with the treatment regimen due to a lack of affordability and disease awareness. Furthermore, 66% of physicians believe that in the future, increasing disease awareness and improving diagnosis rates is critical. Conclusions:This study is the first national physician survey of WM conducted in China. It systematically describes the issues that exist in WM diagnosis and treatment in China, such as a high rate of misdiagnosis, limited access to gene testing and new drugs, and poor patient adherence to treatment. Chinese doctors believe that improving doctors’ and patients’ understanding of WM is one of the most urgent issues that must be addressed right now.

Objective To analyze the distribution characteristics of traditional Chinese medicine(TCM)syndrome types in patients with osteoporosis and the distribution differences of clinical and serological indicators in TCM syndrome types.Meth-ods A total of 69 patients with osteoporosis were collected from the Third Affiliated Hospital of Guangzhou University of Chinese Medicine and Qifu Hospital Affiliated to Jinan University.The general information,bone mineral density T value,fasting periph-eral venous blood in the morning were collected.The expression of telomerase protective factor 1(POT1),telomerase reverse transcriptase(TERT),serum 8-hydroxy-2'-deoxyguanosine(8-OHdG)and superoxide dismutase 2(SOD2)were detected by ELISA.Finally,the above data were statistically analyzed.Results There were significant differences in body weight,height,bone mineral density,POT1,TERT,and 8-OHdG among the four syndromes(P＜0.05).In terms of correlation,the relation-ship between bone mineral density and each parameter in different syndrome types was explored.The bone mineral density of qi stagnation and blood stasis syndrome was positively correlated with SOD2 value.There is a positive correlation between bone min-eral density and 8-OHdG in patients with Yin deficiency of liver and kidney.TERT was positively correlated with qi stagnation and blood stasis syndrome.Liver and kidney Yin deficiency syndrome was positively correlated with weight and bone mineral den-sity,and negatively correlated with TERT value.Weight was negatively correlated with qi and blood stasis syndrome.Conclusion In TCM syndrome differentiation of osteoporosis,there were statistical differences in weight,height,bone mineral density,ser-um POT1,TERT and 8-OHdG among Qi-stagnation and blood stasis,spleen-kidney Yang deficiency,liver-kidney Yin deficiency and Qi-blood-peace syndrome.In different syndrome types,serum SOD2 and 8-OHdG were the influencing factors of bone miner-al density.Serum TERT and 8-OHdG are the main factors affecting the dialectical classification of osteoporosis.

This paper summarized the experience of Professor FANG Dingya in staged treatment of Sjögren's syndrome from the perspective of dryness toxin. It is believed that the cause of Sjögren's syndrome is externally-contracted dryness， consumption of essence and fluid， congenital and acquired essence deficiency， depleted essence and insufficient blood， and the core mechanism is internal accumulation of dryness toxin. The treatment can be divided into three stages， that is dryness toxin transforming into fire-heat， damp-heat and phlegm-stasis， from the perspective of dryness metal qi transformation. It is emphasized to dispel pathogen mainly， to clear and moisten with yin-nourishing medicinals in supplementation， and to treat by stages based on syndrome differentiation. For dryness toxin with fire-heat， it is suggested to moisten dryness， resolve toxins and subdue fire， with self-made Runzao Jiedu Decoction （润燥解毒汤） in modification. For dryness toxin with damp-heat， the method of nourishing yin， clearing heat and draining dampness should be used， and Chunze Decoction （春泽汤） in modification is suggested. For dryness toxin with phlegm-stasis， it is recommended to unblock collaterals， disperse phlegm and dissipate stasis， with self-made Sanyu Xiaotan Decoction （散瘀消痰汤） in modification.

Abstract: Objective To investigate the clinical features and risk factors for severe tsutsugamushi disease, so as to provide reference for diagnosis and differentiation of severe tsutsugamushi disease as soon as possible. Methods The clinical data of 178 cases of inpatients with tsutsugamushi disease admitted to the Guangzhou Eighth People's Hospital, Guangzhou Medical University from January 2016 to September 2021 were collected and analyzed according to their gender, age, underlying diseases, clinical characteristics at admission, laboratory examination results within 24 hours of admission and epidemiological history. The patients were divided into the severe group and the non-severe group according to the diagnostic criteria. The data of clinical characteristics, laboratory examination and prognosis of the two groups were compared. Multivariate logistic regression analysis was performed on the variables with statistical significance and the receiver operating characteristic curve (ROC) was drawn. Results A total of 178 patients were included in this study, with 37 in the severe group and 141 in the non-severe group. Compared with the non-severe group, the age of the severe group was older, the underlying diseases were more, the incidence of dyspnea and the levels of white blood cell, total bilirubin, aspartate aminotransferase, lactate dehydrogenase, cystatin C, uric acid and serum creatinine were significantly increased, the levels of platelet and albumin were significantly decreased (all P<0.05). The dyspnea [odds ratio (OR value)=8.93, 95% confidence interval (CI): 1.200-66.424; P=0.032], total bilirubin (OR=1.091, 95%CI: 1.028-1.159; P=0.004) and serum creatinine (OR=1.052, 95%CI: 1.004-1.102; P=0.033) were independent risk factors for severe tsutsugamushi disease. The area under ROC curve of total bilirubin and serum creatinine were 0.777 and 0.764, respectively (both P<0.01), indicating high predictive value for severe tsutsugamushi disease. The optimal cut-off value for total bilirubin was 23.01 µmol/L, with a sensitivity of 54.10% and a specificity of 90.60%; the optimal cut-off value for creatinine was 126.45 µmol/L, with a sensitivity of 43.20% and a specificity of 100.00%. The case fatality rate of severe tsutsugamushi disease was 2.70%. Conclusions The patients with severe tsutsugamushi disease are older, and have more underlying diseases. Dyspnea, increased total bilirubin and elevated serum creatinine are independent risk factors for severe tsutsugamushi disease, which can help in the early identification of severe tsutsugamushi disease early.

Objective:To analyze the epidemiological and clinical characteristics of patients with tsutsugamushi disease in Guangdong Province from 2016 to 2021, and to provide a reference for clinical diagnosis, treatment, scientific prevention and control of tsutsugamushi disease.Methods:A retrospective analysis was conducted to collect the information of patients with tsutsugamushi disease admitted to Guangzhou Eighth Hospital Affiliated to Guangzhou Medical University from 2016 to 2021, including the basic information, epidemiological characteristics, clinical manifestations, auxiliary examinations, complications, misdiagnosis at first diagnosis and treatment outcomes.Results:Among 155 patients with tsutsugamushi disease, there were 75 males (48.39%) and 80 females (51.61%), with an e age of (54.41 ± 13.78) years old, and 30 cases (19.35%) had other underlying diseases. The peak time of onset was from June to September. There were 97 local patients (62.58%) in Guangzhou, and 58 cases (37.42%) in other prefecture-level cities; 76.77% (119/155) had a history of field activities before the onset of the disease. 36.13% (56/155) were farmers. The most common clinical manifestations were fever (100.00%, 155/155), chills and/or shivering (77.42%, 120/155), headache and/or dizziness (74.19%, 115/155), fatigue (65.81%, 102/155), eschar or ulcer (92.90%, 144/155), and lymphadenopathy (49.68%, 77/155). The laboratory test results mainly showed a decrease in eosinophils (81.94%, 127/155), a decrease in hematocrit (78.71%, 122/155), a decrease in hemoglobin (52.26%, 81/155), a decrease in platelet count (50.97%, 79/155), a decrease in albumin (92.26%, 143/155), an increase in lactate dehydrogenase (90.32%, 140/155), an increase in adenosine deaminase (88.39%, 137/155), and an increase in alanine aminotransferase (85.16%, 132/155), elevated aspartate aminotransferase (85.16%, 132/155), and elevated procalcitonin (52.90%, 82/155); 30 cases (19.35%) were positive for the Weil-Felix Test. There were 95 cases (61.29%) with abnormal chest imaging results, and 34 cases (21.94%) with abnormal abdominal ultrasound or CT results. Common complications were toxic hepatitis, pulmonary infection, organ failure, and acute kidney injury, etc. The misdiagnosis rate of the initial diagnosis of this disease was 75.48% (117/155). Doxycycline and symptomatic and supportive therapy were given, 154 patients (99.35%) were cured or improved and discharged from hospital.Conclusions:Tsutsugamushi disease is prevalent in summer and autumn in Guangdong Province. Before the onset, most of the patients have a history of field activities. Farmers are susceptible people. Its clinical manifestations are diverse, and can affect multiple systems and organs. There are many complications, and doxycycline can be used for anti-infection treatment, with a high cure rate.

Objective:To investigate the incidence of various non-motor symptoms (NMS) in early stage of Parkinson′s disease (PD) patients and the differences between the body-first and brain-first subtypes.Methods:A total of 121 patients with PD (Hoehn-Yahr stage 1-2) were recruited from PD Clinic, Department of Neurology, Beijing Hospital from January 2012 to January 2015. The general information and clinical features of the patients were collected. The minimal diagnostic criteria of parasomnias described in the International Classification of Sleep Disorders-Revised were used to diagnose rapid eye movement sleep behavior disorder (RBD).According to the sequence of RBD and motor symptoms, the patients were divided into 2 groups: body-first subtype and brain-first subtype. NMS was evaluated by the Non-Motor Symptom Questionnaire (NMSQuest). The clinical features and the incidence of various NMS were compared between the 2 groups. The Unified Parkinson′s Disease Rating Scale (UPDRS) was used to evaluate the severity of the disease, and its third part (UPDRS-Ⅲ) was used to evaluate the motor function of the patients. Hamilton Rating Scale for Depression (HAMD) and Hamilton Rating Scale for Anxiety (HAMA) were used to evaluate the depression and anxiety status of the patients. The sleep status of patients was assessed by Parkinson′s Disease Sleep Scale (PDSS). The quality of life of the patients was assessed by 39-item Parkinson′s Disease Questionnaire (PDQ-39).Results:Of all the patients, 49.59% (60/121) had the body-first subtype and 50.41% (61/121) had the brain-first subtype of PD. There was no significant difference in UPDRS-Ⅲ score between the 2 groups. The average number of NMS in all PD patients was 10.97±4.88. Body-first subtype patients had higher NMS incidence than brain-first subtype in difficulty in swallowing [46.7% (28/60) vs 23.0% (14/61), χ 2=7.507, P=0.006], nausea and vomiting [16.7% (10/60) vs 3.3% (2/61), χ 2=6.069, P=0.014], constipation [85.0% (51/60) vs 55.7% (34/61), χ 2=12.393, P<0.001], fecal incontinence [8.3% (5/60) vs 0 (0/61), χ 2=5.302, P=0.021], difficulty in remembering recent events [58.3% (35/60) vs 32.8% (20/61), χ 2=7.962, P=0.005], loss of interest [43.3% (26/60) vs 24.6% (15/61), χ 2=4.743, P=0.029], inattention [45.0% (27/60) vs 19.7% (12/61), χ 2=8.884, P=0.003], depression [55.0% (33/60) vs 34.4% (21/61), χ 2=5.181, P=0.023], intense vivid dreams [73.3% (44/60) vs 39.3% (24/61), χ 2=14.196, P<0.001] and restless legs [53.3% (32/60) vs 27.9% (17/61), χ 2=8.140, P=0.004]. The differences were significant. Body-first subtype and NMSQuest ( r=-0.489, P<0.001), UPDRS ( r=-0.189, P=0.038), HAMD ( r=-0.231, P=0.011), HAMA ( r=-0.298, P=0.001) and PDQ-39 scores ( r=-0.276, P=0.002) were negatively correlated. Body-first subtype and PDSS score was positively correlated. NMSQuest (Δ R2=0.265, P<0.001) was the main determinant of PDQ-39 score. Conclusions:PD patients are accompanied by various NMS, which is a major factor affecting the quality of life. Compared with brain-first subtype, body-first subtype might have more NMS burden and higher incidence rate in most NMS in early PD patients.

Objective:To investigate the grey matter alterations of Parkinson′s disease (PD) patients with and without sleep disorders, and to explore the relationship between different sleep-related problems and clinical variables as well as grey matter volume (GMV) in PD.Methods:Forty-six PD patients and 38 healthy controls (HCs) were recruited from January 2018 to December 2021 in the Department of Neurology, Beijing Hospital. PD patients were divided into PD with sleep disorders (PD-S, n=26) and PD without sleep disorders (PD-nS, n=20) subgroups (cutoff points of 82 for Parkinson′s Disease Sleep Scale or less than 5 for each item was considered as an indicator of substantial sleep disorder). The Mini-Mental State Examination (MMSE), the third part of the Unified Parkinson′s Disease Rating Scale (UPDRS-Ⅲ), Hamilton Rating Scale for Anxiety (HAMA), Hamilton Rating Scale for Depression (HAMD), Non-Motor Symptoms Questionnaire (NMSQ), and Parkinson′s Disease Questionnaire-39 (PDQ-39) were used to evaluate cognitive function, motor symptoms, anxious and depressive symptoms, non-motor symptoms, and the quality of life of the patients. Optimized voxel-based morphometry was applied to the magnetic resonance imaging brain images in all participants,and multiple linear regression analysis was used to test the correlation between GMV and sleep quality in patients with PD. Results:Compared with the HCs, PD-nS patients showed decreased GMV in bilateral limbic lobe, parahippocampal gyrus, amygdala, cingulate gyrus, hippocampus, right cerebellum, bilateral frontotemporal lobe, bilateral occipital lobe and the left parietal lobe. PD-S group exhibited reduced GMV in bilateral limbic lobe, parahippocampal gyrus, amygdala, right cerebellum, bilateral frontotemporal lobe and bilateral parietal-occipital lobe, compared to the HCs. Compared with PD-nS, PD-S patients revealed higher depressive (HAMD score: 12.19±5.59 vs 6.95±3.19, t=-4.01, P<0.001), anxious (HAMA score: 12.04±5.32 vs 7.25±4.68, t=-3.18, P=0.003), and non-motor symptoms scores (NMSQ score: 12.92±5.18 vs 9.90±4.10, t=-2.14, P=0.038), poorer quality of life (PDQ-39 score: 35.31±22.01 vs 22.40±9.00, t=-2.71, P=0.010), and reduced GMV in the left insula, frontal, and parietal lobe ( P<0.001, uncorrected, cluster>100). There was a marked relationship between sleep quality and the reduced GMV of the right medial temporal gyrus (β=0.006, 95% CI 0.002-0.010, P=0.003), left middle frontal gyrus (β=0.006, 95% CI 0.002-0.010, P=0.002), the right cerebellum (β=0.014, 95% CI 0.005-0.023, P=0.003), and the right medial occipital gyrus (β=0.017, 95% CI 0.011-0.024, P<0.001). Significant grey matter changes were associated with nocturnal restlessness, mainly within the left limbic lobe, bilateral occipital lobe, the right cerebellum, and parietal lobe (β=0.008, 95% CI 0.006-0.010, P<0.001). Furthermore, nocturia in PD was related to certain grey matter atrophy, including bilateral limbic lobe, the right inferior parietal gyrus, and bilateral frontal lobe (β=0.010, 95% CI 0.008-0.013, P<0.001). The symptom of daytime dozing was correlated with GMV reduction in the right occipital lobe, the left temporal lobe (β=0.014, 95% CI 0.010-0.019, P<0.001). There were also several compensatory brain regions, including bilateral frontal lobe, the left limbic lobe and cingulate ( P<0.001, uncorrected, cluster>60). Conclusions:Sleep disturbance is common in PD, which is related to the anxious and depressive symptoms, non-motor symptoms, and the quality of life. PD patients with different sleep disorders show grey matter alterations in severeal brain regions, which are associated with sleep quality, nocturnal restlessness, psychosis, and daytime dozing.

Objective:To explore the relationship between sleep quality and depression among fertile women, and provide a scientific reference for protecting the mental health of fertile women.Methods:The study included 12 518 fertile women who were 15 to 49 years old from the Second Affiliated Hospital of Kunming Medical University and Maternal and Child Health Hospital of Qujing in Yunnan Province from January 2019 to November 2019. Sleep quality was collected by using self-reported questionnaires, and depression was evaluated by using the Edinburgh Postpartum Depression Scale. We used logistic regression to analyze the relationship between sleep quality and depression after controlling for other factors.Results:Among 12 518 fertile women, 3197 had poor sleep quality which accounted for 25.54% (95% CI=24.77%-26.30%). The detection rate of depression was 55.59% (6959/12 518; 95% CI=54.72%-56.46%). The detection rate of depression of the poor sleep quality group [75.40% (2410/3197)] was significantly higher than that of the good sleep quality group [48.80% (4549/9321), P<0.001]. Multivariate logistic regression analysis showed that after controlling for basic demographic characteristics, health status, lifestyle habits and other factors, depression was still associated with poor sleep quality (a OR=3.28, 95% CI=2.99-3.60; P<0.001). Conclusion:The problem of depression and sleep quality on fertile women cannot be ignored, and sleep quality was associated with depression significantly which suggested that it was necessary to keep good life style, improve sleep quality and promote mental health.
