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 investigate the effect of blood glucose control parameters on the prognosis of severe pneumonia patients based on continuous glucose monitoring(CGM)system.Methods A retrospective analysis was conducted on 51 severe pneumonia patients monitored by CGM at the Fourth Affiliated Hospital of Soochow University from November 2021 to August 2023.Assessed parameters included baseline clinical characteristics,glycosylated hemoglobin(HbA1c),mean glucose,standard deviation(SD),coefficient of variability(CV),mean amplitude of glycemic excursions(MAGE),maximum glucose level,minimum glucose level,and time in range(TIR)of glucose within the target range(3.9-10.0 mmol/L)as a proportion and levels of inflammatory indicators before and after treatment.Based on the 28-day follow-up results,the patients were divided into the survival group(39 cases)and the death group(12 cases).The blood glucose parameters of the two groups were compared.Multivariate Logistic regression model was used to analyze the influence of blood glucose parameters and infection indexes on the prognosis of patients with severe pneumonia.The efficacy of blood glucose parameters in the diagnosis of 28-day mortality was further evaluated by receiver operator characteristic curve(ROC curve).Results The acute physiology and chronic health evaluationⅡ(APACHEⅡ),SD and CV of blood glucose in death group were higher than those in survival group[APACHEⅡscore:20.5(14.0)vs.15.0(7.0),SD(mmol/L):2.6±0.7 vs.2.1±0.5,CV:(27.7±5.8)%vs.(23.7±4.3)%].However,the TIR(3.9-10.0 mmol/L)proportion was statistically lower than that of survival group[59.0%(17.0%)vs.68.0%(35.0%)],the differences were all statistically significant(all P<0.05).After using CGM,the white blood cell count(WBC)and hypersensitive C-reactive protein(hs-CRP)were significantly decreased[WBC(×109/L):9.2(6.5)vs.11.1(9.2),hs-CRP(mg/L):39.4(59.0)vs.56.2(133.8),both P<0.05].Multivariate Logistic regression showed that TIR(3.9-10.0 mmol/L)proportion was an independent risk factor for 28-day mortality in patients with severe pneumonia[odds ratio(OR)=0.923,95%confidence interval(95%CI)was 0.852-0.999,P=0.046].The ROC curve showed that TIR proportion was valuable in predicting the clinical outcomes of patients with severe pneumonia.Area under the curve(AUC)=0.720,95%CI was 0.563-0.878,P=0.022;when the cut-off value was 63.5%,the sensitivity and the specificity were 59.0%and 83.3%respectively.Conclusion Increase of TIR(3.9-10.0 mmol/L)proportion in patients with severe pneumonia could improve clinical outcomes,especially when TIR proportion≥63.5%.

Objective To investigate the effect of dexmedetom idine(DEX)on lung tissue and Ras homolog gene family member A(RhoA)/Rho kinase 1(ROCK1)signaling pathway in lung tissue of rats with ventilator-induced lung injury(VILI).Methods A VILI rat model was established and separated into control group,model group(VILI group),dexmedetomidine low and high dose groups(DEX-L,DEX-H group),and high dose dexmedetomi-dine+lysophosphatidic acid(LPA)group(DEX-H+LPA group).Determination of wet/dry mass ratio of rat lung tissue(W/D);HE staining microscopy was applied to observe morphology of lung tissue;ELISA kit was applied to detect the level of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and interleukin-6(IL-6)in bronchoalveolar lavage fluid(BALF);TUNEL staining method was applied to detect lung epithelial cell death;Immunoblotting was applied to detect the expression levels of apoptosis-related proteins,and RhoA,ROCK1 pro-teins.Results DEX could reduce lung injury,lung injury score,W/D,apoptosis rate,levels of TNF-α,IL-1β,IL-6,and expression of Bax,cleaved caspase-3,RhoA,ROCK,α-SMA in VILI rats(P＜0.05),while increased the expression of Bcl-2(P＜0.05);LPA could aggravate lung injury and increase lung injury score,W/D,apopto-sis rate,level of TNF-α,IL-1β,IL-6 and expressions of Bax,cleaved caspase-3,RhoA,ROCK and α-SMA(P＜0.05);Bcl-2 expression level was decreased(P＜0.05).Conclusions Dexmedetomidine may protect rats with ventilator-induced lung injury by the inhibition of RhoA/ROCK1 signaling pathway.

Objective To explore the prescription rules of traditional Chinese medicine (TCM) in the treatment of diabetes periodontitis(DP) and the acting mechanisms of core drug combination. Methods Based on the relevant literature retrieved from the CNKI,Wanfang,VIP and Sinomed,a DP prescription database was established. Excel 2021,SPSS Modeler 18.0 and SPSS Statistics 26.0 were used to conduct the statistics of the frequency,efficacy classifications,properties,flavors,and meridian tropism of the included drugs. Association rule analysis and cluster analysis were performed to screen out the core drug combinations. The active components and action targets of core drug combinations were obtained through TCMSP and HERB. The DP related disease targets were predicted using GeneCards. The Venny platform was used to obtain the intersection of disease targets and drug targets. Key components were screened by Cytoscape to establish an "active component-target" network. Based on STRING platform data,PPI network was constructed by Cytoscape to screen core targets. GO functional annotation and KEGG signaling pathway enrichment analysis were carried out for the intersection targets by DAVID. AutoDockVina was applied for molecular docking between core targets and key components. Results A total of 36 articles were included,and 50 prescriptions involving 100 Chinese herbal medicines were extracted. Alismatis Rhizoma,Rehmanniae Radix Praeparata and Astragali Radix were the most common drugs. The most used drug category was deficiency-nourishing drugs. The properties of the herbs were mainly cold and warm,the major flavors were sweet and bitter,and the main meridian tropisms were kidney and liver. Six categories were classified by clustering analysis. Moutan Cortes-Corni Fructus-Rehmanniae Radix Praeparata was screened out as the core drug combination involving 18 active components,164 drug action targets and 104 intersection of DP targets and drug combination targets. Quercetin,stigmasterol,kaempferol,β-sitosterol,tetrahydroalstonine,and sitosterol were the key components,and AKT1,IL-6,TNF,IL-1B,PTGS2,JUN,TP53,ESR1,and MMP9 were the core targets. GO analysis revealed 3724 biological processes,228 cellular components and 404 molecular functions. KEGG analysis showed that DP was treated by the core drug combination through regulating 235 signaling pathways. Molecular docking results showed that there was a good affinity between the core target and the key component. Conclusion Tonifying deficiency is the main treatment methods of TCM for DP,accompanied by clearing heat and removing dampness,activating blood circulation and removing blood stasis,replenishing qi and nourishing yin. Core drug combination (Moutan Cortes-Corni Fructus-Rehmanniae Radix Praeparata) treats DP through multi-component,multi-target and multi-pathway,which provide a reference for clinical diagnosis and treatment.

Objective:To retrospectively summarize the clinical characteristics and treatment of 49 patients with hyperthyroid cardiopath and to explore the diagnosis and treatment methods of hyperthyroid cardiopathy.Methods:A total of 49 patients with hyperthyroid cardiopath(HC group) who were successfully treated and followed up in the Department of Endocrinology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, from January 2016 to December 2021 were collected, and 85 cases of Graves′ disease without heart disease were collected as the control group(GD group). The medical history, laboratory tests, and echocardiographic parameters of the two groups were compared. Differences in thyroid and cardiac indicators before and after treatment in the HC group were summarized, along with the dosage of β-receptor blockers used in treating different types of conditions(atrial fibrillation and heart failure.Results:Patients in the HC group were older and had a longer duration of hyperthyroidism than those in the GD group( P<0.001, P=0.002). There were no significant differences in thyroid hormone levels between the two groups except for reverse triiodothyronine(rT 3). Age and rT 3 were independent risk factors of hyperthyroid cardiopathy. rT 3 level was linearly positively correlated with brain natriuretic peptide, systolic pulmonary artery pressure, left artrium diamete (LAD) and left ventricular end-systolic diameter(LVDs; r=0.352, P<0.001; r=0.392, P=0.019; r=0.202, P=0.029; r=0.242, P=0.028). In patients of HC group, free triiodothyronine(FT 3) level returned to normal range after 2.87(1.63, 5.53) months of treatment with radioiodine(41/49) or antithyroid drugs(8/49), while brain natriuretic peptide, LAD, LVDs, and systolic pulmonary artery pressure declined after 5.00(1.25, 8.00) months of treatment. Non-selective β-receptor blockers were used for both hyperthyroid heart failure and atrial fibrillation, and there was no statistically significant difference in dosage[(86.52±47.83)mg vs(88.67±47.19)mg, P>0.05]. Conclusions:rT 3 may be a biomarker of hyperthyroid cardiopath and indicate the severity of hyperthyroidism. β-receptor blockers are crucial in treating patients with hyperthyroidism who develop atrial fibrillation and heart failure.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

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 characteristics and clinical related factors of Parkinson′s disease (PD) patients with subjective cognitive decline (SCD).Methods:Ninety-nine PD patients with normal cognitive function enrolled in Beijing Hospital from January to December 2018 were collected for the study. Patients with PD were divided into groups with ( n=57) and without ( n=42) SCD using the first question in Part 1 of the Unified Parkinson′s Disease Rating Scale (UPDRS). All patients were assessed by Montreal Cognitive Assessment (MoCA), modified Hoehn-Yahr grading, UPDRS, Hamilton Rating Scale for Depression (HAMD), Hamilton Rating Scale for Anxiety (HAMA), Parkinson′s Disease Sleep Scale, Ability of Daily Living Scale and 39-item Parkinson′s Disease Questionnaire (PDQ-39). Levodopa equivalent dose conversion was performed for patients taking anti-PD drugs. Patients′ self-reported years of formal education were collected. Results:The proportion of PD with SCD in this group was 57.58% (57/99). There were statistically significant differences in MoCA [28.00 (27.00, 29.00) vs 28.00 (27.00, 29.00) ,Z=-2.28, P=0.023], HAMD [6.00 (5.00, 8.50) vs 5.00 (2.00, 8.00), Z=-2.23, P=0.026], HAMA [7.00 (6.00, 11.00) vs 6.00 (3.00, 8.25) , Z=-2.70, P=0.007], PDQ-39-emotional health [2.00 (0, 5.00) vs 1.00 (0, 3.00), Z=-2.03, P=0.042] and PDQ-39-cognitive scores [4.00 (2.00, 5.00) vs 2.00 (0, 4.00), Z=-3.42, P=0.001] between PD with and without SCD groups. SCD was correlated with MoCA ( r=-0.23, P=0.022), HAMD ( r=0.23, P=0.025) and HAMA ( r=0.27, P=0.006) scores to varying degrees. When controlling for HAMD and HAMA scores, the correlation between SCD and MoCA scores ( r′=-0.18, P=0.084) was no longer existed. Conclusions:SCD is common in PD patients with normal cognitive function and is associated with poorer cognitive performance and more severe symptoms of depression and anxiety. In this group of patients, the relationship between SCD and affective symptoms may be greater than that of objective overall cognitive function, which is worthy of further studies.
