Amyotrophic lateral sclerosis (ALS) is a chronic, progressive degenerative disease affecting both upper and lower motor neurons, primarily characterized by skeletal muscle weakness and atrophy. Notably, the same muscle group may exhibit asynchronous involvement. This study aims to investigate the involvement patterns of the orbicularis oculi (OOc) and orbicularis oris (OOr) in ALS patients, compare the findings with healthy controls (HCs) and myasthenia gravis (MG) patients, and explore the characteristics and clinical significance of facial muscle involvement in ALS.

Poly(ADP-ribose) polymerase 1 (PARP1) is a multifunctional protein involved in diverse cellular functions, notably DNA damage repair. Pharmacological inhibition of PARP1 has therapeutic benefits for various pathologies. Despite the increased use of PARP inhibitors, challenges persist in achieving PARP1 selectivity and effective blood-brain barrier (BBB) penetration. The development of a PARP1-specific positron emission tomography (PET) radioligand is crucial for understanding disease biology and performing target occupancy studies, which may aid in the development of PARP1-specific inhibitors. In this study, we leverage the recently identified PARP1 inhibitor, AZD9574, to introduce the design and development of its ¹⁸F-isotopologue ([¹⁸F]AZD9574). Our comprehensive approach, encompassing pharmacological, cellular, autoradiographic, and in vivo PET imaging evaluations in non-human primates, demonstrates the capacity of [¹⁸F]AZD9574 to specifically bind to PARP1 and to successfully penetrate the BBB. These findings position [¹⁸F]AZD9574 as a viable molecular imaging tool, poised to facilitate the exploration of pathophysiological changes in PARP1 tissue abundance across various diseases.

OBJECTIVE To investigate the result of human immunodeficiency virus(HIV)screening for the people visiting to a three-A hospital of Sichuan Province and analyze the prevalence of complications with hepatitis B virus(HBV)infection,hepatitis C virus(HCV)infection and Treponema pallidum(TP)infection in the emerging HIV infection patients.METHODS The result of HIV screening for the people who visited to Ziyang Central Hos-pital from Jan.1,2020 to Dec.31,2024 and the test results of HBV,HCV and TP for the emerging HIV infec-tion patients were collected and were summarized and statistically analyzed by SPSS.0 software.RESULTS Totally 289 891 case-times were tested for HIV,1529 cases were previously diagnosed with HIV,465 of whom were tested posi-tive for the first time,there was significant difference in the positive rate of test for the first time among the 5 years(x2=15.998,P=0.003).Totally 353 cases were confirmed positive among the 465 primary positive screening cases.Among the emerging HIV infection patients,the positive rate was higher in the male than in the female(x2=141.141,P＜0.001),and the positive rate was high among the population aged more than 40 year old(x2=11.448,P＜0.001),mi-grant workers(x2=270.110,P＜0.001)and low education level population(x2=25.911,P＜0.001).The detection rate of gp41 was up to 100.00％in strip type testing.The analysis of the ratio of relative light unit(RLU)to Cutoff val-ue(COI)in the initial screening experiment showed that when COI was greater than 50,all of the confirmed tests were positive,when COI ranged between 1 and 5,the false positive rate was 97.06％.The incidence of complica-tion with HBV infection in the emerging HIV infection patients was increased year by year(x2=20.355,P＜0.001),and the incidence of complication with HCV infection was increased in recent two years(x2=10.690,P=0.030).CONCLUSIONS There is no obvious rise of positive rate of HIV screening among the people visiting to the hospital in recent 5 years.The sensitivity of the primary screening of clinical laboratory is high without posi-tive missing test.The positive rates of HBV and HCV are increased among the emerging HIV infection patients.

Objective:To observe the effects of acupuncture on the motor function of Parkinson disease(PD)model mice and to investigate the neuroprotective effects of acupuncture on PD from the perspective of cellular senescence.Methods:C57BL/6J mice were randomly divided into a normal control(NC)group,a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)group,an acupuncture(ACU)group,and a rasagiline(RAS)group,with 6 mice in each group.Except for the mice in the NC group,all mice were injected intraperitoneally with MPTP[30 mg/(kg·bw)]to establish a PD mouse model.After the models were successfully established,mice in the ACU group received acupuncture at Baihui(GV20)and bilateral Yanglingquan(GB34)for 15 min,once a day for 14 consecutive days.Mice in the RAS group were treated with gavage of rasagiline mesylate[0.5 mg/(kg·bw)],once daily for 14 d.Mouse balance and motor functions were detected using the mouse fatigue rotating rod apparatus.Immunohistochemistry staining was used to detect the number of tyrosine hydroxylase(TH)-positive neurons and the protein expression levels of special AT-rich sequence-binding protein 1(SATB1),p21,and p53 in the substantia nigra(SN)region of the mouse brain in each group.The glutathione peroxidase(GSH-Px)activity of mouse brain SN tissue was detected by enzyme-linked immunosorbent assay.The protein expression levels of interleukin(IL)-6 and senescence-associated β-galactosidase(SA-β-gal)in the SN tissue of mice in each group were detected by Western blotting.The relative expression of SATB1,p21,and p53 mRNA in the SN of each group was detected by real-time quantitative polymerase chain reaction.Results:Compared to the NC group,the overall rod performance(ORP)score,the number of TH-positive neurons,and GSH-Px activity in the SN region were significantly lower in the mice in the MPTP group(P<0.01);compared to the MPTP group,the ORP score,the number of TH-positive neurons,and GSH-Px activity were significantly increased in the ACU group and the RAS group(P<0.01 or P<0.05).Compared to the NC group,the protein levels of IL-6 and SA-β-gal in the SN tissue,the protein and mRNA expression levels of p21 and p53 were significantly increased(P<0.01);compared to the MPTP group,the protein levels of IL-6 and SA-β-gal in the SN tissue,the protein and mRNA expression levels of p21 and p53 were significantly decreased in the ACU group and the RAS group(P<0.01 or P<0.05).Compared to the NC group,the relative expression of SATB1 protein and mRNA in the SN of mice in the MPTP group was significantly decreased(P<0.01);compared to mice in the MPTP group,mice in the ACU group and the RAS group showed significant increases in the relative expression of SATB1 protein and mRNA(P<0.01 or P<0.05).Conclusion:Acupuncture can improve motor function and increase the number of TH-positive neurons in the SN of PD model mice.Its neuroprotective effect may relate to the regulation of the SATB1/p21 signaling pathway and the inhibition of cellular senescence-related biomarker expression in the SN.

Inflammatory bowel disease (IBD) is a chronic, relapsing intestinal disorder driven by multiple factors including genetics, immunity, and environment, and is clinically classified into ulcerative colitis and Crohn's disease. Currently, mice and zebrafish are the primary experimental animals used in IBD research, among which zebrafish have emerged as an ideal model due to their unique advantages. Compared with rodent models, zebrafish serve as an effective and convenient model, offering advantages such as a short life cycle, robust reproductive capacity, small size, and transparent embryos. These characteristics make zebrafish highly suitable for dynamic tracking of continuous pathological progression and high-throughput drug screening. Zebrafish share over 70% genetic homology with humans, and their intestinal cellular composition and ontogeny closely resemble those of humans. Moreover, the structure and characteristics of their gut microbiota are similar to the human intestinal microbiome, providing a solid foundation for studying the relationship between gut microbiota and IBD. With advances in biotechnology, zebrafish IBD models generated by chemical induction or genetic engineering can accurately simulate the core pathological features of human IBD, such as intestinal wall thickening, inflammatory cell infiltration, and elevated expression of pro-inflammatory factors. These models have played a significant role in revealing the pathogenesis of IBD as well as the development of targeted therapeutic drugs. This article first outlines the intestinal characteristics of zebrafish and features of zebrafish IBD models, then provides an in-depth analysis of their application in IBD pathogenesis research from multiple aspects, including genetics, immunity, environment and diet, and infection. It also reviews research progress on the application of zebrafish in the development of anti-inflammatory drugs, probiotics, and traditional Chinese medicine therapies, aiming to provide researchers with references for the rational use of zebrafish models at all stages of preclinical research, to advance fundamental IBD research and accelerate breakthroughs in this field.

Objective:To compare the effects of standard cognitive behavioral therapy for insomnia (CBT-I) and enhanced cognitive behavioral therapy for insomnia(CBT-I Plus) in patients with chronic insomnia disorder comorbid anxiety or depressive symptoms.Methods:This prospective study included 148 patients with chronic insomnia disorder and anxiety/depression symptoms who were treated at the Sleep Disorder clinic of Shanghai Mental Health Center between July 2020 and August 2023. Participants (56 males, 92 females; aged 18-65 years, mean age 35.08±10.30 years) were randomly assigned in a 1∶2 ratio to the CBT-I group ( n=54) or CBT-I Plus group ( n=94). The CBT-I Plus group received additional treatments targeting anxiety and depressive symptoms. Treatment lasted 8 weeks, with assessment conducted at baseline, weeks 2, 4, and 8. Depression severity was measured using the 17-item Hamilton Depression Rating Scale (HAMD 17), anxiety severity with the Hamilton Anxiety Scale (HAMA), and sleep quality with the Pittsburgh Sleep Quality Index (PSQI). Paired sample t-tests were used to evaluate within-group changes, repeated-measures ANOVA compared treatment effects between groups, and ANCOVA was employed to adjust for confounding variables. Results:Significant reductions in PSQI, HAMD 17, and HAMA scores were observed in both groups after treatment: CBT-I group: PSQI ((14.15±2.54) vs. (7.50±3.35), t=13.25), HAMD 17 ((14.70±4.09) vs. (7.40±4.61), t=9.33), and HAMA ((14.94±4.11) vs. (5.56±3.67), t=12.38) (all P<0.001).CBT-I Plus group: PSQI ((14.87±3.01) vs. (7.19±3.86), t=18.75), HAMD 17 ((16.84±3.91) vs. (6.84±4.79), t=17.42), and HAMA ((15.57±3.93) vs. (6.10±4.57), t=18.39) (all P<0.001). After adjusting for HAMD 17 scores and medication use, no statistically significant between-group differences were observed in changes in PSQI, HAMD 17, and HAMA scores ( P>0.05). A significant time-by-group interaction was found for the PSQI daytime dysfunction subscale ( F=4.87, P<0.01). Conclusion:Both CBT-I and CBT-I Plus improve sleep and emotional symptoms in patients with chronic insomnia disorder and comorbid anxiety/depression symptoms. However, CBT-I Plus has no significant advantages over standard CBT-I. Further studies are needed to refine the timing and content of interventions.

Objective To investigate the distribution characteristics of Klebsiella pneumoniae(KP),hyperviru-lent Klebsiella pneumoniae(hvKP),carbapenem-resistant Klebsiella pneumoniae(CRKP),and hypervirulent car-bapenem-resistant Klebsiella pneumoniae(hv-CRKP/CR-hvKP)in the environment of general intensive care unit(ICU)at medical institutions,and provide reference for environment assessment as well as healthcare-associated in-fection(HAI)prevention and control in ICU.Methods A total of 3 336 environmental specimens were collected from general ICUs of medical institutions in Shanghai in 2019 and 2023.After strain isolation,antimicrobial suscep-tibility testing and whole genome sequencing were conducted.Results The detection rate of KP was 1.59％(n=53),among which hvKP,CRKP,and hv-CRKP/CR-hvKP accounted for 37.74％(20/53),52.83％(28/53),and 24.53％(13/53)of the total detected strains,respectively.The main types of hvKP were ST11-KL64 and ST11-KL25,CRKP were ST15-KL19 and ST11-KL25,hv-CRKP/CR-hvKP were ST11-KL25 and ST11-KL64.The main carried resistance genes included fosA,oqx AB,tet(A),blaTEM-1B,blaKPC-2,qnrS11,etc.All strains carried viru-lence genes fimH,iutA,ent A,entB,entC,entD,entE,and entF,with only one strain carrying rmp A gene.Conclusion KP contamination is widespread in general ICU environment of medical institutions,predominantly ST11 and ST15,presenting a polymorphic distribution.CRKP and hvKP account for a relatively high proportion,and multidrug resistance is serious.Co-evolution of drug resistance and virulence presents in KP,and poses signifi-cant infection and pathogenic risks to patients,necessitating enhanced clinical vigilance and preparedness for poten-tial outbreaks.

Objective Exploring the clinical diagnosis and treatment status of epilepsy patients at the epilepsy specialty clinic in a single-center comprehensive hospital in the Lhasa area of the Tibetan Plateau.Methods Epilepsy patients who visited the epilepsy specialty clinic of the Department of Neurology at the Tibet Autonomous Region People's Hospital from September 2021 to June 2023 were continuously enrolled.Data such as clinical characteristics and diagnosis and treatment conditions of the enrolled patients was analyzed.Results A total of 121 patients were enrolled in this study,with 33.9%(41/121 cases)being new patients at our hospital and 6.6%(8/121 cases)being referred to our hospital.Non-adherence to treatment,with patients self-reducing or stopping medication without medical advice,accounted for 8.3%(10/121 cases)of the cases.The majority of epilepsy patients were in the young and middle-aged group,with 51.2%(62/121 cases)being between 18 and 44 years old.There were significant differences in the distribution of epilepsy patients across different age groups(P<0.001),while there was no significant difference in gender distribution(49.6%male vs.50.4%female,P>0.05).Generalized seizures were the predominant type of seizure(75.2%,91/121 cases),and 73.6%(89/121 cases)of the patients had an unknown etiology for their epilepsy,with symptomatic epilepsy accounting for 26.4%(32/121 cases)and structural causes being the most common at 24.8%(30/121 cases).Monotherapy was the main treatment for epilepsy(55.4%,67/121 cases),with sodium valproate being the most frequently prescribed drug for monotherapy at 22.3%(27/121 cases).Conclusion In the epilepsy specialty clinic in the plateau region,newly diagnosed patients account for about one-third,and over one-tenth of revisiting patients have not been receiving standardized treatment.The majority of our epilepsy patients are young to middle-aged adults.Generalized seizures are the predominant type.The etiology is unknown in the majority of cases,with structural causes being a common etiology in symptomatic epilepsy.Sodium valproate is the most frequently used antiseizure medication(ASM)in monotherapy in the plateau area.
