Spondyloarthritis (SpA) is a group of chronic inflammatory diseases which predominantly involve spine and/or peripheral joints. SpA can be disabling and seriously affect the quality of life and function of patients. With the increasing clinical use of targeted drug therapy, precise and standardized use becomes the focus. China's first Consensus on Targeted Drug Therapy for Spondyloarthritis was developed by National Clinical Research Center for Dermatologic and Immunologic Diseases using international norms for consensus development. The consensus addresses 13 important clinical questions, ranging from principles, patient eligibility, pre-treatment screening, treatment initiation, drug selection and switch, co-medication, to adverse event monitoring of targeted drug therapy in SpA, and recommends treatment for specific patients, playing a key role in guiding clinical practices.

Objective To analyze the quality of life and its influencing factors among patients with occupational coal workers' pneumoconiosis (hereinafter referred to as "coal workers' pneumoconiosis"). Methods A total of 404 coal workers' pneumoconiosis patients diagnosed in Fengjie County of Chongqing City were selected as the study subjects using the convenient sampling method, and their quality of life was investigated by the SF-36 scale. Results The total score of quality of life of the subjects was (63.1±12.1) points. Their scores in the eight dimensions of physical functioning, role-physical, bodily pain, general health subscales, vitality, social functioning, role-emotional, and mental health subscales were lower than that of norms for Chongqing City and the nation (all P<0.05). The results of multiple linear regression analysis showed that the total score of quality of life of the patients decreased with the increase of age and stage of pneumoconiosis (all P<0.01). The total score of quality of life of patients living in urban areas was higher than that of rural patients(P<0.01). The total score of quality of life of patients who had left their jobs was higher than that of retired patients (P<0.01). The total score of quality of life of smoking patients and those with complications was lower than that of non-smokers and those without complications (all P<0.01). Conclusion Age, place of residence, smoking, stage of pneumoconiosis, work status, and complications of pneumoconiosis were the main influencing factors of quality of life among coal workers' pneumoconiosis patients.

Objective To investigate the vowel acoustic characteristics of patients with voice disorders and the reasonable way of administering vocal space area(VSA)and language in the Mandarin system.Methods A total of 40 subjects(20 males and 20 females)with voice disorder and normal healthy controls were recruited.The differ-ences in VSA between the disorder and healthy control groups were analyzed under different corpora and different vowel vertex numbers.Results The differences in VSA between the voice disorder and the control groups were highly significant in both the vowel and long sentence corpus.The differences in VSA between 4 vowels and 3 vow-els and 5 vowels were not significant,and 5 vowels were more suitable for VSA measurement in Mandarin.Conclu-sion The vowel articulation of patients with voice disorder is less clear than that of normal speakers.It is more ac-curate to use 5 vowels to measure VSA under the Mandarin system and it is better for measuring oral motility.Both single vowels and continuous speech are suitable for the measurement of VSA.

Objective To investigate the characteristics of oral and laryngeal diadochokinesis abilities and the developmental patterns of coordinated vocal fold movements in preschool children aged 3～6 years.Methods Sixty-one normal preschool children aged 3～6 years were selected to measure their maximum phonation time(MPT),as well as two types of acoustic parameters of oral and laryngeal diadochokinesis ability movements,including the as-sessment of one trisyllabic/pataka/diadochokinesis ability rate and four monosyllabic/?a/,/ha/,/?A/,/hA/la-ryngeal diadochokinesis ability rates.Results Diadochokinesis ability(DDK)and laryngeal diadochokinesis ability(LDDK)rates increased with age in preschool children aged 3～6 years,showing highly significant differences(P＜0.01).The growth rate of children's LDDK rates at age 4～5 years was the maximum within the 3～6 year age range.Children's MPT was highly significantly and positively correlated with DDK and LDDK(P＜0.01).The vo-cal fold adduction capacity in laryngeal diadochokinesis ability movements in children of all age groups was greater than vocal fold adduction ability/?a/LDDK＞/ha/LDDK(P＜0.01),/?A/LDDK＞/h∧/LDDK(P＜0.05).Con-clusion Age,MPT,and vocal fold adduction and abduction status had a significant effect on the oral and laryngeal diadochokinesis ability of preschool children aged 3～6 years old.The ages of 4～5 is a critical period for the devel-opment of children's oral and laryngeal diadochokinesis ability.

AIM:To establish a severe pneumonia mouse model induced by bacterial infection.METHODS:A total of 102 male SPF C57BL/6J mice were randomly divided into a control group and a model group.Klebsiella pneu-moniae was administered via tracheal instillation at a concentration of 5×109 CFU.Mice were euthanized on days 1,2,4,8,and 14 post-infection to assess general condition,body weight,mortality,white blood cell and neutrophil counts,in-flammatory markers,and pathological changes in lung,heart,liver,spleen,kidney,and intestinal tissues.RESULTS:Mice in the model group exhibited symptoms such as dyspnea and huddling from 6 hours to 4 days post-infection,which progressively worsened,accompanied by continuous weight loss(P<0.01).These symptoms gradually resolved between days 5 and 14.Arterial oxygen saturation in the model group dropped to 80.7%from days 1 to 8(P<0.01)but returned to normal from days 9 to 14.A total of 23 model mice died between days 1 and 9,with no deaths thereafter,resulting in a mortality rate of 31.9%(P<0.01).Pathological examination revealed inflammatory cell infiltration,congestion,and ede-ma in lung tissue from days 1 to 2,with continued inflammatory cell infiltration,alveolar structural disorganization from days 4 to 8,and alveolar rupture and fusion by day 14(P<0.05 or P<0.01).Additionally,model mice showed significant increases in neutrophil count,white blood cell count,protein content in bronchoalveolar lavage fluid,total cell count,neutrophil ratio,and levels of inflammatory factors tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and IL-6 in peripheral blood from days 1 to 8(P<0.05 or P<0.01).No significant pathological changes were observed in heart and liver tissues,while spleen,kidney,and intestinal tissues exhibited notable pathological changes:indistinct boundaries be-tween red and white pulp in the spleen,significant congestion and edema around renal glomeruli,renal tubules,and col-lecting ducts,and extensive inflammatory cell infiltration in the colonic mucosa.CONCLUSION:Tracheal instillation of 5×109 CFU Klebsiella pneumoniae induces severe pathological changes in the lungs of mice,offering a robust model for studying the pathogenesis and treatment of severe pneumonia.

How medical resources can be fairly distributed in a public health emergency such as COVID-19. There have been mature or comparatively mature studies on this issue in both traditional ethics and contemporary ethics: the traditional ethics has the "maximum happiness principle" represented by utilitarianism, while the contemporary ethics has the new principle doctrine and the medical justice theory, which respectively put forward the methods suitable for the distribution of emergency medical resources, and defended their respective theories from different perspectives. However, when COVID-19 broke out, the actual medical resource distribution methods were still the traditional medical resource distribution methods, but did not use the contemporary mainstream ethical medical distribution approach, which was due to the limitations of the emerging medical ethics distribution theory. Therefore, in order to better provide ethical services to the medical and health field, the contemporary emerging theory of distribution of health care needs to introduce global bioethics, with its tolerance and respect, give full play to its advantages, and improve its shortcomings, so as to solve the problem of medical resources distribution.

Objective:To investigate the cause of death, survival time, and risk factors in patients diagnosed with Alzheimer′s disease (AD) at memory clinic.Methods:The patients with AD were enrolled from the memory clinic at Huashan Hospital, Fudan University between August 2002 and December 2006. Baseline data were collected and 7 rounds of telephone follow-up visits were conducted to track clinical outcomes. For death cases, the date and cause of death were recorded. Patients were divided into several subgroups based on gender and baseline cognition [Mini-Mental State Examination (MMSE) score]. Kaplan-Meier analysis and Cox proportional hazards regression models were constructed to analyze the survival time of patients and identify the risk factors.Results:A total of 499 patients were enrolled, including 199 males and 300 females. The follow-up time was 5.5(3.4,7.4) years, with longest follow-up time of 19.3 years. The median survival time after symptom onset was 11.8 years (95% CI 10.2-13.4 years), which was 12.4 years (95% CI 11.2-13.5 years) in females, significantly longer than that in males (10.2 years, 95% CI 9.6-10.8 years, logrank test, P=0.010). The median survival time after diagnosis was 8.3 years (95% CI 7.3-9.4 years), which was 8.8 years (95% CI 6.9-10.6 years) for women, significantly longer than that for men (6.8 years, 95% CI 5.7-7.9 years, logrank test, P=0.001). Patients with baseline MMSE scores≥15 ( n=265) had a median survial of 11.4 years (95% CI 9.5-13.2 years), significantly longer than those with poorer cognitive function (baseline MMSE scores<15; n=234, 7.4 years, 95% CI 6.4-8.4 years, logrank test, P<0.001). Multivariable Cox proportional hazards regression analysis showed that aging ( HR=1.027, 95% CI 1.002-1.052, P=0.034), lower body mass index (BMI; HR=1.081, 95% CI 1.023-1.139, P=0.007), lower baseline MMSE score ( HR=1.056, 95% CI 1.026-1.086, P<0.001), diabetes ( HR=1.716, 95% CI 1.076-2.735, P=0.023), and history of falls ( HR=1.536,95% CI 1.007-2.341, P=0.046) were independent risk factors for death (all P<0.05). During the follow-up, 224 of the participants died. Except for 62 cases of unknown reason, the top 6 causes of death were pneumonia (39 cases, 24.1%), cerebrovascular disease (24 cases, 14.8%), circulatory system disease(21 cases, 13.0%), multi-organ failure (17 cases, 10.5%), tumor (13 cases, 8.0%), eating disorders and malnutrition (13 cases, 8.0%). Conclusions:In the current study, the median survival time after onset for patients with AD was 11.8 years; aging, lower BMI, lower baseline cognition, comorbidities, and history of falls were independent risk factors for death; pneumonia was the most common cause of death.

The nucleus accumbens (NAc) plays an important role in various emotional and motivational behaviors that rely on heightened wakefulness. However, the neural mechanisms underlying the relationship between arousal and emotion regulation in NAc remain unclear. Here, we investigated the roles of a specific subset of inhibitory corticotropin-releasing hormone neurons in the NAc (NAc^CRH) in regulating arousal and emotional behaviors in mice. We found an increased activity of NAc^CRH neurons during wakefulness and rewarding stimulation. Activation of NAc^CRH neurons converts NREM or REM sleep to wakefulness, while inhibition of these neurons attenuates wakefulness. Remarkably, activation of NAc^CRH neurons induces a place preference response (PPR) and decreased basal anxiety level, whereas their inactivation induces a place aversion response and anxious state. NAc^CRH neurons are identified as the major NAc projection neurons to the bed nucleus of the stria terminalis (BNST). Furthermore, activation of the NAc^CRH-BNST pathway similarly induced wakefulness and positive emotional behaviors. Taken together, we identified a basal forebrain CRH pathway that promotes the arousal associated with positive affective states.
