OBJECTIVE To analyze the diagnosis of latent tuberculosis infection(LTBI)in hospitalized patients of a tertiary general hospital and investigate the current status of related comorbidities.METHODS The clinical data were collected from the 14 448 hospitalized patients who received tuberculin skin test(TST)or interferon-gamma release assay(IGRA)in China-Japan Friendship Hospital from Jan.1,2022 to Dec.31,2023,and the results were assessed.RESULTS The detection rate of LTBI was 23.62％(3413/14448)among the hospitalized patients who received the tests,and the rate of definite diagnosis was only 4.22％(144/3413).88.40％(3017/3413)of the hospitalized patients with LTBI had at least one type of comorbidity,and the top 5 comorbidities were in turn as follows:high blood pressure,hyperlipidemia,diabetes mellitus,malignant tumors and rheumatic immune disea-ses;the number of comorbidities was increased with the age(x2=291.199,P＜0.001).The rheumatic immune disease(73/144,50.69％)was the most common type of comorbidity among the hospitalized patients with definite diagnosis of LTBI,and less than half of the patients(66/144,45.83％)were treated in rheumatology and immu-nology department.CONCLUSION The two-way screening of LTBI and comorbidities is the core premise for the standardized management of LTBI.

Objective:To compare the clinical efficacy of a fixed exoskeleton robot with that of an exoskeleton walker in training the balance of stroke survivors in the subacute stage.Methods:Thirty persons with subacute stroke were divided at random into a fixed robot group (15 cases) and a walking robot group (15 cases). In addition to conventional rehabilitation treatment, the fixed robot group underwent daily 20-minute treadmill-based fixed exoskeleton robot training, 5 days a week for 2 weeks. The walking group was trained with an exoskeleton walking robot on the same schedule. Before and after the treatment, the Berg balance scale, the sitting modified functional stretch test (SMFRT), an isokinetic muscle strength test and the modified Barthel index (MBI) were used to evaluate the subjects′ global balance, self-dynamic balance, knee proprioception and ability in the activities of daily living (ADL).Results:After the treatment, both groups′ average Berg score, SMFRT extension difference, proprioceptive absolute error angle in the affected knee and MBI had improved significantly. The average SMFRT extension difference after treatment in the walker group was then significantly better than the fixed robot group′s average. However, the fixed robot group′s proprioception in the affected knee joint was then significantly better, on average, than among the walking robot group.Conclusions:Both fixed exoskeleton robot training and exoskeleton walker training can improve the balance, proprioception and ADL ability after a stroke. The former better improves dynamic balance; the latter better improves proprioception in the affected knee joint.

Objective:To explore the effect of anterior traction orthodontic treatment in adolescents with bone type Ⅲ malocclusion of different bone ages.Methods:Two hundred patients with bony class Ⅲ malocclusion admitted to the Department of Stomatology of the Zhangjiakou First Hospital were prospectively selected as the research subjects; An experienced physician divided the research subjects into the Cvs1 stage group ( n=54), the Cvs2 stage group ( n=56), the Cvs3 stage group ( n=47), and the Cvs4 stage group ( n=43) based on the morphological changes of the second, third, and fourth cervical vertebrae in the modified cervical spine analysis method. Before and after orthodontic treatment, X-ray lateral cranial films were taken respectively to compare the indicators of the upper airway and the structural indicators of the temporomandibular joint. Results:The nasopharyngeal volume (NPvolume), nasopharyngeal minimum cross-sectional area (NParea), and nasopharyngeal minimum cross-sectional sagittal diameter (NPsag) of the four groups of adolescents after treatment all increased significantly compared with those before treatment (all P<0.05), especially the increase was the most obvious in the Cvs3 stage group ( P<0.05). In the Cvs1 stage group, Cvs2 stage group, and Cvs3 stage group, except for the Y-axis to Mandibular first molar (Y-Mn6), Overbite, and the ratio of the Angle between the Posterior maxillary vertical to Occlusal plane angle (PMV/OP), there was no statistically significant difference before and after treatment (all P>0.05). The differences in other items before and after treatment were statistically significant (all P<0.05). Conclusions:Anterior traction orthodontic treatment has a significant effect on adolescents of different bone ages with skeletal class Ⅲ malocclusion, and can improve the maxillofacial structure and the position of the temporomandibular joint. There are differences in therapeutic effects among different bone age groups, and the effect of the Cvs3 stage group is the most obvious. These results provide important reference basis for clinical treatment decisions.

This study was aimed at exploring the epidemic characteristics and spatio-temporal evolution patterns of severe fever with thrombocytopenia syndrome(SFTS)in Henan Province from 2011 to 2022,to provide a reference for prevention and control ef-forts.Data on SFTS in Henan Province from 2011 to 2022 were collected from the Information Management System for Infectious Dis-ease Reporting,and epidemiological characteristics and spatio-temporal evolution patterns were investigated through spatial autocorre-lation analysis,standard deviation ellipse analysis,and spatial-centered transfer curves,on a district-county basis.From 2011 to 2022,a total of 5 471 SFTS cases associated with 81 deaths were reported in Henan Province.The incidence rate showed an increasing trend(χ2trend=23.24,P<0.001),and the average annual incidence was 0.4 677/100 000.The case-fatality rate showed a decreasing trend from 2011 to 2019(χ2trend=8.86,P=0.003),but an increasing trend from 2020 to 2022(χ2trend=12.93,P<0.001).The average an-nual case-fatality rate was 1.48%.The peak incidence period was from May to July;this period accounted for 58.75%of the total cases.Females(59.39%),individuals 60-80 years old(55.40%),and farmers(96.64%)were the high prevalence groups.The disease was distributed primarily in Xinyang City,and Shangcheng County had the highest incidence rate(27.411 8/100 000).Spatial aggregation was observed in the southeastern region(Moran's I>0,P<0.001),and the disease centers were all located in Guangshan County,Xin-yang City,and showed southeast-northwest-southeast-northwest-southeast-northeast-southwest movement during the 12-year pe-riod.In conclusion,from 2011 to 2022,SFTS in Henan Province had a high incidence in May to July,and females,older people,and farmers were the high-risk groups.Spatial aggregation was observed in the southeastern region,along with spread to surrounding areas.Xinyang City is therefore a key area for the prevention and control of SFTS.

With the deepening of the public hospital reform and the implementation of a series of policies,the external environment of the hospital has undergone profound changes,and the operation and management of the hospital has faced unprecedented pressure.Against this background,the case hospital has set up a special operation management team,established an operation evaluation index system that integrates business and finance,written an analysis report on"one policy for one department",set up an"operation management MDT clinic",and issued a list of operation problems to functional departments.A series of measures,such as the establishment of a set of operation management system with multi-line synergy,big data support,lean operation and evidence-based decision-making,have strongly guaranteed the scientific decision-making and efficient implementation of the hospital's operation management,and played a good role in the hospital's medical business,operation efficiency,cost structure,and management of the medical insurance fund,etc.The practical exploration of the operation management model has further improved the medical service level of the hospital and accelerated the pace of improving quality and increasing efficiency of the hospital.It is necessary to pay more attention to the refined management,continuously optimize the operation management system,and continuously promote the high-quality development of the hospital.
