Objective:
To analyze the process of handling a pulmonary tuberculosis(TB) outbreak among senior high school students in a boarding school in Chongqing, as well as to investigate the underlying causes of the outbreak, so as to provide evidence to inform TB prevention and control strategies in school settings.
Methods:
From November 2023 to April 2024, an epidemiological investigation was conducted into the TB outbreak in a grade 12 class from a boarding high school. Suspected cases were screened using symptom screening, tuberculin skin test (TST), and chest X-ray examinations. Confirmed cases underwent individual epidemiological interviews and sputum culture; Cultured positive mycobacterial strains were subjected to whole genome sequencing after identification as Mycobacterium tuberculosis.
Results:
A total of 10 active pulmonary TB cases were identified, all from the same class, yielding a student attack rate of 16.67%. Three isolates were culture positive, as well as all strains were of L2 type,and the WGS analysis of the strains suggested a common transmission chain. Excluding the index case, four additional cases were detected through symptom driven health care visits. Notably, 70% of patients presented with "chest tightness and chest pain" symptoms, and 50% had "cough" symptoms,but none were detected during morning health checks or tracking of absences due to illness. A total of 326 contacts were identified and underwent three rounds of screening and one follow up examination. In the initial screening, 35 close contacts from the same class showed strong TST positivity, corresponding to a strong positivity rate of 55.56%, significantly higher than the 20.76% observed among casual contacts ( χ 2=29.80, P <0.01). Among the 35 strongly TST positivvity close contacts and five individuals with moderate TST positivity whose induration had increased by ≥10 mm over two years, none received timely preventive treatment initially; five of them were subsequently diagnosed with active TB within three months. Following this, 25 individuals initiated preventive therapy, resulting in a preventive treatment initiation rate of 62.50%. Among TST negative classmates who converted to strong positivity on repeat TST testing at three months, 75.00% started preventive treatment, but only 22.22% completed the full course.
Conclusion
Inadequate implementation of morning health checks and cause tracking for absenteeism due to illness, poorly standardized screening procedures, and delayed preventive treatment may have been key factors contributing to the spread of the outbreak.

Sarcopenia is a systemic skeletal muscle disease characterized by the gradual decline of muscle mass,strength,and function,and its occurrence and development are related to multiple factors,involving several signaling pathways. Among them,the phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway,as a key pathway regulating cellular growth,survival,and metabolism,plays an important role in the formation and development of sarcopenia. Its abnormal activation or deactivation may lead to an imbalance in muscle protein metabolism,resulting in muscle atrophy and reduction. Modern medicine is still in the exploratory stage of treatment for sarcopenia. Traditional Chinese medicine (TCM),with its multi-pathway and multi-target characteristics,has shown increasing advantages in the prevention and treatment of sarcopenia. In recent years,various monomers, extracts,and compound formulas of TCM have been proven to effectively prevent and treat sarcopenia by promoting muscle cell protein synthesis,reducing protein degradation,inhibiting cell apoptosis and inflammatory response,and improving mitochondrial function. This paper reviewed the improvement effects of TCM on sarcopenia based on the PI3K/Akt pathway and explored its specific action mechanisms, aiming to provide new insights for the treatment of sarcopenia with TCM.

Processed electroencephalogram (EEG) indices, such as the Bispectral Index, have markedly influenced anesthesia practice as they translate brain activity into simple numerical indices. Nevertheless, as the manufacturing algorithms are not disclosed, the underlying neurophysiology remains obscured. Additionally, these indices are often affected by electromyographic contamination, pharmacological variability, and patient-specific EEG heterogeneity. In contrast, an EEG spectrogram, or density spectral array, preserves the frequency- and time-resolved structures of cortical oscillations. This information is presented in a form that is both physiologically meaningful and clinically interpretable. In this review, we trace the evolution of anesthesia from an index-based to a spectrogram-guided approach, and summarize the clinical rationale for adopting the latter. Key applications of this approach include the use of frontal alpha power as a biomarker of cortical stability and postoperative brain health, the identification of nociceptive arousal through alpha dropout and beta or delta arousal patterns, and individualized titration of multimodal or age-specific anesthetic management. Although current devices lack standardized quantitative alpha metrics and have limited sensitivity for low-frequency brain wave components, structured EEG education programs have proven to be effective in terms of fostering spectrogram literacy among anesthesiologists. By combining neurophysiological precision with bedside practicality, the EEG spectrogram represents a pivotal advance toward individualized, mechanism-based, and brain-protective anesthesia, transforming anesthetic monitoring from mere algorithmic abstraction to cortical insight.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Purpose:
Plasmablastic lymphoma (PBL) is a rare, aggressive lymphoma that is characterized by terminal B-cell differ‑ entiation. In the West, PBL usually occurs in patients with immunodeficiencies, particularly those induced by human immunodeficiency virus (HIV) infection. We investigated the clinicopathological features of PBL at a single institute in Taiwan, where HIV infection is rare.
Methods:
This retrospective chart review identified PBL cases that were treated at a single institute in southern Tai‑ wan between 2008 and 2024.
Results:
We identified nine patients (four males and five females; median age 71 years). Of the eight patients tested for HIV, only one tested positive. Pathologically, the tumors showed plasmablastic morphology and immunopheno‑ type, and three (33%) cases tested positive for Epstein–Barr virus. Six (67%) patients presented with Stage IV disease, including five (56%) with malignant effusion. Six patients were treated with chemotherapy and the remaining three received only supportive care. During a median follow-up of 10 months, five patients died of progressive disease, two died of unrelated diseases, and two were alive with PBL relapse.
Conclusion
In Taiwan, PBL constitutes a rare and aggressive clinical condition and is frequently associated with malignant effusion. In contrast to Western patients, the PBL in most patients from Taiwan was unrelated to HIV infection.

Objective:To investigate the clinical characteristics and major allergens of patients with pollen-food allergy syndrome(PFAS) and their correlation with the severity of symptoms, and to provide a basis for identifying high-risk patients, optimizing the allergen testing process and developing individualized dietary management strategies. Methods:The clinical data of 166 patients with PFAS admitted to our hospital from January 2021 to July 2023 were retrospectively analyzed. The clinical symptoms, pollen types and food allergy of the patients were analyzed by questionnaire survey and serum specific IgE detection. phi coefficient, Apriori algorithm modeling and multivariate logistic regression analysis were used to evaluate the association between allergen and symptom severity. Results:Artemisia pollen was the most common allergen in this area, with a positive rate of 96.39%. Peach and mango were the most common food allergens, which caused allergic reactions in 24.10% and 22.89% of patients, respectively. Oral mucosal symptoms were the main symptoms. Correlation analysis showed that there was a correlation between pollen allergens and allergenic food. Association rule analysis showed that when the patient was allergic to the combination of peanuts and trees, the probability of high severity of symptoms was 82.35%. Multivariate analysis showed that ragweed allergy was significantly positively correlated with the severity of PFAS symptoms. Conclusion:Artemisia pollen and related food allergens play an important role in the pathogenesis of PFAS. Association rule mining and network map analysis revealed direct associations between peanut and tree combination allergy and symptom severity, as well as potential links between other inhaled allergens and specific food allergies. Ragweed and peach allergy are independent risk factors for the aggravation of PFAS symptoms, which can be used as early warning indicators. These results help to improve the screening of high-risk patients and the construction of regional allergen databases.

The pathogenesis of pulmonary fibrosis (PF) is complex. It is characterized by myofibroblast hyperplasia and deposition of collagen protein. Indoleamine 2,3-dioxygenase 1 (IDO1) is expressed in lung fibroblasts and epithelial cells, but its functions in lung homeostasis and diseases remain elusive. Here, we characterize the critical role of IDO1 in PF patients and bleomycin (BLM)-induced PF mouse models. We find that IDO1 is significantly upregulated in the fibrotic lungs of patients and mice, showing a positive correlation with genes characteristic of fibrosis. Functionally, IDO1 knockout inhibits lung fibroblast proliferation, differentiation, mitochondrial biogenesis, and mitochondrial oxidative phosphorylation. Conversely, IDO1 overexpression and accumulation of kynurenine (Kyn) exacerbate progressive lung fibrosis. Mechanistically, IDO1-deletion activated profound mitochondrial fusion-enhanced potentially the capacity for fatty acid oxidation, along with activation of de novo glycolytic serine/glycine synthesis pathways and mitochondrial one-carbon metabolism. Wedelolactone (WEL), a small molecule IKK inhibitor, is found to strongly bind to IDO1 and effectively protect mice from PF in an IDO1-dependent manner. Collectively, this study characterizes a promotor role for IDO1 in PF and suggests a potential avenue of targeting IDO1 to treat lung diseases.

OBJECTIVE:
Acupuncture therapies are known for their effectiveness in treating a variety of gastric diseases, although the mechanisms underlying these effects are not fully understood. This study tested the effectiveness of electroacupuncture (EA) at acupoints Zhongwan (RN12) and Weishu (BL21) for managing gastric motility disorder (GMD) and investigated the underlying mechanisms involved.
METHODS:
A GMD model was used to evaluate the impact of EA on various aspects of gastric function including the amplitude of gastric motility, electrogastrogram, food intake, and the rate of gastric emptying. Immunofluorescence techniques were used to explore the activation of spinal neurons by EA, specifically examining the presence of cholera toxin B subunit (CTB)-positive neurons and fibers emanating from acupoints RN12 and BL21. The stimulation of γ-aminobutyric acid (GABA)-ergic neurons in the spinal dorsal horn, the inhibition of sympathetic preganglionic neurons in the spinal lateral horn, and their collective effects on the activity of sympathetic nerves were examined.
RESULTS:
EA at RN12 and BL21 significantly improved gastric motility compromised by GMD. Notably, EA activated spinal neurons, with CTB-positive neurons and fibers from RN12 and BL21 being detectable in both the dorsal root ganglia and the spinal dorsal horn. Further analysis revealed that EA at these acupoints not only stimulated GABAergic neurons in the spinal dorsal horn but also suppressed sympathetic preganglionic neurons in the spinal lateral horn, effectively reducing excessive activity of sympathetic nerves triggered by GMD.
CONCLUSION
EA treatment at RN12 and BL21 effectively enhances gastric motility in a GMD model. The therapeutic efficacy of this approach is attributed to the activation of spinal neurons and the modulation of the spinal GABAergic-sympathetic pathway, providing a neurobiological foundation for the role of acupuncture in treating gastric disorders.

OBJECTIVE:
This study examines the sequential mediating roles of body pain and self-reported health in the association between sleep duration and self-reported life satisfaction among elderly Chinese adults.
METHODS:
Data from the fifth wave of the China Health and Retirement Longitudinal Survey (CHARLS) were used to analyse the relationships between sleep duration and body pain, self-reported health, and life satisfaction through logistic regression and Restricted Cubic Spline (RCS) analyses. The sequential mediation effects of body pain and self-reported health status were examined via chain mediation analysis.
RESULTS:
Logistic regression analysis showed that sleeping fewer than 6 hours or 6-7 hours was linked to higher risks of body pain, poor health, and dissatisfaction with life compared to sleeping 7-8 hours (all P < 0.05). Additionally, those sleeping more than 9 hours also had increased risks of poor health and dissatisfaction with life compared to those sleeping 7-8 hours (all P < 0.05). Chain mediation analysis showed that body pain and self-reported health status sequentially mediated 46.15% of the association between sleep duration and life satisfaction.
CONCLUSION
Body pain and self-reported health may shape the relationship between sleep duration and life satisfaction in elderly Chinese adults.
