Objective:
To analyze the regulatory effect of Atractylodes macrocephala Koidz. extract on the immune function of mice, so as to provide a reference for the study of the mechanism of Atractylodes macrocephala Koidz. regulating immune function.
Methods:
Forty-eight SPF healthy male ICR mice were randomly divided into control group and low (0.5 g/kg), medium (2.0 g/kg), and high (4.0 g/kg) dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day. The delayed allergy test was performed for 28 consecutive days. Sixty SPF healthy male ICR mice were randomly divided into a control group, polyinosinic acid injection group (model group), and low, medium, and high dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day for 14 consecutive days. On days 13 and 14 of administration, the mice in the model group and each dose group were intraperitoneally injected with sterile polyinosinic acid solution to perform the immunosuppressive experiment induced by polyinosinic acid. The mouse ear pieces were weighed, and the thymus and spleen of the mice were weighed and stained with HE to calculate the pathological scores. Peripheral blood was collected for blood cell detection and T cell classification.
Results:
Mice in each group had normal feeding, activity, and growth status, and no abnormality was observed. In the delayed allergy test, compared with the control group, the degree and rate of ear swelling in the low, medium and high dose groups were higher, the white blood cell count in the medium dose group was higher, and the absolute values of lymphocytes in the low and medium dose groups were higher (all P<0.05). Compared with the control group, the pathological scores of the thymus and spleen in the model group were higher (both P<0.05). In the immunosuppressive experiments in mice induced by polyinosinic acid, compared with the model group, the pathological score of the thymus in the high dose group was lower (P<0.05), and the boundary between the thymus cortex and medulla was improved.
Conclusions
Atractylodes macrocephala Koidz. extract can increase the degree of ear swelling and peripheral blood white blood cell count in mice. High dose of Atractylodes macrocephala Koidz. extract can improve the thymus injury induced by polyinosinic acid, and has an immunomodulatory effect.

Objective:To characterize the epidemiology of respiratory syndrome across healthcare facilities of different types and tiers in Beijing City, to compare pathogen-testing modalities and their associations with adverse outcomes, and to identify key factors associated with progression to severe illness, thereby informing regional prevention, control, and clinical optimization.Methods:The multicenter observational cohort study was performed using outpatient and emergency department data from five sentinel hospitals in Beijing (Beijing Xiaotangshan Hospital, Beijing Chaoyang District Shuangqiao Hospital, Beijing Haidian Hospital, Beijing You′an Hospital, Capital Medical University (Beijing You′an Hospital), and Beijing Ditan Hospital, Capital Medical University (Beijing Ditan Hospital)) from October 1st, 2023 to April 9th, 2025. Dual-target (two-plex) and triple-target (three-plex) respiratory specimens were collected. Demographic characteristics, visit information, pathogen-testing modalities and results were collected, and the epidemiologic features of patients who progressed to severe illness between the influenza high-incidence season (December to May) and the non-influenza season (June to November) were compared. Categorical variables were analyzed using the chi-square test. Multivariable logistic regression was used to estimate associations between covariates and risk of progression to severe illness.Results:Among the 192 131 cases, patients visited at Beijing You′an Hospital were concentrated in the 16 to 44 year age group, accounting for 66.79%(32 532/48 708). Beijing Xiaotangshan Hospital had a broad age distribution, with older adults comprising up to 22.35% (885/3 960). Of the 47 349 respiratory specimens across the five hospitals, Beijing You′an Hospital had the highest positivity rate for dual-target testing (46.76%(1 585/3 390)), while Beijing Haidian Hospital conducted the largest number of this tests ( n=12 514). For triple-target testing, Beijing You′an Hospital again had the highest positivity rate (45.03%(2 835/6 296)), whereas Beijing Ditan Hospital tested the most specimens ( n=12 011; positivity rate was 29.73%(3 571/12 011)). The influenza season within the same period (November 2023 to January 2024) exhibited a bimodal pattern, with alternating circulation of influenza viruses and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Among 32 744 outpatients/emergency patients who progressed to severe illness, significant seasonal differences were observed by sex, age, comorbidity status, and infection type ( χ2=6.60, 189.24, 32.71 and 189.99, respectively; all P<0.05). After adjustment for sex, age group, comorbidities, and infection type, testing modality remained significantly associated with risk of progression (dual-target testing, odds ratio ( OR)=0.116, 95% confidence interval ( CI) 0.111 to 0.122, P<0.001); no testing, OR=0.063, 95% CI 0.060 to 0.065, P<0.001). Conclusions:The epidemiological pattern of respiratory pathogens undergo significant changes after October 2023, which is characterized by alternating waves of influenza viruses and SARS-CoV-2 with pronounced seasonality and diversity. Substantial inter-hospital differences are observed in testing modalities and positivity rates. Risk of progression to severe illness varies significantly by sex, age, comorbidity burden, and infection type, and is closely associated with the testing modality. These findings support strengthening multiplex pathogen testing and targeted surveillance of high-risk groups to improve early identification and precise control of febrile-respiratory syndromes.

Sepsis is an organ dysfunction caused by a dysregulated host response to infection,often characterized by immune dysfunction.This condition typically manifests as an excessive inflammatory response at early stages,followed by immunosuppression at later stages.Due to this immunosuppressive state,patients with sepsis are susceptible to new infections,termed secondary infections,even after the primary infection has been controlled or resolved.In recent years,secondary infections in sepsis have garnered increasing clinical attention due to their risks to exacerbate the disease course,prolong hospital stay,and increase mortality risk.The sepsis-induced immunosuppression is central to the development of secondary infections,especially at the later stage of sepsis.Specifically,T cell function becomes impaired,natural killer cell activity decreases,and macrophage phagocytic ability weakens,all contributing to diminished immune surveillance.Additionally,the immune evasion mechanisms employed by pathogens responsible for secondary infections further complicate treatment.This review aims to elucidate the mechanisms of immunosuppression and its clinical significance in sepsis-related secondary infections,providing a guidance for optimizing treatment strategies.

Objective To analyze the effect of hand transmitted vibration on fingertip thermotactile perception threshold (TPT) among grinding workers in a sports equipment manufacturing enterprise. Methods A total of 151 male grinding workers from a sports equipment manufacturing enterprise in Guangdong Province were enrolled in the vibration exposure group, and 51 male workers without hand-transmitted vibration exposure were enrolled in the control group, using the judgment sampling method. Basic health conditions of the workers were surveyed in both groups. The TPTs of the distal phalanges of the index and little fingers on both hands were tested using an HVLab thermal perception tester. Results The detection rates of finger numbness and tingling among workers in the vibration exposure group were higher than those in the control group (92.1% vs 7.8% and 59.6% vs 0.0%, respectively, both P<0.01). The detection rates of numbness or tingling of different fingers in the vibration exposure group descended in the following order: index finger, middle finger, ring finger, thumb and little finger. The hot threshold of the index finger and little finger increased (all P<0.01), while the cold threshold decreased (all P<0.01) in the vibration exposure group, compared with the control group. The results of generalized linear regression analysis showed that with the increase of the duration of hand-transmitted vibration, the hot threshold of the index finger and the little finger of both hands increased (all P<0.01), and the cold threshold decreased (all P<0.01). The hot thresholds of workers with numbness of both the index fingers and left little finger were higher than those of workers without numbness of the same finger (all P<0.05). The hot threshold of workers with tingling of the left index finger was higher than those without tingling (P<0.05). The cold thresholds of workers with tingling of the both index fingers and left little finger were lower than those without tingling of the same finger (all P<0.05). The hot threshold of the right little finger increased with age (P<0.01), while the cold thresholds of both little fingers decreased with age (all P<0.01). Conclusion Hand-transmitted vibration exposure increases fingertip hot threshold and decreases fingertip cold threshold of workers exposed to hand-transmitted vibration. Years of service in hand-transmitted vibration work, finger numbness or tingling, and age were influencing factors of TPT. Fingertip TPT examination can be used to assist in the early detection of vibration-induced nerve injury in workers exposed to hand-transmitted vibration.
