The Fragment of Dunhuang Ancient Tibetan Moxibustion Therapy contains rich content on fire moxibustion therapy of Tubo-period Tibetan medicine, characterized by distinctive clinical features of Tibetan acupuncture and strong regional attributes. This paper systematically reviews the relevant materials on moxibustion in the Fragment and summarizes the findings as follows: Tibetan fire moxibustion mainly uses mugwort as the material, and terms like "fine mugwort", "broad bean" and "sheep dung pellet" refer to the size of the moxa cone. The number of moxa cones used is predominantly odd numbers, usually ranging from 5 to 21. The main indications for fire moxibustion cover internal medicine, external medicine, gynecology, pediatrics, and various pain syndromes. The therapy advocates for treating acute conditions and heat syndromes with moxibustion. The manuscript also records detailed contraindications, including time-based and seasonal taboos. Moxibustion is applied to both local and distal acupoints, reflecting the therapeutic concept of treating both proximal and distal regions. Furthermore, it documents simple and practical acupoint localization methods such as surface anatomical markers, proportional bone measurement, finger measurement, and hand-span measurement. Compared with contemporaneous Chinese medical moxibustion techniques, the moxibustion methods recorded in this Fragment are rich in content and present unique Tibetan theoretical characteristics. It provides valuable data and evidence for the excavation, application, and further research of Tibetan acupuncture and moxibustion.

This paper introduces the academic characteristics of Professor ZHANG Ren in treatment with acupuncture for refractory eye diseases in modern times, guided by "homotherapy for heteropathy" (same therapy for different diseases sharing the same pathogenesis). The refractory eye diseases in modern times include a variety of conditions such as glaucoma, macular degeneration, diabetic retinopathy, high myopia and its complications, dry eye, cortical visual impairment and genetic eye diseases. The same therapy is used because these diseases share the similar location and pathogenesis. Professor ZHANG optimizes the methods of acupoint selection and provides the comprehensive prescriptions, "basic prescription, prescription based on disease differentiation, and supplementary prescription". A variety of acupuncture manipulation techniques are operated in clinical practice, such as compound needling methods, penetration needling, manipulations for promoting qi movement and conducting qi flow. "Early, regular and persistent" treatment is the common requirement with "the same acupoints, the same prescription and the same acupuncture method" as well as at "the same time". It is also proposed that the treatment should be provided flexibly according to the different symptoms, "identifying the differences within similarities".

Objective To explore the mechanism of electroacupuncture in improving lipid metabolism in polycystic ovary syndrome(PCOS)based on metabolomics combined with transcriptomics.Methods Eight-een SD rats were divided into the control group,the PCOS group and the electroacupuncture group,with 6 rats in each group.The PCOS group and the electroacupuncture group used intragastric letrozole to establish the PCOS model.After the model was established,the electroacupuncture group was intervened with electroacu-puncture,while the control group was only given sodium carboxymethyl cellulose by gavage.Observed the changes in body weight and estrous cycle of the three groups,detected the sex hormones,blood lipids,liver function,ovarian morphology,plasma metabolism and liver function indicators of the three groups.Metabolo-mics was used to analyze the differences in metabolites in plasma,the differences in gene expression in the liv-er were detected by RT-qPCR.Results Weight gain and estrous cycle disorder occurred in the PCOS group,and the ovarian morphology showed a thinning of the granulosa cell layer,with a significant reduction in the number of corpus luteum and mature follicles.Meanwhile,sex hormones were abnormal(total testosterone and androgen levels were increased,estradiol and progesterone levels were decreased),dyslipidemia occurred(TC,TG,LDL-C were increased,HDL-C level was decreased),and liver function was abnormal(AST,total protein,ALB,TBIL were increased).The electroacupuncture group significantly reduced weight.It improved the estrous cycle,and the granulosa cell layer of the ovary thickened,with a significant increasing in the num-ber of corpus luteum and mature follicles.Meanwhile,sex hormone levels were improved(androgen and total testosterone levels were decreased,estradiol level was increased),lipid balance(TC,TG,LDL-C levels were reduced,HDL-C level was increased)and liver function(AST,total protein,ALB,and TBIL levels were de-creased)was restored.Transcriptomics suggested that electroacupuncture down-regulated the expression of cytochrome P450(CYPs)family genes related to steroid hormones and lipid metabolism,and the results were confirmed by RT-qPCR.Combined omics analysis revealed that electroacupuncture might mainly exert its effect on improving lipid metabolism disorders in PCOS rats through the linoleic acid metabolic pathway.Con-clusion Electroacupuncture can regulate lipid metabolism in rats with PCOS.

ObjectiveTo understand the seropositivity of neutralizing antibodies (NAb) and low-level NAb against SARS-CoV-2 infection in the community residents, and to explore the impact of COVID-19 vaccination and SARS-CoV-2 infection on the levels of NAb in human serum. MethodsOn the ground of surveillance cohort for acute infectious diseases in community populations in Shanghai, a proportional stratified sampling method was used to enroll the subjects at a 20% proportion for each age group (0‒14, 15‒24, 25‒59, and ≥60 years old). Blood samples collection and serum SARS-CoV-2 NAb concentration testing were conducted from March to April 2023. Low-level NAb were defined as below the 25^th percentile of NAb. ResultsA total of 2 230 participants were included, the positive rate of NAb was 97.58%, and the proportion of low-level NAb was 25.02% (558/2 230). Multivariate logistic regression analysis indicated that age, infection history and vaccination status were correlated with low-level NAb (all P<0.05). Individuals aged 60 years and above had the highest risk of low-level NAb. There was a statistically significant interaction between booster vaccination and one single infection (aOR=0.38, 95%CI: 0.19‒0.77). Compared to individuals without vaccination, among individuals infected with SARS-CoV-2 once, both primary immunization (aOR=0.23, 95%CI: 0.16‒0.35) and booster immunization (aOR=0.12, 95%CI: 0.08‒0.17) significantly reduced the risk of low-level NAb; among individuals without infections, only booster immunization (aOR=0.28, 95%CI: 0.14‒0.52) showed a negative correlation with the risk of low-level NAb. ConclusionsThe population aged 60 and above had the highest risk of low-level NAb. Regardless of infection history, a booster immunization could reduce the risk of low-level NAb. It is recommended that eligible individuals , especially the elderly, should get vaccinated in a timely manner to exert the protective role of NAb.

OBJECTIVE To explore the value of tuberculosis infection T cell spot test(T-SPOT.TB)combined with cytokines interleukin-2(IL-2),interferon-γ(IFN-γ)in differential diagnosis of active tuberculosis(ATB)and non-ATB.METHODS A total of 186 patients with pulmonary tuberculosis(TB)who were treated in Hebei Provincial Chest Hospital from Feb.2021 to Mar.2024 were recruited as the research subjects and were divided in-to the ATB group with 92 cases and the non-ATB group with 94 cases according to the result of sputum culture for MTB,which was taken as the golden standard.The T-SPOT.TB was carried out for all of the subjects.The base-line data were collected from the two groups of patients.The hierarchical regression analysis was performed by setting the T-SPOT.TB,IL-2 and IFN-γ as the dependent variables,clinical symptoms of cough and fever as the independent variables.The impact of the clinical characteristics on T-SPOT.TB,IL-2 and IFN-γ was observed.The value of T-SPOT.TB combined with cytokines IL-2 and IFN-γ in differential diagnosis and ATB and non-ATB was evaluated by means of principal component analysis(PCA)and partial least squares discrimi-nant analysis(PLS-DA).The efficiencies of T-SPOT.TB,IL-2,IFN-γ and prediction model were examined by receiver operating characteristic(ROC)curves.RESULTS There were significant differences in cough,fever,IL-1β,IL-2,IL-6,IL-8 and IFN-γ between the two groups(P＜0.05).There were statistically positive correlations between the clinical symptoms of cough,fever and the T-SPOT.TB,IL-2 and IFN-γ(P＜0.05).The result of PCA model and PLS-DA model showed that there were less significant individual differences between the ATB pa-tients and the non-ATB patients,the two groups could be remarkably clustered and identified.The area under the curve(AUC)of the joint model was highest(0.913)(0.875 to 0.950)(P＜0.05),with the sensitivity 90.24％,the specificity 74.54％.CONCLUSION The T-SPOT.TB combined with IFN-γ and IL-2 shows high sensitivity and specificity in differential diagnosis of ATB and non-ATB and can be used as method for auxiliary diagnosis of ATB,and it has significant clinical value.

Bronchial asthma is a common chronic heterogeneous airway disease that is pathologically characterized by airway hyperresponsiveness and chronic inflammation.The pathogenesis of this disease is complex.Essentially,it is an airway inflammatory response driven by abnormal activation of the immune system.Its occurrence and development involve the participation of various immune cells and immune factors,including B lymphocytes,T lymphocytes,mast cells,macrophages and dendritic cells,as well as key cytokines such as interleukin(IL)-4,IL-5,IL-13,and interferon(IFN)-γ.And key cytokines such as interleukin(IL)-4,IL-5,IL-13 and interferon-γ.The complex interactions between these immune cells and mediators cause a series of pathological changes such as increased airway mucus secretion,smooth muscle contraction and airway remodeling,ultimately leading to the appearance of clinical symptoms,such as chest tightness,shortness of breath,wheezing and coughing.This article conducts systematically reviews current understanding of the immunological pathogenesis of bronchial asthma,thereby providing theoretical references for drug development and clinical diagnosis and treatment.

The intestine and liver are closely connected both physiologically and pathologically, forming a so-called gut-liver axis, with the gut microbiota serving as a pivotal link in their bidirectional communication. Gut microbiota dysbiosis and gut-liver axis disruption play a key role in the development and progression of colorectal cancer liver metastasis (CRLM), though the underlying mechanisms have not been clearly elucidated. Certain gut microbiota, such as Escherichia coli and Enterococcus spp., can breach the intestinal barrier and translocate to the liver, promoting the formation of pre-metastatic niche. Fusobacterium nucleatum and Enterococcus faecalis enhance tumor cell invasion/migration, while Parabacteroides spp. suppress anti-tumor immunity in the liver TME. Interventions like fecal microbiota transplantation, dietary modifications, and traditional Chinese medicine have shown potential in clinical and preclinical studies to improve patient outcomes by targeting the gut microbiota, but their long-term efficacy and safety require further investigation. Future research should focus on elucidating the effects of specific bacterial species, metabolites, viruses, and fungi on tumorigenesis. Exploring the potential of gut microbiota-based precision medicine and personalized therapies will improve risk stratification and enable more targeted interventions for CRLM patients.

The "integrated time-space" perspective of life in traditional Chinese medicine holds that structure and function respectively belong to the realms of space and time. The orderly integration of time and space not only supports the existence and development of life， but also serves as the foundation for biological evolution. Based on this standpoint， this paper proposes the spatiotemporal structural theory of visceral manifestation， characterized by the fusion of time and space， the integration of internal and external dimensions， and the absence of primary or secondary distinctions. Using the individual human body as the boundary， it delineates the man and nature spatiotemporal structure， based on the theory of the "correspondence between man and nature"， and the internal spatiotemporal structure of the living body. The man and nature spatiotemporal structure， with yin-yang and the five phases as its core， reveals the correspondence and connectivity between the external environment and the internal zang-fu organs within the spatiotemporal dimension. The internal temporal structure of the body refers to the collective physiological rhythms related to the zang-fu organs， while the spatial structure refers to the tangible forms， spatial positions， and connective structures of the zang-fu organs. The proposal of the spatiotemporal structural theory of visceral manifestation represents a rational reconstruction and practical exploration of the essential connotations of visceral manifestation， aiming to provide new perspectives for subsequent theoretical research and clinical applications.
