ObjectiveTo investigate the effects of Huangqi Jianzhongtang （HQJZ） on macrophage polarization and fat consumption in cancer cachexia （CC） mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） was used to control the quality of HQJZ. （1） In vitro experiment： HQJZ-containing serum was prepared， and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages （RAW264.7） were cultured and randomly divided into six groups， including a blank group， a classically activated macrophages （M1） group， an alternatively activated macrophages （M2） group， a HQJZ + blank group， a HQJZ+M1 group， and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86， inducible nitric oxide synthase （iNOS）， CD206， and arginase-1 （Arg1） was detected by real-time quantitative polymerase chain reaction （Real-time PCR ）. （2） In vivo experiment： Thirty-two BALB/c mice were randomly divided into a control group， a model group， a medroxyprogesterone acetate （MPA） group， and a HQJZ group. Except for the control group， the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA （0.13 g·kg^-1·d^-1） or HQJZ （13.13 g·kg^-1·d^-1） by gavage， respectively， while mice in the control and model groups were given an equal volume of saline by gavage， with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers （iNOS， Arg1， CD86， CD206） and fat browning-related genes uncoupling protein 1 （UCP1） and peroxisome proliferator-activated receptor γ （PPARγ） in epididymal adipose tissue. Western blot （WB） was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography （micro-CT） was used to measure residual fat volume， and hematoxylin-eosin （HE） staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro， the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that， compared with the blank group， Arg1 expression decreased in the HQJZ+blank group （P<0.05）， CD206 showed a downward trend without statistical significance， while iNOS and CD86 expression were significantly increased （P<0.05）. Compared with the M1 group， Arg1 and CD206 expression decreased in the HQJZ+M1 group （P<0.05）. Compared with the M2 group， CD206 expression decreased in the HQJZ+M2 group （P<0.05）， CD86 expression increased significantly （P<0.01）. In vivo， Real-time PCR results showed that， compared with the control group， CD86 and CD206 expression levels were significantly increased in the model group （P<0.01）. Compared with the model group， CD206 expression in the MPA group was significantly decreased （P<0.01）. In the HQJZ group， CD206 was significantly decreased （P<0.01）. WB results showed that， compared with the model group， protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group （P<0.05， P<0.01）. micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group （P<0.05）. HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group （P<0.05）. ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization， thereby delaying fat consumption in CC mice.

Objective: To investigate the trend in disease burden of asthma attributable to tobacco in China from 1990 to 2021, so as to provide the basis for improving intervention measures of asthma. Methods: Data on asthma-related mortality and disability-adjusted life years (DALY) attributable to tobacco among adults aged ≥30 years in China from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Age-standardized mortality and age-standardized DALY rate were calculated using the GBD world standard population structure to analyze the tobacco-attributable asthma burden. The average annual percent change (AAPC) was employed to evaluate temporal trends in the age-standardized mortality and DALY rate from 1990 to 2021. Results: In China, the age-standardized mortality and age-standardized DALY rate of asthma attributable to tobacco decreased from 0.73/100 000 and 22.20/100 000 in 1990 to 0.17/100 000 and 6.64/100 000 in 2021, showing downward trends (AAPC=-4.603% and -3.888%, both P<0.05). Among males, the tobacco-attributable age-standardized mortality and age-standardized DALY rate declined from 1.44/100 000 and 41.05/100 000 in 1990 to 0.36/100 000 and 12.79/100 000 in 2021 (AAPC=-4.369% and -3.810%, both P<0.05). Among females, the corresponding rates decreased from 0.21/105 and 5.37/105 to 0.03/105 and 1.08/105 (AAPC=-6.074% and -5.074%, both P<0.05). In 2021, males had higher tobacco-attributable age-standardized mortality and age-standardized DALY rate for asthma than females. Both the mortality and DALY rate of asthma attributable to tobacco increased with age, peaking in the age group ≥80 years at 7.84/100 000 and 112.07/100 000, respectively. Conclusion From 1990 to 2021, the disease burden of asthma attributable to tobacco showed a declining trend in China, with males and elderly population aged ≥80 years bearing a relatively heavier disease burden.

AIM: To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC).METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024. Patients were divided into an observation group [undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation] and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL. Postoperative visual acuity(LogMAR), visual quality, and patient satisfaction were compared between the two groups.RESULTS: A total of 33 patients(47 eyes)were finally included in this study, including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group. The observation group had a median age of 59.0(52.8, 63.8)y, with 8 males(13 eyes)and 2 females(4 eyes). The control group had a median age of 56.0(53.5, 60.0)y, with 13 males(17 eyes)and 10 females(13 eyes). At 3 mo postoperatively, the best-corrected distance visual acuity(BCDVA)was 0.10(0.08, 0.12)in the observation group and 0.20(0.10, 0.40)in the control group(P=0.586). However, the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10, 0.10)vs 0.50(0.40, 0.90), P=0.032] and best-corrected near visual acuity(BCNVA)[0.20(0.18, 0.20)vs 0.60(0.45, 1.45), P=0.044] in the observation group were significantly better than those in the control group. The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of -2.00 to +1.00 D, which was superior to that in the control group. Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10% and 60%, respectively).CONCLUSION: Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity, reduces spectacle dependence, and maintains distance visual acuity by extending the depth of focus, providing better postoperative visual quality and life satisfaction for HMC patients.

This study focuses on the core pathology of sinew wei （痿）， which is mainly characterized by the fai-lure of qi and blood to nourish the sinews. A mechanical-biological response framework is constructed with mitochondria as a key component， explaining the modern interpretation of the disease location of sinew transmitting to qi and blood pathology. Mechanical loading， as a physical stress stimulus applied to the body， manifests primarily as passive loading formed by external forces such as massage， and active loading resulting from voluntary muscle contractions， such as dao yin （导引）. Mechanical loading can regulate mitochondrial function through two pathways， mechanical signal transduction and metabolic demand-driven regulation. Skeletal muscle mitochondrial dysfunction is regarded as the core microscopic basis of qi imbalance in sinew wei， highlighting the intrinsic connection between qi and mitochondrial energy metabolism， as well as between blood and microcirculatory efficiency. Accordingly， distinct regulatory patterns of mechanical loading are identified. Wei associated with qi stagnation may correspond to mitochondrial network fragmentation and can be treated by regulating qi through passive loading， such as tuina， to restore mitochondrial dynamics. In contrast， wei caused by qi deficiency is attributed to insufficient mitochondrial biogenesis and may be treated by tonifying qi through active loading， such as dao yin， to promote mitochondrial biogenesis. This framework reveals the biological differences in mitochondrial regulation induced by distinct mechanical loading modalities and provides a microscopic mechanism-based explanation for the principle of "treating the same disease with different methods" in sinew wei.

Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ²=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

BACKGROUND:Acupuncture is an effective method for lumbar pain in lumbar disc herniation,but its mechanism has not yet been clarified.Factors related to the JAK2/STAT3 signaling pathway regulate the body's inflammatory response and are involved in the process of neuropathic pain. OBJECTIVE:To study the mechanism of acupuncture on lumbar disc herniation in a rat model based on the JAK2/STAT3 signaling pathway. METHODS:Forty Sprague-Dawley rats were randomly divided into four groups:sham operation group,model group,acupuncture group,and acupuncture+agonist group,with 10 rats in each group.Animal models of L5 lumbar disc herniation was constructed through autologous disc cell transplantation in the model group,acupuncture group,and acupuncture+agonist group.Rats in the acupuncture group and the acupuncture+agonist group received acupuncture treatment(Yanglingquan,Shenshu,Huantiao,and Dachangshu acupoints)at 3 days after modeling,and acupuncture treatment was given once a day,20 minutes each,for 15 consecutive days.Rats in the acupuncture+agonist group were injected intrathecally with coumermycin A1,a JAK2 agonist,into the L4/L5 intervertebral space,once a day,20 minutes each,prior to the acupuncture at 6,12,and 18 days after modeling.Paw withdrawal mechanical threshold was detected before and 3,6,9,12,15,and 18 days after modeling.At 18 days after modeling,serum inflammatory factor levels were detected,hematoxylin-eosin staining was performed to observe the morphology of L5-L6 tissues,RT-PCR was performed to detect the expression of JAK2 and STAT3 mRNAs in L5-L6 tissues,and western blot was performed to detect the expression of JAK2,p-JAK2 and p-STAT3 proteins in L5-L6 tissues. RESULTS AND CONCLUSION:The paw withdrawal mechanical thresholds of rats in the model group at different time points after modeling were lower than those in the sham operation group(P<0.05),the paw withdrawal mechanical thresholds of rats in the acupuncture group were higher than those in the model group at 9,12,15,and 18 days after modeling(P<0.05),and the paw withdrawal mechanical thresholds of rats in the acupuncture+agonist group were lower than those in the acupuncture group at 9,12,15,and 18 days after modeling(P<0.05).The levels of interleukin 6,tumor necrosis factor α,neurotransmitter substance P,and brain neuropeptide Y were elevated in the model group compared with the sham operation group(P<0.05);the levels of all four inflammatory factors were reduced in the acupuncture group compared with the model group(P<0.05);and the levels of all four inflammatory factors were elevated in the acupuncture+agonist group compared with the acupuncture group(P<0.05).Hematoxylin-eosin staining showed that lumbar degeneration was obvious in the model group but reduced in the acupuncture group and the acupuncture+agonist group.Moreover,the reduction was more obvious in the acupuncture group compared with the acupuncture+agonist group.The JAK2 and STAT3 mRNA expression as well as the p-JAK2 and p-STAT3 protein expression were elevated in the model group compared with the sham operation group(P<0.05),were decreased in the acupuncture group compared with the model group(P<0.05),and were increased in the acupuncture+agonist group compared with the acupuncture group(P<0.05).To conclude,acupuncture can alleviate inflammation to exert analgesic effects in the rat model of lumbar disc herniation,and its mechanism of action may be related to the inhibition of the JAK2/STAT3 signaling pathway.

Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

Objective: To investigate the situation and influencing factors of school bullying experienced by primary and middle school students, so as to provide the basis for formulating school bullying intervention measures and promoting students' physical and mental health development. Methods: All the counties (cities, districts) in Zhejiang Province were stratified to urban and suburban areas, primary, junior high and senior high school students were selected using a stratified cluster sampling method. Basic information, lifestyle and school bullying were collected through questionnaire surveys. Factors affecting school bullying experienced by primary and middle school students were analyzed using a multivariable logistic regression model. Results: Totally 137 846 valid questionnaires were recovered, with an effective recovery rate of 97.17%. There were 72 526 males (52.61%) and 65 320 females (47.39%). There were 47 561 primary school students (34.50%), 47 701 junior high school students (34.61%) and 42 584 senior high school students (30.89%). A total of 3 987 students suffered from school bullying, accounting for 2.89%. The proportions of being maliciously teased, being intentionally excluded from group activities/isolated, being teased about physical defects or appearance, being hit/kicked/pushed/shoved/locked in a room, being threatened, and being extorted for money were 2.04%, 1.18%, 1.11%, 0.86%, 0.84% and 0.83%, respectively. Multivariable logistic regression analysis showed that the students who were males (OR=1.122, 95%CI: 1.048-1.202), lived in suburban areas (OR=1.322, 95%CI: 1.233-1.418), lived in areas with medium (OR=1.086, 95%CI: 1.006-1.173) or underdeveloped (OR=1.298, 95%CI: 1.191-1.415) economic level, had higher academic levels (junior high school, OR=1.380, 95%CI: 1.270-1.499; senior high school, OR=1.210, 95%CI: 1.083-1.351), lived on campus (OR=1.489, 95%CI: 1.372-1.616), engaged in fights (OR=6.029, 95%CI: 5.585-6.509), attempted to smoke (OR=1.320, 95%CI: 1.128-1.545), drank (OR=1.735, 95%CI: 1.575-1.912), were scolded and beaten by parents (OR=1.972, 95%CI: 1.822-2.135) and were obese (OR=1.240, 95%CI: 1.132-1.360) were more likely to experience school bullying. Conclusion The harm of school bullying to the physical and mental health of primary and middle school students should be taken seriously, and active policy measures should be adopted to strengthen intervention.

Objective: To understand the health status of primary school freshmen in Guiyang and the health management service needs of parents after examination, so as to provide a reference for establishment of a collaborative health management framework involving schools, families, and healthcare providers. Methods: From September to October 2024, a stratified random cluster sampling method was used in Guiyang City to select 3 210 students and 3 133 parents who participated in the physical examination for primary school freshmen. Demographic indicators, physical examination indicators and laboratory examination indicators of students were collected, and parents needs for post examination health management service were investigated by self designed questionnaire. Multiple linear regression analysis was adopted to investigate the related factors of parents health management service needs after the examination. Results: The detection rates of common illness among primary school freshmen were 60.22% for dental caries, 17.23 % for screening myopia, 6.11% for obesity, 3.86% for iron deficiency anemia, and 1.15% for scoliosis. The co-occurrence rate of common illness among freshmen during the physical examination was 23.89% ( n =767), among which the comorbidity rate of screening myopia and dental caries (8.22%) and obesity and dental caries (4.27%) were higher. About 63.80% parents indicated that the physical examination items were simple, and 2 366 parents (75.52%) indicated a demand for post examination management services; the average score of parents demands for post examination services was (3.12±0.70). In terms of the scores of each dimension, the mean score of nutrition and health (3.58±0.74) was the highest, while the lowest mean score was for traditional Chinese medicine health care (2.77±0.67). The mean scores for the other dimensions were as follows:exercise intervention (3.29± 0.79 ), psychological monitoring (3.17±0.58), and health education and signing (2.81±0.73). The results of multiple linear regression analysis showed that parents educational level (junior high school, high school/vocational school, college/undergraduate and above), living conditions (floating), and children s illness status (1, 2, >3 types) were the related factors of parents health management service needs after the entrance examination for new students ( B =2.16, 3.07, 3.68; -2.19; 3.14, 3.34, 3.11, P <0.05). Conclusions The prevalence of common illness in primary schools in Guiyang is characterized by a heavy burden from single diseases, with a notable occurrence of multiple comorbidities. After the physical examination, parents have obvious demand for follow up health management services. These health management services should integrate the concept of multi disease prevention according to the needs of parents.

Objective To investigate the relationship between primary pulmonary mucinous adenocarcinoma (PPMA) mass type and pneumonia type and their difference in malignant degree, and to analyze the role of clinical manifestations and CT features in the diagnosis of this disease. Methods The clinical data of PPMA patients admitted in the First Affiliated Hospital of Xiamen University from May 2011 to March 2022 were retrospectively analyzed. According to CT features, they were divided into a mass type group and a pneumonia type group. The clinical manifestations, CT features and the degree of malignancy between the two groups were analyzed and compared. Results A total of 57 PPMA patients were enrolled. There were 17 males and 40 females, with an average age of (53.82±10.65) years, and 28 (49%) patients had reversed hato-like sign. There were 42 patients in the mass type group and 15 patients in the pneumonia type group. PPMA often occurs in both lower lungs, with clinical manifestations mainly of coughing and expectorating white mucoid sputum. There were statistical differences between the two groups in the maximum diameter of tumor (P<0.001), boundary condition (P<0.001) and pleural indentation sign (P=0.019). There was no statistical difference between the two groups in Ki-67 index (P>0.05). Conclusion There is no statistical difference in the degree of malignancy between the two types of PPMA. Considering their clinical manifestations and differences in imaging features, it is supported that the pneumonia type is just a progression of the mass type. CT can present various manifestations, among which the reversed hato-like sign is expected to become an important imaging feature. Combined with a high proportion of solid components, pleural indentation sign, and vacuole sign, reversed hato-like sign can play a significant role in the diagnosis of PPMA.
