ObjectiveTo observe the clinical efficacy and safety of lung-boosting moxibustion with different moxibustion doses in the treatment of stable chronic obstructive pulmonary disease (COPD). MethodsA total of 240 stable COPD patients with lung qi deficiency, lung-spleen qi deficiency, or lung-kidney qi deficiency syndrome were enrolled, all receiving standardized western medical treatment and lung-boosting moxibustion. According to the thickness of the moxa wool, the thickness of the ginger paste, and the treatment duration, patients were randomly divided into eight groups, which were Group A (3.0 cm thickness moxa, 2.5 cm ginger mud, 60 min treatment time), Group B (3.0 cm thickness moxa, 2.5 cm ginger mud, 90 min treatment time), Group C (2.0 cm thickness moxa, 2.5 cm ginger mud, 60 min treatment time), Group D (2.0 cm thickness moxa, 2.5 cm ginger mud, 90 min treatment time), Group E (3.0 cm thickness moxa, 2.0 cm ginger mud, 60 min treatment time), Group F (3.0 cm thickness moxa, 2.0 cm ginger mud, 90 min treatment time), Group G (2.0 cm thickness moxa, 2.0 cm ginger mud, 60 min treatment time), Group H (2.0cm thickness moxa, 2.0cm ginger mud, 90 min treatment time). Treatment was performed once every 15 days for 3 months, with a total of six sessions. The primary outcomes were the scores of the clinical symptoms and signs questionnaire for stable COPD before and after treatment, comprising seven symptom domains (cough, sputum production, wheezing, chest tightness, shortness of breath, fatigue, and cyanosis) and the total score. The secondary outcomes included the scores of the modified COPD patient-reported outcome questionnaire (mCOPD-PRO) involving the physical, psychological, and environmental domains and the total score, the scores of the modified Effectiveness Satisfaction Questionnaire for COPD (mESQ-COPD) involving clinical symptoms, work and daily living capacity, environmental adaptability, treatment efficacy, and the total score before and after treatment, the moxibustion sensation scores (heat sensation score and special sensation intensity score) during treatment, and cutaneous temperature (the maximum temperature achieved, the duration of temperature maintained at ≥43 ℃, and the time required to reach 43 ℃). The safety evaluation was carried out after treatment. ResultsDuring the study, 18 patients withdrew, and 222 patients were included in the per-protocol set for analysis, including 27 in Group A, 28 in Group B, 28 in Group C, 29 in Group D, 27 in Group E, 28 in Group F, 27 in Group G, and 28 in Group H. After treatment, the total score on the clinical symptoms and signs questionnaire, as well as the cough and chest tightness symptom scores in Group F were significantly lower than those in other groups (P<0.05). Group F demonstrated statistically lower total mCOPD-PRO score and physical domain score (P<0.05), lower total mESQ-COPD score and the scores for clinical symptoms and treatment efficacy (P < 0.05), as well as higher heat sensation score (P<0.05) than other groups. The maximum temperature was significantly higher in Group E and Group F than in the other groups, while the duration of temperature maintained at ≥43 ℃ was significantly longer in Group F than other groups, and the time required to reach 43 ℃ was significantly shorter in Group E and Group F than in Groups C, D, G, and H (P<0.05). No significant abnormalities were observed in routine blood tests, liver function, renal function, urinalysis, or electrocardiograms before and after treatment in any group. No serious adverse events occurred during the treatment period. ConclusionThere are differences in the efficacy of different moxibustion doses of lung-boosting moxibustion in the treatment of stable COPD. Moxibustion with 3.0 cm thickness moxa, 2.0 cm ginger mud, and 90 min treatment time can obtain relatively superior efficacy while demonstrating a favorable safety profile.

ObjectiveTo explore the possible mechanism of action of Lifei Xiaoji Pill (理肺消积丸, LXP) in the treatment of non small cell lung cancer based on the Warburg effect and the USP47/BACH1 pathway. MethodsFifty C57BL/6 mice were randomly divided into five groups, model group, LXP group, inhibitor group, LXP + inhibitor group, and cisplatin group, with 10 mice in each group. A lung cancer mouse model was established by subcutaneously injecting Lewis cells. On the next day, the model group mice were given 0.2 ml of saline by gavage daily, the LXP group given 240 mg/(kg·d) of LXP solution once a day by gavage, the inhibitor group intraperitoneally injected with P22077 at a dose of 10 mg/(kg·d) every day, the LXP + inhibitor group given both LXP by gavage and P22077 by intraperitoneal injection once a day, and the cisplatin group received 0.5 mg/(kg·d) cisplatin intraperitoneally every other day. All treatments lasted for 14 days. On the day after the last dose, tumor weight and volume were measured, tumor histopathology was examined by HE staining, apoptosis in tumor tissues was detected by TUNEL staining, and proliferation cell nuclear antigen (PCNA) protein levels were detected by immunohistochemistry. Warburg effect indicators, including glucose concentration, lactate content, and adenosine triphosphate (ATP) production in tumor tissues, were measured. Western Blot and qRT-PCR were used to detect the protein and mRNA expression levels of USP47, BACH1, hexokinase 2 (HK2), and glyceraldehyde 3-phosphate dehydrogenase (GAPDH). ResultsCompared with the model group, all drug intervention groups showed reduced tumor weight and volume, improved tumor pathology, decreased PCNA positive rate, increased apoptosis rate, and reduced expression levels of USP47, BACH1, and HK2 proteins and mRNA (P<0.05 or P<0.01). Except for lactate content in the cisplatin group, the glucose concentration in tumor tissues of other drug intervention groups increased, while lactate content and ATP production decreased (P<0.05 or P<0.01). Compared with the LXP group, the LXP + inhibitor group showed more significant improvements in these indicators (P<0.05 or P<0.01). Compared with the cisplatin group, the LXP + inhibitor group had lower mRNA expression of HK2 and GAPDH, and lower protein levels of USP47 and HK2 (P<0.05 or P<0.01). Compared with the inhibitor group, the cisplatin group had higher HK2 protein levels, while the LXP + inhibitor group showed lower mRNA expression of BACH1, HK2, and GAPDH (P<0.05 or P<0.01). ConclusionLXP significantly inhibits tumor growth in lung cancer mice, and its mechanism of action may be related to inhibiting the Warburg effect via the USP47/BACH1 pathway.

International Journal of Traditional Chinese Medicine 2025;47(2):286-288,F4
Yuebi Jia Banxia Decoction comes from Jin Gui Yao Lue. Its medicinal taste is simple and suitable for the syndrome of internal heat retention and wind pathological factors. Modern clinical practice often uses its modified prescription combined with Western medicine therapy to treat respiratory diseases such as bronchial asthma, COPD, pneumonia, bronchitis, and pulmonary heart disease, which can improve symptoms and signs such as asthma, cough, and phlegm, reduce airway hyperresponsiveness, inhibit chronic inflammation, and improve lung function. It can also effectively reduce recurrence and has good safety. The mechanism may be related to regulating cytokine levels, alleviating airway inflammation, improving immune function, regulating various amino acid metabolism levels, down-regulating ERK and NF-κB expressions, and increasing serum fibronectin levels. There were few experimental studies on this mechanism, which need to be strengthened in the future.

OBJECTIVES:
To explore the mechanism that mediate the therapeutic effect of quercetin on heart failure.
METHODS:
We searched the TCMSP and Swiss ADME databases for the therapeutic targets of quercetin and retrieved heart failure targets from the Genecards and OMIM databases. The intersecting targets were analyzed with GO and KEGG pathway analysis using DAVID database, and the key genes were identified via PPI analysis. Molecular docking between the core targets and quercetin was performed using PyMOL and AutoDock Tools. In a heart failure model established in H9C2 cardiomyocytes by treatment with isoproterenol, the effect of quercetin on the expressions of the MAPK signaling pathway was tested.
RESULTS:
A total of 60 intersecting targets were identified. Enrichment analysis revealed that quercetin may inhibit heart failure through the MAPK signaling pathway. The core genes, including AMPK3 and BCL-2, were identified as potential key regulators in quercetin-mediated improvement of heart failure. Cellular experiments demonstrated that quercetin significantly reduced isoproterenol-induced apoptosis of cardiomyocytes in a dose-dependent manner and obviously decreased the Bax/Bcl-2 ratio and the expression levels of caspase-3, ERK and p38 in the cells.
CONCLUSIONS
Quercetin improves heart failure possibly by inhibiting cardiomyocyte apoptosis through the MAPK signaling pathway.

OBJECTIVES:
To evaluate the protective effect of Bufei Yishen Formula (BYF) against cigarette smoke extract (CSE)-induced injuries in human bronchial epithelial BEAS-2B cells and explore the underlying mechanism.
METHODS:
BEAS-2B cells exposed to CSE were treated with normal rat serum, BYF-medicated rat serum at low or high doses, pyrrolidine dithiocarbamate (PDTC, a NF-κB inhibitor), PDTC combined with high-dose BYF-medicated serum, or S-carbomethyloysteine (S-CMC, as the positive control). CCK-8 assay was used to determine the optimal concentration and treatment time of CSE, BYF-medicated serum and S-CMC. The treated cells were examined for inflammatory factor levels in the supernatant and cellular expressions of MUC5AC and MUC5B using ELISA, cell ultrastructural changes with transmission electron microscopy, and cell apoptosis rate using flow cytometry. The expression levels of TLR4/NF‑κB pathway-associated mRNAs and proteins were determined by qRT-PCR and Western blotting.
RESULTS:
CSE exposure significantly increased secretions of IL-1β, IL-6 and TNF-α, mRNA and protein expressions of MUC5AC and MUC5B, and early and total apoptosis rates in BEAS-2B cells, where the presence of apoptotic bodies was detected. CSE also significantly enhanced the mRNA and protein expressions of TLR4, I-κB, and NF-κB and reduced mRNA and protein expressions of AQP5. Treatments of the CSE-exposed cells with BYF-medicated serum, PDTC and S-CMC all significantly lowered inflammatory factor levels, MUC5AC and MUC5B expressions, and early and total cell apoptosis rates, and partly reversed the changes in cellular ultrastructure and mRNA and protein expressions of the TLR4/NF-κB pathway, and the effects were the most conspicuous following the combined treatment with high-dose BYF-medicated serum and PDTC.
CONCLUSIONS
BYF can inhibit cell apoptosis, inflammation and mucus hypersecretion in CSE-induced BEAS-2B cells by inhibiting the TLR4/NF-κB signaling pathway.

Chronic obstructive pulmonary disease (COPD) is a common clinical chronic airway disease with high morbidity, high mortality, a heavy disease burden, and complex mechanisms that have not been fully elucidated. Clinical problems promote the continuous progress of basic research. The establishment and evaluation of animal models is an important way to delve into the pathogenesis and treatment strategies of COPD. On the basis of the etiology, pathogenesis, diagnostic criteria, and syndrome differentiation of COPD in traditional Chinese medicine (TCM) and Western medicine, this paper summarizes the establishment methods and characteristics of existing animal models of COPD and analyzes the fitting degree of the models with the disease characteristics in Western medicine and syndrome characteristics in TCM. The results showed that the animal models of COPD in Western medicine were mainly induced by single factors and compound factors, and the model with the highest fitting degree was established by cigarette smoke combined with lipopolysaccharide and hormone. The model showed a fitting degree of 84% with the disease characteristics in Western medicine and 70% with the syndrome characteristics in TCM, being consistent with the clinical characteristics of COPD induced by multiple factors. Most of the animal models of COPD in TCM were established on the basis of disease models and combined with TCM etiology and pathogenesis characteristics, and prepared by syndrome differentiation. Among them, the model of accumulation of cold and water retention in lung had the highest fitting degree of 92% with the TCM diagnostic criteria. The models of phlegm-heat obstructing lung and phlegm-stasis obstructing lung had the fitting degree of 94% with clinical manifestations in Western medicine and the highest fitting degree with the diagnostic criteria in Western medicine. Different animal models of COPD have their own advantages and disadvantages, and most of them simply replicate the manifestations of COPD at a certain stage, failing to reflect the multiple causes and the dynamic changes of TCM etiology and pathogenesis. Moreover, the syndromes of these models fail to match the clinical syndromes in TCM. Therefore, establishing the animal models reflecting clinical characteristics of COPD in TCM and Western medicine and improving the model evaluation criteria are important contents to promote the overall development of integrated traditional Chinese and western medicine for COPD.

The rules of acupoint selection and treatment were identified and discovered from the collected ancient acupuncture-moxibustion prescriptions recorded the earliest for epigastric pain. The database of ancient acupuncture-moxibustion prescriptions for epigastric pain was set up using Excel2016 software. After the disease term, etiology, pathogenesis, symptoms and acupoints were normalized, the underlying multi-dimensional correlation among the elements of acupuncture-moxibustion was explored, using the frequency statistics and the association rule of Apriori algorithm. In the ancient time, in treatment with acupuncture-moxibustion therapy for epigastric pain, the acupoints of the high use frequency were sequenced as Zhongwan (CV12), Shangwan (CV13), Zusanli (ST36), Neiguan (PC6), Gongsun (SP4), Pishu (BL20) and Weishu (BL21). The common combinations of acupoints included the pairs of back-shu points, the combination of back-shu points and front-mu points, the combination of front-mu points and yuan-source points and the combination of back-shu points and the lower he-sea points. The highly involved acupoints were those from the conception vessel, pericardium meridian, spleen meridian, stomach meridian and bladder meridian; and they were commonly distributed on the abdomen, the yin parts of the foot and the arm, the yang part of the leg and on the back. Regarding the etiologies such as parasites, food retention, masses, qi stagnation and stomach cold, Zhongwan (CV12) and Shangwan (CV13) were coordinated; and Sanyinjiao (SP6) and Daling (PC7) were highly associated with masses. Besides cold injury, parasites and masses, for the epigastric pain caused by other factors of etiology (qi stagnation, stomach cold and food retention), moxibustion therapy was greatly applicable. For epigastric pain combined with qi reversion in the lower abdominal region, Qichong (ST30), Sanyinjiao (SP6), Tianshu (ST25) and Zusanli (ST36) must be selected. Dadu (SP2) and Taibai (SP3) must be used if the distention in the chest and abdomen accompanied; and Zhongzhu (TE3) be used if back pain involved. Zusanli (ST36) was commonly selected for hiccups. For the other accompanied symptoms, Zhongwan (CV12) was used, which is consistent with the acupoint selection of main symptoms. On the trunk, moxibustion was generally used at Weishu (BL21), Pishu (BL20), Geshu (BL17), Zhongwan (CV12), Juque (CV14) and Qihai (CV6), except Shangwan (CV13). Among the acupoints below the elbows and knees, moxibustion was commonly applicable at Zusanli (ST36), and acupuncture was often used at Gongsun (SP4) and Daling (PC7).

AIM:This study aimed to explore the mechanism by which Bufei-Yishen formula(BYF)mitigates mitochondrial damage in rats with chronic obstructive pulmonary disease(COPD)by regulating the AMPK/PGC-1α signal-ing pathway.METHODS:Forty rats were randomly divided into four groups,each containing ten rats each:control group,COPD group,BYF group,and N-acetylcysteine(NAC)group.The COPD model was established through chronic cigarette smoke exposure combined with periodic bacterial inoculations over an eight-week induction phase.During the subsequent eight-week treatment period(i.e.,weeks 9~16),rats in the control and COPD groups received an isovolumet-ric saline solution via oral gavage,at a standardized daily dose of 2 mL per animal.Moreover,rats in the BYF and NAC groups were given Bufei Yishen formula(11.61 g·kg-1·d-1)or N-acetylcysteine(54 mg·kg-1·d-1)by gavage,once per day.At week 16,samples were collected and the general condition of the rats was observed.Body weight was recorded weekly.We also obtained data characterizing rat lung function,lung pathology,ATP content,and mitochondrial ultra-structure,as well as the levels of interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α),interleukin-1β(IL-1β),se-rum transforming growth factor-beta 1(TGF-β1)and the enzymatic activities of mitochondrial electron transport chain complexes I(NADH dehydrogenase)and III(cytochrome c reductase).Finally,we quantified the mRNA and protein lev-els of AMPK and PGC-1α in lung tissue.RESULTS:Compared to the control group,the COPD group exhibited yellow-ish hair color,reduced gloss,slower weight gain,and a disordered respiratory rhythm.We also observed significant de-creases(P<0.01)in pulmonary function tidal volume(TV),minute ventilation(MV),peak expiratory flow(PEF),expi-ratory flow at 50%of tidal volume(EF50),forced vital capacity(FVC),forced expiratory volume in 0.1 s(FEV0.1),and FEV0.1/FVC.Histopathological analysis showed alveolar cavity enlargement,bullous changes in lung morphology,smooth muscle hypertrophy in the tracheal wall,ciliary destroyed,mucosal shrinking and thickening,and a large number of in-flammatory cells gathered around the tube.Moreover,the mean linear intercept(MLI)and bronchial wall thickness(BWt)had both significantly increased(P<0.01).Electron microscopic analysis of the lungs revealed a reduction in the number of mitochondria in alveolar epithelial cells,a swollen and deformed lung morphology overall.We observed that the mitochondrial cristae were broken,dissolved or vacuolated,accompanied by a significant reduction in the number of lamel-lar bodies and lung volume,along with a disordered internal lipid layer structure.Furthermore,some lung samples were vacuolated or had content leakage.Further quantitative analyses showed statistically significant increases(P<0.01)in the levels of serum pro-inflammatory mediators,including IL-6,TNF-α,IL-1β,and TGF-β1.At the same time we observed substantial reductions in the enzymatic activities of mitochondrial electron transport chain complexes I and III(P<0.01).Moreover,we found that metabolic impairment correlated with significantly attenuated ATP production(P<0.01)in exper-imental subjects.Moreover,the expression levels of AMPK and PGC-1α mRNA and proteins in lung tissue were signifi-cantly decreased(P<0.01).Moreover,compared to the COPD group,the BYF group showed significant improvements in several of the above indicators,albeit to different degrees(P<0.01 or P<0.05).Moreover,BYF was more effective than NAC in improving minute ventilation and up-regulating PGC-1α expression(P<0.05).CONCLUSION:Bufei-Yishen formula may ameliorate mitochondrial damage in rats with chronic obstructive pulmonary disease by regulating the AMPK/PGC-1α signaling pathway.

Objective:To analyze the correlation between near work, screen time, outdoor time and myopia in children based on objective monitoring technology and to explore the influencing factors related to myopia in children.Methods:A cross-sectional study was conducted.From October 2022 to March 2023, the purposive sampling method was used to select 596 children in Grade 2 and Grade 3 from two primary schools in Shandong Province as study subjects.Eye-Monitor technology of eye-use behavior based on artificial intelligence was used to quantify parameters of near work, screen time and outdoor time.The eye-use behavior parameters were compared within each subject and between non-myopic and myopic children on weekdays and weekends.A multivariate binary logistic regression model was constructed to analyze the influencing factors related to myopia.The study protocol was approved by the Medical Ethics Committee of the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine (No.HEC-HY-2022023KY).Written informed consent was obtained from the legal guardian of each subject.Results:For each subject, the proportion of near work time on weekdays was greater than on weekends, the proportion of time spent looking at cell phones, computer screens, and outdoor activities was smaller, the duration of single continuous near eye use was longer, the tilt angle of the head in sitting position was greater, and the light intensity was stronger, showing statistically significant differences ( t=19.427, -9.964, -5.916, -10.470, 2.211, 2.898, 15.061; all P<0.05).During weekdays, compared with the non-myopia group, the myopia group had longer total near work duration, longer single continuous near eye use duration, shorter outdoor activity duration, closer eye use distance, larger proportion of near work time, and smaller proportion of outdoor activity time, showing statistically significant differences (all P<0.05).During weekends, compared with the non-myopia group, the myopia group had longer time spent looking at cell phones and computer screens, shorter outdoor activity time, greater proportion of time spent looking at cell phones and computer screens, and smaller proportion of outdoor activity time, with statistically significant differences (all P<0.05).During weekdays, after adjusting for confounding factors, longer single continuous near eye use duration ( OR=1.138, 95% CI: 1.086-1.192, P<0.001) was the risk factor for myopia, and longer working distance ( OR=0.906, 95% CI: 0.847-0.970, P=0.004) and longer outdoor activity time ( OR=0.127, 95% CI: 0.023-0.703, P=0.018) were protective factors for myopia.During weekends, after adjusting for confounding factors, longer time spent on looking at cell phone screens ( OR=2.437, 95% CI: 1.460-4.068, P<0.001) and longer time spent on looking at computer screens ( OR=2.260, 95% CI: 1.283-3.979, P=0.005) were risk factors for myopia, and longer outdoor activity time ( OR=0.624, 95% CI: 0.416-0.934, P=0.022) was the protective factor for myopia. Conclusions:The eyes with continuous near work, prolonged use of smartphone and computer screens, closer eye use distance, and less time spent outdoors have been confirmed to be significantly correlated with myopia based on objective monitoring data.When formulating intervention measures for myopia prevention and control in children, it is advocated to further pay attention to control the distance and duration of near work on weekdays and strengthen screen time management on weekends.
