Chronic obstructive pulmonary disease （COPD） is a chronic respiratory disease that poses a significant threat to global health， exhibiting high morbidity， disability and mortality rate， with its prevention and treatment situation becoming increasingly critical. The pathogenesis of COPD is complex， and the underlying cellular and molecular biological mechanisms remain incompletely elucidated. Programmed cell death （PCD） is the process wherein cells actively undergo demise to maintain internal environmental stability in response to certain signals or specific stimuli. Contemporary medical research indicates that the dysregulation of PCD patterns such as apoptosis， necroptosis， pyroptosis， autophagy， and ferroptosis is closely related to the onset and progression of COPD. Clarifying the molecular mechanisms of PCD in COPD may provide novel perspectives for in-depth understanding and prevention of the disease. Traditional Chinese medicine （TCM） is characterized by holistic regulation. In recent years， extensive research has been conducted in the TCM field focusing on modulating apoptosis， necroptosis， pyroptosis， autophagy， and ferroptosis for the treatment of COPD， yielding remarkable achievements. Therefore， this study systematically explored the molecular mechanism of PCD in COPD and reviewed the potential mechanisms and intervention status of TCM targeting PCD in COPD， aiming to provide insights and references for the clinical prevention， treatment and in-depth research of COPD.

Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Community-acquired pneumonia （CAP） refers to an infectious inflammation of the lung parenchyma （including the alveolar wall，that is，the broad pulmonary interstitium） acquired outside the hospital. Its common pathogens include streptococcus pneumoniae，respiratory viruses， mycoplasma pneumoniae， and so on. The related factors for the occurrence and development of CAP include patient characteristics （immune function，mucus production and clearance function，coagulation function，physical condition， and comorbidity） and pathogen characteristics （susceptibility，virulence，and antibiotic resistance）. The pathogenesis of CAP lies in immune deficiency，pathogen invasion，inflammatory response disorder，mucus production and clearance disorder， coagulation disorder， and so on. The pathogenesis of CAP in traditional Chinese medicine can be described as "vital Qi deficiency and toxic stasis". Vital Qi deficiency （lack of immunity） is the potential pathogenesis of the disease and easy to be invaded by external pathogens （respiratory pathogens）. Toxic stasis （inflammatory disorder，mucus production and clearance disorder，and coagulation dysfunction） is the key pathogenic factor. Vital Qi deficiency and toxic stasis are intermingled in a state of deficiency and excess，which suggests that the treatment of CAP lies in strengthening vital Qi and eliminating pathogenic factors. This involves strengthening vital Qi in the whole process to consolidate body resistance and nourish promordial Qi. It also involves clearing heat，eliminating phlegm，removing dampness，and dispelling stasis to dispel pathogenic toxins based on the syndrome differentiation. Its action mechanism is to regulate immune and inflammatory responses，resist pathogens，and improve mucus production and clearance， as well as coagulation disorders. Starting from the key pathogenesis of CAP，"vital Qi deficiency and toxic stasis"， this paper discussed the pathogenesis of CAP and summarized the action mechanism of vital Qi strengthening for detoxification in its treatment. It is intended to complement the theoretical system by identifying "vital Qi deficiency and toxic stasis" as the key pathogenesis underlying CAP and the scientific connotation of treating CAP with vital Qi strengthening for detoxification，thereby providing insights for its clinical application.

Tripterygium wilfordii is a traditional Chinese medicinal herb with a long history of therapeutic use but remains controversial in modern medicine because of its potent toxicity. Among its diverse chemical constituents, the diterpenoid triptolide and the triterpenoid celastrol have emerged as prominent compounds due to their remarkable pharmacological activities, including antitumor, immunosuppressive, anti-obesity, and neuroprotective effects. However, their clinical translation is limited by toxicity concerns and restricted natural availability. This review summarizes the medicinal history and chemical constituents of T. wilfordii, with particular emphasis on the pharmacological mechanisms, structural modification strategies, and recent advances in the biosynthesis of triptolide and celastrol. In addition, we discuss perspectives on toxicity mitigation and lead compound development, aiming to provide theoretical guidance and valuable references for modern drug development and the green manufacturing of T. wilfordii-derived resources.

ObjectiveTo investigate the expression of DAZ associated protein 2 （DAZAP2） in breast cancer and its effect on the biological behavior of tumor cells. MethodsThe relationship between DAZAP2 expression and patient survival was analyzed using data from The Cancer Genome Atlas （TCGA） database. Immunohistochemistry （IHC） was performed to detect DAZAP2 expression in breast cancer tissues and paratumoral tissues， and its correlation with clinicopathological characteristics was evaluated. Kaplan-Meier analysis was used to assess overall survival （OS） and recurrence-free survival （RFS） of patients with different DAZAP2 expression levels. Stable breast cancer cell lines with DAZAP2 knockdown or overexpression were established. The proliferation ability of breast cancer cells was evaluated by CCK-8 and colony formation assays， while migration and invasion abilities were detected by wound healing and Transwell assays. ResultsBioinformatics analysis and IHC results showed that DAZAP2 expression was significantly lower in breast cancer tissues than in paratumoral tissue （P<0.001）. Moreover， DAZAP2 protein expression was negatively correlated with histological grade and lymph node metastasis （P<0.05 for both）. Kaplan-Meier survival analysis revealed that low DAZAP2 expression was associated with poor prognosis in breast cancer patients （P<0.05）. The CCK-8 assay showed that， compared with the sh-Ctrl group， the proliferative activity of breast cancer cells significantly increased in the sh-DAZAP2-1 and sh-DAZAP2-2 groups （F=52.38， P<0.001）， whereas compared with the Flag group， cell proliferative activity significantly decreased in the Flag-DAZAP2 group （F=41.67， P<0.001）. The colony formation assay demonstrated that， compared with the sh-Ctrl group， the number of colonies significantly increased in the sh-DAZAP2-1 and sh-DAZAP2-2 groups （F=12.74， P<0.01）， whereas compared with the Flag group， the number of colonies was significantly reduced in the Flag-DAZAP2 group （t=9.86， P<0.001）. The wound-healing assay showed that， compared with the sh-Ctrl group， the wound closure rates significantly increased in the sh-DAZAP2-1 and sh-DAZAP2-2 groups （F=18.23， P<0.01）， whereas compared with the Flag group， the wound closure rate significantly decreased in the Flag-DAZAP2 group （t=10.42， P<0.001）. The Transwell assays showed that， compared with the sh-Ctrl group， the numbers of migrated and invaded cells significantly increased in the sh-DAZAP2-1 and sh-DAZAP2-2 groups （F=55.16 and 68.42， respectively； both P<0.001）， whereas compared with the Flag group， the numbers of migrated and invaded cells significantly decreased in the Flag-DAZAP2 group （t=6.18 and 5.73， respectively； both P<0.01）. ConclusionHigh DAZAP2 expression can delay the malignant progression of breast cancer by suppressing the proliferation， migration， and invasion of breast cancer cells.

Objective To investigate the levels and clinical significance of microRNA(miR)-17-5p and miR-141-3p in the serum of children with bacterial meningitis(BM).Methods A total of 111 children with BM ad-mitted to the First Affiliated Hospital of Xinjiang Medical University from May 2019 to May 2022 were in-cluded as the study group,and another 111 healthy children who underwent physical examinations were in-cluded as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)was used to measure the ex-pression levels of serum miR-17-5p and miR-141-3p.Pearson correlation was used to analyze the correlation between serum miR-17-5p,miR-141-3p levels and inflammatory factors in children with BM.Multivariate Lo-gistic regression was applied to analyze the influencing factors of BM occurrence.Receiver operating character-istic(ROC)curve was applied to analyze the diagnostic value of miR-17-5p and miR-141-3p levels for BM.Re-sults The serum levels of miR-17-5p and miR-141-3p in the study group were obviously lower than those in the control group(P＜0.05),while the serum levels of C-reactive protein(CRP),procalcitonin(PCT),inter-feron-γ(IFN-γ),tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,and IL-6 in the study group were high-er than those in the control group(P＜0.05).According to Pearson correlation analysis,miR-17-5p and miR-141-3p were negatively correlated with CRP,PCT,IFN-γ,TNF-α,IL-1β,and IL-6(P＜0.05).According to multivariate Logistic analysis,CRP,PCT,IFN-γ,TNF-α,IL-1β,and IL-6 were risk factors affecting the occur-rence of BM(P＜0.05),while miR-17-5p and miR-141-3p were protective factors affecting the occurrence of BM(P＜0.05).According to the ROC curve,the area under the curve(AUC)of serum level of miR-17-5p for diagnosing BM was 0.756,and the AUC of serum level of miR-141-3p for diagnosing BM was 0.720.The AUC of the combination of the two for diagnosing BM was 0.819,which was larger than that of single detec-tion(Zcombination vs.miR-17-5p=2.278,Zcombination vs.miR-141-3p=2.425,P＜0.05).Conclusion The expression levels of miR-17-5p and miR-141-3p in the serum of children with BM are reduced.The two are related to the levels of inflammatory factors,and their combined detection has a high diagnostic value for BM.

Objective To investigate the application effect of high flow humidified oxygen therapy combined with tracheotomy in elderly patients with cerebral hemorrhage and analyze the risk factors of pulmonary infection.Methods A total of 140 elderly patients with cerebral hemorrhage who underwent tracheotomy in our hospital from 2019 to 2023 were selected as the study objects,of which 93 patients receiving high-flow humidified oxygen therapy were selected as the observation group,and 47 patients receiving conventional low-flow oxygen therapy were selected as the control group during the same period.The changes of PaO2,SpO2,heart rate and mean arterial pressure were compared,and patients in the observation group were divided into infected group(n=26)and non-infected group(n=67)according to whether pulmonary infection occurred during hospitalization.The risk factors affecting pulmonary infection during hospitalization in elderly patients with cerebral hemorrhage were analyzed,and a nematographic prediction model was built to predict the risk of pulmonary infection.Results The PaO2 and SpO2 levels in observation group were higher than those in control group at 24 h and 72 h,but the respiratory rate was lower than that in control group(P＜0.05).The improvement of sputum viscosity in the observation group(68 cases of grade Ⅰ sputum and 25 cases of grade Ⅱ sputum)was better than that in the control group(16 cases of grade Ⅰ sputum,17 cases of grade Ⅱ sputum and 14 cases of gradeⅢ sputum).The rate of phlegm scab formation(0)and the number of sputum aspiration(5.15±1.08)times were lower than those in the control group[14.87％,(8.17±1.82)times](P＜0.05).There were significant differences in tracheotomy time,smoking history,bed rest time,mechanical ventilation time and nasal feeding tube retention time between infected and non-infected groups(P＜0.05).Logistic regression analysis showed that tracheotomy time＞5 d,smoking history,bed time＞10 d,mechanical ventilation time ≥24 h,nasal feeding tube retention time≥10 d were the risk factors for pulmonary infection in elderly patients with cerebral hemorrhage during treatment(P＜0.05).The AUC,sensitivity and specificity were 0.696,0.565 and 0.889 in elderly patients with cerebral hemorrhage complicated by pulmonary infection during treatment.Conclusion High-flow humidification oxygen therapy combined with tracheotomy can improve the oxygenation status in elderly patients with cerebral hemorrhage,but the time of tracheotomy,smoking history,bed rest time,mechanical ventilation time,and nasal feeding tube retention time will affect the pulmonary infection during treatment.The construction of a nomogram model based on these risk factors has higher predictive efficacy in evaluating the pulmonary infection.

Objective:To investigate the clinical utility of functional near-infrared spectroscopy (fNIRS) in evaluating cerebral function in neonates with hypoxic-ischemic encephalopathy (HIE).Methods:This was a case-control study. Fifteen neonates with moderate to severe HIE who were admitted to the Department of Neonatal Medical Center, Children's Hospital of Fudan University from March 2023 to August 2024 and completed fNIRS testing were selected as the HIE group, and 15 full-term infants without neurological diseases and completed fNIRS testing were selected as the control group during the same period. Resting-state fNIRS data were acquired to construct cerebral functional connectivity networks and topological properties were analyzed. Statistical analyses included independent t-tests, Mann-Whitney U tests, analysis of variance, and Chi-square tests. Results:Compared with controls, the HIE group exhibited significantly reduced global functional connectivity strength [0.15 (0.05-0.26) vs. 0.24 (0.13-0.35), Z=－7.66, P<0.001]. Both groups demonstrated small-world network properties, with no intergroup difference (1.17±0.05 vs. 1.14±0.05, t=2.02, P=0.050). The HIE group showed decreased shortest path length (6.22±0.52 vs. 13.74±0.49, t=48.18, P<0.001), global efficiency (0.26±0.04 vs. 0.30±0.05, t=2.50, P=0.018) and normalized shortest path length (1.50±0.07 vs. 1.62±0.22, t=2.43, P=0.020). No differences were observed in the clustering coefficient or local efficiency between the two groups. Regional analysis revealed reduced nodal efficiency in both left (0.30±0.06 vs. 0.35±0.05, t=2.47, P=0.021) and right hemispheres (0.30±0.06 vs. 0.37±0.06, t=2.68, P=0.013) in HIE neonates compared with that of the corresponding hemispheres in the control group. The intra-group comparison showed no statistical significance in node efficiency between the left and right hemispheres (both P>0.05). Conclusion:fNIRS captures functional network signatures in HIE, demonstrating clinical potential for early detection of cerebral dysfunction in neonates with hypoxic-ischemic injury.
