Tracheobronchial adenoid cystic carcinoma （TACC） is a low-grade malignant tumor originating from the airway mucosa. Despite its slow progression，it is characterized by high invasiveness，frequent recurrence，and a strong tendency for metastasis. Preclinical studies have shown that vascular-targeted therapy holds significant potential. However，an effective systemic treatment for TACC has not been established yet. This study explored TACC from the perspective of "Feiji" in traditional Chinese medicine （TCM） as the starting point. It deeply investigated the mechanisms of abnormal collaterals and tumor vascular recruitment and further elaborated on the theoretical connection between abnormal collaterals and tumor vascular recruitment. Firstly，collateral hyperactivity led to disordered and erratic pulmonary collaterals. Their abnormal structures were similar to the disorderly and tortuous nature of tumor （pseudo）angiogenesis. This resulted in imbalances in the functions of circulation，perfusion，and reverse injection of the pulmonary collaterals，and then led to unrestrained collateral dysfunction and the accumulation of pathogenic factors. Secondly，the remodeling of the extracellular matrix （ECM） and epithelial-mesenchymal transition （EMT） in TACC were critical processes in vascular co-option （VCO），representing the micro-level manifestation of the displacement of nutrient and defense. During this process，ECM remodeling made TACC cells more likely to hijack normal blood vessels，creating a complex vascular microenvironment conducive to tumor growth. In terms of treatment，this study proposed a TCM strategy of "regulating collaterals to expel pathogenic factors and nourishing collaterals to strengthen the healthy Qi"，and listed potential TCM. These were intended to regulate the Qi and blood in the collaterals，repair the functions of abnormal collaterals，and intervene in the vascular recruitment process of TACC. Future research should focus on improving the TCM clinical syndrome characteristics of TACC. Through modern molecular biology techniques，it is necessary to deeply analyze the micro-level pattern of vascular recruitment in TACC. This would enrich the understanding of the profound connection between abnormal collaterals and tumor vascular recruitment，providing empirical evidence for TCM-targeted therapies for vascular recruitment in TACC.

OBJECTIVE To provide technical support for improving recognition rate of adverse drug events （ADEs） related to traditional Chinese medicine （TCM） formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool （GTT） whitepaper， literature on adverse reactions to TCM， and expert review opinions， ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023， utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established， including thirty-two laboratory test indexes， thirteen clinical symptoms， and three antidotes. Among the 1 682 patients included， GTT identified 652 potential ADEs， 284 true positive ADEs，with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor， 278 cases of ADEs were finally confirmed， with an incidence rate of 16.53%， significantly higher than the number of spontaneously reported ADEs during the same period （0）. The 278 cases of ADEs were mostly grade 1 （223 cases）， mainly involving hepatobiliary system， gastrointestinal system， blood- lymphatic system， etc；a total of 219 types of TCMs are involved，and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos， Codonopsis pilosula， Atractylodes macrocephala， fried Glycyrrhiza uralensis， and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

OBJECTIVE To investigate the effects of peiminine B （PEI） on Streptococcus pneumoniae （SP）-induced alveolar epithelial cell injury by regulating the Ras-related C3 botulinum toxin substrate 1 in nucleus accumbens （Rac1）/protein kinase B （Akt）/nuclear factor κB （NF-κB） signaling pathway. METHODS Human alveolar epithelial cells （HPAEpiC） were taken and randomly divided into the Control group， SP group （1×108 cfu/mL SP bacterial solution）， low-， medium-， and high-concentration PEI groups （1×108 cfu/mL SP bacterial solution+0.05， 0.10， 0.20 mmol/L PEI）， and high-concentration PEI+Akt activator group （P-H+SC79 group， 1×108 cfu/mL SP bacterial solution+0.20 mmol/L PEI+10 μmol/L SC79）. Except for the Control group， the other groups of cells were treated with SP bacterial solution and/or corresponding drug solution. After 24 h of treatment， the levels of inflammatory factors （interleukin-6， -18， -1β） in the supernatant solution， the contents of oxidative stress indexes [lactate dehydrogenase （LDH）， reactive oxygen species （ROS） and superoxide dismutase （SOD）]， apoptosis rate， as well as the expressions of proliferation/apoptosis-related proteins [cyclin-dependent kinase 1 （CDK1）， B cell lymphoma-2 related X protein （Bax）] and pathway-related proteins （Rac1， Akt， phosphorylated Akt， NF-κB and phosphorylated NF-κB） were detected in each group. RESULTS Compared with the Control group， the levels of inflammatory factors in supernatant solution， LDH and ROS contents， apoptosis rate， the protein expressions of Bax and Rac1 and the phosphorylation levels of Akt and NF-κB in the SP group were significantly increased or up-regulated， while SOD content and the protein expression of CDK1 were significantly decreased or down-regulated （P＜0.05）. Compared with the SP group， the above indexes in PEI groups were significantly improved in a concentration-dependent manner （P＜0.05）. SC79 could significantly reverse the improvement effect of the high concentration of PEI （P＜0.05）. CONCLUSIONS PEI can alleviate SP-induced inflammation and oxidative stress damage of alveolar epithelial cells and inhibit apoptosis， which may be achieved by inhibiting Rac1/Akt/NF-κB signaling pathway.

ObjectiveTo develop a classification model based on complete blood count （CBC） parameters combined with clinical factors to predict severe respiratory infections caused by Human adenovirus （HAdV） in pediatric patients. MethodsFrom September 2023 to September 2024， the CBC parameters and related clinical data from pediatric patients diagnosed with HAdV infection were collected. Principal component analysis and random forest models were used to identify potential predictors of severe cases. ResultsA total of 668 pediatric patients were included， with 564 cases assigned to the training cohort and 104 cases to the validation cohort. Severe cases were defined as pneumonia and/or fever lasting ≥5 days （pneumonia or prolonged fever， PorPF）. Principal component analysis and feature importance analysis （Mean Decrease Gini value） identified the monocytosis ratio （PMono）， red blood cell count （RBC）， and platelet count （PLT） as the most critical CBC parameters. Logistic regression analysis revealed that oxygen therapy （OR = 4.367， 95% CI： 1.568–12.161） and increased work of breathing （OR = 3.904， 95% CI： 2.146–7.101） were relative risk factors for PorPF. Meanwhile， higher PMono （OR = 0.696， 95% CI： 0.640–0.757）， RBC （OR = 0.201， 95% CI： 0.124–0.325）， and PLT （OR = 0.990， 95% CI： 0.987–0.994） were protective factors. When PMono was used as a predictive marker for PorPF， the area under the receiver operating characteristic curve （AUC） was 0.648 and 0.705， respectively. A random forest model incorporating four risk factors ［PMono， RBC， PLT， and hematocrit （HCT）］ was constructed to classify PorPF and general cases， achieving AUCs of 0.688 and 0.768， respectively. ConclusionsPMono， RBC， and PLT may serve as characteristic CBC indicators for predicting pneumonia or prolonged fever in children with HAdV infection. A risk factor model built using PMono， RBC， PLT， and HCT offers a relatively simple and accurate approach to predicting severe cases in pediatric HAdV infections.

Objective To compare the clinical efficacy between liposuction combined with circumareolar small incision and three-port endoscopic surgery for the treatment of Simon Ⅱ gynecomastia (GYN). Methods Comparative case data of 120 patients with GYN were retrospectively analyzed, 61 patients in the open group underwent circumareolar small incision mastectomy after liposuction, and 59 patients in the endoscopic group underwent three-port endoscopic mastectomy after liposuction. The two groups were compared in terms of surgery-related indexes, occurrence of postoperative complications and patient satisfaction. Results The unilateral operation time of the open group was shorter than that of the endoscopic group, the unilateral gland resection weight in the open group was more than that in the endoscopic group, the hospitalization cost of the open group was less than that of the endoscopic group (all P<0.01). There was no significant difference in unilateral liposuction volume, drainage volume on the first postoperative day, and time to drain removal between the two groups (P>0.05). The incidence of complications in the open group and the endoscopic group were 8.2% and 13.6% respectively, and there was no significant difference between the two groups (P>0.05). The difference in the overall satisfaction scores between the two groups was not statistically significant (P>0.05). Conclusions Liposuction combined with circumareolar small incision or three-port endoscopic surgery both has good cosmetic effects in the treatment of Simon Ⅱ GYN. The operation with circumareolar small incision is simple, has a shorter operation time, costs less, and does not require special equipment, which is suitable for promotion and application in medical institutions.

Mitochondria are the main site of energy metabolism in cardiomyocytes， and at the same time mediate apoptosis and immune response， so mitochondrial dysfunction is closely related to the development of heart failure. Combined with the pathogenesis of mitochondrial dysfunction and heart failure， it is proposed that the mitochondrial function is similar to "sweat pore - collaterals - zang and fu organs"， according to which the treatment of heart failure is based on the theory of "sweat pore - collaterals - zang and fu organs". It is believed that the core mechanism of heart failure is qi deficiency， and qi deficiency leads to the weakness of the sweat pore opening and closing， or even the sweat pore closure， then resulting in qi deficiency and blood stasis， collaterals stagnation fail to flourish， and qi， blood， and body fluids can not infiltrate and nourish zang-fu organs， so that the heart fail to be nourished， and the disease will develop. The treatment should be based on the method of boosting qi and opening sweat pore， using acridity to unblock the collaterals， and invigorating blood and draining water， with medicinal of boosting qi， invigorating blood， and draining water as treatment.

Background As a key to economic and social development, occupational groups with low levels of occupational health literacy (OHL) are considered vulnerable groups with high risks of work-related diseases and injuries. Therefore, improving the OHL of these groups is of great significance in reducing the burden on public health. Objective To master the four dimensional OHL levels and influencing factors of the key groups in Fuling District, Chongqing, and provide a basis for formulating health education programs for occupational groups in the future. Methods The Occupational Health Literacy Questionnaire of Key Populations was distributed online to investigate the key occupational groups in Fuling District through stratified cluster sampling. The survey collected data on basic demographic information, legal knowledge of occupational health, basic knowledge of occupational health protection, basic skills of occupational health protection, and healthy working style and behavior. Univariate analysis, logistic regression, and nomogram were used to analyze the above data. Results This survey distributed 4824 questionnaires, of which 4677 were valid, with a recovery rate of 97.0%. The dimensional OHL levels of key occupational groups in Fuling District from high to low were: healthy working style and behavior (79.1%), basic knowledge of occupational health protection (78.4%), legal knowledge of occupational health protection (43.3%), and basic skills of occupational health protection (37.6%). The results of logistic regression showed that the occupational health legal knowledge levels in the groups of high school/vocational high school/technical secondary school and above (reference: primary school and below) (OR=1.47, 95%CI: 1.05, 2.05), ≥3000 yuan of monthly income (reference: <3000 yuan of monthly income) (OR=1.39, 95%CI: 1.06, 1.84), and medium enterprises (reference: micro enterprises) (OR=1.84, 95%CI: 1.29, 2.63) were higher; the occupational health legal knowledge level in the electricity, heat, gas, and water production and supply industry was lower than that in the mining industry (OR=0.68, 95%CI: 0.47, 0.97); the basic knowledge levels of occupational health protection in the groups of ≥ 3 years of service (reference: < 3 years of service) (OR=0.78, 95%CI: 0.65, 0.94) and medium enterprises (reference: large enterprises) (OR=0.78, 95%CI: 0.64, 0.95) were lower; the basic knowledge level of occupational health protection in the ethnic minorities was higher than that in the Han ethnic group (OR=1.73, 95%CI: 1.04, 2.87); the occupational health protection basic skill level in the group of ≥ 3 years of service (reference: < 3 years of service) (OR=0.69, 95%CI: 0.60, 0.79) was higher; the level of healthy working style and behavior in the group of ≥ 11 years of service (reference: < 3 years of service) (OR=0.73, 95%CI: 0.59, 0.89) was lower; the level of healthy working style and behavior in the group of high school/vocational high school/technical secondary school and above (reference: primary school and below) (OR=1.60, 95%CI: 1.15, 2.23) was higher. The nomogram showed that educational level and monthly income had the greatest impact on the occupational health legal knowledge level; length of service had the greatest impact on the basic knowledge of occupational health protection level and the healthy working style and behavior level. Conclusion In the future, the focus of health education and health promotion in Fuling District should be implemented to improve the basic skills of occupational health protection and the legal knowledge of occupational health, especially for workers with low education, low income, from micro enterprises, and on the job, so as to improve their skills of occupational health protection and legal knowledge, and to control the occurrence of occupational or work-related diseases.

Vaccination is a main measure for protecting chickens against Marek's disease,while it is not able to suppress the infection,proliferation,transmission,and virulence enhancement on Marek's disease virus.Inhibiting the proliferation of Marek's disease virus in chicken is therefore an im-portant option for enhancing defense effectiveness.In this study,a compound,DUBs-IN-1,was found to inhibit the activity of MDV049,a protease encoded by Marek's disease virus,via screening a protease inhibitor library using MDV049 as target and ubiquitin probe.Molecular docking re-vealed that DUBs-IN-1 can interact with the residues which formed the catalytic pocket of MDV049,blocking the interaction between Ub substrate and the catalytic center of MDV049,then suppress the activity of MDV049 with competitive inhibition.Using the CPE model,it was found that DUBs-IN-1 at the concentration of 0.35 and 0.70 μmol/L significantly inhibited the CPE in-duced by Marek's disease virus in CEF cells.Quantitative analysis revealed that DUBs-IN-1 inhibi-ted the proliferation of Marek's disease virus in CEF cells(P＜0.01).Furthermore,it was found that the administration of 80 and 150 pg/(kg·d)of DUBs-IN-1 in chicken infected by Marek's disease virus significantly inhibited the proliferation of MDV in T cells(P＜0.01).In summary,this study demonstrated that the compound DUBs-IN-1 is able to inhibit the proliferation of Marek's disease virus in chicken cells,laying a theoretical and practical foundation for further de-velopment of the drugs against Marek's disease virus.
