ObjectiveTo study the effect of Jinwei Pingchuan decoction combined with conventional Western medicine on the number of acute exacerbations， lung function， and clinical symptoms in patients with acute exacerbation of chronic obstructive pulmonary disease （COPD） with phlegm-heat obstruction in lung syndrome. MethodsA non-randomized controlled trial was conducted to include 60 patients with acute exacerbation of COPD with phlegm-heat obstruction in lung syndrome. Patients were divided into a treatment group and a control group based on whether they received Jinwei Pingchuan decoction， with 30 patients in each group. The treatment group received Jinwei Pingchuan decoction combined with conventional Western medicine therapy， while the control group received conventional Western medicine therapy alone. Both groups received treatment for 7 days. The number of acute exacerbations and lung function indices were followed up and recorded before treatment and three months after treatment. The following outcomes were observed before and after treatment： the number of acute exacerbations， lung function indices （forced expiratory volume in one second ［FEV₁］， percentage of predicted value ［FEV₁%pred］， forced vital capacity ［FVC］， and FEV₁/FVC ratio）， the degree of acute exacerbation， TCM syndrome score， COPD assessment test （CAT） score， modified British Medical Research Council Dyspnea Questionnaire （mMRC） score， C-reactive protein （CRP）， and white blood cell （WBC） count. ResultsAfter 3 months of follow-up， the treatment group showed a significant reduction in the number of acute exacerbations compared with the pre-treatment values （P<0.05）. After treatment， the treatment group had fewer acute exacerbations than the control group （P<0.05）. The degree of acute exacerbation in the treatment group improved significantly compared with the pre-treatment values （P<0.05）. After treatment， the degree of acute exacerbation in the treatment group was improved compared to the control group （P<0.05）. Regarding lung function， FEV₁， FEV₁%pred， FVC， and FEV₁/FVC ratio increased significantly in the treatment group compared with the pre-treatment values （P<0.05）， and similar improvements were observed in the control group （P<0.05）. After treatment， FEV₁ and FVC were higher in the treatment group than the control group （P<0.05）. Regarding TCM syndrome scores， the scores for individual symptoms such as wheezing， cough， expectoration， chest tightness， shortness of breath， and fatigue， as well as the total score， decreased significantly in the treatment group compared with the pre-treatment values （P<0.05）. In the control group， the scores for cough， expectoration， chest tightness， fatigue， and palpitation， as well as the total score， also decreased （P<0.05）. After treatment， the treatment group showed significantly lower scores for wheezing， cough， chest tightness， shortness of breath， and the total score than the control group （P<0.05）. Regarding the CAT score， the scores for cough， expectoration， chest tightness， climbing stairs， going out， activity， and energy， as well as the total score， decreased significantly in the treatment group compared with the pre-treatment values （P<0.05）. In the control group， the scores for cough， expectoration， chest tightness， sleep， energy， and the total score decreased （P<0.05）. After treatment， the treatment group showed significantly lower scores for cough， expectoration， chest tightness， activity， and going out than the control group （P<0.05）. Regarding the mMRC score， CRP level， and WBC count， all these parameters decreased significantly in the treatment group compared with the pre-treatment values （P<0.05）， and similar reductions were observed in the control group （P<0.05）. ConclusionJinwei Pingchuan decoction can reduce the number of acute exacerbations and the degree of acute exacerbation in patients with acute exacerbation of COPD with phlegm-heat obstruction in lung syndrome. It also improves lung function and symptoms such as cough and chest tightness， thereby enhancing the quality of life of patients.

[Objective] To investigate and summarize the clinicopathological features, diagnosis, treatment and prognosis of adrenocortical carcinoma with rhabdoid features. [Methods] The clinical diagnosis and treatment of a case of adrenocortical carcinoma with rhabdoid features admitled to Department of Urology, Weifang People's Hospital were reported.The clinical manifestations, pathological features, diagnosis and prognosis of the disease were analyzed in combination with relevant literature. [Results] A 34-year-old male patient was admitted due to scrotal distension and pain that had persisted for 6 months.Imaging examination showed a huge soft tissue tumor in the left adrenal region of the retroperitoneum with compression displacement of the left kidney, leading to obstruction of venous return in the left spermatic vein, which in turn caused varicose veins.The levels of serum renin, angiotensin, aldosterone, cortisol, and catecholamine were within normal ranges.Surgical resection of the tumor was performed, and postoperative pathological examination revealed that the tumor tissue was predominantly composed of rhabdoid cells, exhibiting positive immunohistochemical staining for INI 1, Syn, Calretinin and Vimentin.Genetic testing did not identify any deletion of SMARCB1 and SMARCA4 mutations.Therefore, the diagnosis was adrenocortical carcinoma with rhabdoid features.At the current 20-month follow-up, no recurrence or metastasis was observed.A review of the literature found that only 7 cases of this disease had been reported. [Conclusion] Adrenocortical carcinoma with rhabdoid features is a rare disease, and a definitive diagnosis is dependent upon pathological examination.Surgical resection remains the primary treatment.Long-term follow-up is essential, and further research is needed to evaluate the impact of adjuvant therapy.

ObjectiveTo observe the clinical efficacy of modified Jinwei Guben Decoction （金卫固本汤， MJGD） combined with Bailing Capsule （百令胶囊， BC） in the treatment of chronic obstructive pulmonary disease （COPD） patients in the stable stage with qi deficiency， blood stasis and phlegm obstruction syndrome， in addition to conventional western medicine treatment. MethodsA total of 102 patients with stable COPD and qi deficiency， blood stasis， and phlegm obstruction syndrome were included in the study. According to the patients'preferences， they were divided into treatment group （49 cases） and control group （53 cases）. The control group received conventional western medicine treatment， while the treatment group was given MJGD （1 dose daily） combined with BC （2.0 g each time， three times a day） additionally. The treatment period was 3 months， and the patients were followed up for 1 year after the treatment. The acute exacerbation frequency （mild， moderate， severe） before treatment， during treatment， at 6-month follow-up， and at 1-year follow-up was compared between groups. Additionally， the lung function indicators such as FEV₁， FEV₁%pred， FVC， and FEV₁/FVC ratio， traditional Chinese medicine （TCM） syndrome scores， modified British Medical Research Council （mMRC） dyspnea scale， and the COPD Assessment Test （CAT） scores before and after treatment were compared. A logistic regression model was constructed to analyze the impact of MJGD combined with BC on clinical efficacy. ResultsFour patients dropped out from the treatment group and eight from the control group， leaving 45 patients of each group for statistical analysis. The number of mild and moderate acute exacerbations in the treatment group was lower than that in the control group during the treatment period， at 6-month follow-up and within 1 year of follow-up （P＜0.05） .The number of severe acute exacerbations was only lower in the treatment group than in the control group at 6-month follow-up （P＜0.05）. Compared with that before treatment， the number of acute exacerbations of all degrees in the treatment group was significantly reduced within 1 year of follow-up （P＜0.05），while only the number of mild acute exacerbations in the control group was significantly reduced within 1 year of follow-up （P＜0.05）. The treatment group showed significant improvement in FEV₁ and FEV₁%pred and FEV₁/FEV， while the control group showed a significant decline in FEV₁ and FVC （P＜0.05）. After treatment， both groups showed significant reductions in TCM syndrome scores， including coughing， sputum， wheezing， chest tightness， shortness of breath， and fatigue， as well as mMRC and CAT scores （P＜0.05）， with the treatment group having significantly lower scores than the control group （P＜0.05）. The overall clinical effective rate of in the treatment group was 93.33% （42/45）， significantly higher than that of the control group， 75.56% （34/45， P＜0.05）. Multivariate logistic regression analysis showed that the use of MJGD combined with BC （OR = 4.68， 95%CI： 1.15 - 19.09， P = 0.03） was positively correlated with clinical efficacy. ConclusionsIn addition to conventional western medicine treatment， the combination of MJGD and BC can reduce the frequency of acute exacerbations， delay the decline of lung function， improve clinical symptoms， and significantly enhance the clinical efficacy in patients with stable COPD and qi deficiency， blood stasis， and phlegm obstruction syndrome.

Objective To explore the accuracy of artificial intelligence-based diagnosis of ovarian malignant tumors and the identification of benign and malignant tumors under transabdominal scanning and transvaginal scanning methods. Methods A dataset of transabdominal and transvaginal two-dimensional ultrasound images was used and the images were preprocessed to enhance quality. The region of interest was segmented and divided into a training set and a test set. A convolutional neural network (CNN) was trained on the images in the training set, and the accuracy of the model on the test set was calculated. Results Transvaginal scanning was 14% more accurate in diagnosing malignant ovarian tumors than transabdo-minal scanning on the test set. For identifying the benign and malignant ovarian tumors containing cystic components, a mixture of transvaginal and transabdominal scanning increased the accuracy by 9.7% over transabdominal scanning alone. Conclusion CNN can identify ovarian malignant tumors under both scanning methods, but the accuracy of transvaginal scanning is higher than that of transabdominal scanning, and the CNN model has a higher accuracy in identifying benign and malignant ovarian tumors under transvaginal scanning.

ObjectiveTo analyze the detected results of CD4⁺T lymphocytes and viral load in newly identified human immunodeficiency virus (HIV) infected patients in Huangpu District of Shanghai in 2023, to explore the correlation between them, so as to provide a scientific basis for the development of targeted prevention and control measures and antiviral treatment programs. MethodsThe data of CD4 cell count, viral load and demographic characteristics of the newly infected patients living with HIV in Huangpu District, Shanghai in 2023 were collected and analyzed by using descriptive epidemiological method. ResultsThe mean CD4 cell count of the 67 newly identified HIV infected patients in Huangpu District was (301.22±235.19) cells·µL^-1, with a mean viral load of (5.15±1.28) ×10⁵ copies·mL^-1.There were statistically significant differences in CD4 cell count and viral load among different age groups (P<0.05), but there were no statistically significant differences by gender and marital status (both P>0.05). The CD4 cell count and CD4/CD8 ratio both were negatively correlated with the lg value of viral load (r=-0.290, -0.378; P=0.027, 0.002). ConclusionThe CD4 cell counts of the newly identified HIV infected patients in Huangpu District in 2023 were generally low, the proportion of patients with high viral load was high, but the risk for elderly infected with HIV was high. The elderly have gradually become the key population for AIDS prevention and control in Huangpu District. It is recommended to expand HIV screening in the elderly to reduce the risk of HIV transmission and increase the rate of early detection and treatment.

Objective To investigate the protective effect and mechanisms of total alkaloids of Bulbus Fritillaria Pallidiflora (TA-BFP) on pulmonary fibrosis in silicosis mice. Methods i) Bulbus Fritillaria Pallidiflora (BFP) powder was collected by heating and refluxing twice with 70.00% ethanol, and the dried concentrated sample was purified using cation-exchange and macroporous adsorbent resins to obtain TA-BFP. The total alkaloids level was detected using ultraviolet spectrophotometry and the characteristic peaks in TA-BFP were identified using the high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD). ii) Specific pathogen-free male C57BL/6J mice were randomly divided into the control group, model group and intervention group, with 15 mice in each group. Mice in the model group and the intervention group were treated with 80 μL silica suspension with a mass concentration of 62.5 g/L, while the control group was treated with an equal volume of 0.9% sodium chloride solution using non-exposed tracheal instillation method. On the 28th day after modeling, mice in the intervention group were given TA-BFP at a dose of 60 mg/kg body mass, and the model group and control group were given 2.00% Tween-80 solution at the same volume by gastric gavage, once per day, for 28 days. The mouse lung tissue pathology was observed, lung organ coefficient was calculated, and inflammation and fibrosis scores were assessed after the intervention period. Serum levels of mouse interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α) were measured by enzyme-linked immunosorbent assay. Results i) The total alkaloid level of TA-BFP in the BFP powder was 50.36% after elution and purification. A total of nine alkaloid components in TA-BFP were identified by HPLC-ELSD. ii) The results of lung histopathology showed that no obvious changes of inflammation and fibrosis were identified in the lungs of mice in the control group, obvious changes of inflammation and fibrosis were identified in the lungs of mice in the model group, and the intervention group showed reduced inflammation and fibrosis in the lungs of mice compared with that of the model group. The lung organ coefficient, pulmonary inflammation score, pulmonary fibrosis score, and levels of serum IL-1β, IL-6, and TNF-α were significantly higher in the model group than those in the control group (all P<0.05). The lung organ coefficient, pulmonary inflammation score, pulmonary fibrosis score, and levels of serum IL-1β, and TNF-α were significantly higher in the intervention group than those in the control group (all P<0.05), while the pulmonary inflammation score, pulmonary fibrosis score, and levels of serum IL-1β, IL-6, and TNF-α were significantly lower in the intervention group than those in the model group (all P<0.05). Conclusion TA-BFP alleviates pulmonary inflammation in silicosis mice, thereby delaying the progression of pulmonary fibrosis. The mechanism may involve in inhibiting the expression of inflammatory factors IL-1β, IL-6, and TNF-α.

Objective To analyze the current situation of the knowledge-attitude-practice among noise-exposed workers at an airport apron. Methods A total of 494 noise-exposed workers from an airport apron were selected as the study subjects using the judgmental sampling method. A self-designed "Occupational Protection Knowledge, Attitudes, and Practices Questionnaire" was used to assess the current situation of knowledge-attitude-practice on occupational protection. Results Regarding the awareness of noise hazards among the study subjects, the awareness rates of noise-induced impairment on digestive function and reproductive system were the lowest (44.9% and 37.7%, respectively). The awareness rate of noise-induced negative emotions increased with length of service (P<0.01). Regarding the occupational protection knowledge for noise, the awareness rate of occupational noise-induced deafness was “incurable” was the lowest (39.1%). The support rate for five kinds of occupational protection attitudes for noise was generally >85.0%, while only 58.3% of the study subjects consistently or frequently wearing earplugs during work. The most common source of noise hazard and protection knowledge was pre-employment training (76.9%), followed by occupational disease prevention and control campaigns (76.1%). Conclusion Noise-exposed workers in this airport apron have incomplete awareness of non-auditory system hazards caused by noise, and the awareness of knowledge of some occupational protection is relatively low. Although their attitudes toward occupational protection are positive, many workers still fail to consistently wear personal protective equipment at work.

[Objective] To obtain accurate data on alanine aminotransferase (ALT) levels among blood donors in China and to explore the necessity of adjusting the qualification criteria for ALT. [Methods] A collaborative study was conducted involving 26 blood centers and 7 central blood stations with an annual testing volume exceeding 100 000 samples. Between December 1 and 15, 2024, pre-donation ALT testing was suspended for 1-2 days for all whole blood donations. ALT levels were measured only post-donation using standard laboratory equipment and reagents. All transfusion-transmitted infectious disease-related serological and nucleic acid testing, including hepatitis E virus (HEV) RNA testing, were performed. Within one week of testing completion, anonymized data on basic donor information, routine test results, and HEV RNA results were collected and statistically analyzed. [Results] A total of 21 345 blood donors were included in the study, with an ALT disqualification rate of 7.6% (1 623/21 345). The disqualification rate was 9.6% (1 453/15 205) for males and 2.8% (170/6 140) for females. There were significant regional variations in both the disqualification rates and levels of ALT, with Shaanxi Province exhibiting the highest disqualification rate (12.3%, 87/710) and Yunnan Province the lowest (2.9%, 19/652). Among the provinces (autonomous regions and municipalities), Beijing recorded the lowest ALT levels. ALT levels varied across different age groups and genders. Among all samples tested by HEV RNA, the HEV RNA positive rate was 0.29‰ (6/21 003). HCV infection was found to directly affect ALT levels, while HBV, HIV, syphilis, and HEV infections did not significantly impact ALT disqualification rates. It is recommended to adjust the ALT qualification criteria to twice the upper limit of the clinical reference range, which would increase the number of eligible blood donations by 6.61% (1 293/19 550). [Conclusion] In China, the ALT levels of blood donors are correlated with gender, age, geographical region, and HCV infection status. Appropriately raising the ALT eligibility criteria to ≤100 U/L for male donors and ≤80 U/L for female donors could expand the pool of eligible donors and reduce the blood discard rate while ensuring blood safety.

OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2 diabetes mellitus（T2DM）poorly controlled with metformin. METHODS Based on the perspective of China’s health system， a Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio（ICER） and incremental net monetary benefit （INMB） were calculated using one time the 2024 per capita gross domestic product（GDP） as the willingness-to-pay（WTP） threshold. One-way sensitivity analysis， probability sensitivity analysis and scenario analysis were conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin， ICER of semaglutide combined with metformin was 260 485.67 yuan/quality-adjusted life year （QALY），which was higher than the WTP threshold set in this study （95 749 yuan/QALY），and the corresponding INMB was －61 576.24 yuan，indicating that the canagliflozin + metformin regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had the greatest influence on INMB，but changes in parameters within the selected range did not drive decision reversal. With the increasing of WTP threshold，the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP threshold，the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost- effective. CONCLUSIONS From the perspective of China’s health system， canagliflozin + metformin is more cost-effective than semaglutide + metformin for T2DM patients yueru. with poor glycemic control with metformin alone.
