Objective:s To investigate the risk factors for delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) in patients with acute carbon monoxide poisoning (ACOP) and to develop predictive models based on machine learning algorithms.Methods:Patients with ACOP hospitalized at the First Affiliated Hospital of Zhengzhou University from August 2019 to October 2024 were included, with the occurrence of DEACMP as the outcome measure. The dataset was randomly divided into training and validation sets at a ratio of 7:3. Lasso regression was used to select features influencing the outcome in training sets. Nine machine learning models—including Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Support Vector Machine (SVM)—were constructed. Receiver operating characteristic (ROC) curves were plotted and the area under the curve (AUC) calculated for each model. Calibration curves were used to assess accuracy, and decision curve analysis (DCA) was applied to evaluate clinical utility. The SHapley Additive exPlanations (SHAP) method was employed to visualize and interpret the best-performing model.Results:A total of 264 ACOP patients were included, of whom 54 (20.5%) developed DEACMP. Lasso regression identified eight key feature variables. Based on these factors, predictive models were constructed, showing good AUC stability across the nine machine learning models in both training (0.92–0.99) and validation sets (0.85–0.91). The RF model performed best, with an AUC of 0.99 in the training set and 0.90 in the validation set; its calibration curve and DCA curve also demonstrated excellent performance. SHAP analysis of the RF model revealed the importance ranking of factors from highest to lowest as follows: Glasgow Coma Scale (GCS) score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, diastolic blood pressure (DBP), and drinking history.Conclusions:The RF model exhibited the highest predictive performance for DEACMP occurrence in ACOP patients. The influencing factors, ranked in order of importance from highest to lowest, are as follows: GCS score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, DBP, and drinking history.

A bladder cancer patient underwent intravesical Bacillus Calmette-Guérin (BCG) instillation in Xiamen Branch, Zhongshan Hospital, Fudan University in April 2023. Following 8 instillations the patient presented with fever, cough and dyspnea, and was diagnosed as interstitial pneumonia (IP). Symptoms resolved after anti-tuberculosis and methylprednisolone treatment, with subsequent successful discharge. Using the keywords ′Bacillus Calmette-Guérin, ′ ′intravesical instillation, ′ ′pneumonia, ′ Wanfang Data, China National Knowledge Infrastructure(CNKI), Weipu(VIP), and PubMed databases were searched for relevant literature published between January 2014 and June 2024, and 20 cases of BCG instillation-induced pneumonia were retrieved, including 10 IP cases and 10 miliary pneumonia cases. Among 10 IP cases, 7 received corticosteroids combined with anti-tuberculosis therapy. Two cases unresponsive to combination therapy resulted in mortality, while others showed therapeutic efficacy. Miliary pneumonia demonstrated better prognosis, with 6 cases achieving complete remission through anti-tuberculosis monotherapy. The results indicate that severe BCG-related pneumonia generally necessitates combined anti-tuberculosis and corticosteroid therapy.

Aging, a complex and multisystem process, has increasingly become a hot issue of global concern. Traditional Chinese medicine has accumulated rich understanding of aging during thousands of years of development, which provides valuable references for the in-depth study of overall aging. According to the Qi-collateral theory in traditional Chinese medicine, essence is the origin of life; Qi is the driving force of life; and spirit is the embodiment of life. This theory interprets key scientific issues such as the formation of life, the driving force of life, the function of Zang-Fu organs, and the spirit and consciousness. Furthermore, it reveals the key mechanism of aging. That is, the deficiency of kidney essence is the root of aging; the loss of vitality is the key of aging; and the depletion of body and spirit is the manifestation of aging. Based on the experience of medical practitioners in the past dynasties, such as nourishing essence, black food tonifying the kidney, and supplementing essence with flesh-blood products, the treatment method of invigorating kidney and supplementing essence, harmonizing Yin and Yang, reinforcing the vitality, and nourishing the body and spirit was proposed. Furthermore, an innovative Chinese patent medicine, Bazi Bushen capsules, is developed, which exerts the antiaging effect by replenishing Qi, invigorating the spirit, and nourishing the body and spirit. Pharmacological and clinical studies have confirmed that this preparation has antiaging effects and are effective in the prevention and treatment of age-related diseases. Experimental studies have shown that Bazi Bushen capsules can delay the overall aging, reduce the DNA methylation and extend the healthy life of naturally aging mice, mitigate the age-related cognitive dysfunction, improve neurological function, maintain redox homeostasis and telomere integrity, and inhibit apoptosis. Moreover, Bazi Bushen capsules can increase the dermal thickness and the collagen fiber and elastic fiber content to prevent skin aging. In addition, Bazi Bushen capsules can correct the lipid metabolism disorders and ameliorate multisystem age-related diseases such as osteoporosis in surgically induced menopausal rats. This article discusses the pathogenesis, treatment, and prescription of aging and the antiaging theory, aiming to provide a basis for delaying aging and preventing related diseases.

Metabolic regulation has been proven to play a critical role in T cell antitumor immunity. However, cholesterol metabolism as a key component of this regulation remains largely unexplored. Herein, we found that the low-density lipoprotein receptor (LDLR), which has been previously identified as a transporter for cholesterol, plays a pivotal role in regulating CD8

Strain-resource engineering is often considered as an important infrastructure of microbiology related research and industry. The western developed countries took the lead in establishing the classical microbial resource utilization method, and continuously improved the preservation system, species annotation technology and global sharing mechanism, which realized the expansion and reserve of biological resources since end of the 19th century. The rich and diversified germplasm resources, standard strains and production strains not only have important economic values, but also maintain the advantages of scientific research, bioeconomy (such as antimicrobial agents, vaccines, detection reagent development and standard development, etc.) and national security. Although there has been a lot of progress in related research in recent years, compared with developed countries, there is still a big gap in related fields in China. The investment and top-level design in this area lag far behind the western developed countries, and it is not commensurate with the current level of economic and social development in my country. Drawing lessons from the practice of WFCC and WDCM (World Data Center for Microorganisms, Global microbial data Center, affiliated to WFCC), for the purpose of collecting new clinical species/strains, this paper puts forward some suggestions on the identification, preservation and upload system of isolates.
