Objective To investigate the acceptance and satisfaction of tuberculosis prevention and control personnel in Beijing with the patient management system, and to provide a basis for further improving the patient management model. Methods A survey was conducted on the current usage, satisfaction, willingness to use and system improvement opinions of the patient management system among medical staff involved in the supervision and medication management of pulmonary tuberculosis patients in Beijing. Results A total of 360 medical staff participated in the survey. “Patient management” was the function with the largest number of users, accounting for 96.94%. The proportion of users of each module who believed that the module's design met actual work needs was over 90%. About 94.44% of respondents believed that patient management systems facilitated the transfer and sharing of information between institutions. And 90.83% of respondents thought that the patient management system was easy to operate, and 89.17% of respondents believed that patient management systems reduced workload. About 97.50% of respondents were satisfied with the overall use of the patient management system. The results of the influencing factor analysis showed that those with 3 or less modules designed to meet actual work were less satisfied than those with more than 3 modules, and the difference was statistically significant (P=0.001). Respondents put forward suggestions for improvement on the optimization of operational details such as system response speed, interface design, system login and query statistics. Conclusion Medical staff involved in the follow-up management of pulmonary tuberculosis patients are highly satisfied with their work using the patient management system. During the promotion and use, it is still necessary to continuously optimize the system functions according to work needs so that the system can truly facilitate work.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

OBJECTIVE To investigate the protective effect and mechanism of saikosaponin C (SSC) on acute liver injury (ALI) in mice induced by carbon tetrachloride (CCl4) based on serum metabolomics. METHODS Forty mice were divided into blank group (water), model group (water), positive control drug group (Biphenyl diester drop pills, 150 mg/kg), and SSC low- and high-dose groups (2.5, 10 mg/kg) using the random number table method, with 8 mice in each group. They were given water/ relevant drugs, once a day, for 7 consecutive days. One hour after the last administration, all mice were intraperitoneally injected with 0.2% CCl4 olive oil to induce ALI model, except for the blank group. After 17 hours of the modeling, the liver index of mice was calculated. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-1β in serum of mice were detected. The histopathological changes of liver tissue were observed. Meanwhile, the serum metabolomics of mice were analyzed by liquid chromatography-mass spectrometry. RESULTS Compared with the blank group, the levels of liver index, ALT, AST, LDH, TNF-α, IL-6, and IL-1β in the model group were significantly increased (P<0.01). Hepatocytes were edema, vacuolar degeneration, more necrosis, and a large number of inflammatory cells were infiltrated. Compared with the model group, liver index and serum index levels of mice were significantly decreased (P<0.05 or P<0.01), accompanied by marked improvement in histopathological damage to the liver tissue. The metabolomics results showed that compared with the model group, there were 63 up-regulated and 256 down-regulated differential metabolites in the serum of mice in the SSC high-dose group, including prostaglandin B2, 20-hydroxy-leukotriene B4, 5- hydroxy-L-tryptophan, 7α -hydroxycholesterol, etc.; these metabolites were primarily involved in metabolic pathways such as arachidonic acid metabolism, 5-hydroxytryptamine synapse, primary bile acid biosynthesis. CONCLUSIONS SSC exerts a protective effect against CCl4-induced ALI by down-regulating the level of key metabolites such as prostaglandin B2 and 20-hydroxy-leukotriene B4, and then ruducing metabolic pathways such as arachidonic acid metabolism, 5- hydroxytryptamine synapse, and primary bile acid biosynthesis.

Objective To study the effect of Mycobacterium tuberculosis (Mtb) Pro-Pro-Glu-59 (PPE59) protein on the biological function of Mycobacterium smegmatis (Ms) and the regulation of host cell immune response. Methods PPE59 gene fragment was obtained by PCR amplification, cloned into pALACE, constructed into recombinant pALACE-PPE59 vector, and electro-transformed into Ms. Western blot was applied to analyse PPE59 expression and subcellular localization. The survival of Ms_Vec and Ms_PPE59 under low acid (pH=3 and pH=5) conditions and active surface pressure sodium dodecyl sulfate (SDS) conditions and their intracellular survival in macrophages were analyzed. ELISA was used to detect the cytokine (IL-1β, IL-6, IL-12, TNF-α and IL-10) expression levels of Ms_Vec and Ms_PPE59 infected macrophages. Results PPE59 protein localized to the cell wall of Ms can enhance the acid-resistance and anti-SDS effect of Ms, which is conducive to the survival of Ms in macrophages. PPE59 significantly decreased the secretion levels of pro-inflammatory cytokines (IL-1β, IL-6, IL-12 and TNF-α), and promoted the secretion levels of anti-inflammatory cytokine (IL-10). Conclusion PPE59 enhances the survival ability of Ms under low acid and SDS pressure and promotes its intracellular survival by regulating the cytokine secretion levels.

Aconitum (Ranunculaceae) has a long-standing history in traditional Chinese medicine (TCM), where it has been widely used to treat conditions such as rheumatoid arthritis (RA), myocardial infarction, and heart failure. However, the potency of Aconitum alkaloids, the primary active components of Aconitum, also confers substantial toxicity. Therefore, assessing the efficacy and toxicity of these Aconitum alkaloids is crucial for ensuring clinical effectiveness and safety. Metabolomics, a quantitative method for analyzing low-molecular-weight metabolites involved in metabolic pathways, provides a comprehensive view of the metabolic state across multiple systems in vivo. This approach has become a vital investigative tool for facilitating the evaluation of their efficacy and toxicity, identifying potential sensitive biomarkers, and offering a promising avenue for elucidating the pharmacological and toxicological mechanisms underlying TCM. This review focuses on the applications of metabolomics in pharmacological and toxicological studies of Aconitum alkaloids in recent years and highlights the significant role of metabolomics in exploring compatibility detoxification and the mechanisms of TCM processing, aiming to identify more viable methods for characterizing toxic medicinal plants.

Osteoporosis and knee osteoarthritis often co-occur and are closely related in terms of epidemiology, clinical symptoms, pathogenesis and other aspects. Therefore, it is necessary to manage the co-morbidity and treat the two as a whole. Based on the overall relationship between wei (痿) and bi (痹) in TCM, it is believed that osteoporosis and knee osteoarthritis have marrow loss and bone atrophy as the core pathogenesis of co-morbidity, and microfractures as the central pathological link. The overall treatment is rooted in boosting kidney, supplementing marrow and strengthening the bones. According to the pathological manifestations of microfractures in the process of co-morbidity, and the different deficiency and excess characteristics of wei and bi, it can be divided into three types, "wei emerging with mild bi", "wei and bi progressing simultaneously", and "emphasis on both wei and bi", for treatment. In terms of "wei emerging with mild bi", that is the early stage of osteoporosis, the traditional Daoyin (导引) is the main therapy. For "wei and bi progressing simultaneously", it can be divided into three stages further, including the onset stage, remission stage, and recovery stage of knee pain, treated with Taohong Siwu Decoction (桃红四物汤), Bushen Huoxue Formula (补肾活血方) and self-made Bushen Qianggu Formula (补肾强骨方) as the main formula respectively. For "emphasis on both wei and bi", the proven formula, Qianggu Zhitong Formula (强骨止痛方), is taken as the main prescription.

Objective:
To investigate the association between high normal blood pressure, hypertension and microalbuminuria (MAU), so as to provide the basis for early screening and prevention of renal injury caused by hypertension.
Methods:
A multi-stage cluster random sampling method was used to select permanent residents aged 18 to 75 years from six provinces including Hebei, Hunan, Sichuan, Heilongjiang, Qinghai and Jiangxi from September to October 2021. Basic information and lifestyle behaviors were collected through questionnaires. Indices including height, weight and blood pressure were measured. Urinary microalbumin and creatinine were measured in 24-hour urine samples. The associations between high normal blood pressure, hypertension, and MAU were analyzed by using a multivariable logistic regression model.
Results:
A total of 1 982 residents were surveyed, with 996 residents aged <50 years (50.25%) and 986 residents aged ≥50 years (49.75%). There were 958 males (48.34%) and 1 024 females (51.66%). Normal blood pressure was observed in 653 residents (32.95%), high normal blood pressure in 748 (37.74%) and hypertension in 581 (29.31%). MAU was detected in 164 participants, with a detection rate of 8.27%. The detection rates of MAU among residents with normal blood pressure, high normal blood pressure, and hypertension were 2.14%, 8.16% and 15.32%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, smoking, alcohol consumption, regular exercise and body mass index, the residents with high normal blood pressure (OR=3.535, 95%CI: 1.898-6.585) and hypertension (OR=7.232, 95%CI: 3.808-13.732) had higher risks of MAU compared to those with normal blood pressure; the residents with hypertension (OR=1.914, 95%CI: 1.340-2.735) had a higher risk of MAU compared to those with high normal blood pressure.
Conclusions
High normal blood pressure and hypertension are associated with an increased risk of MAU.

Tingli Dazao Xiefeitang is a classic formula for treating lung abscesses and thoracic fluid retention, recognized throughout history and included in the Catalogue of Ancient Classic Formulas (Second Batch). This article employs bibliometric methods to investigate and analyze the source, origin, and key information of Tingli Dazao Xiefeitang, providing a theoretical basis for the development and application of this renowned formula. The results show that Tingli Dazao Xiefeitang first appears in Synopsis of the Golden Chamber (Jin Kui Yao Lue), where three clinical applications are recorded. The original text clearly states that this formula is used to treat lung abscesses and thoracic fluid retention, with symptoms such as inability to lie down due to wheezing, chest and rib fullness, facial edema, inability to rest due to thoracic fluid retention, and cough inversion. This aligns with findings from ancient application research. In later generations, the methods proposed by ZHANG Zhongjing were predominantly used for medication and formulation. Modern applications of Tingli Dazao Xiefeitang focus primarily on the respiratory system, with pleural effusion being the most common condition. For the preparation and decoction, a single dose of 5 g of Descurainiae Semen Lepidii Semen (dried and mature seeds of Lepidium apetalum) processed as stir-fried seeds and 36 g of Jujubae Fructus (dried and mature fruit of Ziziphus jujuba) prepared as raw materials were recommended. Then 600 mL of water was added and Jujubae Fructus was first boiled until the volume reduced to 400 mL. After filtering out the residue, the supernatant was retained and mixed with stir-fried Descurainiae Semen Lepidii Semen, followed by boiling to 200 mL, which should be consumed all at once. This research provides a theoretical basis for the development and application of this formula.
