Following the core outcome set standards for development(COS-STAD), this study aims to construct core outcome set(COS) for clinical research on traditional Chinese medicine(TCM) treatment of simple obesity. Firstly, a comprehensive review was conducted on the randomized controlled trial(RCT) and systematic review(SR) about TCM treatment of simple obesity that were published in Chinese and English databases to collect reported outcomes. Additional outcomes were obtained through semi-structured interviews with patients and open-ended questionnaire surveys for clinicians. All the collected outcomes were then merged and organized as an initial outcome pool, and then a preliminary list of outcomes was formed after discussion by the working group. Subsequently, two rounds of Delphi surveys were conducted with clinicians, methodology experts, and patients to score the importance of outcomes in the list. Finally, a consensus meeting was held to establish the COS for clinical research on TCM treatment of simple obesity. A total of 221 RCTs and 12 SRs were included, and after integration of supplementary outcomes, an initial outcome pool of 141 outcomes were formed. Following discussions in the steering advisory group meeting, a preliminary list of 33 outcomes was finalized, encompassing 9 domains. Through two rounds of Delphi surveys and a consensus meeting, the final COS for clinical research on TCM treatment of simple obesity was determined to include 8 outcomes: TCM symptom scores, body mass index(BMI), waist-hip ratio, waist circumference, visceral fat index, body fat rate, quality of life, and safety, which were classified into 4 domains: TCM-related outcomes, anthropometric measurements, quality of life, and safety. This study has preliminarily established a COS for clinical research on TCM treatment of simple obesity. It helps reduce the heterogeneity in the selection and reporting of outcomes in similar clinical studies, thereby improving the comparability of research results and the feasibility of meta-analysis and providing higher-level evidence support for clinical practice.

Objective: To establish an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method based on solid-phase extraction column purification for simultaneous determination of cyromazine and melamine in poultry eggs and meat. Methods: Eggs, quail eggs, and chicken were collected from markets. After homogenization, the sample was extracted with 0.5% formic acid in acetonitrile, subjected to solid-phase extraction using an MCX cartridge, and eluted with 5% ammonia in methanol. The eluate was collected, evaporated to near dryness under nitrogen, and reconstituted in a 10% aqueous methanol solution. Separated using TSK gel Amide-80 column (2.0 mm×150 mm, 5 μm), cyromazine and melamine were simultaneously detected in positive ion multiple reaction monitoring mode via tandem mass spectrometry, with quantification achieved by isotope dilution internal standard methods. Efficiency was enhanced and matrix interference minimized by optimizing conditions such as sample extraction, solid-phase extraction cartridge selection, and instrumental parameters. Calibration curves were constructed, and detection limits, quantification limits, spiked recoveries, and relative standard deviations for (RSD) of cyromazine and melamine were calculated. Results: After method optimization, matrix effects for cyromazine and melamine ranged from 0.97 to 1.04, indicating no significant matrix suppression or enhancement. Both cyromazine and melamine exhibited excellent linearity within the concentration range of 1.0-200.0 ng/mL, with correlation coefficients ≥0.999 5. The limits of detection were 0.3 μg/kg for cyromazine and 0.5 μg/kg for melamine, the quantification limits were 1.0 and 1.5 μg/kg, respectively. At spiked levels of 1.0, 20.0, and 150.0 μg/kg, the average recoveries ranged from 78.6% to 103.1%, with RSD between 3.5% and 6.3%. Among 95 samples tested, cyromazine was detected in 6 samples and melamine in 5 samples; neither cyromazine nor melamine was detected in chicken samples. Conclusion The UPLC-MS/MS method established in this study enables simultaneous detection and accurate quantification of cyromazine and melamine in poultry eggs and meat.

OBJECTIVE: To observe the clinical effect of needle cauterization on vitiligo with deficiency cold and blood stasis. METHODS: A total of 62 patients of vitiligo with deficiency cold and blood stasis were randomly divided into an observation group and a control group, 31 cases each group.On the basis of 308 nm excimer light irradiation combined with ironing with Chinese medicine, the control group was treated with tacrolimus ointment for external use, twice a day; the observation group was treated with needle cauterization at vitiligo spots, once a week.Both groups were treated for 10 weeks. Before and after treatment, the area of vitiligo spot, TCM syndrome score, serum levels of inflammatory indexes (interleukin[IL]-6 and IL-17) were observed in the two groups, and the clinical effect was evaluated. RESULTS: After treatment, the areas of vitiligo spot, TCM syndrome scores and serum levels of IL-6, IL-17 were decreased compared with those before treatment in both groups (P<0.05), and the above indexes in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 93.5% (29/31), which was higher than 77.4% (24/31) in the control group (P<0.05). CONCLUSION Needle cauterization could reduce the areas of vitiligo spot in patients of vitiligo with deficiency cold and blood stasis, improve the clinical symptoms, its mechanism may be related to the reduction of serum levels of inflammatory indexes.

This report describes two cases of severe immune-mediated thrombocytopenia after allogeneic hematopoietic stem cell transplantation (HSCT) who were treated with umbilical cord mesenchymal stem cells (UC-MSCs). Case 1 was a child with severe aplastic anemia who underwent haploidentical bone marrow and peripheral blood HSCT, with a chimerism rate of 99.8% on day +25 and severe immune-mediated thrombocytopenia on day +60. After intravenous immunoglobulin (IVIG) pulse therapy, platelet count increased temporarily but then decreased, while cyclosporine, methylprednisolone, and rituximab had a poor therapeutic effect. Case 2 was a child with Gaucher's disease who underwent unrelated umbilical cord blood HSCT, with a chimerism rate of 96.35% on day +41 and severe immune-mediated thrombocytopenia on day +153. After three sessions of IVIG pulse therapy, the platelet count increased initially but subsequently decreased. Therapies with dexamethasone, prednisone, cyclosporine, and recombinant human thrombopoietin also yielded a poor response. Both children received three sessions of UC-MSCs infusion, and platelet counts increased and were subsequently maintained within the normal range. Case 1 has been followed up for 10 years and remains in disease-free survival. UC-MSCs infusion may be effective for severe immune-mediated thrombocytopenia that is unresponsive to first- and second-line therapies after HSCT and could potentially improve the quality of life and disease-free survival rate.

Objective To establish a stable,reliable,and clinically relevant porcine model of endotoxin-induced acute respiratory distress syndrome(ARDS).Methods Ten 8-month-old male Bama minipigs were deeply sedated,followed by invasive mechanical ventilation and electrocardiographic monitoring.Lipopolysaccharide(LPS)was intravenously pumped at 600 μg/(kg·h)for 3 hours,then maintained at 15 μg/(kg·h)thereafter.Dynamic monitoring was performed at five time points after LPS injection(LPS 0,1,3,5,and 8 h),including arterial blood gas analysis and chest computed tomography(CT)scans.Pathological examination of lung tissues obtained via bronchoscopic biopsy(HE staining and transmission electron microscopy)was conducted.These indicators were comprehensively used to evaluate the success of the animal model.Results At 5 hours after LPS administration,8 minipigs developed symptoms such as skin cyanosis,elevated body temperature,and respiratory distress.The oxygenation index decreased to<300 mmHg.Chest CT scans showed diffuse pulmonary infiltrates.Histopathology revealed alveolar edema and hyaline membrane formation.Transmission electron microscopy demonstrated disruption of pulmonary blood-air barrier,depletion of lamellar bodies in type Ⅱ pneumocytes,inflammatory cell infiltration,and exudation of plasma proteins and fibrin.Compared with LPS 0 h,at LPS 8 h,the oxygenation index and arterial blood pH were significantly decreased(P<0.001),while blood lactic acid and serum potassium were significantly increased(P<0.05);serum calcium and base excess were significantly decreased(P<0.05),and the lung injury score based on HE-stained lung sections was significantly increased(P<0.01).Conclusion The porcine ARDS model established by continuous LPS injection can dynamically simulate the pathophysiological characteristics and typical pathological manifestations of clinical septic ARDS,making it an effective tool to study the pathogenesis,prevention,and treatment strategies of septic ARDS.

This review thoroughly investigates the application and advancements of artificial intelligence (AI) technology in the comprehensive management of lung cancer. AI is utilized at various stages of lung cancer diagnosis and treatment through techniques such as computer vision, deep learning, and natural language processing. In the early diagnosis stage, AI assists in identifying high-risk populations and, in conjunction with pathological techniques, accomplishes functions like histological classification of lung cancer tissues, prediction of molecular markers, and quantitative analysis of immunohistochemistry. During the treatment stage, AI integrates multimodal data to aid in formulating individualized treatment plans and enhances efficiency via clinical decision support systems (CDSS). In the follow-up stage, continuous patient monitoring and optimization of follow-up strategies are realized through imaging, remote monitoring, and intelligent follow-up systems. The prospects for AI medical technology are promising. However, it still confronts challenges such as weak generalizability, poor interpretability of AI decisions, and ethical and legal issues.

Objective:To analyze the distribution pattern of TCM syndrome elements in elderly patients with sepsis and septic shock, as well as the relationship between TCM syndrome elements, Sepsis Sequential Organ Failure Score (SOFA), Acute Physiology and Chronic Health Score Ⅱ (APACHE Ⅱ), and short-term mortality prognosis.Methods:A retrospective analysis was conducted on the clinical data of 58 patients treated in the Emergency Department and ICU of Dongzhimen Hospital of Beijing University of Chinese Medicine and the Third Affiliated Hospital of Beijing University of Chinese Medicine from January 1, 2021, to May 1, 2022. The patients were divided into a sepsis group of 38 cases and a septic shock group of 20 cases based on disease type. Basic information, TCM syndromes, SOFA score, and APACHE Ⅱ score of the two groups were collected. The survival and death statuses of the two groups within 28 days of admission were separately analyzed. Association rule analysis was used to investigate the distribution pattern of TCM syndromes in patients, and logistic regression analysis was performed to explore the relationship between TCM syndromes, SOFA score, APACHE Ⅱ score, and death prognosis.Results:In the sepsis group, the main TCM syndromes included yin deficiency, lung, phlegm, qi deficiency, blood stasis, heat, and yang deficiency; while in the septic shock group, the main TCM syndromes were yin deficiency, lung, yang deficiency, and qi deficiency. Multifactor logistic regression analysis showed that in the sepsis group, liver syndromes [ OR (95% CI)=0.080 (0.011, 0.578), P=0.012], meridians and collaterals [ OR (95% CI)=0.088 (0.011, 0.718), P=0.024], SOFA score [ OR (95% CI)=0.524 (0.310, 0.886), P=0.016], and APACHE Ⅱ score [ OR (95% CI)=0.426 (0.186, 0.977), P=0.044] were independent influencing factors for patient mortality prognosis. In the septic shock group, phlegm [ OR (95% CI)=0.014 (0.001, 0.267), P=0.005], meridians and collaterals [ OR (95% CI)=0.041 (0.003, 0.618), P=0.021], yang deficiency [ OR (95% CI)=0.028 (0.002, 0.427), P=0.010], SOFA score [ OR (95% CI)=0.543 (0.310, 0.950), P=0.032], and APACHE Ⅱ score [ OR (95% CI)=0.633 (0.408, 0.985), P=0.042] were independent influencing factors for patient mortality prognosis. Conclusions:The sepsis group mainly exhibits a mixture of deficiency and excess, while the septic shock group predominantly shows deficiency. Qi deficiency and yin deficiency are consistent throughout the disease progression. Meridians and collaterals, high SOFA score, and high APACHE Ⅱ score in elderly patients with sepsis and septic shock may indicate a poorer prognosis.

AIM To investigate the effects of Zuogui Jiangtang Tongmai Recipe on necroptosis pathway in a rat model of type 2 diabetes mellitus(T2DM)complicated with cerebral infarction(CI).METHODS The SD rats were randomly divided into the sham operation group,the model group,the metformin group(0.045 g/kg),and the low,medium and high dose Zuogui Jiangtang Tongmai Recipe groups(6.5,13,26 g/kg),with 9 rats in each group.In contrast to rats of the sham operation group,rats of the other groups were given 4 weeks feeding of high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin to establish a T2DM rat model with one week stable blood glucose,followed by gavage of corresponding drugs 3 days before the establishment of the middle cerebral artery occlusion(MCAO)model.After 7 days of administration,the rats had their CI injury assessed by mNSS method and TTC staining;their level of blood glucose detected by blood glucose meter;their levels of glycated serum protein,serum TNF-α and IL-1β detected by ELISA;their cerebral mRNA expressions of FADD,RIPK1,RIPK3 and MLKL detected by RT-qPCR;and their cerebral protein expressions of FADD,p-RIPK1,p-RIPK3 and p-MLKL detected by Western blot.RESULTS Compared with the sham operation group,the model group displayed increased levels of blood glucose value,glycosylated serum protein,neurological function score,cerebral infarction volume,cerebral FADD,RIPK1,RIPK3 and MLKL mRNA expressions,cerebral FADD,p-RIPK1,p-RIPK3 and p-MLKL protein expressions,serum TNF-α and IL-1β levels(P＜0.01);and more disordered and morphologically diverse neurons with smaller nucleus.Compared with the model group,the groups intervened with medium or high dose Zuogui Jiangtang Tongmai Recipe,or metformin shared improvement in terms of the aforementioned indices(P＜0.05,P＜0.01);and more neurons with regular morphology neat arrangement,and reduced cell gap.CONCLUSION Zuogui Jiangtang Tongmai Recipe can improve the neurological dysfunction of the rat model of T2DM complicated with CI,which may associate with the inhibited activation of necroptosis signaling pathway.
