ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine （TCM） in clinical practice， but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad， which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix， the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison， use of poison， anti-poison， and detoxification'' were employed to mine the relevant toxicity records， usage and dosage， processing compatibility， and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included， suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity， and the adverse reactions may be related to long-term use， excessive use， and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling， steaming with black beans， and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria， Psoraleae Fructus， and Cistanches Herba. ConclusionReasonable dosage， standard processing， correct compatibility， and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically， the toxicity classification of TCM should be strengthened， and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved， and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

Objective To study the correlation between Periostin, interleukin-33 (IL-33), and chronic cough after thoracoscopic lobectomy in patients with coronary artery bypass grafting (CABG) combined with lung cancer. Methods A total of 102 lung cancer and coronary heart disease patients at Tianjin Chest Hospital from January 2022 to January 2024 were prospectively enrolled, and they were divided into a chronic cough group (n=42) and a non-chronic cough group (n=60) based on whether chronic cough occurred after surgery. Serum levels of Periostin and IL-33 were measured on the 1st, 7th, and 14th days post-lobectomy. The Pearson method was employed to analyze the correlation between Periostin and IL-33 levels and the severity of cough. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the occurrence of chronic cough. Additionally, receiver operating characteristic (ROC) curve analysis was utilized to assess the potential value of serum Periostin and IL-33 levels in predicting postoperative chronic cough. Results In patients with chronic cough, the peripheral blood Periostin and IL-33 levels measured on days 7 and 14 were significantly higher than those in patients with non-chronic cough, and the interactions between the two groups and at different time points were significant (P<0.001). The degree of cough was positively correlated with the levels of Periostin and IL-33 on days 7 and 14 (P<0.05), but had no significant correlation with the levels on day 1 (P>0.05). In patients with lung cancer, after thoracoscopic lobectomy, Periostin [OR=1.619, 95%CI (1.295, 2.025)] and IL-33 [OR=1.831, 95%CI (1.216, 2.758)] on day 7 and Periostin [OR=1.952, 95%CI (1.306, 2.918)] and IL-33 [OR=1.742, 95%CI (1.166, 2.603)] on day 14 were identified as risk factors for chronic cough. ROC curve analysis showed that the sensitivity of Periostin on day 7 was 69.05%, the specificity was 71.67%, and the area under the curve (AUC) was 0.756 [95%CI (0.616, 0.893)]. The sensitivity of Periostin on day 14 increased to 71.43% and the specificity was 76.67%, AUC was 0.762 [95%CI (0.633, 0.898)]. At the same time, the critical value of IL-33 on day 7 was 45.03 pg/mL, the sensitivity and specificity were both 83.33%, the AUC was 0.884 [95%CI (0.789, 0.980)], and the critical value of IL-33 on day 14 was 56.01 pg/mL, the sensitivity was 85.71%, the specificity was 80.00%, and the AUC was 0.899 [95%CI (0.799, 0.999)]. Joint logistic regression analysis of Periostin and IL-33 levels on days 7 and 14 showed showed that the sensitivity was 95.24%, the specificity was 95.00%, and the AUC reached 0.993 [95%CI (0.979, 1.000)]. Conclusion Periostin and IL-33 levels, measured at various time points, are abnormally elevated following thoracoscopic lobectomy in patients with combined CABG and lung cancer. These levels significantly correlate with cough severity. Given their predictive potential for chronic cough, these markers are deemed valuable biomarkers.

The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution.

Objective:To screen the independent influencing factors of restoration of spontaneous circulation (ROSC) in patients after cardiopulmonary resuscitation (CPR) and establish a predictive model, and explore its clinical value.Methods:A retrospective case control study was conducted. The clinical data of cardiac arrest patients admitted to the emergency department of Tangdu Hospital of Air Force Military Medical University and received CPR from January to July 2023 were analyzed, including general information, blood biochemical indicators, main cause of cardiac arrest, whether it was defibrillation rhythm, duration from admission to CPR, and whether ROSC was achieved. The clinical data between the patients whether achieved ROSC or not were compared. The binary multivariate Logistic regression analysis was used to screen the independent influencing factors of ROSC in in-hospital CPR patients. According to the above influencing factors, the ROSC prediction model was established, and the receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of the model for ROSC.Results:A total of 235 patients who received CPR in the emergency department were enrolled, including 153 cases (65.11%) of in-hospital CPR and 82 cases (34.89%) of out-of-hospital CPR. The ROSC ratio was 30.21% (71/235). Among all patients, the majority were aged 61-80 years [40.43% (95/235)], and cardiogenic disease was the main cause of cardiac arrest [32.77% (77/235)]. Among 153 patients with in-hospital CPR, 89 were non-ROSC and 64 were ROSC with ROSC rate of 41.83%. Compared with the non-ROSC group, the patients in the ROSC group had lower blood lactic acid (Lac), N-terminal pro-brain natriuretic peptide (NT-proBNP), Lac/albumin (Alb) ratio (LAR), and ratio of non-defibrillation rhythm [Lac (mmol/L): 5.50 (2.33, 9.65) vs. 7.10 (3.50, 13.35), NT-proBNP (μg/L): 0.87 (0.20, 8.68) vs. 3.00 (0.58, 20.17), LAR: 0.14 (0.07, 0.29) vs. 0.19 (0.10, 0.43), non-defibrillation rhythm ratio: 68.75% (44/64) vs. 93.26% (83/89)], higher actual base excess (ABE) and Alb [ABE (mmol/L): -3.95 (-12.75, 0.23) vs. -7.50 (-13.50, -3.35), Alb (g/L): 38.13±7.03 vs. 34.09±7.81], and shorter duration from admission to CPR [hours: 3.25 (1.00, 14.00) vs. 8.00 (2.00, 27.50)], the differences were statistically significant (all P < 0.05). Binary multivariate Logistic regression analysis showed that LAR [odds ratio ( OR) = 0.037, 95% confidence interval (95% CI) was 0.005-0.287], non-defibrillation rhythm ( OR = 0.145, 95% CI was 0.049-0.426), and duration from admission to CPR ( OR = 0.984, 95% CI was 0.972-0.997) were independent influencing factors for ROSC in hospitalized CPR patients (all P < 0.05). Based on the above influencing factors, a ROSC prediction model was constructed through regression analysis results. The ROC curve analysis showed that the area under the ROC curve (AUC) for predicting ROSC in in-hospital CPR patients was 0.757 (95% CI was 0.680-0.834), Yoden index was 0.429, sensitivity was 76.6%, and specificity was 66.3%. Conclusions:LAR, non-defibrillation rhythm and duration from admission to CPR were independent influencing factors for ROSC in patients with in-hospital CPR. The ROSC prediction model established based on the above influencing factors has a good predictive value for ROSC of CPR patients in hospital, and can guide clinicians to evaluate the prognosis of patients through relevant indicators as early as possible.

Purpose The purpose of this study was to in-vestigate programmed death ligand-1(PD-L1)expression in gastric adenocarcinoma(GAC)patients and the consistency of immunohistochemical(IHC)detection of four different clones of PD-L1 antibodies,so as to provide reference for the gradual standardization of PD-L1 IHC detection in gastric adenocarcino-ma and subsequent clinical studies.Methods This study col-lected surgically resected and pathologically confirmed specimens from 286 gastric adenocarcinoma patients,and specimens were stained with four antibodies:PD-L1 22C3,SP263,E1L3N and SP142.The consistency of the antibodies was statistically ana-lyzed under different critical values using two scoring criteria:comprehensive positive score(CPS)and tumor proportion score(TPS).Results Regardless of the TPS and CPS cut-off val-ues,the positive rate of 22C3 was the highest among the four an-tibodies.Consistency analysis showed that E1L3N had good con-sistency with SP142(κ=0.612)and SP263(κ=0.660)only when the cut-off value of CPS positive was 1.In addition,the consistency between the other antibodies was only moderate or poor.Conclusion The four PD-L1 antibodies exhibited incon-sistent concordance across various TPS and CPS positive thresh-olds,so it is not recommended to exchange reagents during clini-cal testing of GAC and the test results shall be documented in accordance with the specification.

Objective To observe the effects of"Sleep Recipe"on the behavior,brain tissue and central neurotransmitters of insomnia rats.Methods The male rats with SD were randomly divided into control group,model group,sleep formula group,and eszolam group,with 10 rats in each group,and the insomnia model was constructed by intraperitoneal injection of P-chlorphenylalanine(PCPA).After successful modeling,the control group and the model group were given saline gavage,and the medylom group and eszolam group were given drug gavage.The insomnia-like behavior of rats in each group was evaluated by pentobarbital sodium correction experiment and open field experiment,Hematoxlin and eosin(HE)staining observed the pathological changes of rat cerebral cortex,hippocampus,and hypothalamic tissue,and Enzyme-linked mmunosorbent assay(ELISA)was used to determine the expression levels of Gamma-aminobutyric acid(GABA),5-hydroxytryptamine(5-HT).Results The sleep latency of rats in the model group was significantly elongated(P<0.01),while the sleep time was less(P<0.01),and the mental state and fur color were poor,significantly decreased in body weight(P<0.01).Compared with the model group,the sleep latency was significantly shortened(P<0.01),the sleep duration was significantly prolonged(P<0.01),and the body mass was significantly increased(P<0.05,P<0.01);In the open field experiment,the total activity distance of rats in the model group increased,the average speed and central region residence time decreased(P<0.05),the total activity distance of rats in the Sleep Formula group and Eszolam group decreased significantly(P<0.05),the average speed increased and the central region residence time increased(P<0.05).HE results showed that the number of neurons,morphological structure and arrangement of neurons,such as cerebral cortex,hippocampus and hypothalamus in the model group,were damaged to varying degrees,and the sleep formula group and estazolam group were significantly improved.ELISA results showed that the expression of 5-HT and GABA in the cerebral cortex and hypothalamus of rats in the model group was significantly reduced(P<0.01,P<0.05),and the expression of GABA in hippocampal tissues was also significantly reduced(P<0.01).The protein expression levels of cerebral cortical GABA,hypothalamic GABA and 5-HT in the Sleep Formula group were significantly increased(P<0.01).Conclusion Sleep Formula can improve the mental state,restore normal body weight,improve sleep efficiency,and reduce anxiety and tension in insomnia rats.The mechanism may be related to increasing the content of 5-HT and GABA,and inhibiting the spread and conduction of hypothalamic and brainstem pro-awakening nuclei.

Objective To explore the clinical efficacy and safety of one-stage posterior lesion removal and internal spinal fixation in patients with lumbar Brucellosis spondylitis.Methods The clinical data of 24 patients admitted from October 2017 to October 2022 were retrospectively analyzed,2 patients were lost to follow-up at 10 months after surgery,at the final 22 cases were included in the study,including 13 males and 9 females with an average age of(52.00±6.89)years old,were treated with one-stage posterior lesion removal and internal spinal fixation.The operation time,intraoperative bleeding,follow-up time,ery-throcyte sedimentation rate(ESR)and C-reactive protein(CRP)before and after operation were recorded.The pain visual ana-logue scale(VAS),Oswestry disability index(ODI),the Japanese Orthopaedic Association(JOA)score for neurofunction,American Spinal Injury Association(ASIA)spinal cord injury grade and modified MacNab criteria were ussed to evaluate the efficacy.Results All patients were followed up from 12 to 30 months with an average of(17.41±4.45)months.The operation time was 70 to 155 min with an average of(1 16.59±24.32)min;the intraoperative bleeding volume was 120 to 520 ml with an average of(275.00±97.53)ml.CRP and ESR levels decreased more significantly at 1 week and at the final follow-up than pre-operative levels(P＜0.05).VAS,JOA score and ODI at 1 week and at the latest follow-up were more significantly improved than preoperative results(P＜0.05).There was no significant difference between ASIA preoperative and 1 week after operation(P＞0.05),and a significant difference between preoperative and last follow-up(P＜0.05).In the final follow-up,21 patients had ex-cellent efficacy,1 patient had fair,and there was no recurrence during the follow-up.Conclusion One-stage transpedicular le-sion removal and internal spinal fixation,with few incisions and short operation time,helps the recovery of neurological func-tion,and the prognosis meets the clinical requirements,which can effectively control Brucella spondylitis.

Objective:To analyze the early warning value of laboratory examination on admission of patients with hemorrhagic fever with renal syndrome to critically ill patients.Meetods:In this study, a retrospective case-control study was used to analyze the clinical data and laboratory examination results of patients with hemorrhagic fever with renal syndrome admitted to the emergency department of Tangdu Hospital of Air Force Medical University from January 2021 to January 2022. According to the patient's laboratory indexes and clinical symptoms, the patients were divided into mild, moderate, severe and critical groups. The general data of the two groups were compared, and the independent risk factors of critically ill patients were screened by multi-factor logistic regression analysis, the predictive model of severe HFRS patients was constructed, and the ROC curve was drawn. .Results:Of the 164 patients with HFRS, 50 were in the severe group and 114 in the mild group. The serum levels of WBC, AST, ALT, Cr, BUN, DD and PCT in the severe group were higher than those in the mild group, while the levels of PLT, ALB and PTA in the severe group were lower than those in the mild group. Multiple logistic regression analysis showed that WBC, PLT and PCT were independent influencing factors for the progression of critically ill patients. The predictive model of severe HFRS was established as follows: logit (P) = -0.321 + 0.040 WBC (×10 9/L) -0.045 PLT (×10 9/L) + 0.086 PCT(ng/mL). The early warning ef?cacy of WBC, PLT, And PCT for severe HFRS was further analyzed. The area under the ROC curve (area under curve, AUC) was 0.779, 0.842, 0.862, and the optimal threshold was 10.435×109/L, 41.5 ×109/Land 2.97 ng/mL, respectively. The AUC of joint detection is 0.900, the sensitivity is 88.0%, and the speci?city is 82.5%, which is better than that of a single laboratory. . Conclusions:HFRS laboratory indexes have certain clinical signi?cance for the identi?cation of critically ill patients, in which serum WBC, PLT and PCT indexes are the risk factors of severe HFRS, which provides a theoretical basis for clinical diagnosis, treatment and prognosis of severe HFRS patients.
