OBJECTIVE To establish the UPLC fingerprint and the method for multi-component content determination in Jingangteng capsules， and to evaluate its quality by combining chemical pattern recognition analysis. METHODS An UPLC method was established. Separation was performed on a Zorbax SB-C 18 Rapid Resolution HD column， with acetonitrile-0.1% formic acid as the mobile phase for gradient elution.Using the Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicines （2012 edition）， UPLC fi ngerprints were established for 10 batches of Jingangteng capsules， and similarity was evaluated. SPSS 22.0 and SIMCA 14.1 software were used to perform hierarchial-cluster analysis and orthogonal partial least squares discriminant analysis （OPLS-DA）， respectively. The same UPLC method was employed to determine the contents of chlorogenic acid， 3，5-dihydroxy-2-methylbenzoic acid-3- O -glucoside （M1）， caffeic acid， astilbin， oxyresveratrol， quercitrin and resveratrol in the 10 batches of samples. RESULTS A total of 17 common peaks were identified in UPLC fingerprints of the 10 batches of samples， of which 7 were identified as chlorogenic acid， M1， caffeic acid， astilbin， oxyresveratrol， quercitrin， and resveratrol. The similarities of 10 batches of samples ranged from 0.820 to 0.985. The results of hierarchial-cluster analysis showed that 10 batches of samples were grouped into four categories： S1-S4 formed one group， S5 and S6 formed another， S7， S8 and S10 formed a third， and S9 formed a fourth， consistent with the OPLS-DA results； the variable importance projection values for peaks 7， 10， 2， 16 （resveratrol）， 13 （oxyresveratrol）， 11， 6 （caffeic acid）， 5 （M1） and 15 （quercitrin） were ＞1. Quantitative analysis results showed that the contents of chlorogenic acid， M1， caffeic acid， astilbin， oxyresveratrol， quercitrin， and resveratrol were 1.650 8-4.213 7， 0.636 2-2.161 7， 0.031 0-0.086 5， 0.239 1-1.069 3， 0.211 9-1.104 0， 0.488 8-2.399 2， and 0.164 0-0.699 8 mg/g， respectively. CONCLUSIONS UPLC fingerprint and content determination methods established in this study are simple to operate， accurate， reliable and reproducible； when combined with chemical pattern recognition analysis， they can be used to evaluate the quality of Jingangteng capsules. Nine components， such as resveratrol， oxyresveratrol， caffeic acid， M1 and quercitrin， may serve as markers of quality variation.

Genetically modified pigs for welfare assurance is crucial for conducting xenotransplantation. However, traditional experimental animal ethics principles cannot address the social benefits issues brought about by xenotransplantation, and there is a lack of ethical justification for the assurance of experimental animal welfare. Degrazia and Bechtel proposed six principles for the welfare of experimental animals: the principle of no alternative methods, the principle of expected net benefits, the principle of adequate defense of harm, the principle of no harm without necessity, the principle of basic needs and the principle of harm limit. This paper conducts an ethical-level argumentation on the six principles for the welfare of genetically modified pigs in xenotransplantation, and points out that these six principles are of great significance in closely integrating the social benefits of xenotransplantation with the welfare of genetically modified pigs, emphasizing the moral status of genetically modified pigs, and providing standards for the ethical review of the welfare of genetically modified pigs.

OBJECTIVE To investigate the antidepressant effect and underlying mechanism of total triterpenes from Poriae Cutis （PCTT）. METHODS UPLC-Q-TOF-MS technology was adopted to analyze the chemical constituents of PCTT. Network pharmacology was applied to screen the antidepressant active ingredients， key targets and signaling pathways of PCTT， and molecular docking was performed to verify the binding capacity between potential active ingredients and core targets. In animal experiment， mice were intragastrically administered PCTT at doses of 80， 160 and 320 mg/kg for 14 consecutive days. Lipopolysaccharide was used to establish an acute depression mouse model. Subsequently， behavioral assays were conducted. The levels of serum inflammatory factors， hippocampal neurotransmitters and brain-derived neurotrophic factor （BDNF） were detected. Western blot and qPCR assays were adopted to validate the antidepressant mechanism of PCTT. RESULTS A total of 101 chemical constituents were identified in PCTT. Network pharmacology screened out 10 potential active ingredients （including poriacosone B， poriacosone A， pachymic acid， etc.）， six core targets [including tumor necrosis factor （TNF）， peroxisome proliferator-activated receptor， caspase-3， etc.]， as well as multiple signaling pathways including TNF and interleukin-17 （IL-17）. All 10 potential active ingredients exhibited strong binding affinity to the six core targets. Animal experimental results demonstrated that 320 mg/kg PCTT markedly increased the movement distance and movement speed of depression model mice （P＜0.05）， and shortened immobility time in tail suspension test and forced swimming test （P＜0.05）. PCTT reduced serum levels of IL-6， IL-1β and TNF-α， decreased hippocampal glutamate level； it also downregulated the relative mRNA expression of TNF-α， tumor necrosis factor receptor-2 （TNFR2）， phosphoinositide 3-kinase （PI3K） and protein kinase B （AKT）， as well as TNFR2 protein expression and the ratios of phosphorylated-PI3K/PI3K，phosphorylated-AKT/AKT in the prefrontal cortex. Meanwhile， PCTT elevated the levels of 5- hydroxytryptamine， dopamine and BDNF in the hippocampus. CONCLUSIONS PCTT exerts antidepressant effects possibly by regulating the TNF-α/PI3K/AKT signaling pathway to downregulate the expression of pro-inflammatory factors， thereby modulating the release of neurotransmitters and BDNF.

Lung cancer is one of the most lethal cancers, and the overall survival rate of lung cancer patients is very low. With the increasing research on lung cancer, the critical role of intestinal flora in lung cancer treatment has been gradually discovered. Among the various therapeutic approaches targeting the intestinal flora, fecal microbiota transplantation (FMT) is considered as a potential strategy to treat lung cancer by interfering with the homeostasis of the intestinal flora. FMT can improve the efficacy of lung cancer treatment and attenuate the side effects associated with immunotherapy, chemotherapy, and radiotherapy by remodeling the microbial composition, modulating the metabolites, and activating immune responses. The aim of this paper is to discuss the current status and potential mechanisms of FMT in lung cancer treatment, and to provide a new strategy for regulating the intestinal flora to enhance the prevention and treatment of lung cancer.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To investigate the efficacy of radiotherapy in patients with advanced esophageal cancer receiving first-line chemoimmunotherapy.Methods:A retrospective analysis was conducted on the data of 137 patients with Stage Ⅳ esophageal squamous cell carcinoma (ESCC) treated at our hospital from January 2018 to May 2023. These patients were divided into two groups: a group treated with first-line chemoimmunotherapy combined with radiotherapy (chemoimmunotherapy + radiotherapy group, n = 43) and a group treated with only chemoimmunotherapy ( n = 94). Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between the groups. With overall survival (OS) and progression-free survival (PFS) as study endpoints, the survival data were analyzed using the Kaplan-Meier method, the log-rank test, and the Cox regression method. Results:Before calibration, the chemoimmunotherapy + radiotherapy group significantly outperformed the sole chemoimmunotherapy group in median PFS (13.6 months vs. 7.0 months; HR: 0.501, 95% CI: 0.309-0.811, P = 0.005). After calibration using the COX proportional-hazards model for age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, smoking history, T/N/M stage, and tumor location, the chemoimmunotherapy + radiotherapy group still had significant advantages in PFS (14.7 months vs. 7.0 months; HR: 0.441, 95% CI: 0.261-0.745, P = 0.002). IPTW analysis further confirmed this trend (13.9 months vs. 7.0 months; HR: 0.492, 95% CI: 0.304-0.795, P < 0.001). Specifically, the median OS of the chemoimmunotherapy + radiotherapy group demonstrated significant improvement in all analyses: pre-calibration (29.5 months vs. 18.0 months; HR: 0.507, 95% CI: 0.297-0.867, P = 0.013), after calibration using the Cox model (27.5 months vs. 16.7 months; HR: 0.470, 95% CI: 0.266-0.830, P = 0.009), and after calibration using IPTW (29.5 months vs. 16.9 months; HR: 0.448, 95% CI: 0.262-0.764, P < 0.001). Conclusions:The combination of radiotherapy and first-line chemoimmunotherapy can significantly improve survival outcomes of patients with advanced ESCC, suggesting its potential as a standard treatment strategy.

Objective:To establish the reference intervals (RIs) of systemic immune inflammatory index (SII), platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR) and monocyte to lymphocyte ratio (MLR) in healthy pregnant women in Henan province, China.Methods:A retrospective analysis was conducted on the data of the healthy pregnant women without a history of adverse pregnancy events who participated in health check-ups from August 2016 to February 2019. A total of 4 016 healthy pregnant women were selected for establishing RIs. Data from healthy adult control group were derived from the healthy adult cohort in Henan established earlier by our team, and the Propensity Score Matching analysis was used and 3 595 healthy adult women and 3 595 healthy pregnant women to compare the indicators between the two groups. The RIs of the above indicators were established using the indirect method with a 95% confidence interval. The Tukey Rule was used to identify and remove outliers. The RIs were stratified and grouped based on the differences in each indicator during the pregnancy: SII: 3 929 cases, including 712 in the first trimester, 1 947 in the second trimester, and 1, 270 in the third trimester; PLR: 3 927 cases, no grouping; NLR: 3 925 cases, including 712 in the first trimester and 3 213 in the second and third trimesters; LMR: 3 925 cases, including 723 in the first trimester, 1 942 in the second trimester, and 1 260 in the third trimester; MLR: 3 904 cases, including 721 in the first trimester, 1 928 in the second trimester, and 1 255 in the third trimester. After the RIs were established, another 396 healthy pregnant women without a history of adverse pregnancy events who participated in health check-ups from February to April 2019 were selected for the validation of the RIs.Results:SII, NLR, LMR, MLR, and PLR differ significantly between healthy adult women and healthy pregnant women. There were significant differences in SII, LMR, and MLR among the three trimesters ( P<0.05). NLR in the first trimester was significantly lower than that in the second and third trimesters ( P<0.05), while there was no significant difference between the second and third trimester ( P=0.124). PLR only showed significant differences between the second and third trimester ( P<0.05), while no significant differences were found among the other groups. Based on the above results, the stratified RIs of each index in healthy pregnant population were established and verified. SII: first trimester (341-1 426)×10 9/L, second trimester (437-1 680)×10 9/L, third trimester (379-1 580)×10 9/L; PLR: 73-215; NLR: first trimester 1.78-5.60, second and third trimester 2.21-6.74; LMR: first trimester 2.20-6.61, second trimester 1.85-5.42, third trimester 1.63-4.82; MLR: first trimester 0.14-0.42, second trimester 0.17-0.49, third trimester 0.18-0.55. The rejection rate of 396 cases was less than 10%. Conclusions:The RIs of SII, NLR, LMR, MLR and PLR for healthy pregnant women in Hernan province of China were established and validated, and4 could be used in clinical practice.

Objective:To investigate the relationship between adiponectin (ADPN), the ratio of high-sensitivity C-reactive protein (hs-CRP) to albumin (ALB), and the progression of acute cerebral infarction (ACI).Methods:This case-control study involved 147 patients with ACI who were treated at Xingyuan Hospital of Yulin between January 2023 and March 2024. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate disease progression. Based on the progression of the disease, the patients were divided into two groups: the progressive group ( n = 38) and the non-progressive group ( n = 109). ADPN level and the hs-CRP/ALB ratio were compared between the two groups. Additionally, multivariate logistic regression analysis was conducted to identify risk factors for disease progression in ACI patients. The predictive value of ADPN and the hs-CRP/ALB ratio for ACI was assessed using receiver operating characteristic curve analysis. Results:In the progressive group, hs-CRP level and hs-CRP/ALB ratio were (14.38 ± 3.27) mg/L and (0.43 ± 0.13), respectively, both of which were significantly higher than those in the non-progressive group [(8.92 ± 2.73) mg/L, (0.20 ± 0.07), t = 9.22, 10.37, both P < 0.001]. In contrast, the levels of ADPN and albumin in the progressive group were (2.71 ± 0.59) mg/L and (33.54 ± 8.66) g/L, respectively, both of which were significantly lower than those in the non-progressive group [(5.36 ± 1.42) mg/L, (45.05 ± 10.42) g/L, t = -15.99, -6.68, both P < 0.001]. The progressive group had higher admission NIHSS scores, a higher proportion of patients with diabetes, higher white blood cell counts, higher hemoglobin A1c (HbA1c) and fibrinogen levels compared with the non-progressive group ( t = 8.43, 2.88, 5.79, 2.77, χ2 = 4.40, all P < 0.05). Multivariate logistic regression analysis results indicated that higher admission NIHSS scores, HbA1c levels, and hs-CRP/ALB ratios were independent risk factors for disease progression in ACI patients ( OR = 2.438, 1.600, 2.971, all P < 0.05), while higher levels of ADPN were identified as a protective factor against disease progression ( OR = 0.321, P < 0.05). The receiver operating characteristic curve analysis showed that the area under the curve for predicting disease progression after admission for ACI patients using serum ADPN and hs-CRP/ALB ratio alone were 0.730 (95% CI: 0.658-0.800) and 0.758 (95% CI: 0.685-0.826), respectively. The area under the curve for the combined prediction of serum ADPN and the hs-CRP/ALB ratio was 0.895 (95% CI: 0.845-0.940), demonstrating higher predictive efficacy ( Z = 1.80, 2.13, both P < 0.05). Conclusions:ADPN level and hs-CRP/ALB ratio are closely related to the progression of ACI and demonstrate good predictive efficacy for disease progression.

Objective:To construct a management model of data mining for medical imaging equipment,so as to improve the quality of managing equipment.Methods:A management model of mining data was constructed to manage medical imaging equipment.A total of twenty imaging equipment that were using at Hainan Hospital of the General Hospital of the People's Liberation Army of China from April 2022 to March 2024 were selected.According to different management methods,the conventional management was adopted to manage them during April 2022 to March 2023,and the management model of mining data(model management)was adopted to manage them during April 2023 to March 2024.A self-developed questionnaire was used to conduct a satisfaction survey for imaging physicians,staffs of operating and maintaining equipment,and technicians who using and managing equipment,and patients who received diagnosis and treatment by using equipment.The failure rate and the imaging effect of equipment,the satisfaction scores of the relative staffs who used equipment,and the growth amplitude of operational benefits of equipment between two management methods were compared.Results:A total of 20 failures occurred in imaging equipment that adopted model management.In them,the failure rates of the self-equipment,improper operation and insufficient professional level were respectively 15%,5%and 5%,all of which were lower than those of the conventional management method.The predicted failure rate of model management was 75%,which was higher than that of the conventional management method,and the differences of the above indicators between two methods were statistically significant(x2=6.547,4.392,5.124,6.701,P<0.05).The scores of image clarity,qualification rate,excellent rate,qualification rate of body position,and the total score of imaging effect of adopting model management method were respectively(22.36±2.01),(23.21±1.54),(22.65±1.87),(23.21±1.52)and(91.43±6.77)points,all of which were higher than those of the conventional management method,and the differences were statistically significant(t=10.662,12.727,15.324,16.333,13.742,P<0.05).The satisfaction scores of imaging physicians,staffs of operation and maintenance,technicians and patients who uses management for adopting the model management method were all higher than those of the conventional management method,and the differences were statistically significant(t=13.586,14.249,17.021,11.006,P<0.05).The average values of growth amplitude of cost and benefit of equipment operation of adopting model management method were higher than those of the conventional management method,and the average value of the growth amplitude of the cost of the troubleshooting of model management method was lower than that of the conventional management method,and the differences of them were statistically significant(t=15.057,19.310,18.336,P<0.05).Conclusion:The application of the management model of data mining for medical imaging equipment can provide warning of equipment failures in advance,and reduce the failure rate of equipment,and improve the quality of management and operation of equipment,and enhance the service level of equipment.
