As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) in improving early enteral nutrition tolerance in patients with acute pancreatitis (AP) under the concept of accelerated rehabilitation, and to explore the related mechanism based on the changes in autonomic nerve characteristics. METHODS: A total of 42 patients with AP were randomized into an observation group (21 cases, 1 case dropped out) and a control group (21 cases, 1 case dropped out). The control group received standard basic treatment for AP. On the basis of the treatment in the control group, EA was applied in the observation group, bilateral Zusanli (ST36), Yixian point (Extra), Tianshu (ST25), Neiguan (PC6) and Zhongwan (CV12) were selected as the main points, and the supplementary points were selected according to syndrome differentiation. Ipsilateral Zusanli (ST36) and Yixian point (Extra) were connected to EA, using discontinuous wave, in frequency of 2 Hz, 30 min a time, once a day for 6 continuous days. The enteral nutrition tolerance score was observed before treatment and after 3 and 5 days of treatment; the visual analogue scale (VAS) score for abdominal pain was observed before treatment and after 3 days of treatment; the time of reaching the feeding goal and hospital stay was recorded; the levels of C-reactive protein (CRP) and amylase were measured before treatment and after 5 days of treatment; the heart rate variability (HRV) indexes (standard deviation of NN intervals [SDNN], average standard deviation of NN intervals [SDANN], root mean square of successive NN interval differences [rMSSD], low frequency [LF] and high frequency [HF], ratio of low frequency to high frequency [LF/HF]) were monitored in the two groups. RESULTS: After 3 and 5 days of treatment, the enteral nutrition tolerance scores were decreased compared with those before treatment in both groups (P<0.01), the reductions in the observation group were larger than those in the control group (P<0.01). After 3 days of treatment, the VAS scores for abdominal pain were decreased compared with those before treatment in both groups (P<0.01), the reduction in the observation group was larger than that in the control group (P<0.01). The time of reaching the feeding goal and hospital stay in the observation group was shorter than that in the control group (P<0.05). After 5 days of treatment, the CRP and amylase levels were decreased compared with those before treatment in both groups (P<0.01), the reduction of CRP level in the observation group was larger than that in the control group (P<0.01). In the observation group, SDNN, SDANN and LF/HF were lower than those in the control group (P<0.05, P<0.01), while rMSSD was higher than that in the control group (P<0.01). SDNN, SDANN and LF/HF were positively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.05), while rMSSD was negatively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.01). CONCLUSION Electroacupuncture can improve enteral nutrition tolerance in patients with AP by regulating autonomic nervous function, alleviating the inflammation, promoting accelerated recovery, and reducing the length of hospital stay.

This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

The KCNQ potassium channels play a crucial role in modulating neural excitability, and their dysfunction is closely associated with epileptic disorders. While variants in KCNQ2 have been extensively studied, KCNQ3-related disorders have rarely been reported. With advances in next-generation sequencing technologies, an increasing number of cases of KCNQ3-related disorders have been identified. However, the correlation between genotype and phenotype remains poorly understood. In this study, we established a variant library consisting of 24 missense mutations in KCNQ3 and introduced these mutations into three different template types: KCNQ3, KCNQ3-A315T (Q3*), and KCNQ3-KCNQ2 tandem (Q3-Q2). We then analyzed the effects of these mutations on the KCNQ3 channel function using patch-clamp recording. The most informative parameter across all three backgrounds was the current density of the mutant channels. The current density patterns in the Q3* and Q3-Q2 backgrounds were similar, with most mutations resulting in an almost complete loss of function (LOF), they were concentrated in the pore-forming domain of KCNQ3. In contrast, mutations in the voltage-sensing domain or C-terminus did not show significant differences from the wild-type channel. Interestingly, these LOF mutations were typically associated with self-limited familial neonatal epilepsy, while neurodevelopmental disorders (NDD) were more closely associated with mutations that did not significantly differ from the wild-type. V_1/2, another important parameter of the electrophysiological properties, could not be accurately determined in the majority of KCNQ3 mutations due to its nearly complete LOF in the Q3* and Q3-Q2 backgrounds. Intriguingly, the V_1/2 of functional mutations were primarily leftward shifted, indicating a gain-of-function (GOF) effect, which was typically associated with NDD. In addition to previously reported mutations, we identified G553R as a novel GOF mutation. In the co-transfection background, parameters such as V_1/2 could be determined, but the dysfunctional effects of these mutations were mitigated by the co-expression of wild-type KCNQ3 and KCNQ2 subunits, resulting in no significant differences between most mutations and the wild-type channel. Furthermore, we applied KCNQ modulators to reverse the electrophysiological abnormalities caused by KCNQ3 variants. The LOF mutations were reversed by the application of Pynegabine (HN37), a KCNQ opener, while the GOF mutation responded well to Amitriptyline (AMI), a KCNQ inhibitor. These findings provide essential insights into the pathogenic mechanisms underlying KCNQ3-related disorders and may inform clinical decision-making.

Objective To investigate the multi-target mechanisms of quercetin in treating endometriosis(EMT)through integrative network pharmacology analysis.Methods Active targets of quercetin were collected from the TCMSP database,while EMT-related differentially expressed genes(DEGs)were identified through the Gene Expression Omnibus(GEO)dataset.A comparative analysis was conducted to pinpoint potential therapeutic targets of quercetin for EMT treatment.Functional enrichment analyses were employed to investigate the biological functions associated with these targets,and a protein-protein interaction(PPI)network was conducted to identify core targets.Molecular docking and dynamics simulations were performed to validate the binding characteristics between quercetin and the core targets.The top 2 target protein pairs,HSP90AB1 and AR,exhibiting the lowest binding energy,were selected for subsequent cellular experimental validation.Human EMT-immortalized ectopic endometrial epithelial cell line 12Z(n=6,independent replicates)was subjected,and CCK-8 assay was used to determine ehe effects of quercetin on cell viability and proliferation,and the half-maximal inhibitory concentration(IC50)was calculated at 48 h after treatment.Then the 12Z cells were treated with quercetin at a concentration gradient of 0,30,60 and 90 μmol/L,the migration and invasion abilities were assessed with cell scratch and cell invasion assays.Western blotting was conducted to detect the changes in the expression of HSP90AB1 and AR proteins after different doses of treatment.Results There were 49 potential EMT-related therapeutic targets and 10 core targets identified.Functional enrichment analyses revealed that these targets were significant enriched in inflammation-related signaling pathways,including AGE-RAGE,ErbB and TNF;immune-related pathways,such as Th17 cell differentiation,T/B cell receptor signaling;angiogenesis-related pathways like VEGF;and hormonal regulatory pathways involving estrogen and GnRH.Molecular docking demonstrated that quercetin exhibited favorable binding activity(binding energy<-5 kcal/mol)with all core target proteins,with particularly strong binding energies(<-7 kcal/mol)observed for AR,EGFR,FOS,ERBB2,and HSP90AB1.Molecular dynamics simulations revealed that quercetin forms sustained hydrogen bond interactions with AR and HSP90AB1,facilitating the formation of stable complexes.CCK-8 assay,cell scratch assay,and transwell invasion assay indicated that quercetin inhibited the proliferative activity,and migrative and invasive abilities of 12Z cells in a concentration-dependent manner,with more pronounced inhibitory effects observed at 60 and 90 μmol/L quercetin(P<0.001);Western blotting revealed that treatment of 12Z cells with varying quercetin concentrations for 48 h up-regulated the expression of HSP90AB1 and AR,with the most significant increase observed at 90 μmol/L quercetin(HSP90AB1,P<0.05;AR,P<0.001).The restored expression levels of HSP90AB1 and AR showed positive correlations with the proliferative activity,migrative and invasive abilities of ectopic endometrial cells.Conclusion Quercetin effectively addresses endometriosis through multiple molecular targets and signaling pathways,and stabilization of the HSP90AB1/AR complex and subsequent protein upregulation represents a key therapeutic mechanism.

AIM:To investigate whether crocin alleviates right ventricular injury induced by monocrotaline(MCT)in rats with pulmonary arterial hypertension(PAH),and to explore the underlying mechanisms.METHODS:Forty male SD rats were randomly divided into 4 groups:normal group,PAH group,crocin group and sildenafil group,with 10 rats in each group.The rats in PAH,crocin and sildenafil groups received subcutaneous injection of MCT(50 mg/kg)to establish the PAH model.Starting from the day of MCT injection,the rats in crocin group received crocin(200 mg/kg),the rats in sildenafil group received sildenafil(30 mg/kg),and those in PAH and normal groups were orally gavaged with an equal volume of saline once daily.After 4 weeks,measurements of right ventricular systolic pressure(RVSP),mean pulmonary artery pressure(mPAP),right ventricular hypertrophy index(RVHI)and right ventricular mass index(RVMI)were taken for the rats in each group.Tissue staining was conducted to observe pathological changes in the right ventricle,and the expression levels of inflammatory factors(IL-1β,IL-6 and TNF-α),the p38 MAPK/NF-κB inflammato-ry pathway,CCL2,CCR2,and the macrophage marker CD68 were assessed.RESULTS:Compared with PAH group,the rats in crocin and sildenafil groups exhibited significant reductions in RVSP,mPAP,RVHI and RVMI(P＜0.05).Right ventricular tissue displayed no evident infiltration of inflammatory cells or proliferation of collagen fibers.The down-regulation of the p38 MAPK/NF-κB pathway and inflammatory factors(IL-1β,IL-6 and TNF-α)was significant(P＜0.05).Additionally,the CCL2/CCR2 pathway and the infiltration of CD68+ macrophages were markedly decreased(P＜0.05).CONCLUSION:Crocin effectively mitigates right ventricular damage in MCT-induced PAH rats,with its effica-cy comparable to that of sildenafil at the dosage utilized in this experiment.Some protective mechanisms of crocin may be attributed to its regulatory effects on inflammation.
