ObjectiveTo explore the spatial distribution patterns of flavonoid glycosides in Epimedium sagittatum and the influences of environmental factors on the accumulation of these components. MethodsThe spatial statistical analysis and GeoDetector model were used to analyze the distribution patterns of epimedin A，epimedin B，epimedin C，icariin，and total flavonoid glycosides in E. sagittatum samples from 92 different production areas in 36 cities of 13 provinces/municipalities/autonomous regions of China，as well as the effects of 28 environmental factors on the accumulation of each component. ResultsThe average content of flavonoid glycosides 64 （69.56%） producing areas and 30 （83.33%） cities met the quality standard of no less than 1.50% of total flavonoid glycosides in the 2020 edition of Chinese Pharmacopoeia.Epimedin A，epimedin B，epimedin C，icariin，and their sum showed significantly high accumulation.The hot spots regions of epimedin A and epimedin B were similar with each other，mainly located in western Hunan，eastern Hubei，eastern Guizhou，and northern Guangxi.The common hot spot areas of epimedin C and total flavonoid glycosides were in western and southwestern Hunan，southern Henan，northern Anhui，eastern Guizhou，and southern Chongqing.The hot spots areas of icariin were in southern Chongqing，western Hunan，and eastern and northeastern Guizhou.The interactions between environmental factors had stronger explanatory power for the accumulation of components than single factors.The strongest single factor and interactive factor affecting the accumulation of epimedin C were precipitation of wettest quarter （q=0.16） and its interaction with temperature seasonality （q=0.35），respectively.The strongest single factor influencing both the accumulation of icariin and total flavonoid glycosides was the precipitation of coldest quarter （q equals 0.15 and 0.22，respectively）.The strongest interactions were observed between precipitation of coldest quarter and gravel content （q=0.34），as well as between precipitation of coldest quarter and aspect （q=0.35）. ConclusionThirteen cities，including Zhumadian and Nanyang in Henan，Huaihua，Shaoyang，and Zhangjiajie in Hunan，and Zunyi，Qiandongnan，and Tongren in Guizhou，were hot spots of total flavonoid glycosides in E.sagittatum.Precipitation，gravel content，temperature seasonality，and aspect significantly influence the accumulation of flavonoid glycosides in E.sagittatum.This study provides reference for the utilization and production zoning of E.sagittatum.

ObjectiveTo study the regulatory effects of Yinchenhao Tang combined with Yinchen Zhufu Tang on the expression of regulatory T （Treg）/helper T 17 （Th17） cells cultured in vitro from the patients with hepatitis B virus-related acute-on-chronic liver failure （HBV-ACLF）. MethodsFresh peripheral blood was collected from the patients with HBV-ACLF for the separation of peripheral blood mononuclear cells （PBMCs）. Immunomagnetic beads were used to isolate primary Treg and naive CD4⁺ T cells. After in vitro expansion， naive CD4⁺ T cells were induced to differentiate into Th17 cells. Rats were treated with the clearing method （Yinchenhao Tang）， warming method （Yinchen Zhufu Tang）， and combination of clearing method with warming method （Yinchenhao Tang combined with Yinchen Zhufu Tang， also known as Wenyang Jiedu Huayu Prescription）， respectively， and then the medicated plasma samples were collected. Meanwhile， blank plasma was collected from the rats treated with normal saline. Cells were classified into blank， clearing method （5.04 g·kg^-1）， warming method （6.21 g·kg^-1）， and combination of clearing method with warming method （17.1 g·kg^-1） groups and treated with corresponding plasma. The frequency of Treg/Th17 cells was detected by flow cytometry. The level of transforming growth factor-β （TGF-β） was measured by the enzyme-linked immunosorbent assay. The cytometric bead array （CBA） was employed to measure the levels of interleukin-10 （IL-10）， interleukin-17A （IL-17A）， tumor necrosis factor-α （TNF-α）， and interleukin-23 （IL-23）. The mRNA and protein levels of Forkhead box P3 （FoxP3） and retinoic acid-related orphan receptor-gamma t （ROR-γt） were determined by Real-time PCR and Western blot， respectively. ResultsCompared with the blank group， the combination of clearing method with warming method group showed decreased frequency of Treg and Th17 cells， lowered levels of Treg cytokines （TGF-β and IL-10） and Th17 cytokines （TNF-α， IL-17A， and IL-23）， and down-regulated mRNA and protein levels of FoxP3 and ROR-γt （P<0.01）. Compared with the clearing method group， the combination of clearing method with warming method group showed decreased Treg cell frequency and down-regulated mRNA and protein levels of FoxP3. Meanwhile， the combination group showed decreased Th17 cell frequency， lowered levels of TGF-β， IL-10， TNF-α， IL-17A， and IL-23， and down-regulated mRNA and protein levels of ROR-γt （P<0.05， P<0.01）. Compared with the warming method group， the combination of clearing method with warming method group showed decreased frequency of Treg cells and down-regulated mRNA and protein levels of FoxP3. Meanwhile， the combination group showed decreased Th17 cell frequency， declined levels of TGF-β， IL-10， TNF-α， IL-17A， and IL-23， and down-regulated mRNA and protein levels of ROR-γt （P<0.05）. ConclusionThe combination of clearing method with warming method can down-regulate the expression of specific cytokines of Treg and Th17 cells， inhibit the over activation of Treg and Th17 cells， and reduce the secretion of cytokines such as TGF-β， IL-10， TNF-α， IL-17A， and IL-23， thereby alleviating inflammation and improving the prognosis of the patients with liver failure.

ObjectiveTo investigate the differential expression of intestinal flora in patients with different traditional Chinese medicine （TCM） syndrome types （Yang Huang syndrome， Yin-Yang Huang syndrome， and Yin Huang syndrome） of hepatitis B virus-related acute-on-chronic liver failure （HBV-ACLF） and clarify the biological basis of jaundice and Yin Huang syndrome in liver failure. MethodsA total of 20 cases of HBV-ACLF patients were included in the Yang Huang group， 20 cases in the Yin-Yang Huang group， 16 cases in the Yin Huang group， and 20 healthy adult volunteers. 16S rRNA gene sequencing was used to detect the diversity， species distribution， and differences of the subjects' intestinal flora， and bioinformatics analysis was conducted. ResultsCompared with those in the healthy control group， the species richness and diversity of intestinal flora in the HBV-ACLF Yang Huang group， Yin-Yang Huang group， and Yin Huang group were significantly reduced， and there were significant differences in the composition of intestinal flora compared with healthy volunteers. However， there were no significant differences in the species richness， diversity， and composition of intestinal flora among the three groups. LEfSe analysis showed that compared with the healthy control group， the HBV-ACLF Yang Huang group showed significant enrichment of Staphylococcus aureus（P<0.01）. Yin-Yang Huang group showed significant enrichment of s_Ileibacterium valens（P<0.05，P<0.01）， and the Yin Huang group showed significant enrichment of Enterococcus faecium and Streptococcus sali varius（P<0.05）. These strains may be biomarkers between the three groups of patients and the healthy control group. Compared with that in the Yin-Yang Huang group， Tyzzerella_nexilis was significantly enriched in the Yang-Huang group， and Streptococcus lactiae was significantly enriched in the Yin-Yang Huang group. Compared with that in the Yang-Huang group and the Yin-Yang Huang group， Enterococcus faecalis was significantly enriched in the Yin Huang group. The above strains may be biomarkers among the three groups of patients， and Enterococcus faecium may be a biomarker for the transition from the Yang Huang group to the Yin Huang group. ConclusionsThere are significant differences in the intestinal flora between patients with HBV-ACLF Yang Huang syndrome， Yin-Yang Huang syndrome， and Yin Huang syndrome. Enterococcus faecium is significantly enriched in the Yin Huang syndrome group， suggesting that dysbiosis of the intestinal flora may be the biological basis for jaundice and Yin Huang syndrome in liver failure.

Allergic rhinitis （AR） is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine （TCM） employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment， demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies （such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction， Yiqi tuomin decoction）， external therapies （including intradermal needles， acupoint application， tuina， and herbal nasal therapy）， as well as combined internal and external approaches （oral herbs combined with acupoint application）， have demonstrated significant effects in alleviating clinical symptoms， improving immune indicators， and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase， thereby modulating immune balance， suppressing inflammatory responses， inhibiting pyroptosis， reducing mucus secretion， and promoting nasal mucosal repair.

BACKGROUND: The sirtuin family is well recognized for its crucial involvement in various cellular processes. Nevertheless, studies on its role in the human endometrium are limited. This study aimed to explore the expression and localization of the sirtuin family in the human endometrium, focusing on sirtuin 3 (SIRT3) and its potential role in the oxidative imbalance of the endometrium in polycystic ovary syndrome (PCOS). METHODS: Endometrial specimens were collected from both patients with PCOS and controls undergoing hysteroscopy at the Center for Reproductive Medicine, Peking University Third Hospital, from July to August 2015 and used for cell culture. The protective effects of SIRT3 were investigated, and the mechanism of SIRT3 in improving endometrial receptivity of patients with PCOS was determined using various techniques, including cellular bioenergetic analysis, small interfering ribonucleic acid (siRNA) silencing, real-time quantitative polymerase chain reaction, Western blot, immunofluorescence, immunohistochemistry, and flow cytometry analysis. RESULTS: The sirtuin family was widely expressed in the human endometrium, with SIRT3 showing a significant increase in expression in patients with PCOS compared with controls ( P <0.05), as confirmed by protein and gene assays. Concurrently, endometrial antioxidant levels were elevated, while mitochondrial respiratory capacity was reduced, in patients with PCOS ( P <0.05). An endometrial oxidative stress (OS) model revealed that the downregulation of SIRT3 impaired the growth and proliferation status of endometrial cells and reduced their receptivity to day 4 mouse embryos. The results suggested that SIRT3 might be crucial in maintaining normal cellular state by regulating antioxidants, cell proliferation, and apoptosis, thereby contributing to enhanced endometrial receptivity. CONCLUSIONS Our findings proposed a significant role of SIRT3 in improving endometrial receptivity in patients with PCOS by alleviating OS and regulating the balance between cell proliferation and apoptosis. Therefore, SIRT3 could be a promising target for predicting and improving endometrial receptivity in this patient population.

Descurainiae Semen Lepidii Semen, also known as Tinglizi, originates from Brassicaceae plants Descurainia sophia or Lepidium apetalum. The former is commonly referred to as "Southern Tinglizi(Descurainiae Semen)", while the latter is known as "Northern Tinglizi(Lepidii Semen)". To scientifically and accurately identify the origin of Tinglizi medicinal materials and traditional Chinese medicine products, this study developed a specific DNA mini-barcode based on chloroplast genome sequences. By combining the DNA mini-barcode with DNA metabarcoding technology, a method for the qualitative and quantitative identification of Tinglizi medicinal materials and Chinese patent medicines was established. In this study, chloroplast genomes of Southern Tinglizi and Northern Tinglizi and seven commonly encountered counterfeit products were downloaded from the GenBank database. Suitable polymorphic regions were identified to differentiate these species, enabling the development of the DNA mini-barcode. Using DNA metabarcoding technology, medicinal material mixtures of Southern and Northern Tinglizi, as well as the most common counterfeit product, Capsella bursa-pastoris seeds, were analyzed to validate the qualitative and quantitative capabilities of the mini-barcode and determine its minimum detection limit. Additionally, the mini-barcode was applied to Chinese patent medicines containing Tinglizi to authenticate their botanical origin. The results showed that the developed mini-barcode(psbB) exhibited high accuracy and specificity, effectively distinguishing between the two authentic origins of Tinglizi and commonly encountered counterfeit products. The analysis of mixtures demonstrated that the mini-barcode had excellent qualitative and quantitative capabilities, accurately identifying the composition of Chinese medicinal materials in mixed samples with varying proportions. Furthermore, the analysis of Chinese patent medicines revealed the presence of the adulterant species(Capsella bursa-pastoris) in addition to the authentic species(Southern and Northern Tinglizi), indicating the occurrence of adulteration in commercially available Tinglizi-containing products. This study developed a method for the qualitative and quantitative identification of multi-origin Chinese medicinal materials and related products, providing a model for research on other multi-origin Chinese medicinal materials.

OBJECTIVE: To observe the clinical efficacy and safety of automatic pressure-controlled pressure cupping in patients with lumbar disc herniation, and compare it with traditional cupping. METHODS: A total of 100 patients diagnosed with lumbar disc herniation from January 2022 to August 2024 were selected and divided into two groups:the automatic pressure-controlled pressure cupping group (controlled pressure cupping group) and the traditional cupping group (control group), 50 cases in each group. In the controlled pressure cupping group, there were 18 males and 32 females, with an age of (51.98±12.69) years;in the control group, there were 16 males and 34 females, with an age of (51.32±12.05) years. The visual analogue scale(VAS), comfort score, and lumbar range of motion were observed before treatment and after the 1st, 3rd, and 7th treatments to evaluate the efficacy and safety. RESULTS: All patients completed the treatment intervention, with complete follow-up data collected. No adverse reactions or complications occurred during treatment and follow-up. After the 3rd treatment, the VAS score of the controlled pressure cupping group was (2.38±0.49), which was lower than that of the control group (2.94±0.68), with a statistically significant difference (P<0.001). In the controlled pressure cupping group, the VAS scores after the 1st, 3rd, and 7th treatments were significantly better than those before treatment (P=0.026);in the control group, the VAS scores after the 3rd and 7th treatments were better than those before treatment, but the difference was not statistically significant(P=0.182). Repeated-measures analysis of variance (ANOVA) on VAS scores at different time points in both groups showed that there were statistically significant differences in inter-group, time, and interaction effects (P<0.05). After the 1st treatment, in the controlled pressure cupping group, 0 patients felt comfortable, 42 patients (84%) felt mild discomfort, and 8 patients (16%) felt moderate discomfort;in the control group, 0 patients felt comfortable, 28 patients (56%) felt mild discomfort, and 22 patients(44%) felt moderate discomfort;the difference between the two groups was statistically significant(P=0.005). After the 3rd treatment, in the controlled pressure cupping group, 30 patients(60%) felt comfortable, 20 patients (40%) felt mild discomfort, and 0 patients felt moderate discomfort; in the control group, 9 patients (18%) felt comfortable, 41 patients (82%) felt mild discomfort, and 0 patients felt moderate discomfort;the difference between the two groups was statistically significant(P<0.001). There was no statistically significant difference in comfort between the two groups after the 7th treatment(P>0.001). There was no statistically significant difference in lumbar range of motion between the two groups before and after treatment(P>0.05);compared with before treatment, the lumbar range of motion of both groups after treatment was significantly improved, with statistically significant differences (P<0.001). CONCLUSION Automatic pressure-controlled pressure cupping can effectively relieve symptoms in patients with lumbar disc herniation, with excellent safety.

PURPOSE: Emergency resuscitative thoracotomy (ERT) is a final salvage procedure for critically injured trauma patients. Given its low success rate and ambiguous indications, its use in blunt trauma scenarios remains highly debated. Consequently, our study seeks to ascertain the overall survival rate of ERT in blunt trauma patients and determine which patients would benefit most from this procedure. METHODS: A retrospective case-control study was conducted for this research. Blunt trauma patients who underwent ERT between January 2020 and December 2023 in our trauma center were selected for analysis, with the endpoint outcome being in-hospital survival, divided into survival and non-survival groups. Inter-group comparisons were conducted using Chi-square and Fisher's exact tests, the Kruskal-Wallis test, Student's t-test, or the Mann-Whitney U test. Univariate and multivariate logistic regression analyses were conducted to assess potential predictors of survival. Then, the efficacy of the predictors was assessed through sensitivity and specificity analysis. RESULTS: A total of 33 patients were included in the study, with 4 survivors (12.12%). Multivariate logistic regression analysis indicated a significant association between cardiac tamponade and survival, with an adjusted odds ratio of 33.4 (95% CI: 1.31 - 850.00, p = 0.034). Additionally, an analysis of sensitivity and specificity, targeting cardiac tamponade as an indicator for survivor identification, showed a sensitivity rate of 75.0% and a specificity rate of 96.6%. CONCLUSION The survival rate among blunt trauma patients undergoing ERT exceeds traditional expectations, suggesting that select individuals with blunt trauma can significantly benefit from the procedure. Notably, those presenting with cardiac tamponade are identified as the subgroup most likely to derive substantial benefits from ERT.
