In this paper， the name， origin， producing area， harvesting， processing and functional indications of Arcae Concha were systematically combed and verified by consulting the ancient and modern literature， in order to provide a basis for the development of famous classical formulas containing Arcae Concha. Arcae Concha was first recorded in the name of Han in Bencao Shiyi， but later， due to the influence of LI Shizhen's error of combining Han item with Kuiha in the Ming dynasty， there were aliases such as Kuilu and Fulao， and Yizong Bidu began to include Walengzi as its correct name and has been used ever since. The textual descriptions and illustrations of the medicinal materials of Arcae Concha contained in the materia medica of the past generations were consistent with the modern Arca inflata， A. subcrenata and A. granosa. In ancient times， there were medicinal records of two parts of shell and meat， but now the shell is used as medicine， and the meat is mostly edible. In ancient times， Zhejiang， Shandong， Guangdong and Guangxi were the main producing areas， and Zhejiang was the best. It is now believed that A. inflata is mostly distributed in the northern part of the Huanghai Sea， A. granosa is mostly distributed in the coastal areas south of Shandong Peninsula in China， and A. subcrenata is widely distributed in the coastal areas of China. Its quality is better in a complete， white， no residual meat and sand. In ancient times， there was no clear harvesting period， and the processing was mainly based on vinegar quenching after calcination or powdering of calcined shell， but now the harvesting period is autumn and winter. After harvesting， it is directly washed and crushed for raw use or processed by calcined method. The records of the medicinal materials in the past dynasties on the properties of Arcae Concha were mainly warm， sweet， salty and mild， and it is now believed that Arcae Concha is salty in taste and mild in nature. In ancient times， it was believed that Arcae Concha were mainly used for coldness in the heart and abdomen， coldness in the waist and spine， benefiting the five internal organs， strengthening the stomach. Nowadays， it is believed that Arcae Concha can eliminate phlegm and remove blood stasis， soften the hardness and dissipate the lumps， produce acid and relieve pain. It can be used in the treatment of stubborn phlegm， gall tumor， scrofula and other symptoms. In conclusion， it is suggested that for the famous classical formulas containing Arcae Concha， the corresponding methods should be selected according to the processing requirements of the drug in the formulas， while those without processing requirements can be determined according to the functional position of the products.

ObjectiveTo investigate the mechanism of action of modified Shaofu Zhuyutang in antagonizing cellular pyroptosis and fibrosis in ectopic endometrial tissues of endometriosis through the Toll-like receptor 4/nuclear factor-κB/NOD-like receptor protein 3 （TRL4/NF-κB/NLPR3） signaling pathway. MethodsSeventy-two SPF-grade female SD rats were randomly divided into a sham-operated group （n = 12） and a modeling group （n = 60）. The rats in the sham-operated group underwent a caesarean section， while the rats in the modeling group were used to establish an endometriosis model through the auto-transplantation method. After successful modeling， the animals were randomly divided into the model group， progesterone group （0.25 mg·kg^-1）， and modified Shaofu Zhuyutang low-， medium-， and high-dose groups （7.5， 15， 30 g·kg^-1）， with 12 animals in each group. After 4 weeks of drug administration， voluntary activity and heat pain latency were observed. The rats were sacrificed for tissue collection， and Masson staining were used to observe histopathological changes in the endometrial tissues. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of interleukin-18 （IL-18）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and transforming growth factor-β （TGF-β）. Immunohistochemistry （IHC） was used to detect the protein expression area of tumor necrosis factor-related factor 6 （TRAF6） and NLPR3 in the endometrial tissues. Immunofluorescence （IF） was used to detect the relative fluorescence intensity of Caspase-1 and gasdermin D （GSDMD） in the endometrial tissues. Western blot was employed to measure the relative expression of TRL4， myeloid differentiation factor 88 （MyD88）， TRAF6， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， and NLPR3 proteins in endometrial tissues. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of TRL4， MyD88， TRAF6， NF-κB， and NLPR3 in the endometrial tissues. ResultsCompared with the sham-operated group， rats in the model group showed reduced voluntary activity and shorter heat pain latency. Serum levels of IL-18， IL-1β， TNF-α， and TGF-β were elevated. The relative expression areas of TRAF6 and NLPR3 proteins were increased， and the relative fluorescence intensity of Caspase-1 and GSDMD was enhanced. The relative expression of TRL4， MyD88， TRAF6， NF-κB p65， p-NF-κB p65， and NLPR3 proteins， along with the expression of TRL4， MyD88， TRAF6， NF-κB， and NLPR3 mRNA， were significantly increased （P<0.01）. Compared with the model group， rats in the progesterone group and the modified Shaofu Zhuyutang medium- and high-dose groups exhibited improved voluntary activity， longer heat pain latency， the fibrosis of endometrial tissue is alleviated. Serum levels of IL-18， IL-1β， TNF-α， and TGF-β were decreased. The relative expression areas of TRAF6 and NLPR3 proteins decreased， and the relative fluorescence intensity of Caspase-1 and GSDMD weakened. The relative expression of TRL4， MyD88， TRAF6， p-NF-κB p65， NLPR3 proteins， and TRL4， MyD88， TRAF6， NF-κB， and NLPR3 mRNA expression were reduced （P<0.05， P<0.01）. ConclusionModified Shaofu Zhuyutang may play a therapeutic role in endometriosis by interfering with key proteins in the TRL4/NF-κB/NLPR3 signaling pathway， reducing NLRP3 inflammasome-induced cellular pyroptosis， antagonizing the fibrosis process in ectopic endometrial tissues， improving the inflammatory microenvironment in the pelvic cavity， and alleviating pain.

By consulting the ancient Chinese herbal books， medical books and formularies of the past dynasties， and combining with modern research data， this paper makes a systematic textual research on the name， origin， place of origin， traditional quality evaluation， harvesting and processing of Selaginellae Herba， so as to provide a basis for the development and utilization of the relevant famous classical formulas. According to the textual research， Juanbai is the correct name of the herbal medicine in all dynasties， and there are also aliases such as Baozu， Qiugu， Jiaoshi and Jiusi Huanhuncao. The origin of Selaginellae Herba in the ancient herbal books was Selaginella tamariscina in all dynasties. Since the Republic of China， S. pulvinata has been gradually used as another origin of Selaginellae Herba. In ancient times， the producing area of S. tamariscina was mainly in Shandong， Hebei， Henan， Shaanxi， Jiangsu and Sichuan， etc. Nowadays， it is produced all over the country. S. pulvinata is mainly produced in Guangxi， Fujian， Sichuan， Guizhou， Yunnan， Hebei and so on. Since the recent times， it is concluded that the quality of the green color， complete and unbroken is good. Before the Qing dynasty， it was recorded that the harvesting time of Selaginellae Herba was generally from April to July， and it was expanded to all year round since the Qing dynasty. After harvesting， remove the sediment（sand and mud）， cut off the fibrous roots and dry in the shade or in the sun. The processing methods in all dynasties were mainly carbonizing by stir-frying and stir-bake to brown， and some ancient books contained the processing method of brine boiling， which was rarely used in modern times. Based on the results， it is recommended that S. tamariscina should be used as the base material of Selaginellae Herba. Because of more impurities， it should be fully purified to ensure the cleanliness of the herb， and the processing method can be based on the prescription requirements， if the processing requirements are not specified， the raw products can be used， charcoal products is recommended for use as an hemostatic.

Objective To explore the value of fractional order calculus(FROC)model diffusion weighted imaging(DWI)for evaluating pathological classification and differentiation degree of cervical cancer(CCA).Methods Totally 74 CCA patients were enrolled and divided into squamous cell carcinoma(SCC)group(n=54)and adenocarcinoma(ACA)group(n=20)based on pathological classification,also low differentiation group(n=33)and medium-high differentiation group(n=41)based on differentiation degree.Conventional MR examination and DWI with 12 b-values were performed,FROC model parameters(D,β,and p value)and the apparent diffusion coefficient(ADC)of mono-exponential model were obtained via software analysis.The parameters were compared between groups,and receiver operating characteristic curve of those being significantly different between groups were drawn,the area under the curves(AUC)were calculated to evaluate the diagnostic efficacy.Results Significant differences of ADC,D,and β values were found between SCC group and ACA group(all P＜0.05),and D value had the highest AUC(0.726)for distinguishing pathological classification CCA.Meanwhile,significant differences of D,β,p values and ADC were observed between low differentiation group and medium-high differentiation group(all P＜0.05),D value also had the highest AUC(0.865).AUC of the combined model constructed based on significant variables β and p values in logistic regression was 0.926,higher than that of each parameter alone(all P＜0.05).Conclusion FROC model DWI could be used to evaluate pathological classification and differentiation degree of CCA.

Gypenosides, structurally analogous to ginsenosides and derived from a sustainable source, are recognized as the principal active compounds found in Gynostemma pentaphyllum, a Chinese medicinal plant used in the treatment of the metabolic syndrome. By bioactive tracking isolation of the plants collected from different regions across China, we obtained four new gypenosides (1-4), together with nine known gypenosides (5-13), from the methanol extract of the plant. The structures of new gypenosides were elucidated by one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectra, complemented by chemical degradation experiments. Through comprehensive evaluation involving COL1A1 promoter assays and PP2Cα activity assays, we established a definitive structure-activity relationship for these dammarane-type triterpenoids, affirming the indispensability of the C-3 saccharide chain and C-17 lactone ring in effectively impeding extracellular matrix (ECM) deposition within hepatic stellate cells. Further in vivo study on the CCl₄-induced liver damage mouse model corroborated that compound 5 significantly ameliorated the process of hepatic fibrosis by oral administration. These results underscore the potential of dammarane-type triterpenoids as prospective anti-fibrotic leads and highlight their prevalence as key molecular frameworks in the therapeutic intervention of chronic hepatic disorders.

Objective:To explore the mechanism of Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma medicinal pair in delaying heart aging based on animal experiments, network pharmacology and molecular docking. Methods:Mice were divided into control group, aging group, metformin group and TCM group according to random number table method. All the groups were injected subcutaneously by D-galactose except the control group to build the subacute aging model. Two weeks later, the metformin group was given metformin suspension (150 mg/kg), the TCM group was given Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma lyophilized powder solution (650 mg/kg), and the control group and aging group were given an equivalent volume of ultrapure water by gastric gavage, once a day, six times a week, for 10 weeks. The level of heart TERT mRNA was detected by PCR; the expression of heart p53 was observed by immunohistochemical staining; the morphology of heart tissue was observed by HE staining. TCMSP and SwissTargetPrediciton databases were used to retrieve the active components and targets of Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma medicinal pair; TTD, OMIM, Gene, HAGR, DisGeNET and other data platforms were used to screen the targets of heart aging; after the drug and disease targets were intersected, the active components of them were collected; STRING database, Cytoscape 3.8.0 software, etc. were used to make PPI of the intersection targets, and screen out the key targets; FunRich was used to perform enrichment analysis of cellular components, molecular functions, biological processes, and biological signal pathways for key targets; Schr?dinger Maestro software was used to do the molecular docking of the screened active components and key targets, and docking results were visualized via PyMOL 2.1 software. Results:Experiment results showed that Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma could significantly ameliorate the damage of aging heart tissues, elevate TERT mRNA level, while significantly reducing the positive expression of p53. A total of 32 active components from the medicinal pair were screened, corresponding to 637 target genes. There were 263 targets for heart aging, and 67 intersection targets of drug active component targets and heart aging targets. 31 key targets were obtained after screening. Enrichment analysis showed that molecular functions were related to transcription factor activity and protein-tyrosine kinase activity. Biological processes involved signal transduction and cell communication. Signaling pathways mainly involved PDGFR-beta, PI3K-Akt, S1P1, Glypican, TRAIL, and Glypican 1. The molecular docking results showed that kaempferol, suchilactone, and ginsenoside Rg5_qt in the medicinal pair had a strong binding ability to p53. Conclusion:Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma may achieve the effect of delaying heart aging by inhibiting p53 expression, providing a foundation for further research on mechanism of invigorating qi and activating blood circulation drugs to delay heart aging.
