Polycystic ovary syndrome （PCOS） is a common reproductive-endocrine and metabolic disorder in women of reproductive age， and chronic low-grade inflammation is closely associated with its pathogenesis. Studies have confirmed that the abnormal activation of NOD-like receptor protein 3 （NLRP3） inflammasome， a key complex of the innate immune system， not only mediates the formation of local ovarian inflammatory microenvironment， but also deeply participates in the processes of hyperandrogenemia， follicular developmental arrest and systemic insulin resistance in PCOS patients. A variety of single-herb medicines and their active ingredients （such as ginsenosides， evening primrose oil， safflower yellow， etc.）， as well as compound prescriptions including Jianpi yishen huazhuo formula， Bushen huatan formula and Bushen huoluo decoction， can effectively alleviate chronic low-grade inflammation related to PCOS， ameliorate insulin resistance， hyperandrogenemia and abnormal ovarian microenvironment by inhibiting the abnormal activation of NLRP3 inflammasome， and ultimately promote follicular development and the recovery of ovulatory function. Nevertheless， the methodological quality of existing studies is generally low， and clinical translation is still restricted by the heterogeneity of experimental models， unclear pharmacodynamic material basis and lack of high-quality evidence-based data. Multi-omics technologies should be adopted in future research to further analyze the compatibility rules of Chinese herbal compound prescriptions， and stratified studies should be carried out according to different phenotypes of PCOS.

Chinese medicinal materials serve as the material foundation of traditional Chinese medicine （TCM） culture. The sustainable development of Chinese medicinal material resources is a focal point in the modernization of TCM. With the increasing scarcity of Chinese medicinal material resources， the expansion of new Chinese medicinal material resources has become a crucial means for the sustainable utilization of these resources. New Chinese medicinal material resources refer to natural resources that have been newly discovered or developed， possessing potential medicinal value or healthcare functions， which fall outside the traditional application scope of herbal medicines. These resources have not yet been widely recognized or applied within the framework of traditional TCM theory. They specifically include artificial substitutes for endangered medicinal materials， new medicinal parts of medicinal plants， medicinal materials with expanded clinical applications， and foreign medicinal resources. The rational compatability and formulation of new Chinese medicinal material resources are essential pathways for integrating them into the TCM system. Due to the weak foundational research on new Chinese medicinal material resources in China， the characteristics of these resources that align with the TCM theory are not yet fully understood， posing numerous constraints on formulating prescriptions based on the traditional compatibility principles of TCM. This paper integrates the traditional formulation theory of TCM with modern data integration methods， proposing four formulation models for new TCM resources： synergistic compatibility， substitutive compatibility， symptom-based compatibility， and efficacy semantic compatibility. These models provide new insights for the application of new Chinese medicinal material resources， not only facilitating their rational use in clinical practice but also offering theoretical support for the development and compatibility research of these resources.

Objective To observe clinical efficacy of Danggui Yinzi prescription combined with focused ultrasound in treatment of vulvar lichen sclerosus(VLS)with blood deficiency and dryness.Methods A total of 60 patients with blood deficiency and dryness VLS hospitalized in Gansu Provincial Hospital of Traditional Chinese Medicine from September 2023 to September 2024 were selected as study subjects,they were divided into control group(n=30)and treatment group(n=30)by random number table method.Control group was treated with focused ultrasound,and treatment group was treated with oral Danggui Yinzi prescription on the basis of control group.After 1 month of treatment,symptom scores(skin lesion area,color,etc.)and clinical efficacy of two groups were compared.Results After treatment,symptom scores of two groups were lower than those before treatment,and symptom scores of treatment group were lower than those of control group.Total effective rate of treatment group was higher than that of control group(P＜0.05).Conclusion Danggui Yinzi prescription combined with focused ultrasound is effective in treatment of VLS with blood deficiency and dryness,which can significantly reduce or eliminate itching symptoms and promote skin healing.

OBJECTIVE From the perspective of China’s health system， to evaluate the economic efficiency of Irinotecan liposome+fluorouracil+calcium folinate+oxaliplatin（NALIRIFOX regimen） versus paclitaxel （albumin-bound） combined with gemcitabine （AG regimen） in the first-line treatment of metastatic pancreatic cancer. METHODS A dynamic Markov model was constructed based on the data from the NAPOLI 3 clinical trial， with a cycle period of 28 days and a simulation time limit of 5 years. Incremental cost-effectiveness ratio （ICER） and quality-adjusted life year （QALY） were used as the model output indicators. The willingness-to-pay （WTP） threshold was set at three times China’s 2024 per capita gross domestic product （GDP）， and a discount rate of 5% was adopted. A cost-utility analysis was conducted to analyze the economic efficiency of the NALIRIFOX regimen compared to the AG regimen. Univariate sensitivity analysis and probabilistic sensitivity analysis were used to evaluate the robustness of the model results， and scenario analysis was conducted by reducing the cost of irinotecan liposome by 60% and 70%. RESULTS The base-case analysis showed that the ICER of the NALIRIFOX regimen was 854 669.96 yuan/QALY compared to the AG regimen， which was greater than the WTP threshold （287 247 yuan/QALY）， indicating that the NALIRIFOX regimen was not economically efficient. The univariate sensitivity analysis results indicated that the discount rate， the cost of irinotecan liposome， the utility value of the progression-free survival state， and the utility value of the disease progression state had a significant impact on the ICER. The probabilistic sensitivity analysis results showed that under the WTP threshold of this study， the NALIRIFOX regimen was not economically efficient compared with the AG regimen. The scenario analysis results indicated that when the price was reduced by 70%， the probability of the NALIRIFOX regimen being economically efficient compared with the AG regimen was 9.60%. CONCLUSIONS From the perspective of China’s health system， when the WTP threshold is set at three times China’s 2024 per capita GDP， the NALIRIFOX regimen is not economically efficient in the first-line treatment of metastatic pancreatic cancer， compared with the AG regimen.

BACKGROUND:Ovarian tissue vitrification cryopreservation is one of the important methods for preserving fertility.Tanshinone ⅡA has various pharmacological activities,including anti-oxidation,inhibition of inflammatory response,and reduction of apoptosis,but its role as an additive for vitrification cryoprotection of ovarian tissue is still unclear.OBJECTIVE:To explore the protective effect of tanshinone ⅡA on vitrification cryopreservation of mouse ovarian tissue.METHODS:Twenty-five 6-week-old female KM mice were randomly selected and their ovarian tissues were randomly divided into five groups,with 10 ovaries per group.The fresh group was not cryopreserved.The frozen control group used vitrification cryoprotectant.The 0.5,2.5,and 5 μmol/L tanshinone ⅡA groups used vitrification cryoprotectant containing 0.5,2.5,and 5 μmol/L tanshinone ⅡA,respectively,and were cryopreserved in liquid nitrogen.After 3 days of storage,the cryopreserved tubes were taken out and thawed.The ovarian tissue and follicle morphology of each group were observed by hematoxylin-eosin staining,and the normal follicle morphology and survival rate were analyzed.The levels of superoxide dismutase,catalase,malondialdehyde,tumor necrosis factor-α,interleukin-1β,and interleukin-17 in the ovary were detected by enzyme-linked immunosorbent assay.RT-qPCR and western blot assay were used to detect the mRNA and protein expressions of nuclear factor E2-related factor 2(Nrf2)and heme oxygenase 1(HO-1)in the mouse ovary.RESULTS AND CONCLUSION:(1)Compared with the fresh group,the frozen control group had abnormal morphology of follicles at all levels in the ovary,decreased follicle survival rate(P＜0.05),decreased superoxide dismutase and catalase activities(P＜0.05);the levels of malondialdehyde,and tumor necrosis factor α,interleukin 1β,and interleukin 17 were all increased(P＜0.05),and the mRNA and protein expressions of Nrf2 and HO-1 were decreased(P＜0.05).(2)Compared with the frozen control group,different concentrations of tanshinone ⅡA could improve the morphology of follicles at all levels in the ovary,increase the survival rate of follicles,enhance the activities of superoxide dismutase and catalase,and reduce the levels of malondialdehyde,tumor necrosis factor α,interleukin 1β,and interleukin 17,increased the mRNA and protein expression of Nrf2 and HO-1 in a concentration-dependent manner,with 5 μmol/L tanshinone ⅡA having the most significant effect.(3)The results show that tanshinone ⅡA may reduce the oxidative stress level and inflammatory response of mouse ovarian tissue by mediating the Nrf2/HO-1 signaling pathway,thereby alleviating the reproductive damage caused by vitrification cryopreservation of mouse ovaries.

Aim To explore the clinical efficacy of sequential balloon pulmonary angioplasty(BPA)in the treat-ment of patients with chronic thromboembolic pulmonary hypertension(CTEPH),and analyze the safety during the periop-erative period.Methods 30 patients with CTEPH who underwent BPA treatment at Luoyang Central Hospital affiliated to Zhengzhou University from August 2018 to February 2024 were selected,30 patients with CTEPH who chose drug treatment were set as controls,the patients'gender,age,body mass index,comorbidities,plasma N-terminal pro-brain natriuretic peptide(NT-proBNP)levels,application of pulmonary hypertension targeted drugs,6-minute walking dis-tance(6-MWD),WHO cardiac function classification and cardiac ultrasound pulmonary arterial pressure related data were collected.Right heart catheterization was performed to obtain pulmonary hemodynamic parameters in the BPA group.Changes in WHO cardiac function classification,6-MWD,NT-proBNP,pulmonary vascular hemodynamic parameters and cardiac ultrasound pulmonary artery pressure data before BPA,after the final BPA and at 6-month follow-up were com-pared,as well as differences between the two groups.The occurrence and management results of surgical complications such as pulmonary artery injury,contrast nephropathy and reperfusion pulmonary edema were recorded.Results Compared with before BPA,after the last BPA,cardiac output(CO),cardiac index(CI),and mixed venous oxygen satu-ration(SvO2)increased,mean pulmonary artery pressure(mPAP)and pulmonary vascular resistance(PVR)decreased(all P＜0.05),and 6-MWD,NT-proBNP,right ventricular diameter,right atrial up-down diameter,right atrial left-right diameter,left ventricular diastolic end diameter,and tricuspid regurgitation velocity all improved(all P＜0.05).Com-pared with the control group,the surgical group showed an increase in 6-MWD,a decrease in NT-proBNP levels,a de-crease in right ventricular diameter,right atrial up-down diameter and right atrial left-right diameter,an increase in left ventricular end diastolic diameter,a decrease in tricuspid regurgitation velocity and a significant improvement in WHO car-diac function classification(all P＜0.05).Among 30 BPA patients,2 patients experienced hemoptysis during surgery,1 patient developed reperfusion pulmonary edema after surgery,and 1 patient developed contrast nephropathy.After treat-ment,all patients improved and were discharged.Conclusion Sequential BPA has good clinical efficacy and safety in the treatment of CTEPH patients,and is an effective technique for treating CTEPH,which is worth promoting in clinical practice.

Objective To evaluate the cost-effectiveness of the combination therapy of ribociclib plus fulvestrant compared to fulvestrant monotherapy as a second-line treatment for postmenopausal patients with hormone receptor-positive(HR+)/human epidermal growth factor receptor 2-negative(HER2-)advanced metastatic breast cancer from the perspective of the Chinese healthcare system.Methods A partitioned survival model was constructed based on MONALEESA-3 study data,with the model cycle of 4 weeks and the time range of 15 years.Total cost,quality-adjusted life years(QALYs)and incremental cost-effectiveness ratio(ICER)were compared between ribociclib combined with fulvestrant and fulvestrant monotherapy as a second-line treatment for postmenopausal patients with HR+/HER2-advanced metastatic breast cancer.The robustness of the models was validated through one-way sensitivity analysis and probabilistic sensitivity analysis.Results Compared with the fulvestrant monotherapy regimen,the ICER for the ribociclib combined with fulvestrant regimen was 187,958.06 yuan/QALY,which was below the willingness-to-pay(WTP)threshold of three times China's per capita gross domestic product(GDP)in 2024(287,247 yuan/QALY).The one-way sensitivity analysis revealed that the ICER was primarily influenced by the proportion of patients receiving subsequent treatments with the combination therapy or fulvestrant monotherapy,and the utility value of progression-free survival.The probabilistic sensitivity analysis showed that at a WTP threshold of three times China's per capita GDP in China in 2024(287,247 yuan/QALY),the probability of the ribociclib combination therapy being cost-effective was 100%.Conclusion In the context of the Chinese healthcare system,the combination therapy of ribociclib and fulvestrant is more cost-effective than fulvestrant monotherapy for the second-line treatment of postmenopausal patients with HR+/HER2-advanced metastatic breast cancer.
