Polycystic ovary syndrome （PCOS） is a common gynecological endocrine and reproductive disorder，with the main clinical manifestations including ovulation failure，insulin resistance，hyperandrogenism，and obesity. Its occurrence and development are closely related to cellular regulatory mechanisms such as apoptosis，autophagy，oxidative stress，and inflammatory response. Autophagy，as a clearance mechanism that maintains cellular homeostasis，plays a crucial role in maintaining the growth，development，and maturation of oocytes. Exploring the mechanism of autophagy during the occurrence and development of diseases can help develop treatment methods for PCOS by regulating autophagy. Studies have shown that autophagy plays an important role in the pathogenesis of PCOS，and it can affect the occurrence and development of PCOS through multiple pathways，levels，and targets. Traditional Chinese medicine （TCM） regulates autophagy in ovarian granulosa cells or endometrium of patients with PCOS by targeting the expression of autophagy signaling pathways，regulatory factors，and non-coding single-stranded RNA molecules，thereby alleviating inflammation，regulating metabolism disorders，and balancing hormone levels in PCOS. Accordingly，TCM can ameliorate pathological conditions such as insulin resistance，hyperandrogenism，and ovulation failure in PCOS. This article summarizes the TCM formulas and extracts for the treatment of PCOS，as well as the main autophagy pathways and regulatory factors involved，aiming to provide reference and suggestions for the future treatment of PCOS with TCM by regulating autophagy.

OBJECTIVE To evaluate the cost-effectiveness of finerenone combined with standard of care （SoC） in the treatment of heart failure with mildly reduced ejection fraction （HFmrEF） or preserved ejection fraction （HFpEF）. METHODS Based on a phase Ⅲ clinical trial， a Markov model was constructed from the perspective of China’s healthcare system to compare the treatment outcomes of finerenone combined with SoC regimen versus SoC regimen alone in the treatment of different cardiac functional statuses of HFmrEF/HFpEF. Using quality-adjusted life year （QALY） as the health output index， 3 times China’s per capita GDP in 2023 as the willingness-to-pay （WTP） threshold， a simulation was conducted with a 3-month cycle length and a 10- year time horizon， incorporating an annual discount rate of 5%. The dynamic changes across various stages of HFmrEF/HFpEF treated with finerenone combined with SoC versus SoC alone were simulated to evaluate the long-term effectiveness and costs of the two treatment strategies. Additionally， one-way sensitivity analysis and probabilistic sensitivity analysis were performed， to test the robustness of the results. RESULTS The incremental cost-effectiveness ratio （ICER） of the finerenone combined with SoC regimen versus SoC regimen alone was 179 504.75 yuan/QALY， which was below the WTP threshold set in this study， indicating that the finerenone combined with SoC regimen possessed certain economic advantages. The results of one-way sensitivity analysis showed that the utility value of NYHA Ⅱ status， the drug price of finerenone， the discount rate， and the probability of hospital transfer for both groups had a great influence on ICER， but did not affect the robustness of the model. The probabilistic sensitivity analysis also confirmed the robustness of the model. CONCLUSIONS Under the WTP threshold set in this study， finerenone combined with SoC is cost-effective in the treatment of HFmrEF/HFpEF， compared with the SoC regimen.

OBJECTIVE To analyze the correlation of the peak blood concentration （cmax） of compound sulfamethoxazole （TMP/SMZ） and its metabolite N-acetyl sulfamethoxazole （NSMZ） with clinical efficacy and adverse reactions in critically ill patients. METHODS The data of critically ill patients treated with TMP/SMZ in various ICU of Hainan General Hospital from December 2023 to January 2025 were retrospectively collected. The patients were divided into success group and failure group based on the treatment outcome. Simple linear regression and Spearman correlation analysis were used to analyze the correlation of TMP cmax， SMZ cmax， and NSMZ cmax with clinical efficacy and adverse reactions. The receiver operating characteristic curve （ROC） was used to determine the cutoff values of cmax for predicting the occurrence of adverse reactions. RESULTS Among critically ill patients with an acute physiology and chronic health evaluation Ⅱ （APACHE-Ⅱ） ≥15 points 24 h of check-in at ICU， SMZ cmax of success group was significantly higher than failure group （P＜0.05）. The daily total dose of TMP/SMZ was positively correlated with TMP cmax and SMZ cmax（ P＜0.05）. TMP cmax was significantly correlated with hepatotoxicity and nephrotoxicity， SMZ cmax with hepatotoxicity， and NSMZ cmax with nephrotoxicity （P＜0.05）. The cutoff values of TMP cmax for predicting nephrotoxicity and hepatotoxicity were 7.25 μg/mL and 6.63 μg/mL， respectively. The cutoff value of SMZ cmax for predicting hepatotoxicity was 138.00 μg/mL， and that of NSMZ cmax for predicting nephrotoxicity was 60.76 μg/mL. CONCLUSIONS Among critically ill patients with an APACHE-Ⅱ ≥15 points 24 h of check-in at ICU， SMZ cmax is associated with treatment success. Hepatotoxicity risk significantly increases when TMP cmax ≥6.63 μg/mL or SMZ cmax ≥138.00 μg/mL； nephrotoxicity risk significantly increases when TMP cmax ≥7.25 μg/mL or NSMZ cmax ≥60.76 μg/mL.

ObjectiveTo investigate the mechanism by which Mingshi prescription regulates the retinal melanopsin-dopamine （Opn4-DA） axis in myopic mice to inhibit endoplasmic reticulum （ER） stress in the retina and sclera， thereby delaying axial elongation associated with myopia. MethodsSixty 4-week-old male SPF-grade C57BL/6J mice were randomly divided into a normal group， a form-deprived myopia group （FDM group）， an intrinsically photosensitive retinal ganglion cells ablation group （ipRGCs group）， a Mingshi Prescription group （MSF group， 5.2 g·kg^-1）， and an ipRGCs + MSF group （5.2 g·kg^-1）. Except for the normal group， all other groups underwent FDM modeling. Additionally， the ipRGCs and ipRGCs + MSF groups received retinal ipRGC ablation. Three weeks after modeling， the MSF and ipRGCs + MSF groups were administered Mingshi prescription via continuous gavage for six weeks. After refraction and axial length were measured in all mice， eyeballs were collected along with retinal and scleral tissues. Pathological and morphological changes in the retina， choroid， and sclera were observed using periodic acid-Schiff （PAS） staining. Western blot was employed to detect the relative protein expression levels of dopamine D1 receptor （DRD1）， C/EBP homologous protein （CHOP）， and glucose-regulated protein 78 （GRP78） in the retina， and CHOP and GRP78 in the sclera. Real-time PCR was used to detect the relative mRNA expression of Opn4， CHOP， and GRP78 in the retina， and CHOP and GRP78 in the sclera. Immunofluorescence staining （IF） was performed to detect the expression of Opn4 and DRD1 in retinal tissues. ResultsCompared with the normal group， the FDM group showed a significant myopic shift in refraction （P<0.05） and a significant increase in axial length （P<0.05）. The retinal layers were thinner， the number of ganglion cells was reduced， and collagen fibers in the sclera were loosely arranged with evident gaps. Opn4 and DRD1 protein and mRNA expression in the retina were significantly decreased （P<0.05）， while CHOP and GRP78 protein and mRNA expression in both retinal and scleral tissues were significantly increased （P<0.05）. Compared with the FDM group， the ipRGCs group exhibited further increases in myopic refraction and axial length （P<0.05）， more pronounced thinning and looseness in the retinal， choroidal， and scleral layers， lower expression of Opn4 and DRD1 protein and mRNA in the retina （P<0.05）， and higher expression of CHOP and GRP78 protein and mRNA in the retina and sclera （P<0.05）. Compared with the FDM group， the MSF group showed significantly reduced refractive error and axial length （P<0.05）， with improved cellular number， arrangement， and thickness in ocular tissues， increased Opn4 and DRD1 protein and mRNA expression in the retina （P<0.05）， and reduced CHOP and GRP78 protein and mRNA expression in both retina and sclera （P<0.05）. Similarly， the ipRGCs + MSF group showed significant improvements in terms of the above items compared with the ipRGCs group （P<0.05）. ConclusionMingshi Prescription delays myopic axial elongation and refractive progression by regulating the Opn4-DA axis in the retina of myopic mice， thereby inhibiting ER stress in the retina and sclera. This intervention promotes Qi and blood nourishment of the eyes， softens the fascia， and restores ocular rhythm.

Objective To investigate the relationship between serum interleukin-1β(IL-1β),C-reactive pro-tein to albumin ratio(CAR)and heparin-binding protein(HBP)levels and secondary pulmonary Candida albi-cans infection during chemotherapy in patients with lung cancer.Methods A total of 175 patients with lung cancer admitted to this hospital from January 2018 to April 2022 were selected,and all patients were treated with chemotherapy.According to whether they had secondary pulmonary Candida albicans infection,they were divided into infection group(37 cases)and non-infection group(138 cases).The clinical data,serum levels of IL-1β,HBP and CAR were compared between the two groups.Multivariate Logistic regression analysis was used to analyze the influencing factors of secondary pulmonary Candida albicans infection in patients with lung cancer during chemotherapy.The receiver operating characteristic(ROC)curve was used to analyze the pre-dictive value of serum IL-1β,CAR and HBP for secondary pulmonary Candida albicans infection during chemo-therapy,and the prognosis of lung cancer patients with different serum IL-1β,HBP levels and CAR were com-pared.Results There were significant differences in smoking,pathological stage,diabetes mellitus,chemo-therapy cycle,chronic obstructive pulmonary disease and anatomical location between the infection group and the non-infection group(P＜0.05).The serum levels of IL-1β,HBP and CAR in the infection group were higher than those in the non-infection group(P＜0.05).Multivariate Logistic regression analysis showed that smoking,diabetes,anatomical site,chronic obstructive pulmonary disease,pathological stage,chemotherapy cycle and serum IL-1β,HBP,CAR were the influencing factors of secondary pulmonary Candida albicans infec-tion in patients with lung cancer during chemotherapy(P＜0.05).The area under the curve(AUC)of serumIL-1β,CAR and HBP in predicting pulmonary Candida albicans infection was 0.779,0.732 and 0.796,respec-tively.The AUC of the combination of the three was 0.931,and the sensitivity and specificity were 86.49％and 90.58％,respectively.The survival rate of lung cancer patients with high levels of IL-1β,CAR and HBP was sig-nificantly lower than that of patients with low levels of Il-1β,CAR and HBP(P＜0.05).Conclusion The in-crease of serum IL-1β,CAR and HBP levels in patients with lung cancer is related to secondary pulmonary Candida albicans infection during chemotherapy.Detection of these serum Il-1β,CAR and HBP levels is helpful to predict the risk of pulmonary Candida albicans infection and death.

Objective To analyze the causal relationship between serum sex steroid hormone levels and myopia with the Mendelian randomization(MR)methods.Methods Sex hormone genetic tools classified by sex were publicly availa-ble summarized statistical data from the Genome-wide association study(GWAS)of the UK Biobank Consortium on sex hormone-binding globulin(SHBG),total testosterone(TT),bioavailable testosterone(BT),and estradiol(E2).The GWAS summarized statistical data for myopia were obtained from publicly available data published by the FinnGen Consorti-um R10.All data were downloaded from April 18 to April 31,2024 from the corresponding databases and analyzed.All re-sults from the MR study were mainly analyzed by inverse-variance weighting(IVW)method.Results The study showed that a higher serum SHBG level in European increased the risk of myopia development in women(IVW,OR=1.152,95％CI:1.014-1.308,P=0.029);low serum TT level(IVW,OR=0.821,95％CI:0.697-0.967,P=0.018)and serum BT lev-el(IVW,OR=0.820,95％CI:0.691-0.972,P=0.022)increased the risk of myopia development in women.There was no causal relationship between serum SHBG,TT,and BT levels and myopia in men.There was no causal effect between E2 level and myopia in women and men.The stability of our findings was supported by sensitivity analysis.Conclusion In-creased serum SHBG level and decreased serum TT and BT levels are associated with an increased risk of myopia in women,whereas no such association is found in men.There is no causal relationship between E2 and myopia.

Objective To investigate the application value of prognostic nutritional index and urea/creatinine ratio in nutritional status assessment for patients with esophageal cancer undergoing radiotherapy and chemotherapy.Methods A total of 138 patients with esophageal cancer who received radiotherapy and chemotherapy were screened.NRS 2002 nutritional screening was used as the standard.Prognostic nutritional index(PNI)and urea/cre-atinine ratio(UCR)were used to evaluate the malnutrition of patients with esophageal cancer.ROC curve was used to evaluate and compare the diagnostic efficacy of different nutritional screening tools.Results The biochemical and hematological indexes of patients with esophageal cancer showed certain characteristics,in which the levels of urea,creatinine,UCR,ALB,PALB,TP,TC,TG,HDL and LDL all fluctuated within the normal range.In terms of nutritional risk screening,the NRS 2002 score identified nutritional risk in 57.97%of patients,while the PNI and UCR predicted nutritional risk in 31.16%and 40.58%of patients,respectively.Consistency test showed that the Kappa value of PNI and NRS 2002 scores was 0.460(P<0.05),and the Kappa value of UCR and NRS 2002 scores was 0.522(P<0.05),indicating that there was a certain correlation between them and NRS 2002 scores in nutri-tional risk screening.Correlation analysis showed that NRS 2002 score was significantly correlated with UCR,ALB,PALB,PBL,Cr,HDL and TP(P<0.05),while PNI was significantly correlated with ALB,PALB,PBL,Cr,HDL,TP and UREA(P<0.05).There were significant correlations between UCR and PALB,UREA and Cr(P<0.05).Logistic univariate regression analysis further confirmed these correlations and revealed that malnutrition was negatively correlated with albumin,prealbumin,total protein,lymphocytes,creatinine and BMI,and positively correlated with urea.However,multivariate regression analysis did not find any statistical difference between these related factors and the two objective evaluation measures.The results of diagnostic efficacy evaluation showed that the area under ROC curve of PNI and UCR evaluation to predict esophageal cancer malnutrition was 0.779 and 0.736,respectively,with statistical significance(P<0.001).Among them,UCR showed higher sensitivity and PNI showed higher specificity,but there was no significant difference in diagnostic value between them.Conclusion PNI and UCR as nutritional assessment tools have certain application value in the nutritional risk screening of patients with esophageal cancer,but their consistency with NRS 2002 score needs to be improved.When assessing the nutritional status of patients,a combination of various indicators and methods should be used to achieve more accurate diagnostic results.
