The oocyte， as the origin of life， provides half the chromosomes to the embryo and supplies the proteins， substrates， energy， and other support necessary for embryonic development. It is the decisive factor determining the embryo's developmental potential. Infertility caused by reproductive endocrine diseases targets the oocyte as the final target cell. Improving oocyte quality represents a key and difficult point in the field of modern reproductive medicine. The decline of oocyte quality is related to meiosis abnormalities， DNA damage， mitochondrial dysfunction， oxidative stress， and other mechanisms. For oocyte quality problems， there is no unified international guideline to recommend drugs. Because the drug intervention research on oocytes involves strict clinical ethical restrictions， the current relevant research only stays in the animal and in vitro experimental stage and has not yet been applied to the clinic. Traditional Chinese medicine compound formula has a multi-target and multi-pathway regulation mechanism and is widely used in clinics. More and more research began to pay attention to the potential mechanism of traditional Chinese medicine compound formulas in improving oocyte quality. Traditional Chinese medicine compound formula has the advantages of multi-target and multi-channel synergy as well as better safety， individualization， and conformity to clinical ethics in improving oocyte quality. This article systematically reviewed the research progress on traditional Chinese medicine compound formula interventions for oocyte quality， aiming to summarize existing findings and provide recommendations to improve oocyte quality and optimize the clinical diagnosis and treatment of female infertility within traditional Chinese medicine.

Immunotherapy for cancer,as an emerging treatment modality,has made significant strides in recent years and has become a crucial therapeutic approach following surgery,radiotherapy,chemotherapy,and targeted therapy.In particular,the clinical utilization of immune checkpoint inhibitors(ICIs)has not only enhanced the survival rates of patients with refractory or recurrent tumors but has also significantly optimized the overall strategy for cancer treatment.However,as the population undergoing cancer immunotherapy continues to grow,this expansion not only yields clinical benefits but also precipitates a range of specific adverse reactions known as immune-related adverse events(irAEs).Pleural effusion is a common and severe complication in cancer patients,significantly affecting both their quality of life and treatment outcomes.Typically,tumor-related pleural effusion is often due to pleural metastasis,with malignant pleural effusion(MPE)characterized by rapid growth,being difficult to control,and tendency for recurrence.With the approval of new drugs and the expansion of indications for existing medications,the number of cancer patients receiving ICIs treatment is increasing,bringing ICIs-related pleural effusion into focus.While ICIs treatment-related pleural effusion is relatively rare in clinical practice,it is closely linked to treatment choices of patients and prognosis.Unlike MPE,the pathogenesis of ICIs treatment-related pleural effusion is more complex,not only involving non-specific immune activation leading to autoimmune inflammatory reactions but also potentially related to nodular pleural granulomatous reactions,eosinophilic chronic pleurisy,and tumor-infiltrating lymphocytes.In terms of diagnosis,ICIs treatment-related pleural effusion is typically diagnosed through exclusion,requiring the exclusion of other causes such as tumor progression,radiotherapy,and chemotherapy-induced pleural effusion,adding complexity and difficulty to the diagnostic process.Treatment for ICIs treatment-related pleural effusion often involves glucocorticoids,tocilizumab,or infliximab,aiming to alleviate symptoms and improve prognosis by suppressing excessive immune reactions.Preventing the occurrence of ICIs treatment-related pleural effusion is equally crucial,necessitating comprehensive patient assessment before ICIs administration and continuous monitoring during treatment to promptly detect and manage potential adverse reactions.Through this comprehensive management approach,the impact of ICIs treatment-related pleural effusion on patient quality of life and treatment outcomes can be minimized,optimizing overall treatment results.This review aimed to explore the pathogenesis,histological features,clinical manifestations,diagnostic methods and treatment strategies of ICIs treatment-related pleural effusion,and delve into the characteristics of ICIs treatment-related pleural effusion,in order to enhance understanding of this complication and provide a reference for clinical practice.

Objective To predict the pregnancy probability of patients and provide clinical guidance,the factors that affect the pregnancy outcome of patients with endometriosis(EM)after operation by machine learning were explored.Methods The clinical data of 167 EM patients after conservative surgery were analyzed retrospectively.Boruta algorithm was used to screen the features with high ranking,and four machine learning models,namely random forest,decision tree,support vector machine(SVM)classifier and extreme gradient lifting(XGBoost)were constructed.The performance of the model is evaluated based on four indicators:accuracy,recall,accuracy and area under curve(AUC)of receiver operating characteristic.Shapley additive interpretation(SHAP)was used to visualize the contribution of each variable to the pregnancy outcome and the positive and negative directions.Results Age,body mass index(BMI),postoperative CA125,preoperative CA125,the course of opportune capsule,the course of dysmenorrhea,the score of dysmenorrhea symptoms,the score of pelvic positive signs,the score of TCM symptoms and menstrual cycle were the important characteristics in the top ranking.The decision tree model(accuracy:0.66,accuracy:0.63,recall:0.62,AUC:0.67,F1:0.60)had the best average classification performance.Based on the results of SHAP analysis,age,BMI index,postoperative CA125 level and Traditional Chinese medicine syndrome score had significant effects on the outcome.The higher the value,the lower the postoperative pregnancy rate.Conclusion Age,BMI,postoperative CA125 level and traditional Chinese medicine syndrome score of patients with endometriosis after combined drug therapy are the main evaluation indexes that affect the pregnancy outcome of patients with endometriosis after combined drug therapy.When the values of these four characteristics are high,patients are not advised to conceive naturally,and appropriate assisted reproductive technology should be selected as soon as possible.

Objective:To compare the mydriatic effects of a combination of 1% tropicamide and 2.5% phenylephrine with a 0.5% tropicamide and 0.5% phenylephrine combination in patients with type 2 diabetes.Methods:A randomized, double-blind, controlled trial was conducted.Ninety Chinese patients (90 eyes) with dark irises and type 2 diabetes who needed mydriasis examination at the Fundus Disease Clinic of Tianjin Medical University Eye Hospital from June to September 2024 were included.The subjects were divided into control group (30 patients 30 eyes), high concentration group (30 patients 30 eyes) and half-dilution group (30 patients 30 eyes) using the random number table method, which received 2 drops of a mixture of 0.5% tropicamide and 0.5% phenylephrine, 2 drops of a mixture of 1% tropicamide and 2.5% phenylephrine, 1 drop of a mixture of 1% tropicamide and 2.5% phenylephrine+ 1 drop of saline respectively.The pupil diameter of the patients was measured with a pupillometer 40 minutes before and after instillation.The study adhered to the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2024KY-16).Written informed consent was obtained from all participants.Results:The proportions of patients whose pupil diameters reached 7 mm 40 minutes after the initial administration in the control group, high-concentration group, and half-dilution group were 56.7%(17/30), 86.7%(26/30) and 66.7%(20/30), respectively, with a statistically significant overall difference ( χ2=6.667, P=0.036).The proportion of patients in the high-concentration group whose pupil diameter reached 7 mm 40 minutes after the initial administration was higher than that in the control group, and the difference was statistically significant ( P<0.05).The pupil diameters 40 minutes after the initial administration in the control group, the high-concentration group and the half-dilution group were (7.01±0.86), (7.64±0.61) and (7.49±1.15)mm, respectively, with a statistically significant overall difference ( F=4.019, P=0.021), and the pupil diameter of the high-concentration group was significantly higher than that of the control group ( P=0.024).Changes in pupil diameter 40 minutes after the initial administration in the control group, high-concentration group and half-dilution group were (3.23±0.81), (3.82±0.60) and (3.62±0.75)mm, respectively, with a statistically significant overall difference ( F=5.121, P=0.008), and the change in pupil diameter in the high-concentration group was higher than that in the control group ( P=0.007). Conclusions:The combination of 1% tropicamide and 2.5% phenylephrine has better pupil dilation than the combination of 0.5% tropicamide and 0.5% phenylephrine.It is recommended that pupil dilation be performed with a high-concentration mydriatic drug prior to outpatient fundus examination for diabetic patients.

Objective:To explore the association between sleep and myopia among students aged 6-15 years in Tianjin.Methods:A cross-sectional study was conducted.A total of 218 864 primary and secondary school students aged 6-15 years in Tianjin were recruited from January 2023 to May 2023.Basic information and responses to the Children's Sleep Habits Questionnaire (CSHQ) were collected.Logistic regression models were used to assess the association between myopia and sleep.The study followed the Declaration of Helsinki, and the research protocol was approved by the Medical Ethics Committee of Tianjin Medical University Eye Hospital (No.ChiCTR2200065710). All questionnaires and demographic information were collected with parental consent.Results:It was found that 68 121(31.12%) students were myopic and 178 514(81.56%) had sleep disorders.The prevalence of myopia among students with average daily sleep durations of ≤8 hours, >8-9 hours, >9-10 hours, and >10 hours was 52.17%(9 288/17 803), 35.35%(31 037/87 787), 25.18%(24 481/97 216), and 20.64% (3 315/16 058), respectively, and the difference was statistically significant ( χ2=6 835.649, P<0.001). After adjusting for sex, age, body mass index, and potential confounding factors, compared with students with average daily sleep duration of >10 hours, students with average daily sleep durations of ≤8 hours ( OR=1.496, 95% CI: 1.415-1.581, P<0.001), >8-9 hours ( OR=1.364, 95% CI: 1.383-1.447, P<0.001), and >9-10 hours ( OR=1.257, 95% CI: 1.202-1.316, P<0.001) had a higher risk of myopia.Students with sleep disorders, bedtime resistance, sleep-onset delay, irregular sleep duration, sleep anxiety, night wakings, parasomnias, sleep-disordered breathing, and daytime sleepiness were more likely to be myopic. Conclusions:Sleep is a key factor influencing myopia among schoolchildren aged 6-15 years in Tianjin.

Objective:To construct patient-derived xenograft (PDX) models from head and neck squamous cell carcinoma (HNSCC) patients, to explore the effect of immune reconstitution timing on the PDX modeling and immune microenvironment in humanized immune system mice (huHSC-NCG-hIL15), and to provide a reliable animal model for research on the mechanisms of head and neck squamous carcinoma and for studies on immune therapy drug interventions.Methods:This study enrolled 28 HNSCC patients (25 laryngeal carcinomas, 3 hypopharyngeal carcinomas). PDX models were established in Balb/c nude (nu) mice, NSG mice, and humanized immune system-reconstituted huHSC-NCG-hIL15 mice. Fresh HNSCC samples were transplanted into Balb/c nu and NSG mice to generate PDX models, with subsequent analysis of success-associated factors. One successfully established PDX tumor was subsequently implanted into humanized immune system-reconstituted huHSC-NCG-hIL15 mice. Tumor transplantation was performed at distinct immune reconstruction timepoints (2 vs. 7 weeks post-reconstitution), and tumor growth patterns were monitored. Flow cytometry and multiplex immunohistochemical staining were utilized to characterize immunological profiles in peripheral lymphoid organs and tumor microenvironments. Hematoxylin-eosin (HE) staining was employed to assess histomorphological concordance between primary patient tumors and PDX model tissues. Results:HNSCC PDX models were successfully established. NSG mice exhibited a higher and more stable tumor take rate compared to Balb/c nu mice (pilot study: 4/10 vs. 3/10 cases; mean take rate 60%-80% vs. 20%-60 %). The PDX success rate in NSG mice was 46.4% (13/28). In the huHSC-NCG-hIL15 mice model with immune reconstitution at 7 weeks, tumors grew significantly faster, and the PDX modeling process was shorter (617 mm3 at day 70 in 7-week cohort vs.280 mm3 in 2-week cohort). Flow cytometry analysis of the immune microenvironment showed that at 7 weeks of immune reconstitution, the proportions of B cells in the spleen and tumor tissues(2-week vs. 7-week: spleen 16.2% vs. 61.7%, tumor 26.0% vs. 38.8%) and myeloid cells in the spleen (2-week vs. 7-week: spleen 47.2% vs. 88.1 %) were significantly higher, while mice at 2 weeks post-reconstitution showed a higher proportion of T cells (2-week vs. 7-week: spleen 13.2% vs. 9.3%, tumor 4.8% vs. 2.5%). HE results demonstrated that the tumor tissues in PDX models maintained a high degree of morphological similarity to the primary tumors in both NSG and huHSC-NCG-hIL15 mouse models. Conclusion:The HNSCC PDX modeling protocol demonstrates operational feasibility and high reproducibility, establishing this model as a robust platform for mechanistic and immunotherapeutic studies.

Objective To analyze the characteristics of real-world adverse drug events(ADEs)of trabectedin based on the FDA Adverse Event Reporting System(FAERS)database in order to provide references for clinical drug safety management.Methods A total of 1 349 trabectedin-related reports were extracted from the FAERS database from Q1 2007 to Q4 2024.Using the MedDRA coding classification system for system organ class(SOC)and preferred term(PT),signal detection was performed through 4 proportional imbalance methods,including reporting odds ratio(ROR)and proportional reporting ratio(PRR).Subgroup analyses by gender,age,and temporal trends were also conducted.Results Hematological and lymphatic system disorders and hepatobiliary system disorders were the primary SOCs involved.High-frequency PTs included neutropenia(123 cases)and anemia(117 cases).Eight potential ADEs that have not been listed in the drug product instruction were identified.The median onset time of ADEs was 21 d,showing an early failure pattern,with differences observed by gender(females more prone to hematological toxicity)and age(elderly more susceptible to febrile neutropenia).Conclusion Trabectedin requires close attention to hematological toxicity,hepatotoxicity,and newly identified multi-system potential risks.Clinically,monitoring should be strengthened based on time windows and population characteristics to optimize drug regimens.Countermeasure It is recommended to strengthen the full cycle monitoring of anti-tumor drugs,standardize the reporting of adverse reactions,and establish a multi-departmental collaborative research platform.

Objective To investigate the effect of two treatment regimens combining Tacrolimus(TAC)with different Rituximab(RTX)dosages,and to provide clinical reference for treatment strategies.Methods A retrospective analysis was conducted on patients diagnosed with idiopathic membranous nephropathy(IMN)and treated with RTX combined with TAC regimen(RTX+TAC group and low-dose RTX+TAC group)in The First Affiliated Hospital of Xinxiang Medical University.Propensity score matching(PSM)was performed at a 1:1 ratio,and a total of 60 patients were enrolled,with 30 in each group.In low-dose RTX(375 mg/m2 at the first and fifteenth day respectively)+TAC group,if circulating B cells(CD19?)exceeded 5 cells/μL after 3 months,a 200 mg RTX infusion was administered.In RTX(1g at the first and fifteenth day respectively)+TAC group,if complete remission(CR)was not achieved by 6 months,an additional 1000 mg RTX infusion was administered.The incidence of CR,partial remission,and adverse events were followed up for 12 months after medication in both groups.Results(1)Both groups showed significant reductions in 24-hour proteinuria,with the RTX+TAC group demonstrating a notably higher decrease compared to the low-dose RTX+TAC group.Statistical differences were observed between the two groups at the 1st and 3rd months of treatment(P<0.05).Albumin levels gradually increased,and there were differ-ences between the two groups at both the 1st and 3rd months(P<0.05).The anti-phospholipase A2 antibody levels decreased significantly after one month of treatment[3.45(1.90,22.10)vs.3.28(8.30,23.08)RU/mL],P>0.05.At 3 months of treatment,the overall clinical remission rate was 63.3％for the RTX+TAC group compared to 36.7％for the low-dose RTX+TAC group(P<0.05).At 12 months,the RTX+TAC group achieved an overall remission rate of 86.7％,while the low-dose RTX+TAC group reached 83.3％,showing no statistical significance(P>0.05).After one month of treatment,the RTX+TAC group achieved a complete serological immunological remission rate of 33.3％,significantly higher than the 3.3％in the low-dose RTX+TAC group(P<0.05).(2)The cumulative remission rate of the RTX+TAC group was higher than that of the low-dose RTX+TAC group during the first 6 months of follow-up.The remission rate in the low-dose RTX+TAC group increased significantly after 6 months.Log-rank test showed no statistical difference between the survival curves of the two groups(P=0.37).(3)Based on a multifactorial COX regression analysis of factors related to remission in patients with IMN,for every unit increase in serum immunological remission time,the risk of patients achieving remission decreased by 13.5％(HR=0.87,P=0.016).The risk of remission for patients with high titers of anti-PLA2R antibodies decreased by 60.2％(HR=0.39,P=0.018).Conclusions Different RTX dosages yielded comparable overall clinical remission rates without significantly increasing adverse events.RTX+TAC regimen achieves higher early CR rate.Serological remission time and high titer anti-PLA2R antibodies are associated with clinical outcomes.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.
