Central serous chorioretinopathy(CSC)is a macular disease predominantly affecting young to middle-aged adults, characterized by serous retinal detachment in the posterior pole, leading to symptoms such as decreased central vision, visual distortion, and color changes. The disease has a certain degree of self-limitation but can recur. The pathogenesis is still uncertain and the treatment is controversial. Commonly used treatments include medication, retinal laser, photodynamic therapy(PDT)and vitreous anti-vascular endothelial growth factor(VEGF)therapy which have emerged in recent years, but the treatment of recurrent CSC is still tricky. The purpose of this article is to review the current therapeutic approaches regarding CSC, with a view to providing a reference for clinical treatment.

OBJECTIVE To compare the effects of leuprorelin and mifepristone on sex hormone levels， ovarian function， adverse reactions， and recurrence in patients with endometriosis （EMs） after surgery. METHODS A total of 178 patients who underwent surgical treatment for EMs in Ji’an Central People’s Hospital from September 2021 to September 2023 were randomly divided into the leuprorelin group and the mifepristone group， with 92 cases in each group. Medication was initiated on days 1 to 5 of the first menstrual cycle following surgery. Patients in the leuprorelin group received subcutaneous injections of Leuprorelin acetate microspheres， 3.75 mg per time， once every four weeks， for a total of 6 injections. Patients in the mifepristone group took 12.5 mg of Mifepristone capsules orally once daily for six consecutive months. Visual analog scale （VAS）， serum sex hormone levels [follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E2）]， ovarian function indicators [anti- Müllerian hormone （AMH）， antral follicle count （AFC）]， and T helper 1 cell （Th1）/Th2 shift markers [interferon-γ （IFN-γ）， interleukin 2 （IL-2）， IL-4， and IL-10] were compared between the two groups before surgery and after treatment. Incidence and outcome of adverse reactions and recurrence within one year were also compared between the two groups. RESULTS There were no statistically significant differences in baseline indicators between the two groups before surgery （P＞0.05）. After treatment， both groups showed significantly lower VAS scores for chronic pelvic pain， dysmenorrhea and dyspareunia， and significantly reduced serum FSH， LH， E2， IL-4 and IL-10 levels compared to before surgery （P＜0.05）， while serum IFN-γ and IL-2 levels were significantly increased （P＜0.05）； the leuprorelin group showed significantly greater improvements than the mifepristone group in all these indicators （P＜0.05）. After treatment， serum AMH levels in both groups were significantly lower than before surgery levels， while AFC was significantly increased （P＜0.05）； the leuprorelin group had significantly higher serum AMH levels and more AFC compared to the mifepristone group （P＜0.05）. There were no significant differences in the incidence of adverse reactions and outcome rates between the two groups （P＞0.05）. During one year of follow-up after discontinuation， the recurrence rate in the leuprorelin group was significantly lower than in the mifepristone group （1.15% vs. 10.99%， P＜0.05）. CONCLUSIONS Both leuprorelin and mifepristone are effective therapeutic drugs for EMs， but the former has advantages in alleviating pain， regulating serum sex hormone levels， protecting ovarian function， regulating immune function and reducing recurrence rates.

OBJECTIVE To construct three-class （insufficient， normal， excessive） and two-class （insufficient， normal） models for predicting plasma concentration of valproic acid （VPA）， and compare the performance of these two models， with the aim of providing a reference for formulating clinical medication strategies. METHODS The clinical data of 480 patients who received VPA treatment and underwent blood concentration test at the Xi’an International Medical Center Hospital were collected from November 2022 to September 2024 （a total of 695 sets of data）. In this study， predictive models were constructed for target variables of three-class and two-class models. Feature ranking and selection were carried out using XGBoost scores. Twelve different machine learning algorithms were used for training and validation， and the performance of the models was evaluated using three indexes: accuracy， F1 score， and the area under the working characteristic curve of the subject （AUC）. RESULTS XGBoost feature importance scores revealed that in the three-class model， the importance ranking of kidney disease and electrolyte disorders was higher. However， in the two-class model， the importance ranking of these features significantly decreased， suggesting a close association with the excessive blood concentration of VPA. In the three-class model， Random Forest method performed best， with F1 score of 0.704 0 and AUC of 0.519 3 on the test set； while in the two-class model， CatBoost method performed optimally， with F1 score of 0.785 7 and AUC of 0.819 5 on the test set. CONCLUSIONS The constructed three-class model has the ability to predict excessive VPA blood concentration， but its prediction and model generalization abilities are poor； the constructed two-class model can only perform classification prediction for insufficient and normal blood concentration cases， but its model performance is stronger.

OBJECTIVE To evaluate the efficacy and safety of immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy in the treatment of early-stage triple-negative breast cancer （TNBC）. METHODS A systematic search was conducted in PubMed， Embase， Cochrane Library， CNKI， and Wanfang Data to collect randomized controlled trials （RCT） on the use of immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy （experimental group） versus neoadjuvant chemotherapy and adjuvant chemotherapy （control group） in the treatment of TNBC. After literature screening， data extraction and literature quality evaluation， meta-analysis was performed using Stata 17.0. RESULTS A total of 5 RCT involving 1 498 patients were included. The meta-analysis results showed that the pathological complete response rate （pCR） [RR＝1.34， 95%CI （1.09， 1.63）， P＝0.03]， pCR in patients with positive programmed death-1 （PD-1） and its ligand （PD-L1） [RR＝1.33， 95%CI （1.16， 1.51）， P＝0.01]， pCR in patients with positive lymph nodes [RR＝ 1.56， 95%CI （1.27， 1.93）， P＝0.01]， the incidence of grade 3-4 adverse events （AEs） [RR＝1.07， 95%CI （1.01， 1.14）， P＝ 0.04]， the incidence of serious AEs [RR＝1.57， 95%CI （1.31， 1.87）， P＝0.03]， and the incidence of treatment discontinuation due to AEs [RR＝1.45， 95%CI （1.19， 1.76）， P＝0.01] were significantly higher in the experimental group than control group. There were no statistically significant difference in pCR in patients with negative PD-1/PD-L1[RR＝ E-mail：biejun23@126.com 1.26， 95%CI （0.98， 1.62）， P＝0.08] and pCR in patients with negative lymph nodes [RR＝1.14， 95%CI （0.97， 1.33）， P＝0.17] between the two groups. CONCLUSIONS Immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy demonstrates significant efficacy in early-stage TNBC patients， with more pronounced benefits observed in those who are PD-1/PD-L1 positive and lymph node- positive. However， the incidence of AEs is relatively high.

ObjectiveTo investigate the therapeutic efficacy， influencing factors， and safety of a treatment regimen based on coblopasvir hydrochloride capsules/sofosbuvir tablets in patients with chronic hepatitis C virus （HCV） infection in a real-world setting. MethodsA total of 253 patients who attended The Third People’s Hospital of Kunming from September 1， 2021 to May 31， 2024 were enrolled， among whom there were 86 patients with compensated liver cirrhosis （CLC group） and 167 patients with chronic hepatitis C （CHC group）. The patients were treated with coblopasvir hydrochloride capsules （60 mg）/sofosbuvir tablets （400 mg） with or without ribavirin tablets for 12 weeks， and they were followed up for 12 weeks after drug withdrawal. The primary outcome measures were the rate of sustained virologic response at week 12 after treatment （SVR12） and safety， and the secondary outcome measures were the changes in liver function， renal function， blood routine， and liver stiffness measurements （LSM） after 4 weeks of treatment， after 12 weeks of treatment， and at 12 weeks after drug withdrawal. The independent-samples t test and the Mann-Whitney U test were used for comparison of continuous data between two groups， and the Friedman test was used for comparison between multiple groups， while the Bonferroni method was used for paired comparison within each group； the chi-square test was used for comparison of categorical data between two groups. The Logistic analysis was used to investigate related influencing factors. ResultsThe 253 patients with chronic HCV infection had a mean age of 49.38±8.65 years， and there were 151 male patients （59.7%）. Of all patients， 33.99% （86/253） had liver cirrhosis， 25.69% （65/253） had hypertension， 10.67% （27/253） had HIV infection， 8.70% （22/253） had diabetes， 3.95% （10/253） had liver cancer， 1.98% （5/253） had chronic hepatitis B， and 7.91% （20/253） were treatment-experienced patients. As for genotype distribution， 2.77% （7/253） had genotype 1， 12.65% （32/253） had genotype 2， 66.01% （167/253） had genotype 3， 16.60% （42/253） had genotype 6， and 1.98% （5/253） had unknown genotype. The patients had an overall SVR12 rate of 92.09%， with an SVR12 rate of 93.02% in the CLC group and 91.02% in the CHC group. The multivariate logistic regression analysis showed that age （odds ratio ［OR］=1.086， 95% confidence interval ［CI］： 1.007 — 1.170， P=0.032） and HCC （OR=9.178， 95%CI： 1.722 — 48.912， P=0.009） were independent influencing factors for sustained virologic response. Compared with baseline data， the CLC group had significant reductions in alanine aminotransferase （ALT） （χ²=107.103， P0.05）， aspartate aminotransferase （AST） （χ²=90.602， P0.05）， and LSM （χ²=42.235， P0.05） after 12 weeks of treatment， while the CHC group had significant reductions in total bilirubin （χ²=15.113， P0.05）， ALT （χ²=202.237， P0.05）， AST （χ²=161.193， P0.05）， and LSM （χ²=37.606， P0.05）. The incidence rate of serious adverse events was 1.58%， and none of the patients withdrew from drug therapy； the patients with such events were relieved after active symptomatic treatment. The incidence rate of all adverse events was 23.72%， among which fatigue （17.39%） and nausea （2.37%） were the most common adverse events， and these events often disappeared within 2 weeks or were gradually relieved after symptomatic treatment. ConclusionCoblopasvir hydrochloride capsules/sofosbuvir tablets with or without ribavirin tablets has good efficacy and safety in the treatment of chronic HCV infection.
