Objective To evaluate the effect of a multidisciplinary collaborative quality control management (hereinafter referred to as "QC management") on improving the performance of biological safety cabinets in hospital. Methods A total of 63 ClassⅡbiological safety cabinets in active use at Peking University Third Hospital were selected as the study subjects using the before-after study mode. Conventional management was implemented on the biological safety cabinets from 2018 to 2021. QC management was used in 2022. The compliance of biological safety cabinets management norm and performance differences under the two models were compared. Results The median and the 25th and 75th percentiles [M(P25, P75)] of the service life among these 63 biological safety cabinets were 3 (1,6) years. The overall performance pass rate and inflow velocity pass rate of biological safety cabinets were higher in the QC management than that in the conventional management (90.5% vs 65.1%, 96.8% vs 84.1%, both P<0.05). However, there was no significant difference in downflow velocity, high-efficiency particulate air filter integrity, cleanliness, airflow smoke pattern, noise, and illumination pass rates of biosafety cabinets before and after the implementation of QC management (79.4% vs 88.9%, 90.5% vs 100.0%, 96.8% vs 100.0%, 85.7% vs 100.0%, 100.0% vs 100.0%, and 85.7% vs 96.8%, respectively; all P>0.05). Conclusion sQC management improves the standardization of biological safety cabinet management and key performance indicators in hospital.

ObjectiveTo evaluate the clinical efficacy and safety of the traditional Chinese medicine (TCM) compound Chaiqin Xiaoyong Decoction (柴芩消痈饮, CXD) combined with Jinhuang Ointment (金黄膏, JO) in treating the nodular stage of acne mastitis of liver meridian heat accumulation type. MethodsA randomized, double-blind, placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group, with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours, along with standard nursing care. On this basis, the treatment group received oral CXD granules, while the control group received placebo granules, administered twice daily, 3 sachets per dose, for 14 consecutive days. Clinical efficacy, TCM symptom scores, nodule size, visual analogue scale (VAS) pain scores, white blood cell (WBC) count, C-reactive protein (CRP) level, and systemic immune-inflammation index (SII) were compared. At the end of treatment, efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% (47/52), significantly higher than 32.00% (16/50) in the control group (P<0.01). The treatment group also showed significantly lower TCM symptom scores, VAS scores, nodule size, WBC count, CRP level, and SII (P<0.05 or P<0.01). During follow-up, the surgical intervention rate in the treatment group was 5.77% (3/52), lower than 14.00% (7/50) in the control group, with a statistically significant difference (P<0.01). No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type, improves TCM symptom scores, enhances overall clinical efficacy, and demonstrates good safety.

ObjectiveTo evaluate the efficacy of Shuanghua drink in treating primary dysmenorrhea in the rat model and explore its mechanism of action. MethodsAn oxytocin-induced writhing mouse model was established to evaluate the analgesic effect of Shuanghua drink. Forty-eight non-pregnant female institute of cancer research (ICR) mice were randomly divided into six groups, including a blank group, a model group, an ibuprofen group (85.00 mg·kg-1), a low-dose group of Shuanghua drink (7.14 mL·kg-1), a medium-dose group of Shuanghua drink (14.28 mL·kg-1), and a high-dose group of Shuanghua drink (28.57 mL·kg-1). Each group consisted of eight mice. All treatment groups received daily intragastric administration at corresponding doses for 10 consecutive days. One hour after the final administration, 2 U of oxytocin was intraperitoneally injected per mouse. The writhing latency and number of writhing within 20 minutes were recorded. A primary dysmenorrhea rat model was established by using estradiol benzoate and oxytocin to evaluate the inhibitory effect of Shuanghua drink on the contraction of uterine smooth muscle. Forty-eight non-pregnant female Sprague-Dawley (SD) rats were divided into six groups, including a blank group, a model group, an ibuprofen group (51.00 mg·kg-1), a low-dose group of Shuanghua drink (4.28 mL·kg-1), a medium-dose group of Shuanghua drink (8.57 mL·kg-1), and a high-dose group of Shuanghua drink (17.10 mL·kg-1). Each group consisted of eight rats. Rats received subcutaneous injections of estradiol benzoate for 10 consecutive days to enhance uterine sensitivity. On the eleventh day, oxytocin (2 U/rat) was intraperitoneally administered to induce abnormal uterine contractions for establishing the primary dysmenorrhea model. All treatment groups received daily intragastric administration from the second day of modeling for 10 days. The effects of Shuanghua drink were evaluated by using parameters including uterine motility and the variation rate of uterine motility. The mechanism of action was investigated in rats with primary dysmenorrhea. The content of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2), thromboxane B2 (TXB2), prostacyclin metabolite (6-keto-PGF1α), and β-endorphin (β-EP) in uterine tissue of rats was detected by using enzyme-linked immunosorbent assay (ELISA). The changes in the content of nitric oxide (NO) and inducible nitric oxide synthase (iNOS) were analyzed via colorimetric assay. Western blot was performed to determine the content of phosphorylated inhibitor of kappa B kinase beta (p-IKKβ)/IKKβ, phosphorylated inhibitor of kappa B alpha (p-IκBα), IκBα, phosphorylated p65 (p-p65), p65, and cyclooxygenase-2 (COX-2) proteins in uterine tissue of rats. ResultsIn the oxytocin-induced writhing mouse model, the model group exhibited significantly shortened writhing latency and increased writhing frequency compared to the control group (P<0.01). Both the ibuprofen group and the high-dose group of Shuanghua drink displayed prolonged writhing latency (P<0.05), while the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink exhibited reduced writhing frequency (P<0.01). In the primary dysmenorrhea rat model, the uterine motility and its variation rate in the model group were significantly higher than those in the blank group (P<0.01). These parameters were markedly suppressed by ibuprofen and Shuanghua drink at all tested doses (P<0.01). For the mechanism of action, the model group showed significantly increased PGF2α/PGE2, TXB2/6-keto-PGF1α, NO, and iNOS in uterine tissue (P<0.05, P<0.01) and significantly decreased β-EP (P<0.01). These parameters were significantly attenuated in the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink. The PGF2α/PGE2 (P<0.01), TXB2/6-keto-PGF1α (P<0.01), NO (medium-dose group P<0.05), and iNOS (P<0.01) were reduced, and the β-EP (medium-dose group P<0.05) was up-regulated. Compared to the model group, the ibuprofen group and medium-dose group of Shuanghua drink showed significantly increased content of β-EP in the serum of rats (P<0.05). Compared to the blank group, the model group showed significantly elevated expressions of COX-2, p-IKKβ/IKKβ, p-IκBα/IκBα, and p-p65/p65 proteins (P<0.01) and significantly reduced anti-inflammatory protein IκBα (P<0.05). Compared to the model group, the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink showed significantly reduced expressions of COX-2 (P<0.01), p-IKKβ/IKKβ (P<0.01), p-IκBα/IκBα (P<0.05, P<0.01), and p-p65/p65(P<0.01) and up-regulated expression of IκBα protein (P<0.05, P<0.01). ConclusionShuanghua drink effectively alleviates primary dysmenorrhea through analgesia and suppression of abnormal contractions of uterine smooth muscle. Its mechanism may be mediated by reduced levels of PGF2α/PGE2, TXB2/6-keto-PGF1α, iNOS, and NO, elevated β-EP level, and inhibited COX-2/NF-κB signaling pathway.

Objective:To explore the clinical efficacy of olapalib in the treatment of platinum-sensitive recurrent breast cancer susceptibility gene (BRCA)-mutated ovarian cancer.Methods:The clinical data of 105 patients with platinum-sensitive recurrent BRCA-mutated ovarian cancer confirmed by pathology/imaging from October 2020 to March 2023 in Baoding Second Central Hospital were selected retrospectively, and they were divided into the control group (52 cases) and the experimental group (53 cases) according to the treatment methods. The control group was treated with a platinum-containing regimen, followed by olaparib at the end of the treatment. The experimental group was treated with olaparib. The recent clinical outcomes, tumour marker levels, ovarian cancer functional assessment of treatment questionnaire (FACT-O) score, cancer fatigue scale (CFS) score, and adverse reaction were compared between the two groups. The survival curve was drawn by Kaplan-Meier, and the prognosis was compared.Results:The overall response rate clinical in the experimental group was higher than that in the control group: 64.15%(34/53) vs.44.23%(23/52), there was a statistical difference ( χ2 = 4.20, P<0.05). After treatment, the levels of serum glycoantigen (CA) 125, CA153, human epithelial protein 4 (HE4), and vascular endothelial growth factor (VEGF) in the experimental group were lower than those in the control group: (42.35 ± 6.85) kU/L vs. (46.64 ± 7.11) kU/L, (24.26 ± 4.58) kU/L vs. (26.74 ± 5.20) kU/L, (144.25 ± 19.85) pmol/L vs. (155.64 ± 21.26) pmol/L, (335.32 ± 38.41) μg/L vs. (359.47 ± 41.24) μg/L; the FACT-O scores in the experimental group was higher than that in the control group: (55.24 ± 6.85)scores vs. (51.26 ± 7.19) scores; the CFS scores in the experimental group was lower than that in the control group: (38.51 ± 6.11) scores vs. (44.94 ± 8.38) scores, there were statistical differences ( P<0.05).After treatment, the rate of dizziness, nausea, leukopenia, neutropenia, thrombocytopenia, and anemia in the experimental group were lower than those in the control group ( P<0.05). The results of the survival curve showed that the median progression-free survival in the experimental group was longer than that in the control group ( P<0.05). Conclusions:Single-agent olaparib is effective in treating platinum-sensitive recurrent BRCA-mutated ovarian cancer, and can improve quality of life, reduce anemia and adverse reaction, and prolong patients′ median survival.

Objective:To Explore the changes of annexin A2 and vascular endothelial cadherin (VE-Cad) in patients with cerebral infarction (CI) undergoing emergency thrombolysis, and analyze their relationship with progression within 10 d.Methods:Using a prospective research method, 78 patients with CI were selected from October 2019 to June 2022 in Xi'an International Medical Center Hospital, and all patients were treated with emergency thrombolysis. The serum levels of annexin A2 and VE-Cad before and after thrombolysis were measured by enzyme-linked immunosorbent assay, and the National Institute stroke scale (NIHSS) was used to assess patients' neurologic impairment. The baseline data, imaging findings at admission and routine laboratory examination indexes were recorded. The progression within 10 d after thrombolysis was recorded. Pearson correlation analysis was used to analyze the correlation between annexin A2, VE-Cad and NIHSS score. Multivariate Logistic regression was used to analyze the independent risk factors of progression within 10 d after thrombolysis in patients with CI. The value of annexin A2 and VE-Cad in predicting the progression within 10 d after thrombolysis in patients with CI was evaluated by the receiver operating characteristics (ROC) curve. A restricted cubic spline model was drawn to evaluate the dose-response relationship between annexin A2, VE-Cad and the progression within 10 d after thrombolysis in patients with CI.Results:Compared with before thrombolysis, the annexin A2 after thrombolysis was significantly higher: (24.50 ± 3.27) μg/L vs. (20.86 ± 3.84) μg/L, the VE-Cad and NIHSS score were significantly lower: (4.72 ± 1.05) mg/L vs. (6.81 ± 1.31) mg/L and (8.64 ± 2.35) scores vs. (13.01 ± 2.86) scores, and there were statistical differences ( P<0.01). Before and after thrombolysis, Pearson correlation analysis result showed there was a negative correlation between annexin A2 and NIHSS score ( r =-0.796 and - 0.568, P<0.01), and a positive correlation between VE-Cad and NIHSS score ( r = 0.820 and 0.502, P<0.01). Among 78 patients with CI treated with emergency thrombolysis, 7 cases (8.97%) experienced progression within 10 d. There were statistical differences in hypertension, diabetes, hyperlipidemia, onset to thrombolysis time, infarct site, systolic blood pressure, triacylglycerol, high-density lipoprotein cholesterol, and the NIHSS score, annexin A2, VE-Cad before and after thrombolysis between patients with progression within 10 d after thrombolysis and patients without progression within 10 d after thrombolysis ( P<0.05 or <0.01); there were no statistical differences in gender composition, age, body mass index, coronary heart disease, atrial fibrillation, smoking, alcohol consumption, family history of stroke, carotid plaques, blood glucose, diastolic blood pressure, white blood cell count, platelet count, total cholesterol low-density lipoprotein cholesterol between the two groups ( P>0.05). After adjusting for hypertension, diabetes and hyperlipidemia, multivariate Logistic regression analysis result showed that the infarction site, onset to thrombolysis time, VE-Cad after thrombolysis and annexin A2 after thrombolysis were still independent factors of progression within 10 d after thrombolysis in patients with CI ( OR = 2.570, 2.496, 3.147 and 0.352; 95% CI 1.285 to 5.139, 1.303 to 4.781, 1.629 to 6.080 and 0.158 to 0.782; P<0.05 or <0.01). ROC curve analysis results showed that the area under the curve of annexin A2 combined with VE-Cad after thrombolysis to predict the progression within 10 d after thrombolysis in patients with CI was significantly larger than that of annexin A2 and VE-Cad after thrombolysis alone (0.898 vs. 0.822 and 0.799, χ2 = 2.17 and 1.98, P = 0.039 and 0.048). The optimal cutoff values of annexin A2 and VE-Cad after thrombolysis were <23.27 μg/L and >4.92 mg/L, with a sensitivity of 88.24%, and a specificity of 77.05%. The restricted cubic spline analysis result showed that the continuous changes in annexin A2 after thrombolysis were roughly negatively correlated with the progression within 10 d after thrombolysis in patients with CI ( OR = 0.720, 95% CI 0.561 to 0.930, P = 0.010), the continuous changes in VE-Cad after thrombolysis were roughly positively correlated with the progression within 10 d after thrombolysis in patients with CI ( OR = 1.450, 95% CI 1.126 to 1.188, P = 0.004). When annexin A2<23.80 ng/L and VE-Cad>5.25 mg/L after thrombolysis, the risk of progression within 10 d after thrombolysis in patients with CI significantly increased. Conclusions:The expression of annexin A2 increases and VE-Cad decreases after emergency thrombolysis in patients with CI, and the expression levels of both are closely related to the degree of neurologic impairment, and the risk of progression within 10 d after thrombolysis could be determined clinically by detecting their changes.

OBJECTIVES:
In recent years, the incidence and detection rate of pancreatic cystic lesions (PCLs) have increased significantly. Endoscopic ultrasound (EUS) plays an indispensable role in the diagnosis and differential diagnosis of PCLs. However, evidence comparing the diagnostic performance of EUS-guided fine-needle aspiration (EUS-FNA) and fine-needle biopsy (FNB) remains limited. This study aims to compare the diagnostic yield, adequacy of tissue acquisition, and safety between EUS-FNA and EUS-FNB in evaluating PCLs to inform clinical practice.
METHODS:
A retrospective review was conducted on patients with PCLs who underwent either EUS-FNA or EUS-FNB between January 2014 and August 2021. The diagnostic yield, tissue acquisition adequacy, and incidence of adverse events were compared between the 2 groups.
RESULTS:
A total of 90 patients with PCLs were included (52 in the FNA group and 38 in the FNB group). The diagnostic yield was similar between the FNA and FNB groups (94.2% vs 94.7%, P>0.05). The adequacy of tissue acquisition was 71.2% in the FNA group and 81.6% in the FNB group (P>0.05). No statistically significant difference was observed in the incidence of adverse events between the 2 groups (P>0.05).
CONCLUSIONS
Both EUS-FNA and EUS-FNB demonstrate equally high diagnostic yields and tissue adequacy in PCLs, with excellent safety profiles. Both methods are safe and effective diagnostic tools for evaluating PCLs.

Recent Advances in Ophthalmology 2025;45(4):326-336
Retinal detachment(RD)is defined as a separation between the neuroepithelial layer and the pigment epi-thelial layer of the retina,which is a serious ophthalmologic emergency that,if left untreated,may lead to permanent vision loss.Thus,the study of its treatment is of great importance.Current treatments include laser photocoagulation,pneumatic retinal fixation,scleral buckling,and vitrectomy,etc.With the advancement of minimally invasive surgical techniques,minimally invasive vitrectomy has become an important treatment.The development of smaller-diameter instruments such as 23 G,25 G,and 27 G has helped reduce surgical trauma by decreasing the size of the surgical incision in minimally inva-sive surgeries,improving surgical safety and effectiveness.At the same time,tissue engineering has emerged as a promising technique in retinal repair,especially in the application of biomaterials and the research of cell therapy.Although research-ers have achieved promising results currently,there are still some challenges,such as the biocompatibility of biomaterials,the effectiveness of cell therapy,and the evaluation of long-term efficacy.Therefore,the purpose of this article is to review the current status of the application of minimally invasive techniques and tissue engineering in the treatment of retinal de-tachment,to discuss their potential advantages,limitations,and trends in their integration,and to look into the future di-rection of development to provide guidance for clinical practice.
