OBJECTIVE To investigate the clinical effectiveness of triptorelin combined with Biejiajian pill in the treatment of adenomyosis （AM）. METHODS Totally 186 patients with AM admitted to Nanyang First People’s Hospital from January 2022 to October 2024 were selected as subjects and randomized into control group （n＝93） and observation group （n＝93） using the random number table method. Patients in the control group received subcutaneous injections of triptorelin acetate around the umbilicus. In addition to the treatment of control group， patients in the observation group orally administered Biejiajian pill. Both groups underwent treatment for 12 weeks and were followed up for 6 months post-treatment. The clinical efficacy， recurrence and the occurrence of adverse drug reactions were compared between the two groups. Traditional Chinese medicine （TCM） symptoms， endometrial receptivity indicators （endometrial thickness， uterine volume， endometrial resistance index and vascular index）， laboratory indexes （serum luteinizing hormone， follicle stimulating hormone， estradiol， carbohydrate antigen 125， insulin-like growth factor-1， and matrix metalloproteinase 9） were compared between the two groups before and after treatment. RESULTS A total of 164 patients completed the treatment and follow-up， among whom 80 cases were in control group and 84 cases in the observation group. The overall effective rate in the observation group was significantly higher than that in the control group， while the incidence of low estrogen levels and recurrence rate were significantly lower in the observation group compared to the control group （P＜0.05）. There were no statistically significant differences in the incidence of nausea or abnormal liver and kidney function between the two groups （P＞0.05）. After treatment， the pain Visual Analogue Scale scores， Pictorial Blood Loss Assessment Chart， TCM symptoms scores， endometrial thickness， uterine volume， endometrial resistance index， and laboratory indicators in both groups were significantly lower than those before treatment within the same group （P＜0.05）. Moreover， these values were significantly lower in the observation group compared to the control group （except for follicle stimulating hormone） （P＜0.05）. The endometrial vascular index of the two groups was significantly higher than that in the same group before treatment， and the observation group was significantly higher than the control group （P＜0.05）. CONCLUSIONS Triptorelin combined with Biejiajian pill has a definite therapeutic effect on AM， which can effectively improve the degree of dysmenorrhea and menstrual flow， improve endometrial receptivity， lower the recurrence rate in patients， and demonstrate good safety.

OBJECTIVE To observe the clinical efficacy， safety and recurrence of Kuntai capsules combined with Estradiol tablets/Estradiol dydrogesterone tablets in the treatment of diminished ovarian reserve （DOR） as well as their effects on ovarian reserve function， sex hormones， and lymphocyte subsets. METHODS A retrospective analysis was conducted on the clinical data of 165 DOR patients in Nanyang First People’s Hospital. Among them， 80 patients who received Estradiol tablets/Estradiol dydrogesterone tablets （take one tablet per day according to the medication sequence on the instruction） were included in the control group， while 85 patients who additionally took Kuntai capsules （2.0 g per dose， three times daily） were included in the observation group. The treatment duration for both groups was three months. Clinical efficacy， the incidence of adverse drug reaction （ADR）， recurrence rate， and changes in Traditional Chinese Medicine （TCM） syndrome scores， ovarian reserve function indicators [anti-Müllerian hormone （AMH）， inhibin B （INHB）， antral follicle count （AFC）， endometrial thickness， and ovarian volume]， sex hormones [follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E2）]， and T lymphocyte subsets （CD3 +， CD4 +， CD8 +， and CD4 +/CD8 +） were compared before and after treatment. RESULTS The cure and significant improvement rate in the observation group was significantly higher than in the control group （82.35% vs. 65.00%， P＜0.05）. Compared to baseline levels， both groups showed significant reductions in TCM syndrome scores， FSH， LH， CD3+ and CD8+ levels after treatment， while AMH， INHB， E2， CD4 +， CD4 +/CD8 +， AFC， endometrial thickness， and ovarian volume significantly increased （P＜0.05）. The degree of improvement in these indicators was significantly greater in the observation group than in the control group （P＜0.05）. There was no significant difference in the total incidence of ADR between the two groups（P＞ 0.05）. However， the recurrence rate within six months post-treatment was significantly lower in the observation group compared to the control group （5.88% vs. 21.25%， P＜0.05）. CONCLUSIONS Kuntai capsules combined with Estradiol tablets/ Estradiol dydrogesterone tablets have a significant therapeutic effect on DOR， which can improve ovarian reserve function of the patient， regulate sex hormone levels and T lymphocyte subsets， and reduce recurrence rates， with a high safety profile.

Human NAD(P)H: quinone oxidoreductase 1 (NQO1) is a flavoenzyme expressed at high levels in multiple solid tumors, making it an attractive target for anticancer drugs. Bioactivatable drugs targeting NQO1, such as β-lapachone (β-lap), are currently in clinical trials for the treatment of cancer. β-Lap selectively kills NQO1-positive (NQO1⁺) cancer cells by inducing reactive oxygen species (ROS) via catalytic activation of NQO1. In this study, we demonstrated that cryptotanshinone (CTS), a naturally occurring compound, induces NQO1-dependent necrosis without affecting NQO1 activity. CTS selectively kills NQO1⁺ cancer cells by inducing NQO1-dependent necrosis. Interestingly, CTS directly binds to NQO1 but does not activate its catalytic activity. In addition, CTS enables activation of JNK1/2 and PARP, accumulation of iron and Ca²⁺, and depletion of ATP and NAD⁺. Furthermore, CTS selectively suppressed tumor growth in the NQO1⁺ xenograft models, which was reversed by NQO1 inhibitor and NQO1 shRNA. In conclusion, CTS induces NQO1-dependent necrosis via the JNK1/2/iron/PARP/NAD⁺/Ca²⁺ signaling pathway. This study demonstrates the non-enzymatic function of NQO1 in inducing cell death and provides new avenues for the design and development of NQO1-targeted anticancer drugs.

Objective To address the current blind spots in quality control and the risk of data distortion in radiological health technical service institutions, overcome the limitations of low efficiency and insufficient anomaly identification in manual verification, establish an automatic anomaly early warning mechanism based on AI algorithms, provide accurate clues for health supervision and law enforcement, and significantly enhance the efficiency of industry supervision. Methods On-site inspection data were collected via photographic imaging. Advanced image processing and object detection algorithms were employed to automatically extract and analyze key information from the images. Through data analysis, the system was used to calculate and assess the inspection results. A dynamic early warning engine was developed to automatically trigger alerts upon detection of deviations from standard thresholds or regulatory violations in radiological health technical services. These alerts were delivered through a regulatory information system. Results Following AI model training, the accuracy of the image processing and object detection algorithms reached 99% and the early warning accuracy reached 93%. Compared with the traditional supervision mode, the efficiency of anomaly detection was improved and the average response time was shortened. Conclusion The full-process supervision information system constructed in this study has realized the triple mechanism of pre-event standardization, in-event monitoring, and post-event traceability for radiological health technical services. In particular, the system has established a four-level quality control chain of “institutional self-inspection, intelligent recheck, expert judgment, and administrative action”, providing a technological innovation path for ensuring the radiation protection and safety of medical staff, patients, and the public.

OBJECTIVE To assess the correlation between the steady-state minimal concentration （cmin） and 24 h area under the drug concentration-time curve （AUC24）/minimal inhibitory concentration （MIC） ratio （AUC24/MIC） of vancomycin in pediatric patients， and analyze independent risk factors for treatment failure. METHODS Data of hospitalized children treated with vancomycin and receiving therapeutic drug monitoring in our hospital from January 2021 to July 2024 were retrospectively collected and divided into success group and failure group according to whether the treatment was successful or not. Spearman correlation analysis was used to analyze the correlation between cmin and AUC24/MIC of vancomycin， and one-way and multifactorial Logistic regression analyses were used to screen the independent risk factors for vancomycin treatment failure. RESULTS A total of 59 children were included， with 41 in the success group and 18 in the failure group. Compared with the failure group， AUC24/MIC of vancomycin was significantly higher in the success group （P＝0.038）， but there was no statistically significant difference in the cmin of the two groups （P＞0.05）； cmin of vancomycin was significantly positively correlated with AUC24/MIC （r＝0.499， P＜0.001）， but it has a certain efficacy in predicting the achievement of the AUC24/MIC standard （≥400） （area under the receiver operator characteristic curve＝0.696）， with an optimal cutoff value of 6.05 mg/L determined by the Youden index. The efficacy of AUC24/ MIC in predicting treatment failure was superior to cmin （areas under the receiver operator characteristic curve were 0.671 vs. 0.523， P were 0.038 vs. 0.684）， with higher sensitivity （83.3% vs. 66.7%）. Hypoproteinemia and AUC24/MIC≤369.1 were independent risk factors for vancomycin treatment failure （P＜0.05）. The incidence of nephrotoxicity was 3.4%. CONCLUSIONS There is a significant positive correlation between cmin and AUC24/MIC of vancomycin in pediatric patients； hypoproteinemia and AUC24/MIC≤369.1 are independent risk factors for vancomycin treatment failure in children.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

Objective:To investigate the application effects of learning pyramid theory combined with constructivism in the standardized training of nurses in the department of gastroenterology.Methods:We randomly divided 104 gastroenterology nurses who received standardized training from October 2021 to October 2023 into observation group and control group, with 52 nurses in each group. The control group received conventional teaching, while the observation group received a combination of learning pyramid theory and constructivist teaching. The two groups were compared in terms of theoretical and practical scores, core competencies, self-learning abilities, and professional values scores before and after training. SPSS 23.0 was used to perform the t-test. Results:After training, the two groups showed improvements in all the tests; and the scores were all significantly higher in the observation group than in the control group: theoretical knowledge [(88.61±15.62) vs. (81.76±14.27)], skill practice [(82.91±15.17) vs. (76.40±13.82)], Competency Inventory for Registered Nurses scale score [(157.83±21.73) vs. (125.40±15.77)], self-learning ability score [(123.38±21.62) vs. (97.43±15.23)], and Nurse Professional Values scale score [(89.15±14.63) vs. (78.52±12.84)].Conclusions:The teaching model of learning pyramid theory and constructivism theory can enhance standardized training effectiveness for gastroenterology nurses.

Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.
