OBJECTIVE To systematically evaluate the methodological quality of the postoperative chemotherapy guidelines/ consensuses for ovarian epithelial tumor. METHODS A search was conducted across databases including PubMed， Embase， Web of Science， CBM， VIP， Chinese Medical Journal Data， Wanfang Data， and CNKI， as well as the official websites of GIN， NICE， Medlive， AHRQ， CSCO， ASCO， and NCCN. The search period was from the establishment of the databases/websites to March 10， 2025. The quality of the included guidelines/consensus was evaluated by using the AGREE-Ⅱ tool. RESULTS A total of 16 guidelines/consensuses were included. The domain scores of AGREE-Ⅱ evaluation were as follows： scope and purpose of 85.07%， participants of 47.92%， rigor of development of 57.49%， clarity of presentation of 88.02%， applicability of 8.20%， and independence of 53.39%. Among them， 14 were recommended at grade B and 2 were recommended at grade C. The subgroup analysis by different countries/regions and different types of studies showed that the scores for participants， rigor of development， and independence of the guidelines/consensuses in China were significantly lower than foreign countries （P＜0.05）； the scores for participants and rigor of development of the guidelines were significantly higher than consensuses （P＜0.05）. The guideline/ consensus recommendation results indicated that grade B guidelines/consensus recommend platinum-based combination chemotherapy as the preferred adjuvant chemotherapy regimen for stage Ⅰ high-grade serous carcinoma patients；platinum-based combination chemotherapy±bevacizumab was recommended as the preferred adjuvant chemotherapy regimen for stage Ⅱ-Ⅳ high- grade serous carcinoma patients and for platinum-sensitive recurrent high-grade serous carcinoma patients； non-platinum single- agent chemotherapy±bevacizumab was recommended as the preferred chemotherapy regimen for platinum-resistant recurrent high- grade serous carcinoma patients. CONCLUSIONS The overall quality of postoperative chemotherapy guidelines/consensuses for ovarian epithelial tumor is not high. The methodological quality of guidelines/consensuses in China is still lagging behind that of foreign countries. The recommendations differ from those in foreign countries. It is recommended to improve the aspects of participants， rigor of development， and independence， to recommend treatment plans based on the different stages of ovarian cancer， and develop guidelines/consensuses that align with China’s national conditions.

Through collecting the existing clinical evidences on acupuncture and moxibustion for urticaria, the distribution of evidence in this field was mapped. A systematic search of Chinese and English literature was conducted in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library for treatment of urticaria with acupuncture and moxibustion, published up to December 31, 2023 since inception of each database. The research status in this field was summarized using an evidence mapping approach, and methodological quality was assessed. A total of 323 randomized controlled trials (RCTs) and 22 systematic reviews were included. The number of studies on acupuncture and moxibustion for urticaria has been increasing, with a significant rise in recent years. In most RCTs, the study scale was small, and the subjects focused on chronic spontaneous urticaria in adolescents and middle-aged adults, aged 14 to 60 years. Regarding the intervention measures, the single therapy of acupuncture and moxibustion was predominant such as acupoint injection, acupoint embedding thread, and filiform needling. In acupuncture with filiform needles, the commonly used acupoints were Quchi (LI11), Xuehai (SP10), Sanyinjiao (SP6), Zusanli (ST36) and Hegu (LI4). The main outcome measures referred to effectiveness rate, score of disease severity, recurrence rate, laboratory indexes, and score of quality of life; and the short-term effect was evaluated specifically. The overall methodological quality of the included studies was relatively low. It is suggested that the future research should focus on large-scale, multi-center, high-quality clinical trials, optimize the protocols for acupuncture and moxibustion intervention, standardize the outcomes, and draw the attention to the evaluation of long-term efficacy, so as to provide clinical evidences of high certainty for urticaria treated with acupuncture and moxibustion.

OBJECTIVE: To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease. METHODS: The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points. RESULTS: The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower. CONCLUSION It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

Objective:To evaluate the diagnostic efficacy of 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT in patients with prostate imaging reporting and data system (PI-RADS) 1-3 lesions on multi-parametric MRI (mpMRI) and pathologically confirmed prostate cancer. Methods:Clinical, pathological, and imaging data of 59 patients (age (67.8±7.6) years) with PI-RADS 1-3 lesions on mpMRI in the First Affiliated Hospital of Xi′an Jiaotong University between December 2021 and March 2024 were retrospectively collected. Those patients also underwent 18F-PSMA-1007 PET/CT and prostate biopsy during the same period due to an elevated prostate specific antigen (PSA) level. The diagnostic performances of 18F-PSMA-1007 PET/CT for PI-RADS 1-3 prostate cancer and clinically significant prostate cancer were evaluated by using pathological results as the standard. Mann-Whitney U test was used to compare differences in clinical characteristics and PET parameters between PET-positive and PET-negative groups, and logistic regression analysis was performed to select independent influencing factors for the PET/CT diagnosis of prostate cancer. Results:Of the included 59 patients, 7, 27, and 25 had PI-RADS scores of 1, 2, and 3 respectively. Benign prostate hyperplasia was pathologically confirmed in 8 patients, and prostate cancer was confirmed in 51 patients, of which 37 had clinically significant prostate cancer. The sensitivity of 18F-PSMA-1007 PET/CT in diagnosing prostate cancer was 86.3%(44/51), the specificity was 2/8, the accuracy was 78.0%(46/59), the positive predictive value was 88.0%(44/50), and the negative predictive value was 2/9. For patients with clinically significant prostate cancer, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were 91.9%(34/37), 27.3%(6/22), 67.8%(40/59), 68.0%(34/50), and 6/9, respectively. SUV max was significantly higher in the PET-positive group ( n=44) than that in the PET-negative group ( n=7; 12.8(9.1, 23.5) vs 5.1(5.0, 6.2); Z=-4.16, P=0.001). Logistic regression analysis showed that SUV max was an independent influencing factor for the diagnosis of prostate cancer by 18F-PSMA-1007 PET/CT (odds ratio ( OR)=6.01, 95% CI: 1.57-23.00, P=0.009). Conclusions:18F-PSMA-1007 PET/CT has a high sensitivity and positive predictive value in prostate cancer patients with PI-RADS 1-3 on mpMRI. It can be used as a supplementary modality to mpMRI to guide clinical decision for patients with PI-RADS 1-3 and clinically suspected prostate cancer lesions.

Objective:To evaluate the safety and efficacy of accelerator-based boron neutron capture therapy (AB-BNCT) in the treatment of recurrent and refractory malignant tumors.Methods:The data of 14 patients admitted to Xiamen Humanity Hospital from September 2022 to April 2023 were prospectively collected, including 7 patients with primary brain malignancies and 7 patients with locally recurrent inoperable head and neck malignancies. All patients received intravenous infusion of boron drug (NBB-001, p-dihydroxyborylphe nylalanine, a patented freeze-dried formulation) at a total nominal dosage of 500 mg/kg (11 patients) or 750 mg/kg (3 patients), and were irradiated with neutrons (operating with NeuPex system). Adverse events after treatment were recorded and assessed. The primary efficacy endpoint was the 90 d objective response rate (ORR), while the secondary endpoints included progression-free survival (PFS) and complete response rate (CRR). Data were compiled and analyzed by SAS 9.4 software. The rate and 95% CI were calculated using Clopper-Pearson method. Results:The median dose delivered to 80% of the target volume (D 80%) was 16.80 GyE (range: 8.93-23.79 GyE). The most common adverse reactions were hyperamylasemia, alopecia, and hyperprolactinemia. Five patients experienced 8 cases of grade 3 or above adverse events, including 1 case of grade 4 acute kidney injury and 7 cases of grade 3 adverse events. All adverse events were recovered after observation or treatment. At 90 d after treatment, the ORR of all patients was 9/14 (64%, 95% CI: 35%-87%), disease control rate (DCR) was 10/14 (71%, 95% CI: 42%-92%), CRR was 2/14 (14%, 95% CI: 2%-42%); and the best overall response during the entire course included an ORR of 10/14 (71% ,95% CI: 42%-92%), DCR of 13/14 (93%, 95% CI: 66%-100%), and CRR of 3/14 (21% ,95% CI: 5%-51%). The 1-year survival rate for head and neck malignancies was 71.4%, and the 2-year survival rate was 42.8%. The 1-year survival rate for recurrent brain malignancies was 42.8%. Conclusion:AB-BNCT demonstrates favorable safety and promising efficacy in treating primary brain malignancies and recurrent/refractory head and neck malignancies, representing a potential therapeutic option.

Objective To construct a radiomics model to improve the discriminatory ability of 18 F-PSMA-1007 PET/CT for focal prostate cancer.Methods We retrospectively collected data from 74 patients diagnosed with prostate cancer by biopsy at The First Affiliated Hospital of Xi'an Jiaotong University between July 2020 and April 2024.These patients had focal radionuclide accumulation observed on 18F-PSMA-1007 PET/CT,with the median age of 71 years.Among them,42 patients had a Gleason score＜8 and 32 patients had a Gleason score ≥8.An external validation set was randomly selected based on the timing of examination,while the remaining patients were randomly divided into training and test sets at a 7∶3 ratio.Region of interest(ROI)were semi-automatically drawn on registered images,manually adjusted,and symmetrically shifted to contralateral non-tumor tissue.We made variance and correlation analyses to choose features,and built models with Logistic regression and compared the results with those of visual evaluation.Receiver operating characteristics(ROC)curves were drawn to compare model performance,and subgroup analysis was performed to identify optimal features for distinguishing tumor tissue,based on Gleason score,serum total prostate specific antigen(tPSA)levels,and lesion location.Results A total of eight features were selected.The area under the curve(AUC)for visual evaluation,testing set,and external validation set were 0.858,0.933,and 0.891,respectively.The sensitivity was 0.757,0.800 and 0.917;the specificity was 0.960,0.800 and 0.792,respectively.Subgroup analysis showed that the radiomic features 10percentile and skewness had a high value in tumor differentiation.In tumor tissues,the 10percentile values were higher than in non-tumor tissues across all groups(P-values were 0.012,0.002,＜0.001,＜0.001,＜0.001,and＜0.001).When tPSA≤10 ng/mL and Gleason score ≥8,there was no statistically significant difference in skewness between tumor and non-tumor tissues(P=0.08).When tPSA ≥20 ng/mL,the skewness of non-tumor tissue was slightly higher than that of tumor tissue,but the difference was not statistically significant(P-values were 0.285 and 0.791).When the tumor was located in the posterior part of the prostate(left posterior and right posterior),the skewness was significantly higher in tumor tissue than in non-tumor tissue(P-values＜0.001 for both).Conclusion The radiomics model had better sensitivity and accuracy than visual evaluation in distinguishing focal prostate cancer tumors from non-tumor tissues,but visual evaluation had higher specificity.Skewness and 10percentile had a high value in differential diagnosis.

Neurogenic bladder(NB)is one of the most challenging urinary system disorders,with spinal cord injury(SCI)being an important etiological factor.Animal models provide crucial tools for investigating the pathogenesis,therapeutic strategies,and novel drug screening for NB subsequent to SCI.We reviewed and synthesized recent literature on NB animal models after SCI from both domestic and international sources.This review summarizes and analyzes research advancements using these models in terms of animal species,SCI segments,modeling techniques,and evaluation indicators,with the aim of offering insights and guidance for future experimental research based on animal models of NB following SCI.

The central amygdala (CeA) is a crucial modulator of emotional, behavioral, and autonomic functions, including cardiovascular responses. Despite its importance, the specific circuit by which the CeA modulates blood pressure remains insufficiently explored. Our investigations demonstrate that photostimulation of GABAergic neurons in the centromedial amygdala (CeM^GABA), as opposed to those in the centrolateral amygdala (CeL), produces a depressor response in both anesthetized and freely-moving mice. In addition, activation of CeM^GABA axonal terminals projecting to the nucleus tractus solitarius (NTS) significantly reduces blood pressure. These CeM^GABA neurons form synaptic connections with NTS neurons, allowing for the modulation of cardiovascular responses by influencing the caudal or rostral ventrolateral medulla. Furthermore, CeM^GABA neurons targeting the NTS receive dense inputs from the CeL. Consequently, stimulation of CeM^GABA neurons elicits hypotension through the CeM-NTS circuit, offering deeper insights into the cardiovascular responses associated with emotions and behaviors.

Complement C3 plays a critical role in periodontitis. However, its source, role and underlying mechanisms remain unclear. In our study, by analyzing single-cell sequencing data from mouse model of periodontitis, we identified that C3 is primarily derived from periodontal fibroblasts. Subsequently, we demonstrated that C3a has a detrimental effect in ligature-induced periodontitis. C3ar^-/- mice exhibited significantly less destruction of periodontal support tissues compared to wild-type mice, characterized by mild gingival tissue damage and reduced alveolar bone loss. This reduction was associated with decreased production of pro-inflammatory mediators and reduced osteoclast infiltration in the periodontal tissues. Mechanistic studies suggested that C3a could promote macrophage polarization and osteoclast differentiation. Finally, by analyzing single-cell sequencing data from the periodontal tissues of patients with periodontitis, we found that the results observed in mice were consistent with human data. Therefore, our findings clearly demonstrate the destructive role of fibroblast-derived C3 in ligature-induced periodontitis, driven by macrophage M1 polarization and osteoclast differentiation. These data strongly support the feasibility of C3a-targeted interventions for the treatment of human periodontitis.
