ObjectiveTo explore the clinical efficacy and mechanism of Bupi Qingfei prescription （BPQF） in treating stable bronchiectasis in the patients with syndromes of lung-spleen Qi deficiency and phlegm-heat accumulation in the lungs. MethodsA randomized， double-blind， placebo-controlled trial was conducted. Patients were randomized into BPQF and placebo control （PC） groups. On the basis of conventional Western medicine treatment， the BPQF granules and placebo were respectively administered at 10 g each time， twice a day， for a course of 24 weeks. The TCM symptom scores， Quality of Life Questionnaire for Bronchiectasis （QOL-B） scores， lung function indicators， T lymphocyte subsets， level of inflammatory factors in the sputum， level of neutrophil elastase （NE） in the sputum， and occurrence of adverse reactions were observed before and after treatment in the two groups. ResultsA total of 64 patients completed the study， encompassing 32 in the BPQF group and 32 in the PC group. After treatment， the BPQF group showed decreased TCM symptom scores （P<0.01）， increased QOL-B scores （P<0.01）， and declined levels of tumor necrosis factor （TNF）-α and NE （P<0.05， P<0.01）. The PC group showed decreased TCM symptom （except spleen deficiency） scores （P<0.01）， increased the QOL-B health cognition and respiratory symptom domain scores （P<0.05， P<0.01）， and a declined TNF-α level （P<0.01）. Moreover， the BPQF group had lower TCM symptom （except chest tightness） scores （P<0.05， P<0.01）， higher QOL-B （except treatment burden） scores （P<0.05， P<0.01）， and lower levels of interleukin-6 and TNF-α （P<0.05） than the PC group. Neither group showed serious adverse reactions during the treatment process. ConclusionBPQF can ameliorate the clinical symptoms of stable bronchiectasis patients who have lung-spleen Qi deficiency or phlegm-heat accumulation in the lungs by regulating the immune balance and inhibiting airway inflammatory responses.

OBJECTIVE To ensure the safety of patients’ drug use and control the risk of medical insurance expenditure by upgrading the pre-prescription review system to conduct pre-review on prescriptions from internet hospitals and external prescriptions， as well as to review the payment methods of drugs （including in-hospital and external drug dispensing）. METHODS The data interfaces of prescriptions from internet hospitals and external prescriptions were integrated to achieve real-time rational drug use intervention. Additionally， an intelligent review project for payment method was added to precisely intervene in the medical insurance payment methods of drugs. The effect of the system upgrade was evaluated by comparing the qualification rates of prescriptions from internet hospitals and external prescriptions and the suspected amounts of drug violations from January to April 2025 （before the system upgrade） and May to August 2025 （after the system upgrade）. RESULTS After the upgrade of the pre-prescription review system， the qualification rates of prescriptions from internet hospitals and external prescriptions increased by 3.5% [95% confidence interval （CI）＝0.3%-6.7%， P ＝0.037 ] ； the suspected amounts of drug violations decreased to 52.9% of the pre-upgrade level （95%CI＝31.6%-88.5%， P ＝0.026）， and the average monthly sequential decrease was 29.5% （95%CI＝12.2%-43.4%， P ＝0.012）. Moreover， the addition of the intelligent review project for payment methods promoted the management of off-label drug use in our hospital. After the upgrade， a total of 79 filling valid applications for off-label drug use were received and archived. CONCLUSIONS The upgrade of the pre-prescription review system effectively improves the review qualification rates of prescriptions from internet hospitals and external prescriptions and the accuracy of medical insurance payment for drugs， and strengthens the supervision of off-label drug use， achieving dual guarantees of clinical rationality and medical insurance compliance.

Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

Objectives:To explore the predictive value of residual Murray's law-based quantitative flow ratio(μQFR)on long-term vessel-oriented composite endpoints(VoCE).Methods:This retrospective study included 3 510 patients from the FAVOR Ⅲ China trial.Offline residual μQFR analysis was performed on all vessels(diameter≥2.5 mm)with 50%-90%stenotic lesions.Patients were stratified into high-,intermediate-,and low-risk groups based on residual μQFR tertiles.The primary endpoint was 3-year VoCE,defined as a composite of cardiac death related to the target vessel,target vessel-related spontaneous myocardial infarction,and ischemia-driven target vessel revascularization.Results:Offline analysis was performed on 5 256 vessels from 3 510 patients.The mean residual μQFR was 0.92±0.75.The high-risk group(residual μQFR≤0.91)with 1 554 patients(1 958 vessels);the intermediate-risk group(residual μQFR 0.92-0.96)with 1 211 patients(1 906 vessels);and the low-risk group(residual μQFR>0.96)with 745 patients(1 392 vessels).Over 3-year follow-up,VoCE occurred in 227 vessels(4.3%).The 3-year VoCE incidence was significantly higher in the high-risk group compared to the intermediate-and low-risk groups(6.2%vs.4.1%vs.2.5%,log-rank P<0.001),primarily driven by ischemia-driven target vessel revascularization(5.0%vs.3.0%vs.1.6%,log-rank P<0.001).Hypertension(OR=0.83,95%CI:0.72-0.96),hypercholesterolemia(OR=0.84,95%CI:0.73-0.97),bifurcation lesions(OR=0.72,95%CI:0.63-0.83),moderate/severe calcification(OR=0.70,95%CI:0.57-0.84),and tandem lesions(OR=0.59,95%CI:0.47-0.75)were independent predictors of lower residual μQFR values.Conclusions:Lower residual μQFR is significantly associated with increased VoCE risk during the 3-year follow up period.

Objective:To investigate the clinicopathological features and differential diagnosis of male genital system lympho-ma(MGSL).Methods:We retrospectively analyzed the clinicopathological and immunophenotypic features and prognosis of 80 ca-ses of MGSL.Results:The onset age of the MGSL patients ranged from 4 to 85(median 62)years old.All the cases showed non-specificity of the imaging features and clinical manifestations.MGSL was located mainly in the testis(n=66),followed by the pros-tate(n=7),epididymis(n=3),scrotum(n=3)and penile glans(n=1).Diffused large B cell lymphoma(DLBCL)was the most common pathological type(n=62),next came extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue(MALT)(n=7)and other rare types(n=12).During the 1-112-month follow-up of 10 of the 19 patients,1 died at 1 month af-ter diagnosed with prostatic B-lymphoblastic lymphoma(B-LBL)and another 1 died at 50 months after diagnosed with testicular DLBCL.Conclusion:MGSL is rare clinically,mainly of the DLBCL type pathologically,lacking specificity in clinical symptoms and imaging manifestation.The definite diagnosis of the malignancy depends on histopathology combined with related molecular exami-nation and immunohistochemical labeling,and R-CHOP chemotherapy is the first choice for its treatment.

Transcatheter aortic valve replacement(TAVR)has become an important therapeutic approach for severe aortic stenosis.However,complications associated with TAVR cannot be overlooked,among which contrast agents induced acute kidney injury(AKI)is a common complication.To explore methods to reduce the occurrence of AKI,this article reports two cases of successful treatment of severe aortic stenosis by TAVR under pure echocardiographic guidance,both of whom were elderly women aged 75 and 69,respectively,and both were implanted with a Evolute Pro 26 mm valve.Postoperative echocardiography showed good valve positioning and function.

Objective To analyze the prevalence and risk factors of underscreening among cervical cancer screening participants in Wuxiang County,Shanxi Province in 2019,providing evidence-based support for optimizing mobilization strategies.Methods Data from cervical cancer screening programs conducted between 2019 and 2024 in Wuxiang County were retrospectively collected.The follow-up screening behaviors of women screened in 2019 were analyzed,and factors associated with underscreening were identified.Results A total of 3759 women underwent cervical cancer screening in 2019.Among them,492 women(13.09％)with abnormal primary screening results requiring follow-up in 12 months,yet only 43(8.74％)completed;2154 women(57.30％)with negative liquid-based cytology testing(LCT)results needed re-screening after 3 years,701(32.54％)completed;1113 women(29.61％)with negative HPV/combined results needed re-screening after 5 years,734(65.95％)completed.Overall,2299 women(60.69％)exhibited underscreening.Multivariate analysis showed that underscreening was more likely among community residents than rural residents(OR=2.309,P=0.018),older women(OR=1.065,P＜0.001),those in organized screening compared to opportunistic screening(OR=3.789,P＜0.001),those undergoing LCT(OR=4.607,P＜0.001)or combined screening instead of human papillomavirus testing(OR=3.624,P＜0.001),and those with abnormal screening results(OR=6.859,P＜0.001).Conclusion Substantial proportions of cervical cancer screening participants demonstrate poor adherence to guideline-recommended screening intervals,and particularly need to focus on older women and those with abnormal screening results.Implementation of electronic screening record systems and emphasizing knowledge of periodical screening in health education could enhance compliance with"70％screening coverage"target for cervical cancer prevention.

Purpose To investigate the correlation between molecular typing of urothelial carcinoma(UC)and its clinicopathologic features and prognosis,in order to explore the prognostic markers and therapeutic targets for UC.Methods 115 patients with UC were retrospectively analyzed.Immunohistochemical markers GATA-3,CK20,CK5/6 and CD44 were used for molecular typing of UC(luminal-like type,basal-like type and null).Correlations between molecular typing and clinicopathological features were analyzed using the Chi-square test and Fisher precise test.Sur-vival analysis was performed using the Kaplan-Meier test and Log-rank test.Results The expression of GATA-3 and CK20 was negatively correlated with the clinical stage of UC,while the expression of CD44 was positively correlated with the clinical stage of UC(both P＜0.05).CK20 was a marker of good prognosis(P=0.03).The proportion of clinically advanced UC with basal-like type was significantly higher than that of luminal-like type(78.4％vs 53.4％,P=0.033).Among the histologic variants,UC with neuroendocrine differentiation(100％),sarcomatoid carcinoma(80.0％)and squamous differentiation(77.8％)were basal-like type.All plasmacytoid and lymphoepithelioma-like types,as well as 81.8％of micropapillary UC.Among the null phenotypes,the differential variant predominated(66.7％).Compared with the luminal-like type,although the prognosis of basal-like UC was worse,there was no sta-tistically significant difference(P＞0.05).Conclusion Patients with CK20-expressing UC had a significantly better prognosis.The main histologic variants types of basal-like type and coelomofacial type are different.Molecular typing of UC using immunohistochemical markers is suggestive of clinical staging and prognosis of patients.

Objective To investigate the value of amide proton transfer(APT)imaging in evaluating lymph-vascular space inva-sion(LVSI)of cervical cancer.Methods A retrospective analysis was conducted on the data of cervical cancer patients with patho-logically confirmed LVSI status.Based on the presence of LVSI,the patients were divided into LVSI positive group and LVSI nega-tive group.All patients underwent diffusion weighted imaging(DWI)and APT imaging before treatment,and the apparent diffusion coefficient(ADC)and APT values of the lesions were measured.An independent sample t-test was used to compare the differences in ADC and APT values between the two groups.The sensitivity,specificity and area under the curve(AUC)of ADC,APT and ADC+APT in predicting LVSI were observed by receiver operating characteristic(ROC)curve,and the diagnostic performance of the three was compared by DeLong test.Results A total of 78 patients were included,of which 54 were LVSI negative and 24 were LVSI positive.The ADC values in the LVSI positive group were significantly lower than those in the LVSI negative group(P＜0.001),while the APT values in the LVSI positive group were significantly higher than those in the LVSI negative group(P＜0.001).The sensitivities of ADC,APT and ADC+APT in predicting LVSI were 79.17％,83.33％ and 87.50％,respectively,the specificities were 75.93％,55.56％ and 77.78％,respectively,and the AUC were 0.828,0.759 and 0.868,respectively,indicating that the diag-nostic performance of ADC+APT was better than that of ADC and APT alone(P＜0.001).Conclusion APT imaging can preop-eratively predict the presence of LVSI status in cervical cancer.When combined with ADC,its diagnostic accuracy is higher than that of APT alone,providing a new approach for evaluating LVSI in cervical cancer.

Purpose To investigate the relationship between the expression of POSTN and NECTIN-3 in urothelial carcinoma(UC)and its clinicopathologic features and prognosis.Methods Clinical data of 115 UC patients were col-lected.EnVision two-step method was used for immunohistochemical analysis to determine the expression of POSTN and NECTIN-3 in UC and their correlation with clinicopathological features and prognosis.Transcriptomic data from TCGA database were used to analyze the correlation between the expression of POSTN and NECTIN-3 in bladder cancer and the pathological stage and prognosis of bladder cancer.qPCR and Western blot were used to detect the expression levels of POSTN and NECTIN-3 in tumor tissues and adjacent tissues of patients.Results TCGA database analysis showed that the expression level of NECTIN-3 in urinary bladder urothelial carcinoma(UBUC)was significantly lower than that in paracancer tissues,and POSTN expression was positively correlated with pathological stage.Prognostic a-nalysis showed that POSTN expression was negatively correlated with the overall survival of UBUC(P＞0.05),and NECTIN-3 expression was negatively correlated with disease-free survival of UBUC(P＞0.05).The experimental re-suits showed that patients with positive POSTN expression were more prone to perineural invasion[25 cases(86.2％)vs 4 cases(13.8％),P=0.019],vascular invasion[36 cases(83.7％)vs 7 cases(16.3％),P=0.007],and lymph node metastasis[24 cases(88.9％)vs 3 cases(11.1％),P=0.033].Additionally,the positive expression rate of POSTN in UBUC was significantly higher than that in upper tract urothelial carcinoma(UTUC)(75.0％vs 54.3％,P=0.028).Higher expression levels of POSTN and NECTIN-3 were associated with shorter overall survival,but the difference was not statistically significant(P＞0.05).Conclusion There is no significant correlation between NECTIN-3 and the clinicopathological features and prognosis of urothelial carcinoma,while the expression of POSTN is correlated with the invasive clinicopathological features of UC,which has certain suggestive significance for clinical stage and prognosis.
