OBJECTIVE To explore and predict the quality markers (Q-markers) of Compound xiebai capsules for the treatment of chronic obstructive pulmonary disease (COPD) by constituents analysis combined with network pharmacology and molecular docking studies, and to establish the quality standard of Compound xiebai capsules. METHODS UHPLC-TOF-MS was used for qualitative analysis of Compound xiebai capsules, and the candidate Q-markers of Compound xiebai capsules were screened by combining network pharmacology and molecular docking technology. Further, HPLC was applied to establish the fingerprints of 15 batches of Compound xiebai capsules and to conduct quantitative analysis of the main components. RESULTS A total of 51 components were identified from Compound xiebai capsules. Among them, 15 components, namely oxyberberine, methylworenine, coptisine, tetrahydroberberine, epiberberine, berberine, magnoflorine, gandensin, cucurbitacin D, hydroxygenkwan, jatrorrhizine, columbamine, quercetin, cucurbitacin R, and palmatine, were determined as the candidate Q-markers for Compound xiebai capsules in the treatment of COPD. A total of 13 common peaks were calibrated in the fingerprints of 15 batches of Compound xiebai capsules for COPD treatment, with similarity values ranging from 0.976 to 0.999 compared to the reference fingerprint. Seven components were identified among these peaks, namely peak 5 (magnoflorine), peak 8 (jatrorrhizine), peak 9 (epiberberine), peak 10 (columbamine), peak 11 (coptisine), peak 12 (palmatine), and peak 13 (berberine). Their respective contents were (0.267±0.048), (0.453±0.084), (0.572±0.160), (0.392±0.074), (1.076±0.273), (1.477±0.271), and (6.664±1.249) mg/g ( n =3). CONCLUSIONS This study predicted 15 candidate Q-markers of Compound xiebai capsules in the treatment of COPD and established the fingerprint along with a quantitative determination method for seven major components.

OBJECTIVE To evaluate the clinical value of dose-escalated postoperative radiotherapy(PORT)in improving local control and survival outcomes for head and neck adenoid cystic carcinoma(ACC)patients.METHODS This retrospective study analyzed 336 ACC patients treated with surgery plus PORT at Beijing Tongren Hospital from January 2015 to January 2021.Cohort stratification compared high-dose(>60 Gy,n=146)and conventional-dose(≤60 Gy,n=190)regimens.Survival analysis employed Kaplan-Meier estimates with log-rank testing,complemented by multivariate Cox regression for risk adjustment.RESULTS The cohort demonstrated 39.29%(132/336)cumulative local failure rate.The overall survival rates at 1,3,and 5 years after surgery were 98.81%,94.05%,and 90.48%,respectively.Dose-response relationships revealed:1.Significantly reduced local recurrence with high-dose PORT(28.08%vs.47.89%,P<0.001),corresponding to 41.37%lower recurrence risk(a HR=0.59,95%CI=0.38-0.91;P=0.041);2.Superior progression-free survival in the high-dose group(3-year:86.99%vs.76.32%;5-year:82.19%vs.66.32%,all P<0.05);3.Comparable overall survival between groups(median OS:200 vs.160 months,P=0.292).CONCLUSION Dose escalation beyond 60 Gy significantly enhances locoregional control and progression-free survival in head and neck ACC without conferring overall survival advantage,likely reflecting the disease's characteristic indolent metastatic progression.These results establish>60 Gy as an optimal dose threshold for PORT in high-risk ACC management.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma(ACB).Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males,with an average age of(61.3 ± 11.5)years. Twelve patients had comorbidities(6 hypertension,2 coronary heart disease,5 diabetes mellitus,and 3 cerebrovascular diseases)and 12 had a smoking history. The mean body mass index(BMI)was(24.8 ± 3.2)kg/m 2. The maximum tumor diameter measured by enhanced computed tomography(CT)was(29.7 ± 12.7)mm. The preoperative neutrophil-to-lymphocyte ratio(NLR)was 3.4 ± 3.2,and the systemic immune-inflammation index(SII)was(582 ± 496)× 10 9/L.Patients were divided into two groups according to the surgical approach:the radical cystectomy group( n = 23)and the bladder-sparing group( n = 10). For the radical cystectomy group,there were 19 males and 4 females,with a mean age of(59.9 ± 12.6)years. Five patients had comorbidities(3 hypertension,1 coronary heart disease,1 diabetes mellitus,and 2 cerebrovascular diseases). Eight patients had a smoking history,with a mean BMI of(25.2 ± 3.5)kg/m 2. The maximum tumor diameter was(33.6 ± 10.9)mm,the preoperative NLR was 3.5 ± 3.5,and the SII was(618 ± 558)× 10 9/L. For the bladder-sparing group,there were 9 males and 1 female,with a mean age of(64.5 ± 8.2)years. Seven patients had comorbidities(3 hypertension,1 coronary heart disease,4 diabetes mellitus,and 1 cerebrovascular diseases). Four patients had a smoking history,with a mean BMI of(23.5 ± 2.3)kg/m 2. The maximum tumor diameter was(20.7 ± 12.5)mm,the preoperative NLR was 3.1 ± 2.2,and the SII was(501 ± 323)× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities( P = 0.008)and maximum tumor diameter( P = 0.006),while no significant differences were found in other data( P > 0.05). The Kaplan-Meier survival curve was drawn,and Cox regression was used to analyze the prognostic factors of progression-free survival(PFS)and overall survival(OS)of patients. Results:Among the 33 patients,low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology,and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma,5 cases of lymph node metastasis,and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases(27.3%),8 cases(24.2%),7 cases(21.2%),and 9 cases(27.3%)respectively. Nine patients received postoperative adjuvant therapy,including 6 with adjuvant chemotherapy,2 with adjuvant chemotherapy combined with radiotherapy,and 1 with adjuvant immunotherapy. In the radical cystectomy group( n = 23),there were 13 cases of low-grade and 10 cases of high-grade pathological grading,2 cases with positive margins,19 cases of muscle-invasive bladder adenocarcinoma,5 cases of lymph node metastasis,1 case of distant metastasis,and 5 patients received adjuvant therapy(4 cases of adjuvant chemotherapy,and 1 case of adjuvant immunotherapy). In the bladder-sparing group( n = 10),there were 7 cases of low-grade,3 cases of high-grade pathological grading,1 case with positive margins,3 cases of muscle-invasive bladder adenocarcinoma,zero lymph node or distant metastasis,and 4 patients received adjuvant therapy(2 cases of adjuvant chemotherapy,and 2 cases of combined adjuvant chemotherapy and radiotherapy). A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups( P = 0.006),while no significant differences were observed in other data( P > 0.05).The median follow-up duration of the patients was 28.0 months,the median PFS was 86.0 months,and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS( P = 0.777)and OS( P = 0.585)between the radical cystectomy group and the bladder-preserving group. Female( P = 0.011),BMI < 25 kg/m2( P = 0.038),and positive surgical margins( P < 0.01)were associated with poorer PFS. Aged ≥ 70 years( P = 0.003),lymph node metastasis( P = 0.041),and positive surgical margins( P = 0.025)were associated with poorer OS,and patients in the adjuvant therapy group had better OS( P = 0.005). Multivariate Cox regression analysis indicated that positive surgical margins(HR 10.2, P = 0.012)were an independent impact factor for PFS,and positive surgical margins(HR 39.8, P = 0.001)and adjuvant therapy(HR 0.12, P = 0.021)were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.

Objective:To investigate the clinical and pathological characteristics, prognostic factors, and treatment outcomes of bladder adenocarcinoma.Methods:The data of 177 bladder adenocarcinoma patients treated at Renji Hospital, Shanghai Jiaotong University School of Medicine from January 2003 to December 2023, and 2 687 bladder adenocarcinoma patients from the SEER database (2000—2021) were reviewed retrospectively. The clinicopathological and prognostic characteristics were compared between the two cohorts. Patients with urachal adenocarcinoma or primary bladder adenocarcinoma were included, while metastatic bladder adenocarcinoma from other sites and urothelial carcinoma with glandular components were excluded. The Chi-square test was used for comparison of categorical data, and propensity score matching (1∶1) was applied to match baseline data between the Renji and SEER cohorts. Kaplan-Meier survival curves were generated, and log-rank tests were used for comparisons. Univariate and multivariate Cox regression analyses were performed using the survival R package, with P-values calculated via Wald tests. Results:The proportion of localized bladder adenocarcinoma was significantly higher in the Renji cohort than in the SEER cohort [61.0% (108/177) vs. 19.4% (521/2 687), P<0.001], and mucinous adenocarcinoma was more common in Renji cohort [33.3% (59/177) vs. 22.6% (607/2 687), P<0.001]. After matching for baseline factors, including SEER stage and pathological grade, survival analysis revealed that the Renji cohort patients had slightly better survival compared to the SEER cohort [median survival: 55.4 (24.1, 196.2) months vs. 39.2 (13.6, 137.4)months, P=0.033]. Multivariate Cox analysis identified SEER stage [Renji cohort: HR=3.83 (95% CI 1.62-9.07), P=0.002; SEER cohort: HR=3.67 (95% CI 3.13-4.31), P<0.001] and pathological grade [Renji cohort: HR = 2.76 (95% CI 1.54-4.95), P=0.001; SEER cohort: HR=1.46 (95% CI 1.29-1.65), P<0.001] as independent prognostic factors. In the Renji cohort, no significant differences were observed in the median progression-free survival [40.1 (19.5, 91.6) months vs. 40.9 (12.8, not reached)months, P=0.976] and overall survival [79.3 (37.1, 195.8) months vs. 53.9 (16.4, 129.5)months, P=0.374] between patients receiving adjuvant chemotherapy and those not receiving it. However, among patients with lymph node-positive bladder adenocarcinoma, adjuvant chemotherapy significantly improved both progression-free survival [40.1 (38.2, 75.4) months vs. 12.2 (3.1, 12.2)months, P=0.004] and overall survival [68.2 (46.2, 84.5)months vs. 28.1 (4.3, 28.3)months, P=0.006]. Conclusions:Bladder adenocarcinoma is rare and associated with poor prognosis. Compared to the SEER cohort, Renji cohort patients had more localized disease, with no significant differences in other features. SEER stage and pathological grade were independent prognostic factors in both cohorts. Lymph node-positive bladder adenocarcinoma patients in the Renji cohort benefited significantly from adjuvant chemotherapy.

[Objective] To explore the influencing factors of quality monitoring index on the nucleic acid pooling detection mode and continuously improve the detection quality of nucleic acid laboratory. [Methods] The quality monitoring indicators (NAT reactive rate, NAT resolution reactive rate, NAT invalid batch rate, NAT invalid result rate, equipment failure rate) and causes of invalidity in our laboratory from January 1, 2020 to December 31, 2022 were retrospectively analyzed. The quality monitoring indicators of the laboratory during 2020 to 2022 were compared longitudinally. The quality monitoring indicators of the laboratory in 2022 were compared horizontally with the overall level in Shandong for the same period to find the differences. [Results] From 2020 to 2022, a total of 218 686 samples were detected, the NAT reactive rate was 0.15‰ (32 samples in total), the resolution reactive rate was 39.02%, the invalid batch rate was 1.06%, the invalid result rate was 1.18%, and the equipment failure rate was 3.58%. There were no differences in the NAT reactive rate, NAT resolution reactive rate and NAT invalid batch rate among different years (P>0.05), but there were differences in the invalid result rate (P<0.05). Equipment failure was the main cause of invalid results (56.53%). Compared with other laboratories in Shandong, there were differences in the NAT reactive rate and invalid result rate (P<0.05). There were differences in the reaction rate, resolution rate and invalid result rate among different reagents (P<0.05). Compared with other two laboratories using the same manufacturer's reagent, there were differences in the reactive rate and invalid result rate (P<0.05), but no difference in the resolution rate and invalid batch rate (P>0.05). [Conclusion] Establishing quality indexes for process control and regular analysis can timely detect potential risks in laboratory operation. The use of quality indicators to implement self-comparison and inter-laboratory comparison can help the laboratory systematically and scientifically evaluate its own operating status and formulate corresponding quality management strategies, thereby improving the laboratory's testing capacity and ensure the safety of blood use.
