Objective:By using cognitive interviews,the interviewees' cognition and understanding of the inflammatory bowel disease(IBD) self-efficacy scale for adolescents and young adults (IBDSES-A) were evaluated,and the semantic content of IBDSES-A,which was initially translated into Chinese,was tested and revised.Methods:Using purposive sampling,15 IBD patients aged 12-18 were selected from Beijing Children's Hospital,Capital Medical University,between January and February 2025,stratified by age group and disease type.Two rounds of cognitive interviews were conducted.Feedback and suggestions from interviewees were analyzed using a question appraisal system for coding and integration.Based on expert panel discussions,ambiguous items were revised to finalize the Chinese version of the IBDSES-A.Results:In the first round,10 interviewees were interviewed,followed by 5 interviewees in the second round.There were no statistically significant differences ( P>0.05) between the interviewees of two rounds in terms of age,gender,and education level.During the first round of interview,interviewees expressed comprehension difficulties with 76.9% (10/13) of the items.Coding analysis revealed that the primary issue was "clarification",as unclear wording made it difficult for interviewees to fully grasp the intended meaning of certain items.Based on these findings,the expert panel revised 10 of the 13 items in the IBDSES-A.The second round of cognitive interview showed that the interviewees generally understood the revised items，achieving linguistic and semantic consistency with the original scale. Conclusion:The application of cognitive interviews in the translation process of the IBDSES-A helps reduce comprehension biases caused by inappropriate wording，ensuring that the localized version of the scale is more accessible and understandable to the target population.

Objective:To evaluate preoperative high-resolution thin-layer cervical enhanced CT used to predict the venous route of the submental flap reflux vein and its relationship with adjacent structures in order to guide the anatomical understanding and protection of submental flap in pharyngeal cancer surgery.Methods:Sixty consecutive patients with pharyngeal cancer who underwent submental flap repair surgery in our department from March 2022 to December 2024, as well as 60 patients who were accepted neck dissection suffering other cancers, were selected. Before surgery, high-resolution cervical enhanced CT scans were performed, and the position of the transverse section of the facial vein in the venous phase horizontal image gradually variation tendency was focused layer by layer. The direction and adjacent relationship of the submental flap reflux veins were determined and recorded. Combined with 60 patients with other head and neck tumors who underwent neck dissection in our department during the same period (a total of 120 cases, 240 sides), the classification and management of the draining veins of Fang′s mental flap were conducted. Type Ⅰ mainly drains into the internal jugular vein; Type Ⅱ mainly drains into the external jugular vein and Type Ⅲ mainly drains into the anterior jugular vein (often accompanied by an external jugular draining branch). The status and proportion of venous drainage were analyzed.Results:Vascular predictive coincidence rate was 98.3% (59/60) among the 60 patients with pharyngeal cancer. Only one patient was predicted to have a simple return to the external jugular vein. However, during the operation, in addition to the main return to the external jugular vein, a small portion also returned to the internal jugular vein. Submental flap reflux vessels were classified into three types based on intraoperative submental flap venous return in 60 cases of laryngopharyngeal cancer, in conjunction with the analysis of venous return patterns from 240 cervical CT scans. Type Ⅰ mainly refluxed to the internal jugular vein, accounting for 42.1%. Type Ⅱ mainly refluxed to the external jugular vein (47.9%). Type Ⅲ mainly refluxed to the anterior jugular vein (10.0%). The total detection rate of CT reading of 240 venous reflux was 98.7% (237/240). Vascular predictive coincidence rate was 97.9%(235/240).Conclusion:The detailed analysis of submental venous return vessels can accurately predict the direction of reflux veins and its surrounding areas by preoperative high-resolution enhanced CT scan. This provides reliable guidance for the anatomy and protection of the submental flap reflux veins during surgery.

Objective:To compare the survival outcomes of different subsequent treatment regimens in patients with locally advanced hypopharyngeal squamous cell carcinoma (HPSCC) who achieved partial response (PR) after neoadjuvant chemotherapy based on the gross tumor volume regression rate (GTVRR).Methods:This retrospective study included patients with locally advanced HPSCC treated at the Department of Head and Neck Surgery, Beijing Tongren Hospital, from January 2011 to December 2023. The cohort included 135 males and 3 females, aged from 35 to 77 years. All patients received 2-3 cycles of TPF regimen (paclitaxel+cisplatin+5-fluorouracil) neoadjuvant chemotherapy. Subsequent treatments included concurrent chemoradiotherapy or surgery combined with postoperative adjuvant radiotherapy. The impacts of different subsequent treatment modalities on the survivals and prognoses of patients were compared based on GTVRR thresholds of 50% and 70%. The χ 2 test was used to analyze influencing factors; survival analysis and intergroup comparisons were performed using the Kaplan-Meier method and Log-rank test; prognostic factors were assessed using univariate and multivariate Cox regression analyses. Results:The 5-year OS and PFS rates were 56.5% and 47.9%, respectively, while, the 10-year OS and PFS rates were 25.8% and 21.2%, respectively. The median OS was 75 months, and the median PFS was 48 months. The laryngeal function preservation rate for the entire cohort was 83.3%. The patients who underwent surgery combined with postoperative radiotherapy had significantly better OS and PFS outcomes than those treated with concurrent chemoradiotherapy ( P<0.05). Stratification based on GTVRR revealed that the surgery plus postoperative radiotherapy regimen was particularly effective for PR patients with a GTVRR of 30%-70%, showing significantly better OS and PFS compared to the concurrent chemoradiotherapy group ( P<0.05). Conclusion:The optimal subsequent treatment for PR-HPSCC may be surgery-based comprehensive treatment, particularly for patients with a GTVRR of 30%-70%. This study offers valuable insights for the stratified treatment of HPSCC, which could contribute to improving overall patient prognosis.

Objective To evaluate the efficacy and safety of enteric-coated metformin hydrochloride capsules(Junlida?)in patients with T2DM and poor glycemic control under lifestyle interventions.Methods In this study,419 patients with T2DM were recruited from 15 research centers from July 2020 to March 2022,and randomly divided into observation(Obs)group(n=209)and control group(Con,n=210)using a multicenter,randomized,double-blind,non-inferiority trial design.Patients in the Obs group were treated with enteric-coated Metformin hydrochloride capsules(Junlida?),and patients in the Con group were treated with Metformin hydrochloride tablets(Glucophage?).The optimal effective dose of 2 g/d was achieved within 4 weeks,and the reasonable dose was maintained until the end of treatment.The treatment period was 24 weeks.HbA1c and its compliance rate,FPG,and body weight were compared between the two groups in full analysis set(FAS)and protocol set(PPS).Safety and adverse events(AE)were evaluated in safety set(SS).Results A total of 414 participants were randomized(207 cases in Obs group and 207 cases in Con group).414 cases in FAS population(207 cases in Obs group and 207 cases in Con group),and 328 cases in PPS population(164 cases in Obs group and 164 cases in Con group),and 414 cases in SS population(207 cases in Obs group and 207 cases in Con group).After treatment,HbA1c,FPG and body weight were lower in both groups(P<0.05)in FAS and PPS.HbA1c compliance rate was not significantly different between the two groups in FAS and PPS(P>0.05).The results of non-inferiority test showed that the lower limit was>-0.4%in both FAS(-0.154,95%CI-0.384～0.069)and PPS(-0.139,95%CI-0.390～0.112),and the Obs group reached non-inferiority end point.The achievement rate,compliance rate,safety index and incidence of AE were not significantly different between the two groups(P>0.05).Conclusions Junlida? demonstrated non-inferiority to Glucophage? in glycemic control and can be safely and effectively used in patients with diabetes.

Blood from a case of group B epidemic cerebrospinal meningitis identified in February 2024 in Ganzhou City,Jiangxi Province,and throat swabs from close contacts were collected for isolation and culture.The isolates were subjected to serogrouping,drug sensitivity testing,and whole genome sequencing and analysis,to provide a basis for epidemiological inves-tigation and clinical drug use.One strain of Neisseria meningitidis was isolated from the blood of the case and denoted group B.The MLST type was ST-7962,with no clonal group attribution.The phylogenetic tree showed that it was genetically close to the 1977 Shanghai carrier isolate(id-52231).Drug sensitivity results indicated that the strain was sensitive to 8 drugs:azithro-mycin,cefotaxime,minocycline,ceftriaxone,chloramphenicol,meropenem,rifampicin,and benzylpenicillin;resistant to cot-rimoxazole,levofloxacin,and ciprofloxacin;and showed an intermediate response to penicillin.This report describes the first case of ST-7962 group B meningoencephalitis found in Jiangxi Province.Monitoring of Neisseria meningitidis carriage,drug re-sistance,and molecular characteristics of strains in the healthy population in this region should be strengthened,to provide la-boratory support for the clinical use of medications,traceability,and control of the pathogen underlying meningoencephalitis infection.

Objective:To explore the correlation between the post-traumatic stress disorder(PTSD)level and postoperative fear disease progression and quality of life in patients undergoing laparoscopic myomectomy,and to analyze the related factors affecting the occurrence of PTSD in patients.Methods:120 patients who underwent laparoscopic myomectomy in Ruijin People's Hospital from April 2022 to April 2024 were selected,the PTSD occurrence was assessed with the Civilian version of PTSD checklist-civilian version(PCL-C)1 month after operation,and the progression of fear of Disease was assessed with the fear of progression questionnaire-short form(FoP-Q-SF),the quality of life was assessed with uterine fibroid symptoms and health-related quality of life questionnaire(UFS-QOL).The correlation between PTSD level and postoperative fear disease progression and quality of life in patients undergoing laparoscopic myomectomy was analyzed,and the factors of PTSD in patients undergoing laparoscopic myomectomy were analyzed by multivariate Logistic regression.Results:PTSD scores of in patients undergoing laparoscopic myomectomy was(36.93±5.69)score,fear of disease progression was(26.00±1.66)score,quality of life was(54.27±4.82)score.The total score of PCL-C was positively correlated with the total score of FoP-Q-SF,and negatively correlated with the total score of UFS-QOL(P＜0.05).The patients were divided into PTSD group(n=30)and non-PTSD group(n=90)according to whether or not occurrence of PTSD at 1 month after operation.Univariate analysis showed that,there were significant differences in age,education level,family income,number of fibroids,operation time and preoperative anxiety level between the PTSD group and the non-PTSD group(P＜0.05).Multivariate Logistic regression analysis showed that age ≥35 years old,operation time ≥90 min,preoperative anxiety level of moderate to severe,and increased total score of FoP-Q-SF were independent risk factors for PTSD in patients undergoing laparoscopic myomectomy(P＜0.05),and increased total score of UFS-QOL were protective factors(P＜0.05).Conclusion:The PTSD level in patients undergoing laparoscopic myomectomy is positively correlated with fear disease progression and negatively correlated with quality of life.Age,operation time,preoperative anxiety,fear disease progression and quality of life were the factors that influenced the occurrence of PTSD.

AIM:This study aims to investigate the impact of chronic kidney disease(CKD)on the growth,development,and cognitive function of offspring rats,and to evaluate the effects of esaxerenone(ESAX)intervention.METHODS:Thirty female non-pregnant Wistar rats were randomly assigned to three groups:sham operation+pregnancy(control group),UUO+pregnancy(model group),and UUO+pregnancy+esaxerenone(treatment group),with 10 rats in each group.CKD was induced in the UUO+pregnancy and UUO+pregnancy+esaxerenone groups by performing uni-lateral ureteral obstruction(UUO),while the sham operation+pregnancy group underwent a non-ligated and non-clipped ureter procedure.Rats in the treatment group received esaxerenone at a dosage of 1 mg·kg-1·d-1.Vaginal smears were per-formed weekly from the 8th week post-UUO to monitor the estrous cycle.Female and male rats in pre-estrus or estrus were paired in a 2∶1 ratio,and the day with the first appearance of sperm in vaginal smears was recorded as the first day of preg-nancy.Offspring were delivered 21 to 22 days post-gestation,and 10 offspring from each group were selected for further experimentation:sham-offspring(sham-offspr)group,UUO-offspro group,and esaxerenone treatment offspring(ESAX-offspr)group.At 21 days of age,offspring weight and tail length were measured.Behavioral tests,including the open field test,Y maze test,and Morris water maze test,assessed learning and memory abilities.Serum levels of aldosterone,5-hydroxytryptamine(5-HT),and brain-derived neurotrophic factor(BDNF)were measured using ELISA.Serum creati-nine(SCr)and blood urea nitrogen(BUN)levels were assessed using conventional biochemical methods.Renal pathology was examined using Hematoxylin-Eosin(HE)staining.RESULTS:Offspring in the UUO-offspr group had reduced body weight and tail length compared to the sham-offspr group(P＜0.05).Behavioral tests indicated that exploration and memo-ry abilities were significantly impaired in the UUO-offspr group compared to the sham-offspr group(P＜0.05),while the ESAX-offspr group showed improved behavioral development compared to the UUO-offspr group(P＜0.05).ELISA results revealed decreased levels of serum 5-HT,BDNF,and aldosterone in the UUO-offspr group compared to the sham-offspr group(P＜0.01),with increased levels in the ESAX-offspr group(P＜0.05).Renal function tests showed elevated SCr and BUN levels in the UUO-offspr group compared to the sham-offspr group(P＜0.01),while levels in the ESAX-offspr group were reduced(P＜0.01).HE staining demonstrated mild tubular dilation and inflammatory cell infiltration in the UUO-offspr group,whereas the ESAX-offspr group had well-arranged tubules with reduced inflammation.CONCLU-SION:Chronic kidney disease adversely affects the growth,development,and cognitive function of offspring rats by 21 days of age.Esaxerenone intervention can mitigate these detrimental effects on growth,development,and cognitive abili-ties in offspring rats.

AIM:To explore the role and mechanism of calcium-sensing receptor(CaSR)in regulating macro-phage polarization in hypertensive rats.METHODS:Male spontaneously hypertensive rats(SHR)and Wistar-Kyoto(WKY)rats were categorized into WKY group,SHR group,SHR+R568(CaSR agonist)group,and SHR+NPS2143(CaSR inhibitor)group.The thoracic aorta was isolated,and the expression of CaSR and macrophage polarization markers in the aorta was observed through immunofluorescence staining.The primary peritoneal macrophages of SHR and WKY rats were aseptically extracted following anesthesia.After intervention with R568 and NPS2143,the expression levels of M1 and M2 markers of peritoneal macrophages were observed by Western blot and immunofluorescence staining.The levels of interleukin(IL)-1β and IL-10 were measured by ELISA.The concentration of Ca2+in peritoneal macrophages was mea-sured by immunofluorescence.Western blot was employed to identify the expression of CaSR and nucleotide-binding oligo-merization domain-like receptor protein 3(NLRP3)inflammasome components.Following anesthesia,vascular smooth muscle cells(VSMCs)were isolated from SHR using an adherent method.Subsequently,a co-culture system was estab-lished with macrophage supernatant.The optimal action time for this co-culture system was determined through CCK-8 as-say.RESULTS:Compared with SHR group,activation of CaSR resulted in a significant decrease in the protein expres-sion of M1 polarization markers(P<0.05)and a concomitant increase in the protein expression of M2 polarization markers in the aorta(P<0.05).Compared with SHR group,administration of R568 led to a significant decrease in the protein ex-pression of M1 polarization markers(P<0.05)and a concomitant increase in the protein expression of M2 polarization markers(P<0.05)in peritoneal macrophages.Additionally,there was a notable reduction in the protein levels of NLRP3 inflammasome components(P<0.05).Furthermore,the fluorescence intensity of intracellular Ca2+was significantly en-hanced following R568 treatment(P<0.05).After administration of MCC950,an NLRP3 inflammasome inhibitor,the re-sults were consistent with those observed following R568 treatment,demonstrating statistical significance(P<0.05).This effect was reversed by the combined intervention of U73122,a phospholipase C(PLC)inhibitor(P<0.05).Compared with the control(0 h),the 24-h peritoneal macrophage supernatant exhibited the strongest capacity to enhance the viabili-ty of VSMCs after 24 h of culture(P<0.05).CONCLUSION:In hypertensive rats,the CaSR inhibits NLRP3 inflamma-some activation via the PLC-Ca2+signaling pathway,thereby mediating an increase in macrophage polarization towards the M2 phenotype and a decrease towards the M1 phenotype.
