Objective:To investigate the effects of different types and administration times of defoaming agents on the gastric vision clarity before magnetically controlled capsule endoscopy (MCE) in children.Methods:A retrospective analysis was conducted on children who underwent MCE in Shanghai Children's Hospital, School of Medicine, Shanghai Jiao Tong University from January 2017 to March 2023.Children were divided into three groups based on type of defoaming agents: the simethicone emulsion group (10 mL simethicone emulsion), the dimethicone powder group (5 g dimethicone powder dissolved in 30 mL warm water), and the dimethicone emulsion group (4 mL dimethicone emulsion dissolved in 10 mL water). Each group was further divided into 3 subgroups based on the time of administration before the examination: 30 minutes, 45 minutes, and 60 minutes, resulting in a total of 9 subgroups. The primary outcome measure was the gastric bubble score. Secondary outcomes included gastric cleanliness score, examination time, gastric transit time (GTT), diagnostic efficacy, and safety assessment.Results:A total of 180 children (20 per group) were included in the study. The gastric bubble score (0.89 ± 0.35) and gastric cleanliness score (0.99 ± 0.52) in the 45-minutes subgroup of the dimethicone powder group were significantly lower than those in other groups, indicating better view clarity, with significant differences ( P<0.05). There were no significant differences in examination time, GTT, or the positive detection rate of gastric diseases among the groups ( P>0.05). Conclusion:Administration of defoaming agents before MCE can significantly reduce gastric bubbles and improve the view clarity of the gastric mucosa. The optimal regimen for children is taking 5 g dimethicone powder dissolved in 30 mL warm water 45 minutes before the examination.

Objective To investigate the diagnostic efficacy of targeted biopsy(TB)combined with ipsilateral hemiglandular systematic biopsy(SB)of the dominant lesion,so as to explore a novel reduced-core biopsy strategy.Methods A retrospective analysis was conducted on the clinical data of 299 patients treated in our hospital during Sep.1,2022,and Feb.28,2023,who had a Prostate Imaging Reporting and Data System(PI-RADS)score ≥3 and underwent combined TB and SB.The dominant lesion was defined as the lesion with the highest PI-RADS score on multi-parametric magnetic resonance imaging(mpMRI);in cases of identical scores,the largest was designated as the dominant.SB was categorized as ipsilateral(ipsi-SB)or contralateral(contra-SB)to the dominant lesion.The consistency in detecting clinically significant prostate cancer(csPCa)was compared between TB with ipsi-SB(TB+ipsi-SB),TB with contra-SB(TB+contra-SB),and TB with SB(TB+SB).Subgroup analyses were performed based on PI-RADS score,prostate-specific antigen(PSA)level,prostate volume(PV),and mpMRI lesion distribution to evaluate csPCa detection rates across different variables.Results TB+ipsi-SB demonstrated comparable detection rate to TB+SB(46.2％vs.46.8％).The K values for TB+ipsi-SB and TB+contra-SB relative to TB+SB were 0.987(95％CI:0.969-1.000,P＜0.01)and 0.933(95％CI:0.892-0.974,P＜0.01),respectively.Across all subgroups,TB+ipsi-SB showed the highest agreement with TB+SB.Notably,in subgroups with PI-RADS 3 and 5,PSA＞0-20 ng/mL,PV＜25 mL,bilateral or multiple mpMRI lesions,TB+ipsi-SB achieved complete concordance with TB+SB in csPCa detection[K=1.000(95％CI:1.000-1.000),P＜0.01].Conclusion For patients with PI-RADS score ≥3,TB+ipsi-SB exhibits near-perfect consistency with TB+SB in csPCa detection while requiring fewer biopsy cores.TB+ipsi-SB represents a promising refinement of the TB+SB approach.

Objective To conduct a rapid health technology assessment(rHTA)of the efficacy,safety,and cost-effectiveness of tirzepatide for the treatment of type 2 diabetes mellitus(T2DM),and to provide evidence for clinical medication.Methods PubMed,Web of Science,Embase,Cochrane Library,WanFang Data,CNKI databases,and health technology assessment(HTA)websites were searched to collect systematic reviews/Meta-analysis,pharmacoecomic literature and HTA reports of tirzepatide in the treatment of T2DM from inception to February 28,2025.Two researchers independently conducted literature screening,data extraction,and quality assessment,and then summarized and analyzed the results.Results A total of 13 articles were included,comprising 2 HTA reports,8 systematic reviews/Meta-analyses,and 3 pharmacoeconomic studies.In terms of efficacy,tirzepatide outperformed placebo or other antidiabetic drugs in reducing glycated hemoglobin(HbA1c),increasing the rate of HbA1c＜7％,lowering blood glucose,and reducing weight.The antihyperglycemic and weight-loss effects of tirzepatide were dose-dependent,and it also had certain advantages in reducing the risk of cardiovascular events and renal composite endpoint events.Regarding safety,the incidence of gastrointestinal adverse events in the tirzepatide group was higher than that in the placebo group and the insulin group,mainly manifested as diarrhea,nausea,and vomiting.However,it did not increase the risk of serious gastrointestinal adverse events,nor did it increase the risk of hypoglycemia and pancreatitis.In terms of cost-effectiveness,tirzepatide had cost-utility and cost-effectiveness advantages compared with semaglutide and other antidiabetic drugs.Conclusion Compared with other antidiabetic drugs,tirzepatide has better efficacy,safety,and cost-effectiveness in the treatment of T2DM.

The optimal regimen for children is taking 5 g dimethicone powder dissolved in 30 mL warm water 45 minutes before the examination.

Objective:To evaluate the diagnostic value of targeted biopsy of secondary lesion (SL) in systematic biopsy (SB) combined targeted biopsy for clinically significant prostate cancer (CsPCa).Methods:A retrospective analysis was conducted on the data of patients who underwent systematic biopsy combined target biopsy at Nanjing Drum Tower Hospital from January 2021 to February 2023, and they had at least two Prostate Imaging-Reporting and Data System (PI-RADS) score ≥3 lesions on prostate magnetic resonance imaging. The study included patients with a median age of 70 (65, 76) years old, median prostate specific antigen (PSA) was 9.1 (5.96, 13.62) ng/ml, median prostate volume was 39.1 (29.27, 53.25) ml, and median PSAD was 0.2 (0.15, 0.38) ng/ml 2.The index lesion (IL) was defined as the one with the highest PI-RADS score and SL was defined as the one with the second-highest PI-RADS score. If the two lesions had the same PI-RADS score, the one with larger maximum diameter was IL and the other one was SL. The median maximum diameter of IL and SL were 1.3 (1.06, 1.66) cm and 0.9 (0.69, 1.20) cm, respectively. The median maximum diameter ratio of IL and SL was 1.48 (1.10, 1.91), and the median maximum diameter difference of IL and SL was 0.9 (0.20, 1.89) cm. The IL in peripheral zone was found in 238 patients (62.63%) and SL in peripheral zone was found in 255 patients (67.10%). There were 204 patients (53.68%) having both IL and SL on the same side of prostate. According to the combination of PI-RADS scores of IL and SL, patients were categorized into various groups: 96 patients (25.26%) with IL3 and SL3, 79 (20.78%) with IL4 and SL3, 98 (25.78%) with IL4 and SL4, 21 (5.52%) with IL5 and SL3, 76 (20.0%) with IL5 and SL4, and 10 (2.63%) with IL5 and SL5. Targeted biopsy was performed on at least two of the most significant lesions. Comparison was performed in the detection rate of CsPCa between SB+ IL+ SL and SB+ IL (SL was omitted). To explore the factors influencing the detection rate of CsPCa, a multivariate logistic regression analysis was used. Results:The detection rate of CsPCa in this study was 78.95% (300/380) based on SB+ IL+ SL. After omitting SL target biopsy, the detection rate of CsPCa was 78.16% (297/380, P>0.05) under the condition of SB+ IL. No significant differences were noted between the two groups. The multivariate logistic regression analysis showed that PSA ( OR=1.11, 95% CI 1.05-1.20, P<0.01), prostate volume ( OR=0.98, 95% CI 0.96-0.99, P<0.01), SL maximum diameter ( OR=0.19, 95% CI 0.08-0.50, P<0.01), ratio of IL and SL maximum diameter ( OR=0.34, 95% CI 0.16-0.68, P<0.01), difference of IL and SL maximum diameter ( OR=1.50, 95% CI 1.10-2.29, P<0.05), and PI-RADS score group of IL and SL (IL3 vs. SL3 as the reference, IL4 vs. SL3 OR=4.79, 95% CI 2.21-10.91, P<0.01, IL4 vs. SL4 OR=23.11 95% CI 8.09-85.28, P<0.01, IL5 vs. SL3/4/5 OR=15.28 95% CI 5.21-48.55, P<0.01) were the influencing factors for detection rate of CsPCa. Conclusions:For patients with at least two PI-RADS score≥3 lesions on prostate magnetic resonance imaging, omitting SL can almost maintain the same detection efficacy.

Objective:To analyze the clinical features and immunotherapy responsiveness of patients with myelin oligodendrocyte glycoprotein immunoglobulin G-antibody associated disease (MOGAD) with epilepsy, and display the risk factors of epilepsy in MOGAD.Methods:Eighty-nine patients with MOGAD diagnosed at the First Affiliated Hospital of Zhengzhou University between October 2019 and May 2023 were enrolled and classified into 2 groups upon MOGAD with ( n=29) or without epilepsy ( n=60). The Expanded Disability Status Scale (EDSS) and Clinical Assessment Scale for Autoimmune Encephalitis (CASE) were used for evaluation of severity, and EDSS or CASE scores on the 30th day after first-line immunotherapy initiation lower than that on admission were defined as well treatment responsiveness. The differences of general data, clinical manifestations, cerebrospinal fluid (CSF) and peripheral blood biochemical examination results, and immunotherapy reactivity between the 2 groups were thoroughly explicated. In addition, the risk factors of epilepsy in MOGAD were analyzed by univariate and multivariate Logistic regression analysis. Results:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy were characterized by lower age of onset [24.5(10.3, 34.0) years vs 11.0(6.5, 20.0) years, Z=-2.348, P=0.019], higher percentage of male patients [43.3%(26/60) vs 75.9%(22/29), χ 2=8.326, P=0.004], higher virus infection rate [28.3%(17/60) vs 51.7%(15/29), χ 2=4.645, P=0.031], higher incidence of prodromal symptoms [11.7%(7/60) vs 34.5%(10/29), χ 2=6.586, P=0.010], higher blood-brain barrier breakdown rate [35.0%(21/60) vs 58.6%(17/29), χ 2=4.458, P=0.035], higher percentage of CSF albumin level>450 mg/L [48.3%(29/60) vs 75.9%(22/29), χ 2=6.056, P=0.014] and higher creatine kinase level [45.50(28.50, 69.75) U/L vs 57.50(41.75, 97.25) U/L, Z=-2.349, P=0.019]; more epilepsy [0(0) vs 29/29 (100.0%), χ 2=89.000, P<0.001] and disturbance of consciousness [0(0) vs 6/29(20.7%), χ 2=10.224, P=0.001] as clinical manifestations, and more cerebral cortex lesions [30/60(50.0%) vs 25/29(86.2%), χ 2=10.856, P=0.001] on magnetic resonance imaging. Nevertheless, the patients with MOGAD without epilepsy were featured with more visual impairment [23/60(38.3%) vs 3/29(10.3%), χ 2=7.406, P=0.007], limb weakness [18/60(30.0%) vs 1/29(3.4%), χ 2=8.209, P=0.004], sensory disturbance [15/60(25.0%) vs 0(0), Fisher exact probability test, P=0.002] and more cervical cord lesions [22/60(36.7%) vs 4/29(13.8%), χ 2=4.946, P=0.026] on magnetic resonance imaging. Immunotherapy responsiveness was relatively poor in the MOGAD with epilepsy group [EDSS score lower than that on admission: 15/29(51.7%) vs 46/60(76.7%), χ 2=5.641, P=0.018; CASE score lower than that on admission: 16/29(55.2%) vs 47/60(78.3%), χ 2=5.072, P=0.024] compared with the MOGAD without epilepsy group. Male was the independent risk factor of epilepsy in MOGAD ( OR=7.078, 95% CI 1.709-29.326, P=0.007). Conclusions:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy reported more male patients, lower age of onset and higher incidence of prodromal symptoms, blood-brain barrier dysfunction rate, virus infection rate, CSF albumin level and creatine kinase level; clinical phenotypes were mainly meningoencephalitis and more cerebral cortex lesions were shown on magnetic resonance imaging. MOGAD with epilepsy was closely related to poor immunotherapy responsiveness, and gender was found to be the independent risk factor for epilepsy in MOGAD.

Objective:To investigate the application value of a multi-dimensional digital moni-toring platform for perioperative period in gastric cancer patients.Methods:The retrospective cohort study was conducted. The clinical data of 50 patients who underwent laparoscopic radical gastrec-tomy in The Affiliated Hospital of Nanjing University of Chinese Medicine from July 2022 to January 2024 were collected. There were 35 males and 15 females, aged (64±12)years. All patients followed the concept of enhanced recovery after surgery, and the multi-dimensional digital monitoring platform based on wearable monitoring equipment was used to implement perioperative management measures. Observation indicators: (1) results of heart rate variability (HRV) monitoring; (2) results of blood glucose and blood oxygen monitoring; (3) results of exercise and sleep monitoring; (4) results of body composition monitoring. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(IQR). Repeated measurement data were analyzed using the repeated ANOVA. Measurement data with skewed distri-bution were transformed to normal distribution by SPSS transformation function before testing. For comparison between pre- and postoperation, paired sample t test was used for measurement data with normal distribution, and nonparametric Wilcoxon signed rank sum test was used for measure-ment data with skewed distribution. Results:(1) Results of HRV monitoring. From preoperation to the third day after surgery, the standard deviation normal to normal heart beat of 50 patients was changed from(103±26)ms to(101±36)ms, the mean of the standard deviations of normal to normal heart beat calculated per 5 min segment was changed from (45±16)ms to(33±12)ms, the number of pairs of adjacent NN intervals differing by more than 50 ms in the entire recording was changed from 6.02%(4.96%) to 5.79%(4.20%), the low frequency power was changed from 376.78(468.96)ms 2 to 742.79(525.20)ms 2, the high frequency power was changed from 273.61(273.58)ms 2 to 397.48(164.87)ms 2, the ratio of low frequency power to high frequency power was changed from 1.6±0.5 to 1.6±0.6, showing significant differences in above indicators before and after operation ( F=34.43, 26.15, 24.58, 5.51, 6.11, 6.02, P<0.05). (2) Results of blood glucose and blood oxygen monitoring. From preoperation to the third day after surgery, the blood glucose of 50 patients was changed from 6.75(2.05)mmol/L to 6.90(2.63)mmol/L, showng a significant difference before and after operation ( F=45.84, P<0.05). The blood oxygen was changed from 97.00%(5.00%) to 97.50%(3.00%), showing no significant difference before and after operation ( F=2.25, P>0.05). (3) Results of exercise and sleep monitoring. From preoperation to the third day after surgery, the number of steps fo 50 pati-ents was changed from 3 043(1 224) to 1 473(767), sleep duration was changed from(8.2±1.1)hours to(7.3±0.8)hours, sleep score was changed from 80±10 to 78±5,showing significant differences in above indicators before and after operation ( F=716.46, 29.02, 47.32, P<0.05).(4) Results of body composition monitoring. The body weight of 50 patients was changed from (63±8)kg to(61±8)kg before and after operation, body fat rate was changed from 24%±8% to 22%±9%, muscle mass was changed from 43 (12)kg to 41(17)kg, body mass index was changed from (23.0±2.6)kg/m 2 to(22.1±2.5)kg/m 2, showing significant differences in above indicators before and after operation ( t=8.19, 3.00, Z=-2.78, t=7.34, P<0.05), while there was no significant difference in basal metabolic indicators from (1 390±134)kcal to (1 379±139)kcal before and after operation ( t=1.02, P>0.05). Conclusion:The multi-dimensional digital monitoring platform for preoperative period can accurately monitor the perioperative stress level and evaluate the postoperative recovery of gastric cancer patients, which can present the visual results.

Objective:To investigate the efficacy and safety of modified Bikini approach periacetabular osteotomy in the treatment of developmental hip dysplasia under 50 years of age.Methods:The clinical data of 39 patients with developmental hip dysplasia who underwent periacetabular osteotomy in the Department of Orthopedics, Guizhou Provincial People′s Hospital from June 2016 to June 2021 were retrospectively analyzed.Among them, 20 patients (21 hips) underwent the improved Bikini approach (study group) and 19 patients (20 hips) underwent the improved Smith-Petersen approach (control group).In the study group, there were 3 males and 17 females, aged( M(IQR))27.5 (14.3) years (range:11 to 44 years).In the control group, there were 2 males and 17 females, aged 27.5 (19.3) years (range:17 to 47 years).Both groups were sutured in the same manner by the same physician.Incision length, operation time, intraoperative blood loss and complications were recorded.X-ray images, anterior central marginal angle (ACE), lateral central marginal Angle (LCE) and acetabulum tilt angle (Tonnis AI) were measured before and after the operation.The coverage rate of acetabulum to femoral head (AHI) was measured and calculated, and the healing time was observed.Harris Hip score, International Hip score (IHOT)-12 and visual analogue scale (VAS) were recorded before and after surgery.Vancouver Scar Scale (VSS) score and patient and observer scar assessment scale (POSAS) score were recorded 12 months after surgery.The independent sample t test,Wilcoxon rank sum test, χ2 test or Fisher exact test was used to compare the clinical efficacy between the two groups, respectively. Results:All patients successfully completed the operation.There was no significant difference in operation time and intraoperative blood loss between the two groups (all P>0.05).The incision length of the study group was smaller than that of the control group, and the difference was statistically significant (10.5(5.0)cm vs.15.0(3.0), W=309.000, P=0.007).Patients were followed up for (19.1±11.1) months (range:12 to 60 months).Femoral nerve stretching injury occurred in 2 cases and sciatic branch fracture occurred in 1 case in the study group, all of which recovered to normal at 3 months follow-up, while no corresponding injury occurred in the control group.Lateral femoral cutaneous nerve injury occurred in 3 cases in the study group and 2 cases in the control group.Delayed wound healing occurred in 1 case in each of the two groups, and both healed after re-operation debridement and suture.Pubic branch nonunion occurred in 4 patients in the study group and 5 patients in the control group.There were no serious complications such as sciatic nerve and femoral blood vessel injury between the 2 groups, and there was no statistical significance in the incidence of complications between the 2 groups (52.4%(11/21) vs.40.0%(8/20), χ2=0.631, P=0.427).The clinical healing time of the patient was (4.5±1.3) months after surgery (range:3.0 to 8.0 months).There were no significant differences in ACE, LCE, Tonnis AI and AHI between the 2 groups (all P>0.05).At the last follow-up, there were no significant differences in VAS,Harris hip score and IHOT-12 score between the two groups (all P>0.05).The incision scars in the study group were smaller than those in the control group, and the differences in VSS and POSAS were statistically significant (all P<0.05). Conclusion:Compared with the improved Smith-Petersen approach, the improved Bikini approach has the same early clinical efficacy in the treatment of patients with developmental hip dysplasia under the age of 50, and has the advantages of smaller postoperative incision scars, more hidden and beautiful incision, and no serious complications, which is worthy of further study and promotion.
