Objective:To evaluate the application value of interactive learning in enhancing the diagnosis of breast cancer by residents in the department of radiology through training based on the interpretation of breast magnetic resonance imaging (MRI) features by the breast imaging reporting and data system (BI-RADS).Methods:A total of 23 trainees completed BI-RADS standardized reports of 250 cases. These cases were divided into a pre-training group (Group 1) and post-training groups (initial training, Groups 2-4; advanced training, Groups 5-6), forming a total of six groups. The efficacy of interactive learning through course lectures and case-based practice in enhancing their ability in breast cancer diagnosis was analyzed. All trainees generated reports based on the BI-RADS scoring criteria. Interpretation agreement rates, evaluation time, and confidence levels were recorded. SPSS 25.0 was used for independent samples t test, chi-square test, and rank-sum test. Results:During the initial stage of training, the agreement rate of 150 cases reached 80.00%, which was recommended as the endpoint for completion of the initial learning phase. A significant difference existed between Group 4 and Group 1 ( P=0.012) in agreement rate. Statistically significant differences were noted in evaluation time for Groups 5 and 6 before and after advanced training ( P=0.001 and 0.007, respectively). A significant difference in confidence level was observed for Group 5 ( P=0.005). Conclusions:Interactive training based on BI-RADS standardized reporting can improve the diagnosis of breast diseases by residents in the department of radiology, particularly for enhancing the quality of reports for mass-like enhancement breast diseases.

Objective: Surgical procedures for patients with posttraumatic syringomyelia (PTS) remain controversial. Until now, there have been no effective quantitative evaluation methods to assist in selecting appropriate surgical plans before surgery. Methods: We consecutively enrolled PTS patients (arachnoid lysis group, n = 42; shunting group, n = 14) from 2003 to 2023. Additionally, 19 intrathecal anesthesia patients were included in the control group. All patients with PTS underwent physical and neurological examinations and spinal magnetic resonance imaging preoperatively, 3–12 months postoperatively and during the last follow-up. Preoperative lumbar puncture was performed and blood-spinal cord barrier disruption was detected by quotient of albumin (Qalb, cerebrospinal fluid/serum). Results: The ages (p = 0.324) and sex (p = 0.065) of the PTS and control groups did not differ significantly. There were also no significant differences in age (p = 0.216), routine blood data and prognosis (p = 0.399) between the arachnoid lysis and shunting groups. But the QAlb level of PTS patients was significantly higher than that of the control group (p < 0.001), and the shunting group had a significantly higher QAlb (p < 0.001) than the arachnoid lysis group. A high preoperative QAlb (odds ratio, 1.091; 95% confidence interval, 1.004–1.187; p = 0.041) was identified as the predictive factor for the shunting procedure, with the receiver operating characteristic curve showing 100% specificity and 80.95% sensitivity for patients with a QAlb > 12.67. Conclusion Preoperative QAlb is a significant predictive factor for the types of surgery. For PTS patients with a QAlb > 12.67, shunting represents the final recourse, necessitating the exploration and development of novel treatments for these patients.

Objective:To explore the feasibility of pressure tolerance threshold (PTO) in evaluating the effect of local anesthesia in patients undergoing transperineal prostate biopsy.Methods:Patients who underwent periprostatic nerve block prostate biopsy in Northern Jiangsu People's Hospital from March 2022 to October 2023 were prospectively enrolled.Inclusion criteria: ① suspicious prostate nodules detected by digital rectal examination, any prostate-specific antigen (PSA) value; ② transrectal prostate ultrasound (TRUS) or magnetic resonance imaging (MRI) showing suspicious lesions, any PSA; ③ the PSA >10 ng/ml; ④PSA 4-10 ng/ml, suspicious free/total PSA or suspicious PSA density. Inclusion was required if one of these criteria was met. Exclusion criteria: ① previous history of prostate biopsy or prostate surgery; ② severe cardiovascular and cerebrovascular diseases or coagulation disorders; ③ severe urinary tract infection; ④ taking analgesics within 24 hours before surgery; ⑤ unable to complete the pain score or refused to cooperate; ⑥ rectal stenosis or other rectal lesions detected by digital rectal examination.The PTO of all patients was measured by the same physician using a tenderness measuring instrument before puncture. Visual analogue scale (VAS) was used to evaluate the pain during the operation. According to the VAS score, the patients were divided into mild pain group (VAS score 0-3 points) and moderate to severe pain group (VAS score 4-10 points). The clinical data of the two groups were compared. The correlation between PTO and VAS score was further analyzed. The receiver operating characteristic (ROC) curve of PTO to predict pain during puncture was drawn, and the optimal cut-off value of PTO was calculated by the maximum Youden index.Results:A total of 304 patients were enrolled in this study, including 184 patients in the mild pain group and 120 patients in the moderate to severe pain group.There were no significant differences in age [69 (63, 73) years old vs. 69 (61, 74) years old], body mass index[24.0(22.9, 25.0)kg/m 2 vs. 23.9(22.8, 24.7)kg/m 2], PSA[14.6(10.5, 25.1)ng/ml vs. 14.0(10.5, 20.7)ng/ml], and hypertension[59.8%(110/184) vs.64.2%(77/120)]between the mild pain group and the moderate to severe pain group ( P> 0.05), while there were significant differences in PTO[(6.69±1.20)kgf/cm 2 vs.(5.13±0.92)kgf/cm 2], number of puncture needles[19(18, 22)needles vs. 22(20, 24)needles], prostate volume[36.5(26.6, 52.5)ml vs. 63.2(47.4, 89.4)ml], diabetes[35.3%(65/184) vs. 23.3%(28/120)], and major trauma experience[37.5%(69/184) vs.15.8%(19/120)] ( P<0.05). There was a high correlation between PTO and VAS score ( r=0.689, P<0.001). ROC curve analysis showed that when PTO was 5.99 kgf/cm 2, the accuracy of predicting moderate to severe pain during prostate biopsy was the highest. The AUC was 0.848, the Youden index was 0.675, the sensitivity and specificity were 89.2% and 78.3%, respectively. Conclusions:PTO can evaluate the effect of local anesthesia in patients undergoing transperineal prostate biopsy.PTO can be measured before surgery in patients undergoing transperineal prostate biopsy. When the patient's PTO is ≥5.99 kgf/cm 2, the patient's pain tolerance is better and the local anesthesia effect is feasible.When the patient's PTO is less than 5.99 kgf/cm 2, the patient's pain tolerance is poor, so the patient could be recommended to undergo spinal anesthesia or general anesthesia to reduce the pain during prostate biopsy.

Objective To analyze the effects of vesicoprostatic muscle(VPM)reconstruction on the early urinary control recovery and safety of patients undergoing robot-assisted radical prostatectomy(RARP).Methods A total of 128 patients who underwent RARP in our hospital during Sep.1,2021 and Aug.31,2023 were enrolled and divided into the non-reconstruction group(n=64)and reconstruction group(n=64)using random number table method.The reconstruction group received Montsouris+VPM reconstruction surgery,while the non-reconstructive group underwent Montsouris surgery only.Urinary control and perioperative data were collected with telephone interview,outpatient follow-up and inpatient records.The two groups were matched using overlap weighting and the Kaplan-Meier method was used to calculate urinary incontinence rates at 1,2 and 3 months after extubation.Early urinary control(3 months after extubation),operation time,intraoperative bleeding,positive rate of incision margin,and incidence of early postoperative complications(＜30 days)(Clavien-Dindo scale)were compared between the two groups.Results The recovery rate of urinary control at 1,2 and 3 months after extubation was significantly higher in the reconstruction group than that in the non-reconstruction group(33.9％vs.11.2％;46.7％vs.16.1％;70.6％vs.45.6％,P＜0.05),but the positive rate of resection margin was lower(16.1％vs.41.7％,P＜0.05).There were no significant differences in operation time,intraoperative bleeding and early postoperative complications between the two groups(P＞0.05).Conclusion VPM reconstruction can improve urinary control recovery in RARP patients early after extubation without increasing the risk of surgery.

Objective:To explore the clinical and genetic characteristics of a child with autosomal recessive primary microcephaly (MCPH).Methods:A case study has been carried out on a boy who had presented at the Inner Mongolia Maternity and Child Health Care Hospital for microcephaly and mental deficiency in September 2022. Prenatal ultrasound images were retrospectively analyzed, and whole exome sequencing and Sanger sequencing were carried out for his family. A literature review was also carried out using keywords such as " ASPM gene", "microcephaly", "prenatal diagnosis", "primary microcephaly", " ASPM", "MCPH5", "MCPH", "autosomal recessive microcephaly", and "prenatal diagnosis on ultrasonography" on the PubMed database, Wanfang Data and China National Knowledge until September 2023. This study was approved by Medical Ethics Committee of the Inner Mongolia Maternity and Child Health Care Hospital (Ethics No. 2021-093-1). Results:The proband had shown progressive reduction in biparietal diameter (BPD) and head circumference (HC) during the fetal period. He was found to harbor compound heterozygous variants of the ASPM gene, which included a paternally derived c. 8044C>T (p.R2682X) and a maternally derived c.8652dup (p.A2885Sfs*35). Both variants were classified as pathogenic (PVS1+ PM2_Supporting+ PP4; PVS1+ PM2_Supporting+ PM3) based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). For other fetuses in his family, prenatal ultrasound and genetic testing were all normal. Literature research has identified 11 relevant articles, which included 14 MCPH cases. All of the MCPH5 cases had shown various degrees of reduced BPD/HC on fetal imaging (100%, 15/15). Developmental delay, intellectual disability, and attention deficits were noted in all survived cases, with one case having seizures (12.5%, 1/8). Their genotypes had included homozygotes (46.2%, 6/13) and compound heterozygotes (53.8%, 7/13) for nonsense variants (45%, 9/20) and frameshifting variants (55%, 11/20). Conclusion:The compound heterozygous variants c. 8044C>T (p.R2682X) and c. 8652dup (p.A2885Sfs*35) of the ASPM gene probably underlay the reduced BPD and HC in this proband with MCPH.

Objective:To explore the relieving effect of adhesive Bifidobacterium on constipation and its effect on intestinal flo-ra and intestinal morphology in mice.Methods:Detection of adhesion of 14 strains of Bifidobacterium.Fifty mice were randomly divid-ed into control group,model group,positive drug group,low adhesion group and high adhesion group,with 10 mice in each group.The control group and model group received 0.2 ml sterile double distilled water,the positive drug group received 0.2 ml 1.52 mg/kg lactulose solution,and the low and high adhesion groups received 0.2 ml 109 CFU/ml corresponding to Bifidobacterium solution for 37 days.The constipation model was established from the 31st day.The other 4 groups except the control group were given 0.2 ml 10 mg/(kg·bw)loperamide hydrochloride aseptic aqueous solution for 7 days.After the establishment of the model,each mouse was fed with 0.2 ml activated carbon suspension,and the excretion time of the first black stool was measured.After fasting for 12 hours,the mice were given aseptic double steamed water or loperamide hydrochloride,and 1 hour later,0.2 ml activated carbon suspension was given to the stomach.After 30 min,all the mice were killed.The distance between the intestinal length and the intestinal propul-sion of the activated carbon suspension was measured,and the intestinal propulsion rate was calculated.The fresh feces of mice on the 30th and 36th day were collected within 4 hours,and the fecal moisture content and short chain fatty acid(SCFAs)content were deter-mined.Observation of histology of small intestine by HE staining.The expression of zonula occluden-1(ZO-1)and Occludin was detected by immunofluorescence.Detection of aquaporin,c-kit and serotonin related gene transcription by qRT-PCR.The levels of 5-hydroxytryptamine(5-HT),IL-1β and TNF-α were detected by ELISA.The relative content of intestinal microflora was detected by 16S rRNA high-throughput sequencing.Results:CCFM 622,CCFM 624,CCFM 626,CCFM 641 and CCFM 642 were selected as the bacteria group used in the low adhesion group,and CCFM 16,CCFM 625,CCFM 643,CCFM 666 and CCFM 668 as the bacteria group used in the high adhesion group.Compared with control group,the first black stool excretion time,AQP4,AQP8 mRNA,5-HT,IL-1β and TNF-α levels in the model group,positive drug group,low adhesion group and high adhesion group increased(P<0.05),while the intestinal propulsion rate,fecal water content,ZO-1,Occludin fluorescence intensity,c-kit,5-HT4R,Tph1 mRNA,acetic acid,propionic acid and butyric acid decreased(P<0.05).Compared with positive drug group and high adhesion group,the first black stool excretion time,AQP4,AQP8 mRNA,5-HT,IL-1β and TNF-α in low adhesion group increased(P<0.05),while intestinal pro-pulsion rate,fecal water content,ZO-1,Occludin fluorescence intensity,c-kit,5-HT4R,Tph1 mRNA,acetic acid,propionic acid and butyric acid decreased in low adhesion group(P<0.05).In the control group,the mucosal structure was intact,the small intesti-nal villi were neat and uniform,there was no injury or wrinkle,and the cell structure was intact;in model group,the intestinal villi were seriously ruptured and atrophied,and the goblet cells were incomplete;compared with model group,the morphology of small intestinal villi in positive drug group,low adhesion group and high adhesion group were improved,and the number of goblet cells increased,and the improvement in positive drug group and high adhesion group were more obvious than that in low adhesion group.Compared with control group,the Shannon index and Firmicutes/Bacteroidetes(F to B)ratio in model group decreased(P<0.05),and there were differences in genus level(P<0.05).Compared with model group,Shannon index and F to B ratio increased in positive drug group,low adhesion group and high adhesion group(P<0.05).The sample points in the model group could be distinguished from the control group,positive drug group,low adhesion group and high adhesion group,but the coincidence degree of sample points in control group,positive drug group,low adhesion group and high adhesion group were higher.Conclusion:Bifidobacterium can regu-late intestinal flora of constipation mice,improve intestinal running efficiency and protect intestinal mucus barrier.Bifidobacterium with high adhesion is better than Bifidobacterium with low adhesion in relieving constipation in mice.
