OBJECTIVE: To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. METHODS: A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups ( P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. RESULTS: Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant ( P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group ( P<0.05), the incision was significantly longer ( P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups ( P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups ( P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups ( P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups ( P<0.05). There was no significant difference between the two plate groups ( P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups ( P>0.05). CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.

Objective:To construct a deep learning model based on YOLOV8-Seg algorithm to conduct automatic segmentation for the central gland(CG)and peripheral zone(PZ)of prostate,so as to provide a reliable basis for clinical diagnosis and treatment.Methods:The sequence data of T2-weighted imaging(T2WI)of horizontal relaxation time of 158 patients were selected from a public data set of magnetic resonance imaging(MRI)for prostate MRI,which was provided by the Charité University Hospital in Berlin,were selected.The all data were divided into a training set(109 cases),a validation set(16 cases),and a test set(33 cases)as the ratio of 7 to1 to 2.A lightweight asymmetric decoupled head(LADH)structure and the large kernel UniRepLKNetBlock module were integrated into the YOLOV8-Seg algorithm to enhance the capabilities of model's extraction feature,and the new model was named as YOLOV8-URLK.The assessment model with mean Average Precision(mAP),Dice Similarity Coefficient(DSC),95%Hausdorff Distance(HD95),and Average Surface Distance(ASD)was adopted to segment performance of the detection at prostate CG and PZ.Comparative experiments were conducted among that and YOLOV8-Seg,TransU-Net,and U-Net network,so as to validate the effectiveness of YOLOV8-URLK for detection and segmentation at prostate zone.Results:On the test set,the mAP@0.5(box)of YOLOV8-URLK model was 0.878,and the mean Dice coefficients,the mean HD95 values and the ASD values of that at CG and PZ were respectively(0.867,17.123 and 1.461)and(14.902,0.898 and 1.112).On the test set,the mAP@0.5(box)of YOLOV8-Seg model was 0.860,and the mean Dice coefficients of that at CG and PZ were 0.851 and 0.884,the mean HD95 values of that at them were 19.174 and 15.298,and ASD values of that at them were 1.781 and 1.219,respectively.On test set,the mean Dice coefficients of TransU-Net model at CG and PZ were 0.864 and 0.824,and the mean HD95 values of that at them were 18.134 and 19.402,and ASD values of that at them were 1.698 and 1.717,respectively.On the test set,the mean Dice coefficients of the U-Net model at CG and PZ were 0.857 and 0.690,and the mean HD95 values of that at them were 18.976 and 26.934,and ASD values of that at them were 1.753 and 2.135.The YOLOV8-URLK model can better reappear the segmentation trend of manual annotations.Conclusion:The YOLOV8-URLK model demonstrates higher precision in the detection and segmentation of MRI images of prostate,which were superior to YOLOV8-Seg,TransU-Net and U-Net.It can enhance the efficiency of the detection and segmentation.

OBJECTIVE To explore the risk factors for peritoneal dialysis-associated peritonitis(PDAP)in the type 2 diabetes mellitus patients complicated with renal anemia and construct the risk prediction model so as to provide references for clinical diagnosis and treatment of PDAP.METHODS A total of 142 type 2 diabetes mellitus patients who were complicated with renal anemia and underwent peritoneal dialysis in nephrology department of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine from Jan.2017 to Dec.2023 were recrui-ted as the research subjects and were divided into the peritonitis group with 68 cases and the non-peritonitis group with 74 cases according to the status of complication with PDAP.The related data were collected,the univariate a-nalysis and binary logistic regression analysis were performed,the risk prediction model was established,and the obtained model was visualized for further analysis.RESULTS The univariate analysis showed that the age and lev-els of glycosylated hemoglobin,triglyceride and fibrinogen were higher in the peritonitis group than in the non-per-itonitis group;the levels of serum potassium,serum iron and total iron binding capacity of the peritonitis group were lower than those of the non-peritonitis group,and there were significant differences(all P＜0.05).The bina-ry logistic regression analysis indicated that glycosylated hemoglobin no less than 7.00％(OR=4.047,95％CI:1.663 to 9.847,P=0.002),no less than 60 years of age(OR=2.181,95％CI:1.039 to 4.578,P=0.039),triglyc-eride greater than 1.47 mmol/L(OR=2.393,95％CI:1.140 to 5.026,P=0.021)and serum iron less than 7.90μmol/L(OR=2.582,95％CI:1.188 to 5.608,P=0.017)were the risk factors for the PDAP in the type 2 diabe-tes mellitus patients complicated with renal anemia.CONCLUSIONS The glycosylated hemoglobin no less than 7.00％,no less than 60 years of age,triglyceride greater than 1.47 mmol/L and serum iron less than 7.90 μmol/L are the risk factors for PDAP in the type 2 diabetes mellitus patients complicated with renal anemia.The risk pre-diction model can be established based on the above factors,and the intervention measures should be actively taken so as to reduce the risk of PDAP and improve the quality of life.

Objective:To explore the efficacy of non-invasive prenatal testing (NIPT) of fetal free DNA in maternal peripheral blood in fetuses with increased nuchal translucency (NT).Methods:A retrospective analysis was conducted on 1 184 singleton pregnant women that underwent chromosomal microarray analysis (CMA) at Nanjing Drum Tower Hospital, Nanjing University Medical School from June 2014 to December 2022 due to fetal increased NT (≥3.0 mm). These subjects were categorized based on whether the increased NT was accompanied by other high-risk factors into isolated increased NT without advanced maternal age (further subdivided into 3.0 mm≤NT<3.5 mm, 3.5 mm≤NT<4.0 mm, and NT≥4.0 mm subgroups), isolated increased NT with advanced maternal age, increased NT with nasal bone abnormalities, increased NT with other soft markers, and increased NT with structural abnormalities groups. Assuming the sensitivity and specificity of NIPT and expanded NIPT at this center were both 100%, genomic abnormalities outside the detection range of NIPT or expanded NIPT were termed as residual risk of NIPT or expanded NIPT. Chi-square test and Bonferroni correction were used to compare the residual risks of NIPT and expanded NIPT among the three subgroups of isolated increased NT without advanced maternal age group. Results:(1) In the group of isolated increased NT without advanced maternal age: For the 3.0 mm≤NT<3.5 mm subgroup (329 cases), 19 abnormalities were detected by CMA [12 cases of chromosome aneuploidy, seven cases of pathogenic copy number variation (pCNV)], with residual risks of NIPT and expanded NIPT both at 2.1% (7/329). For the 3.5 mm≤NT<4.0 mm subgroup (173 cases), 29 abnormalities were detected by CMA (17 cases of chromosome aneuploidy, nine cases of pCNV, three cases of chromosome unbalanced translocation), with residual risks of NIPT at 8.1% (14/173) and expanded NIPT at 7.5% (13/173). For the NT≥4.0 mm subgroup (270 cases), CMA detected abnormalities in 70 cases (50 cases of chromosome aneuploidy, 16 cases of pCNV, three cases of unbalanced translocations, and one case of sex chromosome abnormality combined with pCNV). The residual risk of NIPT was 12.2% (33/270), and the residual risk of expanded NIPT was 7.0% (19/270). The residual risks of NIPT and expanded NIPT in the 3.0 mm≤NT<3.5 mm subgroup were lower than those in the 3.5 mm≤NT<4.0 mm and NT≥4.0 mm subgroups (Bonferroni correction, all P<0.017). (2) In the group of 92 cases with isolated increased NT and advanced maternal age, CMA detected abnormalities in 36 cases (29 cases of chromosome aneuploidy, five cases of pCNV, one case of trisomy 21 combined with sex chromosome abnormality, and one case of trisomy 18 combined with sex chromosome abnormality). The residual risk of NIPT was 7.6% (7/92), and that of expanded NIPT was 5.4% (5/92). (3) In the group of 49 cases with increased NT combined with nasal bone abnormalities, CMA detected abnormalities in 24 cases (23 cases of chromosome aneuploidy and one case of pCNV). The residual risks of NIPT and expanded NIPT were both 2.0% (1/49). (4) In the group of 26 cases with increased NT combined with other soft markers, CMA detected abnormalities in nine cases (six cases of chromosome aneuploidy, one case of pCNV, and two cases of chromosome unbalanced translocations). The residual risks of NIPT and expanded NIPT were both 11.5% (3/26). (5) In the group of 245 cases with increased NT combined with structural abnormalities, CMA detected abnormalities in 121 cases (107 cases of chromosome aneuploidy, seven cases of pCNV, four cases of chromosome unbalanced translocations, one case of trisomy 21 combined with trisomy 20, and two cases of trisomy 18 combined with sex chromosome abnormalities). The residual risk of NIPT was 16.7% (41/245), and that of expanded NIPT was 4.1% (10/245). Conclusions:For isolated NT≥3.5 mm or NT≥3.0 mm combined with other high-risk factors, chorionic villus sampling in early pregnancy can be recommended, advancing the timing of prenatal diagnosis from the second trimester to the first trimester. For fetuses with isolated 3.0 mm≤NT<3.5 mm, the 2.1% residual risk of chromosomal abnormalities should be fully informed during counseling, even if the risk of NIPT is low.

Objective:To explore the human epidermal growth factor receptor 2 gene(HER2) expression amplification in endometrial cancer (EC) with different p53 expression patterns based on molecular typing, as well as their correlation and impact on prognosis.Methods:A retrospective analysis was conducted on 282 patients with EC who underwent surgical treatment at Dalian Women and Children′s Medical Center (Group) from January 2016 to December 2018 with complete clinical and pathological data. Immunohistochemistry and fluorescence in situ hybridization were used to detect the amplification of HER2 gene expression in paraffin- embedded tumor tissue of patients after surgery and confirmed the expression of p53. The clinical data were collected and tracked follow-up.Results:There were significant differences between HER2-positive patients and HER2-negative patients in the age of onset, pathological types of tumor tissue, depth of muscle infiltration, and tumor differentiation ( P< 0.05). The 5-year survival rate and 5-year progression-free survival rate of HER2-positive patients were lower than those of HER2-negative patients (45.45% vs. 95.16%, 45.45% vs. 95.11%), and there were statistical differences ( P<0.01). The positive expression of HER2 in EC tissues was positively correlated with p53 mutant expression ( r = 0.409, P<0.01). Among p53 wild-type EC patients, the 5-year survival rate was 98.4% for HER2-negative patients and 100.00% for HER2-positive patients. In the patients with p53 mutant EC, 58.05% and 37.50%, respectively, there was a statistical difference ( P<0.01). The 5-year progression-free survival rates were 97.50%, 100.00%, 60.20%, and 37.50%, respectively, and there was a statistical difference ( P<0.01). Conclusions:There is a significant positive correlation between HER2 positive overexpression and p53 mutant expression in EC tissue, and there is an inherent synergy between the two expressions. HER2 positive over expression is a key factor for poor prognosis in EC patients. Patients with HER2- positive over expression and p53 mutant expression have poorer 5-year overall survival and progression- free survival compared to other groups.

Objective In this study,the potential profile characteristics of exercise self-efficacy of patients with inflammatory bowel disease(IBD)were explored,and the influencing factors of different types of patients were an-alyzed,so as to provide a reference for nurses to formulate standardized management measures.Methods From June 2023 to May 2024,a total of 342 hospitalized patients with IBD in tertiary A hospital in Wuxi were recruited as research subjects by a convenience sampling method.The General Information Questionnaire,Exercise Self-effica-cy Scale,Exercise Behavioral Stage Distribution Scale and the Social Support Rating Scale were used for investiga-tion.The latent profile analysis was conducted to classify exercise self-efficacy levels,while multiple Logistic regres-sion analysis was utilized to evaluate the influencing factors.Results A total of 320 valid questionnaires were col-lected,and the effective questionnaire recovery rate was 93.57％.The total score of exercise self-efficacy for IBD pa-tients was(64.61±14.83)points.The exercise self-efficacy was classified into 3 latent categories:low efficacy-somatic emotion group(n=64,20.00％),medium efficacy-work conflict group(n=158,49.38％),and high efficacy-social interfer-ence group(n=98,30.62％).Occupation,recurrence times,comorbid chronic diseases,self-assessed economic pressure,and social support level were found to be influencing factors of the latent profile classification of exercise self-effi-cacy in IBD patients(P＜0.05).Conclusion The levels of exercise self-efficacy of patients with IBD are significant-ly heterogeneous,and there are several important influencing factors.Nursing staff should formulate targeted inter-vention strategies based on the characteristics of exercise self-efficacy in such patients,so as to improve patients' exercise self-efficacy and the effectiveness of disease rehabilitation.
