【Objective】 To explore the effectiveness of an image recognition system based on artificial intelligence (AI) in diagnosing benign and malignant endometrial cell clumps. 【Methods】 We selected endometrial cytological specimens from The First Affiliated Hospital of Xi’an Jiaotong University and Xi’an Daxing Hospital from August 2021 to February 2023; histopathology was used as the gold standard. We compared and analyzed the sensitivity, specificity, positive predictive value, negative predictive value, accuracy and diagnostic time of AI image recognition system (AI diagnosis) and professional pathologists’ manual diagnosis (manual diagnosis) of benign and malignant endometrial cell clumps. 【Results】 Among the 126 patients included in the analysis, the overall coincidence rate of AI diagnosis and histological diagnosis was 92.1% (116/126), which was highly consistent with histopathological results (Kappa=0.841). The overall coincidence rate of manual diagnosis and histological diagnosis was 94.4% (119/126), which was highly consistent with histopathological results (Kappa=0.889). There was no statistically significant difference between AI diagnosis and manual diagnosis methods (χ²=0.568, P=0.451). The sensitivity, specificity, positive predictive value, and negative predictive value of AI diagnosis were 91.8%, 92.3%, 91.8%, and 92.3%, respectively. There were 126 cytology sections, each of which required 6.67 minutes for manual diagnosis and 5.00 minutes for AI diagnosis. 【Conclusion】 The AI image recognition system has high diagnostic accuracy, sensitivity and specificity, which is equivalent to the manual diagnosis level of professional pathologists. Therefore, this system has application value in the diagnosis of benign and malignant endometrial cell clumps.

BACKGROUND:The pedicle navigation template has many advantages,but there are still some problems.For example,poor soft tissue dissection leads to poor adhesion of the pedicle navigation template,resulting in screw path deviation;careful dissection of soft tissue to fit the pedicle navigation template leads to prolonged surgery time and increased bleeding;the design of the pedicle navigation template cannot predict the vertebral rotation and the impact of body position changes,resulting in the poor fitting. OBJECTIVE:To explore the utility of a new 5-point positioning point-contact pedicle navigation template in the case of scoliosis and complex pedicle. METHODS:A total of 20 patients with scoliosis and complicated pedicle admitted to the Department of Spinal Surgery,Guizhou Hospital,Beijing Jishuitan Hospital from February 2020 to February 2023 were selected for scoliosis orthopedics.During the operation,the 5-point positioning point-contact pedicle navigation template was used to guide the screws.According to the inclusion and exclusion criteria,34 cases were matched as the empirical nail placement group,and conventional barehanded nail placement was performed.The time of placement,the amount of bleeding,the number of fluoroscopies,the number of manual diversions,the level and accuracy of pedicle screws,the complications of placement,and the rate of correction of main curvature were compared between the two groups. RESULTS AND CONCLUSION:(1)There were no significant differences in sex,age,coronal Cobb's angle of the main curvature,bending Cobb's angle of the main curvature,pedicle variation,apex rotation,fusion segment,number of screws,level of screws,accuracy of screws,and rate of correction of main curvature between the navigation template group and the empirical nail placement group(P>0.05).(2)Compared with the empirical nail placement group,the navigation template group had more advantages in time of placement(P=0.034),amount of bleeding(P=0.036),number of fluoroscopies(P=0.000)and number of manual diversions(P=0.021).(3)There were 0 cases of screw-related complications in both groups.(4)In conclusion,the 5-point positioning point-contact 3D printing pedicle navigation template has a claw-like structure.It can firmly adapt to various deformities of the lamina articular process,avoid drift,and accurately place the screws.It has a point-like contact lamina structure to avoid extensive and complete dissection of the posterior structure,and reduce bleeding,operation time,and trauma.Pre-designed screw entry points and directions can reduce the number of fluoroscopy and operation time.Segmental design can avoid discomfort due to changes in anesthesia position.The operation is simple and the accuracy of screw placement is high.

In the aftermath of the pandemic,the government is accelerating the development of top-tier medical resources to broaden the supply and deliver superior healthcare services.However,during this transitional phase,hospitals are experiencing operational challenges due to concurrent construction activities.Notably,a shortage of parking facilities and increased traffic con-gestion continue to impactmedial consultation experience of patients.This paper tries to explore strategies and methods for dynam-ic parking management during hospital campus expansions,offering insights for other medical institutions into grappling with pa-tient parking issues.

Objective:To evaluate the efficacy and safety of albumin bound paclitaxel(nab-PTX)and solvent based paclitaxel(sb-PTX)in neoadjuvant chemotherapy(NACT)for advanced epithelial ovarian cancer(EOC).Methods:A retrospective analysis was conducted on the clinical data of 107 patients with advanced EOC who un-derwent preoperative NACT in the First Affiliated Hospital of Xi'an Jiaotong University from June 11,2018 to Sep-tember 19,2023.Among them,52 patients were treated with nab-PTX combined with carboplatin intravenous chemotherapy(nab-PTX group),and 55 with sb-PTX combined with carboplatin intravenous chemotherapy(sb-PTX group).The clinical indicators after NACT,intraoperative conditions of cytoreductive surgery and ad-verse events during the NACT were compared in two groups.Results:The maximum tumor diameter(3.7 cm vs.3.8 cm),CA125(28.9 U/ml vs.31.6 U/ml)and HE4(102.5 U/ml vs.119.0 U/ml)levels in the nab PTX group after NACT were significantly lower than those in the sb-PTX group,and the differences were statistically significant(P＜0.001).After NACT,the total input(2580 ml vs.2100 ml),the proportion of surgical complexity score(36.54％vs.18.18％),and lymph node resection rate(57.69％vs.29.09％)in the nab-PTX group were significantly higher than those in the sb-PTX group(P＜0.05).There was no statistically significant difference(P＞0.05)in the amount of ascites,clinical efficacy evaluation,ORR,DCR,surgical time,intraoperative bleeding,total output,postoperative hospital stays,surgical satisfaction,pathological complete response rate(pCR),transfu-sion of blood products,lymph node metastasis and adverse effects during NACT between the two groups.Con-clusions:Nab-PTX has a better clinical disease control effect than sb-PTX in NACT,in order to achieve better cy-toreductive surgery,but it has no significant effect on pathological remission.The safety of the two drugs is similar.
