OBJECTIVE: To investigate the effectiveness of digital three-dimensional (3D) printing osteotomy guide plate assisted total knee arthroplasty (TKA) in treatment of knee osteoarthritis (KOA) patients with femoral internal implants. METHODS: The clinical data of 55 KOA patients who met the selection criteria between July 2021 and October 2023 were retrospectively analyzed. Among them, 26 cases combined with femoral implants were treated with digital 3D printing osteotomy guide plate assisted TKA (guide plate group), and 29 cases were treated with conventional TKA (control group). There was no significant difference in gender, age, body mass index, side, Kellgren-Lawrence classification, preoperative visual analogue scale (VAS) score, Hospital for Special Surgery (HSS) knee score, knee range of motion, and other baseline data between the two groups ( P>0.05). The operation time, intraoperative blood loss, incision length, postoperative first ambulation time, surgical complications; VAS score, knee HSS score, knee range of motion before operation, at 1 week and 3 months after operation, and at last follow-up; distal femoral lateral angle, proximal tibial medial angle, hip-knee-ankle angle and other imaging indicators at last follow-up were recorded and compared between the two groups. RESULTS: The operation time, incision length, intraoperative blood loss, and postoperative first ambulation time in the guide plate group were significantly lower than those in the control group ( P<0.05). In the control group, there were 1 case of incision rupture and bleeding and 1 case of lower limb intermuscular venous thrombosis, which was cured after symptomatic treatment. There was no complication such as neurovascular injury, incision infection, or knee prosthesis loosening in both groups. Patients in both groups were followed up 12-26 months, with an average of 16.25 months. The VAS score, HSS score, and knee range of motion improved at each time point after operation in both groups, and further improved with time after operation, the differences were significant ( P<0.05). The above indicators in the guide plate group were significantly better than those in the control group at 1 week and 3 months after operation ( P<0.05), and there was no significant difference between the two groups at last follow-up ( P>0.05). At last follow-up, the distal femoral lateral angle, the proximal tibial medial angle, and the hip-knee-ankle angle in the guide plate group were significantly better than those in the control group ( P<0.05). CONCLUSION The application of digital 3D printing osteotomy guide plate assisted TKA in the treatment of KOA patients with femoral implants can simplify the surgical procedures, overcome limitations of conventional osteotomy guides, reduce surgical trauma, achieve individualized and precise osteotomy, and effectively restore lower limb alignment and knee joint function.

Objective Comparative analysis of rule categories,key audit behaviors,and the degree of correspon-dence between rules and behaviors through intelligent auditing of key audit violations and monitoring of the rule base.To provide reference for the improvement of intelligent audit and monitoring rule library for key audit violations under DRG payment in medical insurance fund.Methods Searching and collecting policy documents such as DRG payment management methods issued by local health insurance bureaus from May 20,2019 to December 31,2023 and the literature related to DRG payment smart audit monitoring rules in the database,and targeting the rules therein that are related to the focus on auditing irregularities under the DRG payment.Literature analysis and comparative analysis were used to summarize and analyze the rules related to key audit violations under DRG payment.Results The intelli-gent audit rules for key audit violations under DRG payment can be divided into two major categories:logical judg-ment and parameter index,and the degree of correspondence between audit rules and key audit behaviors varies.Conclusion(1)Unify the key audit rules nationwide to ensure the universality and comprehensiveness of the rules;(2)Deepen the current situation of regional illegal activities and strengthen local characteristics;(3)Improve the quality of logical judgment rules and increase the quantity of parameter indicator rules;(4)Strengthen scientific re-search on new types of violations,and establish more targeted regulatory rules.

Purpose To evaluate the differential diagnostic value of conventional ultrasound in the ureteral polyps and ureteral carcinoma via continuous observation.Materials and Methods The conventional ultrasound of patients with ureteral polyps and ureteral carcinoma treated in Shaanxi Provincial People's Hospital were retrospectively analyzed from June 2015 to June 2022.According to the pathological results,all participants were divided into the ureteral polyp group(98 cases)and the ureteral carcinoma group(151 cases).All clinical and ultrasound data were recorded,and the differences of echo,blood flow and peristalsis were compared between the two groups.Results There were significant differences in ureteral peristalsis,color Doppler flow distribution,periureteral tissue thickening,increased echo,and hydronephrosis(χ2=197.50,138.89,26.97,36.13,all P<0.05)between the two groups.Low echo was predominant in both groups[67(68.37)vs.114(75.50)],with no significant difference(χ2=1.52,P>0.05).In the ureteral polyp group,67 cases were found in the upper ureter,89 cases were observed continuously with common peristalsis,and 73 cases with color blood flow were mostly central blood flow,while in the ureteral cancer group,85 cases were found in the middle and lower ureter,148 cases showed almost no peristalsis,and 122 cases with color blood flow were mostly peripheral blood flow.Conclusion There are some differences in clinical features such as the location as well as whether hydronephrosis between ureteral polyps and carcinoma.Peristalsis can provide the differential diagnosis for ureteral polyps and ureteral carcinoma via continuous observation.
