This paper reviews the published articles of recent years on the application of deep learning methods in automatic localization of acupoint, and summarizes it from 3 key links, i.e. the dataset construction, the neural network model design, and the accuracy evaluation of acupoint localization. The significant progress has been obtained in the field of deep learning for acupoint localization, but the scale of acupoint detection needs to be expanded and the precision, the generalization ability, and the real-time performance of the model be advanced. The future research should focus on the support of standardized datasets, and the integration of 3D modeling and multimodal data fusion, so as to increase the accuracy and strengthen the personalization of acupoint localization.

Objective:To compare the therapeutic efficacy of the dual anteromedial and anterolateral approaches versus that of the anterior midline approach in the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse.Methods:A retrospective study was conducted to analyze the 21 patients who had been treated for Wahlquist type C medial tibial plateau fractures plus posterior column collapse at The Fourth Orthopedic Ward, The 72nd Group Army Hospital of PLA between January 2019 and August 2023. The cohort included 13 males and 8 females, with an age of (43.3±6.7) years. The left side was involved in 14 fractures and the right side in 7 ones. The patients were divided into 2 groups based on their surgical approaches: a dual-approach group ( n=13) undergoing fixation via the dual anteromedial and anterolateral approaches, and a single-approach group ( n=8) undergoing fixation via the anterior midline approach. Comparative parameters included operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, medial proximal tibial angle (MPTA), incision complications, postoperative bone mass reduction quality (evaluated according to the Rasmussen anatomical criteria for tibial condyle fracture reduction), lateral tibial plateau instability, incidence of genu varum, and post-traumatic arthritis. Functional recovery of the lower limb joints was assessed at the final follow-up using the Merchant criteria. Results:No statistically significant differences were observed in the baseline characteristics between the 2 groups preoperatively, indicating comparability ( P>0.05). All patients were followed up for a mean duration of (38.1±11.3) months. The postoperative MPTA in the dual-approach group (86.8°±0.8°) was significantly larger than that in the single-approach group (85.5°±0.9°) ( P<0.05). Genu varum occurred in 1 patient in the dual-approach group and in 4 patients in the single-approach group, while lateral tibial plateau instability was observed in 1 patient in the dual-approach group and in 4 patients in the single-approach group, showing statistically significant differences between the 2 groups ( P<0.05). No statistically significant differences were found between the 2 groups regarding operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, incidence of incision complications, or incidence of post-traumatic arthritis ( P>0.05). At the final follow-up, no statistically significant difference was observed in the functional recovery of the lower limb joints assessed by the Merchant criteria between the 2 groups ( P>0.05). Conclusion:In the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse, compared with the single anterior midline approach, the dual anteromedial and anterolateral approaches can restore more effectively the MPTA, and reduce the incidences of genu varum and lateral tibial plateau instability.

Objective To explore the feasibility of establishing a swine model of liver cirrhosis with portal hypertension by portal infusion of 80％ alcohol.Methods A total of 13 Guizhou miniature pigs were randomly divided into three groups,experiment group 1 (n=5),experiment group 2 (n=5) and control group (n=3).Experiment groups of pigs received portal infusion of 80％ alcohol in volumes of 5 ml in group 1,and 10 ml in group 2,and the pigs in control group received portal perfusion of saline in volumes of 10 ml.All animals were performed direct portal angiography,the portal vein pressures and diameter were also detected before,immediately and 6 weeks after the infusion.All animals underwent liver biopsies before and 6 hours,1-6 weeks after operation.And contrast-enhanced abdominal CT was performed before and 6 weeks after operation.All animals were dissected 6 weeks after operation,aud each leaf of liver specimens were performed histological examination.Results There was no statistically significant difference of the portal venous pressure and diameter before infusion and 6 weeks after infusion in the experiment group 1 and control group (all P＞0.05).In the experiment group 2,compared with pre infusion,the portal vein pressure and diameter were higher than those of immediately and 6 weeks after infusion (all P＜0.05).In both experiment group 1 and group 2,all pigs had developed into liver fibrosis,the METAVIR score of 2 pigs in group 1 and 5 pigs in group 2 respectively were up to grade 4.Conclusion Portal infusion of 80％ alcohol is more suitable for establishing a swine model of liver cirrhosis with portal hypertension.

Objective To investigate the value of the flow cytometry(FCM)for detecting platelet associated antibody in the di-agnosis of immune thrombocytopenia(ITP).Methods Platelet associated antibody,expression rate and the fluorescence intensity of platelet-associated immunoglobulin(PAIg)were measured in 51 patients with ITP(23 cases of newly diagnosed ITP and 28 cases of persistent ITP),21 patients with non-ITP and 60 healthy individuals.The correlation between the detection results with the platelet and megakaryocyte counts was performed;the expression rates of PAIg before and after treatment were compared.Results The fluorescence positive percentage and mean fluorescence intensity of IgG,Ig A and IgM in the patients group were significantly high-er than those in the control group with statistical difference(P <0.01).Compared with the non-ITP group,the difference had statis-tical significance(P <0.05).Compared with the autoimmune disease group,the difference had no statistical significance(P >0.05);the difference between the autoimmune disease group and the healthy control group had statistical significance(P <0.01 );in the persistent ITP group,PAIg in the complete response group had statistical difference between the groups before treament.PAIg in the response group also had statistical difference between the groups before treament (P <0.05).Conclusion FCM for detecting PAIg can be used in the diagnosis,differential diagnosis and the disease condition monitoring of ITP.
