Cerebral palsy in children is a motor developmental disorder caused by non-progressive brain damage occurring prenatally,perinatally,or postnatally,with the spastic type being the most common clinical manifestation.This article systematically introduces Qin Min's academic philosophy in treating spastic cerebral palsy using Lingnan Flying Needle Therapy based on the Inner Canon's theory of"maintaining patency of qi and meridians".It elaborates on the core pathogenesis of"deficiency and stagnation of qi and meridians,leading to malnourishment of tendons and vessels"and the treatment approach of"regulating the conception vessel and governor vessel to unblock qi and meridians".By employing characteristic needling techniques such as Lingnan scalp acupuncture and Lingnan abdominal-back acupuncture,the therapy aims to activate yang qi,regulate and unblock qi and meridians,thereby achieving the goals of nourishing the spirit,softening tendons,and balancing yin and yang,with demonstrated favorable clinical efficacy.

Objective:To compare the efficacy of Union Plate combined with robotic placement of infra-acetabular and posterior column screws and common reconstruction plate combined with freehand placement of infra-acetabular and posterior column screws in the treatment of complex acetabular fractures.Methods:The data of 42 patients with complex acetabular fractures treated in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June 2020 to June 2023 were retrospectively analyzed. Among them, 22 patients were treated with Union Plate combined with robotic placement of posterior column screws and infra-acetabular screws (Union Plate robot group). 20 cases were treated with common reconstruction plate combined with posterior column screw and infra-acetabular screw fixation by hand (reconstruction plate freehand group). The Union Plate robot group included 16 males and 6 females, aged 43.7±11.6 years (range, 24-67 years). Letournel-Judet classification: 14 cases of double-column fractures, 5 cases of anterior column with posterior semi-transverse fractures, 3 cases of "T" -shaped fractures. There were 15 males and 5 females in the reconstruction plate freehand group, aged 42.9±12.0 years (range, 22-66 years). Letournel-Judet classification: 15 cases of double-column fractures, 3 cases of anterior column with posterior semi-transverse fractures, 2 cases of "T" -shaped fractures. The operative time, intraoperative blood loss, intraoperative fluoroscopy times, frame screw placement time, fracture healing time, perfect frame screw placement rate (grade 0 rate) assessed according to the Lonstein criteria, reduction quality assessed according to the Matta criteria, the modified Merle d'Aubign-Postel score and postoperative complications were compared between the two groups.Results:All 42 patients were followed up for 10 to 30 months, with an average of 13 months. The fracture healing time was 3.4±0.4 months in the Union Plate robot group and 3.6±0.4 months in the reconstruction plate freehand group, with no statistical significance ( t=2.179, P=0.035). The operative time and intraoperative blood loss of the Union Plate robot group were 138.3±30.7 min and 735.7±159.8 ml, respectively, which were lower than 163.9±48.7 min and 843.5±181.1 ml in the reconstruction plate freehand group. The differences were statistically significant ( P<0.05). The time and intraoperative fluoroscopy times of the Union Plate robot group were 19.9±3.2 min and 17.1±4.9 times, respectively, which were less than 42.5±6.7 min and 45.4±4.9 times of the reconstruction plate freehand group, and the differences were statistically significant ( P<0.05). According to the Lonstein evaluation, there were 42 cases of class 0 and 2 cases of class I in the Union Plate robot group, and the perfect frame screw placement rate was 96%(42/44). There were 30 cases of grade 0, 8 cases of grade I and 2 cases of grade II in the reconstruction plate freehand group, and the perfect frame screw placement rate was 75%(30/40). There was significant difference between the two groups (χ 2=7.426, P=0.024). According to the Matta criteria, 15 cases of Union Plate robot group were excellent, 4 cases were good, and 3 cases were poor, with an excellent and good rate of 86%(19/22). In the reconstruction plate free hand group, 13 cases were excellent, 4 cases were good, and 3 cases were poor, with an excellent and good rate of 85%(17/20). There was no significant difference between the two groups (χ 2=0.048, P=0.976). At the last follow-up visit, the modified Merle d'Aubign-Postel score of the Union Plate robot group was 16.9±1.7 points and that of the reconstruction plate freehand group was 16.5±2.2 points, with no statistical significance ( t=0.593, P=0.557). In the Union Plate robot group, wound fat liquefaction and lateral femoral cutaneous nerve injury occurred in 1 case, the complication rate was 9%(2/22). There were 4 cases of fat liquefaction, 1 case of lateral femoral cutaneous nerve injury, and 1 case of traumatic hip arthritis in the reconstruction plate freehand group. The complication rate was 30%(6/20), and the difference in complication rate was not statistically significant (χ 2=1.769, P=0.183). Conclusions:The clinical efficacy of Union Plate combined with robotic placement of posterior column screws and infra-acetabular screws in the treatment of complex acetabular fractures is comparable to that of reconstruction plate combined with freehand placement of posterior column screws and infra-acetabular screws. However, the use of Union Plate combined with robotic placement of frame screws can shorten the operative time and the time of frame screw placement. The amount of intraoperative blood loss and intraoperative fluoroscopy times were reduced, and the accuracy of frame screw placement was higher.

Venous system diseases mainly include varicose veins and venous malformations of lower limbs and the genital system. Most of them are chronic diseases that cause serious clinical symptoms to patients and affect their health and quality of life. Sclerotherapy has become the first-line therapy for venous system diseases. However, there are problems such as incomplete fibrosis and vascular recanalization after sclerotherapy, and improper operation will cause serious adverse consequences. Therefore, exploring a safe and effective sclerotherapy strategy is essential for developing clinically successful sclerotherapy. To solve the above problems, we proposed a new sclerotherapy strategy with a dual mechanism of "vascular damage and plasmin (PLA) system inhibition." We intended to construct a novel cationic surfactant (AEO_x-TA) by reacting tranexamic acid (TA), a parent structure, with fatty alcohol polyoxyethylene ether (AEO_x) by ester bonds. AEO_x-TA could damage vascular endothelium and initiate a coagulation cascade effect to induce thrombus. Furthermore, AEO_x-TA could be degraded by esterase and release the parent drug, TA, which could inhibit the PLA system to inhibit the degradation of thrombus and extracellular matrix and promote the process of vascular fibrosis. In addition, such surfactant-based sclerosants have foam-forming properties, and they can be blended with polyvinyl alcohol (PVA) to prepare a highly stable foam formulation (AEO_x-TA/P), which can achieve a precise drug delivery and prolonged drug retention time, thereby improving drug efficacy and reducing the risk of ectopic embolism. Overall, the novel cationic surfactant AEO_x-TA provides a new avenue to resolve the bottleneck: surfactant sclerosants' efficiency is relatively low in the current sclerotherapy.

Objective:To investigate the efficacy and safety of the "frame and buttress" fixation in the treatment of acetabular quadrilateral fractures.Methods:A total of 26 patients with acetabular quadrilateral fractures treated with the "Frame and buttress" fixation strategy (reconstructing frame and providing buttress for quadrilateral surface) from January 2017 to January 2021 were retrospectively analyzed in the Department of Orthopaedics, Union Hospital of Tongji Medical College, Huazhong University of Science and Technology, including 17 males and 9 females, aged 47.7±16.5 years, (range, 25-71 years). There were 13 cases from car accidents, 8 cases from falls, and 5 cases from heavy objects. Quadrilateral fractures were classified according to whether the anterior column (A) and posterior column (P) of the acetabulum were fractured and whether the quadrilateral plate (Q) was partially (1) or completely (2) separated from the two columns. Among these cases, there were 5 cases of type AQ1, 1 case of type AQ2, 1 case of type PQ2, 14 cases of type APQ1 and 5 cases of type APQ2. The "frame and buttress" fixation strategy was used to perform open reduction and internal fixation. The Matta scale was used to assess the quality of resurfacing based on pelvic radiographs, and the Matta modified Merle d'Aubigne and Postel scores were referenced to evaluate hip function.Results:All the 26 patients successfully completed the operation, the operation time was 88.1±57.8 min (range, 90-320 min), the intraoperative bleeding was 753.8±309.5 ml (range, 400-1 400 ml). There were 14 cases of anatomical reduction, 8 cases of satisfactory reduction and 4 cases of unsatisfactory reduction with an excellent rate of 85% (22/26), the excellence rate was 85% (22/26). All patients were followed up for 16.3±4.3 months (range, 12-24 months). The hip function score after operation was higher than that before operation, and the difference was statistically significant ( F=19.80, P<0.001). The hip function score was 13.1±2.2 at 3 months postoperatively, increased to 15.9±2.3 at 6 months postoperatively, and increased to 16.6±1.9 at the last follow-up, with a statistically significant difference ( P<0.001). After operation, 5 patients showed symptoms of lateral femoral cutaneous nerve injury such as hypoesthesia and numbness in the anterolateral thigh. During the follow-up, there was no ectopic ossification, traumatic arthritis, necrosis of the femoral head and central dislocation of the femoral head. Conclusion:The "frame and buttress" fixation strategy based on quadrilateral fracture typing for acetabular quadrilateral fracture open reduction internal fixation provides strong fixation, satisfactory reduction quality, and facilitates joint function recovery after operation.
