Objective: To probe the best therapy for peripheral facial paralysis. Methods: A total of 122 cases of facial paralysis patients were randomized into treatment group (n=62, treating the disease by stages) and control group (n=60). For patients at the acute stage in treatment group, main point Yifeng (TE 17) was pricked first, followed by performing cupping and moxibustion, for patients at the resting stage, main point Hegu (LI 4) was punctured with reducing needling method, combined with other acupoints in the light of the concrete situations. For patients at the restoration stage, main point Zusanli (ST 36) was punctured with reinforcing method in combination with seven-star-needle tapping at the local affected region. Patients of control group were treated with routine method by puncturing Fengchi (GB 20), Yifeng (TE 17), Jiache (ST 6), Hegu (LI 4), Taichong (LR 3), etc.. The treatment was conducted once daily, with 10 days being a therapeutic course. Results: Following 3 courses of treatment, of the 62 cases in treatment group, 44 (70.9%) were cured, 12 (19.4%) had remarkable improvement in their symptoms and signs, 6 (9.7%) had amelioration, with the cure plus markedly effective rate being 90.3%; of the 60 cases in control group, 30 (50.0%) were cured, 12 (20.0%) had apparent improvement, 16 (26.7%) had amelioration, and the rest 2 (3.3%) failed in the treatment, with the cure plus markedly effective rate being 70.0%. Ridit analysis showed that the cure rate and cure plus markedly effective rate of treatment group were significantly higher than those of control group (P0.05). Conclusion: Stage-aided acupuncture treatment is superior to routine treatment for facial palsy.
Aims The morphology of medial malleolar fracture is highly variable and difficult to characterize without 3D reconstruction. There is also no universally accepeted classification system. Thus, we aimed to characterize fracture patterns of the medial malleolus and propose a classification scheme based on 3D CT reconstruction. Methods We retrospectively reviewed 537 consecutive cases of ankle fractures involving the medial malleolus treated in our institution. 3D fracture maps were produced by superimposing all the fracture lines onto a standard template. We sliced fracture fragments and the standard template based on selected sagittal and coronal planes to create 2D fracture maps, where angles α and β were measured. Angles α and β were defined as the acute angles formed by the fracture line and the horizontal line on the selected planes. Results A total of 121 ankle fractures were included. We revealed several important fracture features, such as a high correlation between posterior collicular fractures and posteromedial fragments. Moreover, we generalized the fracture geometry into three recurrent patterns on the coronal view of 3D maps (transverse, vertical, and irregular) and five recurrent patterns on the lateral view (transverse, oblique, vertical, Y-shaped, and irregular). According to the fracture geometry on the coronal and lateral view of 3D maps, we subsequently categorized medial malleolar fractures into six types based on the recurrent patterns: anterior collicular fracture (27 type I, 22.3%), posterior collicular fracture (12 type II, 9.9%), concurrent fracture of anterior and posterior colliculus (16 type III, 13.2%), and supra-intercollicular groove fracture (66 type IV, 54.5%). Therewere three variants of type IV fractures: transverse (type IVa), vertical (type IVb), and comminuted fracture (type IVc). The angles α and β varied accordingly. Conclusion Our findings yield insight into the characteristics and recurrent patterns of medial malleolar fractures. The proposed classification system is helpful in understanding injury mechanisms and guiding diagnosis, as well as surgical strategies. Cite this article: Bone Joint J 2021;103-B(5):931–938.
The challenge for functional magnetic resonance imaging (fMRI) is to determine when and where the response due to an external stimulus occurs in the images. The temporal clustering analysis (TCA) method has been used to study brain activity after eating and drinking, in both the time and spatial domains. We propose a new method, competitive subspace projection (CSP), to represent data optimally compared to other subspace projection methods. This method is used to detect spatial and temporal activation patterns in fMRI associated with such behavior. The CSP and TCA methods are compared using both synthetic and real fMRI data. The results on both data sets show consistent conclusions can be drawn from these two methods while CSP is observed to have a better noise rejection capability than TCA.
Among patients undergoing elective non-cardiac surgery (NCS), those with coronary stent implants are gradually becoming a patient group that cannot be easily overlooked. Previous history of heart disease, coronary stents and antiplatelet agents expose these patients to dual perioperative risks of thrombosis and bleeding. Formulating appropriate plans for perioperative antiplatelet therapy will help reduce the risks and ensure the safety of patients. We herein reviewed and analyzed various aspects of perioperative antiplatelet therapy for patients with coronary stent implants undergoing elective NCS, and discussed prospective research directions in the field.
Objective: To introduce a new method of reestablishing blood supply for reconstructed thumb or fingers. Methods: According to the anatomic features of the distal radial artery, the superficial palmar branch and the end branch of the radial artery were anastomosed with the arteries of transplanted tissues during the operation of thumb or finger reconstructing. Results: In total 15 cases, the transferred flaps survived well, and the reconstructed thumb or finger showed satisfied appearance and function, accompanying with fine sensory recovery. Conclusions: The method is simple and practical, the survive rate of anastomosing blood vessel is high. The transplanted tissues have independent blood supply, which means that blood supply from different transplanted tissues will not be affected even unexpected accidents happened in one group vessels.
Objective
To investigate the significance of tumor markers CEA and CA19-9 in predicting the clinicopathologic characteristics and prognosis of primary duodenal carcinoma.
Methods
A retrospective analysis of 110 cases with primary duodenal carcinoma treated in our hospital from January 1999 to December 2016 was conducted. ROC analysis, univariate and multivariate analysis were performed to investigate the relationship between CEA, CA19-9 and the clinicopathologic characteristics of primary duodenal carcinoma. Kaplain-Meier method was used to analyze the relationship between CEA and CA19-9 and the prognosis of primary duodenal carcinoma.
Results
CEA level was of value for predicting the depth of infiltration, lymphatic involvement, metastasis and TNM stage. The receiver operating characteristic was 0.629, 0.672, 0.749, 0.692 respectively. Univariate analysis showed serum CA19-9 lever was related to the depth of infiltration and serum CEA lever were related to tumor differentiation, lymphatic invasion, metastasis and TNM stage. Logistic analysis showed that CEA value was only associated with metastasis (OR: 9.853, P<0.01). Patients with elevated serum CEA level had a significant worse prognosis than patients with normal serum CEA level(P<0.05).
Conclusion
Serum CEA level was closely associated with the clinicopathologic characteristics and prognosis of primary duodenal carcinoma.

Abstract Background Hip fractures have become a severe public health problem, especially in very elderly patients. Most of them are treated with low molecular weight heparin as prophylaxis or treatment of venous thromboembolism. Heparin-induced thrombocytopenia is one of the complications induced by low molecular weight heparin, which may cause poor prognosis. However, there is not enough awareness for heparin-induced thrombocytopenia in very elderly trauma patients. Case presentation We report a case of hip fracture with heparin-induced thrombocytopenia in a very elderly patient. The patient developed heparin-induced thrombocytopenia, digestive hemorrhage and acute colonic pseudo-obstruction after the use of low molecular weight heparin, which eventually led to death. Conclusions This is the first case report of digestive hemorrhage and acute colonic pseudo-obstruction in heparin-induced thrombocytopenia patients with major trauma. This case highlights the severity of HIT in very elderly patients with hip fractures using low molecular weight heparin, and the need for platelet monitoring in these patients. We indicate that there may be a correlation of pathogenesis between digestive hemorrhage and acute colonic pseudo-obstruction in heparin-induced thrombocytopenia patients.
Intraarticular impacted fragment (IAIF) of posterior malleolar fractures has been reported by a few studies. However its location, morphology, and the correlation of posterior malleolar fractures have not been described in detail. The aim of this study was to describe the morphology of IAIF in posterior malleolar fractures, to analyze the related factors between IAIF and posterior malleolar fragments, and explore the treatment of IAIF.Between January 2013 and December 2018, 108 consecutive patients with unilateral posterior malleolar fractures were managed in our hospital. Basic demographic and computed tomography (CT) data were collected and classified by Lauge-Hansen, OTA/AO, Haraguchi, and Mason classification. Additional radiographic data, including the length and area of posterior malleolar fragment, IAIF, and stable tibial plafond were measured. The location of IAIF was described, and involvement of the fibular notch and medial malleolus was also observed. Statistics were analyzed based on univariate analysis (Chi-square test, t-test, Mann-Whitney U test, Fisher's test) and Spearman's correlation test.Among the 108 cases of posterior malleolar fractures, 75 (69.4%) were with IAIF and 33 (30.6%) cases were without. There were 74 (68.5%) females and 34 (31.5%) males, and the average age of the patients was 49 years (18-89 years). The average LIFN/(LIFN + LSFN) [length of involving fibular notch/(length of involving fibular + length of stable notch fibular notch)] was 32.9% (11.6-64.9%). The APMF/(APMF + ASTP + AIAIF) [area of posterior malleolar fragment/(area of posterior malleolar fragment + area of IAIF + area of stable tibial plafond)] and AIAIF/APMF (area of IAIF/area of posterior malleolar fragment) were 13.1% (0.8-39.7%) and 52.6% (1.2-235.4%), respectively. Involvement of medial malleolus (fracture line extended to medial malleolus, P = 0.022), involvement of fibular notch (P = 0.021), LIFN/(LIFN + LSFN) (P = 0.037), LMPMF (P = 0.004), and APMF were significantly related to the occurrence of IAIF.Our research indicates a high incidence of IAIF in posterior malleolar fractures. All IAIFs were found in posterior malleolar, and the most common location was within the lateral area A. Posterior malleolar fracture lines that extend to medial malleolus or fibular notch herald the incidence of IAIF. LIFN/(LIFN + LSFN), LMPMF and APMF are also associated with the incidence of IAIF. CT scans are useful for posterior malleolar fractures to determine the occurrence of IAIF and make operational plans. Operation approach selection should be based on the morphology of posterior malleolar fragments and the location of IAIF.Level III, retrospective case analysis.
Objective There is a new medial malleolar fracture classification based on 3D CT reconstruction. However, there is no study assessing the reliability and accuracy of the new classification system and comparison between the new and the classic classification. This study aimed to compare the reliability and accuracy of the medial malleolar fracture classification based on 3D CT reconstruction and the Herscovici classification system. Methods We retrospectively analyzed the consecutive ankle fractures in our hospital from January 2013 to September 2020. Five inexperienced and five experienced orthopedic surgeons were included as observers to assess 68 cases with medial malleolar fractures. Ten evaluators classified the cases according to the two classification systems. The reference results of each case were made by the consensus of three senior trauma surgeons. The interobserver reliability, intraobserver reliability, and accuracy were evaluated at an interval of 6 weeks using Fleiss's kappa (κ) statistics. Results We found substantial interobserver and intraobserver reliability and 81.4% accuracy for the new classification, which was statistically superior to the Herscovici classification ( P < 0.05). The reliability and accuracy of both classifications were similar in inexperienced and experienced groups, except for type III in the new classification. The interobserver reliability of type II was the best ( P < 0.05), and the intraobserver reliability of IVc ranked the worst ( P < 0.05) in the new classification. Conclusion The reliability and accuracy of the new classification are superior to the Herscovici classification. Clinical experiences will not affect the assessment of both classification systems in most instances.
