ObjectiveTo summarize the evolving concept in treatment of intertrochanteric fractures and the development of internal fixation devices. MethodsRelated literature concerning the implant devices to treat intertrochanteric fractures was reviewed and analyzed in terms of the biomechanical characteristics, clinical application, and complications. ResultsThe treatment of intertrochanteric fractures has undergone an evolving concept from conservative treatment to surgical treatment. Surgery strategies include extramedullary fixation and intramedullary fixation. Intramedullary fixation has gradually become the main treatment of intertrochanteric fractures due to its minimally invasive and biomechanical advantages. However, the current intramedullary fixation system still can not reconstruct the medial cortical support of the proximal femur, which leads to some failures in the treatment of unstable fractures. ConclusionThe development of internal fixation of intertrochanteric fractures is based on the deep understanding and biomechanical theory of intertrochanteric fractures in clinical practice. In the future, the updated design of internal fixation devices will depend on the treatment principle of reconstruction of medial support and secondary stabilization of intertrochanteric fractures, and finally the purpose of improving success rate and reducing postoperative complications of intertrochanteric fracture will achieved.
ObjectiveTo explore the effect of a new rehabilitation intervention model based on International Classification of Functioning, Disability and Healthy (ICF) concept in perioperative treatment on patients with adolescent idiopathic scoliosis (AIS).MethodsFrom June 2017 to January 2019, AIS patients with Cobb angle below 80° were randomly divided into experimental group and control group by the method of randomized block design. The patients in the control group received routine perioperative rehabilitation intervention, while the patients in the experimental group received rehabilitation mode intervention based on ICF concept. The therapeutic effect of the two groups including functional and activity dimensions was observed.ResultsA total of 40 patients were included, with 20 in each group. Two patients withdrew the control group. On the fourth day after surgery, the total score of Modified Barthel Index (50.55±8.87 vs. 18.99±5.63; t=13.264, P<0.001) and Scoliosis Research Society-22 (SRS-22) (3.68±0.13 vs. 3.27±0.11; t=10.355, P<0.001) in the experimental group were all better than those in the control group. In the SRS-22 scores, statistically significant differences in comparison of function (2.79±0.29 vs. 1.90±0.48; t=6.884, P<0.001), and self image (3.91±0.27 vs. 3.38±0.32; t=5.539, P<0.001) between the two groups were found. There was no statistically significant difference in pain indicators and muscle strength between the two groups in the two postoperative evaluations (P>0.05). ConclusionsThe treatment based on the concept of ICF can improve the daily living ability in the short term with the safe and acceptable premise. The concept of stimulating patient autonomy, improving patient independence, and promoting social treatment, may improve the overall state of the patients.

Ilizarov’s technology is an internationally recognized clinical treatment method for limb orthopedics, but there are many complications related to external fixation. With the development and progress of the times, the remote-control intramedullary lengthening nails had risen to prominence on the international stage as the second generation of orthomelic technology based on Ilizarov’s technology. Since the first remote-control intramedullary lengthening nail appeared in the 1980s, after more than 40 years of development, there are currently more than 3 types of extension mechanisms in remote-control intramedullary lengthening nails and a mature and stable clinical treatment model has been formed during the past long-term clinical treatment and experiments, such as the End-Point-First (EPF) program proposed by Professor Peter H. Thaller in Germany. Compared with Ilizarov’s technology, the remote-control intramedullary lengthening nail has obvious advantages in convenience, comfort, risk of infection, soft tissue injury, postoperative pain, and controllability of limb lengthening. This article mainly introduces the development and clinical treatment concept of remote-control intramedullary lengthening nail and the latest clinical treatment status of limb lengthening therapy abroad, hoping to provide new cognition and ideas for the further development of limb orthopedics in China.
ObjectiveTo investigate the effectiveness of the treatment under the guidance of “diamond concept” for femoral shaft fractures nonunion after intramedullary fixation.MethodsBetween January 2014 and December 2016, 21 cases of femoral shaft fractures nonunion after intramedullary fixation were treated with auxiliary plate fixation combined with autogenous iliac graft, and autologous bone marrow concentrate and platelet-rich plasma (PRP) gel under the guidance of the “diamond concept”. There were 13 males and 8 females, with an average age of 32.5 years (range, 17-48 years). All fractures were closed femoral shaft fractures. Four patients underwent internal fixation with plate and resulted in nonunion, then they were fixed with intramedullary nails, but did not heal either. The rest 17 patients were fixed with intramedullary nailing. Fracture nonunion classification: 4 cases of hypertrophic nonunion, 17 cases of atrophic nonunion; the length of bone defect was 1-3 mm; the duration from the last treatment to the current treatment was 10-23 months (mean, 14.3 months). The operation time, intraoperative blood loss, the time between operation and full loading, fracture healing time, and complications were recorded. The visual analogue scale (VAS) score and the imaging system of fracture healing of the extremities (RUST) of patients before operation and at last follow-up were recorded to evaluate the fracture healing; the function of the affected limb was evaluated according to the Schatzker-Lambert efficacy score standard at last follow-up.ResultsThe operation time was 105-160 minutes, with an average of 125.6 minutes; the intraoperative blood loss was 160-580 mL, with an average of 370.5 mL. All incisions healed by first intention, without vascular or nerve injury. All patients were followed up 22-46 months (mean, 26.5 months). All the fractures healed, with a fracture healing time of 3-7 months (mean, 4.8 months). During the follow-up, there was no infection, loosening, implant breakage, re-fracture, and other complications. The VAS score at last follow-up was 0.8±0.3, showing significant difference (t=7.235, P=0.000) when compared with preoperative score (5.2±3.7); the RUST score was 3.4±0.3, which was significantly higher than the preoperative score (1.5±0.7) (t=8.336, P=0.000). According to the Schatzker-Lambert effectiveness evaluation standard, the limb function was excellent in 16 cases, good in 4 cases, fair in 1 case, and the excellent and good rate was 95.42%.ConclusionNonunion after intramedullary fixation of femoral fracture treated with auxiliary plate combined with autogenous iliac graft, autogenous bone marrow concentration and PRP gel in accordance with the “diamond concept” can not only restore the stability of the fracture ends, but also improves the biological environment of the fracture site, and can improve the rate of fracture healing.

Acute pancreatitis is a common surgical acute abdomen in clinical practice. With the development of minimally invasive technology, more and more treatment methods are being applied to acute pancreatitis, especially for severe acute pancreatitis and acute biliary pancreatitis. At present, the efficacy of integrated traditional Chinese and Western medicine in the treatment of acute pancreatitis has been widely recognized. In terms of minimally invasive diagnosis and treatment of acute pancreatitis, the “SELECT” concept of integrated traditional Chinese and Western medicine minimally invasive diagnosis and treatment has emerged. Based on the severity and etiology of acute pancreatitis, the optimal combination of multiple endoscope (Spyglass, encoscopic retrograde cholangiopancreatography, laparoscopy, endoscopic ultrasound, choledochoscopy) is selected, and combined with traditional Chinese medicine treatment. With a patient-centered approach, we have achieved minimally invasive, individualized, and precise treatment of acute pancreatitis through the integration of traditional Chinese and Western medicine.

Objective To summarize the optimal evidence for improving the management of chronic wounds exudate, so as to provide evidence-based references for medical professionals, therapists, patients, and their caregivers. Methods PubMed, Wanfang, CNKI, Medlive, UpToDate, etc., were searched by computer for literature about chronic trauma exudate management. The retrieval time limit was from 1998 to 2023. Two researchers trained in evidence-based practice evaluated the quality of the included literature and finally extracted evidence from the literature that met the quality evaluation criteria. Results A total of 11 articles were included, including 2 expert consensuses, 7 systematic reviews, 1 randomized controlled trial, and 1 guideline, covering 7 aspects of the assessment of the nature of chronic wounds exudate, selection of exudate assessment tools, management of antimicrobial concerns, selection and application of wound dressings, negative pressure wound drainage therapy, wound drainage bags, and affected limb elevation or compression therapy for patients with venous leg ulcers. A total of 13 best evidences were extracted. Conclusions When applying evidence, medical professionals should fully evaluate and combine the individual circumstances of the patient, make full use of existing resources, new treatment concepts and technologies, and carry out comprehensive integrated management. This can optimize the management of chronic wounds exudate and improve the quality of life of patients.
To increase efficiency of automated leucocyte pattern recognition using lower feature dimensions, a novel inter-class distinctive feature selection method for chromatic leucocyte images was proposed based on attribute hierarchical relationship. According to the attribute constraints in formal concept analysis, we established a knowledge representation and discovery method based on the hierarchical optimal diagram by defining attribute value and visual representation of optimized hierarchical relationship. It was applied to human peripheral blood leucocytes classification and 12 distinctive attributes were simplified from 60 inter-class attributes, which contributes significantly to reduced feature dimensions and efficient inter-class feature classification. Compared with the classical experimental data, the inter-class distinctive feature selection method based on hierarchical optimal diagram was proved to be usable and effective for six leucocyte pattern recognition.
