Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Objective To propose a quick and low-cost personalized diabetic foot modeling and insole design scheme, so as to reduce the plantar pressure accurately. Methods The foot model of the patient was constructed by scaling the model with foot feature parameters, to make biomechanical analysis on plantar pressure. By means of numerical mapping model of insole elasticity and plantar pressure, the three-dimensional (3D) personalized insole model with gradient modulus was constructed. The insole was then manufactured via 3D printing technology and used for experimental validation. Results The related mechanical parameters from finite element prediction of the foot model constructed by the scaling modeling method were close to those of the CT reconstructed model, and the maximum error was controlled within 15%. Compared with wearing the normal insole, the peak pressure of the personalized insole was effectively reduced by 20%. The time and economic cost of this simplified design was reduced by approximately 90%. Conclusions The design scheme of the diabetes insole shortens the design cycle, and the personalized insole can effectively and accurately reduce the sole pressure, and reduce the risk of foot ulcer, which provides a technical basis for the promotion of the personalized diabetes insole.

Objective:To investigate the effect of early ambulation time on lower limbs muscle strength and fear of falling in patients with total knee arthroplasty, so as to provide basis for promoting the postoperative rehabilitation of patients undergoing total knee arthroplasty.Methods:A total of 210 patients after unilateral total knee replacement from July 2018 to December 2019 in the Second Affiliated Hospital of Soochow University were included and assigned to experimental group 1, experimental group 2 and experimental group 3 by random digits table method, each group contained 70 cases, and the patients began ambulation at 16, 20, 24 hours after knee replacement, respectively. The peak torque (PT) of knee joints flexors and extensor as well as hamstrings quadriceps ratio (H/Q) were compared among three groups at 1 week, 1 month and 3 months after knee replacement. The fall efficiency was evaluted by Modified Fall Efficacy Scale (MFES), the fear of falling rate was conducted by single item method.Results:After 1 month of knee replacement, the PT of knee joints flexor and extensor and H/Q were (18.73±5.49) N·m, (37.56±7.76) N·m, (48.08±9.19)% and (18.44±5.27) N·m, (37.04±7.07) N·m, (47.49±9.30)% in the experimental group 1 and experimental group 2, which were higher than those in the experimental group 3(16.38±2.85) N·m, (33.75±6.75) N·m, (43.48±7.17)%, the differences were statically significant ( t values were 2.316-3.057, P<0.05). After 1 week of knee replacement, the fear of falling rate were 72.3%(47/65) and MFES scores were (3.14±0.58) points in the experimental group 1, 53.7%(36/67), (3.81±0.65) points and 50.8%(32/63), (3.87±0.74) points in the experimental group 2 and experimental group 3, the fear of falling rate significantly increased and MFES scores significantly decreased in the experimental group 1 compared to the experimental group 2 and experimental group 3, the differences were statistically significant ( χ2 values were 5.780, 4.878, t values were 6.221, 6.129, P<0.05). Conclusions:Twenty hours after knee replacement is the best time for ambulation, which can shortern the time for lower limbs muscle strength recovery and reduce the risk of fear of falling.

Since December 2019, the corona virus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (2019-nCoV) has been reported in Wuhan, Hubei Province. Almost 70% of patients susceptible to 2019-nCoV are over age of 50 years, with extremely large proportion of critical illness and death of the elderly patients. Meanwhile, the elderly patients are at high risk of osteoporotic fractures especially osteoporotic vertebral compression fractures (OVCF). During the prevention and control of COVID-19 epidemic, orthopedists are confronted with the following difficulties including how to screen and protect OVCF patients, how to accurately diagnose and assess the condition of OVCF patients with suspected or confirmed COVID-19, and how to develop reasonable treatment plans and comprehensive protective measures in emergency and outpatient clinics. In order to standardize the diagnosis and treatment of patients with OVCF diagnosed with COVID-19, the authors jointly develop this expert consensus. The consensus systematically recommends the standardized emergency and outpatient screening and confirmation procedures for OVCF patients with suspected or confirmed COVID-19 and protective measures for emergency and outpatient clinics. Moreover, the consensus describes the grading and classification of OVCF patients diagnosed with COVID-19 according to the severity of illness and recommends different treatment plans and corresponding protective measures based on the different types and epidemic prevention and control requirements.

Transplantation is one of the clinical surgical methods to reconstruct and restore the function of the body. However, patients undergoing transplantation may develop various degrees of dysfunction and secondary physiological, psychological and social problems before and after operation. Transplantation rehabilitation based on enhanced recovery after surgery can improve the dysfunction and quality of life of patients. This paper introduced the conception of transplantation rehabilitation, and reviewed the application of transplantation rehabilitation in respiratory system, cardiovascular system, musculoskeletal system, cognition and nervous system, psychological and other aspects.

Mental stress may influence the autonomic nervous system (ANS) activity, and associate with the development of several chronic diseases. Mindfulness-based interventions, such as meditation, Yoga and Taiji Quan, are able to improve mental stress and ANS activity, which is probably related to its effects on the cortex to improve overall mental conditions and parasympathetic tone.
