ObjectiveTo observe the temporary loss (re-falling) of knee range of motion (ROM) during rehabilitation after arthrolysis for post-traumatic knee stiffness, and analyze the factors related to it. MethodsFrom July, 2016 to September, 2019, 64 patients (68 knees) in Beijing Bo'ai Hospital accepted minimally invasive arthrolysis for post-traumatic knee stiffness, and were followed up for twelve months. ROM of flexion and extension of knee was measured before operation, and one, six and twelve weeks, and six and twelve months after operation; while they were asssessed with Hospital for Special Surgery Knee Score (HSS). Multivariate Logistic regression was performed on re-falling. ResultsThe ROM and HSS score improved as a whole after operation; however, HSS score improved constantly, but ROM decreased six weeks after operation compared with that one weeks after operation, involving 46 knees of 44 cases. Arthrolysis longer than 12 months from primary injuries, multiple complicated fracture and history of infection were the risk factors for re-falling (OR > 8.058, P < 0.05). ConclusionMinimally invasive arthrolysis is effective on knee function after arthrolysis for post-traumatic knee stiffness. However, re-falling of ROM may happen during rehabilitation. Delay of operation, multiple complicated fracture and history of infection may increase the risk of re-falling.
Résumé
Comprehensively improving the new efficiency of high-quality development of public hospitals is the key top-level design for deepening the reform of public hospitals during the"14th Five-Year Plan"period.In view of the changes in the macro environment faced by public hospitals in recent years,such as the cancellation of the addi-tion of pharmaceutical consumables and the deep promotion of the reform of payment methods,as well as the out-standing problems existing at the micro level of public hospital operation,such as the separation of diagnosis and treatment business from economic operation activities,extensive decision-making methods,unreasonable alloca-tion of resources and urgent optimization of processes.By referring to relevant theories such as value management theory,a new"trinity"public hospital lean operation management model based on"integration of industry and fi-nance,lean operation and evidence-based decision-making"is explored and constructed.It breaks the relatively parallel operation barriers of clinical diagnosis and treatment business and economic operation management,innovates a new method of linear staff management with the integration of industry and finance,gives full play to the role of experts in governing hospitals,and integrates the professional committee system driven by"technology+manage-men"into the hospital decision-making staff system to provide data evidence-based basis for assisting the hospital leadership to make scientific decisions.
Résumé
The establishment of an economic operating mechanisms for hospitals is a key factor in advancing the growth of public hospitals in the modern age.At present,the due value of key factors such as medical resources and labor value of medical personnel in public hospitals in China has not been fully reflected,which not only restricts the overall operation efficiency of hospitals,but also makes it difficult to realize the marginal value of hospital operation and management.The economic operating mechanisms of public hospitals is in urgent need of reform.Large public hospitals in Henan Province has established an economic operating mechanisms of public hospitals based on intelli-gent finance,comprehensive budget management as the core,and cost control and performance management as the major tools to realize the interconnection of various systems and promote the high-quality development of hospi-tals with the three major supports of industry and finance integration,financial integration and financial integration.

Objective:To analyze the factors influencing dysphagia after an injury to the cervical spinal cord (CPCI) to provide a basis for clinical screening and intervention.Methods:A total of 110 CPCI patients with dysphagia were divided into a severe dysphagia group ( n=19), a mild dysphagia group ( n=35), and a control group ( n=56) according to their functional oral intake scale scores. Data on gender, age, level of injury, degree of damage, duration of injury, causes of injury, surgical mode, tracheotomy status, occurrence of pneumonia and pharynx swelling were collected. Univariate and multivariate logistic regressions were evaluated to identify factors affecting swallowing. Results:The regressions highlighted age, the severity of the spinal cord injury, tracheotomy status, and the occurrence of pneumonia and pharyngeal swelling during hospitalization as the best predictors of swallowing difficulties. Multifactoral logistic regression analysis revealed that undergoing tracheotomy and catching pneumonia during hospitalization were major risk factors for severe dysphagia.Conclusions:Tracheotomy and pneumonia during hospitalization are useful predictors of severe dysphagia after a cervical spinal cord injury.
Résumé
Nicotinamide mononucleotide (NMN) is an important precursor in conversing nicotinamide adenine dinucleotide (NAD +) in the body. By elevating NAD + level in the body, NMN enhances the hydrogen transfer function of NAD + in biological processes, promotes the synthesis of proteins and polysaccharides, improves substance transportation and regulatory efficiency, and enhances metabolic functions. Specifically, in central nervous system disease, NMN exerts neuroprotective effect through antioxidation, anti-inflammation, mitochondrial protection, and prevention of neuronal and axonal degeneration. This review focuses on the therapeutic role of NMN in common central nervous system diseases and their neuroprotective mechanisms, so as to further understand the role of NMN in central nervous system diseases, and provide references for predicting therapeutic targets and screening therapeutic drugs for central nervous system diseases.
Résumé
Liver stiffness measurement (LSM) has been widely used in predicting portal hypertension in clinical practice, and in recent years, spleen stiffness measurement (SSM) has also become a diagnostic tool. Studies have shown that SSM can predict portal hypertension and its complications such as esophagogastric variceal bleeding in patients with chronic liver diseases and assist in the risk stratification management of portal hypertension and esophagogastric variceal bleeding. It can accurately predict clinically significant portal hypertension, high-risk esophageal and gastric varices, decompensation rate, and mortality rate in patients with chronic liver diseases. At present, SSM data in most studies are obtained by detection using the liver equipment FibroScan Ⓡ (SSM@50 Hz). FibroScan Ⓡ 630 is a new scanner dedicated for SSM with a special mode for SSM (SSM@100 Hz). This article elaborates on the significance of SSM in predicting portal hypertension and briefly introduces the advantages and disadvantages of the new equipment for SSM.
Résumé
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.
Résumé
Dyslipidemia is an important risk factor of atherosclerotic cardiovascular disease (ASCVD). Statins delay the occurrence and development of ASCVD, and reduce the risk of cardiovascular events and death. Due to safety concerns, there exist insufficient use of lipid-lowering agents and a high withdrawal rate of the agents in the elderly. To promote the prevention and treatment of ASCVD, this expert consensus is issued and focuses on the management of dyslipidemia of Chinese elderly basing on the clinical evidence of the use of lipid-lowering drugs by the elderly, and the lipid management guidelines and expert consensus recommendations at home and abroad.
Résumé
The clinical, imaging, genetic, therapeutic and prognostic features of a case of pediatric stroke who was finally diagnosed with Aicardi-Goutières syndrome (AGS) in Xi′an International Medical Center Hospital on October 24, 2021 were reported. A 10-year-old boy was admitted to the hospital due to weakness of the right limb for more than 10 hours. The pre-hospital CT showed multiple patchy calcifications in the bilateral frontal lobe and the right parietal lobe cortex-medullary junction. The physical examination on admission had chilblains on the hands, feet and face. National Institutes of Health Stroke Scale Score was 4 points. Brain magnetic resonance imaging showed acute brainstem infarction, no abnormality in magnetic resonance angiography, ultrasound and electrocardiogram of heart and neck vessels were normal, cerebrospinal fluid biochemistry and routine examination were normal, blood routine, biochemistry, coagulation, autoantibody series, thyroid function, tumor markers, human immunodeficiency virus and syphilis examinations were normal. After oral administration of aspirin anti-platelet aggregation and rehabilitation exercises, the muscle strength returned to normal and the patient was discharged. One month later, the result of genetic testing was reported as AGS caused by TREX1 gene mutation, and the mutation site is c.58G>A. AGS is a rare autoimmune hereditary encephalopathy with a large heterogeneity of clinical manifestations. When a hereditary disease was suspected, genetic testing should be done.
Résumé
ObjectiveTo evaluate the overall demand for rehabilitation services from the perspective of the groups with disabilities, diseases, injuries and older adults, and explore the causes of the supply and demand gap of rehabilitation services. MethodsThe literatures in the field of rehabilitation were collected, summarized and analyzed, including policy documents issued by World Health Organization and relevant departments in China, surveys, and researches. ResultsThe demand for rehabilitation services caused by disabilities, chronic diseases, injuries and population ageing were vast in China, but many were still unmet. The main reasons leading to the gap included those population trend and health situation, the insufficient reserve of rehabilitation resources coming from incomplete development of rehabilitation service system early, and inadequate construction of disability reporting system, which could not efficiently meet rehabilitation demand with supply. ConclusionThe strategies to optimize the rehabilitation services system and promote the quality of the services based on the disability reporting system are warranted.
Résumé
For cochlear implant training and robotic cochlear implant experiments, the design method of scalable scala tympani model was proposed. The mathematical model of the cochlea was used as the central curve of scala tympani channel. Referring to the clinical anatomy data, the contour of the scala tympani cross-section was approximated as an ellipse. The profile was placed along the central curve, and the angle was adjusted to determine the position and orientation of the profile in three dimensions such that the central curve passes through its center. The data was imported into Matlab to generate a three-dimensional mathematical model of scala tympani, which can be expanded by setting different scale factors. The virtual scala tympani model was generated in SolidWorks, and the 2:1 fully transparent scala tympani model were fabricated by 3D printing to replace the specimen for experiment.

Objective:To seek better treatments for abnormal pelvic floor muscle tension and pelvic floor dysfunction after spinal cord injury.Methods:The morphology of pelvic floor muscle fibers of rats with spinal cord injury at different levels was observed under the electron microscope. Thirty female adult Sprague-Dawley rats were randomly divided into a suprasacral (SS) cord injury group, a group with spinal cord injury at or below the sacral level (SC) and a normal group (NG), each of 10. The relevant spinal cord injury models were established in the SS and SC groups through spinal cord disconnection. Four weeks later, the pixel area of ATPase-positive fibers was used to quantify the content of type I fibers in the pubococcygeus muscle of each rat through observation under the electron microscope after hematoxylin and eosin staining.Results:The average content of type I muscle fibers in both the SS and SC group was significantly lower than in the normal group. The SC group′s average level was significantly lower than that of the SS group. Under the microscope the stained myofibers were tortuous, deformed in appearance and with proliferated nuclei. Capillary dilation could be seen locally in the SS group 4 weeks after the injury. In the SC group at 4 weeks after the injury the pubococcal fibers were seriously "dissolved" , or disordered, with spherical nuclei and mild hyperplasia. Under the electron microscope, the sarcomeres of the SC group were obviously dissolved, atrophied and broken, though the basic structure persisted, with mild mitochondrial proliferation. The sarcomeres of the SC group were extremely dissolved and broken, completely losing basic structure, with abundant connective tissue proliferation but without obvious mitochondrial proliferation.Conclusions:After suprasacral cord injury, the content of type I muscle fibers in the pubococcygeus muscle of the pelvic floor decreases somewhat, with the basic structure of the muscle fibers remaining intact. However, after spinal cord injury at or below the sacral level, type I muscle fibers decrease significantly in the pubococcygeus muscle of the pelvic floor, and the basic structure is seriously damaged.

Objective:To analyze the clinical data on hospitalized spinal cord injury patients with calf muscle vein thromboses (MCVTs) seeking prevention and treatment techniques.Methods:The medical records of 423 patients with spinal cord injury were collected. Those with MCVT constituted the observation group, while those without served as controls. Their clinical data were compared.Results:The risk factors for MCVT were screened in logistic regression analyses. The results showed that age, an ASIA grade of A or B, spinal fusion, preventive anticoagulation, physiotherapy treatment and a homocysteine level >15μmol/L were risk factors for the occurrence of a MCVT.Conclusions:Age, an ASIA grade of A or B, spinal fusion or an elevated serum homocysteine level are all risk factors for MCVT. Active anticoagulation and physical therapy may reduce the risk.

Objective:To investigate the characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection (ESD) for early esophageal carcinoma.Methods:Patients who underwent ESD in the Digestive Endoscopy Center of the Second Affiliated Hospital of Army Medical University from January 2011 to December 2018 were included. The data were obtained from medical records and follow-up. The influencing factors of stenosis were determined by single factor and Cox regression analysis.Results:A total of 654 patients underwent ESD and 79 (12.1%) of them developed postoperative esophageal stenosis. The median time of stenosis development was 27 (17, 43) days. The morphology and lesion circumferential proportion were independent factors for the occurrence of stenosis after ESD. The stenosis incidence of type Ⅱa was 6.601 times (95% CI: 1.518-28.709, P=0.012) compared with that of type Ⅱc. The incidence of stenosis in lesions with 75%-<100% and 100% circumference was 17.408 times (95% CI: 8.009-37.839, P<0.001)and 52.439 times (95% CI: 23.905-115.029, P<0.001) respectively compared with that of patients <75%. Among the 79 patients, 27 had severe stenosis, and the lesion circumferential proportion was an independent factor for stenosis. Compared with the group of lesion circumferential proportion of less than 75%, the incidences of stenosis of lesion circumferential proportion of 75%-<100% and 100% were 7.775 (95% CI: 1.977-30.577, P=0.003) and 70.062 (95% CI: 19.879-246.926, P<0.001) times respectively. Conclusion:The morphology and lesion circumferential proportion are two independent factors for the occurrence of esophageal stenosis after ESD. Additionally, lesion circumferential proportion is an independent factor for the occurrence of severe esophageal stenosis after ESD.
Résumé
Time-driven activity based costing is embraced in the healthcare sector for its correction of inherent defects of activity-based accounting. The authors constructed a two-level hierarchical cost accounting model for medical service items based on the time-driven ABC. The first-level hierarchical cost is calculated down to the department level in line with cost management regulations of the hospital financial system, while the second-level cost allocation is based on " time" as the basic sharing criterion, which is collected and assigned to specific medical service items with the activity content and process as carriers. The standard cost and actual cost of comparable medical service projects are calculated respectively by means of introducing the concept of socially necessary labor-time, which provides a scientific and feasible management method for evaluating the performance of medical service items.

OBJECTIVE@#To investigate the effect of bilateral superior cervical sympathetic ganglion occlusion (SCG) on aortic dissection and its possible mechanism.@*METHODS@#Forty-five SD rats were randomly divided into three groups with 15 in each:blank control group, sham operation group and SCG group. β-aminopropione (666 mg·kg·d) was given by subcutaneous injection for 4 weeks to establish the aortic dissection model. Rats in SCG group were given SCG before the injection of β-aminopropione. Blood pressure and heart rate of the rats were monitored using noninvasive tail artery blood pressure measuring instrument; sympathetic activity was monitored using drug block method; the structure of aortic wall was observed using HE staining; collagen fibers in aortic wall was observed using Sirius red staining; protein expression of Apelin was detected by immunohistochemistry; and the protein expression of matrix metalloproteinase (MMP)-2, 9 was detected by Western blotting.@*RESULTS@#During the experiment, the body mass of the sham operation group and SCG group was smaller than that of the blank control group (all <0.05), and the body mass of the SCG group was larger than that of the sham operation group (all <0.05). The heart rate and sympathetic activity of the sham operation group were higher than those of the blank control group (all <0.05), while the SCG group were lower (all <0.05). Compared with the blank control group, the aortic wall in the sham operation group was thickening, while that in the SCG group was improved. A large number of collagen-1 in the aortic wall of the blank control group was stained brown by Sirius red, which was lighter in SCG group, and the staining in the sham operation group was the lightest. Compared with the blank control group, the expression of Apelin, MMP-2 and MMP-9 protein in the sham operation group increased (all <0.05), while those in the SCG group decreased (all <0.05).@*CONCLUSIONS@#SCG can effectively reduce the incidence and mortality of aortic dissection in rats, which may be related to the inhibition of sympathetic activity and the decrease of collagen-1, Apelin, MMP-2 and MMP-9 expression.

Objective: To understand the characteristics of HIV infected persons without long term disease progress [also known as long term non-progressors (LTNPs)], and related factors in Guangxi Zhuang Autonomous Region (Guangxi). Methods: Data of persons living with HIV and receiving no antiretroviral therapy in Guangxi by the end of 2016 were collected from the national HIV/AIDS comprehensive control and prevention information system of China. Results: By the end of 2016, there were 313 LTNPs in Guangxi, accounting for 2.3% of those being reported for more than 10 years, 5.4% of those being reported for more than 10 years and surviving, and 26.6% of those being reported for more than 10 years, surviving and receiving no antiretroviral therapy. Among the LTNPs, 87.2%(273) were men, 94.9% (297) were aged ≤ 40 years, 32.3% (101) were farmers, 55.6% (174) were single, divorced or widowed, 69.3% (217) were of Han ethnic group, 68.1% (213) were injecting drug users, and 52.1% (163) were from custody facilities. Multiple logistic regression analysis indicated that factors associated with delayed disease progression included age ≤40 years (compared with age >40 years, aOR=1.55, 95%CI: 1.31-3.12) and injection drug use (compared with sexual transmission, aOR=1.23, 95%CI: 1.10-1.74). Conclusions: A number of LTNPs existed in HIV-infected individuals in Guangxi. Further research are needed to identify the related factors, and it is necessary to conduct large sample size studies on host immunology, genetics and the virology of HIV to explore the related mechanism.
