Ninety percent of elderly patients with lumbar disc herniation (LDH) have problems with the mechanics of the spine and muscle tissue. Shi-style spine balance manipulation combined with guidance (Daoyin) of muscle and bone as an alternative therapy for LDH can tone the muscle groups around the spine and maintain optimal mechanical and static sagittal balance of the spine. This study will be performed to investigate the effect of a combination of Shi-style spine balance manipulation and Daoyin therapy on LDH in middle-aged and elderly patients. In this non-blinded, randomized controlled trial, 72 eligible patients will be randomly divided into a treatment group (Shi-style spine balance manipulation combined with Daoyin therapy) and a control group (lumbar mechanical traction). Before and after the intervention, lumbar X-ray and magnetic resonance imaging examinations will be performed to observe the sagittal balance parameters of the spine and pelvis and the lumbar muscle strength. The visual analog scale score, Oswestry disability index score, and pressure pain threshold will be evaluated at baseline and at 2, 4, 12, and 24 weeks. During the treatment period, any signs of acute adverse events, such as paralysis of the lower extremities or cauda equina syndrome, will be recorded at each visit. Although Shi-style spine manipulation combined with Daoyin therapy has been used in the treatment of LDH in middle-aged and elderly people in China for many years, there is no consensus on its effectiveness. This experiment will provide convincing evidence of the efficacy of Shi-style spine manipulation combined with Daoyin therapy in the treatment of LDH in middle-aged and elderly people.

This is a retrospective evaluated. The objective of this study was to test the interobserver reliability and intraobserver reproducibility of fracture classification with Arbeitsgemeinschaftfür Osteosynthesefragen (AO) system and Fernandez system used by 5 senior orthopedic surgeons. Anteroposterior and lateral radiographs of 160 patients hospitalized for displaced distal radius fracture were examined. Independently, 5 orthopedic surgeons evaluated the radiographs according to 2 different distal radius classification systems (3 types of results). Three statistical tools were used to measure interobserver reliability and intraobserver reproducibility. The intraclass correlation coefficient and kappa coefficient (k) were used to assess both interobserver and intraobserver agreement of AO and Fernandez. Kappa value indicated poor agreement (

Background: Cervical spondylotic myelopathy (CSM) is the most serious type of cervical spondylosis, which is often treated surgically in patients with progressive neurological symptoms following ineffective conservative treatment. However, some patients have residual symptoms such as neck pain, stiffness, and C5 nerve palsy after surgery. The Qishe pill can effectively relieve the symptoms of neck pain and numbness, but there is no evidence showing the efficacy and safety of the Qishe pill in treating symptoms after spinal cord surgery. Methods/design: A multicenter, randomized controlled clinical trial will be conducted to evaluate the efficacy and safety of the Qishe Pill. A total of 330 patients with CSM who receive surgical treatment will be randomly divided into 2 groups, treated for 12 weeks and with a 1-year follow-up. The primary outcome will be Japanese Orthopaedic Association score from the baseline to 4 weeks, 12 weeks, 24 weeks, and 48 weeks after surgery. Secondary outcomes will include Visual Analogue Scale score, Neck Disability Index, and imaging indicators (including magnetic resonance imaging and X-ray). Additionally, adverse reactions will be observed and recorded as safety indicators. Discussion: Although the Qishe pill can effectively improve the discomfort of the neck and upper limbs in clinical applications, there is a lack of clinical research on postoperative patients. This study will investigate the efficacy and safety of the Qishe pill in treating postoperative symptoms of CSM. Trial registration: Clinical Trials.gov ID: ChiCTR1900028173.

Objective To assess the efficacy of extracorporeal shockwave therapy (ESWT) and provide clinicians with an evidence base for their clinical decision making. Data Sources PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Evidence-Based Medicine Reviews. Study Selection All randomized or quasi-randomized controlled trials of ESWT for chronic recalcitrant plantar fasciitis were searched. Searching identified 108 potentially relevant articles; of these, 7 studies with 550 participants met inclusion criteria. Data Extraction Number of patients, population, body mass index, duration of symptoms, adverse effects, blinding method, and details of shockwave therapy were extracted. Data Synthesis For intervention success rate, ESWT of low intensity was more effective than control treatment of low intensity. For pain relief, the pooled data showed a significant difference between the ESWT and control groups. For function, only low-intensity ESWT was significantly superior over the control treatment. Conclusions The efficacy of low-intensity ESWT is worthy of recognition. The short-term pain relief and functional outcomes of this treatment are satisfactory. However, owing to the lack of a long-term follow-up, its long-term efficacy remains unknown.

In china, with the development of GPS, GIS, RS, 3S technology is gradually used in the agriculture in recent years. This paper introduced the concepts of GPS, GIS, RS. Considering the fact of the Chinese agriculture, we developed the farmland information support system based on the integration of GPS, GIS, RS. With the application of this system in some counties of Yunnan province, the work mode of the department of the agriculture has started to be changed.

Based on SRTM DEM data, Arc Hydro Tools of ArcGIS is firstly employed with Red River as an example in this paper. On the basis of D8 algorithm, the authors then confirm flow direction of raster units according to the steepest gradient as well as starting-point and end-point of river section by means of threshold catchments area. Next, searching for upstream water-supply district of each river section from sub-watershed exit, the boundaries of whole watershed and each sub-watershed are obtained, which will finish characteristics extracting and generate digital Red River watershed. Eventually, experiment result of watershed is analyzed.

With the development of the project of Formula Fertilization by Soil Testing in china,in order to investigate the soil condition,fertility level,nutrients status,soil degeneration status and the farmland integrated productivity of china,the government decided to start up the project of the Evaluation of the farmland productivity with the field investigation data and the analysis assay data, which were got in the project of Formula Fertilization by Soil Testing. Based on the spatial analysis function of the geographic information system(GIS), such as overlay analysis and spatial interpolation,using soil image,Present land use map and administrative map of the poroject area?this research decided evaluation unit and connected the field investigation data and the analysis assay data. Considering the actual conditions of the poroject area, the experts selected Sixteen affected factors from four aspects as land management?land growing situation?profile situation and soil nutrient content?and the evaluation system of farmland fertility of was built up?Aimed at the affected factors,It adopts the Delphi method to identify the membership function of severa1 affected factors and introduces Analytica1 Hierarch process (AHP) to calculate the weight of evaluating factors.On the basis of these datas,this research used the Additive Model to calculate the Integrated Fertility Index(IFI) and also analyses its space distribution?Because The results are in 1ine with the local situation of the city,This result can be applied to agricultural production.

Parallel editing of spatial data is one of the concern focuses in GIS research. The paper firstly discusses current status of research and analyzes mechanism and implement method of ArcSDE version management. With ArcObjects component as exploitation platform and Visual Basic as tools, a version management component is designed and developed and integrated into application software which implements multi-users parallel editing and version management of spatial data.
