ABSTRACT

Gait adaptability refers to adjustments of gait to accomplish walking and to overcome environmental difficulties. According to the training environment, gait adaptability training in stroke rehabilitation can be divided into two categories: real environment and simulated environment. The simulated environment is divided into simple indoor and multimoding environment. Some technologies, such as virtual reality and augmented reality may provide safer and more efficient methods for gait adaptability training. Gait adaptability training can improve walking function and confidence of hemiplegic patients, and help them to return to community life and social participation.

ABSTRACT

Objective:To compare the short-term effects of hip muscles strengthening and quadriceps strengthening on knee osteoarthritis (KOA), and discuss the advantages of hip muscles strengthening. Methods:From October, 2015 to May, 2016, 42 old females with KOA were divided into two groups equally. They received hip strengthening (HS group) and quadriceps strengthening (QS group) for two weeks, respectively. The pain, stiffness and physical function scores of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were measured. Isokinetic strength peak torque (PT) was assessed for knee extensors and flexors, and 6-minute Walk Test was also evaluated. They were followed up two months later. Results:Before exercise, there was no significant difference in all the indexes between two groups (P > 0.05). Two weeks after exercise, the knee flexor PT (t = -4.038, P = 0.001) and 6-minute walk distance (t = -2.474, P = 0.022) increased in QS group; the pain, stiffness and physical function scores of WOMAC (t > 2.487, P < 0.05), the knee extensor and flexor PT (|t| > 6.370, P < 0.001), and 6-minute walk distance (t = -2.241, P = 0.037) improved in HS group; the scores of WOMAC were lower (t > 2.087, P < 0.05) and the knee extensor PT was higher (t = -5.028, P < 0.001) in HS group than in QS group. At two-months' follow-up, the drop-out rate was significantly lower in HS group than in QS group (χ2 = 13.480, P < 0.001). Conclusion:Hip muscles strengthening is a good choice for KOA in the early stage of treatment, which could avoid the pain in quadriceps training, increase quadriceps strength and improve physical function.

ABSTRACT

Objective:To summarize our institutional experiences of screening and selecting potential recipients and living donors for uterine transplantation at a single center.Methods:A total of 102 patients were diagnosed as absolute uterine factor infertility (AUFI). Depending upon the outcomes of previous trials, 8 modules were selected for surveying. A registration form was distributed for subjects at outpatient clinics or through telephone consultations for clinical trials of uterus transplantation between November 2018 and October 2019. The relevant information was collected and entered into a dedicated system for data processing.Results:The number of eligible subjects was 84 and the number of recipients with potential donors 37. The average age of potential recipients was 26.0(18-47) years. Among potential recipients, 76(90.5%) had congenital AUFI and 8(9.5%) acquired AUFI. For potential donors with available organs, the average age was 47.5(32-64) years and the proportion of menopausal or peri-menopausal status 56.8%.Conclusions:Currently large demands and sufficient supports for conducting clinical trials of uterine transplantation are available in China. However, inherent deficiencies persist in organ donor population reserves and preoperative screening protocols, such as donor age and subjective/objective factors of participants. During clinical trials of uterine transplantation, preoperative screening should be performed for expanding the screening scope, extending the screening time and popularizing the screening knowledge to boost the success rate.

From June 2017 to December 2019, 1256 eyes of 628 premature infants who were born in Ningbo Women and Children's Hospital and were screened for ROP were included in the study. Among them, there were in 325 males (650 eyes) and 303 females (606 eyes). According to the feeding situation, premature infants were divided into breastfeeding (research) group and formula feeding (control) group, with 390 cases of 780 eyes and 238 cases of 476 eyes, respectively. The changes in the retina of the fundus of the two groups of premature infants during the observation period were compared. The qualitative data comparison between groups was performed by the χ2 test; the quantitative data comparison was performed by the two independent sample t test. Results:The sex ratio of premature infants in the study group and control group ( χ2=0.217), birth weight ( t=0.728), gestational age at birth ( t=0.351), Apgar score at birth ( t=0.816), oxygen inhalation time ( t=0.427), were compared with the length of stay in the neonatal intensive care unit ( t=1.580), the difference was not statistically significant ( P>0.05). Among the 390 cases in the study group, 108 cases (27.7%, 108/390) and 282 cases (72.3%, 282/390) were with or without ROP, respectively; in the 238 cases in the control group, 86 (36.1%, 86/238) were with ROP, 152 (63.9%, 152/238) cases were without ROP. There was a statistically significant difference in the incidence of ROP between the two groups ( χ2=4.934, P=0.026). Among the 108 cases of ROP in the study group, 50 (12.8%, 50/108), 35 (9.0%, 35/108), 23 (5.9%, 23/108) cases were in stage 1, 2 and 3, respectively. Among the 86 ROP cases in the control group, stages 1, 2 and 3 were 25 (10.5%, 25/86), 40 (16.8%, 40/86), and 21 (8.8%, 21/86), respectively. In the comparison of ROP staging between the two groups, the difference in stage 1 was not statistically significant ( χ2=0.754, P>0.05), and the difference in stage 2 and above was statistically significant ( χ2=11.400, P<0.05).

ABSTRACT

Objective:To explore systematic implementation of World Health Organization Family International Classifications (WHO-FICs) in the field of rehabilitation: the theoretical and policy framework at macro level, governance and management mechanism at meso level, and implementation modules at micro levels, respectively. Methods:The policy and theoretical framework of rehabilitation development was discussed based on the international rehabilitation policy documents of WHO, mainly as World Report on Disability, Global Action Plan on Disability and Rehabilitation in Health Service System. Protocol and roadmap of systematic implementation of WHO-FICs, including International Classification of Diseases (ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHIβ-2) was proposed. Results:With the use of WHO-FICs, the theoretical and policy framework of rehabilitation was constructed, and the contents and principles of modern rehabilitation services were clarified at macro-level. Rehabilitation is an important part of health service, there are six building blocks: i.e. leadership and governance, financing, human resources for health, service providing, medical technology and health information system. It proposed to use knowledge management system of WHO-FICs, including the classification, nomenclature, definitions, descriptions, terminology and coding systems, to standardize rehabilitation evaluation and statistics. The management and governance system of rehabilitation should be implemented using WHO-FICs. Rehabilitation services are based on the bio-psycho-social model and implemented the principles of people-centered and functioning-oriented. The systematic implementation of WHO-FICs in rehabilitation abide by the model of "Evaluation (ICHI)-Evaluation, Description, Classification and Coding of Functioning (ICF)-Disease Classification, Diagnosis and Coding (ICD)-Rehabilitation Intervention (ICHI)", and with the standardized process of "Evaluation (Functioning and unmet needs)-Diagnose (Disease and Functioning)-Planning of Rehabilitation-Intervention-Evaluation of Outcome". The mic-modules of implementation of WHO-FICs in rehabilitation had been constructed. There were 28 categories of diseases, 7 categories of functioning and 6 categories of rehabilitation interventions in rehabilitation proposed by International Society of Physical and Rehabilitation Medicine. According to ICD-11 and ICF, it proposed to use WHO Disability Assessment Schedule 2.0 (WHODAS 2.0), Brief Model Disability Survey (MDS-B) and VB40 Generic Functioning Domains (VB40), and the ICF core-sets in evaluation of functioning and rehabilitation outcome. The implementation of WHO-FICs in management of medical records and reporting realized the standardized management of medical record, encoding of diseases, functioning and intervention, reporting of performance, and provided tools for billing, reimbursement and payment management of rehabilitation. It proposed to develop WHO-FICs based clinical data sets and big data to implement functioning-related Diagnosis Related Groups and case-mix statistics. Conclusion:With the systematic implementation of WHO-FICs in rehabilitation, the policy and theoretical framework at macro level had been developed. The mechanism of management and governance at meso level had been explored. The application modules and approaches at micro level had been established. A scientific and effective overall solution had been proposed to enhance the scientific, standardized, refined and informatization level, strengthen the level and governance capacity, and improve the quality, safety and the coverage of rehabilitation services.

ABSTRACT

Objective:To investigate the rehabilitation human resources in Shanghai. Methods:Based on World Health Orgnization Rehabilitation in Health Service System: Action Guide, Rehabilitation Information Collection Template of Supporting Tools for Systematic Assessment of Rehabilitation Status was implemented by Shanghai Rehabilitation Medical Association in accordance with the requirements of Shanghai Rehabilitation Treatment Quality Control Center to investigate the number and knowledge structure of rehabilitation-related practitioners in Shanghai. Results:Totally, 311 medical institutions were investigated and 254 institutions set up rehabilitation medicine department, accounting for 82.47%. There were 1414 rehabilitation practitioners and 528 registered rehabilitation physicians, accounting for 37.34%; among them, senior, intermediate and junior professional titles were 142 (26.89%), 262 (49.62%) and 124 (23.48%), respectively. There were 2668 rehabilitation therapists, among which the senior, intermediate and junior professional titles were 11 (0.41%), 461 (17.28%) and 2196 (82.31%), respectively. There were 1614 rehabilitation nurses, among which the senior, intermediate and junior professional titles were 13 (0.81%), 476 (29.49%) and 1125 (69.70%), respectively. There were 2.17 rehabilitation physicians, 11.11 rehabilitation therapists and 6.65 nurses per 100 000 population, which is nearly 1/5 of the international level. There were 121 institutions without rehabilitation medical practitioners and 40 multi-point rehabilitation medical practitioners. Conclusion:There is a big gap in rehabilitation physicians, therapists and nurses in Shanghai, compared with the international level. Based on the imperfect occupational series and qualification certification of physiotherapists, occupational therapists, speech therapists and other specialties, it is suggested to conduct targeted job training in multiple channels and forms, especially to strengthen standardized job training and rehabilitation transformation training for rehabilitation practitioners. It is needed to promote the standardized training of resident and specialist rehabilitation practitioners more quickly to meet the needs of clinical rehabilitation work.

ABSTRACT

Knee osteoarthritis is a common chronic degenerative disease in the elderly. Its occurrence and development are closely related to biomechanical factors. The force of knee joint is affected by different factors, such as joint morphology, lower limb alignment, muscle contractions, external load, soft tissue traction and so on. Due to the limitation of in vivo measurement, biomechanical parameters based on motion analysis techniques have been widely used in clinical research. At present, biomechanical parameters which are widely studied and applied in clinical research include knee adduction moment, knee adduction impulse, knee flexion moment, and knee varus thrust. It is important to observe the changes of knee joint biomechanical parameters during the occurrence and development of knee osteoarthritis for researching etiology, diagnosis, intervention and treatment.

ABSTRACT

Atherosclerosis is one of the causes of many cardiovascular diseases. Lipid metabolism disorder is an important risk factor for atherosclerosis. Lipase-targeted screening may help discovery of hypolipidemic and anti-atherosclerotic drugs. Traditional methods for enzyme-based screening exhibit drawbacks of tedious operation steps, reduced enzyme activity, slow mass transfer, as well as high false positive rate. In this paper, an integrated perfusion enzyme affinity selection system based on hollow fiber was constructed to screen hypolipidemic and anti-atherosclerotic compounds from traditional Chinese medicines, and the total saponins of Kudingcha were taken as a case. First, we built a hollow fiber based perfusion system and optimized the methodology for enzyme affinity selection. Then, two active compounds of kudinosides A and C were identified as potential lipase inhibitors from the total saponins of Kudingcha by the proposed system. Last, the activity of kudinosides A and C was verified by lipase inhibitory assay and formation of foam cell model induced by low density lipoprotein aggregates, exhibiting the reliability of the system. This platform shows the advantages of integration, fast mass transfer, simple operation, low cost, as well as improved throughput and efficiency, which is especially suitable for rapid screening active components from traditional Chinese medicine.

ABSTRACT

OBJECTIVE@#To investigate the effect of lncRNA-CASC2 (CASC2) /miR-155-5p/APC axis to the progression of non-Hodgikn lymphoma (NHL).@*METHODS@#The expression level of CASC2 and miR-155-5p in NHL cell lines were examined by qRT-PCR. Dual-luciferase reporter gene assay was used to verify the relationship between miR-155-5p, CASC2 and APC. The effects of CASC/miR-155-5p/APC axis to the proliferation, invasion and apoptosis of NK-92 cells were detected by MTT, Transwell assay and flow cytometry assay, respectively.@*RESULTS@#CASC2 was downregulated in NHL cell lines. Overexpression of CASC2 could inhibit the proliferation and invasion of NK-92 cells, and promote its apoptosis. Dual-luciferase reporter gene assay confirmed that there was a targeting relationship between miR-155-5p, CASC2 and APC. The restoration experiments proved that knockdown of both miR-155-5p and CASC2 or APC could restore the inhibitory effect of miR-155-5p silencing to the biological behavior of NK-92 cells.@*CONCLUSION@#Overexpression of CASC2 suppresses the proliferation and invasion of NK-92 cells, promote the apoptosis of NK-92 cells via targeting miR-155-5p and upregulating APC expression.

ABSTRACT

Cardio-cerebral vascular disease induced by atherosclerosis is a serious cause of human health. The pathogenesis of AS is very complex,and the oxidized low-density lipoprotein( ox LDL) induced foam cells formation is considered to be the most important cytological change in AS. Based on the definition of " TCM chemical biology",we clarified the chemical composition of Ilex hainanensis,the effective substances of I. hainanensis on the activity of anti-AS were screened. Then we found that saponin BF523 had the good inhibitory effect on foam cell formation. In this research,we studied the BF523 as the research object to clarify the molecular target of the active compound of I. hainanensis by foam cell formation model. The results showed that BF523 significantly inhibited the oxidation of ox LDL-induced macrophage foaming and decreased the lipid content in macrophages. BF523 had inhibited the phagocytosis of ox LDL in macrophages by reducing the mRNA and protein levels of scavenger receptor CD36,thereby inhibiting the occurrence and development of AS. These findings not only clarified the mechanism of the inhibition of foam cell formation by saponin BF523,but also provided a useful exploration for the enrichment of the theory of " TCM chemical biology".

ABSTRACT

BACKGROUND@#Emerging evidences have indicated that the composition of gut microbiota was significantly influenced by central nervous system diseases. The digestion and metabolism disturbances of patients with amyotrophic lateral sclerosis (ALS) might be strongly associated with ALS; however, this has rarely been evaluated in these populations. This study was to evaluate bacterial and archaeal composition of gut flora and the corresponding metabolism performance of these micro-organisms in fecal samples of patients with ALS.@*METHODS@#A comparative study was performed on the intestinal microbiota from eight patients with ALS and eight healthy individuals at Huadong Hospital during November 2017 to April 2018; meanwhile, the metabolite concentrations of human endotoxin, short-chain fatty acids (SCFA), NO2-N/NO3-N, and γ-aminobutyric acid were also evaluated by spectrophotometry methods. The correlations between intestinal microbiota and metabolite concentration were compared between the two groups using one-way analysis of variance; the relative abundance of beneficial and harmful micro-organisms in fecal samples was also analyzed.@*RESULTS@#In general, the richness and evenness of bacterial and archaeal communities of healthy individuals were healthier than that of patients with ALS. The phylum Firmicutes/Bacteroidetes ratio, genus Methanobrevibacter showed an enhancive tendency in patients with ALS, whereas the relative abundance of beneficial micro-organisms (genera Faecalibacterium and Bacteroides) presented a significant decrease tendency in patients with ALS. In addition, the average concentrations of human endotoxin, SCFA, NO2-N/NO3-N, and γ-aminobutyric acid in patients with ALS and healthy individuals were 64.2 vs. 65.3 EU/mL, 57.5 vs. 55.3 μg/mL, 5.7 vs. 5.3 ng/mL, and 6.1 vs. 5.4 μmol/L, respectively, indicating that the digestion and metabolism functions of gastrointestinal tract of patients might decline with this disease.@*CONCLUSIONS@#The relative abundance of beneficial and harmful micro-organisms respectively showed decrease and increase tendency in patients with ALS.
