BACKGROUND:Swel ing after knee arthroplasty can produce tension bul ae, worsen pain, and even block venous return. Thus, intraventricular pressure of osseous fascia increases, which can block arterial blood circulation, even induce osteofascial compartment syndrome.
OBJECTIVE:To evaluate efficacy of Cryf/cuff Systems and intermittent cold compress with hypertonic saline fol owing total knee arthroplasty.
METHODS:A total of 60 patients with unilateral total knee arthroplasty were randomly assigned into two groups. Persistent freezing group received treatment with Cryo/cuff Systems after arthroplasty, and intermittent cold group received intermittent cold compress with hypertonic saline after arthroplasty.
RESULTS AND CONCLUSION:Significant differences in circumference differences in superior patel ar pole, patel ar midpoint, and thickest point of gastrocnemius muscle were detected between persistent freezing group and intermittent cold group at 1 and 2 days after total knee arthroplasty (P<0.05), but no significant difference was detectable at day 3. Visual analogue scale scores at rest and during activity were significantly lower in the persistent freezing group than those in the intermittent cold group at 1 and 2 days after total knee arthroplasty (P<0.01), but no significant difference was visible at day 3. Range of motion was better in the persistent freezing group than that in the intermittent cold group at 1, 2 and 3 days (P<0.01), but no significant difference was observed at 1 and 2 weeks. Mean skin temperature was higher in the persistent freezing group than that in the intermittent cold group at 3 days (P<0.05). Results suggested that Cryf/cuff Systems could lessen tissue swel ing and pain, increased range of motion compared with intermittent cold compress with hypertonic saline at 1 and 2 days after total knee arthroplasty, but no significant difference was detected at day 3. That is, intermittent cold compress with hypertonic saline can reach the same effect as Cryf/cuff Systems at day 3.

Student awareness of rehabilitation medicine theory was still weak after learning for some time. We tried to impart rehabilitation concepts and thoughts to students during the course of rehabilitation technique. Following one controlled and randomized study, the Results of treatment group was more significant than that of controls.

Objective To investigate the role of ileocecal valve in children patients with intussus-ceptions by colonoscopy after pneumatic air enema reduction. Methods A total of 106 intussusceptions chil dren patients, who recovered with pneumatic air edema reduction, were recruited to the study. They underwent colonoscopy within 12 hours after reduction. The control group was composed of 103 children patients with both diarrhea and hematochezia. There was no significant difference in age, sex or weight between the two groups.Colonoscopic findings were recorded in terms of slack, swelling, prolapsus, lymphoid hyperplasia and mucosal lesions in ileocecal valve. Results In patients with intussusceptions, the rates of ileocecal valve slack, swelling including prolapsus, lymphoid hyperplasia and mucosal lesions were 61.3%, 33. 9%, 100. 0% and 31.1%, respectively, which were significantly different with those of the control group (P ＞ 0. 05 ). When further divided intussusceptions patients into groups with age more than 1 yr or less, significant differences were also observed in regarding of these features. Conclusion There is a close relationship between morphological and functional changes in ileocecal valve and intussusceptions in children. Ileocolic intussusceptions in patients younger than 1yr is more likely to be due to slack of ileocecal valve, while that in patients older than 1yr is mainly due to swelling or prolapse of ileocecal valve, represented by ileocecal intussuception.

Sleep apnea syndrome (SAS) is an independent risk factor for atherosclerosis and stroke. Studies have shown that the incidence of SAS increases significantly after stroke.This article reviews the mechanism of atherosclerosis caused by SAS and the characteristics and research progress of sleep apnea after stroke.

Objective To investigate the application of delayed sternal closure (DSC) following neonatal cardiac surgery.Methods We retrospectively analyzed clinical data of 360 neonatal patients underwent cardiac surgery through median sternotomy in Guangdong General Hospital between June 2009 and June 2014.These neonates were divided into 2 groups:DSC group (190 cases) and non-DSC group(170 cases).Comparing the differences between 2 groups,we analysed the application of DSC following neonatal cardiac surgery and the effect of DSC on surgical site infection.Results The cardiopulmonary bypass time,cross clamp time and mechanical ventilation time were longer in DSC group than in non-DSC group.The mortality rate in the DSC group(20.53％) was markedly higher than that in the non-DSC group(5.29％).However,there was no statistical difference in the incidence of sternal wound infection between 2 groups.Conclusion As an effective treatment for neonates with severe cardiac surgery,DSC doesn' t increase the incidence of surgical site infection.

Objective To investigate the feasibility of using synbiotics and probiotics to prevent and cure intestinal dysbacteriosis after burn. Methods Burned rats were fed with synbiotics and probiotics reagents, and the amounts of major intestinal florae in caecal contents were detected. Results The major physiological anaerobes were mostly stable, and the conditioned pathogens had no abnormal. Conclusion The micro-ecosystem regulator can quickly supplement the decreased physiological anaerobes caused by burning,and avoid the occurrence of dysbacteriosis.

ObjectiveTo investigate the situation of the rehabilitation service for the stroke residents of communities in Beijing, and explore the related factors of rehabilitation training for stroke patients in community. Methods216 stroke residents and their 197 families at Chongwen district in Beijing were surveyed with questionnaires. Results and ConclusionThe awareness of rehabilitation in stroke patients obviously correlated with rehabilitation training accepted in hospital, while their rehabilitation in community correlated with the development of community-based rehabilitation and the rehabilitation accepted in hospital.

ObjectiveTo explore the effect of the appropriate rehabilitation technique on social function for stroke residents in community.Methods38 residents suffering from stroke were treated mainly using the appropriate rehabilitation technology mainly derived from conductive education. The patients were assessed by Functional Activities Questionnaire (FAQ) before and 3 months after intervention.ResultsThe social function of post-treatment improved significantly comparing to pre-treatment.ConclusionThe appropriate rehabilitation technology is effect for stroke residents in community.

Objective To study the short and long-term effects of vocational rehabilitation on the disabled with low job satisfaction.Methods 66 disabled workers were divided into control group (n=32) and treatment group (n=34). The treatment group accepted physical,occupational and psychosocial therapy for 4 weeks. All the workers were assessed with Minnesota satisfaction questionnaire before treatment,3 and 12 months later. Results The total, internal and external satisfaction significantly improved in treatment group after treatment (P<0.01), except the internal satisfaction 1 year later (P>0.05). Conclusion Specific vocational rehabilitation programme may promote the inclusion of disabled workers into the workplace.

UNLABELLEDOBJECTIVE This study aims to construct a chitosan (CS)-polycaprolactone (PCL)-hydroxyapatite (HA) composite biomimetic scaffold to replace condyle and to explore the tissue engineering applications of condylar.

METHODSA resin mold of the mandibular condyle was prepared by using rapid prototyping techniques. A mandibular condylar integrated biomimetic scaffold model was prepared by solution casting-ice Lek. PCL and CS were mixed at a ratio of 4:1. HA at quality ratios of 40%, 50%, 60%, and 70% was added to groups a, b, c, and d, respectively. The microscopic morphology, porosity, infrared spectra, X-ray diffraction pattern, and mechanical properties of the scaffold were observed.

RESULTSThe scaffold that includes both upper and lower parts displayed the same features (i.e., shape, yellow-white appearance, and hard texture) as the mandibular condyle. Scanning electron microscopy showed that the composite scaffold had a 3D network spatial structure, 70%-85% porosity, and 10-200 µm pore size. Infrared spectra showed that the peak intensity reduced with decreasing HA content. X-ray diffraction showed that the diffraction peak decreased with increasing HA content. Suitable tensile and compressive and flexural strength were discovered in the presence of 50% HA.

CONCLUSIONThe scaffold prepared by solution casting-ice Lek shows favorable comprehensive features and is expected to replace human condylar.
