Objective To evaluate the interventional of bare-handed core muscle strength training and the sling exercise therapy (SET) on low back pain.Methods The soldiers of an Air Force Station who suffered from low back pain participated in the study.One hundred and forty-four patients were equally divided into three groups: the core muscle strength group (using core muscle strength training and the general physical therapy), the SET group (using SET and general physical therapy), and the control group (using the general physical therapy).All the groups were tested for 6 weeks.Questionnaires were distributed to the three groups before intervention, two weeks, four weeks and six weeks after intervention in order to find out about the degree of LBP, lumbar function and activity of these cases.Changes in the lumbar muscle strength were observed.Results The number of the patients who completed the test included 43 cases in the bare-handed core muscle strength group, 43 cases in the SET group and 44 cases in the control group, respectively, the VAS scores were 3.25, the Roland scores were 5.83,the FFD scores were 8.58 of the bare-handed core muscle strength group;the VAS scores were 3.30, the Roland scores were 5.93,the FFD scores were 8.10 of the SET group;the VAS scores were 2.41, the Roland scores were 3.03,the FFD scores were 7.40 of the control group.The LBP intervention efficiency of the three groups was 90.90%, 85.13% and 46.82%, respectively.There was no significant difference in indexes between the test groups(P>0.05).But compared with the control group,there was significant difference(P<0.05).Conclusion The bare-handed core muscle strength training and SET have obvious effects on LBP cases.According to their own infrastructure and facilities, military health care organizations in different environments can intervene in LBP cases with the bare-handed core muscle strength training or SET to alleviate the pain effectively.

Objective To study the risk factors of hematoma enlargement in acute hypertensive cerebral hemorrhage (AHCH) patients within 24 hours after onset. Methods A retrospective review of clinical data of consecutive patients with AHCH who met the inclusion and exclusion criteria and admitted from Mar. 2008 to Mar. 2013 was performed. The patients' data included patients' demography, previous medical history, clinical features, findings of CT, results of laboratory examinations, and the use of traditional medicines for promoting blood circulation. Patients were divided into hematoma enlargement group and non-hematoma-enlargement group. Univariate analysis was performed on the above factors first, and then with the statistically significant factors used as independent variables, hematoma growth as dependent variables, logistic regression analysis was performed to investigate the possible independent relevant factors for the early enlargement of hematoma in AHCH patients. The risk factors and enlargement of hematoma served as independent variables, the data of mRS scale obtained from 3-month follow up as dependent variables, logistic regression was then performed to investigate the influence of acute hematoma enlargement during 3-month follow up in AHCH patients. mRS 0-2 was assigned as good recovery, and mRS 3-6 as serious disability or death. The inspection level was ct=0.05. Results Among 256 patients, 43 (16.8%) were found to have hematoma enlargement. Univariate analysis showed the risk factors led to hematoma enlargement in AHCH patients were gender (male), Glasgow coma scale at admission, NIHSS (National Institute of Health Stroke Scale) at admission, course of disease, and liver function (AST). However, only two factors, namely gender (male) and course of disease, were the independent risk factors of the hematoma enlargement in AHCH patients according to the multivariate regression analysis. In addition, logistic regression revealed that the hematoma enlargement was the independent risk factor influencing the final outcome of AHCH patients, and the hematoma volume, NIHSS, and course of disease were the independent risk factors influencing the outcome of 3 month follow up. ConclusionsA male AHCH patient with shorter duration from onset to admission (within 2 hours) should alert attending physician there would be a risk of hematoma expansion. Larger amount of bleeding, enlarged hematoma, higher NIHSS and shorter duration from onset to admission herald a poor prognosis.

Objective:To evaluate the efficacy and safety of multimodal endovascular therapy for acute ischemic stroke in elderly patients.Methods:A total of 263 elderly patients with acute ischemic stroke were enrolled as research subjects from January 2017 to December 2018.Patients were divided into two groups: the intravenous thrombolytic therapy group and the endovascular therapy group.Treatment outcomes were compared by using the National Institutes of Health Stroke Scale(NIHSS)and the modified Rankin Scale(mRS).Results:Of 263 patients, 125 were in the intravenous thrombolytic therapy group and 138 were in the intravascular therapy group.The rate of good/excellent outcomes was higher in the endovascular treatment group than in the intravenous thrombolytic therapy group(97.8% vs.91.2%, χ2=5.713, P<0.05). The NIHSS score and mRS score were lower in the endovascular treatment group than the in intravenous thrombolytic therapy group[(2.3±0.3) vs.(6.0±1.8), (1.1±0.1) vs.(2.3±0.3), t=9.067 and 16.970, P<0.05]. There was no significant difference in the incidence of adverse reactions between the two groups(8.6% vs.8.0%, χ2=0.041, P>0.05). Conclusions:Multimodal mechanical thrombus retrieval is a safe and effective treatment for intracranial large vessel occlusion in acute ischemic stroke patients and should be recommended and promoted.

Objective To summarize the clinical characteristics and diagnosis and treatment of hemangioma of small intestine in children.Methods Location,pathology,clinical manifestation,diagnosis and treatment of 3 cases from our hospital and 44 cases reported in our courtry with hemangioma of the small bowel were analyzed from 1994 to 2004.Results These tumors locating in jejunum,ileum,duodenum as well as parts small intestine were 31.9%,42.6%,4.2% and 21.3%,respectively.Solitary and multiple tumors were 29.8% and 70.2% separately.The histopatholical report of 10 cases revealed that capillary,cavernous,mixed type hemangioma and hematolymphangioma were 2,6,1 and 1 cases,respectively.Thirty nine children presented with recurrent black stool.Five patients manifest in the form of intussusception.One child passed a bloody stool so massive as to cause shock.Small-bowel obstruction occurred in 5 cases.The hemoglobin of 38 patients were lower than 90 g/L.The incidence of preoperative diagnosis was only 10.6%.All of patients were performed operation.Conclusions The frequent locations of hemangioma of small intestine are in ileum and jejunum,and multiple tumors are common.The diseases are characterized as recurrent hematochezia with painlessness.Preoperative diagnosis of a small bowel hemangioma can be very difficult.The segments of small bowel with hemangioma resection are the most method of the treatment.
