Mesenchymal stem cells (MSC) are considered to have important value in the treatment of various diseases because of their low immunogenicity, transferability, and strong tissue repair capacity. Stromal cell derived factor-1 (SDF-1) and its receptor CXC chemokine receptor 4 (CXCR4) pathway plays an important role in migration of MSC. The induction of homing of MSC to retina by regulating SDF-1/CXCR4 may exert the curative effect on diabetic retinopathy to greatest exent.
Objective We aimed to describe the prevalence of metabolic syndrome, its epidemiological characteristics, and to analyse the relationship of waist-to-hip ratio (WHR) and body mass index (BMI) with metabolic syndrome (MS) among staff at Southeast University. Methods The data from the overall physical examination of 1979 staff were analyzed.Results The crude prevalence of MS were 21.7%,26.4% and 14.2% in the whole population, men and women respectively. The standardized rates were 14.7%,19.0% and 9.4%. The prevalence of MS in men was significantly higher than that in women(Plt;0.05). Both abdominal obesity and visceral obesity were positively correlated with the prevalence of MS(r=0.295, 0.248, P=0.000). Conclusion The prevalence of MS among staff of Southeast University has shown a significant increase in 2006. WHR and BMI are both correlated with the prevalence of MS.
目的 总结我院35岁以下青年人胃癌43例的诊治经验。方法 对43例患者临床特征、诊断及治疗进行回顾性分析。结果 手术40例，根治性切除14例，姑息性切除9例，胃空肠吻合6例，单纯探查11例，切除率57.50%。术后3个月内死亡5例，4～12个月内死亡18例，12～24个月内死亡8例，生存2年以上9例，5年以上3例。误诊26例，误诊率60.46%。结论 青年人胃癌发病率低，恶性程度高，病程短，转移早，早期诊断率低，误诊率高，治疗关键是提高早期诊断率。
Objective To explore the awareness of thrombolytic therapy for acute ischemic stroke in inpatients with a history of stroke and with a high risk of stroke. Methods From January to August 2012, using self-designed questionnaire, trained neurologists conducted the face to face investigation in 500 inpatients with a high risk of stroke, including those with a history of stroke in Department of Neurology in the Second Affiliated Hospital of Chongqing Medical University. Results A total of 467 valid questionnaires were recovered. Only 16.1% (75/467) patients were aware of thrombolytic therapy for acute stroke, of whom 50.7% (38/75) knew the time window of thrombolytic therapy. Awareness of thrombolytic therapy was higher in patients aged 56-70 years, with a higher level of education and income, and in those who knew at least 3 stroke warning signs and those with a history of stroke. While awareness of the time window of thrombolytic therapy was higher in those unmarried or widowed and with a history of stroke. Multiple logistic regression analysis showed that awareness of thrombolytic therapy was independently associated with age, education level, knowledge of stroke warning signs and a history of stroke; awareness of the time window was associated with marital status and a history of stroke (P<0.05). Conclusions Inpatients with a history of stroke and with a high risk of stroke in the Department of Neurology have poor awareness of thrombolytic therapy for acute ischemic stroke. It is necessary to improve the level of patients’ knowledge about thrombolytic therapy for acute stroke by health education.
ObjectiveTo investigate the influence of gender, age, activity level, and diameter of graft on the anterior cruciate ligament (ACL) reconstruction.MethodsBetween February 2012 and June 2017, 179 cases (111 males and 68 females) with an average age of 30.0 years (range, 11-63 years) were included in study. The patients underwent internal fixator removal at 2 years or more after single bundle ACL reconstruction with hamstring tendon autografts. All patients were sports injuries. The time from injury to operation ranged from 3 days to 26 years (median, 120 days). Lachman test and pivot shift test were positive. Univariate analysis was conducted on gender, age, post-operative activity level (Tegner score at the time of internal fixator removal), diameter of graft, and number of graft strands, and logistic regression was used to conduct multivariate analysis to screen the independent risk factors.ResultsAll patients were followed up 24-90 months (mean, 29.1 months). At last follow-up, Lachman test was positive in 25 cases and pivot shift test was positive in 28 cases. The KT-2000 side-to-side difference was –1-7 mm (mean, 1.89 mm). Eleven patients (6.15%) failed after ACL reconstruction. Univariate and multivariate analyses showed that the age, gender, post-operative activity level, diameter of graft, and number of graft strands were not risk factors for the failure of ACL reconstruction (P>0.05).ConclusionThere was no significant difference in the risk for ACL reconstruction failure among age, gender, and activity level. ACL reconstruction failure rate cannot be reduced by increasing the number of graft strands to increase the diameter of grafts.
