目的 观察家庭式康复教育结合模式对脑瘫儿童发育情况的影响。方法 采用随机数字表法将38例脑瘫患儿分为实验组及对照组。2组患儿均给予常规日常康复,康复治疗师、引导式教师、特殊教育教师组成的团队共同对实验组内儿童功能情况进行评估,设计引导式教育课程,对无康复教育知识背景的专职护理人员进行课程培训,完成培训的护理员具体执行引导式教育课程,每天2次,每次60min,每周介入6日,持续半年。于治疗前、治疗后采用Gesell发展量表进行评测。结果 治疗前,两组患儿适应性行为、大运动、精细动作、语言、个人-社会行为5个领域指标组间差异无统计学意义(P>0.05);经介入半年后,两组患儿的适应性行为、大运动、精细动作、语言、个人-社会行为5个领域评分均优于组内治疗前水平(P <0.05),且实验组优于对照组(P <0.05)。结论 家庭式康复教育结合模式,对改善脑瘫患儿的多方面功能发展有重要意义,值得在专业人才资源缺乏的机构和社会中推广、应用。
Objective To observe the effect of the model of family rehabilitation education on the development of children with cerebral palsy. Methods 38 children with cerebral palsy were divided into experimental group and control group by random digital table method. Two groups of children were given routine daily rehabilitation. A team of rehabilitation therapists,guided teachers and special education teachers assessed the children's function in the experimental group,and designed guiding education course. The team offered curriculum training for full-time nurses without background knowledge of rehabilitation education,and the trained nurses implemented the guiding education course twice each day,60 minutes each time,6 days per week. The training lasted for six months. The Gesell development scale was used for evaluation before and after treatment. Results Before treatment,there was no statistically difference between 2 groups of children in 5 areas of adaptive behavior,exercise,fine motor,language and personal social behavior (P >0.05). After six months' intervention,2 groups of children were better than the pre-treatment level (P <0.05). The experimental group was superior to the control group (P <0.05). Conclusion The model of family rehabilitation education is of great significance to the improvement of the multifaceted function of children with cerebral palsy. It is worthy of popularization and application in institutions and societies which are lack of professional talent resources.

目的 了解广州市社区医务人员对颈动脉狭窄防治知识的认知程度、认知途径及对相关健康教育的需求情况。方法 对37家社区卫生服务中心194名广州市社区医务人员进行问卷调查,分析调查结果。结果 社区医务人员中52.58%能够指出颈动脉狭窄与脑卒中的关系,但对症状性颈动脉狭窄定义、颈动脉狭窄的外科治疗方法知晓率偏低(14.95%、18.56%),97.94%能够指出颈部彩超是颈动脉狭窄最常用的筛查方法,但对彩超结果判读、干预方法指导等方面内容掌握率偏低。对颈动脉狭窄知识来源目前最主要的是用药指南和药品说明书(33.89%)认为最有效获得颈动脉狭窄知识的途径是专题继续教育培训班(26.12%)。结论 社区医务人员已经形成了脑卒中和颈动脉狭窄的基本观念,但是不能达到足够的“深度”,通过开展多种形式继续教育,增进社区医务人员对颈动脉狭窄认知的广度和深度,引导和拓宽获得知识的途径将是必要和有效的。
Objective To understand the knowledge and needs of carotid stenosis prevention among community health workers in Guangzhou. Methods A Kirkpatrick model-based questionnaire survey was conducted among 194 health workers in community health service center in Guangzhou. Results 52.58% of the community medical staff could point out the relationship between carotid stenosis and stroke, but few of them could accurately point out the definition and surgical treatment of symptomatic carotid stenosis(14.95%,18.56%). 97.94% of them could pointed out that the most commonly used screening methods for cervical carotid stenosis, but most of them didn't know how to interpret the inspection result of color doppler ultrasound. Medication guide were the main knowledge source of carotid stenosis(33.89%) and post-graduate training was the most promising approach(26.12%). Conclusion Community health workers have formed the basic concept of stroke and carotid stenosis, but it was limited in extent. It is necessary to carry out various forms of continuing education to improve the level of awareness of community health workers on carotid artery stenosis.

Objective To construct a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem) and establish a nude mouse model of breast cancer with hepatic metastatic. Methods A gemcitabine-resistant variant of the breast cancer 4T1 cell line was induced by gradually increasing the concentration of gemcitabine; this variant is referred to in this study as 4T1/Gem. The proliferation suppression rates of 4T1 and 4T1/Gem cells were determined by using the CCK-8 essay to evaluate the drug resistance indices of the cell lines. Western blot analysis was used to detect P-gp protein expression. Under ultrasonography, a 4T1/Gem cell suspension was injected into nude mice to induce liver tumors. H&E staining was used to observe tumor pathology, and immunohistochemistry was used to detect the expression of ER, PR, HER-2, Ki-67, and P-gp. Results After 14 months of induction, a 4T1/Gem cell line is established successfully. The cell line can grow stably in culture liquid containing 40 μg/ml gemcitabine. The drug resistance index of 4T1/Gem is 788.547. Compared with the 4T1 cell line, the 4T1/Gem cell line can upregulate P-gp protein expression and successfully establish a nude mouse model of breast cancer with hepatic metastatic. ER, PR, and HER-2 proteins exhibit negative expression in the tumor tissue. The positive expression of P-gp and 10% of Ki-67 proteins is also observed. Conclusion This study successfully constructs a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem)and establishes a nude mouse model of breast cancer with hepatic metastatic, thereby providing an experimental basis for developing and treating a drug-resistant variant of breast cancer.
