Results The awareness rate of early symptoms of stroke was generally low in all age groups. Conclusion Stroke patients were lack of awareness of early symptoms in Gansu, we should step up publicity efforts to enable more patients to receive early treatment and reduce morbidity and mortality.

Objective To investigate the awareness of knowledge about stroke rehabilitation in medical professionals in Gansu. Methods 520 professionals of neurology, neurosurgery, and others from 10 hospitals of different level were investigated with questionnaire. Results The awareness of the knowledge about stroke rehabilitation was different with the gender (χ2=17.50), education levels (χ2=66.35), professional levels (χ2=16.81), specialities (χ2=124.39) and duties (χ2=29.99) of the professionals (P<0.05). Conclusion It is necessary to improve the education of rehabilitation in hospitals.

Objective To investigate awareness of relatives about knowledge of rehabilitation for stroke. Methods 1082 relatives of patients with stroke from 10 hospitals in Gansu were investigated with self-designed questionnaire. Results A total of 1082 questionnaires were returned. The relatives knew some about the stroke rehabilitation. Their awareness of stroke rehabilitation were different with the ages,educated levels, and occupations (P<0.05). Conclusion It is necessary to improve the health education for relatives of stroke patients individually about post-stroke rehabilitation.

Objective To investigate the knowledge of stroke risk factors in the families of patients with stroke. Methods 1100 family members of stroke patients hospitalized in 10 hospitals of various levels in Gansu were investigated with self-designed questionnaire. Results Most families knew that the hypertension was a risk factor for stroke, and there was no significant difference among ages. 7.32% of the families knew all the 6 common risk factors for stroke, and 14.23% knew none of them. Hypertension, hyperlipidemia, diabetes as the risk factors for stroke was known most in the families finished higher education, and different with the education levels. Heart disease, smoking, consumption of alcohol as risk factors for stroke was known poorly whatever the careers of the families. Conclusion The families of patients with stroke know less about common risk factors for stroke in Gansu.

Objective To investigate the awareness of the negative emotions on the physical rehabilitation and psychological treatment of family members of stroke patients in Gansu. Methods 1100 stroke patients from 10 hospitals of different levels in Gansu were surveyed. Results Family members who thought negative emotions can affect the recovery of limb function accounted for 77.17%, and who thought psychological treatment was needed accounted for 83.46%. Conclusion Family members of stroke patients think that negative emotions affect the recovery of limb function and psychological treatment is needed.

Objective To investigate the knowledge about risk factors for stroke in stroke patients. Methods 1043 stroke patients in 10 hospitals were investigated with self-designed questionnaire. Results The rate of awareness of risk factors for stroke was: hypertension 61.55%, hyperlipidemia 40.27%, drinking 32.21%, smoking 30.11%, diabetes mellitus 28.67%, heart disease 23.11%. 6.42% knew all the 6 risk factors, and 20.13% did not know any risk factor. The rate of awareness of diabetes mellitus was different among various aged groups (P<0.01), and the rate of awareness of hypertension, hyperlipidemia, and diabetes mellitus increased with the years of education. Conclusion The stroke patients know less about the common risk factors for stroke, who need more health education.

Background Researches showed that triterpenoids,with a similar structure to lanosterol,has therapeutical effect on many systemic diseases,and lanosterol was determined to have a therapeutical effect on cataract recently.However,how the lanosterol plays effects on other eye diseases is still unelucidated.Understanding the distribution of lanosterol in ocular tissue is helpful for us to elucidate the relationship of lanosterol with eye diseases.Objective This study attempted to investigate the distribution of lanosterol synthase (LSS) and lanosterol in cornea,lens and retina tissue of rats and offer a basis for the targeting treatment of eye diseases.Methods Fifteen SPF male SD rats were sacrificed by excessive anesthesia to obtain the eyeballs.The relative expressions of LSS protein and gene in the cornea,lens and retina tissue of the rats were detected by Western blot and reverse transcription (RT)-PCR,respectively.Immunofluorescence staining technology was used to locate the distribution of LSS in cornea,lens and retina tissue.The contents of lanosterol in the cornea,lens and retina tissue were analyzed by liquid chromatograph mass spectrometer (LC-MS).Results No LSS protein and mRNA was expressed in the retinal tissue in normal rats.The mean relative expression of LSS protein in the lens and cornea was 0.43±0.05 and 0.25±0.03,respectively,showing a significant difference between them (t =-5.35,P＜ 0.01).The relative expression of LSS mRNA was 0.51 ±0.04 and 0.29 ±0.02 in the lens and cornea,respectively,with a stronger expression in the lens in comparison with the cornea (t =-8.34,P＜0.01).Immunofluorescence staining showed that LSS primarily located in corneal epithelial layer,stromal layer and endothelial layer as well as lens epithelial cells and shallow cortex layer and hardly expressed in retina,and no co-expression of LSS with the neuron marked by NeuN and the Müller cell marked by glutamine synthetase (GS) in retinal tissue.LC-MS analysis revealed that the contents of lanosterol in lens and cornea was (24.37 ±2.91) ng/mg and (5.31 ±0.58) ng/mg,respectively,with a significant difference between them (t =-11.13,P＜0.01).Conclusions LSS and lanosterol extensively distribute in cornea and lens of normal rats,but not in retina tissue.These results offer new strategies for the target treatment of relevant eye diseases.

Objective To investigate the knowledge of stroke risk factors, early symptoms, and rehabilitation in stroke patients. Methods 1043 cases with stroke were stratified randomly sampled from 10 hospitals at different levels in Gansu, and were surveyed with self-designed questionnaire. Results For risk factors for stroke, hypertension was the most aware (61.55%), 6.42% knew all the factors. For the prevention and treatment, reasonable diet was the most aware (56.18%), followed with giving up smoking and drinking (52.92%). For the early symptoms, dysaesthesia of one side body was the most aware (53.88%), and then the headache and dizzy (50.14%). It was less than 30% to know the blurring, nausea and vomiting, and stiff tongue, etc. as the early symptoms. 60% of the patients did not know any about the rehabilitation, 22% did not know if rehabilitation be needed. 80% of the patients with stroke chose medication regardless of family income, and rehabilitation was chosen less than 30%. Conclusion It is important to popularize the knowledge of risk factors, early symptoms, and rehabilitation of stroke.
