ObjectiveTo compare the clinical results of small surgical incision of bilateral spinous process and traditional open surgical incision in posterior single level lumbar interbody fusion,and assess the application value of the small surgical incision of bilateral spinous process in posterior single level lumbar interbody fusion.MethodsFrom December 2006 to June 2008,70 patients with lower lumbar vertebral diseases underwent single segment posterior lumbar interbody fusion.Patients were randomly divided into small surgical incision of bilateral spinous process group(Hereinafter referred to as small incision group) of 36 cases and 34 cases of conventional open group.Small incision group included 20 males and 16 females with an average age of 52.0 years.Traditional open group included 16 males and 18 females with an average age of 53.2 years.Two groups of operative time,blood loss,postoperative drainage,X-ray projection operation frequency,hospital stay,complication rate,creatine phosphokinase (CPK) level,multifidus cross-sectional area,postoperative low back pain visual analogue scale(VAS),Oswestry disability index(ODI),interbody fusion rate were compared,respectively.ResultsAll of 70 cases were followed up for 12-24 months (average,16).There were no statistically differences in the operation time,the number of X-ray projection,complication rate,and fusion rate between the two groups (P＞0.05),but there were significant differences in blood loss,postoperative drainage,the first day and the third day of postoperative the level of CPK,postoperative multifidus muscle cross-sectional area,postoperative low back pain VAS,hospital stay,and postoperative ODI between the two groups(P＜0.05).ConclusionSmall surgical incision of bilateral spinous process and traditional open surgical posterior lumbar interbody fusion were satisfied with the efficacy,but small surgical incision of bilateral spinous process with less trauma,shorter hospital stay,and rapid postoperative recovery.

Objective To analyze the correlation between smoking and occurrence of intracranial artery stenosis.Methods From June 2015 to May 2016,a total of 10 711 inpatients with transient ischemic attack (TIA) or ischemic stroke from 20 basel hospitals of nationwide were enrolled using a cross-sectional study,76 patients with unknown smoking and smoking cessation years were excluded.Finally,a total of 10 635 patients were enrolled.Transcranial color coded sonography and/or transcranial Doppler were used evaluate the intracranial artery stenosis lesions.The basic risk factors for cerebrovascular disease (age,sex,smoking and smoking years,whether smoking cessation and years,hypertension,diabetes,hyperlipidemia,atrial fibrillation,and family history of stroke) were recorded.According to the different smoking years,the smoking years were divided into five groups:non-smoking,smoking time ≤10-year,11 to 20-year,21 to 30-year,and >30-year groups for trend chi square test.According to the different smoking cessation years in the smokers,the smoking cessation years were divided into four groups:non-cessation,cessation time 1 to 10-year,11 to 20-year,and >20-year groups for trend chi square test.The effects of different smoking years and different smoking cessation years on the occurrence of intracranial arterial stenosis were analyzed.Results The incidence of intracranial artery stenosis in the smokers (40.4%[1 433/3 547]) was significantly higher than that in the non-smoking patients (29.4%[2 085/7 088]).There was significant difference (χ2=128.850,P<0.01),and the incidence of cerebral infarction in the smokers (91.6%[3 250/3 547]) was significantly higher than the non-smokers (85.0%[6 027/7 088]).There was significant difference (χ2=92.328,P<0.01).Smoking was an independent risk factor for intracranial artery stenosis (OR,1.603;95%CI 1.456-1.765;P<0.01).With the increase of smoking years,the detection rate of intracranial arterial stenosis increased gradually (trend χ2=115.437,P<0.01).Whether giving up smoking had no significant effect on the incidence of intracranial artery stenosis in patients with ≥20 years of smoking (trend χ2=1.043,P=0.307).Conclusions Smoking is an independent risk factor for affecting intracranial artery stenosis;the risk of disease increases with the number of smoking years.Long-term smokers (≥20 years) cannot reduce the effect on intracranial artery stenosis,even if they give up smoking.

Objective To investigate the effect of serum lipid level on carotid artery stenosis in patients with ischemic cerebrovascular disease.Methods Using a multi-center cross-sectional study,10 711 consecutive inpatients with transient ischemic attack (TIA) or ischemic stroke diagnosed clearly in 20 stroke screening and prevention project base hospitals from June 2015 to May 2016 were enrolled.According to the results of carotid ultrasonography,1 560 patients with extracranial carotid artery stenosis rate≥50% screened were enrolled in the study.They were divided into a severe stenosis group (70%-99%) and a mild-moderate stenosis group (<70%).The distribution of total cholesterol (TC),triacylglycerol (TG),low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels in both groups of carotid stenosis patients were analyzed,and the quantitative classification was based on the normal range of serum lipids.The distributions of serum lipid levels in different grades in patients of both groups were compared with the non-parameter test.Results The incidence of dyslipidemia in the severe stenosis group was higher than that in the mild and moderate stenosis group.There was no significant difference between the two groups (54.4%[319/586]vs.48.3%[470/974],P<0.05).Dyslipidemia was an independent risk factor for severe carotid artery stenosis (OR,1.27,95% CI 1.24-1.30,P<0.01).The TC and LDL-C levels in patients of the severe stenosis group were significantly higher than those in the mild-moderate stenosis group (TC:3.98[3.31,4.82]mmol/L vs.3.91[3.31,4.53]mmol/L,LDL-C:2.48[1.86,3.14]vs.2.30[1.79,2.80];all P<0.01).With the increase of TC and LDL-C levels,there was significant differences between the severe stenosis group and the mild-moderate stenosis group (all P<0.05),and the proportions of TC >5.80 mmol/L (7.3%[43/586]vs.0.4%[4/974]) and LDL-C>3.12 mmol/L (26.3%[154/586]vs.10.0%[97/974]) in patients of the severe stenosis group were higher than those in the mild-moderate stenosis group (26.3%[154/586]vs.10.0%[97/974]).Conclusion The high LDL-C and TC levels may increase the incidence of severe carotid artery stenosis or occlusion.

Objective To investigate the differences of distribution characteristics and risk factors of large artery lesions in patients with ischemic cerebrovascular disease in different age groups in order to provide the basis for the prevention and treatment of stroke in different age groups.Methods From June 2015 to May 2016,a total of 10 711 consecutive inpatients with transient ischemic attack (TIA) and ischemic stroke from 20 centers nationwide were enrolled.Each 10 years was used as an age group from 40 years.All the patients were divided into 5 age groups.The differences of the different risk factors for cerebrovascular disease among the 5 groups were compared.All patients were separated by gender.The chi square test was used to compare the incidences of large artery stenosis of the intracranial and external and anterior and posterior circulation,and the number of vascular lesions in the same sex in different age groups.Results (1) The risk factors of elderly patients were mainly hypertension,diabetes mellitus,and atrial fibrillation (χ2=61.938,χ2=13.349,and χ2=55.940;all P<0.01).The smoking history,family history of cerebrovascular disease,and obesity were more frequent among the young and middle-aged people (χ2=131.505,χ2=7.298,and χ2=100.911,all P<0.01).(2) The linear trend chi square test results showed that the proportion of multivessel diseases in female and male extracranial arterial lesions increased gradually with the increase of age.(χ2=54.799,χ2=161.370,all P<0.01).The proportion of multivessel diseases in the intracranial artery in female decreased gradually (χ2=5.328,P=0.021),and that in male did not have obvious trend of change (χ2=0.289,P=0.591).(3) The linear trend chi square test results showed that the incidence of simple intracranial arterial stenosis in female and male intracranial arterial stenosis decreased gradually with the increase of age (χ2=20.090,χ2=42.351,all P<0.01),and the incidence of simple extracranial arterial stenosis increased gradually (χ2=40.311,χ2=90.698,all P<0.01).The incidence of both intracranial and extracranial artery stenoses increased gradually (χ2=12.077,χ2=45.887,all P<0.01).The incidence of simple posterior circulation vascular stenosis increased gradually in female (χ2=16.434,P<0.01),but that did not have obvious trend of change in male (χ2=1.701,P=0.192).The incidence of stenosis of both anterior and posterior arteries in female and male increased gradually (χ2=4.587,P=0.032;χ2=35.156,P<0.01).Conclusions The distribution of atherosclerotic lesions in ischemic cerebrovascular disease of the different age groups was different.No matter female or male patients,the majority of the young and middle-aged patients were intracranial artery lesions,and the elderly patients were mainly extracranial artery lesions.The majority of elderly women had posterior circulation artery lesions.Understanding the characteristics in patients with intracranial arterial lesion in different age groups will help to develop individualized stroke prevention and treatment strategies for the population of different age groups.

Objective:To investigate the prevalence of estimated glomerular filtration (eGFR) and risk factors among middle-aged and elderly residents in Beijing.Methods:In August-December of 2017, 6 549 residents aged 45-79 years old were randomly selected in the study by stratified multi-stage cluster sampling method. The investigation was performed by questionnaire, physical examination and laboratory tests. The contents of questionnaire included the demographic characteristic and prevalence of chronic disease. Blood pressure was tested. Fasting venous blood was collected to test the level of total cholesterol (TC), high density lipoprotein cholesterol (HLDL), low density lipoprotein cholesterol (LDL), triglyceride (TG), fasting blood-glucose (FBG), blood creatinine (Cr) and serum uric acid (UA). The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was used to estimate GFR(eGFR). The decreased GFR was defined as eGFR less than 60 ml/min per 1.73 m 2. The statistical software SPSS 20.0 was used for analysis. The general linear model, test of independence of rows and columns, logistic regression for complex samples were generalized. The weighted mean and weighted rate were analyzed. Results:The average level of eGFR was (100.51±0.54) ml/min per 1.73 m 2. The rate of decreased GFR was 1.28%, and it showed a higher rate in subjects aged 70-79 years-old, living in urban area, with history of cardiovascular disease, hypertension, diabetes mellitus, hyperuricemia (4.53%, 1.57%, 2.90%, 2.27%, 2.12% and 4.62%; F=30.827, 10.588, 11.466, 34.693, 6.788,51.643, all P<0.05) . Logistic regression analysis of complex sampling showed that 70-79 years old ( OR=4.435, 95 %CI:2.402-8.191), living in urban area ( OR=3.145, 95 %CI: 1.540-6.420), hypertension ( OR=4.663, 95 %CI:2.177-9.988), hyperuricemia ( OR=6.751, 95 %CI:3.363-13.553) were associated with decreased GFR (all P<0.05). Conclusion:The prevalence of the decreased eGFR among middle-aged and elderly residents in Beijing is higher than the average level in the eastern part of China. Hypertension, hyperuricemia, the old age and living in urban are risk factors of decreased GFR.

Objective To investigate the distribution characteristics and risk factors of intracranial and extracranial aterial lesions in Chinese patients with ischemic stroke . Methods In this multi‐center study ,2 310 continuously inpatients with ischemic stroke diagnosed in 20 stroke screening and prevention project base hospitals from June 2015 to M ay 2016 were enrolled . Carotid ultrasonography and transcranial color‐coded sonography or transcranial Doppler were performed in all patients to confirm the presence of cerebral artery stenosis or occlusion . According to the distribution of lesions ,the subjects were divided into 2 groups :the simple intracranial artery stenosis group and the simple extracranial artery stenosis group . T he difference of risk factors between the two groups was compared . Results Of the 2 310 patients with ischemic stroke ,1 516 ( 65 .6% ) had simple intracranial artery stenosis and 794 ( 34 .4% ) had simple extracranial artery stenosis . T he incidence of anterior circulation artery stenosis was higher in the group of intracranial artery stenosis than that in the extracranial artery stenosis group ( 68 .1% vs 48 .7% , P ＜0 .001) . Posterior circulation artery stenosis and combined anterior with posterior circulation artery stenosis were more common in patients with extracranial artery stenosis group than those in intracranial artery stenosis group ( 36 .4% vs 22 .1% ,14 .9% vs 9 .8% ;all P ＜0 .001) . Univariate analysis of risk factors for stroke showed that patients with intracranial arterial stenosis had a higher prevelence of hypertension , diabetes ,obesity ,and family history of stroke ,and their systolic blood pressure ,diastolic blood pressure , body mass index ( BM I) ,fasting blood‐glucose ,glycosylated hemoglobin ,triacylglycerol ,total cholesterol , and low‐density lipoprotein cholesterol were significantly higher than those in the extracranial arterial stenosis group ( all P ＜ 0 .05 ) . T he proportion of elderly ( ≥ 65 years old ) ,male and smokers in the extracranial arterial stenosis group was significantly higher than that in the intracranial arterial stenosis group ( all P ＜0 .05) . Multivariate logistic regression analysis showed that elderly ( ≥65 years old) ,male , and smoking history were independent risk factors for extracranial arterial stenosis ( OR＝ 2 .012 ,1 .637 , 1 .325 ,respectively ;all P ＜0 .05) . While hypertension ,diabetes ,less physical activity ,and high BM I levels were independent risk factors for simple intracranial arterial disease ( OR ＝ 1 .301 ,1 .252 ,1 .248 ,1 .030 , respectively ;all P ＜0 .05) . Conclusions There are significant differences in the distribution characteristics and risk factors of intracranial and extracranial aterial lesions in patients with ischemic stroke in China .
