Objective To study the process of foam fractionation of polyphyllin in semi-batch mode. Methods Taking enrichment ratio, recovery rate of polyphyllin, and purity ratio as the performance criteria and using single examining method to examine the operational parameters, i.e. operation mode, air flow rate, initial feed concentration, solution pH value, initial feed height and temperature on separation performance. The optimal conditions of the process were obtained finally. Results The separation performance is good when gas flow rate is 400 mL/min, initial feed concentration (polyphyllins content) is 0.3 mg/mL, pH value is 7, feed height is 30 cm, and feed temperature is 40 ℃. The enrichment ratio is 25.7, recovery ratio is 42.1%, and the foam liquids purity of total polyphyllin is 41.4%, which is 4.5 times higher than that in feed purity. Conclusion Foam fractionation technique could be applied to separate polyphyllin.

Objectives To investigate the effect of leptomeningeal anastomoses (LMA) compensation of anterior cerebral artery (ACA) on the size of cerebral infarction in patients with chronic middle cerebral artery occlusion (CMCAO) and to analyze the correlation between middle cerebral artery (MCA) velocity and cerebral infarction area.Methods From June 2014 to June 2016,35 consecutive patients with CMCAO from the Department of Neurology,Yanbian University Hospital and 74 with CMCAO from the Department of Neurology,Beijing Xuanwu Hospital,Capital Medical University were enrolled retrospectively.All patients were diagnosed as CMCAO on one side and MCA was normal on the other side with transcranial Doppler (TCD) or transcranial color-coded sonography (TCCS) and confirmed by digital subtraction angiography (DSA).They were divided into either a LMA group (n=49) or a non-LMA (NLMA) group (n=60) according to the DSA revealed ACA.TCCS and/or TCD were used to measure and record the peak systolic velocity (PSV) and mean flow velocity (MFV) of the contralateral and ipsilateral MCA,and the ratios of bilateral PSV were calculated.They were divided into 4 grades,including normal brain tissue,cerebral lacunar infarction,small and moderate cerebral infarction,and large cerebral infarction according to the findings of diffusion-weighted imaging (DWI).Mann-Whitney test was used to compare the differences of cerebral infarction areas between the LMA group and the NLMA group,and Spearman rank correlation analysis was used to analyze the correlation between the MCA blood flow parameters of the ipsilateral side and the cerebral infarction area.Results (1) The patients with stroke accounted for 90.0% (n=54) in the NLMA group,and it was significantly higher than 71.4% (n=35) in the LAM group.There was significant difference between the two groups (P<0.05).(2) The severity of cerebral infarction in the NLMA group was significantly higher than that in the LMA group.DWI revealed that the LMA group was mainly lacunar infarction (51.0%,n=25),the NLMA group was mainly small and moderate infarction (45.0%,n=27),the incidence of large infarction (21.7%,n=13) was higher than that in the LMA group (4.1%,n=2).The difference between the two groups was statistically significant (P<0.01).(3) The cerebral infarction area in patients of the NLMA group showed moderately negative correlation with PSV of MCA (r=-0.736,P<0.01),and increased with the increase of contralateral side of PSV/ipsilateral side of PSV,there was a high positive correlation (r=0.849,P<0.01).Conclusion The compensatory function of meningeal branches of the anterior cerebral artery in patients with CMCAO was associated with the severity of cerebral infarction.The decreased MCA blood flow velocity on the ipsilateral side had a significant correlation with cerebral infarction area.

Objective To examine serum lipid levels and to investigate the risk factors of dyslipidemia in children and to study the indices of screening test for dyslipidemia of children in Beijing.Methods Serum total cholesterol(TC),triglyceride(TG),high density lipoprotein-cholesterol(HDL-c) and low density lipoprotein-cholesterol(LDL-c) were detected by HITACHI 7060 automatic biochemical analyzer in Beijing students.Body height, weight,upper body height,waist circumference,upper arm circumference and blood pressure were measured.Body mass index(BMI) was calculated according to the measurement of body height and weight.Waist-to-height ratio(WHR) was also calculated.Then a Logistic regression analysis and ROC study were conducted to examine the relationship between the above indices and dyslipidemia.Results Of 962 students,107 were found dyslipidemia.The prevalence rate was 11.12%.The upper body height,upper arm circumference,BMI,WHR,systolic pressure and diastolic pressure in children with dyslipidemia were higher than those of normal subjects(P

Objective To evaluate the mid-term tollow-up results of cervical artificial disc replacement (CADR) for cervical degenerative disc disease,and to explore whether it can reduce the occurrence of adjacent segment degeneration (ASD).Methods A prospective comparative study of 93 patients who underwent CADR or anterior cervical decompression and fusion (ACDF) for cervical degenerative disc disease were conducted.All patients were followed up for more than 6 years.The Japanese Orthopaedic Association (JOA) score,neck disability index (NDI),Odom's scale,X-rays and magnetic resonance imaging (MRI) were used to evaluate the clinical and radiologic results.Results Twenty eight patients who underwent CADR and 35 patients who underwent ACDF had complete follow-up data.At final follow-up,the JOA score and NDI improved significantly in both groups.Between the two groups,there was no significant difference in terms of JOA score,NDI and Odom's scale.The sagittal alignment was well maintained in both groups.The total cervical spine range of motion (ROM) had no significant change for the CADR group,whereas,it significantly decreased for the ACDF group.The ROM at the replacement level of CADR patients decreased from 9.5° ± 3.7° before operation to 7.0° ± 3.0° 3 months after operation,and it was maintained to 6.6° ± 4.1° at final follow-up without significant decrease.Lateral radiographs and T2-weighted MRI showed the incidence of ASD in CADR group was significantly lower than that in ACDF group.Conclusion The six-year follow-up results of CADR are basically satisfactory.Compared with ACDF,it could better preserve physiological motion and biomechanics of cervical spine,and reduce the incidence of ASD.
