Objective To understand the level and correlation of biochemical joint indicators in stroke high risk population in Yi-chun City ,and the differences in biochemical joint indicators between community and rural stroke high risk populations .Methods Three hundreds and fifty-four high risk people during stroke screening in 2015 and 2016 included 115 community high risk cases , 239 rural cases ,226 males and 128 females ,aged 40 to 86 years old .Thirty-one cases of non-stroke high risk included 15 cases of male and 16 cases of female ,aged 28 to 85 years old .Seven biochemical joint indicators were detected and statistically analyzed ,in-cluding glucose (GLU) ,glycated hemoglobin(HbA1c) ,total cholesterol(TC) ,triacylglycerin (TG) ,high-density lipoprotein choles-terol(HDL-C) ,low-density lipoprotein cholesterol (LDL-C) and homocysteine (Hcy) .Results In the comparison between stroke high risk population and non-high risk populations ,CH ,TG ,LDL-C and Hcy had statistically significant difference (P< 0 .05) . HDL-C ,GLU ,HbA1c had no statistically significant difference (P>0 .05) .In the comparison between community and rural stroke high risk populations ,CH ,TG ,LDL-C and GLU had statistically significant difference (P<0 .05);HDL-C ,Hcy and HbA1c had no statistically significant difference (P>0 .05) .Conclusion The increase of CH ,TG ,LDL-C and Hcy is the risk factors of stroke , while CH ,TG ,LDL-C and Hcy are the interventional risk factors and play an important role in its early diagnosis ,treatment and prognosis .The key to prevent stroke is the healthy diet ,good living habits ,moderate exercises ,and regular monitoring of CH ,TG , LDL-C ,Hcy and GLU ,forewarning ,prevention and treatment ,which can avoid the occurrence or less occurrence of stroke ,thus re-duces the its incidence rate ,greatly decrease the morbidity ,recurrence rate ,and reduces the familial and social burden of manpower , material resources and financial resources .

Object To establish a method for chemical pattern recognition on the quality assessment of Radix Astragali. Methods The contents of astragaloside in 18 samples of Astragalus Linn. in different species and origins were determinated by dual-wavelength TLCS method. The developing solvent was CHCl 3-MeOH-H 2O (65∶30∶10,), the UV detection was set at ? s=390 nm; ? R=590 nm. Astragaloside was regarded as the quality assurance of medicinal Radix Astragalus. Based on the TLCS method, the chemical data were obtained. Hierarchical clustering analyses were applied to the chemical pattern recognition. Results The content of astragaloside in Astragalus mongholicus (Bge.) Hsiao and A. membranaceus (Fisch.) Bge. was relatively higher than that in the other samples. This is consistent with the Pharmacopoeia of the People's Republic of China in which the two sorts of Astragalus Linn. were regarded as goods. Conclusion This method is a practicable in the quality assessment of Radix Astragali.

Objective:To explore the related factors influencing the length of hospital stay(LOS) of pregnant women with heart disease (PWHD) after cesarean section.Methods:A total of 306 patients with PWHD who underwent cesarean section from January 2012 to March 2019 were collected. Among them, 203 patients had not undergone heart surgery (uncorrected group) and 103 patients who had undergone heart surgery (corrected group) during the same period. Demographic, perioperative and postoperative data were recorded. Predictors associated with postoperative LOS were determined using univariate and multivariate linear regression analysis models.Results:(1) The median LOS after cesarean section in the uncorrected group was 6 days (5-8 days). The results of univariate linear regression analysis showed that 38 parameters had significant impact on LOS ( P<0.05). The results of multivariate linear regression analysis showed that 5 parameters were independent risk factors for prolonged LOS in the uncorrected group; among them, the median LOS in uncorrected group with hypertensive disorders of pregnancy was 3 days longer than that in patients with PWHD alone [7 days (5-8 days) vs 4 days (4-5 days), β=0.195, P=0.001]; the median LOS in uncorrected group with high serum creatinine was 3 days longer than normal patients [7 days (5-13 days) vs 4 days (4-5 days), β=0.145, P=0.015]; the LOS of patients who chose general anesthesia was 2 days longer than that of patients who chose spinal anesthesia [6 days (4-8 days) vs 4 days (4-5 days), β=0.154, P=0.007]; the LOS of patients with postoperative pulmonary infection was 4 days longer than that of patients without pulmonary infection [8 days (5-15 days) vs 4 days (4-5 days), β=0.269, P<0.01]; the LOS of patients who admitted to ICU after surgery was 2 days longer than that not admitted patients [6 days (5-8 days) vs 4 days (4-5 days), β=0.268, P<0.01]. (2) The median LOS after cesarean section in corrected group was 4 days (4-5 days). The results of univariate linear regression analysis showed that 8 parameters had significant impact on the LOS (all P<0.05). The results of multivariate linear regression analysis showed that 2 parameters, which were American Society of Anesthesiologists (ASA) grade ( β=0.198, P=0.028) and intraoperative blood loss ( β=0.285, P=0.003), were the independent risk factors for prolonged LOS in corrected group. Conclusion:Preoperative with hypertensive disorders of pregnancy, preoperative creatinine increase, intraoperative general anesthesia, postoperative pulmonary infection, and postoperative admission to ICU are independent predictors of prolonged LOS in uncorrected patients with PWHD; ASA classification and intraoperative bleeding are independent predictor of prolonged postoperative LOS in patients with corrected PWHD.
