RESUMO
OBJECTIVE： To optimize the water extraction technology of Chaihu anxin capsules. METHODS： Taking comprehensive scoring value of the contents of gallic acid，chlorogenic acid，puerarin，glycoside，rutin，cinnamic acid， quercetin and the yield of extract as investigation index， using multiple of adding liquid， soaking time， reflux time and extraction times as factors， water extraction technology of Chaihu anxin capsule was optimized by Box-Behnken response surface method based on single factor test. Validation test was conducted. RESULTS： The optimal extraction technology of Chaihu anxin capsules was adding 11 times of water， soaking for 10 h， extracting for 2 times， refluxing for 1.5 h each time. In validation test， the relative deviation of comprehensive scoring value to predicted value was 1.87％ for 3 batches of samples （RSD＜2％， n＝3）. CONCLUSIONS： The optimal extraction technology is simple， stable and suitable for further production of Chaihu anxin capsules.
RESUMO
OBJECTIVE： To evaluate the effects of clinical pharmacist-led ischemic stroke management， and to provide reference for chronic disease management. METHODS： Totally 184 patients with ischemic stroke who were hospitalized in neurology department of the First Hospital of Hebei Medical University from May to August 2018 were included prospectively， and then divided into control group （92 cases） and intervention group （92 cases） by random number method. Control group did not receive clinical pharmacist intervention. In the intervention group， clinical pharmacists were the leader in the pharmaceutical care during the hospitalization， the medication education at discharge， and pharmacy follow-up after discharge. The rate of medication compliance （antiplatelet drugs， antihypertensive drugs， hypoglycemic drugs and lipid-lowering drugs） and the rate of secondary prevention and control indicators of ischemic stroke， such as blood pressure， blood glucose [glycated hemoglobin （HbA1c）] and blood lipid [low-density lipoprotein cholesterol （LDL-C）] were investigated between 2 groups at 6 months after discharge. The incidence of adverse drug reaction and the rate of rehospitalization were compared between 2 groups at 6 months after discharge. RESULTS： The number of patients in the intervention group and the control group was 84 and 82， respectively. At 6 months after discharge， the compliance rate of antiplatelet drugs in the intervention group was 96.43％， which was higher than 95.13％ of control group， but the difference was not statistically significant. The good compliance rates of antihypertensive drugs， hypoglycemic drugs and lipid-lowering drugs in the intervention group were 92.86％， 91.67％ and 77.38％， which were higher than 78.57％， 69.70％ and 60.98％ of control group， with statistical significance （P＜0.05）. The qualified rate of index of blood pressure was 89.29％ in intervention group， which was higher than 76.79％ of control group， but the difference was not statistically significant. The qualified rates of HbA1c and LDL-C in the intervention group were 80.56％ and 66.67％， which were higher than 57.58％ and 48.785 of control group， with statistical significance （P＜0.05）. The incidence of total adverse drug reactions in the intervention group was 15.48％， which was lower than 20.73％ of control group， but the difference was not statistically significant. The total rehospitalization rate in the intervention group was 7.14％， which was lower than 17.86％ of control group， the difference was statistically significant （P＜0.05）. CONCLUSIONS： The management of ischemic stroke patients with clinical pharmacists as the leading factor can improve the patient’s medication compliance， improve the qualified rate of secondary prevention and control indicators of ischemic stroke， and reduce the rate of rehospitalization.
RESUMO
OBJECTIVE： To optimize the ultrasonic extraction technology for Jinjuan shengban capsules. METHODS： Using comprehensive score of indexes as transfer rate of gallic acid， chlorogenic acid， baicalin， aloe emodin and emodin methyl ether， with ethanol volume fraction， ultrasonic power， ultrasonic extraction time and liquid-material ratio as factors， the ultrasound extraction technology of Jinjuan shengban capsules was optimized by Box-Behnken response surface methodology based on single factor test. The validation test was conducted. RESULTS： The best extraction technology was 50-fold 70％ ethanol， extracting 40 min under 300 W. In validation test， average transfer rates of gallic acid， chlorogenic acid， baicalin， aloe emodin and emodin methyl ether were 85.92％， 86.37％， 92.76％， 90.84％ and 87.26％ （RSD＜3.57％，n＝3） in 3 batches of samples； comprehensive score was 88.95％， relative error of which to predicted value of 88.27％ was 1.10％. CONCLUSIONS： The response surface method combined with multi-index comprehensive scoring can be used to optimize the extraction technology of Jinjuan shengban capsules which is simple and stable.
RESUMO
This study was aimed to observe the effect of traditional Chinese medicine (TCM)Bu-Shen Gu-Jin Prescription (BSGJP) on the expression and action mechanism of interleukin-1 (IL-1) and tumour necrosis factor-alpha (TNF-α) in knee osteoarthritis (KOA) rabbit model. A total of 76 8-month healthy male New Zealand white rabbits were randomly divided into the control group, model group, TCM BSGJP group and western medicine group, with 19 rabbits in each group. Except the control group, improved Hulth modeling method was used in the animal model establishment. After 8-week consecutive medication, the serum, part of the synovial membrane tissues on the anterior side of the knee joint, articular cartilage and subchondral bone of the medial condyle of the femur were collected. Enzyme-linked immunosorbent assay (ELISA) was used in the content determination of IL-1 and TNF-α. The results showed that the narrowing of the joint space of the western medicine group were in between the model group and the TCM BSGJP group with obvious osteophyte formation. The TCM BSGJP group had slight narrowing of the joint space, mild rough of the articular cartilage surface, and slight osteophyte formation. The contents of IL-1 and TNF-α in the model group were higher than than of the control group (P < 0.01). Both medication groups were lower than the model group (P < 0.01). There was no significant difference between the two medication groups. It was concluded that BSGJP effectively reduced the secretion of IL-1 and TNF-α, delayed the deterioration of cartilage, which provided scientific experimental evidences for the clinical applications.
