OBJECTIVE: To optimize the extraction condition of volatile oil from five medicinal materials in Rutongxiaojie granules and to optimize the inclusion process of the extracted volatile oil. METHODS: The extraction condition was evaluated by orthogonal test with the recovery of volatile oil as indicator; and the inclusion condition was evaluated with the comprehensive scores of recovery ratio of inclusion compound, the content of volatile oil in inclusion compound and the utilization ratio of the volatile oil as criteria. RESULTS: The optimum extraction condition was established as follows: the medicinal materials were soaked in 10 times volume of water for 1hour and distilled for 9h by steam distillation. The optimum inclusion condition was as follows: the proportion of volatile oil to ?-CD was 1∶8; the inclusion temperature was 30℃ and including time was 20min. CONCLUSION: Both the extraction condition and the inclusion condition were reasonable and feasible.

Objective To observe the changes of the blood pressure after intracerebral hemorrhage (ICH) in spontaneously hypertensive rats (SHRs) as well as the expressions of α2A-adrenergic receptor (AR) in center (brain tissue) and peripheral (renal tissue) α1A-AR and to investigate the correlation between α1A-AR/α2A-AR and blood pressure regulation in acute hypertensive ICH. Methads A total of 30 six-month-old male SHRs were randomly divided into a sham-operation group and ICH (day 1,3, 7 and 14) groups (n =6 in each group). Blood pressure was measured by the tail-cuff method. Collagenase Ⅳ was injected into caudate-puta-men nucleus to induce a model of ICH. The expressions of α1A-AR and α2A-AR were detected by using immunohistochemistry and reverse-transcription polymerase chain reaction. Results One day after ICH, the blood pressure was 195.4 ± 8.39 mm Hg, and it was significantly higher than 177.8 ± 8.69 mm Hg (P = 0. 000) before ICH and 184. 1 ± 3.76 mm Hg in the sham-operation group (P=0. 002). At day 3 it was 185.3 ±9.22 mm Hg, and it was lower than that at day 1. It was 177.7 ±5.62 mm Hg and 176.7 ±6. 06 mm Hg at day7 and 14 respectively, which almost returned to the normal level before ICH. The α1A-AR mRNA and protein in renal tissue at day 1 after ICH were 0. 91 ±0. 013 and 0. 944 ±0. 142%, respectively, They were higher than 0. 89 ±0. 018 and0. 779 ±0. 103% in the sham-operation group, and they reached the peak (0. 93 ±0.015, P =0.008; 1.526 ± 0.296%, P =0.010) at day 3. The α2A-AR mRNA and protein in brain tissue were 0. 93 ±0. 020 and 2.64 ±0. 293% at day 3 after ICH, and they were significantly higher than 0. 86 ±0. 019 (P =0. 001) and 1. 070 ±0. 155% (P = 0. 020), and0.87 ±0. 029 (P =0. 000) at day 1 after ICH and 1. 629 ±0. 488% (P =0. 023) in the sham-operation group. The changes of blood pressure in the ICH day 1 to day 7 grottos in SHRs and correlation coefficient of α2A-AR mRNA absorbance in brain tissue r was - 0. 509 (P = 0.031), and the correlation coefficient of α2A-AR protein-expression volume fraction in brain tissue r was - 0. 473 (P = 0. 047). Conelusions Regulation of blood pressure during acute ICH may have certain correlation with the up-expressions of α2A-AR in brain tissue and α1A-AR in renal tissue.

Objective To explore related factors affecting bone mineral density (BMD) and osteoporosis (OP) in patients with type 2 diabetes mellitus (T2DM). Methods Dual-energy X-ray absorptiometry was used to measure BMD of the femoral neck and the lumbar vertebrae in 220 patients with T2DM. All the patients were divided into three groups:normal bone mass group, decreased bone mass group and OP group according to the value of BMD. The clinical data and biochemical indicators were compared and analyzed between these groups, and the influencing factors of T2DM and OP were explored. Results Compared with normal bone mass group and decreased bone mass group, there were more older patients, longer course of T2DM, lower BMI and high density lipoprotein cholesterol (HDL-C), and higher glycated hemoglobin (HbA1c) level in OP group. There were significantly higher age, longer course of T2DM, higher level of HbA1c, and lower levels of BMI, HDL-C in decreased bone mass group than those of normal bone mass group (P＜0.05). There were no significant differences in waist-to-hip ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP), postmenopausal women (PMW) ratio, fasting plasma glucose (FPG), 2-h postprandial blood glucose (2hPG), blood phosphorus, calcium, total cholesterol (TC), three acyl glycerin (TG) and low-density lipoprotein cholesterol (LDL-C) between three groups. The risk factors for T2DM combined with OP were older, female, long duration of T2DM, higher levels of FPG, 2hPG and HbA1c. Conclusion Older and female T2DM patients were high-risk group of OP. The treatment plan should be timely adjusted by regularly monitoring indexes of blood glucose and HbA1c.

Objective To investigate the effect of ?-lipoic acid on the expression levels of intercellular adhesion molecule-1 (ICAM-1) in human umbilical vein endothelial cells under high glucose concentration. Methods Human umbilical vein endothelial cells (ECV304) were randomized into control (NG) group,high glucose (HG) group and ?-lipoic acid group. Cells in the 3 groups were incubated for 48h with 5.5mmol/L glucose,30mmol/L glucose,30mmol/L glucose + ?-lipoic acid in a series of concentrations (50,100,200?mol/L),respectively. The activity of superoxide dismutase (SOD) in the supernate was determined by the method of xanthine oxidase,and the content of malondialdehyde (MDA) was measured with thiobarbituric acid as the substrate. The level of ICAM-1 in the supernate was determined by enzyme-linked immunosorbent assay (ELISA). The expressive levels of ICAM-1 mRNA were determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results Compared with the control group,the activity of SOD declined significantly and the contents of MDA and ICAM-1 increased in umbilical vein endothelial cells in HG group (P

OBJECTIVE:To screen antioxidant active components of Schisandra chinensis. METHODS:The orthogonal test was adopted to optimize extraction technology using DPPH free radical scavenging activity(IC50)as index and ethanol volume frac-tion,material-liquid ratio and extraction time as factors,and the verification test were made. The fractions(SC-0,SC-10,SC-30, SC-50,SC-70,SC-95) were made by extracting and purifying S. chinensis with macroporous resin with water and 10%,30%, 50%,70%and 95%ethanol. With IC50 and total antioxidant capacity(determined by ABTS method)as indexes(vitamin C as pos-itive control),the antioxidant active components of S. chinensis were optimized. The contents of 5 kinds of lignan in different posi-tions of S. chinensis were determined by HPLC. RESULTS:The optimal extraction condition of S. chinensis was as follows as 60% ethanol,material-liquid ratio of 1∶14,extracting for 2.0 h. The average IC50 of DPPH free radical scavenging activity was 23.81 mg/ml(RSD=0.52%,n=3)in verification test. SC-0 did not have antioxidant abilities. DPPH free radical scavenging activi-ty of those components (ie. the IC50 value from low to high) were in the following order of positive control>SC-50>SC-30>SC-95>SC-70>SC-10;total antioxidant ability of them were in the following order of SC-50>positive control>SC-30>SC-70>SC-95>SC-10;the contents of 5 types of lignan in different components were in the following order of SC-70>SC-50>SC-95>SC-30. CONCLUSIONS:The antioxidant active component of S. chinensis is 50%ethanol eluate.

Objective:To investigate the effects of forced-air warming blankets combined with conventional warming strategies on the quality of postoperative recovery and cognitive recovery in elderly patients undergoing laparoscopic radical resection of colorectal cancer.Methods:This was a prospective, randomized, controlled trial.A total of 70 patients aged 65-75 years, who were classified as American Society of Anesthesiologists(ASA)grade-Ⅱ or Ⅲ, undergoing the laparoscopic radical resection of colorectal cancer under general anesthesia, were enrolled.Patients were randomly divided into two groups: the forced-air warming group(group FAW, n=35)and the conventional warming group(group CW, n=35). The inadvertent perioperative hypothermia(IPH), postoperative shivering, postoperative agitation, anesthesia recovery time and other postoperative complications were compared between the two groups.The post-operative quality of recovery scale(PQRS)was used to evaluate the quality of postoperative recovery and the recovery of cognitive function before and 1, 3, and 7 days after operation.Results:As compared with the group CW, the group FAW showed that the incidences of IPH, postoperative shivering and agitation were decreased(5.7% vs.22.8%, 2.8% vs.28.6%, 5.7% vs.31.4%, χ2=4.200, 10.057 and 7.652, P=0.042, 0.003 and 0.006), and the satisfaction degree of patients was increased at 48 hours after operation( P<0.01). The postoperative wake-up time was prolonged in the group CW as compared with the group FAW( P<0.01). Compared with the group CW, the proportion of patients with excellent overall recovery quality was increased in the group FAW 1 day after surgery( P<0.05). There was no significant difference in general recovery quality and cognitive recovery between the two groups at 3 and 7 days after operation. Conclusions:For elderly patients undergoing laparoscopic radical resection of colorectal cancer, the forced-air warming blanket combined with conventional warming strategies is more helpful to decrease the incidence of IPH, reduce postoperative shivering and improve the overall recovery quality at 1 day after operation, but no significant effect on postoperative recovery of cognitive function is found.

The modified early warning score (MEWS), as a rapid assessment and early warning scoring tool, has been widely used in patients in China, which can help nurses to identify potentially critical patients early, but not in all clinical fields. Through the retrieval of the relevant literature of the clinical application of the MEWS in Wanfang Medical Database from 2011 to 2018, the SWOT analysis was used in this paper [strength (S), weakness (W), opportunities (O) and threats (T)] methods, to systematically analyze the advantages, problems existence, implementation opportunities and challenges in the clinical application of the MEWS in our country. The purpose of this study was to obtain the best cut-off value of MEWS in different diseases and to formulate standard early-warning intervention measures for MEWS, which may provide reference for clinical workers to carry out relevant research.
