Objective: To investigate the chemical constituents in the EtOAc fraction of the EtOH extract of Duchesnea indica Andr. Focke. Methods: Extraction was done with 95% EtOH. EtOAc fraction of the EtOH extract was isolated and purified by column chromatography using silica gel,RP-C18,Sephadex LH-20 and HPLC. The structures of the compounds were identified by their physico-chemical properties and spectral analysis. Results: Thirteen compounds were obtained from the EtOAc fraction of Duchesnea indica Andr. Focke and they were identified as euscaphic acid(1),arjunic acid(2),p-hydroxy cinnamic acid (3),apigenin(4),kaempferol(5),2α-hydroxy ursolic acid(6),2α-hydroxy oleanolic acid(7),tomentic acid(8),kaii-ichigeside F1 (9), potengriffioside A (10), rosamultin (11), kaempferol-3-O-β-D-glucoside (12), and isoquercitrin (13). Conclusion: The compounds 2-5,10, and 12 have been isolated from the genus of Duchesnea for the first time.

Objective: To assess the effect and safety of Qingwei Zhitong Pill(QZP) in treating duodenal ulcer with fire stagnation syndrome. Methods: A randomized, double-blinded double-mimic controlled trial was adopted. Sixty patients were treated with QZP, 60 with Sifang Wei tablet(SWT) and 40 served as the open treatment group. Results: In QZP group, the markedly effective rate evaluated by gastroscopy was 48.33%and the total effective rate was 76.67%; the markedly effective rate in relieving TCM syndromes was 73.33%and the total effective rate was 88.33%, the differences between the treatment group and the control group were significant (P

Objective:To analyze the effect of insulin aspart on the islet cell secretion function, ultrasound imaging indicators and maternal and infant outcome in patients with gestational diabetes mellitus (GDM).Methods:The clinical data of 120 patients with GDM in Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University from February 2017 to July 2019 were retrospectively analyzed. Among them, 60 cases were treated with insulin aspart (observation group) and 60 cases were treated with biosynthetic human insulin (control group). The efficacy indexes, ultrasound imaging indexes and maternal and infant outcome were compared.Results:The 2 h postprandial blood glucose (2 h PBG) after breakfast on the third and fifth day of treatment in observation group was significantly lower than that in control group: (6.85 ± 0.87) mmol/L vs. (7.47 ± 1.35) mmol/L and (6.24 ± 0.59) mmol/L vs. (6.60 ± 0.87) mmol/L, and there was statistical difference ( P<0.01); there was no statistical difference in 2 h PBG after breakfast on the first day of treatment and after lunch and dinner on the first, third and fifth day of treatment between 2 groups ( P>0.05). The homeostasis model assessment-insulin resistance index (HOMA-IR) after treatment in observation group was significantly lower than that in control group (2.57 ± 0.25 vs. 3.00 ± 0.35), the homeostasis model assessment- β cell function index (HOMA-β) was significantly higher than that in control group (72.45 ± 12.33 vs. 63.66 ± 10.72), and there were statistical differences ( P<0.01). There were no statistical differences in pre-lunch blood glucose, pre-lunch initial insulin amount, pre-lunch final insulin amount and blood glucose target time between 2 groups ( P>0.05); the incidence of pre-meal hypoglycemia in observation group was significantly lower than that in control group: 8.33% (5/60) vs. 23.33% (14/60), and there was statistical difference ( P<0.05). The umbilical artery and renal artery resistance index (RI), maximum systolic blood flow velocity and end-diastolic blood flow velocity ratio (S/D) after treatment in observation group were significantly lower than those in control group (RI: 0.49 ± 0.16 vs. 0.59 ± 0.15 and 0.69 ± 0.17 vs. 0.76 ± 0.12; S/D: 2.09 ± 0.22 vs. 2.38 ± 0.26 and 5.17 ± 0.45 vs. 5.77 ± 0.63), and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in gestational age, delivery mode, neonatal body weight and the incidences of macrosomia, neonatal hypoglycemia and neonatal referral between 2 groups ( P>0.05). Conclusions:Insulin aspart can significantly improve the islet cell secretion function and ultrasound imaging indexes in the treatment of GDM, and can reduce the risk of pre-meal hypoglycemia, but the effect on maternal and infant outcome remains to be explored.

E-selectin is an inducible adhesion molecule,and it is correlated with various molecules during cerebral ischemia/reperfusion injury.This article mainly reviews the relationship between E-selectin and intracellular adhesion molecule-1,tumor necrosis factor-?,NF-kB,leucocyte function-associated antigen-1 in cerebral ischemia/reperfusion injury,so as to provide assistance for E-selectin in the prevention,diagnosis and treatment of ischemic cerebrovascular disease.

OBJECTIVE:To study the anti-inflammation effects of cacumen biotae water decoction on mice with auricle and ab-dominal inflammation. METHODS:Mice were randomized into a normal control group,a model group,a positive control group (0.25 g/L aspirin)and cacumen biotae high-dose,medium-dose and low-dose [1,0.5 and 0.25 g(medicinal materials)/L] groups, respectively marked as groups A,B,C,D,E and F,with 10 mice in each group. The mice were given drugs ig for 5 consecutive days. The models of auricle and abdominal inflammation were established for all groups except the normal control group. The con-tents of tumor necrosis factor α(TNF-α)and interleukin 1(IL-1)in the serum of mice with auricle inflammation were determined, and the swelling degree and swelling rate were calculated. The contents of TNF-α,IL-1 and acid-sensing ion channels 1a(ASIC1a) in the liver tissues of mice with abdominal inflammation and the concentration of proteins in the peritoneal lavage fluid(ΔA)there-of were detected. RESULTS:For mouse models of auricle inflammation,the contents of TNF-α and IL-1 in serum in group B were higher than in group A;the swelling degree and swelling rate and the contents of TNF-α and IL-1 in groups C,D,E and F were lower than in group B,and those of group E and F were higher than in group C. There were statistical differences(P<0.05). For mouse models of abdominal inflammation,the contents of TNF-α,IL-1 and ASIC1a in liver tissues and ΔA in group B were higher than in group A;the contents of TNF-α,IL-1 and ASIC1a as well as ΔA in groups C,D,E and F were lower than in group B. There were statistical differences(P<0.05). CONCLUSIONS:Cacumen biotae water decoction has anti-effect on acute auricle and abdominal inflammation by a mechanism which may be related to decreasing TNF-α,IL-1 and ASIC1a.
