Effects of six kinds of Chinese herb extracts, including Folium Crataegi extract, Herba Epimedii extract, Folium Acanthopanacis Senticosi extract, Trifolium pratense L. extract, Folium Ginkgo extract and Radix Puerariae extract, on the activities of CYP450 isozymes (CYP1A2, CYP2C, CYP2E1, CYP2D, CYP3A) in rat hepatic microsomals were studied by using a UPLC-MS/MS (MRM) and cocktail probe substrates method. The results showed that effects of six kinds of Chinese herb extracts on each CYP450 isozyme activity were inhibitory. The IC50 of Folium Crataegi extract for the inhibition of rat microsomal CYP2D activity was only for 4.04 microg x mL(-1), which showed the highest inhibition; Trifolium pratense L. extract had strong inhibitory action to CYP2D, the IC50 value was 5.73 microg x mL(-1); Folium Crataegi extract also had strong inhibitory action on CYP2E1, the IC50 value was 10.91 microg x mL(-1). Furthermore, the IC50 of Folium Ginkgo extract for the inhibition of rat microsomal CYP3A, 2D, 2E1 activities were 45.12, 35.45 and 22.41 microg x mL(-1), respectively, and the IC50 of Folium Acanthopanacis Senticosi extract on the inhibition of rat microsomal CYP2E1 activity was 32.89 microg x mL(-1). In addition, mechanism of inhibition experimental results showed that the inhibiting abilities of Folium Crataegi extract and Radix Puerariae extract on each CYP450 isozyme increased with the increasing of the preincubation time, therefore, the inhibitory effects were a mechanism-based inhibition.

Objective To investigate the effect of proliferation,apoptosis and cell cycle of 3-MA on rat endothelial progenitor cells. Methods Bone marrow-derived mononuclear cells were isolated from rat bone marrow by ficoll. There were five groups. The control group and four 3-MA concentration groups: 1. 25 mmol/L,2. 5 mmol/L,5 mmol/L, 10 mmol/L. MTT was used to measure the proliferation of endothelial progenitor cells. Flow cytometry ( FCM) was used to detect cell apoptosis and cell cycle. Results (1)5 mmol/L 3-MA promotes proliferation of endothelial progenitor cells, while 10 mmol/L 3-MA inhibits the proliferation of endothelial progenitor cells (P ＜ 0. 05). (2) 10 mmol/L 3-MA promotes apoptosis of endothelial progenitor cells, compared with the control, the difference was significant ( P ＜ 0. 05 ). (3) 3-MA at the concentration of 5 mmol/L reduces cells at G0/G1 phase and increases S and G2/M phase cells; 10 mmol/L 3-MA induces endothelial progenitor cells blockade at S phase, G2/M phase cells decreased, compared with the control, the difference was significant (P ＜ 0. 05). Conclusions 5 mmol/L 3-MA promotes the proliferation of endothelial progenitor cells. 10 mmol/L 3-MA inhibits the proliferation and promotes apoptosis of endothelial progenitor cells.

Objective To discuss the surgical and interventional treatment of vascular injuries. Methods Clinical data of 85 patients with vascular injuries were retrospectively studied by grouping. Location of injury included jugular vein, vertebral artery, main extremity vessels and superior mesenteric artery. There were 25 patients with traffic injury and 60 with stah injury, of whom 62 patients underwent surgical operation (vascular grafting were performed in 37 and vascular repair in 25) and 23 received in-tervention therapy. Results There were one death and one amputation. Fifty-eight patients were fol-lowed up, which showed that all patients had good vascular patency. Conclusions Prompt and correct diagnosis is very important for treatment of vascular injury. Interventional treatment had merits of minor trauma, short operation duration, simple manipulation and quick postoperative recovery. Surgical opera-tion and endovascular intervention can be used together in treating vascular injury.

Objective To discuss the methods and the efficacy of interventional treatment of vascular injuries. Methods From January 2006 to March 2008, interventional therapy was performed in 13 cases of vascular injuries including injuries of internal jugular vein, subclavical artery, axillary artery,inferior vena cave, abdominal aorta, superior mesenteric artery, arteria iliaca, vena iliaca and femoral artery.Types of these injuries included arteriovenous fistula in 3, vascular rupture complicating haematoma in 4,pseudoaneurysm in 3 and arterial stenosis ensuing from injury repair in 3. Covered stent-grafts were used in 9 cases (10 stent-graft), mesh stem in 1, sealed with balloon in 2 and introcoil embolism in 1.Result Interventional procedure was successful in all these 13 cases, there was no mortality nor severe complications. Small amount of endoleak developed in thoracic aorta pseudoaneurysm and contrast leaked from internal jugular vein in left subclavical arteriovenous fistula after stent-graft insertion, these were healedconservatively. Twelve cases were followed up from 1 to 26 months. Hemoptysis occurred in patient with thoracic aorta pseudoaneurysm 12 months after intervention but without abnormality in CTA. There were no stem break, shift, deformation or stennsis and there were no recurrence of primary disease.Conclusion Interventional therapy is of less invasion, short performation duration, simple manipulation and quick postoperative recovery for vascular injuries.

Objective To analyze the clinical efficacy of AngioJet mechanical thrombus aspiration system for patients with acute pulmonary embolism (PE).Methods Clinical data of 28 cases of acute pulmonary embolism (PE) patients was retrospectively analyzed,8 cases (AngioJet group) were treated with AngioJet + CDT,20 cases were treated by pigtail catheter thrombolysis(CDT group)alone,the total amount of urokinase,thrombolytic time,related detection index and the occurrence of complications were compared between the two groups.Results The dosage of urokinase in the two groups was (72.5 ± 44.4) × 104U and (169.0 ± 59.3) × 104 U respectively,P ＜ 0.05.The catheter indwelling time was (1.0 ± 0.89) days and (2.65 ± 0.86) days respectively (P ＜ 0.05).There were no statistically significant differences in SBP,PaO2,SpO2 and D-dimer between the two groups before and after operation (P ＞ 0.05).Conclusion Both AngioJet and CDT are effective methods for the treatment of acute PE.The combination of the two methods can accelerate the improvement of clinical symptoms,reducing the dosage of thrombolytic drugs and the occurrence of surgery-related complications.

Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

With the acceleration of global urbanization, the intensity and coverage of artificial light at night (ALAN) are increasing, and its service duration is obviously prolonged. ALAN exposure is not only related to the occurrence and development of cardiovascular, metabolic, sleep, myopia, and mental diseases, but also may induce cancer. Previous studies have focused on the health effects of outdoor ALAN, but people spend more than 80% of their lives indoors, hence it is of great significance to understand the relationship between indoor ALAN and population health to create a healthy indoor environment and protect the health of the population.

Objective:To follow up and observe the intellectual development of school children aged 8 to 10 in Baicheng County, Xinjiang Uygur Autonomous Region, which was a severe iodine deficiency disorders region in history, before and after effective control of the disease, in order to evaluate the impact of iodine supplementation on protection of children's intellectual development and provide a theoretical basis for scientific supplements of iodine.Methods:From 1989 to 2018, Combined Raven's Test for Rural in China (CRT-RC) was used to observe the intellectual development status of 660 Uyghur school children aged 8 to 10 in Baicheng County in 1989, 2002, 2006, 2012 and 2018, respectively. Children's intelligence quotient (IQ) was calculated using CRT-RC's 1987 normal sample of rural children in the same age group; the data of average iodized salt coverage rate (C-IS) and childhood goiter rate (GR) from multiple local surveys and the median urinary iodine (MUIC) of children were collected, combined with the "Criteria for Elimination of Iodine Deficiency Disorders" (GB 16006-2008) and the United Nations International Children's Emergency Fund (UNICEF) recommended standards, the status of iodine deficiency during children's growth (IDG) was divided into complete exposure to iodine deficiency, no exposure, and semi-exposed. The Flynn effect (FE) gain was calculated using norm samples of children aged 8 to 10 in 1987, 1996 and 2006 of CRT-RC, and the differences in children's intellectual development after FE correction before and after IDG reached the standard were compared.Results:The IQ of children were (81.67 ± 14.13), (83.26 ± 14.05), (89.68 ± 13.58), (98.50 ± 14.33) and (103.23 ± 15.25) points in Baicheng County in 1989, 2002, 2006, 2012 and 2018, respectively, the difference between different years was statistically significant ( F = 58.357, P < 0.01). The three indicators of C-IS, GR, and MUIC didn't meet the standards during the IDG evaluation period in the 1989, 2002, and 2006 groups, which were the complete exposure to iodine deficiency; in the 2012 group, only the MUIC met the standard, which was semi-exposed; in the 2018 group, three indicators all met the standard, which was no exposure. The FE gains of 1987 with 1996, 1996 with 2006 were 0.96 points/year and 0.74 points/year, respectively; after FE correction, the actual gains of IQ of 2002 and 2006 compared with 1989, 2012 and 2018 compared with 2006 were - 9.57, - 6.11, 4.38, and 4.67 points, respectively. Conclusions:In iodine deficiency areas, intermittent iodine supplementation (1989 - 2009) for children exposed to iodine deficiency during growth still cannot effectively protect children's intellectual development; continuous and effective iodine supplementation (2010 - 2018) with iodized salt as the core and covering children's growth period has obvious positive effects on protection of children's normal intellectual development. In the future, we will continue to observe the influence of IDG full-cycle suitable iodine nutrition on children's intellectual development.
