Objective To observe the clinical efficacy of butylphthalide soft capsules for treatment of acute cerebral infarction and its effect on the neurological function and inflammatory reaction of patients.Methods A total of 100 patients with acute cerebral infarction in the First Hospital of Zhangjiakou City and the Third Hospital Affiliated to Hebei North University from January 2016 to October 2016 were selected and divided into control group (n =50) and treatment group (n =50) according to the treatment protocols.The patients in the control group were given anti-platelet aggregation,statins,and other routine treatment;based on this,the patients in treatment group were orally administrated with butylphthalide soft capsules.The elbow venous blood of patients in the two groups was collected and the C reactive protein(CRP),interleukin-6 (IL-6) levels,the platelet aggregation rate were detected.The change of National Institute of Health stroke scale(NIHSS) score of patients after four weeks treatment was compared between the two groups.The recovery of neurological function of patients in the two groups was evaluated by modified Rankin grading after three months treatment.Results There was no statistic difference in the CRP,IL-6 levels and platelet aggregation rate before treatment between the two groups (P ＞ 0.05).The CRP,IL-6 levels and platelet aggregation rate of patients in the two groups after one week treatment were significantly lower than those before treatment (P ＜ 0.05);and the CRP,IL-6 levels and platelet aggregation rate of patients in the treatment group were significantly lower than those in the control group after one week treatment (P ＜ 0.05).The NIHSS score of patients in the treatment group was significantly lower than that in the control group after four weeks treatment (P ＜ 0.05);the Rankin score of patients in the treatment group was significantly lower than that in the control group after three months treatment (P ＜ 0.05).The total effective rate of patients in the treatment group was significantly higher than that in the control group (x2 =13.22,P ＜ 0.05).Conclusion Butylphthalide soft capsules can significantly reduce the inflammatory reaction in patients with acute cerebral infarction,improve and recover the neurologic impairment;and its curative effect is remarkable.

OBJECTIVE:To investigate the effects of low molecular weight heparin calcium and rivaroxaban combined with atorvastatin on related indexes in patients with acute pulmonary embolism(APE). METHODS:The data of 72 APE patients were analyzed retrospectively. According to treatment plan,the patients were divided into group A(21 cases),group B(26 cases)and group C(25 cases). Group A was treated with intramuscular injection of Low molecular heparin calcium injection immediately after admission;2 days later,they were given Warfarin sodium tablets;7 days later,Low molecular heparin calcium injection was stopped while warfarin was still administrated,lasting for 3-6 months. Group B was given Low molecular heparin injection(same usage and dose as group A);2 days later,they were additionally treated with Rivaroxaban tablets;7 days later,Low molecular heparin calcium injection was stopped while rivaroxaban was still administrated,lasting for 3-6 months. Based on the treatment in group B,group C was treated with Atorvastatin calcium tablets 20 mg orally,once a day in the evening,lasting for 3-6 months. The time of dyspnea,chest pain and cyanosis disappearance were observed in 3 groups as well as the levels of HR,pa(O2),pa(CO2), CRP,D-dimer,TNF-α,IL-1,IL-6,ET-1 and NO before and after treatment. The occurrence of clinical outcome events and ADR were also observed. RESULTS:The time of dyspnea,chest pain and cyanosis disappearance in group A were longer than group B, and the group B was longer than the group A,with statistical significance(P<0.05). Before treatment,there was no statistical sig-nificance in the levels of HR,pa(O2),pa(CO2),CRP,IL-1,IL-6,TNF-α,D-D,ET-1 and NO among 3 groups(P>0.05). After treatment ,HR of 3 groups were all lower than before ,and they showed group Agroup B>group C,with statistical signif-icance(P<0.05). After treatment,CRP,IL-1,IL-6,TNF-α and D-D levels in 3 groups were significantly lower than before,and they showed group C>group A and group B,with statistical significance (P<0.05);but there was no statistical significance be-tween group A and B(P>0.05). ET-1 levels in 3 groups were significantly lower than before,and the levels showed group group group B>group A,with statistical significance (P<0.05). The incidence of clinical outcome events in group A was significantly higher than group C, the incidence of ADR in group B was significantly lower than that group A,with statistical significance(P<0.05). CONCLUSIONS:Low molecular weight heparin calcium and rivaroxaban combined with atorvastatin can significantly im-prove clinical symptoms and blood gas indexes,relieve vascular endothelial damage,reduce the levels of inflammatory cytokines and improve the prognosis of patients with APE,without increasing the incidence of ADR.

Objective To investigate the effect of ultrasound debridement combined with vacuum sealing drainage on the treatment of diabetic foot ulcer and the potential mechanism. Methods Eighty-one patients with diabetic ulcer were randomly divided into two groups:ultrasound debridement combined with vacuum sealing drain-age as the experimental group,routine debridement combined with vacuum sealing drainage as the control group. The clinical curative effect,the reduction rate of the wound,the rate of blastocyst and the rate of bacterial clear-ance and blood flow were detected.Results The clinical curative effect in the experimental group was significantly better than that in the control group(P < 0.05). The rates of wound reduction and granulation were significantly higher than those in the control group(P<0.05).After 14-day treatment,the blood perfusion in the experimental group was significantly higher than that in the control group(P<0.05),and the expression of HIF-1α and VEGF in the ulcer tissue was significantly higher than that in the control group(P<0.05).Conclusions Ultrasound de-bridement combined with vacuum sealing drainage can improve the clinical efficacy,wound reduction rate,granu-lation coverage rate and bacterial clearance rate,and increase ulcer tissue blood flow. The potential mechanism is related with the increases of HIF-1α and VEGF in ulcer tissue.

Objective: Endometrial cancer (EC) is a common gynecological malignant tumor. CircRNAs play crucial roles in cancer progression and metastasis. However, the biological functions of circRNAs in EC remain largely unknown. Methods: CircSMAD2, miR-1277-5p, MFGE8 and relative maker protein expression in EC tissues or cell lines were analyzed by quantitative real-time polymerase chain reaction and Western blot. In vitro and in vivo functional assays, including EDU, CCK8, colony formation, transwell, tube formation and tumor xenograft assays, were conduct to explore the effects of circSMAD2 on EC. Mechanism assays were conducted to confirm the binding between miR-1277-5p and circSMAD2 or MFGE8 expression. Results: Upregulation of circSMAD2 was uncovered in both EC tissues and cell lines. Functionally, silencing of circSMAD2 apparently inhibited the proliferation, migration, invasion and angiogenesis of EC cell lines in vitro. Mechanistically, circSMAD2 sponged miR-1277-5p to upregulate MFGE8 expression. The decrease of miR-1277-5p and increase of MFGE8 were observed both in EC tissues and cell lines. Then MFGE8 knockdown or miR-1277-5p upregulation suppressed EC cell oncogenic biological behavior. Rescue experiments showed that miR-1277-5p mimics countervailed the anticancer effects of circSMAD2 silencing on EC. Besides that, MFGE8 overexpression also attenuated the inhibitory action of miR-1277-5p mimic in EC. Moreover, knockdown of circSMAD2 inhibited EC growth in vivo. Conclusion CircSMAD2 functions as an oncogene in promoting the progression of EC through miR-1277-5p/MFGE8 axis.

【Objective】 To investigate the risk factors of vasovagal reactions(VVR) related to plasma donation, so as to put forward clinical suggestions for early identification and accurate intervention of high-risk groups to ensure the safety of plasma donation. 【Methods】 The demographic characteristics(i.e. gender, age, weight) and records of plasma donors(donation history, pulse before plasma donation, duration of collection, etc.) were collected from July to December 2019 in a region of Sichuan. Based on logistic regression analysis, the correlation between these factors and the risk of VVR was explored. 【Results】 The information of 69 172 donors was collected, and the incidence of VVR was 7.04‰. The risk of VVR was reduced by 99% in the group with plasma collection duration less than 30 minutes compared with the group with plasma collection duration more than 50 minutes(OR, 0.01; 95% CI, 0.00~0.01; P<0.001). The risk of male group was 94 % lower than that of female group(OR, 0.06; 95% CI, 0.04~0.10; P<0.001). Compared with the 45~50 kg group, the risk of weight greater than 80 kg group decreased by 80%(OR, 0.20; 95% CI, 0.09~0.42; P<0.001). The risk of repeated donation group was 34 % lower than that of the first time donation group(OR, 0.66; 95% CI, 0.47~0.91; P<0.001). The risk of VVR in the group with pulse greater than 90 bpm before plasma donation was 2.43 times that in the 60~69 bmp group(OR, 2.43; 95% CI, 1.75~3.36; P<0.001). 【Conclusion】 Duration of plasma collection, gender, weight, frequency of plasma donation, pulse before plasma donation and donor status are independent risk factors for plasma donation-related VVR. Among them, plasma collection duration, gender and weight were the main independent risk factors for plasma donation-related VVR. For donors with plasma collection duration more than 50 minutes, female and low weight, higher risk of VVR was presented and more preventive intervention should be given.
