OBJECTIVE:To investigate clinical efficacy of intravenous drip of alprostadil combined with acupuncture in the treatment of diabetic foot ulcer and its effects on inflammatory factors levels and wound microvascular density. METHODS:A total of 72 patients with diabetic foot ulcer in our hospital during May 2014 to Sept. 2015 were divided into observation group and con-trol group according to random number table,with 36 cases in each group. Control group was given Alprostadil injection 10μg add-ed into 250 mL 0.9% Sodium chloride injection intravenously,qd,on the basis of routine treatment as insulin. Observation group was additionally given acupuncture therapy (Sanyinjiao,Zusanli,Fenglong,Yanglingquan,Yinlingquan and other acupuncture points),qd,on the basis of control group. Treatment courses of 2 groups lasted for 3 weeks. Clinical efficacy,wound healing time,fasting blood glucose,urine microalbumin,inflammatory factors,wound microvascular density as well as the occurrence of ADR were compared between 2 groups. RESULTS:The total response rate of observation group(91.67%)was significantly higher than that of control group(72.22%),and wound healing time was significantly shorter than control group,with statistical signifi-cance(P<0.05). Before treatment,there was no statistical significance in fasting blood glucose,urine microalbumin and inflamma-tory factors between 2 groups (P>0.05). After treatment,above indexes of 2 groups were significantly lower than before,and urine microalbumin and inflammatory factors of the observation group was significantly lower than the control group,with statisti-cal significance (P<0.05). 14,21 d after treatment,wound microvessel density of observation group was significantly higher those of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Intrave-nous drip of Alprostadil combined with acupuncture can boost angiogenesis through mitigating inflammatory reactions,thus shorten the time of wound healing and enhance therapeutic efficacy.

[ ABSTRACT] AIM:To investigate the role of ATP-sensitive potassium ( KATP ) channels in the inhibitory effect of hydrogen sulfide ( H2 S) on high glucose ( HG)-induced inflammation mediated by necroptosis in H 9c2 cardiac cells. METHODS:The expression levels of receptor-interacting protein 3 ( RIP3; an indicator of necroptosis ) and cyclooxyge-nase-2 (COX-2) were determined by Western blot.The levels of interleukin-1β(IL-1β) and tumor necrosis factor-α( TNF-α) were detected by ELISA .RESULTS:After H9c2 cardiac cells were treated with 35 mmol/L glucose ( HG) for 24 h, the expression of RIP3 was significantly increased .Pre-treatment of the cells with 100 μmol/L diazoxide ( DZ; a KATP channel opener) or 400 μmol/L NaHS (a donor of H2S) for 30 min considerably blocked the up-regulation of RIP3 induced by HG.Moreover, pre-treatment of the cells with 100 μmol/L 5-hydroxydecanoic acid (5-HD; a KATP channel
blocker) attenuated the inhibitory effect of NaHS on HG-induced up-regulation of RIP3.On the other hand, co-treatment of the cells with 100μmol/L necrostatin-1 ( a specific inhibitor of necroptosis ) or pre-treatment of the cells with 100 μmol/L DZ or 400 μmol/L NaHS attenuated HG-induced inflammatory responses , evidenced by decreases in the expression of COX-2 and secretion levels of IL-1βand TNF-α.However , pre-treatment of the cells with 100 μmol/L 5-HD significantly attenuated the above anti-inflammatory effects of NaHS.CONCLUSION:KATP channels play an important role in the inhib-itory effect of H2 S on HG-induced inflammation mediated by necroptosis in H 9c2 cardiac cells.

OBJECTIVETo evaluate the safety and efficacy of the Amplatzer septal occluder for transcatheter closure in patients with secundum atrial septal defect (ASD II).

METHODSPatients with clinically confirmed ASD II were recommended for transcatheter closure of ASD II.

RESULTS30 ASD II patients (20 females) underwent transcatheter closure at a median age of 18.4 years (5-55 years). Both the stretched diameters of ASDs and the sizes of the devices were from 18 to 34 mm (25 +/- 7 mm). The successful placement rate was 100%. The rest shunt documented by color Doppler, was immediately after implantation in 40% of patients, in 9.9% after 24 hours, and in 3.3% trace at 3 months. No serious complications were observed. There was improvement in symptoms and in cardiac size. Septal motion abnormalities normalized in all patients after 3 months follow-up.

CONCLUSIONThe Amplatzer septal occluder is a safe and effective device for transcatheter closure of ASD II. Long-term follow-up is still required before widespread clinical use can be recommended.

【Objective】 To demonstrate the real incidence and clinical features of acute transfusion reactions (ATRs) and analyze its association with transfusion effectiveness. 【Methods】 The blood transfusion process of patients in the Hematology Department in our hospital from March 16, 2018 to March 16, 2019 was observed and followed up. The vital signs and clinical features were recorded, the clinical data and relevant laboratory examination results were collected, and the correlation between ATRs, clinical features and transfusion effectiveness was statistically analyzed. 【Results】 A total of 2500 transfusions were observed in the Hematology Department, out of which 138 patients developed 242 ATRs. The overall incidence of ATRs was 9.68% (95% CI, 8.52%~10.94%) and the incidence of ATRs during platelets transfusion was the highest. The clinical features of most ATRs were mild and no fatal consequences occurred. No significant difference was found in the association between transfusion effectiveness with ATRs in platelets and red blood cells transfusion (P>0.05). 【Conclusion】 None of the ATRs observed in this study resulted in serious consequences or had effect on the transfusion effectiveness. The characteristics presented in these reactions may provide certain references for clinical practice.
