Objective To explore how the different intervention measures affect the outcome of central venous catheter-related thrombosis (CRT) in children. Methods A retrospective analysis was carried out to collect the clinical data of patients with CRT from the nursing management system of the Children′s Hospital Affiliated to Zhejiang University School of Medicine which reported by each nursing unit from January 1,2015 to December 31,2015. Results Totally 108 cases were included (72 boys and 36 girls), median age of 24.5 months (ranged from 1 month to 14 years old). Nearly 42.59% (46/108) patients suffered from neurological diseases. Nearly 55.56%(60/108) CRT was detected in the first week after catheterization. Once CRT conformed, there were four kinds clinical intervention options applied. Intervention 1: thrombolytic therapy with urokinase combined anticoagulation with nadroparin calcium. Intervention 2: anticoagulant therapy only. Intervention 3: thrombolytic therapy alone. Intervention 4: no medications. The differences of effective between the four kinds of intervention were statistically significant (χ2=13.380, P=0.004). The single-factor regression analysis was done to each relevant factor. Finally the multivariate regression analysis showed four factors had impacts upon the results. The factors were as follows:gender (OR=10.400, 95%CI 1.879-57.563, P=0.007);interval (OR=1.107, 95%CI 1.035-1.184, P = 0.003), size of thrombus(OR = 1.562,95%CI 1.033-2.362,P=0.035; Intervention 2 (OR =11.757, 95% CI 2.254- 61.327, P = 0.003), intervention 4 (OR = 35.397, 95% CI 3.493-358.760, P =0.003). Conclusions The earlier and small size thrombus is more soluble. Thrombolytic therapy or combined anticoagulation is more effective. It is recommended that if no contraindications presents, thrombolytic combined with anticoagulant therapy should start early standardized treatment.

Objective To investigate the incidence of retinopathy of prematurity (ROP) in our hospital and to explore the risk factors of ROP.Methods Premature infants hospitalized in our hospital in January 2010 to December 2012 were chosen,and the gestational ages were less than 36 gestational weeks,birth weights were under 2 500 g.All the cases underwent ROP screening at two weeks after birth,and then they received regular follow-up.Children with systemic conditions and oxygen to the mother during pregnancy,oxygen,preeclampsia,placental abruption,and other factors were analyzed.Results Two hundred and fifty-five cases completed the retinal screening,terminated follow-up after the peripheral retinal neovascularization or disease degradation.We found ROP in 16 cases (26 eyes),ROP prevalence rate was 6.3％ (5.1％),including phase Ⅰ 12 cases,phase Ⅱ3 cases,phase Ⅲ 1 case.Gestational age,birth weight,inhale oxygen time,oxygen concentration,mechanical ventilation were associated with ROP (P ＜ 0.05).Mother oxygen during pregnancy,preeclampsia,placental abruption had nothing to do with the incidence of ROP.Conclusion Premature birth,high concentrations of oxygen,mechanical ventilation are major risk factors of ROP.Timely screening of ROP and found early to do the retinal laser photocoagulation in premature,can control the disease,reduce the blindness rate of premature infants.

Objective To assess the safety and efficacy of stent-assisted coil embolization for acutely ruptured wide-necked intracranial aneurysms. Methods We retrospectively reviewed 192 wide-necked intracranial aneurysms in 178 patients. The efficacy and peri-procedure complications of stent-assisted embolization were compared between rup?ture aneurysms and unrupture aneurysms. Results Stent was successfully implanted in 78 rupture aneurysms and 114 un?rupture aneurysms. There was statistically significant difference between rupture aneurysms and unrupture aneurysms groups in rate of poor prognosis on discharge ( 23.1%vs. 5%,χ2=12.726, P<0.001) but not in the peri-procedure compli?cations rate (14.1%vs. 6.1%,χ2=3.456,P>0.05)nor in the rate of mortality and permanent disability (8.9%vs. 6.1%,χ2=0.475, P>0.05). Angiograms at 14.7 months of follow-up did not reveal any significant difference between rupture aneu?rysms and unrupture aneurysms groups in aneurysm complete occlusion (74.1%vs. 70.6%,χ2=0.197,P>0.05), recana?lization (10.3%vs. 9.4%,χ2=0.034,P>0.05)and in-stent stenosis (3.4%vs. 4.7%,χ2=0.136,P>0.05). Conclusion Stent-assisted coil embolization for acutely rupture wide-necked intracranial aneurysms can prevent recurrence effective?ly and can achieve high complete occlusion rate in long term follow-up. However, its procedure related complications and mortality is higher in rupture aneurysms than in unrupture aneurysms, which indicates that a caution is needed to conduct stent-assisted coil embolization in rupture aneurysms.

Objective To evaluate the value of TruviewTM EVO2 optical laryngoscope for emergency endotracheal intubation in the clinical application.Methods Forty-four patients in need for emergency endotracheal intubation were randomly (random number) divided into two groups:the observation group (TruviewTM EVO2 optical laryngoscope for tracheal intubation,n =22) and the control group (ordinary laryngoscope for tracheal intubation,n =22).Parameters recordered included C/L (Cormack-Lehane)grade,the time taken for successful intubation,tracheal intubation times,lowerest SpO2 during the intubation and the incidences of complications after intubation.IDS (intubation difficulty scale) scores were calculated and the total effective rates were compared.Results The data showed that there were no significant differences in the duration of the successful endotracheal intubation attempts between the two groups,respectively (24.04 ±6.56) s and (21.97 ±8.92) s,P ＞0.05.The C/L grade with the observation group was 10∶ 9∶ 3∶0 (Ⅰ ∶ Ⅱ ∶ Ⅲ∶ Ⅳ),which was significantly better than that with the control group (3∶ 7∶ 9∶ 3,P ＜0.01).The tracheal intubation times of the observation group was 17∶ 5∶0 (one time∶ two times∶ three times),which was significantly better than that of the control group (9∶ 8∶ 5,P ＜0.01).The minimum of SpO2 in the observation group (97.31 ± 1.64)％ was significantly higher than that in the control group (92.03 ± 5.39)％,(P ＜ 0.01).The incidence of complications after intubation was lower in the observation group.The IDS score in the observation group (0.68 ± 0.38) was much lower than those in the control group (2.54 ± 1.49),(P ＜ 0.01).In addition,the total effective rate of the observation group (86.36％) was significantly higer than that in the control group (45.45％),(P ＜0.01).Conclusions Using optical laryngoscope for emergency endotracheal intubation could facilitate the glottis exposure and reduce C/L grade effectively.It could lead to lower the incidence of complications and increase the success rate of tracheal intubation.
