Objective To investigate the prevention and nursing measures of chemotherapeutic phlebitis in hematonosis children.Methods 233 children with first-attack of hematonosis were admitted to our department from January 2010 to January 2012,among whom 80 cases appeared different degrees of chemotherapeutic phlebitis.The related factors of chemotherapeutic phlebitis were explained and the nursing measures were established.Results After effective nursing measures,the chemotherapeutic phlebitis were properly handled.Conclusions Correct selection of vascular puncture site,strict aseptic operation and implementation of relevant nursing measures can prevent the incidence of chemotherapeutic phlebitis,and local closure,using of patches and external application of scald ointment can be adopted to treat chemotherapeutic phlebitis.

Retrospectively from February, 2006 to June, 2009 the clinical characteristics of 14 misdiagnosed cases of insulinoma in the First Affiliated Hospital of Zhengzhou University were analysed. The rate of misdiagnosis was 38% ( 14/37). The rate of IRI/G≤0. 3 was 33%. Insulinoma has often been misdiagnosised when IRI/G≤0. 3. Hence a diagnosis of insulinoma can not be excluded with this IRI/G rate.

Objective To explore the methods, dosimetric features and short-term effects of partial breast irradiation carried out by three-dimensional external-beam irradiation (3DCPBI) assisted by active breathing control (ABC) . Methods Computed tomography (CT) simulation assisted by active breathing control (ABC) was carried out for each patient and intended to get CT images in condition of 75% deepest inspiration named moderate deep inspiration breath hold (mDIBH). The extent labeled by the silver slips located in the cavity was delineated as gross target volume (GTV) , GTV plus the margin of 15 mm was defined as planning target volume (PTV). 6 MV X-ray was selected as the radiation source and noncoplanar radiation with four three-dimensional conformal fields was used, the described dose was 34 Gy /10f/5d. The volume of GTV, PTV, the affected whole breast, and the percentage of PTV accounted for the affected whole breast , the percentages of PTV included by 100% , 95% and 90% isodose curve, the percentage of volume of the affected breast irradiated by 34. 0, 27. 2, 20. 4, 13. 6 and 6. 8 Gy , and Dmean,D5,V20 of the lungs and heart were calculated respectively. Acute radiation skin response was recorded and the cosmetic effect of the breast after radiotherapy were appraised, with the local tumor control and survival rate followed. Results The mean of volume ratio of PTV and affected whole breast was 14. 88% ; the mean of the volume covered by 90% isodose curve accounted for 92. 54% of the PTV; the volume irradiated by 34 Gy (100% of described dose) accounted for 17. 23% (mean) of the whole breast and 6. 8 Gy (20% of described dose) for 46. 11% , in other words, the volume covered by 20% of described dose was less than 50% of the whole breast. The Dmean, D5, V20 for the affected lateral lung were 1.97, 9. 25 Gy and 1. 58% , it was 0.20, 0. 87 Gy , and 0% for the unaffected lateral lung. The Dmean,D5, V20 for the heart was 0.65 Gy , 2. 82 Gy , and 0. 85%. Zero grade of acute radiation skin reaction was seen in 14 patients and gradel in 3 patients and there was not equal to or more than grade 2 of skin reaction for all the patients. Cosmetic effect were appeci-ated and satisfaction defined as excellent or good appearance of the irradiated breasts for all the patients. No recurrence of local tumor for all of the patients followed for one year. Therefore, the cosmetic result of 1 yr. follow - up was 100% and no recurence was found after 1 yr. follow - up. The 1-year tumor-free survival rate were all 100%. Conclusions For selected patients with early breast cancer after breast-conservative surgery, 3DCPBI assisted by ABC is feasible, however, the selection criteria for the patients, technique protocol and dose fractionation of 3DCPBI and its influence on late cosmetic effect, local tumor control and survival need to be continuously explored and observed in the future.

Objective: To evaluate the left ventricular systolic synchrony and investigate the early diagnostic value of left ventricular systolic dyssynchrony on cardiotoxicity caused by anthracyclines in patients with diffuse large B-cell lymphoma (DLBCL). Methods: Thirty-two patients (22 males, 10 females, age: 22-73(54.4±14.2) years) from June 2016 to January 2019 with confirmed DLBCL and normal gated myocardial perfusion imaging (GMPI) before anthracyclines chemotherapy were enrolled prospectively. GMPI was performed after 6 cycles or more of chemotherapy. Changes of myocardial markers, electrocardiogram (ECG) indicators, left ventricular function indicators including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), peak filling rate (PFR), summed motion score (SMS) and summed thickening score (STS) as well as left ventricular systolic synchrony indicators including phase bandwidth (BW), phase standard deviation (SD) and entropy before and after anthracyclines chemotherapy were analyzed. Paired t test, Wilcoxon signed rank test and χ² test were used for data analysis. Results: Compared with pre-chemotherapy, the left ventricular systolic synchrony indicators were significantly higher than those before chemotherapy (BW: (42.81±11.37)° vs (29.28±8.68)°; SD: (11.65±4.64)° vs (8.79±3.14)°; entropy: (39.84±5.51)% vs (36.19±5.94)%; t values: -9.132 to -3.173, all P<0.05). There were no significant differences in other indicators (t values: -1.161 to 1.750, z values: -1.633 to -0.096, all P>0.05). Of 32 patients, 13 patients (40.62%) had left ventricular systolic dyssynchrony, and the rate of chemotherapy-induced left ventricular systolic dyssynchrony was significantly higher than that of left ventricular dysfunction (15.62%, 5/32; χ²=4.947, P=0.025). All 5 patients with left ventricular dysfunction caused by chemotherapy had left ventricular systolic dyssynchrony. The LVEF of the chemotherapy-induced left ventricular systolic dyssynchrony group was significantly lower than that of the left ventricular systolic synchronization group ((54.54±9.25)% vs (66.79±7.65)%; t=4.087, P<0.01). Conclusion Left ventricular systolic dyssynchrony can be appeared in DLBCL patients after chemotherapy and is significantly earlier than left ventricular dysfunction, which can be an early indicator of cardiotoxicity caused by anthracycline chemotherapy.
