Objective To analyze the correlation between the position and the removal extent of the tumor and the postoperative sodium metabolic disturbance in patients with craniopharyngiomas. Methods Retrospective analysis of the postoperative sodium metabolic disturbance in craniopharyngioma patients admitted from Feb.2006 to Oct. 2010 was performed. Results In the 30 casese,10 cases occurred hypernatremia,9 with hyponatremia and, 2 with fluctuating hyponatremia and hypematremia. One cases died in the population. No sodium metabolic disturbance occurred in patients with craniopharyngiomas located in the interasellar region, whereas 8 occurred in the inter and suprasellar region(61.5% ,8/13) , and 3 occurred post and beside assellar region(60.0% ,3/5) , 10 occurred in the third and lateral cerebral ventricle (100.0%, 10/10). Sodium metabolic disturbance occurred in 15 cases(62. 5% ) among 24 cases underwent total resection,in all 4 cases underwent sub-total resection (100.0% ) ,and all 2 cases underwent paritical resection ( 100. 0% ). The degree of resection was not correlated with Sodium metabolic disturbance(x2 = 3.21 ,P>0.05). Conclusion Sodium metabolic disturbance after craniopharyngioma surgery may be correlated with the position of tumor, but not correlated with the removal extent.

Objective Pressure Ulcer Scale for Healing ( PUSH) was published in 1998 by National Pressure Ulcer Advisory Panel ( NPUAP) as a tool to evaluate the effects of pressure ulcer care.This study aimed to verify the reliability and validity of the Chi-nese version of PUSH in order to provide an efficient and reliable tool for evaluating the effects of pressure ulcer care. Methods Using the Brislin translation model, we translated the English version of PUSH into Chinese and finalized the Chinese version through modifica-tion by an advisory panel, pretests, and verification of its reliability and validity in the care of 126 cases of stage-Ⅱ-Ⅳpressure ulcers. We analyzed the reliability and validity of the scale based on its item scores, content validity, construct validity, Cronbach′s αcoeffi-cient, and test-retest reliability. Results The correlation coefficient value of the total and individual item scores was 0.616-0.963 (P<0.01).Each individual item score was significantly higher in the 27%high-score group (n=35) than in the 27%low-score group (n=36).The total content validity coefficient was 0.965, the correlation coefficient of construct validity between the total and individual item scores was 0.750-0.954 (P<0.01), and that between individual items was 0.666-0.826 (P<0.01), with statistically signifi-cant differences between the total and individual item scores at 7 and 21 days after treatment (P<0.01).The Cronbach′s αreliability coefficient value of the total score was 0.823 and those of individual item scores were 0.770, 0.791, and 0.868, respectively.The inter-rater reliability coefficients were all >0.85 and the test-retest reliabili-ty coefficients of individual items were 0.826, 0.885, and 0.958, re-spectively ( P<0.01) . Conclusion The Chinese version of PUSH, with its high validity and reliability, can be used to evaluate interven-tion effectiveness of Chinese patients with pressure ulcers.

Objective:To systematically review the risk factors of delayed healing of venous leg ulcer (VLU) so as to provide a guide for developing the personalized nursing strategies.Methods:The Cochrane Library, PubMed, Web of Science, ScienceDirect, Clinicaltrials.gov, ProQuest and Open Grey was retrieved with the English keywords of "varicose ulcer/venous ulcer, non-healing/delayed healing/poor healing, factor/risk factor/influence factor"; the China Biological Medicine (CBM) , Chinese National Knowledge Infrastructure (CNKI) , WanFang Data and VIP was retrieved with the English keywords of "venous leg ulcer/venous ulcer, delayed healing/refractory, risk factors/influencing factors"; the retrieval time ranged from building database to 1st April 2019. Two researchers independently screened literatures, extracted data and assessed the quality of included literatures. The RevMan 5.3 was used to the meta-analysis.Results:Finally, a total of 11 literatures were included and involved 3 894 subjects, 520 cases lost to follow up, 914 cases in case group and 2 460 in control group. Meta-analysis showed that there were 7 risk factors related to delayed healing of VLU including the ages [ OR=1.02, 95% CI (1.01, 1.03) , P<0.01], range of motion of ankle [ OR=4.77, 95% CI (1.79, 12.73) , P<0.01], size of ulcer [ OR=1.27, 95% CI (1.10, 1.47) , P<0.01], duration of ulcer [ OR=1.08, 95% CI (1.01, 1.16) , P=0.03], history of deep vein thrombosis (DVT) [ OR=2.21, 95% CI (1.06, 4.63) , P=0.03], ankle-brachial index<0.8 [ OR=8.71, 95% CI (4.22, 17.99) , P<0.01]and rheumatoid arthritis [ OR=1.37, 95% CI (1.08, 1.73) , P<0.01]with statistical differences, and factors irrelevant to delayed healing of VLU including the body mass index (BMI) [ OR=0.98, 95% CI (0.83, 1.16) , P=0.82], >50% wound covered with fibrin [ OR=1.88, 95% CI (0.99, 3.57) , P=0.06], diabetes mellitus [ OR=1.10, 95% CI (0.70, 1.75) , P=0.67], history of hip or knee replacement [ OR=1.73, 95% CI (0.50, 6.00) , P=0.39]. Conclusions:Evidence shows that the independent risk factors of delayed healing of VLU include the ages, range of motion of ankle, size of ulcer, duration of ulcer, history of DVT, ankle-brachial index<0.8 and rheumatoid arthritis. Those evidences can help to identify the clinical high-risk population of delayed healing of VLU and provide targeted nursing intervention to reduce the healing time of VLU and improve patients' quality of life.

OBJECTIVE: To investigate the morphological and hemodynamic parameters associated with middle cerebral artery (MCA)bifurcation aneurysm rupture. METHODS: A retrospective study of 67 consecutive patients was carried out based on 3D digital subtraction angiography data. Morphological and hemodynamic parameters including aneurysm size parameters (dome width, height, and perpendicular height), longest dimension from the aneurysm neck to the dome tip, neck width, aneurysm area, aspect ratio, Longest dimension from the aneurysm neck to the dome tip (Dmax) to dome width, and height-width, Bottleneck factor, as well as wall shear stress (WSS), low WSS area (LSA), percentage of LSA (LSA%) and energy loss (EL) were estimated. Parameters between ruptured and un-ruptured groups were analyzed. Receiver operating characteristics were generated to check prediction performance of all significant variables. RESULTS: Sixty-seven patients with MCA bifurcation aneurysm were included (31 unruptured, 36 ruptured). Dmax (p=0.008) was greater in ruptured group than that in un-ruptured group. D/W (p<0.001) and the percentage of the low WSS area (0.09±0.13 vs. 0.01±0.03, p<0.001) were also greater in the ruptured group. Moreover, the EL in ruptured group was higher than that in un-ruptured group (6.39±5.04 vs. 1.53±0.86, p<0.001). Multivariate regression analysis suggested D/W and EL were significant predictors of rupture of MCA bifurcation aneurysms. Correlation analyses revealed the D/W value was positively associated with the EL (R=0.442, p<0.01). CONCLUSION: D/W and EL might be the most two favorable factors to predict rupture risk of MCA bifurcation aneurysms.

Objective To explore the effect of two methods in stages fusion training clinical nurses to master the knowledge of skin tears identification and prevention in order to provide basic specification for clinical nurses in specialty training. Methods Lecture teaching method and multimedia combined with cases teaching method were set. A total of 85 wound care group nurses received the training in phases. During the first phase, colostomy therapists adopt lecture as the main teaching method on the definition of skin tears, classification standard and the related reasons. Total training time was 1. 5 h. The second phase training started four weeks later. Multimedia combining cases method was adopted as the teaching method. Total training time was 1. 5 h. After each training phrase, pictures of different kinds of skin tears were provided for the scene test. A unified criteria was used to evaluate and review, with qualified score≥85.Results All of 85 nurses completed the test within 1 h. For the first phase with lecture as teaching method, the passing rate was 5.88%. The second phase with the training method of multimedia combining cases, passing rate was 89.41%(P<0.001). Average grades for first stage was (69.95±10.37)which was lower than the second stage(89.58±9.65)(t=15.475,P<0.001). Nursing age, education, job title and work environment had no statistical significance (P>0.05) on mastering the degree of skin tears.Conclusions Two methods in phases training could help nurses understand and grasp the recognition and nursing knowledge of skin tears.

Objective To explore the influencing factors for postoperative adjuvant chemotherapy effects in elderly patients with breast cancer. Methods Five hundred and ninety female patients aged 65 years or older with invasive breast cancer were treated in our hospital, and the influencing factors for postoperative adjuvant chemotherapy effects were analyzed by chi-square test and logistic regression. Results Two hundred and thirty-one (39.2%) patients received postoperative adjuvant chemotherapy. The results showed that diabetes, age, patterns of operation and pathological characteristics of tumor had significant influences on postoperative adjuvant chemotherapy effects (χ2=4.49,88. 27,23.49 and 9.40, all P<0.05). Logistic regression analysis showed that age, tumor size, lymph node status(pN) and estrogen receptor (ER) status were related to postoperative adjuvant chemotherapy effects(χ2=68.857,15. 284,43. 540 and 7.009 ,all P<0.01). Forty-four patients (66.7%) with pN(+)/ER(-) received adjuvant chemotherapy. Conclusions Age, tumor size, lymph node status and ER status were independent predictive factors for postoperative adjuvant chemotherapy effects in elderly patients with breast cancer.
