Objective To evaluate the Chinese version of Benefit Finding Scale (BFS) for breast cancer patients.Methods After consent of the author,according to the flow path of scales,we established the psychometric properties of the Chinese version of BUS,a convenience sample of 293 patients were recruited for evaluation.Results The Chinese version of BFS was comprised of 19 items,Cronbach's α coefficient was 0.911,test-retest reliability was 0.812,I-CVI was 0.833～1.000,S-CVI was 0.955.Meanwhile,exploratory analysis showed that the most interpretable solution consisted of 3 factors,the accumulative variance contribution which explained 55.101％ of variance of the total scale.The related validity showed that the correlative coefficient of Chinese version of BUS and Posttraumatic Growth Inventory (PTGI) was 0.745.Conclusions It suggests that the 19-item Chinese version of the BFS has good reliability and validity,which could be used as a research tool for measuring breast cancer patients' benefit finding.

AIM: To investigate the effects of auricularia auricular polysaccharide (AAP) on chronic cerebral ischemia injury in rats. METHODS: The chronic cerebral ischemia mode1 was made by permanent middle cerebral artery occlusion (MCAO) on the right side. AAP at different doses (50 mg/kg and 100 mg/kg) was intragastrically administered at the onset of ischemia and in the following days after operation, once a day for 4 weeks. After 4 weeks of MCAO, Morris water maze test was introduced to examine the learning and memory functions. Nissl staining was performed to detect the survival neurons in hippocampal slices. Level of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) in brain tissue were measured. RESULTS: Rats treated with AAP showed a shorter escaping latency in spacial navigation test because the AAP treated rats spent less time to find the platform in spatial probe test. More survival neurons in hippocampal slices were observed from AAP treated rats. Also, the MDA level in brain tissue was reduced and SOD activity in brain tissue was increased in the AAP treated rats with MCAO. CONCLUSION: AAP protects rats from chronic brain ischemic injury, in which its anti-oxidative effect might be involved.

AIM: To investigate the protective effect of auricularia auricular polysaccharide (AAP) on the myocardial injury induced by ischemia and its underlying mechanism. METHODS:AAP was orally administrated to rats at the does of 50, 100 or 200 mg·kg~(-1)·d~(-1) for 20 d. Myocardial injury was induced in anesthetized Sprague - Dawley rats by left anterior descending coronary artery ligation. Myocardial infarct size, the level of lactate dehydrogenase (LDH), the activity of superoxide dismutase (SOD) , the production of lipid peroxidation malondialdehyde (MDA) and protein level of myocardial collagen of the heart were measured. RESULTS: The average myocardial infarct size in AAP groups was significantly smaller than that in ischemia group. The level of serum LDH induced by regional myocardial ischemia was significantly decreased in AAP group compared to ischemia group ( P < 0.01). AAP inhibited the production of MDA and increased the activity of SOD. Furthermore, AAP reduced the protein level of myocardial collagen after ischemia (P < 0.01).CONCLUSION: AAP prevents myocardium from ischemia injury as an antioxidant.

Objective To study the effects on tissue CT number caused by scan protocols.Methods The phantom was repeatedly scanned in different protocols by changing only one of parameters,such as X-ray tube voltage,mAs and recon kernel,while other parameters were ketp unchanged.The CT number of different materials in phantom were measured and analyzed.Results The CT numbers of tissues changed remarkably with the tube voltage and had different relativity for different tissues.The CT numbers had positive correlation with kV for such maierials as polyethyle,lexan,perspex,but for teflon the correlation was negative.The mAs and recon kernel had no effects on CT number.Conclusions The CT number of tissue changes with scanning X-ray tube voltage,so the setting of scan parameters should be taken into account in image diagnosis and radiotherapy.

Objective To investigate the P2X3 receptor expression in L6-S1 dorsal root ganglion (DRG)and bladder detrusor in a rat model of neurogenic bladder and urethra. Methods Eighty Sprague-Dawley rats wererecruited and randomly divided into a sacral injury group, a suprasacral injury group and a control group. Spinal tran-section was performed to establish the animal model of neurogenic bladder and urethra in rats of the sacral injurygroup and suprasacral injury group. Check the P2X3 receptor expression in DBG and bladder detrusor among thethree groups by Western blot test at 20 days after model establishment. Results P2X3 receptor expression in L6-S1DRG of sacral injury group was significantly less than that of the suprasacral injury group, which was in turn signifi-cantly higher than that of the control group. P2X3 receptor expression in bladder detrusor of sacral injury group wassignificantly lower than that of the suprasacral injury group, which was in turn significantly higher than that of thecontrol group. Conclusion There was close relationship between P2X3 receptor expression and dysfunction of blad-der and urethra.

Objective To investigate the effect of periurethral injection of insulin-like growth factor(IGF)-Ⅰ on the expression of IGF-Ⅰ and IGF-Ⅱ mRNA during regeneration period following urethral sphincter muscle injury in female rats. Methods Model of urethral sphincter muscle injury was made in female virgin SD rats (n=50) by intravaginal balloon inflation. Then the rats were divid-ed randomly into treatment group (n= 25) and control group (n= 25), treatment group accepted peri-urethral injection of 1.0μg human IGF-Ⅱ to the middle urethral muscle, control group accepted nor-mal saline injection. Five rats in each group were sacrificed at 2, 4, 6, 8, 14 day respectively and the whole urethra specimens were processed for RT-PCR to detect the expression of IGF-Ⅰ ,Ⅱ mRNA. A normal control group (n = 5) was set without intravaginal balloon inflation and injection. Results The expression of IGF-Ⅰ mRNA in control group increased at day 4, 6, 8, 14, the IGF-Ⅰ/β-actin ra-tios were 0. 58±0.15, 1.73±0.31, 2.30±0.29, 0. 46±0. 06. The expression of IGF-Ⅰ mRNA in treatment group increased at all time points, as 0. 69±0.21, 1.45±0.17, 2.25±0.45, 2.90±0.49, 1.92±0. 31. The difference was significant on day 4, 14(P<0.01), and day 8 (P<0.05) compared with the control group. The expression of IGF-Ⅱ mRNA in control group increased at day 4, 6, 8, as 0.42±0. 14, 1.51±0. 59, 1.31±1.04. The expression of IGF-Ⅱ mRNA in treatment group in-creased at day 4, 6, 8, 14, as 1.04±0.23, 1.94±0.29, 1.75±0.41, 0. 81±0.15. The significant difference was noted on day 4 (P<0. 01)compared with the control group. No expression of IGF-Ⅰand Ⅱ mRNA in the normal control group. Conclusions The expression of endogenous IGF-Ⅰ and IGF-Ⅱ mRNA was up-regulated by periurethral injection of IGF-Ⅰ during regeneration period follow-ing urethral sphincter muscle injury in female rat. Our findings suggest that IGF-Ⅰ facilitates the re-generation of the urethral muscles and may play a role in treatment of stress urinary incontinence in-duced by urethral sphincter muscle dysfunction.

Objective:To investigate the value of MR subtraction images in improving the interobserver agreement for Bosniak Ⅱ, ⅡF, and Ⅲ cystic renal masses (CRMs) with Bosniak classification version 2019.Methods:From January 2009 to August 2020, 323 patients (335 CRMs) with surgical pathology results and complete preoperative MRI examination (T 2WI, T 1WI precontrast images and enhanced MRI in corticomedullary, nephrographic, and excretory phases) were retrospectively collected in the First Medical Center of PLA General Hospital. The CRMs of Bosniak Ⅱ, ⅡF, and Ⅲ were selected and classified by 2 experienced genitourinary radiologists according to the Bosniak classification version 2019. The "Subtraction" function in the American GE ADW 4.4 workstation was used to perform subtraction images reconstruction on the enhanced images in the corticomedullary, nephrographic, and excretory phases. Blinded to pathologic information, the other 2 radiologists independently classified the enrolled CRM cases with and without subtraction MR images, respectively, with an interval of 1 month. Ultimately, by using weighted Kappa value, interobserver agreement was evaluated, and the differences in weighted Kappa value were compared using the Gwet coefficient. Results:A total of 187 patients with 187 CRMs were enrolled in the study. The results of the classification of Bosniak Ⅱ, ⅡF, and Ⅲ CRMs categorized by 2 radiologists without and with subtraction images showed that 119 and 141 cases were consistent, and 68 and 46 were inconsistent, respectively. The weighted Kappa value for interobserver agreement among two radiologists without and with subtraction MR images was 0.60 (95%CI 0.53-0.68) and 0.73 (95%CI 0.66-0.80), respectively. The interobserver agreement was higher with subtraction images than that without subtraction images ( t=-2.56, P=0.011). Conclusion:According to the MRI criteria of Bosniak classification version 2019, the interobserver agreement for Bosniak Ⅱ, ⅡF, and Ⅲ CRMs could be improved using subtraction MR images, which may facilitate the popularization and application of Bosniak classification version 2019.

Objective? To analyze the risk factors of nosocomial infection in the pediatric ward in a hospital and nursing care for relevant prevention and control. Methods? Totally 1 460 pediatric inpatients admitted in Taizhou First People's Hospital from June 2017 to January 2019 were retrospectively analyzed and divided into the infection group and the control group according to the existence of infection. The children＇s medical records were organized; the risk factors of nosocomial infection in pediatric inpatients were analyzed;and relevant nursing measures were summarized. Results? Nosocomial infection was found in 89 out of the 1 460 children; most children were found with respiratory tract infection and digestive canal infection in the infected children, which accounted for 36 cases (40.4%) and 23 cases (25.8%), respectively; the proportion of children aged ＜3 years, hospitalized for ＞10 days, with malnutrition, invasive operation, receiving antibiotics for ＞10 days, or receiving immunosuppressors or unqualified sterile operation in the infection group was higher than that in the control group, and there was statistically significant difference between the two groups (P＜ 0.05). Logistic regression analysis revealed that nosocomial infection in pediatric inpatients was associated with length of hospital ＞ 10 days, invasive operation, use of antibiotics for ＞ 10 days, use of immunosuppressors and unqualified sterile operation. Conclusions? Pediatric inpatients are prone to nosocomial infection, and the type of infection is mainly respiratory tract infection and digestive canal infection. Relevant nursing measures should be taken based on the factors of infection in order to reduce the incidence rate of nosocomial infection in children.

Objective:To explore the effects of different temperature settings on patients with acute hypoxic respiratory failure (AHRF) during application of high-flow nasal cannula (HFNC) .Methods:A total of 90 patients with AHRF who were admitted to the Department of Critical Care Medicine of Zhejiang Hospital and underwent HFNC from January 2019 to May 2020 were selected as research objects by the convenient sampling method. The patients were randomly divided into 3 groups by the random number table method, namely, group A (T=31 ℃) , group B (T=34 ℃) and group C (T=37 ℃) , with 30 cases in each group. The VAS and Borg Scale were used to compare the comfort and dyspnea of patients of 3 groups, and to compare the satisfaction of patients of 3 groups.Results:After applying HFNC for 2 h and 12 h, the scores of VAS and Borg Scale in group B were lower than those in groups A and C, and the differences were statistically significant ( P<0.01) . The VAS scores of the three groups after applying HFNC for 12 h were higher than that after applying HFNC for 2 h, and the scores of Borg Scale were lower than that after applying HFNC for 2 h, and the differences were statistically significant ( P<0.05) . The satisfaction of patients in group B was higher than that in group A and C, and the differences were statistically significant ( P< 0.01) . Conclusions:Different temperature settings of HFNC will affect the comfort, dyspnea and satisfaction of AHRF patients. Among them, 34 ℃ is a more suitable temperature. As time progresses, nursing staff should intervene in time to maintain the comfort of patients, reduce the degree of dyspnea and provide guidance for the clinical application of HFNC.
