Objective To investigate how surgical patients are assessed regarding pressure ulcer risks and the usage of evaluation tools in different stages during perioperative period.Methods Totally 210 nurses from operating rooms and surgical wards in 7 tertiary hospitals of Jiangsu Province were investigated with self-designed questionnaire.Results Operating room nurses of 7 hospitals used different kinds of scales for pressure ulcer risk assessment,the same scale document was used during the different stages of operation,the frequency and time for pressure ulcer risk assessment varied from one to three times,preoperative visit to handover in surgical ward were different;the Braden scale was used by surgical nurses to evaluate pressure ulcer risk after operation,while most surgical nurses believed that the existing scale lacked specificity and intraoperative risk factors that should be considered when assessing postoperative patients.Conclusion The frequency and time of pressure ulcer risk assessment of patients during perioperative period are not standardized,the content of scale is limited and lacks specificity,the assessment of pressure ulcer risk during perioperative period is discontinuous and non-dynamic.There are no specific risk assessment scales targeting preoperative,intraoperative and postoperative pressure ulcer risk assessment.

Objective:To define the expression levels of MDM2 gene in nasopharyngeal carcinoma (NPC)and its relationship with p53 protein expression and EB virus latent infection. Method :MDM2 gene expression atmRNA and protein levels,p53 protein and EB virus DNA were detected by nonradioactive in situ hybridization(ISH) ,immunohistochemistry(IHC) and polymerase chain reaction (PCR) separately in 46 cases of NPC tissuesand 12 cases of chronic inflammation of nasopharyngeal epithelium (CINE). Result: Fourteen cases of NPCshowed MDM2 mRNA and protein overexpression, 38 cases were p53 protein positive,and 43 cases were EBV-DNA positive. Neither MDM2 nor p53 protein was expressed in any case of CINE. MDM2 expression was signifi-cantly related to p53 protein expression ( P ＜0. 05), but not to EB virus latent infection in NPC. Conclusion:MDM2 gene may play an important role in the pathogenesis of NPC through interacting with p53 protein.

Objective: To investigate the expression of gluconeogenic enzymes phosphoenolpyruvate carboxykinase (PEPCK) and G-6-Pase mRNA of hepatic tissue in rats with intrauterine growth retardation (IUGR) and to explore the molecular mechanism of insulin resistance in IUGR rats. Methods: Pregnant rats were randomly divided into 2 groups: a normal group and a model group. hTe normal group were fed with 21% protein forage and the model group with 10% low protein forage to obtain IUGR pup rats. hTe pup rats were introduced to the normal group and the IUGR group prospectively. At 1, 3 and 8 weeks, the body weight, blood glucose, insulin concentration andinsulin resistance index of the pup rats were measured. Expression of PEPCK and G-6-Pase mRNA were detected by RT-PCR. Results: The birth weight of the IUGR group was significantly lower than that of the normal group (P<0.001). The weight of the IUGR group was still lower than that of the normal group at 1, 3 and 8 weeks. There was no significant difference in the blood glucose, insulin level and insulin resistance index between the 2 groups (P>0.05). The hepatic expression of PEPCK and G-6-Pase mRNA in the IUGR group was significantly higher than that of the normal group at 1, 3 and 8 weeks (P<0.01). Conclusion: The significantly increased expression of PEPCK and G-6-Pase mRNA of hepatic tissue in IUGR rats may increase gluconeogenesis, which is probably one of the molecular mechanisms of insulin resistance and diabetes in IUGR.

OBJECTIVE: To investigate the clinical efficacy and safety of Yisui Shengxue Granule (YSSXG), a compound traditional Chinese herbal medicine for reinforcing kidney and nourishing blood, in treating hemoglobin H (HbH) disease. METHODS: YSSXG was given orally to 25 patients with HbH disease in Guangxi Zhuang Autonomous Region (high incidence area for HbH disease in China) for 3 months as one therapeutic course, 3 times a day, 10 g YSSXG was given each time (dose of YSSXG for children should be reduced properly), and blood transfusion was not given to HbH patients during the course of treatment. The levels of hemoglobin (Hb), red blood cell (RBC), HbH and reticulocyte (Ret) were observed before and after YSSXG treatment, and side effects were observed during the course of treatment. Meanwhile, the genotype was examined, and the clinical efficacy of YSSXG in treating HbH patients with different genotype was evaluated. RESULTS: The levels of Hb, RBC and Ret were obviously increased after YSSXG treatment from the first month to the end of treatment (P<0.01). After YSSXG treatment, the levels of Hb, RBC, Ret in 12 HbH patients with gene deletion were elevated (P<0.05, P<0.01), and the levels of Hb and Ret in 13 HbH patients with gene non-deletion were increased obviously (P<0.05, P<0.01). The total response rate was 84% after 3-month treatment, and there was no statistical difference in clinical efficacy between gene deletion HbH patients and non-deletion HbH patients. No adverse effect was observed during the course of treatment. CONCLUSION: YSSXG is effective and safe for treatment of HbH disease. YSSXG can improve the levels of Hb, RBC and Ret in HbH patients, especially in gene deletion HbH patients.

To explore the relationship between syndromes of traditional Chinese medicine (TCM) and genetic background in patients with beta-thalassemia.

OBJECTIVE To observe the regulation effect of chidamide on energy metabolism in HCT-8 and HT-29 cells. METHODS HCT-8 and HT-29 cells were treated with chidamide 5,10 and 20 μmol · L-1. Morphological changes of these cells were observed under an ordinary optical microscope. Cell proliferation was detected by MTT. ATP production was determined by CellTiter-Glo? assay kit. Metabolic changes were tested by glycolytic stress kit. The mRNA level of lactate dehydrogenase A (LDH-A)was analyzed by real-time quantitative PCR,whereas the protein level of LDH-A was analyzed by Western blotting. RESULTS Compared with control group,cell morphology of HCT-8 and HT-29 cells in chidamide treated group was irregular,accompanied by deformation,shrinkage and cell debris, and the inhibitory rate of proliferation increased(P<0.05). There was no significant difference in ATP total content between chidamide 5 and 10 μmol · L-1 16 h treatment groups,but in chidamide 20 μmol · L-1 treatment group it was decreased(P<0.05). Chidamide 20μmol · L-1 had no effect on oxygen consumption rate, but glycolysis ATP generation rate was reduced by 30.7% and 37.9%(P<0.05),respectively. Chidamide 20μmol · L-1 had no effect on LDH-A mRNA level,but it decreased the protein level of LDH-A(P<0.01). CONCLUSION Chidamide can abate the respiratory metabolic ability of HCT-8 and HT-29 cells. The mechanism may be related to the down-regulation of LDH-A.

Objective To investigate the caring experiences of family caregivers of patients with enterostomy in different stages based on"Timing It Righ"framework. Method Phenomenological research method was used to conduct an unstructured interview with 40 caregivers of patients in different stages (perioperative period, discharge preparation period, adjustment period and adaptation period).The acquired data were analyzed by Colaizzi phenomenological research method. Result According to the"Timing It right"framework, five themes about nursing experience of caregivers of patients with enterostoma at different stages were extracted: 1) uncertainty of disease and post-traumatic stress disorder at the perioperative period; 2) Re-challenges after subjective initiative adjustment during the discharge preparation period; 3) practice and re-cognition during the adjustment period; 4) post-traumatic growth during the adaptation period.Conclusions The caregiver's experience of an enterostomal patient presents a dynamic process. There are different experiences and needs for inner-heart care in different stages.Family caregivers were with strong information and emotion need at the perioperative period;they were with strong helpless feeling during the dischsrge preparation;they were with information and stoma instrument need in adjustment period;they were with care ability need during adaption period. Nursing staff should provide relevant mental support and professional guidance up to the different stages so as to improve mental health of caregivers of stoma patients and enhance their knowledge and skills on care-giving.

Objective:To investigate the resilience level and self-management status of patients with type 2 diabetes and analyze the mediating effect of mindfulness level between the resilience and self-management behavior.Methods:Totally 219 patients with type 2 diabetes from December 2019 to April 2020 were selected as the research subjects.The general information questionnaire, Mindful Attention Awareness Scale, Connor-Davidson Resilience Scale, and the Summary of Diabetes Self-Care Activities were used to investigate all patients.SPSS 22.0 was used for statistical analysis.Spearman correlation analysis was used to analyze the relationship among the variables, and multiple linear stepwise regression analysis was used to analyze the mediating effect.Results:The correlation analysis showed that resilience(45.0 (40.0, 50.0)) was positively related to self-management(14.0 (9.0, 22.0)) ( r=0.876, P<0.05), and mindfulness(46.0 (40.0, 57.0)) ( r=0.838, P<0.05). Mindfulness was positively related to self-management( r=0.821, P<0.05). The mediating effect test showed that mindfulness played a part of mediating role between resilience and self-management, with the mediation effect of 0.56, accounted for 69.80% of the total effect. Conclusion:The variables of mindfulness, mental resilience and self-management behavior in type 2 diabetic patients are positively correlated with each other.Mindfulness plays a partial mediating role between mental resilience and self-management behavior.
