Severe acute biliary pancreatitis can be treated by nonsurgical and surgical approaches,and choice of the surgical techniques as well as its timing are the keys points to the whole therapy.Early enteral nutrition via placing nasointestinal feeding tube plays an important role in the nutritional support for patients with severe acute pancreatitis.This paper intends to explore the experience in standardizing the therapy for all similar cases via reviewing and summarizing the treating process of a typical patient with severe acute biliary pancreatitis.

Objective To investigate the real situation of the burden of the caregivers who take care of patients with spinal cord injury.Methods Using phenomenological research methods of qualitative study,information of 15 family caregivers of patients with spinal cord injury were collected through semi-structured interviews in Jiangxi province,and data were analyzed with Colaizzi 7-step analysis method.Results Four themes were summarized:weak social support system,heavy economic burden,insufficient care ability,mental and physical exhaustion; mental and physical exhaustion concluded three sub-themes:burnout,lifestyle changes,sad/helplessness.Conclusions Care burden of caregivers of patients with spinal cord injury includes four aspects:social,physical,psychological,and less caring capacity.Care workers should be concerned about the health status of the caregivers,give targeted care intervention,so that caregivers can be adapted to the caregivers' role,maintain and promote a high level of health of the patients and their families.

Objective To investigate the level of care burden and self efficacy of caregivers of patients with spinal cord injury,and analyze their correlation.Methods By convenience sampling method,150 cases of spinal cord injury patients and their caregivers were investigated with Zarit Caregiver Burden Scale and general self-efficacy scale.Results The score of care burden of caregivers with spinal cord injury was (52.91 ± 11.56) points,self-efficacy score of caregivers was (19.63 ± 4.85) points.The score of care burden of caregivers and self-efficacy was highly negatively correlated.Conclusions We should pay more attention to improve the self-efficacy of caregivers of patients with spinal cord injury (SCI),in order to mitigate the care burden,improve care ability and health level of the patients' families.

Objective To investigate the dynamic expression of mRNA and protein of surfactant protein C (SPC),E-cadherin (E-cad),N-cadherin (N-cad) and α-smooth muscle actin (α-SMA) and elucidate the significance of epithelial-mesenchymal transition (EMT) in a newborn rat model of Bronchopulmonary dysplasia (BPD).Methods A newborn rat model of BPD in hyperoxia was established,and a control group exposed to air was established.Lung tissue was collected on days 3,7,14,and 21,respectively.Alveolar development was evaluated by radical alveolar counts(RAC),including thickness of alveolar septum,ratio of alveolar and septa.Real-time PCR and Western-blot were used to detect levels of markers of epithelial cells (SPC,E-cad) and interstitial cells (N-cad,α-SMA) in AT2 and protein expression.Results On day 7,14,and 21,compared with the control group,RAC (7.38 ± 0.92,9.25 ± 0.70,9.88 ± 0.99) and alveolar area/pulmonary septal area ratios (A/S) (2.53 ± 0.02,3.34 ± 0.09,3.96 ± 0.13) were all higher in BPD group [RAC (5.88 ± 0.83,5.14 ± 0.83,4.38 ± 0.52) and A/S (1.88 ± 0.03,1.95 ± 0.03,1.89 ± 0.02)] (all P ＜ 0.05) ; the alveolar septum (8.53 ± 0.04,10.75 ± 0.46,13.55 ± 0.84) in BPD group were thicker than those (5.77 ± 0.09,4.40 ± 0.12,3.67 ± 0.18) in the control group (all P ＜ 0.01).The expressions of SPC and α-SMA in BPD group were significantly higher than those in the control group on day 14 and 21 (all P ＜ 0.05).The level of E-cad mRNA (2.43 ± 0.60,2.59 ± 0.48,3.37 ± 0.53) and protein (18.39 ± 1.77,18.29 ± 1.52,11.48 ± 1.72) for E-cad were higher in the control group than those (mRNA:1.48 ± 0.55,1.57 ± 0.48,1.12 ± 0.45 ;protein:9.50 ± 1.38,8.57 ± 1.06,8.22 ± 1.31) in BPD group was lower(P ＜ 0.05),while the level of N-cad was significantly higher(P ＜ 0.05) on day 7,14,and 21.Conclusions In the development of BPD,the markers of lung epithelial cells were down regulation,while the markers of interstitial cells were up-regulation,and these findings suggest that EMT from lung epithelial cells contributes to the occurrence of BPD.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

Sulfated polysaccharide from Porphyra haitanensis showed inhibitory effect on the lipid peroxidation in vitro. In the present study, the changes in the antioxidative enzyme activity, lipid peroxidation, and total antioxidative capacity (T-AOC) in different organs after 60 Co irradiation were detected in mice by using biochemical methods. Increased endogenous lipid peroxidation and decreased contents of T-AOC as well as decreased activities of super-oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were observed in mice after 60Co irradiation. Intraperitoneal administration of polysaccharide fraction F2 significantly decreased the lipid peroxidation. F2 treatment increased T-AOC and the activities of SOD and GSH-Px in all organs tested in 60Co irradiated mice. It is concluded that the sulfated polysaccharide fraction F2 from Porphyra haitanensis can be used in compensating the decline in antioxidative capacity arising from radiotherapy and thereby reduced the risks of lipid peroxidation.

Objective To study the complete genome sequence of Hantavirus ZT71 strain gene isolated in Zhejiang province and explore its evolution. nethods The total RNA was prepared from ZT71 virus infected cells and the RT-PCR products were cloned into T vector, sequenced and analyzed. Results The L, M and S segments of the strain ZT71 genome were 6530,3651 and 1753 nucleotides in length with a single open reading frame individually encoding 2151,1133 and 429 amino acids. The sequence analysis of nucleotides showed that the homology of L, M and S segments of strain ZT71 between those of other strains of Seoul virus could reach 95.5%-99.7%, 84.1%-99.6% and 88.7%-99.5%, respectively. The analysis of the deduced amino acids showed the similar result. The source of strain ZT71 could be traced from the analysis of the phylogentic trees of nucleotides and amino acids, and it should belong to Seoul type of Hantavirus which was also verified serologically. Conclusion The nucleotide sequences and deduced amino acid sequences of L, M and S segments of strain ZT71 are similar to that of those of Seoul type of Hantavirus. And Hantaan type virus used to be prevalent primarily in Zhejiang province,and it would be an endemic area of mixed type of Hantavirus since the discoveries of the viruses of Soeul type in recent years.

Objective To investigate the relationship of the neutrophil to lymphocyte ratio (NLR)with stroke in elderly persons with CDK.Methods Totally 220 subjects with stage 3-5 CKD were followed.Fatal and nonfatal cerebrovascular event (CVE) were recorded during this period.NLR at baseline was determined from complete blood count differential.We investigated if NLR could predict stroke.Resuits Median NLR was 2.13.NLR was equally associated with estimated glomerular flitrationrate (eGFR).Totally 116 strokes occurred during follow-up period.NLR could predict stroke independently.Increased NLR over 2.13 was related to a significantly decreased survival time (log-rank Chi-square =4.963,P =0.026).Multivariate Cox regression analysis showed that the risk factor of ischemic stroke in CKD patients was high NLR,hazard ratio (HR) 1.11 [95％ confidence interval (CI) 1.007 to 1.223,P =0.035].Conclusions NLR could independently predict stroke in elderly patients with moderate to severe CKD.

Objective To investigate the status of self-management in patients with chronic heart failure (CHF) in Zhejiang province, and to explore the relationship between the self-management level and medical coping styles. Methods From March to September 2016, using the convenient sampling method, a total of 450 aged patients with chronic heart failure from 5 Class Ⅲ Grade A hospitals in 3 districts including Ningbo, Pinghu and Jiaxing of Zhejiang province, who were hospitalized in the Cardiovascular Department, were recruited as research subjects. The Self-Management Scale of Heart Failure Patients and Medical Coping Modes Questionnaire (MCMQ) were applied in the investigation to carry out the correlation analysis. Results A total of 450 questionnaires were distributed, and 437 valid questionnaires were collected. The Self-Management Scale of Heart Failure Patients in the 437 patients were (51.48±10.77) in total score, (18.90±3.10) in facing coping style, (16.12±2.18) in avoiding coping style and (11.85±1.82) in yielding coping style. Pearson correlation analysis showed that the total score of self-management was positively correlated with facing coping style (r=0.303, P＜0.01), negatively correlated with yielding (r=-0.157, P＜0.01), and positively correlated with avoiding coping style (r=0.117, P＜0.01). Multiple linear stepwise regression analysis showed that family monthly income, self-care ability and marriage were the main factors affecting self-management of patients with chronic heart failure. Conclusions Self-management level in patients with chronic heart failure in Zhejiang province is relatively low, and effected by family income, self-care ability, marriage and other factors. Nursing staff should understand different characteristics of different patients to provide personalized health education, improve their self management level, and promote the patients more actively face the disease, reduce and avoid negative medical coping.
