Objective To understand the degree of resilience of emergency nurses and ICU nurses, and analyze the effects of resilience on work engagement of nurses working in the emergency and ICU departments in tertiary hospitals in Chengdu city. Methods This was a cross-sectional survey. A total number of 660 nurses from7 hospital in Chengdu were selected by a convenient sampling method. Results The mean resilience score of the emergency and ICU nurses in Sichuan province was (123.07± 23.76) points, the mean score of work engagement was(2.70±1.20) points. There was a positive relationship between emergency and ICU nurses′ resilience score and nurses′ work engagement (r=0.394, P < 0.01). Nurses with higher level of resilience indicated higher work engagement score (F=35.77, P < 0.05). Conclusions The resilience score of the emergency and ICU nurses in tertiary hospitals of Chengdu city was at a low level. Higher resilient emergency and ICU nurses tended to have the higher level of work engagement.

iRGD-modified sterically stabilized liposomes loaded doxorubicin (iRGD-SSL-DOX) were prepared and their cellular toxicity and anti-tumor efficacy were evaluated, comparing to doxorubixin loaded sterically stabilized liposomes (SSL-DOX) and RGD modified doxorubixin loaded sterically stabilized liposomes (RGD-SSL-DOX). The iRGD peptide, with both tumor targeting and cell penetrating functions, was conjugated to DSPE-PEG-NHS and DSPE-PEG-iRGD was obtained. DSPE-PEG-RGD was gained in the same way. iRGD-SSL-DOX, RGD-SSL-DOX and SSL-DOX were prepared by ammonium sulfate gradient method. The size and zeta potential of the liposomes were characterized by dynamic laser light scattering. The cellular toxicity study was done on B16 melanoma cell line and the anti-tumor efficacy study was carried on B16 cell line bearing C57BL/6 mice. The results showed that the particle sizes of liposomes were all around 90-100 nm. DOX entrapment efficiency was above 95%. The formulations were with good preparation reproducibility. iRGD-SSL-DOX showed no significant difference in B16 cellular toxicity with SSL-DOX and RGD-SSL-DOX, but the anti-tumor efficacy on B16 melanoma bearing C57BL/6 mice was significantly better than that of SSL-DOX, similar as that of RGD-SSL-DOX. Therefore, iRGD modified liposomes loaded DOX would be a promising drug delivery system for tumor therapy.

Objective To investigate the expression and im plication of cell-cycle related factors(Cyclin D1,CDK4,P16 MTS1 and PRb)in condyloma acuminatum(CA).Methods The expression and distribution of cyclin D1,CDK4,P16 MTS1 and PRb were detected by immunohisto chemical technique streptavidin peroxidase(SP)in 27cases of HPV6/11positive CA that were confirmed by PCR and 10cases of norm al skins(foreskins).Results①Cyclin D1was not expressed in both normal skin and lesions of CA.②The intensity of expression of CDK4was 2.19in the basal cells in the lesions of CA,which was significantly weaker than that in normal skin(4.8,P

Obtective The correlation between estrus cycle and the pathological changes of liver and lung in LPS-treated mice and the possible mechanisms were investigted.Methods The pathological lesion in liver and lung、 the content of E_2、P in plasma and the content of TNF-?、EGF in plasma and ovarian supernate were examined in various times after challenge with 12.5 mg/kg LPS in estrus、metestrus and diestrus respectively and the correlation among them was assessed.Results The plasma E_2 and p levels were the lowest in diestrus.When LPS was injected in diestrus,compared with control group,the levels of P and E_2 in plasma were decreased remarkely after ip LPS 10 h(P

Cerebral arteriovenous malformation (AVM) is a common cerebrovascular disease in clinical practice. Although the treatment of AVMs has been w idely studied, the prognosis of the patients does not get significantly improvement. The main therapeutic purpose of AVMs is to reduce the risk of bleeding. This article review s the risk of bleeding and treatment modalities of AVMs.

Objective To analyze the willingness of community medical staff to accept the day surgery mode and analyze the reasons.Methods Convenience sampling was used to investigate the medical staff in five community hospitals.Results A total of 308 participates were investigated,85.3％ of them expressed that they have heard about the ambulatory surgery model,while 99.4％ of them (306 participates) were willing to accept this surgery mode after we explained to them,and they thought that the ambulatory surgery mode could shorten the preoperative waiting time,and the most worrying aspect of the ambulatory surgery mode was fear of no medical personnel and inadequate preparation for patients in medical knowledge.Conclusions Ambulatory surgery mode is a kind of safe and effective medical model.The acceptance of community medical staff is high,but there is a certain risk perception.

Objective To establish a hospital-community transitional care network for patients with day surgery, provide hierarchical medical, ensure patients safety and promote the standardization of day surgery. Methods West China Hospital Day Surgery Center established the hospital-community transitional care network for day surgery on March 2012. A total of 40 community hospitals in Chengdu joined the network. Community medical personnel were trained with community training, public lectures, visiting and learning. Transitional care were carried out by gratuitous treatment, telephone follow-up, family visit, and two-way referral system. Results A total of 689 patients with day surgery received transitional care in community hospitals, and 94 patients were transferred to superior hospital from January to October 2017. Community hospitals can provide transitional care including dressing change, medication guidance, attention of patients' rehabilitation, and reminding the on-time reexamination for patients with day surgery. Conclusions The hospital-community transitional care network can promote the subsidence of high quality medical resources, and is benefit to the implementation of hierarchical medical and the safety of patients after day surgery.

Objective:To investigate the causal relationship between childhood narcolepsy and allergic rhinitis using two-sample Mendelian randomization; To provide references for clinical prevention and treatment.Methods:Genetic variants closely related to narcolepsy were extracted from GWAS summary data as instrumental variables, with allergic rhinitis (AR) as the outcome variable. The narcolepsy data included 335 410 samples and 10 894 596 single nucleotide polymorphisms (SNPs). The AR data included 5 527 cases and 212 387 controls, with a total of 16 380 461 SNPs. Two-sample Mendelian randomization analyses were conducted using inverse variance weighted, weighted median, and MR-Egger regression methods mainly to evaluate the causal relationship between narcolepsy and AR with OR. Heterogeneity testing, pleiotropy assessment, and sensitivity analysis were used to evaluate the stability and reliability of the results.Results:A total of 42 SNPs were included as instrumental variables. It was found that the estimated effect of narcolepsy on AR was greater than 1 and with statistical significance [ OR(95% CI)=1.79(1.02,3.13), P=0.04]. Conclusions:There may be a positive causal relationship between narcolepsy and AR. "Phlegm-dampness impairing the spleen" is a common pathogenic mechanism between the two diseases.
