Objective To investigate the status of personality, family function and psychological resilience towards employed nurses, and to explore the relationship among personality, family function and psychological resilience. Methods Four instruments were applied to investigate 240 employed nurses from comprehensive Grade 3A hospital of Fujian Province, which were the Characteristics Questionnaire, Family Intimacy Scale (FACEⅡ-CV), Self-resilience Scale and Personality Traits Questionnaire. Results The correlation analysis showed that nurses′ personality traits, family functions and psychological resilience were closely related. The multiple regression and analysis showed that 40%of the variance for employed nurses′psychological resilience could be explained through considering personality dimensions, family cohesion and adaptability. Conclusions Personality, family functions and psychological resilience towards employed nurses are closely related as both internal and external protective factors.

In order to investigate whether Laribacter hongkongensis could be detected in stool samples of Rattus norvegicus in the wild,Rattus norvegicus were trapped alive in an urban community of Guangzhou,China over a period of one year from June 2015 to May 2016,and their stool samples were examined for the presence of L.hongkongensis strains.Isolates were identified based on phenotypic characteristics and 16S rRNA sequence analysis,and were examined for their susceptibility to 19 antimicrobial agents.Further typing of the isolates was performed using multi-loci sequence typing (MLST) analysis.A total of 191 R.norvegicus were trapped alive.L.hongkongensis was identified and successfully isolated from two samples,representing a prevalence of 1.05 ％.Although the two isolates possessed similar phenotypic characteristics and have no base difference of 16S rRNA gene,they constituted two new distinct sequence types (STs),ST-163 and ST-164.This is the first report that L.hongkongensis can be detected in the intestinal tract of R.norvegicus.Results suggest that R.norvegicus could serve as carriers of L.hongkongensis and therefore could be another potential source of infection.

Two cases of nevus of Ota resistant to multiple sessions of Q-switched laser treatment are reported.Both of the patients were females,who developed beige or blue patches on the left side of the face (zygomatic region,cheek)several months after birth.No conjunctiva or sclera was involved.The lesions spread to the left retroauricular region and posterior neck during pregnancy in one patient.Histopathological examination of the lesions showed scattered melanocytes and melanophages in lower dermis and subcutaneous adipose tissue as well as apparent proliferation of collagen.Immunostaining for CD34 showed no abnormality in the distribution of vascular endothelial cells in these tissues.No obvious improvement was observed in either of the patient after more than 10 sessions(12 sessions in 1 case,and 13 sessions in the other case)of treatments with Q-switched alexandrite(755 nm)or Q-switched Nd:YAG laser(1064 nm).The immediate response of lesions to laser irradiation was unusual.Purpura or errhysis was absent in the lesions after repetitive irradiation with high-energy laser,but both were visible in the adjacent normal skin even after irradiation with low-energy laser.

Objective To investigate the memory monitoring ability in patients with hepatolenticular degeneration(HLD) and explore the mechanism of their memory impairment.Methods The feeling-of-knowing (FOK) paradigm of episodic memory(EM) and semantic memory(SM)were established and subsequently applied to 30 HLD patients and 30 healthy control(HC) participants who were matched in age and educational level.Results Compared with healthy control group (FOK-EM recall (64.17 ± 29.21) ％ ; FOK-SM recall (84.72 ± 11.44)％),the FOK-EM recall((26.55±20.92)％) and FOK-SM recall((53.93±28.42)％) in HLD patients were significantly lower(t=-5.140,P＜0.01 ; t=-5.123,P＜0.01).The positive judgment and correct recognition of FOK-EM ((50.64±29.43) ％) and the negative judgment and correct recognition of FOK-EM((12.80± 18.32) ％) in the HLD group were significantly different from the HC group (the positive judgment and correct recognition of FOK-EM:(75.15±31.73)％ and the false judgment and correct recognition of FOK-EM:(1.81±5.41)％; t=-2.693,P＜0.05 ; t=3.026,P＜0.01).Most importantly,the stroop effect was positively correlated with the negative judgment and correct recognition of FOK-EM in HLD group(r=0.601,P＜0.01).Conclusion The results show that the HLD group underestimate their memory performance on episodic FOK,and the impairment of memory monitoring is positively correlated with the deficit of executive function,indicating that the prefrontal impairment can be an influential factor of memory disorder in HLD,whereas the unimpaired semantic metamemory FOK indicates the episodic and semantic metamemory monitoring may depend on different neural network.

0.05). Significant difference in diffused carbon monoxide percentage and change of heart rates before and after stair climbing test was found in LPF group (P0.05).Conclusions Patients of lung cancer intolerable for lobectomy by static pulmonary function test can be screened by stair climbing test before surgical operation,which can make some of them regain opportunity of surgical operation.

Objective:To explore the influence of treatment with HMG-CoA reductase inhibitors ( sta-tins) on the expression profile of microRNAs ( miRNAs) in the plasma of patients with unstable angina ( UA) .Methods:The Taqman low-density miRNA array ( TLDA) and significance analysis of microar-rays ( SAM) were used to identify distinct miRNA expression profiles in the plasma of UA patients treated with long-term and regular statins ( UA receiving statins , n=6 ) compared with UA patients who had not received statins therapy before ( UA received no statins , n=6 ) .These differentially expressed miRNAs discovered in the profiling were further validated by real-time PCR in another 20 controls with non-cardiac chest pain , 26 UA patients received no statins , and 19 UA patients received statins .Results: By using TLDA and SAM , significantly decreased expression levels of 21 miRNAs were observed in the UA pa-tients receiving statins compared with those who received no statins ( fold change >3 and false discovery rate<0 .0001%) .The unsupervised hierarchical clustering based on miRNA expression clearly separa-ted the UA patients receiving statins from those who received no statins .Consistent with the profiling da-ta, the levels of 5 inflammation-associated miRNAs (miR-106b, miR-21, miR-25, miR-451, and miR-92a) were down regulated (P<0.05) in the UA patients receiving statins compared with those who re-ceived no statins.Conclusion: A group of inflammation-associated miRNAs, consisting of miR-106b, miR-21, miR-25, miR-451, and miR-92a, could be decreased by treatment with statins and may be used as a novel biomarker for effectiveness of statins therapy in patients with UA .

Objective To explore the cardiac differentiation of human embryonic stem cells(ESCs)in coculturing with human fetal cardiomyocytes.Methods Fetal cardiomyocytes and fibroblasts were obtained from the aborted fetus,and human ESCs were from the inner cell mass(ICM)of the surplus embryos for tube babies,with the treated fibroblast as feeder layer.Human ESCs of passage 2 to 5 were cocultured with fetal cardiomyocytes at the ratio of 1∶2,and the XY chromosome types of these two kinds of human cells were different to each other in order to be marked.At the same time,human ESCs without coculture were used as negative control.The cocultured cells were harvested 5 days later and were double-stained with human XY chromosome probe and cardiac specific antibody(desmin or cardiac troponin I,cTnI).Results On coculture day 5,40%-50% human ESCs expressed cardiac specific antigens,and human ESCs without coculture did not express those antigens.Conclusion Human ESCs could be induced into cardiac differentiation by the coculture with fetal cardiomyocytes,and hopefully they will be the candidate for cell transplantation of heart.

AIM: To investigate the clinic effect of the femoral neck fracture (FNF) with percutaneous internal fixation of hollow screw Ti-nails. METHODS: A total of 57 patients with closed FNF were recruited from Department of Orthopaedics in the First Mine Hospital of Pingdingshan Coal Group from February 2001 to December 2005. They were treated with 3 hollow screw Ti-nails (produce by Shanghai Qunli Medical Devices Co., Ltd) in 5-mm diameter under C-arm X-ray monitoring after close reduction by hand, punctured with 4-6 bone round nails in 2.5-mm diameter through skin for prefixation. The patients were encouraged to stretch and flex muscles early and perform articular physiological movement. The criteria of outcomes: Excellent: the patients were completely cured in six months after surgery, no pain was found in diseased coxa, the articular movement was normal, and they could walk freely half one year after surgey. Good: The fracture was cured in 9 months lately or no healing, there was a little ache in diseased coxa, the articular movement was limited, and they could walk normally in 10-12 months after surgery and recover slight work. Bad: The fractures were not cured, there were absorption, shifting, and aching in fracture joint early, and they need walk with walking stick. RESULTS: There were 55 cases followed up for 9 months, 51 cases for 18 months, and 57 cases for 42 months.①The curative effect of FNF by internal fixation was excellent in 27 cases, good in 20 cases and bad in 10 cases. ②Host response: 6 patients suffered from fracture shift due to screw-nail displacement, 4 patients got bone un-union, 6 patients experienced femoral head necrosis, and 2 patients got ache at bone fracture and were limited for articulation movement. No infection and rejection happened among 57 patients. CONCLUSION: The treatment of AO cannula Ti-screws internal fixation under closed reduction is effective for FNF, and no abnormal biocompatibility between materials and host appears in the clinical follow-up.
