Objective To investigate the status of social support and job satisfaction of community nurses and their relationship in Wuhan. Methods A total of 230 community nurses from 20 community health service centers in Wuhan were investigated by general information questionnaire, job satisfaction scale of community nurse and social support scale. Results The total score of job satisfaction was (96.14±14.76) points, the highest score of dimension was leadership and management (23.64±4.60) points, and the lowest was pay and welfare (10.83±3.00) points. The total score of social support was (37.17±7.05) points, the highest score of dimension was perceived social support (20.15 ± 4.48) points, the lowest was availability (8.05±1.57) points. There was a positive association between community nurses′social support and job satisfaction (r=0.248, P<0.05). Conclusions Social support is one of the predictors of job satisfaction. In order to make sure the sustainable development of community health services, it is necessary to know the status and take corresponding measures to improve the levels of social support and job satisfaction.

Objective To study effects of tethered spinal cord on functions of bladder and urethra. Methods Thirty six patients with tethered spinal cord were evaluated by video urodynamic studies. Filling phase function of bladder was evaluated by compliance of bladder and the presence of vesicoureteral reflux; voiding phase function of bladder was evaluated by maximal detrusor pressure; the synergy between detrusor and external urethral sphincter and continence of urethra were evaluated by voiding study with synchronous X ray image and pressure flow plot. Results 50% patients was diagnosed as detrusor areflexia with low compliance bladder, which was the main type of neurogenic bladder for patients with tethered spinal cord. And 22% was diagnosed as detrusor hyperreflexia. The incidence (83%)of damage of kidney function in patients with detrsusor areflexia and low compliance was significantly higher than patients with detrusor hyperreflexia ( P

Objective To evaluate effects of acitretin on HaCaT cells cultured in hypoxic condition,and to preliminarily explore the possible therapeutic mechanisms of acitretin in psoriasis.Methods HaCaT cells were divided into several groups to be cultured in hypoxic condition with the presence of acitretin at concentrations of 10-5,10-6,10-7 and 10 8 mol/L respectively,with cells treated with dimethyl sulfoxide (DMSO) as DMSO control group and those receiving no treatment as blank control group.Cellular proliferative activity was evaluated by CCK-8 assay after 12-,24-and 36-hour hypoxic culture in vitro.The mRNA and protein expressions of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) were determined by reverse transcription (RT)-PCR and Western-blot analysis,respectively,after 24-hour hypoxic culture.Results After 24-hour hypoxic culture,the cellular proliferation rate was inhibited by 13.31％ ± 1.15％,21.86％ ± 5.31％,32.05％ ± 2.99％ and 37.28％ ± 3.21％ in the 10 8-,10-7-,10-6-and 10-5-mol/L acitretin groups respectively.With the increase of culture duration and acitretin concentrations,the degree of inhibition on cellular proliferation increased gradually.Compared with the blank control group,the 10-5-mol/L acitretin group showed significantly decreased protein expression of HIF-1α (0.319 ± 0.180 vs.1.196 ± 0.088,P ＜0.05),as well as decreased mRNA and protein expressions of VEGF (mRNA:0.442 ± 0.090 vs.1.108 ± 0.073;protein:0.216 ± 0.066 vs.1.174 ± 0.186;both P ＜ 0.05).However,no significant difference was found in the mRNA expression of HIF-lα between the 10-5-mol/L acitretin group and blank control group.Conclusion Acitretin can suppress the in vitro proliferation of HaCaT cells cultured in hypoxic condition,and down-regulate the expressions of HIF-1α and VEGF proteins as well as VEGF mRNA.

Objective To observe the effect of early intervention on motor and mental development in premature infants. Methods 108 cases of hospital-born premature infants were divided into early intervention group (n=57) and control group (n=51). All the cases accepted conventional treatment and health-care, and the intervention group accepted the early intervention in addition. They were assessed with psychomotor development index (PDI) and mental development index (MDI) of Bayley Scales of Infant Development when they were 1 or 2 years old. The incidence of cerebral palsy when they were 2 years old were recorded. Results 2 cases (1 for each) lost during the follow-up.The PDI and MDI were more in the intervention group than in the control group (P<0.05), both as the 1 and 2 years old. The incidence of cerebral palsy was less in the intervention group than in the control group (P<0.05). Conclusion The early intervention can promote mental and motor development in premature infants, and reduce the incidence of cerebral palsy later.

Objective To calculate the effects of thermoplastic mask on X-ray surface dose.Methods The BEAMnrc Monte Carlo Code system, designed especially for computer simulation of radioactive sources, was performed to evaluate the effects of thermoplastic mask on X-ray surface dose.Thermoplastic mask came from our center with a material density of 1.12 g/cm2. The masks without holes,with holes size of 0. 1 cm× 0. 1 cm, and with holes size of 0. 1 cm × 0. 2 cm, and masks with different depth (0.12 cm and 0.24 cm) were evaluated separately. For those with holes, the material width between adjacent holes was 0. 1 cm. Virtual masks with a material density of 1.38 g/cm3 without holes with two different depths were also evaluated. Results Thermoplastic mask affected X-rays surface dose. When using a thermoplastic mask with the depth of 0. 24 cm without holes, the surface dose was 74. 9% and 57.0% for those with the density of 1.38 g/cm3 and 1.12 g/cm3 respectively. When focusing on the masks with the density of 1.12 g/cm3, the surface dose was 41.2% for those with 0.12 cm depth without holes;57.0% for those with 0. 24 cm depth without holes;44. 5% for those with 0. 24 cm depth with holes size of 0.1 cm ×0.2 cm;and 54.1% for those with 0.24 cm depths with holes size of 0.1 cm ×0.1 cm.Conclusions Using thermoplastic mask during the radiation increases patient surface dose. The severity is relative to the hole size and the depth of thermoplastic mask. The surface dose change should be considered in radiation planning to avoid severe skin reaction.

Objective To investigate the production of carbapenemase and 16S rRNA methylase in five isolates of pan-drugs resistant E.cloacae recovered in Ruijin hospital.Methods MICs of the five isolates to 10 antibiotics were determined by E test.Six kinds of 16S rRNA methylase genes and a series of β- lactamase genes were amplified by PCR.Shotgun cloning was performed to detect carbapenem resistance determinant.The conjugal transfer of carbapenemase gene and 16S rRNA methylase gene was performed in broth culture with E.coli J53 as the recipient.Pulsed-field gel electrophoresis (PFGE) was carried out to analyse the genotyping.IEF was performed to detect β-1actamases.Southern blot was performed to determine the location of carbapenem resistance determinant.Results The MICs of 10 antibiotics were ＞32 mg/L.Four β-1actamases with pIs of 5.4 ( TEM-1 ),6.7 ( KPC-2 ),8.2 ( SHV-12 ),8.4 (CTX-M-14) were determined.The insertion sequence in the recombinant plasmid was blaKPC-2 flanked by a transposon.blaKPC-2 was located on a large non-conjugative plasmid whereas armA was located on an other conjugative plasmid.PFGE patterns of 5 isolates were identical.Conclusion KPC-2 was responsible for carbapenem resistance in pandrugs resistant Enterobacter cloacae.There was no relationship between blaKPC-2 and armA.Although pandrug resistant Enterobacteriaceae remain rare,the emergence of this group of organism merits monitoring.

Objective To investigate the effect of scalp acupuncture on cerebral blood flow and gross motor function in children with spastic cerebral palsy. Methods From January to November, 2016, 79 children with spastic cerebral palsy were randomly divided into con-ventional group (n=40) and scalp acupuncture group (n=39). Both groups received conventional rehabilitation treatment, and the scalp acu-puncture group was given scalp acupuncture in addition, for five months. The systolic blood flow velocity (Vs), mean flow velocity of cere-bral artery (Vm) and vascular resistance index (RI) of anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) before and after treatment were assessed with color transcranial Doppler ultrasound (TCD). The clinical effect was evaluated with the Gross Motor Function Classification System (GMFCS). Results Five cases dropped out during the follow-up, three cases in the con-ventional group and two cases in the scalp acupuncture group. There was no significant difference in all the indexes between two groups be-fore treatment (P>0.05). After treatment, the Vs and Vm of ACA, MCA and PCA improved (t>2.051, P<0.05), no improvement was found in the RI of ACA, MCA and PCA in the conventional group (t<1.1631, P>0.05), and they decreased in the scalp acupuncture group (t>2.659, P<0.05). After treatment, the Vs and Vm of ACA, MCA and PCA were higher in the scalp acupuncture group than in the conventional group (t>2.098, P<0.05), the RI of ACA was lower in the scalp acupuncture group than in the conventional group (t=2.375, P<0.05), and no signifi-cant difference was found in the RI of MCA and PCA between two groups (t<1.637, P>0.05). The total effective rate was higher in the scalp acupuncture group than in the conventional group (χ2=6.887, P<0.05). Conclusion Scalp acupuncture facilitates to increase the cerebral blood flow, decrease the vascular resistance, and improve gross motor function in children with spastic cerebral palsy.
