ObjectiveTo investigate the status of job satisfaction and the influencing factors of the disabled in order to know their employment quality.Methods79 disabled employees of one company in Hunan province were randomly interviewed with Minnesota Satisfaction Questionnaire.ResultsThe overall satisfaction scores of 74 disabled workers was 67.78, which inner satisfaction was better than external satisfaction. The most satisfied was job independence and colleagues' relationships and the most unsatisfied was work flexibility and conditions. There were statistically significant differences between gender, age, disabled species and job satisfaction. In personal level, most influencing factors of disabled job satisfaction were gender, age, disability and salary types.ConclusionVocational rehabilitation such as the high-risk population could be performed specifically on the basis of the job satisfaction survey.

BACKGROUND:Hyperbaric oxygen(HBO)treatment promotes the proliferation and differentiation of endogenous neural stem cells in neonatal rats following hypoxic/ischemic brain damage(HIBD).The Wnt signaling pathway is associated with neurogenesis.However,there are few data recording the role of HBO in the differentiation of neural stem cells in vitro.OBJECTIVE:To observe the effect of HBO on differentiation and Wnt3 expression of bone marrow mesenchymal stem cells(BMSCs).METHODS:BMSCs were isoiated and cultured.The rat BMSCs of passages 3-5 were cultured in DMEM/F12(1:1)medium with basic fibroblast growth factor,epidermal growth factor and B27 for 24 hours.The induced BMSCs were randomly divided into two groups:control group(no treatment)and HBO group(HBO,0.10 MPa,60 minutes stabilizing pressure with at least 90% oxygen).The neuron specific encloase(NSE),glial fibrillary acidic protein(GFAP)and 04 marked oligodendrocyte immunocytochemistry were detected by immunofluorescent staining,and Wnt3 protein expression was detected by Western-blot.RESULTS AND CONCLUSION:BMSCs cultured in classic medium of neural stem cells could significantly induce the expression of nestin.The expression of NSE and 04 of HBO group was greater than control group(P＜0.01),but GFAP expression displayed no significant difference between the groups(P＞0.05).Western blot showed HBO could enhance the Writ3 expression (P＜0.05).Results show that HBO can induce BMSCs to differentiate into neural cells and oligodendrocyte,which is correlated with the activation of the Wnt3 protein.

Objective To investigate the expression of Fascin in early-stage NSCLC, evaluate the relevance between Fascin expression level and prognosis.Methods The immunohistochemistry method was used to assess the expression of Fas-cin in 111 lung cancer FFPE tissues with stage Ⅰ and Ⅱ NSCLC.The relationship between Fascin expression and the clinico-pathological characteristics was analyzed.The prognostic significance of Fascin expression was evaluated with Kaplan-Meier sur-vival analysis.Results In the early-stage of NSCLC, the positive rate of Fascin expression was 64.8%, no expression in the paracarcinoma tissue.The positive rate of squamous cell carcinoma was 78.7% and was significantly higher than that in adeno-carcinoma 48.0%(P<0.01).Whether in squamous cell carcinoma or adenocarcinoma group, the expression of Fascin was correlated significantly with lymph node metastasis tumor stages and DFS(P<0.05).And the positive expression of Fascin was an independent risk factor of poor prognosis for patient with NSCLC .Conclusion Fascin is expected to be a biomarker for the prognosis of patients with early-stage NSCLC.

Objective To analyze the correlation between the dry eye symptom and signs in middle-aged and aged people by Lipiview(R) ocular surface interferometry.Methods A total of 170 eyes from 85 middle-aged and aged people (55-80 years old) were examined with Standard Patient Evaluaion of Eye Dryness(SPEED) questionnaire and Lipiview(R) ocular surface interferometry,meanwhile obtaining the consent of the subjects.Then the correlation between the symptom and Lipid Layer Thinckness (LLT) and partial blink rate were analyzed.Results SPEED questionnaire score was 6.13 ±4.60.LLT was(74.88 ± 21.16) nm.LLT variability was 4.47 ± 3.40.The partial blink rate was 0.62 ± 0.36.The Spearman correlation analysis indicated that the nega-tive correlation was shown between the SPEED questionnaire score and LLT (r =-0.823,P =0.000),SPEED questionnaire score and LLT variability(r =-0.268,P =0.018).The positive correlation were found between LLT and Std.Dev of LLT (r =0.339,P =0.030).However,the results of the SPEED score were uncorrelated with partial blink rate (P ＞ 0.05).Conclusion The results from this study demonstrate that correlation among symptom,LLT and LLT variability,but poor correlation between symptom and partial blink rate.

Objective To explore the correlation between plantar pressure and walking function in hemiplegic stroke patients.Methods Thirty hemiplegic patients with stroke (a hemiplegic group) and thirty age-matched healthy persons (a control group) were recruited.Gait and balance function training and assessment system (model:AL-600) were used to quantify the walking velocity,peak plantar pressure at heel-strike and push-off periods and displacement of center of pressure (DCOP) of all subjects during walking.The asymmetry of gait was calculated.Two independent sample t-test were used to compare the walking velocity,peak plantar pressure and DCOP for the two groups.Pearson correlation coefficients were applied to analyze the correlation between the walking velocity and peak plantar pressure and DCOP.Results The walking velocity,the peak plantar pressure at heel-strike and push-off periods and DCOP of the hemiplegic group were significantly lower than the control group.In the hemiplegic group,the asymmetry of peak plantar pressure and DCOPx significantly increased,while that of DCOPy became bigger without significant difference.Moreover,the walking capacity of the hemiplegic group was positively correlated with the peak plantar pressure and DCOP.Conclusion Among hemiplegic stroke patients,both the peak plantar pressure at heel-strike and push-off periods lower in a way.Their capacity of weight transfer decreases,which is closely related to their walking velocity.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.
