Objective To investigate autonomic nervous system(ANS)function of hyperthyroidism and hyperthyroidism by analyzing the heart rate variability(HRV)of patients with the diseases.Methods 12-synchronous dynamic 24-hour monitoring and man-machine dialogue were performed in 49 patients with hyperthyroidism,25 patients with hypothyroidism and 40 controls after removing interference,and 24-hour electrocardiogram wag analyzed.Heart rate variability indicators observed included 24-hour time-domain indexes[standard deviation of all experimental time RR(SDNN),root of mean square standard deviation from adjacent RR interval(RMSSD)]and 24-hour frequency domain indicators[very low frequency power(VLF),low-frequency power(LF),high frequency power(HF),low frequency power/high frequency power(LF/HF)].Results Indicators of time domain in hyperthyroidism group,such as SDNN[(69.65±13.55)ms]and RMSSD[(12.98±3.20)ms]were obviously lower than those of the control group[(136.07±11.95),(29.70±5.85)ms],the differences being statistically significant (P＜0.01).Indicators of frequency domain HF[(5331±15.84)msz]were lower than those of the control group [(223.38±50.09)ms2],butVLF[(1823.55±238.13)ms2],LF[(501.88±92.47)ms2]and LF/HF(5.89±1.15)was higher compared with that in the control group,repectively[(325.68±60.47)ms2,(405.60±5 1.41)ms2,2.14±0.56,P＜0.01).Among time domain indicators in hypothyroidism group,SDNN[(77.00±15.48)ms]and RMSSD [(14.80±2.58)ms]were also obviously lower than those in the control group(P＜0.01),the difference being significant statistically(P＜0.01).Frequency domain index HF[(57.88±12.20)ms2],VLF[(251.48±24.67)ms2],LF[(128.68±43.78)ms2]also obviously lower than those in the control group(P＜0.01),but LF/HF,being 1.83±0.63,was in a normal range and did not significantly changed(P＞0.05). Conclusion In patients with hyperthyroidism both sympathetic and vagus nerves are hyperdynamic,while in patients with hypothyroidism,vagus nerves are hyperdynamic,while sympathetic nerve hypodynamic.

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.

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.

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.

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.
