Objective To explore the clinical significance of hydrogen sulfide(H2S)and heme oxygenase-1(HO-1)on pulmonary hypertension(PH),by detecting their levels of patients with congenital heart disease(CHD).Methods Forty-eight patients with CHD who had left-to-right shunt were selected randomly from cardiac surgery in the Fourth Hospital of Hebei Medical University.Forty-eight patients were performed successfully on radical operation under complex intravenous anesthesia,and they were divided 3 groups according to pulmonary artery systolic pressure(PASP)detected by doppler echocardiography before operation:no PH group(PASP0.05).Conclusions H2S plays an important role in the formation of PH and restructure.There is no correlation between PASP and HO-1 activities in serum,but HO-1 may be play an indirect action in the formation of PH and restructure.Measuring the levels of H2S may be a reliable method to follow the change of pulmonary pressure and worsening of PH.

Objective To observe the expression and role of HSP70 in human epidermis and cutaneous neoplasms.Methods 56 cases of epidermis tumors,including 29 biopsy samples from basal cell carcinoma, 27 from squamous cell carcinoma,and 30 from normal human skin were investigated. HSP70 expression was examined by immunohistochemical SABC staining with specific monoclonal antibodies.Results The expression of HSP70 was detectable in the cytoplasm throughout the epidermal cell layers in normal human epidermis,HSP70 expression in the tumor cells in basal and squamous cell carcinomas was reduced (P

Objective: To research the usability of the purpose-in-life test (PIL) for Chinese university students and evaluate the test’s reliability and validity. Methods: 1171 University students were measured by PIL, SCL-90 and Index of Well-being, and 140 University students were retested by PIL. Results: PIL had four factors (life feeling, life goal, life attitude and self-control) which were extracted by factor analysis. The split half reliability was 0.786, the Cronbach ?-co-efficient of PIL and the four factors were 0.878, 0.860, 0.809, 0.270, 0.406 respectively. The test-retest reliability were 0.837,0.849,0.630,0.314,0.728. The scores of Index of Well-being, the total scores of SCL-90 and the factor of depression were used as external criterion;the criterion correlation coefficient were 0.769,-0.504,-0.560 respectively. The correlations between the criterion and the four factors were significant (r=-0.240~0.787, P

Objective To analyze the differences of video laryngoscope, direct laryngoscopy and fibreoptic bron﹣choscope nasal intubation on hemodynamics, inflammatory and stress response. Methods 117 patients underwent surgery from November 2013 to March 2015 were chose as research subjects and randomly divided into video laryn﹣goscope group, direct laryngoscopy group, fiberoptic bronchoscope group based on different cannula enrolled way. Then compared the hemodynamics, inflammation, stress level after intubation among the three groups. Results Com﹣pared with the T0, the three groups patients' systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), C-reactive protein (CRP), interleukin -6 (IL-6), tumor necrosis factor (TNF-α), norepinephrine (NE), plasma cortisol (Cor), angiotensinⅡ(ATⅡ) differences had no significant difference (P>0.05);compared with direct laryn﹣goscopy group, video laryngoscope group, fiberoptic bronchoscope group patients' T1, T2, T3 SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ levels were lower; compared with the video laryngoscope group, optical fiber bron﹣choscopy group patients SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ low levels at T1, T2, T3 were lower (P<0.05). Conclusions Fibreoptic bronchoscope nasal intubation has less influence on patients, will not cause severe stress and inflammatory response, it is one of the ideal instrument anesthesia induction intubation.

Objective To investigate the effect of galectin-3 (Gal-3) on the pathogenesis of primary biliary cirrhosis (PBC).Methods The clinic data of 72 PBC patients at different stages were analyzed and the serum levels of Gal-3 were detected in 72 PBC patients and 20 controls by enzyme linked immunosorbent assay (ELISA).Independent t-test,variance analysis,LSD-t and Pearson correlation analysis were adopted for data analysis.Results The serum Gal-3 levels were significantly higher in PBC patients than those of healthy controls [(855±634) pg/ml,(463±446) pg/ml,P<0.05].With the progression of disease,the levels of Gal-3,platelets,hemoglobin,albumin,IgM and complement C3 gradually declined,but the level of total bilirubin gradually elevated(P<0.05).There was positive correlation between Gal-3 and immunoglobin IgM,complement C3 levels (r=0.330,P=0.005; r=0.357,P=0.002).There was negative correlation between Gal-3 and total bilirubin levels (r=0.350,P=0.003).Conclusion The Gal-3 can participate in the immune-mediated inflammation of PBC and the formation of liver fibrosis.The levels of Gal-3,platelet count,hemoglobin,albumin,IgM,complement C3 and total bilirubin could be regarded as laboratory parameters for the evaluation of the disease severity and prognosis.

Carotenoids play an important role in regulating the hydrogen production of hydrogen-producing Rhodobacter sp. The carotenoids of hydrogen-producing Rhodobacter sp. grown in acetate medium were extracted by using acetone-methanol (7∶2,V/V) solvent and were separated by using thin-layer chromatography on silica-gel plate. The qualitative and quantitative of the carotenoids were analyzed by spectrometry. The results showed that the carotenoids were completely extracted three times with acetone-methanol (7∶2,V/V) in two hours. The ultrasonication had little effect on yield of carotenoids. The yield of carotenoids was 2.81mg/g wet cell. There were 4 spots on the silica-gel plate in the order of yellow, red, light red and light yellow. Yellow spot and red spot were the dominant composition of carotenoid in Rhodobacter sp. The spectrometry data showed that the yellow and red component might be the spheroidene and spirilloanthin respectively.

Objective To determine the effect of bacille Calmette-Guerin-polysaccharide nucleic acid (BCG/PSN)on 2,4-dinitrochlorobenzene(DNCB)-induced atopic dermatitis-like skin lesions in Nc/Nga mice.Methods Fifteen mice were randomly and equally classified into 3 groups,i.e.,control group receiving topical acetone on foot pad and abdomen and intraperitoneal injection of physiological saline,model group receiving topical 5% DNCB solution and intraperitoneal injection of physiological saline,treatment group receiving 5% DNCB solution and intraperitoneal iniection of BCG/PSN,and all drugs were used every other day for 7 weeks.Further more,0.1% DNCB was topically applied on the ear and neck of Nc/Nga mice once a week from week 2 to week 7.The effects of BCG/PSN were evaluated by ear thickness,skin histopathology and immunological parameters.Results Repeated application of DNCB caused the development of eczematous dermatitis in mice.Mice in model group chnieally manifested skin dryness,erythema,edema and erosion with histopathological changes including dermal and epidermal thickening,hyperkeratosis,and inflammatory infiltration.The serum levels of IL-4 and IrE in model group were significantly higher than those in control group[(174.72±12.64)μg/L vs (17.32±3.56)μg/L,(91.49±6.32)ng/L vs (83.95±6.63)ng/L,both P<0.05].Increased serum IL-12 and IFN-γ and decreased serum IgE were observed in treatment group compared with the model group[(122.10±4.64)ng/L vs (20.14±6.15)ng/L(73.89±2.39)ng/L vs (51.53±3.45)ng/L, (84.27±9.35)μg/L vs (174.72±12.64)μg/L, all P<0.05].Conclusion BCG/PSN might be beneficial for the treatment of atopie dermatitis-like skin lesions in Nc/Nga mice by enhancing the secretion of IL-12 and IFN-γ and suppressing the synthesis of IgE.
