Objective:To compare the sleep behaviors and the coping styles between chronic insomniacs and normal sleepers.Methods:The self-made questionnaire of sleep behaviors (including the irrational beliefs and attitudes toward sleep, the dysfunctional sleep behaviors and anxiety on evening),the coping styles and the internal-external locus of control(I-E) score were administered to 62 chronic insomniacs and 62 normal sleeper matched by age and sex.Results:The irrational beliefs and attitudes toward sleep, the dysfunctional sleep behaviors, the anxiety on evening, and the scores of I-E and of the self-blame in coping style were higher in the chronic insomniacs than in normal controls. The scores of problem-solving of the chronic insomniacs were lower than that of the normal controls. Regression analysis indicated the irrational beliefs about sleep and the dysfunctional sleep behaviors were associated with problem-solving and I-E scores.Conclusions:Chronic insomnia group has irrational beliefs and attitudes toward sleep, they have more dysfunctional sleep behaviors and higher anxiety on evening. Their ability of problem-solving is impaired and they incline to attribute their fate to external control.

Hypoxia-induced factors(HIFs)are the main regula-tors for the response of hypoxic environment.They are involved in hypoxia-related lung tissue cell damage and abnormal cell pro-liferation,among which,HIF-1αand HIF-2αplay the most im-prominant roles.This paper reviews the current researches of HIF-1αand HIF-2α,focusing on their structural and functional similarities and diversities,as well as their roles in the patho-genesis of hypoxic pulmonary hypertension.

The quality and quantity of published SCI papers written by the Third Military Medical University from 2010 to 2012 were analyzed to provide information for the scientific research administration.The problems of assessment with SCI was discussed.At last,suggestions were proposed to improve scientific research administration,innovation ability and scientific and technological level.

Objective To establish the HPLC fingerprint of Eupatorium chinense.Methods The ana-lysis was performed on a Kromasil C18 column(250 mm?4.6 mm,5 ?m) with acetonitrile-water as mobile phase in a gradient mode.The flow rate was 1.0 mL/min.The column temperature was 25 ℃ and the detection wavelength was 230 nm.Results The fingerprint of E.chinense with common 13 peaks was established.The relative retention time and the ranges of relative area of the common peaks were determined.Conclusion The established fingerprint could be used for the quality control of E.chinense.

Purpose To explore the value of spectral CT imaging in differentiating pancreatic carcinoma and mass-forming pancreatitis, and to improve the preoperative diagnosis accuracy. Materials and Methods The dual-phase spectral CT imaging data in patients with pathology-proven pancreatic carcinoma (n=62) and mass-forming pancreatitis (n=30) were retrospectively analyzed. At 40-140 keV (with 10 keV increment), the mean CT values, energy spectrum curves and iodine concentrations were measured and compared between pancreatic carcinoma and mass-forming pancreatitis in arterial phase and portal venous phase. Results The mean CT values of mass-forming pancreatitis at 40-140 keV were higher than pancreatic carcinoma in both arterial phase and portal venous phase with significant difference (t= -7.349- -4.810, P<0.05; t= -6.760- -5.496, P<0.05). The energy spectrum curves were significantly different between pancreatic carcinoma and mass-forming focal pancreatitis, especially at 40-70 keV. The iodine concentrations of pancreatic carcinoma were lower than mass-forming pancreatitis in arterial phase and portal venous phase with significant difference (t=-28.577, P<0.05; t= -28.451, P<0.05). Conclusion Pancreatic carcinoma and mass-forming pancreatitis can be differentiated by measuring the CT value at different energies, energy spectrum curves and iodine concentrations.

Full ceramic prosthesis is becoming the main prosthetic development direction. As an important kind of full ceramic prosthesis, full ceramic veneer has not only natural cosmetic appearance and perfect biocompatibility, but also can preserve tooth structure as much as possible, which would be more easily accepted by patients for cosmetic prosthesis. Many methods, such as slip casting, die casting and CAD/CAM technology are available to make full ceramic veneer. All the methods have their own advantages and disadvantages. Slip casting is easy to be developed widely with low cost, so be used in practical work. In this article, the working process of full ceramic veneer, especially manufacture of removable dies, duplication of refractory models, were introduced, which was supposed to be beneficial for the technicians.

Objective: To investigate the role of Smads signaling pathway in the transdifferentiation of airway epithelial cells into myofibroblasts induced by rhTGF-?1 in vitro.Methods: We exposed cultured 16HBE cells to rhTGF-?1(10?g/L),detected the levels of Phosphorylated Smad2 and Smad3 in nucleus proteins by Western blot at different time points,treated with rhTGF-?1 the 16HBE cells pre-transfected with either the expression plasmid of Smad7(pCDNA3.0/Smad7) or the blank vector(pCDNA3.0),and determined the expression of ?-SMA by immunofluorescent staining and RT-PCR and that of E-cadherin by RT-PCR.Results: The expression of Phosphorylated Smad2 was observed and that of Smad3 increased in the TGF-?1-treated group,with the levels of Phosphorylated Smad2 and Smad3 elevated in a time-dependent manner.The level of ?-SMA was significantly decreased while that of E-cadherin markedly increased in the Smad7 transfection group as compared with the blank vector transfection group 24 h after TGF-?1 stimulation,and no differences were found between the two groups at 36 h.Correspondingly,the number of ?-SMA-positive cells was reduced in the Smad7 group compared with the blank vector group(P

Aim To investigate whether rosuvastatin induced reduction of atherosclerotic plaque was related to the expression of Sialyltransferase ( ST6 Gal-Ⅰ) in ApoE-/ - mice. Methods Six-weeks old ApoE-/ -mice fed with high fat were divided randomly into three groups: baseline group ( n=12 ) , control group ( n=12 ) and rosuvastatin group ( n =12 ) . Sixteen weeks later, control group was sacrificed. Serum and aortic intima were saved. Control group and rosuvastatin group were fed for seven weeks continually. Concentra-tions of serum lipids(TC, TG, LDL and HDL) were analyzed. Sections from the aortic root were examined by Hematoxylin-Eosin( HE) staining. The size of ath-erosclerotic lesion in each section was evaluated. Ex-pression of ST6 Gal-Ⅰ in aortic intima was detected by immunohistochemistry. Results Plasma TG and LDL-C, plaque areas and intimal thickness of control group were significant higher than those of baseline group ( P<0. 05 ) . Those results indicated that the AS model was successfully constructed. After seven weeks, the plaque areas and concentrations of serum lipids of rosu-vastatin group were obviously smaller than those of con-trol group(P<0. 05). The expression of ST6Gal-Ⅰin aortic root was decreased in control group compared to the baseline, and which was increased in control group compared to the rosuvastatin group. Conclusion Ro-suvastatin could inhibit the progression of atherosclero-sis, which might be related to the expression of ST6Gal-Ⅰ in aortic root.
