Objective To observe the expression of novel URB gene in the differentiation display of 3T3-L1 preadipocytes and the effects of interleukin-6 (IL-6) and pioglitazone (PIO) on URB mRNA expression in 3T3-L1 adipocytes at different times. Method The 3T3-L1 adipocytes were treated with IL-6 and PIO under different concentration and different time phase, and real-time fluorescence monitoring RT-PCR was conducted to measure the URB mRNA level. Fat droplets were verified by oil red O staining. Results 1. URB mRNA level was increased gradually in the whole differentiation process. 2. The expression levels of URB mRNA was decreased along with the treatment of IL-6 in a dose-dependent manner in 3T3-L1 preadipocytes and adipocytes. 3. PIO increased the level of URB mRNA in 3T3-L1 adipocytes, and the reducing effect of IL-6 on URB mRNA could be corrected by PIO. Conclusion URB may be an important adipocytokin which affects energy metabolism and may work as a pharmacological gene target in the future.

Objective To verify the presence of anti-ovary antibodies in systemic lupus erythematosus (SLE) and its possible correlations with serum levels of hormone profile and menstrual disturbances in patients with SLE.Methods Clinical data of 78 consecutive paticnts who fulfilled 4 or more of the ACR 1997 revised criteria for SLE were studied and compared with 40 age-matched healthy controls,including anti-ovary antibodies.Results 27 (34.6％ ) patients with SLE,and 1 (2.5％) of the healthy controls tested positive of anti-ovary antibodies.The levels of E2 and T and P decreased[ E2:( 80.96 ± 36.2 ) ng/L vs ( 118.53 ± 42.4 ) ng/L; T:( 3.85 ± 1.18 ) nmol/L vs ( 6.43 ± 2.28 ) nmol/L; P:( 1.37 ± 0.59 ) μg/L vs ( 3.92 ± 1.23 ) μg/L],and the levels of FSH and LH and PRL increased in SLE patients when compared with healthy controls [ FSH:( 19.17 ± 9.26)IU/L vs (10.18 ±7.27 )IU/L; LH:( 21.19 ± 12.44)IU/L vs (13.79 ±8.27)IU/L;PRL:(6.18 ± 2.27 ) μg/L vs (2.37 ±0.63)μg/L,P ＜0.05 orP ＜0.01].The higher SLEDAI score,higher rate of menstrual disturbances (6.3 ±2.8 vs 3.5 ± 1.7,81％ vs 47％,P ＜0.05 or P ＜ 0.01 ) and decreased serum level of E2 [ (64.13 ± 26.36 ) ng/L vs ( 82.83 ± 28.71 ) ng/L,P ＜ 0.05 ]were found in SLE patients with anti-ovary antibodies positive than in SLE patients with anti-ovary antibodies negative.Conclusions The presence of anti-ovary antibodies was 34.6％ in SLE,and may correlate to decreased serum level of E2 and menstrual disturbance.

Objective To investigate the effects of self-efficacy-oriented nursing intervention on postoperative quality of life of lung tumor patients. Methods Ninety patients with lung tumors undergoing chest surgery in our hospital from March 2010 to March 2012 , involved in the study. The nursing data were retrospectively analyzed for investigation of the nursing strategies. The patients were randomized into two group with random digits table in equal number: The control group received routine nursing and the intervention group with self-efficacy-oriented nursing intervention beside routine nursing care. 3 months after nursing intervention , the two groups were compared by Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) in terms of quality of life and psychological state. Results The scores of the intervention group by SDS and SAS were both significantly higher than those of the control group (P < 0.05). The scores of the intervention group on self efficacy and quality of life were significantly higher than those of the control (P < 0.05). Conclusion The self-efficacy-oriented nursing intervention applied in the postoperative nursing care to lung cancer patients can significantly improve the postoperative symptoms and psychological status. It can also improve their self efficacy and then enhance their quality of life.

Objective To investigate the forming mechanism of smile anatomically,and to analyze the changes of aging characteristics of mid-lower face.Methods Ten (with 20 sides) adult fresh cadaveric heads were fixed by formalin,and then nasolabial fold morphology was observed under 10X operating magnifying glass,and compared with alteration of the middle and lower face aging features under the state of smiling and static according to observation from 50 doctors' and out-patients' photos.Results The nasolabial fold was the boundary between fatty and fat-free zone in the middle face,the lateral side of which was malar fat pad.The nasolabial fold was the linear area,which was formed by the insertions of seven mimetic muscles on the skin.When smiling,the nasolabial fold and cheek groove,got deep and extended,cheek stripe became obvious.While smiling,malar fat pad shifted up,and tear trough became deformity..64％ disappeared and 36％ getting shallow and appearance improved; orbit-malar fold showed 100％ horizontal part disappeared,74 ％ vertical part became shallow and improved,and 26％ stayed stable; mid-cheek fold showed 78％ dissovled,22％ getting shallow and improved; Labiomandibular fold showed 100％ Ⅲ degree disappeared,100％ Ⅱ degree dissovled,74％ Ⅰ degree disappeared,and 26％ getting shallow and ameliorated; submaxilla line showed 18％ getting smooth and 82％ remained.Conclusions Smiling is produced by movement of mimetric muscles,and its orgin is from nasolabial fold.A smile could make malar fat pad upwards to mask some aging characteristics of middle and lower face,which is helpful to form a younger face.

Objective To investigate the diagnostic accuracy of 13C urea breath test (13C-UBT)in the diagnosis of Helicobacter pylori (Hp) infection in patients with gastric remnant.Methods A total of 94 gastric remnant patients (gastric remnant group) and 100 non-gastric remnant patients (control group) received 13C-UBT.According to the course of the disease,the gastric remnant group were divided into group 1 (29 cases,≤5 years),group 2 (33 cases,6 to 10 years) and group 3 (32cases,＞10 years).Before surgery,the diagnosis of Hp infection was according to 13C-UBT and gastric mucosa tissue staining.After surgery,the diagnosis was according to gastric mucosa tissue staining.The applying value of 13C-UBT in gastric remnant patients was evaluated.The consistency of results between 13C-UBT and gastric mucosa tissue staining were evaluated by the Kappa test.Results In gastric remnant group,the Hp infection rate after surgery (37.2％) was obviously lower than that before operation (79.8％;x2 =35.058,P＜0.01) and that of control group (77.0％).After surgery,the Hp infection rate of patients with Billroth Ⅱ gastrectomy (24.4％) was lower than that of patients with Billroth Ⅰ gastrectomy (47.2％ ; x2 =5.133,P=0.023).Before surgery,the Hp infection rate of gastric remnant subgroups were similar (P＞0.05).With the extension of the postoperative course,the Hp infection rate gradually decreased in gastric remnant subgroups (group 1:58.6％,group 2:36.4％,group 3:18.8％; x2=7.839,P=0.021).Setting the cut-off point at 2.0‰ in the gastric remnant group and 3.5‰ in the control group,the accuracy rate of diagnosis was the highest (92.6％ and 96.0％).There was good consistency between the results of 13C-UBT and gastric mucosa tissue staining (Kappa =0.84,P＜0.01).Conclusion With suitable operation and standard,13C-UBT may be a easy,safe and effective assay applied in the gastric remnant patients.

BACKGROUND:Constant magnetic field of proper intensity can inhibit the proliferation of vascular smooth muscle cells,and it can be used to inhibit the restenosis following percutaneous coronary intervention.OBJECTIVE: To observe the effect of constant magnetic field of different intensities on the expression of osteopontin gene in rat aorta smooth muscle cells, so as to investigate whether magnetic field can be used to prevent and treat restenosis following percutaneous coronary intervention.DESIGN: A randomly grouping and controlled observation.SETTING: Department of Cardiology, Xijing Hospital of the Fourth Military Medical University of Chinese PLA.MATERIALS: The experiments were carried out in the laboratory of Department of Cardiology (Military Institute of Cardiovascular Disease), Xijing Hospital of the Fourth Military Medical University of Chinese PLA from February to December in 2006. Male pure SD rats of 200-250 g were used.METHODS : Rat aorta smooth muscle cells were cultured in vitro in DMEM medium containing fetal bovine serum (0.1 in volume serum), and then the cells were randomly divided into control group, constant magnetic field of 1, 5, 10 and 50 Gs groups, those in the control group were not treated with magnetic field, and those in the other groups were treated with magnetic field and cultured for another 48 hours. Reverse transcription-polymerase chain reaction and Western blotting were combined with absorbance (A) scanning analysis to observe the effect of constant magnetic field on the expressions of osteopontin and its mRNA in smooth muscle cells.MAIN OUTCOME MEASURES: Expressions of osteopontin and its mRNA in smooth muscle cells.RESULTS: The expressions of osteopontin and osteopontin genes in the constant magnetic field groups were significantly decreased as compared with that in the control group (P ＜ 0.05), there were also significant differences among the constant magnetic field groups of different intensities (P ＜ 0.05). It was indicated that the stimulation of constant magnetic field was in an intensity-dependent manner, and the expressions of osteopontin and osteopontin mRNA were enhanced as the intensity of magnetic field was increased.CONCLUSION: Constant magnetic field of proper intensity can inhibit the osteopontin expression in vascular smooth muscle cells on the gene level, and magnetic field may play a role in preventing and treating the restenosis following percutaneous coronary intervention.
