Objective To investigate the changes of stress response on inhalation-intravenous general anesthesia during pericystectomy for Liver hydatid cyst. Methods Thirty ASA I-II patients with liver hydatidosis for pericystectomy were studied. The blood from right jugular vein were collected for measurement of serum cortisol (Cor) concentrations and glucose (BG) levels, and MAP, HR and BIS were observed and recorded at different point-times: pre-intubation for 1 min, post-intubation for 3 min, pre-incision for 1 min, post-incision for 3 min, post-incision for 10 min, post-surgical exploration 10 min. The data of pre-intubation and pre-incision served as controls. Results The levels of Cor concentration of post-incision for 10 min were decreased than those of pre-intubation and pre-incision (P<0.05); MAP of post-incision for 10 min and post-surgical exploration for 10 min were increased than those of pre-intubation and pre-incision (P < 0.01); For HR, the data of post-surgical exploration 10 min was much quicker compared with pre-incision (P < 0.01), which is slower than that of pre-intubation(P<0.01). Conclusion Inhalation-intravenous general anesthesia may inhibit the stress response during intubation,incision and surgical exploration for liver hydatidosis pericystectomy. Hemodynamic changes during incision may reflect the trend of stress response in advance.

In order to induce heavy Pneumocystis pneumonia, rats were treated with dexame-, thasone twice a week for 14 weeks. Mature cysts, immature cysts and ruptured cysts were, identified on lung imprints. By phase-contrast microscopy mature cysts were spherical in, shape containing intracystic bodies both spherical and irregular, small to large trophozoites having polymorphic shapes, one nucleus and many vacuoles. Elcctro-microscopically, large amount of irregular trophozoites adhered to the surface of the type I alveolar epithelial cells in the alveolar cavity were observed. The above histological findings were typical features of Pneumocystis pneumonia (Figs. 1-8).

Objective To observe the vasodilation effect of extract of Jasminum samba (EJs), a kind of traditional Chinese medicine, on ex vivo rat thoracic aortic rings, and to investigate its mechanism. Methods On ex vivo aortic ring perfusion device, influence of EJs on contraction of the aorta induced by phenylephrine (PE) or potassium chloride (KCl) was observed. Influence of N-nitro-L-arginine-methylester ( L-NAME ), barium chloride ( BaCl2 ), glibenclamide ( Gli ) on vasodilating effect of EJs (0. 5, 1, 2, 4, 8 g·L-1 ) was detected. Effect of EJs on the contraction of calcium chloride (CaCl2 ) and PE in Ca2+-free medium was detected. [ Ca2+ ] i in vascular smooth muscle cells was determined by using laser scanning confocal microscope (LSCM). Results In blood vessels with intact endothelium, EJs concentration-dependently decreased PE- or KCl-induced vasoconstriction, the maximum dilating effect being (105. 0±3. 2)% and (78. 0±6. 5)% , respectively; L-NAME affected the vasodilatory effect of EJs on thoracic aorta rings ( P<0. 01), the maximum dilatory effect being (58. 0 ± 6. 9)% . BaCl2 and Gli had significant influence on vasodilation of EJs, and the contraction was obviously attenuated (P<0. 01), the maximum dilatory effect being (37. 0±5. 2)% and (78. 0±10. 0)% , respectively. EJs significantly inhibited contracting effect of PE on thoracic aorta rings in Ca2+-free medium (P<0. 01). The maximum contraction effect was (70. 0±6. 3)% . EJs inhibited CaCl2-induced vasoconstriction (0. 5-8 mmol·L-1 ), and vasoconstriction was decreased by (65. 0±3. 2)% . LSCM recorded that Fmax / F0 of 4 and 8 g·L-1 EJs was (2. 0±0. 2) and (1. 5±0. 2), respectively. Conclusion EJs exerted a dose-dependent vasodilating effect on rat isolated aorta rings. The mechanism might be related to promoting NO release, activating K+channels and decreasing the concentration of cytoplasmic Ca2+.

Conclusion In order to reduce the rate of birth defects and improve the quality of births, we should implement three-level prevention education system, enrich the health education methods to enhance the knowledge, attitude and behavior of married women.

Objective To investigate the role of Twist and vascular endothelial growth factor (VEGF)in the development of epithelial ovarian cancer and their relationship with clinical pathological features.Methods The expressions of Twist and VEGF were detected by immunohistochemical staining (SP)method in 80 cases of epithelial ovarian cancer and 10 paired cases of normal ovarian tissue.Results In the 80 cases of ovarian cancer tissues,the positive expression rate of Twist and VEGF in epithelial ovarian cancer was 85% and 86.25%,respectively,which were remarkably higher than those in normal ovarian tissues (P <0.01).The expressions of Twist and VEGF were closely associated with clinical stages,pathological grades and lymph node metastasis,but not correlated with age or pathological patterns (P >0.05).There was a significant correlation between the expressions of Twist and VEGF in epithelial ovarian cancer (r =0.646,P <0.01).Conclusion The high expressions of Twist and VEGF may play a potential role in the occurrence,development and invasion process of epithelial ovarian cancer.

Objective To explore the relationship of stromal derived factor 1α (SDF-1α) and CD44variant isoforms (CD44v6) with progress of multiple myeloma (MM). Methods Bone marrow mononuclear cells(MNCs) and bone marrow stromal cells (BMSCs) from 24 cases of MM patients (14 cases of untreated and relapsed and 10 cases of stable MM patients) and 15 cases of subjects were investigated as potential SDF-1αand CD44v6 product. The level of SDF-1α and CD44v6 of the conditioned media from MM patients and subjects were analyzed by ELISA. Results The level of SDF-1α and CD44v6 from MNCs in untreated and relapsed MM patients [(7232.41 ± 2644.97) pg/ml and (34.34 ± 13.20) ng/ml] were significantly higher than stable MM patients [(2315.49 ± 748.29) pg/ml and (15.69 ± 5.28) ng/ml] (t =6.25, t= 7.82, P ＜0.05) and 15 subjects [(1149.52 ± 636.06) pg/ml and (4.85 ± 3.62) ng/ml] (t= 4.60, t = 7.61, P＜ 0.05). The level of SDF-1α in stable MM patients was different from healthy subjects (P ＜0.05), but the level of CD44v6 in stable MM patients was not different from controls. The level of SDF-1α and CD44v6 in stable MM patients were significantly higher than health subjects (t = 2.99, t= 4.87, P ＜0.05). The level of SDF-1α was also detected from BMSCs of MM patients. When human MM cell lines U266 were adhered to BMSCs of 9 untreated and relapsed MM patients,and added rhIL-6 to it, there was significant increase of SDF-1α, compared with BMSCs in subjects and MM patients. The expression level of SDF-lα was correlated with the level of CD44v6 (r =0.51, P =0.03). Conclusion The increase of SDF-1α (may be produced by myeloma cells and BMSCs) and CD44v6 (may be produced by myeloma cells) activity is associated with the progress or pathogenesis of MM, and may be involved with tumor invasion. The completion of these processes in vivo may need participation of myeloma cells, BMSCs, IL-6,SDF-lα and CD44v6.

OBJECTIVETo explore the effect of curcumin on TGF-β2 regulated peroxisome proliferater activated receptor y (PPAR-γ)/platelet derived growth factor β (PDGF-β) signaling pathway in lung fibroblasts of mice.

METHODSC57BL/6 mouse lung fibroblasts were in vitro cultured with TGF-β2, curcumin, or TGF-β2 plus curcumin. The cell proliferation was detected by cell growth counting in the blank control group, low, middle, and high dose curcumin groups (5, 25, 50 μmol/L), the TGF-β2 (10 ng/mL) group, TGF-β2 (10 ng/mL) plus curcumin (5, 25, 50 μmol/L) groups. mRNA expressions of PPAR-γ, platelet-derived growth factor receptor β (PDGFR-β), fibroblast growth factor R1 (FGFR1) were detected using reverse transcription PCR. Protein levels of PPAR-γ and collagen-1 were detected using Western blot and ELISA in the blank control group, the TGF-β2 group, the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group.

RESULTSCompared with the blank control group, curcumin 50 μmol/L showed the most significant inhibition on cell proliferation at 48 h and 72 h. Compared with the TGF-β2 group, TGF-β2 (10 ng/mL) plus curcumin 50 mol/L also showed the most significant inhibition on cell proliferation at 48 h and 72 h. Compared with the blank control group, mRNA expressions of PPAR-γ and PDGF-β, as well as protein expression of PPAR-γ increased, the collagen-1 expression also increased in the TGF-β2 group (P < 0.05). Compared with the TGF-β2 group, mRNA expressions of PPAR-γ obviously increased in the TGF-β2 (10 ng/mL) plus curcumin 25 μmol/L group and the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group, higher than that in the TGF-β2 (10 ng/mL) plus curcumin 5 [μmol/L group (P < 0.05). mRNA expressions of PPAR-γ was higher in the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group than in the TGF-β2 (10 ng/mL) plus curcumin 25 μmol/L group (P < 0.05). mRNA expressions of PDGF-β was lower in TGF-β2 (10 ng/mL) plus curcumin groups than in the TGF-β2 group (P < 0.05). Besides, PDGF-β mRNA expressions were lower in the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group than in the TGF-β2 (10 ng/mL) plus curcumin 5 μmol/L group and the TGF-β2 (10 ng/mL) plus curcumin 25 μmol/L group (P < 0.05). There was no statistical difference in FGFR1 mRNA expressions between the TGF-β2 group and 3 TGF-β2 plus curcumin groups (P > 0.05). Compared with the TGF-β2 group, PPAR-γ protein expressions increased and collagen-1 protein expressions decreased in the TGF-β2 (10 ng/mL) plus curcumin 50 μLmol/L group (P < 0.05, P < 0.01).

CONCLUSIONSCurcumin not only could inhibit TGF-β2 induced proliferation of lung fibroblasts, but also could inhibit the synthesis of collagens. These might be associated with up-regulating PPAR-γ expressions and down-regulating PDGF-β expressions. Therefore, curcumin might inhibit the occurrence and developing of lung fibrosis through blocking PPAR-γ/PDGF-β signaling pathway.

BackgroundIdiopathic epiretinal membranes(ERMs) is a common eye disease condition that leads to progressive decline of visual acuity. Studying the risk factors relating to this disease will shed light on its pathogenesis and allow opthalmologists to screen the affected individuals among the high-risk population and prepare for prevention and management strategies. ObjectiveThis survey was to investigate the risk factors of idiopathic ERMs in the population undergoing routine health check-ups. MethodsThe clinical data of idiopathic ERMs was obtained from the population of routine health check-ups in Peking Union Medical College Hospital from November 2009 to October 2010. The examination outcomes were compared between the individuals with and without idiopathic ERMs. The demographic and clinical factors associated with idiopathic ERMs were analyzed and assessed using univariate and multivariate logistic regression analyses. Result A total of 27 400 people were included in the survey and idiopathic ERMs were diagnosed in 76 cases. No obvious eye complaint was obtained from the idiopathic ERMs. The number of people affected with idiopathic ERMs was 12 ( 12/11 659 ) in the below 40 years group, 21 (21/4595) in the 51-60 years group and 32 (32/2544) in the over 60 years group. Hypertension, diabetes, diedyslipidemia, renal function insufficiency ,and cataract were found in 42％ ,5％ ,66％ ,6％ and 8％ of the patients, respectively. The univariate logistic regression analyses revealed that significant correlations were found between age,hypertension,hyperlipidemia and history of cataract( P＜0. 01 ). Multivariate regression models showed that the risk of idiopathic ERMs increased in age of 51-60( OR=2. 5,95％ CI:1. 2-5.4,P=0.02) and over 60 years( OR =7.3,95％ CI:3.4-15.6 ,P＜0.01 ) and patients suffering from hyperlipidemia ( OR--2. 1,95％ CI:1. 3-3.5, P＜0. 01 ). ConclusionsOver the age of 50 years and hyperlipidemia are primary risk factors of idiopathic ERM.
