Objective To explore the role of TGF-βand TGIF in the pathogenesis of endometriosis. Methods The expression of TGF-β and TGIF was detected by immunohistochemistry method in the ectopic and eutopic endometrium of 30 cases with endometriosis (ec-topic endometrium group and eutopic endometrium group) and in the normal endometrium of 40 cases without endometriosis (control group). Result The expression of TGF -β in ectopic endometrium group was significantly higher than that in eutopic endometrium group and control group (P < 0.05). There was no significant difference in the expression of TGF- βbetween eutopic endometrium group and control group(P > 0.05). The expression of TGIF in ectopic endometrium group was significantly lower than that in eutopic endometrium group and control group( P <0.05). There was no significant difference in the expression of TGIF between eutopic endometrium group and control group(P > 0.05). There were negative correlation between the expressions of TGF - β and TGIF in ectopic endometrium group and eutopic endome-trium group(rs= - 0.769, - 0.549, P < 0.05). Conclusion The abnormal expression of TGF-β and TGIF in ectopic endometrium of pa-tients with endometriosis may be associated with the genesis and progression of endometriosis. 相似文献

Objective To investigate the curative effect of different time of irrigating after endolacrimal recanalisation surgery by Nd:YAG laser combining eye ointment stuffing. Methods Seventy-five cases (75 eyes) of lacrimal duct obstruction, which received endo-lacrimal recanalisation surgery by Nd:YAG laser combining eye ointment stuffing were divided into three groups by random digits table with 25 cases in each group. Group A received irrigating: the first day postoperative, consecutive 3 days,followed by once a week till a month. Group B received irrigating:the third day postoperative, consecutive 3 days,followed by once a week till a month. Group C received irrigating:the sixth day postoperative, consecutive 3 days, followed by once a week till a month. Followed-up survey for 12 months at the ophthalmologic outpatient clinic,the curative effect in each group was compared. Results In 6 months after surgery, the comparison of the curative effect was no statistical difference between group B and group C (P> 0.05), while the curative effects in group B and group C was superior to that in group A (P < 0.05). In 12 months after surgery, the curative effect in group C was better than that in group A and B, the difference were statistically significant (P<0.05). But there was no statistical significance compared with group A and group B (P>0.05). Conclusions Properly delayed irrigating may improve the curative effect after endo-lacrimal recanalisation surgery by Nd:YAG laser combining eye ointment stuffing, while easier irrigating can increase the incidence of re-blockage of lacrimal duct and reduce the efficacy. 相似文献

Objective To investigate the effects of schisandrin B (Sch-B) on expression of transforming growth factor-β1 (TGF-β1) and signal transduction molecule mRNA in rat lungs exposed to SiO2,and explore the intervention mechanism of Sch-B on pulmonary fibrosis induced by SiO2. Methods Ninety six Wistar rats were randomly divided into control (normal saline) group, SiO2 group and SiO2 plus Sch-B group.The rats were exposed to SiO2 by direct tracheal instillation to establish the silicotic animal models. SiO2 group and SiO2 plus Sch-B group were treated with 1ml SiO2 (50 mg/ml) for each rat From the first day after model establishment, SiO2 plus Sch-B group were orally given Sch-B (80 mg/kg) a day, control group and silica group were orally given olive oil. On the 3rd, 7th,14th and 28th days after treatment, 8 rats in each group were sacrificed and samples were collected. The histo-pathological examination of lung was performed by HE staining. The expression levels of TGF-β1 、TGFβR Ⅱ and Smad4 mRNA in the lung tissues were detected by RT-PCR. Results The results of histo-pathological examination showed that in SiO2 group, lung tissues were injured obviously; the alveolar inflammation with alveolus interval edema and inflammation cell infiltration appeared on the 3rd and 7th days; the alveolus interval became thicker, became thicker, fibroblast and collagen matiix increased markedly on 14th day; the alveolar structure was damaged, alveolar wall thickened obviously,collagen aggradation and pulmonary fibrosis displayed on 28th day. The alveolar inflammation and pulmonary fibrosis in SiO2 plus Sch-B group were significantly less than those in SiO2 group. The expressions levels of TGF-β1、TGFβR Ⅱ and Smad4 mRNA (TGF-β1: 1.03±0.31 、1.33±0.39、1.08±0.26、0.82±0.16,TGF-βR Ⅱ:0.65 ±0.11、0.80 ±0.16、0.83 ±0.24、0.62 ±0.15, Smad4: 0.87 ±0. 15、0.68 ±0.11、0.78 ±0.19、0.30 ±0.08) in SiO2group were significantly higher than those in the control group (TGF-β1:0.59±0.22、0.55 ±0.25、0.56±0.20、0.55 ±0.12,TGR-βR Ⅱ:0.28 ±0.13、0.31 ±0. 15、0.34 ±0.15、0.27 ±0.09,Smad4:0.23 ±0.11、0.40 ±0. 12、0.39 ±0.12、0.18±0.06)(P<0.01 or P<0.05), but the expression level of TGF-β1 mRNA was the highest on the 7th day. The expression levels of TGF-β1 and Smad4 mRNA (TGF-β1: 0.68 ±0.28、0.88 ±0.25、0.75 ±0.11、0.61 ±0. 14,Smad4:0.25 ±0.12、0.45 ±0.09、0.44 ±0.07、0.21 ±0.04) in SiO2 plus Sch-B group were significantly lower than those in SiO2 group (P<0.01 or P<0.05),but there were no significant differences of the TGFβR Ⅱ mRNA expression levels between SiO2 group and SiO2 plus Sch-B group. Conclusion Sch-B can reduce the pulmonary fibrosis induced by SiO2 through inhibition of the mRNA express of TGF-β1 and Smad4 in the lung tissue, modulating the TGF-β1/Smad4 signal transduction pathway and inhibiting the target gene activation. 相似文献

Objective To investigate the relationship among peroxisome proliferators - activated receptor gamma (PPAR-γ), pul-monary arterial systolic pressure(PASP) ,and insulin resistance in Chronic Obstructive Pulmonary Disease (COPD) patients. Methods A-mong 63 COPD patients, 30 patients with level of PASP above 40mmHg were enrolled in PAH group and other 33 patients were enrolled in COPD group. Twenty healthy medical examination subjects were enrolled in control group. The expression of PPAR-γ, mRNA was detected by real time fluorescent quantitative RT- PCR. Radioimmunoassay was used to measure the level of fasting plasma insulin (FIN). Fasting plas-ma glucose (FPG) was detected by glucose oxidase method. Results The expression of PPAR-γ mRNA was significantly decreased in PAH and COPD group, while FPG, FIN and IRI increased significantly. PAH group had more increased PASP, decreased expression of PPAR-γ and higher IRI than COPD group. Expression of PPAR-γ was negatively related to PASP and IRI. Conclusions The significantly down reg-ulated expression of PPAR-γ maybe explain the higher FPG and PASP. 相似文献

Objective To investigate the effects of dexamethasone on expression of matrix metalloproteinase-9 (MMP-9) in rats with acute lung injury induced by phosgene. Methods The rats were randomly divided into 3 groups: normal control group that consists of the rats with air exposure, phosgene group that consists of the rats with phosgene exposure and dexamethasone group that consists of the rats with phosgene exposure after 2.5 mg/kg dexamethasone being injected. Wet and dry ratio of the lung (W/D) was calculated, and leukocyte count and total protein content of bronchoalveolar lavage fluid (BALF) were recorded at 2 h after exposure. The concentrations of MMP-9 in the serum and BALF were measured by enzyme-linked immunosorbent assay. The pathologic changes of lung tissues were observed under light microscopy. The immunohistochemistry and the RT-PCR were used to detect the contents of MMP-9 in the lung tissue. Results Compared with phosgene group, the lung W/D, protein content and WBC count in of BALF dexamethasone group was significantly decreased (P<0.01). MMP-9 levels of the serum and BALF in dexamethasone group were (4.799±0.043) μg/L and (15.052±0.029) μg/L, respectively, which were significantly lower than those [(9.439±0.100) and (20.640±0.446) μg/L] in phosgene group (P<0.01). Compared with phosgene group (2.789±0.282), the expression level(1.183±0.260) of lung M MP-9 mRNA in dexamethasone group was significantly lower than that in phosgene group (P<0.01).Histological experimental results showed the marked hyperemia and thickening of alveolar wallsand stroma cells infiltrating and more visible alveolar structure damage of alveolar walls in phosgene group while the alveolar structure and the alveolar walls were clear and slightly thickened with inflammatory cells in dexamethasone group. Immunohistochemical results showed that MMP-9 protein expression levels of lung and brochus tissues in normal control group and dexamethasone group were weakly positive, which in phosgene group were strongly positive. Conclusion Dexamethasone has a beneficial effects on acute lung injury induced by phosgene in rats due to the inhibiting MMP-9. 相似文献

Objective To study the expression of adiponectin and α-smooth muscle actin (α-SMA) in liver from the patients of chronic hepatitis B(CHB) overlapped non-alcoholic fatty liver disease( NAFLD), and to explore the mechanism of CHB patients with NAFLD. Methods 94 patients of CHB overlapped NAFLD (case group)underwent liver biopsy, 119 cases of patients with CHB alone (control group) as control, the fasting venous blood sample was taken for liver biochemical and virological indicators. Liver biopsy specimens were immunohistochemically stained for histology, adiponectin and α-SMA, and integral absorbance. Results The serum ALT, total cholesterol, triglyceride, low density lipoprotein cholesterol and fasting glucose levels in case group were significantly higher than that in control group (Z = 3.425,4.488,4.858、2.265, P < 0.05) .There was no significant difference in HBV DNA viral load and HBeAg between the two groups( Z = 0.825, χ2 = 0.323, P > 0.05). In case group, adiponectin expression was no significant correlation with steatosis, inflammation and fibrosis(r = 0.032, -0.107, -0.133, P>0.05); however, in control group adiponectin was negatively related to inflammation and fibrosis(r= -0.223, -0.259,P<0.05). In case group,α-SMA expression was significant correlation with inflammation and fibrosis( r = 0.323,0.355, P < 0.05). In control group, its expression was no correlation with inflammation and fibrosis( r = 0.172,0.155, P > 0.05). Conclusions The occurrence of NAFLD is mainly related to metabolic factors and no relation with viral factors. Adiponectin is not directly related to liver injury of patients of CHB overlapped NAFLD. α-SMA may be important indicator of liver injury,and NAFLD may promote the progress of liver injury in patients with CHB. 相似文献

Objective To investigate the effect of diuretic (furosemide) therapy on kidney injury induced by melamine and cyanuric acid in rats. Methods 36 male Spragne Dawley rats were random disided into 3 groups. Group A was treated with 2mL of water daily, group B was treated with melamine and cyanuric acid ( each 100 mg/kg) daily for 4 days and then 2ml of water daily, group C was treated with the same as group B at the first 4 days and then treatment with furosemide (20mg/kg) daily. Samples of blood and 24h urine were collected to detective biochemical indexes, and kidney sections were performed on days 4 and 11 ( each end point, n = 6). The kidneys were observed with histopathology and renal crystal deposition scores were determined. Results On the 4th day, group B and group C were resulted in acute kidney injury such as oliguria [ ( 3. 39 ± 1.02 ) ml, ( 3. 20 ± 0. 86 ) ml ] and high serum creatinine [ ( 153.54 ±27. 08)μmol/L, (160. 11 ± 19. 55)μmol/L] and renal melamine cyanurate crystal were found in the renal tissues. On the 11th day, the renal crystal deposition score in the rats was reduced by 9. 52% ( P >0. 05). Compared with those of the 4th day in group B, it reduced by 63.63%( P <0.05) in group C. Urine volume were increased significantly compared with those of the 4th day( P < 0. 05 ) in group C [ from (3.20±0. 86)ml to (25.96 ±5.97)ml] and group B [ from(3. 39 ± 1.02)ml to (8. 57 ± 1.66)ml] , and Urine volume in group C was increased significantly more than that in group B ( P < 0. 05 ). The serum creatinine was obviously reduced as compared with those of the 4th day in group B and C( P <0.05), from[ (153. 54±27.08) μmol/L] to [ ( 106. 10 ±5.53) μmol/L] in group B and from [ ( 160. 11 ± 19. 55) μmol/L] to [ (67. 17 ± 12. 80 ) μmol/L] in group C, but the serum creatinine in group B was still higher than that in group A and C ( P < 0. 05). Conclusions Furosemide can attenuate the damage of acute kidney injury induced by melamine and cyanuric acid. 相似文献

Objective: To explore the effect of cryopreservation on the mitochondrial DNA (mtDNA) deletions and energy metabolism of human oocyte, so as to investigate the effect of cryopreservation on oocytes preservation. Methods: The dumped oocytes with 0PN, 2PN and 3PN during routine IVF were collected for this cryopreservation study. Those oocytes were randomly divided into two groups, one for vitrification cryopreservation (Group A) and the other as control (Group B, without cryopreservation). The nested polymerase chain reaction (PCR) was used to detect the mtDNA deletions of oocyte mtDNA before and after cryopreservation. Real-time quantitative PCR was adopted to determine the copy number of oocyte mtDNA. ATP contents were detected using luciferin-luciferase assays. Results: There were not significant differences in the mutation frequency of oocyte mtDNA deletions and the copy number of mtDNA between two groups (P>0.05). However, The ATP content in the group A was significantly lower than that in the group B. Conclusions: The effect of cryopreservation on the oocyte mtDNA deletions and the copy number of mtDNA was limited, suggesting that cryopreservation can be properly used to preserve oocyte.
