ABSTRACT
Objective:To observe ulcer characteristics of Crohn's disease under double balloon enteroscopy,and to evaluate the correlation between endoscopic severity and clinical manifestations.Methods:A prospective,observational study from July 2015 to December 2016 in the Third Xiangya Hospital,Central South University,we selected 45 patients with positive double-balloon enteroscopy (DBE) and confirmed Crohn's disease.Two digestive internal physician observed the ulcer characteristics of Crohn's disease under double balloon enteroscopy,and gave a simple endoscopic score for CD (SES-CD).We analyzed the correlation between SES-CD and Crohn's disease activity index (CDAI).Results:DBE indicated 24 patient ulcers (53.33％) locating at the end of the ileum,5 (11.11％)locating at ileocolon,16 (35.56％) locating at upper gatrointestinal tract and they did not affect the end of the ileum.Among them,8 cases (17.78％) affected only jejunum.Thirty-two patients with longitudinal ulcers in Crohn's disease,accounting for 71.11％.There was no correlation between SES-CD score and CDAI score (r=0.237,P=0.136).Conclusion:The ulcerative appearance in Crohn's disease were diverse under double balloon enteroscopy.Crohn's disease could only affect the upper gastrointestinal tract or jejunum.The unwounded ileum and ileocecal valve couldn't be a sign to exclude Crohn's disease.CDAI score couldn't fully assess the prognosis of Crohn's disease.
ABSTRACT
Objective:To analyze the change of bone mineral density (BMD) in postmenopausal women,and to study the relationship between BMD and the estrogen,cytokines,and serum levels of bone metabolism.Methods: 135 postmenopausal women were divided into the OP group (n=54),Osteopenia group (n=43) and normal group (n=38) according to the results of lumbar spine bone mineral density (BMD) scan.To detected the concentration of serum estradiol (E2),bone alkaline phosphatase (BALP) and osteocalcin (BGP),tartrate resistant acid phosphatase-5b (TRAP-5b),interleukin-6 (IL-6),tumor necrosis factor alpha (TNF-α),transforming growth factor beta (TGF-β1) and IL-10 of research objects in the three groups.And to analyze the relationship between BMD and the levels of E2,BALP,BGP,TRAP-5b,IL-6,TNF-α,TGF-β1 and IL-10.Results: In the OP group and the Osteopenia group,BMD and the levels of E2,TGF-β1 and IL-10 were obviously lower than that in the normal group (P0.05).The low serum E2 levels and high serum levels of BALP,BGP,TRAP-5b,IL-6 and TNF-α were the independent factors affecting the reduction of BMD (P<0.05).Conclusion: The E2 level in patients with PMOP decreased obviously,which caused the imbalance of bone remodeling and inflammatory reaction,and which was related to the decrease of BMD.
ABSTRACT
Objective:To explore the effect on sex hormone functional of extracts of Herba Epimedii /Fructus Ligustri Lucidi in osteoporosis rats.Methods:50 cases of 3 months Wistar rats were rando mly divided into normal group ,model group,extract low dose group(extract-L),extract middle dose group(extract-M),extract high dose group(extract-H),10 cases in each group,in addition to the normal group,other 4 groups were bulided OP model by filling and feeding retinoic acid for 15 d,then normal group and model group were filling physiological saline;extract-L,extract-M,extract-H were respectively feeding extracts of Herba Epimedii /Fructus Ligustri Lucidi at 50 mg/kg,100 mg/kg,200 mg/kg,both for 3 weeks.Measured the bone mineral density (BMD),observed the femoral pathology change of left femur with hematoxylin and eosin ( HE ) staining, measured trabecular bone tissue morphology related parameters ,analyzed the hormone receptor protein expression with immunohistochemistry .Results:The BMD of the whole femur ,femur head,and femur neck in normal group were all significantly higher than that of model group ,the BMD of the whole femur ,femur head, and femur neck in extract-M and extract-H group were all significantly higher than that of model group ,the BMD of the whole femur in extract-L group was significantly higher than that of model group ,the differences were statistically significant (P<0.05 or P<0.01).The bone trabecular number had significantly increased ,integrity,continuity improved significantly ,bone histomorphometry such as Tb.Ar, Tb.Th,and Tb.N in model group were decreased ,and Tb.Sp was increased,extract-M and extract-H group had remarkable effect on each index ,while extract-L group only had a remarkable effect on Tb .Ar and Tb.Th ( P<0.05 or P<0.01 ) , compared with model group.The expression of AR , ER in normal groups were significantly higher than that of model group , the expression of AR , ER in extract-H group was significantly higher than that of model group , the differences were statistically significant ( P<0.05 or P<0.01 ) . Conclusion:This study demonstrated that the combination with TFE and TIFL had potential protective effects on osteoporosis rats induced by retinoic acid .The combination with TFE and TIFL is able to increase BMD ,reverse pathological changes of bone tissue ,co-ordinate hormones of the hypothalamic-pituitary-gonadal axis ,and upregulate the expression of sex hormone receptors .
