Diagnostic value of hysteroscopy in determining the etiology of postmenopausal intrauterine fluid collection / 中华老年医学杂志

Objective To investigate the clinical value of hysteroscopy in helping identify the etiology of intrauterine fluid collection in postmenopausal women.Methods One hundred and thirtyfour postmenopausal women with intrauterine fluid collection,detected via transvaginal sonography,were admitted in the department of gynecology and obstetrics at Beijing ChaoYang Hospital from May 2014 to October 2016.All clinical data were retrospectively analyzed.All patients underwent hysteroscopy and biopsy of the endometrium.The results of hysteroscopy were analyzed against biopsy results.Results Hysteroscopy revealed that 116 of the 134 cases had uterine fluid(86.6％).Based on hysteroscopy results,44 (37.9 ％) had endometritis,10 (8.6 ％) had atrophic endometritis,5 (4.3 ％) had endometrial carcinoma,and 7(6.0 ％)had endometrial polyps,but the case numbers and rates for these conditions from microscopic examination were39 (33.6％),15 (12.9％),6 (5.2％),and 7 (6.0 ％),respectively.When microscopic examination was used as the gold standard,the sensitivities and specificities of hysteroscopy in the diagnosis of endometritis,atrophic endometritis,endometrial cancer and endometrial polyps were 82.0 ％ and 85.7 ％,66.7 ％ and 97.1％,80.0 ％ and 98.2 ％,and 100.0％ and 97.3％,respectively.The diagnostic coincidence rates were 84.6％,93.2％,94.4％ and 97.4％,respectively.Conclusions Postmenopausal women with intrauterine fluid collection shown on transvaginal sonography should receive hysteroscopy for early detection of endometrial lesions.

Comparative study on toxicity of Euphorbia before and after being prepared by vinegar / 中国中药杂志

<p><b>OBJECTIVE</b>To study and compare the changes of toxicity of Euphorbia pekinensis, E. kansui and E. ebracteolata before and after being prepared by vinegar.</p><p><b>METHOD</b>Small intestinal accentuation of mice and peritoneal macrophage NO release experiments were assessed to investigate the changes of toxicity of the three Chinese Medicines of Euphorbia before and after being prepared.</p><p><b>RESULT</b>E. pekinensis, E. kansui and E. ebracteolata and vinegar can obviously promot small intestinal accentuation and peritoneal macrophage NO release with the intensity of toxicity in the order of E. kansui > E. pekinensis > E. ebracteolata. After being prepared with vinegar, the toxicity of the three medicines decreased obviously compared to crude one.</p><p><b>CONCLUSION</b>E. pekinensis, E. kansui and E. ebracteolata can induce inflammation and accelerate enterokinesis. After being prepared with vinegar, the irritation on Euphorbia decreased obviously.</p>

Prevention of Eperidural Fibrosis and Adhesion after Laminectomy with Tetramethylpyrazine and Autogenous Periosteum Graft / 中国康复理论与实践

@#ObjectiveTo study the effect of tetramethylpyrazine cooperated with autogenous periosteum graft on fibrous scar formation in the epidural space after laminectomy. Methods48 SD rats were divided randomly into 4 groups. Laminectomy was performed in lumbar 2 segment, and the exposed duras were covered with saline solution (group A), tetramethylpyrazine (group B), autogenous periosteum (group C), and tetramethylpyrazine and autogenous periosteum (group D) respectively. 12 weeks postoperatively, they were evaluated with the gross and histopathological observation, biochemistry examination. ResultsThe assessment of Rydell-Balazs and Nussbaum's Criterion of group B, C, D were obviously better than that of group A (P<0.01), and that of group D was superior to group B and C (P<0.05), no significant difference between group B and C (P>0.05). ConclusionTetramethylpyrazine cooperated with autogenous periosteum graft has a better effect on prevention peridural adhesion after laminectomy.
