Objective To investigate the influence of intrahepatic cholestasis of pregnancy (ICP) on the pulmonary morphologic changes of fetal rats.Methods Twenty pregnant SD rats at 15 days of gestations were randomly divided into ICP and control group.Rats in the ICP group were subcutaneously injected with 17-α-ethinylestradiol and progesterone for 5 consecutive days to establish the rat ICP model, and those of the control group received subcutaneous injection of sirasimeyu also for 5 days.The levels of serum alanine aminotransferases (ALT), aspartate transamlnase (AST), and total bile salt (TBA) were measured before and after the treatment, respectively.Maternal rats were sacrificed on 21 days of gestations and hysterotomies were performed immediately.Histopathologic changes of mammal rats' livers and fetal lungs were observed under light and electron microscopes.Results (1) The maternal serum levels of ALT, AST, and TBA showed no significant difference between the ICP and control group [ALT: (55 ± 15) vs (49 ±12) U/L; AST:(146±16)vs (145±20) U/L; TBA: (13±4) vs (14 ±4) μmol/L, P>0.05, respectively]before the ICP models were established, but higher levels were shown in the ICP group after [ALT: (94±12) vs (59±17) U/L; AST: (245±26) vs (163±27) U/L; TBA: (44±16) vs (17± 3) μmol/L, P <0.05, respectively].(2) The livers of maternal rats' in the ICP group were gloomy with blurred margins, however those of the control group were normal.Microscopic observed swollen and degenerated hepatocytes with narrowed hepatic sinusoid, dilated bile duct and necrosis of hepatocytes occasionally in the ICP group, while the morphology of hepatocytes and structures of lobuli hepatis in the control group were normal.(3) The fetal pulmonary tissues in the ICP group were dark, and normal in the control group.Histopathologic examination showed matured fetal pulmonary tissues with dilated and congested interstitial lung capillaries, thickened alveolar septum, mild focal inflammatory exudation and focal hemorrhage in alveolus.Furthermore, reduced microvilli, mitochondrion vacuolization, cytoplasm disintegration and increased lamellar body evacuation were observed in type Ⅱ pneumonocytes in ICP group under light and electron microscopes.While fetal pulmonary tissues of the control group did not show any significant lesions.Conclusions Rat model of ICP can be established with the combination of estrogen and progestin.Hyperbileacidemia in ICP rat may lead to pathological changes in fetal pulmonary tissues.

Gallstone disease is highly prevalent in clinic,particularly in women and some specific ethnic groups.The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile:cholesterol,bile salts,and phospholipids.Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcription factors,including nuclear receptors LXR and FXR.Human and murine genetic,pathophysiological evidence is consistent with the relevance of these nuclear receptors in gallstone formation.In addition,there is emerging data that also suggests a role for estrogen receptor ESR1 in abnormal cholesterol metabolism leading to gallstone disease.A better comprehension of the role of nuclear receptor function in gallstone formation may help doctors to design new and more effective therapeutic strategies for this highly prevalent disease condition.

Objective:To investigate the value of magnetic resonance imaging, CT and X ray radiography on preoperative diagnosis of osteoporotic vertebral compression fracture and post-operation follow up of percutaneous kyphoplasty.Methods: A retrospectively analysis was adopted for 41 patients of osteoporotic vertebral compression fracture, who were detected by X ray, MRI examination and CT analyze, respectively. And the values of 3 methods for preoperative diagnosis of osteoporotic vertebral fractures and X-ray in postoperative follow-up were analyzed. Results: For preoperative diagnosis of osteoporotic vertebral compression fractures, the accuracy rate of MRI, X-ray and CT were 100%(41/41), 65.85%(27/41) and 92.85%(13/14), respectively. Both of the accuracy rates of MRI and CT were higher than X-ray, and the differences were statistical significant (x2=16.882,x2=3.837;P<0.05); the difference of accuracy rate between MRI and CT was not significant (x2=2.983,P>0.05). After the third day of post-operative and during last follow up, anterior vertebral height and middle vertebral height were significantly higher than before operation (F=17.094,F=15.526,P<0.05); and the Cobb angle and the VAS score of lumbar back pain were lower than before operation, the difference was statistical significant (F=41.085,F=107.338;P<0.05).Conclusion: For preoperative diagnosis of osteoporotic vertebral compression fractures, the accuracy rate of MRI is the highest and X-ray is lowest. X-ray can be used to evaluate surgery effect during postoperative follow-up.
