In order to observe the effect of ursodeoxycholic acid (UDCA) in the treatment of intrahepatic cholestasis of pregnancy (ICP), 68 patients with ICP were equally divided into treatment group and control group at random. The patients in treatment group were administered with UDCA 300 mg three times every day and those in control group received a combination of 10% glucose, Vitamin C and Inosine. Itching scores, serum ALT and total bile acids (TBA) were measured before, during and after treatment. The results showed that as compared with those before treatment, itching scores, serum ALT and TBA were significantly reduced after treatment (P < 0.05). The occurrences of premature labor, fetal asphyxia and meconium staining in amniotic fluid were significantly lower in treatment group than in control group (P < 0.05). It was suggested that UDCA was an effective drug in the treatment of ICP.

This study examined the association of expression of vascular endothelial growth factor (VEGF), a promoter of angiogenesis, with endothelium dysfunction in preeclampsia. The level of VEGF protein and mRNA in the placenta and peripheral blood samples of 30 preeclampsia patients and 30 normotensive pregnant women was measured by immunohistochemistry, real-time reverse transcriptase-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. VEGF expression in the human umbilical vein endothelial cells (HUVECs) was blocked by small interfering RNAs (siRNAs). The monolayer barrier function of HUVECs was determined by measuring the fluorescence intensity of BSA that crossed the HUVEC monolayers. The cell proliferation and cell-secreted nitric oxide (NO) level were detected by MTT method and nitrate reductase assay, respectively. The results showed that VEGF was expressed in the syncytiotrophoblasts and endothelial cells of vessels and capillaries in the placenta tissue. The serum level of VEGF in the preeclampsia patients was significantly decreased as compared with that in normal pregnant subjects, although VEGF mRNA expression in the placenta tissue of preeclampsia patients remained still high. Moreover, VEGF deficit could lead to endothelium cell dysfunction, and the administration of VEGF could protect endothelium cells from injury. It was concluded that lack of VEGF contributes to endothelium dysfunction, which may lead to the occurrence and development of preeclampsia.

Objective:To study the role of adhesion molecules in the pathogenesis of polymyositis. Methods:The abnormal expression of adhesion molecules on T cells in peripheral blood and muscle fibers from patients with myositis was analyzed by two colour immunofluoresence and RT PCR methods respectively. Results:The expression of adhesion molecules including lymphocyte function associated antigen 1(LFA 1 ),very late antigen 4(VLA 4) on T cells in peripheral blood and intercellular adhesion molecule l(ICAM 1) on muscle fibers from patients with myositis was markedly higher than that in the healthy control group. Conclusion: These findings suggested that adhesion molecules may be responsible for the migration of T cells and destraction of muscle fibers.

ObjectiveTo investigate the effects of vascular endothelial growth factor (VEGF) and dexamethasone on mRNA expressions of surfactant protein B (SP-B) and transforming growth factor-β1 (TGF-β1) of type Ⅱ alveolar epithelial cell (AECⅡ). MethodsAECⅡ were isolated and purified from fetal rat lung tissues,then cultured with different dose of VEGF (25,50 and 100 ng/ml) and dexamethasone (25,50,100 and 200 nmol/ml).The mRNA levels of SP-B and TGF-β1 were detected by real-time quantitative polymerase chain reaction (RT-PCR) and expression of TGF-β1 protein was detected by immunocytochemistry.ANOVAor q-test wasappliedtocompare the difference among groups.ResultsCompared with control group,SP-B mRNA levels in 25 ng/ml VEGF group and 25,50,100 and 200 nmol/ml dexamethasone groups were higher (13.500±3.172,3.547±0.690,5.219±0.782,3.493±0.335,and 3.981 ± 1.133 vs 1.001 ± 0.059,q=-5.286,-4.943,- 7.228,- 9.906 and - 3.525 respectively,P＜0.05) ; TGF-β1 mRNA expression of 25 ng/ml VEGF group,50,100 and 200 nmol/ml dexamethasone group was lower (0.451 ± 0.078,0.579±0.019,0.422 ± 0.020 and 0.769 ± 0.025 vs 1.019±0.226,q=4.110,3.356,4.551 and 1.901 respectively,P＜0.05) ; other groups had no significant differences compared with control group (P＞0.05).Immunocytochemistry showed that the positive rate of TGF-β1 expression in 25 ng/ml VEGF,50,100 and 200 nmol/ml dexamethasone group was 23％,26％,22％ and 29％,respectively,while in the control group,the expression of TGF-β1 was positive in most of the AECⅡ (80％).ConclusionsBoth VEGF and dexamethasone could increase the expression of SP-B at mRNA level at appropriate concentrations.At the same time,the expression of TGF-β1 is inhibited.It is suggested that both VEGF and dexamethasone might increase the mRNA expression of SP-B by inhibiting the expression of TGF-β1.

Objective:The treatment of late pregnancy complicated with utedne leiomyoma was investigated.Methods:193 Cases of Iate pregnancy complicated with uterine leiomyoma from January 2003 to August 2008 were recruited in our hospital.According to the delivery route,size and subtype of fibroid,blood loss,operation hours and postoperative inpatient period were compared.Results:104 cases of pregnancy complicated with uterine leiomyoma were diagnosed before cesarean section(CS).No significant differences on blood losses and operation hours were found between CS group and CS+myomectomy group(P>0.05).The operation heurs of leiomyoma in corpus uteri was significantly shorter than leiomyoma in lower uterine segment and cervix(P=0.007).Leiomyoma bigger than 8 cm needed significantly Ionger operative hours and lose more blood than the smaller leiomyoma.Operation hours,blood loss and postoperative inpatient period were significantly different between submucous leiomyoma and subserosal leiomyoma(P<0.05).Conclusions:Pregnancy complicated with uterine leiomyoma should be diagnosed as early as possible.During cesarean section on when leiomyoma is bigger than 8 cm,locating at lower uterine segment or cervix or submucous,the treatment should be cautious.
