Objective:To study the effect of corticotrophin-releasing hormone(CRH) on estrogen production in human trophoblasts and its mechanisms. Methods: Cytotrophoblasts were isolated from term human placentas and cultured for 72 h. The cultured cells were then treated with various concentrations of CRH and CRH receptor antagonist,?-Helical CRH9-41 for 24 h; estradiol was measured by radioimmunoassay in the culture media. Expression of aromatase(P450arom),the key enzyme for estrogen synthesis,was analyzed by Northern blot. Results: CRH significantly stimulated estradiol production and the expression of P450arom mRNA in placental cells. It was found that ?-Helical CRH9-41 blocked the effect of CRH and inhibited estradiol production and P450arom mRNA expression(P

Purpose To study the exposure extent of internal carotid artery siphon (ICAS) before and after removing anterior clinoid process (ACP) using multislice spiral CT (MSCT) simulation, and to improve the tumor resection rate and ensure the operation effect. Materials and Methods MSCT three-dimensional images reconstruction simulating supraorbital keyhole approach of 100 patients (200 sides) were observed, the distance between the crotch of anterior cerebral artery and middle cerebral artery and ICAS before and after removing ACP (exposure extent) was measured. Results In 100 patients (200 sides ACP), the exposure extent before and after removing ACP were (14.3±3.9) mm and (30.5±4.2) mm, respectively on the left side with statistical difference (t=45.278, P<0.001), and were (15.9±3.8) mm and (31.8±3.9) mm, respectively on the right side with statistical difference (t=40.513, P<0.001). The exposure extent increased (16.3±3.6) mm and (15.8±3.9) mm, respectively on the left and right side with no statistical difference (t=0.251, P>0.05). Conclusion MSCT simulating supraorbital keyhole approach in removing ACP can effectively increase the exposure length of ICA, and enlarge the exposure extent of sella region, thus provide reliable imaging information for removing tumor and selecting surgical project in this region.

Objective To observe the anatomy status of the anterior clinoid process (ACP)and the anterior clinoid segment of in-ternal carotid artery (ICA)respectively by multisliced computed tomography (MSCT),and to provide useful imaging information for ACP removal surgery.Methods A total of 100 patients (200 sides)had volume rendering reconstruction of skull.Cranium was removed along cranio-orbital bone in simulation.Then the anatomical structures of the ACP and its surrounding were observed in cephalad direction.The total length,medium length,basic width,medium width of the ACP and the sagittal view curve length of anterior clinoid segment of the ICA from both sides were measured.Results Total length of left ACP was (9.82±2.48)mm,basal width was (9.47±1.88)mm,medium length was (5.03±1.55)mm,medium width was (6.1 9 ±1.75)mm;for right side total length was (10.41±2.1 6)mm,basal width was (9.66 ±2.21)mm,medium length was (5.86 ±2.48)mm,medium width was (6.66±1.5 1)mm.Left anterior clinoid segment of ICA curve length was (6.74±2.25)mm;right was (8.54±3.00)mm.Paired sample t test showed no significant difference in total length,basal width and medium width of ACP in both sides (P >0.05);while the difference in medium length and curve length of the anterior clinoid segment of ICA were statistically significant respectively (P <0.05).Conclusion MSCT can clearly display the vivisection and variation status of the ACP and the anterior clinoid segment of the ICA and can provide useful imaging information for removal of ACP in operation.

OBJECTIVE: To analyze the effects of Astragalous Injection on oxidative stress and micro-inflammatory status in patients undergoing maintenance hemodialysis (MHD). METHODS: Sixty MHD patients were included and randomized into treatment group and control group, with another 10 healthy volunteers as normal control. The patients in the treatment group were treated with Astragalous Injection and the patients in the control group were treated with normal saline for 12 weeks. A spectrophotometric method was used for the measurement of plasma concentrations of oxidative parameters including advanced glycation end products (AGEs), advanced oxidation protein product (AOPP), malondialdehyde (MDA) and vitamin E (Vit E). The content of C-reactive protein (CRP) was evaluated by enzyme-linked immunosorbent assay. RESULTS: Compared with the normal control group, the plasma levels of AGEs, AOPP, MDA and CRP were significantly increased, while plasma level of Vit E was significantly decreased in MHD patients ( P<0.01). After Astragalous Injection treatment, the plasma levels of AGEs, AOPP, MDA and CRP were decreased as compared with the control group ( P<0.01), while there was no significant difference in plasma Vit E level between the treatment group and control group. CONCLUSION: There exist oxidative stress and micro-inflammation in MHD patients. Astragalous Injection can ameliorate the accumulation of oxidative products and micro-inflammatory status, but it has no significant effect on plasma Vit E level.

As a common emotional and psychogenic disorder, anxiety disorder seriously threats the human physical and mental health. Ventral tegmental area (VTA) is the canter of the mesocortical limbic circuit, with extensive bidirectional connections to forebrain areas, and plays important role in regulating reward, motivation, cognition, and disgust. Besides, VTA is involved in anxiety regulation by forming functional connections with multiple brain regions and connecting external stimulus information and feedback output behaviours. This article briefly summarizes the different cell subsets of VTA and its involvement in anxiety-related neural circuits.

Objective:
To observe the expression level of microRNA-181 (miR-181) and importin-α3 in oxidized low density lipoprotein (ox-LDL) induced vascular endothelial cell injury models, and explore the effect and mechanism of miR-181 on endothelial cell injury.
Methods:
Human vein endothelial cell line CRL-1730 were cultured and vascular endothelial cell injury model was established by intervention with ox-LDL. The cells were divided into control group (intervened by double distilled water), low-dose group (intervened by 10 μg/ml ox-LDL) and high-dose group (intervened by 20 μg/ml ox-LDL). In addition, cells of low-dose group were divided into miR-181 mimic group (miR-181 mimic was transfected) and mimic control group (miR-181 mimic control was transfected). Cell viabilities, mRNA and protein expression level of interleukin-6 (IL-6), miR-181, importin-α3, and nuclear transcription factor-κB (NF-κB) were measured by methyl thiazolyl tetrazolium (MTT), real-time PCR and Western blot, respectively.
Results:
(1) The cell viabilities in low-dose group and high-dose group were lower than control group (0.207±0.012 and 0.204±0.007 vs. 0.323±0.018, all
