AIM:To investigate the expression of angiotensin-converting enzyme 2 (ACE2) in nephritic epithelium of primates. METHODS:The expression of ACE2 in Vero E6 cells was detected by the techniques of RT-PCR and immunocytochemistry (ICC) techniques. The distribution of ACE2 protein in kidney tissues of two Rhesus monkeys and two normal human cases was observed by immunohistochemistry (IHC) techniques. RESULTS:Vero E6 cells were found to express both ACE2 mRNA and protein. ACE2 protein was mainly located in epithelium of proximal tubules of Rhesus monkey and human kidney. CONCLUSION:The expression of ACE2 in epithelium of primate kidney may provide the condition for SARS-CoV entry,which may be one of the reasons for inducing renal damage in SARS patients.

Objective To explore the establishment of WeChat teaching platform and evaluate the effect of micro-lectures in obstetrics and gynecology teaching. Methods A total of 116 trainees (experi-mental group) of 2014 grade and 113 trainees of 2013 grade (control group) were enrolled in the study. The Students' ability of self-learning and collaborative innovation were measured with LASSI and CUCEI scales, and their academic performance was evaluated with using t test. Results The comparison of the four know-ledge modules showed that the differences in the results of the two knowledge modules, the ectopic pregnancy (P=0.00) and uterine fibroids (P=0.01) between the experimental group and the control group were signifi-cant. Besides, the comparison of students' literacy suggested that the differences in time management (P=0.01), selection of main points (P=0.04), innovation (P=0.00) and collaboration capability (P=0.03) between the experimental group and the control group were obviously significant. Conclusions Micro-lectures-assisted teaching can effectively improve students' academic performance, which has important practical value for improving students' self-learning ability, innovation and collaboration.

Ongoing study on the chemical constituents of the roots of Macleaya microcarpa led to the isolation of eight compounds of derivatives of triterpenes and organic acids in addition to some previously identified benzophenanthridines. The eight compounds were identified by spectroscopic methods as well as comparison with literature values as 1-oxo-2, 22 (30)-hopandien-29-oic acid (1), 3-oxo-12-oleanen-30-oic acid (2), 3α-hydroxy-12-oleanen-30-oic acid (3), 3β-hydroxy-12-oleanen-30-oic acid (4), ferulic acid (5), ferulic acid 4-O-β-D-glucoside (6), 3-O-feruloylquinic acid (7), and methyl 3-O-feruloylquinate (8). Of which, 1 is a new triterpenoid of hopanes and 2-8 are isolated from M microcarpa for the first time. In order to discover natural active compounds as potential agents of anti-ulcerative colitis (UC), an in vitro drug high-throughput screening model targeted x-box-binding protein 1 (xbp1) was employed to evaluate the activity of the major chemical constituents of M microcarpa. The result confirmed that two dihydrobenzophenanthridines, dihydrosanguinarine (9) and dihydrochelerythrine (10), showed a certain activity on activating the transcription of xbpl, a transcription factor (TF) associated with the occurrence, development, and potential treatment of UC, with their relative activating ratios being 1.76 and 1.77 times, respectively, as compared with control group.

AIMTo explore the resistant arterial effect of superoxide anion and its possible mechanisms.

METHODSThe third branch of the superior mesenteric artery in male Sprague-Dawley (200-300 g) rats was rapidly excised. Periadventitial fats and connective tissues were removed and the artery was dissected into about 2 mm rings. Each ring was dispensed between two stainless steel wires (diameter 0.0394 mm) in a 5 ml organ bath (DMT 610 M, Danish Myo Technology, Denmark). Isometric force recording studies in vitro of rat mesenteric arterial rings were recorded by Powerlab Syetem. Exposure of arteries to superoxide was accomplished through the auto-oxidation of pyrogallol added to the artery baths. Then endothelium-dependent or independent relaxation was investigated, respectively.

RESULTSExposure to pyrogallol (10, 100, 300, and 1 000 micromol/L) which could produce superoxide anion for 15 min resulted in a dose-dependent manner in a decrease of acetylcholine(ACh)-induced relaxation in rat mesenteric artery. Especially, the two predominant components of acetylcholine(ACh)-induced endothelium-dependent relaxation, EDHF component and NO component were both inhibited by superoxide anion from pyrogallol. However, exposure to superoxide anion from pyrogallol had no effect on the endothelium-independent relaxations to pinacidil or sodium nitroprusside (SNP) in rat mesenteric artery.

CONCLUSIONThese results indicate that superoxide anion can inhibit the endothelium-dependent relaxation in rat mesenteric artery, but has no effect on the endothelium-independent relaxation, in which the inhibited effect of EDHF and NO from endothelium is involved.

OBJECTIVETo establish a new culture method to induce the differentiation of embryonic pancreatic cells into mature endocrine cells.

METHODSMouse embryos at day 12.5 were used and embryonic pancreata were isolated. The isolated embryonic pancreata were cultured on the filter for 7 days, which floated in the dish containing medium. During culture, the expression of pancreas duodenum homeobox-1 (PDX-1), a pancreatic stem cell marker, was examined at day 1. The expression of neurogenin 3 (Ngn3), a pancreatic progenitor cell marker, was examined at day 3. The expressions of endocrine and exocrine markers, insulin, glucagon, and carboxypeptidase (CPA) were examined at day 7 by immunohistochemistry. The kinetics of pancreatic marker expression during culture was assayed by real-time PCR.

RESULTSMany pancreatic stem cells still existed in embryonic pancreata cultured for 1 day; meanwhile, these pancreatic stem cells proliferated in high rate. A large amount of pancreatic progenitor cells were found in embryonic pancreata cultured for 3 days.Pancreatic stem/progenitor cells differentiated into mature endocrine and exocrine cells in embryonic pancreata after having been cultured for 7 days. Furthermore, the expression pattern of pancreatic marker is consistent with that in vivo.

CONCLUSIONWe successfully established a new culture method, with which embryonic pancreatic cells can efficiently differentiate into mature endocrine cell.
