OBJECTIVETo study the effect of Compound Ezhu Powder (CEP) on serum levels of CA125 and CA19-9, and the expression of cyclin D protein in endometriosis patients, thus providing theoretical evidence for clinical application of CEP.

METHODSTotally 69 all endometriosis patients underwent surgical treatment at Department of Gynecology and Obstetrics, Tianjin Nankai Hospital from January 2011 to January 2013 were randomly assigned to group A (35 cases) and group B (34 cases). Meanwhile, 30 patients with uterine fibroids who prepared for surgical treatment during the same period were recruited as the control group. Patients in group A took EZP 3 months before surgery. No treatment was given to patients in group B and the control group. The serum CA125 level and the expression of cyclin D in the ectopic endometrium and the eutopic endometrium were detected in the 3 groups before surgery.

RESULTSThe expression of cyclin D was higher in group A and group B than in the control group (P < 0.05). The serum levels of CA125 and CA19-9 were significantly lower in group A than in group B (P < 0.05). The expression of cyclin D in the ectopic endometrium was lower in group A than in group B, but with no statistical difference (P > 0.05). The expression of cyclin D in the eutopic endometrium was significantly lower in group A than in group B with statistical difference (P < 0.05). Meanwhile, the serum CA125 level was positively correlated with the serum CA19-9 level (r = 0.45, P < 0.05).

CONCLUSIONSThe expression of cyclin D obviously increased in endometriosis patients, which was associated with the occurrence of endometriosis. CEP could lower serum levels of CA125 and CA19-9, and down-regulate the expression level of cyclin D, indicating its roles in inhibiting the cell cycle.

Objective To investigate the imaging diagnosis and surgical treatment of intestinal malrotation in adult patients. Methods The clinical data of 11 adult patients with intestinal malrotation who had been admitted to General Hospital of PLA from January 2003 to December 2007 were retrospectively analyzed. Multiple imaging modalities, including barium enema, gastrointestinal radiography, B sonography, computed tomography (CT) scan and mesenteric angiography were applied for diagnosis. All patients received Ladd procedure. Results Two patients were diagnosed by gastrointestinal radiography +B sonography, 4 by gastrointestinal radiography +CT scan, 1 by angiography, 1 by B sonography + CT scan, 1 by iodine radiography + CT scan and 2 by intraopera-tive examination. After the operation, 2 had renal insufficiency, 1 had intestinal fistula and 1 had short bowel syndrome and died at the third month after operation. Conclusion Combined application of multiple imaging modalities can improve the diagnostic rate, and Ladd procedure is effective and safe for adult patients with intes-tinal malrotation.

Objective To explore the proliferation of microglia in the frontal cortex,hippocampus and amygdala of the post-stroke depression (PSD) in rats.To understand the role of microglia in the pathogenesis of PSD.Methods The adult female SD rats were divided into four groups(n=5 per group):normal control group,depression group,stroke group and PSD group.In the depression group,the depression model rat were established by chronic unpredictable mild stress (CUMS) combined with separately breeding.In the stroke group,focal cerebral ischemic rat models were established with thread embolization method.In the PSD group,focal cerebral ischemic models rat were established with thread embolization method firstly,and then PSD models rat were established with comprehensive chronic unpredictable mild stress(CUMS) and separately breeding on this basis.After the procedure,rats were subjected to sucrose preference test and open field test.At the postoperative eighth weekend,immunofluorescence technology was used to detect the proliferation changes of OX42 positive cells in the frontal lobe,hippocampus and amygdale.Results At the 29th day after CUMS,the sucrose solution consumption ((23.8±0.8) ％),horizontal movement distance of open field test ((63.0± 1.2) cm) and vertical movement distance ((25.0± 1.0) cm) in PSD group were significantly lower than those in normal group((31.2± 1.9) ％;(69.8±2.3) cm;(31.0± 1.6) cm) and depression group((31.0±1.4) ％;(70.2±2.4) cm;(30.8± 1.1) cm) (P＜0.05).The number of OX42 positive cells of frontal lobe,hippocampus and amygdale in PSD group((20.8±2.6);(20.2±1.3);(19.8±2.6))increased significantly compared with those of normal group((7.4±2.3);(8.0± 1.6);(9.4±2.1)),depression group((8.0±2.0);(7.8 ±2.2);(9.2±1.9))and stroke group((9.6±1.1);(9.4±2.2);(10.2±2.6)) (all P＜0.05).Conclusion The number of microglia in PSD group in the emotional disorders related brain areas(the frontal lobe,hippocampus and amygdale) increases obviously and the increased expression of microglia in the emotional disorders related brain areas may be responsible for the pathogenesis of PSD.

This study was designed to investigate inhibitory effects and possible mechanisms of snake venom tripeptide (pENW) on platelet adhesion in order to promote the development of a novel anti-platelet therapy. To study the inhibitory effects of pENW on platelet adhesion, washed platelets pre-incubated with pENW (116.5-466.2 μmol x L(-1)) were used to test the ability of platelet adhesion to fibrinogen. Effect of pENW on fibrin clot retraction was also tested. Effect of pENW on platelets viability was tested by MTT assay. Effect of pENW on reactive-oxygen species (ROS) levels of platelet was studied by flow cytometry assay. Calcium mobilization in Fura-2/AM-loaded platelets was monitored with a spectrofluorimeter. Cyclic guanosine monophosphate (cGMP) and cyclic adenosine monophosphate (cAMP), thromboxane A2 (determined as its metabolite thromboxane B2) were measured using enzyme immunoassay kits. Akt, ERK and p38 phosphorylation were tested by Western blot. The results showed that pENW inhibited platelet adhesion and fibrin clot retraction in a concentration-dependent manner without cytotoxicity. Intracellular cGMP and cAMP in both resting and thrombin-activated platelets were increased by pENW. In addition, pENW attenuated intracellular Ca2+ mobilization and TXA2 production in platelets stimulated by thrombin. As shown by Western blot assay, Akt, ERK and p38 phosphorylation in thrombin-induced platelet were attenuated by pENW. However, inhibitory effects of pENW had nothing to do with ROS. Thus, pENW exhibited a significant inhibition on platelet adhesion to fibrinogen, which means pENW could block the first step of thrombosis as while as retard the more stable clot formation. The mechanisms of pENW on inhibition platelet adhesion might be related to instant regulations, such as protein kinases.

Objective To investigate the effect of maternal exposure to bisphenol A(BPA) via drinking water on body weight of immature offspring during pregnancy and lactation. Methods The pregnant female ICR mice were exposed to BPA groups(2. 282 9,22. 829 0,228. 290 0 μg/L) by drinking water from gestational day(GD)0 till postnatal day (PND)21,water and dimethyl sulfoxide(0. 01%) were served as blank and vehicle control. Maternal body weight was recorded every three days during pregnancy. Weight of pups per litter was measured every three days during lactation. Body weight of offspring was taken notes every week till PND 42 after delactation. ResultsThere was no significant difference in pregnant maternal body weight, average numbers and body weight of pups per litter preweaning among all groups. The offspring weight of the high-dose group at PND 42 was increased compared with control groups(P<0.05). The weight of female offspring was not significantly different among all groups at PND 28~42. The male offspring weight of the middle/high group at PND 35 and all groups at PND 42 significantly was elevated(P<0.05,P<0.01),and the high group was most significant. Conclusion Body weight of immature offspring is affected,especially male offspring after delectation by pregnant and lactational BPA exposure.
