The expression patterns of gastrin(Gas),β-endorphin(End).somatostatin(Ss),glucagons(Glu),and 5-hydroxytryptamine (5-HT)cells in the duck bursa of Fabricius were studied by the immunohiswchemicai method associated with image analysis.The resuhs showed that the Gas-positive cells with high intensity wrte seen in the follicle-associated epitllelium (FAE),the End with medium intensity in the interfollicular epithelium,the End,Gas and 5-HT with medium or high intensity in the cortex of lymphoid follicles.and the Gas with high intensity in the medulla of lymphoid follicles.Both SS and Gh showed negative reaction.The pre-sent results demonstrated that the Gas,End and 5-HT cells are differentially expressed in the different parts of the duck bursa.The positive cells distributed in the cortex of lymphoid follicles might favour exerting their influence via an endocrine, autocrine or paracrine pathways on the development of B cells.

Objective Observed the mobilization effects、 the safety and feasibility of autologous circulating blood stem cell by G-CSF in acute myocardial infarction (AMI). Methods 45 patients with AMI were randomly allocated to receive either inclusive type Granulocyte Colony-Stimulating Factor (G-CSF), to mobilize the stem cell. The patients received the dose of G-CSF 300?g-600?g/day, by hypodermic injection, and the duration of applying G-CSF was 5 days. In the process of the mobilization of the circulating blood stem cell, prior to applying G-CSF and on the 3rd、4th、5th、6th、7th after applying G-CSF, the white blood cell (WBC) and CD34+ cell count in the circulating blood should be observed; and the following side effects also should be paid attention to, such as: bone pain, tetter, fever, gastrointestinal effects( nausea 、vomit、 coprostatis ),deteriorated of angina or heart failure and some rare effects(spontaneous spleen rupture, severe purulent infection, hypercoagulable state, autologous immune diseases). Results Prior to applying G-CSF and the 3rd、4th、5th、6th、7th after applying G-CSF, the counts of WBC were (8.42?2.59)?10 9/L、(31.28?8.34)?10 9/L、(35.24?9.38)?10 9/L、(37.03?13.07)?10 9/L、(35.34?14.68)?10 9/L、(20.35?9.22)?10 9/L;the counts of CD34+ cell were (14.89?11.46)?10 6、(67.78?50.88)?10 6、(124.79?136.13)?10 6、(208.92?206.97)?10 6、(206.10?184.57)?10 6、(66.63?56.56)?10 6;The peak of curve that WBC and CD34 + cell count changed with applying days was on the 5th .The count of CD34 + cell in the circulating blood was positive referent with the count of WBC in the circulating blood(r=0.835);was not reference with age、 sex、body weight、and the onset time of AMI. There were total 17 complications during the mobilization of circulating blood stem cell. The incidence of complications during mobilization is 37.8%(17/45), including bong pain being 15.6%(7/45)、fever being 6.7 %(3/45)、pale being 4.4 %(2/45)、tetter being 4.4 %(2/45)、deterioration of heart failure being 4.4 %(2/45),spleen thrombosis being 2.2 %(1/45).No death happened. Conclusion : In patients with AMI, the mobilized peak of WBC and CD34 + cell counts changed with applying days was at the 5th, and the count of CD34 + cell in the circulating blood was positive referent with the count of WBC in the circulating blood(r=0.940),was negative referent with body weight of patients(r=-0.398). And mobilization of autologous circulating blood stem cell was feasible and safe.

Objective To investigate the possible mechanisms of enhancing angiogenesis and arteriogenesis through the oberservation of the effect of gene transfer of angiopoietin-1 (Ang1) on its receptor Tie2 in rat models of acute myocardial infarction. Methods Myocardial infarction was induced in rats by left anterior descending artery ligation. Naked plasmid DNA encoding human angiopoietin-1 (phAng1) was delivered into the ischemic area (group A) by intramyocardial injection. On day 3, 7, 14 and 28 after the injection, the mRNA expression of Tie2 and its changes with time were determined by RT-PCR. The number of vessels and arterioles was examined by immunohistochemistry. The collagen was evaluated by Masson staining. Results RT-PCR showed that mRNA expression levels of Tie2 in group A were significantly higher than those in the control group, reached the highest level on day 7 post-injection, and gradually declined to normal level 28 days later. On day 7, 14 and 28, the vessel count showed the number of blood vessels (angiogenesis and arteriogenesis) in group A was greater than that of the control group at the same timepoint and the infracted myocardium in group A was significantly less than that of the control group. Conclusion Gene transfer of phAng1 enhances angiogenesis and arteriogenesis in acute myocardial infarction and reduces the infraction area probably by upregulating the expressions of Tie2 receptor.

Purpose There is no agreement for contrast enhanced ultrasound (CEUS) in differential diagnosis of benign and malignant thyroid nodules. This paper aims to evaluate the diagnostic value of the conventional and contrast-enhanced ultrasonography in the diagnosis of thyroid nodule by meta analysis. Materials and Methods Literature search was performed in PubMed, CNKI and Wanfang databases to identify relevant English and Chinese literatures by using pathological results as the gold standard from January 1990 to September 2014. The quality of each selected study was evaluated by QUADAS. The pooled weighted sensitivity, specificity and the corresponding 95% CI were calculated. Summary receiver operating characteristic curves (SROC), area under curve (AUC) and the Q* index were also calculated. Results A total of 14 literatures (1970 nodules) were included, the pooled weighted sensitivity and specificity of conventional ultrasonography were 0.74 and 0.70; those of contrast-enhanced ultrasonography were 0.86 and 0.82. The AUC by using the two methods were 0.84 and 0.93, respectively, and the Q* index were 0.77 and 0.86, respectively. Conclusion In the diagnosis of thyroid nodule, the accuracy of contrast-enhanced ultrasonography is better than conventional ultrasound; however, both of them have high clinical value in the diagnosis of thyroid nodule, thus they are helpful in avoidance of unnecessary surgical treatment in patients with thyroid disease.
