Different types of neurons are regularly dispersed on re tina. For finding the mechanism of eye and retina formation, it is important to know how t his regular pattern is formed during embryonic stage. It was claimed that multip le genes regulate the development of eye and retina. These genes regulate the de velopment of tissues and differentiation of cells in different parts of the visu al system during embryo development. Also, it was found that different tissues a nd differentiated cells cohere with each other both temporally and spatially to form the eye.

To obtain fusion protein of Mycobacterium bovis with high purity, the recombinant prokaryotic expression vector for Mb2277 gene was constructed and the immunogenicity of its products was initially investigated in the present study.A pair of primer was designed according the gene sequence Mb2277 from the genomic DNA of M.Bovis in GenBank. and was amplified by PCR using DNA of M.Bovis 93006 strain as template. The PCR product and pET-28a(+) was then digested by BamHⅠ and EcoR Ⅰdouble enzyme. To constructed a prokaryotic expression plasmid, the purified Mb2277 was cloned to pET28a(+). Then the recombinant plasmid was transformed into competent cell of E.coli BL21(DE3).The bacteria were induced by IPTG and its lysates were analyzed by SDS-PAGE and Western-blotting. In this way, the prokaryotic expression plasmid for M. bovis Mb 2277 protin was obtained, and a expression band with molecular of 25 ku could be found in SDS-PAGE analysis. As demonstrated by Western blotting this expression product showed excellent reactivity with rabbit immune sera against M. bovis.

A total of 104 patients with polycystic ovarian changes on ultrasound were divided into polycystic ovary syndrome (PCOS) and polycystic ovaries (PCO) groups according to their clinical symptoms and endocrine examinations.And 40 women with normal ovulation served as the controls.Ovarian volume (OV),ovarian stroma area (SA),ovarian total area (TA) and SA/TA ratio were measured by transvaginal uhrasonography.Their endocrine hormone levels were determined.Patients with PCOS showed significantly higher OV,SA,TA and SA/TA than those of PCO and control groups.SA/TA was positively correlated with testosterone.The median serum levels of anti-Mullerian hormone (AMH) and inhibit B in the PCO group were intermediate between those in control and PCOS groups.AMH and inhibin B of PCOS were higher than the PCO and control groups.It indicated that the levels of AMH and inhibit B were associated with the degree of polycystic ovaries and they could be used to differentiate PCOS and PCO.SA/TA is associated with the elevated serum testosterone of PCO.And SA/TA is an important ultrasonic parameter for diagnosing PCOS.

This study tested the effects of the gastrointestinal pulse train electrical stimulation with different parameters and at different locations on the neuronal activities of the lateral hypothalamus area (LHA) in obese rats in order to find the optimal stimulation parameter and location. Eight gastric electrical stimulations (GES) with different parameters were performed and the neuronal activities of gastric-distension responsive (GD-R) neurons in LHA were observed. The effects of stimulations with 8 parameters were compared to find the optimal parameter. Then the optimal parameter was used to perform electrical stimulation at duodenum and ileum, and the effects of the duodenal and ileac stimulation on the GD-R neurons in LHA were compared with the gastric stimulation of optimal parameter. The results showed that GES with the lowest energy parameter (0.3 ms, 3 mA, 20 Hz, 2 s on, 3 s off) activated the least neurons. The effects of GES with other parameters whose pulse width was 0.3 ms were not significantly different from those of the lowest energy parameter. Most gastric stimulations whose pulse width was 3 ms activated more LHA neurons than the smallest energy parameter stimulation, and the effects of those 3 ms gastric stimulations were similar. Accordingly, the lowest energy parameter was recognized as the optimal parameter. The effects of stimulations with the optimal parameter at stomach, duodenum and ileum on the LHA neuronal activities were not different. Collectively, gastrointestinal electrical stimulation (GIES) with relatively large pulse width might have stronger effects to the neuronal activities of GD-R neurons in LHA of obese rats. The effects of the GIES at different locations (stomach, duodenum and ileum) on those neurons are similar, and GES is preferential because of its easy clinical performance and safety.

Toll-like receptors (TLRs) family may play important roles in inflammatory bowel disease. This study examined the expression of TLR2, TLR4 and TLR9 in the colonic tissues of patients with ulcerative colitis (UC) and explored their roles in the pathogenesis of UC. Colonic biopsies were taken from the colon of 30 patients with mild or moderate UC (at active phase) and 10 healthy controls during colonoscopy. TLR2, TLR4 and TLR9 protein expression levels were immunohistochemically detected. The mRNA expression levels of TLR2, TLR4 and TLR9 were assessed by reverse transcription polymerase chain reaction (RT-PCR). The disease activity index (DAI), colonoscopic and histologic grades and fecal microbial flora were determined. Histological examination showed that the intestinal mucous membrane of UC patients underwent acute inflammation changes. Immunohistochemistry exhibited that the expression levels of TLR2, TLR4 and TLR9 in colon epithelia and inflammatory cells were higher in UC patients than in control group (P<0.01). The mRNA expression levels of TLR2, TLR4 and TLR9 were increased in UC patients but were not detected in the normal controls. Expression levels of TLR2, TLR4 and TLR9 were positively correlated, and bore close correlation with DAI, colonoscopic and histologic grades and fecal microbial flora. An important mechanism of UC might be that abnormal activation of mucosal immunity by intestinal dysbacteriosis caused dysregulation of TLRS that mediates innate immunity.
