Choroidal metastasis is one of the most common malignant tumors inside the eyes. It causes pain, hypopsia and some other related symptoms. It reduces the quality of the patients' life. It's significant for the patients to be detected and treated early, therefore they will have better vision and longer life. The treatments of choroidal metastasis are developing quickly. Both the vitreous cavity injection of targeted drug and gene therapy are hot topics of research. This paper summarizes the etiology, development, diagnosis and treatment of choroidal metastasis nowadays.

Myeloid differentiation protein-2(MD-2)can separately and simultaneously bind lipopolysaccharide(LPS)and toll-like receptor 4(TLR4)has been shown to play critical roles in mediated recognition responses to LPS by TLR4 and signal transduction induced by LPS.MD-2 can be bound by LPS,not TLR4.The cells have no responsiveness or weak responsiveness to LPS without MD-2.MD-2 can be secreted into blood plasma,formed soluble MD-2 and remotely regulated cells that contained TLR4 without MD-2.MD-2 has been shown to play important roles in endotoxin signal transduction.MD-2 is a small molecular,short nucleic acid fragment,easily regulated should become a new potential anti-inflammatory target.

Objective To explore the effect of age on neurogenesis of dentate gyrus granule cell and the impact on differentiation of newborn cells in rats.Methods SD rats were selected and divided into 5 groups according age of 7,14,28,60,180 d(n=8),and the neurogenesis of dentate gyrus granule cell in hippocampus with normal development was detected,using 5-bromo-BrdU(BrdU) labled newborn neuron and ?-tubulin protein(TuJ1) and glial fibrillary acidic protein(GFAP) labeled glial cells,and understood the newborn cells to neurons and glial cell differentiation ratio.Results Neurogenesis was found in dentate gyrus granule cell layer with hippocampus of all different age rats.Various forms of cells with a larger nucleus that were round,oval,diamond were distributed over the entire granule cell layer.BrdU-positive cells within each group were 158.07?5.37,141.28?7.27,116.93?9.24,76.56?6.88,41.42?4.45,the number of BrdU-positive cells were reduced with the growth of rats(P0.05);4%-5% newborn cells expressed GFAP.In addition,some of the BrdU-positive cells at the same time did not express TuJ1 or GFAP.Conclusions There are neurogenesis in dentate gyrus granule cell in rats of different age.The new born cells mostly differentzate into granule neuron cell.The capability of cell proliferation are decreased with the growth of age.

OBJECTIVETo explore the effect of Qingyi Granule (QYG) on high mobility group box-1 (HMGB1) expressions in liver and renal tissues of severe acute pancreatitis (SAP) rats.

METHODSFifty-four Sprague-Dawley (SD) rats were divided into the sham-operation (SO) group, the SAP group, and the QYG group according to random digits table. Rats in the SAP group were induced by injecting 5% sodium taurocholate (STC). Liver and renal pathological changes were observed by HE staining. Serum contents of amylase (AMS), MDA, IL-1, and HMGB1 were detected by ELISA. HMGB1 protein expressions in liver and renal tissues were tested by immunohistochemistry. HMGB1 mRNA expressions in liver and renal tissues were detected by reversed transcription PCR.

RESULTSThe pathological scores, serum levels of AMS, MDA, IL-1 and HMGB1, and protein and mRNA HMGB1 expressions in liver and renal tissues were increased more obviously in the SAP group than in the SO group (P < 0.05, P < 0.01). All of them could be down-regulated by QYG intervention, with the most significant effect seen at 72 h (P < 0.05, P < 0.01) in a time-effect relationship.

CONCLUSIONSHMGB1 participated in SAP complicated liver and renal injuries. QYG could effectively inhibit HMGB1 expressions, thereby attenuating SAP complicated liver and renal injuries.

OBJECTIVETo analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).

METHODSA total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.

RESULTSChewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).

CONCLUSIONSPain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.

Objective To explore the liver pathology from live related liver transplatation(LRLT) of Wilson′s disease(WD) in children,and evaluatethe indication of LRLT.Methods The sample of this study,including the donater and patient,came from the LRLT. It was observed with HE,MASSON,Timm′s and Rubeanic staining.Results With HE and MASSON stainning,hepatocyte showed degeneration,fiber hyperplasic and false lobule formed;Timm′s and Rubeanic stainning showed typical black deposit of granules and conglomerations.Liver pathology revealed that liver cirrhosis appeared,and it was diffrentent from Child Pugh.Conclusions It is of great significance that the liver pathology is useful for the treatment of WD.If liver pathology supportes,the indication of LRLT can be measurably broadened.

Objective To investigate the osteoclast′s function levels in infants and toddlers and the relationship between the osteoclast function and sex,age,body length,body weight and body mass index(BMI).Methods Sixty-eight children(37 boys and 31 girls,aged from 1 to 36 months) were studied.All of the children were in good health.These children were divided as infants group and toddlers group according to their age.Just before the samples were collected,the children′s body weight,body length were measured and the BMI were calculated.Two biochemical markers,such as serum tartrate-resistant acid phosphatase 5b(TRAP5b) and urine deoxypyridinoline(DPD) were measured.Results The difference of serum TRAP5b concentration between infants and toddlers was significant at the level of P

Based on the standards for mental developmental re-tardation set up by WHO in 1985,by applying IQ andadaptation to social behavior as indexes for observa-tion with testing methods for intelligence commonlyaccepted,we have observed the effects in 128 suchcases treated by combined use of acupuncture,adhe-sive—pressing therapy at auricular points and drugplastering at points.Results showed that our therapyis conducive to the improvement of intelligence in suchcases.

Background:Intestinal ischemia-reperfusion( I/R)is a surgical abdomen,which not only leads to intestinal tissue necrosis,but also induces systemic inflammatory response,resulting in a serious impact on other organs and tissues. Aims:To investigate the role and mechanism of rosiglitazone( ROS)on intestinal I/R injury. Methods:Eighteen male C57BL/6 mice were randomly divided into three groups:sham operation group,I/R injury group and ROS pretreatment group. Mice in ROS pretreatment group received ROS(0. 3 mg/kg,IV)30 minutes before I/R injury. I/R injury model was established by clamping superior mesenteric artery for 30 minutes,followed by 4 hours reperfusion. All the mice were sacrificed. The pathology of intestinal tissue was examined by HE staining. The mRNA expressions of tumor necrosis factor( TNF )-α, interferon(IFN)-γ,interleukin( IL)-1β,transforming growth factor( TGF)-β and Smad3 were measured by real-time quantitative PCR. The protein expressions of TGF-βand Smad3 were measured by Western blotting. Serum levels of TNF-α, IFN-γand IL-1βwere measured by ELISA. Results:Compared with the sham operation group,pathological score of small intestinal mucosa in I/R injury group was significantly increased(P<0. 05),and the mRNA expressions of TNF-α,IFN-γand IL-1β were significantly increased( P < 0. 05 ),the mRNA and protein expressions of TGF-β and Smad3 were significantly increased(P<0. 05),the serum levels of TNF-α,IFN-γand IL-1β were significantly increased(P<0. 05). With the pretreatment of ROS,all the above-mentioned indices were significantly ameliorated(P<0. 05). Conclusions:ROS pretreatment can attenuate intestinal I/R injury by inhibiting TGF-β/Smad3 signal pathway to reduce inflammation.
