●METHODS: Totally 60 patients with cataract in our hospital from November 2011 to September 2013 were included as the observation group, and 60 patients with eye traumas were as the control group. The serum, aqueous humor and tear lL - 2, slL - 2, NO, TAC, and SOD of two groups were detected and compared, and the detection levels of patients with different stages were compared.
●RESULTS: The serum, aqueous humor and tear lL-2, TAC, and SOD of observation group were all lower than those of control group, the slL-2 and NO were all higher than those of control group. The serum, aqueous humor and tear detection levels of patients at different stages had obvious differences, and the aqueous humor lL - 2 were lower than those of serum and tear, the slL-2 were higher than those of serum and tear, with statistically significant differences.
●CONCLUSlON: The change of serum, aqueous humor and tear lL-2, slL-2, NO, TAC, and SOD of patients are all great, and the influence of the stages for those indexes are great too, the inflammatory response state of aqueous humor are more obvious.

With the existence of capsules,lens regeneration occurs in some mammals after extracapsular lens extraction.It is usually thought that lens regenerates from resident lens epithelial cells (LECs) in the capsule.However,lens regeneration dose not mean simple redupilication of development,and transparency of the lens is affected by irregular growth,migration and transdifferention of the resident LECs.Previous studies mainly focus on the dysplasia of LECs,but update theory about lens regeneration is proposed to be associated with stem cells.Some views and suggestions in lens regeneration are concerned in current researches to better illuminate the mechanism and therapy of posterior capsular opacity.

Aiming at the missing links in traditional models of ideological and political course in medical colleges of our country,we built the3+3+3model teaching paradigm,and selected students of medical laboratory and pharmaceutical profession as the research object to put this mode into practice.We issued questionnaires and test to evaluate teaching effect.The study showed that this model could make up for the loss of traditional teaching pattern,which verified the effectiveness and the significance of the teaching reform.The shortcomings as well as its future direction was also made clear.

AIM: To investigate the effects of apelin-13 on proliferation, migration and capillary-like tube formation of a monkey choroid / retinal endothelial cell line, RF/6A, to clarify whether apelin-13 could promote retinal angiogenesis in vitro.METHODS: RF/6A cells in good conditions were administrated with DMSO (the control group), apelin-13 at 0.1μmol/L (low dose group) or apelin-13 at 1μmol/L (high dose group).Cell proliferation, migration and capillary-like tube formation were detected by using the MTT assay, scratch assay and matrigel assay, respectively, at 24h after plating the cells.RESULTS: Cell proliferation was promoted in both low and high dose apelin-13 groups compared to the control cells (P<0.05);the cell migration distance of both apelin-13 groups was significantly greater than that of the control group (P<0.05);and the number of capillary-like tube structures of both apelin-13 groups was significantly larger than that of the control cells (P<0.05).In addition, cell proliferation, migration and tube formation increased as the concentration of apelin-13 increased.CONCLUSION: Apelin-13 could obviously promote the angiogenesis capacity of RF/6A cells, suggesting that apelin-13 was an important pro-angiogenic factor in retinal endothelial cells.

A protocol for enrichment and adsorption of karyocyte from whole blood by using magnetic nanometer beads as solid-phase absorbents was presented. The PCR amplification could be accomplished by using the nanobeads with karyocyte as template directly and the PCR products were applied on an oligonucleotide array to do gene typing. The HLA-A PCR amplification system and a small HLA-A oligonucleotide microarray were applied as the platform and an experiment protocol of separating karyocyte from whole blood using the magnetic nanometer beads (Fe2O3) were set up. The experimental conditions were also discussed. It showed that pH level of PBS eluent, Taq enzyme quantity and fragment length of products could influent the amplification results, and the magnetic nano-beads could succeed in sample preparation in microarray to provide a promising way in automatic detection and lab-on-a-chip.

The first case of acquired syphilitic skull osteitis accompanied by syphilitic meningitis in China is reported.A 55-year-old female presented with a persistent distending pain of the frontal and occipital regions of the skull for two months.T1 weighted magnetic resonance imaging(MR1) showed muhiple lesions in the skull and linear enhancement of the meninge near the lesions.The serum and cerebrospinal fluid (CSF) were positive for Treponema pallidum particle agglutination assay (TPPA) and rapid plasma reagin circle card test(at the dilutions of 1∶32 and 1∶4 respectively).The levels of leukocyte and protein were 10 ×106/L and 0.82 g/L respectively in CSF.TP DNA was detected in the calvarial periosteum.Histopathological examination of the frontal bone showed focally destructive osteolytic lesions with obscure texture of the bone,hyperemia around the destructive bone tissue and in dura mater-like tissues,proliferation of interstitial fibrous tissue,swelling of endothelial cells and inflammatory infiltration predominantly composed of abundant plasma cells.After managed with routine treatment regimen for neurosyphilis,her headache was relieved 3 days later,nearly disappeared 15 days later,completely disappeared 30 days later.No similar headache recurred.A 5year follow up demonstrated a satisfactory long-term and short-term outcome.She was finally diagnosed with syphilitic skull osteitis complicated by syphilitic meningitis.

OBJECTIVETo investigate the effect of oligochitosan in promoting intestinal absorption of protoberberine alkaloids in extracts from Corydalis saxicola total alkaloids.

METHODThe in vitro single-pass intestinal perfusion model in rats was established to study the changes in absorption kinetic parameters of dehydrocavidine, berberine hydrochloride and palmatine chloride in C. saxicola total alkaloids after the addition of different concentrations oligochitosan and evaluate the effect of oligochitosan in promoting intestinal absorption of the drugs.

RESULTThe concentration of oligochitosan had different effects on the absorption rate constant (Ka) and apparent permeability coefficient (Peff) of the three active component in rat intestines. Ka and Peff in 0.5% oligochitosan group significantly increased, indicating a stronger effect in promoting the absorption.

CONCLUSIONOligochitosan has a certain effect in promoting the intestinal absorptions of protoberberine alkaloids in C. saxicola total alkaloids.
