?AlM: To discuss the differences in accommodative lag of different stimulation between the adolescent myopes who wore rigid gas permeable contact lens ( RGPCL ) and spectacles for one year.
?METHODS: Totally 85 myopes between 10-16y were enrolled in the study. Every subject was examined with the visual function test, medical optometry, corneal topography and ocular health check etc. of eyes. According to the above measurements and the compliance of children and their parents, 41 subjects were selected to wear RGPCL, 44 subjects were chosen to wear spectacles. Based on maximum plus to maximum visual acuity ( MPMVA) , accommodative lag was determined by dynamic retinoscopy method in two groups. The subjects were examined once every 3mo, accommodative lag was measured again using the same method for comparative analysis after one year. Wearing a year later, myopia progression of the two groups was measured and compared.
?RESULTS: There was no significant difference between two groups of initial accommodative lag (P>0. 05). After wearing one year, there was also no significant difference between the accommodative lag examined and the initial lag in RGPCL group (P>0. 05), the results demonstrate significant difference between the accommodative lag examined after wearing one year and the initial lag in spectacles group ( P < 0. 05 ). One year later, the differences were significant in accommodative lag between RGPCL and spectacles wearers stimulated by 2D, 3D and 4D ( P < 0. 05 ), and the accommodative lag increased with increasing stimulation in both groups. After wearing a year, the myopia progression of RGPCL group was less than spectacles wearers, and the differences were significant (P<0. 05).
?CONCLUSlON:After wearing RGPCL and spectacles one year in high accommodative stimulus, there is an obviously decreased in accommodative lag in RGPCL group, which suggests that RGPCL can control the progression of myopia in adolescents. The accommodative lag of the two groups increase obviously with increasing stimulation, which suggest that the adolescents need keeping good habits of reading.

OBJECTIVETo explore the analgesic effect of Zhixin Formula (ZF) and its effects on spinal glial fibrillary acidic protein (glial fibillary acidic protein, GFAP, a marker of astrocyte) , CD11b (a maker of microglia), Toll like receptors (TLR2 and TLR4) and nuclear factor κB (NF-κB) in bone cancer pain model rats.

METHODSTotally 20 male SD rats were randomly divided into the blank control group and the bone cancer pain group, 10 in each group. The bone cancer pain model was induced by injecting ascites tumor fluid containing 3 x 10(3) Walker256 cell line from the left tibia. Ethological tests, X-ray test, and HE staining were performed to confirm a successful modeling. After model was successfully established, 70 male SD rats were randomly divided into seven groups, 10 in each group: the blank control group, the bone cancer pain group (as the model group), the Western medicine (WM) group (Tramadol Hydrochloride), the high dose ZF group, the middle dose ZF group, the low dose ZF group, and the Chinese medicine (CM) group (Wulin Zhitong Capsule). Fourteen days after modeling, rats in the high, middle, and low dose ZF groups were administrated by gastrogavage with 9, 4.5, and 2.25 g/kg ZF water condensed preparation respectively, once a day for seven consecutive days. On day 21 MS typical protein expressions including GFAP, CD11b, TLR (2,4) and NF-κB from cornu dorsal medullae spindis L4-L5 were detected by immunohistochemistry, reverse transcription-polymerase chain reaction (RT-PCR) and Western blot.

RESULTSCompare with the blank control group, increased weight in the model group was slow and showed a decreasing trend (P < 0.01), spontaneous ambulatory pain score (SAPS) obviously increased (P < 0.01), paw withdrawal threshold (PWT) obviously decreased in the model group (P < 0.05, P < 0.01). Results of lateral tibial X-ray and HE staining showed obvious changes and damage occurred in bone structures of rats in the model group. Immunohistochemistry showed that GFAP expression significantly increased in the model group (P < 0.05). Protein levels of NF-κB also significantly increased in the model group (P < 0.05). Compared with the model group, CD11b expressions obviously decreased in the middle and high dose ZF groups (P < 0.01). Meanwhile, protein expressions of TLR2 and TLR4, as well as NF-κB also obviously decreased (P < 0.05).

CONCLUSIONZF had analgesic effect, which might be probably related to inhibiting proliferation and activation of gliocytes, as well as activation of TLRs and NF-κB.

OBJECTIVETo investigate the influence of glucocorticoid on phenotype of thymic dendritic cells in mice and to investigate the protective effect of Yougui Pill (YGP) on it.

METHODSBALB/c mice allocated in the group A and B were treated respectively with 10 mg/kg hydrocortisone, alone and combined with 20.81 g/kg YGP. The control mice were treated with normal saline. The changes before and after treatment of I-A(d) and H-2K(d) antigen presentation molecules expression in CD11c(+) and CD45(+) thymic dendritic cells of mice were analyzed by flow cytometry assay, and the expression of intercellular adhesion molecule-1 (ICAM-1) and leukocyte function-associated antigen-1 (LFA-1) mRNA in thymocytes were determined by RT-PCR as well.

RESULTSThe percentage of I-A(d+) and H-2K(d+) in CD11c(+) in Group A after treatment was 46.77 +/- 4.32% and 64.34 +/- 7.69% respectively, as compared with those in the control group (65.81 +/- 7.69% and 31.88 +/- 5.01%), the percentage of I-A(d+) was lower and that of H-2K(d+) was higher significantly (all P <0.01). Meantime, the expression of ICAM-1 and LFA-1 in thymocyte in Group A (30.11 +/- 2.51% and 30.40 +/- 3.77%) was significantly lower than that in the control group (46.35 +/- 3.34% and 47.28 +/- 2.91%) respectively (P <0.01). Changes in Group B showed that treated by hydrocortisone in combination with YGP, the above-mentioned hydrocortisone-induced changes could be obviously reversed, the outcome of CD11c(+) I-A(d+) was 54.19 +/- 5.08%, ICAM-1 33.97 +/- 2.04% and LFA-1 34.80 +/- 2.92%, the difference between the two treated groups in these indexes all showed statistical significance (P <0.05).

CONCLUSIONGlucocorticoidcan inhibit the expression of major histocompatibility complex class II antigen molecule, but promote the expression of major histocompatibility complex class I in CD11c(+) and CD45(+) dendritic cells, down-regulate ICAM-1 and LFA-1 transcription, while the tonifying yang recipe, YGP, has a dominant protective effect against the above actions of glucocorticoid.

Objective To explore the association of ubiquitin-specific proteases 24 (USP24) gene polymorphisms with susceptibility to sporadic Parkinson's disease (PD) in the Han Guangdong population. Methods From August, 2006 to January, 2014, single nucleotide poly-morphisms (SNPs) of rs12138592 and rs6671533 in the intron region of USP24 were genotyped in 200 patients with sporadic PD and 200 healthy controls using the SNaPshot technique. Results There was significant difference in the allele and genotype frequency of rs12138592 between the patients and the controls (P<0.01), and no significant difference was found in the allele and genotype frequency of rs6671533 (P>0.05). Conclusion The SNP of rs12138592 in the intron region of USP24 is associated with the susceptibility to sporadic PD in the Han Guangdong population, and the A allele may contribute a protective roles to PD.

A set of primers amplified the VP1 gene of foot-and-mouth disease vims (FMDV) was designed and synthesized. A reverse transcription-polymerase chain reaction (RT-PCR) technique detected the RNA of FMDV was established after selecting the best purification method, reagents and reaction conditions. Samples of fresh milk, lymph node, spinal cord, vesicular skin, milk powder, cotton swab, mouse and meat in daughter-house were detected by RT-PCR, positive rates were41.4% (24/58), 13.33% (2/15), 20% (1/5), 100% (1/1), 100% (1/1), 37.5% (12/32), 100% (2/2) and 10% - 70%, respectively. However, positive rate of cockroach detected by RT-PCR was 0. The results showed that the established FMDV RT-PCR technique provided a more sensitive, specific and reliable method for diagnosis and epizootic study of the foot-and-mouth disease.

Objective To evaluate the diagnostic value of detection of IgM antibodies to EV71-infection patients,and compared characterisation of RT-PCR,IgM capture ELISA and neutralization test.Methods Virus RNA,neutralization titer and IgM antibody in 115 EV71-infection patients were detected by EV71 real-time RT-PCR kit( EV71-PCR kit),neutralization test,and EV71 IgM-capture ELISA kit (EV71-IgM kit),respectively.Results Using EV71-IgM kit,the detection rate was 80.9％ (93/115,95％ CI:72.5-87.6) among the 115 EV71-infection patients,and was 2.6％ among the 228 healthy children.Simultaneously,sera collected after 1-2 day of disease onset showed an IgM positivity of 70.4％ (38/ 54).The positive rate of EV71-PCR among these patients was 82.6％ (95/115,95％ CI:74.4-89.0),so there was no statistically significant differences between it and EV71-IgM kit.In addition,the detection rate in EV71-infection patients could increase to 92.2％ by combined detection of EV71-PCR and EV71-IgM kit.Conclusion EV71-IgM kit was a rapid and valuable way for the early diagnosis of EV71 infection,and could significantly improve detection rate for EV71 infection by combining with EV71-PCR kit.

Identification of genetic risk factors is the hotspot of adolescent idiopathic scoliosis (AIS). Through candidate gene approach and genome-wide association studies (GWAS), some genes were preliminary identified. To review AIS related genes,and construct the gene network map of AIS gene. We searched on NCBI PubMed and Web of Science database using search terms "adolescent idiopathic scoliosis" and "gene", to classify induction genes. We then constructed gene diagram using string-db. We found 35 AIS genes relating to connective tissue, nervous system active substances, melatonin synthesis and metabolism, puberty and growth, and genes whose function is unknown. Gene diagram shows that a network relationship between gene and other genes,in which IL6, ESR1, ESR2, VDR, TGFB1, IGF1 gene may as the key gene about AIS' genetic mechanism. Two sites of 3 GWAS results outside the network, it is suggesting new pathway that need to be explored. The study about AIS susceptibility gene is still preliminary, requiring in-depth research to identify the new networks.
