AlM: To evaluate the effect of rigid gas permeable contact lens ( RGP ) in correcting high myopia and astigmatism.METHODS: Forty-one patients ( 65 eyes ) with myopia (-9. 03 ± 6. 19DS, maximum -23. 00DS) and astigmatism (-1. 41 ± 1. 32DC, maximum -5. 50DC) were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.RESULTS:Sixty-five eyes were fitted with RGP (-9. 92± 5. 96DS). RGP base curve ( BC) was majorly located within the range 7. 20 ~8. 25mm. 46. 2% eyes with RGP achieved 1. 0 ( BCVA ) and 80. 1% achieved above 0. 6 ( BCVA) . However, with spectacles, the percent was 28%(1. 0) and 60% (>0. 6), respectively. BCVA of RGP was 0. 81 ± 0. 22, but BCVA with spectacles was 0. 66 ± 0. 28, there was statistical significance (P<0. 01). There were 40 eyes (62%) fitted with RGP whose vision were enhanced more than 1 line, 24 eyes ( 37%) whose vision were not changed and 1 eye (2%) whose vision were dropped 1 line.CONCLUSlON:RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.

Objective To analyze the clinical features and pulmonary radiological findings of primary anti-neutrophil cytoplasmic antibody(ANCA)-associated vasculitis (AAV).Methods Clinical data of 271 ANCA positive primary AAV patients admitted in Shanghai Ruijin Hospital from January 2003 to November 2015 were retrospectively analyzed.Among 271 patients,there were 211 myeloperoxidase (MPO)-ANCA positive cases (MPO subgroup),52 proteinase 3 (PR3)-ANCA positive cases (PR3 subgroup),and 8 dual positive cases (dual subgroup) according to ANCA classification.The demography,clinical characteristics,pulmonary radiological manifestation and renal function were compared among three subgroups.Results MPO subgroup had more renal (x2 =4.968,P =0.026) and constitutional symptoms (x2.=8.901,P =0.003) than PR3 group,while PR3 group had more ENT symptoms (x2 =19.843,P ＜ 0.001),cough (x2 =6.623,P =0.010),hemoptysis (x2 =8.656,P =0.003),dyspnea (x2 =5.127,P =0.024),buccal and ocular mucosal symptoms (x2 =4.818,P =0.028) than MPO group.In lung radiology,interstitial manifestations were displayed more frequently in MPO than PR3 group (x2 =4.237,P =0.040),while pulmonary nodules was more frequent in PR3 than MPO group (x2 =4.503,P =0.034).Dual subgroup tended to have more nervous,respiratory and renal impairment.Renal function showed that MPO subgroup had higher creatinine (Z =-5.529,P ＜ 0.001),urea (Z =-4.646,P ＜ 0.001) and uric acid levels (Z =-2.331,P =0.020) than PR3 subgroup.Dual subgroup had higher creatinine (Z =-3.251,P =0.001) and urea (Z =-2.882,P =0.004) levels than PR3 subgroup,but there was no difference with MPO subgroup.Conclusion There are significant differences in both clinical and pulmonary radiological manifestations between the MPO and PR3-ANCA subgroup of primary AAV.

Objective The interaction between anti-neutrophil cytoplasmic antibaties (ANCA) and receptors at the Fc portion of immunoglobulins (FeγR) is central in the pathogenisis of primary systemic small vasculitis. The aim of this study is to investigate the role and clinical value of ANCA on the expression of neutrophils FCγRⅡ/Ⅲ (CD32/CD16). Methods ANCA IgG was prepared from the sera of patients with active We-gener's granulomatosis (WG) and microscopic polyangiitis (MPA). Neutrophils were isolated from the blood of healthy volunteers. The expression of CD32/CD16 on neutrophils was assessed by flow cytometry after stimulated by ANCA for 1 hour. We compared the expression of CD32/CD16 between 18 primary systemic small vaseulitis (PSV) patients and 35 healthy volunteers. Furthermore, the correlation was also be analyzed between the expression of CD32/CD16 and Birmingham vasculitis activity score (BVAS). Results The expression of CD16 was significandy elevated by ANCA (Mnx 67±23 vs 54±21, P<0.01 ). The expression of CD16 was higher in patients than in healthy volunteers (Mnx 62±12 vs 53±10, P<0.01), which was in correlation with BVAS (r=0.728 86, P<0.01). But no such correlation was found for CD32 . Conclusion ANCA may play a role in the pathogenesis of PSV by modulating the expression of the FCγR. Monitoring the expression of CD16 on neutrophils is helpful for the evaluation of PSV activity.

Institute of Pediatric,Suzhou University Affiliated Children's Hospital,Suzhou 215003,China Objective To explore the long-term effects of physical exercise on neonatal seizure-induced learning,memory deficit and the expression of zinc transporter-3(ZnT3)in rat hippocampus.Methods Sprague Dawlev rats aged 6 days were randomly divided into a recurrent-seizure group(RS)and a control group. At postnatal dav 6(P6),the recurrent seizures were induced by inhalation of the volatile agent flurothyl once a day for consecu tive 6 davs.The rats in the control group were placed in the container for an equal period of time as those in the RS group without exposure to flurothyl. Y-maze test was performed to evaluate learning and memory capacity at postnatal day 29 to 35 and 61 to 67,respectively.During the period of postnatal day 51 to 56,all the animals in the RS andcontrol groups were subject to a 30-minute daily aerobic exercise program for consecutive 6 days.All the animals weresacrificed at postnatal day 78,and the in situ hybridization method was used to detect the expression of ZnT3 mRNA in hippocampus. Results ①The number of trials needed for getting correct response to the electric stimulation in the first Y-maze test was(60±14.1)and(37.5±17.2)for the RS and control groups,respectively(P＜0.05),while that in the second Y-maze test carried out 24 hours later was(27.5±14.1)and(21±11.01)for the RS and the control groups,respectively(P＞0.05).②Memory test revealed no significant difference between the RS and thecontrol groups(P＞0.05).③In situ hybridization detection showed that the expression of ZnT3 mRNA in hippocam pus was not significantly different between the two groups.However,there showed a significant difference between the dentate gyrus and CA3 in the RS group with regard to the expression of ZnT3 mRNA(P＜0.05). Conclusions Physical exercise improves the learning capacity of neonatal seizure-induced cognitive deficit and might have effects on the regulation of zinc transporter gene expressions in hippocampus.

Objective To investigate the effects of tg19320,a small peptide,interfering with IgG-FcγR interaction on the adhesion of neutrophils to endothelium and the expression of intercellular adhesion molecule 1 (ICAM-1)in endothelial cells and its possible mechanism.Methods Tg19320 was prepared by solid-phase peptide synthesis.ANCA IgG was isolated from the serum of active ANCA-associated systemic vasculitis(AASV)patients.When primary human umbilical vein endothelial cells(HUVEC)grew into connuence in cytokine-free eonditions,the cells were stimulated with TNF-α,human normal IgG,ANCA IgG and ANCA IgG+tg19320 respectively.HUVEC were pretreated with tg19320 for 45 minutes before being stimulated by ANCA IgG.Non-activated neutrophils was added to treat HUVEC and adhesion was measured by cell count.The expression of ICAM-1 mRNA and protein was assessed by real-time PCR and Western blot respectively.Soluble ICAM-1(sICAM-1)was determined using ELISA technique.Phosphorylation of IκB-α was assessed by Western blot. Results ANCA IgG significantly up-regulated the expression of ICAM-1 in HUVEC and promoted sICAM-1 release(P＜0.05),and TNF-α enhanced the effect of ANCA.These effects were almost completely abolished by tgl9320 both at protein and mRNA level.Furthermore,ANCA IgG increased the IκB-α phosporylation in HUVEC and tg19320could inhibit the effect. Conclusions ANCA IgG can modulate the expression of ICAM-1 and sICAM-1 release in endothelial cells.FcγR probably play a critical role in the ICAM-1 expression up-regulated by ANCA,which is mediated in part through NF-κB signaling pathway.Tg19320 has protective effect on endothelium in AASV in vitro.

Objective Despite regular treatment,antineutrophil eytoplasmie antibodies(ANCA)asso- ciated systemic vasculitis(AASV),in which the role of Fc?Rs has been established,are still associated with significant long-term mortality and remain an important cause of end-stage renal failure.ANCA plays an im- portant role in the pathogenisis of primary systemic small vessel vasculitis(PSV)by their potential to activate neutrophils.Because the interaction between ANCA and its receptors on the Fc portion of immunoglobulins (Fc?R)on neutrophils is essential in the activation process,we investigate the inhibitory,effect of tg19320 on ANCA induced activation of neutrophils,which is a tetrameric tripeptide that interferes with IgG/Fe?Rs in- teraction.Methods We prepared tg19320 by solid-phase peptide syntbesis.The binding between tg19320 and human IgG was assessed by enzyme-linked immunosorbent assay.The biological activity of tg19320 to intefere with FcF?receptor recognition was identified by rosette formation assay.ANCA IgG was prepared from the sera of active Wegener's granulomatosis(WG)and microscopic polyangiitis(MPA)patients.Neu- trophils isolated from the blood of healthy volunteers were primed with TNF-?(2 ng/ml)and then incubated with ANCA IgG(200?g/ml),or pretreated with tg19320(2.5 mg/ml)and then added with ANCA IgG.Su- peroxide burst of neutrophils was determined by Ferri-cytochrome reduction assay.Results We found that tg19320 bound tightly to human IgG in a dose dependent manner and the inhibition of the rosette formation between SRBC-IgG and U937 cells was statistically significant(20.3% vs 53.2%,P

OBJECTIVETo investigate the expression of STK15 and P53 proteins in oral precancerous lesions and oral squamous cell carcinoma (OSCC) and elucidate the possible role of P53/STK15 switch activation-independent pathway in oral carcinogenesis.

METHODSFormalin-fixed, paraffin-embedded tissues of 8 cases of normal oral epithelium, 27 cases of dysplasia with different degree epithelium dysplasia and 43 cases of OSCC with different differentiation were investigated for the expression of STK15 and P53 proteins by using immunohistochemistry. The clinical and pathological significance of STK15 over-expression in oral carcinogenesis were statistically analyzed by SPSS 12.0.

RESULTSSTK15 protein was not detectable in normal oral epithelium and significantly altered from mild-dysplasia to OSCC. The percentage of STK15 over-expression were 40.74% (11/27) in dysplasia and 67.44% (29/43) in OSCC (P < 0.05). The percentage of STK15 over-expression in OSCC with positive P53 staining was significantly higher than that in OSCC with negative P53 staining (P < 0.05). STK15 over-expression was significantly associated with regional lymph node involvement (P < 0.05), while no correlation was found for STK15 over-expression and tumor differentiation, as well as TNM stages.

CONCLUSIONSTK15 up-regulation was an early event in oral carcinogenesis. The up-regulation of STK15 protein in OSCC may partly result from p53 mutations, which probably contribute a role in lymph node metastasis of OSCC as well. P53/STK15 switch activation-independent pathway may play some roles in oral carcinogenesis.
