AIM: To observe the clinical efficacy and safety of vincamine sustained release capsules on non- arteritic anterior ischemic optic neuropathy ( NAION) . · METHODS: Patients who were diagnosed with monocular onset NAION in acute stage from January to September 2015 were divided into two groups. Routine treatment such as steroid pulse therapy and neurotrophic treatment were given to all the patients. Vincamine was added to the treatment group patients with 30mg twice a day for 3mo. The best corrected visual acuity ( BCVA), mean deviation ( MD) of visual field, retinal nerve fiber layer ( RNFL ) , ganglion cell complex ( GCC ) , pattern visual evoked potential ( PVEP ) and OCT results were analyzed before and after the treatment. ·RESULTS:Totally 42 eyes of 42 patients were enrolled in our study. There were 27 patients in the treatment group, aged from 33 to 79 years old, the average value was 55. 55± 11. 83 years old. The control group has 15 patients, aged from 40 to 70 years old, the average value was 55. 71 ± 10. 06 years old. There were no statistical differences between the two groups in the baseline. After 3mo of the treatment, MD value of the two groups were lower compared with the baseline, the difference was statistically significant in the treatment and control group respectively (t= 2. 342, 2. 692; P = 0. 027, 0. 041). The difference of PVEP amplitude and potential of the two groups before and after the treatment were not statistically significant. The thickness of retinal nerve fiber layer and the ganglion cell complex were all lower than the baseline, and the difference was statistically significant (P<0. 001). The treatment of the two groups were both effective, the treatment group has better treatment effect than the control group. Adverse events related to the treatment of vincamine had not been found. ·CONCLUSION:Vincamine is helpful in the treatment of non-arteritic anterior ischemic optic neuropathy.

Background Light-induced retinal damage models vary as many influence factors,herein the modeling method is difficult to copy.It is necessary to establish the grading standardization of retinal damage after retinal light exposure.Objective This study was to improve the modeling method and establish a grading standardization for light-induced retinal damage in rat.Methods Twenty-four SPF 8-10 week-old male SD rats were randomly divided into 4 groups and 6 eyes for each group.The rats were exposed to light intense of 5000 lx for 1,2,3 hours respectively in 3 groups,and other 6 rats served as the normal group.Full-field light exposure experiment was performed for each individual rat separately,and an annular illumination box was used tO ensure the experimental rat moving in a single direction and exposing the right eye in 5000 lx light surrounding during experimental duration.Ganzfeid electroretinogram(ERG)was recorded from the experimental rats at the fifth day after light exposure,and the animals were then sacrificed for histopathology observation to evaluate the retinal thickness change.All procedures which involved animals adhered to the ARVO Statement for the Use of Animals in Ophthalmic and Vision Research.Results After exposing to intensity light for 1,2,3 hours,the b-wave amplitudes of rod response,maximal mixed response,oscillatory potential in scotopic ERG as well as cone response,20 Hz flicker response of photopic ERG were significant declined as lapse of light exposure time(F=71.690,P=0.000；F=56.250,P=0.000；F=23.610,P=0.000：F=27.130,P=0.000；F=27.030,P=0.000)and lowed by 26.2％,52.5％,70.7％,24.4％,39.3％,58.1％respectively at the end of experiment.Meanwhile,the b-wave latencies of rod response,maximal mixed response in scotopic ERG as well as cone response of photopic ERG were evidently different among different groups (F=1.370,P=0.282；F：0.800,P=0.508；F=11.840,P=0.000；F=2.080,P=0.136).Light induced retinal damage located mainly at the temporal retina area.After intensity light exposure for 1,2,3 hours,the thickness of outer nuclear layer at the superior temporal retina attenuated by 11.3％,25.6％and 72.5％,respectively(P<0.05).A significant difference was seen in mean thickness of outer nuclear layer at superior temporal retina among different groups(F=410.27,P=0.000). Conclusion A standardized grading method for light-induced retinal damage is recommended.The continuous illumination in a intensity of 5000 Ix for 1,2,3 hours can induce the mild,moderate or severe retinal damage respectively at temporal retina.

Objective To investigate serum DJ-1 expression and its significance in ovarian cancer. Methods The expression levels of DJ-1 protein were detected by double antibody sandwich method in 52 cases of ovarian tumors (9 cases of benign ovarian tumors, 5 cases of borderline ovarian tumors and 38 cases of ovarian cancer,ovarian tumor group and 20 non-ovarian tumors (control group).

OBJECTIVETo investigate clinicopathologic features of solitary plasmacytoma of bone (SPB) and the role of immuno-phenotype and immunoglobulin gene rearrangement detection in the diagnosis and differential diagnosis of SPB.

METHODSA total of 21 cases of SPB were selected during a period from 1990 to 2008. A retrospective clinicopathologic study and immunohistochemistry (EnVision or EliVision methods) of 17 antigens were performed. In addition, universal IgH (FR3A/LJH/VLJH) primers and BIOMED-2 PCR multiplex tubes were used for IgK and IgL rearrangement analysis.

RESULTSThe age of patients ranged from 36 to 72 years with a media of 50 years. Axial skeleton was the most common site of involvement, accounting for 66.7% of the cases (14 of 21), followed by the extremities of 33.3% (7 cases). Low serum level of M-components was found in 5 cases, including two of IgG type (21.4 g/L) and three of IgA type. Clinical manifestations were closely related to the anatomic sites involved, such as pain due to bone destruction, symptoms and signs caused by compression of spinal cord or nerve root, and pathological fracture. All cases presented as a solitary osteolytic lesion. According to the histological grading criteria, grade I tumor was seen in 12 of 21 cases (57.1%). The remaining were grade II (5 cases, 23.8%) and grade III (4 cases, 19.0%). Immunohistochemically, the neoplastic cells expressed two or more plasma cell antigens, including CD138, CD38 and PC, but no CD19 and CD20. CD79a expression detected in 23.8%(5/21) of the cases. Expression of CD56, CD27 and CD44v6 were 57.1% (12/21), 15.0% (3/20) and 23.8% (5/21), respectively. Follow-up data were available in 12 of the 21 patients (57.1%). Five patients were alive and 7 died. Three patients developed multiple myeloma (MM) and died of the tumor.

CONCLUSIONSSPB is a rare tumor with bone pain as the most common presenting symptom due to bone destruction. The diagnosis of EMP can only be established after exclusion of an extramedullay invasion by MM. Immunophenotype and IgH gene rearrangement analysis play important roles in the diagnosis of SPB.

OBJECTIVETo study the relationship of Helicobacter pylori (H. pylori) infection with the development and relapse of Henoch-Schonlein purpura (HSP) with gastrointestinal involvement in children.

METHODSThirty-six HSP children with gastrointestinal manifestations and 16 of 32 HSP children without gastrointestinal involvement underwent gastroscopy and rapid urease test for H. pylori detection. Thirty healthy children served as the control group. All of the patients received 14C urea breath test and serum H. pylori antibody detections. H. pylori infection was definited when two of detection approaches demonstrated positive.

RESULTSTwenty-one of 36 HSP patients with gastrointestinal manifestations were confirmed with H. pylori infection (58.3%). Of them, the relapsed patients had an H. pylori positive rate of 81.3% (13/16), which was significantly higher than that of the newly diagnosed patients (45.0%, 9/20) (chi(2)=4.49, P < 0.05). Nine of 32 HSP patients without gastrointestinal manifestations were confirmed with H. pylori infection (28.1%); 2 of 30 healthy children showed H. pylori positive (6.7%, 2/30). There was a significant difference in the H. pylori positive rate among the three groups (chi(2)=14.7, P < 0.01).

CONCLUSIONSH.pylori infection may be associated with the development and relapse of HSP with gastrointestinal involvement in children.

OBJECTIVETo investigate the expressions of matrix metalloprotein-2 (MMP-2) and tissue inhibitor of metallopeptidase inhibitor-1 (TIMP-1) in the renal allografts of patients with chronic active antibody-mediated rejection (ABMR), and explore their role in the pathogenesis of ABMR.

METHODSImmunohistochemistry and computer-assisted image analysis were used to detect the expression of MMP-2 and TIMP-1 in the renal allografts of 46 patients with interstitial fibrosis and tubular atrophy (IF/TA), with 15 normal renal tissue specimens as the control. The association of MMP-2 and TIMP-1 with the pathological grade of IF/TA in ABMR was analyzed.

RESULTSThe expressions of MMP-2 and TIMP-1 significantly increased in the renal tissues of the patients as compared with the normal renal tissues (P<0.05). MMP-2 expression tended to decrease, while TIMP-1 and serum creatinine increased with the pathological grades of IF/TA (P<0.05). In IF/TA group, the expression of TIMP-1 was positively correlated to serum creatinine level (r=0.718, P=0.00<0.05).

CONCLUSIONAbnormal expressions of MMP-2 and TIMP-1 can promote the development of renal fibrosis in chronic ABMR.
