AIM:To report the safty and efficiency of intravitreal injection of bevacizumab (Avastin) in patients with macular edema (ME) due to branch retinal vein occlusion (BRVO).METHODS: A consecutive series of patients with ME due to BRVO who were treated with intravitreal bevacizumab injection (2.5g/0.1L) were retrospectively studied. Patients underwent complete ophthalmoscopic examination, including Snellen visual acuity testing, optical coherence tomography (OCT) imaging, and/or flurescence angiographic testing at baseline and follow-up visits.RESULTS: There were 32 eyes of 32 consecutive patients who received at least one intravitreal bevacizumab injections (range from 1 to 3). The mean length of follow-up was 4.7 (range from 3 to 8) months. The mean visual acuity improved from 20/200- at baseline to 20/100- at 1 month and 20/100+ at 3 months and last follow-up (P＜0.01). The mean central 1mm macular thickness was 483μm at baseline and decreased to 275, 314,and 301μm at 1 month,3 months, and last follow-up (P＜0.01)respectively.No adverse side effects were observed following injections in any eyes.CONCLUSION: Intravitreal bevacizumab (Avastin) showed a marked decrease in ME secondary to BRVO, improvement in visual acuity and lack of adverse side effects.

Objective To compare the sensitivity of HE,immunohistochemistry (IHC) and RT-PCR in detection of breast cancer metastases in axillary lymph nodes.Methods Twenty female patients with newly diagnosed and clinically node-negative breast cancers underwent modified radical mastectomy, including a complete axillary lymph node dissection. The ages of the patients ranged from 31 years to 65 years, and the diagnosis of breast cancer was approved by pathological finding. Two hundred and thirty-nine axillary lymph nodes were found in these 20 patients. Metastases in axillary lymph nodes were explored by HE, cytokeratin 19 IHC and RT-PCR for cytokeratin 19 respectively. Results Seven(2.9%) lymph nodes were found to have metastatic cancers by HE in 3 patients,all nodes were found in level Ⅰ. Metastatic cancers were found in 13 (5.4%) nodes by IHC in 7 patients,11 nodes in level Ⅰ and 2 nodes in level Ⅱ; and 52(21.8%) nodes were found to contain tumor cells by RT-PCR in 14 patients,30 nodes in level Ⅰ and 22 nodes in level Ⅱ. All of 7 histologically(HE) positive nodes were found to contain tumor cells by IHC and RT-PCR. Among 232 histologically(HE) negative nodes,6(2.6%) nodes were found to contain tumor cells by IHC,and 45(19.4%) nodes were found to contain tumor cells by RT-PCR, all 6 IHC positive nodes showed the expected 460-base pair products on gel electrophoresis ( P

AIM: To investigate the safety and effect of EX-PRESS glaucoma drainage device on open-angle glaucoma.
METHODS: A retrospective review of 40 patients ( 47 eyes ) whose eyes were diagnosed as open angle glaucoma through the best - corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , gonioscope, examination of the ocular fundus, and visual fields et al. Fourty patients 6-73y old ( mean 39. 90±16. 50y old) with the BCVA from 0. 01 to 0. 6 and the IOP from 18mmHg to 65mmHg were treated with EX-PRESS glaucoma drainage device after achieving not well IOP over three drugs. Follow - up of these patients 1d, 3d and 1wk after treatment, IOP, slit lamp examination were retrospectively observed. The changes of the BCVA, IOP were used to evaluate the safety and effect before and after treatmeat.
RESULTS: The mean BCVA was 0. 26 ± 0. 29 pre -operatively, while it was 0. 24±0. 22 after treatment one week. The mean BCVA decreased slightly, but there was no statistic difference between pre-treatment and post-treatment (t=1. 56,P=0. 13). The mean IOP was (36. 62 ±14.01)mmHg pre-operatively, (10.04±5.77)mmHg after treatment one day , ( 9. 59±4. 93 ) mmHg after treatment three days, (9. 47±3. 06)mmHg after treatment one week. The IOP was decreased significantly in post-treatment after one day, three days, one week compared with pre-treatment (F=157. 20, P<0. 05). Except for 5 eyes of the IOP below 5mmHg, there was no ocular or systemic adverse events observed in all patients.
CONCLUSION:EX-PRESS glaucoma drainage device is an effective and safe treatment for the patients with open-angle glaucoma. The risk and complication are low intraoperatively and postoperatively.

Objective To investigate methods for prenatal molecular diagnosis of fetuses at high risk for X-linked adrenoleukodystrophy(X-ALD).Methods The amniotic fluid was obtained and genomic DNA was isolated from amniotic fluid cells.Maternal contamination was evaluated by paternity test.PCRRFLP,sequencing and denaturing high performance liquid chromatography(DHPLC)were used to detect the ABCD1 gene of fetal genome.Results In the pedigree 1,the PCR product(799 bp)of the fetus 1 and her father(normal control)could be digested with BcnI. No P560L mutation,which was present in the index patient,was detected in the ABCD1 gene from the genomic DNA of the fetus 1 using direct sequencing.In the pedigree 2,the PCR product(232 bp)of the fetus 2 and her father could not be digested with MaeI and no Q177X mutation,which was present in the propositus,was detected in the ABCD1 gene from the genomic DNA of the fetus 2 using direct sequencing.In the pedigree 3,the PCR product(271 bp)was digested with AciI.the pattern of the fetus 3 and the propositus being the same,and the R617C mutation was found in the ABCD1 gene from the genomic DNA of the fetus 3 using direct sequencing.In the pedigree 4,the PCR product(269 bp)was analyzed with the DHPLC,and the pattern of elution peaks of the fetus 4 and her father was similar,but different from that of the propositus.No K276E mutation was detectable in the ABCD1 gene from the genomic DNA of the fetus 4 by using direct sequencing.Judging from the sex of the fetuses,fetuses 1 and 2 were normal homozygotes,fetus 3 was an ALD hemizygote,and fetus 4 was a normal hemizygote.Conclusion A new protocol for X-ALD prenatal molecular diagnosis is proposed,which would ensure the accuracy of prenatal diagnosis.

Aim To investigate the up-regulation of miR-22 through Wnt pathway inhibits the proliferation,migration and invasion in human gastric MGC803 cells induced by diallyl disulfide(DADS).Methods The effects of proliferation,migration,and invasion of gastric cancer cells were evaluated by MTT,wound-healing and invasion assays.Online prediction software was applied to search the target gene of miR-22.Luciferase report gene assay was used to assess the target genes Wnt-1 of miR-22.The expressions of Wnt-1,β-catenin and TCF-4 were tested by qRT-PCR and Western blot,respectively.Results MTT showed that DADS and miR-22 notably decreased the proliferation compared with control group(P<0.05).Wound-healing assay showed that DADS and miR-22 could significantly inhibit the migration of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Invasion assay showed that DADS and miR-22 could markedly inhibit the invasion of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Online prediction software to search the target gene exhibited that Wnt-1 may be a target gene of miR-22. Luciferase report gene assay disclosed that Wnt-1 was identified as a direct target of miR-22. Qrt-PCR showed that the expression of Wnt-1 Mrna was respectively down-regulated by DADS and miR-22 compared withcontrol group, especially in miR-22+DADS(P<0.05). Western blot exhibited that DADS and miR-22 obviously suppressed the expressions of Wnt-1, β-catenin and TCF-4 proteins, especially in miR-22+DADS(P<0.05).Conclusion Up-regulation of miR-22 through Wnt pathway can remarkably suppress the proliferation, migration and invasion in MGC803 cells by DADS.

Objective To explore the imaging characteristics of intrathoracic extramedullary hematopoiesis(EMH).Methods Clinical and imaging findings of 6 cases with EMH were retrospectively analyzed,and the imaging characteristics,diagnosis and differential diagnosis were discussed.Results Among 6 the cases of EMH,3 lesions were located in mediastinum,and the other 3 lesions in mediastinum and adjacent chest wall.Five cases appeared as globular shadows which protruded toward the lung fields on X-ray films,on plain CT scan,all the 6 lesions appeared of smooth margin and homogeneous soft-tissue density,and the CT values ranged from 38 to 45 HU.Two lesions showed slight homogeneous enhancement on postcontrast CT scan using the common CT scanner,and the CT values ranged from 61 to 65 HU.Four lesions showed significant homogeneous enhancement on postcontrast CT images using the 16-slices CT,and the CT values ranged from 72 to 83 HU.On MRI images,4 lesions showed the same signal intensity as compared to adjacent muscles on T_1WI and T_2WI,and there was slight enhancement of the lesions after intravenous contrast administration.Conclusion EMH has specific imaging findings,and accurate diagnosis can be made by combining X-ray,CT and MR imaging findings with clinical history.

OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.
