AIM: To evaluate the ability of spectral domain optic coherence tomography ( SD-OCT ) parameters to detect progressive structural damage in primary open angle glaucoma ( POAG) by contrasting with visual field. ·METHODS: Retrospectively we evaluated 48 subjects (48 eyes ) of POAG, followed up 14 to 62mo. The parameters of SD-OCT and visual field were obtained. The correlation between the change of visual field measurements and OCT measurements were analyzed. Visual field progression was defined as reproducible drop of at least 2dB of mean deviation (MD) from the baseline visit. ROC curve was made to evaluated the ability of OCT parameters in detect progression of POAG. ·RESULTS: The 25 eyes were classified in progression group and 23 eyes were in non-progression group. No significant correlation was seen between OCT parameters and visual field in non-progression group. In progression group, OCT parameters which were significantly correlated with MD reduce were rim volume ( r=-0. 5997, P=0. 0007), C/D vertical ratio (r=-0. 6309, P=0. 0003), RNFL(r= 0. 4201, P= 0. 0260), and GCC(r= 0. 7080,P<0. 01). ROC curves showed the GCC reflected the reduce of MD accurately (P=0. 013). ·CONCLUSION: Part parameters of SD-OCT can reflect the progression of POAG accurately and provided a new method to detect the damage of visual function of POAG.

OBJECTIVETo explore the clinical characteristics of Cornelia de Lange Syndrome (CdLS) and to review the latest clinical research reports.
METHODClinical and laboratory data of one case of neonatal CdLS are reported, and literature on 17 cases of CdLS in China and the international reports of the clinical and molecular biological research on this disease were reviewed.
RESULT(1) The patient was an infant with intrauterine growth retardation and born as a term small for gestational age infant with specific facial features, bone abnormality of extremities, and patent ductus arteriosus (PDA). She also had severe feeding difficulty and slow weight gain. She was followed up till 4 months of age and showed severe developmental retardation. (2) The total number of past reported case of CdLS in China was 17 with a male to female ratio of 6:12. The average age of diagnosis was 17 months. The following specific facial features could be observed: synophrys, long and curved eyelashes, hirsutism, microcephalus, low hairline, broad depressed nasal bridge, long prominent philtrum, and high palate. Most of the patients were complicated with mental retardation, recurrent vomiting or feeding difficulty, abnormal muscle tone, cutis marmorata, hypophalangism, and genitalia anomaly. Clinical manifestations of Chinese patients were similar to those of the overseas reports. The karyotype of 15 cases was investigated and was normal. The etiology of CdLS is unknown. There is no specific treatment. The commonest causes of death are lung diseases caused by gastroesophageal reflex/aspirate related pneumonia.
CONCLUSIONTypical clinical manifestations of CdLS are specific facial features (mainly synophrys, long and curved eyelashes, long prominent philtrum), complications of multi-system malformations (mainly growth and developmental retardation, esophagogastric reflex, hypophalangism), related gene mutations occurred in NIPBL, SMC1A, and SMC3 gene.

AIMTo observe the injured effect of homocysteine (HCY) on cardiomyocytes and investigate its signal transduction mechanism as well as the key regulatory link.
METHODSCardiomyocytes were isolated from neonatal Wistar rats. After incubation with HCY, the survival rate of cardiomyocytes was determined by trypan blue stained assay, while the apoptosis rate was measured by TUNEL and FCM. Western blot and EMSA were used to tested ERK2 protein phosphorylation and NF-kappaB active expression in cardiomyocytes, respectively.
RESULTSThe survival rate of cardiomyocytes treated with HCY was reduced significantly in dose- and time- dependent manner. It was found that 10(-3) mol/L HCY could increase the apoptosis rate of cardiomyocytes to the peak (7.65%) at 4 h stress. Several HCY levels revealed the strong inhibitory effect on ERK2 protein phosphorylation, especially, 10(-3) mol/L HCY decreased the level of active ERK2 expression to 3.04% of control at 4 h (P < 0.01). NF-kappaB activation was also inhibited significantly by several HCY level for different time in cardiomyocytes.
CONCLUSIONHCY plays an important role in injury of cardiomyocytes and apoptosis is a form of HCY-induced injury to cardiomyocytes. HCY can block ERK2 protein phosphorylation and NF-kappaB activation, which contribute to the injury of cardiomyocytes.

OBJECTIVETo investigate the vasorelaxation effect of emodin and its relationship with NO-cGMP signal pathway.
METHODSChanges of tension of rat thoracic aortic rings were measured by MedLab biologic signal collection system, and the activity of total nitric oxide synthase (tNOS), constitutive NOS (cNOS) and inducible NOS (iNOS) in endothelium after being treated with emodin was determined with nitric acid reductase method.
RESULTSEmodin relaxed the phenylephrine and potasium chlorate induced contraction of aortic rings, either with or without intact endothelium, in a concentration-dependent manner. Pretreatment of no-specific potassium channel blocker strontium chloride (CsCL) could attenuate the vasorelaxation effect of emodin on aortic rings without intact endothelium, but it could not inhibit vasorelaxation of emodin on aortic rings with intact endothelium. This vasorelaxation action of emodin (40 micromol/L) could be partial blocked by NOS inhibitor L-NAME and guanylate cyclase inhibitor ODQ, with the vasorelaxation range dropped to 64.76 +/- 13.73% and 6.28 +/- 4.79% respectively. Moreover, emodin (40 micromol/L) increased iNOS activity significantly.
CONCLUSIONThe concentration-dependent vasorelaxation effect of emodin might act by activating the NO-cGMP pathway in vascular endothelium.
