AIM: To observe the changes in subfoveal choroidal thickness ( SFCT ) after intravitreal injections of ranibizumab ( IVR ) for macular edema secondary to retinal vein occlusion ( RVO) .
METHODS:Thirty-six eyes of 36 patients with macular edema secondary to RVO) were treated with 0. 5mg IVR monthly for 3mo and received additional IVR as needed over the following 1a period. SFCT of the all eyes ( the affected eyes with RVO and unaffected fellow eyes ) was measured by enhanced depth imaging optical coherence tomography images before and after the IVR.
RESULTS: The mean SFCT of the affected eyes with RVO decreased from 246. 7±115. 0μm at baseline to 220. 5±102.0μm at 1mo (P<0.05), 198.3± 114.0μm at 6mo (P<0.01), 212. 6± 96. 0μm at 12mo (P<0. 01). Whereas the fellow eyes changed from 229. 4±108. 0μm at baseline to 226. 3±107. 0μm at 1mo (P>0. 05), 228. 6±127. 0μm at 6mo (P>0.05), 223.6±101.0μm at 12mo(P>0.05). There were statistically significant difference between affected eyes with RVO and unaffected fellow eyes.
CONCLUSION: The SFCT is decreased after IVR for macular edema secondary to RVO. IVR seems to affect the hemorheology of the choroid.

Objective To analyze the ultrasonic features of interrupted inferior vena cava (IVC) and its relationship with related deformities so as to improve the prenatal diagnosis of isomerism.Methods Pregnant women who received prenatal care in Peking University People's Hospital or who were referred to our hospital for suspected malformation of fetus between January 2010 and December 2013 were enrolled in this study.Fetal echocardiography and abdominal transverse section were performed routinely.Spatio-temporal image correlation technology was used to further clarify interrupted IVC if azygos vein was broadened or IVC disappeared in the fetal abdominal transverse sections.Based on the presence of cardiac structural abnormalities,interrupted IVC was divided into isolated IVC interruption and complex IVC interruption.Neonatal echocardiography was performed in women with continued pregnancies.In women with terminated pregnancy,fetus was autopsied after induced labor.Results In total,12 cases of interrupted IVC were diagnosed,including 5 cases of isolated IVC interruption with full-term delivery and 7 cases of complex IVC interruption.Neonatal echocardiography,abdominal ultrasound were all normal in the 5 cases of isolated IVC interruption except for 3 cases complicated with sistus inversus viscerum.All the 7 cases of complex IVC interruption had induced labor because of some congenital cardiac abnormalities.Autopsy showed that 6 cases had left isomerism,and 1 case had right isomerism.Conclusions Interrupted IVC can be easily identified in prenatal diagnosis due to the typical ultrasonic features.Complication with some congenital cardiac abnormalities often indicates isomerism,especially left isomerism.

OBJECTIVE:To observe clinical efficacy and safety of Mailuoning injection in adjunctive treatment of acute cere-bral infarction. METHODS:A total of 65 patients with acute cerebral infarction selected from neurology department of our hospital were divided into control group(32 cases)and observation group(33 cases)according to random number table. Control group was given conventional treatment. Observation group was additionally given Mailuoning injection 10 mL added into 0.9% sodium chlo-ride injection 250 mL intrnrenously,ivgtt,qd,on the basis of control group. Both group were treated for 15 d. Clinical efficacy as well as serum levels of ox-LDL,BNP and MMP-9,NIHSS score before and after treatment,the occurrence of ADR were com-pared between 2 groups. RESULTS:The response rate of observation group was 90.91%,which was significantly higher than 65.63%,with statistical significance(P<0.05). Before treatment,there was no statistical significance in serum levels of ox-LDL, BNP or MMP-9,NIHSS score between 2 groups (P>0.05). After treatment,serum levels of ox-LDL,BNP and MMP-9,NIHSS score in 2 groups were all decreased significantly,and the observation group was significantly lower than the control group,with statis-tical significance (P<0.05). There was no statistical significance in incidence of ADR between 2 groups (P>0.05). CONCLU-SIONS:Mailuoning injection has significant therapeutic efficacy for acute cerebral infarction,can significantly reduce serum levels of ox-LDL,BNP and MMP-9,promotes neurological function and the recovery of patients with cerebral infarction with good safety.

39℃)developed at the progressive stage of this disease.Physical examination showed variously sized,round or oval,atrophic and variola-like scars along with scattered erythematous patches,papules, necrosis and crusts on the face and extremities.The face was edematous,and there were some edematous and erythematous plaques with a necrotic center on the legs and arms.Histological examination revealed a massive infiltration with atypical CD8~+lymphocytes around the vessels and appendages in dermis.A diagnosis of CD8~+cutaneous T-cell lymphoma(CTCL)was made.Glucocorticoid and immunosuppressants were effective in controlling the condition.Up to the time of the writing,there has not been any definite evidence of systemic involvement.

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.

NMDA-induced excitotoxicity cause severe neuronal damage including apoptosis and necrosis. The present study was aimed to evaluate the proportion of NMDA-induced apoptosis of rat cortical neurons and discover signal transduction mechanism. Caspase inhibitor and lactate dehydrogenase (LDH) assay were used to study the NMDA-induced apoptosis. To explore the involved signal pathways, the primary culture of rat cortical neurons were pretreated by the inhibitors of three MAPK pathways, extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38 MAPK. With 2 h of NMDA treatment, cellular apoptosis was measured by caspase-3 activity, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling (TUNEL) and Annexin V staining. The results showed that: (1) Caspase-dependent apoptosis accounted for 22.49% in NMDA-induced neuronal death; (2) Pretreatment with p38 MAPK inhibitor SB203580 (10 μmol/L) significantly decreased NMDA-mediated caspase-3 activity by 30.43% (P < 0.05). However, ERK inhibitor PD98059 (20 μmol/L) or JNK inhibitor SP600125 (20 μmol/L) did not influence caspase-3 activity; (3) Pretreatment with SB203580 significantly reduced the number of NMDA-induced TUNEL-positive cells by 33.10% (P < 0.05). PD98059 (20 μmol/L) or SP600125 (20 μmol/L) did not show obvious effect; (4) Pretreatment with SB203580 (10 μmol/L) significantly reduced the number of NMDA-induced early apoptotic neurons by 55.56% (P < 0.05). Also, SP600125 (20 μmol/L) significantly decreased the amount of late apoptotic/dead cells by 67.59% (P < 0.05). There was no effect of PD98059 (20 μmol/L). These results indicate that: (1) NMDA induces neuronal apoptosis besides necrosis; (2) p38 MAPK, but not JNK and ERK, is involved in NMDA-induced neuronal apoptosis, and inhibition of the apoptotic signaling pathway contributes to neuroprotection; (3) JNK activation might contribute to NMDA-induced neuronal necrosis rather than apoptosis.
