AIM: To observe the efficacy of intravitreal injection with ranibizumab combined with laser photocoagulation for macular edema ( ME ) secondary to macular branch retinal vein occlusion( MBRVO) .
METHODS:A retrospective analysis included 33 patients (33 eyes) with ME secondary to MBRVO were taken. All patients received intravitreal injection of 0. 5mg ranibizumab ( 0. 05ml ) at first visit. The continue PRN treatment and laser photocoagulation were based on the visual acuity changes and optical coherence tomography findings. The changes of best corrected visual acuity ( BCVA) , central macular thickness( CMT) , and amplitude density and latency of P1 wave in mfERG were observed before treatment and 6mo after treatment.
RESULTS: Before the treatment, logMAR was 0. 68±0.35, 6mo after treatment was 0. 34±0. 23, BCVA was improved obviously ( P < 0. 01 ), BCVA in 21 patients ( 63.64%) were improved in two rows among all the patients. CMT before treatment was(487. 30±63. 58) μm, after treatment was(238. 84±52. 66) μm(P<0. 01). The amplitude densities of P1 wave in ring 1, ring 2 and ring 3 after treatment were significantly increased(all P<0. 01), and the latencies were decrease ( all P < 0. 05 ). The conjunctival hemorrhage was observed in 2 eyes after treatment.
CONCLUSION: Intravitreal injection with ranibizumab combined with laser photocoagulation for ME secondary to MBRVO can reduce the CMT and improve visual function.

OBJECTIVETo dicuss the application and therapeutic effect of middle-forearm flap based on perforator of ulnar artery for electrical burn wound on the wrist.

METHODSFrom Oct. 2009 to Oct. 2012, 10 cases of electrical burn wounds on the wrist were treated. A line from radialis medial epicondyle of humerus to the interior radialis pisiform bone was connected as flap axis. At the midpoint of the line, Doppler flow imaging meter was used to detect the emerging point of perforator vessel. The flap was designed and harvested. The flap was transferred reversely, with superficial vein retaining which was anastomosed with vein at recipient sites in 3 cases. The wounds in the donor sites were closed directly in 2 cases, and with skin graft in 8 cases.

RESULTSAll the 10 flaps survived completely. 7 cases without vein anastomosis underwent obvious flap edema during 2-4 days postoperatively, which resovled 1 week later. Sub-flap tissue necrosis and infection happened in 2 cases, which healed after dressing and drainage. Patients were followed up for 3-36 months with satisfactory results.

CONCLUSIONSThe middle-forearm flap based on perforator of ulnar artery has a stable and reliable blood supply. It offers a new choice for the electric burn wound on the wrist, especially at the ulnar side.

To discuss the influence of dexamethasion on lL-1β and TNF - α expression in suture - induced rabbit corneal neovascularization ( CNV ) and analyze the potential mechanism.
●METHODS: For 43 healthy rabbits, 40 were randomly selected for establishing CNV model in corneal stroma. The right eyes (group A) were received no medicine and the left eyes ( group B) were injected dexamethasone after successfully establishing the model. The no modeling 3 rabbits were normal control group. The morphologic change of corneal was observed with slit lamp microscope and the areas of CNV was calculated every day, then 8 rabbits were randomly chosen for sacrificing at 1, 4, 7, 14, 21d respectively. The pathological characteristics of CNV were observed after HE staining, and lL - 1β and TNF - α expression was detected by immunohistochemistry.
●RESULTS: CNV was grown at the 4d after suture, and the 7-14d was vigorous growth period. inflammatory cell infiltration appeared after HE staining, and CNV was located at the superficial stroma of cornea. lmmunohistochemistry results showed that lL - 1β and TNF - α expression was gradually increased with prolonged suture time. Compared with corneal stitch group, the rabbits cured by dexamethasone were found with less inflammatory cells infiltrating and neovescularization, moreover, the expression of lL - 1βand TNF-α decreased. There were statistical significance between the two groups (P<0. 05).
● CONCLUSlON: Dexamethasone can inhibit the CNV growth by controlling the inflammation of corneal and restraining lL-1β and TNF-α expression.

Myeloid neoplasms with eosinophilia and abnormalities of PDGFRB gene are a new kind of myeloid disorders in the revised 2008 WHO classification. Out of detected 2000 cases of myeloid cell abnormalities in our hospital, 12 cases of myeloid neoplasms with eosinophilia and abnormalities of PDGFRB were found. This study was purposed to summarize and analyze the clinical and laboratorial characteristics of the 12 cases with PDGFRB gene abnormalities. The results indicated that among 12 cases of myeloid neoplasms with PDGFRB abnormalities, 5 cases with TEL/PDGFRB fusion gene, 2 cases with HEPI/PDGFRB, 1 case with PDGFRB mutation, 1 case with RABAPTIN-5/PDGFRB, 1 case with GIT2/PDGFRB, 1 case with TP53/PDGFRB, 1 case with WDR43/PDGFRB fusion gene were detected, showing the polymorphism of PDGFRB gene abnormalities. Among this kind of myeloid neoplasm patients, almost all patients manifested monocytosis and eosinophilia in different degree, the thrombocytosis mainly was observed in atypical myeloid neoplasms, acute leukemia, chromic myelo-monocytic leukemia patients. The treatment with imatinib mesylate for this kind of patients was effective in some cases. It is concluded that the myeloid neoplasms with PDGFRB gene abnormalities are a kind of heterogenetic myeloid neoplasms, their gene abnormal types and clinical manifestations show polymorphism too. The monocytosis and eosinophilia appear in this kind myeloid neoplasms which may be treated with tyrosine kinase inhibitors such as imatinib mesylate.

Objective To analyze the outcomes of the surgery repair for total anomalous pulmonary venous connection(TAPVC),and to investigate the risk factors which influence the mortality of the operation.Methods Comparative analysis was performed in the children with TAPVC who were treated operatively from Sep.2001 to Sep.2011 in the Third Affiliated Hospital of Zhengzhou University,Henan Diagnosis & Treatment Center of Congenital Heart Disease.The children included 37 male and 20 female,aged from 15 days to 6.5 years[(4.27 ± 8.63) months],with body weight 4.0-21.0 (6.33 ± 2.70) kg,and the clinical records in hospital including echocardiogram operation records were collected.The clinical data including the age on operation,body weight,diagnosis,anatomic type of TAPVC,the emergency event before operation,cardiopulmonary bypass time,aortic crossclamping time,were analyzed by chisquared test and Logistic multivariable regression analysis.The risk factors influencing the early mortality of TAPVC were analyzed.Results Fifty-seven children underwent the operation,and 7 (12.2％)cases died during the operation.The univariate analysis on outcomes indicated that the risk factors influencing the mortality of the operation included body weight(P =0.035),anatomic type of TAPVC (P =0.037),the emergency event before operation (P =0.021),and aortic crossclamping time(P =0.046).The Logistic multivariable regression analysis indicated that the emergency events before operation was the independent risk factor for the mortality of TAPVC(P =0.003).Conclusion TAPVC children with preoperative emergency events have higher postoperative mortality.

OBJECTIVETo investigate the changes in the plasma levels of endotoxin in severe burn patients during administration of antibiotics.

METHODSFifty severe burn patients with burn area larger than 30% TBSA were enrolled in the study, and they were respectively treated with Netilmicin (A group), Cefoperazone (B group), Ceftazidime (C group) and Imipenem/Cilastatin (D group). Venous blood samples were harvested for determination of endotoxins levels before treatment and 1, 2, 3, 5, 7 post-treatment day (PTD).

RESULTSThe plasma levels of endotoxin were elevated in different degrees in A, B and C groups. The plasma levels of endotoxin in B group were higher on 1, 2 PTD than on 3, 5, 7 PTD, and they were also higher than that in D group (P < 0.05). The plasma levels of endotoxin in C group reached the peak on 5 PTD [(0.398 +/- 0.172) EU/mL], which were higher than that before treatment [(0.251 +/- 0.142) EU/mL, P < 0.05] and other groups (P < 0.05). The plasma levels of endotoxin in D group were lower on 1, 2 PTD than that before treatment (P < 0.05).

CONCLUSIONDifferent amounts of endotoxins can be released after treatment with antibiotics in severe burn patients. Attention should be paid to the effect of antibiotics on the levels of endotoxin in practice.
