Objective To explore the clinical manifestations of toxic epidermal necrolysis(TEN) and its rare pulmonary complications.Methods Clinical symptoms,treatment and prognosis of 1 child with TEN caused by carbamazepine were analyzed.Radiological images were reviewed to evaluate the manifestations and the outcome of chronic pulmonary complications associated with TEN.Results The patient had high fever shortly after a dosage increment of carbamazepine.A confluent erythematous exanthema developed rapidly into painful blistering with skin erosion,denudation and involvement of conjunctive and oropharyngeal mucosa.The diagnosis of TEN was made.The mucocutaneous damage was gradually recovered with steroid plus intravenous immunoglobulin for 3 weeks.However,the patient presented with respiratory failure in the recovery phase of TEN.The computer tomography revealed pulmonary bullae and pneumothorax in the right lung.Lung parenchyma was squeezed and pulmonary bullae ruptured with pneumothorax and atelectasis,which were absorbed gradually through thoracic drainages.The patient′s lung function and pulmonary bullae were partly improved during a 7-month follow-up.Conclusions TEN is a severe form of blistering skin di-sease which is characterized by an extensive loss of epidermis and mucous membrane.Chronic pulmonary complications may occur in recovery phase of TEN.Pulmonary bullae,which might be caused by mucous damage and respiratory obstruction,is a rare complication of TEN.

The study reports the detection of neuroprotective effect of 10 kinds of coumarin derivatives and explores their possible mechanism. MTT method was used to screen the neuroprotective effect of 10 coumarin derivatives on neurotoxic agents (Aβ25-35 and rotenone) or OGD (oxygen-glucose deprivation). A compound with better protective effect was obtained. Then the effect of this compound on neurotoxic agents on PC12 was detected by the morphological observation. Furthermore, the effect of compound 3 on microglia with lipopolysaccharide (LPS) induced inflammation was detected. And the inflammatory factor was tested. Finally, direct free radical scavenging ability was detected. Compound 3 was found to be the best compound through three neurons toxic models. Not only compound 3 ameliorated cell viability reduced by three neurons toxic models, but also significantly inhibited the production of inflammatory factor (TNF-α and IL-1β). And its free radical scavenging ability is very good, especially the effect on superoxide anion, which is comparable with vitamin C. The significant scavenging effect of compound 3 on superoxide anion might be the mechanism of the neuroprotection. Compound 3 as a potential neural cell protective agent merits further investigation.

AIM: To observe the effect of Ahmed glaucoma valve implantation intravitreal bevacizumab in the treatment of neovascular glaucoma ( NVG) .
METHODS:Twenty-two cases (22 eyes) who presented with NVG were first treated with intravitreal bevacizumab 0. 1mL ( 2. 5mg ), then with Ahmed glaucoma valve implantation after regression of iris neovessels. Cases were followed - up for 6 - 36 ( mean 24 ) mo with observation on visual acuity, IOP control, regression of iris neovessels, and complications during or after surgery.
RESULTS: Iris neovessels was regressed in different degree after injection within 1wk in 22 eyes. At final follow-up, the IOP of 18 eyes were all less than 21mmHg without any drugs and of 3 eyes with 1-3 kinds of anti-glaucoma drugs after combined Ahmed glaucoma valve implantation. The IOP of one eye was controlled after cryotherapy. The mean IOP dropped from 45. 36 ±8.13mmHg preoperatively to 15. 59 ± 3. 21mmHg postoperatively. IOP reduction was statistically significance between preoperative and postoperative ( P<0. 05) at final follow-up. Visual acuity was improved in 9 eyes (41%) and was no changed in 13 eyes. No serious complications were observed during or after intravitreous bevacizumab injection and Ahmed glaucoma valve implantation.
CONCLUSION: Ahmed glaucoma valve implantation and intravitreal bevacizumab in the treatment of NVG is useful and safe. It improves the success rate of surgery and preserves visual function, furthermore its complications are less.
