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.

OBJECTIVETo establish an HPLC fingerprint to evaluate the quality of Polygalae Radix, root xylem, and those collected in different growth ages or harvest time.
METHODSeparation was performed at 30 °C on a Kromasil C18 column (4.6 mm x 250 mm, 5 μm); the mobile phases was acetonitrile and 0.05% H3PO4 water in the gradient elution; the flow rate was set at 1.0 mL · min(-1) and the detection wavelength at 314 nm; the quality discriminant analyses were accomplished by means of similarity analysis, cluster analysis, principal component analysis and neural network model.
RESULTIn 26 batches of Polygalae Radix, 24 batches fingerprint similarities were above 0.8. In 5 different growth or harvest time batches, 4 batches were above 0.8; in 8 batches root xylem samples, the similarities were all above 0.875. The similarity analysis was in accord with the quality discriminant analysis of cluster analysis, principal component analysis and neural network model.
CONCLUSIONFingerprint combined with chemical pattern recognition technique can effectively evaluate the quality of Polygalae Radix. The active substance species are all similar in cultivated, wild, different growth or harvest time Polygalae Radix and polygala root xylem, but the chromatography peak areas are different. The effective material contents are similar between wild and cultivated Polygalae Radix, but each chromatographic peak area of the root xylem is much smaller than that of Polygalae Radix. The chemical substance accumulation mainly depends on harvest month, but little growth time in Polygalae Radix.

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.

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.

Background Eyes with filamentary keratitis present with serious clinical symptoms.This disease is easy to relapse and the treatment is tricky.At present,its pathogenesis is still unclear,and few works were done on filamentous composition.Objective This study was to analyze the composition of corneal filament by imageological and histopathological method,and discuss the formation mechanism of filamentary keratitis.Methods Eighty-eight eyes of 82 cases who suffered from filamentary keratitis were collected in Shandong Eye Hospital between January 2008 and January 2011.The etiologies of the patients were classified and the clinical data were recorded.Firstly,the corneal filiform strip was detected by laser scanning confocal microscopy (LSCM),and the corneal structure was examined by high-definition optical coherence tomography (HD-OCT).Then the composition of filamentary strip was analyzed by Giemsa and Masson trichrome staining of stretched preparation of filiform strip.Results Etiological study showed that filamentary keratitis occurred after penetrating keratoplasty in 40 eyes,after cataract surgery and photorefractive keratectomy (PRK) in 18 eyes,dry eye and neural dystrophic corneal disease in 14 eyes,acute conjunctivitis in 10 eyes.HD-OCT revealed that filament lesion developed to Bowman layer.Filament was composed of epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement under the LSCM,and epithelial cells,inflammatory cells and fibrous tissue were seen in the strip core.Giemsa staining exhibited that filament contained corneal epithelial cells,inflammatory cells,mucus and dark blued strip core with helical arrangement.Masson trichrome discovered that the strip core was red fibrous tissue surrounding by blue mucus.Conclusions Epithelial cells,inflammatory cells,mucus and the high reflective strip core with spiral arrangement are the main elements of filament in filamentary keratitis.The lesion can reach Bowman layer.The results contribute to reveal the formation mechanism of corneal filament and assist treatment.
