BACKGROUND: The evaluation of stereoacuity can provide an unambiguous assessment of haplopia. It is valuable in assessing the diagnosticaccuracy and the therapeutic effect in strabismus, amblyopia and ametropia. OBJECTIVE: This investigation was designed to evaluate the stereopticdevelopment and the occurrence rate of strabismus in 3-6 years old children, and so that to provide objective data for prevention and treatment of strabismus and steropsis. DESIGN: It was a randomized sampling investigation. SETTING: Department of Ophthalmology,Haikou People's Hospital. PARTICIPANTS:Totally 8326 children in 25 urban and suburban kindergartens, with an age of 3-6 years old, were selected randomly in Haikou city from June 2000 to April 2002. METHODS: 8 326 3-6 years old children in Haikou city underwent vision examinations on hyperopia, eye position and the myopia. Those having eyesight lower than 1.0D or abnormal eye position received atropine drops to dilate the pupil of the eye for optometry. ① 4-6 years old children were examined using standard visual chart and logMAR chart (logarithm of the minimum angle of resolution chart), 3 years old children were examined using hroken wheel acuity cards or symbols chart. The results of the exminations were conversed and recorded in form of decimal fraction uniformly. ②The corneal reflection and the cover test procedure were used for the position of gaze. ③ Stereoacuity were examined using the stereoptic visual testing cards (made by the Institute of Biophysics, Chinese Academy of Sciences). Stereoacuity were defined as normal when the test value was ≤ 60 s and were defined as abnormal when it was ≥ 100 s. Each examination was performed by same selected physicians. MAIN OUTCOME MEASURFS: The main outcome measurements included ① results of eye position examination and stereoptic examination in children in all age brackets, ② results of optometry in children with strabismus, ③ The relation between eyesight and stereopsis in participants,④Stereoacuity of children in all age brackets, ⑤and possible causations involve in stereopsis. RESULTS: Practically, 8326 participants receiving examinations of eysight and eye position entered the statistical analysis procedure, while an other 662 children were omitted for their poor expression for the examinations. ① Results of stereoptic examination and eye position examination for participants in all age brackets: 165 (2％) with strabismus, in which 89.7％were first diagnosed; 2016 (27.5) with myopia, whose stereoptic value were ≥ 100 s. ②Results of optometry in children with strabismus: 93.5％ esotropia occurred in children with hyperopia. The rate of hyperopia/myopia was not significantly different between exotropia and vertical strabismus.③ Relation between eyesight and stereoacuity of participants: 75.5％ children have a normal stereoacuity.With a decreasing in eyesight,the stereoacuity decreased (P ＜ 0.05 or P ＜ 0.01). ④ Stereoacuity of the children in all age brackets: With an increasing age, the rate of children with normal stereoacuity increased. ⑤ Possible causations involved in stereopsis: strabismal amblyopia might have the greatest influence on stereopsis. CONCLUSION: ①About 90％ children with strabismus were firstly diagnosed in the investigation. Causations responsible for abnormal stereopsis include ametropia, strabismus, and amblyopia, and so on. ② Concomitant esotropia has close relation with binocular accommodation, while exotropia and vertical strabismus are not linked to refractions. Stereoacuity decreases with a decreasing in eyesight. ③ The results of the investigation support the view that mature stereopsis is achieved early than 4 years old although certain variance of stereoptic development can be observed among individuals.

Objective To understand the risk factors of neurogenic pulmonary edema in the patients with severe hand foot and mouth disease(HFMD). Methods According to neurogenic pulmonary edema or not ,79 patients with severe HFMD were divided into two groups. The difference was analyzed on the clinical symptoms, signs,the outcomes of laboratory and electroencephalogram (EEG) examination between the two groups. Then the risk factors of neurogenic pulmonary edema was analyzed by logistic regression analysis.Results There were significant differences of the EV71 infection rate,high body temperature,myoclonia,limb weakness,the disability of eyeball regulation,tachycardia, hypertension or hypotension, the extension of capillary filling time, leucocytosist, creatine kinase isoenzyme, hyperglycaemia between two groups. However, there were no significant differences of fever, fever time, vomiting, somnolence, convulsion, limb tremor, c-reactive protein and EEG between two groups. Tachycardia, hypertension or hypotension, hyperglycaemia were significant risk factors for neurogenic pulmonary edema by logistic regression analysis. And hyperglycaemia was the most significant prognostic factor(odd ratio 27. 075, P = 0. 000 2). Conclusion Tachycardia, hypertension or hypotension,hyperglycaemia are the significant risk factors for neurogenic pulmonary edema. It is especially important for hyperglycaemia to predict neurogenic pulmonary edema.

ObjectiveTo investigate bronchial provocation test (BPT) and small airway function in children with cough variant asthma (CVA).MethodsA total of 353 children with chronic cough whose mean age was (7.45±2.58) years from three hospitals of Pudong district were enrolled during May 2012 and February 2014. Conventional pulmonary function tests, BPT and questionnaire survey were performed and the difference in pulmonary function was analyzed between children with positive BPT and negative BPT.ResultsIn 353 children with chronic cough, there were 200 children (56.66%) diagnosed as CVA with posi-tive BPT. Compared with BPT negative group, the percentages of nighttime cough and severe dry cough in BPT positive group were signiifcantly higher while the percentages of morning/daytime cough and wet cough were signiifcantly lower (P<0.01). Fur-thermore, the rates of history of atopic dermatitis and rhinitis in BPT positive group were signiifcantly higher than those in BPT negative group (P<0.01). Forced expiratory lfow at 75% relfecting the small airway function was signiifcantly lower in BPT posi-tive group than that in BPT negative group (P=0.032).ConclusionsBronchial hyperresponsiveness and decreased small airway function are the important pathological features of CVA. BPT and spirometry have clinical signiifcances in the CVA diagnosis and the analysis of cause of chronic cough.

Objective To study the clinical features and spirometry of children with chronic cough and positive findings by bronchial provocation test.Methods Four hundred and fifty children with chronic cough from 3 hospitals of Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong Medical University School of Medicine,Gong Li Hospital of Pudong New Area,Pudong Hospital,were enrolled in this study from December 2012 to December 2014,and among them,373 cases completed the questionnaires,spirometry and bronchial provocation test.The differences in clinical features and spirometry between the bronchial provocation test positive group and negative group were compared.And the further evaluation of their clinical value was performed.Results Two hundred and thirty-six cases of children with bronchial provocation tests positive showed much higher rate of dry [72.03％ (170/236 cases)] and night cough[58.90％ (139/236 cases)] than those in the negative group[27.00％ (37/137 cases),22.63％ (31/137cases)],and the differences were significant (x2 =71.154,45.973,all P ＜0.01).Children in positive group also had higher morbidity of eczema[52.12％ (123/236 cases)],allergic conjunctivitis [24.15％ (57/236 cases)] and inhaled allergy history[40.25％ (95/236 cases)] than those in negative group[32.85％ (45/137 cases),10.95％ (15/137cases),18.98％ (26/137 cases)],and there existed significant differences (x2 =13.006,9.701,17.904,all P ＜0.01).And they also had higher asthma heredity [18.22％ (43/236 cases)] than that in negative group [9.49％(13/137 cases)],and the difference was significant (x2 =5.179,P =0.023);with worse small airway function [50.85％ (120/137 cases) vs 36.50％ (50/137 cases)] (x2 =7.197,P =0.007).For further study,the sensitivity and specificity for dry cough were both high(72.03％ and 72.99％).For specificity,family history was the most highest one (90.51％),and night cough and allergic conjunctivitis were also high.Conclusions Pulmonary function tests to reflect small airway function abnormalities,combined with a family history of asthma and chronic cough in children related to eczema,allergic conjunctivitis,and inhalation allergy history clinical features,can better predict airway hyperresponsiveness.

Objective To study the clinical manifestation and MRI feature of toxic encephalopathy after inhaling caffeine and sodium benzoate. Methods Three patients with toxic encephalopathy induced by inhaling caffeine and sodium benzoate were observed clinically and with MRI. Results The 3 patients were male. They all had definite addiction histories (the time of addiction for 3 years to 7 years ). There were special language and retropulsive dystonia besides the common characteristics of toxic encephalopathy:reaction retardation and disturbance of intelligence. MRI showed the change of generalized demyelination in bilateral symmetrical cerebral hemisphere, posterior limbs of internal capsule, corpus callosum, medial lemniscus, and cerebellum hemisphere dentate nucleus. The clinical symptoms of 3 patients were significantly improved 40 days after the adrenocortical steroid and neurotrophic treatment. The mild mood disorder remained in case 1. Conclusion Clinical manifestation and MRI of toxic encephalopathy after inhaling caffeine and sodium benzoate are known, so we could diagnose the patients of the disease in time.

Background:Protein inhibitor of activated STAT 1( PIAS1 )is an important regulator for inflammatory signaling network,which is low expressed in gastric cancer and associated with development of cancer,but its mechanism has not been elucidated. Aims:To investigate the effect of PIAS1 on epithelial-mesenchymal transition( EMT)of gastric cancer under inflammatory microenvironment. Methods:Recombinant adenovirus Ad5/F35-PIAS1 and Ad5/F35-null were constructed and transfected into gastric cancer cell line SGC-7901,mRNA and protein expressions of PIAS1 were detected by RT-PCR and Western blotting,respectively. SGC-7901 cells were divided into IL-6 treatment group,Ad5/F35-PIAS1﹢IL-6 treatment group and Ad5/F35-null﹢IL-6 treatment group. Cell proliferation was measured by MTT method,migration and invasion capacities were assessed by wound healing test and Transwell chamber invasion assay. Protein expressions of E-cadherin,Snail,Twist,Vimentin and P-p38MAPK were assessed by Western blotting. Results:The transfection of Ad5/F35-PIAS1 significantly increased the expressions of PIAS1 mRNA and protein in SGC-7901 cells. Compared with IL-6 treatment group and Ad5/F35-null﹢IL-6 treatment group,capacities of cell proliferation,migration and invasion were significantly decreased(P ﹤0. 01);protein expressions of Snail,Twist,Vimentin and P-p38MAPK were significantly decreased while expression of E-cadherin protein was significantly increased in Ad5/F35-PIAS1 ﹢IL-6 treatment group ( P﹤0. 01). No significant differences in above-mentioned indices were found between IL-6 treatment group and Ad5/F35-null﹢IL-6 treatment group(P﹥0. 05). Conclusions:PIAS1 could inhibit EMT of gastric cancer cells under inflammatory microenvironment,and may play an important role in inhibition of tumor invasion and metastasis.

Background:Colorectal polyps,especially adenomatous polyps are the precusor of colorectal cancer. Screening and polypectomy by using colonoscopy is an important approach for prevention of colorectal cancer. Aims:To conduct a retrospective analysis among 1 613 cases of patients with colorectal polyps in Jiading District,Shanghai,China for guiding the management of colonoscopy surveillance of colorectal polyps. Methods:A total of 2 652 colorectal polyps detected by colonoscopy from Jan. 2013 to Aug. 2014 in the Endoscopy Center of Shanghai Ruijin Hospital Northern Branch were recruited in the study. Clinicopathological features of the polyps,coincidence rate of biopsy pathology and polypectomy pathology,and the re-detected polyps in colonoscopic follow-up were analyzed. Results:In 2 652 colorectal polyps,1 996 (75. 3% )were located in distal colon;adenomatous polyps accounted for 77. 5%(2 056 / 2 652)of the polyps detected by colonoscopy,of which 804(39. 1% )were found to have intraepithelial neoplasia. Both biopsy pathology and polypectomy pathology were obtained in 447 polyps,with an overall coincidence rate of 60. 4% ;as for adenomas,the coincidence rate was 68. 1% . Two hundred and eighteen pathologically proved polyps were found in a 1. 5-year colonoscopic follow-up, among which 74. 3% were adenomatous polyps;the re-detection rate of polyps located in proximal colon or less than 1. 0 cm in diameter was significantly higher than polyps located in distal colon and more than 1. 0 cm in diameter, respectively(12. 3% vs. 6. 9% and 9. 0% vs. 4. 5% ,P all < 0. 01). Conclusions:Adenomatous polyps account for high proportion of colorectal polyps detected by colonoscopy. Pathological examination of resection specimens and periodical follow-up are important for patients with colorectal polyps after endoscopic polypectomy.

Presented in this paper is a report on the Quadriplegia Index of Function(QIF) in usewith 16 cases of quadriplegic patients.Compared with the Barthel Index and Japan ADL Scale,QIF wasfound to be more sensitive and effective to document the small but significant funtional gains made byquadriplegics during medical rehabilitation,therefore,authors suggest that QIF should be widely usedin the rehabilitation evaluation of quadriplegic patients.
