?AlM:To observe the eye complications in the cases of acute chlorine gas poisoning.
?METHODS:A retrospective review of 121 cases of acute chlorine gas poising with eye irritation, dry eye and other eye complications in Linyi People’s Hospital from February 2009 to February 2013 was performed.
?RESULTS: Among 121 patients, 117 cases ( about 96. 7%) had complications of eye irritation and conjunctival and corneal epithelial damage, and the ocular surface damage was aggravated with the increasing level of chlorine gas poisoning. After 3, 6mo being discharged, 32 and 7 patients respectively occurred dry eye among 115 patients followed up. One mild chlorine poisoning patient, during the hormonotherapy of pulmonary complication, complicated with bullous retinal detachment, of which symptoms and physical signs had been improved after stopping hormonotherapy and adding drugs facilitating fluid absorption. One severe chlorine poisoning patient with loss of consciousness during the treatment, had corneal ulcer and after ulcer being healed with drug and conjunctival flap covering surgery, was left permanent leukoma cornea.
?CONCLUSlON: Acute chlorine poisoning can cause corneal and conjunctival epithelial damage and dry eye. Ocular complications like bullous retinal detachment associated with hormone application should be paid more attention to in the hormonotherapy. For some patients with severe poisoning, the therapy of corneal and conjunctival epitheliums should be taken seriously in case of irreparable damage in rescuing patient’s life.

Objective To study the clinical features and treatment of 12 cases of lupus vulgaris.Methods A comprehensive study was performed on 12 patients with lupus vulgaris.The clinical and histopathological features,misdiagnosis,treatment and prognosis of this entity were analyzed.Results Of these patients,83.3％ had a history of local trauma before the occurrence of lupus vulgaris.All the patients showed an early onset and long clinical course of lupus vulgaris,absence of obvious symptoms and variety in skin lesions.Lupus vulgaris was misdiagnosed at the first visit in all the patients.The final diagnosis was confirmed by histopathology,purified protein derivative (PPD) test,acid-fast staining,Mycobacterium tuberculosis culture,DNA sequencing,etc.Satisfactory outcomes were achieved in these patients after standard anti-tuberculosis treatment.Conclusions Lupus vulgaris is easy to be misdiagnosed and improperly treated due to its complicated clinical features.Clinicians should expand their knowledge about this entity,which can be diagnosed by histopathology and culture.

Objective To study the detection rate of early esophageal carcinoma using magnifying endoscopy,and to evaluate the relationship between the imaging patterns of microvasculature change and his- tological diagnosis.Methods Two hundred and fourteen patients with esophageal mucosa roughness,ero- sion,plaque,abnormal color and indentation in conventional endoscopy and 16 healthy volunteers were en- rolled.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL)changes after iodine dyeing.The biopsies underwent pathologic evaluation.The comparison be- tween the imaging patterns of endoscopy and histological diagnosiswas was evaluated.Results 80.4%(90/ 112)esophagitis was type 2,and 85.7%(12/14)early esophageal carcinoma was type 3 and type 4.The difference was significant between early esophageal carcinoma and normal mueosa(?~2=27.32,P

Background Leber hereditary optic neuropathy (LHON)is a common inherited eye disease,which generally affects young adults with bilateral loss of central vision.Mutation frequency of Leber hereditary has not been fully clarified. Objective This study was to investigate the mutation frequency of mitochondrial NDI gene associated with LHON in Chinese population. Methods The proposal of the study was approved by Ethic Committee of Wenzhou Medical College.Written informed consent was obtained from each subject initial of this trial.Eight hundred and ninety-four LHON patients and 134 normal subjects were collected.Genomic DNA was extracted from peripheral blood leukocytes of the all participants.Polymerase chain reaction (PCR) was used to amplify and sequence analysis of the mitochondrial ND1 gene was performed and aligned with revised Cambridge Reference Sequence(rCRS) of mitochondrial DNA.Then mutated gene frequency was screened and analyzed. Results Mutational analysis of mitochondrial ND1 gene in 894 LHON patients revealed the presence of G3316A,T3394C,G3460A,C3497T,G3635A,G3733A,and T4216C.11.19％ LHON patients (100/894 ) were found to be associated with the gene mutations mentioned above,and 3.24％ patients (29/894) showed the co-occurrence of three primary mutations.Mutation frequencies in LHON patients were 2.57％,2.23％,1.45％,3.80％,0.67％,0.11％,0.34％,respectively,and G3316A,T3394C,C3497T and T4216C also were detected in 134 normal controls with the mutation frequencies of 4.48％,2.99％,4.48％ and 1.49％,respectively.Mutation frequency analysis showed an insignificant difference in the mutations of G3316A,T3394C,C3497T and T4216C between LHON patients and normal controls (x2 =0.926,P=0.336;x2 =0.052,P=0.820; x2 =0.142,P=0.707;P=0.129).G3376A,G3496T,G3700A,A4136G,T4160C and C4171A were absent in Chinese LHON patients. Conclusions Mitoehondrial ND1 gene in LHON is a mutational hotspot in Chinese population,11.19％ (100/894)associated with LHON was caused by ND1 gene mutation.G3635A,G3733A may be rare pathological mutation in Chinese population.However,G3316A,T3394C,C3497T and T4216C are insufficient to produce the clinical phenotype,but they may play a synergic role for penetrance and phenotypic manifestation in LHON.

UNLABELLED: Abstract: OBJECTIVE: To investigate the bacterial succession on rat carcasses and to evaluate the use of bacterial succession for postmortem interval (PMI) estimation. METHODS: Adult female SD rat remains were placed in carton boxes. The bacterial colonization of circumocular skin, mouth and vagina was collected to be identified using culture-dependent biochemical methods. The changes in community composition were regularly documented. RESULTS: The bacterial succession in three habitats showed that Staphylococcus and Neisseria were predominated in early PMI, especially Staphylococcus aureus and Neisseria lactamica in 6 hours after death. Lactobacillus casei developed on the 3-4 days regularly, and kept stable at a certain level in late PMI. CONCLUSION The involvement of normal and putrefactive bacteria in three body habitats of rat remains can be used for PMI estimation.

OBJECTIVETo discuss the epidemiological and clinical characteristics of the hospitalized children with hand foot and mouth disease (HFMD) in Yantai area.

METHODSEpidemiological and clinical data of HFMD children from 2009 to 2010 were summarized and analyzed retrospectively.

RESULTSMost of the infected (94.6%) were under 5 years old and the ratio between male and female was 1.5: 1. Oral mucosal pox or ulcer as well as hand and foot rashes were observed in all 931 patients. Fever and neurological disorders occurred in 840 (90.2%) and 121 (13.0%) patients respectively. The incidence was positively correlated with air temperature (r = 0.887, P < 0.001), with a peak in April to September (88.9%). The ratio of children from countryside, total duration of fever, serum concentration of c-reacting protein (CRP) and fasting blood glucose (FBG) were significantly higher in severe cases than in those mild ones. Multivariate analysis showed longer mean duration of fever( Odds ratio [OR], 1.491; 95% confidence interval [ CI] 1.170-1.901; P = 0.001) and hyperglycemia (OR, 1.124; 95% CI 1.016-1.245; P = 0.024) were independent risk factors of severity.

CONCLUSIONChildren younger than 5 years old are susceptible to HFMD and most cases occur in April to September. The monthly incidence is positively correlated with temperature of that month. Longer duration of fever and hyperglycemia are independent risk factors for severity. Most cases could have a favorable prognosis after timely diagnosis and proper intervention.
