Objective To study epidemiology, clinical findings, diagnosis and treatment of sepsis caused by Vibrio vulnificus. Method Patientss with Vibrio vulnificus sepsis were collected from 1995 to 2008. The medical records including epidemiological and clinical data were analyzed. Results The male-to-female ratio of 34cases was 4.7:1 and 76. 5% of these patients suffered from chronic liver disease. Most patients occurred from April to October with signs of abrupt fever, characteristic cutaneous lesions, hypotension and progressive multiple organ disfunction syndrome (MODS). The mortality was over 47.1% . The criteria proposed for early diagnosis of Vibrio vulnificus sepsis were abrupt onset with fever during the period from April to November, characteristic cutaneous lesions, such as the most commonly occurred haemorrhagic bullae on the extremities or even extensive necrosis of skin and muscular tissue, progressive hypotension or shock accompanied by MODS, pre-existing liver disease or chronic abuse of alcohol, and consumption of raw seafood or exposure to seawater within 12 week. Early administration of the third-generation cephalosporins with the quinolones in full dosage, aggressive wound debridement,appropriate dermoplasty and supportive care contribute to a better outcome. Conclusions Vibrio vulnificus sepsis progresses rapidly with high mortality. Early diagnosis, rapid treatment with prompt antibiotics and aggressive surgery treatment are very important to improve the outcome.

Objective To investigate clinical features,treatments and prognostic factors of the patients with necrotizing fasciitis caused by vibrio infections and thus provide reference for the early treatment and prognostic assessment.Methods A retrospective analysis was conducted on clinical data of 56 patients with vibrio necrotizing fasciitis admitted to the emergency center of our hospital from May 1995 to June 2011.The clinical characteristics and treatments of the patients were summarized,and differences of clinical factors between the survival group and death group were compared.The possible influencing factors for prognosis were also analyzed.Results The main clinical manifestations included fever (61％),shock (84％) and organ dysfunction,of which renal insufficiency (88％) was the most common,with case fatality of 43％.Early pathological changes of limbs were only local swelling and pain,while skin ecchymosis,tension blood blisters,necrosis and subcutaneous crepitation were the signs of advanced stage.Comprehensive treatment regime including early administration of sensitive antibiotics plus surgical incision and drainage and medicine support was given.A series of factors were significantly different between the survival and death groups including the duration from the presentation of symptoms to hospital admission (P ＜ 0.05 ),limb lesions involving the trunk (P ＜ 0.01 ),creatine kinase level (P ＜ 0.05 ),and emergency incision and drainage ( P ＜ 0.01 ).Conclusions The most prominent clinical manifestations of vibrio necrotizing fasciitis are rapidly progressive local symptoms and signs,and sharp deterioration of systemic conditions.Delayed visiting,severe local lesions,and failure to emergency surgery may be the factors for poor prognosis.

Objectives:To investigate the effect of resistance exercise(RE)on the dissolution of catheter-associated thrombus(CRT)and its possible mechanism.Methods:A total of 36 male SD rats were randomly divided into control group,CRT group,CRT+ RE group(n=12 in each group).Rats in the CRT group did not receive any intervention,while rats in the CRT+RE group received RE intervention 10 days after modeling for 28 days.The thrombolysis rate was evaluated by Hematoxylin-Eosin staining.The contents of irisin,interleukin(IL)-6 and IL-10 in serum were detected by ELISA.The relative mRNA expression levels of peroxisome proliferator-activated receptor γ coactivator α(PGC-1α)and fibronectin type Ⅲ domain-containing 5(FNDC5)in gastrocnemius were detected by real-time quantitative PCR(qPCR).Results:There was no thrombosis in control group.Compared with control group,the contents of irisin and IL-10 in CRT group were significantly decreased,while the content of IL-6 in CRT rats was significantly increased(all P<0.01).Thrombolysis rate was significantly higher,and the mRNA expressions of PGC-1α and FNDC5 in gastrocnemius were significantly upregulated in CRT+RE group than in CRT group(all P<0.01).Serum irisin,IL-10 contents were significantly increased,IL-6 content was significantly lower in CRT+RE group than in CRT group(all P<0.01).Conclusions:Resistance exercise for 28 days could promote the dissolution of CRT,which may be related to the up-regulation of irisin expression and the inhibition of inflammation.

Solitary cervical submental nodule is a relatively rare case in clinical procedure and prone to miss diagnosis.Differential diagnosis with various head and neck diseases is necessary.This article reported a case of solitary cervical submental metastasis of papillary thyroid carcinoma received in the department of surgery,Civil Aviation Shanghai Hospital,Ruijin Gubei Branch,Shanghai Jiao Tong University School of Medicine.The patient came to the outpatient clinic for treatment due to"consciously larger submental tubercle than before".Ultrasound examination revealed suspicious lesions in both the thyroid and submental regions.Ultrasound-guided final needle aspiration biopsy diagnosed as malignant tumor.Surgical resection was performed and the central group lymph nodes dissected Pathological examination confirmed papillary thyroid carcinoma with solitary submental metastasis.This article reported the clinical diagnosis and treatment of this case,in order to improve the disease recognition for clinicians,and make differential diagnosis with other rare neck diseases,and avoid missing diagnoses.
