Objective To analyze characteristics of pathogenic microbiology and antimicrobial susceptibility of Vib-rio vulnificus (V.vulnificus)causing infection in patients at a hospital in Shantou City. Methods Four patients with V.vulnificus infection admitted to a hospital between June 2013 and June 2014 were analyzed retrospectively, blood specimens of patients were collected for culture,blister fluid and wound secretion were taken and inoculated on blood agar plates,MacConkey agar plates,and thiosulfate citrate bile salts sucrose (TCBS)plates,isolated strains were identified and performed antimicrobial susceptibility testing. Results Among 4 patients with V. vulnificus infection,3 died,1 was cured;patients developed primary septicemia and lower extremity infection be-cause of eating pickled crab,steamed scallop,or contacting with seafood products after trauma. Blister fluid from patients A and B,wound secretion from patient C,and blood from patient D were all isolated oxidase-positive gram-negative bacteria which produced green colonies on TCBS plate,these strains were identified as V.vulnificus, which were resistant or intermediate to cefazolin,intermediate to cefotetan,and 1 strain was resistant to cefepime. Conclusion Four patients infected with V.vulnificus have high mortality rate (3/4),positive rates of blister fluid and wound secretion are higher than blood;timely medical consultation,early antimicrobial therapy,and active de-bridement will help to cure the disease.

Objective To study the expression of distintegrin and metalloprotease (ADAM10) in serum of lung cancer patients and its clinical significance. Methods The serum protein level of ADAM10 was assayed by ELISA in 44 lung cancer patients,34 benign lung lesions and 31 healthy subjects. The serum protein level of CEA was assayed by radioimmunoassay. Results The serum concentration of ADAM10 and CEA was higher in patients with lung cancer than benign lung lesions and normal controls(P <0.01) ,theft was distinct statistical difference be-tween lung cancer and lung benign lesions,normal controls(P <0.01) ,but no statistical difference between lung be-nign lesions and normal controls(P >0.05) ; the serum concentration of ADAM10 of lung cancer with lymph node metastasis were significantly higher than those of lung cancer without lymph node metastasis, there was statistical difference (P < 0.01) ; the serum concentration of CEA of lung cancer with lymph node metastasis were slightly higher than those of lung cancer without lymph node metastasis, but there was no difference (P > 0.05) ; the serum concentration of ADAM10 and CEA in adenocarcinoma were higher than squamous cell carcinoma and small cell lung cancer(P <0.01 ,P <0.05). The single item detection of ADAM10 or CEA to the lung cancer diagnostic sensitivity is 51.7% ,56.9% respectively,the union detection reaches 84.5% . Conclusion ADAM10 is related with occur-rence and metastasis in lung cancer. The union detection of ADAM10 and CEA can raise the lung cancer diagnostic sensitivity.

Objective To investigate the experiences of total hip replacement in the treatment of different types of osteoarthritis secondary to acetabular dysplasia, and evaluate its effect. Methods From January 1999 to December 2006, 37 hips in 35 cases with osteoarthritis secondary to acetabular dysplasia undergoing total hip replacement were included in this study. Preoperative Harris score was 30-64 points, with an average score of 45 points. Undergoing total hip replacement with complete release, of soft tissue, original acetabular, and no femoral osteotomy. Crowe Ⅰ , Ⅱ-type acetabular dysplasia chose conventional cementless press-fit prosthesis;Crowe Ⅲ,Ⅳ-type,chose the appropriate trumpet,Zweymüller system cementless acetabular biconical spiral surface and thin and straight SL rectangular hip stems. Results The duration of follow-up ranged from 12 to 60 months (average 24 months). No case appeared dislocation, periprosthetic fractures, femoral nerve and sciatic nerve injury and other complications, no clinical and X-ray findings of prosthesis loosening occurred. Postoperative Harris score was 60-95 points, and average was 85 points. Conclusion Adequate preoperative preparation, intraoperative complete release, is the key of the treatment and restoration of limb length.
