Objective To evaluate factors which maintain the stability of the ankle, and discuss indications for trans-syndesmotic fixation. Methods 12 freshly-frozen cadaver legs amputated below the knee were collected and divided into 2 groups. An ankle fracture model of unconstrained pronation-external rotation was then designed. Group A simulated the injury combined with medial malleolus fracture, and Group B the injury combined with deltoid tear. Ligaments were cut off sequentially to simulate the increasing severity of the injury. Fuji super low-pressure sensitive films and displacement transducers were used to measure the contact area of the tibiotalar articular surface and the width of the syndesmosis. The data were analyzed with SPSS to analyze the relationship of ligament injury and ankle stability. Results In Group A, the articular contact area and the syndesmotic width after section of the deltoid were significantly different from those before the section (P

To identify the genotype and analyze the molecular characteristics of dengue virus strain SZ0524 isolated from serum samples of patients with early stage of dengue fever in Shenzhen in 2005 so as to explore its possible origin. The C6/36 cell line was cultivated with virus strain SZ0524 and its suspension was harvested. The type of isolated virus strain was determined by RT-semi-nested PCR and fluorescent PCR. E gene of isolated virus strain was amplified by RT-PCR and sequenced. Homology and phylogenetic tree of E gene of this dengue virus with the strains isolated from other areas were constructed. This SZ0524 strain was further identified by fluorescent PCR, and confirmed to be the type 4 virus after obtaining the 392bp band with type 4 specific primers. The homology of nucleotide sequence of E gene of SZ0524 strain with the standard type 4 dengue virus H241 strain were 99.7%, but the homology with the standard dengue virus 1,2,3 in the same fragment were 57.0%, 59.2% and 56.2% respectively. Analysis of the phylogenetic tree indicated that SZ0524 was more close to D4-73NIID and D4-61NIID strain, next to H241 strain, and they lied in the same branch of phylogenetic tree. The isolated dengue virus type 4 belonged to genotype Ⅰand the SZ0524 strain was proved to be dengue virus type 4 in the molecular level. Combined with epidemiology information, it is suggested that this case can be classified as an imported case and the SZ0524 strain may be transferred from the southeast asian region.

OBJECTIVETo investigate the diagnostic value of liquid-based cytology test (LCT) in pancreatic lesions sampled by ultrasound-guided fine needle aspiration (EUS-FNA).
METHODSA retrospective analysis of 556 cases of LCT smears sampled by EUS-FNA of pancreatic lesions was performed, and 164 cases had histologic diagnosis with subsequent surgical resection or biopsy and immunohistochemistry. The accuracy of the cytologic diagnosis was assessed using the histologic diagnosis as the gold standard. The discrepant cases were reviewed to identify sources of errors.
RESULTSThe satisfactory rate for EUS-FNA was 96.0%(534/556). The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were 87.7%(128/146), 13/16, 97.7%(128/131), 41.9%(13/31) and 87.0%(141/162) respectively. The diagnostic accuracy was lower in cystic lesions than that in solid lesions. The LCT sensitivities of adenocarcinoma, lymphoma and neuroendocrine tumors were higher than those of cystic tumors and mesenchymal tumors. False positive diagnosis was mainly due to epithelial abnormalities in inflammatory reaction. False negative diagnosis was mainly due to scanty or lack of tumor cells in the smears, or mild atypia that was insufficient for diagnosis.
CONCLUSIONSEUS-FNA is a valuable tool for the diagnosis of pancreatic lesions. Standardized terminology and nomenclature are helpful to improve the diagnostic accuracy.

Objective To analyze the genetic characteristics of VP1-VP4 genes carried by cox-sackievirus A6 (CVA6) strains isolated from severe cases of hand, foot, and mouth disease (HFMD) in Shenzhen during 2012 to 2015. -ethods The VP1-VP4 genes of CVA6 strains isolated from severe HFMD cases in Shenzhen during 2012 to 2015 were amplified and sequenced. Phylogenetic analysis was performed to analyze the VP1-VP4 genes of CVA6 isolates and sequences downloaded from GenBank by using DNASTAR6. 0 and MEGA6. 02 software packages. Results Four cases of severe HFMD were caused by CVA6 in Shenzhen during 2012 to 2015. All of the patients had the symptom of fever, skin rash and aseptic encephalitis. The CVA6 strain causing severe HFMD in 2013 shared 98. 8%-98. 9% homology in nucleotide sequences and 99. 3%-99. 8% in amino acid sequences with the strains isolated in 2012. Two amino acid mutations were found in the CVA6 strain isolated in 2013, which were G73E in VP2 region and S13G in VP1 region. However, the CVA6 strain isolated in 2015 only shared 95. 0% homology in nucleotide sequences and 99. 3% homology in amino acid sequences with the strain isolated in 2013. Six amino acid mutations were identified including E73G in VP2 region and T5A, S27N, A30V, N137S and V242I in VP1 region. The phylogenetic analysis revealed that the four CVA6 strains belong to D3 sub-genotype. The CVA6 strains causing severe cases in 2012 had the nearest genetic relationship with the strain isolated in Changsha in 2012 (KJ156349). The CVA6 strain isolated in Shenzhen in 2013 had the nearest genetic relationship with the strain isolated in Shanghai in 2013 (KJ612513). The Shenzhen CVA6 isolate in 2015 showed high similarity to Weifang CVA6 isolate in 2014 (KX752785). Conclusions All CVA6 strains causing severe HFMD ca-ses in Shenzhen during 2012 to 2015 belongs to D3 sub-genotype. Mutations of S27N and A30V in the VP1 region of the CVA6 isolate in 2015 are located in the B cell epitopes. In addition, the VP1-V242I mutation in the CVA6 strain isolated in 2015 is located in the binding site of PSGL-1 receptor. These mutations may affect the binding of CVA6 strains to the cellular receptors and their infectivity to people.
