Objective To analyze the complete genome sequence of a Shenzhen coxsackievirus A2 strain CVA2-SHZH13-01 and its evolution.Methods RT-PCR was used to amplify the complete genome of CVA2-SHZH13-01 strain.The PCR products were purified and sequenced to analyze their genetic character-istics.Results The complete genome of CVA2-SHZH13-01 strain was 7400 bp in length, encoding 2191 amino acids.CVA2-SHZH13-01 strain was highly similar with the novel recombinant CVA2-HK (431306) strain isolated from Hong Kong sharing the nucleotide homology of 98.3%, 98.8%, 99.0%, 99.2%, 98.8%and 98.9%in 5′UTR, P1 ( VP1 to VP4) , P2, P3, 3′UTR regions and complete genome, respec-tively.CVA2-SHZH13-01 strain was highly identical to the international standard strain CVA2-Fleetwood showing the homology of 81.6% in nucleotide sequences in P1 region, but closely associated with EV71-SHZH03 and EV71-GD2009 strains (82.8%-88.7%) in P2 and P3 regions.The phylogenetic analysis in-dicated that CVA2-SHZH13-01 strain belonged to the CVA2-HK (431306) variant.Data from analysis of amino acid in P1 region showed that there were three amino acid mutations in CVA2-SHZH13-01 strain including aa5L→F, aa666S→G and aa671T→I as compared with CVA2-HK (431306) strain.Conclusion CVA2-SHZH13-01 strain belonged to CVA2-HK (431306) variant.

Objective: To assess the technique, efficacy, security and side effects of percutaneous ethanol injection(PEI) in treating the cystic thyroid adenomas. Methods: Fifty seven patients(male 34, female 23) with unilateral and solitary benign cystic thyroid adenoma received PEI therapy under high resolution ultrasound guidance. The medial age of the patients was 47 years(ranging 29 62). The mean diameter in the largest section of the thyroid adenomas was (37.55?5.64) mm(17 59 mm). The thyroid lesions in 12 patients consisted of cystic lumen mixed with solid structure, and the rest 45 had entire cystic thyroid lesions. Ultrasound reexamination of thyroid lesions was done 3 months after the initial treatment. Significant curative effect was defined as an adenoma volume shrinkage rate larger than 50%. The efficacious result was defined as a volume shrinkage rate between 40% and 50% together with a further shrink over a 6 month duration follow up. Those patients with adenoma volume shrinkage rate less than 40% underwent a second PEI after 6 months. Results: Over a mean duration of 25.5 months follow up, 66.7% subjects with entirely cystic had significant curative outcome; 19.3% subjects had efficacious result; and 9.8% subjects needed a second PEI and their thyroid lesions contained more solid tissue. There were 5.3% subjects were transfered to open surgery due to colloid cyst fluid. Twenty one patients complained of intraoperative local transient pain; 15 patients had transient pyrexia in the 48 h after injection, and 3 patients were affected by post operative transient dysphonia. No serious bleeding were encountered, and no apparent change of serum T 3,T 4,TSH level was observed. Conclusion: Ultrasound guided PEI therapy is an effective, safe and simple procedure for the ablation of cystic thyroid adenoma. Careful selection of subjects according to their preoperative thyroid ultrasonographies can reduce the unsuccessful PEI. A selective volume of ethanol injection consistent with the adenoma size on sonograms and a thorough flush with ethanol can improve the efficacy of PEI.

Aim To investigate the effects of maternal chronic aluminum exposure on memorial behaviour and hippocampal intracellular Ca2+ concentration ([Ca2+]i)on their offspring after the induction of LTP(long-term potentiation). Methods Adult Wistar rats (150~200 g) were exposed to aluminum by drinking distilled water, the concentration of AlCl3 is 0.015 mol?L-1(2 g?L-1) and 0.03 mol?L-1(4 g?L-1) aluminum chloride (AlCl3) solution, respectively, for 30 days prior to mating and during the whole gestation and suckling period. Their offspring were distributed into three experimental groups: control group; two exposed groups (represented by 0.2%-Al and 0.4%-Al ) administrated aluminum exposure ended at postnatal day 21. The brain tissue and blood aluminum levels were measured by Atomic absorption spectrometry (AAS). Memorial ability of the offspring was tested by Step down test.[Ca2+]i was measured by the technique of Fura-2/AM calcium ions fluorescence indicator. Results The mean aluminum content in blood and brain tissue was significantly higher than the control group(P0.05), but was significantly decreased in 0.4%-Al exposed group(P

OBJECTIVETo explore the effect of half circle external fixation for the treatment of open tibial fractures.

METHODSFrom March 2005 to March 2011, 94 patients with open tibiofibula fractures were treated by closed manipulative or Kirschner-wire poking reduction with half circle groove external fixation including 63 males and 31 females with an average age of 39 years old ranging from 17 to 65 years old. Among these patients, 5 cases were cross shaped fractures, 19 were oblique form and spiral fractures, 70 cases were comminuted fractures. According to the fracture Gustilo classification, 49 cases were type IIIA, 45 were type IIIB. The incidence of wound infection, fracture healing time were observed. The function was evaluated according to the Johner-Wruhs standard.

RESULTSAll patients were followed up for 14 to 63 months (averaged 29 months). The wound healing time was from 16 to 39 weeks (means 21.4 weeks). No fracture nonunion, osteomyelitis and calf compartment syndrome occurred. The wounds of 81 cases were healed at the first period,deep wound infection occurred in 2 cases. According to the function Johner-Wruhs evaluation criteria:the result was excellent in 52 cases, good in 37 cases, fair in 5 cases.

CONCLUSIONClosed manipulative or Kirschner-wire poking reduction and half circle groove external fixation can reduce the infection rate of open tibiofibula fractures. For open tibiofibula comminuted fractures, after the half circle groove external fixation for 3 to 6 weeks, a middle Kirschner-wire was removed according to fracture end healing situation to make fixation dynamic and promote fracture healing.
