BACKGROUND:Femoral offset reconstruction is significant for recovering strength of abductor and the balance of soft tissue tension surrounding hip joint, maintaining joint stabilization, restoring joint function, reducing limping after replacement, decreasing prosthetic abrasion, and the incidence of joint prosthesis dislocation.
OBJECTIVE:To discuss effect of femoral offset reconstruction on hip joint function in total hip arthroplasty.
METHODS:We comparatively analyzed 20 patients (20 hips) undergoing the modular prosthesis (S-ROM) total hip arthroplasty and 19 patients (20 hips) undergoing the one modular prosthesis (Corail) total hip arthroplasty at the same time. According to Harris hip score and radiography results, hip joint function and femoral offset reconstruction rate were comparatively studied in both groups.
RESULTS AND CONCLUSION:No infection, fracture, dislocation, deep venous thrombosis or neurovascular injury occurred in either group. Clinical fol ow-up results:In the modular prosthesis and one modular prosthesis groups, there was no significant difference in preoperative Harris hip score between the femoral offset reconstruction and non-reconstruction groups (P>0.05). At 12 months and the latest fol ow-up, the Harris hip score was higher in the patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P<0.05). The range of abduction of hip joint was larger in patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P<0.05). Radiographic fol ow-up results:significant differences in the rate of femoral offset reconstruction were detected between the modular prosthesis and one modular prosthesis groups (χ2=3.956, P<0.05). 39 (98%) femoral stems were in neutral position and one (2.5%) was in mild valgus. There was no significant difference in the abduction angle and the anteversion angle between patients with and without femoral offset reconstruction (P>0.05). These results indicated that functional recovery and the range of abduction were better in patients with femoral offset reconstruction than those without femoral offset reconstruction. Modular prosthesis has a high rate of femoral offset reconstruction.

Objective To analyze the genetic characteristics of the complete genome of a human echovirus 30 (Echo30) KM/A363/09 strain isolated in Yunnan, China in 2009.Methods Primers specif-ic for Echo30 were designed .The extracted RNA was amplified by using RT-PCR.Seven fragments covering the complete viral genome were sequenced and the complete sequences were aligned with other sequences of enterovirus reference strains downloaded from Genbank . By using Mega5.1, Geneious, RDP3 and SimPlot3.5.1 softwares, the phylogenetic and recombination analysis were carried out .Results The com-plete nucleotide sequence of KM/A363/09 isolate was 7425 bp in length, encoding 2194 amino acids.KM/A363/09 isolate was highly similar with Bastianni prototype strain showing the homology of 81.2%in nucle-otide and 95.8%in amino acid.The eight Echo30 isolates shared 81.2%-88.6%homologies in nucleotide sequences and 95.8%-97.8%in amino acid sequences .Phylogenetic analysis showed that the KM/A363/09 strain belonged to one clade of Echo 30 in China.The genetic recombination of KM/A363/09 isolate was detected in the non-structural region .Conclusion KM/A363/09 isolate belongs to one clade of Echo 30 in China indicating that the evolution of Echo 30 has occurred in China .

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

Enterovirus 71 (EV71) is a common cause of Hand, foot, and mouth disease (HFMD) and may also cause severe neurological diseases, such as encephalitis and poliomyelitis-like paralysis. To examine the genetic diversity of EV71, we determined and analyzed the complete VP1 sequences (891 nucleotides) from nine EV71 strains isolated in Fuyang, China. We found that nine EV71 strains isolated were over 98% homologous at the nucleotide level and 93%-100% homologous to members of the C4 subgenogroup. At the amino acid level, these Fuyang strains were 99% -100% homologous to one another, 97%-100% homologous to members of the C4 subgenogroup, and the histidine(H) at amino acid position 22 was conserved among the Fuyang strains. The results indicate that Fuyang isolates belong to genotype C4, and an H at position 22 appears to be a marker for the Fuyang strains.
