Objective To observe the effects of multidisciplinary rehabilitation on early heterotopic ossification of patients with traumatic elbow joint injury.Methods 80 work injury patients of early heterotopic ossification after traumatic elbow joint injury were randomly divided into the experiment group(42 cases) and control group(38 cases).The experiment group received multidisciplinary rehabilitation,including physical therapy,occupational therapy,physical factor therapy,traditional Chinese medicine,ward rehabilitation and vocational training.The control group was treated with pain killer and diminish inflammation medicine and median frequency electrical therapy.Range of motion(ROM) of joint and visual analogue scale(VAS) were separately assessed before and after 3 months treatment.Results After 3 months treatment,ROM and VAS of the experiment group were significantly changed compared with admission(P<0.01).The effectiveness of the experiment group was superior to that of the control group(P<0.05).After discharge,39 cases returned to primary work,3 cases changed work in the experiment group,and after 1 year follow-up,no case needed to receive operation.Conclusion In the early stage of heterotopic ossification after traumatic elbow joint injury,multidisciplinary rehabilitation can significantly relax clinical signs,improve functions and make the work injury patients return to work.

Objective To investigate the application value of spatio-temporal image correlation (STIC) combined with tomographic ultrasound imaging(TUI) in the prenatal diagnosis of conotruncal defects(CTD).Methods Two-dimensional(2D) fetal echocardiography to screen and TUI-STIC volumes from 1508 cases of fetuses of high risk with congenital heart disease.Postnatal work-up and pathological results were available for all fetuses with CTD.Results Thirty nine cases with CTD were found by TUI-STIC while thirty five cases were found by 2D echocardiography,but TUI-STIC had new findings and corrected the diagnosis in 9 cases as compared with 2D echocardiography.The sensitivity,specificity,positivity predictive value,negative predictive value and accuracy of TUI-STIC in evaluating CTD were 97.5 ％,100％,100 ％,99.9 ％ and 99 ％.The Kappa value of consistency test between 2DE and TUI-SIC was 0.244(P ＜ 0.01),McNemar test showed that the difference was statistically significant (P ＜ 0.01).Conclusions TUI-STIC allows a complete sequential analysis of fetal conotruncal defects and supplying additional information over 2D fetal echocardiography,it could improve the prenatal diagnosis rate.TUI-STIC is helpful in diagnosis of prenatal conotruncal defects.

Objective To exclude false positivities in detection of IgM antibodies against hepatitis E vires of genotype 4 (HEV-4) using a truncated immunodominant polypeptide of HEV open reading frames (ORF2). Methods The recombinant ORF2 immunodominant polypeptide corresponding to amino acids (AA) 459-607 and a truncated polypeptide corresponding to AA 472-607 were separately applied to coat ELISA plates. Anti-HEV IgM from 35 serum samples with HEV RNA positive, 69 serum samples from healthy individuals and 117 clinically suspicious HEV RNA positive serum samples was detected by an indirect ELISA and was confirmed by western blot in protein level and RT-PCR detecting in RNA level. Results Western blot analysis showed that the sera from HEV patients reacted with the dimmer of peptide 459-607, but they didn't react with the monomer and peptide 472-607. The ELISA showed that all 35 serum HEV RNA positive samples reacted with peptide 459-607 but not with peptide 472-607 and none of the 69 serum samples from healthy individuals reacted with either polypeptide. Among 117 chnically suspicious HEV RNA serum samples, 5 samples reacted simultaneously with both polypeptides. But the difference between 450 nm absorbance (A450) value was less than 0. 5. Western blot analysis demonstrated that all the 5 serum samples were anti-HEV IgM- negative. The 5 serum samples was detected negative by RT-PCR, indicating that the false pesitivities were caused by non-specific absorption. Conclusions ORF2 peptide 459-607 may be used to detect anti-HEV lgM efficiently. The false positivities caused by non-specific absorption can be largely excluded according to the difference between 45Ohm absorbance (A450) value when serum reacts with both polypeptides.

Objective To characterize the dimerization and the antigenicity of the ORF2 polypep-tide of hepatitis E virus (HEV, genotype 4). Methods HEV ORF2 gene was cloned from the serum of a patient with hepatitis E. The genotype was determined by sequencing. Three ORF2 polypeptides differing in size and other polypeptides with point mutations were produced in E. coli. The recombinant polypeptides were purified and analyzed by SDS-PAGE and Western blot. Results The ORF2 polypeptide containing 459-607 amino acid formed homedimer even in 8 mol/L urea. The truncated polypeptides containing amino acid 472-607 or 459-594 formed monomer only. The mutations at amino acid 562 or 595 disrupted the ho-modimer, whereas the mutations at amino acid 476 or 580 did not. Anti-HEV from hepatitis E patients only reacted with the homodimer form of the polypeptide 459-607 and did not react with monomer or tnmcated pol-ypeptides. Conclusion The amino acid 459-607 of HEV ORF2 is essential for dimerization of the ORF2 polypeptide. Residues at amino acid 562 and 595 are critical for the dimerization. The antigenicity of the polypeptide 459-607 mainly depends on its homodimer form.

BACKGROUNDTo characterize the intertype epitopes on human adenovirus (HAdV) hexon.

METHODSBased on computerized analysis on adenoviruses sequence of genomic alignment, antigenicity prediction and 3-D structure characteristics of hexon subunit, several peptides of hexon of adenoviruses were chosen to be synthesized or recombinant proteins of the hexon were expressed in E. coli by use of PGEX-5X. To identify the existence of intertype epitopes, the antisera raised with synthetic peptides or purified recombinant proteins were analyzed with Western blot and immunofluorescent assay.

RESULTSThe results of Western blot indicated that both peptide and recombinant antibodies showed specific reactivities with hexons of HADv-3, 4, 7 individually. Meanwhile, typical stain of immunofluorescence was found on HeLa cells infected with these HAdV by incubation with peptide as well as recombinant antibodies. Also, antibodies raised against peptide recognized the recombinant hexon protein in which a corresponding region of peptides was covered.

CONCLUSIONSMost of the predicted intertype epitopes of HAdV hexon wer e exclusively found in synthetic peptides and recombinant proteins. These intertype epitopes showed to be continuous and sequential which could be employed for development of antibodies of diagnostic use.

Objective To evaluate the effect of health education path on advanced schistosomiasis patients with splenomega-ly in perioperative period. Methods A total of 60 advanced schistosomiasis patients with splenomegaly in perioperative period were randomly divided into an observation group and a control group (30 cases each group). The patients in the observation group were intervened by the nursing and health education from admission to discharge according to the standardized process of health education path,while those in the control group were implemented with the conventional health education. Then the satis-faction of nursing work,hospital stays,hospitalization expenses and mastery of health knowledge of the patients in the two groups were investigated and the results were compared. Results The satisfaction rates of nursing work of patients in the obser-vation group and the control group were 90%and 60%,respectively,the difference between them was statistically significant (χ2=7.57,P<0.05). The average hospitals stays of the above two groups were 14.0 ± 3.5 d and 19.0 ± 6.8 d(t=2.85,P<0.01),respectively,and the average hospitalization expenses were(1.5 ± 0.5)thousand Yuan and(2.2 ± 0.7)thousand Yuan (t=24.57,P<0.01),respectively,both of the differences were statistically significant. On the 10th day after surgery,the mas-tery rates of the health knowledge of the two groups were 96.7%and 50.0%,respectively,the difference was statistically signifi-cant(χ2=16.86,P<0.001). Conclusions The implementation of the health education path can promote the rehabilitation of advanced schistosomiasis patients with splenomegaly,and increase the satisfaction as well as improve the mastery of the health knowledge of the patients. Meanwhile,it also can cut down the hospital stays and save the hospitalization expenses.
