Objective Establish and evaluate the method of number of alleles identical by state in full sib test.Methods Sib pair group and unrelated individual pair group were genotyped in 13 STR loci,statistical calculation was carried out.Results Through analysis by discriminant function the posterior probability of membership in each group and error of the posterior probability was obtained.The discriminant function in sib group is L sib =-27.087 03+3.202 32S(S:number of alleles identical by state);The discriminant function in unrelated individual group is:L unrelated =-7.495 63+1.685 09S.The average error of the posterior probability in sib and unrelated pair group is 0.026 5.Conclusion When the number of alleles identical by state is more than 17 or less than 8,posterior probability of a full sib or unrelated individuals is more than 0.998 0 or 0.999 4,respectively.The method based on the number of alleles identical by state in full sib test is credible in identifying sib pair relationship.

Objective To study the prognostic value of modified early warning score (MEWS) and Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) score in emergency ICU elderly patients.Methods 113 elderly patients were collected in emergency ICU,after admission to calculate the MEWS score and APACHE Ⅱ score,the MEWS score and APACHE Ⅱ score difference were compared between death group and survival group.the differences were compared in MEWS score ≤ 3,4 ～6,7 ～ 9,≥ 10 scores groups respectively;analysis of the MEWS score and APACHE Ⅱ the relevance score.the correlation analysis of the MEWS score and APACHE Ⅱ score was given.Results The MEWS(7.91 ± 2.42) point and APACHE Ⅱ (21.9 ± 4.18) point in death group were greater than that in survival group [(4.51 ± 2.14) point,(19.53 ± 4.37) point] (t =7.49,2.70,all P ＜ 0.01).With MEWS score increasing,the fatality rate rose(P ＜0.01).the MEWS score and APACHE Ⅱ score was correlated(r =0.617,P ＜ 0.01).Conclusion The MEWS score was a simple and quick scoring system,as well as APACHE Ⅱ,it can predict the prognosis of elderly patients in emergency department,it has important application value.

Objective To investigate changes in lengths of the wrist ligaments during wrist radioulnar deviation. Methods Six volunteers were included in the study. CT scans was used to detect the changes under different positions of the wrist in the volunteers. The wrists were scanned from the position of radial deviation of 20° to the one of ulnar deviation of 40° at an interval of 20°. The 3-dimensional carpal and distal radioulnar joint structures were reconstructed with customized software and chauges in length of the palmar and dorsal wrist ligaments in radioulnar deviation were computed. Results From wrist radial deviation to neutral position, the lengths of the radioscaphocapitate ligament, the long radiolunate ligament and the dorsal intercarpal ligament increased significantly (P ＜ 0.05), they increased (2.4±0.3) mm, (2.3±0.8) mm,(1.2±0.6) mm, (1.2±1.2)mm and (2.6±1.0) mm respectively. While from wrist ulnar deviation to neutral position, ulnocapitate ligament and the dorsal radiocarpal ligament increased significantly (P ＜ 0.05), they increased (0.8 ±0.6) nm and (1.0±0.5) mm respectively. Conclusion At wrist radial deviation, the radioscaphocapitate, long radiolunate and dorsal intercarpal ligaments are slack. At wrist ulnar deviation, the ulnocapitate ligament and the dorsal radiocarpal ligament are slack. These positions may be favorable to healing of these ligaments.

BACKGROUND:There is little evidence on the use of al ogeneic tendon graft in the reconstruction of ankle joint.
OBJECTIVE:To explore the clinical outcome of anatomical reconstruction of the lateral ligaments with cryopreserved al ogeneic tendon graft in patients with chronic ankle instability.
METHODS:Twenty-six patients with chronic lateral instability underwent anatomical reconstruction of the lateral ligaments with cryopreserved al ogeneic tendon. There were 18 cases of simultaneous injury or chalasia in calcaneofibular ligament and anterior talofibular ligament, and 8 cases of anterior talofibular ligament injury or chalasia. The ankle joint function was evaluated according to AOFAS scale and Good classification. The affect ankle and healthy ankle were compared in the extension, plantar flexion activity, and metaleg activity.
RESULTS AND CONCLUSION:Al the 26 patients were fol owed up for 9-24 months with a mean of 15 months. No cases appeared recurrent ankle lateral instability. The mean AOFAS score in the group of calcaneofibular ligament and anterior talofibular ligament was improved from (48.4±3.7) points preoperatively to (88.2±3.8) postoperatively, while that in the group of anterior talofibular ligament was improved from (50.0±6.4) points preoperatively to (89.5±3.4) points postoperatively. According to Good score, there were excellent in 19 feet, good in 6 feet, fair in 1 foot, with an excellent and good rate up to 96%. No serious complication was occurred in this group. Anatomical reconstruction of the lateral ligaments with cryopreserved al ogeneic tendon graft can increase the tendon-bone contact area, improve the rate of tendon healing, and enhance the stability of ankle joint in patients with chronic ankle instability. Further studies are needed to verify its long-term efficacy.

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.
