Han Jiangbo. Department of Theoretical Mechanics, Luoyang Industry College. Luoyang Since January 1982 we have relocated the insertion of a part of pectoralis major or deltoid muscle in the treatment of 5 cases of habitual dislocation of shoulder. After over a year of follow-up no recurrence of dislocation has been found in all the cases. The shoulder joint seemed to be stable, the range of movements increased, and disturbance in supination was corrected. The operative procedure was studied in fresh cadavers and human skeleton. Studies on mechanical model of shoulder joint, with theoretical calculation of changes in pronation after muscle displacement, showed that movements of pronation were remarkably increased after displacement of partial pectoralis major and deltoideus. It could also compensate the weatened subscapularis.

Objective:
To explore the impact of five-flavor Sophora flavescens enteric-coated capsules (FSEC) on the intestinal flora of rats with ulcerative colitis (UC), so as to provide the reference for the mechanism of FSEC in treating UC.
Methods:
Forty SPF-grade Wistar rats were randomly divided into the control group, the model group, the mesalazine group and the FSEC group. Except the control group (0.9% sodium chloride solution), the other 3 groups used 3% dextran sulfate sodium (DSS) for 7 days to establish UC model. After successful modeling, the control group and the model group were given 2 mL/kgbw of 0.9% sodium chloride solution by gavage for 2 weeks, while the mesalazine group and the FSEC group were given 2 mL/kgbw of mesalazine suspension (0.2 g/kg) and FSEC granule suspension (2.16 g/kg), respectively. Pathological changes of colon tissue were observed after hematoxylin-eosin (HE) staining. Rat fecal samples were collected, and 16S rDNA high-throughput sequencing and bioinformatics analysis were performed on intestinal flora. The α and β diversity of intestinal flora among the four groups were compared, and the dominant flora was screened using LEfSe analysis.
Results:
Compared with the control group, the model group showed a significant loss of colonic crypts and a large infiltration of inflammatory cells. Compared with the model group, the mesalazine group and the FSEC group exhibited a slight loss of colonic crypts, a small amount or an absence inflammatory cell infiltration, and improved tissue damage. The α-diversity analysis showed that compared with the control group, the Chao1 and Shannon indices in the model group increased, while the Simpson index decreased; compared with the model group, the Chao1 and Shannon indices in the mesalazine group and the FSEC group decreased, and the Simpson index increased(all P<0.05). The β-diversity analysis showed that the sample distance between the FSEC group and the control group were more closer than that between the model group and the control group. LEfSe analysis results showed that the dominant bacteria in the model group were mainly from the Alistipes and Oscillospira. In the FSEC group, the dominant bacteria were from the Ruminococcus and Prevotella.
Conclusion
FSEC can improve the structures of intestinal flora, increase the abundance of beneficial bacteria such as Ruminococcus and Prevotella, reduce the abundance of pathogenic bacteria such as Alistipes, and alleviate the inflammatory response in UC rats.

OBJECTIVE:
To discuss the role of forehead flap in large external nasal defect reconstruction.
METHOD:
We retrospectively reviewed the clinical and follow-up data of 11 patients with large or full-thickness external nasal defects, which were reconstructed with single-or two-stage interpolated or island forehead flaps from January 2007 to June 2011. All patients were male,defects of 9 cases were resulted from resection of skin malignant tumor and traumatic defect in 2 cases. The average diameter of defects was 3.3 cm (2.5-5.0 cm). Four cases had alar full thickness defect. The supratrochlear and angular artery of the elders (>70 yrs) and patients with suspicious peripheral blood vessel lesions were scanned before the surgery by Doppler ultrasonic. The defects were reconstructed by two-stage interpolated flap in 7 cases; five cases were reconstructed by single-stage island flap technique. A nasolabial flap based on piriform aperture was turned into the nasal cavity to reconstruct the lining.
RESULT:
All defects were repaired successfully. All tissue flap survived and the scar was not conspicuous. One patient had nostril stenosis with mild nasal congestion complain at the 6th postoperative month.
CONCLUSION
The forehead flap, interpolated or island, can be used safely and effectively to repair the large external nasal defect in experienced hands.

Dirofilaria immitis (heartworm) infections affect domestic dogs, cats, and various wild mammals with increasing incidence in temperate and tropical areas. More sensitive antibody detection methodologies are required to diagnose asymptomatic dirofilariasis with low worm burdens. Applying current transcriptomic technologies would be useful to discover potential diagnostic markers for D. immitis infection. A filarial homologue of the mammalian translationally controlled tumor protein (TCTP) was initially identified by screening the assembled transcriptome of D. immitis (DiTCTP). A BLAST analysis suggested that the DiTCTP gene shared the highest similarity with TCTP from Loa loa at protein level (97%). A histidine-tagged recombinant DiTCTP protein (rDiTCTP) of 40 kDa expressed in Escherichia coli BL21 (DE3) showed immunoreactivity with serum from a dog experimentally infected with heartworms. Localization studies illustrated the ubiquitous presence of rDiTCTP protein in the lateral hypodermal chords, dorsal hypodermal chord, muscle, intestine, and uterus in female adult worms. Further studies on D. immitis-derived TCTP are warranted to assess whether this filarial protein could be used for a diagnostic purpose.
