ABSTRACT
Plumage color is an important economic trait for breed feature identification and consumer's requirements in pigeons. The domestic pigeon has multiple types of plumage color, thereby providing a unique opportunity to identify the genetic basis of plumage coloration. White feather color is common for meat and medicinal use. To investigate the genetic variation associated with white plumage color in pigeons, we use genome resequencing and population genomics to identify the genomic regions with strong selective signature between pigeons with brown and white plumage color. Meanwhile, we obtained some candidate genes with melanin or melanosome biosynthesis in selected regions. Finally, we identified a missense mutation p.E256K in the EDNRB2 completely associated with white plumage color. These findings provide a basis for genetic variation in pigeons with plumage color phenotype.

ABSTRACT
Objective To evaluate the long-term results of minimal incision osteotomy for hallux valgus.Methods From February 1996 to May 1999,372 cases(705 feet)with hallux valgus were treated with minimal incision osteotomy.Seventy-nine cases after surgery were followed up for more than 5 years,including 6 males(10 feet)and 73 females(140 feet)with an average age of 47 years(range,13-75 years).The average follow-up time was 7.5 years(range,5.3-13.2 years).The preoperative and postoperative hallux valgus angles(HVA),intermetatarsal angles(IMA),the tibial sesamoid position(TSP),American orthopedic foot and ankle society(AOFAS)score,range of movement of the first metatarsophalangeal joint,and lateral metatarsalgia etc.were observed and measured.And the clinic outcome were studied and evaluated.Results Based on Wen Jian-min's clinic curative effect evaluation criterion(2001),56 feet(37.3%)were excellent,88 feet(58.7%)good ,6 feet(4.0%)fair.The rate of excellent or good was 96.0%(144/150).The postoperative mean AOFAS score was 84.20±4.32 points(range,60-100 points).The mean HVA decreased from 33.28 to 12.31 degrees,the mean IMA from 11.75 to 6.80 degrees.The TSP was corrected from an average preoperative grade of 4.29 to a grade of 3.07 at final follow-up.There are no nonunion or delayed union of osteotomy,avascular necrosis of the 1st metatarsal head,infection,hallux varus.Four feet(2.7%)had numbness in the medial of the big toe.The 1st metatarsophalangeal joint range of motion decreased from 70.20 to 69.53 degrees.There were 97 feet(64.7%)with the 2-5 metatarsalgia before operation,and 35 feet(23.3%)disappeared,54 feet(36.0%)improved,8 feet(5.3%)aggravated after operation.Conclusion Minimal incision osteotomy technique is sound and reliable method to treat hallux valgus.The osteotomy technique is simple,and could provide satisfactory long-term results with lower complication rate.
ABSTRACT
Objective To discuss the clinical effects of knee osteoarthritis treated with arthroscope and electro-acupuncture. Methods 57 patients (57 knee joints involved) , who were diagnosed by physical examinations and MRI as knee osteoarthritis, were treated by arthroscopy preoperatively and electro-acupuncture and rehabilitation training postoperatively. Results Among the total of 57 cases, 39 cases were recovery (68%), 17 cases were improved (30%), l case was ineffective (2%). The score of preoperative and postoperative HSS assessment was ( 50.3 ± 5.42 )and ( 59.2± 5.28 )respectively (P < 0.05 ). Conclusion The treatment of knee osteoarthritis with arthroscope and electro-acupuncture is effective.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy and feasibility of the Chinese drugs for supplementing Qi and activating blood circulation in preventing DVT after big operations in orthopaedics and traumatology and observe the change of D-dimer before and after treatment.</p><p><b>METHOD</b>Seventy patients ranging in age from 39 to 94 years who were treated by big operations in orthopaedics and traumatology were divided into two groups randomly. Traditional Chinese medinine (TCM) group (group A) and western medicine group (group B). On the 2rd day after operation d-dimer was tested from both groups and the patients in group A were given one dose of TCM every day and the patients in group B were subcutaneously injected low-molecular-weight heparins calcium (LMWH). On the 8th after operation d-dimer was tested again from both groups. The parameters, such as the incidence of DVT and pulmonary thromboembolism, bleeding condition, were evaluated respectively.</p><p><b>RESULT</b>The D-dimer decreased in group A and had significant difference (P < 0.05), group B had no significant difference, there was also no significant difference between two groups. DVT was found in 1 patient in group B (1/35). Petechiae were found in 10 patients in group A (10/35) and in 26 patients in group A (26/35), which had significant difference (P < 0.05).</p><p><b>CONCLUSION</b>Both the Chinese drugs and anti-coagulation drug can prevent the incidence of DVT effectively, and Chinese herbs are feasible in the prevention of DVT.</p>

Objective To study the relation between the pressure in forefoot and the second metatarsalgia in hallux valgus deformity, finally to quantitatively analyze the pressure under the second metatarsal head which is a dangerous factor leading to second metatarsalgia. Methods Three groups volunteered for this study by a self-devised foot pressure measurement system: fifty-eight normal subjects (116 feet) without pain and deformity in foot, thirty-two patients (45 feet) with hallux valgus and pain only under the second metatarsal head, fifty-six patients (102 feet) with hallux valgus without symptoms of metatarsalgia. The percentage of pressure to weight was the criteria for data analysis. First the pressures under second metatarsal head among three groups were compared with each other. Secondly we used case-control study to identify whether it was high pressure that was likely to result in metatarsalgia. Finally we compared the pressure interval under second metatarsal head among three groups to define the pressure interval which might be a dangerous factor to second metatarsalgia. Results 1)The pressure beneath the second meatatarsal head in patients with metatarsalgia was the highest in the three groups (P
