Objective To study and analyze the features and pattern of the common diseases occurred among recruits of a certain naval unit during training,so as to provide reference for the prevention of diseases.Methods Medical data files in the medical corps were sorted out,and were then classified according to the types of diseases,and finally were analyzed statistically.Results During recruit training,through outpatient service,inpatient service and medical tours or calls,there were 362 cases of various diseases,accounting for 22.3％ of all the recruits engaged in the recruit training.The top three diseases were:infection of the upper respiratory tract,with 128 cases,accounting for 7.88％,soft tissue injury of extremities with 68 cases,accounting for 4.18％ and oral diseases with 22 cases,accounting for 1.35％.From the perspective of diseases incidence,the top 3 disease respectively accounted for 35.4％,18.8％ and 6.1％,with a total incidence of 60.3％ of all the diseases.Conclusions Closer attention to the weak links in disease prevention and better prevention and treatment measures against the common disease among the recruits were the surest guarantee for the reduction of incidence and improvement of training results.

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.

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.
