Objective To explore the methods and clinical results of the arthroscopic acromioplasty for the treatment of impingement syndrome of shoulder. Methods 15 cases with impingement syndrome of shoulder were studied. There were 9 males and 6 females. 10 right shoulders and 5 left ones were involved. The average age of patients was 47 years ranging from 32 to 54 years. 3 injuries were classified as degree I, 4 as Ⅱ, and 8 as Ⅲ according to Neer classification. All the patients had a chronic injury and painful history around shoulder. The positive arch pain test was presented in 12 cases and impingement test in 13 cases. 13 patients had been received MR examinations, and 5 arthrographies of the shoulder. The AP and the supraspinatus outlet projection of the X-rays were obtained before surgery. The procedure of arthroscopic acromioplasty consisted of 5 following steps: the first was arthroscopic subacromial inspection with posterior portal; the second was subacromial bursectomy with electro-shaver or burr; the third was release or resection of the coracoacromial ligament with electrocautery; the fourth was subacromial decompression with full-radius resector or burr; and the last was debridement of the soft tissue around the acromio-clavicular joint and resection of the the spurs. 4 patients underwent reparation of the rotator cuff simultaneously. Results All cases were available for follow-up. The average time was 15 months. According to the UCLA scoring system, the average score was 18.5?8.2 and 31.7?6.5 pre- and post-operation respectively; the difference was of statistical significance(t=3.35, P

Objective:
To understand the situation of mosquito larva breeding and adult mosquito density among schools in Yangpu District, Shanghai Municipality before the start of the fall semester, so as to provide insights into mosquito prevention and control in schools.
Methods:
A stratified sampling method was used to select four schools each from universities, primary and secondary schools, and preschool institutions as survey sites. A survey of mosquito larva breeding sites and adult mosquito density was carried out in August each year from 2021 to 2023. The mosquito larva breeding sites in small and large water bodies were investigated by visual inspection and spoon trapping methods, and adult mosquito density was investigated by human-induced stinging method. The positive rate of mosquito larva breeding sites and adult mosquito landing index were analyzed.
Results:
Totally 1 253 mosquito larva breeding sites were investigated from 2021 to 2023, and the positive rate was 4.07% (51 positive sites). The positive rates of mosquito larva breeding sites in universities, primary and secondary schools and preschool institutions were 2.36%, 4.05% and 8.30%, respectively. The top three positive breeding sites in small water bodies were tyres (6.67%), small stagnant water in green belts (6.04%) and unused containers (5.92%), and Aedes albopictus was the dominant species (97.21%). The top three positive breeding sites in large water bodies were rainwater wells (3.90%), landscape water bodies (3.45%) and sewage wells (3.23%), and Culex pipiens pallens and Aedes albopictus each accounted for 50.00%. A total of 200 adult mosquitoes were captured from 2021 to 2023, with Aedes albopictus being dominant (93.00%). The total landing index decreased and then rebounded slightly from 2021 to 2023, with the highest seen in 2021 as 1.78 mosquitoes/0.5 hours per person. The highest mean adult mosquito landing index was 1.17 mosquitoes/0.5 hours per person in preschool institutions.
Conclusions
The positive rates of mosquito larva breeding sites and landing index of adult mosquitoes among schools in Yangpu District before the start of the fall semester from 2021 to 2023 were higher than the relevant provisions of the Shanghai municipal local standards. Aedes albopictus was the dominant species. Mosquito surveillance in schools should be carried out on a regular basis and hygiene management should be strengthened.

Purpose: To apply staged arteriovenous reversal in the treatment of extensive and diffuse arterial occlusive disease of the limb. To avoid amputation of the limb or to limit it to necrosed segments.
Methods: Exactly 138 patients (a total of 153 severely ischemic limbs) were applied staged arteriovenous reversal (AVR) from January 1984 to December 1995. Generic-specific involvement totaled 106 men and 32 women. Their ages ranged from 24 to 71, averaging 48.7 years. The duration of symptoms ranged from 15 days to 17 years. A total of 112 patients were diagnosed as having Buerger's disease, and 25 had arteriosclerosis. In one patient, the popliteal artery was completely obstructed by acute emboli of atheromatous plaques. Three patients with Buerger's disease had not benefited from lumbar sympathectomy or partial adrenalectomy done several years ago. According to different levels of extensive and diffuse arterial occlusion, arteriovenous reversal was formed at three different sites: (1) high-deep reversal, produced between the external iliac, common femoral, or superficial femoral artery and the superficial femoral vein; (2) low-deep reversal between the distal popliteal artery and tibioperoneal venous trunk; (3) superficial reversal, established between the distal popliteal artery and distal portion of the long saphenous vein.
Results: Until June 1996, a total of 132 patients were followed up for 0.5-12 years, averaging 6.5 years. The postoperative results of all limbs except 12 in this series are excellent or good. Cardiac dysfunction does not occur, nor does the marked elevation of venous pressure of the limb.
Conclusion: We consider that if the deep venous trunks are patent, the limbs with extensive arterial occlusion are indicated for staged AVR if severe ischemia is present and all other therapeutic methods have failed. Even with necrotic limbs, this operation may lower the level of amputation. The authors suggest that staged arteriovenous reversal is a new and effective approach in the treatment of extensive arterial occlusive disease of the limb.
