Objective:To explore the clinical application of distal and proximal bilateral lateral pre-decompression in replant of digit degloving injury.Methods:From March 2012 to May 2021, 14 patients with 29 digits had replantation surgery of degloved soft tissue and severed digits in Section II, Department of Orthopaedics, Changzhou Medical District of 904th Hospital of PLA Joint Logistic Support Force. There were 2 types of injuries: degloving injury of soft tissue but with intact digital tip, and digital tip degloving injury with intact distal phalanx and nail bed. With the technique of distal and proximal bilateral lateral pre-decompression, pre-decompression incisions were made to the subdermal on both sides of the degloved skin over the proper palmar digital arteries. From where, the distal stump of the proper palmar digital arteries and nerves for anastomosis were found and had them anastomosed with the proximal proper palmar digital arteries and proper palmar digital nerves, then anastomosed digital pulp and digital dorsal veins (11 cases were direct anastomosis and 3 cases were bridged anastomosis). Follow-up was carried out by outpatient consultation, telephone and WeChat APP. The appearance of the digit body, the shape of digital pulp, the nails grow and the motions of the digits were observed, and the Evaluation Standard of Replantation of Severed Fingers by the Society of Hand surgery of Chinese Medical Association was used to evaluate the recovery of function.Results:All 29 segments of degloving digit survived. Small necrotic areas was found in 4 digits and healed after the change of dressing. The followed-up time was lasted for 3-36 months. There was no obvious atrophy found in all the digits. Appearances of digit pulp and nails were satisfactory with good sensational recovery for TPD at 6-10 mm, 7 mm in average. Motions of all the repaired digits were good. According to the Evaluation Standard of Replantation of Severed Fingers by the Society of Hand surgery of Chinese Medical Association, 23 digits were in excellent, 4 in good and 2 in poor, with a satisfactory rate at 93.1%.Conclusion:For a distal digit injury with intact distal soft tissue and relatively mild injury of blood vessels and nerves, using the method of distal and proximal bilateral lateral pre-decompression can help to achieve good appearance in survived digital pulp, good sensational recovery and good nail growth. An individualised treatment intra-and-after the surgery could offer an ideal therapeutic effect.

OBJECTIVETo study the changes of dietary pattern among adult residents in different areas of Liaoning province from 1989 to 2006.
METHODSHealthy adults (6213 subjects) at age of 18 - 65 years from 480 households in three cities (Shenyang, Yingkou, Wafangdian) and three counties (Qingyuan, Huanren, Chaoyang) were selected with stratified multiple cluster random sampling. The information on nutrient intake of the subjects were collected from datasets of Chinese Health and Nutrition Survey conducted in 1989, 1991, 1993, 2000, 2004, and 2006. Different food intake, the nutrients intake percentages for recommended nutrition intake (RNI) and appropriate intake (AI), and the percentages of total energy and protein from grain, animal product, bean and its product were calculated to assess the residents' dietary pattern and nutrition status. The changes of dietary pattern among adult residents were analyzed.
RESULTSAmong the residents, there were a 38.1% of decreased intake for grain (from 601.9 to 372.5 g/d), 20.5% for potato (from 75.6 to 60.1 g/d), 25.1% for beans (from 38.7 to 29.0 g/d), and a 77.2% of increased intake for fish and shrimp (from 25.0 to 44.3 g/d), 36.9% for livestock and poultry (from 65.6 to 89.8 g/d), 47.7% for fruit (from 70.7 to 104.4 g/d), and intake of milk product (from 5.8 to 21.3 g/d), egg (from 17.3 to 35.7 g/d), vegetable (from 296.1 to 316.3 g/d) were also increased from 1989 to 2006. During the period, the intake percentages of energy and protein from grain decreased from 67.5% (8.7 MJ/12.8 MJ per day) to 51.5% (5.0 MJ/9.6 MJ per day) and from 72.0% (66.2 g/91.9 g per day) to 59.7% (45.3 g/75.9 g per day), and on the contrary those from animal products increased from 8.9% (1.1 MJ/12.8 MJ per day) to 14.8 (1.4 MJ/9.6 MJ per day) and from 15.9% (14.6 g/91.9 g per day) to 27.9% (21.2 g/75.9 g per day), respectively. In 2006, the intake of vitamin A (508.9 µg/d) was 67.6% of it's RNI, intake of vitamin B(2) (0.9 mg/d) was 64.6% and the intake of calcium (453.7 mg/d) was 52.5% of it's AI among the residents.
CONCLUSIONThe intake of plant food decreased and that of animal food increased from 1989 to 2006 and the dietary intakes of calcium, vitamin A, vitamin B(2) need to be increased among adult population of Liaoning province.
