ABSTRACT
For the purpose of preventing and treating the injuries in female football players, we investigated the incidence and the types of injuries, and analyzed the causes that lead to the injuries in 175 players from 8 female football teams. The results were as follows: (1) The incidence of injuries was 235.4 ％, including 41.8 ％ of acute and 58.2 ％ of chronic injuries. (2) The main injures included contusion (46.5 ％), sprain (22.8 ％), muscle torsion (11.5 ％), and abrasion (10.9 ％). (3) The injuries usually occurred in ankle (22％), knee (14.8 ％), thigh (14 ％), head and neck (9.5 ％), leg (8.5 ％), foot (7.4 ％), lumbar (6.6 ％). (4) The major causes of injuries included: inadequate training (33.3 ％), disobeying training principles (25.2 ％), man-made factors (24.2 ％),and others (17.5 ％). In accordance with the causes, 93 players from Guangdong, Henan, Shandong, Bayi female football teams in 1997 were taken as the treatment group with various prevention and treatment measures, while 58 players from Beijing, Hebei, Shanxi female football teams were taken as the control group. The incidence of injury in 1998 was 105.4 ％ in the treatment group, while 229.3 ％ in the control group (P<0.05). As compared with the incidence of injury in 1997 (235.4 ％), the incidence of injury in the treatment group was also statistically lower (P<0.05). It was concluded that the measures of prevention and treatment in the study were effective.
ABSTRACT
AIM:To determine the effects of different-term streptozotocin(STZ)-induced diabetes on ischemia/reperfusion(I/R)injury and cell apoptosis in rats myocardial via alterations in myocardial peroxynitrite.METHODS:The models of I/R injury were induced by occlusion and reperfusion of the left descending coronary artery(LDCA)in rats.I/R-induced infarct size was determined using triphenyltetrazolium chloride(TTC)staining.Quantified caspase-3 expression was used to represent apoptosis by Western blotting analysis.Peroxynitrite formation as indicated by nitrotyrosine level was measured by morphometric analysis.RESULTS:Two weeks after STZ treatment,infarct size(35.00%?3.00%)was smaller in 2 weeks diabetic hearts(2WKD)as compared with time-matched control group(2WKC)(51.00%?3.30%),whereas after 16 weeks of diabetes(16WKD),the infarct size(61.00%?3.00%)was bigger in the diabetic hearts as compared with the 16WKC group(50.00%?2.00%,P
