China Medical Equipment 2015;(6):94-96,97
Objective: To observe the efficiency of the therapy of hormone treatment aftertranscerviacal resection of endometrial polyps (TCRP). Methods: Eighty-six cases of endometrial polyps were analyzed retrospectively. They were divided into the control group (39 cases), which with simple TCRP, and the observation group (47 cases), which treated with hormone after TCRP. The clinical efficiency was compared between 2 groups. Results:The operation time of control group is 16-45 min, average (29.8±7.2) min; the intraoperative blood loss was 10-65ml, average(41.8±11.6) ml. The operation time of observation group was 18–55 min, average (33.2±8.8) min;the intraoperative blood loss was from 13–69 ml, average(43.2±13.1)ml. The differences of operation time and intraoperative blood loss between the two groups were not significant. The recurrence rate of observation group (6.38%) was much lower than control group(30.77%)(x2=8.802, P<0.05). 1 month, 3 months, 6 month and 1 year after therapy, the menstrual blood volume were (53.6±17.8)ml, (41.3±13.5)ml, (33.8±9.6)ml and (20.8±6.4)ml, respectively, which were much lower than the control group (t=12.564, t=12.691, t=14.494, t=23.72; P<0.05). 1 month, 3 months, 6 month and 1 year after therapy, the endometrial thickness were (8.2±1.0)mm, (7.1±0.9)mm, (4.2±0.8)mm and (3.5±0.7)mm, respectively, which were much lower than the control group (t=1.324, t=3.774, t=11.996, t=10.508; P<0.05). Conclusion: The menstrual blood volume, the endometrial thickness and the recurrence of endometrial polyps can be effectively reduced with the hormone therapy after TCRP.

4.MORpHOLOGY AND SPROUTING OF MOTOR NERVE TERMINALS IN CAT: DIFFERENCES BETWEEN FAST AND SLOW MUSCLES
Acta Anatomica Sinica 1955;0(03):-
Motor nerve terminals of fast muscles (lateral head of gastrocnemius, l. g. medial head of gastrocnemius, m. g.) and slow muscles (soleus, sol.) in 4 healthy adult cats were studied in teased muscle fibres with zinc iodide-osmium tetroxide (ZIO) staining. The motor nerve terminals stained with ZIO had a more delicate appearnance than those stained with other methods. It was obvious that fairly marked differences between the strutures of fast and slow muscle end-plate in cat. The terminal sprouts were also different between fast and slow muscle motor nerve terminals. in cat. The percentages of preterminal sprout were mean%?S.D. 8.5?5.4, 7.1?3.2 and 0.3?0.5 in l. g., m. g, and sol. respectively, and the percentages of ultraterminal sprout were 0, 0.3?0.5 and 5.7?2.0 in l. g., m. g. and sol. respectively. In each l. g., m. g. or sol. muscle, not only the size and complexity of end-plates were different, but also there were various kinds of end-plates. All of these showed the different stages of growth, sprouting, degeneration and replacement. The turnover of motor nerve terminal and the factors which influence the morphology of the end-plates in normal adult cat are discussed.
7. Protective effects of 3, 4-di-O-methyl-1,2,5,6-D-Mannitol tetranitrate on myocardial ischemia induced by ligating coronary artery in rats
Chinese Pharmaceutical Journal 2012;47(3):190-193
OBJECTIVE: To study the effects of 3, 4-di-O-methyl-1, 2, 5, 6-D-mannitol tetranitrate(DMMTN) on acute myocardial ischemia induced by ligating coronary artery in rats. METHODS: Acute myocardial ischemia model was developed by ligating the anterior descending branch of left coronary artery in rats. The rats were randomly divided into 6 groups: sham group, model group, Lunanxinkang group, low-dose (15 mg · kg-1) DMMTN group, middle-dose (30 mg · kg-1) DMMTN group and high-dose (60 mg · kg-1) DMMTN group. The changes of ST segment and T segment of electrocardiogram at different moment were recorded after myocardial ischemia injury. At 3 h after ligation, the myocardial infarct size was measured by nitroblue tetrazolium (NBT) staining method. And the activities of creatine phosphokinase (CK), lactate dehydrogenase (LDH) and superoxide dismutase (SOD), and the content of malondialdehyde (MDA) were determined to evaluate the protective effects of DMMTN. RESULTS: DMMTN could reduce the size of myocardial infarct significantly, inhibit the rising of ST segment and T segment of electrocardiogram, decrease the level of CK, LDH and MDA, and increase the activity of SOD. CONCLUSION: DMMTN showed obvious protective effects on acute myocardial ischemia induced by ligating the coronary artery in rats. Copyright 2012 by the Chinese Pharmaceutical Association.

Objective: To evaluate the role of the deep radioulnar ligament in the stability of the distal radioulnar joint (DRUJ).Methods: In the study, 14 fresh cadaver upper extremities were randomly divided into two groups.After exposuring the palmar and dorsal deep distal radioulnar ligament, one group was marked as palmar deep radioulnar ligament, and the other group was marked as dorsal deep radioulnar ligament.The pronator teres and the supinator were exposed.A Kirschner wire perpendicular to the bone on Lister tubercle of radius was inserted, then another Kirschner wire on the same level of ulnar inserted when the forearm was in neural position, which was kept parallel to the first Kirschner wire.These specimens were mounted on a specially designed jig which held the limb rigidly, keeping the elbow fle-xion and the ulnar fixation.The radius could freely rotate around the ulnar.Then 50 N force on the pronator teres was applied to simulate the active pronation, and 60 N force on the supinator to simulate the active supination.The active pronation was stimulated, and the displacement of the distal radius was measured with respect to the ulna.The active supination was atimulated, and the displacement of the distal radius was measured with respect to the ulna.The palmar deep radioulnar ligament in one group was cut, then the displacement of the distal radius measured with respect to the ulna when the forearm was in pronation and supination.The dorsal deep radioulnar ligament in the other group was cut, and the displacement of the distal radius measured with respect to the ulna when the forearm was in pronation and supination.Results: After resection of the palmar deep radioulnar ligament, the displacement of the distal radius with respect to the ulna was statistically significantly different when the forearm was in pronation (t=5.591, P=0.001), but there was no difference when the forearm was in supination (t=0.433, P=0.680).After resection of the dorsal deep radioulnar ligament, the displacement of the distal radius with respect to the ulna was not different when the forearm was in pronation (t=1.000, P=0.356), but there was statistically significant difference when the forearm was in supination (t=6.225, P=0.001).Conclusion: DRUJ is unstable when the forearm is in pronation after resection of the palmar deep ra-dioulnar ligament, and DRUJ is unstable when the forearm is in supination after resection of the dorsal deep radioulnar ligament.
