BACKGROUND:There are various therapies for children limb fractures involving the epiphysis or the metaphysis. According to the different methods, studies on the growth of the epiphyseal plate are a lot, most of which focus on the effects of Kirschner wires with different diameters or holow screw internal fixation on the development of epiphyseal plate. However, there are rare studies on the influence of cross-epiphyseal plate internal fixation on the growth of epiphyseal plate as wel as the influence level. OBJECTIVE:To prepare a peri-epiphyseal fracture model in young rabbits and to observe the effects of cross-epiphyseal plate implantation and removal on the growth of epiphyseal plate. METHODS: Traverse fracture models were made 5 mm above the right femoral distal epiphyseal plate of 60 young rabbits, and then fixed with suitable “L” steel plate and four screws across the epiphyseal plate and peri-epiphyseal fracture line. The left side served as control. Eight rabbits were kiled and observed at 2, 4, 8, 12 weeks after modeling, respectively, to take out the femoral specimens for measurement of femoral length, thickness of the epiphyseal plate, and number of mastocytes per unit column. Histopathology observation was done and changes in mastocytes and thickness of the epiphyseal plate were detected. Another seven rabbits were selected to remove the metal plate, continued to feed for 2 weeks and finaly executed to observe the above-mentioned indexes. RESULTS AND CONCLUSION: (1) There were significant differences in the above indexes between the plate and control groups at 4, 8, 12 weeks after modeling (P < 0.05 orP< 0.001) but not at 2 weeks after modeling (P> 0.05). These findings indicate that within 2 weeks after cross-epiphyseal plate internal fixation, proper pressue has no remarkable influence on the growth of epiphyseal plate; but after persistent internal fixation (> 4 weeks), the growth of epiphyseal plate can be partialy or completed retarded. (2) At 2 and 4 weeks after modeling, the plate was removed, and 2 weeks later, the femoral length, thickness of the epiphyseal plate and mastocyte counting per unit column were improved to different extents, and there were no differences between the plate and control group (P > 0.05). At 8 and 12 weeks after modeling, the plate was removed, and 2 weeks later, the femoral length and thickness of the epiphyseal plate were shortened, and the number of mastocytes per unit column was decreased obviously, which significantly differed from the control group (P < 0.001). These findings indicate that the chondrocytes in the proliferative and hypertrophy layers lose the differentiation and proliferation abilities, and the femoral length and epiphyseal plate thickness are difficult to recover.

[ABSTRACT]OBJECTIVETo investigate the phoenix roebelenii pollen as the allergen of allergic rhinitis in Hainan Province and provide guidance for prevention and treatment of allergic rhinitits.METHODSA total of 2054 patients with allergic rhinitis were tested with the allergen of phoenix roebelenii pollen by skin prick test, and then choose 30 positive cases to give the nasal mucosa provocation test. RESULTSThe total positive rate of allergen of phoenix roebelenii pollen by skin prick test was 67.38% (1384/2054). The 30 cases with positive skin prick test were all positive in nasal mucosa provocation test and the cases in control group were all negative.CONCLUSIONPhoenix roebelenii pollen is an important allergen in Hainan Province. There is a correlation between skin prick test and nasal mucosa provocation test. The allergen skin prick test can provide clue for the patients to avoid the pathogenic allergens and for the specific immunotherapy.

Objective To investigate the role of UDP-glucuronosyltransferase 1A (UGT1A),nuclear factor erythroid-2-related factor 2 (Nrf2) and kelch-like ECH-associated protein 1 ( Keapl ) in the tumorigenesis of colonic carcinoma.Methods The expressions of UGT1 A,Nrf2 and Keapl were detected in normal colonic mucosa(24 cases),adenoma tissue (30 cases) and adenocarcinoma tissue (77 cases) by immunohistochemistry,and the relationship between their expressions and the clinical pathological characteristics was analyzed.Results The positive rates of UGT1 A in normal colonic mucosa,adenoma and adenocarcinoma tissue were 83.3％ ( 20/24),80.0％ ( 24/30 ) and 53.2％ ( 41/77 ),respectively.The positive rate of UGT1A in adenocarcinoma was lower than those in colonic mucosa and adenoma ( all P ＜0.05 ).On the contrary,the positive rates of Nrf2 in adenoma [70.0％ (21/30) ] and adenocarcinoma tissue [ 87.0％ (67/77) ] were higher than that in normal colonic tissue [ 41.7％ (10/24),all P =0.000 ].The positive rates of Keapl in normal colonic mucosa,adenoma and adenocarcinoma tissue were 54.2％ ( 13/24),70.0％ (21/30) and 61.0％ (47/77),respectively ( normal colonic tissue vs adenocarcinoma tissue,P =0.040 ; adenoma vs adenocarcinoma,P =0.002 ).There was no correlation between the expression of UGT1 A,Nrf2 and the clinicopathologic features of colon carcinoma,while the differences of Keapl positive rates in the various degrees of tumor differentiation [ moderately-well differentiated vs poorly differentiated:70.0％ (35/50) vs 44.4％ (12/27) ] and invasion [T1-T2 vs T3-T4:78.8％ (26/33) vs 47.7％ (21/44) ]were statistically significant (all P ＜ 0.05 ).Conclusion The decreased expression of UGT1A and the dysregulation of Nrf2/Keapl system may play a role in colonic tumorigenesis.

Objective To investigate the influence of the post stroke depression (PSD) on cognitive function in patients with stroke and their correlation, and to evaluate the diagnosis value of P300 cognitive function in patients with PSD. Methods One hundred and seventeen cases of inpatient with acute stroke in neurology medicine were continuously observed and scored using HAMD rating scale at the onset of 2 weeks. And 53 cases of PSD and 64 cases of non-post-stroke depression (NPSD) were scored using MMSE score and P300 determination respectively,and the results were compared. Results The incidence of PSD was 45.29%(53/117) at the 2 weeks after stroke,including 35 cases (29.91%) of mild depression,11 cases (9.40%) of medium degree depression and 7 cases (5.98%) of major depression. Compared with NPSD group, the P300 latency period of PSD group was significantly prolonged ( < 0.01), and the amplitude significantly reduced ( < 0.01) . The MMSE score difference was statistically significant ( <0.05) in the two groups. Conclusion The PSD is given priority to with mild-to-moderate depression, and the cognitive function damage in patients with PSD is more obvious than that in NPSD group. P300 determination can be used as the evaluation indicator of diagnosis cognitive function in patients with PSD.
