0.05). There were 7 cased in the polypropylene mesh group had abdominal discomfort due to stiffness, which higher than that of the expanded polytetrafluroethylene patch and control groups (P 0.05). CONCLUSION: Both prosthetic patches are safe and effective when used in the repair of inguinal hernia in aged patients with low recurrence rate, especially, the expanded polytetrafluroethylene patch, which is more comfortable than polypropylene mesh.

Journal of Applied Clinical Pediatrics 1993;0(03):-
Objective To investigate the effects of extractum trametes robiniphila murr combinated with hydroxyurea on proliferation and apoptosis of K562 cells and whether the 2 drugs have synergistic effects,and to detect the antiproliferation and apoptosis ratio of cells in diffe-rent groups were detected.Methods K562 cells were cultured in vitro,and logarithmic phase cells were used for study.MTT-inhibitory test and cell morphological analysis were employed to examine the effects of extractum trametes robiniphila murr alone or in combination with hydroxyurea on proliferation of K562 cells.The effects of extractum trametes robiniphila murr alone or in combinated with hydroxyurea on apoptosis of K562 cells were examined by flow cytometry.The expressions of bcr-abl,bax and bcl-xl mRNA levels were detected by way of reverse transcription polymerase chain reaction(RT-PCR).Results Extractum trametes robiniphila murr could inhibit proliferation and induce apoptosis of K562 cells,and extractum trametes robiniphila murr combinated with hydroxyurea had a synergistic effects on cell prolife-ration and apoptosis.The RT-PCR displayed that either extractum trametes robiniphila murr alone or in combinated with hydroxyurea could down-regulate the expression of bcl-xl mRNA and up-regulate the expression of bax mRNA and the effect of the 2 drugs had a synergistic effect on bcl-xl and bax mRNA expressions.Extractum trametes robiniphila murr alone could also down-regulate the expression of bcr-abl mRNA,but hydroxyurea alone did not show any effect on the expression of bcr-abl mRNA and the 2 drugs had no synergistic effect.Conclusions The effect of extractum trametes robiniphila murr combinated with hydroxyurea on the proliferation and apoptosis of K562 cells has a synergistic effect.The mechanism of antiproliferation and inducing apoptosis of extractum trametes robiniphila murr is probably related to down-regulating the expression of bcl-xl and bcr-abl mRNA and up-regulating the expression of bax mRNA.The synergistic effect of antiproliferation and inducing apoptosis of extractum trametes robiniphila murr combinated with hydroxyurea on K562 cells is probably related to down-regulating the expression of bcl-xl mRNA and up-regulating the expression of bax mRNA.

ObjectiveTo examine the attachment style,the anxious and avoidant related attachment in adolescent patients with somatoform disorders.MethodsAll of the 66 patients who were diagnosed as somatoform disorder and 80 controls completed the assessments of common information,experiences in close relationships scales.All the data was analyzed by SPSS13.0.ResultsCompared with control group,somatofonn disorder group had higher ratio of insecure attachment,and there were statistically significant differences between them (29.5%vs 81%,x2 =40.584,P<0.01 ).The scores of avoidant and anxious related attachment in somatoform group were significant higher than those in control group ( separately 70.51 ± 15.08 vs 62.58 ± 14.18,t =4.449,P <0.0l ;64.25 ± 18.91 vs 51.49 ± 14.13,t =3.210,P < 0.01 ).ConclusionThere is a higher incidence of insecure attachment and higher level of anxious and avoidant related attachment in adolescent patients with somatoform disorder.The most common style is dismissing attachment.

Objective To investigate the changes in trafficking of GluRl-containing AMPA (GluR1-AMPA) receptor and GluR2-AMPA receptor from cytoplasm to cell membrane in the spinal cord dorsal horn in a rat model of incisional pain.Methods Thirty-two adult male SD rats aged 6-8 weeks weighing 280-300 g were randomly divided into 2 groups:control group (group C,n =8) and incisional pain group (group Ⅰ,n =24).An 1 cm long incision was made in the plautar surface of right hindpaw according to Brennan et al.in group Ⅰ.Cumulative pain score (CPS) and paw-withdrawal threshold to yon Frey stimuli (PWT) were measured at 3 h and day 1 and 3 afar incision ( T1,2,3 ).The animals were sacrificed after pain behavior assessment.Their lumbar segments of the spinal cord (L3-6) were removed.The expression of GluR1 and GluR2 in cell membrane and cytoplasm in spinal cord dorsal horn was determined by Western blot analysis.The co-expression of Stargazing with GluR1 and GluR2 in the spinal cord dorsal horn was examined by co-immuno-precipitation.Results The CPS was increased and PWT decreased; the GluR1 expression in cytoplasm was decreased while the expression of GluR1 in cell membrane and the co-expression of Stargazing with GluR1 were up-regulated in group Ⅰ as compared with group C.There was no significant change in the expression of GluR2 in cytoplasm and cell membrane and the co-expression of Stargazing with GluR2 in group Ⅰ as compared with group C.Conclusion GluR1-AMPA receptor transfers from cytoplasm to cell membrane but GluR2-AMPA receptor does not in rats with incisional pain.

Objective To evaluate the mitochondrial function of chondrocytes in Kashin-Beck disease (KBD) patients and its correlation with age.Methods Mitochondrial function was evaluated by analyzing the activities of respiratory chain enzyme complexes and citrate synthase (CS),intracellular adenosine triphosphate (ATP)contents, changes in mitochondrial membrane potential (ΔΨm),as well as the intracellular reactive oxygen species (ROS) contents.Correlation of mitodhondrial function and age was analyzed with linear regression.Results Activities of complexes Ⅱ (P = 0.001 ),Ⅲ (P = 0.005 )and Ⅳ (P = 0.005 )were reduced in KBD articular chondrocytes compared with cells from normal controls.However,the mitochondrial mass was increased in KBD samples. Cultured KBD chondrocytes had reduced cellular ATP level (P = 0.001 )and mitochondrial membrane potential (P =0.001),but increased citrate synthase activity (P =0.04)and intracellular ROS level (P <0.001).We found no correlation between mitochondrial function and donor age either in normal or in KBD chondrocytes. Conclusion Mitochondrial function is altered in articular chondrocytes of KBD,and no correlation was found between mitochondrial function and donor age.
