Objective To explore the role of p170, MRP, bcl-2 in clinical drug- resistance and their correlation. Methods There are 44 acute leukemia(AL) patients, among them ANLL is 29, ALL is 15.The expression of p170, MRP, bcl-2 were detected. At last, the patients were divided into two groups: CR and NR according to efficacy after two periods standard chemotherapy. Results Overexpression of p170, MRP,bcl-2 were found in AL (P ＜0.05). The expression of p170 and MRP were lower in CR group than that in NR groups in AML and ALL; there were 22 of 24 patients expressed one or two proteins in NR groups and the expression of p170 in patients was concordant with that of MRP to certain extent (P ＜0.01). The overexpression of bcl-2 was related with the worse prognosis. The expression of bcl-2 was lower significantly in CR group than in CR and NR (P＜0.05). Conclusion p170, bcl-2, MRP are all associated with clinical MDR. High expression of these proteins is an unfavorable factor to prognosis. The expression of MRP and p170 showed coincidence, but showed no significance with expression of bcl-2 in untreated patients, it indicated that the drug-resistance mediated by p170 was different from bcl-2.

0.05). Conclusions The gap junction formed by CX43 should be an important role in switching and developing the epilepsy. The synthetic polypeptide corresponding to amino acid sequence of CX43 would be a kind of new type antiepileptic drug, which might have less side effects and more potent pertinency.

Objective To explore the predicting value of quantitative CT features of peritumoral nodules for the risk of thymic epi-thelial tumors(TETs).Methods A total of 108 patients with TETs confirmed by pathology were analyzed retrospectively.Accord-ing to the WHO classification of thymic tumors,the patients were divided into high-risk group and low-risk group.The quantitative CT features included the long diameter,volume,mass,and distance between peritumoral nodules and main tumor.The values of these features were assessed using the Mann-Whitney U test,and the thresholds were determined using the receiver operating characteristic(ROC)curve.Results Among 108 TETs patients,there were 45 patients with peritumoral nodules on chest CT,including 30 high-risk group and 15 low-risk group,respectively.Interobserver consistencies were well with intraclass correlation coefficient(ICC)between 0.886 and 0.907.The long diameter,volume,and mass of peritumoral nodules were greater in the high-risk group than in the low-risk group(P＜0.05),and there was no significant difference in the distance to the main tumor(P＞0.05).The mass of peritumoral nodules had the best diagnostic performance in predicting TETs risk,and the thresholds was 27.84 mg with the area under the curve(AUC)of 0.889,sensitivity of 83.3％,specificity of 87.5％,and accuracy of 85.3％,respectively.Conclusion The quantitative CT features of peritumoral nodules especially mass can be useful in predicting the risk of TETs.

Objective:To explore the effectiveness of limb motor rehabilitation program based on patient health engagement (PHE) model in patients with hemorrhagic stroke, and to provide reference for the limb motor rehabilitation management of hemorrhagic stroke patients.Methods:Through literature review and Delphi expert correspondence, a limb motor rehabilitation program for hemorrhagic stroke patients based on the PHE model was constructed. A non-contemporaneous controlled study was conducted, 45 hemorrhagic stroke patients hospitalized in the Department of Neurosurgery of Shanxi Bethune Hospital from March to August 2022 were selected by convenience sampling method as the control group, and routine exercise rehabilitation measure was given, 45 hemorrhagic stroke patients from September 2022 to February 2023 were selected as the intervention group, a limb motor rehabilitation program based on PHE model was implemented on the basis of control group. The functional exercise compliance, limb motor function, daily activity ability, emotional and social dysfunction of patients in the two groups were observed before intervention, 1 and 3 months after intervention respectively.Results:A total of 85 patients with hemorrhagic stroke were included. There were 42 patients in the intervention group, 25 males and 17 females, aged (52.07 ± 9.91) years old, and 43 patients in the control group, 21 males and 22 females, aged (53.93 ± 10.52) years old. There were no significant differences in the functional exercise compliance, limb motor function, daily activity ability, emotional and social dysfunction of patients before intervention between the two groups. At 3 months after intervention, the functional exercise compliance score in the intervention group was (40.83 ± 7.92) points, higher than that in the control group (37.14 ± 6.44) points, and the difference was statistically significant ( t = 2.36, P<0.05). At 1 and 3 months after intervention, the scores of limb motor function and daily activity ability in the intervention group were (27.12 ± 6.74), (33.67 ± 6.54) points and (61.31 ± 6.72), (74.40 ± 8.71) points, which were higher than (24.91 ± 6.03), (27.02 ± 6.59) points and (52.33 ± 9.78), (60.12 ± 10.03) points of the control group, the differences were statistically significant ( t values were 2.06-7.01, all P<0.05), the scores of emotional and social dysfunction were (75.52 ± 22.09) and (58.33 ± 18.88) points, which were lower than (86.02 ± 23.04), (78.51 ± 21.67) points of the control group, and the differences were statistically significant ( t = - 2.14, - 4.57, both P<0.05). Conclusions:The limb motor rehabilitation program based on the PHE model could improve the exercise compliance of patients with hemorrhagic stroke, improve the limb motor function and daily activity ability of patients, alleviate negative emotions, and reduce the level of social dysfunction.
