ABSTRACT
The excellent traditional Chinese time concept embodies and highlights the unique whole universe view of Chinese culture, which is harmonious with all things in heaven and earth, the gradual historical development view, and the life struggle view of calm and steady progress, having important value for the formation and shaping of contemporary medical students’ "three views". To organically integrate Chinese excellent traditional time concept, an important excellent traditional cultural resource, into the ideological and political courses of medical colleges and universities, it is necessary to integrate it with time awareness education of cultivating self-control and self-discipline of medical students, with the historical value education of cultivating self-confidence and self-reliance of medical students, and with the enterprising spirit education to strive for progress in stability under the ideological guidance of the Marxist time concept, the theoretical support of the essential statement on "two combinations" by general secretary Xi Jinping, and the mission guidance of the ideological and political course construction for medical colleges and universities in the new era. Promoting the reform and innovation of ideological and political courses of medical colleges and universities from the perspective of time concept can effectively help medical students in the new era build a systematic time consciousness, form a healthy time concept, and practice a scientific time management method, effectively constructing their humanistic rationality, cultural self-confidence, and historic initiative.
ABSTRACT
BACKGROUND:Surgical treatment is often required for fractures of the cervical vertebrae. Anterior interbody fusion technology is stil the main method for the treatment of cervical degeneration or traumatic instability. Here, the self-made oval al ogeneic bone pad can adapt to different height and width of the intervertebral space, in line with the physiological shape of the intervertebral space. OBJECTIVE:By comparison with autogenous iliac crest bone, to evaluate various types of self-designed al ogeneic bone pads on anterior cervical interbody fusion. METHODS:From January 2009 to December 2013, 58 patients with cervical disc herniation were enrol ed and subjected to cervical discectomy and anterior cervical interbody fusion. According to different bone grafts, these patients were divided into al ogeneic bone pad and autogenous iliac bone groups. The course of disease was 12 to 24 months. The postoperative effect was measured by Japanese Orthopaedic Association (JOA) score, cervical fusion rate, fusion time, operative time, blood loss and rejection rate. RESULTS AND CONCLUSION:At 6 months postoperatively, the JOA score of two groups had no significant difference at 6 months after treatment (P>0.05);the cervical fusion rates were 83.7%and 87.8%, respectively, in the al ogeneic bone pad and autogenous iliac bone groups, with no significant difference (P>0.05). Fusion time was higher in the al ogeneic bone pad than in the autogenous iliac bone group (P<0.05). The internal fixators in the two groups were firmed without loosening, and there was no rejection during the fol ow-up. Compared with the autogenous iliac crest bone, anterior cervical interbody fusion with al ogeneic bone pad can achieve satisfactory effects, which can be better for intervertebral fusion and cannot induce pain due to bone cutting.
ABSTRACT
Objective The individualized treatment of breast cancer have attracted more and more attention .Different mo-lecular subtypes of breast cancer have different kinds of prognosis and therapeutic regimen .Studies have found that miR-342-3p is asso-ciated with breast cancer of hormone receptor and endocrine therapy resistance , as well as tumor cell apoptosis .This study was to fur-ther investigate the expressions of miR-342-3p in different breast cancer molecular subtypes and breast cancer cell lines to reveal the importance of miR-342-3p in individualized treatment of breast cancer . Methods A total of 90 tissue samples from patients with breast cancer surgery were collected .Three types of breast cancer cell line were cultured , including MCF-7, SKBr3 and MDA-MB-231.Real-time fluorescent quantitative PCR was applied to detect the expression of miR-342-3p in breast cancer tissue . Results Expression of the miR-342-3p increased the most in Lumina B type breast cancer tissue (1.594 ±0.465), followed by Lumina A type (1.386 ±0.443), Her-2 high expression type (1.165 ±0.337), and the lowest in the tripe negative breast cancer tissue (0.837 ± 0.351), representing significant difference (P0.05).As to the expression of miR-342-3p in three types of breast cancer cell line , taking SKBr3 as the reference, the relative ratio was 126(118-134) and MDA-MB-231 was 0.017(0.014-0.018). Conclusion The expressions of miR-342-3p are different in different molecular subtypes and cell lines of breast cancer , which are relevant to different molecular subtypes of breast cancer , making it possible reference index for breast cancer typing and relevant to good prognosis .
