随着“以学生为中心”教育理念不断深入人心,高校转专业政策条件逐渐放宽,为更多大学生提供了二次选择专业的机会。通过对河南中医药大学康复治疗专业大一年级全体学生以及大二至大五年级成功转出或转入该专业的学生进行问卷调研、访谈交流等发现,大部分本科生转专业的动机是就业前景,转专业后学生的人际交往、课业成绩、参与课外活动的时间等变化都影响着学生的适应性。为使转专业学生能更好地适应新环境,高校应在大一阶段就开设职业规划课程,引导学生合理进行职业规划,及时为转专业学生提供帮助,全方位提升其适应能力。学生也应结合自身选择更适合自己的专业,并能主动学习新专业的知识,确保成绩稳定。

目的:观察针刺对自发性高血压大鼠(SHR)血压、粪便短链脂肪酸(SCFAs)及toll样受体4(TLR4)/髓样分化因子88(My D88)/核因子κB(NF-κB)信号通路的影响,探讨针刺降压的作用机制。方法:将24只SPF级雄性SHR随机分为模型组、西药组、针刺组和假针组,每组6只;另设6只Wistar-Kyoto(WKY)大鼠为空白组。西药组予氢氯噻嗪溶液灌胃;针刺组针刺双侧“人迎”“足三里”,每次20 min;假针组针刺双侧“人迎”“足三里”附近的非经非穴点,每次20 min。均每日1次,持续4周。干预前及干预第1、2、3、4周后测量各组大鼠尾动脉收缩压(SBP);HE染色观察大鼠结肠组织形态;气相色谱-质谱联用仪检测大鼠粪便SCFAs含量;ELISA法检测大鼠血清白细胞介素(IL)-6、IL-1β和肿瘤坏死因子-α(TNF-α)含量;Western Blot法检测大鼠肠系膜动脉中TLR4、My D88和NF-κB p65蛋白表达。结果:与空白组比较,模型组大鼠SBP升高(P<0.05),结肠组织有明显病理变化,粪便SCFAs含量降低(P<0.05),血清IL-1β、IL-6和TNF-α含量升高(P<0.05),肠系膜动脉中TLR4、My D88、NF-κB p65蛋白表达升高(P<0.05)。与模型组比较,针刺组和西药组大鼠干预2、3、4周后SBP降低(P<0.05),血清IL-1β、IL-6和TNF-α含量降低(P<0.05);针刺组大鼠结肠组织黏膜上皮完整,肠腺数量丰富,粪便SCFAs含量升高(P<0.05),肠系膜动脉中TLR4、My D88、NF-κBp65蛋白表达降低(P<0.05)。与假针组比较,针刺组干预2、3、4周后SBP降低(P<0.05),粪便SCFAs含量升高(P<0.05),血清IL-1β、IL-6和TNF-α含量降低(P<0.05),肠系膜动脉中TLR4、My D88、NF-κB p65蛋白表达降低(P<0.05)。结论:针刺双侧“人迎”“足三里”可有效降低SHR血压,其机制可能与调节粪便SCFAs含量、抑制TLR4/My D88/NF-κB信号通路有关。

Satellite integrity monitoring is vital to satellite-based augmentation systems,and can provide the confdence of the diferential corrections for each monitored satellite satisfying the stringent safety-of-life requirements.Satellite integrity information includes the user diferential range error and the clock-ephemeris covariance which are used to deduce integrity probability.However,the existing direct statistic methods sufer from a low integrity bounding percentage.To address this problem,we develop an improved covariance-based method to determine satellite integrity information and evaluate its performance in the range domain and position domain.Compared with the direct statistic method,the integrity bounding percentage is improved by 24.91%and the availability by 5.63%.Compared with the covariance-based method,the convergence rate for the user diferential range error is improved by 8.04%.The proposed method is useful for the satellite integrity monitoring of a satellite-based augmentation system.

Mg-Y cast alloy shows excellent ductility(elongation to failure>15%)compared with pure Mg and commercial Mg cast alloys.By monitoring the microstructure evolution during an in situ tensile test of a Mg-2.5 wt%Y alloy,we identify the activation of prismaticslip,which is rare in Mg.Synchrotron X-ray micro-beam Laue diffraction(μ-Laue)and transmission electron microscopy revealed the morphology of prismaticslip bands and individualdislocations.Density functional theory and molecular dynamics calculations indicate that solute Y can significantly reduce the stacking fault energy(SFE)alongdirection on prismatic plane in Mg lattice and thus facilitate the nucleation ofdislocations during deformation.The presence of freedislocations in the Mg lattice can also lead to nucleation of{10–12}twins even under unfavorable geometric conditions.

OBJECTIVE: To analyze the serum metabolic targets of the "Zhibian(BL54) through Shuidao(ST28)" acupuncture technique in cyclophosphamide(CTX)-induced premature ovarian insufficiency(POI) model rats and to elucidate the potential molecular mechanism of acupuncture in improving POI. METHODS: We used an intraperitoneal injection of CTX to establish the POI rat model(POI group) and compared serum hormone levels and ovarian histopathological changes to evaluate the effect of the Zhibian(BL54) through Shuidao(ST28) technique(ZS + POI group) on ovarian function. Then, nontargeted metabolomics was performed using rat serum by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS). RESULTS: After acupuncture intervention, the serum hormone levels and ovarian pathological morphology of POI rats were effectively improved. Moreover, UPLC-Q-TOF/MS results showed that the ZS+POI group showed a significant reversal of the levels of 6 differential metabolites. Among them, the levels of four serum metabolic markers, divanillyltetrahydrofuran ferulate, trans-ferulic acid, tryptamine, and neuraminic acid, increased significantly. Further analysis of biological effects showed that all metabolites were involved in the regulation of reproductive hormone levels and antioxidant and antiapoptotic effects. CONCLUSIONS: The "Zhibian(BL54) through Shuidao(ST28)" acupuncture method may improve the ovarian function of POI rats by regulating serum metabolite markers to exert antioxidant and antiapoptotic effects, which provides a theoretical basis for the clinical application of acupuncture in the treatment of POI.
