摘要： Vestibular signals used for balance controlmust be integrated with other sensorimotor cues to allowtransformation of descending signals according to an internal representation of body configuration. We explored two alternative models of sensorimotor integration that propose (1) a single internal representation of head-on-feet orientation is responsible for perceived postural orientation and standing balance or (2) conscious perception and balance control are driven by separate internal representations. During three experiments, participants stood quietly while passively or actively maintaining a prolonged head-turned posture (> 10 min). Throughout the trials, participants intermittently reported their perceived head angular position, and subsequently electrical vestibular stimuli were delivered to elicit whole-body balance responses. Visual recalibration of head-on-feet posture was used to determine whether static visual cues are used to update the internal representation of body configuration for perceived orientation and standing balance. All three experiments involved situations in which the vestibular-evoked balance response was not orthogonal to perceived head-on-feet orientation, regardless of the visual information provided. For prolonged head-turned postures, balance responses consistent with actual head-on-feet posture occurred only during the active condition. Our results indicate that conscious perception of head-on-feet posture and vestibular control of balance do not rely on the same internal representation, but instead treat sensorimotor cues in parallel and may arrive at different conclusions regarding head-on-feet posture. The balance system appears to bypass static visual cues of postural orientation and mainly use other sensorimotor signals of head-on-feet position to transform vestibular signals of head motion, a mechanism appropriate for most daily activities.

关键词： Dexmedetomidine   inguinal hernia repair   conscious sedation   recovery  

摘要： Objective The ideal agents for conscious sedation during ambulatory inguinal hernia repair are still unclear. We aimed to compare the analgesic, sedative, haemodynamic, and side effects of dexmedetomidine with those of propofol in combination with fentanyl for conscious sedation in patients undergoing inguinal hernia repair. Methods Eighty patients undergoing unilateral inguinal hernia repair were prospectively randomized to receive either dexmedetomidine (n=40) or propofol (n=40). Dexmedetomidine and propofol dosages were adjusted to maintain the targeted level of sedation. Results After administration of sedative drugs, patients who received dexmedetomidine had a significantly lower heart rate. The intraoperative requirement of fentanyl was significantly lower in patients who received dexmedetomidine compared with patients who received propofol. Administration of dexmedetomidine was associated with a reduced postoperative pain score, longer time for onset of sedation, and a slightly longer recovery time. No serious adverse events occurred in either group. The patients' overall satisfaction score was comparable between the two groups. Conclusion Dexmedetomidine is an effective adjuvant when co-administered with fentanyl for conscious sedation in patients who undergo inguinal hernia repair. Administration of dexmedetomidine decreases the requirement of fentanyl and the pain score, but slightly prolongs the time to sedation and recovery.

摘要： Conjugation of Doxorubicin (DOX) to N-(2-hydroxypropyl) methylacrylamide copolymer (HPMA) has significantly reduced the DOX-associated cardiotoxicity. However, the reports on the impact of HPMA-DOX conjugates on the cardiovascular system such as blood pressure (BP) and heart rate (HR) were in restrained animals using tail cuff and/or other methods that lacked the resolution and sensitivity. Herein, we employed radiotelemetric-spectral-echocardiography approach to further understand the in vivo cardiovascular hemodynamics and variability post administration of free DOX and HPMA-DOX. Rats implanted with radio-telemetry device were administered intravenously with DOX (5mg/kg), HPMA-DOX (5mg DOX equivalent/kg) and HPMA copolymer and subjected to continuous cardiovascular monitoring and echocardiography for 140 days. We found that DOX-treated rats had ruffled fur, reduced body weight (BW) and a low survival rate. Although BP and HR were normal, spectral analysis indicated that their BP and HR variabilities were reduced. All rats exhibited typical signs of cardiotoxicity at histopathology. In contrast, HPMA-DOX rats gained weight over time and survived. Although BP, HR and related variabilities were unaffected, the left ventricular end diastolic volume (EDV) of these rats, as well as of the HPMA copolymer-treated rats, was found increased at the end of observation period. Additionally, HPMA copolymer caused microscopic injury of the heart tissue. All of these suggest the necessity of caution when employing HPMA as carrier for prolonged drug delivery. The current study also indicates the potential of radiotelemetric-spectral-echocardiography approach for improved preclinical cardiovascular risk assessment of polymer-drug conjugate and other nano-sized-drug constructs.

关键词： 自我意识情绪   心理控制源   青少年  

摘要： 青少年时期是自我意识发展最迅速的时期,作为一种由"自我"参与的高级情绪,自我意识情绪对激发和调节青少年的思想、情感和行为有着重要作用。心理控制源属于认知系统这个重要的青春期发展任务,对青少年而言,其内控性能显著正向预测良好社会适应行为,外控性则显著的正向预测不良社会适应行为。自我意识情绪在自我归因和自我评价的基础上产生,归因理论是心理控制源的理论基础,同时有研究证明心理控制源也是核心自我评价的特质之一。为了进一步研究自我意识情绪和心理控制源之间的相互作用,本研究通过对519名青少年施测自我意识情绪问卷—青少年版(TOSCA-A)和儿童控制知觉多维度测查表(MMCPC),来研究自我意识情绪和心理控制源的关系。研究结果显示:(1)自我意识情绪问卷—青少年版(TOSCA-A)具有良好的信效度,可做进一步研究。(2)羞愧与心理控制源存在显著正相关。(3)内疚与有势力的他人呈负相关,与内部控制呈正相关。(4)α自豪和β自豪与内部控制呈正相关,α自豪与有势力的他人也呈正相关。(5)外化和疏离均与未知方控制、有势力的他人控制正相关显著。因此得出以下结论:(1)自我意识情绪问卷—青少年版(TOSCA-A)信效度良好,可以有效评鉴青少年的自我意识情绪。(2)自我意识情绪和心理控制源之间存在相关。
