Autophagy is a process for the degradation of long half-life proteins and organelles via the lysosome system. A large body of evidence indicates that the autophagic phenomena exist in the progressive atherosclerotic plaques. Vascular smooth muscle cells, macrophages, and endothelial cells treated with some stimulants that result in atherosclerosis formation in in vitro experiments, these cells show certain autophagic features, such as myelin-like structures, accumulation of ubiquitinated inclusions in the cytoplasm, and extensive vacuolization. However, although the interests in research on autophagy are increasing, the exact role of autophagy in atherosclerosis remains unclear. Therefore, understanding the underlying cellular and molecular mechanisms of autophagy will provide a new idea for studying the mechanisms and treatment of atherosclerotic disease.

Background Based on prior research in the field, a preliminary questionnaire was created to compare the coping strategies of schizophrenic patients to those of non-ill community residents. Results of the comparison were subsequently used to develop a questionnaire suitable for use in schizophrenic patients.Methods Ninety-one of the 92 items in the preliminary questionnaire were identified from previous questionnaires, and one additional item was created based on information provided in individual interviews with schizophrenic patients. This questionnaire was administered to 315 community controls and 208 schizophrenic inpatients. Exploratory Factor Analyses to identify the factor structure of coping strategies were independently conducted for controls and patients. Based on these results, a revised 65-item instrument was developed and administered to a new group of 287 controls and 219 schizophrenic inpatients. Confirmatory Factor Analyses (CFA) using Linear Structural Relations (LISREL) were independently conducted for the two groups to confirm their respective factor structures.Results Six coping categories identified in normal controls were problem solving, avoidance, cognitive adjustment, emotional adjustment, seeking special support, and denial. Among schizophrenic patients, however,coping strategies of "seeking special support" and "denial" were not independent of the other four coping categories. Their items were distributed among the others. Results of CFA confirmed this four-category model of coping strategies for schizophrenic patients.Conclusions Coping categories employed by schizophrenic patients were different from those employed by normal community controls. Schizophrenic patients lacked the necessary flexibility of selecting appropriate coping strategies.

To observe the effects of heterograft of glomus cells of carotid body on hemiparkinsonian rat models, rats with unilateral 6-hydroxydopamine (6-OHDA)-induced lesions of the right dopaminergic neurons of substantia nigra received intrastriatal glomus cells heterograft. Apomorphine-induced rotation was monitored for 30 min at various time points after grafting. The striata were cut and examined for dopamine content by HPLC and for immunohistochemical staining of tyrosine hydroxylase positive neurons (TH+) at the end of the experiments. The results showed that apomorphine-induced rotational behavior was significantly reduced for 12 weeks and the dopamine contents were significantly elevated after grafting (P < 0.01), and TH+ cells survived better. The present study demonstrates that intrastriatal heterograft of glomus cells within carotid body in rats with 6-OHDA-elicited lesions could reduce apomorphine-induced rotational behavior and elevate the dopamine contents and numbers of TH+ cell surviving within striatum, and can serve as a new and effective alternative for Parkinson disease.

OBJECTIVEThe changes of pain threshold and expression of 5-hydroxytryptamine(5-HT) and c-Fos in spinal dorsal horn of rats were observed after targetedly damaged the cerebraspinal fluid-contacting nucleus (CSF-contacting nucleus) to provide experimental evidence for the mechanism of regulating pain CSF-contacting nucleus involved in.

METHODSMale adult SD rats were divided into control, sham, choleratoxin subunit B conjugated with horse-radish peroxidase (CB-HRP)and damage groups randomly. The pain threshold using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were recorded and analyzed. Immunofluorescence method was used to observe the expression of 5-HT and c-Fos in spinal dorsal horn.

RESULTSCompared with the control, sham and CB-HRP groups, the MWT and TWL of the damage group were significantly increased (P < 0.05). The results of immunofluorescence showed that 5-HT was detected in neurons of CSF-contacting nucleus. In the damage group, the number of neurons of CSF-contacting nucleus reduced gradually, and no survived neurons were observed at the 10th day. Meanwhile, both the expression of 5-HT and c-Fos in spinal dorsal horn increased gradually, and negatively correlated with the change of pain threshold.

CONCLUSIONThe method of targeted damaging CSF-contacting nucleus by cholera toxin subnit B conjugated with saporin(CB-SAP) is scientific and reliable, and it results in the changes of pain threshold and expression of 5-HT and c-Fos in spinal dorsal horn of rats. This study suggests that CSF-contacting nucleus participate in the regulation of pain, moreover, 5-HT and c-Fos play important roles in this regulation.

The purpose of this study was to develop a robotic system for image-guided percutaneous interventions using ultrasound (US) or computed tomography (CT) for needle biopsy, ablation, cryotherapy, and other needle procedures. The conventional operation of puncture was analyzed firstly, and a compact robot was then designed for manipulating a needle or other slender surgical instrument in the confined space. Its distinctive characteristic is the decoupled motion capability correlated to the positioning and orientation steps of the percutaneous intervention. This approach allowed each step of the intervention to be performed using a separate mechanism of the robot. One major advantage of this kinematic approach was patient safety.
