ObjectiveTo analyze the relationship among depression and anxiety and other possible factors in post-stroke patients.Methods510 hospitalized stroke patients from 1997 to 2004 were evaluated with the Scale of Elderly Cognitive Function (SECF), Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), and Activities of Daily Living (ADL) in 7 days after admission and re-examined after two months.ResultsThe depression group exhibited the longer course of disease, a high ratio of hemiplegia in left side, lower ADL scores and higher SAS scores at time of admission. There were significant differences between depression and non-depression group. However, there was no significant difference between the depression and cognitive function. There were also significant differences between anxiety group and non-anxiety group. Patients with anxiety displayed symptoms of low ADL scores and higher SDS scores at time of admission, and ADL scores increased after treatment. Additionally, the course of disease was longer and reduction of anxiety level was lower. The levels of depression and anxiety significantly reduced in depression group and anxiety group when compared to the control group.ConclusionEarly rehabilitation can help to reduce depression level. Modest anxiety may help stroke patients to improve their ADL. There is close relationship between depression and anxiety.

ObjectiveTo compare the effect of psychological treatment only and psychological combined with fluoxetine treatment in reducing symptom of depression, anxiety and in improving of cognitive and daily living abilities for post-stroke depression patients.MethodsAll patients with post-stroke enrolled in hospital between 1996 and 2001 and were evaluated by using of the Self-rating Depression Scale (SDS), the Self-rating Anxiety Scale (SAS), Scale of Elderly Cognitive Function (SECF), and Ability of Daily Living (ADL). SDS score was equal or greater than 50 points (SDS≥50) selected as subjects for this study. A total of 115 patients were randomized divided into psychological with fluoxetine treatment group (Group A,54 patients) and psychological treatment group (Group B,61 patients). There is no significant difference between two groups in age, education, and left or right side of hemiplegics. Statistical analysis was performed by using Chi test and t test to compare the 2 groups at day 0 (baseline) and after 2 months.ResultsThe level of depression and anxiety reduced significantly in both Group A and Group B from baseline to end of treatment (P<0.001). Both groups had significant improvement in daily living ability (P<0.001).There was no significant improvement in cognitive ability (P>0.5). There was no significant differences on SDS, SAS, SECF, and ADL scores from baseline to end of treatment (P>0.5).Conclusions There were similar effect of psychological with fluoxetine treatment and of psychological treatment only on post-stroke depression.

As an evolutionary process, the robotic technology has been recently applied in the minimally invasive surgery. The robotic surgical system can provide cardiac surgeons with less invasive manner and dexterity manipulation in coronary artery bypass graft. The robotic minimally invasive coronary artery bypass graft usually includes robotic internal thoracic artery harvesting, robotic assistant coronary artery bypass graft and totally robotic coronary artery bypass graft.

Objective To establish and assess a model of abdominal postoperative fatigue syndrome (POFS) in rats. Methods After 70% hepatectomy was performed, the following observations of the animals were made:general condition, rat tail suspension test,weight carrying swim fatigue test,serum levels of albumin,ferrition,and iron,pathologic assessment of injury of small intestinal mucosa and hepatic albumin gene expression .Results After 70% hepatectomy of the rats,their general candition was poor,the level of physical tolerance decreased,they showed a certain amount of depression,and marked changes were found in nutritional index,stress injury of small intestinal mucosa and hepatic albumin gene expression.Conclusions A 70% hepatectomy rat model has the basic characteristics of clinical abdominal POFS, and can be used as an experimental animal model for the study of abdominal POFS.

OBJECTIVE:To clarify the current situation of technologies for preparation of nanomedicine.DATA SOURCES: A search of Elsevier database was performed using the key terms "nanomedicine, preparation,nanoparticle, ultrafine powder, microsphere, drug, controlled release" from January 2000 to September 2006. Meanwhile,we also searched the China Journal Full-text Database for the related articles published between January 2000 to September 2006 with the key words "nanomedicine, preparation, powder, microsphere, controlled release" in Chinese.STUDY SELECTION: Articles were selected primarily after their abstracts being read, and related articles accorded with the criteria were collected and read entirely.DATA EXTRACTION: Totally 268 articles about nanomedcine were collected. Those repetitive or similar researches were excluded, and 38 articles met the research criteria.DATA SYNTHESIS: Nanomedicine consists of macromolecular conjugates and particulate drug carriers. The materials are stable but also degradable and biocompatible. At present, many technologies have been used for preparing nanomedicine, such as, emulsion, microemulsion, ultrasonic solvent-nonsolvent, spay drying and high-pressure homogenization, and so on.CONCLUSION: The application of nanomedicine carrier and nanotechnology not only sheds a new light on the traditional drugs whose applications are strongly restricted by their poor solubility, high toxicity and poor stability, but also enhances their therapeutic efficiency with lower dosage through targeting effect.

According to the national residency training regulations in the teaching of clinical and scientific research, the department of thoracic surgery of First Affiliated Hospital of Chongqing Medical University has used seminar teaching , and has collected random sampling survey questionnaire of 110 students participating in seminar from September 2014 to March 2016. The investigation shows that through seminar teaching training, doctors will cultivate their clinical and research ability, and enhance their self-confidence. Therefore, the application of seminar teaching in department of thoracic surgery is helpful to improving the quality of clinical teaching and is worthy of further improvement and promotion.
