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.

Thyroid cancer is the most common malignant tumor of the human endocrine system. A papillary thyroid microcarci-noma (PTMC) is usually defined as a papillary thyroid tumor that is less than 10 mm in diameter. The incidence of thyroid cancers has obviously increased in recent years. The surgical treatment of PTMC differs in China and overseas. Aside from conventional surgery, novel surgical methods, such as ultrasound-guided percutaneous ablation, have been used for the surgical treatment of PTMC. This arti-cle mainly discusses the research progress in the surgical treatment of PTMC.

Presently,tremendous progress has been achieved in the research of acute pancreatitis (AP),which lead to significant changes in many important aspects of the diagnosis and treatment for AP.In 2014,the Pancreatic Surgery Group of Surgery Branch of Chinese Medical Association revised the Guidelines for the Diagnosis and Treatment of Severe Acute Pancreatitis which was published in 2007.In the revised guidelines,the severity of AP is classified as mild acute pancreatitis (MAP),moderately severe acutepancreatitis (MSAP) and severe acute pancreatitis (SAP).The definition of SAP or MSAP depends on the duration of organ failure,which is persistent (＞48 hours) in SAP but is transient (≤48 hours) in MSAP.Modified CT severity index (MCTSI) is used as the imaging evaluation.Acute peripancreatic fluid collection (APFC),acute necrotic collection (ANC),walled-off necrosis (WON) and pancreatic pseudocyst are the local complications.The disease course is divided into 3 stages,including early stage (acute phase),middle stage (evolution phase) and late stage (infection phase).Infected necrosis is an indication for the surgical treatment,but the surgery should not be performed in sterile necrosis.Meanwhile,surgical treatment should follow the delayed principle.Surgical methods that include percutaneous drainage (PCD),minimally invasive surgery and open surgery could be selected separately orjointly.

The minimally invasive approach is the direction of cardiac surgery.With the development of telemanipulation and computer technology,the minimally robotic surgery has become reality.As the one of the most minimally invasive cardiac surgery,the robotic surgical system provides cardiac surgeons with less invasive manner and dexterity manipulation.Robotic cardiac surgery is an evolutionary process and has resulted in a substantial increased attention to surgeons and patients.This review is to introduce the recent clinical application of robotic technology in cardiac surgery.

Objective To study the level of serum gangliosides ( GM1 and GM3) in patients with gastric cancer and its clinical significance. Methods The ELISA (Enzyme-linked Immunosorbnent Assay, ELISA) method was used to detect GM1 and GM3 content in 40 patients with gastric cancer, and healthy controls. The results were analyzed with statistic software. Results The levels of serum GLS of gastric cancer group were significantly higher than that in healthy group and those in healthy subjects [(815.53±75.56)ng/ml vs (88. 88±32. 73)ng/ml;(765. 92 ±61.09)ng/ml vs (28.03±9.64) ng/ml, P <0.01 ] , patients with gastric cancer after chemotherapy and surgery group, and serum GLS was different between the healthy group and those in healthy subjects, patients with liver cancer after chemotherapy and surgery group. There was positive correlation between GM1 and GM3( r =0. 24, P <0.05).Conclusion Serum GLS of the patients with gastric cancer increased remarkably. Combined detection of serum gangliosides content in gastric cancer will be helpful to diagnosis of gastric cancer,disease progress prediction,and relapse prediction of this disease.

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.
