Objective To explore relativity between serum cortisol and post-stroke depression in old patients with stroke. Methods Serum cortisols of 41 stroke patients were examined two weeks after stroke, and they were all assessed through Hamilton Depression Scale and then happening rates of post-stroke depression observed in both normal cortisol group and enhanced cortisol group were tested through χ2 test. Meanwhile relativity between serum cortisol level and post-stroke depression were analysised. Results Happening rates of post-stroke depression had an evidently difference between both normal cortisol group and enhanced cortisol group(χ2=4.11;P <0.05). Mark of normal cortisol group was 15.29±7.28, enhanced cortisol group was 25.85±10.81, both groups had an evidently difference( P <0.01). Serum cortisols were not obviously relative to depression degree in normal cortisol group( r =0.295;P =0.194) while they were obviously relative in enhanced cortisol group( r =0.702;P =0.001). Conclusion Enhanced cortisol could forecast higher possibility of depression after the old post-stroke, and detecting cortisol could offer theory foundation for prevention and cure of post-stroke depression.

Objective:To study B cells proliferation and activation induced by tumor derived-autophagosomes ( TDA). Methods:Splenocytes of mice were incubated with 10μg/ml TDAs in vitro ( with the 10μg/ml whole cell lysate as the control).At the 3rd day,the expression of MHCⅠ,Ⅱand co-stimulate molecules including CD86,CD40 were detected by flow cytometry,and B cells proliferation was detected at the 5th day.B cells were selected from spleen of mice using anti-CD43 dynabeads,and incubated with 10μg/ml TDA in vitro ( with the same concentrated whole tumor cell lysate as the control).At the 7th day,IgM in the supernatant were tested by ELISA.Results:When compared with whole cell lysate stimulated B cells,TDA efficently stimulated B cells division in vitro ( TDA group:28.6%, Whole cell lysate group:4.4%) , and significantly up-regulated the expression of MHC class Ⅰ,Ⅱ and co-stimulatory molecules (CD86 and CD40) on B cells,and enhanced the levels of total IgM secretion in vitro.Conclusion:Tumor-derived autophagosomes ( TDA) ,as a vacuole antigen vector, could stimulate B cells proliferation, activation, and increased IgM secretion in vitro.

Voltage-gated sodium channels (VGSCs), which are widely distributed in the excitable cells, are the primary mediators of electrical signal amplification and propagation. They play important roles in the excitative conduction of the neurons and cardiac muscle cells. The abnormalities of the structures and functions of VGSCs can change the excitability of the cells, resulting in a variety of diseases such as neuropathic pain, epilepsy and arrhythmia. At present, some voltage-gated sodium channel blockers are used for treating those diseases. In the recent years, several neurotoxins have been purified from the venom of the animals, which could inhibit the current of the voltage-gated sodium channels. Usually, these neurotoxins are compounds or small peptides that have been further designed and modified for targeted drugs of sodium channelopathies in the clinical treatment. In addition, a novel cysteine-rich secretory protein (CRBGP) has been isolated and purified from the buccal gland of the lampreys (Lampetra japonica), and it could inhibit the Na+ current of the hippocampus and dorsal root neurons for the first time. In the present study, the progress of the sodium channelopathies and the biological functions of voltage-gated sodium channel blockers are analyzed and summarized.

Objective To understand the status quo of knowledge,attitude and practice of clinical nurses’ needlesrick injury (NSI) prevention and its influencing factors.Methods In our cross-sectional study,1020 clinical nurses in different levels of hospitals in Suzhou were recruited to participate the questionnaire survey by stratified cluster sampling.Results The average scores of knowledge,attitude,and practice about NSI prevention were (78.60+15.30),(78.88+8.31) and (70.60+13.86),individually.There was significant correlation among knowledge,attitude and practice.Stepwise regression analysis indicated that knowledge,occupational safety training,section,attitude,rifle,work environment and the level of hospital were the main influencing factors of NSI prevention practice.Condusions NSI prevention knowledge,attitude and practice among clinical nurses are unsatisfactory.Nursing administrators should pay close attention to the nursing staffs’ need of NSI prevention knowledge and provide targeted education to promote the formation of positive attitude,correct bad behaviors and promote healthy behaviors of NSI prevention.

Objective To investigate the level and influencing factors of self-efficacy among nurses with needlestick injuries and explore effective strategies to improve self-efficacy.Methods 713 clinical nurses with needlestick injuries had been enrolled by convenience and stratified sampling method to comphte the investigation using the self-designed demographic questionnaire and General Self-Efficacy Scale.Results The average score of the self-efficacy was (2.70 ±0.52) points.69.1％ of the needlestick injury nurses had the sclf-efficacy score at the middle level; only 19.1％ of them had a higher level score on self-efficacy.Gender,title,section,initiative report,work environment,and occupational safety training were identified as the influencing factors of the self-efficiency.Conclusions Even though more than half of the nurses with needlestick injuries had a middle level self-efficacy,they need further improvement.Other influencing factors should be explored in future in order to develop the corresponding management intervention which can strengthen the self-efficacy of nurses with needlestick injuries.

Objective To assess the absorbance rate of the fat after the operation of breast augmentation of the repeated injection of low volume, using ultrasonic imaging method. Methods Thirty three patients were injected with low volume of autologous fat (50-60 ml per time) to bilateral breasts for 1-5 times and breast sonographic examination was performed to evaluate the grafted fat tissues. The thickness of the retromammary fat layer before and after each injection was measured to calculate the absorbance index. Results The 264 points of breast were measured in this study. The fat was distributed in the retro-mammary fat layers at 224 points of the breast and in the pectoralis major muscle layer at 32 points of the breast, and the others distributed in the mammary gland layer.The average thickness of the retromammary fat layer increased gradually from 0.2 cm before the first operation to 1. 0 cm after the fifth operation. The average absorbance index one month after each operation was 34 %-66 %. Conclusion The present study demonstrates that breast augmentation by repeated autologous fat graft with low volume injection at each time is applicable and satisfactory and that breast ultrasound is an accurate and simple method to e-valuate the absorbance index.

Objective:To investigate the presence of SENV infection among patients in China,and analyze partial nucleotide sequence of SENV isolated from a patient with non A-G hepatitis.Methods:A nested polymerase chain reaction (PCR) assay with primers from ORF1 of SENV genome was established to detect SENV DNA.The PCR product was cloned and sequenced.Results:SENV DNA was positive in 2 of 7 patients with non A-G hepatitis and TTV negative.Partial gene of a SENV isolate was compared with the corresponding region of SENV isolate(AX025730)from Italy and was found that the nucleotide homology was 90%.Conclusions:The results of this study confirmed the presence of SENV infection in China.The development of a PCR assay for SENV DNA detection and the cloning,sequencing of the SENV isolate have important implication for the diagnosis and epidemiological investigation on SENV infection.
