AIM:To investigate whether percutaneous endoscopic gastrostomy (PEG) tube placement is safe in patients with ventriculoperitoneal (VP) ***: This was a retrospective study of all patients undergoing PEG insertion at our institution between June 1999 and June 2006. Post-PEG complications were compared between two groups according to the presence or absence of VP shunts. VP shunt infection rates, the interval between PEG placement and VP shunt catheter insertion, and long-term follow-up were also ***: Fifty-five patients qualified for the study. Seven patients (12.7%) had pre-existing VP shunts. All patients received prophylactic antibiotics. The complication rate did not differ between VP shunt patients undergoing PEG (PEG/VP group) and non-VP shunt patients undergoing PEG (control group) [1 (14.3%) vs 6 (12.5%), P=1.000]. All patients in the PEG/VP group had undergone VP shunt insertion prior to PEG placement. The mean interval between VP shunt insertion and PEG placement was 308.7 d (range, 65-831 d). The mean follow-up duration in the PEG/VP group was 6.4 mo (range, 1-15 mo). There were no VP shunt infections, although one patient in the PEG/VP group developed a minor peristomal infection during ***: Complications following PEG placement in patients with VP shunts were infrequent in this study.

随着人口老龄化现象以惊人的速度席卷全球,各国都在积极推动健康老龄化和积极老龄化,身体活动不足和久坐行为已严重影响到人们的健康,甚至与全因死亡率和跌倒风险有关。年龄歧视和老龄化焦虑是实现健康老龄化的主要阻碍因素之一,老年人的身心健康问题直接影响到整个社会的健康,是我们面临的重大课题。研究目的:调查中老年群体的BMI、久坐行为、身体活动水平,年龄歧视和老龄化焦虑的现状及其相互间的关联性,为即将步入老年阶段的中老年群体提高晚年幸福感,构建积极健康的老年生活提供基础资料。研究方法:采取随机抽样的方法于2023年在中国S地区选取264名中老年人(男性87名,女性177名)为调查对象。根据性别、BMI(kg/m2)、婚姻状况、吸烟状况、受教育程度、主观健康状况等因素分层对中老年群体的身体活动水平、年龄歧视和老龄化焦虑程度进行问卷测量。身体活动水平分为高强度(VPA)、中强度(MPA)、低强度(LP A),每次至少持续10分钟才记录为有效。数据分析使用SPSS 22.0和AMOS 25.0统计软件进行因子分析、t检验、Pearson's r、方差分析(ANOVA)和路径分析。研究结果:结果表明,61.8%的中老年群体的BMI值高于正常数值范围;中老年群体的久坐行为、身体活动水平的调查结果显示,男性的久坐行为、VPA、MPA均高于女性的水平;中老年群体的BMI与VPA呈负相关关系(r=-.148, p=.016),BMI与MPA呈负相关关系(r=-.164, p=.008),久坐行为与LPA成负相关关系(r=-.135, p=.028);中老年群体的年龄歧视与老龄化焦虑呈正相关关系(r=.539,p=.000)。结论:VPA和MPA不同程度会影响中老年群体的BMI指数,适当增加身体活动量,减少久坐行为,能有效降低老年人的BMI指数。为改善老龄化社会结构中的老龄化焦虑,实现健康老龄化,不仅需要社会结构层面的努力,还需要减少社会群体中的年龄歧视,提高个体对健康老龄化的再认识,促使中老年人为今后步入健康老年生活做好充分准备。

Daily meat consumption produces a lot of bone waste, and dumped bone waste without treatment would result in environmental hazards. Conventional treatment methods of waste bones have some disadvantages. Herein, an investigation of bone waste treated using thermal plasma technology is presented. A high-temperature plasma torch operated at 25.2 kW was used to treat bone waste for seven minutes. The bone waste was finally changed into vitric matter and lost 2/3 of its weight after the treatment. The process was highly efficient, economical, convenient, and fuel-free. This method could be used as an alternative for disposal of bone waste, small infectious animals, hazardous hospital waste, etc.

Repetitive transcranial magnetic stimulation （rTMS） has been utilized as a therapeutic tool for neurodegenerative disorders including Alzheimer＇s disease. However, the precise mechanisms of its clinical effects remain unknown. β-amyloid （Aβ） exhibits direct neurotoxic effects and is closely related to neuronal degeneration in Alzheimer＇s disease. Therefore, it has been hypothesized that the neuroprotective effects of rTMS are related to the mechanisms of protection against Aβ neurotoxicity. Organotypic hippocampal slices were prepared from 8-day old, Sprague Dawley rats. The tissue slices were exposed to 100 μmol/L Al3142 since day 12 in vitro with and without high-frequency （20 Hz） magnetic stimulation. Magnetic stimulation efficacy was evaluated by measuring neuronal nuclei （NeuN） protein expression and by observing cultures following propidium iodide fluorescence staining and bromodeoxyuridine （BrdU） immunohistochemistry. Lactate dehydrogenase activity was detected in the culture media to evaluate hippocampal neuronal damage. Our results demonstrated that high-frequency magnetic stimulation significantly reversed the reduction of NeuN protein expression because of Aβ1-42 exposure （P 〈 0.05） and significantly reduced the number of damaged cells in the hippocampal slices （P 〈 0.05）. However, lactate dehydrogenase levels and anti-BrdU staining results did not reveal any statistical differences These findings indicate that high-frequency magnetic stimulation might have protective effect on hippocampal neurons from Aβ1-42 neurotoxicity.

AIM: To compare the hemostatic efficacy and safety of two mechanical endoscopic methods: endoscopic band ligation (EBL) and endoscopic hemoclip placement (EHP) in patients with actively bleeding Mallory-Weiss syndrome (MWS). METHODS: A prospective randomized study to compare the efficacy and safety of EHP with EBL was performed from January 2002 to August 2005. Forty-one patients with active bleeding from MWS were treated with EHP (n = 21) or EBL (n = 20). RESULTS: There were no significant differences between groups with respect to clinical and endoscopic characteristics. The mean number of hemoclips applied was 3.2 ± 1.5 and the mean number of bands applied was 1.2 ± 0.4. Primary hemostasis was achieved in all patients. Recurrent bleeding was observed in one patient from the EHP group and two from the EBL group. Patients with recurrent bleeding were treated by the same modality as at randomization and secondary hemostasis was achieved in all. There were no significant differences between the two groups in total transfusion amount or duration of hospital stay. No complications or bleeding-related death resulted. CONCLUSION: EHP and EBL are equally effective and safe for the management of active bleeding in patients with Mallory-Weiss syndrome, even in those with shock or comorbid diseases.

Background： The chicken gastrointestinal tract contains a diverse microbiota whose composition and structure play important roles in gut functionality. In this study, microbial shifts resulting from feed supplementation with Bacillus subtilis CSL2 were evaluated in broilers challenged and unchallenged with Salmonella Gallinarum. To analyse bacterial community composition and functionality, 454 GS-FLX pyrosequencing of 16 S r RNA gene amplicons was ***： The Quantitative Insights into Microbial Ecology（QIIME） pipeline was used to analyse changes in the faecal microbiota over a 24-h period. A total of 718,204 sequences from broiler chickens were recorded and analysed. At the phylum level, Firmicutes, Bacteroidetes, and Proteobacteria were the predominant bacterial taxa. In Salmonellainfected chickens（SC）, Bacteroidetes were more highly abundant compared to control（NC） and Bacillus-treated（BT）chickens. At the genus level, in the NC and BT groups, Lactobacil us was present at high abundance, and the abundance of Turicibacter, unclassified Enterobacteriaceae, and Bacteroides increased in SC broilers. Furthermore, taxon-independent analysis showed that the SC and BT groups were compositional y distinct at the end of the 24-h period. Further analysis of functional properties showed that B. subtilis CSL2 administration increased gut-associated energy supply mechanisms（i.e. carbohydrate transport and metabolism） to maintain a stable microbiota and protect gut ***： This study demonstrated that S. Gallinarum infection and B. subtilis CSL2 supplementation in the diet of broiler chickens influenced the diversity, composition, and functional diversity of the faecal microbiota. Moreover, the findings offer significant insights to understand potential mechanisms of Salmonel a infection and the mode of action of probiotics in broiler chickens.

The application-specific multiprocessor system-on-chip(MPSoC) architecture is becoming an attractive solution to deal with increasingly complex embedded applications,which require both high performance and flexible programmability. As an effective method for MPSoC development,we present a gradual refinement flow starting from a high-level Simulink model to a synthesizable and executable hardware and software specification. The proposed methodology consists of five different abstract levels:Simulink combined algorithm and architecture model(CAAM),virtual architecture(VA),transactional accurate architecture(TA),virtual prototype(VP) and field-programmable gate array(FPGA) emulation. Experimental results of Motion-JPEG and H.264 show that the proposed gradual refinement flow can generate various MPSoC architectures from an original Simulink model,allowing processor,communication and tasks design space exploration.
