Objective To study the effects of PNESF at different voltages on the life spans of ascites tumor bearing mice.Methods Forty ascites tumor bearing mice were divided into 5 groups and exposed to PNESF at 0,10,17,23 and 30 kV,respectively,for 30 minutes daily on 4 successive days.All of the animals then received routine care until death.Their eating habits,body weights and life spans were observed.A straight line fitting method was used for statistical analysis. Results The body weights of the mice exposed to 17 kV and 23 kV PNESF increased quickly during the four days of PNESF exposure.The weight gain in all groups declined after PNESF exposure was stopped.Thereafter the body weights of the mice exposed to the 17 kV PNESF increased more slowly than those in the control group.The mice exposed to the 23 kV PNESF gained weight more quickly than other groups.The mice exposed to the 17 kV PNESF lived the longest,demonstrating a lengthening of life of 25.5%compared with the control group.Conclusion Exposure to a PNESF of appropriate intensity might significantly increase the life span of ascites tumor bearing mice.

To investigate the influence of the extent of attrition of teeth in the elderly and to provide a basis for the treatment, 5 527 teeth of 249 elderly, aged from 60 to 92 years, were examined. The results indicated that the occurrence rate of attrition was 100%, 54.6% of them was slight and 45.4% of them was severe. About 16% of them showed symptoms, and hypersensitivity of teeth was the most common one. The authors tried to individualize the treatment. The teeth with severe attrition were repaired by making plastic-metal plate and occlusive rehabilitation. After treatment all patients′ symptoms were resolved, and masticatory efficiency was improved.

Objective To investigate relationship between different degrees of asymptomatic carotid artery stenosis and cognitive impairment. Methods The cognitive function were evaluated with the montreal cognitive assessment scale (MoCA) in 80 patients with asymptomatic carotid artery stenosis and 56 controls, the total MoCA scores and subprojects scores were compared between the patients with different degrees of ACS and controls. Results The total MoCA score, visual space and executive function, attention and delayed recall had significant difference among the mild, moderate, severe ACS patients and control group (all P < 0.05). There was no statistical significance of the total MoCA score and the scores of all subprojects between the patients of mild ACS patients and the control group (all P > 0.05). The total MoCA score and the scores of visual space and executive function , attention and delayed recall in moderate and severe ACS patients were significantly lower than the control group and mild ACS patients (P < 0.05). Furthermore, the severe ACS patients, compared with the moderate ACS patients , performed worse on the cognitive tasks which involved visual space and executive function, attention and delayed recall (P < 0.05). Conclusions Cognitive function is impaired in the patients with moderate and severe ACS,the neuropsychological characteristics are mainly impaired in visual space and executive function, attention and delayed recall.

Objective To transform knowledge organization systems (KOS) about traditional Chinese medicine (TCM) domain into standardized ontologies, in order to achieve the publication, sharing, and fusion of TCM KOS on the Web, and to further improve the organization and management of TCM knowledge. Methods Simple knowledge organization system (SKOS), a technical specification recommended by World Wide Web Consortium, was used to transform TCM KOS into publishable ontologies on the Web. Results Traditional Chinese medicine language system was transformed into an SKOS ontology, which was stored into a knowledge base that could support SPARQL (standard query language of the Semantic Web) query access, and provide concept, terminology, and knowledge services for Semantic Web applications, such as semantic wiki and semantic search via Web service interfaces. Conclusion This research preliminarily verifies the applicability of SKOS in TCM domain, and exemplifies the process of transforming TCM KOS into SKOS ontologies.

Intravascular ultrasound (IVUS) is a commonly used technology in percutaneous coronary intervention (PCI) procedure. It has higher resolution and repeatability, and more importantly, it can make the vascular structure visiable which shows the plaque morphology and component, compared with traditional coronary angiography. Most researches indicated that IVUS can help doctors find out the optimized stent size, stent malapposition,stent disexpansion,and procedure complication, thus reduce the incidence of restenosis and stent thrombosis. IVUS has been widely applied in research about the predictors of PCI complication, these results benefit us to make better decision on PCI procedure. In this article, we reviewed the studies based on IVUS technology during the last 10 years and summrized according to restenosiss and stent thrombosis with BMS (bare metal stent) and DES (drug eluting stent) .

In the treatment of primary epilepsy, Traditional Chinese Medicine (TCM) compounds and the combination of TCM and Western medicine with acupuncture and moxibustion, massage, acupoint embedding and other therapies are used most. The combined application of different therapies could enhance the curative effect, which could effectively control the frequency of the outbreak of this disease, reduce the adverse reactions of drugs, and further improve the quality of life of patients. In recent years, the number of TCM clinical studies related to this disease has increased, but most of the studies have a small sample size, unclear long-term efficacy, few double-blind trials, and unclear random methods. In addition, the criteria of syndrome classification and curative effect of primary epilepsy need to be unified.

Abstract: Objective　To analyze the genotype of carbapenemase resistance genes and their genetic homology in multidrug-resistant Acinetobacter baumannii, and to provide a theoretical basis for guiding the rational use of antibiotics and controlling the prevalence of nosocomial infections. Methods A total of 83 multidrug-resistant Acinetobacter baumannii isolated from patients in the intensive care unit (ICU) and environmental specimens in the Sixth People's Hospital of Nantong from July 2020 to December 2021 were collected. The bacteria were identified and subjected to drug sensitivity tests using the BioMérieux DL96-Ⅱ automatic bacterial identification susceptibility system. The carbapenemase-related drug resistance gene types were detected using the polymerase chain reaction (PCR) method, and clones were analyzed by pulsed field gel electrophoresis (PFGE). Results The types of 83 ICU Acinetobacter baumannii specimens include sputum (43 strains), broncholavage fluid (20 strains), and surfaces of objects such as ventilators (20 strains). The resistance rates of all strains to imipenem, tetracycline, gentamicin, amikacin and ciprofloxacin were 100%, 32.5%, 38.6%, 41.0% and 77.1% respecitively, while the resistance rates to others such as ticarcillin and clavulanate were greater than 95%. All strains carried were detected to carry OXA-23 and OXA-51 genes, while OXA-24, OXA-58, IMP-1, VIM, IMP-4, SIM and NDM-1 resistance genes were all negative. PFGE homology analysis confirmed that 83 strains of Acinetobacter baumannii, with counts of 12, 18, 12, 13, 10, 6, 7, 5 respectively, mainly A, B, C, D, E clones, the rest were sporadic clones. Conclusions The carbapenem resistant Acinetobacter baumannii isolated from our ICU are widely drug-resistant to commonly used antimicrobial drugs, with B clone strain being the major prevalent strain. Carrying OXA-23 and OXA-51 genes may be an important reason for the resistance of Acinetobacter baumannii to carbapenem antibiotics in our ICU. Rational use of antimicrobial drugs, enhanced monitoring of bacterial resistance, and effective control of the generation and further spread of drug-resistant strains should be emphasized.
