RESUMO
Cold atmospheric plasma (CAP), a redox modulation tool, is capable of inhibiting a wide spectrum of cancers and has thus been proposed as an emerging onco-therapy. However, with incremental successes consecutively reported on the anticancer efficacy of CAP, no consensus has been made on the types of tumours sensitive to CAP due to the different intrinsic characteristics of the cells and the heterogeneous design of CAP devices and their parameter configurations. These factors have substantially hindered the clinical use of CAP as an oncotherapy. It is thus imperative to clarify the tumour types responsive to CAP, the experimental models available for CAP-associated investigations, CAP administration strategies and the mechanisms by which CAP exerts its anticancer effects with the aim of identifying important yet less studied areas to accelerate the process of translating CAP into clinical use and fostering the field of plasma oncology.
RESUMO
To systematically collect the relative literatures about'internal heat'caused by taking ginseng, to summarize and analyze the scientific definition of'internal heat'according to Traditional Chinese Medicine (TCM) theory and modern mechanism research. Through literature review, this article also analyzed and discussed the theory of'fire'based on the view of TCM, biochemistry and medicinal chemistry. It has been reported that the excessive and improper use of ginseng might lead'internal heat'. According to TCM theory, excessive nourishment of Qi will lead the generation speed of Qi faster than Blood, which will then cause'fire'. Modern researches indicated that the overdose or improper use of ginseng increased the levels of interleukin, dopamine, adrenal-cortical hormone as well as other biomarkers, which would then cause insomnia, oral ulcer, nose bleeding and other symptoms. Researchers indicated that ginsenoside Ro, ginsenoside Rg1, dencichine as well as panoxadiol, panoxatriol and other secondary ginseng saponin would cause'fire'.However, the conclusion about mechanism study on'fire'was conflicting. The changes on biochemical index caused by the main active components from ginseng are very similar to which caused by'fire'. The chemical substances and their mechanisms on'fire'after the treatment of ginseng still need to be further studied.
RESUMO
Objective To explore the effect of influenza and 23 valent pneumococcal polysaccharide pneumococcal vaccinations on symptom-improvement among elderly with chronic obstructive pulmonary diseases (COPD).Methods Data was gathered from 4 communities in 3 National Demonstration Areas set for comprehensive prevention and control of chronic non-communicable diseases in Chongqing city and Ningbo city respectively,from November 2013 to October 2014.The communities were selected by cluster sampling and divided into 4 groups:(1) injected influenza vaccines;(2) injected with pneumococcal vaccines;(3) received both of the two vaccines;(4) the control group that without any intervention measures.All the subjects aged from 60 to 75 were selected to fill in demographic information questionnaire and receive (COPD assessment test,CAT) scores twice,before intervention and 1 year after the vaccination.SAS 9.4 software was used to analyze the change of symptoms and CAT scores before and after the intervention program and comparing the improvement on symptoms among the elderly people under study.Results A total of 1 244 subjects with nearly same baseline conditions after the propensity score matching,were involved in this study.CAT scores appeared as Median=21 (IQR:17-26) at baseline.The CAT scores appeared as Median=18 (IQR:14-24),decreasing in all the 3 vaccinated groups,one year after the intervention program (influenza vaccines,matching t test,t=-6.531,P=0.403;pneumococcal vaccines,Wilcoxon test,H=-9 623,P＜0.001;combined vaccine vaccines,matching t test,t=-10.803,P＜0.001).However,in the control group,no obvious change was observed (Wilcoxon H=1 167,P=0.403).Proportions of impacts at high or very high levels all decreased in the 3 intervention groups,while little change was observed in the control group.Outcomes from the Factorial analysis suggested that influenza vaccination could improve the general conditions and symptoms including cough,chest tightness,dyspnea,physical activities,and stamina.Pneumococcal vaccination appeared more effective on all of symptoms and indicators.Conclusion Pneumococcal and influenza vaccination seemed helpful for elderly people suffering COPD to improve the general health condition.

RESUMO
Objective To observe the efficacy and safety of remifentanil in patients with mechanical ventilation in Intensive Care Unit (ICU) .Methods Totally 90 cases were enrolled ,patients with mechanical ventilation were randomly divided into two groups (remifentanil vs .fentanyl) ,45 cases in each group .We used facial expression score (FPS) to monitoring pain ,richmond se‐dation agitation score (RASS) was the sedation tool for measuring quality and depth of sedation .Propofol wase used for sedation therapy .We recorded the data including FPS and RASS and vital signs during the treatment .The primary outcome was the time to reach the goal of analgesia sedation ,cases of using propofol and doses of propofol .The secondory outcome was mechanical ventila‐tion time ,ICU length of stay and adverse events .Results Fentanyl and remifentanil all could achieve the desired analgesic effect . Compared with fentanyl group ,FPS scores showed significantly decreased after 5 min application of remifentanil (P0 .05) .The mechanical ventilation time ,ICU length of stay in the patients with remifentanil were significantly shorter(P<0 .05) ,and adverse events occur less(all P<0 .05) .Conclusion Remifentanil analgesia in patients mechanical ventilated patients is fast onset of action ,analgesic effect significantly ,with less sedative drug dosage .It also can shorten mechanical ventila‐tion time ,ICU length of stay and has no obvious side effects .
RESUMO
OBJECTIVE To investigate the bacterial distribution and antibiotic resistance of main pathogens from urinary tract infection (UTI) in our hospital for the guidance of rational use of antibiotics. METHODS The antibiotic resistance of clinical pathogen isolates from urinary tract infection by routine bacterium culture from Jan 2006 to Dec 2007 were studied retrospectively. The extended spectrum ?-lactamases (ESBLs) were detected out to the Gram-negative bacilli. RESULTS There were 722 strains of pathogens in the whole 2773 urinary samples with the isolating rate 26.0%. Most of the Urinary tract infections of patients were caused by Gram-negative bacilli (69.4%),then by Gram-positive cocci (16.3%) and fungi (14.3%). The most common pathogens in urinary tract infection were Escherichia coli (47.9%),Enterococcus faecais (7.9%),E. faecium (4.0%),Proteus mirabilis (3.9%),and Pseudomonas aeruginosa (3.5%). The Gram-negative bacilli were found to be sensitive to imipenem and meropenem,but highly resistant to the most other antibiotics,while P. mirabilis was susceptive to amikacin and cephalosporins. The Gram-positive cocci were more sensitive to nitrofuvantoin and vancomycin,but highly resistant to penicillin,oxacillin and SMT. CONCLUSIONS E. coli is still the primary urinary pathogen among patients,and highly resistant to a lot of antibiotics,We should carry out cultivation,isolation,and antimicrobial susceptibility testing as soon as possible to guide reasonable clinical drug therapy.
