ABSTRACT
As a fluorinated hydrocarbon anesthetic, methoxyflurane may cause serious adverse reactions such as renal damage under anesthetic doses, but its analgesic effect at sub-anaesthetic doses is safe, high tolerability, and short-term acute Good choice for analgesia. This article describes the pharmacokinetics, clinical validity, adverse reactions and clinical application of methoxyflurane, and explores the feasibility of methoxyflurane as an analgesic in clinical application. Methoxyflurane is convenient to use as an inhaled analgesic. It can provide patients with emergency analgesia without intravenous administration. It is a good choice for emergency analgesia in pre-hospital and emergency settings.
ABSTRACT
Migraine is a common nervous system disease, which could seriously affect the quality of life. However, the medical treatment of migraine cannot meet the clinical needs at present. With the deepening of research, serotonin 1F receptor agonists and drugs targeting CGRP are more and more developed and marketed. In this paper, the mechanism of action, safety and efficacy, metabolic characteristics of these drugs were systematically evaluated to provide a more scientific basis for clinical prevention and treatment of migraine.
ABSTRACT
Objective To compare classical and molecular typing methods for Streptococcus pneumoniae,in order to provide fasty and accurate method for classification.Methods Selected the 150 strains of Streptococcus pneumoniae which isolated from the First People’s Hospital of Zhaoqing from October 2013 to February 2015 for the research objects,using the classi-cal quellung classification method and molecular typing of multiple PCR method for classification.Compared the result and the rate of the classification,used the non parametric test of two independent samples for statistical analysis several higer rate of serotypes,and calculated the total coincidence rate,sensitivity and specificity.Results The typing rate of Streptococ-cus pneumonia capsular was 53.3%,and the main serum group were 19(32.7%),6(7.3%)and 23(4%)respectively.The serotype of 19F(23.3%),19A(2.7%),6C(2%)and 23F(2.7%)respectively by single factor serum.The typing rate of the multiple PCR method was 76.0%,and the main serum group were 19(41.3%),6(10.7%)and 23(10.7%).The serotype were mainly 19F(32.7%),19A(8.0%),6(10.7%)and 23F(9.3%).Used the 2 Independent Sample Test for statistical a-nalysis,compared with the serotypes 19F,19A and 23F(P>0.05).There was no statistically significant difference in the distribution of the types of the two methods.The total coincidence rate was 74.6%.To verify the classic quellung method by multiple PCR method,sensitivity was 70.2%,and specificity was 100%.That showed the capsular swelling method was less sensitivity than the molecular typing method.Conclusion Compared with the traditional serological typing techniques,mo-lecular typing technique have the advantages of fast,accurate,sensitive and high resolution,and become the classification method which can be rely on.
ABSTRACT
Objective To establish a serological diagnostic method about NSCLC by investigating the expres-sion of 3 tumor markers of the sulfate glycosaminoglyean fragments(SGF), TSGF and CEA in NSCLC patients' serum. Methods To assay the level of SGF,TSGF and CEA in 50 NSCLC patients with latex particleagglutiation test,colori-metry of biochemistry and CLIA, respectively. Compared the clinical value of different examination combination way in NSCLC diagnosis value. Results There was high difference value between the Ⅰ - Ⅱ stage and the Ⅲ time,the Ⅲ time and the Ⅳ time about the level of SGF(P <0.05) in NSCLC patients. The specificity between SGF,TSGF and CEA each single item and the SGF and TSGF combination examination were not significant(P > 0.05). The semitivity between the SGF and TSGF combination and the SGF,TSGF and CEA combination was not significant(P >0.05), its specificity had significant difference(P <0.05). Conclusions There are higher expression about the 3 tumor mark-ers in NSCLC patients' serum. In the different combination examination, SGF and TSGF combined has great clinical value than other combinations to diagnosis NSCLC.
ABSTRACT
Objective To study the influence of infection again to hepatifis B sufferer get disease turn into by human cytomegalovirus(HCMV)afterbirth incubates-activate. Methods The serum levels of HCMV-DNA and HBV-DNA were determined by real-time fluorescent ration PCR, and the HCMV-IgG, IgM level were determined by ELISA in 162 serums from hepatitis patients HBsAg reported the masculine. Results The masculine rate of HCMV-DNA and HCMV-IgM, and the mean vahe of HCMV-DNA ration were much consilient: controls＜hepatitis B sufferer＜hepatocirrhosis＜liver cancer. The masculine rate of HCMV-DNA and HCMV-IgM in hepatitis B HBV-DNA positive patients was higher in hepatitis B HBV-DNA negative patients(P＜0.01). Conclusion Under the multiple infection appearance, it has the certain association with connection which HCMV afterbirth incubates-activate the infection again to hepatitis B get disease turn into.
