Abstract: Objective To analyze the characteristics of pathogens isolated from patients with lung cancer after surgery, and provide instructions for the prevention and treatment of postoperative infection. Methods A retrospective investigation of the pathogenic microbiology data of 159 patients（142 males and 17 females with average age at 61.8±9.6 years) with lung cancer after surgery in West China Hospital from January 2009 to December 2011 was performed.We got the specimen from the patients by routine methods, identified the pathogens, and conducted drug susceptibility tests in vitro. Results The pathogens were mainly isolated from sputum of the patients （90.6%, 155/171）. Canidia albicans（25.7%, 44/171）, Klebsiella pneumonia（15.2%, 26/171）, Acinetobacter calcoaceticus-A. baumannii（13.4%, 23/171）and Pseudomonas aeruginosa（8.2%, 14/171） were the predominant species. Among A. calcoaceticus-A. baumannii isolates, 39.1%（9/23） of them were multidrug resistant strains. And 23.1%（6/26）of K. pneumonia isolates produced extended spectrum beta-lactamases. P. aeruginosa isolates showed high in vitro susceptibility to the antibacterial agents. Conclusion Pathogens are mainly isolated from sputum of patients after surgery for lung cancer. Canidia albicans and gram-negative bacilli are predominant isolates and should be the major targets for the prevention and treatment of postoperative infection.
Objective To evaluate the effect of music therapy for childbirth. Methods Such databases as The Cochrane Library, PubMed, EMbase, EBSCO host, SpringerLINK Online Journals, CBM and WanFang Data were searched from January of 2000 to December of 2010 to collect randomized controlled trials (RCTs) of music therapy for childbirth. The quality of RCTs was appraised and the data were extracted. Meta-analyses were conducted with RevMan5.02 software for the standarded RCTs. Results A total of nine RCTs were included. Five RCTs indicated the music therapy could alleviate the labor pain; five RCTs indicated the music therapy could reduce the event risk of cesarean section due to the failure of transvaginal trial labor; three RCTs indicated the music therapy could shorten the first stage of labor; two RCTs indicated the music therapy could stabilize the systolic pressure and heart rate when complete cervical dilation was done, and three RCTs indicated the music therapy could relieve anxiety. In addition, music therapy had no influence on neonate Apgar’s score; and the result of meta-analyses on postpartum hemorrhage was not reliable through sensitivity analyses. Conclusion The music therapy applied during childbirth can relieve the labor pain and anxiety, stabilize the heart rate and systolic pressure when complete cervical dilation is done, reduce the event risk of cesarean section due to the failure of transvaginal trial labor, shorten the first stage of labor, and is beneficial to the mind and body of parturient.
Objective To study the special traits of primiparae’s compliance with labor analgesia, so as to offer individualized analgesia solutions during spontaneous labor. Methods The uniparous primiparae with cephalic presentation between gestational weeks 38 and 40 were divided into two groups based on their educational background (college education or above, and high school education or below), each group with 20 cases. The demographical statistics of the two groups including their State-Trait Anxiety Inventory (STAI) grading, PCA results, and delivery situation were recorded and analyzed. Results Differences in age, height, and weight were not statisticallysignificant (Pgt;0.05); differences in T-AI were not statistically significant (Pgt;0.05); differences in S-AI were statistically significant (Plt;0.05); differences in anxiety and numbers of adding anesthetics were not statistically significant (Pgt;0.05); differences in failure to tolerate labor pains and requiring caesarean section were statistically significant (Plt;0.05). Conclusion Primiparae with higher educational degree tend to have higher S-AI grading and perform poorly in compliance with labor analgesia.
Acquired Immunodeficiency Syndrome (AIDS) is a severe infectious disease induced by human immuno deficiency virus (HIV). Laboratory testing plays an important role in the diagnosis of HIV/AIDS. In general, laboratory testing includes detection of virus antibodies and antigens, virus RNA, immune cells (CD4+, CD8+) and anti-HIV drug resistance. During the past twenty years, great progress has been made in laboratory testing. As research on HIV/AIDS has advanced and biotechnology has developed rapidly, different methods of testing have been discovered. In recent years, the application of molecular biotechnology and immunology has led to important advances for epidemiological surveys, clinical diagnosis and treatment of HIV. The existence of a testing method with high sensitivity and specificity is not only helpful for early diagnosis and prediction, monitoring and evaluation of therapeutic efficacy, but can also reduce the risk of false-negative results. HIV laboratory testing is now developing towards a simple, rapid, sensitive, accurate and automatic way of diagnosing this condition.
Objective To assess the effectiveness and safety of local versus systemic application of opioids for labor analgesia. Methods We searched PubMed (1966 to January 2008), EMBASE (1980 to January 2008), The Cochrane Library (Issue 1, 2008), CBM (1978 to January 2008), CNKI (1979 to January 2008) for randomized controlled trials (RCTs) involving local versus systemic application of opioids for labor analgesia. Quality assessment and data extraction were conducted by two reviewers independently. Meta-analyses were conducted with The Cochrane Collaboration’s RevMan 4.2.10 software. Results A total of 12 trials involving 5909 participants met the inclusion criteria. Meta-analyses showed that local application of opioids was superior to systemic application in terms of maternal satisfaction with pain relief during labor (RR 1.63, 95% CI 1.27 to 2.09). No significant difference was found between the two groups in the incidence of low neonatal Apgar score at 5 minutes (RR 0.63, 95% CI 0.40 to 1.01). Conclusion Local application of opioids for labor analgesia appears to be more effective than systematic use in reducing pain during labor. But as for safety concerns, maternal and neonatal adverse effects are observed in both groups. Thus, more high-quality and large-scale RCTs are needed.
