Objective To explore the significance of sample cultivation and drug resistance of the patients in PICU with severe lower respiratory tract specimens.Methods 1 107 pathogenic bacteria of lower respiratory tract samples collected were analyzed and the drug resistance was kept watch on.Results A total of 1107 samples were cultured into 948 strains of pathogens,with the positive rate of 85.64%,and 616 strains of Gram negative bacteria accounting for 64.98%,of which 145 strains of Pseudomonas aeruginosa(15.30%),Klebsiella pneumoniae 135(14.24%),Acinetobacter spp 131(13.82%),large intestine Egypt Greek bacteria 89(9.4%);Gram positive cocci 129(13.61%),the main pathogen was staphylococcus aureus and Fungi 203(21.41%),the main pathogen was candida albicans.Carbapenems was the most active antibiotics for gram negative bacill,and vancomycin for gram positive cocci.Conclusion Infectious bacteria have high selectivity to the sensitive antibiotics,and doctors should carefully use antibiotic according to the susceptibility test results in order to reduce hospital infection and the emergence and spread of resistant strains.

Objective To clarify the mechanisms of total saponins of panax ginseng (TSPG) in induction of apoptosis of K562 cells and to provide the theoretical basis and the experimental evidence for its clinical application. Methods The effects of TSPG on apoptosis of K562 cells were studied by morphometry, flow cytometry, morphological observation, and immunocytochemistry. Results The results indicated that TSPG could markedly inhibit the proliferation of K562 cells and induce the apoptosis of K562 cells. Our experiment also showed that after induction by TSPG, the ratio of positive K562 cells with Fas expression increased. Conclusion The mechanisms of TSPG in the induction of K562 cell apoptosis may be related to the increased expression of Fas in K562 cells.

ObjectiveTo summarize prenatal ultrasound image features of Cantrell′s syndrome (Cantrell′s pentalogy).MethodsFrom January 2007 to December 2013 in Shenzhen Maternity & Child Healthcare Hospital, there were twenty cases diagnosed and conifrmed by postmortem as Cantrell′s syndrome. The prenatal ultrasound image features and outcomes were analyzed.ResultsAmong the twenty cases, eighteen were singleton and two were twins with the other normal fetus. Prenatal ultrasound image: two obvious ultrasound image features of ectopic heart and hight omphalocele (seventeen cases) or gastroschisis (three cases) were appeared in prenatal ultrasound of twenty cases. Fourteen cases were complete ectopic heart (Ectopic heart was located within the omphalocele in one case, ectopic heart was completely exposed in amniotic lfuid in thirteen cases), six cases were incomplete ectopic heart, three cases were ventricular septal defect in which one was associated with pulmonary stenosis, two cases were single atrium and single ventricle in which one was associated with a single arterial trunk, one case was tetralogy of Fallot, and six cases were without signiifcant heart abnormalities. Associated with other abnormalities: seventeen cases were associated with other abnormalities in twenty cases, in which eleven cases were spinal abnormalities, nine cases were umbilical cord abnormalities (short umbilical cord in six cases, single umbilical artery in two cases, short umbilical cord associated with single umbilical artery in one case), ifve cases were neurological abnormalities (exencephalia in four cases, encephalocele in one case), four cases were limb abnormalities, three cases were cheilopalatognathus, one case was giant bladder. Three cases weren′t associated with other abnormalities. Nuchal Translucency: in eight cases, nuchal translucency were measured in early pregnancy. Nuchal translucency of ifve cases were thick, one case was cervical hygroma in one of the two twins. Chromosome examination results: only three cases had chromosome examination in twenty cases, in which one case was trisomy 21, another two were chromosome normal. Fetal outcome and examination results: in twenty cases, one of the two twins can′t survive after birth, and the other one of two twins was reduced in intrauterine, so the specimen could not be obtained. Eighteen cases of singleton underwent labor induction. The results of postmortem appearance (nineteen cases) and autopsies (ifve cases) were all consistent with prenatal ultrasound scan.ConclusionsEctopic heart and hight omphalocele or gastroschisis appearing at the same time was the characteristic of Cantrell′s syndrome in prenatal ultrasound and other abnormalities may be part of the Cantrell′s syndrome spectrum. It is beneift to detect and diagnose Cantrell′s syndrome by prenatal ultrasound in the ifrst trimester.

OBJECTIVE:To evaluate the effects of quality control circle(QCC)in improving the compliance of asthma/COPD outpatients handling inhaler devices. METHODS:By simple random sampling method,90 asthma/COPD outpatients receiving Tiotropium bromide powder for inhalantion,Salmeterol xinafoate and fluticasone propionate powder for inhalantion and Budesonide and formoterol fumarate powder for inhalantion were selected from our hospital during Apr. to Nov. 2015. The reasons for poor com-pliance of handling inhaler devices were analyzed by QCC. The countermeasures were formulated to improve the compliance,in-cluding clinical pharmacist education,follow-up,issuing education manuals,developing WeChat consulting. Operation step score of inhaler devices,compliance score and activity ability score of QCC members were analyzed statistically before and after QCC. RESULTS:After the development of QCC,operation step score of inhaler devices and compliance score in 90 asthma/COPD outpa-tients increased from 7.7 and 7.7 before activity to 8.8 and 9.3 after activity,the achievable rate of compliance was 114.3%,and the improvement rate was 20.8%. The sense of honor,responsibility,self-confidence,QCC techniques,communication and coordi-nation,team cohesion of all members were all improved obviously. CONCLUSIONS:QCC activity improves the compliance of asthma/COPD outpatients handling inhaler devices and shows the professional service level of clinical pharmacists,which is of sig-nificance to the improvement of pharmaceutical care.

Objective To comparatively analyze the advantages and disadvantages between a double immune-diffusion assay and a rate nephelometer analysis for the detection of antigen activity of pneu -mococcal capsular polysaccharides .Methods The antigen activity of pneumococcal capsular polysaccharides of serotypes 1,6B,9V,10A,14 and 19A from four manufacturers and ATCC were analyzed by a double im-mune-diffusion assay and a rate nephelometer analysis , respectively .The effects of antiserum samples and gain values on the rate response value were evaluated .Results The sample 4 of type 9V showed no antigeni-city with a rate response value similar to that of negative control as indicated by both tests .However ,the pre-cipitation lines and the rate response values presented by other polysaccharide samples differed in a wide range.Results of the rate nephelometer analysis were not affected by the anti -serum samples from different sources and the gain values .Conclusion The rate nephelometer analysis could quantitatively analyze the antigen activity of pneumococcal capsular polysaccharides .

Objective To investigate the effect induced by specific inducible nitric oxide synthase (iNOS) inhibitor 1 400 W on nasopharyngeal carcinoma CNE-2 cells lines and its mechanism.Methods CNE-2 cells were treated by different concentrations of 1 400 W,diamminedichloroplatinum (DDP),and both chemicals.Cell counting kit-8 (CCK-8) was used to examine the viability of cells.Quantitative realtime polymerase chain reaction (qRT-PCR) was applied to detect the iNOS mRNA expression.Results The expression of iNOS mRNA was down-regulated by 1400W and was positively correlated with inhibitionrate of cell proliferation.1 400 W inhibits proliferation of CNE-2 cell in a concentration-dependent manner.The proliferation inhibition rate of CNE-2 cells treated by 1 400 W combined with DDP was not enhanced.Conclusions Specific inducible nitric oxide synthase inhibitor 1 400 W can exerts anti-tumor effect though inhibiting the expression of iNOS mRNA;The mechanism of chemosensitization induced by iNOS inhibitor on CNE-2 cells may be closely related level of down-regulation of iNOS expression.
