OBJECTIVE To lower the incidence of postoperative pulmonary infection in abdominal major operation.METHODS We performed a retrospective trial analysis on pulmonary infection after major abdominal operation in 402 cases from Oct 2004 to Oct 2005,and in the meanwhile effective preventive procedures were conducted.RESULTS Thirty three cases with pulmonary infection went weel with active treatment and nursing.CONCLUSIONS The predisposing factors for postoperative infection include anesthetic method,incision pain,and environmental pollution.The better methods for prevention of pulmonory infection are good preoperative instruction,planned respiration training,keeping airway confluent postoperatively,effectively reducing incision pain,infection control,and preventing environmental and air pollution.

OBJECTIVE To investigate the hospital infection rate and sites of patients in emergency intensive care(unit)(EICU),and provide basis for prevention and treatment of hospital infection.METHODS Patients who were hospitalized in EICU were investigated by retrospective study.RESULTS Among the hospital infection sites,(respiratory) tract was the most frequent one(65.63%),the next was urinary tract(28.13%),and the deep vein was the third(6.25%).The most common hospital infection bacteria were Staphylococcus aureus,Pseudomonas aeruginosa and Acinetobacter baumannii.CONCLUSIONS The analysis of the subjective and objective factors of hospital infection,and the acknowledge of relationship between nursing and hospital infection sites are(important) basis for hospital infection prevention and treatment.

Objective To observe the effect of early rehabilitation treatment at different time point on the motor function and activity of daily living (ADL) and emotion in acute stroke patients. Methods 120 patients with acute stroke were randomly assigned to three reha-bilitation groups and one control group according to the disease course (3 days, 5 days, 8 days when the disease is steady). Each group con-sisted of 30 eases. The patients in each group were treated with the regular medication therapy, rehabilitation groups were treated with com-prehensive rehabilitation treatment including Bobath technique therapy. Neurological deficit, motor function, balance function, ADL, emo-tion of all the patients were assessed before and 21 days after rehabilitation intervention. Results After treatment, the motor function, bal-ance function, ADL and emotion of each rehabilitation group were improved. The patients'rehabilitation scores in FMA, Fugl-Meyer balance function, MBI and HRSD got much better than that in control group. The difference was statistic significant. The effect of rehabilitation treat-ment did not show difference among rehabilitation groups. Conclusion Early rehabilitation treatment for acute stroke does benefit for stroke patients. Effect does not show vary with the start time of rehabilitation treatment within 8 days after acute stroke.

OBJECTIVETo observe the effect of total flavonoids of Oldenlendia difflusa (FOD) on NF-kappaB and IL-8, TNF-alpha, IL-10 expressions of ulcerative colitis (UC) model rats, and explore its immunological mechanism of anti-UC.

METHODSixty Kunming male mice with the average weight of (20 +/- 2) g were randomly divided into six groups. The control group (cont) was orally administered with distilled water. Whereas the remaining five groups were fed with 4% dextran sulphate sodium (DSS) solution for seven days to induce acute UC, and orally administered with the following drugs: distilled water (for the DSS group), SASP at dose of 500 mg x kg(-1) x d(-1) for the DSS + SASP group, FOD at dose of 60 mg x kg(-1) x d(-1) for the DSS + FOD-H group, FOD at dose of 40 mg x kg(-1) x d(-1) for the DSS + FOD-M group, and FOD at dose of 26.7 mg x kg(-1) x d(-1) for the DSS + FOD-L group. During the modeling and drug administration, the mice were scored for DAI. Seven days later, the mice were put to death, and their colonic tissue samples were collected to evaluate colonic mucosal lesions. The NF-kappaB p65, IL-8, TNF-alpha, IL-10 expressions were tested by immunohistochemical staining and ELISA.

RESULTSeven-day feeding with 4% DSS solution could successfully induce acute UC in mice. Compared with the cont group, the DSS group showed significantly higher DAI and colonic mucosal lesions, remarkable increase in NF-kappaB p65, IL-8, TNF-alpha expression in colonic tissues, and notable decrease in IL-10 expression (P < 0.05). FOD could prevent acute UC in mice included by DSS. Seven-day administration of 60 mg x kg(-1) x d(-1) or 40 mg x kg(-1) x d(-1) FOD could completely or partially resist the above mentioned changes caused by DSS. Compared with the DSS group, the DSS + FOD-H group and the DSS + FOD-M group showed reduction in colonic mucosal lesions, down-regulation in IL-8, TNF-alpha and NF-kappaB p65 expressions and up-regulation in IL-10 expression (P < 0.05).

CONCLUSIONFOD could significantly resist UC in mice. Its mechanism may be related to the inhibition of NF-kappaB p65 activation, the reduction of IL-8 and TNF-alpha expressions and the increase in the anti-inflammatory factor IL-10.

Due to its effect of systems regulation and promotion on body, Ginseng is always referred to be long-term used as a dietary supplement. But it was still unclear about its target of the tonic effects and also the side-effects long-term use may bring. Urine metabolomic method is suitable for long-term studies of pharmaco-dynamics, pharmacology and toxicology of traditional Chinese medicine because of its characteristics of non-invasive and monitoring the whole-body metabolism. This study was designed to detect the dynamic variation of rat urine metabolome along with a long-term administration of total ginsenosides using GC-TOF based metabolomic technology. Our result showed that either short-term or chronic administration of ginsenosides did not impact the rat urine metabolome significantly (as the PCA subgroup was not successful). By comparison, the short-term (1-3 w) dose of ginsenosides had the biggest metabolic influence including TCA cycle, catecholamines and neurotransmitter amino acids. Medium-term (6-10 w) dose had a gradually lower effect and long-term (27 w) dose almost had no effect. Our study indicates that both short and long-term administration of ginsenosides showed almost no obvious side-effect on the experimental animals.

OBJECTIVETo explore the effects of Huoxiang Zhengqi liquid (HXZQ) on enteric mucosal immune responses in mice with Bacillus dysenteriae and Salmonella typhimurium induced diarrhea (BSD).

METHODMice were randomly divided into four groups with 10 mice in each group: control group (control), BSD group, Huoxiang Zhengqi liquid treated BSD groups at high dosage and low dosage (HXZQ high, HXZQ low). HXZQ was administrated from the day of diarrhea induction at dosage of 5.21 g kg(-1) and 0.52 g kg (-1) respectively. Peyer's patch and periphery lymphocytes were prepared for flow cytometry, and level of TNF-alpha in periphery and enteric tissue homogenate were determined with ELISA. Student's t-test was used for statistics.

RESULTMice in BSD group started showing continuous diarrhea at the day of induction till the fourth day when the mice were sacrificed. Diarrhea in the mice of HXZQ high and low groups lasted for 36 and 54 h respectively. There were more CD4+ and CD8+ cells in periphery, less CD4+ cells in peyer's patch in BSD mice comparing to normal mice. In peyer's patch, there were more CD8+ cells in mice in HXZQ high and low groups and more CD4+ in mice in HXZQ high group. Higher level TNF-alpha in periphery and intestinal tissue homogenate in BSD group were observed. Mice in HXZQ high group showed the decreased level TNF-alpha in periphery and enteric tissue homogenate.

CONCLUSIONThe immune regulation on peyer's patch CD4+ and CD8+ cells and suppression on TNF-alpha level in enteric homogenate might partially explain the effect of HXZQ on improvement of BSD.

Objective A Real-time PCR method was established to study the infection of adenovirus (Ad) in infants with sporadic diarrhea in Wenzhou. Methods According to hexon gene of adenovirus, one prime pair was designed as universal primes and applied to detect adenovirus DNA by Real-time PCR. It was also compared with immunochromatographic assay. 157 fecal specimens from diarrhea infants were tested while positive specimens were sequenced and identified by isolate culture and restriction endonucleases. Results A rapid and specific Real-time PCR assay for detection adenovirns was set up. The positive rates of adenovirns in fecal specimens by immunochromatographic assay and Real-time PCR were 1.91% (3/157) and 3.18% (5/157), respectively. Out of the 154 specimens with negative result from immunochromatographic assay, 2 showed positive by Real-time PCR. 5 positive specimens, identified by Real-time PCR, were sequenced as Ad3 (3/157, 1.91% ) and Ad7 (2/157, 1.27% ). 2 of the 5 positive specimens were proved to be Ad3 by cell culture and restriction endonucleases.Conclusion Real-time PCR combined with sequence analysis seemed more sensitive and specific so could be used for identifying types of adenovirus in clinical specimens. Ad3 and Ad7 were important pathogens which caused infant sporadic diarrhea in Wenzhou during February and April in 2008.

Objective To investigate the distribution and antimicrobial resistance of clinical isolates derived from intensive care unit(ICU) pa-tients in China in 2012.Methods A total of 94178 non -duplicate clinical isolates from ICU of 557 tertiary hospitals were collected from January 2012 to December 2012.Antimicrobial susceptibility testing was carried out according to a unified using disc diffusion test ( Kirby-Bauer method ) or automated systems.The data were analyzed by WHONET 5.6 software according to Clinical and Laboratory Standards Institute ( CLSI) 2012 breakpoints.Results Among these 94178 non-duplicate clinical isolates, gram-negative organisms and gram-positive organisms accounted for 75.6% and 24.4%, respectively.The 5 most common pathogens in ICU were Acinetobacter baumannii ( 15.8%) , Klebsiella pneumoniae ( 14.7%) , Pseudomonas aeruginosa ( 12.8%) , Escherichia coli ( 12.5%) and Staphylococcus aureus (8.5%).Methicillin -resistant Staphylococcus aureus ( MRSA ) strains and coagulase -negative Staphylococcus ( MRCNS) accounted for 57.5% and 83.7%, respectively.However, 69.2% of Staphylococcus aureus strains were still susceptible to trimethoprim -sulfamethoxazole, while 83.9% of CNS strains were susceptible to rifampin.No Staphylococcus aureus strain was resistant to vancomycin, teicoplanin and linezolid.2.1% of the CNS strains were found resistant to teicoplanin.The resistant rates of Enterococcus faecalis and Enterococcus faecium to vancomycin, teicoplanin and linezolid were 1.8%, 3.1%,2.3% and 5.9%,5.9%1.4%, respectively.Extended spectrum β-lactamases ( ESBLs)-producing strains accounted for 67.5%, 45.4%, 32.5%and 39.5%in Escherichia coli, Kleb-siella pneumoniae, Klebsiella oxytoca and Proteus mirabilis, respectively.Overall, 2.2%-10.4%of the Enterobacteria-ceae strains were resistant to carbapenems.The resistance rates of Acinetobacter baumannii to imipenem and meropenem were 70.8 and 69.2%, respectively.The resistance rates of Pseudomonas aeruginosa to imipenem and meropenem were 38.5%and 37.4%, respectively.Conclusion Bacterial resistance is still an serious problem in ICU in China, espe-cially the carbapenem resistant Enterbacteriaceae and Acinetobacter baumannii.It is mandatory to take effective hospital infection contral measures and rational use antibiotics.
