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.

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.

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.

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.

OBJECTIVETo analyze the molecular basis for an individual with ABx09 phenotype of ABO subtype.

METHODSThe ABO group antigens on red blood cells of the proband were identified by monoclonal antibodies, and the ABO antibody in serum was detected by standard A, B, O cells. The exons 1 to 7 of ABO gene were amplified by polymerase chain reaction (PCR) respectively and the PCR products were sequenced directly. The amplified products for exons 5 to 7 were also cloned by TOPO TA cloning sequencing kit to split the two alleles apart, selected colonies were sequenced bidirectionally for exons 5 to 7 of the ABO gene. The samples of the proband's parents were collected, then serological test of the blood group and sequence analysis for exons 6 and 7 of ABO gene were preformed.

RESULTSBoth A and B antigens were detected on red blood cells of the proband and there was anti-B antibody in the serum. There was no G deletion at position 261, while 297AG in exon 6, 467CT, 526CG, 657CT, 703GA, 796CA, 803GC, 889GA and 930GA heterozygote in exon 7 were detected by direct DNA sequencing, which can be assigned for A102Bx09 genotype. After cloning and sequencing, two alleles A102 and Bx09 were obtained. The sequence of Bx09 had one nucleotide changes (G to A) at position 889 compared with that of B101, which resulted in an amino acid change of Glu to Lys at 297 position. The Bx09 in the proband was inherited from her mother by family investigation.

CONCLUSIONG to A at nt889 of alpha-1,3 galactosyltransferasegene can result in Bx09 phenotype, with the presence of anti-B antibody in serum.

OBJECTIVETo study the changes of pharmacokinetics of 6,7-dimethoxycoumarin in a rat model of alpha-naphthylisothiocyanate (ANIT)-induced experimental hepatic injury after oral administration of Yinchenhao Decoction (, YCHD) using an ultra pressure liquid chromatography (UPLC) method.

METHODSRats were divided into a normal group and a model group, after modeled by 4% ANIT (75 mg/kg) for 48 h, they were orally administrated with YCHD extract at the dose of 0.324 g/kg, and then blood was collected from their orbital sinus after different intervals. Changes in liver function were monitored by the levels of liver enzymes [alanine aminotransferase (ALT), aspartate aminotransferase (AST)] and bilirubins [total bilirubin (TBIL), direct bilirubin (DBIL)], the concentration of 6,7-dimethoxycoumarin in plasma were measured by UPLC, and the pharmaceutical parameters were calculated with DAS2.1.1 software.

RESULTSThe concentration-time curve of both normal and modeled rats after oral administration of YCHD was obtained. Their time to maximum plasma concentration (t(max)) were both 0.25 h, the maximum concentration (C(max)) were 4.533 μg/mL and 6.885 μg/mL, and their area under concentration-time curve (AUC)(0→24h) were 16.272 and 32.981, respectively. There was a 51.88% and 100.46% increase in C(max) and AUC(0-t) (P<0.05), but there showed a 45.52% and 92.93% reduction in clearance of drug and volum of distribution (P<0.05), respectively.

CONCLUSIONSHepatic injury could significantly influence the pharmacokinetics of 6,7-dimethoxycoumarin after oral administration of YCHD, the absorption and distribution process was accelerated in liver injured rats, but the metabolism and elimination process was slowed. And this may lead to a significant accumulation of 6,7-dimethoxycoumarin in the body.
