0.05).Neither pruritus nor respiratory depression was noted in both groups.CONCLUSION:At an equivalent dose,Nefopam Hydrochloride showed a similar PCSA efficacy to Fentanyl after surgery but less side effect,therefore,it can be applied in postoperative PCSA.

Objective To investigate the influence of systematic health education on the disease cogni-tion and behavior of treatment compliance in patients with infectious diseases. Methods Patiens with infec-tious diseases in our department were divided into the control group(142 patients) and the experimental group (136 patients). The control group received common health education, the experimental group was given addi-tional knowledge education about infectious disease based upon routine education. The two groups were inves-tigated before and after intervention by adopting self-designed investigation scale.The cognition rate of disease and the rate of behavior of treatment compliance were compared by χ2 test. Results The cognition rate of disease and the rate of behavior of treatment compliance in the experimental group were higher than those of the control group. Conclusions Systematic health education can not only increase degree of disease cogni-tion but also improve behavior of treatment comphanee in patients with infectious diseases.

AIM To study if the activated T lymphocytes induced by hepatocellular carcinoma (HCC) rejection antigenic peptide SLIVHLNEV (mutant peptide of C met) pulsed dendritic cells (DCs) can provide protection against tumor challenge in nude mice HCC model and in vitro . METHODS SLIVHLNEV was eluted from HCC cell line HHCC by mild acid buffer and was identified by the mass spectrometry technique. SLIVHLNEV pulsed DCs isolated from HLA A2+ ruptured spleen were co cutured with isogeneic T lymphocytes. Cytotoxicity was tested using lactate dehydrogenase (LDH) release assay. The induced cytotoxic T lymphocytes (CTLs) were implanted into nude mice in order to protect them against transplanted HHCC tumor cells. The inhibition effect of CTLs on the growth of implanted tumor in nude mice was also observed. RESULTS The CTLs induced by SLIVHLNEV pulsed DCs had unique ability to kill HHCC tumor cells in vitro. They also protected the nude mice against the further challenge of HHCC tumor cells and inhibited the growth of implanted tumor. CONCLUSION DC based HCC rejection antigenic peptide SLIVHLNEV vaccine can induce powerful immune reaction both in nude mice HCC model and in vitro.

Objective To investigate the effects of lipopolysaccharide(LPS) on the tryptophan-kynurenine(TRP) metabolic pathway in rat brains and provide new evidence for the relationship between inflammation and depression.Methods Rats in LPS group were given a single dose of 3.5 mg/kg LPS.while the rats in control group were given the same dosage of saline.The dialysis in ventro-hippocampus were collected by microdialysis within 8 hours and then the TRP,KYN and KA were detected by LC-MS/MS.And the expression of indoleamine 2,3-dioxygenase was detected by Western-blot.Results The level of TRP((550.15± 107.96) pmol/L) and KYN ((337.95±62.73) pmol/L) showed a time-dependent increase after administration LPS 4 h compared with the control group(TRP (368.38±59.31) pmol/L,KYN (172.80±43.96) pmol/L),while KA level in the circulation exhibited a trend to decrease,especially at 7 h ((3.47±0.62) pmol/L,P＜0.05).The ratio of KYN/TRP significantly increased at about 5 h (0.69±0.11,P＜ 0.05),and an ratio of KA/KYN (0.02±0.00) was dramatically decreased after administering LPS 4 h compared with the control group (0.05±0.01)(P＜0.05).Most of the analytes showed more dramatic changes around 4 h to 8 h.LPS group(1.48±0.37) increased the protein expression of indoleamine 2,3-dioxygenase compared with the control group(1.00±0.24) (P＜0.01).Conclusions LPS may cause tryptophan metabolic abnormalities and accelerate the way of kynurenine metabolism,leading to decreased the kynurenic acid status.

Objective To evaluate the clinical and imaging features of the sellar region lesions in children.Methods The clinical and imaging features of 112 cases with sellar region lesions were analyzed retrospectively,which were confirmed by pathology.Results 37 cases were craniopharyngiomas, which had two main symptoms of intracranial hypertension(57%)and diabetes insipidus(11%).On imaging it demonstrated as a calcified cystic tumor(81%).18 cases were gliomas, the main clinical feature of which was decreased visual acuity,13 of them were pilocytic astrocytoma, which manifested as a solid tumor with significantly enhancement(94%).16 cases were germ cell tumors,the main complaint was diabetes insipidus (75%),13 of them were germinoma, which showed iso-high density on CT and moderate enhancement after administration of contrast.And it showed high signal intensity on DWI.7 cases were hamartoma,86% patients of which showed gelasmus epilepsy,the imaging showed iso-signal masses with no enhacement in the hypothalamic papillary region.5 cases were LCH,80% of which had the complaint of diabetes insipidus,imaging findings manifested as thinkened pituitary stalk and loss of hyperintensity of posterior pituitary on T1WI.3 cases were pituitary tumors.23 cases were Rathke's cleft cysts,3 cases were arachnoid cyst.Most of the patients presented with headache.Conclusion The clinical and imaging features shows some specific features, which is helpful to improve the correct rate of diagnosis and provide the basis for further treatment.

100 u/L 24 months later and another 38 year-old patient underwent surgical operation of ovaries bilaterally before UAE. Conclusions Temporary amenorrhea may not mean ovarian dysfunction or failure. The probability of ovarian dysfunction or failure after UAE is low, which mainly occur in the peirmenopausal patients. Consideration of the probability of inducing early ovarian failure, caution should be taken for UAE on the patients having ovarian surgery before. (J Intervent Radiol, 2006, 15: 472-475)

Objective To investigate the drug resistance,source and molecular epidemiology of methicillin-resistant Staphyloccus aureus(MRSA)causing nosocomial infection. Methods Fifty-seven pathogenic MRSA strains were isolated from Beijing Tongren Hospital during 2007 and 2008.K-B method,MIC assay,multiple PCR,automatic repetitive element sequence-based PCR(REP-PCR)typing platform and DL MRSA Library were used to identify the resistant phenotypes,Panton-Valentine leukocidin gene (pvl)and REP-PCR types of the MRSA.Results All strains were classified as 6 antibiotic resistant phenotypes(a-f)based on the resistance to rifampin,clindamycin,levofloxacin and cotrimoxazole.The MRSAs with Staphylococcal cassette chromosome mec(SCCmec)Ⅲ and SCCmec Ⅱ accounted for 91.23% (52/57)and 5.26%(3/57)of all strains,respectively.Only one strain was pvl positive.All strains were typed as REP-A-F(6 types)and three single clones by automatic REP-PCR typing platform,in which REP-C was predominant(30/57,52.63%).Three out of 6 REP-D strains were from laryngology wards.The REP-C-SCCmec Ⅲ were genetically most close to the Brazilian clone-SCCmec Ⅲ in DL MRSA Library.Conclusion s REP-C-SCCmec Ⅲ-a type are the major epidemic hospital-associated MRSA and the REP-D-SCCmec Ⅲ-d is usually isolated from patients received laryngeal surgery. Automatic REP-PCR typingplatform combined with DL MRSA Library database is an effective approach to study the nosocomial infection.

[Objective] To investigate the expression of NF-κB and IL-lra in gastric cancer, and to explore their correlation with the clinicopathological parameters and prognosis of gastric cancer (GC). [Methods] Expression of NF-κB and IL-1ra was detected by immunohistochemistry in tissue microarry of 359 cases of GC. [Results] The expression rates of NF-κB in the patients with metastasis of lymph node, TNM Ⅲ-Ⅳ stage, and poorly differentiated of histology were 80.2%, 80.0%, and 79.2%, respectively. The expression rates of IL-1ra in the patients with tumor size ≤3 cm, early stage, non-metastasis of lymph node, and TNM Ⅰ-Ⅱ stage were 61.7%, 75.0%, 66.4%, and 61.9%, respectively. The 5-year survival rate of the cases with non-expressed NF-κB was statistically higher than that of the cases with expressed NF-κB(P=0.036). The 5-year survival rate of the patients with negative expression of NF-κB and positive expression of IL-1ra was statistically higher than the others (P=0.021). [Conclusions] NF-κB is the adverse predictors of prognosis of gastric cancer. IL-1ra maybe play a protective role in early gastric cancer stage, but it is necessary to study deeply and get more evidences.

Objective To investigate the effect of methylene blue(MB)on liver ischemia-reperfusion (I/R) injury in rabbits.Methods Twenty-four healthy New Zealand white rabbits of both sexes welshins 2.0-2.3 kg were randomly divided into 3 groups (n=8 each):group Ⅰ sham operation(group s);group Ⅱ I/R and group Ⅲ methylene blue (group MB).The animals were anesthetized with intravenous 2% pentobarbital 30 mg/kg.Liver I/R was produced by occlusion of hepatic blood flow for 40 min followed by 60 min repeffusion.In group MB methylene blue 5 mg/kg was injected iv at 20 min before liver ischemia.Femoral artery was carmulated for MAP monitoring and blood sampling.MAP and HR were recorded immediately before(T1,baseline)and at 20 and 40 min of ischemia (T2,3) and 1,5,30,60 min(T4-7)of repedusion.Blood samples were collected at T1,T5,T6 and T7 for measurement of seruln TNF-α and IL-6 concentrations.Plasma AST and ALT activities were measured at T1,T6 and T7.Liver specimens were obtained at the end of experiment for determination of SOD activity and MDA content.Results In group I/R MAP was significantly decreased at T4-7 during reperfusion and HR at T7 as compared with the baseline at T1;while in group MB no significant change in MAP and HR Was observed during ischemia and reperfusion as compared with the baseline.The gerum TNF-α and IL-6 concentrations and the plasma ALT and AST activities were significantly increased during reperfusion as compared with the baseline immediately before ischemia in group I/R and MB and were significantly lower in group MB than in group. I/R. The SOD activity was significantly higher while MDA content was significantly lower in group MB than in group I/R. Microscopic examination showed that liver damage was less severe in group MB than in group I/R. Conclusion The administration of MB can maintain hemodynamic stability and attenuate liver I/R injury in rabbits.
