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 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 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 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 detect the impact of reactive oxygen species ( ROS) on mitochondrial morphology and distri-bution during mitosis.Methods A viral vector in which the fluorescence gene was specifically under the control of mito-chondrial promoter was constructed and confirmed through DNA sequencing and Western blotting.After transfecting HeLa s3 cell with packaged virus, the HeLa s3-COX4tp-EGFP cell line stably expressing the mitochondrial fluorescence signal was obtained.With immunofluorescent staining, the impact of ROS on the morphology and distribution of mitochondria dur-ing mitosis was inspected.Result The cell line constantly expressing mitochondrial fluorescence signals was successfully constructed.Meanwhile,it was found that H2 O2 treatment could significantly change the morphology and distribution of mi-tochondria during mitosis by confocal microscopy.Conclusion Our study demonstrates that ROS can affect the morphology and distribution of mitochondria during mitosis.This research help study the relationship between the mitochondrial function and the regulation of mitosis in the future.
