Objective To discuss the adverse effect caused by capecitabine chemotherapy and its nuning measures.Methods A retrospective analysis was carried out for the adverse effect,occurrence regularity and nursing measures in 58 patients undergoing chemotherapy with capecitabine from June 2004 to December 2007.Results Handfoot syndrome happened in 30 cases,nausea and vomiting 23 cases,diarrhea 20 cases and stomatitis 15 cases in 58 patients.After positive prevention and effective nursing 57 patients successfully accomplished capecitabine chemotherapy.Only one patient withdrew due to grade 3 handfoot syndrome.Conclusions Positive prevention and eady detection and treatment can alleviate the adverse effect of capecitabine chemotherapy,so the psychological burden of patients can be relieved.

Tumor metastasis is a primary cause of leading to death of tumor patients,and difficult to control.The relationship between primary tumor(PT)and metastasis tumor(MT)is extremely complicated. Considerable animal experiments and clinical data confirm that treatment of PT encourages the growth of MT, but the mechanism is not still fully clear.Some studies show that the density depression of antiangiogenesis factor and immune escape of tumor cell are main reasons for MT accelerated growth.This article reviews the animal experiment,clinical observation and occurrence mechanism of primary tumor treatment promoting tu- mor metastasis.

According to the target-model of the health care system and characteristics of the health financing system,it is proposed in the paper that the charges of medical services should be the main revenue of public hospital compensation.Efforts should be made to adjust health care service prices and strengthen pharmaceutical management simultaneously so as to rebuild the structure of medical service charge.Medical insurance should make the majority in the compensation to cover most the medical expenses,with government subsidies supporting development.Both government financial investment and medical insurance should join their efforts for planning-guidance and performance-guidance.The authors also suggested to improve a graded and normative diagnoses and treatment system,regulate medical behaviors of public hospitals and their cost standards,justifying the total compensation and standard verification of such hospitals.

A stimulate method for determination of polybrominated diphenyl ethers ( PBDEs) and derivatives (OH-PBDEs and MeO-PBDEs), tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD) in egg samples was developed by gel permeation chromatography ( GPC) and dispersive solid phase extraction ( DSPE) combined with liquid chromatography tandem mass spectrometric ( HPLC-MS/MS) and gas chroma-tography-negative chemical ionization mass spectrometry ( GC-NCI/MS ) . The analytes were extracted with mixture of hexane and dichloromethane (1∶1, V/V) by accelerated solvent extraction (ASE), and purified by 100 mg C18 dispersive solid phase extraction ( SPE) sorbents followed with gel permeation chromatography (GPC) , and then analyzed by liquid chromatography tandem mass spectrometric (HPLC-MS/MS) and gas chromatography-negative chemical ionization mass spectrometry (GC-NCI/MS), respectively. The quantita-tion was carried out external standard method. The recoveries of objects were 64. 5%-97. 2% and 65. 6%-109 . 2% ( except BDE85 was 54 . 8%, OH-BDE-137 was 47 . 4%) spiked at 1 . 0 μg/kg or 5 . 0 μg/kg in egg white and egg yolk, respectively. The relative standard deviations (RSDs) were less than 20. 2%. The limits of quantitation (LOQ) for the object were 0. 01-0. 2 μg/kg.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.

Objective To evaluate the value of CK34?E12,p63 and P504S immunostaining in diag- nosis of benign and malignant lesions of the prostate.Methods Expression of CK34?E12,p63 and P504S in 74 benign and malignant lesions of prostate,including 27 PC,6 HGPIN,10 LGPIN,3 AAH and 28 BPH were observed by immunohistochemical method.Results Expression of p63 and CK34?E12 were positive in AAH,LGPIN and BPH,all of PC were negative,the positive rate of HGPIN was 83.3%(5/6).There were sig- nificant differences in p63 and CK34?E12 expression between PC and AAH,HGPIN,LGPIN,BPH(P

Objective Aortic arch obstruction is a commonly associated malformation in the patients with Taussig-Bing anoma- ly.Herein,we reported our outcomes of single stage corrections in patients with the Taussig-Bing anomaly associated with aortic arch obstruction.Methods Between May,2000 and Dec,2006,12 patients with Taussig-Bing anomaly associated with aortic arch obstr- uction (5 patients associated with interrupted aortic arch) underwent arterial switch operation with baffling of the left ventricle to neo- aorta.The corrections of aortic arch obstruction included extended resection combined with end to end anastomosis to aortic arch or end to side anastomosis to ascending aorta.Results The hospital mortality rate was 25% (3/12).The ventilating time and ICU stay were (7.4?2.1) days and (11.7?4.6) days,respectively.No reoperation because of residual anomalies was required.Conclusion Tanssig-Bing anomaly,especially associated with aortic arch obstruction,is different from transposition of great artery.The opti- mized operative indications,techniques and the managements of aortic arch obstruction are discussed in the article.

A multiplex real-time PCR was developed to detect ctxA of Vibrio cholerae, gyrB and tdh of Vibrio parahaemolyticus simultaneously. The multiplex real-time PCR were evalidated by detection for the three genes in 47 toxigenic V. cholerae O1 and O139 strains (ctxA+; O1=3, O139=44), 25 non-toxigenic V. cholerae strains (ctxA-; O1=12, O139=6, non-O1 and non-O139=7), 116 V. parahaemolyticus strains with or without tdh (73 or 43) and 9 other bacteria strains. The specificity and sensitivity of the multiplex real-time PCR in detection for the ctxA and the tdh genes in the strains tested were both 100.0%, compared to the results by routine PCRs. In the detection for V. parahaemolyticus specific gyrB using the multiplex real-time PCR, all of 116 V. parahaemolyticus strains were positive, and 9 other strains and 72 V. cholerae strains were all negative. The multiplex real-time PCR is a sensitive, specific and quick assay not only for detecting virulence genes of V. cholerae and V. parahaemolyticus but also for identifying V. parahaemolyticus at species level. In addition, two real-time PCRs for detection of V. parahaemolyticus virulence genes trh1 and trh2 were also developed.
