Objective To study the status and influencing factors on drug therapy compliance for the spinal tuberculosis patients after leaving hospital, so as to advance the corresponding nursing intervention strategies and to consolidate the cure effect. Methods 168 spinal tuberculosis patients in community were investigated by the basic information schedule table, compliance with regular treatment schedule table, the degree of disease cognition questionnaire, and the social support questionnaire. All questionnaires were collected and statistically treated. Results The scores of drug therapy compliance for the spinal tuberculosis pateints after leaving hospital were in a lower level, and the rate of compliance with regular treatment for spinal tuberculosis patients was 46.8%. The drug therapy compliance was affected by the years of age, the degree of disease cognition, the adverse reaction of medicine, the economy condition, the degree of civilization and the degree of social support (P <0.05). The drug therapy compliance was positively correlated with the degree of disease cognition, the economy condition, the degree of civilization and the degree of social support. The drug therapy compliance was negatively correlated with the years of age and the adverse reaction of medicine. Conclusions The druy therapy compliance for the spinal tuberculosis patients out of hospital is generally in a lower level Nursing stuffs should adopt active nursing interventions to raise the drug therapy compliance for spinal tuberculosis patients based on the influencing factors.

BACKGROUNDBlocking the 4-1BB/4-1BB ligand (4-1BBL) signal may modulate the secretion of Th1/Th2 cytokines and prolong the survival of the grafts, which play a key role in organ transplantation tolerance. The aim of this study was to investigate the role of blockade of the 4-1BB/4-1BBL co-stimulatory pathway with 4-1BBL monoclonal antibody (mAB) in acute rejection of rat orthotopic liver transplantation.

METHODSThe orthotopic liver transplantation model was set up, while male Lewis rats were used as liver donors and Brown-Norway rats as recipients. The recipient rats were intravenously injected with anti 4-1BBL mAB or isotype control antibody. Groups were monitored for graft survival after transplantation. Plasma chemistry, including aspartate transaminase (AST), alanine aminotransferase (ALT), and bilirubin (BIL), was assayed. The concentrations of interleukin (IL)-2, IL-10 and interferon (IFN)-gamma in plasma were also measured by enzyme-linked immunosorbent assay. Allograft histology images were collected under light microscope and electron microscope.

RESULTSIsotype antibody treated recipients exhibited elevated plasma levels of liver injury markers including AST, ALT and BIL, progressive portal and venous inflammation and cellular infiltration of the liver allografts, and a mean graft survival time (MST) of 10.9 days. Administration of anti 4-1BBL mAB resulted in a decrease in plasma levels of liver injury markers and the concentrations of IL-2, IL-10 and IFN-gamma. The histological grade of rejection on day 7 decreased and MST (17.3 days) increased substantially.

CONCLUSIONSThese results demonstrate that attenuation of acute rejection follows the blockade of the 4-1BB/4-1BBL co-stimulatory pathway with 4-1BBL monoclonal antibody and strongly suggest it is a promising strategy to prevent progression of graft rejection by suppressing T cell-mediated immunity.

BACKGROUNDThe antitumor role of Ras association domain family 1A (RASSF1A) gene and its potential molecular mechanisms are not well understood. The objective of this study was to observe the antitumor ability of RASSF1A in hepatocellular carcinoma, and study the mechanisms of cell apoptosis induced by RASSF1A.

METHODSAfter stably transfecting a RASSF1A (wild-type or mutant) expression vector into the BEL-7402 hepatocellular carcinoma cell line, RT-PCR and Western blotting was used to detect the RASSF1A expression levels in recombinant cells. The effects of wild-type RASSF1A on cell growth were observed in vitro by analyzing cell proliferation rate, cell colony formation, and in vivo by analyzing tumorigenesis in nude mice. In addition, the effect of RASSF1A gene expression on the chemosensitivity of human hepatocellular carcinoma cells to antitumor drugs was examined by inhibition of cell proliferation and the percentage of apoptotic cells.

RESULTSWild-type RASSF1A, not the mutant, suppressed cell growth in vitro and in vivo. Re-expression of wild-type RASSF1A could enhance the inhibition of cell proliferation and the percentage of apoptotic cells following cell treatment with mitomycin, but had no significant effect when combined with adriamycin, etoposide, 5-fluorouracil and cisplatin treatment.

CONCLUSIONWild-type RASSF1A inhibits cell growth and enhances cell chemosensitivity to mitomycin in hepatocellular carcinoma, suggesting that RASSF1A may serve as a new target for gene therapy in hepatocellular carcinoma patients.

OBJECTIVETo study the application value of asthma predictive index (API)-based group therapy in wheezing children under 5 years of age.

METHODSA total of 239 wheezing children under 5 years of age were divided into API-positive (n=126) and API-negative groups (n=113). Each group was randomly assigned to inhaled corticosteroids (ICS) subgroup and montelukast sodium (leukotriene receptor antagonist, LTRA) subgroup. The ICS and LTRA subgroups received the same drug therapy at the same dosage within the first four weeks of treatment. In the stable period of disease, the ICS subgroup only received aerosol inhalation of budesonide suspension, while the LTRA group was orally given montelukast sodium only. Asthma symptom scores were assessed and recorded at different time points.

RESULTSIn the first four weeks of treatment, ICS and LTRA were effective both in the API-positive and API-negative groups; the two groups showed significant improvements in asthma symptom scores, and the asthma symptom score showed no significant difference between the ICS and LTRA subgroups of each group. After 24 weeks of treatment, the two therapies were still effective; in the API-positive group, the LTRA subgroup had a better treatment outcome than the ICS subgroup, but there was no significant difference in treatment outcome between the LTRA and ICS subgroups of the API-negative group.

CONCLUSIONSFor wheezing children under 5 years of age, therapeutic strategies can be chosen based on API in the stable period of disease, so as to better control wheezing.

Objective To investigate the prognostic sequelae in neontes with hypoxic-ischemic encephalopathy (HIE) and ven-tricnlar dilatation.Methods Seventy-six full term newborns infants with HIE were followed up at the age from 3 to 19 months after therapy. Twenty-five infants among them were followed up by telephone in the epidemic period of SARS.Results Among 76 infants of 88 newborn infants with HIE(84.6%), 73 infants were normal (96.1% ). 1 infant had cerebral palsy (1.3%), 2 infants died (2.6 %).Among 39 cases with mild HIE, none of them had cerebral sequelae; among moderate HIE. 1 infant had cerebral palsy (2.9%) 1 infant died (2. 9 %), interlenkin-4 among severe HIE 50 % died (P00.5 The poor outcome of HIE in those infants were related to intrauterine growth retardation,severe birth asphyxia;and inadequate treatment.Cranial ultra-sonography of 49 infants were done on follow-up,and 12 of them (24.5 % ) had ventricular dilatations, which appeared after birth with 6 infants. Others occurred on follow-up with 1 infant had cerobral palsy,all ventricular dilatations recovered to normal at 12- 19 months except the cerebral palsy.Conclusions The poor outcome of HIE depends on the infants with intranterine growth relarda-tion,severe birth asphyxia and inadequate treatment.The prognosis of transient ventrealar ddatation are good except cerebral palsy.J Appl Clin pediatr,2004,19(12) : 1045- 1047

Objective To investigate the cytoprotection and mechanism of carbachol(CCH)to stimulate M3mus-carinic acetylcholine receptor(M3-mAChR) against hypoxia injury induced by cobaltous chloride hexahydrate (CoCl2) in rat cardiomyocyte line H9c2. Methods Select the normal rat cardiomyocyte line H9c2 as the control group, rat cardiomyocyte line H9c2 was managed with CoCl2to develop hypoxia injury model, M3-mAChR spe-cific agonist CCH and antagonist 4-diphenyl-acetoxy-N-methyl-piperidine methiodide(4-DAMP) were used for in-tervention. The cell viability was tested by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT); The apoptosis in cardiomyocyte was detected by flow cytomery(FCM); The expression of M3-mAChR,caspase-3, HIF-1α and HO-1 proteins was measured by Western blot assay. Results In hypoxia group,the ap-optosis rate was significantly increased while cell proliferation decreased, the expression of HIF-1α, caspase-3 and HO-1 proteins were up-regulated obviously;After treatment with CCH,the apoptosis and cell proliferation of cardiomyocytes were significantly decreased, while the proliferation of cells increased, and the expression of M3-mAChR, HIF-1α and HO-1 proteins increased, the expression of caspase-3 protein was significantly decreased. Moreover, when applying 4-DAMP as intervention, these effects mediated by CCH was abolished.Conclusions CCH stimulates M3-mAChR against hypoxia injury induced by CoCl2in rat cardiomyocyte strain H9c2, and the mechanism may be related to down-regulation of caspase-3 expression and up-regulation of HIF-1α and HO-1 protein expression.
