Objective To investigate the role of the clock gene promoter methylation in aging. Methods C57BL mice of 4- (young, n=9) and 20- (old, n=10) month-old were determined the promoter methylation level of clock genes (Per1/2, Bmal1/2, Cry1/2, Clock, Npas2) in the stomach, spleen, vascular, kidney and striatum with methylation-specific polymerase chain reaction (MSP). Results The incidence of promoter methylation of Cry1, Bmal2 and Npas2 in spleen increased in old mice (P<0.05), while the promoter methylation of Per1 in stomach decreased (P<0.05), and the promoter methylation of Bmal1 in vascular increased (P<0.05). Conclusion Promoter methylation of some clock genes is involved in process of aging in a tissue-specific way.

Human lymphocyte function-associated antigen 3 (hLFA3) has been identified as an important T cell accessory molecule. Rhesus monkeys (Macaca mulatta) have been widely used as animal models for human immune disorders. Due to the species-specificity of immune system, it is necessary to study M. mulatta LFA3 (mmLFA3). In this study, the gene encoding mmLFA3 CD2-binding domain (mmLFA3Sh) was amplified by polymerase chain reaction (PCR) and genetically fused to human IgG1 Fc fragment in pPIC9K to construct the expression plasmid pPIC9K-mmLFA3Sh-Ig. Approximately 3-4 mg mmLFA3Sh-Ig protein was recovered from 1 L of inductive media, and mmLFA3Sh-Ig produced by the P. pastoris can bind to the CD2 positive cells, and suppress the monkey and human lymphocytes proliferation induced by Con A and alloantigen in a dose-dependent manner. These results suggested that mmLFA3Sh-Ig might be used as a novel tool for pathogenesis and experimental immunotherapy of Rhesus monkey immune disorders.

Objective To study and estimate the effective dose of interventional employees in the common cerebralvascular, cardiovascular and liver interventional diagnosis and treatment.Methods The absorbed doses of tissue or organ of anthropomorphic phantom in these three procedures were estimated by the anthropomorphic phantom experiment.The effective doses were calculated by the tissue weight factor which was given by International Commission on Radiological Protection publication 103.Results The effective doses to high, medium and low group were 24.0, 9.7,6.8 μSv for cerebralvascular interventional diagnosis and treatment, and 36.3, 29.3, 17.8 μSv for cardiovascular interventional diagnosis and treatment, and 23.9, 11.3, 5.5 μ Sv for liver interventional diagnosis and treatment, respectively.Conclusions The effective doses of high, medium and low group of interventional employees in cardiovascular interventional procedure are higher than those of cerebralvascular and liver interventional procedures.

Objective To study whether the uremic toxins accumulated long-term in uremia patients may be involved in oxidation of protein by forming advanced oxidative protein products (AOPPs). Methods Malonylaldehyde (MDA), hippuric acid (HA) and p-cresol were used as the representatives of uremic toxins. Human albumin serum (HSA), plasma specimens from normal or uremia patients were incubated respectively with MDA (10 retool/L), HA (20 mmol/L) and p-cresol (10 retool/L) or PBS (20 retool/L, pH 7.4, as control groups) at 37℃ for 30 minutes or 24 hours, respectively. Those indices such as AOPPs, protein thiol groups (Pt-SH) and dityrosine were used as biomarkers of protein injury. High performance liquid chromatography (HPLC) was employed to identify the aggregation and cross-links of modified proteins. Results AOPPs levels in all groups containing poison compounds were significantly increased by 121.5%(P<0.05) compared to that in control groups. Uremic toxins also resulted in over 14.7% loss in Pt-SH (P< 0.05) and 119.2% increment in dityrosine, respectively (P<0.05). Meanwhile, the formation of HMW-AOPPs in a time-dependent manner was observed by HPLC and cross-linked protein levels were significantly increased by 148.45%~333.3% in comparison with control groups. Conclusion Uremic toxins can directly mediate the damage of proteins by inducing the formation of HMW- AOPPs in a time-dependent manner, which is also one of the mechanism of AOPPs production in vivo besides the activation of the myeloperoxidase-H2O2-Cl pathway.

Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

PurposeTo explore the relationship between expression of apoptosis-modulating proteins and chemotherapeutic efficacy in acute leukemia. MethodsImmunocytochemical method was used to detect the expression of Bcl-2、Bcl-XL、Bax and Bak in 36 cases of acute leukemia including previously untreated/ drug-sensitive group and refractory/relapse group. ResultsThe average positive cell rates of Bcl-2 and Bcl-XL in refractory/relapse group were (41.68 ± 14.39) % and (35.96 ± 9.95 ) %, while the rates in previously untreated/drug-sensitive group were (15.64 ± 8.51 )% and (12.91 ± 8.63 )%. Statistical analysis showed the average positive cell rates of Bcl-2 and Bcl-XL in refractory/relapse group were higher than those in previously untreated/drug-sensitive group (P < 0.01 ). There was no significant difference in average positive cell rates of Bax and Bak between refractory/relapse group (25.28 ± 15.49) %, (15.53 ± 10.64) % and previously untreated/drug-sensitive group (21.55 ± 12.58)%, (13.23 ± 8.36)%. The Logistic regression of expression of Bd-2 、Bcl-XL、Bax and Bak to complete remission rate (CR) of 36 cases of acute leukemia showed that Bcl-XL was the most risk factor in reducing the CR.ConclusionsBcl-2 and Bcl-XL might play important roles in multi-drug resistance of acute leukemia and Bcl-XL was more important than Bcl-2.
