Objective:To investigate the association of body weight and body mass index (BMI) with bone mineral density (BMD) and osteoporotic risk in elderly men with type 2 diabetes mellitus (T2DM).Methods:210 elderly male patients with T2DM admitted to the Department of Endocrinology of the First Hospital of Changsha from June 2017 to May 2018 were selected as the research objects. The height, weight and bone mass index (BMI) were measured. BMDs of the left hip [including femoral neck (FN), greater trochanter (G.T.), intertrochanter (InTro), and total hip (TH)] and lumbar spine (LS) were measured in 210 elderly male patients with T2DM by dual-energy X-ray absorption method. Patients were divided into three groups according to BMI: the overweight group (24.0 kg/m 2≤BMI<28.0 kg/m 2), the obesity (BMI≥28.0 kg/m 2) group, and the normal group (18.5 kg/m 2≤BMI<24.0 kg/m 2). The influence of body weight and BMI on BMD and osteoporotic risk in these elderly men with T2DM was analyzed. Results:The BMDs in various sites of the hip of the overweight group and obesity group were higher compared with those in the normal weight group ( P<0.05). There was a positive correlation between weight and BMI with BMDs in various sites of the hip femoral neck (including FN, G. T., InTro, and TH) ( r=0.239-0.427, P<0.05). All patients were divided into different tertiles (T1-T3) stratified by weight and BMI respectively. The BMDs in various sites of the hip increased with tertiles stratified by weight ( P<0.05). The TH-BMD also increased with tertiles stratified by BMI ( P<0.05). The odd ratios ( OR) were calculated using T3 as the control group and T1 as the case group, using T2 as the control group and T1 as the case group, respectively. The osteoporotic risks of T1/T3, T1/T2 at FN stratified by weight were significantly increased by 4.50 times ( OR=4.50, 95% CI: 1.41-14.35) and 9.27 times ( OR=9.27, 95% CI: 2.03-42.30); The osteoporotic risks of T1/T3, T1/T2 at TH were significantly increased by 3.25 times ( OR=3.25, 95% CI: 1.10-9.59) and 8.50 times ( OR=8.50, 95% CI: 1.85-38.99). The osteoporotic risks of T1/T3, T1/T2 at FN stratified by BMI respectively were significantly increased by 4.13 times ( OR=4.13, 95% CI: 1.28-13.25) and 5.58 times ( OR=5.58, 95% CI: 1.53-20.42); while the osteoporotic risks of T1/T3, T1/T2 at TH stratified by BMI were not significantly increased ( P>0.05). There was no statistically significant difference in BMDs and the osteoporotic risks of the LS among T1, T2, and T3, regardless of stratified by weight or BMI ( P>0.05). Conclusions:For elderly males with T2DM, weight and BMI are important factors affecting BMDs in the hip, and also affecting the osteoporotic risks of the hip, especially that of FN. Osteoporotic risks of the FN decrease with the increase of weight and BMI within a certain range.

Objective To investigate an economic and practical modality for the all-round rehabilitation of children with cerebral palsy(CP).Methods The six-in-one rehabilitation approach was designed according to the principal of modern rehabilitation and conductive education.It was mainly conducted through physical therapy,occupational therapy,speech therapy,sensory integration,supplemented with individual education and a self-originated "movement rehabilitation exercise".50 CP children were treated with this approach.Results After one period of treatment by six-in-one approach,the movement function,language ability and cognitive ability of those CP children improved tremendously.The children also got much progress in sociality and activities of daily living(ADL).The effective rate of rehabilitation reached 90%～96%.Conclusion The CP children have benefited variously in areas of language,movement,cognition,behavior,sociality and ADL from six-in-one approach,which requires small financial contribution from family and is cost-effective to the rehabilitation center.It is a new approach for all-round CP children rehabilitation,which can be adopted by small and middle sized rehabilitating institution and community rehabilitation,especially for those poor families CP children more than 3 years old.

OBJECTIVEThe relationship between latent adenovirus infection and airway inflammation have not been well documented. The aim of this study is to illustrate the roles of adenovirus E1A protein on the level of glutathione (GSH) in response to oxidative stress and the effect of the oxidant/antioxidant imbalance upon the transactivation of NF-kappaB triggered by E1A protein.

METHODSRat alveolar epithelial cell stably expressing adenoviral E1A or control plasmid were developed. For isolation of nuclear extracts, 5 x 10(5) cells were plated and grown overnight in 60 mm dishes. Experiments were repeated three times. The cell model of stably expressing adenoviral E1A was stimulated by H2O2. The level of GSH were measured. E1A positive clone was stimulated by LPS or TNF-alpha and treated with L-Buthionine-sulfoximine (BSO). The expression of NF-kappaB was measured by Western blot. Differences between groups were assessed for significance by Student' t test; multiple comparisons by the one-way ANOVA.

RESULTSThere is no difference of GSH level without stimulation between E1A-positive clones and E1A-negative clones. For E1A-positive clones, the level of GSH did not increase in response to H2O2 as E1A-negative clones. The quantitation by densitometry of the NF-kappaB expression in E1A-positive clones were (79.3 +/- 4.6), (80.3 +/- 3.8) respectively without treatment and were (81.8 +/- 3.9) - (89.9 +/- 1.6) and (94.1 +/- 1.9) - (99.8 +/- 1.6) respectively under LPS or TNF-alpha stimulation, which were significantly higher than that of the control group (68.3 +/- 3.8), (69.4 +/- 4.3) respectively without stimulation and (70.1 +/- 2.8) - (80.8 +/- 3.6), (73.4 +/- 4.9) - (83.2 +/- 6.7) respectively under stimulation. The quantitation by densitometry of the NF-kappaB expression in E1A-negative clones were (1.25 +/- 0.18) and (1.69 +/- 0.19) respectively under LPS and TNF-alpha-stimulation and (1.22 +/- 0.16) and (1.75 +/- 0.13) respectively upon treatment for LPS and TNF-alpha with BSO preincubation. There did not show difference upon treatment with LPS or TNF-alpha with or without BSO in E1A-negative cell clone. The quantitation by densitometry of the NF-kappaB expression in E1A-positive clone were (1.75 +/- 0.10) and (2.26 +/- 0.21) respectively upon treatment for LPS and TNF-alpha with BSO preincubation which were significantly higher than that of LPS or TNF-alpha-stimulation alone (1.35 +/- 0.12), (1.80 +/- 0.14) respectively.

CONCLUSIONThese results indicate that E1A protein decreased GSH levels in oxidant stress and upregulated NF-kappaB transcription activity. The oxidant/antioxidant imbalance in rat alveolar epithelial cells enhances E1A-modulated transcriptional activation of NF-kappaB. The mechanism underlying transactivation of NF-kappaB involved by E1A may be related to oxidative stress.

OBJECTIVETo study the effects of Jianpi Qingre Huayu Recipe in curing gastric ulcer and to preliminarily probe into its pathogenic mechanism.

METHODSFifty patients with gastric ulcer of Pi -insufficiency and stasis-heat syndrome type were assigned to the treated group (30 patients) and the control group (20 patients). They were treated respectively with JQH and Ranitidine. At the same time, another group consisting of 20 healthy persons was set up for normal control. The clinical effect on gastroscopic figure and traditional Chinese medicine (TCM) syndrome were observed. Changes of T-cell subsets and interleukin-8 (IL-8) in serum as well as IL-8 in mucosa around the gastric ulcer were determined before and after treatment by flow cytometry and ELISA.

RESULTSComparison of the total effective rate on gastroscopic figure in the treated group and the control group (86.7% vs 80.0%) showed insignificant difference, but the cure rate and markedly effective rate in the former (50.0% and 20.0%) was higher than that in the latter (40.0% and 15.0%) respectively. Comparison of the total effective rate on TCM syndrome in the treated group and in the control group (96.7% vs 70.0%) showed insignificant difference, but the cure rate and markedly effective rate in the former (63.3% and 23.3%) was higher than that in the latter (50.0% and 20.0%) respectively. Serum levels of CD3+, CD4+, CD8+ got restored to normal range in the treated group after treatment but it was not so in the control group. IL-8 level in gastric mucosa was improved in both groups but the improvement in the treated group was better.

CONCLUSIONJQH could effectively treat gastric ulcer and partly reduce its recurrence through improving patients' immune function.

OBJECTIVETo analyze the urinary cadmium, blood cadmium and urinary beta2-MG of workers in a zinc powder processing plant before and after the cadmium dust control, and to explore the effects of dust control on the prevention and treatment of cadmium hazards.

METHODSThe on-site occupational hazard survey was used to investigate the changes of urine cadmium, blood cadmium and beta3-MG of 84 workers exposed to cadmium before and after the treatment by self-control analysis for evaluating the effects of dust control measures in a zinc powder processing plant.

RESULTSAfter treatment of the cadmium dust, the geometric mean of zinc dust in the workplace significantly decreased from 3.38 mg/m3 to 2.22 mg/m3 (P < 0.01). The geometric mean concentration of blood cadmium [(2.19 +/- 1.19) microg/L] and urine cadmium [(1.96 +/- 0.74) microg/g Cr] before treatment were significantly higher than those of one year [(1.63 +/- 0.83) microg/L] and [(1.25 +/- 0.83) microg/g Cr] and two years [(1.36 +/- 0.95) microg/L] and [(0.94 +/- 0.72) microg/g Cr] after the cadmium dust control (P < 0.01), respectively. The positive correlations analysis between urine cadmium and blood cadmium concentration of one and two years before and after the cadmium dust treatment implied that there was significant difference (r = 0.466, P < 0.01).

CONCLUSIONDust treatment could reduce the impact of low concentration cadmium on the urine cadmium and blood cadmium concentrations of the workers exposed to cadmium, and effectively prevent the cadmium poisoning.
