Objective In order to provide scientific evidence for revealing the pathophysiological changes, levels of the humoral and cellular immunity and cytokines in elderly patients with bacterial pneumonia were determined. Methods The changes of immunological markers including IgA, IgG, IgM,C3, C4,T cell subpopulation (CD3 +, CD4 +, CD8 +) and CD4 +/CD8 +, IL 2, IL 6, IL 8, TNF ? were examined for the elderly bacterial pneumonia group(BPG), the aged control group(ACG) and the young control group(YCG). Results The level of CD3 +〔(53 90?7 10)% vs (62 67?6 08)%〕, CD4 +〔(33 85?4 69)% vs (3 57?3 40)%〕, IL 2〔(4 09?0 69) ?g/L vs (6 72?0 52) ?g/L〕 and IL 8〔(0 28?0 07) ?g/L vs (0 39?0 09) ?g/L〕 in ACG were significantly lower than those in YCG. The levels of IgA, IgG, IgM, C3, CD8 +, IL 8〔(0 33?0 08) ?g/L vs (0 28?0 07) ?g/L〕, and TNF ?〔(1 25?0 23) ?g/L vs (1 10?0 20) ?g/L〕in BPG were significantly higher than those in ACG; and in BPG the levels of IgG, IgM, C3, IL 8 and TNF ? were significantly higher than those in YCG. However, the levels of CD3 +, CD4 + and the ratio CD4 +/CD8 +in BPG were markedly lower than those in YCG;the IL 2(2 730?0 612 ?g/L) was much lower than that of ACG〔(6 72?0 52) ?g/L〕 and YCG〔(4 09?0 69) ?g/L〕, respectively. Conclusions The occurrence and the progress of bacterial pneumonia in the elderly are related to the immunological functioning including the excessive humoral immunity, the super activation of complement system, the dysequilibrium of T cellular immunoloregulation network and the super excretion of inflammatory cytokines.

Objective To investigate the feasibility of achieving consistent image quality with dose reduction technology in lumber spine MSCT examination with Z-axis automatic tube current modulation (ATCM). Methods Forty-eight patients diagnosed as lumber intervertebral disc protrution scanned twice by MSCT before and after interventional operations with the same coverage from third lumbar vertebra to first sacral vertebra. The first scan (FM) was with fixed tube current of 320 mAs. The follow-up scan was with ATCM with noise index (NI) of 12.0 HU. At the levels of L3-4, L4-5 and 15-S1, image quality, image noise and radiation dose were measured and analyzed. Image quality and radiation dose were compared by paired t-test and the image noise was compared by ANOVA test. Results The dosage of the ATCM had a 31.3% reduction compared with FM, the average DLP was(187.9±66.4)mGy·cm and(273.4±45.4) mGy·cm respectively, where t = 8.205, P < 0.05. The average noise and their deviations for the FM group were (9.8±2.4) HU,(9.9±2.4) HU, and (11.5±3.2) HU at level of L3-4, L4-5, 15-S1, respectively. With ATCM, the average noise was(12.0±0.8) HU, (11.7±0.6) HU, and (11.7±1.4) HU, respectively. There was statistical difference between the two groups (F = 23.31, P < 0.05). The image quality scores for the FM group were (4.7±0.3), (4.5±0.2), (4.5±0.2) and showed no statistical difference to ATCM group (4.6±0.3), (4.5±0.2), (4.5±0.2) at level of L3-4, L4-5, L5-S1, respectively, where t = 1.000, P > 0.050 Conclusion ATCM technique with the noise index setting at 12.0 HU can achieved a 31.3% dose reduction while keep the consistent image quality for lumbar spine MSCT study.

Objective To investigate the effect of electro-acupuncture on the spinal nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signal pathway in a rat model of neuropathic pain (NP). Methods Forty-eight pathogen-free male SD rats weighing 190-210 g were randomly divided into 3 groups (n = 16 each):group Ⅰ sham operation (group S); group Ⅱ group NP and group Ⅲ electro-acupuncture + NP (group E). NP was induced by chronic constrictive injury (CCI). Right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 chromic catgut. In group E Huantiao and Weizhong points on the operated side were stimulated with electric stimulator (frequency 2 Hz, wave length 0.6 ms, starting at a voltage of 1mA and increasing by 1 mA every 10 min) for 30 min once a day at 11-17 d after CCI. Pain threshold to mechanical and thermal nociceptive stimuli was measured before (T0 , baseline) and at 10 and 16 d after CCI (T1, T2). The animals were sacrificed at 17 d after CCI and the lumbar segment (L4-6) was removed for determination of the activities of total NO synthase (tNOS), induced and neural NOS (iNOS, nNOS) (by spectrophotometry), NO content (by nitrate reductase method) and cGMP content (by immuno-histochemistry) in the spinal cord in 8 animals and the expression of iNOS and nNOS in the dorsal horn of the spinal cord (by immuno-histochemistry) in another 8 animals in each group. Results CCI significantly decreased the mechanical and thermal pain threshold at T1 and T2 as compared with the baseline at T0 in group NP and E. Hyperalgesia induced by CCI was significantly attenuated by electro-acupuncture at T2 in group E as compared with group NP.CCI significantly increased tNOS and nNOS activities, NO and cGMP content in the spinal cord and up-regulated nNOS expression in the spinal dorsal horn. Electro-acupuncture significantly attenuated the CCI-induced increases in tNOS and nNOS activities, NO and cGMP content in the spinal cord and nNOS expression in the spinal dorsal horn. There was no significant difference in the iNOS activity among the 3 groups. Conclusion NO-cGMP signal pathway in the spinal cord is involved in the acupuncture analgesia.

Objective To investigate the feasibility of using superparamagnetic iron oxide(SPIO)as MRI contrast agent to assess rat nonalcoholic steatohepatitis Kupffer cells(KC)function.Methods Twenty male SD rats were randomly divided into A and B groups,group A(n=10)was the experimental group fed high fat diet,group B(n=10)was the control group fed normal diet After 8 weeks,plain MR and SPIO enhanced MR were performed in all the rats.Blood lipids were measured,and HE and Perl's blue staining in all livers specimen was done.The related results of the staining were analyzed with t test Results Group A TC and TG levels[(6.58±1.25)and(1.53±0.23)mmol/L respectively]were significantly higher than group B[(1.64±0.22)and(0.55±0.14)mmol/L respectively](t=11.716 and 11.588,P＜0.01).Group A and B groups hepatic signal intensity decreased in all sequences after SPIO enhanced,but in group A the level of decline[(34.78±4.51)% and(60.38±3.49)% respectively]was less than group B[(64.96±2.42)% and(81.08±1.66)% respectively]on PDWI and T_1WI,and statistically significant differences(t=-18.451 and-16.240,P＜0.01)were found.In group A the ratio of signal intensity of liver to spleen(1.002±0.141,5.000±0.516,20.004±1.490 and 2.601±0.077 respectively)was more than group B(0.400±0.102,1.500±0.115,0.503±0.105 and-0.300±0.058)before and after contrast enhancement on PDWI,T_2WI,T_2~* WI andT_1WI(t=10.745,19.800,39.168 and 92.785,P＜0.01).Typical histological hepatic lesions of NASH were observed in group A,Perl's staining-positive particles in group A(2.33±0.50)were fewer than in group B(4)(t=-10.000,P＜0.01).Conclusion The high-fat diet induced model of SD rats was close to the human NASH and was easy to establish.Clinical application of SPIO enhanced MR successfully assessed the phagocytic activity of KC in the study,and it suggested that the pathogenesis of NASH was related to the decreased phagocytic activity of KC.
