Objective To evaluate the therapeutic effect of antituberculosis therapy in elderly patients with smear-negative pulmonary tuberculosis by low-dose computed tomography (CT).Methods Forty-seven elderly patients diagnosed as smear-negative pulmonary tuberculosis were rechecked with low-dose chest CT scan (120 kV, 20 mAs) after 1-12 months of antituberculous therapy respectively. These images were compared with common CT before treatment (120 kV, 200-280 mAs). Results In the elderly patients with smear-negative pulmonary tuberculosis, the most common CT signs before treatment were acinus consolidation (100%) and lobar or segmental consolidation (77%), but the cavity was seen less. After effective antituberculous therapy, tree-inbud was improved after one to three months, the acinus consolidation and lobular or segmental consolidations were improved after four to nine months, and the cavitations were slowly improved after six months. Conclusions Low-dose CT can provide sufficient information for the therapeutic effects of antituberculous therapy of smear-negative pulmonary tuberculosis in the elderly and could be used for rechecking.

Objective To investigate the number of osteoclast (OC) precursor in the peripheral blood of patients with ankylosing spondylitis (AS) and its relationship with serum receptor activator of nuclear factor KB-ligand (RANKL) and Osteoprotegerin (OPG) concentration as well as the disease activity. Methods The peripheral blood mononuclear cells from 8 cases of AS patients and 5 healthy controls were cultured in the medium containing macrophage colony-stimulating factor (M-CSF) (25 ng/ml) and RANKL (40 ng/ml). After being cultured for 14 days, cytochemistry was applied to detect tartrate-resistant acid phosphatase (TRAP) expression and the cells with TRAP expression and ≥3 nuclei were counted and defined as OC. Bone resorption assay was used to demonstrate OC function. ELISA was used to measure serum RANKL and OPG concentration in 23 cases of AS and 17 healthy controls. The relationship was analyzed in AS patients between the number of OC precursors and serum RANKL and OPG concentration as well as the disease activity. The indicators of disease activity were Bath ankylosing spondylitis disease activity index (BASDAI), Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). T test, t' test and Spearman correlation were selec-ted. Results ① Significantly higher OC production was observed in the peripheral blood of AS patients than that of healthy control group. The OC number per ten fields was 10.9±3.4 and 6.2±1.3 respectively (P<0.05); ② There was significant difference between AS patients and healthy controls in serum concentration of OPG and RANKL and the ratio of RANKL/OPG. OPG was significantly higher in AS patients [(157±49) pg/ml] than in healthy controls [(105±20) pg/ml] (P<0.05). RANKL was significantly higher in AS patients [(5.4± 3.8) pg/ml] than in healthy controls [(1.6±0.8) pg/ml] (P<0.05). The ratio of RANKL/OPG was significantly higher in AS patients (0.037±0.026) than in healthy controls (0.016±0.008) (P<0.01 );③Significantly positive correlation was observed between the OC number and the serum concentration of RANKL (r=0.692, P=0.009), the ratio of RANKL/OPG (r=0.813, P=0.001);④ In AS patients, serum concentration of OPG was found to have significantly negative correlation with BASDAI (r=-0.444, P=0.044). Serum RANKL concentration was found to have significantly positive correlation with BASDAI (r=0.543, P=0.011). The ratio of RANKL/OPG was found to have significantly positive correlation with BASDAI (r=0.672, P=0.001). Conclusion ① More OC precursors exist in the peripheral blood of AS patients. These cells may differentiate into osteoclasts, which might play a role in joints destructions in AS;② The mechanism of high OC production is likely to be due to high RANKL concentration which is caused by inflammatory reaction.

[Objective] To explore the genetic mechanism of acupoint catgut embedment in inhibiting hippocampal neuron apoptosis in rats with status epileticus (SE). [Methods] Forty SD rats were randomized into 5 groups: blank control (A), model (B), dilantin (C), routine acupuncture (D) and acupoint catgut embedment (E). Rat models of SE were established by intra-abdominal injection of penicillin. With immunohistochemical method, the expressions of apoptosisrelated genes of c-jun and bcl-2 were observed in the vulnerable neurons of the hippocampus 24 hours after modeling. [Results] Compared with SE model group, the expression of c-jun was decreased and the expression of bcl-2 was increased in group C, D and E 24 hours after modeling; c-jun expression was positively related with the apoptotic index (AI) and bcl-2 expression was negatively related; the effects in group E much differed from those in model group. [Conclusion] The possible mechanism of the acupoint catgut embedment in treating epilepsy is related to the inhibition of the hippocampal neuron apoptosis by prohibiting the expression of c-jun and promoting the expression of bcl-2.
