Methods The clinical manifestations and related laboratory results of 13 inpatients treated in West China Hospital of Sichuan University from January 2005 to June 2010 were reviewed retrospectively. Results The incidence of infection in these patients was 100% with tuberculosis as the most common infection. Apart from the abnormality of T lymphocytes, most patients had a change of hematology and biochemistry, including anemia, depression of leucocytes and platelets, hyperglobulinemia and hypoproteinemia; HIV-infected patients may also presented with rheumatic manifestations or abnormality in the immune system. Conclusion The clinical manifestations of patients with AIDS are complicated. Many kinds of infections and rheumatic manifestations may merge and the change in hematology and immunology is common.
Objective To investigate the effects of methylprednisolone on airway inflammation of chronic bronchitis in rats, and to explore its possible mechanism. Methods Forty SD rats were randomly divided into five groups, ie. a blank control group, amethylprednisolone control group, a model group, and two methylprednisolone intervention groups. Chronic bronchitis model was established by cigarette inhalation in the model group and two intervention groups. Methylprednisolone was injected intraperitoneally in the two intervention groups before exposing to cigarette smog ( at the dose of 1 mg/ kg and 10 mg/ kg, qd,respectively) . The protein expression of phosphodiesterase 4D ( PDE4D ) in trachea and lung samples was determined by immunohistochemical staining. The average optical density of positive staining of PDE4D was determined by image analysis technique and gray scale scanning. Bronchoalveolar lavage fluid ( BALF) was collected for total and differential cell counts, and the concentrations of TNF-αand interleukin-8 ( IL-8) in BALF were detected by ELISA. Results Cigarette smoking induced obvious airway inflammation in themodel group, and the inflammation was alleviated in the two methylprednisolone intervention groups.Compared with the two control groups, the expression of PDE4D was obviously elevated in tracheal and lungs in the model group( P lt; 0. 05) . Moreover, the increased expression of PDE4D was positively related with theincreased release of TNF-αand IL-8 in BALF. The expression of PDE4D and the release of TNF-αand IL-8 in BALF were decreased after the treatment with methylprednisolone in a dose-dependent manner ( P lt;0. 05) . Compare with the low dose intervention group, there was no markedly difference related to PMNnumber and TNF-α release in the high dose intervention group ( P gt; 0.05) . Conclusions Methylprednisolone may alleviate airway inflammation of chronic bronchitis by inhibiting the expression of PDE4D in rats. Inhibition of PDE4D may down-regulate TNF-αactivity, which may further reduce IL-8 release and alleviate airway inflammation.
It is the functional connectivity between motor cortex and muscle that directly relates to the rehabilitation of the dysfunction in upper limbs and neuromuscular activity status, which can be detected by electroencephalogram-electromyography (EEG-EMG) coherence analysis. In this study, based on coherence analysis method, we process the acquisition signals which consist of 9 channel EEG signal from motor cortex and 4 channel EMG signal from forearm, by using 4 groups of hand motions in the healthy subjects, including flexor digitorum, extensor digitorum, wrist flexion, and wrist extension. The results showed that in the β-band, the coherence coefficients between C3 and flexor digitorum (FD) was greater than extensor digitorum (ED) in the right hand flexor digitorum movement; the coherence coefficients between C3 and ED was greater than FD in the right hand extensor digitorum movement; the coherence coefficients between C3 and flexor carpi ulnaris (FCU) was greater than extensor carpi radialis (ECR) in the right hand wrist flexion movement; the coherence coefficients between C3 and ECR was greater than FCU in the right hand wrist extension movement. This analysis provides experimental basis to explore the information decoding of hand motion based on corticomuscular coherence (CMC).

ObjectiveTo observe the treatment effects of zoledronic acid on postmenopausal osteoporosis. MethodsSeventy-two postmenopausal osteoporosis patients from July 2007 to December 2010 were randomly divided into observation group and control group, with 36 patients in each. Traditional drug treatment was used in the control group, while traditional drug treatment and zoledronic acid were used for patients in the observation group. The Indicator of bone mineral density (BMD) and ostocalcin were used to comapre the treatment effects between the two groups after one-year treatment. ResultsThere was a significant difference in BMD and osteocalcin in both the observation group and the control group before and after treatment (P<0.05). The treatment effect is superior in the observation group (P<0.05). ConclusionZoledronic acid is an effective treatment for postmenopausal osteoporosis; it can increase BMD and osteocalcin more effectively.
目的 分析轮状病毒性腹泻患儿心肌受损情况和所伴随生化检验指标改变。 方法 2008年7月－2010年7月收治腹泻患儿80例，年龄6～27个月，平均12.9个月。其中有50例为轮状病毒腹泻（A组），30例为非轮状病毒性腹泻（B组）。A组患儿均符合轮状病毒腹泻诊断标准，有心肌损伤的异常指标但达不到心肌炎诊断标准者诊断为心肌损害。B组患儿有水样腹泻，但症状较轻，病程较短，轮状病毒抗原检测阴性。用全自动生化分析仪测定血清谷草转氨酶、乳酸脱氢酶、肌酸磷酸激酶和肌酸磷酸激酶同工酶，免疫亲和层析法测定血清肌钙蛋白值，并进行心电图检查。 结果 A组50例轮状病毒性腹泻患儿中，44例（88.0%）存在心肌损害，其血清谷草转氨酶（74.32 ± 13.77）U/L、肌酸磷酸激酶（52.01 ± 10.37）U/L、肌酸磷酸激酶同工酶（273.43 ± 27.55）U/L均升高，且明显高于B组[（24.98 ± 7.03）、（17.11 ± 6.52）、（151.46 ± 16.52）U/L]，差异有统计学意义(P＜0.05)。两组患儿的乳酸脱氢酶变化差异无统计学意义(P＞0.05)。 结论 轮状病毒性腹泻患儿往往伴有心肌损害及相应的血液生化检测指标改变；以肌酸磷酸激酶同工酶作为近期心肌损害的诊断指标更为特异和敏感。
