Objective To investigate the severity of cough in patients with different etiology of chronic cough and its related factors. Methods One hundred and fifty patients with chronic cough were recruited. The diagnosis of the patients was as follows: 24 cases with post nasal drip syndrome (PNDs), 26 cough variant asthma (CVA), 20 gastroesophageal reflux-induced cough (GERC), 31 eosinophilic bronchitis (EB), 30 atopic cough (AC) and 19 cough post infection (CPI). The severity of cough at daytime and night-time were scored by the doctor and the patient at the first visit. The correlation between cough score and age, gender and course duration of patients was analyzed. Results There was no significantly difference of cough score at daytime among different groups. Cough score at night in CVA group was significantly higher than that of other five groups (all P <0.01). Regression analysis showed that cough score at daytime was significantly correlated with age of patients (P < 0.05), while cough score at night was correlated significantly with gender (P < 0.01). Conclusion Cough severity at daytime in different etiology of chronic cough is similar, while that at night in patient with CVA is higher than that with other etiology.

Objective To investigate the effect of focal cerebral ischemic preconditioning (IPC) on brain edema and the expression of nuclear factor-?B( NF-?B) and its target gene MMP-9. Methods Forty-five SD rats were divided into 3 groups in which control group received sham surgery only, and the other two groups received 2 hours of middle cerebral artery occlusion (MCAO) followed by 22 hours of reperfusion with or without 10 minutes of IPC 3 days before. Brain water content, expression of NF-?B and MMP-9 mRNA were evaluated in each group by wet-dry weight method, immunohistochemistry staining and RT-PCR. Results Compared with the SS group, there was a lower NF-?B immunoreactivity and MMP-9 mRNA level (16 098.2?1 265.3 vs 23 565.8?1 978.4,50.7% vs 84.1%, P

Objective To determine the serum levels of cross-linked telopoptide of type Ⅰ collagen (ICTP),alkaline phosphatase (ALP) in patients with primary malignant bone tumor,primary benign bone tumor and malignant tumor metastasized to the bone,and to explore the clinical value of ICTP and ALP in identification and diagnosis of bone tumor.Methods Sixteen primary malignant bone tumor patients,16 primary benign bone tumor patients and 18 malignant tumor metastasized to the bone patients in 2012 were studied.Serum ALP was assayed by SFBC rate method and ICTP by enzyme linked immunosorbent assay (EIA).Results The serum levels of ICTP was not significantly different between primary benign bone tumors and normal control group (P ＞ 0.05),but the other between-groups had statistically significant difference (P ＜ 0.05).The serum levels of ALP in malignant tumor metastasized to the bone was significantly higher than the rest of the group (P ＜0.01),but the difference between the remaining groups was not statistically significant (P ＞ 0.05).The area under roc curve (AUC) of ICTP for diagnosis of primary benign bone tumors,malignant tumor metastasized to the bone,primary malignant bone tumor (0.923,0.926,0.874) was higher than the ALP (0.354,0.702,0.865).Conclusions Serum ICTP and ALP were sensitive and convenient biochemical indices which reflected metabolism of patients with bone tumor.Serum ICTP was more specific and sensitive than ALP and they have clinical importance for differential diagnosis as an index of bone tumor.

Objective To explore the protective effect of rosiglitazone on insulin resistance( IR)induced by high glucose in vascular endothelial cells and its possible mechanism. Methods Human umbilical vein endothelial cells( HUVECs) was divided into 3 groups:the normal control group cultivated in DEME medium with 5. 5 mmol·L-1 glucose;the high glucose group( HG)cultivated in DEME medium with 33 mmol · L-1 glucose for 24 h after the IR model was set up;the rosiglitazone group cultivated in DEME medium with 33 mmol·L-1 glucose and 10 μmol·L-1 of rosiglitazone for 24 h after the IR model was set up. The cell viability,nitric oxide(NO),endothelin-1(ET-1),mitochondrial membrane potential,reactive oxygen species ( ROS),p-IKK and IkBa protein levels were detected. Results Compared with the normal control,the cell viability,the level of NO and the mitochondrial membrane potential were decreased,levels of ET-1 and ROS increased,p-IKK expression was up-regulated,and IκBα expression was down-regulated in HG group(all P〈0. 01). Rosiglitazone reversed these changes in a time-dependent manner(P〈0. 05). Conclusion Rosiglitazone has the protective effect on insulin resistance induced by high glucose in vascular endothelial cells via inhibiting ROS/IKK signaling pathway.
