Objective: To evaluate the diagnostic value of transbronchial lung biopsy (TBLB) via bronchoscope for lung diffuse lesions and peripheral pulmonary lesions. Methods: The results of TBLB were retrospectively analyzed from 256 diagnoses of unknown patients with lung diffuse lesions or peripheral lung lesions. Results: Eighty-nine final diagnosis cases via TBLB only once, the diagnostic rate of double lung diffuse lesions was the highest, [51.06%(24/ 47)], local non-nodule lesions, nodule lesions, cavity lesions were 33.33%(23/69), 29.91%(35/117), and 28.57% (4/14), respectively. Among 24 diagnostic cases of double lung diffuse lesions, there were 6 cases of pneumonia of pulmonary tuberculosis, 9 cases of lung carcinoma, 7 cases of adenocarcinoma; 6 cases of pneumonia, 2 cases of fungous infection, and 1 case of lung hemosiderosis. The diagnostic yield about 58 cases of local lesions was low, among which non-nodule lesions accounted for 33.33% and nodule lesions accounted for 29.91%. In 89 cases of peripheral lung lesions with histological diagnosis, lung carcinoma and pulmonary tuberculosis were frequent diseases, which accounted for 86.52%. Conclusion: TBLB is a reliable, safe, effective and repeatable operation method in diagnosis of lung diffuse lesions and peripheral pulmonary lesions.

Objective To clarify the possible role of cyclooxygenase-2(COX-2), intercellular adhesion molecule-1(ICAM-1) and E-selectin in the inflammatory injury induced by cerebral ischemia and reperfusion. Methods The focal cerebral ischemia and reperfusion model was induced by a suture occlusion of the right middle cerebral artery. The rats were randomly assigned to four groups: sham operated group; 4 h,22 h and 46 h reperfusion groups. The expression of ICAM-1, E-selectin and COX-2 were detected by immuno-Western blot and immunohistochemical method. Myeloperoxidase (MPO) activity was detected by a commercial MPO kit. Results In the right cortex and striatum of the sham operated group and the 4 h, 22 h and 46 h reperfusion groups, the relative values of COX-2 were 0.7642?0.0763, 1.5382?0.1047, 1.6491?0.3265, 1.8020?0.3719 and 0.7104?0.0891, 2.2061?0.2143, 1.7897?0.3537, 1.8018?0.5703 respectively; the relative values of ICAM-1 were 0.6845?0.0531, 0.9115?0.0422, 0.9426?0.0407, 1.0756?0.0467 and 0.6583?0.0361, 0.9439?0.0746, 0.9975?0.1532, 0.8808?0.0497 respectively. Significant increase of MPO activity and expression levels of COX-2, ICAM-1 and E-selectin were shown from 4 h to 46 h in the striatum and cortex of rats following reperfusion. Immunohistochemical staining showed that the number of ICAM-1 and E-selectin positive vessels was increased in the border of ischemia. The positive cells of COX-2 were almost neurons in the cortex, but in the striatum, the cells were neurons, glias and vessel endothelium. Positive correlation between COX-2 and ICAM-1 expression in the cortex(n=6,r=0.973,P

Objective To explore the joint toxic effect of formaldehyde and benzene on testicles of the mice. Methods 78 Kunming male mice were divided into groups, in the formaldehyde treatment groups were exposed at dosage of 0.2 mg/kg,2 mg/kg,20 mg/kg, in the benzene treatment groups were exposed at dosage of 100.0 mg/kg,200.0 mg/kg,400.0 mg/kg and the in formaldehyde and benzene combined treatment groups were exposed at dosage of 0.1+50.0 mg/kg,1+100.0 mg/kg,10+200.0 mg/kg respectively. The treatments were conducted by peritoneal injection for five consecutive days,once a day,then killed on 6th day. The activity of superoxide dismutase(SOD),the contents of maleic dialdehyde(MDA),the contents of copper(Cu),zinc(Zn) in testicles of the mice were determined. Results Compared with those in the negative control groups,the activity of SOD and the contents of Cu, Zn in the testicles of the mice in each treatment group significantly decreased, while the contents of MDA significantly increased (P

OBJECTIVE:To investigate the pharmacoeconomic efficacy of four chemotherapeutic schemes for advanced non-small cell lung cancer in elderly patients.METHODS:92 elderly patients with advanced non-small cell lung cancer were randomly divided into four groups:GP,NP,PC,and TP groups.The pharmacoeconomic efficacy of the four groups was analyzed and evaluated retrospectively using the cost-minimization analysis in pharmacoeconomics.RESULTS:The costs of GP,NP,PC,and TP schemes were 10 820.69 yuan,5 864.54 yuan,7 595.57 yuan,and 7 774.64 yuan,respectively(P0.05),respectively.The adverse drug reactions were characterized by different degree of myelosuppression and gastrointestinal reactions,all were cured on symptomatic treatment.CONCLUSION:The cost-minimization analysis showed that NP scheme is the optimal one of the four schemes.

Objective To explore the methods of large sample research for traditional Chinese medicine(TCM) symptoms of exercise-induced diseases and to define the main symptoms and the main symptom compositon of exercise-induced diseases.Methods The methods of TCM theory of differentiation of syndrome, epidemiology study and multivariable statistical analysis were properly combined. We investigated 518 cases of exercise-induced insomnia(EII) by using the clinical epidemiology program with the uniform diagnostic standard and data processing method.Results The asthenia of both the heart and the spleen(56 cases, 10 8%) was one of the primary syndrome of EII.Conclusions This study showed that main symptoms in differential diagnosis of asthenia of both the heart and the spleen might be sleeplessness, poor appetite, excessive dream, dizziness and weakness of limb.

Objective To investigate the expression and significance of survivin and CD44v6 in non-small cell lung cancer (NSCLC) and their correlation. Methods SP immunohistochemical technique was used to detect the expression of survivin and CD44V6 protein in 53 cases of NSCLC and 13 cases of para-eaneer nor-mal tissues. Results The positive rate of survivin and CD44v6 in NSCLC was 60. 38% and 69. 81% respec-tively,which was higher than that of normal pulmonary tissues adjacent to carcinoma(P <0. 01). The expres-sion of survivin and CD44v6 in NSCLC was related to lymph node metastasis (P < 0. 05), but not to patients' age and gender(P>0.05). The expression of survivin was related to TNM stages and cell differentiation (P <0. 05) ,but not to histology type(P >0. 05). The expression of CD44v6 in squamous carcinoma was significantly higher than that of adenocareinoma (P <0. 05),but the expression of CD44v6 was not related to TNM stages and cell differentiation (P >0. 05). There was no correlation between the expression of survivin and C1)44v6 (r = -0. 058, P >0. 05). Conclusion Survivin might be used to evaluate NSCLC development;CD44v6 might be used for the differential diagnosis of squamous carcinoma in NSCLC;both of them might be helpful to predict the metastasis of NSCLC. They might be two independent events in the process of NSCLC genesis and develop-ment.

Objective:To review the clinical efficacy of botulinum toxin type A(BTX-A)in the treatment of trigeminal neuralgia (TN).Methods:The main bibliographic databases were searched from English and Chinese literatures on the topic and the refer-ences of the identified articles were also searched for additional studies.2 reviewers assessed the quality of the included studies and extracted data duplicate.Results:3 Chinese and 1 English reports with 203 participants were included.However,substantial hetero-geneity(I2 =77%)precluded meta-analysis and the results were individually described.3 trials reported that BTX-A was more effec-tive than the control and 1 showed no difference between groups.Adverse effects of BTX-A were reported in 4 reports and were mild to moderate.Conclusion:BTX-A is effective in treating TN with few adverse effects.However,the evidence is weak because of a few studies included and most of them with low methodological quality.Further studies with high quality are needed to testify the evidence.

Objective To explore the association between rs7049105, rs647188, rs1333035 of chromosome 9p21 and the LAS among Chinese Han population of Changsha;to explore the association between rs7049105, rs647188, rs1333035 and the LAS among patients with evidence of cephalic and cervical vessel atherosclerosis. Methods The present study com?prised 229 LAS patients and 233 healthy controls. The 233 controls which we defined control group 1. In the controls, 150 (64.38%)controls with evidence of atherosclerosis were defined as control group 2, 83(35.62%)controls without evidence of atherosclerosis were defined as control group 3. The sample genotyping was detected using MALDI-TOF-MS. Results There was no polymorphism of rs647188 among case group and control group 1. There was no significant difference in the polymorphism distribution of rs7049105 and rs1333035 between the case group and control group 1 and 3 (P>0.05). There may be no significant different in the polymorphism distribution of rs7049105 between the case group and control group 2 . The rs1333035 was associated with risk of LAS among patients with evidence of cephalic and cervical vessel atherosclerosis (χ2=6.502,P=0.039). Conclusions The rs10757274 and rs7049105 polymorphism in the chromosome 9p21 may not be as?sociated with risk of LAS among Han population of Changsha. There may be no polymorphism of rs647188 among Han popu?lation of Changsha. The rs1333035 polymorphism may be associated with plaque rupture and thrombosis.
