Bronchiectasis is a kind of chronic lung disease which threatens the health of children in China.It can affect the lung function,life quality and development of the patients.There are varied causes of bronchiectasis,and some of the causes have the special intervention.So the etiology diagnosis of bronchiectasis is important.The aims of the treatment of bronchiectasis is removing the causes,releasing the symptoms,preventing the acute exacerbation,sustaining the lung function and life quality.It needs a long tern combine therapy.

Objective To investigate the significance of the changes in heart rate variability (HRV) in patients undergoing coronary artery bypass graft procedure Methods Thirty six patients scheduled for elective coronary artery bypass were studied HRV was monitored by HXD I monitoring system one day prior to surgery (as baseline values), before anesthesia, at the end of surgery and on the 3rd day and 6th day after surgery Results The baseline logical values for total power(TP), low frequency (LF), high frequency (HF), LF/HF ratio were 3 07?0 35, 2 38?0 47, 2 37?0 54 and 1 34?0 93 respectively There were no significant changes in all these parameters before anesthesia as compared to baseline values LF,HF and TP decreased significantly on the 3rd day after surgery as compared with baseline values, and were kept at the level on the 6th postoperative day Conclusions The decrease in HRV power can last over 6 days after coronary bypass graft surgery, signifying reduced autonomous regulation of heart in the early postoperative days

Objective To assess the value of susceptibility weighted imaging(SWI) in the diagnosis of intracranial hemorrhage. Methods Forty patients with intracranial hemorrhage underwent MRI scanning (GE Signa HDe 1.5 T), which included T2WI, T1WI, T2 * WI and SWI. Of them, DWI was conducted in 37 cases and enhanced MRI was conducted in 10 cases additionally. After post processing on the workstation, both magnitude and phase images of SWI were acquired for further analysis. The images of all sequences were scored from 1 to 3, according to their ability of depicting the lesions. Statistical analysis was conducted to compare the scores among these sequences. Results On SWI, the scores in detecting the lesions, their margin and adjacent veins were 2. 8, 2. 8, and 2. 8 respectively. The scores of those were 1.8, 1.7,and 0.0 on T1WI, 2.3, 2.0 and 0.0 on T2WI, 2.0, 2.1 and 0.2 on T2* WI, respectively. There was statistical difference between the scores on SWI and those on T1WI, T2 WI and T2 * WI ( P < 0. 01 ). The numbers of micro hemorrhagic lesions that could be observed on SWI, T1WI, T2WI, DWI and T2 *WI were 402, 55, 61, 84 and 188 respectively. There was statistical difference in showing micro hemorrhagic lesions between SWI and T1WI, T2WI, DWI, T2 * WI (P < 0. 01 ). Conclusion SWI is sensitive to visualize the hemorrhagic region, and has predominant advantage over conventional MR sequences including T2 * WI in detecting intracranial hemorrhage, especially cerebral microbleeding. According to the features of the paramagnetic and diamagnetic lesions, radiologists can differentiate hemorrhage and calcification with phase images.

Objective: To observe the effects of Jinqi Jiangtang Tablet, a compound Chinese herbal medicine, on serum matrix metalloproteinase-9 (MMP-9) level and MMP-9 expression in peripheral blood monocytes of rats with streptozocin-induced diabetes. Methods: Thirty Wistar rats were randomly divided into 3 groups: control group, untreated group and Jinqi Jiangtang Tablet group. Diabetes in rats was induced by a single intraperitoneal injection of streptozocin (70mg/kg body weight). After model building, rats in the Jinqi Jiangtang Tablet group were administered with Jinqi Jiangtang tablets at a dose of 0.8 g/(kg·d) for 6 weeks and rats in the control group and the untreated group were treated with normal saline. After treatment, level of fasting serum glucose was detected by hexokinas method; serum MMP-9 level was tested by enzyme-linked immunosorbent assay; MMP-9 expression in peripheral blood monocytes was measured by reverse transcription-polymerase chain reaction and Western blot method. Results: After treatment, fasting serum glucose level in the Jinqi Jiangtang Tablet group was less than that in the untreated group (P<0.05). After modeling, the serum MMP-9 level of rats in the untreated group was (9.11±3.55) μg/L and that in Jinqi Jiangtang Tablet group was (8.97±3.07) μg/L, which were higher than that in the control group ((4.39±1.44) μg/L) (P<0.01). After gavage, the level of serum MMP-9 was lower in Jinqi Jiangtang Tablet group than in the untreated group (P<0.05). The expression of MMP-9 in peripheral blood monocytes in the untreated group was higher than that in the control group (P<0.05). The MMP-9 expression in peripheral blood monocytes of rats with diabetes was down-regulated by Jinqi Jiangtang Tablet (P<0.05). Conclusion: Jinqi Jiangtang Tablet can decrease the level of serum MMP-9 and down-regulate the MMP-9 expression in peripheral blood monocytes at both mRNA and protein levels in rats with diabetes.

Objective To investigate the effect of small interference RNA(siRNA) targeting RRM2 on the biological behavior of human osteosarcoma cell line Saos-2 and the molecular mechanisms.Methods RRM2 expression was knocked down in human osteosarcama cell line Saos-2 by RRM2 siRNA.The expression of RRM2 mRNA and protein was determined in human osteosarcoma cell line Saos-2 and human osteoblast-like cell line hFOB1.19 by real time-PCR and Western blot.The cell proliferation was detected by CCK-8.The migration was observed by using transwell system.The apoptotic rate was observed by ELISA.The expression of CyclinD1 and Bcl-2 proteins were detected by Western blot.Results The expression of RRM2 mRNA and protein was higher in Saos-2 than in hFOB1.19.siRRM2 could down-regulate the expression of RRM2 in Saos-2 cells in a time-and concentration-dependent manner.CCK-8 assay showed that si-RRM2 could inhibit the proliferation ability of Saos-2 cells in a time-and concentrationdependent manner,but had no effect on the proliferation of hFOB1.19 cells.Transwell assay indicated that si-RRM2 could inhibit the migration of Saos-2 cells.si-RRM2 combined with adriamycin could increase the apoptosis of Saos-2 cells.Western blot showed that the expression of Cyclin D1 and Bcl-2 were decreased by silencing RRM2.Condusion RRM2 overexpression maybe associate with the osteosarcoma cells proliferation and migration and suppression of its function is a potential therapeutic strategy in osteosarcoma.

Objective: Our purpose was to explore the protective role of Salvia Miltiorrhiza (SM) on gentamicin (GM) ototoxicity. Methods: We used NADPH-diaphorase in histochemical staining and image quantitative analysis technique, combined with auditory brainstem response (ABR) measurement to investigate the change of nitric oxide synthase (NOS) activity in cochlea of guinea pig after the injection of GM and SM. Results: Gebtamicin and SM significantly reduced NOS activity in cochlear and the threshold of ABR compared with GM alone (P<0.01); and the threshold of ABR was in high correlation with NOS activity (rGM= －0.8236 ～ －0.8662; rSM+GM= －0.8628 ～ －0.9172, P<0.01). Conclusion: Salvia Miltiorrhiza can reduce NOS activity in cochlea, alleviate GM ototoxicity, and ameliorate hearing function.
