ObjectiveTo explore the application of finasteride during ipratropium bromide treatment in the elderly with chronic obstructive pulmonary disease. Methods The 263 patients who were hospitalized for chronic obstructive pulmonary disease (COPD) and treated with ipratropium bromide (aged 63-89 years) in Cadre Wards of Ji Shui Tan Hospital from Jan.2006 to Jan.2011 were reviewed.They were divided by gender and combination of benign prostatic hyperplasia (BPH) and treatment of finasteride.The duration of ipratropium bromide treatment,time to dysuria and the severe degree of dysuria were evaluated.Results None of the female patients suffered from difficult urination or discontinued impratropium bromide for abnormal urination,while there were 23.3％ cases with difficult urination,5.8％ catheterization and 3.4％ discontinued bromide in male patients.More patients suffered from catheterization and bromide discontinuance in prostatic hyperplasia group (8.0 ％ and 4.7 ％ ) as compared with non-prostatic hyperplasia group (P＜ 0.05).The occurrence of urethral catheterization for dysuria or ipratropium bromide discontinuance obviously decreased 40％ and 30％,respectively,after finasteride treatment (P＜0.01). Conclusions The COPD patients complicated with BPH should be treated with finasteride to prevent the occurrence of abnormal urination and urinary retention during the treatment of ipratropium bromide.

Objective To discuss application of initiative infrared ray computer assisted 3D navigation system in spinal complex operation to improve surgical safety. Methods From December 2002 to July 2004, we performed 90 cases of spinal operation assisted by computer 3D navigation system. There were 38 cases of spinal fractures, and 236 cases of pedicle fixation. In lumbar spine surgery, fluoroscopy was commonly used, because the pedicle of lumbar spine was thick enough. 3D computer navigation was used in the other cases. Results 4 screws (1.7%) were not in good position, and the position error rate was 0.23 to 0.56 mm (automatically calculated by the computer). But we had once performed 272 cases of fixation with cervical pedicle screws just assisted by G arm or C arm fluoroscopy, 29 (10.7%) of which were not in good position. Conclusion In comparison, computer navigation assisted operation can make pedicle screw positioning more correct.

Technological advances in spinal surgery have brought about changes to the theories and methods of treatment of spinal fractures. New techniques, such as pedicle screw fixation, upper cervical fixation, minimal invasive method, computed navigation method, have made it possible that much more spinal fractures can be treated operatively rather than conservatively. These changes have also made the recovery of patients more satisfactory. But if the new techniques are not used properly, they can do harms to the patients. Therefore, how to apply the new techniques properly and avoid unnecessary harms to the patients at the same time is a serious problem that we must face and solve.

Objective To report a case of neuromyelitis optia with hiccups as the first symptom. Methods 1 case received laboratory examination according to the clinical symptoms, signs, especially aquaporin-4. Results Aquaporin-4 antibody was positive. Conclusion Aquaporin-4 may play an important role in the pathogenesis of neuromyelitis optia.

Objective To investigate the effect of visfatin on the NG2 cell number in the brain of normal rats and rats with cerebral ischemia/reperfusion (I/R) injury. Methods Transient focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO) and a monofilament suture via intraluminal approach in rats. Thirty adult male Wistar-Kyoto rats were randomly divided in to four groups, namely, a sham operation group (Sham), a cerebral I/R model group(MCAO), Sham+FK866(a specific inhibitor of visfatin) group, and cerebral I/R+FK866 group. Animats nn the latter two groups were intragastsically given FK866 (1 mg/[kg • d]) for a consecutive of 14 days; Sham operation or MCAO was pefformed at the 7th day of FK866 treatment. The NG2 cells were observed by immunofluorescence staining in animal brains at the 7th day after surgery. Results There was no signficant difference in NG2 cell numbeis between the Sham group and Sham + FK866 group. Cerebral I/R model group had significantly less NG2 cells in the core region of infarction(P<0. 01) and significantly more in the penumbra area (P<0. 01) compared with the Sham group, with no significant change in the contralateral side. The NG2 cell numbers were not significantly different between the cerebral I/ R model group and cerebral I/R + FK866 group in the above mentioned areas. Conclusion Inhibition of visfatin shows no noticeable effect on NG2 cell number in the brains of normal and cerebral I/R rats, indicating that the neuroprotective effect of visfatin is not assoiiated with NG2 cells.

Objective To culture the osteoblast of Wistar rat in vitro and study its biological characteristics. Methods With heat-cool alternative method and by way of the trysin digestion, the osteoblast cells, obtained from femoral bone of Wistar rats, were colleced and cultured with special cultural fluid in vitro. After about two weeks, cells lined up in one layer. Then cells were generationed and examined by phase contrast microscope, H E strain, ALP strain, type Ⅰ and type Ⅲ collagen strains. Results The cells had the same morphological feature with ALP activity, type Ⅰ collagen strain positive. Conclusion The cultured osteoblasts derived from bone mass were seed cells for the bony tissue engineering, which is the base for the tissue-engineering born construction in vitro.

Objective To develop a method to analyze functional grouping cDNA microarray gene expression in microvessels and neurons from rat brain using laser capture microdissection(LCM). Methods Microvessels and neurons were captured using the PixCell ⅡLCM instrument. The total RNA was extracted from the LCM samples according to the manufacturer's protocol of RNAqueous-Micro kit. The total RNA were processed for one round of T7-based RNA amplification; cDNA probe were synthesized using gene-specific primer and labeled for cDNA microarray analysis. Results Amplified RNA from microvessels and neurons allowed us to measure 96 gene expression in functional grouping cDNA microarray. Conclusion LCM allowed us to harvest pure microvessels and neurons from their native tissue environment, combined with methods of T7 RNA amplification and gene-specific primer amplification so that we can analyze functional grouping cDNA profiling in LCM samples.

Objective:To investigate the protective effects of Ruanmai Capsules on cerebral ischemia-reperfuse injury in rats.Methods:A cerebral ischemia-reperfuse model in rats was established by ligaturing bilateral arterial carotis communis and vagus nerve. NO, 6-keto-PGF 1a and TXB 2 in serum were examined. Results: Ruanmai Capsule (0.81g/kg and 2.43g/kg,po) increased the levels of NO, 6-keto-PGF 1a. It also had the tendency to decrease TXB 2 in serum. Conclusions: Ruanmai capsules can alleviate brain injury caused by cerebral ischemia reperfusion. The effect is achieved perhaps by inhibiting platelet aggregation and increasing NO.
