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 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.

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 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.

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 The sponge of the small intestinal submucosa(SSIS) is established by the material chemistry,in order to supply the database for the scaffold of the dermic tissue engineering.Methods At the regular temperature,the SSIS was conducted firstly by the physiochemical method.Then,the SSIS was crosslinked by the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) so as to get the three dimentional SSIS.The morphological feature was obtained by the lighting and electron microscope,ophthalmic oberservation,the embedding in the mouse of the SSIS was used to observe the adsorbing and immunology.The results were analyzed by statistic software.Results The crosslinked SSIS was regular in the structure and not loosen,the framework was equilibrium,the pore was abundant with the diameter of the 100 ～ 200μm,the difference was obvious (all P ＜ 0.05).The firstweek after embedding did not exist the adherence leukocyte infiltration,the vascularization occur in the third week.The material was completed and had no elastic degradation.Conclusion Reconstructed SSIS has completed structure,elastic with the vascularization and minor immunology,which could be used as the extracellular scaffold for the dermic tissue engineering.

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.

Axial symptom,also called axial pain or axial neck pain,is a common complication after posterior cervical spine surgery.The symptom can be neck pain,as well as rigid,tension and dullness.The incidence of axial syndrome is estimated between 5.2％ and 61.5％.Often,the symptom does not disappear spontaneously.The quality of patients' life as well as the effectiveness of cervical laminoplasty is affected.It can be divided into early and late axial pain based on the onset time.The mechanism and reason are different,but both are difficult to subside.The incident of axial symptom is relatively high in conventional laminoplasty.However the modified one which preserve posterior ligament-muscular structure can reduce the incidence significantly.C2 spinal process as the attachment of cervical semispinalis,could reduce the incidence of kyphosis after operation.And C7 spinal process is an important structure in posterior ligament-muscular structure.Both should be preserved as much as possible in order to maintain intact attachment of muscles,which facilitates the patient to restore soft tissue tension by rehabilitation.Rigid fixation is another method of modification,it could avoid re-close of the open door,and reduce soft tissue injury.However,attention must be paid not to destroy facet joint to cause new axial symptom.Risk factors of axial symptom include past shoulder and neck pain and stiffness,others remain controversial.There is no correlation between loss of range of motion after surgery as well as change of cervical alignment and axial symptom.It is more likely to be a different result due to muscle atrophy.Although there are no golden standard of laminoplasty,doctors should follow these principles:preserve C2 and C7 spinal process when possible,rigid fixation to avoid reclose,reduce immobilization after operation,and encourage patient to start rehabilitation as early as possible to reduce incident of axial symptom.

Objective To assess the diagnostic value of 3D-CE MRA for nutcracker syndrome (NCS).Methods The 3D-CE MRA appearances of 4 patients of NCS and control group ( 30 persons) were analyzed.Results The left kidney vein (LKV) crossed before abdominal aorta in 4 NCS patients and 30 controls- The average angle of the origin of the superior mesenteric artery (SMA) from the abdominal aorta was (84.50±3.60)° in control group,and became small (<30°) in 4 NCS patients.The distance of the origin of the SMA to the beginning of descent was (13.40±5.10) mm,and the SMA and abdominal aorta in the axial plane crossing the LKV was (16.40±5.10) mm in controls,and all decreased in 4 NCS patients whose LKV was obviously compressed.The average ratio of expansion to stenosis caliber of the LKV was 4,5 in 4 NCS patients,whereas 1.4 in the controls.Conclusion 3D-CE MRA can display relation between abdominal aorta,SMA and LKV,thus exactly diagnose the nutcracker syndrome.
