BACKGROUND: At present, more and more scholars pay attention to the influence of spine and pelvis sagittal balance on the quality of life of patients. Postoperative changes in spine imaging parameters fol owing corrective osteotomy for lumbar degenerative kyphosis have not been reported. OBJECTIVE: To evaluate postoperative changes in sagittal balance fol owing corrective osteotomy for lumbar degenerative kyphosis. METHODS: We retrospectively analyzed 35 consecutive lumbar degenerative kyphosis patients treated with posterior osteotomy fixation in the First Affiliated Hospital of Xinjiang Medical University from February 2012 to December 2014. Imaging parameters were measured before fixation, immediately after fixation and during final fol ow-up. RESULTS AND CONCLUSION: (1) There were significant differences between preoperative and postoperative parameters except for pelvic incidence angle (P < 0.05). (2) There were significant differences between postoperative and last fol ow-up parameters except for Cobb angle, pelvic incidence angle, thoracic kyphosis angle and the thoracolumbar kyphosis (P < 0.05). (3) Pelvic tilt angle was negatively correlated with lumbar lordosis after fixation (r=-0.610, P < 0.001). Thoracic kyphosis was positively correlated with lumbar lordosis (r=0.598, P < 0.001). (4) Results suggested that lumbar sagittal contour can be significantly improved by corrective osteotomy for lumbar degenerative kyphosis. Simultaneously, reciprocal changes in the adjacent areas such as thoracic spine and pelvis occur to adapt to the new sagittal balance.

BACKGROUND:Spinal tuberculosis seldom involves cervical vertebra. The application of anti-tuberculosis drug has slight effects on patients combined with nerve dysfunction and severe vertebral destruction, which results in unstable cervical vertebra. OBJECTIVE: To evaluate biocompatibility of graft and host after one-stage anterior debridement graft fusion and internal fixation in the repair of adult cervical tuberculosis. METHODS: A total of 14 patients who suffered from cervical tuberculosis were admitted into Department of Spinal Surgery, First Affiliated Hospital, Xinjiang Medical University between May 2010 and June 2012. They underwent Zephir anterior cervical plate for one-stage anterior debridement graft fusion and internal fixation. RESULTS AND CONCLUSION:Compared with pre-fixation, erythrocyte sedimentation rate, C-reactive protein and visual analog scale score were lower in final folow-up (P < 0.05), and Japanese Orthopaedic Association score increased (P < 0.05). Except that Frankel grade recovered to grade D from grade C in one case, Frankel grade did not alter in the remaining patients. Compared with pre-fixation, Cobb angle was apparently shortened in seven patients with kyphosis. Folowing internal fixation, bone trabecula was visible between the vertebral body and graft region after fixation. No displacement, bone resorption, nonunion or pseudoarthrosis occurred. Neck pain and limited function relieved or disappeared to different degrees after fixation. These findings suggest this method can effectively treat cervical tuberculosis. Moreover, the biocompatibility of the plate and host is good.

Objective In order to study the difference of depression-like behaviours among three widelyused stress models in rats.Methods The new-born Spragne-Dawley rats were randomly divided into maternal deprivation(MD) group(n=27),chronic mild stress(CMS) group (n=29),dual stress(DS) group ( n=31 ) and control (C) group ( n =30) on postnatal day 1.MD rats only received maternal deprivation.CMS rats only received chronic mild stress when 10 weeks old.DS rats received both maternal deprivation and chronic mild stress.Control rats received no experimental handling.Behavior tests including forced swimming test and sucrose consumption which were carried out to evaluate rats' depression-like behaviors in the thirteenth weeks.The extend time of floating and sucrose preference ratio should be recorded in the forced swimming test and sucrose consumption test respectively to reflect the behavior of helplessness and anhedonia of rats.Results In the forced swimming test,the extend floating time of MD group( 119.30 ± 65.56) s,CMS group ( 145.00 ± 80.24) s and DS group ( 170.03 ±61.75 )s were longer than the control group(81.14 ± 52.40)s (F =11.53,P ＜ 0.01 ).In the sucrose consumption test,the MD group(0.32 ± 0.22) had a low sucrose consumption.The comparison of the MD group and CMS group (0.43 ± 0.28 ) to the control group (0.54 ± 0.28 ) had significant differences (F =4.33,P ＜ 0.01 ).In these four groups,no sexual difference was found in the forced swimming test and sucrose consumption test ( all P ＞ 0.05 ).Conclusion The results suggest that MD,CMS and DS may induce some kind of depression-like behaviors in rodents such as anhedonia or the behavior of helplessness and the depression-like behaviors induced by different stresses are similar in male and female individuals.

OBJECTIVETo explore the theory of "Fei and Dachang being interior-exteriorly related" and the pathogenesis of lung injury by observing changes of inflammatory cytokines and oxygen free radicals in ulcerative colitis (UC) rats.

METHODSTotally 50 healthy male Wistar rats were randomly divided into two groups, the normal control group and the model group, 25 rats in each group. The UC model was established by allergizing colon mucosa combined with TNBS-alcohol (50%) enema. Another 25 rats were recruited as the normal control group. At week 2 and 4 after modeling, the pathomorphological changes of the lung were observed. Furthermore, the contents of tumor necrosis factor alpha (TNF-alpha) and IL-1beta were determined by ELISA. The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluated with colorimetry.

RESULTSCompared with the normal control group, the pathomorphology of the lung tissue in the model group appeared abnormal at week 2 and 4. Compared with the normal control group, levels of TNF-alpha, IL-1beta, and MDA in the lung tissue significantly increased in the model group (P < 0. 01) and the activities of SOD significantly decreased (P < 0.05, P < 0.01).

CONCLUSIONTNF-alpha, IL-1beta, SOD, and MDA might be common material bases for the large intestine involved in lung disease of UC patients, thus providing a modern scientific basis for the theory of Fei and Dachang being interior-exteriorly related.

Objective To analyzed the CT features of struma ovarii(SO).Methods The clinical data and CT features of eleven patients with pathologically proved SO were retrospectively analyzed.CT features were compared with pathological results.Results(1)All tumors were unilateral.On non-enhanced CT,the lesions presented as well-defined irregular masses,which were cystic-solid(n=6,54.5%)or cystic(n=5,45,5%).(2)The cystic portions presented as well-defined,multiple,various size,and there were entire cystic walls with smooth inner wall.The tumors(63.6%)showed a high at attenuation lesions in the cyst portion of the mass on precontrast scans and the attenuation ranged from 72.3 to 113.5 Hounsfield units(HU)in 7 cases.The solid portions showed irregular tissue density,and were often distributed in the cysts.After contrast administration,the cystic portions showed no enhancement,the solid portions marked enhancement,and the cystic walls demonstrated no moderate,or marked enhancement.(3)The tumors(72.7%)showed stippled calcification in solid portions and(or)cystic wall in 8 cases.(4)The tumors(27.3%)accompanied with mature cystic teratomas,and showed fat density in 3 cases.(5)The tumors(27.3%)accompanied a great of ascites and pleural liquid.Conclusion CT characteristics of SO might be of great value for the diagnosis.

Objective To investigate the safety and effectiveness of ultrasound-guided paravertebral anaes-thesia combined with propofol in the thoracoscopic sympathectomy. Methods Total 63 male and 59 female patients with hyperhidrosis were recruited. The patients were equally divided into two groups:group A and C. Patients in group A received ultrasound-guided paravertebral anaesthesia combined with propofol. Patients in group C received general intravenous anesthesia with endotracheal intubation. The heart rate (HR),mean arterial pres-sure(MAP)and the oxygen saturation(SpO2)at the time of entering the operating room(T0),completing anesthe-sia(T1),incising the skin(T2),cutting the T4 sympathetic trunk(T3),completing the operation were record-ed. The awake time after operation ,VAS score after operation and postoperative throat discomfort were also record-ed. Results The two groups successfully completed the surgery. There were no significant differences of the HR , MAP and SpO2 at T0-T4 between the two groups. There were significant differences of the awake time after opera-tion,postoperative feeding time and hospitalization expenses. The VAS score after operation of group A were better than group C(P<0.05)at T2 h,T4 h,T8 h,and T12 h. There was no significant difference of VAS score at T24 h between the two groups. Conclusion Ultrasound-guided paravertebral anaesthesia combined with propofol can pro-vide a safe and effective approach for patients receiving the thoracoscopic sympathectomy.

Objective To evaluate the safety of modified sputum induction in moderate to very severe COPD during exacerbation. Methods Ninety patients with moderate, severe or very severe COPD during exacerbation (27 with type Ⅰ and Ⅱ respiratory failure,18 with coronary heart disease, 38 with tachycardia) were chosen as research subjects. All the patients underwent induced sputum. During induction , all patients were given electrocardiographic monitoring and pulmonary function check every 5 minutes and FEV1, HR, SpO2 in the process of testing were recorded. Results Ninety patients underwent 224 sputum inductions progress, 222 were safety. Qualified sputum samples were collected for 216 times, sputum induction was successful in 96.43% of occasions. Heart rate rising and SpO2 reducing during sputum induction mainly occurred in the beginning 5 minutes, FEV1 did not change in the whole process. Conclusion Modified sputum induction can be safe through closely monitoring in patients with moderate-to-very severe COPD with exacerbation, even with type Ⅰ or typeⅡ respiratory failure. But the risk of sputum induction will increase if patients with coronary heart disease and tachyarrhythmia, especially within beginning 5 minutes of sputum induction.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.

METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.

RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).

CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

The study was conducted to explore the response of growth and yield of Tulipa edulis to flower bud removal and artificial pollination. And flower bud removal and artificial pollination were carried out in the squaring period and bloom stage respectively. The morphological index and biomass indicators were determined and the yield was counted in harvest time. Result showed that flower bud removal was beneficial to the growth of T. edulis, resulting in increasing growth index, biomass as well as the yield of bulb. The diameter and dry weight of T. edulis fruit by artificial pollination were increased significantly compared with the control. Seed setting percentage increased to 100%, and the number of seed as well as the single grain weight increased by 69.03% and 16.48%, respectively, which did not significantly affect the bulb production. In conclusion, Flower bud removal treatment accelerates bulb biomass increase, so as to improve its yield. Artificial pollination raised significantly seed setting percentage, seed number as well as the single grain weight.
