Objective To explore clinical the characteristics and countermeasures of osteoporotic vertebral fractures treated with percutaneous vertebroplasty. Methods From March 2005 to March 2008,64 patients (totally 86 vertebra) with osteoporotic vertebral fractures undergoing percutaneous vertebroplasty were retrospectively analyzed. The level of fracture was between T5 to L5. The symptomatic fractured vertebrae were determined with combination of regional pain, X-rays and MR images. The postoperative effect were evaluated by the visual analog score (VAS) and Oswestry disability index (ODI). Results All the patients were followed up 12 - 23 ( 13.40 ± 1.03 ) months. The VAS decreased from (8.3 ± 1.2) scores to bdfore surgery (2.3 ± 1.4) scores after surgery and to (2.5 ± 1.1 ) scores at the last follow-up time(P ＜ 0.01 ). The ODI decreased from (62.0 ± 2.3 ) scores before surgery to (23.1 ± 2.5 ) scores after surgery and to ( 26.3 ±2.4) scores at the last follow-up time (P ＜0.01). The back pain of all patients were relieved to different degrees postoperatively. No severe complications including pulmonary embolism occurred. Conclusions The key point is to find the symptomatic fractured vertebrae not only based on preoperative X-rays but also the MR images, especially fat-compressing MR images. Only when the fractured vertebrae demonstrate low intensity on T1WI MR image and high intensity on T2WI or fat-compressing MR image can be considered new fractures. The injection should reach the new fractured part and if necessary the bilateral approaches should be considered and the injection can be separated for several steps in multi-segments fracture. PMMA should be injected after the bone cements are solid enough so as not to develop complications such as pulmonary embolism.

Objective Increasing evidence supports the involvement of autophagy in the etiopathology of autoimmune diseases.Systemic lupus erythematosus (SLE) is a potentially fatal autoimmune disease characterized by production of multiple autoantibodies through poorly understood mechanism.In order to explore the role of autophagy in the development of SLE,the expression of autophagy related gene microtubule-associated protein 1 light chain 3 (MAPLC3) in peripheral blood mononuclear cells (PBMCs) was measured in patients with SLE.Methods The mRNA levels of LC3 in PBMCs from 56 SLE patients and 45 healthy individuals were detected by real-time quantitative polymerase chain reaction (qPCR) technique.Autophagy in PBMCs was also determined by flow cytometry (FACs) in 20 SLE patients and 15 healthy controls.The correlation between LC3 mRNA expression and disease activity of SLE (SLEDAI) was then analyzed.Results The mRNA level of LC3 (RQ) in SLE patients was obviously downregulated compared with that in healthy population (1.30 ± 0.10 vs 1.35 ± 0.09; P =0.029),paralleled with the decreased autophagy rate detected by flow cytometry in PBMCs of SLE patients [(2.21 ± 1.07) ％ vs (9.91 ±4.01) ％ ;P =0.047].Moreover,LC3 mRNA expression level was negatively correlated with SLEDAI (r =-0.337,P =0.023).However,when the clinical features of 27 SLE patients with decreased LC3 mRNA expression (RQ ＜ 1.351) were compared with those of other 29 SLE patients with normal or high LC3 mRNA expression (RQ ＞ 1.351),increasing rates of arthritis,serositis,hematological abnormalities were noted in patients with decreased LC3 mRNA expression yet without statistically significance.However,there was a significant difference between two groups in the incidence of renal involvement (P =0.028).Conclusion The impaired autophagy due to dowrnregulated LC3 mRNA level in SLE patients indicates that autophagy plays a role in mediating the occurrence and development of SLE.

Real-time PCR and Western blotting were applied to detect the gene and protein expression of Lhx8 in each group.The choline acetyltransferase ( ChAT)/Lhx8 double labeled cells in subgranular zone ( SGZ) of hippocampus in each group were detected by immunofluorescence .Results The expression of Lhx8 gene and protein in the transected , NGF group and especially in the transected combined with NGF group was obviously higher than in the control group .The number of ChAT/Lhx8 double labeled cells in the NGF group and the transected combined with NGF group was obviously more than in the control group and transected group . Conclusion The hippocampal neuroregeneration which induced by NGF intracerebroventricular injection was associated with the higher expression of Lhx8.

Objective To explore the clinicopathological features, diagnosis and therapy for pancreatic mutinous noncystic adenocareinoma(MNAC). Methods Eleven MNAC cases treated in our hospital were studied retrospectively. The clinical and pathologic data were reviewed. Results Of the 11 patients, 6 were male and 5 were female. The age ranged from 47 to 76 years with average of 60. 5 years.The main complains included upper abdominal discomfort in 8 cases, abdominal mass in 1 case and jaundice in 2 cases. CA199 serum test was positive in all patients and 5-fold high above normal value in 6 cases. The preoperative radiography of MNAC was usually not specific. Tumors located in the head in 5 cases and in the body and tail of the pancreas in 6 cases. The diameter of the tumor was 4 - 11 cm with average of 6. 5 cm.All cases underwent operation, with radical resection in 2 cases. Liver or abdominal metastasis was found in 5 cases. Postoperative immunohistochemistry showed that MUC-1 was negative in all patients. MUC-2,PCNA and Ki-67 were positive in all patients. All 9 cases that were followed-up died within 5 -22 months,with an average survival time of 10 months. Conclusions The diagnosis of MNAC depends on pathology. Its prognosis is poor.

Objective To investigate the effects of leukotriene in children with respiratory syncytial (RSV)viral bronchiolitis.Methods The blood and sputum levels of Ieukotriene were detected in 33 cases diagnosed RSV bronchiolitis and 12 cases which were diagnosed pneumonia without RSV infection.Thirty-three cases of bronchiolitis were devided into mild-moderate group(n =22)and severe group(n =11)according to the lowell score.Results The blood and sputum levels of leukotriene in mild-moderate group,severe group,and pneumonia group were(76.96 ± 28.19)pg/ml,(103.53 ± 16.85)pg/ml,(18.14.± 7.49)pg/ml;(31.83 ± 19.14)pg/ml,(67.11 ± 15.11)pg/ml,(6.81 ± 2.90)pg/ml in acute period,and(36.04 ±16.38)pg/ml,(52.27 ± 17.03)pg/m l,(18.14 ± 7.49)pg/ml of serum in recovery period.There were significant differences among three groups(F =48.09,P ＜ 0.001 ; F =15.50,P ＜ 0.001 ; F =44.43,P ＜0.001).After treatment,the blood levels of leukotriene were significantly decreased,but were still higher than that of pneumonia group(P ＜ 0.05).Conclusion The blood and sputum levels of leukotriene increase in children with RSV bronchiolitis,which is related with the severity of bronchiolitis.

Objective To evaluate the influence of head anteflexion on airway sealing pressure during intermittent positive pressure ventilation(IPPV) with ProSeal laryngeal mask airway (PLMA) with an esophageal vent.Methods Fifty ASA Ⅰ or Ⅱ patients (20 males and 30 females), aged 18-51 ye are, weighing 50-70 kg and scheduled for elective plastic surgery under general anesthesia, were enrolled in this study. Anesthesia was induced with fentanyl 2 μg/kg, propofol 2 μg/kg and vecuromium 0.1 mg/kg. PLMA with an esophageal vent was inserted at 2 min after intravenous vecuronium injection.The airway sealing pressure, the anatomic position of the cuff and the efficacy of positive pressure ventilation were checked in the neutral and anteflexed head positions with the cuff deflated and inflated to an intracuff pressure of 60 cm H2 O, respectively.Results The lungs were better ventilated in the head anteflexion position than in the head neutral position whether the cuff was deflated or inflated. There was no significant difference in the volume of air required to achieve an intracuff pressure of 60 cm H2O between the two head positions ( P＞ 0.05). The airway seating pressure increased from (27 ± 6) cm H2O in the head neutral position to (33 ± 6) cm H2O in the head anteflexion position, with no significant difference between them ( P＞ 0.05). The expired tidal volume and the peak inspiratory pressure during IPPV were (496 ± 81 ) ml and (14.3 ± 1.9) cm H2O respectively in the head neutral position and (496 ± 81 ) ml and ( 14.5 ± 2.1 )cm H2O respectively in the head anteflexion position.Conclusion Head anteflexion can significantly improve airway sealing but does not affect the anatomic position of the cuff.Appropriate head anteflexion is a simple and effective way to improve IPPV when the airway sealing pressure is inadequate in the head neutral position.

Objective To investigate the expression of human glucocorticoid-induced tumor necrosis factor receptor(hGITR)in synovial and cartilage tissue of patients with rheumatoid arthritis(RA),and analyze their relationships with the severity of synovial inflammation in RA.Methods Expression of hGITR in synovial and cartilage biopsy material of 16 RA patients,9 osteoarthritis(OA)patients,4 contmIs were detected in situ by immunohistochemical technique and the results were analyze then.Results hGITR was strongly expressed in the vascular endothelial cells and inflammatory cells in RA and hGITR positive cells could be detected in approximately 69%of RA synovial cells.Significant differenee Was foand in hGITR expression between RA patients and control group(P<0.01).hGITR was less expressed in the cartilage than the synovial in RA.No significant difference was found in expression in the cartilage tissue expression between RA patients and the control group.Significant difference Was found in hGITR expression between synovial and cartilage in RA.Furthermore.the hGITR positive cells in synovial tissues were also found to correlate significandy with the severity of synovial inflammation in RA patients(r=0.895,P<0.01).Conclusion These results suggest that the abnormal expression of hGITR in the synovial my bean important mechanism leading to the synovial destruction found in RA.
