OBJECTIVETo explore the clinical effects of Dynesys system for the treatment of multiple segment lumbar degenerative disease.

METHODSA total of 28 patients with lumbar degenerative disc disease treated with Dynesys system from December 2008 to May 2011 were retrospectively reviewed. There were 16 males and 12 females, aged from 27 to 75 years old with an average of 49.1 years. Thirteen patients with multiple segmental lumbar intervertebral disc protrusion, including L3-L5 in 7 cases, L2-L4 in 1 case and L4-S1 in 5 cases. Fifteen patients with multiple segmental lumbar spinal stenosis, including L3-L5 in 10 cases, L4-L5 in 4 cases and L2-S1 in 1 case. The symptoms of lumbago and (or) intermittent claudication in all patients were treated with conservative treatments for more than 6 months and these methods did not work. Visual analogue scale (VAS) was used to analyze the lumbar and leg pain, imaging data were used to measure the intervertebral space height and intervertebral motion of fixed segment and upper adjacent segment, Oswestry Disability Index (ODI) was used to evaluate the clinical effect.

RESULTSAll operations were successful and the patients were followed up from 38 to 65 months with an average 50.6 months. At final follow-up, ODI and VAS of the low back pain and leg pain were (25.10±6.52)%, (1.25±0.70) points and (1.29±0.89) points, respectively and were decreased compared with preoperative (P<0.05). Postoperative intervertebral space heights were increased and intervertebral motions were decreased in fixed segment compared with preoperative (P<0.05). There were no significant differences in intervertebral space heights and intervertebral motions of upper adjacent segment between preoperative and postoperative (P>0.05).

CONCLUSIONDynesys system may obtain long-term clinical curative effect in treating multiple lumbar degenerative disease. It can partially preserve the intervertebral motions of the fixed segments, have little effect on adjacent segments. The long-term clinical effect of Dynesys still need longer time follow-up observation.

Objective To investigate the role of autophagy and synaptophysin (SYP) in cognitive impairment in de?pressed rats receiving electroconvulsive shock (ECS). Methods Clean and healthy adult male Sprague-Dawley rats were acclimatized to a standard laboratory environment for 7 days. The chronic unpredictable mild stress (CUMS) was used to establish the rat model of depression. Behavior tests were conducted before and after CUMS to evaluate the depression and cognition level of rats. After establishment of the model, 24 rats were randomly divided into ESC group (group E) and depression group (group D) with 12 rats in each group. The rats in group E were administered 80 mg/kg of propofol (10 mg/mL) by intraperitoneal injection, followed by ECS treatment. The rats in group D were administered propofol by intra?peritoneal injection, followed by sham-ECS treatments. The above interventions were conducted daily for 7 consecutive days. After the interventions, rats underwent behavior tests as before. Subsequently, rats were killed and specimens were collected for measurements. Immunohistochemistry was performed to examine autophagy markers such as Beclin 1 and LC3Ⅱand ELISA was used to detect SYP in the hippocampus. Results Group E after ECS significantly increased the percentage of sucrose preference (68.2%±8.7%), rearing times (7.0±1.9), total horizontal distance [(569.5±70.0) cm], es? cape latency [(21.9±5.3)s] and space exploration time [(20.5±3.9)s] compared with group D or group E before ECS. There was no significant difference in these index between groups before ECS or in group E between before and after ECS(P>0.05). Compared with group D, group E had upregulated protein expression levels of Beclin 1 and LC3Ⅱin CA1, CA3, DG as well as the area near the hippocampus and increased SYP contents (P<0.05). Conclusions Cognitive impairment in depression rats following ECS correlates with activated autophagy and increased SYP by ECS.

Objective To study the mutagenic action of antiepileptic drugs(AEDs), and find an effective way to prevent the mutagenesis induced by AEDs,by observing the effects of AEDs on serum folic acid(FA) level and sister chromatid exchange (SCE) frequency in epileptic children.Methods Ninty epileptic children were divided into different groups on the basis of the different drugs they had taken, then detected the two indexes at different time points.Results The serum FA level and SCE frequency of the patients significantly decreased and increased after they took carbamazepine (CBZ) and valproic acid (VPA)respectively. The two indexes went back respectively when supplied with FA.Conclusions Both CBZ and VPA possess mutagenic action, yet nitrazepam does not.FA may help repair the chromosome damage and reduce the mutagenesis effects.

Objective To investigate the expression of adamalysin-12 (ADAM-12) and PCNA in human bladder carcinoma and to investigate their correlation with different grades and stages of bladder cancer.Methods Biopsies of 15 normal bladder and 43 bladder tumors were analyzed.Immunohistochemistry was conducted to detect the expression of ADAM12 and PCNA in the biopsies.Results Postive expression signals of ADAM12 were detected significantly higher in the bladder cancer biopsies than that in the normal ones (P = 0.010).Those with lower histological grade had a higher expression level of ADAM-12 compared to the higher histological grades (P ＜0.001 ).Positive expression signals of PCNA were detected significantly higher in the bladder cancer biopsies than that in the normal ones (P = 0.026).Those with lower histological grade had a higher expression level of PCNA (P =0.014).There was a positive correlation between the expression of ADAM-12 and PCNA in bladder cancer (r =0.997,P ＜ 0.001 ).Conclusions The overexpression of ADAM-12 and PCNA in the biopsies of bladder tumors shows that protein expression of ADAM-12 and PCNA correlated with tumor stage and grade.Furthermore,ADAM-12 may be a promising biomarker of bladder cancer in the clinical implication.

OBJECTIVETo evaluate the clinical effects of dynamic neutralization system (K-Rod) in treating multisegmental lumbar degenerative disease.

METHODSFrom October 2011 to October 2013, 20 patients with multisegmental lumbar degenerative disease were treated with dynamic neutralization system (K-Rod). There were 8 males and 12 females with an average age of 45.4 years old (ranged from 31 to 65) and an average course of 3.8 years (ranged from 9 months to 6.25 years). All patients had the history of low back and legs pain. Among them, 10 cases were far lateral lumbar disc herniation, 7 cases were lumbar spinal stenosis, 3 cases were lumbar spondylolisthesis (degree I in 2 cases and degree II in 1 case). Every patient had only one responsible segment which causing the symptom would have to be rigidly fixed during operations, and the adjacent intervertebral disc of the responsible segments at least 1 segment has already obvious degenerated. All patients underwent the operation to relieve compressed nerves and reconstruct spinal stability with K-Rod system (the responsible segments were fixed with interbody fusion, and the adjacent segments were fixed with dynamic stabilization). Visual analogue scale (VAS), Japanese Orthopaedic Association Scores (JOA) and Oswestry Disability Index (ODI) were used to evaluate the clinical effects. Imaging data were used to analyze the range of motion (ROM), intervertebral disc height and intervertebral disc signal (according to modified Pfirrmann grading system) in degenerative adjacent segment.

RESULTSAll patients were followed up for more than 1 year, and preoperative symptoms obviously relieved. There were significant differences in VAS, JOA, ODI between preoperative and postoperative (postoperative at 1 week and 1 year) (P<0.05). Radiological examination showed that all responsible segments had already fused, and no looseness, displacement and breakage of internal fixations were found. Postoperative at 1 year, the ROM of adjacent segments were decreased (P<0.05). There was no significant difference in intervertebral disc height between preoperative and postoperative at 1 year (P>0.05). According to modified Pfirrmann grading system to classification for the 25 disks of adjacent segment, 8 disks (32%) got improvement, 15 disks (60%) got no change and 2 disks (8%) got aggravation at 1 year after operation.

CONCLUSIONDynamic neutralization system (K-Rod) combined with interbody fusion could obtain short-term clinical effects in the treatment of multisegmental lumbar degenerative disease.

OBJECTIVETo introduce practical diagnostic criterion of blood stasis syndrome (BSS), and to evaluate its reliability and validity.

METHODSBy referring to three diagnostic criteria of BSS [practical diagnostic criterion of BSS (criterion A), diagnostic criterion of BSS in 1986 (criterion B), Consensus of Integrative Medicine on BSS Diagnosis in 2011 (criterion C)], 712 patients from different departments of Xiyuan Hospital were recruited. The reliability of criterion A and its consistency with the other two criteria were assessed using Kappa coefficient. A Bayesian approach was also employed to assess the sensitivity and specificity of criterion A.

RESULTSAccording to the consistency check, criterion A presented good consistency when used by different researchers (the diagnostic accordance rate was 91. 96%, Kappa =0. 82, P <0.001). Meanwhile, there was an acceptable diagnostic consistency among the three diagnostic criteria. Bayesian estimation suggested that criterion A had higher sensitivity but similar specificity, as compared with criterion B or criterion C. Compared with criterion B [the median of sensitivity and specificity were 0. 762 (95% Cl: 0. 731 -0. 790) and 0. 902 (95% Cl: 0. 858 -0. 936) respectively, the median of sensitivity and specificity of criterion A were 0. 911 (95% CI: 0. 888 - 0. 930) and 0. 875 (95% CI: 0. 826 - 0. 915) respectively. Estimating the difference between criterion A and B, the median of sensitivity and specificity were 0. 149 (95% CI: 0. 112 -0.184) and -0. 026 (95% CI:-0. 085 -0. 033) respectively. Compared with criterion C [the median of sensitivity and specificity were 0. 831 (95% Cl: 0. 804 -0. 857) and 0. 892 (95% CI: 0. 848 - 0. 926) respectively], the median of sensitivity and specificity of criterion A were 0. 912 (95% CI: 0. 889 -0. 932) and 0. 880 (95%CI: 0. 833 - 0.919) respectively. Estimating the difference between criterion A and C, the median of sensitivity and specificity were 0. 081 (95% CI: 0.047 - 0.114) and -0.011 (95%CI: -0.070 -0.046) respectively.

CONCLUSIONCompared with criterion B and C, criterion A not only had better reliability, but also could significantly improve the sensitivity without obviously lowering the specificity.

OBJECTIVETo study the epidemiological characteristics of Mycoplasma pneumoniae pneumonia (MPP) in children, and to provide a basis for diagnosis and treatment.

METHODSThe serum level of Mycoplasma pneumoniae antibody IgM (MP-IgM) was measured by enzyme-linked immunosorbent assay for 3156 hospitalized children with confirmed community acquired pneumonia from February 2011 to January 2012. The antigens of seven respiratory viruses were detected in the nasopharyngeal secretions of children with MPP.

RESULTSMP-IgM was detected in 427 of the 3156 patients, with a positive rate of 13.53%. The infection rate in female patients was significantly higher than in male patients (16.30% vs 11.70%; P<0.01). The MP-IgM detection rates were 3.6%, 12.5%, 19.2%, and 24.4% in children aged under 1 year, 1-3 years, 3-6 years and 6-14 years respectively (P<0.01), and the total MP-IgM detection rate in children aged under 3 years was significantly lower than in children over 3 years (P<0.01). The MP-IgM detection rate varied with the seasons and was significantly higher in summer and autumn than in winter and spring (19.18% vs 9.61%; P<0.01). Of the 427 MP-IgM-positive children, 60 (14.1%) were infected with respiratory viruses, and the highest proportion of which was respiratory syncytial virus.

CONCLUSIONSMPP is sporadic throughout the whole year, with a higher incidence in summer and autumn. MPP occurs mostly in preschool and school-age children, and there is mixed infection of MP and respiratory viruses.
