Although the development of diagnosis and treatment about degenerative scoliosis has improved significantly,it still remains controversial about how to select appropriate surgical methods.The goal of this review is to raise awareness and stimulate attention on the correlation between clinical manifestation and spinal deformity,which is one of the key factors to affect the surgical outcomes on the opinion of more and more researchers in the past 20 years.When an adult spinal deformity is not the source of symptoms and the clinical symptom is outside of curve,symptomatic relief may be provided through limited decompression.If thoroughly decompression,it will be enough to combine with short segment fixation.However,while an adult deformity is the source of symptoms and the clinical symptoms is within the curve,the options are typically limited decompression on the basis of good stability,otherwise,it will be the only consideration of decompression combined with long segment fixation.

BACKGROUND:Skeletal muscle fiber damage that is induced by prolonged or high-intensity exercise directly cause muscle injury. OBJECTIVE:To propose the existence of a relationship between delayed onset muscle soreness and muscle satel ite cel s after skeletal muscle injury from the objective reality. METHODS:A retrieval of CNKI and PubMed databases was done for relevant literature published from February 1961 to February 2015 using the keywords of“delayed onset muscle soreness;skeletal muscle injury;satel ite cel s, skeletal muscle;myogenic regulatory factors”in Chinese and English, respectively. Final y, 59 articles were included to explore the mechanism of skeletal muscle injury accompanied by delayed onset muscle pain. RESULTS AND CONCLUSION:Skeletal muscle micro-injury mainly refers to ultrastructural destroy and metabolic disorders, involving muscle cel membrane, cytoskeleton, sarcomere and mitochondria, thereby leading to skeletal muscle contraction dysfunction that is often accompanied with delayed onset muscle soreness. Eccentric exercise can cause the severest microdamage to the skeletal muscle fibers. The occurrence of delayed onset muscle soreness can stimulate the secretion of growth factors from skeletal muscle satel ite cel s to a certain extent, and the time series of delayed onset muscle soreness triggered by sustained high-intensity eccentric exercise has a certain correlation with the time series of the proliferation of skeletal muscle satel ite cel s.

Aim To explore the effect and mechanism of atorvastatin on lipopolysacchairde (LPS) inducing the expression of inhibitor of nuclear factor ?B? (I?B?) in human vascular endotheliar cells. Methods The human vascular endotheliar cell line ECV304 was cultured and divided into five groups as control group, LPS group, and low, moderate or high does atorvastatin groups. After incubated with different densities atorvastatin, the three atorvastatin groups and LPS group were stimulated with LPS 30min. Then the activation of I?B? was observed with immnofluorescence. The proteins expressions of I?B? and phosphorylated I?B? were detected with western blot. The ex-pression of I?B? mRNA was examined with reversetranscription-polymerase chain reaction. Results Atorvastatin could inhibit the translocation of p65 to the nucleus and reduce the phosphorylation and degradation of I?B? in a dose-dependent manner. The high density atorvastatin could increase the expression of I?B? mRNA. Conclusion The atorvastatin can inhibit the activation of nuclear factor ?B by regulating the expression and degradation of I?B?.

Objective To study the hemodynamic changes of rabbit VX2 liver tumors before and after ethanol injection by perfusion imaging of MSCT and investigate the correlation between perfusion parameters and microvessel density (MVD). Methods All of 15 Japanese long-ear white rabbits were divided into control group and experiment group. All rabbits were inoculated with VX2 liver tumor. Perfusion imaging of MSCT scans were conducted in 5 rabbits in the control group on the 14 th day after VX2 tumor inoculation, and the borders of the tumors were stained with immunohistochemical stains, and MVD was measured by anti-CD34. Perfusion imaging of MSCT scans were conducted in all 10 rabbits in the experiment group on the 14 th day after VX2 tumor inoculation. Then absolute alcohol was injected into the tumors by laparotomy. CT scans were conducted 3 and 30 days after absolute alcohol injection, and the borders of the tumors were stained immunohistochemically, and MVD was measured by anti-CD34. The differences of perfusion parameters such as hepatic blood ( BF), hepatic blood volume (BV), mean transit time ( MTT),permeability of capillary vessel surface (PS), and hepatic arterial fraction (HAF), hepatic arterial perfusion (HAP) were compared to evaluate the liver hemodynamic changes. Statistical repeated measurement t test, correlation analysis were performed. Results BF of border of the tumor between pretreatment, 3 days after ethanol injection and 30 days after ethanol injection were ( 280. 62 ± 59. 87 ),(322.03 ± 86. 94 ), ( 177.05 ± 75.96) ml · min -1; HAF were 0. 59 ± 0. 08, 0. 89 ± 0. 12, 0. 23 ± 0. 07;HAP were ( 189. 26 ± 25.46), ( 251.57 ± 31.78 ), (40. 90 ± 5.17 ) ml · min - 1 · ml - 1. HAP increased significantly after ethanol injection 3 days ( P < 0. 05 ); BF, HAF, HAP decreased significantly 30 days after ethanol injection compared with 3 days after ethanol injection ( P < 0. 05 ); BF, HAF, HAP decreased significantly 30 days after ethanol injection compared with pre-treatment ( P < 0. 05 ). It showed positive correlation between BF, PS, HAF, HAP and MVD (r=0. 916, 0. 726, 0. 870, 0. 889; P <0. 05). MVD decreased significantly compared with the control group (43.9 ± 4. 0)/HP 30 days after ethanol injection (21.8±3.5)/HP (t = 12.271, P <0.05). Conclusion Perfusion imaging of MSCT can detect the hemodynamic changes in rabbit VX2 liver tumors, and also in tumors before and after ethanol injection. CT perfusion can take the place of MVD to evaluate the tumor angiogenesis.

Objective To analyze the relationship between daytime sleepiness and oxygen desaturation in the male eldcrly with obstructive sleep apnea /hyponea syndrome (OSAHS).Methods 147 male elderly (aged 60-80 years) with OSAHS in our sleep laboratory from March 2008 to February 2011 were divided into daytime sleepiness and daytime non-sleepiness groups. Epworth sleeping scale (ESS) and polysomnography (PSG) were employed to detect the degree of sleepiness.Oxygen desaturation were evaluated by oxygen desaturation index (ODI),average and minimum blood oxygen,time percentage of 90% oxygen desaturation (CT90). Resulls There were significant differences between the two groups in body mass index (BMI) (t=4.157),ODI (t=-10.063),average (t=5.800) and minimum (U=916) blood oxygen,CT90(U=887)and apnca/hypopneaindex (AHI) (t =-11.361) (all P<0.001).ESS scores were related with desaturation parameters of ODI,average and minimum blood oxygen and CT90 (r=0.683,-0.450,-0.583,0.507,all P<0.001).ODI was correlated with average and minimum blood oxygen and CT00 (r=-0.628,-0.763,0.689,all P<0.001).Among parameters of oxygen desaturation,only ODI had influence on ESS scores (odds ratio=1.11,95%CI:1.07 1.15),The sensitivity and specificity predicting daytime sleepiness at ODI ≥23 times/h were about 79.2% and 84.3%,respectively.Conclusions Daytime sleepiness is associated with oxygen desaturaion and may be predicted by ODI through which average and minimum blood oxygen and CT00 are related with daytime sleepiness in the male elderly with OSAHS.
