Objective To evaluate and compare the presence of the nerve root sedimentation sign in patients with lumbar spondylolisthesis (LS) and lumbar disc herniation(LDH). Methods One hundred and fifty-one patients with degen?erative lumbar spinal disease treated by surgery from July 2012 to March 2014 were reviewed retrospectively in Tianjin Hos?pital. All the patients were divided into two groups:LS group (48 cases) and LDH group (103 cases). The clinical outcomes were evaluated by Japanese Orthopedic Association (JOA). The probability of positive sedimentation sign was compared be?tween LS group and LDH group. Correlation between the JOA score and nerve root sedimentation sign were analysed in two groups. Results There was no statistical difference in JOA score between LS group and LDH group (15.83±3.57 vs 16.76± 3.10, t=1.624, P=0.107). A positive sedimentation sign was identified in 39 patients in the LS group (81.25%) but in 65 pa?tients in the LDH group (63.11%). The difference between LS group and LDH group was statistically significant(χ2=5.028, P=0.031). In LS group, JOA scores of patients with positive nerve root sedimentation sign were lower than those of patients with negative nerve root sedimentation sign(15.33±3.50 vs 18.00±3.20, t=2.092,P=0.042);but in LDH group, there was no statistical difference in JOA scores of patients between positive nerve root sedimentation sign and negative nerve root sedi?mentation sign (16.40±3.13 vs 17.37±2.99, t=1.539, P=0.127). Conclusion A positive sedimentation sign also occurs in pa?tients with LDH, but positive nerve root sedimentation sign are more likely to appear in patients with lumbar spondylolisthe?sis who have worse clinical symptoms.

Objective To investigate the relationship between apoptosis of bone marrow cells and tumor necrosis factor-?(TNF-?),Fas/FasL expression in children with aplastic anemia.Methods The concentration of TNF-? in supernatant of cultured bone marrow mononuclear cell(BMMC) was measured by enzyme linked immunosorbent assay.The expression of Fas/FasL,apoptosis ratio of bone marrow CD34+ cell were evaluated by flow cytometry.Results The concentration of TNF-? in supernatant of cultured BMMC in AA group[SAA (27.9?8.20) ng/L;CAA (23.6?6.78) ng/L] increased significantly compared with control group(t=3.432 P0.05).Apoptosis ratio of CD34+ cell in SAA group[(24.6?9.56)%] and CAA group[(20.9?7.32)%] significantly increased compared with control group(t=3.492,3.458 Pa0.05).The concentration of TNF-? was positively correlated with the expression of CD34+ Fas+ in all types AA children(r=0.542 P0.05).Conclusions TNF-? and Fas/FasL system can be involved in inducing CD34+ cell apoptosis.This may contribute to understanding the decreased number of stem cells and bone marrow failure.

[Objective]To investigate the micro-structural alterations within whole brain white matter(WM) in cough syrup abuse addiction patients containing codeine,and to explore the correlation between aberrant WH and abuse time of cough medicine abuse patients.[Methods]Thirty cough syrup abuse addiction patients containing codeine and 30 controls participated in the study. Structural changes in FA and(mean diffusivity)MD were examined in cough syrup abuse addiction patients containing codeine which derived from DTI tractography. Pearson correlation analysis was performed to compare the mean FA value and duration of cough syrup abuse addiction in patients.[Results]Cough syrup abuse addiction patients containing codeine had lower FA value in bilateral anterior limb of internal capsule(ALIC)and higher MD in the bilateral hippocampus and insula,right anterior cingulate cortex(ACC)and superior temporal gyrus,compared to the controls. Cough syrup abuse addiction group also had positive correlation between mean FAvalues and duration of cough syrup abuse addiction in patients.[Conclusion]Micro-structural alterations within whole brain white matter(WM)are found in cough syrup abuse addiction patients containing codeine. This disturbance progresses as duration increases of cough syrup abuse addiction in patients.

Objective To study the human lymphangiogenesis in the early stage of embryo and the expression of forkhead box C2(FOXC2) in human lymphangiogenesis.Methods Lymphatic vessel endothelial haluronic acid receptor-1(LYVE-1) was used as the special marker of lymphatic vessels.Immunohistochemical and double immunofluorescence staining were used to detect the expressions of FOXC2 and LYVE-1 in lymphatic vessels of 85 human embryos of 5 to 11 weeks pregnancy and analyze the features of lymphatic vessel genesis and development.Results LYVE-1 was initially detected in lymphatic vessels in 7-week human embryos.The lymphatic vessel endothelial cells presented brown staining for LYVE-1 in jugular and thoracic region.LYVE-1 was also found to express in human embryonic mesentery lymphatic vessels on the 70th day of pregnancy.The expression of FOXC2 in human embryo was detected prior to that of LYVE-1.At the beginning of the 6th week of pregnancy,FOXC2 was obviously seen in human embryonic mesoderm mesenchyme.FOXC2 expressed not only in human embryonic lymphatic vessels,but also in the vertebral body,cardiovascular wall and other tissues.The expressions of FOXC2 and LYVE-1 were still seen in human embryonic lymphatic vessel endothelial cells after 80 days of pregnancy.Conclusion Lymphangiogenesis of human embryo begins between the 7th and 8th weeks of pregnancy.FOXC2 and LYVE-1 could have some relation with the human embryonic lymphatic vessel genesis and development.

Objective To observe the influence of the short effect antihypertension drugs- nifedipine and medial effect antihypertension drugs- extended release nifedipine on the blood pressure variability (BPV) in essential hypertension(EH). Methods Twenty-five EH patients were underwent 24-hour noninvasive ambulatory blood pressure monitoring (ABPM) and observed their BPV respectively before taking drugs, after taking nifedipine and extended release nifedipine. Meantime,25 normotensive controls (NC) were observed. Results (1)BPV in EH group was higher than that in controlled group and the severer the rise of blood pressure, the more obvious the increase of BPV (P 0.05). Conclusions Nifedipine could increase BPV but extended release nifedipine did not change BPV while they decreased blood pressure. Effect of extended release nifedipine was better than nifedipine in decreasing blood pressure.

Objective To investigate the levels of adiponectin and the relation with insulin and tumor necrosis factor(TNF)- ? in patients with cirrhosis. Methods Adiponectin,insulin and TNF-? levels were determined in 73 patients with cirrhosis and 30 healthy controls, and were correlated with various clinical and biochemical parameters. Meanwhile Child-Pugh liver function was classified. Results Adiponectin was significantly elevated in patients with cirrhosis compared with the control. Adiponectin levels in cirrhosis was correlated positively with insulin and negatively with insulin sensitively index,and did not correlate with TNF-? and liver function.Conclusion Serum adiponectin levels in cirrhosis are significantly elevated. Adiponectin levels do not correlate with TNF-? and liver function, but exclusively insulin and insulin sensitivity index.

ObjectiveTo investigate the distribution of thethymidylate synthase (TS) gene polymorphisms inChinese femaleHan-nationality breast cancer patients,including tandemrepeat polymorphisms in the enhancer region ( ER), 6 bp deletion/insertion (del6/ins6) polymorphism in the 3′untranslated region (3′-UTR) and G→C single-nucleotide polymorphism (SNP). The association of TS gene polymorphism with pathological results was retrospectively analyzed.MethodsThis study included 83 breast cancer patients who received no preoperative chemotherapy. The polymorphisms of TS, ER and TS 3′2UTR were determined by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method.Results ( 1 ) Of the 83 patients, the frequencies of the TSER 3R/3 R, 2R/3 R and 2R/2R were 68.7％ ,27. 7％ and 3. 6％, respectively; (2) Due to existence of the G→C single nucleotide polymorphism,TSER genotypes were divided into 2R/2R, 2R/3C, 2R/3G, 3G/3G,3C/3C and 3G/3C,their frequencies were 3. 6％, 19. 3％, 8.4％, 19. 3％, 37. 3％ and 12. 1％, respectively; ( 3 ) Of the 83 patients, the frequencies of the TS 3′-UTR ins6/ias6、ins6/del6 and del6/del6 were 8.4％ 、50.6％ and 41.0％, respectively; (4) TSER polymorphisms were correlated with lymph node metastasis ( P = 0.019 ),Ki67 ( P = 0.022 ) and histological grade ( P = 0.042 ). The TS 3′-UTR polymorphisms were correlated with age ( P = 0.002) and histological grade (P = 0.042). G→C SNP were correlated with lymph node metastasis ( P = 0.021 ) and histological grade ( P = 0.028 ).ConclusionsChinese female Han-nationality breast cancer patients have more genotypes frequencies of the TSER 3R/3R and 3′-UTR del6/del6; The TS polymorphisms are correlated with pathological factors of breast cancer.
