Objective To compare the clinical outcomes of Bryan disc replacement with anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylopathy. Methods Sixteen patients underwent Bryan cervical disc replacement (A group), and 35 patients underwent traditional ACDF (B group) were included in the study. Patients were followed up at regular intervals. The JOA score, SF-36, neck disability index (NDI) score and the dynamic flexion-extension radiographs were used to evaluated the oucomes.Results All the patients were followed up for more than 6 years (mean, 73.5 months). There were no severe adverse events in both groups. In A group, there were no differences between postoperative and preoperative mobility of surgical segments (P＞0.05). All patients obtained bone fusions 6 month after surgery in group B.In both groups, the clinical symptoms relieved obviously after surgery. The postoperative scores of the JOA,SF-36 and NDI significantly improved compared with those of preoperative ones (P＜0.05). In B group, range of motion (ROM) was significantly decreased postoperatively (P ＜0.01); in A group, there were no significant differences between postoperative and preoperative ROM (P＞0.05). The difference between two groups regarding ROM was noted (P＜0.05). Conclusion The mid-term outcomes of Bryan cervical arthroplasty are satisfied. And the cervical arthroplasty which can maintain the mobility of the segment, and decrease the incidence of the postoperative neck axial symptoms is a viable alternative to cervical spondylopathy.

Objective To assess the effects of fenofibrate on myocardial remodeling in obese rats by echocardiography.Methods Twenty-six SD rats were fed with high fat chow to establish twenty obese rats models,which were randomly divided into two groups:obesity group (OB group,n =10) and fenofibrate group(F group,n =10).The same week-old SD rats group (n =10) was also randomly selected as normal control group.F group was given fenofibrate 60 mg · kg-1 · d-1 for 8 weeks,the other groups were given normal saline.Echocardiographic scan was performed in each group at the beginning and ending of the experiment.Twenty-four weeks later,all rats were executed and the cardiac muscle was used to histological inspect.Results After the experiment,compared with the control group,the body weight,the ventricular thickness,interventricular septal thickness and the left ventricular mass in OB group were significantly increased than those of control group(P ＜0.01),the E/A ratio was significantly decreased(P ＜0.01).Histological detection showed that myocardial structure was disordered,and that interstitial collagen was deposited in the myocardium.Compared with OB group,the parameters all above in F group were significantly improved (P ＜0.01).Left ventricular mass from echocardiography correlated well with the results from pathologic specimen (r =0.98,P ＜0.01).Conclusions Fenofibrate has beneficial effects on preventing myocardial remodeling.By general echocardiography,the effects can be assessed comprehensively and accurately.

Objective To evaluate biomechanical effect of bone cement distribution on lumbar vertebral body with osteoporotic fracture.Methods Forty nine lumbar vertebrae (L1-L5) specimens were collected from 12 old cadavers.After exerting axial pressure load on every specimen,the initial intensity and stiffness were measured,and then vertebral body crush fracture models were established.According to zones where bone cement was injected in vertebrae,the specimens were divided into one control group and six experimental groups:A,B,C,D,E,F groups,i.e.unilateral anterior 2/3 group,unilateral posterior 2/3 group,unilateral whole group,bilateral anterior 2/3 group,bilateral posterior 2/3 group,and bilateral whole group,respectively,including 7 specimens in each group.In A,B,C groups,unipedicular balloon kyphoplasty was done,while in D,E,F groups,bipedicular balloon kyphoplasty was done.Then the maximum compressive strength and stiffness were measured.Results After percutaneous kyphoplasty,the maximum strength in all experimental groups was significantly greater than that in the control group.There were no significant differences in strength between A and B groups,between C,D and E groups.For the maximum strength,the results of comparison were:F group ＞ C group,D and C groups ＞ A and B groups.Except for F group,the stiffness in other 5 experimental groups was significantly lower than its initial value.There were no significant differences in stiffness between A,B,and C groups,between D and E groups.However,the stiffness in F group was greater than those in D and E groups,and it was greater in bilateral groups than those in unilateral groups.Conclusion Bone cement distribution in lumbar vertebral body can affect biomechanical property of vertebral body,and the bilateral distribution can cause better biomechanical effect than unilateral distribution.The ideal distribution zone of bone cement is in the anterior 2/3 of the vertebral body.

Background Drug resistance is the main cause of failure after chemotherapy of retinoblastoma (RB),and how to improve the sensitivity of RB cells to chemotherapic drug become an urgent issue.All trans retinoic acid (ATRA) can inhibit the growth of tumor cells.However,whether ATRA increases the sensitivity of RB cells to chemotherapic drug is unclear.Objective This study aimed to investigate the inhibitory effect of ATRA with vincristine on the proliferation of SO-RB50 cells.Methods SO-RB50 cells were cultured routinely.Different concentrations of ATRA or vincristine were added into the medium for 48 hours for the determination of IC50 by cell counting kit-8 (CCK-8) method.Cultured cells were divided into normal control group,ATRA group,vincristine group and combined drug group.The cells were treated by ATRA or vincristine with the dose of IC50,and the proliferation of the cells was detected every day at the 24-hour interval for 6 consecutive days.The percentage of the cells in different cell cycles was analyzed 72 hours after treatment using flow cytometry.Cell apoptosis rate was detected and calculated 48 hours after treatment by annexin V/propidium iodide (PI) method.Results The IC50 of ATRA was approximately 12.84 μ mol/L,and that of vincristine was 0.11 μg/ml.The growth curve of SO-RB50 cells was gradually raised as the lapse of time,but the curves were relatively low in the ATRA group,vincristine group and combined drug group,with the lowest curve in the combined drug group.The proliferation values of the cells (A450)were 1.078±0.022,0.611 ±0.038,0.596 ±0.031 and 0.483 ±0.030 in 48 hours after treatment,and those in 72 hours were 1.380± 0.021,0.799 ± 0.016,0.668 ± 0.041 and 0.532 ± 0.033 in normal control group,ATRA group,vincristine group and combined drug group,showing significant differences among the groups and various time points (Fgroup =1115.207,P =0.000;Ftime =257.781,P =0.000).The A450 values of the ATRA group,vincristine group and combined drug group were significantly lower than those of normal control group (all at P＜0.05).The percentage of the cells in different cell cycles was changed after 72 hours' treatment and the differences were statistically significant (FG0/G1 =130.565,Fs =57.435;FG2/M =114.290,P＜0.05).Compared with the normal control group,the percentage of G0/G1 phase cells was increased and S phase cells was decreased significantly in ATRA group,the percentage of G0/G1 phase cells was decreased and G2/M phase cells was increased significantly in vincristine group(P＜0.05).The apoptotic rate of the cells was (7.17±0.18) ％,(27.34±1.36) ％,(27.49±2.45) ％ and (34.50±1.84) ％ in normal control group,ATRA group,vincristine group and combined drug group,with a significant difference among the groups (F=147.555,P＜0.05),and the apoptotic rate in the combined drug group was remarkedly lower than that of normal control group,ATRA group and vincristine group (all at P=0.000).Conclusions ATRA can improve the sensitivity of SO-RB50 cells to chemotherapeutic drug.The combined application of ATRA and vincristine enhance the inhibitory effect on the cells probably by regulating cell cycle and inducing apoptosis.

Objective To determine the efficacy of berberine in the treatment of non-alcoholic steatohepatitis ( NASH) , and to investigate the regulating effect on macrophage phenotype transformation in hepatic tissue on methionine -choline deficiency (MCD) diet induced NASH mice.Methods Fourty male C57BL/6 mice were randomly divided into 4 groups (10 mice per group): the normal group (fed with normal diet), the NASH model group (fed with MCD diet), rosiglitazone treatment group (30mg/kg) and berberine treatment group (150mg/kg).Drugs were adopted in the preventive intervention method for 2 weeks.The hepatic histopathological method was adopted to evaluate the drug therapeutic effect.The serum levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, and IL-10 were examined with ELISA method.M1 and M2 phenotype were detected by flow cytometry .Results The results showed berberine improved the degree of hepatic histopathology .Berberine not only reduced the level of TNF-α, but also increased the level of IL-10 in serum on NASH mice significantly ( P <0.05 ) . Flow cytometry data indicated that berberine decreased M 1 type macrophages and increased M 2 type macrophages in liver tissue .The ratio of M1/M2 was significantly decreased in berberine and rosiglitazone treated group ( P <0.01 ) .Conclusion Berberine may improve the hepatic pathological process in MCD diet induced NASH model possibly through modulating macrophage phenotype transformation , i.e.The ratio of M2 type is more than M1 type in hepatic tissue , and increasing anti-inflammatory cytokines .

Results: In comparison of the values in amplitude of low-frequency fluctuation (fALFF) during and before moxibustion, it has been found that in moxibustion of 2 cm distance, fALFF value increased in the brain regions of the left anterior cingulated cortex and lateral surrounding cerebral regions, and fALFF value decreased in the cerebral regions of the peripheral cortex of the calcarine fissure; in moxibustion of 3 cm distance, fALFF value increased in the brain regions of the right and medial side and paracingulated gyrus, and fALFF value decreased in the cerebral zone of the left middle temporal gyrus; in moxibustion of 4 cm distance, fALFF value increased in the brain regions of the right and medial and paracingulated gyrus; and in moxibustion of 5 cm distance, fALFF value increased in the brain regions of the left hippocampus. In comparison of the value of regional homogeneity (ReHo), it has been found that in moxibustion of 2 cm distance, ReHo value increased in the cerebral zone of the posterior lobe of the right cerebellum, and ReHo value decreased in the cerebral zone of the right occipital lobe; in moxibustion of 3 cm distance, ReHo value increased in the brain regions of the left cerebellar posterior lobe and left frontal lobe, and ReHo value decreased in the cerebral zone of the right inferior temporal gyrus; in moxibustion of 4 cm distance, ReHo value increased in the brain regions of the right superior frontal gyrus and ReHo value decreased in the brain regions of the right parietal lobe and angular gyrus; in moxibustion of 5 cm distance, ReHo value increased in the cerebral zone of the right frontal lobe and ReHo value decreased in the cerebral zone of the right brainstem. Conclusion: In moxibustion of 3 cm distance, the changes in the brain regions basically conform to the transmission route of body trunk temperature.

Background: Disruption of tight junctions between intestinal epithelial cells followed by loss of barrier function is crucial for the pathogenesis and progression of a variety of gastrointestinal disorders.Aims: To investigate the protective effect of ulinastatin on hydrogen peroxide (H2O2)-induced intestinal epithelial barrier disruption.Methods: Model of intestinal epithelial monolayer barrier was established with Caco-2 cells in vitro,and then divided into four groups: blank control group (without any intervention),H2O2 group (500 μmol/L H2O2),low-dose (500 U/mL) and high-dose (3 000 U/mL) ulinastatin groups (ulinastatin + H2O2).Level of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) were detected;transepithelial electrical resistance (TEER) and flux of sodium fluorescein were measured to assess the barrier function;expression and localization of two tight junction proteins,ZO-1 and occludin were evaluated by Western blotting and immunofluorescence;ultrastructure of tight junctions was observed by transmission electron microscopy (TEM).Results: Compared with the blank control group,treatment of Caco-2 cell monolayers with H2O2 resulted in increase in level of MDA,flux of sodium fluorescein and decrease in activity of SOD,TEER and expressions of ZO-1 and occludin (P all ＜0.05).TEM and immunofluorescence showed that the brusher border of Caco-2 cells in H2O2 group was destroyed,the cell-cell junction was vague and the localization of ZO-1 and occludin was discontinuous and the fluorescence intensity was extremely low.While in ulinastatin groups,especially the high-dose group,all the indices above-mentioned were significantly improved (P all ＜0.05).Conclusions: Ulinastatin protects intestinal epithelial monolayer barrier against H2O2-induced disruption at least partially by its antioxidant activity and modulating expression and localization of tight junction proteins.
