OBJECTIVE@#To investigate the clinical efficacy of posterior cervical pedicle screw short-segment internal fixation for the treatment of atlantoaxial fracture and dislocation.@*METHODS@#The clinical data of 60 patients with atlantoaxial vertebral fracture and dislocation underwent surgery between January 2015 and January 2018 were retrospectively analyzed. The patients were divided into study group and control group according to different surgical methods. There were 30 patients in study group, including 13 males and 17 females, with an average age of (39.32±2.85) years old, were underwent short-segment internal fixation with posterior cervical pedicle screws. There were 30 patients in control group, including 12 males and 18 females, with an average age of (39.57±2.90) years old, were underwent posterior lamina clip internal fixation of the atlas. The operation time, intraoperative blood loss, postoperative ambulation time, hospitalization time and complications between two groups were recorded and compared. The pain visual analogue scale(VAS), Japanese Orthopedic Association(JOA) score of neurological function, and fusion status were evaluated between two groups.@*RESULTS@#All patients were followed up for at least 12 months. The study group was better than control group in operation time, intraoperative blood loss, postoperative off-bed activity time, and hospital stay (P=0.000). One case of respiratory tract injury occurred in study group. In control group, 2 cases occurred incision infection, 3 cases occurred respiratory tract injury, and 3 cases occurred adjacent segmental joint degeneration. The incidence of complications in study group was lower than that in control group (χ2=4.705, P=0.030). At 1, 3, 7 days after operation, VAS of study group was lower than that of control group(P=0.000). At 1, 3 months after operation, JOA score of study group was higher than that of control group(P=0.000). At 12 months after operation, all the patients in the study group achieved bony fusion. In control group, there were 3 cases of poor bony fusion and 3 cases of internal fixation fracture, the incidence rate was 20.00%(6/30). The difference between two groups was statistically significant (χ2=4.629, P=0.031).@*CONCLUSION@#Posterior cervical short-segment pedicle screw fixation for atlantoaxial fracture and dislocation has the advantages of less trauma, shorter operation time, fewer complications, and less pain, and can promote the recovery of nerve function as soon as possible.

Effect of MCUR1 on proliferation,cell cycle and apoptosis of K562 cells / 军事医学

Objective To investigate the effect of mitochondrial calcium uniporter(MCU)regulator 1(MCUR1)on proliferation,cell cycle and apoptosis of K562 cells and the possible molecular mechanism.Methods Recombinant plasmid vectors containing short hairpin RNAs(shRNAs)targeting MCUR1 were transfected into K562 cells,before the K562 cells stably expressing low MCUR1 were selected with G418.The expression of MCUR1 mRNA was detected by quantitative real-time polymerase chain reaction(qRT-PCR)assays.Western blotting(WB)assays were used to detect the expressions of MCUR1,P53,BAX and BCL2.The proliferation,cell cycle and apoptosis of K562 cells were detected by cell counting kit-8(CCK-8)assays and flow cytometry, respectively.Results The results of qRT-PCR and WB assays revealed that MCUR1 was stably down-regulated at mRNA and protein levels in the K562 cells transfected with shRNAs targeting MCUR1.Knockdown of MCUR1 significantly inhibited the cell proliferation, induced the cell apoptosis, but did not influence the cells cycle.Meanwhile, knockdown of MCUR1 increased the expression of P53 protein and the ratio of protein BAX/BCL2 in K562 cells.Conclusion MCUR1 promotes cell proliferation and inhibits cell apoptosis in K 562 cells.

Effects of electroacupuncture at "Fenglong" (ST 40) on formation of macrophage-derived foam cell and efflux of cholesterol in hyperlipidemia rats / 中国针灸

<p><b>OBJECTIVE</b>To explore action mechanism of electroacupuncture (EA) at "Fenglong" (ST 40) for treatment of hyperlipidemia.</p><p><b>METHODS</b>Forty SPF-grade SD rats were randomly divided into a normal group (group A), a model group (group B), a model diet-control group (group C), a model + EA group (group D) and model diet-control + EA group (group E), 8 cases in each one. The rats in group A were fed with normal diet continuously while those in the rest 4 groups were fed with high-fat diet to establish hyperlipidemia model. Afterwards, the rats in group C and group E were fed with normal diet, while EA at "Fenglong" (ST 40) was applied in group D and group E, 30 min per time, once a day. After 28 days of treatment, macrophage was collected in each group. Oil red O-staining was applied to detect the formation of foam cells, and enzyme-linked immunosorbent assay (ELISE) was adopted to measure the contents of total cholesterol (TC) in macrophage and analyze the rate of cholesterol efflux.</p><p><b>RESULTS</b>The counts of positive cells of oil red O-staining and the contents of TC in the group B, group C and group D were significantly increased compared with those in the group A (all P < 0.01). The counts of positive cells and contents of TC in the group C, group D and group E were significantly clecreased compared with those in the group B (all P < 0.01), and the decline in group D was more obvious than that in the group C (all P < 0.01). Compared with group C and group D, the counts of positive cells and contents of TC in the group E was obviously decreased (all P < 0.01), which was not statistically different from group A (P > 0.05). In the meantime, compared with group C, the rate of cholesterol efflux in group D and group E was significantly increased (both P < 0.01), and the rise in group E was more obvious than that in the group D.</p><p><b>CONCLUSION</b>The electroacupuncture at "Fenglong" (ST 40) could significantly prohibit the transformation of macrophage into foam cell and increase rate of cholesterol efflux in macrophage, which could prevent and reverse the formation of foam cell and play an essential role in treating hyperlipidemia and stopping it from developing into a further level.</p>

Gene sequence analysis and prokaryotic expression of sigmaB protein of Muscovy duck reovirus YB strain / 病毒学报

Muscovy ducks reovirus (DRV) is an important pathogen with a high mortality rate in Muscovy ducks, the researches in the test and the immunity were useful for the prevention and control of DRV infection. In this study, the S3 genes of the three Fujian DRVs were cloned by RT-PCR and sequencing technology. It was found that DRV-YH and YJL were close to avian reovirus (ARV) in the genetic distance, with high identities ranged from 94. 6% to 98. 9%, however, the identities of DRV-YB strain and reference ARV strains in the S3 gene were only 60.6% - 61.7%. The expression vector pET-30a-S3 harboring DRV YB strain S3 gene was constructed and transformed into E. coli BL21, and then the fusion sigmaB protein expression was induced with IPTG. The SDS-PAGE of the expressed products indicated that the fusion protein of approximately 42ku in molecular weight was expressed highly in inclusion body, and made up 67. 7% of the total proteins. The most efficient concentration of IPTG and inducing time were 0. 1 mM and 5h respectively, while the best temperature for expression was 37 degrees C. After purification with the Ni2+ affinity chromatography, the fusion sigmaB protein was 93% of the total proteins, and the purified protein amounted to 0. 86g/L. The Western blot analysis showed that the fusion aB protein was recognized specifically by the antiserum against DRV, confirming that the recombinant fusion protein had good immunoreactivity.
