It also proposed four aspects of adjustment through strengthen the significance, thesis defense, defense supervision content development process and the detalled reply results to perfect defense system.

BACKGROUND: In vivo and in vitro experiments have demonstrated that polyetheretherketone (PEEK) polymer is the best cervical fusion cage material due to its good biocompatibility, elastic modulus similar to human bone, and satisfactory plasticity and hardness.OBJECTIVE: To assess the outcomes of polyetheretherketone (PEEK) cage filled with nano-artificial bone following anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylotic myelopathy.METHODS: In total 17 patients with cervical spondylotic myelopathy were collected from the Department of Orthopedics, First Affiliated Hospital of Harbin Medical University between May 2007 and September 2009. There were 12 males and 5 females,averaging 55 (range 42-67) years of age. All patients underwent ACDF using PEEK cage filled with nano-artificial bone. Patients'neurological functions were assessed on the basis of Japanese Orthopaedic Association (JOA) scoring system. The distance between the midpoint of the upper end plate and lower end plate was measured as interboby height. Radiographs with the neck in lateral flexion and extension were obtained to evaluate fusion results.RESULTS AND CONCLUSIONS: Seventeen patients with cervical spondylotic myelopathy participated in the final analysis.Almost all patients had symptomatic improvement. Within postoperative several days, muscle strength of lower limb was increased, and limb was more flexible after surgery than prior to surgery. At 3 months after surgery, JOA scores were significantly increased compared to prior to surgery, the operated segments were stable and disc space height was satisfactory. In addition, no complications were found, and all cases achieved solid fusion, as confirmed by radiographs. These findings suggest that the immediate stability of the operated segments can be obtained by anchoring PEEK cage, and the nano-artificial bone-filled PEEK cage is safe, simple, and with relatively few complications. It is therefore a good choice for patients with cervical spondylotic myelopathy.

Aim To investigate the protective effect of compound total flavonoids on atherosclerosis in ApoE -/- knockout mice.Methods Seven-week old C57BL/6 mice considered of the normal group (n =1 5 );seven-week old ApoE -/- mice were fed with high-fat diet and were assigned randomly into 5 groups:model group,simvastatin group,the low com-pound flavonoids group,the middle compound fla-vonoids group and the high compound flavonoids group.After 1 6 weeks,mice serum and aortas were harvested.The formation of atherosclerotic plaque was analyzed by HE staining,The serum level of lipids pro-files and superoxide dismutase (SOD )were deter-rnined.The levels of IL-1 βand NF-κB in serum were detected by ELISA assay.Results Area of atheroscle-rotic lesion was significantly less in the compound fla-vones group than in model.The level of TC,TG,LDL-C,IL-1 β,NF-κB in serum of the compound flavonoids group were decreased significantly,while SOD and HDL-C increased significantly compared with the mod-el group,and the difference was significant (P <0.05).Conclusion The compound flavonoids have a good protective effect on early atherosclerosis in mice, which may be due to its alleviating effects on hyperlipi-demia and inflammation and oxidation.

Objective To explore the pathway relationship among self consistency and congruence,life events and mental health,and to supply dependable data to psychotherapy and counseling about pilots.Methods Altogether 428 air force pilots were evaluated in air force Hangzhou sanatorium using self consistency and congruence scale (SCCS),life events scale(LES)and symptom checklist 90 (SCL-90).Spearman correlation analysis, one-sample t-test analysis and pathway analysis were used by soft package for social science version 15.0(SPSS 15.0)and AMOSv7.0.Results The results showed that there were significant relationships between all factors of self consistency and congruence and some factors of stressful life events(r=0.134～0.445);there were significant relationships between all factors of self consisteney and congruence and all factors of SCL-90(r=0.110～0.446); and negative life events of family,negative life events of work and negative life events of social communication were all had highly significant relationships with all factors of SCL-90(r=0.248～0.628).The pathway coefficient between life event and mental health Was B=0.39,P<0.01.The pathway coefficient among self consistency and congruence, life event and mental health were B=0.38,B=0.35,P<0.01,and the total adjust effects was 13.3%.Conclusion Self consistency and congruence is a important adjust variable between life events and mental health, can lighten the impact between life events and mental health.

0.05). In the anatomic plate group,2 cases developed loose of internal fixation,1 case of nail withdraw,without breakage,1 case of knee joint stiffness,1 case of traumatic arthritis in the knee joint. In the limited invasive stabilization system group,1 case affected traumatic arthritis in the knee joint. CONCLUSION:The therapeutic effects of anatomic plate and limited invasive stabilization system were similar in the treatment of complex tibial plateau fractures. Fixation materials should be selected according to the state of injury,bone conditions and economic status.

Objective To investigate the effects ofamiodarone (AMD) on simvastatin (SV) in human liver microsomes and the possible underlying mechanisms. Methods Time-, NADPH- and concentration-dependent inhibitions were tested in HLM. The logarithm of relative inhibition values was plotted versus preincubation time (0, 5, 10, 15, 20min) for a series concentration of AMD used (0, 2, 5,25, 50 μ mol/L), and the slopes determined by linear regression. These slope values represente the observed inactivation rate constants (kobs). A double-reciprocal plot was then constructed using the reciprocal of the ko～ (y-axis) and the reciprocal of the associated inhibitor concentration (x-axis) to estimate the values ofkinact and K, which were two principal kinetic constants that were specific for mechanism-based inhibition (MBI).drug-drug interactions (DDI) potential was predicted based on in vitro data and by using the in vitro-in vivo extrapolation. Results The time-, concentration- and NADPH-dependent charactga'istics confirmed that when SV was the substrate of CYP3A4, the inhibition of AMD to CYP3A4 is MBI. Kj and kinact value were calculated to be 5.1 μ mol/L and 0.018min-1 The Clint of SV was reduced 2.96-5.63 fold when it was administrated with AMD. Conclusion Based on the results, AMD would inhibit SV metabolism via the mechanism-based manner, which would lead to DDI when they are taken together. Careful clinical observation is recommended when AMD and SV have to be simultaneously prescribed.

OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.

METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.

RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).

CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.

OBJECTIVETo explore the effect of qidong huoxue decoction (QHD) on inflammatory factors and Toll-like receptor (TLR4) mRNA expressions in acute lung injury (ALI) rats.

METHODSTotally 50 healthy male SD rats were randomly divided into the blank control group, the lipopolysaccharide (LPS) model group, low, middle, high dose QHD groups according to body weight, 10 rats in each group. Rats in low, middle, high dose QHD groups were intragastrically administered with QHD at 4, 8, and 16 mL/kg 24, 12 h before modeling and 12 h after modeling, respectively. Normal saline was intragastrically administered to rats in the blank control group and the LPS model group. An ALI rat model was established using intratracheal instillation of LPS. Rats were killed after 24-h modeling. Then the bronchoalveolar lavage fluid was prepared. Contents of TNF-α, IL-1β, and L-10 were detected using ELISA. TLR4 mRNA expressions were determined byreal time PCR.

RESULTSCompared with the blank control group, contents of TNF-α, IL-1β , and IL-10 increased (P <0. 01), TLR4 mRNA expressions also increased in the LPS model group (all P <0. 01). Compared with the LPS model group, contents of TNF-α and IL-1β decreased (P <0. 05, P <0. 01), IL-10 levels increased (P <0. 01) , TLR4 mRNA expressions were also reduced (P <0. 01), in high and middle dose QHD groups. Compared with the high dose QHD group, con- tents of TNF-α and IL-1β increased in middle and low dose QHD groups (P <0. 05); IL-10 levels decreased (P <0. 05) in the low dose QHD group(P <0. 05), TLR4 mRNA expressions also increased in the low dose QHD group (P <0. 05). Compared with the middle dose QHD group, IL-10 levels was reduced, but TLR4 mRNA expressions increased in the low dose QHD group (P <0. 05).

CONCLUSIONSQHD had the protective effect on LPS induced ALI rats. Its mechanism might be associated with inhibiting TLR4 mRNA expressions, leading to decreased pro-inflammatory cytokines such as TNF-α and IL-β, elevated anti-inflammatory cytokine IL-10, and thereby, correcting unbalanced inflammation.
