  • The Prevalence of Metabolic Syndrome and Correlation of Waist-to-hip Ratio and Body Mass Index with Metabolic Syndrome in Certain University

    Objective We aimed to describe the prevalence of metabolic syndrome, its epidemiological characteristics, and to analyse the relationship of waist-to-hip ratio (WHR) and body mass index (BMI) with metabolic syndrome (MS) among staff at Southeast University. Methods The data from the overall physical examination of 1979 staff were analyzed.Results The crude prevalence of MS were 21.7%,26.4% and 14.2% in the whole population, men and women respectively. The standardized rates were 14.7%,19.0% and 9.4%. The prevalence of MS in men was significantly higher than that in women(Plt;0.05). Both abdominal obesity and visceral obesity were positively correlated with the prevalence of MS(r=0.295, 0.248, P=0.000). Conclusion The prevalence of MS among staff of Southeast University has shown a significant increase in 2006. WHR and BMI are both correlated with the prevalence of MS.

  • EXPERIMENTAL AND CLINICAL RESEARCH ON REPAIR OF GROWTH PLATE INJURY

    Objective To sum up the experimental and clinical history as wellas latest development of repair of growth plate injury Methods Recent articles about repair of growth plate injury were extensively reviewed and major reparative methods were introduced, especially including tissue engineering research on growth plate.Results Repair of growth plate injury was a great difficulty inexperimental study and clinical treatment of pediatric orthopedics. Transplantation of free growth plate and cartilage were unfavorably used because of lack ofblood supplement. Although circulation problem was solved by transplantation ofvascularized growth plate, autografts of epiphyseal cartilage were involved in limitation of donor, and allografts of epiphyseal cartilage induced immunological reaction. Noncartilaginous tissue and material could only prevent formation of bony bridge in small defect of growth plate and lacked ability of regenerative repair. Transplantationof tissue engineered cartilage and chondrocytes might be a choice for repair ofgrowth plate injury Conclusion Owing to lack of safe and effective methods ofrepairing growth plate injury, research on chondrocyte and tissue engineered cartilage should be further done.

  • ADVANCE ON REPAIR OF GROWTH PLATE INJURY

    OBJECTIVE: To sum up the studying course and latter development of repair of injury of growth plate. METHODS: Recent original articles about repair of injury of growth plate were extensively reviewed, focused on the progresses in understanding repair of injury of growth plate and comparison of several major reparative methods. RESULTS: Repair of injury of growth plate is a great difficulty in experimental study and clinical treatment of pediatric orthopedics. Graft of free growth plate and cartilage were unfavorably used because of lack of blood supplement. Although graft of vascularized growth plate solved circulation problem, both two kinds of grafts were involved in limitation of donor and immunologic reaction. Non-cartilaginous tissue and material could only prevent formation of bony bridge in small defect of growth plate and lacked ability of regenerative repair. Transfer of tissue engineered cartilage might be the best choice for repair of injury of growth plate. CONCLUSION: Considering source of transplanted material, reparative effect and adverse reaction, repair of injury of growth plate with tissue engineered cartilage deserves further investigation.

    Objective To investigate change of bispectral index(BIS) and hemodynamic index during induction and orotracheal intubation of sevoflurane anesthesia. Methods This study was a prospective before-after study in the same patients. A total of 30 ASA physical status I and II adult patients without airway abnormalities were enrolled to receive inhalation induction of anesthesia with 8% sevoflurane. Mean arterial pressure(MAP),heart rate(HR) and BIS were recorded before anesthesia(T1),when patients loss of consciousness(T2), before intubation (T3),at 1 min(T4) and 3 min(T5) after intubation. Results BIS at T1-T5 were 96.8±1.7,70.4±8.8,39.2±8.4,43.6±12.9 and 41.6±9.3 respectively, the measurements at T2-T5 were all markedly lower than at T1(Plt;0.05). HR at T3-T5 were all markedly higher than at T1(Plt;0.05). MAP at T2 and T3 were markedly lower than at T1, but at T4 was higher than at T1(Plt;0.05), and recovered to the level at T1 at T5(Pgt;0.05).BIS,HR and MAP at T4 were all significantly higher than T3(Plt;0.05). Conclusion Anesthesia induction with sevoflurane and small dose of succinylchoiline we used can provide adequate depth of general anesthesia,but can not prevent cardiovascular adverse reactions to intubation.

  • Relationship Between Disease Severity and Life Quality in Patients with Chronic Obstructive Pulmonary Disease

    Objective To compare BODE index with GOLD staging for the severity evaluation in patients with chronic obstructive pulmonary disease ( COPD) . To investigate the relationship between BODE index and quality of life. Methods A total of 100 patients with stable COPD were enrolled. All participants were examined with lung function test and St George’s Respiratory Questionnaire ( SGRQ) for evaluation of quality of life. BODE index and it’s four components including body mass index( BMI) , airflow obstruction ( FEV1%pred) , dyspnea( MMRC) , and exercise capacity( 6MWD) were calculated. The participants were divided into four groups of severity using GOLD guidelines and BODE index quartiles. Results The associations between SGRQ total score and SGRQ subscales, and BODE index were significant( P lt;0. 01) .BODE index was a significant predictor of the quality of life, explaining 41. 3% of the total score of the SGRQ ( P lt;0. 01) . However, GOLD classification showed a correlation only with SGRQ activity score ( P lt;0. 05) but not with other SGRQ scores. There were significant differences in SGRQ total score and SGRQsubscales between different severity groups of BODE index( P lt;0. 01) . But there was no difference in SGRQ score between different severity groups of GOLD classification, except SGRQ activity score. Conclusion BODE scoring system is better correlated with the quality of life as assessed by the disease severity inpatients with COPD than the GOLD staging criteria.

  • Effects of Diesel Exhaust Particle on Expression of Eotaxin in Asthmatic Rats

    Objective To investigate the effects of diesel exhaust particles ( DEP) on the production of CCL11, CCL24 and CCL26 in asthmatic rats. Methods Fifty SD rats were randomly divided into five groups. Group A was an normal control group. The rats in group B, C, D, and E were sensitized and challenged by ovalbumin ( OVA) to establish asthma model. Then the rats in the group C, D, E were inhaled DEP for 1, 2, 3 weeks, respectively. Lung tissue and brouchoalveolar lavage fluid ( BALF) were collected for detection of CCL11, CCL24, and CCL26 expression by ELISA and q-RT-PCR. Results The transcription of CCL 24, CCL26 gene and the production of CCL24 and CCL26 protein increased significantly compared with the control group ( P lt;0. 05) , and were positively associated with the DEP inhalation time. However, CCL11 gene and protein expression were not changed significantly compared with the control. Conclusion The exposure to DEP can induce the production of CCL24 and CCL26 in the asthmaic rats, which might aggravateairway hyperresponsiveness.

  • EFFECT OF RIVAROXABAN ON RISK OF BLEEDING AFTER TOTAL KNEE ARTHROPLASTY

    Objective To investigate the effect of rivaroxaban on the risk of bleeding after total knee arthroplasty (TKA). Methods A total of 119 cases undergoing primary TKA because of knee osteoarthritis between June 2009 and May 2011, were randomly divided into the rivaroxaban group (59 cases) and the control group (60 cases). There was no significant difference in gender, age, height, weight, side, disease duration, and grade of osteoarthritis between 2 groups (P gt; 0.05). Thepreoperative preparation and operative procedure of 2 groups were concordant. At 1-14 days after TKA, rivaroxaban 10 mg/d were taken orally in the rivaroxaban group, and placebo were given in the control group. The blood routine examination was performed before operation and at 2 days postoperatively; the total blood loss and hemoglobin (HGB) decrease were calculated according to the formula; the blood loss, postoperative wound drainage, and wound exudate after extubation were recorded to calculate the dominant amount of blood loss; and the bleeding events were recorded within 35 days postoperatively. Results The total blood loss and HGB decrease were (1 198.34 ± 222.06) mL and (33.29 ± 4.99) g/L in the rivaroxaban group and were (1 124.43 ± 261.01) mL and (31.57 ± 6.17) g/L in the control group, showing no significant difference (P gt; 0.05); the postoperative dominant blood loss in the rivaroxaban group [(456.22 ± 133.12) mL] was significantly higher than that in the control group [(354.53 ± 96.71) mL] (t=4.773, P=0.000). The bleeding events occurred in 3 cases (5.1%) of the rivaroxaban group and in 1 case (1.7%) of the control group, showing no significant difference (χ2=1.070, P=0.301). Conclusion Rivaroxaban has some effects on the risk of bleeding after TKA. In general, rivaroxaban is safe.

    Objective To improve the safety of the percutaneous anterior transarticular screw fixation (PATSF) by measuring the parameters related to PATSF. Methods Spiral CT scan and three-dimensional reconstructions of the atlantoaxis were performed in 50 adult volunteers. The section of inner margin of atlantal superior articular facet, the coronal plane ofvertebral artery cavity, and the sagittal plane of atlano-axis were obtained with multiplanar reconstruction on hel ical CT. The atlantoaxial vertebral structure and the direction of vertebral artery cavity were observed. The parameters related to PATSF were measured and analysed. Results The suitable position of screw insertion was 4.0 mm from the midpoint of the axoidean anteroinferior margin. The maximum external angle of PATSF was (29.89 ± 1.41)°; the minimum external angle was (4.37±0.87)°; the maximum backward angle was (32.41 ± 1.66)°; the optimal external angle was (17.13 ± 0.88)°; the optimal backward angle was (17.62 ± 1.03)°; and the optimal screw length was (41.57±0.79) mm. The atlantoaxial articular facial diameter was (16.71 ± 1.61) mm; the maximum distance of atlantal lateral displacement was (6.96 ± 1.09) mm; and the ratio of them was 41.80% ± 5.69%. Conclusion The optimal insertion of PATSF is safe and rel iable. The screw can be inserted when the displacement of the atlantal lateral mass is in a certain degree.

  • BMSCs -CHITOSAN HYDROGEL COMPLEX TRANSPLANTATION FOR TREATING INTERVERTEBRAL DISC DEGENERATION

    Objective To investigate the therapeutic effect of BMSCs- chitosan hydrogel complex transplantation on intervertebral disc degeneration and to provide experimental basis for its cl inical appl ication. Methods Two mill il iter of bone marrow from 6 healthy one-month-old New Zealand rabbits were selected to isolate and culture BMSCs. Then, BMSCs at passage 3 were labeled by 5-BrdU and mixed with chitosan hydrogel to prepare BMSCs- chitosan hydrogel complex. Six rabbitswere selected to establ ish the model of intervertebral disc degeneration and randomized into 3 groups (n=2 per group): control group in which intervertebral disc was separated and exposed but without further processing; transplantation group in which 30 μL of autogenous BMSCs- chitosan hydrogel complex was injected into the center of defected intervertebral disc; degeneration group in which only 30 μL of 0.01 mol/L PBS solution was injected. Animals were killed 4 weeks later and the repaired discs were obtained. Then cell 5-BrdU label ing detection, HE staining, aggrecan safranin O staining, Col II immunohistochemical staining and gray value detection were conducted. Results Cell label ing detection showed that autogenous BMSCs survived and prol iferated after transplantation, forming cell clone. HE staining showed that in the control and transplantation groups, the intervertebral disc had a clear structure, a distinct boundary between the central nucleus pulposus and the outer anulus fibrosus, and the obviously stained cell nuclear and cytochylema; while the intervertebral disc in the degeneration group had a deranged structure and an indistinct division between the nucleus pulposus and the outer anulus fibrosus. Aggrecan safarine O stainning notified that intervertebral disc in the control and transplantation groups were stained obviously, with a clear structure; while the intervertebral disc in the degeneration group demonstrated a deranged structure with an indistinct division between the nucleus pulposus and the anulus fibrosus. Col II immunohistochemical staining showed that the tawny-stained region in the control group was located primarily in the central nucleus pulposus with a clear structure of intervertebral disc, the central nucleus pulposus in the transplantation group was positive with obvious tawny-stained intercellular substances and a complete gross structure, while the stained color in the degeneration group was l ighter than that of other two groups, with a indistinct structure.Gray value assay of Col II immunohistochemical staining section showed that the gray value of the control, the ransplantation and the degeneration group was 223.84 ± 3.93, 221.03 ± 3.53 and 172.50 ± 3.13, respectively, indicating there was no significant difference between the control and the transplantation group (P gt; 0.05), but a significant difference between the control and transplantation groups and the degeneration group (P lt; 0.05). Conclusion The rabbit BMSCs-chitosan hydrogel complex can repair intervertebral disc degeneration, providing an experimental foundation for the cl inical appl ication of injectable tissue engineered nucleus pulposus complex to treat intervertebral disc degeneration.
