BACKGROUND:Clinical resection of thoracolumbar spinal tumor has a great impact on the spinal stability. Positive internal fixation is required clinicaly in order to maintain the spinal stability. The use of titanium mesh implantation can provide a firm internal fixation folowing resection of tumors. OBJECTIVE:To explore the spinal stability undergoing titanium mesh implantation with internal fixation folowing thoracolumbar tumor resection. METHODS:Twenty-four patients with thoracolumbar tumor admitted at the Central Hospital of Suining City from September 2013 to September 2014 were randomly selected and given tumor resection folowed by titanium mesh implantation with internal fixation. After treatment, patients were folowed up for 1-12 months to observe and analyze the neural functional recovery and spinal stability of the patients. RESULTS AND CONCLUSION:Al the 24 patients successfuly completed the operation treatment, and there was no case of death at the end of folow-up. During the folow-up, patient's clinical symptoms and neural function were significantly relieved, and Frankel classification was significantly improved after treatment. Regular X-ray examination showed that there was no change in the position of titanium mesh and anterior internal fixation system. There was also no titanium mesh colapse, internal fixation fracture and loosening, and the spinal stability was stil excelent. These findings indicate that patients were not changed, and did not appear because the amount of loose, good spinal stability. Resection of thoracolumbar tumors showed that the thoracolumbar spinal reconstruction with titanium mesh implantation combined with internal fixation folowing tumor resection can obtain good clinical effect and excelent biocompatiblity.

BACKGROUND: Experimental proof for the efficacy, safety, and immunological assessment is needed when minocycline is used for root canal disinfection.OBJECTIVE: To investigate the effect of minocycline for root canal disinfection on levels of interleukin-17 in apical exudates of periapical periodontitis and periapical exudate volume.METHODS: Sixteen patients with acute periapical periodontitis (16 teeth) scheduled for root canal therapy were enrolled and randomly divided into calcium hydroxide and minocycline groups, respectively, followed by root canal disinfection.One week after disinfection, periapical index, periapical exudate volume and interleukin-17 level were detected prior to the root canal filling. Another 16 patients with normal pulp vitality (16 teeth) scheduled for single root canal filling were enrolled as control group, in which periapical index, periapical exudate volume and interleukin-17 level were detected.RESULTS AND CONCLUSION: The periapical exudate volume and interleukin-17 level in the calcium hydroxide and minocycline groups were significantly higher than those in the control group (P < 0.05). The periapical index and interleukin-17 level in the calcium hydroxide and minocycline groups were decreased significantly at 1 week after root canal disinfection (P < 0.05), while there was no difference between these two experimental groups in the periapical index, periapical exudate volume and interleukin-17 level. To conclude, the use of minocycline significantly reduces interleukin-17 level and periapical exudate volume, and thus achieves effective outcomes in periapical disease.

Objective To study the effect of astragaloside on proliferation and apoptosis in human keloid fibroblasts.Methods The human keloid fibroblast ceils were treated with different concentration of astragaloside(10、20、40 ng/mL).Cell proliferation was detected by MTT,the gene expreesion levels and protein levels of apoptosis-related proteins,survivin,p53 and Bcl-2.were determined by real-time PCR and Western blot,respectively.Results Comparecl with control group(treated with 0 ng/mL astragaloside),the absorbance values (A490 nm) of each concentration group were significantly reduced,which suggest that the proliferation of all keloid fibroblast were markably inhibited in a dose-dependent way (P＜0.05).The gene expreesion levels and protein levels of apoptosis-related proteins,survivin、Bcl-2 were largely suppressed and P53 werelargely promoted in a dose-dependent.Conclusion The keloid fibroblasts cells proliferation and apoptosis could be regulated by astragaloside.

Objective To investigate the knowledge,attitude and behavior of medical staffs on foodborne diseases.Methods To investigate the knowledge,attitude and behavior of medical staffs on foodborne diseases by random sampling following the questionnaire.Results There were 332 medical workers attending the survey.The medical staffs were lack of knowledge for foodborne disease,percent of pass was 34.33％.The pass rate of attitude and behavior were 88.88％ and 98.19％.The knowledge score of medical staff of top three hospital (6.49± 2.18)were lower than the community health service center(7.04±2.26) (P＜0.05),but attitude and behavior score of this two staffs had not statistical differences(P＞0.05).Conclusion It is necessary to help medical staff to improve the attitude of foodborne diseases,and improve the monitoring of underreporting case.

Objective To explore expression of the minichromosome maintenance 2 (MCM2)protein and the mucin-like cell surface adhesion molecule CD24 in non-small cell lung cancer (NSCLC) and their relationship with its prognosis. Methods Seventy-three patients of NSCLC diagnosed for the first time and received surgical treatment in Xuanwu Hospital, Beijing were selected for the study. Expression of the MCM2 and CD24 in pathological specimens of the patients was measured by immunohistochemistry and their relationship with its prognosis was analyzed retrospectively. Results High-level expression of the MCM2 and CD24 was seen in 42 and 54 of 73 NSCLC patients, accounting for 57. 5 percent and 74. 0 percent,respectively. Risk of death for the patients with high-level expression of the MCM2 or the CD4 was significantly higher as compared to those with low-level expression ( P ＜ 0. 05 ). Risk of death for patients with both high-level expression of the MCM2 and CD24 was significantly higher than that in those with only high-level expression of the MCM2 or the CD24 (HR =2. 59, 95%CI 1.40 -4. 80, P=0. 002) and in those with both low-level expression of them ( HR = 15.32, 95 % CI = 2.07 - 113.41, P = 0. 008 ). But there was no significant difference in risk of death between patients with high-level expression of the MCM2 or CD24 and those with low-level expression of both of them ( HR = 5. 60, 95% CI 0. 79 - 44. 82, P = 0. 083 ), and cumulative survival rate of patients with both high-level expression of the MCM2 and CD24 was significantly lower than those with only high-level expression of the MCM2 or the CD24 ( P = 0. 001 ). Conclusions Both expression of the MCM2 and the CD24 are independent prognostic factors for NSCLC and combined detection of the two markers have higher prognostic value for it.

Objective To investigate the expression of MCM2 and its prognostic significance in non-small cell lung cancer (NSCLC). Methods The expression of MCM2 was measured by immunohistochemistry in 73 cases of NSCLC and 10 cases of normal lung tissue. The correlations between the expression of MCM2 and clinic-opathological parameters and prognosis were investigated. Results There was no MCM2 expression in normal lung tissue and positive rate of MCM2 expression was 87.7% in NSCLC. The difference between the two groups was significant (P<0.001). The expression of MCM2 in poorly differentiated NSCLC patients was significantly higher than that in moderately- and well-differentiated NSCLC patients (P=0.008). The expression of MCM2 in patients with squamous carcinoma was higher than that in patients with adenocarcinoma (P=0.005). The hazard ratio was significantly higher(RR=3.389, 95 % CI=1.803-7.146,P<0.001), and the accumulated survival rate was significantly lower (P=0.001) in NSCLC patients with higher MCM2 expression than that of lower expression. MCM2 was independent prognostic factor of NSCLC patients (P=0.041). Conclusion MCM2 could reflect the reproductive activity of NSCLC and has some clinical significance for assessing the development and prognosis of NSCLC. MCM2 was a potential target for future treatment.
