Objective:To observe the effect of sodium fluoride (NaF) on the expression of phosphatidylinositol-3-kinase/protein kinase B (PI3K/Akt) signal and apoptosis in human osteosarcoma Saos-2 cells.Methods:Saos-2 cells were divided into 0 (control), 5, 10, 20 and 40 mg/L fluoride groups ( n= 3) according to the dose of NaF. The cells were collected after 24 and 48 h of culture in vitro. Western blotting was used to detect the expressions of PI3K/Akt signal and Forkhead transcription factor (FoxO) 1, and the apoptosis level of Saos-2 cells was detected by flow cytometry. Results:There were no significants differences in the expressions of PI3K and Akt in Saos-2 cells at 24 and 48 h ( P > 0.05). At 24 h, the expressions of phosphorylated PI3K (p-PI3K) in 5, 10, 20 and 40 mg/L fluoride groups (0.40 ± 0.06, 0.45 ± 0.02, 0.37 ± 0.06, 0.32 ± 0.06) were higher than that in the control group (0.28 ± 0.04, P < 0.05); at 48 h, the expressions of p-PI3K in 5 and 10 mg/L fluoride groups (0.46 ± 0.06, 0.58 ± 0.03) were higher than that in the control group (0.29 ± 0.04, P < 0.05), and that in the 40 mg/L fluoride group (0.21 ± 0.03) was lower than that in the control group ( P < 0.05). At 24 h, the expressions of phosphorylated Akt (p-Akt) in 5, 10 and 20 mg/L fluoride groups (0.27 ± 0.01, 0.30 ± 0.03, 0.27 ± 0.03) were higher than that in the control group (0.20 ± 0.02, P < 0.05); at 48 h, the expressions of p-Akt in 5 and 10 mg/L fluoride groups (0.42 ± 0.04, 0.60 ± 0.02) were higher than that in the control group (0.27 ± 0.01, P < 0.05), and that in the 40 mg/L fluoride group (0.18 ± 0.02) was lower than that in the control group ( P < 0.05). The expressions of FoxO1 in 10, 20 and 40 mg/L fluoride groups at 24 h (0.38 ± 0.07, 0.41 ± 0.06, 0.47 ± 0.08) were higher than that in the control group (0.34 ± 0.04, P < 0.05). At 48 h, the expressions of FoxO1 in 5, 10, 20 and 40 mg/L fluoride groups (0.36 ± 0.08, 0.37 ± 0.10, 0.54 ± 0.04, 0.73 ± 0.04) were higher than that in the control group (0.28 ± 0.04, P < 0.05).

ObjectiveTo investigate the clinical effects of posterior atlantoaxial fusion fixation in treatment of old atlantoaxial injury secondary to atlantoaxial dislocation.MethodsA retrospective analysis was carried out on 16 patients ( 14 males and 2 females) with old atlantoaxial injuries secondary to atlantoaxial dislocations managed with posterior atlantoaxial fusion fixation from March 2008 to March 2012.The time from injury to operation lasted for 3-36 months ( average 10.5 months).Posterior atlantoaxial transpedicular fixation was performed in 13 patients including 10 patients with old odontoid fractures and three with old traumatic transverse ligament disruptions of the atlas combined with atlantoaxial dislocations.Also,posterior atlantal arch transpediclar fixation combined with axial pedicle screw fixation was performed in three patients who had old odontoid fractures combined with atlantoaxial dislocations.All patients had simultaneous autogenous bone grafting between atlas and axis during reduction and fixation.The preoperative and postoperative Japanese Orthopaedic Association (JOA) scores were compared.Follow-up X-ray films and CT was performed to evaluate the atlantoaxial reduction and fusion.ResultsAll the patients were followed up for 9-18 months ( mean 13 months).None of the patients had spinal cord or vertebral artery injuries.Follow-up CT showed that two patients had partial penetration of one side axial pedicle screws into transverse foramen without nerve and blood vessel injuries.Clinical symptoms obtained different degree of improvement.The postoperative JOA scores ranged from 13 to 16 points ( mean 14.8 points) and the improvement rate of JOA was 71％-92％ ( mean 82％ ).The X-ray films and CT showed sound bone fusion,with good location of screws but with no signs of atlantoaxial instability or loss of reduction,or loosening or breakage of the screws.ConclusionPosterior atlantoaxial fusion fixation can effectively reconstruct atlantoaxial stability,improves neurologic function of spinal cord and has reliable curative effects.

Objective To investigate the clinical characteristics and risk factors of the incidence of herpes zoster after renal transplantation. Methods Clinical data of 830 recipients undergoing renal transplantation for the first time in the Organ Transplantation Research Institute of the 309th Hospital of Chinese People's Liberation Army from March 2009 to March 2012 were retrospectively analyzed. Univariate and multivariate Logistic regression analyses were performed to identify the risk factors of the incidence of herpes zoster after renal transplantation. Results Among 830 patients, 42 (5.1%) suffered from herpes zoster postoperatively. Clinical manifestations of herpes zoster mainly included varicella-zoster rash in the head, face, trunk and limbs. No patient died from herpes zoster. Post-herpetic neuralgia (PHN) was the most common complication of herpes zoster. Univariate Logistic regression analysis revealed that advanced age and adrenal cortical hormone (hormone) shock therapy could increase the risk of herpes zoster viral infection after renal transplantation (OR=2.414, P=0.016; OR=2.936, P=0.003). Multivariate Logistic regression analysis demonstrated that advanced age and hormone shock therapy were the independent risk factor of the incidence of herpes zoster following renal transplantation (OR=2.238, P=0.030; OR=2.755, P=0.005). Conclusions Herpes zoster after renal transplantation is clinically manifested with varicellazoster rash. Advanced age and hormone shock therapy are the independent risk factor of the incidence of herpes zoster after renal transplantation.

Objective To evaluate the predicting value of serum procaleitonin (PCT) in treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) in elderly patients. Methods A total of 267 elderly patients requiring hospitalization for AECOPD were randomly assigned into 2 groups: standard therapy group (standard group, n= 135) and PCT-guided group(PCT group, n= 132). Standard group received antibiotics according to the guideline of attending physicians and PCT group were treated with antibiotics according to serum PCT levels.Length of hospitalization, clinical efficacy, costs of hospitalization and antibiotics, rate of antibiotics use, hospital mortality, rate of exacerbation and rehospitalization, frequency of exacerbation within 1 year were observed. Results Length of hospitalization, clinical efficacy, hospital mortality, rate of exacerbation and rehospitalization, frequency of exacerbation within 1 year were similar in 2 groups(all P＞0.05);costs of hospitalization and antibiotics, rate of antibiotics use of PCT group[10 882 (3808-16 651)yuan, 6934 (2390-10 660)yuan, 76.5%] were lower than those of standard group[13 637(4650-19 730)yuan, 8589(3144-12 117)yuan, 87.4%] (all P＜0.05). Conclusions PCT guidance offers an advantage over standard therapy in reducing antibiotic use and in lowering the costs of hospitalization in treatment of AECOPD in elderly patients.
