To evaluate the clinical therapeutic effect of the autologous bone marrow mesenchymal stem cells grafting integrating blood plasma transplantation in treatment of problematic nonunion. In March 2000, a 29-year-old man presented complaints of painful walking of left thigh after a velocity injury, was selected. Radiography revealed a left femoral shaft fracture, and the bone defect distance was 5 mm through X-ray examination before operation. Following a series of reposition, fixation, intramedullary nail fixation and twice autogenous lilac bone graft treatment, external fixator and autogenous lilac bone graft treatment, totally four times, the fracture was not healed. He come to Orthopaedic Surgery Department of Siping Central Hospital to accept the autologous bone marrow mesenchymal stem cells grafting integrating blood plasma transplantation in March 2008. Under the small C-arm X-ray perspective, 4 mL bone marrow-derived mesenchymal stem cells suspension integrating 10% autologous blood plasma was injected vertically into fracture site from the skin in front of the thigh with epidural needle, and the stem cells density was 1.8 × 107 cells/L. X-ray examination was performed though out-patient recheck to observe fracture healing. Two months after graft, radiography results showed fracture interspace reduced, left femoral shaft callus was continual and fracture lines blurred partly of the left femur; furthermore, left femoral shaft fracture lines blurred, and continuous bone callus formation of the left femur at 4 months after graft; The left femur achieved bone union within 7 months. The patient was returned to full weight bearing walking and good function with a fully healed femoral bone, without any fever or infection. Percutaneous transplantation of autologous bone marrow stem cells for treatment of problematic nonunion has the satisfactory result.

Objective To investigate the clinical characteristics of pulmonary hypertension(PH) in patients with chronic obstructive pulmonary disease (COPD) and study the related risk factors.Methods Patients with stable COPD enrolled in this study,undergoing examinations including full pulmonary function tests (PFT),6-minute walk distance (6MWD),Exercise Oxyhemoglobin,Saint.George's respiratory questionnaire (SGRQ) and transthoracic echocardiography.Pulmonary artery systolic pressure (sPAP) ≥ 36 mmHg(1 mmHg =0.133 kPa) was defined as PH.Results A total of 251 patients were finally evaluable in this study.The frequency of PH was 55.4％ (139/251) in patients with stable COPD.Significant differences were seen between patients with PH and without PH respectively in the following factors (mean P ＜0.05):proportion of age ≥ 60 years (69.8％ vs 57.1％),forced expiratory volume in one second (FEV1)(％ predicted) [(47.5±8.2)％ vs(61.2±10.2)％ and(49.8±7.9)％ vs(66.4±11.3)％],sPAP [(41.9 ± 9.1) mmHg vs (28.2 ± 3.2) mmHg],exercise oxyhemoglobin desaturation [(-5.5 ± 3.2) ％ vs(-2.2 ± 1.2) ％],6MWD [(316.0 ± 55.2) m vs(390.0 ±75.2) m].The following variables were negatively correlated with sPAP:6MWD (r =-0.330,P =0.003),FEV1 (％ predicted) (r =-0.210,P =0.024 and r =-0.130,P =0.012,respectively).The following variables were positively correlated with sPAP:age(r =0.560,P =0.031),exercise oxyhemoglobin desaturation ＞ 3％ (r =0.540,P =0.001).Logistic regression test has showed that age≥ 60 years,exercise oxygen desaturation ＞ 3％,FEV1 (％ predicted) ＜ 50％,6MWD ＜ 350 m were risk factors for PH in COPD.Conclusion The incidence of PH in COPD increases with age,yet the performance of lung function and the activity of endurance decrease in elder patients.Sixty years or older,exercise oxygen desaturation ＞ 3％,FEV1 (％ predicted) ＜ 50％,6MWD ＜ 350 m are risk factors of PH in COPD.Echocardiography or right heart catheterization when needed should be considered to confirm the diagnosis.

OBJECTIVE To investigate the carotid artery invasion in patients with head and neck malignant tumor with multislice helical CT and MPR. METHODS Thirty-six tumors adjacent to the carotid artery in head and neck were studied using 16 slice helical CT scanner.The following two parameters were measured:tumor-artery angle(the angle surrounded by the tumor)and tumor-artery ratio(the ratio between the length of intersection of the tumor with carotid and the diameter of the carotid).RESULTS Tumor-artery angle:in judgment of carotid involvement with axial CT,the accuracy of the tumor-artery angle≥90?group and the tumor-artery angle≥180?group were higher than that of the tumor-artery angle≥45?group (P

Objective: To analyze the relationship between the baseline BMI level and body mass index (BMI) changes of primary and middle school students and the blood pressure level and the risk of elevated blood pressure after 8 years of follow up(also known as the end stage), so as to provide a basis for the prevention and control of blood pressure in children and adolescents. Methods: The physical examination data of 9 748 primary and secondary school students were selected from a cohort study design in Longkou City, Shandong Province for 8 years from 2014 to 2022, and analyzed the association of baseline BMI level and BMI changes with end stage blood pressure level and the risk of elevated blood pressure. Chi square test was used to compare differences between groups, and the generalized linear model and Logistic regression model were used to analyze the effect of baseline BMI level and BMI changes on blood pressure level and elevated blood pressure after 8 year follow up. Results: Among non overweight and obesity group at baseline, the prevalence of high blood pressure was 9.1%. Among the overweight and obesity group, the prevalence of high blood pressure was 12.0%. Under different BMI status at baseline, the incidence of high blood pressure in boys was higher than that in girls. Compared with the BMI Z value≤-1 group, with the increase of BMI Z value, the systolic blood pressure level and the risk of high blood pressure gradually increased; with the BMI change continuously low as the control, sustained high and increased groups showed an increased risk of end stage high blood pressure ( OR=4.00, 2.21, P <0.01), and boys had a greater risk of elevated blood pressure. Conclusion Children and adolescents with higher baseline BMI level and increased BMI changes are at a higher risk of elevated blood pressure. Therefore, secondary school students should monitor the occurrence and development of blood pressure level in real time, and take comprehensive and effective measures to control the occurrence of elevated blood pressure level in childhood.

Objective? To analyze the correlation between oral health literacy and disease severity in patients with periodontitis and to understand the influencing factors for oral health literacy. Methods? Totally 191 patients with periodontitis attending the outpatient or inpatient service of the Department of Stomatology, Peking University Third Hospital from January 2016 to January 2018 were selected. Their general information was collected, and the Oral Health Literacy Adults Questionnaire (OHL-AQ) was used to investigate their oral health literacy. The severity of their periodontitis was evaluated according to the indicators as recommended by the Center for Disease Control of the American Academy Periodontology (CDC-AAP). The difference in oral health literacy between patients with different general information. SPSS 22.0 software was used for statistical analysis. Correlation analysis was used to analyze the correlation between oral health literacy and periodontitis severity. Multiple linear regression analysis was used to explore the influencing factors of oral health literacy. Results? Totally 74 sustained mild periodontitis, 60 moderate periodontitis, and 57 severe periodontitis among the 191 patients with periodontitis. The OHL-AQ scores were (14.55±2.59), (11.26±2.41) and (10.25±2.30), respectively (F=31.705,P＜ 0.01). Correlation analysis showed that the severity of periodontitis was negatively correlated with oral health literacy (r=-0.692,P＜ 0.01). There were statistically significant differences in oral health literacy between patients with different age, educational background, monthly household income, occupation and marital status (F/t=6.054, 51.812, 49.936, 2.594, 2.107; P＜ 0.05). Multiple linear regression analysis showed that age, educational background and monthly household income were the influencing factors for oral health literacy (P＜ 0.01). Conclusions? The severity of periodontitis can be ameliorated by improving the patients' oral health literacy. Age,educational background and monthly household income were the influencing factors for oral health literacy.

Objective To investigate the relationship between the expressions of osteopontin (OPN), matrix metalloproteinase 2 (MMP-2) and vascular endothelial growth factor (VEGF) in gastric cancer and the poor prognosis of gastric cancer patients. Methods A total of 35 patients with gastric cancer after radical gastrectomy from January 2014 to March 2015 in Dalian Third People ' s Hospital were retrospectively analyzed. The expressions of OPN, MMP-2 and VEGF in gastric cancer tissues and adjacent normal tissues were detected by immunohistochemical SP staining. The relationship between the expressions of OPN, MMP-2 and VEGF and the poor prognosis of gastric cancer patients was analyzed. Results The positive expression rates of OPN, MMP-2 and VEGF in postoperative pathological tissues of gastric cancer were 80.0％ (28/35), 77.1％(27/31) and 88.6％(31/35), respectively. OPN expression was associated with vascular invasion, lymph node metastasis, degree of differentiation, degree of invasion, and Lauren classification (all P< 0.05). MMP-2 expression was associated with vascular invasion, lymph node metastasis, and degree of invasion (all P<0.05). VEGF expression was associated with vascular invasion, lymph node metastasis, degree of invasion, and Lauren classification (all P< 0.05). OPN, VEGF and MMP-2 had synergistic effects in the invasion and metastasis of gastric cancer, and the expressions of them were positively correlated (all P< 0.05). The sensitivity of combined detection of OPN, VEGF and MMP-2 (87.5％) was higher than the sensitivity of individual detection (68.8％, 62.5％ and 56.3％) (P< 0.05). Conclusions OPN, MMP-2 and VEGF expressions are closely related to the poor prognosis of gastric cancer patients, and have synergistic effects in the invasion and metastasis of gastric cancer. The combined detection of OPN, MMP-2 and VEGF may have a more accurate prediction of the prognosis of gastric cancer.
