OBJECTIVE: To investigate the efficacy and related factors of nasal surgery combined with upper air way radiofrequency ablation(RFA) for treatment of obstructive sleep apnea hypopnea syndrome (OSAHS) with chronic nasal blockage. METHOD: One hundred and three mild or moderate OSAHS patients with chronic nasal blockage were recruited, all cases had nasal surgery and upper airway RFA. All patients were evaluated by body mass index (BMI), Epworth sleep scale (ESS), snoring scale, and nocturnal polysomnography (PSG). Eighty-nine patients were reevaluated at least 6 months after surgery with the preoperative methods. RESULT: After operation, the apnea and hypopnea index (AHI) decreased from (18.67 +/- 9.48)/h to (9.22 +/- 7.18)/h; the lowest artery oxygen saturation (LSaO2) increased from (0.83 +/- 0.08) to (0.92 +/- 0.06); the Epworth sleep scale(ESS) decreased from (8.74 +/- 5.67) to (5.12 +/- 3.74); the snoring scale decreased from (7.16 +/- 2.85) to (3.56 +/- 2.26), the percentage of time with oxyhemoglobin saturation below 0.90 (CT90) decreased from (18.64 +/- 12.98) to (10.73 +/- 8.29). All of the differences were obvious (P<0.01). Success was defined as a postoperative apnea-hypopnea in dex < 10 events per hour and at least 50% less than the preoperative value. The surgical success rate was 75.3% (67/89). No major perioperative complications occurred. CONCLUSION Our findings suggest that nasal surgery combined with upper airway RFA can improve snoring and disease-specific quality of life in patients with anatomic na sal obstruction with mild or moderate OSAHS.

BACKGROUND: Percutaneous vertebroplasty for osteoporotic vertebral compression fractures has achieved very good results, but its long-term efficacy as well as impact on patients has been rarely reported so far.OBJECTIVE: To investigate the long-term effect of vertebroplasty with bone cement on osteoporotic vertebral compression fractures through a follow-up.METHODS: Thirty-four patients with osteoporotic vertebral compression fractures who had undergone percutaneous vertebroplasty were recruited. Visual analogue scale scoring was measured and compared as well as lesioned vertebral height and kyphosis angle shown on lateral X-ray examination prior to, 1 week and 6 years after percutaneous vertebroplasty.RESULTS AND CONCLUSION: The kyphosis angle was improved 1 week and 6 years after percutaneous vertebroplasty, and it changed insignificantly during the follow-up period. The vertebral height was also improved significantly after percutaneous vertebroplasty (P < 0.01); however, there was no obvious variation in the vertebral height at 1 week and 6 years after percutaneous vertebroplasty. The visual analogue scale exhibited an improvement after percutaneous vertebroplasty (P < 0.01); however, with time going by, the scoring on the visual analogue scale had an increased tend. All the parameters remained stable and had no large fluctuations. It is proved that the percutaneous vertebroplasty is effective and safe to treat osteoporotic vertebral compression fractures with an excellent long-term effect.

Obje:ctive To establish an optimized method to isolate, culture and identify human umbilical cord mesenchymal stem cells (hUCMSCs) in vitro and induce their osteogenic and adipogenic differentiation. Methods The hUCMSCs were isolated from human umbilical cord by digestion with collagenase. After serial subcultivation in vitro, the stem cells were passaged. Morphologic appearance of hUCMSCs was observed under an optical microscope and atomic force microscope. The proliferation rate was measured by MTT assay. Cell cycle and surface antigens were measured by flow cytometry. The osteogenic and adipogenic differentiation was tested and evaluated by specific staining methods. Results The isolation of hUCMSCs by digestion with collagenase was efficient. After seeded for 24 hours, the adherent cells showed spindle shape and fibroblast cell-like shape and the size of hUCMSCs was homogeneous. The similar growth curves of passage 3 and 7 exhibited a great potential for proliferation. Flow cytometry analysis revealed that CD29, CD44 and CD105 were highly expressed on the surface of passages 3 cells, but the expression was negative for CD34, CD45 and HLA-DR. After culture in inducing medium, the cells were successfully induced into osteogenic and adipogenic lineages. These cells were highly positive for alkaline phosphate staining and also showed mineralization presented with von kossa staining after 4 weeks' culture induction of osteogenic differentiation. Furthermore, liquid vacuoles were detected by oil red O staining after 3 weeks' culture induction of adipogenic differentiation. Conclusion An in vitro method for isolation and purification of hUCMSCs from human umbilical cord has been established. The cultured cells were composed of only undifferentiated cells and their biological properties were stable. The hUCMSCs are expected to be a new type of stem cells of tissue engineering.

Small cell lung cancer is the most common primary neuroendocrine malignancy of the lung and is characterized by high malignant degree,rapid doubling time,easy metastasis in early stage and poor prognosis.Accurate staging of small cell lung cancer can formulate personalized therapeutic plans and improve the prognosis of patients.PET/CT can obtain metabolism and anatomical images of the whole body in one scan and improve the diagnostic accuracy and integrity.PET/CT has been widely applied to clinical practice now.PET/CT will play a more and more important role in diagnosis,staging,treatment and prognosis assessment of patients with small cell lung cancer.The value of PET/CT in staging and treatment of small cell lung cancer was reviewed in this article.

Objective To study the differentiation types of microglia induced by macrophage colony-stimulating factor (M-CSF).Methods Rat microglia cultured in vitro were inoculated on 6-well plates and divided into 3 groups (n=4 each) using a random number table method when cell confluence reached 70％:blank control group (C group),vehicle control group (P group) and M-CSF group.Group P was incubated with phosphate buffer solution for 7 days and group M-CSF with 20 ng/ml M-CSF for 7 days.The expression of a specific M1 phenotype marker tumor necrosis factor-alpha (TNF-α) and specific M2 phenotype markers interleukin-10 (IL-10) and brain-derived neurotrophic factor (BDNF) was determined by Western blot.Results Compared with C group,the expression of IL-10 and BDNF was significantly upregulated (P＜0.05),and no significant change was found in TNF-α expression in M group (P＞0.05),and no significant change was found in the expression of TNF-α,IL-10 or BDNF in P group (P＞0.05).Conclusion M-CSF can induce microglia to differentiate into a M2 phenotype.
