Objective To investigate the therapeutic effect and analgesic mechanism of percutaneous vertebral angioplasty in the treatment of painful osteoporotic thoracolumbar vertebral compression fracture.Methods80 cases of patients with painful osteoporotic thoracolumbar vertebral compression fracture in Shaoxing second hospital from May 2014 to May 2016 were selected, they were randomly divided into percutaneous vertebroplasty group (40 cases) and conservative treatment group (40 cases) two groups, the clinical efficacy, VAS scores and ODI scores of the two groups were statistically analyzed.ResultsThe total treatment effective rate of the percutaneous vertebroplasty group 95% (38/40) was significantly higher than the conservative treatment group (30/40) (P<0.05);The VAS scores and ODI scores of the two groups after treatment were significantly lower than before treatment (P<0.05);The differences of VAS scores and ODI scores before treatment between the two groups were not significant.The VAS score and ODI score after treatment of the percutaneous vertebroplasty group were significantly lower than the conservative treatment group (P<0.05).ConclusionThe therapeutic effect of percutaneous vertebral angioplasty in the treatment of painful osteoporotic thoracolumbar vertebral compression fractures is more significant than conservative treatment, it has better analgesic effect, so is worthy of promotion in the clinical.

Objective To evaluate the efficacy and value of mediastinoscopy in the diagnosis of superior vena cava obstruction syndrome (SVCOS). Methods 12 patients with SVCOS underwent mediastinoscopy. This group consists of 9 males and 3 females aged 16 to 71 years. 7 cervical mediastinoscopies and 5 parasternal mediastinoscopies were performed. Results In eleven patients, definite pathological diagnosis was obtained, included: primary lung cancer in 8, lymphoma in 3 and invasive thymoma in 1. There were no operative morbidity and mortality. Only in 1 patient with lymphoma the symptom got worse after cervical mediastinoscopy and soon released by chemotherapy. Conclusion Mediastinoscopy is an effective method in the diagnosis of SVCOS.It can be considered as a routine procedure if other methods failed.

Objective:To evaluate the role of miR-124 in breast cancer and its underlying mechanism. Methods:Quantitative re-verse transcription-polymerase chain reaction (qRT-PCR) was employed to quantify the expression level of miR-124 in the breast can-cer cell lines and matched tissues of 52 patients. Cell proliferation, invasion, and migration of MDA-MB-231 and T-47D were deter-mined by miR-124 overexpression in vitro. Luciferase vectors (pMIR-SP1 3'UTR) were also constructed. The predicted target gene of miR-124 was identified via luciferase activation assay. The mRNA and protein expression of SP1 was detected via qRT-PCR and West-ern blot, respectively. Results:MiR-124 was decreased in breast cancer tissues and cell lines. This result is correlated with metastatic capacity, TMN stages, and prognosis in breast cancer tissues. In breast cancer cell lines, ectopic overexpression of miR-124 inhibited cell proliferation, invasion, and migration in vitro. MiR-124 mimics significantly inhibited luciferase activation (P<0.05) in HEK293 cells and could significantly decrease the mRNA (P<0.05) and protein expression levels of SP1 in MDA-MB-231 and T-47D cells. Con-clusion:MiR-124 could be inhibited in breast cancer. The low miR-124 expression is associated with poor prognosis. In addition, miR-124 could inhibit cell proliferation, invasion, and migration by targeting SP1. These findings confirm that miR-124 downregulation may be a key mechanism for breast cancer carcinogenesis.

Objective: To investigate the feasibility and advantages of supraclavicular approaching thyroidectomy for benign thyroid diseases. Methods: From February 2004 to December 2007, 64 cases of thyroidectomies were performed via the lateral cervical supraclavicular incision, and were selected as experimental group, of whom, there were 37 cases of thyroid adenomas and 27 cases of nodular thyroid goiters, respectively. At the same time period, 63 cases of consecutive thyroidectomies through the conventional anterior neck incision were selected as a control group, of whom, there were 39 cases of thyroid adenomas and 24 cases of nodular thyroid goiters, respectively. Results: All the operations in two groups were successfully accomplished. In the experimental group, there were 9 subtotal thyroidetomies, 40 subtotal lobectomies and 15 nodulectomies. While in the control group, there were 8 total thyroidetomies, 37 subtotal lobectomies and 18 nodulectomies. The statistical analysis between the two groups was carried out in terms of tumor size, operative time-consuming, blood loss, postoperative drain volume, time for return of motion and postoperative complications. There were no injuries of laryngeal recurrent nerve, superior laryngeal nerve and parathyroid glands. Two cases of postoperative complications in the experimental group and 3 in the control group were observed, respectively, the statistical differences were not significant between the two groups. Conclusion: The supraclavicular incision for thryoidectomy for benign thyroid diseases is a feasible and safe technique with a satisfactory cosmetic result. It is accessible to the treatment of bilateral thyroid diseases and can facilitate the detection of lymphatic metastases.

Objective To investigate the current situation and development of geriatrics in Jiangsu Province, and to find out the characteristics and trend in development of geriatrics in Jiangsu Province. Methods The literatures in geriatric field of Jiangsu Province from 1998 to 2007 were collected from the database, www. cnki.net. Bibliometric methods and Mann-Whitney Test (performed by SPSS) were used to analyze the distribution of time, area, author, fund and discipline of the literatures. Results The total number of the literatures about geriatrics of Jiangsu Province from 1998 to 2007 was 4623, accounting for 7.72% of the total number of the literatures about geriatrics of China. The number of the literatures in South Jiangsu was the highest, followed by North Jiangsu and Center Jiangsu (P＜0.001). The authors publishing only one article made up 81.51% of the total number of the authors. The literatures with cooperating affiliations made up 12.24% of the total literatures. There were 212 literatures with research sponsorship. The literatures in geriatrics of Jiangsu province covered 39 subjects, and the literatures about cardiovascular diseases accounted for 14.56%. Conclusions Geriatrics in Jiangsu province shows a slow development and an imbalance between different areas and subjects. The core author team does not exist. This suggests that Jiangsu Province should increase the investment, and carry out a large and cooperating researchplan to promote the development of geriatrics in Jiangsu province.

Influenza is a major threat to millions of people worldwide. Vaccines and antiviral agents are two main options available to reduce the impact of the influenza virus, while anti-influenza agents are the most effective means to prevent the transmission of the highly contagious virus and to treat the epidemics of disease. At present, four anti-influenza agents have been approved by the FDA for the treatment of influenza, including two M2 protein ion channel inhibitors-amantadine and rimantadine and two neuraminidase inhibitors-zanamivir and oseltamivir. Arbidol hydrochloride, launched in Russia, is a potent inhibitor of influenza virus, too. Neuraminidase inhibitors could be classified generally by structure into six different kinds: sialic acid derivatives, benzoic acid derivatives, cyclohexene derivatives, cyclopentane derivatives, pyrrolidine derivatives and natural products. In this paper, recent progress in the research of the action mechanisms and structure-activity relationships of these anti-influenza virus agents were reviewed.

Objective To investigate the effects of congenital ptosis on refractive power of the corneal surface.Methods Forty-five patients (90 eyes) with congenital ptosis in the First Affiliated Hospital of Kunming Medical University were examined from October 2013 to June 2015.Corneal topographic analysis was performed in both the ptosis and the normal eyes.The comparison between the ptotic eye and the normal eye was done according to the topographic results.Results Among 90 eyes,55 were ptotic and 35 were normal.Amblyopia was detected in 21 ptotic eyes (38.2％).No correlation was found between amblyopia and the severity of ptosis (x 2=2.617,P＞0.05).Ptotic eye showed an asymmetrical bow tie pattern (23 eyes) and an irregular pattern (32 eyes) on corneal photography and the maximum refractive power occurred at the inferior quadrant of the corneal horizontal axis.Difference value of the average refractive power of the cornea between lower side and upper side in ptotic eyes was higher than that of the normal eyes at 5mm and 7mm diameter areas (P＜0.01) except for 3mm diameter area (P＞ 0.05).Conclusion Congenital ptosis may lead to the change of refractive power of the local corneal surface.Amblyopia has no correlation with the severity of ptosis.
