ObjectiveTo explore the treatment strategies of different types of pancreatic cancer.MethodsBy reading the relevant literatures on the treatment of pancreatic cancer at home and abroad in recent years, the classification of pancreatic cancer and the progress of treatment measures were summarized.ResultsAccording to preoperative imaging evaluation, pancreatic cancer was divided into resectable pancreatic cancer, borderline resectable pancreatic cancer, locally advanced pancreatic cancer, and pancreatic cancer with distant metastasis. Resection of pancreatic cancer should be radical resection, supplemented with chemotherapy after surgery; patients with resected pancreatic cancer in the junction, if the patient with venous invasion could be resected and reconstructed, it was recommended to undergo surgery and postoperative adjuvant chemotherapy. Patients with unresectable reconstruction and arterial invasion should undergo neoadjuvant therapy, and then re-evaluate the resectability of the tumor to determine whether surgery was feasible. Patients with locally advanced or combined metastatic pancreatic cancer had lost the opportunity for surgery, for this kind of patient, advocated neoadjuvant chemoradiotherapy or second-line combined targeted therapy.ConclusionsMost patients with pancreatic cancer have progressed to the stage of clinical diagnosis. They are familiar with the treatment of different types of pancreatic cancer and take targeted treatment measures to improve the survival time of patients.
Objective To systematically review the effectiveness and safety of linezolid versus teicoplanin in patients with MRSA pneumonia. Methods Such databases as CBM, CNKI, WanFang Data, VIP, Science Direct, PubMed, Ovid, SciFinder, The Cochrane Library (Issue 3, 2013) and EMbase were electronically searched for published articles (randomized controlled trials or non-randomized prospective trials with comparable baseline between groups) at home and abroad on the clinical effectiveness and safety of linezolid versus teicoplanin in patients with MRSA pneumonia from January 2003 to March 2013. Using the Cochrane methods, two reviewers independently screened literature, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software in clinical cure rates, clinical effective rates, microbiologic eradication rates, and adverse reaction incidences. Results Finally, 7 studies were included involving 637 patients. The results of meta-analysis were clinical effective rates (RR=1.17, 95%CI 1.04 to 1.32, P=0.009), clinical cure rates (RR=1.06, 95%CI 0.94 to 1.19, P=0.37), bacterial clearance rates (RR=1.32, 95%CI 1.03 to 1.68, P=0.03), and adverse events rates (RR=1.24, 95%CI 0.78 to 1.97, P=0.37). The results of Begg test and Egger test were not significant (Pgt;0.05). Conclusion Current evidence shows that, in treating MRSA pneumonia, linezolid is better than teicoplanin in clinical effective rates and bacterial clearance rates. However, they are alike in clinical cure rates and bacterial clearance rates.
【摘要】 目的 原肌球蛋白是肌球蛋白主要相关蛋白之一，在细胞骨架与运动中起着重要的作用。探讨原肌球蛋白在增生性瘢痕中的作用，有助于揭示瘢痕挛缩的产生机制。 方法 收集2006年3月-2008年7月48例患者不同时期增生与非增生瘢痕组织标本，利用基因芯片筛选出的瘢痕相关基因——原肌球蛋白基因特异片段，制备成寡核苷酸探针与瘢痕组织切片进行原位杂交。同时，将各标本进行原代细胞培养，制备成纤维细胞爬片，进行原位杂交。 结果 原肌球蛋白基因在3、6个月的增生性瘢痕中表达均明显强于9、12个月增生性瘢痕及非增生性瘢痕，阳性细胞比例也高于9、12个月增生性瘢痕及非增生性瘢痕。 结论 瘢痕增生挛缩与细胞骨架运动的相关基因存在密切关系，而原肌球蛋白可能在其中起着重要作用。【Abstract】 Objective Tropomyosin is one of the proteins of cytoskeleton and cell movement. The aim of this study is to investigate the effect of gene expression of fibroblast tropomyosin on the formation and contraction of hypertrophic scar. Methods According to the results of differently expressed genes, in hypertrophic scar by gene microarray, topomyosin, one of the most important genes, was selected and made into oligonucleotide probe. Twenty-four hypertrophic scars and 24 non-hypertrophic scars and 12 normal skins were used and these scar were taken on 3, 6, 9, and 12 months after burned between March 2006 and July 2008. Frozen section and cultured fibroblasts were made to detect the expression of the gene by in situ hybridization. Results Expression of tropomyosin was defected in scar tissue, but those in the hypertrophic scar on 3 and 6 months after burn were significantly ber than those in the hypertrophic scar on 9 and 12 months after burn and non-hypertrophic scar. Conclusion Overexpression of cytoskeletal relative genes causes the contraction of scar and tropomyosin acts leading and key functions.
ObjectiveTo investigate the diagnosis and treatment of primary thyroid lymphoma.MethodThrough reading of relevant literatures at home and abroad in recent years, the diagnosis and treatment progress of primary thyroid lymphoma were summarized.ResultsThe pathogenesis of primary thyroid lymphoma was associated with chronic inflammatory stimuli such as Hashimoto’s thyroiditis. Its preoperative diagnosis mainly relied on ultrasound-guided biopsy. The treatment depended mainly on its pathological type and tumor stage. Surgical resection was mainly used for pathological biopsy and relieving compression symptoms, and radiotherapy and chemotherapy were the main treatments.ConclusionsPrimary thyroid lymphoma is a rare thyroid malignancy. Being familiar with and understands its clinicopathological features have important guiding significance for preoperative diagnosis, clearing pathological type and staging, and selection of reasonable treatment measures.
