Objective To explore the effective measurements of integrated therapy for the ear keloids in the Oriental. Methods Surgical excision was performed for keloid, and the cut then sutured directly or with flap transfer. At early stage of surgery (within 24 hours), X-ray or electron-ray radiotherapy was used for 3-5 times once daily; and steroids injected after cutting lines at 7th day every two weeks and gradually ended. Results A total of 48 patients were treated, and followed, in which 12 patients were lost of follow-up. The total effective rate was 94. 4 % based on the data of follow-up in 36 patients for 1-3 years. Therefore, the curation rate was 83. 3 % (30 cases) and effective rate 11. 1 % (4 cases). Conclusions Surgical cutting combined with early radiotherapy and steroids injection is the effective integrated therapy for the ear keloids in the Oriental.

PURPOSE: Accumulating evidence has shown that dysregulation of microRNA-191 (miR-191) is closely associated with tumorigenesis and progression in a wide range of cancers. This study aimed to explore the potential role of miR-191 in esophageal squamous cell carcinoma (ESCC). MATERIALS AND METHODS: miR-191 expression was assessed in 93 ESCC tissue specimens by real-time polymerase chain reaction, and survival analysis was performed via Kaplan-Meier and Cox regression analyses. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, plate colony-forming, BrdU, and Transwell assays were conducted to observe the effect of miR-191 on ESCC proliferation and invasion. Luciferase reporter and western blot assays were taken to identify target genes of miR-191. RESULTS: miR-191 was overexpressed in 93 cases of ESCC, compared with adjacent normal tissues, and miR-191 expression was significantly related to differentiation, depth of invasion, TNM stage, lymph node metastasis, and distant metastasis of tumor. Kaplan-Meier and Cox regression analyses demonstrated that overexpression of miR-191 was an independent and significant predictor of ESCC prognosis. Both gain-of-function and loss-of-function experiments showed that miR-191 promoted ESCC cell proliferation and invasion activities in vitro. Early growth response 1 (EGR1), a tumor suppressor, was predicted as a direct target of miR-191. Luciferase reporter and western blot assays proved that miR-191 reduced EGR1 expression by directly binding its 3' untranslated region. Moreover, EGR1 knockdown by siRNA enhanced ESCC cell growth and invasion. CONCLUSION: Our findings provide specific biological roles of miR-191 in ESCC survival and progression. Targeting the novel miR-191/EGR1 axis represents a potential new therapeutic way to block ESCC development.

Objective To investigate the changes and clinical significance of serum tumor markers in patients with non-small cell lung cancer before and after gefitinib targeted therapy.Methods 80 cases of non-small cell lung cancer patients in our hospital from June 2015 to May 2017 were divided into control group and observation group randomly,40 cases in each group.The control group were treated with docetaxel conventional chemotherapy,and the observation group were treated with gefitinib targeted therapy.The clinical treatment effect,changes of serum tumor markers cancer antigen125 (CA125),carcinoembryonic antigen (CEA),neuron specific enolase (NSE) and adverse reactions were observed and compared between the two groups before and after treatment.Results The effective rate and disease control rate of the observation group were higher than that in the control group,with statistically significant difference (P ＜ 0.05).The levels of serum tumor markers CA125,CEA and NSE in the control group and the observation group before treatment were not significantly different (P ＞ 0.05).After 1 months of treatment,the levels of serum tumor markers CA125,CEA and NSE in the two groups were all decreased,and the level of serum tumor markers,CA125,CEA and NSE in the observation group were lower than those in the control group,with statistically significant difference.The incidence of adverse reactions in the observation group was lower than that in the control group (P ＜ 0.05),with statistically significant difference.Conclusions Gefitinib is effective in the treatment of non-small cell lung cancer.It reduces the level of serum tumor markers CA125,CEA,NSE,and reduces postoperative adverse reactions.It is worthy of clinical application.
