Background and purpose: The miR-224 in a variety of malignant tumors is overexpression, however, its expression and function in colon cancer are not clear. The aim of this study was to investigate the expression of miR-301 in colon cancer tissues and demonstrate the regulative effects of miR-301 ASO on the proliferation and apoptosis of colon cancer cell in vitro and in vitro. Methods:The expression of miR-301 in 120 colon cancer tissues and their adjacent tissues was detected by real-time quantitative PCR method. After transfection with miR-301ASO, the biological effects of miR-301 in SW620 cells were measured by MTT assay, the colony formation experiment, flow cytometry and the in vivo experiment. Results: The expression level of miR-301 was found to be overexpressed in 63.33% (76/120) of the colon cancer cases (P<0.05). miR-301 expression in SW620 cells (transfection with miR-301 ASO, 0.09±0.01) was significantly less than control group (0.50±0.07, P=0.00). MTT assay results showed that SW620 cells survived rate at 24, 48 and 96 h decreased greatly after transfection with miR-301ASO (P=0.00). Clone formation assay revealed that miR-301 ASO group colony formation rate (5.33%±0.74%) was significantly lower than the control group (33.33%±8.38%, P=0.00). In vivo study further confirmed that miR-301ASO could inhibit the proliferation of SW620 cells (P<0.05), and miR-301ASO group grew substantially slow compared with the negative control group (P=0.00). Flow cytometry indicated that the apoptotic index in miR-301 ASO group (15.68±1.46) was significantly higher than the control group (3.36±0.88, P=0.02). In addition, the Bcl2 mRNA and protein were significantly decreased after reduce the expression of miR-301 (P=0.00, P=0.00). Conclusion:MiR-301 was overexpressed in human colon cancer. Reduce the expression of miR-301 can effectively inhibit the growth of colon cancer cells and promote apoptosis. MiR-301 may become a new target for the regulation of gene expression in colon cancer.

Objective To elucidate the clinical and pathological features, diagnosis, treatment and prognosis of nodal marginal zone B-cell lymphoma (NMZL). Methods 2 patients, with NMZL who has extremely elevated monoclonal IgM were analyzed and review were included. Results The common pathological diagnosis caused by the association of monoclonal gammopathy with indolent B-cell non-Hodgkin lymphomas was marginal zone lymphoma or B small cell lymphocytic lymphoma/B-cell chronic lymphocytic leukemia. According to our cases and literatures, the main distribution of involved sites in NMZL were lymph nodes, spleen and bone marrow. Sixty percent of the NMZL patients presented with advanced stage with, high risk of IPI. The diagnosis of NMZL was based on pathology of the lymph node. The proliferation and distribution of the differentiation monocytoid cell had a specified significance. Prognosis of early stage ( I or Ⅱ) NMZL were much better than that of advanced stage NMZL even the patients had received chemotherapy.Conclusion NMZL mainly involved lymph nodes, bone marrow and spleen, sporadically associated with the elevated monoclonal IgM. Most of the NMZL patients presented with advanced stage.The prognoses were poor.

Objective To observe the clinical efficacy of bloodletting and cupping at Fengchi (GB 20) plus acupuncture in treating peripheral facial paralysis in acute stage.Method Sixty patients with peripheral facial paralysis in acute stage (disease duration ≤7 d) were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by bloodletting and cupping at Fengchi (GB 20) plus acupuncture, while the control group was treated with ordinary acupuncture. The two groups were treated once a day, 5 times a week, 2 weeks as a treatment course and 3 treatment courses in total. The House-Brackmann (H-B) facial nerve grading system was observed before and after the intervention, and the clinical efficacies in the two groups were compared. Result The total effective rate was 96.7% in the treatment group versus 93.3% in the control group, and the difference was not statistically significant (P>0.05). There were statistically significant differences in the H-B score between the two groups respectively after 2 and 3 treatment courses (P<0.05).Conclusion Bloodletting and cupping at Fengchi (GB 20) plus acupuncture is an effective approach in treating peripheral facial paralysis in acute stage.

Objective To investigate the value of laparoscopy in comprehensive early ovarian cancer staging by comparing the feasibility and safety of laparoscopy and laparotomy in surgical staging of early-stage epithelial ovarian cancer (EOC). Methods A total of 102 patients with EOC who underwent comprehensive laparoscopic (LPS group, n=71) or laparotomic (LPT group, n=31) staging at Southwest Hospital from November 2007 to November 2014 were retrospectively analyzed. The perioperative parameters, postoperative complication rate and the long-term curative effect were compared between the two groups. Results (1)LPS group had less intra-operative blood loss [(288±239) vs (631±463) ml], lower rate of blood transfusion(14%vs 58%), larger number of pelvic dissected lymph nodes (18.1±5.6 vs 15.5± 4.6), lower vasual analogue scalescore(VAS) pain score (2.1 ± 1.6 vs 3.0 ± 1.1), shorter gastrointestinal recovery time [(2.6 ± 0.8) vs (3.5 ± 0.9) days] and shorter hospital stay [(9.9 ± 2.9) vs (11.3 ± 5.0) days] when compared with LPT group (all P<0.01). No significant difference were found in operation time, number of para-aortic lymph nodes, rate of postoperative upstaging and adjuvant chemotherapy between the two groups (all P>0.05). (2) No significant difference was found in postoperative rate of complications [11%(8/71) vs 19%(6/31),χ2=1.192, P=0.275]. (3) No significant difference was found in recurrence rate [17%(11/66) vs 14%(4/29), χ2=0.125, P=0.724] and 5-year overall survival (86.7% vs 86.8%, P=0.874). Conclusion Compared with LPT group, there are no significance differences in recurrence rate and mortality between two groups, laparoscopic staging, which could be recommended as a choice of surgical treatment of early ovarian cancer, shows more favorable operative outcomes including minimally invasive, less intra-operative blood loss, less postoperative pain and quicker recovery.

Objective To observe the corneal nerve fibres damage in different stage of diabetic retinopathy (DR) with type 2 diabetes.Methods A cross-sectional study.One hundred and twenty eyes of 120 patients with type 2 diabetes served as diabetes group.According to International Clinical Diabetic Retinopathy Disease Severity Scales (2002),diabetes patients were classified into 4 subgroups:patients without diabetic retinopathy (NDR),patients with mild or moderate non-proliferative diabetic retinopathy (mNPDR),patients with severe non-proliferative diabetic retinopathy (sNPDR) and patients with proliferative diabetic retinopathy (PDR),each subgroup has 30 eyes of 30 patients.Another 30 eyes of 30 healthy participants served as control group.All eyes were scanned with HRT3 in vivo corneal confocal microscopy.Images of sub-basal nerve plexus were quantified including nerve fiber length (NFL),nerve fiber density (NFD),nerve fiber branch density (NFB),and nerve tortuosity (NT).The correlations of corneal nerve fiber with age,duration of diabetes and glycated hemoglobin (HbA1 c) were analyzed using Spearman correlation analysis.Results NFL,NFD and NFB were found to be significantly lower in diabetic patients (F=147.315,142.586,65.898;P=0.000,0.000,0.000),NT was significantly greater in diabetic patients (F=39.431,P=0.000),when compared to control group.In diabetic patients,NFL,NFD and NFB were gradually reduced with DR severity,NT was gradually increased with DR severity.While the difference ofNFL,NFD,NFB,NT was not statistically significant between sNPDR and PDR subgroups (P＞.0.05),but was statistically significant between other subgroups (P＜0.05).Spearman correlation analysis results showed that age (r=-0.071,-0.080,0.001,0.100;P=0.391,0.328,0.991,0.224) and HbAlc (r=-0.109,-0.115,-0.126,0.025;P=0.238,0.211,0.169,0.781) had no correlation with NFL,NFD,NFB,NT.Duration of diabetes was negatively correlated with the NFL,NFD (r=-0.212,-0.264;P=0.020,0.004),positive correlated with NT (r=0.261,P=0.004),and had no correlation with NFB (r=-0.119,P=0.194).Conclusions Corneal nerve fiber loss and nerve tortuosity increased were found in patients with type 2 diabetes,and even without diabetic retinopathy.The progress of corneal neuropathy was correlated with the severity of DR,but it was not change significantly between sNPDR and PDR.

Objective To investigate gene expressions of matrix metalloprotease (MMP-2, MMP-9) and tissue inhibitor of metalloproteinase-2 (TIMP-2) and RECK ( reversion inducing cysteine-rich protein with Kazal motifs) in the liver tissue of rats with Vibrio vulnificus sepsis. Methods Vibrio vulnificus sepsis model was induced by injection of 1 mL/100 g Vibrio vulnificus (9 × 106 cfu/mL) at hind limbs in 50 Sprague-Dawley male rats of clean grade, each time 10 animals were sacrificed at 2, 6, 9, 12 and 16 h after injection and liver samples were taken. Ten rats served as control group. The ethological changes were observed. The total RNA was extracted from liver tissue and the gene expressions of MMP-2, MMP-9, TIMP-2 and RECK were evaluated by semi-quantitative RT-PCR. Results The rats manifested shortness of breath, fever and swelling in hind limbs at 4 h after injection of Vibrio vulnificus. These symptoms gradually deteriorated, and the rats presented cyanosis and convulsion at 12 h. The gene expressions of MMP-2 and MMP-9 were markedly up-regulated, while those of TIMP-2 and RECK were down-regulated. Conclusion The study suggests that the elevation of MMP-2 and MMP-9 and down-regulation of TIMP-2 and RECK is associated with the development of Vibrio vulnificus sepsis.
