The mechanism of RNA interference for hepatocellular carcinoma treatment / 国际肿瘤学杂志

Primary liver cancer is one of the common malignant tumors.However, the efficacy of traditional treatments is not satisfactory.RNA interference is a new treatment method, which develops rapidly in recent years.It has been found that RNA interference can exert the anti-tumor effect through inhibiting the growth and proliferation of hepatocarcinoma cells, promoting apoptosis, inhibiting the invasion and metastasis of hepatocarcinoma cells, inhibiting angiogenesis and overcoming the resistance to chemotherapy.

Prospective Evaluation of Pharmacogenomics and Metabolite Measurements upon Azathioprine Therapy in Inflammatory Bowel Disease: An Observational Study.

Up to approximately 40% to 50% of patients discontinue thiopurine therapy during the course of inflammatory bowel disease (IBD). We investigated the role of the metabolite thiopurine in IBD treatment. This was a prospective study. IBD patients receiving azathioprine (AZA) were prospectively included. Thiopurine methyltransferase (TPMT) genotypes were examined before therapy, and thiopurine metabolite levels were examined at weeks 2, 4, 8, 12, 24, and 48. In total, 132 patients were included. The frequency of leucopenia increased at 6-thioguanine nucleotide (6-TGN) levels ≥420  pmol/8 × 10(8) RBC (odds ratio [OR] = 7.9; 95% confidence interval (95%CI): 3.5-18.0; P < 0.001) and increased more during the initial 12 weeks of thiopurine therapy (OR = 16.0; 95%CI: 5.7-44.9; P < 0.001). The patients with 6-TGN levels ≥420 pmol/8 × 10 RBC at weeks 4, 8, and 12 had an increased likelihood of leucopenia. Clinical response increased at 6-TGN levels ≥225 pmol/8 × 10(8) RBC (OR = 13.5; 95% CI: 3.7-48.9; P < 0.001) in Crohn disease (CD) patients. The CD patients with 6-TGN levels ≥225 pmol/8 × 10(8) RBC at weeks 8, 12, and 24 had an increased likelihood of successful clinical response. TPMT*3C had a specificity of 100%, but a sensitivity of 8% for predicting leucopenia.A 6-TGN level between 225 and 420 pmol/8 × 10(8) RBC could be a therapeutic window in patients receiving AZA therapy, and it could likely predict leucopenia in the initial 12 weeks of AZA therapy and a reasonable chance of successful clinical response in CD patients. The value of TPMT genotyping before thiopurine therapy is limited in Chinese patients with IBD, considering the low sensitivity of predicting leucopenia.

[Reconstruction of tibial exposure with local muscular flap, VSD and skin transplantation].

OBJECTIVE: To investigate the treatment for tibial exposure wounds. METHODS: 39 patients with tibial exposure wounds were divided into three groups according to the exposure location (upper, medium and below). The local muscular flaps were designed to cover the tibial exposure, followed by skin grafts and VSD. VSD was removed one week later. RESULTS: All the muscular flap and skin graft survived. Mild epidermis erosion happened in 2 cases, which healed spontaneously after dressing. The patients were followed up for 3-6 months with good healing and no walking malfunction. CONCLUSIONS: The local muscular flap combined with skin graft and VSD is a simple and effective method for tibial exposure wound with short healing time and high successful rate.

[The role of continuous vacuum sealing drainage in the prevention of lymph leakage after inguinal lymph nodes dissection].

OBJECTIVE: To investigate the clinical application of the vacuum-sealing drainage (VSD) in the prevention of lymph leakage after inguinal lymphadenectomy. METHODS: From September 2003 to September 2013, 60 cases who underwent inguinal lymph nodes dissection received VSD (n = 30), or traditional pressure dressing and drainage( control group, n = 30) after operation. The flap blood supply, healing process and incidence rate of lymph leakage were observed. RESULTS: Twenty-eight cases in VSD group were effective. Eleven cases were cured, ten cases were effective, and nine cases were invalid in control group. The cure rate, effective rate and healing period were significantly different between the two groups (P < 0.01). CONCLUSIONS: The incidence of lymph leakage after inguinal lymphadenectomy can markedly decrease with VSD application. VSD could be an ideal preventive method for post-operative lymph leakage.

The analysis of factors associated with progression of isolated terminal ileal lesions.

OBJECTIVE: To assess the factors associated with the progression of isolated terminal ileal lesions (ITILs) at colonoscopy in Chinese patients. METHODS: Patients diagnosed with ITILs were enrolled. The ileoscopy was performed by two experienced gastroenterologists every 52 weeks. A logistic regression analysis was used to elucidate the factors associated with Crohn's disease (CD) and mucosal healing. A log rank test was used to assess the differences of the cumulative proportion of CD and mucosal healing in different groups at different times. RESULTS: (1) A total of 34 patients were included and no patient had taken nonsteroidal anti-inflammatory drug in the last 6 months; eight (23.5%) patients had a clinical diagnosis of CD, 14 (41.2%) patients achieved mucosal healing, and 12 (35.3%) patients showed no significant changes in the lesions at last follow-up. (2) The logistic regression analysis showed that only abdominal pain was a factor in the ITIL disease outcomes. (3) The cumulative proportion of CD in the abdominal pain group after 3 years was statistically higher than that in the non-abdominal pain group (42.7% vs. 6.2%, χ2 = 10.129, P = 0.001). However, the cumulative proportion of mucosal healing in the non-abdominal pain group was statistically higher than that in the abdominal pain group (73.3% vs. 5.6%, χ2 = 5.225, P = 0.022). (4) The numbers of lesions observed on the initial colonoscopy exams and the initial histologic findings were not related to the ITIL disease outcomes. CONCLUSIONS: Clinical symptoms may be related to ITIL disease outcomes. Patients with abdominal pain had a high likelihood of CD, whereas those without abdominal pain had a high likelihood of mucosal healing.
