Colorectal cancer (CRC) is one of the most common digestive system neoplasms in China. Recently, the morbidity and mortality rates of CRC continue to increase with the improvement of people's living standard and the change of the dietary structure. It was accepted that the etiology of colorectal cancer is a multi-factor and multi-step process. However, the mechanism of CRC is still unclear. MicroRNAs (miRNAs) are a class of -21 nucleotide non-coding RNAs and function as a negative regulator of gene expression after transcription, participating in tumor angiogenesis, tumor cell proliferation and invasion. MicroRNA-21 (miR-21), as an important oncogenic RNA, plays a vital role in the development and progression of CRC. This review summarizes the advances in research on miR-21 in colorectal cancer.

Objective To investigate the association of the SNP in miRNA146A with genetic prediposion and earlier recurrence after resection for hepatocellular carcinoma (HCC).Methods In the casecontrol study including 173 HCC cases,DNA were exacted from cancer tissue embedded with paraffin and were amplificated by PCR,SNP was explored in gene sequence of miRNA146a (385 base pair including extron).The outcome were analyzed with genetic prediposion and clinical features.Result Only hsa-mir-146a rs2910164 was found.The genetype frequence of C/C 、G/G and C/G at rs2910164 gene locus were separately 61 (35.3％),21 (15％) and 86(49.7％) in cases.Compared to G/G genetype,C/C and C/G genetype were danger factor to onset risk of HCC (OR =3.086,95％ CI:1.289-7.390) ; C/G was danger factor to earlier recurrence after resection(OR =8.179,95％ CI:2.248-29.759).Conclusion rs2910164 may be associated with genetic prediposion and earlier recurrence after resection of HCC in Jiangxi hans

BACKGROUND:With elevated medical levels, limb salvage surgery for limb malignant tumor is valuable day by day. At present, the limb salvage surgery has substituted amputation and becomes mainstream and development direction of present surgical treatment of limb tumors. However, so far, there are no unified surgical indications for proximal femur tumor, which are controversial. OBJECTIVE:To investigate the efficacy of artificial total hip arthroplasty combined with extended resection of tumor sections for proximal femoral bone tumors. METHODS:Patients with proximal femoral bone tumors in the Second Xiangya Hospital of Central South University were selected and divided into control group and observation group, with 30 patients in each group. According to the disease, lesion curettage, aneurysm wal inactivation, autologous and (or) al ogeneic bone, mixed bone graft and bone graft fixation were selected to treat the control group. The observation group patients received extended resection of tumor sections and total hip arthroplasty. The operative time, intraoperative blood loss, hospital stay and joint function of two groups were compared. 2 years later, patients were revisited. Metastasis and recurrence rate, death rate and quality of life of two groups were compared. RESULTS AND CONCLUSION:There was no significant difference in intraoperative blood loss and surgery time between the two groups (P>0.05). However, hospital stay of patients in the observation group was shorter than the control group. The excellent and good rate of recovery of joint function (83%) was higher in the observation group than in the control group (53%). The metastasis and recurrence rate within 2 years after surgery (7%) and death rate (3%) were lower in the observation group than in the control group (30%, 23%). Various indicators of quality of life of patients in the observation group were significantly better than the control group (P<0.05). These results confirmed that artificial total hip arthroplasty in the treatment of proximal femur tumors is safe and effective.
