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: The aim of this study is to investigate the expression of hypoxia inducible factor-1alpha (HIF-1alpha), vascular endothelial growth factor (VEGF) in laryngeal carcinoma and its relations to clinical and pathophysiological characteristics, and determine the effect of HIF-1alpha, VEGF in the processing of angiogenesis. To offer the theoretical basis for the pathogenesis of laryngeal carcinoma and the new ideas for early diagnosis of laryngeal carcinoma. METHOD: The major was divided into two groups:60 specimens of laryngeal carcinoma and 20 specimens of normal tissues beside the carcinoma. The expression of HIF-1alpha, VEGF was detected in 60 specimens of laryngeal carcinoma tissues and 20 specimens of normal tissues beside the carcinoma as controls by immunohistochemical staining technique. Microvessel was stained by antifactor CD105 antibody to analyse microvessel density. RESULT: Positive rate of HIF-1alpha and VEGF protein expression was 71.67% (43/60) and 65.00% (39/60) respectively in laryngeal carcinoma tissues, which was significantly higher than that in normal laryngeal tissues (10.00% and 20.00%, respectively). HIF-1alpha expression was closely related to P-TNM stage, the grade of cell differentiation and lymph node status; VEGF expression was closely related to P-TNM stage and lymph node status. The coincidence rate of the expression of HIF-1alpha and VEGF was 56.67% (34/60), showing a close relation between them. MVD was much higher in tumor with HIF-1alpha(+)/VEGF(+) than that in tumor with HIF-1alpha(--)/VEGF(--) (P < 0.01). CONCLUSION HIF-1alpha protein and VEGF was over-expressed in laryngeal carcinoma. The positive expression of HIF-1alpha, VEGF and MVD in laryngeal carcinoma have a synergistic effect on the neovascularization of the tumor.

Objective To investigate the incidence of adverse drug reaction (ADR)in patients in a hospital,and evaluate ADR-related factors,so as to provide references for the prevention of ADR and reducing of risk factors in drug use. Methods 223 clinically reported ADR cases were collected from January 1,2011 to December 31,2011, patients'age,types and administration routes of drugs relating to ADR,and ADR-involved organs and systems were analyzed.Results Of 223 patients with ADR,211(94.62% )received intravenous drip,3 received intravenous injec-tion,2 received intramuscular inj ection,and 7 received oral administration. ADR mainly occurred within 1-30 mi-nutes after taking the medicines,39(17.49% )occurred within 1-4 minutes,45(20.18% )within 5-9 minutes,80 (35.87% )within 15-29 minutes. Of organ or system involved by ADR,skin and its appendage damages were com-mon (93 cases),followed by gastrointestinal tract (62 cases)and systemic damage (45 cases);single organ and sys-temic damage were most common (184 cases,82.51% ). 123 cases (55.16% )of ADR were caused by antimicrobial use,60 cases (26.91% )were induced by Chinese medicine injection;Of top 10 ADR-inducing medicines,7 were an-timicrobial agents and 3 were traditional Chinese medicine injections,levofloxacin lactate and sodium chloride injec-tion ranked first(23 cases,10.31% ).Conclusion The occurrence of ADR is related to multiple factors,reporting and surveillance of ADR should be strengthened,the use of antimicrobial agents and traditional Chinese medicine should be rational,thereby reduce the occurrence of ADR.

OBJECTIVE: To study the hearing characteristics in patient with posterior circulation transient ischemic attack (PCTIA). METHOD: Sixty-two patients diagnosed by neurologist were selected as experimental group for testing of pure tone audiometry, tympanometry, otoacoustic emissions (OAE) and auditory brainstem response (ABR). Thirty healthy subjects were chosen as control group. The data were compared between the PCTIA groups and the control group using the SPSS 14.0 software. RESULT: (1) The difference in pure tone threshold across 125 to 8000 Hz between the PCTIA group and the control group was not statistically significant (P>0.05); (2) In PCTIA patients, the prevalence of TEOAE was only 42.7%, significantly different from the control group; (3) The patients had longer ABR latency and wave interval than the normal controls (P<0.01). CONCLUSION Brain-stem and cochlear damage can occur in patients with PCTIA. These results suggest that OAE and ABR be used as important diagnostic test for patients with PCTIA, and might be helpful in localizing abnormality in PCTIA.
