China Oncology 2014;(7):507-511
Background and purpose: MicroRNA(miRNA) is a class of small non-coding RNA playing an important regulatory role in many diseases. In this study, we explore the levels of miR-192 and zinc ifnger E-box binding homeobox 2 (ZEB2) in CRC, the clinical signiifcance of miR-192 and the correlation between the expression of miR-192 and ZEB2 protein. Methods: The expression levels of miR-192 and ZEB2 mRNA in 30 colorectal carcinoma samples, 30 corresponding cancer-adjacent tissue samples (from the edge of tumor≥5 cm), 25 colorectal adenoma samples, and 15 normal tissue samples were quantiifed using quantitative real-time polymerase chain reaction (qRT-PCR). ZEB2 protein expression was determined using Western blot. The relationship between the miR-192 and clinicopathological factors, miR-192 and ZEB2 protein expression was analyzed. Results:Signiifcant upregulation of miR-192 expression and reduction of ZEB2 mRNA and protein expression were identiifed in CRC tissues, compared to cancer-adjacent tissues, colorectal adenoma samples, and normal tissues (P<0.05). Low miR-192 levels were signiifcantly associated with lymph node (P=0.021) and distant metastasis (P=0.023). An inverse relationship between miR-192 and ZEB2 protein expression was identified in CRC group (r=-0.365, P<0.05). Conclusion: MiR-192 downexpression was correlated with CRC metastasis. MiR-192 may play a role in the development and progression of CRC through ZEB2.
2.A pathogenesis study of tic disorder in children based on pathogen incubation theory
Journal of Integrative Medicine 2007;5(6):612-5
Pathogen incubation theory includes "no manifestation after infection" and "manifestation after incubation". Clinical data showed that the incidence and recurrence of tic disorders in children had a strong relevance to six exogenous factors. The pathogenesis is similar to the pathogenic mechanism based on incubation of pathogen theory, so we proposed a theory of "tic disorder induced by incubation of pathogen". Pathogenic wind can be classified into exterior wind and endogenous wind. Pathogenic wind is more apt to move, rise and migrate. The characteristics of pathogenic wind, especially easy mobility, determine the symptoms and signs of tic disorder, for pathogenic wind can be characterized by vibration and involuntary movement such as convulsion and tremor. If exogenous pathogenic wind moves into half-exterior and half-interior phase from the exterior, both the exterior and interior syndromes should be treated at the same time. We should regulate the function of the liver and the lung, expel pathogenic wind by dispersing the lung, and calm endogenous wind by removing obstruction in the collaterals and soothing the liver.
3.The expression and significance of high mobility group protein box1 in ovarian endometriosis tissue
Journal of Chinese Physician 2013;15(10):1349-1352
Objective To investigate the expression of high mobility group protein box1 (HMGB1)in ovarian endometriosis tissue and to provide new idea for early diagnosis,treatment and prognosis of endometriosis.Methods The levels of HMGB1 in ectopic endometrium and eutopic endometrium of 69 patients with ovarian endometriosis and endometrium of 69 cases with non-endometrioses were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western-blotting.Results HMGB1 was expressed in all the three groups (ectopic endometrium eutopic endometrium endometrium with non-endometrioses).The relative expression level of HMGB1 mRNA was 0.54383 ± 0.0565,0.3016 ± 0.0614,and 0.1536 ±0.0444,respectively (F =377.923,P < 0.0001).The relative of HMGB1 protein was 0.83990 ±0.12869,0.40100 ±0.16425,and 0.19986 ± 0.08162,respectively (F =185.625,P =0.0000).The expression level of HMGB1 was related to clinical stages (t =10.28,P <0.01) ; however,it was not obviously related to age,the diameter of lump,and course of disease (P > 0.05).Conclusions Over expression of HMGB1 in ovary endometriosis indicates that HMGB1 plays a significant role in occurrence and development of ovary endometriosis.The expression of HMGB1 in endometriosis eutopic endometrium was much higher than that of non-endometrioses endometrium,which supports the eutopic endometrium determinism.The overexpression of HMGB1 was consistent with clinical stage,which proves that HMGB1 maybe be tightly associated with the severity of the disease and to likely become biomarker.

5.Research advances in detection and clinical significance of circulating HPV DNA in patients with cervical cancer
China Oncology 2001;0(02):-
Recently,much interest has been focused on the clinical application and biology of tumor-derived DNA in the plasma/serum of cancer patients.Such interest has resulted in the demonstration of human papillomavirus(HPV) DNA in the plasma/serum of patients with cervical cancer(CC).The studies used different materials(plasma /serum),different DNA extraction methods and different primers to detect circulating free HPV DNA,so the positive rates varied from(6.9%) to 50%.The HPV DNA in the plasma/serum of patients suffering from CC most likely originates from the tumor itself,which will probably provide us with a new tool for CC monitoring after primary treatment,especially in patients in advanced stages.It is expected that this promising molecular tumor marker would soon be put into routine clinical use.

10.Expressions of ubiquitin and apotosis-related protein in diabetic rat brain
Chinese Journal of Geriatrics 2010;29(8):686-690
Objective To explore the effect of continuous hyperglycemia on learning and memory capacity in rats, and to observe the changes of expressions of ubiquitin and apotosis-related proteins, so as to provide a relative basis for diabetic encephalopathy. Methods The male SD rats were randomly divided into normal control group and diabetes mellitus (DM) group. The DM rats was made by intraperitoneal injection of streptozocin (STZ). The capacities of learning and memory were tested by Y-maze. The structure changes in frontal lobe cortex and hippocampus were observed by Nissl's staining and immunohistochemistry. The apoptosis cell count was measured by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). The expressions of Bcl-2 and P53 were assessed by Western-blot analysis. The expression of ubiquitin mRNA was detected by reverse transcription-polymerase chain reaction (RT-PCR). Results In DM rats, the learning and memory capacities were worse than in control rats (P<0. 05), and the apoptosis cell counts in frontal lobe cortex and hippocampus were higher than in control rats, the expression of Bcl-2 gene was reduced while the expressions of ubiquitin and P53 gene were increased (P<0. 05). Conclusions In the frontal lobe cortex and hippocampus, the expression of Bcl-2 gene is reduced while the apoptosis cell numbers and ubiquitin P53 gene expression are increased, which may contribute to neurodegeneration in DM rats.
