Inhibitor of DNA binding 1 (ID1) has an aberrantly high expression in multiple cancer tissues, including colon cancer, lung cancer, breast cancer, and so on, which is closely related to cancer aggressiveness and poor clinical outcomes in cancer patients. It has been reported that ID1 maintains colorectal cancer cells (CRCs) stemness traits and contributes to the CRC drug resistance. While, the biological molecular mechanisms have not been fully elucidated. In this research, we found that ID1 upregulates octamer binding transcription factor (OCT4) protein level as well as OCT4 signaling pathway via Western blot, gene set enrichment analysis (GSEA), dual-luciferase reporter assay, and real-time PCR. Through the in vitro sphere formation assay, we found that overexpression of OCT4 reverses the inhibitory effect of knocking down ID1 on CRC sphere formation ability. With the help of JASPAR and GEPIA database, we predicted a novel transcriptional repressor—forkhead box D3 (FOXD3) of OCT4. Finally, by using co-immunoprecipitation (Co-IP), confocal and real-time PCR, we demonstrated that ID1 interacts with FOXD3 to inhibit its transcriptional repression activity and therefore to upregulate OCT4 transcription and OCT4 signaling pathway. In conclusion, this study provides a new theoretical basis for the regulation mechanism of colon cancer stem cells, and the newly found protein-protein interaction of ID1-FOXD3 provides a potential drug target for the therapy of CRC.

Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P＜0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.

In order to improve the efficiency of drug screening on serotonin transporter (SERT) inhibitors, a high-throughput screening (HTS) model is established in RBL-2H3 cells. The RBL-2H3 cells are very similar to the serotonin genetic neuro, in modulation of post-receptor mechanisms and transduction pathway of SERT reactivated. Depending on a fluorescence substrate ASP+ used in detection method of inhibitor rates, it's convenient, quick, accurate and effective, not making the environmental biohazard compared with radioactive experiments. Furthermore, biological screening model combined with computer aided virtual screening technique describing high-throughput virtual screening (HTVS). Bayesian classification method and molecular fingerprint similarity were applied to virtual screening technique, for screening compounds in compound library. Some compounds have been found, and then validated further by biological screening model. Combination of HTS and HTVS improves the efficiency of screening SERT inhibitors.

BACKGROUND: At present, there is few reports about using middl ecerebral artery obstraction (MCAO) model to determine the repair course of cerebral infarction during functional training.OBJECTIVE: To determine the effect of electro-stimulating therapy on promoting the rehabilitation of cerebral infarction and its mechanism.DESIGN: Randomized controlled study.SETTING: Animal Center and Electron Microscope Laboratory of Zhongshan University.MATERIALS: The experiment was carried out in the Animal Center of Zhongshan Medical College and Neurological Laboratory of the First Affiliated Hospital of Zhongshang University from January 2002 to December2004. A total of 200 healthy males SD rats, aged 3 months and weighing 90-110 g, were selected. According to the following criteria: SBP＞180mmHg (1 mmHg=0.133 kPa), BWT score of MCAO models which were reproduced by RHRSP was 1, totally 180 RHRSP were admitted to the research and divided into electro-stimulating therapy group (n=90) and control group (n=90).METHODS: Electro-stimulating was given to four accupuncture points of the paralyzed limbs of rats. The electro-stimulating treatment was given about 30 minutes once a day. And a therapy course was 6 days, and between two therapy courses there was one-day break. At the end of 1st, 3rd,6th and 9th therapy courses, the brain of motor function and tissue in marginal zone of cerebral infarction were assayed as follow: [1] The beam walking test (BWT, 1 as severe disorder and 7 as normal). [2] Electron microscope. [3] Astrpcyte glial fibriliary acidic protein, neurofilament protein and microtubule-associated protein-2 were assayed with immunohistochemistry. Five fields of each slice in the two groups were randomly selected to add up the positive cell number. Totally 30 positive cells of glial fibriliary acidic protein was selected to assay average absorbency (A) of positive cellular plasm. [4] Apoptosis of neurons were observed with in situ end-labeling (ISEL). [5] Brain-micro vasodilatatio was observed according to the criteria of one complete microvessel account under the field.MAIN OUTCOME MEASURES: [1] Scores of motor function; [2] Ultramicrostructure of cranial neurons and astrocyte; [3] Cranial glial fibriliary acidic protein, neurofilament protein and microtubule-associated protein-2;[4] Apoptosis of neurons; [5] Diastole of cerebral microvessel.RESULTS: Totally 180 rats were eligible while 20 rats were excluded because of their BWT score＞1 after MCAO operation. [1] Results of beam walking test (BWT): Functional recovery of paralysis limbs in electric stimulation group was better than that in control group from the third to the ninth course. In the ninth course, 6 points of rats in electric stimulation group was more than that in control group (42, 46, χ2=15.4, P ＜ 0.01). [2]Positive absorbency of cerebral glial fibriliary acidic protein: That in electric stimulation group was higher than that in control group in the 3rd, 6th,and 9th [(52.97±0.59)% vs (46.40±0.56)%; (49.44±0.80)% vs (46.40±0.56)%;(43.25±0.48)% vs (34.20±0.50)%, P ＜ 0.05]. [3] Assay of neurofilament protein: That in electric stimulation group was higher than that in control group in the 6th and 9th course [(22.9±2.7)% vs (11.9±2.3)%; (26.5±1.7)%vs (11.7±1.5)%, P ＜ 0.05]. [4] Assay of microtubule-associated protein-2:That in electric stimulation group was higher than that in control group in the 6th and 9th course [(21.7±1.3)% vs (11.3±1.1)%; (24.4±2.1)% vs(11.9±2.3)%, P ＜ 0.05]. [5] Apoptosis of neurons: There was not significantly different between the two groups. [6] Results of open number of cerebral microvessel: That in electric stimulation group was higher than that in control group in the 1st, 3rd, 6th and 9th course (33 vs 19; 48 vs 31;45 vs 25; 46 vs 23, Z=-2.309, P ＜ 0.05).CONCLUSION: Electro-stimulating treatment can promote motor function of paralyzed limbs, which was due to that electro-stimulating treatment may promote extinction of the swollen feet of astrocytes, reinforce neurons activity and arouse the dilatation of cerebral capillary which promote the microvascular dilatation in order to improve cerebral blood circulation.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

Objective To explore the relationship between blood lipids level with creatinine clearance rate(Ccr)in patients with heart failure(HF). Methods A total of 955 patients who were diagnosed with heart failure(cardiac function NYHAⅡ~Ⅳclassification)upon discharge from the Department of Cardiology of the Second Hospital of Tianjin Medical University, between January 2010 to June 2013 were enrolled as HF group. Healthy adults (n=200) with normal cardiac function which approximately matched basic condition with HF group were selected as control group. The HF group was fur?ther divided intoⅡ,Ⅲ,Ⅳclassification according to their cardiac function(NYHA classification). HF group was also divid?ed into normal renal function group, mild renal injury group and moderate-severe renal injury group based on their Ccr. Ef?fect of gender and lipid parameters were also compared. Binary logistic regression was used to analyze factors influencing renal function in patients with HF. Results Compared with people in the control group, the levels of triacylglycerol(TG), total cholesterol(TC), low density lipoprotein cholesterol(LDL-c)and non high density lipoprotein cholesterol(non-HDL-c)in patients of HF group were increased while Ccr and high density lipoprotein cholesterol(HDL-c)were decreased. Ccr and lipids were obviously decreased in patients with HF of Ⅳclassification. TG and HDL-c were decreased in moderate-severe renal injury group. Females had a higher lipid levels than males in HF group(P<0.05 or P<0.01). Advanced age, coronary heart disease and hypertension were all risk factors for renal impairment in patients with HF by binary logistic re?gression. On the other hand, weight gain and HDL-c were the protection factors for renal function in HF patients. Conclu?sion Dyslipidemias may lead to renal insufficiency in patients with HF. It was important to control lipids and improve re?nal function in patients with HF.
