CMTM3 and CMTM7 are two newly discovered anti-oncogenes,which exist in various kinds of organs and tissues and having multiple biological functions including cell proliferation,differentiation,migration,and apoptosis. Recently,it has been shown that these two anti-oncogenes have closely relationship with gastrointestinal tract tumor,which can inhibit the growth of esophageal,gastric,and colorectal cancer. In this review article,the advances in study of the relationship between these two anti-oncogenes and tumors of gastrointestinal tract were summarized.

Cardiovascular disease is a severe threat to human health and life. Among many risk factors of cardiovascular disease, genetic or gene-based ones are drawing more and more attention in recent years. Accumulated evidence has demonstrated that the loss or mutation of ataxia telangiectasia mutated (ATM) gene can result in DNA damage repair dysfunctions, telomere shortening, decreased antioxidant capacity, insulin resistance, increased lipid levels, etc., and thus can promote the occurrence of cardiovascular risk factors, such as aging, atherosclerosis and metabolic syndrome. In this review, we discusses the possible mechanisms between ATM gene and cardiovascular risk factors, which could be helpful to the related research and clinical application.

The low mass cutoff ( LMCO) is the main weakness of ion trap when it performs tandem mass analysis by collision induced dissociation (CID). LMCO means that some daughter ions of m/ z are less than about 1 / 3 of the m/ z of parent ion could not be detected during the tandem mass spectrometry processing. A new method which can significantly improve the effect of low mass cutoff was proposed and investigated. By simply changing the scan method of digital potential frequency, some low mass ions can be effectively observed during the tandem mass spectrometric experiment. In the experiment, the frequency of the digital ion trapping power and ion activation power were scanned from lower value to higher value, and some lower mass product ions could be detected during CID process. For example, some lower mass ions were observed during the CID of reserpine precursor ion when the frequency of its digital trapping power was scanned from 500 kHz to 560 kHz. The tandem mass spectra of Reserpine ion showed that the experimental results both from this work and the triple quadrupole mass spectrometer were exactly the same.

Seven compounds were isolated from the alcohol extract of leaves of Ipomoea batafas Lam,by column chromatography on silica gel. They were identified by physical and chemical methods as quercetin-3-glucoside (Ⅰ), kaempferol-4＇, 7-dimethyl ether(Ⅱ), ombuin (Ⅲ),quercetin (Ⅳ), quercetin-3＇, 4＇, 7-trimethyl ether(Ⅴ), ?-sitosterol (Ⅵ) and sucrose (Ⅶ).All of them were isolated from this plant for the first time.

Objective:To investigate the effects of bFGF on the proliferation of human salivary adenoid cystic carcinoma cell ACC-2 in vitro. Methods:The effect of bFGF on proliferation of ACC-2 cell line was observed by MTT assay; ERK activity was measured by immuno-precipitation; and ERK and I-?B? expressions were assessed by Western blot. Results:bFGF can enhance the proliferation of ACC-2 cell line. Stimulated by bFGF, the proliferation ratio increased significantly. The intracellular ERK activity and p-ERK expression were increased and I-?B? expression was inhibited by different concentrations of bFGF. The above effects of bFGF can be attenuated by MEK inhibitor U0126. Conclusion:bFGF stimulates the proliferation of ACC-2 in the dose dependent manner, which may be due to up-regulating ERK, NF-?B signaling pathway.

0.05 ).The detection rate of IRC by B-ultrasound accounted for 98.2%(108/110).The rate of surgical excision in IRC was 92.2%(107/116).Stage Ⅰ to Ⅱ lesions were found in 69.0% of the patients with IRC and in 49.3% with CRC.Stage Ⅲ to Ⅳ lesions were found in 31.0% of the patients with IRC and in 50.7% with CRC.Patients were followed up postoperatively for a mean of (45?40) months.The 3- and 5-year cancer specific survival rates were significantly higher in IRC than those in CRC (86.5% and 81.3% vs 70.8 % and 64.2%, P

The factor of antiapoptosis in cancer is recently identified as survivin. Survivin is prominently overexpressed in embryonic and fetal tissues, and various human cancers. It is potentially involved in both inhibition of apoptosis and control of cell division. Recently, survivin is found to be correlated with the genesis, progress, and prognosis of urological cancer. Manipulation of the antiapoptotic pathway maintained by survivin may be beneficial for cancer therapy. Progressive research of survivin in urological cancer.

Objective To evaluate the clinical application of GlideScope~ video laryngoscope in anesthetic endotracheal intubation.Methods Two hundred patients who received surgery under general anesthesia with ASA I or II were involved in this study.One hundred patients were assigned to be intubated with GlideScope~(GS group) and the other 100 with size 3 Macintosh laryngoscope(ML group).The following data were recorded and analyzed: noninvasive blood pressure(NBP),heart rate(HR) at the different time points of intubation process,glottic exposure time,CormarkLehane grade,tracheal intubation time and total intubation attempts.
