Through PubMed, CNKI and other databases to retrieve original documents about the maintenance treatment of advanced colorectal cancer, collect and analyzed research theory and progress in the maintenance treatment of advanced colorectal cancer. The clinical efficacy of maintenance therapy are evaluated and the patient's disease-free survival and quality of life are observed. The Result shows that the maintenance treatment can improve disease-free survival of advanced colorectal cancer patients, and the toxicity of maintenance treatment can still be tolerated. So the maintenance treatment of advanced colorectal cancer has better clinical efficacy, it is worth to study in the future.

AIM:To compare the accuracy of conventional contact A-scan and IOL Master in measuring axial length and anterior chamber depth, and to evaluate the characteristics of these two different methods.METHODS:Totally 145 cases (189 eyes) who underwent phacoemulsification and intraocular lens implantation in our hospital from January 2015 to December 2016 were observed prospectively.They were divided into five groups according to ocular axial length measured by IOL Master(Group A:AL≤22mm, Group B:22mm28mm).The axial length and anterior chamber depth were measured by A-scan and IOL Master respectively before operation, corneal curvature was measured by IOL Master.AL≤22mm using Hoffer Q formula to calculate the crystal degree, AL>22mm using Haigis formula to calculate the crystal degree.Analysis of axial length, anterior chamber depth and mean absolute refractive error at 3mo after surgery.RESULTS:The axial length measured by A-scan and IOL-master:Group A were 21.48±0.41mm and 21.46±0.40mm (P>0.05);Group B were 23.13±0.62mm and 23.14±0.63mm(P>0.05);Group C were 25.24±0.56mm and 25.27±0.59mm(P>0.05);Group D were 26.97±0.59mm and 27.03±0.64mm(P>0.05);Group E were 30.76±1.40mm and 31.01±1.53mm(P<0.05).Mean absolute refractive error (MAE) at 3mo after surgery by A-scan and IOL Master:Group A were 0.50±0.30D and 0.43±0.27D(P>0.05);Group B were 0.48±0.34D and 0.45±0.32D(P>0.05);Group C were 0.56±0.32D and 0.49±0.40D(P>0.05);Group D were 0.64±0.16D and 0.50±0.22D(P>0.05);Group E were 0.91±0.47D and 0.62±0.29D(P<0.05), MAE≤±0.50D were 38.7% and 65%(P<0.05), MAE≤±1.00D were 69.2% and 83.3%(P>0.05).Anterior chamber depth measured by A-scan and IOL Master:Group A were 2.81±0.35mm and 2.82±0.41mm (P>0.05);Group B were 3.04±0.50mm and3.10±0.47mm (P>0.05);Group C were 3.55±0.62mm and 3.60±0.52mm (P>0.05);Group D were 3.42±0.24mm and 3.51±0.30mm(P>0.05);Group E were 3.50±0.28mm and 3.61±0.34mm(P>0.05).CONCLUSION:IOL Master and contact A-scan have a high degree of consistency in the biological measurement, IOL Master has higher accuracy for patients with high myopia and long axis.It is a simple, accurate, good-repeatable and non-contact measurement tool.

Objective To explore the natural forgetters' episode memory and personality characteristics.Methods Situational Self-Awareness Scale(SSAS),Russell Loneliness Scale and Zimbardo Time Perspective Inventory(ZTPI)are used upon 127 natural forgetters and subjects of control group.in which 90 subjects participate tions,natural forgetters performance worse than subjects of control group(t=1.76 one-tail,P＜0.05),but subjects getters score lower in the SSAS and the future subscale of ZTPI(t1=1.73,P＜0.05 one-tail;t 2=2.70,P＜0.05),and tend to endorse in the present fatalistic subscale of ZTPI(t=2.19,P＜0.05),but don't feel more lonely.Conclusion Natural forgetters episodic memory is selectively micro-injured under the enactment conditions,which is different from the aging impairment mode of selective source memory,and they have some special personality characteristics.

Objective To develop an HPLC method for the simultaneous determination of 7-ethyl-10-hydroxycamptothecin-10-palmitic acid ester(SN38-PA)and its active metabolite 7-ethyl-10-hydroxycamptothecin(SN38)in rat plasma. Methods The inter standard was 10-hydroxycamptothecin. The protein in plasma was precipitated with methanol after acidification with formic acid. SN38-PA and SN38 were separated on Agilent C18 column(4.6 mm×250 mm,5μm) with gradient elution by using the mobile phase of methanol-0.2% formic acid solution. The flow rate was 1 ml/min. The detection wavelength was set at 372 nm. The column temperature was maintained at 30℃. Results The linear ranges for SN38-PA and SN38 were 0.25-62.5(r=0.9998) and 0.05-12.5 μg/ml (r=0.9997) respectively. The limits of quantification were 0.18 and 0.04 μg/ml, respectively. The average relative recovery of SN38-PA and SN38 were 95.89% and 97.03%. The average absolutely recovery of SN38-PA and SN38 were 99.54% and 99.84%. The RSD for intra-day and inter-day were both less than 3%. Conclusion The method is fast, convenient, accurate and sensitive, so it can be used for determination of SN38-PA and SN38 in vivo.

Objective To investigate the interrelationship between Golgi phosphoprotein 3 ( GOLPH3 ) expression with vasculoar endothelial growth factor( VEGF) expression in the progression of human gastric cancer by detecting the expression level of GOLPH3 and VEGF. Methods Immunohistochemistry ( IHC) was used to detect the ex-pression of GOLPH3 and VEGF in 55 cases of gastric cancerous and carcinoma-adjacent tissues. Pearson correlation analysis was used to discuss the association between GOLPH3 expression with VEGF expression. Results The im-munohistochemical detection showed that the positive expression rates of GOLPH3 and VEGF were 67. 27%, 58. 18% respectively, which were significantly higher than the positive expression rates in carcinoma-adjacent tis-sues ( P<0. 05 ) . A statistical analysis revealed that the positive expression rate of GOLPH3 and VEGF in the gas-tric cancer tissues were strongly correlated with depth of invasion ( P<0. 05 ) , distant metastasis ( P<0. 01 ) and TNM stages (P<0. 01), whereas it did not significantly correlate with age or gender or size of tumor. Compared with the negative for the GOLPH3 expression, the VEGF expression in gastric cancer tissues positive for the GOL-PH3 expression was significantly higher. The protein level of GOLPH3 expression was positively correlated with VEGF expression (r=0. 508,P<0. 01). Conclusion GOLPH3 overexpression may regulate gastric angiogenesis by upregulating the expression of VEGF, which affects the invasion and metastasis of gastric cancer.

Objectives To study the relationship between TCM syndromes and adiponectin (APN) level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis, and provide evidence for clinical diagnosis and treatment. Methods One hundred patients of hypertension complicated with carotid atherosclerosis were divided into phlegm syndrome group, stasis syndrome group, and intermingled phlegm and blood stasis syndrome group, and compared with 30 healthy people as control. Carotid atherosclerosis plaque was detected with GE LOGIQ500 color ultrasound system. ELISA was used to determine the serum APN. Results APN of the intermingled phlegm and blood stasis syndrome group was obviously lower than other groups, and there were obvious differences among them. There were more plaques in the intermingled phlegm and blood stasis syndrome group. A negative correlationship was showed between carotid artery intima media thickness (IMT) and APN of hypertension complicated with carotid atherosclerosis. Conclusion There is correlation between TCM syndrome and APN level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis. The anomalous change of APN and plaque formation of the patients can be preliminarily estimated with the syndrome of TCM.
