One treatment course(after 30d) observation curative effect.[Results]The western medicine control group 15 cases cured, 6 cases were markedly effective, 6 cases better, 3 had no effect, the total effective rate was 90%. Traditional Chinese medicine control group 21 cases cured, 6 cases had marked effect, improvement in 3 cases, the total effective rate was 100%. Treatment group: 24 cases were cured, 3 cases had marked effect, improvement in 3 cases, the total effective rate was 100%.[Conclusions]Three treatments had curative effect, but the side effects of western medicine stopped taking the drug repeatedly; for the special athletes, the acupuncture treatment is worthy of popularization and application.

Objective To investigate the influence of laparoscopic resection of colorectal cancer on (postoperative) micrometastasis of tumor cells.Methods Using cytokeratin,CK-20 mRNA as target gene,the RT-PCR method was used to examine the pre-and post-operative changes in the number of tumor cells in the peripheral blood of 48 cases of colorectal cancer.Results After operation,the number of tumor cells in(peripheral) blood was significantly higher in the laparoscopic surgery group as compared to that of traditional(laparotomy) operation group(P0.05),but was significantly related to positive rate of proliferating cell nuclear antigen(PCNA)(P

Tyrosine kinase receptors mediate many critical cellular functions that contribute to tumor progression and metastasis.Recepteur d'origine nantais(RON)belongs to a subfamily of receptor tyrosine kinases(RTK)with unique expression patterns and biological activities.RON is activated by a serum-derived growth factor macrophage stimulating protein(MSP),primarily expressed in cells of epithelial origin.RON activation induced cell transformation,growth,migration and matrix invasion.We review RON molecular structure,activation,and carcinogenic mechanism related.It will contribute to cancel treatment and to discuss RON expression in the tumor.

Objective To analyze the discourse right construction of China’s medical aid to Africa,so as to provide evidenc?es for improving the effect and sustainable development of China’s medical aid to Africa. Methods The documents of the dis?course right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects,namely confident,charismatic,influential,and dominant. Re?sults China’s medical team made much in the discourse right construction in their aid to Africa,but some China’s medical team members were still too cautious and too low?key. China’s medical team gained the trust of the people of Africa,but the lan?guage communication difficulties still hampered in China’s medical aid to Africa. Chinese medical team were widely praised by the African society,but in the west,some African media,even China’s media still neglected to report China’s doctors. China’s international discourse right were greatly improved,but western countries still dominated the public opinion. Conclusion Chi?na should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

Objective Carboxypeptidase E ( CPE) is one of the most important carboxypeptidases in-volved in the biosynthesis of numerous peptide hormones and neurotransmitters and plays an important role in en -docrine regulation .A splice variant of CPE ( CPE-ΔN) has been detected and the mechanism of CPE -ΔN action in tumorigenesis has been studied in many different cancers .The aim of this study is to examine CPE -ΔN ex-pression in human colorectal cancer ( CRC) and to evaluate its possible application as a potential prognostic mark-er.Methods In the present study ,we have analyzed isoform expression of CPE -ΔN by qRT-PCR and West-ern blot in 219 CRC patients .Results Our results showed that CPE -ΔN was overexpressed in colorectal tumor tissue and that high CPE -ΔN mRNA expression was closely correlated with tumor differentiation ,pT classifica-tion,pN classification,tumor recurrence and lymph node metastasis .High CPE-ΔN expression was also identi-fied as an independent prognostic factor using a multivariate analysis (P=0.011).Conclusion Based on these results,we can conclude that CPE -ΔN expression might be a potential prognostic marker for CRC patients .

Objective To detect the TNFSF13 expression and to evaluate its possible use as a potential prognostic marker in breast cancer .Methods We analyzed TNFSF13 expression by Western blot and qRT -PCR in 93 breast cancer patients .Results Our results showed that TNFSF 13 was overexpressed in breast cancer tis-sue.High TNFSF13 mRNA expression was closely correlated with tumor differentiation , pN classification ( P=0.003,0.022).In addition,patients with high TNFSF13 expression had a significantly shorter survival analyzed by Kaplan-Meier(P=0.04,log-rank test).Cox proportional hazards regression multivariable analysis revealed that high expression of TNFSF13 was identified as an independent prognostic factor (P=0.03).Conclusion TNFSF13 expression might be a novel target for prognosis and intensive therapy in breast cancer patients .

Objective To develop a fast shimming method for permanent magnet MRI system. Methods Peak location method (PLM) was improved by calculating the eddy current effect, and the time deviation was replaced by their phase to increase the precision. Results Experiment showed that the new method took less than 45 s, which was 3 times faster than conventional method while providing the same homogeneity. The result of PLM satisfied the requirement of homogeneity. Conclusion This new method can significantly improve the homogeneity in a short time and satisfy further fast pulse sequence development on 0.5T permanent magnet MRI system, which can be generalized for any permanent magnet first order shimming.

Aim To investigate the toxicity of isopsor-alen in HepG2 cells and its effects on bile acid, bile acid synthesis and transport. Methods Cell viability was evaluated by MTT assay and bile acid was deter-mined inside HepG2 cells, with exposure to various isopsoralen for 24h. The mRNA transcription of BSEP, MRP2, MRP3, NTCP, OATP2, OSTα, CYP7A1, CYP27 A1 , FXR and PXR were assessed by real-time PCR. Results The cell viability was decreased dose-dependently with isopsoralen in HepG2 cells, and IC50 was 118. 1μmol·L-1 exposure to isopsoralen for 24h. Bile acid inside cells significantly increased with 100 and 400 μmol · L-1 isopsoralen. Isopsoralen caused the down-regulation of MRP2 , MRP3 , CYP7 A1 mRNA at 25 μmol · L-1 . Beside these, the up-regulation of OATP2,OSTα,CYP27A1,FXR,PXR with 100 μmol· L-1 isopsoralen, but there was no significant change of BSEP and NTCP. Conclusion The results show that isopsoralen induces bile acid accumulation and cytotox-icity which may be associated with the down-regulation of MRP2, MRP3 in HepG2 cells.
