To introduce professor YAN De-xin's experience in diffrerentiating and treating Emeda with Heart Involved from qi and flood He thinks that pathogenesis of Emeda with Heart Involved is water overflowing due to yang deficiency,internal retention of blood stasis and turbidity.So this disease can be differentiated from these aspects including the disturbance of the functional activities of the lung,failure to transform body fluid;body fluid transformed by blood stasis,simultaneous disorders of both blood and body fluid;deficiency of pectoral qi,derangement of qi and blood.What's more,he proposes the application of drugs for warming yang and promoting blood circulation is very important.

AIM: To analyze the clinical value of femtosecond laser in vitrectomy combined with phacoemulsification and intraocular lens (IOL) implantation.
METHODS: We selected 100 patients ( 102 eyes ) undergoing vitrectomy combined with phacoemulsification and IOL implantation in our hospital from October 31 2013 to October 31 2015. They were divided into routine operation group, 50 cases (52 eyes), and femtosecond laser group, 50 cases (50 eyes). The parameters were compared between the two groups, including total operation time, postoperative complications ( elevated intraocular pressure, uveitis, vitreous hemorrhage, and retinal detachment ), postoperative intraocular pressure and postoperative half of the visual acuity ( near visual acuity, visual acuity, uncorrected visual acuity, corrected visual acuity).
RESULTS: The difference on total operation time of the two groups was statistically significant ( P < 0. 05). The differences between the two groups on postoperative intraocular pressure, uveitis, vitreous hemorrhage, retinal detachment were not statistically significant ( P >0. 05). There were no significant differences on internal pressure, near visual acuity, far visual acuity, uncorrected visual acuity, corrected visual acuity at 6mo after surgery (P>0. 05).
CONCLUSION: Femtosecond laser in vitrectomy combined with phacoemulsification and IOL implantation has a high safety and efficacy with the advantages as accurate, efficient.

BACKGROUND: Colorectal cancer is a common malignant tumor in digestive tract. Theory of tumor stem cells (TSCs) offers a new approach to understand the development mechanism of colorectal cancer. OBJECTIVE: To review the progress in the existence, origin and identification of colorectal cancer stem cells (Co-CSCs). RETRIEVAL STRATEGY: Pubmed was undertaken to identify relevant articles published from January 1990 to July 2007 with the of "colorectal cancer,stem cell,tumor stem cells" in English.At the same time, Vip database was undertaken to identify the relevant articles published between January 1990 and July 2007 with the key words of "colorectal cancer, stem cell, tumor stem cells" in Chinese. The data were selected primarily, and then quotations of each article were checked. Inclusive criterion: the articles related to the advances of the existence, origin and identification of Co-CSCs were selected. Exclusive criterion: the articles with repetitive research were excluded. Totally 63 relevant articles were selected and 33 of them met the inclusive criterion. The 30 excluded articles were of old or repetitive content. LITERATURE EVALUATION: Of the 33 inclusive articles, 28 were on the existence and origin of Co-CSCs, 4 were about the isolation and identification of Co-CSCs, and 1 was about the problems and prospect. DATA SYNTHESIS: TSCs is a rare population of cells in tumor tissues with infinitely proliferative and self-renewal potential that drive the formation and growth of tumors. It may become a new target to eradicate malignant tumor. TSCs have been discovered in leukemia and some solid tumors. Intestine stem cells are poorly differentiated. Its phenotype is difficult to identify. There are many reports on the quantity, location, origin, function and relation with intestinal disease. Co-CSCs have been isolated and identified as EpCAMhigh/CD44+ cells recently, which accelerate to understand the mechanism of colorectal cancer. CONCLUSION: The discovery of Co-CSCs is one of the advances in researching of malignant tumor. TSCs may become a new target to eradicate malignant tumor, and brings hope to cure it.

We studied the alteration of local and circulat-ing RAS during cardiac hypertrophy caused by ab-dominal aorta constriction (AC, with nephrectomyof left side) and aorta-vena fistula (AVF). Bothventricular and plasma angiotensin Ⅰ and Ⅱ (AngⅠ. Ⅱ), and plasma, renin actvity (RA) weremeasured by means of radioimmunoassay after twoand seven weeks of surgery. Despite the level ofplasma Ang Ⅰ, Ⅱ and RA were not enhanced, theventricular Ang Ⅰ and Ⅱ were increased signifi-cantly in AC rats (v. s. SO group P

BACKGROUND:Both local infiltration analgesia and femoral nerve block are used for the pain management after total knee arthroplasty. Controversy stil remains regarding the optimal technique for pain relief. OBJECTIVE:To systematical y evaluate analgesic effects of local infiltration analgesia and femoral nerve block after total knee arthroplasty. METHODS:Databases including PubMed, EMBASE, the Cochrane Library, Web of Science and CBM, were comprehensively searched to identify randomized control ed studies comparing local infiltration analgesia with femoral nerve block. Two reviewers independently selected trials, included literatures, extracted data, and assessed the methodological qualities of included studies according to Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0. When there were different opinions, it was decided by the third author. Data were analyzed by RevMan 5.3 software. RESULTS AND CONCLUSION:(1) Eleven randomized control ed trials involving 566 patients were included. (2) At 24 and 48 hours (h) after surgery, there were no significant differences between the local infiltration analgesia and femoral nerve block groups, in Visual Analog Scale scores [MD24 h=0.15, 95%CI (-0.26, 1.28), P>0.05;MD48 h=0.19, 95%CI (-0.06, 0.44), P>0.05] in the resting state, and [MD24 h=-0.01, 95%CI (-0.51, 0.48), P>0.05;MD48h=0.18, 95%CI (-0.45, 0.82), P>0.05] in the active state, amount of analgesic drug use [MD24 h=-2.23, 95%CI (-5.63, 1.16), P>0.05;MD48 h=2.44, 95%CI (-1.08, 5.95), P>0.05], hospital stay [MD=0.05, 95%CI (-0.40, 0.50), P>0.05], postoperative nausea and vomiting [OR=1.09, 95%CI (0.39, 3.04), P>0.05] and postoperative infection [OR=0.99, 95%CI (0.44, 2.59), P>0.05]. (3) These results indicated that the analgesic effect of local infiltration analgesia was identical to that of femoral nerve block after total knee arthroplasty. Due to its simple operation, local infiltration analgesia can be used as a standard analgesia method after total knee arthroplasty.

Objective: To clone the actin (ACT) gene of Eleutherococcus senticosus, and to make the gene a valuable internal gene. Methods: Part of the sequence of ACT gene was cloned by real-time PCR (RT-PCR), and the sequence was used as internal control gene for analyses of semiquantitative PCR and RT-PCR. Results: The ACT gene (1031 bp) of E. senticosus was cloned, coding 343 amino acids. To compare the amino acid sequence of E. senticosus ACT gene with those of Betula luminifera, Gossypium hirsutum, and Camellia sinensis, the amino acid homology was 99.42%, 98.83%, and 98.54%. The expression of ACT in different organs of E. senticosus during various growing periods was constant. The expression of ACT gene in different organs and during different growth and development stages was basically constant, and when the sequence acted as internal control gene, the semiquantative PCR and RT-PCR have good amplification effect and reproducibility. Conclusion: The ACT sequence in E. senticosus is firstly separated and reported, it could act as an internal control gene, and its reaction system of RT-PCR is established.
