The corresponding astronomy implications of yin-yang and five phases of traditional Chinese medicine are investigated based on the modern astronomy,universal biology,and literature research.It is found that the principles of yin-yang in traditional Chinese medicine actually refers to the strengths and the directions of gravitational forces,electromagnetic waves,high energy particle flows of celestial bodies to human.The yin-yang in the human body is a result of selective evolution from protobiont under the influence of yin-yang of celestial bodies in hundreds of millions of years.The revolution of seven luminaries,which includes the Sun,Moon,Mercury,Venus,Mars,Jupiter and Saturn,creates the day and night yin-yang from the self rotation of the Earth,season yin-yang from the revolution of the Earth around the Sun,the yin-yao from the rotation of the Moon around the Earth,and the yin-yao from the rotations of the Mars and the Jupiter.The 10 years cyclic movement of the Mercury displays the states of jiayi,bingding,wuji,gengxin,rengui,which have the allelopathic characteristics of five phases-wood,fire,earth,metal and water,respectively.With the addition of yin-yang from the Mars,the states of Mercury are divided into yang five phases including jia,bing,wu,geng and ren,and yin five phases including yi,ding,ji,xin and gui.The yin-yang and five phases of human visceras is the result of the selective evolution under the influence of yin-yang and five phases of celestial bodies in hundreds of millions of years.The 5 years periodic movement of the Venus shows the five phases characteristics of the five zhongyun.With the addition of the yin-yang from the Mars,every zhongyun shows the yin-yang characteristics,which alternate once every other year.In a cycle of sixty years,the Saturn,Mars,Venus,Mercury and Jupiter show 15 pairs of independent yin-yang states,which is corresponding to the 15 pairs of yin-yang nayin five phases.

Objective To study the effects of As_2O_3 on tumor model of hepatocarcinoma.Methods HepAgrafed hepatocarcinoma mouse model was established by subcutaneously injection of mouse hepatoma cells(1×10~6)into the oxter of mice.After treated by As_2O_3,the volume change of tumor and tumor inhibition rates were observed.The expression of vascular endothelial growth factor(VEGF) was detected by immunohistochemical and calculated the difference of MVD.Results The volume of tumor and the tumor inhibition rates were significantly decreased in As_2O_3 group compared with control group(P<0.05).The As_2O_3 could inhibit angiogenesis of xenograft tumor,depress expression of VEGF and decrease microvascular density(MVD).Conclusion As_2O_3 can inhibit the growth of tumor,inhibit the expression of VEGF and decrease MVD.

Objective To explore the role of OAZ gene in the pathogenesis of systemic lupus erythe-matosus (SLE) by using RNA interfering technique. Methods Peripheral blood mononuclear cells (PBMC) from SLE patients were collected. Each sample was equally divided into four groups for cell culture in 96 well plates. Specific siRNA for OAZ and GAPDH were concordantly added to the experimental group and the positive control group, while nonspecific siRNA was added to the negative control group and only culture medium was added to the Mock control group. Cells and supernatants were harvested after culturing for 72 hours, then RNA was extracted and reverse transcripted to cDNA. OAZ, Id1, Id2, Id3, Id4 mRNA expression levels were analyzed by using real-time PCR. Levels of IFN-γ, IL-4, IL-10, IL-12, IL-21, CCL2, ANA in the supernatant were tested by ELISA. Relationships between the expression levels of OAZ mRNA with levels of cytokines and ANA were analyzed. Results OAZ, Id1, Id2, Id3 gene mRNA expression levels (△Ct: 12.5±1.4, 8.9±1.5, 4.3±0.8, 8.04±1.1) in the experimental group were significantly decreased comparing to those in the negative control group (△Ct: 10.2±1.1, 6.5±1.2, 2.4±1.3, 6.2±1.2 respectively, P<0.05). Levels of IFN-γ, IL-10, IL-12, IL-21 and ANA in the experimental group were significantly lower than those in the negative control group (P< 0.05), but level of CCL2 was higher than the negative control group (P<0.05). Difference of OAZ mRNA expression levels (△△Ct) between the experimental group and the negative control group was negatively correlated with changes of ANA, IL-21 levels, but positively correlated with changes of Th1/Th2, CCL2. Conclusion OAZ siRNA can effectively reduce the expression of genes involved in the OAZ signaling pathway in SLE. OAZ may lead to abnormal production of ANA via regulating Id genes and cytokines.

Objective To establish a method of reverse hybridization to detect five subfamilies of low risk Human Papillomaviruses(HPV6,11,42,43 and 44)and eighteen subfamilies of high risk HPV (HPV16,18,31,33,35,39,45,51,52,53,56,58,59,66,68,73,83 and MM4)in one reaction.Methods Special probes for twenty-three HPV subfamilies were fixed on nylon membrane bars,biotin labeled general primers mediated polymerase chain reaction(GP-PCR)were applied in HPV DNA amplification.PCR amplified DNA fragments were reversely hybridized with special probes that were fixed on the membranes. All samples(136)detected by reverse hybridization method were paralleled with the methods of Hybridization Capture Ⅱ(HC-Ⅱ)and sequencing.Results Positive rate of the 136 samples detected by reverse hybridization was 41.9%,while HC-Ⅱ 42.6% and sequencing 40.4%.Reverse hybridization detection indicated coherence with the other two methods(Kappa 0.8644 and 0.9089,respectively).While sequencing was lab standard for DNA test,the sensitivity was 96.36%,specificity was 95.06%,accuracy was 95.59%.Conclusions Method of reverse hybridization is adaptable to 23 kinds of HPV subfamilies, which can confirm the exactly subfamilies of HPV infection.This method is adaptable in clinical detection of HPV,with high sensitivity,high specificity,simply and convenient operation and the results are easily to be read.

Objective To summarize the clinical experience of off-pump coronary artery bypass grafting (OPCABG) for treating high risk coronary artery disease (CAD,SinoSCORE ≥ 6 points),and to evaluate its safety and efficacy.Methods The clinical data of 73 patients with high risk coronary artery disease treated through OPCABG (high risk group)in our center from April 2012 to December 2015 were retrospectively analyzed and compared with those of other low or moderate risk 78 patients treated through OPCABG (SinoSCORE＜ 6 points,low or moderate risk group) at the same period.Results All operations in the high risk group were successfully performed.Compared with the low or moderate risk group,the rate of using left internal mammary artery grafts in the high risk group was reduced significantly (P＜0.05),the operation time,postoperative ventilator support time,postoperative intensive care unit stay time and postoperative hospitalization time were prolonged significantly (P＜0.05),the rate of using intraaortic balloon pump support was increased significantly (P＜0.05),and the occurrence rate of postoperative severe complications was also increased significantly (P＜0.05).Sixty-nine cases were postoperatively followed up for (18.3±8.6) months.During the following-up period,2 cases died.11 branches of internal mammary artery grafts patency (11/11) and 38 branches of great saphenous vein grafts patency (38/43) were confirmed in 18 cases by coronary artery computer tomography angiography or coronary angiography.One cases was performed the PCI therapy due to angina relapse,and other cases had no angina symptoms with good life quality.Conclusion OPCABG is a relatively minimally invasive and safe operative mode.Strengthening perioperative management can reduce the operation risk and achieves good short or middle term efficacy in the patients with high risk CAD.

AIM:To investigate the relationship between the expression of adducin 3 (ADD3) and its splicing isoforms and colorectal cancer (CRC).METHODS:The expression of ADD3, ADD3-Ia and ADD3-Ib in 50 pair of CRC tissues , 20 pairs of colorectal polyp tissues , and 2 CRC cell lines SW480 and SW620 before and after oxaliplatin or fluoroura-cil intervention were detected by real-time PCR.The cell activity was determined by MTT assay , the cell migration ability was evaluated by wound-healing assay , and the cell invasion ability was measured by Transwell assay .RESULTS:The expres-sion levels of ADD3 and ADD3-Ib were decreased in the CRC tissues as compared with the normal mucous (P<0.01), and ADD3-Ia/Ib ratio was increased in the CRC tissues (P<0.01).The expression level of ADD3-Ia was higher in T3-4 group than that in T1-2 group (P<0.05).Reduced expression of ADD3, ADD3-Ia and ADD3-Ib in colorectal polyps was observed compared with the normal tissues (P<0.01).Compared with the SW480 cells, the expression levels of ADD3-Ia and ADD3-Ib were lower (P<0.05) and the ADD3-Ia/Ib ratio was higher (P <0.01) in the SW620 cells.After treated with oxalipla-tin or fluorouracil, the cell activity, migration and invasion in the SW620 and SW480 cells were weakened accompanied by the increases in the expression levels of ADD 3, ADD3-Ia and ADD3-Ib to various certain extents .CONCLUSION:In CRC there is a tendency that ADD3-Ib reduction leads to ADD3 decrease, accompanied by an increased ADD3-Ia/Ib ratio.The expression changes of ADD 3 and its splicing isoforms in the CRC may be relevant to its invasion ability .

Objective To explore the best ratio of platelet-rich plasma (PRP) to activator and the synergistic action of thrombin and the growth factors in PRP gel on proliferation of human marrow-derived mesenchymal stem cells (hBMSCs). Methods The activator was made up of 1000 U bovine thrombin and 1 mL 10% calcium chloride solution. PRP was mixed with the activator at the ratios of 1:1, 5:1, 10:1, 20:1, 40:1 respectively in groups A, B, C, D and E. A quantitative sandwich enzyme-linked immunosorbent assay (ELISA) was used for examining the amounts of transforming growth factor-β1 (TGF-β1) and platelet derived growth factnr-AB (PDGF-AB) in PRP gel in each group after incubation for 0,1,8,24, and 120 hours. MTT assay was used to evaluate the effect of PRP gel in each group on hBMSCs proliferation. Results When PRP was mixed with thrombin, concentrations of PDGF-AB and TGF-β1 in PRP gel increased immediately and reached the peak value in 1 hour. The PRP gel in groups B, C, and D contained the highest amounts of PDGF-AB and TGF-β1, and accelerated hBMSCs growth re-markably. The cells proliferation in group A was inhibited. Conclusions The effect of PRP on the hBMSCs proliferation depends on the concentrations of PDGF-AB and TGF-β1 in PRP. Thrombin may influ-ence the hBMSCs proliferation by regulating concentrations of growth factors in PRP to certain extent, but too high a level of thrombin may inhibit hBMSCs growth.

Objective To investigate the effects of dilute concentration and acting time of pronase on quality of gastroscopy.Methods A total of 448 patients were randomly divided into two groups : sodium bicarbonate group and pronase with sodium bicarbonate group.Pronase was diluted into 50 ml (400 U/ml)and 100 ml (200 U/ml) using sodium bicarbonate.The patients were pretreated by pronase of different concentrations 10 min, 20 min, 30 min, 60 min and 120 min before gastroscopy.Diluent of same quantity were taken by the control group.Visibility of gastroscopy, procedure times and positive rates of lesions were compared.Results Pretreatment of pronase significantly improved visibility of gastroscopy, raised positive rates of lesions, and reduced procedure times of gastroscopy, compared with the control group (each P ＜ 0.05).The visibility of gastroscopy were over 80％ 20,30, and 60 minutes before the examination with no significant difference(P ＞ 0.05).The visibility of gastroscopy decreased sharply 30 minutes after taking pronase, especially after 60 minutes.There was no significant difference in the quality of gastroscopy between the 200 U/ml and 400 U/ml group 20-60 minutes before gastroscopy (P =0.640).Conclusion Pronase (200 U/ml-400 U/ml) significantly improves visibility of gastroscopy, raises positive detection rates of lesions, and reduces procedure time of gastroscopy 20-60 minutes before pretreatment.
