Objective To evaluate the feasibility and safety of embedding the totally implantable venous access port (TIVAP) via the access of right brachiocephalic vein (BCV).Methods The clinical data of 493 patients,who underwent the placement of TIVAP by using right BCV route during the period from March 2013 to December 2015,were retrospectively analyzed.The patients included 137 males and 356 females,with a mean age of (47.3±13.2) years old (ranging from 29 to 78 years old).The puncture success rate and TIVAP indwelling procedure-related complications were analyzed.Results The technical success rate was 100％,the success rate of initial puncturing was 99％ (488/493).The mean operation time was (22.5± 8.3) minutes (range of 18-35 minutes).Mis-puncturing of artery happened in 3 patients (0.61％,3/493);and no severe complications such as hemothorax or pneumothorax occurred.After implantation,the patients carried TIVAP for 124-986 days,with a mean of (271.1±53.8) days.The incidence of complications was 2.25％ (11/488),including hemorrhage at port site (n=2),catheter-related infection (n=l),partial thrombosis (n=2),and formation of fibrous protein sheath (n=6).No serious complications such as displacement or rupture of catheter,or catheter pinch-off syndrome (POS),etc.were observed.Conclusion The implantation of TIVAP by using right BCV route has high puncturing success rate,the technique is safe and reliable,and it can provide another option of catheter access for the clinical performance of TIVAP implantation.

Objective To explore the clinical value of guide-wire shaping in subclavian vein catheter-ization.Methods Totally 400 patients requiring right subclavian vein catheterization were equally divided into two groups according to the clinic date: intervention group ( with guide-wire shaping , n =200 ) and control group (without guide-wire shaping, n=200).The catheterization was carried out by the same doctor .The rates of ectopic wire were compared between the two groups .Results The overall success rate of catheteriza-tion was 98.25%(393/400) [98.5% (197/200) in intervention group and 98.0% (196/200) in control group, P=0.500].The incidence of catheter displacement was 1.02%(2/197) in intervention group, which was significantly lower than that [7.14% (14/196)] in control group (P=0.002).Conclusion As a sim-ple procedure , guide-wire shaping can effectively prevent catheter displacement during catheterization .

There are 250 species of Zanthoxylum (Rutaceae) in the world. This genus distributed in tropical and subtropical regions. Alkaloids are the major and representative ingredients in these plants including quinolines, isoquinolines, and amide alkaloids, with such biological activities as anti-tumor, anti-inflammatory, analgesic, anti-virus, anti-platelet aggregation, anti-bacteria and anti- oxidant. These species have been used for a long time to treat toothache, urinary and venereal diseases, lumbago and rheumatism. This review summarizes the chemical constituents and pharmacological activities from the Z. sppplants, in an effort to the systematic research and application of the alkaloids of this genus.

The meridians belong to zang-fu organs inside and connect with the extremities outside. They keep information exchange among different tissues and make various organs of the human body as an organic whole. If the meridians are blocked and the information exchange makes mistake, the body will produce pathologic changes. Because the location of the blocked part is difficult to identify, in this paper it is explained that selection of distal acupoints is the best way to dredge the nodes of disease, and the theoretical basis is closely related with the theories of "the root cause and symptoms of a disease", "Genjie", and "Jing, Xing, Shu, Jing, He", and also implies the thought of "to cure a disease must treat the root of the disease".

OBJECTIVE To explored the potential of pharmacological stabilization and reactivation of p53 for targeted cancer therapies. METHODS The cytotoxicity of a potent Cyclophilin A (CypA) inhibitor HL001 was tasted against a panel of cancer cell lines. The genotypes and activation of p53 were compared with the cytotoxicity profile of HL001. Two-dimensional (2D) PAGE analysis was performed to investigate differentially expressed proteins that involves in the anti-proliferation effects of HL001. Pull-down and Co-IP were used to confirmed the new identified PPI between CypA and G3BP1 and orthotopic animal model of lung cancer was used to tested the anti- tumor activity of HL001 in vivo. RESULTS We identify a novel CypA small molecule inhibitor HL001 that induces non-small cell lung cancer (NSCLC) cell cycle arrest and apoptosis via restoring p53 expression. We find that HL001 stabilizes p53 through inhibiting the MDM2-mediated p53 ubiquitination. Further mechanistic studies reveal that the downregulation of G3BP1 and the induction of reactive oxygen species and DNA damage by HL001 contribute to p53 stabilization. Surprisingly, HL001 selectively suppresses tumor growth in p53 wildtype NSCLC harboring Arg72 homozygous alleles (p53- 72R) through disrupting interaction between MDM2 and p53-72R in a CypA dependent manner. Moreover, combining HL001 with cisplatin synergistically enhance tumor regression in orthotopic NSCLC mouse model. CONCLUSION Pharma?cologic inhibition of CypA offers a potential therapeutic strategy via specific activation of p53-72R in NSCLC.

Objective To study the correlation between the coagulation factor Ⅶ (F Ⅶ) and progressive hemorrhage after brain contusion in mice and provide the experimental evidence for the clinical application of recombinant human FⅦa.Methods Twelve male BALB/c mice were given liposomeencapsulated FⅦsiRNA via tail vein at doses of 1,3,5 and 10 mg/kg with 3 mice per dosage.The other 3 mice received equivalent volume of normal saline as controls.Two days after the injection,mice blood sampling was used to detect FⅦ mRNA expression in liver using real-time PCR,level of plasma FⅦ using ELISA method,and activity of plasma FⅦ using chromogenic substrate assay.The optimal dose at which F Ⅶ expression was inhibited was determined.Thirty BALB/c male mice were assigned to two groups (n =15 per group) according to the random number table:FⅦ-suppressing group,mice were injected with FⅦsiRNA at the optimal dose and control group,mice were injected with same volume of negative control vector.The model of brain contusion was established in both groups.Volume of hemorrhage following brain contusion was measured at 3,24 and 72 h postinjury,and hematoma volume at 24 and 48 h postinjury.Results Liposome-encapsulated siRNA delivery down-regulated FⅦ expression in the mouse liver.Level and activity of plasma FⅦ were also reduced significantly.The optimal siRNA dose was 3 mg/kg.At 3,24 and 72 h postinjury,relative volume of brain hemorrhage in FⅦ-suppressing group was 1.46 ± 0.10,1.82 ± 0.23 and 2.28 ± 0.15 respectively,significantly higher than that in control group (1.00 ± 0.25,1.20 ± 0.31 and 1.20 ± 0.22 respectively) (P ＜ 0.05).At 24 and 48 h postinju-ry,volume of hematoma in FⅦ-suppressing group was (6.7 ± 1.5)mm3 and (9.8 ± 1.0) mm3,significantly higher than that in control group [(5.2 ± 1.2) mm3 and (5.5 ± 1.5) mm3] (P ＜0.01).Conclusions Level of FⅦ in vivo relates closely to the progressive hemorrhage of brain contusion in mice.Administration of FⅦ is effective to reduce the incidence of progressive hemorrhage.
