The authors first expound the connotations and origin of the legal person management structure and then discuss the following issues: the dual relation of agency by agreement characteristic of medical institutions, the need to take management structure as the priority of hospital reform in delegating powers to lower levels, the primary strategies and major means of the legal person management structure of corporations, and questions related to the management structure of the medical industry abroad: who should become the agent of the patient, how to unify the interests of the agent and the consignor by means of reasonable remuneration designs, etc. Finally the authors give an account of the inspiration that can be drawn from the legal person management structure to the public hospital property right system reform in China.

Objective To explore the association between rs7049105, rs647188, rs1333035 of chromosome 9p21 and the LAS among Chinese Han population of Changsha;to explore the association between rs7049105, rs647188, rs1333035 and the LAS among patients with evidence of cephalic and cervical vessel atherosclerosis. Methods The present study com?prised 229 LAS patients and 233 healthy controls. The 233 controls which we defined control group 1. In the controls, 150 (64.38%)controls with evidence of atherosclerosis were defined as control group 2, 83(35.62%)controls without evidence of atherosclerosis were defined as control group 3. The sample genotyping was detected using MALDI-TOF-MS. Results There was no polymorphism of rs647188 among case group and control group 1. There was no significant difference in the polymorphism distribution of rs7049105 and rs1333035 between the case group and control group 1 and 3 (P>0.05). There may be no significant different in the polymorphism distribution of rs7049105 between the case group and control group 2 . The rs1333035 was associated with risk of LAS among patients with evidence of cephalic and cervical vessel atherosclerosis (χ2=6.502,P=0.039). Conclusions The rs10757274 and rs7049105 polymorphism in the chromosome 9p21 may not be as?sociated with risk of LAS among Han population of Changsha. There may be no polymorphism of rs647188 among Han popu?lation of Changsha. The rs1333035 polymorphism may be associated with plaque rupture and thrombosis.

Phytoestrogens, which can bind with estrogen receptor and produce estrogen-like effects, are a kind of nonsteroidal compound in plant. Phytoestrogens chemically include isoflavones, coumarins, lignans and other compounds. Phytoestrogens are selective estrogen receptor modulator, and have therapeutical effects on breast cancer, prostate cancer, cardiovascular disease, menopausal symptoms, osteoporosis and other disease, however, do not produce stimulatory hyperplasia effects on uterus, mammary glands and other tissues and organs with positive estrogen receptor. Long-term exposure or excessive use of phytoestrogens maybe affects male reproductive system and hematopoietic function of fetus. Some questions need to be further studied, such as evaluation criteria on biological activity, adverse effects, and action mechanism of phytoestrogen. This review covers plant sources, chemical structure, pharmacological activity and safety of phytoestrogens. It will provide a useful reference for intensive research and rational utilization the phytoestrogens.

Objective To analyse the femoral head coverage rate of CT in evaluation of Salter osteotomy for developmental dislocation of hip(DDH) in children. Methods Thirty-eight patients with unilateral DDH for Salter osteotomy were enrolled,and X ray photography of pelvis and spiral CT scanning of femoral articulation were performed one week before and 6 months after Salter osteotomy.The femoral head coverage rate of X ray and that of CT were calculated and compared.Another 38 children with normal femoral articulation were served as controls. Results The femoral head coverage rate of X ray was significantly higher than that of CT in patients with DDH(P

Objective Our hypothesis was if we rendered host' s cytotoxic tumor lymphocytes insensitive to TGF-β,these immune cells could be able to overcome the TGF-β mediated immunosuppression and reject the tumor.We aimed to develop a lentivirus mediated gene transfer program incorporating a herpes simplex virus thymidine kinase(HSV-tk)in our dominant negative TGF-β type Ⅱ receptor(TβRⅡDNglytk)expression vector.So we first need to construct the lentiviral pLenti6/V5-D-TOPO vector containing TβRⅡDNglytk and produce the recombinant lentivirus as the transfection vector.Methods PCR were used to amplify the genes TβRⅡDN and HSV-tk from the respective plasmids.Then the genes were linked by recombinant PCR technology to construct the fusion gene TβRⅡDNglytk and control vector TRANSglytk.According to the operation manual from the Invitrogen company,TOPO cloning technology was used to construct the plasmids of pLenti6/V5-D-TOPO(R)-TβRⅡDNglytk and pLenti6/V5-D-TOPO(R)-TRANSglytk.Both of the constructed plasmids were verified by sequencing.ViraPowerTM Lentiviral System and 293 FT cells provided by Invitrogen were used to produce the recombinant lentivirus vector,the tillers of the lentivirus were determined by 293 cells.Results The construction of the plasmids of pLenti6/V5-D-TOPO(R)-TβRⅡDNglytk and pLenti6/V5-D-TOPO(R)-TRANSglytk were completed succefully.The DNA sequencing results showed that both the plasmids were constructed correctly.Using them we successfully produced infectious lentivirus vectors with appropriate tilters.Conclusions Using TOPO cloning technology in the construction of the plasmids of pLenti6/V5-D-TOPO(R)-TβRⅡDNglytk and pLenti6/V5-D-TOPO(R)-TRANSglytk and recombinant PCR in the fusion genes is feasible.Recombinant PCR combine with TOPO cloning technology can be a simple,highly efficient and rapid way to construct lentiviral vector.The production of infectious lentivirus with appropriate tilters using 293FT is suitable and feasible.The construction of pLenti6/V5-D-TOPO(R)-TβRⅡDNglytk and production of the infectious lentivirus will lay a foundation for immunotherapy of prostate cancer.

Objective To evaluate the role of vascular endothelial growth factor-D(VEGF-D)in lymphangiogenesis of breast cancer,and investigate its relationship with some clinicopathological parameters and prognosis. Methods VEGF-D expression was detected in 85 cases with primary breast carcinoma by immunohistochemistry,and VEGF-D mRNA was detected by RT-PCR.Podoplanin monoclonal antibody was used to mark lymphatic endothelial cell and lymphatic vessel density(LVD) was counted.The relationship among the aboved parameters,clinicopathological parameters and prognosis was analysed. Results It was revealed by immunohistochemistry that VEGF-D expression was ranked by 5 levels: negative,n=5(5.88%);"+",n=17(20%);"++",n=34(40%);"+++",n=22(25.88%),and "++++",n=7(8.24%).VEGF-D expression was associated with tumor lymph node metastasis and TNM clinical stage(P

OBJECTIVE To investigate the hepato-protective mechanism of thymoquinone (TQ) onthe development of acetaminophen (APAP)- induced liver injury. METHODS In vivo, male kunming mice were injected with a single dose of 300 mg·kg-1 APAP. Some mice were pretreated with TQ (5 or 20 mg·kg-1) and N-acetylcysteine (NAC, 300 mg·kg-1) 2 h before APAP injection. Mice were euthanized at 2 h, 6 h, 12 h after APAP treatment. In vitro, human Chang liver cells were incubated with 3.125, 6.25 or 12.5 μmol·L-1 TQ, 10 μmol·L-1 SP600125 and 500 μmol·L-1 AICAR in the presence of APAP for 24 h. Cell viability were analyzed by MTT assay, protein expressions were assessed by Western blot. RESULTS TQ pretreatment significantly reduced serum aminotransferase and increased hepatic gluta?thione (GSH) and glutathione peroxidase (GSH-PX) activities, while significantly inhibited interleukin-1β(IL-1β) levels. TQ significantly inhibited c-Jun N-terminal kinase (JNK), extracellular signal regulated kinase (ERK) and P38 phosphorylation induced by APAP. Moreover, TQ inhibited phosphatidylinositol 3- kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling activation and activated AMPK phosphorylation induced by APAP. In addition, TQ inhibited signal transducer and activator of transcription 3 (STAT3) phosphorylation on APAP-induced liver injury. In vitro, APAP enhanced JNK phosphorylation and attenuated AMPK phosphorylation in Chang liver cells, and these effects were blocked by pretreatment with TQ, SP600125 (JNK inhibitor) and AICAR (AMPK activator). CONCLUSION Our findings suggest that TQ may actively prevent APAP-induced liver injury, and this effect may be mediated by JNK and AMPK signaling pathways.
