Objective To study the angular characteristics of facial profile in normal Han Chinese adults of Guangdong natives and the value of measurement methods adapted in this project. Methods One hundred and fifty Han Chinese adults (ratio of male to female,1∶1)were randomly chosen and parameters for computer aided angular analysis of facial soft tissues included:lateral angles:∠Ns Prn Pgs;∠Ns Prn GsPgs;∠Ns Prn Sn; As Ns Bs;∠Ns Sn Pgs;∠Gs Ns Prn;∠Cm Sn Ls and ∠Li Bs Pgs. front angles: ∠Zyr Rc Mes; ∠Zyl Lc Mes; ∠Exr Exl Sn; ∠Exl Exr Sn; ∠Exr Sn Exl; ∠Enl Enr Sn; ∠Enr Enl Sn; ∠Enr Sn Enl; ∠Sn Chr Chl; ∠Sn Chl Chr and ∠Chr Sn Chl.Results Lateral angles ∠Ns Prn Sn and ∠Li Bs Pgs,in male were larger significantly than that those in female, but ∠Gs Ns Prn in male was smaller significantly than that in female. Front angles,∠Zyr Rc Mes and ∠Zyl Lc Mes,in male were larger significantly than those in female.Conclusion Angular analysis plays a unique role in the measurement of facial soft tissue profile. There is a difference of facial soft tissue profile between male and female Han Chinese.

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P

From cooperation between World Federation of Acupuncture-Moxibustion Societies (WFAS) and World Health Organization, works of academics and standardization, acupuncture-moxibustion education, technique service, organization development, etc., the 27-year development of WFAS since 1987 was summarized and reviewed in details. The growth of WFAS witnesses and promotes the development of acupuncture and moxibustion in the world, so by learning the experience and lessons, WFAS could have a wider path, becoming a core organization for communicating and promoting the development of acupuncture, even the traditional medicine in the world.

Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.

This research is to establish an HPLC method for the simultaneous determination of ophiopogonin D, ophiopogonin D', ophiopogonin C, deacetylophiopojaponin A and ophiogenin-3-O-α-L-rhamnosyl-(1-->2)-β-D-glucoside in Ophiopogonis Radix. HPLC-ELSD analysis was performed on a Kromasil 100-5 C₁₈ column (4.6 mm x 250 mm, 5 µm), with the mobile phase of acetonitrile (A) -water (B) in gradient elution mode (0-45 min, 35%-55% A), at a flow rate of 1 mL · min⁻¹. The column temperature was 35 °C and the drift tube temperature was 100 °C in a gas flow rate of 3.0 L · min⁻¹. The result showed that baseline of all the 5 constituents was well separated, and every constituent had wide linearity range and good linear relation (r > 0.999). The recovery rate was between 95.75% and 103.1%. The new established method for simultaneous determination of saponin constituents in Ophiopogonis Radix was sensitive and has good, repeatability. It could be applied to quality evaluation of Ophiopogonis Radix.

Objective To observe the process of Vibrio vulnificus inducing dendritic cell strain apoptosis.Methods We established the mixed culture model of mouse dendritic cell ( DC 2.4 strain) and Vibrio vulnificus( Vv1.1758 strain ),analyzed morphological characteristics of cell apoptosis by DAPI fluorescence staining,detect DNA fragmentation level of apoptosis cells by DNA Ladder assay,analyze DC2.4 apoptosis rate by Annexin V FITC/PI staining,determine activities of caspase-3 and caspase-8 by means of spectrophotometric method and detect changes of mitochondrial transmembrane potential ( △ Ψm ) by JC-1 fluorescence labeling.Results After Vv1.1758 strain and DC2.4 cell were mixed and cultured for 4 h,DAPI fluorescence staining showed typical apoptosis characteristics-chromatin condensation and marginalization; DNA agarose gel electrophoresis showed apoptosis band; apoptosis rates at 2,4 and 6 h were respectively (37.8±9.8) ％,(54.3 ± 12.7 ) ％ and ( 68.2± 14.6 ) ％ ; Mitochondrial transmembrane potentials (△Ψm) at 1 h,2 h and 4 h reduced by 7.1％,16.1％ and 46.7％ respectively; caspase-8 activity increased at 1.5 h and reached the peak at 2 h [ (2.48±0.19) U/μg],while caspase-3 activity started to increase at 3h and reached the peak at 4 h [ ( 1.91 ±0.16) U/μg ].Conclusion Vibrio vulnificus could induce dendritic cells by two pathways: reducing mitochondrial transmembrane potential and activating caspase-8 promoter and finally activate effector caspase-3 to promote apoptosis.

Objective To investigate the invasion,internalization and the organelles damage of the cultured dendritic cells ( DC2.4 strain) during Vibrio vulnificus (Vv) infection.Methods The study model was the cultured DCs infected by Vv 1.1758 strain.Electron microscopy was used to observe the localization of bacteria in different time point of infection,cell morphology and the process of organelles changes.The cytoskeleton structure including the microfilaments and the microtubules rearrangement was examined by the fluorescence microscope.Results The Vv were pinocytosed into the DC cells through double-sides,and localized at 1-2 μm of the inner side membrane.It cost 1.27,1.87,3.43 hours reaching the infection ratio of 25％,50％,75％,respectively.Using electron microscopy,the DCs had been observed the phagosome formation within 1h,chromatin activation within 2 h,chromatin aggregation 4 h,and the significant cytoskeleton structure disruption within 6 h.Endoplasmic reticulum,mitochondria and lysosomes became swollen.In DCs,the protruding filaments gradually reduced,and their shape changed from the point-like to the linearlike aggregation at the inner side of the plasma membrane,extended microtubules disappeared,the microtubules at the outside nuclear membrane striking rearranged.Conclusion After DC was infected by Vv,the bacteria were pinocytosed into the inner side of DC membrane,and the microfilaments were observed to move from the cytoplasm to cell membrane.In addition,the microtubules moved from the synapse and the cell membrane to the nuclear membrane.The high lethality of Vv could provoke to the DCs cytoskeleton rearrangements.
