OBJECTIVETo explore the mechanism of the aging deformity of tear trough through the anatomic study of the tear trough region.

METHODS13 adult cadaveric heads (26 sides), including 9 male heads (18 sides) and 4 female heads (8 sides), aged 22-78 years old, were used. Anatomic study was performed around the orbital, especially tear trough region, with microsurgery instrument under microscope( x 10 times). The lower orbicularis retaining ligament was dissected and exposed. The anatomic location was recorded and photographed.

RESULTS(1) The anatomic layers of the tear trough region contains skin, subcutaneous tissue, orbicularis oculi muscle, periosteal membrane. There is no subcutaneous fat above the tear trough, while it exists below the tear trough, called malar fat pad. (2) There is a natural boundary between the septal and the orbital portions of the orbicularis oculi muscle of lower eyelid at surface of the orbital bone. The natural boundary, projected on the body surface corresponds to tear trough. The width of boundary is (2.06 +/- 0.15) mm on the vertical line through inner canthus and (3.25 +/- 0.12) mm on the vertical line through the lateral margin of the ala. The septal portion and the orbital portion of the orbicularis oculi muscle began to merge in (16.56 +/- 0.51) mm to inner canthus. (3) There is ligament attachment in the medial, upper and lower orbital and no ligament attachment in the lateral orbital. Orbicularis retaining ligament of lower eyelid is divided into two layers. (4) The medial of the upper layer of the orbicularis retaining ligament in lower eyelid originates from orbital margin and from preorbital walls laterally in (16.10 +/- 0.43) mm to the medial of lateral orbital margin, through orbicularis oculi muscle and ends at the skin. The lower layer of the orbicularis retaining ligament of lower eyelid originates from preorbital walls through orbicularis oculi muscle and its superficial fat, then ends at the skin.

CONCLUSIONSThe length of tear trough is (16.56 +/- 0.51) mm, the width of tear trough is (2.06 +/- 0.15) mm and (3.25 +/- 0.12) mm on the vertical line through inner canthus and the lateral margin of the ala nasi respectively. The main reason of the aging deformity of tear trough attributes to the increased distance between the upper and lower layers of the orbicularis retaining ligament in lower eyelid, which is caused by loose of the orbicularis retaining ligament and its underlying fat atrophy or decline.

Objective To study the impact of hepatitis B virus (HBV) infection on the activity of cord hematopoietic stem cells. Methods CD34+ cells were isolated from healthy human cord blood by miniMACS. Cells were cultured in IMDM complete culture medium containing stem cell factor (SCF),fms-like tyrosine kinase 3 ligand (FL), thrombopoietin (TPO), interleukin-3 (IL-3) and 10% fetal bovine serum. High copies HBV were added to the culture system. The proliferation of stem ceils and virus replication were observed. Following the proliferation, dendritic cells (DCs) were induced by adding granulocyte-macrophage colony-stimulating factor and IL-4. Morphous of stem cells and DCs were observed by microscope and the cell surface molecules were detected. Results The proliferation of stem cells infected with HBV was significantly lower than that of healthy stem cells (P＜0.01),and enhanced after adding cytokines (P＜0.01). At the same time, HBV replication was increased after adding cytokines in the culture system (P＜0.01), but the proliferation was still lower than that of healthy stem cells with cytokines in the culture medium (P＜0.05). Dane particles were found in the cytoplasma of stem cells infected with HBV by electron microscope. The expression of CD80,CD86 ,CD1a and HLA-DR on DCs derived from HBV infected stem cells were all lower than those on DCs from non-infected stem cells (P＜0.01). Conclusions HBV could infect CD34+ stem cell and the proliferation of the stem cell could enhance the virus replication. HBV could not only inhibit the proliferation of stem cells,but also down-regulate the immuno-phenotype expression of DCs derived from CD34+stem cells.

Objective To identify the anatomical basis for aging orbit-malar fold forming orbitmalar groove and its underlying mechanism.Methods Thirteen cadavers (26 hemifaces) were dissected in this study (9 male and 4 female heads).All specimens were fixed in 10％ formalin,with age ranges from 22 to 78 years.The lateral orbital region was dissected in layers by mieroinsrument using 10 X loupe magnification,especially at the palpebral and the lateral orbital part,and then the anatomy layer was described; the lateral orbital thickening (LOT) was performed carefully to evaluate whether there were multiple anatomical contributions to anatomy.Anatomic observations were systematically recorded,sketched,and photographically documented.Results The lateral orbital layers included skin,subcutaneous adipose tissue,orbicularis oculi muscle,middle temporal fascia,and periosteum.The lateral orbital thickening was a triangular condensation of fascia,which extended over the lateral orbital rim onto the adjacent medial tem~ral fascia,the lateral orbital thickening was measured (9.28 ±0.45) mm in transverse width from Vertex triangle to lateral canchal,the inner part of the LOT sanwiched between orbibularis and obital septum,which consisted of upper lid and lower lid part,the lower lid part presented transverse V shape,the top part of the transverse V was adhesive to fascial tissue over tarsal plate.The distance to lateral canthus angular was 21.69-37.21 mm,and the under part was adhesive to low orbital rim the low arm distance to lateral canthus angular was (13.55 ±0.52) mm.Vertex of.V to lateral canthus angular vertical distance was (11.35±0.27) mm.Conclusions The reason why aging orbit-malar fold forms orbital-malar groove is the atrophy of the subcutaneous adipose tissue and the middle temporal fascia fat.

Objective To observe the effects of Weipixiao on the ultrastructure of gastric mucosa capillaries in rats with precancerous lesions of gastric cancer ( PLGC). Methods The rats were randomized into six groups, including normal group, model group, Vatacoenayme Tablets group ( 0.2 g·kg-1·d-1) , and high-, middle-, and low- dose Weipixiao groups ( 15, 7.5, and 3.75 g·kg-1·d-1 respectively) . The rats received spontaneous intake of N-methyl-N’-nitro-nitrosoguanidine ( MNNG, 200 μg/mL) solution combined with irregular diet and intragastric administration of purgative herbs Xiao Chengqi Decoction ( 2 mL, containing 1 g/mL crude drug) for 18 weeks to induce spleen-deficiency PLGC. The pathological changes in gastric mucosa and the ultrastructure of gastric mucosa capillaries were observed under the transmission electron microscope. Results The model has been established successfully. Transmission electron microscopy results in the model group showed as severely swollen endothelial cells of gastric mucosa capillaries, severely-narrowing or even blocked vascular lumens, rough and discontinuous basement membrane, and swollen, degenerated or even absent pericytes. And the ultrastructure of gastric mucosa capillaries in high-, middle-, and low- dose Weipixiao groups were improved to some degrees, the effect of low-dose Weipixiao group being the best. Conclusion The improvement of the mucosal microcirculation of spleen-deficiency PLGC rats may be one of the pathohistological mechanisms of Weipixiao for spleen-deficiency PLGC.

Objective To investigate the forming mechanism of smile anatomically,and to analyze the changes of aging characteristics of mid-lower face.Methods Ten (with 20 sides) adult fresh cadaveric heads were fixed by formalin,and then nasolabial fold morphology was observed under 10X operating magnifying glass,and compared with alteration of the middle and lower face aging features under the state of smiling and static according to observation from 50 doctors' and out-patients' photos.Results The nasolabial fold was the boundary between fatty and fat-free zone in the middle face,the lateral side of which was malar fat pad.The nasolabial fold was the linear area,which was formed by the insertions of seven mimetic muscles on the skin.When smiling,the nasolabial fold and cheek groove,got deep and extended,cheek stripe became obvious.While smiling,malar fat pad shifted up,and tear trough became deformity..64％ disappeared and 36％ getting shallow and appearance improved; orbit-malar fold showed 100％ horizontal part disappeared,74 ％ vertical part became shallow and improved,and 26％ stayed stable; mid-cheek fold showed 78％ dissovled,22％ getting shallow and improved; Labiomandibular fold showed 100％ Ⅲ degree disappeared,100％ Ⅱ degree dissovled,74％ Ⅰ degree disappeared,and 26％ getting shallow and ameliorated; submaxilla line showed 18％ getting smooth and 82％ remained.Conclusions Smiling is produced by movement of mimetric muscles,and its orgin is from nasolabial fold.A smile could make malar fat pad upwards to mask some aging characteristics of middle and lower face,which is helpful to form a younger face.

OBJECTIVETo investigate the modulating effect on lipid and gene expressions of CPT I A caused by berberine (Ber) in experimental hyperlipidemia rats.

METHODMale SD rats were randomly divided into 5 groups according to the blood lipid values: normal group, hyperlipidemia group, 300 mg x kg(-1) x d(-1) Ber-treated group, 60 mg x kg(-1) x d(-1) Ber-treated group, and 7.2 mg x kg(-1) x d(-1) lovastatin-treated group. Normal group were fed with base diet and other groups were fed with high fat and cholesterol diet. 12 weeks after drugs were given the TC, TG, LDL-C, and HDL-C from rat blood samples were tested by automatic biochemistry analyzer. Gene expressions of CPT I A and PPARalpha were evaluated by RT-PCR and Western blot, respectively.

RESULTIt was shown that Ber significantly decreased TC and LDL-C, but increased HDL-C in dose-dependent manner, elevated expressions of CPT I A mRNA and protein without influence on PPARalpha expression. Similar effects from lovastatin on lipidemia were observed except the Ber effect on CPT I A gene expression.

CONCLUSIONBer has modulating effect on the lipid metabolism, the mechanism of which may be by promoting the CPT I A gene expression.

In order to research the infrared radiation characteristics of the skin covering Traditional Chinese acupuncture points, which are NeiGuan in the forearm and LaoGong in the center of the palm, we detected continuously the infrared radiation spectra of the human body surface by using Fourier Transform Infrared Spectroscopy. The experimental results showed that firstly, the differences of the infrared radiation spectra of the human body surface were obvious between individuals. Secondly, the infrared radiation intensity of the human body surface changed with time changing. The infrared radiation intensity in two special wavelength ranges (wavelengths from 6. 79 microm to 6. 85 microm and from 13. 6 microm to 14. 0 microm) changed much more than that in other ranges obviously. Thirdly, the proportions of the infrared radiation spectra changed, which were calculated from the spectra of two different aupuncture points, were same in these two special wavelength ranges, but their magnitude changes were different. These results suggested that the infrared radiation of acupuncture points have the same biological basis, and the mechanism of the infrared radiation in these two special wavelength ranges is different from other tissue heat radiation.
