Objective To investigate the possibility of plastic and cosmetic operation incorporating epicanthoplasty with the double-eyelid procedure in one stage to achieve a more subtle scar in epicanthus patients with single eyelid. Methods After designing incision line of the epicanthic flap, double-eyelid line and the lower eyelid incision curved line, we cut the medial canthus skin transversely to reach a new medial canthus point, incised the part of front angle of medial palpebral ligamentum longitudinally and fixed the end point of front angle of medial palpebral ligamentum to nasal dorsum fascia firmly. Double eyelid operation was routinely performed to remove redundant small triangle skin as well as some patchy of orbicularis on the new medial canthus point. Along with eyelid edge about 1 to 2 mm to eyelash, the temporal side was cut with curved line till its disappearance by eyelid's "cat ear". The lower eyelid flap was separated downward and the superfluous flap and some patchy of orbicularis cut. The skin was su-tured to make postoperative scar hidden, blepharophimosis increased and the fold disappeared. Results 46 eyes (23 cases) were operated and satisfactory aesthetic results were obtained. Palpebral fissure was enlarged to 2 to 4 mm with epicanthic scar disappearance and formation of double-eyelid. Conclusions This is a simple and effective procedure with hidden epicanthic scar and the double-eyelid blepharoplasty could be performed simultaneously. Most patients receive satisfactory results during the 0.5 to 2 years' follow-up period except 2 cases with mild proliferation of epicanthus in half a year. It is especially suitable to correct the severe epicanthus palpebralis or epieanthus tarsalis.

Objective To study the relationship between macular pigment optical density (MPOD) and serum concentration of lutein and zeaxanthin in an adult population.Methods Twenty patients with mild cataract and 39 healthy subjects were enrolled in this study,including 15 males and 44 females.The average age was 43.75 years.Fifty-three subjects were non-smokers and 6 male subjects were smokers.Two subjects preferred meat diet,22 preferred meat-less diet,and 35 have balanced diet.MPOD was measured using heterochromatic flicker photometry at 0.25,0.5,1.0 and 1.75 degrees,and serum concentration of lutein and zeaxanthin was measured using high-performance liquid chromatography.The relationship between MPOD and serum concentration of lutein and zeaxanthin was analyzed.The differences of serum lutein and zeaxanthin between different gender,smokers and non-smokers and subjects with different dietary pattern were also analyzed.Results MPOD at 0.25,0.5,1.0 and 1.75 degrees were 0.59,0.48,0.34 and 0.18,and the average concentration of lutein and zeaxanthin were (0.45± 0.16) μmol/L and (0.11 ± 0.04) μmol/L respectively.Serum concentration of lutein and zeaxanthin in males were slightly higher than that in females,but it was not statistically significant (t=1.13,0.86;P=0.27,0.40).The differences of serum lutien and zeaxanthin between smokers and non-smokers (t=0.15,-0.11;P=0.87,0.91),among subjects of 3 dietary patterns groups were not statistically significant (Flutein=3.87,4.05,0.18;P=0.83,0.81,0.99.Fxeaxanbin=0.99,1.51,0.52;P=0.85,0.68,0.72).There was no correlation between MPOD and serum concentration of lutein (r=-0.06,-0.02,-0.07,0.03;P＞0.05) and zeaxanthin(r=0.02,0.12,0.09,0.11;P＞0.05).Conclusion MPOD was not statistically significantly correlated with serum concentration of lutein and zeaxanthin in the studied population.

Objective To discuss the intervention effect of four oral care model on compliance of atomizing inhalation and mouth and throat complications in outpatient infants and young children patients. Methods A total of 480 cases of children patients using budesonide inhalation for the treatment of respiratory tract infection were divided into the observation group(n=260)and the control group (n=220) according to the time sequence. The control group received conventional nursing, the observation group used quaternity oral care model in nursing care. The compliance and occurrence of complications in the mouth and throat were observed between the two groups. Results In the observation group with nebulae inhalation compliance was 79.2% (206/260), evidently higher than that in the control group the compliance of 58.6%(129/220) (χ2=23.97,P<0.01). The incidence of oral herpes and ulcers in the control group was 2.73%(6/220), and 0.77%(2/260) in the observation group, but no significant difference was seen (χ2=2.79, P>0.05). The incidence of thrushes was 3.64%(8/220) in the control group, and none occurred in the observation group, which showed significant difference (χ2=9.62, P<0.01). Conclusions Using quaternity oral care model in corticosteroid nebulae inhalation patientscan increase compliance and decreasecomplications of oral and throat of outpatient children.

Objective To study the radioprotective effect of polypeptide from Chlamys farreri (PCF) on ultraviolet B(UVB)-irradiated murine thmocytes in vitro. Methods The murine thymocytes were exposed to UVB radiation. MTT method was used to detect the cell viability. The activities of intracellular glutathione peroxidase (GSH-Px), superoxided dismutase(SOD) and catalase (CAT) were measured. Intracellular reactive oxygen species (ROS) and the effect of PCF on UVB-induced apoptosis were investigated by flow cytometry. Results PCF could greatly enhance the viability of murine thymocyte and markedly promote the activities of GSH-Px, SOD and CAT, while the amount of ROS was decreased. PCF could inhibit UVB-induced thymocyte apoptosis. Conclusion PCF has significant radioprotective effects on UVB-irradiated murine thymocytes in vitro.

Objective To investigate the effect of radiofrequency ablation(RFA) in the treatment of small liver cancer.Methods In recent 6 years,130 patients with primary or secondary liver cancer(≤5cm in diameter)were treated by RFA,among which 86 cases were primary,and 44 cases were secondary liver cancer.Among the 130 cases,18 received RFA plus TAEC,and 20 had RFA combined with PEI.Results Overall 1-and 3-year survival rate was 91.3% and 77.7% respectively.Complications occurred in 7 cases,including biliary fistula,intestinal fistula,and slight burn of skin.There was no death in this series.Conclusions RFA is an effective and safe therapeutic approach for small liver cancer ≤5cm in diameter.Its effect may be similar to that of surgical resection.

This article presents the design of a bioreactor using hollow fiber membrane and, isolated hepatocytes of suckling pigs, and the experimental study of its efficacy in vitro. Liver cells were harvested from suckling pigs with collagenase perfusion in situ, and parenchymal and non-parenchymal hepatocytes were cocultured in a hollow fiber module which was rotated sporadically. Bioartificial liver(BAL) was developed using this bioreactor,and the BAL was perfused with ascites of patients suffering from liver cirrhosis. The yield of viable hepatocytes was (6.29 +/- 0.37) x 10(8) cells, and cell viability was greater than 84%. Hepatocytes aggregated to multi-cells spheroids after being rotated every thirty minutes for three hours. The hepatocytes in the bioreactor could synthesize urea. Total billirubin was decreased, and AST was significantly increased in the group of bioreactor, as compared with that in the control group. Glucose decreased in the group of bioreactor,whereas there was no significant descent in the control group; and the difference between the two groups was significant. The above results demonstrate that this bioreactor is effective for decreasing total bilirubin and glucose.
