Objective To investigate the gender difference in the smile aesthetic features in aged Han Chinese with normal occlusion and its clinical significance.Methods Fifty-six aged Han Chinese (male:28,female:28,aged 60-66 years)with normal occlusion were included in this study.Smiling images of the resting-position and mandibular postural position were obtained in an anteriorposterior view.The CoSmileMAA1.0 software was used to evaluate the indices associated with the smile-aesthetic features,and its clinical significance was analyzed.Results Significant differences were noted in the nasal ala width,upper lip length,lip clearance,angle oris width in resting-position/ smiling position together with the changes of lip clearance,angle oris width,distance of inferior margin of upper lip to cutting edge of the maxillary incisor teeth,distance of superior border of lower lip to cutting edge of the maxillary incisor teeth,smile line ratio and type of smile (all P＜0.05).When the subjects were smiling,the changes of lip clearance was greater in females than in males [(10.7±1.9)mm vs.(11.3±1.6)mm,P＜0.05],the changes of angle oris width was greater in males than in females [(14.1±1.6)mm vs.(13.4±1.3)mm,P＜0.05],and the smile line ratio was less in males than in females [(0.9±0.2) vs.(1.1±0.5),P＜0.05],which indicate that the females had more attractive smile in aged Han Chinese with normal occlusion than males.The type of smile was mainly high smile in elderly females and median smile in elderly males [53.6％ (15 cases) and 60.7％ (17 cases),x2 =6.43,P＜0.05].Conclusions Significant gender difference is noted in the smile-aesthetic features in aged Han Chinese with normal occlusion.Modulation of maxillary incisor teeth length and smile line ratio can contribute to the aesthetic appearance of smiling.

ObjectiveTo investigate the clinical efficacy of the fixation of elderly fracture of proximal humerus with locking compression plate(LCP) by mini-incision approach from lateral shoulder.Methods31 elderly patients suffered from elderly fracture of proximal humerus were treated with locking compression plate(LCP) by mini-incision approach from lateral shoulder, male 13 cases, female 18 cases; aged from 56 to 72, average 62-8 years old; fractures according to Neer classification: type Ⅱ(8 cases), type Ⅲ (19 cases), type Ⅳ (4 cases). Cause of injuries: traffic accident (9 cases), falling (20 cases), other injuries(2 cases).ResultsThe patients were followed up 6 to 36 months, an average of about 24 months. Fracture healing time was 2-2 ～ 6-4 months, on average 3-7 months; No wound infection occurred. Post-operative functional score (Neer score) revealed: excellent(18 cases), good (11 cases), fair (2 cases), the ratio of excellent(18 cases), good (11 cases) was 93-5%. ConclusionFixation of elderly fracture of proximal humerus with locking compression plate(LCP) by minimally invasive approach from lateral shoulder is a safe, reliable and minimally invasive procedure with good reduction and stable fixation. Early post-operative functional exercise may be permitted for preventing shoulder joint adhesion.

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

Objective To investigate the protective effect and mechanisms of NF-?B decoy oli- godeoxynucleotides(ODNs)on rat liver graft following ischemia-reperfusion injury.Methods Ani- mals were randomly divided into 3 groups(n=8 in each group):control group,ischemia-reperfusion (IR)group,and decoy ODNs group,in which donor grafts were transfected with 120?g NF-?B decoy ODNs before graft procurement.Following 2 h of reperfusion,Kupffer cells(KCs)were isolated,and NF-?B biding activity was detected with electrophoretic mobility shift assay(EMSA),and TNF-?、IL- 6 mRNA expression was assayed by using RT-PCR method.Meanwhile,the liver and serum samples were collected,the histopathologic change of liver was examined by light microscope,and liver func- tion was analyzed.Results The NF-?B biding activity,TNF-?,IL-6 mRNA expression,and the ALT,TBIL levels in serum were significantly increased following 2 h of reperfusion in IR group as compared with those in control group(P＜0.01).A large amount of degeneration and necrosis in hep- atocytes accompanied with obvious congestion in hepatic sinusoid occurred.However,these tested in- dexes were significantly ameliorated in decoy ODNs group as compared with those in IR group(P＜0.01),and the architecture of hepatic lobules was remained.Conclusions KCs NF-?B activation fol- lowing reperfusion plays an important role in IRI in liver transplantation.Decoy strategy shows appar- ent effect on suppression of NF-?B activation,and thus inhibits the production of downstream cyto- kines,which protects the liver graft from IRI.

The bFGF plays an important role in embryonic development of tendons and ligaments and in the healing of injuried tendons and ligaments. The eukaryotic expression plasmid of rat basic fibroblast growth factor (bFGF) gene was constructed in order to further investigate the bFGF function in molecular regulatory mechanism in the repair of tendons and ligaments and to provide the foundation for the clinical application. The cDNA fragments of bFGF were cloned from the skin of rats by RT-PCR, and recombinated to the pMD18-T vector. The cDNA encoding bFGF was cloned from the pMD18-T vector by RT-PCR, digested with restriction enzyme EcoR I Pst I and bound to eukaryotic expression plasmid pIRES2-EGFP to construct eukaryotic expression plasmid pIRES2-EGFP-bFGF. The pIRES2-EGFP-bFGF was transfected into the tenocytes by lipid-mediated ransfection technique. MTT test was used to detect the biological activity of bFGF in supernatants after the transfection. The expression of type I and III collagen genes was detected by using RT-PCR. It was verified that the pIRES2-EGFP-bFGF was successfully constructed, and its transfection into tenocytes could significantly enhance the biological activity of bFGF, and increase the expression of type I and III collagen mRNA, suggesting that pIRES2-EGFP-mediated bFGF gene therapy was beneficial to the repair of tendons and ligaments.

Objective:To study the efficacy of stereotactic radiotherapy (SRT) combined with gemcitabine plus cisplatin (GP)-based chemotherapy on local recurrent non-small-cell lung cancer (NSCLC) after radiotherapy. Methods:Thirty-eight patients with local recurrent NSCLC were treated with SRT(3.00-4.85 Gy per fraction, five times every week, totally 8-12 fractions, total course of 2-3 weeks). Before SRT the patients were given two cycles of GP-based chemotherapy (gemcitabine 1 000 mg/m~2 d 1 and d 8;cisplatin 30 mg/m~2 d 1-3) and at the end of SRT they were given 4 cycles of GP-based chemotherapy. Results:Of the 38 patients,7 patients had complete response, and 23 patients achieved partial response. The overall immediate response rate was 78.95% (30/38). The 6-month and 12-month total survival rates were 71.05% and 10.53%,respectively. The median survival time was 7.8 months. Conclusion:SRT combined with GP-based chemotherapy had better short-term efficacy and the patients were tolerable. No severe short-term radiation-induced injury was observed. The long-term radiation-induced injury and long-term efficacy need further investigation.
