0.05), but the lesion detection sensitivity of SSD and Raysum display were lower than that of UGI(? 2=4.17,7.11, and 5.14,4.17, P0.05). Excess fluid remained in the stomach and patient respiratory movement during breath holds were the reasons causing severe artifacts (6.1%) that influenced the diagnostic evaluation. Conclusion The performance of CTVG was equivalent to UGI in the detection of advanced gastric carcinoma and superior to UGI in the Borrmann′s classification. CTVG has potential in the detection of early gastric carcinoma. The value of SSD and Raysum display was limited in the evaluation of gastric carcinoma when used alone clinically.

Objective To compare open versus closed reduction in treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours.Methods We retrospectively reviewed 51 children who had been treated at our department for femoral neck fracture between May 2005 and May 2012 after their reduction had been delayed for more than 24 hours.They were 37 boys and 14 girls,1.7 to 15.5 years of age (average,9.1 years).According to Delbet's classification,27 cases belonged to type Ⅱ,18 to type Ⅲ,and 6 to type Ⅳ.Of them,18 underwent closed reduction and 33 open reduction.Their complications were recorded in detail.Their therapeutic results were evaluated according to Ratliff's criteria and compared between the 2 methods of reduction.Results The 51 children were followed up for an average of 36.7 months (range,from 17 to 61 months).Anatomic reduction was achieved in 6 cases in the closed reduction group (33.3％) and 29 cases in the open reduction group (87.9％),respectively.All fractures healed after an average of 10.9 weeks (range,from 9 to 13 weeks),with one exception of nonunion in the closed reduction group.The incidence of femoral head necrosis in the closed reduction group (27.8％,5/18) was significantly higher than that in the open reduction group (15.2％,5/33) (P ＜ 0.05).According to the Ratliff's evaluation at the final follow-ups,the good to excellent rate in the closed reduction group(66.7％,12/18) was significantly lower than that in the open reduction group (84.8％,28/33) (P ＜0.05).Coxa vara occurred in 3 children in the closed reduction group but in none in the open reduction group.Conclusion Open reduction with internal fixation may lead to better outcomes than closed reduction in the treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours,probably because open reduction can result in better reduction quality.

Objective To evaluate effects of incorporating tetrapod-like zinc oxide whisker (T-ZnOw) antibacterial agent on the antibacterial activity of composite resin, compared with that of the silver-based inorganic antibacterial agent. Methods The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the two different antibacterial agents against Streptococcus mutans were investigated using the broth dilution test Then the antibacterial activities of the self-cured composite resin specimens with different incorporating concentrations of the two antibacterial agents were evaluated using direct contact test And the antibacterial activities of the resin specimens were examined again after 3 months of accelerating aging. Results The MIC (MBC) of the T-ZnOw antibacterial agent and silver-based inorganic antibacterial agent were 0.15625(0.3125) g/L and 0. 15625(0.15625) g/L When the concentrations of T-ZnOw added to composite resin were 3%, 5% , and 10% (w/w), the antibacterialratios of the resin specimens were (84.85±5.16)%, (94.22 ± 3.73)%, and (99.43±0.48)%respectively. When the concentrations of the silver-based antibacterial agent added to composite resin were 1%, 3%, and 5%, the antibacterial ratios were (71.01±7.67)%, (90.76±5.91)%, and (97. 19 ±4.10)% respectively. The antibacterial ratios of the resin specimens containing 5% of both antibacterial agents were (89.89 ± 5.55) % and (78.79 ± 7.81) % respectively after 3 months of accelerating aging.Conclusions Incorporation of the T-ZnOw antibacterial agent in composite resin can improve the antibacterial performance of the resin, and the resin exhibits better antibacterial performance than that incorporating silver-based inorganic antibacterial agent after 3 months of aging.

OBJECTIVEThis paper presents the experience in using the reverse buccinator musculomucosal flap for repairing the defect following excising inverted papilloma of the nose.

METHODSAfter the inverted papilloma of the nose was excised through an endonasal approach, the reverse buccinator musculomucosal flap supplied by the retrograde blood flow of the anterior buccal artery was harvested and sutured to the defect through the ora-nasal tunnel. The procedure was performed on three patients.

RESULTSThe postoperative course was uneventful. All the flaps survived completely.

CONCLUSIONSThe technique provides the solution to prevent nasal stricture from cicatricial contracture after excising inverted papilloma. In the operation, excising the inverted papilloma and repairing the defect was performed simultaneously, saving another operation for the secondary deformity. The technique is also applicable to the treatment of existing cicatricial stricture of the nose.

OBJECTIVETo study the anatomy of mandibular bone flap pedicled with temporal muscle for midfacial bone defects.

METHODSThe shape and blood supply of the temporal muscle and mandibular ramus, as well as their relationship, were observed and measured in 30 sides of adult head specimens.

RESULTSThe temporal muscle has a fan-shaped main portion, then is scattered into three bundles as anterolateral, anteromedial, posterior bundles, which end respectively at anterior border of ramus, the temporal ridge and posterior portion of coronoid process. Then the muscle goes downward until it reaches the distal side of the third medial surface molar and attaches the 3/4 of medial surface of anterior portion of ramus. The blood supply of temporal muscle includes the medial temporal artery with external diameter of (0.76 +/- 0.20) mm, the anterior deep temporal arteries with external diameter of (0.79 +/- 0.21) mm, posterior deep temporal arteries with external diameter of (0.98 +/- 0.64) mm, the accessory deep temporal artery formed by many little branches. The anterior part of ramus is supplied by the periosteal arteries and the bony perforator of the deep temporal arteries. Rectangular ramus of mandible was divided into anterior portion and posterior portion by the line linking the lowest point of mandibular notch, mandibular foramen and mandibular canal. Anterior portion can supply a bone flap with a size of (46.67 +/- 6.85) mm x (17.98 +/- 2.64) mm x (11.49 +/- 0.99) mm.

CONCLUSIONSThe mandibular bone flap pedicled with temporal muscle has a reliable blood supply and abundant bone volume. It is feasible to design a mandibular bone flap pedicled with temporal muscle for midfacial bone defect.

OBJECTIVETo investigate the therapeutic effect and characteristic of dynamic hip screw with modified reamer (MDHS for short) in the treatment of the intertrochanteric fracture in the elderly.

METHODSFifty-four patients with intertrochanteric fracture from Aug. 2007 to Dec. 2008 were retrospectively analyzed. Among them, 27 patients were treated with MDHS, including 12 males and 15 females with an average age of 79.4 years old ranging from 69 to 93 years; according to modified Evans classification, there were 3 cases of type I , 12 cases of type II, 8 cases of type III, 4 cases of type IV. The other 27 patients (10 males and 17 females), aged from 66 to 88 years old (average 77.2), were composed of 4 cases of type I, 14 cases of type II, 6 cases of type III, 3 cases of type IV. The fracture healing time,forepart movement time,percentage of loosening screw and hip joint function were compared between two groups.

RESULTSAll 54 patients were followed up for 21 to 36 months (means 27.6 months). All fractures were bone healing. The time of fracture healing were compared between two groups,there were no significant difference (P>0.05). The forepart movement time of MDHS group (14.2 +/- 2.1) was shorter than that of DHS group (18.9 +/- 3.1) (P<0.05). The loosening screw of MDHS group (1 case) was less than that of DHS group (8 cases) (P<0.05). The Harris score of hip joint function of MDHS group (87.8 +/- 4.7) was higher than that of DHS group (83.3 +/- 7.5) (P<0.05).

CONCLUSIONMDHS has several advantages on wider indications, stronger holding power,early forepart movement time, fewer complications, which is a good choice for osteoporotic intertrochanteric fracture.

Elevated serum levels of interleukin-10 (IL-10) have been reported in patients with Kawasaki disease (KD). IL-10 reduces the inflammatory actions of macrophages and T cells and it may play a significant role in the regulation of inflammatory vascular damage associated with systemic vasculitis. The aim of this study was to examine whether -592 IL-10 promoter polymorphism is a susceptibility or severity marker of KD in Chinese patients in Taiwan. The study included 105 KD patients and 100 normal controls. Genotype and allelic frequencies for the IL-10 gene polymorphism in both groups were compared. There were no significant between-group differences in the genotype distribution of IL-10 A-592C gene polymorphism (P=0.08). However, the frequency of the -592*A allele was significantly increased in the patients with KD compared with controls (71.9% vs. 61.0%, P=0.019). The odds ratio for developing KD in individuals with IL-10-592*A allele was 1.64 (95% confidence interval, 1.06-2.52) compared to individuals with the IL-10-592*C allele. No significant difference was observed in the genotype and allelic frequencies for the IL-10 A-592C polymorphism between patients with and without coronary artery lesions. The IL-10-592*A allele may be involved in the development of KD in Taiwanese children.
