Objective To investigate the association between the tumour necrosis factor-α-863(TNF-α-863) polymorphism and gout in Han population from the city of Tangshan.Methods We recruited 80 gout patients and 80 healthy individuals into this study.The polymorphisms of TNF-α-863 site were analyzed by polymerase chain reaction-ligase detection reaction(PCR-LDR).The frequencies of different TNF-α-863 genotypes/alleles were analyzed in the gout group and the control subjects.Results No significant differences were observed in the genotype frequencies(x2=2.8807,P=0.0897) and allelic frequencies(x2=4.2646,P=0.1187) of TNF-α-863 site in the comparison between gout and control groups.Conclusion The result of our study suggests that the polymorphism of TNF-α-863 site may not related to gout in Han population in Tangshan.

OBJECTIVETo explore the effect of surgical treatment on complex acetabular fractures.

METHODSThe data of 46 patients (38 males and 8 females, aged 16-75 years, mean equal to 38.5 years) with complex acetabular fractures, who were admitted to our hospital from January 1998 to December 2005, were analyzed retrospectively in this study. According to Letournel rules, posterior wall and posterior column fractures were found in 11 patients, transverse and posterior wall fractures in 13, T-type fracture in 4, both columns fracture in 10, and anterior column and posterior transverse fracture in 8. The choice of surgical approach was based on the individual fractures, which included ilioinguinal approach in 5 patients, Kocher-Langenbech approach in 7, combined approach in 26, and extended iliofemoral approach in 8.

RESULTSAll the patients were followed up for 3.5 years averagely. The clinical outcomes were analyzed with Harris hip score and radiography. In 36 patients (78.3%), the surgical procedure was successful (Harris hip score more than 80 points). The rate of excellent and good was about 86%.

CONCLUSIONSThe keys to increase the effectiveness of surgical treatment on acetabular fractures are correct preoperative classification of fractures and choices of appropriate surgical approach and time.

OBJECTIVETo evaluate the effects of infant formula containing palm oil on the nutrient absorption and defecation in infants.

METHODSA search in Cochrane Library, PubMed, OVID, Springer, China National Knowledge Infrastructure, Vip Chinese Periodical Database, Wanfang Chinese Periodical Database and Chinese Bio-medicine Database was performed to identify relevant English and Chinese language articles between January 1990 and March 2009. Two reviewers independently performed data extraction and appraised using Jadad instrument. Double data were input and analyzed by software of Review Manager 4.2 recommended by Cochrane Collaboration. Intestinal nutrient absorption, electrolyte content of fecal excretion, in vivo calcium deposition, and defecation were included as the target outcomes. These outcomes were evaluated as the combined standardized mean difference (SMD) and relative risk (RR) value and 95% CI of them.

RESULTSThirteen articles were included. Three articles meeting inclusion criteria were analyzed for the effects between infant formula containing palmitic acid at the Sn-2 positions and palmitic acid at the Sn-1, 3 positions; five articles were analyzed for the effects between infant formula containing palmitic acid at the Sn-1, 3 and without palmitic acid; another five articles were analyzed for the effects between infant formula containing palmitic acid at the Sn-2 positions and without palmitic acid. Absorption of fat and calcium was higher, the Ca(2+) of fecal excretion was lower when the infant formula provided palmitic acid at the Sn-2 positions or without palmitic acid than that determined when formula containing palmitic acid at the Sn-1 and Sn-3 positions was given (P < 0.01). The bone mineral content (BMC) and bone mineral density (BMD) increased at 3, 6 months when the infant formula without palmitic acid as compared with using the formula containing palmitic acid at the Sn-1 and Sn-3 positions (P < 0.01). The formation of calcium soaps in stool was reduced, the BMC increased when the infant formula provided palmitic acid at the Sn-2 positions as compared with using the infant formula without palmitic acid (P < 0.01). The incidence of soft stools was higher, and the incidence of hard stools was lower when the infant formula provided palmitic acid at the Sn-2 positions or without palmitic acid than that when formula containing palmitic acid at the Sn-1 and Sn-3 positions was used (P < 0.01).

CONCLUSIONAbsorption of fat and calcium was lower, the Ca(2+) of fecal excretion was higher, the BMC was reduced, the incidence of hard stools increased when the infant formula provided the palmitic acid at the Sn-1 and Sn-3 positions as compared with using formula contained palmitic acid at the Sn-2 positions or without palmitic acid. However, this conclusion should be used cautiously because of the limited quality of studies included into the analysis.
