Objective Because of high incidence rate of complicated postoperative abdominal infections in abdominal injuries and difficulty in their clinical diagnosis and treatment,this article aimed to investigate the mechanism and the surgical tactics for this kind of complication.Methods Totally 48 abdominal-injured cases of postoperative complicated abdominal infections in our hospital from July 2005 to December 2010 were reviewed.These patients (Male 30,Female 18) aged 16-70 (mean 38) years.There were 20 cases of simple abdominal injuries,and 28 cases of multiple injuries ( ISS 16 - 52,mean 24.42).The complicated postoperative abdominal infections included abdominal incision infections (25cases),intra-abdominal infections( 18 cases) and retroperitoneal infections(5 cases).Forty cases were transferrted from other hospitals to our hospital 2 - 76 days after trauma.16 of which underwent exploratory laparotomy at other hospitals after injury,and 8 cases were directly transferred to our hospital after injury.Results All patients finally had a definite diagnosis by abdominal checking(26 cases),paracentesis(5 cases),ultrasound and CT scan ( 12 cases),and PET/CT scan (5 cases)in our hospital,and were confirmed by cultiure of pathogenic bacteria.The treatment included vacuum sealing drainage (VSD) (25 cases),percutaneous imaging- guided abdominal abscess drainage(13cases) and re-laparotomy ( 10 cases).Successfull treatment was achieved in 46 patients,death in 2 patients.The causes of death consisted of 1 case of severe craniocerebral injury,1 case of MODS.Conclusions Complicated abdominal infections often occurs after the operations of abdominal injuries.attentively abdominal checking,paracentesis,and CT scan repeatedly were proofs to benefit the finally diagnosis.VSD therapy is a simple and effective method for abdominal incision complication,and dynamic CT scan and prompt exploratory laparotomy can improve patients' prognosis.

Rectal diverticulum is rarely seen in clinical practice.Perforation or rupture of rectal diverticulum with symptoms and signs of acute diffuse peritonitis makes it easily be misdiagnosed as appendicitis,rectal neoplasms,intestinal obstruction and other abdominal diseases.In this article,a retrospective analysis of the clinical data of one patient with extraperitoneal pneumatosis caused by perforation of rectal diverticulum was performed to investigate the diagnosis and treatment of the disease.

OBJECTIVETo assess the association of single nucleotide polymorphisms (SNP) rs547984, rs540782, rs693421 and rs2499601 of Zona Pellucida Glycoprotein 4 (ZP4) gene with primary open-angle glaucoma (POAG) among ethnic Han Chinese from Sichuan Province.

METHODSA dye terminator-based SNaPshot method was used to genotype 336 patients with POAG and 768 healthy controls.

RESULTSNo significant difference was detected in allelic frequencies of rs547984, rs540782, rs693421 and rs2499601 between the two groups (P>0.05). Haplotypic analysis showed a significant difference in G-G-A-G haplotype formed by the 4 SNPs between the POAG and the control groups (P<0.05).

CONCLUSIONZP4 gene SNPs rs547984, rs540782, rs693421, rs2499601 are not associated with POAG among ethnic Hans from Sichuan.
