Objective To compare effects between laparoscopic operation and laparotomy in the treatment of acute colonic perforation, and to explore the safety of laparoscopic surgery. Methods A retrospective analysis was conducted on clinical data of 42 cases of acute colonic perforation treated in our hospital from January 2008 to December 2014, including 22 cases of laparoscopic surgery and 20 cases of traditional open surgery.The surgical treatment effects were compared between the two groups. Results As compared with the open group, the laparoscopic group had shorter operation time [(160.5 ±25.4) min vs.(210.3 ±45.6) min, t=-4.426, P=0.000], less amount of blood loss [(112 ±21) ml vs.(220 ±53) ml, t=-8.834, P=0.000], earlier enterostomy exhaust time [(4.2 ±1.2) d vs.(7.3 ±3.4) d, t=-4.016, P=0.000], less pulmonary infections [9.1% (2/22) vs.40.0%(8/20),χ2 =3.945, P=0.047], shorter total hospitalization time [(10.3 ±2.6) d vs.(15.6 ±2.4) d, t=-6.839, P=0.000], and lower costs of hospitalization [(2.26 ±0.45) ×104 yuan vs.(3.16 ±0.38) ×104 yuan, t=-6.966, P=0.000]. There was no significant difference in the perioperative mortality and wound infection rate between the two groups (P >0.05). Conclusion Laparoscopic surgery for acute colonic perforation has advantages of little surgical trauma, less bleeding, quick postoperative intestinal function recovery, low pulmonary infection rate, short hospitalization time, and low hospitalization costs, being an effective, safe, and feasible method worthy of clinical promotion.

Fraction F3-3-3 of glycosaminoglycan was isolated from the leftover bits of Bay scallop Argopecten irradiaus . Infrared spectra of F3-3-3 was similar to that of heparin. Agarose gel electrophoresis of this fraction was performed in the system of barbital buffer (0. 06 mol/L,pH 8. 6). It was found that F3-3-3 showed single band in the electrophoresis. Compared with the agarose gel electrophoresis of standard glycosaminoglycan, such as heparin, hyaluronic acid and chondroitin 6-sulfate, it indicated that the relative migration rate of the fraction was close to that of heparin.

Objective To study the relationship between the variation of the 20 exon of leptin receptor (LEPR) and lipid metabolism of the children with obesity. Methods Polymerase chain reaction-restricted fragments length polymorphism (PCR-RFLP) and polyacrylamide gel electrophoresis were used to analyze the variation of the 20 exon of the LEPR gene of the obesity group (120 obese children) and the control group (120 healthy children). Their serum triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), height, weight measured and the body mass index (BMI), fat percent (%fat) were calculated. Results 3 genotypes of the 20 exon of LEPR gene has been detected. Compared with the control group, the frequency of the gene variation at 3057 nucleotide G→A transversion is higher (P<0.05).The concentration of the serum TG, the level of BMI and %fat of the obese children with A/A genotype were higher than that with the G/G genotype (P<0.01),but the level of the serum HDL was lower (P<0.01).To the children with A/G genotype, only their TG level in serum are higher than that with the G/G genotype (P<0.05). Conclusion There is polymorphism at 20 exon LEPR gene in children with obesity, which may affect the lipid metabolism and the fat distribution. The obese children with A/A genotype should pay more attention to their diet to avoid some diseases followed obesity.
