  • Association of -2548 G/A Polymorphism of Leptin Gene with Cholesterol Gallstones

    ObjectiveTo explore the relationship between the -2548 G/A functional polymorphism in the 5′ promoter region of the leptin gene and gallstones. Methods The -2548 G/A polymorphisms of leptin gene were determined by polymerase chain reactionrestriction fragment length polymorphism technology (PCRRFLP) in 118 patients with cholesterol gallstones and 53 normal control subjects. Then the allele and genotype distribution were studied. Results The distribution of leptin2458 G/A in two groups was statistically significantly different: the genotype frequency of AA+GA of patients in gallstone group was higher than that in control group (χ2=4.251, P=0.039). AA+AG genotype had 2.813 times greater risk for gallstone disease compared with GG genotype (OR=2.813, 95% CI=1.020-7.757). Allele frequency distribution in the two groups was different: the allele frequency of A of patients in gallstone group was higher than that in control group (χ2=5.791, P=0.016). The risk of gallstone disease in the A alleles carriers was 1.777 times as higher as the carriers of G alleles (OR=1.777, 95% CI=1.110-2.844). ConclusionThe -2548 G/A polymorphism in the 5′ promoter region of leptin gene is significantly correlated with the gallstones. The A alleles of leptin may be a genetic factor which contributes to individual susceptibility for gallstone, while the G alleles of leptin may be a genetic factor that prevents people from gallstone.

  • Measurement and Significance of Serum Nitric Oxide Level in Patient with Obstructive Jaundice and Renal Dysfunction

    ObjectiveTo study the change and significance of the serum nitric oxide (NO) level in patient with obstructive jaundice complicated with renal dysfunction. MethodsThe level of NO, BUN, Cr in serum and the activity of NOS in 25 patients with obstructive jaundice and renal dysfunction and 26 healthy adults was studied.ResultsThe patients’ serum NO level and the activity of NOS were significantly lower than those in the control group(P<0.01),whereas the serum BUN and Cr levels were significantly higher than those in control group(P<0.01). The linear correlation analysis showed that the serum NO had a negative correlation between serum BUN and Cr level (P<0.01). ConclusionThe patients with obstructive jaundice and renal dysfunction may lead to the decrease of serum NO level. NO may have some protective effects to the renal function during obstructive jaundice.

  • Value of Magnetic Resonance Cholangiopancreatography on Prevention of Complications in Laparoscopic Cholecystectomy

    ObjectiveTo evaluate the value of magnetic resonance cholangiopancreatography (MRCP) on prevention of the complications in laparoscopic cholecystectomy (LC). MethodsThe clinical data of 1 079 patients underwent LC from January 2006 to June 2010 in this hospital were retrospectively analyzed. According to the use of MRCP or not in the different period, the patients were divided into nonMRCP group (n=523) and MRCP group (n=556). The occurrence of bile duct injuries (BDI) and retained common duct stone (RCDS) were compared between two groups. ResultsConversion to open surgery was performed in 35 cases in nonMRCP group and in 41 cases in MRCP group. The intraoperative and postoperative BDI were found in five patients and RCDS were found in 27 patients in nonMRCP group, and those were not found in patients in MRCP group. The differences of BDI and RCDS of patients were significant between two groups (P=0.026 and P=0.000). In nonMRCP group, 23 of 55 patients were found common bile duct stones by intraoperative cholangiography. Common bile duct stones were found by intraoperative cholangiography other than preoperative MRCP in three patients in MRCP group, while another three patients did not find common bile duct stones by intraoperative cholangiography although preoperative MRCP suggested. By MRCP, double gallbladders were found in one patient, Mirizzi syndrome in eight patients, variant cystic duct in 34 patients, accessory hepatic duct in 28 patients, and complicating common bile duct stones in 27 patients in MRCP group, the diagnostic accuracy of those were 100%, 87.5%, 94.1%, 89.3% and 88.9%, respectively. ConclusionPreoperative MRCP is helpful to prevent BDI and RCDS for the patients with LC.
