Objective To compare surgical outcomes between laparoscopic high ligation and conventional procedure in the treatment of inguinal hernia.Methods High ligation of the hernial sac was performed in 94 patients with indirect inguinal hernia and communicating hydrocele between July 2002 and December 2004.Forty-four patients were treated laparoscopically by using a self-made hooked sledge-shaped needle(Laparoscopic Group),whereas conventional open procedure was conducted in 50 patients(Conventional Group).Results As compared with the Conventional Group,the Laparoscopic Group presented shorter operating time(18?5 min vs 27?8 min,t=-6.436,P=0.000),less postoperative analgesic requirement(5 patients vs 14 patient,?2 =4.017,P=0.045),shorter hospitalization length(3.2?1.2 d vs 7.3?1.9 d,t=-12.311,P=0.000),and higher total expenditure(2965.5?516.7 yuan vs 2389.7?372.3 yuan,t=-6.251,P=0.000).Conclusions Compared to conventional procedure,laparoscopic high ligation of hernial sac has advantages of minimal invasion,less pain,quicker recovery,shorter hospitalization,and better cosmetic results.It is an ideal procedure for treating pediatric indirect inguinal hernia and communicating hydrocele.

Objective To examine the effect and mechanism of different targets of glucose control on liver damage in rats with sepsis .Methods The rat sepsis model was established by cecal ligation and puncture (CLP) .Forty Sprague‐Dawley rats were randomly divided into five groups (eight rats to each group):sham operation (sham group) ,sepsis (CLP group) ,glycemic control A group (glucose target 4 .6‐6 .1 mmol/L ) ,glycemic control B group (glucose target 6 .2‐8 .3 mmol/L ) and glycemic control C group (glucose target 8 .4‐10 .0 mmol/L) .The animals were sacrificed 12 hours after CLP .Venous blood was sampled for testing alanine transaminase (ALT ) , aspartate transaminase (AST ) and free fatty acid (FFA ) . Peroxisome proliferator activated receptor‐α (PPAR‐α) and liver carnitine palmitoyltransferase 1 (CPT‐1 ) protein were determined by immunohistochemistry .The pathological changes of liver tissue was observed under an optical microscope .Results The levels of ALT ,AST and FFA in venous blood and the pathological tissue injury score in sepsis groups were higher than those in sham group and all glycemic control groups (P<0 .05) .However ,the level of these markers significantly decreased in group A than those in group B or group C (P<0 .05) ,and lower in group B than those in group C (P< 0 .05) .PPARα and liver CPT‐1 expression levels were lower in sepsis group than those in sham group and all glycemic control groups except group C (P>0 .05) .The levels of PPARαand liver CPT‐1 were significantly higher in group A than in group B or group C (P<0 .05) ,and lower in group C than in group B(P<0 .05) .Conclusions The lowest target of glucose control(4 .6‐6 .1 mmol/L)shows better protective effects on liver damage in rats with sepsis ,the mechanism of which may be related to upregulation of PPARα and liver CPT‐1 expression .
