Objective To analyze the value of open tension -free hemiorrhaghy ( OTFH) and laparoscopic totally extraperitoneal prosthesis ( LTEP) repair in patients with bilateral inguinal hernia .Methods A retrospective method was used to compare the clinical data of 115 patients with bilateral hernias , of which 61 cases received LTEP and 54 cases underwent OTFH , from June 2011 to December 2013, in our hospital .Results The mean operative time of LTEP group (88.2 ±15.6 min) was longer than the OTFH group(75.7 ±21.6) min (p<0.05).The dura-tion of hospitalization in LTEP group(2.6 ±1.1) day was shorter than OTFH group(4.2 ±2.1) d (p<0.05).Hos-pitalization expense of LTEP group (12 012.0 ±2 325.2) yuan was higher than the OTFH group (9 291.3 ±2 010.1) yuan (p<0.05).The incision pain by VAS points was gradually decreased in 24 hours, 48 hours, 72 hours after op-eration, and LTEP group was significant lower than OTFH group in the same time point .In LTEP group 3 case had laceration of peritoneum but turn to no other prosthesis , and 2 cases had acute urinary retentions .11 acute urinary re-tentions occurred in OTFH group , and 2 cases had chronic pain in inguinal area and 1 cases of fat liquefaction .No recurrence was found during a follow -up period of 6 to 24 months in both of 2 groups .Conclusion Both LTEP and OTFH are safe and accessible techniques for patients with bilateral inguinal hernia .OTFH is feasible, and has short process and low cost which is suitable for primary hospitals to carry out .OTFH has the advantages of little trauma , faster postoperative recovery and less complications which is worth promoting in future .

β thalassemia is a hereditary hemolytic disease caused by the defect of β globin gene. Transfusion-dependent β thalassemia patients need long-term blood transfusion to survive, and a series of systemic and ocular complications will occur in the disease itself and long-term blood transfusion. Retinal blood vessel density decreases, retinal thickness thinned and elastic pseudoxanthoxanoma syndrome are found in fundus due to long-term anemia and side effects of iron chelating agent. At present, there are few reports about eye changes in thalassemia patients, and the cognition is relatively scarce. Therefore, it is necessary to be vigilant for physicians, deeply explore the cause and symptomatic treatment, combined with individual disease characteristics, to provide a more scientific and accurate plan for clinical treatment.

Beta-thalassemia major(β-TM)is an inherited disease caused by a defect in the synthesis of globin. The disease requires long-term blood transfusion and iron chelator treatment, which can cause various secondary changes in the body and eye tissues. Compared with normal peers, β-TM patients will show changes in the eye such as steeper corneal curvature, shallower anterior chamber, increased lens thickness, shorter axial length, and reduced tear secretion. At the same time, nutritional deficiencies and the use of iron chelator drugs will increase the risk of complicated cataract and retinal degeneration, thus affecting the quality of life of β-TM patients.This article combines relevant domestic and foreign literatures to explore and review the changes in the eye of β-TM patients, with a view to providing valuable insights for clinical practice.
