Objective To explore the effect of endoscopic transnasal dacryocystorhinostomy(ET-DCR) by suture in the treatment of acute dacryocystitis(AD) as early as possible.Methods The clinical data of 32 patients with unilateral AD who underwent ET-DCR by suture as early as possible were retrospectively analyzed.Results All patients presented clear anatomic structure,intraoperative hemorrhage increased in 3 cases,swelling and pain was rapidly relieving in all patients in the first day of postoperation,the mean resolution time of congestion and swelling in the middle canthus was average 3 days(range 1-6 days),no spread of infection occurred,no facial scar appeared in all patients except one case of abscess rupture.Complete complaint relief in 26 cases,slight epiphora presented in 6 patients who confirmed for lacrimalduct obstruction and cured by intubation,and all ostial patency with no AD recurrences at the mean follow-up of 2 years (range 12 months-5 years).Conclusion ET-DCR by suture as early as possible can be used to cure acute dacryocystitis and it is effective safe and economy.

Objective To investigate the clinical value of endoscopic transnasal dacryocystorhinostomy ( ET-DCR) by suture techniques.Methods 85 patients of 98 eyes with chronic dacryocystifis were randomly divided into the two groups:control group ( without suture) and observation group ( by suture) .All cases were followed up for more than 12 months.The cure rates and occurrence of granulation tissue were compared between the two groups. Results The cure rate of the observation group ( 96.00%, 48/50 ) was higher than that in the control group (81.25%,39/48) (χ2 =5.35,P<0.05). During process of following up,the occurrence of granulation tissue at the ostium margins accounted for 14.00%(7/50) in the observation group and 31.25%(15/48) in the control group (χ2 =4.19,P<0.05).Conclusion ET-DCR by suture techniques reduces the formation of granulation tissue and improves the cure rate.Especially, ET-DCR by suture techniques for the small lacrimal sac of patients may have special advantages.

Objective To investigate the affect of body positions on biochemical indexes. Methods By autogenous contrast and cross matched survey, 107 volunteers divided into 3 season patches of winter, spring and summer, blood samples were drawn from the same part in both standing and lying positions。From19 persons, blood samples were collected respectively after standing and sitting for 15 min, lying for 15 min and 30 min and then sitting for another 15 min。 The blood samples were analyzed for 32 biochemical indexes on analyzer。Results 25 biochemical indexes in sitting position were significantly different from those in lying position (P0。05)。Conclusions Changing body position can result in obvious physiological variation of 28 biochemical indexes, particularly of those related to protein. Such result may lead to abnormality in some marginal values. It suggests body position should not be neglected in analyzing laboratory data.
