ABSTRACT
Objective To compare clinical efficacy between microendoscopic discectomy (MED) and open discectomy (OD) in the treatment of patients with lumber intervertebral disc herniation (LIDH).Methods 116 cases of LIDH who were given surgical treatment were selected as research subjects to retrospectively analyze their clinical data.Then,these cases were divided into MED group (n=54) and OD group (n=62) according to operation type.The curative efficacy,operation situation and incidence of complications were compared.Results All patients' operations were successful.After the one-year follow-up,the MED group had an excellent and good rate of 96.3％,which was statistically same with that of 93.5％ in the OD group (P ＞0.05) In comparison with the OD group,MED group had a statistically shorter operation time,less bleeding volume in the operation,shorter length of incision and shorter rest time on bed after operation (all P＜0.05).After operation,there's no case of severe complication,and the incidence of complications between the two groups was statistically same (P＞0.05) Conclusions MED and OD are both effective operations for LIDH,which have high excellent and good rate.But in comparison with OD,MED has advantages of less damage and faster recovery.
ABSTRACT
OBJECTIVE@#To study the relationship between fibrinogen level and pathogenesis of sudden sensorineural hearing loss(SSHI.).@*METHOD@#Fifty patients (55 ears) with SSHL within 7 days of the onset were studied: a control group was consist of 50 normal-hearing people who were individually matched on a pairwise basis according to the same gender and age. Both the patients and the normal people were tested for the parameters of hemorheology, blood biochemistry, whole blood cell count and clotting function.@*RESULT@#Fibrinogen level and plasma viscosity in patients with SSHL were significantly higher than that in control subjects. Prothrombin time and activated partial thromboplastic time were significantly less in the patients group than that in the control group (P 0.05).@*CONCLUSION@#Elevated plasma fibrinogen may be a major pathogenesis of SSHL. An increase in plasma fibrinogen level may lead to elevated plasma viscosity. All these may promote a prothrombin or hypercoagulable state and impair blood perfusion of cochlea.
