Objective To assess the cost-effectiveness of different modes of the cataract operation. Methods Firstly, 291 cases of cataract inpatient were divided four groups according to operation modes (PHACO and ECCE) and the prices of intraocular lens (IOL) (high and low). Then the comparisons of inpatient cost, operation cost, postoperative VA, postoperative VF and QOL were made among four groups respectively. Finally, the cost-effectiveness of different cataract operation modes was analyzed by comparing the differences of their costs with the VA, VF and QOL improvement. Results There were significant differences in the above indicators among four groups in general (P 0.01). The VA improvement amount of PHACO was higher than that of ECCE whereas the VF and QOL improvement lower than those of ECCE. The price of IOL had no effect on the improvement quantity of VA, VF and QOL. When one unit amount of VA improvement wanted, the cost-effectiveness ratio of inpatient with PHACO and low-price IOL was the lowest. When one unit amount of VF and QOL improvement wanted, the cost-effectiveness ratio of patients with ECCE and high-price IOL was the lowest. When one unit amount of VA and QOL improvement wanted, the operation cost-effectiveness ratio of ECCE with low-price IOL was the lowest. And when one unit amount of VF improvement wanted, the operation cost-effectiveness ratio of ECCE with high-price IOL was the lowest. Conclusions There were cost differences among different cataract operation modes. The cost of PHACO was higher than that of ECCE. The ECCE mode and price of IOL were the main determinants of cost. The effects of improving VA and QOL by ECCE were better and the effect of improving VA by PHACO was better than by ECCE. The homemade or low price IOL had no influence on the cataractous operative effectiveness, but could decrease the operation cost. ECCE with low-price IOL was the optimal cost-effectiveness strategy and operation mode, especially for poor rural and remote areas.

Objective: To determine the contents of thromboxane (TXA_2) and prostacyclin (PGI_2) in optic nerves after acute intraocular hypertension injury so as to provide experimental data for the treatment of the clinical intraocular hypertension. Methods: A rabbit acute intraocular hypertension injury model was established by 90-min anterior chamber douche. Thirty adult rabbits were equally randomized into 5 groups: 4 intraocular hypertension injury groups (60 min, 90 min, 24 h and 48 h after intraocular tension normalization) and a normal control group. The eyes of all rabbits were removed and the homogenate of optic nerves was used to determine the contents of TXB_2 and 6-Keto-PGF_ 1?, and the metabolites of TXA_2 and PGI_ 2 by radioimmunoassay. Results: The contents of TXB_2 and 6-Keto-PGF_ 1? in the 60 min and 90 min groups were significantly higher than those of the normal control group (P

OBJECTIVE: To investigate the presence of vasculogenic mimicry in laryngeal squamous cell carcino- ma and explore its clinical significance. METHOD: The presence of vasculogenic mimicry and expression of endotheli- um-dependent vessel in 138 laryngeal squamous cell carcinomas cases were detected by the immunohistochemistry and tissue microarray. Metlab software was used to evaluate the relationship among vasculogenic mimicry, mi- crovessel density and clinic pathological parameters in laryngeal carcinoma. RESULT: We found vasculogenic mimicry in 32 (26.23%) of 122 laryngeal carcinoma samples. The mean of microvessel density is 12.61 per high-power field. The vasculogenic mimicry and expression of endothelium-dependent vessel were not significantly related to patient age or gender, tumor location, pathology grade, T stage or N stage (P > 0.05). However, the vasculo- genic mimicry and the mean of microvessel density were a little higher in patients older than 60, with poorly differ- entiated and patients with N₁₋₃ stage. Vasculogenic mimicry was positively correlatedwith microvessel density (r = 0.1927, P < 0.05). CONCLUSION Vasculogenic mimicry can occur in laryngeal carcinoma. Moreover, vasculogenic mimicry may be associated with recurrence and metastasis in laryngeal carcinoma.
