Objective To explore the clinical effects of phacoemulsification with intraocular lens implantation for cataract patients who have had glaucoma and have undergone trabeculectomy before.Methods Phacoemulsification with intraocular lens implantation was performed on 33 patients(38 eyes)with cataract after trabeculectomy.The postoperative visual acuity,intraocular pressure(IOP),filtering bleb,corneal endothelium and complications were observed.Results No posterior capsular rupture occurred and all the lenses were inserted into the capsular bags.Follow up for 3 months at least.The correct visual acuities were≥4.7 in 30 cases(78.9%),≥5.0 in 6 cases(15.8%).Postoperatively,the IOP of all eyes was below 20mmHg and there was no change in the filtering bleb.The loss rate of the corneal endothelial cells was 15.07%after the operation.The density of the postoperative corneal endothelial cells was statistically significant different from those of the preoperative(t=4.582,P＜0.01).The complications occurred more than that of regular phaeoemulsification.Conclusions Phacoemulsification is convenient and effective in patients with cataract after trabeculectomy.The incision should be made without damaging the filtering bleb.The surgery requires skillfully and actively enlarging the small pupils and protecting the corneal endothelium.

Objective To investigate the effect of rosiglitazone on the expression of platelet CD40 ligand (CD40L) in insulin-resistant rats, and to further determine the relationship between CD40L and insulin resistance. Methods 60 healthy male SD rats [(200±20)g] were randomly divided into 4 groups: control group (C), high fat group (HF), low dose rosiglitazone group (LR) and high dose rosiglitazone group (HR). Rats in group C were fed normal chow diet, and the others were given high fat chow diet. After 12 weeks, high dose of rosiglitazone (10mg/kg) was given to rats in group HR and low dose of rosiglitazone (5 mg/kg) was given to rats in group LR for 4 weeks. Rats in group HF and group C were given 0.9% sodium chloride solution. The level of sCD40L was measured by ELISA and the expression of platelet membrane CD40L was detected by immunoprecipitation and Western blot. The insulin resistance (IR) index was calculated by homeostasis model assessment (HOMA). Results HOMA-IR, sCD40L level and platelet membrane CD40L expression were higer in group HF than in group C (9.8±3.2 vs. 5.9±1.7, 367.3 ±35.3 vs. 232.3±120.6, 2.1±0.4 vs. 1.4±0.2, respectively, all P<0.05). Compared with the group HF, HOMA-IR, sCD40L level and platelet membrane CD40L expression were obviously decreased in group HR(5.4±1.1, 276.9±54.0, 1.4±0.3, respectively, all P<0.05), and there were no significant differences in HOMA-IR, sCD40L level and platelet membrane CD40L expression between group HF and group LR (P>0.05). Conclusions In insulin-resistant rats, the level of sCD40L and the expression of platelet membrane CD40L were higher. After treatment with high dose of rosiglitazone, sCD40L level and platelet membrane CD40L expression were decreased with the improvement of insulin resistance.

Several signaling pathways are involved in clonal proliferation of lymphoma cells and disease progression. It has been shown that cyclic adenosine monophosphate (cAMP) signaling pathway, as an important intra-cellular messenger delivery system, is related to modulation of multiple physiological processes including cell prolifer-ation, secretion, metabolism and apoptosis. Manipulating the cAMP signaling pathway can induce cell cycle arrest and apoptosis of various malignant lymphoid cells, which involves mitochondria-dependent apoptosis and cAMP-modulated protein kinases as well as changes of intracellular mediators. In-depth research and analysis of cAMP-induced apoptosis in lymphoma cells would provide potential targets and possible therapeutic means for the treatment of lymphoma.

Sulphur mustard (SM) is a corrosive alkylating agent that is likely to be absorbed in vivo through the lungs,eyes and skin into internal organs. SM not only can produce its peculiar cytotoxic?ity thought to be mediated by the alkylation of DNA,protein and nucleic acids,but is a strong mutagen and carcinogen. However,whatever the way SM poisoning occurs,lungs are the most vulnerable, and early death is mainly carused by both the acute respiratory distress syndrome and pulmonary infec?tion. In this review,we analyzed SM-induced lung injury mechanisms.
