The study was carried out to evaluate the contents of common biogenic amines, microbial community diversity and physicochemical indicators of seven samples of fermented liquid soybean products and seven samples of fermented solid soybean products. The results showed that the total amount of biogenic amines in defatted soy sauce, steamed fish soy sauce and oyster reduced salt soy sauce were all higher than 8 000 mg/L and significantly higher than those in the other samples (P < 0.05). The pH and Kjeldahl nitrogen contents of the samples were negatively correlated with the total content of biogenic amines, while water activity (factor loading 0.413), total acid content (factor loading 0.399) and salinity (factor loading 0.330) had a greater positive effect on the production of biogenic amines. Pseudomonas spp. and Bacillus spp. were positively and negatively correlated with the content of biogenic amines, respectively. The results of the study provide a theoretical basis for the development of relevant standards.

AIM: To observe the clinical effect of trabeculectomy combined with dexamethasone iontophoresis in the treatment of acute angle-closure glaucoma(PACG)with diabetes mellitus.METHODS: Totally 42 eyes of 42 patients with acute PACG combined with diabetes in our hospital were selected and divided into trabeculectomy combined with iontophoresis group(group A)and trabeculectomy combined with peribulbar injection of methylprednisolone group(group B)according to different ways of controlling inflammation after surgery. Intraocular pressure, anterior chamber inflammation and complications before and after surgery were compared between the two groups.RESULTS: The intraocular pressure of the two groups after surgery was significantly improved compared with that before surgery, and the difference was statistically significant(PP>0.05). In terms of complications, group A was significantly superior to group B.CONCLUSION: Trabeculectomy combined with dexamethasone iontophoresis or peribulbar injection of methylprednisolone can effectively control postoperative intraocular pressure and anterior chamber inflammation in patients with acute angle-closure glaucoma complicated with diabetes mellitus. Among them, the effect of combined dexamethasone iontophoresis in reducing complications is better and patients suffer less pain.
