Objective:To explore the correlation between lower gastrointestinal tract symptoms and diabetic retinopathy and lower extremity artery disease in patients with type 2 diabetic mellitus.Methods:The clinical data of 128 patients with type 2 diabetic mellitus from August 2016 to March 2018 in Central Hospital of Shengli OilField were retrospectively analyzed. The general clinical data and laboratory indexes were recorded. The score was evaluated by lower gastrointestinal symptoms rating scale (LGSRS). Patients with the LGSRS score ≥6 scores were as positive group, and those with LGSRS score<6 scores were as negative group. Fundus photography and ultrasonic scanning of lower extremity artery disease were performed for each patient. The correlation between LGSRS score and diabetic retinopathy, lower extremity artery disease was analyzed by Logistic regression.Results:Positive group had 66 cases, and negative group had 62 cases. The age, duration of diabetic, LGSRS score and incidence of diabetic retinopathy in positive group were significantly higher than those in negative group: (64.24 ± 10.43) years vs. (59.57 ± 12.50) years, (14.67 ± 1.28) years vs. (10.98 ± 1.25) years, (8.65 ± 2.38) scores vs. (2.77 ± 1.49) scores and 98.48% (65/66) vs. 69.35% (43/62), and there were statistical differences ( P<0.05 or<0.01). There were no statistical difference in gender, body mass index, glycated hemoglobin, fasting blood glucose, 2 h postprandial blood glucose, triglyceride, total cholesterol and incidence of diabetic retinopathy between 2 groups ( P>0.05). After adjusting for age, duration of diabetic, glycated hemoglobin, fasting blood glucose, triglyceride and total cholesterol, the LGSRS score showed positive correlation with diabetic lower extremity artery disease ( OR = 1.174, 95% CI 1.065 to 1.470, P = 0.001), but there was no correlation between LGSRS score and diabetic retinopathy ( P = 0.313). Conclusions:In patients with type 2 diabetes mellitus, lower gastrointestinal tract symptoms has positive correlation with diabetic lower extremity artery disease, and no correlation with diabetic retinopathy. It suggests that there may be a common pathological mechanism between lower gastrointestinal tract symptoms and diabetic lower extremity artery disease.

Immobilized penicillin acylase was used for bioconversion of penicillin G into 6-APA in aqueous two-phase systems consisted of a light-sensitive polymer PNBC and a pH-sensitive polymer PADB.Partition coefficients of 6-APA was found to be:about 5.78,in the presence of 1% NaCl.Enzyme kinetic showed that reaction reached equilibrium at 7h or so.The 6-APA mole yields were 85.3%(pH 7.8,and 20 ℃) and this value was about 20%higher than control in reaction of single aqueous phase buffer.Partition coefficient of penicillin G(Na) washardly changeable,while partition coefficient of product,6-APA and phenylacetate acid was significantly changeable.Reason is due to Donnan effect of phase systems andhydrophobicity of products.The change of partition coefficients of products also affects bioconversion yield of products.In the aqueous two-phase systems,substrate,penicillin G,products 6-APA and phenylacetate acid are biased in top phase,while immobilized penicillin acylase is completely partitioned in bottom.Substrate,penicillin G enters into bottom phase,and it is catalyzed into 6-APA and phenylacetate acid,then the products enter into top phase.Finally,inhibition of substrate and products is removed to result in improvement of products yield.Moreover,immobilized enzymehashigher efficiency than immobilized cells and occupy smaller volume.Comparing with free enzyme,immobilized enzymehashigher stability,longer use life,completely partitioned in bottom phase and recycle.Bioconversion in two-phase systems using immobilized penicillin acylase showed outstanding advantage.The light-sensitive copolymer forming aqueous two-phase systems could be recovered by laser radiation at 488 nm or filtrated 450 nm light,while pH-sensitive polymer PADB could be recovered by isoelectric point(pH 4.1).The recovery of the two copolymers was 95%~99%.

OBJECTIVETo explore the significance of combined therapy of arsenic trioxide (As2O3) and all-trans retinoic acid (ATRA) in acute promyelocytic leukemia (APL).
METHODSRetrospective study of 80 APL patients was performed and the complete remission (CR), the recovery time of peripheral hemoglobin and platelet, the early mortality, and the adverse reaction rates were analyzed between the ATRA group and the ATRA combined As2O3 group (combined group).
RESULTSCR rate of the combined group and the ATRA group was 91.7% and 87.5% respectively, which showed no significant difference; time of reaching CR, hemoglobin recovery, and platelet recovery for the combined group were 28.0 +/- 7.8 days, 22.36 +/- 8.72 days and 19.38 +/- 9.52 days respectively, while those were 47.7 +/- 10.9 days, 28.40 +/- 8.95 days and 28.03 +/- 7.29 days for the ATRA group, which suggested a significantly shorter period of the combined group of achieving recovery. With 7.1% compared to 13.2%, the early mortality of the combined group seemed lower than that of the ATRA group but with no significance observed (P>0.05). The adverse reaction rates of the two groups also lacked any significant difference (P>0.05).
CONCLUSIONCompared with using ATRA alone, the combined therapy of AS2O3 and ATRA was dominant in achieving CR and recovery for APL. Besides, the combined therapy carries the promise of reducing the early mortality with no aggravation of the adverse reaction.
