Objective To investigate the influence of abaI expression on acinetobacter baumannii biofilm formation.Methods Acinetobacter baumannii strain S isolated from bums patients was collected for the study,while the standard strain ATCC19606 was served as the control.At 6,24 and 48 hours,the gene expressions of abaI,pgaA,pgaB and pgaC were detected by real-time fluorescent quantitative PT-PCR,secretion of N-acyl-homoserine lactones (AHLs) by biological sensor and biofilm formation by MTT method.Results (1) Gene expressions of abaI,pgaA,pgaB and pgaC at 6 hours were 8.63 ±5.93,1.98 ± 1.93,1.01 ± 1.32 and 2.67 ± 3.46 respectively,which showed a quick increase at 24 hours (22.81 ± 17.60,5.13 ± 4.32,5.66 ± 3.97,11.97 ± 7.75 respectively),followed by a rapid decline in 48 hours (3.43 ± 0.88,1.30 ± 0.24,3.01 ± 3.00,3.02 ± 3.29 respectively).Gene expressions of pgaB and pgaC at 6 hours and that of pgaA and pgaC at 48 hours revealed statistically significant differences from those at 24 hours (P ＜ 0.05).(2) AHLs showed a level of 18.49 ± 11.03 at 6 hours,reached a peak of 52.23 ± 15.95 at 24 hours,then descended to 5.53 ± 0.94 at 48 hours.AHLs level at 24 hours showed statistically significant difference from that at 6 hours and 48 hours (P ＜ 0.05).(3)Biofilm formation at 24 hours and 48 hours was 2.83 ±0.44 and 2.71 ±0.15 respectively,far higher than that at 6 hours (0.49 ± 0.11,P ＜ 0.05).(4) In the correlation analysis among AHLs,biofilm formation and gene abaI,pgaA,pgaB and pgaC expressions,significant positive correlation was found between abaI and pgaA and between AHLs and pgaC expression (P ＜ 0.05).Conclusion Acinetobacter baumannii may regulate gene expressions of pgaA and pgaC responsible for biofilm formation to adjust to the external environment by means of changing abaI gene expression and AHLs secretion.

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

OBJECTIVE:To investigate the effects of NOS1AP rs12742393 A/C gene polymorphism on lipid-regulating re-sponse of rosuvastatin calcium. METHODS:Two hundred and tuirty six patients with coronary heart disease(CHD)were selected from cardiology department of our hospital during Jan. 2014-Jun. 2015,and then given rosuvastatin calcium and other symptomatic treatment for 12 weeks. Polymorphism of NOS1AP rs12742393 A/C was detected by PCR-RFLP. The levels of TG,TC,HDL-C and LDL-C were detected by photoelectric colorimetry before treatment and 4,12 weeks after treatment. The serum relationship of genotype with the level of blood lipid was analyzed. RESULTS:Among 236 CHD patients,there were 131 cases of AA genotype (55.5%),98 cases of AC genotype(41.5%) and 7 cases of CC genotype(3.0%);genotype and allele frequencies met the Har-dy-Weinberg balance(P>0.05). There were 132 patients with normal blood lipid and 104 patients with hypercholesterolemia;there was statistical significance in genotype and allele frequencies (P<0.05). Among 104 CHD patients with hypercholesterolemia be-fore treatment,there was no statistical significance in the levels of TG,TC,LDL-C and HDL-C between AA genotype and AC+CC genotype(P>0.05). 4th and 12th week after treatment,the levels of TG,TC and LDL-C in different genotypes were all de-creased significantly;4th week after treatment,the level of LDL-C in AC+CC genotype was significantly lower than AA genotype, and the change compared to before treatment was significantly more than AA genotype,with statistical significance (P<0.05). There was no statistical significance in the level of HDL-C among different genotypes compared to before treatment;there was no statistical significance in the levels of TG,TC and HDL-C 4th,12th week after treatment and their changes compared to before treatment between AA genotype and AC+CC genotype;there was no statistical significance in the level of LDL-C 12th week after treatment and their changes between AA genotype and AC+CC genotype(P>0.05). CONCLUSIONS:NOS1AP rs12742393 A/C gene polymorphism is associated with CHD complicated with hypercholesterolemia;the C allele of NOS1AP rs12742393 may strengthen the response of CHD patients with hy-percholesterolemia to rosuvastatin calcium through influencing the level of LDL-C.

Methods including stimulation, cauterization, of nuclei and measurement of pain threshold were used to clarify the role of paraventricular nucleus of hypothalamus (PVH) in pain regulation. Results showed that electrical or L-glutamate sodium stimulation of PVH could elevate the pain threshold in the rat dose-dependently, electrical cauterization of PVH could reduce the pain threshold; and removal of the pituitary gland could not influence the effect of L-glutamate sodium on pain threshold. These results suggest that PVH may play an important role in pain regulation.

The 54th ASH annual meeting should be considered as a revolution for treatment of lymphoma.Keep away from chemotherapy will not be just a dream,it based on the deep understand of lymphoma genesis and quick development of different targeted agents.The typical examples are the dramatic novel agents targeting B cell receptor signaling pathway and microenvironment.There combination,such as R-square regimen,showed unbelievable efficacy in indolent B cell lymphomas and tiny side effects.It is sure that therapy breakthroughs in aggressive B cell lymphomas and T/NK cell lymphomas are in the very near future.

Chronic activation of the B-cell antigen receptor (BCR) signaling pathway performs a critical function in the pathogenesis of numerous subtypes of B-cell malignancies and transforms normal cells into malignant cells. Bruton tyrosine kinase (BTK) is a member of the TEC family of tyrosine kinases and is a key regulator of the BCR signaling pathway. BTK inhibition has emerged as a new target for therapeutic intervention in B-cell malignancies. This review summarizes recent developments of BTK inhibitors in B-cell malignan-cies.
