Innate lymphoid cell is a type of newly discovered innate immune cell , which can function as adaptive T cells . Based on the transcription factors and the expression of effector cytokines , innate lymphoid cells can be categorized into three sub-groups:ILC1, ILC2 and ILC3.The inflammatory factors these produced by ILC play an important role in the development of inflamma -tory bowel disease (IBD), but ILC3 can secrete IL-22, which promotes the restoration of intestinal epithelial cells .Exploring the func-tion of ILC has a great significance in the treatments of IBD .This article reviews their phenotype , function and also relationship with IBD.

Objective To analyze and compare the clinical and laboratory features between patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA).Methods One hundred and forty-one patients with AS and 73 cases with nr-axSpA were recruited.Clinical and laboratory indexes of individuals were recorded in detail,Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Score (ASDAS) crp were calculated.Spondyloarthritis research consortium of Canada (SPARCC) score standard was used to evaluate the degree of bone marrow edema in sacr-oiliac joint under magnetic resonance imaging scanning.T test,rank test and x2 test were used for statistical analysis.Results The average age of patients with AS was obviously higher than that of patients with nr-axSpA (t=4.962,P＜0.01).Patients with AS were more often male,and those with nr-axSpA were more often female (82.0％ of the AS patients were men and 49.3％ of the nr-axSpA patients were men (x2=24.079,P＜0.01).Disease duration of AS was significantly longer than that of the nr-axSpA (Z=6.396,P＜0.01).The incidence of human leukocyte antigen (HLA)-B27 positive in AS was 89.4％,which was similar to that in patients with nr-axSpA (84.9％) (x2=0.884,P＞0.05).21.6％ (21 cases) of patients with AS had peripheral swollen joints,which was higher than that in nr-axSpA (2.2％,x2=8.861,P=0.003).Forty cases in AS had tender joints (41.2％),only 6 patients in nr-axSpA had tender joints (13.3％,x2=11.458,P＜0.01).Serum erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) levels in patients with AS were clearly higher than those in nr-axSpA (P＜0.01) patients.In AS,the patient global assessment (PGA),BASDAI and ASDAScrp value was significantly higher than that in nr-axSpA (P＜0.01).There were no differences in SPARCC score or incidence of bone marrow edema in sacroiliac joint in magnetic resonance imaging scanning between AS and nr-axSpA (P＞0.05).Percentage of patients with occipit-to-wall distance higher than 0 cm in AS was higher than that in nr-axSpA,and the mean distance of fingers to ground in AS was also higher than that in nr-axSpA (x2=19.844,P＜0.01;Z=5.724,P＜0.01).Chest expansion degree and Schboer's test in AS was much lower than that in nr-axSpA,respectively (Z=3.083,P=0.002;Z=5.103,P＜0.01).BASFI in AS was higher than that in nr-axSpA (Z=5.840,P＜0.01).The ratio of joint function in AS was obviously worse than that in nr-axSpA (x2=1 1.369,P=0.01).Conclusion Compared to patients with nr-axSpA,AS patients are male predominant,and have severer inflammation in clinical and laboratory findings and are worse in functional status.

Aim To study the effect of EA on the injury induced by hypoxia/reoxygenation in primary cultures of rat hippocampal neurons.Methods Rat hippocampal neurons in primary culture were used,and a apoptosis model was induced by hypoxia/reoxygenation.MTT assay and LDH releasing rate were used to detect the cell viability.The apoptosis rate of hippocampal neurons was analyzed by Hoechst 33258 staining,flow cytometry with AnnexinV-FITC and PI staining.Western blot was used to detect the protein expression of AKT and p-AKT.Results Compared to control group,three hours of hypoxia followed by sixteen hours of reoxygenation induced hippocampal neuronal apoptosis.EA could raise the neuronal viability and reduce apoptosis rate and the damage degree of rat hippocampal neurons.EA could increase the expressing of p-AKT.Conclusions EA has protective effects on damaged neurons,and the mechanism may be related to activating the PI3K-AKT signal transduction pathway.

Objective To understand treatment outcomes of patients diagnosed with type 2 diabetes aged over 30 years in Jiangninglu Neighborhood of downtown Shanghai. Methods Total 642 patients diagnosed as type 2 diabetes aged over 30 were investigated by cluster sampling in Jiangninglu Neighborhood of downtown Shanghai. Status of optimal control of diabetes in them was analyzed based on the recommendations proposed by International Diabetes Federation (IDF) for Western Pacific Region. Results and serum level of glycosylated hemoglobin Alc (HbAlc) of less than 6.5% was achieved in 37.5% (241/were achieved in 23.8% (153/642) and 18.1% (116/642) of them, respectively, and beth systolic and mmol/L was achieved in 21.7% (139/642) of all the participants investigated, triglyceride of less than 1.5 mmol/L in 46.6% (299/642), low-deusity lipoprotein-cholesterol (LDL-C) of less than 2.5 mmol/L in 23.7% (152/642) and high-density lipoprotein-cholesterol of greater than 1.1 mmol/L in 62.1% (399/of their blood glucose, blood pressure and serum LDL-C (defined as HbAlc less than 6.5%, blood pressure less than 130/80 mm Hg and LDL-C less than 2.5 retool/L). Conclusions Only 2.6% of all the patients diagnosed with diabetes aged over 30 in downtown Shanghai get optimal control of their blood glucose, blood pressure and serum lipid, so comprehensive prevention and control for diabetes shall be strengthened for them at community-level of urban areas.

AIM:TodetecthemoglobinA1c(HbA1c)andparametersofbloodglucosefluctuationinChinesenewlydiag-nosed type 2 diabetes mellitus (T2DM) patients, and further to specify the factors that were related to mean blood glucose (MBG) in this population.METHODS:Newly diagnosed T2DM patients (n=90) from 4 hospitals in Guangdong province were enrolled, and subjected to 3 d continuous glucose monitoring (CGM) after testing for HbA1c and other laboratory tests.Blood glucose data collected during CGM were used to calculate MBG and parameters of blood glucose fluctuation.RESULTS: Correlation analysis revealed that MBG was significantly related to all parameters of blood glucose fluctuation, HbA1c, fast plasma glucose ( FPG) and 2 h postprandial glucose (P<0.01), but not to sex, age or blood lipid profile.Further analysis utilizing step-wise general linear model showed that HbA1c, absolute means of daily difference ( MODD) , difference between maximal and minimal glucose ( DMMG) and FPG had the strongest relation to MBG.CONCLUSION: Factors affecting MBG of the newly diagnosed T2DMpatients in our country include HbA1c, FPG, DMMG and MODD, and thus it may be prone to misleading results that only HbA1c is applied to estimate MBG in this population.

BACKGROUNDElevation of intraocular pressure is usually associated with primary open angle glaucoma and caused by increased outflow resistance. A two-color fluorescent tracer technique was developed to investigate the hydrodynamics of aqueous humor outflow with changing intraocular pressure within the same eye, to better understand the relationship between outflow facility and effective filtration area.

METHODSEighteen enucleated bovine eyes were first perfused at 30 mmHg with Dulbecco's phosphate-buffered saline containing 5.5 mmol/L D-glucose. After a stable baseline facility, red fluorescent microspheres (0.5 microm, 0.002% v/v) were exchanged and perfused. Eyes in the one-color control group (n = 6) were immediately perfused with fixative. In the experimental group (n = 6), eyes were perfused with green tracer after intraocular pressure reduced to 7 mmHg, while in the two-color control group (n = 6), eyes were perfused with green tracer with intraocular pressure remaining at 30 mmHg. All 12 eyes were then perfusion-fixed. Outflow facility was continuously recorded in all eyes. Confocal images were taken along the inner wall of the aqueous plexus and the percent of the effective filtration length (PEFL; length of inner wall exhibiting tracer labeling/total length of inner wall) was measured. The relationships between outflow facility and PEFL were analyzed statistically.

RESULTSNo significant differences were found in baseline facilities (microl x min(-1) x mmHg(-1)) among the three groups (the experimental group: 0.93 +/- 0.12; the two-color control group: 0.90 +/- 0.19; the one-color control group: 0.98 +/- 0.13). In the experimental group, the outflow facility was significantly higher at 7 mmHg (4.29 +/- 1.01) than that at 30 mmHg (1.90 +/- 0.67, P < 0.001), which corresponded to a significant increase in the PEFL at 7 mmHg (54.70 +/- 8.42) from that at 30 mmHg ((11.76 +/- 4.56)%, P < 0.001). The PEFL labeled by red fluorescent microspheres in the experimental group ((11.76 +/- 4.56)%) showed no significant difference from that of the one-color control group ((13.39 +/- 2.19)%, P = 0.473) or the two-color control group ((11.49 +/- 4.95)%, P = 0.930). The PEFL labeled by green fluorescent microspheres in the experimental group ((54.70 +/- 8.42)%) was significantly higher than that of the two color control group ((37.34 +/- 8.17)%, P = 0.010). A positive correlation was found between outflow facility and PEFL (r = 0.897, R(2) = 0.804) in the experimental group.

CONCLUSIONSChanges in aqueous humor outflow patterns before and after a change in intraocular pressure can be successfully distinguished within the same eye using our newly developed two-color tracer perfusion technique. The PEFL showed positive correlation with the outflow facility.
