Objective To study the expression of interleukin-6 (IL-6) and hepcidin in patients with diffuse large B-cell lymphoma (DLBCL) and their significance in anemia. Methods 45 DLBCL patients with or without anemia were analyzed. Peripheral blood samples were collected during diagnosis, and the concentrations of IL-6, hepcidin, serum ferritin and hemoglobin (Hb) were measured. 24 healthy volunteers were collected as controls. Results The levels of plasma hepcidin and IL-6 in patients with DLBCL were (347±171)μg/L and 0.27 ng/L (0-9.61 ng/L), respectively, and compared with those [(175 ± 92)μg/L] and 0 ng/L in healthy controls, the differences were statistically significant (both P<0.001). Plasma hepcidin levels in patients with high lactate dehydrogenase (LDH) (P=0.003), B symptoms (P=0.040) or age-adjusted international prognostic index (IPI)>1 (P=0.010) were increased. The levels of IL-6 in patients of male (P=0.003), stage Ⅲ-Ⅳ (P=0.008) or IPI>1 (P=0.004) were significantly higher. The level of hepcidin was highly correlated with serum ferritin (r=0.77, P<0.001), weakly correlated with IL-6 (r=0.31, P=0.030), and not correlated with Hb (r=-0.12, P=0.3). There was a negative correlation between IL-6 expression and Hb (r=-0.35, P=0.009). Multivariate analysis showed that IL-6 could predict anemia (P=0.03), whereas hepcidin could not (P=0.89). Conclusion The elevated hepcidin level is frequent in DLBCL, and the elevated IL-6 plays the major role in the development of anemia.

OBJECTIVE:
To explore a simple and accurate method for localization of upper airway obstruction in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and provide instructions for surgical treatment.
METHOD:
Fifty OSAHS patients confirmed by PSG underwent acoustic rhinometric and pharyngometric assessment by Eccovision. The parameters were recorded, including nasal minimal cross-sectional area (NMCA), distance of MCA from the nostril (DCAN), minimum cross-sectional area at the nasal valve(MCA), nasal resistance (NR) and nasal volume from 0 to 6 cm from the nostril (NCV), as well as pharyngeal cross-sectional area (CSA) and volume from 4.8 to 15.0 cm. The sensitivity and specificity of acoustic rhinometry and pharyngometry on localization of airway obstruction was determined by a comprehensive imaging and endoscopic study.
RESULT:
In 50 cases with severe OSAHS, NMCA, DCAN, MCA, NCV, NR were (0.61 +/- 0.35) cm2, (2.06 +/- 0.12) cm, (0.87 +/- 0.12) cm2, (9.24 +/- 2.31)cm3 and (0.51 +/- 0.32)kPa/(L x min), respectively. Pharyngeal CSA and volume were statistically significantly lower than that in control group (P < 0.01). The value of DCAN was (2.06 +/- 0.12) cm, (9.50 +/- 4.08) cm, (13.10 +/- 2.52) cm in type I II, III patient, respectively. Compared with the control group, the difference was statistically significant.
CONCLUSION
Acoustic rhinometry and pharyngometry is a simple and safe method in localization of airway obstruction in patients with OSAHS.

Objective:To investigate the relationship between neutrophil/lymphocyte ratio (NLR) and bone mineral density (BMD) in rheumatoid arthritis (RA), and to evaluate its diagnostic value in RA with osteoporosis.Methods:134 RA patients and 69 healthy subjects were screened and NLR levels were compared between the two groups. Bone mineral density of lumbar L1-4 and femoral neck was measured by dual energy X-ray absorption (DXA), and the patients were divided into normal bone mass group (44 cases), reduced bone mass group (47 cases) and osteoporosis group (43 cases). Height, weight, course of disease, mean platelet volume, erythrocyte sedimentation rate (ESR), C-reactionprotein (CRP), complement C3, complement C4, rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibody, bone mineral density and other related indicators were recorded. The differences of NLR, body mass index(BMI) gender, age and other indicators among the three groups were compared by One-way Analysis of Variance (ANOVA) and Kruskal-Wallis test, or χ2 test. Correlation analysis was conducted to detect the correlation between NLR, bone mass and each indicator, and ordered multi-classification Logistic regression analysis was used to evaluate the im-pact of each indicator on osteoporosis, and receiver operating characteristic curve (ROC) was used to predict the diagnostic value of NLR and combined related indicators on osteoporosis. Results:NLR of RA patients (3.1±1.7) was higher than that of healthy controls (1.7±0.5) ( F=21.27, P<0.001). In the osteoporosis group, the reduced bone mass group, and the normal bone mass group, age (66±8), (62±10), (50±13), disease course (15±10), (9±8, (7±7), BMI (20±4) kg/m 2, (22±3) kg/m 2, (24±3) kg/m 2, NLR (3.9±2.3, 2.7±1.2, 2.6±1.0), CRP (41±43) mg/L, (28±34) mg/L, (18±26) mg/L, ESR (46±30) mm/1 h, (36±26) mm/1 h, (26±20) mm/1 h were significantly different among the three groups ( χ2=32.92, P<0.001; H=17.41, P<0.001; F=12.04, P<0.001; H=11.62, P=0.030; H=13.78, P=0.001; F=7.18, P=0.001). Correlation analysis showed that NLR was correlated with CRP, ESR, anti-CCP antibody, femoral neck bone mineral density, DAS28 score and age. The correlation coefficients were 0.49 ( P<0.001), 0.39 ( P<0.001), 0.30( P<0.001), -0.18( P=0.042), 0.50( P<0.001), 0.17( P=0.046), respectively. Femoral neck was correlated with age, BMI, course of disease, CRP, ESR. The correlation coefficients were -0.46( P<0.001), 0.38 ( P<0.001),-0.39 ( P<0.001), -0.34 ( P<0.001), the correlation coefficients of L1-4 with age, BMI, CRP and ESR were -3.41( P<0.001), 0.39( P<0.001), -0.22( P=0.010), -2.42( P=0.005), respectively. There was no correlation between bone mineral density and DAS28 and anti-CCP antibody. Ordered multi-classification Logistic regression analysis showed that: age, course of disease, NLR and ESR were risk factors for osteoporosis, and their OR values were 1.12 ( P<0.001), 1.05 ( P=0.025), 1.29 ( P=0.031), 1.02 ( P=0.039), 0.28 ( P=0.008), respectively. Body mass index ( OR=0.76, P<0.001) were protective factors. ROC curve showed that the AUC area of NLR was 0.68, the AUC area of NLR, BMI, age, sex and course of disease was 0.90, the cut-off value was 0.20, sensitivity was 0.95, and specificity was 0.73[95% CI(0.84, 0.95)]. Conclusion:In osteoporosis, NLR is related to bone mass and disease activity of patients with rheumatoid arthritis. Combined with other related indexes, NLR can be used as a predictive diagnostic index and has a guiding role in clinical practice.

OBJECTIVETo assess the association of G protein-coupled estrogen receptor(GPER) gene polymorphism with social function of children with attention deficit hyperactivity disorder (ADHD).
METHODSThe social function of 135 children with ADHD were assessed by Weiss Functional Impairment Scale-Parent form (WFIRS-P). The coding region of GPER gene of all patients was subjected to Sanger sequencing. The association of polymorphisms with the social function of the ADHD children was analyzed.
RESULTSIn the case group, the social function scores of Learning and School and Risky Activities of boys were significantly higher than those of girls (t=2.704, P=0.008; t=2.289, P=0.027). No significant difference was found in the genotypic frequencies of the c.-9T/C and c.789G/A loci between different genders. But the learning and school scores of those with a TC genotype for the c.-9T to C locus were significantly higher than those with a TT genotype (t= 2.159, P=0.033).
CONCLUSIONFor children with ADHD, the social function of Learning and School of those with a TC genotype of the GPER gene c.-9T/C locus is more severely damaged compared with those with a TT genotype.
