Objective To investigate the levels of serum surfactant protein D (SP-D) and mannosebinding lectin (MBL) in infants with cytomegalovirus (CMV) pneumonia with the severity of disease.Methods A total of 101 hospitalized infants with CMV pneumonia were enrolled from January 2011 to December 2012.These patients were divided as the severe pneumonia group (n =48) and the mild pneumonia group (n =53) according to physical sign of lung and complication.Another 55 infants who were hospitalized in the same period with non-infectious diseases were used as the control group.Serum levels of SP-D and MBL were detected by enzyme-linked immunosorbent assay.Blood gas analyzer was used to measure arterial partial pressure of oxygen (PaO2) of the blood in severe patients.Results The mean serum SP-D levels in the severe pneumonia group [(150.08 ±52.59)ng/ml] and the mild pneumonia group [(109.67 ±31.39)ng/ml] were significantly higher than those in control group [(41.33 ± 16.42) ng/ml] (P ＜ 0.01), and higher in the severe pneumonia group than in the mild pneumonia group (P ＜ 0.01).However, there was no significant difference in serum MBL between all groups (P ＞ 0.05).In severe patients, serum SP-D levels were negatively correlated with PaO2 (r =-0.565, P ＜ 0.01).Conclusion Serum SP-D is associated with the severity of CMV pneumonia, but MBL shows no relation.The serum SP-D levels has an important clinical significance in judgment the sererity of infants with CMV pneumonia.

Objective To observe the effects of glucagon like peptide-1 (GLP-1) analogues liraglutide on expressions of nitric oxide synthase (NOS) and cyclo-oxygen-ase (COX)2 in renal medulla of type 2 diabetes rats, and the mechanism of its lowering blood pressure and promoting excretion of water and salt in kidney. Methods Type 2 diabetes model rats were generated by high-fat and high-sugar feeding for 8 weeks followed by intraperitoneal injection of streptozotocin (STZ). Subse?quently, eighteen type 2 diabetes rats were divided into two groups: liraglutide treatment group (DMT) and diabetes group (DM). Twelve normal rats were divided into two groups: liraglutide treatment wild type group (WTT) and wild type group (WT). DMT and WTT groups were given liraglutide (200μg/kg) by subcutaneous injection, DM and WT groups were given equivalent normal saline by the same way. The levels of blood glucose and blood pressure were detected at 0, 2, 4 and 6 weeks after treatment in groups of rats. Samples of urine were collected for detecting ion concentrations (K+, Na+and Cl-) af?ter treatment for six weeks. Rats were sacrificed and blood samples were collected for detecting ion concentrations (K+, Na+and Cl-). The expression levels of NOS and COX2 mRNA and protein in renal medulla were detected by real-time PCR and Western blot assay. Results After treating with liraglutide, the values of blood glucose (F=5.933, P<0.05) and blood pres?
sure (F=22.070, P<0.05) were gradually decreased in DMT group. After treatment with liraglutide for 6 weeks, the values of blood glucose (mmol/L:12.78 ± 3.82 vs. 18.75 ± 1.68) and blood pressure (mmHg:119.98 ± 4.43 vs. 136.42 ± 4.48) were signifi?cantly decreased (P<0.05) in DMT group than those of DM group (P<0.05). There were no significant differences in the concentrations of K+, Na+and Cl-between the two groups. There were higher levels of K+(mmol/L:46.55 ± 6.43 vs. 33.13 ± 9.71), Na+(mmol/L:56.33±8.83 vs. 41.20±7.25) and Cl-(mmol/L:159.81±25.06 vs. 71.44±12.99) in urine in DMT group than those of DM group (P<0.05). The mRNA levels and protein expressions of NOS and COX2 in renal medulla were significant?ly increased in DMT group than those of DM group (P<0.05). Conclusion GLP-1 analogues liraglutide may enhance the expression of COX2 by increasing the expression of NOS to excrete water and salt, and decrease blood pressure.

OBJECTIVETo analyze genomic copy number variations (CNVs) in two sisters with primary amenorrhea and hyperandrogenism.

METHODSG-banding was performed for karyotype analysis. The whole genome of the two sisters were scanned and analyzed by array-based comparative genomic hybridization (array-CGH). The results were confirmed with real-time quantitative PCR (RT-qPCR).

RESULTSNo abnormality was found by conventional G-banded chromosome analysis. Array-CGH has identified 11 identical CNVs from the sisters which, however, overlapped with CNVs reported by the Database of Genomic Variants (http://projects.tcag.ca/variation/). Therefore, they are likely to be benign. In addition, a -8.44 Mb 9p11.1-p13.1 duplication (38,561,587-47,002,387 bp, hg18) and a -80.9 kb 4q13.2 deletion (70,183,990-70,264,889 bp, hg18) were also detected in the elder and younger sister, respectively. The relationship between such CNVs and primary amenorrhea and hyperandrogenism was however uncertain. RT-qPCR results were in accordance with array-CGH.

CONCLUSIONTwo CNVs were detected in two sisters by array-CGH, for which further studies are needed to clarify their correlation with primary amenorrhea and hyperandrogenism.
