Objective To evaluate value of narrow band imaging(NBI) endoscopy for children with abdominal Henoch?Schonlein purpura ( HSP ) . Methods A total of 46 patients with abdominal HSP were enrolled into the observation group(NBI intervention) from November 2010 to February 2016.Diagnostic rates of white light and NBI endoscopy in abdominal HSP patients, IgA positive rates of targeted biopsies and severe complications were retrospectively analyzed. A total of 25 abdominal HSP patients with no NBI intervention admitted from 2007 to 2009 were randomly enrolled into control group. Data of the control group were compared with those of observation group. Results In observation group, the diagnostic rate under NBI was significantly higher than that under white?light endoscopy[91. 3%(42/46)VS 67. 4%(31/46),χ2=8. 02,P<0. 05]. IgA positive rates of targeted biopsies under NBI was significantly higher than that under white?light endoscopy [ 95. 7%( 88/92 ) VS 69. 6%( 64/92 ) ,χ2 = 21. 79, P<0. 05 ] . Three patients developed such serious complications as digestive hemorrhage as predicted. Compared with control group, abdominal pain and blood stool relief time (10. 96±5. 32 d VS 19. 68±4. 29 d,t=7. 50,P<0. 01), fasting time(10. 37±5. 42 d VS 8. 80± 3. 71 d,t=7. 73,P<0. 01), hospital stay (18. 80±7. 11 d VS 23. 12±4. 36 d, t=3. 16,P<0. 01), time of stool occult blood negative ( 11. 41 ± 6. 30 d VS 19. 12 ± 4. 09 d, t=6. 22, P<0. 01 ) in observation group were significantly shortened. Conclusion NBI endoscopy is valuable for improving the diagnostic accuracy and biopsy accuracy and complication prediction of abdominal Henoch?Schonlein purpura in children.

Objective To evaluate the value of endoscopy with narrow-band imaging(NBI)for tar-geting biopsy of lesions in children with allergic colitis. Methods The colorectal lesions under the model of traditional white light imaging and NBI in children with allergic colitis were observed and recorded. The re-sults of biopsy under white light imaging and NBI were compared with postoperative pathological diagnosis. Results A total of 60 patients completed the study. Under NBI,47(78. 3%)rectal lesions,52(86. 7%) sigmoid colon lesions and 19(31. 7%)descending colon lesions were found. There were 21(35. 0%),25 (41. 7%),and 8(13. 3%)lesions in the transverse colon,ascending colon and iloececus,respectively. For the lesions in transverse colon and ascending colon,the detection rate under NBI was significantly higher than that under white light endoscopy[35. 0% VS 16. 7%(10/ 60),P<0. 05;41. 7% VS 18. 3%(11/ 60),P<0. 05]. No significant difference was found between two methods for the sigmoid and rectal lesion[86. 7% VS 83. 3%(50/ 60),P>0. 05;78. 3% VS 76. 7%(46/ 60),P>0. 05].There was no significant difference in ileo-cecus and descending colon[13. 3% VS 5. 0%(3/ 60),P>0. 05;31. 7% VS 28. 3%(17/ 60),P>0. 05]. The targeted biopsy results by NBI indicated that the ratio of EOS≥6/ HP was significantly higher than the biopsy results by white light imaging. Conclusion NBI is easy to operate and can discern the microcosmic structure which cannot be observed by the traditional endoscopy. It can provide higher diagnostic accuracy of allergic colitis. After suspicious lesions were found under conventional endoscopic check,NBI could be used to guide the targeted biopsy.

Objective To investigate the effect of coenzyme complex on the cardiac and renal functions of patients with type 2 cardiorenal syndrome. Methods Sixty-two patients with type 2 cardiorenal syndrome were enrolled in from June 2013 to December 2014 in Zhujiang Hospital , Southern Medical University. These patients divided were into routine group (n = 31) and coenzyme complex (n = 31). The therapy scheme of coenzyme complex group was on the basis of routine group with coenzyme complex intravenous drip , 400 U/day for 2 weeks. The cardiac function was determined by New York Heart Function Assessment, and the cardiac ultrasound, the levels of BNP. The renal function was determined by serum creatinine and urine volume. Results Compared with routine group, the rates of NYHA Ⅲ and Ⅳ were reduced, the LVEF levels were increased and the levels of BNP were increased (P < 0.05). The serum creatinine was decreased and urine volume were increased in the coenzyme complex group (P<0.05). Conclusion Coenzyme complex could improve the cardiac and renal functions of the patients with type 2 cardiorenal syndrome.

Objective To explore the value of left atrium volume index (LAVI) in the diagnosis of heart failure with preserved ejection fraction (HFPEF). Methods Seventy-seven patients with HFPEF and 33 patients without HFPEF who had been treated from May 2012 to September 2013 in Guangdong General Hospital were en-rolled. The clinical data and a series of ultrasound parameters were collected and analysed. The relationship between LAVI, LAV, and other indexes of diastolic function was determined by Pearson correlation analysis. The value of LAVI and LAV for diagnosing HFPEF was compared by the ROC curve. Results LAVI and LAV of were signifi-cantly greater in HFPEF group than in non-HFPEF group. LAV and LAVI were significantly associated wtih HEPEF. The area under the ROC curve (AUC) of LAVI increased significantly as compared with the AUC of LAV (0.832 vs. 0.799, P<0.05). With a cut-off value of 30 mL/m2, the specificity and sensitivity for diagnosing HEPEF were 64.9%and 84.8%, respectively. Conclusions LAVI may be valuable in the diagnosis of HFPEF.

Objective: To explore the changes of peripheral leukocyte’s telomere length (LTL) in patients of premature coronary artery disease (PCAD) with inlfuencing factors. Methods: Our research was conducted in 2 sets of groups, by coronary artery condition: PCAD group,n=128 including 88 patients with ACS, 40 with SCAD and Non-CAD group,n=128 subjects; by age status: the age≤30 years, 31-40 years, 41-50 years, 51-60 years had 2, 14, 65, 47 patients in each group respectively. Peripheral LTL was detected by lfuorescent quantitative analysis, the relationship between LTL and PCAD with inlfuencing factors were studied by Spearman correlation analysis. Results: In PCAD group, compared with SCAD patients, ACS patients had more male gender, higher Gensini score, lower T/S ratio and shorter LTL, allP<0.05. Compared with Non-CAD group, PCAD group had decreased T/S ratio (0.88 ± 0.86) vs (1.10 ± 0.57),P<0.05. T/S ratio was negatively related to age in both PCAD group (r=-0.275,P=0.002) and Non-CAD group (r=-0.316,P=0.000). Spearman correlation study presented that in PCAD group, LTL was negatively related to hyperlipidemia (r=-0.415,P=0.049) and diabetes (r=-0.472,P=0.036); multi linear regression analysis indicated that in PCAD group, LTL was negatively related to age (B=-0.023,P=0.038) and in Non-CAD group, LTL was negatively related to age (B=-0.027,P=0.000), smoking (B=-0.278,P=0.012), HDL-C (B=-0.297,P=0.046). Conclusion: PCAD had more male ACS patients with shorter LTL and severer coronary lesions; LTL was negatively related to hyperlipidemia and diabetes, age was an important inlfuencing factor for LTL shortening.

Hemophagocytic lymphohistiocytosis (HLH) in different ethnicities has been described in the literature, but few cases in patients of Chinese descent have been reported. Here, we describe the case of a Chinese neonate presenting with HLH carrying novel, compound heterozygous mutations of the UNC13D gene, including [c.2295_2298delGCAG, p.Glu765Aspfs*27] in exon 23, c.-250C>T, c.1+30G>A, c.279C>T, c.888G>C, c.18+36A>G, c.20-48T>C, c.1977C>T, c.2296C>T, c.24-46C>T, c.26-9_26-8insC, c.2599A>G, c.28+48C>T and c.3198A>G, some of which have not been reported in the literature. Cytokine profile analyses were performed in this patient, and the results were consistent with our previous findings in HLH patients. Cytokine profile monitoring may be helpful in differentiating among various clinical phases of HLH.

Glycoprotein D (gD) of Herpes simplex virus type 2 (HSV-2) is a key factor mediating the entry of HSV-2 into host cells. In order to explain the mechanism underlying the gD-mediated receptor-binding and viral entry, we performed a structural study on HSV-2 gD. The ectodomain of the gD protein encompassing residues 1 to 285 was expressed by baculovirus-infected insect cells as a secreted soluble protein with a C-terminal hexa-his tag. The protein was then purified by affinity and size-exclusion chromatography. The purified protein was successfully crystallized using the hanging-drop vapor-diffusion at 18 degrees C in a condition consisting of 0.1 mol/L Hepes pH 7.2, 5% (V/V) 2-methyl-2,4-pentanediol (MPD) and 10% PEG 10 000. The crystals diffracted to 1.8 angstroms resolution and belonged to space group P21, with unit-cell parameters alpha = 63.6, b = 55.4, c = 65.3 angstroms, beta = 96.3 degrees.
