Objective To explore the curative effect of endourological treatment of pediatric urethral hemangioma with holmium laser.Methods Two children with urethral hemangioma were enrolled in this study. One urethral hemangioma in the bulbous urethra,another in the posterior urethra. Modalities of diagnosis before operation included B ultrasound,intravenous urogram(IVU) and endoscopy. Two children with urethral hemangioma underwent holmium laser therapy.Results After endourological trearment with holmium laser, two children had been cured.Six months to 4 years follow-up did not find recurrent urethral hemangioma.Conclusions The diagnosis of pediatric urethral hemangioma mainly rely on endoscopy. Endourological treatment with holmium laser is a minimally invasive,safe and effective methods for pediatric urethral hemangiomas.

Through morphological observation, HE staining, TRAP staining and toluidine blue staining of bone resorption pits to identify osteoclasts which obtained by 1α, 25-(OH)2 VitD3 inducing rabbit bone marrow cells. Three indicators-TRAP staining, TRAP enzyme activity detecting and the number and area of bone resorption pits were adapted to detect the effect of Sargentodoxae caulis on the activity of osteoclasts. Culturing MC3T3-E1 Subclong 14 cells and detecting the effect of S. caulis on differentiation and proliferation of them by MTT and detecting the alkaline phosphatase in cells. The results show that all of the low, middle and high doses of water and alcohol extracts of S. caulis have significant inhibition on osteoclast differentiation and bone resorption ability in a dose-dependent manner. The low and middle doses of water and alcohol extracts of S. caulis can stimulate differentiation and proliferation of MC3T3-ElSubclone 14 cells, which indicates S. caulis can prevent osteoporosis and the function could be achieved by inhibiting osteoclast activity and promoting the proliferation and differentiation of osteoblasts.

Objective To assess the short-term effect of cardiac resynchronization therapy (CRT) by speckle tracking strain imaging(STI). Methods Sixteen chronic heart failure patients(CHF) with CRT were enrolled. The time to peak systolic longitudinal strain and the time to peak systolic radial strain were derived from the LV apical views, and the time to peak systolic circumferential strain was derived from the parasternal short axis. The standard deviation for time to peak longitudinal, radial and circumferential strain in the 18 segments (LS-SD18, RS-SD18, CS-SD18) and the maximal temporal difference of any two segments(LS-dif, RS-dif, CS-dif) were calculated as a strain-derived dyssynchrony index. The difference of LS-SDIS, RS-SD18, CS-SD18 between 1 month,3 months after CRT and baseline (△LS-SD18, △RS-SD18, △CS-SD18) was calculated. The correlation between △LS-SD18,ARS-SD18,△CS-SD18 and the reduction of end-systolic volume at follow-up(△ESV%) were analyzed. Results The LS-SD18, RS-SD18,CS-SD18 and RS-dif were decreased significantly 1 month,3 months after CRT.△RS-SD18 was correlated with △ESV% 3 months after CRT(r = 0. 694). Conclusions The strain-derived dyssynchrony index is great significient for short-term effect of CRT.

Objective To evaluate the tissue motion tracking of mitral annular displaeement(TMAD) method in the assessment of short-term effect of cardiac resynchronization therapy (CRT). Methods Twenty six chronic heart failure (CHF) patients with CRT were detected by TMAD. The maximal displacement of the six points of mitral annulus(DS), the standard deviation of the time to regional peak systolie displacement of the six points (Td-sd) and the maximal temporal difference of any two points(Tds-diff) were compared before and one month after CRT. And the correlation between mean displacement and left ventricular ejection fraetion(LVEF),left ventricular end systolic volume(LVESV), fraction area change (FAC) was analyzed. Results Compared with the pre-operatively, the displacement and the mean displaeement of the six points of mitral annulus were significantly increased(P<0.01),Tds diff and Td-sd were decreased(P<0.05) one month after CRT. TMAD correlated with LVEF,LVESV and FAC (r =0.419, r = 0.529, r = 0.567, P <0.05) one month after CRT. Conclusions TMAD is a new technology to evaluate the short-term effect of CRT.

[ ABSTRACT] AIM: To observe the effect of circadian rhythms on wound healing of mouse corneal epithelium. METHODS:The C57BL/6 male mice were used in the study.A part of corneal epithelium (2 mm in diameter) was struck off by a golf-like knife to form a round wound area.The dynamics of epithelial healing in the wound area were ob-served under microscope with fluorescein staining.In addition, with related antibodies and DAPI, the dynamic changes of the neutrophils, platelets and dividing cells were also investigated.RESULTS:The healing rates in LL group (12 h light/12 h light) and DD group (12 h dark/12 h dark) were obviously slower than that in LD group (12 h light/12 h dark), mainly showing delayed re-epithelialization, decreased epithelial cells, increased diameter of blood vessel, and delayed re-cruitment of neutrophils and platelets, but more cell number.CONCLUSION:Disruption of circadian rhythms significant-ly inhibits the wound healing of corneal epithelium, mainly through delaying the inflammation and re-epithelialization, but aggravating the inflammatory responses.

OBJECTIVE:To observe the effect of Maren pills combined with lactulose preventing opioid-induced constipation (OIC) in patients with cancer pain. METHODS:281 cases of advanced cancer pain were selected and divided into Maren pills group,lactulose group and drug combination group. 3 groups were given opioid to relieve pain,and additionally received Maren pills,lactulose or drug combination(lactulose for 3 d and then Maren pills for 3 d instead,repeated in the same way)to treatment OIC prophylactically. The constipation conditions of 3 groups were observed and recorded at 2,4 and 6 weeks after the therapy. And then the data were analyzed statistically. RESULTS:The regular doses of Maren pills and lactulose alone or combination had prevention effect on OIC. Drug combination showed better long-term prevention effect;there were statistically significant difference in constipation conditions between grug combination group and other 2 groups after 4 and 6 weeks of therapy (P<0.05 or P<0.01). CONCLUSIONS:Maren pills combined with lactulose are obvious benefit for constipation prevention and relief in cancer pain patients who use opioid for a long time.

INTRODUCTION:
Associations of variations in PLA2R1 and HLA-DQA1 genes with susceptibility to idiopathic membranous nephropathy (IMN) have been well documented. Association with spontaneous remission, however, is poorly defined in the Chinese Han population.
METHODS:
A Chinese cohort of 117 IMN patients and 138 healthy controls were recruited between July 2009 and November 2019. Case-control studies for single-nucleotide polymorphisms (SNPs) within HLA-DQA1 (rs2187668) and PLA2R1 (rs35771982, rs4664308, rs3749117, rs3749119) genes were performed. The contributions of these polymorphisms to predict susceptibility, titre of autoantibodies against the M-type phospholipase A2 receptor (anti-PLA2R1), glomerular PLA2R1 expression, and spontaneous remission were analysed.
RESULTS:
We found that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) were strongly associated with IMN susceptibility, while SNP (rs2187668) within HLA-DQA1 did not increase the risk of IMN. All SNPs in PLA2R1 and HLA-DQA1 were not statistically associated with anti-PLA2R1 titre, glomerular PLA2R1 expression and spontaneous remission after Bonferroni correction (
CONCLUSION
This study confirms that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) are risk factors for IMN. We found excellent association of serum albumin level, anti-PLA2R1 titre and glomerular PLA2R1 positivity with non-spontaneous remission in IMN.
