Congenital coronary sinus anomalies are extremely rare, and they have received relatively little attention. This is probably due to the lack of both clinical symptoms and significant cardiac functional disturbance. We present two cases of a coronary sinus anomaly and briefly review the literature. Recognizing and being familiar with the variations of a congenital coronary sinus anomaly in congenital heart disease may avoid a misinterpretation of cardiac catheterization findings and the troublesome disruption of coronary sinus blood return during the surgical management of cardiac lesions.

Background: Ultrasound-guided minimally invasive procedures are widely used to treat thyroid diseases. The objective of this study was to assess the efficacy and safety of ethanol ablation (EA) in comparison with other non-surgical options in the treatment of benign thyroid cystic nodules. Methods: We conducted a systematic search of studies on EA for thyroid cystic nodules, mainly in the Ovid-MEDLINE and Embase, Web of Science, and Cochrane databases. The standardized mean difference (SMD) of the volume reduction ratio (VRR) after EA versus other non-surgical treatments comprised the primary outcome, whereas the odds ratio (OR) of therapeutic success rates between the two groups comprised the secondary outcome. Results: The meta-analysis included 19 studies (four randomized controlled trials and 15 non-randomized studies) with 1,514 participants. The cumulative VRR of EA was 83.908% (95% confidence interval [CI], 79.358% to 88.457%). EA had a significantly higher pooled VRR (SMD, 0.381; 95% CI, 0.028 to 0.734; P=0.030), but not a significantly higher pooled therapeutic success rate (OR, 0.867; 95% CI, 0.132 to 5.689; P=0.880), than other forms of non-surgical management including radiofrequency ablation (RFA), polidocanol sclerotherapy, and simple aspiration with or without saline flush. However, the VRR and therapeutic success rate were not significantly different between EA and RFA. Major complications were recorded only in six patients (0.53%) with self-limiting dysphonia. Conclusion The role of EA as the first-line treatment for benign thyroid cysts and predominantly cystic nodules is supported by its high effectiveness and good safety profile compared to other currently available non-surgical options.

Objective A resistin binding peptide (RBP) was selected by phage display in our previous work. Studies had shown that RBP could antagonize the role of resistin on the lipid metabolism and endocrine function of adipose tissue, but whether RBP affects the insulin secretion of pancreatic cells is still unknown. The aim of this study is to assess the effect of RBP on basal insulin secretion in RINm5F insulinoma cells. Methods The cell viability was measured by 3-[4,5-dimethyhhiazol-2-yl]-2,5-diphenyltetra-zolium bromide (MTT) cytotoxicity assay. The supernatants were assayed for insulin content by enzyme linked immunosorbent assay (ELISA). Reverse transcriptase-PCR assay and Western blotting were used to determine the expression of glucose transporter 2 (GLUT2) involved in insulin secretion. Cytosolic Ca2+, the trigger of insulin exocytosis, was analyzed with the fluorescent probe FURA-3/AM. Results RBP did no effect on the cell viability with a concentration of 10-8-10-12mol/L of 2 hours intervention. But it stimulated basal insulin secretion of RINm5F cells, accompanied by up-regulated increased expression of GLUT2 and elevated concentration of cytosolic Ca2+. Conclusion RBP could stimulate basal insulin secretion without affecting the cell viability.

OBJECTIVETo compare therapeutic effects of acupuncture combined with TDP radiation and western medicine on restless legs syndrome.

METHODSOne hundred and fifty-eight cases of restless legs syndrome were randomly divided into an observation group and a control group, 79 cases in each group. The treatment group were treated with acupuncture at Shenshu (BL 23), Dachangshu (BL 25), Guanyuanshu (BL 26), Zhibian (BL 54), Taixi (KI 3), etc., and TDP radiation. The control group were treated with L-Dopa. Clinical observation was made for 30 days.

RESULTSIn the observation group, 42 cases were cured, 30 cases were effective and 7 cases were ineffective with a total effective rate of 91.1%; in the control group no case was cured, 24 cases were effective and 55 cases were ineffective with a total effective rate of 30.4%, with a significant difference between the two groups in the total effective rate.

CONCLUSIONAcupuncture combined with TDP radiation has a better therapeutic effect on restless legs syndrome.

Clinical evidence of hematopoietic restoration with umbilical cord blood (UCB) grafts indicates the UCB can be a useful source of hematopoietic stem cells for routine bone marrow reconstitution. Considering (10 +/- 5) x 10(8) nucleared cells per cord blood unit, there is a potential limitation for the use of cord blood in adults, which, however, can be overcome by ex vivo expansion of cells. A prerequisite for expansion is the significantly higher recovery of MNC, CD34+ cells and colony-forming cells (CFC) by thawing cryopreserved MNC. Cooling rate always acts as a critical factor that can affect the recovery of cells. Although the rate of - 1 degrees C/min is adopted in most of the cryopreservations, no data has been reported about the detailed effects of different cooling rates. The aim of the study was to reveal the different effects of cooling rates on cryopreservation of hematopoietic stem cells from cord blood. UCB samples were collected, and cryopreserved as mononuclear cells (MNC) with different cooling rates of - 0.5 degrees C/min, - 1 degrees C/min, - 5 degrees C/min, and the recovery and viability of MNC and CD34+ cells, the clonogenic capacity and the ex vivo expansion potential of UCB progenitor cells were evaluated after thawing. With - 1 degrees C/min cooling rate, the recovery of MNC reached 93.3% +/- 1.8% , viability 95.0% +/- 3.9% , recovery of CD34+ cells 80.0% +/- 17.9% , and clonogenic recovery were 87.1% +/- 5.5%, 88.5% +/- 8.9%, 86.2% +/- 7.4% for BFU-E CFU-GM CFU-MK, respectively. After 14 days of liquid culture, no significant difference was detected in CFC expansion between fresh and cryopreserved MNC cells with - 1 degrees C/min cooling rate, but this was not the case with - 0.5 degreesC/min and - 5 degrees C/min. In conclusion, it was demonstrated that controlling the rate at - 1 degrees C/min is more suitable for cryopreservation of hematopoietic stem cells than - 0.5 degrees C/min and - 5 degrees C/min.

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease and is one of the main causes of death and disability in neonates. The etiology and pathogenesis of neonatal ARDS are complicated. It is an acute pulmonary inflammatory disease caused by the lack of pulmonary surfactant (PS) related to various pathological factors. It is difficult to distinguish neonatal ARDS from other diseases. At present, there is no specific treatment method for this disease. Respiratory support, PS replacement, extracorporeal membrane oxygenation, nutrition support and liquid management are main treatment strategies. This paper reviews the research advance in etiology, clinical characteristics, diagnosis and treatment strategies of neonatal ARDS.
