ABSTRACT

Objective:To explore the value of transesophageal echocardiography(TEE) guidance for transcatheter DragonFly? system edge-to-edge tricuspid regurgitation (TR) repair.Methods:Five cases who were chosen in the Second Affiliated Hospital, Zhejiang University School of Medicine from December 2020 to January 2021 with surgical high-risk and severe functional TR underwent transcatheter DragonFly edge-to-edge repair with the guidance of TEE. Preoperative TEE was used to evaluate the tricuspid valve anatomy and the origin and etiology of regurgitation in detail; intra-procedure guidance of TEE was performed during the DragonFly system for tricuspid valve edge-to-edge repair intervention and after release of the DragonFly clip, the effect of surgery was assessed immediately and compared with pre-procedure TEE.Results:A total of 10 DragonFly clips were implanted in 5 patients (3 in each of patients, 2 in 1 patient, and 1 in each of patients). One of the 3 clips in 1 patient fell off unilaterally from the septal valve after release, and the other 9 clips were well positioned and fixed. Immediately post-operation assessment by TEE depicted the TR in 3 patients declined to mild and 2 to moderate. The vena contracta area by using three-dimensional color blood flow quantitative assessment was reduced[(0.93±0.26)cm 2 vs (0.20±0.11)cm 2]. No complications such as serious tricuspid valve injury, pericardial tamponade, thromboembolism occurred in the 5 patients. Conclusions:TEE plays an important role in guiding and monitoring transcatheter DragonFly system edge-to-edge TR repair during the entire procedure.

ABSTRACT

Objective:To evaluate the efficacy and safety of dienogest (DNG) in the treatment of refractory endometriosis-associated pain (REAP).Methods:In this study, REAP was defined according to the following criteria: (1) the pain duration was ≥12 months and visual analogue scale (VAS)≥60 mm; (2) the previous treatments with over two medicines like oral contraceptives and levonorgestrel-releasing intrauterine system failed to achieve satisfactory relief of pain, with VAS reduction less than 50%; with gonadotropin-releasing hormone agonist or mifepristone, the pain could be controlled temporarily, but it recurred after discontinuation of medicines; (3) the pain could not be relieved by surgery or even repeated surgeries. In the present study, 48 patients with REAP were treated with DNG 2 mg/day orally and the clinical outcomes were retrospectively analyzed. The VAS scores, levels of CA 125, estradiol, FSH, LH and changes in the size of endometriotic lesions before and after treatment were compared respectively. The side effects were also analyzed. Results:The average duration of DNG treatment was (20.1±12.8) months. After 3 months of medication, the VAS score was significantly reduced from (77.9±15.8) mm to (20.8±10.7) mm ( P<0.01), and CA 125 level was significantly reduced from (95±139) kU/L to (38±45) kU/L ( P<0.05). The effects were maintained with continuation of DNG treatment. Endometriotic lesions tended to shrink, after 12 months of DNG treatment, the size of ovarian endometriomas was reduced significantly from (3.1±1.0) cm to (1.9±1.2) cm ( P<0.05). The mean level of estradiol was maintained at 124.82-221.04 pmol/L and levels of FSH and LH did not change significantly during the treatment. The major side effect was irregular bleeding (75%, 36/48). Conclusions:DNG could effectively relieve REAP and is a well-tolerated therapy. It may supply an alternative option for patients with REAP.

ABSTRACT

BACKGROUND:Liver fibrosis is a kind of chronic and active disease that is caused by various causes and characterized by the excessive accumulation of extracelular matrix. At present, use of Chinese herbs for the treatment of hepatic fibrosis has obvious advantages. Salvia miltiorrhiza has been shown to be highly effective in the treatment of hepatic fibrosis. However, the underlying mechanism needs further investigation. OBJECTIVE:To investigate the effects of TanshinoneⅡA on the expression levels of transforming growth factor-β/Smads signaling pathway related factors transforming growth factor-β, bone morphogenetic protein 7, Smad6 and Smad7 in the liver tissue of rats with hepatic fibrosis. METHODS:SD rats were randomly divided into three groups (n = 10): normal control, model and TanshinoneⅡA-treated groups. Rats in the model and TanshinoneⅡA-treated groups were subtaneously injected with olive oil-diluted 10% CCl4 ( 5 mL/kg) twice a week, 8 weeks in total, to build rat models of hepatic fibrosis. Four weeks after hepatic fibgrosis induction, rats in the TanshinoneⅡA-treated group received subtaneous injection of TanshinoneⅡA til eight weeks. Rats in the normal control group were subcutaneously injected with olive oil. RESULTS AND CONCLUSION: Western blotting and reverse transcription-polymerase chain reaction (RT-PCR) detection showed that in the model group, the expression of transforming growth factor-β in the rat liver tissue was significantly increased (P < 0.01) and the expression of bone morphogenetic protein-7, Smad6 and Smad7 was significantly decreased (P < 0.01) compared with the normal control group. TanshinoneⅡA could obviously reverse the expression of those factors above-mentioned (P < 0.01). The results suggest that TanshinoneⅡA can be used for treatment of hepatic fibrosis by decreasing the expression of transforming growth factor-β and increasing the expression of bone morphogenetic protein-7, Smad6 and Smad7.

ABSTRACT

Objective To verify the relationship between transforming growth factor-β1(TGF-β1) and interleukin-10 (IL-10) in breast milk and allergic diseases development in infants. Methods Totally 191 mothers (99 allergics and 92 controls) and their full-term newborns participated in this prospective study on development of children atopy. Maternal blood, cord blood, colostrum and mature milk were assayed for TGF-β1 and IL-10 by enzyme-linked immunosorbent assay. Infants underwent pediatrician evaluation for allergic diseases at six months old. Concentrations of TGF-β1 and IL-10 from allergic and non-allergic mothers and prevalence of allergic diseases of infants were compared. Results The level of IgE in allergic mothers was 30 750 IU/L(6600-410000 IU/L),lower than that in non-allergic mothers[50000 IU/L(7100-610000 IU/L)](Z=-3. 444,P=0. 001).No difference in the concentration of TGF-β1, IL-10 and IgE in mature milk was observed between allergic and non-allergic mothers. TGF-β1, IL-10 and IgE levels in colostrum of allergic mothers were 2300 pg/ml(620-7000 pg/ml), 12. 8 pg/ml(7.5-560.0 pg/ml)and 7000 IU/L(5100-56000 IU/L),significantly higher than those in non-allergic mothers[1830 pg/ml(1240-9400 pg/ml), 11. 1 pg/ml (7. 2-630.0 pg/ml)and 6700 IU/L(5200-35000 IU/L)] (Z=-2. 215, -2. 730 and -2. 706,P<0.05).In both allergic and non-allergic mothers, TGF-β1 and IL-10 levels in cord blood were higher than those in maternal blood, while IgE was lower. TGF-βl and IL-10 and IgE levels in colostrum were higher than mature milk(P<0.05). At six months old, the prevalence of allergic diseases of infants from allergic mothers(59. 6%, 59/99) was significantly higher than those from non-allergic mothers (21. 7%, 20/92)(x2= 28. 177, P= 0. 000). The prevalence of allergic diseases of infants who completed two weeks' colostrum-fed after birth (44.5 %, 73/164) was significantly higher than those who did not (22.2%,6/27)(x2 =4. 749,P-=0. 029). Conclusions High concentration of TGF-βl and IL-10 in colostrum does not show any protective effect against allergic diseases in infants. The prevalence of allergic diseases of colostrum-fed infants is significantly higher than non colostrum-fed infants, showing that colostrum-fed might play a role in allergic diseases development.

ABSTRACT

Objective To evaluate the plasma levels of adrenomedullin (ADM) and urotensin Ⅱ ( U-Ⅱ ) in children with capillary bronchiolitis, and their clinical significance. Methods One hundred and fifty three children with capillary bronchiolitis and 36 healthy children were recruited. Plasma levels of ADM and U- Ⅱ were measured at acute stage ( <7days) and convalescent stage (>14days) of airway inflammation. The relationship of plasma ADM and U-Ⅱ levels with symptom scores was evaluated. Results Plasma levels of ADM and U-Ⅱ in acute stage of capillary bronchiolitis were significantly higher than those in convalescent stage and healthy controls ( ADM: t = 20. 57 and 26. 26, P < 0. 01; U-Ⅱ: t = 14. 27 and 7. 61, P < 0. 01 ) , and there were significant differences among mild, moderate and severe capillary bronohiolitis (F = 245. 94 and 304. 79, P <0. 01). Plasma level of U-Ⅱ in convalescent stage of capillary bronchiolitis was lower than that of healthy controls (t = 6. 99, P <0. 01 ) , but ADM was still in a higher level ( t = 8. 98, P < 0. 01 ). In the convalescent stage, there was significant difference on U-Ⅱ levels among mild, moderate and severe capillary bronchiolitis ( F = 25.69, P < 0. 01 ) , but no significant difference was observed for ADM levels (F = 2. 25 , P > 0. 05 ) . Plasma levels of ADM and U- Ⅱ in acute stage showed positive correlation with symptom scores, and the regression coefficients were 0.884 (P =0. 000) for ADM and 0. 943 (P = 0. 000) for U-Ⅱ . Conclusion Plasma ADM and U-Ⅱ levels in children with capillary bronchiolitis are increased in acute stage and correlated with the symptom scores, which may serve as laboratory indicators for assessing the severity of the disease.
