Icaritin is one of the major bioactive compounds of Epimedii Folium. In recent years, scientific and pharmacological studies have shown that icaritin possesses broad therapeutic effects, especially in anti-tumor, enhancing osteoprotective, cardioprotective, neuro-protective function. However, its clinical application was limited by poor water solubility, poor oral absorption and low bioavailability. New drug delivery system has great application prospect in improving solubility of icaritin, oral absorption and bioavailability. Therefore, the current review paper aims to summarize the pharmacological effects of icaritin and briefly introduce some new drug delivery of icaritin, to provide theoretical basis for its clinical application and new drug development.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.

Objective To establish a reproducible mouse model of hepatic veno-occlusive disease (HVOD) after allogeneic bone marrow transplantation (aallo-ABMT) and explore its pathogenesis.Methods Balb/c mice were randomly divided into three groups:(1) normal saline (NS) control group; (2) total body irradiation (TBI) group; (3) allogeneic bone marrow transplantation (allo-BMT) group.Liver weight,total bilirubin (TBil),tumor necrosis factor α (TNF-a),interleukin 6 (IL-6) and monocyte chemotactic protein 1 (MCP-1) were detected on the day 0,5,10,15 and 20 after transplantation.Hepatic vein and sinusoid congestion,infiltration of inflanmatory cells,and damage to hepatic cells and vascular endothelial cells were observed under the light microscopy after HE staining.Fibrosis of hepatic sinusoids and venule was observed under the light microscopy after Masson staining.Results Liver weight and TBil levels were elevated at 5th day and reached the peak at 15th day after all-ABMT.The changes of hepatic congestion and edema were obviously observed and there was infiltration of inflammatory cells at 5th and 10th day after alloABMT.At 15th and 20th day,hepatic congestion,edema and necrosis were reduced and liver damage was mainly presented with liver fibrosis and inflammatory infiltration.All mice died within 10 days after TBI,and hepatic congestion and edema were aggravated.As compared with NS control group,TNF-α,IL-6 and MCP-1 concentrations were significantly increased after all-ABMT.Conclusion A reproducible mouse model of hepatic veno-occlusive disease after all-ABMT was successfully established,and the pathogenesis was closely related to endothelial damage caused by total body irradiation,inflammatory cell infiltration and increased concentrations of cytokines.

OBJECTIVETo study the relationship of the incidence of bronchial dysplasia (bronchial anomalous origin and bronchial stenosis) with congenital heart disease.

METHODSA total of 185 children with congenital heart disease or bronchial dysplasia were enrolled. Bronchial dysplasia was identified by the 64-MSCT conventional scanning or thin slice scanning with three-dimensional reconstruction.

RESULTSForty-five children (25.3%) had coexisting bronchial dysplasia and congenital heart disease. The incidence rate of bronchial dysplasia in children with congenital heart disease associated with ventricular septal defect was higher than in those without ventricular septal defect (33.7% vs 15.0%; P<0.05). There were no significant differences in the incidence rate of bronchial dysplasia between the children with congenital heart disease who had a large vascular malformation and who did not.

CONCLUSIONSBronchial dysplasia often occurs in children with congenital heart disease. It is necessary to perform a tracheobronchial CT scanning with three-dimensional reconstruction to identify tracheobronchial dysplasia in children with congenital heart disease, especially associated with ventricular septal defect.

This study was purposed to investigate the role of monocrotaline-inducing mouse liver sinusoid endothelial cell (SEC) injury in hepatic veno-occlusive disease. BALB/c mice were randomly divided into 2 groups: control group and monocrotaline group, mice were orally administrated with normal saline or monocrotaline with concentration of 200 mg/kg at days 0, 1, 2, respectively. At days 3, 4, 6, 8 and 10 after oral administration with normal saline or monocrotaline, the liver function (ALT, TBIL, AKP) and liver index were examined, and the percentage of activated platelets were detected by flow cytometry. The SEC, vascular endothelial cells and hepatic fibrosis were observed by staining with hematoxylin-eosin and Masson. Transmission electron microscopy was used to observe sinusoidal endothelial cell damage and platelet adhesion. The results showed that compared with control group, mice in monocrotaline group were characterized by severe damage of SEC, numbers of platelet aggregation and adhesion, central number and sinusoidal fibrosis. The percentage of activated platelets and liver index increased (P < 0.05). The characterization of portal hypertension was presented later, such as dysfunction of liver and ascites. It is concluded that SEC injury induced by monocrotaline may be the first step of hepatic veno-occlusive disease, and this kind of SEC injury is self-limiting, but fibrosis is always observed.

[Summary] To explore the therapeutic effect of fecal microbiota transplantation (FMT) for severe psoriasis. A patient, male, 36 years old, diagnosed as severe plaque psoriasis for 10 years and irritable bowel syndrome (IBS) for 15 years, was administrated twice FMT via both upper endoscopy and colonoscopy with a 5‐week interval. The following items were used to evaluate responses: body surface area (BSA), psoriasis area and severity index (PASI), dermatology life quality index (DLQI), histological examination, intestinal symptoms, adverse reactions and serum level of tumor necrosis factor (TNF)‐α. After second FMT treatment for 5 weeks, aforementioned items were improved greatly compared with those before treatment. Moreover, IBS was completely relieved and no adverse reactions were observed during the treatment and follow‐up. In conclusion, FMT could be a novel therapy for psoriasis. Further clinical trials are needed to provide solid evidences.

Objective To compare the clinical efficacy of anti-vascular endothelial growth factor(VEGF)combined with pars plana vitrectomy(PPV)treatment for patients with proliferative diabetic retinopathy(PDR)of different traditional Chinese medicine(TCM)syndrome types in the real world.Methods A prospective real-world study was performed in the 36 patients(involving 42 eyes)with PDR treated by anti-VEGF combined with PPV in the Department of Ophthalmology of the First Affiliated Hospital of Guangzhou University of Chinese Medicine from March 2019 to December 2019.According to the TCM syndrome manifestations,the patients were differentiated as qi-yin deficiency complicated with blood stasis obstructing collaterals type(15 cases,involving 18 eyes;shorten as qi-yin deficiency type),liver-kidney deficiency and ocular collaterals failing in the nourishment type(14 cases,involving 17 eyes;shorten as liver-kidney deficiency type),and yin-yang deficiency complicated with blood stasis and phlegm coagulation type(7 cases,involving 7 eyes;shorten as yin-yang deficiency type).The patients were treated with anti-VEGF therapy first and then received PPV after 5-7 days.Aqueous humor was sampled during anti-VEGF therapy and PPV.After treatment,the efficacy of PDR patients with different TCM syndromes was compared.Moreover,the patients were observed in the best corrected visual acuity(BCVA)of the affected eyes before surgery and 3 months after surgery,levels of cytokines in the aqueous humor before and after anti-VEGF treatment,macular central retinal thickness(CRT),area of the foveal avascular zone(FAZ),the blood density of macular center,inner ring,outer ring and intact macula 3 months after surgery,and the postoperative complications.Results(1)The difference of the therapeutic efficacy of PDR patients with various TCM syndrome types was statistically significant(P＜0.05).Among 3 syndrome types,the best efficacy was found in the qi-yin deficiency type,followed by liver-kidney deficiency type,and then yin-yang deficiency type,with the total efficacy rate being 88.89%(16/18),52.94%(9/17),and 42.86%(3/7),respectively.(2)Three months after surgery,the logarithmic value of minimum angle of resolution(LogMAR)for BCVA of patients with qi-yin deficiency type was significantly superior to that of patients with yin-yang deficiency type,with the difference being statistically significant(P＜0.05).After the anti-VEGF treatment,the levels of cytokines in the aqueous humor of the patients varied in the 3 syndrome types:vascular endothelial growth factor A(VEGF-A)level in the patients with the 3 syndrome types was significantly lower,placental growth factor(PLGF)and angiopoietin-like protein 4(ANGPTL4)levels in the patients with qi-yin deficiency type were higher,and interleukin 8(IL-8)level in the patients with liver-kidney deficiency type was higher than those before treatment,and the differences were statistically significant(P＜0.05 or P＜0.01).The blood density of macular outer ring and intact macula in the patients with qi-yin deficiency type and liver-kidney deficiency type was larger than that in the patients with yin-yang deficiency type,and the differences were statistically significant(P＜0.05).However,the differences of CRT,FAZ area,and blood density of macular center and inner ring among the 3 syndrome types were not statistically significant(P＞0.05).(3)The incidence of postoperative complications in the patients with yin-yang deficiency type was relatively high,but the difference among the 3 syndrome types was not statistically significant(P＞0.05).Conclusion In the real world,the best efficacy of anti-VEGF combined with PPV treatment in PDR patients with different TCM syndrome types can be achieved in the patients differentiated as qi-yin deficiency type,followed by liver-kidney deficiency type,and then yin-yang deficiency type.After anti-VEGF treatment,the levels of cytokines in the aqueous humor of the patients vary in the 3 syndrome types.Three months after the operation,the patients with qi-yin deficiency type and liver-kidney deficiency type have larger blood density of macular outer ring and intact macula,and exert good prognosis.
