Objective: To investigate the efficacy and safety of micafungin (MCF) for pulmonary invasive fungal disease (PIFD) in pediatric patients with acute leukemia or post hematopoietic stem cells transplantation. Method: Twenty-five neutropenic PIFD children with acute leukemia or post hematopoietic stem cells transplantation in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were selected from January 2012 to June 2015, including 12 males and 13 females, age range 2-15 (average 6.2±2.0) years. There were 12 cases of acute leukemia (AL) after chemotherapy, 4 cases of acute leukemia (AL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and 9 cases of β-thalassemia major after allo-HSCT. All children received MCM for the treatment of PIFD, the dosage of MCM was 3-4 mg/ (kg·d) , once a day. The children received 2 to 6 courses of treatment, individually with a course of 7 days. 1, 3-β-D glucan assay (G test), galactomannan antigen test (GM test), high-resolution CT and the biochemical indexes for organ functions were closely monitored. Result: Twenty-five cases were diagnosed as PIFD, including 2 patients diagnosed as proven, 6 as probable and 17 as possible. Of the 25 cases, 1 was confirmed aspergillus by biopsy pathology and 1 was candida albicans by blood culture. The G and GM test with positive results was 5 and 2 respectively. Chest CT scans of the 25 cases had obvious lesions: air crescent sign and cavitation in 4 cases, diffuse ground glass change in 9 cases, double lung scattered patchy, small nodules and cord like high density shadow in 7 cases, unilateral or bilateral chest wall wedge-shaped consolidation edge in 5 cases and pleural effusion in 5 patients. The effective rate of MCF in treatment of PIFD was 68% (17/25), including 13 cases cured, 4 cases improved, 4 cases were improved clinically and in 4 cases the treatment was ineffective. Eight cases were effective in MCF monotherapy group (12 cases) and nine were effective in MCF combined therapy group(13 cases), respectively. Side-effects including allergies, gastrointestinal side effects, electrolyte disturbances, impairment of liver and kidney function, and myelosuppression were not found in those children treated with MCF. Conclusion Micafungin is effective and safe in the treatment of pulmonary invasive fungal disease in pediatric patients with acute leukemia or post hematopoietic stem cell transplantation.

【Objective】 To explore the antidepressant effects of acupuncture at Baihui and Zusanli acupoints on mice with chronic unpredictable mild stress (CUMS)-induced depressive-like behavior and its association with changes in gut microbiota. 【Methods】 Sixty mice were randomly divided into four groups: control group (Ctrl), control+acupuncture group (Ctrl+AP), CUMS group, and CUMS+acupuncture group (CUMS+AP). The CUMS and CUMS+AP groups underwent 6-week CUMS treatment. During the last three weeks of CUMS, mice in the Ctrl+AP and CUMS+AP groups received 20 minutes of acupuncture at Baihui and Zusanli acupoints daily. Sucrose preference test and tail suspension test were used to assess the depressive-like behavior in mice. After the behavioral tests, fecal samples were collected from the mice, and the gut microbiota composition was analyzed using 16S rRNA gene sequencing. 【Results】 Acupuncture alone had no effect on sucrose preference or tail suspension test results in mice (P>0.05). CUMS induced depressive-like behavior in mice, as evidenced by decreased sucrose preference (P<0.001) and increased immobility time in the tail suspension test (P=0.003). The CUMS+AP group showed increased sucrose preference (P=0.035) and decreased immobility time in the tail suspension test (P=0.045) compared to the CUMS group. Acupuncture and CUMS did not alter the richness of gut microbiota in mice (P>0.05), but they caused significant changes in gut microbiota composition (P=0.002). CUMS increased the abundance of six bacterial genera, including Patulibacter, and decreased the abundance of 26 bacterial genera, including Faecalibacterium (P<0.05). The CUMS+AP group showed increased abundance of 10 bacterial genera, including Faecalibacterium, and decreased abundance of four bacterial genera, including Patulibacter, compared to the CUMS group (P<0.05). Each group of mice had specific gut microbiota. The CUMS group showed significant enrichment of gene functions related to retinol metabolism, ubiquitin system, N-glycan biosynthesis, steroid hormone biosynthesis, apoptosis, and thermogenesis compared to the control group (P<0.05), while acupuncture reduced the enrichment of these gene functions in the CUMS+AP mice (P<0.05). 【Conclusion】 Acupuncture at Baihui and Zusanli acupoints has antidepressant effects and can partially restore the depression-induced dysbiosis of gut microbiota. Acupuncture at Baihui and Zusanli acupoints may exert antidepressant effects by influencing gut microbiota composition and metabolism functions of retinol, ubiquitin, N-glycan, and steroids.

OBJECTIVE：To study spectrum-effect relationship of 11 different solvent extracts from Trollius chinensis against hypoxia/reoxygenation injury of cardiomyocyte . METHODS ：HPLC-MS/MS method was used to establish the fingerprints of 11 different solvent extracts from T. chinensis ，the compounds corresponding to the common peaks were identified by comparing with the substance control and literature information. MTT assay was used to detect the effects of 11 different solvent extracts from T. chinensis on the survival rate of rat myocardial H 9c2 cells injured by hypoxia/reoxygenation. The MDA content ，ROS level in cells and LDH content in the supernatant were detected by ELISA. GRA and PLS method were used to analyze the spectrum-effect relationship between the compounds corresponding to common peak and anti-hypoxia/reoxygenation injury of cardiomyocyte （drug effect）. RESULTS ：There were 22 common peaks in 11 different solvent extracts from T. chinensis ，and 22 compounds were identified. Compared with hypoxia/reoxygenation injury group ，survival rate of hypoxia/reoxygenation injury+S 1-S6，S9 and S 10 groups were increased significantly ，while MDA content ，ROS level and LDH content were decreased significantly （P＜0.05）； ROS level and LDH content of hypoxia/reoxygenation injury+S 8 group w ere decreased significantly （P＜0.05）. The r of GRA analysis of 22 compounds with drug effects were all higher than 0.8. Except for peaks 1，2，7，13，14 and 21，r of PLS analysis of rest peaks with drug effects were higher than 0 发。电话：0431-86058683。E-mial：nml2000@163.com （being positive correlation ）. Top 9 common peaks in the list of contribution rate were peak 6＞11＞4＞5＞8＞9＞12＞10＞15.

OBJECTIVETo evaluate antifungal combination strategy in children with hematologic diseases and invasive fungal disease( IFD).

METHODSA retrospective clinical study was performed based on 67 childhood patients with hematologic diseases and IFD who firstly accepted combination antifungal therapy for ≥ 7 days during January 2012 and December 2014. Of them, 11 cases received combination of echinocandin with azole, 10 cases received combination of echinocandin with amphotericin B, and 46 cases received combination of azole with amphotericin B.

RESULTSOverall response rate was 79.1%. Univariate analysis revealed that granulocyte recovery (P=0.031), status of underling disease (P=0.023) and the duration of the therapy (P=0.046) were significantly associated with efficacy. Multivariate analysis showed that the independent prognostic factor was the duration of combination antifungal therapy (OR=0.229, 95% CI 0.061- 0.863, P=0.029). The response rates of echinocandin combined with azole, echinocandin combined with amphotericin B and azole combined with amphotericin B were 81.8%, 60.0% and 82.6%, respectively (P>0.05), and 12-week survival rates were 81.8%, 80.0% and 86.5%, respectively (P>0.05). The drug- related adverse reactions occurred 59 times in 34 patients. BUN increasing, hypokalemia and abnormal liver functions were considered the main side effects.

CONCLUSIONFor IFD in children with hematologic disease, to extend the duration of treatment (≥ 14 days) could significantly improve the curative effect. Combinations of echinocandin with azole, echinocandin with amphotericin B and azole with amphotericin B can be used as a combination treatment options. Combination of Azole with amphotericin B is efficacious, safe and economic treatment option considering efficacy, survival rate, cost and dosage form.
