Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

This study aims to determine the therapeutic effect and then elucidate the molecular mechanism of Dietary Yangrong Decoction(DYRT)on blood deficiency syndrome based on net-work pharmacology and study its active compounds.The molecular mechanism of DYRT in the treatment of blood deficiency syndrome was predicted by network pharmacology.The blood defi-ciency of rats was established using cyclophosphamide and acetophenohydrazine jointly,which was divided into a blank control group,a model group,a Men's Yangrong Decoction group(MYRT)(positive control group),a medicinal group and food-based Yangrong Decoction group.The active components were analyzed by liquid chromatography-mass spectrometry(HPLC-MS),the periph-eral hemogram was detected by an automatic biochemical analyzer,the levels of hematopoietic regulatory factors in serum were determined by ELISA,and the relative expression of EPO in kid-ney and PI3K,AKT,GM-CSF in bone marrow were measured by RT-PCR.The results showed that DYRT had 57 active ingredients and 128 potential targets for the treatment of spleen deficien-cy syndrome.1 835 items were obtained by GO enrichment analysis,and 20 pathways were ob-tained by KEGG enrichment analysis;DYRT and MYRT were identified by HPLC-MS to contain 12 same blood active compounds.Animal experiments showed that,compared with the model group,the number of red blood cells,the number of platelets and the content of hemoglobin in the DYRT group were significantly increased,and the number of white blood cells was significantly decreased(P＜0.05).The contents of EPO,IL-3,IL-6 and GM-CSF in serum were significantly in-creased,and the content of TNF-α was significantly decreased(P＜0.05).The relative expression levels of EPO in kidney and PI3K,AKT and GM-CSF mRNA in bone marrow were significantly increased(P＜0.05).Compared with the MYRT group,the number of white blood cells in the DYRT group was significantly reduced,the content of GM-CSF in serum was significantly in-creased,and the content of EPO and GM-CSF mRNA was significantly increased(P＜0.05).In conclusion,DYRT contains the same active compounds as MYRT,which can regulate hematopoi-etic factors,thereby activating the PI3K/AKT pathway to restore hematopoietic function and im-prove the blood deficiency state of the body.

Objective: To evaluate the efficacy and safety of compound Lactobacillus acidophilus tablets or Saccharomyces boulardii Sachets combined with standard protocols for eradication of Helicobacter pylori(Hp) in children. Methods: From March 2017 to March 2018, 120 children aged 3-10 years with Hp infection were admitted into the Department of Gastroenterology, Maternal and Child Health Hospital of Hubei Province, including 67 male and 53 female childen.They were divided into 3 groups (control group, compound Lactobacillus acidophilus group, Saccharomyces boulardii Sachets group) by the method of random number table.Control group was given Clarithromycin+ Amoxicillin+ Omeprazole, for 14 days orally; compound Lactobacillus acidophilus group and Saccharomyces boulardii Sachets group were given drugs respectively on the first day, 500 mg of compound Lactobacillus acidophilus was added, twice a day or 250 mg of Saccharomyces boulardii Sachets group, twice a day orally, for 14 days, respectively.The adverse reactions in children were observed during the treatment, andurea ¹³C breath test or the stool Hp antigen test was performed at least 4 weeks by the end of the treatment, and the children with negative results were judged to be eradicated successfully.The ulcer healing, Hp eradication rate and incidence of adverse reactions(nausesa, vomiting, loss of appetite, constipation, diarrhea) among the 3 groups were observed and the Hp eradication rate and the incidence of adverse reactions (nausea, vomiting, loss of appetite, constipation, diarrhea) were compared. Results: The eradication rates in the control group, the compound Lactobacillus group, and Saccharomyces boulardii Sachets group were 80.0% (32/40 cases), 85.0% (34/40 cases), and 87.5% (35/40 cases), respectively, and the difference was not statistically significant (P=0.646); the ulcer healing rate was 100.0% of 101 Hp eradicators in 3 groups, and the ulcer healing rate of 19 cases without Hp eradicated was 48.15%, and there was a significant difference between them (χ²=51.30, P<0.01). However, there was no significant difference in the total effective rate among 3 groups (P>0.05). The overall incidence of adverse reactions in Saccharomyces boulardii Sachets group (P=0.021) and the incidence of diarrhea (P=0.002) and loss of appetite (P=0.021) was lower than that in the control group, and the differences were statistically significant.There was no significant difference in the incidence of adverse reactions between the two probiotic groups (P>0.05). Conclusions Both compound Lactobacillus acidophilus tablets and Saccharomyces boulardii Sachets group can reduce the overall incidence of adverse reactions and the incidence of diarrhea and appetite declines in children′s standard Hp eradication regimen without affecting Hp eradication rate.

OBJECTIVE: To determine the feasibility of reduced field-of-view diffusion-weighted imaging (rFOV DWI) with multi-b values to detect functional variability in transplanted kidneys. MATERIALS AND METHODS: Using a 3T MRI scanner, multi-b rFOV DWI of transplanted kidney or native kidney was performed in 40 renal transplantation recipients and 18 healthy volunteers. The patients were stratified, according to an estimated glomerular filtration rate (eGFR): Group 1, eGFR ≥ 60 mL/min/1.73 m2; Group 2, eGFR ≥ 30 mL/min/1.73 m2 and < 60 mL/min/1.73 m2; Group 3, eGFR < 30 mL/min/1.73 m2. Total apparent diffusion coefficient (ADCT), perfusion-free ADC (ADCD) and perfusion fraction (FP) of kidneys were calculated and compared among the four groups. Correlations between the imaging results and eGFR were assessed. RESULTS: All volunteers had eGFR ≥ 60 mL/min/1.73 m2, while 16, 16, and 8 patients were included in Groups 1, 2, and 3, respectively. In the renal cortex, ADCT was higher in Group 1 ([1.65 ± 0.13] × 10−3 mm2/s) than Group 3 ([1.44 ± 0.11] × 10−3 mm2/s) (p < 0.05), and the inter-group differences of FP values were significant (all p < 0.05) (0.330 ± 0.024, 0.309 ± 0.019, 0.278 ± 0.033, and 0.250 ± 0.028 for control group, Groups 1, 2, and 3, respectively). Renal cortical ADCT, ADCD, FP, and renal medullary ADCT and FP correlated positively with eGFR (r = 0.596, 0.403, 0.711, 0.341, and 0.323, respectively; all p < 0.05). When using 0.278 as the cutoff value, renal cortical FP had a sensitivity of 97.1% and a specificity of 66.7% for predicting decreased renal function. CONCLUSION: Multi-b rFOV DWI presents transplanted kidneys with high resolution, which is a promising functional tool for non-invasively monitoring function of transplanted kidneys.
