Changes of intestinal flora in children with acute lymphoblastic leukemia before and after chemotherapy / 中国当代儿科杂志

OBJECTIVES@#To examine the changes of intestinal flora in children newly diagnosed with acute lymphoblastic leukemia (ALL) and the influence of chemotherapy on intestinal flora.@*METHODS@#Fecal samples were collected from 40 children newly diagnosed with ALL before chemotherapy and at 2 weeks, 1 month, and 2 months after chemotherapy. Ten healthy children served as the control group. 16S rDNA sequencing and analysis were performed to compare the differences in intestinal flora between the ALL and control groups and children with ALL before and after chemotherapy.@*RESULTS@#The ALL group had a significant reduction in the abundance of intestinal flora at 1 and 2 months after chemotherapy, with a significant reduction compared with the control group (P<0.05). Compared with the control group, the ALL group had a significant reduction in the diversity of intestinal flora before and after chemotherapy (P<0.05). At the phylum level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Actinobacteria at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05) and a significant increase in the relative abundance of Proteobacteria at 1 and 2 months after chemotherapy (P<0.05). At the genus level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Bifidobacterium at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05); the relative abundance of Klebsiella in the ALL group was significantly higher than that in the control group at 1 and 2 months after chemotherapy and showed a significant increase at 1 month after chemotherapy (P<0.05); the relative abundance of Faecalibacterium in the ALL group was significantly lower than that in the control group before and after chemotherapy and showed a significant reduction at 2 weeks and 1 month after chemotherapy (P<0.05). The relative abundance of Enterococcus increased significantly at 1 and 2 months after chemotherapy in the ALL group (P<0.05), and was significantly higher than that in the control group (P<0.05).@*CONCLUSIONS@#The diversity of intestinal flora in children with ALL is significantly lower than that in healthy children. Chemotherapy significantly reduces the abundance of intestinal flora and can reduce the abundance of some probiotic bacteria (Bifidobacterium and Faecalibacterium) and increase the abundance of pathogenic bacteria (Klebsiella and Enterococcus) in children with ALL.

Therapeutic Observation of Continuous Subcutaneous Insulin Infusion at Acupoint for Type 2 Diabetes / 上海针灸杂志

Objective To observe the difference between continuous subcutaneous insulin infusion (CSII) at acupoint and CSII at non-acupoint in treating type 2 diabetes, for providing a novel option in selecting the insulin injection site. Method Sixty-six subjects with type 2 diabetes were randomized into a treatment group of 32 cases and a control group of 34 cases. The treatment group was intervened by CSII at acupoint, while the control group was intervened by CSII at non-acupoint. The body mass index (BMI), fasting plasma glucose (FPG), 2 h-postprandial plasma glucose (P2hPG), bedtime blood sugar, glycated hemoglobin (HbA1c), consumption of insulin, and the score of diabetes symptom grading and quantification of the two groups were compared. Result The blood sugar level, insulin consumption, HbA1c level and symptom score declined significantly after treatment in both groups (P<0.05);the BMI and initial dosage of insulin in the treatment group dropped significantly after treatment in the treatment group (P<0.05); after treatment, the BMI, FPG level, initial dosage of insulin and symptom score in the treatment group were markedly lower than those in the control group (P<0.05); there were no significant differences between the treatment group and the control group in the P2 hBG level, bedtime glucose sugar level, HbA1c level, pre-prandial insulin dose and total effective rate (P>0.05). Conclusion CSII at acupoint and at non-acupoint both can effectively improve the disease condition of type 2 diabetes. The treatment group is superior to the control group in controlling BMI and FPG, reducing the initial level of insulin, and improving the symptoms, and the treatment group presents a higher total effective rate with the increase of treatment duration compared with the control group. It is indicated that insulin infusion at abdominal acupoint has a certain advantage in the treatment of type 2 diabetes.

Efficacy of acupuncture and moxibustion in treating Bell's palsy: a multicenter randomized controlled trial in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Bell's palsy involves acute facial paralysis due to inflammation of the facial nerve. Acupuncture and moxibustion (acu-moxi) is beneficial in treating facial palsy. In order to verify the efficacy of acu-moxi on Bell's palsy, a randomized single-blind, multicenter clinical trial was performed.</p><p><b>METHODS</b>A total of 480 patients from four clinical centers were involved in this trial, of whom 439 completed the trial and 41 did not. All patients were randomly assigned to either the control group or to one of two treatment groups. The control group was treated with prednisone, vitamin B1, vitamin B12, and dibazole; the treatment groups were treated either with acu-moxi alone or in combination with prednisone, Vitamin B1, vitamin B12, and dibazole. Symptoms and signs, the House-Brackmann scale, and facial disability index (FDI) scores were assessed and determined both pre- and post-treatment to evaluate the effectiveness of the treatment methods.</p><p><b>RESULTS</b>The characteristics of the control and two treatment groups were comparable without statistically significant differences before treatment. There were significant differences between the control and treatment groups after treatment (chi(2) = 15.265, P = 0.018). According to evaluations based on the House-Brackmann scale and FDI scores, the effectiveness of treatment in the two treatment groups was better than in the control group and was most effective in patients receiving acu-moxi treatment alone (Z = -2.827, P = 0.005).</p><p><b>CONCLUSION</b>The efficacy of acu-moxi treatment for Bell's palsy is verified scientifically.</p>
