Acupuncture for prevention of moderate to severe seasonal allergic rhinitis: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the clinical efficacy of acupuncture for prevention of moderate to severe seasonal allergic rhinitis.@*METHODS@#A total of 105 patients with moderate to severe seasonal allergic rhinitis were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). The patients in the observation group were treated with acupuncture at Yintang (GV 24+), Yingxiang (LI 20), Hegu (LI 4), Zusanli (ST 36), Fengchi (GB 20), Feishu (BL 13), etc. 4 weeks before the seizure period, once every other day, 3 times a week for 4 weeks. The patients in the control group were not given any intervention before the seizure period. Emergency drugs can be given appropriately during the seizure period in both groups. After seizure period, the seizure rate was recorded in the two groups; before treatment and on week 1, 2, 4, 6 of seizure period after treatment, the rhinoconjunctivitis quality of life questionnaire (RQLQ) score and total nasal symptom score (TNSS) were observed in the two groups; the rescue medication score (RMS) was recorded on week 1-6 of seizure period in the two groups.@*RESULTS@#The seizure rate of the observation group was 84.0% (42/50), which was lower than 100.0% (48/48) in the control group (P<0.05). After treatment, the scores of RQLQ and TNSS at each time point of seizure period were decreased compared with before treatment in the observation group (P<0.01), which were lower than the control group (P<0.01). The RMS score at each time point of seizure period in the observation group was lower than the control group (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture can reduce the incidence of moderate to severe seasonal allergic rhinitis, relieve the symptoms, improve the quality of life and reduce the use of emergency drugs.

Talking about the key factors to improve the therapeutic effect of acupuncture from "the arrival of ensures curative effect" / 中国针灸

"The arrival of ensures curative effect" reminds us that the key to acupuncture is "the arrival of ". And "arrival of " has the dual meanings of " arriving at the needles" (getting ) and " arriving at the pathogenic locations". " arriving at the needles" is the starting point, the nature and strength of the arrival of is closely related to the efficacy; " arriving at the pathogenic locations" is the end point, so the speed of the is an important part of the final effect. This paper mainly discusses the meaning of the above two aspects and its value in improving the efficacy of acupuncture.

Efficacy and Bleeding Risks of Ticagrelor Replacement for Treating Elderly Acute Coronary Syndrome Patients With Low Response to Clopidogrel / 中国循环杂志

Objective: To observe the efficacy of ticagrelor for treating elderly acute coronary syndrome (ACS) patients with elective PCI and having low response to clopidogrel; to explore the bleeding risks induced by ticagrelor replacement. Methods: A total of 945 ACS patients ≥ 65 years treated in our hospital from 2014-01 to 2017-01 were enrolled. All patients received aspirin and clopidogrel dual antiplatelet therapy (DAPT), thrombelastography (TEG) was used to detect platelet inhibition rate when DAPT ≥ 5 days. Based on platelet inhibition rate, the patients were divided into 2 groups:Ticagrelor replacement group, n=293 patients with low response to clopidogrel and switched to ticagrelor treatment, when adjusted DAPT ≥ 5 days, platelet inhibition rate was rechecked to compare the changes; Clopidogrel group, the patients were continuously treated by the same medication, n=652. The patients were followed-up for 3 months, bleeding events were evaluated by TIMI criteria and compared between 2 groups. Risk factors of ticagrelor induced bleeding were assessed by multivariate Logistic regression analysis. Results: Platelet inhibition rates in Ticagrelor replacement group were (51.70±42.90) %, (48.99±41.85) % and (55.08±25.70) % at (5-7) d, (8-14) d and (15-90) d ticagrelor treatment, which were higher than previous clopidogrel treatment (14.50±24.15) %, all P<0.05. The incidences of severe bleeding events were similar between 2 groups, P=0.96. Multivariate Logistic regression analysis presented that female (OR=4.329, P=0.000), low body weight (OR=0.817, P=0.039) and elevated fasting blood glucose (OR=1.251, P=0.028) were the independent risk factors for bleeding complication in ticagrelor treated elderly ACS patients. Conclusion: Compared with clopidogrel, ticagrelor may faster and more effectively inhibit platelet aggregation without increasing severe bleeding; female, low body weight and elevated fasting blood glucose were the independent risk factors for bleeding complication in ticagrelor treated elderly ACS patients with elective PCI.

Application value of chromosomal microarray analysis in prenatal diagnosis of lateral ventriculomegaly fetuses / 解放军医学杂志

Objective To analyze the genetic etiology of lateral ventriculomegaly fetal on the genome-wide level with chromosomal microarray analysis (CMA),and investigate the relationship between copy number variations (CNVs) and lateral ventriculomegaly and the application value of CMA in prenatal diagnosis of fetuses with lateral ventriculomegaly.Methods Seventy fetuses with lateral ventriculomegaly but normal or uncertain karyotype were selected and invasive prenatal diagnosis was performed in Xi Jing Hospital of the Fourth Military Medical University from Jan.2015 to Nov.2016.Microarray testing was performed using Affymetrix CytoScanTM 750k arrays and the results were analyzed according to biological information science database.The fetal development was regularly inspected,and follow up was conducted to find out the pregnancy outcome and fetal postnatal conditions.Results In 70 cases of lateral ventriculomegaly fetuses,there were 9 fetuses with pathogenic copy number variations (CNVs),3 fetuses with likely pathogenic CNVs and 1 fetus with likely pathogenic 1 oss of heterozygosity (LOH).During the 70 fetuses with lateral ventriculomegaly,2 pathogenic CNVs were detected in 6 fetuses with severe and non isolated lateral ventriculomegaly (33.3％).Pathogenic CNVs was not detected but 1 likely pathogenic CNV was detected in 3 fetuses with severe and isolated lateral ventriculomegaly (33.3％).Six pathogenic CNVs were detected in 31 mild and non isolated lateral ventriculomegaly (19.4％),and 2 likely pathogenic CNVs were also detected in these group (6.5％).One pathogenic CNV and 1 likely pathogenic CNV were detected in 30 fetuses with mild and isolated fetal lateral ventriculomegaly.Conclusions CMA can identify chromosome abnormality microdeletion/microduplication which was unrecognizable by conventional karyotyping analysis.The application of CMA may increase the detection rate of pathogenic CNVs in fetuses with lateral ventriculomegaly,and benefit evaluation of fetal prognosis in prenatal genetic counselling.
