Patients' expectancy scale of acupuncture: Development and clinical performance test.

PURPOSE: This study aims to develop and validate a concise tool for evaluating acupuncture expectancy that is easy to understand and conforms to acupuncture characteristics. MATERIALS AND METHODS: A draft was created using the Delphi consensus method. Reliability, validity, discrimination, and feasibility tests were conducted at the item and scale levels. RESULTS: The scale themes were defined as disease-related, treatment-related, process-related, and outcome-related. After two rounds of Delphi surveys with good experts' reliability (authority coefficients of experts were 0.86 and 0.87 in the two rounds) and agreement (Kendall's concordance coefficient of the participants were 0.33 and 0.15 in the two rounds, P < 0.05), 11 items (the mean score for item importance, full mark ratios, and coefficient of variation of items were ≥3.5, ≥25%, and ≤0.30, respectively) were included in the draft. A total of 145 individuals were recruited to test the draft. Reliability was assessed by Cronbach's α coefficient (0.90), split-half reliability coefficient (0.89), and test-retest reliability (Pearson's coefficient = 0.74, P < 0.05). Content validity was assessed by the content validity index (Item-CVI ≥ 0.78 and Scale-CVI/Ave = 0.92), and a confirmatory factor analysis was performed to assess the construct validity. The discrimination of scale items was evaluated by the critical ratio (CR > 3.00) and the homogeneity test (item-total correlations >0.40). Feasibility was assessed through the acceptance rate (recovery rate = 98.60%, response rate = 100%), completion rate (100%), and completion time (4.99 ± 6.80 min). CONCLUSION: The patients' expectancy scale of acupuncture (PESA) consists of 11 items with four themes, disease-related, treatment-related, process-related, and outcome-related. It has great reliability, validity, discrimination, and feasibility and has the potential to evaluate acupuncture expectancy in clinical trials.

[Effect of Deep Vertical Rotary Tillage on Soil Bacterial Community Diversity and Microbial Network Structure in Cultivated Land].

The aim of this study was to understand the effect of deep vertical rotary tillage on the diversity and structural distribution of a soil bacterial community in cultivated land, as well as the interactions between microbial ecological molecular network and species. In this study, the cultivated soil under different tillage methods in the Yellow River diversion irrigation area in Ningxia was selected as the research object, and two treatments were set up, namely, deep vertical rotary tillage (DVRT) and conventional tillage (CT). Then, Illumina MiSeq technology was used to analyze the molecular ecological network of soil bacterial community under different tillage methods in the Ningxia Yellow River irrigation area. The results showed that DVRT significantly increased the contents of total organic carbon (TOC), total nitrogen (TN), alkali-hydrolyzed nitrogen (AN), total phosphorus (TP), available phosphorus (AP), and total potassium (TK) in the 0-20 cm soil layer compared with those in the CT treatment. Compared with those in the CT treatment, DVRT significantly increased the contents of TOC, TN, TP, AP, TK, and available potassium (AK) in the 20-40 cm soil layer. DVRT treatment significantly increased water content (WC) by 8.13%-13.30% and decreased pH and electrical conductivity (EC) by 4.51%-5.85% and 12.5%-13.33%, respectively. In different growth stages and soil layers of maize, the Shannon and Ace indices were increased in the DVRT treatments. The dominant bacterial phyla were:Actinobacteria, Proteobacteria, Chloroflexi, Acidobacteriota, and Gemmatimonadota. The results of bacterial community ß diversity showed that DVRT and CT had significant differences in bacterial community structure. The redundancy analysis and Partial Mantel test results showed that pH, EC, and TP were the key environmental factors affecting the structural diversity of bacterial communities. Molecular ecological network analysis revealed that DVRT treatment microbial networks consisted of more functionally related microbial modules, and the topological roles of key microorganisms were different from those in the CT treatment. In conclusion, DVRT can enhance soil nutrients and WC in different soil layers, reduce pH and EC, improve soil bacterial community diversity and microbial network structure, and also enhance the potential ecosystem functions in cultivated soil.

The efficacy and safety of intravenous sucrose iron therapy for recurrent iron deficiency anemia / 中华血液学杂志

Objective: To evaluate the efficacy and safety of intravenous iron supplementation in patients with recurrent iron deficiency anemia (IDA) . Methods: This retrospective analysis of 90 patients with recurrent IDA from May 2012 to December 2021 was conducted, comparing the efficacy and safety of the intravenous iron therapy group and the oral iron therapy group. Results: Among the 90 patients with recurrent IDA, 20 were males and 70 were females, with a median age of 40 (range: 14-85) years. A total of 60 patients received intravenous iron supplementation and 30 received oral iron supplementation. The hematologic response rates in the intravenous iron group were significantly higher than those in the oral iron group at 4 and 8 weeks after treatment [80.0% (48/60) vs 3.3% (1/30) and 96.7% (58/60) vs 46.7% (14/30), all P<0.001, respectively]. The median increase in hemoglobin levels was also significantly higher in the intravenous iron group than in the oral iron group [38 (4, 66) g/L vs 7 (1, 22) g/L at week 4 and 44.5 (18, 80) g/L vs 19 (3, 53) g/L at week 8, all P<0.001]. The intravenous iron group had a significantly higher proportion of patients who achieved normal hemoglobin levels than the oral iron group (55.0% vs 0 and 90% vs 43.3%, all P<0.001, respectively). Iron metabolism indicators were tested before and after 8 weeks of treatment in 26 and 7 patients in the intravenous and oral iron groups, respectively. The median increase in serum ferritin (SF) levels in the intravenous iron group 8 weeks after treatment was 113.7 (49.7, 413.5) μg/L, and 54% (14/26) of these patients had SF levels of ≥100 μg/L, which was significantly higher than the median increase in SF levels in the oral iron group [14.0 (5.8, 84.2) μg/L, t=4.760, P<0.001] and the proportion of patients with SF levels of ≥100 μg/L (P=0.013). The incidence of adverse reactions was 3.3% (2/60) in the intravenous iron group, which was significantly lower than that in the oral iron group [20.0% (6/30), P=0.015]. Conclusion: Intravenous iron supplementation is more effective for hematologic response, faster hemoglobin increase, and higher iron storage replenishment rates compared with oral iron supplementation in patients with recurrent IDA, and it is well tolerated by patients.

Effect of fast restoration of aquatic vegetation on phytoplankton community after removal of purse seine culture in Huayanghe Lakes.

The disappearance of submerged aquatic vegetation caused by the use of purse seine in productive fishery has aroused the attention of the national government. In order to restore aquatic vegetation, the government has removed the seine nets on the Huayanghe Lake's surface. Here, fourteen cruises were conducted in the Huayanghe Lakes from 2016 to 2019 to study the response of water quality and phytoplankton communities to rapidly recovering aquatic vegetation. The results showed that the restoration of aquatic vegetation increased the Secchi depth (from 65.36 to 105.52 cm) and dissolved oxygen (from 8.98 to 12.17 mg/L), while the concentration of total nitrogen (from 0.98 to 0.53 mg/L), and total phosphorus (from 0.04 to 0.02 mg/L) decreased, resulting in a 35.3% and 11.6% reduction in the total phytoplankton density and chlorophyll ɑ, respectively. In addition, the restoration of aquatic vegetation significantly increased Shannon-Wiener diversity, Margalef richness indices by 51.6% and 40.1%. We also observed that phytoplankton density exhibited significant changes based on nonmetric multidimensional scaling analysis (NMDS). In Lake Huangda, the coverage of aquatic vegetation was as high as 80%. We also observed that after the restoration of aquatic vegetation, the proportion of cyanobacteria decreased significantly by 21%. Our study emphasizes that aquatic plants can alleviate eutrophication and increase the diversity of phytoplankton, thus providing guidance for the restoration and protection of water ecosystems in the lakes connected to the Yangtze River.

Effect of Huai Qi Huang on asthma in rats and the mechanism research / 中国当代儿科杂志

OBJECTIVE@#To study the role and mechanism of action of Huai Qi Huang (HQH) in the rat model of asthma.@*METHODS@#Forty Sprague-Dawley rats were randomly divided into a control group, an asthma model group, a budesonide group, and an HQH group, with 10 rats in each group. A rat model of asthma was established by ovalbumin sensitization and challenge. The budesonide group was given budesonide aerosol 2 mg before each challenge. The HQH group was given HQH 4 g/kg dissolved in water by gavage before each challenge. Hematoxylin and eosin staining was used to observe the pathological changes of lung tissues. The percentage of eosinophils in bronchoalveolar lavage fluid (BALF) was measured. Enzyme-linked immunosorbent assay was used to determine the levels of interleukin-3 (IL-3), interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-10 (IL-10), interferon gamma (INF-γ), and immunoglobulin E (IgE) in BALF. Flow cytometry was used to determine T-helper type 1 (Th1)/T-helper type 2 (Th2) ratio in peripheral blood and the spleen. RT-PCR and Western blot were used to measure the mRNA and protein expression of T-bet and GATA-3 in lung tissue.@*RESULTS@#Compared with the control group, the asthma model group showed significant increases in the degree of airway inflammation, the percentage of eosinophils in BALF, and the levels of IL-3, IL-4, IL-5 and IgE in BALF (P<0.05), however, the asthma model group showed significant reductions in the levels of IL-10 and INF-γ in BALF (P<0.05). The asthma model group had significantly lower percentage of Th1 cells but significantly higher percentage of Th2 cells in peripheral blood and the spleen compared with the control group (P<0.05). The mRNA and protein expression of T-bet in lung tissue was significantly lower, but the mRNA and protein expression of GATA-3 in lung tissue was significantly higher in the asthma group than those in the control group (P<0.05). Both HQH and budesonide significantly improved airway inflammation and the above markers in asthmatic rats (P<0.05), with comparable effects between them. However, there were still significant differences in these indices between the control group and the HQH or budesonide group (P<0.05).@*CONCLUSIONS@#HQH can reduce the airway inflammation of asthmatic rats and alleviate the symptoms of asthma, possibly by regulating the levels of related cytokines and Th1/Th2 ratio through the T-bet/GATA-3 pathway.

The regulatory effect of electro-acupuncture on the expression of NMDA receptors in a SCI rat model.

BACKGROUND: In early spinal cord injury (SCI), glutamate receptors, including N-methyl-d-aspartate (NMDA) receptors (NMDARs), are over-stimulated by excessively released glutamate. The enhanced activity of NMDARs may cause cell death by overloading calcium (Ca2+) into cells based on their high permeability to Ca2+. Studies in SCI animals have shown that treatment with electro-acupuncture (EA) is able to reduce cell death and to improve functional recovery. One possible mechanism of this neuroprotective effect is that EA has regulatory effect on NMDARs. AIMS: To test whether EA could protect the spinal cord after SCI by decreasing the expression levels of NR1 and NR2A. MAIN METHODS: We conducted EA treatment on a rat SCI model produced with a New York University (NYU) Impactor and measured hindlimb locomotor function by Basso, Beattie and Bresnahan Locomotor Rating Scale (BBB Scale). The expression of NR1 and NR2, the subunits of NMDARs, in the injured spinal cord was measured by Immunofluorescence stainings, western blot and real-time quantitative PCR (RT-qPCR). KEY FINDING: Our results showed that two days after the SCI the expression of NR1 and NR2 were dramatically enhanced at both protein and mNRA levels, which were significantly reduced by EA treatment at two specific acupoints, Dazhui (DU14) and Mingmen (DU4). SIGNIFICANCE: EA is a potential therapeutic method for treating early SCI in human.

Promoting blood circulation for removing blood stasis therapy for acute intracerebral hemorrhage: a systematic review and meta-analysis.

AIM: To conduct a systematic review and meta-analysis to assess the current evidence available regarding the promoting blood circulation and removing blood stasis (PBCRBS) therapy for Chinese patients with acute intracerebral hemorrhage (ICH). METHODS: Six databases were searched from their inception to November 2013. The studies assessed in ≥ 4 domains with 'yes' were selected for detailed assessment and meta-analysis. The herbal compositions for PBCRBS therapy for acute ICH patients were also assessed. RESULTS: From the 6 databases, 292 studies claimed randomized-controlled clinical trials (RCTs). Nine studies with 798 individuals were assessed in ≥ 4 domains with 'yes' by using the Cochrane RoB tool. Meta-analysis showed that PBCRBS monotherapy and adjuvant therapy for acute ICH could improve the neurological function deficit, reduce the volume of hematoma and perihematomal edema, and lower the mortality rate and dependency. Moreover, there were fewer adverse effects when compared with Western conventional medication controls. Xueshuantong Injection and Fufang Danshen Injection, Buyang Huanwu Decoction and Liangxue Tongyu formula, and three herbs (danshen root, sanqi and leech) were the most commonly used Chinese herbal patent injections, herbal prescriptions and single herbs, respectively. CONCLUSION: Despite the apparently positive findings, it is premature to conclude that there is sufficient efficacy and safety of PBCRBS for ICH because of the high clinical heterogeneity of the included studies and small number of trials in the meta-analysis. Further large sample-sizes and rigorously designed RCTs are needed.

Cultural anthropology of traditional Chinese medicine / 中西医结合学报

Biological, psychological and sociological model of medicine substantializes the old model lacking the social humane attributes. The new medical model makes people take medical anthropology into research and highly evaluate traditional medical system. Cultural anthropology of traditional Chinese medicine (TCM) is part of medical anthropology with three major characteristics: wide research scope, specificity, and integration. It has developed its own research methods, such as field investigation, comprehensive inspection and comparison study. Cultural anthropology provides an efficient research method for TCM, and its application would further develop TCM theory and form comprehensive evaluation on TCM effects.
