ObjectiveThrough the correlation analysis between intestinal absorption profile and inhibition of macrophage foaming， the pharmacodynamic components of Zhuriheng dripping pills（ZRH） were explored to provide a basis for establishing its quality standard. MethodIntestinal absorption fluids with 0， 5， 10， 15， 20 times clinical equivalent doses were prepared by a rat everted gut sac（EGS）， and the oxidized low density lipoprotein（ox-LDL）-induced RAW264.7 macrophage foaming model was used to investigate the effect of intestinal absorption fluid with different doses on the accumulation of lipids in RAW264.7 cells by oil red O staining and cholesterol content determination， and to screen for the optimal dose. Ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS） was used to analyze and identify intestinal absorption fractions of ZRH intestinal absorption fluids， and partial least squares-discriminant analysis（PLS-DA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were performed on different doses of ZRH intestinal absorption fluids using SIMCA 13.0 with peak area as the independent variable and the pharmacodynamic indicators as the dependent variables to screen the compounds with variable importance in the projection（VIP） value>1.0 as contributing components， and Pearson correlation analysis was used to determine the spectral effect relationship， determined the compounds and positive correlation with pharmacodynamic were as active ingredients. Molecular docking was used to verify the binding energy of peroxisome proliferator-activated receptor α（PPARα）， PPARγ， PPARβ， human retinoid X receptor α（RXRA） and nuclear transcription factor-κB（NF-κB） with the active ingredients in ZRH intestinal absorption fluids. Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was performed to detect the mRNA levels of PPARγ， scavenger receptor A1（SRA1） and adenosine triphosphate-binding cassette transporter A1（ABCA1） in RAW264.7 cells， Westen blot was used to detect the expression level of PPARγ protein in RAW264.7 cells， and enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of interleukin（IL）-1β and NF-κB in RAW264.7 cells. ResultAccording to the results of oil red O staining and cholesterol content determination， the ZRH intestinal absorption fluids could significantly reduce macrophage foaming， and intestinal absorption fluids with 15， 20 times clinical equivalent doses had the best effect， the 15-fold ZRH intestinal absorption fluid was finally determined as the study subject. Spectral effect relationship showed that 52 corresponding peaks in the ZRH-containing intestinal fluid were positively correlated with the efficacy， including organic acids， phenylpropanoids， iridoids， flavonoids， bile acids， coumarins and chromones. Target validation results showed that 86.9%-96.2% of the total components processed good binding activities with the key targets of PPARα， PPARγ， PPARβ， RXRA and NF-κB， and the docking energy values were all less than -6.0 kcal·mol^-1（1 cal≈4.19 J）. The results of validation showed that， compared with the normal group， the model group showed a significant increase in the levels of SRA1 and PPARγ mRNA expression， a significant decrease in ABCA1 mRNA expression， a significant increase in the level of PPARγ protein expression， and a significant increase in the levels of IL-1β and NF-κB（P<0.01）， compared with the model group， the 15-fold intestinal absorption fluid group showed a significant decrease in the levels of SRA1 and PPARγ mRNA expression（P<0.05， P<0.01）， ABCA1 mRNA expression level was significantly up-regulated， the levels of IL-1β and NF-κB were significantly reduced（P<0.01）， and PPARγ protein expression level was significantly reduced（P<0.05）. ConclusionThis study identifies 52 components and their metabolites in ZRH intestinal absorption fluid that are positively correlated with the inhibition of macrophage foaming， which may be related to the regulation of the PPARs pathway in cells and the reduction of the levels of inflammatory factors， and can provide a reference for the quality control and clinical application of ZRH.

Objective:To observe the clinical efficacy of exercise-based acupuncture in treating ischemic stroke and its effects in improving the patient's motor function and daily living ability. Methods:A total of 106 patients with motor dysfunction due to cerebral infarction were randomized into a trial group and a control group,each consisting of 53 cases.Both groups received conventional rehabilitation;in addition,the control group was given point-toward-point acupuncture at scalp points,and the trial group was offered exercise-based acupuncture,3 times weekly for 4 consecutive weeks.Before treatment,after 2 and 4 weeks of treatment,and at the 2-month follow-up,the Fugl-Meyer assessment(FMA)scale,Lovett scale for muscle strength,modified Ashworth scale(MAS),and activities of daily living(ADL)scale were used to assess the patient's motor function,muscle strength,muscle tension,and daily living ability. Results:After treatment,both groups gained improvements in motor function and daily living ability;after 4-week treatment and at the 2-month follow-up,the trial group had higher FMA and ADL scores than the control group(P<0.05).The MAS score decreased after treatment in both groups;after 2 and 4 weeks of treatment and at the 2-month follow-up,the MAS score was lower in the trial group than in the control group(P<0.05).After the intervention,the Lovett score increased in both groups;after 4 weeks of treatment,the Lovett score was higher in the trial group than in the control group(P<0.05). Conclusion:Based on routine rehabilitation,exercise-based acupuncture and scalp point-toward-point acupuncture both can improve the motor function and daily living ability in ischemic stroke patients;exercise-based acupuncture performs better than scalp point-toward-point acupuncture.

The solute carrier family 12(SLC12)of cation-chloride cotransporters(CCCs)comprises potassium chlo-ride cotransporters(KCCs,e.g.KCC1,KCC2,KCC3,and KCC4)-mediated Cl-extrusion,and sodium po-tassium chloride cotransporters(N[K]CCs,NKCC1,NKCC2,and NCC)-mediated Cl-loading.The CCCs play vital roles in cell volume regulation and ion homeostasis.Gain-of-function or loss-of-function of these ion transporters can cause diseases in many tissues.In recent years,there have been considerable ad-vances in our understanding of CCCs'control mechanisms in cell volume regulations,with many tech-niques developed in studying the functions and activities of CCCs.Classic approaches to directly measure CCC activity involve assays that measure the transport of potassium substitutes through the CCCs.These techniques include the ammonium pulse technique,radioactive or nonradioactive rubidium ion uptake-assay,and thallium ion-uptake assay.CCCs'activity can also be indirectly observed by measuring y-aminobutyric acid(GABA)activity with patch-clamp electrophysiology and intracellular chloride con-centration with sensitive microelectrodes,radiotracer 36Cl-,and fluorescent dyes.Other techniques include directly looking at kinase regulatory sites phosphorylation,flame photometry,22Na+uptake assay,structural biology,molecular modeling,and high-throughput drug screening.This review sum-marizes the role of CCCs in genetic disorders and cell volume regulation,current methods applied in studying CCCs biology,and compounds developed that directly or indirectly target the CCCs for disease treatments.

Results:A total of 1 503 valid questionnaires were collected, the assessment scores of theory knowledge, skill mastery and overall self-efficacy were (53.11±12.34), (62.64±18.35) and (6.09±2.18) points; According to demographic characteristics, multiple linear regression indicated that the influence factors of theory knowledge and skill mastery assessment scores included age, occupational distribution, education backgrounds, training conditions, time of taking training to survey, "onlooker" experience and self-efficacy indicators ( t/ F values were 5.723, 4.393, 5.817, 6.435, 5.990, 6.438, 6.631, P<0.01). The positive correlations were assumed ( r values were 0.012, 0.016, P<0.05) . Conclusion:In Ningxia, the inhabitants generally have low theory knowledge, skill mastery and self-efficacy levels. Therefore, the relevant medical institutions shall enhance the inhabitants ′ cardio-pulmonary resuscitation training through multiple methods and approaches.

Objective:To investigate the influencing factors of hospitalization expenses in high-rate cases, and provide scientific basis for targeted cost control.Methods:The first page data of 79 929 discharged medical records of a tertiary hospital in Ningxia Hui Autonomous Region in 2018 were selected for DRG analysis and evaluation. The average total hospitalization expenses of the same DRG group in the same level and similar hospitals in Ningxia were taken as the benchmark cost to calculate the benchmarking ratio of each DRG group. GM grey correlation method was applied to analyze the correlation between each sub-item cost and the total hospitalization cost of each DRG group, and the logistic regression was used to analyze the influencing factors of high-rate cases.Results:There were 1 292 high-rate cases, accounting for 1.64% of 78 789 DRG-incorporated cases. The results of grey correlation analysis showed that among the 10 high-rate DRG groups, the correlation order of drug cost in 6 DRG groups was the first, and that of consumables cost was the first in 2 DRG groups; logistic regression results showed that age group( P=0.010), actual hospital stay( P<0.001), and mode of leaving hospital( P<0.001) were the influencing factors of high-rate cases. Conclusions:Drug costs, consumables costs, and length of stay have great influence on the hospitalization costs for high-rate cases, which should be paid particular attention to.

Objective:To explore the application value of primary trauma treatment (PTC) teaching mode in special professional cardiopulmonary resuscitation (CPR) guide training.Methods:Cluster sampling method was adopted, and the residents' committee selected special occupation population from every town/sub-district office in the southern mountainous area of Ningxia Hui Autonomous Region for CPR training. A monthly session was held from January to December 2019, with personnel trained by traditional operation teaching and individual practice method from January to June 2019 as the control group and personnel trained by PTC teaching mode from July to December 2019 as the observation group. The two groups of trainers, training objectives and assessment standards were consistent. Questionnaire survey was conducted at the beginning and end of each training period, including the degree of mastery of first-aid knowledge and skills and the level of self-efficacy, etc., to evaluate the training effect.Results:There were 503 trainees in each group, and there was no significant difference in gender, age, education and occupation distribution between the two groups. There was no significant difference in the first aid principles, CPR skill level and self-efficacy between the two groups before the training. The first aid principle, CPR skills level and self-efficacy of the two groups after training were all improved, and the principle of first aid and CPR skills level in the observation group was obviously higher than that in the control group (first aid related concepts: 4.39±0.76 vs. 3.87±0.89, gold life-saving time: 5.71±0.49 vs. 4.53±0.62, the meaning of the first witnesses: 5.33±0.82 vs. 4.18±0.78, cardiac, respiratory cardiac arrest in the judgment: 5.12±0.73 vs. 4.07±0.73, CPR skills: 5.29±0.64 vs. 4.15±0.71, all P < 0.05). The self-efficacy score of the observation group was significantly higher than that of the control group (emergency attitude: 18.17±1.24 vs. 17.35±1.25, self-efficacy: 13.56±1.54 vs. 11.35±1.26, behavioral intention: 9.56±0.84 vs. 8.92±0.95, all P < 0.05). Conclusion:The application of PTC teaching mode in the training of CPR guidelines for special professions has significant effects, which can effectively help special professions to master CPR knowledge and skills, and has promotion value.

Objective:To analyze the spatial-temporal distribution characteristics of human brucellosis (HB) in Ningxia Hui Autonomous Region (Ningxia) from 2012 to 2018 and the correlation between HB and the number of livestock stocks, so as to provide reference for the development of preventive measures.Methods:Data on the incidence of HB was collected from the Infectious Disease Report Information Management System of Ningxia, 2012 to 2018. Data related to HB incidence in Ningxia from 2012 to 2018 was then analyzed by global spatial autocorrelation and local spatial autocorrelation analysis methods through the geographic information system (GIS). SPSS (23.0) Spearman correlation was used to analyze the correlation between the incidence of HB and the number of cattle, sheep and pigs.Results:From 2012 to 2018, the incidence of HB showed an overall increase in Ningxia, with an annual growth in 2012-2015 but declined between 2015 and 2018. Results from the global autocorrelation analysis showed that the distribution of HB in the counties and districts of Ningxia appeared non-randomly, with Moran’s I value as positive in 2012, 2013 and 2016 indicating the distribution was positive in space. Through local autocorrelation analysis, results showed that "H-H" concentration area was mainly concentrated in central while the "L-L" concentration area was mainly in the northern part of Ningxia. As for the results from correlation analysis between HB and animal husbandry, it showed that the incidence of HB was positively correlated with the number of sheep in stock ( r=0.692, P=0.000). Conclusions:The epidemic situation of HB expressed different degrees of aggregation. Areas with high incidence were mostly concentrated in central Ningxia, and with certain degree of correlation with the number of sheep in stock. Corresponding measures should be taken to control the different aggregation situation. Programs on quarantine and immunization for sheep should also be strengthened.
