ObjectiveTo observe the clinical effect of Xijiao Dihuangtang combined with acupuncture on the treatment of systemic lupus erythematosus （SLE） with syndrome of intense heat toxin. MethodA total of 102 cases of SLE with syndrome of intense heat toxin （admitted from January 2020 to December 2021） were divided into a control group and an observation group by random number table method， with 51 cases in each group. Patients in the control group received conventional western medicine treatment （hydroxychloroquine sulfate + poonisone acetate tablets）. Patients in the observation group were given Xijiao Dihuangtang combined with acupuncture based on the treatment of the control group. Clinical efficacy， onset time， symptom improvement time， skin lesion regression time， and hospital stays were recorded. Blood routine index change， 24 h urine protein levels， double-stranded DNA （ds-DNA） antibodies resistance index changes， traditional Chinese medicine （TCM） syndrome integral changes， and changes in serum cytokine indexes， blood rheology indexes， and T lymphocyte subsets indexes were observed. SLE changes in disease activity index （SLEDAI-2000）， quality of life （SF-36） scores， and adverse reactions were explored. ResultThe total effective rate was 96.08% （49/51） in the observation group， higher than 84.31% （43/51） in the control group （χ²=3.991， P<0.05）. The onset time， symptom improvement time， skin lesion regression time， and hospital stays in the observation group were shorter than those in the control group （P<0.05，P<0.01）. Before treatment， erythrocyte sedimentation rate （ESR）， platelet count （PLT）， hemoglobin （HGB）， white blood cell count （WBC）， and other blood routine indexes， 24h urinary protein levels， anti-ds-DNA， TCM syndrome integral core， serum cytokine indexes including interleukin-4 （IL-4）， IL-6， soluble interleukin-2 receptor （sIL-2R）， blood rheology indexes （fibrinogen， plasma viscosity， and whole blood viscosity），T lymphocyte subsets indexes （CD4⁺， CD8⁺， and CD4⁺/CD8⁺）， SLEDAI-2000， and SF-36 score comparison in both groups had no statistical significance. After treatment， the above indicators were improved in each group （P<0.05）， and the indicators in the observation group was better than that in the control group （P<0.05）. In terms of the adverse reactions， there was 1 case of digestive tract reaction， 1 case of elevated aminotransferase， and 1 case of insomnia in the observation group. There were 2 cases of digestive tract reaction，1 case of infection， and 1 case of elevated transaminase in the control group. The difference of the adverse reactions between the two groups had no statistical significance. ConclusionXijiao Dihuangtang combined with acupuncture has good clinical effect on the treatment of SLE with syndrome of intense heat toxin， and the method is safe， reliable， and worthy of application.

Objective: To analyze the clinical risk factors of bronchopulmonary dysplasia(BPD) in very premature infants and provide reference for the prevention and treatment of BPD in order to improve the prognosis of premature infants. Methods: From January 2015 to December 2017, 263 very premature infants(referring to premature infants with gestational age between 28 weeks and 32 weeks) in the neonatology department of the Maternal and Child Health Care Hospital Affiliated to Anhui Medical University were selected.They were divided into BPD group(108 cases) and non-BPD group(155 cases) according to the diagnostic criteria of BPD.The clinical data of the patients and the hospitalized patients were retrospectively investigated.The general conditions of the very premature infants in the two groups were compared.The clinical risk factors for BPD in very premature infants were analyzed. Results: There were 263 very preterm infants included in the study, 108 cases in the BPD group, the incidence was 41.1%.The data analysis showed that BPD occurred in premature infants with sex(χ²=4.311), gestational age(Z=-6.544), birth weight(t=-5.382), maternal chorioamnionitis(χ²=4.946), neonatal respiratory distress syndrome(χ²=25.424), anemia(χ²=22.443), multiple blood transfusion(Z=-8.101), mechanical ventilation time greater than 7 days(χ²=10.946), high oxygen concentration(χ²=25.028), the differences were statistically significant(all P<0.05). The multivariate logistic regression analysis suggested that gestational age(OR=1.478, 95% CI: 1.140-1.914), maternal pregnancy with chorioamnionitis (OR=0.152, 95% CI: 0.029-0.797), maximum oxygen concentration>40%(OR=0.261, 95% CI: 0.136-0.502), number of blood transfusions(OR=0.582, 95% CI: 0.456-0.742) were independent risk factors for BPD in preterm infants. Conclusion There are many factors leading to BPD in premature infants, including maternal comorbidities and neonatal factors, and its pathogenesis is complex and diverse.It is necessary to further study these related factors, timely intervention, strengthen maternal health care, and minimize risk factors, thus to reduce the incidence of BPD, improve the prognosis of premature infants.

Objective Fructus Amomi(Sharen) is derived from the dry ripe fruit of Amomum villosum Lour., A.villosum Lour. var. xanthioides T.L. Wu et Senjen and A.longiligulate T.L.Wu, which is widely utilized for its clinic effects on digestive system. However, Fructus Amomi from different species and habitats, possessing different quality, is difficult to identify. In this study, we aim to develop a simple, rapid and reliable method for authentication of Fructus Amomi. Methods Twenty-five batches of samples of Fructus Amomi were collected and electronic nose was introduced into analyzing their odor with multiple mathematical statistics methods. Na?ve bayes network (NBN), radical basis function (RBF) and random forest (RF) were applied to establish different classifiers while BestFirst+CfsSubsetEval (BC) was used to screen the attributes for searching sensor array with higher contributions. Results Firstly, after attribute-screening via BC, the established discriminative models via NBN, RBF and RF could successfully identify genuine and non-genuine samples, presenting correct judging ratios of 78% and 84% through ten-fold cross validation and external test set validation, respectively. Besides, quantity predictive models were constructed as well. In case of content of bornyl acetate, one of the effective components in Fructus Amomi, values were higher than 3.5 mg/g and lower than 1.8 mg/g with sensor response of 0.04 and 0.03, respectively. Conclusion In this paper, quality discriminative model and quantity predictive model of Fructus Amomi were established via electronic nose and multiple mathematical statistics methods. It indicates that electronic nose could be a promising method for quality evaluation of Chinese material medica.

This study was aimed to identify Chrysanthemi Flosbefore and after sulfur fumigation based on its different odour by the electronic nose technology.It was expected to explore a new method for the Chrysanthemi Flos identification according to the odour.The electronic nose technology was used in the detection of peak response values of Chrysanthemi Flos on sensor array.The principal component analysis (PCA) and 10 machine learning (ML) ways were used in the analysis of response values and establishment of optimized identification models.The results showed that there was a significant difference in the odour between sulfur fumigated Chrysanthemi Flos and non-sulfur fumigated ones.The identification models were successful with high correct judge rate by PCA and 6 ML ways including BF Tree,J48 and Random Tree.It was concluded that the electronic nose technology can be used for the accurate identification of sulfur fumigated Chrysanthemi Flos and non-sulfur fumigated ones.The electronic nose technology combined with multiple ML methods can be introduced in the quality evaluation of Chrysanthemi Flos.It provided more ideas for the application of electronic nose in data mining for traditional Chinese medicine (TCM) studies.

This study was aimed to establish the TLC identification method of Radix Mirab ilis himalaic a. The β-sitosterol and daucosterol were used as the reference substances. The single-factor test was used. A variety of factors which affected TLC were systematically investigated to filter out the best TLC conditions for identification of different batches of medicines. The results showed that the best TLC conditions were as follows: silica gel G plates, extraction solvent (methanol), reagent (5% sulfuric acid in ethanol), extraction method (ultrasonic extraction with methanol), ex-tracted time (30 min), the agent (petroleum ether-ethyl acetate-acetone (5:2:1)) and sample volume (6 μL). It was concluded that the method, which had high separation degree, was reproducible and simple. It can be used as the quality control of Radix Mirab ilis himalaic a.
