Characteristics of Traditional Chinese Medicine Syndromes and Treatments of COVID-19 Patients from Two Hospitals Based on “Treatment of Disease in Accordance with Three Conditions” / 中国实验方剂学杂志

ObjectiveTo explore the guidance value of “treatment of disease in accordance with three conditions” theory in the prevention and treatment of corona virus disease 2019（COVID-19） based on the differences of syndromes and traditional Chinese medicine（TCM） treatments in COVID-19 patients from Xingtai Hospital of Chinese Medicine of Hebei province and Ruili Hospital of Chinese Medicine and Dai Medicine of Yunnan province and discuss its significance in the prevention and treatment of the unexpected acute infectious diseases. MethodDemographics data and clinical characteristics of COVID-19 patients from the two hospitals were collected retrospectively and analyzed by SPSS 18.0. The information on formulas was obtained from the hospital information system （HIS） of the two hospitals and analyzed by the big data intelligent processing and knowledge service system of Guangdong Hospital of Chinese Medicine for frequency statistics and association rules analysis. Heat map-hierarchical clustering analysis was used to explore the correlation between clinical characteristics and formulas. ResultA total of 175 patients with COVID-19 were included in this study. The 70 patients in Xingtai，dominated by young and middle-aged males，had clinical symptoms of fever， abnormal sweating，and fatigue. The main pathogenesis is stagnant cold-dampness in the exterior and impaired yin by depressed heat， with manifest cold， dampness， and deficiency syndromes. The therapeutic methods highlight relieving exterior syndrome and resolving dampness， accompanied by draining depressed heat. The core Chinese medicines used are Poria，Armeniacae Semen Amarum，Gypsum Fibrosum，Citri Reticulatae Pericarpium，and Pogostemonis Herba. By contrast，the 105 patients in Ruili， dominated by young females， had atypical clinical symptoms， and most of them were asymptomatic patients or mild cases. The main pathogenesis is dampness obstructing the lung and the stomach， with obvious dampness and heat syndromes. The therapeutic methods are mainly invigorating the spleen， resolving dampness， and dispersing Qi with light drugs. The core Chinese medicines used are Poria，Atractylodis Macrocephalae Rhizoma，Glycyrrhizae Radix et Rhizoma，Coicis Semen，Platycodonis Radix，Lonicerae Japonicae Flos， and Pogostemonis Herba. ConclusionThe differences in clinical characteristics， TCM syndromes， and medication of COVID-19 patients from the two places may result from different regions，population characteristics， and the time point of the COVID-19 outbreak. The “treatment of disease in accordance with three conditions” theory can help to understand the internal correlation and guide the treatments.

Exploration of Potential Mechanisms of Corylin Against Lung Cancer By High-throughput Sequencing / 中国实验方剂学杂志

Objective:To explore the potential molecular mechanism of corylin in the treatment of lung cancer. Method:A549 cells were treated with different concentrations of corylin， and their proliferation was detected using methye thiazolye telrazlium （MTT） reagent. Then the trend analysis and gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were conducted to screen the key genes and pathways of corylin against A549 cell proliferation， followed by the verification of sequencing results by real-time polymerase chain reaction （Real-time PCR）. Result:Corylin inhibited the proliferation of A549 cells and regulated the expression of 4 364 genes in cells. The trend analysis revealed that these genes were clustered into 20 distinct modules， among which four were significantly down-regulated， suggesting that corylin exerted the anti-proliferation effect by inhibiting the expression of some genes. The inter-group comparison of differentially expressed genes （DEGs） showed that the elevation in the concentration of corylin resulted in more down-regulated genes but weakened proliferation， consistent with the findings by trend analysis. The GO and KEGG enrichment analysis of 278 DEGs in the high-dose corylin group demonstrated that corylin mainly changed the cellular and metabolic processes， which was attributed to its regulation of steroid biosynthesis， fatty acid metabolism， biosynthesis of unsaturated fatty acids， synthesis and degradation of ketone bodies， and steroid hormone biosynthesis. The Real-time PCR results confirmed that corylin down-regulated the mRNA expression levels of LSS， stearoyl-CoA desaturase （SCD）， 3-hydroxy-3-methylglutaryl-CoA synthase 1 （HMGCS1）， but up-regulated the mRNA expression of recombinant human angiopoietin-like protein 4 （ANGPTL4）， basically consistent with the transcriptomics results. Conclusion:Corylin inhibits A549 cell proliferation and alleviates lung cancer by targeting the related genes in lipid metabolism pathways.

Recognition of Similarities and Differences--a New Thinking Paradigm of Critically Care Integrative Medicine / 中国中西医结合杂志

"Wise men could recognize similarities, but the fool only recognizes differences" in Su-wen, which expounded clinical thinking methods of Chinese medicine (CM). "To recognize similarities and differences simultaneously" is of important clinical significance in understanding the laws of diseases. CM pays much attention to recognize similarities, while modern medicine emphasizes the differences observed. In order to develop integrative medicine (IM), similarities recognition and differences identification must be combined together to innovate new thinking methods of IM.

Correlation between typing of peripheral neuroblastic tumors and prognosis: a clinicopathologic study of 135 cases / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the clinicopathologic characteristics of peripheral neuroblastic tumors and to investigate the prognostic significance of International Neuroblastoma Pathology Classification (INPC).</p><p><b>METHODS</b>One hundred and thirty-five cases of peripheral neuroblastic tumors encountered in Shanghai Children's Medical Center were enrolled into the study. All the cases were classified according to INPC and International Neuroblastoma Staging System (INSS). The follow-up data were analyzed.</p><p><b>RESULTS</b>The consensus diagnoses of the 135 cases were as follows: 80 cases (59.2%) of neuroblastoma, 24 cases (17.8%) of ganglioneuroblastoma, intermixed, 17 cases (12.6%) of ganglioneuroma and 14 cases (10.4%) of ganglioneuroblastoma, nodular. The cases were subdivided into 2 subgroups: favorable histology (number = 90, 66.7%) and unfavorable histology (number = 45, 33.3%). According to INSS, the number of cases in stages I, II, III and IV was 22 (16.3%), 24 (17.8%), 34 (25.2%) and 55 (40.7%), respectively. The survival of peripheral neuroblastic tumors correlated with histologic diagnosis, INPC and INSS (P < 0.05).</p><p><b>CONCLUSION</b>Diagnostic categorization of peripheral neuroblastic tumors according to INPC is of prognostic value.</p>

Unusual expression and molecular mechanisms of E-cadherin, beta-catenin in correlation with clinicopathologic parameters in neuroblastoma / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the expression of E-cadherin and beta-catenin in neuroblastomas of various degrees of differentiation, and to investigate their molecular mechanisms in correlation with clinicopathologic parameters.</p><p><b>METHODS</b>Immunohistochemistry EnVision method was used to detect E-cadherin and beta-catenin expression in 90 paraffin-embedded tissue samples of neuroblastomas. The methylation status of CpG islands of E-cadherin promoter was investigated by MSP in 7 fresh tissue and 24 paraffin-embedded tissue samples. The mutation status of exon 3 of beta-catenin gene was studied by PCR in 7 fresh tissue samples. Statistical analysis of the data was performed by SPSS software.</p><p><b>RESULTS</b>E-cadherin and beta-catenin were abnormally expressed in neuroblastomas in general. The expression of beta-catenin in well-differentiated neuroblastoms was markedly higher (47/70, 67.1%) than that of the poorly differentiated tumors (8/20, 40.0%). There was a markedly decreased expression of both genes in tumors with lymph node metastasis than those without. Demethylation was seen in some regions of the promoter of E-cadherin in 31 cases of nuroblatomas. PCR of the exon 3 of beta-catenin followed by DNA sequencing demonstrated rearrangements and mutations in 7 cases, including 2 cases harboring identical point mutation at gene position 27184, leading to a T-->A alteration.</p><p><b>CONCLUSIONS</b>The abnormal over-expression of E-cadherin in neuroblastomas is independent of the methylation status of their promoter sequences. The abnormal expression of beta-catenin may be related to mutational changes at exon 3 of the gene.</p>
