Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

ObjectiveTo investigate the expression level of HBV cccDNA in patients in the convalescence stage of hepatitis B virus-related acute-on-chronic liver failure （HBV-ACLF） and its correlation with HBV markers and liver histopathological changes. MethodsA total of 30 patients in the convalescence stage of HBV-ACL who were hospitalized in The Ninth Hospital of Nanchang from January 2015 to October 2023 were enrolled as liver failure group， and 9 patients with chronic hepatitis B （CHB）， matched for sex and age， were enrolled as control group. The content of HBV cccDNA in liver tissue was measured， and its correlation with clinical data and laboratory markers was analyzed. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and a one-way analysis of variance or the Kruskal-Wallis H test was used for comparison between multiple groups； the Fisher’s exact test was used for comparison of categorical data between groups. A Spearman correlation analysis was performed. ResultsThe liver failure group had a significantly lower content of HBV cccDNA in liver tissue than the control group （-0.92±0.70 log₁₀ copies/cell vs -0.13±0.91 log₁₀ copies/cell， t=2.761， P=0.009）. In the liver failure group， there was no significant difference in the content of HBV cccDNA in liver tissue between the HBeAg-positive patients and the HBeAg-negative patients （P>0.05）； there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with different grades （G0-G2， G3， and G4） of liver inflammatory activity （P>0.05）； there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with different stages （S0-S2， S3， and S4） of liver fibrosis （P>0.05）； there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with negative HBV DNA and those with positive HBV DNA （P>0.05）. For the liver failure group， the content of HBV cccDNA in liver tissue was positively correlated with the content of HBV DNA in liver tissue （r=0.426， P=0.043） and was not significantly correlated with the content of HBV DNA in serum （P>0.05）. ConclusionThere is a significant reduction in the content of HBV cccDNA in liver tissue in the convalescence stage of HBV-ACLF. HBV cccDNA exists continuously and stably in liver tissue and can better reflect the persistent infection and replication of HBV than HBV DNA in serum and liver tissue.

Objective To analyze the differences in the epidemiological characteristics,susceptible popula-tions,and laboratory index of patients with common acute upper respiratory tract infections(novel coronavir-us infection,influenza A and influenza B)between plateau and plain areas.Methods Clinical data of 408 008 patients with symptoms of fever or upper respiratory tract infection in the fever clinic of the Second Affiliated Hospital of Zhejiang University and General Hospital of Xizang Military Command from January 2023 to Au-gust 2024 were collected.The epidemic characteristics,susceptible populations,and peripheral blood test data were compared and analyzed.Results The total positive rate of novel coronavirus infection,influenza A virus and influenza B virus infection in plain group(17.86％)was higher than that in plateau group(14.49％),and the difference was statistically significant(P＜0.05).The positive rates(17.98％and 17.76％)of male and female upper respiratory tract infection pathogens(novel coronavirus,influenza A virus and influenza B virus)in plain group were higher than those in plateau group(13.94％and 16.00％),and the differences were statis-tically significant(P＜0.05).The total positive rates of three kinds of upper respiratory tract infection patho-gens were 16.21％,18.27％and 14.63％in the plain group,and 14.62％,14.06％and 21.26％in the plateau group,respectively.According to the results of pathogen analysis of susceptible populations,whether it was plateau or plain,the positive rate of influenza A virus was higher in the minor group,the positive rate of influ-enza B virus was highest in the adult group,and the positive rate of novel coronavirus was highest in the elder-ly group.In terms of epidemic season,plateau and plain areas were different,and the epidemic occurred earlier in the plain area.In terms of peripheral blood test indicators,there were statistically significant differences in lymphocyte count,monocyte count,neutrophil to lymphocyte ratio and other indicators between plateau group and plain group(P＜0.05),while there were no statistically significant differences in white blood cell count between plateau group and plain group(P＞0.05).Conclusion The epidemiological characteristics of acute upper respiratory tract infection in plateau area are obviously different from those in plain area,which may be related to the natural environment and human geography environment.

Objective To explore the mechanism of the long non-coding RNA(lncRNA)small nucleolar RNA host gene 1(SNHG1)/microRNA(miR)-340-5p/pentraxin 3(PTX3)signaling pathway in osimertinib resistance of lung cancer.Methods The expression levels of SNHG1,miR-340-5p and PTX3 in lung cancer tissues,adjacent tissues and osimertinib-sensitive and resistant cell lines were detected by real-time fluores-cence quantitative PCR.SNHG1 was knockdown using siRNA to detect its effects on cell proliferation,apopto-sis and osimertinib sensitivity.The dual-luciferase reporter assay verified the binding relationship between SNHG1 and miR-340-5p,as well as between miR-340-5p and PTX3.Western blotting was used to analyze the expression changes of PTX3 protein.Results SNHG1 was highly expressed in lung cancer tissues and osimer-tinib-resistant cells,while the expression of miR-340-5p was downregulated.SNHG1 inhibits the function of miR-340-5p by directly binding to it and releases the negative regulation of miR-340-5p on PTX3,resulting in the high expression of PTX3 in lung cancer drug-resistant cells.Knockdown of SNHG1 can increase the apop-tosis rate of drug-resistant cells,inhibit the ability of colony formation,and enhance the sensitivity of cells to osimertinib.The miR-340-5p inhibitor upregulated the expression of PTX3 in lung cancer sensitive cells.Con-clusion SNHG1 as competitive endogenous RNA inhibition of miR-340-5p,thus raising PTX3 expression,the drug resistance of lung cancer cells,SNHG1/miR-340-5p/PTX3 shaft may provide potential targets in the treatment of lung cancer drug resistance.

Objective To construct a conditional knockout mice model of cysteine-rich angiogenesis inducer 61(Cyr61,also known as Ccn1)gene in myocardium and skeletal muscle regulated by CRE recombinant enzyme.Methods C57BL/6 mice were used to create CKmm-Cre+/-Cyr61flox/flox mice by using CRISPR/Cas9 technology.The successful construction of conditional knockout mice was confirmed by identifying the Cyr61flox/flox,3'LoxP and Cre enzyme sequences in mice.The knockout efficiency of Cyr61 was confirmed by Western blot.The skeletal mus-cle function of Cyr61 knockout mice was evaluated and following related indicators in the myocardium and skeletal muscle were detected by Western blot:Aging(p53,p21),inflammatory response(TNF-α,IL-18,IL-1β),fibrosis(vimentin,TGF-β,α-SMA,COL1).Results The mice were successfully bred and identified.In comparison with the control group,Cyr61 protein level showed a significant decrease in both myocardium and skeletal muscle in the experimental group(P＜0.01).Compared with the control group,the experimental group mice showed increased skeletal muscle grip strength(P＜0.05),enhanced maximum single contraction force(P＜0.01),and increased average cross-sectional area of the anterior tibialis muscle(P＜0.05).The expression level of p21,TNF-α,IL-18,IL-1β,TGF-β,and COL1 proteins in the myocardium and skeletal muscle of the experimental group was all lower than those of the control group(P＜0.05).Conclusions Myocardial and skeletal muscle-specific Cyr61 gene condi-tional knockout mice were successfully constructed based on Cre-LoxP technology and heritable trait could be passed stably.
