Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

OBJECTIVE To study the antifungal activity of Huangqin decoction （HQD） against Trichophyton mentagrophytes and explore its mechanism. METHODS Minimal inhibitory concentration （MIC）， minimal fungicidal concentration （MFC）， mycelial length， spore germination rate， biomass and mycelium ultrastructure observation were performed to evaluate the antifungal activity of HQD against T. mentagrophytes. The effects of HQD on the cell wall of T. mentagrophytes were detected through sorbitol protection experiment. By measuring the content of ergosterol and the activities of squalene epoxide （SE） and lanosterol 14α-demethylase （CYP51）， the activity of HQD on the cell membrane of T. mentagrophytes was investigated. The effects of HQD on T. mentagrophytes mitochondria were investigated by determining the activities of malate dehydrogenase （MDH）， succinate dehydrogenase （SDH）， and ATPases （including sodium potassium ATPase， calcium magnesium ATPase， and total ATPase）. RESULTS HQD exhibited significant antifungal activity against T. mentagrophytes with MIC of 3.13 mg/mL and MFC of 25 mg/mL. After intervention with HQD， the mycelial length of T. mentagrophytes was significantly shortened （P＜0.05）； spore germination rate， biomass， the content of ergosterol in the cell membrane， the activities of SE and CYP51 in the cell membrane and MDH， SDH and ATPase in mitochondria were all decreased significantly （P＜0.05）； cell structure had been ；damaged to a certain extent， but the integrity of the cell wall had not been affected. CONCLUSIONS HQD shows significant antifungal activity against T. mentagrophytes， the mechanism of which may be associated with reducing the 0791- content of ergosterol in the cell membrane and the activities of SE， CYP51， and mitochondria-related enzymes.

Objective To analyze the status of influenza A and B virus infection in patients admitted to Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong University School of Medicine from 2022 to 2023,and to provide scientific basis for the adjustment of influenza prevention and control measures in this area.Methods The positive status of influenza A and B virus antigen and nucleic acid were analyzed to deter-mine the prevalence and dominant types of influenza in 2022-2023.The peak of influenza A virus infection in 2023 was analyzed by antigen detection and nucleic acid detection,and the positive rates of influenza A virus detection in patients with different genders and ages were compared.Results In 2022 and 2023,the majority of patients were infected with influenza A virus.There was no significant difference in the positive rate of in-fluenza A virus antigen and nucleic acid detection between male and female patients(P＞0.05).The positive rates of influenza A virus antigen and nucleic acid detection in patients of different ages were statistically sig-nificant(P＜0.05).Compared with other age range,the positive rate of influenza A virus antigen and nucleic acid detection was the highest in patients＞5-10 years old.From February to December 2023,the positive rate of influenza A virus nucleic acid detection(50.91％)was significantly higher than that of influenza A vi-rus antigen detection(28.73％),and the difference was statistically significant(P＜0.05).Conclusion There is no influenza virus infection peak in 2022,and there are two influenza A virus infection peaks in 2023.The positive rates of influenza A virus antigen and nucleic acid detection are different due to different detection methods.

OBJECTIVE To establish the fingerprint of Huangqin decoction （HQD）， to separate the phase states and screen the active phase states of antidermatophytic activity so as to study the spectrum-effect relationship. METHODS HPLC method was adopted using baicalin as reference， the fingerprints of 10 batches of HQD were drawn and the similarity evaluation was carried out using the Similarity Evaluation System of Chromatographic Fingerprint of TCM （2012 edition） to determine the common peak； the phase states of HQD were separated and characterized by high-speed centrifugation and membrane dialysis. The minimum inhibitory concentrations （MIC） of HQD and its different phase states against Trichophyton mentagrophytes were determined simultaneously. Using the peak area of 37 common peaks as independent variable， MIC as dependent variable， Pearson correlation analysis was performed by using SPSS 21.0 software. RESULTS A total of 37 common peaks were obtained in HPLC fingerprints of 10 batches of HQD， with the similarity higher than 0.99. Ten components were identified， such as albiflorin， paeoniflorin， liquiritin apioside， baicalin， melaleuca glycoside A， wogonoside， baicalein， glycyrrhizic acid， wogonin and oroxylin A. HQD was split into 3 phase states， such as precipitation phase （HQD-P）， solution phase （HQD-S） and nano phase （HQD-N）. The morphology of HQD-P was irregular granular， and the average particle size was 4.670-91.522 μm. The morphology of HQD-S was uniform flakes， and no particle size was detected. HQD-N was spherical in shape and the particle size was （129.0±12.9） nm. MIC values of each phase state of HQD against T. mentagrophytes in different phase states were HQD-N （4.64 mg/mL） ＜HQD （5.85 mg/mL） ＜HQD-P （7.37 mg/mL） ＜HQD-S （12.89 mg/mL） at the same dosage. Pearson correlation analysis showed that the peak area of 25 of the 37 common peaks （including identified components） was significantly negatively correlated with MIC （absolute values of correlation coefficient＞0.95 and P＜0.05）. CONCLUSIONS The chemical composition of 10 batches of HQD is consistent； HQD-N is the active phase state of HQD. Ten components such as paeoniflorin， liquiritin apioside and baicalin may be the main active components of HQD. The antidermatophytic effect of HQD is closely related to its component content and physical phase state.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective To investigate the effect of 6-paradol on the proliferation, migration, and invasion of human intrahepatic cholangiocarcinoma cells and its mechanism. Methods Human intrahepatic cholangiocarcinoma cell lines HCCC 9810 and HUCCT1 were treated with different concentrations of 6-paradol or an equal volume of DMSO (control group), and then CCK-8 assay, plate colony formation assay, wound healing assay, and Transwell assay were used to measure cell proliferation, migration, and invasion. The bioinformatics software Swiss Target Prediction was used to predict the protein targets of 6-paradol, and Western blot was used to measure the protein expression levels of STAT3, p-STAT3, SRC, p-mTOR, p21, Bcl-2, and p53; Drug Affinity Responsive Target Stability (DARTS) assay was used to investigate the interaction between 6-paradol and STAT3. After cholangiocarcinoma HCCC 9810 and HUCCT1 cells were transfected with STAT3 overexpression plasmid or sh-p21 plasmid, quantitative real-time PCR was used to measure the mRNA expression levels of STAT3 and p21, and Western blot was used to measure the protein expression levels of STAT3 and p21; CCK-8 assay, wound healing assay, and Transwell assay were used to measure cell proliferation, migration, and invasion. The t -test was used for comparison of data between two groups; an analysis of variance was used for comparison between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the control group, the 6-paradol treatment groups had significant reductions in cell proliferation, migration, and invasion ( P < 0.05). Compared with the control group, the 6-paradol treatment groups had significant reductions in the expression levels of STAT3 and p-STAT3 (all P < 0.05) and a significant increase in the expression level of p21 (all P < 0.05), while there were no significant changes in the expression levels of Bcl-2, SRC, and p-mTOR (all P > 0.05). In the 6-paradol treatment groups, the proportion of STAT3 hydrolyzed by protease was reduced by 48.66% and 45.33%, respectively ( t =16.64 and 8.76, both P < 0.05); after transfection with STAT3 overexpression plasmid or p21-silencing plasmid in cholangiocarcinoma cells, there was a significant increase in the mRNA expression level of STAT3 ( t HCCC 9810 =2.82, t HUCCT1 =5.60, both P < 0.05) and a significant reduction in the mRNA expression level of p21 ( t HCCC 9810 =6.84, t HUCCT1 =3.91, both P < 0.05). CCK-8 assay showed that for HCCC 9810 and HUCCT1 cells treated with 6-paradol for 48 and 72 hours, the STAT3 overexpression group had a significantly higher proliferation rate than the single administration group, and the p21 silencing group also had a significantly higher proliferation rate than the single administration group ( P < 0.05). The wound healing assay showed that the HCCC 9810 and HUCCT1 cells with STAT3 overexpression or p21 silencing had a significantly higher wound healing rate than the single administration group (all P < 0.05). Transwell assay showed that the HCCC 9810 and HUCCT1 cells with STAT3 overexpression or p21 silencing had significant increases in migration rate and invasion rate compared with the single administration group (all P < 0.05). Conclusion 6-Paradol inhibits the proliferation, migration, and invasion of cholangiocarcinoma cells by targeting the STAT3-p21 pathway.

OBJECTIVE To study the effects of self-assembled nanoparticles from Shaoy ao gancao decoction （SGD-SAN）on the in vitro release and intestinal absorption of the main components of Glycyrrhiza uralensis . METHODS Gancao single decoction （GSD），Shaoyao single decoction （SSD），mixed suspension of Shaoyao and Gancao single decoction （MSSGD）and SGD （i.e. Shaoyao-Gancao decoction ）were prepared ，and SAN was characterized. HPLC method was adopted to determine the contents of 7 main components （liquiritin apioside ， liquiritin， isoliquiritin apioside ， isoliquiritin， liquiritigenin， glycyrrhizic acid ， isoliquiritigenin）in G. uralensis . The dialysis bag method was used to investigate the effects of the formation of SGD-SAN on in vitro release of 7 main components in G. uralensis with pH 1.2 HCl solution and pH 6.8 phosphate buffered solution （PBS）as release media. Single-pass intestinal perfusion study was performed to investigate the effects of the formation of SGD-SAN on the intestinal absorption of 7 main components from G. uralensis . RESULTS SAN with particle size of 200-300 nm and polydispersity index of 0.3-0.5 was found in GSD ，MSSGD and SGD. GSD-SAN and MSSGD-SAN were in rod shape while SGD-SAN was irregularly spherical under transmission electron microscope. The results of in vitro release study showed that the formation of SGD-SAN could significantly increase in vitro release of liquiritigenin ，isoliquiritigenin and glycyrrhizic acid ，and had no effect on other components of G. uralensis in pH 1.2 HCl solution. The formation of SGD-SAN also had no effect on the release of each component from G. uralensis in pH 6.8 PBS. The results of intestinal perfusion experiments showed that the formation of SGD-SAN could significantly promote the absorption of each component from G. uralensis in the ileum. CONCLUSIONS- The formation of SGD-SAN significantly improves the in vitro release of poorly soluble components from G. uralensis and promotes the intestinal absorption of main components from G. uralensis ，which is the physical structure basis for the compatibility and synergy of Paeonia lactiflora and G. uralensis .

Objective:To explore the expression of circular RNA circ-MYBL2 in prostate cancer tissue and the molecular mechanism of its influence on the occurrence and metastasis of prostate cancer.Methods:From February 2017 to April 2021, 45 cases of prostate cancer tissues and paracancerous tissues from patients with prostate cancer in the Department of Urology, Jingmen No.2 People′s Hospital were selected. quantitative real-time fluorescence polymerase chain reaction (qRT-PCR) was used to detect the difference in expression of circ-MYBL2 in prostate cancer tissues and adjacent tissues, and the difference in expression of circ-MYBL2 in prostate cancer cell lines and immortalized prostate duct epithelial cells. Cell lines with low circ-MYBL2 expression were respectively transfected with circ-MYBL2 plasmid (circ-MYBL2 group) or negative control plasmid (control group). qRT-PCR was used to detect the transfection efficiency of circ-MYBL2 plasmid. CCK-8 method and cell scratch test were used to detect the effect of circ-MYBL2 on cell proliferation and migration. The starBase v2.0 software was used to predict the miRNA bound by circ-MYBL2 and the target gene of miRNA. The dual luciferase reporter gene experiment was used to verify the regulatory relationship between circ-MYBL2 and miRNA. qRT-PCR was used to detect the influence of circ-MYBL2 on miRNA expression and the influence of miRNA on target gene mRNA expression. Western blotting was used to detect the expression of target gene protein and Wnt/β-catenin signaling pathway proteins. The measurement data were expressed as mean±standard deviation ( Mean± SD), the comparison between the means of multiple samples used one-way analysis of variance, and the comparison between the means of two samples used the t-test. Results:The expression of circ-MYBL2 of DU-145 cells in prostate cancer tissue was significantly lower than that in adjacent tissues ( P<0.01). The expression of circ-MYBL2 in prostate cancer cell lines was significantly lower than that of prostate ductal epithelial cells ( P<0.01), and the expression of DU-145 cells was the lowest ( P<0.01). Compared with the control group, the expression of circ-MYBL2 of DU-145 cells in the circ-MYBL2 group increased significantly ( P<0.01), and circ-MYBL2 reduced the proliferation activity ( P<0.05) and migration ability ( P<0.01) of DU-145 cells. circ-MYBL2 acted as a sponge to adsorb miR-324-3p, and miR-324-3p complementarily bound to the suppressor of SUFU gene. circ-MYBL2 inhibited the expression of miR-324-3p ( P<0.01), SUFU gene expression was increased ( P<0.01), and Wnt/β-catenin signal pathway transduction was inhibited. Conclusion:circ-MYBL2 promotes the expression of SUFU gene by adsorbing miR-324-3p, inhibits the Wnt/β-catenin signaling pathway, thereby reducing the proliferation activity and migration ability of prostate cancer cells.
