Aim To explore the mechanism by which total coumarins in Pileostegia tomentella (TCPT) inhibits the proliferation of small cell lung cancer (SCLC) H1688 cells via inducing ferroptosis. Methods The gradient concentrations of TCPT were used to treat H1688 cells. CCK-8 assay was applied for detection of proliferative inhibition of H1688 cells. Transmission electron microscopy was used to approach the morphological changes of H1688 cells under the treatment of TCPT. Additionally, dichlorofluorescein (DCFH-DA) probe was used to detect the intracellular reactive oxygen species (ROS) level. BODIPY 581/ 589 Cll probe was applied to examine the intracellular lipid peroxide formation. Western blotting was employed to detect the expression levels of glutathione peroxidase 4 (GPX4), kelch-like ECH-associated protein (KEAP1), nuclear factor E2 related factor 2 (NRF2), ferritin heavy chain 1 (FTH1) proteins in HI688 cells. Results The proliferation of small cell lung cancer cell H1688 was dramatically inhibited after TCPT intervention (P < 0. 05, P < 0. 01). The morphological characteristics of ferroptosis induced by TCPT were observed by transmission electron microscope. TCPT could also effectively elevate intracellular level of ROS and lipid peroxide. In HI688 cells the expression of ferroptosis markers GPX4, NRF2, and FTH1 was down-regulated, while the expression of KEAP1 was up-regulated, and there were statistically significant differences among the markers mentioned a-bove (P<0. 01). Conclusions Total coumarins in TCPT can significantly inhibit the proliferation of H1688 cells, possibly through increasing ROS and intracellular lipid peroxide levels and eventually inducing ferroptosis.

Aim To explore the effects of ethanol extraction of Dysosma versipellis on the proliferation and apoptosis of renal clear cell carcinoma OS-RC-2 cells and the underlying mechanism. Methods After treated with Dysosma versipellis, the proliferation of OS-RC-2 cells was detected by the CCK-8 assay and clone formation assay. The migration rate of cells was detected by thewound healing assay and Transwell assay. The level of ROS was detected by the reactive oxygen detection kit. The common targets between Dysosma versipellis and ROS were obtained by the network pharmacology. The above common targets were analyzed by KEGG. The apoptosis rate and cell cycle were detected by the flow cytometry, and the key proteins of MAPK signaling pathway and the levels of apoptosis related proteins were measured by Western blot. Results The results showed that Dysosma versipellis significantly inhibited the cell viability and migration ability of 0S-RC-2 cells, and up-regulated the level of ROS. Network pharmacology analysis showed a total of 165 common targets between Dysosma versipellis and ROS. KEGG analysis of the common targets revealed that there were significant changes in the MAPK signaling pathway. The results of Western blot showed that after treated with Dysosma versipellis, the protein level of JNK and the ratio of p-ERK/ERK were down-regulated. Besides, the protein level of caspase-9 and Bcl-2 declined, while the levels of cleaved caspase-9 and Bax were promoted. The flow cytometry results showed that Dysosma versipellis could significantly promote the apoptosis rate,down-regulate the cells in Gl-phase,while up-regulate the cells in G2/M-phase. The results of the rescue experiment showed that co-administration of NAC and Dysosma versipellis could significantly reverse the cell viability and apoptosis rate, the level of apop-totic related proteins, as well as the protein levels of MAPK pathway,when compared to treated with Dysosma versipellis alone in OS-RC-2. Conclusion In summary, Dysosma versipellis may inhibit the MAPK signaling pathway via the changes in ROS,further promoting apoptosis rate and decline cell proliferation in OS-RC-2 cell line.

Objective: To evaluate the efficacy and safety of Nocardia rubra cell wall skeleton (Nr-CWS) in the treatment of persistent cervical high-risk human papillomavirus (HR-HPV) infection. Methods: A randomized, double blind, multi-center trial was conducted. A total of 688 patients with clinically and pathologically confirmed HR-HPV infection of the cervix diagnosed in 13 hispital nationwide were recruited and divided into: (1) patients with simple HR-HPV infection lasting for 12 months or more; (2) patients with cervical intraepithelial neoplasia (CIN) Ⅰ and HR-HPV infection lasting for 12 months or more; (3) patients with the same HR-HPV subtype with no CINⅡ and more lesions after treatment with CINⅡ or CIN Ⅲ (CINⅡ/CIN Ⅲ). All participants were randomly divided into the test group and the control group at a ratio of 2∶1. The test group was locally treated with Nr-CWS freeze-dried powder and the control group was treated with freeze-dried powder without Nr-CWS. The efficacy and negative conversion rate of various subtypes of HR-HPV were evaluated at 1, 4, 8, and 12 months after treatment. The safety indicators of initial diagnosis and treatment were observed. Results: (1) This study included 555 patients with HR-HPV infection in the cervix (included 368 in the test group and 187 in the control group), with an age of (44.1±10.0) years. The baseline characteristics of the two groups of subjects, including age, proportion of Han people, weight, composition of HR-HPV subtypes, and proportion of each subgroup, were compared with no statistically significant differences (all P>0.05). (2) After 12 months of treatment, the effective rates of the test group and the control group were 91.0% (335/368) and 44.9% (84/187), respectively. The difference between the two groups was statistically significant (χ2=142.520, P<0.001). After 12 months of treatment, the negative conversion rates of HPV 16, 18, 52, and 58 infection in the test group were 79.2% (84/106), 73.3% (22/30), 83.1% (54/65), and 77.4% (48/62), respectively. The control group were 21.6% (11/51), 1/9, 35.1% (13/37), and 20.0% (8/40), respectively. The differences between the two groups were statistically significant (all P<0.001). (3) There were no statistically significant differences in vital signs (body weight, body temperature, respiration, pulse rate, systolic blood pressure, diastolic blood pressure, etc.) and laboratory routine indicators (blood cell analysis, urine routine examination) between the test group and the control group before treatment and at 1, 4, 8, and 12 months after treatment (all P>0.05); there was no statistically significant difference in the incidence of adverse reactions related to the investigational drug between the two groups of subjects [8.7% (32/368) vs 8.0% (15/187), respectively; χ2=0.073, P=0.787]. Conclusion: External use of Nr-CWS has good efficacy and safety in the treatment of high-risk HPV persistent infection in the cervix.

This study explored the effects of Buyang Huanwu Decoction(BYHWD) on platelet activation and differential gene expression after acute myocardial infarction(AMI). SD rats were randomly divided into a sham-operated group, a model group, a positive drug(aspirin) group, and a BYHWD group. Pre-treatment was conducted for 14 days with a daily oral dose of 1.6 g·kg~(-1) BYHWD and 0.1 g·kg~(-1) aspirin. The AMI model was established using the high ligation of the left anterior descending coronary artery method. The detection indicators included myocardial infarct size, heart function, myocardial tissue pathology, peripheral blood flow perfusion, platelet aggregation rate, platelet membrane glycoprotein CD62p expression, platelet transcriptomics, and differential gene expression. The results showed that compared with the sham-operated group, the model group showed reduced ejection fraction and cardiac output, decreased peripheral blood flow, and increased platelet aggregation rate and CD62p expression, and activated platelets. At the same time, TXB_2 content increased and 6-keto-PGF1α content decreased in serum. Compared with the model group, BYHWD increased ejection fraction and cardiac output, improved blood circulation in the foot and tail regions and cardiomyocytes arrangement, reduced myocardial infarct size and inflammatory infiltration, down-regulated platelet aggregation rate and CD62p expression, reduced serum TXB_2 content, and increased 6-keto-PGF1α content. Platelet transcriptome sequencing results revealed that BYHWD regulated mTOR-autophagy pathway-related genes in platelets. The differential gene expression levels were detected using real-time quantitative PCR. BYHWD up-regulated mTOR, down-regulated autophagy-related FUNDC1 and PINK genes, and up-regulated p62 gene expression. The results demonstrated that BYHWD could regulate platelet activation, improve blood circulation, and protect ischemic myocardium in AMI rats, and its mechanism is related to the regulation of the mTOR-autophagy pathway in platelets.

Protective effect of Qilong Capsules(QL) on the myocardial fibrosis and blood circulation of rats with coronary heart disease of Qi deficiency and blood stasis type was investigated. Sleep deprivation and coronary artery ligation were used to construct a disease-symptom combination model, and 60 SD rats were divided into sham operation(sham) group, syndrome(S) group, disease and syndrome(M) group and QL group randomly. The treatment group received administration of QL 0.4 g·kg~(-1)·d~(-1). Other groups were given the same amount of normal saline. The disease indexes of each group [left ventricular end diastolic diameter(LVESD), left ventricular end systolic diameter(LVEDD), left ventricular ejection fraction(LVEF), left ventricular axis shortening rate(LVFS), myocardial histopathology, platelet morphology, peripheral blood flow] and syndrome indexes(tongue color, pulse, grip power) were detected. In sham group, cardiomyocytes and myocardial fibers were arranged neatly and densely with clear structures. The tongues' color in sham were light red, and the pulse shape were regular. RGB is a parameter reflected the brightness of the image of the tongue. In the S group, the amplitude and frequency of the animal's pulse increased accompanied by decreasing R,G,B, however, the decreased R,G,B was accompanied by reduced pulse amplitude in M group. And in M group, we observed fuzzy cell morphology, hypertrophied myocytes, disordered arrangement of cardiomyocytes and myocardial fibers, reduced peripheral blood flow and increased collagen volume fraction(CVF). Increased LVESD and LVEDD, and decreased LVEF and LVFS represented cardiac function in S group was significantly lower than that in sham. In QL group, the tongue's color was red and the pulse was smooth. The myocardial fibers of the QL group were arranged neatly and secreted less collagen. It improved the blood circulation in the sole and tail, and reversed the increasing of LVEDD, LVESD and the decreasing of LVEF and LVFS of M group. Platelets in M and S group showed high reactivity, and QL could decrease aggregation risk. In conclusion, Qilong Capsules has an obvious myocardial protective effect on ischemic cardiomyopathy, which may inhibit the degree of myocardial fibrosis and reduce platelet reactivity.

This study aims to explore the effect of Jinzhen Oral Liquid(JOL) on cough after infection in rats and the mechanism. To be specific, a total of 60 male SD rats were classified into 6 groups: normal group(equivalent volume of distilled water, ig), model group(equivalent volume of distilled water, ig), Dextromethorphan Hydrobromide Oral Solution group(3.67 mL·kg~(-1), ig), high-, medium-, and low-dose JOL groups(11.34, 5.67, and 2.84 mL·kg~(-1), respectively, ig). Lipopolysaccharide(LPS, nasal drip), smoking, and capsaicin(nebulization) were employed to induce cough after infection in rats except the normal group. Administration began on the 19 th day and lasted 7 days. Capsaicin(nebulization) was used to stimulate cough 1 h after the last administration and the cough frequency and cough incubation period in rats were recorded. The pathological morphology of lung tissue was observed based on hematoxylin-eosin(HE) staining. Immunohistochemistry(IHC) was used to detect the specific expression of transient receptor potential vanilloid 1(Trpv1), nerve growth factor(NGF), tropomyosin receptor kinase A(TrkA), and phosphorylated-p38 mitogen-activated protein kinase(p-p38 MAPK) in lung tissue, Western blot the protein expression of Trpv1, NGF, TrkA, and p-p38 MAPK in lung tissue, and real-time fluorescent quantitative polymerase chain reaction(real-time PCR) the mRNA expression of Trpv1, NGF, and TrkA. The results showed that model group demonstrated significantly high cough frequency, obvious proliferation and inflammatory cell infiltration in lung tissue, significantly enhanced positive protein expression of Trpv1, NGF, TrkA, and p-p38 MAPK in lung tissue and significant increase in the mRNA expression of Trpv1, NGF, and TrkA compared with the normal group. Compared with the model group, JOL can significantly reduce the cough frequency, alleviate the pathological changes of lung tissue, and decrease the protein expression of Trpv1, NGF, TrkA, and p-p38 MAPK in lung tissue, and high-dose and medium-dose JOL can significantly lower the mRNA expression of Trpv1, NGF, and TrkA. This study revealed that JOL can effectively inhibit Trpv1 pathway-related proteins and improve cough after infection. The mechanism is that it reduces the expression of NGF, TrkA, and p-p38 MAPK in lung tissue, thereby decreasing the expression of Trpv1 and cough sensitivity.

Objective: To understand the epidemiological characteristics of bacillary dysentery with multiple-onset in Henan province from 2005 to 2020. Methods: The reported cases of bacillary dysentery (including confirmed cases and clinically diagnosed cases) in Henan Province from January 2005 to December 2020 were collected through China's National Disease Supervision Information Management System. The main information included gender, age, home address, date of onset and date of diagnosis. The interval between two episodes of the same case was more than 15 days, which was judged as two episodes. The incidence characteristics of bacillary dysentery patients with two or more cases in Henan Province from 2005 to 2020 were analyzed, and the regional distribution map of cases was drawn using ArcGIS software. Results: From 2005 to 2020, a total of 250 430 cases of bacillary dysentery were reported in Henan Province, with a cumulative incidence rate of 228.66/100 000. There were 2 342 cases with two or more attacks. The incidence of recurrent cases of bacillary dysentery increased year by year (χ2trend=2 932.28, P<0.001). There was no significant difference in the incidence of two or more cases of different sexes (χ2=0.39, P=0.540). There was significant difference in the incidence among different age groups (χ2=438.40, P<0.001). The incidence of two or more cases in the 60-69 age group was relatively high (1.70%). The shortest time interval between the onset of the disease was 16 days, and the longest was 5 579 days, with M (Q1, Q3) about 428 (237, 843) days. Compared with healthy people, those with a history of bacterial diseases had a higher risk of developing bacillary dysentery (RR: 4.12, 95%CI: 3.95‒4.29). Conclusion: The proportion of patients with multiple-onset shows an increasing trend, and there is an age difference.
