ObjectiveTo explore the mechanism of Shenmai injection in improving cisplatin resistance in non-small cell lung cancer （NSCLC） based on the endoplasmic reticulum stress through protein kinase R-like endoplasmic reticulum kinase （PERK）/activated transcription factor 4 （ATF4）/C/EBP homologous protein （CHOP） signaling pathway. MethodsBALB/c nude mice bearing cisplatin-resistant human lung cancer cell line （A549/cisplatin） were randomly divided into four groups： Blank control group （0.9% sodium chloride）， cisplatin group （5 µg·g^-1cisplatin）， Shenmai injection group （5.2 mg·g^-1 Shenmai injection）， and combination therapy group （5.2 mg·g^-1 Shenmai injection +5 µg·g^-1cisplatin）. The drug intervention lasted for 4 weeks， and the changes in body weight and tumor volume were monitored. Hematoxylin-eosin （HE） staining was performed to observe tumor tissue pathology. Transmission electron microscopy （TEM） was used to assess the morphology of the endoplasmic reticulum. Immunohistochemical assay was conducted to measure the positive expressions of PERK， ATF4， and CHOP in tumor tissues. Western blot quantified the protein expression of immunoglobulin heavy chain binding protein （BIP）， PERK， phosphorylated PERK （p-PERK）， eukaryotic translation initiation factor 2α （eIF2α）， phosphorylated eIF2α （p-eIF2α）， ATF4， CHOP， B-cell lymphoma -2 （Bcl-2）， and Bcl-2 Associated X protein （Bax）. A549/cis cells were divided into blank group： Blank control group （normal culture medium）， cisplatin group （23.3 µmol·L^-1 cisplatin）， Shenmai Injection group （20 g·L^-1 Shenmai injection）， and combination therapy group （20 g·L^-1 Shenmai injection+23.3 µmol·L^-1 cisplatin）. Cell counting kit-8 （CCK-8） method was used to detect cell viability， TEM was used to observe the morphology of endoplasmic reticulum， and Western blot was used to detect endoplasmic reticulum stress and apoptosis-related proteins. ResultsCompared with the cisplatin group， the combination therapy group showed increased body weight （P<0.05）， decreased tumor volume （P<0.05）， and expanded endoplasmic reticulum in tumor cells. The positive expressions of PERK， ATF4， and CHOP increased （P<0.05）. Western blot revealed elevated protein expression levels of BIP， p-PERK/PERK， p-eIF2α/eIF2α， ATF4， CHOP， and Bax （P<0.05）， while Bcl-2 expression decreased （P<0.05）. As shown in the in vitro experiment， compared with the cisplatin group， the combination therapy group exhibited a reduced cell survival rate （P<0.05）. TEM revealed increased endoplasmic reticulum dilation and vesicular degeneration. Western blotting showed increased protein levels of BIP， p-PERK/PERK， p-eIF2α/eIF2α， ATF4， CHOP and Bax （P<0.05）， with decreased Bcl-2 expression （P<0.05）. ConclusionShenmai injection combined with cisplatin has a synergistic antitumor effect in NSCLC， which may be attributed to the activation of endoplasmic reticulum stress response mediated by the PERK/eIF2α/ATF4/CHOP signaling pathway and the induction of tumor cell apoptosis.

ObjectiveTo investigate the impact of Buzhong Yiqitang combined with cisplatin on the proliferation of human lung adenocarcinoma （A549） cells through regulation of the pyruvate dehydrogenase kinase 1 （PDK1）/protein kinase B （Akt） signaling pathway and influence on glycolysis. MethodsTranscriptome sequencing （RNA-seq） was employed to compare the expression of glycolysis-related genes between A549 cells and cisplatin-resistant human lung adenocarcinoma cells （A549/DDP）. Small interfering RNA （siRNA） was employed to knock down PDK1， and the knockdown efficiency was verified by Western blot and Read-time PCR. The cell counting kit-8 （CCK-8） assay was used to assess the survival and viability of A549 cells under the following conditions： siRNA negative control+cisplatin （128， 64， 32， 16， 8， 4， 0 μmol·L^-1）， siPDK1+cisplatin （128， 64， 32， 16， 8， 4， 0 μmol·L^-1）， and siPDK1+cisplatin （128， 64， 32， 16， 8， 4， 0 μmol·L^-1）+Buzhong Yiqitang （10%）-containing serum. The 20% inhibitory concentration （IC₂₀） of the siRNA negative control+cisplatin group （7.832 μmol·L^-1） was calculated and used as the subsequent cisplatin concentration. Colony formation assay was performed to evaluate the proliferation of A549 cells. Lactate and adenosine triphosphate （ATP） assay kits were used to measure lactate and ATP production. The mitochondrial membrane potential was detected with the fluorescent probe JC-1. Western blotting was conducted to examine the expression levels of PDK1， phosphorylated （p）-Akt， Akt， pyruvate kinase M2 （PKM2）， glucose transporter 1 （GLUT1）， pyruvate dehydrogenase （PDH）， and lactate dehydrogenase A （LDHA）. Confocal immunofluorescence was employed to detect PDK1 and p-Akt. ResultsRNA-seq results identified PDK1 as a highly expressed differential gene in glycolysis metabolism between A549 cells and A549/DDP cells， and it was highly expressed in tumor cells. Gene Set Enrichment Analysis （GSEA） revealed upregulated and downregulated genes in glycolysis and gluconeogenesis pathways. Western blot and RT-qPCR confirmed that PDK1-si-2 had the highest transfection efficiency， with a PDK1 knockdown rate exceeding 60%. CCK-8 assay determined the half-maximal inhibitory concentration （IC₅₀） values for each group as （30.698±5.348）， （16.372±3.562）， （13.237±1.573） μmol·L^-1， while the IC₂₀ of cisplatin in siRNA negative control-transfected A549 cells was （7.832±0.672） μmol·L^-1. Compared with the siRNA negative control group， the siRNA negative control+cisplatin group showed decreased colony formation rate， reduced lactate production， lowered mitochondrial membrane potential， downregulated protein levels of p-Akt， GLUT1， PDK1， PDH， and LDHA， and reduced PDK1 fluorescence intensity （P<0.05）. The siPDK1 group exhibited decreased colony formation rate， reduced lactate production， increased ATP production， lowered mitochondrial membrane potential， downregulated protein levels of p-Akt， PKM2， GLUT1， PDK1， PDH， and LDHA， and reduced PDK1 and p-Akt fluorescence intensity （P<0.05）. Compared with the siPDK1 group， the siPDK1+Buzhong Yiqitang group showed decreased colony formation rate， reduced lactate production， downregulated protein levels of PKM2， GLUT1， and PDK1， and reduced PDK1 fluorescence intensity （P<0.05）. The siPDK1+cisplatin group exhibited decreased colony formation rate， reduced lactate production， increased ATP production， lowered mitochondrial membrane potential， downregulated protein levels of PKM2， GLUT1， PDK1， and PDH， and reduced PDK1 and p-Akt fluorescence intensity （P<0.05）. The siPDK1+cisplatin+Buzhong Yiqitang group demonstrated decreased colony formation rate， reduced lactate production， increased ATP production， lowered mitochondrial membrane potential， downregulated protein levels of p-Akt， PKM2， GLUT1， PDK1， PDH， and LDHA， and reduced PDK1 and p-Akt fluorescence intensity （P<0.05）. Compared with the siPDK1+Buzhong Yiqitang group， the siPDK1+cisplatin group showed decreased colony formation rate， downregulated protein levels of p-Akt and PDH， and reduced PDK1 and p-Akt fluorescence intensity （P<0.05）. The siPDK1+cisplatin+Buzhong Yiqitang group exhibited decreased colony formation rate， reduced lactate production， increased ATP production， lowered mitochondrial membrane potential， downregulated protein levels of p-Akt， GLUT1， PDH， and LDHA， and reduced PDK1 and p-Akt fluorescence intensity （P<0.05）. Compared with the siPDK1+cisplatin group， the siPDK1+cisplatin+Buzhong Yiqitang group showed decreased colony formation rate， increased ATP production， and downregulated protein levels of p-Akt， PKM2， and LDHA （P<0.05）. ConclusionBuzhong Yiqitang combined with cisplatin can suppress lung adenocarcinoma cell proliferation by modulating glycolysis through the PDK1/Akt signaling pathway.

ObjectiveTo explore the changes in volatile components， total polysaccharides， enzyme activity， and chromaticity value of Myristicae Semen Koji（MSK） during the fermentation process， and conduct correlation analysis. MethodsBased on gas chromatography-mass spectrometry（GC-MS）， the changes of volatile components in MSK at different fermentation times were identified. The phenol sulfuric acid method， dinitrosalicylic acid method（DNS）， and carboxymethyl cellulose sodium salt method（CMC-Na） were used to investigate the total polysaccharide content， amylase activity， and cellulase activity during the fermentation process. Visual analysis technology was used to explore the changes in chromaticity values， revealing the fermentation process of MSK and the dynamic changes of various measurement indicators， partial least squares-discriminant analysis（PLS-DA） was used to explore the differential compounds of MSK at different fermentation degrees， and Pearson correlation analysis was used to explore the correlation between volatile components of MSK and total polysaccharides， enzyme activity， and chromaticity values. ResultsA total of 60 volatile compounds were identified from MSK， the relative contents of components such as （+）-α-pinene， β-phellandrene， β-pinene， （+）-limonene， and p-cymene obviously increased， while the relative contents of components such as safrole， methyl isoeugenol， methyleugenol， myristicin， and elemicin significantly decreased. During the fermentation process， the total polysaccharide content showed an upward trend， while the activities of amylase and cellulase showed an initial increase followed by a decrease， and reached their maximum value at 40 h. the overall brightness（L^*） and total color difference（ΔE^*） gradually increased， while the changes in red-green value（a^*） and yellow-blue value（b^*） were not obvious. PLS-DA results showed that MSK could be clearly distinguished at different fermentation times， and 13 differential biomarkers were screened out. Pearson correlation analysis results showed that the contents of α-terpinene， β-phellandrene， methyleugenol， β-cubebene and myristic acid had an obvious correlation with chromaticity values. ConclusionAfter fermentation， the volatile components， total polysaccharides， amylase activity， and cellulase activity of MSK undergo significant changes， and there is a clear correlation between them and chromaticity values， which reveals the dynamic changes in the fermentation process and related indicators of MSK， laying a foundation for the quality control.

Objective:To investigate the G/P genotypes of group A rotavirus（RVA）in the 2023 sentinel surveillance in Jiangsu Province，and to conduct a molecular characterization analysis of the whole-genome sequences of four G9P［4］genotype RVA strains identified during surveillance.Methods:A total of 212 RVA-positive specimens collected from the surveillance system in 2023 were subjected to G/P genotyping using multiplex nested RT-PCR. Whole-genome sequencing was performed on six G9P［4］strains. The resulting complete genome sequences were preliminarily genotyped using BLAST，followed by comprehensive molecular characterization analyses utilizing BioEdit 7.0.5，MAFFT，MEGA 7.0，and iTOL software.Results:The overall RVA positivity rate was 6.22%. The predominant G/P combination in both outpatient and inpatient settings was G8P［8］. Among the six G9P［4］strains，four were successfully sequenced. All four exhibited the genotype constellation G9-P［4］-I2-R2-C2-M2-A2-N1-T2-E2-H2. While the NSP2 gene belonged to the N1 genotype，all other genes corresponded to the DS-1-like genogroup. Phylogenetically，the four Jiangsu G9P［4］strains clustered within Lineage V of the VP7 gene and formed a distinct minor subclade within the N1 branch of the NSP2 gene. Unique amino acid substitutions were identified at multiple VP7 neutralization antigenic epitope sites when compared to vaccine strains.Conclusions:The predominant circulating RVA strain in Jiangsu province during 2023 was G8P［8］. Concurrently，the relatively uncommon G9P［4］-N1 strain was detected. This strain exhibited significant amino acid differences at key epitopes compared to vaccine strains. Enhancing the proportion of whole-genome sequencing in RVA surveillance is warranted to obtain more detailed genetic information，thereby providing crucial data to support future vaccine development and optimization strategies.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

ObjectiveTo evaluate the effect and safety of Jiuxin Pill （救心丸） on exercise tolerance and quality of life in patients with stable angina pectoris （SAP）. MethodsA randomised， double-blind， placebo-controlled， multicentre study design was used to enroll 170 patients of SAP from nine centres， which were divided into 85 patients each in the trial group and control group with 1∶1 ratio. Both groups maintained the original western medicine treatment plan， and added Jiuxin Pill or placebo respectively， 2 pills （0.05 g） each time twicely for 28 days. The main outcomes were total exercise time （TED） in the exercise treadmill test and Seattle Angina Questionnaire （SAQ） scores including physical limitation （PL）， angina stability （AS）， angina frequency （AF）， treatment satisfaction （TS）， and disease perception （DP）. The secondary outcomes were exercise treadmill test indicators including heart rate recovery in 1 min （HRR1）， metabolic equivalents （METs）， maximum magnitude of ST-segment depression， and the Borg rating of perceived exertion scale， the average number of angina attacks per week， withdrawal and reduction rate of nitroglycerin， traditional Chinese medicine syndrome scores， incidence of major adverse cardiovascular events. Safety indicators were evaluated and the occurrence of adverse events during the trial was recorded. Data was collected before treatment， day 28±2 in treatment period， and follow-up at day 56 which is 28±2 days after treatment period finished. ResultsEighty-four and eighty-five patients respectively from trial group and control group were included to the full analysis set （FAS） and safety analysis set （SS）. Compared with the group before treatment and with the control group after treatment， the trial group had higher TED， HRR1， and METs， and lower maximum magnitude of ST-segment depression and Borg rating of perceived exertion scores after treatment （P＜0.01）. Compared with the group before treatment and with the control group after treatment and at follow-up， the total SAQ score and scores of AS， AF， TS and DP of the trial group after treatment and at follow-up elevated， while the average number of angina attacks per week and traditional Chinese medicine syndrome scores reduced （P＜0.01）. There was no statistically significant difference in the withdrawal and reduction rate of nitroglycerin between groups （P＞0.05）. Major adverse cardiovascular events occurred in 1 case （1/84， 1.19%） in the trial group and 1 case （1/85， 1.18%） in the control group， and the difference between groups was not statistically significant （P＞0.05）. A total of 3 cases of adverse events occurred in the trial group （3/84， 3.57%）， and a total of 6 cases of adverse events occurred in the control group （6/85， 7.06%）， and there was no statistically significant difference in the incidence of adverse events between groups （P＞0.05）. ConclusionIn the treatment of SAP， Jiuxin Pill combined with conventional western medicine can further enhance exercise tolerance， improve quality of life， and demonstrate great safety.

Objective To investigate the expression of Thymosinβ10(TMSB10)in gastric cancer and its molecular mechanism in promoting the progression of gastric cancer.Methods We collected pathological sections of 70 patients with gastric cancer in our hospital,detected expression of TMSB10 in gastric adenocarcinoma by immunohistochemistry,and analyzed its prognostic effect.In order to study the mechanism of action,the effects of TMSB10 on the proliferation and glycolysis of gastric cancer cells and its related mechanism were observed by trans-fection technique,CCK8 test,EDU assay,Transwell assay,scratch test,glycolysis assay and Western blot.Results Immunohistochemistry showed that TMSB10 was highly expressed in gastric cancer,while the expression level of TMSB10 was correlated with tumor size(P=0.032),TNM stage(P=0.002)and distant metastasis.In the mechanism study,we found that overexpression of TMSB10 promoted the proliferation,invasion,migration and glycolytic phenotype of gastric cancer cells through in vitro CCK-8 test,EDU assay,Transwel assay and glycolysis assay,and vice versa.Western blot results showed that overexpression of TMSB10 may regulate the occurrence of gastric cancer through up-regulation of the AMPK/mTOR signaling pathway.Conclusions TMSB10 promotes the proliferation,invasion,migration and glycolysis gastric cancer through the AMPK/mTOR signaling pathway.
