It is very limited that the benefit of perioperative chemotherapy in early non-small cell lung cancer (NSCLC), and the 5-year survival rate is only 5% higher than surgery. Antibodies that block programmed cell death protein 1/programmed death-ligand 1 significantly improve the survival of advanced NSCLC. The value of immunotherapy in early NSCLC is also being explored. This paper firstly summarized and analyzed the progress of immunotherapy in the perioperative period of NSCLC. Secondly, the safety and feasibility of surgical resection after neoadjuvant immunotherapy were discussed. Finally, the clinical value of different therapeutic efficacy prediction indicators was summarized, in order to clarify the current status of immunotherapy in the perioperative period, so as to improve the clinical benefits of early NSCLC patients.

This article systematically analyzed the historical evolution of the origin, scientific name, producing area, quality evaluation, harvesting and processing, and other aspects of Quisqualis Fructus by consulting the ancient materia medica, medical books, prescription books, local literature and combining with the modern literature and standards, summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes, in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty, and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty, which has been consistently used throughout subsequent dynasties, and there were also aliases such as Junziren, Sijunzi, and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica, a plant belonging to the family Combretaceae. In modern times, its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007, the Flora of China(English edition) designated Q. indica var. villosa as a synonym of Q. indica. Today, the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records, the producing areas of Quisqualis Fructus were Guangdong, Hong Kong, Macao, Guangxi, Hainan, Sichuan and Fujian, and then gradually expanded to Yunnan, Taiwan, Jiangxi and Guizhou. Since the Song dynasty, two major production regions have gradually emerged in Sichuan, Chongqing and Fujian. Currently, it is primarily cultivated in Chongqing, Guangxi and other areas, with Chongqing yielding the highest output. Since modern times, superior quality has been defined by large size, a purple-black surface, plump grains, and a yellowish-white kernel. According to ancient herbal records, the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar, mostly used raw after shelling or with the shell intact, it underwent processing methods such as cleaning, slicing, mixing, steaming, roasting, stewing, and frying. Currently, the harvesting period is autumn, followed by sun-drying or low-heat drying, with processing methods including cleaning, stir-frying, and stewing. In ancient and modern literature, the records of the properties, functions and indications of Quisqualis Fructus are basically the same, that is, sweet in taste, warm in nature, predominantly non-toxic, belonging to the spleen and stomach meridians. It possesses effects of insecticide, decontamination and invigorating spleen for ascariasis, enterobiasis, abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations, limiting use for those with spleen-stomach deficiency-cold, refraining from drinking hot tea during medication, and avoiding excessive intake. Based on the textual research, it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements, and the raw products is recommended for medicinal use if not specified.

ObjectiveTo integrate network pharmacology prediction with multi-level experimental verification methods, and to explore in depth the therapeutic efficacy and potential mechanism of luteolin in treating gout. MethodsDatabases were used to obtain potential pharmacodynamic targets of luteolin. Protein-protein interaction (PPI) network construction and network pharmacology analysis techniques were used to screen key core targets of luteolin in gout treatment. Further biological function enrichment analysis and signaling pathway analysis were performed on these targets. Molecular docking simulation was used to calculate the binding energy between luteolin and potential core targets, clarifying the strength of their interactions. In the in vivo experiment for hyperuricemia, 48 mice were randomly divided into a blank group, a model group, an allopurinol group (5 mg·kg-1), and low-dose (10 mg·kg-1), medium-dose (30 mg·kg-1), and high-dose (90 mg·kg-1) luteolin groups. For the first three days, the blank and model groups were gavaged with an equal volume of normal saline, while the allopurinol group and luteolin groups were gavaged with corresponding drugs. From day 4 onwards, modeling was performed by intraperitoneal injection at 12:00 daily (normal saline for the blank group, and oxonic acid potassium-hypoxanthine mixture for other groups, with 300 mg·kg-1 for each group). Gavage intervention was administered at 18:00 daily (normal saline for the blank/model groups, and corresponding drugs for the treatment groups) until day 7. After sampling, levels of serum uric acid (UA), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured. Levels of xanthine oxidase (XO) in the liver and kidney, ATP-binding cassette transporter G2 (ABCG2) and malondialdehyde (MDA) in the kidney, and superoxide dismutase (SOD) in the liver were determined. Renal HE staining was also performed. In the pharmacodynamic study of gouty arthritis, 36 rats were randomly divided into a blank group, a model group, a colchicine group (0.315 mg·kg-1), and low-dose (7 mg·kg-1), medium-dose (21 mg·kg-1), and high-dose (63 mg·kg-1) luteolin groups. The model was established by vertically injecting 100 µL of 25 g·L-1 monosodium urate suspension into the posterior lateral aspect of the right ankle joint (the blank group was injected with an equal volume of normal saline), with repeated injections every two days for reinforcement. From day 2 after modeling, daily gavage administration was performed (normal saline for the blank/model groups, and corresponding drugs for the treatment groups) for a total of 16 days. During the experiment, ankle swelling and pain threshold were measured regularly. After sampling, levels of serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) were determined. Ankle joints were subjected to HE, Masson, and safranin O-fast green staining, and HE staining was also performed on ankle synovial tissue and various organs. Western blot was used to determine the expression levels of key proteins in gout-related signaling pathways. ResultsNetwork pharmacology analysis predicted that luteolin may regulate over 20 core targets, such as XO, ABCG2, nuclear factor erythroid 2-related factor 2 (Nrf2), and SOD, through acting on signaling pathways including NF-κB, phosphoinositide 3-kinase/protein kinase B (PI3K/Akt), and ABC transporters, thereby affecting uric acid metabolism and inflammatory responses. In the hyperuricemia model, compared with the blank group, the model group showed significantly increased serum UA level, liver and kidney XO activity, renal ABCG2 expression, and liver SOD activity (P<0.01). Compared with the model group, the high-dose luteolin group significantly reduced serum UA level (P<0.01), inhibited liver and kidney XO activity (P<0.01), and significantly increased renal ABCG2 expression and liver SOD activity (P<0.01), effectively alleviating renal oxidative stress damage and improving renal histopathological status. In the gouty arthritis model, compared with the blank group, the model group showed significant ankle swelling, decreased pain threshold, and significantly increased levels of IL-6, IL-1β, and TNF-α in serum and synovial tissue (P<0.01). The high-dose luteolin group significantly reduced ankle swelling, prolonged hot plate pain threshold, effectively decreased the levels of the above inflammatory factors in serum and synovial tissue (P<0.01), and significantly improved ankle pathological damage, showing good analgesic and anti-inflammatory effects. Western blot results further confirmed that luteolin significantly upregulated Nrf2 protein expression and downregulated XO and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) expression in animals. ConclusionLuteolin can improve symptoms of hyperuricemia and gouty arthritis, and its potential mechanism may be related to inhibiting XO activity, increasing ABCG2 and SOD levels, and regulating Nrf2-mediated oxidative stress-related pathways.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).

OBJECTIVE To comprehensively evaluate the different drying methods of Metapanax delavayi based on multi-index dimensions, including sun drying (SD), shade drying (ND), hot air drying (HAD), vacuum drying (VD), and vacuum freeze drying (VFD). METHODS An electronic eye was used to evaluate the appearance of samples with five drying methods. An electronic tongue was used to evaluate taste. The microstructure was evaluated by scanning electron microscope. The contents of moisture, total ash, acid-insoluble ash and water-soluble extract were detected by the methods in Chinese Pharmacopoeia . The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, 3,5- O -dicaffeoylquinic acid and 4,5- O -dicaffeoylquinic acid were determined by high-performance liquid chromatography. The comprehensive quality evaluation of five samples based on chemometrics, entropy weight-technique for order preference by similarity to ideal solution (TOPSIS) and grey relational analysis (GRA) with the above indicators as variables, the key indicators affecting the qualit y were screened by variable importance in projection (VIP) >1.0. RESULTS The color results of five samples showed that average L * , a * , b * ranged from 47.532 to 56.986, -4.957 to -0.718, 19.313 to 28.194, respectively. The taste results of the five samples showed that the presented high response values were for sourness and bitterness. Microstructural observation demonstrated that the ND samples showed smooth surfaces with compact texture; SD samples exhibited rough surfaces with obvious cracks; VD samples showed relatively rough surfaces with layered stacked morphology; HAD samples showed loose and coarse structures; VFD samples showed relatively smooth surfaces. The average moisture content ranged from 7.064% to 8.513%, the average total ash content ranged from 5.214% to 5.706%, the average acid-insoluble ash content ranged from 0.576% to 0.720%, and the average water-soluble extract content ranged from 26.081% to 28.395%. The contents of the five constituents were 2.559-8.940, 8.731-21.037, 1.710-4.479, 1.967-6.130, 1.199-2.001 mg/g, respectively. The results of cluster analysis and orthogonal partial least squares-discriminant analysis showed that the five samples were divided into three categories, both the VFD sample and HAD sample were clustered into one category, and the other samples were clustered into one category. The VIP values of chlorogenic acid, L * , b * , 3,5- O -dicaffeoylquinic acid, neochlorogenic acid and a * were higher than 1.0. The results of the entropy weight-TOPSIS method combined with GRA showed that the comprehensive closeness coefficients of the five samples were 0.414, 0.488, 0.412, 0.452 and 0.563, respectively. CONCLUSIONS Among the five drying samples, the quality of VFD sample was the best. Chlorogenic acid, L * , b * , 3,5- O -dicaffeoylquinic acid, neochlorogenic acid and a * were the key indicators to distinguish the quality of the different drying methods of M. delavayi .

ObjectiveTo describe the prevalence and dynamic pain characteristics of dysmenorrhea among female medical students through a menstrual diary-based observational study. MethodsFrom April to June 2021, female students were recruited from a medical college in Shanghai to complete menstrual diaries and record dysmenorrhea-related characteristics for two menstrual cycles. Dysmenorrhea severity was assessed using the visual analogue scale (VAS) (no pain: 0; mild: 1‒3; moderate: 4‒6; severe: 7‒10). A total of 323 diaries were collected, of which 303 were 93.81% valid (valid response rate: 93.81%), covering 596 complete menstrual cycles. Among them, 293 participants completed diaries for two cycles and were included in the analysis of persistent dysmenorrhea. Period, point, and persistent prevalence of dysmenorrhea were calculated using the number of participants as the denominator. Paired comparisons were performed using Cochran’s Q test and Bonferroni-adjusted McNemar tests. Using menstrual cycles with dysmenorrhea as the unit of analysis, the distributions of pain onset, peak timing, and pain duration across different severities were compared using the χ² tests or Fisher’s precision probability tests. ResultsAmong 303 female college students, 269 experienced dysmenorrhea during the first recorded cycle, and 288 had dysmenorrhea in any cycle. Among 596 complete menstrual cycles recorded, 527 were associated with dysmenorrhea (88.42%), and among 293 students who completed 2 complete recorded cycles, 239 had persistent dysmenorrhea. The period, point, and persistent prevalence of dysmenorrhea among female college students were 95.05% (288/303), 88.78% (269/303), and 81.57% (239/293), respectively (Q=61.61, P<0.001). The prevalence of persistently severe dysmenorrhea was 5.12% (15/293). Among the 527 dysmenorrheic cycles, there were statistically significant differences in the distribution of pain onset time (P=0.003) and pain duration (P<0.001) among different degrees of dysmenorrhea; mild dysmenorrhea mostly started on the first day of menstruation (52.83%), and moderate dysmenorrhea mostly started before menstruation (50.19%). Pain duration increased with severity; the proportions of cycles with pain lasting ≥4 days were 13.20%, 43.03%, and 51.56% for mild, moderate, and severe dysmenorrhea cycles, respectively. For all severity groups, mean pain scores peaked on the first day of menstruation and then decreased day by day to a stable level. ConclusionDysmenorrhea is highly prevalent among female medical students, and differences exist across pain severity levels in onset time, duration, and dynamic changes in pain. Identification and health guidance for those with persistently moderate-to-severe dysmenorrhea should be strengthened, and medical evaluation should be conducted when necessary.

ObjectiveTo investigate the clinical effects and safety of Shuhe Granules (舒和颗粒) in patients with rheumatoid arthritis (RA) comorbid with insomnia. MethodsA single-arm prospective exploratory design was adopted. Thirty RA patients comorbid with insomnia and diagnosed with the traditional Chinese medicine (TCM) syndrome of kidney-heart deficiency and qi-blood disharmony were enrolled. On the basis of maintaining their original RA treatment regimens, all patients received oral Shuhe Granules, one dose per day, for 12 consecutive weeks. The outcomes were assessed before treatment and at weeks 4, 8, and 12 after treatment. Sleep and related psychosomatic function were evaluated using the insomnia severity index (ISI), Pittsburgh sleep quality index (PSQI), fatigue severity scale (FSS), patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7), and Montreal cognitive assessment (MoCA) scores. RA-related assessments included the 28-joint disease activity score based on C-reactive protein (DAS28-CRP), pain visual analog scale (VAS), tender joint count (TJC28), swollen joint count (SJC28), morning stiffness duration, and health assessment questionnaire (HAQ) score. Laboratory parameters included erythrocyte sedimentation rate (ESR), serum C-reactive protein (CRP), anti-cyclic citrullinated peptide antibody (anti-CCP), and rheumatoid factor (RF) levels. A literature-based historical control group was established through literature retrieval and meta-analysis. The ISI, PSQI, DAS28-CRP, and pain VAS scores were compared between the treatment group in the present study and the historical control group. Safety assessments were also performed. ResultsCompared with baseline before treatment, ISI and PSQI scores decreased at weeks 4, 8, and 12, while MoCA scores increased at weeks 4, 8, and 12. FSS scores decreased at weeks 4 and 12. At weeks 8 and 12, GAD-7 scores, DAS28-CRP scores, duration of morning stiffness, TJC28, and SJC28 were reduced. At week 12, PHQ-9, pain VAS, and HAQ scores significantly decreased (P<0.05). FSS and DAS28-CRP scores at week 12 were lower than those at week 4, and CRP levels at week 8 were lower than those at week 4 (P<0.05). Compared with the historical control group, the treatment group showed superior improvement in ISI and PSQI scores (P<0.001); however, no statistically significant differences were observed between the two groups in DAS28-CRP or pain VAS scores (P>0.05). No serious adverse events occurred during the study, and the 4 reported mild adverse events were all considered unrelated to the study medication. ConclusionShuhe Granules significantly improve sleep quality, fatigue, emotional status, cognitive function, RA-related symptoms, and joint function in patients with RA comorbid insomnia, with good safety and tolerability.

[Objective] To investigate the implementation of emergency transfusion strategy of uncrossmatched type O suspended RBCs based on the single-center clinical practice, which is "emergency transfusion is initiated by the authorized doctor of the emergency department, and no more than 4 U of type O uncrossmatched suspended RBCs are issued within 15 minutes in the transfusion department"(referred as the Practice), so as to provide reference for blood management. [Methods] A retrospective analysis of the information of patients who received uncrossmatched type O suspended RBCs in West China Hospital of Sichuan University from August 2019 to April 2024 was conducted. The analysis included reasons for emergency blood transfusion, time of receiving transfusion application and blood distribution, total bilirubin, indirect bilirubin, lactate dehydrogenase before and after transfusion, blood group of patients, and disease outcome. [Results] From August 2019 to April 2024, 39 cases applied for emergency transfusion of type O suspended RBCs, and a total of 90 U uncrossmatched suspended RBCs were transfused. All patients were Rh(D) positive, including 14 cases of blood group A, 6 cases of blood group B, 16 cases of blood group O, 2 cases of blood group AB, one case of undetermined blood group, and 2 cases with positive antibody screening. The main cause of emergency transfusion of type O suspended RBCs was traffic accident, accounting for 46% (18/39), with a mortality rate at 51.28% (20/39). The cause of death was primary injury, and no adverse reactions were reported. There was no significant difference in total bilirubin (TBIL), indirect bilirubin (IBIL) and lactate dehydrogenase (LDH) before and after blood transfusion (P>0.05). The median duration from admission to receiving transfusion application was 30.20 minutes, and 5.30 minutes from receipt of the application to blood distribution. [Conclusion] The single-center based Practice is safe, but there is room for optimization before the link of blood transfusion application sent to the transfusion department when applying for emergency transfusion of type O suspended RBCs.

ObjectiveTo explore effect of Xianlian Jiedu prescription on the recurrence of colorectal cancer (CRC) and investigate the related mechanisms. MethodsA postoperative recurrence model was established in 25 Balb/c mice by injecting CT26 cells subcutaneously into the armpit, followed by surgical removal of 99% of the subcutaneous tumor. The mice were randomly divided into model group, low-dose Xianlian Jiedu prescription (XLJDP-L) group (6.45 g·kg-1·d-1), medium-dose Xianlian Jiedu prescription (XLJDP-M) group (12.9 g·kg-1·d-1), high-dose Xianlian Jiedu prescription (XLJDP-H) group (25.8 g·kg-1·d-1), and 5-fluorouracil (5-FU) group (1×10-3 g·kg-1·d-1). The mice were euthanized after 14 days of continuous intervention, and recurrent tumor tissue was harvested. Hematoxylin and eosin (HE) staining was used to observe pathological and morphological changes in the recurrent tumor tissue. Immunohistochemistry (IHC) was employed to assess the expression of proliferating cell nuclear antigen (Ki67), vascular endothelial growth factor (VEGF), and platelet-endothelial cell adhesion molecule (CD31) in recurrent tumor tissue. The Western blot was used to detect the protein expression levels of angiopoietin-2 (ANG-2), VEGF, phosphorylated-protein kinase B (p-Akt), protein kinase B (Akt), phosphorylated-phosphatidylinositol 3-kinase (p-PI3K), and phosphatidylinositol 3-kinase (PI3K) in recurrent tumor tissue. ResultsBefore treatment, there were no statistical differences in tumor volume, tumor weight, and body mass among the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group compared to the model group, indicating model stability. After treatment, compared with those in the model group, the tumor volume and tumor weight in the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly reduced (P<0.01), showing dose dependency. Meanwhile, there were no significant differences in body weight among the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group compared to the model group. HE staining showed that compared with that in the model group, tumor tissue in the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group had loosely arranged cells, increased intercellular spaces, small and shriveled nuclei, light staining, fewer mitotic figures and atypical nuclei, and increased necrotic areas. IHC showed that compared with those of the model group, the positive rates of Ki67, VEGF, and CD31 in the recurrent tumor tissue of the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly reduced (P<0.01) in a dose-dependent manner. Western blot results showed that compared with those of the model group, the protein expression levels of ANG-2 and VEGF in the recurrent tumor tissue of the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly downregulated (P<0.05, P<0.01), and the p-Akt/Akt and p-PI3K/PI3K ratios were significantly decreased in a dose-dependent manner (P<0.05, P<0.01). ConclusionXianlian Jiedu prescription significantly inhibits the recurrence of CRC in mice after subcutaneous tumor surgery. The mechanism may involve regulating the PI3K/Akt pathway and downregulating key angiogenic proteins such as ANG-2, VEGF, and CD31.

ObjectiveTo investigate the inhibitory effect of Biejia Decoction Pill on the proliferation, migration, and aerobic glycolysis of hepatocellular carcinoma (HCC) using cell experiments, as well as related mechanisms. MethodsHuman liver cancer cell line Huh7 was selected, and Sprague-Dawley rats were randomly divided into blank serum group, inhibitor group, and high-, middle-, and low-dose Biejia Decoction Pill groups. Rat serum containing the drug was prepared for the incubation of Huh7 cells. CCK8 assay and scratch assay were used to explore the effect of Biejia Decoction Pill on the proliferation and migration of HCC cells; glycolytic rate-limiting enzymes and metabolites were measured to explore the effect of Biejia Decoction Pill on aerobic glycolysis of liver cancer cells; RT-qPCR and Western blot were used to explore the effect of Biejia Decoction Pill on the mRNA expression, related proteins, and phosphorylation of the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test or the Dunnett’s T3 test were used for further comparison between two groups. ResultsCompared with the blank serum group, the Biejia Decoction Pill groups had significant reductions in OD value, migration rate during different periods of time, glycolytic rate-limiting enzymes (hexokinase, phosphofructokinase, pyruvate kinase), and glycolytic metabolites (pyruvate, lactic acid, ATP) (all P<0.05). RT-qPCR results showed that compared with the blank serum group, the high-, middle-, and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of mTOR, and the high- and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of AKT (all P<0.05). Western blot results showed that compared with the blank serum group, the high-, middle-, and low-dose Biejia Decoction Pill groups had significant reductions in the expression levels of mTOR-related proteins and phosphorylated proteins, and the high- and middle-dose Biejia Decoction Pill groups had significant reductions in the expression levels of AKT-related proteins and phosphorylated proteins (all P<0.05). ConclusionThis study preliminarily verifies that the serum containing Bijia Decoction Pill can inhibit the aerobic glycolysis of human hepatoma Huh7 cells, thereby inhibiting their proliferation and migration, possibly by inhibiting the expression of the proteins related to the AKT/mTOR signaling pathway.
