ObjectiveTo investigate the mechanism of action of Kaixinsan in the treatment of Alzheimer's disease (AD) based on network pharmacology, molecular docking, and animal experimental validation. MethodsThe Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and the Encyclopedia of Traditional Chinese Medicine(ETCM) databases were used to obtain the active ingredients and targets of Kaixinsan. GeneCards, Online Mendelian Inheritance in Man(OMIM), TTD, PharmGKB, and DrugBank databases were used to obtain the relevant targets of AD. The intersection (common targets) of the active ingredient targets of Kaixinsan and the relevant targets of AD was taken, and the network interaction analysis of the common targets was carried out in the STRING database to construct a protein-protein interaction(PPI) network. The CytoNCA plugin within Cytoscape was used to screen out the core targets, and the Metascape platform was used to perform gene ontology(GO) functional enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis. The “drug-active ingredient-target” interaction network was constructed with the help of Cytoscape 3.8.2, and AutoDock Vina was used for molecular docking. Scopolamine (SCOP) was utilized for modeling and injected intraperitoneally once daily. Thirty-two male C57/BL6 mice were randomly divided into blank control (CON) group (0.9% NaCl, n=8), model (SCOP) group (3 mg·kg-1·d-1, n=8), positive control group (3 mg·kg-1·d-1 of SCOP+3 mg·kg-1·d-1 of Donepezil, n=8), and Kaixinsan group (3 mg·kg-1·d-1 of SCOP+6.5 g·kg-1·d-1 of Kaixinsan, n=8). Mice in each group were administered with 0.9% NaCl, Kaixinsan, or Donepezil by gavage twice a day for 14 days. Morris water maze experiment was used to observe the learning memory ability of mice. Hematoxylin-eosin (HE) staining method was used to observe the pathological changes in the CA1 area of the mouse hippocampus. Enzyme linked immunosorbent assay(ELISA) was used to determine the serum acetylcholine (ACh) and acetylcholinesterase (AChE) contents of mice. Western blot method was used to detect the protein expression levels of signal transducer and activator of transcription 3(STAT3) and nuclear transcription factor(NF)-κB p65 in the hippocampus of mice. ResultsA total of 73 active ingredients of Kaixinsan were obtained, and 578 potential targets (common targets) of Kaixinsan for the treatment of AD were screened out. Key active ingredients included kaempferol, gijugliflozin, etc.. Potential core targets were STAT3, NF-κB p65, et al. GO functional enrichment analysis obtained 3 124 biological functions, 254 cellular building blocks, and 461 molecular functions. KEGG pathway enrichment obtained 248 pathways, mainly involving cancer-related pathways, TRP pathway, cyclic adenosine monophosphate(cAMP) pathway, and NF-κB pathway. Molecular docking showed that the binding of the key active ingredients to the target targets was more stable. Morris water maze experiment indicated that Kaixinsan could improve the learning memory ability of SCOP-induced mice. HE staining and ELISA results showed that Kaixinsan had an ameliorating effect on central nerve injury in mice. Western blot test indicated that Kaixinsan had a down-regulating effect on the levels of NF-κB p65 phosphorylation and STAT3 phosphorylation in the hippocampal tissue of mice in the SCOP model. ConclusionKaixinsan can improve the cognitive impairment function in SCOP model mice and may reduce hippocampal neuronal damage and thus play a therapeutic role in the treatment of AD by regulating NF-κB p65, STAT3, and other targets involved in the NF-κB signaling pathway.

ObjectiveTo explore the clinical efficacy and safety of Da Chaihutang (DCH) for the treatment of sepsis with Yang syndrome. MethodsA total of 70 patients suffering from sepsis with Yang syndrome were randomly divided into an observation group and a control group, with 35 cases in each group. They both received standard Western medicine treatment. The observation group was additionally given a dose of DCH, which was boiled into 100 mL and taken twice. The control group was additionally given an equal volume and dosage of warm water. The intervention lasted for three days. The 28-day all-cause mortality and the changes in the following indicators before and after intervention were compared between the two groups, including sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,white blood cell (WBC),the percentage of neutrophils (NEU%),C-reactive protein (CRP),procalcitonin (PCT),alanine transaminase (ALT),aspartate transaminase (AST),total bilirubin (TBil),creatinine (Cr),blood urea nitrogen (BUN),acute gastrointestinal injury (AGI) grade,gastrointestinal dysfunction score (GDS),serum intestinal fatty acid-binding protein (iFABP), citrulline (CR),platelet (PLT),prothrombin time(PT),activated partial thromboplastin time (APTT),fibrinogen (Fib),international normalized ratio (INR),and D-dimer (D-D). ResultsThere was no significant difference between the two groups regarding 28-day all-cause mortality. After the intervention,SOFA,WBC,PCT,and Cr were significantly decreased, and PLT was significantly increased in the control group (P<0.05). SOFA,APACHE Ⅱ,NEU%,CRP,PCT,ALT,AST,Cr,BUN,AGI grade,GDS,and serum iFABP and CR were significantly improved in the observation group (P<0.05). After the intervention,APACHE Ⅱ,PCT,AGI grade,GDS,and serum iFABP in the observation group were significantly lower than those in the control group ,while CR and PLT were higher (P<0.05,P<0.01). There were significant differences regarding the gap of SOFA,APACHE Ⅱ,AST,TBil,AGI grade,GDS,iFABP,CR, and PLT between the two groups (P<0.05,P<0.01). There were slight differences regarding PT,APTT,Fib,INR,and D-D between the two groups,which were in the clinical normal range. ConclusionOn the basis of Western medicine, DCH helped to reduce sepsis severity and improved multiple organ dysfunction with high clinical efficacy and safety, but further research on its impact on the prognosis of patients with sepsis is still required.

AIM: To investigate the alterations in corneal aberration and relative refractive power following the reduction of back optic zone diameters(BOZD)of orthokeratology lenses.METHODS: Myopic children aged 8-12 years, deemed suitable and willing to wear orthokeratology lenses, were randomly allocated to wear lenses with a 6.0 mm BOZD or a 5.0 mm BOZD. Data collection included changes in higher-order aberrations, relative refractive power and the treatment zone diameter of the two groups after wearing lenses for 1 d, 1 wk, 1, and 3 mo. The correlation of increase in corneal higher-order aberrations with refractive power was analyzed.RESULTS: The increases in total higher-order aberrations, spherical aberrations and coma aberrations varied over time following lens wear(all P<0.001), and there were no statistically significant differences in the changes of total higher-order aberrations and coma aberrations between the two groups of patients(all P>0.05). A significant difference was observed in the increment of spherical aberrations in the 5 mm range between the two groups of patients, which varied over time(Ftime=40.179, Ptime<0.001; Fgroup=11.948, Pgroup=0.001; Finteraction=3.262, Pinteraction=0.03). A significant difference was observed in the increment of spherical aberrations in the 4 mm range between the two patient groups(Ftime=34.462, Ptime<0.001; Fgroup=13.094, Pgroup<0.001; Finteraction=1.372, Pinteraction=0.25). There was no statistically significant distinction in relative refractive power between the two groups(Fgroup=0.048, Pgroup=0.83; Finteraction=1.208, Pinteraction=0.31); however, relative refractive power changed over time(Ftime=40.030, Ptime<0.001). The difference in treatment zone diameter between the two groups was statistically significant, with changes over time(Ftime=11.212, Ptime<0.001; Fgroup=74.073, Pgroup<0.001; Finteraction=0.312, Pinteraction=0.82). The total higher-order aberrations, spherical aberrations, and coma aberrations in 4, 5 and 6 mm range showed a positive correlation with relative refractive power values(all P<0.001). Statistically significant difference was observed in the axial length between the two groups after wearing lenses for 3, 6 and 12 mo(Ftime=185.398, Ptime<0.001; Fgroup=5.618, Pgroup=0.02; Finteraction=2.315, Pinteraction=0.11).CONCLUSION: Orthokeratology lenses leaded to elevated higher-order aberrations. Orthokeratology lenses with smaller BOZD produced significantly greater spherical aberrations at 4 and 5 mm range and smaller treatment zone diameters. The corneal total higher-order aberration was positively correlated with relative refractive power. Wearing orthokeratology lenses with a smaller BOZD can cause slower axial growth and better myopia control.

In recent years, hyperuricemia (HUA) has shown a rapidly increasing incidence and tends to occur in increasingly young people, with a wide range of cardiac, renal, joint, and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage, medication restriction, and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid (UA), and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology, which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine (TCM) can treat HUA via multiple targets and multiple pathways from a holistic view, with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However, its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA, this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora, intestinal metabolites, intestinal UA transporters, and intestinal barriers. Furthermore, we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology, with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions (Second Batch). This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution, efficacy, indications, dosage decoctions, and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty, but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma, 619.5 g of Puerariae Lobatae Radix, 413 g of Paeoniae Radix Alba, and 413 g of Glycyrrhizae Radix et Rhizoma, which are ground into coarse powder. Each dose is 12.39 g, and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome, penetrating pathogenic factors, and detoxicating together. Its indications are widely involved in internal medicine, pediatrics, surgery, ophthalmology and otorhinolaryngology, obstetrics and gynecology, sexually transmitted diseases, and other diseases, such as measles, sores, acne, spots, surgical gangrene, red eyes, toothache, chancre, and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated, including rash, pox, macula, numbness, summer diarrhea, dysentery, sha disease, febrile symptoms, spring warmth, winter warmth, and cold pestilence. At the same time, it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications, it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system, nervous system, pediatric-related diseases and syndromes, skin system, hepatobiliary system, and digestive system. It plays a key role in the treatment of epidemic diseases such as measles, chronic hepatitis B, dysentery, and tetanus.

[Objective] To compare next generation sequencing (NGS) library construction technology between probe hybridization capture and amplicon methods, and analyze the influencing factors of HLA genotyping resolution level and its prospects in clinical applications. [Methods] A total of 207 clinical samples with known typing results and samples from the proficiency testing plan were selected. The conformity rate of HLA genotyping results, allele coverage and typing data analysis indicators were confirmed, and the effects of two library construction methods on the level of HLA genotyping discrimination were compared. [Results] The concordance rate of 207 samples with the feedback results of PT or prior well-characterized HLA genotypes was 100%. Among them, 91 samples were captured using hybridization probe capture method. Compared with the original amplicon method, the hybridization probe capture method can distinguish the alleles of DRB1 and DPB1 that cannot be determined in 13 samples. The allelic imbalance of DRB1, DPA1, and DQB1 loci in 6 samples was resolved. Three samples were found to have missed detection of alleles at the DQA1 and DQB1 loci. [Conclusion] The performance indicators of hybridization probe capture and amplicon performance confirmation meet the requirements of clinical detection of HLA genotyping, which provides an experimental method and basis for clinical application.

ObjectiveTo explore the molecular mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer (NSCLC) by inducing ferroptosis via poly(rC)-binding protein 1 (PCBP1). MethodsThe serum containing Buzhong Yiqitang was prepared and cisplatin-resistant human non-small cell lung cancer (NSCLC) cells (A549/DDP) were cultured and randomly grouped as follows: Blank (10% blank serum), model (10% blank serum+20 mg·L-1 cisplatin), Buzhong Yiqitang (10% serum containing Buzhong Yiqitang+20 mg·L-1 cisplatin), Fe-1 (10% blank serum+20 mg·L-1 cisplatin+5 μmol·L-1 Fe-1), and Buzhong Yiqitang+Fe-1 (10% serum containing Buzhong Yiqitang+20 mg·L-1 cisplatin+5 μmol·L-1 Fe-1). Firstly, PCR Array was used to screen ferroptosis-related genes regulated by Buzhong Yiqitang, and PCBP1 was identified as the target for studying the attenuation of cisplatin resistance by Buzhong Yiqitang. Subsequently, the median inhibitory concentration (IC50) of cisplatin in each group was determined by the cell counting kit-8 (CCK-8) method and the resistance index (RI) was calculated. The ultrastructure of A549/DDP cells in each group was observed by transmission electron microscopy. The protein levels of PCBP1 and glutathione peroxidase 4 (GPX4) were determined by Western blot. The lipid reactive oxygen species (ROS) content in each group was determined by the C11-BODIRY 581/591 fluorescence probe. The ferrous ion assay kit was used to measure the ferrous ion content in each group. The malondialdehyde (MDA) assay kit was used to determine the MDA content in each group. ResultsCompared with model group, the IC50 of cisplatin and the RI of A549/DDP cells decreased in the Buzhong Yiqitang group (P<0.05) but increased in the Fe-1 group (P<0.05). The IC50 of cisplatin and the RI of A549/DDP cells in the Buzhong Yiqitang+Fe-1 group were lower than those in the Fe-1 group (P<0.05). Compared with the model group, the Buzhong Yiqitang group showed obvious mitochondrial ferroptosis, while the mitochondrial damage became less obvious after Fe-1 treatment. Compared with that in the Fe-1 group, the mitochondrial ferroptosis was aggravated after the intervention with Buzhong Yiqitang. Compared with blank group, the model group showed down-regulated expression levels of PCBP1 and GPX4 (P<0.05) and increased content of lipid ROS, ferrous ions, and MDA (P<0.05) in A549/DDP cells. Compared with model group, the Buzhong Yiqitang group showed down-regulated expression levels of PCBP1 and GPX4 (P<0.05) and increased content of lipid ROS, ferrous ions, and MDA (P<0.05), while the Fe-1 group showed up-regulated expression levels of PCBP1 and GPX4 (P<0.05) and reduced content of lipid ROS, ferrous ions, and MDA (P<0.05). Compared with the Fe-1 group, the Buzhong Yiqitang+Fe-1 group showed down-regulated expression levels of PCBP1 and GPX4 and increased content of lipid ROS, ferrous ions, and MDA (P<0.05). ConclusionBuzhong Yiqitang attenuated cisplatin resistance in NSCLC by regulating PCBP1 to induce ferroptosis.

ObjectiveTo investigate the mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer by observing the effects of Buzhong Yiqitang on endoplasmic reticulum stress-related molecules in human lung adenocarcinoma cells (A549) and cisplatin-resistant cells in human lung adenocarcinoma cells (A549/DDP) via the nuclear factor E2-related factor 2(Nrf2)/reactive oxygen species(ROS) pathway. MethodsThe serum containing Buzhong Yiqitang was prepared and A549 cells and A549/DDP cells were cultured. The cells were randomized into groups A (A549 cells+blank serum), B (A549 cells+20 mg·L-1 cisplatin+blank serum), C (A549 cells+20 mg·L-1 cisplatin+10% Buzhong Yiqitang-containing serum), D (A549/DDP cells+blank serum), E (A549/DDP cells+20 mg·L-1 cisplatin+blank serum), and F (A549/DDP cells+20 mg·L-1 cisplatin+10% Buzhong Yiqitang-containing serum). The cell counting kit-8 (CCK-8) method was used to detect the half maximal inhibitory concentration (IC50) of cisplatin. The protein levels of Nrf2 and p-Nrf2 were determined by Western blotting. The DCFH-DA fluorescent probe was used to measure the content of reactive oxygen species (ROS) in each group. The protein levels of glucose-regulated protein 78 (GRP78), activated transcription factor 6 (ATF6), and C/EBP-homologous protein (CHOP) were determined by Western blot. ResultsCompared with group B, group C showed a reduction in IC50 of cisplatin (P<0.05), which held true in group E compared with group F (P<0.05). Moreover, the IC50 of cisplatin to A549/DDP cells was higher than that to A549 cells before and after Buzhong Yiqitang intervention (P<0.05). Compared with group A, group B showed up-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05). Compared with group B, group C showed down-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05). Compared with group D, group E showed up-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05), which, however, were significantly down-regulated in group F (P<0.05). The ROS content and the protein levels of GRP78, ATF6, and CHOP followed a descending trend of group C > group B > group A in A549 cells and group F > group E > group D in A549/DDP cells (P<0.05). Moreover, the ROS content and the protein levels of GRP78, ATF6, and CHOP in A549 cells were higher than those in A549/DDP cells before and after Buzhong Yiqitang intervention (P<0.05). ConclusionBuzhong Yiqitang may regulate endoplasmic reticulum stress via the Nrf2/ROS pathway to attenuate cisplatin resistance in non-small cell lung cancer.
