ABSTRACT

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease, due to a combination of factors, is complex and has not yet been elucidated. Among them, intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells, autophagy regulates intestinal mucosal immunity, inflammation, oxidative stress, and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier, exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations, glucocorticoids, and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect, and the short-term efficacy is definite, but the long-term application is easy to be accompanied by more adverse reactions. Moreover, some drugs are expensive, bringing great physical and mental pain and economic burden to patients. Therefore, it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years, a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function, thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa, inflammation, oxidative stress, and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC, providing a new measure for the prevention and treatment of UC. However, there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore, based on the current research on UC, autophagy process, and Chinese medicine treatment, this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.

ABSTRACT

Ulcerative colitis (UC) is a chronic, non-specific inflammatory bowel disease. The pathogenesis of this disease is complex and is attributed to multiple factors. Intestinal mucosal barrier damage is the basic pathological change of UC, and intestinal flora disorder is one of the important characteristics of UC. Intestinal flora plays a key role in the pathological process of UC by regulating intestinal mucosal immunity and inflammatory response to repair the damaged intestinal mucosal barrier. At present, western medicine has the advantages of rapid action onset and significant short-term efficacy, but the curative effect of long-term use is not good, accompanied by many adverse reactions, causing great physical and mental pain to patients. Therefore, it is urgent to explore new treatment methods with definite long-term efficacy and mild adverse reactions. A large number of studies have shown that Chinese medicine can regulate intestinal flora through multiple targets in an all-around way, restore the homeostasis of the flora, and repair the damaged intestinal mucosal barrier, thereby inhibiting the progression of UC. Numerous studies have shown that the active components, monomers, and compounds of Chinese medicine can effectively antagonize UC by regulating the intestinal flora to improve the intestinal mucosal immunity, reduce the inflammatory response of the intestinal mucosa, and restore the normal physiological function of the intestinal mucosal barrier, providing a new strategy for UC prevention and treatment. Although there are some studies of the regulation of intestinal flora by Chinese medicine to prevent and treat UC, those studies have the shortcomings of systematic and comprehensive inadequacy. Therefore, based on the research status of UC, intestinal flora, and Chinese medicine treatment, this study reviewed the relationship between intestinal flora and UC and clarified the key role of intestinal flora in the occurrence and development of UC. At the same time, this paper comprehensively summarized the Chinese medicine that targeted the regulation of intestinal flora for the treatment of UC in the past five years to provide new strategies and ideas for UC treatment.

ABSTRACT

Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise, and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa, causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue, which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B (NF-κB) signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation, autophagy, apoptosis, and inflammatory response of esophageal epithelial cells and tumor cells, accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently, there is no specific treatment for reflux esophagitis and esophageal cancer, and large side effects often appear. Therefore, finding a promising and safe drug remains a top priority. In recent years, traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway, and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer, but there is a lack of comprehensive and systematic elaboration. Therefore, this paper summarized the relevant studies in recent years, analyzed the relationship among NF-κB signaling pathway, reflux esophagitis, esophageal cancer, and transformation from inflammation to cancer, and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer, so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.

ABSTRACT

Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths worldwide, with increasing incidence and mortality rates. The disease often develops covertly and lacks specific symptoms in its early stages, leading to late-stage diagnoses in most patients. It has become a prominent research topic in the field of digestive system tumors. The exact mechanisms underlying CRC are not yet clear and involve factors such as genetics, gene mutations, inflammatory responses, and aberrant activation of tumor-related signaling pathways. Nuclear factor-kappa B (NF-κB) is a crucial transcription factor that participates in various biological processes, including inflammatory responses, immune responses, cell proliferation, and apoptosis. Research suggests that NF-κB, serving as a molecular link between inflammation and cancer, is highly expressed in CRC. It promotes the occurrence and development of CRC by regulating the activity of target genes such as cell pro-inflammatory factors, chemokines, angiogenic factors, metastasis factors, and anti-apoptotic proteins. Currently, common treatments for CRC include surgery, radiation therapy, and chemotherapy drugs like 5-fluorouracil. However, these treatments have limitations such as significant adverse reactions, high metastasis rates, and the development of drug resistance. Therefore, the search for effective, low-adverse-reaction drugs to replace or supplement current treatments is essential. In recent years, traditional Chinese medicine (TCM) has shown some effectiveness in preventing and treating CRC. TCM has been found to inhibit the growth of CRC cells by modulating the NF-κB signaling pathway, playing a positive role in the occurrence and progression of CRC. Based on the asthenia in origin and sthenia in superficiality and deficiency-excess in complexity in CRC, this article summarized and analyzed the mechanisms and effects of TCM interventions targeting the NF-κB signaling pathway in CRC, and reviewed advances of 10 Chinese medicinal compound formulas and 37 Chinese medicinal monomer components of different types, including flavonoids, phenols, alkaloids, glycosides, and terpenoids with the effects of dispelling pathogenic factors, reinforcing healthy qi, and removing toxins in the prevention and treatment of CRC by targeting the NF-κB pathway. It is found that Chinese medicine can inhibit CRC cell proliferation, invasion, metastasis, angiogenesis, and inflammation by modulating the NF-κB signaling pathway, induce cell apoptosis, restore drug and radiation sensitivity, and counteract CRC. This article is expected to provide insights and references for the in-depth exploration and treatment of CRC mechanisms.

ABSTRACT

Ulcerative colitis (UC), a disease that affects the colon or rectum, is characterized by long-term recurrent inflammation and eventually leads to ulcers in the inner wall of the intestine. The disease has a high incidence and is difficult to be cured, which causes severe physical and mental discomfort and economic burden to the patients. Therefore, it is urgent to develop new therapies with high cure rate and low side effect. The pathological mechanism of UC is complex and involves multiple factors. The intestinal mucosal barrier damage is the main pathological basis of UC, which is a hot topic and a new research direction. Intestinal tight junction (TJ), as the structural basis of the intestinal mucosal mechanical barrier, can actively regulate mucosal function and play a key role in the pathogenesis of UC. Traditional Chinese medicine (TCM) can regulate TJ protein via multiple pathways and multiple targets, repair the intestinal mucosal barrier, and thus block the progression of UC. Studies have demonstrated that Chinese herbal medicines and their components, Chinese medicine compound prescriptions, and Chinese medicine preparations can treat UC by regulating TJ protein to maintain the function and reduce the permeability of intestinal epithelium, providing a new therapeutic strategy for UC. Although TCM has unique advantages that western medicine cannot replace by mediating TJ protein expression in UC, a comprehensive review of this field remains to be carried out. Focusing on the status of UC and TCM syndrome differentiation and treatment, we retrieved relevant articles with ''ulcerative colitis'', ''tight junction'', and ''Chinese medicine'' as the keywords, and summarized the relationship of TJ and its key target proteins with UC to clarify the critical role of TJ in UC pathophysiology. Furthermore, we summarized the Chinese medicines regulating TJ in the treatment of UC in recent years, aiming to provide a theoretical basis for the development of drugs for this disease.

ABSTRACT

Objective:To explore the possible mechanism of Bupiwei Xieyinhuo Shengyang Prescription on gastroesophageal reflux disease (GERD) based on network pharmacology and molecular docking technology.Methods:The main active components and target information of Bupiwei Xieyinhuo Shengyang Prescription were screened by TCMSP database, and targets were identified by GeneCards, OMIM, TTD and PharmGKB databases. The intersection of active ingredient components and disease targets was selected to construct PPI network by STRING. Cytoscape CytoNCA plug-in was used to extract core targets for analysis. GO function enrichment and KEGG pathway enrichment analysis were performed using Metascape. Cytoscape 3.7.2 was used to construct the "component-target-signal pathway" network, and Autodock was used to complete molecular docking verification. Animal experiments were further used for verification. SPF SD male rats were selected and GERD model was established by esophageal stent implantation. After 14 days of intervention, serum TNF-α and COX-2 levels of rats in each group were detected for verification.Results:A total of 215 effective compounds were screened from Bupiwei Xieyinhuo Shengyang Prescription. The main targets of GERD were TNF, IL6, CASP3, TP53 and PTGS2, which mainly focused on cancer pathway, AGE-RAGE signaling pathway, calcium signaling pathway and NF-κB signaling pathway. The results of molecular docking showed that the binding potential and activity of the key active components of Bupiwei Xieyinhuo Shengyang Prescription and the core target were better. Compared with the model group, Bupiwei Xieyinhuo Shengyang Prescription could reduce the serum expression levels of TNF-α and COX-2 ( P<0.01). Conclusions:By regulating TNF, IL6, CASP3, TP53, PTGS2 and other core targets, Bupiwei Xieyinhuo Shengyang Prescription can regulate NF-κB signaling pathway, calcium signaling pathway and other signaling pathways to play a role in the treatment of GERD.

ABSTRACT

Ulcerative colitis (UC) mainly occurs in the colon and rectum, with complex pathological mechanism. The occurrence of ulcerative colitis is associated with the uncontrollable inflammatory response of the intestine. The Western medicine therapy of UC mainly uses glucocorticoids and immunosuppressants to reduce intestinal inflammation. While blocking the progress of UC to a certain extent, it causes severe adverse reactions. More and more studies have confirmed that traditional Chinese medicine (TCM) has obvious advantages in the prevention and treatment of UC and can significantly reduce the recurrence of the disease. Pyroptosis, a novel form of cell death, can destroy cell structure, release intracellular pro-inflammatory substances, and mediate intestinal immune response in UC. TCM can promote pyroptosis (removing excess) or inhibit pyroptosis (replenishing deficiency), which is consistent with the regulation of Yin and Yang. TCM plays a role in the treatment of UC mainly by inhibiting pyroptosis (replenishing deficiency) and reducing intestinal immune response. In recent years, a large number of studies have been carried out to decipher the mechanism of TCM in the treatment of UC via NOD-like receptor protein domain 3 (NLRP3)-mediated pyroptosis pathway. The results have demonstrated that NLRP3 pathway is the key target of TCM in the treatment of UC. However, a comprehensive summary remains to be carried out on the inhibition of NLRP3-mediated pyroptosis pathway by TCM in the treatment of UC. Therefore, we retrieved the articles in this field in recent years with the keywords "pyroptosis", "NLRP3", "ulcerative colitis", and "Chinese medicine". The Chinese medicines regulating NLRP3 pathway mainly have the functions of clearing heat and drying dampness, harmonizing Qi and blood, moving Qi and dredging fu-organs, and invigorating spleen and removing dampness. The findings can help researchers to fully understand the mechanism of TCM in the treatment of UC via the NLRP3 pathway and provide a theoretical basis for the treatment of UC and further drug development.

ABSTRACT

Gastric cancer (GC) is a digestive tract tumor that occurs in the epithelial tissues of the gastric mucosa, seriously affecting the life and health of patients, and its mortality rate ranks the third among malignancies. Although medical technology has made great progress in recent years, the progression of GC still cannot be effectively controlled by surgery, chemotherapy, and targeted therapy. The pathogenesis of GC is extremely complex and is closely related to the tumor microenvironment, chronic inflammation, and immune escape, among which the reduction of tumor cell apoptosis is one of the important mechanisms for the occurrence and development of GC. Apoptosis refers to the process of spontaneous termination of cell life caused by genes under specific physiological or pathological conditions, which is of great significance for maintaining the stability of the internal environment. Researchers have found that in the GC state, mitochondrial endogenous apoptosis, endoplasmic reticulum stress, external death receptors, and other apoptosis pathways are regulated by multiple signaling pathways and genes, which together lead to the decline of GC cell apoptosis rate and thus promote the progression of GC. Chinese medicine is advantageous and characterized by multiple components, multiple targets, synergistic effect, and few adverse reactions. A large number of studies have shown that polysaccharide components, as effective components of Chinese medicine, have biological activities such as cancer inhibition, blood sugar control, anti-inflammation, antioxidant damage, and anti-virus, and can effectively inhibit the deterioration of GC by inducing cell apoptosis, gradually becoming a hot spot in GC drug research and development. However, systematic reviews on the apoptosis of GC induced by Chinese medicine polysaccharides are rarely reported. Therefore, this paper analyzed and summarized the studies of Chinese medicine polysaccharides in promoting apoptosis and interfering with GC, in order to provide a theoretical basis for the basic research, new drug development, and clinical application of Chinese medicine polysaccharides in the intervention of GC.

ABSTRACT

Ulcerative colitis (UC) is a clinical chronic intestinal disease, and the damage of the intestinal epithelial mucus barrier is an important pathological mechanism of UC. Mucin 2 (MUC2) is a major component of the intestinal mucus barrier, and goblet cells are the “main force” of MUC2 secretion, maintaining and renewing the intestinal mucus layer to ensure its integrity. Therefore, repairing the intestinal mucus barrier by promoting the synthesis of MUC2 by goblet cells is an important strategy for the treatment of UC. Traditional Chinese medicine scholars believe that there is an inherent layer of “lipid membrane” or “fat paste” in the intestine, and pathological factors such as moisture and heat lead to the thinning of this structure, which is the fundamental pathogenesis of “diarrhea” and “intestinal dysentery”. It coincides with the damage of intestinal mucus barrier leading to UC in modern medicine. Based on this, this paper summarized the mechanism of Chinese herbal compounds or Chinese herbal active components in regulating intestinal mucus barrier to interfere with UC. It was found that Chinese herbal compounds such as Huanglian jiedu decoction, Shaoyao decoction and Compound Kusen decoction, as well as Chinese herbal active ingredients such as volatile oil of Atractylodes lancea, paeoniflorin and papaya triterpenes could promote the synthesis and secretion function of goblet cells, and achieve the purpose of “thickening intestine”, thus relieving UC symptoms.

ABSTRACT

Colorectal cancer (CRC), a malignant tumor of the digestive system, originates from the colorectal mucosa epithelium and is usually asymptomatic until it progresses to an advanced stage. With high incidence around the globe and the increasingly younger patients, this disease poses a serious threat to the health and lives of the patients. Although the pathogenesis of this disease is not fully understood, it is generally believed that it is associated with autophagy, apoptosis, and inflammation. Autophagy and apoptosis as two types of programmed cell death are subject to complex interactive regulation, and the imbalance between them is closely related to the occurrence, development, and prognosis of a variety of diseases. Studies have shown that autophagy-apoptosis balance plays a key role in CRC. On the one hand, autophagy and apoptosis coordinate with each other to inhibit CRC cell growth. On the other hand, autophagy can antagonize apoptosis to promote CRC cell growth. In clinical practice, surgery is often combined with radiotherapy and chemotherapy to treat CRC, which can control the progression of CRC to a certain extent but has serious adverse effects and poor long-term results. In recent years, traditional Chinese medicine (TCM) has been proved to be effective in the treatment of CRC. Studies have shown that numerous herbal active components can promote CRC cell death by regulating the autophagy-apoptosis balance, thereby blocking the progression of this disease. The process of autophagy-apoptosis balance in regulating cell activities has similar theoretical connotations with the Yin and Yang theory of TCM. Applying TCM in regulating autophagy-apoptosis balance at various stages of CRC has become a frontier, while the comprehensive elaboration remains to be conducted. By reviewing the relevant studies in recent years, this paper introduces the correlation between the Yin and Yang theory and the autophagy-apoptosis balance, the role of autophagy-apoptosis balance in CRC, and the research progress in the application of 27 Chinese herbal active components such as flavonoids, terpenoids, glycosides, and phenols capable of regulating autophagy-apoptosis balance in the treatment of CRC. The active components in Chinese medicines can recover the autophagy-apoptosis balance in CRC by acting on microtuble-associated protein 1 light chain 3(LC3), Beclin-1, and B-cell lymphoma-2(Bcl-2)to regulate multiple signaling pathways such as protein kinase B(Akt)/mammalian target of rapamycin(mTOR)and reavtive oxygen species(ROS)/ c-Jun N-terminal kinase(JNK), thus balancing Yin and Yang. This review aims to provide a reference for the treatment of CRC and the development of new drugs.

ABSTRACT

Ulcerative colitis (UC) is a disease that affects the mucosal and submucosal layers of the colon and is characterized by inflammation of the intestinal mucosa. The incidence of UC is increasing year by year, and it is complex and refractory, severely impacting the physical and mental health of patients. The pathological mechanism of this disease is complex, with immune responses and uncontrollable inflammatory reactions in the intestine being important physiopathologic mechanisms. Toll-like receptor 4 (TLR4), as a transmembrane signaling receptor, plays a key role in mediating immune responses and inflammatory reactions in the development of UC. Currently, the treatment of UC mainly relies on salicylic acids, glucocorticoids, and other agents to reduce intestinal inflammation. While these drugs can partially inhibit the progression of the disease, they often come with significant adverse effects and the potential for relapse upon discontinuation. Traditional Chinese medicine (TCM) offers multiple pathways, effects, and targets for regulating the TLR4 pathway, suppressing inflammatory responses, and effectively intervening in the progression of UC. This approach has become a hot topic in the prevention and treatment of UC. Numerous studies have shown that TCM treatment of UC has unique advantages. TCM can enhance immune defenses, suppress inflammatory responses, promote intestinal mucosal healing, and maintain the balance of the intestinal microbiota by regulating the TLR4 signaling pathway, thereby effectively treating UC, with substantial progress achieved. However, there is currently a lack of comprehensive reviews on the role of TCM in regulating the TLR4 signaling pathway for the treatment of UC. Therefore, this article systematically summarized the relationship between the TLR4 signaling pathway and UC, as well as the role of TCM in this context, by reviewing relevant literature from recent years, aiming to provide new insights into the potential treatment and new drug development for UC.

ABSTRACT

Pancreatic cancer is one of the most destructive malignant tumors; the pathogenesis of this disease is complex and is closely related to genetic susceptibility, chronic pancreatitis, and gene mutations in signaling pathways. The phosphoinositide 3- kinase (PI3K)/protein kinase B (Akt) signaling pathway is a classical cancer signaling pathway that is aberrantly activated in pancreatic cancer cells. In recent years, it has been found that traditional Chinese medicine (TCM) monomers show special activity in the treatment of pancreatic cancer and can be potential drug for the treatment of pancreatic cancer. Based on PI3K/Akt signaling pathway, this paper summarizes the mechanism of TCM monomer intervening in pancreatic cancer and finds that TCM monomer of alkaloids (sinomenine, dictamnine, dauricine, etc.), terpenoids (saikosaponin A, linderalactone, isoalantolactone, etc.), phenols (6-gingerol, curcumin, pterostilbene, etc.), flavonoids (fisetin, kaempferol, quercetin, etc.) and quinones (β-hydroxyisovaleryl shikonin, rhein, lucidone, etc.) can inhibit the proliferation, invasion and migration of pancreatic cancer cells, regulate autophagy and apoptosis, and then inhibit the pathological process of pancreatic cancer by inhibiting PI3K/Akt signaling pathway.

ABSTRACT

OBJECTIVE@#To analyze the characteristics of gene mutation and overexpression in newly diagnosed multiple myeloma (NDMM) patients.@*METHODS@#Bone marrow cells from 208 NDMM patients were collected and analyzed. The gene mutation of 28 genes and overexpression of 6 genes was detected by DNA sequencing. Chromosome structure abnormalities were detected by fluorescence in situ hybridization (FISH).@*RESULTS@#Gene mutations were detected in 61 (29.33%) NDMM patients. Some mutations occurred in 5 or more cases, such as NRAS, PRDM1, FAM46C, MYC, CCND1, LTB, DIS3, KRAS, and CRBN. Overexpression of six genes (CCND1, CCND3, BCL-2, CCND2, FGFR3, and MYC) were detected in 83 (39.9%) patients, and cell cycle regulation gene was the most common. Single nucleotide polymorphisms (SNP) changes were detected in 169 (81.25%) patients, the TP53 P72R gene SNP (70.17%) was the most common. Abnormality in chromosome structure was correlated to gene overexpression. Compared to the patients with normal chromosome structure, patients with 14q32 deletion showed higher proportion of CCND1 overexpression. Similarly, patients with 13q14 deletion showed higher proportion of FGFR3 overexpression, whereas patients with 1q21 amplification showed higher proportion of CCND2, BCL-2 and FGFR3 overexpression.@*CONCLUSION@#There are multiple gene mutations and overexpression in NDMM. However, there is no dominated single mutation or overexpression of genes. The most common gene mutations are those in the RAS/MAPK pathway and the genes of cyclin family CCND are overexpression.

ABSTRACT

OBJECTIVE@#To analyze the molecular pathogenesis by analysis of phenotype and gene mutation in families with hereditary coagulation factor V (FⅤ) defect caused by complex heterozygous mutation.@*METHODS@#Plasma pro-thrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), FⅤ procoagulant activity (FⅤ∶C), FⅤ antigen (FⅤ∶Ag), and other related coagulation indexes were detected in the proband and his family members (3 generations 10 people). Using DNA direct sequencing to analyze all exons, flanks, 5' and 3' untranslated regions of F5 genes and the corresponding mutation site regions of family members, the mutation site was confirmed by reverse sequencing.The conservation of mutant amino acids was analyzed by ClustalX-2.1-win software. The PROVEAN and MutationTaster online bioinformatics software were used to predict the effect of mutation on protein function. Protein model and amino acid interaction at mutation sites was analyzed by Swiss-pdbviewer software.@*RESULTS@#The PT and APTT of the proband were significantly prolonged compared with healthy controls (34.2 vs 13.2 s and 119.3 vs 36.0 s), while FⅤ∶C and FⅤ∶Ag extremely reduced (3% and 6%). The PT and APTT of the second-born, the third son, daughter, and grandson of the proband were slightly prolonged, and the FⅤ∶C and FⅤ∶Ag decreased to varying degrees. The related coagulant parameters of other family members were within normal range. Genetic analysis revealed that the proband had a c.911G>A heterozygous missense mutation on the exon 6 lead to p.Gly276Glu, and a c.5343C>G heterozygous missense mutation on the exon 16 lead to p.Ser1781Arg of the proband. The second-born, the third son, and grandson of the proband carry p.Gly276Glu heterozygotes, and the daughter carries p.Ser1781Arg heterozygotes, while the other family members were wild-type. The results of conservative analysis indicated that p.Gly276 and p.Ser1781 were highly conserved in homologous species. The two bioinformatics software predicted the same results, PROVEAN (score -6.214 and -12.79) indicated that the compound heterozygous mutation was a harmful mutation; MutationTaster (score 0.976 and 0.999) suggested that these mutations might cause corresponding disease. p.Gly276Glu protein model analysis showed that, the Glu side chain was prolonged and the molecular weight became larger, which would increase the steric hindrance between it and the surrounding amino acids, affect the normal local folding of the FⅤ protein, and eventually lead to the decrease of protein activity and content. This paper can not provide analysis of the spatial structure of p.Ser1781Arg mutant protein because of the lack of X ray 3 D structure file of FⅤ exon 16.@*CONCLUSION@#The new compound heterozygous mutations (p.Gly276Glu and p.Ser1781Arg) identified in this study are the main reasons for the decrease in the FⅤ level of the family, among which p.Ser1781Arg is rarely reported at home and abroad.

ABSTRACT

OBJECTIVE@#To investigate the expression of CD123 in patients with acute myeloid leukemia (AML) and its relationship between clinical features, concomitant fusion gene or gene mutation, efficacy and prognosis.@*METHODS@#365 patients with newly diagnosed AML (except M3) treated in the First Affiliated Hospital of Zhengzhou University were enrolled and retrospective analysis, and multi-parameter flow cytometry was performed to detect the expression of CD123 in myeloid leukemia cell population. CD123≥20% was defined as positive. Clinical features, concomitant fusion gene or gene mutation, efficacy and prognosis of CD123@*RESULTS@#The positive rate of CD123 in 365 newly diagnosed AML patients was 38.9%. Compared with the CD123@*CONCLUSION@#CD123 positive indicates that AML patients have higher tumor burden and are more difficult to reach remission. It is an independent risk factor for OS and EFS in patients with normal karyotype and intermediate risk, which is important to evaluate the prognosis of patients with AML without specific prognostic marker.

ABSTRACT

BACKGROUND@#Due to the different treatments for low-volume metastatic prostate cancer (PCa) as well as high-volume ones, evaluation of bone metastatic status is clinically significant. In this study, we evaluated the correlation between pre-treatment plasma fibrinogen and the burden of bone metastasis in newly diagnosed PCa patients.@*METHODS@#A single-center retrospective analysis, focusing on prostate biopsies of newly diagnosed PCa patients, was performed. A total of 261 patients were enrolled in this study in a 4-year period. All subjects were submitted to single-photon emission computerized tomography-computed tomography to confirm the status of bone metastasis and, if present, the number of metastatic lesions would then be calculated. Clinical information such as age, prostate-specific antigen (PSA), fibrinogen, clinical T stage, and Gleason score were collected. Patients were divided into three groups: (i) a non-metastatic group, (ii) a high volume disease (HVD) group (>3 metastases with at least one lesion outside the spine), and (iii) a low volume disease (LVD) group (metastatic patients excluding HVD ones). The main statistical methods included non-parametric Mann-Whitney test, Spearman correlation, receiver operating characteristic (ROC) curves, and logistic regression.@*RESULTS@#Fibrinogen positively correlated with Gleason score (r = 0.180, P = 0.003), PSA levels (r = 0.216, P 7 (86.8%). Both univariate (odds ratio [OR] = 2.16, 95% confidential interval [CI]: 1.536-3.038, P < 0.001) and multivariate (OR = 1.726, 95% CI: 1.206-2.472, P = 0.003) logistic regressions showed that fibrinogen was independently associated with HVD. The ROC curve suggested that fibrinogen acts as a predictor of HVD patients, yielding a cut-off of 3.08 g/L, with a sensitivity of 0.684 and a specificity of 0.760 (area under the curve = 0.739, 95% CI: 0.644-0.833, P < 0.001).@*CONCLUSIONS@#Pre-treatment plasma fibrinogen is positively associated with bone metastatic burden in PCa patients. Our results indicate that fibrinogen might be a potential predictor of HVD.

ABSTRACT

OBJECTIVE@#To investigate the clinical features, accompanying gene mutation characteristics and prognostic factors of adult patients with acute myeloid leukemia with mutated NPM1 (NPM1AML).@*METHODS@#Seventy-three patients with newly diagnosed adult NPM1AML were selected. The mutations of 22 genes were detected by second generation sequencing and 43 fusion genes of AML were detected by real-time fluorescent quantitative PCR. The Kaplan-Meier survival curve and Cox multivariate regression analysis were used to study the prognostic factors.@*RESULTS@#A total of 74 NPM1 site mutations were detected in 73 patients with NPM1AML. The incidence rates were 92.0% L287fs, 2.7% Q289fs and W288fs, 1.4% L258fs and Q289H, among which 1 patient had 2 NPM1 mutations; the different mutation sites had no effect on the prognosis of NPM1AML. The median value of NPM1 variant allele frequency (VAF) was 35.4% (1.8%-56.6%). Based on the uppermost quartile of 38.4%, the patients were classified as NPM1 VAF>38.4% (NPM1AML) and NPM1 VAF≤38.4% (NPM1AML). Compared with NPM1AML, the early mortality rate was statistically significantly higher (33.3% vs 7.3%, P38.4% was an independent prognostic factor for EFS (HR=3.1, 95% CI 1.6-6.4, P<0.01) and OS (HR=3.0, 95% CI 1.4-6.2, P<0.01).@*CONCLUSION@#The NPM1 gene mutation in AML patients often is accompanied by other gene mutations, while the coexistence of fusion genes is rare; high NPM1 mutant allele burden is an independent prognostic factor for adult AML patients with mutated NPM1.
