ABSTRACT

Solute carriers (SLCs) constitute the largest superfamily of membrane transporter proteins. These transporters, present in various SLC families, play a vital role in energy metabolism by facilitating the transport of diverse substances, including glucose, fatty acids, amino acids, nucleotides, and ions. They actively participate in the regulation of glucose metabolism at various steps, such as glucose uptake (e.g., SLC2A4/GLUT4), glucose reabsorption (e.g., SLC5A2/SGLT2), thermogenesis (e.g., SLC25A7/UCP-1), and ATP production (e.g., SLC25A4/ANT1 and SLC25A5/ANT2). The activities of these transporters contribute to the pathogenesis of type 2 diabetes mellitus (T2DM). Notably, SLC5A2 has emerged as a valid drug target for T2DM due to its role in renal glucose reabsorption, leading to groundbreaking advancements in diabetes drug discovery. Alongside SLC5A2, multiple families of SLC transporters involved in the regulation of glucose homeostasis hold potential applications for T2DM therapy. SLCs also impact drug metabolism of diabetic medicines through gene polymorphisms, such as rosiglitazone (SLCO1B1/OATP1B1) and metformin (SLC22A1-3/OCT1-3 and SLC47A1, 2/MATE1, 2). By consolidating insights into the biological activities and clinical relevance of SLC transporters in T2DM, this review offers a comprehensive update on their roles in controlling glucose metabolism as potential drug targets.

ABSTRACT

Objective@#To explore the intervention effect of 12 week spinal health exercise on adolescents high and low shoulders, in order to provide empirical evidence for exploring simple and feasible measures to intervene.@*Methods@#In February 2023, 60 high and low shoulder students from a vocational high school in a certain county of Luzhou City were randomly selected as the research subjects by convenient sampling method. Paired sampling was used to randomly divide participants into an intervention group and a control group with 30 students each group. The intervention group received spinal health gymnastics intervention during 12 weeks of morning exercises and large break exercises for twice a day, with two groups each time; the control group maintained their previous morning exercises and large break exercises. A follow up study was conducted on the height difference between the left and right shoulder peaks of the intervention group and the control group students before intervention, after 12 weeks intervention, at 4 weeks post intervention. The t-test was used to analyze the changes in shoulder peak height difference between the intervention group and the control group.@*Results@#Before intervention, there was no statistically significant difference in the height of the left and right shoulder peaks between the intervention group [(2.50±1.19)cm] and the control group [(2.49±1.20)cm] adolescents ( t=0.05, P > 0.05). After 12 weeks of intervention, the difference in shoulder height between the left and right sides of adolescents in the intervention group decreased, compared to that before intervention [(1.43±1.15, 2.50±1.19)cm], while the control group increased compared to that before intervention [(2.58±1.19, 2.49±1.20) cm], and the differences were both statistically significant ( t= -78.17 , 20.15, P <0.05). At 4 weeks post intervention, there was no statistically significant difference in the height of the left and right shoulder peaks between the intervention group [(1.44±1.15)cm] and the control group [(2.59±1.18)cm] compared to 12 weeks after the intervention ( t=1.80, 1.05, P >0.05). The intervention group [(2.49±1.26, 2.52±1.16) (1.43±1.21, 1.44±1.13) (1.44±1.21, 1.45±1.14)cm] and the control group [(2.45±1.24, 2.52±1.20) (2.55±1.24, 2.61±1.18) (2.55±1.22, 2.62±1.18)cm] showed no statistically significant difference in the height of the left and right shoulder peaks between males and females before intervention, after 12 weeks of intervention, and after stopping intervention for 4 weeks ( t =-0.08, -0.03, -0.02; -0.15, -0.12, -0.15, P >0.05).@*Conclusions@#Spinal health gymnastics has a good effect on correcting high and low shoulders in adolescents. Spinal health gymnastics should be promoted on campus to promote adolescent posture health.

ABSTRACT

Pyroptosis is the programmed death of cells accompanied by an inflammatory response and is widely involved in the development of a variety of diseases, such as infectious diseases, cardiovascular diseases, and neurodegeneration. It has been shown that cellular scorching is involved in the pathogenesis of pulmonary arterial hypertension ( PAH) in cardiovascular diseases. Patients with PAH have perivascular inflammatory infiltrates in lungs, pulmonary vasculopathy exists in an extremely inflam-matory microenvironment, and pro-inflammatory factors in cellular scorching drive pulmonary vascular remodelling in PAH patients. This article reviews the role of cellular scorch in the pathogenesis of PAH and the related research on drugs for the treatment of PAH, with the aim of providing new ideas for clinical treatment of PAH.

ABSTRACT

ObjectiveTo explore the feasibility and rationality of applying relevant diagnostic and treatment programmes from textbooks as evidence in traditional Chinese medicine (TCM) diagnosis and treatment guidelines, using allergic rhinitis as an example. MethodsTextbooks published from October 1949 to December 2022, as well as TCM diagnosis and treatment guidelines published until December 2022 on allergic rhinitis were searched, and the contents of diagnosis and treatment related to allergic rhinitis were extracted. The similarities and differences between textbooks in different periods, between textbooks in different versions, and between textbooks and guidelines were compared and analyzed. ResultsA total of 12 national planning textbooks on TCM otolaryngology and 4 Chinese medicine diagnosis and treatment guidelines on allergic rhinitis from 1975 to 2021 were included. The evolution of diagnostic and treatment programmes was shown by the textbooks in different periods. Since 2003, syndrome of latent heat in lung channel has been added in the published textbook, and TCM featured therapies, such as nasal packing, intranasal spray were enriched, as well as the contents related to prevention and prognosis. The main syndromes included lung qi deficiency and cold, spleen qi deficiency, kidney yang deficiency, and latent heat in lung meridian. The most common recommended prescriptions were Wenfei Zhiliu Pill (温肺止流丹), Yupingfeng Powder (玉屏风散) and Cangerzi Powder (苍耳子散); Buzhong Yiqi Decoction (补中益气汤), Shenling Baizhu Powder (参苓白术散); Shenqi Pill (肾气丸) or Zhenwu Decoction (真武汤); Xinyi Qingfei Decoction (辛夷清肺饮). A comparison of different versions of textbooks showed that the classification of syndromes was consistent, while the formulas were slightly different. The comparison between different versions of the current textbooks and the guidelines showed that the recommended prescriptions of the textbooks had more Cangerzi Powder, Xiaoqinglong Decoction (小青龙汤), Zhenwu Decoction, etc., while TCM featured therapies such as nose blowing, smelling, nasal plugging, nasal washing were enriched, and information on formula modification, prevention and adjustment, prognosis were also added, which can supplement the corresponding evidence for the guidelines. ConclusionTextbooks could serve as a strong supplement for the evidence-based development of TCM clinical guidelines. However, there is still a need for further research on the quality assessment system of textbook evidence to improve the credibility of its applicability of the guidelines evidence.

ABSTRACT

Objective To analyse the analgesic effect and possible mechanism of panax notoginseng saponin (PNS) on mouse models of chronic inflammatory pain caused by complete Freund’s adjuvant (CFA). Methods A total of 48 male C57BL/ 6J mice were divided randomly into four groups: normal saline control group (Ctrl), CFA group (CFA), CFA + PNS group (CFA+PNS), CFA + dexamethasone (DEX) group (CFA+DEX). Von Frey filaments were used to detect mechanical pain in mice. Immunohistochemistry was used to detect the number and morphological changes of glial fibrillary acidic protein (GFAP) positive astrocytes. Western blotting was used to detect the expressions of GFAP, nucleotide-binding and oligomerization domain(NOD)-like receptor thermal protein domain associated protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, interleukin (IL)-1β, and IL-18 in mice’s spinal cord segments in each group. Results Compared with the Ctrl group, mice in the CFA group showed a significant decrease in mechanical pain thresholds at day 1, day 3, day 5, day 7, and day 14. Additionally, there was a significant decrease in NLRP3, ASC, Caspase-1, IL-1β and IL-18 in the spinal cord of the mice. PNS intervention could relieve mechanical pain and down-regulate the expressions of NLRP3, ASC, Caspase-1, IL-1β and IL-18 in the spinal cord of mice, with no significant difference compared with the CFA+DEX group. CFA group mice had significantly more GFAP positive cells in their posterior horns than Ctrl group mice, as measured by immunohistochemistry; PNS intervention decreased the number of GFAP positive cells in the posterior horn of the spinal cord in model mice;DEX had no effect on the number of GFAP positive cells in the dorsal horn of spinal cord. According to Western blotting results, GFAP expression in the spinal cord of the CFA group was significantly more than that of the Ctrl group; PNS intervention significantly reduced GFAP expression in the spinal cord of CFA group mice;DEX had no effect on the expression of GFAP in the posterior horn of spinal cord. Conclusion PNS has a good alleviating effect on inflammatory pain, and its mechanism may be related to inhibition of astrocyte activation and NLRP3 inflammasome activation.

ABSTRACT

OBJECTIVE@#To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET).@*METHODS@#Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births.@*RESULTS@#Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05).@*CONCLUSIONS@#Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

ABSTRACT

BACKGROUND:Overactive osteoclasts disrupt bone homeostasis and play a bad role in the pathological mechanisms of related skeletal diseases,such as osteoporosis,fragility fractures,and osteoarthritis.Studies have confirmed that ellagic acid and ellagtannin have the potential to inhibit osteoclast differentiation.As their natural metabolites,urolithin A has antioxidant,anti-inflammatory,anti-proliferative and anti-cancer effects,but its effect on osteoclast differentiation and its underlying molecular mechanisms remain unclear. OBJECTIVE:To explore the effect of urolithin A on osteoclast differentiation induced by receptor activator for nuclear factor-κB ligand and its mechanism. METHODS:Mouse mononuclear macrophage leukemia cells(RAW264.7)that grew stably were cultured in vitro.Toxicity of urolithin A(0,0.1,0.5,1.5,2.5 μmol/L)to RAW264.7 cells were detected by cytotoxic MTS assay to screen out the safe concentration.Different concentrations of urolithin A were used again to intervene with receptor activator for nuclear factor-κB ligand-induced differentiation of RAW264.7 cells in vitro.Then,tartrate-resistant acid phosphatase staining and F-actin ring and nucleus staining were performed to observe its effect on the formation and function of osteoclasts.Finally,the expressions of urolithin A on upstream and downstream genes and proteins in the MAPK signaling pathway were observed by western blot and RT-qPCR assays. RESULTS AND CONCLUSION:Urolithin A inhibited osteoclast differentiation and F-actin ring formation in a concentration-dependent manner and 2.5 μmol/L had the strongest inhibitory effect.Urolithin A inhibited the mRNA expression of Nfatc1,Ctsk,Mmp9 and Atp6v0d2 and the protein synthesis of Nfatc1 and Ctsk,related to osteoclast formation and bone resorption.Urolithin A inhibited the activity of osteoclasts by downregulating the phosphorylation of p38 protein to inhibit the mitogen-activated protein kinase signaling pathway.

ABSTRACT

BACKGROUND:Conducting mental fatigue research in sports depends on appropriate mental fatigue induction tasks.However,the different types and time settings for the tasks in this field have interfered with the selection and determination of the appropriate task for mental fatigue research. OBJECTIVE:To compare the effects of three mental fatigue tasks and their commonly used time settings for mental fatigue induction. METHODS:In this randomized crossover study,16 male amateur soccer players performed four tasks of 60-minute duration with an interval≥48 hours in a randomized counter-balanced order:STROOP task(psychological cognition group),social media use in smartphone(electron exposure group),whole-body coordination task(exercise group)and emotionally neutral video watching as controls(control group).Before each task,the visual analogue scale(VAS)-motivation,VAS-mental fatigue,VAS-physical fatigue,and average heart rate were measured.Also,the VAS-mental fatigue,VAS-mental exertion,VAS-physical fatigue,and average heart rate were recorded every 15 minutes during the task.Repeated measures analysis of variance was mainly used for statistical analysis. RESULTS AND CONCLUSION:The baseline level of VAS-mental fatigue in the four groups were similar(P=0.806).(2)The VAS-mental fatigue of the psychological cognition group at 30,45 and 60 minutes was significantly higher than that of the other three groups(all P<0.05).The VAS-mental fatigue of psychological cognition,electron exposure,and exercise groups at 45 minutes were similar with that at 60 minutes(all P>0.05),but significantly higher than that of pretest,15 minutes and 30 minutes(all P<0.05).To conclude,the psychological cognition task is superior to the electron exposure and exercise tasks for mental fatigue induction and 45 minutes is the appropriate length of time to effectively induce mental fatigue.

ABSTRACT

Objective:To determine the predictive value of high-frequency ultrasonography for necrotizing enterocolitis (NEC) requiring surgical treatment in neonates.Methods:From January 2018 to December 2021, neonates diagnosed with NEC (Bell stage Ⅱ and above) in our hospital were retrospectively analyzed. The neonates were assigned into surgical group and non-surgical group according to the treatment. The following ultrasonography results were compared between the two groups: intestinal motility, gastrointestinal (GI) wall perfusion, pneumatosis intestinalis (PI), portal vein gas, peritoneal effusion translucency, depth of ascites fluid and GI wall thickness. Logistic regression was used to determine risk factors of surgical treatment for NEC. ROC curve was drawn to calculate the predictive value of combined and individual factors for NEC requiring surgical treatment.Results:A total of 40 neonates were enrolled, including 18 in the surgical group and 22 in the non-surgical group. No significant differences existed between the two groups in PI and depth of ascites fluid ( P>0.05). The surgical group had higher incidences of decreased intestinal motility, portal vein gas, reduced GI wall perfusion, poor peritoneal effusion translucency and thinner GI wall than the non-surgical group (all P<0.05). Logistic regression analysis showed that poor translucency of peritoneal effusion, thinning of GI wall, reduced GI wall perfusion and decreased intestinal motility were risk factors for surgical treatment of NEC. ROC curve showed that the cut-off value predicting surgical treatment based on GI wall thickness was 1.2 mm, with an area under the curve (AUC) of 0.746, sensitivity of 87.5% and specificity of 65.6%. The AUC of the combined factors predicting surgical treatment was 0.867, with sensitivity of 96.9% and specificity of 75.8%. Conclusions:Decreased intestinal motility and GI wall perfusion, thinning of GI wall and poor peritoneal effusion translucency on high-frequency ultrasonography have high predictive efficacy for the need of surgical treatment in the acute phase of NEC.

ABSTRACT

Objective To compare the prevention and control effects of binocular myopia after wearing orthokeratology lenses or glasses for correction in adolescents with low-to-moderate unilateral myopia.Methods The clinical data of 46 adolescents with unilateral myopia treated in First Affiliated Hospital of Army Medical University were retrospectively analyzed,the patients were divided into the orthokeratology lenses group and spectacles group according to the correction methods,with 23 cases in each group.The axial length(AL),changes in spherical diopter(SD)and anisometropia between the myopic eye and the control eye with orthokeratology lenses spectacles for unilateral myopia correction,and orthokeratology lenses for unilateral and binocular myopia were compared.Results There was no significant difference in baseline AL,SD or anisometropia between the two groups(P>0.05).One year after unilateral myopia correction,the increase of SD for the myopic eye in the orthokeratology lenses group was less than that in the spectacles group(P<0.05),and there was no significant difference in the AL elongation of myopic eyes between the two groups(P>0.05);the elongation of AL for the control eyes in the orthokeratology lenses group was more than that in the spectacles group;the increase of SD for the myopic eyes in the orthokeratology lens group was lower than that in the spectacles group(P<0.05),and there was no significant difference in the increase of SD for the control eyes between the two groups(P>0.05);the anisometropia of patients in the orthokeratology lenses group was less than that in the spectacles group(P<0.05).The biological parameters of the eyes before and after wearing orthokeratology lenses in the patients with monocular and binocular myopia in the orthokeratology lens group were compared,the elongation of AL for the myopic eyes with lens in one eye was less than that with lenses in both eyes(P<0.05),and the elongation of AL for the control eye was more than that with lenses in both eyes(P<0.05),the increases of SD in both myopic eyes and control eyes were more than those with lenses in both eyes(P<0.05),and the anisotropia was more than that with lenses in both eyes(P<0.05).Conclusion Orthokeratology lenses is better than spectacles in controlling the increase of myopia in low-to-moderate unilateral myopia,which can reduce anisometropia between eyes.However,the AL of the emmetropic eye increases rapidly during unilateral myopia correction by orthokeratology lenses,and the progression of binocular myopia can be significantly delayed after wearing orthokeratology lenses.

ABSTRACT

Objective:To investigate the value of a novel technique called visual transient elastography (ViTE) and liver steatosis analysis (LiSA) in assessing liver function injury in hepatitis B virus-related hepatocellular carcinoma (HBV-related HCC) patients after ablation therapy.Methods:A total of 129 HBV-related HCC patients in Harbin Medical University Cancer Hospital from January 2022 to August 2023 were retrospectively analyzed.ViTE and LiSA examinations were applied to record the liver stiffness E value and LiSA value before ablation. An albumin-bilirubin (ALBI) score was constructed using laboratory indicators. Spearman correlation analysis was used to assess the correlation between E value, LiSA value and ALBI score, body mass index (BMI). According to the change of ALBI grade in perioperative period, the patients could be divided into two groups: liver function unchanged group and liver function injury group. Univariate and multivariate statistical methods were used to analyze related factors affecting changes in liver function after ablation, followed by establishing a predictive model.Results:Spearman analysis showed a strong positive correlation between E value and ALBI score ( rs=0.686, P<0.001), and LiSA value was weakly positively correlated with BMI ( rs=0.338, P<0.001). There were no significant correlations between E value and BMI, LiSA value and ALBI score (all P>0.05). Univariate analysis showed that differences of age, BMI, ablation parameters, E value, and LiSA value in the two groups were statistically significant (all P<0.05). Multivariate analysis showed that E value, LiSA value, and ablation time were independent predictors of hepatic dysfunction after ablation (all P<0.05). AUC was 0.892 indicating high accuracy in the predictive model based on above indicators. Conclusions:Under the real-time ultrasound guidance, a non-invasive liver function injury prediction model based on ViTE and LiSA technology can offer personalized predictions for ablative perioperative changes in liver function among HBV-related HCC patients.

ABSTRACT

Objective@#Anxious depression is a prevalent characteristic observed in Asian psychiatric patients diagnosed with major depressive disorder (MDD). This study aims to investigate the prevalence and clinical presentation of anxious depression in Taiwanese individuals diagnosed with MDD. @*Methods@#We recruited psychiatric outpatients aged over 18 who had been diagnosed with MDD through clinical interviews. This recruitment took place at five hospitals located in northern Taiwan. We gathered baseline clinical and demographic information from the participants. Anxious depression was identified using a threshold of an anxiety/somatization factor score ≥7 on the 21-item Hamilton Rating Scale for Depression (HAM-D). @*Results@#In our study of 399 patients (84.21% female), 64.16% met the criteria for anxious depression. They tended to be older, married, less educated, with more children, and an older age of onset. Anxious depression patients had higher HAM-D and Clinical Global Impression–Severity scale score, more panic disorder (without agoraphobia), and exhibited symptoms like agitation, irritability, concentration difficulties, psychological and somatic anxiety, somatic complaints, hypochondriasis, weight loss, and increased insight. Surprisingly, their suicide rates did not significantly differ from non-anxious depression patients. This highlights the importance of recognizing and addressing these unique characteristics. @*Conclusion@#Our study findings unveiled that the prevalence of anxious depression among Taiwanese outpatients diagnosed with MDD was lower compared to inpatients but substantially higher than the reported rates in European countries and the United States. Furthermore, patients with anxious depression exhibited a greater occurrence of somatic symptoms.

ABSTRACT

Arrhythmia is an important disease among cardiovascular diseases. Malignant arrhythmias often occur clinically and are induced by abnormal ion channels, electrical activity disorders, myocardial fibrosis, inflammation, dysfunctional mitochondrial biogenesis, mitochondrial calcium overload, out-of-balance energy metabolism, oxidative stress, sympathetic hyperactivity, and other pathological cardiac remodeling, and they are the main causes of sudden cardiac death. In traditional Chinese medicine, arrhythmias are considered to be palpitations, which are commonly caused by deficiency of Qi and Yin. It is often manifested as a deficiency of the spleen and stomach, resulting in malfunction of the Qi mechanism, followed by a particularly severe decline in cardiac function. Shengmaisan is a representative formula for nourishing Qi and Yin, consisting of Ginseng Radix et Rhizoma, Ophiopogonis Radix, and Schisandrae Chinensis Fructus. In recent years, clinical studies have shown that Shengmaisan and its additions and subtractions are commonly used in the treatment of arrhythmias. In this article, the mechanisms of the active ingredients of Shengmaisan in the electrophysiology, biochemistry, structure, autonomic nervous system, and subcellular fraction of the heart are reviewed, and the multi-target, multi-system, and integrality of Shengmaisan in the treatment of arrhythmias of Qi and Yin deficiency are described. In addition, energy metabolism disorder is tightly juxtaposed with Qi and Yin deficiency syndrome. Mitochondria, as the center of myocardial energy metabolism, play a paramount role in cardiac remodeling, indicating that Shengmaisan will be a salient part of future research to ameliorate cardiac pathologic remodeling through energy metabolism of mitochondria, so as to provide a theoretical basis for the clinical treatment of these arrhythmias.

ABSTRACT

Currently the main treatment of acute myeloid leukemia (AML) is chemotherapy combining hematopoietic stem cell transplantation. However, the unbearable side effect of chemotherapy and the high risk of life-threatening infections and disease relapse following hematopoietic stem cell transplantation restrict its application in clinical practice. Thus, there is an urgent need to develop alternative therapeutic tactics with significant efficacy and attenuated adverse effects. Here, we revealed that umbilical cord-derived mesenchymal stem cells (UC-MSC) efficiently induced AML cell differentiation by shuttling the neutrophil elastase (NE)-packaged extracellular vesicles (EVs) into AML cells. Interestingly, the generation and release of NE-packaged EVs could be dramatically increased by vitamin D receptor (VDR) activation in UC-MSC. Chemical activation of VDR by using its agonist 1α,25-dihydroxyvitamin D3 efficiently enhanced the pro-differentiation capacity of UC-MSC and then alleviated malignant burden in AML mouse model. Based on these discoveries, to evade the risk of hypercalcemia, we synthetized and identified sw-22, a novel non-steroidal VDR agonist, which exerted a synergistic pro-differentiation function with UC-MSC on mitigating the progress of AML. Collectively, our findings provided a non-gene editing MSC-based therapeutic regimen to overcome the differentiation blockade in AML.

ABSTRACT

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

ABSTRACT

Depression is one of the most common psychiatric disorders with high prevalence, disability and relapse rates, and its etiology and pathogenesis are complex and still not fully understood. Neurotransmitters play a key role in maintaining chemical homeostasis in brain, and many studies have shown a strong link between neurotransmitters and the development and treatment of depression in recent years. Therefore, studying the neurotransmitters associated with depression has the potential to provide research targets and ideas for the pathogenesis and treatment strategies of depression. This paper reviews the recent domestic and foreign research results on neurotransmitter function and the pathogenesis of depression, aiming to analyze the in-depth relationship between neurotransmitter function and the pathogenesis of depression, and provide research ideas for the follow-up ex-ploration of the pathogenesis and diagnosis and treatment strategies of depression.

ABSTRACT

Dihydromyricetin is a dihydroflavone compound which widely exists in ampelopsis of grapevine family. It has many pharmacological effects, such as anti-inflammatory, antibacterial, anti-tumor, antioxidant, regulating blood glucose, reducing blood lipid, liver protection and so on. In recent years, it has been found that dihydromyricetin has a good neuroprotective effect and can play a certain pharmacological role in a variety of neurological diseases, including Alzheimer' s disease, depression, Parkinson's disease and stroke. The purpose of this paper is to review the research on the neuroprotective effect of dihydromyricetin in the past decade.

ABSTRACT

A method based on ultra-high performance liquid chromatography coupled with triple quadrupole linear ion trap-tandem mass spectrometry(UHPLC-QTRAP-MS/MS) was developed for the simultaneous determination of 41 bioactive constituents of flavonoids, organic acids, nucleosides, and amino acids in Lysimachiae Herba. The content of multiple bioactive constituents was compared among the samples from different habitats. The chromatographic separation was performed in a Waters XBridge®C_(18) column(4.6 mm×100 mm, 3.5 μm) at 30 ℃. The gradient elution was performed with 0.4% methanol(A)-formic acid water(B) as the mobile phase at a flow rate of 0.8 mL·min~(-1), and the multiple-reaction monitoring(MRM) mode was adopted. According to the content of 41 constituents, hierarchical cluster analysis(HCA), orthogonal partial least squares discriminant analysis(OPLS-DA), and gray relational analysis(GRA) were perfomed to comprehensively evaluate the samples from different habitats. The results showed that the 41 constituents exhibited good linear relationship within the tested concentration ranges, with the correlation coefficients(r) greater than 0.999 4. The method featured good precision, repeatability, and stability with the relative standard deviations(RSDs) less than 5.0%. The average recoveries of the 41 constituents ranged from 98.06% to 101.9%, with the RSDs of 0.62%-4.6%. HCA and OPLS-DA separated 48 batches of Lysimachiae Herba samples from different habitats into three categories: the producing areas in Sichuan and Chongqing, the producing areas in Jiangsu, Zhejiang, and Jiangxi, and the producing areas in Guizhou. The content of 41 constituents varied among the Lysimachiae Herba samples from different habitats. The GRA results revealed that the Lysimachiae Herba sample from Nanchong City, Sichuan Province had the best comprehensive quality. The method developed in this study was accurate and reliable and thus can be used for comprehensive evaluation of Lysimachiae Herba quality and provide basic information for the selection of habitats.
