In recent years, there have been frequent adverse reactions/events associated with traditional Chinese medicine(TCM), especially liver injury related to traditional non-toxic TCM, which requires adequate attention. Liver injury related to traditional non-toxic TCM is characterized by its sporadic and insidious nature and is influenced by various factors, making its detection and identification challenging. There is an urgent need to develop a strategy and method for early detection and recognition of traditional non-toxic TCM-related liver injury. This study was based on national adverse drug reaction monitoring center big data, integrating methodologies such as reporting odds ratio(ROR), network toxicology, and computational chemistry, so as to systematically research the risk signal identification and evaluation methods for TCM-related liver injury. The optimized ROR method was used to discover potential TCM with a risk of liver injury, and network toxicology and computational chemistry were used to identify potentially high-risk TCM. Additionally, typical clinical cases were analyzed for confirmation. An integrated strategy of "discovery via big data, identification via dry/wet method, confirmation via typical cases, and precise risk prevention and control" was developed to identify the risk of TCM-related liver injury. Corydalis Rhizoma was identified as a TCM with high risk, and its toxicity-related substances and potential toxicity mechanisms were analyzed. The results revealed that liver injury is associated with components such as tetrahydropalmatine and tetrahydroberberine, with potential mechanisms related to immune-inflammatory pathways such as the tumor necrosis factor signaling pathway, interleukin-17 signaling pathway, and Th17 cell differentiation. This paper innovatively integrated real-world evidence and computational toxicology methods, offering insights and technical support for establishing a risk discovery and identification strategy for TCM-related liver injury based on real-world big data, providing innovative ideas and strategies for guiding the safe and rational use of medication in clinical practices.

OBJECTIVE: To investigate the expression and potential mechanism of calcium/calmodulin-dependent protein kinase II gamma (CaMKIIγ) in patients with acute myeloid leukemia (AML). METHODS: Peripheral blood samples were collected from 90 AML patients, and mononuclear cells were isolated. The expression of CaMKIIγ was measured using real-time quantitative PCR and Western blot. The diagnostic value of CaMKIIγ for AML was assessed, and its correlation with clinical characteristics was analyzed using the clinical data of patients. Additionally, the molecular mechanisms of CaMKIIγ were preliminarily explored. RESULTS: Compared with the control group, the expression of CaMKIIγ was significantly upregulated in AML patients. Receiver operating characteristic (ROC) curve analysis showed that CaMKIIγ could serve as a promising biomarker for distinguishing AML patients from healthy individuals. Furthermore, CaMKIIγ was significantly correlated with white blood cell (WBC) count and FLT3-ITD mutation. CaMKIIγ was highly expressed in both newly diagnosed and relapsed AML patients, while decreased during remission. In AML cell lines, the expression levels of CaMKIIγ were all elevated. Inhibition of phosphorylated CaMKIIγ by berbamine led to a decrease in pAKT and pSTAT5 expression. CONCLUSION CaMKIIγ is significantly upregulated in AML patients, and is associated with poor clinicopathological features and unfavorable prognosis. It may serve as a prognostic marker and potential therapeutic target in AML. Its expression may be related to the activation of pAKT and pSTAT5, suggesting that CaMKIIγ may contribute to the development and progression of AML through the activation of the AKT/STAT5 signaling pathway.

BACKGROUND: Our understanding of the correlation between postdischarge cancer and mortality in patients with coronary artery disease (CAD) remains incomplete. The aim of this study was to investigate the relationships between postdischarge cancers and all-cause mortality and cardiovascular mortality in CAD patients. METHODS: In this retrospective cohort study, 25% of CAD patients without prior cancer history who underwent coronary artery angiography between January 1, 2011 and December 31, 2015, were randomly enrolled using SPSS 26.0. Patients were monitored for the incidence of postdischarge cancer, which was defined as cancer diagnosed after the index hospitalization, survival status and cause of death. Cox regression analysis was used to explore the association between postdischarge cancer and all-cause mortality and cardiovascular mortality in CAD patients. RESULTS: A total of 4085 patients were included in the final analysis. During a median follow-up period of 8 years, 174 patients (4.3%) developed postdischarge cancer, and 343 patients (8.4%) died. A total of 173 patients died from cardiovascular diseases. Postdischarge cancer was associated with increased all-cause mortality risk (HR = 2.653, 95% CI: 1.727-4.076, P < 0.001) and cardiovascular mortality risk (HR = 2.756, 95% CI: 1.470-5.167, P = 0.002). Postdischarge lung cancer (HR = 5.497, 95% CI: 2.922-10.343, P < 0.001) and gastrointestinal cancer (HR = 1.984, 95% CI: 1.049-3.750, P = 0.035) were associated with all-cause mortality in CAD patients. Postdischarge lung cancer was significantly associated with cardiovascular death in CAD patients (HR = 4.979, 95% CI: 2.114-11.728, P < 0.001), and cardiovascular death was not significantly correlated with gastrointestinal cancer or other types of cancer. CONCLUSIONS Postdischarge cancer was associated with all-cause mortality and cardiovascular mortality in CAD patients. Compared with other cancers, postdischarge lung cancer had a more significant effect on all-cause mortality and cardiovascular mortality in CAD patients.

Objective To explore the relationship between bedtime procrastination and fear of missing out and the intervention effect of aerobic exercise on bedtime procrastination,so as to provide a theoretical basis and practical reference for remedying bedtime procrastination.Methods Totally 988 students were selected through random sampling and then surveyed with the bedtime procrastination scale and the fear of missing out scale.Correlation and regression analyses were performed to explore the relationship between bedtime procrastination and fear of missing out.A total of 36 students were recruited from the 988 students to participate in the exercise intervention and they were assigned into an exercise group and a control group by the random number table method,with 18 students in each group.The exercise group performed aerobic exercise for 12 weeks,while the control group maintained daily activities.The participants' scores on the bedtime procrastination scale and the fear of missing out scale were recorded before and after the intervention and compared.Results The fear of missing out was positively correlated with bedtime procrastination among college students(r=0.214,P<0.001),and it was an important predictive factor for bedtime procrastination(β=0.241,P<0.001).After the intervention,the scores of bedtime procrastination scale decreased in the exercise group(t=2.277,P=0.036),while there was no significant difference in the scores of the control group before and after intervention(t=-0.787,P=0.442).Conclusions A high level of fear of missing out indicates severe bedtime procrastination.And 12-week exercise intervention could remedy bedtime procrastination.

Recent studies on male infertility reveal a growing worry: more infertile men are dealing with inflammation in the testis. Analyzing testicular biopsies from infertile men highlights a significant presence of inflammation. This connection, supported by clinical and pathological evidence, emphasizes that testicular inflammation hampers sperm production, leading to lasting declines in sperm count and quality. However, the exact reasons behind male infertility due to orchitis, a type of testicular inflammation, are still uncertain. Understanding these fundamental aspects of molecular signals and cellular mechanisms in testicular inflammation is crucial. Our review delves into recent literature with a dual objective: elucidating potential mechanisms involving immune cells, non-immune cells, and cytokines that link orchitis to male infertility, while also paving the way for precise interventions and solutions to address the challenges of male infertility.

Objective To investigate the effect of plasma microRNA(miR)-93-5p on ovarian granulosa cell proliferation in patients with polycystic ovary syndrome(PCOS)and its possible mechanism.Methods A total of 120 PCOS patients of childbearing period who were treated at Jiaozuo People's Hospital from January 2022 to January 2023 were selected as the PCOS group,and 18 healthy women of childbearing period who were physically examined at the same hospital during the same period were selected as the control group.The age,body weight and height of the subjects in the two groups were recorded,and the body mass index(BMI)was calculated.Fasting venous blood was collected from the subjects during the follicular phase of the natural menstrual cycle or the progesterone-induced withdrawal bleeding phase,and serum levels of luteinizing hormone(LH),follicle-stimulating hormone(FSH),total testosterone(TT),anti-Mullerian hormone(AMH),aspartate aminotransferase(AST),alanine aminotransferase(ALT),fasting insulin(FINS),and fasting blood glucose(FBG)were measured by using the electrochemical method;and the homeostasis model assessment of insulin resistance(HOMA-IR)was calculated.Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression level of miR-93-5p in plasma of patients in the two groups.Human ovarian granulosa cells(KGN cells)in logarithmic growth phase were cultured in 6-well plates with 3 × 105 cells per well,and they were randomly divided into the miR-93-5p mimics group,LY294002+miR-93-5p group,AZD5363+miR-93-5p group,negative control(NC)group,and blank control group.The KGN cells in the miR-93-5p group were transfected with miR-93-5p mimics;the KGN cells in the LY294002+miR-93-5p group were transfected with miR-93-5p mimics and treated with 50 mmol·L-1 LY294002 one hour before transfection;the KGN cells in the AZD5363+miR-93-5p group were transfected with miR-93-5p mimics and treated with 50 μmol·L-1 AZD5363 one hour before transfection;the KGN cells in the NC group were transfected with the negative control plasmids;and the KGN cells in the blank control group were not treated at all.The expression of miR-93-5p in the KGN cells in each group was detected by qRT-PCR,and the proliferation of the KGN cells in each group was detected by cell counting kit-8.Results There was no significant differences in age,FSH,ALT,and AST levels of patients between the PCOS group and the blank control group(P＞0.05).The BMI,TT,AMH,LH,FINS,FBG,and HOMA-IR of patients in the PCOS group were significantly higher than those in the blank control group(P＜0.05).The relative expression of miR-93-5p in plasma of patients in the PCOS group was significantly higher than that in the blank control group(t=-5.549,P＜0.001).miR-93-5p was moderately positively correlated with TT,FINS and HOMA-IR(r=0.434,0.622,0.586;P＜0.001)and was mildly positively correlated with FBG and LH(r=0.398,0.398;P＜0.001).The receiver operating characteristic curve showed that the optimal cut-off value for plasma miR-93-5p in diagnosing PCOS was 1.380,the area under the curve was 0.906(95％confidence interval:0.839-0.973,P＜0.001),the sensitivity was 0.858,the specificity was 0.833,and the Youden index was 0.691.The relative expression of miR-93-5p in the KGN cells in the miR-93-5p mimics group,LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly higher than that in the blank control group and NC group(P＜0.05).After 24,48 and 72 hours of culture,the proliferation of the KGN cells in the miR-93-5p mimics group,LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly higher than that in the blank control group and the NC group(P＜0.05);the proliferation of the KGN cells in the LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly lower than that in the miR-93-5p mimics group(P＜0.05).Conclusion miR-93-5p in plasma is overexpressed in PCOS patients,and it may be involved in the occurrence and development of PCOS by mediating the proliferation of ovarian granulosa cells through the phosphoinositide 3 kinase/protein kinase B signaling pathway.The miR-93-5p level in plasma has a certain diagnostic value for PCOS.

Objective To explore the expression level of microRNA(miR)-320a-3p in peripheral blood in patients with polycystic ovary syndrome(PCOS)and its possible mechanism for regulating PCOS.Methods A total of 149 PCOS patients admitted to the Jiaozuo People's Hospital from July 2021 to July 2022 were selected as the research subjects(PCOS group),and 18 healthy volunteers with a regular menstrual cycle(28-35 d),no clinical or biochemical manifestations of hyperandrogenism,and no polycystic ovary changes detected by ultrasonography were selected as the control group.Clinical data of the subjects in the two groups were collected and compared.The expression level of miR-320a-3p in plasma of subjects in the two groups was detected by using the real-time quantitative polymerase chain reaction.The correlation between plasma miR-320a-3p expression and clinical indexes was evaluated by using the Pearson partial correlation analysis.The predictive value of miR-320a-3p for PCOS was analyzed by using the receiver operating characteristic curve.The relationship between miR-320a-3p and androgen receptor was evaluated by using the dual luciferase reporter gene assay.Results There was no significant difference in age,hip circumference,follicle stimulating hormone(FSH),prolactin(PRL),and high-density lipoprotein cholesterol(HDL-C)between the two groups(P＞0.05).The body mass index,waist circumference,total testosterone(TT),anti-Miillerian hormone(AMH),luteinizing hormone(LH),fasting insulin(FINS),fasting blood glucose(FBG),2-hour postprandial blood glucose(2 h BG),homeostasis model assessment of insulin resistance(HOMA-IR),total cholesterol,triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C)of patients in the PCOS group were significantly higher than those in the control group,while the level of estradiol(E2)was significantly lower than that in the control group(P＜0.05).The relative expression level of miR-320a-3p in plasma of patients in the PCOS group was significantly lower than that in the control group(P＜0.05).The expression level of miR-320a-3p was moderately negatively correlated with TT(r=-0.594,P＜0.05)and slightly negatively correlated with waist circumference,FINS,2 h BG,HOMA-IR,and LDL-C(r=-0.293,-0.208,-0.227,-0.208,-0.208;P＜0.05),and showed no significant correlation with hip circumference,AMH,FSH,E2,PRL,FBG,TG,and HDL-C(r=-0.079,0.020,-0.042,0.089,0.005,-0.141,-0.116,0.059;P＞0.05).The area under the curve of miR-320a-3p for predicting PCOS was 0.968(95％confidence interval:0.922-1.000,P＜0.05),with a cut-off value of 0.515,a sensitivity of 0.917,a specificity of 0.789,and a Jordon index of 0.706.miR-320a-3p negatively regulated androgen receptors.Conclusion miR-320a-3p is abnormally low expressed in peripheral blood of PCOS patients and may participate in the occurrence and development of PCOS by negatively regulating androgen receptors to increase TT levels.It has high predictive value for diagnosing PCOS.
