Diabetic retinopathy(DR)is one of the common serious microvascular complications in diabetic patients,with the main pathological features of retinal vascular injury,oxidative stress and chronic inflammatory re-sponse.In recent years,more and more studies have shown that mitophagy plays an important role in maintaining the func-tional homeostasis of retinal cells and preventing oxidative damage,and nucleotide-binding oligomerization domain-like re-ceptor protein 3(NLRP3)is a key regulator of pro-inflammatory response in DR.Mitophagy can reduce the excessive pro-duction of reactive oxygen species(ROS)by removing damaged mitochondria,thereby inhibiting the activation of NLRP3 inflammasome.In contrast,mitochondrial dysfunction can lead to excessive activation of NLRP3 inflammasome,which further aggravates the inflammatory response and apoptosis of the retina.Therefore,this article reviews the independent role of mitophagy and NLRP3 inflammasome in DR and their mutual regulatory mechanisms,so as to provide reference for the study of mitophagy and NLRP3 inflammasome as targets.

Objective To investigate the clinical features of chronic hepatitis C(CHC)patients with hepatitis C virus genotype 3(HCV GT3)infection and the risk factors for disease progression.Methods A multicenter retrospective cohort study was conducted among 1 002 CHC patients from 11 clinical centers in Northwest China from December 2017 to November 2023,and according to their genotype,they were divided into GT1,GT2,GT3,and GT6 groups.Clinical features were compared between the patients with different genotypes.The one-way analysis of variance was used for comparison of normally distributed continuous data between groups,and the Scheffe test was used for further comparison between two groups.The Kruskal-Wallis H test was used for comparison of data with skewed distribution between groups;the chi-square test or Fisher test was used for comparison of categorical data between groups.The multivariate logistic regression analysis was used to explore the influencing factors for the progression of CHC to liver cirrhosis.Results In terms of the genotype,there were 427 patients with GT1 infection,242 with GT2 infection,299 with GT3 infection(210 patients with GT3a infection,87 with GT3b infection,and 2 with unclassified genotype),and 34 with GT6 infection.The patients with GT3 infection had a significantly younger age than those with GT1 infection(51.3±0.5 years vs 53.2±0.6 years,P<0.05)or GT2 infection(51.3±0.5 years vs 53.7±0.8 years,P<0.05),and for the patients with liver cirrhosis,the patients with GT3 infection had a significantly younger age than those with GT1 infection(52.1±0.5 years vs 59.4±0.9 years,P<0.001)or GT2 infection(52.1±0.5 years vs 58.1±1.1 years,P<0.001).Among the patients with GT3 infection,male patients accounted for 77.9%and the patients with liver cirrhosis accounted for 46.2%,which were significantly higher than those among the patients with GT1,GT2 or GT6 infection(all P<0.001).At baseline,the patients with GT3 infection had significantly higher levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)than those with GT1 or GT2 infection,significantly higher aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4(FIB4)than those with GT1,GT2 or GT6 infection,a significantly lower platelet count(PLT)than those with GT2 or GT6 infection,a significantly higher level of alpha-fetoprotein than those with GT2 or GT6 infection,and a significantly lower level of albumin(Alb)than those with GT6 infection(all P<0.05).There were no significant differences between the patients with GT3a infection and those with GT3b infection in age,sex,the proportion of patients with liver cirrhosis,comorbidities,HCV RNA quantification,PLT,ALT,AST,alkaline phosphatase,Alb,APRI,and FIB-4(all P>0.05).The multivariate logistic regression analysis showed that PLT≤150×109/L(odds ratio[OR]=10.72,95%confidence interval[CI]:5.76-35.86,P<0.001)and Alb≤35 g/L(OR=3.74,95%CI:1.22-11.45,P=0.021)were risk factors for liver cirrhosis.Conclusion Most CHC patients with GT3 infection are male in Northwest China,and compared with the patients with other genotypes,such patients tend to have a younger age of onset and higher degrees of liver inflammation activity and fibrosis.Low PLT and a low level of Alb are risk factors for progression to liver cirrhosis in CHC patients with GT3 infection.

Objective:To explore the neurophysiological features of the prefrontal-limbic-striatal circuit in patients with early-stage bipolar disorder without manic or hypomanic episodes, and its role in identifying early-stage bipolar disorder.Methods:From 2009 to 2019, a total of 155 hospitalized patients with major depressive disorder (MDD) from Nanjing Brain Hospital were selected after at least 5 years of follow-up, 31 patients with depression transitioned to bipolar disorder(ctBD group) and 76 patients remained the diagnosis of MDD(MDD group) were recruited.Sixty-two healthy controls matched for age, gender, and education years were selected as control group(HC group). Resting-state magnetoencephalography (MEG) data in eyes-open state of all subjects were collected.Data were analyzed based on the fieldtrip toolkit on the MATLAB platform. The key brain area of the prefrontal-limbic-striatal circuit were selected. Inter-group statistical analysis were conducted on the spectral energy and power-correlated functional connectivity at the theta, alpha, beta, and gamma frequency bands in the brain area of interest. In addition, the prediction model was constructed to early recognize bipolar disorder.Results:(1)There were statistically significant differences in the spectral energy of theta and alpha frequency bands in the prefrontal-limbic-striatal circuit among the 3 groups (cluster- F=120.50, 112.39, both P<0.05). The spectral energy of theta and alpha frequency bands in interest brain regions of prefrontal-limbic-striatal circuit in MDD group was lower than that in HC group (cluster- t=89.52, P<0.05). The spectral energy of theta band in prefrontal-limbic-striatal circuit in ctBD group was lower than that in HC group(cluster- t=105.82, P<0.05), and the spectral energy of alpha band in inferior frontal gyrus, orbitofrontal gyrus and caudate nucleus was lower than that in HC group (cluster- t=75.78, P<0.05), while there was no significant difference between the MDD group and the ctBD group ( P>0.05).(2)After FDR correction, there were statistically significant differences in functional connectivity between the left orbitofrontal gyrus and the right ventral striatum among the three groups (0.26 (0.13, 0.34), 0.12 (0.09, 0.24), 0.27 (0.20, 0.37), H=13.51, P<0.05, FDR correction). The strength of functional connectivity between the left orbitofrontal gyrus and the right ventral striatum in the MDD group was weaker than that in the HC group and the ctBD group (all P<0.05).(3)Binary Logistic regression analysis showed that the functional connectivity of beta frequency band between the left orbitofrontal gyrus and the right ventral striatum ( B=1.50, OR=4.50, 95% CI=1.73-11.70), the functional connectivity between the right orbitofrontal gyrus and the right amygdala( B=0.98, OR=2.68, 95% CI=1.18-6.13), the total HAMD score ( B=0.80, OR=2.28, 95% CI=1.36-3.67), the body weight factor score ( B=-1.99, OR=0.14, 95% CI=0.04-0.45), the anxiety factor score ( B=-0.99, OR=0.37, 95% CI=0.19-0.71), and sleep factor score( B=-1.14, OR=0.32, 95% CI=0.16-0.65)were the influencing factors for depression transitioned to bipolar disorder. Conclusion:The decreased resting low-frequency energy in the prefrontal-limbic-striatal circuit may be the common neural basis for the onset of unipolar and bipolar depression, and enhanced functional connectivity may be a potential neural circuit mechanism for depression transitioned to bipolar disorder. Functional connectivity combined with clinical manifestations is helpful for early recognition of bipolar disorder.

Thirty SPF Kunming male mice aged 6-8 weeks were randomly divided into five groups:the control group,the model group,and the low,medium,and high dose groups of Dilong.Except for the control group,the other mice were continuously injected intraperitoneally with 80 mg/kg cyclophosphamide for 3 days to prepare an immunosuppressive model.After the model-ing was completed,the control group and the model group were given an equal amount of physio-logical saline by gavage,while the low,medium,and high dose Dilong groups were given 100,200,and 400 mg/kg of Dilong fermented material by gavage,respectively.The treatment lasted for 14 days,and thymus,spleen,blood,and intestinal contents were collected 2 hours after the last admin-istration.The results showed that cyclophosphamide caused a weight loss in mice during the exper-iment,reduced thymus index,white blood cells,lymphocytes,granulocytes,immunoglobulin levels in the blood,and disrupted gut microbiota.Dilong fermented material can effectively improve the decrease in body weight and thymus index of mice,increase the levels of immune cells and immu-noglobulin in the blood,improve the diversity and richness of intestinal microbiota,and increase the abundance of beneficial bacteria.Dilong fermented can effectively alleviate the immune suppres-sion and intestinal microbiota disorder caused by cyclophosphamide in mice.Considering all fac-tors,the optimal dosage is 200 mg/kg.

Objective:To explore the differences in the whole-brain functional connectivity characteristics of magnetoencephalography gamma sub-band in resting state between patients with depression with high and low suicidal ideation.Methods:Clinical data of 60 patients with depression (depression group) who visited the Department of Psychiatry, Nanjing Brain Hospital Affiliated to Nanjing Medical University from October 2021 to June 2024 were prospectively collected, including 20 males and 40 females aged 16-41 years. During the same period, 75 healthy controls (healthy control group) were recruited, matched for gender and age, comprising 33 males and 42 females, aged 18-43 years. The Hamilton Depression Scale-17 items (HAMD-17) was used to assess the degree of depression in patients, and the score of the third item was used to divide the patients into a high suicidal ideation group of 37 cases (2-3 points) and a low suicidal ideation group of 23 cases (0-1 points). The Beck Scale for Suicide Ideation-Chinese Version (BSI-CV) was used to assess the intensity of suicidal ideation in patients in the last week and at the most severe stage. Brain imaging data of the subjects were collected using a CTF-275 channel magnetoencephalography device and a 3 T magnetic resonance imaging device. The functional connectivity matrix of the gamma sub-band depression group, healthy control group, high suicidal ideation group, and low suicidal ideation group was calculated using the envelope correlation method. The network-based statistics (NBS) algorithm was used to correct for multiple comparisons and compare the differences in brain network functional connectivity between the depression group/healthy control group and between the high/low suicidal ideation groups.Results:Compared with the healthy control group, the functional connectivity between the bilateral middle frontal gyrus, right inferior frontal gyrus orbital part, right anterior cingulate gyrus, left middle frontal gyrus orbital part, and right superior parietal lobule in the depression group was significantly enhanced in the low gamma frequency band (30-60 Hz) ( θ=3, P=0.042). Compared with the low suicidal ideation group, the functional connectivity between the right amygdala as a central node and the right superior frontal gyrus, left hippocampus, right upper temporal pole, and left transverse temporal gyrus in the high suicidal ideation group was significantly enhanced in the high gamma frequency band (60-90 Hz) ( θ=3, P=0.049). Conclusion:In the low gamma frequency band, patients with depression have neural dysfunction mainly in the frontal lobe. In the high gamma frequency band, patients with high suicidal ideation have functional connectivity abnormalities centered on the amygdala.

Objective To compare the effects of single antiplatelet therapy(SAPT)versus dual antiplatelet therapy(DAPT)on bleeding and ischemic events in patients undergoing transcatheter aortic valve replacement(TAVR)without long-term anticoagulation indications.Methods This randomized controlled trial included 90 post-TAVR patients without anticoagulation indications,who were allocated to the SAPT group(n=46,aspirin 100 mg/d)or DAPT group(n=44,aspirin 100 mg/d+clopidogrel 75 mg/d for 3 months,followed by aspirin monotherapy).Maximum aggregation rates of platelets induced by arachidonic acid(MARAA)and adenosine diphosphate(MARADP)were measured 1,3,6,and 12 months postoperatively.Bleeding and ischemic events were recorded during the follow-up visits.Results The SAPT group exhibited significantly higher MARAA and MARADP scores at 1 and 3 months,and higher MARAA scores at 6 months compared to the DAPT group(P<0.05).At the 12-month follow-up,the SAPT group had a significantly lower inci-dence of bleeding events compared to the DAPT group(13.0%vs.31.8%,P=0.043).No statistically significant difference was observed in ischemic events between the groups(15.2%vs.11.4%,P=0.759).Conclusion For TAVR patients without anticoagulation indica-tions,SAPT significantly reduced the 1-year bleeding risk compared to DAPT,without increasing ischemic events.These findings support the safety and efficacy of SAPT after TAVR.

The oropouche virus (OROV) poses a threat to pregnant women and fetuses, potentially causing fetal neurological defects and even stillbirth, which has caused global attention. OROV is an arthropod-borne virus belonging to the Orthobunyavirus genus in the Bunyavirales order, primarily transmitted by arthropods and causing oropouche fever. This article reviews the etiological characteristics, epidemiological distribution, clinical symptoms, detection methods, and prevention strategies of OROV. OROV is prevalent in Central and South America, with a sharp increase in cases reported in Brazil in 2024. The virus's symptoms resemble those of several other arthropod-borne viral diseases, which can lead to misdiagnosis. Currently, there are no specific drugs or vaccines available, and treatment is mainly supportive. Culicoides paraensis and Culex quinquefasciatus are among the significant vectors of OROV. Furthermore, the article analyzes the distribution of Culex quinquefasciatus in China, highlights the risk of imported cases, proposes targeted prevention and control strategies, and underscores the significance of international cooperation in disease prevention and control.
