Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.

Background Currently,the diagnosis of depressive disorder relies on symptomatology,which is greatly influenced by subjective factors such as clinicians' experience.Finding more accurate and reliable quantitative diagnostic methods is currently an urgent problem.Objective To explore the value of Fisher discriminant function based on inflammatory cytokines in the diagnosis of depressive disorder,so as to provide references for clinical diagnosis.Methods A total of 136 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)criteria,who underwent inpatient treatment at Hebei Mental Health Center from April 2020 to November 2020,were enrolled as study group.67 healthy participants matched for age and gender,was recruited during the same period.Serum levels of inflammatory cytokine were measured using enzyme-linked immunosorbent assay(ELISA).Fisher discriminant model was employed to establish a discriminant function for inflammatory cytokines exhibiting significant statistical differences between study group and control group,which was then validated.Results The levels of pro-inflammatory cytokines interleukin-1β(IL-1β),interleukin-6(IL-6),interferon-γ(INF-γ)and tumor necrosis factor-α(TNF-α)were higher in the study group compared with control group,with statistically significant differences(U=9.115,5.239,4.431,5.428,P<0.01).Conversely,the levels of anti-inflammatory cytokines interleukin-4(IL-4),interleukin-10(IL-10)and interleukin-13(IL-13)were lower in the study group compared with control group,with statistically significant differences(U=7.398,7.331,7.614,P<0.01).The retrospective test in Fisher discriminant function achieved a correct discrimination rate of 89.66%,and the cross validation achieved a correct discrimination rate of 88.67%.Conclusion The Fisher discriminant function developed in this study may serve as a valuable auxiliary method in the diagnosis of depressive disorder.

Objective:To study the diagnostic value of artificial intelligence B-ultrasound image computer-aided diagnosis system (hereinafter referred to as intelligent ultrasound system) in adult goiter.Methods:In June 2022 and March 2023, two phases of thyroid disease survey were carried out in 4 cities in Anhui Province. One village was selected in each city, and 250 adults were selected as survey subjects in each village. Adult bilateral thyroid area was scanned by both intelligent ultrasound system and conventional ultrasound scanning equipment, and the effectiveness of intelligent ultrasound system in the diagnosis of goiter was analyzed based on the results of conventional ultrasound examination. Receiver operating characteristic (ROC) curve was drawn, and Kappa test was used to analyze the consistency between intelligent ultrasound system and conventional ultrasound examination in the diagnosis of goiter. At the same time, Spearman correlation analysis and Bland-Altman method were used to evaluate the consistency of the two methods in measuring thyroid volume.Results:After screening and removing outliers and missing values, a total of 910 adults were included, including 253 males (27.80%) and 657 females (72.20%). The age was (45.92 ± 10.20) years old, ranging from 18 to 60 years old. The sensitivity, specificity, and accuracy of the intelligent ultrasound system for diagnosing adult goiter were 80.00%, 99.67%, and 99.56%, respectively. The area under the ROC curve (AUC) was 0.996, which was consistent with the results of conventional ultrasound examination for diagnosing goiter ( κ = 0.67, P < 0.001). After controlling for variables such as gender, thyroid function, and thyroid nodules, the intelligent ultrasound system showed good consistency with conventional ultrasound examination in the diagnosis of goiter in females, adults with thyroid dysfunction, and adults without thyroid nodules ( κ = 0.66, 0.80, 0.80, P < 0.001). The consistency in the diagnosis of goiter in adults with thyroid nodules was moderate ( κ = 0.56, P < 0.001). Spearman correlation analysis showed a highly positive correlation between the measurement results of adult thyroid volume by intelligent ultrasound system and conventional ultrasound examination ( r = 0.88, P < 0.001). The Bland-Altman method results showed that only 4.62% (42/910) of points in adults were outside the 95% consistency limit, indicating good consistency between intelligent ultrasound system and conventional ultrasound examination in measuring thyroid volume (< 5%). The proportion of points outside the 95% consistency limit in males, adults with thyroid dysfunction, and adults with thyroid nodules was 6.72% (17/253), 5.83% (12/206), and 6.45% (12/186), respectively. Conclusions:The intelligent ultrasound system has certain diagnostic value for adult goiter and has good consistency with conventional ultrasound examination for thyroid volume measurement. However, the accuracy of diagnosis for males and adults with thyroid nodules still needs to be improved.

Objective:To investigate the brain functional connectivity and network of patients with bipolar depression (BD) during emotion recognition, and to assess the correlation of brain functional indicators with clinical data.Methods:From August 2023 to September 2024, a total of 34 BD patients and 35 healthy controls were recruited for the study. The 17-item Hamilton depression scale(HAMD-17) and the Hamilton anxiety scale (HAMA) were used to assess the depression and anxiety symptoms of BD patients. While all the participants performed the emotion recognition task, a functional near-infrared spectroscopy (fNIRS) with 52 channels was utilized to collect their oxyhemoglobin concentrations in dorsolateral prefrontal cortex (DLPFC), medial prefrontal cortex (mPFC), and temporal lobe (TL). Brain functional indicators, including brain functional connectivity(BFC) and brain functional network (BFN) parameters, were extracted using fNIRS analysis algorithms. SPSS 26.0 software was used to perform t-test, Wilcoxon rank sum test, chi-square test, Pearson correlation and multiple linear regression analysis. Results:The emotion recognition accuracy of BD patients ((69.40±18.32) %) was lower than that of healthy controls ((76.94±6.09)%)( t=-2.13, P=0.036), and the average spending time ((4.00±1.78) s) of BD patients was longer than that of healthy controls ((2.69±1.27) s) ( t=-2.81, P=0.007). The BFC values of right DLPFC-right mPFC, right DLPFC-left TL, right DLPFC-left mPFC, right TL-right mPFC, right TL-left TL, right TL-left mPFC, right mPFC-left DLPFC, and right mPFC-left mPFC, the clustering coefficient, and small-world coefficient of BD patients were lower than those of healthy controls (all P<0.05).The characteristic path length of BD patients was higher than that of healthy controls ( t=1.27, P<0.05). For BD patients, the total score of HAMD-17 were significantly and negatively correlated with the clustering coefficient, small-world coefficients, and BFC values of right DLPFC-left mPFC and right mPFC-left DLPFC ( r=-0.45--0.27, all P<0.05).The total score of HAMA was significantly and positively correlated with the BFC value of right DLPFC-left mPFC ( r=0.30, P<0.05). The results of multiple linear regression analysis showed that the clustering coefficient ( β=-0.12, t=-0.69, P=0.009), small-world coefficients ( β=-0.22, t=-1.05, P=0.013), and BFC values of right DLPFC-left mPFC ( β=-0.47, t=-2.29, P=0.030) and right mPFC-left DLPFC( β=-0.20, t=-0.90, P=0.010) were influencing factors of depressive symptoms in BD patients. The BFC value of right DLPFC -left mPFC ( β=0.37, t=2.36, P=0.026) was influencing factor for anxiety symptoms in BD patients. Conclusions:There are abnormalities in some BFC values and BFN parameters in the DLPFC, mPFC, and TL brain regions during the emotional recognition task, which are related to the clinical symptoms. The abnormalities may be associated with the emotional recognition deficits in BD patients. These findings may provide theoretical guidance for the development of clinical intervention strategies for BD patients.

Objective:To evaluate the performance of the self-developed transcranial ultrasound patch probe as well as its stability and safety in clinical applications.Methods:This study was a cross-sectional study. Fifty healthy subjects in Tangdu Hospital from October to December 2023 were randomly and equally divided into two groups using a simple randomization method. The transcranial Doppler ultrasound (TCD) examinations were performed using the self-developed transcranial ultrasound patch probe and normal TCD probe alternatively in each group from squatting to sitting and then to standing posture. Two experienced sonographers (A, B) each completed one test for the same subject using the above two different probes. The differences of the ultrasound parameters of middle cerebral artery (MCA) blood flow measured by the self-developed transcranial ultrasound patch probe and the normal TCD probe in different postures (squatting, sitting, standing) were compared. At the same time, operator satisfaction with the use of the two probes was assessed in terms of time taken to obtain satisfactory images, operational comfort, and ease of handling. In addition, the subject's comfort during the examination was examined, and the signal acquisition stability of the two probes was comprehensively evaluated.Results:There was no significant difference in detection of various ultrasound parameters of MCA between using the transcranial patch probe and the normal TCD probe (all P>0.05). The overall satisfaction of transcranial ultrasound patch probe and normal TCD probe was quite similar. The transcranial ultrasound patch probe acquired favorable and stable signals. No subjects experienced adverse events/accidents during the examination of the subjects using the transcranial ultrasound patch probe as well as the normal TCD probe.Both probes had good and stable signal acquisition. Conclusions:TCD examinations could be well performed using the transcranial ultrasound patch probe, which might provide a potential new method for real-time monitoring and evaluating of cerebral blood flow of a moving subject.

Objective:To elucidate the quasispecies variation of 3′ half-length genome in HIV-1 CRF103_01B-infected patients in Beijing using single genome amplification (SGA).Methods:This study enrolled six CRF103_01B-infected patients who were diagnosed during a drug resistance monitoring for newly diagnosed cases or newly treated cases with antiviral therapy in Beijing from 2017 to 2020. RNA was extracted from their plasma samples, and 3′ end of cDNA was diluted by serial dilution method after reverse transcription. Nested PCR was used to amplify the 3′ half-length genome sequences of HIV-1 quasispecies. MEGA 11 was used to construct Neighbor-Joining (NJ) tree and calculate the intrahost genetic distance. Genetic variation in HIV-1 quasispecies was visualized by online Highlighter tool. BootScan analysis was performed using Simplot 3.5 software to analyze inter-quasispecies recombination. Virus tropism was predicted by online Geno2pheno tool.Results:Among the six CRF103_01B-infected patients, five were men who have sex with men. A total of 144 3′ half-length genome SGA sequences (19-36 sequences/case) were obtained. The NJ tree based on the 3′ half-length genome of HIV-1 quasispecies revealed different degrees of genetic diversity. The HIV-1 quasispecies in BL4748-00 case of acute infection has the least variation with the intrahost distance of 0.002±0.000, showing genetic homogeneity. The quasispecies sequences from BL4981-00, BL3150-00 and BL3558-00 cases formed at least three subclusters, respectively, with different evolutionary directions, and their intrahost distance ranked from 0.031±0.004 to 0.016±0.002 (BL3150-00>BL3558-00>BL4981-00). The quasispecies sequences from the couple BL3022-00 (female) and BL3023-00 clustered into a large monophyletic cluster (bootstrap value=100%), and the intrahost distance of the latter (0.025±0.003) was higher than that of the former (0.019±0.002). Inter-quasispecies recombination was observed in BL3558-00 case. The quasispecies from the six patients were CCR5-tropic viruses.Conclusions:The diversity of quasispecies variation in CRF103_01B-infected patients is related to disease progress. Genetic homogeneity is observed in acute HIV infection, while multiple evolutionary directions are detected in chronic infection. Co-infection or superinfection cases are not found, but there are recombination events among quasispecies in some cases.

MethodThe chemical components of Kunning granules were analyzed by ultra high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry（UHPLC-Q-TOF-MS/MS） on a Waters ACQUITY UPLC HSS T3 column（2.1 mm×100 mm， 1.8 μm） with the mobile phase of acetonitrile（A）-25 mmol∙L^-1 ammonium acetate aqueous solution（B） for gradient elution （0-5 min， 5%-22%A； 5-10 min， 22%-30%A； 10-15 min， 30%-95%A； 15-20 min， 95%-5%A； 20-30 min， 5%A）， flow rate of 0.2 mL∙min^-1， column temperature at 30 ℃， injection volume of 1 μL， electrospray ionization（ESI）， positive and negative ion detection modes. Interaction analysis between the targets of chemical components and the targets of abnormal uterine bleeding（AUB） was performed by network pharmacology， and the key components were screened through network topology analysis. The fingerprints of 10 batches of Kunning granules were established by high performance liquid chromatography（HPLC）， the anticoagulant activity of the granules was determined by blood coagulation method and fibrinogen plate method， and the spectrum-effective relationship was established. The components co-occurring in the topological analysis and spectrum-effective relationship were selected as Q-Markers， and their anticoagulant activities were verified and confirmed. ResultA total of 475 chemical components were identified from Kunning Granule， of which 22 key components such as salvianolic acid B， paeoniflorin， naringin and neohesperidin， were the potential material basis for the treatment of AUB. The spectrum-effective analysis showed that peaks 7（paeoniflorin）， 9（naringin）， 10（neohesperidin） and 11（salvianolic acid B） were the optimal principal components， and in vitro activity test showed that these four components could better characterize their anticoagulant activity. ConclusionSalvianolic acid B， paeoniflorin， neohesperidin and naringin may be Q-Markers for the anticoagulant activity of Kunning granules.

Carbonic anhydrase IX (CAIX) is a transmembrane protein that is specifically overexpressed on the surface of hypoxic tumor cells. With the function of regulating the acidity of tumor cells both inside and outside, CAIX is closely related to tumor proliferation, invasion and metastasis. Therefore, CAIX is a promising target for tumor imaging and therapy. Herein, we summarized recent advances in CAIX-based tumor imaging, therapy and theranostics, and prospected future applications of using CAIX as an anti-tumor target.
