Objective To investigate the effect of Danshen Baoxin Cha (DBC) on a rat model of coronary heart disease combined with cognitive impairment. Methods Male Sprague-Dawley(SD) rats were randomly assigned to two groups:normal group and model group. Streptozotocin was injected into the bilateral ventricles of rats in the model group to establish cognitive impairment model,then isoproterenol hydrochloride was injected subcutaneously to model myocardial ischemia. Behavioral experiments were conducted to verify the success of the model of cognitive dysfunction. The rats of the model group were randomly divided into five groups:model control group,Tongxinluo Capsule group (TXL group,1.6 g·kg-1),and low-(4 g·kg-1),medium-(8 g·kg-1),and high-(16 g·kg-1) dose DBC groups. These groups were received the respective treatments continuously for two weeks. Subsequently,the Y-maze,novel object recognition and Morris water maze experiment were employed to assess the learning and memory abilities of rats. A kit was utilized to quantify the level of oxidative stress in the brain and the adenosine triphosphate (ATP) content in the brain and mitochondria. Hematoxylin-eosin (HE) staining and Nissl staining were employed to observe the pathological changes of neurons in hippocampus CA1 region. Electron microscopy was utilized to observe the pathological changes of mitochondria in hippocampal CA1 region. The expression levels of peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α),glucose transporter type 4(GLUT4),and optic atrophy 1(OPA1) were quantified by real-time fluorescence quantitative polymerase chain reaction (PCR),and the expression of proteins related to the AMPK/OPA1 signaling pathway was determined by Western Blot analysis. Results Compared with the normal group,the spontaneous alternating reaction rate,the novel object recognition index,number of crossing the original platform,and distance ratio in the model group were obviously decreased (P<0.01). Neuronal density in the CA1 region of the hippocampus was decreased,Nissl bodies were decreased,and nucleus consolidation was increased. The ATP level in mitochondria,and the levels of ATP,SOD,and GSH-PX in brain were significantly decreased(P<0.05,P<0.01),as well as the content of ROS and MDA were significantly increased (P<0.05,P<0.01). The mitochondria of hippocampus in CA1 region were swollen,with sparse and vacuolated cristae. The mRNA expression levels of GLUT4,PGC-1α,and OPA1 were significantly decreased (P<0.01). The protein expression levels of GLUT4,SIRT1,PGC-1α and OPA1,and p-AMPK/AMPK ratio were significantly decreased (P<0.05,P<0.01). Compared with the model group,the behavioral indexes of rats in the DBC groups were significantly improved (P<0.05,P<0.01),the number of neurons in the hippocampal CA1 area,Nissl bodies and nucleus consolidation were improved. The ATP level in mitochondria and the levels of ATP,SOD,and GSH-PX in brain were significantly increased (P<0.05,P<0.01). The levels of ROS and MDA were significantly decreased (P<0.05,P<0.01). The structure of mitochondrial cristae in hippocampal CA1 region were relatively intact. The mRNA expression levels of GLUT4,PGC-1α and OPA1 were increased (P<0.05,P<0.01),and the expression of proteins related to the AMPK/OPA1 signaling pathway was significantly increased(P<0.05,P<0.01). Conclusion DBC can enhance learning and memory abilities,reduce neuronal damage in a rat model of coronary heart disease combined with cognitive impairment. The mechanism may be related to the reduction of oxidative stress damage in the brain,the activation of the AMPK/OPA1 signaling pathway,and the restoration of energy levels.

Objective To explore the mechanism of action of Danshen Baoxin Cha(DBC) on depressed mice with coronary heart disease (CHD) based on network pharmacology and NLRP3 inflammatory pathway. Methods (1) TCMSP and BATMAN-TICAM databases were used to screen the DBC active ingredients and targets. The targets of CHD with depression were screened using the OMIM and Genecards databases. The targets of DBC active ingredients and related targets of CHD with depression were imported into Venny 2.1 online platform to obtain the intersection targets,which was the potential target of DBC in the treatment of CHD with depression. Protein-protein interaction (PPI) analysis was performed on the intersection targets using the STRING platform to screen the key targets. A "drug-active ingredients-disease-targets" network was created to select the main active ingredients and core targets of DBC for the treatment of CHD with depression. Thereafter,the primary targets were examined by GO function and KEGG pathway enrichment using the Metascape database.(2)Kunming mice were split into six groups of eight mice each at random:the control group,the model group,the positive control group (metoprolol tartrate 5.14 mg·kg-1+sertraline hydrochloride 10.3 mg·kg-1),and the DBC high-,middle-,and low-dose groups (30.8,15.4 and 7.7 g·kg-1·d-1). Chronic unpredictable mild stimulation (CUMS)and subcutaneous injection of isoprenaline hydrochloride (ISO) were used to induce a mice model of CHD with depression. Mice were treated orally with the corresponding drug once a day for 18 consecutive days. Behavioral experiments involving forced swimming test,tail suspension test,and open-field test were applied to detect depression levels of mice. Histopathological alterations in hippocampus tissues were noted using HE and Nissl staining. qPCR was used to determine the mRNA expression levels of IL-6,TNF-α,NLRP3,IL-1β,IL-10,and Caspase-1 in hippocampus tissues. Results(1) Sixty-five active components in Salvia and seven active components in green tea were screened out. A total of 1042 potential targets and 2116 CHD complicated with depression-related targets were obtained. The intersection of the targets of active components and disease-related targets was performed by Venny 2.1.0 platform to obtain 299 potential targets (common targets) of DBC in the treatment of CHD with depression. The core targets including IL-1β,AKT1,TNF-α,IL-6,VEGFA,CASP3 and IL-10 were screened through PPI network analysis of potential targets. Key active ingredients including vitamin B,luteolin,salvianolic acid,tanshinone ⅡA and catechin,as well as key targets,such as PTGS2、IL-1β、IL-6、TNF-α and IL-10,were obtained by network analysis of "drugs-active ingredients-disease-targets". The potential targets were correlated with biological processes such as inflammation response,regulation of tumour necrosis factor (TNF),glucocorticoid regulation,regulation of nuclear factor kappa B(NF-κB) transcription factor,as well as major pathways including PI3K-Akt signaling pathway,TNF signaling pathway,apoptosis signaling pathway,and NF-κB signaling pathway.(2) Compared with the control group,mice in the model group showed a significant decrease in the total and center distance of the open field (P<0.01) and a significant increase in the time of forced swimming and immobility time of tail suspension test (P<0.01). The mRNA expression of IL-6,TNF-α,NLRP3,IL-1β,and Caspase-1 was significantly up-regulated(P<0.01) in the hippocampus tissues,but IL-10 mRNA expression was down-regulated (P<0.05). Compared with the model group,the total and center distance in DBC high-,middle-,and low-dose groups were significantly up-regulated(P<0.05,P<0.01),and the time of forced swimming and immobility time of tail suspension test were significantly down-regulated (P<0.01). The mRNA expression of IL-6,TNF-α,NLRP3,IL-1β and Caspase-1 of the DBC high-,middle-,and low-dose groups were significantly down-regulated(P<0.01),IL-10 mRNA expression in mice hippocampus tissue of DBC high-and middle-dose groups was up-regulated (P<0.01). Conclusion The intervention effect of DBC on depressed mice with CHD may be achieved by active ingredients including luteolin,tanshinone,salvianolic acid and catechin acting on the key targets,such as IL-6,TNF-α,IL-1β and IL-10,to regulate the NLRP3 inflammatory signaling pathway.

Objective:To investigate the clinical efficacy of the new bridging combined internal fixation system in the treatment of irregular bone fractures.Methods:Retrospectively analyzed the complete case data of 32 patients with displaced mid-clavicle fractures treated with bridging combined internal fixation system from June 2021 to September 2023 at Suzhou Hospital of Nanjing Medical University, including 20 males and 12 females, with ages ranging from 25 to 65 years old, and an average of 37.5 years old. The operation time, operative bleeding, incision length, hospitalization days, fracture healing time, and postoperative related complications were recorded, and the shoulder joint function was evaluated by Constant-Murley scoring system at the final follow-up.Results:The operation time was (45.5±10.0) min; the hospitalization time was (5.0±2.1) days; the length of the surgical incision was (8.5±1.2) cm; the intraoperative bleeding was (25.0±10.2) mL; 32 patients were followed up until the fracture was healed, and the time of fracture healing was (4.5±2.2) months. One case of a thin female patient with thin subcutaneous tissues had a bulging of the skin and a feeling of discomfort after the operation and no complaint of discomfort after removal of the internal fixation after 6 months. After 6 months, the fracture healed and there was no complaint of discomfort after removal of the internal fixation. None of the other patients had complications such as postoperative infection, fracture non-union, or loosening of the internal fixation. The Constant-Murley score of all patients at the last follow-up points) was significantly improved compared with that of the preoperative period [(92.0±5.0) vs (50.0±6.0), P<0.05]. Conclusion:As a new type of internal fixation, the bridging combined internal fixation system has clear clinical efficacy in the treatment of displaced mid-clavicle fractures, with high plasticity of internal fixation and stable fixation in multiple planes, which provides a new choice for the treatment of displaced mid-clavicle fractures.

Objective:To explore the clinical value of 68Ga-pentixafor PET/CT targeting for CXCR4 in the diagnosis and prognosis evaluation of primary aldosteronism (PA). Methods:Retrospective analysis was performed on information of 72 patients diagnosed with PA who received operations according to the results of 68Ga-pentixafor PET/CT in our hospital. There were 37 males and 35 females, with the average age of (48.3±9.5) years old. The average lesion diameter was (1.60 ± 0.54)cm. The preoperative systolic and diastolic blood pressure were (177.3 ± 23.9)mmHg and (107.6 ± 13.2)mmHg, respectively. The average preoperative potassium level was (2.62 ± 0.56)mmol/L. The average aldosterone concentration was (17.98 ± 4.66)ng/dl, and the median plasma renin activity was 0.01 (0.01, 0.09) ng/(ml·h). All patients underwent 68Ga-pentixafor PET/CT examination, which lead to the decision of surgical strategies. For those patients with single lesion, multiple lesions in one side or positive lesion in one side but negative in the opposite side, surgical resection of the positive side lesion or total adrenalectomy was considered. For those patients with bilateral positive lesions, surgical resection of the side with more significant positive lesions or total adrenalectomy was considered. For those with negative multiple lesions, the surgical strategy was designed according to the results of CT examination or AVS. The positive rate of 68Ga-pentixafor PET/CT and its relationship with the clinical characteristics and prognosis of patients were analyzed. Results:The results of 68Ga-pentixafor PET/CT were positive in 62 of 72 patients diagnosed with PA (86.1%), and the median SUVmax value was 11.1 (7.1, 16.2). The SUVmax value was positively correlated with the maximum diameter of adrenal lesion ( r=0.468) and negatively correlated with blood potassium levels ( r=-0.437), while not significantly correlated with other clinical characteristics. The positive rate of adenoma by 68Ga-pentixafor PET/CT was higher than that of nodular hyperplasia [90.5%(57/63) vs. 55.6%(5/9), P=0.018], and the SUVmax value in adenoma was also higher than that in nodular hyperplasia [11.9(7.8, 16.2) vs. 4.3(3.4, 11.3), P=0.022]. 32 cases were cured after operations, and 37 cases were improved. And 3 cases were not cured. The SUVmax value of lesions in the cured patients was higher than that in the improved patients [15.4(8.1, 22.7) vs. 10.1(6.8, 13.3), P=0.013]. Among 59 cases of PA patients with single adrenal lesions, 50 cases represented positive results of 68Ga-pentixafor PET/CT. 23 cases in 50 positive cases were cured and 27 cases were improved after resection of positive lesions. In the 13 PA patients with multiple adrenal lesions who underwent surgery according to the results of 68Ga-pentixafor PET/CT, 12 patients (92.3%) showed postoperative prognosis in line with preoperative expectations. Conclusions:68Ga-pentixafor PET/CT showed high positive rate in the diagnosis of PA, especially for adenoma.The SUVmax value of the adrenal lesion was correlated with the blood potassium level, the size of the lesion and the postoperative prognosis. In addition, 68Ga-pentixafor PET/CT could effectively guide the surgical decision of PA.

Objective:To comprehensively analyze the expression profile of circular RNA (circRNA) and construct competing endogenous RNA (ceRNA) regulatory networks in tuberous sclerosis complex related renal angiomyolipoma (TSC-RAML).Methods:According to the diagnostic criteria of TSC determined by the international consensus group on tuberous sclerosis in 2012, tumor tissues and paired normal renal tissues of 3 patients with TSC-RAML who were diagnosed in our hospital from January 2017 to January 2019 were collected. The circRNA, miRNA and mRNA of 3 paired samples were detected by circRNA, miRNA chip technology and next generation sequencing respectively, and the differential molecules were determined. Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed based on differential mRNA molecules and host genes of circRNA. Based on differential circRNA, miRNA and mRNA, up-regulated and down-regulated ceRNA regulatory networks were established.Results:A total of 330 up-regulated and 336 down-regulated differential circRNA, 8 up-regulated and 7 down-regulated miRNA, 800 up-regulated and 1130 down-regulated mRNA were screened. Through GO and KEGG enrichment analysis, many pathways including lipid metabolism, focal adhesion and mineral absorption were abnormally altered. Finally, the up-regualted ceRNA network led by hsa_circ_0092022, hsa_circ_0076859 and hsa_circ_0033388 and down-regulated network led by hsa_circ_0000374, hsa_circ_0000141, hsa_circ_0072665, hsa_circ_0009503 and hsa_circ_0000009 were constructed.Conclusions:There were many differentially expressed circRNA between TSC-RAML and paired normal renal tissues. ceRNA regulatory networks may be involved in the occurrence and development of TSC-RAML.

Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.
