Objective To investigate the epidemic characteristics and factors influencing mortality in human immunodeficiency virus (HIV) and hepatitis C virus (HCV)-coinfected patients in heilongjiang region. Methods The clinical data of 712 HIV-infected patients attending our hospital from January 2019 to December 2023 were analyzed retrospectively. The HCV infections were detected by ELISA, and epidemic characteristics of HIV/HCV co-infected patients were analyzed . Co-infected patients (n=116) were classified into survival group (n=90) and death group (n=26) according to the follow-up results, and risk factors for the mortality of HIV/HCV co-infected patients were identified. Results The prevalence of HIV/HCV co-infection was 16.29%, and the prevalence was the highest in 30-50 age group, accounting for 25.47%. There was no significant difference in co-infection rates by gender and marital status (P>0.05). The co-infection rate was the highest among farmers (26.85%) by occupation and among intravenous drug users (61.90%) by route of infection. No statistical difference was found in gender, marital status, and occupational status between survival group and death group (P>0.05), whereas statistical difference was found in age at diagnosis of HIV infection, route of infection, antiretroviral treatment, percentage of CD4+T lymphocytes, and interval between diagnosis and initiation of treatment between two groups (P<0.05). Multivariate Logistic regression analysis denoted that age at diagnosis of HIV infection (OR=1.827, 95% CI: 1.263-2.722), route of infection (OR=1.796, 95% CI: 1.248-2.503), antiretroviral treatment (OR=1.724, 95% CI: 1.202-2.367), percentage of CD4+T lymphocytes (OR=2.536, 95% CI: 1.776-3.739), and the time interval between diagnosis and initiation of treatment (OR=1.953, 95% CI: 1.431-2.952) were all associated with the risk of mortality in co-infected patients (P<0.05). Conclusion The overall prevalence of HIV/HCV co-infection is 16.29% in heilongjiang region . In order to reduce the mortality rate of superinfection , we should focus on patients who are ≥ 40 years old, intravenous drug use , no antiviral therapy , low CD4+ T lymphocyte levels for the first time , and have a long interval between diagnosis and initiation of treatment.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective: To evaluate the clinical efficacy and safety of micro-percutaneous nephrolithotomy (microPCNL) using Needle-perc in the oblique supine-lithotomy position for treating 1—2 cm lower-pole stones (LPSs)，by comparing it with flexible ureteroscopic lithotripsy (FURL)，so as to identify an effective surgical method for LPSs. Methods: We retrospectively analyzed the clinical data of 56 patients with isolated LPSs of 1—2 cm treated in our hospital during Jan.and Dec.2023.Patients were divided into two groups based on the treatment method：FURL (n=31) and microPCNL (n=25).General information and perioperative data were compared between the two groups. Results: All operations were successfully completed.The operation time was shorter in the microPCNL group than in the FURL group \[(46.5±10.1) min vs.(73.5±18.9) min，P<0.001\].Stone-free rate (SFR) was 92.0% in the microPCNL group and 71.0% in the FURL group (P=0.026).There were no significant differences in the average fall of hemoglobin level，serumc creatinine change level，hospitalization time and postoperative fever between the two groups. Conclusion: MicroPCNL in oblique supine-lithotomy position is a safe and effective treatment for 1-2 cm LPSs，with a higher SFR compared to FURL.

OBJECTIVE To explore the effect and mechanism of Buyang huanwu decoction （BYHWD） on mitochondrial dynamics in rats with cerebral ischemia-reperfusion injury （CIRI）. METHODS CIRI rats were randomly divided into CIRI group， low-dose BYHWD （L-BYHWD， intragastric administration of 3.15 mg/kg BYHWD） group， high-dose BYHWD （H-BYHWD， intragastric administration of 12.60 mg/kg BYHWD） group， positive control （intraperitoneal administration of 150 mg/kg Extract of Ginkgo biloba leaves injection） group， H-BYHWD+solvent control （intragastric administration of 12.60 mg/kg BYHWD+ intraperitoneal injection of 20 mg/kg DMSO） group and H-BYHWD+Compound C （intragastric administration of 12.60 mg/kg BYHWD+intraperitoneal injection of 20 mg/kg Compound C） group， with 15 rats in each group. Additionally， 15 rats were assigned to the sham operation group. All rats received the corresponding medications or saline solution via intragastric administration or intraperitoneal injection once daily for 4 consecutive weeks. After the last administration， the cerebral infarct volume of rats was measured； the ultrastructure of mitochondria in endothelial cells in the ischemic penumbra （IP） region was observed； the mitochondrial membrane potential was evaluated； the fluorescence colocalization area ratio of optic atrophy 1 （OPA1） to cluster of differentiation 31 （CD31） in the IP region was detected； the expressions of mitofusin 2 （MFN2）， OPA1， mitochondrial fission 1 protein （Fis1）， and proteins related to the AMP-activated protein kinase （AMPK）/dynamin-related protein 1 （Drp1） pathway in the IP region were determined. RESULTS Compared with the sham operation group， mitochondria in endothelial cells of the IP region in brain tissue of rats in the CIRI group were swollen， mostly spherical， with fractured cristae and severe vacuolation； the percentage of cerebral infarct volume， Fis1 expression level and phosphorylation level of Drp1 were increased significantly （P＜0.05）， while mitochondrial membrane potential in the IP region， fluorescence colocalization area ratio of OPA1 to CD31， the expressions levels of MFN2 and OPA1， and phosphorylation level of AMPK were significantly decreased （P＜0.05）. These indicators were improved in the L-BYHWD group， H-BYHWD group， and positive control group， M025） compared with the CIRI group （P＜0.05）. Compared with the H-BYHWD group and H-BYHWD+solvent control group， the above indicators of rats in the H-BYHWD+Compound C group showed significant reversal（P＜0.05）. There was no statistically significant difference in the above indicators between the H-BYHWD+solvent control group and the H-BYHWD group （P＞0.05）. CONCLUSIONS BYHWD may improve CIRI by activating the AMPK/Drp1 pathway and ameliorating mitochondrial dynamic disorders.

Immune suppression in the tumor microenvironment (TME) is closely related to abnormal glycolysis. Tumor cells gain metabolic advantages and suppress immune responses through the "Warburg effect". Traditional Chinese medicine (TCM) has been shown to regulate key glycolysis enzymes (such as HK2 and PKM2), metabolic signaling pathways (such as PI3K/AKT/mTOR, HIF-1α) and non-coding RNAs at multiple targets, thus synergistically inhibiting lactate accumulation, improving vascular abnormalities, and relieving metabolic inhibition of immune cells. Studies have shown that TCM monomers and formulas can promote immune cell infiltration and functions, improve metabolic microenvironment, and with the assistance by the nano-delivery system, enhance the precision of treatment. However, the dynamic mechanism of the interaction between TCM-regulated glycolysis and TME has not been fully elucidated, for which single-cell sequencing and other technologies provide important technical support to facilitate in-depth analysis and clinical translational research. Future studies should be focused on the synergistic strategy of "metabolic reprogramming-immune activation" to provide new insights into the mechanisms of tumor immunotherapy.

The armadillo repeat containing 5 (ARMC5) gene is part of a family of protein-coding genes that are rich in armadillo repeat sequences, are ubiquitously present in eukaryotes, and mediate interactions between proteins, playing roles in various cellular processes. Current research has demonstrated that reduced expression or absence of the ARMC5 gene in various tumor tissues can lead to uncontrolled cell proliferation, thereby inducing a range of diseases. The ARMC5 gene was initially extensively studied in the context of bilateral macronodular adrenocortical disease (BMAD), with harmful pathogenic variants in ARMC5 identified in approximately 50% of BMAD patients. With advancing research, scientists have discovered that ARMC5 pathogenic variants may also have potential effects on other diseases and could be associated with increased susceptibility to certain cancers. This review aims to present the latest research progress on how the ARMC5 gene plays its role in tumors. It outlines the basic structure of ARMC5 and the regions where it functions, as well as the diseases currently proven to be associated with ARMC5. Moreover, some evidence suggests its relation to embryonic development and the regulation of immune system activity. In conclusion, the ARMC5 gene is a crucial focal point in genetic and medical research. Understanding its function and regulation is of great importance for the development of new therapeutic strategies related to diseases associated with its pathogenic variants.

The transcription factor HOXB13 plays crucial roles in cancer development. HOXB13 is abnormally expressed in most cancers, which makes it a valuable therapeutic target for cancer therapy. The level of HOXB13 differs significantly between healthy and cancer tissues, which indicates that the level of HOXB13 is closely related to carcinogenesis. The regulatory network mediated by HOXB13 in cancer proliferation, metastasis, and invasion has been systematically investigated. Moreover, HOXB13 variants play distinct roles in different cancers and populations. By understanding the molecular mechanisms and mutation features of HOXB13, we provide a comprehensive overview of carcinogenesis networks dependent on HOXB13. Finally, we discuss advancements in anticancer therapy targeting HOXB13 and the roles of HOXB13 in drug resistance to molecular-targeted therapies, which serves as a foundation for developing HOXB13-targeted drugs for clinical diagnosis and cancer therapies.
