Vascular endothelial growth factor (VEGF) inhibitors are drugs that target and inhibit tumor angiogenesis. By blocking the signaling pathway of VEGF and its receptor, they suppress tumor proliferation and play a crucial role in tumor treatment. However, their side effects, such as hypertension, proteinuria, hand-foot skin reactions, and myelosuppression, during treatment seriously affect patients' treatment compliance and quality of life. The development of intervention strategies for the side effects of VEGF inhibitors is of great importance for tumor treatment. This article reviews the clinical characteristics and toxic mechanisms of common side effects caused by VEGF inhibitors during tumor treatment and summarizes intervention strategies that combine traditional Chinese and Western medicines. Drug dosages were precisely monitored and adjusted to achieve antitumor treatment. Patients' discomfort symptoms are improved through prescriptions that act by tonifying qi and promoting blood circulation, strengthening the spleen, and tonifying the kidney. The combination of traditional Chinese and Western medicines is used to treat patients, thus providing a safe and effective treatment plan for patients with cancer.

Objective To explore the expression and clinical significance of serum microRNA(miR)-503 and miR-186 in patients with vascular dementia(VD)caused by ischemic stroke.Methods A total of 126 pa-tients with ischemic stroke admitted to this hospital from December 2020 to December 2022 were selected as the observation group,and were divided into VD group(35 cases)and non-VD group(91 cases)according to the results of follow-up visits 3 months after treatment.Another 61 healthy subjects who underwent physical examination in the same period were selected as the health group.The expression levels of serum miR-503 and miR-186 were detected by quantitative fluorescence PCR(qPCR),and the general data of VD group and non-VD group were compared.Logistic regression model was used to analyze the factors affecting the occurrence of VD in patients with ischemic stroke,and ROC curve was drawn to analyze the efficacy of serum miR-503 and miR-186 in predicting the occurrence of VD after ischemic stroke.Results Serum miR-503 and miR-186 ex-pression levels in non-VD group and VD group were higher than those in healthy group(P＜0.05),and serum miR-503 and miR-186 expression levels in VD group were higher than those in non-VD group(P＜0.05).Pearson analysis showed that there was a significant positive correlation between serum miR-503 and miR-186 expression level in patients with VD caused by ischemic stroke(r=0.462,P＜0.001).There were statistical-ly significant differences in hypertension,NIHSS score,smoking proportion and mRS score between the two groups(P＜0.05).Smoking,hypertension,NIHSS score,mRS score,serum miR-503 expression level and ser-um miR-186 expression level were risk factors for VD in patients with ischemic stroke(P＜0.05).The area under the curve(AUC)of serum miR-503 and miR-186 combined to predict VD in ischemic stroke patients was 0.948,and the sensitivity and specificity were 85.70％and 92.30％,respectively.The prediction efficacy was better than that of serum miR-503 and miR-186 alone(Z=2.784,2.275,P=0.005,0.023).Conclusion Serum miR-503 and miR-186 are highly expressed in patients with VD caused by ischemic stroke,and which have predictive value for the occurrence of VD in patients with ischemic stroke.

Long non-coding RNAs(lncRNAs)regulate gene expression at the transcriptional,post-transcription-al,or epigenetic levels,and play crucial roles in tumor cell proliferation,invasion,apoptosis,and metabolism.With ongoing research,an increasing number of human microproteins encoded by lncRNAs have been discovered,although their complete functional characterization remains to be explored.This article reviews the research progress on the func-tions and partial mechanisms of the small integral membrane protein(SMIM)family encoded by lncRNAs in tumor ini-tiation and progression.

Objective:To explore the correlations of sleep quality and architecture with heart rate variability (HRV) in patients with stenoses of vertebrobasilar artery system and internal carotid artery system.Methods:A retrospective study was performed; 72 patients with stenosis or occlusion of the head and neck arteries (not resulting in cerebral infarction) admitted to Department of Neurology, Second Affiliated Hospital of Zhengzhou University from June 2023 to June 2024 were chosen, including 33 patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system (VB group) and 39 patients with moderate-to-severe stenosis or occlusion of the internal carotid artery system (ICA group). Pittsburgh sleep quality index (PSQI) and polysomnography (PSG) were used to evaluate the sleep quality and architecture, respectively; and 24-hour ambulatory electrocardiogram was used to assess the HRV. Differences in PSQI score, PSG and HRV parameters between the two groups were compared; partial correlation analysis was used to explore the correlations of HRV parameters with PSQI scores and PSG parameters; multivariate linear regression was used to analyze the independent influencing factors for HRV.Results:(1) Compared with the ICA group, the VB group exhibited significantly higher PSQI scores, spontaneous arousal index (SAI), ratio of time of stage 1 non-rapid eye movement sleep/total sleep time (T N1/T t), and apnea-hypopnea index (AHI), while significantly lower ratio of time of rapid eye movement sleep/total sleep time (T R/T t), spindle wave density in stage 2 non-rapid eye movement sleep (N2), lowest blood oxygen saturation, standard deviation of normal to normal intervals (SDNN) of all sinus beats, low-frequency power (LF), and high-frequency power (HF, P<0.05). (2) In both VB group and ICA group, SDNN was negatively correlated with PSQI score ( r=-0.461, P=0.020; r=-0.378, P=0.036). In the VB group, SDNN was negatively correlated with T N1/T t ( r=-0.467, P=0.019) and SAI ( r=-0.551, P=0.004), and positively correlated with ratio of time of stage 3 non-rapid eye movement sleep/total sleep time (T N3/T t, r=0.686, P<0.001) and spindle wave density in N2 ( r=0.518, P=0.008); LF and HF were negatively correlated with SAI ( r=-0.481, P=0.015; r=-0.564, P=0.003). In the ICA group, HF was negatively correlated with spindle wave density in N2 ( r=-0.369; P=0.041). (3) Multivariate linear regression results indicated that T N3/T t (β=0.348, P=0.018), SAI (β=-0.330, P=0.018), and spindle wave density in N2 (β=0.286, P=0.013) were independent influencing factors for Ln_SDNN in patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system. Conclusion:Patients with stenosis or occlusion of the vertebrobasilar system exhibit poorer subjective sleep quality, increased light sleep, heightened arousal, and reduced sleep stability compared with those with stenosis or occlusion of the internal carotid artery system, which may be caused by the imbalance of autonomic nerve function.

Objective:To explore the clinical characteristics of patients with brucellosis complicated with epididymo-orchitis (Brucellar epididymo-orchitis, BEO), so as to provide reference for clinical diagnosis and treatment of BEO.Methods:General and clinical data of 293 male patients with acute brucellosis admitted to the Beidahuang Industry Group General Hospital from January 2023 to December 2024 were retrospectively collected. They were divided into a BEO group (30 cases) and a non-BEO group (263 cases) based on the presence or absence of epididymo-orchitis. Epidemic characteristics, clinical manifestations and laboratory examination results were compared and analyzed.Results:Among 293 male patients with acute brucellosis, the incidence of BEO was 10.24% (30/293). Their age was mainly concentrated in 45 - < 60 years old (53.33%, 16/30), and occupation was mostly farmers (63.33%, 19/30). There were no statistically significant differences in the distribution of age, occupation, exposure history and onset season between the BEO group and the non-BEO group ( P > 0.05). The distribution of abdominal pain and urinary frequency/urgency/pain symptoms was compared, and the differences were statistically significant ( P < 0.05). White blood cell count (WBC), neutrophil count (NEUT), and C-reactive protein (CRP) levels in the BEO group were higher than those in the non-BEO group ( P < 0.05), while the levels of cytokines interleukin (IL)-6 and interferon-γ (IFN-γ) were lower than those in the non-BEO group ( P < 0.05). After 6 - 8 weeks of hospitalization, the levels of WBC, NEUT, CRP, albumin, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, alkaline phosphatase, α-hydroxybutyrate dehydrogenase, lactate dehydrogenase, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor-α, and IFN-γ in patients of the BEO group were significantly different from before treatment ( P < 0.05). Twenty-eight patients were cured, 1 patient underwent orchiectomy, and 1 patient experienced recurrence. Conclusions:Middle-aged male patients with brucellosis are more prone to BEO. Clinical manifestations and laboratory tests have certain diagnostic value for BEO. Suspected BEO patients should be diagnosed and treated as early as possible to reduce the occurrence of adverse prognosis.

Objective:To learn about the clinical characteristics of patients with neurobrucellosis (NB) and provide references for clinical diagnosis and treatment of NB.Methods:The clinical data of 22 NB patients diagnosed and treated at Beidahuang Industry Group General Hospital from January 2018 to November 2024 and 178 healthy individuals undergoing physical examinations during the same period were retrospectively collected. The epidemiological characteristics, clinical manifestations, laboratory tests, treatment and prognosis of NB patients were analyzed.Results:Among the 22 NB patients, 12 were males (54.55%) and 10 were females (45.45%). The age was (51.77 ± 12.75) years old, ranging from 27 to 80 years old. Most of the patients were farmers (95.45%, 21/22), and 16 cases (72.73%) had contacted with cattle/sheep. The onset seasons were mainly in summer (40.91%, 9/22) and spring (31.82%, 7/22). Among all NB patients, there were 10 cases of encephalitis/meningoencephalitis, 9 cases of myelitis, and 3 cases of meningitis. The general symptoms were mainly fever (68.18%, 15/22), the neurological symptoms were mainly nausea and vomiting (36.36%, 8/22), and the physical signs were mainly muscle weakness (50.00%, 11/22) and pathological signs (45.45%, 10/22). The laboratory test results showed that the levels of hemoglobin, hematocrit, C-reactive protein, total protein, albumin, γ-glutamyl transpeptidase, α-hydroxybutyric acid dehydrogenase, lactate dehydrogenase, and glutathione reductase in NB patients were significantly different from those in healthy individuals ( P < 0.001). Brain magnetic resonance imaging revealed ischemic changes in 5 cases (22.73%), abnormal brain signals in 2 cases (9.09%), and demyelinating lesions in white matter in 1 case (4.55%). After treatment, 18 NB patients were followed up and showed good prognosis, with only 2 cases exhibiting varying degrees of sequelae (walking disorders or memory impairment). Conclusions:The clinical manifestations of NB patients are diverse. A comprehensive judgment should be made by combining epidemiological characteristics, clinical manifestations, laboratory tests and imaging examinations.

Objective:To explore the relapse-related genes and their clinicopathological connections of diffuse large B cell lymphoma (DLBCL).Methods:Targeted panel sequencing was conducted on 32 eligible DLBCL samples; the patients were diagnosed, treated, and went into complete remission at the First Affiliated Hospital of Nanjing Medical University from January 2015 to December 2019, including 14 cases with recurrence (relapsed group) and 18 cases with long-term complete remission of over five years (remission group). Clinical and pathological data were further reviewed. Fisher′s exact test was employed to compare the differences in clinicopathological characteristics and mutation patterns between the two groups.Results:Among the 32 patients, there were 18 males and 14 females, with a male to female ratio of 1.3∶1.0 and a median age of 53 (45.5, 67.0) years. In the relapsed group, PIM1 (11/14), KMT2D (7/14), PRDM1 (6/14), MYD88 (6/14), DTX1 (6/14) emerged as the most frequently mutated genes. In the remission group, while recurrent PIM1, KMT2D and MYD88 mutations were also observed, the TP53 gene exhibited the highest mutation frequency (6/18). Compared to the remission group, relapsed group showed elevated mutation frequencies of PIM1 ( P=0.013) and FAT4 ( P=0.010), alongside a reduced incidence of TP53 mutations. In all 32 patients, DLBCL with CD79B, CCND3, DTX1, KMT2D and PRDM1 mutations demonstrated a propensity towards advanced clinicopathologic stage. Conclusions:Relapsed DLBCL has distinctive clinicopathological and genetic features. PIM1 and FAT4 may be served as potential biomarkers for screening relapsed DLBCL-NOS and as targets for novel therapeutic strategies.

Objective:To explore the clinical and pathological features of EBV-positive diffuse large B cell lymphoma (EBV +DLBCL) and to analyze the prognostic significance of CD30 expression in this entity. Methods:A retrospective analysis was conducted from 34 cases of EBV +DLBCL and 198 cases of EBV -DLBCL diagnosed and treated at the First Affiliated Hospital of Nanjing Medical University, from January 2017 to June 2023. Based on CD30 expression, 34 patients with EBV +DLBCL were categorized into CD30-positive and CD30-negative groups. Fisher exact test and Kaplan-Meier survival curves were employed to analyze the relationship between CD30 expression and clinicopathological parameters as well as its prognostic implications. Chi-square tests were used to compare the clinicopathological features between EBV +DLBCL and EBV -DLBCL. Results:There were 19 males and 15 females with a median age of 69.5 (15-83) years in the EBV +DLBCL group. Compared with EBV -DLBCL, EBV +DLBCL was more likely to present with clinical features such as B symptoms ( χ2=23.818, P<0.001), Ann Arbor stage Ⅲ-Ⅳ ( χ2=8.540, P=0.003), ECOG (Eastern Cooperative Oncology Group Performance Status) score 2-4 ( χ2=6.722, P=0.010), IPI score 3-5 ( χ2=9.953, P=0.002), and involvement of more than one extranodal site ( χ2=6.825, P=0.009). Additionally, EBV +DLBCL exhibited higher frequencies of elevated LDH ( χ2=4.307, P=0.038), CRP ( χ2=5.596, P=0.018), and β2-MG ( χ2=7.008, P=0.008) levels. Histopathologically, EBV +DLBCL was more commonly of the non-GCB subtype ( χ2=12.421, P<0.001), with higher frequencies of CD30-positive ( χ2=62.706, P<0.001),CD10-negative ( χ2=8.687, P=0.003),bcl-6-negative ( χ2=11.123, P<0.001), and bcl-2-negative ( χ2=22.779, P=0.003) expression. Using 20% as the positive threshold for CD30, the CD30-positive group had a higher proliferation index ( P=0.045). No significant differences were observed in overall survival between the two groups. Conclusions:EBV +DLBCL is more prevalent in the elderly and often exhibits aggressive clinical features. The expression of CD30 is not associated with the overall prognosis of EBV +DLBCL.
