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.

Skeletal muscle atrophy refers to a pathological condition characterized by muscle fiber atrophy as well as decreased muscle mass and muscle strength induced by various predisposing factors. It falls under the category of “flaccidity syndrome” in traditional Chinese medicine， and its pathogenesis is mainly associated with disturbed protein homeostasis， mitochondrial dysfunction and oxidative stress injury. Active ingredients of traditional Chinese medicine exerts synergistic regulatory effects via multiple pathways， thus possessing unique advantages in the clinical prevention and treatment of skeletal muscle atrophy. This paper reviews the mechanisms by which active ingredients of traditional Chinese medicine alleviate skeletal muscle atrophy. Existing studies have demonstrated that such active ingredients can ameliorate skeletal muscle atrophy through multiple approaches： regulating protein metabolic balance （geniposide， matrine， schisandrin A， etc.） and oxidative stress （astragaloside Ⅳ， Gastrodia elata polysaccharide， Angelica sinensis polysaccharide， etc.）， improving mitochondrial function （parthenolide， berberine， curcumin， etc.）， facilitating myogenesis and myogenic differentiation （cucurbitacin Ⅱb， saikosaponin A， saikosaponin D， etc.）， suppressing inflammatory response （ursolic acid， triptolide， emodin， etc.）， ameliorating insulin resistance （akebiasaponin D， etc.）. In the future， active ingredients of traditional Chinese medicine are expected to achieve breakthroughs in clinical treatment for skeletal muscle atrophy， providing novel ideas and strategies for the prevention and treatment of degenerative disorders.

Objective:To investigate the current situation of adverse events in hemodialysis nursing in class-A tertiary hospitals in China and analyze their nursing human resources related influencing factors, aiming at provide references for hemodialysis centers to adjust nursing human resources scientifically to reduce the occurrence of nursing adverse events.Methods:A convenient sampling method was used. From August to October 2021, a self-designed questionnaire was used to investigate nursing adverse events in hemodialysis centers of 860 class-A tertiary hospitals during 2020 in China. Multivariate Logistic regression was used to analyze the influencing factors of blood loss, hemodialysis catheter-related blood stream infection (CRBSI) and venous needle dislodgement (VND) in hemodialysis centers.Results:A total of 826 valid questionnaires were received, with an effective response rate of 96.05%(826/860). There were 826 hemodialysis centers covering 31 provinces, municipalities and autonomous regions in China. The establishment period of each center was 24(18, 30) years. There were 45(30, 62) dialysis machines, 180(110, 260) patients and 19(13, 27) registered nurses. Blood loss, hemodialysis CRBSI and VND occurred in 70.94% (586/826), 68.04%(562/826) and 46.97% (388/826) of hemodialysis centers, respectively. Multivariate Logistic regression results showed that the daily treatment shift ( OR=0.730, 95% CI 0.536-0.994), the proportion of nurses with bachelor's degree or above ( OR=1.635, 95% CI 1.142-2.342), and whether nurses worked part-time on peritoneal dialysis treatment ( OR=0.225, 95% CI 0.052-0.965) were the influencing factors for blood loss in hemodialysis centers (all P<0.05). The daily treatment shift ( OR=0.566, 95% CI 0.413-0.777), the number of patients which each nurse was responsible for per shift simultaneously ( OR=0.549, 95% CI 0.400-0.753), proportion of blood purification specialized nurses ( OR=1.661, 95% CI 1.216-2.269), whether nurses worked part-time on CRRT ( OR=0.700, 95% CI 0.511-0.957), the education level of the nursing manager was junior college and below ( OR=3.789, 95% CI 1.576-9.113) and bachelor′s degree ( OR=2.585, 95% CI 1.328-5.033) were the influencing factors for the hemodialysis catheter-associated bloodstream infection in hemodialysis centers (all P<0.05). The number of patients which each nurse ( OR=0.580, 95% CI 0.433-0.777) was responsible for per shift simultaneously was the influencing factor in the occurrence of VND in hemodialysis centers ( P<0.05). Conclusions:The nursing adverse events of blood loss, hemodialysis catheter-associated bloodstream infection and VND were relatively common in hemodialysis centers. The hospital managers should take corresponding measures aiming at the above influencing factors to prevent the occurrence of nursing adverse events and improve the quality and safety of nursing.

Objective:To investigate the risk factors for new adjacent vertebral fracture after percutaneous kyphoplasty (PKP) in patients with osteoporotic vertebral compression fracture (OVCF) and their predictive efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 476 OVCF patients admitted to The Affiliated Wuxi People′s Hospital of Nanjing Medical University from January 2018 to December 2024, including 74 males and 402 females, aged 49-91 years [71(65, 79)years]. Among them, 397 patients underwent single-level PKP, while 79 received multi-level PKP. Surgical segments involved T 6 in 9 patients, T 7 in 9, T 8 in 14, T 9 in 12, T 10 in 9, T 11 in 50, T 12 in 110, L 1 in 173, L 2 in 77, L 3 in 46, L 4 in 31, and L 5 in 13. The patients were divided into adjacent vertebral fracture group ( n=55) and non-adjacent vertebral fracture group ( n=421) according to whether adjacent vertebral fracture was observed during the follow-up. The following data were collected in both groups: gender, age, body mass index (BMI), bone mineral density T-value, underlying diseases (hypertension, diabetes, coronary heart disease), prior cerebral infarction, history of OVCF, long-term glucocorticoid use, thoracolumbar fracture, number of operated vertebrae, cement injection approach (unilateral or bilateral), mean cement dose, postoperative vertebral height restoration rate, postoperative Cobb angle correction, postoperative thoracolumbar kyphosis angle correction, and cement distribution score. Univariate and multivariate Logistic stepwise regression analysis were performed to assess and identify independent risk factors for adjacent vertebral fracture in OVCF patients after PKP. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the risk factors′ predictive performance for adjacent vertebral fracture in OVCF patients after PKP. Results:Univariate analysis revealed significant differences in age, bone mineral density T-value, history of OVCF, long-term glucocorticoid use, number of operated vertebrae, and cement distribution score between the two groups ( P<0.05). The multivariate Logistic stepwise regression analysis showed that the bone mineral density T-value ( OR=0.68, 95% CI 0.48, 0.95, P<0.05) and cement distribution score ( OR=0.61, 95% CI 0.49, 0.76, P<0.01) were significantly correlated with new adjacent vertebral fractures after PKP. The ROC curve analysis showed that bone cement distribution score showed better predictive performance (AUC=0.72, 95% CI 0.64, 0.79), compared with bone mineral density T-value (AUC=0.62, 95% CI 0.54, 0.70), while the combined predictive performance of the two factors was the best (AUC=0.75, 95% CI 0.68, 0.81). Conclusions:Bone mineral density T-value and cement distribution score are independent risk factors for new adjacent vertebral fracture in OVCF patients after PKP. The predictive performance of cement distribution score is proved to be good and can be better in combination with bone mineral density T-value.

Glucagon and insulin are the main regulatory factors for blood glucose and jointly maintain the homeostasis of energy me-tabolism in the body,but the internal mechanism of the mutual regulation and influence between them remains complex and unclear.The liver is one of the key target organs for both insulin and glucagon,playing a crucial role in maintaining the homeostasis of glucose and lipid metabolism.Insulin resistance is often accompanied by abnormal glucose and lipid metabolism in the liver,which may affect the functional activity of glucagon in the liver.There is a glucagon-related feedback loop between the liver and the pancreas,known as the"liver-α-cell axis",which may play a critical role in understanding the metabolic effect of glucagon in the state of insulin resis-tance.In addition to the regulation of glucose homeostasis,the physiological action of glucagon has been extended to lipid and amino acid metabolism.Therefore,abnormal regulation of glucagon metabolism may further lead to the imbalance of glucose,lipid,and amino acid metabolism.This article briefly reviews the regulatory mechanism of glucagon in liver glucose homeostasis,lipid metabolism,and amino acid metabolism in physiological condition and the state of insulin resistance.

Objective To observe the value of 68Ga-DOTA-NOC PET/CT for diagnosing pheochromocytoma(PCC)and paraganglioma(PGL).Methods Thirty-eight patients with suspected or confirmed PCC/PGL who underwent 68 Ga-DOTA-NOC PET/CT were retrospectively enrolled,among them 20 cases underwent 131I-metaiodobenzylguanidine(MIBG)SPECT/CT during the same period.The value of 68Ga-DOTA-NOC PET/CT for diagnosing PCC/PGL at individual and lesion levels were analyzed and compared to the results of 131I-MIBG SPECT/CT.Results Among 38 cases,there were 20 cases of PCC,14 cases of PGL,1 case of adrenocortical carcinoma and 3 cases of benign adrenal hyperplasia.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 68 Ga-DOTA-NOC PET/CT for diagnosing PCC/PGL in all 38 cases was 87.88％(29/33),60.00％(3/5),93.55％(29/31),42.86％(3/7)and 84.21％(32/38),respectively.Totally 188 lesions were detected in 34 cases,with detection rate of 89.95％(188/209).For 20 patients who underwent both 2 kinds examinations,the detection rate of bone,lymph node,liver,lung metastases and the overall lesions of 68Ga-DOTA-NOC PET/CT were all higher than those of 131I-MIBG SPECT/CT(all P＜0.05).No significant difference of diagnostic accuracy of PCC/PGL was found between 68 Ga-DOTA-NOC PET/CT and 131I-MIBG SPECT/CT(P＞0.05).Conclusion The value of 68 Ga-DOTA-NOC PET/CT for diagnosing PCC/PGL was comparable to that of 131I-MIBG SPECT/CT,but the former showed higher detection rate of metastases,hence being helpful to staging and risk stratification of PCC/PGL.
