Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (90Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent 90Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of 90Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (99mTc-MAA) perfusion test and received the 90Y-SIRT; one patient received 90Y-SIRT after the second 99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of 90Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Objective :
To observe the brain tissue injury during hypoxia-ischemia, as well as the pathological changes and the expression of ferroptosis-related factors after the use of Shenfu injection(SFI), and to explore the protective effect of SFI on hypoxic-ischemic brain injury(HIBD) by inhibiting ferroptosis.
Methods :
An animal model of HIBD in SD rats was constructed and intervened with SFI. Pathologic changes in brain tissue were observed by HE staining methods. Nissen staining was used to observe neuron survival. Glutathione Peroxidase 4(GPX4) and Divalent Metal Transporter 1(DMT1) expression were detected in brain tissue by Western blot, immunohistochemistry and immunofluorescence. Reduced Glutathione(GSH), Lactate Dehydrogenase(LDH), Malondialdehyde(MDA), Superoxide Dismutase(SOD) and tissue iron content were determined with the kits. BV-2 microglial cell line(BV2) cells were culturedin vitroand divided into control group(Ctrl group), oxygen-glucose deprivation group(OGD group), iron ferroptosis-inducing group(Erastin group), iron ferroptosis-inhibiting group(Fer-1 group), Shenfu injection group(SFI group), and Erastin+Shenfu injection group(Erastin+SFI group). 2′,7′-Dichlorodihydrofluorescein diacetate(DCFH-DA) reactive oxygen species(ROS) fluorescent probe was used to detect the ROS release level; Immunofluorescence was used to observe intracellular GPX4, DMT1 expression.
Results :
Compared with the Sham group, rats in the HIBD group showed significant neuronal cell damage in brain tissue, decreased GPX4 expression(P<0.01), increased DMT1 expression(P<0.01), decreased GSH and SOD levels(P<0.01), and increased LDH, MDA and tissue iron levels(P<0.05,P<0.05,P<0.01). In contrast, after the intervention of SFI, GPX4 expression was elevated(P<0.01), DMT1 expression decreased(P<0.01), GSH and SOD levels were elevated(P<0.01), and LDH, MDA, and tissue iron levels decreased(P<0.05,P<0.05,P<0.01). The cells experiments showed that compared with the Ctrl group, the OGD group had a significantly higher ROS content and a decrease in the expression of GPX4 fluorescence intensity, and an increase in the fluorescence intensity of DMT1(P<0.01), compared with the OGD group, the ROS content was reduced in the SFI group, while the expression of GPX4 was elevated and the expression of DMT1 was reduced(P<0.01).
Conclusion
Hippocampal and cortical regions are severely damaged after HIBD in neonatal rats, and their brain tissues show decreased expression of GPX4 and increased expression of DMT1. The above suggests that ferroptosis is involved in HIBD brain injury in neonatal rats. In contrast, Shenfu injection has a protective effect on HIBD experimental animal model and BV2 cell injury model by reducing iron aggregation and ROS production.

Background Workers in the cable manufacturing industry are exposed to high-speed machinery and equipment for a long time, coupled with heavy workload, which poses significant risks to their physical health. However, the issue of occupational injuries in this industry has not received enough attention yet. Objective To understand the incidence of occupational injury of workers in cable manufacturing industry and to analyze the influencing factors. Method A basic information questionnaire and an occupational injury questionnaire were developed to investigate the occupational injuries of 1 343 workers in a cable manufacturing enterprise in the past year, and a total of 1 225 valid questionnaires were recovered, with an effective rate of 91.2%. Descriptive statistics were used to characterize the causes, injury locations, injury types, and other characteristics of employees’ occupational injuries. Chi-square test was used to analyze the occupational injury status of groups with different demographic characteristics, occupational characteristics, lifestyles, and interpersonal relationships. Logistic regression was used to analyze the influencing factors of occupational injuries. Result The incidence of occupational injuries among workers in a cable manufacturing enterprise in the past year was 8.6%, which mainly happened in male workers (80.0%) and occurred from May to July in summer (45.7%). The main causes were mechanical injuries (32.4%) and object blows (27.6%). The main sources of damage were machinery and equipment (36.2%) as well as raw materials and products (15.2%). The main injuries were located in upper limbs (53.3%) and lower limbs (22.9%). The main types of injuries were fractures (33.3%) and abrasions/contusions/puncture wounds (19.0%). The results of univariate analysis showed that there were statistically significant variations in the incidence of occupational injuries by gender, overtime, pre-job training, years of service in current position, alcohol consumption, physical exercise per week, and co-worker relationship (P<0.05). The logistic regression model showed that workers who exercised less than twice a week, did not participate in pre-job training, worked overtime, and had fair/poor/very poor colleague relationship had a higher risk of occupational injury, while women had a lower risk of occupational injury. Conclusion The distribution of occupational injury population is mainly male, and the time distribution is mainly from May to July. Gender, physical exercise, pre-job training, overtime, and colleague relationship are the influencing factors of occupational injuries. We should strengthen pre-job training, arrange work hours reasonably, and create a good working atmosphere to reduce the occurrence of occupational injuries.

Ovarian cancer (OC) is one of the most common malignant tumors in women, with the mortality rate being the highest among gynaecological malignant tumors. As the atypical symptoms of OC are difficult to be detected in the early stage, most patients are already in the advanced stage when being diagnosed. As a result, the clinical treatment has limited effects. Currently, the main therapies for OC are surgery and chemotherapy, while their drug resistance and adverse reactions seriously reduce the quality of life of patients. In recent years, traditional Chinese medicine (TCM) has attracted the attention of clinicians and researchers because of its high efficacy, low toxicity, and mild side effects. According to the TCM philosophy of treatment based on syndrome differentiation, the Chinese medicines with multiple targets, wide range, and mild side effects can be screened based on the molecular targets involved in the occurrence and development of OC, which can bring out the unique advantages of TCM in the treatment of OC. Modern studies have shown that the occurrence and development of OC are closely related to the abnormal expression of multiple signaling pathways. The continued abnormal activation of the signal transducer and activator of transcription 3 (STAT3) signaling pathway can lead to abnormal proliferation and malignancy of OC. cause abnormal proliferation and malignant transformation of OC, which is closely related to the development of OC. In addition, studies have shown that Chinese medicine can inhibit the proliferation, angiogenesis, invasion, and metastasis and promote the autophagy and apoptosis of OC cells by regulating the Janus kinase 2 (JAK2)/STAT3 signaling pathway, providing new therapeutic strategies and ideas for the prevention and treatment of OC. This paper summarizes the role of JAK2/STAT3 signaling pathway in OC development by reviewing the relevant articles and reviews the mechanism and research progress of active components and compound prescriptions of Chinese medicine intervening in OC development by regulating the JAK2/STAT3 signaling pathway. This review is expected to provide a systematic reference for clinical research and drug development of OC.

ObjectiveTo explore the effectiveness and safety of Shenlong Dingji Formula (参龙定悸方) on the quality of life in patients with paroxysmal atrial fibrillation (PAF) of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome. MethodsA total of 60 patients with PAF of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome were recruited and randomly divided into a treatment group and a control group, with 30 patients in each group. The control group received standard western medicine treatment, while the treatment group was additionally given Shenlong Dingji Formula orally, one dose per day. Both groups were treated for 4 weeks. The primary outcome measure is the Atrial Fibrillation Effect on Quality of Life (AFEQT) score including scores of four dimensions,i.e. atrial fibrillation-related symptoms, treatment concerns, daily activities, and treatment satisfaction. The secondary outcome measures included the frequency and duration of symptomatic atrial fibrillation episodes and traditional Chinese medicine (TCM) syndrome scores covering symptoms such as palpitations, chest tightness, fatigue, shortness of breath, reluctance to speak, spontaneous sweating, stabbing pain, and insomnia. These indicators were assessed at baseline (before treatment), after 2-week of treatment, after 4-week of treatment, and 4 weeks after the end of treatment (follow-up). Additionally, safety indicators before and after treatment and adverse events occurring during the trial were recorded to evaluate safety. ResultsA total of 56 patients completed the study, with 28 in each group. Primary outcome indicators: 1) the treatment group showed significant improvement in the total score of the AFEQT scale, with significantly higher total scores after 2-week treatment, 4-week treatment, and follow-up compared to the previous time point (P<0.05). In the control group, the AFEQT score significantly increased only after 4-week treatment compared to baseline (P<0.05). In the treatment group, the AFEQT scores after 2-week, 4-week treatment, and during follow-up were all higher than those of the control group at the corresponding time points (P<0.01). 2) In the treatment group, there was no statistically significant difference in the AFEQT treatment satisfaction dimension score during follow-up compared to that after 4-week treatment (P>0.05). However, the scores for all other dimensions at each time point were higher than those at the previous time point (P<0.05). In the control group, the scores for the atrial fibrillation-related symptom dimension were higher after 2-week and 4-week treatment than those of the previous time points (P<0.05). For the treatment satisfaction dimension, significant increases were observed only after 2-week and 4-week treatment compared to baseline (P<0.05). Secondary outcome indicators: 1) In the treatment group, the frequency and duration of symptomatic atrial fibrillation episodes decreased significantly at each time point compared to the previous time point (P<0.05), except for the duration of trial fibrillation at follow-up. In the control group, the frequency of episodes decreased significantly at all time points compared to baseline (P<0.05), while the duration of trial fibrillation showed a significant reduction at follow-up compared to those after 2-week treatment (P<0.05). 2) In the treatment group, TCM syndrome scores significantly reduced after 2-week treatment, 4-week treatment, and during follow-up compared to the previous time point and baseline (P<0.05). In the control group, significant reductions were observed only after 4-week after treatment and during follow-up (P<0.05). The TCM syndrome scores in the treatment group were lower than those in the control group at the same time points (P<0.01). No adverse events occurred during the trial in either group, and safety indicators showed no significant changes after treatment. ConclusionShenlong Dingji Formula effectively improves the quality of life, alleviates TCM syndromes, and reduces the frequency and duration of symptomatic atrial fibrillation in patients with PAF of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome, and demonstrates good safety.

OBJECTIVE To analyze the factors influencing patient satisfaction in the outpatient pharmacy of tertiary maternity and child specialist hospitals in Chongqing, and provide a reference for improving the pharmaceutical management capability of tertiary maternity and child specialist hospitals and enhancing patients’ medical experience. METHODS Utilizing KANO model, a questionnaire was developed and data were analyzed. Key influencing factors were identified through the categorization of requirement attributes, Better values, Worse values, and two-dimensional matrix analysis. The impact of these categorized demand factors on overall satisfaction was further validated through Structural Equation Modeling (SEM). RESULTS Cronbach’s α coefficient for the survey questionnaire was 0.855, exceeding the acceptable threshold of 0.7; Bartlett test for sphericality yielded a value of 5 538.56 with P<0.01, indicating good reliability and validity of the survey results. Through the KANO model’s factor selection process, the top four key factors influencing patient satisfaction in outpatient pharmacies were determined to be: medication pick-up time (r=0.45), pharmacist service attitude (r=0.45), rational medication consultation (r=0.41), self-service calling system (r=0.40), all of which were subsequently validated through SEM. CONCLUSIONS The four factors of medication pick-up time, self-service calling system, pharmacist service attitude, and rational medication consultation significantly influence patient satisfaction in the outpatient pharmacies of tertiary maternity and child hospitals in Chongqing.

The historical development of endogenous wind (内风) is traced with time as the thread, based on the progression of factors such as syndromes, causes of disease, and pathogenesis. It is believed that the concept of wind syndrome originated in The Inner Canon of Yellow Emperor (《黄帝内经》), encompassing both exogenous wind (外风) and endogenous wind syndrome. Over time, exogenous wind syndrome gradually evolved into mild syndromes and severe syndromes, while endogenous wind syndrome emerged from severe syndromes of exogenous wind. Endogenous wind syndrome has both syndrome and pathogenic attributes, and its theoretical system has gradually become more refined. Based on the theories of ancient and modern medical practitioners, and combining the holistic perspectives with Xiang (象) thinking, it is proposed that endogenous wind has both physiological and pathological distinctions. The physiological endogenous wind refers to the liver's moderate dispersing and regulating function, which helps to distribute qi (气), blood, and body fluids, while pathological endogenous wind arises from abnormal liver dispersal. Therefore, in clinical practice, different treatment methods, such as tonifying, unblocking, and warming, can be applied according to the differentiation of deficiency and excess in the pathogenesis.

Objective To construct programmed cell death protein-ligand 1(PD-LI)hi tolerogenic dendritic cell (tol-DC) derived from bone marrow of DA rats and identify its immunological function. Methods DA rat bone marrow cells were extracted, combined with recombinant mouse granulocyte macrophage colony-stimulating factor and recombinant mouse interleukin (IL)-4, and cultured for 6 days in vitro to induce the differentiation of bone marrow cells into immature dendritic cells (imDC). Lipopolysaccharide was used to stimulate cell maturation and cultured for 2 days to collect mature dendritic cells (mDC). PD-L1 lentiviral vector virus stock solution or equivalent dose lentiviral stock solution was added, and PD-L1hitol-DC and Lv-imDC were collected after culture for 2 days. The morphology of PD-L1hitol-DC was observed by inverted phase contrast microscope and transmission electron microscope. Real-time fluorescence quantitative reverse transcription polymerase chain reaction, Western blotting and flow cytometry were used to detect the expression level of specific markers on cell surface. CD8+T cells derived from Lewis rat spleen were co-cultured with imDC, mDC, Lv-imDC and PD-L1hitol-DC, respectively. The levels of inflammatory factors in the supernatant of each group were detected by enzyme-linked immunosorbent assay. The apoptosis of T cells and the differentiation of regulatory T cells (Treg) in each group were analyzed by flow cytometry. Results The morphology of PD-L1hitol-DC modified by PD-L1 gene was consistent with tol-DC characteristics, and the expression levels of CD80, CD86 and major histocompatibility complex (MHC) on the surface were low. After mixed culture with CD8+ T cells, the levels of IL-10 and transforming growth factor (TGF) -β1 in the supernatant of PD-L1hitol-DC group were higher, the levels of tumor necrosis factor (TNF) -α and IL-17A were lower, and the apoptosis of T cells and Treg differentiation were increased. Conclusions Overexpression of PD-L1 through lentiviral vectors may successfully induce the construction of bone-marrow derived PD-L1hitol-DC in DA rats, promote the secretion of anti-inflammatory factors and T cell apoptosis, induce the differentiation of Treg, and inhibit the immune response of allogeneic CD8+T cells, which provides experimental basis for the next organ transplantation immune tolerance study.
