Objective To identify core targets of hepatocellular carcinoma (HCC) by using bioinformatics and specific algorithms, explore their relationships with immune cells, and investigate the causal relationships between immune cells and HCC through Mendelian randomization. Methods Relevant genes associated with the development of HCC were screened using the GEO and TCGA databases. Immune infiltration analysis was conducted using GSVA and CIBERSORT algorithms. A bidirectional Mendelian randomization analysis was then performed to explore the causal relationships between immune cells and HCC. Results A total of 284 HCC-related genes were identified, with 120 genes recognized within the protein interaction network. Immune infiltration analysis revealed significant correlations between key genes and immune cells. Mendelian randomization results indicated that HLA DR on CD33⁺ HLA DR⁺ CD14dim (OR=1.097, 95%CI: 1.002–1.201, P=0.045, P_Bonferroni=0.091) and CD8 on CD28⁺ CD45RA⁺ CD8⁺ T cell (OR=1.123, 95%CI: 1.027–1.228, P=0.011, P_Bonferroni=0.022) were the risk factors for HCC. Conversely, HLA DR⁺⁺ monocyte absolute count was identified as a protective factor for HCC (OR=0.812, 95%CI: 0.702–0.938, P=0.005, P_Bonferroni=0.139). Conclusion The occurrence and development of liver cancer may be related to CDK1, CCNB1, and CDC20, showing a high degree of correlation with Th2 cells, T helper cells, Th17 cells, and DCs. Mendelian randomization shows that HLA DR on CD33⁺HLA DR⁺ CD14dim and CD8 on CD28⁺CD45RA⁺CD8⁺T cells are associated with an increased risk of HCC. The risk of hepatocellular carcinoma is associated with a decrease in the level of HLA DR⁺⁺monocyte absolute count.

Objective:To study the application effect of family integrated ward in maintaining the optimal target pulse oxygen saturation (SpO 2) in premature infants with bronchopulmonary dysplasia (BPD). Methods:This was a retrospective cohort study. Premature infants with BPD admitted to the neonatal intensive care unit of Children's Hospital of Nanjing Medical University from June 2019 to January 2022 were enrolled. Based on whether to stay in family integrated ward and implement family integrated care (FICare), these premature infants were divided into the family ward group and the control group. The ratio of optimal target SpO 2 within 24 h before discharge, the duration of home oxygen therapy, and ratio of readmission due to respiratory disease within 6 months after discharge were analyzed between the two groups. Results:During the study period, a total of 167 premature infants with BPD were admitted, including 101 in the family ward group and 66 in the control group. Compared with the control group, the family ward group showed a higher proportion of achieving the optimal target SpO 2 within 24 h before discharge (58.0% vs. 24.0%), shorter duration for home oxygen therapy (7.0 d vs. 12.0 d), and a lower readmission rate within 6 months after discharge (16.5% vs. 30.2%), which had statistically significant difference (all P<0.05). Further regression analysis showed that participating in the family integrated ward significantly reduced the demand for home oxygen therapy and the duration of home oxygen therapy, but had no significant impact on the readmission rate within 6 months after discharge. Conclusions:Family integrated ward can effectively increase the proportion of achieving the optimal target SpO 2 for premature infants with BPD within 24 h before discharge, reduce the demand for home oxygen therapy, and shorten the time of home oxygen therapy after discharge, which is beneficial for improving the living quality of premature infants with BPD.

ObjectiveTo understand the process and influencing factors affecting the utilization of influenza vaccination services and vaccination decision-making among the elderly in Shanghai, to explore the delivery of influenza vaccination services and the difficulties faced by the health service system, and to provide guidance for optimizing immunization strategies. MethodsBased on the vaccine hesitancy determinants matrix, semi-structured personal interviews were conducted with stakeholders involved in influenza vaccination services in Shanghai from January to February 2024, using a purposive sampling method. Participants were included until thematic saturation was achieved. Interview data were audio-recorded, transcribed, coded, and organized using NVivo 20 software, and analyzed using the thematic framework method. ResultsA total of 25 interviewees were included, including 9 medical staff, 12 elderly people aged 60 and above, and 4 family members. The study found that Shanghai had a well-managed and standardized influenza vaccination service. However, the promotion of vaccine-related information at the grassroots level was passive and limited. Out-of-pocket payment of the vaccine and cultural beliefs of the elderly negatively impacted vaccination rates. Meanwhile, recommendations from family, friends, and medical staff facilitated vaccination, although the impact varied depending on the type of medical staff. Neighborhood committees in townships and streets played a crucial role in delivering vaccination information to the target population. Additionally, the internet, social media, and the COVID-19 vaccine had both positive and negative impacts on influenza vaccination. Strategic optimization of vaccination should prioritize price concessions, enhance publicity strategies, and improve awareness, professionalism, and willingness among medical and healthcare workers to recommend vaccination. ConclusionThe influenza vaccination service in Shanghai is well-managed and standardized. However, it is essential to consider the influence of family and other support systems on the elderly. It is also necessary to enhance the professionalism, service awareness, and willingness to recommend among the medical staff. Furthermore, systematic interventions and publicity efforts should be effectively integrated with social media and the functions of neighborhood committees.

Objective To identify the current research hotspots of global health training, and construct a global health talent training evaluation index system. Methods Publications pertaining to global health talent training evaluation were retrieved in China National Knowledge Infrastructure, Wanfang Database, and Web of Science Core Collection from 2003 to 2022, and keywords were extracted from eligible publications for co-occurrence and cluster analyses using the CiteSpace software. Based on keywords clustering results, a global health talent training evaluation index system was constructed using a context, input, process, and product (CIPP) evaluation model as a theoretical framework. Results A total of 692 Chinese publications and 1 264 English publications were included. Keyword co-occurrence and cluster analyses yielded 10 Chinese and 10 English keyword clusters, and the 10 Chinese keyword clusters included analytic hierarchy process, health diplomacy, personnel structure, crossdiscipline, educational assessment, global health discipline development, training needs, curriculum program, quality evaluation and logistics support, while the English keyword clusters included evidence-based practice, capacity building, global health, quality of life, machine learning, leadership, sub-Saharan Africa, health equity, global health security and global health diplomacy. Based on keyword clustering, a global health talent training evaluation index system was constructed with CIPP as the theoretical framework, which contained 4 primary indicators, 15 secondary indicators and 59 tertiary indicators, and the primary indicators included 4 dimensions of context evaluation, input evaluation, process evaluation and product evaluation. Conclusions A global health talent training evaluation index system has been constructed, which provides an effective evaluation tool and quantitative evidence for future global health talent training.

Stickler syndrome is a hereditary connective tissue disorder, characterized in ocular manifestations by high myopia and vitreous abnormalities. The progression of the disease can lead to giant retinal tear and rhegmatogenous retinal detachment, making it the most common cause of inherited pediatric retinal detachment. Surgical intervention is the primary treatment for retinal detachment associated with Stickler syndrome. However, there are currently no evidence-based management strategies. Patients typically require multiple surgeries, with low reattachment rates and high recurrence rates, emphasizing the importance of prophylactic treatment. Current prophylactic measures include scleral bucking, laser photocoagulation and retinal cryotherapy, but their absolute benefits remain insufficiently supported. This review summarizes recent advances in the prophylaxis and treatment of retinal detachment in Stickler syndrome, aiming to provide new insights and essential references for the prevention and treatment for such conditions.

Clinical data of 124 elderly patients with severe burns who met the inclusion criteria and were admitted to the 12 hospitals from January 2015 to December 2020 were collected, including 4 patients from the Fourth People's Hospital of Dalian, 5 patients from Fujian Medical University Union Hospital, 22 patients from Guangzhou Red Cross Hospital of Jinan University, 5 patients from Heilongjiang Provincial Hospital, 27 patients from the First Affiliated Hospital of Naval Medical University, 9 patients from the First Affiliated Hospital of Nanchang University, 10 patients from Affiliated Hospital of Nantong University, 9 patients from Tongren Hospital of Wuhan University & Wuhan Third Hospital, 12 patients from the 924 th Hospital of PLA, 6 patients from Zhangjiagang First People's Hospital, 4 patients from Taizhou Hospital of Zhejiang Province, and 11 patients from Zhengzhou First People's Hospital. The patients' overall clinical characteristics, such as gender, age, body mass index, total burn area, full-thickness burn area, inhalation injury, causative factors, whether combined with underlying medical diseases, and admission time after injury were recorded. According to the survival outcome within 28 days after injury, the patients were divided into survival group (89 cases) and death group (35 cases). The following data of patients were compared between the two groups, including the basic data and injuries (the same as the overall clinical characteristics ahead); the coagulation indexes within the first 24 hours of injury such as prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen degradation product (FDP), international normalized ratio (INR), and fibrinogen; the blood routine indexes within the first 24 hours of injury such as white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, monocyte count, red blood cell count, hemoglobin, and hematocrit; the organ function indexes within the first 24 hours of injury such as direct bilirubin, total bilirubin, urea, serum creatinine, aspartate aminotransferase, alanine aminotransferase, total protein, albumin, globulin, blood glucose, triglyceride, total cholesterol, alkaline phosphatase, creatine kinase, electrolyte indexes (potassium, sodium, chlorine, calcium, magnesium, and phosphorus in blood), uric acid, myoglobin, and brain natriuretic peptide; the infection and blood gas indexes within the first 24 hours of injury such as procalcitonin, C-reactive protein, pH value, oxygenation index, base excess, and lactate; treatment such as whether conducted with mechanical ventilation, whether conducted with continuous renal replacement therapy, whether conducted with anticoagulation therapy, whether applied with vasoactive drugs, and fluid resuscitation. The analysis was conducted to screen the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns. Results:Among 124 patients, there were 82 males and 42 females, aged 60-97 years, with body mass index of 23.44 (21.09, 25.95) kg/m 2, total burn area of 54.00% (42.00%, 75.00%) total body surface area (TBSA), and full-thickness burn area of 25.00% (10.00%, 40.00%) TBSA. The patients were mainly combined with moderate to severe inhalation injury and caused by flame burns. There were 43 cases with underlying medical diseases. The majority of patients were admitted to the hospital within 8 hours after injury. There were statistically significant differences between patients in the 2 groups in terms of age, total burn area, full-thickness burn area, and inhalation injury, and PT, APTT, D-dimer, FDP, INR, white blood cell count, platelet count, urea, serum creatinine, blood glucose, blood sodium, uric acid, myoglobin, and urine volume within the first 24 hours of injury (with Z values of 2.37, 5.49, 5.26, 5.97, 2.18, 1.95, 2.68, 2.68, 2.51, 2.82, 2.14, 3.40, 5.31, 3.41, 2.35, 3.81, 2.16, and -3.82, respectively, P<0.05); there were statistically significant differences between two groups of patients in whether conducted with mechanical ventilation and whether applied with vasoactive drugs (with χ2 values of 9.44 and 28.50, respectively, P<0.05). Age, total burn area, full-thickness burn area, serum creatinine within the first 24 hours of injury, and APTT within the first 24 hours of injury were the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns (with odds ratios of 1.17, 1.10, 1.10, 1.09, and 1.27, 95% confidence intervals of 1.03-1.40, 1.04-1.21, 1.05-1.19, 1.05-1.17, and 1.07-1.69, respectively, P<0.05). Conclusions:The elderly patients with severe burns had the injuries mainly from flame burns, often accompanied by moderate to severe inhalation injury and enhanced inflammatory response, elevated blood glucose levels, activated fibrinolysis, and impaired organ function in the early stage, which are associated with their prognosis. Age, total burn area, full-thickness burn area, and serum creatinine and APTT within the first 24 hours of injury are the independent risk factors for death within 28 days after injury in this population.

Objective:To investigate the clinical effect of composite surgery in the treatment of chronic common carotid artery occlusion(CCAO).Methods:A retrospective descriptive study was conducted. The clinical data of 7 patients with CCAO admitted to Xuanwu Hospital, Capital Medical University from October 2020 to December 2023 were collected retrospectively. There were 6 males and 1 female. The age was (66.7±10.9) years, ranging from 52 to 83 years. Outpatient or telephone follow-up were conducted after surgery, carotid artery ultrasound or computed tomography angiography were performed at 3 months, 6 months, and 1 year postoperatively to determine vascular patency. The selection of surgical methods and clinical effect were analyzed. Normally distributed measurement data were expressed as mean±standard deviation ( ± s). The measurement data of skewed distribution were expressed by M ( Q1, Q3). Count data were expressed as frequency. Results:All 7 patients were diagnosed with chronic CCAO before operation, 6 on the left and 1 on the right. 3 cases affected the middle and distal segments of the common carotid artery, 1 case affected the proximal segment, and 1 case each affected the middle and distal segments, the remaining case involves the entire common carotid artery. All the procedures were successfully performed, among which 4 cases underwent carotid endarterectomy combined with stent placement, and 3 cases did not receive stent placement after carotid endarterectomy. 1 patient developed neck hematoma after surgery and the remaining patients recovered well after surgery without any complications or deaths. The follow-up time was 13.5(4.0, 20.5) months; 1 patient was lost to follow-up, and 6 patients received effective follow-up. the common carotid artery remained unobstructed in all 6 patients, and there were no transient ischemic attacks or strokes during the follow-up period.Conclusion:Composite surgery is a safe and feasible method that can be used to treat chronic CCAO lesions, and has satisfactory short-term results.

Objective:To investigate whether hydrogen sulfide (H 2S) protects against intestinal ischemia/reperfusion (I/R) injury in rats by regulating c-Jun N-terminal kinase/activator protein-1 (JNK/AP-1) signaling pathway. Methods:Thirty male Wistar rats were divided into sham operated group (Sham group), I/R group, and H 2S donor sodium hydrosulfide (NaHS) intervention group (I/R+NaHS group), with 10 rats in each group. The I/R injury model was established by blocking the superior mesenteric artery with a non-traumatic vascular clip, with 60 minutes of ischemia followed by 120 minutes of reperfusion. In the I/R+NaHS group, 100 μmol/kg of NaHS was injected through the tail vein 10 minutes before reperfusion, followed by continuous infusion of 1.07 mmol·kg -1·h -1 until the end of the 120-minute reperfusion period. Plasma H 2S concentration was measured using a sensitive sulfur electrode. Malondialdehyde (MDA) and superoxide dismutase (SOD) levels in the small intestine tissue were assayed spectrophotometrically. Histological sections of the small intestine were stained with hematoxylin-eosin (HE) staining and scored using the Chiu scoring system to assess the degree of intestinal mucosal injury. Western blotting was used to detect the protein expressions of phosphated-JNK (p-JNK), JNK, AP-1, and BCL-2 in the small intestine tissue. Results:Compared with the Sham group, the I/R group exhibited damage to the lamina propria, hemorrhage, and ulceration, with a significantly higher Chiu score (4.80±0.63 vs. 0.70±0.09, P < 0.01); plasma H 2S concentration and SOD activity in the ileum tissue were significantly reduced [H 2S (μmol/L): 17.29±1.40 vs. 34.62±1.48, SOD (kU/g): 5.38±0.93 vs. 20.56±1.85, both P < 0.01], while MDA level was significantly elevated (μmol/g: 16.06±1.71 vs. 4.80±0.92, P < 0.01); expression of BCL-2 protein in the ileum tissue was significantly down-regulated (BCL-2/β-actin: 0.32±0.06 vs. 0.79±0.05, P < 0.01), while expressions of p-JNK and AP-1 proteins were significantly up-regulated (p-JNK/β-actin: 0.69±0.03 vs. 0.10±0.03, AP-1/β-actin: 0.82±0.02 vs. 0.22±0.02, both P < 0.01). Compared with the I/R group, the I/R+NaHS group showed moderate separation between the epithelial and lamina propria layers, with partial damage to the tips of the villi; the Chiu score was significantly lower (2.90±0.56 vs. 4.80±0.63, P < 0.01); plasma H 2S concentration and SOD activity in the ileum tissue were significantly increased [H 2S (μmol/L): 24.48±1.84 vs. 17.29±1.40, SOD (kU/g): 10.29±1.26 vs. 5.38±0.93, both P < 0.01], while MDA level was significantly reduced (μmol/g: 7.88±1.01 vs. 16.06±1.71, P < 0.01); expression of BCL-2 protein in the ileum tissue was significantly up-regulated (BCL-2/β-actin: 0.44±0.06 vs. 0.32±0.06, P < 0.01), while expressions of p-JNK and AP-1 proteins were significantly down-regulated (p-JNK/β-actin: 0.54±0.05 vs. 0.69±0.03, AP-1/β-actin: 0.66±0.04 vs. 0.82±0.02, both P < 0.01). There was no statistically significant difference in the expression of JNK in the ileum tissue among the Sham group, I/R group, and I/R+NaHS group (JNK/β-actin: 0.63±0.02, 0.66±0.02, 0.64±0.02, respectively, P > 0.05). Conclusion:H 2S exerts a protective effect on intestinal I/R injury in rats by down-regulate the expression of the JNK/AP-1 signaling pathway, as well as reducing oxidative stress levels.

Based on the androgen receptor(AR)/mammalian target of rapamycin(mTOR)signaling pathway, the effects of Xihuang Pills-medicated serum on the proliferation and apoptosis of prostate cancer LNCaP cells were investigated. The drug-containing serum of SD rats was prepared by intragastric administration of Xihuang Pills suspension. The effects of low-, medium-, and high-dose Xihuang Pills-containing serum on the in vitro proliferation of LNCaP cells were detected by cell counting kit-8(CCK-8). Flow cytometry was used to detect the apoptosis level of LNCaP cells after intervention with different concentrations of Xihuang Pills. Protein expression of cleaved cysteinyl aspartate-specific proteinase caspase-3(cleaved caspase-3), B-cell lymphoma-2(Bcl-2), and AR as well as the phosphorylation level of mTOR protein were detected by Western blot. The results showed that compared with the blank serum, the drug-medicated serum could blunt the activity of LNCaP cells. Low-, medium-, and high-dose Xihuang Pills-containing serum could significantly increase the cell apoptosis rate, increase the expression of cleaved caspase-3 protein, decrease the expression of Bcl-2 protein, reduce the expression of AR protein, and down-regulate the level of phosphorylated mTOR(p-mTOR). To study the effect of Xihuang Pills on the growth of LNCaP cells in vivo, different doses of Xihuang Pills were used to intervene in the subcutaneous graft model in nude mice inoculated with LNCaP cells. The expression levels of AR, mTOR, p-mTOR, Bcl-2, and cleaved caspase-3 were detected by Western blot. The results showed that the volumes of subcutaneous graft tumor in the low-dose, medium-dose, and high-dose Xihuang Pills groups significantly decreased compared with that in the model group. The weight of subcutaneous transplanted tumor in each group with drug intervention was significantly lower than that in the model group. Compared with the model group, the low-dose, medium-dose, and high-dose Xihuang Pills groups showed increased cleaved caspase-3 protein expression, decreased Bcl-2 and AR protein expression, and reduced p-mTOR protein expression. Further experiments showed that AR agonist R1881 could block the anti-proliferation and pro-apoptotic effects of Xihuang Pills. The mechanism of Xihuang Pills against prostate cancer is related to the inhibition of the AR/mTOR signaling pathway, inhibition of LNCaP cell proliferation, and induction of apoptosis in cancer cells.
