ObjectiveTo investigate the impact of preoperative frailty on the prognosis of patients with pancreatic cancer who underwent pancreaticoduodenectomy. MethodsA retrospective analysis was conducted on the clinical data of 435 pancreatic cancer patients who underwent pancreaticoduodenectomy at Sun Yat-sen Memorial Hospital of Sun Yat-sen University. Preoperative frailty was assessed using the FRAIL questionnaire. Binary logistics regression analysis was employed to identify factors influencing frailty, and Cox regression analysis was used to evaluate the effect of frailty on survival. According to the demographic characteristics, subgroup analyses were performed on the effect of frailty on prognosis of patients with pancreatic cancer with pancreaticoduodenectomy. ResultsAmong the 435 patients enrolled, 119 (27.4%) exhibited frailty, while 316 (72.6%) did not. Significant differences were observed between the two groups in various clinical parameters, including age, body mass index, American Society of Anesthesiologists (ASA) score, postoperative red blood cell transfusion, postoperative abdominal abscess, serum levels of glycoantigens 199, glycoantigens 125, and alpha fetoprotein, leukocyte count, neutrophil, high density lipoprotein (HDL) level, and pain intensity (P<0.05). Advanced age and an ASA score of Ⅲ were identified as risk factors for frailty, whereas HDL level was a protective factor. Non-frail patients had better postoperative survival times than frail patients. HDL was determined to be an independent protective factor for prognosis, while LDL was an independent risk factor. ConclusionsThis study demonstrates that preoperative frailty is a significant predictor of poor prognosis in pancreatic cancer patients who underwent pancreaticoduodenectomy.These findings suggest that preoperative frailty assessment and targeted interventions to improve nutritional and metabolic status could potentially enhance postoperative survival and quality of life in pancreatic cancer patients.

The annexins(ANX)family is widely present in the cell membrane,cytoplasm or extracellular matrix.As key tumor regulatory molecules,annexins A(ANX A)family can promote or inhibit invasion and metastasis of breast cancer cells by influencing cell membrane and cytoskeleton formation and participating in signaling pathways.ANX A family also plays a role in the apoptosis of breast cancer cells by regulation of pro-apoptotic proteins and cell cycle independent kinases(CDKs)and related pathways.In addition,ANX A family can also promote therapeutic resistance to a large number of drugs.For instance,ANX A1 enhances triple-negative breast cancer resistance by in-ducing epithelial-mesenchymal transformation.ANX A4 induces resistance by forming ANX A4-Fhit complexes and secretion of exosomes containing ANX A6 promotes paclitaxel resistance in breast cancer cells in a YAP1-dependent manner.So ANX A family may be a new target for breast cancer treatment.

OBJECTIVE To explore the effects and potential mechanism of evodiamine on inflammatory response and apoptosis of epithelial cells in asthma model rats. METHODS SD rats were separated into control group, model group, evodiamine low-dose group (10 mg/kg), evodiamine high-dose group (20 mg/kg), dexamethasone group (positive control, 0.5 mg/kg), epidermal growth factor (EGF) group [mitogen-activated protein kinase (MAPK) activator, 10 μg], evodiamine high-dose+EGF group (20 mg/kg evodiamine+10 μg EGF), with 10 rats in each group. Except for the control group, the other groups were sensitized by 3-point injection of 10% ovalbumin(OVA)-aluminium hydroxide mixture and stimulated by inhalation of 2%OVA nebulized liquid to establish an asthma model. The count of inflammatory cells (macrophages and lymphocytes) in bronchoalveolar lavage fluid (BALF) was detected in each group; pathological changes of lung tissue in rats were observed; the apoptosis of airway epithelial cells, the levels of serum inflammatory factors [tumor necrosis factor-α, interleukin-6 (IL-6) and IL-4], the expressions of pathway-related proteins p38 MAPK, phosphorylated p38 MAPK (p-p38 MAPK), signal transduction and transcription activating factor 1 (STAT1)] and apoptosis-related proteins [B cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax)] were all detected in lung tissue. RESULTS Compared with the control group, bronchial mucosal edema, thickening of alveolar septa and extensive infiltration of inflammatory cells were observed in the lung tissue of rats in the model group; the number of inflammatory cells, apoptosis rate of airway epithelial cells, the levels of inflammatory factors, p-38 MAPK/p-38 MAPK, and the protein expressions of Bax and STAT1 were increased significantly; the expressions of Bcl-2 protein and Bcl-2/Bax were reduced significantly (P<0.05). Compared with the model group, the pathological changes in lung tissues were alleviated to varying degrees in evodiamine low-dose and high-dose groups, and dexamethasone groups, and the above indicators were significantly reversed. However, the change trends of corresponding indicators in the EGF group were opposite to the above (P<0.05). EGF could significantly attenuate the effect of high-dose evodiamine on inflammatory response in asthmatic rats (P<0.05). CONCLUSIONS Evodiamine can relieve inflammatory reactions and inhibit the apoptosis of airway epithelial cells in asthmatic rats, the mechanism of which may be associated with inhibiting p38 MAPK/STAT1 signaling pathway.

Objective:To investigate the prevalence of adult skeletal fluorosis caused by drinking tea-type endemic fluorosis in Yushu Tibetan Autonomous Prefecture (hereinafter referred to as Yushu Prefecture), Qinghai Province, and provide scientific basis for prevention and control of the disease.Methods:In August 2021, one village was selected as a survey site in six counties (cities) in Yushu Prefecture, including Nangqian, Chindu, Yushu, Zadoi, Qumarlêb, and Zhiduo. Drinking water samples and 10 brick tea samples were collected from each village to determine the fluoride content in water and brick tea; at least 100 permanent residents aged ≥ 25, who had a habit of drinking brick tea and had lived in the local area for more than 5 years, were selected for X-ray imaging to examine the prevalence of adult skeletal fluorosis.Results:A total of 75 samples of residential drinking water were collected, with a fluoride content of (0.21 ± 0.05) mg/L, ranging from 0.11 to 0.34 mg/L; 60 samples of brick tea, with a fluoride content of (626.70 ± 157.27) mg/kg, ranging from 324.00 to 2 102.00 mg/kg. A total of 1 136 adults were examined, and 318 cases of skeletal fluorosis were diagnosed, with a detection rate of 27.99%. Among them, the detection rates of mild, moderate, and severe skeletal fluorosis were 20.95% (238/1 136), 6.07% (69/1 136), and 0.97% (11/1 136), respectively, with mild symptoms being the main. The detection rates of skeletal fluorosis in males and females were 29.09% (121/416) and 27.36% (197/720), respectively, with no statistically significant difference between the gender (χ 2 = 0.39, P = 0.533). Comparison of the skeletal fluorosis in different gender, the differences were statistically significant (χ 2 = 22.31, P < 0.001). The detection rates of skeletal fluorosis in the age groups of 25 - 35, 36 - 45, 46 - 55, 56 - 65, 66 - 75, and ≥76 years old were 6.86% (7/102), 22.37% (51/228), 24.02% (92/383), 37.44% (73/195), 43.48% (70/161), and 37.31% (25/67), respectively. The differences between the groups were statistically significant (χ 2 = 59.84, P < 0.001). Moreover, there was a statistically significant difference in the composition of skeletal fluorosis among different age groups ( H = 37.66, P < 0.001). The Spearman correlation analysis results showed that the severity of adult skeletal fluorosis was positively correlated with age ( r = 0.34, P < 0.001). Conclusions:There is a certain degree of prevalence of adult skeletal fluorosis in Yushu Prefecture. And as age increases, the condition of skeletal fluorosis becomes more severe.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Small cell lung cancer (SCLC) accounts for about 13%~17% of primary bronchial lung cancer. Due to its rapid growth rate, aggressive behavior, early metastasis and poor prognosis, about 70% of patients were diagnosed with extensive-stage (ES) disease. Although most ES-SCLC patients are sensitive to initial chemotherapy, local recurrence and distant metastasis develop in the short term. Immunotherapy has brought the dawn to overcome it. At present, immune checkpoint inhibitor combined with chemotherapy has become an important strategy as first-line therapy for ES-SCLC. Nevertheless, patients are still at a high risk of chest lesion recurrence after initial systemic therapy. Whether the addition of thoracic consolidation radiotherapy (TRT) can reduce chest lesion recurrence rate remains to be determined. In this review, we summarized the latest research progress in the mode of first-line chemotherapy combined with immunotherapy followed by TRT in ES-SCLC, aiming to provide reference for clinical practice.

Objective:To analyze the proportion of patients with acute primary angle-closure glaucoma (PACG) after the outbreak of coronavirus disease 2019 (COVID-19) in patients undergoing glaucoma surgery and the factors influencing morbidity.Methods:A cross-sectional study was performed.The cluster sampling method was used to collect 141 glaucoma patients hospitalized for glaucoma surgery after the outbreak of COVID-19 in Xuzhou First People's Hospital from December 16, 2022, to January 16, 2023, and 231 glaucoma patients hospitalized for surgery in the same 1-month period from 2019 to 2020, 2020 to 2021, 2021 to 2022 through the hospital information system.Ninety-two eyes of 92 patients with acute PACG after the outbreak were selected as a study group, and 21 eyes of 21 patients with acute PACG hospitalized during the same 1-month period from 2021 to 2022 were selected as a control group.The proportion of patients with different types of glaucoma during the observation period was analyzed.The proportion of patients with acute PACG and the clinical characteristics of acute PACG were analyzed, including age, sex, visual acuity, intraocular pressure (IOP), and anterior chamber angle status.Epidemiological data such as the use of anti-cold medications, and changes in living habits and moods (including daily water intake and anxiety) of patients after COVID-19 infection were obtained by telephone follow-up.Anxiety levels of patients in the study group were assessed using the Hospital Depression and Anxiety Scale (HADS).The triggering factors of acute PACG attack after the COVID-19 outbreak were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xuzhou First People's Hospital (No.xyyll[2023]114).Written informed consent was obtained from each subject.Results:The proportion of acute PACG patients in Xuzhou First People's Hospital within one month after the outbreak in 2022 to 2023 increased significantly compared with the same period in 2021 to 2022, 2020 to 2021 and 2019 to 2020, and the differences were statistically significant ( χ2=31.066, 33.331, 20.804; all at P<0.001).There was no statistical significance in the distribution of the number of eyes with different grades of visual acuity, IOP, the number of eyes with IOP ≥30 mmHg (1 mmHg=0.133 kPa), and the distribution of the number of eyes with different anterior chamber angles between the two groups (all at P>0.05).Patients in the control group had no history of COVID-19 infection or use of cold medicines at disease onset.During disease onset, all 92 (100%) patients in the study group had positive COVID-19 nucleic acid test results, of which 57 (61.96%) patients had a history of oral anti-cold medication use.During the same period, 49 (100%) hospitalized patients with other types of glaucoma had positive COVID-19 nucleic acid test results, of which 20 (40.82%) patients had a history of oral cold medication.There was a statistically significant difference in the proportion of patients taking oral cold drugs between acute PACG and other types of glaucoma in the study group ( χ2=5.764, P=0.016).During the outbreak of COVID-19, the study group reported that the daily water intake had increased to varying degrees than before.In the study group, 76 patients had anxiety, accounting for 82.6%.Multiple linear regression analysis showed that IOP=19.052+ 0.009×daily water intake+ 0.858×HADS score ( R2=0.780), and the standardized coefficients of daily water intake and HADS score were 0.542 and 0.452, respectively.Daily water intake had a greater effect on IOP than HADS score. Conclusions:The proportion of acute PACG patients among hospitalized surgical glaucoma patients increased significantly after the COVID-19 outbreak, which is related to risk factors such as oral anti-cold medications containing vasoconstrictors or antihistamines, increased daily water intake, anxiety and other lifestyle, and mood changes.

Objective As important components in the microenvironment of hepatocellular carcinoma(HCC),hepatic stellate cells(HSCs)and hydrogen sulfide(H2S)participate in various biological processes that regulate the development and progression of HCC.Through the co-culture of HSCs and HCC cells,this article aims to investigate the role and mechanism of HSCs in regulating the apoptosis of HCC cells by secreting H2S.Methods The HSC cell line(LX-2)and HCC cell lines(HepG2 and PLC/PRF/5)were used for experiment.RT-qPCR and Western Blot(WB)were used to measure the mRNA and protein expression levels of cystathionine γ-lyase(CSE),a key synthase for H2S;ELISA was used to measure the concentration of H2S in supernatant;next-generation sequencing,cell immunofluorescence assay,chromatin immunoprecipitation(ChIP),and WB were used to measure the JNK/JunB-TNFSF14 signaling pathway genes,binding sites,and related proteins after HepG2 cells were treated by H2S.LX-2 cells were co-cultured with HepG2 or PLC/PRF/5 cells in a Transwell chamber;CCK-8 assay and flow cytometry were used to measure the viability and apoptosis of HCC cells,and WB was used to measure the H2S-TNFSF14 signaling pathway-related proteins.All cell experiments were repeated three times.The independent-samples t test was used for comparison of continuous data between two groups;a one-way analysis of variance or the analysis of variance with repeated measures was used for comparison between multiple groups,and the Dunnett-t test was used for further comparison between two groups.Results LX-2 cells synthesized H2S mainly through CSE,and the concentration of H2S in supernatant of LX-2 cells gradually increased over time(22.89±0.08 pg/mL vs 28.29±0.15 pg/mL vs 36.19±1.90 pg/mL,F=79.63,P<0.05).In LX-2 cells,the mRNA expression level of CSE was significantly higher than that of CBS and MPST(1.008±0.13 vs 0.320±0.014 vs 0.05±0.02,F=80.84,P<0.05).When CSE was inhibited by PPG,the concentration of H2S decreased with the increase in the concentration of PPG(P<0.05).LX-2 cells were co-cultured with HepG2 or PLC/PRF/5 cells,and over the time of culture,there were significant reductions in the viability of HepG2 cells(87.48%±0.82%vs 70.48%±0.641%vs 52.89%±0.57%vs 45.20%±0.69%,F=1 517.13,P<0.001)and PLC/PRF/5 cells(92.41%±0.48%vs 74.10%±0.73%vs 53.70%±0.60%vs 44.00%±0.27%,F=2626.21,P<0.001)and significant increases in the apoptosis of HepG2 cells(12.88%±0.64%vs 15.5%±0.16%vs 18.43%±0.37%vs 13.01%±0.58%,F=142.15,P<0.001)and PLC/PRF/5 cells(8.51±0.05 vs 12.80±0.33 vs 15.59±0.21 vs 10.72±0.30,F=676.40,P<0.001),with the most significant changes on day 3.Next-generation sequencing showed that endogenous H2S and NaHS(endogenous H2S donor)were involved in regulating the expression of various genes in HepG2 cells.By releasing H2S,NaHS and LX2 activated the JNK/JunB signaling pathway and upregulated the expression of the apoptosis gene TNFSF14 in HCC cells,with increased binding between p-JunB and the transcriptional regulatory regions of the TNFSF14 gene.Conclusion In the microenvironment of HCC,HSCs activate the JNK/JunB signaling pathway in HCC cells through the signal molecules CSE/H2S,and there is an increase in the expression of TNFSF14,thereby promoting the apoptosis of HCC cells.
