The inflammatory effect of dietary is strongly related to the development of cancer,therefore,the diet-related inflammatory index was developed as a methodological tool to investigate the relationship between dietary,inflammation and tumors.In this paper,we summarized the results on diet-related inflammatory indices and common cancers of the digestive system based on relevant cancer epidemiological studies.The available epidemiological evidence suggests that pro-inflammatory diet is associated with an increased risk of gastrointestinal malignancies,with the strongest association with colorectal cancer,followed by esophageal and gastric cancers,and then pancreatic cancer,and the least evidence of studies with liver cancer.Among these studies,the level of evidence for esophageal cancer is lower than colorectal cancer,the study of gastric cancer has gender differences and problems in adjusting for confounders,and the study of pancreatic cancer has heterogeneous results.In view of the current research progress and deficiencies,prospective studies or population-based cohort studies,as well as strengthening nutritional epidemiological studies related to common tumors such as liver cancer could be considered in the future.This review is expecting to provide basic information and scientific basis for strengthening the related healthy eating behavior promotion in the prevention and control of digestive system tumors.

Objective:To explore the efficacy and safety of whole-brain low-dose radiotherapy(LDRT)combined with PD-1 inhibitor sin-tilimab and intrathecal pemetrexed(IP)for the treatment of refractory non-small cell lung cancer(NSCLC)with leptomeningeal metastases(LM).Methods:Retrospective analysies were was performed on eight NSCLC patients with LM at the West China Hospital of Sichuan Uni-versity from December 2022 to May 2024.Among the eight patients,there were four were males and four were females,with a median age of 49 years(rangeing,between 34 to 58 years).All patients were treated with whole-brain LDRT combined with immune checkpoint inhibit-or(ICI)and intrathecal chemotherapy regimens,and the therapeutic efficacy was evaluated according to the Response Assessment in Neuro-Oncology(RANO)criteria and the Karnofsky physical status(KPS)score.Adverse reactions were assessed according to the Common Criteria for the Evaluation of Adverse Events(CTCAE version 5.0).Survival analysis was performed using the Kaplan-Meier method.The classification proportion of cerebrospinal fluid subsets before and after treatment was analyzed using by single-cell sequencing,and the differential ana-lysis of gene expression in parallel cells was performed.Results:The best clinical treatment effects in eight patients were were evaluated us-ing the RANO criteria:five patients(62.5%)were evaluated as improved and three(37.5%)as stable.The median KPS score of the eight pa-tients was 30(20-50)before treatment,which was significantly improved to 60(40-90)after treatment(P=0.000 9).The remission rate of neurological symptoms was 100%(8/8)in eight patients.The median neurological progression-free survival(NPFS)was 12 months.The res-ults of single-cell sequencing in CSF of patientss(P1)showed that the proportion of T cells in the patient samples after whole-brain LDRT treatment was significantly higher than that before treatment(6.08%vs.68.87%),and the proportion of tumor cells was significantly lower(12.92%vs.0.6%).The differential analysis of gene expression showed that CCL5 and CXCL13 were significantly upregulated in T cells of CSF after WB-LDRT treatment.Conclusions:The combination of whole-brain LDRT with ICI and IP in the treatment of NSCLC with LM can signific-antly alleviate neurological symptoms,improve quality of life and prolong the NPFS of patients,which is a safe and effective treatment.

Induction of cancer cell ferroptosis has been proposed as a potential treatment in several cancer types. Tumor-associated macrophages (TAMs) play a key role in promoting tumor malignant progression and therapy resistance. However, the roles and mechanisms of TAMs in regulating tumor ferroptosis is still unexplored and remains enigmatic. This study shows ferroptosis inducers has shown therapeutic outcomes in cervical cancer in vitro and in vivo. TAMs have been found to suppress cervical cancer cells ferroptosis. Mechanistically, macrophage-derived miRNA-660-5p packaged into exosomes are transported into cancer cells. In cancer cells, miRNA-660-5p attenuates ALOX15 expression to inhibit ferroptosis. Moreover, the upregulation of miRNA-660-5p in macrophages depends on autocrine IL4/IL13-activated STAT6 pathway. Importantly, in clinical cervical cancer cases, ALOX15 is negatively associated with macrophages infiltration, which also raises the possibility that macrophages reduce ALOX15 levels in cervical cancer. Moreover, both univariate and multivariate Cox analyses show ALOX15 expression is independent prognostic factor and positively associated with good prognosis in cervical cancer. Altogether, this study reveals the potential utility of targeting TAMs in ferroptosis-based treatment and ALOX15 as prognosis indicators for cervical cancer.

Objective: To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases. Methods: A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. Results: The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. Conclusion The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.

Objective: To explore the efficacy of relocation and expansion pharyngoplasty by suspension sutures in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: Seventy-three patients(including 60 males and 13 females) with OSAHS admitted to the department of otorhinolaryngology of our hospital in recent two years were retrospectively analyzed. All the patients had velopharyngeal obstructionevaluated by electronic endoscopic Müller test and were divided into control group (34 cases) and observation group (39 cases). The patients in the control group were performed modified uvulopalatopharyngoplasty, while those in the observation group were performed relocation and expansion pharyngoplasty by suspension sutures.The scores of ESS, AHI and LSaO₂ before and after treatment were collected and compared. Results: The total effective rate of the observation group was 94.87%, which was significantly higher than 79.41% of the control group. The AHI was lower and LSaO₂ value was higher (χ²=-1. 896,-1. 968,P<0.05)in the observation group. The sleeping symptoms and quality of life of the two groups were significantly improved. The ESS score of the observation group was decreased more significantly than that of the control group after treatment, and the difference was statistically significant (χ²=-1.451,P<0.05). The incidence of foreign body sensation in pharynx of the observation group (89.74%) was higher than that of the control group (55.88%), and the postoperative bleeding and postoperative recurrence rate (0.00%, 2.56%) was lower than that of the control group (8.82%, 14.70%)with statistical significance (χ²=4.738,4.249,4.119,P<0.05).The incidence of transient nasopharyngeal reflux in both groups was low and statistically insignificant (χ²=0.629,P>0.05). Conclusions: Preoperative strict screening of indications plays an important role in the selection of palatopharyngeal surgery methods and curative effect. Relocation and expansion pharyngoplasty by suspension sutures can improve the clinical efficacy of OSAHS with better safety and less recurrence.

Objective:To evaluate the efficacy of remimazolam combined with low-dose propofol for sedation during induction of anesthesia.Methods:A total of 228 patients of both sexes, aged 18-64 yr, with body mass index of 19-35 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic cholecystectomy, were divided into 2 groups ( n=114 each) by a random number table method: remimazolam combined with low-dose propofol group (group R) and propofol group (group P). Anesthesia was induced with intravenous injection of sufentanil 0.3 μg/kg, remimazolam 0.3 mg/kg, propofol 0.5 mg/kg and micuronium 0.2 mg/kg in group R, and sufentanil 0.3 μg/kg, propofol 2 mg/kg and micuronium 0.2 mg/kg in group P. Endotracheal intubation was performed when bispectral index value ≤ 50.Before induction (T 0), immediately before intubation (T 1), at 1 min (T 2) and 3 min (T 3) after intubation, mean arterial pressure (MAP) and heart rate (HR) were recorded.The anesthesia induction time and the incidence of hypotension and bradycardia were recorded in the two groups. Results:There was no significant difference in MAP and HR at T 0 between the two groups ( P>0.05). Compared with the value at T 0, MAP in two groups and HR were significantly decreased at T 1-3 in group P ( P<0.01). Compared with group P, the anesthesia induction time was significantly prolonged, and hypotension and bradycardia was decreased in group R ( P<0.05). Conclusion:The combination of remimazolam and low-dose propofol exerts better efficacy for sedation during induction of anesthesia than propofol alone.

Objective:This study was designed to compare inflammatory response, water carriage and gut brain axis in rats with ulcerative colitis (UC) after treatment of three regiments, Huangqintang (HQT), Sishenwan (SSW), and Tongxie Yaofang(TXYF). Method:After approved by Institute of Chinese Materia Medica Ethics Committees in China Academy of Chinese Medical Sciences, UC in rats was induced by using a compound method (trinitrobenzenesulfonic acid plus ethanol). Rats were randomly divided into control, disease, positive control salazosulfapyridine (SASP, 0.5 g·kg^-1), HQT (20 g·kg^-1), SSW(26 g·kg^-1), and TXYF group(22 g·kg^-1). After 5 days of treatment, colonic tissues and the blood were taken for various assays. Damage of colonic tissues was detected by hematoxylin-eosin staining (HE). The distribution of Vasoactine intrestinal (VIP), 5-hydroxytrytamine (5-HT), P-substance (SP) in the blood and serum were detected by enzymelinked immunosorbent assay (ELISA) and immunohistochemistry (IHC), the levels of aquaporin3 (AQP3) and Aquaporin4 (AQP4) in the serum were detected by Western blot, the mRNA expression of Extracellular regulated protein kinases 1 (Erk1) and p38 mitogen-activated protein kinase (p38 MAPK) in the serum were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). Result:The brain-gut peptide results showed that compared with the normal group, the content of 5-HT and VIP in model group were significantly decreased (P<0.01), the content of SP were decreased, but there was no significant statistical difference, compared with the disease group, the content of 5-HT in SASP and TXYF group were clearly increased (P<0.05), the increment of VIP and SP in SASP, HQT, TXYF group were significant (P<0.05). Compared with the normal group, the content of AQP3 in model group were significantly increased(P<0.01), the content of AQP4 were clearly decreased(P<0.01), compared with the disease group, the content of AQP4 in SASP and HQT group were clearly increased (P<0.05), whereas the levels of AQP3 in HQT group were most significant reduced (P<0.01). Compared with the disease group, the expression of Erk1 and p38 were clearly reduced (P<0.01), with the most significant reduce being the expression in HQT group. Conclusion:Three regiments all have therapeutic effects on UC, manifested by improvements of the signs and mental status of UC rats. However, in terms of gut-brain axis disturbance improvement, the therapeutic effect of TXYF was superior than HQT and SSW, whereas in terms of inflammatory response suppression and water carriage accomodation, the therapeutic effect of HQT was superior than SSW and TXYF.
