BackgroundRumination can play a certain degree role of psychological adjustment in cancer patients. Previous studies have focused on studying the level of rumination in a single type of cancer patient， but there is a lack of comprehensive investigation and influencing factor research on rumination levels in different types of cancer patients. ObjectiveTo explore the level of rumination and its influencing factors among middle-advanced cancer inpatients， so as to provide certain guidance for targeted psychological care in clinical practice. MethodsFrom January 2021 to December 2022， a systematic sampling technique was used to recruit 346 patients with TNM stage III or above tumors hospitalized in Nuclear Industry 416 Hospital， Chengdu Sixth People's Hospital and the First People's Hospital of Yibin. All individuals were assessed using Perceived Social Support Scale （PSSS） and the Chinese version of Event-Related Ruminant Inventory （C-ERRI）， and Logistic regression analysis was utilized to identify the influencing factors of rumination. ResultsIn terms of C-ERRI， patients scored （15.59±5.61） on intrusive rumination and （14.59±5.43） on deliberate rumination. Education levels of junior high school/high school/vocational training school （OR=0.817， P<0.01） and junior college and above （OR=0.579， P<0.05） were the protective factors of intrusive rumination， whereas annual personal incomes of <10 000 yuan （OR=4.918， P<0.01） or 10 000~50 000 yuan （OR=2.076， P<0.01） and low （OR=6.882， P<0.01） or middle （OR=3.114， P<0.01） level of social support were the risk factors of intrusive rumination. For deliberate rumination， education levels of junior high school/high school/vocational training school （OR=0.574， P<0.01） and junior college and above （OR=0.449， P<0.05） were the protective factors， and low （OR=1.391， P<0.01） or middle （OR=1.161， P<0.05） levels of social support were the risk factors. ConclusionThe level of intrusive rumination of inpatients with middle-advanced cancer is related to education level， economic status and social support， furthermore， the level of deliberate rumination is related to the educational level and social support. ［Funded by Medical Research Project of Chengdu Health Commission （ number， 2020119）］

OBJECTIVE To investigate the intervention effect of Dabufei decoction on acute lung injury in rats with high altitude hypoxia by regulating the expression of the HIF-1α/NLRP3 signaling pathway and related molecules. METHODS Sixty SPF SD rats were randomly divided into blank group, model group, positive drug group, Dabufei decoction high-dose, medium-dose, and low-dose groups with 10 rats in each group. After 3 d of adaptation to feeding, the rats in the blank group and model group were given the same amount of normal saline by gavage, and the rats in Dabufei decoction high-dose, medium-dose, and low-dose groups were given gavage for 14 d, respectively. The positive drug group was given dexamethasone by intraperitoneal injection for three consecutive days before entering the chamber. Except for the blank group, the rats in each group were exposed to hypoxia in the experimental animal low-pressure simulation chamber from the 15th day for three consecutive days. At the end of the experiment, the wet to dry ratio(W/D) of the rat lung tissue was detected. The morphology of lung tissue was observed by HE staining. ELISA detected the levels of IL-1β and IL-18 in serum. Western blotting and RT-qPCR were used to detect the protein and mRNA expressions of HIF-1α, NLRP3, GSDMD, and caspase-1 in the lung tissue of rats. RESULTS The W/D value showed that compared with the blank group, the W/D of the model group was significantly increased(P<0.01). Compared with the model group, the W/D of rats in the positive drug group, Dabufei decoction high-dose group, medium-dose, and low-dose groups was significantly decreased(P<0.01 or P<0.05). HE results showed that compared with the blank group, alveolar septum thickening, pulmonary interstitial congestion, edema, inflammatory cell infiltration, and a small amount of exudation in the alveolar cavity were seen in the lung tissue of the model group. Compared with the model group, the thickening of alveolar walls in the positive drug group, Dabufei decoction high-dose group, medium-dose, and low-dose groups were reduced, and the pulmonary interstitial congestion, edema, and inflammatory cell infiltration were significantly reduced. ELISA results showed that IL-1β and IL-18 in rat serum were significantly higher in the model group than in the blank group(P<0.01). Compared with the model group, the levels of IL-1β and IL-18 in the serum of the rats in the positive drug group, Dabufei decoction high-dose group, medium-dose, and low-dose groups were significantly decreased(P<0.05 or P<0.01). Moreover, the results of Western blotting and RT-qPCR showed that compared with the blank group, the relative protein and mRNA expressions of HIF-1α, NLRP3, GSDMD, and caspase-1 in the lung tissue of the model group were significantly increased(P<0.01). Compared with the model group, the relative protein and mRNA of HIF-1α, NLRP3, caspase-1 and GSDMD in the positive drug group and Dabufei decoction high-dose group were significantly decreased(P<0.05 or P<0.01), the relative protein of HIF-1α, NLRP3, caspase-1 and GSDMD in Dabufei decoction medium-dose group were significantly decreased and HIF-1α, caspase-1 mRNA were significantly decreased(P<0.05), the relative protein of HIF-1α and GSDMD in the low-dose group was decreased(P<0.05). The positive drug group and Dabufei decoction high-dose group had the more significant effect. CONCLUSION Dabufei decoction can regulate the HIF-1α/NLRP3 signaling pathway, inhibit pyroptosis and reduce inflammation, and has a certain protective effect on acute lung injury in rats with high altitude hypoxia.

ObjectiveTo investigate the protective effect of Guiqi Baizhu prescription combined with oxaliplatin on the intestinal barrier of tumor-bearing mice with gastric cancer by regulating downstream aquaporin 3 （AQP3） and aquaporin 4 （AQP4） through the vasoactive intestinal peptide （VIP）/cyclic adenosine monophosphate （cAMP）/protein kinase A （PKA） signaling pathway. MethodThe gastric cancer cell lines MFC with a density of 1×10⁷/mL were prepared into cell suspension. The tumor-bearing mouse model of gastric cancer was established by inoculating 0.2 mL cell suspension under the right axilla of mice. After successful modeling， mice were randomly divided into 5 groups， namely， model group， oxaliplatin group （10 mg·kg^-1）， and high， medium， and low-dose oxaliplatin + Guiqi Baizhu prescription groups （17.68， 8.84， 4.42 g·kg^-1）， with 10 mice in each group， and the remaining 10 mice were set as a blank group. Mice in each group were treated with Chinese medicine， oxaliplatin， or normal saline by gavage or intraperitoneal injection for 14 d. The next day after the last dose， blood was taken from the eyeball to separate serum and take colonic samples. Hematoxylin-eosin （HE） staining was used to observe the changes in tissue morphology. The content of D-lactate acid （D-LA） and diamine oxidase （DAO） in the serum was determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein expressions of VIP， cAMP， PKA， AQP3， and AQP4 were detected by Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultCompared with the blank group， the model group showed edema in the colonic submucosa， disordered arrangement of intestinal glands in the mucosal layer， loss of goblet cells， infiltration of inflammatory cells， and villus shedding. However， there were different degrees of improvement in each administration group. As compared with the blank group， the serum levels of DAO and D-LA in the model group were significantly increased （P<0.01）. As compared with the model group， the levels of DAO and D-LA in the high-dose oxaliplatin + Guiqi Baizhu prescription group and the level of D-LA in the medium-dose oxaliplatin + Guiqi Baizhu prescription group were decreased （P<0.05， P<0.01）. As compared with the oxaliplatin group， the levels of D-LA in the high and medium-dose oxaliplatin + Guiqi Baizhu prescription groups were decreased （P<0.05）， and the levels of DAO and D-LA in other administration groups were decreased as well， but the difference had no statistical significance. As compared with the blank group， the mRNA and protein expression levels of VIP， cAMP， PKA， AQP3， and AQP4 in the model group were significantly decreased （P<0.05， P<0.01）. As compared with the model group， the mRNA and protein expression levels of VIP， cAMP， PKA， AQP3， and AQP4 in each administration group were increased， and those in the high-dose oxaliplatin + Guiqi Baizhu prescription group were significantly increased （P<0.05， P<0.01）， while the protein expression level of cAMP in the medium-dose oxaliplatin + Guiqi Baizhu prescription group were increased （P<0.05）. As compared with the oxaliplatin group， the protein expression levels of cAMP in the high-dose oxaliplatin + Guiqi Baizhu prescription group were increased （P<0.05）， and the mRNA and protein expressions of these indexes in the other groups were also increased but the differences were not statistically significant.

ObjectiveTo observe the effect of Huangqi Baihe granules on the hypoxia-inducible factor 1α （HIF-1α）/nuclear factor-κB （NF-κB）/NOD-like receptor hot protein domain related protein 3 （NLRP3） signaling pathway in a rat model of high altitude hypoxia. MethodSixty male SPF SD rats were randomly divided into blank group， model group， dexamethasone group （5 mg·kg^-1）， and high， middle， and low-dose groups of Huangqi Baihe granules （4.1， 2.05， 1.025 g·kg^-1）. Among them， each Chinese medicine group was administrated orally for continuously 14 d， once a day， and the dexamethasone group was injected intraperitoneally for continuously 3 d as the positive control group. On the 15^th d， the model group， dexamethasone group， and high， middle， and low dose groups of Huangqi Baihe granules were exposed to the simulated high altitude， low pressure， and low oxygen environment in the animal low-pressure simulation cabin， and the exposure lasted for 3 d. Blood was collected from the abdominal aorta and serum was separated， and the brain tissue was taken after being killed. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in brain tissue. Enzyme-linked immunosorbent assay （ELISA） was used to detect the content of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β） in rat serum. Western blot was used to detect HIF-1α， NLRP3， phosphorylated nuclear factor-κB （p-NF-κB）， NF-κB， desquamation D （GSDMD）， and cysteine aspartate-specitis protein-1（Caspase-1） in rats of each group. The mRNA expression levels of HIF-1α， NLRP3， NF-κB p65， GSDMD， and Caspase-1 were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultThe results of HE staining showed that as compared with the normal group， the pathological sections of brain tissues in the model group showed that pyramidal cells were loosely arranged and distributed in disorder， with different sizes. Compared with the model group， the pathological changes in pyramidal cells in the dexamethasone group and high and middle-dose groups of Huangqi Baihe granules were reduced. The results of ELISA showed that as compared with the normal group， the content of TNF-α， IL-6， and IL-1β in the serum of rats in the model group was significantly higher （P<0.01）. Compared with the model group， the content of TNF-α， IL-6， and IL-1β in the serum of rats in the dexamethasone group and high and middle-dose groups of Huangqi Baihe granules decreased significantly （P<0.05， P<0.01）. The results of Western blot showed that as compared with the normal group， the relative protein expression levels of HIF-1α， NLRP3， p-NF-κB p65， GSDMD， and Caspase-1 in the brain tissue of the model group were significantly higher （P<0.01）. As compared with the model group， the relative expressions of HIF-1α， NLRP3， p-NF-κB p65， GSDMD， and Caspase-1 in the brain tissue of rats in the dexamethasone group and the high-dose group of Huangqi Baihe granules were significantly decreased （P<0.05， P<0.01）. The relative protein expression levels of HIF-1α， NLRP3， p-NF-κB p65， and Caspase-1 in the brain tissue of rats in the middle-dose group of Huangqi Baihe granules decreased significantly （P<0.01）， and the relative protein expression of HIF-1α in the brain tissue of rats in the low-dose group of Huangqi Baihe granules was reduced （P<0.05）. The Real-time PCR analysis showed that as compared with the normal group， the mRNA expression levels of HIF-1α， NLRP3， NF-κB p65， GSDMD， and Caspase-1 in the brain tissue of the model group were significantly increased （P<0.01）. As compared with the model group， the mRNA expression levels of HIF-1α， NLRP3， NF-κB p65， GSDMD， and Caspase-1 in the brain tissue of rats in the dexamethasone group were significantly decreased （P<0.01）. The mRNA expression levels of HIF-1α， NF-κB p65， GSDMD， and Caspase-1 in the brain tissue of rats in the high-dose group of Huangqi Baihe granules decreased significantly （P<0.01）. The mRNA expression levels of HIF-1α， NLRP3， and Caspase-1in the brain tissue of rats in the middle-dose group of Huangqi granules decreased （P<0.05， P<0.01）. ConclusionThe protective effect of Huangqi Baihe granules on acute brain injury in low-pressure hypoxic rats may be related to the HIF-1α/NF-κB/NLRP3 signaling pathway.

Oxidative stress plays a crucial role in cadmium (Cd)-induced myocardial injury. Mitsugumin 53 (MG53) and its mediated reperfusion injury salvage kinase (RISK) pathway have been demonstrated to be closely related to myocardial oxidative damage. Potentilla anserina L. polysaccharide (PAP) is a polysaccharide with antioxidant capacity, which exerts protective effect on Cd-induced damage. However, it remains unknown whether PAP can prevent and treat Cd-induced cardiomyocyte damages. The present study was desgined to explore the effect of PAP on Cd-induced damage in H9c2 cells based on MG53 and the mediated RISK pathway. For in vitro evaluation, cell viability and apoptosis rate were analyzed by CCK-8 assay and flow cytometry, respectively. Furthermore, oxidative stress was assessed by 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) staining and using superoxide dismutase (SOD), catalase (CAT), and glutathione/oxidized glutathione (GSH/GSSG) kits. The mitochondrial function was measured by JC-10 staining and ATP detection assay. Western blot was performed to detect the expression of proteins related to MG53, the RISK pathway, and apoptosis. The results indicated that Cd increased the levels of reactive oxygen species (ROS) in H9c2 cells. Cd decreased the activities of SOD and CAT and the ratio of GSH/GSSG, resulting in decreases in cell viability and increases in apoptosis. Interestingly, PAP reversed Cd-induced oxidative stress and cell apoptosis. Meanwhile, Cd reduced the expression of MG53 in H9c2 cells and inhibited the RISK pathway, which was mediated by decreasing the ratio of p-Akt^Ser473/Akt, p-GSK3β^Ser9/GSK3β and p-ERK1/2/ERK1/2. In addition, Cd impaired mitochondrial function, which involved a reduction in ATP content and mitochondrial membrane potential (MMP), and an increase in the ratio of Bax/Bcl-2, cytoplasmic cytochrome c/mitochondrial cytochrome c, and Cleaved-Caspase 3/Pro-Caspase 3. Importantly, PAP alleviated Cd-induced MG53 reduction, activated the RISK pathway, and reduced mitochondrial damage. Interestingly, knockdown of MG53 or inhibition of the RISK pathway attenuated the protective effect of PAP in Cd-induced H9c2 cells. In sum, PAP reduces Cd-induced damage in H9c2 cells, which is mediated by increasing MG53 expression and activating the RISK pathway.

Hypoxia is one of the factors restricting the survival of people at high altitudes, which can cause various symptoms such as vomiting, diarrhea, palpitations, shortness of breath and acute coma. About 80% of patients with acute mountain sickness have at least one symptom of a gastrointestinal distress (e. g., anorexia, nausea, diarrhea, vomiting, etc.). The pathological characteristics, pathogenesis and drug treatment of intestinal injury caused by high-altitude hypoxia were studied, which is conducive to the diagnosis and treatment of plateau gastrointestinal diseases. Therefore, by summarized relevant literature and systematically expounds the related researches on intestinal damage caused by high altitude hypoxia. We summarized the changes of intestinal morphology, intestinal cells, intestinal flora and other intestinal homeostasis caused by high altitude hypoxia, the mechanism of intestinal inflammation and oxidative damage, and the treatment of traditional Chinese medicine, which provide reference and information for reference for scientific research workers and clinicians.

Objective: To investigate the origin of infection and risk factors of a case with SARS-CoV-2 infection associated with overseas countries in the Ningbo-Zhoushan Port, Zhejiang Province, so as to provide the evidence for improving the COVID-19 control measures at ports. Methods: Ningbo Center for Disease Control and Prevention ( CDC ) and Beilun CDC conducted case finding and epidemiological surveys immediately after being informed. The general information, history of vaccination and the travel during the latest 14 days were collected from the positive case, and all close contacts were tracked. Saliva samples were collected for SARS-CoV-2 nucleic acid testing and whole-genome sequencing, and the sequencing results were aligned with the GISAID's EpiCoV database. The origin of infection and transmission route of the positive case was investigated. Results: A case was identified positive for SARS-CoV-2 nucleic acid during company M's routine screening in the Ningbo-Zhoushan Port on August 10, 2021, and was confirmed positive for SARS-CoV-2 nucleic acid by Beilun CDC and Ningbo CDC on August 11. Whole-genome sequencing showed SARS-CoV-2 B.1.617.2 ( Delta ) variant, which shared the highest homology with the virus sequence uploaded by Russia on June, 2021 ( Russia/MOW-RII-MH27356S/2021 ). The case was a bundling worker for overseas container ships, and reported communicated with foreign boatmen and contacted materials without protected interventions on the SINOKOR AKITA Container Ship between August 4 and 5, 2021. This ship anchored at Vladivostok, Russia from July 27 to 29, anchored at Ningbo Harbor on August 4, and departed on August 5. Then, 11 boatmen from this ship were tested positive for SARS-CoV-2 nucleic acid on August 8. One asymptomatic case was reported in this epidemic; 254 close contacts and 617 secondary close contacts were identified, and all were tested negative for SARS-CoV-2 nucleic acid. No new cases with SARS-CoV-2 infections were detected until August 25, 2021, and the emergency response was therefore terminated. Conclusions The infection was a sporadic COVID-19 epidemic associated with overseas countries, which was caused by Delta variant infection through contacts with foreign boatmen or materials by a bundling worker in Ningbo-Zhoushan Port; fortunately, no epidemic spread occurred. Intensified closed-loop management and increased frequency of SARS-CoV-2 nucleic acid test among high-risk populations, and improving the precision and rapid emergency treatment of COVID-19 epidemics are required for the containment of COVID-19 at ports.

Objective:To investigate the changes of serum catecholamines (CST) and oxidative stress index in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) with hypertension and the correlation with blood pressure.Methods:Total of 100 OSAHS patients admitted to Jingmen No.1 People′s Hospital from February 2018 to August 2020 were selected. According to whether patients combined with hypertension, they were divided into OSAHS group (54 cases) and OSAHS combined with hypertension group (46 cases). The changes of serum CST and oxidative stress index in the two groups were compared and analyzed the correlation of blood pressure and CST and oxidative stress index.Results:The level of myeloperoxidase(MPO) in the OSAHS combined with hypertension group was higher than that in the OSAHS group: (41.67 ± 3.02) U/L vs. (39.11 ± 2.65) U/L; the levels of catalase (CAT) and CST in the OSAHS combined with hypertension group were higher than those in the OSAHS group: (11.47 ± 2.54) kU/L vs. (15.88 ± 2.31) kU/L, (23.63 ± 4.38) ng/L vs. (28.61 ± 5.42) ng/L, there were statistically differences ( P<0.05). The levels of respiratory disturbance index, lowest oxygen saturation, triacylglycerol, total cholesterol, low density lipoprotein cholesterin, high density lipoproteincholesterol, epinephrine, noradrenaline in the two groups had no significant differences ( P>0.05). Spearman correlation analysis showed that the systolic pressure and diastolic pressure had positive correlation with MPO ( P<0.05), and had negative correlation with CAT and CST ( P<0.05). Conclusions:The serum CST and CAT are down-regulated in patients with OSAHS with hypertension, and serum MPO is up-regulated. Oxidative stress may be related to OSAHS with hypertension.
