Objective To analyze the clinical manifestations, computed tomography scan (CT), gastroscope, endo-scopic ultrasonography (EUS), and therapy method of gastritis cystica profunda. Methods Retrospectively analyzed clinical manifestations, CT, gastroscope, EUS, and pathological results of 6 cases of gastritis cystica profunda. Results In these 6 cases, 3 of them were doubted gastric carcinoma, 3 cases were considered stomach mass by CT. Gastroscope hinted apophysis lesions, but all cases were suggested gastritis cystica profunda by EUS. And all cases were removed through endoscopic submucosal dissection (ESD). Pathology were confirmed the diagnosis. Conclusion EUS combined with endoscopic mucosal resection (EMR) or ESD technique can improve the diagnostic rate. For gas-tritis cystica profunda which are not associated with malignant tumor can be treated through ESD.

Obiective To investigate the molecular characteristics of heteroresistant vancomycinintermediate Staphylococcus aureus(hVISA)in China and analyze the differences of the molecular characteristics between hVISA and VSSA(vancomycin-susceptible Staphylococcus aureus)isolates.Methods A total of 3 15 non-repetitive MBSA were collected from the national surveillance program in China in 2007.The isolates of hVISA were confirmed by modified population analysis profile-area under the curve(PAP-AUC).The genotypes of agr and SCCmec were determined by multiplex PCR,and spa typing was performed bv PCR and DNA sequencing.The pvl gene was detected bv PCR Results The prevalence of hVISA was 9.5%(30/315).Among 315 MRSA,SCCmec Ⅲ was the most popular type,which was found in 234 isolates(234/315,74.3%),followed by SCCmec Ⅱ,which was identified in 56 isolates (56/315,17.8%).The rate of SCCmec Ⅱ in hVISA(46.7%)was significantly hisher than in VSSA (14.7%,X~2=18.93,P＜0.001).The most prevalent agr type among 315 MRSA was agr 1 accounting for 73.6%(232/315).The agr 2 accounted for 18.7%(59/315),and agr 3 and agr 4 were very rare in clinical isolates.It was different in agr types between the two groups.The rate of agr 2 in hVISA(53.4%)was higher than in VSSA(15.1%).X~2 value was 26.08 and P value was less than 0.001 through X~2 test.There was a statistical significance in the result.There were 4 spa types in hVISA isolates,including t002 (13 isolates),t037(9 isolates),t030(6 isolates),and 1548(2 isolates).The pvl positive MRSA isolates were very low,accounting for 1.6%(5/315).Conclusions The prevalence of hVISA was relatively higher in China.Compared to VSSA,the majority(53.4%)of the hVISA strains were agr 2,which was obviously different from VSSA.hVISA isolates were more diverse by spa typing,

Objective To investigate whether macrophage-activating lipopeptide-2 ( MALP-2) in-duces the expression of hemoxygenase-1 ( HO-1 ) in THP-1 cells and to further elucidate its possible regulatory mechanism for a better understanding of protective response upon mycoplasma infection .Methods THP-1 cells were cultured in vitro and stimulated by MALP-2 at different concentrations for 12 h.THP-1 cells were incubated with TLR 2 or TLR6 neutralizing antibodies , or transfected with their dominant negative plasmids to evaluate the effects of TLR 2 and TLR6 on HO-1 expression .Phosphorylation of Akt was detected by Western blot.PI3K inhibitor LY294002 was used to investigate the role of PI3K in HO-1 expression.Im-munofluorescence and electrophoretic mobility shift assay ( EMSA ) were performed to observe the nuclear translocation and DNA-binding activity of nuclear factor Nrf 2.Small interfering RNA ( siRNA) was used to silence the genes encoding Nrf2 and HO-1.Cobalt protoporphyrin (CoPP), an inducer of HO-1, was used to treat THP-1 cells.The expression of HO-1 was detected by Western blot .The secretion of TNF-αand IL-1βby THP-1 cells were measured by ELISA .Results MALP-2 induced the expression of HO-1 in THP-1 cells.However, the expression of HO-1 was inhibited by TLR2 and TLR6 neutralizing antibodies and expres-sion of their dominant negative plasmids .Moreover, PI3K pathway was activated by MALP-2, and with the use of PI3K inhibitor, the expression of HO-1 was decreased.The translocation of Nrf2 to the nucleus and itsDNA-binding activity were enhanced by MALP-2, but were inhibited by the treatment of PI3K inhibitor.Theexpression of HO-1 was significantly down-regulated upon the interference of Nrf2 gene expression withsiRNA.Silenced expression of HO-1 increased the level of TNF-αand IL-1β, while CoPP treatment decreasedthe secretion of MALP-2-induced cytokines.Conclusion MALP-2 might induce the expression ofHO-1 in THP-1 cells through TLR2,6/PI3K/Nrf2 pathways.The expression of HO-1 could negatively regulatethe hyper-secretion of cytokines.

Objective:In order to understand the changing trends of gastric cancer incidence and mortality in early-onset and late-onset in China from 2000 to 2019.Methods:The Global Burden of Disease research data was collected, and Excel and R 4.2.1 softwares were used to examine the incidence rate, mortality rate, and disability-adjusted life years (DALY) of Chinese people from 2000 to 2019, with a focus on gender, age, and year.Results:In 2019, the crude incidence rates were 7.06/100 000 (95% UI: 6.63/100 000-7.59/100 000) and 114.52/100 000 (95% UI: 108.79/100 000-121.63/100 000) for early- and late-onset gastric cancer, respectively. The crude mortality rate for early-onset gastric cancer was 3.29/100 000 (95% UI: 3.11/100 000- 3.50/100 000), while the crude mortality rate for late-onset gastric cancer was 81.88/100 000 (95% UI: 78.15/100 000-86.04/100 000). Additionally, the crude DALY rates for these two types of gastric cancer were 156.48/100 000 (95% UI: 148.82/100 000-165.84/100 000) and 1 750.13/100 000 (95% UI: 1 661.21/100 000-1 852.99/100 000). The standardized incidence of early-onset gastric cancer decreased from 5.49/100 000 in 2000 to 4.76/100 000 in 2019, and that of late-onset gastric cancer decreased from 143.45/100 000 in 2000 to 123.02/100 000 in 2019.The standardized mortality rate of early-onset gastric cancer decreased from 4.16/100 000 in 2000 to 2.18/100 000 in 2019, and that of late-onset gastric cancer decreased from 140.82/100 000 in 2000 to 91.49/100 000 in 2019. The standardized DALY rate for early-onset gastric cancer in 2019 was 105.87/100 000 (95% UI: 87.98/100 000 -125.60/100 000), lower than 198.84/100 000 (95% UI: 179.47/100 000- 219.83/100 000) in 2000. The standardized DALY rate for late onset gastric cancer in 2019 was 1 821.11/100 000 (95% UI: 1 509.42/100 000-2 158.53/100 000), lower than 2 932.52/100 000 (95% UI: 2 665.92/100 000-3 252.60/100 000) in 2000. Conclusions:The standardized mortality rate of early-onset gastric cancer in China showed a decreasing trend from 2000 to 2019. The standardized mortality rate of late onset gastric cancer showed a trend of first increasing and then decreasing. Notably, the incidence, mortality, and DALY of late-onset gastric cancer were significantly higher than those of early-onset gastric cancer during this period. Additionally, male incidence, mortality, and crude DALY rates were higher than female.

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis-associated acute kidney injury (SA-AKI) is a common organ dysfunction of sepsis, and its incidence and mortality are increasing, which brings heavy economic burden to patients and society. Early diagnosis and effective intervention can block the occurrence and progression of SA-AKI effectively, improve prognosis, and reduce medical costs. Diagnosis on SA-AKI relies on urine volume and serum creatinine, which has the disadvantages of being easily disturbed and delaying. The identification of biomarkers in blood and urine can facilitate diagnosis and provide targeted therapy to enhance the management of SA-AKI. This article reviews the characteristics of a variety of SA-AKI biomarkers that have been found and validated, including pre-damage biomarkers, damage biomarkers and functional biomarkers, and explore the clinical value of newly discovered biomarkers related to the diagnosis and treatment of SA-AKI, such as blood uncoupling protein 2 (UCP2), Sestrin 2 protein and pannexin 1 (PANX1), to provide reference for the early diagnosis and effective treatment of SA-AKI.

Objective To explore the impact of the connect,introduce,communicate,ask,respond,exit(CICARE)communication model combined with feedback health education model on the compliance and anxiety level of elderly outpatients before colonoscopy.Methods A total of 346 patients aged ≥60 who visited the Outpatient Department,the Second Hospital of Jiaxing City for the first time and underwent colonoscopy from September to December 2023 were randomly divided into control group(n=86),communication group(n=84),feedback group(n=86),and combined group(n=90)using random number table method.The control group were provided routine education to patients undergoing colonoscopy through watching colon preparation videos,verbal education,and written propaganda educational materials;The communication group were implemented health education for colonoscopy by using the CICARE communication model;The feedback group were implemented health education for colonoscopy by using feedback method;The combined group were implemented the above education to patients by using the CICARE communication model combined with feedback method.The compliance with colon preparation,intestinal cleanliness,and patient anxiety scores before colonoscopy were evaluated and compared among the four groups.Results There were no statistically significant differences in dietary compliance and medication compliance among the four groups(P＞0.05),but there was a statistically significant difference in exercise compliance(P＜0.05).Different educational methods had statistical significance on patients'intestinal cleanliness and anxiety scores(P＜0.001),and further post hoc comparisons showed that the education method of the combined group could improve the overall intestinal cleanliness score and reduce patient anxiety score.Conclusion The health education model of the CICARE communication method combined with feedback has a significant effect on health education for elderly patients,which can improve the compliance with colon preparation and reduce patient anxiety scores.

Objective:To construct and validate a nomogram model for predicting sepsis-associated acute kidney injury (SA-AKI) risk in intensive care unit (ICU) patients.Methods:A retrospective cohort study was conducted. Adult sepsis patients admitted to the department of ICU of the 940th Hospital of Joint Logistic Support Force of PLA from January 2017 to December 2022 were enrolled. Demographic characteristics, clinical data within 24 hours after admission to ICU diagnosis, and clinical outcomes were collected. Patients were divided into training set and validation set according to a 7∶3 ratio. According to the consensus report of the 28th Acute Disease Quality Initiative Working Group (ADQI 28), the data were analyzed with serum creatinine as the parameter and AKI occurrence 7 days after sepsis diagnosis as the outcome. Lasso regression analysis and univariate and multivariate Logistic regression analysis were performed to construct the nomogram prediction model for SA-AKI. The discrimination and accuracy of the model were evaluated by the Hosmer-Lemeshow test, receiver operator characteristic curve (ROC curve), decision curve analysis (DCA), and clinical impact curve (CIC).Results:A total of 247 sepsis patients were enrolled, 184 patients developed SA-AKI (74.49%). The number of AKI patients in the training and validation sets were 130 (75.58%) and 54 (72.00%), respectively. After Lasso regression analysis and univariate and multivariate Logistic regression analysis, four independent predictive factors related to the occurrence of SA-AKI were selected, namely procalcitonin (PCT), prothrombin activity (PTA), platelet distribution width (PDW), and uric acid (UA) were significantly associated with the onset of SA-AKI, the odds ratio ( OR) and 95% confidence interval (95% CI) was 1.03 (1.01-1.05), 0.97 (0.55-0.99), 2.68 (1.21-5.96), 1.01 (1.00-1.01), all P < 0.05, respectively. A nomogram model was constructed using the above four variables. ROC curve analysis showed that the area under the curve (AUC) was 0.869 (95% CI was 0.870-0.930) in the training set and 0.710 (95% CI was 0.588-0.832) in the validation set. The P-values of the Hosmer-Lemeshow test were 0.384 and 0.294, respectively. In the training set, with an optimal cut-off value of 0.760, a sensitivity of 77.5% and specificity of 88.1% were achieved. Both DCA and CIC plots demonstrated the model's good clinical utility. Conclusion:A nomogram model based on clinical indicators of sepsis patients admitted to the ICU within 24 hours could be used to predict the risk of SA-AKI, which would be beneficial for early identification and treatment on SA-AKI.

Objective To study the correlation between serum prealbumin level before liver resection and prognosis of patients with primary hepatocellular carcinoma (HCC).Methods The clinical data of patients with HCC who underwent liver resection at the Affiliated Tumor Hospital of Guangxi Medical University from August 2007 to October 2016 were retrospectively analyzed.The previous albumin of 200 mg/L and the pre-albumin as predicted by the maximum selection rank statistic method were used as the bounding group,and reduced groups and the correlation between pre-operative serum pre-albumin levels and clinicopathological characteristics were analyzed.The Kaplan-Meier method was used to calculate the overall survival rate of patients with the different cutoff levels.The Cox proportional regression model was used to analyze,and cirrhosis,alpha-fetoprotein levels and Barcelona Clinic Liver Cancer staging were used to adjust the relationship between serum prealbumin and prognosis of liver resection for HCC patients.Analysis of stratified variables was performed and their interactions with serum prealbumin were analyzed.Results Of the 2 022 patients included in this study,there were 1 739 males and 283 females.Their age was 49.5 ± 11.2 years.The median follow-up was 37.4 months.The optimal cutoff value of prealbumin predicted by the maximum selection rank statistic method was 166 mg/L.Regardless of the cutoff values of previous albumin 200 mg/L or prealbumin 166 mg/L,multivariate analysis showed that preoperative serum prealbumin level was an independent prognostic risk factor for patients (P ＜0.05).The prognosis of patients with ＞200 mg/L (＞ 166 mg/L) serum prealbumin before surgery was significantly better than that of patients with ≤200 mg/L (≤166 mg/L) prealbumin,the differences were significant (all P ＜ 0.05).After adjusting for confounding factors,the prealbumin level correlated with prognosis of patients with HCC [cutoff value 200 mg/L:HR (95％ CI) was 1.59 (1.35-1.86),cutoff value 166 mg/L:HR (95％ CI) was 1.69 (1.44-1.98),all P ＜ 0.05].The results of stratified analysis showed that the relationship between prealbumin levels and the prognosis of HCC patients became more robust.Conclusions Preoperative serum prealbumin was an independent risk factor for prognosis of HCC patients,and it had predictive value on prognosis of HCC patients.
