This article reports a diagnostically and therapeutically challenging case of small intestinal marginal zone lymphoma. The patient presented with recurrent abdominal pain as the chief complaint, and imaging revealed multifocal small bowel wall thickening with high uptake, multisegmental luminal stenosis, and proximal dilation. Initial diagnostic workup, including gastroscopy, colonoscopy, and enteroscopy with biopsy, failed to establish a definitive diagnosis. Empirical anti-tuberculosis therapy was ineffective. A repeat enteroscopic biopsy performed over eight months after symptom onset eventually confirmed the diagnosis of mucosa-associated lymphoid tissue (MALT) extranodal marginal zone lymphoma. Despite three different chemotherapy regimens, the patient's intestinal obstruction symptoms persisted, with imaging still showing multifocal bowel wall thickening and hypermetabolic activity. A critical diagnostic dilemma arose regarding whether the PET/CT-positive lesions represented residual lymphoma or fibrotic scarring, whether further chemotherapy adjustments were warranted, and whether surgical resection was necessary. Multidisciplinary discussion concluded that imaging had limited discriminatory value in this scenario and that surgical intervention should be pursued if feasible. The patient successfully underwent partial small bowel resection, with postoperative pathology confirming no residual lymphoma but significant fibrotic changes. The patient has since resumed a normal diet, with body weight nearly restored to pre-illness levels. This case highlights that fibrotic transformation is a common sequela of treated marginal zone lymphoma and that PET/CT may misleadingly suggest residual disease, potentially leading to unnecessary chemotherapy. Timely surgical intervention is crucial in such scenarios.

The chloroplast genome encodes many key proteins involved in photosynthesis and other metabolic processes, and metabolites synthesized in chloroplasts are essential for normal plant growth and development. Root-UVB (ultraviolet radiation B)-sensitive (RUS) family proteins composed of highly conserved DUF647 domain belong to chloroplast proteins. They play an important role in the regulation of various life activities such as plant morphogenesis, material transport and energy metabolism. This article summarizes the recent advances of the RUS family proteins in the growth and development of plants such as embryonic development, photomorphological construction, VB6 homeostasis, auxin transport and anther development, with the aim to facilitate further study of its molecular regulation mechanism in plant growth and development.

Objective:To evaluate the application value of serum carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9 and CA72-4 detection in the opportunistic screening (healthy physical examination) of gastric cancer based on a meta-analysis.Methods:A published literature searching up to May 2023 was performed in databases of CNKI, Wanfang Databases, VIP, PubMed, Cochran and Embase for studies on CEA, CA19-9 and CA72-4 detection and diagnosis of gastric cancer. The Quality Evaluation Tool of Diagnostic Accuracy Studies (QUADAS-2) was used to evaluate the quality of the literature. Stata17.0 statistical software was used for meta-analysis.Results:According to the inclusion and exclusion criteria, a total of 23 studies with 5 287 gastric cancer patients and 6 129 controls were included. The pooled sensitivity and specificity of serum CEA, CA19-9 and CA72-4 as a diagnostic marker for gastric cancer were 0.42, 0.45 and 0.52, and 0.94, 0.91 and 0.95, respectively. The area under the summary receiver operating characteristic (sROC) curve for discriminating gastric cancer was 0.82, 0.77 and 0.87, respectively. The sensitivity of combined (parallel) diagnosis of gastric cancer with the three biomarkers increased to 0.66 (95% CI: 0.54-0.76), the specificity decreased to 0.85 (95% CI: 0.81-0.89), and the area under the curve basically remained unchanged at 0.86 (95% CI: 0.83-0.89). Conclusions:Due to poor sensitivity, the application effects of serum CEA, CA19-9 and CA72-4 as biomarkers for gastric cancer screening and physical examination are limited.

Objective:To explore the correlation between periodontitis (PD) and chronic kidney disease (CKD) in adults, as well as the potential mechanisms involved.Methods:Data on PD and CKD from the National Health and Nutrition Examination Survey (NHANES) database between 1999 and 2014 were downloaded. Weighted univariate and multivariate logistic regression analyses were conducted to investigate the risk factors associated with PD and CKD, considering demographic and clinical indicators. Using publicly available genome-wide association study (GWAS) summary datasets for CKD and PD as outcome variables, as well as 731 immune cell phenotypes and 91 inflammatory proteins as exposure factors from the OPEN GWAS database, a two-sample Mendelian randomization (TSMR) analysis was performed using the inverse-variance weighted (IVW) method.Results:Seven demographic indicators including gender, age, race, education level, marital status, income, and health are related to the incidence of CKD and PD. Among them, the elderly (≥60 years old), poverty (poverty-income ratio <1.3), divorce or widowhood, and male ratio in the comorbidity group of CKD and PD [67.12% (833/1 241), 36.83% (457/1 241), 34.41% (427/1 241), and 57.78% (717/1 241) respectively] were significantly higher than those in the control group [23.71% (4 179/17 623), 29.17% (5 141/17 623), 18.16% (3 200/17 623), and 48.73% (8 587/17 623) respectively] (all P<0.001). Those with high educational level (university and above) and self-rated excellent health accounted for a relatively small proportion in the comorbidity group [14.10% (175/1 241) and 8.22% (102/1 241) respectively]. The prevalence of PD increased among individuals with abnormal renal function indices, including glomerular filtration rate, urine protein/creatinine ratio, serum creatinine, serum uric acid, and blood urea nitrogen. Univariate logistic regression analysis showed a positive correlation between the incidence of PD and CKD ( OR=2.14, 95 %CI: 1.90-2.42, P<0.001). Multivariate logistic regression analysis also indicated that PD and CKD were potential risk factors for each other (PD for CKD: OR=1.22, 95 %CI: 1.07-1.40, P=0.004; CKD for PD: OR=1.19, 95 %CI: 1.04-1.37, P=0.012). Furthermore, after adjusting the model based on demographic indicators, there was still a significant correlation between PD and CKD ( P=0.010). Mechanistically, the results of the TSMR analysis support the existence of a common risk factor mediated by immune cells between CKD and PD, namely the expression of CD64 on multiple innate immune cells mediates the occurrence of CKD and PD. The absolute count of CD64 + monocytes is associated with an increased risk for both CKD ( HR=1.11) and PD ( HR=1.07), while same tendency showed in the absolute count of CD64 + neutrophils for CKD ( HR=1.22) and PD ( HR=1.23). Conclusions:There is a positive correlation between CKD and PD, particularly moderate to severe PD, and the shared pathogenesis involves CD64 + monocytes in the circulatory system. Targeted interventions focusing on CD64 molecules or monocyte subsets may be beneficial.

Objective:To investigate the predictive value of inflammatory and nutritional indices for postoperative survival of elderly patients with esophageal squamous carcinoma.Methods:The retrospective cohort study was conducted. The clinicopathological data of 130 elderly patients with esophageal squamous carcinoma who were admitted to Sichuan Cancer Hospital from January 2019 to April 2020 were collected. There were 102 males and 28 females, aged (70±4)years. Mea-surement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test. Receiver opera-ting characteristic (ROC) curves were plotted. The area under the curve (AUC) and optimal cut-off values were calculated. The Kaplan-Meier method was used to plot survival curves, and the Log-rank test was used for survival analysis. The COX proportional hazard regression model was used for univariate and multivariate analyses. Results:(1) Postoperative survival of elderly patients with esophageal squamous carcinoma predicted by inflammatory and multitional indices. Results of ROC curves analysis showed that the best cut-off values of preoperative systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and prognostic nutrition index (PNI) for predicting postoperative survival of elderly patients with esophageal squamous carcinoma were 470.71×10 9/L, 1.11, 2.07, 136.24, and 46.28, respectively. (2) Risk factors analysis of postoperative survival of elderly patients with esophageal squamous carcinoma. Results of multivariate analysis showed that preoperative SII ≥470.71×10 9/L, preoperative SIRI ≥1.11, preoperative PNI<46.28, score of preoperative patient-generated subjective global assessment (PG-SGA) ≥4, postoperative pathological stage Ⅳ and post-operative complications were independent risk factors for the overall survival time of elderly patients with esophageal squamous carcinoma ( hazard ratio=3.30, 2.50, 0.36, 4.86, 1.57, 1.97, 95% confidence interval as 1.10?9.88, 1.07?5.88, 0.16?0.81, 1.13?20.87, 1.20?2.06, 1.02?3.82, P<0.05). (3) Follow-up. All the 130 patients were followed up for 39(range, 1?60)months. Of the 130 patients, 81 cases survived, 49 cases died, and the median overall survival time was not reached. The 1- and 3-year survival rates of the 130 patients were 83.85% and 54.62%, respectively. ① The median overall survival time was 25(0,43)months for patients with SII ≥470.71×10 9/L, and unreached for patients with SII <470.71×10 9/L, showing a significant difference between them ( χ2=60.59, P<0.05). ② The median overall survival time was 26(0,44)months for patients with SIRI ≥1.11, and unreached for patients with SIRI <1.11, showing a significant difference between them ( χ2=45.57, P<0.05). ③ The median overall survival time was unreached for patients with PNI ≥46.28, and 38(0,47)months for patients with PNI <46.28, showing a significant difference between them ( χ2=12.53, P<0.05). ④ The median overall survival time was unreached for patients with PG-SGA <4 and ≥4, showing a signifi-cant difference between them ( χ2=14.41, P<0.05). ⑤ The median overall survival time was 25(1,47)months for patients in pathological stage Ⅲ, 12(1,32)months for patients in stage Ⅳ, and unreached for patients in stage 0, Ⅰ, Ⅱ, respectively, showing a significant difference among them ( χ2=58.75, P<0.05). ⑥ The median overall survival time was 33(1,47)months for patients with postoperative complication, and unreached for patients without postoperative complication, showing a significant difference between them ( χ2=14.27, P<0.05). Conclusions:Preoperative SII, SIRI and PNI have good predictive value for postoperative survival in elderly patients with esophageal squamous carcinoma. Preoperative SII ≥470.71×10 9/L, preoperative SIRI ≥1.11, preoperative PNI <46.28, score of preoperative PG-SGA ≥4, postoperative pathological stage Ⅳ, and postoperative complications are independent risk factors for the overall survival time of elderly patients with esophageal squamous carcinoma. Patients with preoperative SII <470.71×10 9/L, preoperative SIRI <1.11, preoperative PNI >46.28, score of preoperative PG-SGA <4, postoperative pathological stage 0, Ⅰ, Ⅱ, and non post-operative complications have better survival.

Objective:To analyze the learning styles of intensive care specialist nurses and to explore the application effects of the teaching method based on Kolb's learning style theory in intensive care specialist nurse training.Methods:Nurses who participated in the intensive care specialist nurse training in Chongqing during 2022 and 2023 were selected as the research subjects. Among them, the 49 nurses from 2022 were assigned to the control group, while the 50 nurses from 2023 were assigned to the experimental group. Before the training, the Kolb's Learning Style Scale was used to investigate the two groups of nurses. A new training method based on different learning styles was used in the experimental group, while the conventional training method was used in the control group. The theory, clinical practice, and satisfaction scores were compared between the two groups after training. SPSS 21.0 was used for the t-test, chi-square test, or Fisher's exact test. Results:The learning styles of the two groups were similar, with the highest proportion observed in divergent type, followed by assimilation type, and the lowest proportions in convergent type and compliant type, albeit without significant differences. The experimental group showed higher scores of theory, clinical practice, and satisfaction compared to the control group [(77.20±8.34) vs. (80.38±5.50), t=-2.24, P=0.027; (93.73±1.83) vs. (95.31±1.07), t=-5.20, P<0.001; (20.57±2.09) vs. (22.62±1.61), t=-5.46, P<0.001] Conclusion:The teaching method based on Kolb's learning style theory can improve the theory and clinical practice scores and the overall satisfaction of nurses who participate in the intensive care specialist nurse training.

Objective:To investigate the role of dietary fiber in the intestinal rehabilitation for patients with ultra-short bowel syndrome.Methods:This study included 34 inpatients diagnosed with ultra-short bowel syndrome in the General Surgery Department of the Eastern Theater General Hospital of the People's Liberation Army from January 2012 to October 2023. Patients were grouped based on whether they received intestinal rehabilitation and whether dietary fiber was added to the treatment plan, and were divided into three groups: nutritional therapy group (11 cases), growth hormone + glutamine intestinal rehabilitation treatment group (10 cases) and growth hormone injection + glutamine + dietary fiber intestinal rehabilitation treatment group (13 cases). The therapeutic regimen and its changes, pre- and post-treatment parameters of hematology, nutrition, intestinal absorption, fecal consistency, and quality of life were recorded and compared, and the impact of different treatment regimens on clinical outcomes was analyzed.Results:Compared with nutrition treatment group and growth hormone + glutamine intestinal rehabilitation treatment group, growth hormone injection + glutamine + dietary fiber intestinal rehabilitation treatment group, the increase of enteral nutritional fluid, the decrease of parenteral nutritional energy, the increase of intestinal moisture absorption, the decrease of defecation times and the appreciation of hemoglobin were significantly increased, and the difference was statistically significant ( P<0.05). At the same time, the levels of insulin-like growth factor 1 and insulin-like growth factor binding protein were significantly increased after treatment ( P<0.01). Conclusions:Nutritional support combined with intestinal rehabilitation can significantly improve the nutritional status and intestinal absorption rate of ultra-short bowel syndrome patients. The use of dietary fiber in the intestinal rehabilitation regimen for ultra-short bowel syndrome patients yields more significant benefits, as evidenced by improved clinical outcomes.
