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.

【Objective】 To investigate the differences in efficacy and long-term prognosis between locally progressive low and intermediate rectal cancer patients receiving fluorouracil-based neoadjuvant chemotherapy alone (mFOLFOX6/CapeOX) and neoadjuvant radiotherapy, and to compare the therapeutic efficacy in the two groups. 【Methods】 We retrospectively analyzed the clinicopathological data of 118 patients with locally progressive low and intermediate rectal cancer who received neoadjuvant therapy from January 2019 to December 2021 at The First Affiliated Hospital of Xi’an Jiaotong University, including gender, age, body mass index (BMI), and other clinicopathological parameters. The t-test, Mann Whitney test, chi-square test or Fisher’s exact test were used to compare the differences between the two groups of patients who received neoadjuvant chemotherapy alone or neoadjuvant radiochemotherapy in terms of short-term efficacy, lymph node manifestations and long-term prognosis, respectively. Survival rates were calculated and survival curves were plotted using the Kaplan-Meier method. 【Results】 In terms of efficacy, patients in the neoadjuvant radiotherapy group achieved better tumor regression (Z=-2.05, P=0.04) and solid tumor efficacy (Z=-2.42, P=0.015), but the difference between the two groups in terms of downstaging effect of clinical stage was not statistically significant. The number of lymph nodes detected was significantly lower in the neoadjuvant radiotherapy group (neoadjuvant chemotherapy vs. neoadjuvant radiochemotherapy, 13.19±3.83 vs. 9.55±4.00, t=5.02, P<0.001), but the two groups did not differ significantly in the number of lymph node positives and lymph node positive ratio. In terms of long-term prognosis, there was no statistically significant difference in the overall survival rate or disease-free survival rate of the two groups. 【Conclusion】 Compared with neoadjuvant chemotherapy alone, neoadjuvant radiotherapy showed better short-term efficacy in patients with locally progressive low and intermediate rectal cancer, but there was no statistically significant difference between the two treatment regimens in terms of long-term prognosis.

Hypertension and its associated cardiovascular diseases such as stroke and ischemic heart disease result in a high burden of disease and health losses, making it the most burdensome disease in the world and one of the important public health issues in China. Currently Chinese scholars have carried out a large number of studies on the prevalence of hypertension, including regional and national prevalence studies. However, long-term follow-up studies on incidence of hypertension are relatively few and mostly limited to specific ages and regions. This paper summarizes the prevalence, incidence and epidemiological trend of hypertension in Chinese adults. The hypertension prevalence increased from 5.1% in 1959 to 27.5% in 2018, and presents an overall trend of high in the north and low in the south. The hypertension incidence is at a high level (the cumulative incidence was 33.4% after 22 years-follow-up), but there are few researches on the trend of hypertension incidence in huge region.

Patient-based real-time QC (PBRTQC) uses patient-derived data to assess assay performance. PBRTQC algorithms have advanced in parallel with developments in computer science and the increased availability of more powerful computers. The uptake of Artificial Intelligence in PBRTQC has been rapid, with many stated advantages over conventional approaches. However, until this review, there has been no critical comparison of these. The PBRTQC algorithms based on moving averages, regression-adjusted real-time QC, neural networks and anomaly detection are described and contrasted. As Artificial Intelligence tools become more available to laboratories, user-friendly and computationally efficient, the major disadvantages, such as complexity and the need for high computing resources, are reduced and become attractive to implement in PBRTQC applications.

Osteoarthritis (OA) is a chronic degenerative joint disease whose main characteristic is the destruction of articular cartilage, causing pain and disability in patients and seriously affecting their quality of life. OA can be induced by a variety of causes, and pathological changes in articular cartilage are considered to be one of the key driving factors for the occurrence of OA. High mobility group box-1 protein (HMGB1), as a non-histone protein in eukaryotic cells, can participate in regulating the inflammation and apoptosis process of OA chondrocytes, thus leading to the occurrence of OA. This article reviews the research on the mechanism of HMGB1 in OA chondrocytes, with a view to providing new ideas for the clinical prevention and treatment of OA.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Lipedema is a disease in which local fat deposits in the body are the main clinical manifestations. It is often characterized by a disproportionate increase in subcutaneous fat tissue in the extremities, buttocks or hip joints. It is often misdiagnosed as obesity or lymphedema in clinical practice. The pathogenesis is not clearly understood, and there is no standardized clinical treatment method. This paper elaborated on the research status of the pathogenesis of lipedema, and summarized the clinical manifestations and classification, diagnosis and differential diagnosis, treatment methods, etc., aiming to provide up-to-date perspectives of lipedema.
