Objective:To investigate the diagnostic value of magnetically controlled capsule gastroscope in elderly patients with suspected upper gastrointestinal bleeding.Methods:A total of 102 patients with suspected upper gastrointestinal bleeding who underwent magnetically controlled capsule gastroscopy (MCCG) in General Hospital of Ningxia Medical University from October 2020 to September 2022 were enrolled. Patients were divided into two groups according to age: 38 patients in group A (≤65 years old) and 64 patients in group B (> 65 years old). The case data, changes of vital signs, detection of lesions and adverse reactions of the two groups were compared.Results:There were significant differences in combined diseases between group A and group B. The stomach examination time in group A was significantly shorter than that of group B (15.49±2.04 min VS 16.61±2.02 min, t=-2.685, P=0.009). There was significant difference in small intestine examination time between the two groups (331.69±14.96 min VS 337.83±14.28 min, t=-1.229, P=0.227). The incidence of adverse reactions in group A was significantly lower than that in group B [0.00%(0/38) VS 6.25%(4/64), χ2=6.186, P=0.013]. The changes of vital signs before, during and after examination were not statistically different. The detection rates of upper gastrointestinal lesions were 92.1% (35/38) and 98.4% (63/64), respectively. The positive rates of upper gastrointestinal bleeding under MCCG were 60.0% (21/35) and 50.8% (32/63), respectively. Patients with unexplained upper gastrointestinal bleeding under MCCG received small intestine examination. The detection rates of small intestinal lesions by small intestine examination were 84.6% (11/13) and 91.7% (22/24), respectively. Conclusion:MCCG demonstrates excellent diagnostic accuracy in elderly patients with suspected upper gastrointestinal bleeding. Additionally, it is safe and suitable for use in elderly patients with multiple comorbidities, allowing for concurrent small intestine examination.

Nerve regeneration in adult mammalian spinal cord is poor because of the lack of intrinsic regeneration of neurons and extrinsic factors - the glial scar is triggered by injury and inhibits or promotes regeneration. Recent technological advances in spatial transcriptomics (ST) provide a unique opportunity to decipher most genes systematically throughout scar formation, which remains poorly understood. Here, we first constructed the tissue-wide gene expression patterns of mouse spinal cords over the course of scar formation using ST after spinal cord injury from 32 samples. Locally, we profiled gene expression gradients from the leading edge to the core of the scar areas to further understand the scar microenvironment, such as neurotransmitter disorders, activation of the pro-inflammatory response, neurotoxic saturated lipids, angiogenesis, obstructed axon extension, and extracellular structure re-organization. In addition, we described 21 cell transcriptional states during scar formation and delineated the origins, functional diversity, and possible trajectories of subpopulations of fibroblasts, glia, and immune cells. Specifically, we found some regulators in special cell types, such as Thbs1 and Col1a2 in macrophages, CD36 and Postn in fibroblasts, Plxnb2 and Nxpe3 in microglia, Clu in astrocytes, and CD74 in oligodendrocytes. Furthermore, salvianolic acid B, a blood-brain barrier permeation and CD36 inhibitor, was administered after surgery and found to remedy fibrosis. Subsequently, we described the extent of the scar boundary and profiled the bidirectional ligand-receptor interactions at the neighboring cluster boundary, contributing to maintain scar architecture during gliosis and fibrosis, and found that GPR37L1_PSAP, and GPR37_PSAP were the most significant gene-pairs among microglia, fibroblasts, and astrocytes. Last, we quantified the fraction of scar-resident cells and proposed four possible phases of scar formation: macrophage infiltration, proliferation and differentiation of scar-resident cells, scar emergence, and scar stationary. Together, these profiles delineated the spatial heterogeneity of the scar, confirmed the previous concepts about scar architecture, provided some new clues for scar formation, and served as a valuable resource for the treatment of central nervous system injury.

【Objective】 To investigate the clinicopathological features and prognosis of clear cell papillary renal cell carcinoma (CCPRCC). 【Methods】 The clinicopathological and follow-up data of 40 CCPRCC patients treated during Jun. 2011 and Oct.2021 were retrospectively analyzed. The prognosis was compared with that of 40 cases of clear cell renal cell carcinoma (ccRCC) and 19 cases of papillary renal cell carcinoma (PRCC) treated in the same period. Survival analysis was performed by Log-rank test and Kaplan-Meier survival curves were plotted. 【Results】 Among the 40 patients, 28 were male and 12 were female, aged 31-84 years; 38 cases had unilateral and 2 cases had bilateral tumors; 3 cases had multifocal lesions. All patients received surgery. The maximum diameter of the masses ranged from 3.0 to 95.0 mm, with an average of (27.6±18.1) mm. Pathological grade was Fuhrman 1-2 in all cases. Immunohistochemical tests were positive for CK7 and CA-IX. During the follow-up of 5-129 (average 56) months, 1 case died after bone metastasis, 2 had ipsilateral recurrence, and 1 developed primary esophageal cancer. CCPRCC patients had a significantly better prognosis than CCRCC (P<0.001) and PRCC (P=0.005) patients, while there was no significant difference in the prognosis between CCRCC and PRCC patients (P=0.93). 【Conclusions】 CCPRCC has low malignancy. The diagnosis relies on characteristic pathological and immunohistochemical features. Surgery is an effective treatment. CCPRCC has a better overall prognosis than CCRCC and PRCC.

Overuse of antibiotics in medical care and animal husbandry has led to the development of bacterial antimicrobial resistance, causing increasingly more health concern. In addition to genetic mutations and the formation of resistance, the various stresses bacteria encountered in the natural environment trigger their stress responses, which not only protect them from these stresses, but also change their tolerance to antimicrobials. The emergence of antimicrobial tolerance will inevitably affect the physiological metabolism of bacteria. However, bacteria can restore their sensitivity to drugs by regulating their own metabolism. This article reviews recent studies on the relationship between bacterial stress responses or the physiological metabolism and antimicrobial tolerance, intending to take more effective measures to control the occurrence and spread of antimicrobial resistance.

Hyperuricemia/gout is a common metabolic disease in China, which is a serious threat to people′s health. In clinical practice, the standardization of prevention and diagnosis and the rate of treat-to-target need to be improved. There is still a lack of education for the patients about the understanding of clinical guidelines, the disease knowledge and the importance of cooperating with doctors to carry out diagnosis and treatment. From the most concerned issues of the patients, we established the hyperuricemia/gout patient practice guideline working group with multidisciplinary physicians and patients. Seventeen opinions, as the hyperuricemia/gout patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process, aiming to improve the patients compliance, improve the level of health management of the disease.
