Objective To investigate the clinical characteristics,diagnosis and treatment of ileal injury secondary to percutaneous nephrolithotomy percutaneous nephrolithotomy(PCNL).Methods The diagnosis and treatment of a patient were reviewed,and relevant literature were retrieved.Results The patient was a 41-year-old male,who underwent stage PCNL(initial percutaneous nephrostomy,followed by secondary PCNL)due to right ureteral calculi with severe hydronephrosis.On postoperative day 1,he developed abdominal distension and pain.Abdominal X-ray revealed subdiaphragmatic free gas,and CT showed pelvic and abdominal fluid and gas accumulation,suggesting peritonitis due to intestinal perforation.Emergency exploratory laparotomy identified a 3 mm×3 mm ileal perforation approximately 30 cm from the ileocecal valve,which was repaired surgically.The patient recovered well and was discharged after one week,with no discomfort reported during a 6-month follow-up.Conclusion The clinical features of ileal injury secondary to PCNL include early postoperative abdominal distension,pain and peritonitis.Diagnosis relies on clinical manifestations,abdominal X-ray and CT,with surgical exploration if necessary.Conservative management under vigilant observation can be cautiously adopted for localized injuries,while surgical repair is required for peritonitis or failed conservative therapy.

Background::Hepatitis B poses a heavy burden for children in China, however, the national studies on the distributional characteristics and health care costs of children with severe hepatitis B is still lacking. This study aimed to analyze the disease characteristics, health economic effects, and medical cost for children with severe hepatitis B in China.Methods::Based on patient information in the Hospital Quality Monitoring System, cases with severe hepatitis B were divided into four groups according to age, and the etiology and symptoms of each group were quantified. The cost of hospitalization was calculated for cases with different disease processes, and severity of disease. The spatial aggregation of cases and the relationship with health economic factors were analyzed by Moran’s I analysis. Results::The total number of children discharged with hepatitis B from January 2016 to April 2022 was 1603, with an average age of 10.5 years. Liver failure cases accounted for 43.48% (697/1603) of total cases and cirrhosis cases accounted for 11.23% (180/1603). According to the grouping of disease progression, there were 1292 cases without associated complications, and the median hospitalization cost was $818.12. According to the spatial analysis, the aggregation of cases was statistically significant at the prefectural and provincial levels in 2019, 2020, and 2021 (all P <0.05). The number of severe cases was negatively correlated with gross domestic product (Moran’s I <0) and percentage of urban population (Moran’s I <0), and positively correlated with the number of pediatric beds per million population (Moran’s I >0). Conclusion::The number of severe hepatitis B cases is low in areas with high gross domestic product levels and high urban population ratios, and health care costs have been declining over the years.

Hemoglobin A1c (HbA1c) has a unique structure that makes monoclonal antibody (mAb) preparation challenging. This study aims to develop a method for preparing HbA1c mAbs and establish a fluorescent immunochromatographic assay (FICA) for rapid detection of HbA1c. Three glycosylated peptides were synthesized and used to prepare complete antigens, which were identified by dot enzyme-linked immunosorbent assay (Dot-ELISA) and ultraviolet absorption spectroscopy. The complete antigens and natural HbA1c were used for cross-immunization of mice, and the optimal complete antigen was selected. The mouse with the highest serum titer was chosen for mAb preparation. The purity and specificity of the mAbs were verified, and a FICA method was developed. The optimal complete antigen, with a titer of 1:512 000, was successfully prepared and selected. Fusion with splenocytes resulted in four specific HbA1c antibodies (purity > 90%). The best antibody exhibited a binding constant (Ka) of 1.67×10¹⁰ L/mol with the antigen. Based on this antibody, a FICA method was successfully established, capable of producing results within 15 min. The method demonstrated a good linear range (3%-13% HbA1c, y=0.071 3x+0.005 6, R²=0.993 7), recovery rates of 98%-102%, precision < 10.00%, and no nonspecific reactions. Clinical testing of 210 samples showed positive agreement of 96.36%, negative agreement of 97.00%, and overall agreement of 96.68%. The receiver operating characteristic (ROC) curve analysis yielded an area under curve (AUC) of 0.980 9 [95% confidence interval (CI): 0.961 0-1.000 0], with high consistency verified in multicenter studies. We successfully developed a key technique for preparing HbA1c monoclonal antibodies and established a FICA method for rapid detection of HbA1c. It will provide an efficient and convenient detection method for the early diagnosis and long-term management of diabetes and its complications.

The theory of "holism of five organs" highly encapsulates the understanding of TCM on the integrity, connectivity, and unity of the internal life functions and morphological structures of the human body. Functional gastrointestinal disorders (FGIDs) frequently overlap, and TCM has significant advantages in their prevention and treatment based on the theory of the holistic view and syndrome differentiation and treatment. Exosomes are extracellular vesicles whose secretory form and biological functions fully reflect the "holism of five organs", and they are of great value in the pathogenesis, diagnosis and treatment of overlap of symptoms of FGIDs. This article interpreted the relationship between exosomes and overlap of symptoms of FGIDs with the "holism of five organs", aiming to provide new ideas and methods for the prevention and treatment of overlap of symptoms of FGIDs, as well as partly explain the scientific connotation of the theory of "holism of five organs".

The pathogenesis of ulcerative colitis(UC)is still unclear,and the pathogenesis based on intestinal mucosal immune imbalance is now widely recognized."Spleen as the defense"refers to the function of the spleen to protect the body and defend against pathogenic factors,which is highly consistent with modern mucosal immunology theory.The abnormal function of"Spleen as the defense"is the key reason for the immune imbalance of UC intestinal mucosa.In this paper,"spleen as the defense"as the starting point,to explore the mechanism of UC intestinal mucosal immune dysfunction,to consolidate the theoretical basis for the treatment of UC based on spleen,and to provide a theoretical basis for the treatment of UC from the perspective of restoring intestinal mucosal immune homeostasis.

Objective The occurrence of chickenpox in rapidly developing areas poses substantial seasonal risk to children.However,certain factors influencing local chickenpox outbreaks have not been studied.Here,we examined the relationship between spatial clustering,heterogeneity of chickenpox outbreaks,and socioeconomic factors in Southern China. Methods We assessed chickenpox outbreak data from Southern China between 2006 and 2021,comprising both relatively fast-growing parts and slower sub-regions,and provides a representative sample of many developing regions.We analyzed the spatial clustering attributes associated with chickenpox outbreaks using Moran's I and local indicators of spatial association and quantified their socioeconomic determinants using Geodetector q statistics. Results There were significant spatial heterogeneity in the risk of chickenpox outbreaks,with strong correlations between chickenpox risk and various factors,particularly demographics and living environment.Furthermore,interactive effects among specific are factors,such as population density and per capita residential building area,percentage of households with toilets,percentage of rental housing,exhibited q statistics of 0.28,0.25,and 0.24,respectively. Conclusion This study provides valuable insights into the spatial dynamics of chickenpox outbreaks in rapidly developing regions,revealing the socioeconomic factors affecting disease transmission.These implications extend the formulation of effective public health strategies and interventions to prevent and control chickenpox outbreaks in similar global contexts.
