The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Objective : To investigate the diagnostic value of plasma calprotectin in childern with refractory mycoplasma pneumoniae pneumonia(RMPP). Methods : A multicenter, prospective cohort study was conducted, enrolling 228 children with mycoplasma pneumoniae pneumonia(MPP). Among these, 177 cases were diagnosed with general mycoplasma pneumoniae pneumonia(GMPP), while the remaining 51 cases were RMPP. Plasma was collected at the time of admission of the children in both groups, and calprotectin levels were measured. A one-way difference analysis was performed on the blood test indexes of the children in the two groups, and the difference variables withP<0.05 between the two groups were included in a multifactorial logistic regression to analyze the risk factors for the progression of GMPP to RMPP. The differential diagnostic value of plasma calprotectin for GMPP and RMPP was analyzed by the receiver operating characteristic(ROC) curves. Results : Univariate analysis showed that plasma calprotectin levels were significantly higher in the RMPP group than those in the GMPP group, and the difference was statistically significant(P<0.05). Logistic regression analysis showed that plasma calprotectin was an independent risk factor for RMPP(OR=1.323,P<0.001), ROC curve analysis showed that plasma calprotectin had a higher diagnostic value for the differential diagnosis of GMPP and RMPP(AUC =0.839), and its combination with C-reactive protein and albumin could significantly improve the diagnostic efficiency. Conclusion Plasma calprotectin has good clinical value for the diagnosis of RMPP.

Objective:To explore the clinical characteristics and molecular basis for children and adolescents with monogenic diabetes.Methods:A retrospective analysis was carried out for the clinical manifestations and laboratory data of 116 children and adolescents diagnosed with diabetes at Ningbo Women and Children′s Hospital from January 2020 to March 2023. Whole exome sequencing and mitochondrial gene sequencing were carried out on 21 children with suspected monogenic diabetes.Results:A total of 10 cases of monogenic diabetes were diagnosed, all of which were Maturity-onset Diabetes Of the Young (MODY). Six cases of MODY2 were due to GCK gene mutations, 1 case of MODY3 was due to HNF1A gene mutation, 2 cases of MODY12 were due to ABCC8 gene mutations, and 1 case of MODY13 was due to KCNJ11 gene mutation. Nine of the 10 patients with MODY had no typical symptoms of diabetes. A family history of diabetes was significantly more common in the MODY group compared with the T1DM and T2DM groups ( P<0.05). The BMI of the MODY group was higher than that of the T1DM group ( P<0.05). The initial blood glucose level was lower than that of the T1DM group ( P<0.05), and there was no significant difference compared with the T2DM group. The fasting C-peptide level of the MODY group was higher than that of the T1DM group ( P<0.05), and there was no significant difference compared with the T2DM group. Glycosylated hemoglobin of the MODY group was lower than both the T1DM and T2DM groups ( P<0.05). Conclusion:In this study, MODY has accounted for the majority of monogenic diabetes among children and adolescents, and the common mutations were those of the GCK gene in association with MODY2. Blood glucose and glycosylated hemoglobin of children with MODY were slightly increased, whilst the islet cell function had remained, and the clinical manifestations and laboratory tests had overlapped with those of type 2 diabetes. WES and mitochondrial gene sequencing can clarify the etiology of monogenic diabetes and facilitate precise treatment.

Objective:To describe the epidemiological characteristics and trends of leukemia incidence in Qidong between 1972 and 2021, and provide guidelines for prevention and control measures and strategies.Methods:The cancer registry data was collected and analyzed on leukemia incidence during 1972—2021 in Qidong by sex, age and time. Crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), and average annual change percentage (AAPC) was calculated by Joinpoint software. Age-period-cohort (APC) model was used to analyze the influence of age, period and birth cohort on the changes in the incidence trend of leukemia patients.Results:From 1972 to 2021, there were 2 948 patients with leukemia in Qidong, accounting for 2.00% of all cancer new cases, CR of leukemia was 5.26/10 5, ASRC was 4.34/10 5, ASRW was 4.35/10 5. The truncated incidence of 35—64 years old was 5.29/10 5, the cumulative incidence rate between the ages of 0 and 74 years old was 0.40%, the cumulative risk was 0.40%. There were 1 608 male patients, the CR, ASRC, and the ASRW were 5.81/10 5, 4.88/10 5 and 4.85/10 5. The number of female patients were 1 340, and the CR, ASRC, and the ASRW were 4.71/10 5, 3.86/10 5 and 3.91/10 5, respectively. Temporal trends indicated significant upward trends in ASRC among both gender, males and females with AAPC values of 1.41% ( P＜0.001), 1.15% ( P＜0.001), and 1.73% ( P＜0.001), respectively. The results of the APC model showed that the average net drift value of leukemia incidence in all age groups was 1.57% (95% CI, 1.24%-1.89%), and the highest value of local drift was 3.20% (95% CI, 1.63%-4.78%) in the 80~ years old group. The incidence of leukemia increased with age. With the passage of time, the risk of leukemia incidence increased gradually compared with the rate ratio of leukemia incidence (risk ratio [ RR], 1.00) in 1992—1996, the RR of leukemia incidence increased from 0.70 during 1972—1976 to 1.57 during 2017—2021. The later the cohort was born, the greater the risk of leukemia incidence compared with the relative risk of leukemia incidence ( RR, 1.00) in 1952—1956 cohort, the RR of leukemia incidence increased from 0.24 in the 1892—1896 cohort to 2.73 in the 2017—2021 cohort. Conclusions:The incidence of the leukemia has presented a rising trend in the past fifty years. Leukemia incidence increased with age, and the period and cohort effects on the risk of incidence increase. Further research is needed to investigate the risk factors related to leukemia.

Objective To analyze the trend of heart disease death and the life expectancy without cause of death in Qidong City, Jiangsu Province from 1990 to 2019, and to provide reference for the prevention and control of heart disease. Methods Data on heart disease deaths among residents in Qidong City from 1990 to 2019 were collected through the Qidong City Death Registration and Monitoring System. The crude mortality rate (CR) and Chinese age-standardized mortality rate (CASR), potential years of life loss (PYLL), average years of life loss (AYLL), potential life loss years rate (PYLLR), life expectancy, and life expectancy without cause of death were calculated, and the annual percentage change (APC) was used to analyze the trend of heart disease death. Using SAS9.2 software, the death trend prediction was conducted by the ARIMA model in time series analysis. Results From 1990 to 2019, 27,762 residents died of heart disease in Qidong City, with a CR of 81.20/100 000 and an APC of 3.734%. There were 12 358 deaths of heart disease in men, with a CR of 73.24/100 000 and an APC of 3.86%, while there were 15 404 deaths of heart disease in women, with a CR of 88.95/100 000 and an APC of 3.63%. CR showed an upward trend (all P < 0.001). The PYLL for heart disease was 66 192.00 person-years, the AYLL was 13.23 person-years, and the PYLLR was 2.16‰. The life expectancy loss from heart disease was gradually increasing: 0.89 years in 1990 to 1.85 years in 2019, with an APC of 0.405% (P<0.001, a statistically significant trend). The prediction results showed that in 2029, the life expectancy after heart disease would reach 88.17 years. Conclusion From 1990 to 2019, the crude mortality rate of heart disease in Qidong City has showed an increasing trend, leading to an increasing loss of life due to heart disease year by year. The mortality rate and life loss of heart disease in women are higher than those in men. Targeted intervention measures should be further adopted to reduce the mortality rate of heart disease among residents in Qidong.

Wound infections, secondary to acute and chronic wounds caused by mechanical, thermal, chemical factors, etc, not only delay wound healing but also may lead to mortality. The prolonged or inappropriate use of antibiotics lead to the growth of drug-resistant bacteria, resulting in refractory wound infections and poor treatment outcomes, which highlights the urgent need for effective therapies. Bacteriophages show great promise in treating drug-resistant wound infections due to their effectiveness in killing drug-resistant bacteria, their good resistance against bacterial biofilm (BBF) and their absence of cytotoxicity to eukaryotic cells. However, the mechanisms underlying bacteriophages′ resistance against BBF remain incompletely understood and their antibacterial efficacy for wound infections may also vary. For this purpose, the authors reviewed the biological characteristics and mechanisms of bacteriophages and their application in antibacterial therapies for wound infections, aiming to provide a reference for further research and application of bacteriophages in the treatment of wound infections.

Triple-negative breast cancer (TNBC) represents a distinct subtype of breast cancer, characterized by unique clinical traits including early lung metastasis, elevated recurrence rates, and diminished survival prospects. Owing to the lack of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression, concrete therapeutic targets remain elusive, thereby confining available clinical treatment methods. In the context of advanced TNBC, chemotherapy remains the predominant therapeutic approach. In recent years, with the in-depth study of tumor microenvironment, new immunotherapy targets have been discovered one after another. Thus, immunotherapy-based combined therapy strategies have brought new hope in patients with advanced TNBC.

Objective: To investigate the survival rate and changing trends of kidney cancer patients in Qidong City from 1972 to 2016, so as to provide insights into kidney cancer control. Methods: Data pertaining to the incidence of kidney cancer in Qidong City from 1972 to 2016 were captured from the Qidong Municipal Cancer Registration System, and the final follow-up period was December 31, 2021. The observed survival rate, relative survival rate and standardized relative survival rate of kidney cancer were calculated to analyze the survival of kidney cancer, and the trends in survival were analyzed among kidney cancer patients from 1972 to 2016 using annual percent change (APC). Results: A total of 554 kidney cancer patients were reported in Qidong City from 1972 to 2016. The 1-, 3- and 5-year observed survival rates, relative survival rates and standardized relative survival rates were 62.27%, 50.54% and 44.04%; 64.31%, 55.71% and 51.93%; and 61.71%, 51.90%, and 51.68%, respectively. The 5-year observed survival rate, relative survival rate and standardized relative survival rate of kidney cancer appeared a tendency towards a rise in Qidong City from 1972 to 2016, with APC of 2.83% (t=4.303, P=0.004), 2.82% (t=3.978, P=0.005) and 3.96% (t=5.898, P=0.001), and the 5-year relative survival rate of kidney cancer was comparable between men and women (53.05% vs. 50.40%; χ2=4.872, P=0.676). There was an age-specific 5-year relative survival rate of kidney cancer (χ2=35.144, P<0.001), with the greatest among patients at ages of 35 to 44 years (64.49%) and the lowest at ages of 75 years and older (30.11%). Conclusion The 5-year survival rate of kidney cancer cases appeared a tendency towards a rise in Qidong City from 1972 to 2016. Further specific interventions, depending on age, are needed for management of kidney cancer.

OBJECTIVE: To analyze the clinical characteristics and risk factors of early acute liver injury in patients with heat stroke (HS), and to provide basis for early identification of HS-related liver injury and its pathogenesis in clinical practice. METHODS: The clinical data of patients with HS admitted to the department of critical care medicine of Haian People's Hospital from June 2015 to August 2022 were retrospectively analyzed. The patients with HS were divided into early liver injury group and early non-liver injury group according to the occurrence of acute liver injury within 24 hours of admission. The differences of basic data, clinical data, laboratory indexes and clinical outcomes of the two groups were analyzed. Logistic regression was used to analyze the risk factors for early HS-related acute liver injury, and receiver operator characteristic (ROC) curves were drawn to evaluate their value in predicting the occurrence of early HS-related acute liver injury. RESULTS: A total of 76 patients with HS were enrolled, and 46 patients with acute liver injury, accounting for 60.53%. In the early liver injury group, 14 patients (30.43%) had elevated aminotransferase alone, 9 patients (19.57%) had elevated total bilirubin (TBil) alone, and 23 patients (50.00%) had elevated both aminotransferase and TBil. Among the patients with elevated aminotransferases, 24 patients (64.87%) had mild elevation, 5 patients (13.51%) had moderate elevation, 8 patients (21.62%) had severe elevation. Compared with the early non-liver injury group, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), arterial blood lactate (Lac), interleukin-6 (IL-6), procalcitonin (PCT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), TBil, γ-gamma glutamyl transferase (γ-GGT), lactate dehydrogenase (LDH), creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), cardiac troponin I (cTnI), myoglobin (MYO), N-terminal B-type pro-brain natriuretic peptide (NT-proBNP), prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer in the early liver injury group were significantly increased, while platelet count (PLT) were significantly decreased within 24 hours after admission, the 28-day mortality was significantly increased [28.26% (13/46) vs. 6.67% (2/30)], and the differences were statistically significant (all P < 0.05). Univariate Logistic regression analysis showed that APACHE II score, SOFA score, PLT, Lac, IL-6, PCT, γ-GGT, LDH, CK, CK-MB, cTnI, MYO, PT, APTT, D-dimer were risk factors of early HS-related acute liver injury (all P < 0.05). Multivariate Logistic regression analysis showed that PLT, IL-6, and LDH were independent risk factors of early HS-related acute liver injury [odds ratio (OR) and 95% confidence interval (95%CI) were 0.986 (0.974-0.998), 1.027 (1.012-1.041), and 1.002 (1.000-1.004), all P < 0.05]. The ROC curve analysis showed that the area under the ROC curve (AUC) of PLT, IL-6 and LDH for predicting the occurrence of early HS-related acute liver injury was 0.672 (95%CI was 0.548-0.797), 0.897 (95%CI was 0.824-0.971) and 0.833 (95%CI was 0.739-0.927), respectively. IL-6 had the highest predictive value for early HS-related liver injury. When the optimal diagnostic threshold of IL-6 was 48.25 ng/L, the sensitivity was 95.7%, the specificity was 73.3%, and the predictive value of PLT was the lowest. CONCLUSIONS The early HS-related liver injury is mainly manifested as the simultaneous elevation of aminotransferase and TBil, and most of cases are mild liver injury. PLT, IL-6 and LDH are independent risk factors of early HS-related acute liver injury.
