Objective To analyze the effect of the activation rate of peripheral blood monocytes on the recovery of patients after liver transplantation and to initially explore the possible influencing factors for differences in monocyte activation rates. Methods A total of 139 patients who underwent orthotopic liver transplantation from September 2020 to June 2023 at Department of Liver Surgery and Transplantation of Zhongshan Hospital, Fudan University were selected. The proportion of CD14^＋HLA-DR^＋ monocytes in peripheral blood was defined as the monocyte activation rate. The difference in monocyte activation rates between postoperative day 7 (POD7) and postoperative day 1 (POD1) was calculated as Δ, and patients were divided into Δ＞0 group (n＝73) and Δ＜0 group (n＝66). The two groups were compared in terms of complete blood count, liver and kidney function, coagulation indicators, infection indicators, ICU length of stay, total length of hospitalization, and 90-day mortality. Changes in the proportions of different monocytes subsets (Mo0, Mo1, Mo2, and Mo3) and HLA-DR expression in peripheral blood on POD1 and POD7 were detected using flow cytometry. Results The ICU length of stay in the Δ＜0 group was significantly longer than that in the Δ＞0 group (18[12, 26] days vs 14[10, 20.5] days, P＝0.018). On POD1, the proportion of Mo0 in the Δ＞0 group was significantly lower than that in the Δ＜0 group (P＜0.05); on POD7, the proportion of Mo0 in the Δ＞0 group was significantly lower than that in the Δ＜0 group (P＜0.001), while the proportions of Mo1, Mo2, and Mo3 were significantly higher than those in the Δ＜0 group (P＜0.001). Compared to POD1, the HLA-DR expression level of Mo0 in peripheral blood of patients with liver transplantation significantly decreased on POD7 (P＜0.01), while there was no significant difference in HLA-DR expression levels of Mo1, Mo2, and Mo3. Conclusions Increased proportion of Mo0 (CD14^lowCD16⁻HLA-DR^low) among peripheral blood monocyte subsets may be one of the influencing factors for the differences in monocyte activation rates in patients with liver transplantation. The difference in monocyte activation rate can serve as a new clinical indicator for assessing changes in the immune status and postoperative recovery of patients with liver transplantation.

Objective: To investigate the epidemiological characteristics of pulmonary tuberculosis (PTB) among residents aged 60 years and older in Yangzhou City, Jiangsu Province from 2013 to 2022, so as to provide the evidence for the improvement of PTB prevention and control measures in this population. Methods: Data of PTB cases aged 60 years and older in Yangzhou City from 2013 to 2022 were collected from the Chinese Disease Prevention and Control Information System. The temporal, population, and regional distribution characteristics of PTB cases were analyzed using the descriptive epidemiological method. Results: A total of 8 726 PTB cases aged 60 years and older were registered in Yangzhou City from 2013 to 2022, including 4 167 cases positive for pathogenic tests, with a positive rate of 47.75%. The registered incidence rates and the positive rates of pathogenic tests of PTB among residents aged 60 years and older in Yangzhou City showed downward trends from 2013 to 2022 (both P<0.05). The average annual registered incidence rate of PTB was 83.95/105, and the average annual registered incidence rate of PTB positive for pathogenic tests was 40.09/105. The average annual registered incidence rate of PTB in males was higher than that in females (138.57/105 vs. 31.76/105, P<0.05). The registered incidence rate of PTB showed an increasing trend with age (P<0.05), with the highest rate observed in the age group of 75-<80 years (110.37/105). The top three regions with the highest average annual registered incidence rates of PTB were Jiangdu District (94.34/105), Baoying County (91.61/105) and Hanjiang District (84.93/105). Conclusions The registered incidence of PTB among residents aged 60 years and older in Yangzhou City showed a downward trend from 2013 to 2022. Particular attention should be payed to males, residents aged 75- <80 years, and the elderly in Jiangdu District and Baoying County.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Objective　To analyse the crude detection rate and trends of newly detected HIV/AIDS cases in medical institutions in China from 2017 to 2023, and to provide a reference for optimizing HIV testing strategies in medical institutions. Methods　Data on HIV testing and newly reported HIV/AIDS cases were analysed using data from the Comprehensive AIDS Prevention and Control Information System of the China Information System for Disease Control and Prevention for the period from 2017 to 2023. HIV testing in medical institutions includes patients tested preoperatively, those tested before transfusion, those tested in sexually transmitted disease (STD) clinics, prenatal care clinics, and other types of patients. Descriptive statistical analysis and χ2 test were performed using SAS 9.4 software. Joinpoint regression was performed using Joinpoint 4.9.0 software to analyse trends of the crude detection rates over time. Results　From 2017 to 2023, the person-times of HIV tests in medical institutions increased from 143 million to 255 million, with an increase of 78.07%. The number of newly detected HIV/AIDS cases increased from 74 000 to 88 000 and then declined to 69 000. The crude detection rate of new HIV/AIDS cases declined from 5.18/10 000 to 2.71/10 000, showed a declining trend, the mean annual percentage change was -9.99%(P<0.001). The crude detection rate of new HIV/AIDS cases in STD clinics was the highest among all types of clinic visits (12.79/10 000-24.47/10 000), and the crude detection rate of new cases among all types of clinic visits showed a decreasing trend(P<0.05). Among different medical institutions, general hospitals were the most important source of the number of tests and the number of newly detected HIV/AIDS cases, accounting for more than 62.93% and 62.68%, respectively. Specialised medical institutions had the highest crude detection rate of new cases, which was maintained at more than 5.13/10 000. The crude detection rate of new cases for all four types of medical institutions, except for primary medical institutions, showed a decreasing trend (P<0.05). Conclusions　The detection rate of new cases in medical institutions showed a decreasing trend in 2017-2023, and the efficiency of STD clinics testing and detection was higher among all types of attendees. General hospitals are the main source of new cases detection, and testing in specialised medical institutions is more efficient. Testing should be strengthened in key groups of patients and in key medical institutions.

Objective: To investigate the current status and influencing factors of overweight and obesity among adults in Jiaxing City, Zhejiang Province, so as to provide a basis for developing targeted weight management measures. Methods: In 2024, a multistage stratified random cluster sampling method was employed to recruit permanent residents aged ≥18 years from Jiaxing City for questionnaire surveys. Data on basic information, lifestyle behaviors, and history of chronic diseases were collected. Height and body weight were measured, and overweight and obesity were determined based on body mass index (BMI). The influencing factors of overweight and obesity among adults were analyzed by a multivariable logistic regression model. Results: Totally 10 509 questionnaires were allocated, and 9 802 valid questionnaires were recovered, with an effective recovery rate of 93.27%. Among the respondents, 4 808 (49.05%) were males and 4 994 (50.95%) were females, with a mean age of (51.27±17.26) years. A total of 4 884 overweight and obesity individuals were identified, with a detection rate of 49.83%. Multivariable logistic regression analysis showed that gender (male, OR=1.719, 95%CI: 1.578-1.873), age (≥60 years, OR=0.802, 95%CI: 0.652-0.986), educational level (bachelor and above, OR=0.640, 95%CI: 0.518-0.791), marital status (being married/cohabiting, OR=1.224, 95%CI: 1.009-1.486), adequate nut intake (OR=0.910, 95%CI: 0.832-0.995), hypertension (OR=2.462, 95%CI: 2.219-2.732), and dyslipidemia (OR=1.629, 95%CI: 1.444-1.837) were statistically associated with overweight and obesity among adults. Conclusion The detected rate of overweight and obesity among adults in Jiaxing City was relatively high, and was mainly associated with gender, age, education level, marital status, nut intake, hypertension, and dyslipidemia.

Platycodonis Radix is the dry root of Platycodon grandiflorum of Campanulaceae, which has a variety of pharmacological effects and is a commonly used bulk Chinese medicine. In this study, the chloroplast genome sequences of six P. grandiflorum from different producing areas has been sequenced with Illumina HiSeq X Ten platform. The specific DNA barcodes were screened, and the germplasm resources and genetic diversity were analyzed according to the specific barcodes. The total length of the chloroplast genome of 6 P. grandiflorum samples was 172 260-172 275 bp, and all chloroplast genomes showed a typical circular tetrad structure and encoded 141 genes. The comparative genomics analysis and results of amplification efficiency demonstrated that trnG-UCC and ndhG_ndhF were the potential specific DNA barcodes for identification the germplasm resources of P. grandiflorum. A total of 305 P. grandiflorum samples were collected from 15 production areas in 9 provinces, for which the fragments of trnG-UCC and ndhG_ndhF were amplificated and the sequences were analyzed. The results showed that trnG-UCC and ndhG_ndhF have 5 and 11 mutation sites, respectively, and 5 and 7 haplotypes were identified, respectively. The combined analysis of the two sequences formed 13 haplotypes (named Hap1-Hap13), and Hap4 is the main genotype, followed by Hap1. The unique haplotypes possessed by the three producing areas can be used as DNA molecular tags in this area to distinguish from the germplasm resources of P. grandiflorum from other areas. The haplotype diversity, nucleotide diversity and genetic distance were 0.94, 4.79×10^-3 and 0.000 0-0.020 3, respectively, suggesting that the genetic diversity was abundant and intraspecific kinship was relatively close. This study laid a foundation for the identification of P. grandiflorum, the protection and utilization of germplasm resources, and molecular breeding.

Objective To establish a rapid and convenient UPLC-MS/MS method for the determination of tamoxifen and its active metabolite endoxifen in plasma of patients with breast cancer.Methods With diazepam as the internal standard,the plasma sample was precipitated with acetonitrile and methanol-acetonitrile was used as mobile phase.The samples were separated by chromatographic column ZORBAX Eclipse plus C18(18 μm,2.1 mm x50 mm)and scanned by electrospray ion source and positive ion multiple reaction monitoring mode.The ion channels were detected as tamoxifen m/z 372.0→72.1,endoxifen m/z 374.0→58.2 and diazepam m/z 285→192.9.Results The linearity of tamoxifen and endoxifen were good in the concentration range of 1-500 ng·mL-1(R2=0.999 5)and 0.5-250 ng·mL-1,respectively(R2=0.999 9).The intra-day and inter-day precision of low,medium and high quality control concentrations were all less than 10％.Tamoxifen and endoxifen were stable at low temperature and stable after repeated freeze-thaw.Conclusion The experimental results show that the method meets the requirements of biological sample analysis,and the sample treatment is simple,specific,and can be used for the accurate and rapid determination of tamoxifen and indoloxifen in human plasma.

Objective To compare the efficacy and safety of empagliflozin and linagliptin in the treatment of patients with type 2 diabetes mellitus(T2DM)with heart failure(HF).Methods Patients with T2DM and HF were randomly into control group and treatment group.Both groups were treated with individualized anti-HF and metformin-based hypoglycemic therapy.On this basis,the control group was given linagliptin orally(5 mg each time,once a day),while the treatment group was given oral administration of empagliflozin 10 mg every day.Patients in both groups were treated continuously for 6 months.The clinical efficacy and blood glucose indicators[fasting blood glucose(FBG),2 h postprandial blood glucose(2 h PBG),hemoglobin A1c(HbA1c)],cardiac molecular markers[N-terminal pro-brain natriuretic peptide(NT-proBNP),fibroblast growth factor 23(FGF23),copeptin(CPP)]and caridac function indicators[left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),left ventricular remodeling index(LVRI)]before and after treatment were compared,and the adverse drug reactions were recorded.Results There were 40 cases in treatment group and 40 cases in control group.After treatment,the total effective rates in treatment group and control group were 97.50％(39 cases/40 cases)and 80.00％(32 cases/40 cases),with no significant difference(P＜0.05).The FBG levels in treatment group and control group were(7.64±1.18)and(7.83±1.24)mmol·L-1;2 h PBG levels were(8.97±1.46)and(9.04±1.35)mmol·L-1;HbA1c levels were(7.58±1.27)％and(7.65±1.42)％,all with no significant difference(all P＞0.05).The NT-proBNP levels in treatment group and control group were(612.53±204.62)and(1 045.24±316.75)pg·mL-1;FGF23 levels were(362.74±62.61)and(493.27±74.64)μg·L-1;CPP levels were(12.58±3.43)and(16.87±4.36)pmol·L-1;LVEDD values were(51.19±2.36)and(53.35±2.24)mm;LVEF values were(52.69±3.38)％and(50.28±3.75)％;LVRI values were(2.62±0.29)and(2.96±0.33)kg·L-1,all with significant difference(all P＜0.05).The incidence rates of adverse reactions in treatment group and control group were 5.00％(2 cases/40 cases)and 10.00％(4 cases/40 cases),with no significant difference(P＞0.05).Conclusion Both empagliflozin and linagliptin can effectively reduce the blood glucose in patients with T2DM complicated with HF.Empagliflozin can better promote the improvement of cardiac function in patients without significantly increase the incidence of adverse drug reactions.
