Objective To investigate the drug resistance phenotype/genotype and virulence gene carrying status, serotype, and sequence typing (ST) of Campylobacter jejuni in Fengtai District in 2024. Methods The drug resistance phenotype was detected by agar dilution method, and serotyping was performed by real-time fluorescence quantitative polymerase chain reaction (PCR). The whole genome sequencing was used to analyze drug resistance genes, virulence genes, and other characteristics. Results Among the 35 Campylobacter jejuni strains analyzed, the antibiotics with the highest resistance rates were nalidixic acid and ciprofloxacin (both 82.86%), followed by tetracycline (74.89%). All strains exhibited a 100.00% sensitivity rate to erythromycin. The multiple drug resistance rate was 77.14%. The predominant drug resistance genes were gyrA-T86I (94.29%) and tetO (74.29%). The most common serotype was HS:2, accounting for 25 strains. A total of 132 virulence genes were detected. There were 12 clonal complexes (CC) and 24 ST types. Conclusion The drug resistance situation of Campylobacter jejuni in Fengtai District is relatively severe, and the drug resistance phenotype is related to specific genetic mutations to some extent. The serotypes are diverse, the virulence genes are complex, and the pathogenic potential is significant, posing a notable risk for inducing Guillain-Barré syndrome (GBS). The high number of ST types indicates substantial genetic diversity.

Chemotherapy-induced peripheral neuropathy(CIPN)refers to some symptoms and signs of peripheral nerve dysfunc-tion caused by using anti-tumor drugs,which is related to the dose of chemotherapy drugs.The pathogenesis of CIPN has not been fully defined,and the efficacy of existing therapeutic drugs and methods is limited.Therefore,it is of great scientific value and social significance to explore the pathogenesis of CIPN,de-velop new therapeutic drugs and methods,and solve the unmet clinical needs.This paper will elaborate on the pathogenesis of CIPN from the molecular and cellular levels,and review the treatment progress of CIPN,so as to provide reference for clinical treatment and direction for future research.

Objective To analyze the correlation between lesion volume,lesion mass,and maximum lesion diameter in the assessment of advanced hepatocarcinoma with lung metastasis,and to evaluate the application value of total volume response and total mass response of lung metastatic lesions in efficacy assessment.Methods A retrospective analysis was conducted on the CT imaging data of 20 patients clinically confirmed with hepatocarcinoma and lung metastases,followed by subsequent follow-up to monitor their survival outcomes.Volume measurement software was used to measure the volume of lesions before and after treatment.We recored lesion diameter,volume measurements and CT values,calculated the mass of the lesions.The correlation between lesion volume,mass and diameter was analyzed,as well as the correlation between the change rates of volume,mass and lesion diameter.Additionally,the total volume and total mass of all lesions were calculated.The correlation between the change rates of total volume/total mass and the change rate of pulmonary lesion diameter under the RECIST 1.1 criteria,as well as the correlation with changes in patients'tumor markers,were analyzed.Furthermore,the overall volume response and overall mass response of lesions were evaluated based on changes in total volume and total mass,and their consistencies with the RECIST 1.1 criteria for efficacy evaluation were analyzed.Finally,univariate Cox regression analysis was performed to explore the association between these variables and patient survival outcomes.Results There was strong correlation between lesion volume,mass and tumor diameter(r=0.771,0.775),between the rate of change in mass and the rate of change in lesion diameter(r=0.846),and between the rates of change in total volume/total mass and the rate of change in pulmonary lesion diameter under the RECIST 1.1 criteria(r=0.800,0.896).The correlation between the rates of change in total volume/total mass and patients'tumor markers was not statistically significant.There was moderate correlation between the rate of change in volume and the rate of change in lesion diameter(r=0.692).The evaluation results of total volume response and total mass response for pulmonary lesions in advanced hepatocarcinoma with lung metastasis were generally consistent with the RECIST 1.1 criteria(Kappa=0.486,0.426).Univariate Cox regression analysis revealed that total lesion volume(P=0.047)and total lesion mass(P=0.049)were independent prognostic factors for survival outcomes.Conclusion Lesion volume,mass,and diameter,as well as their respective change rates,were found to be interrelated.Furthermore,total lesion volume and total lesion mass were identified as independent prognostic factors for survival outcomes.The total volume response and total mass response are promising evaluation methods in evaluating the efficacy of lung metastasis of hepatocarcinoma,which are different from the RECIST 1.1 evaluation criteria.

Objective To analyze the value of phase angle(PA)measured by bioelectrical impedance analysis in evaluating nutritional status of peritoneal dialysis(PD)patients.Methods Totally 271 patients admitted to the Department of Nephrology,Tenth People's Hospital Affiliated to Tongji University from April 2020 to December 2021 were selected.InBody S10(Korean Biospace)was used to detect PA at 50kHz,which was divided into normal PA group and low PA group.The differences of general data and laboratory indexes between the two groups were compared,and the relationship between PA and each index was analyzed by Pearson correlation analysis and multiple linear regression analysis.Results Among 271 PD patients,108(39.9％)were in the normal PA group and 163(60.1％)were in the low PA group.The proportion of diabetic nephropathy patients in low PA group was significantly higher than that in normal PA group.Pearson correlation analysis showed that PA was negatively correlated with age,glycated hemoglobin,neutrophil to lymphocyte ratio(NLR),percent body fat(PBF),edema index and visceral fat area(VFA).It was positively correlated with creatinine,prealbumin,albumin,predictive nutritional index(PNI),25-hydroxyvitamin D3[25(OH)D3],serum iron,fat free mass,skeletal muscle mass,arm muscle circumference(AMC),bone mineral content,VFA,basal metabolic rate and skeletal muscle mass index(SMI)(P＜0.05).Multiple linear regression analysis showed that creatinine,NLR,AMC,SMI were independently correlated with PA.Conclusions Bioelectrical impedance analysis(BIA)is non-invasive and rapid to evaluate the nutritional status of patients.Early identification of patients'nutritional status and implementation of individualised nutritional interventions are important ways to improve the quality of life and survival of patients with renal failure.

Background The retail milk tea industry is in a period of rapid development, but there is little research on its nutrient content, which restricts the nutritional guidance of milk tea. Objective To determine the levels of nutrients in best-selling handcrafted milk tea in Shanghai and analyze the nutritional characteristics. Methods In 2018 and 2021, a total of 13 handcrafted milk tea brands with ≥3 branch stores in Shanghai were selected by searching for milk tea on Meituan and Ele.me food delivery platforms, and a total of 122 types of handcrafted milk tea products were collected from the top three sales [milk tea (including all sweetness levels available), milk cover tea, and fruit tea]. National standard methods were used to detect energy, protein, fat, carbohydrate, sugar, trans fatty acid, calcium, caffeine, and tea polyphenol. Results The median energy of the milk tea samples was 310 kJ (per 100 g sample). The main sources of energy were carbohydrate and fat. The levels of energy, protein, and fat in milk cover tea and milk tea were significantly higher than those in fruit tea (P＜0.05), and there was no significant difference in carbohydrate among them. The total sugar, fructose, and glucose levels in milk tea were significantly lower than those in milk cover tea and fruit tea, and the lactose level in fruit tea was significantly lower than those in milk tea and milk cover tea (P＜0.05). Themedian trans fat acid level in milk cover tea was higher than that in milk tea (P＜0.05). The median levels of caffeine and tea polyphenol were higher in milk tea than in milk cover tea (P＜0.05). The levels of energy, carbohydrate, sucrose, total sugar, and calcium in milk tea were positively correlated with the number of ingredients added (0-3) (r=0.386, 0.371, 0.238, 0.698, 0.466, respectively, P < 0.05). The levels of energy, carbohydrate, and total sugar tended to increase with increasing sweetness (P<0.05), and total sugar was mainly sucrose, followed by fructose and glucose. The total sugar levels of the samples labeled sugar free, light sugar, half sugar, less sugar, and regular sugar were 3.40 (2.20, 4.9), 4.97 (4.25, 5.97), 5.80 (4.31, 6.88), 6.59 (5.17, 8.53), and 7.96 (6.82, 9.20) g, respectively; the proportions of the samples containing more than 0.5 g of total sugar were 93.3% for sugar free milk tea, 47.4% for light sugar milk tea, and 94.0% for regular sugar milk tea; the proportion of the regular sugar samples with sugar content greater than 10 g was 18.0% (all samples with nominal sugar content were measured per 100 g). Conclusion The retail handcrafted milk tea in Shanghai is characterized by high energy, high added sugar, high fat, and low protein. It is necessary to standardize the added sugar content and sweetness labeling, strengthen the nutrition education of milk tea, and guide residents to limit its intake.

Background Children and adolescents drink sugar-sweetened beverages (SSBs) frequently. Research has confirmed that SSBs associate with weight gain and overweight or obesity. However, it is unclear whether high SSBs intake associates with abnormal changes in physical growth and glucolipid metabolism before causing adverse health outcomes such as overweight and obesity. Early identification of associated health risks of overconsumption of SSBs have important public health implications. Objective To investigate the differences in physical growth and glucolipid metabolism between different SSBs intake frequency groups in normal weight children and adolescents aged 6-17 years, and to evaluate the early effects of SSBs intake on physical growth and glycolipid metabolism before causing overweight and obesity, aiming to provide a scientific basis for the prevention and control of childhood overweight and obesity and related chronic diseases, and for the formulation of policies on the control of SSBs consumption. Methods Data were from the Shanghai Diet and Health Survey (SDHS) among primary and secondary school students. The participants were normal weight children and adolescents aged 6-17 years. Propensity scores were calculated according to energy intake and physical activity factors, after stratifying by age and gender. Participants were 1:1 matched with the closest propensity scores in the high-frequency (≥1 time·d⁻¹) and the low-frequency (≤1 time·week⁻¹) SSBs intake groups. The outcome indicators were physical measurements such as height, weight, percent of body fat, and waist circumference, and metabolic indicators such as fasting blood glucose, total triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Body mass index (BMI) was calculated. Food frequency questionnaire was used to collect SSBs consumption in the past three months through face-to-face interview. A paired t-test was used to compare the differences in physical and glycolipid metabolic indicators between the high-frequency intake group and the low-frequency intake group of SSBs. Results A total of 431 pairs were obtained. For children and adolescents in grades 6-9, overall height (difference=2.92 cm, P=0.002), weight (difference=2.53 kg, P=0.003), and waist circumference (difference=1.34 cm, P=0.035) were higher in those who consumed SSBs ≥1 time·d⁻¹ than in those who consumed ≤1 time·week⁻¹. For children and adolescents in grades 10-12, overall weight (difference=2.27 kg, P=0.041) was higher in those who consumed SSBs ≥1 time·d⁻¹ than in those who consumed ≤1 time·week⁻¹. Over 95% of the study subjects reported blood glucose and lipid test results within the normal range; but girls in grades 1-5 who consumed SSBs ≥1 time·d⁻¹ had a higher total cholesterol (difference=0.20 mmol·L⁻¹, P=0.027) and low-density lipoprotein cholesterol (difference=0.19 mmol·L⁻¹, P=0.010) than those who consumed ≤1 time·week⁻¹; boys in grades 6-9 who consumed SSBs ≥1 time·d⁻¹ had a lower high-density lipoprotein cholesterol (difference=-0.10 mmol·L⁻¹, P=0.039) than those who consumed ≤1 time·week⁻¹. Conclusion High-frequency intake of SSBs may be associated with higher total cholesterol and low-density lipoprotein cholesterol in normal weight children and adolescents in grades 1-5, and higher weight in normal weight children and adolescents in grades 6-12. There is an urgent need to educate children and adolescents about nutritional health, enhance their ability to make healthy food and beverage choices, and take early interventions to control the intake of SSBs in children.

Objective:To assess the concordance between different anthropometric indexes in the Global Leaders Initiated Malnutrition Standards(GLIM)and the Geriatric Risk Index(GNRI)for assessing muscle mass,and to explore performance-based criteria for GLIM muscle content appropriate for elderly patients with intermediate and advanced tumors.Methods:312 patients admitted to Shanghai Tenth People's Hospital from September 2022 to June 2023 were included.All patients were assessed nutritionally using the GLIM,applying the three methods of grip strength,upper arm circumference,and calf circumference as expressive criteria for assessing muscle content,and the diagnostic value of the three tools corresponding to the GLIM criteria was assessed using the GNRI as a reference standard.Results:Among 312 elderly patients with intermediate to advanced tumors,127(40.71％)and 138(44.23％),128(41.03％)and 162(51.92％)were diagnosed as malnourished based on the GNRI and GLIM---grip strength,GLIM---calf circumference,and GLIM---upper arm circumference in nutritional assessment,respectively.The GNRI and GLIM--Grip strength were both associated with incidence of complications and length of hospital stays.Using GNRI as a reference standard,GLIM-grip strength diagnosed malnutrition with good consistency(K value=0.692,P＜0.001),followed by calf circumference(K value=0.688,P＜0.001);compared with the other two indexes,the AUC of GLIM-grip strength was 0.851,with the correctness was 84.3％,with the best diagnostic value.Conclusion:Grip strength can be used as a practical and convenient muscle content performance-based criterion in the GLIM standards and is expected to be promoted in the diagnosis of malnutrition in elderly patients with intermediate and advanced malignancies.
