Objective To evaluate the molluscicidal effect and cost of spraying molluscicides with drones against Oncomelania hupensis snails in marshland and lake areas, so as to provide new insights into field snail control in China. Methods A marshland and lake setting measuring approximately 12 000 m² was selected in Wanzhi District, Wuhu City on June 2023 as the test field, and assigned to four groups, of 3 000 m² in each group. Environmental cleaning was not conducted in groups A or B, which were given 5% niclosamide ethanolamine salt granules sprayed with knapsack-type sprayers and drones at a dose of 40 g/m², and environmental cleaning was conducted in groups C and D, which were given 5% niclosamide ethanolamine salt granules sprayed with drones and knapsack-type sprayers at a dose of 40 g/m², respectively. O. hupensis snails were surveyed before chemical treatment and 1, 3, 5, 7, 14 days post-treatment. The uniformity of chemicals was determined on the day of treatment, and the snail mortality, corrected snail mortality and density of living snails were calculated and compared among groups. The cost of molluscicides, labor fees of environmental cleaning and chemical treatment and cost of equipment were calculated, and the cost for a 1% reduction in the mean density of living snails was calculated 14 days post-treatment. Results The mean densities of living snails and mortality rates of snails were 1.82 to 2.85 snails/0.1 m² and 1.41% to 2.94% in groups A, B, C and D before chemical treatment, and the mortality and corrected mortality of snails were 55.75%, 49.32%, 85.94% and 87.50%, and 55.00%, 48.47%, 85.70% and 87.29% in groups A, B, C and D 14 days post-treatment. There was a significant difference in the mortality of snails among the four groups 14 days post-treatment (χ² = 38.735, P < 0.005), and there was a higher snail mortality in Group D than in Group A (χ² = 16.876, P < 0.005), and higher in Group C than in Group B (χ² = 20.508, P < 0.005). The density of living snails reduced by 55.00%, 43.94%, 90.43% and 87.14% 14 days post-treatment relative to pre-treatment in groups A, B, C and D, respectively. The test for uniformity of chemicals showed that the mean dose of molluscicides were 57.34, 55.21, 40.19 g/m² and 32.37 g/m² in groups A, B, C and D, respectively, and the minimal standard deviation (7.07) and coefficient of variation (0.18) of mean doses were seen in Group C. The costs for chemical treatment were 0.33 Yuan in groups A and B and 1.53 Yuan in groups C and D, respectively. The costs for a 1% reduction in the mean density of living snails were 17.82, 22.47, 50.73 Yuan and 52.56 Yuan in groups A, B, C, and D 14 days post-treatment, respectively. Conclusions The molluscicidal effect and cost of spraying 5% niclosamide ethanolamine salt granules with drones are comparable to manual spraying, and chemical treatment with drones are high in uniformity of molluscicides, time- and labor-saving, and feasible for applications in complex environments, which deserves widespread applications in the field of snail control.

Objective To investigate the distribution and antimicrobial resistance of clinical isolates in the First Affiliated Hospital of Xi'an Jiaotong University in 2022 for rational use of antibiotics in clinical practice.Methods Nonduplicate clinical isolates were collected from January 1,2022 to December 31,2022.Antimicrobial susceptibility testing was carried out using Kirby-Bauer method and automated systems.The data were analyzed using WHONET 5.6 software and interpreted according to the Clinical and Laboratory Standards Institute(CLSI)breakpoints(2021 Edition).Results Of the 8 638 clinical isolates,gram negative bacteria and gram positive bacteria accounted for 60.8％(5 253/8 638)and 39.2％(3 385/8 638),respectively.The prevalence of methicillin-resistant strains was 33.0％in S.aureus(MRSA),75.8％in S.epidermidis(MRSE),and 51.9％in other coagulase-negative Staphylococcus(MRCNS).No staphylococcal strains were found resistant to vancomycin.The prevalence of vancomycin-resistant E.faecium was 0.6％,and no vancomycin-resistant E.faecalis was found.E.faecalis strains showed higher resistance rate to linezolid(5.2％)than E.faecium(0.7％).The prevalence of carbapenem-resistant Enterobacterales(CRE)was 7.9％,specifically 12.1％for carbapenem-resistant K.pneumoniae(CRKP)and 1.6％for carbapenem-resistant E.coli(CREC).The prevalence of carbapenem-resistant P.aeruginosa(CRPA)and carbapenem-resistant A.baumannii(CRAB)was 30.9％and 77.0％,respectively.Conclusions Clinical microbiology laboratories should strengthen the collection and testing of clinical specimens from the sites of infection in order to improve pathogenic diagnosis and antimicrobial resistance surveillance.This is conducive to the rational use of antibiotics and reduce the further spread of multidrug-resistant bacteria.

Objective:To analyze the clinical phenotype and genetic characteristics of a patient with Isidor-Toutain spinal epiphyseal dysplasia (SEMD) due to variant of RPL13 gene. Methods:A pregnant woman at 18 weeks of gestation who had presented at Quzhou Maternal and Child Health Care Hospital on January 14, 2023 was selected as the study subject. Whole exome sequencing (WES) was carried out for the patient, and candidate variant was validated by Sanger sequencing and bioinformatic analysis.Results:The woman was 37 years old with extremely short stature (135 cm) and "O" shaped legs. WES revealed that she has harbored a c. 548G>C (p.Arg183Pro) missense variant of the RPL13 gene (NM_000977.4). The same variant was not found in her fetus. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be likely pathogenic (PS4+ PM2_Supporting+ PP3+ PP4). Conclusion:Isidor-Toutain type SEMD due to variants of the RPL13 gene may have variable expressivity and diverse clinical phenotypes. Above finding has facilitated the differential diagnosis and genetic counseling for this family.

Objective:To analyze the influence of lifestyle changes on body weight and metabolic parameters during the early stage of corona virus disease 2019 (COVID-19) epidemic and regular epidemic prevention period in physical examination population.Methods:A total of 801 subjects from Nanjing enterprises and institutions who underwent physical examination in the Department of Health Promotion Center, the First Affiliated Hospital of Nanjing Medical University in May of 2019 to 2021 were included in this study. The basic information and data of body mass index, fasting blood glucose, total cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride and uric acid were collected. Information about dietary and exercise habits was obtained through pre-examination questionnaires. The data of 2019 was set as baseline data, data of 2020 represented information during the early stage of COVID-19 epidemic and data of 2021 represented information in regular epidemic prevention period. The subjects were divided into underweight group, normal weight group, overweight group, and obese group according to the body mass index at baseline. The Friedman test was applied to compare changes in body mass index and metabolic parameters across the population. Chi-square test was used to compare changes in dietary and exercise habits. Multivariate logistic regression analysis was adopted to explore the influencing factors of body mass index changes.Results:During the early stage of COVID-19 epidemic, the proportion of weight gain was the highest in the underweight group (42.9%), the proportion of weight loss was the highest in the overweight group (24.2%), and the obese group has the most stable body weight (70.6%) ( P=0.004). Men ( OR=0.56, 95% CI: 0.36-0.87) were less likely to gain weight than women ( P=0.010). There was no significant differences in weight change among all groups in the regular epidemic prevention period ( P=0.380). During the early stage of COVID-19 epidemic, the levels of fasting blood glucose, total cholesterol and LDL-C were significantly lower than those of baseline [4.98 (4.66, 5.42) vs 5.23 (4.91, 5.66) mmol/L, 4.98 (4.36, 5.67) vs 5.11 (4.54, 5.77) mmol/L, 2.90 (2.45, 3.33) vs 3.23 (2.77, 3.74) mmol/L], and the uric acid level was higher [333.0 (275.5, 397.0) vs 311.0 (257.5, 368.0) μmol/L] (all P<0.001). In regular epidemic prevention period, the levels of body mass index, fasting blood glucose, total cholesterol and LDL-C were significantly higher than those in the early stage of the epidemic [24.0 (21.9, 26.3) vs 23.8 (21.7, 26.1) kg/m 2, 5.18 (4.85, 5.62) vs 4.98 (4.66, 5.42) mmol/L, 5.12 (4.42, 5.76) vs 4.98 (4.36, 5.67) mmol/L, 3.06 (2.59, 3.57) vs 2.90 (2.45, 3.33) mmol/L], while the uric acid was significantly lower [319.0 (265.0, 377.0) vs 333.0 (275.5, 397.0) μmol/L] (all P<0.001). During the early stage of the epidemic, the reduction proportion of unhealthy diet in the home group was significantly higher than that in the outing group (19.5% vs 11.4%), and the increment proportion of exercise in the outing group was significantly higher than that in the home group (5.1% vs 1.6%) (both P<0.05). In regular epidemic prevention period, the increase rate of unhealthy diet in the home group was significantly higher than that in the outing group (26.8% vs 13.0%) ( P<0.001), and there was no significant difference in exercise between the two groups ( P=0.325). During the early stage of COVID-19 epidemic and in the regular epidemic prevention period, unhealthy diet>3 times per week ( OR=3.85, 3.01, 95% CI: 1.74-8.51, 1.41-6.39) was positively correlated with weight gain, and regular exercise ( OR=4.35, 2.61, 95% CI: 2.05-9.23, 1.15-5.91) was positively correlated with weight loss (all P<0.05). Conclusions:During the early stage of COVID-19 epidemic and in the regular epidemic prevention period, the lifestyle in the physical examination population has an impact on body weight and metabolic indicators. In the early stage of the epidemic, unhealthy diet and exercise decreased, and metabolic indicators such as blood glucose and lipids decreased. People with low body weight tend to gain weight. In the regular epidemic prevention period, the subjects′ exercise increased but unhealthy diet also increased, and blood glucose, lipid and body weight elevated significantly.

Objective:To translate the Efficacy of Self-Efficacy for Managing Symptoms (SEMSX) based on the Patient-Reported Outcomes Measurement Information System (PROMIS) into Chinese, and to test the reliability and validity of the scale among Chinese patients with nasopharyngeal carcinoma.Methods:The English version of PROMIS-SEMSX was translated into Chinese according to the FACIT translation method. The reliability and validity of the scale were evaluated. From January to April in 2021, the convenient sampling method was adopted to select 205 patients with nasopharyngeal cancer in Zhejiang Cancer Hospital for investigation.Results:The Chinese version of PROMIS-SEMSX scale consisted of 28 items in 4 dimensions, which were consistent with confidence level(with 7 items), symptom management(with 5 items), the impact of symptoms on life(9 items), seeking and understanding support(7 items). The calibration correlation validity was 0.935. The total Cronbach α coefficient of the scale was 0.966, and the half-reliability of the total scale was 0.891. The Cronbach α coefficient of each dimension was 0.910-0.938, and the total retest reliability coefficient of the scale was 0.757.Conclusions:The Chinese version of PROMIS-SEMSX has good reliability and validity in patients with nasopharyngeal carcinoma, and provides a new tool for patients with nasopharyngeal carcinoma to evaluating self-efficacy symptom management.

Objective:To explore the status quo of symptom management self-efficacy based on patient reported outcomes of nasopharyngeal carcinoma patients and analyze its related factors.Methods:From January to April 2021, 230 patients with nasopharyngeal carcinoma who were treated in Zhejiang Cancer Hospital were selected as the study subject by convenient sampling. The General Information Questionnaire and Patient-Reported Outcome Measurement Information System-Self-Efficacy for Managing Symptoms (PROMIS-SEMSX) were used to investigate. Single factor analysis and multiple linear regression analysis were used to explore the influencing factors of symptom management self-efficacy in patients with nasopharyngeal carcinoma.Results:A total of 230 questionnaires were distributed, 220 were recovered, and 205 were valid. The score of symptom management self-efficacy of patients with nasopharyngeal carcinoma was (97.74±20.00) , which was above the middle level, and the lowest score dimension was confidence, which was (23.52±5.91) . Multiple linear regression showed that gender, education level, medical expense payment method, economic level, tumor stage, course of disease, tumor recurrence and metastasis were the influencing factors of symptom management self-efficacy of nasopharyngeal carcinoma patients ( P<0.05) . A total of 41.5% of the total variation was explained. Conclusions:The self-efficacy of symptom management in patients with nasopharyngeal carcinoma needs to be improved. The medical and nursing staff should focus on the patients with low educational level, heavy economic burden, late tumor, recurrence and metastasis, and focus on providing specific health guidance to alleviate their discomfort symptoms during treatment, and improve their self-efficacy of symptom management.

Extensive intracranial calcification is rare in patients with systemic lupus erythematosus. This article reported a patient with antiphospholipid antibody syndrome secondary to systemic lupus erythematosus, complicated with bilateral symmetrical extensive intracranial calcification. By reviewing literature, the results suggested that the flare of neuropsychiatric systemic lupus erythematosus and the presence of antiphospholipid antibodies may be risk factors for intracranial calcification. Therefore, in order to prevent the formation of intracranial calcification, it is necessary to maintain continuous disease remission and anticoagulant therapy.

Objective To investigate the nutrient contents of various grains in Hubei Province, and to provide a scientific basis for a balanced diet. Methods Various grains (except potatoes and beans) on the market in Hubei Province were collected. The samples were prepared by peeling and milling, or directly milling, and the nutrient contents were determined according to the national standard methods. With reference to the American nutrient profiling model, protein, dietary fiber, vitamin C, vitamin A, vitamin E, potassium, magnesium, iron and calcium, the nine nutrients were selected as recommended nutrients, and sodium, added sugars and fat were restricted nutrients. On the basis of 100 g for calculation, a nutrient-rich food model (Nutrient-rich foods, NRF_9.3) was established and applied to evaluate the grains. Results The evaluation results showed that wheat and buckwheat grains contained a higher recommended nutrient content than restricted nutrient content, and had higher nutritional value. Among them, quinoa (black) had the highest NRF index of 102.4, indicating the most nutritional value. After peeling, the loss rate of nutrient value (NRF_9.3 index) of various grains was 38.73% to 65.00%. Conclusion It is recommended that people should try to choose whole grains when purchasing grain products.

Objective: To explore whether extracellular histones aggravate acute respiratory distress syndrome (ARDS) by inducing peripheral blood mononuclear cell (PBMC) pyroptosis. Methods: Twenty patients with ARDS admitted to Shanghai Pulmonary Hospital, Tongji University School of Medicine from April to September in 2019 were enrolled, and 20 healthy volunteers were enrolled as controls. In vivo experiment: peripheral blood samples of patients with ARDS within 24 hours after diagnosis and healthy volunteers were collected, and the levels of plasma extracellular histone, interleukins (IL-1β and IL-18) and lactic dehydrogenase (LDH) were determined by enzyme-linked immunosorbent assay (ELISA). PBMC were harvested, the expression levels of the pyroptosis associated N terminal-gasdermin-D (GSDMD-N) protein were determined by Western Blot. In vitro experiment: PBMC isolated from healthy volunteers were divided into four groups. Blank control group without any treatment; lipopolysaccharide (LPS) group was treated with 1 mg/L LPS for 4 hours; LPS+histones group was treated with 100 mg/L exogenous histones for 24 hours after LPS treatment; LPS+histone+heparin group was treated with 200 U heparin for 24 hours after LPS and exogenous histones treatment. The GSDMD-N protein expression was determined by Western Blot, and the levels of IL-1β, IL-18 and LDH in cell supernatant were determined by ELISA. Spearman test was used to test the correlation among the parameters. Results: In vivo experiment results: compared with healthy control group, the GSDMD-N protein expression in PBMC of patients with ARDS was significantly increased [GSDMD-N/GAPDH: 0.136 (0.062, 0.246) vs. 0.026 (0.018, 0.036), P < 0.01], as well as the plasma levels of IL-1β, IL-18, LDH and extracellular histones [IL-1β (ng/L): 120.0 (94.2, 213.0) vs. 88.5 (82.3, 105.3), IL-18 (ng/L): 164.5 (70.8, 236.3) vs. 60.5 (52.0, 89.0), LDH (U/L): 30.9 (24.7, 39.5) vs. 19.8 (17.2, 21.5), extracellular histones (mg/L): 73.0 (42.8, 112.9) vs. 12.2 (9.6, 16.9), all P < 0.01], indicating that the PBMC of ARDS patients had significant pyroptosis and release of a large number of inflammatory factors. The oxygenation index (PaO₂/FiO₂) of ARDS patients was 135.5 (94.5, 196.0) mmHg (1 mmHg = 0.133 kPa). Correlation analysis showed that the expression of GSDMD-N protein in patients with ARDS was negatively correlated with PaO₂/FiO₂ (r = -0.935, P < 0.01) and positively correlated with IL-1β, IL-18, LDH and extracellular histones (r value was 0.844, 0.843, 0.887, 0.899, respectively, all P < 0.01). In vitro experiment results: compared with blank control group, the expression of GSDMD-N protein in PBMC and the levels of inflammatory mediators in the supernatant of the LPS group were significantly increased [GSDMD-N/GAPDH: 0.035±0.006 vs. 0.028±0.006, IL-1β (ng/L): 39.8±5.5 vs. 22.6±4.7, IL-18 (ng/L): 31.2±4.4 vs. 20.0±2.2, LDH (U/L): 51.2±7.3 vs. 36.6±7.6, all P < 0.05], indicating that LPS stimulation could increase PBMC pyroptosis and the release of inflammatory mediators. Compared with LPS group, the expression of GSDMD-N protein and the levels of inflammatory mediators of the LPS+histones group were further increased [GSDMD-N/GAPDH: 0.114±0.009 vs. 0.035±0.006, IL-1β (ng/L): 119.0±18.7 vs. 39.8±5.5, IL-18 (ng/L): 49.2±8.5 vs. 31.2±4.4, LDH (U/L): 127.8±19.8 vs. 51.2±7.3, all P < 0.01], indicating that the stimulation of LPS on PBMC could be significantly amplified by exogenous histone treatment, GSDMD-N protein expression could be up-regulated and inflammatory factor release could be promoted to further induce PBMC pyroptosis. These adverse effects of exogenous histones on PBMC could be abrogated by heparin, the expression of GSDMD-N protein and the levels of inflammatory mediators were significantly lower than those of LPS+histones group [GSDMD-N/GAPDH: 0.063±0.004 vs. 0.114±0.009, IL-1β (ng/L): 46.8±8.6 vs. 119.0±18.7, IL-18 (ng/L): 33.0±5.1 vs. 49.2±8.5, LDH (U/L): 65.4±11.0 vs. 127.8±19.8, all P < 0.05]. Conclusion Extracellular histones in plasma may aggravate ARDS by mediating PBMC pyroptosis.
