Objective:To apply the best evidence for nutritional management in patients with chronic heart failure (CHF) into clinical practice and evaluate its effectiveness.Methods:Totally 80 CHF patients admitted to the Department of Cardiology at the Affiliated Hospital of Chengde Medical University from October 2022 to March 2023 and 23 nurses involved in the project were selected by convenience sampling. The 40 CHF patients admitted from October to December 2022 formed the baseline group, while those admitted from January to March 2023 constituted the evidence application group. Evidence-based nursing methods were implemented in four stages: evidence retrieval, current status review, evidence implementation, and effectiveness evaluation. The compliance rates of review indicators, nurses' knowledge of nutritional management for CHF patients, and patient outcomes related to nutrition status and readmission rates were compared before and after evidence-based practice.Results:After evidence-based practice, the compliance rates of review indicators increased from 0-60.87% to 80.00%-100.00%. Nurses' scores on nutritional management knowledge for CHF patients increased significantly from (48.48±13.09) to (91.30±4.82), with a statistically significant difference ( P<0.05). The NRS 2002 scores of CHF patients decreased from (3.05±0.50) to (2.10±0.44), MNA-HF scores increased from (18.20±2.64) to (21.24±2.94), and albumin levels increased from (37.33±4.98) g/L to (39.24±3.29) g/L, all with statistically significant differences ( P<0.05). The 3-month readmission rate for CHF patients in the evidence application group was 10.00% (4/40), significantly lower than the 27.50% (11/40) in the baseline group ( P<0.05) . Conclusions:Evidence-based nursing practice for nutritional management in CHF patients can enhance nurses' knowledge, improve patients' nutritional status, reduce readmission rates, and improve the quality of nursing care.

Objective:To explore the real experience and needs of lymphoma patients during chimeric antigen receptor T cell (CAR-T) therapy, so as to provide guidance for developing nursing intervention strategies.Methods:The phenomenological research method was used to conduct semi-structured interviews with 13 lymphoma patients receiving CAR-T therapy, and the interview data was analyzed using the Colaizzi 7-step analysis method.Results:Three themes were extracted, including diverse symptom perception (systemic symptoms such as fever and fatigue, as well as multiple system symptoms such as breathing, digestion, and nerves), complex emotional experience interweaving (coexistence of hope and doubt, changes and loss of environmental adaptability, and a variety of negative emotions), and urgent social needs (treatment related information needs, desire for medical and nursing staff's attention and help, family emotional support, and home rehabilitation continuing care) .Conclusions:Lymphoma patients experience significant physical and mental pain during CAR-T therapy. Medical and nursing staff should provide patients with comprehensive support to help them identify and improve physical discomfort symptoms, reduce psychological burden, meet physical and mental needs, and promote disease recovery.

Objective To analyze coating properties of porous artificial joints,including coating morphology and coating mechanical properties,and summarize the range of coating properties of current mainstream products,to provide references for the design and development of new products,as well as provide the basis for the long-term implant removal analysis.Methods Samples for the surface morphology,shear strength,and tensile strength of the coatings used in the experiment were prepared in accordance with ASTM F1854,ASTM F1044,and ASTM F1 147 standards,respectively.The coatings were processed using plasma spraying.The surface morphology(coating thickness,porosity,and pore intercept)of the coatings for all 17 products(Nos.1-17)was tested;for products Nos.1-7 and Nos.15-16,the shear strength test between the coating and substrate was conducted first in accordance with the test method of ASTM F1044.Then,according to the test method of ASTM F1 147,the tensile strength test between the coating and substrate was conducted.For product No.17,the shear and tensile strengths of the composite coating and simple titanium coating were tested,respectively,according to the test method of ASTM F1044 and ASTM F1 147.Results A total of 15 products(88.2％)had coating thicknesses between 300 μm and 500 μm.There were 16 metal-coated products(Nos.1-16),of which 11(68.75％of the total)had coating porosities between 30％and 50％,and 14(87.5％of the total)had coating pore intercepts between 50 μm and 150 μm.The mechanical properties of the coatings were independent of the substrate material used.The shear and tensile strengths of the composite coatings with hydroxyaptite(HA)were significantly lower than those of the pure metal coatings.Conclusions For the design and manufacture of artificial joints with porous coatings,the performance of the coating can be referred to the following indexes:the coating thickness is 300-500 μm,the coating porosity is 30％-50％,the coating pore intercept is 50-150 μm.The substrate materials can be selected based on the use of the product.The effects of a lower bonding force on product performance should be considered when designing prostheses with composite coatings containing HA.This range of performance metrics provides control for long-term clinical extraction analyses.

Objective To investigate the prevalence and molecular characteristics of Anaplasma infections in sheep and goats in Anhui Province in 2020, so as to provide insights into ovine anaplasmosis prevention and control. Methods A total of 355 fresh blood samples were collected from 7 sheep and goat farms in Linquan County of Fuyang City, Lixin County of Bozhou City, Yu'an District of Lu'an City, Wangjiang County of Anqing City, Nanling County of Wuhu City, and Tianchang City and Fengyang County of Chuzhou City in Anhui Province from June to December 2020. A. bovis and A. phagocytophilum 16S ribosomal RNA (16S rRNA) gene, A. ovis major surface protein 4 (MSP4) gene and A. capra citric acid synthase (gltA) gene were amplified using PCR assay in all blood samples, and the prevalence of A. bovis, A. phagocytophilum, A. ovis and A. capra infections was calculated in sheep and goats. In addition, the positive amplification products were sequenced and subjected to genetic evolutionary analysis. Results The overall prevalence of Anaplasma infections was 17.5% (62/355) in sheep and goats in Anhui Province, and the prevalence of A. bovis, A. phagocytophilum, A. ovis and A. capra infections was 2.8% (10/355), 2.5% (9/355), 2.5% (9/355), and 7.0% (25/355), while the prevalence of A. bovis and A. phagocytophilum, A. phagocytophilum and A. ovis, A. phagocytophilum and A. capra and A. bovis, A. phagocytophilum and A. ovis co-infections was 0.8% (3/355), 1.1% (4/355), 0.3% (1/355) and 0.3% (1/355), respectively. No Anaplasma was detected in the sheep and goat farms in Fengyang County, while at least three Anaplasma species were detected in other sheep and goat farms, with co-infections of multiple Anaplasma species identified. The prevalence of Anaplasma infections was 14.7% (24/163) in goats and 19.8% (38/192) in sheep, and the prevalence of Anaplasma infections was 31.0% (31/100) in goats and sheep under 6 months of age, and 12.2% (31/255) in goats and sheep at ages of 6 months and older, respectively. A. bovis, A. phagocytophilum, A. ovis and A. capra were identified in sheep and goats of different breeds and ages. Conclusions Multiple Anaplasma species infections were commonly prevalent in goats and sheep in Anhui Province in 2020, notably A. phagocytophilum, A. ovis and A. capra, which have zoonotic risks. Improved surveillance and prevention and control of Anaplasma infections are required in sheep and goats in Anhui Province.

Objective The leptin receptor,encoded by the LEPR gene,is involved in tumorigenesis.A potential functional variant of LEPR,rs1137101(Gln223Arg),has been extensively investigated for its contribution to the risk of digestive system(DS)cancers,but results remain conflicting rather than conclusive.Here,we performed a case-control study and subsequent meta-analysis to examine the association between rs1137101 and DS cancer risk. Methods A total of 1,727 patients with cancer(gastric/liver/colorectal:460/480/787)and 800 healthy controls were recruited.Genotyping of rs1137101 was conducted using a polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)assay and confirmed using Sanger sequencing.Twenty-four eligible studies were included in the meta-analysis. Results After Bonferroni correction,the case-control study revealed that rs1137101 was significantly associated with the risk of liver cancer in the Hubei Chinese population.The meta-analysis suggested that rs1137101 is significantly associated with the risk of overall DS,gastric,and liver cancer in the Chinese population. Conclusion The LEPR rs1137101 variant may be a genetic biomarker for susceptibility to DS cancers(especially liver and gastric cancer)in the Chinese population.

Oral squamous cell carcinoma(OSCC)is the predominant type of oral cancer,while some patients may develop oral multiple primary cancers(MPCs)with unclear etiology.This study aimed to investigate the clinicopathological characteristics and genomic alterations of oral MPCs.Clinicopathological data from patients with oral single primary carcinoma(SPC,n=202)and oral MPCs(n=34)were collected and compared.Copy number alteration(CNA)analysis was conducted to identify chromosomal-instability differences among oral MPCs,recurrent OSCC cases,and OSCC patients with lymph node metastasis.Whole-exome sequencing was employed to identify potential unique gene mutations in oral MPCs patients.Additionally,CNA and phylogenetic tree analyses were used to gain preliminary insights into the molecular characteristics of different primary tumors within individual patients.Our findings revealed that,in contrast to oral SPC,females predominated the oral MPCs(70.59%),while smoking and alcohol use were not frequent in MPCs.Moreover,long-term survival outcomes were poorer in oral MPCs.From a CNA perspective,no significant differences were observed between oral MPCs patients and those with recurrence and lymph node metastasis.In addition to commonly mutated genes such as CASP8,TP53 and MUC16,in oral MPCs we also detected relatively rare mutations,such as HS3ST6 and RFPL4A.Furthermore,this study also demonstrated that most MPCs patients exhibited similarities in certain genomic regions within individuals,and distinct differences of the similarity degree were observed between synchronous and metachronous oral MPCs.

Objective To investigate the prevalence and molecular features of Cryptosporidium in captive-bred Mustela putorius furo in Jiangsu Province.. Methods A total of 290 fresh stool samples were collected from a ferret farm in Jiangsu Province on May 2017, and the small subunit rRNA (SSU rRNA) gene of Cryptosporidium was amplified in stool samples using nested PCR assay. The actin, cowp and gp60 genes were amplified in positive samples and sequenced to characterize Cryptosporidium species/genotypes. Results A total of 18 stool samples were tested positive for Cryptosporidium SSU rRNA gene, with a detection rate of 6.2%. Sequence and phylogenetic analyses of SSU rRNA, actin and cowp genes characterized Cryptosporidium isolated from captive-bred ferrets as Cryptosporidium sp. ferret genotype. In addition, gp60 gene was amplified in 10 out of 18 stool samples tested positive for Cryptosporidium. Conclusions Cryptosporidium is widely prevalent in captive-bred ferrets in Jiangsu Province, and Cryptosporidium sp. ferret genotype is the only Cryptosporidium genotype in ferrets.

Objective To evaluate the application and effect of signature verification technology in children's vaccination clinics (CVC) of Jiangsu Province in 2020. Methods The signature verification data were derived from the Jiangsu Provincial Vaccination Integrated Service Management Information System, and the inquiry and registration, informed consent, vaccine traceability code scanning and observation information of children's vaccination clinics in different regions were analyzed. 210 doses of vaccination information were randomly selected from CVCs in each county, and the length of vaccination services in different regions was compared. Results During 2020, all of CVCs in Jiangsu were equipped with signature verification technology, and the signature verification rate of each vaccination sector was more than 99.90%. The length of outpatient vaccination service and overall length of stay in southern Jiangsu were slightly shorter than those in other regions. Conclusion The introduction of electronic signature verification technology in CVCs can effectively standardize the vaccination. It is necessary to expand the functions of electronic signature verification equipment, strengthen data analysis and utilization, and guide vaccination scientifically.

OBJECTIVE: To investigate the prevalence and subtype distribution of Blastocystis sp. in pigs in Anhui Province. METHODS: A total of 500 stool samples were collected from large-scale pig farms in Bozhou, Anqing, Chuzhou, Hefei, Fuyang, and Lu'an cities in Anhui Province from October to December 2015. Blastocystis was detected in pig stool samples using a PCR assay based on the small subunit ribosomal RNA (SSU rRNA) gene, and positive samples were subjected to sequencing and sequence analysis. Blastocystis subtypes were characterized in the online PubMLST database, and verified using phylogenetic tree created with the neighbor-joining algorithm in the Meta software. RESULTS: The prevalence of Blastocystis infection was 43.2% (216/500) in pigs in 6 cities of Anhui Province, and all pig farms were tested positive for Blastocystis. There was a region-specific prevalence rate of Blastocystis (17.2% to 50.0%) (χ² = 26.084, P < 0.01), and there was a significant difference in the prevalence of Blastocystis sp. among nursery pigs (39.6%), preweaned pigs (19.1%), and growing pigs (62.3%) (χ² = 74.951, P < 0.01). Both online inquiry and phylogenetic analysis revealed ST1, ST3, and ST5 subtypes in pigs, with ST5 as the predominant subtype. CONCLUSIONS The prevalence of Blastocystis sp. is high in pigs in Anhui Province, with three zoonotic subtypes identified, including ST1, ST3, and ST5.
