A virus was successfully isolated from a sick cat exhibiting clinical signs such as oral mu-cosal ulceration,nasal mucosal redness,and increased nasal secretions utilizing F81 cells.Through a comprehensive analysis as such PCR amplication,sequencing,morphology,serology,and animal re-gression tests,the virus was identified as a feline calicivirus and named FCV-BJ,an inactivated vac-cine was developed from this isolated strain its safety and efficacy were assessed.The results re-vealed that the isolated FCV-BJ strain exhibited characteristic serological and morphological fea-tures consistent with caliciviruses.Furthermore,inoculation of cats with the FCV-BJ demonstrated the strain is highly virulent and the cats manifested the clinical signs of feline calicivirus infection.For the vaccination trial,domestic cats were immunized with inactivated fifth-generation virus cell culture at varying dilutions,followed by a booster immunization after 21 days.Fourteen days after the challenge with the virus,cats immunized with 107.0 TCID50/mL or higher remained largely healthy,while all cats in the control group developed clinical signs of FCV.These findings suggest that the inactivated vaccine derived from the FCV-BJ isolate exhibits strong immunogenicity and protective efficacy at a minimum immunization dose of 107.0 TCID50/mL.This strain holds promise as a candidate for vaccine production,providing a valuable reference and foundation for future re-search and development of feline calicivirus vaccines.

Objective To explore the application effect of upper abdominal moxibustion combined with bedside ultrasound monitoring of gastric residual volume(GRV)in pre-pyloric feeding in stroke patients.Methods Eighty stroke patients admitted to the Department of Rehabilitation Medicine of Zhejiang Provincial People's Hospital from January 1,to December 31,2023 were selected as the study subjects.They were divided into control group(n=38)and observation group(n=42)using a random number table method.All patients had a nasogastric tube for pre-pyloric feeding.The control group used the traditional syringe aspiration method to monitor GRV,while the observation group used upper abdominal moxibustion combined with bedside ultrasound to monitor GRV.The study compared the differences between two groups in terms of enteral nutrition intolerance,feeding complications,enteral nutrition compliance rate within 7 days of admission,time to achieve enteral nutrition compliance,and changes in hemoglobin(Hb),serum prealbumin,serum albumin(ALB),and serum transferrin before and after 14 days of feeding.Results The incidence rates of vomiting,abdominal distention,intra-abdominal hypertension,reflux,and aspiration pneumonia in observation group were lower than those in control group(P＜0.05).The rate of achieving intestinal nutrition standard within 7 days of hospitalization was significantly higher in observation group compared to the control group.The time to achieve intestinal nutrition standard was shorter in observation group compared to control group.Furthermore,after 14 days of feeding,the levels of Hb and ALB in observation group were higher than those in control group,and the differences were statistically significant(P＜0.05).Conclusion Upper abdominal moxibustion combined with bedside ultrasonic monitoring of GRV can significantly reduce intestinal nutrition intolerance and feeding complications during pre-pyloric feeding in stroke patients,shorten the time to achieve nutritional benchmarks,and improve nutritional status.

Objective:To conduct a scoping review to analyse the types, performance, advantages and disadvantages of cognitive function assessment tools for ICU patients, to provide a reference for the evaluation of cognitive function in ICU patients in future.Methods:A scoping review study was conducted, literature on cognitive function assessment tools for ICU patients in 9 domestic and foreign databases including China National Knowledge Infrastructure, Wanfang Database, VIP Database, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, Embase and CINAHL were systematically searched. The search period was from the establishment of the database to May 20, 2024. Literature was independently screened by 2 researchers and relevant information was extracted and summarized.Results:Totally 17 studies were included, with 9 tools for assessing cognitive function in ICU patients, including 6 questionnaires, 1 test battery, 1 assessment software, and 1 telephone interview questionnaire. All of above were generalizable tools, except for the Chinese and English versions of the John-Hopkins Adapted Cognitive Exam as ICU-specific tools. The Mini-Mental State Examination was the most widely used assessment scale.Conclusions:Appropriate assessment tools should be selected according to the specific clinical setting, but there is still a lack of specialized and standardized assessment tools for cognitive dysfunction in ICU patients. In the future, standardized tools which fit our cultural context for evaluating cognitive function in ICU patients should be developed.

Surgery is the main clinical treatment for papillary thyroid carcinoma(PTC),and with the advancement of medical technology,PTC surgical treatment has made significant progress.However,there is still controversy in the academic community re-garding the scope of PTC surgical resection and lymph node dissection.Moreover,as PTC shows a trend towards youthfulness,patients′demands for surgical methods,surgical timing,surgical outcomes,and postoperative aesthetics are gradually increasing.Therefore,the choice of PTC surgical method needs to consider more aspects besides lesion resection and disease relief.This article reviews the pro-gress and limitations of surgical treatment for PTC.

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.

ObjectiveTo investigate the attenuating effect of Dioscoreae Bulbiferae Rhizoma（DBR） processed with Phaseoli Radiati Semen（PRS） juice， and explore the attenuating mechanism based on ferroptosis of the main toxic target organ. MethodSixty male ICR mice were randomly divided into blank group， DBR group， water roasted DBR group（hereinafter referred to as water group）， PRS juice-roasted DBR group 1（DBR-PRS 10∶1， stuffy moistening for 40 min， stir-fried at 130 ℃ for 18 min， hereinafter referred to as group 1）， PRS juice-roasted DBR group 2（DBR-PRS 10∶1， stuffy moistening for 80 min， stir-fried at 100 ℃ for 14 min， hereinafter referred to as group 2）， PRS juice-roasted DBR group 3（DBR-PRS=20∶3， stuffy moistening for 40 min， stir-fried at 160 ℃ for 14 min， hereinafter referred to as group 3）. The raw and processed groups of DBR were gavaged with their corresponding 95% ethanol extract at a dose of 3 g·kg^-1·d^-1， while the blank group was gavaged with an equal volume of 0.5% sodium carboxymethyl cellulose， once a day for 14 consecutive days. Hematoxylin-eosin（HE） staining was used to observe the histopathological changes of mouse liver. Alanine aminotransferase（ALT） and aspartate aminotransferase（AST） levels in serum， as well as malondialdehyde（MDA）， ferrous ions（Fe²⁺）， reduced glutathione（GSH） and superoxide dismutase（SOD） levels in liver tissue were detected by the biochemical detection. Western blot was used to detect the expression of iron key proteins such as ferritin heavy chain 1（FTH1） and glutathione peroxidase 4（GPX4）. ResultHE staining results showed that the liver tissue structure of the blank group was clear， the morphology of hepatocytes was normal， the cytoplasms of hepatocytes in the DBR group and water group were loose and vacuolar， with obvious pathological damages， and the pathologic damages of mice in the group 1-3 were significantly improved. Compared with the blank group， the levels of ALT， AST， MDA and Fe²⁺ in mice from the DBR group were significantly increased（P<0.01）， while GSH and SOD levels were significantly reduced（P<0.01）， and the protein expression levels of FTH1 and GPX4 were significantly decreased（P<0.01）. Compared with the DBR group， the ALT， AST，MDA and Fe²⁺ levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the GSH and SOD levels and the protein expression levels of FTH1 and GPX4 were significantly increased（P<0.01）. Compared with the water group， the AST and MDA levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the SOD level significantly increased（P<0.05， P<0.01）， the FTH1 protein expression significantly increased（P<0.01）， and the serum ALT level of mice in the group 2-3 significantly reduce（P<0.01）， Fe²⁺ level significantly reduced（P<0.01）， GSH level significantly increased（P<0.05， P<0.01）， and GPX4 protein expression significantly increased（P<0.05， P<0.01）. Among the group 1-3， the group 3 had the best detoxification effect. ConclutionProcessing with PRS juice can reduce the liver injury induced by DBR， and the mechanism may be related to the inhibition of ferroptosis in the liver.

Objective:To confirm the potential etiological factors of congenital aortic stenosis(AS)by genetic analysis on prenatal diagnostic results of the fetus with AS.Methods:Amniocentesis for chromosomal G-band karyotyping combinated with single nucleotide polymorphism array(SNP-array)analysis was conducted on the amniotic fluid collected from a 25-week pregnant woman diagnosed as"fetus AS";chromosome karyotyping was also performed on the peripheral blood of the fetal parents.Results:The fetal karyotype analysis showed a chimeric Y-chromosome isobaric double-adherent granules.The SNP-array analysis results revealed a 11.2 Mb duplication in the Yp11.31q11.21 region and a 14.8 Mb deletion in the Yq11.21q11.23 region.Both the parents presented a normal karyotype,suggesting it was a newfound mutation.After extensive genetic counseling,the pregnant woman and her family chose to terminate the pregnancy locally.Conclusion:The chromosomal karyotype of the chimeric Y-chromosome isobaric double-adherent granules may be a contributing factor to the AS phenotype in the male fetus.The combined use of chromosomal karyotyping and SNP-array analysis on the amniotic cells is instrumental in the early diagnosis of the disease.

Objective To evalute the drug resistance characteristics of tuberculosis(TB)patients of all ages in Guangdong Province during 2014-2020,and provide prevention and treatment strategies of tuberculosis.Method We used 39,048 clinical isolates of Mycobacterium tuberculosis(MTB)belonging to patients with confirmed TB from 2014 to 2020,from 32 TB drug-resistant surveillance sites in Guangdong Province,and we retrospectively analyzed the laboratories data of patients with drug-resistant TB,and grouped patients by age and region,to explore the trend of drug-resistance of MTB clinical isolates,the trend and incidence differences of multi-resistant TB(including monodrug-resistant TB(MR-TB),polydrug-resistant TB(PDR-TB),multidrug-resistant TB(MDR-TB)and exten-sively drug-resistant TB(XDR-TB)),and resistance characteristics of MTB clinical isolates to drugs in focus(rifam-picin and ofloxacin).Result The differences in the resistance rates of MTB clinical isolates to nine antituberculosis drugs among patients at 32 TB drug resistance surveillance sites in Guangdong Province from 2014 to 2020 were not statistically significant(P>0.05).The rates of MR-TB,PDR-TB,MDR-TB,XDR-TB,and total resistance isolates of MTB clinical isolates were 14.46%,5.16%,5.16%,4.58%,and 1.29%,respectively.he pediatric group had a higher MR rate(15.4%)than the adult and geriatric groups,while the adult and geriatric groups had higher MDR rates(5.0%and 5.0%,respectively).The geriatric group also had a higher XDR rate(2.1%),with statistically significant differences(P<0.001).The rates of MR-TB(14.8%),PDR-TB(5.3%),MDR-TB(4.7%),XDR-TB(1.4%),ofloxacin resistance(11.33%)and rifampicin resistance(6.92%)of MTB clinical isolates were higher in patients from the Pearl River Delta than in other regions of Guangdong Province,with statistically significant differ-ences(P<0.001).Conclusion According to the data from the surveillance sites,the epidemiological trend of drug-resistant TB in Guangdong Province is leveling off during the period 2014-2020.However,the incidence of drug-resistant TB is higher in specific populations(e.g.children and the elderly),and the incidence of drug-resistant TB and the rate of drug resistance to drugs in focus are higher in the Pearl River Delta than in other regions of Guang-dong Province,necessitating further investigation and the development of novel prevention and control strategies.

Objective:To compare Al 18F-1, 4, 7-trizacyclononane-1, 4, 7-triacetic acid (NOTA)-fibroblast activation protein inhibitor (FAPI)-04 PET/CT with 18F-FDG PET/CT in the evaluation of patients with initial gastric cancer. Methods:Twenty patients (13 males, 7 females, age: 27-77 years) with histologically proven gastric cancer were recruited prospectively between March 2021 and July 2022 in the First Affiliated Hospital of Zhengzhou University. Each patient underwent both 18F-FDG and Al 18F-NOTA-FAPI-04 PET/CT within one week. SUV max, tumor background ratio (TBR) and positive detection rate of the two methods were compared (Wilcoxon signed rank sum test, McNemar χ2 test). Results:Al 18F-NOTA-FAPI-04 showed higher SUV max and TBR than those of 18F-FDG in primary tumors (10.2(8.0, 13.7) vs 5.2(3.3, 7.7), z=-3.47, P=0.001; 7.6(5.6, 10.3) vs 2.4(1.8, 3.0), z=-3.85, P<0.001). For the detection of primary gastric cancer, the positive detection rate of Al 18F-NOTA-FAPI-04 PET/CT showed the trend of being higher than that of 18F-FDG PET/CT (95%(19/20) and 75%(15/20); χ2=2.25, P=0.125). For assessing lymph node metastasis, the detection rate of Al 18F-NOTA-FAPI-04 PET/CT was higher than that of 18F-FDG PET/CT (78.9%(101/128) vs 64.8%(83/128); χ2=13.47, P<0.001). The SUV max and TBR of Al 18F-NOTA-FAPI-04 in lymph node were higher than those of 18F-FDG (5.3(3.5, 9.2) vs 2.8(1.8, 4.7), z=-7.31, P<0.001; 4.6(2.6, 6.5) vs 1.7(1.0, 3.0), z=-8.44, P<0.001). For the detection of peritoneal carcinomatosis, Al 18F-NOTA-FAPI-04 PET/CT showed higher peritoneal cancer index (PCI), SUV max, and TBR compared to 18F-FDG PET/CT (PCI: 12.0(3.0, 29.8) vs 5.5(0.5, 17.5), z=-2.22, P=0.026; SUV max: 8.2(4.4, 12.5) vs 2.7(1.9, 4.0); z=-2.52, P=0.012; TBR: 5.1(2.9, 13.3) vs 1.1(0.9, 2.0); z=-2.52, P=0.012). Conclusion:Al 18F-NOTA-FAPI-04 PET/CT outperforms 18F-FDG PET/CT in primary and metastatic lesions of gastric cancer and might be a potential novel modality for imaging patients with gastric cancer.
