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.

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.

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 Aiming to develop a distance-adaptive visual function self-examination system based on tablet computers and evaluate its accuracy.Methods Utilizing ArUco technology on a tablet device equipped with the camera,a system was developed to assess visual functions by identifying QR codes within a 2-meters range for real-time ranging.This system integrates various visual function tests,including visual acuity test(conventional visual acuity test and high-pass visual acuity test with varying contrasts),accommodative amplitude test,and visual field test at the foveal(5°).A total of 22 healthy subjects(44 eyes)participated in visual function assessments,with 6 subjects undergoing visual acuity tests at varying distances(1 m,1.25 m,1.6 m,2 m)and accommodative amplitude tests under both refractive correction and simulated undercorrection of-3.00D.The program distance and actual distance were compared,the consistency of visual acuity outcomes for identical optotype at different distances were assessed,the accommodative amplitude under refractive correction and undercorrection were analyzed,the repeatability of accommodative amplitude outcomes was evaluated using Intraclass Correlation Coefficient(ICC),and the contrast threshold and efficacy of visual field test outcomes were analyzed.Results The program distance and actual distance showed good agreement.High-pass visual acuity tests with the same contrast showed no significant differences at different distances(P?>?0.05),while conventional visual acuity tests showed significant differences at distances of 0.9 to 1.1 meters compared to other distances(P?

Integrase inhibitors (INSTIs) are the newest class of antiretroviral drug which are available to people living with the human immunodeficiency virus (HIV). Since 2007, five types of INSTIs have been marketed: Raltegravir, Elvitegravir, Dolutegravir, Bictegravir and Cabotegravir, all of which were approved by the US Food and Drug Administration (FDA) for use in the initiation of antiretroviral therapy (ART) in treatment-na?ve individuals. Compared with other types of antiretroviral drugs, INSTIs have better efficacy and tolerability, so many countries around the world have listed INSTIs-containing regimens as the preferred regimen for HIV ART. In recent years, with the widespread use of INSTIs, some research data suggest that INSTIs may have some adverse effects (AEs), such as central nervous system symptoms, abnormal lipid metabolism, weight gain, abnormal liver and kidney function, etc. This review summarizes the current use of INSTIs in people living with the HIV, and highlights the clinical efficacy and their AEs among the five types of INSTIs in China.

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.

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 This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Objective To investigate the effects of α7 nicotinic acetylcholine receptor (α7nAChR) on CD11b, IL-1β, IL-18 and TNF-α in acute respiratory distress syndrome (ARDS) mice. Methods A total of 40 healthy and clean male Balb/C mice (6 weeks old) were randomly divided into normal group (N group), normal saline control group (NS group), ARDS group (A group), and ARDS mice treated with nicotinic acetylcholine receptor agonist after bilateral cervical vagotomy group (J group), with 10 mice in each group. The right lung structure of mice in each group was observed by hematoxylin-eosin (HE) staining, the lung tissue wet weight/body weight ratio (LWW/DW ratio) was detected, and the percentage of CD11b in the alveolar lavage fluid of mice was detected by flow cytometry. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of IL-1β mRNA, IL-18 mRNA and TNF-α mRNA in left lung tissue. Serum IL-18 was determined by enzyme-linked immunosorbent assay (ELISA) and double antibody sandwich method. Results HE staining of the right lung of mice in group N and NS showed normal structure, while the lung interstitial of mice in group A showed a large number of inflammatory cells infiltrated, alveolar wall thickened, alveolar structure destroyed and alveolar cavity fused. The alveolar structure of mice in group J was intact, with a little damage and alveolar cavity. The percentage of CD11b in alveolar lavage fluid in group A was higher than that in the other three groups, and the difference was statistically significant compared with group N, NS and J, respectively (P<0.05). The expressions of IL-1β mRNA, IL-18 mRNA and TNF-α mRNA in the left lung of mice in group J were statistically significant compared with those in group N, NS and A (P<0.05), and the serum IL-18 level of mice in group A was higher than that in the other three groups, and the differences were statistically significant compared with groups N, NS and J, respectively (P<0.05). Conclusions Activation of α7nAChR can directly inhibit the release of CD11b in lung tissue and reduce the accumulation of inflammatory factors. Simultaneously, it can also directly inhibit the expression of IL-β1 mRNA, IL-18 mRNA and TNF-α mRNA in lung tissue and the release of IL-18, thus inhibiting the inflammatory response of ARDS and alleviating the pathological changes of ARDS.
