Objective To explore the preventive effect of multidisciplinary collaborative evidence-based nursing on dysphagia in patients with orotracheal intubation in intensive care unit(ICU)after extubation.Methods A retrospective analysis was performed on 200 patients with orotracheal intubation in ICU who were admitted to Dongguan Traditional Chinese Medicine Hospital between January and December 2023.Of them,96 patients who were admitted to our hospital between January and May 2023 received routine nursing(routine group),104 patients who were admitted to our hospital between June and December 2023 received multidisciplinary collaborative evidence-based nursing(evidence-based group).The incidence of dysphagia after extubation,water swallowing test result,swallowing function measured with M.D.Anderson dysphagia inventory(MDADI),psychological state assessed by connor-davidson resilience scale(CD-RISC),quality of life assessed by swallowing quality-of-life questionnaire(SWAL-QOL),and the incidence of dysphagia complications(aspiration,aspiration pneumonia,and malnutrition)were compared between the two groups.Results The incidence of dysphagia after extubation and the water swallowing test class in the evidence-based group were lower than those in the routine group(both P<0.05).The total score of MDADI and CD-RISC scores in the evidence-based group were significantly higher than those in the routine group(P<0.05),while the SWAL-QOL scores were lower(P<0.05).The incidence of complications in the evidence-based group was significantly lower than that in the routine group(P<0.05).Conclusion Multidisciplinary collaborative evidence-based nursing can effectively reduce the incidence of dysphagia in patients with orotracheal intubation in ICU after extubation,improve swallowing function,psychological state and quality of life,and reduce the incidence of complications.

Background In recent years, radiation diagnosis and treatment technology has been increasingly applied and popularized in the medical field, and the status of radiation health protection has attracted widespread attention. Objective To understand the knowledge, attitude, and behavior of radiological health protection in radiation workers in Jiading District of Shanghai. Methods Convenience sampling method was used to select 441 radiation workers from 33 medical institutions in Jiading District, Shanghai to conduct a questionnaire survey from May to August 2023. Basic information and radiation protection associated knowledge, attitude, and behavior were collected from the study participants, and the scores of knowledge, attitude, and behavior were calculated. Factors affecting the behavior were evaluated by multiple linear regression. Results A total of 441 subjects were included in this study, with an age range of 22-71 years, 53.06% male and 46.94% female. In terms of knowledge, the correct response rate of the study subjects to the seven questions on the basics of radiation protection ranged from 44.22%-96.60%, with the lowest rate of 44.22% for the question on "radiation stochastic effect diseases". The subjects acquired knowledge about radiation hygiene mainly through vocational training (98.41%), and wanted to acquire knowledge mainly about the basics of nuclear and radiation (76.42%). In terms of attitude, the recognition level (strongly agree/agree) of the study subjects on the six attitude questions ranged from 73.47% to 96.37%, in which only 56.92% of the radiological staff at tertiary hospitals believed that the radiation dose they were exposed to at work would be hazardous to their health, and 73.85% believed that it was necessary to participate in training on knowledge of radiological protection, both lower than those in other levels of hospitals. In terms of behavior, the implementation rate (always/often) of the five behavioral questions by the study participants ranged from 75.28% to 91.84%, and there was a statistically significant difference in the total behavioral scores of the study participants by levels of hospitals (P=0.015). The results of multiple linear regression showed that gender, age, and radiation work permit associated with the behavioral scores of the study subjects. Conclusion In Jiading District, Shanghai, the coginitive rate of radiation workers' basic knowledge of theoretical protection still needs to be improved, and occupational training should be carried out in a targeted manner; the attitude of radiation workers varies by levels of hospitals, and the publicity and education of workers at tertiary hospitals in particular should be strengthened; and the supervision and management of male, senior, and non-certified radiation workers in hospitals of different levels should be enhanced.

The American College of Rheumatology (ACR) and the American Association of Hip and Knee Surgeons (AAHKS) convened a writing group to develop a consensus report on the management of anti-rheumatic medication in patients with rheumatic diseases undergoing elective total hip or total knee arthroplasty in June 2022. In particular, the consensus provides significant updates on target synthetic disease modifying anti-rheumatic drugs and perioperative medication management in patients with systemic lupus erythematosus, as well as the addition of newly approved antirheumatic medications for administration. This article will interpret the consensus and provide a reference for the perioperative management of antirheumatic medications for hip and knee arthroplasty in patients with rheumatic diseases in China.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.

OBJECTIVES: To verify the applicability and extensibility of the satisfaction index of basic medical insurance for rural and urban residents, and to explore the mechanism responsible for the satisfaction index in Kunming and Changsha City, and provide references for effective management and policy making. METHODS: A stratified cluster sampling method was conducted. A total of 560 familial decision makers were randomly selected in 24 classes of 14 schools of Kunming and Changsha City. Model reliability was tested by SPSS18.0. In addition, Smart PLS 3.0 was applied to conduct model validity test, calculate the satisfaction index, and to compare the model path coefficients of Kunming and Changsha by multi-group analysis. RESULTS: In the application of the satisfaction index of basic medical insurance for rural and urban residents in Kunming, Cronbach's α of the model was 0.93, split-half reliability coefficient was 0.90, and the latent variable composite reliability coefficient values were more than 0.86; the latent variable average variance extraction (AVE) values were greater than 0.66, and the square root of the AVE of each latent variable (all greater than 0.66) was larger than the correlation coefficient with other latent variables. The factor loading values were greater than 0.70, with statistical significance. The basic health insurance satisfaction index of Kunming and Changsha was 60.40 and 52.05, respectively. The difference between the path coefficient of Kunming and Changsha was not statistically significant except the path from public satisfaction to public loyalty. Perceived value had the largest direct and total effect on public satisfaction latent variable in Kunming City. While the perceived value had the largest direct effect on public satisfaction, and the perceived quality had the largest total effect on public satisfaction in Changsha City. CONCLUSIONS The satisfaction index model reflects the satisfaction of pupils' basic medical insurance for urban and rural residents, and it also shows good reliability and validity in Changsha and Kunming. What's more the model can be extended to the national level to evaluate the satisfaction of basic medical insurance for urban and rural residents for primary school students. The basic health insurance satisfaction index of familial decision makers in Kunming is higher than that of Changsha. There are differences between Kunming and Changsha in the influential mechanism of the satisfaction index of for Chinese pupils with basic medical insurance for rural and urban residents, and the measures taken by the government and relevant departments to improve the satisfaction of basic medical insurance should be based on local conditions.

Objective:To study the orthopedic treatment strategy for hemophilia complicated with musculoskeletal disorders as well as the peri-operative consumption of clotting factor.Methods:Total 338 orthopedic surgeries were performed for 261 patients, average age of 30.6 y (6-65 y) , with hemophilia between January 1996 and December 2019 at our institute. Two hundred and twenty-six patients presented with bleeds within the joints. Sixty-one patients presented with intramuscular bleeds, 45 presented with hemophilic pseudotumors, and six presented with miscellaneous complaints. Strategy of clotting factor replacement therapy was designed as per differences in the level of the operation procedure. Information regarding clinical manifestation, operative strategy, clotting factor consumption, and re-operation for complications was retrospectively recorded. The costs for multiple joint procedure and single joint procedure were studied.Results:We found that 270 of the 338 surgical procedures were major surgical procedures (79.9%) . There were 203 procedures of joint arthroplasty (60%) . Fourteen patients underwent reoperations for local recurrence (4.2%) . The average factor Ⅷ consumption before the surgery was 44.4 ± 8.1 IU/kg. The average FⅧ consumption within postoperative 2 weeks was 40 962 IU (647±177 IU/kg) . Seven type A hemophilic patients developed F Ⅷ inhibitor following the surgical procedure, with an average level of 13.7±11.2 BU/mL. Sixty-eight patients underwent multiple joint procedures under one anesthesia session (26%) . There was no significant difference in the factor consumption between the multiple joint procedure and single joint procedure.Conclusions:Surgical treatment was found to be effective for hemophilic arthropathy and lesion of the musculoskeletal apparatus, with the clotting factor replacement therapy. Multiple joint procedures under one anesthesia were more cost effective for patients with hemophilia, with less factor consumption than staged single joint procedure.

Objective To investigate surgical interventions for periprosthetic joint infection (PJI) after total knee arthroplasty and characteristics of prognosis.Methods Sixty-two patients with PJI after total knee arthroplasty from January 2000 to November 2016 were reviewed retrospectively,included with 17 males and 45 females.The mean age was 66.0± 10.2 years old (37-85).Fourty-nine patients were diagnosed with osteoarthritis,9 with rheumatoid arthritis,2 with secondary ankyloses after suppurative arthritis and 2 with hemophilia arthritis.Forty-one patients underwent unilateral total knee arthroplasties,and 21 bilateral total knee arthroplasties.Characteristics of PJI,including infection types,existence of sinus tract,infectious pathogen,surgical intervention and patients' prognosis,were collected.Results Twenty-four patients underwent open debridement with prothesis retention.In the 14 successful cases,medial time interval between primary total knee arthroplasty and debridement was 33 days.One case of positive Methicillin resistant Staphylococcus aureus culture of joint aspiration,and 1 case formed sinus tract.In 10 cases of failed debridement,the medial time interval was 270 d.Intra-articular culture presented 4 cases of antibiotic resistant bacteria,and 6 cases formed sinus tract.Except for one patient gave up treatment and another received arthrodesis,the other 8 failed cases were all treated with revisions.In 46 revisions,nine patients underwent one-stage revisions.The mean time interval between primary total knee arthroplasty and revision was 15.9± 14.5 d.Intra-articular culture presented 3 cases of antibiotic resistant bacteria,and 1 case formed sinus tract.In the other 37 two-stage revisions,the mean time interval was 1 045.7±1 044.1 d.Intra-articular culture showed 15 cases of antibiotic resistant bacteria,and 12 cases formed sinus tract.The mean follow-up duration was 73.9±48.2 months.At the last follow-up,all patients were free of antibiotics treatment.The mean Knee Society Score (KSS) was 85.9±4.3 after successful open debridement with prothesis retention.The KSS of one-stage revision patients was 78.5±3.3,while that of two stage revision patients was 65.7±7.4.Statistical difference was found among groups (P＜0.05).Conclusion For PJI within 3 weeks after total knee arthroplasty without sinus tract or intra-articular culture of antibiotic resistant bacteria,open debridement with prosthesis retention could be recommended.One stage revision could be applied in infectious cases which appeared between 3 weeks to 1 month after primary surgery or in cases with unstable prostheses found in open debridement.For infectious cases longer than 1 month after primary procedure or those with sinus tract,severe soft tissue deficiency,intra-articular culture of antibiotic resistant bacteria,two-stage revision could be recommended.

Objective To explore the effect of chloroquine on death receptor 5 (DR5) expression of hepatocellular carcinoma Huh7 cells and cell proliferation and apoptosis induced by tumor necrosis factor related apoptosis-inducing ligand (TRAIL).Methods Huh7 cells were divided into four groups:the control group (1∶1 000 dimethyl sulfoxide),TRAIL group (50 μg/L),chloroquine group (10 μmol/L) and TRAIL +chloroquine group (TRAIL 50 μg/L + chloroquine 10 μmol/L).Thiazolyl blue tetrazolium bromide (MTT) assay was used to determine the proliferation activity of cells,immunofluorescence was used to detect the expression of DR5,4',6-diamidino-2-phenylindole (DAPI) staining was used to observe cell apoptosis and Western blot was used to detect the expression of cleaved poly ADP-ribose polymerase (PARP).Results TRAIL treatment could decrease Huh7 cells proliferation activity;when compared with the cell viability in the control group,the cell proliferation inhibition rate of chloroquine group,TRAIL group and TRAIL+ chloroquine group was (89±8) ％,(53±10) ％ and (27±7) ％,respectively;compared with TRAIL group alone,cell proliferation activity was decreased in TRAIL+ chloroquine group (t =3.922,P =0.017).The expression of DR5 was upregulated in chloroquine group,and the cell apoptosis signaling was activated in TRAIL + chloroquine group.The cell apoptosis rate of TRAIL group and TRAIL + chloroquine group was (10.0±2.3) ％ and (20.4±4.0) ％,respectively,and there was a statistical difference (t =3.894,P =0.018).Conclusion Chloroquine can enhance the cell chemosensitivity to TRAIL treatment by upregulating the expression of DR5 in Huh7 cells.
