Objective To analyze and explicate the conceptual connotations of exercise rehabilitation preferences in stroke patients. Methods A systematic search was conducted across multiple databases including the China National Knowledge Infrastructure (CNKI), the Wanfang Data Knowledge Service Platform, the Chinese Biomedical Literature Database, PubMed, Web of Science, Embase, and CINAHL, with the search period extending from inception to October 2022. In accordance with inclusion and exclusion criteria, eligible literatures were selected, and a comprehensive analysis was performed by Rodgers' evolutionary concept analysis method. Results A total of 34 literatures were included. Exercise rehabilitation preferences for stroke patients encompassed 5 concept attributes: preferences for exercise rehabilitation programs, risk tolerance in rehabilitation, time preferences for engaging in exercises, supervision and support, and confidence and challenges; the antecedents to these preferences included demographic factors, disease-related factors, emotional and psychological factors, external environmental factors, and fatigue; outcomes associated with these preferences included the realization of individualized exercise rehabilitation, improvement in adherence to rehabilitation regimens, increased levels of physical activity, and facilitation of motor function recovery. Conclusion Through the conceptual analysis of exercise rehabilitation preferences in stroke patients, healthcare professionals can better understand its underlying dimensions, thereby enabling more in-depth research and exploration into exercise rehabilitation practices tailored for stroke patients.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To conduct an overview of systematic reviews on the safety and effectiveness of early mobilization in stroke patients.Methods:Systematic reviews of early mobilization in stroke were electronically searched on China National Knowledge Infrastructure, WanFang Data, VIP, Chinese Biology Medicine, Cochrane Library, PubMed, Web of Science, CINAHL, Embase, and the Joanna Briggs Institute Evidence-Based Health Care Center Database. The search period was from database establishment to May 2023. Two researchers independently conducted literature screening, data extraction, and methodological quality evaluation of the included literature, as well as evidence summary and grading.Results:A total of 10 systematic reviews were included. The methodological quality evaluation showed that one article was of medium quality, two articles were of low quality, and seven articles were of extremely low quality. The evidence quality evaluation indicated that there were three pieces of high-quality evidence, 17 pieces of medium-quality evidence, 21 pieces of low-quality evidence, and 17 pieces of extremely low-quality evidence.Conclusions:Early mobilization is beneficial for improving the daily living ability and limb motor function of stroke patients, reducing the incidence of complications, shortening hospital stay, and enhancing their walking ability in the short term. However, the quality of evidence in the systematic review is relatively low, and further improvement is needed in the research design of early mobilization intervention measures to provide strong support for clinical practice.

The epidemiological and spatiotemporal distribution characteristics of human leptospirosis in Zhejiang Province from 2018 to 2022 were analyzed,to provide a scientific basis for formulating leptospirosis prevention and control strategies.Data on leptospirosis were collected from the China Information System for Disease Control and Prevention,and analyzed with descriptive epidemiological methods.ArcMap 10.8 software was used for spatial autocorrelation analysis and visual display of the results.SaTScan 10.1.2 software was used for spatiotemporal scanning,to analyze and describe the spatiotemporal aggrega-tion characteristics of leptospirosis.A total of 255 human cases of leptospirosis were reported in Zhejiang Province from 2018 to 2022,including one death;the average annual incidence was 0.084 3/100 000,and the average annual mortality was 0.000 3/100 000.The highest incidence of leptospirosis in Zhejiang occurred from August to October.Most cases were in middle-aged and older people 45-86 years of age(221 cases,86.67％).The number of cases was highest among people 65-69 years of age(57 cases).The male to female ratio was 4.67∶1.The main occupation was farming(190 cases,74.51％).The cumulative number of cases in Wenzhou and Lishui in 3 years(201 cases)accounted for 78.82％of the total cases.The global spatial auto-correlation analysis from 2018 to 2022 showed that the incidence of leptospirosis in the province presented a positive spatial au-tocorrelation.Local spatial autocorrelation analysis indicated that the"high-high"gathering areas were concentrated primarily in Wenzhou,Lishui,and Taizhou in the mountainous and hilly areas of southern Zhejiang Province.Spatiotemporal scanning anal-ysis revealed three clusters with high incidence in southern Zhejiang Province.The incidence of leptospirosis in Zhejiang Prov-ince showed clear regional clustering and seasonality,and the high incidence area was mainly in the mountainous and hilly areas of southern Zhejiang Province.The cases occurred mainly in middle-aged and older male farmers.Health education among rural resi-dents should be strengthened to prevent potential epidemic risks.

Objective:To explore the genotypes and clinical phenotypes of three families with Liddle Syndrome(LS).Methods:In this study, three young patients with hypertension and hypokalemia were confirmed LS through second-generation sequencing genetic testing. Members of the three families were screened for genes, and genotypes and clinical phenotypes were analyzed.Results:This study identified three patients in Family 1 carrying a possible pathogenic heterozygous variant c. 1859A>G(p.Y620C) in the SCNN1B gene(sodium channel epithelia 1β subunit). Five patients in family 2 and family 3 carried the pathogenic heterozygous variant c. 1789dup(p.R597Pfs*11) in the SCNN1B gene. Following three months of treatment with salt restriction and triamterene, blood pressure and potassium levels returned to normal in all eight patients.Conclusion:LS patients typically present clinically with early-onset hypertension accompanied by hypokalemia, but there is clinical heterogeneity. It is recommended to conduct genetic testing on suspected patients as early as possible to confirm the diagnosis and initiate timely treatment with effective medications so as to reduce the complications of target organs.

Malaria is a global disease affecting a large portion of the world’s population. Although vaccines have recently become available, their efficacies are suboptimal. We generated virus-like particles (VLPs) that expressed either apical membrane antigen 1 (AMA1) or microneme-associated antigen (MIC) of Plasmodium berghei and compared their efficacy in BALB/c mice. We found that immune sera acquired from AMA1 VLP- or MIC VLP-immunized mice specifically interacted with the antigen of choice and the whole P. berghei lysate antigen, indicating that the antibodies were highly parasite-specific. Both VLP vaccines significantly enhanced germinal center B cell frequencies in the inguinal lymph nodes of mice compared with the control, but only the mice that received MIC VLPs showed significantly enhanced CD4+ T cell responses in the blood following P. berghei challenge infection. AMA1 and MIC VLPs significantly suppressed TNF-α and interleukin-10 production but had a negligible effect on interferon-γ. Both VLPs prevented excessive parasitemia buildup in immunized mice, although parasite burden reduction induced by MIC VLPs was slightly more effective than that induced by AMA1. Both VLPs were equally effective at preventing body weight loss. Our findings demonstrated that the MIC VLP was an effective inducer of protection against murine experimental malaria and should be the focus of further development.

Objective: To explore the development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

Objective: To summarize clinical features and our experience of the diagnosis and treatment of laryngocele. Methods: Clinical data of 11 laryngocele patients in department of Otorhinolaryngology Head and Neck Surgery of the Second Affiliated Hospital of Shanxi Medical University from January 2012 to December 2021 were retrospectively reviewed, including 9 men and 2 women, aged from 12 to 75 years, with median age of 56 years. Electronic laryngoscope was performed in 10 of all patients, laryngeal CT in 10 and cervical color ultrasound in 5 before operation.All the operations were performed under general anesthesia, and the external cervical approach was used for external and combined laryngocele. The internal laryngocele was resected by low temperature plasma through transoral endoscopy. Patients were followed up regularly after operation to evaluate the effect. Clinical feature, types of lesions, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eleven laryngocele patients were divided into mixed type (n=6), internal type (n=4) and external type (n=1).Nine patients presented with hoarseness or dysphonia, 7 with cervical mass and 1 with airway obstruction. Surgical resections were done through external cervical approach (n=7)or transoral endoscopic approach (n=4). All the operations were successful and no complication occurred. All cases were followed up from 17 to 110 months. No recurrence was encountered. Conclusions: Laryngocele is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and electronic laryngoscope is essential to evaluate the location, and extent of the lesion, and to make the surgical plan.Complete surgical excision is required. Surgical resection is the only effective method for the treatment of laryngocele.

Myocardial infarction (MI) is one of the leading causes of death in the world. With the improvement of clinical therapy, the mortality of acute MI has been significantly reduced. However, as for the long-term impact of MI on cardiac remodeling and cardiac function, there is no effective prevention and treatment measures. Erythropoietin (EPO), a glycoprotein cytokine essential to hematopoiesis, has anti-apoptotic and pro-angiogenetic effects. Studies have shown that EPO plays a protective role in cardiomyocytes in cardiovascular diseases, such as cardiac ischemia injury and heart failure. EPO has been demonstrated to protect ischemic myocardium and improve MI repair by promoting the activation of cardiac progenitor cells (CPCs). This study aimed to investigate whether EPO can promote MI repair by enhancing the activity of stem cell antigen 1 positive stem cells (Sca-1⁺ SCs). Darbepoetin alpha (a long-acting EPO analog, EPO_anlg) was injected into the border zone of MI in adult mice. Infarct size, cardiac remodeling and performance, cardiomyocyte apoptosis and microvessel density were measured. Lin^- Sca-1⁺ SCs were isolated from neonatal and adult mouse hearts by magnetic sorting technology, and were used to identify the colony forming ability and the effect of EPO, respectively. The results showed that, compared to MI alone, EPO_anlg reduced the infarct percentage, cardiomyocyte apoptosis ratio and left ventricular (LV) chamber dilatation, improved cardiac performance, and increased the numbers of coronary microvessels in vivo. In vitro, EPO increased the proliferation, migration and clone formation of Lin^- Sca-1⁺ SCs likely via the EPO receptor and downstream STAT-5/p38 MAPK signaling pathways. These results suggest that EPO participates in the repair process of MI by activating Sca-1⁺ SCs.
