The Burkholderia cepacia complex (Bcc) comprises a group of genetically related yet phenotypically diverse Gram-negative opportunistic pathogens. These organisms demonstrate significant pathogenicity in immunocompromised populations, particularly cystic fibrosis (CF) and chronic granulomatous disease (CGD) patients, causing severe infections including pneumonia, bacteremia, and urinary tract infections. Notably, Bcc infection in CF patients may progress to acute respiratory failure or the life-threatening "cepacia syndrome". Of particular concern is the widespread nosocomial colonization by Bcc strains coupled with their sophisticated multidrug resistance mechanisms, which contribute substantially to clinical treatment failures. This review systematically examines the epidemiological characteristics, clinical manifestations and resistance mechanisms of Bcc. The review aims to provide evidence-based references for improving accurate diagnosis and enhancing infection control measures against this challenging pathogen.

Heat shock factor 1(HSF1)is a regulatory factor in the cellular stress response.Recent studies have shown that the combination of HSF1 inhibitors and chemotherapeutic drugs can achieve synergistic effects through multiple mechanisms,in-cluding reversing drug resistance,enhancing immune responses,and regulating DNA damage repair and cell death programs.In this article,we review the research progress of anti-tumor effects of HSF1 inhibitor combined with chemotherapeutic drugs.

This article reported a case of autosomal dominant intellectual developmental disorder type 22 caused by a heterozygous mutation in the ZBTB18 gene. At 24 +4 weeks of gestation, prenatal ultrasound indicated a short outer diameter of the fetal corpus callosum and bilateral ventricular dilatation. Whole-genome copy number variation analysis of the fetus showed no abnormalities. Whole exome sequencing (WES) and Sanger sequencing validation of the family revealed the fetus carried a c.1374_1383del(p.S459*) heterozygous mutation in the ZBTB18 gene (NM_205768.3), which was neither phenotypically present nor genotypically detected in the parents, suggesting a de novo mutation. Based on the clinical manifestations, the fetus was diagnosed with autosomal dominant intellectual developmental disorder type 22. After genetic counseling, the pregnant woman opted for termination of the pregnancy. This case highlights the correlation between prenatal ultrasonic detection of callosal dysgenesis and lateral ventricular enlargement and intellectual developmental disorders caused by gene mutations. Furthermore, it expands the mutation spectrum of the ZBTB18 gene, thereby facilitating prenatal diagnosis and genetic counseling.

The cultivation of top innovative nursing talents with Chinese characteristics in the new era lends critical support to the accomplishment of the strategic goal of the Healthy China Initiative.Herein,we reviewed the historical development of nursing science in China,clarified the conceptual framework of nursing science with Chinese characteristics in the new era,and identified the essential qualities and competencies required for top innovative nursing talents.Furthermore,we analyzed the mission and challenges in cultivating these nursing talents,and put forward new approaches,including formulating new ethics and political education theories specific to nursing science with Chinese characteristics,establishing a cross-disciplinary educational model of Nursing+X,and creating a new nursing talent cultivation ecosystem adapted to the era of human-machine symbiosis.This study provides theoretical insights into the cultivation of top innovative nursing talents who align their development well with national strategic needs,embody patriotism,and possess a strong sense of contemporary responsibility.

Objective:To evaluate the effect of controlled low central venous pressure (CLCVP) induced by milrinone on intraoperative cerebral blood flow in the patients undergoing laparoscopic hepatectomy.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, regardless of gender, scheduled for elective laparoscopic hepatectomy, with body mass index of 18-30 kg/m 2, aged 18-64 yr, were divided into 2 groups ( n=40 each) by a random number table method: nitroglycerin group (X group) and milrinone group (M group). After the start of surgery, milrinone 0.5 μg·kg -1·min -1 was continuously infused in group M and nitroglycerin 0.5-1.5 μg·kg -1·min -1 was continuously infused in group X to maintain central venous pressure (CVP)<5 cmH 2O. Norepinephrine 0.01-0.10 μg·kg -1·min -1 was intravenously injected during operation to maintain mean arterial pressure at 60-90 mmHg. Norepinephrine 8-16 μg was intravenously injected when necessary. At 10 min after tracheal intubation (T 1), after establishment of pneumoperitoneum (T 2), at 5 and 30 min after CVP reached the target value (T 3, T 4), at 5 min after CVP returned to normal value (T 5) and at the end of surgery (T 6), the internal carotid artery mean blood flow velocity, internal carotid artery blood flow, cardiac output, and cardiac index were recorded. The surgical field score, consumption of intraoperative norepinephrine, fluid input and output, and occurrence of adverse reactions at 7 days after operation were recorded. Results:Compared with group X, the cardiac output, cardiac index, internal carotid artery mean blood flow velocity and internal carotid artery blood flow were significantly increased, the consumption of intraoperative norepinephrine was decreased, and the surgical field score was increased at T 3-5 in group M ( P<0.05). There was no significant difference in the intraoperative fluid intake and output and incidence of postoperative adverse reactions at each time point between the 2 groups ( P>0.05). Conclusions:Compared with nitroglycerin-induced CLCVP, milrinone-induced CLCVP can improve the reduction in intraoperative cerebral blood flow in the patients undergoing laparoscopic hepatectomy to some extent.

【Objective】 To evaluate the clinical efficacy and safety of platelet-rich plasma(PRP) in acute achilles tendon injury by meta-analysis. 【Methods】 Literature on clinical randomized controlled trial of PRP in the treatment of acute achilles tendon injury from Wanfang database, CNKI, VIP database, The Chinese Biological Literature Database, The Chinese Clinical Trials Registry, PubMed, Embase, Cochrane and The US Clinical Trials Registry as of August 2023 were retrieved. The control group received conventional treatment for acute achilles tendon injury, while PRP treatment group received additional PRP treatment. The primary outcome measure was visual analogue pain scale, and the secondary outcome measures were the achilles tendon fracture score, maximum heel rise height, calf circumference and ankle range of motion. The quality of the literature was assessed using the Cochrane manual, and a meta-analysis of qualified literature was performed using RevMan 5.3 software. 【Results】 Seven articles were finally included, involving 421 patients with acute achilles tendon injury, including 212 patients in the PRP treatment group, and 209 patients in the conventional treatment group. The results of meta-analysis showed that there was no difference between the conventional treatment group and the PRP treatment group in terms of the visual analogue pain scale(SMD=-0.44, 95%CI: -0.94~0.06, P>0.05), calf circumference (MD=1.14, 95% CI: -1.56-3.84, P>0.05), ankle joint toe flexion range of motion (SMD=1.85, 95%CI: -1.38-5.09, P>0.05), ankle dorsiflexion range of motion(SMD=2.61, 95%CI: -0.95-6.17, P>0.05), achilles tendon fracture score (MD=-5.60, 95%CI: -15.36-4.16, P>0.05) and the maximum heel rise height (MD=-2.48, 95%CI: -5.30-0.33, P>0.05). And there was no difference in the incidence of adverse reactions between the two groups (X²=2. 455, P>0.05). 【Conclusion】 PRP injection for acute achilles tendon injury does not improve the biomechanical and clinical outcomes of patients, and the use of PRP does not increase the occurrence of adverse reactions.

To prepare a lipid nanoparticle (LNP)-based subunit vaccine of Mycobacterium tuberculosis (Mtb) antigen EsxV and study its immunological characteristics, the LNP containing EsxV and c-di-AMP (EsxV: C: L) was prepared by thin film dispersion method, and its encapsulation rate, LNP morphology, particle size, surface charge and polyphase dispersion index were measured. BALB/c mice were immunized with EsxV: C: L by nasal drops. The levels of serum and mucosal antibodies, transcription and secretion of cytokines in lung and spleen, and the proportion of T cell subsets were detected after immunization. EsxV: C: L LNPs were obtained with uniform size and they were spherical and negatively charged. Compared with EsxV: C immunization, EsxV: C: L mucosal inoculation induced increased sIgA level in respiratory tract mucosa. Levels of IL-2 secreted from spleen and ratios of memory T cells and tissue-resident T cells in mice were also elevated. In conclusion, EsxV: C: L could induce stronger mucosal immunity and memory T cell immune responses, which may provide better protection against Mtb infection.
