Objective:To evaluate the effect of esketamine on caspase-11-mediated non-canonical pathway pyroptosis in sepsis-induced acute lung injury in rats.Methods:Eighteen SPF healthy Sprague-Dawley rats, aged 8-12 weeks, weighing 280-320 g, were divided into 3 groups ( n=6 each) using a random number table method: sham operation group (Sham group), cecal ligation and puncture (CLP) group and CLP+ esketamine group (CLP+ ES group). Sepsis was induced by CLP in anesthetized animals. Esketamine 10 mg/kg was injected via the tail vein immediately after development of the model, and the equal volume of normal saline was injected via the tail vein in the other two groups. At 24 h after development of the model, the rats were sacrificed under anesthesia, and the lung tissues and blood samples were taken. The wet to dry lung weight ratio (W/D ratio) was calculated, and the pathological changes were observed and the lung injury was scored. The expression of caspase-11, gasdermin D-N (GSDMD-N), phosphorylated phosphatidylinositol 3-kinase (p-PI3K) and phosphorylated protein kinase B (p-AKT) was detected by Western blot. The expression of caspase-11 and GSDMD-N mRNA was detected by quantitative real-time polymerase chain reaction. The serum concentration of interleukin-1β (IL-1β) was determined by enzyme-linked immunosorbent assay. Results:Compared with Sham group, the lung injury score and W/D ratio were significantly increased, the expression of caspase-11 and GSDMD-N protein and mRNA was up-regulated, the expression of p-PI3K and p-AKT was down-regulated, and the concentration of IL-1β was increased in CLP group ( P<0.05). Compared with CLP group, the lung injury score and W/D ratio were significantly decreased, the expression of caspase-11 and GSDMD-N protein and mRNA was down-regulated, the expression of p-PI3K and p-AKT was up-regulated, and the concentration of IL-1β was decreased in CLP+ ES group ( P<0.05). Conclusions:The mechanism by which esketamine alleviates sepsis-induced acute lung injury may be related to the inhibition of caspase-11-mediated non-canonical pathway pyroptosis in rats.

Objective:To evaluate the clinical equivalence between a domestic calcipotriol/betamethasone dipropionate ointment and the originator product in the treatment of stable plaque psoriasis.Methods:A multicenter, randomized, double-blind, three-arm, parallel-group, active- and placebo-controlled study was conducted, and 449 patients aged 18 - 65 years with stable plaque psoriasis were enrolled from 25 hospitals (such as the First Affiliated Hospital of China Medical University). Eligible patients had a baseline physician's global assessment (PGA) score of ≥ 3 points, baseline body surface area (BSA) involvement of 5% - 30%, and a target lesion psoriasis area and severity index (TL-PASI) for plaque elevation of ≥ 3 points. Participants were randomly assigned in a 2:2:1 ratio to the test group ( n = 179), reference group ( n = 180), and placebo group ( n = 90), and applied the domestic calcipotriol/betamethasone dipropionate ointment, originator product, and ointment base respectively, once daily in the evening for 4 weeks. Efficacy and safety were assessed at weeks 1, 2, and 4. The primary efficacy endpoints were the treatment success rates and clinical success rates in each group at week 4. The per-protocol set (PPS) was used for the primary efficacy analysis, and the intention-to-treat (ITT) set for supplementary efficacy analysis. Equivalence between the test and reference preparations was tested using the Cochran-Mantel-Haenszel method adjusted for randomization strata. Superiority of the test and reference preparations over the placebo was also tested. Measurement data were compared among the 3 groups using analysis of variance or non-parametric tests, while treatment success rates, clinical success rates, and incidence rates of adverse reactions were compared using the chi-square test. Results:The ITT, PPS, and safety sets included 447, 420, and 448 patients, respectively. In the ITT set, patients were aged 43.6 ± 12.8 years, including 320 (71.6%) males and 127 (28.4%) females, and the disease duration was 11.21 ± 9.05 years; 316 (70.7%) had a PGA score of 3 points and 131 (29.3%) had a PGA score of 4 - 5 points. No significant differences in the baseline characteristics (including age, sex, disease duration and disease severity) were observed among the 3 groups (all P > 0.05). Based on the PPS analysis, the treatment success rates were 57.9% (99/171) in the test group, 50.3% (86/171) in the reference group, and 7.7% (6/78) in the placebo group, and the clinical success rates were 57.9% (99/171), 50.3% (86/171), and 10.3% (8/78), respectively; both the test and reference groups were superior to the placebo group in both treatment and clinical success rates (all P < 0.001) ; the rate differences for treatment success (90% confidence interval [ CI]: -1.3% - 16.4%) and clinical success (90% CI: -1.3% - 16.3%) between the test and reference groups were entirely within the pre-defined equivalence margin (-20% - 20%). Subgroup analyses by baseline PGA scores: for patients with a baseline PGA score of 3 points, the treatment success rates in the test, reference, and placebo groups were 60.8% (73/120), 52.1% (62/119), and 11.1% (6/54), respectively, and the corresponding clinical success rates were 61.7% (74/120), 53.8% (64/119), and 13% (7/54), respectively; the test and reference groups did not differ significantly in treatment or clinical success rates (both P > 0.05), but both showed higher success rates than the placebo group (all P < 0.001) ; the results of statistical comparisons among the 3 groups in patients with a baseline PGA score of 4 - 5 points were consistent with those observed in patients with a baseline PGA score of 3 points. The percentage reductions in PGA and TL-PASI scores from baseline to weeks 1, 2, and 4 showed significant differences among the 3 groups, which were significantly higher in the test and reference groups than in the placebo group (all P < 0.001), but did not differ between the test and reference groups (all P > 0.05). The primary adverse reactions were local skin reactions, such as pruritus, pain, and erythema. The incidence rates of adverse reactions were 8.9% (16/179) in the test group, 7.3% (13/179) in the reference group, and 7.8% (7/90) in the placebo group, with no significant difference among the 3 groups ( P > 0.05) . Conclusions:The domestic calcipotriol/betamethasone dipropionate ointment demonstrated clinical equivalence to the originator product in the treatment of stable plaque psoriasis, and the two agents exhibited comparable efficacy for patients with varying degrees of disease severity, and were comparable in the speed and degree of clinical improvement, with similar favorable safety profiles.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the human immunodeficiency virus (HIV) screening status and the resulting residual risk (RR) among blood donors across 17 provincial blood centers in China.Methods:This study used a cross-sectional study. Data on HIV infection markers per 100 000 first-time donors (FD) and repeat donors (RD) from January 2015 to December 2024 were extracted from the National Blood Establishment Performance Comparison Information Management System. Questionnaires were used to collect each center′s HIV screening strategy, algorithm, serological test (ST) kit manufacturers, gray-zone setting for ST, and nucleic acid test (NAT) modality, method, and platform. The incidence-window-period model was used to calculate the residual risk for first-time donors (RR FD), repeat donors (RR RD), and total donors (RR TD) at each center. Horizontal and vertical analysis of RR FD, RR RD, and RR TD across centers and years were performed. Results:All 17 centers applied the same HIV screening strategy which was two rounds of ST followed by one round of NAT. Eight of them operated a single screening algorithm, six employed two algorithms and three used three. Eleven centers used both imported and domestic ST kits, five relied on domestic ST kits only, and one used imported ST kits only, while four centers never set a grey zone for ST throughout the decade. For NAT modalities, eight centers adopted both individual nucleic acid test (ID-NAT) and minipool nucleic acid test (MP-NAT), eight used MP-NAT only and one used ID-NAT only. Seven centers combined transcription mediated amplification (TMA) and polymerase chain reaction (PCR), nine used PCR only and one used TMA only, and fourteen centers ran both imported and domestic NAT systems, two used imported systems only and one used a domestic system only. Over the ten-year period, the mean RR FD across the centers ranged from 2.22 to 12.33 per 10 6 person-years, RR RD from 0.83 to 3.29 per 10 6 person-years and RR TD from 1.59 to 9.29 per 10 6 person-years, with center Z4 consistently showing the lowest values for all three metrics and center U4 recording the highest RR FD and RR TD, while center D2 had the highest RR RD. In 2024 compared with 2015, eleven centers achieved a lower RR FD and ten centers achieved lower RR RD and RR TD. The RR FD and RR TD of centers W2 and U4 displayed pronounced fluctuations and an upward trend in recent years. Conclusions:The 17 provincial blood centers maintain consistent HIV screening strategies, while demonstrating variations in screening algorithm, ST kit manufacturers, NAT modalities, methods, and platform. And the RR FD, RR RD, and RR TD differ across centers. Although most centers show declining trend in RR over the ten-year period, some centers exhibite data fluctuations with a rising trend, suggesting potential for further optimization of HIV screening protocols.

The integrin alpha 2（ITGA2）gene locates on chromosome 5q11.2，encodes the α 2 subunit of the integrin family.The α 2 subunit is found on many cell surfaces.The α 2 subunit plays an important role in the regulation of platelet aggregation，cell migration，cell proliferation and angiogenesis.Through a wide range of studies conducted in recent years，researchers have discovered that this gene is linked to some diseases，such as rheumatoid arthritis，pediatric sickle cell disease，Kawasaki disease，malignant tumor and biliary atresia.These studies have contributed to the early identification of diseases associated with this gene and the exploration of diagnostic and therapeutic solutions for them.This article reviews the advancements in research concerning the association of ITGA2 gene with various diseases.

Kawasaki disease（KD）is an acute systemic vasculitis primarily affecting small- and medium-sized arteries in children，with widespread inflammation as the major pathological hallmark. A subset of patients with KD exhibit resistance to high-dose intravenous immunoglobulin（IVIG）therapy，which significantly increases the risk of developing severe cardiovascular complications，particularly coronary artery lesions（CAL）. Interferon gamma-inducible protein 10（IP-10），a chemokine，exerts its biological functions by binding to its specific receptor，chemokine receptor 3（CXCR3）. In the relevant research on KD，the association between IP-10 and IP-10 gene polymorphism with KD has garnered significant attention from both domestic and international researchers. This article reviews the recent research progress on the relationship between IP-10，its gene polymorphism and KD，with the aim of providing references for the pathogenesis，prevention，treatment and prognosis of KD.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective:To investigate the clinical features and etiologies of hospitalized patients with spike-and-wave activation in sleep(SWAS).Methods:Case-series study.The clinical features and etiologies of patients diagnosed with SWAS in the Department of Neurology, Capital Center for Children′s Health, Capital Medical University from September 2016 to March 2023 were retrospectively analyzed.The measurement data were analyzed by normality testing, and those conforming to the normal distribution were characterized by Mean± SD deviation.After the homogeneity test of variance, either the independent sample t test or the completely random analysis of variance (ANOVA) was employed for data comparison between groups.If the results of ANOVA were statistically significant, the LSD test was utilized for pairwise comparison. Results:(1)Basic data: a total of 140 patients with SWAS were included, with the onset age of (7.4±2.1) years.There were 134 cases (134/140, 95.7%) complicated by epilepsy, and the age of epilepsy onset was (5.3±2.2) years.Seventy-four cases (74/137, 54.0%) had self-limited epilepsy and centrotemporal spikes.Twenty-one cases (21/137, 15.3%) had epileptic encephalopathy and SWAS.Eight cases (8/137, 5.8%) had developmental and epileptic encephalopathy and SWAS.Pulse Methylprednisolone therapy, Clonazepam or Clobazam, callosotomy, and left temporo-parietal-occipital craniotomy for epileptogenic lesion resection were effective in 20 cases (20/32, 62.5%), 3 cases (3/13, 23.1%), 1 case (1/2, 50.0%) and 1 case, respectively.One patient achieved development improvement and a decrease in discharge index after vagus nerve stimulation.(2) Etiologies: ①Genetic etiology: 6 patients carried pathogenic or suspected pathogenic mutations, including GRIN2A (c.87_106dupGGGTCCCCCCGCGCTAAATA/p.I36Rfs*6), GRIN2A (c.2069C>T/p.T690M), CREBBP (c.4844A>G/p.N1615S), KAT6A(c.2203C>T/p.R735X), GRIN1 (c.2326_2327insACCTCT-GGAAGCAGAACGTCTCCCTGTCCA/p.S775_I776insNLWKQNVSLS) and MECP2 (c.916C>T/p.R306C).Among them, there were no reports on the association of CREBBP and KAT6A with SWAS.②Structural etiology: there were 7 cases with perinatal brain injury and 1 case with bilateral temporo-parietal gyrus.③Metabolic etiology: 1 patient with cerebrotendinous xanthomatosis carried the pathogenic gene CYP27A1 (c.379C>T/p.R127W, c.1415G>C/p.G472A), which was not related to SWAS.④Infectious etiology: 1 case had congenital cytomegalovirus infection.⑤ Immune etiology: 1 case had autoimmune encephalitis.⑥ There were 123 cases with unknown etiologies.(3) Etiologies and clinical characteristics: SWAS occurred earlier in patients with structural etiology than that in patients with unknown etiologies ( F=4.478, P<0.05).The proportions of discharge index ≥85% ( χ2=10.079, P<0.05) and encephalopathy ( χ2=9.385, P<0.05) were higher in patients with genetic etiology than those in patients with unknown etiologies.(4) Discharge index: the patients were divided into a group with a discharge index ≥85% and a group with a discharge index < 85%.Compared with the latter group, the former group had a higher proportion of developmental retardation ( χ2=15.976, P<0.001), suffered epilepsy ( t=-3.498, P<0.05) and SWAS at a younger age ( t=-2.044, P<0.05), and used more types of antiepileptic drugs ( t=2.079, P<0.05).(5) Neurodevelopmental outcomes: 21 patients had neurodevelopmental disorders and 75 had normal neurodevelopment. Conclusions:There are various etiologies for encephalopathy or epilepsy complicated by SWAS.The patients with structural etiology may develop SWAS at a younger age, whereas those with a clearly identified pathogenic gene may exhibit a higher discharge index and a higher rate of encephalopathy.When patients present with encephalopathy or refractory epilepsy, surgical treatment should be considered if structural lesions are found.The proportion of developing encephalopathy in patients with a discharge index ≥85% is the same as that in patients with a discharge index <85%.However, the patients with a higher discharge index develop epilepsy and SWAS at a younger age, and are more difficult to treat.

Objective:To gain an in-depth understanding of the psychological safety experiences and changes of new nurses in Neurosurgery Department, providing insights for improving their psychological safety.Methods:A purposive sampling method was used to select new nurses from the Neurosurgery Department at Zhejiang Enze Medical Center Enze Hospital in July to August 2023. Semi-structured interviews were conducted, and Colaizzi's 7-step analysis method was applied to organize and analyze the interview data, summarizing and refining the themes.Results:A total of eleven new nurses from the Neurosurgery Department were included in the study. A total of five themes were identified: insufficient awareness of psychological safety, self-doubt, lack of interpersonal safety, fear and worry, and coping and adaptation.Conclusions:New nurses in Neurosurgery Department often experience a lack of psychological safety during their development. It is crucial to focus on their stage-specific characteristics, enhance new nurse training, create a safe environment, assist them in adopting correct coping strategies, and improve their mental health.

Objective:To explore the predictive value of systemic immune inflammation index combined with stress response index for postoperative urinary tract infection in patients with complicated kidney stones.Methods:From June 2021 to June 2023,97 patients who underwent treatment for urinary tract infection after complex kidney stone operation in Cangzhou Hospital of Integrated Traditional and Western Medicine were selected as infected group,and 87 patients who did not develop urinary tract infection after complex kidney stone operation were selected as uninfected group.Systemic immunoinflammatory index(SII),neutrophils,lympho-cyte,platelet,malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT)levels were detected.Multivariate Logistic regression analysis was performed to analyze risk factors of postoperative urinary tract infection,and ROC curve was drawn to analyze the predictive value of SII,MDA,SOD and CAT alone and combined detection for postoperative urinary tract infection in patients with complex kidney stones.Results:Compared with uninfected group,levels of SII,neutrophils and MDA were increased in infected group,while levels of SOD and CAT were decreased(P<0.05).Levels of lymphocytes and platelets were decreased,the difference was not statistically significant(P>0.05).Multivariate Logistic regression analysis showed that presence of urinary tract history,opera-tion time≥100 min,urinary catheter retention time≥7 d,presence of preoperative urinary tract infection,stone load≥1 000 mm2,combined renal dysfunction,and preoperative blood glucose≥6.15 mmol/L were main risk factors for postoperative urinary tract infection in patients with complex kidney stones.ROC curve showed that combined detection was significantly more effective than single detec-tion of SII,MDA,SOD and CAT in the diagnosis of postoperative urinary tract infection in patients with precomplex kidney stones.Conclusion:Patients with urinary tract infection after complicated kidney stones have increased SII and MDA,decreased SOD and CAT levels,and the abnormal increased or decreased expression level are the predictors of risk of urinary tract infection after compli-cated kidney stones,which may be related with the diagnosis,development and prognosis of the disease.
