Antibiotic adjuvants offer a promising strategy for restoring antibiotic sensitivity, expanding antibacterial spectra, and reducing required dosages. Previously, compound 15 was identified as a potential adjuvant for Polymyxin B (PB) against multidrug-resistant (MDR) Pseudomonas aeruginosa DK2; however, its clinical utility was hindered by high cytotoxicity, uncertain in vivo efficacy, and an unclear synergetic mechanism. To address these challenges, we synthesized and evaluated a series of novel benzamide derivatives, with A22 emerging as a particularly promising candidate. A22 demonstrated potent synergistic activity to PB, minimal cytotoxicity, improved water solubility, and broad-spectrum synergism of polymyxins against various clinically isolated MDR Gram-negative strains. In vivo studies using Caenorhabditis elegans and mouse models further confirmed the efficacy of A22. Moreover, A22 effectively suppressed the development of PB resistance in Pseudomonas aeruginosa DK2. Mechanistic investigations revealed that A22 enhances polymyxins activity by inducing reactive oxygen species production, reducing ATP levels, increasing NOX activity, and inhibiting biofilm formation, leading to bacterial death. These findings position A22 as a highly promising candidate for the development of polymyxin adjuvants, offering a robust approach to combating MDR Gram-negative bacterial infections.

Objective: To analyze the association of 24 h activity behaviors and physical health of primary school students, so as to provide a reference for promoting the physical health of children and adolescents. Methods: From May to June, 2023, by stratified random sampling method, 583 primary school students aged 7-12 were selected from Tianjin for physical health examination. ActiGraph GT3X+ was used to measure their 24 h activity behaviors for 7 d, and their mental health and 24 h activity behaviors were analyzed by gender and grade. LASSO regression was applied for assessing the impact of 24 h activity on their health. Results: The compliance rate of seated forward bending (93.12%) were higher in boys than girls (91.86%), and the differences were statistically significant ( χ 2=4.53, P <0.05). Sleep time ( β =0.06), light intensity physical activity (LPA) time ( β =0.11), and moderate to vigorous physical activity (MVPA) time ( β =0.14) were positively correlated with physical fitness, whereas sedentary behavior (SB) time ( β =-0.08) were negatively correlated with physical fitness, and MVPA time had a positive effect on physical health of children and adolescents, followed by LPA time; while sleep time also had a positive effect , and SB time had a negative effect ( P <0.05). Conclusions Primary school students are generally faced with low physical activity level and high SB time, and MVPA and LPA have a significant impact on physical health. Therefore, it is crucial to develop personalized and differentiated physical activity promotion policies and interventions for primary school students with different classmates and gender.

Objective:To explore the effectiveness of applying the ADDIE (analysis, design, develop, implement, evaluate) Model in clinical teaching for nursing interns in spine surgery department.Methods:Using a convenience sampling method, 44 nursing interns in the Department of Orthopedics at Peking Union Medical College Hospital were selected as the control group from July 2021 to May 2022, and were taught using traditional methods. From July 2022 to May 2023, 45 nursing interns were selected as the observation group, and a teaching team was formed to design a training program based on the five stages of the ADDIE instructional design model. This program was tailored to improve the overall clinical competence of the spinal surgery nursing interns. After training, the teaching effects were evaluated based on knowledge test scores, skills test scores, overall clinical competence, and teaching satisfaction.Results:After the training, the skills test scores in specialized nursing for the observation group were (94.87±1.10) points, higher than the control group's (93.98±1.41) points, with a statistically significant difference ( P<0.01). The observation group also scored higher than the control group in clinical judgment, organizational effectiveness, overall performance, and total score in the Mini-Clinical Evaluation Exercise, with statistically significant differences ( P<0.01). Additionally, the observation group reported higher satisfaction with the teaching plan and methods compared to the control group ( P<0.05) . Conclusions:Clinical teaching for spinal surgery nursing interns based on the ADDIE instructional design model can improve their specialized practical skills and overall clinical competence. The interns also expressed a high level of acceptance for this teaching design model.

Objective:To summarize the clinical manifestations, gene variations, diagnosis and treatment of 3 cases with SLC35A2 variations characterized by congenital glycosylation disorder Ⅱm (CDG Ⅱm). Methods:A total of 3 patients admitted to the Department of Pediatrics of Xiangya Hospital of Central South University in China from 2018 to 2020 were examined in detail. The studies till January 2022 were searched with key words of "congenital disorders of glycosylation Ⅱm", " SLC35A2" and "CDG Ⅱm" in both English and Chinese in the databases of China National Knowledge Infrast Ructure (CNKI), Wanfang, Online Mendelian Inheritance in Man and PubMed, and the clinical manifestations, genetic variation, treatments and prognosis of patients with SLC35A2 mutation were summarized. Results:The patients all presented with intractable infantile spasm and global developmental delay, onset in infancy. A variety of antiepileptic treatments had temporary and partial efficacy. Otherwise, proband 2 and 3 presented with abnormal glutamic-pyruvic transaminase and increased platelets. Funduscopy showed dysplasia of the retinal pigment epithelium in both eyes, and they both received D-galactose treatment. A total of 22 relevant case reports, including 99 patients, were collected. The 99 patients all were heterozygous mutations, and a total of 75 different variation sites were reported. The clinical manifestations were characterized by global developmental delay or mental retardation ( n=89), epileptic seizure ( n=75), hypotonia ( n=57), facial deformity ( n=57), skeletal abnormality ( n=50), visual impairment ( n=42), elevated glutamic-pyruvic transaminase ( n=31), gastrointestinal symptoms ( n=28), skin deformity ( n=26), microcephaly ( n=23) and congenital heart disease ( n=12). Craniocerebral magnetic resonance imaging may be normal in the early stage. With age, magnetic resonance imaging may show abnormal white matter signals, brain atrophy, dysplasia of corpus callosum, delayed myelination, enlargement of lateral ventricle, brain stem atrophy and so on. Studies have shown that galactose treatment may be effective. Conclusions:SLC35A2 variants lead to CDG Ⅱm, whose clinical manifestations mainly include epileptic encephalopathy and global developmental delay. Multiple antiepileptic therapies can temporarily or partially control seizures, while oral galactose may improve the clinical symptoms, showing its prospect as a dietary therapy.

Objective:To investigate the predictive value of serum vascular endothelial growth factor (VEGF), squamous cell carcinoma-associated antigen (SCCAg) and miRNA let-7a in lymph node metastasis and postoperative recurrence in patients with laryngeal cancer.Methods:A total of 82 patients with laryngeal cancer in the Second Central Hospital of Baoding from November 2017 to October 2019 were selected as the research subjects, including 18 cases of lymph node metastasis (metastasis group) and 64 cases of non metastasis (non metastasis group). The blood routine was tested before operation, and the baseline data, serum VEGF, SCCAg and miRNA let-7a levels were compared between the two groups. Logistic regression was used to analyze the related influencing factors of lymph node metastasis in patients with laryngeal cancer. The correlation between serum VEGF, SCCAg, miRNA let-7a levels and clinicopathological characteristics was analyzed. The receiver operating characteristic (ROC)curve was used to analyze the value of each index and the combined diagnosis of lymph node metastasis in patients with laryngeal cancer. After 1 year of follow-up, the serum VEGF, SCCAg and miRNA let-7a levels of patients with or without recurrent laryngeal cancer were compared. ROC curve was used to evaluate the value of VEGF, SCCAg, and miRNA let-7a in predicting the recurrence of laryngeal cancer.Results:There were statistically significant differences in tumor node metastasis (TNM) stage, degree of infiltration, degree of differentiation, serum VEGF, SCCAg, and miRNA let-7a levels between the metastasis group and non metastasis group (all P<0.05). Serum VEGF, SCCAg, miRNA let-7a levels in patients with laryngeal cancer were related to TNM stage, degree of infiltration and degree of differentiation (all P<0.05). The combined diagnosis of serum VEGF, SCCAg and miRNA let-7a levels in the diagnosis of lymph node metastasis in patients with laryngeal cancer showed that the diagnostic sensitivity and specificity were 88.89% and 70.31%, respectively. The serum VEGF and SCCAg levels of patients with recurrence after operation were higher than those without recurrence, and the level of miRNA let-7a was lower than those without recurrence (all P<0.05). The sensitivity and specificity of combined serum VEGF, SCCAg and miRNA LET-7a levels in predicting postoperative recurrence of laryngeal cancer were 72.97% and 91.11%, respectively. Conclusions:VEGF, SCCAg, miRNA let-7a in patients with laryngeal cancer have a certain correlation with clinicopathological characteristics, which can assist in the diagnosis of lymph node metastasis and help clinical prediction of postoperative recurrence in patients with laryngeal cancer, and provide a reference for the formulation of clinical treatment plans.

Objective:Based on the clinical indicators of severe community-acquired pneumonia in emergency department, the early warning indicators of critical condition were constructed.Methods:The general information, vital signs before entering ICU, laboratory indexes and the survival rate in 30 days of 118 patients with community-acquired pneumonia were retrospectively collected in the emergency care unit of Peking Union Medical College Hospital from January to December 2018. The indexes of death patients (24 cases) and alive patients (98 cases) underwent comparative analysis, using ROC curve to predict the clinical outcome and reliable parameters of emergency patients with community-acquired pneumonia. The best cutoff value was determined according to Youden index and then undergoing multiple factors Logistic stepwise regression analysis. Then early warning model of critical degree was finally built.Results:Eleven indicators were used to predict the criticality of patients with acute community-acquired pneumonia, including AVPU (alert, voice, pain, unresponsive) score, Glasgow Coma Scale(GCS), heart rate, pulse oxygen saturation (SpO 2), fraction of inspiration O 2, oxygenation index,potential of hydrogen, blood potassium (K +), bilirubin, urea nitrogen, and C reactive protein, the optimal cutoff values were 2 points, 8 points, 91 times per minute, 0.94, 41%, 81.20%, 7.38, 4.0 mmol/L, 10.90 μmol/L, 2.23 mmol/L, and 41.5 mg/L. Multiple Logistic stepwise regression showed that the independent factors for predicting death were GCS score, SpO 2 and urea nitrogen, and the predictive ability of the early-warning model was 83.7%. Conclusions:GCS score, SpO 2 and urea nitrogen are effective early warning indicators for the severity of severe community-acquired pneumonia in emergency department, which are conducive to the rapid and efficient early identification and treatment of critically ill patients. Therefore, they are worthy of promotion and application in clinical practice.

Objective:To investigate the clinical efficacy of anterior approach combined with blocking plates and screws in the management of acetabular fracture involving the quadrilateral area.Methods:A retrospective case series analysis was performed for 16 patients with acetabular fracture involving the quadrilateral area admitted to First and Second Affiliated Hospital of Guangxi Medical University from January 2017 to January 2019. There were 12 males and 4 females，with the age of 21-66 years［（45.3±10.6）years］. According to Letournel-Judet classification，there were 9 patients with bi-column fracture，6 with anterior and posterior traverse fracture and 1 with anterior column fracture. A total of 9 patients were operated via the ilioinguinal approach and 7 via the lateral-rectus approach. Reduction and fixation of the pelvis and acetabulum were performed，using 3.5 mm cortical bone screws or plates to block the internal displacement of fracture in the quadrilateral body. The incision length，operation time and intraoperative blood loss were recorded. The quality of fracture reduction was assessed according to the Matta reduction criteria at postoperative 2 days and hip function by the modified Merle D'Aubigne-Postel score at postoperative 3 months and 12 months. Postoperative complications were observed.Results:All patients were followed up for 13-24 months［（16.1±2.9）months］. The ilioinguinal approach and lateral-rectus approach showed surgical incision of 12-26 cm［（18.6±4.0）cm］and 8-15 cm［（10.7±2.3）cm］，respectively. The operation time was 107-215 minutes［（159.2±27.8）minutes］and the intraoperative blood loss was 200-2，300 ml［（853.1±489.7）ml］. According to Matta reduction criteria，the results were excellent in 9 patients and good in 7. Three months after operation，the modified Merle D'Aubigne-Postel score was 11-18 points［（15.2±2.2）points］，which showed the results were excellent in 4 patients，good in 7，fair in 4 and poor in 1，with the excellent and good rate of 69%. Twelve months after operation，the modified Merle D'Aubigne-Postel score was 13-18 points［（16.9±1.4）points］，which showed the results were excellent in 7 patients，good in 8 and fair in 1，with the excellent and good rate of 94%. The liquefaction of post-surgical incision was seen in a patient，bladder injury in a patient，lateral femoral cutaneous nerve injury in a patient，and heterotopic ossification in a patient. There was no loosening or breakage of the internal fixation.Conclusion:For acetabular fracture involving the quadrilateral area，anterior approach combined with blocking plates and screws can prevent the displacement of quadrilateral fracture and attain satisfactory reductiongood hip function recovery and few complications.

Objective:To investigate the changes of plasma high density lipoprotein cholesterol (HDL-C) and metabolic indicators in obese patients after laparoscopic sleeve gastrectomy (LSG).Methods:The retrospective cohort study was conducted. The clinical data of 69 obese patients who were admitted to the Tenth People′s Hospital of Tongji University from August 2013 to March 2017 were collected. There were 32 males and 37 females, aged (33±12)years, with a range from 18 to 65 years. Of 69 patients, 44 patients with preoperative HDL-C concentration <1.04 mmoL/L were allocated as low HDL-C group, and 25 patients with preoperative HDL-C concentration ≥1.04 mmoL/L were allocated as normal HDL-C group. Sixty-nine patients underwent LSG. Observation indicators: (1) analysis between preoperative HDL-C and clinical indicators; (2) follow-up; (3) stratified analysis of plasma HDL-C. Follow-up was conducted using outpatient examination and hospitalization review to detect changes of plasma HDL-C, insulin resistance index, uric acid, free fatty acids and body mass every 3 months after operation up to September 2017. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M ( P25, P75), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Pearson correlation coefficient was used to analyze measurement data with normal distribution, and Spearman correlation was used to analyze measurement data with skewed distribution. Repeated measurement data were analyzed by ANOVA.

Objective:To evaluate the safety and feasibility of intranodal lymphangiography combined thoracic duct embolization in the treatment of chylous leakage.Methods:The clinical data of ten patients with chylous leakage from July to December 2019 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. There were 6 cases of chylothorax, 1 case of chylous ascites, and 3 cases of chylothorax combined with chylous ascites, respectively. Conservative treatment was invalid in all cases. The locations of cisterna chyli and thoracic duct were defined by percutaneous puncture intranodal lymphangiography. Then the percutaneous transabdominal puncture of cisterna chyli was performed and the microcatheter was inducted. The location of fistula was visualized by thoracic duct lymphangiography, and the embolization was performed by microcoils combined tissue adhesive agents. The post-operative curative effect and complications were recorded.Results:One patient did not receive thoracic duct embolization because it was failed to visualize cisterna chyli by intranodal lymphatic angiography; thoracic duct embolization was successfully performed in the other 9 patients after chylous leakage fistula was located. Percutaneous transabdominal puncture of cisterna chyli was successfully accomplished in 8 patients. As for the other patient, after repeated failure of puncture, fluoroscopy-guided retrograde puncture at the proximal thoracic duct was performed successfully. After the operation, the drain output was completely disappeared within 3 to 7 days in 8 patients, and decreased down to 120 ml/d in 1 patient. Mild abdominal hemorrhage was found in 1 patient after thoracic duct embolization, without any treatment. No serious complications was found in all cases.Conclusion:Intranodal lymphangiography and thoracic catheter embolization is safe and effective in the treatment of chylous leakage, with a low complication rate.

OBJECTIVETo assess the effects of laparoscopic sleeve gastrectomy (LSG) on insulin secretion mode and metabolism of glucose and lipid in morbidly obese patients.

METHODSClinical data of 65 morbidly obese patients [body mass index (BMI) ≥30 kg/m] undergoing LSG at Shanghai 10th People's Hospital from August 2012 to December 2016 were retrospectively analyzed. According to the result of OGTT, these obese patients were divided into three groups: normal glucose tolerance (NGT, 23 cases), impaired glucose tolerance (IGT, 22 cases) and type 2 diabetes mellitus (DM, 20 cases) groups. Twenty-two healthy people [BMI (23.1±1.4) kg/m] were used as control group. The anthropometries parameters [weight, BMI, waist circumference, body fat percentage, excess weight loss(%EWL)], glucose metabolic indices [fasting plasma glucose (FPG), fasting insulin (FINS), glycosylated hemoglobin (HbA1c), homeostasis model assessment-insulin resistance index (HOMA-IR)], lipid profile (TC, TG, HDL-C, LDL-C) and inflammatory factor (UA, TNF-α) of 3 groups were detected before operation and at postoperative 1-, 3-, 6-month. These variables were analyzed among morbidly obese groups before and after surgery and compared to control group. Clinical registration number of this study was ChiCTROCSl2002381.

RESULTSBody weight, waist circumference and BMI of morbidly obese patients all decreased at postoperative 1-, 3-, 6-month. Postoperative %EWL increased obviously to (71.5±24.7)% with the highest range in DM group. Percentage of successful weight loss (%EWL>50%) in NGT, IGT and DM groups was 63.6%, 83.9% and 90.0% at postoperative 6-month respectively, and DM group was also the highest. At postoperative 6-month, HbA1c of 3 morbidly obese groups became normal; FPG and postprandial 2-hour glucose of IGT and DM group decreased to normal level; insulin level of 3 morbidly obese groups decreased obviously compared to pre-operation (all P<0.05), especially FINS and postprandial 2-hour insulin became normal without significant difference of control group (P>0.05), while postprandial 30-minute and 60-minute insulin levels in 3 groups were still higher as compared to control group. The insulin secretion curves of morbidly obese groups showed hyperinsulinemia before surgery. The peak of insulin secretion curve in IGT and DM group moved back to postprandial 120-minute before operation, and returned to 60-minute after operation, with basic normal rhythm of secretion curve. Preoperative HOMA-IR in all 3 morbidly obese groups was higher than that in control group (all P<0.05) and remarkably lower at postoperative 6-month compared to pre-operation(P<0.05). In 3 morbidly obese groups after operation, TG decreased, HDL-C increased, UA and TNF-α decreased significantly compared to before operation (all P<0.05). At postoperative 6-month, the HOMA-IR of DM group was positively correlated with BMI (r=0.236, P=0.004) and TNF-α (r=0.228, P=0.033), and was not correlated with HDL-C(P>0.05).

CONCLUSIONSLSG can effectively ameliorate hyperinsulinemia and insulin secretion curve, and improve metabolic disorder and insulin resistance of different stage in obesity patients with glucose metabolic disorder. Insulin resistance is correlated with body weight and inflammatory factors.
