Objective To investigate the clinical distribution and risk factors of metabolic syndrome(MS)in children from Lubei district of Tangshan City from 2020 to 2024.Methods A total of 964 children were identified by multi-segment stratified cluster sampling.A questionnaire survey was conducted on all subjects,and the recovery rate of the questionnaire was 98.0%,with 945 samples recovered.The detection rates of MS in different populations were compared,and risk factors of MS in children were analysed by Logistic regression analysis.Results In 945 children,49(5.19%)had MS,and there was no significant difference in detection rate between different genders of children(P>0.05).There were no significant differences in blood pressure[systolic blood pressure(SBP)and diastolic blood pressure(DBP)],blood lipid[triglycerides(TG)and high density lipoprotein cholesterol(HDL-C)]between children ages 7 to 10 years old and 11 to 14 years old(P>0.05).The values of total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C)and waist circumference(WC)were higher in boys aged 11-14 than those in girls(P＜0.05).The proportion of body weight and obesity,the proportion of physical activity time＜10 h/week,the proportion of family history of hypertension and WC level were higher in the MS group than those in the non-MS group(P＜0.05).Multivariate Logistic regression model showed that weight obesity,physical activity time＜10 h/week,family history of hypertension and high WC value were independent risk factors for MS in children(P＜0.05).Conclusion Obesity,family history of hypertension,time spent in physical activity and higher WC are strongly associated with the development of MS in children,and clinical attention should be paid to them.

Objective:To investigate the efficacy and safety of bendamustine combined with anti-CD20 monoclonal antibody in the first-line treatment of older patients with indolent B-cell non-Hodgkin lymphoma (B-iNHL) .Methods:The clinical data of 159 patients with B-iNHL enrolled in 16 hospitals from Jiangsu Cooperative Lymphoma Group from December 1, 2019, to April 20, 2024, were analyzed for regimen efficacy and safety. Bendamustine plus rituximab (BR) and bendamustine plus obinutuzumab (BG) were administered to 139 (87.4% ) and 20 (12.6% ) patients, respectively.Results:Among the 159 patients, 101 (63.5% ) were male and 58 (36.5% ) were female, with a median age of 69 years (range: 60–84). Efficacy could be assessed in 138 (86.8% ) patients. The efficacy assessment demonstrated that the overall response rate was 92.0% with complete and partial remissions in 75 (54.3% ) and 52 (37.7% ) cases, respectively. With a median follow-up of 24 months (range: 4–64), the progression-free survival rate was (87.5 ± 3.0) % and the overall survival rate was (83.2 ± 3.3) %. Of the 27 patients who died, 6 (22.2% ) died due to disease progression. The mean applied dose of bendamustine per cycle was 73.0 (50.8–89.7) mg/m 2 per day, administered on days 1 and 2. Adverse events of grade 3 or higher were reported in 53 (33.3% ) patients, with infection (30 cases,18.9% ) and neutropenia (24 cases, 15.1% ) demonstrating the highest incidence. Conclusion:Bendamustine combined with anti-CD20 monoclonal antibody demonstrated good efficacy and is well-tolerated in the first-line treatment of elderly patients with B-iNHL.

Objective:To compare the precision and stability of handheld full-course visual navigation and robot-assisted total hip arthroplasty (THA), as well as to evaluate perioperative laboratory indicators and clinical efficacy.Methods:A retrospective analysis was performed on 68 patients with unilateral hip joint disorders who underwent primary THA at the General Hospital of the People's Liberation Army of China from January to June 2024. Patients were divided into two groups based on the assistance method: the Visual Treatment Solution (VTS) group, which included 34 patients (13 males, 21 females; mean age 56.92±8.31 years; body mass index[BMI] 24.20±3.55 kg/m 2), and the MAKO group, also with 34 patients (18 males, 16 females; mean age 57.97±6.54 years; BMI 25.20±3.91 kg/m 2). Among the VTS group, 1 there were 18 cases on the left side and 16 cases on the right side, including 14 cases of femoral head necrosis, 8 cases of congenital hip dysplasia, and 12 cases of hip osteoarthritis. In the MAKO group, there were 19 cases on the left side and 15 cases on the right side, including 13 cases of femoral head necrosis, 10 cases of congenital hip dysplasia, and 11 cases of hip osteoarthritis. Preoperative planning, intraoperative verification deviations, postoperative acetabular prosthesis anteversion and abduction angles, and limb length discrepancies were analyzed. Acetabular angle distribution scatter plots were generated for intraoperative verification and postoperative imaging. The operation time, hospital stay, and laboratory values, including hemoglobin (Hb) loss, fibrinogen degradation products (FDP), D-dimer, high-sensitivity C-reactive protein (hCRP), as well as postoperative pain (measured by the visual analogue scale, VAS), hip Harris score (HHS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were recorded. Results:No statistically significant differences were observed between postoperative imaging measurements of anteversion and abduction angles and intraoperative verification values ( P>0.05). Postoperative imaging indicated that 91% (31/34) of the VTS group and 100% (34/34) of the MAKO group were within the Lewinnek safety zone. The scatter distribution of angles in the MAKO group was more concentrated than that in the VTS group. Furthermore, the angle deviation between intraoperative verification and preoperative planning was significantly greater in the VTS group for both anteversion (2.00° [-1.00°, 4.00°] vs. 0.00° [-1.00°, 1.00°]) and abduction angles (-1.00° [-5.00°, 0.00°] vs. 0.00° [-1.00°, 1.00°]; P<0.05). The bilateral limb length discrepancies were 1.35(0.67, 2.45) mm in the VTS group and 1.65(0.50, 2.52) mm in the MAKO group, with no significant difference noted ( P>0.05). Both methods achieved effective hip biomechanical reconstruction. Additionally, no significant differences in operation time, Hb loss, FDP, D-dimer, hCRP, or postoperative hospital stay were found ( P>0.05). Follow-up at one and three months postoperatively showed no significant differences in VAS (2.94±0.92 vs. 2.97±0.83), HHS (69.88±4.20 vs. 70.06±3.88), or WOMAC scores (22.44±3.15 vs. 22.76±3.39) between the two groups ( P>0.05). Conclusion:The stability of preoperative planning and design in robot-assisted total hip arthroplasty is superior to that of handheld navigation methods. Nevertheless, both approaches demonstrate comparable postoperative prosthesis stability, laboratory indicators, and clinical outcomes.

Objective:To investigate the accurate diagnosis and differential diagnosis of non-primary solid malignant tumors in breast needle core biopsy.Methods:Twenty-three cases of breast, axilla or neck lymph nodes pathologically diagnosed as non-primary solid malignant tumors were collected at the First Affiliated Hospital of Nanjing Medical University, Nanjing, China from January 2013 to March 2023. The differential diagnoses and diagnostic features were analyzed, based on combining clinical data, histology, and expression characteristics of biomarkers.Results:All patients were female, with age ranging from 29 to 75 years (average 56 years). The average time from the diagnosis of primary tumor to the current diagnosis was 21 months (0 to 204 months).The primary sites included the ovary (9 cases), the lung (5 cases), the gastrointestinal tract (4 cases), the pancreas, intrahepatic bile duct, thyroid gland, nasal cavity and forearm skin (1 case each). No carcinoma in situ was found in any of the cases. The morphological differences were significant among the tumors, but similar to the primary tumors. The tumors of neuroendocrine and female reproductive tract had great morphological and immunophenotypic overlaps with breast cancer. Metastatic lung cancer cells showed obvious atypia and tumor giant cells. The morphology and immunophenotype of metastatic serous carcinoma of female reproductive system might resemble invasive micropapillary carcinoma of the breast. Metastatic adenocarcinoma of the gastrointestinal tract often had features of mucous secretion. Metastatic neuroendocrine tumors were bland in appearance and morphologically similar to solid papillary carcinoma of breast, but negative for ER. TRPS1 was mostly negative (18/23) and variably positive in ovarian (4/9) and intrahepatic bile duct (1/1) tumors.Conclusions:The diagnosis of breast needle core biopsy specimen should be combined with clinical history, imaging study, and careful examination of histological features, such as presence of in situ component, morphological similarity between the primary and metastatic tumors, and using appropriate markers to differentiate the primary from metastatic tumors.

Objective To investigate the effect of lidocaine on the chemotherapy sensitivity of gastric cancer cells by regulating the Wnt/β-catenin axis. Methods Human gastric cancer cells SGC-7901 in logarithmic growth phase were inoculated into 96-well plates and treated with different concentrations of lidocaine (0, 10, 50, 100, 150, 200 μmol/L) for 24 h. The cell viability at different concentrations was compared. The SGC-7901 cells in logarithmic growth phase were divided into control group, cisplatin group, low concentration lidocaine group (Lido-L group), medium concentration lidocaine group (Lido-M group), high concentration lidocaine group (Lido-H group), high concentration lidocaine + Wnt/β-catenin signal pathway activator SKL2001 group (Lido-H+SKL2001 group). The cell proliferation, invasion, and migration abilities of each group were compared by 5-acetylidene-2'deoxyuracil nucleoside (EdU) cell proliferation detection, Transwell assay, and scratch healing experiment. The apoptosis of each group was detected by TUNEL assay. The expressions of apoptosis, epithelial-mesenchymal transition, and Wnt/β-catenin pathway-related proteins in each group were detected. Results Compared with 0 μmol/L lidocaine, the cell viability of SGC-7901 cells treated with 50, 100, 150, and 200 μmol/L lidocaine was reduced (P < 0.05). Compared with the control group, the EdU positive rate, the number of cell invasion, scratch healing rate, and expressions of vimentin, N-cadherin, B-cell lymphoma-associated protein-2 (Bcl-2), cyclin D1, scattered protein 2 (DVL2), Wnt family member 3a (Wnt3a), β-catenin (β-catenin) were reduced in the cisplatin group, while the cell apoptosis rate was increased, the expressions of E-cadherin, B-cell lymphoma-2-associated X protein (Bax), Cleaved-caspase-3 were increased, and the differences were statistically significant (P < 0.05). Compared with the cisplatin group, the EdU positive rate, the number of cell invasion, scratch healing rate, and expressions of vimentin, N-cadherin, Bcl-2, cyclin Dl, DVL2, Wnt3a, β-catenin were gradually reduced in the Lido-L group, Lido-M group, and Lido-H group, while the cell apoptosis rate, the expressions of E-cadherin, B-cell lymphoma-2-associated X protein (Bax), Cleaved-caspase-3 were increased (P < 0.05). Compared with the Lido-H group, the EdU positive rate, the number of cell invasion, scratch healing rate, and expressions of vimentin, N-cadherin, Bcl-2, cyclin Dl, DVL2, Wnt3a, β-catenin were increased in the Lido-H+SKL2001 group, while the cell apoptosis rate and expressions of E-cadherin, Bax, Cleaved-caspase-3 were reduced, the differences were statistically significant (P < 0.05). Conclusion Lidocaine may enhance the chemotherapy sensitivity of gastric cancer cells by inhibiting the activation of the Wnt/β-catenin axis.

INTRODUCTION: Contrast-induced nephropathy (CIN) is a serious complication of percutaneous coronary intervention (PCI). The most important predictor of CIN is renal function before PCI. Serum creatinine (SCr) is a commonly used biomarker of renal function, but an elevation in SCr lags behind the onset of kidney injury and is not viable for early detection of CIN after PCI. Our primary objective was to investigate whether preoperative cystatin C (CysC) before PCI was an early predictor of postoperative CIN. The secondary objective was to evaluate associations between preoperative CysC and renal biomarkers. METHODS: From December 2014 to December 2015, 341 patients with normal renal function were enrolled into the study at our medical centre. All patients were apportioned to normal CysC (≤1.03 mg/L) or high CysC (>1.03 mg/L) groups before PCI and were hydrated from four hours prior to PCI to 24 hours after it. Renal function was monitored at 48 hours after PCI. Clinical parameters were recorded before and after PCI. RESULTS: There was no significant difference in preoperative SCr between the CIN and non-CIN groups. However, preoperative CysC demonstrated significant difference between the two groups (p <0.01). Logistic regression analysis showed that elevated CysC before PCI was a risk factor for CIN (p = 0.013). Furthermore, the linear regression models identified an association between CysC before PCI and renal function after PCI. CONCLUSION CysC before PCI was viable as a biomarker of renal function after PCI and high preoperative CysC was able to predict CIN earlier than SCr.

Objective:To explore the pros and cons of sequential high-flow nasal cannula (HFNC) and non-invasive positive pressure ventilation (NIPPV) immediately following early extubated patients with severe respiratory failure (SRF) due to acute exacerbations of chronic obstructive pulmonary disease (AECOPD), so as to provide evidence for clinical selection of optimal scheme.Methods:Consecutive AECOPD patients admitted to the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University from January 2019 to September 2020 were screened for enrollment. Patients were between 40 years old and 85 years old with acute exacerbation of bronchial-pulmonary infection, who received endotracheal intubation mechanical ventilation (ETI-MV) as the initial respiratory support method. The pattern of synchronous intermittent mandatory ventilation (SIMV) was used in the study. The parameters were set as follows: tidal volume (VT) 8 mL/kg, support pressure 10-15 cmH 2O (1 cmH 2O = 0.098 kPa), positive end-expiratory pressure (PEEP) 4-6 cmH 2O and the ratio of inspiratory to expiratory time 1.5-2.5∶1. Under these conditions, the plateau pressure (Pplat) was maintained less than 30 cmH 2O. The minimum fraction of inspired oxygen was adjusted to keep the pulse oxygen saturation no less than 0.92. When the pulmonary infection control window (PIC window) occurred, the subjects were extubated immediately and randomly divided into two groups, with one group receiving HFNC (called HFNC group), the other group receiving NIPPV (called NIPPV group). Patients with failed sequential HFNC or NIPPV underwent tracheal re-intubation. The rate of tracheal re-intubation within 7 days of extubation, complications (such as nose and face crush injury and gastric distension), in-hospital mortality, duration of ETI before PIC window, length of RICU stay and length of hospital stay were compared, respectively. Results:Forty-four patients were enrolled in the study, 20 in the HFNC group and 24 in the NIPPV group. There was no significant difference in the duration of ETI before PIC window between HFNC and NIPPV groups (hours: 95.9±13.1 vs. 91.8±20.4, P > 0.05). The rate of tracheal re-intubation within 7 days in the HFNC group was significantly higher than that in the NIPPV group [35.0% (7/20) vs. 4.2 % (1/24), P < 0.05]. However, the incidence of complication in the HFNC group was significantly lower than that in the NIPPV group [0% (0/20) vs. 25.0% (6/24), P < 0.05]. Compared with the NIPPV group, the in-hospital mortality in the HFNC group was slightly higher [5.0% (1/20) vs. 4.2% (1/24)], the length of RICU stay (days: 19.5±10.8 vs. 15.5±7.2) and the length of hospital stay (days: 27.4±12.2 vs. 23.3±10.9) were slightly longer, without statistical differences (all P > 0.05). Conclusion:For early extubated patients with SRF due to AECOPD, the compliance of sequential HFNC increased and the complications decreased significantly, but the final effect may be worse than sequential NIPPV.

With continually improving reperfusion strategies and patient care, the overall mortality of acute myocardial infarction (AMI) has been significantly reduced during the past two decades. However, this success is a double-edged sword, as many patients surviving an AMI will progress towards ischemic heart failure (HF) over time. The pathologic causes of ischemic HF are undoubtedly multifactorial. However, the inflammatory response is considered one of the most important causes of pathological remodeling because it spans the whole process of HF development. The macrophage-mediated inflammatory response was once considered a purely harmful factor leading to pathological remodeling and HF. However, growing evidence demonstrates that multiple subgroups of macrophage exist and contribute differently to ischemic HF development. Understanding macrophage populations and how they contribute to post-MI remodeling and consequent ischemic HF is, therefore, critical to understanding and treating the disease. This review focuses on different macrophage populations that regulate post-MI cardiac injury and how immunoregulation therapy may benefit patients with ischemic HF.
