Most of the existing near-infrared noninvasive blood glucose detection models focus on the relationship between near-infrared absorbance and blood glucose concentration, but do not consider the impact of human physiological state on blood glucose concentration. In order to improve the performance of prediction model, particle swarm optimization (PSO) algorithm was used to train the structure paramters of back propagation (BP) neural network. Moreover, systolic blood pressure, pulse rate, body temperature and 1 550 nm absorbance were introduced as input variables of blood glucose concentration prediction model, and BP neural network was used as prediction model. In order to solve the problem that traditional BP neural network is easy to fall into local optimization, a hybrid model based on PSO-BP was introduced in this paper. The results showed that the prediction effect of PSO-BP model was better than that of traditional BP neural network. The prediction root mean square error and correlation coefficient of ten-fold cross-validation were 0.95 mmol/L and 0.74, respectively. The Clarke error grid analysis results showed that the proportion of model prediction results falling into region A was 84.39%, and the proportion falling into region B was 15.61%, which met the clinical requirements. The model can quickly measure the blood glucose concentration of the subject, and has relatively high accuracy.

Objective To systematically evaluate the efficacy of adjuvant radiotherapy after thymoma resection. Methods The PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP, CNKI databases were systematically searched to find relevant literature comparing the efficacy and effectiveness of thymoma resection and thymoma resection+postoperative radiation therapy (PORT) for treating thymoma published from inception to January 2024. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included retrospective studies, and Review Manager 5.4 software was used to perform meta-analysis. Results A total of 23 articles were included, all of which were retrospective studies. There were a total of 13742 patients, including 6980 patients in the simple surgery group, with 3321 males and 3659 females, and an average age of 54.08 years; 6762 patients in the surgery+PORT group, with 3385 males and 3377 females, and an average age of 53.76 years. The NOS scores of the included literature were all≥7 points. The results of the meta-analysis showed that compared with the simple surgery group, the surgery+PORT group had higher 1-year overall survival rate [OR=0.32, 95%CI (0.25, 0.42), P<0.001], 3-year overall survival rate [OR=0.55, 95%CI (0.48, 0.64), P<0.001], 5-year overall survival rate [OR=0.66, 95%CI (0.58, 0.75), P<0.001], 10-year overall survival rate [OR=0.71, 95%CI (0.57, 0.88), P=0.002], 1-year disease-free survival rate [OR=0.47, 95%CI (0.23, 0.93), P=0.030], 5-year disease-free survival rate [OR=0.61, 95%CI (0.45, 0.84), P=0.003], 3-year disease-specific survival rate [OR=0.44, 95%CI (0.35, 0.55), P<0.001], 5-year disease-specific survival rate [OR=0.53, 95%CI (0.44, 0.63), P<0.001] and 10-year disease-specific survival rate [OR=0.53, 95%CI (0.35, 0.82), P=0.004]. But there was no statistically significant difference between the two groups in terms of 3-year disease-free survival rate [OR=0.86, 95%CI (0.61, 1.22), P=0.400], 10-year disease-free survival rate [OR=0.70, 95%CI (0.47, 1.05), P=0.080] and 1-year disease-specific survival rate [OR=0.83, 95%CI (0.55, 1.26), P=0.380]. Conclusion PORT after thymoma resection has more advantages than simple surgical treatment in terms of 1-, 3-, 5-, and 10-year overall survival, 1- and 5-year disease-free survival, and 3-, 5- and 10-year disease-specific survival.

OBJECTIVE: To compare the effectiveness of TiRobot-assisted and C-arm X-ray fluoroscopy assisted percutaneous kyphoplasty (PKP) via pedicle of vertebra in the treatment of osteoporotic vertebral compression fracture (OVCF) of thoracic vertebrae. METHODS: The clinical data of 85 patients with OVCF of thoracic vertebrae who were admitted between January 2020 and March 2023 and met the selection criteria was retrospectively analyzed including 40 patients (50 vertebrae) undergoing PKP assisted by TiRobot (group A) and 45 patients (50 vertebrae) undergoing PKP assisted by C-arm X-ray fluoroscopy (group B). There was no significant difference in the comparison of baseline data such as gender, age, body mass index, bone mineral density T-value, fracture segment, trauma history, and preoperative numerical rating scale (NRS) score, Oswestry disability index (ODI), and Cobb angle of injured vertebra between the two groups ( P>0.05). The effectiveness evaluation indexes of the two groups, including the operation time, the volume of injected cement, the times of fluoroscopies, the length of hospital stay, and the occurrence of postoperative complications were collected and compared. Anteroposterior and lateral X-ray films and CT of the injured vertebra were reviewed at 1 day after operation to observe whether there was cement leakage and to evaluate the distribution of cement in the injured vertebra. Before and after operation, pain was assessed using the NRS score, dysfunction was assessed using the ODI, and vertebral height recovery was assessed by measuring the Cobb angle of the injured vertebrae by X-ray films. RESULTS: Both groups of patients successfully completed the operation, the operation time, the volume of injected cement, the times of fluoroscopies, and the length of hospital stay in group A were significantly less than those in group B ( P<0.05). The patients in two groups were followed up 4-12 months (mean, 9.6 months). Bone cement leakage occurred in 5 vertebrae in group A and 15 vertebrae in group B after operation, all of which leaked to the intervertebral space and around the vertebral body, and the patients had no obvious clinical symptoms. The difference of bone cement leakage between the two groups was significant ( P<0.05). No severe complication such as intraspinal leakage, infection, or vascular embolism was found in the two groups. At 1 day after operation, the distribution index of bone cement in group A was mostly grade Ⅴ, which was well dispersed; while in group B, it was mostly grade Ⅱ and grade Ⅴ; the difference of bone cement distribution index between the two groups was significant ( P<0.05). The NRS score, ODI, and Cobb angle of injured vertebra in both groups were significantly improved at 1 day after operation when compared with preoperative ones ( P<0.05). There was no significant difference in the difference of the above indexes between the two groups before and after operation ( P>0.05). CONCLUSION TiRobot-assisted unilateral PKP in the treatment of OVCF of thoracic vertebrae is safe and effective, which can reduce the X-ray transmission times during operation, shorten the operation time, reduce the volume of bone cement injection, and thus decrease incidence of bone cement leakage.

Objective To investigate the significance of interleukin-13 (IL-13) in patients with active lupus nephritis (LN). Methods Ten healthy volunteers and 16 patients with active LN were included in this study. The protein level of IL-13 in plasma was examined by enzyme linked immunosorbent assay (ELISA), and gene expression of IL-13 in peripheral blood mononuclear cells (PBMCs) by reverse transcription polymerase chain reaction (RT-PCR). Expression of IL-13 mRNA in renal tissue was studied by in situ hybridization (ISH) techniques. Results The level of IL-13 in plasma and the expression of IL-13 mRNA in PBMCs were significantly higher in LN patients than those in the controls ( P ＜ 0.001 ). Increased expression of IL-13 mRNA was detected in renal tissue of active LN patients compared to those in the controls ( P ＜ 0.001 ). Analysis of the linear correlation indicated that the level of IL-13 mRNA in the tubulointerstitial area in patients with active LN correlated with the concentration of serum creatinine (Scr), the glomerular activity index (GAl), the activity index of tubulointerstitium, and the level of serum C3 ( P ＜ 0.05 for each). Conclusion The elevation of IL-13 may play an important role inthe molecular pathogenesis of active LN.

The diagnosis of hypertrophic cardiomyopathy (HCM) is of great significance for the early risk classification of sudden cardiac death and the screening of family genetic diseases. This research proposed a HCM automatic detection method based on convolution neural network (CNN) model, using single-lead electrocardiogram (ECG) signal as the research object. Firstly, the R-wave peak locations of single-lead ECG signal were determined, followed by the ECG signal segmentation and resample in units of heart beats, then a CNN model was built to automatically extract the deep features in the ECG signal and perform automatic classification and HCM detection. The experimental data is derived from 108 ECG records extracted from three public databases provided by PhysioNet, the database established in this research consists of 14,459 heartbeats, and each heartbeat contains 128 sampling points. The results revealed that the optimized CNN model could effectively detect HCM, the accuracy, sensitivity and specificity were 95.98%, 98.03% and 95.79% respectively. In this research, the deep learning method was introduced for the analysis of single-lead ECG of HCM patients, which could not only overcome the technical limitations of conventional detection methods based on multi-lead ECG, but also has important application value for assisting doctor in fast and convenient large-scale HCM preliminary screening.

Objective     To identify the preoperative risk factors for prolonged mechanical ventilation (PMV) after pulmonary thromboendarterectomy (PTE). Methods    The clinical data of patients who underwent PTE from December 2016 to August 2021 in our hospital were retrospectively analyzed. The patients were divided into two groups according to the postoperative mechanical ventilation time, including a postoperative mechanical ventilation time≤48 h group (≤48 h group) and a postoperative mechanical ventilation time>48 h (PMV) group (>48 h group). Univariable and logistic regression analysis were used to identify the preoperative risk factors for postoperative PMV. Results    Totally, 90 patients were enrolled in this study. There were 40 patients in the ≤48 h group, including 30 males and 10 females, with a mean age of 45.48±12.72 years, and there were 50 patients in the >48 h group, including 29 males and 21 females, with a mean age of 55.50±10.42 years. The results showed that in the ≤48 h group, the median postoperative ICU stay was 3.0 days, and the median postoperative hospital stay was 15.0 days; in the >48 h group, the median postoperative ICU stay was 7.0 days, and the median postoperative hospital stay was 20.0 days. The postoperative PMV was significantly correlated with tricuspid annular plane systolic excursion (TAPSE) [OR=0.839, 95%CI (0.716, 0.983), P=0.030], age [OR=1.082, 95%CI (1.034, 1.132), P=0.001] and pulmonary vascular resistance (PVR) [OR=1.001, 95%CI (1.000, 1.003), P=0.028]. Conclusion    Age and PVR are the preoperative risk factors for PMV after PTE, and TAPSE is the preoperative protective factor for PMV after PTE.
