ABSTRACT
Objective:To explore the correlation between the triglyceride glucose (TyG) index and the risk of vitamin D deficiency (VDD) in patients with type 2 diabetes (T2DM).Methods:T2DM patients admitted to the Department of Geriatrics, the Second Xiangya Hospital of Central South University from February 2020 to February 2023 were included. We collected general clinical and biochemical data from patients and calculated the TyG index. Divide the study subjects into VDD group and control (CON) group based on serum 25 hydroxyvitamin D [25 hydroxyvitamin D, 25(OH)D] levels, and compare the general clinical characteristics between the two groups; Pearson rank correlation analysis was used to study the correlation between TyG index and 25(OH)D; According to the third percentile of the TyG index, the study subjects were divided into three groups (Q1, Q2, Q3), and logistic regression analysis was used to explore the association between the TyG index and the risk of VDD.Results:This study included 526 patients with T2DM, including 312 males and 214 females, aged 37 to 78 years old. There were 300 VDD patients, accounting for 57.03%, and 226 in the CON group. The TyG index of VDD patients was higher than that of the CON group ( P<0.05), and there was a negative correlation between the TyG index and serum 25(OH)D levels ( P<0.05). Logistic regression analysis showed that compared with the Q1 group, the risk of VDD in Q3 group patients was 2.892 times higher than that in Q1 group ( OR=2.892, 95% CI: 1.865-4.485, P<0.001). After adjusting for age, gender, smoking, obesity, insulin, oral hypoglycemic drugs, statin use, and blood biochemical indicators, the risk of illness in the Q3 group was 2.303 times higher than that in the Q1 group ( OR=2.303, 95% CI: 1.288-4.117, P=0.005). Conclusions:In T2DM patients, the TyG index is negatively correlated with serum 25 (OH) D levels. T2DM patients with high TyG index have an increased risk of VDD, and the TyG index can be used to observe the possibility of VDD occurrence, which is beneficial for early detection of VDD patients.
ABSTRACT
BACKGROUND@#Immunotherapies such as adoptive immune cell infusion and immune-modulating agents are widely used for cancer treatment, and the concomitant symptoms, including cytokine release syndrome (CRS) or immune-related adverse events (irAEs), are frequently reported. However, clinical manifestations induced by mismatched donor granulocyte colony-stimulating factor mobilized peripheral blood mononuclear cell (GPBMC) infusion in patients receiving microtransplant (MST) have not yet been well depicted.@*METHODS@#We analyzed 88 cycles of mismatched GPBMC infusion in patients with acute myeloid leukemia receiving MST and 54 cycles of chemotherapy without GPBMC infusion as a comparison. Clinical symptoms and their correlation with clinical features, laboratory findings, and clinical response were explored.@*RESULTS@#Fever (58.0% [51/88]) and chills (43.2% [38/88]) were the significant early-onset symptoms after GPBMC infusion. Patients possessing less human leukocyte antigen-matching loci with the donor or those with unrelated donors experienced more chills (3 [2-5] loci vs. 5 [3-5] loci, P = 0.043 and 66.7% [12/18] vs. 37.1% [26/70], P = 0.024). On the other hand, those with decreased CD4 + /CD8 + T-cell ratio developed more fever (0.8 [0.7-1.2] vs. 1.4 [1.1-2.2], P = 0.007). Multivariable analysis demonstrated that younger patients experienced more fever (odds ratio [OR] = 0.963, 95% confidence interval [CI]: 0.932-0.995, P = 0.022), while patients with younger donors experienced more chills (OR = 0.915, 95% CI: 0.859-0.975, P = 0.006). Elevated ultra-sensitive C-reactive protein levels in the absence of cytokine storm were observed following GPBMC infusion, which indicated mild and transient inflammatory response. Although no predictive value of infusion-related syndrome to leukemia burden change was found, the proportion of host pre-treatment activated T cells was positively correlated with leukemia control.@*CONCLUSIONS@#Mismatched GPBMC infusion in MST induced unique infusion-related symptoms and laboratory changes, which were associated with donor- or recipient-derived risk factors, with less safety and tolerance concerns than reported CRS or irAEs.

Objective:To investigate the therapeutic effect of robot-assisted percutaneous screw fixation in LC-II pelvic fractures.Methods:A total of 46 patients with Young-Burgess LC-II pelvic fractures, who underwent surgical treatment at Shanghai Tenth People's Hospital from December 2019 to June 2022, were retrospectively analyzed. Among them, 27 were male and 19 were female, with an average age of 39.78±15.11 years (range, 19-68 years). The causes of injury were traffic accidents (28 cases) and fall from height (18 cases); all the cases were Type B pelvic fractures according to the Tile classification. The patients were divided into two groups based on the surgical approach: the robot group (26 cases) treated by Tianji robot-assisted percutaneous screw fixation, and the actual screw group (20 cases) treated by minimally invasive internal fixation under fluoroscopic guidance. The surgical time, blood loss, number of guide wire adjustments, the success rate of initial screw placement, postoperative vertical and horizontal displacement, and postoperative pelvic fracture reduction quality (Matta score) were compared between the two groups. Visual analogue scale (VAS) was used to assess patients' pain levels before and one week after surgery, and the clinical efficacy was evaluated using the Majeed score at the final follow-up. The occurrence of complications such as infection, vascular and nerve injury, and screw breakage was all recorded during the follow-up.Results:All patients successfully underwent the surgery and were followed up for an average of 11.93±3.09 months (range, 5-15 months). A total of 84 percutaneous screws were applied in the 46 cases, with 47 screws in the robot group and 37 screws in the actual screw group. The surgical time and number of guide wire adjustments were 81.27±4.90 minutes and 0.58±0.76 times in the robot group, 102.95±8.73 minutes and 5.80±2.24 times in the actual screw group, with significant differences ( t=-10.68, P<0.001; t=-11.13, P<0.001). There was no significant difference between the two groups in terms of intraoperative blood loss and postoperative vertical and horizontal displacement ( P>0.05). The success rate of initial screw placement in the robot group was 98% (46/47, 44 excellent, 2 good, 1 poor), while in the actual screw group, it was 86% (32/37, 27 excellent, 5 good, 5 poor), with a significant difference (χ 2=4.05, P=0.044). The VAS scores at one week postoperatively were 3.38±1.20 in the robot group and 6.80±1.61 in the actual screw group, with a significant difference ( t=-8.25, P<0.001). The excellent rate of Matta score after surgery was 92% in the robot group and 85% in the actual screw group, and the Majeed scores at the final follow-up were 86.54±3.10 and 85.7±2.20 respectively, with no significant difference between the two groups ( P>0.05). All patients achieved primary healing; no complications such as infection or screw breakage occurred during the follow-up period. Conclusion:Robot-assisted percutaneous access screw fixation for LC-II pelvic fracture can achieve accurate reduction of pelvic fracture, and is characterized by short operative time, low radiation exposure, and high safety and accuracy.
ABSTRACT
The outbreak of corona virus disease (COVID-19) has raised concerns among dentists to develop strategies to prevent infection of dental equipment, materials, and patients during an epidemic period. Strategies following the National Laws and Standards of China and local standards of several provinces for controlling cross-infection and instituting protective measures for medical staff in dental clinics during an epidemic period are discussed. A proposal is put forth for dental clinics that will face similar situations in the future. Further research is warranted to address potential problems that will be encountered under such dire circumstances.
ABSTRACT
Electrocardiogram (ECG) signals are easily disturbed by internal and external noise, and its morphological characteristics show significant variations for different patients. Even for the same patient, its characteristics are variable under different temporal and physical conditions. Therefore, ECG signal detection and recognition for the heart disease real-time monitoring and diagnosis are still difficult. Based on this, a wavelet self-adaptive threshold denoising combined with deep residual convolutional neural network algorithm was proposed for multiclass arrhythmias recognition. ECG signal filtering was implemented using wavelet adaptive threshold technology. A 20-layer convolutional neural network (CNN) containing multiple residual blocks, namely deep residual convolutional neural network (DR-CNN), was designed for recognition of five types of arrhythmia signals. The DR-CNN constructed by residual block local neural network units alleviated the difficulty of deep network convergence, the difficulty in tuning and so on. It also overcame the degradation problem of the traditional CNN when the network depth was increasing. Furthermore, the batch normalization of each convolution layer improved its convergence. Following the recommendations of the Association for the Advancements of Medical Instrumentation (AAMI), experimental results based on 94 091 2-lead heart beats from the MIT-BIH arrhythmia benchmark database demonstrated that our proposed method achieved the average detection accuracy of 99.034 9%, 99.498 0% and 99.334 7% for multiclass classification, ventricular ectopic beat (Veb) and supra-Veb (Sveb) recognition, respectively. Using the same platform and database, experimental results showed that under the comparable network complexity, our proposed method significantly improved the recognition accuracy, sensitivity and specificity compared to the traditional deep learning networks, such as deep Multilayer Perceptron (MLP), CNN, etc. The DR-CNN algorithm improves the accuracy of the arrhythmia intelligent diagnosis. If it is combined with wearable equipment, internet of things and wireless communication technology, the prevention, monitoring and diagnosis of heart disease can be extended to out-of-hospital scenarios, such as families and nursing homes. Therefore, it will improve the cure rate, and effectively save the medical resources.

ABSTRACT
Objective To investigate the effect of statin therapy on pneumonia and stroke outcome after acute ischemic stroke.Methods The patients with pneumonia after acute ischemic stroke were enrolled retrospectively.The demographic and clinical data of the patients were collected,including whether using statins,the clinical features of pneumonia,the days of using antibiotics,and neutrophil count.They were divided into either a statin group or a control group according to whether they used statins or not.Stroke outcome was evaluated with the modified Rankin scale.Results A total of 53 patients with pneumonia after acute ischemic stroke were enrolled in the study,20 of them were in the statin group and 33 were in the control group.There were no significant differences in age and the proportions of male and complicated with hypertension,diabetes and coronary heart disease between the statin group and the control group (all P > 0.05).The cure rate,improvement rate,invalid rate and mortality in the statin group were 50.00%,35.00%,15.00% and 0.00%,respectively; and in the control group were 15.15%,39.40%,33.30% and 15.15%,respectively.There were significant differences (P =0.003).The days of temperature returning to normal (2.10 ± 3.29 d vs.4.61 ±3.54 d; P =0.002),pulmonary rales disappearing (3.60 ±2.46 d vs.7.67 ±4.09 d; t =-4.019,P =0.000)and using antibiotics (7.05 ± 3.13 d vs.9.73 ± 4.00 d; t =-2.562,P =0.013) in the statin group were significantly shorter than those in the control group,while there were no significant differences in the days of cough and sputum production retuming to normal between the 2 groups.The proportions of diabetes (20.83% vs.55.17% ;x2 =6.473,P =0.011),posterior circulation stroke (4.7% vs.27.59% ; P =0.031)and bilateral lung shadows (29.17% vs.55.17% ;x2 =5.705,P=0.017),as well as baseline National Stroke Association NIH Stroke Scale (NIHSS) score (4.00 ± 4.54 vs.10.66 ± 6.33; t =1.898,P =0.001) in a good outcome group were significantly lower than those in a poor outcome group.But there was no significant difference in the proportion of the patients treated with statins between the good outcome group and the poor outcome group (41.67% vs.34.48% ;x2 =0.288,P =0.591).Multivariate logistic regression analysis showed that diabetes (odds ratio [OR] 5.146,95% confidence interval [CI] 1.166-22.709; P =0.031) and baseline NIHSS score (OR 1.251,95% CI 1.080-1.449; P =0.003) were the independent risk factor for patient with poor outcomes.Conclusions Statins may promote the pneumonia recovery in patients with acute ischemic stroke; however,it has no effect on stroke outcome.
ABSTRACT
This study examined the expression of cell adhesion molecule 1 (CADM1) in pancreatic cancer and the possible mechanism. The expression of CADM1 was detected by immunohistochemistry in tissues of pancreatic cancer, pancreatitis, and normal pancreas. The plasmid pcDNA3.1-Hygro(+)/CADM1 was transfected into PANC-1 cells (a pancreatic cancer cell line). The expression of CADM1 in the transfected cells was determined by RT-PCR and Western blotting. Cell growth was measured by the MTT method and cell apoptosis by flow cytometry. The results showed that CADM1 was weakly expressed in tissues of pancreatic cancer in contrast to its high expression in normal pancreatic and pancreatitis tissues. The expression level of CADM in pancreatic caner was intensely correlated with the differentiation degree, lymph node metastasis and TNM stages. The growth of CADM1-transfected PANC-1 cells was significantly suppressed in vitro by a G1 cell cycle arrest and apoptosis occurrence. It was concluded that re-expression of CADM1 inhibits the growth of pancreatic cancer cells and induces their apoptosis in vitro. As a tumor suppressor gene, CADM1 plays an important role in the occurrence, progression and metastasis of pancreatic cancer.

Objective To investigate the expressions of PI3K, AKT and MRP protein in pancreatic carcinoma and to determine the clinicopathological significance and the correlation among three protein expressions. Methods The immunohistochemical method was used to detect the expressions of PI3K, AKT and MRP in forty three pancreatic carcinoma, nine chronic pancreatitis and eight normal pancreatic tissue samples. Results The positive expression rates of PI3K, AKT and MRP were 46.51%, 55.81% and 39.53%, respectively in pancreatic carcinoma, which were remarkably higher than those in normal pancreatic tissue and in chronic pancreatitis (P<0.01 and P<0.05, respectively). The aberrant expression of PI3K, AKT and MRP were associated with lymph node metastasis and TNM stages (P<0.05). The abnormal expression rate in both MRP and PI3K was 32.56%, the normal expression rate of both MRP and PI3K was 46.51%, and there was positive correlation between the expression of MRP and PI3K(r=0.581, P<0.01). The abnormal expression rate of both MRP and AKT was 32.56%, the normal expression rate was 37.21%, and there was a positive correlation between MRP and PI3K (r=0.432,P<0.05). The abnormal expression rate of both MRP and PI3K was 37.21%, the normal expression rate of both MRP and PI3K was 32.56%, there was also a positive correlation between MRP and PI3K (r=0.306,P<0.05). Conclusions The expressions of PI3K, AKT and MRP were up-regulated in pancreatic carcinoma. The expressions of PI3K and AKT may be related to the lymph node metastasis and TNM staging.
