ABSTRACT
BACKGROUND: Central post-stroke pain (CPSP) significantly interferes with the quality of life and psychological well-being of stroke patients. Non-invasive brain stimulation (NIBS) has attracted significant attention as an emerging method for treating patients with CPSP. OBJECTIVE: To compare the clinical efficacy of noninvasive brain stimulation on pain, and psychological status of patients with central post-stroke pain using meta-analysis. METHODS: A computerized search of multiple databases was performed for identification of randomized controlled trials involving NIBS-led treatment of CPSP patients. Two researchers worked independently on literature screening, data extraction, and quality assessment. Research was conducted from inception of the database until October 2023. RevMan 5.0 and Stata 15.0 software were used to conduct statistical analysis. RESULTS: Sixteen papers with 807 patients were finally included. The results showed that NIBS reduced patients' pain intensity [SMD = -0.39, 95% CI (-0.54, -0.24), p < 0.01] and was more effective in short-term CPSP patients. However, the included studies did not show a significant impact on psychological status, particularly depression. Subgroup analysis suggested that the M1 stimulation point was more effective than other stimulation points [SMD = -0.45, 95% CI (-0.65, -0.25), p < 0.001]. Other stimulation modalities also demonstrated favorable outcomes when compared to rTMS [SMD = -0.67, 95% CI (-1.09, -0.25), p < 0.01]. CONCLUSION: NIBS has a positive impact on pain relief in patients with CPSP, but does not enhance patients' psychological well-being in terms of anxiety or depression. Furthermore, large-sample, high-quality, and multi-center RCTs are needed to explore the benefits of different stimulation durations and parameters in patients with CPSP. The current study has been registered with Prospero under the registration number CRD42023468419.
ABSTRACT
BACKGROUND: Fusarium graminearum is a devastating fungal pathogen that poses a significant threat to global wheat production and quality. Control of this toxin-producing pathogen remains a major challenge. This study aimed to isolate strains with antagonistic activity against F. graminearum and at the same time to analyze the synthesis of deoxynivalenol (DON), in order to provide a new basis for the biological control of FHB. RESULTS: Total of 69 microorganisms were isolated from the soil of a wheat-corn crop rotation field, and an antagonistic bacterial strain F12 was identified as Burkholderia pyrrocinia by molecular biology and carbon source utilization. F. graminearum control by strain F12 showed excellent biological activities under laboratory conditions (95.8%) and field testing (63.09%). Meanwhile, the DON content of field-treated wheat grains was detected the results showed that F12 have significantly inhibited of DON, which was further verified by qPCR that F12 produces secondary metabolites that inhibit the expression of DON and pigment-related genes. In addition, the sterile fermentation broth of F12 not only inhibited mycelial growth and spore germination, but also prevented mycelia from producing spores. CONCLUSION: In this study B. pyrrocinia was reported to have good control of FHB and inhibition of DON synthesis. This novel B. pyrrocinia F12 is a promising biological inoculant, providing possibilities for controlling FHB, and a theoretical basis for the development of potential biocontrol agents and biofertilizers for agricultural use. © 2024 Society of Chemical Industry.
ABSTRACT
A high-precision binocular camera calibration method is proposed to address the issues of poor calibration accuracy and large calibration errors in current practical applications. This method uses a triangular stereo sphere as the calibration object and employs steps, such as ellipse fitting, Cholesky decomposition, homography matrix solution, and nonlinear optimization, to compute the intrinsic and extrinsic parameters, distortion parameters, and relative pose of the binocular camera. Moreover, this method simplifies the correspondences between primitives, enabling simultaneous calibration of multiple viewpoint cameras. This method is also suitable for both binocular cameras consisting of two different structured monocular cameras and those composed of two image sensors within the same structure. Experimental results showed that this method outperforms traditional algorithms in terms of binocular camera calibration accuracy, calibration errors between left and right cameras, and robustness, resulting in a significant improvement in overall algorithm performance.
ABSTRACT
OBJECTIVE: To evaluate the effect of ginger with P6 acupressure in preventing and treating chemotherapy-induced nausea and vomiting (CINV) in cancer patients. METHOD: A total of 172 participants were randomly divided into the control, ginger, acupressure, and joint groups, who were hospitalized in the Affiliated Hospital of Xuzhou Medical University from February and September 2022. The baseline characteristics, nausea, vomiting, and retching, benefit finding, functional living index-emesis, treatment satisfaction, and adverse reaction, were used in data collection. RESULTS: No significant difference was found in benefit finding and adverse reactions among the four groups (P > 0.05). Ginger significantly improved delayed CINV and function living index-nausea (P < 0.05) but had no significant effect on acute CINV, retching, and delayed vomiting, functional living index-emesis, and treatment satisfaction (P>0.05). Acute nausea and retching, delayed nausea, vomiting, and retching, functional living index-emesis, and treatment satisfaction were effectively improved in the acupressure and joint groups (P < 0.05). CONCLUSION: Ginger with P6 acupressure may contribute to improving CINV in patients undergoing chemotherapy.

ABSTRACT
【Objective】 To systematically evaluate the safety and efficacy of intraoperative cell salvage (IOCS) for placenta previa women undergoing cesarean section. 【Methods】 The PubMed, Web of Science, Embase, the Cochrane Library of clinical trials, China National Knowledge Infrastructure (CNKI) and Wan Fang databases were searched from inception to September 2022. The standardized mean differences (SMDs) or relative risk (RR) and 95% confidence intervals (CIs) and prediction intervals (PIs) regarding the comparison between the IOCS and allogeneic blood transfusion (ABT) groups were analyzed using R software Version 4.1.2 and Stata Version 12.0. 【Results】 Five RCTs and ten retrospective cohort studies were included in this meta-analysis. Analysis of cohort studies showed that compared with the ABT group, women with placenta previa who underwent IOCS had generally higher postoperative hemoglobin (Hb) (SMD, 0.626; 95% CI: 0.103 to 1.149; 95% PI: -1.320 to 2.572) and hematocrit (Hct) (SMD, 0.617; 95% CI: 0.130 to 1.104; 95% PI: -1.084 to 2.317) levels. In RCTs, we observed that placenta previa women undergoing IOCS were almost 72.7% less likely to suffer from adverse events AEs than the ABT group (RR, 0.273; 95% CI, 0.082 to 0.904). The difference in postoperative prothrombin time (PT), activated prothrombin time (APTT), fibrinogen (Fib) concentration, blood urea nitrogen (BUN) and creatinine (Cr) between the IOCS and ABT group did not reach statistical significance. 【Conclusion】 Women with placenta previa who undergo IOCS have higher postoperative Hb and Hct concentrations compared to those treated with ABT. IOCS has no major effects on postoperative coagulation parameters and renal function parameters. IOCS is associated with a significantly lower risk of transfusion-related AEs among women undergoing cesarean section.

ABSTRACT
This paper summarized professor JIA Hongxiao's experience in treating cognitive impairments in schizophrenia patients upon five spirits stored in corresponding viscera theory. By elucidating the cognitive psychological connotation of the five spirits stored in corresponding viscera theory, it is proposed that the cognitive impairment of schizophrenia should be differentiated and treated based on the symptom characteristics of different cognitive domain impairments in schizophrenia. The key pathogenesis of impairments to cognitive domains such as information processing speed, executive control ability and will is kidney deficiency, liver hyperactivity, and heart spirit restlessness, for which the treatment is to boost the kidney and calm the liver, nourish the heart and calm the mind, using Shizhen Anshen Formula (石珍安神方) modifications. The main pathogenesis of memory and attention cognitive impairment is spleen-kidney depletion and lung corporeal soul failing to descend, for which it is suggested to fortify the spleen and supplement kidney, boost lung and direct qi downward using Jianpi Bushen Formula (健脾补肾方) modifications.
ABSTRACT
【Objective】 To investigate the relationship of miRNA gene polymorphisms with blood pressure (BP) responses to the sodium and potassium diet intervention. 【Methods】 In 2004, we recruited 514 participants from 124 families in seven villages of Baoji, Shaanxi Province, China. All subjects were given a three-day normal diet, followed by a seven-day low-salt diet, a seven-day high-salt diet, and finally a seven-day high-salt and potassium supplementation. A total of 19 miRNA single nucleotide polymorphisms (SNPs) were selected for analysis. 【Results】 Throughout the sodium-potassium dietary intervention, the BP of the subjects fluctuated across all phases, showing a decrease during the low-salt period and an increase during the high-salt period, followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet. MiR-210-3p SNP rs12364149 was significantly associated with systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure (MAP) responses to low-salt diet. MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention. In addition, miR-26b-3p SNP rs115254818 was significantly correlated with SBP, DBP and MAP responses to high-salt intervention. MiR-1307-5p SNPs rs11191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet. MiR-4638-3p SNP rs6601178, miR-210-3p SNP rs12364149, miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet. In addition, miR-26b-3p SNP rs115254818 was significantly associated with SBP, DBP and MAP responses to potassium supplementation. MiR-1307-5p SNPs rs11191676, rs2292807, and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation. 【Conclusion】 miRNA gene polymorphisms are associated with BP response to sodium and potassium, suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.
ABSTRACT
【Objective】 To investigate the expressions of H3.3G34W, p63 and SATB2 in giant cell tumor of bone (GCTB) and the effect and value of their combined application in the diagnosis of GCTB. 【Methods】 We collected the samples and medical records of 54 cases of GCTB and 83 cases of non-giant cell tumor of bone (14 cases of aneurysmal bone cyst, 16 cases of chondroblastoma and 53 cases of non-ossifying fibroma) diagnosed between 2020 and 2022 in the Department of Pathology of Honghui Hospital Affiliated to Xi’an Jiaotong University. The expressions of H3.3G34W, p63 and SATB2 were detected by EliVision immunohistochemical method. χ2 test was used to determine whether there are significant differences in the positive rates of H3.3G34W, p63 and SATB2 among all the groups. The combined diagnostic model including H3.3G34W, p63 and SATB2 was established by Logistic regression analysis, and the diagnostic value of the model was evaluated by ROC curve analysis. 【Results】 The positive rates of H3.3G34W, p63 and SATB2 in GCTB group were 81.5%, 90.7% and 92.6%, respectively; the positive rates in NGCTB group were 2.4%, 28.9% and 62.7%. Compared with NGCTB group, the age of GCTB group was significantly older [(41.222±14.849) vs. (16.566±9.439) , P<0.001] , and the prevalence was higher in women than in men (51.9% vs. 48.1%, P<0.001). In addition, compared with the NGCTB group, the positive rates of H3.3G34W (81.5% vs. 2.4%, P<0.001), p63 (90.7% vs. 28.9%, P<0.001) and SATB2 (92.6% vs. 62.7%, P<0.001) were significantly higher in the GCTB group. Univariate regression analysis built a univariate prediction model and ROC curve analysis showed that age (AUC=92.9%, P<0.001), sex (AUC=64.5%, P=0.004), H3.3G34W positive rate (AUC=89.5%, P<0.001), p63 positive rate (AUC=80.9%, P<0.001) and SATB2 positive rate (AUC=65.0%, P=0.003) were independent predictors of diagnosis of giant cell tumor of bone. Multivariate regression analysis (Logistic) constructed a hybrid prediction model. ROC curve analysis suggested that the hybrid model showed better prediction value than the single factor model (AUC=98.4%, P<0.001). 【Conclusion】 H3.3G34W, p63 and SATB2 are effective molecular markers for the diagnosis of GCTB, and their combined application can improve the prediction efficiency of the diagnosis of GCTB.
ABSTRACT
【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.
ABSTRACT
Circular RNAs (circRNAs) are a kind of non-coding RNA (ncRNA) with covalent closed-loop structure. They have attracted more and more attention because of their high stability, evolutionary conservatism, and tissue expression specificity. It has shown that circRNAs are involved in the development of a variety of diseases including malignant tumors recently. Nasopharyngeal carcinoma (NPC) is a malignant tumor that occurs in the nasopharynx and has a unique ethnic and geographical distribution in South China and Southeast Asia. Epstein-Barr virus (EBV) infection is closely related to the development of NPC. Radiotherapy and chemotherapy are the mainstays of treatment for NPC. But tumor recurrence or distant metastasis is the leading cause of death in patients with NPC. Several studies have shown that circRNAs, as gene expression regulators, play an important role in NPC and affect the progression of NPC. This review mainly summarized the research status of abnormally expressed circRNAs in NPC and EBV-encoded circRNAs. We also discussed the possibility of circRNAs as a therapeutic target, diagnostic and prognostic marker for NPC.
ABSTRACT
【Objective】 To investigate the clinical efficacy of preoperative therapeutic plasma exchange(TPE) in preventing acute rejection after ABO incompatible kidney transplantation(ABOi-KT). 【Methods】 Nine patients with ABOi-KT who were admitted to the renal transplant department of our hospital from April 2022 to April 2024 were retrospectively analyzed. They received a total of 28 TPEs before kidney transplantation, and the treatment plan was summarized as follows: The proportion of the substitute fluid, as well as the frequency and volume of TPE were determined based on the patient′s ABO blood group system antibody titer, gender, height, weight, hematocrit and other indicators upon admission. The patient′s relevant laboratory indicators, including hemoglobin, platelets, leukocytes, coagulation function, total protein, albumin, globulin, A/G, creatinine and urea nitrogen upon admission and after TPE were monitored and statistically analyzed. After transplantation, changes in renal function indicators such as ABO blood group system antibody titers, creatinine and urinary excretion were observed, and clinical symptoms of acute rejection, such as swelling, pain and edema in the transplanted kidney area were observed. 【Results】 Nine ABOi-KT patients had an average of about 3 TPEs before transplantation surgery, with an average total volume of approximately 2 500 mL to 3 500 mL per TPE, or approximately about 1.01 to 1.16 plasma volume (PV). After multiple TPEs, pre-transplantation antibody titers decreased by an average of 3 times compared to before TPE. There were no statistically significant differences in Hb, PLT, PT, PTA, INR, TBil, ALB, Cr and BUN (P>0.05), while statistically significant differences were found in WBC, APTT, Fbg, TP, GLB and A/G (P<0.05). After surgery, the creatinine level of 9 patients dropped to approximately 100 to 140 μmol/L, the urine output was normal, and the urine protein dropped to weakly positive or negative values. None of the nine patients experienced acute rejection. 【Conclusion】 TPE can effectively reduce the level of ABO blood group antibody and prevent the occurrence of acute rejection in ABOi-KT patients.
