ABSTRACT Objective: The purpose of this paper is to summarize the blood purification technology applied in patients with severe fever with thrombocytopenia syndrome (SFTS) in the clinical treatment effect. Methods: The medical records of 96 patients with severe SFTS admitted to Weihai Municipal Hospital affiliated to Shandong University from May 2014 to November 2019 were retrospectively analyzed, and they were divided into survival group and death group. The differences in basic data test indexes and treatment method selection during intensive care unit (ICU) admission between the two groups were significantly analyzed, and the indexes with statistically significant differences were included in the multivariate logistic regression analysis related to prognosis. Results: There were no statistically significant differences in age, sex composition, white blood cell count, platelet count, creatine kinase (CK), activated partial thromboplastin time (APTT), serum creatinine and hemofiltration renal replacement therapy between the survival group and the death group. There were statistically significant differences between the two groups in viral load bilirubin and the treatment methods of plasma exchange (PE) or hemoperfusion (HP). Plasma exchange group (78 cases), hemofiltration group (12 cases), hemoperfusion group (6 cases), plasma exchange and hemoperfusion and other blood purification treatment of the prognosis were statistically different. Conclusions: Compared with the three blood purification methods, plasmapheresis has a significant effect on virus removal, improvement of coagulation function and survival rate in patients with severe SFTS. Hemofiltration plays a role in removing inflammatory mediators, replacing renal function, maintaining electrolytes and acid-base balance, but not in removing viruses.

ABSTRACT Carotenoids are fat-soluble bio pigments often responsible for red, orange, pink and yellow coloration of fruits and vegetables. They are commonly referred as nutraceutical which is an alternative to pharmaceutical drugs claiming to have numerous physiological benefits. However their activity often get disoriented by photonic exposure, temperature and aeration rate thus leading to low bioavailability and bio accessibility. Most of the market value for carotenoids revolves around food and cosmetic industries as supplement where they have been continuously exposed to rigorous physico-chemical treatment. Though several encapsulation techniques are now in practice to improve stability of carotenoids, the factors like shelf life during storage and controlled release from the delivery vehicle always appeared to be a bottleneck in this field. In this situation, different technologies in nanoscale is showing promising result for carotenoid encapsulation and delivery as they provide greater mass per surface area and protects most of their bioactivities. However, safety concerns related to carrier material and process must be evaluated crucially. Thus, the aim of this review was to collect and correlate technical information concerning the parameters playing pivotal role in characterization and stabilization of designed vehicles for carotenoids delivery. This comprehensive study predominantly focused on experiments carried out in past decade explaining how researchers have fabricated bioprocess engineering in amalgamation with nano techniques to improve the bioavailability for carotenoids. Furthermore, it will help the readers to understand the cognisance of carotenoids in nutraceutical market for their trendy application in food, feed and cosmeceutical industries in contemporary era.

ABSTRACT This study analyzed sequencing and clinical data from the Cancer Genome Atlas (TCGA) and gene expression synthesis, and used Chinese glioma Genome Atlas (CGGA) data for external validation. The expression of DCP2 in normal brain and tumor tissue was compared. We analyzed the clinical and molecular characteristics and prognostic value of DCP2 in glioma. In addition, DCP2 expression levels were evaluated in 30 glioma tissue samples and upregulated in glioma samples compared to normal brain tissue (p < 0.001). Multivariate data analysis from TCGA showed that increased DCP2 expression was an independent risk factor for overall survival and prognosis of glioma patients. As indicated by the analysis of the TCGA data set. The expression level of DCP2 is closely related to tumor immunity, including tumor immune cell infiltration, immune score, and co-expression of multiple immune-related genes. In addition, DCP2 was positively correlated with IL-6 and IL-7. Glioma cell proliferation and invasion were evaluated using cell viability, colony formation, wound healing, and transwell assays.Apoptosis and cell cycle were detected by flow cytometry. DCP2 promoted the proliferation, invasion and migration of glioma cells T98G and U251, inhibited apoptosis and blocked the S phase of the cell cycle. As a result of the altered expression of DCP2, a new prognostic biomarker may be identified that can improve patient survival.These findings suggest DCP2 as a potential biomarker for the prognosis of glioma and a candidate immunotherapy target.

ABSTRACT Traditional therapeutic approaches in the treatment of cancer have many side effects and are often ineffective and non-specific, leading to the development of therapy-resistant tumour cells. Recently, numerous discoveries about stem cells have given a new outlook on their application in oncology. Stem cells are unique because of their biological attributes, including self-renewal, differentiation in different types of specialized cells and synthesis of molecules that interplay with tumour niche. They are already used as an effective therapeutic option for haematological malignancies, such as multiple myeloma and leukaemia. The main goal of this study is to investigate the possible applications of different types of stem cells in cancer treatment and to summarize novel advances, as well as the limitations of their application in cancer treatment. Research and clinical trials that are underway revealed and confirmed the enormous potential of regenerative medicine in the treatment of cancer, especially when combined with different nanomaterials. Nanoengineering of stem cells has been the focus of novel studies in the area of regenerative medicine, such as the production of nanoshells and nanocarriers that enhance the transport and uptake of stem cells in their targeted tumour niche and enable the effective monitoring of stem cell effects on tumour cells. Although nanotechnology has a lot of limitations, it provides new opportunities for the development of effective and innovative stem cell therapies.

ABSTRACT Pruritic dermatoses and sleep disorders have significant impacts on the health and quality of life of patients. Inflammatory conditions may lead to the sensation of itching. This study was to evaluate the association between pruritic dermatoses and inflammatory factors on sleep disorders. Data in the cross-sectional study were extracted from the National Health and Nutrition Examination Survey. The study population was divided into participants with and without sleep disorders. Pruritic dermatoses were assessed by the participant’s self-report. Inflammatory factors included white blood cell count (WBC), lymphocyte count (LYM) and prognostic nutritional index (PNI). Logistic regression models were used with odds ratios and confidence intervals. The attributable proportion of interaction (AP) was utilized to assess the interaction between pruritic dermatoses and inflammatory factors on sleep disorders. Totally, 3,520 participants were included and 214 (6.08%) had sleep disorders. Pruritic dermatoses were associated with sleep disorders after adjusting for gender, age, race, marital status, body mass index, drinking, smoking, asthma, hay fever, allergy, depression and caffeine. LYM was associated with sleep disorders when inflammatory factors were divided by median. The interaction between participants without pruritic dermatoses and PNI < median on sleep disorders was observed compared to participants without pruritic dermatoses and PNI > median. Pruritic dermatoses were significantly associated with sleep disorders. We also found that a high level of PNI had an enhanced effect on the relationship between pruritic dermatoses and sleep disorders. Clinicians should focus on the potential sleep-related risks and changes in inflammatory factors in patients with pruritic dermatoses and intervene in time.

ABSTRACT Hyperuricemia (HUA) is a common complication of chronic kidney disease (CKD). Conversely, HUA can promote the disease progression of CKD. However, the molecular mechanism of HUA in CKD development remains unclear. In the present study, we applied ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to analyze the serum metabolite profiling of 47 HUA patients, 41 non-hyperuricemic CKD (NUA-CKD) patients, and 51 CKD and HUA (HUA-CKD) patients, and then subjected to multivariate statistical analysis, metabolic pathway analysis and diagnostic performance evaluation. Metabolic profiling of serums showed that 40 differential metabolites (fold-change threshold (FC) > 1.5 or<2/3, variable importance in projection (VIP) > 1, and p < 0.05) were screened in HUA-CKD and HUA patients, and 24 differential metabolites (FC > 1.2 or<0.83, VIP>1, and p < 0.05) were screened in HUA-CKD and NUA-CKD patients. According to the analysis of metabolic pathways, significant changes existed in three metabolic pathways (compared with the HUA group) and two metabolic pathways (compared with the HUA-CKD group) in HUA-CKD patients. Glycerophospholipid metabolism was a significant pathway in HUA-CKD. Our findings show that the metabolic disorder in HUA-CKD patients was more serious than that in NUA-CKD or HUA patients. A theoretical basis is provided for HUA to accelerate CKD progress.

ABSTRACT We investigate the role and mechanism of imbalance via Th9 cells and Th17/Treg cells in the inflammatory and fibrotic phases of pulmonary fibrosis in mice. A total of mice were split into normal saline (control group) and inflammation and fibrosis mouse models (study group) randomly, and lung tissues and bronchoalveolar lavage fluid (BALF) were obtained from mice at the inflammatory and fibrotic phases on the 7th and 28th day, respectively. The degenerative changes in the mouse lung tissue were then visible using H&E staining. The expression of CCR6 and IL-9 in the lung tissues of two groups was examined through an immunohistochemistry assay. Fluorescence PCR was used to assess the expression of PU.1 mRNA in BALF, and flow cytometry was performed to identify the expression of Th17 and Treg. (1). The level of pulmonary fibrosis and lung inflammation in the research group was significantly higher than in the control group. (2). The expression of Th17, CCR6, IL-9 and PU.1 mRNA was substantially higher (P<0.05) in the research group at different time points; the expression level of Treg cells was considerably lower (P<0.05) in the research group than in the control group. (3). CCR6, IL-9 and PU.1 mRNA levels were statistically directly associated (P<0.05) with Th17 and inversely correlated 40 with Regulatory T cells (Tregs). CCR6 and Th9 cells may be involved in 45 developing Th17/Treg imbalance in the immune inflammation of pulmonary fibrosis, which promotes fibrocyte proliferation in lung tissue.

ABSTRACT Hyperbilirubinemia (HY) is a common condition in neonates that requires phototherapy treatment. This study aimed to evaluate the effectiveness of transcutaneous bilirubin measurements (TCB), hypersensitive C-reactive protein (hs-CRP), and unconjugated bilirubin (UCB)/albumin (ALB) as indicators of HY during neonatal phototherapy. A research group of 67 neonates with pathological HY and a control group of 55 healthy neonates were selected from a hospital between June 2020 and May 2021. TCB, hs-CRP, and UCB/ALB tests were performed before, during (at 3 days of treatment), and after (at 6 days of treatment) phototherapy in the research group and at admission in the control group. The study also included a 1-year prognostic follow-up on the research group. The study observed the difference in TCB, hs-CRP, and UCB/ALB test results between both groups and their assessment effect on adverse reactions, treatment effects, and poor prognosis in phototherapy. TCB, hs-CRP, and UCB/ALB levels were higher in the research group than in the control group and gradually decreased during phototherapy (P < 0.05). The combined TCB, hs-CRP, and UCB/ALB assay had 100.0% sensitivity and 64.58% specificity (P < 0.001) for predicting adverse reactions, 88.24% sensitivity and 80.00% specificity (P < 0.001) for predicting the effect of phototherapy, and 90.91% sensitivity and 88.89% specificity (P < 0.001) for predicting poor prognosis. The combined TCB, hs-CRP, and UCB/ALB assay showed superior assessment of adverse effects, clinical outcomes, and poor prognosis in HY neonates treated with phototherapy. TCB, hs-CRP, and UCB/ALB could be used as dynamic disease assessment indicators for HY to better prevent and treat the occurrence of HY.

ABSTRACT This paper uses Meta-analysis to explore the differences in the clinical efficacy of combined Chinese and Western medical treatment of pit viper bites versus Western medicine alone. By searching English databases (PubMed, Embase and Cochrane Library) and Chinese databases (CNKI, Wanfang and VIP), we collected original studies related to this problem. After data extraction, meta-analysis was performed using 5.2–0 in R language. In this study, a total of 7891 patients with pit viper bites were included in 9 studies. Combined Chinese and Western medicine treatment may be superior to Western medicine treatment alone with an OR of 5.30 and 95% CI of 3.90–7.21. The combined treatment of Chinese and Western medicine has better clinical results in the recovery of local symptoms in patients with pit viper bites and is more effective than conventional Western medicine alone.

ABSTRACT The neutrophil-to-lymphocyte ratio (NLR) has been shown to predict patient outcomes in various disorders. This study was carried out to evaluate the value of NLR in predicting mortality in decompensated cirrhosis patients having transjugular intrahepatic portosystemic shunt (TIPS). The end-stage liver disease model (MELD) is a scoring system to evaluate the liver function reserve. Retrospective investigation was conducted on the clinical information of 244 decompensated cirrhosis individuals with a MELD score ≤15 who underwent TIPS production at two academic medical centres between January 2017 and August 2021. The main result was 12-month post-TIPS mortality. The area under the receiver operating characteristic curve (AUC) was used to investigate the predictive potential of prognostic markers correlated with 12-month mortality using a logistic regression approach. To minimize the effects of potential factors, a 1:2 propensity score matching (PSM) was carried out. The non-surviving group had 21 (8.6%) patients who passed away within 12mo, while the surviving group included 223 (91.4%) patients who survived for more than 12mo. According to the multivariate analyses, NLR>4.8 was an independent prognostic factor of 12-month mortality after PSM analysis (OR=3.4, 95%CI, 1.052-10.985, P =0.041). In comparison to the non-surviving group, the proportion of NLR-high (>4.8) cells in the surviving group were considerably greater (71.4%vs.38.1%, P =0.017). Whether Unmatched group or the Matched group, NLR exhibited the highest diagnostic performance (AUCs of 0.646 and 0.667, respectively, P <0.05). The NLR is a reasonable and effective indicator of 12-month mortality in decompensated cirrhosis patients with a MELD ≤15 receiving TIPS.
