Effects of foot massage on relieving pain, anxiety and improving quality of life of patients undergone a cervical spine surgery.

BACKGROUND: Long-term recovery of patients undergone cervical spine surgery is of paramount importance to improve their quality of life. In this study we aimed to evaluate the effects of foot massage on relieving pain and anxiety of patients with anterior cervical discectomy and fusion (ACDF). METHODS: Enrolled patients undergone ACDF and diagnosed with anxiety disorder at least six months before surgery were treated with 10-min foot massage on a daily basis for four weeks using sweet almond oil. Patients were assessed by neck pain visual analog pain scale (NP-VAS), neck disability index (NDI) and self-rating anxiety scale. RESULTS: More significant relief in NP-VAS was observed in patients who received foot massage treatment. No significant difference in NDI reduction was seen in patients with or without the treatment. Intervention group demonstrated less anxiety during follow-up (p = 0.021) compared to the control group and more reduction compared to baseline (p = 0.046). In terms of quality of life, while both groups demonstrated improvement in pain relief (p = 0.015 for the intervention group and p = 0.037 for the control group), only the intervention group showed improved mental function (p = 0.031). CONCLUSION: This study found that foot massage was effective in alleviating pain and anxiety, while improving quality of life in patients undergone ACDF, indicating that this intervention should be considered in the clinical management of these patients.

Characterization and expression profiling of glutathione S-transferases in the diamondback moth, Plutella xylostella (L.).

BACKGROUND: Glutathione S-transferases (GSTs) are multifunctional detoxification enzymes that play important roles in insects. The completion of several insect genome projects has enabled the identification and characterization of GST genes over recent years. This study presents a genome-wide investigation of the diamondback moth (DBM), Plutella xylostella, a species in which the GSTs are of special importance because this pest is highly resistant to many insecticides. RESULTS: A total of 22 putative cytosolic GSTs were identified from a published P. xylostella genome and grouped into 6 subclasses (with two unclassified). Delta, Epsilon and Omega GSTs were numerically superior with 5 genes for each of the subclasses. The resulting phylogenetic tree showed that the P. xylostella GSTs were all clustered into Lepidoptera-specific branches. Intron sites and phases as well as GSH binding sites were strongly conserved within each of the subclasses in the GSTs of P. xylostella. Transcriptome-, RNA-seq- and qRT-PCR-based analyses showed that the GST genes were developmental stage- and strain-specifically expressed. Most of the highly expressed genes in insecticide resistant strains were also predominantly expressed in the Malpighian tubules, midgut or epidermis. CONCLUSIONS: To date, this is the most comprehensive study on genome-wide identification, characterization and expression profiling of the GST family in P. xylostella. The diversified features and expression patterns of the GSTs are inferred to be associated with the capacity of this species to develop resistance to a wide range of pesticides and biological toxins. Our findings provide a base for functional research on specific GST genes, a better understanding of the evolution of insecticide resistance, and strategies for more sustainable management of the pest.

Impact of Hydrogen Voiding in Chip-to-Chip Electroless All-Copper Interconnections.

Three-dimensional (3D) integration has become a leading approach in chip packaging. The interconnection density and reliability of micro-bumps in chip stacking are often threatened by high bonding temperatures. The method of building chip-to-chip interconnections by electroless deposition of metal has its distinct merit, while the interfacial defect issue, especially that related to voiding during the merging of opposite sides, remains largely unsolved. In this study, to trace the influencing factors in the voiding, the growth characteristics of the electroless all-copper interconnections were examined by carrying out deposition experiments in a microfluidic channel device. The results show that when the gap between the opposite copper bumps to be electrolessly merged is as low as 10 µm, significant voids appear at the inflow side and the top of the copper bumps because the hydrogen cannot be expelled in time. A finite-element flow model of the plating solution between the chips was established, which showed that the flow rate of the plating solution around the copper bumps was much higher than in the merging gap, causing an uneven supply of reactants. Based on these findings, we proposed two potential solutions, one is to improve the flow mode of the plating solution, and the other is to add the reaction inhibitor, 2,2'-bipyridine. Finally, the combination of these two approaches successfully achieved an improved merging quality of the copper joints.

Protective effects of forsythoside A against severe acute pancreatitis- induced brain injury in mice.

OBJECTIVES: This study aimed to evaluate the therapeutic effects of forsythoside A (FA) on brain injury induced by severe acute pancreatitis (SAP) using a murine model. METHODS: Mice were induced with 3.5 % sodium taurocholate to model SAP-induced brain injury (SAP-IBI) and were randomly assigned to four distinct treatment regimens: the SAP-IBI model group (SAP-IBI), low-dose FA treatment group (FA L+SI), middle-dose FA treatment group (FA M+SI), and high-dose FA treatment group (FA H+SI). A sham-operation group (SO) served as a negative control. Serum levels of interleukin-1ß (IL-1ß) and IL-18 were quantified via ELISA, and serum amylase levels were assessed using optical turbidimetry. mRNA expression levels of AIM2, ASC, Caspase-1, and GAPDH in hippocampal brain tissue were measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Protein levels of NLRP3, GSDMD, IL-1ß, and IL-18 in hippocampal brain tissue were evaluated using Western blotting. Neurological function in surviving mice was assessed through modified neurological severity scores (mNSS). Transmission electron microscopy (TEM) provided ultrastructural analysis of the hippocampus. Additionally, water content and pathological changes in hippocampal brain tissue were examined 24 hours post-operation, along with other relevant indicators. RESULTS: At 24 hours post-operation, the FA H+SI group exhibited significantly reduced levels of serum amylase, IL-1ß, and IL-18, along with decreased expression of AIM2, ASC, and Caspase-1 mRNA. Furthermore, NLRP3 protein levels, water content, pancreas and hippocampal brain pathological scores, and mNSS were significantly lower compared to the SAP-IBI group (P<0.01). CONCLUSIONS: FA demonstrates protective effects against SAP-IBI in mice, suggesting potential therapeutic benefits.

Repeat biopsy versus initial biopsy in terms of complication risk factors and clinical outcomes for patients with non-small cell lung cancer: a comparative study of 113 CT-guided needle biopsy of lung lesions.

Objectives: The safety and feasibility of repeat biopsy after systemic treatment for non-small cell lung cancer have received extensive attention in recent years. The purpose of this research was to compare complication rates between initial biopsy and rebiopsy in non-small cell lung cancer patients with progressive disease and to assess complication risk factors and clinical results after rebiopsy. Methods: The study included 113 patients initially diagnosed with non-small cell lung cancer who underwent lung biopsy at initial biopsy and rebiopsy after progression while on epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) and/or chemotherapy from January 2018 to December 2021. We compared the incidence of complications between the initial biopsy and rebiopsy and analyzed the predictors factors that influenced complications in patients who underwent rebiopsy. Results: The successful rate of rebiopsy was 88.5% (100/113). With the exception of two cases where lung adenocarcinoma changed into small cell lung cancer with gefitinib treatment, 98 individuals retained their initial pathological type. The secondary EGFR T790M mutation accounts for 55.6% of acquired resistance. The total number of patients with complications in initial biopsy was 25 (22.1%) and 37 (32.7%) in the rebiopsy. The incidence of pulmonary hemorrhage increased from 7.1% at the initial biopsy to 10.6% at rebiopsy, while the incidence of pneumothorax increased from 14.2% to 20.4%. Compared with the initial biopsy, the incidence of overall complications, parenchymal hemorrhage, and pneumothorax increased by 10.6%, 3.5%, and 6.2%, respectively. In all four evaluations (pneumorrhagia, pneumothorax, pleural reaction, and overall complication), there were no significant differences between the rebiopsy and initial biopsy (all p > 0.05). The multivariate logistic regression analysis suggested that male sex (odds ratio [OR] = 5.064, p = 0.001), tumor size ≤ 2 cm (OR = 3.367, p = 0.013), EGFR-TKIs with chemotherapy (OR = 3.633, p =0.023), and transfissural approach (OR = 7.583, p = 0.026) were independent risk factors for overall complication after rebiopsy. Conclusion: Compared with the initial biopsy, the complication rates displayed a slight, but not significant, elevation in rebiopsy. Male sex, tumor size ≤ 2 cm, transfissural approach, and EGFR-TKIs combined with chemotherapy were independent risk factors for rebiopsy complications.

Research Progress on Psychological Distress in Patients with Ectopic Pregnancy in China.

Ectopic pregnancy is a leading cause of death for child-bearing aged women. Most patients with ectopic pregnancy experience suffer psychological distress which seriously affects their physical and mental health. The psychological distress, influencing factors, measurement tools, and nursing interventions in patients with ectopic pregnancy in China are reviewed in this article. The results showed that the main psychological distress of patients with ectopic pregnancy is anxiety, depression, uncertainty sense of disease, and low self-esteem. The main factors affecting the psychological distress of ectopic pregnancy patients included life-threatening disease, different marital status, and reproductive needs. The main intervention methods for psychological distress in pregnant patients included: cognitive behavioral therapy, emotional therapy of traditional Chinese medicine, and family support. The majority of cross-sectional surveys in China focused on psychological conditions of the patients with ectopic pregnancy, and there are very few longitudinal studies. Large-sample, multi-center longitudinal studies should be conducted in the future to monitor the development of ectopic pregnancy. Qualitative research should be conducted on patient experience, to provide guidance and basis for the implementation of targeted nursing interventions and to further explore standardized, continuous, and generalizable psychological care protocols for distress interventions for patients with ectopic pregnancy, thereby minimizing psychological distress such as anxiety, depression, and uncertainty in patients with ectopic pregnancy.

Peripheral blood eosinophil levels in chronic rhinosinusitis and its predictive value in eosinophilic chronic rhinosinusitis.

BACKGROUND: The prevalence of eosinophilic CRSwNP in China has increased significantly over the last 20 years, noninvasive methods that could assist in diagnosis are urgently needed. AIMS: The aim of this study is to explore the clinical significance of peripheral blood eosinophil in diagnosing ECRS. MATERIALS AND METHODS: We conducted a prospective study of 221 patients diagnosed with CRS. Lund-Mackay score, peripheral blood eosinophil absolute count, peripheral blood eosinophil percentage were detection to compare the clinical features with ECRS and non-ECRS. ROC curve was performed to assess the efficiency of clinical index to predict ECRS. RESULTS: The ECRS group of patients had significantly higher scores compared with those of the non-ECRS group. Different extent and severity of mucosal thickening on total Lund-Mackay scores, anterior ethmoidal, posterior ethmoidal and ostiomeatal complex have confirmed different blood eosinophil levels in CRS patients. The combination of peripheral blood eosinophil percentage and posterior ethmoidal score to predict ECRS was 0.807. CONCLUSIONS AND SIGNIFICANCE: The increase in peripheral blood eosinophil percent indicates the deterioration the inflammation of chronic rhinosinusitis and the level of posterior ethmoidal score and peripheral blood eosinophil percentage have a positive predictive value regarding ECRS identification.

Sinus Microbiota in Patients With Eosinophilic and Non-Eosinophilic Chronic Rhinosinusitis With Nasal Polyps.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by Th2-skewed inflammation and increased colonization by Staphylococcus aureus. CRSwNP can be distinguished as eosinophilic (ECRSwNP) and non-eosinophilic (NECRSwNP) by the infiltration of eosinophils. The local microbiota plays an important role in the persistent inflammation of CRSwNP. To evaluate the bacterial community composition on the distinct types of CRSwNP patients, we collected nasal swabs from 16 ECRSwNP patients, 18 NECRSwNP patients, and 39 healthy control subjects. The microbiome structure for all the samples were analyzed by high-throughput 16S rRNA gene sequencing. Concentration of S. aureus was determined using TaqMan quantitative polymerase chain reaction (qPCR) targeting the nuclease (nuc) gene. The result showed significant differences in the sinus microbiome among healthy control subjects and CRSwNP patients. Microbiota community diversity was significantly lower in NECRSwNP samples compared to that of healthy control subjects. Interestingly, the abundance of several pathogenic bacteria was diverse between ECRSwNP and NECRSwNP patients. Although Staphylococcus prevailed in all groups, the abundance of Staphylococcus was significantly higher in the healthy control group than the ECRSwNP group. More importantly, the abundance of S. aureus was much higher in NECRSwNP patients. This study highlights that microbiota composition may contribute to the different clinical types of CRSwNP, inspiring new therapeutic strategies to resolve this chronic inflammation process.

Data processing to support explication about effect of mineral constituents on temperature-dependent structural characterization of carbon fractions in sewage sludge-derived biochar.

This dataset is the supplementary data for the summited research article Li et al., 2017 [1] and provides detailed data profiles to support the explication about mineral constituents' effect on temperature-dependent structural characterization of carbon fractions in sewage sludge-derived biochar. The elemental compositions of major inorganics in the sewage sludge were detected by X-ray fluorescence spectrometry (XRF, S2-Ranger, Bruker).The images from scanning electron microscope (SEM) were compared between unwashed and acid-washed samples, and revealed the effect of acid washing on the surface morphology and porosity of sewage sludge and the biochar. Peak deconvolution was conducted for the (002) peak of X-ray diffraction (XRD) patterns from the acid-washed samples, which provided information on structural parameters of the carbon stacking structure and the temperature-dependent structure evolution of sewage sludge biochar. Peak deconvolution was also carried out for Raman data of the samples with/without consideration of mineral constituents (aluminosilicates). Results of Raman peak deconvolution showed structure ordering evolution with pyrolysis temperature and evidenced the contribution of mineral constituents to the Raman signals.

Molecular characterisation of two α-esterase genes involving chlorpyrifos detoxification in the diamondback moth, Plutella xylostella.

BACKGROUND: Carboxylesterases (CarEs) are involved in metabolic detoxification of dietary and environmental xenobiotics in insects. However, owing to the complexity of the protein family, the involvement of CarEs in insecticide metabolism in Plutella xylostella has not been fully elucidated. This study aimed to characterise two CarE genes and assess their potential roles in response to chlorpyrifos in P. xylostella. RESULTS: Synergistic tests showed that triphenyl phosphate decreased the resistance of the third-instar larvae to chlorpyrifos. The treatment of the third-instar larvae with chlorpyrifos at the LC30 dose led to a significant increase in CarE activity. Two CarE cDNAs (Pxae18 and Pxae28) were subsequently sequenced and characterised. Both genes were expressed predominantly in the larval midgut. Most importantly, two CarE genes showed significantly higher expression in the chlorpyrifos-resistant strain than in the susceptible strain. RNAi knockdown of Pxae18 and Pxae28 significantly increased the mortality to chlorpyrifos from 40% in the control to 73.8 and 63.3% respectively. CONCLUSION: RNAi knockdown of Pxae18 and Pxae28 significantly inhibited detoxification ability and increased the mortality in P. xylostella. The results indicate that these two CarE genes play important roles in the detoxification of chlorpyrifos in P. xylostella. © 2016 Society of Chemical Industry.

Generation-based life table analysis reveals manifold effects of inbreeding on the population fitness in Plutella xylostella.

Understanding how inbreeding affects fitness is biologically important for conservation and pest management. Despite being a worldwide pest of many economically important cruciferous crops, the influence of inbreeding on diamondback moth, Plutella xylostella (L.), populations is currently unknown. Using age-stage-specific life tables, we quantified the inbreeding effects on fitness-related traits and demographic parameters of P. xylostella. Egg hatching rate, survival and fecundity of the inbred line significantly declined compared to those of the outbred line over time. The inbred P. xylostella line showed significantly lower intrinsic rate of increase (r), net reproduction rate (R0), and finite increase rate (λ), and increasing generation time (T). Inbreeding effects vary with developmental stages and the fitness-related traits can be profoundly affected by the duration of inbreeding. Our work provides a foundation for further studies on molecular and genetic bases of the inbreeding depression for P. xylostella.
