Effects of Enteromorpha prolifera sulfated polysaccharide and aluminium ion addition on the multifunctional property of conductive hydrogel for wearable strain sensing.

Although introducing Enteromorpha prolifera sulfated polysaccharide (SPEP) enhances the mechanical properties of hydrogels significantly, little is known about the effects of polysaccharide and ion addition on morphological and physicochemical properties of conductive hydrogel. Therefore, the Poly (acrylic acid)/SPEPn/Al3+m (PAA/SPEPn/Al3+m) hydrogels with different SPEP and Al3+ addition were synthesized by simple one-pot method. The porosity, tensile strength, and swelling ration increased, while compressive strength, elongation at break, self-healing, self-adhesion properties increased first and then decreased as SPEP addition increased from 0 % to 3.80 %. The Al3+ addition increased from 0.08 % to 0.30 %, both tensile and compressive strength increased first and then decreased, while elongation at break kept increasing. Unexpectedly, both increasing SPEP and Al3+ addition reduced the electrical conductivity, while SPEP increased the gauge factor of hydrogel. The hydrogel exhibited optimal comprehensive properties when SPEP and Al3+ addition were 2.31 % and 0.24 %, respectively. The PAA/SPEP2.31%/Al3+0.24% hydrogel showed high tensile strength (107.60 kPa), elongation at break (2426.67 %), strain self-healing rate (81.87 %), adhesion strength (21.61 kPa), and conductivity (3.60 S/m). Overall, the properties of PAA/SPEPn/Al3+m hydrogels can be regulated through tailoring SPEP and Al3+ addition, which can be used as on-demand strategy to improve the performance of PAA/SPEPn/Al3+m hydrogels for each application.

Identification, expression, and characterization of a marine-derived chitinase Ce0303 from Chitiniphilus eburneus YS-30 with exo- and endo-hydrolytic properties.

N-acetyl-oligosaccharides exhibit antioxidant and antibacterial activities. However, the low catalytic efficiency of chitinase on crystalline chitin hinders the eco-friendly production of N-acetyl-oligosaccharides. A marine-derived chitinase-producing strain Chitiniphilus eburneus YS-30 was screened in this study. The genome of C. eburneus YS-30 spans 4,522,240 bp, with a G + C content of 63.96 % and 4244 coding genes. Among the chitinases secreted by C. eburneus YS-30, Ce0303 showed the highest content at 19.10 %, with a molecular weight of 73.5 kDa. Recombinant Ce0303 exhibited optimal activity at 50 °C and pH 5.0, maintaining stability across pH 4.0-10.0. Ce0303 demonstrated strict substrate specificity, with a specific activity toward colloidal chitin of 6.41 U mg-1, Km of 2.34 mg mL-1, and kcat of 3.27 s-1. The specific activity of Ce0303 toward α-chitin was 18.87 % of its activity on colloidal chitin. Ce0303 displayed both exo- and endo-hydrolytic properties, primarily producing (GlcNAc)1-3 from colloidal chitin. The structure of Ce0303 includes one catalytic domain and two chitin-binding domains. Docking results revealed that the GlcNAc at -1 subsite formed two hydrogen bonds with conserved Trp380. The hydrolytic properties of Ce0303 will provide technical support for the comprehensive utilization of crustacean raw materials.

Susceptibility of Yellow Squash and Zucchini Cultivars to the Sweetpotato Whitefly, Bemisia tabaci Gennadius (MEAM1), in the Southeastern United States.

The sweetpotato whitefly, Bemisia tabaci (Gennadius) Middle East-Asia Minor 1 (MEAM1), causes significant losses to vegetable crops directly by sap-feeding, inducing plant physiological disorders, and elevating the build-up of sooty mold, and indirectly by transmitting plant viruses. In this study, we evaluated the susceptibility of 20 yellow squash and zucchini (Cucurbita pepo) cultivars to MEAM1, across three growing seasons in the southeastern United States. Weekly sampling of the numbers of MEAM1 adults, nymphs, and eggs were conducted from the fourth week after seed sowing and across 6 weeks during the summer and fall of 2021 and five weeks during the fall of 2022. In general, adult whitefly populations were high during the first week of sampling but decreased as the seasons progressed. The zucchini cultivar 'Black Beauty' harbored the most adults, while 'Green Eclipse Zucchini' was the least attractive zucchini cultivar to the adults in fall 2022. For yellow squash, 'Early Summer' (summer 2021) and 'Amberpic 8455' (summer 2021 and fall 2022) were the cultivars with the highest adult populations, while 'Lioness' (summer 2021) and 'Gourmet Gold Hybrid' (fall 2022) harbored the lowest adult counts. The whitefly egg counts across both vegetables trailed those of adults and peaked in the second week of sampling. The counts of nymphs increased as the seasons progressed, but there was a decline after the second week during fall 2021. For the yellow squash cultivars, 'Gourmet Gold Hybrid', (summer 2021 and fall 2022), 'Lioness', and 'Fortune' (summer 2021) recorded the highest yields. For zucchini, 'Golden Glory' (summer 2021) was the top performer. These results provide valuable information for whitefly management in yellow squash and zucchini based on host plant susceptibility and yield.

Yi-Shen-Hua-Shi regulates intestinal microbiota dysbiosis and protects against proteinuria in patients with chronic kidney disease: a randomized controlled study.

CONTEXT: Yi-Shen-Hua-Shi (YSHS) is a traditional Chinese medicine that treats chronic kidney disease (CKD). However, its efficacy in reducing proteinuria and underlying mechanisms is unknown. OBJECTIVE: This single-center randomized controlled trial explored whether YSHS could improve proteinuria and modulate the gut microbiota. MATERIALS AND METHODS: 120 CKD patients were enrolled and randomized to receive the renin-angiotensin-aldosterone system (RAAS) inhibitor plus YSHS (n = 56) or RAAS inhibitor (n = 47) alone for 4 months, and 103 patients completed the study. We collected baseline and follow-up fecal samples and clinical outcomes from participants. Total bacterial DNA was extracted, and the fecal microbiome was analyzed using bioinformatics. RESULTS: Patients in the intervention group had a significantly higher decrease in 24-h proteinuria. After 4 months of the YSHS intervention, the relative abundance of bacteria that have beneficial effects on the body, such as Faecalibacterium, Lachnospiraceae, Lachnoclostridium, and Sutterella increased significantly, while pathogenic bacteria such as the Eggerthella and Clostridium innocuum group decreased. However, we could not find these changes in the control group. Redundancy analysis showed that the decline in 24-h proteinuria during follow-up was significantly correlated with various taxa of gut bacteria, such as Lachnospiraceae and the Lachnoclostridium genus in the YSHS group. KEGG analysis also showed the potential role of YSHS in regulating glycan, lipid, and vitamin metabolism. DISCUSSION AND CONCLUSION: The YSHS granule reduced proteinuria associated with mitigating intestinal microbiota dysbiosis in CKD patients. The definite mechanisms of YSHS to improve proteinuria need to be further explored. TRIAL REGISTRATION: ChiCTR2300076136, retrospectively registered.

Successful true cavity pathfinding with balloon assisted CTO with bifurcation lesions: Two case reports.

BACKGROUND: Coronary artery disease is a prevalent global cardiovascular ailment, with percutaneous coronary intervention (PCI) standing out as a crucial method for relieving symptoms and enhancing the quality of life in patients with coronary heart disease. However, the presence of concurrent chronic total occlusion (CTO) and bifurcation lesions within coronary arteries elevates the complexity and treatment risks, especially when the entry point of the CTO is ambiguous. OBJECTIVE: This study aims to present an innovative approach for treating CTO complicated with bifurcation lesions, focusing on true cavity pathfinding assisted by a balloon. METHODS: Two cases of CTO patients with concomitant bifurcation lesions are described. One case involves CTO of the left anterior descending artery) combined with anterior non-angle trigeminal lesions, while the other entails CTO of the posterior left artery combined with posterior angle trigeminal lesions. True lumen identification using a balloon and subsequent opening of the CTO blood vessel were performed in both cases. RESULTS: In both cases, the true lumen was successfully located with the assistance of a balloon, leading to the successful opening of the CTO blood vessel. This approach not only simplified the procedure but also reduced procedural difficulty and associated risks of complications compared to traditional guide wire operations. CONCLUSION: The application of true cavity pathfinding assisted by a balloon offers a novel and effective strategy for managing CTO complicated with bifurcation lesions. The method simplifies the procedure, decreases procedural difficulty, and lowers the risk of complications associated with guide wire operations. However, further studies and long-term follow-up data are warranted to validate the reliability and long-term efficacy of this innovative approach.

[Expert consensus for diagnosis and treatment of post-cardiac arrest syndrome in adults by combining traditional Chinese and Western medicine in China (2023)].

Reperfusion injury occurs after return of spontaneous circulation (ROSC) in patients with cardiac arrest (CA), which leads to multiple organ dysfunction, called post-cardiac arrest syndrome (PCAS). PCAS is closely related to the prognosis of CA patients, and is an independent risk factor of survival. Integrated traditional Chinese and Western medicine diagnosis and treatment is critical for improving prognosis of PCAS. In order to guide and standardize integrated traditional Chinese and Western medicine diagnosis and treatment in PCAS among clinicians, nurses and research personnel in China, the Emergency Medicine Professional Committee of the Chinese Society of Integrated Chinese and Western Medicine has established an expert group to determine 14 clinical issues related to the diagnosis and treatment of PCAS with integrated traditional Chinese and Western medicine through clinical survey. The working group formulates a search strategy for each clinical issue according to the PICO principle. Chinese and English literature were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, and Cochrane Library. The grade of recommendations assessment, development and evaluation (GRADE) were used to form the level of evidence and recommendation. When the literature evidence was insufficient, the recommendations and level of recommendation were formed after expert discussion. Combined with the aspects of generalizability, suitability, and resource utilization, the expert consensus developed 28 recommendations around the 14 aspects of three stages of PCAS, including early circulation, respiratory support and reversible cause relief, mid-term neuroprotection, improvement of coagulation, prevention and treatment of infection, kidney and gastrointestinal protection and blood sugar control, post rehabilitation treatment, providing references for the integrated traditional Chinese and Western medicine of the diagnosis and treatment for PCAS.

Self-healing, ultra-stretchable, and highly sensitive conductive hydrogel reinforced by sulfate polysaccharide from Enteromorpha prolifera for human motion sensing.

The synthesis of multifunctional conductive hydrogel has attracted extensive attention worldwide due to their integrated properties of stretchability, self-adhesion, self-healing, and high sensitivity, while it is still a challenge. Although various kinds of polysaccharides and their derivatives are used to achieve the aforementioned objective, there are few researches about hydrogel design introducing sulfated polysaccharide from Enteromorpha prolifera (SPE), which is rich in hydroxyl, sulfate, and carboxyl groups providing amounts of reaction sites for hydrogel synthesis. Herein, conductive hydrogel (PAA-Al3+-SPE3) reinforced by SPE was designed by simple one pot hot polymerization method. This hydrogel demonstrated charming extension ratio (up to 4027.40 %), strain stress (up to 59.94 kPa), compressive strength (19.71 Mpa), and high conductivity sensibility (GF 6.76, 300 % - 700 %). Additionally, PAA-Al3+-SPE3 showed good self-healing property (repaired autonomously after 60 s) and satisfied self-adhesion (31.11 kPa) due to the reversible hydrogen bonds and metal coordination interactions. Furthermore, the PAA-Al3+-SPE3 hydrogel showed great real-time sensing performance to monitor various motions. These findings suggest the potential of PAA-Al3+-SPE3 hydrogel as an affordable and reliable conductive sensing material. Meantime, the first utilization of SPE to construct flexible wearable sensors offers new route for the high-value application of Enteromorpha prolifera.

Mycotoxin Determination in Peaches and Peach Products with a Modified QuEChERS Extraction Procedure Coupled with UPLC-MS/MS Analysis.

Peaches are the most significant temperate fruit crop worldwide. However, peach fruits are susceptible to fungal and mycotoxin contamination. Consequently, monitoring the residual levels of multiple mycotoxins in peaches and related products is essential. In this study, a novel method based on QuEChERS extraction, followed by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) detection, was developed for analyzing 14 mycotoxins in peaches and peach products from China. Matrix-matched calibrations were employed to accurately quantify the mycotoxins and compensate for matrix effects. Recoveries for the target analytes ranged from 84.6% to 117.6%, with intra-day and inter-day precision below 20%. The limits of quantification were 2 or 5 µg/L for the 14 mycotoxins. This method was utilized to detect the presence of target mycotoxins in 109 fresh peaches, 100 diseased peaches, and 89 peach products from China. Six mycotoxins were identified in the rotten parts of the diseased peaches, with concentrations ranging from 5.2 to 1664.3 µg/kg. In the remaining parts of the diseased peach samples, only two toxins, alternariol (AOH) and alternariol monomethyl ether (AME), were quantified at levels of 15.3 µg/kg and 15.5 µg/kg, respectively. No mycotoxins were detected in fresh peaches. For peach products, all contamination levels were below the quantitative limits and significantly lower than the maximum legal limits established for the products.

Molecular action mechanisms of two novel and selective calcium release-activated calcium channel antagonists.

The prototypical calcium release-activated calcium (CRAC) channel, composed of STIM1 and Orai1, is a sought-after drug target for treating autoimmune disorders. Herein, we identified two novel and selective CRAC channel inhibitors, the indole-like compound C63368 and pyrazole core-containing compound C79413, potently and reversibly inhibiting the CRAC channel with low micromolar IC50s and sparing various off-target ion channels. These two compounds did not inhibit STIM1 activation or its coupling with Orai1, nor did they affect the channel's calcium-dependent fast inactivation. Instead, they directly acted on the Orai1 protein, with the channel's pore geometry profoundly affecting their potencies. In vitro, C63368 and C79413 effectively inhibited Jurkat cell proliferation and cytokines production in human T lymphocytes. Intragastric administration of C63368 and C79413 to mice yielded great therapeutic benefits in psoriasis and colitis animal models of autoimmune disorders, reducing serum cytokines production and significantly relieving pathological symptoms. It's worth noting, that this study provided the first insight into the characterization and mechanistic investigation of an indole-like CRAC channel antagonist. Altogether, the identification of these two highly selective CRAC channel antagonists, coupled with the elucidation of their action mechanisms, not only provides valuable template molecules but also offers profound insights for drug development targeting the CRAC channel.

Metabolomic and transcriptomic analyses of the flavonoid biosynthetic pathway in blueberry (Vaccinium spp.).

As a highly economic small fruit crop, blueberry is enjoyed by most people in terms of color, taste, and rich nutrition. To better understand its coloring mechanism on the process of ripening, an integrative analysis of the metabolome and transcriptome profiles was performed in three blueberry varieties at three developmental stages. In this study, 41 flavonoid metabolites closely related to the coloring in blueberry samples were analyzed. It turned out that the most differential metabolites in the ripening processes were delphinidin-3-O-arabinoside (dpara), peonidin-3-O-glucoside (pnglu), and delphinidin-3-O-galactoside (dpgal), while the most differential metabolites among different varieties were flavonols. Furthermore, to obtain more accurate and comprehensive transcripts of blueberry during the developmental stages, PacBio and Illumina sequencing technology were combined to obtain the transcriptome of the blueberry variety Misty, for the very first time. Finally, by applying the gene coexpression network analysis, the darkviolet and bisque4 modules related to flavonoid synthesis were determined, and the key genes related to two flavonoid 3', 5'-hydroxylase (F3'5'H) genes in the darkviolet module and one bHLH transcription factor in the bisque4 module were predicted. It is believed that our findings could provide valuable information for the future study on the molecular mechanism of flavonoid metabolites and flavonoid synthesis pathways in blueberries.

A Single-Center Study Using IVUS to Guide Rotational Atherectomy for Chronic Renal Disease's Calcified Coronary Artery.

Objective: To assess the effectiveness and safety of an IVUS-guided rotational atherectomy (RA) percutaneous coronary intervention (PCI) in chronic renal patients with complex coronary calcification who are at risk for contrast-related acute kidney injury (AKI). Methods: From October 2018 to October 2021, 48 patients with chronic renal disease who were receiving PCI with RA at the General Hospital of NingXia Medical University were informed for data collection for this research. They were randomly assigned to the IVUS-guided RA group and the Standard RA group, which did not use IVUS. According to a clinical expert consensus document on rotational atherectomy in China, both PCI procedures were performed. The intravascular ultrasound (IVUS) results from the study group were used to describe the morphology of the lesion and to guide the selection of burrs, balloons, and stents. IVUS and angiography were used to evaluate the outcome in the end. IVUS-guided RA PCI and Standard RA PCI groups' effects and results were contrasted. Results: There were no appreciable differences in the clinical baseline characteristics between the IVUS-guided RA PCI group and the Standard RA PCI group. The average estimated glomerular filtration rate (eGFR) of two groups was (81.42 ± 20.22 vs 82.34 ± 22.19) mL/min/1.73 m2. Most of them (45.8% vs 54.2%) was in stage 60-90 mL/min/1.73m2. When compared to the standard RA PCI group, RA in IVUS-Guided group was more performed electively (87.5% vs 58.3%; p = 0.02). The IVUS-guided RA PCI group was associated with shorter fluoroscopy time (20.6 ± 8.4 vs 36 ± 22; p<0.01) and less contrast amount (32 ±16 vs 184 ±116mL; p<0.01) than Standard-RA group. Five patients in the Standard RA PCI group developed contrast-induced nephropathy, which was 5 times than the IVUS-guided RA PCI group (20.8% VS 4.1%; p=0.19). Conclusion: In chronic renal patients with complex coronary calcification, an IVUS-guided RA PCI technique is effective and safe. It can also lower the volume of contrast and perhaps the incidence of contrast-related AKI.

Comprehensive review on patulin and Alternaria toxins in fruit and derived products.

Mycotoxins are toxic secondary metabolites produced by certain fungi, which can contaminate various food commodities, including fruits and their derived products. Patulin and Alternaria toxins are among the most commonly encountered mycotoxins in fruit and their derived products. In this review, the sources, toxicity, and regulations related to these mycotoxins, as well as their detection and mitigation strategies are widely discussed. Patulin is a mycotoxin produced mainly by the fungal genera Penicillium, Aspergillus, and Byssochlamys. Alternaria toxins, produced by fungi in the Alternaria genus, are another common group of mycotoxins found in fruits and fruit products. The most prevalent Alternaria toxins are alternariol (AOH) and alternariol monomethyl ether (AME). These mycotoxins are of concern due to their potential negative effects on human health. Ingesting fruits contaminated with these mycotoxins can cause acute and chronic health problems. Detection of patulin and Alternaria toxins in fruit and their derived products can be challenging due to their low concentrations and the complexity of the food matrices. Common analytical methods, good agricultural practices, and contamination monitoring of these mycotoxins are important for safe consumption of fruits and derived products. And Future research will continue to explore new methods for detecting and managing these mycotoxins, with the ultimate goal of ensuring the safety and quality of fruits and derived product supply.

[Chinese consensus of cardiopulmonary resuscitation guides prevention, treatment and rescue of cardiac arrest in pregnancy].

Pregnant women are a group of people in a special period, once sudden cardiac arrest (CA) occurs, it will threaten the life of both mother and child. It has become a great challenge for hospital, doctors and nurses to minimize maternal mortality during pregnancy. All the efforts should ensure the safety of both mother and child throughout the perinatal period. Because difference of the cardiopulmonary resuscitation strategies for common CA patients of the same age, the resuscitation strategies for CA patients during pregnancy need consider the patient's gestational age and fetal condition. Different resuscitation techniques, such as manual left uterine displacement (MLUD), will involve perimortem cesarean delivery (PMCD). At the same time, drugs should be reasonably used for different causes of CA during pregnancy, such as hypoxemia, hypovolemia, hyperkalemia or hypokalemia and other electrolyte disorders and hypothermia in 4Hs, as well as thrombosis, pericardial tamponade, tension pneumothorax and toxicosis in 4Ts. In view of the fact that many causes of CA in pregnancy are preventable, it is more necessary to introduce guidelines for CA in pregnancy in line with our national conditions for clinical guidance. This paper systematically reviewed the pathophysiological characteristics of CA during pregnancy, the high-risk factors of CA during pregnancy, and identified the correct resuscitation methods and prevention and treatment strategies of CA during pregnancy.

[Regulatory effects of umbilical cord mesenchymal stem cells and their conditioned medium on gut microbiota of septic mice].

OBJECTIVE: To investigate and compare the regulatory effects of umbilical cord mesenchymal stem cells (MSC) and their conditioned medium (MSC-CM) on gut microbiota of septic mice. METHODS: Twenty-eight six-to-eight-week-old female C57BL/6J mice were randomly divided into sham operation group (Sham group), sepsis model group (CLP group), sepsis+MSC treatment group (CLP+MSC group) and sepsis+MSC-CM treatment group (CLP+MSC-CM group), with seven mice in each group. The septic mouse model was established by cecal ligation and puncture (CLP). In Sham group, CLP were not performed, and other operations were the same as CLP group. Mice in the CLP+MSC group and CLP+MSC-CM group received 0.2 mL 1×106 MSC or 0.2 mL concentrated MSC-CM via intraperitoneal injection 6 hours after CLP, respectively. Sham group and CLP group were given 0.2 mL sterile phosphate buffer saline (PBS) via intraperitoneal injection. Histopathological changes were evaluated by hematoxylin-eosin (HE) staining and colon length. Levels of inflammatory factors in serum were detected by enzyme-linked immunosorbent assay (ELISA). Phenotype of peritoneal macrophages was analyzed by flow cytometry, and the gut microbiota was analyzed via 16S rRNA sequencing. RESULTS: Compared with Sham group, significant inflammatory injury in lung and colon was observed, and shorter colon was detected in CLP group (cm: 6.00±0.26 vs. 7.11±0.09), the level of inflammatory cytokine interleukin-1ß (IL-1ß) in serum was significantly increased (ng/L: 432.70±17.68 vs. 353.70±17.01), the proportion of F4/80+ peritoneal macrophages was increased [(68.25±3.41)% vs. (50.84±4.98)%], while the ratio of F4/80+CD206+ anti-inflammatory peritoneal macrophages was decreased [(45.25±6.75)% vs. (66.66±3.36)%]. The α diversity sobs index of gut microbiota was downregulated significantly (118.50±23.25 vs. 255.70±6.87), the structure of species composition was altered, and the relative abundance of functional gut microbiota related to transcription, secondary metabolites biosynthesis, transport and catabolism, carbohydrate transport and metabolism, and signal transduction were decreased significantly in CLP group (all P < 0.05). Compared with CLP group, upon MSC or MSC-CM treatment, the pathological injury in lung and colon was alleviated to varying extent, the length of colon was increased (cm: 6.53±0.27, 6.87±0.18 vs. 6.00±0.26), the level of IL-1ß in serum was downregulated (ng/L: 382.10±16.93, 343.20±23.61 vs. 432.70±17.68), the ratio of F4/80+ peritoneal macrophages was decreased [(47.65±3.93)%, (48.68±2.51)% vs. (68.25±3.41)%], the ratio of F4/80+CD206+ anti-inflammatory peritoneal macrophages was increased [(52.73±5.02)%, (66.38±4.73)% vs. (45.25±6.75)%], and the α diversity sobs index of gut microbiota was increased (182.50±16.35, 214.00±31.18 vs. 118.50±23.25), and the effects of MSC-CM were more significant (all P < 0.05). At the same time, species composition of gut microbiota was rebuilt, and a tendency of increase in relative abundance of functional gut microbiota was observed upon MSC and MSC-CM treatment. CONCLUSIONS: Both MSC and MSC-CM could alleviate inflammatory injury in tissues, and showed regulatory effects on gut microbiota in septic mouse model, moreover, MSC-CM exhibited superior advantages over MSC.

Population Dynamics of Insect Pests and Beneficials on Different Snap Bean Cultivars.

Snap bean is an important crop in the United States. Insecticides are commonly used against pests on snap bean, but many pests have developed resistance to the insecticides and beneficials are threatened by the insecticides. Therefore, host plant resistance is a sustainable alternative. Population dynamics of insect pests and beneficials were assessed on 24 snap bean cultivars every week for six weeks. The lowest number of sweetpotato whitefly (Bemisia tabaci) eggs was observed on cultivar 'Jade', and the fewest nymphs were found on cultivars 'Gold Mine', 'Golden Rod', 'Long Tendergreen', and 'Royal Burgundy'. The numbers of potato leafhopper (Empoasca fabae) and tarnished plant bug (Lygus lineolaris) adults were the lowest on cultivars 'Greencrop' and 'PV-857'. The highest numbers of adults were found in Week 1 (25 days following plant emergence) for B. tabaci and Mexican bean beetle (Epilachna varivestis); Week 3 for cucumber beetle, kudzu bug (Megacopta cribraria), and E. fabae; Weeks 3 and 4 for thrips; Week 4 for L. lineolaris; and Weeks 5 and 6 for bees. Temperature and relative humidity correlated with B. tabaci, E. varivestis, bee, and predator ladybird beetle populations. These results provide valuable information on the integrated pest management of snap beans.

[Genetic analysis of a Chinese pedigree affected with Mucopolysaccharidosis type â ¢A].

OBJECTIVE: To explore the clinical and genetic characteristics of a patient with hypertrophic cardiomyopathy as the initial manifestation of Mucopolysaccharidosis type Ⅲ A (MPS Ⅲ A). METHODS: A female patient with MPS Ⅲ A who was admitted to the Affiliated Hospital of Jining Medical University in January 2022 and her family members (seven individuals from three generations) were selected as the study subjects. Clinical data of the proband were collected. Peripheral blood samples of the proband was collected and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing. Heparan-N-sulfatase activity was determined for the disease associated with the variant site. RESULTS: The proband was a 49-year-old woman, for whom cardiac MRI has revealed significant thickening (up to 20 mm) of left ventricular wall and delayed gadolinium enhancement at the apical myocardium. Genetic testing revealed that she has harbored compound heterozygous variants in exon 17 of the SGSH gene, namely c.545G>A (p.Arg182His) and c.703G>A (p.Asp235Asn). Based on guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PM2_Supporting +PM3+PP1Strong+PP3+PP4; PS3+PM1+PM2_Supporting +PM3+PP3+PP4). Sanger sequencing confirmed that her mother was heterozygous for the c.545G>A (p.Arg182His) variant, whilst her father, sisters and her son were heterozygous for the c.703G>A (p.Asp235Asn) variant. Determination of blood leukocyte heparan-N-sulfatase activity suggested that the patient had a low level of 1.6 nmol/(g·h), whilst that of her father, elder and younger sisters and son were all in the normal range. CONCLUSION: The compound heterozygous variants of the SGSH gene probably underlay the MPS ⅢA in this patient, for which hypertrophic cardiomyopathy is an associated phenotype.

Construction of nursing-sensitive quality indicators for epilepsy in China: A Delphi consensus study.

OBJECTIVE: The quality and safety of epilepsy care are of great importance because seizures are unpredictable. The aim of this study was to develop a set of nursing-sensitive quality indicators (NSQIs) for assessing and improving the quality of epilepsy nursing care in China. METHODS: An international literature review, a cross-sectional survey and a qualitative study were conducted to identify candidate NSQIs for epilepsy care and compile a questionnaire. Then, two rounds of electronic Delphi studies were conducted with a panel of 27 independent experts to identify the final NSQIs for epilepsy. RESULTS: Thirty-nine candidate NSQIs were extracted for the Delphi process. The recovery rates in the first and second rounds of expert consultations were 92.6% and 96.2%, respectively. The experts' authority coefficients of the two rounds were 0.876 and 0.878, respectively. The Kendall W value of the two rounds ranged between 0.094 and 0.200 (p<0.001). Eight structure indicators, 9 process indicators and 7 outcome indicators that represented the following three domains were included in the set of NSQIs for epilepsy: nursing resource allocation, implementation of nursing care, and outcomes of patients with epilepsy. CONCLUSION: These NSQIs for epilepsy provide a primary foundation for monitoring and improving the quality of epilepsy nursing care in China. However, the effects of these indicators on improvements in epilepsy care and outcomes in patients need to be verified in clinical practice.
