Sugarcane (Saccharum spp.) is an important sugar crop. Biotic and abiotic stresses such as diseases, cold, and drought are major factors limiting sugarcane production. β-1,3-glucanase (EC 3.2.1.39), a member of the pathogenesis-related protein family, plays an essential role not only in the plant defenses against pathogens but also in plant growth, development, and abiotic stress responses. To systematically investigate the sugarcane β-1,3-glucanase gene family, 132 glycoside hydrolase (GH) 17 family members were identified in the genomes of the sugarcane wild species Saccharum spontaneum 'Np-X', the tropical species S. officinarum 'LA-Purple', and the Saccharum spp. hybrid cultivar 'R570'. The results of the phylogenetic analysis categorized them into four subfamilies, of which subfamily Ⅳ had the largest proportion of members (102). The members of the sugarcane GH17 gene family contained five conserved motifs and 0-16 introns. The majority of the GH17 genes exhibited a genome-wide replication pattern, with 89.50% originating from S. spontaneum 'Np-X' and S. officinarum 'LA-Purple', while 58.10% of them in the Saccharum spp. hybrid cultivar 'R570' belonged to the discrete replication type. Four major classes of cis-acting elements were identified in the promoters, including the elements related to plant growth, development, and tissue-specific expression (14.21%), light-responsive elements (38.24%), biotic or abiotic stress-responsive elements (9.18%), and hormone-responsive elements (38.37%), which suggested that this gene family was involved in plant growth, development, hormone responses, and stress responses. Transcriptome and quantitative real-time PCR (RT-qPCR) analyses showed that the sugarcane GH17 genes exhibited tissue-specific expression and were differentially expressed under low temperature, drought, and hormone treatments, as well as during the interactions between different sugarcane genotypes and Sporisorium scitamineum, suggesting their potential roles in plant defenses. In addition, some SsGlu genes (SsGlu5, SsGlu20, SsGlu21, SsGlu25, SsGlu28, and SsGlu39) were expected to serve as candidate stress-related genes. This study lays a foundation for further revealing the molecular mechanisms of the stress resistance of sugarcane via β-1,3-glucanase genes.

Background: The function of CD69 expressed on T cells in chronic hepatitis B (CHB) remains unclear. We aimed to elucidate the roles of CD69 on T cells in the disease process and in antiviral therapy for CHB. Methods: We enrolled 335 treatment-naive patients with CHB and 93 patients with CHB on antiviral therapy. CD69, antiviral cytokine production by T cells, T-helper (Th) cells, and inhibitory molecules of T cells were measured using flow cytometry, and clinical-virological characteristics were examined dynamically during antiviral therapy. Results: CD69 expression on CD3+, CD4+, and CD8+ T cells was the lowest in the immune-active phase and was negatively correlated with liver transaminase activity, fibrosis features, inflammatory cytokine production by T cells, and Th-cell frequencies but positively with inhibitory molecules on T cells. CD69 expression on CD3+, CD4+, and CD8+ T cells decreased after 48 weeks of antiviral therapy, and patients with hepatitis B e antigen (HBeAg) seroconversion in week 48 showed lower CD69 expression on T cells at baseline and week 48. The area under the ROC curve of CD69 expression on T cells at baseline for predicting HBeAg seroconversion in week 48 was 0.870, the sensitivity was 0.909, and the specificity was 0.714 (P = 0.002). Conclusions CD69 negatively regulates T-cell immunity during CHB, and its expression decreases with antiviral therapy. CD69 expression predicts HBeAg seroconversion in week 48. CD69 may play an important negative role in regulating T cells and affect the efficacy of antiviral therapy.

We retrospectively analyzed therapy efficacy and the adverse reactions of 10 patients suffering from systemic lupus erythematosus (SLE) with intestinal involvement treated with rituximab (RTX). Patients were hospitalized in the Department of Rheumatology and Immunology of the First Medical Center of PLA General Hospital from January 2015 to January 2023. Among the 10 patients, two were men and eight were women. The age of the cohort was (41.9±8.8) years. The age at disease onset was (28.8±9.2) years. The total course of the SLE diagnosis was(109.6±59.9) months. The course of the diagnosis of SLE with intestinal involvement was (89.3±50.2) months. The time from the appearance of intestinal symptoms to the diagnosis of SLE with intestinal involvement was 1.5 (1.0,8.0) months. The time from the diagnosis of SLE with intestinal involvement to RTX use was 13.0 (1.0,46.3) months. Follow-up duration after application of RTX treatment was (55.3±28.4) months. There were five cases of abdominal pain, four cases of abdominal distension, nine cases of diarrhea, three cases of nervous-system involvement, nine cases of lupus nephritis, and seven cases of serositis. All 10 patients underwent computed tomography and radiology of the abdomen. Eight patients had intestinal-wall edema, seven suffered intestinal dilation, four had target signs, three suffered congestion of mesenteric blood vessels, eight had increased mesenteric-fat density, and six had false intestinal obstruction. All 10 patients showed a low level of complement C3 (250-750 mg/L). Nine cases showed a low level of complement C4 (10-90 mg/L). The SLE disease activity index 2000 (SLEDAI-2K) at baseline in 10 patients was 20.5 (17.8, 30.0). After receiving RTX (0.5 g: day 1, day 14, or 375 mg/m 2: day 1, day 14) induction treatment, the intestinal symptoms of 10 cases were relieved completely. Four patients had adverse reactions, of which three received a high-dose glucocorticoid combined with RTX treatment simultaneously. Adverse reactions manifested mainly as a reduced level of IgG and infection with herpes simplex virus in one case, reduced level of IgG and lung infection in one patient, lung infection in one case, and reduced IgG level in one patient. RTX may an efficacious treatment strategy for patients suffering from refractory SLE with intestinal involvement.

This case report described the sucussful treatment of a male infant born at 21 weeks and 4 days through assisted reproductive technology. After prenatal consultation and with the strong desire of the parents, active resuscitation and treatment were performed. The infant received 52 days of mechanical ventilation and was extubated to non-invasive ventilation at a corrected gestational age of 28 weeks and 6 days. During hospitalization, no vasoactive drugs were used, and necrotizing enterocolitis did not occur. The gastric tube was removed at a corrected gestational age of 37 weeks and 4 days. At a corrected gestational age of 40 weeks, cranial MRI showed no abnormalities. The infant was discharged at a corrected gestational age of 42 weeks after 143 days of treatment, without the need for any respiratory support. Follow-up until a corrected age of 6 months showed good growth and development.

AIM:To study the mechanism of Sihei-fang(SHF)in improving pigment deficiency disease(PD)by combining network pharmacology and me-tabolomics.METHODS:Using zebrafish embryos with pigment deficiency disease induced by 1-phe-nyl-2-thiourea(PTU)as an animal model,the ef-fects of SHF extract(0.01,0.02,0.04 mg/mL)on the morphology,melanin area,tyrosinase activity,and melanin content of zebrafish embryos were an-alyzed.Ultra high performance liquid chromatogra-phy-mass spectrometry(UHPLC-MS)was used to screen differential metabolites and obtain relevant metabolic pathways in the SHF treatment of mela-nin deficient zebrafish embryos model.Network pharmacology was used to obtain key targets for SHF treatment of PD and conduct KEGG pathway enrichment analysis.Import The identified differen-tial metabolites and SHF PD intersection targets were imported into the Metscape plugin,to estab-lish a"metabolite reaction enzyme gene"network,and search for key metabolites,targets,and meta-bolic pathways.RESULTS:SHF treatment could in-crease the formation of zebrafish melanin,activate tyrosinase activity,and increase melanin content.Metabolomics analysis obtained 54 differential me-tabolites,and metabolic pathway analysis was con-ducted on these metabolites,involving the biosyn-thesis of phenylalanine,tyrosine,and tryptophan,glycerol phospholipid metabolism,tyrosine metab-olism,linoleic acid metabolism,and aminoacyl tRNA biosynthesis pathways.Network pharmacolo-gy had obtained 55 cross targets of components and diseases.KEGG involved pancreatic cancer,TNF,cancer and other signal pathways.The joint analysis of metabolomics and network pharmacolo-gy identified four key targets:COMT,CYP1B1,TYR,and ALDH2;three key metabolites:L-tyrosine,ho-movanllate,L-lysine;three important metabolic pathways:tyrosine metabolism,valine/leucine/iso-leucine degradation,and lysine metabolism.CON-CLUSION:SHF has a good improvement effect on PD,and combined with metabolomics and network pharmacology,SHF may enhance its influence on the tyrosine metabolism pathway by regulating the metabolite L-tyrosine,thereby promoting the for-mation of melanin.

AIM:This study will clarify whether Wnt5a can be used as a potential diagnostic and therapeutic target for rheumatoid arthritis(RA)and how Xinfeng capsule(XFC)can improve RA through the Wnt5a/β-catenin signaling pathway.METH-ODS:ELISA and RT-qPCR were used to detect in-flammatory factors and pathological genes in the rat model of AA in vivo to investigate the effect of XFC on AA rats.RT-qPCR was used to verify the core genes and key pathways of XFC regulation pre-dicted by network pharmacology.The regulatory mechanism of XFC on Wnt/β-catenin pathway was elucidated by RT-qPCR.Western blot and immuno-fluorescence in primary AA fibroblast-like synovial cells(FLS)in vitro.RESULTS:XFC significantly de-creased the arthritis score and paw swelling in AA rats,and inhibited joint inflammation in AA rats.XFC decreased the levels of inflammatory factors TNF-α and IL-1 in peripheral blood of AA rats,and inhibited the levels of pathological genes MMP3 and fibronectin in joint synovium and AA FLS of AA rats.Network pharmacology predicts that the Wnt pathway is highly correlated with XFC treatment of RA.At the cellular level,serum containing XFC in-hibited the expression of Wnt pathway-related genes β-catenin,CCND1 and c-Myc.The molecular docking results showed that the key components of XFC had strong binding ability to Wnt5a,and the overexpression of Wnt5a(Wnt5a-ove)in AA FLS in-terfered with the action of XFC.CONCLUSION:The expression of Wnt5a is significantly increased in AA FLS and RA FLS,and XFC can inhibit the activation of Wnt/β-catenin signaling pathway to improve RA by binding with Wn5a,providing a new therapeutic mechanism for XFC to improve RA.

Lung cancer is the most common cancer in China and even in the world, and it is also the main cause of cancer death. Patients with anaplastic lymphoma kinase (ALK) gene alterations have the opportunity to receive molecularly targeted therapies. The inhibitors of anaplastic lymphoma kinase, such as ALK-tyrosine kinase inhibitors (ALK-TKIs) significantly prolong the survival of patients. ALK gene variant types include point mutation, amplification, fusion/rearrangement, and ALK fusion is more common than other types. However, the effect of different types of gene changes in molecular targeted therapy is different. Therefore, this paper introduced the relevant contents of different variants of ALK gene, focused on the research progress of targeted therapy, and proposed the future development direction.

Pheretima,also called"earthworms",is a well-known animal-derived traditional Chinese medicine that is extensively used in over 50 Chinese patent medicines(CPMs)in Chinese Pharmacopoeia(2020 edi-tion).However,its zoological origin is unclear,both in the herbal market and CPMs.In this study,a strategy for integrating in-house annotated protein databases constructed from close evolutionary relationship-sourced RNA sequencing data from public archival resources and various sequencing al-gorithms(restricted search,open search,and de novo)was developed to characterize the phenotype of natural peptides of three major commercial species of Pheretima,including Pheretima aspergillum(PA),Pheretima vulgaris(PV),and Metaphire magna(MM).We identified 10,477 natural peptides in the PA,7,451 in PV,and 5,896 in MM samples.Five specific signature peptides were screened and then validated using synthetic peptides;these demonstrated robust specificity for the authentication of PA,PV,and MM.Finally,all marker peptides were successfully applied to identify the zoological origins of Brain Heart capsules and Xiaohuoluo pills,revealing the inconsistent Pheretima species used in these CPMs.In conclusion,our integrated strategy could be used for the in-depth characterization of natural peptides of other animal-derived traditional Chinese medicines,especially non-model species with poorly annotated protein databases.

Objective:To investigate the effects of dexmedetomidine on stress response and postoperative recovery in children undergoing laparoscopic surgery.Methods:A total of 200 pediatric patients undergoing laparoscopic surgery who received treatment in Jinhua Maternal and Child Health Hospital from May 2021 to December 2022 were included in this prospective randomized controlled study. These patients were randomly divided into Group A and Group B. Group A ( n = 100) received an intravenous infusion of physiological saline before anesthesia induction, while Group B ( n = 100) received an intravenous infusion of 0.5 μg/kg dexmedetomidine, and the other anesthesia methods were the same as the Group A. Vital signs (mean arterial pressure, heart rate), stress reactions (norepinephrine, cortisol, blood glucose), postoperative recovery status (eye-opening time, time to orientation, extubation time), the occurrence of restlessness (restlessness score, duration of restlessness), and adverse reactions (nausea, vomiting, tachycardia, laryngeal spasm, respiratory depression) were compared between different time points [before infusion (T0), 10 minutes after infusion (T1), postoperative wakefulness (T2), and 5 minutes after extubation (T3)]. Results:At T1, T2, T3, the mean arterial pressure and heart rate in Group B [(81.53 ± 7.45) mmHg (1 mmHg = 0.133 kPa), (78.32 ± 8.23) mmHg, (85.73 ± 7.28) mmHg, (109.43 ± 7.78) beats/minute, (106.22 ± 7.25) beats/minute, and (112.34 ± 6.74) beats/minute] were significantly higher than those in Group A [(76.39 ± 7.21) mmHg, (73.54 ± 7.41) mmHg, (80.34 ± 6.81) mmHg, (102.58 ± 7.34) beats/minute, (99.14 ± 6.90) beats/minute, (107.76 ± 6.38) beats/minute, t = 4.95, 4.31, 5.40, 6.40, 7.07, 4.93, all P < 0.001]. At 1 day after surgery, the levels of norepinephrine, cortisol, and blood glucose in Group B [(352.73 ± 60.32) ng/L, (310.85 ± 67.61) nmol/L, (4.89 ± 0.97) mmol/L ] were significantly lower than those in Group A [(427.82 ± 72.95) ng/L, (375.33 ± 74.97) nmol/L, (5.53 ± 1.10) mmol/L, t = 7.93, 6.38, 4.36, P < 0.001]. The time to eye-opening, time to orientation, and time to extubation in Group B were (10.06 ± 1.93) minutes, (10.54 ± 2.10) minutes, and (11.92 ± 2.06) minutes, respectively, which were significantly shorter than (11.88 ± 2.14) minutes, (12.43 ± 2.65) minutes, and (14.46 ± 2.43) minutes ( t = 6.31, 5.59, 7.97, all P < 0.001). The pediatric anesthesia emergence delirium score in Group B was (8.19 ± 2.10) points, which was significantly lower than (11.56 ± 2.62) points in Group A ( t = 10.03, P < 0.001). The duration of restlessness in Group A was (7.41 ± 1.27) minutes, which was significantly shorter than (9.33 ± 1.65) minutes in Group B ( t = 9.22, P < 0.001). There was no significant difference in the incidence of adverse reactions between Group A and Group B [8.00% (8/100) vs. 6.00% (6/100), χ2 = 0.30, P > 0.05]. Conclusion:Dexmedetomidine has a good application effect in pediatric laparoscopic surgery. It can stabilize the vital signs of children, reduce stress reactions, facilitate postoperative recovery, and reduce restlessness and adverse reactions.
