Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2012 to 2024, and to provide a scientific basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the incidence data of mumps in Guangxi from 2012 to 2024. Results A total of 159 873 mumps cases were reported from 2012 to 2024 in Guangxi, with an average annual reported incidence of 25.41/100 000, and no death. Mumps occurred every month, with the peak incidence mainly concentrated in April to July and October to January of the next year. There were 96,118 male cases (29.43 /100 000), and 63 755 female cases (21.07 /100 000). The male to female ratio was 1.40:1, and the difference between male and female was significant (χ²=4 321.276，P＜0.05). The annual incidence of mumps showed a certain periodic change, with the incidence peak and trough alternating every 4 - 5 years. The majority of patients were under 15 years old, accounting for 85.32% of the total number of cases. The patients mainly included students, preschool children and scattered children. The highest average incidence was in Nanning City with 40 231 cases (42.08/100 000), and the lowest was in Qinzhou City with 3 466 cases (8.16/100 000). From 2012 to 2024, a total of 210 mumps outbreaks with 4 483 cases were reported in Guangxi. Conclusion The incidence of mumps in Guangxi from 2012 to 2024 shows a periodic change and obvious seasonality. People under 15 years old are the key group at risk of mumps. The prevention and control of the epidemic of mumps in schools and kindergartens should be strengthened. It is suggested to carry out long-term monitoring of mumps as well as immune effect research, and continue to maintain a high vaccination rate of 2 doses of mumps-containing vaccines.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder worldwide, causing dementia and affecting millions of individuals. One prominent characteristic in the brains of AD patients is glucose hypometabolism. In the context of galactose metabolism, intracellular glucose levels are heightened. Galactose mutarotase (GALM) plays a crucial role in maintaining normal galactose metabolism by catalyzing the conversion of β-D-galactose into α-D-galactose (α-D-G). The latter is then converted into glucose-6-phosphate, improving glucose metabolism levels. However, the involvement of GALM in AD progression is still unclear. In the present study, we found that the expression of GALM was significantly increased in AD patients and model mice. Genetic knockdown of GALM using adeno-associated virus did not change the expression of amyloid precursor protein (APP) and APP-cleaving enzymes including a disintegrin and metalloprotease 10 (ADAM10), β-site APP-cleaving enzyme 1 (BACE1), and presenilin-1 (PS1). Interestingly, genetic overexpression of GALM reduced APP and Aβ deposition by increasing the maturation of ADAM10, although it did not alter the expression of BACE1 and PS1. Further electrophysiological and behavioral experiments showed that GALM overexpression significantly ameliorated the deficits in hippocampal CA1 long-term potentiation (LTP) and spatial learning and memory in AD model mice. Importantly, direct α-D-G (20 mg/kg, i.p.) also inhibited Aβ deposition by increasing the maturation of ADAM10, thereby improving hippocampal CA1 LTP and spatial learning and memory in AD model mice. Taken together, our results indicate that GALM shifts APP processing towards α-cleavage, preventing Aβ generation by increasing the level of mature ADAM10. These findings indicate that GALM may be a potential therapeutic target for AD, and α-D-G has the potential to be used as a dietary supplement for the prevention and treatment of AD.

BACKGROUND:Previous studies by our research group discovered that Jiawei Xiaoyao San has a significant anti-liver cancer effect,but the specific mechanism of action was unclear. OBJECTIVE:To investigate the regulatory effects of the traditional Chinese medicine formula Jiawei Xiaoyao San on the levels of miRNAs in plasma exosomes of rats with diethylnitrosamine chronically induced primary liver cancer,based on high-throughput sequencing combined with bioinformatics. METHODS:SD rats were randomly divided into a blank control group,a liver cancer model group,and a Jiawei Xiaoyao San treatment group.Liver cancer models were induced by continuous administration of diethylnitrosamine for 12 weeks.Starting from the 17th week,rats in the Jiawei Xiaoyao San treatment group were administered Jiawei Xiaoyao San once daily until the end of the 20th week,while rats in the blank control and liver cancer model groups were given an equivalent volume of saline.Anti-hepatocellular carcinoma effects were validated by assessing the morphological structure of rat liver tissues,along with the expression of the hepatocellular carcinoma markers,Glypican-3 protein and serum alpha-fetoprotein.Plasma exosomes from each group of rats were isolated using ultracentrifugation.High-throughput sequencing technology was used to screen for differentially expressed miRNAs in rat plasma exosomes.Bioinformatics was used to predict the potential biomarkers through which Jiawei Xiaoyao San exerts its anti-liver cancer effects via liver cancer-derived exosomal miRNAs,followed by functional analysis. RESULTS AND CONCLUSION:(1)Jiawei Xiaoyao San significantly improved the morphological structure of liver tissues in a rat model of liver cancer.Compared with the liver cancer model group,the expression of liver cancer markers Glypican-3 protein and serum alpha-fetoprotein was significantly reduced in the Jiawei Xiaoyao San treatment group.(2)Bioinformatics analysis showed that in the Jiawei Xiaoyao San group,upregulated miR-223-3p in the liver cancer model group had target binding sites with genes E2F1 and NCOA1,which were closely related to liver cancer survival and prognosis.Therefore,Jiawei Xiaoyao San has a therapeutic effect on liver cancer,possibly by targeting negative regulation of NCOA1/E2F1 through liver cancer plasma-derived exosomal miR-223-3p,thereby playing anti-liver cancer effect.

Objective To investigate the effect of subanesthetic dose of esketamine on emergence agitation(EA)in patients undergoing laparoscopic hernia repair.Methods Seventy-two male patients who treated with lapa-roscopic hernia repair under general anesthesia were randomly divided into AS group(subanesthetic esketamine)and control group.In the AS group,0.2 mg/kg of esketamine was administered intravenously 30 minutes before the surgery ended,while the control group was given an equal volume of normal saline.Upon surgery completion,patients were transferred to PACU with endotracheal tube retained,and the time to extubation was recorded.Hemo-dynamic parameters were measured immediately after extubation and at 10 min,30 min,1 h,and 4 h thereafter.Patients' pain and sedation levels were assessed at the above time points using RASS and VAS,respectively.The incidence of EA was evaluated using the Confusion Assessment Method for the Intensive Care Unit(CAM-ICU).Observation duration in the PACU and recovery outcomes within 24 hours postoperatively were assessed via the QoR-40 and adverse events were recorded.Results Compared to those in the control group,patients in the AS group had higher HR and MAP at 10 min post-extubation,and the changes in HR and MAP over time were more stable(P<0.05).The RASS and VAS scores in the AS group were significantly lower than those in the control group at the time of extubation and all subsequent time points(P<0.05),both groups showed temporal changes in RASS and VAS scores(P<0.05),but the change process in the AS group was more stable(P<0.05).Postoperative extubation time,PACU observation duration,and adverse event rates(delirium,respiratory depression,nausea and vomiting)did not differ significantly between the two groups(P>0.05),while recovery quality was markedly better in the AS group(P<0.05).Conclusion Subanesthetic esketamine effectively alleviates pain and the incidence of EA,supports hemodynamic stability during PACU stay,and enhances recovery quality in patients undergoing laparo-scopic hernia repair,demonstrating clinical value.

OBJECTIVE To analyze the medication patterns of traditional Chinese medicine combinations for the treatment of pulmonary nodules in national patents using data mining and network pharmacology methods,providing a reference for the clinical treat-ment of pulmonary nodules.METHODS Patent data on traditional Chinese medicine compound prescriptions for the treatment of pul-monary nodules were collected from the China National Intellectual Property Administration Patent Inquiry System and the China Na-tional Knowledge Infrastructure(CNKI)patent database.Formula statistics were performed using Excel software.The Ancient and Modern Medical Case Cloud Platform was used to conduct high-frequency analysis of traditional Chinese medicine including frequency,properties and flavors,meridian tropism,efficacy categories,association rules,clustering,complex network analysis to screen out core drugs.Network pharmacology was then used to predict potential targets and pathways in patent prescriptions for the treatment of pulmo-nary nodules.RESULTS A total of 67 valid patents for the treatment of pulmonary nodules were included,involving 276 traditional Chinese medicines,with a cumulative total frequency of 859.The top five traditional Chinese medicines in terms of frequency of use were Glycyrrhiza uralensis Fisch,Astragalus membranaceus,Pinellia ternate,Curcuma zedoary and Hedyotis diffusa.These traditional Chinese medicines were primarily sweet and warm in property,primarily targeting the lung,liver,and spleen meridians,and their main effects were clearing heat,drying dampness and resolving phlegm,and promoting diuresis and reducing swelling.Association a-nalysis revealed that the top drug pairs were Scutellaria baicalensis Georgi-Pinellia ternate,Fagopyrum cymosum-Pinellia ternate,Ra-nunculus ternatus-Curcuma zedoary,Radix Angelicae Sinensis-Radix Paeoniae Alba,and Radix Angelicae Sinensis-Glycyrrhiza ura-lensis Fisch.Cluster analysis identified three drug combinations,and complex network analysis demonstrated that the core drug compo-nents were Scutellaria baicalensis Georgi,Pinellia ternate,Astragalus membranaceus,Curcuma zedoary,Fritillaria thunbergii,Fago-pyrum dibotryis,Hedyotis diffusa and Ranunculus ternatus.Network pharmacology analysis showed that the key targets for the treat-ment of lung nodules with patent prescriptions were GAPDH,IL6,TNF and so on.The core active ingredients were Baicalein,Moslosooflavone,and Norwogonin and so on.The main pathways involved were cancer pathways,lipids and arteriosclerosis,and viral carcinogenesis.CONCLUSION The inclusion of traditional Chinese medicine compound patent in this case is consistent with the eti-ology and pathogenesis of traditional Chinese medicine for treating lung nodules.Commonly used drug pairs and cluster prescriptions re-flect the flexible compatibility of traditional Chinese medicines in the treatment of pulmonary nodules,such as clearing away heat and toxic materials,resolving phlegm and eliminating swelling,regulating qi and strengthening spleen,promoting blood circulation and remo-ving blood stasis.The core drugs exert their effects on pulmonary nodules through multiple components,multiple targets and multiple pathways.

Objective Based on the secreted frizzled-related protein 2(SFRP2)-Wnt/β-catenin signaling pathway,this study explored the effect and mechanism of Cuiru Keli(CRKL)in the treatment of postpartum hypogalactia.Methods A rat model of postpartum hypogalactia was established by gavaging 2 mL of 1.6 mg/mL bromocriptine mesylate to female rats on the third day after delivery.Female rats with a delivery time difference of less than 48 hours were selected and randomly assigned to 7 groups,including a normal group(without any modeling or medication),a model group,a CRKL low-dose group of model group model rats receiving CRKL at the dose of 3 g/kg,a CRKL medium-dose group of model rats receiving CRKL at the dose of 6 g/kg,a CRKL high-dose group of model rats receiving CRKL at the dose of 9 g/kg,a positive drug group of model rats receiving domperidone at the dose of 3 mg/kg,and a negative control(NC)group of model rats receiving normal saline.Each group contained 6 rats.Except for the normal and model groups,the remaining 5 groups were continuously administered with the respective intervention drugs at the specified doses by gavage once a day for 10 days.Changes in the total litter mass of the offspring in the 7 groups within 10 days were measured,and HE staining was performed to identify pathological changes in the mammary tissue(MT).Six groups of rats(excluding the positive control group)were used to observe the pathological changes of eosinophils in pituitary tissue.ELISA was performed to determine the content of prolactin(PRL)in serum,immunohistochemical staining was used to determine the expression of prolactin receptor(PRLR)in MT,and RT-qPCR was used to determine the mRNA expression of genes related to lactation in MT.Network pharmacology and molecular docking were used to study the therapeutic effect and mechanism of CRKL on postpartum hypogalactia,particularly whether it acted through the SFRP2-Wnt/β-catenin signaling pathway.The mechanism of CRKL treatment was further validated by detecting mRNA(RT-qPCR)and protein expression(Western blot)of related pathway genes.Cell experiments were conducted using primary culture rat mammary epithelial cells(RMEC)from rat MT.RMEC were divided into four groups,including a normal group(primary culture RMEC,untreated),SFRP2 overexpression group(primary cultured RMEC treated with SFRP2 overexpression vector),SFRP2 overexpression+CRKL group(receiving treatment for SFRP2 overexpression group plus 10% drug-containing serum),and negative control group(primary culture RMEC treated with empty vector).The effect of CRKL on the expression of lactation-related genes FASN,CSN2,and GLUT1 mRNA after SFRP2 overexpression was detected by RT-qPCR.Results In this study,CRKL was administered at a dose of 3 g/kg in the CRKL low-dose group,6 g/kg in the medium-dose group,and 9 g/kg in the high-dose group(P<0.05 or P<0.01).Compared with the model group,CRKL at all doses significantly increased the total litter weight gain of the offsprings within 10 days(P<0.05 or P<0.01),and effectively increased lactation(P<0.01),the area of mammary lobules,and the size and filling of acinar cavities.CRKL at all doses also increased the number of eosinophils that secreted PRL in the pituitary gland of the postpartum hypogalactia rat model,and increased the content of PRL in the serum(P<0.05 or P<0.01).CRKL promoted the secretion and expression of PRL in postpartum hypogalactic model rats.In addition,it significantly promoted the expression of genes related to milk fat,milk protein,and lactose synthesis in MT(P<0.05 or P<0.01).Network pharmacology predicted that the Wnt signaling pathway might be a key pathway for CRKL in treating postpartum hypogalactia.The molecular docking results showed that related chemical components in CRKL had good binding ability with CCND1 and SFRP2.Compared with the model group,CRKL at all doses inhibited the expression of SFRP2 gene in vivo(P<0.01)and activated the mRNA and protein expression of CCND1 and c-Myc in the Wnt/β-catenin signaling pathway in MT(P<0.05 or P<0.01).Cell experiments showed that,compared to the normal group,SFRP2 overexpression reduced the mRNA expression of milk synthesis-related genes FASN,CSN2,and GLUT1 in RMEC(P<0.01).The CCK8 results indicated that 10% of the drug-containing serum was the effective concentration administered to cells(P<0.01).After administering drug-containing serum,the expression of the lactation-related genes FASN,CSN2,and GLUT1 were up-regulated(compared with the SFRP2 overexpression group,P<0.01).Conclusion CRKL alleviates postpartum hypogalactia through the SFRP2-Wnt/β-catenin signaling pathway.SFRP2 might be a potential new target for the diagnosis and treatment of postpartum hypogalactia.This reveals a new mechanism of CRKL in treating postpartum hypogalactia and promotes its clinical application.
