Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ2 = 30.905, P = 0.000), educational level- (χ2 = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ2 = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ2 trend = 22.717, P = 0.000) and increased with education levels (χ2 trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ2 = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ2 = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.

ObjectiveMetabolomics was used to reveal the mechanism of Aconiti Lateralis Radix Praeparata(ALRP) in attenuating toxicity by processing from the aspects of amino acid metabolism, oxidative stress and energy metabolism by analyzing multiple metabolic pathways. MethodTwenty-four rats were randomly divided into control group, raw group and processed group, 8 rats in each group. The raw and processed group were given with 0.64 g·kg-1 of raw ALRP and processed ALRP respectively every day, the control group was given with an equal amount of normal saline once a day. After continuous administration for 7 days, the urine, serum and heart tissue of rats were collected. Pathological examination of the heart was carried out using hematoxylin-eosin(HE) staining, and the activities of lactate dehydrogenase(LDH) and creatine kinase-MB(CK-MB) in serum and cardiac tissues were detected by microplate assay and immunoinhibition assay. The effects of ALRP on rat heart before and after processing were compared and analyzed. Ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to perform urine metabolomics analysis, and multivariate statistical analysis was used to screen for differential metabolites related to ALRP in attenuating toxicity by processing, and pathway enrichment analysis was carried out to explore the processing mechanism. ResultHE staining showed that no obvious pathological changes were observed in the heart tissue of the control group, while obvious infiltration of inflammatory cells such as plasma cells and granulocytes was observed in the heart tissue of the raw group, indicating that the raw ALRP had strong cardiotoxicity. There was no significant difference in HE staining of heart tissue between the processed group and the control group, indicating that the toxicity of ALRP was significantly reduced after processing. Compared with the control group, the activities of LDH and CK-MB were significantly increased in serum and heart tissue of the raw group, and those were significantly decreased in serum and heart tissue of the processed group, suggesting that the myocardial toxicity of processed ALRP was reduced. A total of 108 endogenous differential metabolites associated with the raw ALRP were screened using multivariate statistical analysis in positive and negative modes, of which 51 differential metabolites were back-regulated by the processed ALRP. Biological analysis of the key regulatory pathways and associated network changes showed that the pathways related to toxicity of ALRP mainly included tryptophan metabolism, arginine and proline metabolism, phenylalanine metabolism, aminoacyl-tRNA biosynthesis, alanine, aspartate and glutamate metabolism, etc. The metabolic pathways related to the attenuation of processed ALRP mainly included aminoacyl-tRNA biosynthesis, tryptophan metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and caffeine metabolism. ConclusionThe processing technology of ALRP in Guilingji can significantly attenuate the cardiotoxicity of raw products, the mechanism mainly involves amino acid metabolism, oxidative stress and energy metabolism, which can provide experimental bases for the research related to the mechanism of toxicity reduction of ALRP by processing and its clinical safety applications.

[Objective]To explore if the enhanced recovery after surgery (ERAS) protocol for pregnant women with gestational diabetes mellitus (GDM) who are undergoing elective cesarean delivery could cause perioperative glycemic abnormalities and heighten the risk of neonatal hypoglycemia.[Methods]A retrospective analysis was conducted on a cohort of pregnant women with singleton pregnancies who underwent elective cesarean sections and received ERAS between May 1,2022,and October 31,2023,at the Third Affiliated Hospital of Sun Yat-sen University. A total of 150 patients were included in this study,comprising the GDM group (n=75) and the non-GDM group (n=75). The study included pregnant women with good glycemic control (GDM) and maternal age (18-30 years;30-35 years;35-40 years;>40 years),BMI (<18.5 kg/m2;18.5-24.9 kg/m2;25-30 kg/m2;>30 kg/m2),and gestational age (within 7 days). We used these criteria to match 1∶1 non-GDM women as the control group. After administering preoperative oral carbohydrates,we observed the trends of maternal glycemic changes,including hyperglycemia and hypoglycemia,at any time of the day. We also evaluated the incidence of hypoglycemic low Apgar scores in newborns,abnormal pH values in blood gases,and the rate of transfer to the pediatric unit immediately after delivery.[Results]No significant difference was observed in fasting blood glucose levels on the day of surgery between the two groups of pregnant women[(4.4±0.5) mmol/L vs. (4.3±0.5) mmol/L,t=1.395,P=0.165]. The blood glucose peak was reached 30 minutes after consuming 300 mL (42.6 g of low-dose carbohydrate) of a light drink[(7.2±0.9) mmol/L vs. (6.4±0.8) mmol/L,t=5.773,P<0.001],with a subsequent decline in blood glucose levels. At the 120-minute mark,blood glucose had returned to the pre-oral carbohydrate level. The blood glucose levels in GDM groups was significantly higher than those in the non-GDM group (P<0.005). Although the incidence of hyperglycemia was significantly higher in the GDM group than in the non-GDM group at the 30-minute peak blood glucose level after oral carbohydrate intake,and the difference was statistically significant (17.3% vs. 1.3%,x2=11.354,P<0.001),severe hyperglycemia (≥10 mmol/L) did not occur. The incidence of hypoglycemia was not significantly higher in neonates in the GDM group than in the non-GDM group (22.7% vs. 28%,x2=0.564,P=0.453). The incidence of neonatal hypoglycemia in the GDM group was not significantly elevated in comparison to the non-GDM group after adjusting for age and BMI (Model 1),primiparity and gestational week of delivery (Model 2),hypertensive disorders of pregnancy (Model 3),cesarean section indications,time of cesarean section,and intraoperative hemorrhage (Model 4),and neonatal weight (Model 5).[Conclusion]In GDM patients with excellent glycemic control,an ERAS regimen with a low oral dose of carbohydrates prior to elective cesarean section does not increase the risk of preoperative serious hyperglycemia in mothers,nor does it increase the incidence of neonatal hypoglycemia.
