Objective To explore the influence factors and predictors of treatment response after adrenocorticotropic hormone(ACTH)in infantile epileptic spasms syndrome(IESS).Methods A retrospective analysis was conducted on 80 cases of IESS infants(50 males and 30 females)who were diagnosed and treated with ACTH in Chengdu Women's and Children's Central Hospital from January 2016 to December 2020.Patients were divided into effective group(n=39)and ineffective group(n=41)based on their response of ACTH treatment after 28 days,and their clinical data including the patients'basic information,etiology,treatment programmer,per-and post-treatment Kramer scores of electroencephalogram(EEG)hypsarrhythmia severity and so on,were collected to compare and analyze between the two groups.A modified Poisson regression model was constructed to discover predictors of outcome,and the receiver operating characteristic(ROC)curves were used to assess the prognosis evaluation of the positive predictive value.Results The ages at seizure onset ranged from one month and seven days to one year and nine months.Seizure types included simple epileptic spasms in 66 cases and combined with other types(focal and secondarily generalized seizures)in 14 cases.Thirty-two cases had been given anti-seizure medications(ASMs)before ACTH treatment.The median Kramer scores per-treatment and at 14 days post-treatment were 10.0(8.3,12.0)and 6.0(4.0,7.0),respectively.After ACTH treatment,39(48.8%)cases were effective.Compared with the effective group,the ineffective group had significantly higher proportion of abnormal perinatal conditions,unknown aetiology with normal development,ASMs given before ACTH treatment,the dosages of ACTH greater than 2 U/(kg·d),combinations of two or more ASMs,poor control,and still seizure attack after ACTH treatment of 14 days(P<0.05).Additionally,the Kramer scores after ACTH treatment of 14 days in the ineffective group were also significantly higher(P<0.05).The modified Poisson regression model showed that there were significant statistic differences between the two groups on ASMs given before ACTH treatment(RR=0.546,95%CI 0.357-0.833,P=0.005)and Kramer scores of hypsarrhythmia severity(RR=0.701,95%CI 0.620-0.792,P<0.001),while there were no significant differences between the two groups in term of ages,gender,perinatal conditions,etiologies,seizure types,Kramer scores before treatment,time lag between onset and treatment,duration of ACTH treatment,kinds of ASMs combination.ROC curve analysis showed that only Kramer scores at 14 days after ACTH treatment could predict the treatment response with sensitivity and specificity of 92.7%and 84.6%,respectively,with Youden index of 0.773.The area under the ROC curve was 0.930(95%CI 0.873-0.987,P<0.001)and the cut-point of the score was 6,indicating that the higher the Kramer scores at 14 days after ACTH treatment,the worse the treatment response.The treatment response rate would reduce by about 30.0%if the Kramer score increased by one point.Conclusion ASMs given before ACTH treatment may influence the treatment response.Kramer scores greater than 6 at day 14 after ACTH treatment may be used as a predictor of treatment response after ACTH in IESS patients.

Objective:To investigate the effect and mechanism of Chaihu Jia Longgu Mulitang （CJLM） on hippocampal NOD-like receptor protein 3 （NLRP3）inflammasome pathway in rats with depression. Method:Sixty male SD rats were randomly divided into a normal group，a model group， a MCC950 （1 mg·kg^-1） group， and high- （13 g·kg^-1）， medium- （6.5 g·kg^-1）， and low-dose （3.25 g·kg^-1） Chaihu Jia Longgu Mulitang groups， with 10 rats in each group．The depression model was induced by isolation combined with chronic unpredictable mild stimulation（CUMS） in rats except for those in the normal group. Rats were treated correspondingly for 21 days by intraperitoneal injection in the MCC950 group and gavage in other groups. The normal group and the model group received an equal volume of normal saline. The depression-like behaviors of rats were observed by sucrose preference test （SPT） and novelty-suppressed feeding test. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of interleukin-1β （IL-1β） and IL-18 in the hippocampus of depressed rats. Western blot was used to detect the protein levels of NLRP3， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， and Caspase-1. Result:Compared with the normal group， the model group showed decreased sucrose preference rate （P<0.01）， prolonged novelty-suppressed feeding time （P<0.01）， enhanced protein expression of NLRP3，ASC， and caspase-1 （P<0.05， P<0.01）， and elevated expression of IL-1β and IL-18 （P<0.01）. Conclusion:CJLM can alleviate depression-like behaviors in CUMS-induced model rats， and the underlying mechanism is related to the inhibition of the NLRP3 inflammasome pathway．

Purpose: This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. Methods: An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. Results: In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. Conclusions In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.

Objective:To study the soil physical and chemical properties， microorganisms， and metabolites in different culture environments of Gastrodia elata， so as to provide scientific basis for subsequent cultivation of G. elata in multiple environments. Method:The tubersphere soil of G. elata cultured in different environments was collected for analyzing the soil nutrients， microbial numbers， and metabolite differences using the agrochemical method， plate-count method， and gas chromatography-time-of-flight mass spectrometry （GC-TOF-MS）-based non-targeted metabonomic approach. Result:The analysis of soil physical and chemical properties revealed the highest soil moisture， pH， available potassium， and available phosphorus in the spinney and the highest electrical conductivity， total nitrogen， alkali-hydrolyzable nitrogen， and organic matter in the pinewood. As demonstrated by the quantitative analysis of soil microorganisms， the cultivable microorganisms were bacteria， actinomycetes， and fungi， with the bacterial population and total microbial biomass in the spinney and the number of fungi and actinomycetes in the barren slope detected to be the largest. The ratio of bacteria to fungi （B/F value） in the pinewood was the highest， while that in the barren slope was the lowest. The results of metabonomic research demonstrated that the compositions and quantities of soil metabolites in the spinney （Z group）， pinewood （S group）， and barren slope （HD group） varied. Through comparisons between S and Z groups， between HD and Z groups， as well as between HD and S groups by orthogonal partial least squares discriminant analysis （OPLS-DA）， 18， 35， and 24 differential metabolites were separately screened out， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis yielded 5， 9， and 13 metabolic pathways. There existed a significant causal relationship of the soil physical and chemical properties and microbial numbers with the metabolites. Conclusion:The soil physical and chemical properties， microbial numbers， and metabolite changes differed significantly in different culture environments of G. elata， which were sorted by the suitability in a descending order as follows： spinney > pinewood >barren slope. The soil physical and chemical properties and microbial numbers are the crucial factors driving changes in soil metabolites， suggesting that regulating the soil physical and chemical characteristics and microbial characteristics in the culture environment is an important mechanism for maintaining the G. elata-soil-microbial symbiotic system.

Objective To analyze the changes in the endemic situation of schistosomiasis in national surveillance sites of Hunan Province, so as to provide scientific basis for the development of the schistosomiasis elimination programme in the province. Methods According to the requirements of the National Guidelines for Schistosomiasis Surveillance in China (2014 version), a total of 41 national schistosomiasis surveillance sites were assigned in all disease-endemic counties (districts) across Hunan Province. During the period between 2015 and 2019, Schistosoma japonicum infections were monitored in local residents, mobile populations and livestock, and snail status was monitored. The morbidity due to schistosomiasis and snail status was compared between years. Results The sero-prevalence of S. japonicum infections was 2.57% and 1.56% in local residents and mobile populations in national surveillance sites of Hunan Province from 2015 to 2019, respectively, and the sero-prevalence appeared a tendency towards a decline over years. A higher sero-prevalence rate of S. japonicum infections was seen in men than in women (P < 0.01). During the 5-year study period, the sero-prevalence rate of human S. japonicum infections appeared a tendency towards a decline in the marshland, embankment, inner embankment and hilly types of endemic areas over years. There were 44 and 19 egg -positives detected in local residents and 5 and 1 egg-positives in mobile populations in 2015 and 2016 respectively. A total of 9 346 domestic animals were monitored from 2015 to 2019, and 6 egg-positives were detected in 2015 and 2016 (all were bovine). A total of 0.155 billion m² settings were surveyed from 2015 to 2019, and the mean density of living snails appeared a tendency towards a decline over years, with a 45.79% reduction in 2019 as compared to 2015. However, no S. japonicum infections were identified in snails during the 5-year period. A total of 1 469 mixed snail samples were detected using loop-mediated isothermal amplification (LAMP), and 6 positive snail samples were identified in 2015 (one sample) and 2017 (5 samples). Conclusions The overall endemic situation of schistosomiasis appears a tendency towards a decline in Hunan Province, and the prevalence of S. japonicum infections is at a low level in humans and livestock; however, there is still a risk of schistosomiasis transmission. Improvements of health education, intensification of schistosomiasis examinations in mobile populations and reinforcement of the surveillance-response system is required to consolidate the achievements of schistosomiasis control in Hunan Province.
