Objective To assess the academic influence of schistosomiasis control and research institutions in China. Meth-ods The papers (including original articles and reviews) pertaining to schistosomiasis in Science Citation Index Expanded (SCIE)of Web of Science(WOS)during the period from 2002 to 2012 were searched. The number of published papers,h index and citation frequencies of the papers of Chinese institutes and authors were analyzed by a bibliometric method,and the academic influences of the institutes and authors were assessed according to the number of published papers and h index. In addition,the scientific knowledge network map was plotted by using the CiteSpace II software to analyze the inter-institution academic collabora-tion network. Results From 2002 to 2012,totally 610 papers pertaining to schistosomiasis were published by Chinese scholars, accounted for 16.7%of the published papers in global,and the quantity increased year by year. The number of published papers and h index of the National Institute of Parasitic Diseases(NIPD),China Center for Disease Control and Prevention(China CDC) were 114 and 27,respectively,both of which were ranked at the first position among all the Chinese institutes,and in the academ-ic collaboration network,the NIPD played a central and dominate part. Xiao-Nong Zhou with the h index of 17 became the out-standing academic leader in the research field of schistosomiasis control. Conclusions Both number of published papers in SCIE and h index of the Chinese institutes for schistosomiasis control are far inferior to the leading institutions in the world. It suggests that when strengthening the research and control of schistosomiasis,we should pay an attention to the output and sharing of the control experience and achievements.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is an extremely rare, indolent skin malignancy that can be difficult to distinguish from autoimmune disease-associated panniculitides. Here, we describe a 12-year-old boy who was diagnosed at age 7 years with dermatomyositis with classical manifestations, including poikiloderma, Gottron’s sign, and symmetric muscle weakness. Recently, the boy presented multiple subcutaneous nodules and fever. Histopathological examination and immunohistochemical staining revealed coexistence of SPTL. To our knowledge, this is the first case of dermatomyositis accompanied with SPTL. This case alert clinical physicians of the possibility of SPTL should be considered when a patient with dermatomyositis has new lesions presenting as nodules and unknown fever.

Objective:To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement.Methods:From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed.Results:Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement ( P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions:NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

Liver failure (LF) is a great trouble to the majority of patients due to its severe onset, many complications, difficult treatment, poor prognosis and other characteristics. This disease is liver injury caused by infection, hepatotoxic substances, autoimmunity, circulation disorders and other factors. It is a group of common clinical symptoms mainly manifested by coagulation disorders, jaundice, hepatic encephalopathy, ascites, and so on. In traditional Chinese medicine, it falls under the categories of "tympanites", "jaundice" and other diseases. At present, the research progress of Western medicine in the treatment of LF is slow, and its clinical application effect is still not ideal. In contrast, traditional Chinese medicine has a long history in the treatment of this disease, with over thousands of years of clinical practice and verification. It is characterized by exact efficacy and fewer side effects. The pathological mechanism of LF is extremely complex, involves a variety of signaling pathways, and is mainly related to inflammation, oxidative stress, liver fibrosis, cell apoptosis and other processes. In recent years, many studies have shown that traditional Chinese medicine can intervene in the occurrence and development of LF by mediating relevant signaling pathways in vivo, but there is still a lack of relevant summary. Therefore, this review summarized several signaling pathways related to the intervention of traditional Chinese medicine in LF by referring to and sorting out relevant literature worldwide, including nuclear factor kappa B (NF-κB), mitogen-activated protein kinase (MAPK), phosphatidylin-ositol-3-kinase/protein kinase B (PI3K/Akt), transforming growth factor-β/ drosophila mothers against decapentaplegic proteins (TGF-β/Smads), and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1), and elaborated the specific mechanism of their intervention in LF. This paper aims to provide practical and effective pathways and corresponding mechanisms for the treatment of LF by traditional Chinese medicine, and to provide new ideas and a theoretical basis for the clinical treatment of LF and further scientific research.

OBJECTIVE To provide reference for basic analysis of the pharmacodynamic substance in Stahlianthus involucratus. METHODS Overall 24 SD male rats were randomly divided into blank group (purified water), and administration group (ethanol extract of S. involucratus, 15.75 g/kg, calculated by crude drug), with 12 rats in each group. They were given drug liquid/purified water intragastrically, twice a day, every 6-8 h, for consecutive 3 days. After medication, the blood, urine and fecal samples were collected from two groups of rats. UPLC-Q-Exactive-MS technology was used to identify the chemical constituents in the ethanol extract of S. involucratus, and metabolites in the blood, urine and fecal of rats after intragastrical administration of the ethanol extract of S. involucratus. Multivariate statistical analysis was employed to screen various serum metabolites. Metabolic pathways were analyzed by MetaboAnalyst 5.0 platform. RESULTS A total of 38 chemical constituents were identified from the ethanol extract of S. involucratus, including fourteen prototype components and three metabolites identified from 5 urine samples, nine prototype components identified from fecal samples, and ten prototype components and one metabolite identified from serum samples. A total of 71 differential metabolites were screened from two groups of rat serum samples, of which 44 differential metabolites, such as ferulic acid, glycyrrhizin, were up-regulated and 27 differential metabolites, such as arachidonic acid, phenylacetylglutamine, were down-regulated. The 71 differential metabolites were mainly enriched in 11 metabolic pathways, including phenylalanine metabolism, linoleic acid metabolism, arachidonic acid metabolism, and tryptophan metabolism. CONCLUSIONS Ferulic acid, liquiritigenin, isofraxidin and formononetin may be the material basis that directly exert pharmacological effects of S. involucratus. S. involucratus may exert anti-inflammatory effects by affecting metabolic pathways, including arachidonic acid metabolism and tryptophan metabolism.

Objective :
To investigate the sex difference of the effects of chronic pregnancy stress on depression-like behavior in offspring adolescent mice and whether the amygdala is involved in mediating depression-like behavior and its possible mechanism.
Methods :
Male and female of C57BL /6J mice were put in cage together.Pregnant mice were randomly divided into normal control group ( CON group) and chronic pregnancy stress group ( CPS group) .The day of delivery was recorded as post-natal day(PND0) .The offspring of different groups were divided into Female group and Male groupaccording to sex,respectively.From PND35,the depressive-like behavior of off- spring was monitored in different groups.Morphological structure of basolateral amygdala (BLA) cone neurone was observed by Golgi-Cox staining,and apoptosis of BLA neurone was detected by TUNEL.Serum corticotrophin-relea- sing hormone ( CRH) was detected by ELISA.The level of protein associated with amygdala mammalian target of rapamycin (mTOR) and phosphorylated mammalian target of rapamycin [p-mTOR ( Ser2448) ]was detected by Western blot.
Results :
Depression-like behavior was appeared in different sexual offspring by chronic pregnancy stress,and there was an interaction between chronic pregnancy stress and gender.In the forced swimming test,the immobility time of offspring in the CPS group prominently increased(Female: P<0. 05,Male: P<0. 001) .Interest- ingly,compared with female offspring ,despairing behavior of male offspring was much more clearly observed in CPS group(P<0. 05) .Compared with offspring of CON group,the rate of sucrose preference was significantly re- duced in the female offspring of CPS group(P<0. 05) ,while no obvious difference was observed in the male off- spring.Compared with the CON group,the density of neuronal dendrite branches in the BLA of offspring mice in the CPS group decreased(Female: P<0. 01,Male : P<0. 01) and the degree of neuronal apoptosis increased( Fe- male: P<0. 001,Male : P <0. 001) ,the expression level of p-mTOR in amygdala of offspring mice in CPS group significantly decreased(Female: P<0. 001,Male: P<0. 001) .Chronic pregnancy stress increased the serum CRH level of offspring mice(P<0. 001) ,and the gender had significant influence on serum CRH level,the serum CRH level of female in CPS group was higher than that of male(P<0. 05) .
Conclusion
Chronic pregnancy stress leads to depression-like behavior in offspring adolescent mice,and the depression-like behavior has gender differences. In addition,chronic pregnancy stress leads to dendrite atrophy and apoptosis of BLA neurons in offspring mice,and the mechanism may be that the activation of mTOR in the amygdala of offspring mice is inhibited.CRH may be in- volved in mediating sex differences in depression-like behavior and BLA neuron damage in offspring induced by chronic pregnancy stress.

Objective :
To explore the mechanism of hippocampal corticotropin-releasing hormone ( CRH) receptor type 1 ( CRHR1 ) in chronic stress-induced learning and memory impairment in early aged mice.
Methods:
C57BL /6J mice aged 12 -14 months were divided into two groups according to gender,and then divided into wild type (WT) group and hippocampal CRHR1 conditional gene knockout (KN) group according to genotype.Mice in each group were randomly divided into control group and stress group,and the stress group was subjected to chronic unpredictable stress ( CUS ) for 30 days. Genotyping of mice was performed using polymerase chain reaction ( PCR) ,agarose gel electrophoresis and real-time fluorescence quantitative PCR (RT-qPCR) .The new object rec- ognition experiment and Morris Water maze measured learning and memory ability.Golgi-Cox staining was used to observe damage to hippocampal neuronal dendrites. The protein expressions of target protein of rapamycin (mTOR) ,p-mTOR (Ser2448) ,ribosomal protein S6 kinase ( p70S6K) and p-p70S6K ( Thr389 / Thr412 ) were detected by Western blot.Serum levels of corticotropin releasing hormone ( CRH) were measured by ELISA.
Results :
Compared to mice without chronic stress,the cognitive coefficient of WT stress groups decreased after chron- ic stress,and the difference was statistically significant (P <0. 05) ,while there was no significant difference in cognitive coefficient of KN stress groups before and after chronic stress.Compared with the WT stress group,the escape latency of the WT control group was shortened (P<0. 05) ,and the number of crossing the platform and tar- get quadrant increased (P <0. 01) ,and there was no significant difference in the KN groups above. Compared with the WT control group,the WT stress group had a significant reduction in the neuronal complexity in the hipp- ocampal CA1,CA3 and DG regions (P <0. 05) and significant reductions in the expression of p-mTOR and p- p70S6K in the hippocampus (P<0. 05) .There was no significant difference in the expression of p-mTOR between the KN stress group and the KN control group (P>0. 05) ,except that the expression of p-mTOR in the hippocam- pus of the female group decreased (P<0. 05) .In addition,the serum level of CRH in the stress group was higher than that in the control group (P<0. 01) .
Conclusion
Hippocampal CRHR1 regulates learning and memory im- pairment and neuronal dendrite damage in early aged mice induced by chronic stress.The mechanism may be that high levels of CRH induced by chronic stress cannot bind to CRHR1 receptor,thereby enhancing the expression of down-regulated mTOR / p70S6K signaling pathway.
