Objective:To investigate the clinical features and prognostic factors of primary tonsil lymphoma(PTL).Methods:The clinical data of 41 patients diagnosed with PTL and treated in the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2022 were collected and retrospectively analyzed.Their clinical features and prognostic factors were analyzed.Results:All the 41 patients were newly diagnosed with PTL,and the median age of onset was 58(19-85)years.Among them,19 patients started with pharyngeal pain,12 patients presented with dysphagia,8 patients presented with pharyngeal mass,and 2 patients presented with blurred articulation.The most common pathological type was diffuse large B-cell lymphoma(24 cases,58.54％).All patients received chemotherapy,and 3 patients were combined with hematopoietic stem cell transplantation.Among 41 patients,11(26.83％)achieved complete response,14(34.15％)achieved partial response,and the total response rate was 60.98％(25/41).The median follow-up time was 37(6-107)months,the 5-year overall survival(OS)rate was 70.81％and 5-year progression-free survival(PFS)rate was 66.20％.Univariate analysis showed that B symptoms,Ki-67,β2-MG and IPI score had significant effects on PFS and OS of patients(all P＜0.05).Multivariate analysis showed that IPI score was an independent risk factor for PFS and OS of patients(P＜0.05).Conclusion:The clinical manifestations of PTL lack specificity,and the prognosis is relatively good.Most patients can achieve long-term survival after treatment.IPI score is related to the prognosis.

Alcoholic liver disease(ALD), a major cause of chronic liver disease worldwide, poses a serious threat to human health. Despite the availability of various drugs for treating ALD, their efficacy is often uncertain, necessitating the search for new therapeutic approaches. Traditional Chinese medicine polysaccharides have garnered increasing attention in recent years due to their versatility, high efficiency, and low side effects, and they have demonstrated significant potential in preventing and treating ALD. Emerging studies have suggested that these polysaccharides exert their therapeutic effects through multiple mechanisms, including the inhibition of oxidative stress and the regulation of lipid metabolism, gut microbiota, and programmed cell death. This review summarizes the recent research progress in the pharmacological effects and regulatory mechanisms of traditional Chinese medicine polysaccharides in treating ALD, aiming to provide a scientific basis and theoretical support for their application in the prevention and treatment of ALD.

italic>Acanthopanax senticosus is one of the genuine regional herb in Northeast China. In this study, we identified the germplasm resources of commercial A. senticosus samples based on atpI and atpB_rbcL according to the previous chloroplast genome sequencing results, and determinated the content of syringin by HPLC to evaluated the quality of commercial samples. A total of 80 A. senticosus samples were collected from 47 cities in 24 provinces. DNA was extracted to amplify the products of atpI and atpB_rbcL by PCR. The results showed that 7 haplotypes (H2, H5, H8, H10, H12, H14, H23) were formed by the combined analysis of the two gene fragments. H2 from Yichun in Heilongjiang, Shangzhi in Harbin, Suihua in Heilongjiang, Fushun in Liaoning, Benxi in Liaoning, Changbai in Jilin and Jingyu in Jilin were the dominant genotype, representing 58.75% of the total samples. H14 and H23 were the unique haplotypes of the producing area. It is speculated that the commercial A. senticosus samples with haplotypes of H14 and H23 are from Raohe, Shuangyashan, Heilongjiang and Mingshui, Suihua, Heilongjiang, respectively. HPLC analysis indicated that the content of syringin in 73.96% of the samples met the Pharmacopoeia standards. There was a significant difference in the content of syringin among the samples, ranging from 0.003 7% to 0.524 5%, with a difference of 0.520 8%, indicating that the quality of the samples in the market of A. senticosus was uneven. However, there were no significant differences in the contents of syringin in the commercial A. senticosus among different haplotypes. The content of syringin in the haplotype H23 in the market sample is relatively high, so it may be a germplasm with better quality. This study researched the germplasm resources and medicinal materials quality of commercial A. senticosus samples and will help guide the commercial circulation, reasonable medication of A. senticosus, and the screening of excellent germplasm.

Eleutherococcus senticosus is one of the Dao-di herbs in northeast China. In this study, the chloroplast genomes of three E. senticosus samples from different genuine producing areas were sequenced and then used for the screening of specific DNA barcodes. The germplasm resources and genetic diversity of E. senticosus were analyzed basing on the specific DNA barcodes. The chloroplast genomes of E. senticosus from different genuine producing areas showed the total length of 156 779-156 781 bp and a typical tetrad structure. Each of the chloroplast genomes carried 132 genes, including 87 protein-coding genes, 37 tRNAs, and 8 rRNAs. The chloroplast genomes were relatively conserved. Sequence analysis of the three chloroplast genomes indicated that atpI, ndhA, ycf1, atpB-rbcL, ndhF-rpl32, petA-psbJ, psbM-psbD, and rps16-psbK can be used as specific DNA barcodes of E. senticosus. In this study, we selected atpI and atpB-rbcL which were 700-800 bp and easy to be amplified for the identification of 184 E. senticosus samples from 13 genuine producing areas. The results demonstrated that 9 and 10 genotypes were identified based on atpI and atpB-rbcL sequences, respectively. Furthermore, the two barcodes identified 23 genotypes which were named H1-H23. The haplotype with the highest proportion and widest distribution was H10, followed by H2. The haplotype diversity and nucleotide diversity were 0.94 and 1.82×10~(-3), respectively, suggesting the high genetic diversity of E. senticosus. The results of the median-joining network analysis showed that the 23 genotypes could be classified into 4 categories. H2 was the oldest haplotype, and it served as the center of the network characterized by starlike radiation, which suggested that population expansion of E. senticosus occurred in the genuine producing areas. This study lays a foundation for the research on the genetic quality and chloroplast genetic engineering of E. senticosus and further research on the genetic mechanism of its population, providing new ideas for studying the genetic evolution of E. senticosus.

OBJECTIVE: To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies. METHODS: Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members. Then, peripheral blood samples of the proband and her family members were collected, and all exons of FGA, FGB and FGG and their flanks were amplified by PCR and sequenced to search for gene mutations. RESULTS: The proband had normal APTT and PT, slightly prolonged TT, reduced level of Fg activity (Clauss method). The Fg of the proband's aunt, son and daughter all decreased to varying degrees. The results of thromboelastogram indicated that Fg function of the proband and her family members (except her son) was basically normal. Gene analysis showed that there were 6233 G/A (p.AαArg35His) heterozygous mutations in exon 2 of FGA gene in the proband, her children and aunt. In addition, 2 polymorphic loci were found in the family, they were FGA gene g.9308A/G (p.AαThr331Ala) and FGB gene g.12628G/A (p.BβArg478Iys) polymorphism, respectively. The proband was injected with 10 units of cryoprecipitate 2 hours before delivery to prevent bleeding, and no obvious bleeding occurred during and after delivery. CONCLUSION Heterozygous mutation of 6233G/A (p.AαArg35His) of FGA gene is the biogenetic basis of the disease in this family with congenital dysfibrinogenemia.

ObjectiveTo observe the effect of Liuwei Dihuangtang （LWDHT） on depression-like behaviors of rats with diabetes mellitus and depression （DD） and explore its mechanism. MethodThe diabetes mellitus （DM） model was induced by the high-fat diet and tail vein injection of low-dose streptozotocin （STZ） in 50 male Sprague-Dawley rats of SPF grade. Then the DD model was induced by chronic unpredictable mild stress （CUMS） for 28 days in DM rats. Fifty DD rats were randomly divided into model group， fluoxetine group （10 mg·kg^-1·d^-1）， and low-， medium-， and high-dose LWDHT groups （3.375， 6.75， 13.5 g·kg^-1·d^-1）， with 10 rats in each group. Another 10 healthy rats were assigned into a control group and received normal saline by gavage. After four weeks of drug intervention， the forced swimming assay was carried out to assess the depression-like behaviors of rats. The expression levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， interleukin-4 （IL-4）， and interleukin-10 （IL-10） in the anterior cingulate cortex （ACC） were detected by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence was used to detect the expression of myelin basic protein （MBP） in ACC and the co-localization of ionized calcium-binding adapter molecule 1 （Iba1） with intracellular microtubule-associated protein 1 light chain 3 （LC3）. The protein expression levels of MBP， myelin proteolipid protein （PLP）， myelin oligodendrocyte glycoprotein （MOG）， Beclin-1， LC3， p62， and microglia （MG） phenotypic protein-related inducible nitric oxide synthase （iNOS）， and arginase 1 （Arg1） were detected by Western blot. ResultCompared with the control group， the model group showed shortened swimming time and prolonged immobility time （P<0.01）. Compared with the model group， the medium- and high-dose LWDHT groups showed reduced immobility time （P<0.05， P<0.01）. Compared with the control group， the model group showed decreased protein expression of MBP， PLP， and MOG in the ACC region （P<0.01）. Compared with the model group， the fluoxetine group and the medium- and high-dose LWDHT groups showed up-regulated protein expression of MBP， PLP， and MOG （P<0.05， P<0.01）. Compared with the control group， the model group showed decreased MBP fluorescence intensity in the ACC region （P<0.01）. Compared with the model group， the fluoxetine group and the medium- and high-dose LWDHT groups showed increased MBP fluorescence intensity in the ACC region （P<0.05， P<0.01）. Compared with the control group， the model group showed increased expression of iNOS （P<0.01） and slightly increased Arg1 protein expression. Compared with the model group， the medium- and high-dose LWDHT groups and the fluoxetine group showed down-regulated iNOS expression and up-regulated Arg1 protein expression （P<0.05， P<0.01）， but there was no significant difference between the fluoxetine group and the medium-，high-dose LWDHT groups. Compared with the control group， the model group showed increased expression levels of proinflammatory factors IL-1β and TNF-α in the ACC region （P<0.01） and slightly increased expression levels of anti-inflammatory factors IL-4 and IL-10. Compared with the model group， the fluoxetine group， and the medium- and high-dose LWDHT groups showed down-regulated expression of IL-1β and TNF-α （P<0.05， P<0.01） and up-regulated expression of IL-4 and IL-10 （P<0.05， P<0.01）. Compared with the control group， the model group showed reduced expression levels of Beclin-1 and LC3Ⅱ （P<0.01） and increased expression level of p62 （P<0.01）. Compared with the model group， the fluoxetine group and the medium- and high-dose LWDHT groups showed up-regulated Beclin-1 and LC3Ⅱ expression （P<0.01） and down-regulated p62 expression （P<0.01）. Compared with the control group， the model group showed decreased LC3⁺Iba1⁺ cells in the ACC region （P<0.01）. Compared with the model group， the fluoxetine group and the medium- and high-dose LWDHT groups showed increased LC3⁺Iba1⁺ cells （P<0.05， P<0.01）. ConclusionLWDHT can alleviate the depression-like behaviors in DD rats presumedly by promoting MG autophagy， regulating MG phenotypic changes， and increasing MG clearance of myelin sheath fragments. Meanwhile， MG phenotypic transformation also inhibits ACC inflammation in DD rats， improves the local microenvironment of oligodendrocyte proliferation and differentiation， and ultimately promotes the repair and remyelination of damaged myelin sheath.
