OBJECTIVES: To investigate the clinical characteristics and prognosis of chronic disseminated candidiasis (CDC) in children with acute leukemia (AL) following chemotherapy. METHODS: A retrospective analysis was conducted on children diagnosed with CDC (including confirmed, clinically diagnosed, and suspected cases) after AL chemotherapy from January 2015 to December 2023 at Fujian Medical University Union Hospital, Zhangzhou Municipal Hospital, and Quanzhou First Hospital Affiliated to Fujian Medical University. Clinical characteristics and prognosis were analyzed. RESULTS: The incidence of CDC in children with AL following chemotherapy was 1.92% (32/1 668). Among the children with acute lymphoblastic leukemia, the incidence of CDC in the high-risk group was significantly higher than in the low-risk group (P=0.002). All patients presented with fever unresponsive to antibiotics during the neutropenic period, with 81% (26/32) involving the liver. C-reactive protein (CRP) levels were significantly elevated (≥50 mg/L) in 97% (31/32) of the patients. The efficacy of combined therapy with liposomal amphotericin B and caspofungin or posaconazole for CDC was 66% (19/29), higher than with caspofungin (9%, 2/22) or liposomal amphotericin B (18%, 2/11) monotherapy. The overall cure rate was 72% (23/32). The proportion of patients with CRP ≥50 mg/L and/or a positive β-D-glucan test for more than 2 weeks and breakthrough infections during caspofungin treatment was significantly higher in the treatment failure group compared to the successful treatment group (P<0.05). CONCLUSIONS CDC in children with AL after chemotherapy may be associated with prolonged neutropenia due to intensive chemotherapy. Combination antifungal regimens based on liposomal amphotericin B have a higher cure rate, while persistently high CRP levels and positive β-D-glucan tests may indicate poor prognosis.

Since the end of 2019,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has swept the world,bringing great harm to human society and significantly increasing the health burden.Due to stron-ger infectivity,faster transmission,and higher reinfection rate of the Omicron variant,it has now replaced the Delta variant as the main epidemic strain for both imported and local outbreaks in China.Chinese Diagnosis and treatment protocol for SARS-CoV-2 infection(10th trial version)emphasizes"strengthening the protection of key popula-tions,"which includes the increasing number of immunocompromised population.These people have a high inci-dence of severe diseases and a high fatality rate after infected with SARS-CoV-2,and belong to the high-risk popula-tions of severe or critical diseases.Moreover,due to underlying diseases,these people take immunosuppressants and other related drugs chronically.The interactions between anti-SARS-CoV-2 infection treatment drugs and origi-nal drugs are complicated,thus bring significant challenges to the treatment after the SARS-CoV-2 infection.Cur-rently,there is a lack of guidelines or consensus on the diagnosis and treatment of SARS-CoV-2 infection among im-munocompromised population.Therefore,the Guangzhou Institute of Respiratory Health and National Center for Respiratory Medicine organized experts from multiple disciplines(respiratory and critical care medicine,organ transplantation,rheumatology and immunology,hematology,infection,critical care medicine,etc.)in China.Af-ter multiple rounds of discussions,13 items of recommendations are made as the reference for peers based on evi-dence-based medical evidence,so as to provide a theoretical and practical reference for the diagnosis and treatment strategies of this population.

Aim To explore whether sea-buckthorn slows down-regulation of hepatic cytochrome P450 2C(CYP 2C)in mice with liver injury by BCG vaccine(BCG)-induced via PXR/NF-κB pathway.Methods The mouse model of liver injury was induced by a single tail vein injection of BCG 125 mg·kg-1 for hepatitis B research,and the mice were randomly di-vided into control group,BCG group,BCG+sea-buckthorn granules(SG)group(gavage 50,100,200 mg·kg-1,twice a day),BCG+PCN group(intraper-itoneal injection 100 mg·kg-1,once a day).The levels of serum transaminase and TNF-α and IL-1β in liver tissue were detected by ELISA.The nuclear pro-tein expression NF-κB p65 and the total protein expres-sion of pregnane X receptor(PXR),CYP2C in liver were detected by Western blot.Liver pathological changes were observed by HE staining.Results Sea-buckthorn inhibited overexpression of TNF-α,IL-1βand NF-κB p65,alleviated the down-regulation of CYP2C and PXR protein expression,and improved liv-er pathology and serum transaminase in a dose-depend-ent manner.After intervention with PCN,a mouse specific agonist of PXR,it was similar to the high dose group of SG.Conclusion Sea-buckthorn slows down-regulation of CYP2C in mice with liver injury by BCG-induced via PXR/NF-κB pathway.

OBJECTIVE: To examine the bone proportional measurement standard on the chest and abdomen of modern women. METHODS: The height, weight and distances of bone proportional measurement chest and abdomen of 101 young females were measured. The height was divided by 75 to calculate the data of bone proportional measurement, and compared with the national standard published in 2006 and the ancient literature of Miraculous Pivot: Gudu. RESULTS: The bone proportional distances between two nipples and two coracoid processes of women were 8 cun and 12 cun respectively, which were in line with the 2006 national standard. The bone proportional distance from navel to superior margin of pubic symphysis (Qugu) was 6.5 cun, which was consistent with the ancient literature of Miraculous Pivot: Gudu. The bone proportional distance from suprasternal fossa to the middle point of xiphisternal synchondrosis (Qigu) was less than 9 cun, while the bone proportional distance from Qigu to navel was more than 8 cun, resulting in the ratio less than 9︰8. The bone proportional distance from suprasternal fossa to the middle point of xiphoid process was 9 cun, corresponding to the ratio of 9︰8 when comparing with the measurement from the middle point of xiphoid process to navel. CONCLUSION The bone proportional distance measurement between two nipples and two coracoid processes of women should follow the 2006 national standard, and the bone proportional distance measurement from navel to superior margin of pubic symphysis should follow the standard of Miraculous Pivot: Gudu. The middle point of xiphisternal synchondrosis should be replaced by the middle point of xiphoid process.

Objective: To analyze the clinical characteristics, treatment response, and prognosis of newly diagnosed symptomatic multiple myeloma (MM) patients with systemic light chain amyloidosis (AL) . Methods: The clinical data of 160 patients with newly diagnosed MM treated at the First Affiliated Hospital of Soochow University from January 1, 2017 to October 31, 2018, were retrospectively analyzed. According to the histopathological biopsy results of bone marrow, skin, and other tissues, the patients were divided into two groups according to whether amyloidosis was combined or not, namely, the MM+AL group and the MM group. The clinical characteristics and treatment responses of the two groups were compared. Results: Among the 160 patients with newly diagnosed MM, there were 42 cases in the MM+AL group and 118 cases in the MM group. In terms of clinical features, the involved light chain and non-involved light chain (dFLC) in the MM+AL group was significantly higher than that in the MM group (P=0.039) . After induction treatment, the MM+AL group had a higher overall response rate (85.7%vs 79.7%, P<0.05) and higher excellent partial response (76.2%vs 55.1%, P<0.05) . After a median follow-up of 26 (0.25-41) months, there was no significant difference in the progression free survival and overall survival (OS) between the two groups (P>0.05) . The OS of patients in autologous hematopoietic stem cell transplantation group was better than that in non transplantation group (P<0.05) .The prognosis of patients with cardiac involvement in the MM+AL group was significantly worse than that in the MM group and MM+AL group without cardiac involvement (P<0.001) , with a median OS of only 13 months. Conclusion: The differential diagnosis between the MM+AL and MM groups requires histopathology, particularly for patients with significantly increased dFLC. The overall remission rate of patients in MM+AL group after 4 courses of induction chemotherapy was higher than that in MM group. The prognosis of patients with cardiac involvement in MM+AL group was poor.

Effective supplementation of probiotics can be beneficial to intestinal health, but in situ analysis of probiotics activity has rarely been reported. In this study, by coupling fluorescein 5-isothiocyanate (FITC) and 5(6)-carboxytetramethylrhodamine N-succinimidyl ester (5(6)-TAMRA-SE) with D-lysine, two fluorescent D-amino acids (FDAAs) probes were obtained: green probe (fluorescein-D-lysine, FDL) and red probe (TAMRA-D-lysine, TDL). Then, we tried to label the three kinds of probiotics, Lactobacillus acidophilus (LA), Lactobacillus casei (LC) and Veillonella atypica (VA) in vitro. FDAAs was applied to the labeling of intestinal flora in mice, and a method was established to investigate the oral survival rate of three commonly used probiotics. All animal experiments were approved by the Animal Ethics Committee of Guangzhou University of Chinese Medicine. The results show that the two synthetic FDAAs can be non-toxic and 100% for the in vitro labeling of the three probiotics. Known by FDAAs two-step labeling of oral probiotics, the high survival rate of LA was 92.30% ± 1.67%. The survival rates of VA and LC are similar, 84.13% ± 4.06% and 82.27% ± 2.43%, respectively. This study can quickly compare the changes of colonization survival rate of different probiotics in vivo, provide theoretical support for the in situ colonization activity of probiotics in the intestine, and guide the rational drug use of clinical probiotics.

Saposhnikovia divaricata is a commonly used bulk medicinal plant. To explore the key enzyme genes and their expression in the biosynthesis of chromone and coumarin, the key active components, we carried out transcriptome sequencing(Illumina HiSeq) and bioinformatics analysis for the 1-year-old(S1) and 2-year-old(S2) plants of S. divaricata. A total of 40.8 Gb data was obtained. After the sequence assembly via Trinity, 110 732 transcripts and 86 233 unigenes were obtained, which were aligned and annotated with NR, Swiss-Prot, GO, KEGG, and PFAM. Daucus carota and S. divaricata had the highest sequence homology. KEGG pathway enrichment showed that the differentially expressed genes were mainly enriched in plant hormone signal transduction, phenylpropanoid biosynthesis, and flavonoid biosynthesis pathways. A total of 27 differentially expressed unigenes, including 13 enzyme genes, were identified in the pathways related to the synthesis of active ingredients in S. divaricata. Compared with S1 plant, S2 plant showed up-regulated expression of PAL, BGL, C4H, 4CL, CYP98A, CSE, REF, and CCoAOMT and down-regulated expression of CHS, CAD, and COMT. HCT and POD had both up-regulated and down-regulated unigenes. Among them, PAL, C4H, 4CL, BGL, and CHS can be used as candidate genes for the synthesis of the active ingredients in S. divaricata. The four key enzyme genes were verified by RT-qPCR, which showed the results consistent with transcriptome sequencing. This study enriches the genetic information of S. divaricata and provides support for the identification of candidate genes in the biosynthesis of secondary metabolites.
