Daochisan is a pediatric famous classical formula in traditional Chinese medicine（TCM） specializing in clearing the heart， disinhibiting water and enriching Yin， which has been inherited and developed by medical experts of successive generations. The formula can be traced back to Xiaoer Yaozheng Zhijue written by QIAN Yi from Song dynasty， and most of the later-developed Daochisan（Daochitang） is based on this formula with additions and subtractions. So as to promote the literature excavation of this formula， this paper conducts a thorough textual research and analysis of the composition， processing， preparation methods， clinical applications of Daochisan based on a systematic collation of relevant ancient and modern literature in the method of bibliometrics. A total of 127 pieces of data involving 86 antient TCM books were collected. Statistical analysis showed that the drug origin of Daochisan is basically clear， we suggest that Rehmanniae Radix is the root tuber of Rehmannia glutinosa of Scrophulariaceae， Akebiae Caulis is the dry stem of Akebia quinata of Lardizabalaceae， Glycyrrhizae Radix et Rhizoma is the dry root and stem of Glycyrrhiza uralensis of legume， bamboo leaf is the dry leaves of Phyllostachys nigra var. henonis of gramineous plants. Four herbs are recommended to use its raw products. The key information of the dosage and decocting method is supposed to be "4.13 g each of raw Rehmanniae Radix， raw Glycyrrhizae Radix et Rhizoma， Akebiae Caulis， adding 300 mL of water， and then adding 4.13 g of bamboo leaf， decocting together to 150 mL， taking warmly after meal". Daochisan has the effect of clearing the heart and enriching Yin， disinhibiting water and relieving stranguria， and is widely used in treating symptoms such as heart vexed hotness， hydrodipsia and reddish complexion. Modern studies have showed that Daochisan are frequently used in treating oral ulcer， herpetic stomatitis， urinary tract infection， herpes zoster and other diseases. The above research results can provide scientific reference for the future development and research of Daochisan.

Objective To conduct hazard vulnerability analysis(HVA)in a blood bank,aimed to identify high-risk e-vents and optimize emergency management measures.Methods The risk event evaluation index system was established by referring to the Kaiser model and the situation of Guangzhou Blood Center,and risk events were ranked by risk matrix and Borda count.Results The top five events with the highest risk values identified by Kaiser model were information system e-mergencies(39.61％),extreme weather(38.03％),major public sentiment(37.86％),public health events(37.37％)and policy changes(37.24％).The results of risk matrix and Borda count revealed 1 extremely high-risk indicator as information system emergency,5 high-risk indicators with the highest risk being major public sentiment,11 medium-risk indicators with the highest risk being major medical disputes and 1 low-risk indicator as external fires.Conclusion Conducting HVA in combination with the actual situation of blood banks can effectively identify high-risk events and provide theoretical basis for improving emergency management measures.

This paper discussed the historic evolution of Juanbitang and similar decoctions， clarified the historic development of Yangshi Juanbitang and Chengshi Juanbitang， and probed into the key information of the meaning， original plants， processing methods， and modern dosage and usage of Chengshi Juanbitang. A total of 267 pieces of relevant information were collected from ancient traditional Chinese medicine （TCM） books， among which 53 pieces of effective data were included in this study. The results showed that both Chenshi Juanbitang and Yangshi Juanbitang were originated from Duhuo Jishengtang recoded in the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang）. According to the standard of "1 qian roughly equals 3.73 g" in the measurement system of the Qing Dynasty， we suggest Chenshi Juanbitang is composed of 3.73 g Notopterygii Rhizoma et Radix， 3.73 g Angelicae Pubescentis Radix， 3.73 g Gentianae Macrophyllae Radix， 11.19 g Angelicae Sinensis Radix， 11.19 g Mori Ramulus， 2.61 g Chuanxiong Rhizoma， 1.87 g Cinnamomi Cortex， 1.87 g stir-fried Glycyrrhizae Radix et Rhizoma， 7.46 g Piperis Kadsurae Caulis， 2.98 g Olibanum， and 2.98 g Aucklandiae Radix， which should be decocted with 600 mL water to reach a volume of 300 mL. The decoction should be taken 3 times a day before meals. Juanbitang， a classical formula specialized for treating impediment diseases， has the effects of dispelling wind， removing dryness， and alleviating impediment to relieve pain. It can be used for treating vexing pain in body， spasm of nape and back， and heaviness in waists and legs. Modern studies have shown that Juanbitang can be used for treating rheumatoid arthritis， knee osteoarthritis， and periarthritis of shoulder. The above results served as a reference for the future development of Juanbitang.

Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)pre-sents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains unclear.In this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2％dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG group.We detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,respectively.Meanwhile,DR3-overexpressing MNK-3 cells and 2％ DSS-induced Rag1-/-mice were used for verification.The results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal barrier.Simultaneously,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage indepen-dently of the adaptive immune system.We additionally confirmed that paeoniflorin-conditioned me-dium(CM)restored the expression of tight junctions in Caco-2 cells via coculture.In conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 signaling pathway.

【Objective】 To apply the spatial distribution analysis based on ArcGIS software, which has been applied widely in other fields, so as to analyze the intended locations for whole blood donation. 【Methods】 After a random stratified sampling was conducted among blood donors in the 17 donation sites during August 1st, 2021- July 30th, 2022, their intended blood donation locations were collected by an e-questionnaire. Addresses of donors′ intended donation locations were derived for GCJ-02 coordinates form and transformed by pandas module of Python to WGS84 coordinates, which further loaded to ArcGIS Arcmap module using Grouping Analysis for 17 median centers. The addresses of 17 blood donation sites in Guangzhou Blood Center were transformed to WGS84 coordinates and loaded to ArcGIS Arcmap module using the same methods for 3 ring buffer analysis. The criterion for judging whether the two were " matched" was whether the intended blood donation sites were covered by or adjacent to the 3 ring buffer zone of the existing blood donation sites. 【Results】 Of the 17 potential sites obtained from the spatial distribution analysis of 40 523 valid addresses of donors, 8 sites were covered or adjacent to the buffer of the existing donation sites, while the other 9 sites were far away from the existing donation sites. 【Conclusion】 By analyzing the spatial distribution of donors′ intended donation addresses, we can find out the service needs of donors for donating blood conveniently, which can provide basis for further blood donation service optimization.

B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is characterized by genetic alterations with high heterogeneity. Precise subtypes with distinct genomic and/or gene expression patterns have been recently revealed using high-throughput sequencing technology. Most of these profiles are associated with recurrent non-overlapping rearrangements or hotspot point mutations that are analogous to the established subtypes, such as DUX4 rearrangements, MEF2D rearrangements, ZNF384/ZNF362 rearrangements, NUTM1 rearrangements, BCL2/MYC and/or BCL6 rearrangements, ETV6-RUNX1-like gene expression, PAX5alt (diverse PAX5 alterations, including rearrangements, intragenic amplifications, or mutations), and hotspot mutations PAX5 (p.Pro80Arg) with biallelic PAX5 alterations, IKZF1 (p.Asn159Tyr), and ZEB2 (p.His1038Arg). These molecular subtypes could be classified by gene expression patterns with RNA-seq technology. Refined molecular classification greatly improved the treatment strategy. Multiagent therapy regimens, including target inhibitors (e.g., imatinib), immunomodulators, monoclonal antibodies, and chimeric antigen receptor T-cell (CAR-T) therapy, are transforming the clinical practice from chemotherapy drugs to personalized medicine in the field of risk-directed disease management. We provide an update on our knowledge of emerging molecular subtypes and therapeutic targets in BCP-ALL.

OBJECTIVE：To study the effect s of Bifidobacterium combined with L-carnitine on intestinal flora of dysbacteriosis diarrhea model rats. METHODS ：Totally 30 SD rats were randomly divided into blank control group ，model group ，probiotics group（Bifidobacterium triple viable enteric coated capsules 70 mg/mL），L-carnitine group （L-carnitine injection 50 mg/mL）and L-carnitine+probiotics group （L-carnitine injection 50 mg/mL+Bifidobacterium triple viable enteric coated capsules 70 mg/mL）. Except for blank control group ，the rats in other groups were given 50 mg/mL clindamycin phosphate intragastrically （2 mL/rat， once a day ，for 4 consecutive days ）to establish the model of dysbacteriosis diarrhea. On the 5th day of the experiment ，the rats in administration groups were given corresponding drugs intragastrically ，blank control group and model group were given equal volume of normal saline intragastrically ；with the dosage volume of 1 mL/rat，once a day ，for consecutive 7 days. The general situation of rats in each group was observed during the experiment. The feces of normal control group and model group at the end of the modeling and the feces of the rats in administration group after the last administration were collected for genomic DNA extraction，polymerase chain reaction amplification ，library construction and high-throughput sequencing. After processing ，the effective data were analyzed by operational taxonomic unitsclustering and species annotation ，as well as Alpha and Beta diversity of compared with blank control group ，grade 1 feces and grade 2feces were found in model group. The diversity and richness of intestinal flora ，the ratio of Firmicutes/Bacteroidetes and zhongjuanwang7@163.com the abundance of probiotics such as Lactobacillus， Bifidobacterium and Ackermann were significantly decreased （P＜0.05），while the abundance of pathogenic bacteria such as Enterococcus was significantly increased （P＜0.05）. At the end of the recovery period ，compared with model group ，the activity，fecal morphology and color of rats in probiotics group ，L-carnitine group and L-carnitine+probiotics group returned to normal，and the diversity and richness of intestinal flora had no significant difference （P＞0.05）. However ，the abundance of Lactobacillus in intestinal tract was increased to a certain extent ，and the abundance of Ackermann in intestinal tract of rats in L-carnitine+probiotics group was significantly increased （P＜0.05）. CONCLUSIONS ：Although Bifidobacterium combined with L-carnitine have no significant effect on improving the diversity and richness of intestinal flora in dysbacteriosis diarrhea model rats，it could increase the abundance of probiotics to a certain extent.

【Objective】 To obtain HTLV prevalence data among blood donors in mainland China through meta-analyze, and provide reference for relevant policies. 【Methods】 The literature concerning HTLV prevalence among blood donors in mainland China before April 15, 2021 in CNKI, Wanfang and Pubmed was searched. According to the inclusion criteria and exclusion criteria, relative literature within recent 10 years was screened and then analyzed by meta-analysis using R3.3. 【Results】 A total of 69 articles were included, covering 22 provincial administrative regions, with a total sample size of 7 435 501 cases. 535 cases were HTLV positive, of which 491 centred on three coastal provinces as Fujian, Guangdong and Zhejiang, and 44 scattered in 11 other provincial administrative regions. The pooled prevalence of HTLV in blood donors in Fujian, Guangdong and Zhejiang provinces were 3.25/10 000(95%CI 1.91/10 000~4.58/10 000), 0.13/10 000(95%CI 0.09/10 000~0.17/10 000) and 0.33/10 000(95%CI 0.06/10 000~0.61/10 000), respectively. Subgroup analysis showed that the pooled prevalence of HTLV in Fujian blood donors decreased since December 2015. 【Conclusion】 Blood donors in mainland China present low HTLV prevalence, mainly distributed in three coastal provinces as Fujian, Guangdong and Zhejiang. The sample size tested increased greatly since HTLV screening for blood donors was popularized nationwide in blood stations in December 2015, the infection rate of HTLV in Fujian, however, did not increase as expected.

【Objective】 To investigate the impact of ceasing mutual blood donation on voluntary blood donation in Guangzhou. 【Methods】 The data of blood donation from July 2016 to December 2019 (42-month before and after the official cease of mutual blood donation) in the Blood Collection and Supply System of Guangzhou Blood Center, including whole blood donations and apheresis platelets donations, were collected for interrupted time series analysis by month. Blood donors who donated (either whole blood or platelets) during 2016 were followed up until December 31, 2019, and the re-donation rate was analyzed by Chi-square test, t test and logistic regression analysis. 【Results】 The results showed that ceasing mutual blood donation had a significantly positive effect on the increase of platelet donations, but had no significant effect on whole blood donation. In 2016, whole blood donations and platelet donations were mainly voluntary (86.4% and 60.8%, respectively). In comparison of voluntary blood donation, the overall blood deferral rate(by dual assays) of mutual blood donation was higher (P<0.01), but the difference diminished as they donated twice or more. The re-donation rate of blood donors (mutual non-remunerated, voluntary, or both) all increased after the ceasing of mutual blood donation (mutual non-remunerated, : 4.7% vs 4.0%, χ²=29.8, P<0.01; voluntary: 24.8% vs 9.9%, χ²=17295.3, P<0.01; both: 36.3% vs 28.1%, χ²=29.3, P<0.01). The re-donation rate of mutual platelet donors decreased after the ceasing of mutual blood donation, but the number of voluntary platelet donors increased. 【Conclusion】 The ceasing of mutual blood donation was in favour of voluntary blood donation in Guangzhou since various means had been previously adopted by Guangzhou Blood Center to create a long-term mechanism of voluntary blood donation. The number of voluntary blood donors has increased, and the clinical use of blood has been further guaranteed.

【Objective】 To investigate the changes of platelet, white blood cell, red blood cell counts, Hb and PCV before and after plateletpheresis donation. 【Methods】 10 444 platelet donors who donated platelet from Aug 1, 2019 to Jul 31, 2020 were selected as subjects, among which first-time donors were selected as control group and donors who donated twice or more as donation group. After matching gender and age using Propensity Score Matching method in the two groups, the changes of platelet, white blood cell, red blood cell counts, Hb and PCV of platelet blood donors were compared by t test. 【Results】 There were a slight increase in Plt (t=-6.651, P<0.05), a decrease in WBC (t=2.312, P<0.05), a decrease in hemoglobin(t=4.643, P<0.05), and no change in RBC (t=1.439, P>0.05) and in PCV (t=0.030, P>0.05) after plateletpheresis donation. 【Conclusion】 Plateletpheresis donation has an effect on some peripheral blood parameters, but within the normal reference range.
