[Expedited program and utilization for anticancer drug approval in China and the United States].

Objective: To systematically summarize and comparatively analyze the development, establishment and usage of oncology drugs speedy review approaches in China and in the United States between 2012 and 2021. Methods: Based on National Medical Products Administration (NMPA) and Food and Drug Administration (FDA) websites, the development and current status of the speedy review approaches were consulted and summarized. Approved oncology drugs in China and in the United States (87 in China, 118 in the United States) over the past decade were analyzed using chi-square test for group comparison. Results: Five speedy approaches have been established in China and in the United States, three of which are the same, priority review, conditional approval or accelerated approval and breakthrough therapy. The rest two are special review and approval, special examination and approval in China, and fast track and real-time oncology review in the United States. Compared to the United States, speedy review approaches in China set up late (1992 vs. 2005). The overall utilization rates of the oncology drugs speedy review approaches were similar between the China and United States (90.8% vs. 92.4%, P=0.800) in the previous 10 years, and priority review have highest utilization rates in both China and the United States without significant group difference (77.0% vs. 82.2%, P=0.381); relatively low utilization rates of conditional approval (31.0% vs. 44.9%, P=0.041) and breakthrough therapy (2.3% vs. 50.0%, P＜0.001) were seen in China. 52.9% of new drugs applied for special examination and approval in China and 40.7% of new drugs applied for fast track in the United States. Overall, the priority review both in China and the United States are stable, with a similar average annual utilization rate (84.8% vs. 83.7%); accelerated approval and breakthrough therapies in the United States fluctuate wildly, but the situation is tending towards stability in the last 3 years. Conclusions: Both China and the United States have established a relatively complete accelerated review system, with an overall utilization rate over 90%; China's accelerated review started late, although the overall utilization rate is close to that of the United States. The utilization rates of conditional approval and breakthrough therapy are still relatively low. Flexible usage of speedy review approaches, gaining regulatory recognition to use alternative endpoints, achieving real-time review and guidance are keys to accelerate new drug development in China.

Probiotics/prebiotics/synbiotics and human neuropsychiatric outcomes: an umbrella review.

The neuropsychiatric effects of probiotics, prebiotics, and synbiotics have been gaining attention since the rise of microbial-gut-brain axis research. Nevertheless, some of the findings are inconsistent, and few studies have analysed the similarities and differences in the neuropsychiatric effects of the three comprehensively. To reveal the respective neuropsychiatric effects of probiotics, prebiotics, and synbiotics and synthesise the similarities and differences among the three effects, 47 meta-analyses with 12 types of neuropsychiatric results were integrated under an umbrella review. Probiotics, prebiotics, and synbiotics intake might all be associated with improvements in some neuropsychiatric outcomes, including neuropsychological test outcomes (probiotic and prebiotic), hepatic encephalopathy outcomes (probiotic, prebiotic, and synbiotic), instant memory in patients with Alzheimer's disease (probiotic), depressive symptoms (probiotic, prebiotic and synbiotic), mood states and psychiatric distress (probiotic), overall mental health (probiotic), neurological function (probiotic), brain-derived neurotrophic factor (BDNF) concentration (probiotic and synbiotic), and Pittsburgh Sleep Quality Index (PSQI) score (probiotic). All three are similar in that the intake of probiotics, prebiotics, and synbiotics might be associated with improvements in hepatic encephalopathy outcomes and depressive symptoms, both probiotic and synbiotic intake might be associated with elevated BDNF concentrations, and both probiotic and prebiotic intake might be associated with improved neuropsychological test results. The difference between the three is that the neuropsychiatric effects of probiotics might be more widespread and be reflected in the fact that probiotic intake might also be associated with improvements in mood states and psychiatric distress, overall mental health, neurological function, Alzheimer's disease patients' instant memory, and PSQI score. Probiotics might be the best and most promising option for improving neuropsychiatric outcomes. In the future, in addition to requiring more high-quality meta-analyses, further preclinical studies are needed to explore specific relevant mechanisms and determine true causal relationships.

[Current status and prospects of health hazards database for chemical hazards].

In order to facilitate technical personnel related to occupational health and safety production to search, obtain, and master information on the hazard classification and health effects of chemical hazards, this article surveyed 14 commonly used foreign databases and 9 commonly used domestic databases, analyzed the characteristics, main content, scope of application, and network resources of each database, and considered the development of database for occupational health hazard of chemical hazards.

[Clinical characteristics of POEMS syndrome initially diagnosed as increased extravascular volume load: a single-center retrospective study].

POEMS syndrome is a rare plasma cell dysplasia. Its clinical manifestations include polyneuropathy, monoclonal protein, increased extravascular volume load, endocrinopathy, organomegaly and skin changes. The complex and atypical symptoms at presentation make early diagnosis challenging due to multiple system involvement. Peripheral neuropathy, limb numbness, is the most common initial symptom of this disease. However, case reports of increased extravascular volume load are rare. This article collected and analyzed the clinical data of two groups of patients with different initial symptoms (increased extravascular volume load and limb numbness). The clinical characteristics and treatment responses were summarized.

[Swertiamarin ameliorates 2, 4, 6-trinitrobenzenesulfonic acid-induced colitis in mice by inhibiting intestinal epithelial cell apoptosis].

OBJECTIVE: To investigate the mechanism by which swertiamarin (STM) ameliorates CD-like colitis in mice. METHODS: A Caco-2 cell model of TNF-α-stimulated apoptosis was established and divided into three groups: Con, TNF-α and STM, and the effects of STM on apoptosis and barrier function were assessed by Tunel staining, western blotting, immunofluorescence, and transepithelial electric resistance (TEER). A mouse model of 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) -induced CD-like colitis was established to assess the effects of STM on colitis, intestinal barrier function and epithelial cell apoptosis. The regulatory role of the PI3K/AKT pathway in STM-induced resistance to intestinal epithelial cell apoptosis was investigated in both the cell model and mouse models. RESULTS: TUNEL staining showed that in Caco-2 cells with TNF-α stimulation, STM treatment significantly reduced the percentage of TUNEL-stained cells (P<0.05). STM obviously reduced TNF-α-induced enhancement of cleaved-caspase 3 and Bax expressions (P<0.05), increased Bcl-2 expression (P<0.05), protected intestinal barrier integrity and function by restoring transepithelial electrical resistance (TEER) of the cells, promoted normal localization and expressions of the tight junction proteins (ZO1 and claudin 1) (P<0.05), and inhibited the expression of pro-inflammatory factors (IL-6 and CCL3) (P<0.05) in TNF-α-stimulated Caco-2 cells. In the mouse models, STM significantly alleviated TNBS-induced CD-like colitis and intestinal barrier dysfunction (P<0.05) as shown by improved weight loss, lowered Disease Activity Index (DAI) score and inflammation score, reduction of IL-6 and CCL3 release, and restoration of intestinal barrier permeability, colonic TEER, bacterial translocation, and localization and expressions of the tight junction proteins. Mechanistically, STM inhibited the expressions of p-PI3K and p-AKT in both the cell model and mouse model(P<0.05), and treatment with 740Y-P (a PI3K/AKT pathway activator) significantly attenuated the inhibitory effect of STM on TNF-α-induced apoptosis in Caco-2 cells (P<0.05). CONCLUSION: STM inhibits intestinal epithelial cell apoptosis at least in part by suppressing activation of the PI3K/AKT pathway to ameliorate intestinal barrier dysfunction and colitis in mice.

[Comparison of horizontal plane auditory spatial discrimination abilities and testing methods in patients with symmetrical sensorineural hearing loss].

Objective: To evaluate auditory spatial discrimination capabilities in patients with mild to moderately severe symmetrical sensorineural hearing loss (SNHL) and to compare the impact of different psychophysical testing methods on Minimum Audible Angle (MAA) and test duration. Methods: A total of 105 symmetrical SNHL patients aged from 18 to 60 years old were enrolled from April to July 2023, including 56 males and 49 females. They were divided into three groups based on PTA: mild, moderate, and moderately severe hearing loss, with 35 individuals in each group. Additionally, a control group of 35 individuals with normal hearing was tested, including 18 males and 17 females. Participants underwent four distinct psychophysical discrimination tests: the block up-down, 1-up/1-down, 1-up/2-down, and 1-up/3-down procedures. We recorded the MAA and test duration for each. We employed repeated measures of ANOVA to compare the MAA and test duration across different methods and groups, and Pearson's correlation to assess the relationship between MAA and degree of hearing loss. Results: MAA of sound localization in patients with symmetrical SNHL was significantly positively correlated with the degree of hearing loss (r=0.59, P<0.01). Significant deterioration in MAA was observed as hearing loss progressed to the moderate level (PTA≥35 dBHL, P<0.01). The testing methods significantly influenced MAA and testing duration (F=24.02, P<0.01; F=75.56, P<0.01) and the 1-up/1-down method was the quickest, averaging only (0.69±0.32) mins. Conclusions: The horizontal plane auditory spatial discrimination abilities in patients with symmetrical SNHL is impaired progressively with increasing hearing loss, notably beyond moderate hearing loss levels. Different psychophysical methods influence both MAA and test duration, the quicker 1-up/1-down method is recommended for assessing MAA in symmetrical SNHL patients.

[The distribution of biomarkers for Behcet syndrome and their clinical relevance in real-world studies].

Objective: To explore the distribution of different biomarkers for Behcet's syndrome (BS) and their correlation with distinct clinical phenotypes of BS patients in real-world studies. Methods: This study was a retrospective cross-sectional study. A total of 483 patients diagnosed with BS in the Department of Rheumatology and Immunology, Peking University People's Hospital from 2019 to 2022 were enrolled. The baseline information and clinical features of the patients were recorded at their first diagnosis and tested the level of HLA-B51, several auto-antibodies, antistreptolysin-O(ASO), immune globulin, complement in blood serum and interleukin-6 (IL-6). Logistic regression was used to analyze the correlation of biomarkers and phenotypes. Results: Among BS patients, the number of positive cases for HLA-B51, anti-endothelial cell antibody (AECA), antinuclear antibodies (ANA) and ASO was 129, 115, 79 and 54, respectively. The positive rate of other biomarkers was less than 5.0%. About 12.6% of patients with BS had an increased level of IgA (n=61), and 10.8% of patients had an increased level of IgG (n=52). About 41.0% of patients had increased levels of IL-6 (n=198), and 6.4% of patients had decreased levels of IgM (n=31). About 11.2% of patients had decreased levels of C3 (n=54), and 6.0% of patients had decreased levels of C4 (n=29). Elevated IgA was a risk factor for the articular phenotype of BS (OR=2.652, P=0.011). Decreased complement C4 was a risk factor for the neurological phenotype of BS (OR=3.594, P=0.039). Positive ASO was a risk factor for the gastrointestinal phenotype of BS (OR=2.578, P=0.041). Elevated IL-6 was a risk factor for the ocular phenotype of BS (OR=7.560, P=0.016). Conclusion: HLA-B51 and AECA are common biomarkers in BS. Elevated IgA, decreased complement C4, positive ASO, and elevated IL-6 are risk factors for different phenotypes of BS.

[Effects of low dose skin tissue derived peptides on the function and collagen expression of keloid fibroblasts].

This study aims to investigate the effects of the skin tissue derived peptides on proliferation, apoptosis, migration and collagen expressions in keloid fibroblasts. From January 2015 to January 2017, patients with hypertrophic scar who underwent surgical excision in department of plastic surgery of Nanjing maternal and child health hospital were included in this retrospective study. Four peptides were selected from the differential peptides between human hypertrophic scar and normal skin tissue. They were named as peptide deregulated in hypertrophic scar 2-5 (PDHPS2-5). Bioinformatics and functional analysis were performed. A low dose of 10 µmol/L of four peptides were respectively added to the culture medium of human primary keloid fibroblasts for 24 h. Cell counting kit-8 (CCK-8) were used to detect the changes in cell viability. Cell apoptosis was detected by flow cytometry. Cell migration ability was checked by Transwell chamber. The protein expressions of collagen COL1A2 (Collagen type I alpha 2) and the myofibroblast marker gene ACTA2 (Actin alpha 2) were analyzed by Western blot. The results showed that bioinformatics prediction analysis revealed that peptide PDHPS4 has the longest half-life and the highest thermal stability. Compared with the control group, low dose of four peptides had no significant effect on the survival rate and apoptosis of keloid fibroblasts tested by CCK-8 assay and flowcytometry. Transwell analysis showed that one peptides (PDHPS5) can significantly inhibit the cell migration ability (The optical density value in Control is 0.81±0.11, in PDHPS5 is 0.27±0.03, t=8.61, P=0.001). Western blot analysis showed that four peptides (PDHPS2, PDHPS3, PDHPS4, PDHPS5) can significantly inhibit the protein expressions of COL1A2 (The relative protein band intensity in Control is 1.02±0.02, in PDHPS2 is 0.21±0.04, in PDHPS3 is 0.26±0.03, in PDHPS4 is 0.53±0.04, in PDHPS5 is 0.73±0.04, t=31.38, 38.54, 18.88, 11.07 respectively, all P value are less than 0.01). Three peptides (PDHPS2, PDHPS3, PDHPS5) can significantly inhibit the protein expressions of ACTA2 (The relative protein band intensity in Control is 1.02±0.02, in PDHPS2 is 0.64±0.05, in PDHPS3 is 0.77±0.06, in PDHPS5 is 0.47±0.07, t=12.08, 6.38, 14.06 respectively, all P value are less than 0.01). In conclusion, the differentially expressed peptides in human hypertrophic scar tissue can affect the function of keloid fibroblasts and collagen expressions to varying degrees. Among them, two peptides (PDHPS2,PDHPS3) significantly inhibit the protein expressions of COL1A2 and ACTA2. The peptide PDHPS5 has high stability, significantly suppresses cell migration, and reduces the protein expressions of COL1A2 and ACTA2, which may provide a new strategy for scar prevention and treatment.

[Prevalence of dentinal hypersensitivity and related factors in Chinese urban adults].

Objective: To assess the prevalence of dentinal hypersensitivity (DH) and related factors in urban adults in China. Methods: The study was designed as an observational, cross-sectional epidemiological study carried out in adults aged 18-69 years old in seven cities (Beijing, Shanghai, Wuhan, Chengdu, Xi'an, Guangzhou, and Harbin) of China. The study was conducted from March 2021 to May 2023. Patients were required to complete a questionnaire regarding the subjects' socio-economic factors, dietary behavior, oral health behavior and personal antecedent factors. DH was clinically diagnosed by judging whether the tooth cold air stimulation provoked DH or not, and recorded by investigator pain rating Schiff score. Compare the findings of six cities (Harbin excluded) with a similar study conducted in 2008. Results: In total, 11 622 subjects from seven cities in China participated the study. Fifty two point two percent (6 072/11 622) of subjects reported DH in questionnaire, 36.7% (4 266/11 622) of subjects reported experiencing DH in response to cold air stimulation for at least one study tooth. Risk factors including age, sex, city, toothbrush method and acid reflux showed marked associations with DH (P<0.05). The prevalence of DH of urban residents in six cities (Harbin excluded) was 33.7% (3 335/9 882), higher than that in 2008 [29.7%(2 354/7 939)]. Conclusions: Overall, DH was common among urban adults in China and the prevalence increased in recent years. Better understanding of DH and its associated factors should be considered in its prevention and management by dental professionals.

Ningxiang pig-derived Enterococcus hirae HNAU0516 ameliorates postweaning diarrhoea by promoting intestinal health and modulating the gut microbiota in piglets.

Early weaning-induced stress precipitates diarrhoea, significantly curtailing the growth performance of piglets. A pivotal contributor to this postweaning affliction is the emergence of gut bacterial dysbiosis. Enterococcus hirae, a promising probiotic, has indicated unclear effects and mechanisms on intestinal health. In this study, we investigated the effects and underlying mechanisms of oral supplementation with Ningxiang pig-derived Enterococcus hirae HNAU0516 orally supplementation on the gut bacterial community, immune response and gut barrier function in piglets. 21 d age Duroc × (Landrace × Yorkshire) piglets with a similar BW were randomly allocated to two groups. The Enterococcus hirae HNAU0516 administration group was inoculated orally with Ningxiang pig-derived Enterococcus hirae HNAU0516 throughout the trial period. Conversely, the control group received the same volume of physiological saline. Our findings revealed that Enterococcus hirae HNAU0516 supplementation effectively reduced diarrhoea rates of piglets (P = 0.010). Notably, this probiotic promoted intestinal development and enhanced intestinal barrier function. It also showed potential anti-inflammatory properties. Furthermore, Enterococcus hirae HNAU0516 supplementation significantly remodelled the colonic microbiota and increased the production of acetate (P = 0.007). In conclusion, our study highlights that Ningxiang pig-derived Enterococcus hirae HNAU0516 improves postweaning diarrhoea by promoting intestinal development, enhancing intestinal barrier function, decreasing intestinal permeability, modulating intestinal microbiota, and increasing short-chain fatty acids production.

[The imaging appearances of stapical footplate fistula related to inner ear malformation].

Objective: To summarize the HRCT and MRI appearances of stapical footplate fistula related to inner ear malformation (SFF-Re-IEM). Methods: The HRCT and MRI materials of 48 cases (53 ears) SFF-Re-IEM were retrospectively analyzed. Among them, 25 SFF-Re-IEM ears were confirmed by surgery. Their CT and MRI findings including associated IEM type, internal auditory canal (IAC) malformation, tympanic fluid, its density and signal features, and accompanied labyrinthitis were recorded. Results: Among 48 cases (53 ears) with SFF-Re-IEM, 17 ears with incomplete partition type Ⅰ, accounting for 32.1%, 13 ears with common cavity for 24.5%, 13 ears with cochlear aplasia for 24.5%, 7 ears with cochlear dysplasia Ⅱ for 13.2%, and 3 ears with Mondini for 5.7%,were found respectively. 94.3% of them were associated with a defect or dysplasia in the found of the IAC. They were divided into 4 types according to the intact of the stapical footplate and accompanied CSF otorrhea: 22 ears were diagnosed as the stapical footplate leaking, of them, 2 ears might come from the stapical footplate bony defect, 6 ears were from the stapical footplate hernia. 1 ear belonged to the peristapical footplate leaking. 30 ears with the isolated the stapical footplate hernia were another found. The bony defect in 2 ears with the stapical footplate bony defect were not presented on CT and MRI.The focal bony defect of the affected stapical footplate of 36 ears with the stapical footplate hernia were demonstrated, which presented the hemispherical protruding into the tympana, the soft-tissue density on CT, and CSF-like signal on the MR heaved-T2WI images. Among 22 ears with the stapical footplate leaking, their imaging appearances varied from the different amount of the leaking CSF. Besides the focal bony defects of the affected stapical footplates, there were much more CSF-like density or signal in the ipsilateral tympanic cavity in 17 affected ears connecting with the vestibule through the defect area. In the CSF leaking ears with less CSF leaking in 5 ears, the CSF-like cysts like SFH were shown on the stapical footplate defect area, but their outer edges were irregular, and the CSF-like signal scattering in the tympanic cavity did not connect with the protruding cysts at the stapical area. Conclusion: The variable appearances of the SFF-Re-IEM ears based on the different subtypes are its characteristic HRCT and MRI appearances. This is helpful for the SFF-Re-IEM diagnosing to grasp its imaging features.

Enhancing acute stroke assessment: evaluating the clinical utility of the "Real" one-stop-shop scan protocol combining brain computed tomography perfusion and head-and-neck computed tomography angiography using a 512-slice detector computed tomography scanner.

AIM: To assess the efficiency and diagnostic value of the "real" one-stop-shop protocol integrating the computed tomography angiography (CTA) sequence of the head and neck into the computed tomography perfusion (CTP) acquisition using a 512-slice detector CT scanner in patients who suffered from acute ischemic stroke. MATERIALS AND METHODS: This prospective study included 100 patients suspected of acute ischemic stroke. The patients were randomly divided into two groups: the control group (n=50) who underwent the traditional protocol (brain CTP and head-and-neck CTA examination separately) and the experimental group (n=50) who underwent a one-stop-shop protocol (combined brain CT perfusion and head-and-neck CTA, the CTA triggering time determined by a low-dose test bolus injection). The examination time, contrast-agent dosage, radiation dose, postprocessing time, and image quality were compared between the two groups. RESULTS: Compared to the control group, the experimental group had a significantly lower total iodine contrast-agent dosage (80 vs. 100 ml, P<0.001) and shorter scan time (3.23 [3.13, 3.35] vs. 2.32 [2.17, 2.45] min, P<0.001). Additionally, the radiation dose exposure was lower in the experimental group than in the control group (5129.00 [5173, 5232] vs. 4681.35 [4555.12, 4822.95] mGy-cm, P<0.001). No statistically significant differences were observed between the two groups in terms of postprocessing time, head-and-neck CTA, and CTP imaging quality. CONCLUSION: The one-stop-shop protocol enables effective detection of lesions, providing clear visualization of the location and degree of stenosis in the head-and-neck vessels. It achieves this with lower costs in scan time, contrast-agent dosage, and radiation dose compared to the traditional protocol and is thus worth considering as the first examination for patients who suffer from acute ischemic stroke.

Double low-dose computed tomography (CT) angiography of craniocervical arteries using a test bolus of diluted contrast medium and a personalized contrast protocol.

AIM: To prospectively assess the value of a test bolus of diluted contrast medium (CM) combined with a personalized contrast protocol in craniocervical computed tomography angiography (cc-CTA) with low radiation and CM doses. MATERIALS AND METHODS: Eighty-six consecutive subjects were divided into two groups at random (43 in each one): group A: 100/Sn140 kVp, filtered back-projection reconstruction, iopromide (370 mgI/ml) 50 ml; group B: 80/Sn140 kVp, iterative reconstruction, iodixanol (270 mgI/ml). In group B, the test bolus contained 27 ml of diluted CM, a personalized protocol with low-concentration CM was used for angiography, and the test bolus injection duration in angiography remained the same. Artery values over 200 Hounsfield units were considered significant. RESULTS: Image quality for all cases was found to be diagnostic. No significant differences were found in the arterial densities of the ascending aorta or basilar artery between the groups. The values of the common carotid artery, internal carotid artery, and middle cerebral artery in group B were significantly lower. The effective dose and average iodine uptake were significantly lower in group B. CONCLUSION: With double-low-dose cc-CTA, test bolus scanning based on diluted CM combined with a personalized contrast protocol can yield diagnostic-quality images and significantly reduce the radiation and CM doses.

[Cytoplasmic light-chain immunofluorescence combined with FISH in bone marrow smears to detect cytogenetic abnormalities in multiple myeloma].

Objective: To analyze the sensitivity of cytoplasmic light-chain immunofluorescence with fluorescence in situ hybridization in bone marrow smears (new FISH) for detecting cytogenetic abnormalities in multiple myeloma (MM) . Methods: 42 MM patients admitted to the First Affiliated Hospital of Nanjing Medical University from April 2022 to October 2023 were enrolled. The patients with MM were detected by new FISH and CD138 immunomagnetic bead sorting technology combined with FISH (MACS-FISH) or cytoplasmic immunoglobulin FISH (cIg-FISH) to analyze cytogenetic detection results using combination probes which included 1q21/1p32, p53, IgH, IgH/FGFR3 [t (4;14) ], and IgH/MAF [t (14;16) ]. Results: In 23 patients with MM, the abnormality detection rates of cIg-FISH and new FISH were 95.7% and 100.0%, respectively (P>0.05). The detection rates of 1q21+, 1p32-, p53 deletion, and IgH abnormalities by cIg-FISH and new FISH were consistent, which were 52.2%, 8.7%, 17.4%, and 65.2%, respectively. The results of the two methods further performed with t (4;14) and t (14;16) in patients with IgH abnormalities were identical. The positive rate of t (4;14) was 26.7%, whereas t (14;16) was not detected. In 19 patients with MM, the abnormality detection rates of MACS-FISH and new FISH were 73.7% and 63.2%, respectively (P>0.05). The positivity rate of 1q21+, 1p32- and IgH abnormalities detected by MACS-FISH were slightly higher than those detected by new FISH; however, the differences were not statistically significant (all P values >0.05) . Conclusion: The new FISH method has a higher detection rate of cytogenetic abnormalities in patients with MM and has good consistency with MACS-FISH and cIg-FISH.

[Type of CEBPA mutations in acute myeloid leukemia and their effect on prognosis].

Objective: To demonstrate the type of CEBPA gene mutations among patients with acute myeloid leukemia (AML), clinical characteristics, and prognostic effect on patient outcomes. Methods: Demographic data, clinical features, laboratory characteristics, and data about treatment and follow-up of 57 patients with CEBPA mutated AML diagnosed at Peking Union Medical College Hospital between April 2016 and November 2022 were collected and analyzed. Results: In total, 57 patients with CEBPA mutation accounted for 16.1% of all the 353 patients with AML, among which 28 patients had CEBPA-bZIPinf and 29 had CEBPA-other. Compared with the CEBPA-other group, the CEBPA-bZIPinf group was younger (54 vs 64 years, P=0.010), de novo AML was more common (P=0.001), and the level of bone marrow blast was higher (68.0% vs 36.3%, P=0.001). Moreover, 24 patients from the CEBPA-bZIPinf group and 19 from the CEBPA-other group received chemotherapy. The one-course complete remission (CR) rate of the CEBPA-bZIPinf group was significantly higher than that of the CEBPA-other (87.5% vs 47.4%, P=0.010) and CEBPA-wt (87.5% vs 50.3%, P=0.002) groups. After a median follow-up of 11 months, the median OS of the CEBPA-bZIPinf group was significantly longer than that of the CEBPA-wt group (not reached vs 22.1 months, P=0.012) . Conclusion: CEBPA-bZIPinf mutated AML is a unique clinical entity, with a younger age of diagnosis, better response to chemotherapy, and better prognosis.

What are the 100 most cited fungal genera?

The global diversity of fungi has been estimated between 2 to 11 million species, of which only about 155 000 have been named. Most fungi are invisible to the unaided eye, but they represent a major component of biodiversity on our planet, and play essential ecological roles, supporting life as we know it. Although approximately 20 000 fungal genera are presently recognised, the ecology of most remains undetermined. Despite all this diversity, the mycological community actively researches some fungal genera more commonly than others. This poses an interesting question: why have some fungal genera impacted mycology and related fields more than others? To address this issue, we conducted a bibliometric analysis to identify the top 100 most cited fungal genera. A thorough database search of the Web of Science, Google Scholar, and PubMed was performed to establish which genera are most cited. The most cited 10 genera are Saccharomyces, Candida, Aspergillus, Fusarium, Penicillium, Trichoderma, Botrytis, Pichia, Cryptococcus and Alternaria. Case studies are presented for the 100 most cited genera with general background, notes on their ecology and economic significance and important research advances. This paper provides a historic overview of scientific research of these genera and the prospect for further research.
