Wuhutang is the 51st Chinese medicine prescription of Han ethnic group on in the catalogue of ancient classical prescriptions (the second batch) ,which originated from Renzhai' Straight Diections Prescriptions (《仁斋直指方》) by YANG Shiying in the Song dynasty,it is composed of 5 medicines, including Ephedrae Herba,Armeniacae Semen Amarum, Glycyrrhizae Radix et Rhizoma, tea and Gypsum Fibrosum. It treats shortness of breath and phlegm. Following the principle of textual research on the key information of ancient classical famous prescriptions, the author collected and recorded the ancient books of traditional Chinese medicine of Wuhutang with the method of Bibliometrics, and screened out 53 valid data, involving 41 ancient books. Based on the historical evolution, drug composition, main treatment of disease and syndrome, drug dosage, method of preparation and usage, drug origin and processing, the author conducted a dig and a systematic study of Wuhutang. The results show that:in the later generations, besides inheriting the original prescription, the composition of medicine was added or subtracted, and the frequency of addition of Mori Cortex was the most;in the treatment of disease and syndrome, most of them inherited the original prescription mainly treating asthma syndrome, also see in the treatment of asthma, cough and other lung disease, in the drug dosage and method of use , it is suggested to inherit the original prescription, the dosage of each medicine is: Ephedrae Herba 2.89 g, Armeniacae Semen Amarum 4.13 g, Glycyrrhizae Radix et Rhizoma 1.65 g, tea 3.30 g, Gypsum Fibrosum 6.20 g, decoction, take warm clothes before eating;on the source of medcine,ephedra is made from the dried herbaceous stems of Ephedra sinica (Ephedraceae),bitter almond is made from the dried and mature seeds of Prunus armeniaca (Rosaceae),Licorice is made from the dried roots and rhizomes of Glycyrrhiza uralensis(Legumes), tea is made from the buds leaves of Camellia sinensis(Camellia),plaster is made from Gypsum Fibrosum of sulfate mineral gypsum family. At the same time, we collected and sorted the modern clinical application literature of Wuhutang, and obtained 73 effective literatures, all of which are for the treatment of respiratory system diseases, especially for children's pneumonia and asthma, and mostly belong to"phlegm-heat obstructing the lung syndrome". Through the analysis and study of ancient books and modern applied literature, the historical evolution and prescription evolution of Wuhutang are clarified, and its key information is determined, in order to provide more accurate reference for the research and development of the classic Wuhutang and the rational addition and subtraction of the application.

Objective:To observe the clinical efficacy of body acupuncture combined with FANG's scalp acupuncture in treating limb dysfunction in the remission stage of stroke and explore the mechanism. Methods:Sixty patients in the remission stage of stroke with limb dysfunction were divided into a control group and a treatment group using the random number table method,with 30 cases in each group.The control group was treated with ordinary acupuncture based on the conventional rehabilitation treatment,and the treatment group was additionally offered FANG's scalp acupuncture.The interventions were conducted once daily with 10 sessions as 1 course.The Fugl-Meyer assessment(FMA)and Barthel index(BI)scores and serum malondialdehyde(MDA)and superoxide dismutase(SOD)levels were compared after 2 treatment courses,and the clinical efficacy was evaluated. Results:After treatment,the FMA and BI scores increased in both groups(P<0.05)and were higher in the treatment group than in the control group(P<0.05).Both groups showed a decreased MDA level and an increased SOD level after the intervention,all showing statistical significance(P<0.05);there were significant differences between the two groups(P<0.05). Conclusion:Based on the conventional rehabilitation treatment,ordinary acupuncture used alone or in combination with FANG's scalp acupuncture can lower the oxidative stress level and improve limb function in treating limb dysfunction in the remission stage of stroke;body acupuncture plus FANG's scalp acupuncture can produce better results.

Objective To analyze the characteristics of imported malaria epidemic from overseas in Wuhan, to explore the management mechanism of on-site cases, and to accumulate experience for the treatment of imported malaria in large cities after malaria elimination. Methods The epidemiological data on imported malaria from abroad during the period of malaria elimination (2010-2019) in Wuhan were collected. The gender, age and severe illness-related factors of the cases were analyzed. Based on the characteristics of the epidemic and the current situation of prevention and control, the content and experience of the “Municipal-District 24-7” case mechanism were discussed. Results The medical resources in Wuhan were the best in the central region, resulting in a large number of imported malaria cases, with a total of 474 cases reported from 2010 to 2019 (40.79% of the total number of cases in Hubei Province), including 359 cases of falciparum malaria, 36 severe cases and one death (the death rate was 0.28%). The patients were mainly young and middle-aged men aged 20 to 49 years old (97.26%). There were many referral cases (40.30%), and there was no seasonal clustering of cases reported. The undiagnosed proportion at the first visit was 44.85%, and the time of attack-diagnosis was 4 days or more in 61.00% of cases. The occurrence of severe cases was related to unconfirmed diagnosis at the first visit (χ2=35.46, P<0.001) and attack-diagnosis time (Z=-6.49, P<0.001). Conclusion Imported malaria occurs frequently in Wuhan, mainly falciparum malaria. However, “Municipal-District 24-7” case mechanism has effectively curbed the occurrence of severe and death cases and provided valuable experience for case management in similar cities in China.

Additional sex combs-like 1 (ASXL1) interacts with BRCA1-associated protein 1 (BAP1) deubiquitinase to oppose the polycomb repressive complex 1 (PRC1)-mediated histone H2A ubiquitylation. Germline BAP1 mutations are found in a spectrum of human malignancies, while ASXL1 mutations recurrently occur in myeloid neoplasm and are associated with poor prognosis. Nearly all ASXL1 mutations are heterozygous frameshift or nonsense mutations in the middle or to a less extent the C-terminal region, resulting in the production of C-terminally truncated mutant ASXL1 proteins. How ASXL1 regulates specific target genes and how the C-terminal truncation of ASXL1 promotes leukemogenesis are unclear. Here, we report that ASXL1 interacts with forkhead transcription factors FOXK1 and FOXK2 to regulate a subset of FOXK1/K2 target genes. We show that the C-terminally truncated mutant ASXL1 proteins are expressed at much higher levels than the wild-type protein in ASXL1 heterozygous leukemia cells, and lose the ability to interact with FOXK1/K2. Specific deletion of the mutant allele eliminates the expression of C-terminally truncated ASXL1 and increases the association of wild-type ASXL1 with BAP1, thereby restoring the expression of BAP1-ASXL1-FOXK1/K2 target genes, particularly those involved in glucose metabolism, oxygen sensing, and JAK-STAT3 signaling pathways. In addition to FOXK1/K2, we also identify other DNA-binding transcription regulators including transcription factors (TFs) which interact with wild-type ASXL1, but not C-terminally truncated mutant. Our results suggest that ASXL1 mutations result in neomorphic alleles that contribute to leukemogenesis at least in part through dominantly inhibiting the wild-type ASXL1 from interacting with BAP1 and thereby impairing the function of ASXL1-BAP1-TF in regulating target genes and leukemia cell growth.
