The classical prescription Yangweitang, derived from Zhengzhi Zhunsheng, is specialized in treating syndromes of chill and fever due to exogenous pathogens, inner-cooling, and malaria, and it has been included in the Catalogue of Ancient Classical Formulas (the First Batch) published by the National Administration of Traditional Chinese Medicine (TCM) in 2018. Through bibliographical research, the relevant ancient books and modern documents were systematically sorted out, and it was found that there were many prescriptions related to the Yangweitang from Zhengzhi Zhunsheng. They were interwoven with Yangweitang from Zhengzhi Zhunsheng and widely used in clinical practice. In order to clarify their history and evolution, this paper combed the historical origin of Yangweitang and its related prescriptions and conducted textual analysis on key information such as semantic composition, herb origin, processing method, and efficacy. A total of 896 pieces of data on Yangweitang from Zhengzhi Zhunsheng were collected. 26 pieces of effective data were included after the screening, involving 17 ancient TCM books. Then, a total of 28 pieces of data on prescriptions related to the Yangweitang from Zhengzhi Zhunsheng were included, involving 23 ancient TCM books for reference. The textual analysis showed that Yangweitang originated from the Renshen Yangweitang recorded in Taiping Huimin Heji Jufang in the Song dynasty. Based on the original formula, medical experts from later generations have modified it into many different versions. A comparative analysis showed that Yangweitang from different generations had similar compositions, and the herb origin and processing method were basically clear. The recommended prescriptions are as follows: 37.3 g of Pinelliae Rhizoma Praeparatum Cum Alumine, Magnoliae Officinalis Cortex(fried with ginger juice), and frying with rice water Atractlodis Rhizoma, 27.98 g of Citri Exocarpium Rubrum, 18.65 g of Pogostemon cablin leaf, Tsaoko Fructus, Poria, and Ginseng Radix et Rhizoma, and 9.33 g of Glycyrrhizae Radix et Rhizoma. They could be ground into a coarse powder, with 14.92 g for every dose, and they could be orally taken after being decocted with 450 mL of water, 7 g of fresh ginger, and 2 g of Mume Fructus to 270 mL in warm conditions. Yangweitang from Zhengzhi Zhunsheng has the effect of warming the middle and releasing the external, and it can treat many syndromes including spleen and stomach disharmony caused by chill and fever due to exogenous pathogens and inner-cooling, as well as all kinds of malaria. Modern clinical applications mainly focus on chronic atrophic gastritis and other digestive system diseases.

Objective:To investigate the survival rates of patients with liver cancer in Shanghai from 2002 to 2013. Methods:Data on new cases and deaths of liver cancer patients withfollow-up information from 2002 to 2013 were obtained from the Population-Based Cancer Registry and Vital Statistics System of the Shanghai Municipal Center for Disease Control and Prevention.Incidence and survival rates were stratified by year of diagnosis,gender,district,age-group and stage at diagnosis for analysis.Statistical indicators,such as case numbers,proportions,median age and mean age were calculated.The 1-to 5-year observed survival rates were calculated based on the life table method.The probabilities of surviving from 0 to 99 years old were estimated with the Elandt-Johnson model,and then cumulative expected survival rates were calculated using the Ederer Ⅱ method.Finally,the 1-to 5-year relative survival rates were calculated. Results:A total of 49 455 new cases of liver cancer were diagnosed from 2002 to 2013 in Shanghai,including 35 115 males and 14 340 females.The ratio of males to females was 2.45:1.The proportions of stage Ⅰ,stage Ⅳ and stage unknown were 3.32%,13.93%and 69.13%,respectively.The median survival time of patients with liver cancer diagnosed from 2002 to 2013 was 0.77 years,the 5-year observed survival rate was 13.23%,and the 5-year relative survival rate was 14.47%.According to the 5-year observed survival rate and 5-year relative survival rate of the cases,both survival indicators were higher in urban areas than in suburban areas,higher in males than in females,higher in cases under 45 years of age than in those over 75 years of age,higher in cases diagnosed from 2011 to 2013 than those diagnosed from 2002 to 2004.Additionally,the survival rate of cases decreased with increasing stage at diagnosis. Conclusion:With the continuous improvement of the diagnosis and treatment of liver cancer in Shanghai,the survival rate of patients with liver cancer has shown a significant upward trend over time.However,compared with various malignant tumors such as gastric cancer and breast cancer,the improvement effect of liver cancer survival rate is still not significant.Additionally,a high proportion of cases with unknown clinical stage at the time of diagnosis and a low survival rate of stage Ⅳ cases were observed.This study provides a basis for the prevention and research of liver cancer.
7.New progress on clinical characteristics and related mechanisms of chronic ocular graft-versus-host disease
Organ Transplantation 2022;13(2):187-
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) could effectively treat multiple hematological diseases. At present, with persistent improvement of transplantation techniques and rapid development of economy, more and more patients with hematological diseases are able to survive for a long time due to allo-HSCT treatment. Chronic ocular graft-versus-host disease (coGVHD) is the most common ocular complication after allo-HSCT, which is primarily manifested with refractory dry eye. In severe cases, it may cause imbalance of ocular surface homeostasis and limbal stem cell insufficiency, further leading to a series of complications that threaten the visual function and eye health, such as corneal perforation and symblepharon,

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with unknown etiology and limited therapeutic options. Activation of fibroblasts is a prominent feature of pulmonary fibrosis. Here we report that lncRNA DACH1 (dachshund homolog 1) is downregulated in the lungs of IPF patients and in an experimental mouse model of lung fibrosis. LncDACH1 knockout mice develop spontaneous pulmonary fibrosis, whereas overexpression of LncDACH1 attenuated TGF-β1-induced aberrant activation, collagen deposition and differentiation of mouse lung fibroblasts. Similarly, forced expression of LncDACH1 not only prevented bleomycin (BLM)-induced lung fibrosis, but also reversed established lung fibrosis in a BLM model. Mechanistically, LncDACH1 binding to the serine/arginine-rich splicing factor 1 (SRSF1) protein decreases its activity and inhibits the accumulation of Ctnnb1. Enhanced expression of SRSF1 blocked the anti-fibrotic effect of LncDACH1 in lung fibroblasts. Furthermore, loss of LncDACH1 promoted proliferation, differentiation, and extracellular matrix (ECM) deposition in mouse lung fibroblasts, whereas such effects were abolished by silencing of Ctnnb1. In addition, a conserved fragment of LncDACH1 alleviated hyperproliferation, ECM deposition and differentiation of MRC-5 cells driven by TGF-β1. Collectively, LncDACH1 inhibits lung fibrosis by interacting with SRSF1 to suppress CTNNB1 accumulation, suggesting that LncDACH1 might be a potential therapeutic target for pulmonary fibrosis.

Objective:To analyze the functional connectivity (FC) characteristics of sensory motor network (SMN) in patients with bipolar disorder type Ⅰ (BD-Ⅰ) by independent component analysis (ICA), and explore the correlation between abnormal SMN and clinical symptoms.Methods:Eighteen patients with BD-Ⅰ (BD-Ⅰ group) and 20 matched normal controls (HC group) were included.Both groups received resting state fMRI (rs-fMRI) scanning.Based on ICA-fMRI data, one-sample t-test and two-sample t-test were used to analyze the components of SMN and to explore abnormal brain regions between the two groups.Functional network analysis (FNC) was also used to explore the functional connectivity between SMN and other brain networks.Pearson correlation analysis were conducted by SPSS 17.0 to measure the potential associations between intra-and inter-network functional connectivity and age, education, score of Bech-Rafaelsen mania rating scale (BRMS), score of positive and negative syndrome scale (PANSS) and other indicators. Results:In BD-Ⅰ group, the functional connection in the right paracentral lobule (MIN: x=8, y=-32, z=68, t=4.86, P<0.001) and the right postcentral gyrus (MIN: x=41, y=-26, z=53, t=3.33, P<0.001) in SMN were higher than those in HC group.Compared with HC group, the connectivity value in patients with BD-Ⅰ increased between SMN-DAN (0.247±0.073, -0.078±0.080, t=-2.974, P<0.01, FDR adjusted), while the connectivity value decreased between SMN-DMN(-0.037±0.054, 0.272±0.067, t=3.520, P<0.01, FDR adjusted) and between SMN-rFPN(-0.034±0.055, 0.231±0.070, t=2.939, P<0.01, FDR adjusted). Conclusion:The sensorimotor network of patients with BD-Ⅰ has abnormal functional connections within and between networks, and FC values in some networks are positively correlated with manic symptoms, which may be part of the neural mechanisms of patients with BD-Ⅰ.

The importance of structural variants(SVs)for human phenotypes and diseases is now recognized.Although a variety of SV detection platforms and strategies that vary in sensitivity and specificity have been developed,few benchmarking procedures are available to confidently assess their performances in biological and clinical research.To facilitate the validation and application of these SV detection approaches,we established an Asian reference material by characterizing the genome of an Epstein-Barr virus(EBV)-immortalized B lymphocyte line along with identified benchmark regions and high-confidence SV calls.We established a high-confidence SV callset with 8938 SVs by integrating four alignment-based SV callers,including 109x Pacific Biosciences(PacBio)continuous long reads(CLRs),22 x PacBio circular consensus sequencing(CCS)reads,104x Oxford Nanopore Technologies(ONT)long reads,and 114×Bionano optical mapping plat-form,and one de novo assembly-based SV caller using CCS reads.A total of 544 randomly selected SVs were validated by PCR amplification and Sanger sequencing,demonstrating the robustness of our SV calls.Combining trio-binning-based haplotype assemblies,we established an SV benchmark for identifying false negatives and false positives by constructing the continuous high-confidence regions(CHCRs),which covered 1.46 gigabase pairs(Gb)and 6882 SVs supported by at least one diploid haplotype assembly.Establishing high-confidence SV calls for a benchmark sample that has been characterized by multiple technologies provides a valuable resource for investigating SVs in human biology,disease,and clinical research.
