Objective:The aim of the study is to investigate correlation between HVPG and other clinical parameters and risk factors of clinically significant portal hypertension (CSPH) in patients with compensated cirrhosis based on hepatic vein pressure gradient (HVPG).Methods:82 patients with compensated cirrhosis were prospectively recruited in the Department of Infectious Diseases of Shulan Hospital from April 2021 to August 2021. Collected the basic data of each patients, laboratory examination results, liver stiffness, gastroscopy, and HVPG. Pearson correlation analysis, univariate logistic regression analysis and multivariate regression analysis are used to find the risk factors of patients with CSPH.Results:The median HVPG of 82 patients were 9.0(8.3)mmHg. There are 31 cases (27.8%) have developed CSPH, and the correlation analysis shown that CSPH was positively correlated with total bilirubin, INR and liver stiffness, but negatively correlated with albumin, hemoglobin and platelet count. According to univariate logistic regression analysis, the factors which can affecting CSPH include male, diabetes, esophageal gastric varices, albumin, hemoglobin, INR, blood sodium, white blood cells, platelet count, liver stiffness and CTP, FIB-4, ALBI, etc. After adjusted by multivariate analysis, only platelet counts, liver stiffness, esophageal gastric varices were independent risk factors for CSPH in patients with compensated cirrhosis.Conclusion:HVPG is the gold criteria for assessment of portal hypertension. The platelet count, liver stiffness, esophageal gastric varices are independently associated with the development of CSPH in patients with compensated cirrhosis, which can help assess PH and give early diagnosis and treatment to improve their prognosis.

Objective:To analyze the genomic characteristics of H7N9 avian influenza virus in external environment in Huainan city in 2016.Methods:Samples such as poultry feces, cages, table or cutting board, depilator, poultry drinking water and sewage in live poultry markets were collected. PCR positive samples of H7N9 and H9 subtypes ( Ct value ≤30) were selected. RNA was extracted from chicken embryos after isolation and culture. Results:Fourty-six H7N9 subtypes, 71 H9 subtypes and 38 H5 subtypes were detected from 150 environmental samples in Huainan city in 2016. Two H7N9 subtypes were successfully isolated. Genetic evolution analysis showed that the hemagglutinin (HA) and neuraminidase (NA) genes of the two H7N9 strains in Huainan city were in the branch of the Yangtze river delta, while the other six endogenous genes had no obvious regional distribution and clustering. G186V and Q226L of HA receptor site amino acids mutated. NA stem area missed "QISNT" sequence, while R294K and E119V resistance sites showed no variation. PA gene I550L, PB1 gene I368V and PB2 gene I504V were mutated in the polymerase. The N205S and P42S of the NS-1 gene changed to enhance the pathogenicity. M1 gene N30D, T215A, M2 gene S31N drug resistance gene loci mutated.Conclusions:The avian influenza virus was highly prevalent in the live poultry market in Huainan city in 2016. Meanwhile, the ability of the H7N9 subtypes to infect humans has increased. M2 ion channel inhibitor (related to the M2 gene) developed resistance, while NA inhibitors (related to the NA gene) remain susceptible and effective drugs.

Objective:To analyze the genomic characteristics of H9N2 subtype avian influenza virus in external environmental specimens collected in Huainan city from February to April, 2016.Methods:Specimens positive for H9N2 nucleic acid (Ct value≤30) were screened by fluorescent PCR and cultivated in chicken embryos to extract RNA. Eight gene segments were amplified and analyzed with whole genome sequencing. The molecular characteristics of each gene segment of Huainan strains were analyzed. A phylogenetic tree was constructed based on the sequences.Results:The hemagglutinin (HA) and neuramidinase (NA) genes of two Huainan H9N2 avian influenza strains and the human-derived strain A/Anhui-Lujiang/39/2018/H9N2 shared the homology of 98.2%-98.3% and 97.2%-94.9% in nucleotide and 98.9%-98.8% and 99.2%-98.6% in amino acid. The other six endogenous genes were highly homologous to those of the A/Anhui/1/2013/H7N9 and A/Anhui/33163/2016/H5N6 strains. The phylogenetic tree showed that two H9N2 subtype avian influenza strains isolated in Huainan city in 2016 belonged to G57 genotype, and the endogenous genes of two Huainan H7N9 isolates and human-derived A/Anhui/1/2013/ H7N9 and A/Anhui/33163/2016/H5N6 strains were G57-like genotype. Amino acid mutations in the HA protein receptor binding domain including S132D, K138T, T189D, V/A190T and Q226L were detected. The " TEI" sequence was deleted from the NA stem region. Amino acid mutations associated with drug resistance including H274Y, R292K and N294S were not detected in the isolates, but they carried the mutations of I550L in PA gene, I368V in PB1 gene, I504V in PB2 gene, P42S in NS1 gene, N30D and T215A in M1 gene and S31N in M2 gene.Conclusions:The two H9N2 viruses isolated in the live poultry market in Huainan city were highly homologous to the A/Anhui-Lujiang/39/2018/H9N2 strain isolated from humans. The three strains were within the same evolutionary branch and belonged to G57 genotype. The endogenous genes of the two H9N2 viruses could recombine with H7N9 and H5N6 subtype avian influenza viruses that caused human infection. Amino acid mutations in the HA protein receptor binding domain, deleted sequences in the NA stem region and increased polymerase activity strengthened the ability of viruses to infect humans and were related to the drug resistance to M2 ion channel inhibitors (adamantane). The two Huainan H9N2 viruses remained sensitive to NA inhibitors (oseltamivir phosphate).

Objective:To investigate the prevalence and severity of anemia and its effect on one-year survival in HBV related decompensated cirrhosis patients (HBV-DC).Methods:647 consecutive HBV-DC patients were prospectively enrolled from January 2016 to December 2018 in Hwamei Hospital, University of Chinese Academy of Sciences. Anemia and the baseline characterics of patients were evaluated. Cox regression analysis was used to evaluate the impact on one-year survival.Results:Of 647 HBV-DC patients, 406 were complicated with anemia, accounting for 62.8% of the total population, including 254 patients with mild anemia (39.3%), 122 with moderate anemia (18.9%), and 30 with severe anemia (4.6%). 133 died in 1 year, with a mortality rate of 20.6%. On cox regression analysis, age ( HR, 1.033; 95% CI, 1.017-1.049), hemoglobin ( HR, 0.992; 95% CI, 0.985-0.999), WBC ( HR, 1.069; CI, 1.028-1.111), MELD score ( HR, 1.095; 95% CI, 1.070-1.120) were independent associated with 1-year mortality. The 1-year survival KM curve of anemia and its severity was significantly different ( P<0.001). Conclusions:The incidence of anemia in HBV-DC patients is as high as 62.8%. Anemia and its severity are important factors affecting the one-year prognosis of HBV-DC patients, which provide new ideas for clinical evaluation and prognosis assessment.

The lacquer figure with meridian-points marked of the western Han dynasty, unearthed in Tianhui town, Jinniu district, Chengdu in 2012, has been the earliest and the most complete human figure of meridian-acupoints in China so far. There were over ten courses of meridians, and over 100 visible acupoints as well as multiple intaglio inscriptions. All of them are valuable in academic study. The writers introduced the lacquer figure un- earthed in Laoguanshan in terms of the briefs and characteristics of meridian and acupoint distributions, which give the references to the future studies.
