Guidelines for the prevention and treatment of chronic hepatitis B (2022 edition) are updated and revised based on the research advances in chronic hepatitis B virus infection in China and globally and the previous editions of the guidelines. This article introduces the updates in natural history and the noninvasive diagnosis and treatment of fibrosis. In particular, the guidelines further expand the indications for patients with chronic hepatitis B virus infection, clearly defines the selection of the population benefiting from interferon therapy, and strictly limits the standard of oral nucleos(t)ide analogues. Meanwhile, the guidelines also recommend more active treatment of patients with low-level viremia and children in the immune-tolerant phase. The new edition of the guidelines will provide an important basis for expanding the screening for hepatitis B virus infection, improving diagnostic rate, optimizing treatment regimens, and standardizing clinical management in China.

Brucellosis is a zoonotic disease caused by Brucella. Its typical clinical manifestations include fever, chills, fatigue, bone and muscle pain, etc. Brucellosis can affect multiple organs and tissues, of which spine is the most common affected part, forming Brucella spondylitis. Due to the clinical manifestations and imaging characteristics of infected individuals being similar to other spinal diseases, it is easy to cause misdiagnosis, missed diagnosis, and mistreatment. This article reviews the latest research progress in clinical manifestations, imaging examination, diagnosis, differential diagnosis, and treatment of Brucella spondylitis both domestically and internationally, in order to provide reference for the diagnosis and treatment of Brucella spondylitis.

Objective:To analyze the diagnostic value of metabolic makers in cerebrospinal fluid in advanced lung adenocarcinoma patients with leptomeningeal metastases (LM) .Methods:A total of 46 cerebrospinal fluid samples (LM group) from lung adenocarcinoma patients with LM admitted to Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from December 2019 to December 2021 were collected, and 48 cerebrospinal fluid samples (control group) from patients with benign neurological diseases during the same period were collected. Metabolomics analysis of cerebrospinal fluid was carried out by high-performance liquid chromatography-mass spectrometry. Principle component analysis (PCA) and orthogonal to partial least squares discriminant analysis (OPLS-DA) were used for modeling. Multi-criteria assessment was used to identify the different metabolites between the two groups. Receiver operating characteristic (ROC) curve, pathway enrichment analysis and other methods were used to screen metabolites and pathways related to LM from lung adenocarcinoma.Results:There were no statistically significant differences in the proportions of age ( Z=-0.41, P=0.210) , gender ( χ2=1.19, P=0.275) , history of smoking ( χ2=2.86, P=0.091) , Karnofsky performance status score ( χ2=0.65, P=0.419) and increased intracranial pressure ( χ2=0.65, P=0.419) between the LM group and control group. The models of PCA (R2X was 0.608 and 0.583, Q2 was 0.462 and 0.513 in electrospray ion positive and negative modes, respectively) and OPLS-DA (R2Y was 0.967 and 0.889, Q2 was 0.959 and 0.852 in electrospray ion positive and negative modes, respectively) showed that the overall data quality was good. Meanwhile, the model interpretation rate and prediction rate were effective. The permutation tests duplicated for 200 times and showed no over-fitting of the established model. The metabolic profiles of the two groups were significantly different. A total of 30 endogenously differential metabolites were screened by using multi-criteria assessment. Six potential biomarkers with larger area under the curve (AUC) were identified through ROC curve analysis, including tyrosine (AUC=0.967, 95% CI: 0.906-1.000) , phenylalanine (AUC=0.992, 95% CI: 0.973-1.000) , pyruvate (AUC=0.976, 95% CI: 0.935-1.000) , tryptophan (AUC=0.935, 95% CI: 0.880-0.973) , glucose (AUC=0.932, 95% CI: 0.880-0.975) and adenosine monophosphate (AUC=0.993, 95% CI: 0.987-1.000) . The 30 selected differential metabolites were enriched and analyzed for metabolic pathways, and 20 relevant metabolic pathways were matched. Among them, the four metabolic pathways most likely to cause changes in metabolites were glycolysis and glucose metabolic synthesis, pyruvate metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis. Conclusion:Untargeted metabolomics analysis can effectively screen specific cerebrospinal fluid metabolites in lung adenocarcinoma patients with LM. Six potential metabolites such as tyrosine, phenylalanine, pyruvate, tryptophan, adenosine monophosphate, glucose and their metabolic pathways may be involved in the pathogenesis of LM from lung adenocarcinoma.

Objective:To investigate the biological characteristics of proliferation, apoptosis, migration and invasion of radiation-induced polyploid cervical cancer HeLa cells, and to analyze the potential facilitation of polyploid HeLa cells in cervical cancer recurrence after radiotherapy.Methods:HeLa cells were irradiated by 6 MV-X ray with 7 Gy and 14 Gy, the cells were cultured until the third day, and then they were recorded as 7 Gy group and 14 Gy group respectively. The unirradiated HeLa cells were recognized as the control group. The cell morphology was checked under optical microscope. Flow cytometry was used to determine cell ploidy. MTT assay was applied to detect cell proliferation. Flow cytometry by AnnexinⅤ-FITC/PI double labeling was used to detect apoptosis. The ability of migration and invasion was detected by Transwell assay. The expression levels of STAT3 signal pathway-related proteins were analyzed by Western blotting.Results:Compared with the control group, the volume of HeLa cells in 7 Gy group and 14 Gy group increased significantly. The percentages of polyploid HeLa cell subsets in the control group, 7 Gy group and 14 Gy group were (6.33±1.26) %, (21.13±0.50) % and (46.07±1.68) % respectively, with a statistically significant difference ( F=780.47, P<0.001) . The absorbance values in the control group, 7 Gy group and 14 Gy group of polyploidy HeLa cells were 0.21±0.01, 0.23±0.02, 0.16±0.01 at 24 h, 0.37±0.03, 0.38±0.06, 0.21±0.00 at 48 h, 0.66±0.02, 0.55±0.01, 0.28±0.01 at 72 h, and there were statistically significant differences ( F=31.62, P=0.001; F=20.10, P=0.002; F=708.52, P<0.001) . Further pairwise comparison showed that the proliferation abilities of polyploidy HeLa cells of the 14 Gy group at 24, 48 and 72 h were significantly lower than those of the control group and the 7 Gy group (all P<0.05) . The proportions of apoptotic cell subset in the control group, 7 Gy group and 14 Gy group were (3.67±1.16) %, (3.07±0.81) %, (3.83±0.91) %, the proportions of early apoptotic subset were (2.33±0.35) %, (2.13±0.61) %, (2.23±0.32) %, and the proportions of late apoptotic subset were (1.33±0.81) %, (0.93±0.31) %, (1.60±0.60) % respectively. There were no statistically significant differences ( F=0.52, P=0.620; F=0.15, P=0.864; F=0.92, P=0.450) . The migrated numbers of cells in the control group, 7 Gy group and 14 Gy group were 297.40±26.53, 121.33±15.16, 18.40±4.79, and the invaded numbers were 195.67±20.26, 63.60±6.91, 9.47±3.23 respectively, with statistically significant differences ( F=647.28, P<0.001; F=213.94, P<0.001) . Compared with the control group, the migration and invasion abilities of polyploid HeLa cells in the 7 Gy and the 14 Gy groups were significantly decreased, and the migration and invasion abilities of polyploid HeLa cells in the 14 Gy group were significantly lower than those in the 7 Gy group (all P<0.001) . The expression levels of P-STAT3 (Tyr 705) and Bcl-2 in radiation-induced polyploidy HeLa cells were higher than those in the control group, and the expression levels were further increased with the increase of radiation dose. Compared with the control group, the expression levels of Survivin and Mcl-1 in polyploid HeLa cells in the 14 Gy group were up-regulated (both P<0.05) . There was no significant difference in Bcl-xL expression among the three groups ( F=0.52, P=0.618) . Conclusion:The proliferation, migration and invasion abilities of polyploid HeLa cells are reduced by radiation, and the proportion of apoptotic subset is not significantly changed, but the activation of STAT3 signaling pathway is accompanied by up-regulation of downstream anti-apoptotic related proteins, which is favorable for the polyploid tumor cells to be the potential risk factor of recurrent cervical cancer after radiotherapy.

Objective At present, the novel coronavirus pneumonia (COVID-19) pandemic is still raging in certain regions around the globe, and the prevention and control of the pandemic should be strengthened. Under the challenges of respective social environment and allocation of medical resources, and support from the inertia and inherent productivity of the system on which the industry depends, extensive attempts are being delivered to push forward the work of organ donation and transplantation in each country. Under the guidance of national experts and committee members, Shanxi Provincial Human Organ Procurement and Allocation Service Center was established on August 28, 2018 approved by the former Shanxi Provincial Health and Family Planning Commission. It is the only independent non-profit medical institution in Shanxi Province. In this article, the system construction of citizen's organ donation and transplantation fitting national and provincial conditions was further explored according to the data analysis of organ donation and transplantation in the United States and Spain during the COVID-19 pandemic combined with the implementation of organ donation work in Shanxi Provincial Human Organ Procurement and Allocation Service Center.

Objective:To explore the expression of peptidyl prolyl cis-trans isomerase (Pin1) activity in peripheral blood of patients with rheumatoid arthritis (RA) and the value and correlation of T helper cell 17/regulatory cells (Th17/Treg) cells, and to analyze the effect and influence of all-transretinoic acid (ATRA) on it.Methods:① Comparing the difference of Pin1 expression and absolute counts of Th17 and Treg between RA patients before and after treatment and healthy control group, Kruskal-Wallis rank sum test was used for analysis. ② To analyze the correlation between the expression of Pin1 and its general data, activity indicators [such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score 28 joints (DAS28) scores], Th17, Treg and some cytokines in RA patients, and to use Pearson and Spearman correlation tests. ③ To analyze the difference of Pin1 expression and Th17/Treg in peripheral blood of RA patients treated with low-dose all-trans retinoic acid (10 mg twice a week) and traditional immunosuppressants such as hydroxychloroquine for 3 months respectively. Mann-Whitney U test was used for comparison between the two groups, and the difference was statistically significant with ( P<0.05). Results:① The activity of Pin1 in peripheral blood of the newly treated group of RA was [13.62(9.16, 19.42)] higher than that of the healthy control group [8.97(7.62, 11.45)]( Z=42.82 , P<0.05), and Th17 was [18.28(12.76, 24.08)] higher than that of the healthy control group [6.04(4.96, 4.96)]( Z=48.83 , P<0.05). Treg [11.06(5.31, 21.87). It was lower than that of healthy control group [40.41(24.33, 48.52)]( Z=42.21 , P<0.05). ② the activity of Pin1 in peripheral blood of RA patients was positively correlated with CRP, the number of involved joints, DAS28 score, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) ( r=0.396, P<0.05; r=0.683, P<0.05; r=0.466, P<0.05; r=0.315, P<0.05; r=0.416, P<0.05). ③ Compared with the newly treated RA group, the activity of Pin1 [6.94(5.96, 8.77), Z=42.82 , P<0.05] and Th17 7.38 decreased [7.38(3.85, 11.21), Z=48.83 , P<0.05], while Treg [40.41 (17.77, 33.47)] increased ( Z=42.21 , P<0.05). ④ Compared with the traditional medicine group, Treg [28.9(21.73, 37.36)] was higher in the retinoic acid group, and the difference was statistically significant ( Z=-2.683 , P<0.05). The activity of Pin1 was [6.23(5.58, 8.75)], but there was no statistical significance ( Z=-1.622 , P=0.104). Conclusion:Pin1 in peripheral blood of RA patients is over-expressed. Th17 is increased and Treg is decreased. ATRA combined with other traditional drugs can reduce Pin1 activity, promote Treg growth and improve disease activity of RApatients to a certain extent.

Objectives:To explore the GAA varient spectrum and the genotype-phenotype correlations in patients with glycogen storage disease type Ⅱ (Pompe disease, PD), as well as to estimate the disease incidence based on carrier rate of GAA varients in Guangzhou population.Methods:A total of 57 PD cases were retrospectively enrolled at Guangzhou Women and Children′s Medical Center from January 1, 2010 to May 31, 2020. All patients presented symptoms before the age of 18 years. Each diagnosis was further confirmed by GAA enzyme activity and GAA variants. The carrier rate of GAA varients was calculated based on variants detected by whole exon sequencing among 2 395 healthy children in Guangzhou.Results:Among the 57 PD patients (including male 26, female 31),twenty-eight patients with infantile onset PD (IOPD) presented with progressive general muscle weakness and cardiomyopathy. The mean ages of symptom onset and diagnosis were (2.5±1.4) and (5.0±3.0) months, respectively. Twenty-six cases died in the first year after birth.Twenty-three patients with late onset PD (LOPD) presented with progressive muscle weakness. Seven of them had respiratory failure at diagnosis. The mean ages of symptom onset and diagnosis were (12.0±5.0) and (17.0±7.5) years, respectively. Six children with atypical IOPD showed motor delay, muscle weakness and cardiomyopathy. Their diagnosis was confirmed at 2.5-7.0 years of age. Among the 57 patients, 47 different variants were identified in the GAA gene. Three variants: c.797C>T, c.1109G>A and c.1757C>T were novel. c.1935C>A (25/114, 21.9%) and c.2238G>C (15/114, 13.2%) were the most common variants, detected in 57.1% of IOPD and 65.2% (15/23) of LOPD patients, respectively. Among the 28 IOPD patients, 26 cases (92.9%) carried at least one missense variant which indicated positive cross-reactive immunologic material (CRIM). The carrier rate of pathogenic variants in GAA gene among healthy children was 24/2 395. The estimated incidence of PD in this population is about 1/40 000. The frequencies of pseudodeficiency variants c.1726G>A and c.2065G>A homozygotes were 26.3% (15/57) and 35.1% (20/57) in PD patients, which were significantly higher than those (1.7% (40/2 395) and 3.9% (94/2 395)) in healthy children (χ2=151.2, 121.9; both P<0.01). Conclusions:PD presents as a spectrum, some as atypical IOPD. The c.1935C>A and c.2238G>C are common variants, correlated with IOPD and LOPD respectively. The c.796C>T and c.1082C>T are usually found in atypical IOPD. The majority of IOPD patients is predicted to be CRIM positive. The estimated incidence of PD is about 1/40 000.

BACKGROUND: Leptomeningeal metastasis (LM) are a severe complication of non-small cell lung cancer (NSCLC), and normally accompanied by poor prognosis. For the patients with targetable mutations, epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are the preferred treatment, but the acquired TKI resistance is inextricable. The aim of this study is to analyze the different gene mutation spectrum and mutation frequency of the cerebrospinal fluid (CSF) and plasma in NSCLC patients with LM, and screen out the drug-resistant mutations so as to guide the choice of treatment accurately. METHODS: The paired CSF and plasma samples were collected from the NSCLC-LM patients with acquired TKI resistance. Next generation sequencing (NGS) was used to detect the gene variations of circulating tumor DNA (ctDNA). RESULTS: A total of 18 NSCLC patients with LM were collected. Of the basic mutations, 11 cases (61.11%) were EGFR, 6 cases (33.33%) were anaplastic lymphoma kinase (ALK), and 1 case (5.56%) was ROS proto-oncogene 1, receptor tyrosine kinase (ROS1). Tumor protein p53 gene (TP53) and mesenchymal-epithelial transition factor (MET) were the two most frequently accompanying mutated genes in CSF ctDNA. The detected mutation rate of CSF samples was higher than that of plasma samples (100.00% vs 66.67%, P=0.006), and the maximum allelic fractions were all higher in CSF than in plasma (P<0.001). Abundant single-nucleotide variations (SNV) and copy number variants (CNV) were detected in CSF, the amount of both of which were more than in blood. In addition, the CSF and plasma samples of patients treated with several TKIs had more SNV mutations than patients who received only a single TKI treatment. CONCLUSIONS For the patients of NSCLC, ctDNA in CSF could reveal genomic alterations of LM more exactly and overally than it in plasma, thus could be an optimal source of liquid biopsy for guiding therapy, monitoring therapeutic effect, and predicting prognosis.
