The number of women entering pregnancy with chronic liver disease is rising， and gestational liver disorders affect 3% of the pregnant population. Both can be associated with significant maternal and fetal morbidity and mortality. An international panel of experts with extensive experience in managing liver disease during pregnancy from various continents contributed to the formulation of these guidelines. This edition of the International Federation of Gynecology and Obstetrics guidelines on liver disease and pregnancy systematically addresses the most common diseases of gestational liver disorders and pregnancy comorbid with acute and chronic liver diseases and summarizes evidence-based clinical guidance and management recommendations， in order to enhance the clinical management of this patient population.

Objective:To analyze the morphologic changes and the extent of severity in end-stage heart disease; and to explore the correlation with their clinical features.Methods:Twelve cases of recipients who underwent pediatric cardiac allograft transplantation were collected from May 2022 to November 2023 at the Seventh Medical Center of People′s Liberation Army of China General Hospital. Gross pathologic examinations were performed and morphological changes were observed under a light microscope after HE, Masson′s trichrome, and reticulin staining. Semi-quantitative analysis of morphologic changes was performed. One case received DMD genetic testing, one received mtDNA variation testing for mitochondriopathy, and 1 received metagenomics next-generation sequencing. Clinical data and related literature were reviewed for comprehensive analysis.Results:There were 12 recipient hearts including 11 dilated cardiomyopathy (DCM) and 1 fulminant myocarditis (FM). The median age of DCM was 12 years (range, 3 to 15 years). DCM showed cardiomyocyte hypertrophy, cardiomyocyte disarray, nuclear morphological changes, interstitial fibrosis and fatty infiltration. One DCM was confirmed as Becker muscular dystrophy by DMD genetic testing. No pathogenic mutations were found in 1 patient that received mtDNA variation testing. H. influenzae was detected in the case of FM. FM showed diffuse and full-thickness inflammatory cell infiltration by large numbers of lymphocytes and plasma cells, scattered eosinophils, and few neutrophils.Conclusions:Cardiac transplantation is an excellent treatment for end-stage heart disease. The morphological features of DCM include cardiomyocyte hypertrophy, nuclear morphological changes, interstitial fibrosis and fatty infiltration. The severity of the lesion is influenced by multiple factors. FM predominantly presents diffuse infiltration of lymphocytes and plasma cells.

Objective:To investigate the differences in virological and immunological indicators of HIV-1 infected individuals with different degrees of immunosuppression, analyze the correlation between the sample/cutoff ratio (S/CO), viral load (VL), Western blot (WB) band type and immune status of HIV-1 infected individuals.Methods:A total of 639 HIV-1 antibodies positive and treatment-naive samples from Henan, Beijing and Yunnan during the period of 2017-2019 were divided into three groups: no immunosuppression (CD4≥500 cells/μl), mild immunosuppressive (350cells/μl≤CD4<500cells/μl), moderate immunosuppression (200 cells/μl≤CD4<350 cells/μl), severe immunosuppression (CD4<200 cells/μl). Chi-square test was used to compare S/CO, WB band type among different immunosuppression groups, analyze the relationship between various indicators and immune status.Results:In each immunosuppressive group, S/CO>20 had the highest occurrence rate (>37%), and showed a decreasing trend with the enhancement of immunity ( P<0.05), the occurrence rate of 119%), the occurrence rate of 078%), while the occurrence rates of p55 (<40%) and p39 (<3%) were the lowest, the differences of the occurrence rates of gp41 and p51 among different immunosuppression groups were statistically significant ( P<0.05). The area under the curve determined by S/CO value combined with viral load for no, mild, moderate and severe immunosuppression groups were respectively 0.651 (95% CI: 0.600-0.702; P<0.05), 0.587 (95% CI: 0.540-0.635; P<0.05), 0.605 (95% CI: 0.560~0.650; P<0.05), 0.647 (95% CI: 0.586-0.708; P<0.05). Conclusions:The S/CO value viral load was the best for the determination of non-immunosuppressive status; The absence of gp41 and p51, S/CO>20 suggest that the patient may be in non or severe immunosuppressed state, respectively.
