RESUMEN
Objective To evaluate the effect of the current immunization strategy for hepatitis B virus (Hepatitis B) in blocking mother-to-infant transmission in Hubei Province, and to explore the mechanism and possible influencing factors of failure of mother-to-infant blockade. Methods A multi-stage random sampling method was used to select 2 counties or districts in Hubei Province. Through maternity hospital health handbook, neonatal health record or hospital medical record system, hepatitis B virus (HBV) surface antigen (HBsAg)-positive pregnant women in 2012-2018 years were included to retrospectively investigate their delivery status and the HBV infection status of their children. Results Among the 302 newborns, 32 were positive for HBsAg, and the success rate of blockade of mother-to-infant transmission of hepatitis B was 89.45%. Further analysis showed that 68.21% (206 / 302) of newborns were delivered in township hospitals, 66.23% (200 / 302) were delivered by caesarean section and 41.72% (126 / 302) were breastfed, while 16.89% (51/302) were positive for hepatitis B virus e antigen (HBeAg), and 41.06% (124/302) were positive for anti-HBe. The vaccination rate of hepatitis B immunoglobulin (HBIG) during pregnancy was 3.31% (10/302), and the newborn HBIG vaccination rate was 94.37% (285/302). There were 84.11% (254/302) of pregnant women taking protective measures in daily life. Logistic regression analysis showed that township hospitals (OR=2.82, P<0.05), HBeAg positivity during pregnancy (OR=8.68, P<0.05), and HBIG vaccination during pregnancy (OR=12.62 , P<0.05) were risk factors for failure of mother-to-infant blockade, while anti-HBe positivity during pregnancy (OR=0.22, P<0.05), vaccination of newborns with HBIG (OR=0.20, P<0.05), and protective measures taken in daily life (OR=0.28, P<0.05) were protective factors for mother-to-infant interruption. Conclusion Deliveries in township hospitals and HBeAg-positivity during pregnancy are more likely to fail in blocking of mother-to-infant transmission of hepatitis B. HBIG vaccination during pregnancy does not reduce the risk of blockade failure. Neonatal HBIG vaccination, anti-HBe positivity during pregnancy, and protective measures in daily life can reduce the risk of blockade failure of mother-to-infant transmission of hepatitis B.
RESUMEN
Development of thoracolumbar vertebra (TLV) and rib primordium (RP) is a common evolutionary feature across vertebrates, although whole-organism analysis of the expression dynamics of TLV- and RP-related genes has been lacking. Here, we investigated the single-cell transcriptome landscape of thoracic vertebra (TV), lumbar vertebra (LV), and RP cells from a pig embryo at 27 days post-fertilization (dpf) and identified six cell types with distinct gene expression signatures. In-depth dissection of the gene expression dynamics and RNA velocity revealed a coupled process of osteogenesis and angiogenesis during TLV and RP development. Further analysis of cell type-specific and strand-specific expression uncovered the extremely high level of HOXA10 3'-UTR sequence specific to osteoblasts of LV cells, which may function as anti-HOXA10-antisense by counteracting the HOXA10-antisense effect to determine TLV transition. Thus, this work provides a valuable resource for understanding embryonic osteogenesis and angiogenesis underlying vertebrate TLV and RP development at the cell type-specific resolution, which serves as a comprehensive view on the transcriptional profile of animal embryo development.
RESUMEN
Objective To evaluate the changes in anterior chamber structure of pelvic floor before and after total hysterectomy with transperineal ultrasonography.Methods Forty-five patients who would receive total hysterectomy were enrolled.The structures of the anterior pelvic floor were observed with transperineal ultrasonography 1 day pre-operation and 1,3 and 6 months after operation.The parameters at rest and max Valsalva were recorded and calculated,including the bladder neck-symphyseal distance (BSD),bladder neck descent (BND),urethral rotation angle (UR) and posterior urethrovesical angle (PUA).The changes of the parameters at different time were analyzed statistically.Results BSD at max Valsalva,BND,UR and PUA at max Valsalva at different time were significantly different (all P<0.05).Compared with those preoperative,BSD at max Valsalva decreased (H=2.627,P=0.009) and BND increased (q=-3.095,P=0.002) 3 months after operation,BSD at max Valsalva decreased (H=4.379,P<0.001),BND (q=-4.379,P< 0.001),UR (H=-2.861,P=0.004) and PUA at max Valsalva (q=-2.686,P=0.007) increased 6 months after operation.The remaining parameters were not significantly different between every two time points (all P > 0.05).Conclusion The changes of BSD,BND at max Valsalva,UR and PUA at max Valsalva occur at the initial period after the total hysterectomy.The total hysterectomy can damage the pelvic floor and early pelvic floor rehabilitation need to he provided.

Objective To evaluate the effect of hypotension factor on endotracheal tube cuff-in-duced damage to tracheal mucous membrane of rabbits. Methods Eighty healthy rabbits of both sexes, aged 3.0-3.5 months, weighing 2.5-3.5 kg, were divided into 16 groups(n=5 each)according to the cuff pressure and mean arterial pressure(MAP): different cuff pressures when MAP did not decrease groups(C1M1group, C2M1group, C3M1group, C4M1group), different cuff pressures when MAP de-creased by 20% of the baseline value groups(C1M2group, C2M2group, C3M2group, C4M2group), dif-ferent cuff pressures when MAP decreased by 30% of the baseline value groups(C1M3group, C2M3group, C3M3group, C4M3group), and different cuff pressures when MAP decreased by 40% of the baseline value groups(C1M4group, C2M4group, C3M4group, C4M4group). Different cuff pressures were 0, 10, 20 and 30 cmH2O.At 2 h of tracheal intubation, the tracheas in the cuff-compressed area were harvested and sliced for examination of the pathological changes of tracheal mucous membrane after haematoxylin and eosin staining(with a light microscope), and the damage to tracheal mucous membrane was scored. Results When at the same low pressure(MAP decreased by 20%, 30% and 40% of the baseline value), the score of damage to tracheal mucous membrane increased with the increasing cuff pressures(P<0.05). When at the same cuff pressure(10, 20 and 30 cmH2O), the score of damage to tracheal mucous membrane in-creased with the increasing MAP(P<0.05). There was interaction between cuff pressure and MAP, F=2.034(P<0.05). Conclusion There is interaction between the effects of hypotension factor and endotra-cheal tube cuff factor on damage to tracheal mucous membrane; hypotension factor can aggravate endotra-cheal tube cuff-induced damage to tracheal mucous membrane of rabbits.
