Objective:To explore the influence of the second stage of labor>2 hours of new birth process standards on preventing mother-to-child transmission and delivery outcome among chronic hepatitis B puerperas.Methods:Clinical data of 100 puerperas with hepatitis B virus (HBV) were retrospectively analyzed in Beijing YouAn Hospital from January 1 2014 to December 1 2018. Puerpera with the second stage of labor >2 hours were in observation group, and puerperas with the second stage of labor<2 hours were in control group, 50 cases in each group. The follow-up of two groups was carried out until neonate aged 7 months. This study compared the main outcome measures (the rate of mother-to-child transmission of HBV) and the secondary outcome measures (surgical delivery, rate of lateral perineal incision, blood loss during delivery and 2 hours after delivery, incidence of neonatal asphyxia) between two groups.Results:There was no statistical difference in the number of neonate with positive HBsAg during delivery between two groups ( P>0.05) ; there was no neonate aged 7 months with positive HBsAg between two groups. Numbers of lateral perineal incision, surgical delivery and blood loss during delivery in observation group increased compared with those in control group with statistical differences ( P<0.05) . There were no statistical differences in the incidence of neonatal asphyxia and blood loss 2 hours after delivery between two groups ( P>0.05) . Conclusions:The second stage of labor >2 hours of new birth process standards is carried out without increasing the rate of mother-to-child transmission of hepatitis B, but it increases rates of surgical delivery, lateral perineal incision and blood loss during delivery. We should comprehensively consider and discuss when implementing the new birth process management in hepatitis B puerperas so as to assure the safety of months and infants.

Objective:To analyze the causes of SARS-CoV-2 nosocomial infection among healthcare workers (HCWs) and explore the effective precaution strategies in Emergency Center.Methods:The data of SARS-CoV-2 infected HCWs from January 5 to March 2, 2020 were retrospectively analyzed and compared under different conditions in Emergency Center of Zhongnan Hospital of Wuhan University.Results:Totally 13 SARS-CoV-2 infected HCWs (12 confirmed cases and 1 suspected case) were included in this study. The overall infection rate was 17.8% (13/73). The infection rates in outpatient/rescue room, isolation observation room and isolationin patient ward were 11.8% (4/34), 20.0% (3/15), 25% (6/24), respectively. The infection rate of physician was 13.0% (3/23), and the infection rate of nurse was 20.0% (10/50). All the infected HCWs had the definite exposure with confirmed or suspected COVID-19 patients. One asymptomatic cases were identified by laboratory findings of SARS-CoV-2 infection screening. There was no new confirmed SARS-CoV-2 infected HCWs after February 5, 2020. All the infected HCWs were cured.Conclusions:Under the epidemic of COVID-19, HCWs of Emergency Center have a high risk of occupational exposure and infection, especially for staffs working in COVID-19 isolation units. Scientific prevention and control management can effectively reduce the risk of SARS-CoV-2 infections and ensure the occupational safety for HCWs in Emergency Center.

Long noncoding RNAs (lncRNAs) are involved in vital life processes of gene expression, epigenetic regulation and X-chromosome inactivation. lncRNAs are also closely associated with tumor initiation and progression. Moreover, lncRNAs may enter human circulation system in the form of microvesicle or exosome, or in combination with RNA binding protein. Interestingly, the circulating lncRNAs are widely existed in body fluids, such as blood and urine. We review the origin of circulating lncRNAs, and the detection methods as potential biomarkers. We focus on the early diagnosis value of circulating lncRNAs as tumor biomarkers in lung, breast, gastric, liver, colorectal and prostate cancers. Compared with the traditional biomarkers, the circulating lncRNAs show the unique advantages and clinical values as novel biomarkers.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.

Objective:To investigate the effects of Porphyromonas gingivalis derived outer membrane vesicles (Pg OMV) on osteoclast differentiation of macrophages and its underlying mechanisms. Methods:The morphology and the size distribution of Pg OMV were analyzed by transmission electron microscopy and nanoparticle tracing analysis, respectively. The osteoclast precursors were treated with 1, 3 and 10 mg/L Pg OMV (1, 3 and 10 mg/L OMV treatment group) or phosphate buffer solution (PBS)(control group). The formation of osteoclasts was analyzed by tartrate-resistant acid phosphase (TRAP) staining and F-actin staining and real-time quantitative PCR (RT-qPCR) were used to detect the expression of Fos and matrix metallopeptidase 9 (MMP9). Polymyxin B (PMB) was used to block lipopolysaccharide (LPS) and then Pg OMV was used to treat osteoclast precursor (PMB-OMV treatment group), and OMV treatment group was used as control. TRAP and F-actin staining were used to observe the formation of osteoclasts and actin rings. The effect of Pg OMV on the expression of Toll-like receptor (TLR) 2 and TLR4 in preosteoclasts was detected by Western blotting. The osteoclast precursors were pretreated with 10, 50, 100 and 200 μmol/L C29, an inhibitor of TLR2, and then treated with Pg OMV(OMV+10, 50, 100 and 200 μmol/L C29 treatment group) and OMV treatment group without C29 pretreatment was control. TRAP and F-actin staining were used to observe the formation of osteoclasts and actin rings. The osteoclast precursor cells were treated with OMV (OMV treatment group) and OMV incubated with PMB (PMB-OMV treatment group) and the expression of TLR2 in osteoclast precursor was detected by Western blotting.Results:Pg OMV showed classical vesicular structures, and the average particle size of Pg OMV were 179.2 nm. A large number of actin rings were observed in the 3 and 10 mg/L OMV treatment groups. The percentages of TRAP-positive osteoclast area in 3 mg/L OMV treatment group [(22.6±2.1)%] and 10 mg/L OMV treatment group [(32.0±2.3)%] were significantly increased compared with control group [(4.9±0.5)%] ( P<0.001). Compared with the control group (1.000±0.029), the mRNA relative expression of Fos in 3 mg/L OMV treatment group (1.491±0.114) and 10 mg/L OMV treatment group (1.726±0.254) was significantly increased ( P=0.013, P=0.001). Compared with the control group (1.007±0.148), the mRNA relative expression of MMP9 in the group of 10 mg/L OMV (2.232±0.097) was significantly increased ( P<0.001). Actin ring formation was less in PMB-OMV treatment groups than in OMV treatment groups. The proportion of TRAP-positive osteoclasts area [(14.8±3.8)%] in PMB-OMV treatment group was significantly lower than OMV treatment group [(31.5±6.7) %] ( P=0.004). The relative expression of TLR2 in OMV treatment group (1.359±0.134) was significantly higher than that in the control group (1.000±0.000) ( t=4.62, P=0.044). Compared with the OMV treatment group [(29.4±1.7)%], 50, 100 and 200 μmol/L C29 significantly decreased the formation of osteoclasts [(24.0±1.7)%, (18.5±2.1)%, (9.1±1.3) %] ( P=0.026, P<0.001, P<0.001). TLR2 protein expression in PMB-OMV group (0.780±0.046) was significantly lower than that in OMV group (1.000±0.000)( t=8.32, P=0.001). Conclusions:Pg OMV can promote osteoclast differentiation by carrying LPS, TLR2 plays an important role in Pg OMV mediated osteoclast differentiation.
