Objective:To compare the efficacy of whole blood (WB) versus component therapy (COMP) in the resuscitation of patients with traumatic shock.Methods:A systematic literature search was conducted using PubMed and Embase databases for English literature published from January 2006 to December 2023. Studies on the comparative efficacy of WB versus COMP in resuscitation of patients with traumatic shock were all included. Patients were categorized according to the initial transfusion strategies into WB group and COMP group. Primary outcome indicators were extracted and subjected to meta-analysis, including transfusion requirements after admission (4-hour red blood cell requirement, 4-hour plasma requirement, 4-hour total transfusion volume, 24-hour red blood cell requirement, 24-hour plasma requirement, and 24-hour total transfusion volume), length of hospital stay, length of ICU stay, and mortality rates (early mortality, 24-hour mortality, late mortality, and in-hospital mortality, and 24-hour mortality with multiple variables adjusted).Results:Twenty-seven studies involving 15 176 patients (4 692 patients in WB group and 10 484 in COMP group) were included. Meta-analysis results indicated that the 4-hour red blood cell requirement (SMD=-0.44, 95% CI -0.69, -0.19, P<0.01), 4-hour plasma requirement (SMD=-0.25, 95% CI -0.50, -0.01, P<0.05), 24-hour red blood cell requirement (SMD=-0.22, 95% CI -0.36, -0.09, P<0.01), and 24-hour mortality with multiple variables adjusted ( OR=0.78, 95% CI 0.68, 0.91, P<0.05) were significantly reduced in WB group. No significant differences were observed between the two groups regarding 4-hour total transfusion volume, 24-hour plasma requirement, 24-hour total transfusion volume, length of hospital stay, length of ICU stay, early mortality, 24-hour mortality, late mortality, and total in-hospital mortality ( P>0.05). Conclusions:WB demonstrates certain advantages over COMP in the resuscitation of patients with traumatic shock by reducing 4-hour red blood cell requirement, 4-hour plasma requirement, 24-hour red blood cell requirement, and 24-hour mortality with multiple variables adjusted. However, WB and COMP demonstrate comparable effectiveness in reducing 4-hour total transfusion volume, 24-hour plasma requirement, 24-hour total transfusion volume, early mortality rate, 24-hour mortality rate, late mortality rate, and in-hospital mortality.

Objective:To explore the characteristics of the brain functional networks in children with spastic cerebral palsy (SCP) while at rest and to correlate them with motor functioning.Methods:Thirty-six children with SCP were enrolled as the SCP group, while thirty-four age-matched healthy children were recruited as the control group (the HC group). Functional near-infrared spectroscopy was used to detect changes in the concentration of oxygenated hemoglobin in the children′s cerebral cortex while at rest. The left prefrontal cortex (LPFC), right prefrontal cortex (RPFC), left motor cortex (LMC), and right motor cortex (RMC) were selected as regions of interest. Phase locking values (PLVs) were used to evaluate the strength of functional connectivity (FC) among these brain regions, and graph theory methods were applied to analyze the topological properties of the brain networks. Motor functioning was assessed using the gross motor function measure (GMFM).Results:The analyses of FC strength revealed that the SCP group had significantly weaker FC among all of the regions of interest while at rest compared to the HC group. Their PLVs for LPFC-RPFC, LPFC-RMC, RPFC-RMC and LMC-RMC connectivity were all significantly smaller. Graph theory analysis showed that the SCP group had significantly lower global efficiency (GE) and smaller clustering coefficients (CCs) and network density (D), while their characteristic path lengths were significantly longer. According to the correlation analysis, the PLVs for LMC-RMC connections in the SCP group were positively correlated with their scores on dimensions D and E of the GMFM ( r=0.496 and r=0.579 respectively). GE ( r=0.587 and r=0.642) and CC ( r=0.318 and r=0.759) showed similar significant positive correlations with GMFM dimensions D and E. Conclusions:At rest, the functional networks in the brains of children with SCP exhibit abnormalities closely associated with their motor dysfunction.

Objective:To establish and validate a model predicting the age at which a child with cerebral palsy will be able to walk independently.Methods:Data spanning 2016 to 2020 were collected from the cerebral palsy registration platform to build a database. Then, 70% of the patients were randomly assigned to the modeling group, while the remaining 30% were reserved for validation. Factors such as gender, bilirubin encephalopathy, neonatal asphyxia, extremely low birth weight, early pre-term birth, cerebral palsy type, magnetic resonance classification, gross motor function classification (GMFCS) score before 2 years of age, independent sitting age, ability to sit independently at 2 years of age, sections A through E of the gross motor function measure (GMFM-88), epilepsy, intellectual disability, visual impairment and surgery were analyzed applying Cox univariate regression analysis. The variables highlighted by the univariate regression analysis were included in Cox multivariate regression analyses, and a prediction model for the independent walking of children with cerebral palsy was established. It is presented as a linear graph. The C-statistic and calibration curve were used to evaluate the graph′s discrimination ability and calibration. Net reclassification improvement (NRI) was used to evaluate the linear graph′s net benefit.Results:A total of 807 cases were included in the study, with 565 and 242 in the model and validation groups, respectively. GMFCS score before 2 years of age, cerebral palsy type, independent sitting age, intellectual disability and early pre-term birth were found to be independent predictors of the age of independent walking. The C-statistics for 1-6 year-olds were all >0.8, indicating that the prediction model had good discrimination. The calibration curve showed that the predicted probability of independent walking at 1-4 years old was consistent with the observed probability, while the predicted probability of independent walking at 5-6 years old was higher than the observed probability. NRI suggested that the net benefit of the linear graph prediction model was not less than that of the full-factor model.Conclusion:A linear model was developed which can usefully predict the age of independent walking for children with cerebral palsy.

Objective:To investigate the effect and role of the hepatitis B virus (HBV) on the expression of inhibin (PHB) in the proliferation and survival of hepatocellular carcinoma (HCC) cells.Methods:The expression of PHB in 13 pairs of HBV-infected livers, normal livers and HepG2.2.15 and HepG2 cells was detected by real-time fluorescent quantitative PCR and Western blot. Liver tissues were collected from seven patients with chronic hepatitis B before and after antiviral (tenofovir) treatment, and the expression of PHB was detected by RT-PCR and Western blot. HepG2.2.15 cells were transfected with Pcmv6-AC-GFP-PHB, and control vectors were collected. DNA content was analyzed by flow cytometry. The proliferation level of each cell group was detected using the EdU cell proliferation assay. HepG2.2.15 cells transfected with Pcmv6-AC-GFP-PHB and the control vector were cultured in serum-free medium for 6 days. Apoptosis was measured at the indicated time points using fluorescence-activated cell sorting (FACS)-based Annexin-V/PI double staining.Results:Compared with normal liver tissue, the expression of PHB in HBV-infected liver tissue was down-regulated ( P < 0.01). Compared with HepG2 cells, the expression of PHB in HepG2.2.15 cells was significantly decreased ( P < 0.01). The expression level of PHB in liver tissue after antiviral treatment (tenofovir) was significantly higher than that before treatment ( P < 0.01). Compared with the control vector, the proliferation rate of HepG2.2.15 cells transfected with Pcmv6-AC-GFP-PHB was significantly lower than that of the control vector, and the apoptosis rate of HepG2.2.15 cells transfected with the Pcmv6-AC-GFP-PHB vector was significantly higher than the control vector ( P < 0.01). Conclusion:HBV down-regulates the expression of inhibin to promote the proliferation and survival of hepatocellular carcinoma cells.

Objective:To explore the application of cognitive interview (CI) in intercultural adaptation of the Happiness Scale for Middle-Aged Women (HAS-MW) .Methods:This was a qualitative study. In January 2022, 20 middle-aged women in community of Yanji City were selected by purposive sampling for two rounds of CI, and 10 subjects participated in each round of CI. According to the interview outline, we understood the understanding of the subjects on the HAS-MW items that were preliminarily localized in Chinese. The expert group discussed and revised the items of the scale according to the interview results.Results:In this study, a total of 2 rounds of cognitive interviews were conducted, the age of 10 respondents (P1-P10) in the first round was (49.00±3.55) , and the age of 10 respondents (P11-P20) in the second round was (51.00±3.16) . After the first round, 6 items in HAS-MW were revised due to "imperfect language, grammar and expression". The second round of CI results showed that the respondents understood the contents of the revised scale items and believed that they were consistent with the original scale.Conclusions:Through CI, we can comprehensively understand middle-aged women's understanding of the content of the HAS-MW, effectively find out the cognitive bias caused by improper language expression in the process of the scale's localization, improve the understanding of the content of the scale by the interviewees, which is conducive to intercultural adaptation of the HAS-MW and provides a reference for the revision of the scale.

Objective:To compare the differences in sleep structure between healthy children and children with cerebral palsy (CP) using polysomnography (PSG).Methods:Fifty-six children aged 1-15 hospitalized for cerebral palsy formed the experimental group, while 30 healthy children served as controls. Both groups were given 24-hour PSG, and their sleep structures were compared and analyzed.Results:The incidence of sleep disorders in the children with cerebral palsy (55.4%) was significantly higher than among the healthy children (20.0%). The average sleep latency was significantly higher than among the healthy children, while the duration and the percentage of the rapid eye movement (REM) stage were significantly lower than among the healthy children. Total sleep time [(458.47±95.62)min], sleep efficiency [(74.26±13.63)%], duration of REM [(68.90±42.70)min] and REM percentage [(13.87±7.12)%] were all significantly lower for the children with severe cerebral palsy than for those with mild or moderate disorder. Their time to wake up after falling asleep was significantly longer. Moreover, the duration of REM and the REM percentage of children with dyskinetic cerebral palsy were significantly lower than for those with spastic cerebral palsy.Conclusions:The incidence of sleep disorders among children with cerebral palsy is higher than among healthy children. They have more difficulty in falling asleep and have a shorter REM stage. Children with severe cerebral palsy and involuntary cerebral palsy have more sleep problems.
