ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Cholesterol (CH) plays a crucial role in enhancing the membrane stability of drug delivery systems (DDS). However, its association with conditions such as hyperlipidemia often leads to criticism, overshadowing its influence on the biological effects of formulations. In this study, we reevaluated the delivery effect of CH using widely applied lipid microspheres (LM) as a model DDS. We conducted comprehensive investigations into the impact of CH on the distribution, cell uptake, and protein corona (PC) of LM at sites of cardiovascular inflammatory injury. The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage. Then, the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy. Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma (PPAR-γ) expression in vascular endothelial cells and estrogen receptor alpha (ERα) protein levels in myocardial cells, thereby enhancing LM uptake at cardiovascular inflammation sites. Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V (Apoa5); this may be a major contributing factor to their prolonged circulation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites. It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations. The findings enhance the conceptualization of CH and LM delivery, providing novel strategies for investigating prescription factors' bioactivity.

This paper systematically reviews the phased development history of spacesuit technology across various nations,analyzes its core technologies and breakthroughs,points out the limitations of current spacesuit technology,and explores future directions for spacesuit development in response to deep-space exploration and commercialization demands.It clarifies that spacesuits are transitioning from passive protective gear to intelligent operational platforms,requiring interdisciplinary innovations to overcome key challenges such as lightweight design,adaptive systems,high reliability,and efficient human-machine interaction.

When conducting extravehicular activities under low-gravity conditions like on the moon,the weight of the spacesuit is one of the loads that human body has to bear.The centroid position of the spacesuit will affect the motion control of the human-spacesuit system.In order to reveal the influence of the centroid position of the lunar spacesuit on human motion under lunar-gravity,a suspended 1/6 gravity simulation system was used for the experiment.When subjects were under different load centroids which include front and back on sagittal plane,left and right on coronal plane,up and down on cross-section plane,near to coordinate origin,the postures and plantar pressures of subjects during three typical movements:standing,single-knee standing and walking were captured.Inverse dynamics solution is adopted to analyze the joint torques of human body in above conditions.Combined with the subjective evaluation,the appropriate load centroid area was analyzed by comparative.The experiment shows that,human is non-sensitive to the up and down change of load centroid,the after is back change,the front and right load centroid are the mostly avoided.The results obtained by this study will provide a reference for the layout design of the lunar spacesuit.

Objective:To analyze mortality risk factors in patients with severe pneumonia and investigate their varying influences across different time periods.Methods:A total of 134 patients with severe pneumonia admitted to the Emergency Department of Xiang’an Hospital, Xiamen University, between June 2019 and February 2020 were enrolled. All patients were treated in the EICU and followed up for four years. Based on outcomes, they were categorized into a death group ( n=77) and a survival group ( n=57). COX regression analysis was employed to identify mortality risk factors at different time points, while logistic regression analysis was used to assess risk factors influencing mortality during hospitalization, ICU stay, 1-month, and 1-year follow-up periods. Results:Mortality rates were 11.9% ( n=16) during ICU admission, 20.8% ( n=28) during hospitalization, 16.4% ( n=22) within 1 month, and 31.3% ( n=42) within 1 year. By the end of the follow-up, 57.4% ( n=77) of patients had died. Ten mortality risk factors were identified, with the number increasing over time. During ICU admission and hospitalization, significant risk factors included total bilirubin levels, APACHE-II score, invasive ventilation, ARDS, and vasopressor use in the ICU. One-month mortality risk additionally involved bacterial infection. One-year mortality risk further incorporated advanced age and chronic heart failure. By the end of follow-up, acute kidney injury (AKI) during ICU admission also emerged as a contributing factor, while higher body weight was identified as a protective factor. Conclusions:The number of mortality risk factors in severe pneumonia patients increases progressively over time. Early-stage factors during hospitalization and ICU admission exert a stronger impact on short-term mortality, whereas bacterial infection, advanced age, and chronic heart failure become increasingly significant in later stages. These findings highlight the dynamic nature of risk factors and underscore the importance of tailored monitoring and intervention strategies at different disease phases.

Background Ozone (O₃) pollution has gradually become a primary problem of air pollution in recent years. Conducting epidemiological studies on the correlation between O₃ concentration variation and risk of cardiovascular and cerebrovascular diseases can provide reference data for O₃ risk assessment and related policy making. Objective To quantitatively evaluate the effects of O₃ exposure on mortalities of cardiovascular and cerebrovascular diseases among residents in Minhang District, Shanghai. Methods Data of mortalities of cardiovascular and cerebrovascular diseases, air pollutants, and meteorological factors in Minhang District of Shanghai from January 1, 2016 to December 31, 2021 were collected. Associations between O₃ concentration and the mortalities due to total cardiovascular and cerebrovascular diseases, coronary heart disease, and stroke were analyzed by generalized additive models with a quasi Poisson distribution with different lag patterns, such as current day effect (lag0), single-day lag effects (lag1-lag3), and cumulative lag effects (lag01-lag03). The subgroup analyses of age, sex, and season were conducted. Furthermore, temperature was divided into low, middle, and high levels based on the 25th percentile (P₂₅) and the 75th percentile (P₇₅) to perform hierarchical analyses. Increased excess risks (ER) of death from target diseases caused by a 10 µg·m⁻³ increase in daily maximum 8 h concentration of O₃ (O₃-8 h) and their 95% confidence intervals (CI) were used to indicate the effects of O₃. Results The associations between O₃ and the risks of death from cardiovascular and cerebrovascular diseases were statistically significant at lag2, lag3, lag02, and lag03 (P<0.05), with the greatest effect size observed at lag03. The ER values of death from cardiovascular and cerebrovascular diseases in general population, male residents, and people aged 65 years and older, from coronary heart disease in male residents, and from stroke in general population increased by 1.02% (95%CI: 0.36%, 1.69%), 1.40% (95%CI: 0.47%, 2.34%), 0.87% (95%CI: 0.19%, 1.55%), 1.96% (95%CI: 0.49%, 3.44%), and 1.02% (95%CI: 0.07%, 1.98%) for a 10 µg·m⁻³ increase in O₃-8 h concentration at lag03, respectively. During the warm season (from April 1 to September 30), the ER values of death from cardiovascular and cerebrovascular diseases and coronary heart disease per 10 µg·m⁻³ increase in O₃ were 1.18% (95%CI: 0.33%, 3.33%) and 2.69% (95%CI: 0.39%, 5.03%), while the O₃ effect was only statistically significant on cardiovascular and cerebrovascular diseases during the cold season (from October 1 to March 31 next year). At the middle and high temperature levels, the ER values of death from cardiovascular and cerebrovascular diseases increased by 1.63% (95%CI: 0.32%, 2.96%) and 1.14% (95%CI: 0.17%, 2.12%) respectively. The two-pollutant models showed similar results after including other pollutants (carbon monoxide, nitrogen dioxide, sulfur dioxide, fine particulate matter, or inhalable particulate matter). Conclusion Ambient O₃ pollution may increase the mortality risks of cardiovascular and cerebrovascular diseases, coronary heart disease, and stroke in Minhang District of Shanghai.

Small for gestational age (SGA) infants are more likely to experience neurocognitive impairments compared to appropriate for gestational age (AGA) infants. This paper reviews recent research on the neurocognitive development of SGA children. SGA can lead to a "brain-sparing effect" due to growth restriction, which may affect cerebral blood flow and brain structure. However, this does not guarantee normal brain development. Restrictive blood flow can result in changes in brain structure, such as reduced total white matter and gray matter volume in various brain regions, including the cerebral cortex, hippocampus and cerebellum, ultimately leading to decreased head circumference. SGA children also exhibit lower scores in all neurocognitive domains, including intelligence, attention, memory, and executive function. This may result in poor academic performance and an increased risk of social, behavioral, and neurological problems, such as cerebral palsy, epilepsy, visual and hearing impairments, as well as comorbidities like attention deficit hyperactivity disorder(ADHD), autism spectrum disorder(ASD), anxiety, depression, and schizophrenia. Several risk factors for SGA-related neurocognitive impairments have been identified, including gestational hypertension, abnormal gestational weight, smoking, and catch-up growth. Studies have shown that the best interventions to improve cognitive dysplasia include nutrient supplementation, continued breastfeeding, high-quality education, and appropriate early intervention (responsive parenting) are effective in improving cognitive outcomes for SGA children.

Objective:To construct and validate a risk-scoring model for predicting delayed onset of lactogenesis stage Ⅱ (DOL Ⅱ) in mothers separated from their premature infants.Methods:This was a retrospective study. (1) Modeling group: This group enrolled 310 mothers who were separated from their premature infants after delivery at Wuxi Maternal and Child Health Hospital from December 2021 to November 2022. They were further divided into the DOL Ⅱ group (144 cases) and the non-DOL Ⅱgroup (166 cases) according to whether they had DOL Ⅱ or not. Based on the results of multivariate logistic regression analysis, each risk factor was assigned a score, and a risk prediction scoring model was established. (2) Validation group: This group included 130 mothers of premature infants who experienced mother-infant separation after delivery at Wuxi Maternal and Child Health Hospital from December 2022 to March 2023. The area under the receiver operating characteristic (ROC) curve was used to evaluate the discrimination, and the Hosmer-Lemeshow test was used to assess the goodness of fit. The Chi-square test (or Fisher's exact probability test) or Wilcoxon rank sum test were used for inter-group data comparison. Results:This risk prediction scoring model included 10 risk factors [maternal age≥35 years old, hypertensive disorders of pregnancy, anemia, gestational diabetes mellitus, preterm rupture of membrane, start breastfeeding >6 hours, postpartum admission of maternal intensive care unit, cesarean section, score of Edinburgh Postpartum Depression Scale >9.5, postpartum neutrophil-to-lymphocyte ratio ≥4.369, Fatigue Scale-14 ≥7.5, body mass index in the first trimester ≥23.719 kg/m 2, postpartum BMI≥27.661 kg/m 2,and increase of BMI during pregnancy ≥5.393 kg/m 2], with an area under the ROC curve of 0.838 (95% CI: 0.795-0.882, P<0.001), a maximum Yoden index of 0.526, a specificity of 0.825, a sensitivity of 0.701, and an optimal threshold of 4.5. After rounding the score off to the nearest whole number, those with a score≥5 were defined as at high risk of DOL Ⅱ, while those with a score<5 were at low risk. Hosmer-Lemeshow test showed χ2=3.43 and P=0.634. The positive predictive value, the negative predictive value, and the accuracy were 77.7%, 76.1%, and 76.8%, respectively. In the modeling group, 130 out of the 310 cases (41.9%) were predicted to be at high risk by the model with 101 (32.6%) experiencing DOL Ⅱ, while 180 cases (58.1%) were predicted to be at low risk with 43 (13.9%) experiencing DOL Ⅱ. Among the 130 cases in the validation group, 59 (45.4%) were predicted to be at high risk with 39 (30.0%) experiencing DOL Ⅱ, while 71 (54.6%) were predicted to be at low risk with 19 (14.6%) experiencing DOL Ⅱ. The model validation results showed that the area under the ROC curve was 0.774 (95% CI: 0.693-0.855, P<0.001) and the Hosmer-Lemeshow test showed χ2=3.09 and P=0.687, with the positive predictive value of 66.1%, the negative predictive value of 73.2%, and the accuracy of 70.0%. Conclusions:This study preliminarily establishes a risk scoring model for predicting DOL Ⅱ in mothers separated from their premature infants which is of certain predictive value and can provide a reference for developing predictive lactation support measures.

With the progress of society and the continuous improvement of people′s living standards in China, the public′s demand for medical services is becoming increasingly diversified. How to move hospital services forward and improve medical services centered on patients has become a key consideration for hospitals to enhance patients′ sense of medical satisfaction. A certain hospital has established a one-stop patient service hotline, integrating functions such as number inquiry, medical consultation, appointment registration, appointment examination, praise and suggestions, complaint follow-up, etc., injecting a complaint handling management mode, and responding to and solving patient feedback problems in a timely manner. Since the launch of the patient service hotline, it has effectively solved the problems that patients encountered during their visits, effectively reduced the hospital′s complaint rate, and initially formed a service closed-loop management. From March to October 2023, the demand ratio of the 12345 hotline in the hospital has continuously decreased, and was significantly lower than the average level of 22 municipal hospitals in Beijing. In the future, we should further improve the communication skills between doctors and patients, focus on managing appeals and services, and continue to strengthen proactive governance.
