Objective:
Hundreds of countries have implemented lockdown policies to slow the spread of coronavirus disease-2019 (COVID-19), but the impact of these measures on maternal mental health is not well understood.
Methods:
This study integrated a stress-process model to examine the pathways from lockdown-related stressors to prenatal psychological outcomes, with COVID-19 coping strategies (COP) and self-efficacy in managing negative affect (NEG) as mediators and lockdown duration, hours on pandemic-related information, and number of pregnancies as moderators. Pregnant women in Shanghai completed the Regulatory Emotional Self-Efficacy Scale, COVID-19 Coping Scale, Depression, Anxiety, and Stress Scale-21. Structural equation modeling (SEM) was used to test and modify the hypothetical model, and moderated mediation and slope analyses were undertaken.
Results:
In the final SEM demonstrating satisfactory fit, three stressors—decreased household income, insufficient daily supplies, and acquired infections—showed positive direct relationships with NEG and COP. Acquired infections, NEG, and COP were identified as direct predictors of mental health outcomes. The relationship between these three stressors and mental health was mediated by NEG and COP. Additionally, the number of pregnancies moderated the mediating effect of COP; this effect was more pronounced among first-time pregnant women than those with multiple pregnancies.
Conclusion
This study provides insights into how lockdown measures impact psychological outcomes in pregnant women quarantined at home. Interventions aimed at increasing coping strategies may be more effective for primiparous women during future public health emergencies.

Objective There is limited research on the combined use of multiple drugs in the prevention and treatment of radiation-induced oral mucositis (RTOM). This study aims to investigate the synergistic effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF), Kangfuxin Liquid, and vitamin B12 via mouthwash on RTOM, and provide a novel approach for the prevention and treatment of acute RTOM. Methods A total of 82 patients with head and neck cancer who underwent radical radiotherapy were randomly divided into four groups: a control group (vitamin B12, 20 cases), observation group 1 (rhG-CSF + vitamin B12, 20 cases), observation group 2 (Kangfuxin Liquid + vitamin B12, 21 cases), and observation group 3 (rhG-CSF + Kangfuxin Liquid + vitamin B12, 21 cases). After 4 weeks of therapy, the therapeutic effects of the four groups were compared. Results Compared to the control group, there was no statistically significant difference in the incidence of RTOM. However, the incidence of severe RTOM was significantly reduced in the observation groups, following the order of observation group 1 (20.00%) > observation group 2 (14.28%) > observation group 3 (9.52%). The initiation period of RTOM in observation group 3 was 24 days, exhibiting a considerable delay in comparison to the control group (16 days), observation group 1 (18 days), and observation group 2 (22 days). The levels of pain experienced by the groups receiving combined treatments were significantly reduced compared to the control group. Observation group 3 exhibited the most effective pain reduction. Conclusion The combined administration of rhG-CSF, Kangfuxin Liquid, and vitamin B12 can prevent radiation-induced oral mucosal injury and promote mucosal healing. This regimen represents an effective strategy for the prevention and treatment of acute RTOM.

This study aims to explore the pharmacodynamic material basis of Jinbei Oral Liquid(JBOL) against idiopathic pulmonary fibrosis(IPF) based on serum pharmacochemistry and network pharmacology. The ultra-high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UHPLC-Q-TOF-MS/MS) technology was employed to analyze and identify the components absorbed into rat blood after oral administration of JBOL. Combined with network pharmacology, the study explored the pharmacodynamic material basis and potential mechanism of JBOL against IPF through protein-protein interaction(PPI) network construction, "component-target-pathway" analysis, Gene Ontology(GO) functional enrichment, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis. First, a total of 114 compounds were rapidly identified in JBOL extract according to the exact relative molecular mass, fragment ions, and other information of the compounds with the use of reference substances and a self-built compound database. Second, on this basis, 70 prototype components in blood were recognized by comparing blank serum with drug-containing serum samples, including 28 flavonoids, 25 organic acids, 4 saponins, 4 alkaloids, and 9 others. Finally, using these components absorbed into blood as candidates, the study obtained 212 potential targets of JBOL against IPF. The anti-IPF mechanism might involve the action of active ingredients such as glycyrrhetinic acid, cryptotanshinone, salvianolic acid B, and forsythoside A on core targets like AKT1, TNF, and ALB and thereby the regulation of multiple signaling pathways including PI3K/AKT, HIF-1, and TNF. In conclusion, JBOL exerts the anti-IPF effect through multiple components, targets, and pathways. The results would provide a reference for further study on pharmacodynamic material basis and pharmacological mechanism of JBOL.

OBJECTIVE:
To explore the morphological characteristics of the postero-superior protuberance of the calcaneus and to explore its relationship with Haglund malformation.
METHODS:
Ankle lateral X-ray films of 391 hospitalized patients between May 2021 and June 2024 were retrospectively collected. The morphological parameters of the postero-superior protuberance of the calcaneus were measured, including the length of the base, the height of the base, and the tip angle of the postero-superior protuberance of the calcaneus, and the morphological types were classified according to the above parameters, including the peak type, the hill type, and the flat type. The related parameters of Haglund malformation were measured, including Fowler-Philipp angle (FPA), calcaneal pitch angle (CPA), parallel pitch line (PPL), Chauveaux-Liet angle (CLA), and X/Y ratio (total calcaneal length/length of greater tuberosity of calcaneus). The differences of the morphological parameters of the postero-superior protuberance of the calcaneus and the related indicators of Haglund deformity among the three types and between the males and the females were compared and analyzed, and the differences of the positive numbers of the related indicators of Haglund deformity among the three types were compared.
RESULTS:
According to the morphological parameters of the postero-superior protuberance of the calcaneus, there were 64 cases of peak type, 245 cases of hill type, and 82 cases of flat type. There was no significant difference in the length of the base of the postero-superior protuberance of the calcaneus, CPA, CLA, and X/Y ratio among the three types ( P>0.05). Among the three types, the peak type had the largest FPA and the flat type had the smallest ( P<0.05); the peak type had the smallest tip angle of the postero-superior protuberance of the calcaneus and the flat type had the largest ( P<0.05); the positive rate of PPL in the hill type was significantly higher than that in the peak type and flat type ( P<0.05); the height of the base of the postero-superior protuberance of the calcaneus in the flat type was the smallest ( P<0.05). FPA, CPA, CLA, PPL, and X/Y ratio were positive in 2, 42, 172, 142, and 77 patients, respectively. There was no significant difference in the number of positive Haglund deformity indicators among the three types ( P>0.05). There was no significant difference between male and female patients in the tip angle of the postero-superior protuberance of the calcaneus, FPA, the positive rate of PPL, and X/Y ratio ( P>0.05). The length and the height of the base of the postero-superior protuberance of the calcaneus, CPA, and CLA in male patients were significantly higher than those in female patients ( P<0.05).
CONCLUSION
The postero-superior protuberance of the calcaneus can be divided into three types: the peak type, the hill type, and the flat type. The peak type is more likely to suffer from Haglund deformity, and the males are more likely to suffer from Haglund deformity than the females.

OBJECTIVE:
To investigate the feasibility and prognostic implications of assessing volume status during early fluid resuscitation in septic patients based on estimated plasma volume status (ePVS).
METHODS:
A prospective study was conducted. Patients with sepsis admitted to intensive care unit (ICU) of the First Affiliated Hospital of Kunming Medical University from March to December in 2023 were enrolled. The general information and laboratory indicators at ICU admission were recorded, and ePVS, sequential organ failure assessment (SOFA) score, acute physiology and chronic health status evaluation II (APACHE II) score were calculated. The vital signs, arterial blood gas analysis and volume status related indicators before liquid resuscitation (T0h) and 3 hours (T3h) and 6 hours (T6h) of fluid resuscitation were recorded. The diameter and variability of the inferior vena cava (IVC) were measured by ultrasound, and ePVS, percentage change value of estimated plasma volume status (ΔePVS%), difference in central venous-to-arterial partial pressure of carbon dioxide (Pcv-aCO2), and lactate clearance rate (LCR) were calculated. Patients were divided into sepsis group and septic shock group based on the diagnosis at ICU admission, and septic patients were subdivided into survival group and death group based on their 28-day survival status. The differences in clinical data between the groups were compared. The correlation between ePVS or ΔePVS% and volume status related indicators during early liquid resuscitation was analyzed by Spearman rank sum correlation test. The predictive value of each variable for 28-day survival in patients with sepsis was analyzed by receiver operator characteristic curve (ROC curve), and 28-day death risk factors were analyzed by Logistic regression method.
RESULTS:
Fifty-four septic patients were enrolled in the final analysis, including 17 with sepsis and 37 with septic shock; 34 survived at 28 days and 20 died, with a 28-day survival rate of 63.0%. Compared with the sepsis group, the septic shock group had a lower venous ePVS at ICU admission [dL/g: 4.96 (3.67, 7.15) vs. 7.55 (4.36, 10.07), P < 0.05]. Compared with the death group, the survival group had higher T6h arterial and venous ΔePVS%, and albumin [Alb; T6h arterial ΔePVS% (%): 11.57% (-1.82%, 31.35%) vs. 0.48% (-5.67%, 6.02%), T6h venous ΔePVS%: 9.62% (3.59%, 25.75%) vs. 1.52% (-9.65%, 7.72%), Alb (g/L): 27.57±4.15 vs. 23.77±6.97, all P < 0.05], lower SOFA score, APACHE II score, AST, T0h Lac, and T3h and T6h norepinephrine dosage [SOFA score: 9.00 (8.00, 10.00) vs. 11.50 (9.25, 14.50), APACHE II score: 18.00 (14.75, 21.25) vs. 25.50 (21.00, 30.00), AST (U/L): 34.09 (23.20, 56.64) vs. 79.24 (25.34, 196.59), T0h Lac (mmol/L): 1.75 (1.40, 2.93) vs. 3.25 (2.33, 5.30), norepinephrine dosage (mg): 0.98 (< 0.01, 3.10) vs. 4.60 (1.05, 8.55) at T3h, 1.82 (0.38, 5.30) vs. 8.20 (2.80, 17.73) at T6h, all P < 0.05]. While there were no significantly differences in other basic data and ePVS at all of the time points before and after resuscitation between the two groups. Correlation analysis showed that T6h venous ePVS was significantly positively correlated with T6h IVC variability in septic patients (r = 0.360, P < 0.05), T0h arterial ePVS was significantly negatively correlated with T3h and T6h liquid intake volume (r1 = -0.367, r2 = -0.280, both P < 0.05), and venous ePVS at ICU admission was significantly positively correlated with NT-proBNP at ICU admission (r = 0.409, P < 0.05). T6h venous ΔePVS% was significantly positively correlated with T3h liquid intake volume and T6h LCR (r1 = 0.286, r2 = 0.286, both P < 0.05), and significantly negatively correlated with T6h urine volume and T6h change value of Pcv-aCO2 (ΔPcv-aCO2; r1 = -0.321, r2 = -0.371, both P < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) of T6h venous ΔePVS% for predicting 28-day survival in septic patients was 0.726 [95% confidence interval (95%CI) was 0.578-0.875, P = 0.006], with a sensitivity of 82.4%, a specificity of 60.0%, and an optimal cut-off value of 3.09%. Binary multifactorial Logistic regression analysis showed that an increase in T6h venous ΔePVS% was a protective factor for 28-day death in patients with sepsis on early fluid resuscitation [odds ratio (OR) = 0.900, 95%CI was 0.834-0.972, P = 0.007].
CONCLUSIONS
ePVS may have potential for assessing the volume status of septic patients during early fluid resuscitation. The ΔePVS% during early fluid resuscitation may help to identify septic patients with a poor prognosis.

Objective:To evaluate the effect of hydrogen on lipopolysaccharide (LPS) and nigericin-induced pyroptosis in macrophages and the role of long non-coding RNA (lncRNA) nuclear-enriched abundant transcript 1 (NEAT1).Methods:Human monocyte-derived macrophages THP-1 cells were cultured in vitro and divided into 4 groups ( n=25 each) using a random number table method: control group (group C), LPS and nigericin group (group LN), hydrogen-rich medium+ LPS and nigericin group (group H+ LN), and lentiviral transfection+ hydrogen-rich medium+ LPS-nigericin group (group LV+ H+ LN). THP-1 cells were cultured in the common culture medium for 24 h in group C. LPS at a final concentration of 100 ng/ml and nigericin 10 μmol/L were added to the culture medium, and the cells were incubated for 24 h in group LN. In group H+ LN, the culture medium was replaced with 0.6 mmol/L hydrogen-rich medium, then LPS at a final concentration of 100 ng/ml and nigericin 10 μmol/L were immediately added, and the cells were incubated for 24 h. In group LV+ H+ LN, THP-1 cells over-expressing NEAT1 stably after being transfected with lentivirus were used, then LPS at a final concentration of 100 ng/ml and nigericin 10 μmol/L were immediately added, and the cells were incubated for 24 h. Cell viability was detected by CCK-8 assay. Lactic dehydrogenase (LDH) release was assessed by colorimetric method. The amount of LDH released was measured by colorimetry. The concentrations of interleukin-1beta (IL-1β) and IL-18 in culture medium were measured by enzyme-linked immunosorbent assay. The pyroptotic rate was detected by flow cytometry. The expression of nucleotide-binding oligomerization domain-like receptor-containing pyrin domain 3 (NLRP3), apoptosis-associated speck-like protein (ASC), caspase-1 and gasdermin D (GSDMD) was detected by Western blot. The expression of NEAT1 gene was determined by quantitative real-time polymerase chain reaction. Results:Compared with group C, the cell viability was significantly decreased, the amount of LDH released, concentrations of IL-1β and IL-18, and pyroptotic rate were increased, and the expression of NEAT1 gene, NLRP3, ASC, caspase-1 and GSDMD was up-regulated in group LN ( P<0.05). Compared with group LN, the cell viability was significantly increased, the amount of LDH released, concentrations of IL-1β and IL-18, and pyroptotic rate were decreased, and the expression of NEAT1 gene, NLRP3, ASC, caspase-1 and GSDMD was down-regulated in group H+ LN ( P<0.05). Compared with group H+ LN, the cell viability was significantly decreased, the amount of LDH released, concentrations of IL-1β and IL-18, and pyroptotic rate were increased, and the expression of NEAT1 gene, NLRP3, ASC, caspase-1 and GSDMD was up-regulated in group LV+ H+ LN ( P<0.05). Conclusions:Hydrogen can ameliorate LPS and nigericin-induced pyroptosis in macrophages, and the mechanism may be associated with down-regulating the expression of lncRNA NEAT1.
