Objective To investigate obstructive sleep apnea syndrome (OSAS) in patients with aortic dissection (AD). Methods Questionnaire analysis was applied to patients with or without AD according to Berlin questionnaire. Questionnaires were collected and common characters and related symptoms were compared between the two groups. Further comparison on related symptoms was made between the AD group and hypertensive patients in the control group. Results Totally 70 questionnaires were collected with 33 for the AD group (29 males and 4 females) and 37 for the control (29 males and 8 females). The average age (P ＜0.05) was 50.9 years for the AD group (range 32 to 70) and 53.4 years for the control (range 25 to 83). Snoring occurred in 29 AD patients (87. 88% ) and in 22 control patients (59. 46% ) (P ＜ 0. 05 ). Snoring everyday occurred in 19 AD patients (57. 58% ) and in 12 controls (32.43%) (P ＜0.05). Loud snoring was reported from 23 AD patients (69.70%) and 10 controls (27.03%) (P ＜0. 05). Apnea occurred in 15 AD patients (45. 45% ) and 8 controls (21.62%) ( P ＜0. 05). Apnea nearly everyday occurred in 9 AD patients ( 27.27% ) and 5 controls ( 13. 51% ) ( P ＜0. 05). Fatigue after sleep occurred in 23 AD patients (69. 70% ) and 15 controls (40. 54% ) (P ＜0. 05).Fatigue nearly everyday after sleep occurred in 10 AD patients (30. 30% ) and 6 controls ( 16. 22% ) ( P ＜0. 05). Hypertension was found in 28 AD patients ( 84. 85% ) and 20 controls ( 54. 05% ) ( P ＜ 0. 05 ).The average age of hypertensive control were 62 ± 16, greater than that of AD group (P ＜0. 05). In the 20 hypertensive control patients, loud snoring in 7 (35%), lessen than that of AD group (P ＜0.05).Compared with hypertensive controls, AD patients had greater body length ( P ＜ 0. 05 ) and lesser waist-tohip ration (P ＜ 0. 05 ). Conclusions Compared with normal control, OSAS is more common in AD patients.

AIM:To dynamically observe and compare the relative changes of the indexes from the process of acute inflammation to chronic remodeling in asthmatic mice induced by ovalbumin ( OVA) .METHODS:Female BALB/c mice (n=60) were randomly divided into normal control group and asthma group .The mice in asthma group were sensi-tized and challenged by OVA , while the mice in normal group received equal volume of normal saline ( NS) .The challenge was performed for 3 consecutive days from the 21th day to observe the response of acute inflammation , and then the mice in different groups were challenged once per week for 5 weeks.Detailed comparisons of the dynamic changes of cell infiltra-tion, cytokine expression and airway remodeling were conducted .RESULTS:Compared with NS group , the mice in OVA group showed a predominantly eosinophilic infiltration into the airway lumen , increased production of Th 2-type cytokines , secretion of epithelial mucus and deposition of subepithelial collagen .In OVA challenge groups , the levels of inflammatory cells and inflammatory factors were remarkably higher in 24 d group, whereas the most obvious changes of goblet cell hyper-plasia and airway remodeling were observed in 52 d group.CONCLUSION:Acute asthma model is sufficiently induced by 3 consecutive days of OVA challenge protocol , which is accompanied with high levels of inflammatory cells and inflammato-ry factors.The OVA challenge protocol once per week for 5 weeks could induce a chronic asthma model with obvious airway remodeling .

Objective: To explore the emotional and behavioral problems of different only child and multiple child families, and to provide a reference for developing effective parenting styles. Methods: A stratified random cluster sampling method was adopted to investigate 2 647 guardians of preschool children in Tongling City from April to June, 2022. Children s emotional and behavioral problems were evaluated by using the self designed parenting questionnaire and the Children s Strengths and Difficulties Questionnaire (SDQ) parent edition. Results: The abnormal total score detection rate of emotional and behavioral problems of preschool children was 15.5%, and the rate of abnormal peer interaction was the highest (19.5%). In multiple child families, the first born child (17.5%, 20.4%), compared with the second and third child (11.5%, 9.5%), was more likely to exhibit conduct and hyperactivity problems ( χ 2=8.44, 29.75, P <0.01). There were differences in parenting attitudes between only child and multiple child families( χ 2=9.38, P <0.05). The results of the Logistic regression analysis showed that more frequent parent child discussion, the persuasive education and consistent family discipline strategy were negatively related to the emotional and behavioral problems of only children and children in multiple child families ( OR =0.15, 0.49, 0.38; 0.34, 0.40, 0.42, P <0.05). However, harmonious family relationships were only negatively related to emotional and behavioral problems in only children ( OR =0.08, P <0.01), and a higher education level among mothers was negatively related to emotional and behavioral problems in children from multiple child family environments( OR=0.30, 0.45, P <0.05). Conclusion The emotional and behavioral problems are serious of preschool children in Tongling City, the psychological development of the oldest children from multiple child and only child families should be actively followed, as this would help to promote a better understanding of the development of preschool children s physical and mental health.

Objective:To evaluate the effect of esketamine on acute kidney injury (AKI) in the rats with sepsis and the role of autophagy.Methods:Forty SPF healthy adult male Sprague-Dawley rats, weighing 200-240 g, were divided into 5 groups ( n=8 each) by a random number table method: control group (Con group), esketamine group (Con+ Ket group), sepsis group (lipopolysaccharide [LPS] group), sepsis plus esketamine group (LPS+ Ket group), and sepsis plus esketamine plus 3-methyladenine (3MA) group (LPS+ Ket+ 3MA group). The model of AKI was established by intraperitoneal injection of LPS in anesthetized rats.Normal saline 10 ml/kg was intraperitoneally injected in Con group.In Con+ Ket group, normal saline 10 ml/kg was intraperitoneally injected, and 30 min later esketamine 10 mg/kg was injected via the tail vein.LPS 10 mg/kg was intraperitoneally injected in LPS group.In LPS+ Ket group, LPS 10 mg/kg was intraperitoneally injected, and 30 min later esketamine 10 mg/kg was injected via the tail vein.In LPS+ Ket+ 3MA group, LPS 10 mg/kg was intraperitoneally injected, and 30 min later esketamine 10 mg/kg and 3-MA 15 mg/kg were injected via the tail vein.The rats were anesthetized at 24 h after intraperitoneal injection of LPS and then sacrificed, and renal tissues were removed for microscopic examination of the pathological changes which were scored and for determination of contents of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1, interleukin-1beta (IL-1β) and IL-18 (by enzyme-linked immunosorbent assay) and expression of LC3, P62 and Beclin-1 (by Western blot).

Conclusion:Esketamine can reduce AKI and autophagy is involved in the process, which is related to inhibiting the activation of NLRP3 inflammasomes and decreasing inflammatory responses in rats with sepsis.

Objective:To evaluate the role of ErbB2 interacting protein (Erbin) in sepsis-associated encephalopathy (SAE) in mice and the relationship with nod-like receptor thermoprotein domain associated protein 3 (NLRP3) inflammasomes.Methods:Sixty SPF-grade healthy male wild-type C57BL/6 mice and 60 Erbin (-/-)C57BL/6 mice, aged 8-10 weeks, weighing 20-25 g, were divided into 4 groups ( n=30 each) by a random number table method: wild-type sham operation group (WT+ Sham group), wild-type SAE group (WT+ SAE group), Erbin (-/-) sham operation group (EKO+ Sham group) and Erbin (-/-) plus SAE group (EKO+ SAE group). The model of SAE was established by cecal ligation and perforation in anesthetized mice.Open field test (total distance moved) was performed at 7 days after establishing the model, new object recognition test (recognition index) was performed at 8 days after establishing the model, and Morris water maze test (time of staying at target quadrant) was performed at 10 days after establishing the model.The mice were sacrificed, and hippocampal tissues were removed for microscopic examination of pathologic changes (by HE staining) and for determination of neuron count, expression of NLRP3, caspase-1 and apoptosis-associated speck-like protein containing a CARD (ASC) (by Western blot), the number of NLRP3 positive cells (by immunohistochemistry), and contents of interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α) and IL-18 (by enzyme-linked immunosorbent assay). The cell survival rate was calculated. Results:Compared with group WT+ Sham, the time of staying at target quadrant was significantly shortened, the recognition index and cell survival rate were decreased, the contents of IL-1β, IL-18 and TNF-α and the number of NLRP3 positive cells were increased, and the expression of NLRP3, caspase-1 and ASC was up-regulated in group WT+ SAE ( P<0.05). Compared with group EKO+ Sham, the time of staying at target quadrant was significantly shortened, the recognition index and cell survival rate were decreased, the contents of IL-1β, IL-18 and TNF-α and the number of NLRP3 positive cells were increased, and the expression of NLRP3, caspase-1 and ASC was up-regulated in group EKO+ SAE ( P<0.05). Compared with group WT+ SAE, the time of staying at target quadrant was significantly shortened, the recognition index and cell survival rate were decreased, the contents of IL-1β, IL-18 and TNF-α and the number of NLRP3 positive cells were increased, and the expression of NLRP3, caspase-1 and ASC was up-regulated in group EKO+ SAE ( P<0.05). There was no significant difference in total distance moved between the four groups ( P>0.05). Conclusion:Erbin can exert endogenous protection by inhibiting the activation of NLRP3 inflammasomes in mice with SAE.

Objective:To evaluate the relationship between Erbin and Bax/Bcl-xL-mediated cell apoptosis during sepsis-induced acute kidney injury in mice.Methods:Thirty-two SPF male wild type C57BL/6 mice, 32 SPF male Erbin (-/-) C57BL/6 mice, aged 6-8 weeks, weighing 20-30 g, were divided into 2 groups ( n=16 each) using the random number table method: wild type sham operation group (WT+ Sham group), wild type sepsis group (WT+ S group), Erbin(-/-) sham operation group (EKO+ Sham group), and Erbin(-/-) sepsis group (EKO+ S group). The sepsis model was established using the moderate cecal ligation and puncture (CLP) in anesthetized animals.The survival rates within 7 days after CLP were recorded.The serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-10 (IL-10), IL-1β, creatinine (Cr), blood urea nitrogen (BUN) and lactic dehydrogenase (LDH) were determined at 24 h after CLP.Then the renal tissues were taken for assessment of renal injury which was scored and for determination of the apoptosis rate (by TUNEL) and expression of cleaved-caspase-3, Bcl-xL and Bax (by Western blot).
