ABSTRACT

ObjectiveTo investigate the patterns of changes in routine blood parameters, thyroid hormone levels, and their correlations with thyroid peroxidase antibodies (TPOAb) among women at different stages of pregnancy, so as to provide a theoretical basis for maternal and child health care and diagnosis and treatment. MethodsA total of 732 pregnant women at different stages of pregnancy who underwent health examinations at the First Maternity and Infant Hospital affiliated to Tongji University from May 2020 to August 2022 were selected as the observation group. The group comprised 245 women in the first trimester (≤12 weeks), 247 women in the second trimester (between13 and 27 weeks) and 240 women in the third trimester (≥28 weeks). Additionally, 240 non-pregnant, healthy women of child-bearing age who conducted their health checkups in the same hospital were selected as the control group. All the research subjects were required to provide peripheral venous blood samples to measure hemoglobin (Hb), standard deviation of red blood cell distribution width (RDW-SD), coefficient of variation of red blood cell distribution width (RDW-CV), platelet (Plt) count, platelet distribution width (PDW), as well as thyroid stimulating hormone (TSH), total thyroxine (TT4), total triiodothyronine (TT3), free thyroxine (FT4), free triiodothyronine (FT3), and TPOAb. The results were statistically analyzed. ResultsWith advancing gestational age, Hb levels were significantly lower in the second and third trimesters than in the first trimester and the control group (F=68.25, P<0.001), while RDW-SD and RDW-CV were significantly higher (F=41.34, P<0.001; F=3.64, P=0.012). Plt levels throughout pregnancy were significantly lower than that in the control group (F=43.21, P<0.001). TSH levels were significantly lower in the first and second trimesters than in the control group (Z=53.49, P<0.001), but gradually increased with gestational age. TT3 and TT4 levels were significantly higher than those in the control group throughout pregnancy (F=148.25, P<0.001; F=210.83, P<0.001), while FT3 and FT4 levels were significantly lower in the second and third trimesters than in the first trimester and the control group (F=42.95, P<0.001; F=101.73, P<0.001). The abnormal rate of TPOAb was significantly higher than that in the control group throughout pregnancy (χ2=25.61, P<0.001). Among pregnant women, those with TPOAb positivity had significantly higher TSH levels and RDW-CV than those with TPOAb negativity (Z=5.70, P<0.001; t=2.39, P=0.018). ConclusionThe levels of Hb, Plt, and thyroid hormones in pregnant women are closely related to gestational age. With increasing gestational age, the abnormal rate of TPOAb decreases, but the TSH levels and RDW-CV of TPOAb positive pregnant women are higher, requiring clinical attention and screening to improve maternal and child health.

ABSTRACT

Background/Aims@#Chemoresistance is a common event after cancer chemotherapy, which is associated with the deregulation of circular RNAs (circRNAs). The objective of this study was to clarify the role of circ-LDLRAD3 in cisplatin (DDP)-resistant gastric cancer (GC). @*Methods@#The expression of circ-LDLRAD3, miR-588, and SRY-box transcription factor 5 (SOX5) mRNA was detected by quantitative real-time polymerase chain reaction. Cell viability and the half maximal inhibitory concentration (IC 50 ) value were measured by CCK8 assay. Cell proliferation was assessed by colony formation and EdU assays. Cell apoptosis and cell invasion were assessed by flow cytometry assay and transwell assay, respectively. The expression of SOX5 protein was detected by Western blotting. A xenograft model was established to verify the role of circ-LDLRAD3 in vivo. Exosomes were isolated by differential centrifugation and identified by transmission electron microscopy and the expression of exosome-related proteins. @*Results@#circ-LDLRAD3 was overexpressed in DDP-resistant GC tissues and cells. circ-LDL-RAD3 knockdown decreased the IC 50 of DDP-resistant cells and suppressed cell proliferation, survival and invasion. miR-588 was a target of circ-LDLRAD3, and miR-588 inhibition attenuated the inhibition of DDP resistance, proliferation, survival and invasion in DDP-resistant GC cells caused by circ-LDLRAD3 knockdown. SOX5 was a target of miR-588, and the inhibition of the DDP resistance, proliferation, survival and invasion of DDP-resistant GC cells by miR-588 restoration was largely rescued SOX5 overexpression. circ-LDLRAD3 knockdown inhibited DDP resistance and tumor growth in vivo. circ-LDLRAD3 was overexpressed in exosomes isolated from DDP-resistant GC cells. @*Conclusions@#circ-LDLRAD3 knockdown reduced DDP resistance and blocked the malignant development of DDP-resistant GC by modulating the miR-588/SOX5 pathway.

ABSTRACT

Objective: To identify the predisposing factors, clinical characteristics, and risk factors of disease progression to establish a novel predictive survival model and evaluate its application value for hepatitis B virus-related acute-on-chronic liver failure. Methods: 153 cases of HBV-ACLF were selected according to the guidelines for the diagnosis and treatment of liver failure (2018 edition) of the Chinese Medical Association Hepatology Branch. Predisposing factors, the basic liver disease stage, therapeutic drugs, clinical characteristics, and factors affecting survival status were analyzed. Cox proportional hazards regression analysis was used to screen prognostic factors and establish a novel predictive survival model. The receiver operating characteristic curve (ROC) was used to evaluate predictive value with the Model for End-Stage Liver Disease (MELD) and the Chronic Liver Failure Consortium Acute-on-Chronic Liver Failure score (CLIF-C ACLF). Results: 80.39% (123/153) based on hepatitis B cirrhosis had developed ACLF. HBV-ACLF's main inducing factors were the discontinuation of nucleos(t)ide analogues (NAs) and the application of hepatotoxic drugs, including Chinese patent medicine/Chinese herbal medicine, non-steroidal anti-inflammatory drugs, anti-tuberculosis drugs, central nervous system drugs, anti-tumor drugs, etc. 34.64% of cases had an unknown inducement. The most common clinical symptoms at onset were progressive jaundice, poor appetite, and fatigue. The short-term mortality rate was significantly higher in patients complicated with hepatic encephalopathy, upper gastrointestinal hemorrhage, hepatorenal syndrome, and infection (P < 0.05). Lactate dehydrogenase, albumin, the international normalized ratio, the neutrophil-to-lymphocyte ratio, hepatic encephalopathy, and upper gastrointestinal bleeding were the independent predictors for the survival status of patients. The LAINeu model was established. The area under the curve for evaluating the survival of HBV-ACLF was 0.886, which was significantly higher than the MELD and CLIF-C ACLF scores (P < 0.05), and the prognosis was worse when the LAINeu score ≥ -3.75. Conclusion: Discontinuation of NAs and the application of hepatotoxic drugs are common predisposing factors for HBV-ACLF. Hepatic decompensation-related complications and infection accelerate the disease's progression. The LAINeu model can predict patient survival conditions more accurately.

ABSTRACT

Objective: To investigate the current situation of job involvement of nurses in military hospitals in Henan Province and analyze the influencing factors, so as to provide reference for improving the level of job involvement of military nurses. Methods: In February 2022, the employed nurses of 4 military hospitals in Henan Province were investigated by convenient sampling method. A total of 663 questionnaires were collected, including 632 valid questionnaires, with an effective recovery rate of 95.32%. The self-designed questionnaire was used to investigate the basic information of nurses, the Job Involvement Scale was used to investigate the job involvement of nurses, the Emotional Labor Scale for Nurses was used to investigate nurses' emotions, and the Work-Family Conflict Scale was used to investigate the work-family conflict of nurses. Independent sample t-test and univariate analysis of variance were used to compare the job involvement of military employed nurses with different demographic characteristics, Pearson correlation analysis was used to explore the correlation between emotional labor, work-family conflict and job involvement, and hierarchical regression analysis was used to explore the impact of relevant variables on the job involvement of military employed nurses. Results: The total average score of job involvement of military employed nurses was (3.68±1.13), and the scores of vitality, dedication and focus were (3.64±1.15), (3.74±1.25) and (3.67±1.21) respectively. The total score of emotional labor of nurses was 33-80 (62.95±8.12), with an average score of (3.93±0.51). The total score of work-family conflict was 18-94 (55.16±13.53), with an average score of (3.06±0.75). Professional emotional regulation, patient-centered emotional inhibition and standardized emotional play were positively related to the job involvement (r=0.46, 0.41, 0.22, P<0.01). Time-based conflict, stress-based conflict and behavior-based conflict had negative correlation with the job involvement (r=-0.12, -0.23, -0.20, P<0.01). In hierarchical regression analysis, after controlling demographic variables, emotional labor and work-family conflict accounted for 17.2% and 4.2% of the variation of job involvement. Conclusion: The job involvement of military employed nurses tends to be at a moderate level. Emotional labor and work-family conflict can significantly affect their job involvement.

ABSTRACT

Objective:To report the experience of using CT-guided cochlear implant surgery in difficult cases such as severe inner ear deformities and anatomical abnormalities, and to discuss the application value of intraoperative CT-assisted localization in difficult cases of cochlear implant surgery. Methods:Retrospectively analyzed the clinical data of 23 cases of difficult cochlear implant surgery cases completed by our team with the assistance of intraoperative CT, and collected their medical data, including preoperative imaging manifestations, surgical conditions, and intraoperative imaging images for evaluation. Results:During the study period, 23 difficult cases(27 ears) underwent cochlear implantation under the guidance of intraoperative CT, and 4 cases were bilaterally implanted. Including 6 cases of incomplete segmentation type Ⅰ(IP-Ⅰ), 1 case of incomplete segmentation type Ⅱ(IP-Ⅱ), 10 cases of incomplete segmentation type Ⅲ(IP-Ⅲ), 3 cases of common cavity deformity(CC) and 3 cases of cochlear ossification after meningitis. Facial nerve anatomy was abnormal in 9 cases, cerebrospinal fluid "blowout" was serious in 14 cases, electrode position was abnormal in 3 cases requiring intraoperative adjustment of electrode position, anatomical difficulties required intraoperative CT to assist in finding anatomical landmarks in 2 cases, and electrodes were not fully implanted in 3 cases. Conclusion:When faced with difficult cases with challenging and complex temporal bone anatomy, intraoperative CT can accurately evaluate the electrode position and provide intraoperative anatomical details, allowing immediate adjustment of the electrode position if necessary, providing safety guarantee for difficult cases of cochlear implant surgery and ensure accurate implantation of electrodes.

ABSTRACT

OBJECTIVE@#To observe the ferroptosis triggered by in different pathways during cecal ligation and puncture (CLP)-induced liver injury in septic mice, and to investigate whether mitochondrial aldehyde dehydrogenase 2 (ALDH2) can alleviate sepsis-induced liver injury by inhibiting ferroptosis.@*METHODS@#Sixty 8-week-old male C57BL/6J mice were randomly divided into sham operation group (Sham group), CLP group, ferroptosis inhibitor ferrostain-1 (Fer-1) group, ALDH2-specific agonist Alda-1 group, iron chelator deferasirox Fe3+ chelate (DXZ) group and dimethyl sulfoxide (DMSO) group, with 10 mice in each group. The septic liver injury was induced by CLP in mice model. In the Sham group, only laparotomy was performed without ligation and puncture of the cecum. 10 mL/kg 5% DMSO, 5 mg/kg Fer-1, 50 mg/kg DXZ and 10 mg/kg Alda-1 were injected intraperitoneally 1 hour before CLP in the DMSO, Fer-1, DXZ and Alda-1 groups respectively. At 24 hours after operation, eyeball blood and liver tissue were collected from anesthetized mice. The hepatic structure and inflammatory infiltration were observed by hematoxylin-eosin (HE) staining. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) in serum, the levels of hepatic malondialdehyde (MDA), superoxide dismutase (SOD) and reactive oxygen species (ROS) were detected. Western blotting was used to detect the protein expressions of ALDH2, ferroptosis-related proteins glutathione peroxidase 4 (GPX4), ferroptosis suppressor protein 1 (FSP1) and transferrin receptor 1 (TFR1) in liver tissue.@*RESULTS@#Compared with Sham group, the mice in CLP group showed varying degrees of congestion, disorganized hepatocyte arrangement, inflammatory cell infiltration at 24 hours after operation. Compared with the CLP group, the mice in the Fer-1 group, DXZ group and Alda-1 group liver morphology, liver injury and inflammatory cell infiltration was improved. Compared with Sham group, the serum levels of ALT and AST, the contents of MDA and ROS, and the expression of TFR1 protein in CLP group were significantly increased, while the activity of SOD and the expressions of ALDH2, GPX4 and FSP1 protein in CLP group were significantly decreased. Compared with CLP group, serum ALT and AST levels in Fer-1, DXZ and Alda-1 groups were significantly decreased [ALT (U/L): 45.76±10.81, 37.30±2.98, 36.40±12.75 vs. 73.06±12.20, AST (U/L): 61.57±2.69, 52.41±6.92, 56.05±8.29 vs. 81.59±5.46, all P < 0.05], and the contents of MDA, ROS and TFR1 protein expression in liver tissue were significantly decreased [MDA (μmol/L): 0.60±0.10, 0.57±0.18, 0.83±0.39 vs. 1.61±0.30, ROS (fluorescence intensity): 270.34±9.64, 276.02±62.33, 262.05±18.55 vs. 455.38±36.07, TFR1/GAPDH: 0.90±0.04, 1.01±0.09, 0.55±0.08 vs. 1.18±0.06, all P < 0.05], and the SOD activity and ALDH2, GPX4 and FSP1 protein expressions in liver tissue were significantly increased [SOD (kU/g): 88.77±8.20, 88.37±4.47, 93.43±7.24 vs. 50.27±3.57, ALDH2/GAPDH: 1.10±0.15, 1.02±0.07, 1.14±0.07 vs. 0.70±0.04, GPX4/GAPDH: 1.02±0.12, 0.99±0.08, 1.05±0.19 vs. 0.71±0.10, FSP1/GAPDH: 1.06±0.24, 1.02±0.08, 0.93±0.09 vs. 0.66±0.03, all P < 0.05]. There was no significant difference in the parameters between DMSO group and CLP group.@*CONCLUSIONS@#Both GPX4 and FSP1 mediated ferroptosis are involved in liver injury in septic mice. Activation of ALDH2 and inhibition of ferroptosis can alleviatehepatic injury. ALDH2 may play a protective role by regulating FSP1 and GPX4 mediated ferroptosis.

ABSTRACT

Objective To explore the predictive value of the model for end-stage liver disease (MELD) score, energy metabolism and serum thyroid hormone levels on the severity and prognosis of patients with liver failure and their correlation. Methods This study collected clinicopathological data from 60 liver failure patients, e.g., end-stage liver disease (MELD) score, energy metabolism, and serum thyroid hormone levels. The χ 2 test was performed to analyze the categorical variables, while the Mann-Whitney U test and independent sample t test were performed to assess the continuous variables between the two groups. Spearman correlation coefficient test was used to evaluate correlation of each index. The receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off points of serum total triiodothyronine (TT3) and free triiodothyronine (FT3) levels in predicting prognosis of the patients. Results The rates of low TT3 and FT3 levels in liver failure patients were 78.2% and 69.1%, respectively, whereas the low TT3 rates were 95.2% and 67.6% and the low FT3 rates were 90.5% and 55.9% in survival and non-survival groups of patients, respectively (both P < 0.05). Moreover, the MELD score was significantly higher in the non-survival patients than in survival patients [26.0(21.0-29.0) vs 21.0 (19.0-24.0), Z =-3.396, P =0.001], while TT3 and FT3 levels were significantly lower in the non-survival patients than in the survival patients [0.69(0.62-0.73) vs 0.83(0.69-0.94) and 2.17(1.99-2.31) vs 2.54(2.12-2.86), respectively; Z =-2.884、-2.876, all P < 0.01]. The MELD score was negatively associated with serum TT3, FT3, and thyroid stimulating hormone (TSH) levels and the respiratory quotient (RQ) ( r =-0.487、-0.329、-0.422、-0.350, all P < 0.01), whereas the RQ was associated with serum TT3 and FT3 levels ( r =0.271、0.265, all P < 0.05). The optimal cutoff values in predicting the severity and survival of patients was 0.75 nmol/L and 2.37pmol/L with the sensitivity values of 67.6% and 64.7% and the specificity of 90.5% and 81.0%, respectively. Conclusion Abnormal thyroid hormone levels and low respiratory quotient could be used to predict the severity and prognosis of patients with liver failure.

ABSTRACT

Objective: To examine the efficacy and safety of laparoscopic surgery for gallbladder carcinoma. Methods: The data of 197 gallbladder carcinoma patients admitted at Peking Union Medical College Hospital between January 2012 and September 2022 were analyzed retrospectively. There were 86 males and 111 females,with age of (64.4±9.8)years(range:35 to 89 years). Patients were divided into laparoscopic group(n=53) and open group(n=144) according to different surgical methods. The general information of the two groups were matched by propensity score matching,and the clinical data and prognosis were compared between the two groups. Categorical variables were analyzed using χ2 test or Fisher's exact test,as appropriate. Continuous variables with and without normal distribution were analyzed using t-test and Mann-Whitney U test,respectively. Kaplan-Meier curves with Log-rank test were used to analyze the cumulative survival rates. Results: Forty-eight pairs of patients were matched successfully. There was no difference in general information,cholecystolithiasis,partial hepatectomy,and tumor stage between two groups(all P>0.05). The laparoscopic group had shorter operation time(t=-3.987,P<0.01),less bleeding(Z=-4.862,P<0.01),shorter total(Z=-5.009,P<0.01) and postoperative(Z=-5.412,P<0.01) hospital stay. Seventeen patients had postoperative complications. According to the Clavien-Dindo system,there were 4,11,1,and 1 patient with grade Ⅰ,Ⅱ,Ⅲa,and Ⅲb,respectively. All complications were improved after active treatment. After a median follow-up of 24(36) months(range:3 to 130 months),56 patients(58.3%) survived without tumor,7 patients(7.3%) survived with tumor,and 33 patients(34.4%) died. According to the Kaplan-Meier curves,there was no significant difference between laparoscopic and open groups in disease free(χ2=0.399,P=0.528) and overall(χ2=0.672,P=0.412) survival rates. Conclusions: The laparoscopic surgery is safe and effective in selected patients with gallbladder carcinoma. It can reduce surgical trauma and enhance patient recovery without increasing complication. Its prognosis is similar to that of open surgery.

ABSTRACT

Neoadjuvant chemotherapy has become an indispensable weapon against high-risk resectable cancers, which benefits from tumor downstaging. However, the utility of chemotherapeutics alone as a neoadjuvant agent is incapable of generating durable therapeutic benefits to prevent postsurgical tumor metastasis and recurrence. Herein, a tactical nanomissile (TALE), equipped with a guidance system (PD-L1 monoclonal antibody), ammunition (mitoxantrone, Mit), and projectile bodies (tertiary amines modified azobenzene derivatives), is designed as a neoadjuvant chemo-immunotherapy setting, which aims at targeting tumor cells, and fast-releasing Mit owing to the intracellular azoreductase, thereby inducing immunogenic tumor cells death, and forming an in situ tumor vaccine containing damage-associated molecular patterns and multiple tumor antigen epitopes to mobilize the immune system. The formed in situ tumor vaccine can recruit and activate antigen-presenting cells, and ultimately increase the infiltration of CD8+ T cells while reversing the immunosuppression microenvironment. Moreover, this approach provokes a robust systemic immune response and immunological memory, as evidenced by preventing 83.3% of mice from postsurgical metastasis or recurrence in the B16-F10 tumor mouse model. Collectively, our results highlight the potential of TALE as a neoadjuvant chemo-immunotherapy paradigm that can not only debulk tumors but generate a long-term immunosurveillance to maximize the durable benefits of neoadjuvant chemotherapy.

ABSTRACT

OBJECTIVES@#To investigate the effects and molecular mechanisms of asiatic acid on β-cell function in type 2 diabetes mellitus (T2DM).@*METHODS@#The T2DM model was established by high fat diet and streptozotocin injection in ICR mice, and the effects of asiatic acid on glucose regulation were investigated in model mice. The islets were isolated from palmitic acid-treated diabetic mice. ELISA was used to detect the glucose-stimulated insulin secretion, tumor necrosis factor (TNF)-α and interleukin (IL)-6. ATP assay was applied to measure ATP production, and Western blotting was used to detect protein expression of mature β cell marker urocortin (Ucn) 3 and mitofusin (Mfn) 2. The regulatory effects of asiatic acid on glucose-stimulated insulin secretion (GSIS) and Ucn3 expression were also investigated after siRNA interference with Mfn2 or treatment with TNF-α.@*RESULTS@#Asiatic acid with the dose of 25 mg·kg-1·d-1 had the best glycemic control in T2DM mice and improved the homeostasis model assessment β index. Asiatic acid increased the expression of Mfn2 and Ucn3 protein and improved the GSIS function of diabetic β cells in vitro and in vivo (both P<0.05). Moreover, it improved the ATP production of islets of T2DM mice in vitro (P<0.05). Interfering Mfn2 with siRNA blocked the up-regulation of Ucn3 and GSIS induced by asiatic acid. Asiatic acid inhibited islet TNF-α content and increased Mfn2 and Ucn3 protein expression inhibited by TNF-α.@*CONCLUSIONS@#Asiatic acid improves β cell insulin secretion function in T2DM mice by maintaining the β cell maturity, which may be related to the TNF-α/Mfn2 pathway.

ABSTRACT

In the case of periodontitis, local microecological imbalance can cause a large number of plaque biofilm accumulations, leading to the destruction of periodontal tissue and attachment loss, which makes it particularly difficult for the periodontal regenerative healing. In order to overcome the clinical treatment dilemma of periodontitis, periodontal tissue regeneration therapy assisted by new biomaterials has become a hot topic in recent years, among which electrospinning biomaterials with good biocompatibility have attracted wide attention. In this paper, based on periodontal clinical problems, the importance of functional regeneration is presented and clarified. Besides, according to the application of electrospinning biomaterials reported in previous researches, their effects of promoting functional periodontal tissue regeneration are analyzed. In addition, the internal mechanism of periodontal tissue repair by electrospinning materials is discussed and the future research direction is also proposed, in order to provide a new strategy for clinical treatment of periodontal diseases.

ABSTRACT

Furcation involvement (FI) is the lesion and destruction of periodontium that spread to the root furcation of multi-root teeth, where periodontal pockets, loss of periodontal attachment and resorption of alveolar bone are formed. Furcation involvement is a common concomitant lesion of periodontitis. The severity of furcation involvement can directly affect the prognosis of periodontitis. However, the specificity of the anatomical structure of the root furcation greatly increases the difficulty of treatment. Therefore, early detection and treatment of furcation involvement is crucial for the prevention and control of periodontitis.

ABSTRACT

ObjectiveTo investigate the effect of xenon post-conditioning on autophagy after spinal cord ischemia/reperfusion injury (SCIRI) in rats and its relationship with protein kinase B (Akt) signaling pathway. MethodsA total of 30 male rats were randomized into sham-operated group (sham group), spinal cord ischemia/reperfusion injury group (I/R group) and I/R + xenon post-conditioning group (Xe group), with ten rats in each group. In the latter two groups, SCIRI was induced by clamping the abdominal aorta for 85 minutes followed by reperfusion for four hours. Xe group inhaled xenon and oxygen (1∶1) for one hour at one hour after initiation of reperfusion, while the other groups inhaled nitrogen and oxygen (1∶1) for one hour. After the reperfusion, they were assessed with Basso-Beattie-Bresnahan (BBB) scale and slanting board test. And then, their spinal cords of L3-5 were obtained. Nissl staining was used to count the number of normal neurons. Western blotting was used to detect the protein expression of Akt, p-Akt, p62, Beclin 1, microtubule-associated protein 1 light chain 3 (LC3) Ⅰ, LC3 Ⅱ. The mRNA expression of Beclin 1, p62 and LC3 Ⅱ in the spinal cord was measured with reverse transcription real-time quantitative polymerase chain reaction. ResultsCompared with the sham group, the BBB score and the maximum inclination of the slanting board test decreased, the count of normal neurons decreased, the protein expression of p62 and the p-Akt/Akt ratio decreased (P < 0.01), the protein and mRNA expression of Beclin 1 and LC3 Ⅱ, and the LC3 Ⅱ/LC3 Ⅰ ratio increased, the p62 mRNA expression decreased (P < 0.01) in the I/R group. Compared with the I/R group, the BBB score and the maximum inclination of the slanting board test increased, the count of normal neurons increased, the protein expression of p-Akt and p62 increased, the p-Akt/Akt ratio increased, the protein and mRNA expression of Beclin 1, LC3 Ⅱ and LC3 Ⅱ/LC3 Ⅰ ratio decreased, and the mRNA expression of p62 increased (P < 0.01) in Xe group. ConclusionXenon post-conditioning may relieve SCIRI in rats, which is related to activating Akt signaling pathway to inhibit autophagy.

ABSTRACT

Objective@#To explore the relationship between maternal emotional symptoms and emotional and behavioral problems (EBPs) of preschool offspring, and to provide reference for prevention and intervention of emotional and behavior problems in preschool children.@*Methods@#A total of 4 100 preschool children aged 3-6 in Fuyang City were enrolled by stratified cluster sampling method in June 2021. The Strengths and Difficulties Questionnaire (SDQ) and Depression Anxiety and Stress Scale (DASS-21) were used to investigate preschool children s EBPs and maternal emotional symptoms, respectively.@*Results@#The detection rates of preschool children s emotional symptoms, conduct problems, hyperactivity, peer interaction problems, prosocial behavior and difficulty scores were 15.7%, 17.4%, 20.0%, 32.3%, 15.1% and 15.8%, respectively. The detection rates of mother s depression, anxiety and stress symptoms were 7.9%, 12.7% and 4.8%, respectively. Multivariate Logistic regression analysis showed that, compared with children of mothers with no depression, anxiety and stress symptoms, offspring of mothers reported depression, anxiety and stress symptoms had significantly higher risks of emotional symptoms, conduct problems, hyperactivity, peer problems and total difficulties ( OR=1.76-6.35, P <0.01). Maternal emotional symptoms had the most significant effect on children s emotional symptoms, and there was no significant correlation between maternal stress symptoms and children s prosocial behavior ( OR=1.40, P >0.05). There was no significant gender difference in the relationship between maternal emotional symptoms and children s emotional and behavioral problems ( ROR=0.73-1.07, P >0.05). For only children whose mothers reported stress symptoms showed a higher risk of emotional and behavior problems than non singleton children ( ROR=2.03, P <0.05).@*Conclusion@#Maternal emotional symptoms are related to preschool children s emotional and behavioral problems. Early identification and intervention of mother s negative emotional symptoms, are beneficial to the prevention of preschool children s emotional and behavioral problems.

ABSTRACT

Objective:To analyze the effect of the implementation of diagnosis-intervention packet (DIP) on the doctors′ diagnosis and treatment behavior of chronic diseases, so as to provide reference for further improving medical insurance payment related policies.Methods:The first page information of chronic disease patients admitted to hospitals with diabetes, hypertension and coronary atherosclerotic heart disease as the main conditions in 103 hospitals at all levels and township health centers in a city from 2016 to 2020 was collected, and the patients were divided into non-DIP group and DIP group according to the implementation time of DIP. After 1∶1 propensity score matching to balance the general conditions of the 2 groups, the diagnosis and treatment behaviors were analyzed from two dimensions: diagnostic behavior and treatment behavior. The grade A rate of medical record writing, admission and discharge diagnosis coincidence rate, and the average length of stay were used to evaluate the diagnostic behavior; the proportion of drugs and the degree of change in the cost structure were used as the evaluation indicators of treatment behavior.Results:After matching, 41 050 patients were included in both the non-DIP group and the DIP group.From the perspective of diagnostic behavior, the grade A rate of medical record writing in the non-DIP group and the DIP group was 99.40% and 99.83%, the coincidence rate of admission and discharge diagnosis was 58.42% and 61.79%, the average hospital stay was 8.03 days and 7.04 days respectively, and the difference between the groups was significant ( P<0.05). From the view of treatment behavior, the proportion of drugs decreased from 33.00% in the non-DIP group to 27.59% in the DIP group, with a significant difference ( P<0.05); the drug cost represented by Western medicine changed negatively, while the diagnostic cost showed a positive change. Conclusions:DIP has played a certain role in regulating doctors′ diagnosis and treatment behavior for chronic diseases. Among them, doctors have significantly improved their diagnostic behavior for chronic diseases, and the proportion of drugs in treatment behavior has been well controlled.

ABSTRACT

Objective:To evaluate the role of bilateral superior cervical sympathetic ganglia (SCG) in myocardial ischemia-reperfusion (I/R) injury in mice and the relationship with NOD-like receptor protein 3 (NLRP3) inflammasomes.Methods:Thirty-two healthy SPF male C57BL mice, aged 8-10 weeks, weighing 25-30 g, were divided into 4 groups ( n=8 each) by the random number table method: sham operation group (NS group), myocardial I/R group (NIR group), bilateral SCG excision group (SCGx group) and bilateral SCG excision + myocardial I/R group (SCGx+ IR group). The myocardial I/R injury model was prepared by ligating the anterior descending branch of the left coronary artery for 30 min followed by 24 h reperfusion in isoflurane-anesthetized mice. Bilateral superior cervical sympathectomy was performed at 3 days before reperfusion. Blood samples were collected from the inferior vena cava at 24 h of reperfusion for examination of pathological changes (by HE and WGA staining) and for measurement of serum creatine kinase isoenzymes (CK-MB) activity, cardiac troponin I (cTnI) concentration, norepinephrine (NE) concentration and lactic dehydrogenase (LDH) activity (by enzyme-linked immunosorbent assay), superoxide dismutase (SOD) activity (by colorimetric method), myocardial reactive oxygen species (ROS) level (by DHE method), myocardial infarct size(by TTC method), and expression of interleukin-1beta (IL-1β), IL-6, IL-10, tumor necrosis factor-alpha (TNF-α), NLRP3 mRNA (by quantitativepolymerase chain reaction ), and expression of tyrosine hydroxylase (TH), IL-1β, TNF-α, NLRP3, atrial natriuretic peptide (ANP)and brain natriuretic peptide (BNP) (by Western blot). Results:Compared with NS group, the NE concentration was significantly decreased, and TH expression was down-regulated in SCGx group, and the serum CK-MB activity, concentrations of cTnI and NE, LDH activity and myocardial ROS level were significantly increased, SOD activity was decreased, the expression of IL-1β, TNF-α, NLRP3, ANP and BNP was up-regulated, and the expression of IL-1β, IL-6, TNF-α and NLPR3 mRNA was up-regulated in NIR group ( P<0.05). Compared with SCGx group, the serum CK-MB activity, concentrations of cTnI and NE, LDH activity and myocardial ROS levels were significamtly increased, SOD activity was decreased, the expression of IL-1β, TNF-α, NLRP3, ANP and BNP was up-regulated, and the expression of IL-1β, IL-6, TNF-α and NLPR3 mRNA was up-regulated in SCGx+ NIR group ( P<0.05). Compared with NIR group, the serum CK-MB activity, cTnI concentration, LDH activity and myocardial ROS level were significantly decreased, SOD activity was increased, the expression of IL-1β, TNF-α, NLRP3, ANP and BNP was down-regulated, the expression of IL-1β, IL-6, TNF-α and NLPR3 mRNA was down-regulated, and myocardial infarct size was decreased in SCGx+ NIR group ( P<0.05). Conclusions:The mechanism by which bilateral SCG excision attenuates myocardial I/R injury is associated with decreased NLRP3 inflammatory inflammasome activation and inhibition of inflammatory responses in mice.

ABSTRACT

Objective:To evaluate the effects of remazolam and propofol on the hemodynamics during induction of anaesthesia in elderly patients using the area under curve (AUC) method.Methods:Eighty elderly patients of either sex, aged 65-75 yr, with body mass index of 20-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective non-cardiac surgery, were divided into 2 groups ( n=40 each) by using a random number table method: remazolam group (R group) and propofol group (P group). Remazolam 1 mg/ml or propofol 10 mg/ml was slowly and intravenously injected through titration to achieve loss of responsiveness to verbal command. The accumulative areas under the curve below (AUC MAP-) or above (AUC MAP+ ) baseline mean arterial pressure and under the curve below or above 10% of baseline heart rate at the same time (AUC HR-, AUC HR+ ) were calculated within the first 10 min after administration of propofol or remazolam. The use of vasoactive drugs and injection pain were recorded during this period. The intraoperative awareness during the 24-h follow-up after surgery and development of cardiovascular complications, cerebral infarction and oliguria or anuria within 30 days after surgery were recorded. Results:Compared with R group, AUC MAP- was significantly enlarged (the mean difference 59.375 mmHg·min, 95% confidence interval 26.763-91.987 mmHg·min), AUC HR- was enlarged ( P<0.05), and no significant change was found in AUC MAP+, AUC HR+, requirement for vasoactive drugs, frequency of vasoactive drugs, and postoperative complications in P group ( P>0.05). No injection pain or intraoperative awareness was found in two groups. Conclusions:Remazolam is superior to propofol in maintaining hemodynamic stability during anesthesia induction in elderly patients.
