Objective:To analyze the effects of electrophysiological combined therapy on pelvic floor function and electrophysiological indexes of pelvic floor in elderly patients with pelvic prolapse.Methods:A total of 46 elderly patients with pelvic prolapse admitted to Noncommissioned Officer School Hospital, Army Medical University from Jan. 2022 to Jul. 2023 were selected as subjects. All patients were divided into control group and study group by random number table method, with 23 cases in each group. The control group was treated with conventional operation, and the study group was treated with electrophysiological combination. The therapeutic effect, psychological state, pelvic floor electrophysiology and pelvic floor muscle function before and after treatment were compared between the two groups.Results:The treatment efficacy rate in the observation group was 95.65%, while that in the control group was 73.91%, with the observation group showing a significantly higher rate than the control group ( P<0.05). There were no statistically significant differences between the two groups in terms of psychological state scores, pelvic floor electrophysiological indicators, or pelvic floor muscle function before treatment ( P>0.05). After treatment, the SAS score, SDS score, fatigue degree of Type I muscle fibers, fatigue degree of Type II muscle fibers, and absolute values of gh scores in the observation group were lower than those in the control group ( P<0.05) ; The observation group had higher Type I muscle fiber strength, Type II muscle fiber strength, Ba point, Bp point, pb point, TVL point, pelvic floor contraction pressure, rapid contraction pressure, resting pressure, and number of contractions than the control group ( P<0.05) . Conclusion:Electrophysiological combined therapy is helpful to improve the therapeutic effect of elderly patients with pelvic prolapse, improve their psychological state, pelvic floor electrophysiological indexes and pelvic floor muscle function.

Objective:To investigate the diagnostic value of nucleic acid matrix-assisted laser desorption ionization-time of flight mass spectrometry（MALDI-TOF MS）in sputum smear-negative patients with nontuberculous Mycobacterial（NTM）pulmonary disease.Methods:Clinical data of 123 patients suspected of NTM pulmonary disease admitted in Public Health Clinical Center Affiliated to Shandong University between July 2022 and November 2023 were retrospectively analyzed. Bronchoalveolar lavage fluid（BALF）specimens were collected for MALDI-TOF MS assay and MGIT 960 culture. The diagnostic efficacy of MALDI-TOF MS for NTM pulmonary disease in patients with negative sputum smears for acid-fast bacilli was evaluated with receiver operating characteristic（ROC）curve. Statistical analysis was performed using SPSS 26.0 software and MedCalc statistical software.Results:Diagnosis of NTM pulmonary disease was finally confirmed in 66 out of the 123 suspected patients. It took 8 to 24 h for MALDI-TOF MS to identify NTM species and resistance. By MALDI-TOF MS，72 NTM strains were identified，with the Mycobacterium avium complex being the most prevalent（34 strains，47.22%），followed by the Mycobacterium abscessus complex（13 strains，18.06%）；resistance to macrolides was detected in 6 cases，while no resistance to aminoglycosides was found. It took 9 to 45 days for BALF MGIT 960 culture to identify NTM，and took 7 to 15 days for NTM typing and drug sensitivity testing. By BALF MGIT 960 culture，28 NTM strains were identified；and 1 case was found to be resistant to macrolides. Using confirmed diagnosis as the gold standard，MALDI-TOF MS demonstrated higher sensitivity，negative predictive value，and agreement rate compared to MGIT 960 culture（84.85% vs. 42.42%，81.13% vs. 56.32%，80.49% vs. 62.60%， χ2=25.667，8.998，9.664， P<0.05 or <0.01）. The area under ROC curve（AUC）for MALDI-TOF MS was significantly higher than that of MGIT 960 culture（0.801 vs. 0.642， Z=3.300， P=0.001）. Conclusion:Compared to MGIT 960 culture，MALDI-TOF MS exhibits superior diagnostic efficiency in detecting NTM pulmonary disease in patients with acid-fast bacilli smear-negative sputum，with advantage of rapidly identifying NTM species and resistance.

Objective To compare the effects of ginsenosides Rg1 and Rb1 on depression-and anxiety-like behaviors in chronic unpredictable stress-induced rats.Methods Seventy male SPF grade SD rats were tested for sugar and water preference after 5 days of adaptation and divided into seven groups according to their preference index:a control group,model group,fluoxetine hydrochloride group,ginsenoside Rg1 24 mg/kg group,ginsenoside Rg1 48 mg/kg group,ginsenoside Rb1 33 mg/kg group,and ginsenoside Rb1 67 mg/kg group.All rats,except for the control group,were subjected randomly to one or two different stimulating factors every day for a total of 35 days.On the 36th day,behavioral experiments including sugar and water preference,open field,novel environment feeding inhibition,elevated cross maze,and forced swimming experiments were conducted to investigate the anti-depression and anti-anxiety effects of the treatments.Serum and hippocampal levels of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-α and serum corticosterone were measured by enzyme-linked immunosorbent assay.Results Compared with the model group,ginsenoside Rg1 and Rb1 significantly increased sucrose consumption in the sucrose preference test and decreased immobility in the forced swimming test.Ginsenoside Rg1(48 mg/kg)significantly reduced the latency to eat in the novelty-suppressed feeding test,and ginsenoside Rg1(24 and 48 mg/kg)significantly increased the percentage of open arm entries and time in the elevated cross maze test.Serum corticosterone levels were significantly decreased in the ginsenoside Rg1 and Rb1 groups,serum IL-1β and IL-6 levels were significantly decreased in the ginsenoside Rg1(48 mg/kg)group,serum TNF-α and IL-6 levels were significantly decreased in the ginsenoside Rb1(33 mg/kg)group,and IL-1β,IL-6,and TNF-α levels in the hippocampus were significantly decreased in the ginsenoside Rg1(48 mg/kg)and Rb1(67 mg/kg)groups.Conclusions Both ginsenosides can regulate the hypothalamic-pituitary-adrenal axis and inhibit neuroinflammation,improving depression-and anxiety-like behaviors in rats induced by chronic unpredictable stress.Ginsenoside Rg1 has a significantly better anti-anxiety effect than Rb1.

Objective:To explore the association between child abuse and suicidal ideation in patients with bi-polar disorder.The mediation of self-esteem and depression in this association was also investigated.Methods:A to-tal of 292 patients with bipolar disorder who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were enrolled.Their child abuse,suicidal ideation,self-esteem,depres-sion,and mania were assessed with the Childhood Trauma Questionnaire(CTQ),Beck Scale for Suicide Ideation-Chinese Version(BSICV),Self-Esteem Scale(SES),17-item Hamilton Depression Rating Scale(HAMD-17)and Young Mania Rating Scale(YMRS).The mediating effects were evaluated using PROCESS for SPSS.Results:The BSICV scores were positively associated with the scores of CTQ(r=0.37,P＜0.01)and HAMD-17(r=0.53,P＜0.01)and negatively associated with SES scores(r=-0.50,P＜0.01)in patients with bipolar disorder.Self-esteem and depression played mediating roles between child abuse and suicidal ideation,respectively(95％CI:0.01-0.09,0.01-0.10).Besides,self-esteem and depression sequentially mediated the relationship between child a-buse and suicidal ideation(95％CI:0.02-0.06).Conclusion:Child abuse,low self-esteem,and depression may be related factors of suicidal ideation in patients with bipolar disorder.

Objective: Autism spectrum disorder (ASD) is a neurodevelopmental disorder with onset in infancy. Early intervention is critical to improve the prognosis for these children. E-health interventions have tremendous potential. This review aimed to determine the status and effectiveness of family interventions for parents of children aged 0–6 years with ASD in the context of e-health. Methods: The review methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. PubMed, Web of Science, and China National Knowledge Infrastructure were searched from inception to June 2022. The searches were limited to children with ASD of the age range between 0 and 6 years. We collated the available information and used descriptive statistics to analyze the synthesized data. Results: Our initial search identified 3,672 articles, of which 30 studies met the inclusion criteria. The 30 articles selected were released between 2012 and 2022. All articles are in English. Most articles reviewed were from high-income countries (27/30, 90.0%), especially from the United States (16/30, 53.3%). Four major themes emerged from the 30 studies that matched the inclusion criteria, as follows: 1) type of e-health interventions, 2) duration of interventions, 3) clinical aspects of e-health interventions, and 4) evidence for intervention effectiveness, looking into the positive, negative, and mixed findings of previous studies. Conclusion These findings suggest that a wide variety of e-health interventions may actually help support both children with ASD aged 0–6 years and their parents.

To conduct the association between vitamin B12 and mental health in children and adolescents. Five databases were searched for observational studies in any language reporting on mental health and vitamin B12 levels or intake in children and adolescents from inception to March 18, 2022. Two authors independently extracted data and assessed study quality. Qualitative and quantitative analysis of data were performed. The review was registered in the PROSPERO database (CRD42022345476). Fifty six studies containing 37,932 participants were identified in the review. Vitamin B12 levels were lower in participants with autism spectrum disorders (ASD) (standardized mean difference [SMD], −1.61;95% confidence interval [95% CI], −2.44 to −0.79; p ＜ 0.001), attention deficit hyperactivity disorders (SMD, −0.39; 95% CI, −0.78 to −0.00; p = 0.049) compared with control group. Vitamin B12 intake were lower in participants with ASDs (SMD, −0.86; 95% CI, −1.48 to −0.24; p = 0.006) compared with control group, but showed no difference between depression group (SMD, −0.06; 95% CI, −0.15 to 0.03; p = 0.17) and the control group. Higher vitamin B12 intake were associated with lower risk of depression (odds ratio [OR], 0.79; 95% CI, 0.63−0.98; p = 0.034) and behavioral problems (OR, 0.83; 95% CI, 0.69−0.99; p = 0.04). The vast majority of included studies supported potential positive influence of vitamin B12 on mental health, and vitamin B12 deficiency may be a reversible cause for some mental health disorders in children and adolescents.

ObjectiveTo explore the effects of negative life events on suicidal ideation in adolescents with depressive disorder and the mediating role of mother-child attachment， so as to provide references for reducing suicidal ideation in adolescents with depression. MethodsA total of 145 adolescents underwent psychiatric inpatient and outpatient treatment in the First Affiliated Hospital of Chongqing Medical University From May 2020 to April 2021 and met the International Classification of Diseases， tenth edition （ICD-10） criteria for depressive episode were enrolled， and all selected individuals were assessed using the Adolescent Self-rating Life Events Checklist （ASLEC）， the Inventory of Parent and Peer Attachment （IPPA） and Beck Scale for Suicide Ideation-Chinese Version （BSI-CV）. Then Bootstrap method was used to test the mediating effect. ResultsBSI-CV score in adolescents with depressive disorder was positively correlated with ASLEC score （r=0.453， P<0.01）， and negatively correlated with mother-child attachment score in IPPA （r=-0.165， P<0.01）. The partial mediating effect of mother-child attachment between negative life events and suicidal ideation was significant， with a mediating effect value of 0.008， accounting for 14.55% of the total effect value （0.055）. ConclusionSuicidal ideation in adolescents with depressive disorder may be related to loads of negative life events and poor mother-child attachment， moreover， mother-child attachment plays a mediating role in the relationship between negative life events and suicidal ideation.

Objective:To explore the relationship between endocannabinoid (eCB) and its metabolic enzymes and severity of autism spectrum disorder (ASD), and to provide a theoretical basis for the study of the etiology and pathogenesis of ASD.Methods:A case-control study was conducted to collect 58 ASD children who underwent rehabilitation training at the Children's Developmental Behavior Research Center of Harbin Medical University and the provincial autism rehabilitation facility from December 2017 to December 2018 as the ASD group.According to the principle of gender and age 1∶1 matching, 58 normal children were selected as control group in Heilongjiang Province.Liquid chromatography-tandem mass spectrometry (LC-MS/MS) and real-time quantitative PCR (RT-qPCR) were used to detect eCB of ASD group and control group, including anandamide (AEA), 2-arachidonoylglycerol (2-AG), palmitoylethanolamide (PEA), oleoylethanolamide (OEA) and its metabolic enzymes: n-acylphosphatidylethanolamine-specific phospholipase D (NAPE-PLD), fatty acid amide hydrolase (FAAH), monoacylglycerol lipase (MAGL) and diacylglycerol lipase (DAGL) mRNA expression levels.Pearson correlation was used to analyze the level of eCB and ASD children's severity.Results:The levels of AEA, OEA and PEA in ASD children ((10.10±2.6)nmol/L, (24.30±5.60)nmol/L, (15.92±2.28)nmol/L) were lower than those in the control group ((13.46±3.04)nmol/L, (27.85± 6.89)nmol/L, (17.87±2.67)nmol/L, t=-6.612, -3.99, -4.779, P<0.01). The expression levels of FAAH and DAGL mRNA in ASD children were significantly higher than those in the control group, and the difference was statistically significant( t=2.423, 3.840, P<0.05), while NAPE-PLD and MAGL mRNA levels were not significantly different between the two groups ( t=0.024, 0.885, P>0.05). The level of PEA in the ASD group was negatively correlated with the total score of the autism behavior checklist (ABC) ( r=-0.288, P<0.05). Conclusion:There may be metabolic abnormalities in eCB and its metabolic enzymes in ASD children, and the level of eCB is related with the severity of ASD.

Objective:To evaluate the value of lung ultrasound score (LUS) on predicting weaning outcome in patients with intro-abdominal infection (IAI) undergoing mechanical ventilation.Methods:Patients with IAI undergoing mechanical ventilation admitted to Research Institute of General Surgery of East War Zone Hospital and intensive care unit (ICU) of the First People's Hospital of Lianyungang from January to December in 2018 were included. The patients who satisfied weaning criteria were enrolled in the weaning process, which included spontaneous breathing trial (SBT) and extubation. They were divided into SBT success group and SBT failure group according to whether passed 120-minute SBT or not. LUS scores before and after SBT were compared between the two groups. The patients in the SBT success group were extubated, and they were divided into successful extubation group and failed extubation group for sub-group analysis according to whether re-intubation was needed in 48 hours after extubation. LUS score before extubation (at the end of SBT) and 48 hours after extubation (48 hours after extubation in the successful extubation group or before re-intubation in the failed extubation group) were compared. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of LUS score before SBT for SBT failure and LUS score before extubation for the failure.Results:A total of 76 patients with IAI undergoing mechanical ventilation were included. Twenty-three patients had duration of mechanical ventilation less than 48 hours, severe chronic obstructive pulmonary disease (COPD), tracheotomy or automatic discharge were excluded, and 53 patients were enrolled. SBT was failed in 9 patients, and successfully performed in 44 patients, of whom 23 patients with successful extubation, and 21 with failed extubation. The LUS scores before and after SBT in the SBT failure group were significantly higher than those in the SBT success group (before SBT: 13.22±1.99 vs. 10.79±1.64, t = -3.911, P = 0.000; after SBT: 19.00±1.12 vs. 13.41±1.86, t = -8.665, P = 0.000). ROC curve analysis showed that the area under ROC curve (AUC) of LUS score before SBT for predicting SBT failure was 0.82 [95% confidence interval (95% CI) was 0.67-0.98, P = 0.002]. When the optimum cut-off value was 12.5, the sensitivity was 66.7%, and the specificity was 84.1%. Sub-group analysis showed that the LUS scores before and after extubation in the failed extubation group were significantly higher than those in the successful extubation group (before extubation: 14.19±1.60 vs. 12.69±1.81, t = -2.881, P = 0.006; after extubation: 16.42±1.59 vs. 12.78±1.54, t = -7.710, P = 0.000). ROC curve analysis showed that the AUC of LUS score before extubation for predicting the failure was 0.81 (95% CI was 0.69-0.92, P = 0.000). When the optimum cut-off value was 13.5, the sensitivity was 80.0%, and the specificity was 65.2%. Conclusion:LUS score can effectively predict SBT outcome, risk of re-intubation after extubation in patients with IAI undergoing mechanical ventilation.
