Objective To calculate median effective dose(ED50)of remimazolam combined with sufentanil for inhibition of nasopharyngeal airway insertion reaction in elderly patients.Methods Thirty-eight patients,aged≥65 years,BMI 18-25 kg/m2,ASA physical statusⅠ-Ⅲ,undergoing elective cata-ract surgery under nasopharyngeal airway were selected.Patients received intravenous sufentanil injections of 0.1 μg/kg,followed by intravenous remimazolam injection 3 minutes later,then nasopharyngeal airway in-sertion after 2 minutes.The initial dose of remimazolam was 0.2 mg/kg and adjusted by 0.01 mg/kg,based on the modified Dixon sequential method.A positive reaction was defined as head shaking,choking,body movement,an increase in HR＞20%of the basal value,or an increase in SBP or DBP＞20%of the basal value at the time of nasopharyngeal airway placement.The procedure was stopped after seven crossovers.The ED50,95%effective dose(ED95)of remimazolam,and 95%confidence intervals(CI)were calculated by probabilistic unit(Probit)regression analysis.Results When combined with sufentanil,the ED50 and ED95 of remimazolam for inhibition of nasopharyngeal airway insertion in elderly patients was 0.193 mg/kg(95%CI 0.191-0.195 mg/kg)and 0.209 mg/kg(95%CI 0.205-0.213 mg/kg),respectively.Conclusion The ED50 of remimazolam combined with sufentanil for inhibition of nasopharyngeal airway in-sertion reaction in elderly patients were 0.193 mg/kg(95%CI 0.191-0.195 mg/kg).

Objective To systematically analyze influencing factors of migration stress of patients'families transferred out of intensive care unit(ICU)in China,and provide evidence-based guidance for alleviating migration stress level of families of transferred patients.Methods Computer searches were conducted on China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP,China Biomedical Literature Database,Web of Science,PubMed,the Cochrane Library and Embase for observational studies such as cohort studies,case-control studies and cross-sectional studies on factors influencing migration stress among family members of ICU patients.Search deadline was from database establishment to October 2023.Literature screening,quality assessment and data extraction were conducted independently by two researchers in accordance with the inclusion and exclusion criteria.RevMan5.4 software was used to conduct a Meta-analysis of the data results.Results Fifteen studies were finally included,with a total sample size of 2558 and 12 influencing factors were extracted.Fifteen articles were divided into positive scoring group(higher scores,higher levels of migration stress,nine articles)and negative scoring group(higher scores,lower levels of migration stress,six articles)based on instruments used to measure outcome indicators.When analyzing each group,only factors mentioned in the group more than twice were included in Meta analysis.Meta analysis showed that within positive scoring group,family member education level,family member gender,patient awareness,ICU treatment time and family member uncertainty about the disease were factors affecting migration stress of ICU transfer patients'families(P<0.05);In reverse calculation group,educational level of family member,gender of family member,age of patient and ICU treatment time were influencing factors of migration stress of family members of ICU transfer patients(P<0.05).Sensitivity analysis result showed that result of each factor was relatively stable.Conclusion Educational level of family member,gender of family member,age of patient,ICU treatment time,uncertainty of family member's illness are influencing factors of migration stress of family members of patients transferred out of ICU in China.Influence of family member's religious beliefs and patient's consciousness needs further demonstration.

Neuropathic pain is a clinical symptom with complex mechanisms and high incidence. The commonly used analgesics have limited efficacy and can cause serious side effects. The theory of chronic pain entering collaterals was proposed by YE Tianshi， a famous physician focusing on warm diseases in the Qing dynasty， on the basis of the ancient therapies for pain. This theory is particularly suitable for the diagnosis and treatment of neuropathic pain in view of the clinical course and manifestations. The chronic neuropathic pain can enter the Yin collateral in deeper sites. The pathogenesis of neuropathic pain is summarized as a deficiency in origin and excess in superficiality. The root cause is the dysfunction of Zang-Fu organs， mainly the liver, kidney and heart， while the superficial causes are phlegm and stasis caused by the obstructed Qi and blood movement due to the consumption of Qi and blood in collaterals. Accordingly， the therapies such as dispelling blood stasis， resolving phlegm， and dredging collaterals should be adopted. This paper expounds the traditional Chinese medicine （TCM） pathogenesis and treatment of neuropathic pain， enriching the knowledge and providing new ideas for the TCM prevention and treatment of this disease as a collateral disease.

Objective:To explore the difference of theory of mind between adolescent depressive disorder patients with and without suicide attempt and its correlation with depression severity.Methods:From September 2019 to April 2021, totally 56 cases of attempted suicide adolescent depression patients(suicide attempted group), and 78 non-attempted suicide adolescent depression patients (non-suicide attempted group) and 23 healthy controls (healthy control group) with matched sex, age and years of education were included.The 17-item Hamilton depression scale(HAMD-17) and mini-international neuropsychiatric interview (M. I. N. I. ) were evaluated in all the subjects for depression severity and suicide trait related clinical psychological scale, theory of mind-picture sequencing task (ToM-PST) includes primary belief, primary false belief, secondary belief, secondary false belief, third-level false belief, sense of reality, reciprocity, deception and deception detection, which were used to test the theory of mind of the three groups. SPSS 25.0 software was used to statistically analyze the data, compare the differences of ToM of the three groups, and Pearson correlation analysis was used to analyze the correlation between ToM of the attempted suicide group and the clinical behavior scale.Results:The suicide attempted group was significantly lower in understanding primary false belief ((2.46±0.63) vs (2.87±0.46)) than the healthy control group( P<0.05), and the understanding of deception((2.84±0.42) vs (2.63±0.61)) was significantly higher than the non-suicide attempted group( P<0.05), and the non-suicide attempted group was significantly lower in understanding primary false belief((2.48±0.72) vs ( 2.87±0.46)) and ToM total scores((50.86±6.60) vs (54.91±5.12)) than the healthy control group(both P<0.05). Pearson correlation analysis showed that the secondary false belief of the attempted suicide group were negatively correlated with the cognitive impairment( r=-0.267, P<0.05), and third-level false belief was negatively correlated with the cognitive impairment, retardation, and depressiontotal score( r=-0.331, r=-0.319, r=-0.269, all P<0.05). There was no significant correlation between primary belief, primary false belief, secondary belief, sense of reality, reciprocity, deception, deception detection, total score of picture ranking, total score of ToM and depression in suicide attempt group(all P>0.05). Conclusion:The ability to understand deception is different between depression adolescents with and without suicide attempt, and it is not correlated with the severity of depression.

Objective:To explore the difference of brain structure between patients with early-onset depression with and without suicidal ideation and its relationship with the severity of depression.Methods:Totally 37 patients with early-onset depressive disorder with suicidal ideation and 23 patients with early-onset depressive disorder without suicidal ideation were examined by psychological assessment and magnetic resonance imaging(MRI)from 2019 to 2020.Voxel-based morphometry (VBM) technology was used to compare the differences in brain structure between the two groups of subjects, and further analyze the relationship between the gray matter volume of the different brain areas and the severity of depression. The demographic and clinical data were analyzed by SPSS 24.0 statistical software package. The comparison between the two groups was performed by double sample t-test and chi square test. SPM8 software was used for VBM statistical analysis, and double sample t test was used for image analysis and comparison between the two groups. Pearson correlation analysis was performed between the mean gray matter volume of the two groups and the scores of HAMD-17 and Beck scale for suicide ideation(BSI). Results:Compared with the group without suicide ideation, the volume of gray matter in the right middle frontal gyrus(MNI: x, y, z=28.5, 33.0, 43.5, FWE correction for mass level, P<0.05)and left angular gyrus of the suicide idea group increased(MNI: x, y, z=-37.5, -73.5, 48.0, FWE correction for mass level, P<0.05). There was no significant correlation between the gray matter volume of the right middle frontal gyrus and the HAMD-17 scale, BSI scale in patients with early-onset depression ( r=0.073, r=-0.153, both P>0.05). Conclusion:There are structural differences in the right middle frontal gyrus and left angular gyrus between patients with early-onset depression with suicidal ideation and patients with early-onset depression without suicidal ideation, and there was no significant correlation between gray matter volume and depression severity.

Portal vein thrombosis (PVT) is one of the most common complications of liver cirrhosis. Due to coagulation disorder and the risk of bleeding in liver cirrhosis, there are many controversies over the treatment of liver cirrhosis with PVT in clinical practice. Common therapies for PVT include anticoagulant therapy, intervention, and thrombolysis. This article elaborates on the current status of the treatment of liver cirrhosis with PVT, in order to provide help for the development of standard and reasonable clinical treatment strategies.

ObjectiveTo analyze the coping style and its relationship with anxiety status among middle school students aged 13 to 18 in Anhui province during the COVID-19 epidemic. MethodsFrom February 13 to 19， 2020， a cross-sectional survey was conducted among middle school students in Anhui province by using convenience sampling method and network questionnaire. The assessment tools included the Coping Style Scale for Middle School Students （CSSMSS） and the Screen for Child Anxiety Related Emotional Disorders （SCARED）. ResultsThe results of the CSSMSS evaluation showed that female students scored higher in emotion abreaction than male students ［（8.27±2.98） vs. （7.84±2.91）］. The scores of tolerance ［（9.74±2.73） vs. （9.11±2.60）］， escape ［（7.82±2.79） vs. （7.26±2.44）］， emotion abreaction ［（8.48±2.97） vs. （7.91±2.93）］ and fantasy/denial ［（9.79±3.56） vs. （9.26±3.47）］ of senior high school students were higher than those of junior high school students， and the score of problem solving ［（19.38±4.07） vs. （20.33±4.54）］ was lower than that of junior high school students， with statistical significance （P<0.05 or 0.01）. Correlation analysis results showed that the scores of tolerance， escape， emotion abreaction and fantasy/deny in CSSMSS were positively correlated with the scores of SCARED of middle school students in Anhui province （r=0.348， 0.287， 0.390， 0.501， P<0.01）.

Objective:To compare the safety of continuous suture and interrupted suture in Laparoscopic Sleeve Gastrectomy and Omentopexy.Methods:The retrospective study include 121 patients who underwent Laparoscopic Sleeve Gastrectomy and Omentopexy in the Department of Obesity and Metabolic Surgery of the First Affiliated Hospital of Jinan University from January 2019 to March 2020.Among the 121 patients, 40 were males and 81 females, with an average age of (30.17±10.16) and (27.10±11.03), respectively. Among them, 70 patients used continuous suture during OP (continuous suture group), and 51 patients used intermittent suture (interrupted suture group). The operation time, intraoperative blood loss, postoperative pain score, postoperative complications were compared between the two groups. Normally distributed measurement data were measured as (mean ± standard) deviation ( Mean± SD), and t test was used to count the comparison between the two groups. The χ2 test was used to compare the measurement data between groups. The rank data used Wilconxon rank sum test. Results:(1) Intraoperative conditions: the operative time and intraoperative blood loss in the continuous suture group were (124.89±37.69) min and (7.3±2.5) mL, respectively. In the interrupted suture group, the above indexes were (124.80±35.53) min and (7.0±2.5) mL, respectively. There was no significant difference between the two groups ( t=0.012, 0.709, P>0.05). (2) Postoperative conditions: postoperative pain score and postoperative hospital stay in the continuous suture group were: mild pain in 45 cases, moderate pain in 25 cases, painless and severe pain in 0 cases, (9.3±3.2) d, respectively. In the interrupted suture group, the above indicators were 39 cases of mild pain, 12 cases of moderate pain, 0 cases of painless and severe pain, (8.7±2.1) d, and there was no statistical significance between the two groups ( Z=-1.431, P>0.05, t=1.149, P>0.05). In the continuous suture group, postoperative abdominal distension occurred in 8 cases, nausea and vomiting in 32 cases, gastroesophageal reflux in 17 cases by upper digestive tract imaging, contrast agent slowly passed through the residual stomach/anastomotic site in 14 cases, gastric volvulus in 6 cases, and no postoperative infection or anastomotic leakage occurred. In the interrupted suture group, the above indexes were 10 cases, 25 cases, 14 cases, 10 cases, gastric volvulus in 1 cases, and no postoperative infection or anastomotic leakage occurred. There was no significant difference in the above indicators between the two groups ( χ2=1.559, 0.010, 0.155, 0.003, 1.308, P>0.05). Conclusions:In laparoscopic sleeve gastrectomy and omentopexy, there is no significant difference between the continuous suture and interrupted suture in terms of operation time, intraoperative blood loss and postoperative complications. The surgeon can choose a suitable suture method based on his own judgment and experience.

OBJECTIVE: To explore the prevalence and characteristics of chromosomal abnormalities in abortuses during early pregnancy with single nucleotide polymorphism microarray (SNP-array). METHODS: For 520 abortuses, copy number variations (CNVs) in chorionic villi were analyzed with SNP-array. RESULTS: In 510 (98.1%) of the samples, the analysis was successful. Among these, 57.6% (294/510) of the samples were found to harbor clinically significant chromosomal abnormalities. 38.8% of the samples (198/510) had a normal result. 2.4% (12/510) of the samples harbored benign CNVs, and 1.2% (6/510) harbored variants of uncertain significance (VOUS). Aneuploidies, polyploidies, pathogenic CNVs and uniparental disomies (UPD) had accounted for 75.2% (221/294), 13.9% (41/294), 8.2% (24/294), and 2.7% (8/294) of the samples, respectively. 45,XO was the most common finding, which was followed by trisomy 16 and trisomy 22. 69,XXY was the most common polyploidy. CONCLUSION Chromosomal abnormalities are the main cause for early miscarriage, among which aneuploidies are most common. The prevalence of aneuploidies is significantly increased among women over 35. SNP-array analysis has the advantage of high success rate, high resolution and great accuracy, but the clinical significance of microdeletions/microduplications found by SNP-array can be difficult for interpretation.

Objective To investigate the value of next-generation sequencing (NGS) technique for genetic analysis of spontaneous abortion. Methods From January to June 2017, 154 patients who visited the First Affiliated Hospital of Zhengzhou University for spontaneous abortion were enrolled. All abortion tissue samples were analyzed by both NGS combined with short tandem repeat (STR) and single nucleotide polymorphism array (SNP-array). Results of the two methods were compared by Chi-square or Fisher's exact test. Results (1) Chromosomal abnormalities were detected in 109 of the 154 cases (70.7%), including 52 (47.7%) of numerical chromosomal abnormalities, 49 (45.0%) of structural chromosomal abnormalities, six (5.5%) of mosaicism, and two (1.8%) of uniparental disomy (UPD). In those 52 cases of numerical chromosome abnormalities, there were 45 of chromosome aneuploidy and seven of polyploidy. The top three numerical chromosomal abnormalities were 45,X (27.0%, 14/52), trisomy 22 (9.6%, 5/52) and trisomy 16 (7.7%, 4/52). Forty-nine structural abnormality cases carried 67 copy number variations (CNV), including 13 pathogenic CNV (pCNV, 19.4%), 24 variants of unknown clinical significance (35.8%) and 30 benign CNV (44.8%). In those 13 pCNVs, two were responsible for microdeletion and microduplication syndromes. (2) SNP-array was successful in 152 cases, but failed in two (1.3%) due to genomic DNA <200 ng. However, NGS technology was successful in all 154 cases and identified chromosomal abnormalities in the two cases that SNP-array had failed. No statistically significant difference was shown in the detection rate of chromosomal abnormalities between SNP-array and NGS technology [70.4% (107/152) vs 67.5% (104/154), χ2=0.293, P=0.588]. (3) No significant difference in the detection of chromosome aneuploidy (six cases in each group, 3.9% vs 3.9%) and mosaicism (45 cases in each group, 29.2% vs 29.6%) was found between NGS technology and SNP-array. Three cases of polyploidy (69, XXX) and two of UPD were identified by SNP-array, but not by NGS. When combined with STR, NGS was able to detect all three cases of polyploidy (69, XXX). (4) Forty-seven structural abnormality cases detected by SNP-array carried 53 CNVs, and 49 detected by NGS carried 67 CNVs. (5) NGS detected ten, three and one more CNVs than SNP-array did when the genome lengths were 100-<500, 500-<1 000 and ≥1 000 kb, respectively. Conclusions NGS can be used to detect chromosomal aneuploidy and mosaicism that can be identified by SNP-array with fewer limitations on total amount of genome. Moreover, CNVs that fail to be identified by SNP-array can also be detected by NGS. When combined with STR, NGS can effectively detect chromosomal polyploidy. Therefore, NGS could be a potential genetic analysis method for spontaneous abortion and of importance for genetic counseling.
