Objective:To investigate the distribution and clinical significance of amniotic fluid karyotype results in 2 725 cases from southern Anhui.Methods:The karyotypes of amniotic fluid from 2 725 cases of second-trimester pregnant women treated in our hospital from Jan 2017 to Dec 2023 were collected.The annual abnormal detection rate and overall abnormal rate were analyzed.Meanwhile,the abnormal detection rate was compared among 8 groups of different clinical indication including adverse pregnancy history,advanced maternal age(≥35 years),high risk of Down syndrome screening,high risk of non-invasive prenatal testing(NIPT),nuchal translucency thickness(NT)≥2.5 mm,abnormal ultrasound findings,two or more concurrent positive indications,and others.The abnormal detection rate was calculated within high risk of Down syndrome screening and NIPT.Results:Significant differences in annual abnormal rates were observed from 2017 to 2023(χ2=19.705,P=0.003).Among 2 725 cases,233(8.55%)showed abnormal karyotypes.Among them,abnormal autosomal number was the most prevalent(4.41%,120/2 725),with inversion being the most common chromosome structural abnormality.Significant differences in abnormal rates were noted among the eight clinical indication groups(χ2=438.516,P＜0.01).No statistical difference was found in abnormal detection rates among the three high-risk subgroups of Down syndrome screening(χ2=0.323,P=0.851),while significant differences were observed within the high-risk subgroups of NIPT(χ2=100.901,P＜0.01).Polymorphisms were detected in 65 cases(2.38%).Conclusions:Chromosomal numerical and structural abnormalities have been detected in southern Anhui over the past seven years,with variations across subgroups.Karyotype analysis effectively detects second-trimester fetal chromosomal abnormalities,aiding in the prevention of birth defects and worthing clinical application.

Objective To explore the changes and influencing factors in patients' gastrointestinal symptoms and food tolerance before and after laparoscopic sleeve gastrectomy(LSG),and to provide a reference for the development of targeted gastrointestinal symptoms management program.Methods A convenience sampling method was used to select 125 patients who underwent LSG in the bariatric and metabolic surgery department of a tertiary-level hospital in Xuzhou City from June to November 2023 for a prospective observational study.The general information questionnaire,food tolerance questionnaire and Gastrointestinal Symptom Rating Scale(GSRS)were used to investigate at preoperative,3 months after surgery,and 6 months after surgery.Two-factor repeated measures variance analysis and generalized linear mixed model(GLMM)was used to analyze the influencing factors of gastrointestinal symptoms.Results 116 valid questionnaires were collected,and the GSRS scores of LSG patients at 3 time points were 21.67±5.80,23.28±4.33,and 21.22±3.18 respectively;the incidence rates of food intolerance were 0,32.75％,and 28.45％respectively.The patients' symptoms of bowel sounds,dysphagia,constipation,and dry stool were worse after surgery than before surgery(all P＜0.05),and the symptoms of bad breath,diarrhea,loose stools,and the need to defecate immediately were alleviated compared with symptoms before surgery(all P＜0.05).GLMM results showed that short meal times,poor food tolerance,and high school/technical secondary school education were risk factors for increasing gastrointestinal symptoms(all P＜0.05).Conclusion LSG could increase the prevalence of gastrointestinal symptoms such as dysphagia,dyspepsia,constipation and food intolerance.Medical staff should pay attention to the assessment of gastrointestinal symptoms in LSG patients,especially for patients with short meal time and poor food tolerance,strengthen postoperative follow-up,build targeted treatment and care plan,and prevent and reduce such uncomfortable symptoms.

Objective:To investigate the changes in synaptic transmission function of hippocampal dentate gyrus granule cells in depression model mice induced by chronic unpredictable mild stress (CUMS) and to explore the effect of exercise on it.Methods:Totally 48 SPF grade 7-week-old male C57BL/6J mice were randomly compartmentalised into control group (CTRL group), model group (CUMS group), model + exercise group (CUMS+ EXE group), and model + fluoxetine group (CUMS+ FLX group), with 12 mice in each group. CUMS method was used for preparating the depression model for 21 d. Mice in the CUMS+ EXE group were given roller locomotion training and mice in the CUMS+ FLX group were given fluoxetine intraperitoneally (10 mg/kg) daily during the modelling period, and the other two groups were administrated intraperitoneally with equal volume of 0.9% NaCl solution.Sucrose preference test (SPT), tail suspension test (TST) and forced swimming test (FST) were used to detect depressive-like behavior, and open field test (OFT) was used to detect anxiety-like behavior. Whole-cell recordings were used to detect spontaneous excitatory postsynaptic currents (sEPSC), spontaneous inhibitory postsynaptic currents (sIPSC), miniature excitatory postsynaptic currents (mEPSC), and miniature inhibitory postsynaptic currents (mIPSC) in hippocampal dentate gyrus granule cells.One-way ANONA was performed to analyze the data by SPSS 23.0.Results:(1) There were statistically significant differences among the 4 groups of mice in terms of activity time in the center, total distance of OFT and sugar preference rate( F=37.85, 18.41, 28.81 all P<0.01). The activity time in the center((47.81±3.51)s) and total distance((19.63±1.24)m) of OFT and sugar preference rate((55.63±9.11)%) in the CUMS group were lower than those in the CTRL group (all P<0.01), while those in the CUMS+ EXE group((59.87±3.25)s, (23.18±1.24)m, (69.03±8.22)% respectively) were higher than those in the CUMS group (all P<0.05).The sugar preference rate of the CUMS+ EXE group was lower than that in the CTRL group and CTRL+ FLX group (both P<0.01). The differences in immobility time of TST and FST were statistically significant among the 4 groups of mice ( F=113.70, 56.97, both P<0.01).

Objective:To investigate the effects of enriched environment on the behavior of depressive-like mice induced by chronic stress and the synaptic transmission function of hippocampal pyramidal neurons.Methods:Thirty-six 7-week-old SPF grade male C57BL/6J mice were divided into control group, model group and enriched environment group according to the random zone method, with 12 mice in each group.The mice in model group and enriched environment group were subjected to chronic unpredictable mild stress to establish depression models.During the modeling period, the mice in enriched environment group lived in the enriched environment for 6 hours per day, and lived in the routine environment for the rest time just like the mice in control group and model group.The depressive behaviors of mice were detected by sucrose preference test (SPT), forced swimming test (FST) and tail suspension test (TST).The motor function and anxious behavior of mice were detected by open field test (OFT) and the cognitive function was detected by Morris water maze test.In vitro electrophysiological techniques were used to record field excitatory post-synaptic potentials (fEPSP) in the hippocampus, and whole-cell recording was used to record spontaneous excitatory post-synaptic currents (sEPSC) and miniature excitatory post-synaptic currents (mEPSC) in hippocampal pyramidal neurons.Statistical analysis was conducted by SPSS 23.0 software.Multiple group comparisons of data were conducted by one-way ANOVA and repeated measures ANOVA.Results:(1) Behavioral results showed statistically significant differences among the three groups in terms of total activity time in the central area of OFT, sugar water preference rate of SPT and immobility time of TST and FST ( F=17.12, 26.07, 41.13, 60.18, all P<0.01).The activity time in the central area of OFT and sugar water preference rate of model group were lower than those in the control group (both P<0.01), and the immobility time of TST and FST were higher than those in the control group (both P<0.01).The activity time in the central area of OFT ((56.56±3.47) s) and sugar water preference rate ((71.22±8.37) %) of enriched environment group were higher than those in the model group((52.56±3.47) s, (59.53±8.72)%) (all P<0.05), and the immobility time of TST ((94.19±10.77) s) and FST ((76.98±12.10) s) were lower than those in the model group ((104.58±8.24) s, (111.41±9.56) s)(all P<0.05).(2)The results of spatial learning memory showed that there was a significant difference of group and time interaction effects for latency to find the platform ( F=12.02, P<0.01), and the latency to find the platform in model group was higher than that in control group and enriched environment group (both P<0.01).The results of spatial exploration showed that there were statistically significant differences in the target quadrant residence time and the times crossing the platform among the three groups( F=19.67, 20.27, both P<0.01).The both indexes in the model group were lower than those in control group and enriched environment group (all P<0.01).(3) The results of electrophysiological experiment showed that the interaction effect of fEPSP between groups and stimulations intensity among the three groups was significant( F=1.86, P<0.01).At the stimulation level of 150 mA and 200 mA, the fEPSP of the model group was lower than those of control group and enriched environment group (all P<0.05).(4)The results of the long-term potentiation(LTP) showed a statistically significant difference among the three groups( F=15.32, P<0.01).The LTP of the model group mice ((137.42±4.48)%) was lower than those of the control group ((156.62±4.79)%) and the enriched environment group ((147.86±9.14)%) (both P<0.05).(5) The whole-cell recordings results showed that there was a statistically significant difference in the frequencies of sEPSC and mEPSC among the three groups ( F=15.30, 13.72, both P<0.01).The sEPSC and mEPSC frequencies of the model group mice ((0.60±0.31) Hz, (0.63±0.26) Hz) were lower than those of the control group ((1.27±0.46) Hz, (1.02±0.28) Hz) and the enriched environment group ((0.96±0.45) Hz, (0.83±0.22) Hz) (all P<0.05). Conclusion:Environmental enrichment can alleviate the depressive behaviors induced by chronic stress and enhance cognitive performance, hippocampal pyramidal neuron synaptic transmission and synaptic plasticity in depressive-like mice.
