As one of the key enzymes in cell metabolism, the activity of citrate synthase 3 (CS3) regulates the substance and energy metabolism of organisms. The protein members of CS3 family were identified from the whole genome of apple, and bioinformatics analysis was performed and expression patterns were analyzed to provide a theoretical basis for studying the potential function of CS3 gene in apple. BLASTp was used to identify members of the apple CS3 family based on the GDR database, and the basic information of CS3 protein sequence, subcellular localization, domain composition, phylogenetic relationship and chromosome localization were analyzed by Pfam, SMART, MEGA5.0, clustalx.exe, ExPASy Proteomics Server, MEGAX, SOPMA, MEME, WoLF PSORT and other software. The tissue expression and inducible expression characteristics of 6 CS3 genes in apple were determined by acid content and real-time fluorescence quantitative polymerase chain reaction (qRT-PCR). Apple CS3 gene family contains 6 members, and these CS3 proteins contain 473-608 amino acid residues, with isoelectric point distribution between 7.21 and 8.82. Subcellular localization results showed that CS3 protein was located in mitochondria and chloroplasts, respectively. Phylogenetic analysis divided them into 3 categories, and the number of genes in each subfamily was 2. Chromosome localization analysis showed that CS3 gene was distributed on different chromosomes of apple. The secondary structure of protein is mainly α-helix, followed by random curling, and the proportion of β-angle is the smallest. The 6 members were all expressed in different apple tissues. The overall expression trend from high to low was the highest relative expression content of MdCS3.4, followed by MdCS3.6, and the relative expression level of other members was in the order of MdCS3.3 > MdCS3.2 > MdCS3.1 > MdCS3.5. qRT-PCR results showed that MdCS3.1 and MdCS3.3 genes had the highest relative expression in the pulp of 'Chengji No. 1' with low acid content, and MdCS3.2 and MdCS3.3 genes in the pulp of 'Asda' with higher acid content had the highest relative expression. Therefore, in this study, the relative expression of CS3 gene in apple cultivars with different acid content in different apple varieties was detected, and its role in apple fruit acid synthesis was analyzed. The experimental results showed that the relative expression of CS3 gene in different apple varieties was different, which provided a reference for the subsequent study of the quality formation mechanism of apple.

ObjectiveTo observe the efficacy and safety of sertraline combined with low-dose olanzapine in the treatment of depression and anxiety comorbidity and its effect on sleep quality， so as to provide references for the related clinical treatment. MethodsA total of 121 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for depressive episode and generalized anxiety disorder in The Third People's Hospital of Tianshui and the Sanatorium for Mental Illness of Veterans in Tianshui from October 2019 to August 2020 were enrolled， and they were divided into two groups according to the random number table method. Study group （n=61） received sertraline combined with low-dose olanzapine， while control group （n=60） received sertraline only. Then the disease severity degree， sleep quality and adverse reactions were assessed using Hamilton Depression Scale - 17 item （HAMD-17）， Hamilton Anxiety Scale （HAMA）， Pittsburgh Sleep Quality Index （PSQI） and Treatment Emergent Symptom Scale （TESS） at the baseline， 1^st， 2^nd， 4^th， 6^th and 8^th weekend， respectively. ResultsPost-treatment HAMD-17， HAMA and PSQI scores in both groups were lower than those before treatment （P<0.05）. At each time point after treatment， HAMD-17， HAMA and PSQI scores of study group were lower than those of control group， with statistical significance （P<0.05）. ConclusionSertraline alone and its combination with low-dose olanzapine are both effective in the treatment of depression and anxiety comorbidity， while the combination therapy achieves better efficacy and higher safety in alleviating anxiety and insomnia symptoms.

Objective: To improve clinical management of maternal and neonatal listeriosis through analyzing the clinical characteristics and antibiotic treatment. Methods: A retrospective analysis of 26 cases of listeriosis, including their demographic and clinical features, was conducted, involving 16 pregnant women from Civil Aviation General Hospital, Xiamen Humanity Hospital, Tongzhou Maternal and Child Health Hospital of Beijing, Beijing Tiantan Hospital, Tangshan Maternal and Child Health Hospital, the Fourth Hospital of Tianshui City from October, 2011 to May, 2018, and 10 newborns from the Fourth Hospital of Tianshui City, Tangshan Maternal and Child Health Hospital, Zhengzhou Children's Hospital from February, 2016 to April 2018. Descriptive methods were used for data analysis. Results: (1) Among the 16 gravidas, one, five and 10 developed the infection in the 1st, 2nd and 3rd trimester of pregnancy, respectively, and eight had pregnancy complications. Furthermore, all of them developed fever [(38.9±0.5) ℃]. Symptoms such as cough, nasal congestion, runny nose, sore throat, dizziness, headache and other flu-like symptoms were observed in six cases. Gastrointestinal symptoms and flu-like symptoms were presented in four. Fetal distress, tachycardia and decreased fetal movement occurred in 11 cases. Elevated C-reactive protein and white blood cell count were detected in 16 and 14, respectively. Eight underwent placental pathological examination which shown various degrees of pathological changes, including neutrophil infiltration, acute chorioamnionitis and inflammatory necrosis. The main empirical antibiotic treatment for the 16 patients was cephalosporins and only four covered Listeria monocytogenes. Only two delivered at term, while the others (14/16) ended in miscarriage, premature delivery or stillbirth. (2) Among the 10 newborns with listeriosis, there were eight early-onset infections and two late-onset infections. All of them were febrile [(38.6±0.6)℃]. Six had cyanosis, groaning, foaming and three concave sign; five showed shortness of breath; meningitis and skin rash were found in one, respectively. All had elevated white blood cell and C-reactive protein. Six received antibiotics covering Listeria monocytogenes during the initial empirical treatment. Four were treated with cephalosporins alone, one of which died after the treatment was withdrawn. One was cured by initial treatment with meropenem alone, while eight recovered after adjustment of treatment with ampicillin, penicillin, meropenem, vancomycin alone, or meropenem combined with ampicillin or vancomycin. (3) The isolates that were susceptible to penicillin, ampicillin and meropenem accounted for 96.1% (25/26) all together and 88.5% (23/26) were susceptible to compound sulfamethoxazole. Conclusions There is no specific clinical manifestations of maternal or neonatal listeriosis. Maternal listeriosis is often characterized by acute onset and high incidence of adverse pregnancy outcomes.
