ObjectiveTo analyze the suicidal behavior in hospitalized patients with major depression and its influencing factors. MethodsA total of 1 000 patients with major depression admitted to our hospital from January 2017 to July 2021 were selected as the research subjects to investigate the status quo of suicidal behavior of the enrolled patients. According to the survey results， the patients were divided into suicidal behavior group and non-suicidal behavior group， and the related factors affecting their suicidal behavior. ResultsA total of 511 cases （51.10%） of the patients with major depression committed suicide in hospital， including 271 cases （27.10%） of suicidal ideation， 186 cases （18.60%） of attempted suicide， and 54 cases （5.40%） of suicide death. 489 patients （48.90%） did not commit suicide. Univariate analysis showed that there were significant differences in age， gender， marital status， loss of interest or pleasure， anxiety， sense of worthlessness or self-guilt， sleep status， personality， depressive episodes and paranoia between the suicidal behavior group and the non-suicidal behavior group （all P<0.05）. Logistic multifactorial regression analysis showed that age ≤28 years （OR=1.54）， female （OR=1.93）， anxiety （OR=1.61）， sense of worthlessness or self-guilt （OR=1.85） and paranoia （OR=2.15） were all independent predictors of suicidal behavior in the patients with major depression. ConclusionThe incidence of nosocomial suicide in patients with major depression is high. Early onset age， female， anxiety， sense of worthlessness or self-guilt， more depressive episodes and paranoia are independent risk predictors of suicide in patients with major depression. This finding can be used for clinical intervention to reduce the occurrence of suicide in patients.

Objective:To analyze the prognosis of glucose metabolism and its impacting factors at 6-12 weeks postpartum in patients with abnormal blood glucose during pregnancy.Methods:In this cross-sectional study, a total of 192 patients with abnormal blood glucose during pregnancy enrolled and delivered in the maternity clinic of Daxing Teaching Hospital of Capital Medical University from December 1, 2019 to December 31, 2020 were collected. The 75 g oral glucose tolerance test (OGTT) was applied for diabetes screening at 6-12 weeks after delivery. According to the results of postpartum blood glucose, the patients were divided into two groups: postpartum normal blood glucose group (148 cases) and abnormal blood glucose group (44 cases). Hypothesis testing was used to compare the clinical data before, during and after the pregnancy between the two groups. Multi-factor logistic regression was performed to analyze the influencing factors of postpartum abnormal blood glucose in patients with abnormal blood glucose during pregnancy.Results:Among the 192 patients with abnormal blood glucose during pregnancy, the incidence of postpartum abnormal blood glucose was 22.92% (44/192), including 6 cases of diabetes mellitus (DM) (13.64%), 38 cases of impaired glucose tolerance (IGT) (86.36%). Neck circumference, waist circumference, multiparous women and insulin use during pregnancy in postpartum abnormal blood glucose group were all significantly higher than those in postpartum normal blood glucose group [34.25(33.00, 36.00) vs 33.55 (32.00, 35.00) cm, 87.00 (82.00, 93.00) vs 84.00 (78.00, 90.00) cm, 54.55% vs 37.16%, 18.18% vs 6.76%] (all P<0.05). Neck circumference ( OR=1.315, 95% CI: 1.026-1.685), multiparous women ( OR=2.261, 95% CI: 1.057-4.836), insulin use during pregnancy ( OR=3.767, 95% CI: 1.236-11.478) were positively correlated with the occurrence of postpartum abnormal blood glucose (all P<0.05). Conclusions:The incidence of postpartum abnormal blood glucose is high at 6-12 weeks postpartum in patients with abnormal blood glucose during pregnancy. Neck circumference, waist circumference, parity and insulin use during pregnancy are important impacting factors of postpartum abnormal blood glucose.

Organic acids are organic compounds that can be synthesized using biological systems. They often contain one or more low molecular weight acidic groups, such as carboxyl group and sulphonic group. Organic acids are widely used in food, agriculture, medicine, bio-based materials industry and other fields. Yeast has unique advantages of biosafety, strong stress resistance, wide substrate spectrum, convenient genetic transformation, and mature large-scale culture technology. Therefore, it is appealing to produce organic acids by yeast. However, challenges such as low concentration, many by-products and low fermentation efficiency still exist. With the development of yeast metabolic engineering and synthetic biology technology, rapid progress has been made in this field recently. Here we summarize the progress of biosynthesis of 11 organic acids by yeast. These organic acids include bulk carboxylic acids and high-value organic acids that can be produced naturally or heterologously. Finally, future prospects in this field were proposed.

There was no statistically significant difference in FEV 1 between two groups ( P>0.05) . Conclusions:The intervention plan for inhalation medication compliance in elderly patients with chronic obstructive pulmonary disease based on the integrated theory of health behavior changes can improve their inhalation medication compliance and improve their quality of life.

Epidermal barrier defects and immune abnormalities are the main pathophysiological changes in the development of atopic dermatitis (AD) . Skin keratinocytes can release a variety of inflammatory factors and mediators under the treatment with various harmful factors. Three epithelium-derived cytokines interleukin (IL) -33, IL-25 and thymic stromal lymphopoietin are considered to be effective inducers of Th2 immune response in skin or mucosal barrier, which can activate immune cells, cause the secretion of Th2 cytokines, enhance the Th2 immune response, and participate in the occurrence and development of AD. This review focuses on the role of the above 3 epithelium-derived cytokines in the pathogenesis of AD.

SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.

Objective:To investigate the abnormal patterns of spontaneous neural activity of patients with type 2 diabetes comorbid depression (T2DD) by using resting-state functional magnetic resonance imaging (rs-fMRI) fractional amplitude of low-frequency (fALFF) analysis, and determine the neuroimaging features of brain damage in T2DD patients.Methods:A perspective study was performed. Fifty-nine type 2 diabetes mellitus (T2DM) patients and 52 T2DD patients, admitted to and accepted treatment in Department of Endocrinology of our hospital from November 2017 to November 2020, were chosen; another 57 healthy controls matched with gender, age and education level, admitted to our hospital at the same time period were enrolled. Their clinical data, neuropsychological test and rs-fMRI data were collected; whole brain fALFF values were calculated, and fALFF values of different brain regions were compared in subjects of the 3 groups. Pearson correlation analysis was used to verify the correlations of fALFF values with clinical variables and neuropsychological scale scores.Results:The fALFF values in bilateral precuneus showed significant difference among the three groups ( P<0.05). The fALFF values in bilateral precuneus of the T2DD and T2DM groups were significantly lower than those in heathy control group ( P<0.05), and those in the T2DD group were lower than those in the T2DM group without significant difference ( P>0.05). Pearson correlation analysis showed that there were no correlations of fALFF values with clinical data and psychometric scale scores in T2DD group and T2DM group ( P>0.05). Conclusion:The abnormal patterns of spontaneous brain activity in the bilateral precuneus may be the neuroimaging markers of brain damage in T2DD patients.
