Objective To find potential biomarkers and analyzing metabolic pathways of the treatment by honey-processed Hedysari Radix,the cecal contents of rats with spleen-Qi deficiency were used as samples for analysis.Methods Sixty male SD rats were randomly divided into blank,model,experimental and control groups.The rats in other groups except the control group were carried out by using the three-factor compound modeling method of bitter-cold diarrhea,excessive exertion and hunger and satiety disorders.Experimental group was given 12.60 g·kg-1 honey-processed Hedysari Radix;control group was given 0.63 g·kg-1 lactobacillus bifidum triplex tabletsa;control and model groups received with equal volume of distilled water for a total of 15 days.Measure body weight,anal temperature,immune organ index of rats.Ultra-pressure liquid chromatography-quadrupole-exactive-mass spectrometry technology was used to measure the levels of endogenous metabolites in cecum contents.Orthogonal partial least squares discriminant analysis and database"Kyoto Encyclopedia of Genes and Genomes"were used to identify potential differential metabolites and possible metabolic pathways.Results After the intervention,the average body weight of the experimental,control,model and blank groups was(216.87±7.85),(210.96±9.03),(159.47±5.18)and(293.51±22.98)g;anal temperature was(36.14±0.48),(35.40±0.64),(34.50±0.78)and(36.61±0.34)℃;the thymus indexes were(1.19±0.20),(1.24±0.25),(0.47±0.15)and(1.31±0.21)mg·g-1;the spleen indexes were(1.95±0.33),(2.18±0.28),(1.61±0.27)and(2.29±0.24)mg·g-1.Compared with the model group,the above indexes of the experimental group and the control group were significantly increased(all P＜0.01).A total of 14 potential biomarkers of Honey-processed Hedysari Radix in treating spleen-Qi deficiency syndrome were screened out in this study,which mainly involved amino acid metabolism such as tryptophan and glutamate,riboflavin metabolism and adenosine 5'-monophosphate-activated protein kinase metabolism.Conclusion Honey-processed Hedysari Radix can further protect the intestinal mucosal barrier and reduce the intestinal inflammatory response by improving the metabolic level of cecum contents in rats with spleen-Qi deficiency in cecum contents,thus exerting the effect of strengthening the spleen and tonifying the Qi.

The main sources of natural drugs include various biological species such as plants, animals, and microorganisms. The accurate identification of these species is the bedrock of natural drug development. We propose a novel method of species identification in this paper: analysis of whole-genome (AGE), a molecular diagnostic method used to identify species by finding species-specific sequences from the whole genome and precisely recognizing the specific target sequences. We elaborate that the principle for species identification based on AGE is that the genome sequences of diverse species must differ and divide the implementation strategy of the method into two levels of research and application. Based on our analysis of its characteristics, the method would have the potential advantages of reliable principle, high specificity, and wide applicability. Moreover, three crucial concerns related to building method systems including genome acquisition, bioinformatics analysis, and database construction, are further discussed. In summary, we offer theoretical underpinnings and methodological guidance for the development of bioinformatics software and commercial kits, indicating AGE has great application potential in objects, subjects, and industries.

OBJECTIVE: To investigate the effects and mechanisms of Kindlin-2 on uterus development and reproductive capacity in female mice. METHODS: Cdh16-Cre tool mice and Kindlin-2^flox/flox mice were used to construct the mouse model of uterus specific knockout of Kindlin-2, and the effects of Kindlin-2 deletion on uterine development and reproduction capacity of female mice were observed. High expression and knockdown of Kindlin-2 in endometrial cancer cell lines HEC-1 and Ish were used to detect the regulation of mammalian target of rapamycin (mTOR) signaling pathway. In addition, uterine proteins of the female mice with specific knockout of Kindlin-2 and female mice in the control group were extracted to detect the protein levels of key molecules of mTOR signaling pathway and Hippo signaling pathway. RESULTS: The mouse model of uterine specific knockout of Kindlin-2 was successfully constructed. The knockout efficiency of Kindlin-2 in mouse uterus was identified and verified by mouse tail polymerase chain reaction (PCR), Western blot protein identification, immunohistochemical staining (IHC) and other methods. Compared with the control group, the female mice with uterus specific deletion of Kindlin-2 lost weight, seriously impaired reproductive ability, and the number of newborn mice decreased, but the proportion of the female mice and male mice in the newborn mice did not change. Hematoxylin eosin staining (HE) experiment showed that the endometrium of Kindlin-2 knockout group was incomplete and the thickness of uterine wall became thinner. In terms of mechanism, the deletion of Kindlin-2 in endo-metrial cancer cell lines HEC-1 and Ish could downregulate the protein levels of mTOR, phosphorylated mTOR, adenosine monophosphate-activated protein kinase (AMPK), phosphorylated AMPK and phosphorylated ribosomal protein S6 (S6), and the mTOR signal pathway was inhibited. It was found that the specific deletion of Kindlin-2 could upregulate the protein levels of Mps one binding 1 (MOB1) and phosphorylated Yes-associated protein (YAP) in the uterus of the female mice, and the Hippo signal pathway was activated. CONCLUSION Kindlin-2 inhibits the development of uterus by inhibiting mTOR signal pathway and activating Hippo signal pathway, thereby inhibiting the fertility of female mice.

AIM:To evaluate the effects of intermittent exotropia(IXT)on the quality of life of children and their parents using the Chinese version of intermittent exotropia questionnaires(CIXTQ).METHODS: The scores of CIXTQ were collected from IXT children and the same number of age-matched control children in department of ophthalmology, Nanjing Children's Hospital from June 2020 to June 2021. They were the Chinese version of intermittent exotropia questionnaires scores(CIXTQ, for children to assess their health related quality of life), the parental proxy CIXTQ(pp-CIXTQ, for parents to assess children's life quality)scores and the parent CIXTQ(p-CIXTQ, for parents to assess their life quality)scores. To explore: 1)The differences in the CIXTQ, pp-CIXTQ and p-CIXTQ scores between IXT children and the normal children; 2)The relationship between the CIXTQ and pp-CIXTQ scores in IXT children; 3)The factors affecting the quality of life in children with IXT.RESULTS: A total of 156 patients with IXT and 156 age-matched normal children were included. CIXTQ scores in the children with IXT group was lower than that in the control group(t=-12.915, P<0.001). In IXT group, there was no difference observed in CIXTQ or pp-CIXTQ scores(t=-0.718, P=0.473). As suggested by item-level analysis, children in the IXT group were more concerned about how others think of them and their vision, whereas parents were more concerned about whether the child needs surgery, and whether the permanent damage of strabism caused to the eyes of their children and whether strabismus affects their social life.CONCLUSION: The CIXTQ performed better in distinguishing the children with IXT and those with normal condition, and it can accurately predict the impact of IXT on children, and benefit to make personalized treatment regimens.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

According to human carboxylesterase 2(hCE2) inhibitors reported in the literature, the pharmacophore model of hCE2 inhibitors was developed using HipHop module in Discovery Studio 2016. The optimized pharmacophore model, which was validated by test set, contained two hydrophobic, one hydrogen bond acceptor, and one aromatic ring features. Using the pharmacophore model established, 5 potential hCE2 inhibitors(CS-1,CS-2,CS-3,CS-6 and CS-8) were screened from 20 compounds isolated from the roots of Paeonia lactiflora, which were further confirmed in vitro, with the IC_(50) values of 5.04, 5.21, 5.95, 6.64 and 7.94 μmol·L~(-1), respectively. The results demonstrated that the pharmacophore model exerted excellent forecasting ability with high precision, which could be applied to screen novel hCE2 inhibitors from Chinese medicinal materials.

Objective:To analyze any changes in the functional connectivity between the seed points of the dorsolateral prefrontal cortex (DLPFC) and the whole brain, as well as any fluctuations in the low-frequency amplitude among persons with post-stroke depression (PSD). The aim was to develop correlations among functional imaging results, clinical scales, and inflammation indicators including high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), interleukin 2 (IL-2), interleukin 10 (IL-10), interleukin 17a (IL-17a) and interferon-γ (IFN-γ).Methods:Between 2016 and 2020, 55 ischemic stroke survivors were tested. The 28 scoring 7 or more on the Hamilton Depression Scale (HAMD-17) formed the PSD group, while the 27 others formed the control group. Functional magnetic resonance images were collected, and serum inflammation indicators were determined.Results:When seed points in the left DLPFC were used, in the PSD group the frontal cortex (FC) decreased in one cluster, with a voxel of 129mm3 and the MNI coordinates (x=9, y=30, z=33) indicating that the anatomical automatic labeling (AAL) brain regions were the Cingulum_Ant_L, Cingulum_Mid_R and the frontal_Sup_Medial_L. When the right DLPFC was used as the seed point the FC again decreased in one cluster, with voxels of 44mm 3 and the MNI coordinates (x=-27, y=12, z=47) referring to the AAL brain region of the frontal_Mid_L. In the PSD group, the FC value of abnormal brain areas with the R-DLPFC as the seed point was positively correlated with time since stroke. In the control group, the FC value of abnormal brain areas with L-DLPFC as the seed point was negatively correlated with MoCA, while with R-DLPFC as the seed point it was positively correlated with IFN-γ. The FC values of abnormal areas of the brain showed no significant correlation with other clinical scales, inflammation indicators or lesion volume. Conclusion:Abnormal functional connections within the executive control network and between the salience networks may participate in the mechanism of PSD, and may be related to the time since stroke, cognitive functioning, and IFN-γ levels.

Purpose: This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. Methods: An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. Results: In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. Conclusions In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.
