Background: As a public health emergency of international concern, the COVID-19 outbreak has had a tremendous impact on patients' psychological health. However, studies on psychological interventions in patients with COVID-19 are relatively rare.Objectives: This study examined the effectiveness of Cognitive Behavioral Therapy (CBT) in relieving patients' psychological distress during the COVID-19 epidemic.Methods: Ninety-three eligible participants selected by cluster sampling were randomized to an intervention group (N = 47) and a control group (N = 46). Participants in the control group received routine treatment according to the Chinese Management Guidelines for COVID-19, while participants in the intervention group received routine treatment with additional CBT. The Chinese Version of Depression Anxiety and Stress Scale-21 (DASS-21) was used to evaluate depression, anxiety, and stress for all participants at baseline and post-intervention. Two-sided t-test, and proportion tests were used to examine the differences between the intervention and control group for each DASS-21 indicator. Univariate linear regression was used to examine the association between chronic disease status and change in each DASS-21 indicator after intervention. Two-way scatter plots were generated to show the association of the length of hospital stay and the changes of each DASS-21 indicator by intervention and control groups.Results: Significant decreases in means were found for scales of depression, anxiety, stress and total DASS-21 in both intervention (p < 0.001) and control group (p = 0.001), with participants in the intervention group having a bigger reduction in means. After the intervention, more participants in the intervention group had no depression or anxiety symptoms than in the control group, but no statistical differences were found (p > 0.05). Compared with participants with chronic disease, participants with no chronic disease had a significantly larger reduction of total DASS-21 scale (coefficient = −4.74, 95% CI: −9.31; −0.17).The length of hospital stay was significantly associated with a greater increase in anxiety scale in the intervention group (p = 0.005), whilst no significant association was found in the control group (p = 0.29).Li et al. Psychological Intervention on COVID-19 PatientsConclusions: The patients with COVID-19 experienced high levels of anxiety, depression and stress. Our study result highlights the effectiveness of CBT in improving the psychological health among patients with COVID-19, also suggests that CBT should be focused on patients with chronic disease and those who have longer hospital stays. These results have important implications in clinical practice in improving psychological health in the context of COVID-19 pandemic. Trial Registration: ISRCTN68675756.

Uterine leiomyoma is the most common tumor of the female genital tract and the leading cause of hysterectomy. Although progesterone stimulates the proliferation of uterine leiomyoma cells, the mechanism of progesterone action is not well understood. We used chromatin immunoprecipitation (ChIP)-cloning approach to identify progesterone receptor (PR) target genes in primary uterine leiomyoma smooth muscle cells. We identified 18 novel PR-binding sites, one of which was located 20.5 kb upstream of the transcriptional start site of the Krüppel-like transcription factor 11 (KLF11) gene. KLF11 mRNA levels were minimally downregulated by progesterone but robustly upregulated by the progesterone antagonist RU486. Luciferase reporter assays showed significant baseline and RU486-inducible promoter activity in the KLF11 basal promoter or distal PR-binding region, both of which contained multiple Sp1-binding sequences but lacked classic progesterone response elements. RU486 stimulated recruitment of Sp1, RNA polymerase II, PR, and the coactivators SRC-1 and SRC-2 to the distal region and basal promoter. siRNA knockdown of PR increased KLF11 expression, whereas knockdown of KLF11 increased leiomyoma cell proliferation and abolished the antiproliferative effect of RU486. In vivo, KLF11 expression was significantly lower in leiomyoma tissues compared with adjacent myometrial tissues. Taken together, using a ChIP-cloning approach, we uncovered KLF11 as an integrator of PR signaling and proliferation in uterine leiomyoma cells.
Multiple drug resistance is reported to be a major obstacle in treatment of osteosarcoma (OS). Research has demonstrated that small subsets of cells called cancer stem cells (CSCs) are responsible for multiple drug resistance. CSCs are potential targets for reversing chemoresistance. In the present study, we compared cisplatin sensitivity between OS stem cells and OS non-stem cells. We confirmed that OS stem cells showed significant cisplatin-resistance compared with the OS non-CSCs. Mechanically, we proved that overexpression of the pyruvate kinase isoenzyme M2 (PKM2) was responsible for the resistance to cisplatin in OS stem cells. As a potential strategy, we found that co-treatment with metformin significantly decreased the half maximal inhibitory concentration (IC50) of cisplatin to HOS OS stem cells by downregulating the expression of PKM2. PKM2 downregulation resulted in, metformin inhibited glucose uptake, lactate production and ATP production in HOS CSCs. Therefore, metformin impaired the resistance of HOS CSCs to cisplatin and promoted cisplatin-induced apoptosis. In addition, antitumor effects of other chemotherapeutic drugs such as doxorubicin and 5-fluorouracil were proved to be enhanced by metformin on OS stem cells.
Long non-coding RNAs (lncRNAs) are aberrantly expressed in various cancers. Fer-1-like protein 4 (FER1L4), one of lncRNAs, plays a role as tumor suppressor in various human cancers and can be regulated by microRNA. However, the role and function of FER1L4 in human hepatocellular carcinoma (HCC) remains unknown. The aim of the present study was to annotate the role of FER1L4 and its clinical value in HCC. In the present study, we found that FER1L4 was lowly expressed in HCC tissue specimens as well as in malignant HCC cell lines, while the situation is opposite in miR-106a-5p. We found that down-regulated FER1L4 increased the expression of miR-106a-5p significantly and there was a reciprocal repression between FER1L4 and miR-106a-5p. Moreover, we identified FER1L4 as a target of miR-106a-5p by using dual-luciferase reporter assay. Knockdown of FER1L4 promoted the malignancy of HCC cells, including proliferation, migration, and invasion, and inhibited cell apoptosis. We also found that FER1L4 functions as a tumor suppressor in vivo. Together, these results suggest that FER1L4 could exert a tumor suppressive impact on HCC, which at least, in part, through suppressing miR-106a-5p expression. FER1L4, as well as miR-106a-5p, can predict the clinical prognosis of HCC alone or combined, which may be a novel therapeutic target for treating HCC.
Traditional bullying and cyberbullying have become serious worldwide issues. The meta-analysis in this article took a cross-cultural perspective to explore whether there were any differences between the effects of cyber victimization and traditional victimization on the presence of depression and anxiety in children and adolescents and to examine the effects of moderators in explaining these differences/similarities. Fifty-six empirical studies (generating 148 independent samples) were included with a total sample size of 214,819 participants. The results indicated that the effects of cyber victimization and the subtypes of traditional victimization on anxiety were significantly different, and there was a marginally significant difference for depression. The moderating effects of country of origin were found to be significant for depression, with the mean effect size in North America being significantly higher than in China and Europe, which suggested that culture was an important factor. The moderating effects of age were also found to be significant for the relationships between traditional victimization and depression, traditional victimization and anxiety, cyber victimization and depression, and cyber victimization and anxiety. In addition, the effect size for cyber victimization and depression has increased in more recent publication years.
Objective To determine the expression and function of the microRNA-29 family (miR-29a, 29b, 29c) in human leiomyoma and myometrium. Study Design Basic Science Experimental Design Setting Academic medical center Patients Women undergoing surgery for symptomatic uterine fibroids. Interventions Overexpression and knockdown of miR-29a, 29b, and 29c in primary leiomyoma and myometrial cells. Main outcome measures (1) Expression of the miRNA-29 family members in vivo in leiomyoma versus myometrium; (2) Major fibrillar collagen (I, II, III) expression in leiomyoma and myometrial cells with manipulation of miR-29 species. Results Members of the miR-29 family (29a, 29b, 29c) are all down-regulated in leiomyoma versus myometrium in vivo. The expression of the miR-29 family can be successfully modulated in primary leiomyoma and myometrial cells. Overexpression of the miR-29 family in leiomyoma cells results in down-regulation of the major fibrillar collagens. Down-regulation of the miR-29 species in myometrium results in an increase in collagen type 3 deposition. Conclusions The miR-29 family is consistently down-regulated in leiomyoma compared to matched myometrial tissue. This down-regulation contributes to the increased collagen seen in leiomyomas versus myometrium. When miR-29 members are overexpressed in leiomyoma cells, protein levels of all of the major fibrillar collagens decrease. Mir-29 members are potential therapeutic targets in this highly prevalent condition.
The influence of the vitamin D receptor () gene for the risk of osteoporosis remains to be elucidated. The aim of the present study was to understand the distribution of various single-nucleotide polymorphisms (SNPs) within the gene and its association with the risk of osteoporosis. In total, 378 subjects without a genetic relationship were recruited to the study between January 2013 and July 2015. The subjects were divided into three groups, which were the normal (n=234), osteoporosis (n=65) and osteoporosis with osteoporotic fracture (n=79) groups. Three pertinent SNPs of the gene rs17879735 (I, Allele A/a, SNP C>A) were examined with polymerase chain reaction-restriction fragment length polymorphism. The bone mineral density (BMD) of the lumbar spine (L2-L4), femoral neck, Ward's and Tro was measured using dual-energy X-ray absorptiometry. The distributions of genotype frequencies aa, AA and Aa were 48.68, 42.86 and 8.46%, separately. Following analysis of each site, BMD, body mass index (BMI) and age, BMD for each site was negatively correlated with age (P<0.01) and positively correlated with BMI (P<0.01). Correction analysis revealed that there were significant differences in the Ward's triangle BMD among each genotype (P<0.05), in which the aa genotype exhibited the lower BMD (P<0.05). No significant difference was identified among the different genotypes in the occurrence of osteoporosis with osteoporotic fracture (P>0.05). In conclusion, these indicated that the geneI polymorphisms had an important role in the osteoporosis risk.
