Association of macular corneal dystrophy with excessive cell senescence and apoptosis induced by the novel mutant CHST6.

Macular corneal dystrophy (MCD) is a rare form of hereditary corneal dystrophy caused by CHST6 mutations. Owing to the genetic heterogeneity and population differences among patients with MCD, the genetic cause of MCD has not been fully elucidated, and the pathogenesis underlying the genetic mutation is still unclear. In this study, Chinese families and sporadic patients were included as subjects, and clinical and genetic analyses were performed to detect novel CHST6 mutations. In addition, the underlying pathogenic mechanisms of MCD were investigated by in vitro cell experiments. Two consanguineously married families and 10 sporadic patients with MCD were enrolled. Direct sequencing of the CHST6 gene was performed in all the patients to identify novel mutations. Wild-type and mutant overexpression cell lines were constructed to study the effects of the mutation in vitro. The expressions of endoplasmic reticulum (ER) stress markers and apoptotic factors, cell senescence, and migration levels tests were performed in different overexpression cell lines. As a result, four novel mutations (R155Afs*66, S84Cfs*17, E71G, and E71Q) and 10 previously reported mutations in the CHST6 gene were identified. Among the reported mutations, the most frequent mutations detected in the patients were L21Rfs*88 (4/14) and L21H (4/14). All the novel mutations were absent in the 50 healthy controls and were predicted to alter highly conserved amino acids across the different species and considered to be "disease causing" by function prediction. The results of the in vitro cell experiment further demonstrated that the novel homozygous frameshift mutations (S84Cfs*17 and R155Afs*66) of CHST6 detected in the consanguineously married families could lead to truncated proteins with defect functions, higher ER stress and apoptotic levels, decreased cell migration, and excessive cell senescence in corneal stromal cells, thereby affecting the normal functions of corneal stromal cells. These changes might play important roles in corneal opacity, which is characteristic of corneas with MCD. Our study extended the existing spectrum of disease-causing mutations and further elucidated the underlying pathogenic mechanisms of MCD.

Relationship between patient safety culture and safety performance in nursing: The role of safety behaviour.

AIM: The aim of this work is to test the mediator role of patient safety behaviour between safety culture and safety performance among nurses. METHODS: This cross-sectional study was carried out between September and December 2017 in the nursing units of 10 primary hospitals, two secondary hospitals and two tertiary hospitals in Anhui Province, China. RESULTS: The study participants comprised 79 RNs from primary hospitals, 147 RNs from secondary hospitals and 242 RNs from tertiary hospitals. Most were female (97.6%) and married (73.1%), and their ages ranged from less than 25 years to retirement age. The sample included nurses working in several departments, including medicine (27.1%), surgery (14.3%), emergency (11.5%) and ICU (9%). Structural equation model analysis results showed that espoused values directly affected safety performance, and practised values affected safety performance through safety behaviour. CONCLUSION: Our hypothetical model noted that safety behaviour is a positive mediating factor of practised safety values affecting safety performance, suggesting that Chinese nursing managers should construct a patient safety culture that is guided and driven by appropriate values, which will ultimately be externalized as nurses' daily behaviour.

A Randomized, 8-Week Study of the Effects of Extended-Release Paliperidone and Olanzapine on Heart Rate Variability in Patients With Schizophrenia.

PURPOSE: This study aimed to explore the effect of extended-release paliperidone (paliperidone ER) and olanzapine on heart rate variability (HRV) in patients with schizophrenia. METHODS: A total of 106 patients with schizophrenia diagnosed by the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) were randomly divided into the paliperidone ER group or the olanzapine group for an 8-week clinical trial, with 53 patients in each group. The time domain and frequency domain analyses including the SD of all the R-R intervals in 24 hours (SDNN), the SD of the mean value of all the normal R-R intervals in every 5-minute interval within 24 hours (SDANN index), the mean value of the SD of all the normal R-R intervals in every 5-minute interval within 24 hours (SDNN index), the root mean square of successive R-R differences, the percentage of adjacent R-R intervals that differ by more than 50 milliseconds, high-frequency power (HF), low-frequency power (LF), and LF/HF were adopted to assess the HRV of patients at baseline and after treatment for 8 weeks in each group. The Positive and Negative Symptom Scale was used to evaluate the clinical efficacy. The incidence rates of adverse reactions were also calculated. RESULTS: In total, 48 patients in the paliperidone ER group and 45 patients in the olanzapine group completed the entire 8-week treatment. The SDNN, SDNN index, and SDANN index in the olanzapine group were significantly lower than those in the paliperidone ER group (P < 0.05) after treatment for 8 weeks, whereas their mean LF level was higher than that in the paliperidone ER group (P < 0.05) after completion of treatment. Patients in the olanzapine group showed a significant decrease in the SDNN, SDANN index, and SDNN index as well as a statistical increase in the LF and LF/HF in comparison with the pretreatment values (P < 0.05), whereas patients in the paliperidone ER group showed a decrease in the SDANN index and a statistical increase in the LF in comparison with the pretreatment values (P < 0.05). CONCLUSION: The HRV of patients with schizophrenia changes when they are administered with paliperidone ER or olanzapine, and more attention should be paid to their cardiac autonomic function when using these 2 antipsychotics.

Real-time Microwave Exposure Induces Calcium Efflux in Primary Hippocampal Neurons and Primary Cardiomyocytes.

OBJECTIVE: To detect the effects of microwave on calcium levels in primary hippocampal neurons and primary cardiomyocytes by the real-time microwave exposure combined with laser scanning confocal microscopy. METHODS: The primary hippocampal neurons and primary cardiomyocytes were cultured and labeled with probes, including Fluo-4 AM, Mag-Fluo-AM, and Rhod-2, to reflect the levels of whole calcium [Ca2+], endoplasmic reticulum calcium [Ca2+]ER, and mitochondrial calcium [Ca2+]MIT, respectively. Then, the cells were exposed to a pulsed microwave of 2.856 GHz with specific absorption rate (SAR) values of 0, 4, and 40 W/kg for 6 min to observe the changes in calcium levels. RESULTS: The results showed that the 4 and 40 W/kg microwave radiation caused a significant decrease in the levels of [Ca2+], [Ca2+]ER, and [Ca2+]MIT in primary hippocampal neurons. In the primary cardiomyocytes, only the 40 W/kg microwave radiation caused the decrease in the levels of [Ca2+], [Ca2+]ER, and [Ca2+]MIT. Primary hippocampal neurons were more sensitive to microwave exposure than primary cardiomyocytes. The mitochondria were more sensitive to microwave exposure than the endoplasmic reticulum. CONCLUSION: The calcium efflux was occurred during microwave exposure in primary hippocampal neurons and primary cardiomyocytes. Additionally, neurons and mitochondria were sensitive cells and organelle respectively.

Real-time Assessment of Cytosolic, Mitochondrial, and Nuclear Calcium Levels Change in Rat Pheochromocytoma Cells during Pulsed Microwave Exposure Using a Genetically Encoded Calcium Indicator.

Little information is available about the effects of exposure to pulsed microwaves on neuronal Ca2+ signaling under non-thermal conditions. In this study, rat pheochromocytoma (PC12) cells were exposed to pulsed microwaves for 6 min at a specific absorption rate (SAR) of 4 W/kg to assess possible real-time effects. During microwave exposure, free calcium dynamics in the cytosol, mitochondria, and nucleus of cells were monitored by time-lapse microfluorimetry using a genetically encoded calcium indicator (ratiometric-pericam, ratiometric-pericam-mt, and ratiometric-pericam-nu). We established a waveguide-based real-time microwave exposure system under accurately controlled environmental and dosimetric conditions and found no significant changes in the cytosolic, mitochondrial, or nuclear calcium levels in PC12 cells. These findings suggest that no dynamic changes occurred in [Ca2+]c, [Ca2+]m, or [Ca2+]n of PC12 cells at the non-thermal level.

Application of magnetically modified sewage sludge ash (SSA) in ionic dye adsorption.

Incineration is a traditional method of treating sewage sludge and the disposal of derived ash is a problem of secondary waste treatment. In this study, sewage sludge ash (SSA) was coated with ferrite through a ferrite process and then used as an adsorbent for ionic dyes (methylene blue [MB] and Procion Red MX-5B [PR]). The modified SSA possessed surface potential that provided electrostatic attraction toward MB and PR. Adsorbent FA10 (named on the basis of being produced from 10 g of SSA in the ferrite process) was used for the adsorption of MB. Ideal pH for adsorption was 9.0 and maximum adsorption capacity based on Langmuir isotherm equation was 22.03 mg/g. Adsorbent FA2.5 (named on the basis of being produced from 2.5 g of SSA in the ferrite process) was used for PR adsorption. Ideal pH for adsorption was 3.0 and the maximum adsorption capacity (calculated as above) was 28.82 mg/g. Kinetic results reveal that both MB and PR adsorption fit the pseudo-second-order kinetic model better than the pseudo-first-order model. The values of activation energy calculated from rate constants were 61.71 and 9.07 kJ/mol for MB and PR, respectively.

Effect of icariin on the transformation efficiency of induced pluripotent stem cells into sperm cells in vitro.

OBJECTIVE: To investigate the effect of icariin on the transformation efficiency of germ cell-like cells from mouse induced pluripotent stem cells into sperm cells in vitro. METHODS: Firstly, mouse induced pluripotent stem cells were induced and cultured to transform into germ cell-like cells, and the primordial germ cell-like cells were identified by Western blot and RT-PCR. Then, different concentrations of icariin (0.1µg/mL, 1µg/mL, 10µg/mL and 100µg/mL) were added into the culture medium, and the obtained primitive germ cell-like cells were cultured, Western blot and RT-PCR were used to identify the obtained sperm cells, the transformation efficiency was compared. RESULTS: The primordium germ cell-like cells obtained from mouse induced pluripotent stem cells in vitro specially expressed Oct-4 protein, C-kit protein, Mvh mRNA, Fragilis mRNA and Stella mRNA. The sperm cells were specially expressed VASA, SCP3 and γH2AX proteins. RT-PCR showed that the sperm cells were specially expressed Ddx4, Tp2 and Prm1 mRNA. Compared with the control group, the expression level of VASA protein (1.744±0.283, 2.882±0.373, 6.489±0.460), SCP3 protein (2.250±0.306, 7.058±0.521, 8.654±0.804), γH2AX protein (4.304±0.433, 5.713±0.339, 9.268±0.545), Ddx4 mRNA (1.374±0.145, 2.846±0.194, 4.021±0.154), Tp2 mRNA (1.358±0.130, 3.623±0.326, 5.811±0.390) and Prm1 mRNA (1.326±0.162, 3.487±0.237, 4.666±0.307) in 0.1µg/mL, 1µg/mL, 10µg/mL icariin experimental groups were all lower than that of VASA protein (10.560±0.413), SCP3 protein (13.804±0.642), γH2AX protein (11.874±0.464), Ddx4 mRNA (6.4005±0.361), Tp2 mRNA (7.314±0.256) and Prm1 mRNA (7.334±0.390) in 100µg/mL icariin experimental group. CONCLUSIONS: Icariin can promote the transformation of mouse induced pluripotent stem cells into sperm cells in vitro, and it is concentration-dependent manner in a certain concentration range.

Relationship between serum concentration and clinical response of quetiapine in adolescents and adults with bipolar disorders in acute stage: a prospective observational study.

BACKGROUND: It is found that there are great differences in the efficacy of quetiapine at the same dose in many patients with bipolar disorders. Therefore, therapeutic drug monitoring (TDM) is a valuable tool for guiding treatment with quetiapine. The aims of this study were to assess the relationship between serum concentration and clinical response of quetiapine in adolescents and adults with bipolar disorders in acute stage. METHODS: The study design was prospective and observational. Within the naturalistic setting of a routine TDM service at the First Affiliated Hospital, Zhejiang University School of Medicine. Psychiatric symptoms were assessed using the HAMD (Hamilton Depression Scale), YRMS (Young manic rating scale) and CUDOS-M (Clinically Useful Depression Outcome Scale-Mixed Subscale). The decline of HAMD and YMRS scores was were used to assess clinical outcome of bipolar disorders respectively. RESULTS: 169 inpatients (23.7 % male, 76.3 % female) were enrolled in the study. We found that there was a strong correlation between quetiapine serum concentrations and clinical outcomes (rs = 0.702, p < 0.001). While, quetiapine daily dose was not correlated with clinical outcome. We found that when the quetiapine serum level is >146.85 ng/ml in depression episodes patients could obtain a satisfactory treatment effect after 2 weeks of hospitalization. CONCLUSIONS: We found a significant positive relationship between serum concentration and clinical outcome, and also determined the serum concentration of quetiapine for the treatment of bipolar depression.

Repetitive transcranial magnetic stimulation in combination with citalopram in young patients with first-episode major depressive disorder: a double-blind, randomized, sham-controlled trial.

OBJECTIVES: To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) started with citalopram in first-episode young major depressive patients. METHODS: In a 2-week double-blind study with a 2-week extended antidepressant phase, 60 first-episode young major depressive patients were randomly assigned to citalopram in combination with 2 weeks of either active or sham rTMS treatment. During the following 2 weeks, the patients continued only the citalopram treatment. The 17-item Hamilton depression rating scale (HAMD-17) and Montgomery-Asberg depression rating scale (MADRS) were used to assess the severity of depression. Moreover, the Wisconsin Card Sorting Test (WCST), Trail-Making Test (TMT), and Stroop Color-Word Test (SCWT) were used to assess executive function. RESULTS: (1) There was a significantly greater number of early improvers (a reduction of HAMD-17 score ≥ 20% within the first 2 weeks) observed in the active rTMS group compared to the sham group (57% vs. 29%, χ(2)=4.667, p=0.031). (2) There was no significant difference observed in responder rates (46% vs. 36%, χ(2)=0.295, p=0.586) or in remission rates (39% vs. 29%, χ(2)=0.319, p=0.572) between the two groups at 4 weeks. (3) There was a significant difference seen in both HAMD-17 and MADRS scores between the two groups at 2 and 4 weeks. The active rTMS group showed a significantly faster score reduction compared to the sham group at 2 weeks (HAMD-17, t=13.444, p=0.001; MADRS, t=30.123, p=0.000), which was maintained at 4 weeks on both scales (HAMD-17, t=46.915, p=0.000; MADRS, t=39.996, p=0.000). (4) The patients did not deteriorate in executive performance, and even improved in categories on WCST and completed TMT faster in the active group. CONCLUSIONS: RTMS accelerated the rapidity of the antidepressant response in first-episode young depressive patients. Our results call for future rTMS studies with larger sample sizes, high intensity of stimuli, and longer duration to draw more definitive conclusions.

Co-melting technology in resource recycling of sludge derived from stone processing.

Stone processing sludge (SPS) is a by-product of stone-processing wastewater treatment; it is suitable for use as a raw material for making artificial lightweight aggregates (ALWAs). In this study, boric acid was utilized as a flux to lower sintering temperature. The formation of the viscous glassy phase was observed by DTA curve and changes in XRD patterns. Experiments were conducted to find the optimal combination of sintering temperature, sintering time, and boric acid dosage to produce an ALWA of favorable characteristics in terms of water absorption, bulk density, apparent porosity, compressive strength and weight loss to satisfy Taiwan's regulatory requirements for construction and insulation materials. Optimal results gave a sintering temperature of 850 degrees C for 15 min at a boric acid dosage of 15% by weight of SPS. Results for ALWA favorable characteristics were: 0.21% (water absorption), 0.35% (apparent porosity), 1.67 g/cm3 (bulk density), 66.94 MPa (compressive strength), and less than 0.1% (weight loss).

Resource recycling through artificial lightweight aggregates from sewage sludge and derived ash using boric acid flux to lower co-melting temperature.

This study focuses on artificial lightweight aggregates (ALWAs) formed from sewage sludge and ash at lowered co-melting temperatures using boric acid as the fluxing agent. The weight percentages of boric acid in the conditioned mixtures of sludge and ash were 13% and 22%, respectively. The ALWA derived from sewage sludge was synthesized under the following conditions: preheating at 400 degrees C 0.5 hr and a sintering temperature of 850 degrees C 1 hr. The analytical results of water adsorption, bulk density, apparent porosity, and compressive strength were 3.88%, 1.05 g/cm3, 3.93%, and 29.7 MPa, respectively. Scanning electron microscope (SEM) images of the ALWA show that the trends in water adsorption and apparent porosity were opposite to those of bulk density. This was due to the inner pores being sealed off by lower-melting-point material at the aggregates'surface. In the case of ash-derived aggregates, water adsorption, bulk density, apparent porosity, and compressive strength were 0.82%, 0.91 g/cm3, 0.82%, and 28.0 MPa, respectively. Both the sludge- and ash-derived aggregates meet the legal standards for ignition loss and soundness in Taiwan for construction or heat insulation materials.

Military traumatic brain injury: a challenge straddling neurology and psychiatry.

Military psychiatry, a new subcategory of psychiatry, has become an invaluable, intangible effect of the war. In this review, we begin by examining related military research, summarizing the related epidemiological data, neuropathology, and the research achievements of diagnosis and treatment technology, and discussing its comorbidity and sequelae. To date, advances in neuroimaging and molecular biology have greatly boosted the studies on military traumatic brain injury (TBI). In particular, in terms of pathophysiological mechanisms, several preclinical studies have identified abnormal protein accumulation, blood-brain barrier damage, and brain metabolism abnormalities involved in the development of TBI. As an important concept in the field of psychiatry, TBI is based on organic injury, which is largely different from many other mental disorders. Therefore, military TBI is both neuropathic and psychopathic, and is an emerging challenge at the intersection of neurology and psychiatry.

Different oxytocin and corticotropin-releasing hormone system changes in bipolar disorder and major depressive disorder patients.

BACKGROUND: Oxytocin (OXT) and corticotropin-releasing hormone (CRH) are both produced in hypothalamic paraventricular nucleus (PVN). Central CRH may cause depression-like symptoms, while peripheral higher OXT plasma levels were proposed to be a trait marker for bipolar disorder (BD). We aimed to investigate differential OXT and CRH expression in the PVN and their receptors in prefrontal cortex of major depressive disorder (MDD) and BD patients. In addition, we investigated mood-related changes by stimulating PVN-OXT in mice. METHODS: Quantitative immunocytochemistry and in situ hybridization were performed in the PVN for OXT and CRH on 6 BD and 6 BD-controls, 9 MDD and 9 MDD-controls. mRNA expressions of their receptors (OXTR, CRHR1 and CRHR2) were determined in anterior cingulate cortex and dorsolateral prefrontal cortex (DLPFC) of 30 BD and 34 BD-controls, and 24 MDD and 12 MDD-controls. PVN of 41 OXT-cre mice was short- or long-term activated by chemogenetics, and mood-related behavior was compared with 26 controls. FINDINGS: Significantly increased OXT-immunoreactivity (ir), OXT-mRNA in PVN and increased OXTR-mRNA in DLPFC, together with increased ratios of OXT-ir/CRH-ir and OXTR-mRNA/CRHR-mRNA were observed in BD, at least in male BD patients, but not in MDD patients. PVN-OXT stimulation induced depression-like behaviors in male mice, and mixed depression/mania-like behaviors in female mice in a time-dependent way. INTERPRETATION: Increased PVN-OXT and DLPFC-OXTR expression are characteristic for BD, at least for male BD patients. Stimulation of PVN-OXT neurons induced mood changes in mice, in a pattern different from BD. FUNDING: National Natural Science Foundation of China (81971268, 82101592).

[Repetitive transcranial magnetic stimulation combined with antidepressant medication in treatment of first-episode patients with major depression].

OBJECTIVE: To assess the early therapeutic and cognitive effect of repetitive transcranial magnetic stimulation (rTMS) combined with antidepressant medication in treatment of first-episode patients with major depression. METHODS: Sixty first-episode depressed inpatients aged 18-45 y, who met the DSM-IV clinical criteria for major depressive episode were randomly assigned to citalopram treatment (20 mg/d) in combination with a two-week period of either rTMS (study group)or sham procedure (control group) on left dorsal-lateral prefrontal cortex (10 Hz, 90% motor threshold). The Hamilton Depression Rating Scale (HAMD) was used to assess the severity of depression. The Wisconsin Card Sorting Test (WCST) and Continuous Performance Test (CPT) were used to assess cognitive function of depression. RESULT: The response rate was significantly greater in the study group compared to the control group after treatment (57% compared with 29%,P<0.05). The HAMD scores significantly declined after treatment in two groups, and the study group showed lower scores compared to the control group after 2 weeks (P<0.01). Neuropsychological assessments showed that there was no significant difference between the two groups except for the significant improvement in the categories on WCST in study group compared to the baseline (P<0.05) and the control group (P<0.05)after 2 weeks treatment. No serious event occurred in the patients during the rTMS study. CONCLUSION: 10 Hz rTMS enhances early effects of citalopram and improves cognitive function in first-episode major depressive patients.

Change in symptom clusters perioperatively in patients with lung cancer.

PURPOSE: To describe the trajectory, number, and types of symptom clusters at three time points (i.e., day of admission [T1], 2-4 days postoperatively [T2], and 1 month postoperatively [T3]) using ratings of symptom occurrence and severity and to identify the changes in these symptom clusters over time in patients with lung cancer. METHODS: We analysed the data of 217 lung cancer patients who received surgical treatment at a tertiary hospital affiliated to Anhui Medical University, in Hefei City, China. The occurrence and severity of 19 symptoms at all points of measurement were measured using the general and lung cancer modules of the M.D. Anderson Symptom Inventory. Exploratory factor analysis was performed to extract the symptom clusters. RESULTS: Seven symptom clusters were identified across symptom dimensions. However, only three of them (i.e., lung cancer specific, sleep disturbance, and nervous system) were relatively stable across dimensions and time. Two symptom clusters varied over time but not with dimensions (nutritional and gastrointestinal). The other two symptom clusters (psychological and respiratory) differed in terms of time and dimensions. CONCLUSIONS: Findings may provide insights into the seven identified clusters and overall stability of three symptom clusters in lung cancer patients perioperatively.

Psychometric properties of the Clinically Useful Depression Outcome Scale supplemented with DSM-5 Mixed subtype questionnaire in Chinese patients with mood disorders.

BACKGROUND: With the modification of DSM-5 mixed features specifier, a brief scale to screen mixed features in patients with mood disorders is needed in clinical practice. This study aimed to explore the psychometric properties of the Chinese version of the Clinically Useful Depression Outcome Scale supplemented with DSM-5 Mixed subtype (CUDOS-M-C) for the Chinese patients with mood disorders. METHODS: Overall, 300 patients with major depressive episode were recruited. All participants were assessed using CUDOS-M-C, Young Mania Rating Scale, Hamilton Anxiety Scale and Montgomery-Asberg Depression Rating Scale. The receiver operating characteristic (ROC) curve analysis was used to calculate the optimal cut-off values of CUDOS-M-C score. The reliability and validity of CUDOS-M-C were examined using Cronbach's alpha, intraclass correlation coefficient (ICC) and principal component analysis (PCA). RESULTS: The results of PCA indicated two-factor structure as the best solution for CUDOS-M-C, which explained 54.82% of cumulative variance. The Cronbach's alpha was 0.892 and the ICC was 0.853. The area under the ROC curve of the CUDOS-M-C for participants with mixed depression was 0.927 (p<0.001) and the suitable cut-off value was 8, with a sensitivity of 91.6% and specificity of 79.9%. LIMITATIONS: Most of the patients were recruited from eastern China and further research with larger sample is warranted. And this study did not perform confirmatory factor analysis to identify the generalization of factor structure of CUDOS-M-C. Besides, the study performed the test-retest reliability of CUDOS-M-C and further analysis is needed to ascertain the patient's post-treatment changes. CONCLUSION: The CUDOS-M-C demonstrated to have satisfactory psychometric properties as a self-report scale, and could be applied to screen patients with mixed depression in clinical practice.

Discovery of new genetic loci for male sexual orientation in Han population.

Epidemiological studies have demonstrated that the genetic factors partly influence the development of same-sex sexual behavior, but most genetic studies have focused on people of primarily European ancestry, potentially missing important biological insights. Here, we performed a two-stage genome-wide association study (GWAS) with a total sample of 1478 homosexual males and 3313 heterosexual males in Han Chinese populations and identified two genetic loci (rs17320865, Xq27.3, FMR1NB, Pmeta = 8.36 × 10-8, OR = 1.29; rs7259428, 19q12, ZNF536, Pmeta = 7.58 × 10-8, OR = 0.75) showing consistent association with male sexual orientation. A fixed-effect meta-analysis including individuals of Han Chinese (n = 4791) and European ancestries (n = 408,995) revealed 3 genome-wide significant loci of same-sex sexual behavior (rs9677294, 2p22.1, SLC8A1, Pmeta = 1.95 × 10-8; rs2414487, 15q21.3, LOC145783, Pmeta = 4.53 × 10-9; rs2106525, 7q31.1, MDFIC, Pmeta = 6.24 × 10-9). These findings may provide new insights into the genetic basis of male sexual orientation from a wider population scope. Furthermore, we defined the average ZNF536-immunoreactivity (ZNF536-ir) concentration in the suprachiasmatic nucleus (SCN) as lower in homosexual individuals than in heterosexual individuals (0.011 ± 0.001 vs 0.021 ± 0.004, P = 0.013) in a postmortem study. In addition, compared with heterosexuals, the percentage of ZNF536 stained area in the SCN was also smaller in the homosexuals (0.075 ± 0.040 vs 0.137 ± 0.103, P = 0.043). More homosexual preference was observed in FMR1NB-knockout mice and we also found significant differences in the expression of serotonin, dopamine, and inflammation pathways that were reported to be related to sexual orientation when comparing CRISPR-mediated FMR1NB knockout mice to matched wild-type target C57 male mice.

Interpersonal psychotherapy-based psychological intervention for patient suffering from COVID-19: A case report.

BACKGROUND: Novel coronavirus disease 2019 (COVID-19) was first found in Wuhan, China, and it has rapidly spread worldwide since the end of 2019. There is an urgent need to treat the physical and psychological aspects of COVID-19. Interpersonal psychotherapy (IPT)-based psychological intervention is an evidence-based therapy for depression and post-traumatic stress disorder. CASE SUMMARY: This report describes a case of COVID-19 in a patient who transmitted the disease to his entire family. The patient received four sessions of IPT-based psychological intervention. We used the Hamilton Rating Scale for Depression and Patient Health Questionnaire to measure depression level, and the Hamilton Anxiety Scale and Generalized Anxiety Disorder to measure anxiety among the patients. CONCLUSION: This case shows that IPT-based therapy can reduce COVID-19 patient depression and anxiety and the advantage of IPT-based therapy.

Dialectical behavior therapy-based psychological intervention for woman in late pregnancy and early postpartum suffering from COVID-19: a case report.

At the end of 2019, a new form of pneumonia disease known as the corona virus disease 2019 (COVID-19) rapidly spread throughout most provinces of China, and the total global number of COVID-19 cases has surpassed 500 000 by Mar. 27, 2020 (WHO, 2020). On Jan. 30, 2020, the World Health Organization (WHO) declared COVID-19 a global health emergency (WHO, 2020). COVID-19 causes most damage to the respiratory system, leading to pneumonia or breathing difficulties. The confirmed case fatality risk (cCFR) was estimated to be 5% to 8% (Jung et al., 2020). Besides physical pain, COVID-19 also induces psychological distress, with depression, anxiety, and stress affecting the general population, quarantined population, medical staff, and patients at different levels (Kang et al., 2020; Xiang et al., 2020). Previous research on patients in isolation wards highlighted the risk of depressed mood, fear, loneliness, frustration, excessive worries, and insomnia (Abad et al., 2010).

Efficacy of internet-based integrated intervention on depression and anxiety symptoms in patients with COVID-19.

Public health crises, such as the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) since Dec. 2019, are widely acknowledged as severe traumatic events that impose threats not only because of physical concerns but also because of the psychological distress of infected patients. We designed an internet-based integrated intervention and evaluated its efficacy on depression and anxiety symptoms in patients infected by SARS-CoV-2.
