Abstract
BACKGROUND Patients with major depressive disorder (MDD) are at high risk for suicide. As the worst outcome of MDD and common self-concealment in patients with suicide risk, studies of biomarkers may provide useful tools for suicide prevention and treatment. METHODS This study recruited 168 patients with MDD from the Objective Diagnostic Markers and Personalized Intervention in MDD patients (ODMPIM), including 50 patients with suicide risk. Based on previous evidence and hypothesis, 23 targeted serum biomarkers involving immune-inflammation, neurotrophins, hypothalamic-pituitary-adrenal (HPA) axis and metabolism, were measured. We used path analysis and principal components analysis (PCA) to clarify the associations among serum biomarkers, childhood adversities, adulthood life events, severity of depression and suicide risk. RESULTS We identified that patients with suicide risk had a higher level of inflammatory markers in serum than patients without suicide risk (P < 0.001), especially chemokine (C-X-C motif) ligand 1 (CXCL-1). After using the Bonferroni correction, there were no differences in biomarkers related to neurotrophins, HPA-axis and metabolism. In addition, a higher proportion of patients with suicide risk had adulthood adversity (assessed by Life Events Scale) (P = 0.003). Intriguingly, path analysis demonstrated that the association between adulthood adversity and suicide risk mainly depended on severity of depression and inflammatory index. CONCLUSION This study highlights the possible role of inflammation involved in suicide risk of MDD patients. Inflammatory markers have the potential for early identification and then reducing suicidal behaviors or becoming novel treatment targets in suicide risk management.

Abstract
Objective: To investigate the protective mechanism of ginsenoside Rb-1 on the brain in a rat model of Alzheimer's disease. Methods: Fifty-six male Sprague-Dawley rats were randomly divided into control group, model group, low-dose Rb-1 group (Rb-1: 25 mg•kg(-1)•d(-1)) and high-dose Rb-1 group (Rb-1:50 mg•kg(-1)•d(-1)). Morris water maze was designed to observe the changes of learning and memory ability in rats. Flow cytometry was used to detect the apoptosis of hippocampal neurons. Immunohistochemistry and Western blot were employed to detect the expression levels of apoptosis-related genes (p53, Bax, cytochrome C (Cyto C), Caspase-3 and caspase-9) and anti-oxidative stress-associated genes (nuclear Factor-E2-related factor 2 (Nrf2), kelch-like ECH-associated protein 1 (keap-1), heme oxygenase 1(HO-1) and NADPH quinone dehydrogenase 1 (NQO1)).The activities of catalase (CAT), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) were detected by relevant kits. ANOVA and Tukey-Kramer test were used for statistical analysis. Results: The learning and memory ability of rats in the model group was lower than that of the control group (P<0.01).The learning and memory ability of rats in the high-dose Rb-1 treatment group was significantly higher than that of the model group [(80±8) s vs (100±11) s, t=5.390, P<0.01]. The expression levels of apoptosis-related genes (p53, Bax, Cyto C, caspase-3 and caspase-9) in the model group were significantly higher than those in the control group (P<0.01), while the expression levels of these genes in low-dose and high-dose Rb-1 groups were significantly lower than those of the model group (P<0.01). The expression levels of Nrf2, HO-1 and NQO1 genes in the model group were significantly lower than those in the control group (P<0.05), while the expression of these genes in low-dose and high-dose Rb-1 groupswere significantly higher than those of the model group (P<0.01). The activities of CAT, GSH-Px and SOD in the model group were lower than those in the control group (P<0.01), however the activities of CAT, GSH-Px and SOD in low-dose and high-dose Rb-1 groups were higher than those of model group (P<0.05). Conclusions: Both low-dose and high-dose Rb-1 have protective effect on memory and cognitive function of Alzheimer's disease rats by reducing the damage and apoptosis of hippocampal neurons, down-regulating the expression levels of p53, Bax, Cyto C, caspase-3 and caspase-9, up-regulating the expression of Nrf2, HO-1 and NQO1 genes, and increasing the activities of CAT, GSH-Px and SOD. Moreover, the protective effect of Rb-1 on rat brain may be dose-dependent.

Abstract
Neuropsychiatric disorders represent a set of severe and complex mental illnesses, and the exact etiologies of which are unknown. It has been well documented that impairments in the early development of the brain contribute to the pathogenesis of many neuropsychiatric disorders. Currently, the diagnosis of neuropsychiatric disorders largely relies on subjective cognitive assessment, because there are no widely accepted biochemical or genetic biomarkers for diagnosing mental illness. Circular RNAs (circRNAs) are a novel class of endogenous non-coding RNA (ncRNA) with a closed-loop structure. In recent years, there have been tremendous advances in our understanding of the expression profiles and biological roles of circRNAs. In the brain, circRNAs are particularly enriched and are expressed more abundantly in contrast to linear counterpart transcripts. They are highly active at neuronal synapses. These features make circRNAs uniquely crucial for understanding brain health, disease, and neuropsychiatric disorders. This review focuses on the role of circRNAs in early brain development and other brain-related processes that have been associated with the development of neuropsychiatric disorders. In addition, we discuss the potential for blood or cerebrospinal fluid circRNAs to be used as novel biomarkers in the early diagnosis of neuropsychiatric disorders. The findings reviewed here may provide new insight into the pathological mechanisms underlying the onset and progression of neuropsychiatric disorders.

Abstract
Objective: To explore the feasibility of gender assignment in 46,XY disorders of sex development (DSD) with severe undermasculinisation mainly based on molecular diagnosis. Methods: A retrospective study of 45 patients of 46, XY DSD with severe undermasculinisation were admitted between November 2015 and October 2018 at Children's Hospital, Zhejiang University School of Medicine. The initial social gender were all female, of whom the external genital manifestations were Prader 0 to 2; the degree of masculinity was scored using external masculinisation score (EMS); the position and development of the gonads were examined by ultrasound, cystoscopy and laparoscopy, also including assessing the development of the Wolffian tube and the Müllerian tube. The level and ratio of testosterone to dihydrotestosterone before and after hCG stimulation were evaluated for the function of Leydig cell and 5α-reductase-2. Gender role scales and sandbox games were used to assess gender role behavior. Genital sensitivity to androgen stimulation was assessed; A panel including 163 genes related to gender development were determined by second-generation sequencing in all 45 patients. Finally, a multidisciplinary team (MDT) makes a gender assignment after a comprehensive analysis mainly based on the molecular etiological diagnosis. Results: Thirty-nine out of 45 patients (87%) had an identifiable genetic etiology, and the remaining 6 (13%) were negative for genetic testing. Forty-five patients had EMS less than or equal to 3 points. Sexual psychological assessment was performed in 39 patients, with male dominance in 24 (62%) and female dominance in 15 (38%). The gender assignment was 23 cases (51%) for male and 19 cases (42%) for female, and 3 cases (7%) were not completely determined. Conclusions: Molecular diagnosis provides a strong basis for appropriate gender assignment of 46, XY DSD children with severe undermasculinisation. Based on molecular diagnosis, each DSD should be analyzed by professional MDT to analyze the clinical symptoms/signs, gonadal development, gonad tumor risk, external genital morphology, sexual psychological assessment, potential fertility opportunities, parental views, Social and cultural factors, etc. make appropriate gender assignment.

Abstract
One patient with chronic refractory wound in right lower leg was admitted to our department in June 2017, which experienced repeated ulceration for 4 years. On 4 days post admission, two bamboo sticks were taken out from the deep muscle of the right lower leg. The wound was repaired by perforator flap of posterior tibial artery in the right lower leg. The donor site was covered with split-thickness skin in the upper leg of the same side. On 7 days post operation, the flap and skin graft survived. During follow-up of 12 months, the flap had good appearance. This case suggests that the first thing for the treatment of chronic refractory wound is to find out the cause of wound.

Abstract
Objective: To investigate the effect of preventing perivascular adhesion with topical application of sodium hyaluronate on intimal hyperplasia of the vein grafts in rabbits. Methods: Twenty-four male New Zealand white rabbits, aged 5 months, were randomly divided into 2 groups: Group A and B (n=12 rabbits per group). Artery defect model was established by cutting about 1 cm artery from the middle part of the dissociated left common carotid artery. A section about 3 cm was cut from the right external jugular vein, and the harvested vein was inverted and end-to-end anastomosed to the artery defect. After anastomosis, the adventitia and two anastomosis of the grafted veins in group A was applied 0.2 ml sodium hyaluronate locally to, and corresponding site in Group B was served as a control, but with the sterile normal saline. The grafted veins were obtained 1, 2 and 4 weeks after operation, HE staining and Masson staining were preformed for histological changes of grafted vein wall, proliferating cell nuclear antigen (PCNA) and platelet-derived growth factor (PDGF) immunohistochemistry staining were conducted for proliferation and expression and distribution of PDGF of the grafted vein. Results: The macroscopic and histological observation showed that the perivascular adhesions in Group A were looser when compared with those in Group B. The thickness of the intima, the degree of intima hyperplasia of 2 groups at different time points were as follows: at 1 week after operation, group A[(25.5±3.9) μm, (1.2±0.1) ]and group B[(26.2±4.2)μm, (1.2±0.1)]; at 2 weeks after operation, group A[(44.3±2.5)μm, (1.2±0.1)]and group B[(51.0±3.8)μm, (1.4±0.0)]; at 4 weeks after operation, group A[(69.9±6.8)μm, (1.5±0.1)] and group B[(84.4±6.4)μm, (1.7±0.1)]. Group A was inferior to group B in terms of the above three parameters 2 and 4weeks after operation (P<0.05). Cell proliferation index of intima and that of media were as follows: at 1 week after operation, group A (7.4±2.2), (21.5±3.2) and group B (11.5±2.0), (28.6±4.5); at 2 weeks, group A (20.0±3.2), (35.8±3.4) and group B (26.8±4.1), ( 42.6±4.2); at 4 weeks, group A (11.4±2.0), (22.1±2.7) and group B (15.5±2.4, 28.6±3.9). Group A was inferior to group B in terms of cell proliferation index of intima and media 1, 2 and 4 weeks after operation (P<0.05). The percentage of PDGF-positive cells of intima, media and adventitia was as follows: at 1 week after operation, group A (7.7±1.6), (19.6±3.7), (2.5±1.5) and group B (7.6±2.4), (20.6±4.4), (10.3±2.3); at 2 weeks after operation, group A (11.4±2.6), (19.8±3.1), (12.9±3.3) and group B (19.5±3.5), ( 30.6±5.2), (30.5±5.8); at 4 weeks after operation, group A (6.2±1.9), ( 11.1±2.8), (10.2±2.4) and group B (10.5±2.0), (18.6±3.2), (26.5±3.8). Group A was inferior to group B in terms of the percentage of PDGF-positive cells of intima, media and adventitia 2 and 4 weeks after operation (P<0.05) and Group A was inferior to group B that of adventitia 1 week after operation (P<0.05). Conclusion: Preventing perivascular adhesion with topical application of sodium hyaluronate can inhibit intimal hyperplasia.

Abstract
Background: This study aimed to observe the differences in brain gray matter volume in drug-naive female patients after the first episode of major depression with and without stressful life events (SLEs) before the onset of depression. Methods: Forty-three drug-naive female patients voluntarily participated in the present study after the first major depressive episode. The life event scale was used to evaluate the severity of the impact of SLEs during 6 months before the onset of the major depressive episode. High-field magnetic resonance imaging (MRI) scans were obtained, and the VBM and SPM8 software process were used to process and analyze the MRI. Results: Compared to that in patients without SLEs, the volume of brain gray matter was lower in the bilateral temporal lobe, right occipital lobe, and right limbic lobe in the SLE group. However, the gray matter volume did not differ significantly between the two groups after the application of false discovery rate (FDR) correction. Conclusions: Although the results of the present study suggest the absence of significant differences in brain gray matter volume between female drug-naive patients after the first episode of major depression with and without SLEs after FDR correction, the study provides useful information for exploring the definitive role of stress in the onset of depression.

Abstract
OBJECTIVE To study the influence of bone marrow mesenchymal stem cells (MSCs) transplantation on hypoxic pulmonary hypertension (HPH) in rats. METHODS SD rats MSCs were separated, cultivated, identified and labeled by the green fluorescence protein (GFP) gene virus and transplanted in vitro. Healthy male SD rats were randomly divided into four groups: Normal control group (NC group) and HPH group (eight rats respectively), HPH+ MSCs transplantation group and HPH+ VEGF+ MSCs transplantation group (twenty-four respectively). The test employed atmospheric intermittent low oxygen method to establish the rat model of pulmonary hypertension and stem cells were transferred and transplanted. The rats' mean pulmonary artery pressure (mPAP) was observed; right ventricular hypertrophy index (RVHI) was calculated; the morphological change of lung small artery in various groups of rats was observed under the microscope; the distribution of lung small artery and adenovirus transfection fluorescently labeled MSCs was observed under a fluorescent microscope after 7, 14 and 28 days when stem cell was transplanted. RESULTS For NC group, the mPAP (mmHg) was 15.5 +/- 1.5 after twenty-eight days while the mPAPs for HPH , MSCs and MSCs+ VEGF were 26.1 +/- 1.9, 21.6 +/- 2.7 and 20.1 +/- 2.9 respectively which were apparently higher than that of NC group (P < 0.01) and compared with HPH group (P < 0.01), which declined clearly. There was no significant difference between MSCs and MSCs+ VEGF. After twenty-eight days, RVHI for NC group was 0.28 +/- 0.02 while the RVHI for HPH, MSCs and MSCs + VEGF were 0.43 +/- 0.07, 0.34 +/- 0.03 and 0.35 +/- 0.01 respectively which was apparently higher than that of NC group (P < 0.01) but which was clearly lower than that of MSCs and MSCs+ VEGF (P < 0.05) and there was no significant difference between MSCs and MSCs + VEGF. For HPH group, pulmonary arteriole wall became apparently thicker, the lumen became significantly narrow and nearly obstructed after twenty-eight days, the endothelial cells were incomplete; compared with HPH group, pulmonary arteriole wall of MSCs group became thin, the lumen was smooth and the completeness of endothelial cells was improved. Whereas for MSCs and MSCs + VEGF, these changes were not significantly clear. CONCLUSION After MSCs transplantation, mPAP and RVHI decline sharply and lung small artery remodeling is improved which partially reverses HPH process; there is no significant difference between VEGF together with MSCs transplantation group and pure MSCs.

Abstract
OBJECTIVE To investigate septal cartilage compressive changes as a result of bilateral extended spreader grafts (ESGs), which are commonly used in rhinoplasty. The buckling, rupturing, or necrosis of the recipient site leads to nasal tip structural deformity. These pathologic changes associated with bilateral ESGs warrant the clinician's attention and in-depth basic and clinical research. METHODS The basic experimental study involves New Zealand rabbits, randomly assigned to groups A, B, C, and D, with group A as a reference. The right auricular cartilage was harvested and transplanted into a corresponding anatomic location of the left ear. The compressive effect was studied by gross observation and microscopic examination with hematoxylin-eosin staining after 3 months. In a clinical experiment, revision rhinoplasty surgical procedures were performed in 10 human patients 6 months to 1 year after placement of bilateral ESGs. The compressive changes of septal cartilages between the ESGs were observed intraoperatively. RESULTS In group A of the rabbits, no pathologic change was noted, but 2 cases of attenuation were observed in group B (33.3%), 6 cases of central fracture (100%) with 1 case of perforation (16.7%) in group C, and 6 cases of different degrees of defects in group D (100%). Clinical intraoperative observations revealed 1 case of defects and necrosis (10%), 4 cases of attenuations and cracks (40%), and 5 cases of attenuations (50%). CONCLUSIONS Septal cartilage compressive necrosis leading to structural damage by bilateral septal ESGs is a clinically significant complication of rhinoplasty. Owing to its affect on the viability of the original septal cartilages, we believe the unilateral ESG with columellar strut is preferred, especially in Asian patients.

Abstract
Attention deficit hyperactivity disorder (ADHD) is the most common childhood-onset behavioral. Boys are more often affected than girls. Family, twin and adoption studies have supported a strong genetic basis. The etiology of this disorder is not clear. Molecular genetic and pharmacological studies suggest the involvement of dopaminergic and noradrenergic neurotransmitter systems in ADHD, e.g , Several reports have found association between ADHD and the dopamine receptor gene DRD-4.the dopamine transporter gene DAT1, and the catechol-o-methyltransferase. Our previous studies showed an association between ADHD and the DXS7 locus, which is located in closely linked to the MAO gene, and MAOA gene on chromosome X. To test this hypothesis, we used the genome scan for a predisposing locus on chromosome X to ADHD. We used the tramsmission/disequilibrium test (TDT) to test for linkage between a VNTR polymorphism at the 48 markers of chromosome X and DSM-III-R oliagnosed ADHD in 84 nuclear families of the Chinese population. The TDT analysis revealed linkage between ADHD and the DXS1214(TDT: Chi2=18.1, df=7, P<0.01), DXS8102(TDT: Chi2=7.9, df=3, P<0.05), DXS1068(TDT: Chi2=21.9, df=9, P<0.01), DXS8015(TDT: Chi2=14.6, df=7, P<0.05), DXS1059(TDT: Chi2=27.8, df=10, P<0.01) and DXS8088(TDT: Chi2=20.4, df=3, P<0.01).The data showed that susceptibility loci might reside in chromosome Xp11.4-Xp21 and Xq23 for ADHD.
