Abstract
Sex-specific neurobiological changes have been implicated in Major Depressive Disorder (MDD). Dysfunctions of the default mode network (DMN), salience network (SN) and frontoparietal network (FPN) are critical neural characteristics of MDD, however, the potential moderating role of sex on resting-state network dynamics in MDD has not been sufficiently evaluated. Thus, resting-state functional magnetic resonance imaging (fMRI) data were collected from 138 unmedicated patients with first-episode MDD (55 males) and 243 healthy controls (HCs; 106 males). Recurring functional network co-activation patterns (CAPs) were extracted, and time spent in each CAP (the total amount of volumes associated to a CAP), persistence (the average number of consecutive volumes linked to a CAP), and transitions across CAPs involving the SN, DMN and FPN were quantified. Relative to HCs, MDD patients exhibited greater persistence in a CAP involving activation of the DMN and deactivation of the FPN (DMN + FPN-). In addition, relative to the sex-matched HCs, the male MDD group spent more time in two CAPs involving the SN and DMN (i.e., DMN + SN- and DMN-SN + ) and transitioned more frequently from the DMN + FPN- CAP to the DMN + SN- CAP relative to the male HC group. Conversely, the female MDD group showed less persistence in the DMN + SN- CAP relative to the female HC group. Our findings highlight that the imbalance between SN and DMN could be a neurobiological marker supporting sex differences in MDD. Moreover, the dominance of the DMN accompanied by the deactivation of the FPN could be a sex-independent neurobiological correlate related to depression.

Abstract
Background: The most common types of wrist dislocation are trans-scaphoid lunate dislocation (TLD) and trans-scaphoid perilunate dislocation, in which the lunate and proximal scaphoid are dislocated through the midcarpal joint. There is another rare type of dislocation in which the proximal carpi are dislocated through the radiocarpal joint. The purpose of this study is to examine the clinical features of this type of dislocation. Methods: Six cases of the proximal carpal fracture dislocation via the radiocarpal joint were retrospectively reviewed. All patients underwent open reduction and internal fixation with the ligament reconstruction. A Mayo wrist score was assigned to each patient based on the assessment of pain, functional status, range of motion and grip strength at the last follow-up. Clinical subjective evaluation of function and pain was assessed using the patient-rated wrist evaluation (PRWE) method. Results: All patients were male and injured with a median age of 33.5 years. The median follow-up period was 10 months. There were three types of dislocations: Scaphoid fracture dislocation, TLD and scaphoid-lunate dislocation. All patients had satisfactory results with an average PRWE of 7.2 ± 4.7. The preoperative VAS was 6.7 ± 1.0 and the postoperative VAS was 0.7 ± 0.7 (p < 0.01). Postoperative grip strength accounted for 89.2% ± 9.8% of the contralateral side; the Mayo wrist score averaged 90.0 ± 6.5, with four patients obtaining excellent and two good results. Conclusions: Fracture dislocation of the proximal carpal bones through the radiocarpal joint is an independent type of wrist dislocation that tends to occur in young men with high-energy impact. The wrist is most often injured in a pronation hyperextension position. If treatment is timely and appropriate, the prognosis is quite good. Level of Evidence: Level IV (Therapeutic).

Abstract
BACKGROUND Distinguishing between trait- and state-like neural alternations in major depressive disorder (MDD) may advance our understanding of this recurring disorder. We aimed to investigate dynamic functional connectivity alternations in unmedicated individuals with current or past MDD using co-activation pattern analyses. METHODS Resting-state functional magnetic resonance imaging data were acquired from individuals with first-episode current MDD (cMDD, n = 50), remitted MDD (rMDD, n = 44), and healthy controls (HCs, n = 64). Using a data-driven consensus clustering technique, four whole-brain states of spatial co-activation were identified and associated metrics (dominance, entries, transition frequency) were analyzed with respect to clinical characteristics. RESULTS Relative to rMDD and HC, cMDD showed increased dominance and entries of state 1 (primarily involving default mode network (DMN)), and decreased dominance of state 4 (mostly involving frontal-parietal network (FPN)). Among cMDD, state 1 entries correlated positively with trait rumination. Conversely, relative to cMDD and HC, individuals with rMDD were characterized by increased state 4 entries. Relative to HC, both MDD groups showed increased state 4-to-1 (FPN to DMN) transition frequency but reduction in state 3 (spanning visual attention, somatosensory, limbic networks), with the former metric specifically related to trait rumination. LIMITATIONS Further confirmation with longitudinal studies are required. CONCLUSIONS Regardless of symptoms, MDD was characterized by increased FPN-to-DMN transitions and reduced dominance of a hybrid network. State-related effect emerged in regions critically implicated in repetitive introspection and cognitive control. Asymptomatic individuals with past MDD were uniquely linked to increased FPN entries. Our findings identify trait-like brain network dynamics that might increase vulnerability to future MDD.

Abstract
Background: Percutaneous fixation of scaphoid fractures need accurate guide pin insertion. The emergence of computer-assisted navigation and robotic surgery may provide a promising solution to this problem. Methods: This study presents the development of an automatic multi-degrees of freedom (DOF) surgical robot with computer-assisted navigation system, focusing on percutaneous scaphoid guide pin insertion. Using this device, along with a 3D fluoroscopy unit, we have conducted an experimental study on 10 cadavers for percutaneous scaphoid guide pin insertion to verify the feasibility and reliability of the system. Results: The mean operative duration was 29.1 (SD 4.3) minutes. The cadavers required no more than two attempts to achieve desired wire placement, with the mean positioning-error being 2.0 (SD 0.3) mm and the mean angle-deviation 3.6 (SD 0.7)°. Throughout the study, a mean of 2.2 full-cycle fluoroscopy attempts was required for each cadaver during surgery, and no preoperative CT scan was needed. Conclusions: The outcomes show that using the automatic surgical robot to perform the percutaneous scaphoid guide pin insertion is feasible and desired results can be achieved.

Abstract
Immune checkpoint inhibitors cause rare but potentially fatal neuromuscular complications, leading to a concern to use these agents in cancer patients with pre-existing autoimmune or inflammatory neuromuscular diseases. We report two such patients with paraneoplastic dermatomyositis and "seronegative" paraneoplastic demyelinating neuropathy, respectively, who have been successfully treated with immune checkpoint inhibitor monotherapy as well as maintenance intravenous immunoglobulin. While controlling the paraneoplastic or autoimmune neuromuscular diseases, the use of intravenous immunoglobulin did not compromise the anti-cancer effect of immune checkpoint inhibitor.

Abstract
Currently, the most widely used protocol for the transportation layer of computer networks for reliable transportation is the Transmission Control Protocol (TCP). However, TCP has some problems such as high handshake delay, head-of-line (HOL) blocking, and so on. To solve these problems, Google proposed the Quick User Datagram Protocol Internet Connection (QUIC) protocol, which supports 0-1 round-trip time (RTT) handshake, a congestion control algorithm configuration in user mode. So far, the QUIC protocol has been integrated with traditional congestion control algorithms, which are not efficient in numerous scenarios. To solve this problem, we propose an efficient congestion control mechanism on the basis of deep reinforcement learning (DRL), i.e., proximal bandwidth-delay quick optimization (PBQ) for QUIC, which combines traditional bottleneck bandwidth and round-trip propagation time (BBR) with proximal policy optimization (PPO). In PBQ, the PPO agent outputs the congestion window (CWnd) and improves itself according to network state, and the BBR specifies the pacing rate of the client. Then, we apply the presented PBQ to QUIC and form a new version of QUIC, i.e., PBQ-enhanced QUIC. The experimental results show that the proposed PBQ-enhanced QUIC achieves much better performance in both throughput and RTT than existing popular versions of QUIC, such as QUIC with Cubic and QUIC with BBR.

Abstract
BACKGROUND Major depressive disorder (MDD) is a highly prevalent mood disorder affecting more than 300 million people worldwide. Biased processing of negative information and neural hyper-responses to negative events are hallmarks of depression. This study combined cross-sectional and longitudinal experiments to explore both persistent and resolved neural hyper-responses to negative outcomes from risky decision making in patients with current MDD (cMDD) and remitted MDD (rMDD). METHODS A total of 264 subjects participated in the cross-sectional study, including 117 patients with medication-naïve, first-episode current depression; 45 patients with rMDD with only 1 episode of depression; and 102 healthy control subjects. Participants completed a modified balloon analog risk task during functional magnetic resonance imaging. In the longitudinal arm of the study, 42 patients with cMDD were followed and 26 patients with rMDD were studied again after 8 weeks of antidepressant treatment. RESULTS Patients with cMDD showed hyper-responses to loss outcomes in multiple limbic regions including the amygdala and ventral anterior cingulate cortex (vACC). Amygdala but not vACC hyperactivity correlated with depression scores in patients with cMDD. Furthermore, amygdala hyperactivity resolved while vACC hyperactivity persisted in patients with rMDD in both cross-sectional and longitudinal studies. CONCLUSIONS These findings provide consistent evidence supporting differential patterns of amygdala and vACC hyper-responses to negative outcomes during depression remission. Amygdala hyperactivity may be a symptomatic and state-dependent marker of depressive neural responses, while vACC hyperactivity may reflect a persistent and state-independent effect of depression on brain function. These findings offer new insights into the neural underpinnings of depression remission and prevention of depression recurrence.

Abstract
Abstract
Multi-fuel operation of the coal-fired boiler is considered as a promising option for boiler reformation to reduce carbon emissions while recycling solid waste. In this work, co-combustion characteristics of sugarcane bagasse, Nanning meager-lean coal and petroleum coke under different conditions were investigated in detail. And the interaction between raw materials was analyzed. Finally, the kinetic parameters were estimated by using the first-order response model. The results show that differences in petroleum coke content affect the appearance of weight loss peaks in the DTG curve. When the proportion of sugarcane bagasse is between 40 and 60%, the ignition and burnout characteristic indexes are particularly sensitive to variations in sugarcane bagasse content. Additionally, the interaction between the three raw materials is promoted as the proportion of petroleum coke is less than 40%. The kinetic analysis suggests that the increase of heating rate is conducive to the precipitation of volatiles, but there is an optimal heating rate for the fixed carbon combustion stage. The change of particle size combination has little effect on the activation energy of the volatile fraction combustion stage. This study provides a reference to ensure the stable and high-efficient operation of the coal-fired boilers during the multi-fuel combustion.

Abstract
PURPOSE To describe the clinical features, radiologic findings, differential diagnosis, and surgical treatment of a congenital flexion deformity of the middle, ring, and little fingers. The cause of the condition is the aberrant origin of the flexor digitorum profundus, leading to a congenital contracture of the ulnar digits. METHODS We reviewed 8 patients with congenital contracture of the ulnar digits. The mean age at the time of surgery was 14 years. An examination revealed a flexion contracture of the middle, ring, and small fingers. Plain radiographs, 3-dimensional computed tomography, magnetic resonance imaging, and ultrasound were used to characterize bony and soft tissue pathology. Surgical treatments included resection of the aberrant origin and a muscle-sliding procedure. RESULTS Bony prominence on the proximal ulna was seen in the plain radiographs and/or 3-dimensional computed tomography. A cord that extended from this bony prominence to the tendons of flexor digitorum profundus was revealed in the magnetic resonance imaging. The bony prominence and the cord were also seen using ultrasound. The median time of patient follow-up was 1.7 years. A simple resection of the tendinous origin only resulted in a release in 2 patients who were 4 years old. Older patients required a further muscle-sliding procedure. The average grip strength ratio on the contralateral side was 82%. CONCLUSIONS Congenital contracture of the ulnar digits is a new congenital flexion deformity involving the middle, ring, and small fingers. Bony prominence on the proximal ulna is the key finding for establishing its diagnosis and distinguishing it from an ischemic contracture. We recommend treating this surgically at 12 years of age or older after the phase of rapid growth of the extremities. We recommend the resection of the aberrant origin, combined with a muscle-sliding procedure, as the treatment of choice, even for young patients. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic V.

Abstract
BACKGROUND Emerging evidence has highlighted the moderating effect of childhood maltreatment (CM) in shaping neurobiological abnormalities in major depressive disorder (MDD). However, whether neural mechanisms underlying stress sensitivity in MDD are affected by the history of CM is unclear. METHODS Two hundred and thirteen medication-free female participants were recruited for a functional magnetic resonance imaging study assessing the effects of psychosocial stress on neural responses. The Montreal Imaging Stress Task was administrated to 44 female MDD patients with CM (MDD/CM), 32 female MDD patients without CM (MDD/noCM), 43 female healthy controls (HCs) with CM (HC/CM), and 94 female HCs without CM (HC/noCM). A CM (CM, noCM) × diagnosis (MDD, HC) whole-brain voxel-wise analysis was run to assess putative group differences in neural stress responses. RESULTS A significant CM × Diagnosis interaction emerged in the medial prefrontal cortex (mPFC). Bonferroni-corrected simple effects analysis clarified that (1) the MDD/CM group had less mPFC deactivation than the HC/CM group, (2) the MDD/noCM group exhibited greater mPFC deactivation than the HC/noCM group, and (3) the MDD/CM group exhibited less mPFC deactivation relative to the MDD/noCM group. In addition, the mPFC-seed psychophysiological interaction analysis revealed that individuals in the CM groups had significantly greater stress-related mPFC-left superior frontal gyrus and mPFC-right posterior cerebellum connectivity relative to the noCM groups. CONCLUSIONS Findings highlight distinct neural abnormalities in MDD depending on prior CM history, particularly potentiated stress-related mPFC recruitment among MDD individuals reporting CM. Moreover, CM history was generally associated with the disruption in functional connectivity centered on the mPFC.

Abstract
Congenital contractural arachnodactyly (CCA) is a rare autosomal dominant disorder of connective tissue characterized by crumpled ears, arachnodactyly, camptodactyly, large joint contracture, and kyphoscoliosis. The nature course of CCA has not been well-described. We aim to decipher the genetic and phenotypic spectrum of CCA. The cohort was enrolled in Beijing Jishuitan Hospital and Peking Union Medical College Hospital, Beijing, China, based on Deciphering disorders Involving Scoliosis and COmorbidities (DISCO) study (http://www.discostudy.org/). Exome sequencing was performed on patients’ blood DNA. A recent published CCA scoring system was validated in our cohort. Seven novel variants and three previously reported FBN2 variants were identified through exome sequencing. Two variants outside of the neonatal region of FBN2 gene were found. The phenotypes were comparable between patients in our cohort and previous literature, with arachnodactyly, camptodactyly and large joints contractures found in almost all patients. All patients eligible for analysis were successfully classified into likely CCA based on the CCA scoring system. Furthermore, we found a double disease-causing heterozygous variant of FBN2 and ANKRD11 in a patient with blended phenotypes consisting of CCA and KBG syndrome. The identification of seven novel variants broadens the mutational and phenotypic spectrum of CCA and may provide implications for genetic counseling and clinical management.

Abstract
Objective To explore the clinical characteristics, clinical classification, and treatment of wrist gouty arthritis. Methods The clinical data of 24 patients with wrist gouty arthritis and complete follow-up between April 2011 and August 2020 were retrospectively analyzed. There were 21 males and 3 females; the first onset age was 21-72 years, with a median age of 50 years. There were 15 cases of simple wrist joint disease, and 9 cases of other joints (hand, knee, ankle, metatarsophalangeal joint) involvement; 19 cases of wrist joint as the first site. Except for 1 patient with a medical history of 21 years, the time from onset to diagnosis in the remaining 23 patients was 7 days to 9 years, with a median time of 2 months. According to the clinical manifestations, imaging manifestations, lesion range, and intraoperative wrist arthroscopy manifestations of wrist gouty arthritis, they were classified into 5 types from mild to severe. Among the 24 patients, 13 were type Ⅰ, 2 were type ⅡA, 3 were type ⅡB, 2 were type ⅢA, 3 were type Ⅳ, and 1 was type Ⅴ. The time from first onset to diagnosis for type Ⅰ and type Ⅱ patients was (12.7±40.1) months, and for type Ⅲ-Ⅴ patients was (152.0± 88.5) months, the difference was significant ( t=-4.355, P=0.001). Thirteen patients with type Ⅰ received conservative treatment (including diet, exercise, lifestyle intervention, and medication), and 11 patients with type Ⅱ-Ⅴ received surgical treatment (including 1 case of arthroscopic synovial membrane and gout crystal clearing, 1 case of ligament repair, 5 cases of lesion debridement/artificial bone grafting and filling, 3 cases of wrist fusion, and 1 case of tophicectomy). Before and after treatment, the visual analogue scale (VAS) score was used to evaluate the improvement of wrist joint pain; and the range of motion of the wrist joint (including palmar flexion, dorsal extension, radial deviation, and ulnar deviation) was evaluated. Results Thirteen conservatively treated patients were followed up 10 months to9 years, with an average of 2.2 years. The VAS scores before treatment and at last follow-up were 6.8±0.7 and 2.9±0.9, respectively, and the difference was significant ( t=12.309, P=0.000). During follow-up, there was no wrist bone and wrist joint damage; wrist joint range of motion basically reached normal. At last follow-up, the wrist joint palmar flexion, dorsal extension, radial deviation, and ulnar deviation significantly improved when compared with the values before treatment ( P<0.05). Eleven surgically treated patients were followed up 5 months to 9 years, with an average of 4.9 years. The swelling and pain of all patients fully relieved, and the VAS scores were 7.3±0.8 before operation, 2.7±0.6 at 1 month after operation, and 2.5±0.6 at last follow-up, which significantly improved after operation ( P<0.05); there was no significant difference between 1 month after operation and last follow-up ( P>0.05). Excluded 3 patients who underwent wrist fusion, the other 8 patients had significantly improved wrist joint palmar flexion, dorsal extension, radial deviation, and ulnar deviation at last follow-up ( P<0.05). The patient's subjective satisfaction with the surgical results reached 100%. Conclusion A missed diagnosis or misdiagnosis of wrist gouty arthritis will greatly damage the wrist stability and functions. Early and proper interventions can effectively retard the progress of the disease. For the late-stage cases, a staged surgical protocol is recommended.

Abstract
It has been proposed recently that major depressive disorder (MDD) could represent an adaptation to conserve energy after the perceived loss of an investment in a vital source, such as group identity, personal assets, or relationships. Energy conserving behaviors associated with MDD may form a persistent marker in brain regions and networks involved in cognition and emotion regulation. In this study, we examined whether subcortical regions and volume-based structural covariance networks (SCNs) have state-independent alterations (trait markers). First-episode drug-naïve currently depressed (cMDD) patients (N = 131), remitted MDD (RD) patients (N = 67), and healthy controls (HCs, N = 235) underwent structural magnetic resonance imaging (MRI). Subcortical gray matter volumes (GMVs) were calculated in FreeSurfer software, and group differences in GMVs and SCN were analyzed. Compared to HCs, major findings were decreased GMVs of left pallidum and pulvinar anterior of thalamus in the cMDD and RD groups, indicative of a trait marker. Relative to HCs, subcortical SCNs of both cMDD and RD patients were found to have reduced small-world-ness and path length, which together may represent a trait-like topological feature of depression. In sum, the left pallidum, left pulvinar anterior of thalamus volumetric alterations may represent trait marker and reduced small-world-ness, path length may represent trait-like topological feature of MDD.

Abstract
Background: The etiology and natural history of Kienböck's disease remain unclear. Traditionally it has been defined as avascular necrosis of the lunate. The authors tried to demonstrate different tissue distribution, the area ratio of necrotic tissue and vessel counts inside the whole Kienböck lunate to reveal a dynamic process of the lunate collapse. Methods: Five lunates from patients with stage III Kienböck's disease and one cadaveric lunate not involved by Kienböck's disease were sampled. They were sectioned, H&E stained, and evaluated. The thickness of trabecular bone and the area of necrotic tissue were measured with Image-Pro Plus. The number of vessels was counted manually. Results: In the normal lunate, the bone trabeculae showed a uniform distribution with fatty marrow filled the interspace between the trabeculae. In the lunates with Kienböck disease, the trabeculae fracture and necrosis located in the central part with massive fibrous granular tissue proliferation. There were also some chondroid metaplasia at the palmar and dorsal ends. The trabeculae of the lunates of the Kienböck's disease [0.188 mm (0.153 mm, 0.236 mm)] was significantly thicker than the normal lunates [0.146 mm (0.124 mm, 0.164 mm)]. The necrosis was localized around the fracture sites instead of the whole lunate. The mean necrosis area only accounts for 16.3% ± 8.9% of the whole section. Such kind of focal necrosis is quite similar to those around the traumatic fracture ends of other bones. Even in stage III Kienböck lunates, the vessels are quite abundant (221 ± 42 in one sagittal section), while the vessels inside the normal lunate were 352 ± 28. Conclusions: There is neither massive nor obvious generalized avascular bone necrosis in our histopathology observations. The focal necrosis and vessel damage were more likely associated with the broken trabeculae inside the lunate. Based on our histopathology observations, we suggested that the progressive process of Kienböck's disease could be described as lunate nonunion advanced collapse instead of avascular necrosis.

Abstract
OBJECTIVE Diabetic nephropathy (DN) is one of the most representative diabetic microangiopathy complications. So far, there have been no satisfactory therapeutic strategies, and the injection of stem cells provides a target for DN therapy. PATIENTS AND METHODS Urine-derived stem cells (USCs) were obtained from 9 healthy men. 24 mice were randomly and equally divided into control group, DN model group, DN+hUSC group (treated with USCs for 3 times). Hematoxylin-eosin (HE) and Masson staining were used to detect histological changes of kidney injury. Creatinine and blood urea nitrogen (BUN) were measured to assess renal function. Besides, myofibroblast accumulation, macrophage infiltration, cell proliferation, and oxidative stress were detected by immunohistochemical analysis. RESULTS Compared with DN model group, DN+hUSC group showed lower function loss, cell infiltration, and oxidative stress, as well as less renal fibrosis, histological damage, and cell proliferation. CONCLUSIONS USC can alleviate inflammation and oxidative stress, reduce renal interstitial fibrosis, improve renal tissue structure and protect renal function through paracrine effect.

Abstract
BACKGROUND Childhood trauma is a major social public-health problem worldwide. Previous literature suggests childhood trauma is associated with the development of psychiatric disorders and maladaptive behaviours later in life, but little is known about the neural basis underlying these associations. OBJECTIVE The aim of the current study was to investigate intrinsic brain network alterations in non-clinical adults with childhood trauma. METHODS Resting-state functional magnetic resonance imaging (fMRI) data were collected from 65 non-clinical adults with moderate or severe childhood trauma (CT group), according to the international demarcation criteria of the Childhood Trauma Questionnaire (CTQ), and 73 socio-demographically matched non-clinical controls without childhood trauma (no-CT group). Independent component analysis (ICA) was used to extract subnetworks of the default mode network (DMN), salience network (SN), and central executive network (CEN). RESULTS ICA revealed that the CT group had increased FC of the left medial prefrontal cortex (mPFC) in the anterior DMN (aDMN), increased functional connectivity (FC) of the left anterior insula in the SN, and decreased FC of the inferior parietal gyrus of the right CEN (rCEN). Compared to the controls, the CT group had decreased inter-network FCs between the SN and posterior DMN (pDMN), as well as between the pDMN and rCEN. CONCLUSIONS Impaired FC within the three key brain networks, decreased inter-FC between SN and rCEN, and decreased inter-FC between pDMN and rCEN may reflect biomarkers of childhood trauma.

Abstract
PURPOSE To assess the longitudinal associations between maternal total bile acid (TBA) levels during early mid-pregnancy and the subsequent risk of gestational diabetes mellitus (GDM). METHODS In a prospective cohort study, pregnant women who were enrolled prior to gestational week 16 were followed until delivery. TBA levels were tested during weeks 14-18 of gestation. Using logistic regression, we analyzed the associations between quartiles of TBA and GDM based on a 75-g oral glucose tolerance test (OGTT) at 24-28 gestational weeks. RESULTS The GDM rate was 7.9% (114/1441). The mean TBA level was higher in women with GDM than in those without GDM (2.1 ± 2.0 vs 1.5 ± 1.0 µmol/L, P = 0.000). The highest TBA level quartile (2.1-10.7 µmol/L) had a 1.78-fold (95% CI 1.01, 3.14) increased risk of GDM compared with that of the lowest quartile (0.0-0.8 µmol/L) after adjusting for pre-pregnancy body mass index (BMI), gestational, age at TBA test and other confounders. High TBA levels were involved in the fasting glucose level rather than that at 1 h and 2 h after OGTT in all participants. CONCLUSIONS Pregnant women with higher serum TBA levels during early mid-pregnancy have a higher risk of developing GDM. TBA may be a new risk factor for GDM.

Abstract
The stress response is regulated by many mechanisms. Monoamine oxidase A (MAOA) has been related to many mental illnesses. However, few studies have explored the relationship between MAOA and acute laboratory-induced psychosocial stress with functional magnetic resonance imaging (fMRI). In the current study, the Montreal Imaging Stress Task (MIST) and fMRI were used to investigate how MAOA influences the stress response. Increased cortisol concentrations were observed after the task; functional connectivity between the bilateral anterior hippocampus and other brain regions was reduced during stress. MAOA-H allele carriers showed greater deactivation of the right anterior hippocampus and greater cortisol response after stress than did MAOH-L allele carriers. Hippocampal deactivation may lead to disinhibition of the hypothalamic-pituitary-adrenal (HPA) axis and the initiation of stress hormone release under stress. Our results suggest that the MAOA gene regulates the stress response by influencing the right anterior hippocampus.

Abstract
Variants of the serotonin transporter linked polymorphic region (5-HTTLPR) of the serotonin transporter gene SLC6A4 have been related with the onset of depression, anxiety, and other mental disorders. Homozygotes for the short 5-HTTLPR variant, referred to as the SS genotype, have greater cortisol responses to experimentally induced psychosocial stress. In the current study, we used functional magnetic resonance imaging (fMRI) to compare regional brain activations across 5-HTTLPR genotypes in subjects performing the Montreal Imaging Stress Task (MIST). Subjects with an SS genotype had significant greater increases in cortisol concentrations after the task than subjects with at least one long 5-HTTLPR allele. Additionally, relative to L carriers, the SS group had greater activation in the dorsomedial prefrontal cortex(dmPFC), dorsal anterior cingulate cortex, anterior insula.

Abstract
BACKGROUND The angiography with micro-computed tomography (micro-CT) has been proved its great advantages on investigating the intra-osseous vascularity of carpal bones. But few researches have focused on the intra-hamate vascularity. This study aimed to illustrate the intra-osseous arteries of the hamate and the relationship between the intra-hamate vascularity and the avascular risk of different types of hamate fractures. METHODS Six normal cadaveric hamates were investigated with red lead (Pb3O4) micro-CT angiography. The intra-osseous arteries of specimens were clearly enhanced and the three-dimensional model was reconstructed. In order to study the features of the arterial entrances and intra-hamate vascularity, the diameters, quantities, locations of enhanced arteries, and the locations of transversal/proximal pole fracture lines on the body of the hamate were statistically compared. Besides, in order to analyze the relationship between intra-hamate vascularities and different hamate fractures, 127 cases of hamate fractures who presented in our hospital from March 2003 to June 2017 were retrospectively studied. RESULTS A total of 94 cases were followed up (range: 4-37 months; mean: 12.4 months) effectively. The overall union rate of hamate fractures was as high as 92.6% (87 of 94 cases), while non-union of fracture on hamate hook was more common (P = 0.031). The arterial entrances were located around the dorsal, volar, radial, ulnar non-articular surfaces of the hamate body and the hook of the hamate. Generally, there were one to two trunk arteries on the volar non-articular surface and one to three trunk arteries on the dorsal non-articular surface. They formed one or two arterial arches, from which some branches were emitted and supplied the proximal parts. The intra-osseous vascularities of the hamate body were generally located in the radial part. The blood supply of the hook was mainly from the volar non-articular surface in most specimens. Hamate fractures could be classified into four types: fractures of the transversal/proximal pole, medial tuberosity, dorsal coronal of the hamate body, and fractures of the hamate hook. CONCLUSIONS This study showed new features of intra-hamate vascularity and the results will guide surgeons to reduce the vascular damage during the hamate fracture operations. The fracture lines of different types of hamate fractures may disrupt the intra-hamate arteries. The intra-hamate vascularities will have different influences on the avascular risks of different hamate fractures.

Abstract
OBJECTIVE Individuals with higher neuroticism are vulnerable to stress and are prone to develop depression, however, the neural mechanisms underlying it have not been clarified clearly. METHOD The Montreal Imaging Stress Task (MIST) was administered to 148 healthy adults during functional magnetic resonance imaging (fMRI). Whole-brain voxel-wise regression analyses were used to detect associations of neuroticism with neural activity involved in perceiving and processing psychosocial stress. In addition, two-sample t-tests were conducted between the high-neurotic and low-neurotic group in order to supplement the results found in regression analyses. RESULTS Higher neuroticism scores were associated with higher activities in the posterior cingulate cortex (PCC)/precuneus and thalamus (p < 0.05, false discovery rate correction). Moreover, two sample t-tests also revealed that the high-neurotic group had higher neural stress responses in precuneus and bilateral thalamus in comparison to the low-neurotic group (p < 0.05, false discovery rate correction). LIMITATIONS Our study mainly recruited young adults, which may limit the generalizability of our findings. CONCLUSIONS Our findings highlight the crucial role of PCC/precuneus and thalamus in the association between neuroticism and stress and may provide insight into the cognitive model of depression.

Abstract
OBJECTIVE Apolipoprotein E (ApoE) is mainly synthesized in the liver. So far, it is unknown the relationship among APOE gene polymorphisms and WML, brain atrophy. Therefore, the aim of the study was to assess the associations of APOE gene polymorphisms in patients with WML and brain atrophy. METHODS A total of 58 patients with WML, 128 patients with brain atrophy, 112 patients with co-occurrence of WML and brain atrophy and 95 healthy elderly volunteers were recruited from Renmin Hospital of WuHan University. RESULTS Allele E3 was the most common allele. The alleles E2 had significantly higher levels of ApoB and lower age in WML group. The alleles E2 was associated with the lower level of ApoB, LDL-Ch, TCh, and sdLDL in co-occurrence group. The E3/E3 genotype has higher level of sdLDL, but lower age and female frequency in WML. The E3/E4 genotype had higher level of TG, but lower age in WML. Gender, Age, E2, Hyperhomocysteinemia and UA were also significantly associated with disease progression. CONCLUSION This study found that clinical data, lipids and metabolic complications were closely related to ApoE genotypes and alleles, and also disease progression and type.

Abstract
Background Childhood maltreatment is a strong risk factor for the development of depression in later life. However, the neurobiological mechanisms underlying this vulnerability are not well understood. As depression has been associated with dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis and increased responsiveness to psychosocial stressors, we speculated that childhood maltreatment may lead to lasting alteration of the stress response system, thereby increasing the risk of depression. This study investigated the effects of childhood maltreatment on the stress response in healthy subjects while controlling for psychiatric condition. Methods Forty-eight healthy young adults (24 females) with childhood maltreatment experience and 48 healthy controls (33 females) without such experience were administered the Montreal Imaging Stress Task during functional magnetic resonance imaging. Childhood maltreatment experience was assessed using the 28-item Childhood Trauma Questionnaire (CTQ). Between-group differences in subjective stress levels, whole brain activations and cortisol levels were assessed. Results Relative to healthy control subjects, individuals exposed to childhood maltreatment exhibited higher subjective stress and cortisol levels. Neurofunctionally, participants with histories of childhood maltreatment displayed significantly increased activation in the dorsolateral prefrontal cortex (dlPFC), insula and precuneus, and decreased activation in ventromedial prefrontal cortex (vmPFC) relative to healthy controls during the psychosocial stress task. Activations in dlPFC and insula correlated with CTQ scores in the childhood maltreatment group. Conclusion The results of this study show that childhood maltreatment induces lasting changes in brain function and HPA-axis responsiveness to stress. The observed abnormal activation in the dlPFC, insula and vmPFC and enhanced cortisol response are similar to those seen in individuals with depression. This dysfunction might serve as a diathesis that embeds latent vulnerability to psychiatric disorders, and this mechanism provides evidence supporting the stress sensitization model.

Abstract
BACKGROUND The high recurrence of major depressive disorder (MDD) may derive from underlying state-independent structural alterations. METHODS First-episode drug-naïve currently depressed (cMDD) patients (N = 97), remitted depressed (RD) patients (N = 72), and healthy controls (HCs, N = 100) underwent structural magnetic resonance imaging (MRI). Group differences in cortical thickness (CT), surface area (SA), and local gyrification index (lGI) were analyzed in FreeSurfer. RESULTS Both groups of depressed patients had significantly decreased CT, relative to HCs, in the left precentral gyrus and significantly increased lGI values in the left superior frontal gyrus (SFG) indicative of state-independent alterations. Relative to HCs, the cMDD group had decreased CT of the SFG, caudal middle frontal gyrus (MFG), posterior cingulate cortex (PCC), and lateral occipital regions as well as increased SA or lGI of the superior temporal gyrus, precuneus, and pericalcarine, whereas the RD group had increased SA or lGI of the SFG, caudal MFG, and supramarginal gyrus; these alterations appeared to be state-dependent. SA or lGI values of the fusiform gyrus, inferior temporal gyrus, and superior parietal lobule differed between the cMDD and RD groups, consistent with state-dependent alterations. Beck depression inventory scores correlated with CT or lGI values of the caudal MFG, lateral occipital cortex in depressed patients. LIMITATIONS The structural features of several subcortical limbic regions were not analyzed. CONCLUSIONS Left precentral gyrus CT and left SFG gyrification alterations may represent state-independent alterations in MDD.

Abstract
OBJECTIVE The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a self-report questionnaire that retrospectively provides screening for a history of childhood abuse and neglect, and which is widely used throughout the world. The current study aimed to examine the psychometric properties of the Chinese version of the CTQ-SF. METHODS Participants included 3431 undergraduates from Hunan provinces and 234 depressive patients from psychological clinics. Confirmatory factor analysis was performed to examine how well the original five-factor model fit the data and the measurement equivalence of CTQ-SF across gender. Internal consistency was also evaluated. RESULTS The five-factor model achieved satisfactory fit (Undergraduate sample TLI = 0.925, CFI = 0.936, RMSEA = 0.034, SRMR = 0.046; depressive sample TLI = 0.912, CFI = 0.923, RMSEA = 0.044, SRMR = 0.062). Measurement invariance of the five-factor model across gender was supported fully assuming different degrees of invariance. The CTQ-SF also showed acceptable internal consistency and good stability. CONCLUSION The current study provides that the Chinese version of the Childhood Trauma questionnaire-short form has good reliability and validity among Chinese undergraduates and depressive samples, which also indicates that the CTQ-SF is a good tool for child trauma assessment.

Abstract
Pancreatic ductal adenocarcinoma is a most deadly malignancy, with a 5-year survival rate of ~7%. Chemotherapy is the main treatment strategy of this disease. However, the high rate of resistance to chemotherapeutic agent contributes to poor prognosis. MicroRNAs are essential for the initiation, progression and chemoresistance of human malignancies. Previous studies have shown that miRNA-1285 participates in renal cell carcinoma and hepatocellular carcinoma. However, its roles in pancreatic ductal adenocarcinoma are poorly understood. In this study, we confirmed that miR-1285 was significantly down-regulated in gemcitabine-resistant pancreatic cancer cell lines by qRT-PCR. We found that miR-1285 suppressed cell proliferation as well as increased the sensitivity of PDAC cells to gemcitabine by CCK8 assays in vitro. Results from transwell assay indicated that miR-1285 inhibited pancreatic cancer cell migration and invasion. Experiments using different cell lines got identical results. All those results demonstrated that miR-1285 act as tumor suppressor of pancreatic cancer. To our knowledge, this study is the first to elucidate the function of miR-1285 in pancreatic cancer. Western blotting analysis verified that miR-1285 negatively regulated YAP1 protein level, together with EGFR and β-catenin. YAP1 is a known oncoprotein of pancreatic cancer. As silencing of YAP1 activity might be beneficial in cancer prevention and treatment, our results suggest that miR-1285 might serve as a novel therapeutic target for miRNA-based therapy in pancreatic cancer. Further research elucidating the exact mechanisms of miRNA-1285 function and the correlation between miR-1285 levels in tissues or serum and clinical characteristics of pancreatic cancer is needed later.

Abstract
Purpose: Although efforts have been made to identify neurobiological characteristic of major depressive disorder (MDD) in recent years, trait- and state-related biological characteristics of MDD still remains unclear. Using functional magnetic resonance imaging (fMRI), the aim of this study was to explore whether altered spontaneous neural activities in MDD are trait- or state- related. Materials and Methods: Resting-state fMRI data were analyzed for 72 current MDD (cMDD) patients (first-episode, medication-naïve), 49 remitted MDD (rMDD) patients, and 78 age- and sex- matched healthy control (HC) subjects. The values of amplitude of low-frequency fluctuation (ALFF) were compared between groups. Results: Compared with the cMDD group, the rMDD group had increased ALFF values in the left middle occipital gyrus, left middle temporal gyrus and right cerebellum anterior lobe. Besides, compared with the HC group, the cMDD group had decreased ALFF values in the left middle occipital gyrus. Further analysis explored that the mean ALFF values in the left middle occipital gyrus, left middle temporal gyrus and right cerebellum anterior lobe were correlated positively with BDI scores in rMDD patients. Conclusion: Abnormal activity in the left middle occipital gyrus, left middle temporal gyrus and right cerebellum anterior lobe may be state-specific in current (first-episode, medication-naïve) and remitted (medication-naïve) depression patients. Furthermore, the state-related compensatory effect was found in these brain areas.

Abstract
The computer-assisted surgery (CAS) has significantly improved the accuracy, reliability and outcomes of traumatic, spinal, nerve surgery and many other operations with a less invasive way. The application of CAS for scaphoid fractures remains experimental. The related studies are scanty and most of them are cadaver researches. Some intrinsic defects from the registration procedure, scan and immobilization of limbs may inevitably result in deviations. Some deviations become more obvious with operations of small bones (such as scaphoid) although they are acceptable for spine and other orthopedic surgeries. We reviewed the current literatures on the applications of CAS for scaphoid operation and summarized technical principles, scan and registration methods, immobilization of limbs and their outcomes. On the basis of the data, we analyzed the limitations of this technique and envisioned its future development.

Abstract
We investigated the intraosseous arteries of six normal cadaveric scaphoids using red lead injection and three-dimensional reconstruction with micro-computed tomography. The arterial entrances were generally located around the dorsal ridge, the insertion of the scaphocapitate ligament and the radial part of the radioscaphocapitate ligament. Two to three trunk arteries entered the scaphoid on dorsal ridge at the level of the waist. The distal part of the scaphoid was mainly supplied by arteries from the waist. The blood supply of about 40% of proximal part of the scaphoid was poor. The blood supply from the scaphoid dorsal ridge plays an important role, not only for the proximal part of the scaphoid, but also for the waist and even the distal pole. The intrascaphoid arterial pattern may be contributory to nonunion, especially in proximal pole fractures.

Abstract
Objective To investigate pathogenesis, diagnosis, and treatment of crush syndrome of chest and arm. Methods Between January 2010 and January 2015, 5 cases of crush syndrome of chest and arm caused by pressing oneself in a coma after CO poisoning or alcoholic intoxication were treated. There were 4 males and 1 female with an average age of 36.7 years (range, 28-46 years). Two patients involved left upper limb and chest, while the other three patients involved right upper limb and chest. The crushed time ranged from 4 to 12 hours (mean, 7 hours). All 5 cases received emergency decompression and vacuum sealing drainage (VSD). After surgery, the patients were transferred to Intensive Care Unit to receive continuous renal replacement therapy (CRRT). The wounds were repaired with skin grafts after the patients' condition were stable. Results The hospitalization time was 26-48 days (mean, 33 days). Necrosis of the skin graft occurred in 1 case, which cured after debridement and skin graft again. The skin graft survived in the other cases and the wounds healed by first intension. Five patients were followed up 12-18 months (mean, 15 months). At last follow-up, the results were excellent in all 5 cases according to the assessment criteria proposed by GU Yudong. The patients got full recovery of their upper limb activities and sensation. All the patients returned to the normal life and work. Conclusion CO poisoning, drunkenness, and pressing oneself together will lead the crush syndrome to severe and rapid progress. The key of the treatment is a comprehensive therapy including a thorough and rapid tension reduction to save the limb function, CRRT, and correction of anemia and electrolyte imbalance.

Abstract
We systematically examined the factor structure and criterion validity across the full scale and 10 short forms of the Center for Epidemiological Studies Depression Scale (CES-D) with Chinese youth. Participants were 5,434 Chinese adolescents in Grades 7 to 12 who completed the full CES-D; 612 of them further completed a structured diagnostic interview with the major depressive disorder (MDD) module of the Kiddie Schedule for Affective Disorder and Schizophrenia for School-age Children. Using a split-sample approach, a series of 4-, 3-, 2-, and 1-factor models were tested using exploratory structural equation modeling and cross-validated using confirmatory factor analysis; the dimensionality was also evaluated by parallel analysis in conjunction with the scree test and aided by factor mixture analysis. The results indicated that a single-factor model of depression with a wording method factor fitted the data well, and was the optimal structure underlying the scores of the full and shortened CES-D. Additionally, receiver operating characteristic curve analyses for MDD case detection showed that the CES-D full-scale scores accurately detected MDD youth (area under the curve [AUC] = .84). Furthermore, the short-form scores produced comparable AUCs with the full scale (.82 to .85), as well as similar levels of sensitivity and specificity when using optimal cutoffs. These findings suggest that depression among Chinese adolescents can be adequately measured and screened for by a single-factor structure underlying the CES-D scores, and that the short forms provide a viable alternative to the full instrument.

Abstract
BACKGROUND ADH1B Arg48His polymorphism is associated with the development of alcohol-related diseases. In this study, we aimed to explore an improved polymerase chain reaction with confronting two-pair primers (PCR-CTPP) assay for the detection of ADH1B Arg48His polymorphism. METHODS A mismatch was introduced at the 3' end of each of the two allele-specific to increase the specificity of the reaction. But beyond that, a new mismatch at-3 positions of outer primers was designed to decrease the efficiency of the aforementioned primers and depresses the amplification of an internal nonspecific DNA control. A total of 180 samples from healthy volunteers Han Chinese were tested to evaluate this new assay. RESULTS The protocol of PCR-CTPP was successful for genotyping of ADH1B Arg48His. The results from the improved PCR-CTPP assay were confirmed by Sanger sequencing, and correct genotyping rates were 100%.The genotype frequencies were 49.44% (89 cases) for His/His, 46.67% (84 cases) for Arg/His, and 3.89% (seven cases) for Arg/Arg respectively. CONCLUSIONS This improved PCR-CTPP assay is simple, rapid, cost-effective, and reliable, specific for the detection of ADH1B Arg48His polymorphism in most clinical diagnostic laboratories.

Abstract
BACKGROUND The etiology of Kienböck's disease is controversial, and the blood supply is a possible pathogenic factor. The red lead (Pb3O4) angiography with micro-computed tomography (micro-CT) of lunate to investigate intralunate arteries has rarely been reported. This study aimed to investigate a new, reasonable, and simplified technique to study the intraosseous arterial pattern of normal lunates. METHODS This study investigated the intraosseous arterial pattern of six normal cadaveric lunates through Pb3O4injection and three-dimensional reconstruction with micro-CT. The intraosseous arteries of all specimens were clearly enhanced. The data of enhanced arteries and nutrient foramina were shown as median (Q1, Q3) and analyzed with Wilcoxon signed-rank test. RESULTS The mean number of total nutrient foramina was 2.00 (1.75, 2.00) on the palmar side and 3.50 (2.50, 4.25) on the dorsal side. The number with enhanced arteries on the palmar side was 1.00 (0.75, 2.00) and on the dorsal side was 3.50 (1.75, 4.00). There were no significant differences between the number of nutrient foramina on the palmar and dorsal sides of the lunates, no matter the total number or enhanced arteries. The intraosseous arterial pattern in normal lunates can be classified into three types: the dominate stems from the palmar side, from the dorsal side, and from both sides with anastomosis. CONCLUSIONS The Pb3O4angiography with micro-CT is a simplified, quicker, and reliable method to study intraosseous arteries.

Abstract
Seventeen fresh lunates with stage III Kienböck's disease were scanned with micro-computed tomography. Four regions of interest were selected to measure trabecular parameters, which were compared with those from normal lunates. Within the three regions in the distal surface, there was more compact trabecular bone in the middle region when compared with the palmar and dorsal regions. In the central part, the trabeculae of the Kienböck's lunates were much thicker than those in normal lunates. The diameters of the palmar nutrient foramina of the Kienböck's lunates were significantly smaller than those in normal lunates. In affected lunates, the bony disruptions were mostly located in the palmar or dorsal areas, which were shown from trabecular bone structure analysis to be structurally weaker. This leads to separation of the distal part of the fractured bone, disruption of the blood supply, poor bone remodelling and proneness to secondary fracture and eventual collapse.
