Abstract
Rabies is a zoonotic infectious disease caused by lyssavirus and characterized by central nervous system symptoms. The fatality rate of rabies is almost 100%. About 59 000 cases die of rabies worldwide every year, mainly in Asia and Africa. China is an epidemic country of rabies. Grade II and III exposures are the main types of rabies exposures in China. Standardized post-exposure prophylaxis (PEP) can prevent rabies almost 100%. Human Rabies Vaccine Technical Working Group, National Immunization Advisory Committee and invited experts reached an expert consensus on PEP by referring to the World Health Organization's position paper on rabies vaccine in 2018 and related research progress in recent.

Abstract
Objective The anterior cingulate cortex (ACC) is associated with the processing of negative emotions. Gamma-aminobutyric acid (GABA) metabolism plays an important role in the pathogenesis of mental disorders. We aimed to determine the changes in GABA levels in the ACC of perimenopausal women with depression. Methods We recruited 120 perimenopausal women, who were followed up for 18-24 months. After reaching menopause, the participants were divided into a control group (n = 71), an anxiety group (n = 30), and a depression group (n = 19). The participants were examined using proton magnetic resonance spectroscopy (MRS). TARQUIN software was used to calculate the GABA concentrations in the ACC before and after menopause. The relationship of the GABA levels with the patients' scores on the 14-item Hamilton Anxiety Scale and 17-item Hamilton Depression Scale was determined. Results GABA decreased with time. The postmenopausal GABA levels were significantly lower in the depression group than in the anxiety group and were significantly lower in both these groups than in the normal group. The postmenopausal GABA levels were significantly lower than the premenopausal levels in the normal, anxiety, and depression groups (P = 0.014, <0.001, and <0.001, respectively). The premenopausal GABA levels did not significantly differ between the normal vs. anxiety group (P = 0.907), normal vs. depression group (P = 0.495), and anxiety vs. depression group. The postmenopausal GABA levels were significantly lower in the depression group than in the anxiety group and were significantly lower in both these groups than in the normal group, normal vs. anxiety group (P = 0.022), normal vs. depression group (P < 0.001), and anxiety vs. depression group (P = 0.047). Conclusion Changes in GABA concentrations in the anterior cingulate cortex are related with the pathophysiological mechanism and symptoms of perimenopausal depression.

Abstract
Background and purpose: Hypoperfusion plays an important role in the pathophysiology of cerebral small vessel disease (SVD). Lenticulostriate arteries (LSAs) are some of the most important cerebral arterial small vessels. This study aimed to investigate whether the number of LSAs was associated with the cerebral perfusion in SVD patients and determine the correlation between the number of LSAs and SVD severity. Methods: Five hundred and ninety-four consecutive patients who underwent digital subtraction angiography were enrolled in this study. The number of LSAs was determined. Computed tomography perfusion (CTP) was used to calculate the cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), and time to peak (TTP). Magnetic resonance imaging (MRI) was performed to assess cerebral infarct, cerebral microbleeds (CMBs), white matter hyperintensities (WMHs), enlarged perivascular spaces (EPVSs), and lacunes. An SVD compound score was calculated to express the level of cerebral SVD load. Results: The SVD scores were negatively correlated with the number of the LSAs (P < 0.001, rs = −0.44). The number of LSAs was inversely associated with the presence of any type of SVD (P < 0.001). The adjusted ORs of the SVD severity were 0.31 for LSA group 1 (LSA > 20) vs. group 2 (LSA = 10–20) and 0.47 for LSA group 2 (LSA = 10–20) vs. group 3 (LSA < 10). MTT and TTP were significantly higher and CBF was significantly lower when the number of LSAs was between 5 and 10 on each side of the basal ganglia (P < 0.001, <0.001, and <0.001, respectively). The CBV was slightly lower when the number of LSAs was between 5 and 10, while it was significantly lower when the number was <5 on each side of the basal ganglia (P < 0.05, <0.0001, respectively). Conclusion: LSA count was lower in SVD patients than the non-SVD participants and there was a positive correlation between the cerebral perfusion and the number of LSAs. The LSA number was negatively associated with SVD severity, hypoperfusion might play an important role. This finding may have potentially important clinical implications for monitoring LSA in SVD patients.

Abstract
Sympathetic activation and the kidney play critical roles in hypertension and chronic heart failure. The role of the kidney in sympathetic activation is still not well known. In this study, we revealed an excitatory renal reflex (ERR) in rats induced by chemical stimulation of the kidney that regulated sympathetic activity and blood pressure. The ERR was induced by renal infusion of capsaicin, and evaluated by the changes in renal sympathetic outflow, blood pressure, and heart rate. Renal infusion of capsaicin dose-dependently increased the contralateral renal sympathetic nerve activity, mean arterial pressure, and heart rate. Capsaicin in the cortico-medullary border had greater effects than in the cortex or medulla. Intravenous infusion of capsaicin had no significant effects. The effects of renal infusion of capsaicin were abolished by ipsilateral renal denervation, but were not affected by bilateral sinoaortic denervation. Renal infusion of capsaicin increased the ipsilateral renal afferent activity. The ERR was also induced by renal infusion of bradykinin, adenosine, and angiotensin II, but not by ATP. Renal infusion of capsaicin increased c-Fos expression in the paraventricular nucleus (PVN) of hypothalamus. Lesion of neurons in the PVN with kainic acid abolished the capsaicin-induced ERR. These findings indicate that chemical stimulation of kidney causes an excitatory reflex, leading to sympathetic activation, pressor response, and accelerated heart rate. The PVN is an important central nucleus in the pathway of the ERR.

Abstract
Background and Purpose: Remote white matter and cortex reorganization may contribute to functional reorganization and clinical outcome after acute infarcts. To determine the microstructural changes in the remote intact corticospinal tract (CST) and precentral gyrus cortex connected to the acute infarct after subcortical stroke involving the CST over 6 months. Methods: Twenty-two patients with subcortical stroke involving the CST underwent magnetic resonance imaging (MRI) and clinical assessment in the acute phase (baseline) and 6 months (follow-up) after the stroke. The MRI sequences included T1-weighted imaging, T2-weighted imaging, fluid-attenuated inversion recovery, diffusion tensor imaging (DTI), and diffusion kurtosis imaging. Fractional anisotropy (FA) and track-density imaging (TDI) values were generated using DTI data for the centrum semiovale, corona radiata, posterior limb of internal capsule, and cerebral peduncle. The mean kurtosis (MK) value of the precentral gyrus cortex was calculated. Changes in the FA, TDI, and MK values between the baseline and follow-up and the relationship between these changes were analyzed. Results: The TDI and FA values of all parts of the ipsilesional (IL) CST, including the noninvolved upper and lower parts, decreased at the 6-month follow-up (P < 0.001). The MK values of the stroke lesion (P < 0.001) and IL precentral gyrus cortex (P = 0.002) were lower at follow-up than at the baseline. The ΔTDI (r = 0.689, P < 0.001) and Δ FA values (r = 0.463, P = 0.03) of the noninvolved upper part of the IL CST were positively correlated with the ΔMK value of the IL precentral gyrus cortex. Conclusion: Secondary degeneration occurred in the remote part of the CST and the remote IL precentral gyrus cortex after subcortical stroke involving the CST. The secondary degeneration in the upper part of the CST was correlated with that in the IL precentral gyrus cortex.

Abstract
Objective: To investigate the value of colonoscopic assessment in "watch and wait" strategy for mid-lower rectal cancer after neoadjuvant chemoradiotherapy (nCRT). Methods: A single-center retrospective case series study was performed. Database of mid-lower rectal cancer patients at Department of Gastrointestinal Oncology, Peking University Cancer Hospital & Institute from March 2011 to June 2017 was retrieved. Inclusion criteria: (1) nCRT was completed (50.6 Gy/22 f, plus oral capecitabine); (2) radical surgery was performed within 12 weeks after nCRT treatment; (3) clinical response to nCRT was determined as clinical complete response (cCR) or near-cCR. Patients who did not undergo colonoscopy and MRI in our center during initial assessment and follow-up, or whose colonoscopy data were unable to re-evaluated, were excluded. Initial evaluation of nCRT response was carried out between 6 and 16 weeks after nCRT. The results of endoscopy (eCR, near-eCR and non-eCR) and MRI (mCR, near-mCR and non-mCR) were compared to local lesion relapse during follow-up. The consistency of the results of colonoscopy and MRI was evaluated by Kappa test (Kappa value of 0.21 to 0.40 indicates general consistency, 0.41 to 0.60 moderate consistency, and 0.61 to 0.80 high consistency). The non-regrowth disease-free survival (NR-DFS) curves of the eCR group and the near-eCR group were plotted by Kaplan-Meier method and compared by log-rank test. Clinical significance of colonoscopy examination in the following "watch and wait" strategy during follow-up period was analyzed. Results: A total of 32 patients were enrolled in the study, including 21 (65.6%) males and 11 (34.4%) females with a median age of 57 years old. The differentiated type of rectal cancer included 1 (3.1%) case of well-differentiated, 26 (81.2%) of moderately differentiated and 5 (15.6%) of poorly differentiated. Clinical stage of the patients included 9 (28.1%) cases of T2-3N0 and 23 (71.9%) of T2-3N+. Median follow-up period was 48 (18 to 80) months. The local regrowth rate was 34.4% (11/32) and median interval of local regrowth was 10.0 (4 to 37) months. Initial colonoscopy evaluation was carried out at a median time of 9 (5 to 19) weeks after nCRT was completed. According to endoscopic findings, patients were divided into 3 groups, including 15 cases in eCR group, 15 cases in near-eCR group and 2 cases in non-eCR group. According to the appearance of MRI, patients were divided into 3 groups, including 8 cases in mCR group, 21 cases in near-mCR group and 3 cases in non-mCR group. The regrowth rate of eCR group was lower than that of mCR group (1/15 vs. 1/8) without significant difference (P=1.000). The regrowth rate of near-eCR group was higher than that of near-mCR group [9/15 vs. 42.9% (9/21)] without significant difference as well (P=0.500). The consistency between colonoscopy and MRI in response evaluation of cCR or near-cCR after nCRT was unsatisfactory (Kappa=0.341, P=0.011). After initial evaluation, 31 patients underwent watch and wait strategy, and 1 underwent local resection. The 1- and 3-year NR-DFS in the eCR group was both 100%, which was higher than that in the near-eCR group (53.3% and 38.9%, respectively), and the difference was statistically significant (P=0.001). During watch and wait period, 11 cases developed local regrowth by colonoscopy examination and the biopsy result included 4 case of high-grade intraepithelial neoplasia (HIN), 6 cases of adenocarcinoma and 1 case of chronic mucosal inflammation. Meanwhile lateral developmental tumor of ascending colon in 1 case and of sigmoid in a case was found by colonoscopy and confirmed as HIN by postoperative pathology. Besides, 4 cases developed colonic multiple adenoma and all underwent endoscopic resection. Conclusion: Colonoscopy examination plays an important role in both initial assessment and regrowth monitoring during watch and wait strategy after nCRT treatment.

Abstract
Migration of vascular smooth muscle cell (VSMC) plays a critical role in the pathophysiology of hypertension and several other vascular diseases. Curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione), a bioactive constituent from Curcuma longa, is commonly used as a spice, food additive or dietary pigment. It has several health benefits including antioxidant, anti-inflammatory and anticancer properties. This study examined the roles of curcumin in VSMC migration in hypertension and underlying mechanism. VSMC was isolated and prepared from thoracic aorta of Wistar-Kyoto rats and spontaneously hypertensive rats (SHR). VSMC migration was evaluated with Boyden chamber assay and wound-healing assay. Curcumin attenuated VSMC migration, inhibited nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) expression and reduced interleukin (IL)-1β concentration in VSMC of SHR, which were similar to the effects of NLRP3 knockdown on IL-1β concentration and VSMC migration. Curcumin inhibited NFκB activation in VSMC of SHR, which was similar to the effects of NFκB inhibitor BAY11-7082 on NFκB activation. In another in vitro model of rat VSMC migration, curcumin also inhibited angiotensin II-induced VSMC migration, NFκB activation, NLRP3 expression and IL-1β production. Intragastric administration of curcumin in SHR attenuated hypertension and reduced NFκB activation, NLRP3 and matrix metalloproteinase-9 expressions and aortic media thickness. These results indicate that curcumin inhibits VSMC migration via inhibiting NFκB-mediated NLRP3 expression in VSMC of SHR or in angiotensin II-treated VSMC. Curcumin attenuates hypertension, vascular inflammation and vascular remodeling in SHR.

Abstract
Rabies is a zoonotic infectious disease caused by lyssavirus and characterized by central nervous system symptoms. The fatality rate of rabies is almost 100%. About 59 000 cases die of rabies worldwide every year, mainly in Asia and Africa. China is an epidemic country of rabies. Grade II and III exposures are the main types of rabies exposures in China. Standardized post-exposure prophylaxis (PEP) can prevent rabies almost 100%. Human Rabies Vaccine Technical Working Group, National Immunization Advisory Committee and invited experts reached an expert consensus on PEP by referring to the World Health Organization's position paper on rabies vaccine in 2018 and related research progress in recent.

Abstract
Objective: To analyze the epidemiological characteristics, trend and related factors of tuberculosis patients that delayed for care, in Wuhan from 2008 to 2017. Methods: Data regarding tuberculosis (TB) patients was collected from the tuberculosis management information system (TMIS), a part of the China information system for disease control and prevention from 2008 to 2017. A total of 64 208 tuberculosis patients, aged 0 to 95 years were included for the analysis. Unconditional logistic regression method was used to estimate those factors that associated with this study. Results: Days of delay among TB patients appeared as M=10 (P(25)-P(75): 3-28) day, in Wuhan, 2008-2017. The prevalence of the delay was 52.5% (33 703/64 208), presenting a downward trend from 2008 to 2017 (trend χ(2)=10.64, P<0.001), but the proportions of women and ≥65 year-olds were gradually increasing. Results from the multivariate logistic regression analysis showed that factors as: patients living far away from the city vs. near the city (OR=1.29, 95%CI: 1.25-1.35), and age above 45 years vs. younger than 25 years (the age 45-64 years group vs. aged less than 25 years group, OR=1.22, 95%CI: 1.15-1.29; the age 65 or above group vs. aged less than 25 years group, the OR=1.30, 95%CI: 1.22-1.39) were under higher risk on the delay of seeking care. Occupation, way of case-finding and classification of tuberculosis patients also appeared as influencing factors on this issue. Conclusions: Prevalence on the delay of care was 52.5% among tuberculosis patients in Wuhan, 2008-2017, but with an annual decrease. Attention should be paid to female, wrinkly or elderly tuberculosis patients regarding the delay of care on TB, in Wuhan.

Abstract
Giardia duodenalis is an important zoonotic intestinal protozoan of animals and humans. We collected 450 faecal specimens from four age groups (pre-weaned piglets, weaned piglets, juveniles, adults) of Zangxiang pigs from Shaanxi and Qinghai provinces, to investigate the prevalence and genetic diversity of G. duodenalis at the β-giardin (bg), triosephosphate isomerase (tpi) and glutamate dehydrogenase (gdh) loci using nested PCRs in the present study. A total of 28 faecal samples were positive for presence of G. duodenalis, with an overall prevalence of 6.2%. Giardia duodenalis was detected in pigs from all age groups and in both investigated provinces. Significant differences (P < 0.0001) in prevalence were observed among the four age groups with prevalence decreasing with age. Sequence analysis indicated existence of genetic diversity of G. duodenalis isolates from Zangxiang pigs, with 4, 2 and 4 haplotypes at the bg, tpi and gdh loci, respectively. Two assemblages were identified, including the zoonotic assemblage B and assemblage E, with the latter as the predominant assemblage found in both locations and all age groups except adults. The present study expanded the host range of G. duodenalis and provided fundamental data for controlling G. duodenalis infection in Zangxiang pigs.

Abstract
Background and Purpose: Vascular calcification is part of the atherosclerotic process. Intracranial artery calcification is closely associated with cerebral small vessel disease (SVD). The present study aimed to investigate the distribution pattern of intracranial arterial calcification and its association with magnetic resonance imaging (MRI) markers of SVD in patients with acute ischemic cerebrovascular disease. Methods: Two hundred and seventy six consecutive patients with transient ischemic attack (TIA) or acute ischemic stroke who underwent both computed tomography (CT) angiography and MRI were enrolled in this study. Intracranial arterial calcium scores were evaluated using Agatston method. MRI was performed to assess cerebral infarction, white matter hyperintensities (WMHs), lacunes, cerebral microbleeds (CMBs), and enlarged perivascular spaces (EPVSs). Results: Intracranial artery calcification was present in 200 (72.46%) patients, with the highest prevalence in the internal carotid arteries (ICA) (64.8%). The severity of intracranial arterial calcification was associated with the presence of WMHs (P = 0.0001), lacunes (P = 0.0001), and CMBs (P = 0.0001); however, there was no association between calcifications and the presence of EPVSs (P = 0.058). The correlation coefficients (rs) were 0.350, 0.142, 0.285, and 0.251 for WMHs, EPVSs, lacunes, and CMBs, respectively. The adjusted odds ratios (ORs) of intracranial arterial calcification were: 2.747 for WMH (grade 1-2), 3.422 for WMH (grade 3), 2.902 for lacunes, 2.449 for CMB, 0.88 for EPVS (grade 1), and 0.295 for EPVS (grade 2-4). Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD.

Abstract
Migration of vascular smooth muscle cells (VSMCs) is pivotal for vascular remodeling in hypertension. Vascular adventitial fibroblasts (AFs) are important in the homeostasis of vascular structure. This study is designed to investigate the roles of AF exosomes (AFE) in VSMC migration and underling mechanism. Primary VSMCs and AFs were obtained from the aorta of spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats. VSMC migration was evaluated with Boyden chamber assay and wound healing assay. AFE from WKY rats and SHR were isolated and identified. AFE from SHR promoted but AFE from WKY rats had no significant effect on VSMC migration. The effects of AFE on VSMC migration were prevented by an exosome inhibitor GW4869, an AT1R (Ang II [angiotensin II] type 1 receptor) antagonist losartan, or an inhibitor of ACE (angiotensin-converting enzyme) captopril. ACE contents and activity were much higher in AFE from SHR than those from WKY rats. There were no significant difference in Ang II and AT1R mRNA and protein levels between AFE from SHR and AFE from WKY rats. AFE from SHR increased Ang II and ACE contents and ACE activity in VSMCs of WKY rats and SHR. The changes of Ang II contents and ACE activity were prevented by captopril. ACE knockdown in AFs reduced ACE contents and activity in AFE from SHR and inhibited AFE-induced migration of VSMCs of WKY rats and those of SHR. These results indicate that exosomes from AFs of SHR transfer ACE to VSMCs, which increases Ang II levels and activates AT1R in VSMCs and thereby promotes VSMC migration.

Abstract
Objective: To explore the clinical outcome of advanced testicular nonseminomatous germ cell cancer patients undergoing post chemotherapy retroperitoneal lymph node dissection (PC-RPLND), and to analyze the relevant prognostic factors of lymph node pathological. Methods: A total of 43 consecutive testicular nonseminomatous germ cell cancer patients underwent PC-RPLND between March 2001 and December 2014 in Department of Urology at Sun Yat-sen University Cancer Center were retrospectively reviewed. The average age of the patients was (29.0±11.5) years (ranging from 12 to 58 years). Before PC-RPLND, 22 patients were classified as phase Ⅱ, while 21 were phase Ⅲ. Primary tumor histology revealed seminomatous elements in 19 cases, embryonal cell carcinoma in 22 cases, yolk sac tumor in 13 cases, chorionic carcinoma in 3 cases, mature teratomatous elements in 11 and immature teratomatous elements in 2 cases. Patients were treated with cisplatin-based chemotherapy after orchectomy and then underwent surgical resection of retroperitoneal lymph nodes.After PC-RPLND, all patients underwent a periodic review including the blood routine, biochemistry routine and computed tomography or ultrasonograph of the chest, the abdomen and the pelvis. The association of pathological data with patient's clinic features and the correlations between molecular features detected with each other were assessed by the t test, χ(2) and Fisher's exact test. Multivariate logistic regression were used to assess prognostic factors. Results: The median operative time was 278 minutes (ranging from 50 to 715 minutes). Median blood loss was 425 ml (ranging from 50 to 5 000 ml). Eight patients received blood transfusion intra-operatively, 2 patients underwent adjunctive surgical procedures, 4 patients developed ileus and 4 had an ascites chylosus following PC-RPLND, 1 patient had a postoperative hyperthermia and retrograde ejaculation was present in 10 patients. The transverse diameter of the residual tumor in patients ranged from 0.8 to 18.2 cm. Necrosis, teratoma and viable germ cell tumors were found in 15, 17 and 11 of all patients. The median follow-up time was 46 months (ranging from 6 to 169 months). There were 39 patients had no tumor recurrence, 7 patients were found recurrence after PC-RPLND, 5 died of malignant germ cell tumor. The normal serum lactate dehydrogenase (LDH) level before chemotherapy (HR=25.811, 95%CI: 0.678 to 982.624, P=0.017) and relative changes more than 50% in retroperitoneal lymph node size (HR=0.016, 95%CI: 0 to 0.698, P=0.032) were statistically significant prognostic factors of the presence of necrosis. Conclusions: Since most residual masses are not sensitive to chemotherapy, PC-RPLND is still an essential part of the treatment of metastatic testicular nonseminomatous germ cell cancer. Patients with the normal serum LDH level before chemotherapy and a shrinkage of 50% or more in retroperitoneal mass have a considerably chance of having necrosis in the retroperitoneum resection. This may help to refine the selection of candidates for PC-RPLND.

Abstract
Objective: To present 15 cases of inflammatory myofibroblastic tumor (IMT) in genitor-urinary system, and analyze the characteristics, diagnosis and treatment of the disease. Methods: The diagnostic and therapeutic process of 15 confirmed cases admitted to Sun Yat-sen University Cancer Center between March 2009 and September 2017 were retrospectively analyzed. Of the total cases, 11 cases were diagnosed with cystic IMT with a maximum diameter of 1.0-4.5 cm, 8 cases underwent transurethral resection of bladder tumor(TURBT)and 4 of them underwent partial cystectomy after TURBT and 3 underwent partial cystectomy directly. Two cases were renal IMT with a maximum diameter of 4.0-9.0 cm, one underwent partial nephrectomy and the other accepted radical nephrectomy. One case who was diagnosed with prostatic IMT with a maximum diameter of 3.4 cm underwent transurethral resection of the prostate (TURP) and postoperative radiotherapy. One case who was diagnosed with perineal IMT with a maximum diameter of 2.1 cm underwent tumor resection. Results: The patients were followed up for 10-32 months with a median time of 27 months. No cases relapsed during the follow-up. Conclusion: Surgery is the preferred method for treating IMT in genitor-urinary system. Retrospective study shows a good prognosis in IMT patients, but a long-term follow-up is still required.

Objective: To observe the efficacy and safety between Pegfilgrastim (PEG-rhG-CSF) and Recombinant human granulocyte colony stimulating factor (rhG-CSF) in hematological malignancy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: 157 patients after allo-HSCT were enrolled in this study from June 2015 to November 2016. Two agents of G-CSF were used to stimulate hematopoietic recovery after transplantation. There were 65 cases in PEG-rhG-CSF and 92 cases in rhG-CSF groups. Patients in PEG-rhG-CSF group were given a single subcutaneous dose of 6 mg on the first day and +8 d, while cases in rhG-CSF group were given in dose of 5 μg·kg(-1)·d(-1) by subcutaneous injection from +1 d continuing to neutrophils more than 1.5×10(9)/L, and then the indicators and survival rates in two groups after transplantation were compared. Results: ①There were no significant differences of the neutrophil implantation time[13.5 (8-12) d vs 13 (9-24) d, P=0.393] and platelet implantation time [14 (9-160) d vs 14 (9-92) d, P=0.094] between PEG-rhG-CSF and rhG-CSF groups respectively. There were no significant differences in terms of neutropenia period (P=0.435) , number of cases who got fever during neutropenia (P=0.622) , and the median time of fever in neutropenia period (P=0.460) , respectively between the two groups. There were no significant differences of erythrocyte and platelet transfusions (P=0.074, P=0.059) within 1 month after transplantation. ②There were no significant differences with regard to the incidences of acute GVHD[23.1% (15/65) vs 34.8% (32/92) , P=0.115], chronic GVHD[20.0% (13/65) vs 32.6% (32/92) , P=0.081], Ⅱ-Ⅳdegree of acute GVHD[30.0% (13/65) vs 30.4% (30/92) , P=0.287] and extensive chronic GVHD[9.2% (6/65) vs 20.7% (19/92) , P=0.135] between PEG-rhG-CSF and rhG-CSF groups. ③There were no significant differences in terms of disease free survival (DFS) (62.5% vs 61.4%, P=0.478) and overall survival (OS) (67.4% vs 67.3%, P=0.718) between PEG-rhG-CSF and rhG-CSF groups. ④There was no significant difference of the non-relapse mortality (NRM) between PEG-rhG-CSF and rhG-CSF groups[20.5% (95%CI 11.4%-37.0%) vs 32.6% (95%CI 22.2%-47.9%) , P=0.141]. The relapse rate was not statistically significant[14.9% (95%CI 7.4%-29.8%) vs 10.0% (95%CI 5.0%-20.0%) , P=0.299]. Conclusion: Compared with rhG-CSF, PEG-rhG-CSF could reduce the times of injection. There were no differences in terms of hematopoietic recovery, the incidence of GVHD, relapse rate, DFS and OS rates after allo-HSCT between two groups.

Abstract
Objective: To investigate the prevalence and associated risk factors of diabetes and prediabetes in Blang ethnic adults in Menghai county. Methods: A cross-sectional survey including 3 365 Blang ethnic adults (aged 18 and above from 5 administrative villages) was conducted from February 2017 to March 2017 in Menghai county. A questionnaire, physical examination, and blood assays were included in the survey. Finally, a total of 3 237 adults with complete data were selected into this analysis. Results: The standardized prevalence of diabetes and prediabetes in Blang ethnic adults were estimated based on the sixth national census in 2010. According to the 1999 WHO criteria, the overall standardized prevalence of diabetes and prediabetes were 8.5% (men: 10.2%, women: 6.8%) and 16.1% (men: 18.0%, women: 14.1%), in which the standardized prevalence of newly diagnosed diabetes among the total population was 7.3% (men: 8.7%, women: 5.8%). Multivariable multinominal logistic regression analyses showed that age, hypertension, hypertriglyceridemia, and central obesity were significantly positively associated with both diabetes and prediabetes, with the corresponding odds ratios of 1.74 and 1.37, 2.39 and 2.02, 2.30 and 1.34, 2.55 and 1.73, respectively. Conclusion: The prevalence of diabetes is relatively high in Blang ethnic adults in Menghai county. Improving knowledge of diabetes among the local population is one of key steps in the prevention of diabetes.

Abstract
Diffusion kurtosis imaging can be used to assess pathophysiological changes in tissue structure and to diagnose central nervous system diseases. However, its sensitivity in assessing hippocampal differences between patients with Alzheimer's disease and those with amnestic mild cognitive impairment has not been characterized. Here, we examined 20 individuals with Alzheimer's disease (11 men and 9 women, mean 73.2 ± 4.49 years), 20 with amnestic mild cognitive impairment (10 men and 10 women, mean 71.55 ± 4.77 years), and 20 normal controls (11 men and 9 women, mean 70.45 ± 5.04 years). We conducted diffusion kurtosis imaging, using a 3.0 T magnetic resonance scanner, to compare hippocampal differences among the three groups. The results demonstrated that the right hippocampal volume and bilateral mean kurtosis were remarkably smaller in individuals with Alzheimer's disease compared with those with amnestic mild cognitive impairment and normal controls. Further, the mean kurtosis was lower in the amnestic mild cognitive impairment group compared with the normal control group. The mean diffusion in the left hippocampus was lower in the Alzheimer's disease group than in the amnestic mild cognitive impairment and normal control groups, while the mean diffusion in the right hippocampus was lower in the Alzheimer's disease group than in the normal control group. Fractional anisotropy was similar among the three groups. These results verify that bilateral mean kurtosis and mean diffusion are sensitive to the diagnosis of Alzheimer's disease and amnestic mild cognitive impairment. This study was approved by the Ethics Review Board of Affiliated Sixth People's Hospital of Shanghai Jiao Tong University, China on May 4, 2010 (approval No. 2010(C)-6).

Abstract
目的 观察重组人凝血因子Ⅶa(rFⅦa)对血液病及其异基因造血干细胞移植(allo-HSCT)术后出血患者的止血疗效。 方法 以2013年5月至2016年5月住院治疗的16例合并中至重度出血的血液病患者为观察对象,非移植组及移植组患者各8例,两组患者应用rFⅦa的用法、用量无明显差异。同时,以同期15例allo-HSCT后发生肠道急性移植物抗宿主病(aGVHD)肠出血患者为对照组(未应用rFⅦa),将其与allo-HSCT后肠道aGVHD肠出血应用rFⅦa患者进行生存比较,总结患者应用rFⅦa治疗的临床疗效。 结果 ①非移植组与移植组患者中,rFⅦa止血显效率分别为75.0%(6/8)和37.5%(3/8),显效中位时间分别为38.5和63.0 h,中位总生存(OS)时间分别为201.0和29.0 d,OS率分别为50.0%(4/8)和25.0%(2/8),出血相关死亡率分别为50.0%(2/4)和83.3%(5/6)。②16例患者中显效者9例,无效者7例,显效组与无效组患者中,中位OS时间分别为268.0和24.0 d,OS率分别为66.7%(6/9)和0(0/7)。③同期肠道aGVHD合并肠出血患者,观察组(6例)与对照组(15例)患者的中位OS时间分别为25.5和20.0 d。 结论 血液病患者尤其是allo-HSCT患者出血相关死亡率高,rFⅦa治疗有一定止血疗效;显效组患者OS率较无效组高;allo-HSCT后肠道出血患者采用rFⅦa治疗止血效果不佳的原因可能与移植后导致出血的并发症控制不佳有关。

Abstract
Two new Ag(I) coordination polymers (CPs), namely, Ag(L)(Htp) (1) and [Ag(L)]·(Htp)·2H2O (2) were synthesized from the long flexible ligand of 1,6-bis(2-methylbenzimidazolyl)hexane (L), terephthalic acid (H2tp) and different silver(I) salts using hydrothermal and sonochemical methods, These CPs were characterized by elemental analysis, IR spectra, scanning electron microscopy, single-crystal and powder X-ray diffraction analysis. 1 features a uninodal 3-connected 2D hcb layered structure, while 2 exhibits an infinite 1D linear chain and ultimately extended into 3D supramolecular framework via O-H⋯O and Ag⋯O interactions. In addition, the effect of various sonication concentrations of the initial reagents, ultrasonic time and power of ultrasound irradiation on the size and morphology of nanostructured 1 and 2 were evaluated. Nano-sized 1 and 2 exhibit relatively high performance as UV light driven photocatalysts for the degradation of methylene blue.

Abstract
Objective: To investigate the role and mechanism of action of green tea polyphenols in noise-induced hearing loss. Methods: Male specific pathogen-free guinea pigs were randomly divided into normal control group with 9 guinea pigs, noise exposure group with 36 guinea pigs, and green tea polyphenol intervention group with 36 guinea pigs. Auditory brainstem response (ABR) threshold shift was examined before noise exposure and at 1, 3, 7, and 14 days of noise exposure. The surface preparation of cochlear basilar membrane was used for hair cell count and the morphology of hair cells was also observed. Western blot was used to observe the expression of cysteinyl aspartate-specific protease-9 (caspase-9) and cysteinyl aspartate-specific protease-3 (caspase-3) in cochlear tissue. Results: Both the noise exposure group and the green tea polyphenol intervention group had an increase in ABR threshold after noise exposure, and the green tea polyphenol intervention group had a significantly lower ABR threshold shift than the noise exposure group at all time points (P<0.05). Both groups had enlargement, atrophy, or loss of hair cells after noise exposure, and at 7 and 14 days of noise exposure, the noise exposure group had a significantly higher rate of abnormal hair cells than the green tea polyphenol intervention group (P<0.05). Both groups had an increase in the expression of caspase-9 and caspase-3 after noise exposure, and the noise exposure group had a significantly greater increase than the green tea polyphenol intervention group (P<0.05). Conclusion: Green tea polyphenols can reduce noise-induced hearing loss and hair cell injury, possibly by regulating the expression of caspase-9 and caspase-3.

Abstract
Objective: To investigate the current status of job burnout in clinical nurses in a grade A tertiary hospitalin Shaoxing,China and related influencing factors. Methods: In October 2016, the Nursing Burnout Scale (NBS)was used for the investigation of 304 clinical nurses in a grade A tertiary hospital.The contents of the investigation included general data(including age,education background,working years,marital status, frequency of night shifts,professional title, and way of employment), characteristics of working environment,burnout, personality characteristics,coping strategy,and psychosomatic symptoms.SPSS 18.0 was used to conduct Pearson correlation analysis of the scores of each dimension of NBS. A multivariate regression analysis was performed with the demographic features of clinical nurses as the independent variable and the scores of each dimension of NBS as the dependent variable. Results: Among the clinical nurses in this grade A tertiary hospital, the incidence rate of severe burnout was 74%.The Pearson correlation analysis showed that burnout,pessimistic personality,negative coping,and psychosomatic symptoms were positively correlated with working environment(r=0.530,0.316,0.116,and 0.502); pessimistic personality and psychosomatic symptoms were positively correlated with burnout(r=0.618 and 0.675); psychosomatic symptoms were positively correlated withpessimistic personality(r=0.540); negative coping was negatively correlated with pessimistic personality(r=-0.145).The multivariate linear regression analysis showed that department(Department of Internal Medicine or Department of Surgery,B=-0.364 and -0.428)and frequency of night shifts(<6 times/month and 6-10 times/month,B=0.199 and 0.256)were influencing factors for the score of working environment; department(Department of Internal Medicine or Department of Surgery, B=-0.350 and -0.360)was an influencing factor for the score of burnout; 1-3 working years(B=-0.238)was an influencing factor for the score of pessimistic personality; married state,1-3 working years,and department (Department of Internal Medicine or Department of Surgery)were influencing factors for the score of psychosomatic symptoms(B=0.263,-0.301,-0.322,and -0.391). Conclusion: There is a high incidence rate of job burnout among clinical nurses in this grade A tertiary hospital,which is associated with burnout,working environment, pessimistic personality,and psychosomatic symptoms.Marital status,working years,department,and frequency of night shifts are major influencing factors for job burnout.

Abstract
Objective:To evaluate the diagnostic value of ultrasound patterns of 2015 American Thyroid Association (ATA) guidelines, color Doppler flow imaging (CDFI), superb microvascular imaging (SMI), and spectral Doppler in the differentiation of benign and malignant thyroid nodules.Method:The study included 254 thyroid nodules confirmed by fine needle aspiration cytology (FNAC) or histopathologic examination. All nodules were detected by ultrasonography, SMI, CDFI and spectral Doppler respectively. Blood flow detection technologies (CDFI and SMI) were used to classify flow distribution characteristics of thyroid nodules according to Kim's grading criteria. The optimal threshold drawing from ROC curve is calculated to obtain the cut-off value of spectral Doppler.Result:①For benign solid nodules with peripheral flow distribution and malignant solid nodules with central blood flow distribution, the display rates of SMI are higher than those of the CDFI, the differences were statistically significant (P< 0.05). ②There was a significance difference in detecting benign and malignant nodules using spectral Doppler (P< 0.05). ③The specificity and accuracy of combinative modality 2015 ATA+SMI was significantly higher than that of ATA, SMI, and spectral Doppler. There was no significant difference between ATA+SMI and ATA+SMI+spectral Doppler for the sensitivity, specificity, and accuracy.Conclusion:SMI had a better detection rate of blood vessels than CDFI and contribute a certain value in differential diagnosis of benign and malignant thyroid nodules. The combination of 2015 ATA and SMI can improve diagnostic value in the differentiation between benign and malignant thyroid nodules.

Abstract
BACKGROUND Linear hypertrophic scar is a common surgical problem that can be difficult to manage, especially for the median sternotomy scar. Botulinum toxin type A (BTA) is widely used in cosmetic surgery and has been shown to improve scar quality recently. The aim of this study was to evaluate the efficacy of BTA injected in the early postoperative of median sternotomy on preventing scar formation. METHODS In this prospective randomized controlled trial, 19 consecutive patients who underwent median sternotomy were enrolled. The median sternotomy wound in each patient was divided into the upper half and the lower half. Both halves of the wound were randomized to receive the treatment with either BTA or normal saline. At 6-month follow-up, scars were assessed using the Vancouver Scar Scale, scar widths were measured, and patients were asked to evaluate their overall satisfaction. RESULTS Seventeen patients with median sternotomy wounds completed the entire study. At 6-month follow-up, the mean Vancouver Scar Scale score for the BTA-treated group was 3.44 ± 1.68 and for the normal saline control group was 6.29 ± 2.39, and there was a statistically significant difference between the two groups (P < 0.05). There were also significant improvements in scar width and patient satisfaction for the BTA-treated halves of the wounds (P < 0.05). CONCLUSIONS The study demonstrates that early postoperative BTA injection can decrease scar formation and reduce scar width in median sternotomy wounds, and the overall appearance is more satisfactory.

Abstract
Objective: To investigate whether the suppressive effects of lipoxin A4 (LXA4) on endometriosis are mediated by the regulation of autophagic activity, and to further explore the actual molecular mechanism. Methods: (1) Eutopic and ectopic endometria were obtained from 13 patients with endometriosis, and 10 eutopic endometria collected from non-endometriosis patients were used as control. The expression of the autophagy-related biochemical markers [microtubule-associated protein 1 light chain 3 (LC3) and p62] were detected by western blot. Levels of LXA4 in the biopsies were measured by ELISA. (2) Primary human endometrial stromal cells (ESC) were isolated and cultured in vitro from eutopic endometria of infertility patients with endometriosis. After treatment with exogenous LXA4 or autophagy inhibitor 3-methyladenine (3-MA) or autophagy inducer rapamycin, cell migration and invasion were evaluated by transwell assay, and autophagy was detected by western blot. (3) ESC were treated with LXA4, the gene expressions of nuclear factor kappa B (NF-κB) etc. were examined by quantitative real-time PCR, and the activation of NF-κB signaling was detected by western blot. (4) ESC were incubated with 10 μmol/L NF-κB inhibitor BAY11-7080, the autophagic activation was detected by western blot. Results: (1) Autophagy-related marker, LC3-Ⅱ and LC3-Ⅱ/LC3-Ⅰ ratio, showed a significant up-regulation in ectopic lesions of endometriosis compared with eutopic endometria of affected or healthy women (all P<0.05) . However, the LXA4 level significantly decreased in ectopic tissue (P<0.05) . There was a significant negative correlation between LXA4 concentration and relative expression of LC3-Ⅱ in ectopic lesions (r= -0.780, P=0.002) . (2) 10 and 100 nmol/L exogenous LXA4 could significantly down-regulate the LC3-Ⅱ protein expression and up-regulate the p62 protein expression (all P<0.05) . LXA4 markedly inhibited the invasion and migration of ESC (P<0.05) ;while the reactivation of autophagy by rapamycin almost reversed the anti-invasion and anti-migration effects of LXA4. (3) After LXA4 treatment, the expression level of NF-κB gene significantly decreased (P<0.05) . Furthermore, the results of western blot analysis showed that the nuclear translocation of NF-κB p65 was markedly down-regulated under LXA4 treatment (P<0.05) . (4) The NF-κB inhibitor BAY11-7080 markedly suppressed the autophagic activation of LXA4 (P<0.05) . Conclusion: LXA4 could inhibit the invasion and migration of ESC by down-regulating the NF-κB signaling-mediated autophagy.

Abstract
Objective: To investigate the prevalence and related factors of dyslipidemia among children and adolescents aged 6-17 years in 7 provinces in China. Methods: Using the method of stratified cluster random sampling, 93 primary and secondary schools were selected from Guangdong, Hunan, Liaoning provinces, Shanghai, Chongqing, Tianjin municipalities and Ningxia Hui Autonomous Region in China, 2012. A total of 16 434 students aged 6-17 years old with completed physical and lipid profiles parameters were selected into this study from above 93 primary and secondary schools. Dyslipidemia was determined by the definition of Expert Advice on Prevention and Treatment of Dyslipidemia in Children and Adolescents in 2009. Logistic regression model was used to explore the factors related to dyslipidemia. Results: The prevalence of elevated total cholesterol, elevated triglyceride, elevated low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol, and dyslipidemia was 5.4% (887 cases), 15.7% (2 578 cases), 3.0% (492 cases), 13.5% (2 221 cases) and 28.5% (4 679 cases) among children and adolescents aged 6-17 years, respectively. Sugary drinks intake ≥once per week (OR=1.14; 95%CI: 1.05-1.24), sedentary time >10 hours per day (OR=1.14, 95%CI: 1.01-1.28), overweight (OR=1.50, 95%CI: 1.33-1.70), and obesity (OR=2.62, 95%CI: 2.31-2.96) were significantly associated with the prevalence of dyslipidemia. Conclusion: The prevalence of dyslipidemia was high among children and adolescents aged 6-17 in 7 provinces in China, 2012. Sugary drinks intake ≥once per week, sedentary time >10 hours per day, overweight and obesity might be the risk factors of dyslipidemia among children and adolescents.

Abstract
BACKGROUND Acute lung injury (ALI) is a major component of multiple organ dysfunction syndrome (MODS) following pulmonary and systemic infection. Alveolar macrophages (AMϕ) are at the center of ALI pathogenesis. Emerging evidence has shown that cell-cell interactions in the lungs play an important regulatory role in the development of acute lung inflammation. However, the underneath mechanisms remain poorly addressed. In this study, we explore a novel function of lung epithelial cells (LEPCs) in regulating the release of exosomes from AMϕ following LPS stimulation. METHODS For the in vivo experiments, C57BL/6 wildtype (WT) mice were treated with lipopolysaccharide (LPS) (2 mg/kg B.W.) in 0.2 ml of saline via intratracheal aerosol administration. Bronchoalveolar lavage fluid was collected at 0-24 h after LPS treatment, and exosomes derived from AMϕ were measured. For the in vitro studies, LEPCs and bone marrow-derived Mϕ (BMDM) were isolated from WT or TLR4-/- mice and were then cocultured in the Transwell™ system. After coculture for 0-24 h, the BMDM and supernatant were harvested for the measurement of exosomes and cytokines. RESULTS We demonstrate that LPS induces macrophages (Mϕ) to release exosomes, which are then internalized by neighboring Mϕ to promote TNF-α expression. The secreted interleukin (IL)-25 from LEPCs downregulates Rab27a and Rab27b expression in Mϕ, resulting in suppressed exosome release and thereby attenuating exosome-induced TNF-α expression and secretion. CONCLUSION These findings reveal a previously unidentified crosstalk pathway between LEPCs and Mϕ that negatively regulates the inflammatory responses of Mϕ to LPS. Modulating IL-25 signaling and targeting exosome release may present a new therapeutic strategy for the treatment of ALI.

Abstract
The objective of the study was to investigate the effect of feeding reduced CP, AA-supplemented diets on meat quality in growing and finishing pigs as well as the related mechanism. In experiment 1, 18 growing pigs (36.5 kg BW) were assigned randomly and fed 1 of 3 corn-soybean meal diets containing either 18% CP (normal protein, NP), 15% CP (low protein, LP), or 12% CP (very low protein, VLP). In experiment 2, 18 finishing pigs (62.3 kg BW) were allotted randomly into 1 of the following diets: 16% CP (NP), 13% CP (LP), or 10% CP (VLP). In both experiments, the LP and VLP diets were supplemented with crystalline AA to achieve equal content of standardized ileal digestible lysine, methionine, threonine, and tryptophan. At the end of each experiment, all pigs were slaughtered to collect longissimus dorsi muscle (LM) samples. Samples were used for determining meat quality, intramuscular fat (IMF) content, fatty acid composition, free AA profile, and expression of genes for myosin heavy chain isoforms. Results showed that growing and finishing pigs fed the LP diets increased (P < 0.05) redness value of LM, while finishing pigs fed the LP and VLP diets decreased (P < 0.05) the shear force values. Compared with the NP diet, growing and finishing pigs fed lower CP diets had higher (P < 0.05) contents of IMF and MUFA, and lower (P < 0.05) contents of PUFA. Besides, higher (P < 0.05) expression levels of type I and/or IIa muscle fibers were observed in LP diet-fed growing and finishing pigs, and greater concentrations of taurine and tasty AA in VLP diet-fed growing and finishing pigs. Taken together, our results indicate that low-protein diets could positively affect meat quality of growing and finishing pigs, and likely through regulation of IMF content and fatty acid composition, fiber characteristics, and free AA profile in the muscle.

Abstract
Pyogenic granuloma (PG) is a common benign vascular proliferation which often occurs on the head, neck, hands, and feet. Among the various treatment options for PG, surgical excision is the most effective treatment which offers the lowest overall recurrence rates and also provides the exact diagnosis. However, it could have difficulties to do the surgery when lesions are located on the fingers and toes, especially very near to the nails, so laser may be a very good alternative choice. In this article, we evaluated the clinical efficacy and safety of neodymium-yttrium aluminum garnet (Nd:YAG) laser for treatment of PG located on the fingers and toes. Twenty-one patients with 21 PGs located on the fingers and toes were treated by multispot Nd-YAG laser. We chose monopulse (pulse width 10.5-13.5 ms; energy 100-125 J/cm2); treatment interval was 3-4 weeks. All lesions disappeared after one or two treatments. There was no apparent scar formation, no impact on the function of the fingers and toes, no damage to nail growth, and no recurrence in more than 12-month follow-up. Nd-YAG is an effective and safety treatment option for treatment of PG located on the fingers and toes.

Abstract
BACKGROUND/AIMS Fibronectin type III domain-containing 5 (FNDC5) protein is involved in the beneficial effects of exercise on metabolism. FNDC5 attenuates hepatic steatosis induced by high fat diet (HFD). Here, we examined the effects of FNDC5 on liver fibrosis and underline mechanisms. METHODS Experiments were carried out on wild-type and FNDC5-/- mice, primary mouse hepatic stellate cells (HSCs) and human hepatic stellate cell line (LX-2). The mice were fed with HFD for 6 months to induce liver fibrosis. Oxidized low density lipoprotein (oxLDL) were used to induce the activation of hepatic stellate cells and fibrosis in mouse HSCs and human LX-2 cells. H&E, Masson's trichrome staining and Sirius red staining were used for liver sections. Protein and mRNA expressions were evaluated with Western blot and RT-PCR, respectively. RESULTS FNDC5 deficiency aggravated the HFD-induced liver fibrosis and HSCs activation in mice. It exacerbated the HFD-induced inhibition of AMPK phosphorylation, upregulation of connective tissue growth factor (CTGF) and transforming growth factor-β (TGF-β), and deposition of extracellular matrix (ECM) in liver of mice. Administration of FNDC5 attenuated oxLDL-induced AMPK deactivation, HSCs activation, CTGF and TGF-β upregulation and ECM deposition in mouse HSCs. The beneficial effects of FNDC5 on oxLDL-induced AMPK dephosphorylation, HSCs activation and ECM deposition were prevented by the inhibition of AMPK with compound C in human LX-2 cells. However, the effects of FNDC5 on hepatic fibrosis in vivo in this study cannot be distinguished from its effects on adiposity and hepatic steatosis. CONCLUSIONS FNDC5 deficiency aggravates HFD-induced liver fibrosis in mice. FNDC5 plays beneficial roles in attenuating liver fibrosis via AMPK phosphorylation-mediated inhibition of HSCs activation.

Abstract
BACKGROUND Several studies have shown that diabetes confers a higher relative risk of vascular mortality among women than among men, but whether this increased relative risk in women exists across age groups and within defined levels of other risk factors is uncertain. We aimed to determine whether differences in established risk factors, such as blood pressure, BMI, smoking, and cholesterol, explain the higher relative risks of vascular mortality among women than among men. METHODS In our meta-analysis, we obtained individual participant-level data from studies included in the Prospective Studies Collaboration and the Asia Pacific Cohort Studies Collaboration that had obtained baseline information on age, sex, diabetes, total cholesterol, blood pressure, tobacco use, height, and weight. Data on causes of death were obtained from medical death certificates. We used Cox regression models to assess the relevance of diabetes (any type) to occlusive vascular mortality (ischaemic heart disease, ischaemic stroke, or other atherosclerotic deaths) by age, sex, and other major vascular risk factors, and to assess whether the associations of blood pressure, total cholesterol, and body-mass index (BMI) to occlusive vascular mortality are modified by diabetes. RESULTS Individual participant-level data were analysed from 980 793 adults. During 9·8 million person-years of follow-up, among participants aged between 35 and 89 years, 19 686 (25·6%) of 76 965 deaths were attributed to occlusive vascular disease. After controlling for major vascular risk factors, diabetes roughly doubled occlusive vascular mortality risk among men (death rate ratio [RR] 2·10, 95% CI 1·97-2·24) and tripled risk among women (3·00, 2·71-3·33; χ2 test for heterogeneity p<0·0001). For both sexes combined, the occlusive vascular death RRs were higher in younger individuals (aged 35-59 years: 2·60, 2·30-2·94) than in older individuals (aged 70-89 years: 2·01, 1·85-2·19; p=0·0001 for trend across age groups), and, across age groups, the death RRs were higher among women than among men. Therefore, women aged 35-59 years had the highest death RR across all age and sex groups (5·55, 4·15-7·44). However, since underlying confounder-adjusted occlusive vascular mortality rates at any age were higher in men than in women, the adjusted absolute excess occlusive vascular mortality associated with diabetes was similar for men and women. At ages 35-59 years, the excess absolute risk was 0·05% (95% CI 0·03-0·07) per year in women compared with 0·08% (0·05-0·10) per year in men; the corresponding excess at ages 70-89 years was 1·08% (0·84-1·32) per year in women and 0·91% (0·77-1·05) per year in men. Total cholesterol, blood pressure, and BMI each showed continuous log-linear associations with occlusive vascular mortality that were similar among individuals with and without diabetes across both sexes. INTERPRETATION Independent of other major vascular risk factors, diabetes substantially increased vascular risk in both men and women. Lifestyle changes to reduce smoking and obesity and use of cost-effective drugs that target major vascular risks (eg, statins and antihypertensive drugs) are important in both men and women with diabetes, but might not reduce the relative excess risk of occlusive vascular disease in women with diabetes, which remains unexplained.

Abstract
Objective: To investigate the accuracy of arrhythmia detection algorithm and the effectiveness of Reveal LINQ insertable cardiac monitor (ICM). Methods: This single-center, descriptive, non-controlled clinical study was designed to enroll consecutive patients who were implanted with Reveal LINQ ICM in Minneapolis Veterans Affairs Medical Center from June 19, 2014 to April 18, 2017. The safety of implant procedure, the accuracy of automatic arrhythmia detection algorithm and the clinical effectiveness were evaluated and validated independently by two physicians. Results: Sixty patients with average age of (65±13) years (30-89 years) were enrolled and the follow-up duration was 466 days (30-1 072 days). Of these, 57 patients are male. The indications of ICM implantation were unexplained syncope in 35 cases, cryptogenic stroke in 13 cases, atrial fibrillation (AF) management in 5 cases, and palpitations in 7 cases. The implantation procedure was safe and successful in all patients without complications. The detection accuracy of arrhythmia algorithm was 86% (620/723), 82% (2 369/2 876), and 30% (411/1 380) for tachycardia, bradycardia, and pause events, respectively. The detection accuracy of arrhythmia algorithm for AF was 17% (5/30), 60% (1 569/2 632) and 69% (172/251) for cryptogenic stroke, unexplained syncope, and AF management, respectively. Important clinical findings were observed in 15% (9/60) patients. Only 5% (3/60) patients had important findings based on the intended clinical indications. Conclusion: The Reveal LINQ ICM is a safe, simple, and effective procedure for the detection of tachycardia and bradycardia events. However, the automatic AF and pause events detection algorithm had high false positive rate which requires further improvement.

Abstract
OBJECTIVE To analyze the epidemic situation of blood pressure (BP) status and its association with nutritional status among Chinese children and adolescents aged 7-18 years old in 2014, and to provide important scientific basis for the control of students' hypertension. METHODS All the subjects aged 7 to 18 years in both genders were sampled from 2014 Chinese national surveys on students' constitution and health. BP status was evaluated according to Chinese national gender-, age- and height-specific references, including hypertension (HTN), elevated hypertension (elevated HTN), isolated systolic HTN (SHTN), isolated diastolic HTN (DHTN) and mix HTN. Their nutritional status was evaluated using the international obesity task force (IOTF) definition, including thinness (severe thinness and moderate thinness), normal, overweight and obesity (severe obesity and moderate obesity). The Logistics method was used to analyze the association between BP status and nutritional status. The population attributable risk (PAR%) of overweight and obesity for BP status was calculated. RESULTS The prevalence of HTN and elevated HTN among the Chinese children and adolescents aged 7-18 years in 2014 was 14.9% and 9.2%, respectively. And the prevalence of isolated SHTN, isolated DHTN and mix HTN was 3.1%, 8.8% and 3.0%, respectively. The prevalence estimates for HTN differed the greatest for the boys, those in rural, those with high age, those in the East, and those with high BMI. The highest prevalence of HTN was detected in those with severe obesity with 44.2% and 38.8% in the boys and girls respectively, which was 2.8-fold and 3.7-fold than those with normal groups. The negative association was detected between HTN and thinness, but the positive association with overweight and obesity. The PAR% of HTN due to overweight and obesity was 16.2%, and the expected prevalence of HTN was 12.5% if controlling for overweight and obesity. Higher PAR% of isolated SHTN and mix HTN due to overweight and obesity was detected in the Chinese children and adolescents with proportions of 28.7% and 35.1%. CONCLUSION The prevalence of HTN among the Chinese children and adolescents aged 7-18 years was still high, whose components mainly focused on isolated DHTN. Overweight and obesity can increase the risk of HTN in children and adolescents significantly, especially for isolated SHTN and mix HTN. Controlling for overweight and obesity can decrease the risk of HTN among Chinese national children and adolescents largely, which can play an important role in preventing the occurrence of chronic disease in adults.

Abstract
By synthesizing nitrogen-doped graphene (NG) via a facile thermal annealing method, a fine control of the amount and location of doped nitrogen as well as the oxygen-containing functional groups is achieved with varying annealing temperature. The favorable magnetic properties have been achieved for N-doped rGO samples obtained at two temperatures of all NG samples, i.e., 500 °C and 900 °C with saturation magnetization of 0.63 emu g-1 and 0.67 emu g-1 at 2 K, respectively. This is attributed to the optimized competition of the N-doping and reduction process at 500 °C and the dominated reduction process at 900 °C. NG obtained at 300 °C affords the best overall absorbing performance: when the absorber thickness is 3.0 mm, the maximum absorption was -24.6 dB at 8.51 GHz, and the absorption bandwidth was 4.89 GHz (7.55-12.44 GHz) below -10 dB. It owes its large absorbing intensity to the good impedance match and significant dielectric loss. The broad absorption bandwidth benefits from local fluctuations of dielectric responses contributed by competing mechanisms. Despite the significant contribution from materials loss to the absorption, the one quarter-wavelength model is found to be responsible for the reflection loss peak positions. Of particular significance is that an appropriate set of electromagnetic parameters associated with reasonable reduction is readily accessible by convenient control of annealing temperature to modulate the microwave absorbing features of graphene. Thus, NG prepared by thermal annealing promises to be a highly efficient microwave absorbent.

Abstract
BACKGROUND Obesity-induced chronic inflammation is critical in the pathogenesis of insulin resistance, and the recruitment and proinflammatory activation of adipose tissue macrophages (ATMs) is important for the development of this process. Here, we examined the effects of fibronectin type III domain-containing 5 (FNDC5) on inflammation and insulin resistance in high-fat diet-induced obese mice. MATERIALS AND METHODS Male wild-type (WT) and FNDC5-/- mice were fed with standard chow (Ctrl) or high fat diet (HFD) for 20 weeks to induce obesity and insulin resistance. Firstly, effects of FNDC5 gene deletion on obesity, insulin resistance, macrophage accumulation and polarization and adipose tissue inflammation were determined in mice. Secondly, the macrophage polarity shift was further examined with flow cytometry in isolated stromal vascular fraction (SVF). Thirdly, the effects of exogenous FNDC5 on lipopolysaccharide (LPS)-induced macrophage polarization, inflammation and the underlying signaling mechanism were investigated in RAW264.7 macrophages and primary mouse peritoneal cavity macrophages (PMs). Finally, the therapeutic effects of FNDC5 overexpression were examined in HFD-induced obese WT and FNDC5-/- mice. RESULTS FNDC5 gene deletion aggravated obesity, insulin resistance, fat accumulation and inflammation accompanied with enhanced AMPK inhibition, macrophages recruitment and M1 polarization in mice fed with HFD. Exogenous FNDC5 inhibited LPS-induced M1 macrophage polarization and inflammatory cytokine production via AMPK phosphorylation in both RAW264.7 macrophages and PMs. FNDC5 overexpression attenuated insulin resistance, AMPK inhibition, M1 macrophage polarization and inflammatory cytokine production in adipose tissue of obese WT and FNDC5-/- mice. CONCLUSIONS FNDC5 attenuates adipose tissue inflammation and insulin resistance via AMPK-mediated macrophage polarization in HFD-induced obesity. FNDC5 plays several beneficial roles in obesity and may be used as a therapeutic regimen for preventing inflammation and insulin resistance in obesity and diabetes.

Abstract
Objective: To investigate the association between the single nucleotide polymorphisms (SNPs) at rs1043618, rs2075800, and rs2763979 in human heat shock protein 70 (HSP70) gene and susceptibility to noise-induced hearing loss (NIHL) . Methods: A case-control study was performed, and 5 934 workers exposed to noise in an iron and steel plant in Henan, China, who underwent physical examination from 2006 to 2015, were enrolled as study subjects. According to the criteria of binaural average high - frequency (3000, 4000, and 6000 Hz) hearing threshold≥40 dB (HL) and monauralaverage speech-frequency (500, 1000, 2000 Hz) hearing threshold≥26 dB (HL) on the basis of binauralhigh frequency loss measured by pure tone audiometry, as well as the exclusion of NIHL, a total of 286 workers were enrolled as hearing loss group; after the adjustment for sex, type of work, age (difference≤5 years) , and working years of noise exposure (difference ≤2 years) , 286 workers were enrolled as control group. A 2 ml blood genomic DNA extraction kit was used to perform DNA extraction for the peripheral blood samples, and a multiple SNP typing kit was used to determine the genotypes at the three loci in 572 samples. The association between the SNPs at the three loci and susceptibility to NIHL was analyzed. Results: In all workers, the equivalent sound level (L(Aeq)) of noise was 75.0~96.8 dB (A) . The hearing loss group had a significantly higher binauralhigh - frequencyhearing threshold than the control group (t=56.908, P<0.05) . With CC+TC genotype as control, TT genotype at rs2763979 in HSP70 gene was associated with the susceptibility to NIHL (OR=1.731, 95%CI 1.021-2.935) . In the group with cumulative noise exposure of 96 dB (A) ·year, TT genotype at rs2763979was associated with the susceptibility to NIHL (OR=5.694, 95%CI 1.256-25.817) . The rs1043618 and rs2075800 loci of HSP70 were not associated with the susceptibility to NIHL (both P>0.05) . After the adjustment for confounding factors including smoking and drinking, haplotype CCT was associated with the susceptibility to NIHL (OR=1.425, 95%CI 1.035-1.961) . Conclusion: TT genotype at rs2763979 of HSP70 gene and haplotype CCT are risk factors for NIHL.

Abstract
Objectives: To observe the correlation between the different ultrasonic manifestations of gouty arthritis and the indexes of bone destruction (Dickkopf-1, RANKL), in order to further explore the role of musculoskeletal ultrasonography in the diagnosis and monitoring of gouty arthritis. Methods: 160 cases of gouty arthritis from clinic of the Department of Rheumatology of Peking University People's Hospital between July 2016 and June 2017 were recruited in this study. These patients were examined by musculoskeletal ultrasonography (bilateral first metatarsophalangeal joints, bilateral ankle joints and bilateral knee joints). Grouping was based on ultrasound features of joints. Group A showed no aggregate .Group B showed aggregate and double contour signs. Group C showed tophus and bone erosion. Serum concentrations of Dickkopf-1 and RANKL were measured. The correlations of Dickkopf-1 or RANKL and clinical/laboratory parameters were analyzed. Results: (1)There was a significant difference in Dickkopf-1 concentration between the three groups(P<0.001). And the group C[(1 722.2±482.7)ng/L]was higher than the group B[(1 309.3±496.4)ng/L](t=4.418, P<0.001), and the group B was higher than group A[(807.9±373.8)ng/L](t=6.137, P<0.001). (2)There was a significant difference in RANKL concentration between the three groups (P<0.001). And the group C[(0.78±0.47)ng/L]was higher than the group B[(0.35±0.29)ng/L](t=5.456, P<0.001), and the group B was higher than group A[(0.10±0.09)ng/L](t=6.923, P<0.001). (3)The level of Dickkopf-1 was associated with the disease duration(r=0.430, P<0.001), and the level of RANKL was associated with the disease duration(r=0.359, P<0.001). Conclusion: Aggregates, double contour signs, tophus and bone erosion can be observed in the ultrasonic examination of gouty arthritis. And the longer the duration of the disease, the more likely the extent of bone destruction is. Joint ultrasound can be the first imaging examination for the extent of joint involvement in gouty arthritis. And the longer the duration of the disease, the more likely the extent of bone destruction is. Musculoskeletal ultrasonography can be the preferred imaging method for detecting the extent of joint involvement in gouty arthritis.

Abstract
The early hearing loss in diabetic patients is not easy to be perceived, therefore, comprehensive and complete audiological examination is necessary. At present, hearing loss in diabetes patients characterized by high frequency decline, some of the examination for high frequency hearing loss such as speech audiometry and extended high frequency are applicated. In addition, electrophysiological techniques have also been rapidly developed in animal experiments. This review summarized the audiological characteristics in diabetes patients and progress in animal experiments, which provided the basis for early diagnosis and early treatment of hearing loss in diabetes mellitus.

Abstract
The relationship of altered DNA 5'-hydroxymethylation in human spermatozoa with seminal parameters remains unclear. The aim of the study was to investigate the association between the 5'-hydroxymethylcytosine (5hmC) rate in the promoters of acetylcholinesterase (AChE) and homeobox C4 (HoxC4) genes and human sperm concentration/motility. The study population consisted of three groups: asthenozoospermia (AZ), oligoasthenozoospermia (OAZ) and normozoospermia (NZ). The 5hmC rate in the promoter was measured by CCGG loci-dependent MspI/HpaII restriction mapping of glycosylation-modified sperm DNA combined with a hydroxymethylation-specific real-time polymerase chain reaction assay. The 5hmC rate in the AChE promoter in group AZ and OAZ was higher than that in group NZ (p < .05). A weak inverse correlation between 5hmC rate of AChE and sperm motility was observed in all subjects (r = -.172, p < .05). The 5hmC rate in the HoxC4 promoter in group OAZ was lower than that in group NZ (p < .05). These results indicated that altered 5hmC rates of AChE and HoxC4 promoters are associated with low sperm motility and sperm concentration respectively.
