Abstract
Objective: To explore the epidemiological characteristics and risk factors of catheter-associated urinary tract infections in patients with perineal and/or hip burns. Methods: This study was a retrospective case series study. From January 2018 to December 2022, 260 patients with perineal and/or hip burns and urinary catheters indwelling who met the inclusion criteria were admitted to the Department of Burns and Wound Repair of the Second Affiliated Hospital of Zhejiang University School of Medicine, including 192 males and 68 females, aged 20-93 years. The total incidence of catheter-associated urinary tract infections in patients with perineal and/or hip burns, the detection of pathogenic bacteria, and the resistance of major Gram-negative and Gram-positive bacteria to commonly used antimicrobial drugs in clinic were recorded. According to whether catheter-associated urinary tract infection occurred or not, the patients were divided into infection group (43 cases) and non-infection group (217 cases). The basic conditions including gender, age, total burn area, depth of perineal burn, depth of hip burn, and burn site on admission, complications of diabetes mellitus, inhalation injury, and hypoproteinaemia, invasive operations including tracheotomy and non-perineal/hip debridement/skin transplantation surgery, duration of catheter retention, number of urethral catheterization, and bladder irrigation of patients between the two groups were compared, and the independent risk factors influencing the occurrence of catheter-associated urinary tract infections in patients with perineal and/or hip burns were screened. Results: The total incidence of catheter-associated urinary tract infections in patients with perineal and/or hip burns in this study was 16.5% (43/260). The pathogens detected were predominantly Gram-negative, followed by fungi; the main Gram-negative bacterium was Klebsiella pneumoniae, and the main Gram-positive bacterium was Enterococcus faecalis. The resistance rates of Klebsiella pneumoniae to amoxicillin/clavulanic acid, amitraz, amikacin, ciprofloxacin, ceftriaxone, and levofloxacin were higher than 70.0%, the resistance rates of Klebsiella pneumoniae to cefoxitin, cefoperazone/sulbactam, cefepime, meropenem, imipenem, and piperacillin/tazobactam ranged from 56.3% to 68.8%, and the resistance rates of Klebsiella pneumoniae to ceftazidime and tigecycline were lower than 50.0%. The resistance rates of Enterococcus faecalis to ciprofloxacin and penicillin were both 85.7%, the resistance rates of Enterococcus faecalis to erythromycin, clindamycin, moxifloxacin, and tetracycline ranged from 14.3% to 57.1%, and the resistance rates of Enterococcus faecalis to linezolid, tigecycline, and vancomycin were all 0. The differences were statistically significant between the two groups in terms of gender, status of complication of hypoproteinaemia, depth of perineal burn, status of non-perineal/hip debridement/skin transplantation surgery, status of bladder irrigation, number of urethral catheterization, and duration of catheter retention of patients (with χ2 values of 7.80, 4.85, 10.68, 9.11, and 16.48, respectively, and Z values of -4.88 and -5.42, respectively, P<0.05). There were no statistically significant differences in the age, total burn area, complications of diabetes mellitus and inhalation injury, burn site, depth of hip burns, and status of tracheotomy of patients between the two groups (P>0.05). Multifactorial logistic regression analysis showed that gender, deep partial-thickness perineal burns, non-perineal/hip debridement/skin transplantation surgery, bladder irrigation, and duration of catheter retention were the independent risk factors for catheter-associated urinary tract infections in patients with perineal and/or hip burns (with odds ratios of 2.86, 2.63, 2.79, 2.34, and 1.04, respectively, with 95% confidence intervals of 1.21-6.73, 1.03-6.71, 1.03-7.59, 1.05-5.22, and 1.02-1.06, respectively, P<0.05). Conclusions: The incidence of catheter-associated urinary tract infections is high in patients with perineal and/or hip burns, with Klebsiella pneumoniae as the predominant pathogenic bacteria having a high resistance rate to commonly used antimicrobial drugs in clinic. Gender, deep partial-thickness perineal burns, non-perineal/hip debridement/skin transplantation surgery, bladder irrigation, and duration of catheter retention are the independent risk factors for catheter-associated urinary tract infections in patients with perineal and/or hip burns.

Abstract
Waldenstrom macroglobulinemia (WM) is a type of incurable, indolent B-cell lymphoma that is prone to relapse. Over time, treatment strategies have progressed from cytotoxic drugs to rituximab (R)- or bortezomib (V)-based regimens, and have now entered into an era of Bruton tyrosine kinase inhibitor (BTKi)-based regimens. However, the optimal treatment for the relapsed patients is still unclear. Herein, we analyzed the outcomes of the first- and second-line therapies in 377 patients with WM to illustrate the optimal choices for second-line therapy. After a median follow-up of 45.4 months, 89 patients received second-line therapy, and 53 patients were evaluated for response. The major response rates (MRR) of first- and second-line treatment were 65.1% and 67.9% (P = 0.678). The median progression-free survival (PFS) for the second-line therapy (PFS2) was shorter than that for the first-line therapy (PFS1) (56.3 vs 40.7 months, P = 0.03). However, PFS2 in targeted drugs group (R-/V-/BTKi-based regimens) was comparable to PFS1 (60.7 months vs 44.7 months, respectively, P = 0.21). Regarding second-line therapy, patients who underwent sequential treatment escalation-such as transitioning from cytotoxic drugs to R-/V-/BTKi-based regimens or from R-/V-based to BTKi-based regimens (escalation group) -had higher MRR (80.6% vs 47.1%, respectively, P = 0.023) and longer PFS2 (50.4 vs 23.5 months, respectively, P < 0.001) compared to the non-escalation group. Patients in the escalation group also had longer post-relapse overall survival compared with the non-escalation group (median, 50.4 vs 23.5 months, respectively, P = 0.039). Our findings indicate that sequential treatment escalation may improve the survival of patients with WM.

Abstract
OBJECTIVE To carry out combined genetic analysis on two patients suspected for Burkitt lymphoma to facilitate their diagnosis and treatment. METHODS G banded karyotyping and interphase and metaphase fluorescence in situ hybridization (FISH) were used to detect the specific sites of chromosomes by using separate and fusion probes. RESULTS The separate probe showed no presence of MYC gene abnormality, while fusion probe confirmed the IGH::MYC translocation in the samples. Combined with the clinical features and pathological characteristics, the two patients were finally diagnosed with Burkitt lymphoma, which was confirmed by targeted capture next generation sequencing. CONCLUSION The separate probe for the MYC gene has some shortcomings and should be used together with dual fusion probe to improve the accuracy of diagnosis.

Abstract
Protecting human health from fine particulate matter (PM) pollution is the ambitious goal of clean air actions, but current control strategies largely ignore the role of source-specific PM toxicity. Here, we proposed health-oriented control strategies by integrating the unequal toxic potencies of the most polluting industrial PMs. Iron and steel industry (ISI)-emitted PM2.5 exhibit about one order of magnitude higher toxic potency than those of cement and power industries. Compared with the current mass-based control strategy (prioritizing implementation of ultralow emission standards in the power sector), the proposed health-oriented control strategy (priority control of the ISI sector) could generate 5.4 times higher reduction in population-weighted toxic potency-adjusted PM2.5 exposure among polluting industries in China. Furthermore, the marginal abatement cost per unit of toxic potency-adjusted mass of ISI-emitted PM2.5 is only a quarter of that of the other two sectors under ultralow emission scenarios. We highlight that a health-oriented air pollution control strategy is urgently required to achieve cost-effective reductions in particulate exposure risks.

Abstract
Objective: This retrospective, single-center study aimed to evaluate the efficacy and safety of programmed death-1 (PD-1) inhibitors, either as monotherapy or in combination with chemotherapy, in the management of relapse/refractory classical Hodgkin's lymphoma (R/R cHL) . Methods: A total of 35 patients with R/R cHL who received treatment at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from September 2016 to December 2020 were enrolled in this study. Among them, 17 patients received PD-1 inhibitor monotherapy (PD-1 inhibitor group), while 18 patients received a combination of PD-1 inhibitor and chemotherapy (PD-1 inhibitor + chemotherapy group). Clinical data and follow-up information were retrospectively analyzed, and survival analysis was conducted using the Kaplan-Meier method and Cox proportional hazards model. Results: The median age of the 35 patients with R/R cHL was 29 years (range: 11-61 years), with 54.3% being male. According to the Ann Arbor staging system, 62.9% of patients presented with advanced (stage Ⅲ/Ⅳ) disease, and 48.6% had extranodal involvement. Before PD-1 inhibitor therapy, the median number of prior lines of therapy was 2 (range: 1-3). Objective responses were observed in 28 patients, including 22 complete response (CR) cases, resulting in an overall response rate (ORR) of 80.0% and a CR rate of 62.9%. Specifically, the ORR and CR rates were 64.7% and 58.8%, respectively, in the PD-1 inhibitor group and 94.4% and 66.7%, respectively, in the PD-1 inhibitor + chemotherapy group. Among the 18 patients who underwent sequential autologous hematopoietic stem cell transplantation (auto-HSCT) [13 CR and five partial response (PR) cases], eight patients received PD-1 inhibitor therapy after auto-HSCT as consolidation therapy. All patients maintained a CR status after transplantation, and they exhibited significantly improved progression-free survival (PFS) rates compared with those who did not undergo sequential auto-HSCT (4-year PFS rates: 100% vs 53.5% ; P=0.041). The incidence of immune-related adverse events was 29%, with only one patient experiencing grade≥3 adverse reactions, which indicated a favorable safety profile for the treatment approach. Conclusions: PD-1 inhibitor monotherapy demonstrates notable efficacy and sustained response in patients with R/R cHL. PD-1 inhibitors combined with chemotherapy significantly improve response rates. Additionally, for salvage therapy-sensitive patients, consolidation treatment with PD-1 inhibitors after auto-HSCT exhibits the potential for prolonging PFS.

Abstract
AIMS/INTRODUCTION Fibrosis is the principle reason for heart failure in diabetes. Regarding the involvement of long non-coding ribonucleic acid zinc finger E-box binding homeobox 1 antisense 1 (ZEB1-AS1) in diabetic myocardial fibrosis, we explored its specific mechanism. MATERIALS AND METHODS Human cardiac fibroblasts (HCF) were treated with high glucose (HG) and manipulated with plasmid cloning deoxyribonucleic acid 3.1-ZEB1-AS1/microribonucleic acid (miR)-181c-5p mimic/short hairpin RNA specific to sirtuin 1 (sh-SIRT1). ZEB1-AS1, miR-181c-5p expression patterns, cell viability, collagen I and III, α-smooth muscle actin (α-SMA), fibronectin levels and cell migration were assessed by reverse transcription quantitative polymerase chain reaction, cell counting kit-8, western blot and scratch tests. Nuclear/cytosol fractionation assay verified ZEB1-AS1 subcellular localization. The binding sites between ZEB1-AS1 and miR-181c-5p, and between miR-181c-5p and SIRT1 were predicted and verified by Starbase and dual-luciferase assays. The binding of SIRT1 to Yes-associated protein (YAP) and YAP acetylation levels were detected by co-immunoprecipitation. Diabetic mouse models were established. SIRT1, collagen I, collagen III, α-SMA and fibronectin levels, mouse myocardium morphology and collagen deposition were determined by western blot, and hematoxylin-eosin and Masson trichrome staining. RESULTS Zinc finger E-box binding homeobox 1 antisense 1 was repressed in HG-induced HCFs. ZEB1-AS1 overexpression inhibited HG-induced HCF excessive proliferation, migration and fibrosis, and diminished collagen I, collagen III, α-SMA and fibronectin protein levels in cells. miR-181c-5p had targeted binding sites with ZEB1-AS1 and SIRT1. SIRT1 silencing/miR-181c-5p overexpression abrogated ZEB1-AS1-inhibited HG-induced HCF proliferation, migration and fibrosis. ZEB1-AS1 suppressed HG-induced HCF fibrosis through SIRT1-mediated YAP deacetylation. ZEB1-AS1 and SIRT1 were repressed in diabetic mice, and miR-181c-5p was promoted. ZEB1-AS1 overexpression improved myocardial fibrosis in diabetic mice, and reduced collagen I, collagen III, α-SMA and fibronectin protein levels in myocardial tissues. CONCLUSION Long non-coding ribonucleic acid ZEB1-AS1 alleviated myocardial fibrosis through the miR-181c-5p-SIRT1-YAP axis in diabetic mice.

Abstract
Introduction Minimal residual disease (MRD) has been recognized as an important prognostic factor of survival in patients with hematological malignancies. However, the prognostic value of MRD in Waldenström macroglobulinemia (WM) remains unexplored. Methods We analyzed 108 newly diagnosed WM patients receiving systematic therapy and assessed for MRD by multiparameter flow cytometry (MFC) using bone marrow samples. Results Of the total patients, 34 (31.5%) achieved undetectable MRD (uMRD). A hemoglobin level of >115 g/L (P=0.03), a serum albumin level of >35 g/L (P=0.01), a β2-MG level of ≤3 mg/L (P=0.03), and a low-risk International Prognostic Scoring System for WM (IPSSWM) stage (P<0.01) were associated with a higher rate of uMRD. Improvements in monoclonal immunoglobulin (P<0.01) and hemoglobin (P=0.03) levels were more evident in uMRD patients compared with that in MRD-positive patients. The 3-year progression-free survival (PFS) was better in uMRD patients compared with that in MRD-positive patients (96.2% vs. 52.8%; P=0.0012). Landmark analysis also showed that uMRD patients had better PFS compared with MRD-positive patients after 6 and 12 months. Patients who achieved partial response (PR) and uMRD had a 3-year PFS of 100%, which was significantly higher than that of patients with MRD-positive PR (62.6%, P=0.029). Multivariate analysis showed that MRD positivity was an independent factor of PFS (HR: 2.55, P=0.03). Moreover, the combination of the 6th International Workshop on WM assessment (IWWM-6 Criteria) and MRD assessment had a higher 3-year AUC compared with the IWWM-6 criteria alone (0.71 vs. 0.67). Discussion MRD status assessed by MFC is an independent prognostic factor for PFS in patients with WM, and its determination could improve the precision of response evaluation, especially in patients who achieved PR.

Abstract
The reticulons and receptor expression-enhancing proteins (REEPs) in the endoplasmic reticulum (ER) are necessary and sufficient for generating ER tubules. However, the mechanism of curvature generation remains elusive. Here, we systematically analyze components of the REEP family based on AI-predicted structures. In yeast REEP Yop1p, TM1/2 and TM3/4 form hairpins and TM2-4 exist as a bundle. Site-directed cross-linking reveals that TM2 and TM4 individually mediate homotypic dimerization, allowing further assembly into a curved shape. Truncated Yop1p lacking TM1 (equivalent to REEP1) retains the curvature-generating capability, undermining the role of the intrinsic wedge. Unexpectedly, both REEP1 and REEP5 fail to replace Yop1p in the maintenance of ER morphology, mostly due to a subtle difference in oligomerization tendency, which involves not only the TM domains, but also the TM-connecting cytosolic loop and previously neglected C-terminal helix. Several hereditary spastic paraplegia-causing mutations in REEP1 appear at the oligomeric interfaces identified here, suggesting compromised self-association of REEP as a pathogenic mechanism. These results indicate that membrane curvature stabilization by integral membrane proteins is dominantly achieved by curved, oligomeric scaffolding.

Abstract
Objective: To investigate the clinical and pathological features, treatment, and prognosis of gray zone lymphoma (GZL) . Methods: From July 2, 2013, to February 10, 2021, the clinical and pathological features, treatment, and outcomes of five patients with GZL at the Blood Diseases Hospital, Chinese Academy of Medical Sciences were studied retrospectively. Results: There were one male and 4 females, with a median age of 28 (16-51) years at diagnosis. Four patients had mediastinal (thymic) involvement, two of which had superior vena cava obstruction syndrome, and 3 patients had extra-nodal involvement. There was one case with a limited Ann Arbor stage and 4 cases with a progressive stage. Three patients had cHL-like pathomorphology with scattered Hodgkin-like cells, strongly positive for CD20, positive for CD30, and CD15 was negative; the other two patients had both cHL and DLBCL morphology, with some areas resembling Hodgkin cells and some areas resembling immunoblasts, strongly positive for CD30, and CD15 but negative CD20. Two patients were treated with cHL-like regimens for induction and achieved only partial remission; after salvage therapy with enhanced DLBCL-like regimens, all achieved complete remission (CR) . Three patients were treated with enhanced DLBCL-like immunochemotherapy regimens for induction, and two patients were effective, one of whom achieved CR. Four patients who did not achieve CR were given second or third-line salvage therapy, and all of them recovered. One patient lost parity, one died of disease progression at 35.9 months after diagnosis, and the remaining three maintained sustained remission. Conclusions: GZL is uncommon, usually affects younger patients, is mediastinal and is diagnosed using path morphology and immunophenotype. Patients with newly diagnosed GZL appear to be more sensitive to DLBCL-like immunochemotherapy regimens; relapsed or refractory patients were tended with non-cross-resistant combination chemotherapy or with new drugs.

Abstract
Temporal lobe epilepsy (TLE) is a common kind of refractory epilepsy. More than 30% TLE patients were multi-drug resistant. Some patients may even develop into status epilepticus (SE) because of failing to control seizures. Thus, one of the avid goals for anti-epileptic drug development is to discover novel potential compounds to treat TLE or even SE. Crocin, an effective component of Crocus sativus L., has been applied in several epileptogenic models to test its anti-epileptic effect. However, it is still controversial and its effect on TLE remains unclear. Therefore, we investigated the effects of crocin on epileptogenesis, generalized seizures (GS) in hippocampal rapid electrical kindling model as well as SE and spotaneous recurrent seizure (SRS) in pilocarpine-induced TLE model in ICR mice in this study. The results showed that seizure stages and cumulative afterdischarge duration were significantly depressed by crocin (20 and 50 mg/kg) during hippocampal rapid kindling acquisition. And crocin (100 mg/kg) significantly reduced the incidence of GS and average seizure stages in fully kindled animals. In pilocarpine-induced TLE model, the latency of SE was significantly prolonged and the mortality of SE was significantly decreased by crocin (100 mg/kg), which can also significantly suppress the number of SRS. The underlying mechanism of crocin may be involved in the protection of neurons, the decrease of tumor necrosis factor-α in the hippocampus and the increase of brain derived neurotrophic factor in the cortex. In conclusion, crocin may be a potential and promising anti-epileptic compound for treatment of TLE.

Abstract
Both characteristics and optimal treatment strategy for hairy cell leukemia-variant (HCL-v) remain elusive due to its rarity. We retrospectively analyzed the clinical features of HCL-v and the efficacy of first-line treatment options in a large Chinese cohort. In this study, we recruited 33 HCL-v patients (23 males and 10 females) with a median age of 59 years (range, 34-79 years). The chief complaints included abdominal mass and relative signs (67%) and abnormal complete blood count (27%). Immunophenotyping showed monoclonal B-cells positive for pan B-cell antigens and CD11c, weakly positive for CD103 and CD200, while negative for CD5, CD10, CD25, CD123, and annexin A1. No BRAF V600E mutation was detected, but TP53 abnormality was recurrent. Treatment choices included interferon-α (IFN-α) in 11 patients, chlorambucil (CLB) in 5 patients, single purine nucleoside analogs (PNA) in 3 patients, PNA plus rituximab (PNA + R) in 9 patients, and others in 3 patients. Four patients who received IFN-α or CLB treatment also underwent splenectomy. Patients who received PNA + R had a higher complete response rate (88% versus 5%, P < 0.001) and longer progression-free survival (PFS, 3-year PFS rate 42% [95% CI 1-84] vs. 16% [95% CI 3-40], P = 0.042) than those who received other regimens. Overall, HCL-v is an indolent lymphoma with unique characteristics. The PNA + R regimen is the preferred choice in the first-line treatment for HCL-v.

Abstract
Objective: To explore the correlation between blood glucose levels and the three factors of sarcopenia (muscle mass, strength and function) in older Chinese community dwellers. Methods: This is a retrospective study conducted by collecting the data of patients in Jiangsu Huaqiao Road Community Health Service Center from 2018 to 2019. Two hundred and fifty people aged 60 years or elder were selected. Among them, 101 were men and 149 were women. According to the American Diabetes Association diagnostic criteria for diabetes mellitus in 2018, they were divided into normal glucose tolerance (NGT) group, pre-diabetes group and diabetes group. The patients were assessed for sarcopenia as well. Results: Compared with those in the NGT group, muscle mass and upper limb muscle strength did not change in the diabetic group, but lower limb muscle strength and body function [walking speed, balance, short physical performance battery (SPPB)] decreased significantly in the diabetic group. Pearson correlation analyses showed that fasting plasma glucose(FPG) was negatively correlated with walking speed (r=-0.248, P=0.001), three-pose balance (r=-0.166, P=0.013) and SSPB (r=-0.213, P=0.001). Glycosylated hemoglobin A1c(HbA1c) was positively correlated with sitting and standing time (r=0.205, P=0.002), and negatively correlated with three-pose balance (r=-0.186, P=0.006) and SSPB (r=-0.154, P=0.024). Multiple regression analyses showed that FPG was negatively associated with walking speed (β=-0.125, P=0.005) and SPPB (β=-0.034, P=0.012), and that HbA1c was positively associated with sitting and standing time (β= 0.218, P =0.006) and negatively associated with three-pose balance (β=-0.143, P=0.012), and SPPB (β=-0.117, P =0.036). Conclusions: There is no significant correlation between blood glucose levels and muscle mass in the elderly; however, FPG is closely correlated with gait speed, and HbA1c is closely correlated with muscle strength of lower limbs and balance ability in the elderly.

Abstract
The role of minimal residual disease (MRD) in splenic marginal zone lymphoma (SMZL) has not been well studied. We prospectively designed a study to evaluate undetectable MRD (uMRD) by multiparameter flow cytometry as a prognostic factor. Residual disease level of <0·01% was defined as uMRD. A total of 71 newly diagnosed patients with bone marrow involvement were enrolled and all received rituximab-based therapy. The overall response rate (ORR) was 98·5% (70/71), with a complete remission (CR) rate of 54·9% (39/71). There were a total of 295 MRD detections in bone marrow and 77·4% patients (55/71) had uMRD. The 5-year progression-free survival (PFS) [(74·8 ± 6·5)% vs. (31·4 ± 12·6)%, P < 0·001] and 5-year overall survival (OS) [(87·2 ± 5·6)% vs. (68·9 ± 13·4)%, P = 0·035] were significantly higher in uMRD patients than in MRD-positive patients. The 5-year PFS in partial remission (PR) patients with positive MRD was significantly poorer than that of PR patients with uMRD [(21·1 ± 12·9)% vs. (83·3 ± 8·8)%, P = 0·005]. Multivariate prognostic analysis revealed that uMRD was an independent good prognostic factor for PFS (hazard ratio 0·162, 95% confidence interval 0·041-0·635; P = 0·009). All these results highlight uMRD as an independent prognostic factor in patients with SMZL, especially for patients who only achieve PR.

Abstract
Objective: Takayasu's arteritis involving the pulmonary artery (PTA) is uncommon, and those with pulmonary hypertension (PH) are even rarer. This study investigated the clinical features and CT findings in PTA patients with PH. Methods: A total of 40 PTA patients were retrospective selected in the First Hospital of Air Force Medical University from January 2008 to January 2018. There were 14 PTA patients with PH, including 3 male and 11 female cases, aged from 18 to 53 (29.7±9.4) years, as the study group (PTA+PH group). There were 26 PTA patients without PH, including 4 males and 22 females, aged 15-52 (28.9±8.5) years, as the control group (PTA group). The Chi-square or Fisher's test, T test of two independent samples and Mann-Whitney U rank sum test were used to compare the general information, symptoms, signs, laboratory examination data, right ventricular and pulmonary artery measurement data, and pulmonary artery CT findings between the two groups. Results: Compared with the PTA group, the patients in the PTA+PH group had longer disease duration, fewer active cases, more shortness of breath, chest distress and lower limb edema, lower blood oxygen partial pressure (PaO2) and lower ESR (all P<0.05). The width of right atrium and right ventricle in PTA+PH group was greater than that in PTA group (all P<0.05). The main CT findings of the involved pulmonary artery included lumen stenosis (39 cases, 97.5%), lumen occlusion (16 cases, 40%), wall thickening (9 cases, 22.5%), and lumen dilation (2 cases, 5.0%). Patients in the PTA+PH group had less wall thickening and mild lumen stenosis (<50%), more severe lumen stenosis (≥50%) and occlusion than those in the PTA group (all P<0.05). Conclusions: PTA patients with PH showed certain characteristics in clinical, laboratory and CT findings, which may be correlated to the stage of the disease duration, the severity, and the prognosis.

Abstract
Lipid droplets (LDs) are critical for lipid storage and energy metabolism. LDs form in the endoplasmic reticulum (ER). However, the molecular basis for LD biogenesis remains elusive. Here, we show that fat storage–inducing transmembrane protein 2 (FIT2) interacts with ER tubule-forming proteins Rtn4 and REEP5. The association is mainly transmembrane domain based and stimulated by oleic acid. Depletion of ER tubule-forming proteins decreases the number and size of LDs in cells and Caenorhabditis elegans, mimicking loss of FIT2. Through cytosolic loops, FIT2 binds to cytoskeletal protein septin 7, an interaction that is also required for normal LD biogenesis. Depletion of ER tubule-forming proteins or septins delays nascent LD formation. In addition, FIT2-interacting proteins are up-regulated during adipocyte differentiation, and ER tubule-forming proteins, septin 7, and FIT2 are transiently enriched at LD formation sites. Thus, FIT2-mediated nascent LD biogenesis is facilitated by ER tubule-forming proteins and septins.

Abstract
To investigate the effects of shipping aerosols on radiation, cloud physical properties, and near-surface PM2.5, four sensitive experiments with the WRF-Chem model were performed over coastal areas near Shanghai for July 2014. In general, the direct effect of shipping aerosols resulted in negative shortwave (SW) radiation forcing at the land surface. However, when considering the indirect effect, the downward SW radiation at the sea surface declined significantly. By the direct effect, shipping aerosols could modify cloud structure, resulting in a higher cloud base, lower cloud top, and shallower cloud depth. With the indirect effect included, both the cloud base and cloud top showed a declining trend over sea areas. The indirect effect of shipping aerosols was relatively more significant in influencing clouds. For example, the results revealed a 1.2% change of low cloud coverage from the indirect effect but only a 0.1% change due to the direct effect. Through their direct and indirect effects, shipping aerosols cause non-negligible impacts on precipitation, which are concentrated within light precipitation (<0.1 mm h-1). Finally, we concluded that after considering the shipping aerosols, the peak of the cloud droplet spectrum increases by about 50 cm-3/μm. It can be found that when the average volume radius of the cloud droplet is less than 2 μm, the number concentration of cloud droplets increases sharply, and when the average radius of the cloud drop is greater than 2 μm and less than 5 μm, the cloud droplet number concentration drops sharply.

Abstract
The changes of surface solar radiation (SSR) have significant implication for air pollution and rice yield. In this study, gridded SSR data, derived from multi-platform datasets and radiation model, were used to analyze its spatiotemporal changes over East China during 2000-2016. The results show SSR experiences dimming during 2000-2005, then turns into brightening till 2016. Both aerosol optical depth (AOD) and single scattering albedo (SSA) contribute to SSR trend. AOD dominates the spatiotemporal changes of SSR in East China, and this impact is higher in the North than the South. SSA has little impact on SSR with low AOD, but its contribution to SSR becomes important as AOD increases. Moreover, gridded planet boundary layer (PBL) was simulated by the Weather Research and Forecasting Model (WRF) and SSR-PBL relationship was also explored. Long-term evidence indicates PBL has a regulatory effect on SSR in the air pollution. Additionally, aerosol-induced radiation reduction can influence rice yield in East China, and it can result in about mean 6.74% reduction in rice yield over East China. Province-level changes of aerosol-induced reduction in rice production were also evaluated and it suggests the impact of aerosols on rice production is non-negligible, especially in Jiangsu and Anhui Province. Our study underscores the importance of aerosol pollution on surface radiation and the mitigation of aerosols is beneficial for crop production under climate change.

Abstract
RATIONALE Autologous stem cell transplantation (ASCT) is not routinely recommended as first-line choice for follicular lymphoma (FL). However, we actually have observed that young patients with extremely high-risk factors benefit from ASCT. This study aims to speculate the rationality of ASCT as first-line treatment, through 3 cases and review of the literature. PATIENT CONCERNS 3 young-adult patients with FL received ASCT as first-line treatment. DIAGNOSIS All the 3 patients were no more than 30 years old and the diagnosis of FL was confirmed by histopathological and immunohistochemical evaluations. They all had multi-organ involvements, and two of them presented with a "leukemic-like" manifestation. Compared with those in the previous literatures, the 3 patients were relatively younger and had more invasive clinical features. INTERVENTIONS The 3 patients received combined chemotherapy plus rituximab, followed by first-line ASCT. OUTCOMES All the 3 patients got complete remission and minimal residual disease negativity after ASCT, The median follow-up time was 109 (97-117) months, and all of them were in remission more than 8 years after transplant. LESSONS Guidelines for FL are mainly based on elderly patients, but are not suitable enough for all, especially for the young FL patients. For young patients with certain high-risk FL, first-line ASCT does not go against the guidelines, and should be recommended individually.

Abstract
We study proximity-induced spin-orbit coupling (SOC) in bilayer graphene/few-layer WSe2 heterostructure devices. Contact mode atomic force microscopy (AFM) cleaning yields ultraclean interfaces and high-mobility devices. In a perpendicular magnetic field, we measure the quantum Hall effect to determine the Landau level structure in the presence of out-of-plane Ising and in-plane Rashba SOC. A distinct Landau level crossing pattern emerges when tuning the charge density and displacement field independently with dual gates, originating from a layer-selective SOC proximity effect. Analyzing the Landau level crossings and measured inter-Landau level energy gaps yields the proximity-induced SOC energy scale. The Ising SOC is ∼2.2 meV, 100 times higher than the intrinsic SOC in graphene, whereas its sign is consistent with theories predicting a dependence of SOC on interlayer twist angle. The Rashba SOC is ∼15 meV. Finally, we infer the magnetic field dependence of the inter-Landau level Coulomb interactions. These ultraclean bilayer graphene/WSe2 heterostructures provide a high mobility system with the potential to realize novel topological electronic states and manipulate spins in nanostructures.

Abstract
Objective: To investigate the clinical status of lymphoid tissue neoplasms patients with bacteria bloodstream infections, bacteriology and drug susceptibility results, and provide the basis for rational clinical anti-infection option. Methods: A retrospectively analysis of clinical data and bacterial susceptibility test results of patients with bacteria bloodstream infections from September 2010 to December 2014 was conducted. Results: A total of 134 cases including 107 patients with bloodstream infections were enrolled. 84 cases were male, 50 cases were female, the median age was 31 (12-71) years old. 112 cases were agranulocytosis, and 106 cases were severe agranulocytosis (ANC<0.1×10(9)/L) . 27 cases underwent hematopoietic stem cell transplantation, 100 cases received chemotherapy[33 cases with VD (I) CP±L (vincristine+daunorubicin/idarubicin + cyclophosphamide + prednison±asparaginasum) induction chemotherapy, 41 cases with intensive chemotherapy of Hyper-CVAD/MA or MA (mitoxantrone+cytarabine) , 26 cases with other chemotherapy regimens], and 7 cases were infected without chemotherapy. 10 patients discharged from hospital owing to treatment abandoning, 120 cases were cured through anti-infective therapy, 2 patients died of bacteria bloodstream infections, 1 patient died of sudden cardiac, and 1 patient died of GVHD after allogenic hematopoietic stem cell transplantation. A total of 144 strains were isolated, including 108 strains (75.0%) of Gram-negative bacteria and 36 strains (25.0%) of Gram-positive cocci. The susceptibility of Gram-negative bacteria to the carbapenems was 98.00%, and the adjustment treatment rate of carbapenems was 3.0%. The susceptibility of Gram-negative bacteria to the other antibiotics was 60.30%, and the adjustment treatment rate was 90.5%. The susceptibility of Grampositive cocci to the carbapenems was 49.3%, and to glycopeptides and linezolid was 100.0%. Comparing all patients'empirical use of antimicrobial agents with the drugs susceptibility results of blood cultures, 80.1% of the patients'initial drug selection was sensitive. Conclusion: The lymphoid neoplasms patients experienced bacteria bloodstream infections most often after receiving the chemotherapy regimens of treating acute lymphoblastic leukemia. The majority type of bacteria was Gram-negative bacteria. Drug susceptibility test showed that susceptibility of Gram-negative bacteria to the carbapenems was the highest, and the treatment adjustment rate was obviously lower. The susceptibility of Gram-positive cocci to glycopeptides and linezolid was high, and which could be applied to the patients with Gram-positive cocci sepsis on basis of susceptibility results in general.

Abstract
Pancreatic cancer has a poor prognosis due to its rapid rate of metastasis and frequent late-stage diagnosis. An improved understanding of the molecular mechanisms underlying this disease is urgently needed to promote the development of improved diagnostic tools and more effective therapies. Apoptosis signal-regulating kinase 1 (ASK1) has been shown to be overexpressed in pancreatic cancer and to promote the proliferation of pancreatic cancer cells in a kinase activity-dependent manner. However, the molecular mechanisms by which ASK1 promotes cell proliferation remain to be elucidated. In this study, we report that the phosphorylation of end-binding protein 1 (EB1) at threonine 206 (pT206-EB1), which is catalyzed by ASK1, is increased in pancreatic cancer tissues. We further find that the level of pT206-EB1 correlates with that of ASK1 in cancer tissues. Additionally, ASK1 localizes to spindle poles, and knockdown of ASK1 results in the formation of multipolar spindles. Moreover, we show that depletion of ASK1 or disruption of EB1 phosphorylation inhibits spindle microtubule dynamics in pancreatic cancer cells. Collectively, these findings suggest that EB1 phosphorylation mediates the functions of ASK1 in pancreatic cancer development.

Abstract
OBJECTIVE To investigate the cytogenetic abnormalitis in patients with diffuse large B-cell lymphoma(DLBCL) patients with bone marrow involvement and their influence on prognosis. METHODS Conventional karyotyping was performed on bone marrow specimens in 47 DLBCL patients with histologically confirmed bone marrow involvement(BMI). The karyotyping results of bone marrow, the characteristics and clinical effect of chromosomal abnormalities were analysed. RESULTS In 47 DLBCL cases with BMI, the chromosomal abnormalities were detected in 25(53%) cases. Among them, complex karyotype was more frequent, being noted in 19(40%) patients. The most frequently involved chromosomes were chromosome 1 and 18(both 26%), others were chromosome 3(23%), 6(19%), 7, 8 and 14(13%). Among all karyotype changes, the most common numerical aberrations, in decreasing order of incidence, were trisomy 3(13%), trisomy 5, trisomy 7, trisomy 12, trisomy 18 and loss of 21(6%,each), and the most predominant structural aberrations, in decreasing order of incidence, were 1q+(17%), 1p+, 6q-, 8q+, 14q+, 18p+, 18q+ and aberrations involving band 2p21-p23 (6%,each). The prognostic impact analysis of both clinical features and cytogenetic aberrations revealed that IPI≥3 (P=0.03) or the presence of chromosomal abnormalities (P=0.005) were significantly related with poor progression free survival(PFS), and IPI≥3 (P=0.024), lactate dehydrogenase(LDH)≥ three times of the upper limit of normal (P=0.027) and the presence of chromosomal abnormalities (P=0.001) predominantly related with poor overall survival(OS). In multivariate analysis, the presence of chromosomal abnormalities was the only independently adverse factor for PFS(P=0.037, HR 2.323) and OS(P=0.015, HR 2.833). The analysis of prognostic effects of specific chromosomal aberrations showed that patients with specific cytogenetic abnormalities of 1q+, 8q+, +12, 12q+, 18p+ and aberrations involving band 2p21-23 had significantly poor PFS, and patients with specific cytogenetic abnormalities of 1q+, +3, +5, +7, 8q+, +12, 12q+ and aberrations involving band 2p21-23 had significantly poor OS. When the above mentioned specific chromosomal aberrations were analyzed with clinical covariate, the presence of chromosomal aberration of 8q+ (P=0.022, HR 2.701) and IPI≥3 (P=0.043, HR 2.949) were independently poor prognostic factors for PFS, and 1q+ (P=0.032, HR 2.973) was the independently poor prognostic factor for OS. CONCLUSION In DLBCL patients with BMI, the presence of chromosomal abnormalities is the only independently poor factor for PFS and OS, and among them, the specific cytogenetic aberrations of 8q+ or 1q+ have an independently poor prognostic impact on PFS or OS, respectively, which need to be further studied.

Abstract
Background: The established clinical staging systems (Rai/Binet) of chronic lymphocytic leukemia (CLL) cannot accurately predict the appropriate treatment of patients in the earlier stages. In the past two decades, several prognostic factors have been identified to predict the outcome of patients with CLL, but only a few studies investigated more markers together. To predict the time to first treatment (TTFT) in patients of early stages, we evaluated the prognostic role of conventional markers as well as cytogenetic abnormalities and combined them together in a new prognostic scoring system, the CLL prognostic index (CLL-PI). Methods: Taking advantage of a population of 406 untreated Chinese patients with CLL at early and advanced stage of disease, we identified the strongest prognostic markers of TTFT and, subsequently, in a cohort of 173 patients who had complete data for all 3 variables, we integrated the data of traditional staging system, cytogenetic aberrations, and mutational status of immunoglobulin heavy chain variable region (IGHV) in CLL-PI. The median follow-up time was 45 months and the end point was TTFT. Results: The median TTFT was 38 months and the 5-year overall survival was 80%. According to univariate analysis, patients of advanced Rai stages (P < 0.001) or with 11q- (P = 0.002), 17p- (P < 0.001), unmutated IGHV (P < 0.001), negative 13q- (P = 0.007) and elevated lactate dehydrogenase levels (P = 0.001) tended to have a significantly shorter TTFT. And subsequently, based on multivariate Cox regression analysis, three independent factors for TTFT were identified: advanced clinical stage (P = 0.002), 17p- (P = 0.050) and unmutated IGHV (P = 0.049). Applying weighted grading of these independent factors, a CLL-PI was constructed based on regression parameters, which could categorize four different risk groups (low risk [score 0], intermediate low [score 1], intermediate high [score 2] and high risk [score 3–6]) with significantly different TTFT (median TTFT of not reached (NR), 65.0 months, 36.0 months and 19.0 months, respectively, P < 0.001). Conclusions: This study developed a weighted, integrated CLL-PI prognostic system of CLL patients which combines the critical genetic prognostic markers with traditional clinical stage. This novel modified PI system could be used to discriminate among groups and may help predict the TTFT and prognosis of patients with CLL.

Abstract
Cancer cells are characterized by genomic instability, resulting in the accumulation of mutations that promote cancer progression. One way that genomic instability can arise is through improper regulation of the microtubule cytoskeleton that impacts the function of the mitotic spindle. In this study, we have identified a critical role for the interaction between apoptosis-linked gene 2 (ALG-2) and heme-binding protein 2 (HEBP2) in the above processes. Our data show that the gene copy numbers and mRNA levels for both ALG-2 and HEBP2 are significantly upregulated in breast and lung cancer. Coexpression of ALG-2 and HEBP2 markedly increases the cytoplasmic pool of ALG-2 and alters the subcellular distribution of HEBP2. Our data further reveal that abnormality in the ALG-2/HEBP2 interaction impairs spindle orientation and positioning during mitosis. In addition, this complex appears to modulate the dynamic properties of microtubules in cancer cells. These finding thus uncover an important function for deregulated ALG-2/HEBP2 axis in cancer development by influencing microtubule dynamics and spindle behavior, providing novel insight into the etiology and pathogenesis of cancer.

Abstract
Objective This study aims to evaluate the natural history of patients with chronic lymphocytic leukemia (CLL) and a 17p deletion (17p-) and identify the predictive factors within this subgroup. Methods The sample of patients with CLL were analyzed by fluorescencein situ hybridization for deletions in chromosome bands 11q22, 13q14 and 17p13; trisomy of bands 12q13; and translocation involving band 14q32. The data from 456 patients with or without a 17p- were retrospectively collected and analyzed.
Results The overall response rate (ORR) in patients with a 17p- was 56.9%, and patients with a high percentage of 17p- (defined as more than 25% of cells harbouring a 17p-) had a lower ORR. The median overall survival (OS) in patients with a 17p- was 78.0 months, which was significantly shorter than the OS in patients without this genetic abnormality (median 162.0 months, P<0.001). Within the subgroup with a 17p-, the progression-free survival was significantly shorter in patients at Binet stage B-C and patients with elevated lactate dehydrogenase (LDH), B symptoms, unmutatedIGHV and a high percentage of 17p-.
Conclusions These results indicated that patients with a 17p- CLL have a variable prognosis that might be predicted using simple clinical and laboratory characteristics.

Abstract
Stem cells are a unique class of cells that are capable of self-renewal and differentiation into multiple lineages. An increasing number of studies have suggested that both embryonic and adult stem cells possess primary cilia, antenna-like structures protruding from cell surfaces that are critical for sensing and transducing environmental cues. The primary cilium appears to regulate stem cells in multiple aspects, such as lineage specification and stemness maintenance. Understanding the role of primary cilia in the control of stem cell behavior could lead to the identification of new targets for regenerative therapies. Here, we discuss recent studies investigating the diverse roles of primary cilia in the regulation of stem cell properties and functions. We also propose potential new avenues for exploration in this promising field. J. Cell. Physiol. 232: 935-938, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
Cell migration, a complex process critical for tumor progression and metastasis, requires a dynamic crosstalk between microtubules (MTs) and focal adhesions (FAs). However, the molecular mechanisms underlying this event remain elusive. Herein we identify the proto-oncogenic protein Src as an important player in the regulation of the MT-FA crosstalk. Src interacts with and phosphorylates end-binding protein 1 (EB1), a member of MT plus end-tracking proteins (+TIPs), both in cells and in vitro. Systematic mutagenesis reveals that tyrosine-247 (Y247) is the primary residue of EB1 phosphorylated by Src. Interestingly, both constitutively activated Src and Y247-phosphorylated EB1 localize to the centrosome and FAs. Src-mediated EB1 phosphorylation diminishes its interactions with other +TIPs, including adenomatous polyposis coli (APC) and mitotic centromere associated kinesin (MCAK). In addition, EB1 phosphorylation at Y247 enhances the rate of MT catastrophe and significantly stimulates cell migration. These findings thus demonstrate that the Src-EB1 axis plays a crucial role in regulating the crosstalk between MTs and FAs to promote cell migration.

Abstract
OBJECTIVE To observe the frequency and explore the predictors of left ventricular reverse remodeling(LVRR) in patients with recent onset dilated cardiomyopathy(RODCM) on tailored medical therapy. METHODS Patients hospitalized with RODCM in Heart Failure Care Unit in Fuwai Hospital from October 2008 to December 2013 were reviewed and followed up to December 2014 or death or cardiac transplantation.Patients were treated with tailored medical therapy. LVRR was defined as an at least 10% increase in left ventricular ejection fraction(LVEF) and to a final level of ≥ 50% and an at least 10 mm decrease in left ventricular end-diastolic diameter(LVEDD) and to a final level of ≤ 55 mm on repeat echocardiogram. Clinical, electrocardiogram and echocardiographic variables at baseline were evaluated to identify predictors of LVRR by multivariable logistic regression analysis. RESULTS A total of 137 patients with RODCM were enrolled in this analysis. During a median follow-up period of 25 months(range 6 to 64 months) with repeat echocardiography, 46 patients(33.6%) were defined as LVRR, LVEF increased from(30.8±5.9) % at baseline to(59.7±4.6) % on follow-up(P<0.01) and LVEDD decreased from(63.8±4.0) mm at baseline to (49.6±3.5) mm on follow-up(P<0.01) in these patients. Multivariable logistic regression analysis showed that higher systolic blood pressure at presentation(per 10 mmHg(1 mm Hg=0.133 kPa) increase, OR=1.379, P<0.01), shorter QRS interval(≤ 100 ms vs. >100 ms, OR=2.959, P<0.01) and smaller LVEDD(per 5 mm increase, OR=0.684, P<0.01) at baseline were independent predictors of LVRR. CONCLUSIONS On current tailored medical therapy, LVRR could be achieved in about one third of patients with RODCM. Patients with higher systolic blood pressure on admission, shorter QRS interval and smaller LVEDD at baseline are associated with a higher likelihood of occurrence of LVRR.

Abstract
OBJECTIVE To investigate the clinical characteristics, treatment and prognosis of splenic marginal zone lymploma (SMZL). METHODS A total of 91 cases of SMZL admitted in our hospital from January 2002 to March 2013 were enrolled in this study. The clinical characteristics and immunophenotypes were summarized, and the clinical therapeute response and prognostic factors were analyzed statistically. RESULTS The median age of 91 patients was 56 (28-79); all the patients displayed splenomegaly with 73.6% of large spleen, hepatomegaly (14.6%) and lymphadenophathy (28.2%); the bone marrow involvement was observed in 98.9% patients, the B symptom was found in 47.1% patients. The positive expression of CD20 was observed in 100% patients, the positive expression of CD5 was in 8.3% patients, the positive expression of CD23 was found in 47.6% patients, no specific antigen was observed by now for SMZL. The clinical treatment showed that total ORR was 87.7%, CRR was 53.8% in chemotherapy group, chemotherapy combined with rituximab showed a better response than that of chemotherapy alone, which ORR was 100%, CRR was 72.4%, the difference between them was statistically significant. The Hb < 120 g/L, elevated LDH level and treatment without rituximab were the poor prognostic factors for PFS, while the elevated LDH level was related with OS of patients. CONCLUSION The patients with SMZL often display splenomegaly, involvement in bone marrow and absence of specific immunophenotypes. Chemotherapy combined with rituximab can definitely improve the outcome of SMZL. The Hb level, LDH level and treatment combined with or without rituximab seem to be related to the prognosis of the disease.

Abstract
OBJECTIVE To observe the clinical and biological characteristics of Non-IgM-secreting lymphoplasmacytic lymphoma (LPL) and draw the differences between non-IgM LPL and Waldenström macroglobulinemia (WM). METHODS Records of 13 patients with non-IgM LPL were retrospectively analyzed between January 2000 and December 2013. The cytogenetic aberrations were detected by fluorescence in situ hybridisation (FISH). RESULTS In the cohort, 7 males and 6 females with a median age of 63 years (range 43 to 74), two patients were IgA secreting, 6 with IgG secreting and 5 patients without monoclonal globulin. The major complaint at diagnosis included anemia associated symptom (53.8%), mucocutaneous hemorrhage and superficial lymphadenopathy (15.4%). Eight patients had B symptom at diagnosis. All of the 13 patients had bone marrow involvement and anemia, and 10 patients had 2 or 3 lineage cytopenia. In 5 patients with available immunophenotypic data, all expressed CD19, CD20, CD22 and CD25, but missed the expression of CD10, CD103 and CD38. Two cases had CD5 or sIgM positive alone. Another 2 patients were CD23 or CD11c positive and 3 patients were FMC7 positive. Cytogenetic aberrations had been detected by FISH in 7 patients, but only two (28.6%) patients had aberrations with del(6q). CONCLUSION The clinical and biological characteristics had no significantly difference between non-IgM LPL and WM.

Abstract
OBJECTIVE To assess the efficacy of dose-intensive immunochemotherapy with or without autologous hematopoietic stem cell transplantation (ASCT) for newly diagnosed young patients with medium/high risk diffuse large B-cell lymphoma (DLBCL). METHODS The retrospective study was performed in 29 cases of young patients (≤ 60 years) with newly diagnosed DLBCL and an age-adjusted International Prognostic Index (aaIPI) score of 2 or 3. All of them were treated with dose-intensive regimens (DA-EPOCH or Hyper-CVAD/MA) combined with Rituximab and some were consolidated with first-line ASCT. The efficacy and the potential predictors were evaluated. RESULTS The median age of 29 patients was 43 years old. Of them, 12 patients were consolidated with high-dose chemotherapy and ASCT. The complete remission (CR) rate was 69%, the partial remission (PR) rate 21% and the overall response rate 90%. After a median follow-up of 14 months, the estimated progression-free survival (PFS) and overall survival (OS) at two years were 64% and 70%, respectively. The median PFS and OS were significantly longer in CR patients than that in PR patients (P=0.015 and 0.061, respectively). Two patients achieved PR after induction therapy converted to CR after ASCT and were in continuous CR after follow-up above three years. In multivariate analysis, only bone marrow involvement (BMI) at diagnosis had an adverse influence in PFS (P=0.009), but not in OS. Based on whether there was BMI or not and the extent of BMI at diagnosis, the patients were divided into three groups as BM-0 (without BMI), BM-1 (the extent of BMI ≤ 10%) and BM-2 (the extent of BMI>10%). Patients in BM-2 group had significantly shorter PFS and OS than those in BM-0 and BM-1 groups (P=0.001 and 0.045, respectively). In multivariate analysis, the extent of BMI>10% was the independent poor prognostic factor for PFS and CNS relapse or prognosis. CONCLUSION Dose-intensive immunochemotherapy followed by ASCT or not has significant effect on efficacy of first-line treatment for young and untreated patients with medium/high risk DLBCL. The extent of BMI>10% at diagnosis is an independent risk factor associated with poor PFS and increased CNS relapse or progression.
