ABSTRACT
OBJECTIVE@#This study aimed to estimate spatiotemporal variations of global heat-related cardiovascular disease (CVD) burden from 1990 to 2019.@*METHODS@#Data on the burden of heat-related CVD were derived from the Global Burden of Disease Study 2019. Deaths and disability-adjusted life years (DALYs) were used to quantify heat-induced CVD burden. We calculated the age-standardized mortality rate (ASMR) and DALY rate (ASDR) per 100,000 population to compare this burden across regions. Generalized linear models were applied to evaluate estimated annual percentage changes (EAPC) for temporal trends from 1990 to 2019. The correlation between the socio-demographic index (SDI) and age-standardized rate was measured using the Spearman rank test.@*RESULTS@#Heat-induced CVD caused approximately 90 thousand deaths worldwide in 2019. Global ASMR and ASDR of heat-related CVD in 2019 were 1.17 [95% confidence interval ( CI): 0.13-1.98] and 25.59 (95% CI: 2.07-44.17) per 100,000 population, respectively. The burden was significantly increased in middle and low-SDI regions and slightly decreased in high-SDI regions from 1990 to 2019. ASMR showed an upward trend, with the most considerable increase in low-latitude countries. We observed a negative correlation between SDI and EAPC in ASMR ( r s = -0.57, P < 0.01) and ASDR ( r s = -0.59, P < 0.01) among 204 countries.@*CONCLUSION@#Heat-attributable CVD burden substantially increased in most developing countries and tropical regions.

Macrophages play an important role in maintaining homeostasis of the body, and they are also one of the most abundant immune cells in the tumor microenvironment (TME). These macrophages are often called tumor-associated macrophages (TAMs), which play an important role in the development of tumor and are an important target for tumor therapy. Studies have shown that tumor growth and metastasis can be inhibited by regulating the function of macrophages, but the therapeutic efficacy was often hampered by the poor performance of the drugs such as lack of targeting, poor solubility, low bioavailability, and severe side effects. After introduction of the background of macrophage and tumor therapy, this review focuses on the research progress of nano-drug delivery systems in the modulation of the function of macrophages to enhance tumor immunotherapy. Nano-drug delivery systems are diverse in structures and functions, and can regulate macrophage functions through a variety of mechanisms. Four important aspects of macrophage modulation, which included TAMs depletion, repolarization of TAMs, promoted phagocytosis of TAMs, and combinational modulation of TAMs were summarized. Each strategy together with typical examples was reviewed and future directions in this field were also prospected.

ABSTRACT
Solute carrier (SLC) transporters meditate many essential physiological functions, including nutrient uptake, ion influx/efflux, and waste disposal. In its protective role against tumors and infections, the mammalian immune system coordinates complex signals to support the proliferation, differentiation, and effector function of individual cell subsets. Recent research in this area has yielded surprising findings on the roles of solute carrier transporters, which were discovered to regulate lymphocyte signaling and control their differentiation, function, and fate by modulating diverse metabolic pathways and balanced levels of different metabolites. In this review, we present current information mainly on glucose transporters, amino-acid transporters, and metal ion transporters, which are critically important for mediating immune cell homeostasis in many different pathological conditions.

BACKGROUND@#Rapid visual acuity (VA) decline was a common complaint in patients with sellar/suprasellar germinoma. In our hospital, 3.4 Gy/2f of emergency irradiation was applied to save patient VA and enable subsequent chemoradiotherapy. This study aimed to investigate the efficacy of emergency irradiation with 3.4 Gy/2f in patients with sellar/suprasellar germinoma who had rapid VA decline.@*METHODS@#From January 2014 to December 2017, 33 patients with sellar/suprasellar germinoma who complained of VA decline within 3 months received 3.4 Gy/2f of emergency irradiation in Beijing Tiantan Hospital. The best-corrected VA (BCVA) and mean deviation (MD) were measured. Correlations between visual function change and clinical factors, including age at diagnosis, duration of VA decline, extent of tumor regression, serum level of tumor markers, were analyzed.@*RESULTS@#Among 33 patients with sellar/suprasellar germinoma, the median diameter and volume of sellar/suprasellar lesions were 32 mm (range: 5-55 mm) and 12.9 cm (range 0.6-58.5 cm), respectively. Data on pre- and post-emergency-irradiation BCVA were obtained in 32 patients. For the right eyes, BCVA was improved in 23 patients (71.9%), unchanged in 7 (21.9%), and worsened in 2 (6.2%); and for the left eyes, these numbers were 27 (84.4%), 4 (12.5%), and 1 (3.1%), respectively. In terms of the logarithm of the minimum angle of resolution (logarithm of the minimum angle of resolution = Log (1/BCVA) score, the improvement was significant in both eyes (P < 0.001). In terms of MD, six patients had paired data and the improvement was marginal in the right eyes (P = 0.068) and significant in the left eyes (P = 0.043). However, no clinical factor was found to have correlation with visual function improvement.@*CONCLUSION@#In sellar/suprasellar germinoma patients with VA decline, 3.4 Gy/2f of emergency irradiation was effective in improving visual function.

ABSTRACT
OBJECTIVE@#To explore the ultrastructure characteristics of patients with dampness-heat of Pi (Spleen)-Wei (Stomach) syndrome (DHPW) and Pi-qi deficiency syndrome (PQD), both of which are Helicobacter pylori (Hp)-correlated gastric diseases (HPCG), and implicate a helpful hint for the clinical microcosmic syndrome differentiation.@*METHODS@#Fourteen gastric mucosa samples from 6 chronic gastritis (CG) and 6 active peptic ulcer (including 8 DHPW, 4 PQD) as well as 2 healthy volunteers were collected and tested for Hp infection. The ultrastructure of gastric mucosa was observed under the transmission electron microscope (TEM).@*RESULTS@#Among 14 gastric mucosa samples, 8 of them were Hp positive (6 DHPW and 2 PQD), which were all accordance with the results screened by supermicro-pathological method. Under TEM, the normal gastric mucosa, with tidy microvilli and abundant in mucus granules, mitochondria and rough endoplasmic reticulum distributed evenly, and with smooth nucleus membrane. But in those specimens of DHPW with Hp infection, microvilli were presented with burr shape. Especially, those samples from dampness-heat syndrome with predominant heat type (DHSH) patients were more obvious, with microvilli damaged, mitochondria concentrated and distributed in disorder, secretory tubule extended. In dampness-heat syndrome with predominant dampness type (DHSD) patients, mucus granules aggregated obviously, mitochondria swelled and blurred, and rough endoplasmic reticulum crowded. For 2 samples of DHPW without Hp infection, their microvilli were intact, with mitochondria increased and gathered but well-distributed, and secretory tubule extended mildly. In 2 PQD patients with Hp positive, the specimens of microvilli were sparse, and their mucus granules and mitochondria were decreased, with fractured crests and vacuole, secretory tubules extension to nucleus membrane, and rough endoplasmic reticulum extension in a pool-like way, and nucleus condensed. The 2 samples from PQD patients without Hp infection were characterized with intact microvilli, decreased mitochondria, fractured crest and extended rough endoplasmic reticulum in a pool-like way.@*CONCLUSION@#It's obviously different in ultrastructure of DHPW and PQD patients under TEM, which may give a helpful hint for the microcosmic syndrome differentiation of HPCG.
ABSTRACT
Objective To assess the changes of white matter microstructure in neuromyelitis optica spectrum disorders (NMOSD) with DTI based on tract-based spatial statistics (TBSS) method.Methods Conventional MR and DTI were performed in 20 NMOSD patients (NMOSD group) and 20 healthy volunteers (control group).DTI data were analyzed with TBSS procedure,which was a part of FSL software packages,and non-parametric statistical analysis was performed on the whole brain.Correlation between FA value of tracts with significant difference in NMOSD group and expanded disability status scale (EDSS) scores was analyzed.Results TBSS analysis revealed significantly (P＜ 0.05,FWE corrected) extensive decrease of FA value in cerebrum and cerebellum white matter fiber bundles,i.e.corpus callosum,fornix,corticospinal tract,unciform fasciculus,cerebellar peduncles etc.in NMOSD group,and decrease of AD value,increase of RD value in cingulum bundle,corpus callosum and fornix,while MD value only increased in fornix and retrolenticular part of the left internal capsule (P＜0.05,FWE corrected).Negative correlations were found between FA value of left uncinate fasciculus,right external capsule,left inferior cerebellar peduncle,bilateral anterior limb of internal capsule,medial lemniscus and EDSS scores (all P＜0.05).Conclusion Widespread white matter damage is observed in cerebrum and cerebellum in NMOSD patients by using TBSS analysis,which may partly correspond to the disabilities of NMOSD patients.However,the other microstructural changes of white matter tracts may suggest complicated pathological mechanism of NMOSD.
ABSTRACT
Objective To investigate clinical effects and prognostic factors of transabdominal laparoscopic-assisted and open radical resection for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction (AEG).Methods The retrospective cohort and case-control studies were conducted.The clinicopathologieal data of 84 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to the First Affiliated Hospital of Xiamen University from January 2014 to January 2017 were collected.Among 84 patients,42 undergoing transabdominal laparoscopic-assisted radical gastectomy (LARG) were allocated into LARG group and 42 undergoing transabdominal open radical gastectomy (ORG) were allocated into ORG group.Observation indicators:(1) comparison of intraoperative and postoperative recovery situations between groups;(2)comparison of follow-up and survival situations between groups;(3) prognostic analysis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival situations,tumor recurrence and metastasis of patients up to January 2018.Measurement data with normal distribution were representde as-x±s,and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range).Comparison of count data were analyzed using the ehi-square test or Fisher exact probability.Ordinal data were compared between groups using the Mann-Whitney U nonparametric test.The survival rate and curve were respectively calculated and drawn by the Kaplan-Meier method,and Log-rank test was used for survival and univariate analyses.Multivariate analysis was done by COX proportional hazard model.Results (1) Comparison of intraoperative and postoperative recovery situations between groups:patients with Siewert type Ⅱ and Ⅲ AEG in the LARG and ORG group underwent successful transabdominal radical resection,without conversion to thoracotomy.All patients in the LARG group underwent esophagojejunostomy with circular stapler device,38 and 4 patients in the ORG group underwent esophagojejunostomy with circular stapler and linear cut stapler respectively.Operation time,volume of intraoperative blood loss,length of incision,time of postoperative analgesia,cases with anastomotic bleeding,anastomotic leakage,abdominal bleeding,incisional infection,pulmonary infection,abdominal infection and reflux esophagitis of grade Ⅰ ～ Ⅱ postoperative complications and duration of postoperative stay were respectively (261±50)minutes,(119±111)mL,(7.8±1.6)cm,(2.1±1.3)days,1,1,0,0,1,0,0,(12.8 ± 1.9) days in LARG group and (216 ± 52) minutes,(230± 178) mL,(17.3± 1.8) cm,(3.4±1.2)days,2,0,2,2,2,1,2,(18.4±15.3)days in ORG group,with statistically significances between groups (t =2.357,2.960,2.195,2.013,x2 =5.486,t =2.125,P＜0.05).All patients with complications were improved by symptomatic treatment.(2) Comparison of follow-up and survival situations between groups:81 of 84patients including 41 in LARG group and 40 in ORG group were followed up for 6-48 months,with a median time of 29 months.The postoperative 2-year overall and tumor-free survival rates were respectively 85.1％ and 82.1％ of 41 patients in LARG group and 83.1％ and 79.3％ of 40 patients in ORG group,with no statistically significance between groups (x2 =0.013,0.049,P＞0.05).(3) Prognostic analysis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection:results of univariate analysis showed that tumor diameter,tumor TNM staging,tumor T staging,tumor N staging and postoperative adjuvant chemotherapy were related factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection (x2 =8.349,14.376,9.732,17.250,8.012,P＜0.05).Results of multivariate analysis showed that tumor TNM staging and postoperative adjuvant chemotherapy were independent factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection (risk ratio =4.305,0.031,95％ confidence interval:1.858-9.977,0.004-0.246,P＜0.05).Conclusions Transabdominal laparoscopicassisted radical resection for AEG is safe and feasible,with advantage of minimally invasiveness,having equivalent long-term effects compared to open surgery.Tumor TNM staging and postoperative chemotherapy are independent factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection.
ABSTRACT
Necrosis is a form of cell death, which is related to various serious diseases such as cardiovascular disease, cancer, and neurodegeneration. Necrosis-avid agents (NAAs) selectively accumulated in the necrotic tissues can be used for imaging and/or therapy of related diseases. The aim of this study was to preliminarily investigate necrosis avidity of I-evans blue (I-EB) and its mechanism. The biodistribution of I-EB at 24 h after intravenous administration showed that the radioactivity ratio of necrotic to viable tissue was 3.41 in the liver and 11.82 in the muscle as determined by counting in model rats. Autoradiography and histological staining displayed preferential uptake of I-EB in necrotic tissues. nuclear extracts from necrotic cells exhibited 82.3% of the uptake in nuclei at 15 min, as well as 79.2% of the uptake at 2 h after I-EB incubation. The DNA binding study demonstrated that evans blue (EB) has strong binding affinity with calf-thymus DNA (CT-DNA) (=5.08×10 L/(mol/L)). Furthermore, the accumulation of I-EB in necrotic muscle was efficiently blocked by an excess amount of unlabeled EB. In conclusion, I-EB can not only detect necrosis by binding the DNA released from necrotic cells, but also image necrotic tissues generated from the disease clinically.

ABSTRACT
Objective To assess the damage of limbic system pathways in relapsing-remitting multiple sclerosis (RRMS) by diffusion tensor imaging (DTI) tractography.Methods DTI tractography was used to acquire fiber numbers,fractional anisotropy (FA),mean diffusivity (MD) of cingulum,fornix,and uncinate fasciculus (UF) in 20 RRMS patients (MS group) and 20 healthy volunteers (control group),and statistical analysis was performed.Results Compared with control group,lower FA value (P＜0.01) and higher MD value (P＜0.05) were found in cingulum,fornix and UF of MS group,and the fiber numbers of fornix decreased in MS group (P＜0.001).There were significant differences between the left and the right UF in fiber numbers and FA value of control group and the fiber numbers of MS group.Negative correlations were found between FA value of cingulum and UF and EDSS scores in MS group (r=-0.572,-0.665,both P＜0.05),and positive correlations were found between MD value and EDSS scores (r=0.627,0.603,both P＜0.05).Conclusion DTI tractography is valuable in assessing MS associated limbic system damage and in monitoring the clinical progression of the disease.
ABSTRACT
AIM: To explore the effect of pyrrolidine dithiocarbamate (PDTC), an NF-κB inhibitor, on the proliferation and apoptosis of human multiple myeloma U266 cells and its mechanisms.METHODS: The U266 cells were treated with PDTC at different concentrations (0, 25, 50, 100 and 200 μmol/L) in vitro.The growth inhibitory rate of the U266 cells was detected by CCK-8 assay and cell counting.The cell cycle of the U266 cells was determined by flow cyto-metry, and the apoptosis was examined by flow cytometry with Annexin V-FITC/PI staining.The effect of PDTC on the expression of DNA methyltransferase 1 (DNMT1) at mRNA and protein levels was measured by RT-qPCR and Western blot, respectively.The effects of PDTC on the protein levels of NF-κB (P65), DNMT1, Bcl-2, cyclin D1, cleaved caspase-3 and cleaved caspase-8 were determined by Western blot.RESULTS: The protein level of NF-κB (P65) was decreased after treatment with PDTC for 48 h or 72 h.PDTC inhibited the proliferation of U266 cells in both dose-and time-dependent manners.After treatment with PDTC for 48 h, the percentage of U266 cells in G2 phase increased compared with control group (P<0.05).PDTC induced the apoptosis of U266 cells in a dose-dependent manner.The expression of DNMT1 at mRNA and protein levels decreased (P<0.05).The results of Western blot showed that the expression of Bcl-2 in PDTC groups decreased, while the protein levels of cyclin D1, cleaved caspase-3 and cleaved caspase-8 were higher than those in control group (P<0.05).CONCLUSION: The NF-κB inhibitor PDTC inhibits the proliferation of U266 cells by inducing cell apoptosis.It may be related to the down-regulated expression of DNMT1, cell cycle arrest and activation of the apoptotic pathways.

Characteristics of collapsed tibial plateau fracture determines that the joint surface must remain anatomical reduction,line of force in tibial must exist and internal fixation must be strong. However, while renewing articular surface smoothness, surgeons have a lot of problems in dealing with bone defect under the joint surface. Current materials used for bone defect treatment include three categories: autologous bone, allograft bone and bone substitutes. Some scholars think that autologous bone grafts have a number of drawbacks, such as increasing trauma, prolonged operation time, the limited source, bone area bleeding,continuous pain, local infection and anesthesia,but most scholars believe that the autologous cancellous bone graft is still the golden standard. Allograft bone has the ability of bone conduction, but the existence of immune responses, the possibility of a virus infection, and the limited source of the allograft cannot meet the clinical demands. Likewise, bone substitutes have the problem that osteogenesis does not match with degradation in rates. Clinical doctors can meet the demand of the patient's bone graft according to patient's own situation and economic conditions.
