Objective To examine whether Tim-3 plays a protective role in paraquat poisoning induced excessive immune response and tissue damage based on the critical roles of Tim-3 controlling inflammatory response.Methods A paraquat poisoning model was established in wild type and in Tim-3 transgenic C57BL/6 mice by intraperitoneal injection of paraquat (40 mg/kg) .In addition, C57BL/6 mice with paraquat poisoning were injected with Tim-3 soluble protein( sTim-3) or control protein to see the effect of Tim-3 blocking on the progression of paraquat poisoning.Samples were collected at 6 and 24 h after paraquat injection respectively and were examined for tissue damage, cytokine expression and paraquat metabolism.Results After paraquat poisoning, there was significantly attenuated tissue damage in the lungs and kidneys and decreased TNF-α,IL-6 and IL-1 beta expression in the PBMCs or in the serum from Tim-3 transgenic mice compared to wild type mice.The serum concentration of paraquat in Tim-3 transgenic mice was also significantly decreased.However, in sTim-3 treated paraquat poisoning mice, there was significantly increased cytokine expression and tissue damage compared to control protein treated mice.The in vitro data showed that Tim-3 signaling negatively regulated macrophages mediated inflammatory response.Conclusion Tim-3 plays a critical role in maintaining the homeostasis after paraquat poisoning. Further investigation on the regulatory roles of Tim-3 in inflammation will shed new light on the pathogenesis of paraquat poisoning and provide new therapeutic strategies.

Objective To investigate the clinical characteristics of metabolically healthy obese ( MHO) individuals, and to explore the risk of progression into metabolic disorders after 3 years. Methods A total of 3943 residents in Jining City were evaluated twice from February 2012 to August 2015, and 3766 individuals were enrolled excluding those with missing data. Of the subjects, 875 subjects were screened as metabolic normal population, which were divided into MHO(n = 127), metabolically healthy overweight (MHOW, n = 386), and metabolically healthy normal weight ( MHNW, n = 362) groups. T test, x2 test, and logistic regression analysis were used for data analysis. Results The incidence of MHO was 11. 63% (127 / 1092) in obesity, and the proportion of MHO in females was higher than that in males(13. 91% vs 7. 82% , P<0. 05). Compared with MHNW group, the levels of HbA1C , fasting insulin, low density lipoprotein-cholesterol ( LDL-C), triglyceride ( TG), glutamyl transpeptidase (GGT), systolic blood pressure(SBP), diastolic blood pressure(DBP), and waist circumference(WC) were higher in MHO while glomerular filtration rate (GFR) and high density lipoprotein-cholesterol (HDL-C) were lower(all P<0. 05); and fasting insulin, LDL-C, TG, GGT, SBP, WC were higher in MHOW while HDL-C was lower (all P<0. 05). The levels of fasting insulin, TG, SBP, WC were higher in MHO while GFR and HDL-C were lower compared with MHOW(all P<0. 05). Following up for 3 years, the incidences of dyslipidemia in MHNW, MHOW, and MHO were 17. 96% (65 / 362), 32. 90% (127 / 386), 42. 52% (54 / 127), respectively, with significant difference among three groups(P<0. 05). The incidences of hyperglycemia in the three groups were 20. 17% (73 / 362), 22. 80%(88 / 386), 26. 77% (34 / 127), respectively, without significant difference among groups ( all P > 0. 05). After adjustment for some factors including sex, age, fasting insulin, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, GGT, and creatinine, the risks of dyslipidemia in MHO ( OR = 2. 193, 95% CI 1. 359-3. 539, P<0. 05) and MHOW(OR= 1. 705, 95% CI 1. 190-2. 443, P<0. 05) were significantly increased as compared with MHNW. Conclusion Compared with MHNW individuals, MHOW/ MHO individuals show an obviously different clinical feature as well as with higher risks of dyslipidemia after 3 years.

Objective:To investigate the effects of hydroxysafflor yellow A (HSYA) on depressive-like behavior and expression of type A γ-aminobutyric acid receptor(GABAAR)in hippocampus of chronic restraint stress model mice.Methods:The SPF grade male C57BL/6C mice were divided into Control group, HSYA group, Model group, Model + HSYA group and Model + fluoxetine group according to random number table method, with 12 mice in each group.Mice model of depression was established by chronic restraint stress.Mice in HSYA group and Model+ HSYA group were intraperitoneally injected with HSYA(20 mg/kg), mice in Model+ fluoxetine group were injected intraperitoneally with fluoxetine (10 mg/kg), and mice in Control group and Model group administered with 0.9% sodium chloride solution intraperitoneally once a day for 14 days.Then, the forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and the protein expression levels of different subtypes of GABAAR in the hippocampus of mice were determined by Western blot.SPSS 19.0 and GraphPad Prism 8.0 software were used for data statistical analysis and mapping.One-way ANOVA was used for comparison among groups, and Tukey-HSD test was used for further pairwise comparison.Results:(1) In the behavioral tests, there were significant differences in swimming immobility time of FST and tail suspension immobility time of TST among the five groups ( F=21.59, 20.81, both P<0.05). The swimming immobility time ((143.91±9.97) s) and tail suspension immobility time (( 107.00±6.54) s) in Model group were higher than those in Control group ((52.92±6.70) s, ( 43.50±5.96) s, both P<0.05). There were no significant difference in swimming immobility time and tail suspension immobility time between Model+ HSYA group ((26.17±7.69)s, ( 20.17±7.89)s) and Model+ fluoxetine group ((61.60±16.22)s, (34.14±10.74)s)(both P>0.05), but the swimming immobility time and tail suspension immobility time in these two groups were lower than those in Model group (both P<0.05). (2) The Western blot results showed that there were significant differences in the expression of GABAARβ1 and GABAARβ2 protein in hippocampus among the four groups ( F=12.21, 11.40, both P<0.05). The expression levels of GABAARβ1(45.60±10.76) and GABAARβ2 (46.27±4.82) protein in hippocampus of Model group were lower than those in Control group ((100.00±3.44), (100.00±3.26), both P<0.05). Compared to Model group, the expression of GABAARβ1 (79.91±5.00) and GABAARβ2 (79.08±5.53) protein in hippocampus of Model+ HSYA group were higher (both P<0.05). In addition, the expression of GABAARα1 and GABAARγ1 proteins in hippocampus were not significantly different among the four groups( F=0.23, 0.10, both P>0.05). Conclusion:HSYA can effectively alleviate depressive-like behavior in depression model mice, which may be related with the upregulation of GABAARβ1 and GABAARβ2 of hippocampus tissue.

Objective:
To investigate the biological characteristics of high hyperdiploid and triploid/tetraploid acute myeloid leukemia (HH/TT-AML) and its relationship with prognosis.
Methods:
The clinical data of 28 patients with newly diagnosed HH/TT-AML during March 2006 and June 2017 were retrospectively analyzed, and the factors influencing prognosis were analyzed by the Kaplan-Meier method.
Results:
The karyotypes of HH/TT-AML patients were mainly 49 chromosomes, accounting for 39.3% (11/28), followed by 50-55 chromosomes, accounting for 32.1% (9/28). The karyotypes of high hyperdiploid acute myeloid leukemia (HH-AML) patients were more likely to be +8 (77.3%, 17/22) or +21 (54.5%, 12/22). The survival analysis showed that the overall survival rate of HH/TT-AML patients with -5/5q-, -7/7q-, -17/der(17p) or der(3q) was significantly lower than that without these abnormalities (4.1 months vs 10.1 months,P<0.05). There was no significant difference in the overall survival rate between triploid/tetraploid acute myeloid leukemia (TT-AML) patients and HH-AML patients (8.4 months vs 7.2 months,P>0.05). The overall survival rate of the patients with allogeneic hematopoietic stem cell transplantation was significantly longer than that with chemotherapy alone (25.4 months vs 4.1 months,P<0.01).
Conclusion
HH/TT AML patients are highly heterogeneous. The identification of poor prognosis-related chromosome abnormalities is helpful for the stratification of prognosis. The overall survival time of these patients is short. Early allogeneic hematopoietic stem cell transplantation after remission by combination chemotherapy can significantly improve the prognosis of these patients.

They were assigned to treatment group(n=69), positive control group(n=16), and negative control group(n=30) according to different treatment plan designed in advance. Patients in the treatment group were treated with TCM of "Bushen Huoxue" recipe once a day, with the formula mixed with astragalus 40 g, rehmannia 12 g, cornus 12 g, deerhorn glue melting by heat 12 g, atractylodes 20 g, radix paeoniae alba 20 g, curculigo orchioides 10 g, herba epimedii 10 g, cistanche 12 g, cassia stem 10 g, dried orange peel 8 g, poria 10, gingembre 6 g, angelica sinensis 20 g, salvia miltiorrhiza 20 g, zedoary 9 g, leonurus 30 g, gromwell 15 g, and prepared liquorice root 6 g. Patients in positive control group were treated with desferrioxamine for more than 8 h per day, 5 to 7 days per week. Patients in negative control group were treated with basic treatment.The serum ferritin (SF) and cytokines of patients of the three groups before and 3 months after therapy were detected according to the blood-stasis of TCM symptom rating scale, and the correlation between the decrease of ferritin after treatment and the improvement of blood stasis syndrome score was analyzed. 【Results】 The level of SF of the treatment group, positive and negative control group before treatment were 1 881.63±1 386.81 vs 6 581.36±5 180.96 vs1 974.25±1 753.06, and were 2 040.14±1 484.27 vs 4 169.18±3 631.64(P<0.05)vs 2 699.80±2 352.34(P<0.05) 3 months after treatment. The treatment was effctive in 16 patients in treatment group, accounted for 23.19%(16/69). The score of blood stasis syndrome of the three groups before and after treatment were 4.26±1.45vs 6.88±1.31 vs 4.17±1.18 and 4.42±1.43 vs 5.00±0.89 vs 4.67±1.51(P<0.01), respectively. The effective rate of improving blood stasis syndrome score in the treatment group was up to 26.09%. The decrease of serum ferritin was positively correlated with the improvement of blood stasis score (P < 0.01). The levels of IL-6 and IL-10 in treatment group were 20.79±14.14 and 56.27±25.54 before treatment, 13.00±6.48 and 41.02±9.93(P<0.05)3 months after treatment, respectively. 【Conclusion】 "Bushen Huoxue" therapy can stabilize the the level of SF and improve the blood stasis syndrome in CAA patients with iron overload.

Prediction of the interactions between small molecules and their targets play important roles in various applications of drug development, such as lead discovery, drug repurposing and elucidation of potential drug side effects. Therefore, a variety of machine learning-based models have been developed to predict these interactions. In this study, a model called auxiliary multi-task graph isomorphism network with uncertainty weighting (AMGU) was developed to predict the inhibitory activities of small molecules against 204 different kinases based on the multi-task Graph Isomorphism Network (MT-GIN) with the auxiliary learning and uncertainty weighting strategy. The calculation results illustrate that the AMGU model outperformed the descriptor-based models and state-of-the-art graph neural networks (GNN) models on the internal test set. Furthermore, it also exhibited much better performance on two external test sets, suggesting that the AMGU model has enhanced generalizability due to its great transfer learning capacity. Then, a naïve model-agnostic interpretable method for GNN called edges masking was devised to explain the underlying predictive mechanisms, and the consistency of the interpretability results for 5 typical epidermal growth factor receptor (EGFR) inhibitors with their structure‒activity relationships could be observed. Finally, a free online web server called KIP was developed to predict the kinome-wide polypharmacology effects of small molecules (http://cadd.zju.edu.cn/kip).
