ABSTRACT

Acute leukemia (AL) is a kind of malignant clonal disease of hematopoietic stem cells. Rearrangement of mixed lineage leukemia (MLL) gene can be observed in about 5%-10% of AL patients. Currently, AL patients with MLL-rearrangements (MLL-r) lack effective treatment and are usually associated with poor prognoses. Recent studies have shown that many epigenetic regulators are directly or indirectly involved in the occurrence and development of AL carrying MLL-r (MLL), which provides a biological basis for the use of epigenetic regulation strategies to treat MLL. In this review, we start from the epigenetic regulation mechanism of MLL, and select representative drug targets to briefly analyze the relationship between each target and MLL and summarize the development progress of their inhibitors, hoping to provide reference for the subsequent research and development of drugs for the treatment of MLL.

ABSTRACT

Cyclic peptide drugs have gradually become an emerging research direction due to their some favorable properties such as high-efficiency binding affinity, high selectivity, lower toxicity, and stable metabolism. In recent years, the number of cyclic peptide drugs under clinical research has continued to increase. Unlike the previous cyclic peptide drugs, which were mostly derived from natural products and their derivatives, these cyclic peptide drugs are designed by genetically encoded display technologies which are based on rational design and in vitro evolution (such as BT1718, PTG-300, POL6326, etc). Among them, phage display technology has some advantages such as mature research system, low cost, and simpler operation that make it well recognized and praised by the majority of researchers in this field. Here, we reviewed the recent progress of applying phage display technology to explore diverse cyclic peptide libraries, which, we believe, will contribute more valuable candidate cyclic peptide drugs in clinical research.

ABSTRACT

Objective:To recognize the characteristics of necrotizing fasciitis patients complicated with sepsis and summarize the experience the treatment.Methods:A retrospective study was conducted. The clinical data of 57 patients with necrotizing fasciitis complicated with sepsis admitted to Guangdong Provincial People's Hospital from July 2009 to December 2019 was analyzed by collecting such factors as gender, age, complications, infection sites, pathogens, surgery information, treatment options and outcome. The patients were divided into debridement group ( n = 14) and control group ( n = 43) according to whether the debridement was completed within 48 hours of admission, and the mortality during hospitalization between the two groups was compared. A telephone follow-up had been done to record the long-term outcome of these patients. Results:Among 57 patients with necrotizing fasciitis complicated with sepsis, there were 43 males and 14 females with the average age of (57.9±12.1) years old. Most of the underlying diseases were diabetes mellitus (70.17%), other diseases included hypertension (8.77%), tumor chemotherapy (7.02%), liver disease (hepatitis, cirrhosis, 7.02%), coronary artery heart disease (3.51%), systemic lupus erythematosus (3.51%), etc. Most of the infection site was lower limbs (71.93%). There were 78 pathogens cultured in 57 patients, in which 52 were non-drug resistant bacteria (66.67%), and 26 were drug resistant bacteria (33.33%). There were 40 Gram positive (G +) bacteria (51.28%), 29 Gram negative (G -) bacteria (37.18%), 8 fungi (10.26%) and 1 mixed bacteria (1.28%). Finally, of 57 patients, 46 patients were cured, and 11 patients died with hospital mortality of 19.30%. Among 57 patients, the hospital mortality in the debridement group was significantly lower than that in the control group [0% (0/14) vs. 25.58% (11/43), P < 0.05]. Among the 46 cured patients, 11 had accepted amputations, accounting for 23.91%. In December 2020, 43 patients who were cured (3 patients were lost to follow-up) were followed up by telephone. Twenty-three patients were completely self-care, 9 patients were partly self-care, 8 patients were completely unable to take care of themselves, and 3 patients died. Conclusions:Necrotizing fasciitis with sepsis mostly occurs in people with weakened immunity, and has a high mortality and disability rate. Early identification and active surgical debridement may be the key to improve the treatment effect.

ABSTRACT

BACKGROUND: The formation of bacterial biofilm on the material surface is the core problem of catheter-related urinary tract infection. Many researches have focused on the mechanism and prevention of such category of infection under static or simple hydrodynamic stimulation. The construction of dynamic model of bacterial biofilm of bladder urine flow close to real human diseases is the key to study the pathological mechanism and develop new technology of anti-biofilm infection. OBJECTIVE: To put forward the concept of turbulent flow shear stress of human bladder urine flow, construct this turbulent shear stress system based on the bacterial biofilm reactor of in vitro bionic human bladder, and explore the formation of E. coli biofilm stimulated by different stresses. METHODS: An in vitro dynamic bionic bladder urine flow model was designed. E. coli standard strain ATCC25922 was used as research object, and the medical silica gel was used as bacterial biofilm forming carrier. Four artificial urine flow stresses were simulated: hydrostatic pressure, constant turbulent flow shear stress, physiological turbulent flow shear stress and pathological turbulent flow shear stress (simulated urine retention environment). A bacterial biofilm reactor loaded with turbulent flow shear stress was established. Optical density value, colony count, and biofilm surface area of bacterial biofilm suspension were detected 24, 72, 120, and 168 hours. RESULTS AND CONCLUSION: (1) Optical density value of bacterial membrane suspension: there was significant difference between different urinary stress groups and different test time points (F=110.84, 187.96, all P < 0.000 1), and there was interaction effect between time and stress (F=50.05, P < 0.000 1). From hydrostatic pressure, constant turbulent flow shear stress, physiological turbulent flow shear stress, to pathological turbulent flow shear stress, the number of biofilm bacterial colonies increased. (2) Colony count of biofilm bacterial suspension smear: there was significant difference between different time (F=6.30, P=0.002 9); no difference was found between different urinary stress groups (F=1.11, P=0.400 1); and there was no interaction effect between time and stress (F=0.85, P=0.581 4). However, with the time extension of stress action, the colony count of complex stress group showed an increasing tendency, especially in the pathological turbulent shear stress. (3) Scanning electron microscopic characterization of biofilm bacteria: qualitative comparison between each group and different time points showed that the formation of bacterial biofilm was different from sparse fragments, lumps to large lumps. There were significant differences in the bacterial biofilm surface area between different urinary stress groups and at different times (F=505.72, 1 201.84, all P < 0.000 1), and there was interaction effect between time and stress (F=78.14, P < 0.000 1). From hydrostatic pressure, constant turbulent flow shear stress, physiological turbulent flow shear stress, to pathological turbulent flow shear stress, the biofilm formation increased significantly. (4) The results showed that this turbulent flow shear stress of human bladder urine flow can obviously stimulate E. coli biofilm formation in vitro. Its functional changes and pathogenic mechanism need to be further explored.

ABSTRACT

To investigate the effect of venous super drainage applying in free flaps. Methods From June, 2017 to December, 2018, 7 cases who had severe soft tissue injuries were treated with free flap. Cause of injury: 1 electric injuries, 2 tumor-related wounds, 1 deep burns, 2 mechanical trauma, and 1 necrotizing fasciitis. All patients were underwent free flap transplantation. There were 5 cases of anterolateral thigh artery perforator flap, 1 case of superficial circumflex iliac artery perforator flap, and 1 case of first dorsal metatarsal artery perforator flap.The application of venous super-drainage technology was carried out according to needs and specific conditions. Two sets of venous passages were prepared in both recipient and donor site to form a double set of venous reflux super-drainage mode. Blood supply, swelling, exudation, secondary exploration and survival rate of the flap were observed after operation, and regularly followed-up. Results All 7 flaps survived. Venous super drainage technique was ap-plied in 7 cases. No arteriovenous crisis occurred after the operation. The flaps had good blood circulation, slight swelling, less exudation, rapid edema regression and no secondary surgical exploration. Followed-up for 2-18 (average 10.5) months, there was no infection recurred. Flaps survived well, and the donor sites healed well without sensory loss.The flexion and extension function of joint was normal. Conclusion The technique of venous super-drainage prepares 2 sets of venous systems for the free flap in the treatment of vascular pedicle in the free flap repair operation, which is conducive to reducing the venous crisis after flap surgery, reducing flap edema, reducing exudation, reducing secondary surgical exploration and improving the survival rate of the flap.

ABSTRACT

Genomic alterations are commonly found in the signaling pathways of fibroblast growth factor receptors (FGFRs). Although there is no selective FGFR inhibitors in market, several promising inhibitors have been investigated in clinical trials, and showed encouraging efficacies in patients. By designing a hybrid between the FGFR-selectivity-enhancing motif dimethoxybenzene group and our previously identified novel scaffold, we discovered a new series of potent FGFR inhibitors, with the best one showing sub-nanomolar enzymatic activity. After several round of optimization and with the solved crystal structure, detailed structure-activity relationship was elaborated. Together with metabolic stability tests and pharmacokinetic profiling, a representative compound () was selected and tested in xenograft mouse model, and the result demonstrated that inhibitor was effective against tumors with FGFR genetic alterations, exhibiting potential for further development.

ABSTRACT

Objective To find late diagnosis and its influencing factors of newly reported HIV/AIDS in Guizhou Province from 2014 to 2018. Methods Through the Chinese National Comprehensive HIV/AIDS Prevention and Care Information System,all newly reported HIV/AIDS cases from 2014 to 2018 in Guizhou Province were analyzed and related factors of late diagnosis were analyzed using binary Logistic regression model. Results From 2014 to 2018, there were 33 611 newly reported HIV/AIDS cases in Guizhou Province, and the late diagnosis rates of newly reported cases were 35.46%, 34.49%, 38.35%, 39.74% and 38.80% respectively. The analysis showed that the proportion of late diagnosis cases from medical institutions increased year by year ( 2=64.603,P<0.001). By analyzing the late diagnosis rate of cases from different sample sources, medical institutions was significantly higher than that reported by voluntary counseling and testing, positive spouses or sexual partners( 2=276.033,P<0.001). Multivariate analysis showed that gender, marital status, route of transmission, occupation, ethnicity and source of samples were associated with the late diagnosis of newly reported cases (all P<0.05). Conclusions It shows a slow upward trend of late diagnosis rate among HIV/AIDS reported in Guizhou Province from 2014 to 2018.On the one hand, it is of great significance to continue to strengthen the publicity and education of the whole population in Guizhou , in order to improve the awareness of HIV active detection. On the other hand, we should continue to expand HIV testing in Guizhou Province to improve the early detection level of HIV/AIDS.

ABSTRACT

Objective@#To understand the mortality and influencing factors on injecting drug users (IDUs) with HIV/AIDS, in Guizhou province, 1996-2015.@*Methods@#A retrospective cohort study was conducted on IDUs with HIV/AIDS that were reported through national comprehensive HIV/AIDS information system, in Guizhou province during 1996-2015. Cox proportional hazard regression model was used to analyze the influencing factors on the mortality of HIV/AIDS.@*Results@#A total of 3 958 cases of IDUs with HIV/AIDS were recruited in this study, with all-cause mortality rate of 44.01% (1 742/3 958) and total mortality rate of 7.80/100 person-years, respectively. The median survival time between diagnosis and death was 8.08 years. Mortality rate was 3.57/100 person-years in the group receiving antiretroviral therapy (ART). The mortality appeared to be 4.08/100 person-years in the group who were on methadone maintenance treatment (MMT). Data from the multiple regression analysis indicated that factors of gender, ethnicity, age when HIV/AIDS diagnosis was made, CD4+T lymphocyte (CD4) count at the first testing, ART and MMT were significantly associated with deaths among these people. The risk of death in females was 0.82 times (95%CI: 0.69-0.98) higher than that in males. The risk of deaths among the ethnic minority subjects was 1.39 times (95%CI: 1.21-1.60) higher than that of the Hans. The risk of death appeared to be 2.44 times higher (95%CI: 1.07-5.56) in the over-50-year of age group than in the <20 year-old group, when HIV/AIDS was diagnosed for the first time. The risk of death in CD4 ≥500/μl group in the first time was 0.27 times (95%CI: 0.22-0.32) more than CD4 <200/μl group in the firs time. The risk of death in cases who were treated with ART or MMT was 2.83 times (95%CI: 2.45-3.26) and 1.35 times (95%CI: 1.15-1.59) higher than those who did not receive any treatment, respectively.@*Conclusion@#Higher risks on death seemed to be related to the following factors: being male, older age at the time of diagnosis, lower CD4 at diagnosis, not on ART or MMT among the IDUs with HIV/AIDS in Guizhou province, between 1996-2015.

ABSTRACT

Bromodomain-containing proteins (BCPs) can specifically recognize acetylated lysine (KAc) in histones and other substrate proteins. Recently, several kinase inhibitors were found to inhibit bromodomains, such as the PLK1 inhibitor BI-2536 and the JAK2 inhibitor TG101209, which bind to BRD4 with IC50 values of 25 nmol·L-1 and 130 nmol·L-1, respectively. To obtain potent BRD4 inhibitors from inhibitor BI-2536, we used dihydroquinoxalin-2(1H)-one to replace the 7,8-dihydropteridin-6(5H)-one in BI2536. By exploring the structure-activity relationships of the new dihydroquinoxalin-2(1H)-one structures, we obtained a novel phenyl side chain series of BRD4 inhibitors. We identified several potent BRD4 inhibitors, especially compounds 16, 22, 28 and 29, which had IC50 values below 100 nmol·L-1 in fluorescence anisotropy (FA) assays, indicating this series of compounds are worth to fruther investigation.

ABSTRACT

Objective@#To explore the effects of allogeneic bone marrow mesenchymal stem cells (BMSCs) on polarization of peritoneal macrophages isolated from rats with sepsis induced by endotoxin/lipopolysaccharide (LPS).@*Methods@#(1) BMSCs were isolated, cultured and purified from 5 SD rats with whole bone marrow adherent method. The third passage of cells were collected for morphologic observation, detection of expressions of stem cell surface markers CD29, CD44, CD45, and CD90 with flow cytometer, and identification of osteogenic and adipogenic differentiation. (2) Another 45 SD rats were divided into sham injury group (SI, n=5), LPS control group (LC, n=20), and BMSCs-treated group (BT, n=20) according to the random number table. Rats in groups LC and BT were injected with LPS (5 mg/kg) via tail vein to induce sepsis; rats in group SI were injected with the same amount of normal saline to simulate the damage. At post injury hour (PIH) 1, rats in group BT were given 1 mL BMSCs (2×106/mL) via tail vein injection; rats in another two groups were injected with equal volume of phosphate buffer saline. Five rats in group SI at PIH 24 and in groups LC and BT at PIH 6, 12, 24, and 48 were sacrificed to harvest lung tissue for pathological observation with HE staining. In addition, rats in group SI at PIH 24 and in groups LC and BT at PIH 24 and 48 were simultaneously performed with intraperitoneal injection of low-glucose DMEM. Then peritoneal fluid was harvested to culture peritoneal macrophages. Flow cytometer was used to assess the positive expression of cell makers of macrophages including CD68 (making gate), CD11c, and CD206 in group SI at PIH 24 and in groups LC and BT at PIH 24 and 48. Data were processed with one-way analysis of variance and LSD test.@*Results@#(1) The third passage of cells showed uniform fiber-like shape similar to fibroblasts. These cells showed positive expressions of CD29, CD44, CD90 and weak positive expression of CD45. They were able to differentiate into osteoblasts and adipocytes. These cells were identified as BMSCs. (2) At PIH 24, the structure of pulmonary alveoli of rats in group SI was clear and complete with no congestion or inflammatory cell infiltration. At PIH 6, the structure of pulmonary alveoli of rats in groups LC and BT was clear with a small amount of inflammatory cell infiltration, slight congestion and pulmonary interstitial thickening. At PIH 12, the inflammatory responses in lung tissue of rats in group LC were more severe than those in group BT with a large amount of inflammatory cell infiltration, serious congestion, and obvious pulmonary interstitial thickening. The pathological results of rats in group BT at PIH 12 was consistent with the results at PIH 6. At PIH 24, the pathological results of rats in groups LC and BT were similar to the results at PIH 12. At PIH 48, the structure of pulmonary alveoli tissue of rats in group LC was still severely disrupted, with a large number of inflammatory cell infiltration and congestion in lung tissue, but pulmonary interstitial thickening was slightly alleviated than before. The condition of rats in group BT nearly recovered to that in group SI. (3) At PIH 24, the positive expression rate of CD11c in peritoneal macrophages of rats in group LC [(83±10)%] was close to that in group BT [(87±7)%, P>0.05], and they were both significantly higher than the rate in group SI [(55±12)%, with P values below 0.01]. The positive expression rate of CD11c in peritoneal macrophages of rats in group LC [(59±11)%] at PIH 48 was close to that in group SI at PIH 24 (P>0.05), and they were both significantly higher than the rate in group BT [(20±11)%] at PIH 48 (with P values below 0.01). At PIH 24, the positive expression percentages of CD206 in peritoneal macrophages of rats were similar among the three groups (with P values above 0.05). The positive expression percentage of CD206 in peritoneal macrophages of rats in group SI at PIH 24 was close to that in group BT at PIH 48 (P>0.05), and they were both significantly lower than the percentage in group LC at PIH 48 (with P values below 0.01).@*Conclusions@#BMSCs can reduce the pathological inflammatory responses in the lung of rats with sepsis and inhibit peritoneal macrophages from polarizing into M1 phenotype, whereas they can not promote macrophages to polarize into M2 phenotype.

ABSTRACT

Objective To investigate the potential protective effects of valproic acid (VPA) on gut barrier function after major burn injury in rats and its mechanism.Methods Forty male Sprague-Dawley (SD) rats were divided into sham + normal saline (NS),sham + VPA,scald + NS,and scald + VPA groups,with 10 rats in each group.Rat with 55% total body surface area (TBSA) third-degree severe-bums model was reproduced by immersing into 80 ℃ water,and the rats in sham groups were given sham-bums by immersing into 37 ℃ water.The rats after severebums were immediately treated with 0.25 mL of 300 mg/kg VPA or NS by subcutaneous injection.Rats were sacrificed at 2 hours and 6 hours after injury,and abdominal aortic blood and ileal tissue were harvested.The levels of vascular endothelial growth factor (VEGF) were determined by enzyme-linked immunosorbent assay (ELISA).The intestinal permeability was evaluated by fluorescein isothiocyanate-dextran (FITC-dextran) determination.The histomorphological changes in gut barrier were evaluated by Chiu grading system.Levels of acetylated lysine at the ninth position of histone 3 protein (Ac-H3K9),hypoxia-inducible factor 1α (HIF-1α),zona occludens 1 (ZO-1) and myosin light chain kinase (MLCK) were determined by immunofluorescence staining and Western Blot.Results Compared with sham + NS group,rats in scald + NS group showed intestinal mucosal damage 2 hours after bum injury,as well as increased mucosal permeability,protein expression levels of HIF-1 α,VEGF,MLCK,and lowered levels of AC-H3K9 and ZO-1.These changes were much more prominent at 6 hours after injury.VPA treatment significantly attenuated the bum-induced intestinal damage.Compared with scald + NS group,the protective effects in scald + VPA group was not evident at 2 hours after injury;however,intestinal damage was much less severe at 6 hours after injury (Chiu score:2.03 ± 0.27 vs.3.12 ± 0.15),intestinal permeability was significantly decreased [FITC-dextran (μg/L):709 ± 76 vs.1138 ± 75],histone acetylation was enhanced [Ac-H3K9 (gray value):1.55 ± 0.12 vs.0.48±0.12],ZO-1 degradation was significantly inhibited (gray value:0.69 ± 0.12 vs.0.43 ± 0.16),the protein expression levels of VEGF and MLCK were significantly down-regulated [VEGF (ng/mg):51.7±3.7 vs.71.2±4.3,MLCK (gray value):1.98±0.20 vs.2.80±0.24],while the HIF-1 α protein expression levels were significantly reduced at both 2 hours and 6 hours after injury (gray value:2.50±0.39 vs.3.88±0.42 at 2 hours,1.83±0.42 vs.4.42±0.41 at 6 hours,all P < 0.05).Conclusions Severe bum injury can induce histone deacetylation,ZO-1 degradation and intestinal barrier dysfunction.VPA can improve the levels of histone acetylation and ZO-1,and protect intestinal epithelial barrier function.These may probably be mediated through inhibiting HIF-1α and its downstream gene VEGF and MLCK.

ABSTRACT

Histone acetylation is a critical process in the regulation of chromatin structure and gene expression. Histone deacetylases (HDACs) remove the acetyl group, leading to chromatin condensation and transcriptional repression. HDAC inhibitors are considered a new class of anticancer agents and have been shown to alter gene transcription and exert antitumor effects. This paper describes our work on the structural determination and structure-activity relationship (SAR) optimization of tetrahydroisoquinoline compounds as HDAC inhibitors. These compounds were tested for their ability to inhibit HDAC 1, 3, 6 and for their ability to inhibit the proliferation of a panel of cancer cell lines. Among these, compound 82 showed the greatest inhibitory activity toward HDAC 1, 3, 6 and strongly inhibited growth of the cancer cell lines, with results clearly superior to those of the reference compound, vorinostat (SAHA). Compound 82 increased the acetylation of histones H3, H4 and tubulin in a concentration-dependent manner, suggesting that it is a broad inhibitor of HDACs.

Methods 46 pregnant women with ureteral calculi were selected.All patients were treated by cystoscope indwelling double J tube.Observation indexes were the follow -up complications after a week of operation time,operation situa-tion,Visual analogue scale (VAS)was used to evaluate the degree of pain operation before and after treatment 48 h. To observe the pregnant women with double J tube placement and delivery status.Results 46 patients were success-fully catheter,the average operation time was (29.14 ±3.27)min.37 patients with lumbar cramps and fever and other symptoms were relieved after treatment.6 patients with replacement of double J tube 2 months later.After treatment, VAS score was (1.16 ±0.83)points,which was lower than (6.93 ±1.02)points before treatment,the difference was statistically significant (t =9.64,P <0.05).After treatment,the infection rates of hydronephrosis and urinary tract were 4.35% (2 /46)and 0% (0 /46),which were lower than before treatment [(15 /46,32.61%)and 19.57%(9 /46)],the differences were statistically significant (χ2 =8.33,9.05,all P <0.05);46 cases of pregnant women were smooth production,no abortion complications.The average indwelling double J tube time was (5.08 ± 1.16)months.Conclusion Cystoscope indwelling double J tube for the treatment of ureteral calculi in pregnancy has less invasion,high stone clearance rate,less postoperative complications and high safety,the prognosis was good,and it is a safe and effective method.

ABSTRACT

Objective To explore the prevalence of sialorrhea and its clinical correlation with dysphagia in Chinese patients with Parkinson′s disease ( PD ).Methods One hundred and sixteen consecutive patients with a clinical diagnosis of PD were selected.Demographic data included sex , age, years of education, age at onset of PD, clinical genotype, disease duration, treatment, Hoehn and Yahr (H&Y) stage.Sialorrhea was assessed using the Unified Parkinson′s Disease Rating Scale (UPDRS) Ⅱitem number 6.All patients were studied with videofluoroscopic study of swallowing ( VFSS).Results The prevalence rate of sialorrhea in PD was 59.5% (69/116, 95% CI 50.6%-68.4%).Males were more likely to develop sialorrhea than females (47/70 vs 22/46,χ2 =4.298, P=0.038).PD patients′sialorrhea correlated with oral dysphagia:with food leaking from the mouth ( liquid r=0.229, P=0.014; juice r=0.197, P=0.034;pudding viscosities r=0.231, P=0.013;solid food r=0.255, P=0.006), with more than 1 ml of oral food residues (liquid r=0.319, P<0.01;solid food r=0.185, P=0.047), with delay in food transfer to the root of the tongue (liquid r=0.279, P=0.002; juice r=0.209, P=0.024), and delayed swallow transfer ( pudding viscosities r=0.257, P=0.005).Sialorrhea score was not related to H&Y stage, clinical course and levodopa equivalent doses (LED).The prevalence rate of dysphagia in PD was 87.1%(95% CI 81.0% -93.2%).Liquid was more likely to cause pharyngeal dysphagia ( P=0.03).With the increase in H&Y stage , so did the oral and pharyngeal stages of dysphagia.Late and mid-course was more likely to develop oral and pharyngeal dysphagia than those with early clinical course .Conclusions Sialorrhea and dysphagia are common non-motor symptoms in PD patients.Sialorrhea is more prevalent in males and correlates with oral phase of dysphagia.Liquid is more likely to cause pharyngeal dysphagia.With increase in H&Y stage , so did oral and pharyngeal dysphagia.Even though late clinical course is more likely to develop oral and pharyngeal dysphagia than early clinical course , the comparison between late and intermediate clinical courses does not reach statistical significance .
