ABSTRACT

ObjectiveTo investigate the role of proinflammatory cytokines tumor necrosis factor alpha (TNFα) and interleukin-1β (IL-1β) in rostral ventromedial medulla (RVM) in chronic postsurgical pain (CPSP) induced by skin/muscle incision and retraction (SMIR). MethodsSD rats were randomly divided into 5 groups: ① Sham group; ② SMIR group; ③ SMIR+TNFα/IL-1β neutralizing antibody group; ④ SMIR+TNFα/IL-1β group and ⑤ SMIR+vehicle group. 50% paw mechanical withdrawal threshold (MWT) was measured by the up-down method, immunofluroscence was used to detect the TNFα and IL-1β expression and ELISA for the 5-Hydroxytryptamine (5-HT) level. ResultsSMIR elicited persistent nociceptive sensitization, upregulated TNFα and IL-1β expression in RVM neurons and astrocytes. Microinjection of TNFα or IL-1β neutralizing antibody into RVM inhibited the development of nociceptive sensitization and decreased the level of 5-HT in both RVM and spinal dorsal horn. While microinjection of recombinant TNFα or IL-1β into RVM enhanced the development of nociceptive sensitization and increased the level of 5-HT in both RVM and spinal dorsal horn. ConclusionUp-regulation of proinflammatory cytokines in RVM may contribute to SMIR induced CPSP by promoting 5-HT release.

ABSTRACT

This article analyzes the limitations of traditional medical theory teaching, and proposes the strategies for cultivating medical students' autonomous learning ability, i.e., informatization-based flipped classroom, problem-oriented teaching, mind mapping training, semi-open book examination, exploitation of the clinical and scientific thinking, and practice activities of medical humanities. The strategies of "problem oriented teaching" and "mind mapping training" were integrated into the practice teaching of hematology. Compared with the traditional medical teaching mode, students' feedback after class showed that the teaching mode incorporating new cultivation strategies was more conducive to the improvement of students' self-learning ability ( P = 0.008), and their satisfaction with teaching mode, learning interest, and self-learning ability were all improved. Thus, the appropriate application of the above strategies can help improve students' autonomous learning ability and optimize the effect of medical theory teaching.

ABSTRACT

Diabetic kidney disease (DKD) is characterized by the hyperfiltration and albuminuria in the early phase which are followed by progressive renal function decline, renal tubular epithelial cell hypertrophy, and tubulointerstitial fibrosis. Thus, it is one of the leading causes of chronic kidney diseases. The currently available therapies mainly aim to control the primary diseases and reduce the risk of kidney injury. Based on syndrome differentiation, traditional Chinese medicine (TCM) relieves the symptoms by excreting water and alleviating edema and eliminates the root cause by tonifying deficiency and supplementing the original Qi, thereby showing therapeutic effect and delaying the progression of DKD. It excels in comprehensively regulating the constitution of patients with little side effects. Among the Zang-fu organs, kidney takes the second place in the content of mitochondria which participate in the metabolism of water and fluid and are the foundation of kidney Yin and kidney Yang. Mitochondria are energy producers within a cell, which carry out cellular respiration, produce reactive oxygen species, and generate adenosine triphosphate by oxidative phosphorylation. Mitochondrial quality control (MQC) is an effective way to maintain mitochondrial dynamic balance, whose imbalances, such as mitochondrial oxidative stress, mitophagy, mitochondrial dynamic changes, and abnormal calcium regulation, are related to the occurrence and development of DKD. It is generally believed that the destruction of mitochondrial structure in the case of metabolic disorder is the main cause of the disease. In recent years, TCM has attracted the attention of both Chinese and foreign researchers for the unique advantages of treating both symptoms and root cause at the same time and multi-target synergy in the treatment of DKD. However, the specific mechanism is still unclear. It has been frequently verified that mitochondria may be one of the targets of TCM in the treatment of DKD. At the moment, no review on the treatment of DKD by TCM through the intervention of MQC is available. Therefore, this paper aims to summarize the research on TCM treatment of DKD by regulating MQC in the past 10 years, which is expected to provide a new direction for the treatment of DKD by TCM.

ABSTRACT

Objective:To investigate the clinical characteristics and prognosis of acute myeloid leukemia (AML) patients with positive TLS-ERG fusion gene.Methods:The clinical data of 9 AML patients with positive TLS-ERG fusion gene in the First Hospital of Jilin University from June 2013 to August 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:Among 9 patients with positive TLS-ERG fusion gene, there were 5 males and 4 females, with a median age of 16 years old (6-40 years old). Five patients received chemotherapy alone, 3 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT), and 1 patient did not receive systematic treatment. Among 8 patients with systematic treatment, 1 patient had complete remission after the first induction chemotherapy and 5 patients had complete remission after induction therapy. The median overall survival time of 5 patients with chemotherapy alone was 1.5 months (1-11 months), of which 3 patients did not respond to the first course of treatment and died of infection, and 2 patients died after relapse. The median overall survival time of 3 patients with allo-HSCT was 16 months (13-17 months), of which 2 patients died after relapse and 1 patient had sustained molecular complete remission by the end of follow-up.Conclusions:AML with positive TLS-ERG fusion gene has low incidence rate and poor induction efficacy. Hematopoietic stem cell transplantation may partially improve the survival prognosis of patients, but it cannot overcome the adverse effect of positive TLS-ERG fusion gene on prognosis.

ABSTRACT

Objective:To analyze the clinical efficacy and safety of stent implantation combined with drug therapy and drug therapy alone in patients with vertebral artery initial stenosis.Methods:A total of 112 patients with vertebral artery initial stenosis who were treated in Wuzhou Workers′ Hospital from January 2016 to June 2018 were selected and divided into drug group and stent + drug group according to random number table method, with 56 patients in each group. The drug group received drug therapy alone, and stent + drug group received stent implantation combined with drug therapy. The incidence of ischemic events in posterior circulation, the improvement of vascular stenosis rate and the improvement of neurological function injury were observed in the two groups after 12 months of treatment.Results:The success rate in the stent + drug group was 100.0%(56/56). The rate of vascular stenosis in the stent + drug group was lower than that in the drug group: (15.21 ± 3.74)% vs. (18.62 ± 4.27)% ; but the incidence of restenosis was higher than that in the drug group:26.79%(15/56) vs. 7.14%(4/56), the differences were statistically significant ( P<0.05). The total incidence of ischemic events in the posterior circulation after treatment in the stent + drug group was lower than that in the drug group: 8.93%(5/56) vs. 28.57%(16/56), and the difference was statistically significant ( χ2 = 7.092, P = 0.008). After treatment, the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (MRS) in the stent + drug group were lower than those in the drug group: (2.30 ± 0.36) scores vs. (3.75 ± 0.52) scores, (4.11 ± 0.51) scores vs.(6.14 ± 0.57) scores, and the differences were statistically significant ( P<0.05). Conclusions:The application of stent implantation combined with drug regimen in the treatment of patients with vertebral artery initial stenosis can effectively reduce the neurological damage of patients, andimprove the total effective rate, which is conductive to the improvement of patients′ quality of life, but the rate of stent restenosis is high.

ABSTRACT

Objective To explore the efficacy and prognostic factors of chemotherapy regimens including decitabine in treatment of elderly patients newly diagnosed with acute myeloid leukemia (AML). Methods The clinical data of 47 elderly patients newly diagnosed with AML (except M3) who received chemotherapy regimens including decitabine in the First Hospital of Jilin University from February 2013 to November 2017 were retrospectively analyzed, including 11 patients treated with single decitabine and 36 patients treated with decitabine combined with low_dose chemotherapy group. The treatment outcome and the impact of different factors on the prognosis were also analyzed. Results Of 47 patients, there were 15 males and 32 females, and the median age was 65 years old (60-83 years old). The overall response rate of decitabine plus low_dose chemotherapy group for 1 course was higher than that of single decitabine group [80.6% (26/36) vs. 27.3% (3/11), χ 2 = 8.693, P= 0.003], and the former showed less courses to acquire remission than the latter (u= 3.133, P= 0.002); however, there was no significant difference in the median overall survival (OS) time between the two groups (14 months vs. 12 months, P= 0.950). Univariate analysis indicated that the median OS time in the complete remission (CR) group was longer than that in the non_CR group (17 months vs. 5 months, P <0.01). The median OS time of the elderly patients with primary AML was longer than that of the patients with secondary AML (16 months vs. 6 months, P= 0.01). Cox multifactor analysis showed that failing to achieve CR was identified as an independent adverse influencing factor ( HR=0.180, 95% CI 0.085-0.382, P< 0.01). The incidence of neutropenia with fever in the patients treated with decitabine plus low_dose chemotherapy group was higher than that in single decitabine group [69.4% (25/36) vs. 36.4% (4/11), χ2=3.902, P=0.048]. Conclusion For newly elderly AML patients, chemotherapy regimens including decitabine are safe and effective.

ABSTRACT

FYVE and coiled-coil domain containing 1(FYCO1) is an adaptor of cellular autophagy which has RUN domain,coiled coil domain,FYVE domain,GOLD domain and LIR domain. FYCO1 protein is widely expressed and mainly interacts with Atg8 family proteins,microtubule-based kinesins,phosphatidylinositol-3-phosphate (PI3P). The FYCO1 protein involved in the movement of kinesins along microtubules and the microtubule plus end-directed transport of autophagy vesicles and related to the development and transparency maintenance of human lens. FYCO1 mutations are one of the causes inducing autosomal recessive congenital cataract. Mutations of FYCO1 can inhibit the process of autophagosome transport to lysosomes,leading to the failure of mitochondrial and other organelle degradation processes in lens fibroblasts and causing opacity of the lens. Eighteen cataract-related mutations have been identified in FYCO1 currently. In addition,FYCO1 protein plays an important role in life processes,such as cell division,and is associated with various diseases,such as Parkinson's disease,cancer,sporadic inclusion body myositis and keloid. This article reviewed the current research progress of FYCO1 gene mutations.

ABSTRACT

Objective To investigate the regulatory role of cathepsin D (CatD) in the degradation of intracellular advanced glycation end products (AGEs) endocytosed by human dermal fibroblasts (HDFs).Methods Cultured HDFs were treated with 1 μnol/L CA074Me (an inhibitor of CatB and CatL),75 μmol/L pepstatin A (an inhibitor of CatD) and 1 μmol/L MG-132 (an inhibitor of20S proteasome) separately for 4 hours,and then cell counting kit 8 (CCKS) assay and fluorometric assay were performed to determine the cellular viability and protease activity,respectively.The cells in the CA074Me group,pepstatin A group and MG-132 group were additionally treated with AGE-bovine serum albumin (BSA) for 8 hours,and the cells in the blank control group were treated with phosphate-buffered saline (PBS) alone.After 8-hour cultivation,the cells in the above groups were subsequently reincubated with fresh culture medium containing the corresponding inhibitors for 24 hours.Then,flow cytometry was performed to assess the mean fluorescence intensity of intracellular AGE-BSA at different time points.Some other HDFs were treated with 37.5,75 and 150 μmol/L pepstatin A and PBS separately for 4 hours,and then the cells in the 4 groups were treated with 200 mg/L AGE-BSA for 8 hours,followed by the removal of AGE-BSA from the medium and the treatment with 37.5,75 and 150 μmol/L pepstatin A and PBS respectively.Enzyme-linked immunosorbent assay (ELISA) was conducted to measure the mean concentration of intracellular AGE-BSA at different time points,and the degradation rate of AGE was calculated.Some HDFs were divided into 3 groups:blank control group receiving no treatment,NC group transfected with an empty vector,and CatD group transfected with a CatD-overexpressing lentiviral vector.Fluorescence microscopy was conducted to estimate the transfection efficiency.Reverse transcription-PCR,Western blot analysis and fluorometric assay were performed to determine the mRNA and protein expression,and activity of CatD respectively.Then,the cells in the above 3 groups were incubated with AGE-BSA for 8 hours,followed by the removal of AGE-BSA from the medium and the treatment with fresh culture medium.The detection methods were same as the above experiment,and the degradation rate was calculated.Results The cellular proliferative activity in the 1-μmol/L CA074Me group,75-μmnol/L pepstatin A group and 1-μ mol/L MG-132 group was more than 90%,and there was no significant difference between the 3 groups and the control group (100%,F =1.525,P > 0.05).Twenty-four hours after the removal of AGE-BSA from the medium,the fluorescence intensities of intracellular AGE-BSA in the CA074Me + AGE-BSA group (275.00 ± 10.15) and MG-132 + AGE-BSA group (259.00 ± 11.14) significantly decreased compared with those at the 8-hour time point (295.00 ± 6.56 and 285.67±8.74 respectively;paired t test,t =4.778,6.154 respectively,both P < 0.05),while no significant difference was observed in the fluorescence intensities of intracellular AGE-BSA in the pepstatin A + AGE-BSA group between the 8-hour time point and 32-hour time point (P > 0.05).The degradation rates of intracellular AGE-BSA within 24 hours in the 37.5,75 and 150 μmol/L pepstatin A groups were 9.64% ± 1.27%,5.62% ± 0.47% and 3.21% ± 0.73% respectively;there were significant differences among the 3 groups (F =45.876,P < 0.05),and the degradation rate significantly decreased along with the increase of pepstatin A concentration (P < 0.05).Fluorescence microscopy showed no fluorescent cells in the blank control group,while the NC group and CatD group both showed a high proportion (> 80%) of fluorescent cells.The mRNA and protein expression as well as the activity of CatD were significantly higher in the CatD group than in the blank control group and NC group (all P < 0.05).The CatD + AGE-BSA group showed a significantly higher degradation rate of intracellular AGE-BSA within 24 hours compared with the AGE-BSA group and NC + AGE-BSA group (both P < 0.05).Conclusion CatD can promote the degradation of intracellular AGE-BSA endocytosed by HDFs.

ABSTRACT

Objective To determine the expression of cathepsin D and advanced glycation end products (AGEs)in skin tissues from patients of different ages or skin tissues with different degrees of sun exposure,to evaluate their correlation,and to preliminarily investigate the role of cathepsin D in the degradation and accumulation of AGEs in photoaged skin.Methods Skin tissues were collected from sunexposed and sun-protected body sites in patients aged 15-20 years,35-40 years,55-60 years or 75-80 years.These skin tissues were divided into 8 groups according to age of patients and degrees of sun exposure,and there were 6 specimens in each group.Immunohistochemical and immunofluorescent methods were used to measure the expression of cathepsin D and AGEs in the skin tissues.Statistical analysis was carried out by factorial design analysis of variance,Wilcoxon rank sum test and Kruskal-Wallis rank sum test for analyzing associations of the expression of cathepsin D and AGEs with age and sun exposure,as well as by Pearson correlation analysis for assessing the correlation between cathepsin D expression and AGEs expression.Results Immunohistochemical study showed that the expression of cathepsin D markedly decreased along with the increase of age,but the accumulation of AGEs gradually increased along with the increase of age.In the same age group,the cathepsin D expression was lower in the sun-exposed skin tissues than in the sun-protected skin tissues,while the accumulation of AGEs was more in the sun-exposed skin tissues than in the sun-protected skin tissues.Factorial design analysis of variance showed that sun exposure could decrease the expression of cathepsin D (F =58.70,P < 0.001),but increase the accumulation of AGEs (F =158.18,P < 0.001).Moreover,the increase of age could lead to decreased expression of cathepsin D (F =79.49,P < 0.001),and increased expression of AGEs (F =106.06,P <0.001).Compared with the sun-protected skin tissues,the sun-exposed skin tissues in all the age groups showed significantly lower absorbance value of cathepsin D (35-40 years:0.020 ± 0.005 vs.0.032 ± 0.005;55-60 years:0.012 ± 0.004 vs.0.026 ± 0.002;75-80 years:0.002 ± 0.001 vs.0.013 ± 0.004;all P <0.001),but higher absorbance value of AGEs (35-40 years:0.030 ± 0.008 vs.0.010 ± 0.003;55-60years:0.066 ± 0.010 vs.0.021 ± 0.004;75-80 years:0.085 ± 0.015 vs.0.035 ± 0.009;all P < 0.001)except the age group of 15-20 years.No matter whether the skin tissues were sun-exposed or sunprotected,there were significant differences in the expression of cathepsin D and AGEs among different age groups (all P < 0.001).The results of double immunofluorescence staining were similar to those of immunohistochemical study.Pearson correlation analysis showed that the expression of cathepsin D in the sun-exposed skin tissues was highly negatively correlated with the accumulation of AGEs (r =-0.915,P <0.05),while they were moderately negatively correlated in the sun-protected skin tissues (r =-0.730,P <0.05).Conclusions Along with the increase of age,the expression of cathepsin D in skin tissues decreased,but the expression of AGEs increased.In the sun-protected skin tissues,the expression of cathepsin D was moderately negatively correlated with the expression of AGEs,while they were highly negatively correlated in the sun-exposed skin tissues,suggesting that cathepsin D may play an important role in the degradation and accumulation of AGEs in photoaged skin.

ABSTRACT

Objective To evaluate the effect of photoaging on the degradation of advanced glycation end products (AGEs) by human dermal fibroblasts.Methods Some cultured human dermal fibroblasts were subjected to repetitive ultraviolet A (UVA) radiation (UVA radiation group) to establish a photoaging cell model,which was then evaluated by cell counting kit 8 (CCK-8) assay,senescenceassociated β-galactosidase staining and detection of apoptosis rate.Moreover,fibroblasts receiving no treatment served as control group.Some other primary fibroblasts were divided into 4 groups:photoaged group receiving UVA radiation,non-photoaged group receiving no treatment,AGE-treated photoaged group treated with UVA radiation followed by the treatment with 200 mg/L AGE-bovine serum albumin (BSA),and AGE-treated non-photoaged group treated with 200 mg/L AGE-BSA alone.After the treatment with AGE-BSA for 4-72 hours,flow cytometry was performed to determine the fluorescence intensity of AGE-BSA in fibroblasts of the above groups.After 8-hour treatment with AGE-BSA,confocal laser scanning microscopy was performed to localize and semiquantitatively detect AGE-BSA in fibroblasts,and enzymelinked immunosorbent assay (ELISA) was conducted to detect AGE-BSA levels in fibroblasts,as well as changes in the intracellular AGE-BSA level within 24 hours after the removal of AGE-BSA.Results Compared with the control group,the UVA radiation group showed significantly decreased cellular proliferative activity (t =7.559,P < 0.05),but significantly increased apoptosis rate and percentage of β-galactosidase-positive fibroblasts (t =14.075,43.524 respectively,both P < 0.05).Flow cytometry revealed that the average fluorescence intensities of AGE-BSA after 4-,8-,16-,24-,48-and 72-hour treatment with AGE-BSA were significantly higher in the AGE-treated photoaged group (293.00 ± 8.19,359.67 ± 11.59,347.00 ± 12.29,338.00 ± 12.77,334.67 ± 14.22 and 336.30 ± 10.21,respectively) than in the photoaged group (all P < 0.05),as well as in the AGE-treated non-photoaged group (222.33 ± 8.74,276.33 ± 6.11,256.33 ± 5.51,243.00 ± 10.15,236.33 ± 1.53 and 240.33 ± 1.52,respectively) than in the non-photoaged group (all P < 0.05).Moreover,the average fluorescence intensities of AGE-BSA at different time points were all significantly higher in the AGE-treated photoaged group than in the AGE-treated non-photoaged group (all P < 0.05).Confocal laser scanning microscopy showed that AGE-BSA was mainly localized in lysosomes after endocytic uptake into the fibroblasts,and the AGE-treated photoaged group showed significantly increased fluorescence intensity of AGE-BSA compared with the AGE-treated non-photoaged group (P < 0.05).ELISA revealed that the intracellular AGE level in the AGE-treated non-photoaged group at 24 hours after the removal of AGE-BSA was decreased by (14.6 ± 1.2)% compared with that before the removal,and the degradation rate of AGE-BSA was significantly higher in the AGE-treated non-photoaged group than in the AGE-treated photoaged group (7.6% ± 1.4%,t =6.604,P < 0.05).Conclusion The internalized AGE-degradating ability decreases in photoaged fibroblasts,which may induce the accumulation of AGEs in photoaged skin.
