ABSTRACT
【Objective】 To analyze the influence of plasma donation on human total protein level and the impact of different blood collection tubes on total protein level detection. 【Methods】 A total of 1 373 plasma donors from 11 apheresis plasma stations in 6 provinces/autonomous regions from March to April, 2021 were selected. Whole blood was collected by ordinary blood collection tube without anticoagulant, heparin anticoagulant tube and sodium citrate anticoagulant tube, and then respectively divided into serum group, heparin anticoagulant group, and sodium citrate anticoagulant group. After separating serum and plasma, the samples were subjected to total protein detection using the biuret method. Kruskal-Wallis test was used to compare the total protein levels among different tubes. The plasma donors were divided into male group (n=597) and female group (n=776), and the total protein levels between different genders were compared by t test. The plasma donors were divided into Sichuan group, Hubei group and Gansu group according to the region, and the Games-Howell test was used for comparison. 【Results】 The median serum total protein level of 1 373 donors was 73.1g/L, which was consistent with the reference range of 65-85 g/L. The median total protein levels of the serum group, heparin anticoagulant group and sodium citrate anticoagulant group were 73.1g/L, 73.3g/L and 63.8g/L, respectively, with statistically significant difference (P 0.05). The serum total protein levels of male group and female group were (72.41±5.40)g/L and (73.67±4.95)g/L, reseectively, and the difference was statistically significant (P0.05). 【Conclusion】 Plasma donors who meet the donation criteria will not experience abnormal total protein levels due to regular plasma donation. There were differences in total protein levels among different blood collection tubes, different genders and different regions. The total protein level of females was higher than that of males. The total protein level was the highest in Hubei province, followed by Sichuan and Gansu.Heparin anticoagulant group was the highest, followed by serum group and sodium citrate anticoagulant group.
ABSTRACT
Purpose To explore the diagnostic value of beak sign in fetal annular pancreas by analyzing the ultrasonographic features of fetal annular pancreas.Materials and Methods The ultrasound images and clinical data of 13 cases of fetal annular pancreas diagnosed by prenatal ultrasound in Shandong Provincial Maternal and Child Health Hospital from September 2019 to December 2021 and confirmed by surgery after birth were retrospectively analyzed.The degree of duodenal stenosis at the obstruction site was observed,especially whether the angle formed by the intestinal wall could identify the fetal annular pancreas,and the ultrasonic characteristics were summarized and analyzed.Results A total of 13 fetuses with annular pancreas showed double bubble sign,3 cases showed clamp sign,and 7 cases showed beak sign at the end of duodenal dilatation.All the 13 cases underwent surgical treatment after birth,including 2 cases with duodenal atresia and 1 case with atypical intestinal malrotation.All the children had good prognosis after operation.Conclusion By observing the dilated end of duodenum and the relationship with pancreatic head,prenatal ultrasound combined with beak sign and double bubble sign could improve the diagnostic accuracy of fetal annular pancreas,which has significant value in prenatal diagnosis of fetal annular pancreas.
ABSTRACT
Objective:To analyze the correlation between the skin temperature changes in the radiation area and the occurrence of radiodermatitis during postoperative radiotherapy for female breast cancer and to explore the application value of skin temperature monitoring in the early warning of radiodermatitis risks.Methods:A total of 103 patients who received three-dimensional conformal radiotherapy after radical mastectomy in the Fourth Hospital of Hebei Medical University were continuously enrolled from May to November, 2022 in this study. Their skin temperature in the radiation area and radiodermatitis were recorded weekly. The relationships between relative skin temperature differences and different grades of radiodermatitis were determined. The optimal cut-off values for grade ≥ radiodermatitis were calculated, and the predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Furthermore, the radiodermatitis risks under different skin temperatures were compared using binary logistic regression.Results:There was a positive correlation between the skin temperature in the radiation field and the grade of radiodermatitis. The optimal cut-off values for the average relative skin temperature difference of the chest wall (under 40 Gy/20 fractions), the maximum relative skin temperature difference of the chest wall (under 40 Gy/20 fractions), and the relative skin temperature difference of the supraclavicular block (under 30 Gy/15 fractions) were 0.45℃, 0.55℃, 0.15℃, respectively. The patients were divided into low- and high-risk groups based on the optimal cut-off values (0.45℃, 0.55℃, and 0.15℃). Binary logistic regression result showed that the risks of grade ≥ 2 radiodermatitis in the high-risk group were 5.71, 4.29, and 5.15 times those in the low-risk group, respectively ( OR = 5.71, 95% CI 1.81-17.99, P = 0.003; OR = 4.29, 95% CI 1.65-11.12, P = 0.003; OR = 5.15, 95% CI 2.16-12.31, P < 0.001). Conclusions:Skin temperature monitoring using medical infrared thermometers can be used to effectively predict the occurrence of grade ≥ 2 radiodermatitis. The skin temperature changes in the radiotherapy area should be closely observed. The risk of grade ≥ 2 radiodermatitis will increase when the mean and maximum relative temperature differences of the chest wall increase by 0.45℃ and 0.55℃, respectively under 40 Gy/20 fractions of radiotherapy or when the relative temperature differences of the supraclavicular block increases by 0.15℃ under 30 Gy/15 fractions of radiotherapy.
ABSTRACT
Objective:To analyze the detection of non-alcoholic fatty liver disease (NAFLD) and the multiple corresponding relationships of its risk factors in a middle-aged and young adult population undergoing health check-ups.Methods:This study was a cross-sectional study conducted on 15 423 individuals aged between 18 and 59 who underwent health check-ups at the Health Management Center of Henan Provincial Hospital of Traditional Chinese Medicine from January to December 2021. Relevant health examination data was collected, including basic information (age, gender, past medical history, smoking and alcohol consumption), physical examination, laboratory indicators such as blood lipids and blood glucose, and abdominal ultrasound results. The chi-square test was used to compare the prevalence of NAFLD among different characteristics of the population, and multiple correspondence analysis was employed for statistical analysis of related influencing factors.Results:A total of 5 859 cases of NAFLD were detected in this study, with a detection rate of 37.99%. The detection rate of NAFLD gradually increased with age ( χ2=828.841, P<0.001) and body mass index (BMI) ( χ2=1 889.809, P<0.001). The detection rates of NAFLD were higher in individuals with hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, low high-density lipoprotein cholesterolemia, high low-density lipoprotein cholesterolemia, and hyperuricemia compared to those without these conditions ( χ2 value was 1 223.673, 364.808, 444.074, 2 436.765, 1 323.736, 591.478, and 943.069, respectively, all P<0.001). Multiple correspondence analysis revealed that NAFLD was closely related to hypertension, hypertriglyceridemia, diabetes, hyperuricemia, overweight, obesity, and the age group of 45-49 years. Correspondence analysis graphs for males and females showed associations between NAFLD and hypertension, hypertriglyceridemia, hyperuricemia, overweight, and obesity. In males, NAFLD was closely related to the age group of 35-49 years, while in females, it was closely associated with the age group of 45-49 years and diabetes. Conclusions:The detection rate of non-alcoholic fatty liver disease is relatively high in middle-aged and young adult populations. Males, those who are overweight or obese, and individuals with hypertension, diabetes, hyperuricemia, or abnormal blood lipids are more susceptible to non-alcoholic fatty liver disease.

ABSTRACT
The clock gene Rev-erbα, also known as nuclear receptor subfamily 1 group D member 1 (Nr1d1), is a crucial regulatory factor in organisms. It exhibits circadian rhythmic expression in metabolically active tissues such as skeletal muscles, heart, liver, and adipose tissue, responding to various environmental stimuli. Rev-erbα plays a significant role in regulating circadian rhythms, metabolic homeostasis, and other physiological processes, earning its designation as an “integrator” of the circadian system and metabolism. Rev-erbα establishes complex connections with other clock genes through the transcriptional-translational feedback loop (TTFL), which is important for the rhythmic output of biological clock system and for the relative stability of phases and cycles. Mitochondrial biogenesis is a physiological process initiated by cells to maintain energy homeostasis by using existing mitochondria as a template for self-growth and division. As the “energy factory” of organism, disruptions in mitochondrial biogenesis are closely associated with the development of various diseases. Studies have shown that not only the factors involved in mitochondrial biogenesis have circadian oscillations, but also the morphology, dynamics and energy metabolism of mitochondria themselves have cyclic fluctuations throughout the day, suggesting that mitochondrial biogenesis is regulated by the biological clock system, in which the clock gene Rev-erbα plays a key role, it drives mitochondrial biogenesis and synergistically regulates autophagy to normalize a number of physiological processes in the body. Rev-erbα is sensitive to both internal and external environmental changes, and disruptions in circadian rhythms, metabolic diseases, and aging are significant inducers of changes in Rev-erbα expression, and its concomitant inflammation and oxidative stress may be an intrinsic mechanism for inhibiting mitochondrial biogenesis. Therefore, the enhancement of mitochondrial biogenesis by regulating the Rev-erbα activity status may be an important way to improve the pathology and promote the health of organism. Exercise, as a commonly accepted non-pharmacological tool, plays an important role in enhancing mitochondrial biogenesis and promoting health. It has been found that there is a close relationship between exercise and Rev-erbα. On the one hand, exercise stimulation directly affects the expression of Rev-erbα, especially high-intensity and long-term regular exercise; on the other hand, Rev-erbα achieves indirect regulation of exercise capacity by mediating processes such as skeletal muscle mitochondrial biogenesis and autophagy, muscle mass maintenance, energy metabolism and skeletal muscle regeneration. Based on the above findings, it is hypothesized that Rev-erbα may serve as a key bridge between exercise and mitochondrial biogenesis. Exercise enhances the transcriptional response of Rev-erbα in the nucleus, upregulates the expression of Rev-erbα protein in cytoplasm, activates the AMP-activated proteinkinase (AMPK)/ silent information regulator 1 (SIRT1)/peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) pathway, regulates Ca2+ flux and downstream signaling molecules; meanwhile, exercise can upregulate antioxidant gene expression and alleviate oxidative stress through Rev-erbα, which ultimately enhances the function of mitochondria, and promotes mitochondrial biogenesis. In conclusion, the clock gene Rev-erbα emerges as a crucial target for exercise-induced enhancement of mitochondrial biogenesis. In this paper, the biological characteristics ofRev-erbα, the role of Rev-erbα in regulating mitochondrial biogenesis and the factors that may influence it, the interaction between exercise and Rev-erbα, and the potential mechanism of exercise-induced mitochondrial biogenesis via Rev-erbα are sorted out and discussed, which can provide theoretical references to the mechanism of exercise-promoted mitochondrial biogenesis.
ABSTRACT
This article reported a case of a patient with schizophrenia who experienced self-perceived fever and discomfort after taking atypical antipsychotic drugs with strong alpha 1 receptor antagonism, which included olanzapine, risperidone, paliperidone and clozapine. Such phenomenon was believed to be a medication side effect. Therefore, the patient switched to aripiprazole and the fever disappeared. This case report is intended to remind psychiatrists to pay attention to the side effects caused by atypical antipsychotic drugs with strong alpha 1 receptor antagonism as well as to suggest that various factors should be considered, including mechanisms of drug action, patient pathophysiology and individual differences, in order to improve treatment compliance and prognosis.
ABSTRACT
【Objective】 To investigate the safety of regular plasma donors aged 55 to 60, so as to provide reference for retention and recruitment of elderly plasma donors in China. 【Methods】 Plasma donors from 9 blood products manufacturing enterprises from 2018 to 2020 and the local general population were selected as the research objects. The total protein level, albumin and globulin ratio(ALB/GLB, A/G) and adverse reactions of plasma donation of regular plasma donors and local general population were retrospectively analyzed. 【Results】 The total protein level (g/L) and A/G of plasma donors aged 56 to 60 and the general population were 61.21±5.62 vs 60.04±6.93 and 1.610±0.299 vs 1.635±0.330, respectively, and the differences were statistically significant. The total protein level of regular plasma donors was higher than that of general population, but A/G was slightly lower than that of general population. From 2018 to 2020, there were a total of 23 056 302 plasma donations in 108 plasma stations, and adverse reactions occurred in 20 932 donations, with a total incidence of 0.09%, with no serious adverse reactions. 【Conclusion】 It is safe for regular plasma donors aged 55 to 60 to donate plasma, and the retention of them can alleviate the pressure of plasma supply.
ABSTRACT
【Objective】 To explore the characteristics and influencing factors of adverse reactions of apheresis plasma donation in 27 domestic plasma donation stations, and put forward targeted preventive measures. 【Methods】 A total of 6 275 plasma donors with adverse reactions from 2018 to 2020 in 27 plasma donation stations in China were selected as the research objects. The types of adverse reactions, ages, time of plasma donation and other related characteristics were counted and retrospectively analyzed. 【Results】 From January 2018 to December 2020, the incidence of adverse reactions of apheresis plasma donation in 27 plasma collection stations was 1.37‰, including vasovagal reaction/hypovolemia (3 208 cases, 0.700‰), sodium citrate allergy/hypocalcemia (1 205 cases, 0.263‰), hypoglycemia (1 020 cases, 0.223‰), syncope (796 cases, 0.174‰), hematoma (8 cases, 0.002‰), other reactions (36 cases, 0.008‰), all of which were non-severe adverse reactions. There were significant differences in the incidence of different types of adverse reactions (P0.05). 【Conclusion】 The incidence of adverse reactions in plasma donation is low in China. In the process of plasma donation, attention should be paid to first-time and young (18-25 years old) donors. The incidence of adverse reactions in 56-60 years old donors is the lowest, which can provide data support for the age revision of plasma donors in China.
ABSTRACT
Objective@#Diminished ovarian reserve (DOR) is a disorder characterized by impaired ovarian function. Sleep disorders are disruptions of the circadian rhythm, which appears to be closely linked to reproductive systems. This study aimed to investigate the impact of poor sleep quality on the ovarian reserve of childbearing-age women. @*Methods@#A cross-sectional study was conducted in China from June 2021 to March 2023. In total, 102 participants diagnosed with chronic insomnia disorder were included in the study. Questionnaires were administered to assess participants' menstrual patterns, insomnia severity, anxiety, and depression. The anti-Müllerian hormone level and the basal antral follicle count were measured for ovarian reserve evaluation. Correlation analysis and ordinal logistic regression analysis were conducted. @*Results@#The women with insomnia presented high percentages of hypomenorrhea, premenstrual syndrome, and dysmenorrhea (78.4%, 74.5%, and 46.1%, respectively). Severe sleep disorder in the past month was identified as an independent risk factor for hypomenorrhea and premenstrual syndrome (odds ratio [OR], 2.64 and OR, 2.688; p<0.05). The prevalence of DOR among women with insomnia (33.3%) was significantly higher than the average reported in previous studies for young women. Insomnia duration exceeding 1 year was determined to be an independent risk factor for DOR in women aged 36 to 40 years (OR, 4.5; p=0.033). @*Conclusion@#This study highlights the association between sleep disorders and menstrual problems. Prolonged poor sleep quality in women aged 36 to 40 years was identified as a significant risk factor for DOR. We should pay more attention to improving sleep quality in order to maintain normal ovarian function.

ABSTRACT
OBJECTIVE To analyze the prevalence of potentially inappropriate medication (PIM) in elderly patients with femoral neck fractures at admission and compare the concordance of 3 evaluation criteria. METHODS A retrospective study was conducted to review the data of elderly patients with femoral neck fractures admitted to the Department of Orthopedics in Northern Jiangsu People’s Hospital from July 2022 to June 2023. The PIMs were identified according to the Criteria of Potentially Inappropriate Medications for Older Adults in China:2017 edition (hereinafter referred to as Chinese criteria), American Geriatrics Society 2023 Updated AGS Beers Criteria® for Potentially Inappropriate Medication in Older Adults (hereinafter referred to as 2023 Beers criteria), third version criteria for screening tool of older people’s prescriptions for potentially inappropriate medication (hereinafter referred to as STOPP criteria version 3). The concordance of the 3 evaluation criteria was compared by using Kappa statistics. RESULTS A total of 246 patients were included in this study; 49 patients (19.92%) with 77 PIMs were detected by the Chinese criteria, 64 patients (26.02%) with 118 PIMs were detected by the 2023 Beers criteria, and 41 patients (16.67%) with 67 PIMs were detected by the STOPP criteria version 3; 22 patients met all three criteria simultaneously. The concordance among the three criteria showed moderate agreement (0.417≤Kappa≤0.486) when compared in pairs. CONCLUSIONS There are certain differences in the PIM evaluated by the three criteria, but the prevalence of PIMs is below 30% according to the different H202134) criteria. Benzodiazepines, antipsychotics, antidepressants, and other drugs may increase the risk of patients falling again.
ABSTRACT
AIM:To identify transcriptional differences between the ocular surface ectoderm(OSE)and surface ectoderm(SE)using RNA-seq, and elucidate the OSE transcriptome landscape and the regulatory networks involved in its development.METHODS:OSE and SE cells were differentiated from human embryonic stem(hES)cells. Differentially expressed genes(DEGs)between OSE and SE were analyzed using RNA-seq. Based on the DEGs, we performed gene ontology(GO)analysis, Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis, and protein-protein interaction(PPI)network analysis. Transcription factors(TFs)and hub genes were screened. Subsequently, TF-gene and TF-miRNA regulatory networks were constructed using the NetworkAnalyst platform.RESULTS:A total of 4 182 DEGs were detected between OSE and SE cells, with 2 771 up-regulated and 1 411 down-regulated genes in OSE cells. GO-BP analysis revealed that up-regulated genes in OSE were enriched in the regulation of ion transmembrane transport, axon development, and modulation of chemical synaptic transmission. Down-regulated genes were primarily involved in nuclear division, chromosome segregation, and regulation of cell cycle phase transition. KEGG analysis indicated that up-regulated genes in OSE cells were enriched in signaling pathways such as cocaine addiction, axon guidance, and amphetamine addiction, while down-regulated genes were enriched in proteoglycans in cancer, ECM-receptor interaction, protein digestion and absorption, and cytokine-cytokine receptor interaction. Additionally, compared with SE, 204 TFs(including FOS, EGR1, POU5F1, SOX2, and PAX6)were up-regulated, and 80 TFs(including HAND2, HOXB6, HOXB5, HOXA5, and HOXB8)were down-regulated in OSE cells. Furthermore, we identified 6 up-regulated and 9 down-regulated hub genes in OSE cells, and constructed TF-gene and TF-miRNA regulatory networks based on these hub genes.CONCLUSIONS:The transcriptome characteristics of OSE and SE cells were elucidated through RNA-seq analysis. These findings may provide a novel insight for studies on the development and in vitro directed induction of OSE and corneal epithelial cells.
ABSTRACT
Objective To explore the effect of repetitive transcranial direct current stimulation(tDCS)on anti-fatigue capacity,power output,and muscle activation during continuous vertical jumps of aver-age undergraduates.Methods Thirty healthy male college students were randomly assigned to an anodal tDCS(a-tDCS)group and a sham tDCS(sham-tDCS)group,receiving a total of 10 repeated anodal tDCS and sham tDCS for 5 consecutive days on the primary motor cortex respectively.Before and right after the intervention,as well as one month after the intervention,all students underwent the continuous vertical jump test.The two-factor repeated measure ANOVA(stimulation condition×time)was employed to evaluate alterations in fatigue index,total jump height,lower limb stiffness and mus-cle activation characteristics.Results The fatigue index of the a-tDCS group was significantly lower than the sham-tDCS group(P<0.05).After a-tDCS,the total jump height was significantly higher than before(P<0.05).In the sham-tDCS group,the touchdown time during continuous vertical jumps in-creased more significantly right and a month after the intervention(P<0.05 for both).Moreover,lower limb stiffness of the a-tDCS group at the last moment of the continuous vertical jumps was significant-ly higher than the sham-tDCS group(P<0.05).After a-tDCS,the activation of the rectus femoris mus-cle increased significantly in the eccentric phase of the end of the test(P<0.05).However,no signifi-cant differences were found in the mean power and post-test rating of perceived exertion after the stim-ulation.Conclusion Ten sessions of tDCS conducted over five consecutive days demonstrates an en-hancement in neuromuscular activation during high-intensity jumping exercise.This observed augmenta-tion contributes to attenuating the decline in exercise capacity associated with fatigue.
ABSTRACT
Objective:To establish a green fluorescent protein(GFP)and firefly luciferase(Luc)double-labeled Epstein-Barr virus(EBV)infec-ted B lymphoblastoid cell lines(B-LCL)and apply them to mouse models,then compare the advantages and disadvantages of models inocu-lated by intravenous(IV)or subcutaneous(SC).Methods:B lymphoblastoid cell lines double-tagged with GFP/Luc(B-LCL-GL)were con-structed through lentivirus transduction,puromycin intervention.Subcutaneous xenograft and hematogenous metastasis models were re-spectively established by subcutaneous or intravenous injection of B-LCL-GL cells at three concentrations in(NOD)/Prkdcscid/IL-2Rγnull(NPG)mice for in vivo bioluminescence imaging.Results:In the B-LCL-GL group,the ratio of the GFP-positive cell population was 92.5%,and the average luminescence intensity was as high as 4.80E+08 Photons/s,which was considerably higher than that of untreated B-LCLs.In the hematogenous metastasis models,tumor bioluminescence was initially located in the peritoneal area and then spread throughout the en-tire body between 7 and 28 days.In the subcutaneous xenograft models,strong central and weak peripheral tumor-related biolumines-cence signal was detected on day 7 in the three groups,which then spread throughout the body on day 28 in the high-dose group.Taken to-gether,there was no significant difference in tumor progression between the two routes of administration when using the same dose of B-LCL-GL cells.However,the survival analysis indicated that the IV injection group,in which all the mice ultimately died,had a shorter time frame for testing than that of the SC injection group,in which the mice survived until day 100 in the low-dose and medium-dose groups,thus allowing for long-term testing.Conclusions:GFP and Luc dual-positive B-LCLs were successfully established to generate hematogenous metastasis and subcutaneous xenograft models,which allow the monitoring of the location and size of lymphomas in vivo.It provide plat-form for the study of tumor characteristics and selecting anti-tumor drugs.

Health behavior decision-making often involves the balance of gains and losses at different time points,which affects the choice and maintenance of health behaviors.As a cognitive processing method of"pre-experiencing"future events,Episodic Future Thinking(EFT)can promote the formation of health intentions and health behavior change by increasing the value of future health outcomes.This paper reviews the concept,intervention model and action effect of EFT in health behaviors,in order to provide references for nurses to innovate health education and behavior management from the perspective of behavioral economics.
ABSTRACT
Objective:To explore the hotspots and development trend of research in the field of traditional Chinese medicine (TCM) health management in China based on bibliometrics.Methods:With the subject term of “TCM health management” “traditional Chinese medicine”“TCM” “health management”, the relevant literatures on TCM health management were retrieved in databases of CNKI, Wanfang Data, VIP, Web of Science, PubMed, Embase database from the establishment of the databases to December 31st, 2022. After screening and data processing, CiteSpace software was used for visual analysis of the included literature, including network maps of author and institutional collaborations, co-occurrence maps of keywords, burst analysis, timeline cluster maps, and keyword cluster views. This analysis aimed to identify research hotspots and trends in the field of TCM health management in China.Results:A total of 1 294 literatures were eventually included, and since 2013, the number of publications in the field of TCM health management in China had entered a period of rapid growth with the introduction of relevant policies, and it reached a peak in 2019. Li Candong (44 articles) et al. were the core authors in this field, and the research institutions and author groups were mainly concentrated in universities and TCM hospitals. The keywords were mainly “preventive treatment of disease” “TCM physical identification” “community” “hypertension” “elderly” “diabetes”, and the research hotspots were prominent. Among them,“physique”had the longest duration of emergence (2008-2014),“application” had the highest intensity of emergence (10.22), and the emergent words such as “big data” had surged in recent years. The keyword clustering mainly categorized into 3 types: (1) application of TCM health management in terms of hot social needs; (2) research on basic theories of TCM health management; (3) modern technology-enabled TCM health management. The representative keywords of this field in 2016-2022 were“healthcare integration” “application” “artificial intelligence” “Internet+” “intelligent Chinese medicine”and so on.Conclusion:Research in the field of TCM health management in China is heavily influenced by policy factors, resulting in a concentrated effort and uneven development. The research focuses on TCM theory, chronic disease prevention and treatment, combination of medical and nursing care and community application. Intelligent TCM health management modes technologies are emerging as a new research trend.
ABSTRACT
Objective To study the action and mechanism of Sancai Lianmei Particle on cell apoptosis of liver cells in Type 2 Diabetes Mellitus(T2DM)combined with Non-alcoholic Fatty Liver Disease(NAFLD).Methods High fat and sugar + STZ induced diabetic with fatty liver rats used as models,intervention with Sancai Lianmei Particle,intraperitoneal glucose tolerance test(IPGTT)to assess insulin resistance,ELISA method to detect the mice serum biochemistry,insulin levels;ELISA method to detect inflammatory factors in liver homogenate;SOD and MDA levels were monitored to assess the degree of oxidative stress;ASK1/JNK/NF-κB mRNA expression in liver tissue was monitored by Real-time PCR;apoptotic-related proteins were detected by Western blot,apoptosis of hepatocytes was assayed by TUNEL;HE staining was conducted to observe the liver tissue.Results Sancai Lianmei Particle can obviously reduce the body weight of T2DM with NAFLD model rats;reduce the levels of GHb,INS,TC,TG,LDL-C,ALT,AST,IL-1β,IL-6,TNF-α,MDA;improve insulin resistance and oxidative stress.HE staining of liver tissue showed that Sancai Lianmei Particle could alleviate the vacuolar degeneration of liver and deposition of lipid droplets.Sancai Lianmei Particle can effectively down-regulate the expressions of ASK1,JNK and NF-κB mRNA in liver tissues of model rats.Western Blot results exhibited that Sancai Lianmei Particle could significantly regulate the expression of apoptotic proteins of Bax,Caspase-3,and Bcl-2 and inhibit the apoptosis of hepatocytes.Conclusion This study proved that Sancai Lianmei Particle can improve hepatic insulin resistance and oxidative stress,slow the progression of NAFLD by regulating liver cell apoptosis based on ROS-ASK1-JNK/NF-κB pathway.
