Metabolic dysfunction-associated fatty liver disease （MAFLD） is a chronic metabolic liver disorder with complex etiologies. Different clinical phenotypes of MAFLD （such as obesity， hyperlipidemia， type 2 diabetes mellitus， the postmenopausal state， and chronic hepatitis B） have different mechanisms of action in the development and progression of MAFLD， leading to high heterogeneity in its clinical progression and prognosis. This article systematically reviews the pathogeneses and clinical features of the above five clinical phenotypes of MAFLD and elaborates on the corresponding individualized diagnosis and treatment regimens integrating traditional Chinese medicine and Western medicine， in order to provide a reference for clinical practice and improve clinical diagnosis and treatment.

Objective To evaluate the predictive value of neutrophil/high-density lipoprotein cholesterol ratio(NHR)combined with monocyte/lymphocyte ratio(MLR)for early rebleeding after endoscopic treatment in patients with cirrhosis complicated by acute esophagogastric variceal bleeding(AEVB).Methods A total of 228 patients with cirrhosis complicated by AEVB were included in this study.According to the occurrence of early rebleeding,patients were divided into the rebleeding group(96 cases)and the non-rebleeding group(132 cases).General information and laboratory indicators of both groups were collected,and the End-Stage Liver Disease(MELD)score,Child-Turcotte-Pugh(CTP)score,Fibrosis-4(FIB-4)index,NHR,and MLR were calculated.Logistic regression analysis was used to identify the risk factors for early rebleeding in patients with cirrhosis complicated by AEVB.A nomogram model based on NHR and MLR was constructed to predict the risk of early rebleeding.The predictive performance and goodness of fit of the model were evaluated using receiver operating characteristic(ROC)curve,Hosmer-Lemeshow test,Net Reclassification Index(NRI)and Integrated Discrimination Improvement(IDI).Results Compared with the non-rebleeding group,systolic blood pressure,platelet count(PLT),albumin/globulin ratio(A/G)and low-density lipoprotein cholesterol(LDL-C)were decreased in the rebleeding group,while total bile acids(TBA),aspartate aminotransferase(AST),alanine aminotransferase(ALT),total bilirubin(TBIL),activated partial thromboplastin time(APTT),thrombin time(TT),international normalized ratio(INR),Fibrosis-4(FIB-4),NHR,MLR,MELD score and CTP score were increased(P＜0.05).NHR was positively correlated with AST,TBIL and INR(P＜0.05).MLR was negatively correlated with PLT,and positively correlated with AST,TBIL and FIB-4(P＜0.05).Logistic regression analysis results showed that prolonged TT,elevated NHR and MLR were independent risk factors for early rebleeding in patients with cirrhosis complicated by AEVB.The nomogram model based on NHR and MLR to predict early rebleeding had an area under the curve of 0.810(95%CI:0.754-0.866).The Hosmer-Lemeshow test suggested that the model fit well.IDI and NRI analyse showed that the combination of NHR and MLR had better predictive value for the early rebleeding than that of MELD score and CTP score.Conclusion NHR and MLR are effective indicators for predicting early rebleeding after endoscopic treatment in patients with cirrhosis complicated by AEVB.They are helpful in the early identification of high-risk patients and provide a reference for clinical intervention.

Under the influence of long-term space flights and the confined space environment,it is very easy to induce space depression syndrome,mainly manifested as decreased emotional stability,sleep disorders,mental fatigue,etc.,which seriously affect the living conditions and working abilities of astronauts.The current treatment methods mainly focus on psychological support and drug intervention.Acupuncture has a good effect in treating depression.Therefore,starting from the TCM pathogenesis and modern medical pathogenesis of aerospace depression syndrome,we conducted literature retrieval from databases such as the Chinese Medical Classic,China National Knowledge Infrastructure(CNKI),Wanfang,VIP,PubMed,and Web of science.For the included literature,we adopted the stratified evidence scoring method and combined the TCM mechanism and modern medical mechanism of the effect of acupuncture.A prescription for acupuncture points was constructed to provide a basis for selecting acupuncture points for the prevention of aerospace depression syndrome through acupuncture.

Objective:To explore the effect of scalp electroacupuncture (EA) on central pain sensitization in rats with knee osteoarthritis (KOA).Methods:Thirty-two 8-week-old female Sprague-Dawley rats were randomly divided into a blank control group, a model group, an electroacupuncture (EA) group and a sham EA group, each of 8. All of the rats except those in the control group had KOA induced through intra-articular monosodium iodoacetate injections in the right knee. Two weeks later the EA group rats began receiving daily head EA sessions 6 days/week for 2 weeks. The sham EA group received identical but non-therapeutic stimulation. The blank control and model groups received no EA intervention. Before the modelling and 3, 7, 14, 21 and 28 days later, all of the rats completed bipedal balance pain tests and mechanical allodynia evaluations. After the testing on day 28, all of the rats were euthanized for molecular analyses. Western blotting and immunohistochemistry were performed to examine protein expression of brain-derived neurotrophic factor (BDNF), tropomyosin receptor kinase B (TrkB), and cannabinoid receptor type 1 (CB1R) in both the periaqueductal gray (PAG) matter and spinal dorsal horns (SDHs). Serum levels of substance P (SP) and 5-hydroxytryptamine (5-HT) were also quantified using enzyme-linked immunosorbent assays.Results:Three days after successful modeling, the average weight-bearing capacity of the right hind limb in the model, sham EA and EA groups was significantly lower than that of the blank controls. It reached its lowest level on the 14th day after modeling. Concurrently, the pain responses in those three groups were significantly higher than among the controls, also peaking on the 14th day after modeling. After two weeks of electroacupuncture, the electroacupuncture group showed significant improvement in both right hind limb weight-bearing capacity and pain response compared to the model group. Meanwhile, the levels of BDNF and TrkB protein in the periaqueductal gray matter were significantly higher in the model group than among the blank controls, while the electroacupuncture group exhibited significantly reduced expression of BDNF and TrkB proteins compared to the model group, along with significantly increased CB1R protein expression. The model group showed significantly elevated expression of both BDNF and TrkB proteins in the spinal dorsal horn compared to the blank control group, while there were significant differences between the EA and model groups in the expression of BDNF, TrkB and CB1R proteins. Immunohistochemical analysis on day 28 revealed that the EA group had significantly fewer BDNF- and TrkB-positive cells in the PAG compared to the model group, with significantly more CB1R-positive cells. In the SDH, the model group exhibited significantly increased numbers of BDNF- and TrkB-positive cells compared to the blank control group, whereas significant differences were found between the EA and blank control groups in the numbers of BDNF-, TrkB- and CB1R-positive cells. Serum analysis on day 28 demonstrated that substance P and 5-hydroxytryptamine levels in the model, sham EA and EA groups were significantly higher than in the blank control group, on average. However, no significant differences were observed in serum SP and 5-HT levels between the EA and model groups.Conclusions:Scalp EA significantly alleviates central pain sensitization in KOA, at least in rats, potentially by suppressing BDNF and TrkB expression while upregulating CB1R expression in the PAG matter and the SDH.

Objective:To explore the correlation between serum 1, 5-anhydroglucitol (1, 5-AG) and mild cognitive impairment (MCI) in elderly patients with type 2 diabetes mellitus (T2DM).Methods:A total of 160 patients with T2DM aged 60-75 years old who visited the First Hospital of Hebei Medical University from May 2021 to July 2022 were selected. According to the Montreal cognitive assessment (MoCA), all patients were divided into T2DM with MCI group (T2DM+ MCI group, n=81) and T2DM without MCI group (T2DM group, n=79). All research subjects were tested for glycated hemoglobin A1c (HbA1c), serum 1, 5-AG, serum β-amyloid peptide 42 (Aβ42), and blood biochemical indicators.SPSS 25.0 statistical software was used for data analysis. The t test, Mann-Whitney U test and χ2 test were used to compare the two groups. Binary Logistic regression analysis was used to examine the relevant influencing factors. Results:(1) Compared with T2DM group, patients in T2DM+ MCI group had significantly higher age, systolic pressure and HbA1c(all P<0.05).The level of 1, 5-AG in T2DM+ MCI group was significantly lower than that in T2DM group( (15.65±2.56 )μg/mL, (18.17±3.72 )μg/mL, P<0.01), and the level of Aβ42 was higher than that of T2DM group (2.95 (3.36) pg/mL, 1.91 (2.48) pg/mL, P<0.05). (2) Binary Logistic regression analysis results showed that HbA1c( β=0.230, OR=1.259, 95% CI=1.010-1.568, P=0.040) and Aβ42( β=0.188, OR=1.206, 95% CI=1.033-1.409, P=0.018) were the independent risk factors for MCI in elderly patients with T2DM, while 1, 5-AG ( β=-0.240, OR=0.786, 95% CI=0.698-0.886, P<0.001) was the protective factor for MCI. Conclusion:There is a positive correlation between serum 1, 5-AG and cognitive function, and the decrease of 1, 5-AG level was associated with the increased risk of MCI in elderly patients with T2DM.

Objective To evaluate the effect of standardized lipid-lowering therapy in acute stroke patients via high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)to follow-up the characteristics changes of intracranial atherosclerotic plaques.Methods Twenty-two acute stroke patients(65 plaques)were enrolled,and their clinical and imaging data were collected on admission and after standardized lipid-lowering therapy(355-370 days).Diffusion weighted imaging(DWI),three-dimensional time of flight magnetic resonance angiography(3D-TOF-MRA),and HRMR-VWI were performed in all patients.According to the changes in non-high density lipoprotein(non-HDL),all patients were divided into the effective lipid-lowering group and the ineffective lipid-lowering group.The demographic information,plaques characteristics and the effect of standardized lipid-lowering therapy of all patients were compared.Results One(2.33％)plaque in the effective group showed reverse remodeling and four(18.18％)new plaques in the anterior circulation in the ineffective group.Patients in the effective group were significantly better than those in the ineffective group in terms of plaque thickness,load,remodeling index(RI),and the rate of increase in plaque thickness,load,stenosis,and RI,with statistically significant difference(P＜0.05).There was no statistical significance in the rate of stenosis between the two groups.Conclusion Standardized lipid-lowering therapy has differences in the prognosis of acute stroke patients,and HRMR-VWI may be conducive to individualized assessment of the lipid-lowering effect.
