MethodsA randomized ， double-blind， positive-controlled，multi-center clinical trial was conducted， in which 370 patients with SAP of qi stagnation and blood stasis syndrome were randomly divided into treatment group（279 cases）and control group（91cases）at a ratio of 3∶1. The treatment group was orally administered with YDMHP， 3 g each time， and placebo of Xuefu Zhuyu Capsule （血府逐瘀胶囊）， 2.4 g each time， while the control group was treated with Xuefu Zhuyu Capsule， 2.4 g each time， and placebo of YDMHP， 3 g each time， both twice a day for a course of 12 weeks. The primary outcome was the effect of angina pectoris symptom. The secondary outcomes include single angina symptom scores such as number of attacks， duration of attacks， pain intensity and usae of nitroglycerin scores， the total angina symptom score before and after the treatment， the usage of nitroglycerin， the exercise duration in treadmill exercise test （TET） and the Duck treadmill score among patients，the scores of Seattle Angina Questionnaire （SAQ） on five dimensions including physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception， and efficacy of TCM syndrome and of each single TCM symptom after treatment. The safety were evaluated by examine blood routine， urine routine， liver and kidney function， fasting blood sugar， electrocardiogram， adverse events. ResultsThe total effective rate of angina symptom in the treatment group was 71.69% （200/279）， significantly higher than 51.64% （47/91） in the control group （P＜0.01）. The curative and markedly effective rate of TCM syndrome in the treatment group was 53.05% （148/279）， which was significantly higher than 25.27% （23/91） in the control group （P＜0.01）. After treatment， scores of the number as well as duration of angina attacks and pain severity， the total score of angina symptoms， and the usage of nitroglycerin significantly decreased in both groups， and more changes were seen in the treatment group than in the control group； the scores of physical limitations， anginal stability， anginal frequency， treatment satisfaction， and disease perception in both groups significantly increased， and more improvement were shown in the experimental group regarding the anginal stability， anginal frequency and treatment satisfaction （P＜0.05 or P＜0.01）. The effects of chest pain， chest tightness， palpitation， shortness of breath and fatigue in experimental group were significantly higher than those in control group （P＜0.05 or P＜0.01）. There was no significant difference in the exercise duration of treadmill test and Duke score among patients between the two groups either before or after treatment （P＞0.05）. Adverse events occurred in 66 cases （23.66%） of the experimental group and 16 cases （17.58%） of the control group， with no statistical significance between the two groups （P＞0.05）. ConclusionThe Uyghur medicine YDMHP can effectively improve symptoms of angina pectoris， reduce the number， duration， and intensity of attacks， decrease the dosage of nitrogly-cerin and improve the individual TCM symptoms and has good safety in the treatment of SAP patients of qi stagnation and blood stasis.

Tooth absorption can be divided into physiological absorption and pathological absorption.Root absorp-tion of mature deciduous teeth is physiological absorption.Pathological absorption includes internal absorption and ex-ternal absorption.Internal absorption,also known as intramedullary absorption,includes inflammatory absorption and al-ternative absorption.External tooth absorption originates from the outer surface of the root or the neck of the tooth and can be divided into inflammatory absorption,alternative absorption,pressure resorption and invasive cervical resorption.Invasive cervical resorption(ICR)is pathological damage caused by many factors,which usually begins in the cemento-enamel junction and extends peripherally or horizontally in the dentin.It hardly invades the pulp.Orthodontic devices,trauma,bleaching,systemic diseases,and the use of certain medications can all lead to invasive cervical resorption.The clinical manifestations of ICR are usually asymptomatic or not obvious,and most of which are found in imaging examina-tions.Because caries and internal absorption are often misdiagnosed through plain apical radiography,cone beam com-puted tomography(CBCT)can help to better understand the situation of invasive cervical resorption.Because the patho-genesis and etiology of invasive cervical resorption are not fully understood,clinical negligence and inadequate treat-ment of invasive cervical resorption can even cause unnecessary tooth loss.This article reviews the latest research prog-ress on the histopathologic features,pathogenic mechanism,susceptibility factors,diagnosis and treatment of ICR,with special emphasis on susceptibility factors and their mechanisms.

Aim To explore the correlation between carotid atherosclerosis(CAS)and neutrophil/lymphocyte ratio(NLR)in patients with early morning hypertension,and to construct a line chart model to predict the risk of CAS in patients with hypertension in the morning.Methods 255 patients with early morning hypertension hospitalized in the Affiliated Hospital of Chengde Medical College from October 2019 to November 2022 were collected,and their basic data,blood routine and blood biochemical indexes were collected.All selected patients need to improve 24-hour ambulatory blood pressure monitoring and carotid artery color ultrasound detection.According to the presence or absence of CAS,all selected patients were divided into morning hypertension with CAS group(n=197)and morning hypertension without CAS group(n=58).Multivariate Logistic regression analysis was used to explore the risk factors of early morning hypertension with CAS,and to construct and verify an individual line chart model to predict the risk of early morning hypertension pa-tients with CAS.Results The age,NLR,neutrophils(NE),monocytes(MO),white blood cell(WBC),total cho-lesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDLC)increased in the early morning hyperten-sion with CAS group compared with those in the morning hypertension group without CAS,while the HDLC decreased(P＜0.05).The results of multivariate Logistic regression analysis showed that the age,NLR and TC were higher in the early morning hypertension with CAS group than those in the early morning hypertension without CAS group,while HDLC was lower;Age,NLR and TC were independent risk factors of early morning hypertension with CAS,while HDLC was inde-pendent protective factors of morning hypertension with CAS.Based on the results of multivariate Logistic regression anal-ysis,an individualized line chart model for predicting early morning hypertension with CAS was constructed.The area un-der the ROC curve of the line chart model was 0.853(95％CI:0.802-0.904,P＜0.01).The result of Hosmer Leme-show fit test was x2=1.665(P＞0.05).Conclusions There was a positive correlation between NLR and morning hy-pertension with CAS,and NLR was an independent risk factor for morning hypertension with CAS.The individualized line chart model based on age,NLR,TC and HDLC can effectively predict the risk of hypertension with CAS in the early morn-ing,which provides a theoretical basis for early detection and prevention of atherosclerosis.

OBJECTIVE: To observe the therapeutic effect of electroacupuncture at acupoints of liver meridian in patients with diminished ovarian reserve (DOR) of liver depression. METHODS: A total of 62 patients with DOR of liver depression were randomly divided into an electroacupuncture group (31 cases, 1 case discontinued) and a western medication group (31 cases, 1 case was eliminated). Electroacupuncture was applied at bilateral Taichong (LR 3), Ligou (LR 5), Ququan (LR 8), Jimai (LR 12) in the electroacupuncture group, with continuous wave, in frequency of 2 Hz and current of 0.5-1.0 mA, 30 min each time, once every other day, 3 times a week. Femoston was taken orally in the western medication group, oral estradiol tablets were taken for the first 14 days, followed by oral estradiol/progesterone complex tablets for the rest 14 days, 1 tablet a day. Both groups were treated for 3 consecutive menstrual cycles. Before and after treatment, the scores of TCM syndrome, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were observed, serum levels of follicle stimulating hormone (FSH) and anti-Müllerian hormone (AMH) were detected, and antral follicle count (AFC), peak systolic velocity (PSV) and resistance index (RI) of ovarian artery were measured by color Doppler ultrasound in the two groups, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the scores of primary symptom and secondary symptom, as well as the total scores of TCM syndrome were decreased compared with those before treatment (P<0.01), the scores of SAS and SDS, as well as the serum FSH levels and RI of ovarian artery were decreased compared with those before treatment (P<0.01), while the serum AMH levels, AFC and PSV of ovarian artery were increased compared with those before treatment (P<0.05, P<0.01) in the two groups. After treatment, in the electroacupuncture group, the primary symptom score of TCM syndrome was higher than that in the western medication group (P<0.01), the secondary symptom score of TCM syndrome and the scores of SAS and SDS were lower than those in the western medication group (P<0.05, P<0.01). The total effective rate was 70.0% (21/30) in the electroacupuncture group and 73.3% (22/30) in the western medication group respectively, there was no significant difference in the total effective rate between the two groups (P>0.05). CONCLUSION Electroacupuncture at acupoints of liver meridian can effectively improve the clinical symptoms, anxiety and depression, regulate the serum sex hormone levels, increase AFC and improve ovarian blood supply in DOR patients of liver depression.

Objective:To investigate the effect of melatonin (MEL) influence on lipopolysaccharide (LPS)-induced long-term anxiety-like behavior and activation of astrocytes in septic neonatal rats.Methods:Sprague-Dawley rats were randomly(random number) assigned to the control group, LPS group and LPS+MEL group. Sepsis model was intraperitoneally injected with LPS (1 mg/kg), and neonatal rats in the MEL group were administered with MEL (10 mg/kg) 30 min after LPS injection. At different time points after injection, rats in each group were divided into three subgroups: 3 d, 7 d and 28 d. The expression of GFAP and TNF-α in the corpus callosum was detected by immunofluorescence staining and Western blot. Open-field test was applied to observe anxiety-like behaviors. In vitro, cultured neonatal SD rat astrocytes were divided into the control group, LPS group, LPS+MEL group, and LPS+MEL+luzindole group. Immunofluorescence staining was used to observe the expression of GFAP and TNF-α. Expression of GFAP, TNF-α, p-NF-κBp65, NF-κBp65 protein in astrocytes were assessed by Western blot. RT-qPCR was used to investigate the mRNA expression of GDNF and BDNF. One-way ANOVA and two-way ANOVA were used for comparison of multiple groups of variables. A P<0.05 was considered statistically significant. Results:LPS reduced the duration of movement in the central area and distance in the central area/total distance in open-field test, while melatonin evidently reversed the LPS-induced anxiety-like behavior. Compared with the LPS group, the expressions of GFAP and TNF-α were significantly decreased in the corpus callosum at 3 d and 7 d in the MEL group ( P< 0.05). Compared with the LPS group, MEL could significantly decrease the expression of GFAP, TNF-α and p-NF-κBp65 in astrocytes ( P< 0.05), which could be blocked by Luzindole. In addition, compared with the LPS group, MEL pretreatment could reverse the down regulation of GDNF and BDNF induced by LPS ( P<0.05). Conclusions:MEL can relieve LPS-induced long-term anxiety-like behavior in septic neonatal rats. The mechanism may be related to the inhibition of astrocyte activation and inflammatory reaction through NF - κ B pathway.

Objective:To investigate the cause of missed diagnosis by transthoracic echocardiography (TTE) based on the characteristics of partial anomalous pulmonary venous connection (PAPVC), and to improve the ultrasonic diagnostic accuracy of PAPVC in children.Methods:The TTE results of 252 children under 12 years old who were confirmed with PAPVC at Guangdong Provincial People′s Hospital from January 2011 to June 2019 were reviewed retrospectively.The types of PAPVC and the associated atrial septal defects (ASD) as well as the confirmed and missed cases by TTE were analyzed.Results:PAPVC was right-sided in 238 patients (94.4%), left-sided in 8 patients (3.2%), and bilateral in 6 patients (2.4%). There were 177 cases (70.2%) whose pulmonary veins were abnorma-lly connected to the right atrium(RA), 37 cases (14.7%) to the junction of the RA and the superior vena cava (SVC), 27 cases (10.7%) to the distal SVC, and 6 cases (2.4%) to the inferior vena cava.Besides, pulmonary veins of 5 cases (2.0%) flew back to the RA through the coronary sinus.One hundred and ninety PAPVC cases were combined with sinus venous defects (SVD) and 53 cases combined with secondum ASD.Two hundred and twenty-one cases were accurately diagnosed while 31 cases were underestimated by TTE.The omission diagnostic rates of right superior pulmonary veins connecting to the distal SVC, 1 or 2 right pulmonary veins connecting to the RA or the junction of the RA and SVC, and left-sided PAPVC were 8 out of 18 (44.4%), 22 out of 215 (10.2%) and 1 out of 8 (12.5%), respectively.Among 54 cases with right superior pulmonary veins anomalously connected to the RA or the junction of the RA and SVC, 88.9% of them (48/54 cases) were combined with superior SVD.Among 161 cases with the right inferior pulmonary veins or 2 right pulmonary veins connected to the RA, 78.2% of them (126/161 cases) were combined with inferior SVD.There were statistically significant differences in ASD types between the 2 right-sided PAPVC groups.Conclusions:SVD is often associated with 1 or 2 right pulmonary veins connected to the RA or the junction of the RA and SVC.The cases with right superior pulmonary veins connected to the distal SVC are prone to be underestimated by TTE.Whether there is abnormal blood flowing into SVC should be noticed during superior sternal fossa examinations.Each pulmonary vein should be examined in detail in the TTE test and accurate diagnosis of PAPVC can be made in most cases.

Objective:To investigate the effect of melatonin on oligodendrocyte maturation and differentiation in corpus callosum of septic neonatal rats induced by systemic lipopolysaccharide (LPS) injection.Methods:Sprague-Dawley rats were randomly allocated into the control group, septic experimental group, and melatonin group. In the septic experimental group, rats were intraperitoneally administrated with lipopolysaccharide (LPS) (1 mg/kg). In the melatonin group, melatonin was intraperitoneally administered (10 mg/kg) at 0.5 h after LPS injection. The expression level of IL-6, olig1, olig2, and the MAG protein were detected by Western blot at different time points in the three groups. BV-2 cells were used in vitro. For drug administration, the effect of LPS, melatonin and melatonin receptor antagonist, luzindole, on IL-6 expression in BV-2 microglia cell was determined by Western blot. The medium of BV2 cell were collected to treat primary OPCs. The expression level of olig1, olig2 and MAG protein in primary OPCs were detected by Western blot. SPSS 20.0 statistical software was used for analysis, and the data were analyzed by one-way ANOVA and two-way ANOVA. Differences were considered to be statistically significantly if P<0.05. Result:Compared with the LPS group, the expression of IL-6 was significantly decreased in the corpus callosum at 6 h, l d, and 3 d in the melatonin group ( P<0.05). The expression of olig1, olig2 and MAG protein were increased at day 7, 14, and 28 in the melatonin group compared with the LPS group ( P<0.05). In vitro the expressions of IL-6 was significantly increased after LPS treatment ( P<0.05), but was decreased in the LPS+melatonin treatment group ( P<0.05). After treatment with melatonin receptor inhibitor, luzindole, the expressions level of IL-6 was increased ( P<0.05). The expression of olig1, olig2 and MAG protein were decreased with conditioned medium in the LPS BV2 cell group than the control group in the primary OPCs ( P<0.05). However, those were increased with conditioned medium in the LPS+melatonin BV2 cell group than the LPS group ( P<0.05). Conclusions:Melatonin may inhibit the inflammation response in the corpus callosum through its receptor, and may promote the maturation and differentiation of oligodendrocyte, suggesting that melatonin may have therapeutic effect on neuroinflammation and axonal hypomyelination on PWM in septic neonatal rats.

Objective:This study analyzes the expression level of miR-1180-3p and constructs the regulatory network of relevant ceRNA by integrating the DNA methylation and gene expression profile of hepatocellular carcinoma from the Cancer Genome Atlas (TCGA).Methods:Firstly, the expression level of miR-1180-3p in hepatocellular carcinoma and adjacent tissues was analyzed by TCGA database, and the differential expression of lncrna and mRNA was screened. Secondly, the LncBase database and the TargetScan database were used to predict the relationship between miR-1180-3p and lncRNA and mRNA, and the DNA methylation-mediated lncRNA was screened by the DNA methylation profile of lncRNA. Finally, Cytoscape software was used to construct miR-1180-3p relevant ceRNA network, and WebGestalt website was used to perform GO and KEGG analysis of related mRNA in ceRNA.Results:Compared with patients with low expression of miR-1180-3p (mean overall survival duration, 5.69 ± 0.35 years), patients with high expression of miR-1180-3p had shorter overall survival time (mean overall survival duration, 3.99 ± 0.47 years), indicating that the high expression of miR-1180-3p was hepatocellular carcinoma risk factor affecting the prognosis ( HR = 1.28, 95% CI = 1.1 ~ 1.5, P < 0.01). A miR-1180-3p related ceRNA regulatory network was constructed in this study, which contained 2 lncRNAs (F11-AS1 and LINC01511) and 37 mRNAs. Conclusion:This study has successfully constructed miR-1180-3p relevant ceRNA regulatory network, and DNA methylation-mediated F11-AS1 and F11-AS1/miR-1180-3p/C11of54 ceRNA regulatory axis has played an important role in the occurrence and development of hepatocellular carcinoma.

Objective:To screen and analyze the differentially-expressed genes (DEGs) in primary hepatocellular carcinoma tissues and adjacent tissues using bioinformatics methods to explore the molecular mechanism of the occurrence and prognosis of primary hepatocellular carcinoma.Methods:GSE76427 data set was collected through GEO database, and DEGs were identified using GEO2R online analysis. Go and KEGG databases were used for enrichment and functional annotation of DEGs. Protein interaction network was built based on the STRING database and Cytoscape software to analyze the key genes of hepatocellular carcinoma, and the survival curve of these key genes were analyzed using the GEPIA database.Results:A total of 74 hepatocellular carcinoma DEGs were screened, of which 3 and 71 were up-and-down-regulated genes. The results of GO enrichment analysis showed that the down-regulated DEGs were mainly involved in cell response to cadmium and zinc ions, negative growth regulation, heterologous metabolic processes and hormone-mediated signaling pathways. KEGG pathway enrichment analysis results showed that the down-regulated DEGs pathway were mainly involved in retinol metabolism, chemical carcinogenesis, drug metabolism-cytochrome P450, cytochrome P450 metabolizing xenobiotics, tryptophan metabolism and caffeine metabolism. Protein interaction network had screened out 10 down-regulated core genes: MT1G, MT1F, MT1X, MT1E, MT1H, insulin-like growth factor 1, FOS, CXCL12, EGR1, and BGN. Among them, the insulin-like growth factor 1 was related to the prognosis of primary hepatocellular carcinoma.Conclusion:Bioinformatics analysis results of HCC chip data showed that 10 key genes may play a key role in the occurrence and development of HCC and the insulin like growth factor 1 is associated with the prognosis of primary hepatocellular carcinoma.

Objective To investigate the effect of interleukin-1β (IL-1β) on the expression of synaptic protein SNAP-25 in the hippocampus in septic neonatal rat induced by systemic lipopolysaceharide (LPS) injection.Methods Sprague-Dawley (SD) rats were randomly divided into two groups:control group and sepsis group.The rat model of sepsis was produced by intraperitoneal injection of 1 mg/kg LPS,and rats in the control group were injected with an equal volume of 0.01 mol/L phosphate buffered saline (PBS).The expression levels of IL-1β and IL-1R1 in the hippocampus at 1,2 and 3 d,and synaptosomal-associated protein 25 (SNAP-25) at 7,14 and 24 d after LPS intraperitoneal injection were detected by Western blot.After cultured for 24 h,primary hippocampal neurons were divided into four groups including the control group,IL-1β (40 ng/mL) treatment group,IL-1β (40 ng/mL) + IL-1Ra (40 ng/mL) treatment group,and IL-1Ra (40 ng/mL) treatment group.The effect of IL-1β on SNAP-25 expression in primary hippocampal neuron was determined by Western blot and real-time PCR.The purity of hippocampal neurons were identified by NeuN immunofluorescence staining and the activity of neurons were detected by CCK-8 assay.All data were analyzed by SPSS version 22.0.The data were analyzed by student-t test and Dunnett-t test.The interaction effects were analyzed by factorial ANOVA.Differences were considered to be statistically significant if P＜ 0.05.Results Compared with the control group,the expressions of IL-1β and IL-1R1 were significantly increased in the hippocampus at 1,2 and 3 d after intraperitoneal injection of LPS (P＜0.05).The expression of SNAP-25 protein was decreased at 7,14,and 28 d after intraperitoneal injection of LPS (P＜0.05).The purity of primary neurons was about up to 92％.The activity of primary neurons was not relatively changed after treated with IL-1β at a dose less than 40 ng/mL.The level of SNAP-25 protein was obviously decreased in primary neurons at 24 h after IL-1β treatment (P＜0.05).IL-1Ra treatment might reverse the effect of IL-1β on primary neurons (P＜0.05).While,the expression of SNAP-25 mRNA was not statistically different in each group (P＞0.05).Conclusions IL-1β may possibly inhibit the expression level of SNAP-25 protein in the hippocampus in the septic rats through its receptor IL-1R1,which would contribute to cognitive dysfunction of septic neonatal rats in later life.
