ABSTRACT

Osteoarthritis (OA), rheumatoid arthritis (RA), gouty arthritis (GA), and intervertebral disc degeneration (IVDD) are the most common bone and joint-related diseases in clinical practice. They can all affect related joints, leading to joint pain, swelling, dysfunction, and other symptoms. The difference is that OA is mainly caused by joint wear and age-related degradation and is manifested as joint pain, stiffness, and limited movement. RA is an autoimmune disease, manifested as joint pain, swelling, morning stiffness, and systemic symptoms. GA is caused by abnormal uric acid metabolism, manifested as acute arthritis, and IVDD is caused by intervertebral disc degeneration. Studies have shown that the mechanism of the occurrence and development of these bone and joint diseases is extremely complex. Pyroptosis is closely related to these bone and joint-related diseases by participating in bone and joint inflammation, cartilage metabolism imbalance, extracellular matrix degradation, and pathological damage of bone and joint. Inhibition of bone and joint-related pyroptosis will effectively prevent and treat bone and joint-related diseases. At the same time, many studies have confirmed that traditional Chinese medicine (TCM) has a prominent curative effect and obvious advantages in the prevention and treatment of bone and joint-related diseases. TCM can reduce the inflammatory reaction of bone and joints, improve the pathological damage of bone and joint diseases, and relieve bone and joint pain by inhibiting pyroptosis. Therefore, this article aims to briefly explain the relationship between pyroptosis and the occurrence and development of bone and joint-related diseases and summarize the latest research reports on the intervention of pyroptosis in the treatment of bone and joint-related diseases by TCM monomers, TCM extracts, and TCM compounds. It offers new ideas for the in-depth study of the pathogenesis and drug treatment of bone and joint diseases and provides a basis for the clinical use of TCM to prevent and treat bone and joint diseases.

ABSTRACT

Osteoarthritis (OA) is a common chronic, highly prevalent, painful, and disabling degenerative joint disease. It has imposed a heavy burden on social healthcare and patients' psychology and economy due to its clinical symptoms such as impaired joint mobility and severe joint pain and the immature therapies. Studies have shown that OA is closely associated with articular cartilage dysfunction, synthesis and degradation disorders of chondrocyte extracellular matrix (ECM), and joint inflammation. Moderate autophagy can restore the function of damaged chondrocytes, regulate chondrocyte apoptosis, and promote the synthesis and metabolism of ECM to alleviate the inflammation of joints and delay the onset and progression of OA. According to the clinical symptoms, OA can be classified into the category of impediment in traditional Chinese medicine. With the theories of holistic conception, treatment based on syndrome differentiation, and individualised diagnosis and treatment, traditional Chinese medicine has demonstrated definite effects in the treatment of OA in thousands of years of practice. Moreover, traditional Chinese medicine causes mild adverse reactions, and the patients have high tolerance and acceptance. This paper briefly explains the roles of autophagy and the related regulatory proteins, such as Unc-51-like autophagy-activated kinase 1 (ULK1), Beclin-1, and microtubule-associated protein light chain 3 (LC3), and details the latest research achievements in the prevention and control of OA by traditional Chinese medicines and its related markers via the regulation of autophagy, so as to provide a idea for the in-depth research in this field and the clinical application of traditional Chinese medicine in preventing and treating OA.

ABSTRACT

Objective:To investigate the effectiveness of nasal endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum in resecting recurrent nasal inverted papilloma. Methods:Patients with recurrent nasal inverted papilloma who underwent reoperation in our hospital during the past 2 years were included . The nasal septum may hinder full access to and effective treatment of the lesions at the anterior and medial wall of the maxillary sinus by endoscope, aspirator and surgical instrument in the narrow aperture of the prelacrimal recess, although these lesions could be observed by 70° nasal endoscope. Results:The nasal septum is temporarily opened on the basis of the prelacrimal recess approach, and the nasal endoscope and instrument was introduced through trans-septal window, so as to provide a better view of the operative field and the angular range of the instrument's movement. Conclusion:The recurrent nasal inverted papilloma could be successfully managed by re-endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum, and no recurrence was observed during the 2-year follow-up. This surgical approach is recommended for the inverted papilla which originates from the anterior medial wall of the maxillary sinus, as the tumor can be removed completely using this surgical approach.

ABSTRACT

Objective:To analyze the clinical and laboratory characteristics of acute myeloid leukemia (AML) patients with NPM1 mutation, and to explore the prognostic factors.Methods:A total of 77 AML patients with NPM1 gene mutation admitted to Hebei Yanda Ludaopei Hospital from May 1st 2012 to December 31st 2021 were enrolled in the study, including 34 male and 43 female patients. The median age was 40 (3, 68) years old. Patients were selected and divided into 4 groups according to the morphological FAB classification. There were 29 cases (37.7%) of M1 type, 13 cases (16.9%) of M2 type, 23 cases (29.9%) of M4 type, and 12 cases (15.5%) of M5 type. The clinical characteristics, bone marrow/peripheral blood cell morphology, immunophenotype, cytogenetics, molecular biology and overall survival of different groups were retrospectively analyzed, and the risk factors affecting the prognosis of AML were also explored. Cox multivariate regression was used to analyze the clinical influencing factors of survival and prognosis.Results:The white blood cell counts were highest in M4 and M5 patients and lowest in M2 patients, while no significant difference in the red blood cell, hemoglobin, and platelet counts( P>0.05). Morphologically, there were significant differences in the percentage of blasts and blasts with cup-like nuclei on bone marrow (BM) and peripheral blood (PB). The proportion of blasts in BM and PB was the highest in M1 and the lowest in M2 ( P<0.001). The positive rate of blasts with cup-like nuclei was the highest in M1 and the lowest in M5 of BM ( P<0.001), while the highest in M2 and the lowest in M5 of PB ( P=0.006). The scores of myeloperoxidase and chloroacetate esterase were all the highest in M1 and the lowest in M5 ( P<0.001, 0.001, respectively). In terms of molecular biology, the occurence rate of blasts combined with DNMT3A mutation was the highest in M4 and the lowest in M2 ( P=0.044), while those combined with FLT3-ITD mutation was the highest in M4 and the lowest in M5 ( P=0.002). In immunophenotype, there were significant differences in the expression positivities of seven antigens including HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO ( P<0.05). Multivariate COX regression analysis showed that no recurrence after treatment ( P<0.001), complete remission after treatment ( P=0.015) and transplantation ( P<0.001) were correlated with overall survival (OS). No recurrence after treatment ( P=0.033), transplantation ( P=0.027), no mutation of FLT3-ITD ( P=0.040), and hemoglobin concentration ( P=0.023) were associated with relapse-free survival (RFS). Survival analysis by Kaplan-Meier curve showed that there was no significant difference in survival time between the M1, M2, M4 and M5 groups in OS and RFS. Conclusion:There were significant differences in the white blood count, the percentage of blasts and blasts with cup-like nuclear morphology, cytochemical staining (MPO integration, CE integration and percentage of NAS-DCE), gene mutation (DNMT3A and FLT3-ITD) and immunophenotypes (HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO) between the four groups. The multivariate analysis revealed that no recurrence after treatment and transplantation were independent prognostic factors in NPM1 mut AML patients. On the other hand, FLT3-ITD mutation and hemoglobin concentration were associated with RFS and complete remission after treatment was associated with OS in the entire NPM1 mut cohort.

ABSTRACT

Objective:To explore the predictors of upper tract urothelial carcinoma (UTUC) invading muscle.Methods:The preoperative clinical data of 169 patients with UTUC who underwent radical nephroureterectomy (RNU) in the Department of Urology, Second Hospital of Tianjin Medical University from August 2019 to September 2021 were retrospectively collected. The average age of the patients was (67.7±8.3)years. There were 95 male cases (56.2%).15 cases (15.8%) were with diabetes, 46 cases (48.4%) with hypertension, 68 cases (71.6%) with hematuria, 44 cases (46.3%) with renal pelvis tumor, 74 cases (77.9%) with hydronephrosis and 8 cases (8.4%) with multifocality. There were 15 (20.3%), with diabetes, 40(54.1%) with hypertension, 58(78.4%)with hematuria, 32(43.2%) with renal pelvis tumor, 60(81.1%) with hydronephrosis and 2(2.7%) with multifocality among 74 female patients(43.8%), respectively. Patients’ body mass index (BMI) was (24.2±3.2) kg/m 2.The tumor diameter was (3.4±1.8) cm. The average count of neutrophil (NEU) was (4.2±1.7) ×10 9/L, with monocyte (MON) (0.4±0.2) ×10 9/L, platelet (PLT) (237.8±75.3) ×10 9/L and lymphocyte (LYM) (1.7±0.5) ×10 9/L. Neutrophil-to-lymphocyte ratio (NLR) was 2.7±1.4. Mmonocyte-to-lymphocyte ratio (MLR) was 0.3±0.1 and platelet-to-lymphocyte ratio (PLR) was 151.1±59.6. The concentrations of hemoglobin (Hb) and fibrinogen (FIB) were (127.1±18.3) g/L and(3.5±1.0) g/L. Univariate logistic regression analysis was performed on all preoperative data, and a nomogram was established to predict UTUC invading muscle by stepwise regression combined with multivariate logistic analysis. Concordance index (C-index) was used to evaluate the accuracy of the model, and Hosmer-Lemeshow test was used to check the fit. Using 1000 bootstrap resampling to validate the model and draw calibration plot. Receiver operating characteristics (ROC) curves were used to determine the most appropriate cut-off point of the model to predict tumor invasion and evaluate its sensitivity and specificity. Results:In this study, there were 169 cases. Postoperative pathological results showed that 18 cases (10.6%) were of low grade and 151 cases (89.4%) were of high grade. There were 2 patients (1.2%) with pT a stage, 44 patients (26.0%) with pT 1 stage, 37 patients (21.9%) with pT 2 stage, 81 patients (47.9%) with pT 3 stage and 5 patients (3.0%) with pT 4 stage. According to tumor stage, 46 patients were included into non-muscle invasive disease (NMID, pT a/T is/T 1) group and 123 patients were included into muscle invasive disease (MID, pT 2/T 3/T 4) group. Univariate analysis showed that hydronephrosis ( OR=2.919, 95% CI 1.332-6.387, P=0.007) was significantly correlated with MID. Tumor location in ureter ( OR=1.898, 95% CI 0.960-3.800, P=0.067), higher NLR value ( OR=1.313, 95% CI 0.9901.832, P=0.082) and FIB concentration ( OR=1.436, 95% CI 1.008-2.125, P=0.056) might have potential association with MID. Stepwise regression method was used to screen out PLT, FIB and hydronefrosis as the optimal combination for MID prediction. multivariate analysis suggested that PLT decreasing ( OR=0.727, 95% CI 0.548-0.955, P=0.023), FIB increasing ( OR=1.629, 95% CI 1.084-2.552, P=0.025) and hydronephrosis ( OR=2.500, 95% CI 1.111-5.601, P=0.026) were independent predictors of MID.The C-index of the model constructed by the three factors was 0.682, and the P-value of the goodness of fit was 0.778. The ROC curve showed that the optimal cut-off point for the prediction of high-risk MID by the nomogram was 0.627, achieving 39.1% specificity, 88.6% sensitivity and 0.682 area under the curve (AUC). Conclusions:Preoperative decrease of PLT, increase of FIB and hydronephrosis were independent factors for predicting UTUC invading muscle.

ABSTRACT

Objective:To identify the method to reduce X-ray exposure during ablation of atrial fibrillation (AF) by comparing the cryoballoon (CRYO) ablation and remote magnetic navigation (RMN) ablation.Methods:A retrospective analysis was conducted on 144 patients undergoing CRYO ablation (CRYO group) and 121 patients undergoing RMN ablation (RMN group) in our hospital. Entrance surface doses at reference points online, exposure time during procedure and outcomes were analyzed for different types of patients.Results:Compared with the RMN group, the procedure time for the CRYO group significantly decreased [(165.0±23.6), (97.8±18.4) min, t=26.05, P<0.001]. However, the entrance surface dose value [(232.3±130.7), (669.0±387.5) mGy, Z=-12.29, P<0.001] and X-ray exposure time [(8.1±3.1), (23.4±6.2) min, t=-24.57, P<0.001] increased significantly for the CRYO group. No significant difference was found between the two groups in the proportion of maintaining sinus rhythm during follow-up of patients (71.9%, 75.7%, P=0.618). Multiple regression analysis showed that obese patients, patients with non-paroxysmal AF and patients with variant pulmonary veins were associated with an increase in entrance surface dose values in the CRYO group ( t=5.47, 2.23, 3.39, P<0.05). The X-ray exposure time for the three types patients above in the CRYO group also increased ( t=2.87, 3.86, 3.25, P<0.05) in the CRYO group. However, only obese patients in the RMN group had an increase in entrance surface dose value ( Z=-4.15, P<0.001) and no increase in exposure time. For the three types of patients above, there was no significant difference in proportion of maintaining sinus rhythm between the CRYO group and the RMN group during follow-up ( P>0.05). Conclusions:Compared with RMN ablation, the radiation exposure of CRYO AF ablation significantly increased, especially in obese patients, patients with non-paroxysmal AF and patients with pulmonary veins variation. The use of RMN for these types of patients may reduce the radiation exposure without affecting the procedure outcomes.

ABSTRACT

Objective@#To explore the association between negative emotion (depression, anxiety and stress), family intimacy and Internet addiction, so as to provide a basis for the intervention of Internet addiction among junior and senior high school students.@*Methods@#Students were selected by stratified random cluster sampling method from junior high schools and senior high schools from December 2022 to February 2023 in Yixing City, Jiangsu Provicne. A total of 3 026 students completed the questionnaire survey, including the demographic characteristics, Depression, Anxiety and Stress Scale-21 (DASS-21), Family Environment Scale-Chinese Version (FES-CV), and Chinese Internet Addiction Scale Revised (CIAS-R). Bivariate correlation was used to analyzed the association of family intimacy, depression, anxiety, stress, and Internet addiction. Mediating effect model was used to analyzed the mediating effect of negative emotion between family intimacy and Internet addiction.@*Results@#The average score of Internet addiction among junior and senior high school students was (46.26±15.58), and there were statistical differences in the average scores of Internet addiction across different grades ( F=87.15, P <0.01). Depression ( r =0.57), anxiety ( r =0.56), stress ( r = 0.57) were positively correlated with Internet addiction, and family intimacy ( r =-0.34) was negatively correlated with Internet diction ( P <0.01). In the mediating effect model, family intimacy negatively predicted negative emotion ( β =-0.48) and Internet addiction ( β =-0.10), and negative emotion positively predicted Internet addiction ( β =0.45) ( P <0.01). Negative emotion played a partial mediating role between family intimacy and Internet addiction (the mediation value:-1.71, 95% CI =-1.96--1.49, mediation ratio:67.9%, P <0.05).@*Conclusions@#There are associations between negative emotion, family intimacy and Internet addiction among junior and senior school students. Family intimacy indirectly affects Internet addiction mainly through negative emotion. It suggests that family education is in need of attention to reduce the prevalence rate of Internet addiction among junior and senior high school students, especially family intimacy.

ABSTRACT

Objective:To survey the knowledge levels of sudden cardiac death (SCD) prevention among general practitioners (GPs) in Henan province.Methods:From October to November 2019, a questionnaire survey on the knowledge of SCD prevention and treatment was conducted among GP residents participating in the standardized training and assistant GPs taking final examination after training in Henan province. The questionnaire included three dimensions of SCD knowledge: prevention, early diagnosis and first aid. The factors influencing the knowledge levels on SCD prevention were analyzed.Results:A total of 546 questionnaires were distributed and 519 responders (95.1%) completed the questionnaire, including 176 GP residencies and 343 assistant GPs. The age of the respondents was 22-44 (27.91±2.84) years, 234 (45.1%) were males and 285 were females. The overall correct rate of SCD prevention and treatment was (61.46±12.39) %, and the correct rates of prevention, early diagnosis and first aid knowledge were (65.22±17.88)%, (56.58±20.20)% and (62.57±14.60)%, respectively. The overall correct rate and the correct rates of SCD prevention and treatment knowledge among GP residents were higher than those among assistant GPs ( t=10.55, 9.20, 8.62, 3.42, P<0.001); the overall correct rates and the correct rates of SCD first aid knowledge of female GPs were higher than those of males ( t=2.26, 2.13, P=0.025, 0.033); the overall correct rate and the correct rates of each dimensions in age group ≥28 years were higher than those in age group <28 years ( t=4.21, 3.37, 3.20, 2.00, P<0.05). The multivariate logistic regression analysis showed that compared to GP residents,the assistant GPs was the factor influencing the lower levels of the overall knowledge ( OR=0.24, 95 %CI:0.16-0.38, P<0.001), knowledge of prevention ( OR=0.19, 95 %CI:0.10-0.32, P<0.001) and knowledge of early diagnosis ( OR=0.35, 95 %CI: 0.23-0.52, P<0.001);compared to male responders,the females had significantly higher pass rate in SCD first aid knowledge ( OR=1.56, 95 %CI:1.07-2.28, P=0.020). Conclusions:The SCD knowledge levels of the prevention, early diagnosis, and emergency treatment are less satisfactory among GPs in Henan province; it is necessity for targeted training on the weak points of SCD knowledge for GPs.

ABSTRACT

Objective:To investigate the effect of long non-coding RNA 068 (lncRNA 068) on the migration of a melanoma cell line A375, and to explore its mechanism of action.Methods:From December 2015 to November 2020, 21 patients with pathologically confirmed cutaneous melanoma were collected from Department of Dermatology, Affiliated Hospital of Nantong University, and quantitative PCR (qPCR) was performed to determine the expression of lncRNA 068 in melanoma and paracancerous tissues. LncRNA 068 was overexpressed or knocked down via lentiviral transfection in A375 human melanoma cells in the following experiments. Specifically, A375 cells were divided into lentiviral vector (LV) -green fluorescent protein (GFP) group and LV-lncRNA 068 group to be transfected with a GFP-expressing LV and a LV containing lncRNA 068 respectively in the overexpression experiment, and were divided into LV-LacZ short hairpin RNA (shRNA) group and LV-lncRNA 068 shRNA group to be transfected with a LV containing the reporter gene LacZ-specific shRNA and a LV containing the lncRNA 068-targeting shRNA respectively in the low-expression experiment, with the LV-GFP group and LV-LacZ shRNA group serving as the control groups. Transwell and scratch assays were performed to evaluate cell migration, EdU cell proliferation assay and cell counting kit-8 (CCK8) assay to determine the proportion of proliferative cells and cell viability respectively, and immunofluorescence staining was conducted to evaluate epithelial-mesenchymal transformation in the above groups. Lentivirus-transfected A375 cells from the above groups were inoculated into the axillae of BALB/c nude mice, and tumor volume was measured and calculated every 3 days. After 30 days, all mice were sacrificed, and tumor tissues were resected to measure the tumor volume and weight. Cultured B16F10 cells were subcutaneously inoculated into the back and foot of BALB/c nude mice to construct mouse models of subcutaneously transplanted B16F10 melanoma. After 2 weeks, the mice were sacrificed, and qPCR and Western blot analysis were performed to determine the mRNA expression of inflammatory factors in transplanted B16F10 melanoma and paracancerous tissues, and expression of IκB kinase (IKK) /P65 signaling pathway-related proteins, respectively. Comparisons between 2 groups were done by t test, and comparisons of tumor volume and weight at different time points among groups were done by repeated measures analysis of variance. Results:qPCR showed that the relative expression of lncRNA 068 was significantly lower in human melanoma tissues and transplanted B16F10 murine melanoma tissues (0.414 ± 0.109, 0.717 ± 0.041, respectively) than in the corresponding paracancerous tissues (1.050 ± 0.103, 1.011 ± 0.023, t = 19.48, 10.83, respectively, both P < 0.001). Transwell and scratch assays both showed that the cellular migratory ability was significantly lower in the LV-lncRNA 068 group than in the LV-GFP group (both P < 0.01), and significantly higher in the LV-lncRNA 068 shRNA group than in the LV-LacZ shRNA group (both P < 0.05). Immunofluorescence assay showed significantly increased fluorescence intensity of E-cadherin and decreased fluorescence intensity of N-cadherin in the LV-lncRNA 068 group compared with the LV-GFP group (both P < 0.001), but significantly decreased fluorescence intensity of E-cadherin and increased fluorescence intensity of N-cadherin in the LV-lncRNA 068 shRNA group compared with the LV-LacZ shRNA group (both P < 0.05). In vivo tumor formation experiment in nude mice showed that there were no significant differences in the volume or weight of melanoma between the LV-lncRNA 068 group and LV-GFP group (both P > 0.05), as well as between the LV-lncRNA 068 shRNA group and LV-LacZ shRNA group (both P > 0.05). As qPCR and Western blot analysis showed, the mRNA and protein expression of interleukin-10 (IL-10) and claudin-1 in A375 cells were significantly higher in the LV-lncRNA 068 group than in the LV-GFP group (both P < 0.05), but significantly lower in the LV-lncRNA 068 shRNA group than in the LV-LacZ shRNA group (both P < 0.05). Compared with the paracancerous tissues, B16F10 melanoma tissues showed significantly decreased mRNA expression of IL-10 ( P < 0.01), but significantly increased mRNA expression of IL-6 and tumor necrosis factor-α, as well as protein expression of phosphorylated P65 and phosphorylated IKK ( P < 0.01) . Conclusion:Overexpression of lncRNA 068 can inhibit the migration of A375 melanoma cells, and may affect the development of inflammation and inhibit the epithelial-mesenchymal transformation by inhibiting the IKK/P65 signaling pathway.

ABSTRACT

Objective:To survey on the knowledge, attitude and prescribing of benzodiazepines (BZDs) among general practitioners.Methods:A questionnaire survey was conducted in November 2018 among 396 clinicians who participated in the general practice training in Henan Province, including 131 general practitioners (GP group) and 265 non-GPs (non-GP group). The questionnaire included basic information of clinicians, BZDs prescription and training, subjective attitude and knowledge of BZDs.Results:The results of 396 valid questionnaires showed that 55 (13.9%) clinicians had participated in BZDs related training, and 331 (83.6%) clinicians had prescribed BZDs. There was no significant difference in the duration of BZDs continuous use between the GP group and the non-GP group (χ 2= 8.37, P>0.05). The overall score of subjective attitude towards BZDs was low [4(2,6) - 5(3,9)], and the score of BZDs training needs was high [10(8,10)]. Compared to non-GP group, the GP group had lower confidence in BZDs indication [4(2,6) vs. 5(3,6), Z=-2.66, P<0.05 ], the lower ability of judging BZDs addiction [5(2,6) vs. 5(3,7), Z=-2.52, P<0.05], and less understanding of BZDs use guidelines [4(1,5) vs. 4(3,6), Z=-3.05, P<0.05]. In terms of prescription tendency, the GP group was less inclined to prescribe BZDs according to experience [5(2,7) vs. 6(4,8), Z=-3.50, P<0.05]. In the knowledge of BZDs, the total score of GP group was lower than that of non-GP group, the [11(8,12) vs. 11(9,13), Z=-2.06, P<0.05]. The proportion of GPs with drug addiction recognition[66.4%(87/131) vs.77.7%(206/265),χ 2=5.84] and pharmacology knowledge [59.5%(78/131) vs.72.1%(191/265),χ 2=6.32] were all lower than that of non-GPs( P<0.05). Conclusions:General practitioners are lack of knowledge about BZDs and confidence in prescribing BZDs. It is necessary to carry out training on BZDs, especially for addiction and drug effects.

ABSTRACT

Objective:To investigate the effects of different lipid-lowering regimens on blood lipids, endothelial function and safety in patients with unstable angina.Methods:Patients who admitted to Henan Provincial People's Hospital for unstable angina from September 2018 to May 2019 were randomly (random number) divided into the conventional treatment group, intensive statin group and intensive lipid-lowering group. Follow-up was performed at 1, 3, and 6 months after treatment according to the predetermined lipid-lowering regimen. Assessments included lipid profile, liver function, muscle enzymes, hypersensitive C-reactive protein (hs-CRP), endothelial function (reactive hyperemia index, RHI), ischemic events, myalgia, and discontinuation. The differences of the follow-up indicators among the three groups were analyzed.Results:A total of 375 patients were enrolled and randomly divided into three groups, 125 patients in each group. There were no significant differences in demographic data and medication among the three groups. At the 1st month, the low density lipoprotein cholesterin (LDL-C) compliance rate of the intensive statin group was significantly higher than those in the conventional treatment group ( χ2=3.939, P=0.047) and the intensive lipid-lowering group ( χ2=4.63, P=0.031). At the 3rd month, the reductions of LDL-C in the intensive statin group and the intensive lipid-lowering group were significantly better than that in the conventional treatment group( P<0.01). At the 6th month, the reduction rate of LDL-C in the intensive lipid-lowering group was higher than that in the intensive statin group ( q=4.332, P<0.01). At the 1st month, the improvement of hs-CRP and RHI in the intensive statin group was significantly better than that in the conventional treatment group( q=4.133, P<0.05). From the 3rd month of treatment, the incidence of cardiovascular events in the intensive statin group and the intensive lipid-lowering group showed a tendency to decrease compared with the conventional treatment group, but no statistically significant difference was found. At the 6th months of treatment, the withdrawal rates were significantly higher in the intensive statin group and the intensive lipid-lowering group than that in the conventional treatment group (χ 2=4.488, P=0.03 and χ2=5.039, P=0.02). There were no significant differences in the ratio of liver enzyme and muscle enzyme elevation and the incidence of myalgia among the three groups (all P>0.05). Conclusions:Intensive statin therapy can make LDL-C reach the standard in patients with unstable angina pectoris as soon as possible, significantly improve inflammation indicators and endothelial function, and has good safety.

ABSTRACT

Mammalian fertilization begins with the fusion of two specialized gametes, followed by major epigenetic remodeling leading to the formation of a totipotent embryo. During the development of the pre-implantation embryo, precise reprogramming progress is a prerequisite for avoiding developmental defects or embryonic lethality, but the underlying molecular mechanisms remain elusive. For the past few years, unprecedented breakthroughs have been made in mapping the regulatory network of dynamic epigenomes during mammalian early embryo development, taking advantage of multiple advances and innovations in low-input genome-wide chromatin analysis technologies. The aim of this review is to highlight the most recent progress in understanding the mechanisms of epigenetic remodeling during early embryogenesis in mammals, including DNA methylation, histone modifications, chromatin accessibility and 3D chromatin organization.

ABSTRACT

Objective:To explore the relationship between plasma homocysteine level and renal dysfunction in elderly patients with coronary heart disease(CHD).Methods:Eight hundreds and fifty-eight elderly patients with CHD were enrolled at cardiology department of our hospital from January 2015 to July 2017.The patients were divided into the renal insufficiency(RI, defined as an estimated glomerular filtration rate(eGFR)<60 ml/min)group and the non-kidney disease(NKD)group.Using the random number table, the RI group was randomly sub-grouped into the intervention group and the placebo group.The intervention group was treated with folic acid(10 mg/d), vitamin B6(10 mg/d)and vitamin B12(1 mg/d), while the placebo group was given oral placebo.Serum homocysteine(Hcy), creatinine(Cr), blood urea nitrogen(BUN), total cholesterol(TC), triglyceride(TG)and hemoglobin(Hb)were measured by enzyme-linked immunosorbent assay.Pearson correlation was used to analyze the correlations of Hcy with Cr, BUN and eGFR between the RI and NKD groups.Plasma Hcy, Cr, BUN and Hb levels before, and 6, 12 months after treatment were determined and compared between the two subgroups.Staging of renal function was analyzed and clinical effect was evaluated 12 months after treatment in the two subgroups.Results:Serum levels of Hcy, Cr and BUN were higher( t=3.174, 4.857 and 2.644, all P=0.000)and the level of eGFR was lower( t=-2.867, P=0.000)in the RI group than in the NKD group.Plasma Hcy level was positively correlated with plasma levels of Cr and BUN( r=0.308 and 1.214, all P=0.000)and negatively correlated with the eGFR level( r=-0.148, P=0.003). There was no significant difference in plasma Hcy, Hb, Cr and BUN levels between the intervention and placebo group before treatment( P>0.05). At each monitoring time point, serum levels of Hcy, Cr and BUN were decreased continuously in the intervention group( F=314.527, 234.861 and 176.332, P=0.012, 0.000 and 0.006), while plasma Hcy level had no significant change and plasma levels of Cr and BUN were increased continuously in the placebo group( F=196.427, 223.753 and 314.552, P=0.216, 0.000 and 0.002). After 12 months of treatment, plasma levels of Hcy, Cr and BUN were lower in the intervention group than in the placebo group( t=1.284, 0.779 and 2.541, P=0.016, 0.000 and 0.005). There was no significant difference in plasma Hb level between the two subgroups before and after treatment( F=113.764, P=0.182). There was no significant difference in the renal function staging between the two subgroups before treatment( χ2=4.263, P=0.119), while it was improved in the intervention group versus in the placebo group at the end of follow-up( χ2=73.599, P=0.000). Conclusions:The high level of plasma Hcy can be regarded as an independent risk factor for renal insufficiency, and has a correlation with the renal disease progression and prognosis in elderly patients with CHD.

ABSTRACT

Objective:To evaluate the effectiveness and feasibility of health management based on cloud platform for population with high-risk of coronary heart disease (CHD).Methods:In this study, self-control method was used to study the high-risk group of CHD in two community outpatient clinics in Jinshui District, Zhengzhou through cloud platform. One year later, the clinical indicators, the degree of mastering CHD prevention knowledge andthe medicine compliance of the group were evaluated. Finally, the feasibility and acceptance of cloud platform management were evaluated through questionnaire survey.Results:A total of 272 people were enrolled intothe group. After one year of cloud platform management, the blood lipid, uric acid, homocysteine and fasting blood glucose in the group weresignificantly improved (all P<0.05), but the glycosylated hemoglobin was not significantly reduced [(6.4±1.2)% vs.(6.3±1.1)%, P>0.05]. The degree of mastering CHD prevention knowledgewas significantly improved, and the medicine compliance was not significantly improved [(5.0±1.6) vs. (5.0±1.5), P>0.05]. Questionnaire survey showed that 228 (83.8%) of the patients had a high acceptance of cloud platform management, and 208 (76.5%) of the group wanted to continue to use cloud platform for health management. Conclusions:Health management based on cloud platform can improve the clinical index control of the high-risk population of CHD, and help the high-risk population to master the relevant knowledge of CHD prevention. Some functions of cloud platform need to be further improved.

ABSTRACT

Objective:To compare the differences of fluoroscopy time and dose between HIS bundle pacing and right ventricle apex pacing.Methods:This study includes thirty patients undergoing HIS bundle pacing (HIS group) and 32 patients undergoing right ventricular apex pacing (RVA group). The fluoroscopy time and cumulative dose (CD) to patients during surgery were recorded and analyzed.Results:The operation time for patients in HIS group and RVA group were (76.8±13.1) and (66.0±10.8) min ( t=3.386, P<0.001), respectively. The fluoroscopy time was (698.2±113.7) and (293.3±63.9) s ( t=14.709, P<0.001) and the CD were (391.3±70.0) and (162.3±40.5) mGy ( t=13.694, P<0.001) in HBP group and RVA group, respectively. In comparison, the fluoroscopy time and CD for HIS bundle electrode implantation were (501.2±112.3) s and (279.9±65.0) mGy, respectively, significantly higher than in the case of RVA, where the values were (103.4±30.6) s and (57.3±13.8) mGy ( t=15.864, Z=-6.524, P<0.001). Conclusions:Compared with right ventricular apical pacing, the HIS bundle pacing takes longer operation time, leading to higher radiation dose, which should be prudently selected.
