Objective:To explore the current status of lipid-lowering therapy, the distribution of low-density lipoprotein cholesterol (LDL-C) levels and the risk assessment of cardiovascular events recurrence in patients with coronary heart disease (CHD) complicated by hypertension.Methods:This was a cross-sectional study. Patients with CHD combined with hypertension were hospitalized in the Department of Cardiology, General Hospital of Chinese People′s Liberation Army from August 5, 2008 to July 22, 2018 were included, and were divided into standard group and substandard group according to whether LDL-C reached the standard. Study data were obtained from inpatient coronary angiography records and electronic medical records database of Department of Cardiology, General Hospital of Chinese People′s Liberation Army, who used data from the first diagnosis of CHD. Clinical data of the selected patients were collected. Multivariate logistic regression model was used to analyze the associated factors of whether LDL-C reached the standard in CHD patients with hypertension.Results:A total of 18 800 patients were selected from 31 provinces/autonomous regions/municipalities directly under the central government in China, with Beijing accounting for the largest proportion (5 692 patients (30.28%)), followed by Hebei (3 621 patients (19.26%)), Henan (1 837 patients (9.77%)), and Shandong (1 618 patients (8.61%)). Among the selected patients, 1 493 had LDL-C<1.4 mmol/L (standard group), and 17 307 had LDL-C≥1.4 mmol/L (substandard group). Only 1 493 patients (7.94%) had LDL-C<1.4 mmol/L. There were 4 518 patients (24.03%), 4 366 patients (23.22%), 6 924 patients (36.83%) and 1 499 patients (7.97%) with LDL-C for 1.4-<2.0, 2.0-<2.5, 2.5-<3.8 and≥3.8 mmol/L levels, respectively. 17 855 patients (95.15%) were treated with statins, but only 1 334 patients (7.10%) were treated with statins and ezetimibe. Of the selected patients, 4 986 patients (26.52%) were at low risk, 6 515 patients (34.65%) were at intermediate risk, and 7 299 patients (38.82%) were at high risk. The combined lipid-lowering treatment rates of statin and ezetimibe in the middle-and high-risk patients were 7.43% (484/6 515) and 7.48% (546/7 299), respectively. The results of multivariate logistic regression analysis showed that increasing age, male, diabetes mellitus, stroke, and history of percutaneous coronary intervention (PCI) were positively associated with LDL-C standards in patients with CHD and hypertension, whereas obesity and acute myocardial infarction (AMI) were negatively associated with LDL-C standards (all P<0.01). Conclusions:The rate of achieving the standard LDL-C in patients with CHD combined with hypertension was low in China. Although the majority of patients had received moderate-intensity statin therapy, the proportion of statin-treated patients combined with ezetimibe was extremely low. The proportion of high-risk patients with recurrent cardiovascular events was higher in patients with CHD and hypertension in China, whereas the proportion of such patients receiving statin combined with ezetimibe lipid-lowering therapy was lower. This study also found that increasing age, male, diabetes mellitus, stroke, and history of PCI were positively associated with LDL-C standards, while obesity and AMI were negatively associated with LDL-C standards in patients with CHD and hypertension.

Objective To understand the current situation of human brain donation in Hebei Province by analyzing the basic information of Human Brain Bank samples of Hebei Medical University in order to provide basic data support for subsequent scientific research.Methods The samples collected from the Human Brain Bank of Hebei Medical University were analyzed(from December 2019 to February 2024),including gender,age,cause of death,as well as quality control data such as postmortem delay time,pH value of cerebrospinal fluid and and RNA integrity number and result of neuropathological diagnosis.Results Until February 2024,30 human brain samples were collected and stored in the Human Brain Bank of Hebei Medical University,with a male to female ratio of 9∶1.Donors over 70 years old accounted for 53％.Cardiovascular and cerebrovascular diseases(36.67％)and nervous system diseases(23.33％)accounted for a high proportion of the death causes.The location of brain tissue donors in Shijiazhuang accounted for 90％donations,and the others were from outside the city.The postmortem delay time was relatively short,90％within 12 hours and 10％more than 12 hours.69.23％of the brain samples had RNA integrity values greater than 6.Cerebrospinal fluid pH values ranged from 5.8 to 7.5,with an average value of 6.60±0.45.Brain weights ranged from 906-1496 g,with an average value of(1210.78±197.84)g.Three apolipoprotein E(APOE)alleles were detected including five genotypes(ε2/ε3,ε2/ε4,ε3/ε3,ε3/ε4,ε4/ε4).Eleven staining methods related to neuropathological diagnosis had been established and used.A total of 12 cases were diagnosed as neurodegenerative diseases(including Alzheimer's disease,Parkinson's disease,multiple system atrophy,corticobasal degeneration and progressive supranuclear palsy,etc.),accounting for 40％donated brains.The comorbidity rate of samples over 80 years old was 100％.Conclusion The summary and analyses of the data of brain donors in the Human Brain Bank of Hebei Medical University can reflect the current situation of the construction and operation of the brain bank in Hebei Province,and it can also be more targeted to understand and identify potential donors.Our information can provide reference for the construction of brain bank and provides more reliable materials and data support for scientific research.

Background::The clinical characteristics of patients with the comorbidities of hypertension and coronary artery disease (HT-CAD) and atrial fibrillation (AF) are largely unknown. This study aimed to investigate the prevalence of AF in patients with HT-CAD and clinical characteristics of patients with both HT-CAD and AF.Methods::This cross-sectional study was conducted in Chinese People’s Liberation Army General Hospital in Beijing, China, and included 20,747 inpatients with HT-CAD with or without AF from August 2008 to July 2018. We examined the overall prevalence, clinical characteristics, comorbidity profiles, treatment patterns, and blood pressure (BP) control of patients with both HT-CAD and AF. Multivariate logistic regression was used to investigate the associations of cardiovascular risk factors with AF in patients with HT-CAD.Results::The overall prevalence of AF in patients with HT-CAD was 4.87% (1011/20,747), and this increased with age; to be specific, the prevalence in women and men increased from 0.78% (2/255) and 1.02% (26/2561) at the age of <50 years to 8.73% (193/2210) and 10.28 % (298/2900) at the age of ≥70 years, respectively. HT-CAD patients who had AF had a higher prevalence of cardiovascular-related comorbidities than those without AF. Multivariate logistic regression showed that age, gender (male), body mass index, heart failure, and chronic kidney disease were independently associated with the risk of AF in patients with HT-CAD. For those with both HT-CAD and AF, 73.49% (743/1011) had a CHA 2DS 2-VASc score of ≥4, and only about half of them had the BP controlled at <140/90 mmHg, which indicated a high risk of thromboembolism and stroke. The use of oral anticoagulation increased during the study period (10.00% [20/200] in 2008 to 2011 vs. 30.06% [159/529] in 2015 to 2018, P < 0.01), but remained at a relatively low level. Conclusions::AF is highly prevalent among patients with HT-CAD. Patients with both HT-CAD and AF have a higher prevalence of cardiovascular-related comorbidities, lower BP control rate, and lower use of oral anticoagulation.

Objective To determine the influence of abiraterone acetate (AA) on neuroendocrine differentiation (NED) in metastatic castration-resistant prostate cancer (mCRPC) and the prognostic predicting value of the serum NED markers in mCRPC patients treated with AA.Methods We conducted an analysis in 115 chemotherapy-naive mCRPC patients who were treated with chemotherapy in Renji hospital from 2013 to 2017.The median age was 70,ranged from 65 to 76 years old.The median CgA,NSE and PSA levels were 101.1 ng/ml (78.5-150.0 ng/ml),13.4 ng/ml (10.5-17.6 ng/ml) and 38.8 ng/ml (11.2-123.2 ng/ml),respectively.Among them,48 cases were classified as the group without AA treatment.The other 67 cases were classified as group after AA failure.In group without AA treatment,the median CgA,NSE and PSA levels were 109.1 ng/ml(80-151.5 ng/ml);13.8 ng/ml(10.8-18.2 ng/ml) and 39.2 ng/ml (8.6-200 ng/ml),respectively.In group after AA failure,the median CgA,NSE and PSA levels were 105.4 ng/ml(78.8-175.5 ng/ml),13.8 ng/ml(10.8-17.6 ng/ml) and 39.0 ng/ml(8.4-219.8 ng/ml),respectively.In the group with serial evaluation of NED markers during AA treatment,the median serum CgA,NSE levels at baseline were 115.9 ng/ml(90.1-201.5 ng/ml),13.3 ng/ml (10.4-18.1 ng/ml),respectively.The endpoints were PSA PFS(progression-free survival) and radiographic PFS (rPFS).Results In 34 patients with serial evaluation,serum NED markers level in 19 patients increased after the failure of AA treatment.Median serum CgA and NSE levels were 115.9 ng/ml(90.1-201.5 ng/ml)and 13.25 ng/ml (10.37-18.14 ng/ml) at baseline.Median serum CgA and NSE levels were 129.6ng/ml (75.5-230.5 ng/ml) and 14.7 ng/ml (11.8-19.1 ng/ml) after 6 months treatment,respectively.The median serum CgA and NSE levels were 130.4 ng/ml (95.7-205.7 ng/ml) and 15.2 ng/ml(12.4-18.7 ng/ml) at the time of failure of AA treatment,respectively.There was no significant difference of NED markers between baseline and failure of AA treatment (P =0.243).In logistic univariate analysis,AA treatment and its duration were not independent factors influencing NED(P =0.30;P =0.52).Compared with the NED markers elevation group in the first 6 months of AA treatment and baseline supranormal NED markers group,the NED markers decline group(PSA PFS(17.1 vs.10.4 months,P ＜ 0.001) and rPFS (17.0 vs.10.4 months,P =0.003)) and baseline normal NED markers group(PSA PFS(14.1 vs.9.5 months,P =0.001) and rPFS(16.4 vs.10.5 months,P ＜ 0.001)) has a longer median PSA PFS and rPFS respectively.In multivariate Cox analysis,baseline NED markers level and NED markers variation during the first 6 months of AA treatment remained significant predictors of rPFS(P ＜ 0.05),and PSA-PFS (P ＜ 0.05).Conclusions We found there was heterogeneity in changes of NED markers in different mCRPC patients during AA treatment,and AA might not significantly lead to progression of NED of mCRPC in general.Serial CgA and NSE evaluation might help clinicians guide clinical treatment of mCRPC patients.Serum NED markers elevation during the first 6 months of AA treatment and elevated baseline NED markers levels indicated poor prognosis in mCRPC treated with AA.

Objective To evaluate the effect of early high -volume hemofiltration in the treatment and prognosis of post -resuscitation syndrome( PRS).Methods A total of 44 patients wiht PRS were ran-domly divided into the trial group and the control group, and all patients were treated by conventional treatment.The patients in the trial group were treated by early high-volume hemofiltration within 6 h, while the patients in the control group were treated by high-volume hemofiltration after 6 h.Acute physiology and chronic health evaluation ( APACHEII) , multiple organ dysfunction syndrome evaluation ( MODS ) , C -reactive protein(CRP), procalcitonin(PCT), dopamine dosage, mean arterial pressure(MAP), and oxygenation index were recorded.Results The APACHE Ⅱ score, MODS score, serum CRP and PCT level improved and dopamine dosage decreased after treatment in two groups compared with those before treatment (P<0.05), but the parameters in trial group were significantly lower than those in control group ( P<0.05) , and MAP and oxygenation index in the trial group were significantly higher than those in the control group ( P <0.05 ) . Conclusion Early high-volume hemofiltration is effective in the treatment and prognosis of PRS with positive significance.

This study was purposed to evaluate the effectiveness and safety of autologous cytokine induced killer (CIK) cells combined with chemotherapy in treatment of elderly patients with acute myeloid leukemia. Peripheral blood mononuclear cells (PBMNC) were isolated from 5 elderly patients with acute myeloid leukemia, and then augmented by priming with interferon gamma (IFN-γ) followed by IL-2 and monoclonal antibody (mAb) against CD3. The autologous CIK cells thus obtained were infused back to individual patients, 28 days as one cycle. The changes in cellular immune function, incidence of infection, independence of hematoglobin or blood transfusion, and progression of disease were observed and assessed before and after therapy. The results showed that the 46 cycles of CIK cell infusion were performed for 5 patients, no adverse reaction was observed in these patients. The percentages of CD3(+), CD3(+)CD8(+) and CD3(+)CD56(+) increased significantly (P < 0.05), The therapy of CIK could significantly reduce the incidence of infection (P < 0.05) and shorten the time of high fever in AML patients (P < 0.05). CIK also could reduce the volume of erythrocyte infusion to maintenance hematoglobin level (P < 0.05). We found that although CIK could not change the outcome of AML, the combination of CIK and chemotherapy could control patients' condition and prolong their survival during the development and end stage of AML. It is concluded that autologous CIK cells combined with chemotherapy is safe and efficacious for the elderly patients with acute myeloid leukemia.

The purpose of this study was to explore the clinicopathological features, therapy and prognostic factors of elderly patients with non-Hodgkin's lymphoma (NHL). The clinical data including general clinical characteristics, pathological features, chemotherapy selection and treatment response of 30 patients with NHL in our hospital from January 2003 to December 2012 were analyzed retrospectively. The survival was analyzed by using Kaplan-Meier methods, and the prognosis was evaluated by COX regression multivariate analysis model. The clinical parameters selected include age, Ann Arbor stage, international prognostic index (IPI), B symptom and lactate dehydrogenase (LDH) levels. The results showed that all the patients suffered from underlying disease, and the cardiovascular disease (hypertension, coronary heart disease, arrhythmia) is the most common, and minority (8/30) combined with secondary tumor, the 63% (19/30) cases had B symptoms at diagnosis. only 2 cases were diagnosed as T-cell lymphoma; the 93% (28/30) cases combined with B-cell lymphoma, 57% (17/28) of them combined with diffuse large B-cell lymphoma. Ann-Arbor stage ≤ IIwas 37% (11/30);10(37%) patient's IPI score was ≤ 2, and 67% (20/30) was scored 3-5; 13(43%) patient's serum LDH level was abnormal. Modified R-CHOP chemotherapy was given individually on the basis of clinical features. The patients achieved complete remission, partial remission, stable disease, or progressive disease accounted for 14 (46.7%), 13 (43.3%), 1 (3.3%), and 2 (6.7%), respectively; the total reaction rate was 90% after 4 cycles of chemotherapy; the overall survival (OS) rate at 1 and 2 years was 73.3% and 43.3%, and progression-free survival (PFS)rate at 0.5 and 1 years was 62.2% and 54.9%; multivariate analysis by COX regression showed that B symptoms and Ann-Arbor stage were independent factors (P = 0.014, 0.039; RR = 6.678, 4.939, respectively) affecting the OS of elderly NHL, and IPI score affected PFS independently. It is concluded that elderly patients with NHL usually are of late stage at newly diagnosis and have suffered from underlaying diseases. Besides strengthening supportive treatment, modified R-CHOP chemotherapy should be given individually according to different prognosis. B symptoms and Ann-Arbor stage >II are indicators for poor prognosis of elderly NHL.

OBJECTIVETo compare the penetration abilities of resin infiltration into proximal lesions in primary molars with those of adhesive in vitro.

METHODSThirty-two extracted or exfoliated primary molars showing proximal white spot lesions were selected. Roots of the teeth were removed, and the crowns were cut across the white spot lesions perpendicular to the surface. Cut surfaces were examined (by stereo microscopy) and classified with respect to histological lesion extension (C1-C4): lesions confined to the outer half on enamel (C1), lesions confined to the inner half on enamel (C2), lesions confined to the outer half on dentin (C3), lesions extending into the inner half of dentin (C4). Corresponding lesion halves were etched for 120 s with 15% hydrochloric acid gel and were subsequently treated with either adhesive or resin infiltration. Specimens were observed with laser scanning confocal microscope (LSCM) in dual fluorescence mode. In confocal microscopic images, lesion depth and penetration depth of the resin infiltration or the adhesive in corresponding halves were measured, and penetration percentages were calculated respectively. Differences of the data between two groups were analyzed by Wilcoxon signed rank test. Variations of histological caries extensions were detected with Kruskal-Wallis H test.

RESULTSAt the same grading level (C1-C3) in histological caries extension, penetration depths of the resin infiltration group and the adhesive group were 240 (230, 260) µm vs 190 (150, 210) µm, 405 (300, 523) µm vs 180 (160, 200) µm, and 590 (430, 640) µm vs 180 (160, 200) µm respectively. There was significant statistical difference in the data between two groups (P < 0.05). Statistically significant difference in penetration depths of the resin infiltration group (at C1-C3) were found (P < 0.01). At the same grading level (C1-C3) in histological caries extension, percentage penetrations of the resin infiltration group and the adhesive group were [100.0% (96.2%, 100.0%)], [99.1% (95.7%, 100.0%)], [82.0% (81.1%, 92.2%)] and [79.2% (68.4%, 87.5%)], [41.8% (29.1%, 74.5%)], [30.2% (29.2%, 39.6%)], respectively. The difference between the above data was also significant (P < 0.05). Percentage penetrations of the resin infiltration group at C1 and C2 level was higher than those at C3 level (P < 0.05).

CONCLUSIONSThe resin infiltration is capable of penetrating almost completely into proximal lesions in primary molars.

The function of immune system degenerates in an aging-dependent manner and this results in immunosenescence. Human immune system includes two parts: genetic/innate immunity and adaptive immunity. The former is involved in monocytes, nature killer cells, and dendritic cells, the later is involved in acquired B and T lymphocytes. During the aging of immunity system, the both parts of immunity are damaged to some degree. Generally, innate immunity seems well-retained and the acquired immunity is degenerative seriously with aging. Immunocyte senescence is closely related to the elderly decreased ability to control infectious disease, cancer and to their generally poor response to vaccination. This review summarized the research progress on immunosenescence characteristics in aged phase.

This study was purposed to evaluate the safety and curative effect of autologous cytokine induced killer cells (CIK) combined with low-dose IL-2 regimen containing immune enhancement of thymic peptide on elderly patients with B-cell chronic lymphocytic leukemia (B-CLL). Thymic peptide α1 was subcutaneously given as the immunoenhancement agent at a dose of 1.6 mg/d, 14 days as one cycle. Peripheral blood mononuclear cells (PBMNC) from 5 patients with B-CLL were isolated once a week to induce ex vivo CIK cells through culture in the context of interferon (IFN)-γ, interleukin (IL)-2 and anti-CD3 monoclonal antibody. The PBMNC were separated from patients before and after 14 days as one cycle of thymic peptide α1 administration. Parameters of amplification ability, effector cells quantity, lymphocyte subgroups percentage and antitumor cytotoxicity were compared before and after thymic peptide administration. The 5 patients were treated with CIK cells combined with low-dose IL-2 regimen immediately after injection of thymic peptide α1. The CIK cells plus low-dose IL-2 regimen containing thymic peptide enhancement was defined as: thymic peptide α1 1.6 mg/d was subcutaneously administered once every other day; (4 - 6) ×10(9) of CIK cells were transfused followed by IL-2 subcutaneous administration of 1 mU/d on days 1-10, 28 days as one cycle. Clinical evaluation parameters including cellular immunity function, CLL related biomarkers, disease state and infectious frequency and degree were investigated before and after CIK cells infusion puls IL-2. The results showed that the amount of amplified CIK cells, the percentage and amplification times of effector cells and antitumor cytotoxicity more significantly increased after thymic peptide α1 treatment than before its use (P < 0.05). The total 46 cycles of CIK cells infusion plus IL-2 were completed in the 5 CLL patients. No adverse reaction was observed. After treatment of CIK cells plus IL-2, the general conditions of 5 CLL patients were to different extent improved. Simultaneously, percentages of CD3(+), CD3(+)CD8(+), and CD3(+)CD56(+) cells in peripheral blood remarked by raised (P < 0.05), the serum level of β2 microglobulin was significantly declined (P < 0.05), and the frequency and degree of infection was also decreased (P < 0.05). Following CIK cells plus IL-2 therapy, the transformation of disease state from partial remission (PR) to complete remission was seen in 3 patients, from stable disease (SD) to PR in 1 patient, and from progress of disease to SD in 1 patient. It is concluded that the regimen of autologous CIK cells combined with low-dose IL-2 containing immune enhancement of thymic peptide is safety and effective for the treatment of elderly patients with B-CLL.
