Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective: To evaluate the clinical effect of clear aligners in the anterior region in non-extraction cases by establishing a three-dimensional model of crown-root fusion to guide clinical application. Methods: Eleven patients visiting the orthodontic department of Xuzhou Stomatological Hospital from December 2020 to December 2021 were collected, and the orthodontic plan was designed using Maestro 3D Dental Studio scheduling software to obtain the expected three-dimensional model of the patient's orthodontic treatment result. CBCT, intraoral scan, and 3D reconstruction software were used to create a postoperative model of the patient. The crown and root data were aligned in Geomagic Studio 2014, and differences in torque and axial inclination between the actual model after treatment and the predicted model of the anterior teeth before treatment were compared in 3-matic. Results: The actual torque angles of the anterior teeth were all smaller than the predicted angles before treatment, with the highest realization rate of 77.55% for lateral incisors and the lowest of 60.70% for central incisors; the actual axial inclination angles of the anterior teeth were also smaller than the predicted angles before treatment, with the highest realization rate of 81.49% for central incisors and the lowest of 74.95% for cuspids. Conclusion A digital model of crown-root integration based on a combination of 3D reconstruction and intraoral scanning techniques is advantageous in assessing the efficacy of clear aligners. In non-extraction cases with clear aligner, the efficiency of movement is higher for small areas of the anterior region.

To investigate the correlation between serum Brain-derived neurotrophic factor （BDNF），Val66Met gene polymorphism and clinical symptoms in patients with newly diagnosed Parkinson’s disease （PD）. Methods A total of 62 early PD patients and 46 healthy controls were collected from Ningbo First Hospital. General demographics，Hamilton Anxiety Scale （HAMA），Hamilton Depression Scale （HAMD），Orthostatic Hypotension （OH） or not，serum BDNF levels，Val66Met genotype were examined in all subjects，duration of disease，Hoehn-Yahr （HY） Rating Scale，Unified Parkinson’s Disease Rating Scale motor scores （UPDRS-Ⅲ），symptom classification （tremor type，rigid type or mixed type） were also assessed in patients. Results PD patients had significantly higher HAMA，HAMD scores，incidence of OH and lower BDNF levels than controls，there was no significant difference in the distribution of Val66Met gene polymorphism between the two groups. Multiple linear regression revealed that BDNF levels were negatively associated with HAMA （P=0.014） and HAMD （P=0.013） scores in PD patients，however，no significant correlation were found between Val66Met polymorphism and clinical symptoms. Conclusion Evident non-motor symptoms can occur in early PD patients，serum BNDF levels were correlated with the degree of anxiety and depression in patients，and Val66Met gene polymorphism may not play an important role in the course of disease.

OBJECT IVE To study the effects of ergosterol peroxide derivatives EP-3P on the proliferation ，migration and invasion of human tripe negative breast cancer cell MDA-MB- 231，and to provide reference for the development of breast cancer related drugs. METHODS MTT assay was adopted to detect the proliferation of MDA-MB- 231 cells after treated with 0（blank control），1.25，2.5，5，10，20，40 μmol/L EP-3P for 24，48 and 72 h. Wound healing assay and Transwell chamber method were adopted to detect the migration and invasion ability of MDA-MB- 231 cells after treated with 0（blank control ），5，10，20 EP-3P for 24 h. The apoptosis and cell cycle distribution were detected by flow cytometry. Western blot assay was used to detect the expressions of B-cell lympho ma-2（Bcl-2），Bcl-2 associated X protein （Bax），caspase-3，cleaved-caspase-3，cytochrome C （Cyt-C），matrix metalloproteinase- 2（MMP-2）and MMP- 9. RESULTS Compared with blank control group ，2.5，5，10，20，40 μmol/L EP-3P could significantly increase the inhibitory rate of cell proliferation （P＜0.05 or P＜0.01）in a dose and time- dependent manner. After 24 h treatment of EP- 3P（10，20 μmol/L），the rate of cell migration and the number of invasive cells were decreased significantly （P＜0.01），and cell was arrested at G 2/M stage （P＜0.05 or P＜0.01）；the apoptotic rate was increased significantly （P＜0.05）；the protein expressions of Bax ，Cyt-C and cleaved-caspase- 3 were upregulated significantly ， while those of Bcl- 2，caspase-3，MMP-2 and MMP- 9 were downregulated significantly （P＜0.01）. CONCLUSIONS EP-3P can inhibit the proliferation ，migration and invasion of human tripe negative breast cancer cells MDA-MB- 231 through mitochondrial mediated endogenous caspase pathway ，and induce the apoptosis of cells .

Objective:To investigate the prevalence and risk factors of diabetic peripheral artery disease (PAD) in patients with type 2 diabetes mellitus (T2DM) managed in primary health care in China.Methods:A total of 2 528 T2DM patients were selected using a two-stage cluster random sampling method based on the baseline survey of the "China Diabetic Foot Prevention Model Project." The study was conducted in 2015 among T2DM patients in 8 primary healthcare centers in Changshu county and Jiang'an district of Wuhan, China. Data collection methods included a questionnaire, body measurement, and blood glucose detection. The Ankle-Brachial Index (ABI) is the most widely used noninvasive vascular test. A binary logistic regression model was used to analyze the influence factors.Results:The prevalence of PAD was 11.2% among the diabetic patients managed in primary health care in the two cities. The prevalence of PAD under 55 years old, 55- years old, 65- years old, and ≥75 years old were 7.8%, 6.0%, 12.9% and 22.5%, respectively. Multivariate stepwise logistic regression identified influence factors included older age, higher education level, smoking, drinking, postprandial glucose uncontrol, and prior myocardial infarction or angina. Compared to age <55 years, the odds ratio for PAD were 0.74 for 55- years (95% CI: 0.43-1.28), 1.72 for 65- years (95% CI: 1.05-2.81), 3.56 for 75 years and above (95% CI: 2.07-6.11), respectively. Compared to patients with education in primary school and below, the odds ratio was 1.37 (95% CI: 0.97-1.94), 2.48 (95% CI: 1.73-3.55), 1.99 (95% CI: 1.26-3.13) for those with education levels of junior high school, senior high school, and college, respectively. Current smoking ( OR=1.49, 95% CI: 1.02-2.17), current drinking ( OR=0.45, 95% CI: 0.28-0.71), postprandial glucose uncontrol (2 h postprandial plasma glucose >10.0 mmol/L: OR=1.72, 95% CI: 1.22-2.43), and prior myocardial infarction or angina ( OR=2.32, 95% CI: 1.50-3.61) were influencing factors of PAD. Conclusions:Despite the high prevalence of PAD in diabetes managed in primary health care; multiple risk factors are not effectively aware of and under control. It is urgent to promote ABI screening and standardized management for diabetes, especially in primary health care.

Coronavirus disease 2019(COVID-19),which is caused by SARS-CoV-2,varies with regard to symptoms and mortality rates among populations.Humoral immunity plays critical roles in SARS-CoV-2 infection and recovery from COVID-19.However,differences in immune responses and clinical features among COVID-19 patients remain largely unknown.Here,we report a database for COVID-19-specific IgG/IgM immune responses and clinical parameters(named COVID-ONE-hi).COVID-ONE-hi is based on the data that contain the IgG/IgM responses to 24 full-length/truncated proteins corresponding to 20 of 28 known SARS-CoV-2 proteins and 199 spike protein peptides against 2360 serum samples collected from 783 COVID-19 patients.In addition,96 clinical parameters for the 2360 serum samples and basic information for the 783 patients are integrated into the database.Furthermore,COVID-ONE-hi provides a dashboard for defining samples and a one-click analysis pipeline for a single group or paired groups.A set of samples of interest is easily defined by adjusting the scale bars of a variety of parameters.After the"START"button is clicked,one can readily obtain a comprehensive analysis report for further interpretation.COVID-ONE-hi is freely available at www.COVID-ONE.cn.

Emergency surgery was performed after emergency nucleic acid testing and preoperative examing. Postoperatives were carried to a single room in the ICU for isolation until COVID-19 was excluded, nucleic acid testing and reexamination of pulmonary CT were performed if they were fever during hospitalization.All medical personnel involved in the operation and perioperative management took three levels of protection and medical observation.Results:There were 5 cases of type A1 in the aortic root, 2 cases of type A2, 22 cases of type A3, 2 cases of simple arch, 27 cases of complex type (Sun's classification).12 cases of Bentall, 2 cases of Wheats, 15 cases of ascending aorta replacement, 14 cases of aortic valve repair, 25 cases of aortic arch replacement, 23 cases of trunk stents, 2 cases of hybridization, 6 cases of concurrent coronary artery bypass grafting, and 2 cases of tricuspid valvuloplasty.In the whole group, 1 case of COVID-19 was confirmed and 1 was suspected.The time of cardiopulmonary bypass was(224.00±21.14)min, the blocking time was(146.17±18.75)min, the postoperative ventilator assisted(65.07±10.36)h, the hospitalization time was(27.03±5.64)days, there were no hospitalized deaths, 4 cases of postoperative liver function damage, 6 cases of acute renal function damage, and 7 of pulmonary infection.None of the medical staff involved in the operation and perioperative management were infected with COVID-19.Conclusion:During the period of major infectious diseases, the admission and treatment procedures of critical and severe patients should be standardized, and the control of nosocomial infection should be strengthened. Emergency surgery is an effective means to rescue type A active vein interlayer, and the safety of protecting medical staff is guaranteed.

OBJECTIVE： To observe the effects of nicorandil on vascular endothelial function and angina pectoris recurrence in patients with unstable angina pectoris after percutaneous coronary intervention （PCI）. METHODS： Totally 195 patients with unstable angina pectoris were collected from Sichuan Provincial People’s Hospital during Jan. 2016-Mar. 2018， and then divided into control group （97 cases） and observation group （98 cases） according to random number table. Both groups received PCI， and then given basic treatment as Enoxaparin sodium injection， Isosorbide mononitrate sustained-release tablets， Aspirin enteric-coated tablets， Clopidogrel sulfate tablets and Atorvastatin calcium tablets after PCI. Observation group additional received Nicorandil tablet 5 mg， tid， on the basis of control group. Both groups were treated for 6 months. The levels of vascular endothelial function related indexes （FMD， ET-1， NO）， myocardial injury markers （cTnⅠ， CK-MB） and inflammatory factors （hs-CRP） were observed before and after PCI. The recurrent angina pectoris， the occurrence of MACE and ADR were recorded. RESULTS： 6 patients of control group and 4 patients of observation group withdrew from the study. One day before operation， there was no significant difference in the levels of vascular endothelial function， myocardial injury markers or inflammatory factors between 2 groups （P＞0.05）. One day after operation， the levels of FMD and NO in both groups decreased significantly， while the levels of ET-1， cTnⅠ and CK-MB increased significantly （P＜0.05）. The levels of FMD and NO were increased significantly in the 1st and 6th months after surgery， and the observation group was significantly higher than the control group； the levels of ET-1， cTnⅠ， CK-MB and hs-CRP were decreased significantly， and the observation group was significantly lower than the control group （P＜0.05）. The incidence and times of recurrent angina pectoris， duration， the proportion of grade Ⅲ angina pectoris and total incidence of MACE in observation group were significantly lower， less or shorter than control group （P＜0.05）. There was no statistical significance in total incidence of ADR between 2 groups （P＞0.05）. CONCLUSIONS： Additional use of nicorandil can improve vascular endothelial function， relieve the myocardial injury and inflammatory response， reduce the occurrence of recurrent angina pectoris and MACE after PCI and doesn’t influence the safety of routine treatment.
