Résumé
BACKGROUND@#Epidemiological surveys on heart failure (HF) in Chinese community are relatively lacking. This study aimed to estimate the prevalence and incidence of HF among community residents in southern China.@*METHODS@#Baseline data of this prospective study was collected from 2015 to 2017 among 12,013 permanent residents aged ≥ 35 years in Guangzhou, China. The same survey process was carried out for individuals aged ≥ 65 years after a three-year follow-up.@*RESULTS@#The overall prevalence of HF in community residents aged ≥ 35 years was 1.06%. Male had significantly higher risk of HF prevalence [odds ratio (OR) = 1.50, P = 0.027]. The gender-adjusted risk of HF was 1.48 times higher per 10 years aging. HF prevalence was statistically associated with atrial fibrillation, valvular heart disease, hypertension and chronic obstructive pulmonary disease after adjusting for age and gender (OR = 8.30, 5.17, 1.11, 2.28, respectively; all P < 0.05). HF incidence in individuals aged ≥ 65 years were 847 per 100,000 person-years. Baseline atrial fibrillation, valvular heart disease, and diabetes mellitus were risk factors for HF incidence for individuals aged ≥ 65 years adjusting for age and gender (OR = 5.05, 3.99, 2.11, respectively; all P < 0.05). Besides, residents with new-onset atrial fibrillation and myocardial infarction were at significantly higher risk of progression to HF (OR = 14.41, 8.54, respectively; all P < 0.05).@*CONCLUSIONS@#Both pre-existing and new-onset cardiovascular diseases were associated with HF incidence in southern China. Management of related cardiovascular diseases may be helpful to reduce the incidence of HF.

AIM:To observe the changes of macular morphology and microcirculation in myopic maculopathy(MM), and investigate theirs correlation and effects on vision.METHODS: Case-control study. A total of 165 patients(189 eyes)with high myopia and 154 healthy volunteers(154 eyes)from October 2016 to December 2018 were selected. According to the classification of Meta-analysis for pathologic myopia(META-PM), participants were divided into M0 group(category 0, 41 eyes), M1 group(category 1, 53 eyes), M2 group(category 2 and 3, 52 eyes), and myopic choroidal neovascularization(mCNV)group(43 eyes). All participants underwent optical coherence tomography angiography(OCTA)examination. Morphological and microcirculation parameters of retina at different layers were compared between groups. Pearson correlation was used to assess the correlation between morphological and microcirculation parameters. Correlations between vision and other parameters were analyzed using multiple linear regression analysis.RESULTS:Foveal full retinal thickness(FRT)and outer retinal thickness(ORT)were all lower in M0, M1 and M2 groups than those of control group(all P<0.01). Foveal superficial capillary plexus vessel density(SVD)and deep capillary plexus vessel density(DVD)were all lower in M2 and mCNV groups than those of the control group(all P<0.01). Parafoveal FRT and ORT were all lower in M0, M1, M2 and mCNV groups than those of the control group(all P<0.01). Parafoveal inner retinal thickness(IRT), SVD and DVD were all lower in M2 and mCNV groups than those of the control group(all P<0.01). Subfoveal choroidal thickness(SFCT)and choroid capillaries vessel density(CVD)were all lower in M0, M1, M2 and mCNV groups than those of the control group(all P<0.01). Foveal vessel density of retina and choroid were positively correlated with its thickness in patients with MM without CNV(all P<0.05). Multivariate analysis showed that axial length(AL), diffuse or patchy chorioretinal atrophy were influencing foctors of best corrected visual acuity(BCVA; all P<0.01).CONCLUSION:Retinal morphological changes precede microcirculation changes in MM. Most of all, ORT changes precede IRT changes. Foveal vessel density of retina and choroid were positively correlated with its thickness. The main influencing factors of BCVA were AL and types of MM.

AIM: To observe the postoperative changes in macular morphological structure and blood flow density of patients with idiopathic macular epiretinal membrane(IMEM)by optical coherence tomography angiography(OCTA), and explore their correlation with visual acuity.METHOD: Prospective study. A total of 45 cases(45 eyes)with IMEM admitted to our hospital from January 2020 to July 2021 were included. The best corrected visual acuity(BCVA), central macular area thickness(CMT), foveal avascular zone(FAZ)area and changes in blood flow density of superficial capillary plexus(SCP)were observed at 1mo, 1, 3 and 6mo before and after operation.RESULT: The BCVA at 1wk after operation had no significant change compared with preoperative data(P>0.05), while it was improved at other time points(P<0.05). The CMT measured at 1wk after operation was thickened significantly(P<0.05), while it was significantly decreased at 1mo, 3mo and 6mo after operation(P<0.05). The FAZ area measured at 1wk and 1mo after operation had no significant change(P>0.05), while it was significantly enlarged at 3 and 6mo after operation(P<0.05). The SCP measured at 1wk, 1 and 3mo after operation had no significant change(P>0.05), while it was significantly decreased at 6mo after operation(P<0.05). BCVA measured at 3 and 6mo after operation was positively correlated with CMT(r=0.457, 0.615, P=0.032, 0.012).CONCLUSION: The visual acuity of patients with IMEM recovered quickly within 1mo after operation, and then it tended to be stable. However, the recovery of macular foveal morphology and blood flow distribution was slower than that of visual acuity, and there was no obvious correlation with visual acuity.

Objective: To summarize the original CT features of Pneumocystis Jirovecii pneumonia in patients with hematological diseases. Methods: A retrospective analysis was carried out in 46 patients with proven pneumocystis pneumonia (PJP) in the Hospital of Hematology, Chinese Academy of Medical Sciences between January 2014 and December 2021. All patients had multiple chests CT and related laboratory examinations, imaging typing were conducted based on the initial CT presentation, and the distinct imaging types were analyzed against the clinical data. Results: In the analysis, there were 46 patients with proven pathogenesis, 33 males, and 13 females, with a median age of 37.5 (2-65) years. The diagnosis was validated by bronchoalveolar lavage fluid (BALF) hexamine silver staining in 11 patients and clinically diagnosed in 35 cases. Of the 35 clinically diagnosed patients, 16 were diagnosed by alveolar lavage fluid macrogenomic sequencing (BALF-mNGS) and 19 by peripheral blood macrogenomic sequencing (PB-mNGS) . The initial chest CT presentation was categorized into 4 types, including ground glass (GGO) type in 25 cases (56.5%) , nodular type in 10 cases (21.7%) , fibrosis type in 4 cases (8.7%) , and mixed type in 5 cases (13.0%) . There was no substantial discrepancy in CT types among confirmed patients, BALF-mNGS diagnosed patients and PB-mNGS diagnosed patients (χ(2)=11.039, P=0.087) . The CT manifestations of confirmed patients and PB-mNGS diagnosed patients were primarily GGO type (67.6%, 73.7%) , while that of BALF-mNGS diagnosed patients were nodular type (37.5%) . Of the 46 patients, 63.0% (29/46) had lymphocytopenia in the peripheral blood, 25.6% (10/39) with positive serum G test, and 77.1% (27/35) with elevated serum lactate dehydrogenase (LDH) . There were no great discrepancies in the rates of lymphopenia in peripheral blood, positive G-test, and increased LDH among different CT types (all P>0.05) . Conclusion: The initial chest CT findings of PJP in patients with hematological diseases were relatively prevalent with multiple GGO in both lungs. Nodular and fibrosis types were also the initial imaging findings for PJP.

According to the theory of acupuncture-moxibustion for the treatment of spirit, starting from the relationship between eye movement and spirit, the application of electrooculogram (EOG) signal acquisition and analysis technology for the clinical treatment of spirit by acupuncture-moxibustion is discussed. Based on the nonlinear dynamic characteristics of EOG signals, it is proposed to apply the approximate entropy algorithm to extract the EOG signal characteristics in autism spectrum disorder children under different behavior states, which could realize the preliminary exploration of the correlation between EOG signals and cognitive activities. This could provide a possibility to objectively reflect the patient' s current mental state, and could be used as a potential method to grasp spirit in clinical acupuncture- moxibustion treatment. Furthermore, considering the characteristics of acupoint stimulation on the body surface, the EOG signal acquisition and analysis technology could further be combined with biofeedback technology, and a new idea for clinical acupuncture-moxibustion to treat spirit guided by biofeedback of EOG is proposed.

Objective: To evaluate the efficacy and safety of HLA-haploidentical hematopoietic stem cell transplantation (allo-HSCT) for hepatitis-related aplastic anemia (HRAA) patients. Methods: Retrospective analysis was performed on hepatitis-associated aplastic anemia patients who received haplo-HSCT at our center between January 2012 and June 2022. October 30, 2022 was the final date of follow-up. Results: This study included 28 HRAA patients receiving allo-HSCT, including 18 males (64.3% ) and 10 females (35.7% ), with a median age of 25.5 (9-44) years. About 17 cases of severe aplastic anemia (SAA), 10 cases of very severe aplastic anemia (VSAA), and 1 case of transfusion-dependent aplastic anemia (TD-NSAA) were identified. Among 28 patients, 15 patients received haplo-HSCT, and 13 received MSD-HSCT. The 2-year overall survival (OS) rate, the 2-year failure-free survival (FFS) rate, the 2-year transplant-related mortality (TRM) rate, the 100-day grade Ⅱ-Ⅳ acute graft-versus-host disease (aGVHD) cumulative incidence rate, and the 2-year chronic graft-versus-host disease (cGVHD) cumulative incidence rate were 81.4%, 81.4% (95% CI 10.5% -20.6% ), 14.6% (95% CI 5.7% -34.3% ), 25.0% (95% CI 12.8% -45.4% ), and 4.2% (95% CI 0.6% -25.4% ), respectively. After transplantation, all patients had no significant liver function damage. Compared with the MSD-HSCT group, only the incidence of cytomegaloviremia was significantly higher in the haplo-HSCT group [60.0% (95% CI 35.2% -84.8% ) vs 7.7% (95% CI 0-22.2% ), P=0.004]. No statistically significant difference in the Epstein-Barr virus was found in the 2-year OS, 2-year FFS, 2-year TRM, and 100-day grade Ⅱ-Ⅳ aGVHD cumulative incidence rates and 2-year cGVHD cumulative incidence rate. Conclusion: Allo-HSCT is safe and effective for HRAA, and haplo-HSCT can be used as a safe and effective alternative for newly diagnosed HRAA patients who cannot obtain HLA-matched sibling donors.

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

Objective: To investigate the early effect and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with a 10-day decitabine-containing conditioning regimen in the treatment of acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) . Methods: From April 2021 to May 2022, 31 AML/MDS patients who received allo-HSCT with a 10-day decitabine-containing conditioning regimen were analyzed. Results: AML (n=10), MDS-AML (n=6), CMML-AML (n=1), and MDS (n=14) were identified in 31 patients, 16 males, and 15 females, with a median age of 41 (20-55) yr. Neutrophils and platelets were successfully implanted in 31 patients (100%), with a median implantation duration of 12 (9-30) and 14 (9-42) days, respectively. During the preconditioning period, 16 patients (51.6%) developed oral mucositis, with 15 cases of Ⅰ/Ⅱ grade (48.4%) and one case of Ⅲ grade (3.2%). After transplantation, 13 patients (41.9%) developed CMV viremia, six patients (19.4%) developed hemorrhagic cystitis, and four patients (12.9%) developed a local infection. The median time of acute graft versus host disease (aGVHD) following transplantation was 33 (12-111) days. The cumulative incidence of aGVHD and Ⅲ/Ⅳ grade aGVHD was 41.9% (95% CI 26.9%-61.0%) and 22.9% (95% CI 13.5%-47.5%), respectively. There was no severe cGVHD, and mild and moderate chronic GVHD (cGVHD) incidence was 23.5% (95% CI 12.1%-43.6%). As of November 30, 2022, only one of the 31 patients had relapsed, with a 1-yr cumulative relapse rate (CIR) of 3.2% (95% CI 0.5%-20.7%). There was only one relapse patient death and no non-relapse deaths. The 1-yr overall survival (OS) and disease-free survival (DFS) rates were 92.9% (95% CI 80.3%-100%) and 96.8% (95% CI 90.8%-100%), respectively. Conclusions: A 10-day decitabine-containing conditioning regimen for allo-HSCT reduced relapse and was safe and feasible in treating AML/MDS.

AIM: To explore the efficacy of preoperative intravitreal injection of conbercept combined with 25G+ pars plana vitrectomy(PPV)in the treatment of proliferative diabetic retinopathy(PDR).METHODS: The clinical data of 154 patients(176 eyes)with PDR admitted to our hospital from January 2019 to June 2021 were collected for retrospective analysis. According to the treatment methods, 80 patients(92 eyes)in combined treatment group were treated with preoperative intravitreal injection of conbercept combined with 25G+PPV, and 74 patients(84 eyes)in control group were given 25G+PPV only. The postoperative clinical efficacy and levels of adipokines [adiponectin(APN), retinol binding protein 4(RBP4)] before and after surgery were compared between both groups of patients.RESULTS: The combined treatment group showed better clinical efficacy than the control group at 1mo after surgery(P<0.05). Both groups had lower RBP4 levels at 3mo after surgery(P<0.05), with the combined treatment group showing a lower level than the control group(P<0.05). Serum APN levels significantly increased in both groups after surgery(P<0.05), with the combined treatment group having a higher level than the control group(P<0.05). The combined treatment group had lower incidence rates of retinal proliferation and postoperative complications after than the control group 3mo of follow-up(P<0.05).CONCLUSION: Preoperative intravitreal injection of conbercept combined with 25G+PPV is beneficial in improving the therapeutic effect of PDR and reducing the incidence rates of complications, which may be related to the regulations of the expressions of adipokines.

OBJECTIVE@#To observe the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) at Changqiang (GV 1) based on the modulation of electro-oculogram (EOG) signal for children with mental retardation, and explore the evaluation effect of the goal attainment scale (GAS) in children with mental retardation.@*METHODS@#Sixty children with mental retardation were randomly divided into a treatment group and a control group, with 30 cases in each one. The children in the control group were treated with conventional rehabilitation, 5 times a week. On the basis of the control group, TEAS at Changqiang (GV 1) under the modulation of EOG signal was adopted in the treatment group. When the similarity between the collected EOG signal and the template was within the range of EOG threshold, one electric stimulation was triggered at Changqiang (GV 1) for 20 s (continuous wave, 70-100 Hz in frequency, 0.1-0.2 ms in pulse width), lasting 30 min in each treatment, the intervention was given twice a week. One course of treatment was composed of 4 weeks, and 3 courses were required in total in the two groups. The infant-junior high school student's social living ability scale (S-M) and GAS were scored and compared before and after treatment in the two groups.@*RESULTS@#After treatment, the scores of self-living ability in the treatment group and communication ability in the control group were higher than those before treatment (P<0.01, P<0.05). The scores of collective activity and motor ability in the treatment group were higher than those in the control group (P<0.05). After treatment, GAS scores were higher than before treatment in both groups (P<0.001), and the score in the treatment group was higher than the control group (P<0.05).@*CONCLUSION@#TEAS under the modulation of EOG signal is conductive to improving the collective, motor and self-living abilities of the children with mental retardation and promoting children's individual goals. Compared with the standard score of S-M, the T value of GAS can better reflect the subtle progress of individual.

OBJECTIVE@#To analyze the characteristics and prognosis of acute leukemia(AL) with SET-NUP214 fusion gene.@*METHODS@#The clinical data of 17 patients over 14 years old newly diagnosed with SET-NUP214 positive AL admitted in Institute of Hematology and Blood Diseases Hospital from August 2017 to May 2021 were analyzed retrospectively.@*RESULTS@#Among the 17 SET-NUP214 positive patients, 13 cases were diagnosed as T-ALL (ETP 3 cases, Pro-T-ALL 6 cases, Pre-T-ALL 3 cases, Medullary-T-ALL 1 case), AML 3 cases (2 cases M5, 1 case M0) and ALAL 1 case. Thirteen patients presented extramedullary infiltration at initial diagnosis. All 17 patients received treatment, and a total of 16 cases achieved complete remission (CR), including 12 cases in patients with T-ALL. The total median OS and RFS time were 23 (3-50) months and 21 (0-48) months, respectively. Eleven patients received allogeneic hematopoietic stem cell transplantation(allo-HSCT), with median OS time of 37.5 (5-50) months and median RFS time of 29.5 (5-48) months. The median OS time of 6 patients in chemotherapy-only group was 10.5 (3-41) months, and median RFS time of 6.5 (3-39) months. The OS and RFS of patients with transplantation group were better than those of chemotherapy-only group (P=0.038). Among the 4 patients who relapsed or refractory after allo-HSCT, the SET-NUP214 fusion gene did not turn negative before transplantation. While, in the group of 7 patients who have not relapsed after allo-HSCT till now, the SET-NUP214 fusion gene expression of 5 patients turned negative before transplantation and other 2 of them were still positive.@*CONCLUSION@#The fusion site of SET-NUP214 fusion gene is relatively fixed in AL patients, often accompanied by extramedullary infiltration. The chemotherapy effect of this disease is poor, and allo-HSCT may improve its prognosis.

Objective:To compare the early efficacy of proximal femoral bionic nail (PFBN) and proximal femoral nail anti-rotation (PFNA) in the treatment of intertrochanteric fracture in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 45 elderly patients with intertrochanteric fracture treated at First Affiliated Hospital of Henan Polytechnic University from March 2020 to December 2021, including 13 males and 32 females; aged 70-96 years [(78.6±7.3)years]. According to the AO classification, there were 10 patients with type 31-A1, 16 type 31-A2 and 19 type 31-A3. There were 20 patients treated with PFBN (PFBN group) and 25 with PFNA (PFNA group). The operation time, intraoperaive blood loss, bone healing time, and time to full weight-bearing were compared between the two groups. The tip-apex distance, distance from tail of lag screw to lateral side of intramedllary nail, proximal femoral length and femur neck-shaft angle were compared between the two groups at day 1 postoperatively and at the last follow-up, and their amount of changes between the two time points were also measured. Harris hip score was evaluated at 3, 6 months postoperatively and at the last follow-up. Complications were observed as well.Results:All patients were followed up for 6-21 months [(14.7±3.6)months]. There were no significant differences in operation time, intraoperative blood loss and bone healing time between the two groups (all P>0.05). The time to full weight-bearing was significantly earlier in PFBN group [(7.9±1.2)weeks] than that in PFNA group [(9.1±0.9)weeks] ( P<0.05). At day 1 postoperatively and at last follow-up, the tip-apex distance was (23.4±1.7)mm and (23.3±1.6)mm in PFBN group ( P>0.05), and was (24.5±2.1)mm and (24.3±2.3)mm in PFNA group ( P>0.05); the distance from tail of lag screw to lateral side of intramedllary nail was (8.1±1.1)mm and (11.8±0.9)mm in PFBN group ( P<0.01), and was (7.7±1.0)mm and (12.6±1.6)mm in PFNA group ( P<0.01); the proximal femoral length was (91.3±1.6)mm and (88.5±2.6)mm in PFBN group ( P<0.01), and was (91.4±2.0)mm and (87.6±2.0)mm in PFNA group ( P<0.01); the femur neck-shaft angle was (127.2±2.9)°and (125.7±3.0)° in PFBN group ( P>0.05), and was (128.5±3.0)° and (127.2±3.2)° in PFNA group ( P>0.05). There were no significant differences in the above indicators between the two groups at day 1 postoperatively and at the last follow-up (all P>0.05). The amount of changes in the tip-apex distance and femur neck-shaft angle were (-0.2±0.1)mm and (-1.6±0.7)° in PFBN group, similar with (-0.2±0.2)mm and (-1.5±1.0)° in PFNA group (all P>0.05). However, the amount of changes in the distance from tail of lag screw to lateral side of intramedllary nail and proximal femoral length were (3.6±1.4)mm and (2.7±1.2)mm in PFBN group, significantly lower than (5.2±1.1)mm and (4.0±1.1)mm in PFNA group (all P<0.01). There were no significant differences in Harris hip score between the two groups at 3, 6 months postoperatively or at the last follow-up (all P>0.05). PFBN group had 1 patient with fracture displacement, 2 with compression screw backup and 2 with thigh pain. PFNA group had 1 patient with fracture displacement and 4 with thigh pain. Conclusion:For elderly patients with intertrochanteric fracture, PFBN provides not only earlier full weight-bearing, but also stronger stability of fracture fixation than PFNA.

Objective: To compare the efficacy of two induction regimens, namely, idarubicin combined with cytarabine (IA) versus the combination of homoharringtonine, daunorubicin, and cytarabine (HAD) , in adult patients with newly diagnosed de novo acute myeloid leukemia (AML) . Methods: From May 2014 to November 2019, 199 patients diagnosed with AML receiving either the IA or HAD regimens were assessed for overall survival (OS) , relapse-free survival (RFS) , as well as the CR rate and the MRD negative rate after induction therapy. The differences in prognosis between the two induction therapy groups was assessed according to factors, including age, white blood cell (WBC) count, NPM1 mutation, FLT3-ITD mutation, 2017 ELN risk stratification, CR(1) transplantation, and the use of high-dose cytarabine during consolidation therapy, etc. Results: Among the 199 patients, there were 104 males and 95 females, with a median age of 37 (15-61) years. Ninety patients received the IA regimen, and 109 received the HAD regimen. Comparing the efficacy of the IA and HAD regimens, the CR rates after the first induction therapy were 71.1% and 63.3%, respectively (P=0.245) , and the MRD negative rates after the first induction therapy were 53.3% and 48.6%, respectively (P=0.509) . One patient in the IA group and two in the HAD group died within 60 days after induction. The two-year OS was 61.5% and 70.6%, respectively (P=0.835) , and the two-year RFS was 51.6% and 57.8%, respectively (P=0.291) . There were no statistically significant differences between the two groups. Multivariate analysis showed that the ELN risk stratification was an independent risk factor in both induction groups; CR(1) HSCT was an independent prognostic factor for OS and RFS in the IA patients and for RFS in the HAD patients but not for OS in the HAD patients. Age, WBC level, NPM1 mutation, and FLT3-ITD mutation had no independent prognostic significance. Conclusion: The IA and HAD regimens were both effective induction regimens for AML patients.

Objective: To evaluate the efficacy and toxicity profiles of idarubicin, cytarabine, and cyclophosphamide (IAC) in relapse/refractory acute myeloid leukemia (AML) . Methods: This study was a prospective, randomized controlled clinical trial with the registration number NCT02937662. The patients were randomly divided into two groups. The experimental group was treated with an IAC regimen, and the regimen of the control group was selected by doctors according to medication experience. After salvage chemotherapy, allogeneic hematopoietic stem cell transplantation (allo-HSCT) was conducted as far as possible according to the situation of the patients. We aimed to observe the efficacy, safety, and toxicity of the IAC regimen in relapse/refractory AML and to explore which is the better regimen. Results: Forty-two patients were enrolled in the clinical trial, with a median age of 36 years (IAC group, 22 cases and control groups, 20 cases) . ①The objective response rate was 71.4% in the IAC group and 40.0% in the control group (P=0.062) ; the complete remission (CR) rate was 66.7% in the IAC group and 40.0% in the control group (P=0.121) . The median follow-up time of surviving patients was 10.5 (range:1.7-32.8) months; the median overall survival (OS) was 14.1 (range: 0.6-49.1) months in the IAC group and 9.9 (range: 2.0-53.8) months in the control group (P=0.305) . The 1-year OS was 54.5% (95%CI 33.7%-75.3%) in the IAC group and 48.2% (95%CI 25.9%-70.5%) in the control group (P=0.305) , with no significant difference between these two regimens. ②The main hematologic adverse events (AEs) were anemia, thrombocytopenia, and neutropenia. The incidence of grade 3-4 hematologic AEs in the two groups was 100% (22/22) in the IAC group and 95% (19/20) in the control group. The median time of neutropenia after chemotherapy in the IAC group and control group was 20 (IQR: 8-30) and 14 (IQR: 5-50) days, respectively (P=0.023) . ③The CR rate of the early relapse (relapse within 12 months) group was 46.7% and that of the late relapse (relapse after 12 months) group was 72.7% (P=0.17) . The median OS time of early recurrence was 9.9 (range:1.7-53.8) months, and that of late recurrence patients was 19.3 (range: 0.6-40.8) months (P=0.420) , with no significant differences between the two groups. The 1-year OS rates were 45.3% (95%CI 27.2%-63.3%) and 66.7% (95%CI 40.0%-93.4%) , respectively (P=0.420) . Survival analysis showed that the 1-year OS rates of the hematopoietic stem cell transplantation group and non-hematopoietic stem cell transplantation group were 87.5% (95%CI 71.2%-100%) and 6.3% (95%CI 5.7%-18.3%) , respectively. The OS rate of the hematopoietic stem cell transplantation group was significantly higher than that of the non-hematopoietic stem cell transplantation group (P<0.001) . Conclusion: The IAC regimen is a well-tolerated and effective regimen in relapsed/refractory AML; this regimen had similar efficacy and safety with the regimen selected according to the doctor's experience for treating relapsed/refractory AML. For relapsed/refractory patients with AML, allogeneic hematopoietic stem cell transplantation should be attempted as soon as possible to achieve long-term survival.

By consulting ancient herbal medicines, medical and prescription books, combined with modern documents, the textual research of Morindae Officinalis Radix has been conducted to verify the name, origin, changes in production areas, quality evaluation, harvesting, and processing methods, so as to provide reference and basis for the development and utilization of the famous classical formulas. After textual research, the production areas of Morindae Officinalis Radix has experienced great changes from north to south in history. The original plants involve 11 families, 14 genera and 21 species, and the mainstream varieties in ancient times were Damnacanthus officinarum and D. indicus, and the basis of Morindae Officinalis Radix in modern times has changed into the dry roots of Morinda officinalis produced in Guangdong province and other places. The medicinal parts of Morindae Officinalis Radix in ancient and modern times are all roots, and the quality is better if it has many beads, thick flesh, and purple color. Ancient medical books recorded that it was usually harvested in February and August, dried in the shade, and used to remove the wood core. And the modern harvesting and processing method is to dig throughout the year, first remove the fibrous roots, dry in the sun until 60%-70% dry, gently beat flatten and dry in the sun. The processing methods of the past dynasties are mainly salt-, vinegar-, wine-processed, etc. Based on the systematic research of Morindae Officinalis Radix, from the perspective of clinical experience and safety and effectiveness, it is recommended that the famous classical formulas should be developed from the mainstream variety since modern times, namely Morindae Officinalis Radix.

【Objective】 To understand the effect of long-term high-frequency platelet donation on the health, safety and platelet quality of blood donors. 【Methods】 From August 2020 to July 2022, blood donors who donated platelets for single collection in the station were selected as two groups: those who donated for 20-29 times and those who donated for 30-44 times. Such 14 test indexes as red blood cell count (RBC), hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), platelet count (Plt), white blood cell count (WBC), large platelet ratio (P-LCR), lymphocyte (LYM) , neutrophil (NE), mean hemoglobin content (MCH), mean hemoglobin concentration (MCHC), platelet specific volume (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) were grouped and statistically analyzed for 5 times in each group. In addition, blood donors who have donated platelets more than 100 times in the station were chosen; the changes of their 5 parameters as RBC, Hb, Hct, PLT and WBC, as well as the correlation with the total number of platelet donations were analyzed through statistical analysis of the first 100 donations(10 donations/group). 【Results】 During 2 years, the hematological parameters were similar between 20-29 donation group(n=30) and 30-44 donation group(n=11) (P>0.05). For donors with donations≥100 occasions, RBC, Hb, Hct and WBC were negatively correlated with the number of blood donations, while Plt was positively correlated. There were significant differences in Hb, Hct, WBC and Plt among groups (P<0.05). Hb, Hct and WBC showed a downward trend, while Plt showed an upward trend. 【Conclusion】 With the increase of blood donations and units of blood donated, some changes in hematological parameters are observed among long-term high-frequency platelet donors. Monitoring and health education should be strengthened to ensure the safety and quality of blood donors.

Twenty batches of Aurantii Fructus Immaturus(AFI) were collected, with their peel and pulp taken as research objects. Ultra-high performance liquid chromatography(UPLC) fingerprints of peel and pulp of AFI were established with 17 common peaks in peel and 10 in pulp. Six kinds of flavonoids were identified, i.e., narirutin, naringin, rhoifolin, hesperidin, neohesperidin and nobiletin. The Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine was employed for similarity analysis, which showed that the chromatographic peaks of peel and pulp were basically similar to their respective reference fingerprints, with all similarities greater than 0.90. The similarity between peel and pulp of the same batch of AFI ranged from 0.850 to 0.983. Cluster analysis(CA), principal component analysis(PCA), and orthogonal partial least squares discriminant analysis(OPLS-DA) were conducted on the common peaks of peel and pulp of AFI with SPSS 17.0 and SIMCA 14.1. Combined with the reference fingerprints, these analyses revealed 12 differential components regarding peel and pulp. Further, the content of the 6 flavonoids and synephrine was determined. The proposed method integrating UPLC fingerprint and multicomponent quantitative analysis is applicable to the quality evaluation of AFI. The results provide a certain basis for the scientific connotation about the appearance characteristic of AFI.
