Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ2=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

Dichloroacetic acid and rapamycin synergistically inhibit tumor progression / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Mammalian target of rapamycin (mTOR) controls cellular anabolism, and mTOR signaling is hyperactive in most cancer cells. As a result, inhibition of mTOR signaling benefits cancer patients. Rapamycin is a US Food and Drug Administration (FDA)-approved drug, a specific mTOR complex 1 (mTORC1) inhibitor, for the treatment of several different types of cancer. However, rapamycin is reported to inhibit cancer growth rather than induce apoptosis. Pyruvate dehydrogenase complex (PDHc) is the gatekeeper for mitochondrial pyruvate oxidation. PDHc inactivation has been observed in a number of cancer cells, and this alteration protects cancer cells from senescence and nicotinamide adenine dinucleotide (NAD+‍) exhaustion. In this paper, we describe our finding that rapamycin treatment promotes pyruvate dehydrogenase E1 subunit alpha 1 (PDHA1) phosphorylation and leads to PDHc inactivation dependent on mTOR signaling inhibition in cells. This inactivation reduces the sensitivity of cancer cells' response to rapamycin. As a result, rebooting PDHc activity with dichloroacetic acid (DCA), a pyruvate dehydrogenase kinase (PDK) inhibitor, promotes cancer cells' susceptibility to rapamycin treatment in vitro and in vivo.

Immobilization of Lactobacillus bulgaricus with gellan gum and its application in continuous fermentation of D-lactic acid from corn straw / 生物工程学报

Biorefinery of chemicals from straw is an effective approach to alleviate the environmental pollution caused by straw burning. In this paper, we prepared gellan gum immobilized Lactobacillus bulgaricus T15 gel beads (LA-GAGR-T15 gel beads), characterized their properties, and established a continuous cell recycle fermentation process for D-lactate (D-LA) production using the LA-GAGR-T15 gel beads. The fracture stress of LA-GAGR-T15 gel beads was (91.68±0.11) kPa, which was 125.12% higher than that of the calcium alginate immobilized T15 gel beads (calcium alginate-T15 gel beads). This indicated that the strength of LA-GAGR-T15 gel beads was stronger, and the strain was less likely to leak out. The average D-LA production was (72.90±2.79) g/L after fermentation for ten recycles (720 h) using LA-GAGR-T15 gel beads as the starting strain and glucose as the substrate, which was 33.85% higher than that of calcium alginate-T15 gel beads and 37.70% higher than that of free T15. Subsequently, glucose was replaced by enzymatically hydrolyzed corn straw and fermented for ten recycles (240 h) using LA-GAGR-T15 gel beads. The yield of D-LA reached (1.74±0.79) g/(L·h), which was much higher than that of using free bacteria. The wear rate of gel beads was less than 5% after ten recycles, which indicated that LA-GAGR is a good carrier for cell immobilization and can be widely used in industrial fermentation. This study provides basic data for the industrial production of D-LA using cell-recycled fermentation, and provides a new way for the biorefinery of D-LA from corn straw.

Efficacy and safety of secondary allogeneic hematopoietic stem cell transplantation in 70 patients with recurrent hematologic malignancies after transplantation / 中华血液学杂志

Objectives: To investigate the role of donor change in the second hematopoietic stem cell transplantation (HSCT2) for hematological relapse of malignant hematology after the first transplantation (HSCT1) . Methods: We retrospectively analyzed patients with relapsed hematological malignancies who received HSCT2 at our single center between Mar 1998 and Dec 2020. A total of 70 patients were enrolled[49 males and 21 females; median age, 31.5 (3-61) yr]. Results: Forty-nine male and 21 female patients were enrolled in the trial. At the time of HSCT2, the median age was 31.5 (3-61) years old. Thirty-one patients were diagnosed with acute myeloid leukemia, 23 patients with ALL, and 16 patients with MDS or other malignant hematology disease. Thirty patients had HSCT2 with donor change, and 40 patients underwent HSCT2 without donor change. The median relapse time after HSCT1 was 245.5 (26-2 905) days. After HSCT2, 70 patients had neutrophil engraftment, and 62 (88.6%) had platelet engraftment. The cumulative incidence of platelet engraftment was (93.1±4.7) % in patients with donor change and (86.0±5.7) % in patients without donor change (P=0.636). The cumulative incidence of CMV infection in patients with and without donor change was (64.0±10.3) % and (37.0±7.8) % (P=0.053), respectively. The cumulative incidence of grade Ⅱ-Ⅳ acute graft versus host disease was (19.4±7.9) % vs (31.3±7.5) %, respectively (P=0.227). The cumulative incidence of TRM 100-day post HSCT2 was (9.2±5.1) % vs (6.7±4.6) % (P=0.648), and the cumulative incidence of chronic graft versus host disease at 1-yr post-HSCT2 was (36.7±11.4) % versus (65.6±9.1) % (P=0.031). With a median follow-up of 767 (271-4 936) days, 38 patients had complete remission (CR), and three patients had persistent disease. The CR rate was 92.7%. The cumulative incidences of overall survival (OS) and disease-free survival (DFS) 2 yr after HSCT2 were 25.8% and 23.7%, respectively. The cumulative incidence of relapse, OS, and DFS was (52.6±11.6) % vs (62.4±11.3) % (P=0.423), (28.3±8.6) % vs (23.8±7.5) % (P=0.643), and (28.3±8.6) % vs (22.3±7.7) % (P=0.787), respectively, in patients with changed donor compared with patients with the original donor. Relapses within 6 months post-HSCT1 and with persistent disease before HSCT2 were risk factors for OS, DFS, and CIR. Disease status before HSCT2 and early relapse (within 6 months post-HSCT1) was an independent risk factor for OS, DFS, and CIR post-HSCT2. Conclusion: Our findings indicate that changing donors did not affect the clinical outcome of HSCT2.

Magnetic compression anastomosis for esophagoenterostomy after total gastrectomy in rats / 西安交通大学学报(医学版)

【Objective】 Digestive tract reconstruction after total gastrectomy is complicated and causes many complications. This study aimed to investigate the feasibility, safety and effectiveness of magnetic compression anastomosis (MCA) for sutureless reconstruction after total gastrectomy in rats. 【Methods】 Twenty-four rats were randomly apportioned to two groups. Reconstruction was performed with MCA in the experimental group or hand-sewn in the control group, and the construction time was recorded. The animals were followed up for 30 days. The survival rate and complications were monitored. At each time point, the rats were euthanized to study the gross/histological morphology and mechanical strength of the anastomoses. 【Results】 The reconstruction time was (12.9±2.7)min in the experimental group and (23.8±4.1)min in the control group (P=0.036). In the experimental group, there was no anastomotic complication. Four control rats developed anastomotic leakage or hemorrhage, and all died within 4 postoperative days. Compared with the control group, burst pressure in the experimental group was similar. Both groups’ anastomoses had smooth gross appearance and histologically good alignment of tissue layers. 【Conclusion】 MCA is a safe and effective choice for reconstruction after total gastrectomy, with better postoperative outcomes than hand-sewn.

Prediction of the Duration to Next Admission for an Acute Affective Episode in Patients with Bipolar I Disorder

Objective@#Predicting disease relapse and early intervention could reduce symptom severity. We attempted to identify potential indicators that predict the duration to next admission for an acute affective episode in patients with bipolar I disorder. @*Methods@#We mathematically defined the duration to next psychiatric admission and performed single-variate regressions using historical data of 101 patients with bipolar I disorder to screen for potential variables for further multivariate regressions. @*Results@#Age of onset, total psychiatric admissions, length of lithium use, and carbamazepine use during the psychiatric hospitalization contributed to the next psychiatric admission duration positively. The all-in-one found that hyperlipidemia during the psychiatric hospitalization demonstrated a negative contribution to the duration to next psychiatric admission; the last duration to psychiatric admission, lithium and carbamazepine uses during the psychiatric hospitalization, and heart rate on the discharge day positively contributed to the duration to next admission. @*Conclusion@#We identified essential variables that may predict the duration of bipolar I patients’ next psychiatric admission. The correlation of a faster heartbeat and a normal lipid profile in delaying the next onset highlights the importance of managing these parameters when treating bipolar I disorder.

Syndrome Differentiation-based Treatment of Diarrhea-predominant Irritable Bowel Syndrome with Chinese Medicine via 5-HT Signaling Pathway： A Review / 中国实验方剂学杂志

Diarrhea-predominant irritable bowel syndrome （IBS-D） is a chronic functional bowel disorder characterized by abdominal pain and diarrhea， with visceral hypersensitivity and abnormal gastrointestinal dynamics as the pathophysiological basis. The brain-gut interaction plays a role in pain-related functional gastrointestinal disorders， especially IBS-D. 5-Hydroxytryptamine （5-HT）， as an important brain-gut peptide regulating gastrointestinal function， affects brain activity， gastrointestinal motility， pain perception， mucosal inflammation， and immune response through brain-gut interaction and is associated with the occurrence and development of IBS-D. In recent years， traditional Chinese medicine （TCM） has shown great potential to mitigate gastrointestinal symptoms and improve the quality of life with its holistic view and treatment based on syndrome differentiation. Studies have shown that TCM treats IBS-D by regulating the 5-HT signaling pathway. With a focus on syndrome differentiation in TCM， this paper systematically describes the efficacy and mechanism of TCM in treating different TCM syndromes of IBS-D via the 5-HT signaling pathway， aiming to provide a scientific basis for TCM treatment of this disease.

Accuracy of optical surface-guided hypo-fractionated radiotherapy for intracranial metastasis with open face mask immobilization / 中华放射肿瘤学杂志

Objective:To investigate the feasibility of surface-guided hypo-fractionated radiotherapy for intracranial metastasis with open face mask immobilization.Methods:Nineteen patients treated with hypo- fractionated radiotherapy for intracranial metastasis in our hospital were included. Before the start of treatment, each patient underwent simulation with open face mask immobilization. During the treatment, cone-beam CT(CBCT)images were collected for verification each time. Laser-guided positioning was used for the first time in the treatment, and surface images were captured after six-dimensional position correction as the reference images for subsequent treatment. Subsequent treatment was randomly divided into laser-guided positioning group(LG, 85/F)and optical surface-guided positioning group(SG, 101/F). The six-dimensional error data of patients with two positioning methods were compared and expressed as mean ± standard deviation. Meanwhile, the correlation and consistency between the optical surface error data and the gold standard CBCT error data were compared in the laser-guided fraction. GraphPad Prism 6.0 software was used for data processing and mapping, and SPSS 21.software was used for mean analysis and normality test. Pearson correlation analysis was used to analyze the correlation, and Bland-Altman plot analysis was used to test the coincidence between two methods.Results:Compared with the laser-guided positioning, the 3D error of optical surface-guided positioning was reduced from(0.35±0.16)cm to(0.14±0.07)cm. The Pearson coefficient of correlation along all three directions was less than 0.01,R 2 was 0.91,0.70 and 0.78 on Lat, Lng and Vrt, and R 2 was 0.75,0.85 and 0.77 on Pitch, Roll and Rtn(all P<0.01), respectively. The measurement results of two methods were positively correlated. The Bland-Altman plot analysis showed that the 95% limits of agreement were within preset 3 mm tolerance([-0.29 cm, 0.19 cm], [-0.25 cm, 0.25 cm], [-0.27 cm, 0.19 cm]), and the 95% limits of agreement were within preset 3° tolerance(Pitch[-1.76°,1.76°], Roll[-1.54°,1.60°], ROT[-2.18°,1.69°]), indicating agreement between two methods. Conclusions:The optical surface-guided positioning can reduce the setup errors in the hypo-fractionated radiotherapy for intracranial metastasis with open face mask immobilization. The optical surface error and CBCT error have good correlation and agreement.

Early life adversity and depression / 中华行为医学与脑科学杂志

The onset of depression is related to many factors such as biological, psychological and social environment, and more and more studies have shown that early life adversity is a risk factor for depression. Patients with depression who have early life adversity have different clinical characteristics, such as greater cognitive impairment and higher risk of suicide, which may be related to changes in cognitive patterns. In addition, early life adversity can cause endocrine, immune and nervous system specific changes in depressed patients. This article reviews the relationship and mechanism between various types of early life adverse and depression, explores the onset of depression and provides theory evidence for early intervention.

Prevalence and Risk Factors of Postdialysis Fatigue in Patients Under Maintenance Hemodialysis: A Systematic Review and Meta-Analysis

Purpose@#Despite the high prevalence of postdialysis fatigue (PDF) in maintenance hemodialysis patients, no meta-analysis on the prevalence and risk factors of PDF has yet been published. This study aimed to identify the prevalence of PDF and explore its related factors. @*Methods@#PubMed, Embase, CENTRAL, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the four Chinese databases (National Knowledge Infrastructure [CNKI], Chinese Biomedical Literature database [SinoMed], Wanfang Digital Periodicals [WANFANG], and Chinese Science and Technology Periodicals [VIP] database) were searched from inception up to July 2022. This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The articles were independently searched by two reviewers, and the relevant data were extracted. The Agency for Healthcare Research and Quality was used to assess the quality of the included studies. @*Results@#Thirteen articles with 2,118 participants were included. The pooled prevalence was 60.0%. The meta-analysis results revealed that the ultrafiltration volume, mean arterial pressure after dialysis, and good sleep quality were potentially associated with PDF, whereas only good sleep quality (odds ratio 0.24, 95% confidence interval 0.19e0.30) was significantly associated with PDF. @*Conclusion@#PDF is common in maintenance hemodialysis patients, which is related to the ultrafiltration volume, sleep quality, and mean arterial pressure after dialysis. However, the mechanism underlying the risk factors and PDF remains unknown. Further research is warranted to investigate the risk factors, intervention, treatment, and mechanism in maintenance hemodialysis patients.

Impact of status determined by comprehensive geriatric assessment on setup error during rectal cancer radiotherapy for elderly patients / 中华放射医学与防护杂志

Objective:To explore the impacts of comprehensive geriatric assessment (CGA) on setup errors during the radiotherapy of elderly patients with rectal cancer.Methods:A total of 45 patients over 70 years of age and receiving radiotherapy were enrolled in the study. A comprehensive geriatric assessment was conducted before the radiotherapy. The enrolled patients had a median age of 77 years, including 28 male and 17 female cases. Meanwhile, 31 patients were determined to be in a good CGA status and 14 were determined to be in a poor CGA status, and 35 patients received radiotherapy in the prone position and 10 in the supine position. Cone beam CT (CBCT) was used for setup correction during radiotherapy. CBCT was performed daily in the first week and once a week from the second week. By fusing and aligning the CBCT images with simulation CT images according to the lumbar vertebra, setup errors in the left-right ( x axis), cranio-caudal ( y axis), and anterior-posterior ( z axis) directions were obtained. A total of 338 CBCT images were obtained. A generalized linear model was used to evaluate the effects of multiple factors on the setup errors. Results:During the radiotherapy, setup errors of all patients were (0.24±0.19) cm in the left-right direction, (0.33±0.25) cm in the cranio-caudal direction, and (0.19±0.15) cm in the anterior-posterior direction. The setup error in the cranio-caudal direction was more than that in the left-right direction and that in the anterior-posterior direction ( Z=-4.86, -7.72, P< 0.001). The setup error in the left-right direction was greater than that in the anterior-posterior direction ( Z=-2.79, P=0.005). The mean setup errors of the good and poor status groups in the left-right direction were (0.21 ± 0.17) and (0.30 ± 0.22) cm, respectively ( Z=2.16, P=0.031). There was no statistically significant difference in the setup errors between cranio-caudal direction and anterior-posterior direction ( P>0.05). The setup errors in the anterior-posterior direction were (0.17 ± 0.13) and (0.27 ± 0.19) cm, respectively for the prone and supine positions during the radiotherapy ( Z=2.85, P=0.004). There was no statistically significant difference in the setup errors between the left-right direction and the cranio-caudal direction ( P>0.05). Conclusion:The status of CGA elderly patients with rectal cancer affects the setup error in the left-right direction. It may be necessary to clinically adjust the PTV margin.

The levels of prostaglandin E2 （PGE2）， cyclooxygenase-2 （COX-2）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and other inflammatory factors were detected before and after treatment. The pain medication usage and recurrence were recorded. ResultThe scores of dysmenorrhea， symptoms of pelvic pain symptoms （non-menstrual pelvic pain， dyspareunia， anal falling pain， and defecation pain， etc.）， and signs of pelvic pain （pelvic tenderness and sacral ligament tender nodules） in the observation group were lower than those in the control group （P<0.01）. The disappearance rates of dysmenorrhea， pelvic tenderness， and sacral ligament tender nodules were 67.35% （33/49）， 73.33% （33/45）， and 77.27% （34/44） in the observation group， which were all higher than 45.83% （22/48）， 48.84% （21/43）， and 52.27% （23/44） in the control group. The difference was statistically significant （χ2=4.571， χ2=5.565， χ2=6.026， P<0.05）. The scores of EHP-5 and syndrome of cold congeal and blood stasis in the observation group were lower than those in the control group （P<0.01）. The levels of VEGF， MMP-9， IGF-1， NGF， SP， CGRP， and BDNF in the observation group were lower than those in the control group （P<0.01）， while the level of sFlt-1 was higher than that in the control group （P<0.01）. The levels of PGE2， COX-2， TNF-α， and IL-6 in the observation group were lower than those in the control group （P<0.01）. The total effective rate of the observation group was 92.45% （49/53）， which was higher than 76.00% （38/50） of the control group （χ2=5.307， P<0.05）. After 6 months of follow-up， the recurrence rate in the observation group was 30.61% （15/49）， which was lower than 52.63% （20/38） in the control group （χ2=4.315， P<0.05）. The average of taking ibuprofen sustained-release capsules in the control group was higher than that in the observation group per menstrual period （P<0.01）. ConclusionModified Shaofu Zhuyutang treated pelvic pain of EMT with syndrome of cold congeal and blood stasis by regulating the mechanism of neural angiogenesis， reducing pain， and promoting the disappearance of related pains， thus improving the quality of life. Shaofu Zhuyutang has a better clinical effect than Aifu Nuangong pills and has a low recurrence rate.

The column temperature was set at 20 ℃. The detection wavelength was set at 450 nm，and sample size was 20 μL. Using zeaxanthin as control，the relative correction factors （RCFs）of β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate were calculated ， and then the content of each component was calculated according to RCFs and compared with the results of external standard method（ESM）. RESULTS The linear range of zeaxanthin ，β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate were 0.119 4-2.983 8，0.121 7-1.521 6，0.285 9-5.718 8，8.460 5-211.513 3 μg/mL（all R2＞0.999）. RSDs of precision ，repeatability and stability（16 h）tests were all less than 4％. The average recoveries were 103.34％，107.37％，105.64％，96.16％（RSD＜5％，n＝ 9）. The average RCFs of β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate were 1.109，1.390，1.158. The relative errors of the content determination results by quantitative analysis of multi-components by singer marker （QAMS）and ESM were within ±1％. CONCLUSIONS The established HPLC-QAMS method is accurate and stable ，which can be used for the content determination and quality control of 4 carotenoids in L. barbarum .

A preliminary study on the relationship between in vivo metal implants and acquired palmoplantar keratodermas / 中华皮肤科杂志

Objective:To investigate clinical characteristics of acquired palmoplantar keratodermas (PPK) and the effect of metal implants (MIs) on plasma cytokines in patients with PPK.Methods:An observational study was conducted. Patients with acquired PPK were collected from Department of Dermatology, General Hospital of Eastern Theater Command from June 2020 to December 2021, and health checkup examinees during the same period served as controls. The PPK area and severity index was evaluated according to the eczema area and severity index, metal allergens were detected by metal patch test (MPT) , and plasma levels of cytokines, including tumor necrosis factor (TNF) -α, interferon (IFN) -γ, interleukin (IL) -4, IL-13, IL-17A and IL-8, were detected by enzyme-linked immunosorbent assay. Non-normally distributed measurement data were expressed as median (quartile 1, quartile 3) , and analyzed by rank sum test; intergroup comparisons of enumeration data were performed by chi-square test.Results:A total of 81 PPK patients were collected, including 42 males and 39 females, and their average age was 48 years (range, 21 - 65 years) . In vivo MIs were found in 37 (45.7%) patients, including dental implants in 34, orthopedic implants in 2, and cardiac implants in 1. During the same period, 36 healthy subjects were included in the control group, and there was no significant difference in the age and gender composition between the two groups ( P > 0.05) . No significant difference was observed in the PPK area and severity index between the MI group (37 cases, 0.40 [0.27, 0.75] points) and non-MI group (44 cases, 0.38 [0.19, 0.70] points; Z = 1.21, P = 0.225) . Forty-six patients in the PPK patient group and 30 in the control group were subjected to MPT, and the positive rate of MPT was significantly higher in the patient group (14/46) than in the control group (2/30, χ2 = 6.17, P = 0.013) , and was significantly higher in the patients with in vivo MIs (10/25) than in the patients without (4/21, adjusted P < 0.017) . Plasma cytokines were detected in 36 cases in the patient group and 36 in the control group. The plasma levels of TNF-α and IFN-γ were significantly lower in the patient group (66.2 [58.7, 69.3] pg/ml, 645.0 [571.5, 681.1] pg/ml, respectively) than in the control group (71.5 [64.5, 73.9] pg/ml, 716.5 [620.4, 785.0] pg/ml, respectively; both P < 0.05) , but there was no significant difference in the levels of plasma IL-4, IL-13, IL-17A and IL-8 between the two groups (all P > 0.05) . Conclusions:Positive MPT reaction is more common in acquired PPK patients, especially in patients with in vivo MIs. There may be a correlation between metal and acquired PPK, and changes in plasma TNF-α and IFN-γ levels may be related to the onset of some acquired PPK.

Adrenocorticotrophic hormone stimulation in adrenal vein sampling / 中华内分泌代谢杂志

Objective:To explore the value of adrenocorticotrophic hormone (ACTH) stimulation in adrenal vein sampling (AVS) with its effect on the sampling success rate and lateralization determination.Methods:The clinical data of 54 patients with primary aldosteronism (PA) who underwent AVS in Nanjing Drum Tower Hospital from July 2018 to June 2020 were collected retrospectively. Blood samples from bilateral adrenal veins were collected simultaneously at baseline and after ACTH stimulation. The selectivity index (SI), lateralization index (LI), and relative aldosterone secretion index (RASI) were examined.Results:The concentration of serum cortisol level in left and right adrenal vein and peripheral vein increased significantly after ACTH stimulation ( P<0.001). SI of left adrenal vein increased from 18.00 (2.29, 20.29) to 34.76 (12.10, 46.86) , and the SI of right adrenal vein increased from 26.61(5.24, 31.85) to 28.40 (27.65, 56.05, P<0.001). The bilateral vein sampling success rate increased from 80%(43/54) to 93%(50/54). LI decreased from 2.85(1.78, 6.20) at baseline to 2.45(1.40, 6.10) after ACTH stimulation without significant difference( P>0.05). Eleven patients who identified unilateral secretion at baseline demonstrated bilateral after ACTH stimulation, and the RASI of these patients decreased from 0.50 (0.38, 1.25 ) to 0.37 (0.22, 0.84, P=0.019). Conclusion:ACTH stimulation significantly increased SI and the AVS success rate in patients with PA: ACTH stimulation decreased the relative aldosterone secretion in the dominant side of some patients with aldosterone producing adenoma, thus reduced the proportion of identified unilateral PA.

A retrospective comparative study of haplotype hematopoietic stem cell transplantation and human leukocyte antigen-matched sibling donor hematopoietic stem cell transplantation in the treatment of acute B-lymphocyte leukemia / 中华血液学杂志

Objective: To investigate whether haplotype hematopoietic stem cell transplantation (haplo-HSCT) is effective in the treatment of pre transplant minimal residual disease (Pre-MRD) positive acute B lymphoblastic leukemia (B-ALL) compared with HLA- matched sibling donor transplantation (MSDT) . Methods: A total of 998 patients with B-ALL in complete remission pre-HSCT who either received haplo-HSCT (n=788) or underwent MSDT (n=210) were retrospectively analyzed. The pre-transplantation leukemia burden was evaluated according to Pre-MRD determinedusing multiparameter flow cytometry (MFC) . Results: Of these patients, 997 (99.9% ) achieved sustained, full donor chimerism. The 100-day cumulative incidences of neutrophil engraftment, platelet engraftment, and grades Ⅱ-Ⅳ acute graft-versus-host disease (GVHD) were 99.9% (997/998) , 95.3% (951/998) , and 26.6% (95% CI 23.8% -29.4% ) , respectively. The 3-year cumulative incidence of total chronic GVHD was 49.1% (95% CI 45.7% -52.4% ) . The 3-year cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) of the 998 cases were 17.3% (95% CI 15.0% -19.7% ) and 13.8% (95% CI 11.6% -16.0% ) , respectively. The 3-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 69.1% (95% CI 66.1% -72.1% ) and 73.0% (95% CI 70.2% -75.8% ) , respectively. In the total patient group, cases with positive Pre-MRD (n=282) experienced significantly higher CIR than that of subjects with negative Pre-MRD [n=716, 31.6% (95% CI 25.8% -37.5% ) vs 14.3% (95% CI 11.4% -17.2% ) , P<0.001]. For patients in the positive Pre-MRD subgroup, cases treated with haplo-HSCT (n=219) had a lower 3-year CIR than that of cases who underwent MSDT [n=63, 27.2% (95% CI 21.0% -33.4% ) vs 47.0% (95% CI 33.8% -60.2% ) , P=0.002]. The total 998 cases were classified as five subgroups, including cases with negative Pre-MRD group (n=716) , cases with Pre-MRD<0.01% group (n=46) , cases with Pre-MRD 0.01% -<0.1% group (n=117) , cases with Pre-MRD 0.1% -<1% group (n=87) , and cases with Pre-MRD≥1% group (n=32) . For subjects in the Pre-MRD<0.01% group, haplo-HSCT (n=40) had a lower CIR than that of MSDT [n=6, 10.0% (95% CI 0.4% -19.6% ) vs 32.3% (95% CI 0% -69.9% ) , P=0.017]. For patients in the Pre-MRD 0.01% -<0.1% group, haplo-HSCT (n=81) also had a lower 3-year CIR than that of MSDT [n=36, 20.4% (95% CI 10.4% -30.4% ) vs 47.0% (95% CI 29.2% -64.8% ) , P=0.004]. In the other three subgroups, the 3-year CIR was comparable between patients who underwent haplo-HSCT and those received MSDT. A subgroup analysis of patients with Pre-MRD<0.1% (n=163) was performed, the results showed that cases received haplo-HSCT (n=121) experienced lower 3-year CIR [16.0% (95% CI 9.4% -22.7% ) vs 40.5% (95% CI 25.2% -55.8% ) , P<0.001], better 3-year LFS [78.2% (95% CI 70.6% -85.8% ) vs 47.6% (95% CI 32.2% -63.0% ) , P<0.001] and OS [80.5% (95% CI 73.1% -87.9% ) vs 54.6% (95% CI 39.2% -70.0% ) , P<0.001] than those of MSDT (n=42) , but comparable in 3-year NRM [5.8% (95% CI 1.6% -10.0% ) vs 11.9% (95% CI 2.0% -21.8% ) , P=0.188]. Multivariate analysis showed that haplo-HSCT was associated with lower CIR (HR=0.248, 95% CI 0.131-0.472, P<0.001) , and superior LFS (HR=0.275, 95% CI 0.157-0.483, P<0.001) and OS (HR=0.286, 95% CI 0.159-0.513, P<0.001) . Conclusion: Haplo HSCT has a survival advantage over MSDT in the treatment of B-ALL patients with pre MRD<0.1% .
