Predictive visual field outcomes after optic chiasm decompressive surgery by retinal vessels parameters using optical coherence tomography angiography.

AIM: To evaluate the predictive value of superficial retinal capillary plexus (SRCP) and radial peripapillary capillary (RPC) for visual field recovery after optic cross decompression and compare them with peripapillary nerve fiber layer (pRNFL) and ganglion cell complex (GCC). METHODS: This prospective longitudinal observational study included patients with chiasmal compression due to sellar region mass scheduled for decompressive surgery. Generalized estimating equations were used to compare retinal vessel density and retinal layer thickness pre- and post-operatively and with healthy controls. Logistic regression models were used to assess the relationship between preoperative GCC, pRNFL, SRCP, and RPC parameters and visual field recovery after surgery. RESULTS: The study included 43 eyes of 24 patients and 48 eyes of 24 healthy controls. Preoperative RPC and SRCP vessel density and pRNFL and GCC thickness were lower than healthy controls and higher than postoperative values. The best predictive GCC and pRNFL models were based on the superior GCC [area under the curve (AUC)=0.866] and the tempo-inferior pRNFL (AUC=0.824), and the best predictive SRCP and RPC models were based on the nasal SRCP (AUC=0.718) and tempo-inferior RPC (AUC=0.825). There was no statistical difference in the predictive value of the superior GCC, tempo-inferior pRNFL, and tempo-inferior RPC (all P>0.05). CONCLUSION: Compression of the optic chiasm by tumors in the saddle area can reduce retinal thickness and blood perfusion. This reduction persists despite the recovery of the visual field after decompression surgery. GCC, pRNFL, and RPC can be used as sensitive predictors of visual field recovery after decompression surgery.

[Clinical Characteristics and Prognosis of Patients with Primary Testicular Diffuse Large B-Cell Lymphoma].

OBJECTIVE: To analyze the clinical manifestations, therapeutic response and prognosis of patients with primary testicular diffuse large B-cell lymphoma (PT-DLBCL). METHODS: Thirty-eight patients with PT-DLBCL were enrolled, who hospitalized from January 2010 to April 2021, and their clinical characteristics, treatment regimen and efficacy were collected and analyzed retrospectively. RESULTS: The median age of the patients was 56 years old (ranged from 38 to 79 years). There were 4 cases (10.5%) with bilateral lesions, 13 cases (34.2%) with left lesions, and 21 cases (55.3%) right lesions. There were 2 cases(5.3%) with B symptoms, 6 cases (15.8%) of germinal center B-cell-like(GCB) subtype and 32 cases(84.2%) of non-GCB subtype. Efficacy was evaluated in 36 cases, including 10 cases with CHOP regimen, 21 cases with R-CHOP regimen (7 cases were treated with rituximab combined with high-dose methotrexate injection chemotherapy at intervals of R-CHOP regimen), and 5 cases with other regimens. In 36 patients, the efficacy evaluation of initial chemotherapy showed that the overall response rate (ORR) was 86.1%, 29 cases (80.6%) reached complete response (CR), and 2 cases (5.5%) reached partial response (PR). The R-CHOP group was superior to CHOP group in ORR (95.2% vs 60.0%, P=0.027) and CR (90.4% vs 50.0%, P=0.022). Of the 36 patients, 7 cases had central nervous system(CNS) recurrence and 4 cases had contralateral testicular recurrence. Compared with the CHOP group, the CNS recurrence rate in the R-CHOP group was significantly lower (4.8% vs 50.0%, P=0.007), and the testicular recurrence rate in the R-CHOP group was also lower than the CHOP group, but the difference was not statistically significant (4.8% vs 30.0%, P=0.087). The median follow-up time was 27(3-135) months, and the 5-year PFS and OS were 71% and 74%, respectively. Kaplan-Meier univariate analysis showed that the R-CHOP regimen significantly improved the patients' PFS (P=0.024) and OS (P=0.025) compared with the CHOP regimen. CONCLUSION: PT-DLBCL is mainly treated with comprehensive treatment. Compared with CHOP regimen, R-CHOP regimen can improve the CR rate and ORR, reduce CNS recurrence and contralateral testicular recurrence, and improve the patients' survival. Patients may benefit from high-dose methotrexate combined with rituximab interlaced with R-CHOP regimen.

Hyperthermia promotes degradation of the acute promyelocytic leukemia driver oncoprotein ZBTB16/RARα.

The acute promyelocytic leukemia (APL) driver ZBTB16/RARα is generated by the t(11;17) (q23;q21) chromosomal translocation, which is resistant to combined treatment of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) or conventional chemotherapy, resulting in extremely low survival rates. In the current study, we investigated the effects of hyperthermia on the oncogenic fusion ZBTB16/RARα protein to explore a potential therapeutic approach for this variant APL. We showed that Z/R fusion protein expressed in HeLa cells was resistant to ATO, ATRA, and conventional chemotherapeutic agents. However, mild hyperthermia (42 °C) rapidly destabilized the ZBTB16/RARα fusion protein expressed in HeLa, 293T, and OCI-AML3 cells, followed by robust ubiquitination and proteasomal degradation. In contrast, hyperthermia did not affect the normal (i.e., unfused) ZBTB16 and RARα proteins, suggesting a specific thermal sensitivity of the ZBTB16/RARα fusion protein. Importantly, we found that the destabilization of ZBTB16/RARα was the initial step for oncogenic fusion protein degradation by hyperthermia, which could be blocked by deletion of nuclear receptor corepressor (NCoR) binding sites or knockdown of NCoRs. Furthermore, SIAH2 was identified as the E3 ligase participating in hyperthermia-induced ubiquitination of ZBTB16/RARα. In short, these results demonstrate that hyperthermia could effectively destabilize and subsequently degrade the ZBTB16/RARα fusion protein in an NCoR-dependent manner, suggesting a thermal-based therapeutic strategy that may improve the outcome in refractory ZBTB16/RARα-driven APL patients in the clinic.

[Clinical Features of Diffuse Large B-Cell Lymphoma Transformed from Follicular Lymphoma].

OBJECTIVE: To analyze the clinical manifestations, pathological characteristics, therapeutic effect and prognosis of diffuse large B-cell lymphoma (DLBCL) transformed from follicular lymphoma (FL). METHODS: A total of 45 inpatients were eligible for criteria of histologic transformation from FL to DLBCL from January 2010 to January 2021, and their clinical characteristics, diagnosis, treatment and efficacy were collected and analyzed retrospectively. RESULTS: Among the 45 patients, transformation occurred at diagnosis in 27 cases, during " watch and wait " phase in 7 cases and after treatment of FL in 11 cases. The median age was 56 years old (ranged from 27 to 76 years), with 23 male and 22 female. The transformations were observed in 8 cases with low-grade and 37 cases with high-grade FL. Extranodal involvement was present in 26 cases, including bone marrow infiltration in 16 cases. There were 17 cases with anemia and 32 cases met the GELF criteria of high tumor burden. B symptoms were present in 12 cases. There were 38 cases with Ki-67≥50%. The germinal center B-cell-like (GCB) subtype of DLBCL was observed in 43 cases. Efficacy was evaluated in 45 cases. The OR, CR and PR rate were 80.0%, 60.0% and 20.0%, respectively. The OR,CR rate of patients received R-CHOP was higher than those of patients received other regimens (86.11% vs 55.55%, P=0.063; 66.67% vs 33.33%, P=0.126), but there was no significant statistical difference. The early transformation (at diagnosis) group showed the highest OR rate (85.18%) and CR rate (74.07%). The median follow-up time of all patients was 26 (4-120) months, and the median PFS (2-120 months) and median OS (5-120 months) had not yet reached. The 3-year PFS and OS were 55% and 70%, respectively. In univariate analysis, factors affecting PFS includ OR rate and POD24, and factors affecting OS includ IPI score, OR rate, POD24, B symptoms and anemia (P<0.05).Multivariant analysis indicated that OR rate and POD24 were the independent prognostic factors for PFS (P<0.05) and IPI score was an independent prognostic factor for OS (P<0.05). CONCLUSION: The OR and CR rates are higher in early transformation group of patients with DLBCL transformed from FL. Patients with anemia, B symptoms, POD24, and high-risk score have poor prognosis. IPI score is the independent prognosis factor for OS.

Oral arsenic and retinoic acid for high-risk acute promyelocytic leukemia.

Acute promyelocytic leukemia (APL) has become curable over 95% patients under a complete chemo-free treatment with all-trans retinoic acid (ATRA) and arsenic trioxide in low-risk patients. Minimizing chemotherapy has proven feasible in high-risk patients. We evaluated oral arsenic and ATRA without chemotherapy as an outpatient consolidation therapy and no maintenance for high-risk APL. We conducted a multicenter, single-arm, phase 2 study with consolidation phases. The consolidation therapy included Realgar-Indigo naturalis formula (60 mg/kg daily in an oral divided dose) in a 4-week-on and 4-week-off regimen for 4 cycles and ATRA (25 mg/m2 daily in an oral divided dose) in a 2-week-on and 2-week-off regimen for 7 cycles. The primary end point was the disease-free survival (DFS). Secondary end points included measurable resident disease, overall survival (OS), and safety. A total of 54 participants were enrolled at seven centers from May 2019. The median age was 40 years. At the median follow-up of 13.8 months (through April 2022), estimated 2-year DFS and OS were 94% and 100% in an intention-to-treat analysis. All the patients achieved complete molecular remission at the end of consolidation phase. Two patients relapsed after consolidation with a cumulative incidence of relapse of 6.2%. The majority of adverse events were grade 1-2, and only three grade 3 adverse events were observed. Oral arsenic plus ATRA without chemotherapy was active as a first-line consolidation therapy for high-risk APL.Trial registration: chictr.org.cn number, ChiCTR1900023309.

Successful treatment of hyperglycemia with liraglutide in a hospitalized 27-year-old patient with schizophrenia: A case report.

BACKGROUND: Antipsychotics are associated with abnormalities in glucose metabolism in patients with schizophrenia. Liraglutide, a GLP-1 receptor agonist, is Food and Drug Administration approved for the treatment of type 2 diabetes mellitus. However, ways to maintain the long-term stability of psychotic symptoms and balance the disadvantages of obesity, diabetes, and other metabolic disorders caused by antipsychotic medications remain unclear. In this study, we present a case of weight gain and hyperglycemia in a schizophrenia patient who received antipsychotic polypharmacy for 6 years. CASE SUMMARY: A 27-year-old man with olanzapine and sodium valproate-treated disorganized schizophrenia was admitted to a diabetes outpatient clinic. He was diagnosed with type 2 diabetes (fasting blood glucose, 20 mmol/L) and obesity (body mass index, 38.58 kg/m2). The patient had been treated with glargine (40 IU/d) and metformin (1.5 g/d) and showed a poor response for 2 mo. Two years of liraglutide treatment resulted in stable blood glucose levels and weight loss in addition to a maintained stable mental status for a long time. The biological activities of GLP-1 significantly improved glucose levels and body weight in the schizophrenia patient treated with antipsychotic medications. CONCLUSION: Liraglutide administration can be considered an effective alternative treatment for abnormalities in glucose metabolism in schizophrenia patients receiving antipsychotics.

Comparative Ubiquitome Analysis Reveals Deubiquitinating Effects Induced by Wolbachia Infection in Drosophila melanogaster.

The endosymbiotic Wolbachia bacteria frequently cause cytoplasmic incompatibility (CI) in their insect hosts, where Wolbachia-infected males cross with uninfected females, leading to no or fewer progenies, indicating a paternal modification by Wolbachia. Recent studies have identified a Wolbachia protein, CidB, containing a DUB (deubiquitylating enzyme) domain, which can be loaded into host sperm nuclei and involved in CI, though the DUB activity is not necessary for CI in Drosophila melanogaster. To investigate whether and how Wolbachia affect protein ubiquitination in testes of male hosts and are thus involved in male fertility, we compared the protein and ubiquitinated protein expressions in D. melanogaster testes with and without Wolbachia. A total of 643 differentially expressed proteins (DEPs) and 309 differentially expressed ubiquitinated proteins (DEUPs) were identified to have at least a 1.5-fold change with a p-value of <0.05. Many DEPs were enriched in metabolic pathway, ribosome, RNA transport, and post-translational protein modification pathways. Many DEUPs were involved in metabolism, ribosome, and proteasome pathways. Notably, 98.1% DEUPs were downregulated in the presence of Wolbachia. Four genes coding for DEUPs in ubiquitin proteasome pathways were knocked down, respectively, in Wolbachia-free fly testes. Among them, Rpn6 and Rpn7 knockdown caused male sterility, with no mature sperm in seminal vesicles. These results reveal deubiquitylating effects induced by Wolbachia infection, suggesting that Wolbachia can widely deubiquitinate proteins that have crucial functions in male fertility of their hosts, but are not involved in CI. Our data provide new insights into the regulatory mechanisms of endosymbiont/host interactions and male fertility.

A real-world study of infectious complications of venetoclax combined with decitabine or azacitidine in adult acute myeloid leukemia.

PURPOSE: The purpose of this study was to identify the incidence, sites and main pathogens, and risk factors for infectious complications occurring in patients with adult acute myeloid leukemia (AML) during the first course of venetoclax combined with decitabine or azacitidine. METHODS: A retrospective cohort analysis was performed of 81 patients with AML older than 14 years who received the first cycle of venetoclax combined with a hypomethylating agent (HMA) between March 2018 and March 2021 at our institution. Infectious complications, if any, were documented. RESULTS: Among a total of 81 cases of AML, 59 (72.8%) patients occurred infections, including fever without an identifiable source (28.8%), clinically documented infections (40.7%), and microbiologically documented infections (30.5%). The most commonly isolated organism in culture was Candida albicans, followed by Klebsiella pneumonia, and Pseudomonas aeruginosa. The 4-week and 8-week mortality rates were 3.7% and 7.4%, respectively. In multivariate analysis, a high proportion of blasts in bone marrow, decreased hemoglobin level, and fever with or without a documented infection at baseline were significant independent risk factors for infectious complications. CONCLUSION: Compared with conventional chemotherapy, the incidence of infectious complications of venetoclax combined with decitabine or azacitidine significantly decreased. Pretreatment high leukemia burden and fever were independent risk factors for infections.

CDKN2A deletions are associated with poor outcomes in 101 adults with T-cell acute lymphoblastic leukemia.

The identification of genetic risk subgroups of T-cell acute lymphoblastic leukemia (T-ALL) may provide evidence for risk stratification and individualized treatment. We investigated the characteristics and prognostic value of tumor suppressor gene CDKN2A deletions in 101 patients with T-ALL. The CDKN2A deletion was present in 23% (23/101) of T-ALL by fluorescence in situ hybridization (FISH). The most common type of CDKN2A deletion was homozygous deletion (70%, 16/23). A lower frequency of CDKN2A deletion was found in patients with early T-cell precursor (ETP) ALL than in patients with non-ETP-ALL (10.4% vs 34.0%; P = .008). Deletion of CDKN2A was significantly associated with younger age (P = .001), higher white blood cell (WBC) count (P < .001) and higher lactate dehydrogenase (LDH) level (P = .002). Patients with CDKN2A deletion had lower 2-year overall survival (OS) and event-free survival (EFS) rates than patients without CDKN2A deletion (2-year OS: 18.6% ± 8.9% vs 47.4% ± 6.2%, P = .032; EFS: 16.4 ± 8.3 vs 38.6 ± 5.9%, P = .022). In multivariable analysis, CDKN2A deletion was an independent adverse prognostic factor for OS (P = .016). In conclusion, adult T-ALL patients with CDKN2A deletion had a poor prognosis, and these patients might benefit from intensive chemotherapy or allogeneic hematopoietic stem-cell transplantation.

Comparison of Early T-Cell Precursor and Non-ETP Subtypes Among 122 Chinese Adults With Acute Lymphoblastic Leukemia.

Background: Adult T-cell acute lymphoblastic leukemia (T-ALL) is a rare hematological malignancy and significantly linked to poor outcomes. Early T-cell precursor (ETP) leukemia is a unique subtype of T-ALL. The aim of this study is to compare the differences between ETP and non-ETP ALLs in China. Methods: We retrospectively analyzed the records of 122 adult T-ALL patients diagnosed and treated at our center between January 2014 and June 2019. All the patients enrolled were categorized into ETP and non-ETP ALL by immunophenotype, and further statistical analyses about clinical data and prognostic factors were performed. Results: Among the 122 cases, the male-to-female ratio was 2.8:1, and the median age is 29 (range, 16-82) years. Except for 10 patients with insufficient immunophenotyping results, 47.3% (53/112) are ETP and 52.7% (59/112) are non-ETP. Compared with non-ETP patients, ETP-ALL patients had lower white blood cell counts and lactate dehydrogenase levels, while they were older and had higher platelet counts and fibrinogen levels (all p < 0.05). Complete remission (CR) was achieved in 68.0% (83/122) of patients, 64.2 and 76.3% in ETP and non-ETP, respectively (p = 0.160). In total, 44.6% (37/83) of patients relapsed. Allogeneic stem cell transplantation (allo-SCT) was successfully performed in 36.1% (44/122) of patients, of which 79.5% (35/44) were in CR1. With a median follow-up of 9.1 (range, 0.5-70.3) months, the estimated 2-year overall survival (OS) and relapse-free survival (RFS) rates for the cohort were 38.0 ± 5.1 and 39.1 ± 6.3%, respectively. In the ETP group, the 2-year OS rate was 40.7 ± 8.2% and the RFS rate was 47.2 ± 10.7%, while in the non-ETP group, the 2-year OS rate was 37.9 ± 7.0% and the RFS rate was 39.2 ± 8.3% (both p > 0.05). In the landmark analysis of CR1 patients who had a survival of more than 6 months, the allo-SCT group had significantly better survival outcomes than the chemotherapy group, and the 2-year OS rates and RFS rates were 80.1 ± 7.3 vs. 28.4 ± 8.4% and 68.9 ± 8.8 vs. 12.8 ± 7.2%, respectively (both p < 0.0001). A multivariate analysis suggests that allo-SCT acts as an independent prognostic factor for both OS and RFS. Conclusions: Our results revealed that ETP accounted for a high proportion of T-ALL in Chinese. There are no CR rates and prognosis differences between ETP and non-ETP. Allo-SCT in CR1 can significantly improve patients' survival.

Characteristics of chemotherapy-induced diabetes mellitus in acute lymphoblastic leukemia patients.

Acute lymphocytic leukemia (ALL) is one of the most common malignancies, especially in young people. Combination chemotherapy for ALL typically includes corticosteroids (Kantarjian et al., 2000). Hyperglycemia is a well-recognized complication of corticosteroids, and chemotherapy-induced diabetes (CID) is not uncommon (27.5%-37.0%) during the treatment of ALL (Hsu et al., 2002; Weiser et al., 2004; Alves et al., 2007). Besides the effect of corticosteroids, potential factors triggering hyperglycemia in ALL also include direct infiltration of the pancreas by leukemia cells and ß cell dysfunction induced by chemotherapeutic agents such as L-asparagine (Mohn et al., 2004).

Risk factors of hyperprolactinemia induced by risperidone and olanzapine and their correlations with plasma glucose and lipids.

BACKGROUND: Hyperprolactinemia is a common adverse reaction in patients with schizophrenia who take antipsychotic drugs; it often leads to treatment non-compliance in patients and has an adverse effect on their prognosis. AIMS: This study aimed to explore the risk factors of elevated prolactin (PRL) caused by risperidone (RIS) and olanzapine (OLZ) and the relationship between PRL and fasting plasma glucose and lipids. METHODS: Patients with schizophrenia were divided into two groups: 264 patients who were taking RIS and 175 patients who were taking OLZ. These two groups were further divided according to serum PRL levels: an elevated PRL group (>30 ng/mL) and a normal PRL group (PRL ≤30 ng/mL). The demographics, medication dosage, fasting plasma glucose, total cholesterol and triglycerides were compared in the two groups. Logistic regression analysis was performed to explore the risk factors of elevated PRL levels. RESULTS: Compared with the OLZ group, the RIS group had a greater number of patients with elevated PRL (155/264 vs 58/175). Either the RIS or the OLZ group, the proportion of elevated PRL was greater in female patients (RIS: χ2=6.76, p=0.009; OLZ: χ2=12.98, p<0.001) and with higher doses of the related drugs (RIS: U=-3.73, p<0.001; OLZ: U=-2.31, p=0.021). In patients taking RIS, the elevated PRL subgroup took the drug for a longer period (U=-2.76, p=0.006) and had lower triglyceride levels (U=2.76, p=0.006). In patients taking OLZ, the elevated PRL subgroup had lower fasting plasma glucose levels (U=2.29, p=0.022). Logistic regression analysis showed that gender, dose and fasting glucose levels were significantly associated with elevated PRL levels (RIS: p=0.001, OLZ: p<0.001; RIS: p<0.001; OLZ: p=0.003; RIS: p=0.020, OLZ: p=0.001, respectively). CONCLUSION: Compared with OLZ, RIS had a greater effect on PRL in patients with schizophrenia, and in patients with schizophrenia taking RIS or OLZ, gender and dose were significantly correlated with the PRL value. Moreover, the plasma glucose level of the group with elevated PRL was lower than that of the group with normal PRL. The results also showed that high serum PRL may be associated with a favourable glucose metabolic profile in patients with schizophrenia taking RIS or OLZ. Further studies are warranted to confirm this association. TRIAL REGISTRATION NUMBER: NCT02640911.

Malignant melanotic Xp11 neoplasms exhibit a clinicopathologic spectrum and gene expression profiling akin to alveolar soft part sarcoma: a proposal for reclassification.

The classification of the distinct group of mesenchymal neoplasms, first described as 'Xp11 translocation perivascular epithelioid cell tumor (PEComa)' and for which the term 'melanotic Xp11 neoplasm' or 'Xp11 neoplasm with melanocytic differentiation' has recently been proposed, remains challenging and controversial. We collected 27 melanotic Xp11 neoplasms, the largest series to date, for a comprehensive evaluation. Fourteen of the cases, together with eight alveolar soft part sarcomas (ASPS), nine conventional PEComas and a control group of seven normal tissues were submitted to RNA sequencing. Follow-up available in 22 patients showed 5-year overall survival and 5-year disease-free survival of 47.6 and 35.7%, respectively, which were similar to ASPS and significantly worse than conventional PEComa. Univariate analysis of location (occurring in the kidney versus not kidney), infiltrative growth pattern, nuclear pleomorphism, mitotic activity ≥2/50 high-power fields (HPF), necrosis and lymphovascular invasion were found to be associated with overall survival and/or disease-free survival. Multivariate analysis identified that location was the only factor found to independently correlate with disease-free survival. More importantly, RNA sequencing-based clustering analysis segregated melanotic Xp11 neoplasm and ASPS from other tumors, including conventional PEComa and Xp11 translocation renal cell carcinoma, and formed a compact cluster representative of the largely similar expression signature. Here we clearly define the true biologic nature of melanotic Xp11 neoplasms which are distinctive malignant mesenchymal tumors, rather than simply PEComa variants with occasionally unpredictable behavior. Meanwhile, melanotic Xp11 neoplasm and ASPS more likely represent phenotypic variants of the same entity, which is distinct from conventional PEComa and Xp11 translocation renal cell carcinoma. Based on these important findings, melanotic Xp11 neoplasm might be reclassified into a distinctive entity together with ASPS, independent from PEComa, in future revisions of the current WHO categories of tumors of soft tissue and bone for the improved reclassification. © 2020 Pathological Society of Great Britain and Ireland.

[Analysis on Factors Influencing Posttransfusion Effectiveness in Plasma Transfusion of 4 423 Cases-Times].

OBJECTIVE: To investigate the related factors influencing plasma transfusion efficacy so as to improve the plasma transfusion efficiency. METHODS: According to the clinical symptoms and the laboratorial results, the patients were divided into transfusion efficient and inefficient groups. A total of13090.8 units of plasma were transfused to 4423 patients. The clinical symptoms and the hemorrhage related index per- and pro-transfusion, plasma components sorts, storage time, and the dose of plasma (kg/ml) transfusion were analyzed. RESULTS: The largest transfusion volume of plasma were in intensive care unit (ICU) accounted for 30.36%, the largest blood plasma per patient transfusion was in cardiac surgery (3.96 U). The analysis of transfusion efficiency showed that in terms of patient age, there were difference in transfusion efficiency among the patients with different ages (P＜0.001). The effective transfusion rate in the group of age ＜18 was 53%, which was higher than that in group of age 18-60(41%) and group of age ＞60 (30%); in terms of sex, the effective transfusion rate in female group was higher than that in male group (42% vs 37%) (P＜0.001); in terms of transfusion plasma volume/body weight, there were differences in transfusion efficiency (P＞0.05). The multi-factor logistic regression analysis showed that there was no significant correlation among the plasma sorts, storage time of the plasma pre-transfusion and transfusion efficiency(P＞0.05). The analysis of the non-hemolytic fever reaction caused by plasma transfusion revealed that there was no statistical difference between the plasma and the leukocyte-depleted plasma groups (P＞0.05). CONCLUSION: The plasma transfusion effectiveness relates with age and sex, but not relates with the transfusion plasma voume/body weight, plasma sorts, and the duration of storage.

Combined effect of n-3 fatty acids and phytosterol esters on alleviating hepatic steatosis in non-alcoholic fatty liver disease subjects: a double-blind placebo-controlled clinical trial.

The aim of this study was to investigate the combined effect of n-3 fatty acids (EPA and DHA, at an EPA:DHA ratio of 150:500) and phytosterol esters (PS) on non-alcoholic fatty liver disease (NAFLD) patients. We conducted a randomised, double-blind, placebo-controlled trial. Ninety-six NAFLD subjects were randomly assigned to the following groups: the PS group (receiving 3·3 g/d PS); the FO group (receiving 450 mg EPA + 1500 mg DHA/d); the PS + FO combination group (receiving 3·3 g/d PS and 450 mg EPA + 1500 mg DHA/d) and the PO group (a placebo group). The baseline clinical characteristics of the four groups were similar. The primary outcome was liver:spleen attenuation ratio (L:S ratio). The percentage increase in liver-spleen attenuation (≤1) in the PS + FO group was 36 % (P = 0·083), higher than those in the other three groups (PS group, 11 %, P = 0·519; FO group, 18 %, P = 0·071; PO group, 15 %, P = 0·436). Compared with baseline, transforming growth factor-ß (TGF-ß) was significantly decreased in the three study groups at the end of the trial (PS, P = 0·000; FO, P = 0·002; PS + FO, P = 0·001) and TNF-α was significantly decreased in the FO group (P = 0·036), PS + FO group (P = 0·005) and PO group (P = 0·032) at the end of the intervention. Notably, TGF-ß was reduced significantly more in the PS + FO group than in the PO group (P = 0·032). The TAG and total cholesterol levels of the PS + FO group were reduced by 11·57 and 9·55 %, respectively. In conclusion, co-supplementation of PS and EPA + DHA could increase the effectiveness of treatment for hepatic steatosis.

Clinical features and treatment of 7 Chinese TAFRO syndromes from 96 de novo Castleman diseases: a 10-year retrospective study.

BACKGROUND: Castleman disease (CD) is a rare polyclonal lymphoproliferative disorder with unknown etiology. TAFRO syndrome is now regarded as a specific subtype of CD, and is still a huge challenge for clinicians. METHODS: To clarify the clinical features and management of TAFRO syndrome in China, we retrospectively analyzed 96 patients with HIV-negative CD (52 with unicentric CD and 44 with multicentric CD), who were diagnosed and treated at our center between 2008 and 2017. Specially, we systematically reviewed the 7 TAFRO syndrome cases based on the 2015 criteria proposed by Masaki. RESULTS: Among the 7 cases, there were 3 men and 4 women, and the median age was 53 years. The main symptoms included thrombocytopenia (7/7), anasarca (7/7), fever (4/7), renal dysfunction (7/7), and organomegaly (6/7). One patient was treated with corticosteroid monotherapy, one received RD (Rituximab, dexamethasone), and 5 received CHOP/COP like chemotherapy as first-line treatment, 2 of the 5 combined with Rituximab. Four patients needed hemodialysis or CRRT because of progressive renal failure. The outcome for TAFRO syndrome was significantly worse compared to other types of CD. Although 3 patients improved after early treatment, 4 patients died due to disease progression, and only one patient achieved complete resolution of all the symptoms after changing to lenalidomide based regimen. CONCLUSIONS: This study reveals that TAFRO syndrome is more severe and has more systemic symptoms than other iMCD, most cases need active treatment, and their prognoses are poor. Lenalidomide based regimen may be as a promising new therapy for TAFRO syndrome.

A novel prognostic scoring model for newly diagnosed FLT3-ITD-positive acute myeloid leukemia.

FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) is one of the most common somatic mutations in acute myeloid leukemia (AML). However, the molecular structure characteristics and widely accepted prognostic factors for FLT3-ITD are still not well described. This study aimed to retrospectively examine 81 patients with FLT3-ITD-positive AML diagnosed and treated at the First Affiliated Hospital of Zhejiang University from December 2013 to March 2018 using the next-generation sequencing 185-gene platform. High variant allele frequency (VAF) [> 0.48, P = 0.0089 for overall survival (OS), P = 0.13 for relapse-free survival (RFS)], multiple ITDs (> 1 ITDs, P = 0.011 for OS, P = 0.033 for RFS) and longer insertion length (> 69 bp, P = 0.14 for OS, P = 0.0078 for RFS) predicted poor survival. The study further proposed an easily applicable scoring model for OS using the Least Absolute Shrinkage and Selector Operation (LASSO) Cox regression model. Also, an independent cohort of 30 patients was used for external model validation. The mode was expressed as follows: 0.659 × FLT3-ITD VAF + 0.375 × FLT3-ITD number + 0.807 × Age + 0.688 × DNMT3A + 1.939 × U2AF1 (FLT3-ITD VAF > 0.48 scored 1; FLT3-ITD number scored 1 if carried 1 ITD, 2 if carried ≥ 2 ITDs; age > 44 years scored 1, the presence of DNMT3A or U2AF1 scored 1; 0 for other conditions). It categorized patients into low-risk (L-R, score < 1, n = 20) and high-risk (H-R, score ≥ 1, n = 61) groups based on the risk score with a significant difference in survival (3-year OS, P < 0.0001; 3-year RFS, P = 0.0005). A prognostic nomogram that integrated these five factors was developed with a concordance index calculation [OS: 0.68, 95% CI (0.64-0.72)].
