ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

OBJECTIVE: To explore the efficacy of venetoclax (VEN) plus azacitidine (AZA) in patients with FLT3-ITD mutated relapsed/refractory acute myeloid leukemia (FLT3-ITD^mut R/R AML) and analyze the molecular genetic characteristics of the patients. METHODS: Clinical baseline characteristics and follow-up data of 16 R/R AML patients treatd with VEN plus AZA in the hematology department of Shenzhen Second People's Hospital from November 2018 to April 2021 were collected. Leukemia related genes were detected by next-generation sequencing(NGS) or PCR. The relationship between the efficacy of VEN plus AZA and molecular genetics characteristics of patients with FLT3-ITD^mut R/R AML were analyzed. RESULTS: 14.3% (1/7) of the patients in FLT3-ITD^mut group and 22.2% (2/9) of the patients in FLT3-ITD^wt group achieved complete remission (CR)/CR with incomplete blood count recovery (CRi), respectively, with no significant difference (P=0.69). There was no significant difference in overall response rate (ORR) (CR/CRi+PR) between FLT3-ITD^mut group and FLT3-ITD^wt group [42.9%(3/7) vs 44.4%(4/9), P=0.95], too. The median overall survival (OS) time of FLT3-ITD^mut patients was significantly shorter than that of FLT3-ITD^wt patients (130 vs 300 days, respectively) (P =0.02). Co-existing mutations of FLT3-ITD and IDH1 were detected in one patient who achieved CR. Co-existing mutations of FLT3-ITD and SF3B1 were found in one patient who achieved PR. Three FLT3-ITD^mut R/R AML patients accompanied with NPM1 mutation had no response to VEN plus AZA. CONCLUSION VEN plus AZA showed a certain effect on patients with FLT3-ITD^mut R/R AML. To improve OS of the patients, bridging transplantation is need. IDH1 and SF3B1 mutations might predict that patients with FLT3-ITD^mut R/R AML have treatment response to VEN plus AZA, while the combination of NPM1 mutation may indicate poor response.

The multiple bioactive constituents in leaves, petioles, stems and rhizomes of E. brevicornum were analyzed. The gradient elution was performed at 30 ℃ in an XBridge~® C_(18) column(4.6 mm×100 mm, 3.5 μm) with 0.4% formic acid aqueous solution-acetonitrile as the mobile phase at a flow rate of 0.8 mL·min~(-1). Single factor experiment and response surface methodology were employed to optimize the extraction conditions. Multivariate statistical analyses including systematic cluster analysis(SCA), principal component analysis(PCA), partial least squares discriminant analysis(PLS-DA), and one-way analysis of variance(One-way ANOVA) were carried out to classify the samples from different parts and identify different constituents. Grey relation analysis(GRA) and entropy weight-TOPSIS analysis were performed to build a multi-index comprehensive evaluation model for different parts of E. brevicornum. The results showed that there was a good relationship between the mass concentrations of 45 constituents and the corresponding peak areas, with the correlation coefficients(r) not less than 0.999 0. The precision, repeatability, and stability of the established method were good for all the target constituents in this study, with the relative standard deviations(RSDs) less than 5.0%(0.62%-4.9%) and the average recovery of 94.51%-105.7%. The above results indicated that the bioactive constituents varied in different parts of E. brevicornum, and the overall quality followed the trend of leaves > petioles > rhizomes > stems. This study verified the rationality of the Chinese Pharmacopoeia(2020 edition) stipulating that the medicinal part of E. brevicornum is the leaf. Moreover, our study indicated that the rhizome had the potential for medicinal development. The established method was accurate and reliable, which can be used to comprehensive evaluate and control the quality of E. brevicornum. This study provides data reference for clarifying the medicinal parts and rationally utilizing the resources of E. brevicornum.

ObjectiveTo search for an effective method for cryopreservation of rare human sperm (RHS) by comparing the effect of RHS cryopreservation technology with that of conventional cryopreservation technology on post-thaw sperm from patients with severe oligozoospermia.

METHODSSemen samples obtained from 82 patients with severe oligozoospermia were preserved by RHS cryopreservation technology, and another 24 samples cryopreserved by conventional technology, the former divided into groups A (sperm concentration < 1×10⁶/ml, n = 54) and B (1×10⁶/ml ≤ sperm concentration < 5×10⁶/ml, n = 28), and the latter included in group C (sperm concentration < 15×106 /ml, n = 24). The survival rate of post-thaw sperm and recovery rate of progressively motile sperm (PMS) were compared among the three groups.

RESULTSThe survival rate of post-thaw sperm was significantly higher in groups A and B than in C (［62.8 ± 18.7］% and ［61.9 ± 17.2］% vs ［50.7 ± 13.5］%, P < 0.05), and so was the recovery rate of PMS (［68.7 ± 18.4］% and ［70.7 ± 15.5］% vs ［29.2 ± 12.4］% , P < 0.05), but there were no statistically significant differences between groups A and B in either of the two parameters (P > 0.05).

CONCLUSIONSThe cryopreservation technology for rare human sperm may yield relatively stable post-thaw results and deserves a wide clinical application in preserving male fertility.

Objective To investigate the effect of allogeneic transfusion and preoperative autologous blood donation on perioperative cellular immunity and humoral immunity in patients with gastrointestinal neoplasms.Methods Sixty gastrointestinal cancer patients undergoing radical surgery,33 males and 27 females,aged 53 69 years,weighing 47-70 kg,ASA physical status Ⅰ or Ⅱ,were included in this study.Blood transfusion was started when the blood loss was more than 200～400 ml,Hb＜70 g/L,and the patients were randomly divided into the preoperative autologous blood donation group (group P,n =30):intraoperative blood transfusion using the stored autologous blood transfusion;allogeneic blood transfusion group (group A,n =30):allogeneic blood transfusion.The levels of T lymphocyte subsets,NK cells and IL-2,IL-10,TNF-α,perforin (PF) concentration and plasma immunoglobulin IgG,IgA and IgM levels.Results The percentage of CD3+,CD4+,NK cells and the ratio of CD4+/CD8+ in group A at the end of surgery to 7 d after operation were significantly lower than those at the time of admission (P＜0.05).The percentage of CD3+,CD4+ (P＜ 0.05).The level of IL-2 in group A was significantly lower than that in group P (P＜0.05) 1-7 d after operation,and the level of IL-10 in group A was significantly higher than that in group P (P＜ 0.05).The levels of IgG and IgA 3 d after operation in group A were significantly lower than those in group P (P＜0.05).The levels of IgG and IgA in group P were significantly decreased at the end of operation and recovered to preoperative levels 1-3 d after operation (P ＜ 0.05).Conclusion Allogeneic blood transfusion can reduce the percentage of T-cell subsets and NK cells in cancer patients and delay their recovery,and also can transiently reduce the content of immunoglobulin IgG and IgA in plasma and thus affect the immune function of patients.However,the preoperative autologous blood donation has a slight effect on postoperative immune function in cancer patients.
