OBJECTIVE: To analyze the reliability of the Water Tank Scale for assessing recovery of motor function after spinal cord injury (SCI) in rats. METHODS: Thirty-six adult female SD rats were randomly divided into SCI and sham-operated groups (n= 18). The recovery of the hind limb motor function was assessed using Water Tank scoring, BBB scoring, and motor-evoked potentials (MEP) at 1, 3, 5, 7, 14 and 21 days after SCI. MEP was used as the gold standard for analyzing and comparing differences between the two scoring methods. RESULTS: The Water Tank scores of the rats were significantly higher than the BBB scores on day 3 (0.22±0.43 vs 0, P < 0.05) and also on days 5, 7 and 14 after SCI (0.67±0.49 vs 0.11±0.32, 4.33±1.19 vs 2.83±1.04, 8.61± 1.20 vs 7.06±1.0, P < 0.01). On day 21 after SCI, the scores of the Water Tank Scale of the rats did not significantly differ from the BBB scores (14.78±1.06 vs 14.50±1.47, P>0.05). Neurophysiological monitoring showed that both the Water Tank score and BBB score were significantly correlated with MEP latency, but the Water Tank score had a greater correlation coefficient with MEP latency (r=-0.90). CONCLUSION Compared with the BBB scale, Water Tank scoring allows more objective and accurate assessment of functional recovery of the spinal cord in early stages following SCI in rats, and can thus be used as a reliable method for assessing functional recovery of the hind limbs in rat models of acute SCI.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective : To identify the main components in the extracts of different parts of Juandan Baihe (Lilium lancifolium) by ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) technology and investigate their hypoglycemic activities. Methods: The MS fragmentation pathways of the main types of compounds in Juandan Baihe (Lilium lancifolium) were studied, and the main components in the extracts were systematically identified using MS fragmentation pathways combined with MS mining technology. Based on the hyperglycemia male mouse model [specific pathogen free (SPF)-grade Kunming mice] induced by streptozotocin (intragastric administration of 80 mg/kg for 3 d), the hypoglycemic effects of extracts of Juandan Baihe (Lilium lancifolium) roots, stems, corms, leaves, and flowers were evaluated by measuring the changes of blood glucose, daily water consumption, daily food intake, and body weight. Result: The MS fragmentation pathways of regalosides, dioscins, phenylpropanoids, flavonoids, and chlorogenic acids in Juandan Baihe (Lilium lancifolium) were clarified, and a mining method for compounds in this plant was constructed. A total of 58 compounds, including 6 chlorogenic acids, 14 regalosides, 13 phenylpropanoids, 5 flavonoids, and 20 dioscins, were identified from the roots, stems, corms, leaves, and flowers of Juandan Baihe (Lilium lancifolium). Among them, 30 compounds were reported for the first time from this plant. The root and corm extracts demonstrated significant hypoglycemic activities by reducing blood glucose levels from 23.76 ± 1.21 and 24.29 ± 1.35 mmol/L to 17.21 ± 1.23 and 18.78 ± 1.49 mmol/L, respectively (P < 0.05). The roots and corms extracts could also attenuate the symptoms of polydipsia (P < 0.01), polyphagia (P < 0.05), and weight loss caused by diabetes. Conclusion This study clarifies that the roots of Juandan Baihe (Lilium lancifolium) are rich in regalosides and dioscins for the first time, and have significant hypoglycemic activities, providing the foundation for the comprehensive utilization of this plant and the development of hypoglycemic drugs.

Objective: To comprehensively assess the current status of extrauterine growth restriction (EUGR) in very preterm infants (VPI) and its associated factors in Chinese neonatal intensive care units (NICU). Methods: In this cohort study, 6 179 preterm infants born at <32 weeks' gestation were included, who were admitted to 57 hospitals in the China Neonatal Network in 2019 and hospitalized for ≥7 days. EUGR was evaluated by a cross-sectional definition (weight at discharge<10^th percentile for postmenstrual age), a longitudinal definition (decline in weight Z score>1 from birth to discharge), and weight growth velocity. The comparison between infants with and without EUGR was conducted by t-test, Mann-Whitney U test or χ² test as appropriate. Multivariable Logistic regression models were used to evaluate associations between EUGR with different definitions and maternal and neonatal factors, clinical practices, and neonatal morbidities. Results: A total of 6 179 VPI were enrolled in the study, with a gestational age of (29.8±1.5) weeks and birth weight of (1 365±304) g; 56.2% (3 474) of them were male. Among them, 48.4% (2 992 VPI) were cross-sectional EUGR and 74.9% (4 628 VPI) were longitudinal EUGR. Z score of weight was (0.13±0.78) at birth and decrease to (-1.35±0.99) at discharge. The weight growth velocity was 10.13 (8.42, 11.66) g/(kg·d). Multivariate Logistic regression analysis showed that among the influential factors that could be intervened after birth, late attainment of full enteral feeds (OR_adjust=1.01, 95%CI 1.01-1.02, P<0.001; OR_adjust=1.01, 95%CI 1.01-1.02, P<0.001), necrotizing enterocolitis≥Ⅱstage (OR_adjust=2.64, 95%CI 1.60-4.35, P<0.001; OR_adjust=1.62, 95%CI 1.10-2.40, P<0.001) and patent ductus arteriosus (OR_adjust=1.94, 95%CI 1.50-2.51, P<0.001; OR_adjust=1.63, 95%CI 1.29-2.06, P<0.001) were all associated with increased risks of both cross-sectional and longitudinal EUGR. In addition, late initiation of enteral feeds (OR_adjust=1.06, 95%CI 1.02-1.09, P=0.020) and respiratory distress syndrome (OR_adjust=1.45, 95%CI 1.24-1.69, P<0.001) were all associated with cross-sectional EUGR. Breast milk feeding (OR_adjust=1.33, 95%CI 1.05-1.68, P<0.001) was associated with a higher risk of longitudinal EUGR. Conclusions: The incidence of EUGR in VPI in China is high. Some modifiable risk factors provide priorities to improve postnatal growth for VPI. Nutritional management of VPI and the efforts to decrease the incidence of complications are still the focus of clinical management in China.

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 analyze the efficacy and safety of flumatinib in the treatment of patients with chronic myeloid leukemia (CML). METHODS: The clinical data of 56 CML patients treated with flumatinib from January 2020 to December 2021 in the First Affiliated Hospital of Nanchang University were retrospectively analyzed. Patients were divided into three groups: 35 new diagnosed CML patients treated with flumatinib (group A), 10 patients with imatinib/dasatinib intolerance (group B) and 11 patients with imatinib/dasatinib resistance (group C) switched to flumatinib treatment, respectively. The molecular response and adverse effects of flumatinib treatment were evaluated. RESULTS: In group A, the early molecular response (EMR) at 3 months was 40.0%, and the major molecular response (MMR) at 6 and 12 months was 43.7% and 46.2%, respectively. In group B, the EMR was 50.0% at 3 months, and the MMR was 70.0% and 66.2% at 6 and 12 months, respectively. Among evaluable patients, 6 cases in group B achieved molecular response of 4.5 (MR4.5) at 12 months after switching to flumatinib treatment. In group C, 3 cases who switched from imatinib resistance to flumatinib achieved MR4.5 at 12 months, but 2 cases who switched from dasatinib resistance to flumatinib failed. Subgroup analysis showed significant differences in EUTOS long-term survival (ELTS) scores for patients in the medium-risk/high-risk group compared with those in the low-risk group for 3-month EMR (18.8% vs 57.9%), 6-month MMR (15.4% vs 63.2%) and 12-month MR4.5 (15.4% vs 69.2%) (P =0.036, P =0.012,P =0.015). The most common adverse effect in group A was thrombocytopenia, accounting for 54.5%, and 22.8% (8/35) patients discontinued the drug due to haematological adverse effects. Compared with patients who did not discontinue the drug or whose recovery time from discontinuation due to haematological toxicity was <1 month, patients whose recovery time from discontinuation was ≥1 month had a significantly worse 3-month EMR, 6-month MMR and 12-month MR4.5 (P =0.028, P =0.021, P =0.002). CONCLUSIONS Flumatinib has better molecular response and tolerance in patients with primary, imatinib/dasatinib-intolerant or resistant CML. Medium-risk/high-risk in ELTS score and time to recovery from discontinuation due to haematological toxicity ≥1 month are important factors influencing achievement of better molecular response in flumatinib treatment.

OBJECTIVE: To explore the diagnostic value of ¹⁸F-FDG PET/CT in bone marrow infiltration (BMI) of newly diagnosed diffuse large B-cell lymphoma (DLBCL), compared with the results of bone marrow biopsy (BMB) and investigate whether the BMI diagnosed by ¹⁸F-FDG PET/CT and other factors have independent prognostic values. METHODS: Ninety-four newly diagnosed DLBCL patients who underwent PET/CT in Clinical Medical College of Shanghai General Hospital of Nanjing Medical University were included. BMB was performed within 2 weeks before or after PET/CT, and standardized treatment was performed after PET/CT. The manifestations of bone marrow (BM) FDG uptake were recorded. The diagnostic criteria of BMI were BMB positive or focal BM FDG uptake confirmed by imaging follow-up. The relationship between clinical features and BM FDG uptake and the values of PET/CT and BMB in the diagnosis of BMI was analyzed. The progression-free survival (PFS) was analyzed by Kaplan-Meier survival curves, log-rank test was used to compare PFS rate, and Cox regression model was used to analyze the independent risk factors affecting PFS. RESULTS: Among 94 DLBCL patients, 34 patients showed focal BM uptake (fPET), 7 patients showed super BM uptake (sBMU), 11 patients showed diffuse homogenous uptake higher than liver (dPET), and the other 42 patients had normal BM uptake (nPET) (lower than liver). BMB positive was found in all sBMU patients, in 20.6%(7/34) of fPET patients, and in 27.3% (3/11) of dPET patients. All nPET patients had negative BMB results. dPET patients were associated with lower hemoglobin level and leukocyte count compared with nPET group (P < 0.001, P =0.026). Compared with fPET patients, sBMU patients were more likely to have B symptoms and elevated lactate dehydrogenase (LDH). A total of 44 patients were diagnosed BMI, including 17 cases with BMB⁺. The sensitivity and specificity of BMB in the diagnosis of BMI was 38.6% (17/44) and 100% (50/50), respectively. Using fPET and sBMU as criteria of PET BMI, the diagnostic sensitivity and specificity of PET/CT was 93.2% (41/44) and 100% (50/50), respectively. Kaplan-Meier analysis showed that there was no significant difference in 2-year PFS rate between nPET and dPET patients (P >0.05), while sBMU patients had lower 2-year PFS rate compared with fPET patients (P < 0.001). Multivariate analysis showed that higher Ann Arbor stage (HR=9.010, P =0.04) and sBMU (HR=3.964, P =0.002) were independent risk factors affecting PFS. CONCLUSIONS Increased BM FDG uptake of DLBCL can be manifested as dPET, fPET and sBMU. fPET and sBMU can replace BMB to diagnose BMI. Although dPET cannot completely exclude the possibility of BMI, it does not affect the prognosis, so it can be diagnosed as PET BMI negative. sBMU is an independent prognostic risk factor.

OBJECTIVE: To investigate a family with congenital dysfibrinogenemia, and analyze the risk of hemorrhage and thrombosis and blood transfusion strategies. METHODS: Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of the proband and her family members were detected by automatic coagulometer, fibrinogen (Fg) activity and antigen were detected by Clauss method and PT algorithm respectively. Meanwhile, thromboelastometry was analyzed for proband and her family members. Then, peripheral blood samples of the proband and her family members were collected, and all exons of FGA, FGB and FGG and their flanks were amplified by PCR and sequenced to search for gene mutations. RESULTS: The proband had normal APTT and PT, slightly prolonged TT, reduced level of Fg activity (Clauss method). The Fg of the proband's aunt, son and daughter all decreased to varying degrees. The results of thromboelastogram indicated that Fg function of the proband and her family members (except her son) was basically normal. Gene analysis showed that there were 6233 G/A (p.AαArg35His) heterozygous mutations in exon 2 of FGA gene in the proband, her children and aunt. In addition, 2 polymorphic loci were found in the family, they were FGA gene g.9308A/G (p.AαThr331Ala) and FGB gene g.12628G/A (p.BβArg478Iys) polymorphism, respectively. The proband was injected with 10 units of cryoprecipitate 2 hours before delivery to prevent bleeding, and no obvious bleeding occurred during and after delivery. CONCLUSION Heterozygous mutation of 6233G/A (p.AαArg35His) of FGA gene is the biogenetic basis of the disease in this family with congenital dysfibrinogenemia.

OBJECTIVE: To explore the efficacy and survival of venetoclax based (VEN-based) regimen in the treatment of acute myeloid leukemia（AML）. METHODS: A retrospective study was conducted in patients who received VEN-based regimen and completed at least 1 course of efficacy evaluation at the The First Affiliated Hospital of Nanchang University from July 2019 to July 2022. The incidence of complete remission （CR）/CR with incomplete hematologic recovery （CRi） rate, objective remission rate（ORR） and survival of patients with different risk strati- fication and gene subtypes were analyzed. RESULTS: A total of 79 patients were enrolled, including 43 patients with newly diagnosed unfit AML （unfit AML） and 36 relapsed/refractory AML (R/R AML). The median age of the patients was 62(14-83) years old. 36 out of 79 patients achieved CR/CRi and the ORR of the whole cohort was 64.6%. The CR/CRi rate of unfit AML patients was significantly higher than that of R/R AML patients (60.5% vs 27.8%, P=0.004). In unfit AML cohort, the patients with NPM1 and IDH1/2 mutations were benefited, 8 out of 9 patients ahcieved CR/CRi, 7/8 and 5/8 patients achieved minimal residual disease (MRD) negativity, respectively. Six out of 9 patients with TET2 mutation achieved CR/CRi, 3/6 patients achieved MRD negativity. In R/R AML cohort, 2 out of 3 patients with RUNX1 mutation achieved CR/CRi, without MRD negative, while the CR/CRi rate of patients with other gene mutations was lower than 40%. The median follow-up time was 10.1(95%CI: 8.6-11.6) months. In whole cohort, the median overall survival (mOS) time was 9.1 months and the relapse free survival (RFS) time was not reached. The mOS and RFS of unfit AML patients were significantly longer than those of R/R AML patients (14.1 vs 6.8 months, P=0.013; not reached vs 3.3 months, P=0.000). In unfit AML cohort, the mOS of patients with NPM1 or IDH1/2 mutations was not reached, while that of patients without NPM1 or IDH1/2 mutations was 8.0 months (P=0.009; P=0.022). Furthermore, the mOS of patients with TP53 mutaion was significantly shorter than that of patients without TP53 mutation (5.2 vs 14.1 months， P=0.049). In R/R AML cohort, there was no significant difference in mOS between patients with mutation in each gene subtype and those without gene mutation (P>0.05). All patients had hematology adverse reactions, 91.1% patients had AE grade≥3. The most common non-hematology adverse reactions was infection, with an incidence of 91.1%. VEN-based regimen was tolerable for AML patients. CONCLUSION VEN-based regimen can achieve a high response rate, especially in unfit AML with acceptable safety, and some patients can achieve MRD negative. It is also effective in NPM1-, IDH1/2-positive patients with long survival time.
