Traditional Chinese medicine(TCM) decoction pieces are a core carrier for the inheritance and innovation of TCM, and their quality and safety are critical to public health and the sustainable development of the industry. Conventional quality control models, while having established a well-developed system through long-term practice, still face challenges such as relatively long inspection cycles, insufficient objectivity in characterizing complex traits, and urgent needs for improving the efficiency of integrating multidimensional quality information when confronted with the dual demands of large-scale production and precision quality control. With the rapid development of artificial intelligence, machine learning can deeply analyze multidimensional data of the morphology, spectroscopy, and chemical fingerprints of decoction pieces by constructing high-dimensional feature space analysis models, significantly improving the standardization level and decision-making efficiency of quality evaluation. This article reviews the research progress in the application of machine learning in the processing, production, and rapid quality evaluation of TCM decoction pieces. It further analyzes current challenges in technological implementation and proposes potential solutions, offering theoretical and technical references to advance the digital and intelligent transformation of the industry.

Objective: To analyse the clinical effect of endoscopy-assisted functional rhinoplasty. Methods: Twenty-one patients with congenital or traumatic deviated nose with nasal obstruction admitted to Qilu Hospital (Qingdao) from January 2018 to December 2021, including 8 males and 13 females, aged 22 to 46 years, were retrospectively analysed. Endoscopy-assisted functional rhinoplasty was performed in all patients. Deviated nasal septum was corrected, nasal septum cartilage graft was prepared through open approach assisted by endoscopy, the nasal frame structure was adjusted with the endoscopy-assisted rhinoplasty combined with middle and inferior turbinoplasty, and the patient's nasal ventilation function and external nose cosmetology were restored. Visual Analogue Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE), nasal acoustic reflex and nasal resistance were examined preoperatively and 6 months postoperatively. The minimum cross-sectional area of the first two nasal cavities (MCA) MCA1 and MCA2 and their distance between nostrils to the minimum cross-sectional area (MD) MD1 and MD2 were recorded, and the ratio of both sides (expressed in a/b) was calculated. The nasal volume of 5 cm depth from nostril (NV5) and nasal resistance total (RT) were recorded to evaluate the nasal ventilation function to analyse the clinical effect of functional rhinoplasty assisted by nasal endoscope. SPSS 25.0 software was used for statistical analysis. Results: At 6 months after the operation, for nasal ventilation evaluation, the VAS and NOSE scores of nasal obstruction decreased significantly than those before the operation ((1.81±0.81) points vs (6.71±1.38) points, (4.19±2.06) points vs (12.05±2.67) points, all P<0.05). In the objective indexes, MCA1, MCA2 and NV5 were significantly increased whereas RT, MCA1a/MCA1b, MCA2a/MCA2b, MD1a/MD1b and MD2a/MD2b were significantly decreased compared with those before the operation (all P<0.05). The MD1 and MD2 levels before and after operation had no significant differences (all P>0.05). In the evaluation of external nose morphology, postoperative ROE was significantly increased, and the deviation value of nasal appearance was significantly decreased ((16.19±2.56) points vs (10.24±3.24) points, (1.55±1.16) mm vs (5.63±2.41) mm, all P<0.05). In terms of postoperative patient satisfaction, 19 cases (90.5%) were very satisfied with nasal ventilation function, 2 cases (9.5%) were satisfied with nasal ventilation function; 15 cases (71.4%) were very satisfied with nasal appearance, and 6 cases (28.6%) were satisfied with nasal appearance. Conclusions: Nasal endoscopy-assisted functional rhinoplasty can improve the nasal ventilation function and external nasal morphology at the same time, with good clinical effect and high patient satisfaction.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective:To analyze the application effect of information health education combined with teach-back method in patients with posterior fossa tumor during perioperative period and provide experience and reference for clinical practice.Methods:From March 2022 to October 2022, a total of 80 patients diagnosed as posterior fossa tumors in the neurosurgery department were divided into a control group and an experimental group, with 40 patients in each group to conduct an experimental research, based on the length of hospitalization. The control group was given the conventional health education combined with the teach-back method, and the experimental group was given the information health education combined with the teach-back method. The scores of standard swallowing assessment, quality of life, awareness score of health education and incidence of respiratory aspiration were compared between the two groups.Results:On the 7th day after surgery and 1 day before discharge, the standard swallowing score of the experimental group were 25.29 ± 2.21 and 22.97 ± 3.36, which was significantly lower than that of the control group 26.45 ± 2.01 and 24.92 ± 3.56, ( t=2.44, 2.52, both P<0.05). The total score of quality of life on the day before discharge was 64.55 ± 4.27, significantly higher than 61.80 ± 4.82 in the control group, with a statistically significant difference ( t=-2.09, P<0.05). The patients in the experimental group were familiar with preoperative guidance, various dietary requirements, various drug effects and precautions, the prevention of various complications, various rehabilitation training methods, and the purpose and precautions of the head drainage tube, with the score of 4.70 ± 0.56, 4.52 ± 0.71, 4.65 ± 0.57, 4.67 ± 0.52, 4.72 ± 0.50, 4.77 ± 0.47, were higher than the control group 3.40 ± 1.05, 3.62 ± 0.97, 3.77 ± 0.94, 3.80 ± 0.88, 3.75 ± 0.89, 3.92 ± 0.88. The difference was statistically significant ( t values were -6.86 to -4.69, all P<0.05). The incidence of respiratory aspiration in experimental group was 0, significantly lower than that in control group 12.5%(5/40) ( χ2=5.33, P<0.05). Conclusions:The application of information health education combined with back teaching can improve the quality of life, health education awareness rate and reduce the incidence of aspiration in patients with posterior fossa tumor.

OBJECTIVE: To explore the effect of abnormal miRNA expression on the proliferation of pediatric acute lymphoblastic leukemia (ALL) cells and its related mechanism. METHODS: 15 children with ALL and 15 healthy subjects were collected from the Second Affiliated Hospital of Hainan Medical University from July 2018 to March 2021. MiRNA sequencing was performed on their bone marrow cells, and validated using qRT-PCR. MiR-1294 and miR-1294-inhibitory molecule (miR-1294-inhibitor) were transfected into Nalm-6 cells, and the proliferation of Nalm-6 cells was detected by CCK-8 and colony formation assays. Western blot and ELISA were used to detect apoptosis of Nalm-6 cells. Biological prediction of miR-1294 was performed to find the target gene, which was verified by luciferase reporter assay. Si-SOX15 was transfected into Nalm-6 cells, Western blot was used to detect the expression of Wnt signaling pathway-related proteins and to verify the effect of si-SOX15 on the proliferation and apoptosis of Nalm-6 cells. RESULTS: Compared with healthy subjects, 22 miRNAs were significantly upregulated in bone marrow cells of ALL patients, of which miR-1294 was the most significantly upregulated. In addition, the expression level of SOX15 gene was significantly reduced in bone marrow cells of ALL patients. Compared with the NC group, the miR-1294 group showed increased protein expression levels of Wnt3a and β-catenin, faster cell proliferation, and more colony-forming units, while caspase-3 protein expression level and cell apoptosis were reduced. Compared with the NC group, the miR-1294-inhibitor group showed reduced protein expression levels of Wnt3a and β-catenin, slower cell proliferation, and fewer colony-forming units, while caspase-3 protein expression level was increased and apoptosis rate was elevated. miR-1294 had a complementary base-pair with the 3'UTR region of SOX15 , and miR-1294 directly targeted SOX15 . The expression of miR-1294 was negatively correlated with SOX15 in ALL cells. Compared with the si-NC group, the si-SOX15 group showed increased protein expression levels of Wnt3a and β-catenin, accelerated cell proliferation, and decreased caspase-3 protein expression level and cell apoptosis rate. CONCLUSION MiR-1294 can target and inhibit SOX15 expression, thus activating the Wnt/β-Catenin signaling pathway to promote the proliferation of ALL cells, inhibit cell apoptosis, and ultimately affect the disease progression.

OBJECTIVE: To investigate the effect of hemoglobin (Hb) on the efficacy of chimeric antigen receptor T cell therapy (CAR-T) in patients with multiple myeloma (MM). METHODS: From June 2017 to December 2020, 76 MM patients who received CAR-T therapy in the Department of Hematology, The Affiliated Hospital of Xuzhou Medical University, with complete clinical data and evaluable efficacy, were selected as the research objects. According to the receiver operating characteristic (ROC) curve, the best cut-off value was obtained. The patients were divided into groups on the basis of Hb 105.5 g/L as the cut-off value. The age, sex, serum calcium, β₂-microglobulin, serum creatinine, lactate dehydrogenase (LDH), and the influencing factors of CAR-T treatment efficacy in MM patients were analyzed. RESULTS: Hb was an influencing factor of efficacy. Univariate analysis showed that Hb, LDH, and albumin affected the efficacy of CAR-T therapy. Multivariate analysis showed that Hb ( OR=1.039, 95% CI: 1.002-1.078) and LDH ( OR=1.014, 95% CI: 1.000-1.027) were the influencing factors for the efficacy of CAR-T therapy. CONCLUSION The efficacy of CAR-T therapy in MM patients with low Hb is poor, and Hb is a factor affecting the efficacy of CAR-T therapy.

OBJECTIVE: To investigate the toxicity management and efficacy evaluation of BCMA-chimeric antigen receptor T cells(CART) in the treatment of relapsed and refractory multiple myeloma (MM). METHODS: The efficacy and adverse reactions of 21 patients with MM who received BCMA-CART treatment at the First Affiliated Hospital of Wenzhou Medical University from December 2017 to September 2020 were evaluated, and the efficacy assessment and survival analysis for high-risk patients and non-high-risk patients were evaluated. RESULTS: After infusion of BCMA-CART cells in 21 MM patients, the number of effective cases was 17, of which the complete remission (sCR/CR) was 10, and the partial remission (VGPR/PR) was 7. The median OS time for all patients was 19.4 months, and the median PFS time was 7.9 months. The number of patients with extramedullary disease(EMD), high-risk genetics, and ISS stage Ⅲ were 5, 15 and 8, and the effective number was 3, 11 and 6, respectively. The treatment of 3 patients without high-risk factors was effective. The median OS and median PFS of patients with EMD were 14.2 and 2.5 months, respectively, which were shorter than those of patients without EMD (19.4 months and 8.9 months, respectively). The median OS and median PFS of patients with high-risk cytogenetic factors and ISS Ⅲ were not significantly different from those of non-high-risk patients. Cytokine release syndrane (CRS) occurred in 20 patients, of which 14 cases were Grade 1 CRS, while 6 were Grade 2, no CRS of Grade 3 or above occurred. IL-6 receptor inhibitors were used in 9 patients. All CRS were controlled effectively, and no patients had neurological toxicity. CONCLUSION BCMA-CART is a certain curative effect in the treatment of relapsed and refractory multiple myeloma, and the adverse reactions can be well controlled through close monitoring and timely treatment.

Objective:To investigate the status quo of thriving at work, career resilience and voice behavior in organ transplantation nurses, and mediation effects of thriving at work between the latter two.Methods:From June to August 2018,180 nurses with organ transplant qualification departments in two Grade A hospitals in Fuzhou, Fujian Province were investigated by the general situation survey form, Thriving At Work Scale, Career Resilience Scale and Voice Behavior Scale.Results:The scores of thriving at work, career resilience and voice behavior were 3.68 ± 0.65, 3.56 ± 0.61 and 3.42 ± 0.62. There was a pairwise positive correlation among the three: thriving at work, career resilience and voice behavior( r values were 0.270-0.664, all P<0.05). Thriving at work played a partial mediating role between career resilience and voice behavior ( B values were 0.138-0.611, all P<0.05). Conclusions:Ii is necessary to improve thriving at work, career resilience and voice behavior in organ transplantation nurses. Thriving at work is the intermediary factor between the latter two. The improvement of thriving at work and career resilience will help to promote organ transplant specialist nurses to make positive voice behavior.

OBJECTIVE: To investigate the expression level and prognostic value of miR-21, miR-18a, miR-146a, and Let-7b derived from serum exosomes in patients with multiple myeloma (MM). METHODS: Serum exosomes were extracted from 57 MM patients and 20 healthy persons using ExoQuick exosome precipitation solution kit, and the relative expression level of miR-21, miR-18a, miR-146a, and Let-7b derived from serum exosomes was measured by RT-qPCR. Correlations of the expression levels of all miRNAs mentioned above with routine laboratory parameters were analyzed by Spearman correlation analysis. The relationship between the expression level of miR-21, miR-18a, miR-146a, and Let-7b derived from serum exosomes and overall survival of patients with MM was analyzed using the Kaplan-Meier survival curve. RESULTS: The expression levels of miR-21, miR-18a, and Let-7b derived from serum exosomes in patients with MM were significantly lower than those in the normal control group (P<0.001), while the expression level of miR-146a between the two groups was not significantly different (P>0.05). The expression level of miR-21 was strongly negatively correlated with serum β₂-microglobulin concentration (r=-0.830), and weakly negatively correlated with serum creatinine, corrected serum calcium, and cystatin C (r=-0.488, -0.282, -0.627). The expression levels of Let-7b and miR-18a were also weakly negatively correlated with the corrected serum calcium, β₂-microglobulin, and cystatin C concentration (r=-0.305, -0.362, -0.461; -0.317, -0.542, -0.434). However, there was no significant correlation between the expression level of miR-146a and routine laboratory parameters in MM patients. The overall survival rate of MM patients with low expression level of miR-21, miR-18a, and Let-7b significantly decreased compared with high expression level group (P<0.05), however, the expression level of miR-146a was not related to the overall survival rate. CONCLUSION Aberrant low expression levels of miR-21, miR-18a, and Let-7b derived from serum exosomes exist in patients with MM, which are associated with a worse overall survival rate.

OBJECTIVE: To explore the correlation between different body mass index (BMI) and prognosis of mantle cell lymphoma (MCL). METHODS: The clinical characteristics and biological indices of 108 patients with MCL treated in Fujian Medical University Union Hospital were retrospectively analyzed, and the effects of different BMI on overall survival (OS) and progression-free survival (PFS) were analyzed. The correlation between BMI and B symptoms, LDH and Ki-67 was further observed. Furthermore，the differences of BMI between Autologous peripheral blood stem cell transplantation(Auto-PBSCT) and conventional chemotherapy groups were explored. RESULTS: Among 108 patients, the median age at diagnosis was 59（25-79） years old, and the male to female ratio was 4.4∶1. 88.89% of patients with Ann Arbor staging III-IV, 63.89% with bone marrow involvement, and 49.07% with splenic infiltration. Patients with BMI ≥ 24 kg/m² were divided into two groups: the high BMI group and the low BMI group. The 5-year PFS and OS of patients in the low BMI group were 31.9% and 47.0%, respectively, while those in the high BMI group were 64.6% and 68.7%, respectively. The incidence of death in the high BMI group was lower than that of the low BMI group (P＜0.01). In multivariate analysis, BMI was an independent predictor of PFS (HR=0.282; 95% CI: 0.122-0.651; P=0.003) and an independent predictor of OS (HR=0.299; 95% CI: 0.129-0.693; P=0.005). Also, patients with B symptoms had a lower BMI than those without B symptoms (P=0.01), but BMI had no effect on patients' LDH and Ki-67. The prognosis of 16 patients treated with Auto-PBSCT was significantly better than that of the conventional chemotherapy group. There was no significant difference in BMI between Auto-PBSCT group and conventional chemotherapy group. CONCLUSION BMI is an independent prognostic factor for PFS and OS in MCL, and may be influenced by the effect of B symptoms on BMI.
