Objective: To map the research hotspots, developmental trends, and existing challenges in the integration of artificial intelligence (AI) with multi-omics in traditional Chinese medicine (TCM) through comprehensive bibliometric analysis. Methods: China National Knowledge Infrastructure (CNKI), Wanfang Data, China Science and Technology Journal Database (VIP), Chaoxing Journal Database, PubMed, and Web of Science were searched to collect literature on the theme of AI in TCM multi-omics research from the inception of each database to December 31, 2024. Eligible records were required to simultaneously address AI, TCM, and multi-omics. Quantitative and visual analyses of publication growth, core authorship networks, institutional collaboration patterns, and keyword co-occurrence were performed using Microsoft Excel 2021, NoteExpress v4.0.0, and Cite Space 6.3.R1. AI application modes in TCM multi-omics research were also categorized and summarized. Results: A total of 1 106 articles were enrolled (932 Chinese and 174 English). Publication output has increased continuously since 2010 and accelerated after 2016. Region-specific collaboration clusters were identified, dominated by Beijing University of Chinese Medicine, China Academy of Chinese Medical Sciences, Shanghai University of Traditional Chinese Medicine, and Nanjing University of Chinese Medicine. Keyword co-occurrence analysis revealed that current AI applications predominantly centered on metabolomics and algorithms such as cluster analysis and data mining. Research foci mainly ranked as follows: single herbs, herbal formulae, and disease-syndrome differentiation. Conclusion Machine learning methods are the predominant integrative modality of AI in the realm of TCM multi-omics research at present, utilized for processing omics data and uncovering latent patterns therein. The domain of TCM, in addition to investigating omics information procured through high-throughput technologies, also integrates data on traditional Chinese medicinal substances and clinical phenotypes, progressing towards joint analysis of multi-omics, high-dimensionality of data, and multi-modality of information. Deep learning approaches represent an emerging trend in the field.

Objective To compare the therapeutic effects of bone marrow stem treatment by different bone marrow mobilization,distinct separation methods or cell suspension density, and to explore the optimal treatment plan of autologous bone marrow stem cell transplantation for decompensated cirrhosis.Methods Twenty three patients with decompensated cirrhosis were studied.100 ~200 mL bone marrow from each patient was harvested in aseptic condition, after isolation and purification by density gradient centrifugation,the stem cells were obtained and transplanted into the liver via hepatic artery.The serum glutamic acid alanine aminotransferase (ALT), albumin (ALB), prothrombin time (PT) and total bilirubin (TBIL) were checked before and l, 2, 3 months after therapy respectively,changes in these indicators of each group were compared by different bone marrow mobilization, distinct separation methods, or cell suspension density.Results After transplantation, levels of albumin increased significantly 1, 2, 3 months after treatment compared with baseline(P<0.05).Patients in bone marrow mobilization group obtained higher stem cell density (P<0.05), which had no significant difference in improving liver function ( ALT, TBIL, ALB, PT) compared with non-bone marrow mobilization group.Patients using the kit significantly improved their albumin (3 months after treatment, P<0.05), which had no significant difference in improving liver function (ALT, TBIL, ALB, PT) compared with using ordinary lymphocyte isolation method group.There was no significant difference in improving liver function ( ALT, TBIL, ALB, PT) between lower magnitude stem cell density group(≤1 ×1010/L) and higher magnitude stem cell density group(1 ×1010/L).Conclusion The treatment for decompensated cirrhosis by transplantation of autologous bone nlarrow stem cells is safe and effective, which can significantly increase the level of albumin in patients with decompensated cirrhosis.Preoperative bone marrow mobilization can increase the rate of stem cells obtained, and the method using the kit improves the leves of protein respectively.They are helpful to improve the efficacy.

There exist some problems such as faultiness in system,illogicality in constructing of team,the simple ways and means in teaching inspection.Therefore,the universities in our country must take such measures as system healthiness,team construction,and mechanism function improvement.

OBJECTIVETo explore the effect of exogenous putrescine on renal function and cell apoptosis in rats.

METHODSNinety SD rats were randomized into control group (n=10), high-dose putrescine group (P1 group, n=40), and low-dose putrescine group (P2 group, n=40) with intraperitoneal injections of 2 ml of normal saline, 50 µg/g putrescine, and 25 µg/g putrescine, respectively. At 24, 48, 72 and 96 h after the injections, 10 rats from each group were sacrificed to examine serum Cr and BUN levels, histological changes in the kidneys, and renal cell apoptosis (TUNEL assay).

RESULTSThe rats in the two putrescine- treated groups showed mild edema in some renal tissues without obvious necrosis. In P1 and P2 groups, serum Cr and BUN levels differed significantly at each time point of measurement (P<0.01 and P<0.05, respectively), and were significantly higher than the levels in the control group (P<0.01 and P<0.05, respectively). The two putrescine-treated groups showed gradually increased renal cell apoptosis with time, reaching the peak levels at 96 h and 48 h, respectively. The peak renal cell apoptosis rates in P1 [(24.78∓2.19)%] and P2 [(26.27∓2.13)%] group were significantly higher than the rate in the control group [(4.47∓0.33)%, P<0.01].

CONCLUSIONExogenous putrescine can lead to renal function impairment and induce renal cell apoptosis in rats, and the severity of these changes appeared to be associated with the blood concentration of exogenous putrescine.

To evaluate the absolute quantification of a target gene transcription in engineered lactic acid bacteria, we developed the Real-time RT-PCR based on DNA subtraction. We isolated the total RNA from the bacteria samples by glass bead, and then analyzed the Ct data of real-time RT-PCR by DNA subtraction assay. Using this method, we successfully estimated the expression level of CBHII gene in the strain of genetic engineered Lactococcus lactis. Since this method could avoid the mRNA copy number loss, it could be used to estimate the expression of other genes in lactic acid bacteria.

Objective To investigate the distribution of LAP+CD4+T cells in gastric carcinoma microenvironment and the correlation of LAP + CD4 + T cells with the progression of gastric tumor. Methods Forty gastric tumor patients and 20 healthy donors were enrolled in this study. The percentage of LAP+CD4+T cells in the peripheral blood and tumor tissue was detected by flow cytometry. The correlation of LAP+CD4+T cells with the progression of gastric tumor was analyzed. Results The percentage of LAP+CD4+T cells in the peripheral blood of gastric tumor patients was higher than that of health donors:(10.9±3.3)%vs. (4.3 ± 1.2)%;the percentage of LAP+CD4+T cells from tumor tissue was higher than that from non-tumor tissue:(13.5 ± 5.3)%vs. (4.7 ± 1.4)%. The percentage of LAP+CD4+T cells in peripheral blood from metastasis patients was higher than that from non-metastasis patients and health donors: (10.1 ± 6.4)% vs. (4.5 ± 1.3)% and (4.3 ± 1.2)%. Conclusions LAP+ CD4+ T cells accumulates in gastric carcinoma microenvironment and the percentage of LAP+CD4+T cells increases along with the progression of gastric tumor.

OBJECTIVETo observe the effect of the decomposition products of necrotic tissues from wounds on the serum levels of inflammation factors in comparison with endotoxin.

METHODSThirty adult New Zealand rabbits were randomly divided into 3 groups and received injections of saline, necrotic tissue homogenate or endotoxin. From each rabbit, blood samples (2 ml) were collected from the central artery of the ears at 0, 2, 6, 12, 24, 30, 36, 48, and 60 h after the injection for measurement of serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1) and IL-6.

RESULTSThe serum level of TNF-α, IL-1 and IL-6 in the rabbits increased 2-4 h after injection of the necrotic tissue homogenate and reached the peak level at 12 h, followed by a gradual reduction since 36 h. No obvious changes in the levels of the inflammatory factors were found in saline group (P<0.01). Compared with endotoxin, necrotic tissue homogenate resulted in an early increment (2-4 h vs 5-6 h) and significantly higher peak levels (at 30 h) of the inflammation factors (P<0.05). Curve fitting showed a distinct difference between necrotic tissue homogenate and endotoxin in their effect on the inflammatory factors.

CONCLUSIONThe necrotic tissue decomposition products contain toxic substances that possess a different toxicity profile from endotoxin, and their toxicity can be even stronger.

Objective:To evaluate the effect of esketamine on postoperative acute lung injury (ALI) in pediatric patients undergoing living donor liver transplantation.Methods:Sixty pediatric patients of either sex with biliary atresia, aged 0-36 months, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, with cardiac function grade I or Ⅱ, with Child-Pugh grade B or C, undergoing living donor liver transplantation, were divided into 2 groups ( n=30 each) using a computer-generated table of random numbers: control group (group C) and esketamine group (group S). Combined intravenous-inhalational anesthesia was performed with propofol and sevoflurane in both groups, and in addition esketamine was intravenously infused continuously after induction in group S. After anesthesia induction (T 0), at 60 min after start of surgery (T 1), at 10 min after anhepatic phase (T 2), at 60 min after portal vein opening (T 3), and immediately after abdominal closure (T 4), central venous blood samples were collected for determination of the serum concentrations of Clara cell secretory protein 16, surface active protein D, soluble receptor for advanced glycation end-products, high mobility group protein B1, interleukin-1beta and tumor necrosis factor-alpha (using enzyme-linked immunosorbent assay), concentrations of malondialdehyde (using TBA method), and activity of superoxide dismutase (using hydroxylamine method). The dynamic lung compliance was recorded from T 0 to T 4. Blood samples were taken from the radial artery at T 0 and 24 h after surgery (T 5) for blood gas analysis, and oxygenation index and respiratory index were calculated. Lung ultrasound scores were recorded at 24 h before surgery and T 5. The postoperative mechanical ventilation time and duration of intensive care unit stay were recorded. The occurrence of ALI within 7 days after liver transplantation was observed. Results:Compared with group C, the serum concentrations of Clara cell secretory protein 16, surface active protein D, soluble receptor for advanced glycation end products, high mobility group protein B1, interleukin-1beta, tumor necrosis factor-alpha and malondialdehyde were significantly decreased, and the activity of superoxide dismutase was increased at T 3, 4, the oxygenation index was increased and respiratory index was decreased at T 3-T 5, lung ultrasound C score and B score were decreased at T 5, the postoperative mechanical ventilation time and duration of intensive care unit stay were shortened, and the incidence of ALI was decreased in group S ( P<0.05). Conclusions:Esketamine can alleviate postoperative ALI in pediatric patients undergoing living donor liver transplantation.

Objective:To compare the effects of different anesthesia methods on perioperative lung injury in pediatric patients with biliary atresia undergoing living donor liver transplantation.Methods:Ninety-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ pediatric patients with biliary atresia, regardless of gender, aged 0-36 months, with cardiac function grade of Ⅰ or Ⅱ and Child-Pugh grade of B or C, undergoing elective living donor liver transplantation, were selected. According to the anesthesia method, the pediatric patients were divided into 3 groups: propofol-based anesthesia group (P group, n=30), sevoflurane-based anesthesia group (S group, n=30) and propofol-sevoflurane-based anesthesia group (PS group, n=31). Group P received intravenous infusion of 1% propofol 9-15 mg·kg -1·h -1. In group S, sevoflurane was inhaled and the end-tidal concentration was maintained at 2.6%-4.0%.In PS group, 1% propofol 9-15 mg·kg -1·h -1 was intravenously infused and sevoflurane was inhaled, maintaining an end-tidal concentration at 1.0%-2.5%. Remifentanil 0.1-1.0 μg·kg -1·min -1 was intravenously infused during operation for analgesia, and cisatracurium besylate 1-2 μg·kg -1·min -1 was intravenously infused to maintain muscle relaxation in three groups. Immediately after anesthesia induction (T 0), at 60 min after start of surgery (T 1), at 10 min of anhepatic phase (T 2), at 60 min after portal vein opening (T 3), and immediately after abdominal closure (T 4), the concentrations of serum Clara cell secretory protein 16 (CC16), surfactant protein (SP-D), soluble receptors for advanced glycation end products (s-RAGE), high mobility group protein B1 (HMGB1), tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) were measured using enzyme-linked immunosorbent assay method, and lung compliance (Cdyn) was simultaneously recorded. At T 0-T 4 and 24 h after surgery (T 5), the arterial blood gas analysis was performed to calculate the oxygenation index (OI) and respiratory index (RI). Lung ultrasound scores (LUS scores) were assessed at 24 h before surgery and T 5. The occurrence of pulmonary complications was recorded within 7 days after surgery. The survival was observed for 6 months after surgery. Results:There were no statistically significant differences in serum concentrations of CC16, SP-D and s-RAGE concentrations and LUS scores at different time points between group S and group P ( P>0.05). Compared with S group and P group, the serum CC16 concentrations at T 3 and s-RAGE concentrations at T 3, 4 were significantly decreased, and the C and B scores were decreased at T 5 in PS group ( P<0.05). There were no statistically significant differences in the concentrations of serum HMGB1, IL-1β and TNF-α, Cydn and incidence of ALI/ARDS, pulmonary infection, pleural effusion, and atelectasis within 7 days after surgery among the three groups( P>0.05). The 6-month survival rate was 100% in the three groups. Conclusions:Propofol-sevoflurane-based anesthesia has a better efficacy in reducing perioperative lung injury than propofol-based anesthesia and sevoflurane-based anesthesia in the perioperative period of liver transplantation.

OBJECTIVETo explore the influence of exogenous putrescine on the function of liver and apoptosis of liver cells in rats.

METHODSNinety healthy clean SD rats were divided into control group (C, n = 10, intraperitoneally injected with 2 mL normal saline), low dosage putrescine group (LP, n = 40), and high dosage putrescine group (HP, n = 40) according to the random number table. Rats in the latter two groups were intraperitoneally injected with approximately 2 mL putrescine (2.5 or 5.0 g/L) with the dosage of 25 or 50 µg/g. Ten rats from group C at post injection hour (PIH) 24 and 10 rats from each of the latter two groups at PIH 24, 48, 72, 96 were sacrificed. Heart blood was obtained for determination of serum contents of ALT and AST. Liver was harvested for gross observation and histomorphological observation with HE staining. Apoptosis was shown with in situ end labeling, and apoptosis index (AI) was calculated. Data among the three groups and those at different time points within one group were processed with one-way analysis of variance or Welch test; LSD or Dunnett's T3 test was used for paired comparison; factorial design analysis of variance of two factors was applied for data between group LP and group HP.

RESULTS(1) No obvious abnormality was observed at gross observation of liver of rats in each group. Liver tissue of rats in group C was normal. Light edema was observed occasionally in liver of rats in groups LP and HP, but necrotic cells were not seen. (2) Content of ALT at PIH 24, 48, 96 and content of AST at PIH 72 and 96 in group LP were respectively (38 ± 10), (45 ± 6), (34 ± 4), (207 ± 18), (196 ± 19) U/L, and content of ALT at PIH 72 and 96 and content of AST at PIH 24, 72, 96 in group HP were respectively (38 ± 6), (48 ± 5), (213 ± 43), (209 ± 40), (230 ± 29) U/L. They were significantly higher than those of rats in group C [(29 ± 5), (163 ± 42) U/L, with P values all below 0.01]. There were statistically significant differences between group LP and group HP in the content of ALT at PIH 48, 72, 96 and content of AST at PIH 96 (with P values all below 0.05). Compared with that at PIH 24 of each group, content of ALT of rats in group LP at PIH 48 and that of rats in group HP at PIH 96, as well as content of AST of rats in group LP at PIH 48, 72, 96 and that of rats in group HP at PIH 48 were significantly increased or decreased (with P values all below 0.05). Factorial analysis showed that the differences due to different concentration of putrescine on content of AST were statistically significant (F = 12.21, P = 0.001), but not on content of ALT (F = 0.01, P = 0.974) between group LP and group HP. (3) AI values of rats in group LP at PIH 24, 48, 72 were respectively (5.69 ± 0.38)%, (13.80 ± 1.66)%, (11.56 ± 1.74)%, and AI values of rats in group HP at PIH 72 and 96 were respectively (10.29 ± 1.43)%, (15.29 ± 1.41)%. They were all obviously higher than AI value of control group at PIH 24 [(3.50 ± 0.30)%, with P values all below 0.01]. There were statistically significant differences between group LP and group HP in AI value at PIH 24, 48, 96 (with P values all below 0.05). Compared with that at PIH 24 of each group, AI value of rats in groups LP and HP at PIH 48, 72, 96 were significantly increased or decreased (with P values all below 0.05). Factorial analysis showed that the differences in the influence of concentration of putrescine and stimulation time on AI value were statistically significant (with F values respectively 22.95 and 130.44, P values all below 0.01).

CONCLUSIONSIntraperitoneal injection of exogenous putrescine in the dosage of 25 or 50 µg/g could lead to certain degree of functional damage of liver and apoptosis of liver cells of rat. The higher the dosage and the longer the stimulation time, the more obvious the damage and apoptosis would be.
