OBJECTIVE To investigate the mechanism of the inhibitory effect of total flavonoids from Taraxacum mongolicum on high-fat diet-induced obesity in mice through modulation of intestinal flora. METHODS Twenty-four C57BL/6J mice were randomly divided into blank group, model group and T. mongolicum total flavonoid group, with 8 mice in each group. Except for the blank group, the other 2 groups were given a high-fat diet, while T. mongolicum total flavonoid group was given T. mongolicum total flavonoid [400 mg/(kg·d)] intragastrically, once a day, for 8 consecutive weeks. During the experiment, the food intake of each group of mice was recorded. After the last medication, the body mass, fat weight, blood lipid level and pathological changes of liver and epididymal fat in mice were evaluated to observe the effect of T. mongolicum total flavonoid on the treatment of obesity in mice. The changes in abundance and structure of intestinal flora in mice were detected by amplicon sequencing; the effects of T. mongolicum total flavonoids on fat metabolism related genes were analyzed by qPCR. RESULTS Compared with model group, the body weight of mice in T. mongolicum total flavonoids group was decreased significantly (P<0.05); the levels of total lipid cholesterol, triglycerides, and LDL cholesterol were all decreased significantly (P<0.01), and the level of HDL cholesterol was increased significantly (P<0.01); the fat indexes of inguinal white adipose tissue and epididymal white wind_lz@hactcm.edu.cn adipose tissue were significantly reduced (P<0.05); significant improvement in hepatocellular steatosis and adipose cytopathy were significantly improved; mRNA expressions of COX7A1 and COX8B were significantly upregulated (P<0.05). The results of bacterial colony detection showed that compared with the model group, there was a rising trend in the diversity of the bacterial colony in T. mongolicum total flavonoids group, and the Sobs index characterization and β diversity were increased significantly (P<0.05). Relative abundances of Blautia, norank_f_Ruminococcaceae, Bilophila, Alistipes, classified_f_Ruminococcaceae, Parabacteroides, norank_f_Desulfovibrionaceae, Anaerotruncus were significantly up-regulated(P<0.05), while those of Faecalibaculum, Erysipelatoclostridium, GCA-900066575, Tuzzerella, Lactobacillus, norank_f_norank_o_RF39, achnospiraceae_FCS020_group were significantly down-regulated (P<0.05). CONCLUSIONS T. mongolicum total flavonoids can reduce body mass, fat weight and blood lipid levels, and repair the pathological damage to liver and epididymal fat in obese mice, which is related to improving intestinal flora disorders caused by high-fat diet.

ObjectiveA multiplex amplification system was constructed based on the capillary electrophoresis platform for simultaneous detection of saliva, semen, and vaginal secretions using tissue-specific RNA markers. The aim of this study is to identify the tissue origin of suspicious body fluid stains found at crime scenes and determine whether the body fluid stains at the crime scene are one or several types among saliva, semen, and vaginal secretions. MethodsThirty saliva samples, forty semen samples, and forty vaginal secretion samples (half from 2015 and half from 2024) were collected from healthy adult volunteers. Through primer designing, system formulation, and PCR condition optimization, a multiplex fluorescent amplification system was constructed. The specificity, sensitivity, and detection ability for mixed samples of this system were investigated, and it was tested using real crime scene materials. In the primer design stage, to reduce the requirements for RNA template quality, the amplification products were set within 80-300 bp. In the system formulation stage, dominant and subordinate primers were mainly considered. By reducing the concentration of dominant primers and increasing that of subordinate primers, a capillary electrophoresis spectrum with an appropriate peak height ratio was finally obtained. Additionally, gradient experiments were designed to adjust the concentrations of PCR reagents and PCR amplification conditions, and multiple versions of DNA amplification enzymes were optimized to achieve the best experimental results. ResultsThrough statistical analysis, there was no significant difference in the capillary electrophoresis of the 3 types of body fluid samples from the two years (2015 and 2024), demonstrating that the sample preservation method in this study can preserve samples for a relatively long time. The composite amplification system constructed in this study exhibited high specificity for all 3 types of body fluid, with no cross-reactions between the markers of each type of body fluid. The minimum detection thresholds for the 3 types of body fluid reached 0.002 9, 0.001 5, and 0.42 mg/L, respectively. This system also had a high degree of discrimination for mixed samples, especially for semen-saliva mixtures, where each body fluid marker could still be successfully detected when the concentration ratio of semen to saliva was 100:1. Meanwhile, in the two actual cases presented in this article, the application of this composite amplification system performed outstandingly. ConclusionThe composite amplification detection system constructed in this study can achieve the correct screening of saliva, semen, and vaginal secretions, overcoming the problems such as low specificity and sensitivity of marker tests and unbalanced RFU values of each marker in previous studies. The specificity and sensitivity meet the practical work requirements, and the operation is simple. It provides an analytical and identification method for body fluid stains in actual case and is applicable to the identification of the tissue origin of biological evidence at crime scenes involving sexual assault, indecent assault, and other criminal acts. In the future, more types of body fluid markers will be screened to expand the types of body fluids detected by the system, and body fluid-specific cSNP and cInDel genetic markers will be introduced to infer the sources (individuals and types) of mixed and complex stains more accurately.

Objective To assess the nutritional status in elderly patients with chronic renal insufficiency (CRI) and reveal the key factors affecting the nutritional status. Methods A total of 310 elderly patients with CRI who received hospitalization treatment and outpatient follow-up in the hospital from January 2021 to June 2024 were selected as the investigation subjects. The nutritional status of patients was evaluated by mini-nutritional assessment (MNA) questionnaire, and the nutritional status and dietary structure of patients were comprehensively evaluated by anthropometric indicators [height, weight, body mass index (BMI), upper arm circumference, calf circumference], biochemical indicators [serum albumin (ALB), prealbumin (PA), hemoglobin (Hb), transferrin (TF)] and 24-hour dietary review method. According to the investigation results of nutritional status, the patients were divided into good nutrition group (MNA score≥24 points), nutritional risk group (MNA score of 17-23.5 points) and malnutrition group (MNA score<17 points). Univariate analysis was adopted to screen the potential influencing factors of elderly CRI. Multivariate logistic regression model was applied to analyze the influencing factors of malnutrition in elderly CRI patients. Results Among the 325 questionnaires were distributed, but only 310 valid questionnaires were recovered, with an effective recovery rate of 95.38%. Investigation results revealed that among the 310 patients, 29.35% (91 cases) had good nutritional status, and 42.26% (131 cases) had nutritional risk, and 28.39% (88 cases) had malnutrition. Univariate analysis indicated that there were statistical differences in BMI, CRI staging, serum ALB, PA, Hb, TF, protein intake and total calorie intake among the good nutrition group, the nutritional risk group and the malnutrition group (P<0.05). Multivariate logistic regression analysis suggested that low BMI (OR=0.903, 95%CI: 0.867-0.941), high CRI stage (OR=1.091, 95%CI: 1.053-1.130), low serum ALB (OR=0.907, 95%CI: 0.867-0.948), PA (OR=0.918, 95%CI: 0.888-0.949), Hb (OR=0.944, 95%CI: 0.909-0.997), TF (OR=0.912, 95%CI: 0.874-0.952), insufficient protein intake (OR=0.924, 95%CI: 0.882-0.969) and insufficient total calorie intake (OR=0.938, 95%CI: 0.909-0.968) were influencing factors for malnutrition in elderly patients with CRI (all P<0.05). Drawing ROC curve of malnutrition in elderly patients with CRI according to the prediction probability of logistic regression model found that the AUC, sensitivity, specificity, 95%CI and Youden index were 0.976, 93.18%, 92.34%, 0.953-0.990 (P<0.05) and 0.855. Conclusion The incidence rate of malnutrition is high in elderly patients with CRI, and is mainly affected by factors such as low BMI, high CRI stage, low serum ALB, PA, Hb and TF levels and insufficient protein and total calorie intakes. In addition, logistic regression model has high predictive value and can provide a reference for early clinical identification of high-risk population with malnutrition among elderly patients with CRI.

ObjectiveTo observe the distribution of traditional Chinese medicine (TCM) syndrome types in advanced pancreatic cancer patients, and explore the association between median survival time and different TCM syndromes and different intervention times of Chinese herbal medicine (CHM). MethodsThe clinical data of 136 advanced pancreatic cancer patients who have received CHM for more than 3 months were collected retrospectively, including gender, age, family history, smoking history, drinking history, location of disease, lymph node metastasis, multiple distant metastasis, western medicine treatment methods, TCM diagnosis and treatment information, and survival time. The Kaplan-Meier (KM) estimator was used, and the median survival time of patients was calculated. The TCM syndrome type of each patient was judged, and the main single syndrome types and compound syndrome types were summarized. The median survival time was compared among different compound syndrome types. The patients were further divided into the group of those having received CHM ≥6 months and those having received CHM <6 months. Whether receiving CHM ≥6 months was taken as the grouping variable, while the matching variables were age, gender, family history, smoking history, drinking history, location of disease, lymph node metastasis, multiple distant metastasis, surgery, chemotherapy, and radiotherapy when propensity score matching was performed, and the difference in median survival time between the two groups of patients before and after matching was compared. ResultsFor 136 cases of advanced pancreatic cancer, the top five single syndromes were spleen qi deficiency, liver blood stasis, liver qi stagnation, spleen dampness, and liver heat. The main compound types were liver constraint, spleen deficiency and blood stasis syndrome, liver-gallbladder damp-heat and blood stasis syndrome, liver constraint, qi stagnation and spleen deficiency syndrome, spleen-stomach yang deficiency and blood stasis syndrome, and spleen deficiency and dampness-heat internal accumulation syndrome. The overall median survival time before and after matching was 12.47 (7.70,17.10) months and 13.77 (8.83,17.20) months, respectively, and was significantly higher in the group treated with CHM ≥ 6 months than that treated with CHM <6 months (P<0.05). Among the 136 patients before matching, the median survival time of patients with spleen deficiency and dampness-heat internal accumulation syndrome was longest [16.23 (14.17,19.40) months], while that of patients with spleen-stomach yang deficiency and blood stasis syndrome was the shortest [7.33 (5.80,12.83) months]. For patients with liver constraint, spleen deficiency and blood stasis syndrome, liver-gallbladder damp-heat and blood stasis syndrome, and spleen-stomach yang deficiency and blood stasis syndrome, those having received CHM ≥ 6 months have much longer median survival time than those having received CHM <6 months (P<0.05). Among the 108 patients after matching, the median survival time of those with spleen deficiency and dampness-heat internal accumulation syndrome was the longest [15.23 (7.67,18.27) months], while that of spleen-stomach yang deficiency and blood stasis syndrome was the shortest [8.80 (6.90,16.17) months]. For patients with liver-gallbladder dampness-heat and blood stasis syndrome and spleen-stomach yang deficiency and blood stasis syndrome, the median survival time was higher in the group treated with CHM ≥ 6 months treated with CHM <6 months (P<0.05). ConclusionAfter treatment with CHM, advanced pancreatic cancer patients with spleen deficiency and damp-heat internal accumulation had a better prognosis, while those with spleen-stomach yang deficiency and blood stasis had a worse prognosis. Treatment with CHM ≥ 6 months could extend the median survival of advanced pancreatic cancer patients with liver-gallbladder damp-heat and blood stasis syndrome and spleen-stomach yang deficiency and blood stasis syndrome.

According to the theory of qi channels, we explored the relationship of the method of invigorating blood and regulating tumour immunity, to provide ideas and methods for traditional Chinese medicine for regulating tumour immunity and anti-tumour metastasis. It is believed that qi channels are closely related to tumour immunity, and qi channels are equivalent to immune networks such as immune cells and immune factors with anti-tumour immunity in the tumour immune micro-environment. Combined with the physiological function and pathological characteristics of qi channels, it is proposed that the pathogenesis of qi channels-related disease due to qi channels failing to govern, blood stasis obstructing, and qi channels deficiency and stagnation as the basis for the occurrence of tumour immunosuppression and metastasis, and that qi channels constraint and stagnation as the condition for the occurrence of tumour immunosuppression and metastasis. In view of the pathomechanism of tumour immune escape caused by qi channels failing to govern, it is proposed that the therapeutic principle of regulating qi and channels to regulate tumour immunity by invigorating blood circulation method could be "performing functions when there is free flow, reaching the expectation when balanced", and the key of treatment is to regulate qi and channels, unblock the collaterals to dispel stasis.

OBJECTIVE To explore the material basis of the anti-inflammatory effect of the petroleum ether extract from Melastoma dodecandrum by establishing its fingerprint and combining it with cellular pharmacodynamics experiments. METHODS HPLC method was adopted; the fingerprints of 20 batches of petroleum ether extract from M. dodecandrum were drawn using The Similarity Evaluation System of TCM Chromatographic Fingerprint (2012 edition); similarity evaluation and common peak identification were carried out. The lipopolysaccharide-induced inflammation model of mice mononuclear macrophages (RAW264.7) was established; the inhibitory rates of nitric oxide (NO) and tumor necrosis factor α (TNF-α) were used as indexes to investigate the anti-inflammatory activity of the petroleum ether extract from M. dodecandrum; grey correlation degree method and partial least square regression analysis were adopted to study the spectrum-effect relationship. Molecular docking was used to validate the binding activity of the anti-inflammatory active ingredients with TNF-α and iNOS protein receptor. RESULTS There were 19 common peaks in the fingerprint of the petroleum ether extract from M. dodecandrum, the similarity of 20 batches of samples ranged from 0.603-0.990, and five components were identified, such as vitexin (peak 5), isovitexin (peak 6), ellagic acid (peak 7), quercetin (peak 9) and luteolin (peak 10). The grey correlation degree between 19 common peaks of the petroleum ether extract from M. dodecandrum and the inhibition rates of NO and TNF-α were all greater than 0.7; peaks 19, 13, 9 (quercetin), 12, 5 (vitexin), 6 (isovitexin), 8, 7 (ellagic acid), 18, 1 were positively correlated with NO inhibition rate, and peaks 8, 10 (luteolin), 13, 15, 3, 19, 17, 7 (ellagic acid), 18, 1 were positively correlated with inhibition rate of TNF-α. The binding energies of vitexin, isovitexin and quercetin with iNOS protein receptor were less than -5.0 kcal/mol. CONCLUSIONS Vitexin, isovitexin and quercetin may be the basis of the anti-inflammatory effect of the petroleum ether extract from M.dodecandrum.
