ABSTRACT

OBJECTIVES@#To investigate the levels of fat-soluble vitamins A, D, and E in children with obesity and their influencing factors.@*METHODS@#A total of 273 children with obesity who attended the Department of Clinical Nutrition, Xi'an Children's Hospital, from January 2019 to April 2021 were enrolled as the obesity group. A total of 226 children with normal body weight who underwent physical examination during the same period were enrolled as the control group. Anthropometric parameters and body composition were measured for both groups, and the serum concentrations of vitamins A, D, and E were also measured.@*RESULTS@#Compared with the control group, the obesity group had significantly higher serum levels of vitamin A [(1.32±0.21) μmol/L vs (1.16±0.21) μmol/L, P<0.001] and vitamin E [(9.3±1.4) mg/L vs (8.3±1.2) mg/L, P<0.001] and a significant reduction in the level of 25-hydroxyvitamin D [(49±22) nmol/L vs (62±24) nmol/L, P<0.001]. In the obesity group, the prevalence rates of marginal vitamin A deficiency, vitamin D deficiency/insufficiency, and vitamin E insufficiency were 5.5% (15/273), 56.8% (155/273), and 4.0% (11/273), respectively. After adjustment for body mass index Z-score and waist-to-height ratio, serum vitamin A level was positively correlated with age (P<0.001), while vitamins E and 25-hydroxyvitamin D levels were negatively correlated with age in children with obesity (P<0.001). After adjustment for age, the serum levels of vitamin A, vitamin E and 25-hydroxyvitamin D were not correlated with degree of obesity, percentage of body fat, and duration of obesity in children with obesity, while the serum levels of vitamins A and E were positively correlated with waist-to-height ratio (P<0.001).@*CONCLUSIONS@#There are higher serum levels of vitamins A and E in children with obesity, especially in those with abdominal obesity, while serum vitamin D nutritional status is poor and worsens with age. Therefore, vitamin D nutritional status should be taken seriously for children with obesity, and vitamin D supplementation should be performed when necessary.

ABSTRACT

Objective: To investigate the gene expression characteristics of peripheral blood mononuclear cells from patients with high altitude pulmonary hypertension (HAPH) in Naxi residents living in Lijiang, Yunnan, and to explore the underlying pathogenesis and value for potential drug selection. Methods: This is a case-control study. Six patients with HPAH (HPAH group) and 4 normal subjects (control group) were selected from the Naxi residents who originally lived in Lijiang, Yunnan Province. The general clinical data of the two groups were collected, and the related indexes of pulmonary artery pressure were collected. Peripheral blood mononuclear cells of the subjects were collected for RNA sequencing. The differences on gene expression, regulatory network of transcription factors and drug similarity between the two groups were compared. The results were compared with the public data of idiopathic pulmonary arterial hypertension (IPAH). Biological processes and signal pathways were analyzed and compared between HPAH and IPAH patients. Results: The age of 6 patients with HAPH was (68.1±8.3) years old, and there were 2 males (2/6). The age of 4 subjects in the control group was (62.3±10.9) years old, and there were 2 males (2/4). Tricuspid regurgitation velocity, tricuspid pressure gradient and pulmonary systolic pressure in HAPH group were significantly higher than those in control group (all P<0.05). The results of RNA sequencing showed that compared with the control group, 174 genes were significantly upregulated and 169 genes were downregulated in peripheral blood mononuclear cells of HAPH group. These differentially expressed genes were associated with 220 biological processes, 52 molecular functions and 23 cell components. A total of 21 biological processes and 2 signal pathways differed between HPAH and IPAH groups, most of which were related to inflammation and immune response. ZNF384, SP1 and STAT3 were selected as highly correlated transcription factors by transcription factor prediction analysis. Trichostatin A and vorinostat were screened out as potential drugs for the treatment of HAPH by drug similarity analysis. Conclusions: There are significant differences in gene expression in peripheral blood monocytes between HAPH patients and normal population, and inflammation and immune dysfunction are the main pathogenic factors. Trichostatin A and Vorinostat are potential drugs for the treatment of HAPH.

ABSTRACT

In the era of artificial intelligence based on big data, data acquisition, storage and processing are more convenient, which provides a guarantee for accelerating the development of traditional Chinese medicine (TCM), but it has not yet achieved organic integration with TCM theory. Based on preliminary research on the supramolecular "Qi chromatography" theory of TCM, combined with the current development trend of artificial intelligence, this paper analyzed the biological intelligence attribute of the function of TCM supramolecular "imprinting template", in order to provide reference for the development of TCM drug innovation. Both the human body and Chinese materia medica are giant complex supramolecular bodies evolved from natural organisms. According to the "imprinting template", the "social molecules" are controlled step by step to form the meridians and viscera. The interaction produces the original theory of TCM, in which the self-recognition, self-assembly, self-organization and self-replication of the "imprinting template" reflect the "intelligence" function attributes:the human body uses the "imprinting template" to self-identify and sense the ingredients of TCM, and store the memory information database in the meridian and collateral organs in the form of "imprinting template", and then pass the "imprinting template". The comparison, analysis, and judgment of imprinting templates guide the self-assembly, self-organization and self-replication among "molecular society", synthesize biological machines, produce biological functions, repair or strengthen biological supramolecular bodies, and present the most basic "intelligence" attribute. This suggests that the theory of theory-method-prescription-medicine of TCM is the weak embodiment of biological "intelligence", while the human brain function is the strong embodiment of biological "intelligence". Since the intelligent function of supramolecular "imprinting template" runs through the natural world, artificial intelligence that can characterize the strong "intelligence" form of the human brain will also be integrated into all aspects of the natural world, suggesting the development direction of "intelligence" functionalization of drug innovation mode.

ABSTRACT

Exosomes are lipid bilayer membranous vesicles actively secreted by various cells in the organism, which are like nanoparticles and have messenger targeting. Combining with the theory of supramolecular "Qi chromatography" of traditional Chinese medicine (TCM), research ideas and strategies of modernization of TCM can be constructed. Exosomes are secreted by cells, and the membrane contains nucleic acids, proteins, lipids and small molecular metabolites and others, which can accurately coordinate the functions of each cell, concentrate and transmit the functional information of the parent cell, and is the concise form of reflecting cell functions. At the same time, it is loaded with the "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM. If the "imprinted templates" carrying rules among the gene-protein-lipid-small molecules wrapped in it is studied, the modern experimental research ideas and strategies of TCM theory can be established for revealing the functions of the body's meridians and viscera. Firstly, the present situation of exosomes, including discovery, secretion, characteristics, functions, attribution, uptake, research methods and application status, were reviewed in this paper. And the natural properties of its precise messenger targeted delivery vehicle were elaborated, reflecting the operation law of microscopic substances in meridians and viscera. Secondly, to explore it as an important carrier of the concentrated "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM, and integrating the research methods of exosomes and supramolecular chemistry of TCM, this paper proposes experimental research ideas and strategies on the microscopic material basis of meridians and viscera, compatibility of TCM compound, and targeting of TCM targeted preparations.

ABSTRACT

With the large use of vertebral augmentation in the treatment of osteoporotic thoracolumbar fracture (OTLF), the complication of cement leakage has become an increasing concern. Although most cement leakage has no obvious clinical symptoms, some patients still sustain serious complications such as vertebral fracture, pulmonary embolism and spinal nerve compression. Cement leakage is closely related to patients′ own factors, cement factors and perioperative related factors. To clarify the risk factors of cement leakage with implementation of preventive measures accordingly is of great guiding significance to improve the clinical efficacy and surgical safety. Therefore, the authors discuss bone cement leakage in aspects of the risk factors and preventive measures so as to provide a reference for reducing the incidence of cement leakage.

ABSTRACT

Objective:To investigate the effect of ketamine on dryness maintenance of breast cancer (BC) cells by regulating LncRNA PVT1/MYC axis.Methods:BC cell line MCF-7 was treated with different concentration of ketamine (0, 5, 10 or 20 g/ml) or treated with 20g/ml ketamine for different periods (0, 24, 48 or 72h) . Furthermore, the expression of METTL3, PVT1 and MYC in MCF-7 cells was interfered and MCF-7 cells were divided into different groups.Western blot was used to detect the expression levels of stem cell characteristic related molecules (OCT4 and SOX2) . The expression level of PVT1/MYC in each group was detected by qRT-PCR. MeRIP analysis was used to detect THE m6A methylation level of PVT1.Results:Ketamine treatment significantly reduced the number of BC globules and inhibited the protein expression of OCT4 and SOX2 in a dose-and time-dependent manner (all P<0.05) . Ketamine regulated m6A level of METTL3-mediated PVT1. Compared with ketamine+pcDNA3.1 group (207±11) , the number of globules formed in ketamine+PVT1 group (311±15) was significantly increased ( t=12.06, P<0.001) , and the protein expression levels of OCT4 and SOX2 were increased ( t=9.68, P<0.001; t=11.50, P<0.001) . MYC was a downstream regulatory gene of PVT1. Compared with ketamine+PVT1+ Si-NC group, ketamine+PVT1+si-MYC group significantly reduced the number of spheroid formation ( t=0.54, P=0.005) and the expression levels of OCT4 and SOX2 proteins ( t=5.98, P=0.004) ( t=7.33, P=0.002) . Conclusion:Ketamine mediates the expression of PVT1 and its downstream gene MYC by inhibiting THE m6A level of PVT1, thus inhibiting the stem cell-like characteristics of BC cells.

ABSTRACT

OBJECTIVE@#To explore the dynamic changes of lumbosacral sagittal parameters after real-time three-dimensional navigation assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and traditional open TLIF for treatment of lumbar degenerative disease.@*METHODS@#The clinical data of 61 patients with lumbar degenerative disease underwent single-segment surgery from September 2017 to September 2019 were retrospectively analyzed. Among them, 31 cases underwent MIS-TLIF with 3D navigation techniques (MIS-TLIF group) and another 30 cases underwent conventional open TLIF (traditional open TLIF group). The basic information, operative time and intraoperative blood loss were collected. The sagittal radiologic parameters were measured before surgery and 3 months after surgery, including lumbar lordosis (LL), segmental lordosis (SL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), anterior disc height (ADH), posterior disc height(PDH).And the average disc height(DH) and pelvic incidence to lumbar lordosis mismatch (PI-LL) were calculated.@*RESULTS@#Operative time and intraoperative blood loss in MIS-TLIF group were significantly less than in traditional open TLIF group(@*CONCLUSION@#Real-time navigation-assisted MIS-TLIF and traditional open TLIF can recover DH in a short term for lumbar degenerative diseases, improve LL and PI-LL, and make the arrangement of the sagittal plane of the lumbosacral region more coordinated after surgery. But only the navigation assisted MIS -TLIF can significantly improve SL. Compared with traditional open TLIF, real-time navigation assisted MIS-TLIF in the treatment of degenerative lumbar diseases has the advantages of short operation time and less intraoperative bleeding.

ABSTRACT

Under the guidance of the theory of traditional Chinese medicine (TCM), charcoal drugs are widely used in clinical treatment of various bleeding syndromes, in addition, they also have the effect in anti-diarrhea and anti-ulcer, but charcoal drugs are especially effective in stopping bleeding. According to the changes in the properties after processing, the hemostatic effect of charcoal drugs can be roughly divided into two categories. One is not used for hemostasis itself, but used for hemostasis after processing. The other is used for hemostasis itself, and the drug properties are changed or the hemostatic ability is enhanced after processing. By summarizing researches on historical evolution, processing mechanism and pharmacological effects of the commonly used hemostatic charcoal drugs, the author found that preservation or increase of active substances after processing was closely related to the hemostatic effect of charcoal drugs. The hemostatic mechanism mainly involves the influence of coagulation system and platelet function, etc. At the same time, combined with the theory of Qi chromatograph of TCM supramolecular, this paper puts forward the supramolecular research strategy on hemostatic mechanism of charcoal drugs, in order to provide reference for revealing the scientific connotation of charcoal drugs for hemostasis.

ABSTRACT

Objective:To construct the targeting evaluation method of traditional Chinese medicine (TCM) preparations based on supramolecular Qi chromatography theory, and to study the liver targeting effect of Bupleuri Radix on Pien Tze Huang. Method:The molecular connectivity index (MCI) was used to analyze the characteristics of imprinted template and liver targeting tendency of TCM mainly attributed to liver meridian and components of Pien Tze Huang, and combined with target dynamics and total statistical moment principle, aimed at the independent action characteristics of multi-component imprinted template of TCM, a method for evaluating the targeting of TCM preparations was established. Hepatoma rats in Pien Tze Huang group, Bupleuri Radix<italic> </italic>group, Pien Tze Huang+Bupleuri Radix group and blank group were tested and verified. Result:After the average value of MCI of TCM mainly attributed to liver meridian was deducted, the MCI similarity between Pien Tze Huang group and Bupleuri Radix group was 0.376 8, Pien Tze Huang+Bupleuri Radix group and Bupleuri Radix group was 0.988 2, so it was predicted that Bupleuri Radix could enhance the liver targeting of Pien Tze Huang. A system for evaluating the targeting of TCM compounds was established, including relative total uptake efficiency (RUE<sub>T</sub>), relative total concentration (RC<sub>T</sub>), relative imprinted tendency (RIT<sub>T</sub>) and relative imprinted variance (RIV<sub>T</sub>). The RUE<sub>T</sub> and RC<sub>T</sub> of liver were the highest in all tissues (RUE<sub>T</sub>=1.88>1,RC<sub>T</sub><italic>=</italic>2.30>1), and the corresponding values of other tissues were all <1, indicating that Pien Tze Huang combined with Bupleuri Radix could increase its distribution in liver and enhance liver targeting. Except for plasma, the RIT<sub>T</sub> and RIV<sub>T</sub> of other tissues fluctuated around 1.0, indicating that targeted modification did not change imprinted tendency of Pien Tze Huang and had no significant effect on the types of components. Conclusion:Under the guidance of supramolecular Qi chromatography theory, a targeting evaluation parameter system can be established to characterize the multi-component imprinted effect of TCM preparations by MCI and total statistical moment parameters, so as to realize the evaluation of targeting of TCM preparations. The addition of Bupleuri Radix can increase the liver targeting of Pien Tze Huang.

ABSTRACT

The application of modern scientific theories and technologies to explore the mechanism of Chinese medicine and its compounds is one of the key issues in realizing the modernization of traditional Chinese medicine (TCM) research. Chinese medicine and its compounds produce comprehensive pharmacodynamics through multiple components acting on multiple targets, the core of clarifying the mechanism is to solve the key scientific problems of static correlation and dynamic integration verification between the components and the target network topology. At present, the effective method to clarify the mechanism of Chinese medicine and its compounds is to statically correlate the topological network of in vitro components and targets through network pharmacology. Although there are also component-target verification studies, they often learn from research idea of single component-single target, it is urgent to establish a quantitative integration and overall verification method that conforms to the characteristics of TCM. According to supramolecular Qi chromatography theory of TCM, the microscopic mechanism of interaction between Chinese medicine and human body is actually the two supramolecular host and object groups (the active ingredient group of Chinese medicine and the target group of human body) based on imprinted template, which shows the macroscopic properties and pharmacodynamics. Based on this, the author proposes to use supramolecular Qi chromatography theory as the guidance, combined with supramolecular chemistry, network dynamics, quantitative pharmacology and other methods to quantitatively integrate and verify the compositions and the target groups with imprinted template as the core predicted by network pharmacology, looking for the optimal quality markers, greatly reducing the difficulty of multi-component-multi-target experimental verification of Chinese medicine and its compounds.

ABSTRACT

Objective: To analyse the clinical application of thoracodorsal artery perforator flaps (TDAPF) in the repair of head and neck defects. Methods: A retrospective review was conducted on 38 patients with oral and maxillofacial head and neck malignant tumors who underwent radical resection of oral and oropharyngeal carcinoma and TDAPF repair in the Department of Oral and Maxillofacial Head and Neck Oncology of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2017 to November 2018. Among them, 32 were males and 6 were females, aged 30-74 years. Flap size, vessel pedicle length, diameter and number of perforators, and flap fat thickness were recorded and counted. Elasti Meter and Skin Fibro Meter were applied to measure the skin elasticity and hardness in the donor areas of 4 kinds of skin flaps before the flap preparation. SPSS 19.0 statistical software was used for statistical analysis of the data. Results: All the flaps survived (100%). The mean elasticity of TDAPF [(41.2±12.9) N/m] was significantly lower than that of anterolateral thigh [(77.6±23.3) N/m, χ²=88.89, P<0.05], anterolateral thigh [(62.6±17.7) N/m, χ²=59.99, P<0.05] and or forearm flap [(51.7±8.6) N/m, χ²=37.82, P<0.05]. The hardness of TDAPF [(0.037±0.016) N] was also significantly lower than that of anterolateral femoral [(0.088±0.019) N, F=93.27, P<0.05], anteromedial femoral [(0.059±0.020) N, F=25.71, P<0.05] or forearm flap [(0.062±0.016) N, F=29.11, P<0.05]. Follow-up period ranged from 2 to 14 months. The 38 patients treated with TDAPF had a good recovery of the functions in the recipient areas, and the scars of the donor areas were not obvious after surgery, without serious complications. Conclusion: TDAPF is suitable for reconstruction of head and neck defect, with ductile texture and good recovery of the morphology and function of head and neck.

ABSTRACT

OBJECTIVE@#To evaluate the changes of heart structure and function in elite Chinese weightlifters by spot tracking technique.@*METHODS@#Chinese elite male weightlifters (weightlifter group, n=16) and age-matched healthy men (control group, n=16) were included as subjects. Transthoracic echocardiography and speckle-tracking automatic functional imaging were used for two-dimensional myocardial strain measurements.@*RESULTS@#The thickness of septum and left ventricular (LV) posterior wall and the myocardial mass index of LV were all higher than those of the control group [(9.3±1.3) mm vs. (8.0±0.4) mm, (9.2±0.8) mm vs. (8.0±0.8) mm, (77.8±12.8) g/m2 vs. (67.8±11.2) g/m2, all P < 0.05]. Although the LV ejection fraction (LVEF) and global long axis strain value (LVGLS) were not significantly different from those in the control group, the LV mean Sm and Em reflecting the systolic and diastolic functions of the LV were lower than those in the control group (P < 0.05). Further myocardial strain analysis showed that the absolute value of the long axial strain of the basal anteroseptal and mid-inferoseptal segments of the weightlifters were significantly lower than those of the control group [|(-15.1±4.2)%|vs.|(-18.7±3.0)%|, |(-18.8±2.6)%|vs.|(-21.3±2.8)%|, all P < 0.05]. There was no significant difference in other segments. The athletes were divided into two groups according to their best performance in the National Youth Games. The athletes were divided into two sub-groups according to their performance in the National Youth Games. The thickness of the septum in the sub-group with better performance (who ranked the 1st to 8th) was larger [(10.2±1.1) mm vs. (8.5±1.0) mm, P < 0.05], and the absolute value of the long-axis strain in the mid-inferoseptal segment was lower [|(-17.1±2.1)%|vs.|(-20.4±2.1)%|, P < 0.05].@*CONCLUSION@#The thickening of septum is more obvious in the excellent weightlifters, accompanied by the decrease of myocardial systolic function. The speckle-tracking technique of echocardiography can identify the changes of the heart structure and function of elite athletes at an early stage, which may provide a basis for sports medicine supervision and the selection of excellent talents.

ABSTRACT

OBJECTIVE@#To investigate the effect and involved mechanism of RSL3 on ferroptosis action in acute leukemia cells MOLM13 and its drug-resistant cells.@*METHODS@#After MOLM13 treated with RSL3, CCK-8 assay was performed to detect cell viability, flow cytometry was used to detect the reactive oxygen species (ROS) level of the cells, RT-qPCR and Western blot were used to detect the expression of glutathione peroxidase 4 (GPX4). After MOLM13/IDA and MOLM13/Ara-C, the drug-resistant cell lines were constructed, the ferroptosis induced by RSL3 was observed. Bone marrow samples were collected from patients with acute monocytic leukemia. RT-qPCR and Western blot were performed to detect the expression of related genes and proteins involved in ferroptosis pathway.@*RESULTS@#RSL3 significantly inhibited the cell viability of MOLM13 and increased the intracellular ROS level, which were partially reversed by ferrostatin-1. The mRNA and protein expression of GPX4 decreased in MOLM13 treated with RSL3. RSL3 inhibited the viability of MOLM13/IDA and MOLM13/Ara-C cells more strongly than that of non-drug resistant cells, also increased the intracellular ROS level . The cytotoxic effects were partially reversed by ferrostatin-1. The mRNA and protein expressions of GPX4 in MOLM13/IDA and MOLM13/Ara-C cells were higher than those in non-drug resistant cells. The mRNA and protein levels of GPX4 in bone marrow of relapsed/refractory acute mononuclear leukemia patients were higher than those of ordinary acute mononuclear leukemia patients.@*CONCLUSION@#RSL3 can induce non-drug resistant cells MOLM13 ferroptosis by inhibiting GPX4 activity. MOLM13/IDA and MOLM13/Ara-C are more sensitive to RSL3 compared with non-drug resistant cells MOLM13, which may be caused by the differences in GPX4 expression. The expressions of GPX4 mRNA and protein in relapsed/refractory acute mononuclear leukemia are higher than those in ordinary acute mononuclear leukemia.

ABSTRACT

Cardiac hypertrophy is a common pathological process of various cardiovascular diseases and eventually develops into heart failure. This paper was aimed to study the different pathological characteristics exhibited by different mouse strains after hypertrophy stimulation. Two mouse strains, A/J and FVB/nJ, were treated with isoproterenol (ISO) by osmotic pump to induce cardiac hypertrophy. Echocardiography was performed to monitor heart morphology and function. Mitochondria were isolated from hearts in each group, and oxidative phosphorylation function was assayed in vitro. The results showed that both strains showed a compensatory enhancement of heart contractile function after 1-week ISO treatment. The A/J mice, but not the FVB/nJ mice, developed significant cardiac hypertrophy after 3-week ISO treatment as evidenced by increases in left ventricular posterior wall thickness, heart weight/body weight ratio, cross sectional area of cardiomyocytes and cardiac hypertrophic markers. Interestingly, the heart from A/J mice contained higher mitochondrial DNA copy number compared with that from FVB/nJ mice. Functionally, the mitochondria from A/J mice displayed faster O

ABSTRACT

The present work is to analyze the HPLC fingerprints of mulberry-sourced materials(Mori Ramulus, Mori Folium, Muri Cortex, Mori Fructus) using the fingerprint division total statistical moment method and information entropy, and to study the diffe-rences of the chemical components and the overall characteristics of the imprinting template in different parts of mulberry-sourced medicinal materials, so as to provide the basis for finding the effective substances in response to "homologous and different effect" of mulberry(Morus alba). The fingerprints of 24 batches of mulberry-related materials, such as Mori Ramulus, Mori Folium, Muri Cortex, Mori Fructus, were established, and the similarities and differences of the fingerprints were analyzed by calculating the division total statistical moment parameters and information entropy. The AUC_T, MCRT_T, VCRT_T and H values of 24 batches of mulberry-sourced materials were less than 0.05, with significant difference. Among them, all samples showed absorption peaks within 3-11, and 20-24 min, indicating that the four types had the identical or similar chemical composition in the same time period. After 34 min, none of the four types showed absorption peaks. Greater VCRT_T value of the fingerprints of the four kinds was observed at the retention time ranges of 3-4, 16-18, 25-27, and 31-32 min, indicating that the components of the four kinds were significantly different in these time periods; and VCRT_T value of the mulberry was significantly higher than that of the other three kinds of medicinal materials at the retention time windows of 3-4 and 15-17 min; the VCRT_T value of the mulberry white skin was significantly higher at the time windows of 8-10 and 28-30 min; the VCRT_T value of all four kinds was significantly higher within 21-23 min, indicating that the four herbs contain the same or similar components in the chromatogram during this period, but there may be significant differences between the content and the proportion. In addition, the information entropy of mulberry branches is the largest at 7-12, 23-27 min, and that of mulberry fruits is the largest at 2-8 min, which indicates that the components of mulberry branches and mulberry fruits respond greatly in the corresponding period of time, which is also the main peak period of their chemical components. For the chemical components and corresponding efficacy here. The results showed that there are significant differences in the components and contents of mulberry-sourced medicinal materials. The division total statistical moment and information entropy of the total amount of segments can be used to analyze the differences in the components of "homology and different effects", which could provide a more comprehensive analysis method for the determination of quality markers.
