ABSTRACT

italic>γ-Aminobutyric acid (GABA) is a crucial inhibitory neurotransmitter found in various cells in the human body. While the GABAergic system is typically associated with the nervous system, recent research has revealed that immune cells and tumor cells also express components of this system. In the tumor microenvironment (TME), GABA is secreted to act extracellularly on other cells. GABA is metabolized via the GABA shunt and is involved in the tricarboxylic acid (TCA) cycle by generating succinate, which can provide energy for tumor cells. Activation of GABA receptors (GABARs) is a major pathway through which GABA participates in the regulation of antitumor immune responses. The activation of GABA type A receptors (GABAARs) can inhibit the activation and proliferation of T cells, elicit anti-inflammatory macrophages, and promote tumor cell growth and migration, while activation of GABA type B receptors (GABABRs) is generally considered to inhibit cancer cell migration and induce cancer cell apoptosis. In general, receptor activation inhibits immune cells, but the effect on tumor cells varies. Additionally, the downregulation of the expression levels of GABA transporters (GATs) is involved in tumor progression. Although antagonists of GABA metabolism and drugs that act on GABA receptors are considered therapeutic drugs for tumors, there have been few clinical studies conducted on them.

ABSTRACT

Objective: To analyze the association between exposure patterns of adverse childhood experiences (ACEs) and anxiety symptom trajectories in medical college students. Methods: A survey was conducted on first-year students from Anhui Medical College and Anqing Medical College, using the Childhood Abuse Questionnaire, Family Disability Questionnaire, Childhood Adverse Social Experience Item, and Anxiety Self Rating Scale. The baseline survey was conducted from November to December 2019, and two follow-up visits were conducted once every six months until November to December 2020. The latent class analysis (LCA) was used to analyze the exposure patterns of ACEs. The latent class growth analysis (LCGA) was used to analyze the development trajectory of anxiety symptoms. The multiple logistic regression model was used to analyze the correlation between different exposure patterns of ACEs and the trajectory of anxiety symptom trajectories. Results: A total of 3 662 college students aged (19.2±1.0) were surveyed. The LCA showed that the exposure patterns of ACEs could be divided into the "high ACEs" group (13.4%), "high neglect/emotional abuse" group (25.7%), "high family dysfunction" group (6.9%), "high neglect" group (27.1%), and "low ACEs" group (26.3%). The LCGA divided anxiety trajectories into four groups: "high anxiety decline" (7.1%),"anxiety increase "(4.1%), "moderate anxiety"(52.9%), and "low anxiety"(35.9%). Using the low ACEs group as a reference group, compared with the low anxiety trajectory, the high ACEs group, high neglect/emotional abuse group, high family dysfunction group, high neglect group, and medium to high-level anxiety trajectory were all associated with an increased risk (P<0.05). Conclusion: There is heterogeneity in ACEs exposure patterns among medical college students, and ACEs exposure patterns are important influencing factors for anxiety symptom trajectories.

ABSTRACT

Objective: To comprehensively evaluate the physical health level of students of different school-age segments in four regions of Anhui province using the entropy weight approximation ideal solution ranking method (TOPSIS), and to provide a scientific method and basis for conducting school health work evaluation. Methods: Using the physical fitness survey data of four regions in Anhui province, the entropy weight method was used to draw the weights of various indicators for different school-age segments of men and women. Then, the TOPSIS method was used to evaluate the school-age segments of men and women in the four regions. Finally, the physical health level of students in four regions was classified according to the results of entropy weight TOPSIS and the rank sum ratio method. Results: A total of 10 127 students were included in this study, with an average age of (11.85±3.82) years, including 5 050 males (49.8%) and 5 072 urban students (50.1%). The results of the entropy weight method showed that the weight of body mass index of boys was similar to that of girls in each school-age segment. According to the TOPSIS and rank sum ratio analysis, the physical health level of students in the four regions of Anhui province was different. The physical health score of Suzhou was 0.617 4 points, which was classified as the best grade. The scores of Hefei and Wuhu were 0.556 3 and 0.411 2, which were classified as middle. Jiju City scored 0.381 9 points, which was classified as poor. Conclusion: TOPSIS combined with rank sum ratio can reflect the level of students' physical health, which can be applied to the evaluation of students' physical health and provide a basis for monitoring students' physical health .

ABSTRACT

Under the guidance of the traditional Chinese medicine(TCM) theory of "Zangfu-organs of spleen and stomach" and the modern theory of "microbiota-gut-brain axis", this study explored the effects of Nardostachys jatamansi on the gut microbiota of rats with Parkinson's disease(PD). The 40 SD rats were randomly divided into the control group, PD model group, levodopa group, and Nardostachys jatamansi ethanol extract group. The PD model was established by subcutaneous injection of rotenone in the neck and back area. After 14 days of intragastric administration, the PD rats' behaviors were analyzed through open field test, inclined plane test, and pole test. After the behavioral tests, the striatum, colon, and colon contents of rats in each group were collected. Western blot was employed to detect the protein expression of tyrosine hydroxylase(TH) and α-synuclein(α-syn) in striatum and that of α-syn in colon. Enzyme linked immunosorbent assay(ELISA) was used to detect the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and nuclear factor-kappa B(NF-κB) in striatum and colon. High-throughput sequencing of 16 S rRNA gene was conducted to detect the differences in microbial diversity, abundance, differential phyla, and dominant bacteria of rats between groups. The results indicated that Nar. ethanol extract could relieve dyskinesia, reverse the increased levels of α-syn, TNF-α, IL-1β, and NF-κB in striatum, and improve the protein expression of TH in striatum of PD rats. The α diversity analysis indicated a significant decrease in diversity and abundance of gut microbiota in the PD model. The results of linear discriminant analysis effect size(LEfSe) of dominant bacteria indicated that Nardostachys jatamansi ethanol extract increased the relative abundance of Clotridiaceae, Lachnospiraceae, and Anaerostipes, and reversed the increased relative abundance of Proteobacteria, Gammaproteobacteria, Enterobacteriaceae, and Escherichia-Shigella in PD model group to exhibit the neuroprotective effect. In summary, the results indicated that Nar. ethanol extract exert the therapeutic effect on PD rats. Specifically, the extract may regulate gut microbiota, decrease the levels of proinflammatory cytokines, and reduce the protein aggregation of α-syn in the colon and striatum to alleviate intestinal inflammation and neuroinflammation. This study provides a basis for combining the theory of "Zangfu-organs of spleen and stomach" with the theory of "microbiota-gut-brain axis" to treat PD.

ABSTRACT

Objective: To assess the incidence of symptomatic torus tubarius hypertrophy (TTH) in recurred OSA in children, and to explore the preliminary experience of partial resection of TTH assisted with radiofrequency ablation. Methods: From January 2004 to February 2020, 4 922 children, who diagnosed as OSA and received adenotonsillectomy at the Department of Otolaryngology, The 4th Medical Center of the PLA General Hospital, were retrospectively reviewed. There were 3 266 males and 1 656 females, the age ranged from 1 to 14 years old(median age of 5.0 years). Twenty-two cases were identified with recurrence of OSA syndrome, and the clinical data, including sex, age of primary operation, age of recurrence and presentation, and opertation methods were analyzed. Follow-up was carried out by outpatient visit or telephone. Graphpad prism 5.0 software was used for statistical analysis. Results: Twenty-two cases were identified as recurred OSA and received revised surgery in 4 922 cases. Among these 22 cases, 11 cases were diagnosed as TTH resulting in an incidence of 2.23‰(11/4 922), 1 case was cicatricial adhesion on tubal torus (0.20‰, 1/4 922), 10 cases were residual adenoid combined with tubal tonsil hypertrophy (2.03‰, 10/4 922). Median age of primary operation was 3.0 years (range:2.4 to 6.0 years) in 11 TTH cases. Recurrent interval varied from 2 months to 5.5 years (2.4±1.9 years) after first operation. Age of revised partial resection of TTH was 7.0±2.7 years (range: 4.0 to 12.0 years). Average time interval between primary operation and revised operation was 3.5±2.1 years (range: 0.5 to 6.0 years). Individualized treatments were carried out based on partial resection of TTH assisted with radiofrequency ablation. All of 11 cases received satisfied therapeutic results without nasopharyngeal stenosis occured. Twenty-two cases were followed up for 1.6 to 13 years (median follow-up time was 6.2 years). Conclusions: TTH contributed to recurred OSA in child. TTH might be misdiagnosed as tubal tonsil hypertrophy. Partial resection of TTH assisted with radiofrequency ablation was a safty and effective treatment.

ABSTRACT

As an essential amino acid, tryptophan (Trp) has various physiological functions and is of great significance in the metabolic process of tumors. In the human body, tryptophan is mainly transformed through kynurenine metabolic pathway, which not only promotes the inherent malignant properties of tumor cells, but also leads to immune-suppressive tumor microenvironment. Changes in tryptophan metabolism often occur in tumors, accompanied by abnormal gene expression of tryptophan-related enzymes, among which indoleamine 2,3-bioxygenase (IDO)-related gene expression and tryptophan 2,3-dioxygenase (TDO)-related gene changes are the most significant. A large number of clinical trials on IDO inhibitors, TDO inhibitors and combination therapy have been carried out. This paper reviewed the tryptophan metabolic pathway, regulation of IDO (TDO), kynurenine (KYN) and other related genes in tumor cells, and outlined the development of therapeutic schedule targeting tryptophan-related genes. The new progress provides new ideas for the further exploration of tumor treatment options.

ABSTRACT

Tumor cells leads to enhanced glucose uptake and the conversion of a larger fraction of pyruvate into lactate even under the circumstance of abundant oxygen. This phenomenon of aerobic glycolysis is known as the Warburg effect. Lactic acid, as an important tool for tumor cells to modify the tumor microenvironment, promotes the process of tumor invasion and metastasis, and contributes to tumor development by inducing and recruiting immunosuppression-related cells and molecules. Lactic acid could efflux out of the cancer cells via the monocarboxylate transporters to prevent intracellular acidification. Lactate can inhibit the cytolytic activity of T cells and natural killer (NK) cells, promoting the differentiation of tolerogenic interleukin 10 (IL-10)-producing dendritic cells. Moreover, the lactate-derived lactylation of histone lysine residues can promote macrophage polarization toward the M2-like phenotype, suppressing the immune response within the tumor microenvironment. In this review, we discuss the role of lactate as an immunosuppressor molecule that contributes to tumor evasion from the aspects of lactic acid metabolism and its effect on immune cells. And we explore the possibility of targeting potential targets in lactate metabolism for tumor treatment. At last, we proposed a tumor immunotherapy strategy by inhibiting the pathway of aerobic glycolysis and proteins associated with the production and transport of lactic acid.

ABSTRACT

This paper aims to investigate the active components and mechanism of Valerianae Jatamansi Rhizoma et Radix against post-traumatic stress disorder(PTSD) based on network pharmacology and molecular docking. The main components and targets of Valerianae Jatamansi Rhizoma et Radix were obtained by literature mining methods, SwissTargetPrediction, BATMAN and ETCM database. PTSD-related genes were collected from DrugBank, TTD and CTD databases. The protein-protein interaction(PPI) network was constructed based on STRING, and the core targets of Valerianae Jatamansi Rhizoma et Radix in the treatment of PTSD were selected according to the topological parameters. Cytoscape 3.7.2 was used to construct the compound-target network. DAVID database was used for GO enrichment analysis and KEGG enrichment analysis. The relationship network of "compound-target-pathway" was constructed through Cytoscape 3.7.2 to analyze and obtain the key targets and their corresponding components in the network, and their results were verified by molecular docking. The results showed that a total of 47 components(such as valeraldehyde, dihydrovalerin, valerate, chlorovaltrate K, 8-hydroxypinoresinol, 6-hydroxyluteolin, apigenin, farnesin, vanillin, luteolin, kaempferol, glycosmisic acid and pogostemon) of Valerianae Jatamansi Rhizoma et Radix may act on 94 key targets such as CNR1, MAOA, NR3 C1, MAPK14, MAPK8, HTR2 C and DRD2. Totally 29 GO terms were obtained by GO functional enrichment analysis(P<0.05), and 20 signaling pathways were obtained from KEGG pathway enrichment, mainly involving neuroactive ligand-receptor interaction, serotonergic synapse, calcium signaling pathway, cAMP signaling pathway, dopaminergic synapse, retrograde endocannabinoid signaling, neurotrophin signaling pathway, gap junction, cholinergic synapse, estrogen signaling pathway, glutamatergic synapse and long-term potentiation. Molecular docking analysis showed that hydrogen bonding, π-π interaction and hydrophobic effecting may be the main forms of interaction. This study used the network of compound-target-pathway and molecular docking technology to screen the effective components of Valerianae Jatamansi Rhizoma et Radix against PTSD, and explore its anti-PTSD mechanism, so as to provide scientific basis for exploring the anti-PTSD drugs from traditional Chinese medicine and clarifying its mechanism of action.

ABSTRACT

Quality evaluation based on character identification of traditional Chinese medicinal materials is the wisdom crystallization of the long-term medication experience of the pharmacists in the past dynasties, and is a quality evaluation system with the characteristics of traditional Chinese medicine (TCM). Because of its simple language, easy to understand and easy to operate, it plays an important guiding role in the quality evaluation of TCM. Modern electronic sensory apparatus technology can realize the objective expression of TCM characters. Some scholars correlated their expression results with the contents of the main chemical components in TCM, proving that quality evaluation based on character identification of traditional Chinese medicinal materials has a certain scientific basis. However, the scientific connotation of quality evaluation based on character identification of traditional Chinese medicinal materials has not yet been clearly clarified. There is a lack of systematic research on which characters of TCM can truly reflect its quality. Therefore, the author summarizes quality evaluation based on character identification of traditional Chinese medicinal materials from three aspects. It makes clear that the idea of quality evaluation based on character identification of traditional Chinese medicinal materials is derived from analogical thinking, and combs the four stages of germination, development, prosperity and maturity experienced in its formation process, summarizes the modern research progress of this theory, clarifies that the role of the theory in evaluating the quality of medicinal materials, guiding the classification of commodity specifications, and harvesting and processing of medicinal materials. It is recommended that the follow-up should be strengthened on the research of quality evaluation based on character identification of traditional Chinese medicinal materials, make full use of electronic sensory instruments, liquid-mass spectrometry, biological efficacy evaluation and other technologies, strengthen the objective description of the characteristics of TCM, and attach importance to the analysis of the correlation between the overall characteristics of TCM and its efficacy, and establish a new research model related to the characteristics-active ingredients-pharmaceutical effects of TCM, in order to elucidate the scientific connotation of quality evaluation based on character identification of traditional Chinese medicinal materials, so as to better serve the quality evaluation of TCM.

ABSTRACT

This article aims to establish the fingerprints, determine the hemostatic pharmacodynamic indicators, and explore the spectrum-effect relationship of Notoginseng Radix et Rhizoma in 12 different specifications. Firstly, HPLC and liquid chromatography-mass spectrometry(LC-MS) were employed to establish the fingerprints of Notoginseng Radix et Rhizoma. The rat plasma recalcification experiment and the rat gastric bleeding experiment were conducted to determine the pharmacodynamic indicators, including plasma recalcification time(PRT), thrombin time(TT), prothrombin time(PT), and activated partial thromboplastin time(APTT). Afterwards, the partial least squares method was employed to explore the spectrum-effect relationship of Notoginseng Radix et Rhizoma in different specifications. Twenty-six common peaks were detected in the HPLC fingerprints of different specifications of Notoginseng Radix et Rhizoma, and 11 out of the 26 common peaks represented saponins. The content of dencichine was determined by LC-MS. The rat experiments showed that the pharmacodynamic indicators were significantly different among different specifications of Notoginseng Radix et Rhizoma. The spectrum-effect relationship was explored between 27 common components and pharmacodynamic indicators. Among them, 16 components had positive effects on the pharmacodynamic indicators of Notoginseng Radix et Rhizoma, and 11 exerted negative effects. This study provides a basis for the precision medication and quality control of Notoginseng Radix et Rhizoma.

ABSTRACT

The incidence of type 2 diabetes in China is increasing annually, and its chronic complications are very common. Macrovascular complications are the main cause of death in patients with type 2 diabetes mellitus. The pathogenesis of diabetic macrovascular complications is different from that of traditional cardiovascular diseases. It has been found that macrovascular complications of type 2 diabetes are not only related to traditional cardiovascular disease risk factors (age, gender, hypertension, smoking, body mass index, diabetes duration, serum lipid, and glycosylated hemoglobin), but also diabetic microvascular complications, some specific molecular proteins and individual genetic background. This article reviews the clinical factors, molecular proteins and genetic background that affect the incidence of macrovascular complications in type 2 diabetes.

ABSTRACT

To explore the interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students. From November 2015 to January 2016, 22 628 middle school students from Shenyang of Liaoning Province, Bengbu of Anhui Province, Xinxiang of Henan Province, Ulanqab of Inner Mongolia Autonomous Region, Chongqing Municipality, and Yangjiang of Guangdong Province were enrolled by using the multi-stage cluster convenience sampling method. A questionnaire was used to collect the data including demographic information, health literacy, second-hand smoke exposure, and psychopathological symptoms. A multivariate logistic regression model was used to analyze the interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students. The age of students was (15.36±1.79) years old, of which 10 990 were boys, accounting for 48.6% of total students. The detection rate of psychopathological symptoms was 29.1% (6 581/22 628). The detection rate of psychopathological symptoms in those who were exposed to second-hand smoke was 38.1% (2 401/6 304), which was higher than that in the non-second-hand smoke exposure group [25.6% (4 180/16 324)] (0.001). The (95) of the interaction between medium and low levels of overall health literacy, low level of interpersonal dimension of health literacy and second-hand smoke exposure was 1.19 (1.15-1.24), 2.00 (1.92-2.10) and 1.59 (1.52-1.66), respectively. There was a positive interaction between middle and low levels of overall health literacy, low level of interpersonal dimension of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students.

ABSTRACT

Akkermansia muciniphila (A. muciniphila) is a normal flora of human gastrointestinal tract. The A. muciniphila abundance of intestinal flora in obese patients is significantly decreased. Many evidences suggest that A. muciniphila is negatively related to obesity, diabetes, cardiovascular diseases and low-grade inflammation. A. muciniphila not only plays a metabolic protective role by protecting the integrity of intestinal epithelial cells and mucus layer, but also plays an anti-inflammatory role by regulatory T cells, endogenous cannabinoid system and non-classical Toll-like receptor in the process of inflammatory reaction. This article reviews the relationship between A. muciniphila and obesity, and the molecular mechanism and application of A. muciniphila in obesity.

ABSTRACT

The construction of health file of patients with brucellosis in Qinghai Province was based on the Qinghai Provincial Public Health Network Information Platform. It was jointly participated and implemented by animal husbandry and veterinary departments, animal disease control centers, disease control centers and hospitals at all levels, to achieve standardized management of early detection, early diagnosis, early treatment, as well as follow-up, review, and efficacy evaluation. After analyzing the health file of brucellosis patients, we proposed to strengthen the propaganda of brucellosis, collect information from multiple diseases, share resources with multiple departments, integrate human resources and exert management responsibilities, and explore opinions and countermeasures suitable for local working conditions. The establishment of a health file for patients with brucellosis could fully grasp the diagnosis and treatment of brucellosis patients, facilitate the management of follow-up and review, and it was helpful to understand the distribution and prevalence of brucellosis in Qinghai Province, and to warn the epidemic trend.

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, which is characterized by complex pathogenesis, inconspicuous early symptoms, rapid progress and poor prognosis. Immunotherapy and targeted therapy are important methods to treat advanced and metastatic liver cancer in recent years. With the FDA's approval of sorafenib and other tyrosine kinase inhibitors and programmed cell death protein 1 and cytotoxic T lymphocyte-associated antigen-4 immune checkpoint inhibitors for the treatment of liver cancer, great progress has been made in single-agent therapy and combination therapy, bringing a new turning point for the improvement of survival rate of patients with advanced liver cancer. However, the mechanism of immunotherapy and drug resistance is still unclear, and its clinical application combined with targeted and other therapies is still under research, which needs to be further explored by researchers. In this paper, the clinical research progress of immunotherapy combined with other therapies in advanced hepatocellular carcinoma was reviewed, in order to grasp the current development trend of the treatment of hepatocellular carcinoma and provide reference for the further development direction of immunotherapy.

ABSTRACT

Programmed cell death protein 1 (PD-1) is an important immunosuppressive molecule, which combines with programmed cell death 1 ligand 1 (PD-L1) to initiate programmed T-cell death, leading to immune escape of tumor cells. Immune checkpoint inhibitors kill tumor cells by blocking the binding of PD-1 to PD-L1 and reactivating the patient's own immune system. With the approval of anti-PD-1 monoclonal antibodies nivolumab, pembrolizumab and anti-PD-L1 monoclonal antibody atezolizumab by FDA for the treatment of melanoma, advanced non-small cell lung cancer and other cancers, cancer treatment has ushered in a new dawn. However, only 20% of patients achieved long-term efficacy after treatment, and most patients relapsed later. Therefore, it is significant to identify effective biomarkers and develop new targets to improve the response of patients to immunotherapy. This article reviews on the mechanism of action of anti-PD-1/PD-L1 drugs in tumors, potential biomarkers and the mechanism of acquired drug resistance, as well as combination therapy under research.

ABSTRACT

@# Objective To investigate the relationship between various types of social support and suicide ideation, and whether the relationship varies by gender. Methods A total of 4 799 students in cluding freshmen and sophomores were recruited by stratified cluster sampling from 2 medical colleges in Anhui Province. We assessed demographic indicators, social support and suicidal ideation, etc. Logistic regression was used to analyze their gender differences and the relationship between social support and suicidal ideation. Results The prevalence of suicidal ideation was 6.2%, and no gender difference was found ( 2=1.224,P=0.269). The rate of suicidal ideation was higher with the decreasing of social support. Low levels of social support had independent effects on suicidal ideation among total samples and females respectively after controlling for confounding factors (all P<0.05), while low levels of social support, subjective social support and support availability increased the risk of suicidal ideation among males (P value was 0.049,0.002,0.031, respectively). In adolescents with low levels of social support, objective social support and various sources of social support, females versus males had higher risk to have suicidal ideation. Conclusions Low level of social support increased the risk of suicidal ideation among students in medical college, especially for girls. Groups at highest risk of suicidal ideation in relation to certain types of social support should be targeted with interventions accordingly.

ABSTRACT

Objective The proportion of multiple drugs and the irrational use of drugs increased significantly in the elderly patients (over 80 years). This study aimed to investigate the occurrence of potentially inappropriate medication (PIM) and analyzed the possible reasons related to PIM in elderly patients. Methods In this study,918 cases from Cadre Ward I of Research Center for Geriatrics of Nanjing General Hospital of Nanjing Military Region were selected from January to December in 2016. According to the Beers Criteria (Version 2015),we evaluated PIM in four subtypes,type 1 that is not related to the state of disease in elderly patients, type 2 that is related to the state of disease in elderly patients,type 3 which should be used carefully,and type 4 which is the inappropriate combination of non-anti-infective Drugs. The PIM influence factors were analyzed by logistic regression analysis. Results There are 521 cases (56.75%) of type 1 PIM. The first 3 drugs are Short and medium acting benzodiazepams,PPI and long acting benzodiazepams. There are 206 cases (22.4%) of type 2 PIM. The first 2 drugs are drugs associated with insomnia (oral hyperemia, stimulants, theo-phylline and caffeine) and drugs associated with dementia or cognitive impairment (anti-cholinergic drugs and H2 receptor antago-nists). There are 834 cases (90.85%) of type 3 PIM,which should be used carefully and 45 cases(4.90%) of type 4 PIM.45 cases (4.90%) of non-anti-infective drugs should be avoid or reduced as much as possible in consideration of renal function. The number of combined drug use(OR=5.331,95% CI:3.549-8.009),the age(OR=1.171,95% CI:1.093-1.249),the Chalson's comorbidity index (OR=1.964,95% CI:1.477-2.450) are risk factors of PIM. Conclusion The incidence of potentially inappropriate use of drugs is high among the elderly patients. Reducing the number of combined drugs is an important measure to avoid the occurrence of PIM in elderly patients.
