Bioinformatics Study of Plasma Differentially Expressed Proteins in H-Type Hypertension with or without Acute Cerebral Infarction

Objective: To investigate the bioinformatics of differentially expressed proteins in plasma in patients with acute cerebral infarction associated with H-type hypertension. Methods: Gene chip public database (gene expression omnibus, GEO) GDS4521 chip data, in the chip in 30 cases of H patients with acute cerebral infarction with high blood pressure and age, gender, matching the 20 H hypertension patients as the research object, collects the mononuclear cells (PBMCs) is used to detect the gene chip, using the GO (gene Ontology, GO), protein function analysis tools such as KEGG, screening and analysis of enrichment of differentially expressed genes function and related signaling pathway. Results: 31 genes in PBMCs were significantly changed in h-type hypertension and H-type hypertension with acute cerebral infarction, 32 of which were increased and 2 of which were decreased. GO analysis showed that in terms of biological processes, the genes related to inflammatory response and neutrophil chemotaxis were the most. In terms of molecular function, chemokine activity-related genes are the most. KEGG signaling pathway analysis showed that the most differentially expressed genes were located in the TNF signaling pathway. Conclusion: H-type hypertension with acute cerebral infarction has a variety of functional proteins and signaling pathways changes, suggesting that inflammatory response in H-type hypertension with acute cerebral infarction recovery period may still play a role in the prognosis and reactivation of the disease.

Advances in the Treatment of Advanced Non-Small Cell Lung Cancer

In recent years, the incidence of lung adenocarcinoma has been increasing, and now it has become the largest type of non-small cell lung cancer (NSCLC). Currently, treatment of advanced NSCLC consists of several modalities: systemic chemotherapy, local radiation therapy, and targeted therapy (including most recently immunotherapy). In the past decade, the discovery of new molecular subtypes, the search for tumor driver gene mutations, the development of targeted molecular targeted drugs, or targeted therapy to suppress tumor angiogenesis and regulate tumor immune response have been the main directions of NSCLC research and clinical diagnosis and treatment. At present, platinum-based chemotherapy is widely used in NSCLC patients clinically. Platinum-based chemotherapy drugs can effectively prolong the survival time of patients and improve their quality of life, but the incidence of adverse reactions is still high. Therefore, it is necessary to find a drug that can improve the efficacy of patients and reduce the adverse reactions of platinum chemotherapy drugs to NSCLC patients.

Study on the Relationship between Psychological Stress and Doctor-Patient Relationship of Cancer Patients and Their Families

Objective: To research the relationship between psychological stress and doctor-patient relationship of cancer patients and their families. Methods: The patients were randomly divided into the intervention group and the control group, and PDRQ-15, pcl-c, SAS and SDS scales were selected as evaluation indexes, and the levels of norepinephrine and dopamine were compared between the patients diagnosed with PTSD cancer and those without PTSD. Results: 1) The total score of PCL-C, SAS, SDS, PDRQ-15 scale of the cancer patients and their families after the intervention of clinical psychological care was significantly lower than that of before intervention and the control group. 2) The correlation coefficients between PCL-C, SAS, SDS and PDRQ-15 of cancer patients and their relatives were 0.971, 0.952 and 0.939 respectively. The significant test P value was less than 0.05 and the difference was statistically significant. 3) The plasma levels of dopamine and norepinephrine in cancer patients under stress were significantly higher than those in cancer patients without stress (P Conclusion: After psychological Intervention of cancer patients and their families, post-traumatic stress disorder, anxiety, depression and doctor-patient relationship were all improved.

A Study on the Association between Patients with Post-Traumatic Stress Disorder in Li and Han Ethnic Groups in Hainan Province and DNA Methylation of Brain-Derived Neurotrophic Factor Genes

Objective: To explore the pathogenesis of PTSD in the brain-derived neurotrophic factor (BDNF) gene methylation of patients with posttraumatic stress disorder (Posttraumatic Stress Disorder, PTSD) in Hainan Province, the relationship between the influence of BDNF gene methylation and the influence of PTSD. Methods: A case-control study method was adopted, strictly in accordance with DSM-IV and PTSD diagnosis, and 150 Li PTSD patients matched with gender and age of 300 Han PTSD patients were selected as the research objects. The peripheral venous whole blood of the subjects was drawn, genomic DNA was extracted, modified with bisulfite, and directly sequenced to quantitatively detect the methylation status of the CpG island in the promoter region of brain-derived neurotrophic factor (BDNF). Results: The results showed that the methylation levels of CPGl, CPG2, CPG3, CPG4, CPG5, CPG6, CPG7, CPG9, CPGl2, CPGl3, CPGl4, CPGl5, CPGl6, CPGl7, and CPGl8 in THE BDNF promoter were significantly different between the HAN PTSD group and the Li PTSD group (P < 0.001). Conclusion: It is suggested that CPG methylation in the promoter region of BDNF gene is closely related to patients with PTSD. There is a statistical difference in the level of CpG methylation in the promoter region of BDNF gene in PTSD between Li and Han ethnic groups in Hainan Province. CpG methylation in the promoter region of BDNF gene may be used as a biomarker for the diagnosis of PTSD.

Effect of Cognitive Behavioral Intervention Therapy on Immune Index in Patients with Breast Cancer

Objective: To explore the effect of cognitive behavioral intervention therapy on the cellular immune function of patients undergoing radical mastectomy for the first time, and to provide a scientific basis for improving the treatment of breast cancer patients. Methods: 100 patients with breast cancer who were eligible for admission to the Department of Breast Surgery, Hainan Provincial People’s Hospital from January 2016 to December 2017 were selected as subjects. It is the first time to improve the radical mastectomy. They were randomly divided into control group and intervention group, 50 cases each. The control group used conventional treatment and routine care. On the basis of this, the intervention group conducted cognitive behavioral interventions including cognitive reconstruction and behavioral therapy. The patients were measured for serum IL-2, IL-4, IL-6, IL-8 and TNF-α levels on the second day after admission and three months after discharge. The changes of serum IL-2, IL-4, IL-6, IL-8 and TNF-α levels in the two groups were compared before and after cognitive intervention. Results: The concentrations of IL-2, IL-4, IL-6, IL-8 and TNF-α in the serum of the intervention group and the control group before intervention were compared. The difference was not statistically significant (P > 0.05). After the intervention, the serum levels of IL-2, IL-4 and IL-8 in the intervention group were lower than before the intervention. The concentration of TNF-α was higher than before the intervention. The difference was statistically significant (P Conclusion: Cognitive behavioral intervention therapy can change the levels of IL-2, IL-4, IL-6, IL-8 and TNF-α in serum of breast cancer patients. It has a positive effect on the regulation of immune function in breast cancer patients.

Research Progress on the Relationship between Intestinal Flora and Mental and Psychological Diseases

The effects of microorganisms on the central nervous system are manifested in both health and disease states. The symbiotic microorganisms in the human gut have certain effects on the brain development before and after birth. Chronic inflammation in patients with irritable bowel syndrome (IBS), psychiatric disorders such as PTSD, anxiety disorders, etc., is likely to be associated with an imbalance in gut flora. Intestinal flora regulates the central nervous system mainly through nerve, endocrine, metabolic and immune pathways. The mechanisms involved in the influence of intestinal flora on the central nervous system are diverse, so it is necessary to explore the role of intestinal flora in mental and psychological diseases.

Research Progress on Post-Traumatic Stress Disorder and Its Animal Model

Posttraumatic stress disorder (PTSD) is to a persistently severe mental disorder which is caused by individual exposure to some unusual threatening or catastrophic stressful events. Its essential clinical manifestations refer to repeated playback of traumatic experience, durative avoidance of related clues, mental numbness or affection paralysis, and persistent increase of vigilance level. At present, the pathogenesis of PTSD has not been fully elucidated, and the clinical therapeutic effect has not been ideal. Generally, the classical animal model of PTSD is mouse;the domestic and international researches in the animal model of PTSD in recent years remain active, which are summarized as follows.

BDNF Gene Frequency Distribution in Li and Han Ethnic Groups in Hainan Province and Its Comparison with Other Countries and Regions

Objective: To explore the distribution characteristics of BDNF gene frequency in Li and Han nationalities in Hainan province. Methods: In June 2018-2019 and march to the people’s hospital of Hainan province health volunteers, 152 cases (Li 80, Han, 72), the application of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method to detect the polymorphism of BDNF gene (rs6265), and compared with other countries and regions of ethnic comparison between BDNF gene frequency distribution. Results: No statistical difference was found in rs6265 genotype distribution of BDNF gene in Li and Han ethnic groups (P = 0.3358, P = 0.0892, P = 0.1549). Comparison of BDNF allele frequency between Li and other ethnic groups showed statistically significant differences with other ethnic groups in China and Europe (P = 0.0384, P = 0.0000), but not statistically significant differences with Japan (P = 0.1164). Conclusion: BDNF gene (rs6265) has polymorphism in both Li and Han ethnic groups in Hainan Province. Compared with ethnic groups in other countries and regions, the polymorphism distribution is ethnically different.

Objective: To study the association between post-traumatic stress disorder (PTSD) and serotonin transporter promoter (5-HTTLPR) gene polymorphism in Han children in Hainan;to explore the genetic mechanism of PTSD in children. Methods: 50 patients with post-traumatic stress disorder and healthy children in Han nationality in Hainan were selected. Detection of 5-HTTLPR gene polymorphism by polymerase chain reaction (PCR) and amplified fragment length polymorphism, the genotype and allele frequencies were analyzed using a case-control association analysis method. Results: There were 4, 14 and 32 cases of LL, SL and SS in the post-traumatic stress disorder group of Hainan Han children, and 13, 20 and 17 cases in the control group. From the perspective of gene frequency, the L gene of post-traumatic stress disorder appeared 22.0%, and S appeared 78.0%. In the control group, L appeared 46.0%, and S appeared 54.0%. There were significant differences in genotype and gene frequency (P Conclusion: The 5-HTTLPR gene polymorphism in Hainan Han children may be associated with post-traumatic stress disorder.

Comorbidity between Neurotic Depression and Post-Traumatic Stress Disorder (PTSD)

Comorbidity with PTSD has been studied at home and abroad in follow-up studies following major traumatic events, indexing patients diagnosed with PTSD and investigating rates of comorbidity and other psychiatric disorders. In practical clinical practice, the majority of patients with PTSD are diagnosed with neurosis and depression, but the clinical manifestations and treatment of some of these patients are more complicated and difficult, and it is clinically found that these patients may have comorbidities and other mental disorders. This study in hospitalized patients with neurosis and depression as the main research object, through the investigation found that some patients (36.4%) of comorbid PTSD, just, this part of the patients reported by a traumatic event is not CCMD-3 defined in the “unusual” traumatic event. Therefore, the results of this study suggest that attention should be paid to the collection of patients’ medical history, especially the inquiry of traumatic experiences. This study is only a preliminary study with a small sample size, and the conclusions obtained need to be further confirmed in future studies.
