ABSTRACT

Objective:To understand the prevention and control progress of drinking water-borne endemic fluorosis in Henan Province, to evaluate the effects of prevention and control measures, and provide a basis for adjusting prevention and control strategies.Methods:In 2019, a general survey was conducted in all registered drinking water-borne endemic fluorosis villages in Henan Province to monitor the basic conditions of water improvement, the fluoride content of drinking water and the prevalence of dental fluorosis in children aged 8-12 years. The control compliance (water fluoride content qualified and the detection rate of dental fluorosis of children ≤30%) status of the villages was analyzed, and calculate the compliance rate.Results:A total of 17 504 drinking water-borne endemic fluorosis villages were monitored, among them, 17 352 villages with water improvement and 152 villages without water improvement, with a water improvement rate of 99.1%. Among the 3 685 water improvement projects constructed, 3 448 were in normal operation, and the normal operation rate was 93.6%. There were 13 526 villages with qualified drinking water fluoride content, and the qualified rate of water fluorine was 77.3%; the actual beneficiary population was 11 011 000, and the population benefit rate was 90.1%. The qualified rate of water fluoride in the villages with and without water improvement was 77.9% (13 512/17 352) and 9.2% (14/152), respectively; the qualified rate of water fluoride in the villages with water improvement was significantly higher than that in the villages without water improvement (χ 2=400.58, P < 0.05). A total of 498 527 children of 8 to 12 years old were examined, 68 972 cases of dental fluorosis were detected, the detection rate of dental fluorosis was 13.84%, and the dental fluorosis index was 0.3. The number of villages meeting the control standard was 12 488, and the compliance rate was 71.3%. Conclusions:In Henan Province, the water improvement projects in the drinking water-borne endemic fluorosis areas have been basically implemented, and the disease has been effectively controlled. However, there is still a certain gap with the target of the "13th Five-Year Plan on National Prevention and Control of Endemic Diseases", and timely rectification is needed to ensure the effectiveness of the water improvement projects.

ABSTRACT

Objective:To explore the effect of health education on drinking-water-borne endemic fluorosis in Henan Province.Methods:From 2008 to 2015, using prospective method and combining with the distribution of drinking-water-borne endemic fluorosis in Henan Province, 20-30 drinking-water-borne endemic fluorosis counties (cities, districts, referred to as counties) were selected as project counties in Henan Province each year, and 3 townships (towns) were selected in each project county. School health educational activities on prevention and treatment of drinking-water-borne endemic fluorosis were carried out in the classes of grade 4-6 in one central primary school in each township (town); 3 administrative villages were selected in each township (town) to carry out community health education activities. Before and after the health education activities, questionnaire surveys on health education of drinking-water-borne endemic fluorosis prevention knowledge were conducted among 30-50 primary school students of grade 5 in the central primary school and 15-30 housewives in the school location in each township (town), to evaluate the effect of health education.Results:The baseline survey included 29 085 primary school students and 14 361 housewives. After the health intervention, 25 671 primary school students and 12 821 housewives were surveyed. The awareness rate of primary school students increased from 56.12% before the intervention to 92.40% after the intervention (χ 2=27 395.3, P < 0.01), and that of housewives increased from 62.62% before the intervention to 91.76% after the intervention (χ 2=9 560.8, P < 0.01). Conclusions:After implementation of drinking-water-borne endemic fluorosis health education intervention, the awareness rates of prevention and treatment knowledge in primary school students and housewives in Henan Province are significantly increased. It is suggested that the scope of health education should be further expanded.

ABSTRACT

Objective:To investigate the relationship between medical students' employment intention in primary healthcare unit and their learning and psychological state through a questionnaire survey among clinical undergraduates.Methods:A cross-sectional survey was conducted among 821 graduates of a Medical University in 2017 to investigate their employment intention, learning and psychological status and employment plan. The learning and psychological status was evaluated by a self-designed questionnaire. Independent-sample t test, variance analysis and multiple linear regression analysis were used to examine the relevant factors affecting medical students' employment intention in primary healthcare by SPSS 21.0 version. Results:A total of 810 questionnaires were distributed and 753 questionnaires were included in the analysis. The employment intention of working in primary healthcare units of medical students was (4.61±2.24). Students in the advanced class had lower willingness to work in primary healthcare unit (the group of students with higher entrance examination scores) ( P<0.05), and students with higher learning pressure and greater pressure of doctor-patient relationship were more reluctant to work in primary healthcare units ( P<0.05). In terms of the employment plan, students who focus on their professional counterparts are more willing to work in primary healthcare unit, while those who pay more attention to salary are less willing to work in primary healthcare unit ( P<0.05). Conclusion:Improving the incentive policies for working in primary healthcare unit, actively relieving psychological pressure of medical students, and increasing the training of doctor-patient communication can have a positive effect on improving the willingness of medical students to have an employment intention in primary healthcare unit.

ABSTRACT

Objective:To investigate the expression of the cell cycle mitotic spindle checkpoint serinel/threonine kinase (BUB1) gene in breast cancer and its relationship with the prognosis,and further explore the intervention effect of japonicone A on BUB1 gene in breast cancer cells. Method:Through Oncomine,GEPIA,GEO database,bc-GenExMiner v4.5 and Kaplan-Meier Plotter database, in-depth mining was conducted for BUB1 gene expression-related data,in order to explore the difference in the expression of BUB1 gene in breast cancer tissues and normal breast tissues and its relationship with patient prognosis. Encyclopedia of Cancer Cell Lines (CCLE) was used to analyze the expression of BUB1 in T cells and B cells of breast cancer tissues,STRING database was used to draw BUB1-related protein network diagram and gene ontology(GO) function annotation and analyze relevant pathways in Kyoto Encyclopedia of Genes and Genomes (KEGG). The tumor immune assessment resource(TIMER) database was used to analyze the expression of BUB1 in immune infiltrates and its impact on the survival and prognosis of patients with gastric cancer. Finally, the effect of japonicone A on the expression level of BUB1 gene in breast cancer cells was further analyzed. Result:①The mRNA level of BUB1 in breast cancer tissues was significantly higher than that of normal tissue samples, but the expression levels of BUB1 in breast cancer patients with different molecular subtypes varied. ② Increased expression of BUB1 could lead to longer distant metastasis-free survival(DMFS),overall survival(OS),and recurrence free survival(RFS) in luminal A subtypes. ③ BUB1 was positively correlated with structural maintenance of chro-mosome 4(SMC4) mRNA expression level, and might be interacted with 10 proteins, such as NUF2, with the strongest interaction relationship. ④ The high expression of BUB1 mRNA in CD8<sup>+ </sup>T cells and neutrophils in breast invasive carcinoma(BRCA) and BRCA-basal had a better two-year survival prognosis than the low expression group;the low expression of BUB1 mRNA in B cells in BRCA-Her2 had a better two-year survival prognosis than the high expression group. ⑤ GEO database analysis data set GSE85871 found that japonicone A could down-regulate the expression of BUB1 gene in breast cancer MCF7 cells. Conclusion:BUB1 gene is highly expressed in breast cancer tissues and related to the prognosis of breast cancer and immune cell infiltration. This may be a new potential therapeutic target for japonicone A to intervene breast cancer cells.

ABSTRACT

Buxue Yimu Pill (BYP) is a classic gynecological medicine in China, which is composed of Angelica sinensis (Oliv.) Diels, Leonurus japonicus Houtt, Astragalus membranaceus (Fisch.) Bunge, Colla corii asini and Citrus reticulata Blanco. It has been widely used in clinical therapy with the function of enriching Blood, nourishing Qi, and removing blood stasis. The current study was designed to determine the bioactive molecules and therapeutic mechanism of BYP against hemorrhagic anemia. Herein, GC-MS and UPLC/Q-TOF-MS/MS were employed to identify the chemical compounds from BYP. The genecards database (https: //www.genecards.org/) was used to obtain the potential target proteins related to hemorrhagic anemia. Autodock/Vina was adopted to evaluate the binding ability of protein receptors and chemical ligands. Gene ontology and KEGG pathway enrichment analysis were conducted using the ClusterProfiler. As a result, a total of 62 candidate molecules were identified and 152 targets related to hemorrhagic anemia were obtained. Furthermore, 34 active molecules and 140 targets were obtained through the virtual screening experiment. The data of molecular-target (M-T), target-pathway (T-P), and molecular-target-pathway (M-T-P) network suggested that 32 active molecules enhanced hematopoiesis and activated the immune system by regulating 57 important targets. Pharmacological experiments showed that BYP significantly increased the counts of RBC, HGB, and HCT, and significantly down-regulated the expression of EPO, IL-6, CSF3, NOS2, VEGFA, PDGFRB, and TGFB1. The results also showed that leonurine, leonuriside B, leosibiricin, ononin, rutin, astragaloside I, riligustilide and levistolide A, were the active molecules closely related to enriching Blood. In conclusion, based on molecular docking, network pharmacology and validation experiment results, the enriching blood effect of BYP on hemorrhagic anemia may be associated with hematopoiesis, anti-inflammation, and immunity enhancement.

ABSTRACT

Background@#(Introduction): Zika virus (ZIKV), a mosquito-borne flavivirus, causes the outbreaks of Latin America in 2015 - 2016, with the incidence of neurological complications. Sunitinib malate, an orally bioavailable malate salt of the tyrosine kinase inhibitor, is suggested as a broadspectrum antiviral agent against emerging viruses like severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2. @*Materials and Methods@#This study investigated the antiviral efficacy and antiviral mechanisms of sunitinib malate against ZIKV infection using cytopathic effect reduction, virus yield, and time-of-addition assays. @*Results@#Sunitinib malate concentration-dependently reduced ZIKV-induced cytopathic effect, the expression of viral proteins, and ZIKV yield in supernatant with 50% inhibitory concentration (IC 50 ) value of 0.015 μM, and the selectivity index of greater than 100 against ZIKV infection, respectively. Sunitinib malate had multiple antiviral actions during entry and post-entry stages of ZIKV replication. Sunitinib malate treatment at entry stage significantly reduced the levels of ZIKV RNA replication with the reduction of (+) RNA to (-) RNA ratio and the production of new intracellular infectious particles in infected cells. The treatment at post-entry stage caused a concentration-dependent increase in the levels of ZIKV (+) RNA and (-) RNA in infected cells, along with enlarging the ratio of (+) RNA to (-) RNA, but caused a pointed increase in the titer of intracellular infectious particles by 0.01 and 0.1 μM, and a substantial decrease in the titer of intracellular infectious particles by 1 μM. @*Conclusion@#The study discovered the antiviral actions of sunitinib malate against ZIKV infection, demonstrating a repurposed, host-targeted approach to identify potential antiviral drugs for treating emerging and global viral diseases.

ABSTRACT

Objective:To discuss the effect of bipolar radio frequency (RF) in combination with small incision on lower facial (cheek, chin and neck) shaping and rejuvenation.Methods:From August 2019 to June 2020, 26 patients (aged 35-60 years, with mean 45 years) required for facial rejuvenation and received the fine liposuction in the lower cheek, mandibular margin and submental neck area in Beijing Huangsi Plastic Surgery Hospital. With the help of bipolar RF device - EMBRACE RF (diamond carving), the facetite face and hand radiofrequency were adopted for the subcutaneous tissue to tighten the skin. A concealed small incision was made from the front of the ear to the posterior ear. The superficial layer of the superficial muscular aponeuritic system (SMAS) was stripped, folded, tightened and suspended. The excessive skin was removed while reducing multilayer tension. The incision was cosmetically sutured.Results:All 26 patients had their wounds primary healing, with no complications such as skin necrosis and sensory disorder. All the 24 patients were followed up for 6-12 months. Their scars were concealed and tiny, the skin was tight, the lifting effect was obvious, and the pouch of mouth corners disappeared or alleviated. The contour of the mandibular margin was defined and the mental cervical angle was clear. The shape of the neck was slender and the fat chin was significantly improved. The effect of facial rejuvenation was distinct. Two patients felt it worked but did not achieve the expected results. They were satisfactory after giving the second surgery 6 months later. The satisfactory rate of the first surgery was 92.3% in 24 patients.Conclusions:Bipolar RF in combination with small incision lifting surgery is effective in lower facial (cheek, chin and neck) shaping and rejuvenation. The trauma is little and the wound is recovered fast. The scar is concealed and tiny. It is worthy of clinical application.

ABSTRACT

OBJECTIVES@#To study the antitumor effect of piceatannol (PIC) on malignant melanoma @*METHODS@#B16F10 cells were cultured @*RESULTS@#The cell viability of B16F10 decreased with increasing PIC concentration. The results of the Transwell assay showed that invasion ability decreased with increasing PIC concentration, and healing time was prolonged at increased PIC concentration in the wound healing assay. Western blot results showed that PIC mainly inhibited the phosphorylation of Syk and inhibited the expression of MMP-2, MMP-9, and VEGF. RNA interference pointed out that blocking the expression of Syk can reveal the same inhibition effect on B16F10 cells as PIC. @*CONCLUSIONS@#PIC might block the progression of malignant melanoma by inhibiting spleen tyrosine kinase.

ABSTRACT

Epilepsy is one of the most common neurological conditions, which is characterized by recurrent unprovoked seizures. Drug treatment is still the main method for the disease. Although remarkable progress has been made in the development of antiepileptic drugs in recent years, there is still a poor curative effect on patients with refractory epilepsy. This review will focus on the current status and pathogenesis of epilepsy, as well as the antiepileptic drugs (targeting sodium channels, calcium channels, potassium channels, and the balance of γ-aminobuyric acid /glutamate system, respectively) that have been developed based on classical epileptogenic mechanisms. Further the antiepileptic drugs acting on new targets (epigenetic interferers, synaptic vesicle glycoprotein 2A modulators, mammalian target of rapamycin signal pathway blockers, carbonic anhydrase inhibitors, cannabidiol and adenosine inhibitors) have also been discussed.

ABSTRACT

Objective:To explore the role of group 2 innate lymphoid cells (ILC2) in atopic dermatitis (AD) .Methods:C57BL/6J and Rag1 -/- mice served as research objects. The C57BL/6J mice were divided into 2 groups: model group topically treated with calcipotriol (MC903) on both ears every day for 14 consecutive days, control group topically treated with anhydrous ethanol alone at the same time. On day 15, peripheral blood samples were collected from the mice. After the sacrifice, the ear skin tissues were obtained for histopathological examination, and the spleens were resected. Real-time fluorescence-based quantitative PCR was performed to determine the expression of inflammatory factors in the skin and spleen tissues, and flow cytometry to determine the proportion of ILC2 in the skin tissues. The Rag1 -/- mice were divided into model group, control group and experimental group: the Rag1 -/- mice in the model group and control group received the same treatment and evaluation as the C57BL/6J mice; two days before the topical treatment with MC903, the Rag1 -/- mice in the experimental group started to be intraperitoneally injected with the monoclonal antibody CD90.2 at a dose of 300 μg/150 μl once every other 2 days for 7 sessions, with the purpose of antagonizing the function of ILC2, and other treatments were the same as those in the model group. Skin manifestations were observed, and histopathological features were evaluated. Two-independent-sample t test was used for comparisons between 2 groups, and one-way analysis of variance for comparisons among multiple groups. Results:In the model group, the ear skin of the C57BL/6J mice was apparently red, swollen and dry with crusts, and hematoxylin and eosin (HE) staining showed increased thickness of the epidermis and dermal infiltration of eosinophils; the serum level of IgE (6 751.016 ± 282.324 μg/L) was significantly higher in the model group than in the control group (6 387.038 ± 267.853 μg/L, P= 0.007) , so were the expression of interleukin (IL) -4, IL-13 and interferon (IFN) -γ in the skin tissues ( P= 0.005, 0.012, < 0.001, respectively) , but there was no significant difference in IL-5 expression ( P= 0.190) ; the expression of IL-4, IL-13 and IFN-γ in the spleen was significantly higher in the model group than in the control group (all P < 0.001) , but there was no significant difference in IFN-γ expression ( P= 0.278) ; moreover, the model group showed significantly increased proportion of ILC2 (5.604% ± 2.105%) compared with the control group (1.750% ± 1.104%, P= 0.003) . In the Rag1 -/- mice, the ear skin was obviously red, swelling and dry with crusts in the model group, and HE staining showed increased epidermal thickness and eosinophil infiltration in the dermis; the model group showed significantly increased expression of IL-4, IL-5, thymic stromal lymphopoietin (TSLP) and IL-33 in skin tissues ( P= 0.010, 0.043, 0.034, 0.007, respectively) , but no significant difference in the expression of IL-13 or IFN-γ ( P= 0.274, 0.697, respectively) compared with the control group; the proportion of ILC2 was significantly higher in the model group (5.165% ± 2.436%) than in the control group (0.835% ± 0.578%, P= 0.014) ; the experimental group showed markedly attenuated skin lesions, reduced epidermal thickness and number of eosinophils infiltrating in the dermis, but no significant difference in the expression of IL-4, IL-5, IL-13, TSLP or IL-33 compared with the model group (all P > 0.05) . Conclusion:ILC2 play a role in the mice with AD-like inflammatory response induced by MC903, which dose not depend on adaptive immunity.

ABSTRACT

Objective:To evaluate the effect of health education project on prevention and control of endemic diseases in Henan Province.Methods:According to the distribution and condition of endemic diseases in Henan Province, from 2008 to 2015, five project counties (cities, districts, referred to as counties) were selected in each provincial city. Three townships (towns) were selected from each project county as project townships (towns), and one central primary school and the village where the school was located were selected from each township (town) as health education survey sites. The prospective study method was adopted. Firstly, the students in the primary school of the project township (town) and the housewives in the project village were investigated with questionnaire. The intervention activities of health education were carried out in the county, township (town), village and school of the project. The intervention effect of health education was evaluated by questionnaire survey two months later.Results:There were 111 870 people investigated in Henan Province, including 74 580 students and 37 290 housewives. A total of 99 671 people were surveyed after the intervention, including 66 249 students and 33 422 housewives. Elementary student's awareness rate of endemic diseases prevention and control knowledge increased from 59.74% before intervention to 92.89% after intervention, the housewives' awareness rate increased from 65.62% before intervention to 91.82% after intervention. The awareness rate of the target population increased from 61.70% before intervention to 92.53% after intervention ( P < 0.01); among them, the awareness rates of iodine deficiency disorders, drinking water type fluorosis, coal-burning type fluorosis, drinking water type arsenic poisoning, Kashin-Beck disease and Keshan disease were significantly increased ( P < 0.01). Conclusion:With the implementation of health education project, the awareness rate of knowledge on endemic diseases has increased distinctly.

ABSTRACT

Objective:To understand the status of drinking water-borne endemic fluorosis in Henan Province, so as to provide scientific basis for improving prevention and control strategies.Methods:Ten counties (districts, referred to as counties) were selected from drinking water-borne endemic fluorosis areas of Henan Province in 2018. Three villages in each project county were selected according to the disease status of mild, moderate and severe conditions, and the operation status of water improvement projects, water fluoride content and dental fluorosis among children aged 8 to 12 years in each diseased village were monitored.Results:Totally 30 villages were surveyed, all of which were in the water improvement projects; a total of 25 water improvement projects were monitored, all of them were in normal operation, and the water fluoride exceeding standard rate was 28.00% (7/25), the qualified rate of water fluoride in the water improvement projects was 72.00% (18/25). Among them, 21 villages were in normal operation and the water fluoride in the water improvement projects met national standard. In which the detection rate of dental fluorosis among children aged 8 to 12 years was 36.71% (606/1 651), the index of dental fluorosis was 0.74, and the epidemic intensity was extremely mild. Water fluoride of water improvement projects in 9 villages exceeded the national standard, where the detection rate of dental fluorosis among children aged 8 to 12 years was 43.57% (261/599), the index of dental fluorosis was 0.78, and the epidemic intensity was extremely mild. The detection rate of dental fluorosis among children in the villages where the water fluoride of water improvement projects exceeded the national standard was higher than that in the villages where the water fluoride of water improvement projects met the national standard (χ 2=8.752, P < 0.01). Conclusions:The excessive fluorine content in the water of water improvement projects is still serious, and the epidemic is still severe. It is necessary to strengthen the scientific demonstration of the water improvement project construction and the project acceptance upon completion, so as to prevent unqualified projects from being put into use. We will carry out regular water quality monitoring and promptly rectify projects with water quality exceeding the standards.

ABSTRACT

BACKGROUND@#Acute type A aortic dissection (ATAAD) and acute type A intramural hematoma (ATAIMH) are life-threatening diseases with high mortality. To better understand their clinical features in the Chinese population, we analyzed the data from the first Registry of Aortic Dissection in China (Sino-RAD) to promote the understanding and management of the diseases.@*METHODS@#All patients with ATAAD and ATAIMH enrolled in Sino-RAD from January 1, 2012 to December 31, 2016 were involved. The data of patients' selection, history, symptoms, management, outcomes, and postoperation complications were analyzed in the study. The continuous variables were compared using the Student's t test for normal distributions and the Mann-Whitney U test for non-normal distributions. Categorical variables were compared using the Chi-square test or Fisher exact test.@*RESULTS@#A total of 1582 patients with ATAAD and 130 patients with ATAIMH were included. The mean age of all patients was 48.4 years. Patients with ATAAD were significantly younger than patients with ATAIMH (48.9 years vs. 55.6 years, P < 0.001). For the total cohort, males were dominant, but the male ratio of patients with ATAAD was significantly higher compared to those with ATAIMH (P = 0.01). The time range from the onset of symptom to hospitalization was 2.0 days. More patients of ATAIMH had hypertension than that of ATAAD (82.3% vs. 67.6%, P < 0.05). Chest and back pain were the most common clinical symptoms. Computerized tomography (CT) was the most common initial diagnostic imaging modality. 84.7% received surgical treatment and in-hospital mortality was 5.3%. Patients with ATAAD mainly received surgical treatment (89.6%), while most patients with ATAIMH received medical treatment (39.2%) or endovascular repair (35.4%).@*CONCLUSIONS@#Our study suggests that doctors should comprehensively use clinical examination and genetic background screening for patients with ATAAD and ATAIMH and further shorten the time range from symptoms onset to intervention, achieving early diagnosis and treatment, thereby reducing the mortality rate of patients with aortic dissection in China. We should standardize the procedures of aortic dissection treatment and improve people's understanding. Meanwhile, the curing and transferring efficiency should also be improved.

ABSTRACT

Neuropathic pain (NP) is a medical problem that has been bothering human beings and seriously affects people's quality of life. Although great progress has been made in the study of NP in recent years, there are still many patients who are ineffective to the existing treatments. At present, drug therapy is still the main method to relieve pain, however, adverse drug reactions has hindered the curative effects of drugs. It is extremely urgent to find new drug targets and reduce the adverse effects of existing drugs. This review will mainly describe the current situation and pathogenesis of neuropathic pain, effectiveness and limitations of existing drugs for treating neuropathic pain, and the current status of drug discovery.

ABSTRACT

Thoracic aortic dissection (TAD) without familial clustering or syndromic features is known as sporadic TAD (STAD). So far, the genetic basis of STAD remains unknown. Whole exome sequencing was performed in 223 STAD patients and 414 healthy controls from the Chinese Han population (N = 637). After population structure and genetic relationship and ancestry analyses, we used the optimal sequence kernel association test to identify the candidate genes or variants of STAD. We found that COL3A1 was significantly relevant to STAD (P = 7.35 × 10

ABSTRACT

There has been a long history since human beings began to realize the existence of post-traumatic symptoms. Posttraumatic stress disorder (PTSD), a diagnostic category adopted in 1980 in the Diagnostic and Statistical Manual of Mental Disorders-Ⅲ, described typical clusters of psychiatric symptoms occurring after traumatic events. Abundant researches have helped deepen the understanding of PTSD in terms of epidemiological features, biological mechanisms, and treatment options. The prevalence of PTSD in general population ranged from 6.4% to 7.8% and was significantly higher among groups who underwent major public traumatic events. There has been a long way in the studies of animal models and genetic characteristics of PTSD. However, the high comorbidity with other stress-related psychiatric disorders and complexity in the pathogenesis of PTSD hindered the effort to find specific biological targets for PTSD. Neuroimage was widely used to elucidate the underlying neurophysiological mechanisms of PTSD. Functional MRI studies have showed that PTSD was linked to medial prefrontal cortex, anterior cingulate cortex and sub-cortical structures like amygdala and hippocampus, and to explore the functional connectivity among these brain areas which might reveal the possible neurobiological mechanism related to PTSD symptoms. For now, cognitive behavior therapy-based psychotherapy, including combination with adjunctive medication, showed evident treatment effects on PTSD. The emergence of more effective PTSD pharmacotherapies awaits novel biomarkers from further fundamental research. Several natural disasters and emergencies have inevitably increased the possibility of suffering from PTSD in the last two decades, making it critical to strengthen PTSD research in China. To boost PTSD study in China, the following suggestions might be helpful: (1) establishing a national psychological trauma recover project, and (2) exploring the mechanisms of PTSD with joint effort and strengthening the indigenized treatment of PTSD.

ABSTRACT

Background: Lung adenocarcinoma has increased incidence over the past years and is the cause for almost 50% of deaths attributable to lung cancer. The objective of this paper is to identify activated pathways associated with lung adenocarcinoma based on gene co-expression network analysis. Materials and Methods: Kyoto Encyclopedia of Genes and Genomes pathway analysis of dysregulated genes was performed based on Expression Analysis Systematic Explorer test to illuminate the biological pathways. Co-expression networks of lung adenocarcinoma in different tumor Stages (IA, IB, IIA, IIB, IIIA, IIIB, and IV) were constructed by Empirical Bayes approach to reweight gene pair scores. Pathway activity analysis was conducted to compute the distribution of pathways in different stages and to identify “activated” pathways in lung adenocarcinoma. Results: We evaluated 211 dysregulated genes between lung adenocarcinoma patients and normal controls. Pathway activity analysis was performed and P values of pathways, which obtained from co-expression networks (Stage IA, IB, IIA, IIB, IIIA, IIIB, and IV), were calculated. Cell cycle, progesterone-mediated oocyte maturation, and oocyte meiosis were activated during all stages in lung adenocarcinoma. Conclusions: We successfully identified three activated pathways (cell cycle, progesterone-mediated oocyte maturation, and oocyte meiosis) in different Stages (IA, IB, IIA, IIB, IIIA, IIIB, and IV) of lung adenocarcinoma
