RESUMO
Objective:To screen genetic and epigenetic expression differences associated with pulmonary embolism through integrated bioinformatics analysis.Methods:Four patients with pulmonary embolism and healthy physical examination in the Third Affiliated Hospital of Xinjiang Medical University in 2019 were selected as the research objects, using high-throughput sequencing technologies and methylation chip technology to detect, screening and integrated peripheral blood difference genomes and the epigenome data to identify the pathogenesis of pulmonary embolism caused by methylation of drive and differentially expressed genes, GO and KEGG enrichment analysis were performed.Results:Coexpression analysis of DNA methylation and gene expression data between the pulmonary embolism group and the healthy control group showed that differential methylation in the upstream region of genes was negatively correlated with gene expression. Among them, 8 significantly methylated genes in the upstream region of genes were screened out, and independent sample t-test and Pearson correlation analysis were done. In the pulmonary embolism group, there were 6 significant methylated genes of TSS1500, namely TSPO2, C1QA, AQP1, TNFSF9, MIA and STAB1, and the differential expression multiple log2FC of corresponding genes was 1.298, 1.629, 1.024, 2.746, 2.539, 1.060, respectively. The correlation between gene expression and gene methylation were -0.908, -0.900, -0.824, -0.784, -0.783, -0.779, respectively, and the methylation differences between the two groups were -0.049, -0.053, -0.048, -0.057, -0.050, respectively. -0.053 ( P < 0.05). There were three significantly methylated genes in the TSS200 region, namely TSPO2, SLC9A, and SIGLEC1. The gene expression differential multiple log2FC was 1.298, -2.252, and 1.866, respectively. The correlation between gene expression and gene methylation was -0.860, -0.774, and -0.739, respectively. The methylation difference between the two groups was -0.051, 0.027, -0.048 ( P < 0.05). In the pulmonary embolism group, 7 genes, including TSPO2, C1QA, AQP1, TNFSF9, MIA, STAB1 and SIGLEC1, showed hypomethylation and high expression in the TSS region. SLC9A3 gene showed high methylation and low expression. In the analysis of GO function, significant enrichment was obtained in complement activation, immune response and activation protein cascade. In the KEGG signaling pathway, the immune system, bacterial infection, and signaling molecules and interactions are significantly enriched, thereby regulating the occurrence of pulmonary embolism. Conclusions:Based on the combined analysis of DNA methylation and gene expression, a new idea of the occurrence and development of pulmonary embolism has been found, which can be further studied in the future.

RESUMO
2019 Novel coronavirus (2019-nCoV) infection caused a pandemic in the world. From the reported cases in the literatures, the level of D-dimer in patients with coronavirus disease 2019 (COVID-19) is positively correlated with the severity of illness, which needs the attention of clinical workers. According to Western medicine, the increase of D-dimer is related to the hyperactivity of fibrinolytic system and the shortening of prothrombin time (PT), resulting in excessive production and degradation of plasma fibrin and hypercoagulable state of blood, while traditional Chinese medicine (TCM) believes that the above syndromes belong to the pathogenesis of "blood stasis" according to TCM theories. Over the years, TCM has a significant effect on promoting blood circulation, removing blood stasis and improving microcirculation. This article reviews the mechanism, clinical significance, understanding of TCM and common methods of promoting blood circulation and removing blood stasis caused by 2019-nCoV, in order to provide ideas for the prevention and treatment of impaired blood coagulation in patients with COVID-19.
RESUMO
Objective To investigate the effects of desflurane on postoperative nausea and vomiting in patients undergoing gynecological laparoscopic surgery.Methods Patients who underwent gynecological laparoscopic surgery in the hospital from Dec.2016 to Nov.2017 were selected and divided into two groups,64 cases in the observation group and 68 cases in the control group.The observation group were treated by desflurane,and the control group were treated by desflurane combined with propofol.General information and intraoperative information of patients were collected.The time of eye opening,extubation,staying in postanesthesia care unit (PACU),postoperative stay were recorded.The incidence and severity of nausea and vomiting from 0 to 6 hours and 6 to 24 hours after surgery were also recorded.Results There was no significant difference in general information between the two groups such as anesthesia time,fluid input and total amount of opioids in operation (P> 0.05).The incidence and severity of PONV after surgery from 0 to 6 hours and 6 to 24 hours was similar (P> 0.05).The eye opening time,extubation time,staying time in PACU was meaningfully lower in observation group compared with control group(P<0.05),but the duration of hospitalization after surgery was insignificant(P>0.05).Conclusion Anesthesia with desflurane doesn't lead to more often or more severe nausea or vomiting,while it help patients wake up faster,which is worthy of clinical promotion.
RESUMO
Objective To develop an ideal hypertension combined hyperlipidemia(HP/HL)rat model by feeding spontaneously hypertensive rats(SHRs)with high fat diet, and to evaluate the pathological changes in target organs including heart and kidney. Methods Twenty 3-week old male SHRs were randomly divided into two groups: normal fat control group(SHR-NC)and high fat group(SHR-HF). Moreover,ten 3-week old male Wistar-Kyoto rats(WKY)were taken as the model control group(WKY-NC). The rats in SHR-HF group were fed with high-fat diet to induce HP/HL, while rats of WKY-NC and SHR-NC groups were fed with normal diet. The systolic blood pressure(SBP)and body weight were measured every week. At the end of the experiment, the rats were sacrificed to take serum samples for blood lipid analysis including high density lipoprotein(HDL-C), low density lipoprotein(LDL-C), total cholesterol(TC)and triglyceride(TG). Heart and kidney tissue samples were collected to examine the pathological changes using HE and Masson staining. Results Compared with the SHR-NC group, the SHRs fed with high-fat diet for 23 weeks presented significant increase of blood pressure and TC, TG, LDL-C, and decrease of HDL-C. The HP/HL rat model showed pathological changes in the HP/HL target organs, heart and kidney. Renal tissues were severely damaged and showed a large area of fibrosis. Besides, left ventricular hypertrophy and myocardial fibrosis were also observed. Conclusions A HP/HL rat model is successfully constructed by feeding SHRs with high-fat diet for 23 weeks. Most importantly,this model exhibits progressive renal and cardiac alterations, similar to those of patients with HP/HL. This HP/HL rat model may become widely used for evaluation of HP/HL therapeutic drugs.

RESUMO
Objective: To evaluate the potential dosimetric beneifts and optimal indications of intensity modulated radiation therapy (IMRT) and hybrid intensity modulated radiation therapy (Hybrid IMRT) for the left side breast cancer patients after breast-conservation therapy. Methods: Eight patients with left breast carcinoma who received breast-conservation surgery were selected for this study. Two plans were designed in 3-dimensional treatment planning system. The dose distributions of target volume and normal tissues, conformal index (CI) and heterogeneous index (HI) were analyzed by dose-volume histogram (DVH). Results: The PTV coverage was the same in the two radiotherapy plans. A better dose uniformity throughout the whole breast in Hybrid IMRT plan was achieved. The CI, the percentage of PTV receiving more than 105% prescribed dose (V105%), the percentage of PTV receiving more than 110% prescribed dose (V110%), and the Dmax, Dmin and Dmean of PTV were similar in the two plans. We compared the Hybrid IMRT with IMRT: V13of the ipsilateral lung decreased from 27.66% to 20.7%, V5 of the contralateral lung decreased from 8.01% to 2.25%, V10 and V20 of the heart decreased from 35.23% and 16.77% to 19.22% and 10.6% respectively, V5 and V10 of the contralateral breast decreased from 35% and 10.39% to 20.38% and 5.7% respectively, all with significant difference. V30 and V40 of the ipsilateral lung and V40 of the heart increased by 1.28%, 1.48%, and 2.48%, with signiifcant difference. Conclusion: Hybrid IMRT is a better choice for patients whose treatment position is inaccurate or cannot be repeated well.
RESUMO
Objective To investigate the significance of aldehyde dehydrogenase 1 (ALDH1)expression in appraising the prognosis of nasopharyngeal squamous carcinoma (NPC).Methods The expression of ALDH1 protein was detected by immunohistochemistry in human specimens obtained from 120 NPC patients without the history of radiotherapy or chemothetapy.Results A relatively high expression of ALDH1 were observed in 40.0 % (48/120) patients of NPC,the expression of ALDH1 in the edge of the cancer nests and stroma,particularly spindle cancer cells were strongly positive.The positive expression of ALDH1 was closely associated with patients' nasopharyngeal tumor size (P =0.011),lymphatic metastasis (P =0.005) and clinic stage (P =0.001),but not associated with their gender and age (both P > 0.05).The Kaplan-Merier and Cox regression analysis indicated that ALDH 1 closely correlated with clinical progrosis of the patients.It showed that ALDH1 was an independent risk factor which may affect the prognosis of NPC patients.Conclusion The expression of ALDH1 protein closely correlate with clinic outcome of NPC,suggesting that ALDH1 is a risk factor for clinic progrosis of NPC patients.
RESUMO
OBJECTIVE@#To observe the clinical results and the toxicities of normal tissues in untreated nasopharyngeal carcinoma (NPC) treated with intensity modulated radiation therapy (IMRT).@*METHODS@#A total of 90 patients with untreated NPC received IMRT. According to the 1992 Fuzhou staging system, 3 patients were in stage I, 29 in stage II, 26 in stage III, and 32 in stage IVa. For IMRT,the prescription dose was 71.94-77.88 Gy/33f for the planning target volume of the gross tumor volume in the nasopharynx (PGTVnx); 69.96 Gy/33f for the positive neck lymph nodes (GTVnd); 60-66 Gy/33f for the planning target volume of the high risk regions (PTV1); and 50.4-56 Gy/28f for the planning target volume of the low risk regions (PTV2). Chemotherapy included concurrent and adjuvant protocols. The overall survival rate, local control rate, and distant metastasis-free survival rate were estimated by Kaplan-Meier method. Cox regression was used for multivariate analysis. Acute and 1ate toxicities were graded according to RTOG radiation morbidity scoring criteria.@*RESULTS@#The median follow-up time was 33 months (12-56 months). The 1-, 2-, 3- and 4-year survival rate was 97.8%, 90.6%, 86% and 80%; the local control tate was 98.8%, 97.5%, 92.1% and 77.4%; and the distant metastasis-free survival rate was 95.3%, 90.7%, 88.4% and 85.8%, respectively. The most serious acute toxicity was irradiated inflammation of mocosa with Grade 1 to 4 of 16.7%, 60%, 23.3% and 0, respectively. In the multivariate analysis, clinical stages were the prognostic factors for the survival rate. The most serious toxicity was salivary gland. The rate of grade xerostomia 1-year after the radiotherapy with Grade 1 to 4 was 18.1%, 9.6%, 0 and 0, respectively.@*CONCLUSION@#IMRT combined chemotherapy can improve the survival rate, and late adverse reaction is obviously decreased. Local recurrence and distant metastasis are the main reasons for low survival rate.
