Objective To investigate the effects of postoperative semi-reclining position in early stage on the comfort degree of patients with endoscopic sinus surgery under general anesthesia. Methods Totally 106 cases of patients with endoscopic sinus surgery under general anesthesia were selected from the ENT&HN Surgery Department of Beijing Tongren Hospital during September 2014 to May 2015. The patients were randomly divided into the control group (n=54) and the experimental group (n=52). Patients in the control group adopted traditional clinostatism after surgery,while patients in the experimental group adopted early semi-reclining position after surgery. Four hours after surgery,patients' comfort degree with discomfort visual analogue score (VAS) were evaluated,and the incidence of neck-shoulder soreness and waist soreness of patients was compared between two groups. Results In the experimental group,the total discomfort VAS score of patients was 3.00 (2.00~5.00),which was lower than VAS score 4.00 (3.00~6.00) in the control group (Z=-2.270,P<0.05). In the experimental group,the incidence of shoulder-soreness was 0,and the incidence of waist soreness was 3.85%,and they were all lower than those in the control group (16.67%,11.11%) (χ2= 9.471,5.666;P<0.05). Conclusions Early semi-reclining position can effectively reduce the postoperative headache,ear fullness and general discomfort of patients with endoscopic sinus surgery,reduce the occurrence of shoulder-neck soreness and waist soreness of patients,and improve patients' comfort.

Objective To investigate the degree of pain, pain control and influencing factors of patients with silicone drainage tube after endoscopic sinus surgery, so as to provide the basis for the management of pain and comfort nursing. Methods From March to August in 2016, 102 patients undergone endoscopic sinus surgery were selected as the research objects. They were treated with silicone drainage tube within 48 h after operation. The patient's pain status and its influencing factors were assessed by the Brief Pain Scale (BPI) at 24 h and 48 h after operation. Results In 24-48 h after surgery, the most degree of pain, the lightest degree of pain, the average degree of pain, the exist degree and the overall degree of pain were significantly reduced than those in 24 h after surgery,and the differences were statistically significant (t=3.446, 4.790, 5.413, 4.758, 5.374;P<0.05); In 24-48 h after the surgery, the pain impact on daily life, mood, work, sleep and overall effects were significantly reduced than those in 24 h after the surgery, and the differences were statistically significant (t=2.729, 2.912, 3.260, 2.080, 2.702; P <0.05); 24-48 h after operation, the overall pain state of patients with patient-controlled analgesia (PCA) (2.15±1.69) was significantly lower than that patients who did not receive the PCA (3.26±1.94), and the difference was statistically significant (t=2.871, P=0.005). Conclusions The pain nursing of the patients with silicone tube should not be neglected, especially in 24 h after surgery nurses should strengthen the assessment and management of pain, and pay attention to the impact of pain; For pain control, we should not use single control mode, but should focus on exploring various ways to control pain.

MicroRNAs (miRNAs) play critical roles in the development and progression in various cancers.Dysfunctional miR-9 expression remains ambiguous,and no consensus on the metastatic progression of ovarian cancer has been reached.In this study,results from the bioinformatics analysis show that the 3'-UTR of the E-cadherin mRNA was directly regulated by miR-9.Luciferase reporter assay results confirmed that miR-9 could directly target this 3'-UTR.miR-9 and E-cadherin expression in ovarian cancer tissue was quantified by qRTPCR.Migration and invasion were detected by wound healing and Transwell system assay in SKOV3 and A2780.qRT-PCR and Western blot were performed to detect the epithelial-mesenchymal transition-associated mRNA and proteins.Immunofluorescence technique was used to analyze the expression and subcellular localization of Ecadherin,N-cadherin,and vimentin.The results showed that miR-9 was frequently upregulated in metastatic serous ovarian cancer tissue compared with paired primary ones.Upregulation of miR-9 could downregulate the expression of E-cadherin but upregulate the expression of mesenchymal markers (N-cadherin and vimentin).Overexpression of miR-9 could promote the cell migration and invasion in ovarian cancer,and these processes could be effectively inhibited via miR-9 inhibitor.Thus,our study demonstrates that miR-9 may promote ovarian cancer metastasis via targeting E-cadherin and a novel potential therapeutic approach to control metastasis of ovarian cancer.

Tumor-associated tertiary lymphoid structures(TLSs)are ectopic lymphoid formations within tumor tissue,with mainly B and T cell populations forming the organic aggregates.The presence of TLSs in tumors has been strongly associated with patient responsiveness to immunotherapy regimens and improving tumor prognosis.Researchers have been motivated to actively explore TLSs due to their bright clinical application prospects.Various studies have attempted to decipher TLSs regarding their formation mechanism,structural composition,induction generation,predictive markers,and clinical utilization.Meanwhile,the scientific approaches to qualitative and quantitative descriptions are crucial for TLS studies.In terms of detection,hematoxylin and eosin(H&E),multiplex immunohistochemistry(mIHC),multiplex immunofluorescence(mIF),and 12-chemokine gene signature have been the top approved methods.However,no standard methods exist for the quantitative analysis of TLSs,such as absolute TLS count,analysis of TLS constituent cells,structural features,TLS spatial location,density,and maturity.This study reviews the latest research progress on TLS detection and quantification,proposes new directions for TLS assessment,and addresses issues for the quantitative application of TLSs in the clinic.

Malignancies are diseases resulting from an imbalance of cell growth and proliferation, endangering human health and life. Currently, there is no clinically effective treatment for tumors. Tumor cells may alter cell adhesion and tumor cell migration and movement by degrading the extracellular matrix, generating vascular factors, affecting epithelial-mesenchymal transformation, or altering the tumor microenvironment. The mechanisms which lead to multidrug resistance (MDR) are the regulation of membrane proteins, apoptosis-regulated gene expression, enzyme-mediated multidrug resistance, DNA damage repair, and epithelial-stromal transformation, resulting in ineffective treatment of tumors. Therefore, the search for natural, safe, and effective chemosensitizers has become a critical part in tumor research. Due to the increasing use of Chinese medicine in cancer treatment, researchers have conducted more extensive studies on its monomers and compounds. In addition, the mechanisms of Chinese medicine in inhibiting tumor invasion and metastasis and reversing drug resistance are gradually unraveled. The monomers and compounds of Chinese medicine may inhibit tumor invasion, metastasis, and drug resistance by enhancing the sensitivity of chemotherapy drugs and adjuvant properties. Furthermore, they can also improve the tolerance of patients to chemotherapy drugs, relieve side effects of chemotherapy, reduce the chance of recurrence, and prolong the life of patients. The development of traditional Chinese medicine plays an important role in reducing tumor recurrence and metastasis, reversing drug resistance, prolonging the prognosis of cancer patients, improving their quality of life, and prolonging their survival time. Currently, various types of Chinese medicines have been proven to be capable of reducing tumor invasion and metastasis, and reversing drug resistance. The present article reviewed development and findings of Chinese medicine as an anti-tumor invasion, anti-metastasis, and anti-tumor resistance therapy in recent years, in order to provide ideas for future research on anti-tumor effect of active components in Chinese medicine.
