ABSTRACT
Objective::To observe the clinical efficacy of modified Simiaosan on synovitis of knee joint with damp-heat obstruction collateral syndrome and the effect on inflammatory factors and neuropeptide substances in synovial fluid. Method::One hundred and thirty-five patients were randomly divided into control group(67 cases) and observation group(68 cases) by random number table. Patients' intra-articular effusion was drawn out. Triamcinolone acetonide was injected into arthrosis for 2 times, 1 time/week, and aceclofenac sustained-release tablets were given for 4 weeks, 0.2 g/time, 1 time/day. In addition to the therapy of control group, patients in observation group were also given modified Simiaosan for 4 weeks, 1 dose/day. Before and after treatment, pain, swelling of knee joint and were scored, Western Ontario and McMaster University (WOMAC) were adopted for scoring knee score, and damp-heat obstruction syndrome and local signs of knee joint were also assessed. And levels of interleukin-1 beta (IL-1 beta), IL-6, tumor necrosis factor-alpha (TNF-alpha), hypersensitive C-reactive protein (hs-CRP), substance P (SP), calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY) and vasoactive intestinal peptide (VIP) were detected. Result::After treatment, scores of pain and swelling of knee joint in observation group were lower than those in control group (P<0.01). Scores of WOMAC, the total score, integral of damp-heat obstruction collateral syndrome, knee flexion-extension range score and floating patella test were all lower than those in control group (P<0.01). And levels of IL-1β, IL-6, TNF-α, hs-CRP, SP, CGRP, NPY and VIP were all lower than those in control group (P<0.01). Analyzed by rank sum test, the clinical efficacy in observation group was better than those in control group (Z=2.089, P<0.05). Conclusion::Modified Simiaosan can significantly alleviate pain and swelling symptoms, promote the recovery of knee joint function, and inhibit the expressions of proinflammatory factors and neuropeptides in synovial fluid, with a better clinical efficacy.
ABSTRACT
Background@#Rapid visual acuity (VA) decline was a common complaint in patients with sellar/suprasellar germinoma. In our hospital, 3.4 Gy/2f of emergency irradiation was applied to save patient VA and enable subsequent chemoradiotherapy. This study aimed to investigate the efficacy of emergency irradiation with 3.4 Gy/2f in patients with sellar/suprasellar germinoma who had rapid VA decline.@*Methods@#From January 2014 to December 2017, 33 patients with sellar/suprasellar germinoma who complained of VA decline within 3 months received 3.4 Gy/2f of emergency irradiation in Beijing Tiantan Hospital. The best-corrected VA (BCVA) and mean deviation (MD) were measured. Correlations between visual function change and clinical factors, including age at diagnosis, duration of VA decline, extent of tumor regression, serum level of tumor markers, were analyzed.@*Results@#Among 33 patients with sellar/suprasellar germinoma, the median diameter and volume of sellar/suprasellar lesions were 32 mm (range: 5–55 mm) and 12.9 cm3 (range 0.6–58.5 cm3), respectively. Data on pre- and post-emergency-irradiation BCVA were obtained in 32 patients. For the right eyes, BCVA was improved in 23 patients (71.9%), unchanged in 7 (21.9%), and worsened in 2 (6.2%); and for the left eyes, these numbers were 27 (84.4%), 4 (12.5%), and 1 (3.1%), respectively. In terms of the logarithm of the minimum angle of resolution (logarithm of the minimum angle of resolution = Log (1/BCVA) score, the improvement was significant in both eyes (P < 0.001). In terms of MD, six patients had paired data and the improvement was marginal in the right eyes (P = 0.068) and significant in the left eyes (P = 0.043). However, no clinical factor was found to have correlation with visual function improvement.@*Conclusion@#In sellar/suprasellar germinoma patients with VA decline, 3.4 Gy/2f of emergency irradiation was effective in improving visual function.

ABSTRACT
<p><b>Background</b>The role of postradiation systemic therapy in non-small cell lung cancer (NSCLC) patients with brain metastasis (BM) was controversial. Thus, we explored the role of Radiation Therapy Oncology Group recursive partitioning analysis (RTOG-RPA) and graded prognostic assessment (GPA) in identifying population who may benefit from postradiation systemic therapy.</p><p><b>Methods</b>The clinical data of NSCLC patients with documented BM from August 2007 to April 2015 of two hospitals were studied retrospectively. Cox regression was used for multivariate analysis. Survival of patients with or without postradiation systemic therapy was compared in subgroups stratified according to RTOG-RPA or GPA.</p><p><b>Results</b>Of 216 included patients, 67.1% received stereotactic radiosurgery (SRS), 24.1% received whole-brain radiation therapy (WBRT), and 8.8% received both. After radiotherapy, systemic therapy was administered in 58.3% of patients. Multivariate analysis found that postradiation systemic therapy (yes vs. no) (hazard ratio [HR] = 0.361, 95% confidence interval [CI] = 0.202-0.648, P = 0.001), radiation technique (SRS vs. WBRT) (HR = 0.462, 95% CI = 0.238-0.849, P = 0.022), extracranial metastasis (yes vs. no) (HR = 3.970, 95% CI = 1.757-8.970, P = 0.001), and Karnofsky performance status (<70 vs. ≥70) (HR = 5.338, 95% CI = 2.829-10.072, P < 0.001) were independent factors for survival. Further analysis found that subsequent tyrosine kinase inhibitor (TKI) therapy could significantly reduce the risk of mortality of patients in RTOG-RPA Class II (HR = 0.411, 95% CI = 0.183-0.923, P = 0.031) or with a GPA score of 1.5-2.5 (HR = 0.420, 95% CI = 0.182-0.968, P = 0.042). However, none of the subgroups stratified according to RTOG-RPA or GPA benefited from the additional conventional chemotherapy.</p><p><b>Conclusion</b>RTOG-RPA and GPA may be useful to identify beneficial populations in NSCLC patients with BM if TKIs were chosen as postradiation systemic therapy.</p>

AIM:To investigate the effect of different cutting centers on the visual acuity, refractive diopter and visual quality of patients undergoing laser assisted in situ keratomileusis (LASIK).METHODS: A total of 80 patients (160 eyes) with myopia treated by elective LASIK were divided into two groups.Thirty-six cases (72 eyes) with visual axis corneal reflection point (VACRP) as the cutting center were included into the VACRP group while 44 cases (88 eyes) with pupil center (PC) as the cutting center were included into the PC group.The uncorrected visual acuity (UCVA), the best corrected visual acuity (BCVA), refractive diopter, corneal aberration [total corneal and anterior corneal surface higher-order aberrations (HOA), spherical aberration (Z40), vertical coma (Z3-1), horizontal coma (totZ31) and offset of cutting centers were determined before surgery and 1mo after surgery.RESULTS: There was no difference in the probability of UCVA ≥ 0.1, BCVA and refractive diopter between the two groups at 1mo after surgery (P>0.05).The astigmatism and cutting center deviation of VACRP group were lower than those of PC group (P<0.05).The totHOA, totZ40, totZ3-1, totZ31, froHOA, froZ3-1、froZ31 and froZ40 were lower in VACRP group than PC group at 1mo after surgery (P<0.05).CONCLUSION: The UCVA of patients treated with both cutting centers for LASIK is good but VACRP has more advantages in reducing the offset of cutting center and improving postoperative visual quality.
ABSTRACT
<p><b>BACKGROUND</b>For patients with a brain metastasis (BM), systemic therapy is usually administered after the completion of radiotherapy, especially in cases of multiple BMs. However, the role of systemic therapy in patients with a limited number of BMs is not clear. Therefore, we conducted a retrospective study to explore this question.</p><p><b>METHODS</b>Consecutive patients with a pathologically confirmed malignancy and 1-3 intracranial lesions that had been documented within the last decade were selected from the databases of three hospitals in China.</p><p><b>RESULTS</b>A total of 250 patients were enrolled; of them, 135 received radiotherapy alone and 115 received radiotherapy plus systemic therapy. In patients receiving whole-brain radiation therapy (WBRT) as radiotherapy, 28 received WBRT alone and 35 patients received WBRT plus systemic therapy. Of the patients treated with stereotactic radiosurgery (SRS), 107 received SRS alone and 80 received SRS plus systemic therapy. Multivariate analysis revealed that systemic therapy significantly reduced the risk of mortality compared with radiotherapy alone (hazard ratio [HR] = 0.294, 95% confidence interval [CI] = 0.158-0.548). Further, when the analysis was conducted in subgroups of WBRT (HR = 0.230, 95% CI = 0.081-0.653) or SRS (HR = 0.305, 95% CI = 0.127-0.731), systemic therapy still showed the ability to reduce the risk of mortality in patients with BMs.</p><p><b>CONCLUSION</b>Systemic therapy after either SRS or WBRT radiotherapy may significantly reduce the risk of mortality of patients with 1-3 BMs.</p>
ABSTRACT
Objective: To investigate the effect of miR-219-5p on malignant phenotype of glioblastoma cells involving proliferation, apoptosis and invasion, and to preliminarily determine the candidate target genes of miR-219-5p related to the inhibition of cancer. Methods: The inverse relationship between mRNAs and miR-219-5p in glioblastoma tissues from sixty cases was obtained by analysis of miR-219- 5p expression level and mRNA expression profiling. DAVID software for functional analysis was employed to analyze the functions of the top 50 mRNAs and screen out two sets of mRNAs related to glioblastoma progression. The target genes of miR-219-5p were screened out from the two sets of miRNAs on four websites of online target-binding prediction. MTT assay, flow cytometry (FCM) assay and Transwell assay were performed to detect the effects of miR-219-5p on the proliferation, apoptosis and invasion of human glioblastoma cells, respectively. Results: Fourteen proliferation/apoptosis-related genes and five invasion-related genes were screened from glioblastoma tissues of sixty patients (P <0.001). Four genes including TWIST 1, MYO 1B , WEE 1 and SPRED 2 were predicted as potential target genes of miR-219-5p from 19 candidate genes. Functional analysis revealed that miR-219-5p could suppress the proliferation and invasion of glioblastoma cells as well as promote the apoptosis (P <0.05). Conclusion: MiR-219-5p may suppress the malignant phenotype of glioblastoma cells through multiple gene targets. © 2012 by Tumor.
ABSTRACT
<p><b>BACKGROUND</b>Everlasting cellular proliferation is the fundamental feature during gliomagenesis and Ki-67 is one of the classical proliferation markers in human glioblastoma multiforme (GBM). However, the driver genes or core pathways for cellular proliferation in GBM have not been elucidated systematically.</p><p><b>METHODS</b>We evaluated by immunohistochemistry the prognostic value of Ki-67 expression in the clinical outcome of 156 Chinese patients with GBM and a total of 64 GBM samples were selected for further Agilent genome-wide microarray analysis. On the basis of the microarray data from Tiantan (n = 64) and The Cancer Genome Atlas (TCGA) (n = 202) database, differentially expressed genes between the GBM subgroups with high or low level of Ki-67 expression were identified using Significance Analysis of Microarrays (SAM). Gene Ontology (GO) and KEGG Pathway analyses were then undertaken for the Ki-67 associated genes to identify the most significant biological processes and signaling pathways.</p><p><b>RESULTS</b>We confirmed that Ki-67 was an independent prognostic indicator in the largest Chinese patient cohort of 156 GBM samples via immunohistochemical staining. Survival analysis of Ki-67 over-expression revealed a highly significant association with a worse clinical outcome (P = 0.010 for progression-free survival; P = 0.007 for overall survival). Comparative and integrated analysis between Tiantan and TCGA database identified a 247-gene "proliferation signature" (205 up-regulated and 42 down-regulated genes) that distinguished Ki-67 expression phenotypes. GO and KEGG Pathway analyses further indicated that Ki-67 expression phenotype was associated with distinct changes in gene expression associated with the regulation of cellular growth and proliferation.</p><p><b>CONCLUSIONS</b>Proliferation marker Ki-67 is an independent prognostic indicator in Chinese GBM patients. And Ki-67 associated proliferation signature identified through genome-wide microarray analysis may provide potential targets for anti-proliferation therapy in GBM.</p>
