ABSTRACT

The cases of feeling comfort during acupuncture and moxibustion treatment in literature were summarized and its biological basis was explored. A simple classification of comfort was made, and the importance of obtaining comfort in acupuncture treatment was pointed out. Considering the pursuit of less pain and harmlessness in modern clinical treatment, sugar needle should be advocated and popularized in current clinical practice of acupuncture and moxibustion.

ABSTRACT

To analyze the differentially expressed genes related to the chemosensitivity with the TPF regimen for hypopharyngeal squamous cell carcinoma and to measure potential functional targeting genes expressions. Twenty-nine patients with primary hypopharyngeal cancer who underwent induction chemotherapy with TPF from January 2013 to December 2017 in Beijing Tongren Hospital were enrolled for microarray analysis, including 28 males and 1 female, aged from 43 to 73 years old. Among them, 16 patients were sensitive to chemotherapy while 13 patients were non-sensitive. Illumina Human HT-12 Bead Chip was applied to analyze the gene expressions and online bioinformatics analysis was used to analyze the differentially expressed genes. Reverse transcription and quantitative real-time PCR (RT-qPCR) was used to measure the mRNA expression of potential functional genes of TPF induction chemotherapy in 43 samples, 29 from original patients and 14 from additional patients. Graphpad prism 7.0 software was used for statistical analysis. A total of 1 381 significantly differentially expressed genes were screened out. By GO analysis, up-regulated genes included sequestering in extracellular matrix, chemokine receptor binding and potassium channel regulator activity; down-regulated genes included regulation of angiogenesis, calcium ion binding and natural killer cell activation involved in immune response. With KEGG database analysis, down-regulated pathways included ECM-receptor interaction and peroxisome and up-regulated pathways included Glutathione metabolism and PPAR signaling pathway. The expressions of CD44 and IL-6R were significantly different and appeared biologically significant. CD44 was significantly upregulated in insensitive tissues (0.54±0.06) compared with sensitive tissues (0.33±0.04)(0.01). IL-6R was significantly downregulated in insensitive tissues (0.44±0.03) compared with sensitive tissues. (0.68±0.03) (0.01). CD44 and IL-6R may be potentially functional genes of TPF induction chemotherapy in hypopharyngeal squamous cell carcinoma.

ABSTRACT

BACKGROUND@#Long non-coding RNAs (lncRNAs) play key roles in human cancers. In our previous study, we demonstrated that lncRNA FKBP prolyl isomerase 9 pseudogene 1 (FKBP9P1) was highly expressed in head and neck squamous cell cancer (HNSCC) tissues. However, its functional significance remains poorly understood. In the present study, we identify the role and potential molecular biologic mechanisms of FKBP9P1 in HNSCC.@*METHODS@#Quantitative real-time polymerase chain reaction was used to detect the expression of FKBP9P1 in HNSCC tissues, matched adjacent normal tissues, human HNSCC cells (FaDu, Cal-27, SCC4, and SCC9), and human immortalized keratinocytes cell HaCaT (normal control). Cal-27 and SCC9 cells were transfected with sh-FKBP9P1-1, sh-FKBP9P1-2, and normal control (sh-NC) lentivirus. Cell counting kit-8 assay, colony formation assay, wound healing assay, and trans-well assay were used to explore the biologic function of FKBP9P1 in HNSCC cells. Furthermore, western blotting was used to determine the mechanism of FKBP9P1 in HNSCC progression. Chi-squared test was performed to assess the clinical significance among FKBP9P1 high-expression and low-expression groups. Survival analyses were performed using the Kaplan-Meier method and assessed using the log-rank test. The comparison between two groups was analyzed by Student t test, and comparisons among multiple samples were performed by one-way analysis of variance and a Bonferroni post hoc test.@*RESULTS@#FKBP9P1 expression was significantly up-regulated in HNSCC tissues (tumor vs. normal, 1.914 vs. 0.957, t = 7.746, P < 0.001) and cell lines (P < 0.01 in all HNSCC cell lines). Besides, the median FKBP9P1 expression of HNSCC tissues (1.677) was considered as the threshold. High FKBP9P1 level was correlated with advanced T stage (P = 0.022), advanced N stage (P = 0.036), advanced clinical stage (P = 0.018), and poor prognosis of HNSCC patients (overall survival, P = 0.002 and disease-free survival, P < 0.001). Knockdown of FKBP9P1 led to marked repression in proliferation, migration, and invasion of HNSCC cells in vitro (P all < 0.01). Mechanistically, silencing FKBP9P1 was observed to restrain the PI3K/AKT signaling pathway.@*CONCLUSIONS@#Silencing lncRNA FKBP9P1 represses HNSCC progression and inhibits PI3K/AKT (phosphatidylinositol 3 kinase/AKT Serine/Threonine Kinase) signaling in vitro. Therefore, FKBP9P1 could be a potential new target for the diagnosis and treatment of HNSCC patients.

ABSTRACT

The purpose of the present study was to investigate the effect of advanced glycated albumin (AGE-alb) on pyroptosis of macrophages and the underlying molecular mechanisms. RAW264.7 macrophages were treated with AGE-alb (1, 2, 4 and 6 g/L) and control albumin (C-alb, 4 g/L) for 24 h, or preincubated with MCC950 (1 μmol/L) for 1 h and then treated with AGE-alb (4 g/L) for 24 h. Cell viability and caspase-1 activity were measured by MTT and assay kits, respectively. Lactate dehydrogenase (LDH) activity and the levels of interleukin-1β (IL-1β) and IL-18 in media were detected. Cell death degree was evaluated by TUNEL and Hoechst 33342/PI staining. The protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), procaspase-1 and cleaved caspase-1 were assessed by Western blot. The results showed that AGE-alb treatment caused obvious decrease in cell viability and increases in LDH leakage and the percentages of TUNEL- or PI-positive cells in a concentration-dependent manner. Additionally, AGE-alb promoted IL-1β and IL-18 secretion, upregulated NLRP3 expression, and increased caspase-1 activity especially at the dose of 4 and 6 g/L. However, MCC950 (an NLRP3 inhibitor) pretreatment inhibited significantly the decrease in cell viability and the increases in LDH leakage and percentages of TUNEL- or PI-positive cells induced by AGE-alb. Furthermore, MCC950 attenuated obviously AGE-alb-induced IL-1β and IL-18 secretion and caspase-1 activation. These results indicate that AGE-alb may induce macrophage pyroptosis, and the mechanism is at least partially by activating NLRP3-caspase-1 pathway.

ABSTRACT

OBJECTIVE@#To survey the cigarette smoking status and periodontal status, and to study the correlation between cigarette smoking and periodontal status.@*METHODS@#Questionnaires were distributed (including self-assessed periodontal status, such as bleeding while brushing teeth, oral odor, tooth loosening, gum swelling, etc.) and clinical periodontal examinations performed for parameters including probing depth (PD), bleeding index (BI), attachment loss (AL), plaque index (PLI) and amount of teeth loss, which was recorded in the population above 35 years of a community in Beijing. A total of 974 subjects were recruited in the study. The population was divided into current smokers and non-smokers, and the differences of self-assessed periodontal status and periodontal parameters between the groups analyzed.@*RESULTS@#The smokers had significantly less bleeding during toothbrushing, and in the meantime, had significantly more self-reported tooth loosening compared with the non-smokers. The smokers brushed their teeth less than the non-smokers (P<0.05). The self-reported gum swelling and oral odor had no significant difference between the smokers and non-smokers. The smokers had 0.565 times and 1.572 times the risk of bleeding during toothbrushing, self-reported tooth loosening and from Logistic regression analyses, respectively (P<0.05). The mean PD, AL, PLI and the amount of tooth loss of the smokers were significant higher than the non-smokers (P<0.05). However, the mean BI of the smokers was slightly less than the non-smokers' (1.93±0.540 vs. 1.94±0.512, P=0.707). The smokers had 2.129 times, 1.698 times and 1.933 times the risk of the mean PD>3 mm, the mean AL>3 mm, and the amount of tooth loss above 8, respectively compared with the non-smokers (P<0.05) from Logistic regression analyses.@*CONCLUSION@#The self-assessed periodontal status is different between smokers and non-smokers in the population of a community in Beijing. Smokers have less bleeding during toothbrushing but no significant difference with BI. Smokers also have more self-reported tooth loosening. Compared with non-smokers, smokers have more severe periodontal destruction.

ABSTRACT

Objective To study the relationship between adolescent scoliosis and various biomechanical factors. Methods A total of 637 students in grade four to six in a primary school of Zhaoyang District in Zhaotong,Yunnan,Chi-na were screened for scoliosis in December,2016.Finally,a case control study of 19 patients with idiopathic sco-liosis who had been diagnosed by X-ray was carried out.According to the matching criteria,42 students were col-lected as control group.Then,eleven biomechanical factors were analyzed and evaluated in two groups.Those factors included unequal shoulders,cervical lateral flexion,cervical rotation,thoracic lateral flexion,thoracic ro-tation,lumbar lateral flexion,lumbar rotation,lateral tilt of pelvis,anterior and posterior pelvic tilt,leg inequality and flat foot. Eventually, the biomechanical factors were statistically analyzed with binary Logistic regression analysis. Results and Conclusion The unequal shoulders,thoracic rotation,lateral tilt of pelvis,leg inequality and flat foot were the risk factors for scoliosis(P<0.05).Detailed posture assessment should be carried out to find the biomechani-cal factors leading to abnormal posture,and achieve the goals of the more targeted medical intervention for the patients with spinal asymmetry.
