ABSTRACT

Objective:To observe the efficacy of Qingre Lishi prescription in treating children with acute bacterial lower urinary tract infection of bladder damp-heat syndrome, and to explore its mechanism of action. Method:Eighty children with acute bacterial lower urinary tract infection of late bladder damp-heat syndrome who were admitted to the Affiliated Hospital of Changchun University of Chinese Medicine were divided into control group and observation group, 40 cases in each group. Patients in control group were given Bazhengsan for oral treatment on basis of basic treatment, while patients in observation group were given Qingre Lishi prescription for oral administration plus external washing treatment. After two weeks of treatment, the clinical and etiological effect, traditional Chinese medicine (TCM) syndrome scores, antipyretic time and urinary negative time, adverse reactions, and urine pathogens (<italic>Escherichia coli, Enterococcus faecalis, Strange proteus, Klebsiella pneumoniae</italic>), serum inflammatory factor indicators [tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), interleukin-6 (IL-6), interleukin-8 (IL-8), calcium lowering PCT, white blood cell count (WBC) and serum C-reactive protein (CRP)], immune function indicators [T cell subsets (CD3<sup>+</sup>, CD4<sup>+</sup>, CD8<sup>+</sup>) and complement (C3, C4)] were comapred between two groups. Result:The clinical efficacy of observation group was 92.50% (37/40), which was significantly higher than 65.00% (26/40) in control group (<italic>χ<sup>2</sup></italic>=9.038, <italic>P</italic><0.01), the etiological efficacy of observation group was 87.50% (35/40), which was significantly higher than 60.00% (24/40) in control group (<italic>χ<sup>2</sup></italic>=7.813, <italic>P</italic><0.01). After treatment, the scores of TCM syndromes of the two groups were significantly reduced (<italic>P</italic><0.05). The scores of fever, frequent urination, urgent urination, painful urination, difficulty urinating and abdominal pain in two groups were significantly lower than those before treatment (<italic>P</italic><0.05), and the TCM syndrome scores in observation group were lower than those in control group (<italic>P</italic><0.05), the antipyretic time and urinary bacteria turning negative time of observation group were significantly lower than those in control group (<italic>P</italic><0.05), the <italic>Escherichia coli, Enterococcus faecalis, Proteus mirabilis, Klebsiella pneumoniae</italic> pathogenic bacteria detected in both groups were both significantly lower than those before treatment (<italic>P</italic><0.05). After treatment, the levels of inflammatory factors such as TNF-<italic>α</italic>, IL-6, IL-8, PCT, WBC and CRP in two groups were significantly lower than those before treatment (<italic>P</italic><0.05), the immune function of the two groups was significantly improved, and the levels of CD3<sup>+</sup>, CD4<sup>+</sup>, C3, and C4 in observation group were higher than those in control group(<italic>P</italic><0.05), and the CD8<sup>+</sup> level was lower than that in control group (<italic>P</italic><0.05). The incidence of adverse reactions had no significant difference between two groups.

ABSTRACT

Background and purpose:As a tumor suppressor gene, ribosomal S6 kinase 4 (RSK4) plays important roles in inhibiting cell proliferation, migration and inducing cell apoptosis. However, the proteins interacting with RSK4 are still unknown. This study aimed to screen proteins interacting with RSK4 in breast cancer cell line MDA-MB-231 by lfag-tag affnity puriifcation and LC-MS/MS (liquid chromatography/mass spectrometry).Methods:The pcDNA3.1/EGFP-RSK4-Flag eukaryotic expression vector was constructed by inserting full lengthRSK4 gene into vector pcDNA3.1/EGFP-Flag. And then the recombinant plasmids were transferred into MDA-MB-231 cells. Real-timelfuorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot were used to detect the expression of RSK4 in MDA-MB-231 cells. Affnity puriifcation and LC-MS/MS were applied to screen proteins interacting with RSK4, and the related action mechanism of RSK4 with its interacted proteins was detected based on bioinformatics gene ontology (GO) and ingenuity pathway analysis (IPA).Results:Twenty-four proteins, such as serine/threonine-pro-tein kinase 38 (STK38)/serine/threonine-protein kinase 38-like (STK38L), MOB kinase activator 2 (MOB2) and protein arginineN-methyltransferase 5 (PRMT5), were successfully identiifed by Flag-tag affnity puriifcation followed by LC-MS/MS analysis, which probably interacted with RSK4. Bioinformatics analysis of the identiifed proteins suggested the proteins interacting with RSK4 were involved in diverse biological pathways, such as apoptosis and cell migration. Conclusion:According to bioinformatics results of proteins interacting with RSK4 identiifed by affnity puriifcation and LC-MS/MS, biological networks of RSK4 are involved in apoptosis and migration in breast cancer cells.

ABSTRACT

<p><b>OBJECTIVE</b>To determine the mechanism of pseudo-tears of the lateral meniscus caused by the transverse geniculate ligament (TL) and the miniscofemoral ligament(MFL) and to investigate a method to differentiate pseudo-tears from true tear of the lateral meniscus.</p><p><b>METHODS</b>Form June 2012 to February 2014, MR examinations of 72 knees (44 left knees and 28 right knees) without tear of the lateral meniscus verified by arthroscopy were performed in the sagittal and coronal plane. There were 41 males and 31 females in the group, with an average age of 33.7 years old (ranged from 25 to 61). The MR appearance of the TL and the MFL was carefully observed.</p><p><b>RESULTS</b>There existed fatty tissue in the gap between the TL and the anterior horn of the lateral meniscus and its central tendinous attachment. On the sagittal images, the fatty tissue formed a linear high-signal cleft between the TL and the anterior horn of the lateral meniscus. This might be mistaken as an oblique tear within the anterior horn of the lateral meniscus. It was called as pseudo-tears of the anterior horn of the lateral meniscus. In sagittal plane, the MFL was identified as a circle-like or short stick-like area of low signal intensity anterior or posterior to the posterior cruciateligament. Nevertheless, a belt-shaped area of low signal intensity from the posterior horn of the lateral meniscus to lateral facet of the medial femoral condyle was identified in the coronal plane. A linear area of high signal intensity between the MFL and the lateral meniscus was found in sagittal plane, which might be mistaken as an oblique tear within the posterior horn of the lateral meniscus. It was called pseudo-tears of the posterior horn of the lateral meniscus. The occurrence rate of the TL was 34.7% (25/72). The prevaleribe of pseudo-tears of the anterior horn of the lateral meniscus was 18 cases. The shape of the anterior horn of the lateral meniscus was regular, and the course of the pseudo-tears cleft was oblique. The occurrence rate of the MFL was 73.6% (53/72), which included the anterior MFL 23.6% (17/72), the posterior MFL 70.8% (51/72) and the two ligaments coexisted 16.7% (12/72). The prevalence of pseudo-tears of the posterior horn of the lateral meniscus was 25 cases. All observed pseudo-tears had either in posteroinferiorly oblique direction (19/25) or in vertical direction (6/25).</p><p><b>CONCLUSION</b>Based on the location and direction of pseudo-tears and observation in the continuous sagittal plane and the coronal plane, pseudo-tears is easily differentiated from the true tear of the lateral meniscus</p>
