OBJECTIVETo investigate the effect of rosiglitazone on the expression of nuclear factor-kappaB (NF-kappaB) and coupling factor 6 (CF6) induced by tumor necrosis factor-alpha (TNF-alpha) in cultured human umbilical vein endothelial cells (HUVEC).

METHODSCultured HUVEC of passage 3-5 were stimulated with TNF-alpha and then cultured in the presence of rosiglitazone. The expression of CF6 and NF-kappaB subunit p65 were evaluated by immunocytochemistical method.

RESULTSPretreatment of HUVECs with rosiglitazone inhibited TNF-alpha-induced expression of CF6 in a dose-dependent manner. The activation of CF6 stimulated by TNF-alpha was suppressed by ROS in a dose-dependent manner.

CONCLUSIONTNF-alpha-induced enhancement of the gene expression and release of CF6 is mediated by activation of NF-kappaB signaling pathway. ROS can inhibit the activation of IKK, block NF-kappaB signaling pathway and inhibit the expression of CF6, which may be the mechanism underlying the action of TZDs on hypertension.

BACKGROUNDThe enlarged prostate leads to obstruction and lower urinary tract symptoms (LUTS), which comprise frequency, urgency, weak stream, straining and nocturia. This study was conducted in a large series of patients to evaluate the relationship between LUTS as stipulated in the International Prostate Symptom Score (IPSS) and the objective parameters related to benign prostatic hyperplasia (BPH).

METHODSWe enrolled 1295 BPH patients from seven centers. The patients were either at first diagnosis of BPH or had discontinued medical treatment for at least 3 months. Those with several other diseases that may be potential risk factors affecting urinary symptoms were excluded from the study. Age, IPSS, prostate volume, peak flow rate, urine volume and post-voiding residual urine volume were measured. The relationship between IPSS and objective parameters were quantified by means of Spearman correlation coefficients. The differences in these parameters between the groups with mild, moderate or severe symptoms were also evaluated.

RESULTSStatistically significant correlations were found between IPSS and objective parameters by means of Spearman correlation coefficients. When the patients were divided into three groups with different severities of symptoms, there were significant differences in peak flow rate, urine volume, prostate volume, residue urine volume and quality of life, whereas average age and prostate-specific antigen levels were similar. However, there was evident overlap of these parameters between the groups. The same results were found when the irritative or obstructive subscore of IPSS was considered.

CONCLUSIONSThe correlation between objective parameters of BPH and LUTS is significant. However, it is hard to predict the severity of symptoms by these parameters.

OBJECTIVETo investigate the effect and safety of zoledronic acid (Zoledex) in patients with cancer-induced hypercalcemia.

METHODSSeventeen patients with cancer-induced hypercalcemia (corrected blood calcium > 2.70 mmol/L) were treated intravenously by 4 mg zoledex within 15 minutes on the first day. The corrected blood calcium was observed every 4 days in the following 28 days.

RESULTSThe response rate was 94.1% (16/17). The mean corrected blood calcium became normal after the first dose of zoledex (P < 0.01). The lowest value was found on the fourteenth day after treatment. The main side effects consisted of fever (29.4%, 5/17), hypocalcemic tetany (11.8%, 2/17) and arythmia (5.9%, 1/17).

CONCLUSIONZoledex is effective and safe in the treatment of patient with cancer-induced hypercalcemia.

OBJECTIVETo compare the differences of the efficacy and different therapeutic drugs on the treatment of benign prostatic hyperplasia (BPH) in order to ensure the optimal indication for different BPH patients.

METHODSA randomized, parallel-controlled, multicenter clinical trial was conducted. From September 2002 to December 2003 906 BPH patients were enrolled into 7 therapeutic groups, including selective-adrenoceptor antagonist (terazosin, doxazosin tamsulosin and naftopidil), 5 alpha-reductase inhibitor (finasteride and epristeride) and natural product (cernilton). International Prostate Symptom Score (IPSS) and Quality of Life (QOL), uroflowmetry, total prostatic volume (TPV) and transitional zone volume and residual urine were used as efficacy criteria.

RESULTSAccording to the baseline, the IPSS and Qmax were significantly correlated to the prostatic volume and transitional zone volume (P < 0.01). At average follow-up of 6 months, significant improvements in IPSS, QOL, Qmax and residual urine volume were observed in each therapeutic group, and no difference in IPSS improvement was found among the groups. Prostatic volume and transitional zone volume were significant decreased in 5alpha-reductase inhibitor groups (P < 0.05). In patients with baseline TPV greater than 35.5 cm3, the improvement of Qmax was more significant than that in patients with TPV less than 35.5 cm3 in finasteride group (P < 0.01) (5.7 ml/s and 2.2 ml/s respectively), and more significant symptomatic improvements were also found in cernilton, doxazosin and naftopidil group. In each group, the improvement of symptom were more significant in patients with IPSS higher than 20 points (P < 0.01).

CONCLUSIONSEach drug observed in this study can improve the subjective and objective symptoms significantly for BPH patients, especially for patients with higher IPSS baseline. When using 5alpha-reductase inhibitor, prostatic volume can be decreased significantly and more obviously subjective and objective improvement can be found in the patients with TPV greater than 35.5 cm3.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.

Objective To investigate the prevalence of tension-type headache(TTH)in children and adolescents aged 0-19 years globally in 1990-2021,and to provide a basis for the prevention and treatment of TTH.Methods Based on the Global Burden of Disease Study data,the age-standardized prevalence distribution of TTH and its changing trend were analyzed among the children and adolescents aged 0-19 years,with different sexes,age groups,sociodemographic index(SDI)regions and countries/territories.Results The age-standardized prevalence rate(ASPR)of TTH in children and adolescents aged 0-19 globally in 2021 was 17 339.89/100 000,which was increased by 1.73%since 1990.The ASPR in females was slightly higher than that in males(1990:17 707.65/100 000 vs 16 403.78/100 000;2021:17 946.29/100 000 vs 16 763.09/100 000).The ASPR in adolescence was significantly higher than that in school-aged and preschool periods(1990:27 672.04/100 000 vs 10 134.16/100 000;2021:28 239.04/100 000 vs 10 059.39/100 000).Regions with high SDI exhibited a higher ASPR than the other regions,with significant differences in prevalence rates across different countries.From 1990 to 2021,there was a slight increase in global ASPR,with an average annual percentage change(AAPC)of 0.06%.Females experienced a smaller increase than males based on AAPC(0.04%vs 0.07%).There was reduction in ASPR in preschool and school-aged groups,with an AAPC of-0.02%,while there was a significant increase in ASPR in adolescence,with an AAPC of 0.07%.ASPR decreased in regions with low-middle and low levels of SDI,with an AAPC of-0.02%and-0.04%,respectively,while it increased in regions with middle SDI,with an AAPC of 0.24%.Conclusions There is a consistent increase in the ASPR of TTH in children and adolescents aged 0-19 years globally,with significant differences across sexes,age groups,SDI regions and countries/territories.

Background: In our previous paper, we demonstrated that Connexin 43 (CX43) was highly expressed in bladder cancer (BC) tissues. But the molecular mechanism about microRNAs (miRNAs) regulation upstream of CX43 in BC has not been well elucidated and remains to be further studied. MicroRNA-139-5p (miR-139-5p) is a tumor suppressor in progression of multifarious cancers including BC. Nevertheless, the underlying mechanisms of CX43/miR-139-5p in tumorigenesis of BC are still not well illustrated. The specific objective of our study was to inquiry the effect of CX43/miR-139-5p on BC progression and its underlying mechanism. Methods: The bioinformatics analysis softwares were applied to predict the miRNAs in the upstream of CX43. First, the expression levels of miR-139-5p in BC tissues (tumor) and paracancer tissues (normal) were investigated using the data from The Cancer Genome Atlas database. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the mRNA expression level of miR-139-5p in three human BC cell lines 5637, T24, ECV-304 and a human bladder epithelial immortalized cell line SV-HUC-1 (normal control). Then si-CX43, si-control, miR-139-5p mimic, and its negative control (NC) were transfected into BC cell line ECV-304. The relationship of miR-139-5p and CX43 was analyzed by dual-luciferase reporter assay. The qRT-PCR and Western blotting were used to test the mRNA and protein expression level of CX43. The proliferation of ECV-304 and T24 cells were examined by cell counting kit-8. The migration and invasion of ECV-304 cells were tested by transwell assay. To determine whether miR-139-5p would affect cell proliferation, migration and invasion by targeting CX43, we executed the rescue assay. The comparison between two groups was analyzed by Student’s t test, and comparisons among multiple samples were performed by oneway analysis of variance and a Bonferroni post hoc test. Results: The expression of miR-139-5p was remarkably down-regulated in BC tissues (tumor vs. normal, 2.286 ± 0.017 vs. 3.211 ± 0.034, t= 11.540, P < 0.0001) and cell lines (P < 0.01 in all BC cell lines). Besides, we also indicated that over-expression of miR-139-5p reduced the proliferation of ECV-304 (P = 0.001) and T24 cells (P = 0.005). Moreover, miR-139-5p over-expression weakened the invasion (P = 0.001) and migration (P = 0.001) of ECV-304 cells. Furthermore, the relative luciferase activity of CX43-wild type construct was distinctly lessened by up-regulation of miR-139-5p (miR-139-5p mimic NC vs. miR-139-5p mimic, 0.916 ± 0.063 vs. 0.356 ± 0.048, t = 7.085, P = 0.002), nevertheless the activity of CX43-mutant type construct was untouched (miR-139-5p mimic NC vs. miR-139-5p mimic, 0.918 ± 0.057 vs. 0.878 ± 0.039, t= 0.577, P = 0.595). Finally, the rescue assay revealed that CX43 deletion enhanced the depressor effect of miR-139-5p on ECV-304 cell proliferation (P < 0.01), invasion (P = 0.028), and migration (P = 0.014). Conclusion MiR-139-5p, as a tumor-suppressor, repressed cell proliferation, invasion, and migration in BC, which might be achieved by regulating CX43.
