Open Versus Laparoscopic Inguinal Herniotomy in Children

Shaoguang Feng, Lingling Zhao, Zhenqi Liao, Xiaoming Chen
2015 Surgical laparoscopy, endoscopy & percutaneous techniques  
Purpose: There is an ongoing debate about whether laparoscopic or open herniorrhaphy (LH or OH) is the best choice for inguinal hernia in children. The aim of this study was to compare both of the surgical strategies as regards operative time, recurrence rate, postoperative complications by means of a systematic review, and meta-analysis of the available literatures. Methods: A systematic search for randomized clinical trials comparing OH and LH was conducted. Studies were reviewed for quality,

Results: Five randomized clinical trials with a total of 553 children (OH 278, LH 275) fulfilled the inclusion criteria and were analyzed in this review. Compared with OH, shorter operative time for unilateral hernias was noted in extraperitoneal approaches' group [95% confidence interval (CI), À 6.71 to À3.71; I 2 = 0%] as well as for bilateral hernias (95% CI, À 12.18 to À 3.79; I 2 = 82%). Besides, less total postoperative complications was found in LH group, especially for major postoperative complications in male children (95% CI, 0.01-0.78; I 2 = 0%). However, no significant difference was observed between LH and OH in patients' recurrence. Conclusions: This meta-analysis favors LH in the repair of bilateral hernias and for unilateral hernias in extraperitoneal approaches' group. Total postoperative complications were significantly reduced in LH, especially for major postoperative complications in male children. A B FIGURE 2.

Analysis of Cultural Meme Characteristics for Big Data of Cultural Relics

Haifeng Li, Zuoqin Shi, Li Chen, Zhenqi Cui, Sumin Li, Ling Zhao
2020 Information  
The cultural meme is the smallest unit constituting a dynasty′s culture, which has the same inheritance and variability as biological genes. Here, based on the name of cultural relics, we extract cultural memes through semantic word segmentation, word frequency statistics, and the synonym merging method, and construct dynasty cultural meme vectors. We analyzed color, auxiliary, texture, shape, and overall networks of five types of model to construct the culture network, using the social network

The main conclusions are as follows: (1) Cultural memes represent different cultural characteristics of dynasties, and the inheritance and differences among dynasties' cultures are closely related to their historical background. (2) Prevalence memes construct the cultural label of dynasties, which can roughly restore the cultural appearance of dynasties through fewer prevalence memes. (3) The use of community detection with a cultural meme network can determine the clustering of dynasties′ cultures, and the degree of centrality further reflects the main cultural characteristics presented by successive dynasties.

2004 Journal American Society of Mining and Reclamation  
Reclaimed land usually has some problems such as poor soil structure and nutrients shortage. The man-made improvement treatments could accelerate soil development of reclaimed soil and increase soil productivity. This study was conducted to determine the effectiveness of soil improvement with fly ash and organic fertilizer for reclaimed subsided land. A 0.23 ha of experimental site was chosen in Jiawang coal mining area, Jiangsu province, and 6 treatments were used in the design with 3 types of

The results showed that the application of fly ash could improve the reclaimed soil, but the amount of the fly ash should be more than 1%. The treatment of 1% fly ash had the lowest yield of soybeans, even lower that of the reference plot. As fly ash has fewer nutrients, some organic fertilizers are needed for higher yield. The treatment with 5% fly ash with poultry litter had the highest yield of soybeans. All the treatments of soil amendments were lower or equal to the concentrations of metal elements found for the control plot. The addition of organic fertilizer (D, E, F treatments) resulted significant decreases in the concentrations of Zn and Cu in the soybeans while the addition of 5% fly ash had only a slight decrease of the concentration of Zn and Cu in the beans. The pH and available nutrient contents of soils after harvest of the soybean were not affected by the application of fly ash.

Molecular Mechanism of Thiazolidinedione-Mediated Inhibitory Effects on Osteoclastogenesis

Dongfeng Zhao, Zhenqi Shi, Amy H. Warriner, Ping Qiao, Huixian Hong, Yongjun Wang, Xu Feng, Jean-Marc Vanacker
2014 PLoS ONE  
Thiazolidinediones are synthetic peroxisome proliferator-activated receptor c agonists used to treat type 2 diabetes mellitus. Clinical evidence indicates that thiazolidinediones increase fracture risks in type 2 diabetes mellitus patients, but the mechanism by which thiazolidinediones augment fracture risks is not fully understood. Several groups recently demonstrated that thiazolidinediones stimulate osteoclast formation, thus proposing that thiazolidinediones induce bone loss in part by

Moreover, the molecular mechanism by which thiazolidinediones modulate osteoclastogenesis is not fully understood. Here we independently address the role of thiazolidinediones in osteoclastogenesis in vitro and furthermore investigate the molecular mechanism underlying the in vitro effects of thiazolidinediones on osteoclastogenesis. Our in vitro data indicate that thiazolidinediones dose-dependently inhibit osteoclastogenesis from bone marrow macrophages, but the inhibitory effect is considerably reduced when bone marrow macrophages are pretreated with RANKL. In vitro mechanistic studies reveal that thiazolidinediones inhibit osteoclastogenesis not by impairing RANKLinduced activation of the NF-kB, JNK, p38 and ERK pathways in bone marrow macrophages. Nonetheless, thiazolidinediones inhibit osteoclastogenesis by suppressing RANKL-induced expression of NFATc1 and c-Fos, two key transcriptional regulators of osteoclastogenesis, in bone marrow macrophages. In addition, thiazolidinediones inhibit the RANKL-induced expression of osteoclast genes encoding matrix metalloproteinase 9, cathepsin K, tartrate-resistant acid phosphatase and carbonic anhydrase II in bone marrow macrophages. However, the ability of thiazolidinediones to inhibit the expression of NFATc1, c-Fos and the four osteoclast genes is notably weakened in RANKL-pretreated bone marrow macrophages. These in vitro studies have not only independently demonstrated that thiazolidinediones exert inhibitory effects on osteoclastogenesis but have also revealed crucial new insights into the molecular mechanism by which thiazolidinediones inhibit osteoclastogenesis.

Genetic Ablation of CD68 Results in Mice with Increased Bone and Dysfunctional Osteoclasts

Jason W. Ashley, Zhenqi Shi, Haibo Zhao, Xingsheng Li, Robert A. Kesterson, Xu Feng, Paul McNeil
2011 PLoS ONE  
CD68 is a member of the lysosome associated membrane protein (LAMP) family that is restricted in its expression to cells of the monocyte/macrophage lineage. This lineage restriction includes osteoclasts, and, while previous studies of CD68 in macrophages and dendritic cells have proposed roles in lipid metabolism, phagocytosis, and antigen presentation, the expression and function of CD68 in osteoclasts have not been explored. In this study, we investigated the expression and localization of

We found that M-CSF stimulates CD68 expression and RANKL alters the apparent molecular weight of CD68 as measured by Western immunoblotting. In addition, we explored the significance of CD68 expression in osteoclasts by generating mice that lack expression of CD68. These mice have increased trabecular bone, and in vitro assessment of CD68 2/2 osteoclasts revealed that, in the absence of CD68, osteoclasts demonstrate an accumulation of intracellular vesicle-like structures, and do not efficiently resorb bone. These findings demonstrate a role for CD68 in the function of osteoclasts, and future studies will determine the mechanistic nature of the defects seen in CD68 2/2 osteoclasts.

Up-regulation of LncRNA UCA1 by TGF-β promotes doxorubicin resistance in breast cancer cells

Like Wo, Bei Zhang, Xiongbin You, Yuanyuan Hu, Zhenqi Gu, Mengning Zhang, Qi Wang, Zhengyi Lv, Hong Zhao
2022 figshare.com  
Doxorubicin (DOX) resistance remains a major challenge for adriamycin-based treatment of breast cancer (BC). Transforming growth factor β (TGF-β) has been reported to contribute to drug resistance. Although the role of long noncoding RNAs (LncRNAs) in cancer progression has been widely studied, its effect on TGF-β-induced resistance remains limited. This study aimed to investigate the role of LncRNA on the regulation of TGF-β-induced drug resistance. Cell counting kit-8 (CCK-8) and an EdU assay
more » ... were used to evaluate cell viability and proliferation. The level of LncRNA mRNA expression in BC tissues and cells was examined by quantitative real-time PCR. Changes in epithelial-mesenchymal transition (EMT) and cell apoptosis were quantified by Western blot and immunofluorescence. TGF-β induced EMT and promoted DOX resistance. LncRNA urothelial carcinoma-associated 1(lncRNA UCA1) associated with TGF-β was upregulated in BC cells and tissues. LncRNA UCA1 silencing enhanced sensitivity to DOX decreased cellular proliferation and increased apoptosis in BC cells. The effect of TGF-β on EMT and DOX resistance disappeared following a lncRNA UCA1 knockdown. These findings suggest that lncRNA-UCA1, a mediator of TGF-β signaling, could predispose BC patients to EMT and DOX resistance.
