The effects of GK and KTM were determined by assessing the levels of cytokines in serum, and parameters of oxidative stress and ROS production in the intestinal tissues of I/R rats. Moreover, intestinal mRNA expressions of JNK, ERK, p38 and NF-kB were determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR).</p> <p><strong>Results</strong>: GK and KTM treatments, alone and in combination, reduced cytokine levels in serum and oxidative stress parameters in intestinal tissues, when compared to I/R group of rats. Treatments with GK and KTM, alone and in combination, mitigated the altered mRNA expressions of JNK, ERK, p38 and NF-kB in intestinal tissues of I/R-injured rats.</p> <p><strong>Conclusion</strong>: These results reveal that GK potentiates the protective effect of KTM100 on I/R-induced intestinal injury in rats by regulating the NF-kB/ERK/JNK signaling pathway. Therefore, GK and KTM may find use in the management of I/R</p> <p><strong>Keywords</strong>: Ginkgolide K, Ketamine, Intestinal injury, Ischemia/Reperfusion, Inflammation </p> Weina Zhu, Zhili Zhao, Xiongtao Liu, Xiumei Ni, Xiaoming Lei, Xiaoying Li, Rui Deng, Liyan Zhao Copyright (c) https://www.ajol.info/index.php/tjpr/article/view/204744 Wed, 17 Mar 2021 00:00:00 +0000 Leonurusine hydrochloride promotes osteogenic differentiation via Wnt/β-catenin pathway and expression of Runx2 https://www.ajol.info/index.php/tjpr/article/view/204746 <p><strong>Purpose:</strong> To investigate the effect of leonurusine hydrochloride (LH) on osteogenic differentiation, and the involvement of Wnt/β-catenin route and runt-associated transcription factor 2 (Runx2) in the process.</p> <p><strong>Methods</strong>: Mouse osteogenic precursor cell line MC3T3-E1 was used. The cells were assigned to control and three other groups treated with increasing doses of LH, i.e., 0.1, 1, and 10 μmmol/L. Cellular differentiation was determined in the various groups with respect to mRNA expressions of alkaline phosphatase (ALP), number of calcified nodules, Wnt/β-catenin pathway-related genes, viz, 5 (LRP5),<br>β-catenin, GSK-3β, as well as mRNA expressions of related osteogenic differentiation genes, namely. alkaline phosphatase (ALP), alpha 1 type I collagen (Col1-α), Run×2, and osteogenic-related transcription factor antibody (Osterix) using reverse transcription polymerase chain reaction (RT-PCR).</p> <p><strong>Results:</strong> The secretion levels of ALP in cells exposed to LH doses of 1 and 10 μmmol/L were significantly increased, relative to control values (p &lt; 0.05). There were marked increases in mRNA levels of LRP5 and β-catenin in cells treated with LH doses of 1 and 10 μmmol/L compared with the control group, while GSK-3β mRNA expression levels were significantly lower than that in control group<br>(p &lt; 0.05). However, the expression levels of ALP, Col1-α, Run×2, Osterix mRNA in cells exposed to LH at doses of 1 and 10 μmmol/L were significantly higher than the corresponding expression levels in control cells (p &lt; 0.05).</p> <p><strong>Conclusion</strong>: Leonurusine hydrochloride may promote osteogenic differentiation and bone mineralization via a mechanism involving activation of the Wnt/β-catenin pathway and up-regulation of Run×2 expression.</p> <p><strong>Keywords</strong>: Leonurusine hydrochloride, Wnt/β-catenin, Runx2, Osteogenic differentiation </p> Xiaobo Chen, Xiaoyu Lai, Xiaoyon Sun, Maoyuan Wang, Yu Cai Copyright (c) https://www.ajol.info/index.php/tjpr/article/view/204746 Wed, 17 Mar 2021 00:00:00 +0000 Downregulation of FOXO4 promotes neuronal survival by mediating oxidative-stress–induced apoptosis after cerebral ischemia/reperfusion injury https://www.ajol.info/index.php/tjpr/article/view/204747 <p><strong>Purpose</strong>: To investigate the effect of FOXO4 on cerebral ischemia/reperfusion (CIR) injury and the underlying mechanism.<br><strong>Methods</strong>: An in vitro ischemia/reperfusion (IR) model was achieved using oxygen-glucose deprivation/reoxygenation (OGD/R). Expression of RNA and protein was determined using quantitative real time polymerase chain reaction (qRT-PCR) and western blotting, respectively. Cell viability and apoptosis were determined using MTT assay and flow cytometry, respectively. Commercial kits were used to measure lactate dehydrogenase (LDH), reactive oxygen species (ROS), chloramphenicol acetyltransferase (CAT), malondialdehyde (MDA), and superoxide dismutase (SOD).<br><strong>Results</strong>: Following OGD/R, FOXO4 mRNA and protein expressions were upregulated in SH-SY5H human neuroblastoma cells. ODG/R reduced cell proliferation and increased the proportion of apoptotic cells, and these effects were inhibited by knockdown of FOXO4 (p &lt; 0.05). Levels of cleaved caspase 3 and cleaved poly(ADP-ribose) polymerases (PARPs) were increased after ODG/R and these increases<br>were inhibited by FOXO4 knockdown. ROS content and levels of LDH and MDA were increased after ODG/R and decreased by knockdown of FOXO4 (p &lt; 0.05). Levels of CAT and SOD were reduced after ODG/R, and this reduction was reversed by knockdown of FOXO4 (p &lt; 0.05).<br><strong>Conclusion:</strong> The results demonstrate that knockdown of FOXO4 promotes cell proliferation and inhibits cellular apoptosis via reduction of oxidative stress after CIR injury, indicating a new therapeutic target for the treatment of CIR injury.</p> <p><strong>Keywords:</strong> FOXO4, Neuronal survival, Oxidative stress, Cerebral ischemia/reperfusion injury</p> Chunying Deng, Peilan Zhang, Yun Zhang Copyright (c) https://www.ajol.info/index.php/tjpr/article/view/204747 Wed, 17 Mar 2021 00:00:00 +0000 Mir-23b down-regulates the expression of target gene of acetaldehyde dehydrogenase 1a1 and increases the sensitivity of cervical cancer stem cells to cisplatin https://www.ajol.info/index.php/tjpr/article/view/204748 <p><strong>Purpose</strong>: To study the effect of miR-23b on the expression of the target gene of acetaldehyde dehydrogenase 1A1 (ALDH1A1), and cisplatin (CDDP) susceptibility of cervical carcinoma stem cells.</p> <p><strong>Methods</strong>: Human cervical cancer cell line Hela cells were cultured in vitro, and miR-23b mimic and negative control were transfected into the cells using lipofectamine method. The growth of the two groups of cells was determined using growth curve method, and their proliferation measured using plate clone formation. The influence of treatments on the sensitivity of the cells to CDDP was assayed using MTT method. The mRNA expression of ALDH1A1 in Hela cells was assayed using real-time quantitative polymerase hain reation (PCR), while its protein expression was assayed by Western blot.</p> <p><strong>Results</strong>: The levels of expressions of ALDH1A1 protein and mRNA in the miR-23b overexpression group were significantly lower than those in the control group (p &lt; 0.05). The sensitivities of Hela cells to CDDP in the ALDH1A1 inhibition group and the control group were dose-dependent to some extent, but cell inhibition in ALDH1A1 inhibition group markedly increased, relative to control when the CDDP dose was 0.1 ppc (p &lt; 0.01).</p> <p><strong>Conclusion</strong>: Up-regulating the expression of miR-23b significantly inhibits the growth and proliferation of cervical cancer cells, and increases their sensitivity to CDDP via down-regulation of the expression of the target gene for ALDH1A1. Therefore, during cervical carcinoma treatment, increasing the level of miR-23b may produce a chemotherapeutic effect.</p> <p><strong>Keywords</strong>: MiR-23b, Acetaldehyde dehydrogenase 1A1, Cervical cancer, Cisplatin, Sensitivity </p> Yongbing Tao, Fuyun Mao, Weihong Gu, Ling Wu, Jing Guo, Ping Xu Copyright (c) https://www.ajol.info/index.php/tjpr/article/view/204748 Wed, 17 Mar 2021 00:00:00 +0000 Bone morphogenetic protein 2/7 promotes repair of bone defect via induction of endochondral ossification https://www.ajol.info/index.php/tjpr/article/view/204749 <p><strong>Purpose:</strong> To study the influence of bone morphogenetic protein 2/7 (BMP2/7) on repair of bone defect, and the mechanism involved.<br><strong>Methods:</strong> Bone marrow stromal cells (BMSCs) were randomly assigned to 2 groups: control and transfection groups. The cells were transfected with rBMP2/7 recombinant adenovirus. Cell growth and alkaline phosphatase (ALP) activity were determined in both groups. Rabbit model of femoral bone defect was prepared using standard methods. Male New Zealand white rabbits were randomly assigned to 3 groups, each of which had 10 rabbits: control, gelatin and BMP2/7 groups. Histopathological and xray examinations, and three-point bending flexural test were used to compare the potential of gelatin and BMP2/7 to repair bone defects.<br><strong>Results</strong>: Transfection of BMSCs with rBMP2/7 recombinant adenovirus significantly enhanced their growth (p &lt; 0.05). Alkaline phosphatase (ALP) level was also markedly and time-dependently higher in transfection group than in control group (p &lt; 0.05). Rabbits with grade 4 bone healing or above were more in BMP2/7-treated category than in control and gelatin groups. New bone hyperplasia with typical lamellar bone structure, irregular medullary cavity, as well as transition from osteoblast to osteocyte were observed in BMP2/7 group. Moreover, maximum flexural strength and repair were significantly higher in BMP2/7-transfected group than in control.<br><strong>Conclusion:</strong> These findings indicate that BMP2/7 promotes the repair of bone defect via induction of endochondral ossification in rabbits.

The expression levels of miR-200c in the two types of tissues were determined. Cells of human nasopharyngeal carcinoma cell line HNE1 were cultured to about 70 % growth prior to transfection with blank plasmid, PINI and miR-200c analogs. After 48 h of culture, control group, PINI group, and miR-200c over-expression + PINI group were obtained. The expression levels of PINI and changes in centrosomes in each group were measured, and changes in cell migration in each group were determined using Transwell migration assay.<br><strong>Results</strong>: Compared with para-cancerous normal tissues, the expression level of miR-200c in nasopharyngeal carcinoma was&nbsp; significantly increased (p &lt; 0.01). Compared with the control group, the PINI expression level and cell migration ability in miR-200c overexpression tissue were markedly decreased, while the percentage of extra centrosomes was markedly increased. Compared to miR-200c over-expression tissue, the PINI expression level and cell migration ability in the miR-200c overexpression + PINI group were markedly raised, while the percentage of extra-central somatic cells was significantly decreased (p &lt; 0.05).<br><strong>Conclusion</strong>: MiR-200c may inhibit the migration of nasopharyngeal carcinoma cells by inhibiting the expression of PINI and inhibiting abnormal expansion of centrosomes.</p> <p><strong>Keywords:</strong> MiR-200c, Nasopharyngeal carcinoma, Biological function, Molecular regulatory mechanism </p> Sheng Xu, Wenxia He Copyright (c) https://www.ajol.info/index.php/tjpr/article/view/204751 Wed, 17 Mar 2021 00:00:00 +0000 Expression levels of apoptotic factors in a rat model of corticosteroid-induced femoral head necrosis https://www.ajol.info/index.php/tjpr/article/view/204752 <p><strong>Purpose:</strong> To study the expression levels of apoptotic factors in corticosteroid-mediated femoral head necrosis (FHN) in rats.</p> <p><strong>Methods</strong>: Sprague-Dawley (SD) rats (n = 60) bred adaptively for one week were randomly assigned to control and model groups (30 rats/group). A rat model of corticosteroid-induced femoral head necrosis was established. Then, 3 mL of blood drawn from the inferior vena cava of each rat was used for the assay of the expression levels of osteoprotegerin (OPG) and osteoclast differentiation factor (RANKL) in each group using enzyme-linked immunosorbent assay (ELISA).

The purpose of this work was to explore the levels of serum Sestrin2 and PlGF in pregnant women with PE and their correlation with the severity index of the disease.<br><strong>Methods</strong>:This was a retrospective case-control study of pregnant women with PE who planned to give birth in our hospital from 05/2017 to 05/2019. Pearson correlation was used to analyze Sestrin2 and PlGF levels with PE severity. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of Sestrin2 and PlGF for PE.<br><strong>Results</strong>: There were 52 women in the control group, 46 in the mild PE group, and 36 in the severe PE group. As the severity of PE increased, the median levels of Sestrin2 increased (8.1, 9.8, and 11.8 ng/ml), and the levels of PlGF decreased (156, 117, and 67 pg/ml) in the three groups of women (all P&lt;0.05).The levels of Sestrin2 and PlGF were strongly correlated with mean arterial pressure,<br>proteinuria, newborn birth weight and gestational weeks at delivery (all P&lt;0.001). Sestrin2 and PlGF had high efficiency of diagnosing PE (cut-off: 8.90 ng/ml, Area Under Curve [AUC]=0.979; cut-off: 122.50 pg/ml, AUC=0.963). Additionally, Sestrin2 and PlGF showed high value of severity prediction (cut-off: 11.15 ng/ml, AUC=0.857; cut-off: 68.50 pg/ml, AUC=0.837).<br><strong>Conclusion</strong>: Sestrin2 and PlGF are correlated with the severity of PE.

Next BV-2 cells were stimulated using lipopolysaccharide (LPS, 200 ng/mL) and then administered 20 μM dexmedetomidine. Blood glucose levels, body weight, and paw withdrawal threshold (PWT) were measured once a week in DNP rats. Transfection was performed, and luciferase<br>reporter assay was used to verify microRNA (miR)-337 binding to Rap1A mRNA. Reverse transcriptionpolymerase chain reaction (RT-PCR) was used to measure the levels of miR-618 and P2Y12 while the protein levels of P2Y12 and ionized calcium-binding adaptor molecule 1 (IBA-1) were determined by western blot analysis.<br><strong>Results</strong>: Dexmedetomidine treatment significantly increased PWT (p &lt; 0.01) in DNP rats and decreased miR-618 expression (p &lt; 0.01) but increased P2Y12 expression (p &lt; 0.01) in the spinal cord of DNP rats. Luciferase reporter assay data showed that the presumed binding site of miR-618 is located in the 3′-untranslated regions of P2Y12. MiR-618 overexpression significantly reduced P2Y12<br>levels (p &lt; 0.01). Dexmedetomidine upregulated P2Y12 expression (p &lt; 0.01) but decreased IBA-1 expression (p &lt; 0.01).<br><strong>Conclusion</strong>: Dexmedetomidine application attenuates DNP by inhibiting microglial activation via the regulation of miR-618/P2Y12 pathway.

The two levels of sevoflurane were provided through a gas monitor connected to each of the sevoflurane groups. The control group was not treated. Flow cytometry was used to analyze A549 cell apoptosis, while qRT-PCR was used for assay of the levels of miRNA155 in A549 cells. The protein expression of Bcl-2 was determined with immunoblotting. The percentage of apoptosis and levels of miRNA155 and Bcl-2 in the two cell lines were compared.<br><strong>Results</strong>: Significant differences in miRNA146a level were seen between the 3 % sevoflurane and control groups at 3 h. There was higher apoptosis in the 3 % sevoflurane group, relative to control, but miRNA155 levels in the 3 % sevoflurane group were generally less than that of the control (p &lt; 0.05). There was lower Bcl-2 content in the 3 % sevoflurane group than in control group (p &lt; 0.05).<br><strong>Conclusion</strong>: Sevoflurane exerts strong apoptotic and anti-proliferative effects on lung adenocarcinoma A549 cells via a mechanism which may be related to the downregulation of miRNA155, thereby inhibiting the expression of anti-apoptotic protein Bcl-2.

Apoptotic cell death was assessed by AO/ETBR staining and western blotting techniques. The levels of reactive oxygen species (ROS) were measured using 2,7, dicholoro dihydrofluoresceindiacetate (H2DCFDA) staining.<br>Cell migration and invasion were monitored with Transwell chamber assay. Western blotting assay was used to determine the expression levels of proteins of the MEK/ERK signaling pathway.<br><strong>Results</strong>: Swertiamarin induced dose- and time-dependent inhibition of proliferation of HeLa cervical cancer cells (p &lt; 0.05). It also suppressed the colony formation potential of HeLa cells, and induced various structural modifications in HeLa cells. Swertiamarin exposure resulted in the formation of earlyapoptotic, late-apoptotic and necrotic cells, and significant modulation of apoptosis-allied proteins. It was observed that the migration and invasion of HeLa cells were potentially suppressed in dose-reliant fashion by swertiamarin. Western blotting results showed that the expressions of p-MEK and p-ERK were markedly reduced, while those of MEK and ERK were unaffected (p &lt; 0.05).<br><strong>Conclusion:</strong> Swertiamarin exerts in vitro anticancer activity against cervical cancer cells (HeLa).

Histopathological renal damage was examined using hematoxylin and eosin (H &amp; E) staining while creatinine and cytokines were measured using commercial kits. Protein levels were determined by Western blotting.<br><strong>Results</strong>: Vacuoles, dilations, degeneration, and necrosis were observed in CLP mouse kidneys, but these alterations were countered by 20 mg/kg of ligustilide. Serum creatinine, blood urea nitrogen (BUN), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 were significantly increased in CLP mice compared with control. Furthermore, the serum levels of these indicators in serum were lowered by ligustilide (p &lt; 0.01). The expression levels of Toll-like receptor 4 (TLR4) TLR4 and phosphorylated nuclear factor (NF)-κB in CLP mice were also downregulated by ligustilide.

Long noncoding RNA SNHG1 has presented its protective role in cardiomyocytes previously. Herein, we examined the underlying molecular mechanisms of SNHG1 in cardiac muscle cells from hypoxia and re-oxygenation (H/R) in vitro.<br><strong>Methods</strong>: RT-qPCR measured expression of SNHG1, miR-21-5p and miR-30a-5p in rat cardiac muscle cell line HL-1 before and after H/R treatment and cell transfection, which was applied to regulate expression of SNHG1, miR-21-5p and miR-30a-5p for further use. The flow cytometry method was used to compare changes in cellular apoptosis, and cell viability was measured by CCK-8 method.<br>Bioinformatics predicted the bindings ofSNHG1 and miR-21-5p / miR-30a-5p while the luciferase reporter assays further verified this.<br><strong>Results</strong>: The outcomes revealedthat SNHG1 was downregulated and meanwhile miR-21-5p / miR-30a5p was elevated that enhanced apoptosis and reduced cell viability in HL-1 cells. However, overexpressed SNHG1 inhibited cell apoptosis and increased cell viability brought by H/R. In addition, SNHG1 targeted at miR-21-5p/ miR-30a-5p, which contributed to the inter-regulation in between. Furthermore, interactive experiments revealed that upregulation of miR-21-5p/ miR-30a-5p added to the cell apoptosis which was induced by H/R and partially counteracted by the upregulation of SNHG1.<br><strong>Conclusion</strong>: In this study we have demonstrated the protective role of SNHG1 in the moderation of H/R-induced HL-1 apoptosis and viability through suppression of miR-21-5p/miR-30a-5p.

M. oleifera leaf extract at doses 100, 200 and 400 mg/kg were given to 3 groups of type 2 diabetic rats. The area under curve (AUC) of glucose and homeostasis model assessment of insulin resistance (HOMA-R) were calculated using appropriate formulas, whereas levels of glucose,<br>insulin, peroxisome proliferator activated receptor-γ (PPARγ, dipeptidyl peptidase-IV (DPP-IV) and inflammatory cytokines (IL-6, IL-1β and TNFα) were assayed using ELISA kits.<br><strong>Results</strong>: The leaf extract of <em>M. oleifera</em> significantly reduced the levels of glucose, insulin and cytokines in treated type 2 diabetic groups (p &lt; 0.05). DC group had significantly increased AUC for glucose, whereas the extract-treated groups showed significant&nbsp; decrease in glucose AUC. There was significant decrease in insulin sensitivity parameters, as indicated by increase in HOMA-R and decrease in PPARγ levels in the DC group (p &lt; 0.05). However, treatment with the <em>M. oleifera</em> extract reversed this trend via marked decrease in HOMA-R level and significant rise in PPARγ level. In contrast, the extract had no effect on DPP-IV concentration in diabetic treated groups (p &lt; 0.05).<br><strong>Conclusion</strong>: These results indicate that <em>M. oleifera</em> leaf extract mitigates hyperglycemia in type 2 DM by modulating hyperinsulinemia, PPARγ and inflammatory cytokines.

More than half of the participants had comorbid disease conditions (53.9 %), particularly hypertension (47.1 %). Nearly a quarter of the participants with CV disease conditions used non-selective NSAIDs (25.5 %). The majority of NSAIDs intake were orally administered for more than one month (79.4 %). Physicians were the major source for patient education about the risk of NSAIDs-associated complications according to 59.6 % of the participants. The majority of participants reported non-adherence to the prescribed PPIs (86.5 %). There was a statistically significant difference between the participants that used NSAIDs alone, and those with PPI co-prescription within the age group of 31 - 60 years (p &lt; 0.0001) and for a duration of more than one month for NSAIDs administration (p &lt; 0.0001).<br><strong>Conclusion</strong>: There is improper use of NSAIDs, particularly the non-selective agents, among patients with co-morbid cardiovascular disease conditions, as well as poor medication adherence and improper co-prescription of PPIs. This requires periodic revision for long-term intake of NSAIDs, while applying more care to high-risk patients regarding co-prescription of NSAIDs with PPIs.</p> <p><strong>Keywords</strong>: Cardiovascular, Co-morbidity, Gastrointestinal complications, NSAIDs, Proton-pump inhibitors</p> Anmar Al-Taie, Ali N.

During the surgical procedure, Sev was administered via a mask, while Pro was<br>given i.v. Each anesthesia was followed with fentanyl administration.<br>Results: Pain scores such as verbal rating scale (VRS) and visual analogue scale (VAS) were slightly<br>lower in Sev group than in Pro group. However, post-operative conditions such as emergence delirium<br>(ED) and emergence agitation (EA) were significantly elevated in Sev group, when compared to Pro<br>group (p &lt; 0.05). In addition, patients in Sev group had higher levels of hemodynamic parameters<br>(blood pressure), and much higher number of adverse events than those in Pro group. Thus, the overall<br>satisfaction score and recovery characteristics, i.e., hospitalization time and recovery were slightly<br>better in Pro-anesthetized children than in those given Sev.<br>Conclusion: These results suggest that except for pain score, Pro-anesthetized children fared better in<br>terms of speedy recovery and reduced adverse effects than those given Pro. Thus, Pro may be<br>recommended as general anaesthetic for children undergoing otolaryngology surgical procedures.<br>Keywords: Sevoflurane, Propofol, Pain score, Emergence agitation, Otolaryngology</p> Yanwu Wang, Fan Yao, Yulong Lin, Shugen Xiao Copyright (c) https://www.ajol.info/index.php/tjpr/article/view/204836 Fri, 19 Mar 2021 00:00:00 +0000
