Impact of Glyphosate on the Rhizosphere Microbial Communities of An EPSPS-Transgenic Soybean Line ZUTS31 by Metagenome Sequencing.

BACKGROUND: The worldwide use of glyphosate has dramatically increased, but also has been raising concern over its impact on mineral nutrition, plant pathogen, and soil microbiota. To date, the bulk of previous studies still have shown different results on the effect of glyphosate application on soil rhizosphere microbial communities. OBJECTIVE: This study aimed to clarify whether glyphosate has impact on nitrogen-fixation, pathogen or disease suppression, and rhizosphere microbial community of a soybean EPSPS-transgenic line ZUTS31 in one growth season. METHOD: Comparative analysis of the soil rhizosphere microbial communities was performed by 16S rRNA gene amplicons sequencing and shotgun metagenome sequencing analysis between the soybean line ZUTS31 foliar sprayed with diluted glyphosate solution and those sprayed with water only in seed-filling stage. RESULTS: There were no significant differences of alpha diversity but with small and insignificant difference of beta diversity of soybean rhizosphere bacteria after glyphosate treatment. The significantly enriched Gene Ontology (GO) terms were cellular, metabolic, and single-organism of biological process together with binding, catalytic activity of molecular function. The hits and gene abundances of some functional genes being involved in Plant Growth-Promoting Traits (PGPT), especially most of nitrogen fixation genes, significantly decreased in the rhizosphere after glyphosate treatment. CONCLUSION: Our present study indicated that the formulation of glyphosate-isopropylamine salt did not significantly affect the alpha and beta diversity of the rhizobacterial community of the soybean line ZUTS31, whereas it significantly influenced some functional genes involved in PGPT in the rhizosphere during the single growth season.

Effect of maternal oxygen supplementation for parturient undergoing elective cesarean section by high-flow nasal oxygen compared with room air on fetal acidemia: study protocol for a randomized controlled trial.

BACKGROUND: Maternal oxygen supplementation is usually used as an intrauterine resuscitation technique to prevent fetal hypoxia and acidemia during delivery. However, there has been a great deal of controversy regarding the effects of prophylactic maternal oxygen during cesarean section, during which the incidence of fetal acidemia seems to be higher compared with that during labor. High-flow nasal oxygen (HFNO) can improve oxygenation better in patients with high-flow oxygen airflow. The purpose of this study is to determine whether maternal oxygen supplementation with HFNO has a positive effect on fetal acidemia during cesarean section through umbilical arterial blood gas analysis. METHOD: This prospective, single-center, randomized, double-blinded trial will enroll 120 patients undergoing cesarean section. Participants will be randomly assigned to the HFNO group or air group at a 1:1 ratio. For parturients in the HFNO group, the flow rate is 40L/min, and the oxygen is heated to 37℃ with humidity 100% oxygen concentration through the Optiflow high-flow nasal oxygen system. And for the air group, the flow rate is 2 L/min with an air pattern through the same device. The primary outcome was umbilical artery (UA) lactate. Secondary outcomes include UA pH, PO2, PCO2, BE, the incidence of pH < 7.20 and pH < 7.10, Apgar scores at 1 and 5 min, and neonatal adverse outcomes. DISCUSSION: Our study is the first trial investigating whether maternal oxygen supplementation with HFNO can reduce the umbilical artery lactate levels and the incidence of fetal acidemia in cesarean section under combined spinal-epidural anesthesia. TRIAL REGISTRATION: ClinicalTrials.gov NCT05921955. Registered on 27 June 2023.

The synthesis and structure-activity relationship (SAR) studies of praziquantel derivatives with activity against adult Schistosoma japonicum are described. Several of them showed better worm killing activity than praziquantel and could serve as leads for further optimization.

[Effectiveness and safety of tranexamic acid in patients receiving on-pump coronary artery bypass grafting without clopidogrel and aspirin cessation].

OBJECTIVE: To evaluate the effectiveness and safty of tranexamic acid in patients receiving on-pump coronary artery bypass grafting (CABG) without clopidogrel and aspirin cessation. METHODS: The current study is a prospective, randomized and placebo-control trial. A total of 116 patients receiving selective on-pump CABG with their last ingestion of clopidogrle and aspirin within 7 days preoperatively were recruited. Despite 6 patients withdrawal their consent, the rest 110 were randomized to receive tranexamic acid or placebo. The tranexamic acid regimen was a bolus of 10 mg/kg followed by a maintenance of 10 mg·kg(-1)·h(-1) throughout the surgery. The primary outcome was the volume of allogeneic erythrocyte transfused perioperatively. RESULTS: Baseline characteristics were comparable between the groups. In patients receiving tranexamic acid and placebo respectively, the volume of allogeneic erythrocyte transfused was 4.0 (7.5) units and 6.0(6.0) units (W = 1021, P < 0.01). In these 2 groups respectively, blood loss was 930 (750) ml and 1210 (910) ml (W = 1042, P < 0.01), the incidence of major bleeding was 50.9% and 76.4% (χ(2) = 7.70, P < 0.01), the incidence of reoperation was 0 and 9.1% (χ(2) = 5.24, P = 0.02); the volume of plasma transfused was 400 (600) ml and 600 (650) ml (W = 1072, P = 0.01), the exposure of plasma was 60.0% and 85.5% (χ(2) = 8.98, P < 0.01) and the exposure to any allogeneic blood products was 85.5% and 98.2% (χ(2) = 5.93, P = 0.01). Perioperative mortality, morbidity and the incidence of adverse events were balanced between the groups without statistical significance. CONCLUSION: Tranexamic acid reduced significantly postoperative bleeding and transfusion in patients receiving on-pump CABG without clopidogrel and aspirin cessation.

Revelation of contributing mechanism of reactive oxygen species in photocatalytic ozonation heterocyclization of gaseous hexane isomers.

The reactive oxygen species (ROS) involved photocatalytic ozonation of gaseous n-hexane to heterocyclic compounds has been recently reported. However, whether such heterocyclization reaction happens on other alkanes and what is the contributing mechanism of ROS to the heterocyclic compound formation are still unclear. In present study, photocatalytic ozonation of three n-hexane's isomers (i.e. 2-methypentane, 3-methylpentane and 2,3-dimethylbutane) on Cu2O-CuO/TiO2-foam ceramic was investigated. Within reaction period, 2-methylpentane and 3-methylpentane not only showed higher average degradation efficiency than 2,3-dimethylbutane, but also separately converted to interfacial heterocyclic compounds of 5,5-dimethyldihydro-2(3H)-furanone and 4,5-dimethyl-4,5-dihydro-2(3H)-furanone. Enough reaction time, optimum experimental atmosphere and shorter light wavelength benefited the formation of heterocyclization products. None of O3, 1O2, electron and hole directly contributed to the heterocyclic compound formation. While •O2- dominated the production of the heterocyclic compound under the dry reaction atmosphere and •OH showed more important role than •O2- in the heterocyclic compound formation under the moist reaction atmosphere. Theoretical calculation confirmed that •OH or •O2- induced heterocyclization reaction of alkane was exothermic, while the former reaction released 0.47 eV higher energy than the later reaction. The findings provide a comprehensive understanding of contributing roles of ROS in heterocyclization reaction of alkanes, and are helpful for effective elimination of industrial alkanes by advanced oxidation methods.

Ultrasonography-assisted assessment of the influence of the volar prominence of the plate on the median nerve in distal radius fractures.

OBJECTIVE: The study aimed to explore the effect of differing volar locking plate (VLP) prominence on the median nerve (MN) in distal radius fracture (DRF) with ultrasound assistance to guide clinical treatment. METHODS: Forty-four patients who received VLP for DRF at our department were admitted and followed-up between January 2019 and May 2021. Different plate positions were graded using Soong classification; 13 were Grade 0, 18 were Grade 1, and 13 were Grade 2. The MN parameters at different wrist positions in patients with different Soong grades were measured with ultrasound assistance, including the median nerve cross-sectional area (MNCSA), diameter in the radial-ulnar direction (D1), and diameter in the dorsal-palmar direction (D2). The sensation in the affected finger and grip strength were collected at follow-up, scored using the Disabilities of the Arm, Shoulder, and Hand (DASH) scale to determine function, and statistically analysed. RESULTS: The MNCSA differed significantly across Soong grades. The MNCSA at the flexed, neutral, and extended wrist positions was smallest at Grade 0 and largest at Grade 2 (P < 0.05), and that at the neutral position was not significantly different between Grades 1 and 2 (P > 0.05). There was no significant interaction between the wrist positions and Soong grade (P > 0.05). The differences in D1 and D2 among different Soong grades were not statistically significant (P > 0.05). There were no statistical differences in grip strength, DASH, and sensation among different Soong grades (P > 0.05). CONCLUSIONS: Differing plate protrusions in DRF treatment did not cause clinical symptoms during follow-up; however, excessive plate protrusion (Soong Grade 2) increased the cross-sectional area of the MN. We recommend placing the plate as proximal as possible during VLP treatment of DRFs to avoid excessive bulges affecting the MN.

Epidemiological characteristics and spatiotemporal patterns of scrub typhus in Yunnan Province from 2006 to 2017.

Scrub typhus is an acute infectious disease in humans. A temporal, spatial and epidemiologic study was conducted to understand the characteristics of scrub typhus in Yunnan, to assist public health prevention and control measures. Based on the data on all cases reported in Yunnan during 2006-2017, we characterized the epidemiological features. Spatio-temporal patterns and Q-type cluster method were adopted to analyze the incidence of scrub typhus in Yunnan. In total, 27,838 scrub typhus cases were reported in Yunnan during 2006-2017. Of these, 49.53% (13,787) were male and 50.47% (14,051) were female (P > 0.05). Most patients were farmers (71.70%) (P < 0.05) and children aged 0-5 years (13.16%) (P < 0.01), which accounted for 84.86% of the total cases. An almost 20-fold increase in the number of patients was observed in 2017 (6,337 cases) compared to 2006 (307 cases). Baoshan and Lincang had the most cases accounting for 41.94%, while Diqing had the lowest incidence (only 3 cases). Sixteen municipalities infected were classified into three groups numbered in sequence. The incidence of scrub typhus in Yunnan is high and the annual incidence increased noticeably over time. Our results also indicate that surveillance and public education need to be focused on Baoshan, Lincang and Dehong.

The complete chloroplast genome of Rhododendron shanii W.P. Fang (Ericaceae), a endemic plant from the Southern Dabie Mountains of China.

Rhododendron shanii W.P. Fang 1983 (Ericaceae) is woody plant naturally distributed in the southwest of Anhui, China. The complete chloroplast genome sequence of R. shanii was generated by whole-genome next-generation sequencing data and assembled based on three Rhododendron species chloroplast genome. The complete chloroplast genome sequence of R. shanii was 204,170 bp and divided into four distinct regions: small single-copy region (2615 bp), large single-copy region (107,189 bp), and a pair of inverted repeat regions (47,183 bp). The genome annotation displayed 150 genes, including 95 protein-coding genes, 47 tRNA genes, and eight rRNA genes. Phylogenetic analysis with the Ericaceae reported chloroplast genomes revealed that R. shanii is sister to the clade comprising R. delavayi, R. griersonianum and R. platypodum.

Occlusion-Aware Self-Supervised Monocular 6D Object Pose Estimation.

6D object pose estimation is a fundamental yet challenging problem in computer vision. Convolutional Neural Networks (CNNs) have recently proven to be capable of predicting reliable 6D pose estimates even under monocular settings. Nonetheless, CNNs are identified as being extremely data-driven, and acquiring adequate annotations is oftentimes very time-consuming and labor intensive. To overcome this limitation, we propose a novel monocular 6D pose estimation approach by means of self-supervised learning, removing the need of real annotations. After training our proposed network fully supervised with synthetic RGB data, we leverage current trends in noisy student training and differentiable rendering to further self-supervise the model on these unsupervised real RGB(-D) samples, seeking for a visually and geometrically optimal alignment. Moreover, employing both visible and amodal mask information, our self-supervision can be very robust towards challenging scenarios such as occlusion. Extensive evaluations demonstrate that our proposed self-supervision is able to significantly enhance the model's original performance, outperforming all other methods relying on synthetic data or employing elaborate techniques from the domain adaptation realm. Noteworthy, our self-supervised approach achieves almost 50% relative improvement between methods purely trained with synthetic data and fully-supervised methods trained with real-world annotations.

Morphine pretreatment protects against cerebral ischemic injury via a cPKCγ-mediated anti-apoptosis pathway.

It has been reported that morphine pretreatment (MP) can exert neuroprotective effects, and that protein kinase C (PKC) participates in the initiation and development of ischemic/hypoxic preconditioning in the brain. However, it remains unknown whether PKC is involved in MP-induced neuroprotection. The aim of the present study, which included in vivo and in vitro experiments, was to determine whether the conventional γ isoform of PKC (cPKCγ) was involved in the protective effects of MP against cerebral ischemic injury. The present study included an in vivo experiment using a mouse model of middle cerebral artery occlusion and an in vitro experiment using neuroblastoma N2a cells with oxygen-glucose deprivation (OGD). Furthermore, a cPKCγ antagonist, Go6983, was used to determine the involvement of cPKCγ in the protective effects of MP against cerebral ischemic injury. In the in vivo experiment, neurological deficits, ischemic infarct volume, neural cell damage, apoptosis and caspase-3 activation were evaluated. In the in vitro experiment, flow cytometry was used to determine the activation of caspase-3 in N2a cells with OGD. It was found that MP protected against cerebral ischemic injury. However, intracerebroventricular injection of the cPKCγ antagonist before MP attenuated the neuroprotective effect of MP and increased the activation of cleaved caspase-3. These findings suggested that MP may provide protection against cerebral ischemic injury via a cPKCγ-mediated anti-apoptosis pathway.

Different Chinese herbal medicine therapy for idiopathic thrombocytopenic purpura: A protocol for systematic review and Bayesian network meta-analysis.

BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is a common immune system and blood system disease in clinical practice, and it is a hemorrhagic disease caused by immune factors causing platelet destruction and decreasing number of platelets. There is currently no effective treatment plan for ITP. At this stage, glucocorticoid and gamma globulin are mostly used in the treatment of ITP, and some patients use splenectomy to achieve therapeutic purposes, but the various treatment methods are inadequate. At this stage, a large number of randomized controlled studies have reported that Chinese herbal medicine has achieved good curative effect in the treatment of ITP. However, due to the variety of Chinese herbal medicine, there has been no evidence of the effectiveness and safety of Chinese herbal medicine in the treatment of ITP. Because of the above reasons, this study uses the network meta-analysis method based on Bayesian method to compare the clinical efficacy and safety of different kinds of Chinese herbal medicine in the treatment of ITP through direct and indirect comparison, in order to provide evidence-based medical support for the treatment of ITP with Chinese herbal medicine. METHODS: This study uses the method of combining free words with theme words, and using computer to retrieve PubMed, EMbase, The Cochrane Library, WANFANG Database, CNKI, and VIP Database, etc, to collect the randomized control studies on Chinese herbal medicine in the treatment of ITP. The retrieval time is from the establishment of each database to January 2021, and the retrieval languages are Chinese and English. Two researchers independently read the title, abstract and full text of the article to determine whether it is included in the literature; In the event of a disagreement, a third researcher will join the discussion to resolve the disagreement; For the literature that lacks information, trying to contact the original author of the document to supplement it. The literature quality evaluation carried out by using the Stata 14.0 software to draw network and funnel plots, in accordance with the quality evaluation criteria of version 5.1.0 of the Cochrane System Evaluation Manual. Statistical analysis is performed by using ADDIS 1.16.8 software based on the Bayesian model. RESULTS: This study will compare the clinical efficacy and safety of different types of Chinese herbal medicine in the treatment of idiopathic thrombocytopenic purpura through the method of network meta-analysis, and rank the different types of Chinese herbal medicine according to their effectiveness, and the results will be published in a peer-reviewed, high-quality academic journal. CONCLUSION: This study will find effective and safe Chinese herbal medicine for clinical treatment of ITP from the perspective of evidence-based medicine, and benefit more ITP patients.

An intraneural ganglion cyst of the ulnar nerve at the wrist: a case report and literature review.

BACKGROUND: Intraneural ganglion cysts of the ulnar nerve at the wrist are rare and poorly understood. We report a case of an intraneural ganglion cyst at the level of the wrist.Case presentation: A 48-year-old man presented with the complaints of weakness for 6 months and serious aggravation for 1 month in his right hand. After examinations, including ultrasound, the patient was diagnosed with an intraneural ganglion cyst. Intraoperatively, with exposure of the ulnar nerve, we found that the intraneural ganglion cyst was at the level of Guyon's canal and extended approximately 6 cm proximally. Postoperatively, sensation of the fingers was normal, but atrophy of his muscles and limited straightening of his ring and little fingers were similar to those preoperatively. CONCLUSIONS: Diagnosis of an intraneural cyst before surgery is mostly based on ultrasound and magnetic resonance imaging. Transection of the articular branch is an important measure to prevent recurrence of this cyst. If the ulnar nerve is compressed and causes symptoms, nerve decompression, including removal/aspiration of the cyst, and sometimes external neurolysis of the nerve, are necessary to relieve the symptoms and allow regeneration of the nerve. However, these should be performed without damaging the nerve fascicles.

Melone's concept revisited in comminuted distal radius fractures: the three-dimensional CT mapping.

BACKGROUND: There is no consensus in the literature about the ideal classification of the distal radius fracture for the clinical practice. The traditional Melone classification system divides the distal radius into four basic components, the shaft, radial styloid, dorsal medial fragment, and volar medial fragment. The aim of this study was to identify fracture lines in comminuted distal radius fractures using three-dimensional mapping of computed tomography (CT) images to test the hypothesis that fracture fragments can be divided according to the Melone classification. METHODS: Fifty-nine consecutive OTA/AO 23C3 fractures presented at the hospital between January 2018 and October 2019 were retrospectively reviewed. The fracture lines were characterized in the axial, sagittal, and coronal CT planes. After reducing the fractures in a three-dimensional (3D) model, the fracture lines were plotted from the CT images and were then superimposed on one another and oriented to fit a standard template. The area of articular surfaces was measured and compared to quantify the differences between the radial bone fragments. RESULTS: Thirty-five cases (59.3%) in this study fit the Melone classification and 24 cases (40.7%) did not. On the radiocarpal surface, there was a greater concentration of fracture lines in the dorsal area of the radius than in the volar area. On the distal radioulnar joint (DRUJ), the fracture lines were focused around two specific concentrated regions. For the articular surface area, the mean area of the radial styloid, volar medial fragment, and dorsal medial fragment was 141.13 ± 90.16 mm2, 147.79 ± 75.94 mm2, and 79.05 ± 70.73 mm2, respectively. There was a significant difference in articular surface area for the Melone fragments (P = 0.002). CONCLUSIONS: The Melone classification system is not suitable for characterizing all C3 fractures. The findings of this study confirm that the dorsal medial fragments are relatively comminuted and small. Extra care should be given to these small fragments when reducing the fracture.

Functional reconstruction of severe hand injuries using allogeneic tendons: a retrospective study.

OBJECTIVE: To evaluate the effectiveness and safety of allogeneic tendons for functional reconstruction of severe hand injuries. METHODS: From August 2007 to July 2014, we performed functional reconstruction with tendon allografts for severe hand injuries affecting two or more tendons. At the final follow-up, we assessed total active motion (TAM); pincer pinch strength; grip strength; Disabilities of the Arm, Shoulder, and Hand (DASH) score; degree of satisfaction; and adhesion. We measured the white blood cell count, C-reactive protein concentration, erythrocyte sedimentation rate, total T-cell count, and CD4+T/CD8+T ratio to evaluate the immune response and check for infection. RESULTS: Ten patients received 26 allogeneic tendons to reconstruct hand function. The average follow-up period was 50.0 months (range, 24-82 months). The TAM was 126.4° (12°-253°), pincer pinch strength was 0.83 kg (0-4.5 kg), and grip strength was 13.69 kg (4-41.5 kg). The DASH score was 14.25 (3.3-30.8), and seven and three patients were satisfied and partially satisfied, respectively. One patient developed tendon adhesion. All immune and infectious parameters were within the reference range. CONCLUSION: Functional reconstruction using allogeneic tendons for severe hand injuries with multiple tendon defects was effective and safe; however, more research is needed.

Effect of A2 pulley release on repaired tendon gliding resistance and rupture in a chicken model.

PURPOSE: Release of part of the A2 pulley has been suggested to improve function after zone II primary flexor tendon repairs. The purpose of this study was to measure the effect of A2 pulley release compared with pulley preservation on repaired tendon gliding resistance and rupture in the early postoperative period in a chicken model. METHODS: We divided 104 long toes from 52 Leghorn chickens into 2 experimental groups. In group 1, the flexor digitorum profundus tendons were cut completely and repaired surgically with either release or preservation of the A2 pulley. The tendon laceration was positioned so that the repair had to glide through the pulley with toe flexion. The toes were subjected to simulated active flexion at the end of the 2nd and 4th postsurgical weeks. The rupture rates of the tendons were recorded. In group 2, the volar two thirds of the tendons were cut and repaired, also in the region of the A2 pulley, with the pulley released or preserved. The force resisting tendon motion and the work of digital flexion with simulated active digital flexion were tested 3, 5, 7, and 14 days after surgery. RESULTS: At the end of the 2nd and 4th weeks, the tendon repairs showed significantly higher rates of rupture in the presence of an intact A2 pulley compared with those with the pulley released. Tendon gliding resistance was significantly increased with preservation of the pulley on postsurgical days 3, 5, 7, and 14; these toes required a greater number of motion cycles to reach steady levels of resistance and showed significantly higher steady resistance after digital motion. CONCLUSIONS: Release of the A2 pulley decreases the rate of repair rupture and the resistance to tendon gliding when the site of tendon repair has to glide through the pulley in the early postsurgical period. The findings of this study support partial release of the A2 pulley to favor successful tendon repair.

[Measurements of parameters of posteroanterior X-ray films of distal radial fracture and their significance].

OBJECTIVE: To provide the basic knowledge of wrist joint for diagnosing of these morphological change in pathological condition by measuring the posteroanterior X-ray films of different types of distal radius fracture by AO classification. METHODS: Eleven radiographic indexes were measured including following 7 new parameters of 83 cases of distal radius fracture: ulnar styloid length (USL), ulnar head length (UHL), ulnar head diameter (UHD), maximal distal radius width (MDRW), proximal distal radius width (PDRW), sigmoid notch length (SNL) and sigmoid notch width (SNW) by Pacs system in standard X-ray films. The indexes were defined by the ratio of these parameters to the length of the third metacarpal. Statistical significance of indexes and correlations of parameters were analyzed by SPSS 16.0. RESULTS: It was found that indexes of 11 parameters and 27 pairs of indexes had significantly different. Compared the indexes of 14 groups with normal group existed statistical significance, 62 pairs value of 11 parameters had correlations. CONCLUSION: The study provides additional radiographic index that will be helpful to more careful diagnosis and treatment of the distal radius fractures and their associated injuries such as ulnar wrist injuries or carpal instability.

Arsenic trioxide inhibits Skp2 expression to increase chemosensitivity to gemcitabine in pancreatic cancer cells.

The S-phase kinase associated protein 2 (Skp2), a member of the F-box protein family, regulates cell cycle progression and is highly expressed in pancreatic cancer (PC). Recently, we reported that arsenic trioxide (ATO) inhibited cell growth and invasion via downregulation of Skp2 in PC cells. Emerging evidence has revealed that Skp2 plays a crucial role in drug resistance in several kinds of cancers. Here, we determined whether ATO enhanced the sensitivity of PC cell lines to gemcitabine (GEM). We found that the combined treatment of ATO and GEM demonstrated strong antitumor effects in Patu8988 and Panc-1 PC cells. In addition, ATO potentiated the effects of GEM via downregulation of the Skp2 pathway in PC cells. Together, these findings suggested that Skp2 may be a promising therapeutic target to overcome resistance to GEM in PC.

Skp2 Expression Is Inhibited by Arsenic Trioxide through the Upregulation of miRNA-330-5p in Pancreatic Cancer Cells.

Arsenic trioxide (ATO) has been found to exert its anti-cancer activity in various human malignancies. In our previous report, we have shown that ATO inhibited cell growth and invasion via downregulation of Skp2 in pancreatic cancer (PC) cells. It has been extensively demonstrated that microRNAs (miRNAs) play a pivotal role in tumorigenesis. ATO might induce PC cell apoptosis and regulate Skp2 downregulation through the regulation of miRNAs. One study has demonstrated that miR-330-5p exerts a tumor-suppressive function in PC cell lines. Here, we investigated the role of miRNA-330-5p in ATO-mediated anti-tumor activity and explored whether ATO could regulate miR-330-5p in PC cells. We found that ATO treatment upregulated the expression of miR-330-5p. Moreover, miR-330-5p inhibitor rescued the ATO-mediated tumor-suppressive function. The combination of miR-330-5p mimic with ATO reduced cell growth, motility, and invasion, and enhanced apoptosis to a greater degree in PC cells. This study suggests that the combination of miR-330-5p mimic with ATO may be a potential therapeutic strategy for the treatment of PC.
