Abstract
OBJECTIVE The injuries of rotator cuff will cause the shoulder dysfunctions. Due to limited self-regeneration abilities of the tendon-bone part, rotator cuff injuries remain a clinical challenge. Previous studies have proposed many strategies for treating this disease. In this work, we aimed to combine different strategies to achieve better beneficial effects on tendon-bone repair. MATERIALS AND METHODS We isolated mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) and tested the effects of PRP on the gene expression, cell death resistance, and osteogenic differentiation of MSCs. Then, we utilized multiple strategies to treat rotator cuff injuries. We evaluated the expression of genes that related to tissue repair, bone formation, and tendon regeneration. We also tested the biomechanical property of repair tissues. RESULTS We found that the in-vitro co-culture with PRP endowed MSCs with enhanced production of growth factors, better osteogenic differentiation ability, and stronger ability to resist cell death. Next, we applied MSCs, PRP, and MSCs-PRP combined therapies in rat rotator cuff injury model to compare their therapeutic effects in vivo. Through biomechanical testing, we found that the combined therapy was most efficient to promote tissue regeneration and enhance the biomechanical property of the newly generated bone. CONCLUSIONS The combined treatment induced strongest signals related to angiogenesis, bone formation, and tendon generation in-situ. We demonstrated that the combination of MSCs and PRP synergistically promotes tendon-bone healing and holds great promise for the treatment of rotator cuff injuries.

Abstract
OBJECTIVES The clinical outcomes, safety, and efficacy of endovascular management are explored for symptomatic isolated superior mesenteric artery dissection (ISMAD). METHODS In this retrospective study, 51 consecutive patients with symptomatic ISMAD received endovascular management from three institutions between January 2011 and December 2019.These patients were categorized into group A (endovascular treatment was used as the first-line therapy) and group B(endovascular treatment was used as the second-line therapy). The general epidemiological data, clinical manifestations, first-episode symptoms, treatment process, imaging findings, follow-up outcomes were analyzed from the medical records. RESULTS A total of 51 patients with endovascular management were collected in this study. Significant differences were observed between the two groups with respect to the course (150 h vs. 57 h; p < 0.001), intestinal ischemia (26.32% vs. 6,25%; p = 0.04) and dissection length (45.26 ± 13.78 mm vs. 63.37 ± 12.73 mm; p < 0.001). Technical success rate was 90.2% (46/51). There was significant difference in the MOD (42.27 ± 23.41 min vs. 76.63 ± 28.62 min p < 0.001), MPSRT (4.67 ± 2.65 h vs. 7.32 ± 2.49 h, p = 0.02), LOS (9.52 ± 3.72 days vs. 11.86 ± 4.13 days; p = 0.01) between the two groups. The bleeding complication rate was 7.84% (one patient in group A and three patients in group B). A total of 48 (94.12%, 48/51) patients were followed up for a median of 36.51 months (range, 4-87 months). Positive events of the SMA were achieved in 81.25% (39/48), and negative events of the SMA were achieved in 18.75% (8/48) based on the follow-up contrast-enhanced CT scan. CONCLUSIONS Endovascular management of symptomatic ISMAD has a high technical success rate and efficient at controlling symptoms. Furthermore, as more positive events occur, endovascular management should be encouraged early when pain persists after conservative management or there are signs of disease progression.

Abstract
OBJECTIVES The aim of this study was to evaluate the computed tomography follow-up outcomes and radiographic findings of symptomatic isolated mesenteric artery dissection (IMAD) after conservative management. METHODS In this retrospective study, 130 consecutive patients with symptomatic IMAD from three institutions were enrolled from January 2011 to December 2019. The general epidemiological data, clinical manifestations, first-episode symptoms, imaging findings, and treatment strategy selection were analyzed from the medical records. RESULTS Among 130 patients diagnosed with symptomatic IMAD, positive remodeling of the SMA was achieved in 75.38% (98/130), and negative remodeling of the SMA was achieved in 24.62% (32/130). In the positive remodeling group, complete remodeling was achieved 39.23% (51/130) (type I 6 patients, type IIa 10 patients, type IIb 35 patients), in which type IIb was the most (p = 0.004). Moreover, of the 32 patients in whom negative remodeling of the SMA was achieved, significant differences were observed between the type IIa with respect to dissecting aneurysm formation (p = 0.04).Of the seven factors analyzed with a logistic regression model identified three factors significantly associated with negative remodeling: length of dissection (Waldχ2 13.331; OR 6.945; 95% CI 2.762-10.498; p = 0.014), true lumen residual diameter (TLRD) (Waldχ2 9.626; OR 7.85; 95% CI 1.892-19.063; p = 0.022), and branch involvement (Waldχ2 11.812; OR 7.247; 95% CI 1.245-14.830; p = 0.011). CONCLUSION The prognosis of most symptomatic IMAD has a tendency to positive remodeling after conservative management, in which the initial type IIb classification is common. In contrast, risk factors for negative remodeling were type IIa, length of dissection, TLRD, and branch involvement. Patients with these morphological characteristics may not benefit from conservative management.

Abstract
Intravascular leiomyomatosis (IVL) is a variant of leiomyoma characterized by intravascular proliferation of a histologically benign smooth muscle tumor extending beyond the uterus into distant great vessels or the heart. It is a rare disease and results in death. Here, we reported the case of 48-year-old, otherwise well woman, who presented to the emergency department with syncope. Pulmonary computed tomography (CT) demonstrated a large low-density shadow originating from the inferior vena cava (IVC) extending into the right atrium (RA). Magnetic resonance venography (MRV) showed that a neoplasm was "snakelike," which completely occluded the right internal iliac vein (RIIV), the common iliac vein (CIV), and IVC. A multidisciplinary team of specialists consisting of vascular surgeons, cardiac surgeons, gynecologists, anesthesiologists, and radiologists reviewed the history, clinical examination findings, and diagnostic imaging of the patient. A decision was made to proceed with one-stage surgery (resection of thoracoabdominal tumor extension at one operative setting). After surgery, the patient's vital signs were restored, and her symptoms were disappeared. She was discharged on hospital day 21 without complications. One-stage surgical approach to completely remove an IVL with RA involvement is an optimal choice if the patient's physical condition permits.

Abstract
OBJECTIVE Anterior cruciate ligament (ACL) injuries which cause knee disabilities remain a clinical challenge due to the compromised tendon-bone repair. Multiple strategies have been proposed to treat the tendon-bone injuries, and the combination of these therapies hold great potential to achieve synergistic effects. MATERIALS AND METHODS We built PLGA-BMP-2 (bone morphogenetic protein 2) system and confirmed the sustained release of BMP-2 both in vitro and in vivo. We then applied different therapies to treat rat ACL reconstruction. We collected the tissue sample and analyzed the BMP-2 concentration both in serum and in injured sites. We tested the mRNA expression of genes that were related to inflammation, tissue repair and bone formation in damaged tissues. We also analyzed the protein levels of some genes associated with tendon formation and check the function of newly generated bone through biomechanical test. RESULTS We found that, compared to monotherapies, simultaneous utilization of sustained BMP-2 release and platelet-rich fibrin (PRF) after anterior cruciate ligament reconstruction showed better therapeutic effects on tendon-bone healing in rat. This combined therapy efficiently enhanced the levels of growth factors that favor the angiogenesis and relieved the inflammatory responses in the injured sites. Of note, the combined therapy efficiently promoted the signals associated with bone formation and tendon regeneration. CONCLUSIONS We demonstrated that the combined therapy with BMP-2 and PRF achieves synergistic effects on tendon-bone healing and holds great potential for the treatment of ACL reconstruction.

Abstract
NL003 is a plasmid engineered to simultaneously express two isoforms of hepatocyte growth factor. This phase II study was performed to assess the clinical safety and efficacy of intramuscular injection of NL003 in critical limb ischemia (CLI) patients for 6 months. Two hundred patients (Rutherford scale 4-5) were randomly assigned: placebo (n = 50), low-dose NL003 (n = 50), middle-dose NL003 (n = 50), or high-dose NL003 (n = 50). The drug was administered in the affected limb of 197 patients on days 0, 14, and 28. No significant differences in the incidence of adverse events (AEs) or serious AEs were found among the groups. At 6 months, pain severity was significantly reduced in all NL003 groups, but not in the placebo group (p < 0.05). The proportion of patients with complete ulcer healing in the high-dose group was significantly higher than that of the placebo group (p = 0.0095). There were no statistically significant differences in transcutaneous oxygen pressure (TcPO2), ankle-brachial index (ABI), or toe-brachial index (TBI) value among the four groups throughout the study period. These results provide the first effective evidence of significant improvements in total healing of ulcers in treated legs, complete pain relief without analgesics, and safety for NL003 in patients with Rutherford stage 4-5.

Abstract
Abstract Objective To investigate the characteristics and patterns of factors such as victims' information, injury tools and time of occurrence of intentional injury cases in southwest China. Methods One thousand three hundred and forty intentional injury cases from several places in southwest China from 2014 to 2016 assessed as minor injury level Ⅱ and above had been randomly selected. Data on victims' information, motives, injury tools, sites of occurrence, time of occurrence, injured parts and degrees of injury were classified and gathered, and then association analyses of motives and types of injury tools as well as degrees of injury and injury tools were made. Results Most of the victims were young adults between 20-50 years (65.2%), male (82.3%), rural household registration (62.8%); the motives were mainly dispute (45.8%). Injury tools were mostly blunt (54.6%) or sharp (36.0%). Specifically, injuries were mostly made bare-handed (36.9%) and by cutting tools (33.2%); the cases mainly occurred in public areas (59.0%). Cases occurred more frequently in January (11.3%), February (13.1%), March (11.6%) and from 22:00 to 01:00 every night. Injuries mainly involved the craniofacial region. The wounds were mainly assessed as minor injury level Ⅱ (61.6%). There was statistical significance in the difference of types of injury tools among cases with different motives (P<0.05). There was statistical significance in the difference of the distribution of injury tools among cases with different degrees of injury (P<0.05). Conclusion The occurrence of intentional injury cases in southwest China has potential patterns and relevant influencing factors. Prevention and analysis of such cases need to be comprehensively considered from the aspects such as victims' information, injury tools and time of occurrence.

Abstract
Daclatasvir plus asunaprevir (DCV+ASV) treatment is an all-oral direct-acting antiviral (DAA) therapy for the genotype 1b HCV-infected patients. In this study, we investigated how resistance-associated substitutions (RASs) evolved after treatment failures and assessed the effect of those substitutions on viral fitness. Sequencing of NS5A and NS3 revealed typical RASs after treatment failures. Interestingly, the RASs of NS3 reverted to the wild-type amino acid within 1 year after treatment failures. However, the RASs of NS5A were stable and did not change. The effect of NS5A and NS3 RASs on viral RNA replication was assessed after mutagenic substitution in the genotype 1b HCV RNA. Among single substitutions, the effect of D168V was more substantial than the others and the effect of the triple mutant combination (D168V+L31V+Y93H) was the most severe. The RAS at NS5A Y93 affected both viral RNA replication and virus production. Finally, the effect of trans-complementation of NS5A was demonstrated in our co-transfection experiments and these results suggest that such a trans-complementation effect of NS5A may help maintain the NS5A RASs for a long time even after cessation of the DAA treatment. In conclusion, the results from this investigation would help understand the emergence and persistence of RASs.

Abstract
Recently, Juno, the oocyte receptor for Izumo1, a male immunoglobulin, was discovered. Juno is an essential glycosylphosphatidylinositol (GIP)-anchored protein. This result did not exclude the participation of other GIP-anchored proteins in this process. After bibliographic and database searches we selected five GIP-anchored proteins (Cpm, Ephrin-A4, Gas1, Gfra1 and Rgmb) as potential oocyte candidates participating in fertilisation. Western blot and immunofluorescence analyses showed that only three were present on the mouse ovulated oocyte membrane and, of these, only two were clearly involved in the fertilisation process, namely growth arrest specific 1 (Gas1) and glial cell line-derived neurotrophic factor receptor α1 (Gfrα1). This was demonstrated by evaluating oocyte fertilisability after treatment of oocytes with antibodies against the selected proteins, with their respective short interference RNA or both. Gfrα1 and Gas1 seem to be neither redundant nor synergistic. In conclusion, oocyte Gas1 and Gfrα1 are both clearly involved in fertilisation.

Abstract
Mice lacking genes involving in the DNA damage response (DDR) are often tumor prone owing to genome instability caused by oncogenic challenges. Previous studies demonstrate that activating transcription factor 3 (ATF3), a common stress sensor, can activate the tumor suppressor p53 and regulate expression of p53 target genes upon DNA damage. However, whether ATF3 contributes to the maintenance of genome stability and tumor suppression remains unknown. Here we report that Atf3-deficient (Atf3-/-) mice developed spontaneous tumors, and died significantly earlier than wild-type (Atf3+/+) mice. Consistent with these results, Atf3-/- mouse embryonic fibroblasts (MEFs) had more aberrant chromosomes and micronuclei, and were genetically unstable. Whereas we demonstrated that ATF3 activated p53 and promoted its pro-apoptotic activity in mouse thymi and small intestines, the chromosomal instability caused by Atf3 deficiency was largely dependent on the regulation of p53 by ATF3. Interestingly, loss of Atf3 also promoted spontaneous tumorigenesis in Trp53+/- mice, but did not affect tumor formation in Trp53-/- mice. Our results thus provide the first genetic evidence linking ATF3 to the suppression of the early development of cancer, and underscore the importance of ATF3 in the maintenance of genome integrity.

Abstract
Published data on the association between Toll-like receptor 4 (TLR4) Asp299Gly polymorphism and coronary heart disease (CHD) susceptibility are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. English-language studies were identified by searching PubMed and Embase databases (up to November 2016). All epidemiological studies were regarding Caucasians because no TLR4 Asp/Gly and Gly/Gly genotypes have been detected in Asians. A total of 20 case-control studies involving 14,416 cases and 10,764 controls were included in the meta-analysis. Overall, no significant associations were found between TLR4 Asp299Gly polymorphism and CHD susceptibility in the dominant model (OR=0.89; 95%CI=0.74 to 1.06; P=0.20) pooled in the meta-analysis. In the subgroup analysis by CHD, non-significant associations were found in cases compared to controls. When stratified by control source, no significantly decreased risk was found in the additive model or dominant model. The present meta-analysis suggests that the TLR4 Asp299Gly polymorphism was not associated with decreased CHD risk in Caucasians.
