RESUMO

Toll-like receptors (TLRs) can recognize specific signatures of invading microbial pathogens and activate a cascade of downstream signals to induce the secretion of inflammatory cytokines, chemokines, and type I interferons. The activation of TLRs triggers two downstream signaling pathways: the MyD88- and the TRIF-dependent pathways. To evaluate the therapeutic potential of epoxomicin, a member of the linear peptide α',ß'-epoxyketone first isolated from an actinomycetes strain, we examined its effects on signal transduction via TLR signaling pathways. Epoxomicin inhibited the activation of NF-kB and IRF3 induced by TLR agonists, decreased the expression of interferon-inducible protein-10, and inhibited the activation of NF-kB and IRF3 induced by overexpression of downstream signaling components of TLR signaling pathways. These results suggest that epoxomicin can regulate both the MyD88- and TRIF-dependent signaling pathways of TLRs. Thus, it might have potential as a new therapeutic drug for a variety of inflammatory diseases.

RESUMO

MUC4 is a predominant membrane-tethered mucin lubricating and protecting the epithelial surface and playing various biological roles in the renewal and differentiation of epithelial cells, cell signaling, cell adhesion, and carcinogenesis. Interestingly, recent studies have demonstrated that MUC4 expression regulates the epithelial-mesenchymal transition (EMT) of cancer cells in ovarian, pancreatic, and lung cancer. However, the effects of MUC4 expression on EMT in human airway epithelial cells are not yet well known. Here, we describe the effects of transforming growth factor beta 1 (TGF-ß1)-induced MUC4 expression on EMT and evaluate its downstream signaling pathway in human airway epithelial cells. In human airway epithelial NCI-H292 cells, exposure to TGF-ß1 induced expression of MUC4, CDH2, VIM and SNAI1 genes and encoded by them proteins, MUC4, N-cadherin, vimentin and Snail, and reduced the level of CDH1 and its product, E-cadherin. In MUC4-knockdown cells, TGF-ß1-induced expression levels of MUC4, CDH2, VIM and SNAI1 and corresponding proteins were suppressed, but CDH1 and E-cadherin levels were not. In addition, TGF-ß1-induced phosphorylation of extracellular signal regulated kinase 1/2 (ERK1/2) was suppressed, but that of Smad2/3, Akt, and p38 was not. The results of this study suggest that MUC4 silencing inhibits TGF-ß1 -induced EMT via the ERK1/2 pathway, and a possible role of MUC4 in the induction of EMT in human airway epithelial cells.

RESUMO

BACKGROUND: Airway inflammation and excessive mucin production are pathophysiological characteristics of airway diseases. Fipronil, a pesticide, is being extensively used in agriculture and veterinary medicine worldwide. However, this compound impairs immune function in non-target organisms. The present study aimed to evaluate the effect of fipronil on pro-inflammatory cytokine and mucus production and signalling pathways in human primary nasal METHODOLOGY: The effect of fipronil on pro-inflammatory cytokine and MUC5AC expression and the signalling pathway of fipronil were investigated using real-time PCR, enzyme immunoassays, immunofluorescence, and immunoblot analysis with specific inhibitors and small interfering RNA. RESULTS: Fipronil treatment increased pro-inflammatory cytokine interleukin (IL)-1beta, IL-6, IL-8, and MUC5AC expression in human primary nasal epithelial cells. It also induced phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2) mitogenactivated protein kinase (MAPK), p38 MAPK, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB). MAPK and NF-kB inhibitor treatment significantly inhibited increases in IL-1beta, IL-6, IL-8, and MUC5AC expression. Ex vivo data confirmed that fipronil-induced MUC5AC expression occurs through ERK1/2, p38, and NF-kB signalling pathways in nasal inferior turbinate tissue. CONCLUSIONS: Fipronil induced pro-inflammatory cytokine IL-1beta, IL-6, IL-8, and MUC5AC expression via ERK1/2 MAPK, p38 MAPK, and NF-kB in human primary nasal epithelial cells.

RESUMO

BACKGROUND: Intense noxious input from the periphery may result in central sensitization and hyperexcitability, thus accentuating subsequent postoperative pain. Parturients who undergo emergency cesarean section (C-sec) after experiencing labor pain often develop labor pain-induced sensitization. OBJECTIVE: This retrospective study evaluated whether parturients without epidural labor analgesia (ELA) who underwent emergency C­sec, experienced more severe postoperative pain and required more rescue analgesics during the postoperative period. METHODS: The institution's medical database was searched for parturients who underwent emergency C­sec under spinal anesthesia for any reason between January 2013 and December 2016. Those who underwent elective C­sec under spinal anesthesia were included as the reference arm. Parturients were divided into three groups: ELA, no-ELA and elective. Characteristics of patients and perioperative outcomes were evaluated. As primary outcomes, numerical rating scale (NRS) for postoperative pain (0-10) was recorded up to 96 h postoperatively, and use of rescue analgesics was evaluated at 6, 24, and 48 h postoperatively. RESULTS: In the ELA, no-ELA, and elective groups, 61, 73, and 88 parturients, respectively, were ultimately enrolled. The NRS for pain were similar among the three groups, except at 6 h postoperatively. Parturients in the no-ELA group demonstrated significantly higher NRS at 6 h postoperatively than those in the ELA group (P = 0.01).More patients in the no-ELA group required rescue analgesics than in the ELA (P = 0.001) and elective groups (P < 0.001) at 6-24 h postoperatively. Moreover, the proportion of patients requiring rescue analgesics ≥2 times was also significantly higher in the no-ELA group (vs. the ELA group, P = 0.004; vs. the elective group, P < 0.001). CONCLUSION: Parturients undergoing emergency C­sec without ELA management during labor experienced greater postoperative pain and a greater use of rescue analgesics during the postoperative period. The findings suggest that administration of ELA before emergency C­sec may act as pre-emptive analgesia against postoperative pain.

RESUMO

There have been few objective evaluations of the effects of deep neuromuscular blockade on intra-operative conditions. In this prospective randomised controlled study, we evaluated the effects of deep neuromuscular block on surgical conditions during laparoscopic colorectal surgery. Patients were randomly allocated using a computer-generated randomisation code to either moderate (train-of-four count 1-2 maintained and antagonised with neostigmine) or deep (post-tetanic count 1-2 maintained and reversed with sugammadex) levels of neuromuscular blockade. The primary outcome measure was the number of abrupt increases in intra-abdominal pressure intra-operatively. Secondary outcome variables were intra-operative restoration of spontaneous breathing, number of surgical requests for additional neuromuscular blockade, surgical rating of operating conditions and patient satisfaction. The surgeon who rated the surgical conditions score and investigator who checked the postoperative variables were blinded to patient allocation. In total, we recruited 70 patients of whom 64 (32 in each group) were analysed. Increases in intra-abdominal pressure (14/32 vs. 6/32; p = 0.031), intra-operative restoration of spontaneous breathing (16/32 vs. 2/32; p < 0.001) and request for additional neuromuscular blockade (21/32 vs. 8/32; p = 0.001) were more frequent in the moderate compared with the deep group. In patients undergoing elective laparoscopic colorectal surgery, deep neuromuscular blockade provided better surgical conditions than moderate neuromuscular blockade, as measured by a reduction in the incidence of intra-abdominal pressure alarms.

RESUMO

OBJECTIVE: To provide autonomy support from three dimensions based on self-determination theory (SDT), i.e. professional support, peer support, family support, and to investigate whether this intervention can improve diabetes self-management behavior and glycemic control of diabetic patients, and to analyze the influencing factors of the effect. METHODS: Using convenient sampling method, three communities were selected respectively in Beijing. Each community selected health service stations with similar conditions as different intervention groups. The diabetic patients managed by the station who were eligible for inclusion were recruited into this intervention group. The community stations were divided into three groups. The routine intervention group only issued knowledge manuals and conducted health management according to the requirements of basic public health services. Peer support groups were divided into small groups and carried out doctor-led group activities. Based on doctor-led peer support activities, the doctors and peers were trained to provide autonomy support based on self-determination theory, and their family members were trained in the form of manuals to provide autonomy support, forming a concerted support of the three dimensions. Activity processes and materials were also designed based on SDT. The intervention duration was 3 months, and the main evaluation indexes were HbA1c and patients' self-management behaviors, skills, knowledge, and self-efficacy scores. RESULTS: Before and after the intervention, the HbA1c of routine intervention group were 7.40%±1.37%, 7.30%±1.18%. The HbA1c of peer support group before and after the intervention were 7.33%±1.15% and 7.13%±1.27%. The HbA1c of autonomy support group before and after the intervention were 7.42%±1.22% and 6.78%±0.80%. Before and after the intervention, the self-management score in routine intervention group was 10.54±2.28 and 10.80±2.15, the score in peer support group was 11.09±1.89 and 11.40±1.78, the score in autonomy support group was 10.34±1.99 and 11.10±1.65, respectively. The HbA1c and self-management score increased higher in autonomy support group than in the other two groups. After intervention, the control rate in autonomy support group was higher than in the other two groups. According to the multi-factor analysis, the value of HbA1c after intervention was positively related to the baseline HbA1c, and negatively related to self-management behavior. The value in autonomy support group was higher than in routine intervention group. Baseline self-management behavior, self-efficacy, knowledge, skill, family support, autonomy support, peer support and age were positively correlated with the change of behavior. CONCLUSION: self-management behavior intervention based on self-determination theory can effectively promote self-management behavior and glycemic control of diabetic patients, and the effect is better than single peer support activities.

RESUMO

BACKGROUND: We evaluated the effect of magnesium sulphate on increased pain in 44 patients undergoing staged bilateral total knee arthroplasty (TKA). METHODS: The magnesium group (n=22) and the control group (n=22) received magnesium sulphate and isotonic saline, respectively, throughout the surgery. Postoperative pain (visual analogue scale, VAS) at rest and the amounts of patient-controlled analgesia (PCA, fentanyl) and rescue analgesia (ketoprofen) administered during the first 48 h were compared between the two groups and within each group between the first and second TKA. RESULTS: The VAS scores were significantly higher in the control group than in the magnesium group not only after the first TKA [29 (11) vs 19 (9) at 24 h and 33 (8) vs 24 (10) at 48 h; P=0.001] but also after the second TKA [44 (17) vs 20 (10) at 24 h and 43 (14) vs 25 (10) at 48 h; P<0.001]. In the control group, VAS scores were significantly higher for the second than for the first operated knee [44 (17) vs 29 (11) at 24 h and 43 (14) vs 33 (8) at 48 h; P<0.001 and P=0.006, respectively]. In the magnesium group, there were no significant differences in VAS scores between the first and second TKA. Magnesium significantly reduced the amounts of rescue analgesics and fentanyl administered over the first 48 h postoperatively. CONCLUSIONS: Magnesium sulphate administration significantly reduced postoperative pain and minimized the difference in pain intensity between the first and second operations.

RESUMO

We evaluated changes in rotational thromboelastometry (ROTEM(®) ) parameters and clinical outcomes in patients undergoing total hip replacement arthroplasty, with concomitant infusions of tranexamic acid and of 6% hydroxyethyl starch 130/0.4. Fifty-five patients were randomly assigned to either the tranexamic acid (n = 29) or the control (n = 26) group. Hydroxyethyl starch was administered in the range of 10-15 ml.kg(-1) during the operation in both groups. In the control group, the clot formation time and maximum clot firmness of APTEM showed significant differences when compared with those of EXTEM at one hour postoperatively, suggestive of fibrinolysis. In the tranexamic acid group, there was no significant difference between each postoperative EXTEM and APTEM parameter. In the tranexamic acid and control group, postoperative blood loss was 308 ml (210-420 [106-745]) and 488 ml (375-620 [170-910], p = 0.002), respectively, and total blood loss was 1168 ml (922-1470 [663-2107]) and 1563 ml (1276-1708 [887-1494], p = 0.003). Haemoglobin concentration was higher in the tranexamic acid group on the second postoperative day (10.5 (9.4-12.1 [7.9-14.0]) vs. 9.6 (8.9-10.5[7.3-16.0]) g.dl(-1) , p = 0.027). In patients undergoing total hip replacement arthroplasty, postoperative fibrinolysis aggravated by hydroxyethyl starch was attenuated by co-administration of 10 mg.kg(-1) tranexamic acid, which may have led to less postoperative blood loss.

RESUMO

UNLABELLED: Obstract: To characterize and analyze risky sexual networks and genetic scales to potential HIV transmission for HIV seroconcordant couples in Taizhou municipality of Zhejiang Province. METHODS: HIV seroconcordant positive couples were invited as index cases to participate in an egocentric survey on HIV related risky behavior and behavioral network prior to HIV diagnosis during 2008-2011. Within-couple HIV transmission pairs were determined by the combination of both behavioral and phylogenetic analysis. RESULTS: Totally 27 HIV seroconcordant couples were enrolled in this study. Male spouses were more likely to report having two or more sexual partners in the past years prior to HIV diagnosis than female spouses (88.9% vs. 37.0%). Among 27 couples, 20 couples including 17 couples by male but not female spouses, 3 couples by female but not male spouses reported having two or more sexual partners (i.e., multiple sexual partners) prior to HIV diagnosis; and 7 couples by both spouses reported having multiple sexual partners. Twenty four of 27 sexual networks were determined to be HIV transmission pairs (20) or potential transmission pairs (4), 3 couples were subtyped with discordant HIV subtypes or large genetic distance and thus had different sources of HIV transmissions. In addition, among 27 concordant couples, HIV drug resistance (HIVDR) or primary HIVDR existed in 6 ART-naïve participants in 4 networks; among them, 2 networks were determined to be potential HIVDR transmission couple pairs. CONCLUSIONS: The HIV strains isolated in HIV infected spouses characterized with diversity and CRF01_AE was the main strain subtype. One of the spouses with risky behavior infected HIV was the main route of transmission to other spouses through unprotected sexual contacts. HIVDR was isolated from some HIV infected individuals, suggesting the risk for HIVDR transmission in married couples. The results provide enhanced evidence for urgent development of tailored prevention strategies, such as couple-based HIV counseling and testing services to reduce HIV secondary transmission.

RESUMO

Total hip arthroplasty results in substantial blood loss in the peri-operative period. We evaluated the effects of acute normovolaemic haemodilution on blood coagulation and platelet function in 11 patients undergoing total hip arthroplasty. We performed acute normovolaemic haemodilution and haematological tests, rotational thromboelastometry (ROTEM(®) ) and whole-blood impedance aggregometry. Blood samples were obtained at three time points: (i) before the initiation of acute normovolaemic haemodilution; (ii) 20 min after completion of acute normovolaemic haemodilution; and (iii) 20 min after retransfusion. After acute normovolaemic haemodilution, ROTEM parameters demonstrated hypocoagulability. Clot formation time of INTEM was increased by 31.6% (p = 0.016), whereas the α-angle and maximum clot formation of INTEM decreased by 8.1% (p = 0.032) and 3.0% (p = 0.013) respectively, compared with baseline values. Clotting time and clot formation time of EXTEM were increased by 40.8% (p = 0.042) and 31.3% (p = 0.016), respectively, whereas the α-angle and maximum clot formation of EXTEM were decreased by 11.9% (p = 0.020) and 9.5% (p = 0.013), respectively. The maximum clot formation of FIBTEM decreased by 35.1% compared with the baseline value (p = 0.007). Following retransfusion, ROTEM values returned to baseline; clot formation time decreased and the α-angle and maximum clot formation increased. There were no significant changes in platelet aggregation during the study. At 20 min after the end of acute normovolaemic haemodilution, the international normalised ratio of prothrombin time was increased compared with the baseline value (p = 0.003). We conclude that acute normovolaemic haemodilution resulted in a hypocoagulable state compared with baseline values and that coagulation parameters returned to normal after retransfusion.

RESUMO

Human adenovirus 36 (Ad36) is positively associated with obesity in humans and animals. Ad36 infection is characterized by increased adiposity and inflammation. To investigate the possibility that a prophylactic vaccine candidate might protect against Ad36-induced obesity and inflammation, we purified Ad36 and ultraviolet-irradiated virus to obtain a vaccine candidate. After immunizing the mice with the vaccine candidate (vaccinated group), live Ad36 was injected into mice as a challenge test. Unvaccinated mice (control group) were immunized with phosphate-buffered saline and then challenged with live Ad36. Fourteen weeks after challenge, we compared adiposity and inflammation in vaccinated and control mice. The control group showed 17% greater body weight and 20% more epididymal fats compared with the vaccinated group. In addition, the vaccinated group had decreased serum levels of pro-inflammatory cytokines, and infiltrated immune cells, especially M1 macrophages, in fat tissue. Therefore, the vaccine candidate for Ad36 was able to protect against Ad36-increased body weight and fat as well as inflammatory states after challenge. These results provide proof-of-concept for prophylactic vaccination against virus-induced adiposity.

RESUMO

Human adenovirus Ad36 increases adiposity in several animal models, including rodents and non-human primates. Importantly, Ad36 is associated with human obesity, which has prompted research to understand its epidemiology and to develop a vaccine to prevent a subgroup of obesity. For this purpose, understanding the genomic stability of Ad36 in vivo and in vitro infections is critical. Here, we examined whether in vitro cell passaging over a 14-year period introduced any genetic variation in Ad36. We sequenced the whole genome of Ad36-which was plaque purified in 1998 from the original strain obtained from American Type Culture Collection, and passaged approximately 12 times over the past 14 years (Ad36-2012). This DNA sequence was compared with a previously published sequence of Ad36 likely obtained from the same source (Ad36-1988). Compared with Ad36-1988, only two nucleotides were altered in Ad36-2012: a T insertion at nucleotide 1862, which may induce early termination of the E1B viral protein, and a T➝C transition at nucleotide 26 136. Virus with the T insertion (designated Ad36-2012-T6) was mixed with wild-type virus lacking the T insertion (designated Ad36-2012-T5) in the viral stock. The transition at nucleotide 26 136 does not change the encoded amino acid (aspartic acid) in the pVIII viral protein. The rate of genetic variation in Ad36 is ∼2.37 × 10(-6) mutations/nucleotide/passage. Of particular importance, there were no mutations in the E4orf1 gene, the critical gene for producing obesity. This very-low-variation rate should reduce concerns about genetic variability when developing Ad36 vaccines or developing assays for detecting Ad36 infection in populations.

RESUMO

BACKGROUND: The present study was conducted to investigate the influence of different operating table heights on the quality of laryngeal view and the discomfort of the anaesthetist during enodotracheal intubation. METHODS: Eight anaesthetists participated, to each of whom 20 patients were allocated. Before induction of anaesthesia, the height of the operating table was adjusted to place the patient's forehead at one of four landmarks on the anaesthetist's body (the order being determined by block randomization with eight blocks): umbilicus (Group U), lowest rib margin (Group R), xiphoid process (Group X), and nipple (Group N). Next, the anaesthetist began the laryngoscopy and evaluated the grade of laryngeal view. For this 'initial posture', the anaesthetist was not allowed to adjust his or her posture (flexion or extension of the neck, lower back, knee, and ankle). This laryngeal view was then re-graded after these constraints were relaxed. At each posture, the anaesthetist's joint movements and discomfort during mask ventilation or intubation were evaluated. RESULTS: The laryngeal view before postural changes was better in Group N than in Group U (P=0.003). The objective and subjective measurements of neck or lower back flexion during intubation were higher in Group U than in Groups X and N (P<0.01 for each). The improvement of laryngeal view resulting from postural changes correlated with the anaesthetist's discomfort score before the postural change (P<0.01). CONCLUSIONS: Higher operating tables (at the xiphoid process and nipple level of the anaesthetist) can provide better laryngeal views with less discomfort during tracheal intubation. TRIAL REGISTRY NUMBER: NCT01649973 (clinicaltrials.gov).

RESUMO

We investigated the effects of magnesium sulphate on blood coagulation profiles using rotational thromboelastometry in patients undergoing laparoscopic colorectal cancer surgery. Patients were randomly allocated to the magnesium group (n = 22) or control group (n = 22). The magnesium group received intravenous magnesium sulphate (50 mg.kg(-1) followed by a continuous infusion of 15 mg.kg(-1) .h(-1) ), whereas the control group received the same volume of isotonic saline. Mean (SD) postoperative serum magnesium levels were 1.60 (0.13) mmol.l(-1) in the magnesium group compared with 0.98 (0.06) mmol.l(-1) in the control group (p < 0.001). All maximum clot firmness values of ROTEM analysis were significantly lower on the third postoperative day in the magnesium group compared with the control group (p < 0.05). We conclude that ROTEM analysis demonstrated that intra-operative administration of intravenous magnesium sulphate reduces blood hypercoagulability in patients undergoing laparoscopic colorectal cancer surgery.

RESUMO

Asthma is a common airway disease associated with allergic inflammation. Environmental factors, such as pollens, pollution, insect-borne antigens, or commercial chemicals, cause this disease. The common symptoms of this airway allergic reaction are increasing mucus, narrowing of the airway wall, coughing, and chest tightness. Medications, such as steroids, alleviate the disease but with severe side effects. Several studies have reported the anti-inflammatory effects of tree-based essential oil components, particularly 3-carene. Therefore, this study used 3-carene to determine if it alleviates asthmatic symptoms in the murine model. First, BALB/c mice were sensitized to an ovalbumin and aluminium hydroxide mixture on day 7th and 14th. From days 21st to 23rd, the mice were challenged with 3-carene and budesonide. The lung trachea, plasma, and bronchiolar lavage fluid (BAL fluid) were collected on day 24. The 3-carene treatment suppressed the cytokine gene expression, such as interleukin-4 (IL-4), IL-5, and IL-13, reducing the lung epithelial cell thickness in the asthmatic model. These results suggest that essential oil 3-carene has an anti-asthmatic effect.

RESUMO

BACKGROUND: Sevoflurane is widely used in paediatric anaesthesia but frequently causes emergence agitation (EA). This study evaluated whether limiting the sevoflurane concentration by combining remifentanil with sevoflurane reduced the incidence of EA. METHODS: Eighty-four preschool children scheduled for adenotonsillectomy were randomly assigned to either the remifentanil or sevoflurane group. In the remifentanil group, anaesthesia was induced with thiopental, rocuronium, and 1% sevoflurane. It was maintained with 1% sevoflurane, 60% nitrous oxide in oxygen, and a continuous infusion of remifentanil. For the sevoflurane group, anaesthesia was induced with thiopental, rocuronium, and 8% sevoflurane, and was maintained with 2-3% sevoflurane. Both groups received ketorolac 1 mg/kg and dexamethasone 0.15 mg/kg. EA was measured using the paediatric anaesthesia emergence delirium (PAED) scale and a four-point EA scale in the post-anaesthesia care unit. RESULTS: The scores on the PAED scales were significantly lower in the remifentanil group than in the sevoflurane group [median (interquartile range); 6 (4.25-10.25) vs. 11 (7.75-14.0), P = 0.007], and the proportion of patients with PAED scores ≥ 10 was significantly lower in the remifentanil group than in the sevoflurane group [15 (35.7%) vs. 27 (64.2%), P = 0.009]. The incidence of EA evaluated using the four-point scale was also lower in the remifentanil group [11 (26.1%) vs. 21 (50%), respectively, P = 0.025]. CONCLUSION: The incidence of EA was lower in children undergoing adenotonsillectomy who received a lower concentration of sevoflurane combined with remifentanil than in those given a higher concentration of sevoflurane without remifentanil.

RESUMO

Background: The rotational thromboelastogram (ROTEM) has been used in the management of massive bleeding and transfusion strategy. This study investigated ROTEM parameters measured during Cesarean section as predictors for the progression of persistent postpartum hemorrhage (PPH) in parturients with placenta previa. Methods: This prospective observational study recruited 100 women scheduled for elective Cesarean section after being diagnosed with placenta previa. Recruited women were divided into two groups according to the amount of estimated blood loss: the PPH group (PPH > 1500 ml) vs. the non-PPH group. ROTEM with laboratory tests was performed three times, preoperative, intraoperative, and postoperative time, which were compared between the two groups. Results: The PPH and non-PPH groups included 57 and 41 women, respectively. The area under the receiver-operating characteristic curve of postoperative FIBTEM A5 to detect PPH was 0.76 (95% CI = 0.64 to 0.87; P < 0.001). When postoperative FIBTEM A5 was 9.5, the sensitivity and specificity were 0.74 (95% CI = 0.55 to 0.88) and 0.73 (95% CI = 0.57 to 0.86), respectively. When subgrouping the PPH group based on the postoperative FIBTEM A5 value of 9.5, intraoperative cEBL was similar between the two subgroups; however, postoperative RBC was transfused more in the subgroup with FIBTEM A5 < 9.5 than the subgroup with FIBTEM A5 ≥ 9.5 (7.4 ± 3.0 vs 5.1 ± 2.3 units, respectively; P = 0.003). Conclusion: Postoperative FIBTEM A5, with appropriate selection of the cut-off value, can be a biomarker for more prolonged PPH and massive transfusion following Cesarean section by placenta previa.

RESUMO

OBJECTIVE: To investigate the efficacy of Gouqizi () seed oil (FLSO) on D-gal induced inflammation in testis of rats and . METHODS: In aging Sertoli cells (TM4 cells) induced by D-galactose (D-gal), the expression of upregulated aging-related proteins. The number of cells counted by cell counting kit (CCK)-8 assay showed a high number of cells disposed with FLSO at 50, 100 and 150 µg/mL compared to that for the aging model. , male Sprague-Dawley rats ( = 50, 8-week-old, 230-255 g) were randomly categorized into control, aging model, and FLSO (low-, medium-, and high-dose) groups. The expression of nuclear factor-κB (NF-κB) and its upstream factors [Janus kinase 1 (JAK1) and signal transducerand activator of transcription 1 (STAT1)] was detected by Western blot and immunofluorescence, related inflammatory factors quantified by enzyme-linked immunosorbent assay. Evaluation of testicular tissue by Johnsen score, the spermatogenic function was explored. RESULTS: The expression of interleukin-1ß (IL-1ß) ( < 0.05), IL-6 ( < 0.001), and tumor necrosis factor α (TNF-α) ( < 0.05) was decreased significantly, while that of heme oxygenase-1 (HO-1) ( < 0.001) and IL-10 ( < 0.05) was increased in cells disposed with FLSO 100 µg/mL. FLSO inhibited the expression of NF-B and declined p-p65/p65 ( < 0.01), as detected by Western blotting. In, the levels in serum of IL-1ß ( < 0.001), IL-6 ( < 0.05), and TNF-( < 0.01) declined while IL-10 ( < 0.05) was upregulated post-FLSO treatment. In addition, the expression of JAK-1 and STAT1 increased significantly in testicular tissue of rats treated with FLSO as compared to the aging model of rats ( < 0.001), while the expression of NF-κB ( < 0.001) declined in the testis in the FLSO group, as assessed by immunofluorescence. The levels of inhibor B and testosterone in serum both increased (< 0.05). CONCLUSIONS: In conclusion, this study determined the protective effects of FLSO to tolerate inflammatory injury in the testis, indicating that FLSO alleviates inflammation JAK-1/STAT1/NF-κB pathway.

RESUMO

OBJECTIVE: The objective of this study was to investigate the molecular mechanisms underlying adenovirus-36 (Ad-36)-induced obesity by the identification of novel genes and cellular pathways. DESIGN: Viral growth, intracellular lipid accumulation and gene expression profiles were determined in human mesenchymal stem cells (hMSCs) infected with Ad-36 or Ad-2. A microarray assay and gene set enrichment analysis (GSEA) were performed to assess alterations in global gene expression profiles. RESULTS: Ad-36, but not Ad-2, induced lipid accumulation and upregulated adipogenesis-related genes. There was no difference in viral growth between Ad-36 infection and Ad-2 infection in hMSCs. GSEA revealed that Ad-36 infection was more frequently associated with activation of novel pathways, including the PPAR-gamma signaling pathway, and inflammation compared with Ad-2 infection, raising the possibility that these pathways may be key regulators of Ad-36-induced adipogenesis. CONCLUSION: This study may help foster a better understanding of the roles of several cellular factors in Ad-36-induced obesity.
