Abstract
DExD/H-box helicases are crucial regulators of RNA metabolism and antiviral innate immune responses; however, their role in bacteria-induced inflammation remains unclear. Here, we report that DDX5 interacts with METTL3 and METTL14 to form an m6A writing complex, which adds N6-methyladenosine to transcripts of toll-like receptor (TLR) 2 and TLR4, promoting their decay via YTHDF2-mediated RNA degradation, resulting in reduced expression of TLR2/4. Upon bacterial infection, DDX5 is recruited to Hrd1 at the endoplasmic reticulum in an MyD88-dependent manner and is degraded by the ubiquitin-proteasome pathway. This process disrupts the DDX5 m6A writing complex and halts m6A modification as well as degradation of TLR2/4 mRNAs, thereby promoting the expression of TLR2 and TLR4 and downstream NF-κB activation. The role of DDX5 in regulating inflammation is also validated in vivo, as DDX5- and METTL3-KO mice exhibit enhanced expression of inflammatory cytokines. Our findings show that DDX5 acts as a molecular switch to regulate inflammation during bacterial infection and shed light on mechanisms of quiescent inflammation during homeostasis.

Abstract
Radiation therapy is the first choice for the treatment of nasopharyngeal carcinoma. However, it is inevitable that nasopharyngeal mucosa and tissue will be damaged after radiotherapy of nasopharyngeal carcinoma, which will cause corresponding complications. Nasopharyngeal osteonecrosis is a serious complication. Up to now, there are few reports about nasopharyngeal osteonecrosis, and the underlaying pathological mechanism remains unclear. The potential theories include radiotherapy damage, infection and trauma, but also the " three H" principle of hypoxic hypocellular hypovascular tissue, as well as the theory of radio induced fibrosis. It is controversial about the treatment of nasopharyngeal osteonecrosis. It takes comprehensive treatment, including local treatment, systemic treatment, surgical treatment and other treatments. Among them, local treatment as nasopharyngeal debridement usually is first choice. We reviewed the pathological mechanism and treatment methods of nasopharyngeal osteonecrosis, in order to provide a reference for better prevention and treatment of it.

Abstract
The dose-limiting side effect of the anti-neoplastic agent, paclitaxel, is a chronic distal symmetrical peripheral neuropathy that produces sensory dysfunction (hypoesthesia and neuropathic pain) but little or no distal motor dysfunction. Similar peripheral neuropathies are seen with chemotherapeutics in the vinca alkaloid, platinum-complex, and proteasome inhibitor classes. Studies in rats suggest that the cause is a mitotoxic effect on axonal mitochondria. If so, then the absence of motor dysfunction may be due to mitotoxicity that affects sensory axons but spares motor axons. To investigate this, paclitaxel exposure levels in the dorsal root, ventral root, dorsal root ganglion, peripheral nerve, and spinal cord were measured, and the ultrastructure and the respiratory function of mitochondria in dorsal roots and ventral roots were compared. Sensory and motor axons in the roots and nerve had comparably low exposure to paclitaxel and exposure in the spinal cord was negligible. However, sensory neurons in the dorsal root ganglion had a very high and remarkably persistent (up to 10 days or more after the last injection) exposure to paclitaxel. Paclitaxel evoked a significant increase in the incidence of swollen and vacuolated mitochondria in the myelinated and unmyelinated sensory axons of the dorsal root (as seen previously in the peripheral nerve) but not in the motor axons of the ventral root. Stimulated mitochondrial respiration in the dorsal root was significantly depressed in paclitaxel-treated animals examined 2-4 weeks after the last injection, whereas respiration in the ventral root was normal. We conclude that the absence of motor dysfunction in paclitaxel-evoked peripheral neuropathy may be due to the absence of a mitotoxic effect in motor neuron axons, whereas the sensory dysfunction may be due to a mitotoxic effect resulting from the primary afferent neuron's cell body being exposed to high and persistent levels of paclitaxel.

Abstract
A novel loop-mediated isothermal amplification (LAMP) assay was established to detect Brucella species DNA in milk and blood samples of animals and humans. This LAMP assay based on the sequence of highly repetitive omp25 gene was able to detect 9fg/μl Brucella spp. DNA with high sensitivity, which was 10 times higher than the nested PCR. The LAMP was evaluated for its specificity using 19 strains of six Brucella species and 28 related non-Brucella micro-organism strains as controls. The target 19 Brucella strains were all amplified, and no cross-reaction was found with all the non-Brucella micro-organism strains. Both nested PCR and LAMP assays were then used to detect Brucella spp. DNA in 78 milk samples and 113 blood samples from animals and 11 blood samples from humans, and the established LAMP assay yielded 99.0% concordance rate with the nested PCR. The LAMP assay should be a potential tool with high convenience, rapidity, sensitivity and specificity for the diagnosis of Brucellosis.

Abstract
An indirect ELISA for the serological detection of bovine ephemeral fever virus (BEFV) infection in cattle is described in which a glycosylated protein of approximately 25 kDa (including the G1 antigenic site of the virus glycoprotein) expressed in Pichia pastoris GS115 was used as the coating antigen. The optimal concentration of coated antigen was 0.3 microg/well at a serum dilution of 1:40. The optimal positive threshold value of the assay was 1.88, as derived from receiver operating characteristic curve analysis. The test had 100% sensitivity and 96.7% specificity when compared with a micro-neutralisation test using 336 positive and 180 negative sera to BEFV, respectively. The inter-assay and intra-assay coefficients of variation for 15 sera were both <5.8% and there was no evidence of cross-reactivity between the tested coating antigen and antibodies to related rabies virus. The ELISA is an inexpensive and rapid serological detection method that would be suitable for screening for BEFV infection on a large scale.

Abstract
There is no clear consensus on the advantages of laparoscopically assisted surgery (LAS) versus open surgery (OS) for endometrial cancer. The present study compared LAS versus OS for patients with endometrial cancer with regard to operative parameters and outcomes. A search of the PubMed, EMBASE, the China Biological Medicine Datadase (CBMdisc), Ovid, and the Cochrane Library identified four studies that met the inclusion criteria for data extraction. Estimates of effectiveness were performed using fixed- and random effects models. The effect was calculated as an odds ratio (OR) or weighted mean difference (WMD) with 95% confidence intervals (CIs). Level of significance was set at P < 0.05. Outcomes of 331 patients were studied. When randomized controlled trials were analyzed, OR for LAS was 0.34 (95% CI: 0.13, 0.89; P = 0.03) for postoperative complications and 0.14 (95% CI: 0.05, 0.39; P = 0.0002) for incidence of transfusion; and WMD for LAS was 263.58 mL (95% CI: 467.71, 59.45 mL; P = 0.01) for blood loss, 38.09 min (95% CI: 10.50, 65.68 min; P = 0.007) for operation time, and 3.35 days (95% CI: 3.84, 2.86 days; P < 0.00001) for hospital stay. There was no difference in patients in terms of recurrence and survival. The present study has shown that LAS was associated with fewer postoperative complications, lower incidence of transfusion, less blood loss, longer operation time, and shorter hospital stay. What's more, no significant difference was found in terms of recurrence and survival. When performed by suitably specialized surgeons in selected patients, it appears to be a better choice than OS.

Abstract
Subjects with genital warts were immunized three times or more with HPV6b VLPs without adjuvant. All immunized subjects had DTH to HPV6b L1 protein. Of 32 subjects, nine had HPV6b specific antibody prior to immunization and 22 acquired antibody with immunization. VLP specific antibody increased following a single immunization in 6 of 8 subjects with low level antibody at recruitment. Complete regression of genital warts was observed in 25 of 33 evaluable subjects over the 20-week observation period. We conclude that immunization with HPV6b L1 VLPs without adjuvant induces immunity to the L1 protein epitopes recognised during natural infection, and may accelerate regression of warts.
