Objective To explore the effect RNAi-mediated inhibition of X-linked inhibit apoptosis protein (XIAP) gene on apoptosis and susceptibility to chemical therapy drugs in osteosarcoma cells and its underlying mechanism.Methods shRNA plasmid of XIAP gene were constructed. MG63 cells were conventionally cultured and divided into untreated group (group A,non-transfection),blank plasmid group (group B,psiRNA-Con transfected),the experimental group (group C,psiRNA-XIAP transfected),and 2 chemical drug interfered groups,non-transfection+0.3 ?mol Dox group (A+Dox group) and psiRNA-XIAP transfection +0.3 ?mol Dox group (C+Dox group). The XIAP expression in MG63 cells was detected by Western blotting. The proliferation of above-mentioned MG63 cells was examined by MTT assay. Flow cytometry (FCM) was employed to detect the cell apoptosis,cell cycle and Caspase-9 expression. Results Group C had a significantly lower protein level of XIAP and MTT value than group A and B (P

Riboswitch is a novel type of posttranscriptional regulatory elements discovered by Breaker et al. in 2002. It can regulate gene expression by binding directly to small metabolites without the aid of protein molecules. Compared to normal protein-mediated regulation, riboswitch responds to metabolites more rapidly and sensitively. Its discovery opens a new world for RNA research. The recent advances in riboswitch researches were summarized, including crystal structure determination, mechanism and dynamics study, biosensor and antibacterial drug design. Topp et al. successfully reprogrammed E. coli to detect, follow, and precisely localize to a completely new chemical signal by using a synthetic riboswitch. This work provided new ideas for synthetic biology and artificial biology network. The advances in riboswitch 3D structure determination, reaction mechanism and dynamics provide useful information for rational drug design towards new generation of riboswitch-targeting antibacterials.

Objective To investigate the differential expression of synaptophysin(SYN)in the developing rat cochlea,to analyze the relationship between the expression of SYN and auditory functional development,and to explore the source of the adenosine triphosphate(ATP)in the cochlea.Methods The immunofluorescence was applied to observe the differential expression of SYN in the cochlea of SD rats on different days(p1,p5,p10,p14 and p28)after parturition.Results No significant stain was observed in the Kolliker organ or the Corti's organ of P1,P5 and the top turn of the cochlea in P10.The SYN expression was turned on the outer spiral bundle,the inner spiral bundle,and the medial wall of the Deiters' cell of the cochlea in P14,P28 and the second or the third turn of Corti's organ of P10.All the spiral ganglion neurons(SGN)were stained in different aged cochlea.Conclusion The expression of SYN was different during development of rat cochlea.This difference was in favor of the configuration constructed between nerve endings and target cells.It also played a key role in the formation of correct auditory coding during auditory system development.The hair cells and the supporting cells,possible the source of ATP in the cochlea,contained ATP that maybe existed in a non-vesicular form or specific staining of non-SYN.

Objective To evaluate the morphological changes of the small nerves in lower extremity with high-resolution ultrasonography in type 2 diabetes mellitus (T2DM). Methods 84 cases of T2DM patients were divided into four different groups according to TCSS score [group Ⅰ (0-5 point), group Ⅱ (6-8 point), groupⅢ (9-11 point), group Ⅳ (12-19 point)]. The ultrasonic feature of posterior tibial nerve, sural nerve and saphenous nerve were observed to observe the relationship between ultrasound findings and scoring. Results Abnormality rate admitted from ultrasound findings are as follows. In group Ⅳ, nerve abnormality rate was the highest, followed by group Ⅲ, group Ⅱ and group Ⅰ (P < 0.05). The major manifestations are obscure border between spineurium and peripheral tissue , nerve bundle mesh like structure disappearing , enlargement of posterior tibial nerve and sural nerve. There was no statistical difference in irregular abnormality rate (P > 0.05). The saphenous nerve epineurium abnormality increased in group Ⅱ and Ⅲ compared with group Ⅰ and Ⅳ(P <0.05). Abnormality rate of 3 neural ultrasound decreased in line with sural nerve, posterior tibial nerve and saphenous nerve. Conclusions Certain correlation was observed between TCSS and never ultrasonic feature in T2DM patients. The higher TCSS scores is, the greater chance of presence of abnormal sonographic features of nerves will be. The sural nerve abnormality was higher than others.

Abstract： Objective　To analyze the changes of cytokine levels in patients with sensitive pulmonary tuberculosis and drug-resistant pulmonary tuberculosis before and after anti-tuberculosis treatment. Methods　The clinical data of 213 pulmonary tuberculosis patients admitted to the Eighth Affiliated Hospital of Xinjiang Medical University from August 2019 to October 2020 were collected, and divided into a sensitive pulmonary tuberculosis group and a drug-resistant pulmonary tuberculosis group, of which 141 were in the sensitive group and 72 in the drug-resistant group , and the pro-inflammatory factors tumor necrosis factor-α (TNF-α), IL-6, IL-17, interferon-γ (IFN-γ) and anti-inflammatory factors IL-10 and IL-4 in plasma before treatment, 3 months and 6 months after treatment were compared. Results　Compared with the healthy group, the levels of plasma IL-6 in the sensitive group and the resistant group were significantly increased, difference was statistically significant (P<0.01). The plasma levels of IFN-γ and IL-17 in the sensitive group were increased, and the difference was statistically significant (P<0.05). Compared with before treatment, the levels of IL-6 and IL-4 in the plasma of the sensitive group after 6 months of treatment were lower than those after 3 months of treatment, and the difference was statistically significant (P<0.05), and IFN-γ was significantly decreased (P<0.001). After 6 months of treatment, the IL-10 content was lower than that before treatment, and the difference was statistically significant (P<0.05), and the IFN-γ decreased significantly (P<0.000 1). The levels of IFN-γ at 3 months were higher than those in the resistant group, and the difference was statistically significant (P<0.01). After 6 months of treatment, there was no significant difference in the content of IFN-γ between the sensitive group and the resistant group. The effective rate of CT absorption was 70% in the sensitive group and only 43.33% in the resistant group at 3 months of treatment, and there was no significant difference in the effective rate between the two groups after 6 months of treatment. Conclusions　Detection of pro-inflammatory cytokines and anti-inflammatory cytokines in plasma can provide reference for host-directed therapy of pulmonary tuberculosis. Understanding this important feature of cytokines on pathogen-host interactions can provide new insights into the study of virulence mechanisms and may provide new approaches for immune intervention in pulmonary tuberculosis.
