Objective To explore the effect of early comprehensive rehabilitation care on the quality of rehabilitation of severe viral encephalitis children.Methods Totals of 120 children with severe viral encephalitis were selected between January 2011 and September 2011 as the intervention group received comprehensive rehabilitation care in early stage of the disease.And 105 children with severe viral encephalitis between January 2008 and September 2008 as the control group received routine nursing.Their treatment efficiency,Glasgow score,Fugl -Meyer score,EEG and average hospitalization days were observed in two groups.Results General effective rate was 95.8％ of intervention group and 82.9％ of the control group,and the difference was statistically significant( x2 =30.94,P＜0.01).Glasgow score and Fugl-Meyer score of intervention group was significantly higher than that of control group (P ＜0.05).As the intervention group had higher recovery rate and fewer hospitalization days than that of control group.Conclusions Early introduction of comprehensive rehabilitation for children of sever viral encephalitis can effectively promote their recovery and improve the quality of recovery.

OBJECTIVETo investigate the antimicrobial resistance of clinical isolates of Stenotrophomonas matophilia (SMA) and the mechanisms of their drug resistance.

METHODSDisc diffusion method (NCCLS) was used to detect the resistant patterns of 88 initial SMA isolates resistant to 12 antibiotics isolated from a local hospital in the past 4 years. PCR was used to detect the 7 aminoglycosides modifying enzymes genes (AME) against amikacin and gentamicin. Metal-beta-lactamases (MBLs) were screened by synergic method, and extended-spectrum beta-lactamases (ESBLs) were detected by double-disk synergy test.

RESULTSThe resistance rates of the SMA isolates were 0%-9.7% to minocycline, 12.5%-22.6% to ticarcillin-clavulanic acid, 12.5%-28.6% to levofloxacin, 18.8%-33.3% to doxycycline, 18.8%-40% to sulfamethoxazole compound, 50%-65.7% to ciprofloxacin, 50%-66.7% to cehazindme, 54.8%-66.7% to amikacin, 75%-100% to gentamicin, 81.3%-100% to piperacillin, 87.5%-100% to aztreonam and 93.5%-100% to imipenem. Aac(3)-I and ant(4')-II were not detected in these strains. The positive rates of the other 5 AME genes of aac(3)-II, ant(2'')-I, aac(6')-I, aac(3)-III, aac(3)-IV were 2.3%, 5.7%, 8%, 10%, and 10%, respectively. SMA strains producing ESBLs were found at the rate of 38.6%; 25% of the strains were MBL-producing, and 13.6% produced both ESBLs and MBLs.

CONCLUSIONMost of the SMAs we isolated are multidrug-resistant through various mechanisms. The choice of antibiotics should be made according to the susceptibility results.

OBJECTIVETo investigate the methods and conditions for the isolation, purification and culture of human spermatogonial stem cells (SSCs) on the feeder layer cells of human embryonic fibroblasts (hEFs).

METHODSSSCs isolated and purified from normal human fetal testicular tissues by sequential two-step enzyme digestion and Percoll uncontinuous density gradient centrifugation were cultured on the feeder layer cells of hEFs isolated from 5-9 weeks old human embryos. The surface markers SSEA-1 and OCT4 of the SSCs were detected by immunohistochemistry; the alkaline phosphatase (AKP) activity of the SSC clones measured; and the expressions of the SSC-related genes determined by RT-PCR.

RESULTSSSCs survived, proliferated and formed colonies on the feeder layers, and the colonies were highly positive for SSEA-1 and OCT4, with strong AKP activity and high expressions of the SSC-related genes.

CONCLUSIONThe feeder layer of hEFs supports the growth of human spermatogonial stem cells.

OBJECTIVE: To investigate the inflammatory effects of Cinobufotalin on monocytes in resting state and macrophages in activated state and its molecular mechanism. METHODS: THP-1 cells were stimulated with Phorbol 12-myristate 13-acetate to induce differentiation into macrophages. Lipopolysaccharides was added to activate macrophages in order to establish macrophage activation model. Cinobufotalin was added to the inflammatory cell model for 24 h as a treatment. CCK-8 was used to detect cell proliferation, Annexin V /PI double staining flow cytometry was used to detect cell apoptosis, flow cytometry was used to detect macrophage activation, and cytometric bead array was used to detect cytokines. Transcriptome sequencing was used to explore the gene expression profile regulated by Cinobufotalin. Changes in the significantly regulated molecules were verified by real-time quantitative polymerase chain reaction and Western blot. RESULTS: 1∶25 concentration of Cinobufotalin significantly inhibited the proliferation of resting monocytes(P<0.01), and induced apoptosis(P<0.01), especially the activated macrophages(P<0.001, P<0.001). Cinobufotalin significantly inhibited the activation of macrophages, and significantly down-regulated the inflammatory cytokines(IL-6, TNF-α, IL-1β, IL-8) released by activated macrophages(P＜0.001). Its mechanism was achieved by inhibiting TLR4/MYD88/P-IκBa signaling pathway. CONCLUSION Cinobufotalin can inhibit the inflammatory factors produced by the over-activation of macrophages through TLR4/MYD88/P-IκBa pathway, which is expected to be applied to the treatment and research of diseases related to the over-release of inflammatory factors.

Objective: To explore the association between cardiometabolic diseases (CMD) and quality of life, the association between CMD and perceived stress, and the mediation effect of perceived stress on the association between CMD and quality of life, and to provide evidence for the prevention and treatment of CMD and the improvement of quality of life in these patients. Methods: This is a cross-sectional study. Data were collected by the employees' physical examination of a company in Xi'an in 2021. Multiple linear regression models were used to analyze the association between the status of CMD (divided into three categories: no CMD, presence of one kind of CMD, and with≥2 kinds of CMD (≥2 kinds of CMD were defined as cardiometabolic multimorbidity (CMM)), quality of life, and perceived stress. Mediation analysis with a multi-categorical independent variable was conducted to determine the mediation effect of perceived stress on the association between CMD and quality of life. Results: Among all 4 272 participants, 1 457 (34.1%) participants had one kind of CMD and 677 (15.8%) participants had CMM. The average scores for quality of life and perceived stress were (57.5±15.7) and (16.9±7.9), respectively. Compared with participants without CMD, after adjusting for demographic and lifestyle factors, no statistically significant associations were observed between one kind of CMD and perceived stress or quality of life (both P>0.05). Perceived stress did not mediate the association between one kind of CMD and quality of life. However, participants with CMM had lower quality of life and higher perceived stress than participants without CMD. The relative total effect coefficient c (95%CI) and the relative direct effect coefficient c' (95%CI) between CMM and quality of life were -3.71 (-5.04--2.37) and -2.52 (-3.81--1.24) (both P<0.05), respectively. The relative indirect effect coefficient a₂b (95%CI) of perceived stress on the association between CMM and quality of life was -1.18 (-1.62--0.77) (P<0.05). The mediation effect size was 31.8%. Conclusions: CMM is negatively associated with quality of life and positively associated with perceived stress. Perceived stress partially mediates the association between CMM and quality of life. Our results suggest that, in addition to preventing and treating CMM actively, efforts should be taken to relieve the perceived stress of people with CMM to improve their quality of life.
