BACKGROUND: Cardiac arrest (CA) is a critical condition that is a concern to healthcare workers. Comparative studies on extracorporeal cardiopulmonary resuscitation (ECPR) and conventional cardiopulmonary resuscitation (CCPR) technologies have shown that ECPR is superior to CCPR. However, there is a lack of studies that compare the protective effects of these two resuscitative methods on organs. Therefore, we aim to perform experiments in swine models of ventricular fibrillation-induced CA to study whether the early application of ECPR has advantages over CCPR in the lung injury and to explore the protective mechanism of ECPR on the post-resuscitation pulmonary injury. METHODS: Sixteen male swine were randomized to CCPR (CCPR; n=8; CCPR alone) and ECPR (ECPR; n=8; extracorporeal membrane oxygenation with CCPR) groups, with the restoration of spontaneous circulation at 6 hours as an endpoint. RESULTS: For the two groups, the survival rates between the two groups were not statistically significant (P>0.05), the blood and lung biomarkers were statistically significant (P<0.05), and the extravascular lung water and pulmonary vascular permeability index were statistically significant (P<0.01). Compared with the ECPR group, electron microscopy revealed mostly vacuolated intracellular alveolar type II lamellar bodies and a fuzzy lamellar structure with widening and blurring of the blood-gas barrier in the CCPR group. CONCLUSIONS: ECPR may have pulmonary protective effects, possibly related to the regulation of alveolar surface-active proteins and mitigated oxidative stress response post-resuscitation.

OBJECTIVETo observe the clinical efficacy on fibromyalgia syndrome treated with acupuncture at the acupoints selected from the affected meridians based on the location differentiation and the heavy moxibustion at painful points by the randomized controlled trial with medication.

METHODSThirty-two patients of fibromyalgia were randomized into an acupuncture-moxihustion group and a medication group, 16 cases in each one. In the acupuncture-moxibustion group, acupuncture at the acupoints selected from the affected meridians based on the location differentiation and the heavy moxibustion at painful points were applied, once every two days, three times a week, for 4 weeks totally. In the medication group, tramadol sustained release tablets and amitriptyline were prescribed for oral administration, once a day, for 4 weeks. The follow-up visit was conducted for 4 weeks in the two groups. Before and after treatment and in follow-up visit, the revised version of the fibromyalgia impact questionnaire (FIQR) and visual analogue scale (VAS) were adopted for assessment and comparison of the efficacy between the two groups.

RESULTSAfter treatment and in follow-up visit, FIQR score and VAS score were improved apparently as compared with those before treatment in the two groups (all P<0. 05). At the end of treatment, the differences were not significant statistically between the two groups (all P>0. 05). But the differences were significant in follow-up visit (all P<0. 05). The scores in the acupuncture-moxibustion group were improved persistently, but those in the medication group were rebound.

CONCLUSIONThe acupuncture at the acupoints selected from the affected meridians based on the location differentiation and the heavy moxibustion at painful points are safe and effective in the treatment of fibromyalgia syndrome and present the better persistent effect as compared with the combined medication of tramadol sustained release tablets and amitriptyline.

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus Tanbo-plucking the trigger points for scapulohumeral periarthritis (SP). Methods:A total of 80 patients with SP were randomized into an observation group and an EA group by the random number table, with 40 cases in each group. The EA group was treated with EA therapy, and the observation group was treated with EA therapy plus Tanbo-plucking the trigger points. After treatment, the visual analog scale (VAS) and Melle scores of the two groups were compared to evaluate the improvement of shoulder pain and functional activity, and meanwhile the clinical efficacy was observed. Results: After treatment, the total effective rate of the observation group was 95.0％ and the cure and markedly effective rate was 72.5％. The total effective rate of the EA group was 87.5％ and the cure and markedly effective rate was 42.5％. There was no significant difference in the total effective rate between the two groups (P>0.05). The cure and markedly effective rate of the observation group was higher than that of the EA group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the intra-group differences in VAS and Melle scores of both groups were statistically significant (bothP<0.001). The inter-group differences in the changes of the VAS and Melle scores after treatment were statistically significant (bothP<0.001). Conclusion: EA plus Tanbo-plucking the trigger points has a better curative effect than EA therapy alone in the treatment of SP.

Objective To predict the biological process and signaling pathways in which hsa-miR-1908 might be in-volved by a series of bioinformatics analysis, so as to lay foundations and provide theoretical basis for the further studies of hsa-miR-1908 biological function in human preadipocytes. Methods The sequence of hsa-miR-1908 was acquired from miR-Base database, and target genes of hsa-miR-1908 were predicted by miRanda, and then the intersection of the results and the results of gene-chip as gene set were further analyzed by gene ontology and pathway enrichment. Results The hsa-miR-1908 had some conserved property among different species. The functions of the target genes were enriched in Wnt receptor signal-ing pathway through beta-catenin, cell cycle, cell apeptosis and other biological processes. The GnRH signaling, MAPK sig-naling, insulin signaling, cell cycle signal transduction pathways and signaling pathway in pancreatic cancer were signiifcantly enriched. Conclusions The target genes set of hsa-miR-1908 were enriched in multiple biological process which are related with the obesity. This study provides guidance for the further study in human preadipocytes.

Objective To investigate the inlfuence of overexpression of miR-26b on the secretion of adipokines dur-ing human adipocyte differentiation. Methods Human preadipocytes were infected with the hsa-miR-26b over-expressing lentivirus and were induced to differentiate, and then the levels of adipokines (IL-6, leptin, resistin, TNF-α) at different time points during differentiation were measured by ELISA. Results Compared with control group, decreased secretions of both IL-6 and leptin, and increased secretion of resistin were found during the differentiation of human adipocytes in miR-26b overexpressed group. However, the secretion of TNF-αwas not measured in both groups. Conclusion The miR-26b can improve the inlfammation and insulin resistance of human adipocytes, which will provide potential targets for obesity treat-ment.

Objective To study the effect of glucose regulated protein 75(Grp75) on the alteration of Bax and NF-κB induced by glucose deprivation through the stably transfected PC12 cells with Grp75. Methods The cells of Grp75-overexpressing group and control group incubated in glucose-free DMEM medium for indicated time (6, 12, 24 and 48hours). The expression level of Grp75, Bax and the activity of NF-κB were determined by Western blotting, and the expression level of Bax was determined by semi-quantitative RT-PCR and Western blotting. Immunocytochemistry was performed using a conformation specific anti-Bax (6A7) antibody to detect the activation of Bax. Results The activation of Bax and the decline of NF-κB activity played important roles in the apoptosis of PC12 cells induced by glucose deprivation. Grp75 inhibited the apoptosis induced by glucose deprivation through inhibition of the activation of Bax and the decline of NF-κB activity. There was no change in Bax expression level under glucose deprivation in two groups. Conclusion The activation of Bax and the decline of NF-κB activity were associated with apoptosis of PC12 cells induced by glucose deprivation, and Grp75 provided protection to PC12 cells through inhibition of activation of Bax and maintaining activation of NF-κB.
