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.

OBJECTIVETo observe the effects of panax quinquefolius saponin (PQS) of stem and leaf on glucose-lipid metabolism and insulin signal transduction in the insulin resistant model of adipocytes.

METHODSThe insulin resistant model of differentiated 3T3-L1 adipocytes was established in vitro with free fatty acid. After induction of insulin resistance, cells were treated with metformin or PQS for 2 days. The glucose consumption in culture fluid was detected by glucose oxidase method; the effects of PQS on the lipolysis induced by tumor necrosis factor (TNF-alpha) was observed using colorimetry; and the phospholation of signal proteins was detected by Western-blot.

RESULTSThe amount of glucose consumption (mmol/L) in the model group (5.250 +/- 2. 671) was significantly lower than that in the normal control group (14.133 +/- 1.305, P < 0.01), it increased in the meformin treated group (11.807 +/- 1.358), and the groups treated with high-, middle- and low-dose PQS dose-dependently (10.784 +/- 2.373, 10.217 +/- 1.237 and 9.984 +/- 2.006, respectively), significantly higher than that in the model group (P < 0.01). Upon TNF-alpha treatment, the concentration of free fatty acid (FFA) (nmol/ microg) in culture medium was 2.479 +/- 0.597, predominantly higher than that in the control group (1.320 +/- 0.538, P < 0.01), while it was 1.210 +/- 0.566 in the metformin group, 1.105 +/- 0.631 in high-dose PQS group, 1.108 +/- 0.260 in the middle-dose PQS group, 1.201 +/- 0.593 in the low-dose PQS group, all were lower than that in the TNF-alpha group (P < 0.05 or P < 0.01), and a dose-dependent tendency of PQS's action was seen. The tyrosine phosphorylation of insulin receptor and IRS-1 as well as Ser473 phosphorylation of PKB were lower in the model group than in the control group; they were insignificantly changed in the low-dose PQS group, but did show significant difference in comparing with those in the high-and middle-dose PQS groups or metformin group.

CONCLUSIONPQS can accelerate the glucose utilization and depress the lipolysis in adipocytes induced by TNF-alpha, which may be correlated with its promoting insulin signal transduction and improving insulin resistance in adipocytes.

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.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.
