Objective To evaluate the effect of electro-acupunctare at Zusanli on liver injury in a rat model of sepsis after scald.Methods Fifty SPF male Sprague-Dawley rats,weighing 200-250 g,aged 2-3 months,were randomly divided into 5 groups (n =10 each) using a random number table:control group (group C); sepsis after scald group (group SS); electro-acupuncture at Zusanli group (group E); electric stimulation of non-acupoint group (group NE); electro-acupuncture at Zusanli + α-bungarotoxin (α-BGT) group (group α-BGT).The rats were subjected to a third degree scald covering 20% of the total body surface area (TBSA) and sepsis was induced with muramyl dipeptide (MDP) 5 mg/kg injected into the femoral vein immediately after scald.Electro-stimulation (3 V,2 ms,3 Hz) of bilateral Zusanli acupoints or non-acupoints was performed for 12 min every 8 h for 2 consecutive days starting from the time point immediately after MDP was injected in group E.In group NE,electro-stimulation was performed at the points 5 mm lateral to the acupoints of bilateral Zusanli and the method was similar to those previously described in group E.In group α-BGT,α-BGT 1.0 μg/kg (in normal saline 1 ml) was injected into the femoral vein before electric stimulation,then electro-stimulation was performed and the method was similar to those previously described in group E.After 48 h of continuous stimulation,liver specimens were obtained for microscopic examination of the pathological changes.The blood samples were obtained from the abdominal aorta for determination of the levels of serum ALT and AST,tumor necrosis factor-alpha (TNF-α),and high mobility group box-1 (HMGB1) (by ELISA),and expression of Nod-like receptor 2 (NLR2) mRNA (by RTPCR) and receptor-interacting protein 2 (RIP2) in the liver tissues (by Western blot).Results The serum ALT and AST,TNF-α and HMGB-1 levels and NLR2 mRNA and RIP2 expression in liver tissues were significantly higher in SS group than in C group.Compared with SS group,the serum ALT,AST,TNF-α and HMGB1 levels were significantly decreased and NLR2 mRNA and RIP2 expression was down-regulated in E group,and no significant changes were found in the parameters mentioned above in NE group.Compared with E group,the serum ALT,AST,TNF-α and HMGB1 levels were significantly increased,and NLR2 mRNA and RIP2 expression was up-regulated in α-BGT group.The pathological changes in liver tissues were significantly reduced in group EA as compared with SS,NE and α-BGT groups.Conclusion Electro-acupuncture at Zusanli can reduce liver injury in a rat model of sepsis after scald and inhibition of NLR2/RIP2 signaling pathway and activation of cholinergic antiinflammatory pathway mediated by α7 nicotinic acetylcholine receptors in liver tissues may be involved in the mechanism.

Objective To explore the effect of irbesartan on cardiac endothelial-mesenchymal transition (EndMT) in diabetic rats.Methods The model of diabetic rat was induced by intraperitoneal injection with streptozotocin (STZ,35 mg/kg) in spontaneous hypertensive rats (SHR).Diabetic rats were divided into diabetic group and the Irbesartan treated group.The pathological changes were investigated by fluorescence microscope and electron microscope.The EndMT was studied in human aortic endothelial cells (HAEC) exposure to high glucose.The concentration of angiotensin Ⅱ in the supernatant was detected by radioimmunoassay.Immunofluorescence staining was performed to detect the co-localization of CD31 and FSP1.Results The significant myocardial fibrosis was presented in the diabetic group.Endothelial protrusions were prominent feature in myocardial microvascular of diabetic rat compared with the control group rats.Double staining of HAEC showed co-localization of CD31 and FSP1,which was decreased by the treatment of Irbesartan (P < 0.05).When HAEC was exposed to high glucose,it showed some cells acquired spindle-shaped morphology and lost CD31 staining,and FSP1 and α-SMA protein expression levels were markedly upregulated,which attenuated by the treatment of Irbesartan.Conclusion Irbesartan might prevent diabetes from myocardial fibrosis via inhibition of EndMT in diabetic rats.

Objective To discuss the clinical application of using trimmed latissimus dorsi free muscle flap together with skin grafting to resurface soft tissue defects on the dorsum of the foot. Methods From June 2005 to October 2011,eleven patients (8 males and 3 females,aged from 4-46 years) with large soft tissue defects of the foot dorsum were treated in our department. The size of the defects after debridement ranged from 5.0 cm × 6.0 cm-8.0 cm × 12.0 cm,all with exposed tendons or bones.Trimmed free latissimus dorsi muscular flap with split thickness skin grafting was used for reconstruction for all the 11 patients. Results All the flaps survived with no complications after surgery.During 3-10 months' follow-up,the appearance and walking function were satisfying, no further debulking procedures were needed. Conclusion Trimmed latissimus dorsi free flap with skin grafting is a good option for dorsal defect reconstruction.

Objective To explore the effects of cognitive behavioral intervention on fear of disease progression and negative emotionin patients with glioma.Methods A total of 60 eligible patients with glioma who were treated in neurosurgery department of the First Affiliated Hospital of Zhengzhou University from January to October 2016 were randomly divided into experimental group (n=30) and control group (n=30) according to random number table. The control group received routine care, and the experimental group patients received cognitive behavioral intervention for 12 weeks on the basis of routine care. Cognitive assessment and cognitive reconstruction were performed to achieve cognitive intervention by interviews, lectures and other forms. Behavioral intervention was achieved by musical relaxation training and personalized exercise programs for the patients. The patients were evaluated with the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) on the admission day, 1 week after surgery and 3 months after surgery to compare the fear of disease progression and negative emotion of the two groups. Results Repeated measurement analysis of variance showed that with the extension of time, the anxiety and depression scores of the two groups were decreased, and the score of the observation group was lower than that of the control group. The differences were statistically significant (P<0.05). The score of FoP-Q-SF in both groups showed a trend of rising first and then decreasing, and the peak point was as 1 week after operation. There was no statistical significant difference in the score of FoP-Q-SF between the two groups before intervention (P> 0.05). The score of the observation group was significantly lower than that of the control group at 3 months after intervention, with statistical difference (P<0.05).Conclusions There were different degrees of fear of progression and negative emotions in patients with glioma at different stages of disease. Cognitive behavioral intervention can effectively alleviate the fear of disease progression, anxiety and depression in patients with glioma, and it is worthy of clinical promotion.

Na+/H+ antiporter (NHX) gene subfamily plays an important role in plant response to salt stress. In this study, we identified the NHX gene family members of Chinese cabbage and analyzed the expression patterns of BrNHXs gene in response to abiotic stresses such as high temperature, low temperature, drought and salt stress. The results showed that there were 9 members of the NHX gene family in Chinese cabbage, which were distributed on 6 chromosomes respectively. The number of amino acids was 513-1 154 aa, the relative molecular weight was 56 804.22-127 856.66 kDa, the isoelectric point was 5.35-7.68. Members of BrNHX gene family mainly existed in vacuoles, the gene structure is complete, and the number of exons is 11-22. The secondary structures of the proteins encoded by the NHX gene family in Chinese cabbage had alpha helix, beta turn and random coil, and the alpha helix occurred more frequently. Quantitative real-time PCR (qRT-PCR) analysis showed that the gene family members had different responses to high temperature, low temperature, drought and salt stress, and their expression levels differed significantly in different time periods. BrNHX02 and BrNHX09 had the most significant responses to these four stresses, and their expression levels were significantly up-regulated at 72 h after treatments, which could be used as candidate genes to further verify their functions.
