Objective To investigate the effects of mitochondrial division inhibitor 1 (mdivi-1) in rats after cardiopulmonary resuscitation (CPR) and its mechanism.Methods Fifty Sprague-Dawley (SD) rats were randomly (random number table) divided into sham group (n =8),cardiac arrest (CA) model group (n =14),dimethyl sulfoxide post-treatment control group (DMSO group,n =14),and mdivi-1 post-treatment group (mdivi-1 group,n =14).Asphyxial CA was reproduced in animals,and they were resuscitated by CPR.In the mdivi-1 group or DMSO group,the animals were given mdivi-1 (1.2 mg/kg) or DMSO (0.1％) intravenously after restoration of spontaneous circulation (ROSC).The neurological functions were assessed using neurological deficit score (NDS) determined at 24,48 and 72 hours after CPR.The brain tissues were harvested at 72 hours after CPR.The histopathologic changes were assessed by hematoxylin and eosin (HE) staining,and the normal neuron was counted.The neuronal apoptosis was assessed with terminal dexynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining,and the expressions of cytochrome C (Cyt-C) protein in mitochondria and cytoplasm from hippocampus were determined by Western Blot.Results NDS in all experiment groups was gradually increased after CPR,and they were significantly lower than thoseo.f the sham group at 24,48,and 72 hours (51.5±3.7 vs.80.0±0.0,59.3±3.6 vs.80.0±0.0,66.7±2.6 vs.80.0±0.0,all P ＜ 0.05).The number of normal pyramidal neurons in the hippocampal CA1 region was markedly reduced (cells/HP:4.4± 1.1 vs.23.1 ± 4.0,P ＜ 0,05),the apoptotic index was significantly increased [(86.9 ± 6.9)％ vs.(3.4 ± 0.8)％,P ＜ 0.05],the expressions of Cyt-C in mitochondria were significantly decreased (A value:0.46±0.18 vs.1.00±0.00,P ＜ 0.05),and the expressions of Cyt-C in cytoplasm were significantly up-regulated (A value:6.65±0.21 vs.1.00±0.00,P ＜ 0.05).Compared with the CA group,NDS at 24 hours and 48 hours in mdivi-1 group was slightly increased (55.2 ± 3.3 vs.51.5 ± 3.7,64.7 ± 2.4 vs.59.3 ± 3.6,both P ＞ 0.05),and it was significantly increased at 72 hours (74.5±2.3 vs.66.7 ± 2.6,P ＜ 0.05),the number of normal pyramidal neurons in the hippocampal CA1 region was markedly increased (cells/HP:16.2±2.4 vs.4.4± 1.1,P ＜ 0.05),the apoptotic index was dramatically reduced [(42.3 ± 3.9)％ vs.(86.9 ± 6.9)％,P ＜ 0.05],the expressions of Cyt-C in mitochondria were significantly increased (A value:0.83 ± 0.22 vs.0.46 ± 0.18,P ＜ 0.05),and the expressions of Cyt-C in cytoplasm were significantly decreased (A value:3.84±0.47 vs.6.65±0.21,P ＜ 0.05).There was no statistically significant difference in above indexes between CA group and DMSO group.Conclusion By inhibiting mitochondrial Cyt-C apoptotic pathway to reduce neuronal apoptosis in rats after CA-CPR,mdivi-1 can improve brain function after CPR.

BACKGROUND:Bone marrow mesenchymal stem cel s are likely to repair renal injury by differentiating into renal parenchymal cel s. OBJECTIVE:To explore the effect and mechanism of bone marrow mesenchymal stem cel s in the renal repair after mesangial proliferative glomerulonephritis. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and treatment group (n=10 per group). Model group and treatment group were treated with tail vein injection of mouse anti-rat monoclonal antibody Thy1.1 to prepare mesangial proliferative glomerulonephritis models. One week after modeling, rats in the treatment group were given 2×106 bone marrow mesenchymal stem cel s via the tail vein, and rats in the other two groups were given the same volume of normal saline. Two weeks after transplantation, urinary protein, urea nitrogen, creatinine levels were detected;hematoxylin-eosin staining was used for observing pathological changes of the renal tissue under microscope;and the expression of transforming growth factor beta 1 was detected by immunohistochemistry method. RESULTS AND CONCLUSION:The levels of urinary protein, urea nitrogen and creatinine as wel as the expression of transforming growth factor beta 1 in the renal tissue arranged in descending order were listed as fol ows:model group>treatment group>control group, and there were significant differences among three groups (P<0.05). In the model group, diffuse glomerular hyperplasia was observed with the presence of increased extracel ular matrix, partial glomerular sclerosis, and interstitial infiltration of inflammatory cel s;in the treatment group, glomerular hyperplasia, mesangial proliferation and inflammatory cel infiltration were al mitigated compared with the model group. Therefore, bone marrow mesenchymal stem cel transplantation may contribute to renal repair after mesangial proliferative glomerulonephritis, by inhibiting overexpression of transforming growth factor beta 1 in the kidney.

Objective To study the relationship between essential hypertension(EH)with serum homocysteine(HCY),uroten-sinⅡ(UⅡ),angiotensin converting enzyme(ACE)and N-terminal pro-brain natriuretic peptide(NT-proBNP).Methods By collec-ting the clinical cases,UⅡwas determined by ELISA and HCY,ACE and NT-proBNP were simultaneously detected by ELISA.The detection results were analyzed and compared between the patients with essential hypertension(EH group)and the healthy con-trols.Results The levels of serum HCY,UⅡ,ACE and NT-proBNP in the EH group were significantly increased compared with the healthy control group;the area under curve (AUC)of serum HCY,UⅡ,ACE and NT-proBNP in the ROC curve in the EH group were 0.93,0.765,0.792 and 0.972 respectively,which showed clinical diagnostic significance.Conclusion The levels of HCY,UⅡ,ACE and NT-proBNP are highly expressed in EH and have significant differences compared with the healthy popula-tion,which has the diagnostic value to EH.

Objective:To evaluate the clinical effects of invisible bracketless appliance on the upper molar distalization.Methods:15 patients with class Ⅱ malocclusion(at the average age of 25.3 years) were treated by invisible bracketless appliance,the pre and post three-dimensional digital models were superimposed and measured,the effects of molar distalization were analysed.Results:After treatment,the maxillary first molars were distalized by 2.58 mm on both sides.The left and fight second molars were distalized by 2.57 mm and 2.68 mm respectively.Bilateral central incisors were moved mesially by 0.34 mm.There was no significant difference in the horizontal movement of central incisor.But the left and fight first molars were moved buccally by 0.96 mm and 0.97 mm respectively,the left and fight second molars were moved buccally by 1.01 mm and 1.11 mm separately.Bilateral first molars were intruded by 0.26 mm,the left and right second molars were intruded by 0.37 mm and 0.36 mm,respectively.But the central incisors had no significant vertical movement.There was no significant difference in the buccally or palatally rotation of bilateral first and second molars.Conclusion:Invisible bracketless appliance is efficient for distalization of upper molar,but it may result in mild molar intrusion and anterior anchorage loss.

Objective To evaluate the use of transfer statements in inhouse transport of critical patients.Methods By means of continuous enrollment,123 critical patients were enrolled as a control group for conventional transport,and 111 such patients were enrolled as an observation group for transport using the transfer statement.Then the incidence of adverse events,transport during and nurse-nurse collaboration level of the two groups were compared.Results In the control group,its incidence of adverse events was 13.8%,the mean transport during was(19.5 ± 8.4)minutes,and the mean score for nurse-nurse collaboration level was ( 101.87 ± 7.13 ).In the observation group,its incidence of adverse events was 5.4%,the mean transport during was(13.5 ± 5.4)minutes,and the mean score for nurse-nurse collaboration level was(106.15 ± 8.86).Implementing the transfer statement has cut back the incidence of adverse events (P<0.05)and the transport duration significantly(t=3.833,P<0.01),while improving the level of nurse-nurse cooperation significantly(t= -4.261,P<0.05).Conclusions The transfer statement can increase the safety of patient transport,promote organization and coordination of nurses,and improve the efficiency of transport.

Objective To describe the prevalence and change of rationing of nursing care (RNC) in medical and surgical units of level 2 and level 3 general hospitals across Guangdong province. Methods RNC were measured by asking nurses about the completion status of 12 necessary nursing care activities, and the prevalence of RNC in 2014 was compared with the study results from the China Hospital Nursing Workforce Research(CNWR) in 2009 (exclusively using the data of Guangdong province) to describe the change of RNC. Results Six activities were rationed averagely in 2014, and the most frequent activities rationed wereComfort/talk with patients accounted for 69.8% (975/1 396) andEducating patients and familiesaccounted for 67.3%(940/1 396). According to the CNWR in 2009, the average number of nursing care activities rationed was 3 which was statistically lower than the number in 2014 (P < 0.01). Conclusions RNC is prevalent in level 2 and level 3 general hospitals across Guangdong province, especially psychosocial care to the patients; the prevalence of RNC has not decreased since 2009.
