Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.

Objective To explore the quantitative evaluation of integrity risk prevention and control in public hospitals,provide reference for improving the quality and efficiency of integrity risk prevention and control.Methods Self-designed"Inspection Standards for Integrity Risk Prevention and Control of Power Matters in Public Hospitals"was used to score and rate the power matters provided by each functional department/clinical department of West China Hospital of Sichuan University from three aspects:the clarity of power operation process,the accuracy of finding integrity risk points,the effectiveness of prevention and control measures.Results A total of 236 power matters of the hospital were inspected for integrity risk prevention and control,and according to the inspection criteria,57 items were rated as first grade,103 items were rated as second grade,and 76 items were rated as third grade,accounting for 24.15%,43.64%and 32.20%,respectively.The score for the special work of integrity risk prevention and control was 5.82±1.92 points,of which the process dimension score was 2.11±0.75 points,the risk points dimension score was 1.89±0.92 points,the prevention and control dimension score is 1.89± 0.79 points,which reflects the problems of unclear workflow,inaccurate finding of individual risk points,and unspecified prevention and control measures in some units.Conclusion Hospitals should focus on the concreteness,accuracy,salience and quantification in the long-term construction of integrity risk prevention and control from the aspects of thought,behavior,effectiveness and evaluation.

Objective To analyze the use of modified pericardial oblique sinus approach in surgical repair for total anomalous pulmonary venous connection in neonates. Methods Between May 2005 and December 2015, 67 consecutive neonates with supracardiac or infracardiac type total anomalous pulmonary venous connection who underwent surgical repair in our institute were included in this study. The patients are divided into three groups according to the different approaches including a sulcus approach group (6 patients), a superior approach group (14 patients), and a modified pericardial oblique sinus approach group (47 patients). There were 53 males and 14 females at median age of 12.5 (7.0, 20.5) d. Results The time of cardiopulmonary bypass [88 (80.0, 107.0) min vs. 135 (121.0, 157.0) min, P<0.05] and aortic cross clamping of the modified pericardial oblique sinus approach group was significantly shorter than that of the sulcus approach group [45 (39.0, 53.0) min vs. 80 (73.0, 85.0) min, P<0.05]. Perioperative mortality (2.1% vs. 28.6%, P<0.05) was significantly lower in the modified pericardial oblique sinus approach group than that in the superior approach group. The long-term mortality (4.3% vs. 60.0%, P<0.05) was significantly lower in the modified pericardial oblique sinus approach group than that in the sulcus approach group or the superior approach group . The rate of pulmonary venous stenosis was significantly lower in the modified pericardial oblique sinus approach group than that in the sulcus approach group (2.1% vs. 50.0%, P<0.05) or superior approach group (2.1% vs. 35.7%, P<0.05). Conclusions
In surgical correction of neonatal supracardiac and infracardiac total anomalous pulmonary venous, compared with the traditional surgical approach, the modified pericardial oblique sinus pathway can provide excellent surgical space and has a good surgical prognosis.

BACKGROUND: Studies have shown that bone marrow mesenchymal stem cells (BMSCs) can treat central nervous system diseases. BMSCs have the function of self-renewal and differentiation into a variety of neural cell types. BMSCs with self-renewal and multi-directional differentiation abilities can successfully differentiate into dopaminergic neurons after transplantation into an animal model. OBJECTIVE: To observe the effect of transplanted BMSCs on behavior and dopaminergic neurons in rats with manganese poisoning. METHODS: Rat models of manganese poisoning were constructed by intraperitoneal injection of MnCl2?4H2O into Sprague-Dawley rats. The model rats were then randomly divided into two groups, BMSCs and phosphate buffered solution (PBS) control group, and 5 μL of passage 3 human BMSCs suspension or equivalent PBS was transplanted into the right striatum of the manganese poisoning rats. One month after transplantation, the rats were subjected to behavioral assessment. The differentiation of BMSCs was observed by immunofluorescence. The contents of dopamine, brain-derived neurotrophic factor, glial cell-derived neurotrophic factor in the right striatum of rats were detected by ELISA. RESULTS AND CONCLUSION: The behavioral score of the BMSCs treated group was significantly lower than that of the PBS control group after transplantation (P < 0.05). Double-labeled positive cells for human-specific nuclear antigen/tyrosine hydroxylase (hNUC/TH) and human-specific nuclear antigen/glial cell-derived acidic protein (hNUC/GFAP) were observed in the BMSCs treated group after transplantation. Meanwhile, hNUC/TH and hNUC/GFAP double-labeled positive cells were undetected in the PBS control group after transplantation. The expression levels of dopamine, brain-derived neurotrophic factor, glial cell-derived neurotrophic factor in the BMSCs treated group were higher than those in the PBS control group. This suggests that BMSCs can improve the behavior of manganese poisoning rats and can differentiate into dopaminergic neurons and astrocytes.

Objective To investigate the effect of rapid rehabilitation nursing mode on postoperative complications in elderly patients with appendicitis. Methods Forty-eight elderly patients with appendicitis underwent surgery from July 2013 to June 2014 were set as the control group, and another fifty-three elderly patients from July 2014 to June 2015 as observation group. The patients in the control group were treated with routine care while the patients in the observation group with rapid rehabilitation nursing. Operative complications, gastrointestinal tumor recovery and postoperative hospitalization time were compared within one week after the operations between two groups. Result The rates of constipation, abdominal distention, chills and dysuria in the observation group were significantly lower than those of the control and the time of anal first exhaust, defecation and postoperative hospitalization in the observation group were significantly lower or shorter than those in the control group (all P<0.05). Conclusion The rapid rehabilitation nursing mode based on evidence can reduce surgery complications in elderly patients, promoter recovery and shorten hospitalization time.
