This study was aimed to observe effects of herbal pair of semen Ziziphi Spinosae (SZS) and A lbizia Julib-rissin flower (AJF) on cognitive function and serum BDNF among depression patients. A total of 60 depression pa-tients were enrolled and randomly divided into two groups. In the SZS-AJF group, 30 patients were administered with SZS-AJF decoction. In the control group, 30 patients were administered with venlafaxine hydrochloride sus-tained-release tablets. Hamilton Depression Rating Scale (HAMD), Wisconsin Card Sorting Test (WCST), and the serum-brain derived neurotrophic factor (BDNF) were detected before treatment and after six weeks of treatment. The results showed that there were no significant differences on the HAMD score, WCST (Response Administered (Ra), Categories Completed (Cc), Correct Responses (Cr), Perseverative Errors (Pe), Non-perseverative Errors (Npe)), serum BDNF before and after treatment between two groups. Compared with pretreatment, HAMD score, Ra, Cc, Cr, serum BDNF were increased after treatment in both groups. The Pe and Npe were decreased after treatment. There was sta-tistical significance between pretreatment and posttreatment (P< 0.05, or P< 0.01). It was concluded that the herbal pair of SZS-AJF has anti-depressant effect. It can improve cognitive function of depression patients. The anti-de-pressant mechanism of herbal pair of SZS-AJF may be related to the increasing of serum BDNF level.

Objective To compare differences of gut microbiome between patients with severe acne vulgaris and healthy individuals by using high-throughput sequencing technology.Methods Stool samples were collected from 10 outpatients with severe acne vulgaris and 10 age-and sex-matched healthy controls.Then,the bacterial DNA was extracted and subjected to 16S rRNA sequencing for the identification of microbial species,and the differences of gut microbiome were compared between the patients and controls.Results There were no significant differences in the diversity of intestinal microflora,but only the relative abundance of a few bacteria differed significantly between the two groups.Gut microbiome in the two groups mainly consisted of Bacteroidetes,Firmicutes,Proteobacteria and Actinobacteria.There were no significant differences in the relative abundance of bacteria at the phylum and genus levels between the two groups.However,the relative abundance of Blautia producta and Coprococcus eutactus at the species level differed remarkably between the two groups.Conclusion No significant differences in the bacterial diversity indices are found,but some bacterial species significantly differ between the patients with severe acne vulgaris and healthy controls.

Objective To evaluate the effect of extracorporeal membranous oxygenation (ECMO) on the small bowel preservation in a porcine model of controlled donors after cardiac death (CDCD).Method The domestic crossbred donor pigs were anesthetized and ventilated with 100％ oxyger.An intravenous cannula was placed through iliac arteries and jugular vein,and connected to ECMO system.The ECMO was performed to infuse abdominal organs when cardiac death was declared.Pathology,electron microscope,energy metabolism and cell apoptosis level of intestinal mucosa were evaluated before operation,in cardiac death and at the end of extracorporeal support,respectively.Result The normothermic extracorporeal support could quickly restore graft blood supply and oxygenation.One-h extracorporeal support could improve the energy status in intestine of donation after cardiac death (DCD).The histologic damage and apoptosis of 1-h extracorporeal support had no significant difference with those before operation and in cardiac death (P＞0.05).With the extension of extracorporeal support,the intestinal mucosa damage degree was gradually increased,and the content of adenosine triphosphate in intestinal mucosa reduced gradually.Conclusion The normothermic extracorporeal support for 1 h in DCD is beneficial for improving the viability of small bowel.However,the integrity of intestinal mucosa is destroyed gradually as extracorporeal supporting time over,which may be initiated by the activation of intestinal epithelial apoptosis.

Objective To investigat the changes of hemodynamics and arterial blood gas during the establishment of ECMO model and provide an ideal platform for the study of the mechanism of DCD protection using ECMO, a porcine model of controlled donors of cardiac death (CDCD) with extracorporeal support was established in the paper. Methods Eight domestic crossbred pigs were anes-thetized, atracurium (1mg/kg) and heparin (150~200 U/kg) was administered and the ventilator was discontinued while the animal was under deep anesthesia to kill the animal.Meanwhile, blood was drained from the left jugular vein catheter into the ECMO circuit and re-turned into the left femoral artery to establish the porcine model of CDCD with extracorporeal support . The average blood press and arterial blood gas were ministered at normal, cardiac arrest and ECMO supporting 1 h, 3 h and 5 h. Results The model of CDCD with extra-corporeal support was established successfully.Two animals restored the beating of the heart and the high doses of potassium chloride were given untill cardiac arrest during extracorporeal support.Blood gases throughout the apneic time showed a severe hypoxemia and acidosis, pH and PaO2 reduced to 7.09 ±0.24 and 5.3 ±0.93mmHg respective-ly, which can be improved during extracorporeal support.MAP and PaO2 were maintained over 300mmHg and 65mmHg respectively. Conclusion A new porcine model of controlled donors of cardiacdeath with extracorporeal support has been successfully established and showed to be feasible for related pathophysiological research work.

BACKGROUND:Mesenchymal stem celltransplantation promoted skin repair in trauma via various regulatory mechanisms and inhibited scar formation. At present, many scholars believed that bioactive factors secreted by mesenchymal stem cells played an important role.
OBJECTIVE:To investigate the effects of bone marrow mesenchymal stem cellconditioned medium on the proliferation and col agen synthesis of hypertrophic scar fibroblasts.
METHODS:Human bone marrow mesenchymal stem cells and hypertrophic scar fibroblasts were isolated and cultured, and bone marrow mesenchymal stem cellconditioned medium was prepared. Hypertrophic scar fibroblasts were cultured in vitro with 12, 24, and 48 hour-col ected conditioned medium for 24 hours, which was compared with blank control group. The proliferation of cells was determined by CCK-8. Type I and type III col agen expression in hypertrophic scar fibroblasts was detected using real-time PCR.
RESULTS AND CONCLUSION:Compared with the blank control group, 24 and 48 hour-col ected conditioned medium significantly inhibited the proliferation of hypertrophic scar fibroblasts (P<0.01), and also suppressed col agen synthesis of hypertrophic scar fibroblasts (P<0.01). Results suggested that bone marrow mesenchymal stem cellconditioned medium inhibited the proliferation and col agen synthesis of hypertrophic scar fibroblasts by secreting anti-fibrotic bioactive factors, which may provide new theoretical supports for celltherapy to reduce cutaneous scarring.
