BACKGROUND:The key of stem cells for treating nervous tissue injury is the transplantation of stem coils that have regeneration capacity.The structure and function of central nervous system were re-established by multiple action mechanisms.OBJECTIVE:To explore the effects and mechanisms of bone marrow mesenchymal stem cells(BMSCs)locally transplanted into rats with spinal cord injury on neurological recovery.METHODS:BMSCs were separated with density gradient centrifugation and cell attachment.10 mg/L BrdU was used for labeling before cell transplantation.Adult female Wistar rats were used to establish spinal cord injury models using an aneurysm clip,and they were then randomly divided into control group,saline group and transplantation group.In the transplantation group,BMSCs were transplanted into the damaged spinal cord by stereotaxis at day 7 following damage.In the saline group,an equal volume of saline was utilized.In the control group,the rats were left intact.Basso,Beattie and Bresnahan(BBB)locomotor rating scale was used before and at 7,14,30,60 and 90 days following damage.Rats were sacrificed at day 90.BrdU-positive cells,Brdu+neuron specific enolase,Brdu+glial fibrillary acidic protein(GFAP),Brdu+basic fibroblast growth factor(bFGF),and Brdu+brain-derived nerve growth factor(BDNF)immunohistochemistry double-staining cells and simple staining positive calls were observed.RESULTS AND CONCLUSION:The recovery of BBB function score was better in the transplantation group than in the control group(P＜0.05).The recovery speed of BBB function score was slower in the saline group than in the control group at 30 days following damage(P＜0.05).No significant difference was determined at day 90 compared with the control group(P＞0.05).BrdU-positive cells and double-staining cells of immunohistochemistry could be found at the center of damage site and 1 cm from caudal end to damaged site in rats of the transplantation group.The number of NSE,GFAP,bFGF and BDNF simple staining cells was significantly greater in the transplantation group than in the control and saline groups(P＜0.05).Results indicated that BMSC transplantation can improve the recovery of nervous function of rats with spinal cord injury.Its mechanism may be correlated with the differentiation of transplanted cells into neuron-like and glial cell-like cells,secretion or promoting secretion of neurotrophic factors in host.

Objective: To explore the antagonistic effect of quercetin on fine particulate matter (PM2.5)-induced embryonic developmental toxicity in vitro.Methods: PM2.5 was collected on glass fiber filters by PM2.5 samplers during the heating period of Dec.2015 to Mar.2016 in an area of Haidian District, Beijing City.The sampled filters were cut into 1 cm×3 cm pieces followed by sonication.The PM2.5 suspension was filtered into a 10 cm glass dish through 8 layers of sterile carbasus and stored at-80 ℃ until freeze drying.Frozen PM2.5 suspension was dried by vacuum freeze-drying.In vitro post-implantation whole embryo culture was used in this study.Pregnant rats with 9.5 gestation days (GD) were killed by cervical dislocation and the uteri were removed into sterile Hank's solution.The embryos with intact yolk sacs and ecto placental cones were induced by PM2.5, and then subjected to intervention of quercetin at the doses of 0.1 μmol/L, 0.5 μmol/L, 1.0 μmol/L and 5.0 μmol/L, respectively.At the end of the 48 h culture period, the cultures were terminated, and all embryos were removed from the culture bottles and placed in prewarmed Hank's solution for evaluation.Morphological evaluation of the embryos was conducted under a stereomicroscope using the morphologic scoring system by Brown and Fabro.The mitochondrial reactive oxygen species (ROS) level was detected by FACSCalibur flow cyto-metry using MitoSOXTM Red staining.Results: An obvious antagonistic effect was achieved through querce-tin at the dose of 1.0 μmol/L, which could result in an increase of visceral yolk sac (VYS) diameter, crown-rump length and head length, somite number, and the differentiation of visceral yolk sac vascular vessels.The scores of allantois, flexion, heart, hind brain, midbrain, forebrain, auditory system, visual system, olfactory system, branchialarch, maxillary process, forelimb bud and hindlimb bud also revealed a significant increase and the relative mitochondrial ROS level of embryonic cells was significantly decreased when compared with PM2.5 group.Although quercetin at the doses of 0.1 μmol/L, 0.5 μmol/L, 5.0 μmol/L also exhibited protective effects against PM2.5-induced embryonic developmental toxicity, the protective effect was weaker when compared with the dose of 1.0 μmol/L.Conclusion: Quercetin at proper dose may be of great benefit for the development of embryos exposed to PM2.5 in the uterus of the rats.Quercetin provides an effective strategy for the prevention of PM2.5-induced embryonic developmental toxicity.Clearance of mitochondrial ROS may be one of its mechanisms.

Objective:To discuss the risk factors in lung cancer patients with chemotherapy-induced severe neutropenia to provide reference for clinical drug use. Methods:A retrospective analysis was performed for the patients with lung cancer,and the risk factors of severe neutropenia were statistically analyzed and found out. Results:The results of single factor experiments showed that the incidence of severe neutropenia was related with radiotherapy history,cycles of chemotherapy and the use time of granulocyte colony factor. Based on a binary logistic regression analysis,the history of radiotherapy and the use of granulocyte colony factor were the significant risk factors of severe neutropenia in the lung cancer patients. Conclusion:For the patients with radiotherapy history,it is better to choose chemotherapy drugs with lower toxicity,decrease drug dosage or preventively use granulocyte colony factor. The rational use of rhG-CSF can alleviate chemotherapy-induced severe neutropenia.

Objective To describe the circadian profiles of interdialytic blood pressure in maintenance hemodialysis patients and to investigate its related factors. Methods Ambulatory blood pressure monitoring (ABPM)was conducted in forty-four patients on regular hemodialysis during interdialytic days.Three groups were identified with their ambulatory blood pressure:non-hypertension group,controlled hypertension group and uncontrolled hypeaension group.Hemoglobin,creatinine,Kt/V,serum total calcium,serum phosphate,immunoreactive parathyroid hormone(iPTH),interdialytic weight gain and Morisky self-report scale etc.were assessed. Results (1)No significant difference was found in ABPM index ranged from decline in nocturnal systolic and diastolic blood pressure,AASI to dipper percentage in three groups.Nevertheless,24-h average pulse pressure in uncontrolled hypertension group was higher than the other groups[(80.06+13.41)vs(53.00±7.73),(57.85±21.97)mm Hg,all P＜0.01].(2)All the three groups showed the blood pressure profile of double-peak and trough.In the uncontrolled hypertension group,however,the nocturnal blood pressure decrease was not notable.(3)Nocturnal systolic blood pressure decline Was negatively correlated to iPTH(r=-0.039,P＜0.05).(4)In ten dippers out of all 44 patients,AASI was negatively correlated with nocturnal diastolic blood pressure decline (r=-0.748,P＜0.05). Conclusion Nocturnal blood pressure decline is correlated to iPTH and arterial selerosis.

Gut microbiota provide enzymes and additional biochemical metabolic pathways for the host, which together with the host genome and the external environment, influence the body function. The composition of gut microbiota in infant is closely related to health in later life. However, it is influenced by many factors, including delivery mode, feeding pattern, prenatal diet, pregnancy psychology and antepartum antibiotic treatment. Vaginal delivery and breastfeeding is beneficial for shaping gut microbiota, while cesarean section and formula feeding would reduce the amount of gut dominant bacteria. In addition, inappropriate diet during pregnancy, prenatal stress and antepartum antibiotic treatment alters bacterial colonization of the gut in infant.

Objective:To investigate the efficacy and side effects of amnion stent implanted in lacrimal duct for the lacrimal duct obstruction diseases (LDOD).Methods:A randomized controlled clinical trial was adopted.Seventy-two eyes of 72 patients with LDOD treated in Jiangxi Provincial People's Hospital from June 2014 to January 2015 was randomized into the experiment group and the control group with amnion stent or silicone tube retrogradely implanted according to grouping in accordance with block randomization with 36 eyes in each group.All patients were performed irrigation of lacrimal passage at 3 and 6 months postoperatively to compare the patency rate of lacrimal duct and side effects between the two groups.This study followed the Declaration of Helsinki.Written informed consent was obtained from each subject prior to entering the study cohort.The study protocol was approved by the Ethics Committee of Jiangxi Provincial People's Hospital (No.2014-002).Results:The patency rate of lacrimal duct was 91.7%(33/36) and 80.6%(29/36) at 3 months postoperatively in the experimental and control group, respectively.Although the difference was obvious, there was no statistical significance ( P=0.307). The patency rate of lacrimal duct was 88.9%(32/36) and 75.0%(27/36) at 6 months postoperatively in the experimental and control groups, respectively.Similarly, the difference was obvious, however there was no statistical significance ( P=0.220). At 3 months and 6 months postoperatively, the incidence of epiphora in the experimental group was lower than that in the control group, it was significantly different ( Z=2.729, P=0.006), and there was no significant difference at 6 months postoperatively ( Z=1.921, P=0.055). At 6 months follow-up period, the attack rate of side effects, such as dacryon congestion and exudation, was 2.8%(1/36) and 13.9%(5/36) in the experiment and control groups, respectively, however, the difference was no statistical significance ( P=0.199). Conclusions:The implantation of amnion stent in lacrimal duct for LDOD is effective, and the patency rate of lacrimal duct is not lower than that of the implantation of silicone tube in the lacrimal duct.

Organ transplantation is an effective treatment for end-stage organ failure. However, organ shortage has always been a common problem faced by countries around the world. The recognition and active participation of intensive care unit (ICU) medical staff in organ donation contributes to promoting the development of organ donation, thereby alleviating the shortage of donor organ. In this article, the key strategies of ICU donor management to promote organ donation and the key strategies of ICU medical staff management to promote organ donation were summarized, aiming to provide reference for organ donation practitioners (especially ICU medical staff) and jointly facilitate the professional development of organ donation.
