Objective To research the incidence and etiological factors of intraocular pressure(IOP)elevation in patients in early and late postop?erative stages after vitrectomy. Methods The clinical data of 235 cases(306 eyes)who underwent vitrectomy in our hospital were respectively ana?lyzed. IOP was measured before operation,in the early postoperative stage(within 2 weeks)and in the late postoperative stage(6 months after opera?tion or longer)by non?contact tonometer. Risk factors related with ocular hypertension happened in the early and late postoperative stages were statis?tically analyzed. Results The mean average IOP before operation was 15.3 ± 4.1 mmHg for the 306 eyes. Within the follow?up period of 6?20 months(mean,14.3 months),ocular hypertension occurred in 42 eyes[incidence,13.7%;mean,31.9 ± 6.0 mmHg]in the early postoperative stage and in 12 eyes[incidence,3.9%;mean,32.1 ± 5.7 mmHg]in the late postoperative stage. Logistic regression analysis revealed that lensecto?my,scleral buckling,cyclophotocoagulation,inert gas filling,silicone oil tamponade and diabetic retinopathy were the independent risk factors of oc?ular hypertension in early postoperative stage after vitrectomy,while lensectomy,scleral buckling,pan retinal photocoagulation,silicone oil tampon?ade,diabetic retinopathy and carotid artery stenosis were the independent risk factors of ocular hypertension in late postoperative stage after vitrecto?my. In addition,cyclophotocoagulation was a protective factor of IOP in the late postoperative stage. Conclusion The risk factors of ocular hyperten?sion after vitrectomy include the intraocular gapfiller,the mode of combined operation,disease type and carotid artery stenosis. IOP elevation that happens in the late postoperative stage is more harmful. Ocular hypertension in the late postoperative stage is not associated with that in the early stage.

Objectives To examine the association of the maternal high-fat (HF) diet with increased susceptibility to obe-sity and the development of metabolic diseases in their offspring, and observe difference in the effect of maternal vs. acquired high fat diet on metabolic state in their offspring. Methods A total of 15 SD female rats were divided into HF diet group (group H, n=9) and control diet group (group C, n=6). After fed on different diet for seven weeks, they were mated at the age of ten weeks and became pregnant. Their offspring were then divided to groups CH and HH fed HF diet and groups CC and HC fed control diet. At the age of 3 and 8 weeks, the metabolic markers and the liver pathohistological evidences of their offspring were obtained. Results The body weight, area under curve (AUC) of glucose tolerance, cholesterol and triglyceride were all higher in group H than those in group C (P<0.05) before pregnancy. The offspring of group H had a higher body weight than the offspring of group C at the age of 3 weeks (P=0.002), and no difference in AUC was found between two groups (P>0.05). At the age of 8 weeks, there was no difference in fasting glucose and insulin levels among the four offspring groups. The AUC and body weight were higher in group H than in group C (main effect of maternal diet, P=0.024, P=0.013). The AUCs were also higher in groups CH and HH than groups CC and HC respectively (main effect of acquired diet, P=0.041). The levels of total cholesterol, triglycerides and LDL at the age of 8 weeks were all higher in HH and CH groups than those in HC and CC groups (main effect of acquired diet, P=0.008, 0.007, 0.000, respectively). Their histological analysis at 8 weeks showed different degrees of fatty liver in HH, HC and CH groups, and normal liver in CC group. Conclusions Maternal HF diet may result in increased body weight, fatty liver and impaired glucose tolerance in their adult offspring, and thus increase the risk of developing metabolic diseases at their later age. .

Objective To evaluate the clinical efficacy of tissue-type plasminogen activator (tPA) treatment of children with plastic bronchitis.Methods The study retrospectively reviewed the clinical data of the children with plastic bronchitis who were admitted to Tianjin Children's Hospital from September 2013 to January 2015 and were treated with tissue-type plasminogen activator.This study analyzed the effect and safety of tPA treatment,including clinical and radiological changes and follow-ups.Results A lot of plastic secretions were safely removed from the bronchial tubes in all children and clinical manifestations including breathing,body temperature,transcutaneous oxygen saturation and image changes were significantly improved.Conclusions Bronchoscopy is an effective way to treat plastic bronchitis,but with the use of tPA a better clinical efficacy could be achieved.The method is safe and effective and should be applied early in the patients in order to prevent the occurrence of severe airway obstruction complications.

AIM:To investigate the activity of NF-?B in peripheral blood mononuclear cells (PBMCs) from patients with Graves disease (GD) and the significance in immunopathogenesis of GD.METHODS:Peripheral blood was collected from 22 untreated GD,20 treated GD with tapazole more than 1 year,and 25 healthy volunteers. PBMCs were isolated from the blood by histopaque-1077 density-gradient centrifugation. The activity of NF-?B in PBMCs was analyzed using gel electrophoretic mobility shift assay (EMSA). The contents of IL-1?,IL-6 and TNF-? were tested by radioimmunoassay.RESULTS:The activity of NF-?B in PBMCs of untreated GD group was increased remarkably,compared with that in the treated group and control (P

Objective To investigate the causes of re-fractures of non fracture vertebral body after percutaneous kyphoplasty (PKP).Methods 512 patients (618 vertebral bodies) treated with PKP because of osteoporosis VCFs were recruited from June 2010 to June 2014.There were 107 males (121 vertebral bodies) and 405 females (497 vertebral bodies) with the mean age of 70.38±7.59 years old (51 to 91 years).There were 406 single segment fracture and 106 double segment fractures cases,and the fracture segments were T4 to L5.The T value of the patients' bone mineral density (BMD) was from-1.0 to-5.2 SD.The clinic characteristics of all the patients including age,sex,body weight,body height,body mass index (BMI),BMD score of the spine,volume of bone cement,restoration rate of anterior/middle vertebral height,postoperative complications (pulmonary embolism,bone cement leakage,nerve injury),and treated vertebral level were analyzed.Results 52 patients (10.16％,52/512) experienced refractures of non fracture vertebral body after kyphoplasty,and 4 experienced re-fracture of the fracture vertebral body after kyphoplasty.The average age of the 52 patients was 71.88±7.74 years old,meanwhile,the ratio of female was 94.23％ (49/52),the mean T value of BMD-4.03±0.60 SD,the ratio of initial double segment fractures 51.92％ (27/52).In addition,among the 456 cases with no fracture,the average age was 70.21±7.56 years,the ratio of female was 77.19％ (352/456);the mean T value of BMD was-2.89±0.55 SD;the ratio of initial double segment fractures was 17.32％(79/456).The data above (age,T value of BMD and initial double segment fractures) were all with statistical significant differences.Whereas the BMI,volume of bone cement,intervertebral disc leakage and restoration rate of anterior/middle vertebral height had no significant difference between the two groups.Furthermore,in the re-fracture of non fracture vertebral body group,32 cases (61.54％,32/52) were nonadjacent fractures,and 20 (38.46％,20/52) were adjacent fractures.Conclusion Osteoporosis degree,female and initial double segment fractures were major risk factors in the development of re-fracture of non fracture vertebral body after PKP.

BACKGROUND: The treatment of multilevel cervical spondylotic myelopathy (MCSM) aims at sustaining the spinal cord compression and restoring the stability of the cervical vertebrae at most.OBJECTIVE: To analyze the clinical characters of anterior cervical discectomy with fusion and expansive open-door laminoplasty for MCSM.METHODS: Sixty-seven patients with MCSM were divided into two groups, and treated with anterior cervical discectomy with fusion (group A) or posterior cervical expansive open-door laminoplasty (group B). All the patients were followed up for 12 months, and the range of motion of cervical vertebrae, cervical curvature index were observed,as well as the Visual Analogue Scale and Japanese Orthopaedic Association scores were condueted. Moreover, the operation time, blood loss and adverse reactions were recorded.RESULTS AND CONCLUSION: (1) The loss of range of motion of the cervical vertebrae in the group B was significantly less than that in the group A (P < 0.05). (2) The cervical curvature index in the group A was significantly improved (P < 0.05), but the index had no significant change in the group B. (3) The axial systems were significantly improved in both groups, especially in the group A (P < 0.05). (4) The neurological function was significantly improved in both groups (P < 0.05), which showed no significant difference between two groups (P > 0.05). (5) The intraoperative blood loss in the group B was significantly more than that in the group A (P < 0.05). (6) The incidence of hoarseness and dysphagia in the group A was 19％. The incidence of wound infection, cerebrospinal fluid leakage and C5 nerve root palsy in the group B was 9％. (7) These results suggest that during choosing an appropriate method for MCSM,surgeons' skills and patients' situation should be considered.

The event-related potential (ERP) is considered as one of the most effective methods to study and analyze objectively human mental activity based on nerve electrophysiology. At present, ERP is not only used in the study of lie detection, but also in the clinical medicine for the cognitive assessment on patients with cerebrovascular disease, dementia or traumatic brain injury and auxiliary diagnosis of mental illness. With the further development of ERP detection technology, it would have a wider application prospect in the field of forensic medicine.

BACKGROUND: As is well known that hematopoietic stem and progenitor cells (HSPCs) contain in bone marrow, peripheral blood, and cord blood. Recent studies found that human placenta tissue (PT) also exists in HSPCs. But so far the property and differentiation capacity of human PT-HSPCs is not yet known. Furthermore the composition of lymphocyte subpopulations and immunogenicity regarded to human PT-HSPCs are also unclear.OBJECTIVE: To verify whether there are more HSPCs in human PT than those in human umbilical cord blood (UCB), to investigate their capacities of proliferation and differentiation, and to analyze the phenotypes of lymphocyte subpopulations in human PT.DESIGN, TIME AND SETTING: Open eXperiments were performed at the Key Laboratory of Cell Engineering of Guizhou Provinee from January 2004 to December 2006.SETTING: Key Laboratory of Cell Engineering of Guizhou Province, the Affiliated Hospital of Zunyi Medical College.MATERIALS: Twelve human placenta and UCB samples through cesarean delivery were collected aseptically with the informed consents of parturients derived from Maternity Department of the Affiliated Hospital of Zunyi Medical College. The main reagents were detailed as follows: lymphocyte subpopulations analysis reagents Simultest IMK-lymphocyte Kit, CD34 absolute counting reagents Kit (Becton Dickinson); CD34 Multisort Kit, FITC conjugated CD38 monoclonal antibody, anti-FITC microbeads and MS/LS mini MACS segregating, columns (Miltenyi Biotec).METHODS: UCB samples were 1:1 diluted with RPMI-1640 containing 0.1 volume fraction of fetal bovine serum and the mononuclear cells (MNCs) were isolated on Ficoll-Histopaque by centrifugation for 30 minutes. The MNCs at the interface were collected and washed with PBS. Single cells suspension liquid of human PT was prepared by mechanical method combined with 0.25g/L collagenase digestion. After that, the placenta samples underwent the same protocol as used in UCB to isolate MNCs. The percentage of CD34+CD38-, CD34+CD38+ HSPCs and the phenotype of lymphocyte subpopulations derived from human PT-MNCs were analyzed by flow cytometry (FCM). CD34+CD38-, CD34+CD38- cell subsets isolated by magnetic-activated cell sorting (MACS) from human PT were used to carry out colony-forming culture including granulocyte/macrophage colony-forming unit (CFU-GM), burst forming unit-erythroid (BFU-E) and mixed colony-forming unit (CFU-Mix) in order to assess their capacities of hematopoietic progenitor cells' proliferation and differentiation. In parallel, UCB samples underwent the same protocols for comparison.MAIN 0UTCOME MEASURES: Percent compositions of CD34+ HSPCs, hematopoietic progenitors' lineage colony-forming capacities of CD34+ HSPCs, phenotypes and compositions of lymphocyte subpopulations both in PT and UCB.RESULTS: The percentage of CD34+ cells contained in human PT was 8.8 times higher than that of in UCB (P<0.01). The total number of lymphocytes, T cells (CD3+CD2+), B cells (CD19+), Th (CD3+CD4+) and Th/Ts ratio were apparently lower in human placenta, while the number of CD8+CD28- T suppressor cells were higher compared to UCB samples (P<0.01). Among PT, CFU-GM, BFU-E and CFU-Mix frequencies of CD34+CD38- cells subset were much higher than that of CD34+CD38- (P<0.01). Within the same phenotype of cell subsets, however, the number of each colony-forming unit was similar between PT and UCB (P 0.05).CONCLUSION: Human PT is richer in CD34+CD38-, CD34+CD38+ HSPCs and both of them have the abilities of proliferating and differentiating into CFU-GM, BFU-E and CFU-Mix. Considering that human PT have a lower lymphocyte subpopulations and higher Ts cells, human PT might be a alternative and suitable source of HSPCs for clinical transplantation.
