BACKGROUND:Human umbilical cord mesenchymal stem cel s belong to a special class of stem cel s with a limited number, which are difficult to isolate and purify. Importantly, there is a lack of clinical understanding of biological characteristics of human umbilical cord mesenchymal stem cel s. OBJECTIVE:To study the bioactive properties and cardiomyocyte-like differentiation of human umbilical cord mesenchymal stem cel s. METHODS:Under a sterile col ection, umbilical cord blood of newborn from cesarean section was col ected to isolate human mesenchymal stem cel s by digestion using col agenase II. Immunohistochemical staining was used to detect cel surface markers and observe morphological characteristics, and MTT assay used to detect cel proliferation and draw cel growth curve. Cel s grown to 70%-80%confluence were treated with 10μmol/L 5-azacytidine for 24 hours. RESULTS AND CONCLUSION:One week after adherent tissue culture, human umbilical cord mesenchymal stem cel s were seen, and then the cel s cultured in culture medium showed colony growth. Within 24 hours of cel seeding, cel s at passages 3 and 10 were at latency period and then grew logarithmical y with a doubling time of 30 hours. Immunocytochemical staining showed that passage 3 cel s at over 90%confluence expressed CD44 and CD29, rather than CD28 and CD31.Three weeks after induced culture, the cel s with the absence of processes grew irregularly;after 4 weeks, the cel s were round in shape and expressed cardiac-specific immune markers. Taken together, isolated human umbilical cord mesenchymal stem cel s with strong proliferative ability have the basic biological characteristics of mesenchymal stem cel s, which are capable of differentiating into cardiomyocyte-like cel s induced by 5-azacytidine.

B-D experiment is the main way to determine the safety of pulsation vacuum sterilization machine, but the positive result by B-D experiment doesn't always result from the error of the machine for too many influencing factors. In this paper, Analysis and verification of positive B-D experiment result are performed, and thus the sterilization machine can be used properly.

Objective To investigate the correlation between hemorrhagic transformation (HT) and each parameter of blood pressure variability (BPV) in patients with massive cerebral infarction caused by cardioembolic middle cerebral artery occlusion. Methods The patients with massive cerebral infarction caused by unilateral cardioembolic middle cerebral artery occlusion admitted to hospital within 24 h after onset were selected. For patients without revealing HT with head MRI on admission were analyzed retrospectively. According to the results of MRI rescan within 7 days after onset, they were divided into either a HT group or a non-HT group. Al specific parameters of blood pressure were compared and analyzed between the 2 groups, specificaly including initial value (initial), mean value ( mean), maximum value (max), minimum value (min), maximum-minimum difference (max-min), standard deviation (sd), successive variation (sv), and maximum value of sv (svmax) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results A total of 146 patients were enroled in the analysis, and 77 (52. 7% ) had HT within 7 d after onset. Al the blood pressure parameters were grouped by quartiles. Multivariate logistic regression analysis showed that after adjusting for age, admission time, baseline National Institutes of Health Stroke Scale score, congestive heart failure, antiplatelet therapy, initial blood glucose, prothrombin time, and international normalized ratio of the patients, SBPmin , SBPmax-min , SBPsv , SBPsvmax , DBPinitial, DBPsd , DBPmax , DBPmax-min , DBPsv , and DBPsvmax had significant independent association with and HT (likelihood ratio test of trend, al P < 0. 05). Conclusions Higher BP level and variability may increase the risk of HT in patients with massive cerebral infarction after cardioembolic middle cerebral artery occlusion. A smooth and slow antihypertensive treatment may need for these patients.

The research on clinical efficacy evaluation of traditional Chinese medicine (TCM) is a hot and difficult issue in the field of TCM. However, the overall level of current related research also needs to be improved. There are still a lot of academic controversies in the field of TCM clinical efficacy evaluation. The author believed that before conducting research, it is necessary to sort out core issues of TCM clinical efficacy evaluation, which in-clude the concept of TCM clinical efficacy and its evaluation. In recent years, Chinese scholars have conducted a series of studies on these issues and have some achievements. To think and answer these questions will play an important role for the ultimate resolution of problem of TCM clinical efficacy evaluation.

Through analyzing the current situation and coverage controversy of Chinese clinical trial insurance,this paper stated that the attending insurance rate in domestic clinical trials was entirely low.The sponsors,clinical trial institutions,investigators and insurance companies paid attention of different levels to clinical trial insurance.Therefore,the risk awareness of drug/medical device clinical trials should be enhanced.It is necessary to give impetus to clinical trial insurance system,during which all parties need to make a joint effort including government departments,ethics committees,sponsors,clinical trial institutions,investigators and insurance companies.

Objective To investigate the correlation between early blood pressure variability and early neurological deterioration (END) in patients with acute ischemic stroke.Methods Inpatients with acute ischemic stroke were collected prospectively.The blood pressure values of the enrolled patients were recorded continuously for 72 h after admission.The mean value (mean),maximum value (max),differences betw een the maximum and minimum (max-min),standard deviation (SD),and coefficient of variation (CV) for the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were calculated.END was as an increase of at least 2 in the highest score of the National Institute of Health Stroke Scale (NIHSS) compared to the baseline.Multivariate logistic regression analysis was used to identify the independent correlation between the different blood pressure variability parameters and END following acute ischemic stroke after adjusting the confounding factors.Results A total of 128 patients with acute ischemic stroke were enrolled,including 53 females and 75 males,and their mean age was 63.30 ± 11.82 years.After standard treatment,35 patients (27.34％) developed END within 72 h after admission.There were significant differences in age,sex,diabetes mellitus,baseline NIHSS,C-reactive protein and SBPmax,SBP in,SBPSD,SBPCv,DBPmax,DBP max-min,DBPsD,and DBPCv between END group and non-END group (all P ＜0.05).Multivariate logisticregression analysis showed that SBPmax-min(odds ratio [OR] 1.040,95％ confidence interval [CI] 1.014-1.067,SBPsD(OR 1.191,95％ CI 1.052-1.347),SBPCv(OR 1.317,95％ CI 1.100-1.578),DBP max-min(OR 1.076,95％ CI 1.018-1.138),DBPsD(OR 1.508,95％ CI 1.128-2.016),and DBPCv(OR 1.338,95％ CI 1.093-1.638) in blood pressure variability indices were the independent risk factors for END in patients with acute ischemic stroke.Conclusion Blood pressure variability is significantly associated with END within 72 h after admission in patients with acute ischemic stroke.

OBJECTIVETo study and summarize the etiology of children patients with chronic kidney disease (CKD) stage 2 to 5 seen in Children's Hospital of Fudan University from Jan. 2004 to Dec. 2013.

METHODBy complying with the NKF-K/DOQI guidelines, we collected data of 264 cases of children patients with CKD stage 2-5 from Jan. 2004 to Dec. 2013 in the medical record system of Children's Hospital of Fudan University. And we retrospectively analyzed their age and CKD stage at first diagnosis, primary diseases, complications, etc.

RESULTIn the collected 264 cases, 52 cases (19.7%) were diagnosed at stage 2, 67 (25.4%) at stage 3, 52 (19.7%) at stage 4 and 93 (35.2%) at stage 5. For disease causes, 116 cases (43.9%) had congenital anomalies of the kidney and urinary tract (CAKUT), 61 cases (23.1%) had glomerular disease, 15 (5.7%) had hereditary kidney disease, 14 (5.3%) had other diseases and in 58 cases (22.0%) the causes of disease were unknown. In the group with age between 0 and 3.0 and 3.1 and 6.0 years, 57.1% (24 cases) and 60.0% (30 cases) had primary disease with CAKUT. In the group with age older than 10 years, 49.2% (30 cases) had primary disease with glomerular disease and 32.0% (32 cases) with unknown causes.

CONCLUSIONThe major cause of CKD stage 2-5 in children in our hospital during the last ten years was CAKUT (43.9%), followed by glomerular disease (23.1%). The primary diseases of CKD were significantly different between the 2 age groups. CAKUT was more common in infants and preschool children while for adolescents, glomerular disease was the major cause.
