BACKGROUND: Human umbilical cord blood stem cells have been widely used in the study of spinal cord injury, but in vitro differentiation of human umbilical cord blood stem cells (hUCBSCs) has been limited by various factors. Mongalian medicine axillary choerospondias fruit extract has protective effects on neural cells, but the action mechanisms are unclear. OBJECTIVE: To observe promoting effects of 3 kinds of Mongalian medicine axillary choerospondias fruit extracts on in vitro differentiation of hUCBSCs. METHODS: Fresh umbilical cord blood was obtained from healthy puerperants to prepare hUCBSC suspension. The purified hUCBSCs were incubated in 40 petri dishes. The Mongalian medicine axillary choerospondias fruit extracts were divided into: sample 1 group: ethanol extraction, ethyl acetate extraction, crude drug mass concentration was 8.25 g/mL; sample 2 group: ethanol extraction, NKA resin isolation, 10% ethanol eluting concentration, crude drug mass concentration was 1.72 g/mL; sample 3 group: ethanol extraction, NKA resin isolation, 70% ethanol eluting concentration, crude drug mass concentration was 2.41 g/mL; control group: incubation of 80% DMEM containing 20% calf serum. Effects of various mass concentrations of Mongalian medicine axillary choerospondias fruit extract on hUCBSCs proliferation were observed. Proportion in S phase was measured using flow cytometry at 24 and 72 hours. RESULTS AND CONCLUSION: The proliferation of hUCBSCs was not significant in the sample 3 group. At day 10, the proliferation was significantly greater in the sample 1 and 2 groups compared with the sample 3 and control groups (P < 0.01). The number of hUCBSCs was significantly increased at 24 and 72 hours in S phase in the sample 1 and 2 groups. Mongalian medicine axillary choerospondias fruit extract (crude drug mass concentration 8.25, 1.72 g/mL) could promote in vitro proliferation of hUCBSCs.

Objective To analyze the level of satisfaction and its influencing factors in emergency patients, and to improve the satisfaction level of emergency patients. Methods The patients who visited the emergency department with the triage number ended with 1 from August 1 to August 15, 2015 in Second Affiliated Hospital of Zhejiang University School of Medicine were selected by the method of convenience and equidistant sampling, to take the Press Ganey′s Patient Satisfaction Questionnaires which were collected and analyzed at the end of the patient's emergency treatment. Results A total of 200 cases were investigated. Patient experience overall satisfaction was (91.64 ± 8.74) points. There were no significant differences in satisfaction between the gender, age, place of residence, the investigator, the clinic department, the time to wait, whether the first visit and the previous stay in hospital (P>0.05). The correlation between the satisfaction score and the patient's education, prognosis was less (r=-0.251,0.262, P =0.009,0.018) , but more higher correlated with the service attitude of ancillary hospital staff, nursing staff in the provision of nursing instructions, nursing staff can protect the privacy, the waiting time of the triage and the doctor′s explanation of the treatment of the disease (r=0.79-0.84, P<0.05). Conclusions The service attitude of the ancillary hospital staff, nursing staff in the provision of care instructions and privacy protection, and the waiting time of the triage and the doctor′s explanation of the treatment are the most important factors influencing the patients′ satisfaction in emergency department which also will be the key content for us to improve the patients′experience and satisfaction inemergency patients.

OBJECTIVETo quantitatively evaluate the metabolic changes of benign prostatic hyperplasia (BPH) and prostate cancer in the transitional zone using magnetic resonance spectroscopic imaging (MRSI), and to analyze the characteristics and differences of the spectra in this zonal area.

METHODSEighteen patients with prostate cancer in the transitional zone underwent magnetic resonance imaging (MRI)/MRSI examinations. The (Choline + Creatine)/Citrate (CC/Ci) ratio and the Choline/Creatine (Cho/Cr) ratio were evaluated in each voxel with cancer or BPH confirmed by pathological results. Discriminant analysis was used to determine the power of the two ratios in differentiation between cancer and BPH.

RESULTSThe CC/Ci ratio and Cho/Cr ratio for cancer voxels were significantly higher than those in the voxels with BPH in the transitional zone (CC/Ci: 2.36 +/- 1.31 vs. 0.85 +/- 0.29, P < 0.01; Cho/Cr: 4.14 +/- 1.79 vs. 1.26 +/- 0.45, P < 0.01). As for the discriminant function with the CC/Ci ratio and the Cho/Cr ratio, the specificity, sensitivity, and accuracy were 98.6%, 85.7%, 92.9% respectively for the differentiation between cancer and BPH.

CONCLUSIONSThe prostate cancer is characterized by higher CC/Ci ratio and Cho/Cr ratio compared to BPH in the transitional zone. Both CC/Ci ratio and Cho/Cr ratio have high specificity, sensitivity, and accuracy in their discriminative power between cancer and BPH in this zonal area.

OBJECTIVETo explore the ability of interictal diffusion-weighted imaging (DWI) to localize the temporal lobe of seizure origin and to predict postoperative seizure control in patients with temporal lobe epilepsy (TLE).

METHODSTwenty-seven patients with intractable TLE considered for surgery and 19 healthy volunteers were studied with conventional magnetic resonance imaging (MRI) and DWI. Apparent diffusion coefficients (ADCs) of bilateral hippocampi in both TLE patients and control subjects were obtained. Lateralization to either temporal lobe with hippocampal ADC was based on the threshold values derived from +/- SD of right/left ratios in normal subjects. And the postoperative pathology was reviewed.

RESULTSHippocampal ADCs were higher on the side of surgery compared with those on the contralateral side as well as the ipsilateral side in control subjects [resected side (109.8 +/- 7.3) x 10(-5) cm2/s, contralateral side (91.7 +/- 4.7) x 10(-5) cm2/s, control subjects (81.6 +/- 5.2) x 10(-5) cm2/s, all P < 0.01]. Right/left hippocampal ADC ratio and conventional MRI lateralized to the operated temporal lobe in 21 of 27 (77.8%) and in 18 of 27 (66.7%) patients. Lateralization to the surgical side was not associated with postoperative seizure control with right/left hippocampal ADC ratio (P > 0.05).

CONCLUSIONSConventional MRI is a sensitive method to detect hippocampal sclerosis. Accuracy of the right/left hippocampal ADC ratio for lateralizing to the side of surgery is very high, but it isn't a better predictor of surgical outcome.
