Although there are many drugs for the treatment'of cerebral infarction, no satisfactory efficacy has achieved. Mesenehymal stromal cells (MSCs) have multilineage differentiation potential and self-renewing capability, and can differentiate into neurons. The transplanted MSCs can improve neurological deficit after cerebral infarction, promote the recovery of neurological function, and thereby reduce the disability of cerebral infarction through the mechanisms such as releasing nutritional factors and growth nutritional factors, promoting angiogenesis. The use of MSCs for cell transplantation is likely to be an ideal means in the treatment of cerebral infarction.

Objective To investigate the influence of neoadjuvant chemotherapy on the occurrence of postoperative nausea and vomiting ( PONV) after radical mastectomy. Methods A total of 286 breast cancer patients, aged 18-60 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective modified radical mastectomy under general anesthesia in our hospital, were divided into either non?chemotherapy group ( n=106 ) or neoadjuvent chemotherapy group ( n=180 ) . General anesthesia was induced with iv propofol 2 mg∕kg, rocuronium 0. 6 mg∕kg and sufentanil 0. 2 μg∕kg. The patients were endotracheally intubated. The concentration of sevoflurane inhaled was adjusted according to the value of bispectral index, and bispectral index value was maintain at 40-50. Ondansetron 8 mg and flurbiprofen axetil 100 mg were injected intravenously at 30 min before the end of surgery. If vomiting occurred for 2 consecutive times, and continuous nausea and vomiting appeared from the time point after extubation to 24 h after surgery, and the patients required treatment, rescue medication was used. The occurrence and severity of PONVwithin 24 h after surgery and requirement for rescue medication were recorded. Results Compared with non?chemotherapy group, the incidence of PONV within 24 h after surgery and requirement for rescue medication were significantly increased, and the severity of PONV was aggravated in neoadjuvent chemotherapy group (P<0.05). Conclusion Neoadjuvant chemotherapy before surgery can increase the risk and severity of PONV after modified radical mastectomy.

Objective To determine main factors associated with quality of life in epileptics in northen China especially seizure severity and stigma, and the variations between men and women. Methods All patients with epilepsy aged 18-65 years were selected from the First Affiliated Hospital of China Medical University, tested from March 2014 to March 2015. All of them completed the general social science data, the Quality of Life Inventory in Epilepsy-31 (QOLIE-31), Liverpool Adverse Events Profile (LEAP), the National Hospital Seizure Severity Scale (NHS3), Epilepsy Stigma Scale (ESS), Self-rating Anxiety Scale ( SAS) and Hamilton Depression Scale ( HAMD) assessment. Results A total of 123 patients with epilepsy (60 men, 63 women) were interviewed. QOLIE-31 scores were 55. 81 ± 10. 17 in female patients, 65. 35 ± 10. 89 in male patients, the difference being statistically significant (t=2. 90, P<0. 05). ESS (1(0,2)), SAS(31. 85 ± 8. 16), HAMD (4. 38 ± 2. 90) scores of female patients were higher than that of male patients (0(0,0), 26. 93 ± 3. 45, 2. 80 ± 1. 39;U= -2. 710, t=2. 48, 2. 20, all P<0. 05). Multiple factors analysis and multiple stepwise regression analysis on quality of life revealed that depression (β= -0. 516, P<0. 01) and the severity of epilepsy (β= -0. 338, P=0. 01) were two strong predictors of QOLIE-31 overall scores. The linear regression showed that there was a direct link between shame and degree of depression (β = 0. 515, P= 0. 001 ) . Conclusions The main factors affecting the quality of life in epileptics in northen China are depression and seizure severity. Compared with male patients, female patients have a lower quality of life, and poorer psychological status, such as shame, depression and anxiety. There is a direct link between shame and depression in epileptics.
