Adipose-tissue mesenchymal stem cells, is one kind of multipotent stem cells, can differentiate into adipogenic, osteogenic, chondrogenic, myogenic cells and so on in vitro and in vivo. Human adipose tissue is plentiful, easily harvested in large quantity with little patient discomfort. Adipose-tissue derived mesenchymal stem cells may be an alternative stem cell source for mesenchymal tissue regeneration and engineering without ethical consideration of embryonic stem cells and severe pain resulted by bone marrow procurement. The research work on adipose-tissue mesenchymal stem cells and future clinical perspectives were reviewed.

To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

ObjectiveTo investigate the safety and efficacy of carbon dioxide ( CO2 ) insufflation during ERCP.MethodsBetween January and August 2011,a total of 102 consecutive patients who underwent ERCP were randomized to accept CO2 insufflation ( n =52 ) of air insufflation ( n =50 ) during the procedure.ERCP was carried out with the same instrument by an expert endoscopist who was blinded to the insufflation gas used and the procedure was controlled at 30 minutes to 1 hour.The heart rate,oxygen saturation of the patient was continuously monitored during the procedure.Before the procedure and 1 hour after the end of operation,abdominal X-ray was taken to evaluate the width of intestine,and the degree of intestinal expansion was defined as normal,mild,moderate and severe according to the width increased.A questionnaire with 100 mm visual analogue scale (VAS) was used to quantify the abdominal pain and distention experienced at 1 hour,2 hours,and 6 hours after the procedure.The patients' vital signs,bowel dilatation,the average operating time,abdominal pain score and distention score on VAS,and complications in 2 groups were analyzed.ResultsThe baseline characteristics of 2 groups were comparable.ERCP was successfully performed in all the patients and no complication was observed.In CO2 group,the average operating time,mean heart rate and oxygen saturation were (45.2 ± 10.6) min,( 102.2 ± 10.3 ) bpm and ( 99.5 ± 0.5)％,which were (48.5 ± 11.2) min,( 100.3 ± 11.4) bpm and (98.9 ±0.6)％,respectively,in air group.There were no significant differences on these items between the 2 groups ( P ＞ 0.05 ).Moderate to severe intestinal expansion 1 hour after ERCP was found in 14 patients (26.9％ ) in CO2 group and in 28 patients (56.0％ ) in air group,and the latter was significantly higher than the former (x2 =11.61,P =0.009).Both of the mean abdominal pain and abdominal distention scores at 1 hour post-ERCP in CO2 group were lower than those in air group,but without significant difference (P ＞0.05).However,the mean abdominal pain scores at 2 hours and 6 hours post-ERCP in CO2 group were significantly lower than those of patients in air group (7.4 ±2.2 vs.18.7 ±4.6 at 2 hours post-ERCP,9.6 ±3.7 vs.20.1 ±4.5 at 6 hours post-ERCP,all P ＜ 0.05 ).Similarly,the mean abdominal distention scores at 2 hours and 6 hours post-ERCP in CO2 group were significant lower than those of patients in air group (7.6 ±3.6 vs.18.3 ±4.1 at 2 hours post-ERCP,8.9 ±3.7 vs.19.4 ±4.2 at 6 hours post-ERCP,all P ＜0.05).ConclusionThe use of CO2 insufflation instead of air during ERCP appears to be safe.Insufflation of CO2 during ERCP palliates the intestinal expansion,post-ERCP abdominal pain and distention comparison to insufflation of air.However,because of the single-center clinical observation with limited number of cases,the safety and efficacy of CO2insufflation during ERCP requires to be further evaluated.

OBJECTIVE:To establish the system of curriculum based on working process and occupation ability for pharmacy major in higher vocational colleges. METHODS:Investigation was conducted among medical practitioners from pharmaceutical companies,hospitals,pharmaceutical factories,scientific research institutions and other related professionals. RESULTS:150 ques-tionnaires were sent out,and 141 valid questionnaires were collected with effective recovery rate of 94.00%. Results of investiga-tion showed that respondents most valued graduates with interpersonal and communication skills,followed by professional skills and practical ability. They were mainly clinical application of drugs,pharmacological effects and adverse reactions of drugs in the pharmacology theory teaching,the mechanism of action of drugs were weakened. The ability of prescription distribution,symptoms inquiring and drugs recommending should be strengthened in the pharmacology theory practice teaching. More than half of the re-spondents thought that confirmatory tests were necessary to keep,which helped to train students’practical ability and deepen the understanding of the theory. Meanwhile,it was important to strengthen the students’communication with the patients or their fami-lies and doctors to cultivate the ability of acquiring professional knowledge. CONCLUSIONS:The investigation provides basis for the making of curriculum standards of pharmacology,through which teaching contents are selected,teaching methods are de-signed,and it makes the pharmacology course full of post applicability and provides better decision-making basis to meet the posi-tion requirements.

Objective To compare the efficacy of insulin aspart and human soluble insulin on postprandial glucose control and blood glucose excursion in type 2 diabetic patients managed with insulin pump therapy. Methods All of 345 hospitalized type 2 diabetic patients were randomized divided into two groups. One group underwent insulin pump therapy with insulin aspart (aspart group, 173 cases),another group with human soluble insulin (humulin R group, 172 cases). Capillary glucose concentrations were measured at 9 time points,including preprandial,2 hours postprandial,bedtime (22:00),midnight(0:00) and 3:00 every day during the treatment. The change of blood glucose at each time point and the variation of postprandial blood glucose excursion was compared between the two groups. The frequency of hypoglycemia was also evaluated. Results After treatment, fasting blood glucose and post breakfast and post dinner blood glucose levels were decreased more significantly in the aspart group than those in the humulin R group. And a significantly smaller postprandial blood glucose excursion was shown in the aspart group compared with that in the humulin R group (P< 0.05). The time to achieve good glycemic control in the aspart group was (4.40 ± 2.16) d, significantly shorter than that in the humulin R group[(5.68 ± 2.29) d](P< 0.05). The incidence of hypoglycemia was significantly lower in the aspart group (P <0.05). Conclusion Insulin aspart results in better control of blood glucose and less glycemic variability compare with human soluble insulin in type 2 diabetic patients during delivery by continuous subcutaneous insulin infusion.

Objective: To explore the acute effect of air pollution on mortality for patients with cardio cerebral vascular disease and to provide the basis for disease prevention and control.
Methods: The Mortality for patients with cardio cerebral vascular disease from 2001-01 to 2009-12 was from Tianjin Centers for Disease Control and Prevention, the meteorological and air pollution data were from Tianjin meteorological bureau and Tianjin environmental monitoring station respectively. The Single and multiple generalized additive model (GAM) extended poisson regression analysis was performed to calculate the relationship between air pollution and cardio-cerebral vascular disease mortality by controlling the time trends, weather, the day of week and air population.
Results: Results: Single GAM analysis indicated that when the effect of SO2, NO2 and PM10 in the air reached the maximum in the day, the RR values for the mortality in patients with cardio-cerebral vascular disease increased 1.13%[95%CI (0.76-1.51)%], 0.78% [95%CI ( 0.41-1.15)%] and 0.61% [95%CI ( 0.51-0.71)%] respectively; when the average concentration of SO2, NO2 and PM10 increasing 10μg/m3 per day, after 0-5 days, the RR values for the mortality elevated 0.70% [95%CI (0.47-0.94)%], 0.51% [95%CI (0.27-0.74)%] and 0.16% [95%CI (0.06-0.27)%] respectively. Multiple GAM analysis presented that when SO2, NO2 and PM10 increasing 10 μg/m3 per day, the RR values for the mortality elevated 0.77% [95%CI (0.58-0.97)%], 0.41% [95%CI (0.05-0.78) %] and 0.38% [95%CI (0.12-0.64%)%] respectively.
Conclusion: The air pollution could increase the mortality risk in patients with cardio-cerebral vascular disease, it is necessary to establish the prevention system in order to decrease the mortality risk in those patients.
