Objective To analyze the postoperative complications in aged patients receiving pancreaticoduodenectomy. Methods Pancreaticoduodenectomy was employed for the treatment of 52 aged patients. Of the 52 patients with a mean age of 70.5(65-76), 32 were male and 20 female. Postoperative pathological examination confirmed that 24 patients suffered from Vater,s ampullary and duodenal cancers, 16 from pancreatic carcinoma and 12 from cholangiocarcinoma. Results The mortality was 7.7%. Severe complications included bleeding (upper gastrointestinal tract or abdominal cavity),MOF, ARDS, postsurgical gastroparasis syndrome(PGS), mental disorder, pancreaticogastrostomy leak and biliary-enteric anastomotic leak et al. Conclusion MOF is the main lethal complication. Incidence of PGS and mental disorder is high.

Objective　To study the effects of MIP-1β and TGF-β antibody on CD34+ cells from cord blood in stroma-contact culture system. Methods　Immunomagnetic selected CD34+ cells were inoculated onto the pre-established irradiated human stroma layer. MIP-1β, TGF-β antibody (20 μg/ml) and MIP-1β+anti-TGF-β (5 μg/ml) were added on day 0 and day 5. On day 5 and day 10, cell counting, hematopoietic progenitor cells count were made by semi-solid culture and CD34+ cells were assayed by FACS. Results　On day 5, no significant difference of total cell number was observed as compared with the control group (P>0.05), but the number of CD34+cells, CFC, and HPP-CFC in TGF-β antibody and MIP-1β+ TGF-β antibody groups was significantly higher than that in the control (P<0.05). On day 10, the number of total cell, CD34+ cells, CFC, and HPP-CFC in TGF-β antibody and MIP-1β+ TGF-β antibody groups was significantly higher than that in the control (P<0.05). No significant difference was observed between groups MIP-1β and control either on day 5 or day 10 (P>0.05). Conclusion　MIP-1β has no significant effect on the CD34+ cells as compared with the control while the CD34+ cells can be expanded 1-3 folds with TGF-β antibody (20 μg/ml) or MIP-1β+ TGF-β antibody (5 μg/ml) in 10 days. There are synergic interactions between MIP-1β and TGF-β antibody.

Purpose To study the therapeutic methods of fatigue syndrome. Methods Seventy-nine cases of fatigue syndrome were treated by Tuina manipulation and a comprehensive assessment of main complaints and accompanied symptoms was made. Results After 3month's Tuina treatment, 21 cases were cured, 43 cases improved, 15 cases obtained no effects. Conclusion Tuina has a unique therapeutic effect on fatigue syndrome.

BACKGROUND:Meniscus injury is a common disease, whose curative effect is not obvious. The clinical application of tissue engineering technology is gradual y rising, and mesenchymal stem cells-stents complex is expected to be used for the treatment of meniscus injury.
OBJECTIVE:To review the application process of mesenchymal stem cells-stents complex in meniscus injury, in order to provide reference for further study and clinical practice.
METHODS:A computer-based online search of PubMed database, VIP database, Wanfang database and China National Knowledge Infrastructure between 1980 and 2013 was performed to search related articles on mesenchymal stem cells-stents complex in meniscus injury. The key words were“mesenchymal stem cell, meniscus injury, tissue engineering, scaffold, stent”in English and“mesenchymal stem cell, meniscus injury, tissue engineering”in Chinese. For the articles in the same field, we preferred the ones published recently or in authorize journals. Meta-analysis and repetitive studies were excluded. 282 articles were included, and final y 59 articles were included according to inclusion criteria.
RESULTS AND CONCLUSION:Nowadays, numerous experiments showed that mesenchymal stem cells could differentiate into chondrocytes both in vivo or vitro. Mesenchymal stem cells-stents complex could be effective to meniscus injury. Although this technique is stil in exploratory stage, it has promising application prospects in treatment of meniscus injury, because it is characterized by convenience to col ect samples, vitality and no antigenicity.

Objective: To observe the clinical efficacy of combining acupuncture and medication in treating chronic atrophic gastritis (CAG) due to spleen-stomach deficiency.
Methods: Totally 176 patients with CAG were randomized into two groups by the random number table. The 91 subjects in the treatment group were intervened by acupuncture and oral Chinese patent medication; the other 85 subjects were by oral Chinese patent medication alone. The clinical efficacies were compared at the end of intervention.
Results: After a treatment course, the total effective rate was 87.9% in the treatment group versus 75.3% in the control group; according to the gastroscopy and pathological biopsy examinations, the total effective rate was 85.7% in the treatment group versus 74.1% in the control group. There were significant differences in comparing the clinical efficacy, gastroscopy and pathological examinations between the two groups (P<0.05).
Conclusion: Combining acupuncture and medication can produce a better therapeutic efficacy than medication alone in treating CAG due to spleen-stomach deficiency.

Objective To study the processing method,extraction technology and quality evaluation analysis of Paeonialactiflora Pall, so as to provide reference for selecting the best method and improving its quality .Methods One year and 3 years Chinese herbal medicine Paeonialactiflora Pall was used.The use of raw materials and cooked products for processing methods to paeoniflorinas the representative , and the content was determined by high performance liquid chromatography.With the optimization of orthogonal test, the methods for the determination of effective components of radix paeoniaealba were summarized and the quality control methods were analyzed .Results The content of paeoniflorin in raw paeonialactiflora pall was (6.33 ±0.52)%,and the content of paeoniflorinin cooked Paeonialactiflora Pall was (5.74 ±0.45)%, which was with statistical significance(P <0.05).The content of paeoniflorin in raw paeonialactiflora pall was (5.90 ±0.38)%,and 4.85 ±0.45% in three years cooked paeonialactiflora pall, and the differenceswere with statistical significance(P<0.05).Extracted three times with 70% ethanol, time 65 min, 6 times the amount of solvent,the paeoniflorin high cream rate was highest.By means of induction, several active ingredients should be screened out to control the content of paeonialactiflora pall to publish multiple indicatorsquality control methods .Conclusion The preparation method of Chinese herb paeonialactiflora pall has showed that the active ingredient content is morein raw herb.To establish quality control method of multiple indicators of paeonialactiflora pall based on raw herb,gradually improve the quality of more comprehensive paeonialactiflora pall quality control model.To optimize the extraction of Chinese herbal medicine,provide scientific reference for the sustainable utilization and industrial production of paeonialactiflorapall.
