Cytokine induced killer (CIK)cells are immune effector cells generated from mononuclear cells induced by many cytokines.CIK cells have several advantages, such as rapid proliferation, broad spectrum killing activity, high tumoricidal activity and non-major histocompatibility complex restriction.Recently, cord blood derived CIK cells have attracted extensive concerns because of its faster proliferation, higher tumoricidal activity and lower incidence of GVHD compared with adult peripheral blood derived CIK cells. This paper will review the biological characteristics, clinical application and research advances of cord blood derived CIK cells.

Objective: To explore the differences between the internal social adaptation and external social behaviors of freshmen. Methods: Make a survey of 198 freshmen on the internal adaptation and external by General Well-Being Schedule and Undergraduate Social Adaptation Questionnaires. Results:Freshmen' social adaptation mainly involves three factors: interpersonal communication, the state of campus life and performance of studies. The Cronbach alpha of 3 factors were 0.82, 0.87 and 0.90,and the re-test reliability was r=0.73 (P

AIM: To investigate law of vacuum drying process and provide basic technical supports for drying process and design of drying machine. METHODS: A batch-drying experiment system was used to continuously record the mass and temperature of the drying sample,then the key effective factors and characteristics of different phase of drying process were obtained based on the analysis of the recorded experimental data. RESULTS: The influence of process parameters on evaporation rate varied in different period of drying process. CONCLUSION: In order to improve the efficiency of the integrated drying process,it's necessary to apply appropriate technical methods according to the characteristics of the process.

Objective To summarize the related factors and nursing countermeasures of complications after the laparoscopy-assisted surgery for congenital hypertrophic pyloric stenosis.Methods Clinical data about the occurrence of complications and nursing points were retrospectively analyzed in 106 cases of neonates and infants.Results Surgical complications occurred in 16 cases,including mucosal perforation in 2 cases,abdominal cavity hemorrhage in 1 case,puncture hole infection in 1 case,repeated postoperative vomiting caused by incomplete pyloric separation in 1 case,postoperative hypercapnia in 2 cases,subcutaneous emphysema in 1 case,8 cases of postoperative hypothermia.No operative deaths.No poking holes hernia and abdominal organ injury.By careful observation and nursing,all cases got rid of postoperative complucations.Within postoperative 3～7 days,they were recovered and discharged,no nursing complications occurred.Conclusions Early discovery of complications and timely nursing intervention are important guarantee for patients to pass through laparoscopic surgery smoothly and obtain swift recovery.

Objective To discuss Buyang-huanwu decoction preventing the formation of lower limb deep vein thrombosis (DVT) after major orthopedic surgery.Methods 60 patients were randomly divided into a treatment group and a control group.The treatment group was treated with oral liquid of Buyang-huanwu,twice a day; while the control group was treated with 5000IU of low molecular heparin through subcutaneous injection,once daily.Prothrombin time (PT),activated partial thromboplatin time (APTT),fibrinogen (FIB),D-dimer,lower limb deep vein color B ultrasonic and the wound flow changes after 48 hours were observed at 1st,7th,and 14th day after medication.Results ①)Comparison on the incidence of DVT:The incidence of DVT in the treatment group was higher than the control group at 7th day after medication,this incidence turn to equal in the two groups at the 14th day after medication,while at the end of therapy,the incidence of DVT in the treatment group was lower than the control group with significant difference (P＜0.05).②Comparison on D-dimer changes:D-dimer at the 1st and 14th day were (0.782 ± 0.472) mg/1 and (0.320 ± 0.102) mg/1 in the treatment group and (0.720±0.421)mg/1 and (0.417 ± 0.217) mg/l in the control group.Comparing with the same group before treatment [the treatment group was(0.548±0.245)mg/1; the control group was (0.560±0.195) mg/l],D-dimer was increased at the 1 st day with obvious difference (P＜ 0.05),but reduced at the 14th day,without statistical difference (P＞0.05).Conclusion Buyang-huanwu decoction did not show good effects as low molecular heparin at the beginning of the treatment,but the its whole therapeutic effects and safety was better in treating lower limb deep vein thrombosis after major orthopedic surgery.

Objective: To study the ecological suitability of Angelica sinensis growing in Gansu Province and guide the rational cultivation. Methods: Through visiting and field investigation, 1 545 batches of Chinese angelica samples were collected from the county areas in Gansu Province. The information about the longitude, latitude, altitude of each sampling point was collected by using the GPS, combining with national environmental factor data, and using Maxent model and spatial analysis function of ArcGIS software. Results: The areas with high suitability of A. sinensis distribution are in the southeast of Gansu Province. The main ecological factors affecting the suitability distribution of A. sinensis were altitude, rainfall in March, May and December, wettest month precipitation, soil pH and other ecological factors. Conclusion: The research findings are basically consistent with the living habits of A. sinensis that cultivated in high-cold mountain areas and plateau flat pasture areas with a cool climate, moderate soil, moisture, slightly acidic to neutral fertile and loose brown sandy loam soil. This result can provide scientific basis for the reasonable distribution of A. sinensis cultivation area in Gansu Province.

AIM: To investigate the effectiveness of dosing technology and excipient application on solid drug's moisture-proof property and to provide a method improving the solid drug's moisture-proof property. METHODS: Based on the analysis of the moisture absorbing process and the absorbing mechanics,a new concept "active moisture absorbance site"(AMAS) was defined and mathematic model was constituted.Two constants as: initial AMAS concentration C_0,moisture resistance coemcient K,were proposed to indicate the drugs moisture-proof ability. The CI WU JIA extracts and SHUANG HUANG LIAN extracts were used to conduct experiments, which were designed to investigate the improvement of the drug's moisture resistance ability when varying the AMAS's concentration and/or its space distribution. RESULTS: Reducing the amount of moisture absorbance excipients in each dosage of solid drug can lower the drug's moisture absorbance ability,and applying a thin film coating material outside the drug can also slow the drug's moisture absorbance rate. CONCLUSION: The proposed mathematic model is useful for finding a way to improve the drug's moisture resistance;experimental data shows that the drug's moisture-proof property would be improved by reducing the amount of moisture absorbance excipient in each dosage and improving the moisture distribution resistance through a certain dosing technology,such as film coating technology.
