Cytokine induced killer (CIK) cells are the main immune cells for tumor immnuotherapy.Relevant basic researches show that CIK cells have significant antitumor effects for various hematologic tumor and solid tumors.Clinical studies confirm that CIK cells-based therapy have exact therapeutic effect and mild adverse reaction for tumor patients.So CIK cells-based therapy is a promising and safe method and it is important to establish standards for cultivating and using CIK cells.

Objective To explore the efficacy of selective posterior rhizotomy (SPR)and post-operative rehabilitation training in treating cerebral palsy. Methods The 100 patients with cerebral palsy were randomly divided into two groups. In group A, the patients were treated by SPR, and in group B, the patients received rehabilitation training after SPR for 12 months. One year later the curative efficacy of all patients was evaluated and compared between the two groups.Results The effective rate was 52% and 76% in groups A and B respectively. Conclusion It is very important that the patients receive systematic rehabilitation training after SPR so as to gain a most satisfied functional recovery.

This paper introduces the development of the MEMS at home and abroad,besides the key technology,the application in medicine and military about the MEMS also expounded in detail.

Objective To investigate the clinical value of a three-dimensional motion analysis system by using the body segmental method for testing the balance of hemiplegic stroke patients.Methods Twenty stroke patients with hemiplegia were measured using the lower extremity Fugl-Meyer motor assessment (FMA-L),the Brunel balance assessment (BBA),the Berg balance sale (BBS) and a 5 m timed up-and-go test (5m-TUGT).The three-dimensional motion analysis system using the body segmental method was applied in three positions-sitting,standing and walking.Spearman's rank correlation coefficient was used to determine the extent of correlation between the values measured by the three-dimensional motion analysis system and the FMA-L,BBA,BBS and 5m-TUGT results.Results Some motion analysis variables (MSAx,MSVx,MSAy,MSVy and SPxy,SP3-D) are recorded in sitting and standing,while the center of gravity (COG) swing in the horizontal plane and some other variables (MSAx,MSVx and SPxy and SP3-D) are measured while walking.Anterior-posterior COG swing had a high negative correlation with the FMA-L,BBA and BBS scores and a high positive correlations with 5m-TUGT times.But except in sitting,MSAz and MSVz were both uncorrelated with FMA-L,BBA or BBS scores or with 5m-TUGT times.COG swing in the horizontal plane in sitting and standing apparently correlates with lower extremity motor function,balance,and walking ability.However,only the X axis swing parameters of the COG while walking correlated with lower extremity motor function,balance or walking ability.Conclusions A three-dimensional motion analysis system using the body segmental method can be used clinically to monitor patients' balance in real time and dynamically in different positions and activities,and it can be used to predict motor function and balance control in hemiplegic stroke patients.

Objective To investigate the effects of 810 nm semi-conductor laser irradiation on the proliferation of olfactory ensheathing cells in vitro. Methods Olfactory ensheathing cells obtained from adult rat olfactory mucosa using the method based on different rates of attachment were irradiated with a semi-conductor laser ( wave length 810 nm; power density 10.3 mW/cm2) for 30, 60 or 120 seconds. Laser irradiation was performed 3 times with a 24 h interval. After the last irradiation, the cells were cultured. At the 3rd, 5th and 8th day of cell culture,cell proliferation was assessed with cell counts and a methylthiazoletetrazolium ( MTT) colorometric method. Results After 3 days of cell culture, the number of cells and average MTT values showed no statistically significant difference between the irradiated and control groups. At the Sth and 8th day, the differences among all the laser exposure groups and with the control group were significant, except for the average MTT values of the control group and the 30 s exposure group. Maximal effect was achieved with a 60 s exposure. Conclusions Low power laser irradiation can stimulate the proliferation of olfactory ensheathing cells in vitro, and the effect is time-dose dependent. The optimal irradiation time was found to be 60 s daily for 3 times, with a 24 h interval.

The HER-2/neu gene, also named c-erbB-2 or erbB-2, is proto-oncogene of v-erbB-2 which was firstly discovered in 1985. Many studies have been reported since that amplification of the HER-2 gene in breast tumors is associated with poor prognosis was recognized. The relevant knowledge of HER-2/neu gene is summarized in this article.

Objective To explore the expression of ribosomal protein L6 (RPL6) in prostate cancer and its clinical sig-nificance. Methods RT-qPCR and Western blot assay were used to measure the mRNA transcription and protein expres-sion levels of RPL6 in prostate cancer tissues (n=80) and adjacent non-cancerous tissues (n=62). The relationship between RPL6 mRNA expression level and clinicopathological factors of prostate cancer was statistically analyzed. Results The mRNA and protein expression levels of RPL6 were significantly higher in prostate cancer tissues compared with those of non-cancerous tissues (P<0.05). There were higher serum expression levels of prostate specific antigen (PSA) and higher Gleason score in prostate cancer tissues. The expression level of RPL6 mRNA was significantly higher in patients with lymph node metastasis and late clinical stage (P<0.05). There were no significant differences in PSA levels between different ages, with or without seminal vesicle invasion and different surgical margin status (P>0.05). Kaplan-Meier survival analysis of biochemical recurrence (BCR)-free survival time showed the significantly lower recurrent rate in patients with high RPL 6 mRNA expression(χ2=4.530,P=0.033). Conclusion The elevated expression of RPL6 may play a role in the development of prostate cancer, and which can be used as a tumor marker to assess the prognosis of prostate cancer.

Objective:To find out the key demand and connection point of health quality education for students of different stages by analysis of their health quality characteristics and the main contribution path, and then explore strategies to improve health quality. Methods:The stratified random cluster sampling method was carried out to select the sample population in Hangzhou. The variance analysis, curve fitting and multivariate linear regression analysis were used to analyze health quality characteristics and the main contribution path. Results:The health quality of pri-mary school students was best;the difference in quality between college students and junior high school students was not statistically significant ( P>0. 05 );and high school students had the worst health quality. The high school stage is the weakest link of health quality education. The order of the health education path and the means for improving the health quality of college, high school, and primary school students differ. With the improvement of students’ lev-el, the students that require physical quality promotion gradually decreases; the moral quality demand remains sta-ble;and the psychological quality and social adaptation ability present the tendency of a gradual increase. Conclu-sion:Student health quality shows a tendency to decreases with the rise of learning phase. The education departments should foster health consciousness and habits for students, form a healthy lifestyle behavior and ways of thinking for high school students, shape healthy personalities to improve health literacy and social adaptation abilities for college student, which is the key strategy for promoting the health quality of all-round development of the students and a-chieve the primary education goal of “health education”.
