To cure one patient with spinal cord injury (SCI), who hospitalized for both legs couldn't moving for 21 years after external injury, by using the olfactory ensheathing cells (OECs) transplant and acupuncture treatment. The patient was diagnosed as ischemic SCI (below the T11) according to the neurological test and MRI for dorsal vertebra. T11 spinous process was made to be the center mark through operation with the length of about 3 cm. The area between the atrophique spinal cord and normal spinal cord without vessel was selected and injected with OECs 0.5?109 L-1. Hemostasis, stitching, binging and fixation were performed respectively, and normal treatment was given by using antibiotics. At 14 days after operation, the temperature on skin increased a little, and acupuncture treatment and rehabilitation therapy were performed. The acupoints were as following: Baihui (DU21), Yintang (EX-HN3), Hegu (LI4), Zhongji (RN3), Guanyuan (RN4), Biguan (ST31), Fengshi (GB31), Futu (ST32), Dubi (EX-LE5), Zusanli (ST36), Xuehai (SP10), Yinlingquan (SP9), Sanyinjiao (SP6), Jiexi (ST41), Taixi (KI3), Fuliu (KI7), Taichong (LR3), and Shenmai (BL62). The treatment was given by mild reinforcing and attenuating with 30-minute retention. The rehabilitation: The needle pressing, manipulation for muscular atrophy, bicycle practicing, andimperative standing were performed. After 2 weeks, the skin temperature of the patient increased with obvious improvement in his right leg. The physical strength of the patient was reinforced with less perspiration, and the patient could walk 3 km without fatigue, which indicated that after OECs transplant, treatment with acupuncture, massage and other rehabilitation trainings could facilitated the improvement of SCI of the advance stage as well as the amelioration of muscular atrophy.

Objective To evaluate the imaging features of phyllodes tumor of the breast.Methods 35 patients with phyllodes tumor of the breast confirmed by surgery and histopathology were collected.All clinical and imaging findings were analyzed.Results 35 cases with 36 lesions were classified as benign (1 9 lesions),borderline (8 lesions),and malignant (9 lesions).The typical ap-pearances on mammography were ellipse (1 6/36)or lobulated (20/36)mass.Most of them were high density (30/36)and clear boundary (28/36).No evidence of calcification,spiculated margin,skin thickening,nipple retraction and enlargement of axillary lymph nodes were detected.On MRI,1 lesion presented as lobulated mass with nonuniform hypointensity on T1 WI,hyperintensity on T2 WI and DWI.The time-intensity curve was Ⅱ type on dynamic contrast enhancement MRI.Conclusion The clinical and ima-ging features of phyllodes tumor are characteristic.These features are helpful to preoperatively diagnose,the final diagnosis would confirmed by histopathology.

Aiming at the single treatment and the design separation between treatment and assessment in electrotherapy equipment, a kind of system including low-intermediate frequency treatment and efficacy evaluation was developed. With C8051F020 single-chip microcomputer as the core and the circuit design and software programming used, the system realized the random switch of therapeutic parameters, the collection, display and data storage of pressure pain threshold in the assessment. Experiment results showed that the stimulus waveform, current intensity, frequency, duty ratio of the system output were adjustable, accurate and reliable. The obtained pressure pain threshold had a higher accuracy (< 0.3 N) and better stability, guiding the parameter choice in the precise electrical stimulation. It, therefore, provides a reliable technical support for the treatment and curative effect assessment.

Objective To explore and evaluate the clinical value of MRI for status of axillary lymph node after neoadju-vant chemotherapy (NAC) in patients with breast cancer. Methods Forty-four patients with 1ocally advanced breast cancer (LABC) were underwent NAC for four cycles. The longest diameter of axillary lymph node (ALN) measured by MRI scan. Val-ue of apparent diffusion coefficient (ADC) and their correlation were compared before NAC and four cycles after NAC. Re-sults of MRI and pathological data for ALN were compared between two groups of patients. Results All patients finished four cycles of NAC. The total response rate (CR+PR) was 72.7% (32/44), and the total non-response rate (SD+PD) was 27.3%(12/44). The longest diameter of ALN was significantly shortened in response group. The longest diameter was (1.37± 1.06) cm before NAC and (0.90±0.76) cm after NAC (P<0.01). The ADC value of the tumor was significantly increased in re-sponse group [(0.91±0.28) ×10-3 mm2/s before NAC and (1.01±0.32)×10-3 mm2/s after NAC, P<0.01)]. There was no signifi-cant correlation between ADC value change (△ADC) and the longest diameter change of ALN (△L, r=0.131, P=0.413). The sensitivity, specificity and Kappa value of ALN evaluation after NAC were 100%, 62.5%and 0.68 measured by MRI. Con-clusion The change of tumor longest diameter reflects the effect of chemotherapy directly. The tumor ADC value of MRI can not be used as an independent indicator of chemotherapy effect of ALN, eventhouth MRI was the sensitive index for eval-uating the status of axillary lymph node after neoadjuvant chemotherapy for breast cancer.

BACKGROUND: Previous studies demonstrated that,metabolic phenotype of cytochrome P450 2C19 has genetic polymorphism,which presents with extensive or poor metabolisms and has great differences in races and individuals.OBJECTIVE: To study the genotype distribution of cytochrome P450 2C19 in Xinjiang Uigur population.METHODS: In total 144 unrelated Uigur and 156 unrelated Han subjects were genotyped for cytochrome P450 2C19 by polymerase chain reaction-restriction fragment length polymorphism.The differences of gene phenotype and gene frequency were compared between Uigur and Han populations.RESULTS AND CONCLUSION: The frequency of extensive metabolism wt/wt,wt/m and wt/m1+wt/m2 of Uigur was notably higher than that of Han population(P<0.05),but the frequency of poor metabolism m1/m1 was obviously lower than that of Han population(P<0.05).There were significant differences between Uigur and Han populations in allele frequency wt,m1 and m2(P<0.05),especially m1,which was 58-fold of m2(P<0.01).The results revealed that,distribution frequency m1/m1 of poor metabolism of Uigur is obviously lower than that in Han population,and m1 frequency is higher than that of Han population,accordingly,m1 is the main gene mutation of cytochrome P450 2C19 in Uigur population.

OBJECTIVE To study the optimal reagent for regeneration of aptamer-coated piezoelectric quartz crystal chips and detect storage ability of aptamer-coated chips. METHODS Anti-IgE aptamers were immobilized on the gold surface of piezoelectric quartz crystal biosensor with biotin-avidin method. The reaction between anti-IgE aptamers and IgE was monitored in time on piezoelectric sensor. We tried to regenerate the sensor surface after binding IgE by rinsing the aptamer-coated chips with HCl, NaOH, EDTA, urea and formamide individually. Aptamer-coated chips were stored in PBS with 0.1% sodium azide and the stored chips were used to detect IgE in 35 days. RESULTS Of the five reagents, EDTA was the best one for regeneration of aptamer-coated chips and the sensor could retain 91.5% of the original detecting signals after five regeneration cycles. Moreover, the aptamer-coated chips could be stored in the binding buffer for 21 days without obvious loss of activity. CONCLUSIONS Compared with antibody-based piezoelectric sensor, aptamer-based sensor has lower cost, more regeneration cycles and longer time for the storage of chips. This series of experiments shows the superiority of aptamer detection.

OBJECTIVE To establish an aptamer-based piezoelectric sensor assay to detect human immunoglobulin E (IgE) and acquire the parameters about this kind of biosensor. METHODS Anti-IgE aptamers were immobilized on the gold surface of piezoelectric quartz crystal sensor with biotin-avidin method. The reaction between anti-IgE aptamers and IgE was monitored in time on piezoelectric sensor. Different concentrations of IgE were detected and the calibration curve of IgE was drawn. Non-specific response signals of BSA, IgG and IgE were monitored to show the detecting specificity of aptamer-based sensor. RESULTS For the aptamer-based sensor, the lowest limit of detection was 0.055mg/L and the linear range was 0.1-2.5mg/L. Non-specific signals of this sensor were less than 5% of specific signals of IgE at the same concentration. CONCLUSIONS The aptamer-based piezoelectric sensor can detect 5.5 ng IgE while the non-specific signals are very low. So this aptamer-based sensor is hopeful to be applied to clinical laboratory diagnosis.
