Objective To study effect of racing training on 54 paraplegic ability of driving wheel-chair. Method 54 paraplegics paticipated in the wheel-chair racing training. Result The subjects drived wheel-chair more powerfully and faster than before, and pushed up step and ramp easily. Conclusion Wheel chair racing training is an effective method of improving the driving ability.

[Objective] To observe the clinical effect of Bupleurum injection external application applied to female genital condyloma accuminatum cases. [Methods] From January 2010 to June 2013,we studied 60 female genital condyloma accuminatum cases in the outpatient department of our hospital, these cases were randomly divided into two groups:group A(Bupleurum injection group) and group B(ShuRun suppository, namely a-2a interferon suppository group), the clinical curative effect of the two groups was observed. [Results] After treatment, group A,30 cases in al ,9 cases had complete recovery,12 cases had some effect,9 cases were invalid, the total effective rate was 70%; group B,the total of 30 cases,6 cases had complete recovery, 7 cases had some effect, 17 cases were invalid, the total effective rate was 43.3%, group A in the treatment of female genital condyloma acuminatum had better effect than the group B(P<0.05).After treatment,the total score of two groups al reduced effectively.The recurrence rate had no obvious difference between the two groups(P>0.05). [Conclusion] Bupleurum injection for treating female genital condyloma acuminatum has better clinical efficacy, can be considered for clinical use.

This paper outlines some molecular marking technology based on rDNA sequences and several DNA fingerprinting technology (RAPD, ARDRA, AFLP, REP/ERIC-PCR) used in classification, identifica-tion and diversity research in lactic acid bacteria. The principles, methods and progress in recent years of these technologies were also introduced. At the same time, this paper also compares the advantages and dis-advantages of these methods. People should choose suitable method according to their purposes.

Opioid dependence is based on compensatory adaptations in neurons following chronic exposure to opioids. Recent researches show antagonists of N methyl D aspartate (NMDA) receptors inhibit physical and psychic dependence on opioids. This review focuses on the interactions between opioid receptor system and NMDA receptor system, and on the molecular mechanisms of NMDA receptor contributing to opioid dependence. The clinical prospects of NMDA receptor antagonists and related substances on preventing and treating opioid dependence are aslo discussed.

Objective To investigate the efficacy,side effects and cosmetic effects of breast-conserving operation combined with radiotherapy for patients with breast cancer. Methods Forty-three patients with early stage of breast cancer(n=30 for stage I and n=13 for stage II) were performed extended resection plus axillary lymph node dissection or quadrant resection plus axillary lymph node dissection.After operation,tangential field irradiation was conducted with 50 Gy of X ray,tumor bed was irradiated with additional 10 Gy of electron beam,and supraclavicular field irradiation was also administered with 30 Gy of X ray and 22 Gy of electron beam. Results There was no recurrence during the follow up for 14 to 50 months.The acute side effects of radiotherapy included breast complaints(n=10,grade Ⅰ,23.26%),skin erythema and hyperpigmentation(n=19,grade Ⅰ,44.19%),moist desquamation(n=5,grade Ⅱ,11.63%) and radiation esophagitis(n=4,grade Ⅰ,9.30%),while one patient experienced radiation esophagitis one month after radiotherapy.No such complications as skin fibrosis and necrosis,angiotelectasis,breast and upper extremity edema occurred.The short-term cosmetic effects were satisfactory to 93.02% of all the patients. Conclusion For early stage of breast cancer(stage I and stage Ⅱ),breast-conserving operation combined with radiotherapy may yield satisfactory survival rate and short-term cosmetic effects,as well as low incidences of side effects.

In this paper, 29 endophytes were isolated from different organs and tissues of Lycium barbarum of Ningxia by tablet coating method, 18 of them was fungi, and 11 of them was actinomycetes. The endophytes quantity in the different tissues were leaves > flowers > roots >fruits; The hydroxyl radical scavenging activities of 11 endophytes were investigated by Fenton reaction, and total antioxidant capacities of them were examined by a. total antioxidant capacity test kit; culture features and strain-specific sequence analysis were employed to explore the diversity of the 11 endophytes. The result showed that 5 fungi and 6 actinomycetes that having antioxidant activity could be phylogenetically classified into 3 genera, 3 genera and 3 families, respectively. The total antioxidant capacity and hydroxyl radical scavenging activity of the 11 endophytes showed distinct difference. The antioxidant activity of Aspergillus were stronger, among which total antioxidant capacity of fL1 was (188.5 ± 0.549) U · mL⁻¹ and the IC₅₀ was 0.3 mg · L⁻¹; the IC₅₀ of strain fL1 was 0.42 mg · L⁻¹ and the total antioxidant capacity of fL9 was (113.63 ± 1.021) U · mL⁻¹, all of them were stronger than the positive control Vit C. The experimental results indicated that endophytic fungi of L. barbarum of Ningxia have a great developing and application prospect for the development of antioxidant agent.
