ABSTRACT

Objective To investigate the effect of autologous peripheral blood stem cell transplanta-tion combined with CD34 + cells and oral sarpogrelate hydrochloride for the treatment of vascular reconstruc-tion and blood supply on the thromboangiitis obliterans. Methods Thromboangiitis obliterans ( TAO) of 262 patients with 262 lower limbs were divided into stem cells CD34 + cells transplantation combined with sarpogrelate hydrochloride group ( group A) with 100 lower limbs, CD34 + stem cell transplantation group ( group B) with 91 lower limbs, and sarpogrelate hydrochloride oral group ( group C) with 71 lower limbs. The degree of lower limb local blood flow variability were calculated at the three levels of skin, blood vessels and blood by preoperative and postoperative use of multi-function monitoring instrument, Doppler detector, transcutaneous oxygen pressure monitor, and digital subtraction angiography ( DSA) , respectively. Results⑴ The degree of shank, foot cyanosis, cool skin, and pain was relieved significantly in groups A and B than in group C for 1 month after the treatment (P<0. 05). ⑵Intermittent claudication distance, the skin temperature of the lower leg and foot to patients in the groups A and B than in group C, with a significant difference (F=7. 01, F=7. 04, P<0. 05) for 3 months after the treatment. ⑶ Among the patients with amputation, 10 cases were in group A, 16 cases in group B, and 31 cases in group C for 6 months after the treatment. ⑷ Transcutaneous oxygen pressure was increased from ( 30. 43 ± 4. 31 ) mmHg to ( 37. 21 ± 9. 01)mmHg (F=5. 69, P<0. 05), ankle brachial index from (0. 32 ±0. 23) to (0. 91 ± 0. 16) (F=6. 71, P<0. 05), the volume of blood flow index from the photoelectric (0. 22 ± 0. 04) to (0. 83 ± 0. 13 (F=5. 69, P<0. 05), oxygen saturation from (42. 41 ±9. 61)% to (79. 61 ±20. 34)% (F=5. 74, P<0. 05), and DSA score (0. 23 ± 0. 03) increased to (1. 35 ± 0. 23) (F=7. 14, P<0. 05), which was sig-nificantly higher than group B and group C ( F=7. 01, F=7. 04, F=7. 12, F=7. 08, F=7. 15, P<0. 05) for one year after treatment. Conclusions Treatment of peripheral blood stem cells CD34 + cell transplantation combined with oral sarpogrelate hydrochloride can significantly improve the vascular regener-ation and its blood supply in TAO lower extremity limb.

ABSTRACT

Objective In a large-scale clinical medical examination, A2 type best multiple-choice test questions to the same knowledge were used respectively in simple and complex form, to compare the difficulty and discrimination indices of the two forms of test questions and provide evidence to the improve-ment of clinical medical examination. Method In a large-scale clinical medical examination more than 4000 candidates participated, and 20 questions to different knowledge points were randomly selected and used in the examination respectively in simple and complex A2 type best multiple-choice test questions. The difficulty and discrimination indices of the two forms of test questions were compared. Results The average difficulty coefficient of the 20 simple test questions (65.5 words per question in average) is 0.6829, and the average discriminative powers are 0.2675 and 0.2579 respectively using identification index method and point biserial correlation method. The average difficulty coefficient of the 20 complex test ques-tions (135.5 words per question in average) is 0.7095, and the average discriminative powers are 0.3065 and 0.2967 respectively using identification index method and point biserial correlation method. Conclusion To the same knowledge points, the average difficulty of complex A2 type best multiple-choice test questions is slightly lower than the simple ones, while the average discriminative power is increased in the complex questions. The complex A2 type test questions are of higher quality and more in line with the requirements of the medical entrance examination, medical education and examination reform.

ABSTRACT

The Chinese clinical medical national licensing examination is the profession ad-mittance exam, which is undertake the responsibility of selecting qualified physicians. It also promotes the medical education in China. The standard for examination, the examination content, methods for measuring the Chinese clinical medical national licensing examination as well as the reform and de-velopment, has a certaln guiding role to China's medical education and medical education reform. While reviewing the medical students' performance in the examination, we can discover the weakness in medical education, which is then conducive to the promotion of teaching reform and innovation. The competence based medical licensing examination reform in China, advocating the cultivation of clinical comprehensive ability as the core content to tralning and evaluating, is conducive to continuously im-proving the quality of medical education in China, and to tralning more qualified physicians in the country.
