ABSTRACT
Objective To investigate the value of 3D printing technology practical training applied in practical teaching of graduate students of otorhinolaryngology.Methods Total 42 graduate students of otorhinolaryngology were divided into control group (20) and experimental group (22) randomly.The control group received traditional teaching mode while the experimental group received 3D printing technology practical training mode.The effect of teaching modes was evaluated by questionnaire and theoretical and practical examinations.The data were analyzed through t test of SPSS 17.0.Result Questionnaire survey of the different teaching modes showed that:the average score of control group was (59.4 ± 3.5),while that of experimental group was (64.6 ± 3.6).Theoretical examination score showed that:the average score of control group was (75.7 ± 5.1),while that of experimental group was (81.5±7.7).Practical examination score showed that:the average score of control group was (74.5 ± 5.8),while that of experimental group was (80.9 ± 6.9).All the differences are statistically significant (P＜0.05).Conclusion The recognition degree of 3D printing technology practical training in these graduate students was significantly higher than that of the traditional teaching mode,and the teaching effect from 3D printing technology practical training was better compared with that from the traditional teaching mode.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the efficacy among acupuncture based on "jin" theory, regular acupuncture and western medication.</p><p><b>METHODS</b>A total of 95 cases, by using incomplete randomization method, were divided into a "jin" theory acupuncture group (32 cases), a regular acupuncture group (31 cases) and a medication group (32 cases). Patients in the "jin" theory acupuncture group were treated with acupuncture based on "jin" theory which included the "gather" and "knot" points on the affected side: positive reacted points, Fengchi (GB 20), Tianrong (SI 17), Tianyou (TE16) and Yiming (EX-HN14) as the main acupoints, while the Ermen (TE 21), Tinggong (SI 19) and Tinghui (GB 2) and zhigou (TE 6) as the auxiliary acpoints; the treatment was given once a day. Patients in the regular acupuncture group were treated with regular acupuncture at Tinggong (SI 19), Tin- ghui (GB 2) and Ermen (TE 21) and other matched acupoints based on syndrome differentiation, once a day. Pa- tients in the medication group were treated with oral administration of betahistine mesylate, three times a day. Ten days of treatment were taken as one session in three groups, and totally 2 sessions were given. Visual analogue scale (VAS), tinnitus handicap inventory (THD), and tinnitus severity assessment scale (TSIS) were evaluated before and after treatment; also the clinical efficacy was compared among three groups.</p><p><b>RESULTS</b>There are 5 drop-out cases du- ring the study. After the treatment, the VAS, THI and TSIS were improved in three groups (all P < 0.05); the VAS, THI and TSIS in the "jin" theory acupuncture group were lower than those in the regular acupuncture group and medication group (P < 0.05, P < 0.01). The total effective rate was 90.0% (27/30), 80.0% (24/30) and 63.3% (19/30), which was higher in the "jin" theory acupuncture group (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>The acupuncture based on "jin" theory is superior to regular acupuncture and western medication for cervical tinnitus.</p>
