ObjectiveTo compare the efficacies between heat-sensitive moxibustion and warm needling in treating cervical spondylosis of vertebroarterial type.MethodTotally 120 patients with cervical spondylosis of vertebroarterial type were randomized into a heat-sensitive moxibustion group and a warm needling group, 60 in each group. In addition to acupuncture at bilateral Fengchi (GB20), Wangu (GB12), Tianzhu (BL10), Dazhui (GV14) and Baihui (GV20), the heat-sensitive moxibustion group was given mild moxibustion to the heat-sensitive points in cervical and scapular regions, while the warm needling group was given regular moxibustion.ResultGenerally, after 20 treatment sessions, efficacy wasfound in both groups, and there were significant differences in both groups after intervention (P<0.05), while the improvements of integral score, dizziness, cervical and shoulder pain, and the recovery and markedly-effective rate in the heat-sensitive moxibustion group were significantlysuperiorto that in the warm needling group (P<0.05).ConclusionCompared to warm needling treatment, heat-sensitive moxibustion can more significantly improve dizziness and pain in patients with cervical spondylosis of vertebroarterial type, and thus enhance the therapeutic efficacy.

Objective Analysis of MRI image of lateral ventricular subependymomas to improve our recognition of radiology manifestation of the disease. Methods Clinical data and MRI findings of 6 patients with subependymomas proved by surgical pathology, observed from January 2007 to June 2013, were analyzed retrospectively. Results Six patients (4 males and 2 females) presented with headache and dizziness. Among these 6 patients, tumor developed in right lateral ventri-cle in three patients, in left lateral ventricle in 2 patients and in frontal of dual lateral ventricle in one patient. In MRI image, tumors showed iso-intense to hypointense to normal white matter on T1-weighted and DWI images, hyperintense on T2-weighted and FLAIR. Mild or no enhancement was noted in most cases. MRS showed findings consistent with low-grade tu-mor, with a normal choline peak and depressed N-acetyl-aspartate peak. Conclusion Lateral ventricular subependymo-mas have characteristic MRI features and multi-direction images are helpful for diagnosis.

Purpose To analysis the CT manifestations of acinar cell carcinomas of the pancreas (ACCs) in order to know more about its CT signs. Materials and Methods The plain and enhanced CT findings of 9 patients with AACs proved pathologically were analyzed retrospectively. Results The main image ifndings of the patients were as follows:①the pancreas grew with exophytic dilatability;②they tended to be large (average diameter was 4.7 cm), with round or oval shape; ③ the lesions showed hypodense on enhanced scan and the solid areas showed slight enhancement in the arterial phase compared with normal pancreas;④most lesions had uniform or partial thin enhanced ring;⑤most lesions demonstrated cystic or necrotic;⑥few had pancreatic/biliary ductal dilatation and peripancreatic involvement;⑦few showed internal calciifcation or intratumoral hemorrhage. Conclusion Plain CT scan and enhanced scan are signiifcant in locating and differentiating acinar cell carcinoma of the pancreas.

In order to improve the clinical skills of medical students,the First Clinical School of Tongji Medical College,Huazhong University of Science and Technology strengthened the construction of teaching base,teaching materials,teaching team,curriculum and assessment methods,and established a comprehensive experimental teaching system of clinical skills.

Objective To evaluate the application value of high resolution MRI fat suppression T2WI combined with DWI in anal fistula and its activity. Methods We analyzed the clinical data and MRI findings of 59 patients who received high resolution MRI from January 2016 to November 2017. According to the clinical and surgical results,anal fistulas were divided into positive inflammatory activity(PIA)and negative inflammatory activity(NIA). ADC values of anal fistula were measured and the optimal cut-off of ADC values were calculated. Results 59 patients with 71 anal fistulas and 62 internal openings confirmed by surgical results.ADC values were differenct between PIA and NIA anal fistulas(P = 0.001) and the optimal cut-off of ADC value were 1.214. The sensitivity of high resolution MRI fat suppression T2WI,DWI and T2WI combined with DWI for detecting anal fistula and internal opening were 80.28%(57/71),83.10%(59/71),95.77%(68/71) and 82.26%(51/62), 83.87%(52/62),96.77%(60/62),respectively. Conclusion MRI-DWI is very important for evaluating the activities of anal fistula and thigh resolution MRI fat suppression T2WI combined with DWI has the highest sensitivity for detecting anal fistula and internal opening.

Objective:To understand the results of blind evaluation of dissertation of three-year doctors and eight-year medical doctors, and to explore the improvement measures of eight-year program education.Methods:The data analysis method was manipulated. A total of 47 eight-year doctoral and 88 three-year doctoral dissertations submitted by the first clinical college of Huazhong University of Science and Technology in 2020 were selected as the research material. SPSS 17.0 was used to perform Chi-square test to compare the itemized evaluation opinions of the dissertation, Spearman test was used to analyze the correlation between the defense opinions, itemized evaluation opinions and the overall evaluation.Results:The gap between eight-year and three-year doctoral dissertation is mainly manifested in innovation and research value ( χ2=9.10, P=0.003), topic and review ( χ2=5.70, P=0.017), while there is no significant difference in the overall assessment and oral defense suggestion. The main influencing factor of dissertation defense suggestion for both doctors was the dissertation standardization (eight-year: r s=0.53, P<0.001; three-year: r s=0.45, P<0.001). The evaluation results of eight-year doctor dissertation were closely related to basic knowledge and scientific research ability ( r s=0.74, P<0.001). Conclusion:There is no significant difference between eight-year doctors and full-time doctors in research attitude. But there was a certain gap in scientific research and innovation ability among them. It is suggested to clarify the teaching objectives, formulate and refine the evaluation system of dissertations, and strengthen the cultivation of scientific research interest and academic belief of eight-year study program.
