Objective:With the development of digital technology, network technology and mobile technology, new media aided-teaching has become a hot topic in medical teaching. However, the studies about the application of new media aided-teaching in training for professional postgraduates of neurosurgery are still less studied.Methods:In this study, 24 Batch 2015-2016 professional postgraduates of neurosurgery from Neurosurgery Department of Affiliated Hospital of Southwest Medical University were divided into the test group and control group, with 12 students in each group. From September 2016 to August 2018, students in the test group were taught with conventional teaching and various new media such as WeChat official accounts, professional video sharing websites and so on. The control group adopted conventional teaching methods. Students' theoretical knowledge, operation ability and clinical research ability were assessed between the two groups. SPSS 22.0 software was used for t test and descriptive statistics on the data.Results:The results of t test analysis showed that the scores of theoretical knowledge and general ability in test group were higher than those in control group, with significant differences ( P < 0.05). Meanwhile, the scores of teaching satisfaction, professional interest, teaching participation, knowledge mastery and scientific research ability in the test group were higher than those in the control group, with significant differences ( P<0.05). Conclusion:Conventional teaching combined with new media aided-teaching is a good new training model for professional postgraduates of neurosurgery, which has improved students' participation and motivation of study and contributed to the training of medical students' comprehensive abilities.

Objective To evaluate the efficacy of low-dose levothyroxine sodium in treatment of severe pulmonary tuberculosis with euthyroid sick syndrome(ESS). Methods One hundred and twenty inpatients with severe pulmonary tuberculosis and ESS were randomly divided into treatment group and control group by gender, age, disease duration and severity. Both groups were given anti- tuberculosis, antiinfection treatment and nutritional support for 2 weeks; patients in treatment group were given low-dose levothyroxine sodium additionally. Thyroid function, clinical improvements, increase of albumin, reduction of acid-fast bacilli, improvements on images and the mortality rates were compared between the groups.Results After 2 weeks of treatment, symptoms including fever, cough and night sweats were improved in both groups. Marked improvements were observed in 19 patients(31.7%)of treatment group and 8 patients (13.3%)of control group(χ2 = 5. 73, P ＜ 0.05). Clearance rate of acid-fast bacilli in treatment group was 25.0%(15/60), but that in the control was only 6.7%(4/60)(χ2 = 7. 50, P ＜ 0.01). Serum albumin in the treatment group was increased to(34.2 ±0.4)g/L after the treatment, and that in the control group was(29.1 ±0.6)g/L(t =2.42, P＜0.05). T3 and FT3 were significantly increased in both groups, but more significant difference was observed in the treatment group(t = 59. 42 and 50. 66, P ＜ 0. 01). No empty closed after treatment in both groups, but the effective rate in treatment group was significantly higher than that in the control group(93.3% vs. 76.7%, χ2 =6. 54, P＜0.05). Two patients in control group died(2/60, 3. 3%), while no death was reported in treatment group. Conclusions Low-dose levothyroxine sodium treatment is effective for ESS in patients with severe pulmonary tuberculosis.Improvement on low T3 syndrome may be an important indicator for the overall improvement or recovery.

ObjectiveTo explore the feasibility and safety of preoperative cardiac rehabilitation (CR) nursing intervention in patients with severe valvular disease, and to evaluate the effect of preoperative exercise-mediated cardiac rehabilitation nursing on the clinical outcomes of patients after operation. MethodsFrom January to December of 2017, 108 patients with advanced valvular heart disease (AVHD) admitted in Department of Cardiothoracic Surgery, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were selected based on the diagnostic standard for AVHD. The AVHD patients should not be younger than 18 years old, left ventricular ejection fraction(LVEF) less than 40%, and need repair of interventricular septal perforation, resection of ventricular aneurysm and radiofrequency ablation of surgical atrial fibrillation simultaneously. Random number method was used to divide the patients into control group and cardiac rehabilitation nursing intervention group (CR group). Mitral and aortic valve lesions were the main types of valvular lesions in the two groups, and the principles of preoperative treatment were the same. Patients in the control group received routine nursing after admission. The patients in the observation group were evaluated by 6 minute walking test (6MWT) after admission. According to the distance of 6MWT, MOTO Med nursing intervention was carried out in gradeⅠ andⅡ. Frequency was once a day, 30 minutes each time, the first movement resistance was 1 kg, and was adjusted appropriately according to the individual situation. Exercise training and aerobic training were carried out for gradeⅢ andⅣ, with emphasis on lower limb muscles, abdominal muscles and ectopectoralis once a day for 20 minutes each time. ResultsThere was no significant difference in hospital stay, ICU stay time and mechanical ventilation time between the two groups (P＞0.05). The LVEF value of CR group was significantly higher than that of control group at the early stage after operation [(42.5±6.2) vs .(31.0±4.5),P＜0.001)]. The 6 MWT (P=0.009) and self-management(Barthel) score (P=0.001) of CR group were better than those of control group. There was no significant difference in quality of life between the two groups 30 days after operation(P＞ 0.05). ConclusionsPreoperative cardiac rehabilitation nursing intervention can effectively improve the cardiac function of patients with severe valvular disease early after operation, increase the early exercise tolerance of patients after operation, improve the early self-care ability of patients after operation, and help patients recover better and faster.

Objective:To evaluate a new imaging sign, named" bilateral water sign" (BWS), which can evaluate the neurovascular compression of primary trigeminal neuralgia (TN).Methods:A prospective study was conducted on 85 primary TN patients admitted to our hospital from March 2017 to March 2019. All patients accepted magnetic resonance 3D-T2W-DRIVEN sequence examination and multiplanar reconstruction (MPR) for post-processing. The sequential nerve (low signal)-cerebrospinal fluid (high signal)-vessel (low signal)-cerebrospinal fluid (high signal)-nerve (low signal) signs on the recombination plane were named as "BWS". The sensitivity, specificity, positive predictive value and negative predictive value of BWS in evaluating the neurovascular compression were calculated respectively, by combining with intraoperative situation of microvascular decompression (MVD).Results:In 85 TN patients, 46 patients (54.12%) had BWS. The sensitivity was 57.14%, the specificity was 75.00%, the positive predictive value was 95.65% and the negative predictive value was 15.38%. There was a statistically significant difference in the degree of neurovascular compression between patients with and without BWS ( P<0.05); and degree of neurovascular compression was severer in patients with BWS. Conclusion:BWS can evaluate the relation of neurovascular compression in TN patients and suggest the degree of neurovascular compression.
