Objective To evaluate the efficacy and safety of 3D printing patient-specific external guide template in assisting minimally invasive screwing for treatment of pelvic and acetabular fractures.Methods The clinical and follow-up data of 39 pelvic or acetabular fractures were retrospectively analyzed which had been treated from June 2016 to February 2018 at Department of Orthopaedics,Wuhan Union Hospital.The patients were divided into a template group and a freehand group.In the template group,there were 14 men and 7 women with an age of 46.3 ± 18.2 years and 17 pelvic fractures and 4 acetabular fractures;in the freehand group,there were 12 men and 6 women with an age of 43.8 ± 12.2 years and 14 pelvic fractures and 4 acetabular fractures.The 2 groups were compared in terms of operation time,fluoroscopic frequency,guide wire adjustments,fracture reduction,screw penetration rate,function evaluation and adverse events.Results All the 39 patients were followed up for 9 to 13 months (average,11.6 months).A total of 42 screws were placed in the template group and 35 screws in the freehand group.The values of operation time (43.8 ± 22.2 min),fluoroscopic frequency (29.6 ± 10.7 times) and guide wire adjustments (1.8 ± 1.2 times) in the external guide template group were all significantly lower than those in the freehand group (73.8 ±22.6 min,54.6 ± 16.5 times and 9.8 ±2.8 times,respectively) (P ＜0.05).There were no significant differences between the 2 groups in screw penetration rate,rate of satisfactory reduction,Majeed scores for pelvic function or modified Merle d'Aubigné scores at the last follow-ups (P ＞ 0.05).One case in the freehand group experienced numbness after operation on unilateral dorsi pedis which disappeared at 3-month follow-up.Conclusion The 3D printing patient-specific external guide template can reduce fluoroscopic frequency,save operation time and improve accuracy of screw insertion,providing a new means for minimally invasive treatment of pelvis and acetabular fractures.

Objective:To explore the value of panoramic teaching in clinical practice teaching of department of respiratory medicine.Methods:A total of 35 clinical interns who had a 3-week rotation in the department of respiratory medicine from October 2019 to June 2020 were selected, and they were divided into a control group ( n=17) and a study group ( n=18) according to the order of admission. The control group used traditional teaching, and the research group used panoramic teaching. After the teaching, the teaching effect was evaluated through theoretical knowledge assessment, practical assessment and questionnaire survey. SPSS 19.0 was used for t test. Results:There was no statistically significant difference between the two groups of interns in theoretical assessment [(89.62±4.05) points vs. (90.84±4.12) points, t=-0.891, P=0.379]. The results of practice assessment (case analysis, physical examination of the department, medical history inquiry and skills manipulation) of the study group were significantly higher than those of the control group ( P<0.05). The interns in study group were better than those in control group in such aspects as learning interest, self-learning ability, self-study ability, doctor-patient communication language expression ability, literature review ability, clinical thinking ability, comprehensive analysis ability, knowledge development ability, system diagnosis ability, teamwork ability and teaching satisfaction ( P<0.05). Conclusion:Panoramic teaching can effectively improve the ability of interns to master the clinical diagnosis and treatment of respiratory medicine, improve the teaching effect, and improve the learning ability and clinical competence of interns in the future.

Objective:To investigate the advantages and disadvantages and clinical effects of integrated acetabular quadrilateral surface buttress plate in the treatment of acetabular both column fractures.Methods:From September 2017 to March 2019, 14 patients with acetabular both column fractures were treated with integrated quadrilateral acetabular buttress plate and were followed up. The clinical data were retrospectively analyzed. There were 10 males and 4 females with an average age of 53.2 years (range, 26-75 years). Fracture classification were both column fractures according to the Letournel-Judet classification system, including 11 cases of combined posterior wall without posterior dislocation. The time from injury to operation was 8-19 days, with an average of 10.3 days. All operations were performed with a supra-ilioinguinal approach. After satisfactory reduction, the integrated acetabular quadrilateral surface buttress plate was used to fix the anterior and posterior column and quadrilateral fractures at the same time. After operation, Matta criteria was used to evaluate the quality of fracture reduction on postoperative images, and modified Merle d'Aubigné-Postel score to evaluate hip joint function.Results:The average operation time was 180 min (range, 120-320 min), and the intraoperative average blood loss was 980 ml (range, 700-1 600 ml). Operations were performed successfully with none intraoperative reshaping conducted, and the plate could fit into the bone surface well. All 14 patients were followed up with an average of 15.6 months (range, 9-20 months). During the follow-up, all fractures healed with an average of 3 months (range, 2.5-5 months). The reduction quality evaluated by the Matta criteria were 7 anatomical, 5 satisfactory, and 2 unsatisfactory, with an excellent and good rate of 85.7% (12/14). The hip joint function at the last follow-up was in accordance with the modified Merle d'Aubigné-Postel score was 12-18 points, with an average of 16.9 points, of which 8 excellent, 4 good, and 2 fair. The excellent and good function rate was 85.7% (12/14). During the operation, 1 patient had a rupture of about 1 cm of the peritoneum during the separation of the spermatic cord, which was immediately sutured and repaired. One patient had obturator nerve paralysis after the operation, without special treatment, and the paralysis symptoms were relieved during the 6th-month follow-up. There were no other operation-related complications.Conclusion:For both-column fractures characterized by central dislocation of the femoral head, the integrated acetabular quadrilateral buttress plate can simultaneously fix the anterior and posterior columns and quadrilateral surface at the same time. Satisfactory reduction and functional outcomes could be achieved by the novel plates.

Acute kidney injury （AKI） is a clinical syndrome characterized by a rapid decline in renal function over a short period due to various etiologic factors. If left untreated， AKI can progress to chronic kidney disease （CKD） or even end-stage renal disease （ESRD）. Although continuous renal replacement therapy （CRRT） can manage severe AKI， effective pharmacological treatments for AKI remain largely unavailable. Chinese medicine， with its multi-target and multi-pathway approaches， has accumulated substantial theoretical and practical knowledge in treating AKI and related complications. Rehmanniae Radix is a commonly used Chinese medicinal， known for its functions in clearing heat， cooling blood， nourishing yin， and promoting fluid production. The primary active ingredients of Rehmanniae Radix include catalpol， acteoside， and aucubin. In this study， we summarized recent research on the effect of the active ingredients of Rehmanniae Radix in preventing and treating AKI. We found that the key mechanisms underlying its anti-AKI effects include amelioration of inflammation， alleviation of oxidative stress， and inhibition of apoptosis. Additionally， the antifibrotic properties of the active ingredients of Rehmanniae Radix suggest its potential in slowing CKD progression. We reviewed the mechanisms of Rehmanniae Radix in treating AKI and its antifibrotic effects to provide a scientific basis for developing new AKI drugs， promoting the utilization of Rehmanniae Radix resources， and reducing the transition from AKI to CKD.
