OBJECTIVE To establish the method for the content determination of ephedrine hydrochloride and pseudoephedrine hydrochloride in Shexiang zhuanggu plaster ，and to evaluate the quality of 222 batches of Shexiang zhuanggu plaster from 41 manufacturers. METHODS HPLC method was established. The determination was performed on Shimadzu Shim-pack GIS-C 18 column with mobile phase consisted of acetonitrile- 0.1％ phosphoric acid （3∶97，V/V）at the flow rate of 0.9 mL/min. The column temperature was set at 30 ℃，the detection wavelength was 210 nm，the sample size was 10 μL. Taking the content data of 222 batches of samples as index ，the cluster heatmap was drawn by Hiplot biomedical data visualization and analysis platform. RESULTS The results of the methodological investigation were in line with the requirements of the general principles stated in 2020 edition of Chinese Pharmacopoeia （part Ⅳ ）. The total contents of ephedrine hydrochloride and pseudoephedrine hydrochloride in 222 batches of samples from 41 manufacturers were 0.646-6.325 μg/cm2. Results of cluster heatmap analysis showed that these samples of 41 manufacturers could be divided into 3 categories. The contents of components in samples from different manufacturers varied greatly ，and the contents of components in different batches of samples from the same manufacturers also varied greatly. If the proposed limit of this product was that the total amount of ephedrine hydrochloride and pseudoephedrine hydrochloride per 1 cm2 would not be less than 1.00 μg，23 of the 222 batches of samples were unqualified. CONCLUSIONS The established method for the content determination of ephedrine hydrochloride and pseudoephedrine hydrochloride in Shexiang zhuanggu plaster is accurate and precise ，and can be used for the quality control. Some manufacturers should pay attention to optimizing production process and strengthening quality control.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Objective:To evaluate the hip C-arm fluoroscopy at primary position in internal fixation of femoral neck fracture.Methods:A retrospective study was conducted of the 69 patients with femoral neck fracture who had been treated from August 2015 to August 2018.They were divided into a primary position group ( n=35) subjected to C-arm hip fluoroscopy at primary position under symmetry traction of bilateral lower limbs for reduction of femoral neck fracture and a control group ( n=34) subjected to C-arm hip fluoroscopy at frog’s position on the healthy side for traction and reduction of the injured hip. The 2 groups were compared in terms of fluoroscopy frequency, times of resetting guide pin, intraoperative blood loss and total operation time. Results:The 2 groups were comparable due to insignificant significances between them in the preoperative general data like gender, age, fracture type, injury cause, or interval from injury to operation ( P>0.05). Compared with the control group, the primary position group showed less intraoperative fluoroscopy (7.2 times ± 0.5 times versus 16.1 times ± 1.2 times), fewer times of resetting guide pin (2.1 times ± 0.31 times versus 4.7 times ± 0.8 times), less intraoperative blood loss (96.8 mL ± 18.6 mL versus 198.1 mL ± 13.2 mL), and shorter total operation time (1.2 h ± 0.2 h versus 1.6 h ± 0.3 h). All the differences were statistically significant ( P<0.05). Conclusions:C-arm hip fluoroscopy at primary position may protect the stability after fracture reduction because bilateral lower limbs are under symmetrical traction and the hip position needs no alteration. Operation of C-arm fluoroscopy is easy and convenient and produces clear images. Therefore, this new mode of fluoroscopy has advantages of less intraoperative fluoroscopy and guide pin resetting, leading to significantly reduced intraoperative blood loss, ineffective operation time and anesthesia time.
