OBJECTIVE To provide ideas for clinical diagnosis， treatment and pharmaceutical care of rhino-orbito-cerebral mucormycosis （ROCM）. METHODS The diagnosis and treatment of 1 case of ROCM in which clinical pharmacists participated were analyzed. Combined with treatment guidelines， the actual situation of drug accessibility and economy， clinical pharmacists recommend amphotericin B colloidal dispersion in combination with posaconazole to treat fungal infections. The clinical efficacy， liver and kidney function and electrolytes were monitored. To increase the local concentration of amphotericin B deoxycholate （AmB-D）， clinical pharmacists assisted physicians in determining the dosage and formulation of AmB-D for intrathecal injection， intranasal and eye drops based on the results of blood and cerebrospinal fluid examinations. In response to the situation that the plasma trough concentration of posaconazole had not reached the target， clinical pharmacists recommended that Posaconazole oral suspension was replaced with Posaconazole enteric-coated tablets， and provided the patient with therapeutic drug monitoring （TDM）， individualized medication guidance， and long-term follow-up after discharge. RESULTS The clinician adopted the advice of the clinical pharmacists. After treatment， the patient was discharged from the hospital with medicine after her condition improved. CONCLUSIONS Clinical pharmacists develop individualized treatment protocols for ROCM patients by adjusting dose and dosage forms， providing medication monitoring and TDM to ensure the safety of drug use for patients.

With the development of imaging technology, advancements in surgical techniques, application of multidrug chemotherapy, and collaboration in postoperative rehabilitation, the local recurrence rate and survival of patients with osteosarcoma after limb-sparing surgery are comparable to those of patients after amputation. The area around the knee joint, including the distal portion of the femur and the proximal portion of the tibia, is a typical site of involvement for osteosarcoma. Metal prosthetic replacement is the most common method to reconstruct bone defect after tumor resection, which provides rapid recovery of limb function after surgery. This article mainly discusses the clinical challenge of limb-saving technology for pediatric osteosarcoma. It also describes how to optimally preserve the growth potential of children’s affected limbs to reduce the future limb length discrepancy. Limb-sparing technology is one of the most cutting-edge precision medical technologies in the industry. Sacrificing or preserving the knee joint according to the distance between the tumor of distal femur and the epiphyseal growth plate, retaining the potential for limb growth, 3D-printed reconstructed prostheses are becoming increasingly popular. This article summarizes the progress and future development in the surgical treatment of pediatric osteosarcoma around the knee to offer insights for orthopedic treatment of this disease.

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.

Objective:To explore the effect and value of the active learning mode based on mind mapping in the teaching of medical service support for major disasters.Methods:A total of 90 undergraduate students of 2016 Clinical Medicine of Naval Medical University were randomly selected as research objects, and they were randomly divided into observation group and control group. The 45 students in the control group used the traditional teaching mode, and the 45 students in the observation group used the mind mapping-based active learning mode for major disaster rescue and medical survice. The teaching time of the two groups was 12 h. The theoretical examination of knowledge and practical skills of the two groups of students were compared after teaching, and the students' satisfaction with the application of mind mapping-based teaching model in the teaching of medical service support for major disaster rescue was investigated. EmpowerStats and R softwares were used for t test and Chi-square test. Results:There were 24 males and 21 females in the observation group, with an average age of (21.40±0.69) years old. There were 22 males and 23 females, with an average age of (21.71±0.55) years old. The theoretical performance of the observation group (91.38±4.37) was significantly higher than that of the control group (84.91±3.98) ( P<0.001), and the practical skill performance of the observation group (92.98±3.24) was significantly higher than that of the control group (87.38±3.80) ( P<0.001). At the same time, the students' satisfaction with teaching effect in the observation group was 82.2% (37/45), which was significantly higher than that in the control group (37.8%, 17/45). Conclusion:The active learning mode based on mind mapping focuses on cultivating students' independent learning, interactive exploration and clinical thinking ability, and has a broad application prospect in the teaching of medical service support for major disasters.

Objective:To evaluate the clinical outcome of a special physeal sparing knee prosthesis for pediatric distal femoral osteosarcoma regarding the functional outcome, retention of the growth potential of the proximal tibia, and postoperative complications.Methods:A retrospective study was conducted to review 37 pediatric patients with osteosarcoma of distal femur who were treated in a single musculuskeletal tumor center between August 2015 and January 2019. Among them, 21 were boys and 16 were girls, aged from 5 to 12 years at the time of operation, with an average age of 9.1±2.1 years and the height of 115 to 160 cm, with an average of 140±10 cm. Tumor resection of distal femur was performed and the bone defect was reconstructed by a special hinged knee prosthesis which can preserve the proximal tibial epiphyseal plate. Demographic data was recorded. Overall leg length and tibial length was assessed by full-length standing anteroposterior radiographs of bilateral lower extremity with the patella pointing anteriorly preoperativelly and postoperativelly at each follow up. And the growth potential of the affected proximal tibia was calculated by comparing with the preoperative length of tibia. Meanwhile, the functional outcome was assessed by using the Musculoskeletal Tumor Society (MSTS) system, and the postoperative complications were analysed.Results:All patients underwent the tumor resection and reconstruction operation successfully. The average operation duration was 143±41 minutes, ranging 90 to 250 minutes. The average intraoperative blood loss was 314±397 ml, ranging 30 to 2 200 ml. The patients were followed up for 24 to 64 months, averaging 42.3±12.1 months. The postoperative knee range of motion was 100-130 degrees, with an average of 115.6±7.2 degrees. The postoperative MSTS score was 23-30, with an average of 26.7±1.6. To the last follow-up, the limb length discrepancy of the lower limb was 1.3 to 10 cm, and the length of the tibia was shortened from 0 to 3.8 cm compared with the opposite side, with an average of 1.3±1.0 cm. The growth percentage of the proximal tibial epiphysis on the affected side was 30% to 100%, with an average of 70%±17%. Totally, 13 patients suffered postoperative complication, the overall incidence of complications was 35% (13/37), and prosthesis-related complications were 16% (6/37). Three patients with wound dehiscence were managed by debridement and antibiotics. Radiographs revealed femoral stem loosening in a single patient 3 years after the initial operation and then the prosthesis was converted to an adult tumor knee endoprosthesis. Two cases experienced breakage of the femoral stem at 30 and 33 months, respectively, due to an accidental injury. They received revision surgery, and a new femoral prosthesis component was replaced. One patient developed femoral stem breakage at 10 months after surgery due to fatigue fracture, which treated with revision surgery. Tumor recurrence occurred in 6 patients. Among them, tumor recurrence in soft tissue occurred in 4 patients, and treated with regional resection without further recurrence. The other 2 patients experienced tumor recurrence at the distal femoral site, and treated with resection and prosthetic revision.Conclusion:The physeal sparing pediatric knee prosthesis can preserve the growth potential of the proximal tibial epiphyseal plate with good postoperative function and low incidence of prosthesis complications. Therefore, it can be an alternativeespecially for skeletally immature patients with distal femur osteosarcoma.

ObjectiveTo explore the effects of different intensity of wearable lower limb rehabilitation robot-assisted training on walking function, lower limb motor function, balance function and functional independence of stroke patients. MethodsFrom November, 2021 to December, 2022, 60 stroke patients hospitalized in Beijing Bo'ai Hospital were randomly divided into control group (n = 20), observation group 1 (n = 20) and observation group 2 (n = 20). All the groups received routine rehabilitation, while the control group received routine walking training 30 minutes a day, the observation group 1 received wearable lower limb rehabilitation robot-assisted training 30 minutes a day, and the observation group 2 received wearable lower limb rehabilitation robot-assisted training 60 minutes a day, for four weeks. They were assessed with Functional Ambulation Category scale (FAC), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Berg Balance Scale (BBS) and Rivermead Mobility Index (RMI) before and after treatment. ResultsOne case in the observation group 1 and three cases in the observation group 2 dropped down. The FAC, FMA-LE, BBS and RMI scores improved in all the three groups after treatment (|Z| > 3.448, |t| > 8.102, P < 0.001), and there was no significant difference in all the indexes among the three groups (|H| < 4.643, F = 1.454, P > 0.05); however, the improvement of BBS score was more in the observation group 1 than in the control group (P < 0.05), and the improvement of all the indexes was more in the observation group 2 than in the control group (P < 0.05). ConclusionThe wearable lower limb rehabilitation robot-assisted training may promote the recovery of walking function, lower limb motor function, balance function and functional independence of stroke patients, and high-intensity training seems to be more effective.

Objective:To investigate the efficacy of 3D-printed segmental tumor prosthesis for reconstruction of bone defects after resection of weight-bearing long bone tumors in the lower extremity.Methods:A total of 71 patients who received 3D-printed segmental metal tumor prosthesis for reconstruction of bone defects from August 2015 to August 2021 at the Musculoskeletal Tumor Center of Peking University People's Hospital were retrospectively analyzed. There were 40 males and 31 females, aged 23.08±18.52 years (range, 10-63 years). Tumor types: 49 cases of osteosarcoma, 9 cases of Ewing sarcoma, 3 cases of chondrosarcoma, 3 cases of synovial sarcoma, 2 cases of pleomorphic undifferentiated sarcoma, 2 cases of rhabdomyosarcoma, 2 cases of bone metastasis, and 1 case of low-grade malignant tumor of mesenchymal origin. Ennecking stage of bone tumor: 19 cases of stage III, 52 cases of stage IIb. Tumor location: femur 43 cases, tibia 28 cases. Operative time, intraoperative bleeding, patient survival and postoperative complications were recorded. Kaplan-Meier curves for prosthetic survival were plotted. The osseointegration at the prothesis-bone interface was determined by combination of clinical presentation and imaging. Limb function scores were evaluated using the Musculoskeletal Tumor Society (MSTS) 93 function score.Results:All 71 patients successfully completed the operation and were followed up for 24.4±13.2 months (range, 6.6-65.4 months). At the last follow-up, 50 patients survived without disease, 12 survived with the disease, and the remaining 9 cases died with disease. A total of 11 cases showed prosthesis failure, including 1 case of aseptic loosening, 3 cases of screw breakage or periprosthetic fracture, 1 case of periprosthetic infection, and 6 cases of tumor progression involving the prosthesis. The Kaplan-Meier curve showed that the 1-year, 3-year and 5-year survival rates of prosthesis were 94.2%±2.8%, 86.1%±4.7% and 79.5%±9.2%, respectively. 62 patients received functional follow-up, and the MSTS93 functional score at the last follow-up was 23.95±5.03 points (range, 10-30 points), with an excellent rate of 90% (56/62). The score of femoral prosthesis was 24.63±4.97 points (range, 13-30 points) and the score of tibial prosthesis was 23.29±5.09 points (range, 10-29).Conclusion:3D-printed segmental tumor prosthesis for reconstruction of bone defect after resection of weight-bearing long bone tumors in the lower extremity has a relative high survival rate, a low incidence of prosthetic complications, and a good recovery of function, and it can be used as an option for the postoperative reconstruction of bone tumors in weight-bearing bones of the lower extremity.
