OBJECTIVE: To investigate the effectiveness of TiRobot-assisted minimally invasive treatment for fragility fractures of the pelvis (FFP) in elderly patients. METHODS: A retrospective analysis was conducted on the clinical data of 176 patients with FFP who were admitted between July 2018 and July 2024 and met the selection criteria. Among them, 95 patients underwent TiRobot-assisted closed reduction and minimally invasive cannulated screw fixation (robot group), while 81 patients underwent traditional open reduction and plate screw fixation (control group). There was no significant difference in baseline data such as gender, age, fracture classification, disease duration, and preoperative visual analogue scale (VAS) pain scores between the two groups ( P>0.05). The following parameters were recorded and compared between the two groups, including operation time, intraoperative blood loss, intraoperative transfusion rate, volume of intraoperative blood transfusion, maximum incision length, hospital stay, maximum residual displacement, reduction quality, fracture healing time, incidence of complications, VAS scores, Majeed pelvic function scores, and functional grading. RESULTS: All surgeries in both groups successfully completed. The robot group exhibited significantly shorter operation time, reduced intraoperative blood loss, lower intraoperative transfusion rate, smaller volume of intraoperative blood transfusion, shorter maximum incision length, and shorter hospital stay compared to the control group ( P<0.05). In the robot group, a total of 14 INFIX internal fixation frames and 280 cannulated screws were implanted, among which 250 screws were rated as excellent, 17 as good, and 13 as poor, resulting in a screw placement excellent and good rate of 95.36%. Radiological review revealed that the excellent and good rate of reduction quality was in 91.58% (87/95) in the robot group and 81.48% (66/81) in the control group, with no significant difference in postoperative maximum residual fracture displacement or reduction quality between the two groups (P>0.05). All patients in both groups were followed up 12-66 months, with an average of 28.9 months, and there was no significant difference in follow-up time between the two groups ( P>0.05). The fracture healing time in the robot group was significantly shorter than that in the control group ( P<0.05). At last follow-up, both groups showed significant improvement in VAS scores compared to preoperative values ( P<0.05); the change values of VAS scores, Majeed scores, and the excellent and good rate of Majeed pelvic function were significantly higher in the robot group than in the control group ( P<0.05). Regarding postoperative complications, there was no significant difference between the two groups in terms of gait changes, secondary surgeries, heterotopic ossification, incision infections, walking difficulties, internal fixation failure, or mortality rates ( P>0.05); however, the incidence of delayed wound healing was significantly lower in the robot group than in the control group ( P<0.05). CONCLUSION TiRobot-assisted minimally invasive treatment of elderly FFP is superior to traditional open reduction and internal fixation in terms of surgical trauma control, postoperative rehabilitation speed, and functional recovery.

Objective:To investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.

Objective:To establish an animal model of trans-sutural distraction osteogenesis in SD rats.Methods:A self-designed V-shaped distraction device(distractor)was fabricated with the traction force(N)of 0,1.3,2.2,3.0,4.3 and 5.0 corresponding to the distraction length(mm)of 5,4,3,2,1 and 0 respectively,meeting the trans-sutural distraction osteogenesis requirements in skull of 5-week-old SD rats.The distractor was plased into the sagittal suture of 12 SD rats.Continuous sampling was conducted 1,3,5 and 7 days respectively(n=3)after operation.The tissue changes in the trans-sutural distraction area were observed by HE and Masson's trichrome staining.Inflammation levels were determined using Arg-1 immunofluorescence staining.The early angiogenesis was clarified through co-staining with CD31 and EMCN.Results:A stable trans-sutural distraction osteogenesis model was estab-lished,5 mm distraction osteogenesis width was observed completely within 7 days of distraction.Significant new bone formation was observed at 7 days after operation.Arg-1 expression increased and was concentrated at the bone margins,overlapping with the areas of new bone formation.EMCN expression gradually decreased,and by day 7 CD31 was predominant,indicating the basic maturation of blood vessels.Conclusion:This study successfully constructed a stable and effective trans-sutural distraction osteogenesis animal model,and provides an experimental basis for the investigation of its early continuous histological changes.

Objective:To investigate the short-term efficacy of the intelligent robot-assisted fracture reduction system (RAFR) in the treatment of Tile-type C1-2 pelvic fractures.Methods:A retrospective study was conducted to analyze the clinical data of the 15 patients who had been treated for Tile-type C pelvic fractures at Department of Orthopedic Trauma, Foshan Hospital of Traditional Chinese Medicine between June 2022 and November 2023. The cohort were 7 males and 8 females, with an age of (51.6±22.1) years and a body mass index of (22.35±2.14) kg/m 2. According to the Tile classification, there were 9 cases of type C1 and 6 cases of type C2. The interval from injury to surgery was (11.3±3.9) days. Minimally invasive closed reduction and internal fixation of pelvic fractures were performed with the assistance of RAFR system. The anterior pelvic ring was fixed with percutaneous hollow screws from the pubic branch, and the posterior pelvic ring fixed with percutaneous hollow screws from the sacroiliac joint. If necessary, external fixation brackets and internal stent fixation technique for the anterior pelvic ring were used to enhance the stability of the pelvic ring. The frequency and time of intraoperative fluoroscopy, reduction time, surgical time, intraoperative bleeding volume, fracture reduction quality, follow-up time, fracture healing time, pelvic function recovery at the last follow-up, and incidence of complications were recorded. Results:With the assistance of RAFR system, 15 patients were all successfully treated with minimally invasive closed reduction and internal fixation for pelvic fractures. For this cohort, intraoperative fluoroscopy frequency was 31 (20, 55) times, fluoroscopy time 25.8 (18.0, 33.0) seconds, reduction time (57.7±3.5) minutes, surgical time 205 (200, 210) minutes, intraoperative bleeding volume 100 (100, 200) mL, and residual displacement (7.55±3.51) mm. According to the Matta scoring, the postoperative quality of fracture reduction was evaluated as excellent in 4 cases, as good in 8 cases, and as fair in 3 cases. Fourteen patients were followed up for 15.0 (10.8, 18.0) months after surgery, and 1 patient was lost to the follow-up. The fracture healing time for the 14 patients was 3.6 (3.2, 4.7) months. The Majeed functional score at the last follow-up was (83.4±6.4) points, giving 4 excellent and 10 good cases.Conclusion:The RAFR system can facilitate precise and minimally invasive closed reduction for the majority of patients with Tile-type C1-2 pelvic fracture, achieving satisfactory fracture reduction quality and short-term efficacy.

Remote pharmaceutical care refers to the process that pharmacists provide pharmaceutical care to patients remotely through information technology. Remote pharmaceutical care in China starts late and develops slowly. Therefore ，this paper discusses the pharmaceutical care modes that pharmacists at home and abroad can provide under the remote mode by collecting literature. The results show that foreign remote pharmaceutical care starts early and is relatively mature. The service mainly included remote follow-up and intervention ，24-hour online prescription and order review ，24-hour online drug reorganization ，and guidance on rational drug use in remote areas or community hospitals. The service population covers patients with cardiovascular disease ， diabetes，asthma，AIDS and so on. Some hospitals have established an integrated pharmaceutical care system of “Internet+Medical Consortium”in China ，with which pharmacists can provide patients with pharmaceutical care such as remote follow-up and intervention，drug consultation and so on. With the promotion of telemedicine ，domestic pharmacists can gradually expand the scope of services ，expand pharmaceutical services such as remote consultation and remote popular science push ，and realize the sharing of high-quality pharmaceutical care for the whole people.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
