Objective:To investigate the difference in intracranial infection rate between long-tunneled external ventricular drainage(LTEVD)and conventional external ventricular drainage(EVD),as well as the risk factors for intracranial infection.Methods:A retro-spective analysis was performed for the clinical data of 45 patients who were admitted to Department of Neurology Center,The Third Affiliated Hospital of Chongqing Medical University,from January 2020 to December 2022 and underwent EVD,among whom 13 patients underwent LTEVD(LTEVD group)and 32 patients underwent conventional EVD(EVD group).Related data were recorded for both groups,including general information,postoperative catheter-related complications,and postoperative management,to investi-gate the effect on reducing the rate of intracranial infection.According to the presence or absence of intracranial infection after surgery,the patients were divided into the infection group with 10 patients and non-infection group with 35 patients,and related clini-cal data were analyzed to investigate the risk factors for intracranial infection.Results:The LTEVD group had a significantly lower secondary infection rate of catheterization days than the EVD group[2.40‰(1/417)vs.27.19‰(9/331),P=0.009].The duration of catheterization was 14-85 days[27.00(22.50,36.50)days]in the LTEVD group and 8-22 days[9.00(8.00,11.50)days]in the EVD group,suggesting that the LTEVD group had a significantly longer duration of catheterization than the EVD group(P=0.000).The multivariate logistic regression analysis showed that the times of cerebrospinal fluid sampling was an independent risk factor for post-operative intracranial infection in patients undergoing EVD,and the use of LTEVD was a protective factor against intracranial infection after EVD.Conclusion:Compared with conventional EVD,LTEVD can safely prolong the duration of catheterization and reduce the rate of postoperative intracranial infection in patients undergoing EVD.The use of LTEVD procedure and the reduction in the times of cerebrospinal fluid sampling can reduce the risk of postoperative in-tracranial infection.

Central nervous system (CNS) injuries, including stroke, traumatic brain injury, and spinal cord injury, are leading causes of long-term disability. It is estimated that more than half of the survivors of severe unilateral injury are unable to use the denervated limb. Previous studies have focused on neuroprotective interventions in the affected hemisphere to limit brain lesions and neurorepair measures to promote recovery. However, the ability to increase plasticity in the injured brain is restricted and difficult to improve. Therefore, over several decades, researchers have been prompted to enhance the compensation by the unaffected hemisphere. Animal experiments have revealed that regrowth of ipsilateral descending fibers from the unaffected hemisphere to denervated motor neurons plays a significant role in the restoration of motor function. In addition, several clinical treatments have been designed to restore ipsilateral motor control, including brain stimulation, nerve transfer surgery, and brain-computer interface systems. Here, we comprehensively review the neural mechanisms as well as translational applications of ipsilateral motor control upon rehabilitation after CNS injuries.

Objective:To investigate the effect of arthroscopically-assisted open reduction and internal fixation of intra-articular distal radius fracture.Methods:A retrospective cohort study was made on clinical data of 44 patients with distal radial intraarticular fracture admitted to Jing′an District Central Hospital, Fudan University between June 2017 and August 2020. There were 13 males and 31 females, at age of 35-85years [(62.5±12.9)years]. According to AO/OTA fracture classification system, there were 7 patients with type B and 37 with type C. Open reduction and internal fixation with volar plate was used in all patients, among which 22 were operated on using arthroscopy assistance (arthroscopy group) and 22 were operated on with traditional intraoperative fluoroscopy (fluoroscopy group). The operation time in both groups and triangular fibrocartilage complex (TFCC) injury and fracture displacement in arthroscopy group were recorded. Patient-rated wrist evaluation (PRWE) score, disabilities of the arm, shoulder and hand (DASH) questionnaire and range of wrist motion were compared between the two groups at 12 months after operation. The incidence of complications was observed.Results:All patients were followed up for 12-15 months [(13.3±1.1)months]. The operation time in arthroscopy group was (104.0±40.5)minutes, longer than (71.3±32.1)minutes in fluoroscopy group ( P<0.05). In arthroscopy group, 14 patients (64%) with TFCC injury were diagnosed intraoperatively, with the fracture displacement gap and step for 0.8 (0.3, 0.8)mm and 1.0 (0.3, 1.5)mm under arthroscopic vision, which were reduced to 0.3 (0.0, 0.5)mm and 0.5 (0.0, 0.5)mm after arthroscopically-assisted reduction (all P<0.05). The PRWE score in arthroscopy group was (9.8±4.9)points at 12 months after operation, lower than (13.4±5.8)points in fluoroscopy group ( P<0.05). The DASH questionnaire in arthroscopy group was (9.0±5.0)points at 12 months after operation, lower than (13.0±6.1)points in fluoroscopy group ( P<0.05). The dorsal extension and posterior rotation of the wrist in arthroscopy group were (73.8±8.9)° and (82.5±8.0)°, higher than (65.8±14.2)° and (76.3±10.4)° in fluoroscopy group (all P<0.05). There were no postoperative complications such as loosened or broken screws, vascular nerve damage, incision infection or traumatic arthritis in both groups. Conclusion:Arthroscopic-assisted open reduction and internal fixation of intra-articular distal radius fracture can increase the accuracy of joint surface reduction, improve postoperative wrist function and confirm the diagnosis of TFCC injury during operation.

At 2:28 p.m. local time on 12 May, 2008, the Wenchuan earthquake struck with a magnitude of 8.0. After the earthquake, 1364 injured persons, including 732 women and 632 men, were admitted to Deyang People's Hospital. The ages of the injured persons ranged from 0.2 years to 102 years (mean, 42.5 years). Of all injured persons, 4.65% aged under 7 years, 13.84% between 7 and 18 years, 39.57% between 19 and 45 years, 24.48% between 46 and 65 years, and 17.46% above 65 years. A total of 1713 injuries were found in all the injured persons, and the predominant injuries were found in limbs, body surface, head and chest. The incidence of the multiple injuries was 23.64%. Eighteen persons with abdominal injuries received operation. Prompt, accurate and systematic evaluation of the injury is necessary in raising the rescue efficiency. Treating the injured persons according to a classification optimizes the usage of the limited medical resources. Early definitive operation is crucial in rescuing the lives of the injured persons, and the treatment should be applied within 24 hours after the earthquake, then the emphasis of the rescue work should shift to helping orthopedic surgeons with operation and debridement.
