Psychological factors have become significant contributors to the onset and progression of insomnia. This article explored the treatment of insomnia from the perspective of “liver governs wei qi （defensive qi）”. The concept of “liver governs wei qi （defensive qi）” is summarized in three aspects， firstly， the liver assists the spleen and stomach in transformation and transportation， governing the generation of wei qi； secondly， the liver aids lung qi diffusion and dispersion， governing the distribution of wei qi； thirdly， the liver regulates circadian rhythms， governing the circulation of wei qi. It is proposed that the clinical treatment of insomnia should focus on the following methods： for regulating the liver to harmonize the five viscera， and facilitate the circulation of wei qi， medicinals entering the liver channel include Chaihu （Bupleuri radix）， Baishao （Paeoniae Radix Alba）， Zhizi （Gardeniae Fructus）， and Suanzaoren （Ziziphi Spinosae Semen） could be commonly used； for nourishing the liver， the treatment should align with the day-night rhythm， and herbs such as Baihe （Lilium）， Hehuan （Albizia julibrissin）， and Yejiaoteng （Polygoni multiflori caulis） are commonly used； for soothing the liver and address both mental and physical health to calm wei qi， treatment should advocate verbal counseling， psychological regulation， and health education. Ultimately， this treatment approach can free liver qi to flow， soothe qi movement， restore the motion of wei qi， regulate during day and night， balance yin and yang， and resolve insomnia effectively.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To investigate the effect of different timing of urinary catheter removal on postoperative recovery of elderly patients undergoing transurethral resection of prostate (TURP) .Methods:A total of 159 elderly patients undergoing TURP from Beijing Friendship Hospital Affiliated to Capital Medical University from March 2021 to June 2022 were selected as research objects by convenience sampling method, and were divided into the urinary catheter removal within 48 h after surgery group ( n=47), urinary catheter removal within 48 to 72 h after surgery group, urinary catheter removal>72 h after surgery group. The degree of dysuria after catheter removal, incidence of urinary tract infection, secondary catheter insertion rate and postoperative hospital stay were compared among the three groups. Results:The proportion of patients with moderate or above dysuria of the urinary catheter removal within 48 to 72 h after surgery group was lower than those of the urinary catheter removal within 48 h after surgery group and the urinary catheter removal>72 h after surgery group, and the differences were statistically significant ( P<0.05). The incidence of urinary tract infection of the urinary catheter removal within 48 h after surgery group and the urinary catheter removal within 48 to 72 h after surgery group were lower than that of the urinary catheter removal>72 h after surgery group, and the differences were statistically significant ( P<0.05). The rate of secondary catheterization of the urinary catheter removal within 48 to 72 h after surgery group and the urinary catheter removal>72 h after surgery group were lower than that of the urinary catheter removal within 48 h after surgery group, and the differences were statistically significant ( P<0.05). The postoperative hospital stay of the curinary catheter removal within 48 to 72 h after surgery group was shorter than those of the urinary catheter removal within 48 h after surgery group and the urinary catheter removal>72 h after surgery group, and the differences were statistically significant ( P<0.05) . Conclusions:Removing urinary catheter within 48 to 72 h after surgery can effectively reduce the degree of urination difficulty in elderly patients undergoing TURP, the incidence of urinary tract infection and the rate of secondary catheterization, and shorten the postoperative hospital stay.

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 explore effects of different timing of extubation on catheter-related lower urinary tract symptoms and urinary control recovery after extubation in patients with indwelling catheter after general anesthesia.Methods:Using the stratified random selection method, a total of 198 patients who underwent indwelling catheter after general anesthesia in Beijing Friendship Hospital affiliated to Capital Medical University were selected from January 2018 to July 2019. Using the random number table method, they were randomly divided into the observation group (101 cases) and the control group (97 cases) . In both groups, the extubation method was established by evidence-based nursing demonstration and the water sac test results of the material and model of urinary duct in the hospital. In the control group, the timing of extubation was to remove the catheter when the bladder was empty and the patient had no urination intention, and then assist urination when the urination intention appeared. In the observation group, the time of extubation was when the bladder was in a full state and the patient had the intention to urinate, the urinary duct was naturally discharged with urine by abdominal pressure. The lower urinary tract symptoms associated with urinary tube and the recovery of urinary control after extubation were compared between the two groups.Results:The success rate of urination in the observation group was higher than that of the control group, the core lower urinary tract symptom score and incidences of frequency of urination, urgency and acute urinary retention were lower than those of the control group, and the differences were statistically significant ( P<0.05) . The maximum bladder pressure measurement volume and residual urine volume in the observation group were lower than those in the control group, and the urine control rate and maximum urine flow rate at 72 h after extubation were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Extubation in patients with bladder filling and urination after general anesthesia can reduce the incidence and severity of lower urinary tract symptoms associated with the catheter, which help patients recover bladder function and improve urinary control ability.

Objective:To discuss the clinical curative effect of the minimally invasive percutaneous suture technique of eight times for repairing closed injury extensor tendon zone I of finger.Methods:From February 2017 to January 2020, 12 patients (male 8, female 4) with mallet finger deformity were retrospectively studied, with an average age of 35 years (range, 18-50 years). And all the affected fingers were acute closed rupture of extensor tendon in zone I of single finger, 5 cases of the left finger and 7 cases of the right finger. There were 1 case of the thumb finger, 2 cases of the index finger, 3 cases of the middle finger, 4 cases of the ring finger and 2 cases of the little finger. 12 patients with fresh sputum mallet fingers were with 3-0 thread monofilament suture on extensor tendon zone I of finger in the minimally invasive percutaneous suture technique of eight times, and the distal end of the tendon was fixed to the base of the distal phalanx through the bone hole. Removal of the Kirschner wire 6-8 weeks, the brace was used to fix the affected finger in the dorsal extension. The flexion and extension of the affected finger was gradually strengthened. The function of the affected finger was evaluated according to the Crawford standard after operation and follow-up. The active flexion and extension range of motion of each joint of the affected finger and the contralateral healthy finger were measured, and the total action movement (TAM) of the finger were recorded. Finger function was evaluated according to TAM of the American Association of Hand Surgeons.Results:All operations were successfully completed, the operation time of the patients ranged from 18 to 25 min, with an average of 20.1±0.2 min. There was only a small amount of bleeding in the surgery. All 12 cases were followed up and the follow-up periods ranged from 6 to 14 months, with an average of 10.2±1.1 months. Mallet finger deformities were all corrected postoperatively; there were no knot exposure, skin necrosis and other complications. According to the Crawford standard, 9 cases were excellent, 2 cases were good, and 1 case was fair. The excellent and good rate was 91.7% (11/12). The mean active flexion of distal interphalangeal joints on the wounded finger and healthy finger were 82.11°±2.02° and 84.09°±2.01°, the mean active extension of distal interphalangeal joints on the wounded finger and healthy finger were -2.04°±3.01° and 0.02°±1.02°, there were significant differences between them ( t=2.447, 3.246; P=0.019, 0.004). The degrees of active joint activity of wounded finger were: 91.02°±4.01° of the metacar-pophalangeal joint, 94.04°±2.11° of the proximal interphalangeal joint, 83.01°±2.02° of the distal interphalangeal joint, and 265.05°±13.04° of total active activity; the degrees of active joint activity of healthy finger were: 93.01°±3.21° of the metacar-pophalangeal joint, 94.03°±3.07° of the proximal interphalangeal joint, 85.02°±2.01° of the distal interphalangeal joint, and 269.02°±12.10° of total active activity. The TAMs of the healthy side were 269.02°±12.10°, and the TAMs of the affected side were 265.05°±13.04°, there was no significant difference between them ( P>0.05). According to TAM system assessment criteria: excellent in 9 patients, good in 3 patients, and the excellent and good rate was 100% (12/12). Conclusion:The minimally invasive percutaneous suture technique of eight times can well repair closed injury extensor tendon zone I of finger, can have satisfactory treatment outcome in mallet finger with a simple procedure and good outcome. It is a simple, safe, effective method with minimal invasion.

Since December 2019, the corona virus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (2019-nCoV) has been reported in Wuhan, Hubei Province. Almost 70% of patients susceptible to 2019-nCoV are over age of 50 years, with extremely large proportion of critical illness and death of the elderly patients. Meanwhile, the elderly patients are at high risk of osteoporotic fractures especially osteoporotic vertebral compression fractures (OVCF). During the prevention and control of COVID-19 epidemic, orthopedists are confronted with the following difficulties including how to screen and protect OVCF patients, how to accurately diagnose and assess the condition of OVCF patients with suspected or confirmed COVID-19, and how to develop reasonable treatment plans and comprehensive protective measures in emergency and outpatient clinics. In order to standardize the diagnosis and treatment of patients with OVCF diagnosed with COVID-19, the authors jointly develop this expert consensus. The consensus systematically recommends the standardized emergency and outpatient screening and confirmation procedures for OVCF patients with suspected or confirmed COVID-19 and protective measures for emergency and outpatient clinics. Moreover, the consensus describes the grading and classification of OVCF patients diagnosed with COVID-19 according to the severity of illness and recommends different treatment plans and corresponding protective measures based on the different types and epidemic prevention and control requirements.

Objectives:To observe the anatomical location and mechanism of axis ring fractures (ARF) using 3-D CT scans, and propose a new classification for such fractures.Methods:By reviewing prospectively maintained database collecting ARF from 7 medical centers in China, 202 patients were included in this study. According to anatomical location, ARFs were classified into axis arthrosis fracture (AAF) and axis bony damage (ABD). The axis ring was divided into anterior, middle, and posterior rings, based on the border of the pars interarticularis (or pedicle) of axis. According to the features of ARF and previous study, a new classification was proposed based on the anatomical features of different fracture patterns, which was divided into three types and six subtypes (A1, A2, B1, B2, C1 and C2). The incidence of AAF and ABD and their distribution in different location of axis ring and the new classification, were observed.Results:In 202 patients with ARF, 501 anatomical structures were involved. 288 AAFs were found in 178 patients (288/501, 57%), while 213 ABDs were found in 149 patients (213/501, 43%). In anterior ring, 304 structures (304/501, 61%) were involved in injury, with 225 AAF and 79 ABD. In middle ring, 99 structures (99/501, 20%) were involved in injury, and all of them were ABD. In posterior ring, 98 structures (98/501, 19%) were involved in injury, with 63 AAF and 35 ABD. The anterior ring injuries (61%) were more common than middle (20%) or posterior ring (19%). In anterior ring, AAF (84%) were morecommon than ABD (16%); In middle ring, all the injuries were ABD; In posterior ring, AAFs (64%) were more common than ABD (36%). Type A fractures were featured with pedicle fractures and were identified in 30 patients (30/202, 15%). Type A1 fractures were bilateral pedicle fracture lines symmetrically or asymmetrically and identified in 12 (6%) patients; Type A2 fractures were pedicle fracture lineson one side and inferior articular facet injuries or lamina fractures on the otherside and identified in 18 (9%) patients. Type B fractures were featured with superior articular facet injuries or posterior wall of C2 body fractures on one side and identified in 136 patients (67%). Type B1 fractures were superior articular facet injuries or posterior wall of C2 body fractures on one side and pedicle fracture on the other side and identified in 57 (28%) patients; Type B2 fractures were superior articular facet injuries or posterior wall of C2 body fractures on one side and inferior articular facet injuries or lamina fractures on the otherside and identified in 79 (39%) patients. Type C fractures were featured with bilateral superior articular facet injuries or posterior wall of C2 body fractures and identified in 36 patients (18%). Type C1 fractures were bilateral superior articular facet injuries or posterior wall of C2 body fractures symmetrically and identified in 22 (11%) patients; Type C2 fractures were bilateral superior articular facet injuries or posterior wall of C2 body fractures asymmetrically and identified in 14 (7%) patients.Conclusion:ARF could occur in different anatomical locations, and most of these fractures were caused by hyperextension and axial load on superior articular facet on one or two sides. The new CT classification of ARF with three types and six subtypes might provide all fracture patterns, which could be useful for the choice of proper diagnosis and treatment for such fractures.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.
