Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Objective:To investigate the therapeutic effect of bidirectional-traction, Steinmann pin poking reduction,anatomic plate and raft technique in the treatment of hyperextension tibial plateau fractures.Methods:The data of 25 patients with hyperextension tibial plateau fractures admitted to Qilu Hospital of Shandong University (Qingdao) from July 2017 to June 2022 were retrospectively analyzed. According to the treatment methods, they were divided into bidirectional-traction group (treated with bidirectional-traction, Steinmann pin poking reduction, anatomic plate and raft technique) and open reduction group (treated with open reduction, bone grafting and two plates fixation). The bidirectional-traction group included 14 patients, with 8 males and 6 females; the age was 50.29±9.23 years (range, 38-61 years). The cause of the injury was a traffic accident in 4 patients, a fall from height in 7 patients and a fall from standing height in 3 patients. According to Schatzker classification, there were 5 Schatzker type V and 9 type VI fractures. The open reduction group included 11 patients (7 males and 4 females); with a mean age of 58.00±10.58 years (range, 48-69 years). 3 cases were injured by traffic accident, 6 cases by falling from height, and 2 cases by falling from standing height. According to Schatzker classification, there were 4 type V and 7 type VI. Preoperative waiting time, operative time, blood loss and percentage of blood loss, incision length, fracture healing time, tibial posterior inclination, medial proximal tibial angle, visual analogue scale (VAS) on the first day after surgery, Hospital for Special Surgery (HSS) score 6 months after surgery were compared between the two groups.Results:Patients in both groups were followed up for more than 6 months. The follow-up time was 7 to 48 months with an average of 22.76 months. There were significant differences in the preoperative waiting time [6 (4, 8) d vs. 8 (7, 11) d, W=114.00, P=0.043], the incision length [15.0 (12.5, 16.0) cm vs. 30.0 (28.0, 31.0) cm, W=154.00, P<0.001], postoperative VAS [4 (3, 4) points vs. 5 (5, 6) points, W=143.00, P<0.001], blood loss [147 (107, 206) ml vs. 267 (191, 362) ml, W=116.00, P=0.033], blood loss percentage [2.95% (2.58%, 5.20%) vs. 6.40% (4.05%, 7.00%), W=118.00, P=0.027] between the bidirectional-traction group and open reduction group. There were not significant differences in the operation time [120 (118, 120) min vs. 119 (101, 154) min, W=68.50, P=0.656], fracture healing time (8.18±1.03 weeks vs. 8.86±1.27 weeks, t=1.49, P=0.149), HSS score (8.43±3.72 vs. 85.18±7.73, t=1.28, P=0.221) and medial proximal tibial angle 6 months after surgery (87.66°±1.53° vs. 86.47°±2.24°, t=1.57, P=0.130) between the two groups. Postoperative tibial posterior inclination was improved in both groups. There was no significant difference in the tibial posterior inclination before surgery, immediately after surgery and 6 months after surgery (-14.96°±6.44°, 5.55°±1.02°, 5.61°±0.82°) in the bidirectional-traction group and -12.26°±2.93°, 7.07°±3.21° and 7.14°±3.17° in the open reduction group, P>0.05). There were no postoperative complications such as acute compartment syndrome or knee stiffness in both groups. Conclusion:The treatment of hyperextension tibial plateau fracture with bidirectional-traction, Steinmann pin poking reduction, anatomic plate and raft technique can shorten preoperative waiting time, reduce incision length, decrease blood loss and lower VAS. It is a minimally invasive, rapid and effective method, which has achieved good clinical results and is worth promoting.

ObjectiveTo investigate the effect and mechanism of Mori Folium extract on the glucose and lipid metabolism disorders in the liver of rats with type 2 diabetes mellitus （T2DM） through the phosphatidylinositol 3-kinase/protein kinase B/peroxisome proliferation-activated receptor α/carnitine palmitoyl transferase-1 （PI3K/Akt/PPARα/CPT-1） signaling pathway. MethodThe T2DM model was induced by the high-fat diet combined with the intraperitoneal injection of streptozotocin （STZ）. The model rats were randomly divided into a model group， a metformin （0.2 g·kg^-1） group， and a Mori Folium water extract （4.0 g·kg^-1） group according to blood glucose and body weight. In the 8-week administration， fasting blood glucose was measured at the same time every week. The histomorphological and fat changes in the rat liver were observed by hematoxylin-eosin （HE） staining and oil red O staining. The levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） in the serum were measured by biochemical methods. Western blot （WB） was used to quantitatively detect the protein expression of p-PI3K，PI3K，p-Akt，Akt，PPARα，and CPT-1 in the rat liver. ResultAfter 8-week administration， the blood glucose of rats was higher in the model group than that in the control group （P<0.01）， and lower in the Mori Folium water extract group than that in the model group （P<0.01）. The results of HE staining showed that the liver tissue structure of the control group was complete， and the hepatocytes were arranged radially around the central vein， while the hepatocyte injury in the model group was obvious. Compared with the model group， the Mori Folium water extract group showed improved vacuolar degeneration and no lesions such as small bile duct hyperplasia. Oil red O staining showed that there was no obvious steatosis and necrosis in the hepatocytes of rats in the control group， and no lipid droplets in the hepatocytes were observed， while the model group showed increased lipid droplets. Mori Folium significantly reduced the lipid droplets in the liver. Biochemical analysis showed that the levels of TC， TG， LDL-C， AST， and ALT in the model group were significantly higher than those in control group （P<0.01）. The levels of TC， TG， LDL-C， AST， and ALT in the Mori Folium water extract group were significantly lower than those in the model group （P<0.05，P<0.01）. WB showed that the protein expression of p-PI3K/PI3K， p-Akt/Akt， PPARα， and CPT-1 in the model group were lower than those in the control group （P<0.01）. Mori Folium water extract could increase the protein expression of p-PI3K/PI3K， p-Akt/Akt， PPARα， and CPT-1 （P<0.05 or P<0.01）. ConclusionThe hypoglycemic mechanism of Mori Folium water extract may be related to the regulation of the PI3K/Akt/PPARα/CPT-1 signaling pathway.

This study evaluated the regulatory effect of curcumin on memory follicular T cells (mTf) in obese mice with ulcerative colitis on the basis of determining its effective treatment of ulcerative colitis in obese mice. Forty male leptin mutant (ob/ob) mice were randomly divided into control group, control + curcumin group, dextran sodium sulfate (DSS) group and DSS + curcumin group, with 10 mice in each group. Mice in the DSS group and the DSS + curcumin group were induced by DSS to establish chronic ulcerative colitis model, and mice in the control + curcumin group and the DSS + curcumin group were given curcumin (200 mg·kg^-1·d^-1) by intragastric administration. Mice were sacrificed under anesthesia, and colon mass index, colon length and other conditions were observed in each group. Pathological injury of colonic was performed after HE staining. The levels of memory follicular helper T cells (mTfh) and memory follicular regulatory T cells (mTfr) in spleen of mice were detected by flow cytometry. The expression levels of interleukin-10 (IL-10) and interleukin-17A (IL-17A) in colon tissue were detected by ELISA. The results showed that curcumin significantly increased the body weight and colon length of obese mice with colitis, and decreased the colon weight, colon mass index and pathological score (P < 0.05). Curcumin significantly reduced the levels of central memory follicular T cells (cmTf), mTfh1, mTfh17 cells and the content of pro-inflammatory cytokine IL-17A (P < 0.01). The levels of effector memory follicular T cells (emTf) and mTfr and the content of anti-inflammatory cytokine IL-10 were increased (P < 0.05, P < 0.01). Therefore, curcumin may treat colitis in obese mice by regulating the balance of mTf cell subsets.

Objective:To compare the efficacy of lateral elbow dislocation approach with non-dislocation approach for open reduction and internal fixation of distal humeral coronal fracture.Methods:A retrospective cohort study was used to analyze the clinical data of 26 patients with distal humeral coronal fracture admitted to Qilu Hospital (Qingdao) of Shandong University from January 2018 to October 2021, including 10 males and 16 females, aged 15-80 years [(51.6±4.9)years]. According to Dubberley classification, there were 10 patients with type 2A, 5 with type 2B, 6 with type 3A and 5 with type 3B. Overall, 12 patients were operated via lateral elbow dislocation approach (dislocation approach group) and 14 via lateral elbow non-dislocation approach (non-dislocation approach group). The operation time, intraoperative bleeding volume, incision healing, three-dimensional CT assessment of the reduction within one week after surgery (separation or step>2 mm as poor), Mayo elbow performance score (MEPS) at 3 months after surgery and fracture healing at the last follow-up were recorded in both groups. Complications were also compared between the two groups.Results:All patients were followed up for 3-18 months [(10.5±3.3)months]. The operation time was (146.9±15.5)minutes in dislocation approach and (122.7±11.1)minutes in non-dislocation approach group ( P>0.05). The intraoperative bleeding volume was (113.3±9.7)ml in dislocation approach and (112.9±10.1)ml in non-dislocation approach group ( P>0.05). All incisions healed uneventfully in stage I. All patients had good reduction in dislocation group, while only 7 patients had good reduction and the other 7 patients presented a separation or step>2 mm in non-dislocation group ( P<0.05). The MEPS was (90.0±1.4)points in dislocation approach group at 3 months after surgery, including 9 patients being rated as excellent and 3 good, with the excellent and good rate of 100%. In constrast, the MEPS was (78.9±2.9)points in non-dislocation approach group at 3 months after surgery, including 5 patients being rated as excellent, 4 good, 4 fair and 1 poor, with the excellent and good rate of 64.3% ( P<0.05). All fractures were healed at the last follow-up. In non-dislocation approach group, osteoarthritis occurred in 7 patients, including 3 with screw protrusion, 2 with heterotopic ossification and 2 of advanced age with osteophyte formation around the joint. In dislocation approach group, osteoarthritis occurred only in 2 patients of advanced age, showing osteophyte formation around the elbow joint, with no screw cutting or heterotopic ossification. Conclusion:For distal humeral coronal fracture, the lateral elbow dislocation approach is able to provide complete exposure of the articular surface, obtain anatomic reduction, restore elbow function and reduce complications when compared with the non-dislocation approach.

Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.

Objective:To compare reconstruction of acromioclavicular ligament versus internal fixation of acromioclavicular joint with clavicle hook plate in the treatment of Rockwood Ⅲ-Ⅴ acromioclavicular dislocation by reconstruction of coracoclavicular ligament with suture anchor.Methods:A retrospective analysis was conducted of the 56 patients who had been treated for Rockwood Ⅲ-Ⅴ acromioclavicular dislocation from January 2015 to June 2019 at Department of Orthopaedic Trauma, Qilu Hospital of Shandong University (Qingdao). Of them, 26 were treated by reconstruction of coracoclavicular ligament with suture anchor plus reconstruction of acromioclavicular ligament (reconstruction group) and 30 by reconstruction of coracoclavicular ligament with suture anchor plus internal fixation of acromioclavicular joint with clavicle hook plate (plate group). The 2 groups were compared in terms of operation time, intraoperative blood loss, Constant-Murley score and Subjective Shoulder Rating System (SSRS) score at the last follow-up, and complications.Results:The 2 groups were comparable because there were no significant differences between them in the baseline data before operation ( P>0.05). The reconstruction group was followed up for 6 to 15 months (average, 7.9 months) while the plate group for 7 to 18 months (average, 11.3 months). The average operation time was (79.9±12.6) min for the reconstruction group and (69.1±8.5) min for the plate group, showing a significant difference ( P<0.05). No significant difference was found between the 2 groups in the intraoperative blood loss [(68.5±19.1) mL versus (65.0±16.6) mL] ( P>0.05). The differences were statistically significant between the 2 groups in Constant-Murley score (87.9±3.4 for the reconstruction group versus 91.9±3.5 for the plate group) and in SSRS score (85.1±4.1 for the reconstruction group versus 88.6±3.0 for the plate group) ( P<0.05). All the wounds healed well in the reconstruction group except for one patient who reported numbness around the wound which disappeared spontaneously 3 months postoperation. In the plate group, incision infection occurred in 2 cases, the redness and swelling in one which responded to dressing change 3 weeks later and numbness around the incision in one which was recovered 5 months after operation. Conclusions:Both surgical procedures can achieve good to excellent clinical outcomes. Although reconstruction of both acromioclavicular and coracoclavicular ligaments takes more operation time, it may lead to better Constant-Murley and SSRS scores and fewer complications, and spare secondary operation.

OBJECTIVE: To explore clinical effects of ultrasound-guided minimal traverse-cross technique repair for acute closed Achilles tendon ruptures. METHODS: From January 2015 to March 2017, 20 patients with acute closed Achilles tendon rupture were treated by minimal traverse-cross technique repair with ultrasound guided. Among them, including 13 males and 7 females, aged from 28 to 49 years old with an average of(31.3 ±4.5) years old. All patients were single side injury. Fifteen patients on the left side and 5 patients were on the right side. The time from injury to operation ranged from 1 to 5 days with an average of (2.5±0.7) days. Operative time, postoperative complications were observed, and AOFAS score before and after operation at 12 months were compared. RESULTS: All patients were followed up for 12 to 27 months with an average of(15.2±4.9) months. Operative time ranged from 33 to 65 min with an average of(43.7±5.6) min. Incision of one patient were continued oozing and improved after changing dressings, other patients were healed at stage I. No sural nerve irritation symptoms and palindromic rapture of heel tendon occurred. AOFAS score was improved from 65.2±7.4 before operation to 97.7±4.7 after operation at 12 months (t=22.5, <0.01); 18 patients got excellent results and 2 good. CONCLUSIONS Ultrasound-guided minimal traverse-cross technique repair for acute closed Achilles tendon ruptures, which promise minimal incision, protect sural nerve, ensure quality of tendon anastomosis and fixation, and is a ideal method for repairing acute closed Achilles tendon ruptures.

Objective: To evaluate a self-designed novel anatomical bone plate for fractures of ulnar coronoid process in cadaveric specimens. Methods: Our database search in the Imaging Center, Qilu Hospital of Shandong University (Qingdao) yielded CT reconstruction images of 45 normal adult elbows (26 males and 19 females) which met our criteria. On the 3D reformatted CT images, sagittal curvature angle of the ulnar coronal process (△1), tangent angle of the coronal process apex to olecranon fossa (△2), projective length (L) and projective height (H) were measured; the transverse width of the coronal process was also measured at 5 mm and 10 mm from the tip (K1 and K2). The minimum value was used for △2° in order to avoid cutting into the joint while the mean value for other parameters. After the shape of the plate and angles of the screws were designed using computer 3D software, a new anatomic plate for coronal process was produced. Five cadaver specimens were used to test the internal fixation of the coronal process with our novel anatomic bone plate. Attachment of the bone plate to the coronal process and screw penetration into the joint cavity were observed by X-ray and 3D CT scanning. Results: △1 was 45.52°±6.07°, △2 65.25°±7.09° (the minimum value 53.2°), L 52.27±7.78 mm, H 21.62±2.63 mm, K1 16.32±2.22 mm and K2 14.58±2.18 mm. Our new anatomic bone plate was designed based on the above data. X-ray and 3D CT scan after plate internal fixation showed that our self-designed bone plate produced fine attachment and no screws penetrated into the joint. Conclusion Our new anatomical bone plate may perfectly fit the anatomy of the adult ulnar coronal process in size and shape so that the coronary process can be fully covered and no screws will penetrate into the joint cavity.
