The anterior cruciate ligament (ACL), anterolateral complex (ALC) and lateral meniscus (LM) maintain the anterolateral rotatory stability of the knee and control the internal rotation of the tibia. Anterolateral rotatory instability (ALRI) of the knee is not uncommon in clinic, and its main injury mechanism is non-contact injury. A pivot shift test or a tibial internal rotation test can indicate ALRI while X-ray, CT, MRI and ultrasound can assist in its diagnosis and differential diagnosis. For acute ALRI, good technique of ACL reconstruction is the basis to avoid postoperative residual ALRI, and anterolateral ligament reconstruction and extra-articular tenodesis are optional as appropriate. For chronic cases, however, both anterolateral ligament reconstruction and extra-articular tenodesis are effective. This article reviews the progress in research on the diagnosis and treatment of ALRI of the knee, hoping to provide references for its clinical diagnosis and treatment.

This paper reports a case of reparing the tissue defect after resection of a malignant tumor in the glabellar nasion with bilateral modified horizontal advancement flaps. The patient, a 20-year-old female, was admitted to the hospital because of a mass on the nasion between the eyebrows for more than 5 years, with enlargement and ulceration for 5 months. Surgical resection of the tumor was performed. Intraoperative rapid frozen sections showed that the tumor was basal cell carcinoma, and there were no cancer cells at the margins. Bilateral modified horizontal advancement flap repair was performed. At three months after the operation, the incision area healed well, the appearance and eyelid function were normal, and there was no sign of recurrence of basal cell carcinoma. Bilateral modified horizontal advancement flap was effective in repairing the tissue defect after resection of glabellar nasal root basal cell carcinoma.

Objective:To explore the surgical effects of continuous trapezoidal suture method between subcutaneous and subconjunctival tissue in buried-suture double-eyelid blepharoplasty.Methods:A retrospective study was conducted on patients who underwent the operation of continuous trapezoidal suture method between subcutaneous and subconjunctival tissue in buried-suture double-eyelid blepharoplasty at the Department of Plastic and Aesthetic Surgery of Qingdao Municipal Hospital from September 2021 to September 2023. Six points were marked on the skin surface of the designed double eyelid line on patient' s upper eyelid, 8 points were marked on the corresponding conjunctival surface of the designed double eyelid line. A 6-0 nylon thread attached with one needle on each end was used for suturing, with two ends running through and between the subcutaneous and subconjunctival layers alternatively, forming a " trapezoidal" shape of path. Finally, two ends exited at the same point on the most lateral side of the designed double eyelid line on skin surface and were tied together with the knot hidden within the orbicularis oculi muscle. The morphology of the double eyelids and postoperative complications were observed and evaluated after surgery, the follow-up period was at least 6 months. At the last time of follow-up, the satisfaction rates were evaluated by patients themselves. Four aspects of the surgical effects of the double eyelids were put into the evaluation system, which were radian, width, smoothness and symmetry, with score from 0-5 points for each. The total score was 0-20 points, of which 17-20 points indicated high satisfaction, score of 13-16 points indicated relative satisfaction, ≤ 12 points indicated dissatisfaction.Results:A total of 52 female patients were included, aged 18 to 29 years old, with an average age of 22.5 years. Among all patients, 33 cases had shallow double eyelid lines while 19 cases had single eyelids. All patients’ upper eyelids were relatively thin and without obvious looseness. The surgical procedures were all done smoothly and successfully, with an average operation time of (0.72±0.13) h. Immediately after surgery, the radian of the double eyelid lines on both sides looked smooth, the widths of the double eyelids were also basically symmetrical. During the follow-up period of 6-12 months postoperatively, the morphologies of the double eyelids were relatively natural and realistic, the double eyelid lines and widths remained deep and stable, and the incision scars were left unobvious for all patients. Besides, no complications such as ptosis, incomplete upper eyelid closure and ectropion were observed. Among the 52 patients, 45 cases were highly satisfied with the surgical result (17-20 points) , 7 were relatively satisfied (13-16 points) , while none of them required reoperation.Conclusions:The continuous trapezoidal suture method between subcutaneous and subconjunctival tissue in buried-suture double-eyelid blepharoplasty has advantages of short operation time, good and stable surgical effects such as natural and realistic morphology of double eyelids, few complications, and high patients' satisfaction rate.

Objective To investigate the predictive value of combined plasma gluconic acid(GA),fumaric acid(FA),and pseudouridine levels at admission for acute kidney injury(AKI)in elderly patients with acute myocardial infarction(AMI).Methods A total of 78 elderly AMI patients transferred from Emergency Department to Coronary Care Unit in Fuwai Hospital during Decem-ber 2021 and July 2022 were enrolled in this prospective study.They were divided into AKI group(40 cases)and non-AKI group(38 cases)according to whether they developed AKI during hospi-talization.Plasma levels of GA,FA and pseudouridine were quantitatively detected with liquid chromatography-tandem mass spectrometry.ROC curve was plotted to assess the predictive value of these three plasma metabolites for AKI in AMI patients.Multivariate logistic regression analy-sis was applied to analyze the clinical risk factors for AKI.Results There were no statistical differences in the plasma levels of GA,FA and pseudouridine between the AKI group and the non-AKI group(P＞0.05).ROC curve analysis revealed that the plasma levels of the three indicators had no predictive value for the development of AKI in elderly AMI patients(AUC=0.576,95％CI:0.449-0.704,P=0.246;AUC=0.595,95％CI:0.467--0.721,P=0.154;AUC=0.563,95％CI:0.435-0.692,P=0.337).Multivariate logistic regression analysis revealed that left ventricu-lar ejection fraction(LVEF)was an independent predictor for AKI development in elderly AMI patients(OR=0.923,95％CI:0.870-0.978,P=0.007).Conclusion Plasma GA,FA and pseud-ouridine cannot predict the development of AKI in elderly AMI patients,while,LVEF is an inde-pendent predictor for the development.

Objective:To compare the clinical effects of platelet-rich plasma (PRP) and sodium hyaluronate on rotator cuff injury.Methods:From February 2022 to December 2022, 226 patients with rotator cuff injury caused by military training were treated at Department of Orthopaedics, Jinling Hospital, School of Medicine, Nanjing University. They were all male, aged (24.5±3.7) years, and their time from injury to treatment was (4.6±2.2) months. They were divided into 2 even groups according to different treatments: an observation group of 113 cases into whose subacromial space PRP was injected, and a control group of 113 cases into whose subacromial space sodium hyaluronate was injected. In both groups, the injection was performed once a week for consecutive 3 weeks. The 2 groups were compared in terms of visual analogue scale (VAS) and Constant-Murley shoulder function scale (CMS) before treatment and 4 and 8 weeks after treatment, and the levels of TNF- α and IL-6 in the shoulder synovial fluid before treatment and 8 weeks after treatment. Results:There was no statistical difference between the 2 groups in general clinical data before treatment, indicating comparability ( P>0.05). At 4 and 8 weeks after treatment, compared with the pre-treatment values, the VAS scores were significantly decreased and the Constant-Murley scores significantly increased in both groups ( P<0.001). At 4 and 8 weeks after treatment, the VAS scores in the observation group (3.1±0.9 and 1.5±0.5) were significantly lower than those in the control group (3.7±0.8 and 2.3±0.6) while the Constant-Murley scores in the observation group (58.6±4.5 and 72.2±4.1) significantly higher than those in the control group (55.2±5.3 and 67.8±5.0) ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the 2 groups were significantly lower than the levels before treatment ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the observation group [(2.9±0.9) μg/L and (0.8±0.2) μg/L] were significantly lower than those in the control group [(4.0±0.4) μg/L and (1.1±0.4) μg/L] ( P<0.001). Conclusion:Injection of PRP or sodium hyaluronate can relieve pain and improve shoulder function obviously in patients with rotator cuff injury, but PRP is superior to sodium hyaluronate in the treatment of rotator cuff injury.

Objective To explore the determinants and mechanism of trust transfer among patients for online health websites using the equation model. Methods A trust transfer model was built based on the theory of group convergence and doctor-patient interaction. 225 doctor records of online consultations were collected from Haodf, an online health website by data crawling from May 1 to Nov.30, 2017. Multiple regression was used for an empirical analysis. Results The patients' online trust has a positive impact on the physicians'trust offline, with a regression coefficient of 0.94, being significant at the level 0.01. Patient incentives, group size, and frequency of group interaction are important for online patient trust. Meanwhile, patient motivation, group size, and patient online efforts all have significant effect on patient offline trust. Conclusions Online patients' trust affects their offline trust significantly. Developers of online health websites can increase the online trust of patients by motivation and interaction, which help create a desirable medical environment and encourage their trust to offline doctors, contributing to higher medical satisfaction.
