A new modified inside-out repair technique of arthroscopic meniscal repair for peripherally torn menisci is described. Under arthroscopic control, after conventional inside-out technique using meniscal repair set using outside-in technique with 18-gauge needle, horizontal mattress sutures of absorbable monofilament(PDS 2-0) were placed across the tom site and tied over the capsule or fascia. Nearly all portions of meniscus were possible with this technique except most posterior and anterior portions. As this is the modification of inside-out technique, neurovascular complications could be avioded. The problem of outside-in technique, knot irritation inside joint could be avoided also because the knot is outside of the joint.

Objective:To investigate the value of quantitative electroencephalography (qEEG) in the evaluation of thrombolytic efficacy in acute cerebral infarction.Methods:A prospective cohort study was conducted. Ninety-four patients with acute cerebral infarction who received intravenous thrombolysis admitted to the department of emergency of Qinhuangdao First Hospital from October 2019 to September 2020 were enrolled. The relative energy values of δ, θ, α and β waves in qEEG before and 2 hours, 24 hours and 7 days after intravenous recombinant tissue plasminogen activator (rt-PA) thrombolysis were dynamically monitored, and the power ratio index [DTABR, DTABR = (δ+θ)/(α+β)] was calculated. The National Institutes of Health stroke scale (NIHSS) score was also recorded. The reduction of NIHSS score ≥ 3 or the disappearance of neurological symptoms were regarded as effective thrombolytic therapy. The changes of DTABR before and after thrombolysis in patients with effective and ineffective thrombolysis were analyzed, and the correlation between DTABR and NIHSS score was analyzed by Pearson method.Results:A total of 94 patients were enrolled, including 64 males and 30 females. The average age was (61.71±10.11) years from 36 to 89 years old. Thrombolysis was effective in 57 cases and ineffective in 37 cases. Compared with before thrombolysis, DTABR of the effective group was significantly decreased at 2 hours, 24 hours and 7 days after thrombolysis (left cerebral infarction: 1.87±1.45, 1.59±0.88, 1.58±0.90 vs. 3.82±2.60; right cerebral infarction: 1.55±0.57, 1.41±0.50, 1.35±0.44 vs. 3.20±1.63, all P < 0.05). DTABR did not change or increase significantly at 2 hours, 24 hours and 7 days after thrombolysis compared with before thrombolysis (left cerebral infarction: 3.56±2.57, 3.48±2.19, 3.54±2.50 vs. 3.11±1.62; right cerebral infarction: 5.29±3.93, 5.33±3.94, 5.19±4.52 vs. 4.73±2.43, all P > 0.05). Pearson correlation analysis showed a significant positive correlation between DTABR and NIHSS score in patients with acute cerebral infarction (r = 0.691, P < 0.01).Conclusion:The quantitative index of qEEG, DTABR, can accurately and quickly monitor the process of thrombolysis in acute cerebral infarction, and can effectively evaluate the effect of thrombolysis in patients.

With the concepts of minimal invasive surgery and precision medicine embedding deeply in modern medicine, traditional clinical treatment strategies are constantly updated due to the rapid progression of medical research. Systematic dissection of the regional lymph nodes is a key component in the surgical therapy of gynecologic malignancies, however it may result in a series of complications, such as lower extremity lymphedema, deep venous thrombosis, immune disorders and so on, which seriously impact the patients' quality of life. The necessity of systematic lymphadenectomy and the extent of lymph nodes resection have always been one of the most controversial issues in gynecologic oncology. In recent years, the extensive application of sentinel lymph node (SLN) technology has been increasingly used in the treatment of gynecologic malignancies, which may provide important guidance on this issue. This article reviews the clinical application status, detection methods, detection efficiency, and current controversies regarding SLN mapping and biopsy in cervical cancer, endometrial cancer, ovarian cancer and vulvar cancer, discussing the application value of SLN technology in gynecologic oncology.
