Objective:To explore the value of different levels of sonographers and International Ovarian Tumor Analysis (IOTA) simple rules in judging benign and malignant ovarian tumors.Methods:The ultrasound images of 182 patients treated in Beijing Tiantan Hospital, Capital Medical University from January 2017 to November 2020 with ovarian tumors were retrospectively analyzed. The ovarian tumors were diagnosed by two senior sonographers and two junior sonographers without knowing the pathological diagnosis. Another junior sonographer trained in IOTA terminology and simple rules applied IOTA simple rules to diagnose 182 ovarian tumors. The sensitivity, specificity, positive predictive value and negative predictive value of the diagnosis of ovarian tumors by senior sonographers, junior sonographers and IOTA simple rules were calculated using the postoperative pathological diagnosis as the gold standard. The Kappa value was calculated for the consistency between different levels of sonographers and the IOTA simple rules and pathological diagnosis.Results:Of the 182 cases, 61 cases were pathologically benign and 121 cases were pathologically malignant. The diagnostic sensitivity, specificity and accuracy of senior sonographers were 93.4%, 99.2%, 97.2%, respectively, Kappa value was 0.938. The diagnostic sensitivity, specificity, and accuracy of junior sonographers were 80.3%, 90.0%, 86.8%, respectively, Kappa value was 0.704. The diagnostic sensitivity, specificity and accuracy of IOTA simple rules(When an uncertain tumor was classified as malignant) were 95.0%, 73.5%, 80.7%, respectively, Kappa value was 0.614. The diagnostic sensitivity, specificity and accuracy of IOTA simple rules(when an uncertain tumor was excluded) were 94.2%, 90.9%, 92.0%, respectively, Kappa value was 0.834.Conclusions:IOTA simple rules is a very useful diagnostic tool for junior sonographers to judge benign and malignant ovarian tumors. When IOTA simple principle is judged as an uncertain case, it is recommended to refer to experienced senior sonographers for further diagnosis.

By collecting and analyzing information regarding the history development, current situation, legislation, health insurance, education and academic organizations of acupuncture in Israel, the development characteristics of acupuncture in Israel were summarized. The overall traditional medicine developed well in Israel, yet acupuncture have only appeared in Israel for 18 years. The proposal of Israeli Acupuncture Legislation Act improved the development of health insurance, education and public awareness of acupuncture in Israel. However, improvement in areas of education, legislation and health insurance are still in need. Suggestions are proposed to improve the education quality, acupuncture legislation, international cooperation, volunteer activities and cultural exchanges. In addition, the legislative process of acupuncture in the countries of "the Belt and Road", especially the Middle East countries, are promoted.

Objective: To discuss a method, increasing the resistance and decreasing the power of the levator palpebrae superioris, to treat the upper eyelid retraction, after upper blepharoplasty, and summarize the feasibility and efficacy of this operation. Methods: A total of 33 female patients (42 eyes) with upper eyelid retraction after blepharoplasty were treated. According to preoperative evaluation, an adjusted method, levator tendon membrane and Muller′s muscle compound tissue turnover flap, was selected. Following the incision of past blepharoplasty, scar and adhesions were removed as much as possible. The space between orbital septum and levator palpebral tendon membrane was widely separated, as well as the space between levator palpebral tendon membrane and Muller′s muscle, and the conjunctiva. A composite tissue flap consisting of levator palpebral tendon membrane and Muller′s muscle was formed. At the spot above the end of the composite tissue flap, paralleling to the upper edge of upper tarsal plate, the tissue was stripped. The compound flap was divided into two layers, a deep and a shallow layer, to form the aponeurosis turnover flap with pedicle at the free end. The turnover flap was horizontally sutured to the upper edge of tarsal plate. The buccal fat pad was cut and covered, between the levator palpebral tendon membrane and the orbital septum fat. At the end, conventional blepharoplasty was performed to close the incision. Results: All the incisions were primary healed. Stitches were taken out 7 days after surgery. There was different scar proliferation. The recovery period last 3-6 months. Transplanted buccal fat was survived, without nodule, liquefaction, unevenness or other complications. All patients were followed for 3 to 12 months, with a mean follow-up of 6 months, for static and dynamic assessment. In static evaluation, the upper palpebral margin decreased by 2 mm. The upper palpebral margin decreased by 3 mm on average. Three cases (9%) had insufficiently corrected upper eyelid retraction, 2 cases (6%) recurred upper eyelid retraction in 3 months after operation, while the other 28 cases (85%) showed satisfactory results. Conclusions The upper eyelid tendon membrane and Muller′s muscle compound tissue turnover flap extension is helpful to correct the upper eyelid retraction, caused by blepharoplasty.
