Intraocular pressure detection has a great significance for understanding the status of eye health, prevention and treatment of diseases such as glaucoma. Traditional intraocular pressure detection needs to be held in the hospital. It is not only time-consuming to doctors and patients, but also difficult to achieve 24 hour-continuous detection. Microminiaturization of the intraocular pressure sensor and wearing it as a contact lens, which is convenient, comfortable and noninvasive, can solve this problem because the soft contact lens with an embedded micro fabricated strain gauge allows the measurement of changes in corneal curvature to correlate to variations of intraocular pressure. We fabricated a strain gauge using micro-electron mechanical systems, and integrated with the contact lens made of polydimethylsiloxane (PDMS) using injection molding. The experimental results showed that the sensitivity was 100. 7 µV/µm. When attached to the corneal surface, the average sensitivity of sensor response of intraocular pressure can be 125.8 µV/mm Hg under the ideal condition.

Professor HE Tianyou's unique understanding and treatment characteristics for intractahle facial paralysis are introduced. In clinical practice professor HE highly values acupoint selection and manipulation application, and integrates Chinese and western medicine to flexibly choose acupoints and formulate prescriptions according to syndrome differentiation and location differentiation, besides, he creates several specialized manipulation methods including "tug-of war opposite acupuncture method" and "tractive flash cupping". Based on strengthening body and dredging collaterals. more attention is given on stimulation to local paralyzed facial nerves; meanwhile acupuncture and medication are combined to improve clinical efficacy. During the treatment, the important role of psychological counseling on patient's anxiety is emphasized, and comprehensive treatment is given physically and psychologically in order to achieve the purpose of total rehabilitation.

Objective:The efficacy of using a single electrical or magnetic stimulation for treating pelvic floor dysfunction is limited.This study aims to investigate the efficacy of radiofrequency combined with magnetic stimulation treatment for mild to moderate pelvic organ prolapse. Methods:Patients who completed the treatment in the Third Xiangya Hospital,Central South University were screened,and were divided into 2 groups based on different treatment plans.There were 28 patients who completed magnetic stimulation therapy(the magnetic stimulation therapy group)and 21 patients who completed radiofrequency combined with magnetic stimulation therapy(the combined treatment group).The pelvic organ prolapse quantitation(POP-Q),pelvic floor muscle strength,and pelvic floor ultrasound results were analyzed to assess the efficacy before and after the treatment in both groups,and the POP-Q results of 3 months after the treatment were used to evaluate the maintenance effect of the treatment mode. Results:The POP-Q evaluation results of Aa,Ap,and C points after the treatment in both groups were better than those before the treatment,with statistical significance(all P＜0.05).The Aa point POP-Q result of the combined treatment group was better than that of the magnetic stimulation therapy group,with statistical significance(P＜0.05).Pelvic floor ultrasound evaluation showed that the bladder neck position during the valsalva maneuver in the combined treatment group was higher than that in the magnetic stimulation treatment group,with statistical significance(P＜0.05).The persistence effect of the combined treatment group was long better than that of the magnetic stimulation treatment group,with significant statistical significance(P＜0.01). Conclusion:The combined treatment is more effective and has a longer lasting effect than single magnetic stimulation treatment.
