An infrared thermographic analysis of the sensitization acupoints of women with primary dysmenorrhea.

Objective: To explore the sensitization acupoints of women with primary dysmenorrhea (PD) by comparing infrared radiation temperatures between acupoints and non-acupoints.

Methods: We tested 10 acupoints of every woman with PD and healthy subjects on premenstrual, menstrual, and postmenstrual days using an infrared imaging device. The primary outcome was the absolute value of body surface temperature difference (AVTD) between the left and right sides of the same testing point.

[Clinical observation on different frequency of auricular bloodletting combined with auricular point sticking for acne vulgaris].

Objective: To observe the clinical efficacy of different treatment frequency of auricular bloodletting combined with auricular point sticking for acne vulgaris.

Methods: A total of 90 patients with acne vulgaris were randomized into a treatment group 1 (30 cases, 2 cases dropped off), a treatment group 2 (30 cases, 4 cases dropped off) and a treatment group 3 (30 cases, 5 cases dropped off). Combination therapy of auricular bloodletting and auricular point sticking at Fei (CO), Shenmen (TF), Neifenmi (CO) and Shenshangxian (TGp) were given once a week, twice a week and 3 times a week in the treatment group 1, the treatment group 2 and the treatment group 3 respectively, 4 weeks were as one course and totally 3 courses were required in the 3 groups.

Designing high efficiency asymmetric polarization converter for blue light: a deep reinforcement learning approach.

Conventional polarization converters selectively preserve the required polarization state by absorbing, reflecting or refracting light with unwanted polarization state, leading to a theoretical transmittance limit of 0.5 for linearly polarized light with unpolarized light incidence. In the meanwhile, due to the high-dimensional structure parameters and time-consuming numerical simulations, designing a converter with satisfactory performance is extremely difficult and closely relies on human experts' experiences and manual intervention.

[Comparative study on the academic thought of bloodletting for expelling pathogens between Jin-Yuan Dynasties and Ming-Qing Dynasties].

The relevant provisions of bloodletting for expelling pathogens are collected from the works of the medical representative scholars in Jin-Yuan Dynasties and Ming-Qing Dynasties respectively to construct the databases of bloodletting for expelling pathogens of Jin-Yuan Dynasties and Ming-Qing Dynasties. Using frequency analysis, the bloodletting device, bloodletting location, bloodletting volume, the related pathogens and indications are compared between these two times so that the evidences could be provided for the inheritance and development of the academic thought of bloodletting for expelling pathogens. It is found that the three-edge needle is the most commonly used device for bloodletting in Jin-Yuan Dynasties and Ming-Qing Dynasties and meridians and local affected area are generally selected for bloodletting.

Tandem solar cells efficiency prediction and optimization deep learning.

Optical design plays an important role in improving the performance of opto-electronic devices. However, conventional design processes using finite difference time domain (FDTD) or finite element methods are usually time and computing resource consuming, and often result in sub-optimal solutions due to an incomplete search of the parameter state space. In this paper, we propose a deep learning approach to predict and optimize the cell performance of perovskite/crystalline-silicon (c-Si) tandem solar cells.

[Changes of microcirculation in superficial tissues of acupoint regions of lower leg during menstrual cycle in healthy young girls].

Objective: To observe changes of microcirculation in the superficial regions of acupoints of the three Yin meridians of foot during the menstrual cycle in young college students, so as to provide experimental evidence for explaining the saying of traditional Chinese medicine that acupoints reflect the state of physiological and pathological activities of the internal organs.

Methods: Ninety healthy female volunteer college students were recruited in the present study. The subjects were asked to take a supine position on an examination couch to expose the Yuan-primary acupoints Taixi (KI3), Taibai (SP3) and Taichong (LR3), and Xi-cleft acupoints Shuiquan (KI5), Diji (SP8) and Zhongdu (LR6) which are related to the uterus of the three Yin meridians of foot， the crossing acupoints of the three Yin meridians of foot Sanyinjiao (SP6), non-specific acupoint of the Spleen meridian Xuehai (SP10), non-related meridian acupoint Xuanzhong (GB39) and non-meridian-non-acupoint (being at the same level of GB39, between the Stomach and Gallbladder meridians on the lateral aspect of the lower leg).
