RESUMEN
The theory of "tian-yin-yang" of Zhuang medicine was explored and the academic achievements and experience of professor HUANG Jin-ming were summarized to explain the theory and clinical characteristics of tian-yin-yang acupuncture, an acupuncture school of Huang 's Zhuang medicine of Guangxi. This acupuncture method is guided by the theory of "three-qi synchronization" and "tian-yin-yang" of Zhuang medicine, based on the theory of "three channels and two paths", with regulating qi as the method and regulating spirit as the basis. After the patient is calmed and resting, the micro needle shallow needling technique is adopted, mainly at the umbilical ring point, so as to achieve the purpose of regulating the mind and treating the root cause.

The fertilization capacity of sex-sorted sperms is seriously decreased, which inhibits its wide application. However, little information is still available about the effect of vitamin C (VC) and lycopene (Lyc) on the fertilization capacity of sex-sorted bull sperm. In this study, the washing medium and fertilization medium of sex-sorted sperm from three bull individuals were supplemented with different concentrations of VC (0, 1 × 10-3 , 1 × 10-4 , 1 × 10-5 , 1 × 10-6 M) or Lyc (0, 1 × 10-4 , 1 × 10-5 , 1 × 10-6 , 1 × 10-7 ). After washing twice and incubation for 1.5 hr, the malondialdehyde (MDA) level, phosphatidylserine (PS) translocation, membrane potential (Δψm) and IVF (in vitro fertilization) ability of sex-sorted sperm were investigated. For the sex-sorted sperm of bulls A, B and C, 1 × 10-3 M VC or 1 × 10-4 M Lyc treatment significantly decreased their MDA levels and PS translocation and increased their Δψm levels and cleavage rates after IVF. When blastocysts were concerned, 1 × 10-4 M Lyc significantly improved the blastocyst rates and their IFN-tau expression of bulls A and C. In conclusion, supplementation of 1 × 10-3 M VC or 1 × 10-4 M Lyc in washing and fertilization medium contributed greatly to improving the fertilization capacity of sex-sorted bull sperm during IVF procedure.

Little information is available regarding the effect of melatonin on the quality and fertilization capability of sex-sorted bull sperm, and even less about the associated mechanism. Sex-sorted sperm from three individual bulls were washed twice in wash medium and incubated in a fertilization medium for 1.5 h, and each was supplemented with melatonin (0, 10-3 M, 10-5 M, 10-7 M, and 10-9 M). The reactive oxygen species (ROS) and endogenous antioxidant activity (glutathione peroxidase (GPx); superoxide dismutase (SOD); catalase (CAT)), apoptosis (phosphatidylserine [PS] externalization; mitochondrial membrane potential (Δψm)), acrosomal integrity events (malondialdehyde (MDA) level; acrosomal integrity), capacitation (calcium ion [Ca2+]i level; cyclic adenosine monophosphate (cAMP); capacitation level), and fertilization ability of the sperm were assessed. Melatonin receptor 1 (MT1) and 2 (MT2) expression were examined to investigate the involvement of melatonin receptors on sex-sorted bull sperm capacitation. Our results show that treatment with 10-5 M melatonin significantly decreased the ROS level and increased the GPx, SOD, and CAT activities of sex-sorted bull sperm, which inhibited PS externalization and MDA levels, and improved Δψm, acrosomal integrity, and fertilization ability. Further experiments showed that melatonin regulates sperm capacitation via MT1. These findings contribute to improving the fertilization capacity of sex-sorted bull sperm and exploring the associated mechanism.

The aim of this study was to test the effects of five different concentrations (0, 10-3, 10-4, 10-5, and 10-6 M) of resveratrol (Res) supplementation in bull sperm washing and fertilisation medium on levels of reactive oxygen species (ROS), phosphatidylserine (PS) externalisation, mitochondrial membrane potential (Δψm), ATP and malondialdehyde (MDA), acrosomal integrity, blastocyst rate, and blastocyst quality after in vitro fertilisation (IVF). The results for sex-sorted sperm from three bulls showed: (1) ROS and MDA levels in 10-3 M and 10-4 M Res groups were significantly lower than those of controls (P < 0.05); (2) the percentage of viable sperm, percentage of sperm with high Δψm, and the ATP content in 10-3 M and 10-4 M Res groups were significantly higher than those of controls (P < 0.05); (3) the percentage of viable sperm with acrosomal integrity, and the blastocyst percentage and quality of the 10-4 M Res group were significantly higher than those of controls (P < 0.05). In conclusion, 10-4 M Res supplementation in washing and fertilisation medium of sex-sorted bull sperm significantly decreased ROS, PS externalisation, and MDA, and protected mitochondrial function and acrosomal integrity, thereby increasing blastocyst percentage and quality following IVF.

The theoretical basis, location, belonging of zang-fu, treatment function and indications, applying principle and manipulation of Umbilical Ring acupoints in Zhuang medicine are explained in this paper. According to Zhuang medicine, umbilicus is an epitome of the body and all the zang-fu and organs in the body have corresponding epitomes like a fetus in front-standing position. The umbilicus is not only a micro-diagnosis system, but also a window for illness treatment that could be divided into superficial, middle and deep layer to respectively communicate different zang-fu and organs. The umbilical inner ring and outer ring are collectively called Umbilical Ring acupoints, they could dredge paths, regulate the balance of qi and blood to regulate qi, expel poison, tonify deficiency and remove stasis to treat many types of diseases in the whole body.
