In order to study the development characteristics of Rehmannia glutinosa tuberous root expansion and reveal the regulation mechanism of the genes related to hormones in this process, R. glutinosa "wen-85" was used as the experimental material in this study. R. glutinosa tuberous roots of different developmental stages were collected to observe phenotype and tissue morphology using resin semi-thin sections method. The genes related to hormone biosynthesis and response were chosen from the transcriptome of R. glutinosa, which was previously constructed by our laboratory, their expression levels at different development stages were measured by real-time quantitative PCR. The results showed that the root development could be divided into six stages: seeding, elongation, pre-expanding, mid-expanding, late-expanding and maturity stage. The anatomic characteristics indicated that the fission of secondary cambium initiated the tuberous root expansion, and the continuous and rapid division of secondary cambium and accessory cambium kept the sustained and rapid expansion of tuberous root. In addition, a large number oleoplasts were observed in root on the semi-thin and ultra-thin section. The quantitative analysis suggested that the genes related to biosynthesis and response of the IAA, CK, ABA,ethylene, JA and EB were up-regulated expressed, meanwhile, GA synthesis and response genes were down-regulated expressed and the genes of GA negative regulation factors were up-regulated expressed. The maximum levels of most genes expression occurred in the elongation and pre-expansion stage, indicating these two stages were the key periods to the formation and development of tuberous roots. Oleoplasts might be the essential cytological basis for the formation and storage of the unique medicinal components in R. glutinosa. The results of the study are helpful for explanation of development and the molecular regulation mechanism of the tuberous root in R. glutinosa.

Based on leads provided by Neijing and other literature, analyze origins of the three-yin and the three-yang and the their respective contents of yin and yang, indicating the principle that the order of yang-qi from more to less is Yang ming, Tai yang, Shao yang, and the order of yin-qi is Tai yin, Shao yin, Jue yin. According to the location of five (six) zang-organs, respective yin-qi content is defined, and according to the principle of more yin-qi matches more, and less yin-qi matches less, five (six) zang-organs match each other. The zang-organs above the diaphragm joints with The Hand-Channels and the zang-organs below the diaphragm with The Foot-Channels, completing the nomenclature of twelve meridians. The names of the six yang-channels correspond to the yin-channels of the exterior-interior relationship, the yin-channels link with hands (feet), and the yang-channels also link with hands (feet), and the amount of yin-qi of the zang-organs corresponding to the yin-channels and the amount of yang-qi of the fu-organs corresponding to yang-channels are in a state of balance. Based on this principle, nomenclature of six channels are completed. Emphasize that the nomenclature of twelve meridians contains profound TCM theories, especially, TCM, by yin-yang, three-yin and three- yang, illustrates living phenomena from the whole to the system and organ level in human body, and the scientific principle "yin-yang can be unlimitedly divided" and its significance, which must guide the studies on living phenomena with modern life sciences from the whole to the molecular level.

OBJECTIVETo explore the prediction of the site for microsurgical vasoepididymostomy (VE) in the treatment of epididymal obstructive azoospermia (OA).
METHODSThis study involved 56 infertile men with confirmed OA whose obstruction was suspected to be in the epididymis. Based on their medical history and results of preoperative physical examination and ultrasonography, we predicted the sites for VE. We performed surgical scrotal exploration for the status of epididymal obstruction, conducted palpation and microscopic observation for the epididymal tubules to be anastomosed, and finally decided on the sites for VE by making sure of the presence of motile sperm in the epididymal fluid of the patients. After surgery, we followed up the patients for the rate of pregnancy.
RESULTSAll the patients received bilateral scrotal ultrasonography and surgical scrotal exploration, totaling 112 procedures, including 98 VE procedures. The accuracy rate of the predicted sites for VE was 80.5% (153/190) by medical history and physical examination, 80.3% (90/112) based on the results of ultrasonography, and 87.4% (90/103) according to the first selected epididymal tubules. Of the 28 patients followed up for more than 12 months, motile sperm were found in 19 (67.9% ) at 2 to 12 months and spontaneous pregnancies were achieved in 10 (35.7%), all with the anastomotic sites in the corpus or cauda.
CONCLUSIONMedical history and physical examination contribute to the selection of anastomotic sites and non-invasive scrotal ultrasonography is effective and practical for positioning epididymal obstruction. The epididymal tubules with motile sperm for anastomosis could be easily obtained from the most dilated ones in indurated epididymides.
