Objective To discuss the relationships between qi-arrival and mind-control, qi-arrival and qi-regulation, and to define qi-arrival by tracing the relevant records in Nei Jing (Classic of Internal Medicine) and Nan Jing (Classic of Difficult Issues). Method Thirty-seven relevant ancient books of the two classics were reviewed and the notes by WANG Bing, MA Shi, and YANG Shang-shan were referred. Result Mind-control requires the spirits of the practitioner, patient and environment, as well as observing and waiting for the arrival of qi. Regarding qi-regulation, theories involve that qi-arrival achieves same reinforcing and reducing effect as qi-regulation, qi-regulation is elucidated from the correct location of acupoint, proper needling depth and direction, and to regulate qi by observing the arrival of qi. Besides, the changes of internal and external environments also influence qi-arrival via qi-regulation and mind-control. Conclusion Qi-arrival is closely related to mind-control and qi-regulation in obtaining, differentiation, and adjustment. Mind-control and qi-regulation assist each other through the whole acupuncture process, which is the core of qi-arrival.

The expression of Attractin mRNA and protein in testis and semen of human and male mice was investigated. Human testis and semen samples were all collected from Reproductive Center of Renmin Hospital, Wuhan University in December, 2012. Testis samples were collected from 7 cases of obstructive azoospermias when they were subjected to diagnosed testis biopsy, and 30 normal human semen samples were obtained from those cases of semen analysis. Adult mice testis tissues were obtained from 10 2-month-old male BALB/c mice, and 60 male mice at different ages were classified into 10 groups (day 1, 5, 10, 15, 21, 28, 35, 42, 56, and 120 respectively, n=6 each). The expression of Attractin mRNA and protein in testis was detected by RT-PCR and Western blotting respectively. Human semen samples were centrifuged into sperm plasma (SP) and sperm extract (SE), and mice sperm samples were collected from the epididymis of 10 adult male BALB/c mice. Western blotting was used to determine the Attractin protein expression level. Attractin mRNA and protein were expressed in the testis of both patients with obstructive azoospermias and adult Bcl/B mice. Quantitative RT-PCR revealed that no Attractin mRNA was detectable in day 1 male BALB/c mice group. The Attractin mRNA and protein levels were low on the day 10, and increased with age until day 56. On the day 120, the expression levels of Attractin were decreased. As for human semen samples, Attractin protein was expressed in both SP and SE, but didn't exist in samples from the epididymis of male BALB/c mice. It was suggested that Attractin acted as a novel active substance and was involved in male reproduction in both human and BALB/c mice, but it exerted a different expression profile in different mammal species.

Tripterygium glycosides preparation which extracted from the traditional Chinese herb Tripterygium wilfordii (TWHY), was widely used to treat the autoimmune diseases. Previous works demonstrated that TWHF had potent anti-inflammatory and immunosuppressive properties. But the different quality and high incident rate of side effects of different manufactures inhibited its clinical application. Since TWHF had been generally known to play a therapeutical effect by synergism of multiple constituents, it was necessary to build the relationship between the HPLC fingerprint and bioactivity so as to ensure the quality safety and efficacy. The HPLC fingerprint showed that description and content of peaks from different manufactures were diverse. Only 11 common peaks were found. In this study, mice spleen cells stimulated by Con A were used to test the proliferation inhibition bioactivity of TWHF preparations, which were incubated with 30, 15, 7.5, 3.75, 1.88 and 0.94 mg x L(-1) TWHF preparations for 48 h. The results showed that mice spleen cells proliferation was inhibited by all TWHF preparations significantly compared with the control group, which suggested the TWHF preparations showed immune suppress activity. The TWHF preparations from 7 manufacture showed different IC50 value, which might belong to different contents which showed in the HPLC fingerprint. Moreover, a relationship between the HPLC fingerprint and the bioactivity were established to identify important constituents by grey relational analysis (GRA). The result showed that all the contents were relative with the IC50, especially No. 5 and 10 peaks, but No. 1 peak, which was proved to be triptolide, had few contribute to the inhibition of mice spleen cells proliferation. The study of relationship between the HPLC fingerprint and the IC50 by GRA could help to investigate mechanism of bioactive and provide an evidence for the quantification of multi-constituents.

Hespintor is an unknown function protein that was got from hepatoblastoma cell lines HepG2 by suppression subtractive hybridization technique (SSH), sequence analysis showed that the protein is a new member of secretory type of Kazal type serine protease inhibitor (Serpin) family, and has high homology with esophageal cancer related gene 2 (ECRG2). The coding sequence of Hespintor's Kazal domain was subcloned into prokaryotic expression vector pET-40b(+), then transformed into Rosetta (DE3). A recombinant protein about 42 kDa in the form of inclusion body was optimization expressed by inducing with 0.25 mmol/L IPTG, 30 degrees C for 5 h. and its specificity was confirmed via Western blotting. The recombinant protein was purified by metal chelate affinity chromatography (MCAC) and anion-exchange chromatography. The preliminary experimental result showed that the recombinant protein can inhibit trysin hydrolysis activity specifically. The result clearly demonstrated that Hespintor, as a novel member of Serpin, would be valuable in developing anti-tumor agents.

The antisense transcript long non-coding RNA (1ncRNA) (antisense non-coding RNA in the INK4 locus,ANRIL) is an antisense of the cyclin-dependent kinase inhibitor 2B (CDKN2B) gene on chromosome 9p21 that contains an overlapping 299-bp region and shares a bidirectional promoter with alternate open reading frame (ARF).In the context of gene regulation,ANRIL is responsible for directly recruiting polycomb group (PcG) proteins,including polycomb repressive complex-1 (PRC-1) and polycomb repressive complex-2 (PRC-2),to modify the epigenetic chrornatin state and subsequently inhibit gene expression in cis-regulation.On the other hand,previous reports have indicated that ANRIL is capable of binding to a specific site or sequence,including the Alu element,E2F transcription factor 1 (E2F1),and CCCTC-binding factor (CTCF),to achieve trans-regulation functions.In addition to its function in cell proliferation,adhesion and apoptosis,ANRIL is very closely associated with atherosclerosis-related diseases.The different transcripts and the SNPs that are related to atherosclerotic vascular diseases (ASVD-SNPs) are inextricably linked to the development and progression of atherosclerosis.Linear transcripts have been shown to be a risk factor for atherosclerosis,whereas circular transcripts are protective against atherosclerosis.Furthermore,ANRIL also acts as a component of the inflammatory pathway involved in the regulation of inflammation,which is considered to be one of the causes of atherosclerosis.Collectively,ANRIL plays an important role in the formation of atherosclerosis,and the artificial modification of ANRIL transcripts should be considered following the development of this disease.
