ABSTRACT
The chemical and biologically active characterization of jujube samples (fruits, cores, and leaves) were carried out by the integrated nontargeted metabolomics and bioassay. Firstly, collision cross-section values of active compounds in jujubes were determined by ultrahigh-performance liquid chromatography coupled with ion mobility quadrupole time-of-flight mass spectrometry. Then, a multidimensional statistical analysis that contained principal component analysis, partial least squares-discriminant analysis and hierarchical clustering analysis was employed to effectively cluster different tissues and types of jujubes, making identification more scientific. Furthermore, angiotensin-converting enzyme (ACE) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) were used to evaluate the quality of jujubes from a double activity dimension. The analytical results obtained by using ACE and DPPH to evaluate the quality of jujube were different from multivariate statistics, providing a reference for the application of jujube. Therefore, integrating chemical and biological perspectives to evaluate the quality of jujube provided a more comprehensive evaluation and effective reference for clinical needs.

The consecutive monoculture obstacle is a major problem in the field of Rehmannia glutinosa( R. glutinosa),has severely declined the yield and quality of R. glutinosa. Here,using hi TAIL-PCR and RACE techniques,we have cloned the full-length transcript( 1 573 bp) of Unigene 29334_All screened by DGE as a consecutive monoculture obstacle response gene of R. glutinosa. Based on ORF Finder prediction,all ORFs detected in the full-length transcript were less than 300 nt,which suggested that the above transcript was confirmed to be a long non-coding RNA( LncRNA). With alignment in R. glutinosa transcriptome,this LncRNA was partially homologous to alanine glyoxylate transaminase 2 gene( Rg AGT2),which was named LncRNA-RgATG2. To further explore the function of LncRNA-RgAGT2,we have examined expression patterns of LncRNA-RgAGT2 and Rg AGT2 at five critical development stages( seedling,elongation,pre-expanding,mid-expanding,late-expanding) in the first and second year replanting of R. glutinosa,respectively. The results indicated that LncRNA-RgAGT2,as a potential regulator,is possible to play a vital role in Rg AGT2 expression regulation. Meanwhile,LncRNA-RgAGT2 has presented significant variation in all development stages of R. glutinosa,which could be used as a " diagnostic label" to assess consecutive monoculture obstacle. This study,for the first time,showed that LncRNA was responsible for the response and regulation of consecutive monoculture obstacle,which would be a powerful supplement to reveal the molecular mechanisms of consecutive monoculture obstacle of R. glutinosa.

OBJECTIVE: To observe the effect of acupotomy lysis at acupoints around the neck on expression of matrix metalloproteinase 1 (MMP-1), MMP-2 and tissue inhibitor of metalloproteinase 1 (TIMP-1) genes and ultrastructure of pulpiform nucleus in cervical intervertebral disc degeneration (IVDD) rats, so as to explore its mechanism underlying easing IVDD. METHODS: SD rats were randomly allocated to control (n = 15), model (n = 14), Jiaji (EX-B 2, n = 13), cervico-acupoint (n = 14) and medication groups (n = 14). The cervical IVDD model was established by using static-dynamic imbalance method. For rats of the Jiaji (EX-B 2) and cervico-acupoint groups, EX-B 2-points of the cervical 2-7 segments, and peri-cervical acupoints: bilateral "Naokong" (GB 19) , "Naohu" (GV 17), "Dazhui" (GV 14), bilateral "Quyuan" (SI 13) and bilateral "Tianzong" (SI 11) were separately punctured with a needle-knife, once every 5 days for 3 times, and for rats of the medication group, Brufen Capsules (15 mg · kg(-1) · d(-1)) and Jingfukang Granule (0.5 mg · kg(-1) · d(-1)) were given by intragastric administration, once daily for 10 days. The expression levels of MMP-1, MMP-3 and TIMP-1 genes in the pulpiform nucleus of cervical intervertebral discs were detected by RT-PCR and changes of the ultrastructure of the pulpiform nucleus observed under transmission electron microscope. RESULTS: Compared to the control group, the expression levels of MMP-1 mRNA and MMP-3 mRNA of the cervical intervertebral disc tissues were significantly up-regulated in the model group (P < 0.05), and that of TIMP-1 mRNA was obviously down-regulated in the model group (P < 0.05). After the treatment, the increased expression of MMP-1 mRNA and MMP-3 mRNA and the decreased expression of TIMP-1 mRNA were reversed by acupotomy lysis and medication (P < 0.05) except TIMP-1 mRNA in the medication group (P > 0.05). No significant differences were found between the Jiaji (EX-B 2) and cervico-acupoint groups in down-regulating MMP-1 mRNA and MMP-3 mRNA expression and up-regulating TIMP-1 mRNA expression (P > 0.05). Results of electron microscope examinations showed that the ultrastructural injury changes of cells of the pulpiform nucleus were relatively milder in the Jiaji (EX-B 2) and cervico-acupoint groups, followed by the medication group in comparison with those of the model group. CONCLUSION: Acupotomy lysis at acupoints around the neck can improve the ultrastructural changes of cells of the pulpiform nucleus of cervical intervertebral discs in IVDD rats, which is possibly by regulating the expression of MMP-1, MMP-3 and TIMP-1 genes.

OBJECTIVE: To observe the effect of acupotome relaxing at cervical acupoints on type I and II collagens of degenerated cervical intervertebral discs in rats, so as to explore its potential mechanism underlying anti-degeneration of intervertebral discs. METHODS: Rats were randomly divided into control, model, Jiaji acupoints, cervical acupoints and medication groups (n = 15 in each group). The rat model of cervical intervertebral disc degeneration due to static-dynamic imbalance was made as previously specified. The Jiaji acupoints were those located along the cervical vertebra 2-7. The cervical acupoints included bilateral "Naokong"(GB 19) , "Naohu" (GV 17) , "Dazhui"(GV 14) , bilateral "Quyuan" (SI 13) and bilateral "Tianzong" (SI 11). Acupoints were treated according to the procedures of acupotome for 3 times in ten days with five days' break between every two treatment sessions. Rats of the medication group were intragastrically administered with Jing Fu Kang Granules and ibuprofen daily for ten days. Twenty days after the end of treatment, all rats were sacrificed for further examination of morphological changes of the intervertebral disc tissue. Immunoactivity of protein and mRNA expression levels of collagen type I and II of the intervertebral discs were measured by means of immunohistochemistry and RT-PCR, respectively. RESULTS: In comparison with the control group, the immunoactivity and mRNA expression levels of collagen type I and II of the intervertebral discs were significantly elevated or reduced in rats of the model group, respectively (P < 0.05). After acupotome intervention and medication, the increased and decreased expression levels of type I and II collagen proteins and genes were markedly reversed (P < 0.05). The effects of acupotome relaxing of both cervical and Jiaji acupoints were significantly superior to those of medication in down-regulating expression of type I collagen protein and mRNA, and in up-regulating that of type II collagen protein and mRNA (P < 0.05). No significant differences were found between the cervical acupoints and Jiaji acupoints groups in the above- mentioned outcomes (P > 0.05) . The degree of severity of the degenerated intervertebral discs was the worst in the model group, followed by the medication group, then the Jiaji acupoints group and cervical acupoints group, and the control group the least. CONCLUSION: Acupotome at neck acupoints can regulate the extracellular matrix of the intervertebral disc via inhibiting the transformation between type I and type II collagens, which may contribute to its effect in delaying the degenerative process of the cervical intervertebral discs.

OBJECTIVE: To observe the influence of acupuncture intervention on expression of protein kinase A (PKAP in the cerebrocortex of rats with focal cerebral ischemia-reperfusion injury(CI/RI), so as to explore its underlying neuroprotection mechanism on cerebral ischemia. METHODS: Ninety male SD rats were randomly and evenly divided into sham-operation (sham), model and acupuncture groups which were further randomized into 3, 7 and 14-days (d) subgroups (10 rats/subgroup). CI/RI model was established by occlusion of the left middle cerebral artery for 2 hours and reperfusion. Manual acupuncture stimulation was applied to "Baihui" (GV 20) and "Shuigou" (GV 26), as well as the right "Quchi" (LI 11), "Hegu" (LI 4), "Neig (PC 6), "Zusanli" (ST 36),"Sanyinjiao"(SP 6) and "Taichong" (LR 3) for 30 min, once daily for 3, 7 and 14 d respectively. Rats of the sham and model groups were restrained for 30 min each day. Neurological defects were assessed by ethologic scoring according to Bederson's neurologic assessment scales. Cellular apoptosis in the ischemic cortex was detected by flow cytometry and PKA expression determined by immunohistochemistry for calculating its PKA immunoreaction (IR)-positive cell rate, respectively. RESULTS: Compared with the sham group, the neurologic scores, cortical cellular apoptosis rates and PKA IR-positive cell rates of the model group were significantly increased at the time-points of day 3, 7 and 14 post-treatment (P<0. 05). In comparison with the model group, the neurologic scores and cortical cellular apoptosis rates of the acupuncture group at the time-points of day 3, 7 and 14 post-treatment were considerably down-regulated (P<0. 05), and the cortical PKA IR-positive cell rates of the acupuncture group were remarkably increased (P<0. 05). In addition, along with the increase of acupuncture treatment sessions, lower apoptosis rates and more PKA IR-positive cells were found, suggesting a cumulative effect. CONCLUSION: Acupuncture intervention can lower cellular apoptosis rate of the ischemic cerebrocortex and up-regulate cortical PKA expression level in CI/RI rats, which may be responsible for its effect in improving neurologic deficits.
