Shaanxi has a long history and profound cultural heritage. It has been referred to as “Qin” for a long time in history. Shaanxi is rich in medicinal plant resources, various main Chinese medicines such as Fraxini cortex, Gentianae Macrophyllae Radix, Ten “Qin medicine” (Astragali Radix in Zizhou County, Bupleuri Radix in Baoji, Corydalis Rhizoma in Yang County, Salviae Miltiorrhizae Radix et Rhizoma in Shangluo, Aconiti Lateralis Radix Praeparata in Hanzhong; Eucommiae Cortex in lueyang County; Gastrodiae Rhizoma in Ningshan County; Polyporus in Ningshan County; Scutellariae Radix in Chengcheng County; Corni Fructus in Foping County; Polygonati Rhizoma in Lueyang County) and “Taibaiqi medicine” are typically species of “Qin medicine”. In history, “Qin medicine” represents genuine medicinal materials produced from Shaanxi Province and the surrounding region. In recently, the industry of “Qin medicine” becomes one of the most valuable resources in Shaanxi, which also contributes to the integral part of Chinese medical and health services. Here, the research progress on germplasm resources, cultivation techniques, plantation base construction, variety breeding, bioactive compounds, and quality control of “Qin medicine” were integrated and reviewed, and its future development of “Qin medicine” was also prospected.

Mitogen-activated protein kinases (MAPKs) are important signaling transduction components well conserved in eukaryotes and play essential roles in various physiological, developmental and hormonal responses in plant. In the present study, a MAPK gene, designated as DoMPK4 (GenBank accession No. JX297597), is identified from a rare endangered medicinal orchid species D. officinale using the reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods. The full length cDNA of DoMPK4 is 1 518 bp in length and encoded a 369 aa protein with a molecular weight of 42.42 kD and an isoelectric point of 5.55. DoMPK4 protein contained a serine/threonine protein kinase active site (158-170), a MAP kinase site (71-174), and eight conserved motifs. DoMPK4 had a transmembrane (214-232) but no signal peptide. Multiple sequence alignment showed that DoMPK4 shared high identities (74.9%-80.6%) with MAPK proteins from various plants. Phylogenetic analysis demonstrated that DoMPK4 belonged to group A of the MAPK evolutionary tree, and is closely related to monocots. Real time quantitative PCR (qPCR) analysis revealed that DoMPK4 is differentially expressed among the five organs including leaf, stem, root, seed, and protocorm-like body (PLB). The transcription level of DoMPK4 is the highest in the PLBs with 17.65 fold, followed by seeds, roots, and stems with 5.84, 2.28, and 1.64 fold, respectively. The progressive enhancement of DoMPK4 transcripts in the developing PLBs compared to that in the germinating seeds, suggests a role of DoMPK4 during the development of embryogenic PLBs formation in D. officinale.

OBJECTIVETo study the relaxant effect of ethanol on the isolated rabbit corpus cavernosum and its possible mechanism.

METHODSThe tension of isolated smooth muscle strips was recorded by the platform physiological graphed, and the concentrations of cAMP and cGMP in the rabbit corpus cavernosum were measured by 125I radioimmunoassay.

RESULTSThe 1.25% (V/V) ethanol significantly augmented the corporal relaxation induced by isoprenaline (10(-9) - 10(-5) mol/L). Ethanol-induced relaxation was inhibited by 100 micromol/L and 300 micromol/L SQ22536 (an adenylate cyclase inhibitor). Emax was depressed from (105.12 +/- 3.39) % to (97.00 +/- 2.57) % in the presence of 100 micromol/L SQ22536 or (91.09 +/- 2.42) % in the presence of 300 micromol/L SQ22536. EC50 was increased from (1.18 +/- 0.09)% (V/V) to (1.36 +/- 0.10) % in the presence of 100 micromol/L SQ22536 (P < 0.05) or (1.68 +/- 0.13) % (in the presence of 300 micromol/L SQ22536) (P < 0.05) respectively. Ethanol significantly elevated the level of cAMP but not that of cGMP in the isolated rabbit corpus cavernosum, and it also significantly enhanced the activity of the adenylate cyclase (AC) extracted from the rabbit corpus cavernosum in a dose-dependent manner.

CONCLUSIONEthanol has a relaxant effect on the isolated rabbit corpus cavernosum, which may be associated with the cAMP signaling pathway.

OBJECTIVETo further investigate the action mechanisms of berberine (Ber), and assess the effects of Ber on the in vitro formation of cGMP and cAMP in the isolated rabbit corpus cavernosum.

METHODSIsolated segments of the rabbit corpus cavernosum were exposed to different concentrations of Ber, and, the dosage-dependent accumulations of cGMP and cAMP were determined in the tissue samples by means of 125I radioimmunoassay. Responses of the isolated tissue preparations to Ber were compared with those obtained with the reference compound sildenafil (Sil).

RESULTSBer increased cGMP concentrations directly (P < 0.05). In the presence of sodium nitroprusside (SNP), a stimulatory agent of cGMP, both Ber and Sil increased cGMP with increasing dosage (P < 0.01), the EC, values being 1.32 and 0.67 micromol/L respectively. With the same concentration, neither Ber nor Sil influenced the cAMP level significantly (P > 0.05). In the presence of PGE1, a stimulator of cAMP, Ber and Sil also raised the cAMP level concentration (P < 0.01 ), the EC, values being 4.90 (Ber) and 6.53 (Sil) micromol/L respectively.

CONCLUSIONBer can increase cGMP and cAMP concentrations in the corpus cavernosum smooth muscles, which may contribute to its action of relaxing corpus cavernosum smooth muscles.

Methods A total of 1801 elderly people aged 60 to 79 years old from six districts of Zhoushan City were sampled by method of stratified random sampling. After self-evaluated with Ascertain Dementia 8 (AD8) and screened with Screening Scale for Mild Cognitive Impairment (sMCI), the diagnosis by specialists was conducted for that positive to AD8 and sMCI. Results of 1801 respondents, 873 (48.47％) people were male, and the other 928 (51.53％) people were female; 38.65％ of the people selected aged 60-<65; 90.28％ had a primary school education or were illiterate; 78.51％ had legitimate and healthy wives. A total of 122 elderly people were diagnosed with MCI, and the prevalence of MCI was 6.77％. Multivariate logistic regression analysis showed that male elderly people (OR=0.53, 95％CI:0.28-1.00) were less likely to develop MCI compared to the female, and the illiterate (OR=2.09, 95％CI: 1.16-3.77) were more likely to develop MCI compared to the educated . Conclusion The prevalence of MCI among the elderly in Zhoushan was 6.77％; the female and the illiterate were more likely to develop MCI.

The present study utilized LC-MS and HPLC approaches to characterize the metabolites of neferine in rat liver after an oral administration of 20 mg x kg(-1), and investigated the involvement of CYP450 isoforms in the metabolism of neferine by their selective inhibitors in vitro, separately. In positive ionization mode, besides neferine, four metabolites (M1-M4) were detected. M2 (the major metabolite) and M4 were identified as liensinine and isoliensinine by comparison with reference substances. Moreover, according to the analysis of metabolic rule of parent drug (neferine), M1 and M3 may be desmethylliensinine and desmethyl-isoliensinine, respectively. Furthermore, the metabolism of neferine in rat liver microsomes showed that the percentage inhibition of the major metabolism (liensinine) formation was 80.5% by quinidine (10 micromol x L(-1), selective CYP2D1 inhibitor) and 25.7% by ketoconazole (1 micromol x L(-1), selective CYP3A1 inhibitor). Neferine was mainly metabolized by CYP2D1 or CYP3A1 to liensinine, isoliensinine, desmethyl-liensinine and desmethyl-isoliensinine.

OBJECTIVETo evaluate the clinical value of activated carbon nanoparticles for guiding lymphadenectomy in lung cancer.

METHODSFourty-two lung cancer patients were divided into two groups: the control group (22 cases) and experiment group (20 cases) who received activated carbon nanoparticles injection around the tumor either by endoscopic injection or intraoperative subserosal injection. The number of dissected lymph node, black-stained lymph node, positive lymph node and the side effect of the procedure were analyzed, respectively.

RESULTSNo severe complication was observed in the experiment group. The operative time was not prolonged significantly in the experiment group either. However, the number of average lymph nodes dissected in the experiment group (25.5) was significantly more than that in the control group (14.6) (P <0.01).

CONCLUSIONLocal injection of activated carbon nanoparticles around the tumor during surgical exploration is effective, safe and easy to do for guiding lymphadenectomy in lung cancer patient.

AIMTo explore the effects of lipoteichoic acid (LTA) induced delayed preconditioning (PC) on hypoxia-reoxygenation (H/R) injury of cultured human coronary artery endothelial cells (HCAECs), and to investigate the potential role of endogenous nitric oxide (NO) participated in the protective mechanism.

METHODSHCAECs were incubated for 2 h in a hypoxic atmosphere and reoxygenated for 4 h in a normoxic atmosphere. The delayed PC was induced by pretreatment with LTA (30 or 300 microg x L(-1)) for 4 h before 24 h recovery. The extent of cellular injury after reoxygenation was assessed by the percentage of cellular injury with Trypan blue exclusion and by the amount of lactate dehydrogenase (LDH) in culture media. The NO level of the culture media was measured spectrophotometrically. Furthermore, HCAECs were exposed to 300 microg x L(-1) of LTA for 4 h, and to detect the expression of eNOS mRNA by RT-PCR method after cells were recovered from different points.

RESULTSLTA pretreatment significantly decreased the percentage of the killed cell and the concentration of LDH in media. Also, LTA pretreatment obviously raised the concentrations of NO in culture media. The protective effects of LTA were abrogated by pretreatment with N-monomethyl-L-arginine (L-NMMA). Moreover, the expression of eNOS mRNA was significantly upregulated after HCAECs exposure to LTA for 4 h following 2 h or 4 h recovery.

CONCLUSIONLTA could induce the delayed protection against H/R induced endothelial injury and dysfunction of cultured HCAECs. NO produced by eNOS acts initially as a trigger and subsequently as a mediator of delayed PC.
