OBJECTIVETo explore the performance patterns of reaction point Jingtong in balance acupuncture through multi-center and big-sample clinical investigation. Methods The Jingtong points of balance acupuncture on healthy side and affected side were observed among 230 cases of cervical spondylosis and scores of self-discomfort in reaction point, color of skin, changes of skin, morphology of subcutaneous tissue and abnormal pressing pain were recorded. The software SPSS 15.0 was applied to statistically analyze the recorded scores.
RESULTSAmong 230 cases, the reaction point appeared in 226 cases, accounting for 98. 3%. Among the 226 cases who had reaction point, the total score of symptom and sign was (1.08+/-1.09) on the healthy side and (0. 84+/-1. 36) on the affected side, which had statistical significance (P<0. 01); score of self-discomfort in reaction point was (0. 76 +/-0. 83) on the healthy side and (0. 40+/-0.80) on the affected side, which had statistical significance (P<0.01); the score of skin color was (0.10+/-0.36) on the healthy side and (0. 03+/- 0. 19) on the affected side, which had statistical significance (P<0. 05); the score of abnormal pressing pain was (2. 47+/-2. 46) on the healthy side and (1. 39+/-2. 37) on the affected side, which had statistical significance (P<0. 01).
CONCLUSIONThe total score of symptom and sign of reaction point Jingtong on the healthy side is higher than that on the affected side, indicating positive reaction of Jingtong on the healthy side has specificity for cervical spondylosis. When patient has cervical spondylosis on either side of neck, the other side will have anomaly in Jingtong.

OBJECTIVETo observe the effect of Schisandra chinensis lignans (SCL) on neuronal apoptosis and PI3K/AKT signaling pathway of rats in the cerebral ischemia injury model, and study its possible mechanism.
METHODRats were orally administered SCL high, middle and low dose groups (100, 50, 25 mg x kg(-1)) for 14 days. The cerebral ischemia injury model was established by using the suture-occluded method to rate the neurological functions. The cerebral infarction area was observed by TTC staining. The pathological changes in brain tissues were determined by HE staining. Bcl-2 and Bax expressions were detected by immunohistochemical assay. The protein expressions of p-AKT and AKT were assayed by Western blotting.
RESULTCompared with the model group, SCL high, middle and low dose groups showed reduction in the cerebral infarction area to varying degrees, improve the pathological changes in brain tissues, promote the expression of apoptin Bcl-2 and p-AKT, and inhibit the expression of apoptin Bax.
CONCLUSIONSCL shows a protective effect on rats with cerebral ischemia injury. Its mechanism may be related to the increase in p-AKT ability and antiischemic brain injury capacity and the inhibition of nerve cells.

OBJECTIVETo assess the short-term outcomes of staged hybrid coronary revascularization performed using robotic-assisted off-pump coronary bypass grafting followed by percutaneous coronary intervention (PCI) in a non-left anterior descending (LAD) coronary artery lesion.
METHODSFrom January, 2007 to May, 2013, 35 patients (32 male and 3 female patients, mean age 56.7 ± 9.6 years) underwent staged hybrid coronary revascularization. Ten patients had double-vessel and 25 patients had triple-vessel coronary diseases, and the lesions involved an average of 2.7 ± 0.5 coronary vessels. Coronary artery bypass grafting was completed in robotic-assisted left internal thoracic artery (ITA) harvesting and LITA to LAD bypass. Coronary angiography or 64-MSCT was performed to evaluate the patency of the ITA and stents at 6 months and at 1 to 5 years postoperatively. The patients were followed for major adverse cardiac events (MACE) including cardiac death, acute myocardial infarction and target lesion revascularization.
RESULTSStaged hybrid revascularization was completed successfully in all the patients without complications. The LITA to LAD anastomosis was completed in minimally invasive direct coronary bypass grafting (MIDCAB) or totally robotic coronary bypass grafting on beating heart (TECAB) with the assistance of da Vinci Surgical System. The mean artery graft flow was 36.0 ± 22.5 ml/min, and the graft had a 100% patency before discharge. A total of 49 stents were deployed in 35 patients within 2 weeks after robotic coronary bypass grafting, with a mean of 1.34 ± 0.6 stents per case (1 stent in 23 cases, 2 stents in 11 cases, and 3 stents in 1 case). The patients were followed up for 17.5 ± 11.6 months, and 1 patient had artery graft occlusion and another had in-stent occlusion at 6 months. All the other 33 patients had patent LITA-to-LAD anastomosis without angina or MACE.
CONCLUSIONStaged hybrid revascularization strategy has acceptable angiographic patency results for both LITA-LAD grafts and PCI interventions.

The changes of microRNA expression in rat hippocampus after traumatic brain injury (TBI) were explored. Adult SD rats received a single controlled cortical impact injury, and the ipsilateral hippocampus was harvested for the subsequent microarray assay at three time points after TBI: 1st day, 3rd day and 5th day, respectively. We characterized the microRNA expression profile in rat hippocampus using the microRNA microarray analysis, and further verified microarray results of miR-142-3p and miR-221 using quantitative real-time PCR. Totally 205 microRNAs were identified and up-/down-regulated more than 1.5 times. There were significant changes in 17 microRNAs at all three time points post-TBI. The quantitative real-time PCR results of miR-142-3p and miR-221 indicated good consistency with the results of the microarray method. MicroRNAs altered at different time points post-TBI. MiR-142-3p and miR-221 may be used as potentially biological markers for TBI assessment in forensic practice.

OBJECTIVETo study the role of flow cytometry (FCM) in detection of polymorphic post-transplant lymphoproliferative disorders (PTLD).
METHODS AND RESULTSTwo patients presented with fever and multiple lymphadenopathy on day 46 and day 50 respectively after successful allogeneic hematopoietic stem cell transplantation (allo-HSCT). The symptoms couldn't be controlled by antibiotics. The polymorphic PTLD was diagnosed based on the elevation of bone marrow EB virus DNA and detection of subsets of light chain restricted B cells and/or plasma cells in peripheral blood (PB) samples. The lymphocyte immunophenotypes from PB and/or bone marrow (BM) samples were serially tested by FCM after lowering the dose of immunosupressive agents and treating with antivirus drugs, anti-CD20 antibodies, and cytotoxic T cell infusion. B cells were undetable in two patient, but monoclonal plasma cells appeared or maintained. One patient died after two weeks. Another patient was still on treatment. B cells and plasms cells couldn't be detected in her PB, but there were monoclonal plasma cells in her BM. FCM have a prominent advantage in detect polymorphic PTLD, since it can effectively recognize different cell groups in blood and identify monoclonal subsets. Besides, the immunophenotype of plasma cells in polymorphic PTLD might be different from that in typical plasma cell myeloma.
CONCLUSIONPolymorphic PTLD can be detected and followed up by FCM. BM is more suitable than PB for monitoing the disease. Besides lymph node biopsy, B cell abnormaliity could be detected in PB in allo-HSCT patients.

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 discuss the application of medial planta island flaps pedicled with anterior tibial artery perforator in front of inner malleolus for repairing small wounds around ankle.
METHODSFrom Jan. 2005 to Jun. 2009, 10 cases with small wounds around ankle were treated with medial planta island flaps pedicled with anterior tibial artery perforator. The flap size ranged from 7.5 cm x 2.8 cm to 13.0 cm x 5.0 cm. The wounds at the donor sites were covered with skin grafts.
RESULTSAll the 10 flaps and skin grafts were survived with primary healing. The patients were followed up for 6-12 months with satisfactory cosmetic results. The 2-point discrimination was 4-6 mm when the proximal end of saphenous nerve was not injured, and it was 9-10 mm when the nerve was injured or cut off. The patients could walk with no occurrence of ulcer in flaps or donor site.
CONCLUSIONSThe medial planta island flaps pedicled with anterior tibial artery perforator can effectively repair the small wounds around ankle with reliable blood supply.
