Abundant experiences have already been accumulated in treatment of stroke with acupuncture. Development of rehabilitation theory also brings unprecedented opportunity and challenge to acupuncture. Combined with the modern rehabilitation theory and practice, it is very helpful to deepen the understanding on treatment of acupuncture for cerebral apoplexy and enhance the therapeutic effect in clinic by studying the mechanism of acupuncture treatment, opportunity of intervention, selection of acupoints, needling manipulations and quantity of stimulations etc. Through analysis on the necessity and the way of combination of acupuncture and modern rehabilitation, it is concluded that rehabilitation evaluation, rehabilitation phases and obstacle analysis should be taken as references by acupuncturists to reinforce the therapeutic effect and creditability of acupuncture treatment on cerebral apoplexy.

Cell therapy has a very promising potential for end-stage liver diseases (ESLD).Fetal liver stem/progenitor cells (FLSPCs) have advantages of safety,high survival and proliferation rates,and a small volume,all which make them ideal for liver disease stem cell therapy.During the early phase of our study,we applied a three-step separation method to enrich FLSPCs and obtained a separation efficiency similar to that of the flow-cell sorting method.Additionally,using a fulminant hepatic failure model in rats,we have demonstrated that FLSPCs can contribute to morphological and functional recovery of the liver.This manuscript will discuss how FLSPCs can be induced to accurately differentiate into hepatocytes and cholangiocytes and how FLSPCs maintain self-renewal.The Notch signaling plays a critical role in regulating the differentiation and self-renewal of many types of stem cells.Our previous findings have shown that the Notch signaling plays an important role in FLSPCs differentiation into hepatocytes.Therefore,the Notch signaling might be involved in the differentiation and self-renewal of FLSPCs.We conducted a study on the regulatory effects and relative molecular mechanisms of the Notch signaling on FLSPCs and found the corresponding interfering target,which might become an index for the clinical application of FLSPCs.

Objective To synthesize 628F-Py-AMD3465,to investigate its biodistribution in mice and to perform the microPET/CT imaging on mice bearing human lung cancer cell (A549).Methods AMD3465 quaternary ammonium salt precursor was directly labeled with 18F,then 628F-Py-AMD3465 was synthesized through nucleophilic reaction,hydrolysis,neutralization and the product was purified using HPLC.The labeling yield and radiochemical purity were analyzed by HPLC.Fifteen Kunming mice were injected with 5.55 MBq of 628F-Py-AMD3465 and sacrificed at 5,20,40,60 and 120 min postinjection.The selected tissues were harvested and weighed,and the radioactivity in the tissues was measured by an automated γ-spectrometer.The ％ID/g was calculated.MicroPET/CT studies were performed on A549-bearing mice after injecting 6-18F-Py-AMD3465 through vena caudal.Paired t test was used.Results 6-18F-Py-AMD3465 was successfully synthesized with the labeling yield of (9.0±2.0)％,the total synthesis time was about 60 min,and the radiochemical purity was more than 98％.Biodistribution studies showed that the radiouptake was higher in the kidneys and bladder of normal mice,which demonstrated that 6-18 F-Py-AMD3465 was mainly excreted through the kidneys.Biodistribution in A549-bearing mice was similar to that in normal mice.The tumor/muscle ratio at 40 min was 5.0,but the radiouptake of the tumor was still lower than that of the normal lung:(8.05±0.35) ％ID/g vs (9.33±0.66) ％ID/g;t=5.26,P＜0.05.MicroPET/CT imaging showed that the high-uptake location of 6-18F-Py-AMD3465 in tumor-bearing mice was similar to the normal mice,and the tumor uptake reached the maximum level at 45 min post-injection (SUV 0.67).Conclusions 6-18F-Py-AMD3465 can be synthesized by a simple method.A lower uptake could be shown in the tumor compared to that in the lung and the tracer has limited diagnostic value for lung cancer.

Litsea glutinosa, belonging to family Lauraceae, is widely distributed in subtropical and tropical regions. L. glutinosa was used to cure many diseases as folk medicine in China. It has proved that the plant showed anti-diabetic, anti-inflammatory, and anti-bacterial activities. So far, more than 50 compounds including flavonoids, alkaloids, and lignans have been isolated from this plant. Alkaloids were deemed as its characteristic constituents. This review summarized the biological activities and chemical constituents of L. glutinosa for the first time. Based on these collected information, we pointed out that little information was found related to the potential mechanism of the biological effects. Moreover, there were few reports regarding the biological evaluation of the isolated compounds. As the development of new technique in isolation and biochemistry, close attention should be paid to biological evaluation and potential mechanism.

Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

Objective To develop an ideal cultural method to amplify embryonic hepatic stem cells and inhibit their differentiation in vitro. Methods Suspension of ED 14 Fischer (F) 344 rat em-bryonic hepatic stem cells was prepared by collagenase digestion and mechanical disaggregation. Then cells were divided into two groups randomly. The cells in group 1 were seeded into type I collagen-coated plates by adherent culture while those in group 2 were seeded into soft agar medium by suspen-sion culture. After culture for 2 weeks, the morphology and ultrastructure of cells in both groups were observed and compared by inverted microscope and transmission electron microscope, respectivley.The expression of CD90. 1 and CD49F, the two specific stem cell surface markers, was tested by flow cytometry to manifest the establishment of embryonic hepatic stem cells. Alkaline phosphatase stai-ning was used to detect stem cell differentiation. Result Embryonic hepatic stem cells in group 2 were characterized by higher nucleus-cytoplasm ratio and less cell organelles, higher expression of CD90. 1 and CD49F, and stronger positive reaction for alkaline phosphatase staining compared with those in group 1. Moreover, the cells in group 1 showed significant differentiation features. Conclusion Em-bryonic hepatic stem cells cultured suspendedly in soft agar medium experience less differentiation than those adherently cultured in serum-added culture medium, and can proliferate and form clone ball with a specific stem cell feature.

OBJECTIVETo investigate the efficacy of Chinese medicine Huangban Bianxing Recipe (HBR) for treatment of choroidal neovascularization (CNV).

METHODSEighty patients (97 eyes) suffered from CNV were assigned to two groups, the treated group treated by HBR orally taken one dose every day and the control group treated with ginkgo leaf tablet 1 tablet (19.2 mg) thrice a day, all for 3 months. The best corrected visual acuity (BCVA), fundus hemorrhagic area were measured; the neo-genetic vascular leakage area determined by fluorescent fundus angiography (FFA); and the out-layer high reflective band thickness (OHRBT) estimated by optical coherent tomography (OCT) were recorded before and after treatment.

RESULTSAfter treatment, in the treated group, BCVA was improved, with an effective rate of 67.12%, while in the control group, it was 33.33%, the former was better than the latter significantly (P < 0.05). The effective rate in reducing fundus hemorrhagic area in the two groups (85.11% vs 47.62%) and that in the CNV closure showed by FFA (67.50% vs 37.50%) were also superior in the treated group (P < 0.05). Besides, OCT showed that the OHRBT reduced significantly after treatment in the treated group (P < 0.01).

CONCLUSIONHBR can improve the vision, reduce the CNV leakage in the macular region, and advance the absorption of fundus hemorrhage in CNV patients.
