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.

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.

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.
6. Research progress in Litsea glutinosa
Chinese Traditional and Herbal Drugs 2017;48(2):400-405
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.

AIM: To explore the long-term efficacy of Q-factor guided laser epithelial keratomleusis ( LASEK ) for myopia and astigmatism with positive Q-factor.
METHODS: There were 158 eyes which were myopia and astigmatism with positive Q- factor taken in two groups randomly: 86 eyes accepted Q - factor guided LASEK as observation group and 72 eyes accepted routine LASEK as control group. The difference between the two groups about all data was similar. The uncorrected visual acuity ( UCVA ) and the best corrected visual acuity ( BCVA ) as well as diopter, ocular tension, corneal topography, Keratometry value K, aspherical factor Q, Higher-order aberrations ( HOA ) , corneal thickness by ultrasound and, contrast sensitivity ( CS ) , Haze were examined and compared before and after surgery. All the cased were followed up for 14d, 1, 3, 6, 12mo. And there were no statistical difference among the data before surgery.
RESULTS: After 12mo there were no statistical difference between the two groups about UCVA and BCVA. But the safety index of observation group was 1.10, that of control group was 1. 07. The validity index of observation group was 1. 06, that of control group was 0.99. The HOA of observation group was 0. 45±0. 17μm, and that of control group was 0. 72±0.25μm, there was statistically significant difference (t=-8. 193,P=0. 000). Q factor of observation group was 0. 41±0. 17, that of control group was 0. 77±0. 22, there was significant difference (t=11. 377,P = 0. 028). The contrast sensitivity of 3mo post surgery of patients in the observation group returned to the level of before surgery. But in the control group the contrast sensitivity of the patients did not returned until 6mo.
CONCLUSION:Q-factor guided LASEK for myopia and astigmatism with positive Q-factor is stable, safe and effective. The operation allow for reducing the high order aberrations, maintaining the most asphericity of cornea, saving more in corneal tissue, which cause faster recovery of contrast sensitivity, less haze and better visual quality.
10.On relationship of acupoint-injection with injury of peripheral nerves.
Chinese Acupuncture & Moxibustion 2007;27(4):294-296
OBJECTIVETo provide basis for strengthening safety of acupoint-injection and increasing clinical therapeutic effect.
METHODSAnalyze and study on the relative articles from the databank of whole articles of Chinese periodicals of CNKI by information retrieval with computer, with acupoint-injection, nerve injury as key words.
RESULTSMost of clinical reports focus on acupoint-injection for treatment of nervous injury induced by trauma and birth injury. The studies indicate that the injuries of the peripheral nerves induced by acupoint-injection can be divided into 3 grades and the injury mechanisms can be divided into 3 classifications. The injuring causes include improper posture of the patients, improper angle and depth of injection and improper medicine selection.
CONCLUSIONAcupoint-injection can be applied more widely as soon as the accomplishment of the standardization of operation.
