OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

AIM:To investigate the efficiency of 2-methoxyestradiol (2-ME) as radiosensitizing agent for the treatment of lung cancer cells. METHODS:Cell line A549 and GLC-82 originated from human non-small cell lung cancer were cultured in vitro. Study group (2-ME in different concentrations) and control group without 2-ME were set up. Cell proliferation was measured by MTT assay that lung cancer cells were treated with 2-ME for 24 h,then the cells were exposed from 0 to 8Gy radiation,and the survival fraction was determined by clone forming test. Flow cytometry was used to measure the effects of 2-ME on cell cycle distribution. RESULTS:MTT assay showed minimum effective concentration value was 0.15625×10~(-6) mol/L in GLC-82 and 1.25×10~(-6) mol/L in A549 cells. Compared to control group,exposed GLC-82 cells or A549 cells to minimum effective concentration of 2-ME for 24 h before irradiation resulted in an enhancement of radiation. The protection enhancement factor was 1.98 and 2.06 in GLC-82 and A549 cells,respectively. Flow cytometry analysis of cell cycle progression demonstrated G_2/M phase arrest in both cells in a dose dependent manner. No obvious change of CDK2 activity in both GLC-82 cells and A549 cells was observed. CONCLUSION:2-ME enhances radiosensitivity by G_2/M phase arrest in the cell cycle.

AIM AND METHODSWhole-cell recording technique was used to observe the changes of voltage-dependent ion channels and NMDA receptor currents of rat hippocampal neurons during primary culture.

RESULTSThere was no significant difference of voltage-dependent Na+ current (I(Na)) at 7 d, 14 d and 21 d in culture. It's the same for delayed rectifier K+ current (Ik). However, voltage-dependent Ca2+ current (I(Ca)) and its density were continuously and markedly increased. Further studies showed that the increase of I(Ca) was resulted from the increase of L-type voltage-dependent Ca2+ channels (L-VDCC). NMDA receptor current was also significantly increased with time of culture.

CONCLUSIONCa2+ influx through VDCC and NMIDA receptor is the fatal factor in the aging and death of hippocampal neurons.

Objective To study the risk factors of hyperthyroid heart diseases(HHD) by analyzing clinical features of patients in order to provide a scientific basis for prevention and treatment of HHD. Methods Nine hundred and eighty two cases were selected as objective from in-patient data of Thyroid Disease Treatment Centre of Shandong Province. The cases were divided into hyperthyroidism group and HHD group. The variables of etiology,sex, age, duration of disease, TSH, FT3, FT4 and TRAb were analyzed by comparative analysis. The risk factors were analyzed by logistic regression. Results The prevalence of hyperthyroidism complicated hyperthyroid heart disease was 7.7%(76/982), age, duration of diseases, FT3, TRAb in the HHD group were [(51.4 ± 11.5), (6.3 ±2.1) years, 21.6 pmol/L, 71.6 U/L], in hyperthyroidism group were [(37.9 ± 9.8), (2.6 ± 1.3) years, 14.9pmol/L, 49.6 U/L]. The differences were statistically significant(u = 9.93,15.23, T = 44954,48792.5, P ＜ 0.05)between the two groups. The factors of the older, higher FT3 and TRAb, longer duration, Graves disease (OR =1.751,1.470,1.483,1.445,1.234) increased the risk of HHD. Conclusions Graves disease, longer duration, old age, higher FT3 and TRAb are the risk factors of HHD. Timely prevention and control of risk factors is necessary to reduce the incidence of HHD.

Objective To explore whether the expression level of heparanase (HPA) and its coagulation proteins on leukemic blast membrane could determine the hemostatic balance on the surface of leukemia cells.Methods Forty patients of leukemia were studied,and 20 patients with iron dificient anemia as the control group.Expression of tissue factor (TF),heparanase (HPA),tissue factor pathway inhibitor (TFPI),and urokinase plasminogen activator receptor (UPAR) on leukemic blast surfaces were analyzed by flowcytometry.Results The expression of TF,UPAR,and HPA in AML,ALL,CML,CLL and CRAL groups were significantly higher compared with the control group (t =.3.289,3.507,2.701,P ＜0.05; t =2.498,0.802,3.090,P ＜0.05; t =2.642,3.308,2.696,P ＜0.05; t =3.417,3.434,2.382,P ＜0.05; t =2.193,2.272,2.263,P ＜0.05).There were no significantly differences between the leukemic cell expression of TFPI and the control group (P ＞0.05).Expression of TF,UPAR,HPA in AML patients were significantly higher than ALL,CML and CLL groups (t =2.463,2.179,2.276,P ＜0.05; t =2.637,2.402,2.095,P ＜0.05; t =2.548,2.425,2.412,P ＜0.05).The levels of TF,UPAR and HPA in M3,M4 and M5 patients were higher than that of M1,M2 groups (P ＜0.05).There were no significantly differences among M3,M4 and M5 (P ＞0.05).Conclusions These results suggest that TF,UPAR and HPA are predominately expressed on leukemic blast surface,particularly in M3and M4,5 subtypes.The expression of coagulation proteins on blast membrane might determine the hemostatic balance on the surface of leukemia cells.
