Objective To observe the effects of electroacupuncture at Zusanli (ST36) on lower limbs motor function in patients with stroke. Methods 63 patients were evenly randomized into electroacupuncture group and control group. All the patients received routine rehabilitation training and at the same time,patients in electroacupuncture group, received electroacupuncture at zusanli (ST36). They were assessed with Fugl-Meyer Assessment (lower limb, hip, knee and ankle), gait analysis (gait frequency, gait speed and step length of both sides) and lower limb Composite Spasm Scale (CSS) before and after treatment. Results The scores of Fugl-Meyer Measure, gait analysis, and CSS improved in both groups, and more significantly in electroacupuncture group. Conclusion Electroacupuncture at zusanli (ST36) can significantly improved lower limb motor function without worsening the spasm.

Objective To explore the effect of acupuncture on stroke patients in hemiplagic spasm period.Methods63 stroke patients in hemiplagic spasm period were randomly divided into the electro-acupuncture group(n=31) and control group(n=32).All patients of two groups received routine rehabilitation training,but those of the electro-acupuncture group were added with electro-acupuncture at "Zusanli"(ST36).The composite spasticity scale(CSS) score,H/Mmax and muscular compliance of two groups before and after treatment were observed and compared.ResultsThe CSS scores and H/Mmax and grading gastrocnemius muscular compliance of the electro-acupuncture group were superior to that of the control group(P<0.05～0.01).ConclusionAcupuncture can decrease muscular tension and increase motor function of stroke patients in hemiplagic spasm period.

Objective To investigate the effects of trichostatin A (TSA) on cell proliferation and cell cycle in human gastric cancer cell line SGC-7901 in vitro and its mechanism. Methods SGC-7901 cells were treated with 0.1, 0.5 and 2.0 μmol/L of TSA for 24 hrs. Growth inhibition rates of cells were measured by MTT assay and cell cycles were detected by flow cytometery (FCM). Expressions of cyclin D1 and p21 mRNA were measured by real-time PCR. Results The proliferations of SGC-7901 cells were inhibited when treated with TSA for 24 hrs. The inhibition rates in groups treat with 0.1, 0.5 or 2.0 μmol/L of TSA were 3.52%±6.11%, 13.29%±4.13% or 14.24%±2.80% ,respectively. The cell percentage of G0/G1 phase were higher in 0. 5 pznol/L group (71.26%±0.51%) and 2.0 μmol/L group (71.03%±0.12%) compared with control group (51.12%±1.17%). The cell percentage of S phase were lower in 0.5 μmol/L group (13.55%±0.44%) and 2.0 μmol/L group (10.63%±0.63%) compared with control group (34.60%±0.60%). The expression of cyclin D1 mRNA was down-regulated, whereas p21 mRNA expression was up-regulated. Conclusions TSA inhibits SCG-7901 gastric cancer cell proliferation by affecting the cell cycle control gene eyclin D1 and p21 mRNA expressions, which induce G0/G1 cell phase cycle arrest and ultimately impact on the growth of tumor cells.

The purpose of education is to cultivate talents who can master the ability of self-learning lifelong. With the rapid development of multimedia technology, the knowledge carrier represented by micro curriculum plays a very important role in improving students' self-learning ability. In traditional Chinese medicine college, due to the short of time, weak learning foundation, the ability of self-learning is hard to improve in the modern medical courses such as biochemistry. This is not conducive to the cultivation of modern talents of Chinese medicine. In this paper, we chose the biochemistry teaching in TCM college as an example, and discuss how we can make the application of micro courses reasonably in the teaching process. This study was regarded as a starting to improve the students' self-learning ability effectively.

Objective To explore the effect of low frequency repetitive transranial magnetic stimulation (rTMS) on unilateral spatial neglect (USN). Methods 40 stroke patients with USN were divided into treatment group (n=20) and control group (n=20). Patients in the treatment group were treated with low frequency rTMS for 2 weeks. The USN degree of these groups were evaluated before and after the treatment. Results There was no significant difference of USN degree between these groups before the treatment (P>0.05); Compared with the control group, the treatment group improved significantly after the treatment (P<0.05). The USN degree of patients in the treatment group decreased significantly after the treatment (P<0.05), while patients in the controlled group had no difference (P>0.05). Conclusion USN induced by stroke could be improved obviously through low frequency rTMS.

Objective To investigate the effect of trichostatin A (TSA) on inhibition of cell proliferation and cell cycle of human pancreatic cancer cell line PaTu-8988 in vitro. Methods PaTu-8988 cells were treated with different concentration TSA (0.1,0.5,2.0μmol/L), and blank control group was used. The growth inhibition rates of cells were measured by WST-8 method. Cell cycle and apoptosis were detected by flow cytometry; the expressions of p21 mRNA and HDAC1 mRNA were measured by Real-Time PCR. Results Survival rates of TSA 0.1μmol/L,0.5μmol/Land2.0μmol/L group was (88.5±4.2)%, (79.7±5.O)% and (64.3±7.2)%, respectively, which were all significantly lower than (100.0±4.2)% of the blank control group (P<0.01). Cells in the group of TSA O.1μmol/L and 0.5μmol/L were hindered at G1 phase, while (50.29±7.53)% of the cells in the group of TSA 2.0μmol/L were hindered at G2/M phase. The expression rates of p21 mRNA in different TSA group were 5.29±1.16, 7.79±0.41, 8.61± 0.73, respectively, which were higher than that in the control group (1.00±0.08, P<0.01); the expression rates of Cyclin DI mRNA were 1.13±0.12, 0.42±0.06, 0.19±0.06, respectively, which were higher than that in the control group (1.00±0.07, P<0.05). Conclusions TSA may up-regulate the expression of p21 and down-regulate the expression of cyclin D1, and induce cell cycle blockade.

Objective To investigate the expressions of DNA methyltransferase 1 (DNMT1) in pancreatic carcinoma and its clinical significance.Methods 30 samples of pancreatic cancer tissues and paired para-cancerous tissues were collected from patients who underwent curative pancreatectomy.The levels of DNMT1 mRNA were detected by real-time RT-PCR.Expressions of DNMT1 protein were detected by streptavidin peroxidase immunohistochemistry.The relationships between expression of DNMT1 and clinicopathological findings were analyzed.Results The value of relative quantification (RQ) of DNMT1 mRNA in human pancreatic cancer tissues was 2.32 (1.17 ～ 5.17 ), which was significant higher than 0.78 (0.07 ～3.14) in para-cancerous tissues(P ＜0.05).The index of expression of DNMT1 protein in human pancreatic cancer tissues was (54.5 ±21.2)% ,which was significant higher than( 10.9 ± 15.0)% in paracancerous tissues (P ＜ 0.01 ).Patients were divided into the high DNMT1 group (n = 19) with above 54.5% of the DNMT1 positively cancer cells and the low DNMT1 group ( n = 11 ) with less than 54.5% of the DNMT1 positively cancer cells.The high expression of DNMT1 was correlated significantly with clinical staging ( x2 =6.897, P = 0.029), lymph node metastasis ( x2 = 4.739, P = 0.029) and neural invasion ( x2 = 5.44, P =0.020).On the other hand, no association between DNMT1 expression and age, gender, tumor location,tumor size, tumor differentiation, the serum CEA and CA19-9 levels could be found.Conclusions DNMT1 mRNA and protein was highly expressed in pancreatic cancer tissues.High expression of DNMT1 might be related to the aggressiveness of pancreatic cancer, lymph node metastasis and neural invasion.

Objective To investigate the clinic significance of HDAC1 expression in human pancreatic carcinoma.Methods 30 samples of pancreatic carcer tissues and paracancerous tissues were collected.HDAC1 expression was detected by real-time PCR and immunohistochemistry techniques.The relationships between clinicopathological findings and the expression of HDAC1 were analyzed. Results The RQ level of HDAC1 mRNA expression in human pancreatic carcinoma tissues and paracancerous tissues was 2.60(0.42～12.81)and 1.02(0.19～3.58),respectively(P=0.001).The percentage of positive cells expressed HDAC1 protein in human pancreatic carcinoma tissues and paracancerous tissues were(56 ±26)%and(6±6)%,respectively(P=0.000).The highly expressed HDAC1 correlated significantly with an advanced TNM stage and lymph node metastasis.Conclusions In pancreatic carcinoma tissues,highly expressed HDAC1may indicate the status of advanced TNM stage and poor prognosis.
