Objective To observe the effect of rhythmic auditory stimulation (RAS) on gait of stroke hemiplegic patients. Methods From April, 2014 to April, 2015, eleven stroke hemiplegic patients were divided into RAS group (n=6) and control group (n=5) randomly. Both groups accepted routine rehabilitation, and the RAS group accepted RAS walking exercise, while the control group accepted verbal in-structed walking exercise. They were tested with Brunnstrom's Stage and gait analysis before and three weeks after training. Results There was no significant increase in Brunnstrom's Stage (Z<1.414, P>0.05) in both groups after training. The RAS group increased in stride length, velocity and cadence (t>4.829, P<0.01) after training, and improved in temporal symmetry (t=3.323, P<0.05), while there was no significant change in all of the indices in the control group (t<1.765, P>0.05). Conclusion Walking exercise under RAS facilitates to improve gait in stroke hemiplegic patients.

The neuromechanism of language function recovery in patients with aphasia after stroke is still unclear. It is supported that the language function of aphasia after extensive damage of left hemisphere mainly recovered through activating the right hemisphere of ho-mologous regions to improve the function of speech. Melodic intonation therapy (MIT) can be achieved by melody tone and left hand clap to activate the right hemisphere of the frontal temporal lobe, which is particularly applicable to improve language function of non-fluent aphasia patients with large left hemisphere lesion. Non-invasive brain stimulation techniques (NBS) changes brain activity through stimulat-ing affected or contralateral side, which has been used to facilitate language functional recovery after stroke. Excitatory transcranial stimula-tion on the right hemisphere homology combined with melodic intonation therapy can promote language recovery of patients with extensive damage of left hemisphere after stroke. It is valuable to combine traditional speech training with MIT and NBS to activate related language functional areas to maximum improvement of language recovery after stroke.

Objective　To investigate the involvement of cell cycle negative regulator p16 in the replicative senescence of normal human diploid fibroblasts. 　Methods　 p16 cDNA and retroviral vector was introduced into normal human fibroblast 2BS cells by transfection technique. Then the effects of p16 on replicative cellular senescence of 2BS cells were examined. 　Results　 Compared with the control cells, 2BS cells transfected with p16 cDNA showed significant suppression of growth rate (decrease 50%) with cell cycle arrested at G1 phase. This phenomenon similar to that of the senescent cells, with the cellular response to stimulation by growth factor decreased 79.4%, showing the characteristics in morphology of senescent fibroblasts. 　Conclusions　 The over expression of p16 gene contributes to the process of cellular senescence of normal human diploid fibroblasts.

BACKGROUND: Lanceolata and astragalus can improve myocardial ischemia, which are widely used in clinics.OBJECTIVE: To compare the effects of extract of lanceolata and astragalus on electrocardiogram (ECG) of rats with experimental myocardial ischernia.DESIGN: Completely randomized and controlled study.SETTING: Pharmacological College of Harbin Commerce University.MATERIALS: The experiment was carried out at the Laboratory of Pharmacological College of Harbin Commerce University from September to December 2002. Totally 30 healthy adult Wistar rats were divided randomly into 3 groups: control group, lanceolata group and astragalus group with 10 in each group.METHODS: ① After anesthesia, lead ECG Ⅱ of rats was recorded.30 g/kg saline, 30 g/kg lanceolata extract and 30 g/kg astragalus extract [extract of lanceolata and astragalus (raw drug: 1 g/mL)] were injected into rats in the control group, lanceolata group and astragalus group respectively. After 1-3 minutes, 0.5 U/kg pituitrin was injected intravenously (for model of myocardial ischemia), and then saline was used to dilute from 0.1to 0.2 mL for 10-second injection. Changes of ECG after injection of pituitrin were recorded with LMA-2B Ⅱ physiological recorder (migration of T wave and ST section and change of heart rate). ② Differences of data were compared with t test.MAIN OUTCOME MEASURES: Height of T wave and Migrations of ST section and changes of heart rate of ECG of rats before and after medication.RESULTS: Data of totally 30 rats was entered the final analysis. ①Height of T wave: The height was higher after medication than that before medication in three groups (P ＜ 0.01), but that in astragalus group was obviously lower than that in lanceolata group [(1.63±3.81), (2.18±2.93) mm,P ＜ 0.01]. ② Heart rate: The rate was lower after medication than that of before medication in three groups (P ＜ 0.01), and that in astragalus group was obviously lower than that in lanceolata group [(212.21 ±5.01),(221.18±5.66) time/minute, P ＜ 0.01]. ③ Height of ST section: There were not significantly different in three groups (P ＞ 0.05), and the difference was not obvious before and after medication (P ＞ 0.05).CONCLUSION: ① Both astragalus and lanceolata can protect experimental myocardial ischemia induced by pituitrin. ② Effect of lanceolata on reduction of T-wave height is stronger than that of astragalus, but the effect of lanceolata on reduction of heart rate is weaker than that of astragalus.

Objective To investigate the clinical manifestations, endoscopic manifestations, histological characteristics, diagnosis and treatment of the primary gastrointestinal melanoma in China. Methods The gender, age, position, endoscopic manifestations, histological characteristics, treatment, prognosis of the primary gastrointestinal melanoma were gathered and analyzed by reviewing retrospectively the data of 2 cases seen at our hospital and 449 cases searched in CNKI from 1983 to 2015. Results The primary gastrointestinal melanoma was mostly seen in the rectum and anus, and secondly in the esophagus. A typical endoscopic finding was a protuberant or nodular tumor, with erosion or dirty surface on it. Most lesions were friable and easily hemorrhagic. The maximum diameters of most lesions, accounted for 83.3 %, were larger than 2.0 cm. The average value of the maximum diameters was (4.79 ± 2.67) cm. Most cases presented brown or black, followed by hoar. However, some lesions presented various colors, such as blue, red, even co-exited color or achromatic color. Preoperative misdiagnosed rate was 73.64 % and 1-year mortality was 54.19 %. Negative correlation was observed between survival time and lesion size, infiltration depth. Positive correlation was observed between lesion size and metastasis infiltration depth. Survival time had nothing to do with metastasis and age. Conclusion The primary gastrointestinal melanoma was highly aggressive, and usually found in the terminal age, usually together with extensive metastasis, misdiagnosed and poor prognosis. Knowing the clinical features, endoscopic manifestations, histological and immunohistochemical characteristics is the key to early diagnosis.
