1.Advance in Investigation of Transcranial Magnetic Stimulation (review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(10):879-882
Transcranial magnetic stimulation (TMS) is a non-invasive technique that can activate cortical motor areas and the corticospinal tract without causing the subject discomfort. Since TMS was introduced, numerous applications of this technique have been developed for the evaluation of neurologic diseases. They allow the evaluation of cortex excitability and motor conduction in the central nervous system and have been proved useful in monitoring motor abnormalities and the recovery of motor function. TMS also gives informations on the pathophysiology of the processes underlying the various clinical conditions and contribute to investigate the mechanisms of diseases. In addition, therapeutic use in depression, Parkinson's disease, epilepsy, spinal cord injury and stroke has raised great interest over the past decade. Theapplication of TMS has great potential both as an investigational and as a therapeutical tool in neurology and psychiatry. However, as an infant techniology, there should be further investigation and large randomized trials to be conducted.

Objective: To observe the changes of plasma levels of omentin-1 and vaspin in patients with acute coronary syndrome (ACS). Methods: Our research included in 2 groups: ACS group, the patients with conifrmed diagnosis in our hospital from 2013-05 to 2013-09,n=100 including 52 male, 48 female and Control group, the patients with simultaneous coronary angiography excluded CAD,n=88. Plasma levels of omentin-1 and vaspin were examined by ELISA and the differences were compared between 2 groups. Results: Plasma levels of omentin-1 and vaspin in ACS group were lower than Control group (t=2.718,P<0.05) and (t=2.416,P<0.05). Correlation analysis presented that in ACS group, omentin-1 level was negatively related to total cholesterol (TC) (r=-0.702,P<0.05) and C-reactive protein (CRP) (r=-0.714,P<0.05); vaspin was negatively related to TC (r=-0.655, P<0.05) and CRP (r=-0.587,P<0.05); Omentin-1 was positively related to vaspin (r=0.643,P<0.05). Multiple linear stepwise regression analysis showed that plasma levels of omentin-1 and vaspin might be affected by CRP, TC and LDL-C. Conclusion: ACS patients had decreased plasma levels of omentin-1 and vaspin; in addition, omentin-1 and vaspin might be involved in lipid metabolism.

Objective To evaluate the gender differences in neuromuscular blockade induced with rocuronium in patients undergoing abdominal surgery. Methods Twenty-four ASA Ⅰ or Ⅱ patients aged 20-59 yrs undergoing abdominal surgery under general anesthesia were enrolled in this study. Their body mass index (BMI) ranged between 18.5-25 kg?m-2. Patients with neuromuscular disease were excluded and no patient was taking any drug that might influence the effect of muscle relaxant. The patients were divided into male group ( n = 12) and female group (n = 12). The neuromuscular function was monitored and recorded using accelerography (DK-5210, Biometer, Denmark). The response of adductor pollicis muscle to train-of-four (TOF) stimulation of ulnar nerve were recorded. Body temperature was maintained at 36.0-36.9℃ and room temperature at 24-26℃ during surgery. The premedication included intramuscular atropine 0.01 mg?kg-1 and oral diazepam 10 mg. Anesthesia was induced with fentanyl 2-4 ?g?kg-1, propofol 2-3 mg?kg-1 and rocuronium 0.6 mg?kg-1. The patients were intubated and mechanically ventilated (VT = 7-10 ml RR = 12-14 bpm). PET CO2 was maintained between 35-45 mm Hg. Anesthesia was maintained with propofol by TCI (effect-site concentration was set at 3-4 ?g?ml-1) and intermittent i.v. boluses of fentanyl. Rocuronium (1 mg?ml-1) was infused and T1 was maintained at 5%-10% of the control height. At the end of surgery rocuronium infusion was terminated and neostigmine 0.05 mg?kg-1 was given i.v. .Results There were significant differences in body weight and height between male and female groups ( P

Objective Base on the theory of traditional Chinese medicine (TCM), obtained human diagnostic information available for joint syndrome differentiation is integrated based on subjective and objective combined syndrome differentiation, in the form of data expression of TCM four diagnosis, forms multiple information fusion of open platform for TCM diagnosis and treatment, and provides some revelation for promoting the development of depression and treatment technology. Methods Totally 30 depression patients and 30 normal people were selected according to the inclusion criteria. TCM four diagnostic and auxiliary diagnosis instrument was used to collect information of four diagnosis, and the statistical software was used for the analysis on pulse diagnosis, and information features of digitalized tongue and listening diagnosis of patients in depression group and normal group were studied. Results Compared with depression group, pulse frequency, fluency, and heart rate of normal group were a bit higher than depression group, without statistical significance (P>0.05);There was statistical significance among pulse frequency, strength, tightness, and pulse wave velocity between the normal group and depression group (P<0.05). 30 patients had 6 depression syndrome types:heart-gallbladder qi deficiency (8 cases), phlegm-heat attacking internally (6 cases), fire excess from yin deficiency (6 cases), liver depression forming fire (6 cases), intense heart fire (3 cases), and heart-spleen deficiency (3 cases). Conclusion The results of differences in pulse diagram parameters were consistent with the theory of classical TCM pulse theory. The results of differences in pulse wave velocity conform to the modern medical research conclusion. TCM four diagnostic auxiliary diagnosis and treatment technology can realize the dynamic detection of depression patients with four diagnostic information, and establish diagnostic methods for depression based on digitalized four diagnostic auxiliary diagnosis.
