Objective To study the efficacy and safety of treating Parkinson disease(PD) by repetitive transcranial magnetic stimulation (rTMS). Methods 45 patients with PD were randomly divided into two groups. 30 patients received rTMS therapy and 15 patients were given sham stimulation. Stimuli were delivered at an intensity of 110% of resting threshold (RT) and a frequency of 1Hz once a day for 10 days. All the patients were followed-up at 1 month and 3 months after treatment. The efficacy was assessed by UPDRS score, grooved pegboard test, timed motor test and 10m turned back test. All the patients stopped using dopaminergic drugs for at least 12h before each assessment. Results In rTMS treatment group, the UPDRS total scores, UPDRSⅠ-Ⅲ, the mean times of grooved pegboard and 10m turned back test were significantly decreased 10 days after treatment compared with pre-treatment (all (P)0.05), and PDQ scores significantly decreased 3 months after treatment. In sham treatment group, there was no difference of each index between pre- and post-sham treatment.Conclusion Low frequency rTMS may improve the symptoms of the patients with PD and raise their quality of life.

Objective To study the effect of hypothyroidism on oxidative stress status in developing rat brain and to further explore the mechanism of impaired brain development caused by hypothyroidism. Methods Perinatal hypothyroidism was induced by administering propylthiouracil(PTU) solution to the dams by gavage.The oxidative stress indexes were measured in brain homogenate of normal and hypothyroid pups which were sacrificed on the 21st d after birth. Results As compared to the control,the following indexes were found to be increased in the hypothyroid group: protein carbonyl contents,thiobarbital acid reactive substances,reduced glutathione,total antioxidative capacity,activities of superoxide dismutase and glutathione peroxidase(P0.05). Conclusion Hypothyroidism during rat brain development may cause oxidative stress,which may be related to the brain damage caused by hypothyroidism.

Objective To evaluate the effect of infiltration anesthesia at Calot's triangle on postoperative analgesia in the patients undergoing laparoscopic cholecystectomy.Methods One hundred and forty patients,aged 18-64 yr,with 18 kg/m2 ≤ body mass index ≤ 31 kg/m2,of ASA physical status Ⅰ or Ⅱ,scheduled for elective laparoscopic cholecystectomy,were randomly divided into 2 groups (n =70 each):control group (group A) and infiltration anesthesia at Calot's triangle group (group B).In group B,1％ ropivacaine 10 ml was injected into Calot's triangle before dissection of the gallbladder,while the equal volume of normal saline was injected into Calot's triangle in group A.The patients in both groups received patient-controlled intravenous analgesia (PCIA) for 48 h starting from 10 min before the end of surgery.The VAS score was maintained below 4 during PCIA.When VAS score ≥ 4,lasting for more than 30 min,tramadol 1.5 mg/kg was injected intravenously.The consumption of physic liquor for PCIA,and requirement for tramadol were recorded.The incidence of puncture-related damage to Calot's triangle and local anesthetic intoxication and adverse effects such as nausea and vomiting within 48 h after surgery were also recorded.The first postoperative flatus time was recorded.Results Compared with group A,the consumption of physic liquor for PCIA,requirement for tramadol,and consumption of tramadol were significantly reduced,and no significant change was found in the incidence of nausea and vomiting and the first postoperative flatus time in group B.No puncture-related damage to Calot's triangle occurred in A and B groups.There was no local anesthetic intoxication in group B.Conclusion Infiltration anesthesia at Calot's triangle can optimize postoperative analgesia in the patients undergoing laparoscopic cholecystectomy.

Objective To investigate the protective effect of pretreatment with Shenfu injectio(SFI)on myocardium against ischemia-reperfusion(I/R)injury in diabetic rabbits.Methods Forty healthy adult male rabbits weighing 2.4-3.2 kg were used in this study.Type I diabetes mellitus was induced by intravenous alloxan 120 mg?kg~(-1) and confirmed by fasting blood glucose＞11.1 mmol?L~(-1).The animals were randomly divided into 5 groups(n=8 each):groupⅠsham operation;groupⅡI/R and groupⅢ,Ⅳ,ⅤSFI+I/R.I/R was produced by occlusion of the anterior descending branch of left coronary artery(LAD)for 60 min.The occlusion of LAD was then released for reperfusion.In sham operation group(Ⅰ)LAD was exposed but not occluded.In groupⅢ,ⅣandⅤSFI 5,10 and 15 ml?kg~(-1) was givenⅣrespectively 30 min before myocardial ischemia.MAP,HR,left ventricular developed pressure(LVDP),?dp/dt_(max),left ventricular end-diastolic pressure(LVEDP)and Vmax were recorded immediately before ischemia(T_0,baseline),at 5 min of ischemia(T_1),immediately before reperfusion(T_2)and at 5,15,60,90,120 min of reperfusion(T_(3-7)).The animals were killed and hearts removed for determination of infarct size and microscopic examination of the ultrastructure of LAD using transmission electron microscope.Results MAP,HR,LVDP,?dp/dt_(max) and Vmax were significantly decreased while LVEDP was significantly increased during reperfusion as compared to the baseline values at T_0 in I/R group. I/R produced myocardial infarct and damage to the endothelial cells of LAD.The harmful effect of I/R was attenuated by different doses of SFI.SFI 10 ml?kg~(-1) provided best effect.Conclusion Pretreatment with SFI can protect the myocardium against I/R injury in diabetic rabbits.SFI 10 ml?kg~(-1) produces better effect.
