Objective To study the effects of repetitive transcranial magnetic stimulation(rTMS) of the supplementary motor area(SMA)on the cortical excitability in patients with Parkinson's disease(PD).Methods Sixteen patients with PD were included in this study.The motor evoked potentials(MEP)and the N30 component of somatosensory evoked potentials(SEP) were assessed for each patient before and after 1200 pulses of rTMS of the SMA at 5 Hz and an intensity of 100% of relaxed motor threshold (RMT) for the abductor pollicis brevis.Results Ten minutes after the rTMS intervention,the peak-to-peak amplitude of the SEP component P20-N30 increased significantly(P<0.05),with the P/F index decreased simultaneously(P<0.05).The MEP amplitude increased significantly,and reached the highest value at 10min after the rTMS intervention. Conclusion 5 Hz rTMS of the SMA can improve the excitability of the SMA itself temporarily.Meanwhile,it can induce a short-lasting facilitation of the excitability of M1 connected with SMA.

The body surface area of adult Chinese males was estimated by using paper cast method.56 healthy individuals, aged 18 to 45, coming from thirteen provinces mostly from Hebei and Hubei were used in this study. From the results obtained, the mean body weight, height and surface area were 59.78kg, 168.8 cm and 1.712 m2 respectively. A height-weight equation for estimating body surface area was derived accordingly, i.e. body surface area(m2)= 0.00607H(cm) + 0.0127W(kg)-0.0689. The error of the value calculated from the equation was 0.17% higher than the value actually taken on an average. The percentage of various body regions to the total body surface area was as follows: head, 6.11; trunk (including neck), 29.59; upper arms, 8.09; forearms, 6.41; hands, 4.93; thighs (including buttock), 24.63; calf, 13.29 and feet, 6.95.For convenient use a table for calculation was given.

ObjectiveTo analyze the risk factors of pulmonary infection for critically ill ICU patients with tracheotomy,and investigate the methods to prevent nosocomial lung infection. Methods94 patients in ICU with pulmonary infection after tracheotomy from March 2008 to March 2010 were analyzed retrospectively,they were set as the observation group.100 patients in synchronization without pulmonary infection after tracheotomy were set as the control group.The general condition,diagnosis and treatment methods and care,the environment,etc.were studied,the risk factors for nosocomial pulmonary infections after tracheotomy were analyzed.The care methods and points to prevent lung infections for critically ill ICU patients after tracheotomy were summarized. ResultsThe study showed that the respiratory system diseases in critically ill patients,smoking history,low seniority of nursing staff,long-term use of large dose of antibiotics,application of H2 blockers and antacids,and many patients in the same ward were risk factors for critically ill patients with pulmonary infection. ConclusionsLung infection after tracheotomy in critically ill ICU patients was affected by many factors.In the actual operation,we should targeted to avoid infection led by treatment and care factors,environmental factors,control and prevention measures should especially be strengthened for patients with respiratory diseases to prevent lung infection.

Immunohistocheraistry and RT-PCR were used to examine the expression of toll-like receptor 4 (TLR4) in the kidney of diabetic rats.Compared with normal control group,the expression of TLR4 in diabetes mellitus group was increased ( P ＜ 0.05 ).Compared with diabetes mellitus group,the expression of TLR4 in simvastatin treated group was decreased( P＜0.05 ).The results suggest that TLR4 may play a role in the pathogenesis of diabetic nephropathy.Simvastatin seems to delay the progress of diabetic nephropathy via reducing TLR4 expression.

We had previously reported the height-weight formula for the estimation of body surface area of adult Chinese males (this journal 6(2):87, 1984). In this study, by using the same paper cast method, a formula for the adult Chinese females was obtained from the data of 44 healthy subjects (age 18-45) coming from 15 provinces. The mean body weight, height and surface area measured were 52.13?6.22 kg, 159.3?5.18 cm and 1.546?0.105 m2 respectively. The formula thus derived was: body surface area (m2) = 0.00586H (cm) +0.0126W (kg)-0.0461. The value calculated from it was 0.03% less than the value actually measured on an average. The percentage of various body regions to the total body surface area was as follows: head, 6.33; trunk (including neck), 28.27; upper arms, 8.29; forearms, 6.65; hands, 4.52; thighs (including buttocks), 27.40; calves, 12.83 and feet, 6.65.

Objective To pick up the Chinese materia medica with principal antidepressive effect in Kaixin Jieyu prescription based on uniform distribution. Methods 11 groups of concerted application with different dosages of six simplex Chinese materia medica (X 1-X 6) of Kaixin Jieyu prescription were arranged by the designlist and sustentacular table of U11(1110). Positive and negative control groups were also formed. Mice were randomized into 13 groups according to body weight and fed with medicine 14 d and estimated by tail suspension test, forced swim test and autonomic activities test. Results Relationship of percentage of immovability time (Y 1) in the tail suspension test and X 1-X 6 were analyzed with multivariant non-linear regression analysis and resulted in Y 1=1.133 1-0.842 3×X 1+0.438 2×X 3-0.712 9×X 6. It indicated that both Radix Ginseng and Fructus Aurantii Immaturus had obvious antidepressive function, and Radix Paeoniae Rubra may facilitate depression. Relationship of immovability time (Y 2) in forced swim test and X1-X6 were analyzed with multivariant non-linear regression analysis and resulted in Y 2=167.69-2.99×X 12-2.14×X 1-1.65×X 6. It also indicated that both Radix Ginseng and Fructus Aurantii Immaturus had obvious antidepressive function. Relationship of autonomic activities index (Y 3) in autonomic activities test indicated that X 1-X 6 had no obvious influence on Y 3 and antidepressive function of KaixinJieyu prescription was not concerned with excitability to the central nervous system. Conclusion Radix Ginseng and Fructus Aurantii Immaturus were the Chinese materia medica with principal antidepressive effect in Kaixin Jieyu prescription.
