Diabetic nephropathy ( DN) is one of the complications of diabetes, which is closely related to the pathogenesis of in-flammation. This article summarized the relevant literatures on the correlation between MCP-1 , TNF-α and DN, and the intervention of traditional Chinese medicine with DN. In kidney tissues, oxidative stress and NF-κB-dependent signal pathways induced the increase of monocyte chemoattractant protein-1 (MCP-1) expression, which could induce macrophage accumulation, proteinuria increase, renal fibrosis and renal clearance capacity decrease, and further leading to kidney damage. The clinical and experimental trails showed tumor necrosis factorαmRNA and protein levels in serum, urine and renal tissues were closely related with DN, which could be used as a bio marker to provide clinical guidance. As the therapeutic targets,MCP-1 and TNF-αcould give a novel insight into the clinical treatment of DN. Some traditional Chinese medicines or monomer could ameliorate DN by inhibiting MCP-1 and/or TNF-α. Thus, further verifi-cation or clinical application of those traditional Chinese medicines is worth trying.

Objective To evaluate the effects of different concentrations of sevoflurane on the left ventricular function of patients.Methods Forty patients of both sexes,aged 30-50 yr,with body mass index of 18-25 kg/m2,of American Society of Anesthesiologists physical status Ⅰ,were divided into Ⅰ,Ⅱ,Ⅲ,and Ⅳ groups (n =10 each) using a random number table.The end-tidal concentration of sevoflurane was set at 2％,3％,4％ and 5％ in Ⅰ,Ⅱ,Ⅲ and V groups,respectively.The parameters of left ventricular function were monitored using the ultrasonic cardiogram.Before induction of anesthesia (T0,baseline) and at 3,5,8 and 10 min after the end-tidal concentration of sevoflurane reached the target concentration (T1-4),the left ventricular end-diastolic diameter,left ventricular end-systolic diameter,left ventricular ejection fraction (LVEF),left ventricular fractional shortening,cardiac output (CO) and heart rate (HR) were recorded.Results The LVEF,CO and HR were within the normal range.Compared with those at T0,the LVEF,left ventricular fractional shortening and CO were significantly decreased at T2-4 in Ⅱ-Ⅳ groups,the left ventricular end-systolic diameter was increased at T2-4 in Ⅲ and Ⅳ groups (P＜0.05),no significant change was found in the left ventricular end-diastolic diameter and HR at each time point in Ⅲ and Ⅳ groups,and no significant change was found in the parameters mentioned above in group Ⅰ (P＞0.05).Conclusion Inhaling 2％ sevoflurane produces no marked effect on the left ventricular function,3％-5％ sevoflurane exerts inhibitory effect on the left ventricular systolic function,and has no effect on the left ventricular diastolic function of patients.

Objectives To assess the value of external anal sphincter electromyography (EASEMG) in evaluating the related autonomic dysfunction in Parkinson's disease ( PD), parkinsonism dominant multiple system atrophy (MSA-P) and progressive supranuclear palsy (PSP). Methods From the records of EAS-EMG collected in our lab (total 562 cases), 60 PD (male 41, female 19), 68 MSA-P (male 35,female 33) and 13 PSP (male 10, female 3) were included in the analysis in this study. Mean duration,polyphasic ratio and satellite potential occurrence rate were comparable among the groups. Mean duration prolongation were graded as normal ( ＜ 10.0 ms), mild ( 10.0-11.9 ms), moderate ( 12.0-13.9 ms)and severe ( ≥ 14.0 ms). Results Among all related autonomic symptoms, the occurrence rate of constipation, urinary incontinence, urgency and frequency in patients with MSA-P(95.8% (23/24) ,94.6% (53/56) ,87.7% ( 50/57 ), 85.7% (42/49), 76.5% ( 39/51 ) ) were higher than that of PD ( 61.5%(16/26), 62.3% (33/53), 30.6% (15/49), 46.2% (24/52), 45.7% (21/46)) and PSP (75.0%(3/4) , 62.5% (5/8), 50.0% (4/8), 42.9% (3/7), 42.9% (3/7)). The abnormal rate of EAS-EMG in PD, MSA-P and PSP were 60.0%, 94.2% and 84.6%, accordingly. Mean duration ( PD ( 12.0 ± 1.6)ms, MSA-P (15.4±3.0) ms, PSP (13.8±1.8) ms), polyphasic ratio (PD 46.2% ±19.2%, MSA-P 63.9% ± 15.8%, PSP 51.5% ± 12.1% ) and satellite potential occurrence rate ( PD 9.5% ± 8.3%,MSA-P 26.5% ± 15.9%, PSP 19.2% ± 12.5% ) varied significantly different among the groups ( F =31.724, F = 17.412, x2 =45. 335, all P ＜0.01 ). Severe mean duration prolongation was overwhelming in MSA-P (66.2% ) , compared with mild 10.3% and moderate 23.5%. The predominant prolongation degree was moderate in PSP (61.5%, mild 7.7%, severe 30.8% ), and mild in PD (36.7%, moderate 36.7% ,severe 11.7%, normal 15.0% ). Conclusions EAS-EMG could play a role in evaluating the related autonomic dysfunctions in PD, MSA-P and PSP. The EAS-EMG impairment was severe and frequent in MSA-P, mild and infrequent in PD, moderate in PSP. The spectrum of mean duration prolongation suggested the possibility of Onuf's nucleus involvement in these diseases.
