ObjectiveTo investigate the effect of acupuncture on motor function and serum expressions of TNF-aand IL-6 contents in cerebral hemorrhage rats.MethodSeventy-two male Wistar rats were randomized into sham operation, model and acupuncture groups. A rat model of cerebral hemorrhage was made by intracerebral injection of autoblood. Baihui-to-Qubin acupuncture was performed after successful model making. The TNF-aand IL-6 contents of rat serum were measured by enzyme linked immunosorbent assay at three time points: one, three and seven days.ResultBaihui-to-Qubin acupuncture markedly increased the neurological function score and reduced neurologic deficits in cerebral hemorrhage rats. At the same time point, serum TNF-aand IL-6 contents were significantly lower in the acupuncture group of rats thanin the model and acupuncture group; there were statistically significant differences (P<0.01).ConclusionBaihui-to-Qubin acupuncture can reduce neurologic deficits in cerebral hemorrhage rats. It may be related to decreases in serum TNF-aand IL-6 contents after acupuncture.

Background One of the features of the pathogenesis of primary angle-closure glaucoma(PACG) is anterior synechia of peripheral iris.Goniosynechialysis and combination of phacoemulsification and goniosynechialysis have been applied for the treatment of the disease recently,but the selection of operative types has great impact on clinical efficacy.Objective This study was to investigate the long-term efficacy of goniosynechialysis and combination of phacoemulsification and goniosynechialysis for the management of chronic PACG.Methods A non-randomized clinical controlled trial was designed.This clinical trial complied with Declaration of Helsinki and was approved by Medical Ethic Committee of Nanjing Medical University.Written informed consent was obtained from each patient.One hundred and ten eyes of 110 patients with chronic PACG were assigned to the goniosynechialysis group and combined operative group from March,2008 to February,2011 in Wuxi People's Hospital.180° goniosynechialysis was performed on 34 patients in the goniosynechialysis group,and phacoemulsifieation +intraocular lens (IOL) implantation + goniosynechialysis were carried out in 78 patients of the combination operative group.All the patients were followed-up for 2 years.Vision acuity,intraocular pressure (IOP),anterior chamber depth(ACD),unltrasound biomicroscopy and perimetry were recorded and compared between before and after operation.Results No significant difference was found in vision acuity between preoperation and postoperative 2 years in the goniosynechialysis group ([0.65 ± 0.15] vs.[0.45 ± 0.15]) (t =1.57,P＞0.05),but in the combination operative group,the vision acuity was significantly different between the before and after operation ([0.25±0.15] vs.[0.85 ±0.05]) (t =9.12,P＜0.001).The lOPs at 2 years after operation were (14.2±4.1) mmHgand(13.7±4.8) mmHg,respectively in the goniosynechialysis group and combination operative group and were significantly lower than(47.2 ±6.3) mmHg and(46.9±7.0) mmHg before operation(t =4.95,P＜0.001 ;t=5.03,P＜0.001).The ACD values in the goniosynechialysis group and combination operative group were(3.38±0.02)mm and (3.54±0.03) mm 2 years after operation,which were significantly increased in comparison with (1.33 ±0.24)mm and (1.56±0.37) mm before operation(t=7.65,P＜0.001;t=6.76,P＜0.001).Conclusions Both combination of phacomulsification with goniosynechialysis or 180° goniosynechialysis are effective for the treatment of PACG.Suitable operation should be alternated depending on the indicators of PACG patients.

OBJECTIVETo study the relationship between compositions of hyperuricemia and metabolic syndrome among residents aged > or =20 years.

METHODSA stratified cluster sampling was conducted with 7887 dwellers recruited and examinaed. Blood samples were then collected for serum detection. Available data was analyzed using SPSS 13.0.

RESULTSThe incidence rates of obesity, hypertension and hyperglycemia for hyperuricemia were 53.4% with OR = 2.568 (95% CI: 2.103-3.137), 38.8% with OR= 2.157 (95% CI: 1.856-2.508) and 21.9% with OR = 1.850 (95% CI: 1.552-2.205) respectively. Along with the increase of uric acid, body mass index changed the most followed by triglyceridemia. The change of hyperglycemia for men and cholesterol for women were not prominent. Conclusion The relationship between compositions of hyperuricemia and metabolic syndrome was close, suggesting that hyperuricemia might serve as one of the compositions of metabolic syndrome and could contribute to the prevention and control of cardiovascular and cerebrovascular diseases.

BACKGROUNDDespite technical advances in tools used to facilitate implantation of cardiac resynchronization therapy (CRT) devices, there are many hurdles related mainly to the variation in the anatomy of the coronary veins. One such difficulty is the presence of a very sharply-angulated or tortuous of the lateral or posterolateral cardiac vein.

METHODSTotally 44 patients, 28 males and 16 females, with congestive heart failure and intraventricular conduction delay were studied retrospectively. There were 23 patients who had left ventricular (LV) lead implantation using standard techniques and equipment. For the other 21 patients with LV lead implantation we used the Attain Select II catheter delivery system. The patients were seen every 3 - 6 months for 12 months and the efficacy of the primary procedure, LV lead implantation time, procedure and fluoroscopy time and the complications associated with the two techniques were evaluated.

RESULTSThere were no significant differences in the age, gender, New York Heart Association (NYHA) functional class, ischemic etiology, QRS duration, left ventricular ejection fraction, left ventricular end-diastolic diameter, left ventricular end-systolic diameter and LV dyssynchrony between the two groups. The LV lead implantation time, procedure time and fluoroscopy time were significantly shorter in the group using the Attain Select II catheter delivery system; LV lead implantation time from (51 ± 7) minutes to (40 ± 7) minutes (P < 0.001), procedure time from (143 ± 17) minutes to (124 ± 18) minutes (P = 0.001), and fluoroscopy time from (45 ± 7) minutes to (35 ± 6) minutes (P < 0.001). A successful procedure of LV lead implantation was significantly improved from 17/23 (74%) patients using the standard techniques and equipment, to 20/21 (95.3%) patients using the Attain Select II catheter delivery system (P = 0.06)

CONCLUSIONIt is feasible and safe to implant LV leads through the coronary sinus using the Attain Select II catheter delivery system.

Objective With Landsat TM remote sensing images,snail habitats in Poyang Lake region were identified,using two indices:the modified normalized difference water index (MNDWI) and the normalized difference vegetation index (NDVI).Methods Two Remote sensing images of both wet and drought seasons in Poyang Lake region were obtained.MNDWI and NDVI were extracted from the images respectively,to present the regions of “water in summer and land in winter” and the coverage of vegetation.By overlaying those two regions,the areas of potential snail habitats were drawn.Finally,sensitivities and specificities of the recommended methods were assessed and compared to that of the traditional methods for the sake of extracting the areas of snail habitats.Results The threshold values of MNDWI for the wet and drought seasons were 0.34 and 0.58,respectively and the threshold value for NDVI of the drought season was 0.02.Sensitivity and specificity of our method were 95％ and 100％,respectively,higher than the conventional approach (se.=75％,sp.=100％ ).Conclusion Joint application of MNDWI and NDVI seemed a better method to detect the snail habitats and could be used for the quantitative and automatic surveillance program on snails.

The present study aimed to investigate the mRNA expression levels of collagen, matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinases (TIMPs) in the left and right atria in patients with chronic atrial fibrillation (CAF). Forty five patients with valvular heart disease were sampled in this study, including 18 patients with sinus rhythm (SR), 27 patients with CAF. Clinical data of these patients were collected, and the left and right atrial appendages were obtained from these patients during heart valvular replacement surgery. The mRNA levels of collagen type I, collagen type III, MMP1, MMP9, TMP1 of the atria were then measured by semi-quantitative RT-PCR. The results obtained were as follows. Compared to those in SR group, in atria of CAF group, the mRNA levels of collagen type I, MMP1 and MMP9 increased (P<0.05), while the mRNA level of TMP1 decreased (P<0.01). There were no significant differences in the mRNA levels of collagen type I, collagen type III, MMP1, MMP9 and TMP1 between the left and right atria of SR group (P>0.05). In CAF group, the mRNA level of MMP1 in the right atrium was higher than that in the left atrium (P<0.05), however, the mRNA level of MMP9 in the left atrium was higher than that in the right atrium (P<0.01). In both the left and right atria, the mRNA of collagen type I was positively correlated with the corresponding atrial diameter; the mRNA of MMP1 and MMP9 was positively correlated with the mRNA of collagen type I, and was negatively correlated with the mRNA of TMP1. These results suggest that the increased level of collagen type I associated with selective upregulation of MMP1, 9 and downregulation of TMP1, 9 in the atrium might be the molecular basis of atrial interstitial fibrosis in patients with CAF. Moreover, during CAF development, there is difference in the expression of MMPs between the left and right atria.
