ABSTRACT

Objective: To observe the clinical efficacy of acupoint pressure plus long-snake moxibustion for upper-limb spastic hemiplegia after cerebral infarction. Methods: A total of 100 patients were randomized into a control group and an observation group, with 50 cases in each group. Both groups were treated with the same conventional internal medicine and rehabilitation training. The control group was treated with additional acupoint pressure therapy, and the observation group was treated with long-snake moxibustion on the basis of the treatment given to the control group. The Ashworth grade, Fugl-Meyer assessment upper limb scale (FMA-UL) and Barthel index (BI) were evaluated, and the root mean square (RMS) values of biceps brachii and flexor carpi radialis on the affected side were measured before and after treatment. The efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the Ashworth grade of the observation group was superior to that of the control group (P<0.05). The scores of FMA-UL and BI in both groups increased compared with those before treatment (all P<0.05), and the scores of FMA-UL and BI in the observation group were higher than those in the control group (both P<0.05). The RMS values of biceps brachii and flexor carpi radialis in both groups decreased compared with those before treatment (all P<0.05), and the RMS values of biceps brachii and flexor carpi radialis in the observation group were lower than those in the control group (both P<0.05). Conclusion: Based on conventional internal medicine and rehabilitation training, acupoint pressure plus long-snake moxibustion has great therapeutic efficacy for upper-limb spastic hemiplegia after cerebral infarction. It can improve the degree of spasticity of the affected upper limb, reduce the muscle tone of biceps brachii and flexor carpi radialis on the affected side, and enhance the mobility of the affected limb and the activities of daily living.

ABSTRACT

In this study, we examined the inhibitory effects of lupeol, an extract of Euphorbia fischerana Steud, on human breast cancer MDA-MB-231 cells migration and invasion. Lupeol was found to inhibit the invasion of MDA-MB-231 in the cell adhesion assay, transwell test and wound healing assay. The expression of cyclooxygenase-2(COX-2), matrix metalloproteinase-2(MMP-2), -9(MMP-9) and nuclear transcription factor-kappa B (NF-κB) p65 in breast cancer following treatment with different concentrations of lupeol was analyzed with Western blot. Lupeol inhibited the migration and invasion of MDA-MB-231 cells in a dosedependent manner in vitro (PκB p65 levels was significantly down-regulated. These observations suggest that lupeol can inhibit the abilities of invasion of MDA-MB-231 cells by inhibiting the protein expression of COX-2, MMP-2 and MMP-9. Its mechanism may be related to inhibition of the nuclear NF-κB signal pathway.

ABSTRACT

The research aimed to investigate the therapeutic effects and mechanisms of Opuntia dillenii Haw polysaccharide (OPS) on atherosclerosis of rats. First atherosclerotic rat models were established by high-fat and high-calcium diet. Thirty days later, the rats were treated with low dosage of OPS (0.2 g x kg(-1) x d(-1)) or high dosage of OPS (0.4 g x kg(-1) x d(-1)) by intraperitoneal injection for 60 days continuously. At the end of treatment, thoracic aorta rings were prepared and vasorelaxation of rat thoracic aorta in different experiment groups were determined by using 620M multi wire myograph system in vitro. Blood and livers of rats were collected. Then plasma levels of total cholesterol (TC), triglyceride (TG) and low density lipoprotein (LDL) of rats were separately determined using whole automatic biochemical analyzer; protein level of hepatic apolipoprotein B (ApoB) and that of hepatic diglyceride acyltransferase (Dgat1) were measured by Western Blot technique. Results showed that the ability of rat thoracic aorta to relax decreased markedly in the model group compared with that in the normal group, and significant differences existed in vasorelaxation ratios induced by different concentrations of carbamylcholine chloride (Carb) between these two groups (P < 0.01). After OPS treatment, the ability of rat thoracic aorta to relax improved markedly, the vasorelaxation ratios induced by Carb at 5 and 10 μmol x L(-1) were respectively 0.34 ± 0.08 and 0.62 ± 0.15 in the group treated with low dosage of OPS, while the ratios induced by Carb at 1 and 5 μmol x L(-1) were respectively 0.54 ± 0.08 and 0.98 ± 0.02 in the group treated with high dosage of OPS, which were all significantly different with those in the model group (P < 0.01). Plasma contents of TC, TG and LDL reduced significantly by the treatments both with low and high dosages of OPS compared with those in the model group (P < 0.01). Protein level of hepatic ApoB and that of hepatic Dgat1 decreased significantly after the treatment with high dosage of OPS compared with those in the model group (P < 0.01). These results indicate that OPS can markedly improve the vasorelaxation of thoracic aorta of atherosclerotic rats and has significant anti-atherosclerotic effect; inhibiting the expression of ApoB and Dgat1 and thus decreasing the amounts of TC, LDL and TG serving as one of the molecular mechanisms of its antiatherosclerosis effect.

ABSTRACT

In view of that there is no report of west Nile virus infection cases in our country, evaluation the self-prepared anti-WNV-IgG diagnostic ELISA kit should be employed with the establishment of the serum sample panel collected from the entry personnel. All individuals of entry personnel were traveled from epidemic area of infectious west Nile disease. In our study, the serum samples were both detected by self-prepared anti-WNV-IgG diagnostic ELISA kit and the FDA certified kits ,which are FOCUS West Nile Virus IgG Dxselect and Panbio Dengue IgG Capture ELISA kits. The self-prepared kit and FDA certified kits were compared and assessed simultaneously. Furthermore, the specificity, repeatability and stability of the kits were also evaluated. The results indicated that no significant difference of detective rates (35. 6% for self-prepared kit vs. 32.5% for FOCUS kit, χ2 = 3. 05, P > 0.05) and good consistency (Kappa = 0.8372) between the self-prepared kit and FDA certified kits. Also, the positive coincidence rate, the negative coincidence rate and the total coincidence rate were calculated as 91.18%, 95.34% and 92.66%, respectively. The laboratory self-developed kit presented similar quality as the counterpart kits with FDA certificate. The development of our self-prepared anti-WNV-IgG diagnostic ELISA kit will provide technical support for the prevention and control of west Nile virus entry.

ABSTRACT

<p><b>BACKGROUND</b>Ablation of complex fractionated atrial electrograms (CFAE) is an important adjunctive therapy in atrial fibrillation (AF). The present study was to elucidate the substrate underlying CFAE.</p><p><b>METHODS</b>Nine adult mongrel dogs were involved in the present study. AF was induced through rapid atrial pacing with vagosympathetic nerve stimulation. CFAE was recorded during AF. Ablation was performed at CFAE sites. Based on the location of the ablation scar, the atrial specimens were divided into CFAE and non-CFAE sites. Serial sections of the atrium were stained respectively with hematoxylin-eosin (HE) and the general neural marker protein gene product 9.5 (PGP9.5). We compared the characteristics of the myocardium and the ganglionated plexus (GPs) distribution between the CFAE and non-CFAE sites.</p><p><b>RESULTS</b>The myocardium of non-CFAE sites was well-organized with little intercellular substance. However, the myocardium in the CFAE site was disorganized with more interstitial tissue ((61.7 ± 24.3)% vs. (34.1 ± 9.2)%, P < 0.01). GPs in the CFAE site were more abundant than in non-CFAE sites ((34.45 ± 37.46) bundles/cm(2) vs. (6.73 ± 8.22) bundles/cm(2), P < 0.01).</p><p><b>CONCLUSION</b>The heterogeneity of the myocardium and GPs distribution may account for the substrate of CFAE and serve as a potential target of ablation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the promoter methylation levels of p15, CDH1, DAPK and HICI genes of patients with myelodysplastic syndrome (MDS) and explore the relationship between the level of methylation and clinical features.</p><p><b>METHODS</b>DNA methylation levels of p15, CDH1, DAPK and HICI in peripheral blood (PB) or bone marrow (BM) samples from 52 MDS patients were detected by real-time quantitative PCR. The correlation of the methylation level with clinical features and hematological findings was analyzed. 38 de novo AML patients and 46 normal individuals served as controls.</p><p><b>RESULTS</b>The methylation levels of p15, CDH1, DAPK and HICI were 16.23 ± 21.69, 6.59 ± 9.39, 0.14 ± 0.11 and 7.81 ± 9.70 in BM, and 14.96 ± 20.16, 6.00 ± 9.26, 0.12 ± 0.14 and 6.74 ± 9.72 in PB, respectively from 18 MDS patients, and the difference between BM and PB was not statistically significant (P > 0.05). The methylation levels of p15 (14.70 ± 18.17) and CDH1 (6.61 ± 8.79) genes in high risk (RAEBI/II) MDS were significantly higher than in low risk (RCMD/RARS/5q-, p15: 1.99 ± 1.59, CDH1: 1.23 ± 1.14 and RCMD, p15: 3.02 ± 3.42, CDH1:1.53 ± 2.06) MDS or control (p15: 1.69 ± 1.82, CDH1: 1.01 ± 1.12) (P < 0.05). The methylation levels of DAPK gene had no difference among subtypes of MDS, and that of HIC1 gene only differed between RAEB I/II (9.16 ± 11.95) and control (2.49 ± 2.26) (P = 0.042). The difference of methylation levels of p15, CDH1, DAPK and HICI in BM was statistically significant among subtypes of MDS (P = 0.001, 0.003, 0.039, 0.023, respectively). And so did of p15 and DAPK in PB (P = 0.013, 0.006, respectively). The methylation level of p15 and CDH1 was significantly correlated with IPSS classification and blasts percentage in BM.</p><p><b>CONCLUSIONS</b>p15 and CDH1 genes are special hypermethylation genes in MDS. Methylation level of HIC1 gene showed an upward tendency from low risk to high risk MDS.</p>

ABSTRACT

Objective To investigate the iodine nutrition status of the target population living in the areas with low coverage rate of iodized salt and to provide a basis to prevent and control iodine deficiency. Methods The investigation was carried out in the areas with coverage rate of iodized salt lower than 80%, including 7 counties (city, district). Three townships(sub-district office) were sampled in each county and two elementary schools in each township(sub-district office). Urinary iodine level was measured for 40 children aged from 8 to 10 years old in each elementary school. Drinking water iodine was collected and determined in their living villages. Twenty salt samples were tested for iodine in salt from 20 house which had fertile women, and urine iodine of 10 fertile women were tested in each village. Results Sixty-two water samples were determined and the water iodine was ranged from 5.8 to 272.7 μg/L, of which 3 water samples were equal and more than 150 μg/L. Eight hundred and seventy-two salt samples were collected. The coverage rate of iodized salt was 70.74%(585/827) and the coverage rates were below than 80% in 5 counties (city, district). A total of 1660 children' urine samples were collected, the content of urine iodine ranged from 10.0 to 1088.0 μg/L and the urine iodine median was 173.7 μg/L. Four hundred and thirty-seven urine samples were collected from the fertile women and the urine iodine median was 179.1 μg/L. The iodine level of children and women was the highest in Dongguang County(251.8,273.8 μg/L) while that of Hejian County (130.8,118.7 μg/L) was the lowest. Conclusions Although the iodine nutrition of children and fertile women is appropriate in areas with low coverage rate of iodized salt, we presume from the results that the possibility of iodine deficiency in pregnant and lactating women exists in Hejian and Anping.
