Objective To investigate the clinical value of 99Tcm-MIBI gated G-MPI in detecting the myocardial damage in sarcoglycanopathy.Methods 99 Tcm - MIBI G - MPI was performed in 8 patients (3 males,5 females,age ranged from 10 to 30 y) with sarcoglycanopathy confirmed by clinical results and molecular pathology and 4 healthy persons as control group.Quantitative gated SPECT (QGS) software was used for processing and interpretation.Myocardium of left ventricle was divided into 7 segments and 20 subsegments.A five-point scoring system was used to evaluate the myocardial damage.Results Seven patients showed positive results in G-MPI (7/8).Fifty-nine sub-segments of injured myocardium were detected in the 140 sub-segments of 7 abnormal patients.One abnormal segment was observed in 1 patient,two abnormal segments were detected in 2 patients,and ≥3 abnormal segments were observed in 4 patients.Enlarged left ventricles were detected in 5 patients (5/8),and the LVEF of 3 patients among them decreased to (43.1 ±2.8)％.Conclusion 99Tcm-MIBI G-MPI can detect myocardial damage in sarcoglycanopathy as a direct and non-invasive method,and can be used in the early diagnosis and long-term follow-up in sarcoglycanopathy.

OBJECTIVETo study the effects of biological clock protein on circadian disorders in hypoxic-ischemic brain damage (HIBD) by examining levels of CLOCK and BMAL1 proteins in the pineal gland of neonatal rats.

METHODSSeventy-two 7-day-old Sprague-Dawley (SD) rats were randomly divided into sham-operated and HIBD groups. HIBD model was prepared according to the modified Levine method. Western blot analysis was used to measure the levels of CLOCK and BMAL1 in the pineal gland at 0, 2, 12, 24, 36 and 48 hours after operation.

RESULTSBoth CLOCK and BMAL levels in the pineal gland increased significantly 48 hours after HIBD compared with the sham-operated group (P<0.05). There were no significant differences in levels of CLOCK and BMAL proteins between the two groups at 0, 2, 12, 24 and 36 hours after operation (P>0.05).

CONCLUSIONSLevels of CLOCK and BMAL1 proteins in the pineal gland of rats increase significantly 48 hours after HIBD, suggesting that both CLOCK and BMAL1 may be involved the regulatory mechanism of circadian disorders in rats with HIBD.

OBJECTIVEThis study aimed to understand the prevalence rate, epidemiological characteristics and relevant factors of arthritis in Shanghai.

METHODSA sample of 7 575 residents aged 15 years and above was drawn from 6 communities under multiple stage cluster sampling. A household survey with questionnaire was carried out to differentiate both undiagnosed patients and those with definite arthritis. Those who had not been diagnosed before were asked to carry further clinical examinations by a rheumatologist.

RESULTSThe prevalence rate of arthritis was 6.11%, including osteoarthritis (OA) 4.18%, rheumatoid arthritis (RA) 0.52%, gout 0.28%, ankylosing spondylitis (AS) 0.28%, rheumatic arthritis 0.49% and other types arthritis 0.82%. Arthritis was significantly related to cardiovascular disease, pulmonary disease and gastrointestinal disease. Age, female and obesity might serve as risk factors for arthritis. Physical labors and living in rural area might have protecting effects.

CONCLUSIONElderly and female seemed to be at high risk for arthritis. Weight control and more exercise should be encouraged to reduce the risks. For arthritis patients, treatment to other chronic diseases should not be ignored.

OBJECTIVETo explore the effect of Changji'an Capsule (CA) on mRNA expressions of neuropeptide Y (NPY) in the hypothalamus and colon and serum levels of adreno-cortico-tropic hormone (ACTH) in rats of diarrhea predominant irritable bowel syndrome (IBS-D) model rats.

METHODSTotally 48 SD rats were randomly divided into six groups, i.e., the normal control group, the model group, the Pinaverium Bromide group (PB, 0.018 g/kg), the high dose CA group (2.812 g/kg), the medium dose CA group (1.406 g/kg), and the low dose CA group (0.703 g/kg), 8 in each group. The IBS-D rat model was established by using separation of breast milk + stimulation of acetic acid + constraint of four limbs. Normal saline was given to rats in the normal control group and the model group. All medication lasted for 14 successive days by gastrogavage. The serum content of ACTH was detected by enzyme linked immunosorbent assay (ELISA). The expressions of NPY mRNA in the colon and the hypothalamus were detected using real-time fluorescence quantitative PCR.

RESULTSCompared with the normal control group, the serum ACTH content significantly increased (P < 0.01), the NPY mRNA expression in the colon and the hypothalamus obviously decreased (P < 0.01) in the model control group. Compared with the model group, the serum ACTH obviously decreased in the high dose CA group, the medium dose CA group, and the PB group (P < 0.01, P < 0.05). The NPY mRNA expression in the colon and the hypothalamus were obviously up-regulated in the high dose CA group, the medium dose CA group, the low dose CA group, and the PB group (P < 0.05).

CONCLUSIONSCA could modulate the abnormity of brain-gut axis of IBS-D rats possibly by up-regulating NPY mRNA expressions in the hypothalamus and the colon and down-regulating the ACTH content in the hypothalamic-pituitary-adrenal axis.

[To explore the effect of Humifuse Euphorbia Herb ( HEH) on alleviating insulin resistance in type 2 diabetic KK-Ay mice. Totally 40 KK-Ay mice fed with high-fat diet were divided into four groups: the metformin group, the model group, the HEH low-dose group and the HEH high-dose group, and orally administrated with metformin hydrochloride (250 mg x kg(-1)), distilled water, humifuse euphorbia herb 1 g x kg(-1) and 2 g x kg(-1). Besides, C57BL/6J mice with ordinary feed were taken as the normal control group and orally administrated with equal distilled water. The oral administration for the five groups lasted for eight weeks. Before and after the experiment, weight, fasting glucose and insulin tolerance were determined. The morphological changes in pancreas were observed through hematoxylin-eosin (HE) staining on pancreatic tissue sections. The serum insulin, TNF-α, IL-6, adiponectin (ADPN) and leptin (LEP) were detected by ELISA. The results showed that HEH could reduce weight and fasting glucose in KK-Ay mice, alleviate hyperinsulinemia, reduce blood glucose-time AUC, increase 30-min blood glucose decline rate, relieve insulin resistance, significantly ameliorate the pathomorphological changes in pancreas in each group, decrease serum TNF-α, IL-6 and leptin levels in KK-Ay mice and rise serum ADPN level. This study proved that humifuse euphorbia herb can ameliorate the insulin resistance in KK-Ay mice, and its mechanism may be related to the effect on inflammatory factors and adipocytokines.
