RESUMEN
AIMS: To explore the effects of a Traditional Chinese Medicine health educational intervention on the quality of life and self-care agency of elderly patients living with chronic cardiovascular disease. BACKGROUND: Cardiovascular disease is a leading cause of morbidity and mortality worldwide. The secondary prevention and treatment for chronic cardiovascular disease emphasize the importance of lifestyle modification. However, behavior-changing is difficult and individual choices are influenced by broader environmental factors. The lifestyle intervention for the purpose of self-care enhancing should be considered the driving force from the cultural element. METHODS: The study was conducted from April 2014 to October 2014. Ninety-eight community dwelling individuals with chronic cardiovascular disease were recruited from Shaoxing and randomized. 48 participants were in the intervention group with a 6-month Traditional Chinese Medicine health education and 50 participants were in the control group with routine care. The main measurements included health-related quality of life and self-care agency, which was assessed by the Short Form-36 Chinese version and the Exercise of Self-Care Agency Scale respectively, and were measured at the baseline and post intervention (6months after baseline). RESULTS: After 6months of intervention, the quality of life and self-care agency in the intervention group were significantly improved. CONCLUSIONS: The traditional Chinese medicine health education is an effective method for promoting quality of life and self-care agency in cardiovascular disease patients. It could be applied as adjunctive care for cardiovascular disease patients self-care supporting.

OBJECTIVE: To investigate the protective effect of curcumin analogue L6H4 on the kidney from the type 2 diabetic rats. METHODS: Twenty-four SPF male SD rats were randomly divided into 3 groups(n=8):normal control group(NC),diabetes mellitus group(DM) and DM+L6H4-treatment group(DT). After rats were fed with high-fat diet for 4 weeks, both the DM and DT groups were injected with streptozotocin intraperitoneally to induce type 2 diabetes mellitus models. The rats in DT group were given L6H4 by gavage at the dose of 0.2 mg/kg·d for 8 weeks. After the treatment, the 24 h urinary protein, fasting blood glucose (FBG), triglyceride (TG), serum creatinine(Scr),blood urea nitrogen (BUN) and uric acid (UA) were detected biochemically. The pathological changes of the kidneys were observed under light and transmission electron microscopes. The expressions of TGF-ß1, FN and Col IV were detected by immunohistochemistry. RESULTS: The levels of the 24 h urinary protein, FBG, TG, Scr and BUN were elevated significantly in diabetic group(P<0.01). The glomerular volume of DM group rats became irregularly enlarged, diffused mesangial matrix accumulated, with basal membrane proliferous hypertrophy and fusion phenomenon of foot process, the expressions of TGF-ß1,FN and Col-IV were elevated significantly (P<0.05). After treated with L6H4, the levels of the 24 h urinary protein, FBG, TG, Scr and BUN were decreased in DT group compared to DM group (P<0.01), the morphological changes of kidney were ameliorated. The expression levels of TGF-ß1, FN and Col-IV were downregulated (P<0.05). CONCLUSIONS: L6H4 exerts the protective effect on kidneys of type 2 diabetic rats by reducing expression of TGF-ß1, inhibiting secretion of Col-IV and FN, relieving the deposition of the extracellular matrix.

Sestrin2 is involved in a different cellular response to stress conditions. However, the function of Sestrin2 in the cardiovascular system remains unknown. In the present study, we tested whether Sestrin2 has a beneficial effect on macrophage cell apoptosis induced by oxidized low-density lipoprotein (oxLDL). We found that oxLDL induces expression of Sestrin2 in RAW264.7 cells in a time-dependent and dose-dependent manner. We also found that knockdown of Sestrin2 using small RNA interference promotes cell apoptosis and reactive oxygen species production induced by oxLDL. In addition, our results show that the c-Jun NH(2)-terminal kinase (JNK)/c-Jun pathway is activated by oxLDL. Inhibiting the activity of the JNK pathway abolishes the increase of Sestrin2 induced by oxLDL. These findings suggest that the inductive effect of Sestrin2 is mediated by the JNK/c-Jun pathway. Our results indicate that the induction of Sestrin2 acts as a compensatory response to oxLDL for survival, implying that stimulating expression of Sestrin2 might be an effective pharmacological target for the treatment of lipid-related cardiovascular diseases.

OBJECTIVE: To investigate the effects and mechanisms of diethylhexylphthalate (DEHP) on morphology and function of progenitor Leydig cells (PLC) in rats. METHODS: Twenty pregnant SD rats were randomly divided into 4 groups ( n = 5): normal control group, DEHP low dose group , middle dose group, and high dose group, which were treated from postnatal day (PND) 1 to PND 21 of the pubs with DEHP at the doses of 0, 10, 100, 750 mg/(kg · d) in 0.5 ml of corn oil by gavage respectively. At the end of the treatment, the male pups were killed and blood samples were collected for determination of serum testosterone concentration by chemiluminescence method. The body weight, testis weight and anogenital distance (AGD) were measured. The morphology of PLC was observed by light and transmission electron microscopy. The protein expression of steroidogenic acute regulatory protein(StAR) in PLC was determined by immunohistochemistry. The mRNA expression of insulin-like growth factor-I (IGF-I) in the testis was assayed by real-time PCR. RESULTS: Compared with normal control group, the serum testosterone and AGD of male pubs from the middle and high dose groups were declined significantly (P < 0.01), the testis weight and body weight from high dose group were decreased significantly (P < 0.01), while the testis weight increased in the low dose group (P < 0.05). Under light microscope, PLC showed hyperplasia and cluster aggregation in the low dose group and focal hyperplasia in the middle and high dose group. The spermatogenic cells in seminiferous tubules showed decrease, apoptosis and unfix in the high dose group. Under transmission electron microscope, the PLC showed decreased lipid droplets, smooth endoplasmic reticulum and mitochondriae in the treated group. The mRNA expression of IGF-I increased in the low dose group, and the protein expression of StAR decreased in the middle and high dose group. CONCLUSION: Lactating exposure to DEHP may interfere with the synthesis of testosterone of PLC in male pubs, the decrease of StAR and the damage of PLC may be involved in it.

OBJECTIVE: To investigate the protective effect and mechanism of curcumin derivatives B06 on myocardium from type 2 diabetic rats. METHODS: Thirty-five male SD rats were randomly divided into 5 groups, normal control group (NC group), high fat group (HF group), high fat treatment group (FT group), diabetes mellitus group (DM group) and diabetes treatment group (DT group) (n = 7). The late four groups were fed with high fat food, after four weeks of high fat feeding, the rats from DM group and DT group were injected with low dosage of streptozocin intraperitoneally to induce diabetes mellitus, FT group and DT group were gavaged with curcumin derivatives B06 at the dosage of 0.2 mg/kg x d. The blood glucose and lipid were detected biochemically, blood insulin was assayed by ELISA and the insulin resistance index was calculated, the morphology of myocardium was observed by light and transmission electron microscopy, the protein expression of AMP-activated protein kinase alpha (AMPKalpha) and phosphorylated AMP-activated protein kinase alpha (p-AMPKalpha) in myocardium were tested by Western blot. RESULTS: The level of blood glucose, lipid, insulin and the insulin resistance index were increased in HF group and DM group, but they were decreased after the treatment with B06. The expression of AMPKalpha and p-AMPKalpha were decreased, but they became increased after the treatment of B06. There were increased collagen fibers in interstitium and expansion of mitochondria in cytoplasm of myocardium from DM group, but they were ameliorated in B06 treatment group. CONCLUSION: It is suggested that B06 may relieve the damage of myocardium from type 2 diabetic rats and the increased expression of AMPKalpha and p-AMPKalpha may be involved in it.

OBJECTIVE: To explore the correlation between mental disorder and craniocerebral injury, and notifying its related risk factors. METHODS: 342 patients from Sep. 2008 to Sep. 2012 with craniocerebral injury were selected and related clinical data on general their conditions, including sex, age, educational level, satisfaction on careers and relations to family were collected. All the patients received CT-scans to the head, IQ test, MQ test, SCID-1/P, PDQC and SCICP detection. Multivariate logistic regression was used to analyze the general information and cerebral injurious conditions of patients regarding the incidence of mental disorders. RESULTS: 249 patients with mental disorder were noticed out of the total 342 patients with craniocerebral injury, with the incidence rate as 72.8% including 117 depression (47.0%), 95 anxiety disorders (38.2%), 27 mania (10.8%), 69 intelligence and memory disorders (27.7%) cases. Data from correlation analysis showed that factors as sex, age, educational level, satisfaction on careers and family of patients as well as type, severity and location of the craniocerebral injuries appeared to have important correlation with mental disorder. RESULTS: also showed that the age of patients (OR > 1.04), severity and location of the craniocerebral injuries (OR1 > 1.28, OR2 > 1.31) were independent risk factors (P < 0.05). CONCLUSION: The age of patients, severity and location of the craniocerebral injuries were independent risk factors for mental disorder in patients with craniocerebral injury.

AIMS: Omentin-1 (also known as intelectin-1) is a recently identified visceral adipose tissue-derived cytokine that is inversely related to obesity. Our previous study showed that omentin-1 inhibits osteoblastic differentiation of calcifying vascular smooth muscle cells (CVSMCs) in vitro. This study was undertaken to investigate the effects of omentin-1 on arterial calcification and bone metabolism in vivo. METHODS AND RESULTS: In vitro, omentin-1 stimulated production of osteoprotegerin (OPG) and inhibited production of receptor activator for nuclear factor κB ligand (RANKL) in both CVSMCs and osteoblasts. In vivo, adenovirus-mediated over-expression of omentin-1 attenuated arterial calcification and bone loss in OPG(-/-) mice. All these in vitro and in vivo actions were abrogated by blockade of the PI3K-Akt signalling pathway. Furthermore, omentin-1 reduced serum levels of RANKL, tartarate-resistant acid phosphatase-5b and osteocalcin, all of which are increased dramatically in OPG(-/-) mice. CONCLUSION: These data suggest that omentin-1 ameliorates arterial calcification and bone loss in vivo through the regulation of the RANK signalling pathway.
