Chinese Journal of Endemiology 2010;29(4):402-405
Objective This study aims to observe and analyze the result of implementing health management and intervention for chronic Keshan disease treatment. Methods Certain amounts of chronic Keshan disease patients in Keshan disease area were chosen and given health management and treatment intervention including primarily pharmacological treatment for the chronic congestive heart failure together with health education and life style instruction. From 2006 to 2008, three interventions were conducted every six month. Electrocardiogram description, proportion of heart to chest, classification of heart function, types of Keshan disease and labour capacity at the initial and the last stage of the intervention were taken as judging indexes. If one of the indexes was improved then the intervention will be regarded as effective. The number of effective cases and effective rate were counted in order to observe the impact of intervention times and different medicine on intervention results. Results Altogether 345 Keshan disease patients were involved in the study, among them 207 were effective, the effective rate was 60%(207/345). One hundred and eighty were involved in the intervention for once, and the effective rate was 44%(79/180). Ninty-one took part in the intervention twice, and the effective rate was 66%(60/91). Seventyfour attended the intervention for three times, and the effective rate was 92% (68/74). There were significant difference among groups of different intervention times (χ2 = 52.16, P < 0.01), and the effective rate increased with increased intervention times. Three times were higher than that of one or two times (χ2= 15.81, 49.56, all P< 0.0125). Twice were better than once(χ2 = 11.76, P < 0.0125). There were significant difference among groups of different medicine groups(χ2 = 19.56, P< 0.01). Among different medicine groups, the efficacy of angiotensin converting enzyme inhibitor(ACEI) group was the highest 77%(82/106) while the cardiotonic medicine group was 50%(47/94) and cardiac muscle nutrition poisons was 54% (78/145). The efficacy rate of ACEI group was higher than that of cardiotonic medicine group and cardiac muscle nutrition poisons(χ2 = 16.28, 14.71, P< 0.0125). Conclusions The implement of health management and treatment intervention to Keshan disease patients is of great significant in improving the healthy condition of Keshan disease patients. Health education and life-style instruction as well as the use of ACEI, β-blockers and diuretic have comparatively obvious effect on treatment of chronic Keshan disease congestive cardiac failure.

RhoA, a small GTPase, is involved in a wide array of cellular functions in the central nervous system, such as cell motility, cytoskeleton rearrangement, transcriptional regulation, phagocytosis and cell growth. It is not known how spinal cord injury (SCI) affects the expression of RhoA in different nerve cells. In the present study, we investigated the changes of RhoA expression in remote areas of the injury at the 3rd, 7th and 30th day after SCI, which was established by T10 contusion method. Moreover, we examine its expression profile in neurons, astrocytes and microglia. RhoA was found to be weakly expressed in these nerve cells in normal spinal cord. Western blotting showed that, after SCI, the total RhoA expression was up-regulated, and the RhoA expression was increased and peaked at the 7th day. Double immunostaining revealed specific and temporal expression patterns of RhoA in different nerve cells. The expression of RhoA in neurons started to increase at day 3, peaked at day 7 and then decreased slightly at day 30. Expression of RhoA in astrocytes increased moderately after SCI and peaked at day 7. There was no obvious change in RhoA expression in microglia after SCI in remote areas. This study demonstrated that, after SCI, RhoA expression exhibited different patterns with different nerve cells of spinal cord. RhoA expression patterns also changed with time after SCI, and among different nerve cells in the injured spinal cord. These findings can help us better understand the roles of RhoA in SCI.

Objective To discover the reciprocal regulation and its molecular mechanism of estro-gen, IL-6 and IL-8 in ovarian cancer cells. Methods Based on our previous studies, the effect of 17β-estradiol (E2) on the expression levels of IL-6, IL-8 and their respective receptors was investigated. Mean-while, the effect of IL-6/IL-8 on estrogen receptor (ER) expression and estrogen-dependent transcriptional activation was analyzed. Gene expression profile analysis revealed that CAOV-3 and OVCAR-3 cells, which express ER, IL-6 and IL-8 receptors, were suitable models for this study. Results We found that E2 not only enhanced IL-6/IL-8 secretion via NF-κB signaling pathway, but also modulated IL-6 and IL-8 receptors expression. Tamoxifen (Txf), an ER antagonist, completely abolished E2-stimulated IL-6/IL-8 expression. On the other hand, in the absence of estrogen, both cytokines increased ERα expression, decreased ERβ ex-pression, and activated estrogen-dependent transcriptional activation, which was completely blocked by Txf. Pretreatment of OVCAR-3 with p38 MAPK, MEK1/2 or ErbB2 MAPK inhihitors, respectively, IL-6-media-ted ER activation was blocked, while IL-8-indueed ER activation was blocked by Src inhibitor. Conclusion These data suggest that estrogen, IL-6 and IL-8 may form a mutual amplifying signaling which contributes to the growth and development of ovarian carcinoma.

Objective Controversies remain as to the recovery time, recovery quality, and incidence of peri-recovery adverse reactions of the patient receiving general anesthesia with remifentanil and sufentanil.This study aimed to systematically assess the qual-ity of recovery from general anesthesia with remifentanil and sufentanil. Methods Randomized controlled trials ( RCTs) were re-trieved from The Cochrane Library, PubMed, MEDLINE, EMbase, Ovid, Springer, Web of Science, CNKI, CBM, VIP, and Wan-Fang Data.According to the modified Jadad quality scale, the literature retrieved was screened and subjected to quality evaluation and meta-analysis was performed on the included studies using the RevMan 5.1 software. Results Thirty-three RCTs involving 2175 pa-tients were finally included.The results of meta-analysis showed no significant differences between the remifentanil and sufentanil groups undergoing thyroid surgery either in the recovery time to spontaneous breathing ( T1) and eye-opening ( T2) and endortracheal extubation time ( T3 ) ( P >0.05 ) or in the incidence rate of postoperative nausea and vomiting (PONV) (P>0.05).T1, T2 and T3 were significantly shorter in the sufentanil than in the remifentanil group in other types of surgery (P<0.05).The patients with level-1 Ramsay score were remarkably more in the remifentanil than in the sufentanil group ( MD =13.67, 95% CI 2.67 -69.91 ) ( P <0.05), and the VAS scores were markedly higher in the former than in the latter group at 30 minutes (MD=3.37, 95% CI 3.28-3.46) and 1 hour after extubation (MD=2.53, 95% CI 2.43 -2.63) (P<0.05). Conclusion Compared with sufentanil, remifentanil provides a quicker recovery but a weaker analgesia effect and a higher rate of post-operative agitation.However, sufentanil produces a better pain relief and a higher quality of recovery after operation.

Background Recently,there were many studies on corneal innervations during mammalian development.However,there were fewer studies on discussing corneal innervations before and after mouse eye openings.Objective The present study was to investigate the change in the regulation of corneal nerve fiber length and density before and after mouse eye openings to offer a basis for clinical research in human.Methods Thirty SPF C57BL/6 mice were divided into postnatal 1 day(P1 d),P7 d,P13 d(1 day before eye opening),P14 d(eye halfopened),P17 d(1 day after eye opening)and P23 d(7 day after eye opening)groups,with 5 mice and 10 eyes for each group.Entire corneal stretches were prepared and immunostaining with an anti-neuron-specific β-Ⅲ tubulin antibody was performed to label the corneal nerve fibers.Confocal microscopic pictures from the corneal dorsal-nasal region (DN),dorsal-temporal(DT),ventral-nasal region(VN)and ventral-temporal(VT)were taken using Delta Vision Core.From these pictures,the mouse corneal area,total length and density of nerve fibers in the 4 regions were calculated.The use of the animals complied with Statement of ARVO.Results Corneal areas of P1 d,P7d,P13 d,P14 d,P17 d and P23 d mice were(0.404±0.007),(1.362±0.154),(1.573±0.080),(1.603±0.046),(1.847±0.052),(2.445±0.798)mm2,respectively ; the total lengths of nerve fibers were(3.718±1.044),(19.065±3.350),(23.687±0.907),(27.309±2.477),(31.989±3.976),(41.214±1.573)mm,respectively ; the densities of nerve fibers were(9.592±1.138),(14.506±1.908),(15.088±1.241),(16.772±1.897),(16.821±2.102),(17.660±1.216)mm/mm2,respectively,all showing significant increases with age(F =22.906,P =0.000 ; F =0.424,P =0.000 ; F =2.375,P=0.000).A positive correlation of the increasing corneal areas and increasing lengths of nerve fibers was found(r=0.983,P<0.01).Nerve fiber densities in the four corneal regions significantly increased with age(DN region:F =0.159,P =0.000 ; DT region:F =2.1 72,P =0.001 ; VN region:F =1.998,P =0.000 ; VT region:F=2.352,P=0.000).From P13 d to P14 d,the corneal nerve fiber densities in the DN region decreased by 6.0% without significant difference(t =0.589,P =0.572); and the corneal nerve fiber densities in the DT region,VN region and VT region decreased by 4.6%,5.5% and 0.1%,respectively,without significant difference from P14 d to P17 d(t=0.549,P=0.596;t=0.701,P=0.501 ;t=-0.100,P=0.919).Conclusions The development of nerve fibers in the whole cornea or the four corneal regions is influenced by eye opening in mouse to various extents.From P13 d to P14 d,the corneal nerve fiber densities in the DN region decreased by 6.0% without significant difference.From P14 d to P17 d,the corneal nerve fiber densities in the DT region,VN region and VT region decrease by 4.6%,5.5% and 0.1%,respectively,without significant difference.Afterwards,the growth of nerve fibers increased in pace and the growth rate is recovered.
