Analysis on the epidemic situation of the hand-foot-mouth disease in Yangpu District of Shanghai from 2006 to 2015 / 上海预防医学

Objective To analyze the epidemiological characteristics of hand-foot-mouth disease (HFMD) in Yangpu District of Shanghai from 2006 to 2015,and to explore the current epidemic situation of HFMD so as to master the trend thereof.Methods The descriptive epidemiological method was applied in analyzing and statistics for the monitored data of HFMD in Yangpu District of Shanghai from 2006 to 2015.Results A total of 11 239 cases of HFMD were reported in Yangpu District from 2006 to 2015, which peaked from April to July.Among the 11 communities of Yangpu District, Jiangpu community and Yinhang community were the ones with more cases.The main patients were kindergarten kids below five years of age as well as children living separately in this area.The relevant results of etiological detection from 2010 to 2015 showed that the rate of patients infected by enteroviruses other than enterovirus EV71 and enterovirus CA16 rose constantly and exceeded the rate of EV71-and CA16-infected patients.Conclusion The HFMD in Yangpu District had distinct seasonal features as well as features of resident crowds.It is recommended that relevant monitoring and preventive work should be done for susceptible children during peak onsets thereof.

Clinical efficacy of narrow band ultraviolet bin combined with yuyin recipe in treating psoriasis vulgaris / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the clinical efficacy of narrow band ultraviolet bin (NB-UVB) combined with Yuyin Recipe (YYR) in treating psoriasis vulgaris (PV).</p><p><b>METHODS</b>One hundred and nineteen patients with PV were randomly assigned to 2 groups by envelop method, the 62 patients in the treated group were treated with NB-UVB and YYR bathing, and the 57 in the control group were treated with NB-UVB alone. The course of treatment for both groups was 8 weeks. PASI scoring was performed before treatment and at the 2nd, 4th, 6th and 8th week of treatment respectively, and the treatment effect was evaluated depending on the decreasing rate of PASI score. The accumulated dose and side-effect of NB-UVB applied was observed.</p><p><b>RESULTS</b>The PASI scores in the treated group measured at various time points after treatment were significantly different to that of baseline (P < 0.05). The cure rate in the treated group and the control group was 69.35% and 24.56% while the total effective rate in them 96.77% and 71.93%, respectively, showing significant difference between the two groups (chi2 = 27.755, P <0.01). The difference of PASI decreasing rate between groups showed statistical significant from the 4th week (P <0.01). The total dose of NB-UVB applied in the treated group (9.95 +/- 4.76) was less than that in the control group (12.77 +/- 5.05) with the difference of statistical significance (t = 3.141, P <0.01). The adverse reaction occurrence in them was 4.84% (3/62) and 31.58% (18/57) respectively, also showing significant difference (chi2 = 119, P <0.01). CCONCLUSION: The combined use of TCM medicated bath with NB-UVB can enhance the curative effect, reduce the accumulated dosage and lessen the adverse reactions of ultraviolet radiation.</p>

Upregulating the expression of angiogenesis-related genes by transplanting autologous mononuclear bone marrow cells into myocardial infarction scar and the periphery / 中华心血管病杂志

<p><b>OBJECTIVE</b>To detect the regulation of angiogenic genes involved in the processes of collateral development.</p><p><b>METHODS</b>Myocardial infarction (MI) scar was induced by cryoinjury in New Zealand rabbits. Four weeks after MI, 24 hours before cell transplantation, bone marrow was aspirated from the right thigh bone and mononuclear bone marrow cells (BMCs) were isolated by Ficoll density gradient centrifugation. Then the mononuclear BMCs (n = 8) or IMDM culture medium (n = 8) were transplanted into infarction scar and the periphery. Four weeks after mononuclear BMCs transplantation, DNA microarray analysis was performed to detect the regulation of angiogenesis-related genes in infarction scar and the periphery. And the differences of angiogenic genes expression were compared among several important growth factors by Western blot.</p><p><b>RESULTS</b>DNA microarray analysis showed the detail regulation of genes involved in the angiogenic processes. There were 15 genes upregulated over 3 times in the infarction scar. In addition, we also found more genes are involved in the process of angiogenesis in its periphery than in the infarction scar (40 genes vs. 15 genes). Western bolt analysis further demonstrated that mononuclear BMCs transplantation was capable of increasing the levels of VEGF, FGF and Angiopoietin-I expression in the infarction scar and its periphery, compared with the control group, P < 0.05.</p><p><b>CONCLUSION</b>These findings indicate that the natural angiogenic processes leading to collateral development are extremely complex, since many kinds of bone marrow-derived growth factors involved in the processes after mononuclear BMCs transplantation into infarction sites.</p>

Differential acetylcholine and choline concentrations in the cerebrospinal fluid of patients with Alzheimer's disease and vascular dementia / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>An important aspect of Alzheimer's disease (AD) is loss or impairment of cholinergic neurons. It is controversial whether there is a similar cholinergic impairment and cerebral deficit of acetylcholine (ACh) in the case of vascular dementia (VD). The purpose of this study was to explore the levels of ACh and choline (Ch) in the cerebrospinal fluid (CSF) of patients with AD and VD, and their possible relationship with cognitive impairment.</p><p><b>METHODS</b>Twenty-two AD patients, twenty-two VD patients, and twenty normal controls were recruited and scored with a Mini-Mental State Examination (MMSE). CSF concentrations of ACh and Ch were measured using high-performance liquid chromatography with an electrochemical detector (HPLC-ECD) and the results were then compared to cognitive status.</p><p><b>RESULTS</b>ACh concentrations in CSF of AD patients [(10.7 +/- 5.1) nmol/L] and VD patients [(16.8 +/- 7.4) nmol/L] were both significantly lower than in controls [(34.5 +/- 9.0) nmol/L, t = 10.67, P < 0.001; t = 6.91, P < 0.001]. Both results correlated positively with MMSE scores (rs = 0.88 and rs = 0.85, respectively, P < 0.01). The CSF concentration of Ch was significantly higher in VD patients [(887.4 +/- 187.4) nmol/L] compared to AD patients [(627.6 +/- 145.1) nmol/L, t = 6.4, P < 0.001] and controls [(716.0 +/- 159.4) nmol/L, t = 4.2, P = 0.002]. CSF Ch concentration showed no difference between AD patients and normal controls, nor did it correlate with MMSE score in any of the three groups.</p><p><b>CONCLUSIONS</b>The positive correlation between ACh deficit and cognitive impairment suggests that ACh is an important neurotransmitter for memory. The similar decrease in ACh concentration in AD and VD patients may imply a similar pathogenesis for the process of cognitive impairment involved in these two disorders. The elevated CSF levels of Ch in VD patients compared to AD patients may be useful diagnostically. Cholinesterase inhibitors may be helpful not only for AD patients, but also for VD patients.</p>
