Objective To study the association between activity of hand,foot and mouth disease (HFMD) and the meteorological factors in Suzhou.Methods A total of 17 653 children diagnosed with HFMD in Children's Hospital Affiliated to Suzhou University during 2008 to 2011 were enrolled.The meteorological factors in(c)luding mean temperature,relative humidity,rainfall amount,sum of sunshine and mean wind velocity during Jan 2008 to Dec 2011 were collected monthly.Numeration data were analyzed using chi square or Fisher exact test.Normal distribution data were analyzed using Pearson correlation and non-normal distribution data were analyzed using Spearman rank correlation.Results HFMD could be found all over the year and had obvious seasonality which peaked in Summer,followed by Spring and Autumn and HFMD decreased markedly in Winter.The activity of HFMD was positive correlated with mean temperature(r=0.716,P＜0.01),wind velocity (r=0.630,P＜0.01),rainfall(r=0.477,P＜0.01) and sum of sunshine(r=0.311,P＜0.05).No statistical significance was observed between relative humidity and HFMD(r =0.276,P＞0.05).Multivariate stepwise regression analysis showed that only mean temperature and rainfall were associated with HFMD and mean temperature had stronger influence on HFMD than rainfall (t =4.687,P ＜ 0.01 ; t =2.258,P ＜ 0.05).Conclusions HFMD has obvious seasonality.Mean temperature and rainfall are the main factors affecting this seasonality.

ObjectiveTo observe the efficacy of wrist-ankle acupuncture plus auricular point sticking in treating pre-exam anxiety syndrome.MethodSixty patients with pre-exam anxiety syndrome were randomized into a treatment group to receive wrist-ankle acupuncture plus auricular point sticking (30 cases, 11 cases dropped out) and a control group to receive auricular point sticking (30 cases, 1 dropped out). In the treatment group, the bilateral Upper 1 zones were punctured regarding the wrist-ankle acupuncture, and for the auricular point sticking, Heart (CO 15), ear Shenmen (TF 4), Endocrine (CO 18), Adrenal Gland (TG 2p), Subcortex (AT 4) were selected. In the controlgroup, the same auricular points were treated. For both groups, the intervention began from 1 week prior to the exam, 3 d as a treatment course, and the therapeutic efficacy was evaluated after 2 successive courses. The Sarason Test Anxiety Scale (TAS) and autonomic function test were used to assess the anxiety severity before and after treatment. ResultThe total effective rate was 84.2% (16/19) in the treatment group versus 82.8% (24/29) in the control group, and the difference was statistically insignificant (P>0.05). The TAS score dropped significantly in the control group after intervention (P<0.01).ConclusionWrist-ankle acupuncture plus auricular point sticking and auricular point sticking alone both can effectively improve the symptoms of pre-exam anxietysyndrome.

Objective To identify the effect of both high glucose and high insulin on miR-145 level.Methods The human vascular smooth muscle cells ( VSMCs) were cultured and the proliferation of VSMCs was induced by high glucose and high insulin medium.The samples were divided into 4 groups: normal group, high glu-cose group (25 mmol/L), high insulin group (300 mU/L), high glucose and high insulin group.The ex-pression of miR-145 in VSMCs was assayed by real-time PCR.Proliferation of VSMCs was determined by MTT method After 72 h cultivation.The migration of VSMCs was analyzed by cell scratch test .VSMCs in each group was transfected by miR-145 virus ( lentiviral vector ) .Proliferation and migration were assayed after 48 h transfection.Results The expression of miR-145 in VSMCs of other three groups was decreased ( P<0.05 ) , especially the expression in the high glucose and insulin group was the lowest ( P<0.01 ) .Prolifera-tion and migration of VSMCs was promoted by high glucose and/or high insulin medium.Under fluorescent, transfection rate of VSMCs was about 80%after 48 h transfection.Proliferation and migration of VSMCs in each group after transfection were significantly lower than before ( P<0.05 ) .Conclusions High glucose and high in-sulin could decrease the expression of miR-145 in VSMCs, The overexpression of miR-145 may inhibit the prolif-eration and migration of VSMCs .

Objective:To explore the epidemiological characteristics and the antibiotic resistance of Streptococcus pneumoniae isolates, and to provide the evidence for the rational use of antimicrobial agents to treat Streptococcus pneumoniae infection. Methods:The positive microbiological laboratory identification and antimicrobial susceptibility testing of Streptococcus pneumoniae from sputum of children with respiratory infections during January 2010 to December 2017 in Children′s Hospital of Soochow University were retrospectively analyzed. The positive rates of Streptococcus pneumoniae of different genders, ages, years and seasons were compared. The annual detection rates and trends of drug resistance of Streptococcus pneumoniae to penicillin, amoxicillin and cefotaxime were analyzed by Mann-Kendall trend test. The seasonal decomposition of time series was conducted to assess the association between Streptococcus pneumoniae detection rate and season. Enumeration data was compared using χ2 test. Results:Of the 88 480 sputum specimens, the total positive rate of Streptococcus pneumoniae was 10.3%(9 081/88 480). The detection rates of Streptococcus pneumoniae in children aged 0 to <0.5 years old, 0.5 to <2 years old, 2 to <3 years old, 3 to <5 years old, and 5 to <15 years old were 4.2%(1 407/33 224), 13.1%(3 191/24 390), 14.9%(2 417/16 252), 17.9%(1 474/8 246) and 9.3%(592/6 368), respectively. The difference was statistically significant ( χ2=2 421.6, P<0.01). The detection rates were 8.1%(1 321/16 306) from January to March, 10.9%(2 194/20 207) from April to June, 8.5%(2 141/25 058) from July to September, and 12.7%(3 425/26 909) from October to December. The discrepancy of positive rates in different seasons showed statistical significance ( χ2=311.5, P<0.01). During 2010 to 2017, significant decreases in antibiotic resistant rates of Streptococcus pneumoniae to penicillin, amoxicillin and cefotaxime were detected (tau=-0.93, -0.93 and -0.71, respectively, all P<0.05). Conclusions:The detection rate of Streptococcus pneumoniae in sputum of children with respiratory infections may present seasonal pattern and vary between different ages of children. The resistance to β-lactam antibiotics has declined.

Objective: To observe the effect of reinforcing and reducing manipulation by breathing on yin and yang meridian points for motor function of knee joints in patients with ischemic stroke. ＜br> Methods: A total of 60 ischemic stroke cases were randomly allocated into an observation group and a control group, 30 in each group. Other than basic and conventional rehabilitation therapies, cases in the observation group were treated with reinforcing and reducing manipulation on yin and yang meridians points for a period of 8 weeks; whereas cases in the control group only received the same basic and conventional rehabilitation therapy as that in the observation group. Then the knee joint energy, support moment and shaking moment were compared between the two groups before treatment, and after 4-week and 8-week treatment respectively. ＜br> Results: Before treatment, there were no between-group significant differences in knee joint energy, support moment and shaking moment (all P>0.05). After treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved (P＜0.05). After 8 weeks of treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved than that of 4-week treatment (P＜0.05). In addition, there were between-group statistical significances in comparing knee joint energy, support moment and shaking moment after 4 and 8 weeks of treatment (P＜0.05). ＜br> Conclusion: Reinforcing and reducing manipulation by breathing on yin and yang meridian points can increase the knee joint support and shaking force and moment in stroke patients and improve their walking ability.

Objective To observe the change of extension-flexion arc of ankle in hemiplegia due to ischemic stroke after yin-yang acupuncture associated with respiration needling manipulations.Method Sixty ischemic stroke patients were divided into a control group and a treatment group by random number table, 30 in each group. The control group was intervened by basic treatment, while the treatment group was by yin-yang acupuncture associated with respiration needling manipulations in addition to the basic treatment. Before intervention and 28 d after intervention, the Lokomat gait analysis system was adopted to observe the change of the extension-flexion arc of ankle respectively under motorial and stationary states.Result When heel was grounded, the flexion angle, the maximum extension-flexion arc value, and motility of ankle joint of the treatment group were statistically different from those of the control group (P＜0.05).Conclusion Yin-yang acupuncture associated with respiration needling manipulations can effectively improve the movement and the walk function of hemiplegia due to ischemic stroke.

Objective To observe the effect of yin-yang acupuncture in association with respiratory reducing-reinforcing needling manipulations on the gait cycle in patients with post-stroke hemiplegia. Methods Sixty patients with ischemic stroke were randomized into a treatment group and a control group, 30 each. The control group was intervened by conventional medication, while based on which the treatment group was additionally given yin-yang acupuncture in association with respiratory reducing-reinforcing needling manipulations. The kinematic time parameters were evaluated before intervention and after 28-day treatment. Results After intervention, the stance phase of the affected side and the healthy side, ambulation cycle, swinging phase of the affected side and the healthy side, and the stance phase of both limbs in the treatment group were significantly different from that in the control group(P＜0.05). Conclusion Yin-yang acupuncture in association with respiration reducing-reinforcing needling manipulations can effectively improve the gait cycle and ambulation function of the patients with post-stroke hemiplegia.
