Background and purpose:Increasing thyroid cancer (TC) incidence has caused wide public concern. It is typically interpreted as an increase in the true occurrence of TC but may also relfect changing life style or aging of population or increased diagnostic scrutiny. This study describes the temporal trend for incidence of TC and survival rate of patients by summarizing the 41 years TC incidences and follow-up data in Xuhui District, Shanghai.. Methods:Annual TC incidence data of Xuhui District from 1973 to 2013 were provided by Shanghai Cancer Registry System. The calculation of age-standardized incidence rates (ASIR) was based on the population of the year 1973. Temporal trends in TC incidence were analyzed based on the natural spline regression model. Annual percentage change (APC) was estimated by Jointpoint software from US National Cancer Institute, as well as survival rates were estimated using Kaplan-Meier method by Stata software.Results:During the period from 1973 to 2013, papillary cancer was the dominant type with proportion 69.8%. The ASIRs for female TC were 2.51-2.70 times as high as those for male TC. The average age of TC incidence for male was 50.04±14.71 while for female was 48.57±13.65. When aging factors were removed, incidence rate of TC was on the rise since 1981 with the APC of 8.46% (95%CI: 5.9%-11.1%), and on a rapid growth from 2004 to 2013 with the APC of 20.30% (95%CI: 9.8%-31.7%). The study showed that the 5-year TC survival rate was 95.21%, and the 10-year TC survival rate was 89.09%. In addition, survival rate of female was higher than that of male (χ2=15.43,P=0.000 1).Conclusion:The rising trend of TC in Xuhui District is similar to those in Shanghai and some developed countries. Although the mortality rate of TC is low, it has a rapid increase in incidence. Studies on factors associated with TC will help to clarify the epidemiological features about TC and promote more eff-cient prevention and control strategies.

BACKGROUND: Child neglect is one of the most important aspects of child abuse and has become a serious problem influencing children's development all over the world. Therefore, it is necessary to nderstand the current conditions and influential factors of child neglect and establish effective evaluation methods in China.OBJECTIVE: To investigate the current conditions and influential factors of urban child neglect in Suzhou city.DESIGN: A comparative analysis of sampling survey.SETTING: Department of Children's Health Care, Soochow University Affiliated Children's Hospital.PARTICIPANTS: This study was conducted in one public kindergarten and two private kindergartens of urban areas in Suzhou city between March and October 2003. Totally 370 children (196 boys and 174 girls) aged between 4 to 6 years old without obvious physical and mental diseases were voluntarily investigated, and they had been living with the person that answered the questionnaire regarding to child neglect in China in the recent 1 year. METHODS: Questionnaire regarding to child neglect in China was sent to each volunteer.he questionnaire evaluates the current conditions of child neglect by 20 items of 5 aspects including physical care (buy fruit for child, consider the nutritional need of child, care about the body height and body mass of child), emotional care (chat with child, play and tour with child, encourage child to do the things whatever they can, listen to what the child feels, introduce the child to the guests when they come to your home, let him or her stop immediately when child cries, care about the activities in kindergarten), education care (buy books for child, tell stories to child, recognize and correct the bad behavior of child, answer the questions asked by child seriously), safety care (protections against fire and electricity at home, warn child against matches, knives and other sharp things, teach child how to cross the road) and health care (prepare the common medicine for child at home, urge child to brush teeth, correct the bad posture). The volunteers were asked to answer each question objectively according to the conditions of child within the recent 1 year, and each question should be answered by selecting only one choice (never, occasionally, usually, always), and anyone should not be omitted. Meanwhile,the educational background and occupation of the parents were also investigated.MAIN OUTCOME MEASURES: The general status of child neglect and the effects of different family educational background and occupation of parents on child neglect were observed. RESULTS: Totally 370 questionnaires were sent out, and 370 qualified ones were recollected, the effective rate was 100%. ① In Suzhou city, the children were given better regards and good care in the aspects of education, medicine and safety, but neglects on children's physical and mental care still exists in a few families. ② Families of different educational background could think highly of the medical care, safety and psychical care of children, but neglects on education and emotional development more commonly existed in the families with the educational background under university. ③ All the families with different occupation could think highly of the medical care, safety and physical care of the children, but education and emotional development were better in the cadre families than in the ordinary families.CONCLUSION: In Suzhou city, the children are given better regards and good care in the aspects of education, medicine and safety, but some bad manifestations of child neglect exist in education and emotion, which are associated with the educational background and occupation of the parents.Further studies about the evaluation, prevention and intervention are needed for child neglect in China.

Objective To evaluate the effect of gamma irradiation on the proliferation,differentiation,and mineralization of murine osteoblastic cells,and to investigate the related molecular mechanism.Methods Osteoblastic cells were irradiated by different doses (0,0.5,1.0,2.0,5.0 Gy)of 137Cs γ-rays.Cell morphology was observed with a microscopy,cell viability was analyzed by MTT assay,and ALP activity was analyzed by the methods of enzyme histochemistry and PNPP.Meanwhile,gene expressions of ALP,osteocalcin (OC),collagen Ⅰ,osteoprotegerin (OPG) and receptor activator of nuclear factor-kB ligand (RANKL) were measured by semi-quantified RT-PCR.Results Cell viability decreased with the radiation doses over 1.0 Gy ( t =6.197 - 18.677,P ＜ 0.05 ).After radiation with a dose over 2.0 Gy,the cell number and the junctions of cell protrusions decreased,the cells had low refractivity and the activity and mineralization ability of ALP were also inhibited ( t =2.790 -2l.374,P ＜0.05).In addition,the expressions of ALP and OC mRNA were down-regulated significantly (t =3.563 -16.508,P ＜ 0.05) when the radiation dose was higher than 0.5 Gy,and the expressions of OPG,OPG/RANKL mRNA were down-regulated ( t =12.942,4.954,P ＜ 0.05 ) at 5 Gy.But the expressions of collagen Ⅰ and RANKL mRNA were not affected by irradiation.Conclusions The osteoblastic cells were significantly influenced by γ-irradiation,including morphological changes,inhibition of cell proliferation,differentiation and mineralization ability. Meanwhile,mRNA expressions of ALP and OC were downregulated.OPG/RANKL may be a main pathway of osteoblastic cell damage under high dose radiation.

Objective To investigate the clinical characteristics and risk factors for healthcare-associated infection (HAI)in patients with severe chronic hepatitis B (CHB),and provide theoretical basis for preventing and controlling HAI.Methods Retrospective survey was used to investigate the occurrence of HAI in hospitalized patients with severe CHB in a hospital between January 2012 and January 2015,risk factors for HAI were analyzed. Results A total of 126 patients with severe CHB were investigated,49 patients developed 106 times of HAI, incidence of HAI was 38.89%.The main HAI site was respiratory tract (n=47,44.34%),the next was abdominal cavity (n=34,32.08%).A total of 76 isolates of pathogens were detected,gram-negative bacteria,gram-positive bacteria,and fungi accounted for 53.95%(n =41 ),43.42%(n =33),and 2.63%(n =2)respectively.Risk factors for HAI in patients with severe CHB were patients ’ age ≥ 60 years, length of hospital stay ≥ 30 days, complications,invasive operation,serum albumin < 35 g/L,and white blood cell count (WBC)< 4 × 109/L. Conclusion Incidence of HAI in patients with severe CHB is high,the majority are respiratory tract and abdominal cavity infection,risk factors are old age,long length of hospital stay,invasive operation,hypoalbuminemia,and low WBC count.

OBJECTIVETo observe the effect of Qiju Dihuang Pill (QDP) on changes of Chinese medical syndrome types in pregnant women of Gan-Shen yin deficiency syndrome (GSYDS), and to explore the correlation between imbalanced cytokine levels and GSYDS.

METHODSThis was a random controlled trail. A total of 163 pregnant women of GSYDS at 12 -16 gestational weeks were randomly allocated into the experimental group (86 cases) and the control group (77 cases). Patients in the experimental group took QDP for 2 -4 weeks. Changes of Chinese medical syndrome types and serum interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) levels were observed and compared between the two groups before and after treatment.

RESULTS(1) Totally 41 patients (47.7%) in the experimental group were transformed to normal Chinese medical syndrome type. In the same period of the follow-ups, 9 patients (11.7%) in the control group were transformed to normal Chinese medical syndrome type, showing statistical difference (P < 0.05). (2) In the experimental group, the serum level of IFN-gamma and the ratio of IFN-gamma/IL-4 in the peripheral blood were obviously lower after treatment than before treatment (P < 0.01), and obviously lower than those in the control group (P < 0.01). The level of IL-4 after treatment in the experimental group was higher than that before treatment, and also higher than that in the control group, but with no statistical difference.

CONCLUSIONSThese results indicated that there was imbalanced IFN-gamma/IL-4 ratio in the peripheral blood of pregnant women of GSYDS. QDP might play a role in immunoregulation by affecting the IFN-gamma level.

BACKGROUND: Fish oil is one of mainly natural resources of n-3 fatty acids, which can inhibit cardiac allograft vasculopathy (CAV) and prolong the survival of cardiac allograft. But, the mechanism is unclear. Recent in vitro data suggested that n-3 fatty acids could inhibit the release of inflammatory transmitter by the activation of peroxisome proliferator-activated receptor-y (PPARy). OBJECTIVE: To test the hypothesis that n-3 fatty acids from fish oil ameliorates CAV development via activating PPARy. METHODS: A total of 6 Lewis rats and 18 Fisher344 rats were randomly selected as heart donors. An additional 24 Lewis rats were randomly and equally divided into 4 groups. In isograft group, heart transplantation was performed among Lewis rats, without any drug. In low-dose fish oil-treated group, F344→Lewis transplantation was performed. At 1 day following surgery, 0.03 mL/kg fish oil was treated by gavage for 8 weeks. In high-dose fish oil-treated group, F344→Lewis transplantation was conducted. At 1 day following surgery, 0.06 mL/kg fish oil was treated by gavage for 8 weeks. In control group, F344→Lawis transplantation was conducted. Cyclosporine A was administrated by gavage for 8 weeks. In the low-dose and high-dose fish oil-treated groups, cyclosporine A (1.5 mg/kg) was given daily by intramuscular injection for 2 weeks following surgery. CAV was evaluated by histological examination. Activity of nuclear factor (NF) k-B and PPARy was assessed in homogenate. Contents of monocyte chemoattractant protein-1 and interferon-inducible protein 10 were measured by enzyme-labeled immunosorbent assay (ELISA). Chemokine receptor CCR2 and CXCR3 expression was determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). RESULTS AND CONCLUSION: All 24 receptor Lewis rats were survived following surgery. The donor heart could regularly beat at 8 weeks following transplantation. Compared with the isograft group, severe CAV was detected in the control group al 8 weeks. Compared with the control group, CAV was significantly relieved, the activity of PPARy was significantly elevated, the activity of NF k-B was significantly decreased, levels of intragraft monocyte chemoattractant protein-1 and interferon-inducible protein-10 were significantly reduced in the low-dose and high-dose fish oil-treated groups (P < 0.001, P < 0.05), especially in the high-dose fish oil-treated group (P < 0.05). There was no significant difference in expression of chemokine receptors CXCR3 in the low-dose and high-dose fish oil-treated groups and control group. Our results demonstrated that n-3 fatty acids from fish oil can attenuate CAV development, possibly through activating PPARy and subsequently inhibiting the NF-kB activation, the chemokines secretion and its receptor expression in a dose-dependent fashion in rat models.

Objective To investigate the expression of nestin, a type Ⅵ intermediate filament protein in the glomeruli with foot process effacement and the potential relationship between nestin expression in the kidney and the degree of proteinuria. Method Immunohistochemistry was used to determine the localization of nestin in the kidney samples obtained from needle biopsies of normal human and patients with minimal change disease (MCD). Puromycin aminonucleoside (PAN) nephrosis rat models were established by a single intraperitoneal injection of PAN. Both real time quatitative reverse PCR and Western blot methods were applied to evaluate the levels of nestin expression at day 1, 4, 10 and 20 after PAN injection. Results Immunohistochemistry showed that the expression of nestin in glomeruli of MCD patients was significantly reduced compared with normal samples (0.93±0.08 vs 1.65±0.12, P<0.05) . The mRNA and protein expressions of nestin in the rat kidney were transitorily increased by 1.23 folds and 1.48 folds of control group (NC) after 1 day of PAN injection (P<0.05), then decreased quickly in the following days. The mRNA levels of nestin in the kidney were 35.8% and 12.1% of NC after 4 days and 10 days of PAN injection, respectively, (P<0.01) as determined by real time PCR. After 20 days of PAN injury, nestin mRNA expression partly recovered to 65.8% of NC (P< 0.05 ). The protein levels of nestin detected by Western blot presented the similar trend, which were 77.0%, 58.0% and 83.4% of NC after 4 days, 10 days and 20 days of PAN injection, respectively (P<0.05). The degree of proteinuria in puromycin aminonucleoside nephrosis rats was negatively correlated with both mRNA and protein levels of nestin in the kidney(r=-0.667,P<0.05 and r=-0.621 ,P<0.05, respectively). Conclusions The expression of intermediate filament protein nestin is down-regnlated in the kidney characterized with foot process effacement and negatively correlated with the degree of proteinuria in puromycin aminonucleoside nephrosis rats. Nestin may play a potential role in modulating the structure and function of podocyte.

Objective To study the effect of the exogenous recombinant human FGF-basic with different concentrations upon inducing human adipose-derived stem cells (hASCs) to differentiate into adipose cells,and the optimum concentration of exogenous rh-bFGF by experimental research.Methods hASCs were isolated and extracted by enzymatic digestion from the liposuction aspirate.hASCs using adipogenic supplement were divided into experimental group and blank group:the experimental group of adipogenic supplement was divided into adding the exogenous rh-bFGF 10 ng/ml,20 ng/ml and 40 ng/ml,the blank group of adipogenic supplement was cultured without exogenous rh-bFGF.MTT method was used to detect the adipocytes proliferation.The oil red O staining was used in the qualitative analysis on the time of newly forming adipocyte cells.Western blot was used to detect the effects of rh-bFGF on the expression of lipid droplets surface protein CIDEC at different stages during the culture.Results The experimental group could obviously shorten the period of inducing hASCs to differentiate into adioicytes,and promote the proliferation of adipocytes.The formation rate and the proliferation of adipocytes in the group adding 40 ng/ml rh-bFGF were superior to those in the experimental group else and blank group.The average time of the newly formed lipid droplets by adding 40 ng/ml rh-bFGFwas (11.5±1.9)h.The average absorbance of cell proliferation by adding 40ml rh-bFGF was 0.52 ±0.10.The CIDEC expression quantity of adding 40 ng/ml rh-bFGF group was also superior to that in the experimental group and blank group.Conclusions rh-bFGF in hASCs adipogenic supplement could promote the proliferation of adipocytes and dramatically accelerates the program of hASCs differentiating to adipocytes,in which the optimum concentration of rh-bFGF is 40ng/ml.

Objective To investigate the effects of social support intervention on anxiety and depression of pulmonary hypertension(PH)patients,then provide a scientific basis for nursing of patients with pulmonary hypertension.Methods The general condition of PH questionnaire,self-rating anxiety scale (SAS),self-rating depression scale(SDS),social support rating scale(SSRS)were distributed to 131 patients with PH.Then make statistical analysis of patients'anxiety,depression and social support conditions.Results The score of anxiety and depression psychological conditions of patients with pulmonary hypertension was significantly higher than normal population,the difference wag statistically significant.Among 131 patients,16 patients with anxiety,accounting for 12.21% ;21 cases of patients with depression,accounting for 16.03% .28 patients at a high level of social support,92 patients at a medium level of social support,11 patients at a low level of social support,a total of 91.60% of the patients in the middle and higher levels of social support.Anxiety and depression scores had significant negative correlation with social support,objective support points and subjective support points.The anxiety,depression difference among different types of pulmonary hypertension was statistically significant.The difference of anxiety and depression scores between patients with idiopathic pulmonary arterial hypertension and patients with pulmonary hyper tension caused by congenital heart disease were significant.The depression scores between pulmonary hy pertension caused by pulmonary veno-occlusive disease and congenital heart disease were significantly different.Conclusions When nurses care pulmonary hypertension patients.those with different types of PH should be given targeted social support.Attention should be paid to transfer the source of social support to help them adopt a positive attitude to face the diseabe,then improve the treatment and care compliance of patients.
