3.Primary culture and hepatocelluar specific protein expression in human amniotic epithelial cells
Journal of Shanghai Jiaotong University(Medical Science) 2006;0(03):-
Objective To optimize the method of primary culture for human amniotic epithelial cells (AECs) and detect the expression of hepatocelluar specific proteins in AECs. Methods AECs were obtained by collagenase and trypsin digestion method. 10,20,40 ng/mL epidermal growth factor (EGF) and 10 ng/mL basic fibroblast growth factor were added separately to the culture media,inverted microscope was used to observe the cell growth and proliferation,and the optimal condition for primary culture of AECs was obtained. The primary cells cultured without growth factors were served as controls. The expression of hepatocelluar specific proteins such as albumin,cytokeratin-18 (CK-18),alpha-1 antitrypsin (AAT) and alpha-1 foetoprotein (AFP) in cultured cells and histological sections were detected by immunohistochemical staining. Results The AECs available were relatively pure,with only a few mesenchymal cells. EGF of 10 ng/mL was chosen as an ingredient of culture medium as the growth and proliferation of AECs significantly accelerated with 10 ng/mL EGF. The expression of albumin,CK-18,AAT and AFP was detected in amnion tissues and AECs cultured in vitro. Conclusion Collagenase and trypsin digestion method and culture medium with 10 ng/mL EGF are favourable conditions for primary culture of AECs. Hepatocelluar specific proteins are expressed in human amnion tissues and AECs cultured in vitro,indicating that AECs have some characteristics of hepatocytes.

Objective To explore the effect of the thyroid morphologic change,the initiating treatment time and the thyroid function(serum FT_4,TSH)on mental development in children with congenital hypothyroidism (CH).Methods After diagnosed,52 cases of CH were orally administrated with L-T_4,then their mental and physical development were monitored and thyroid morphologic changes were observed by thyroid imaging(~(99m)TcO_4) and type B ultrasonography.The Bayley test was performed at the age of 10 to 30 months and expressed as mental developmental index(MDI)and psychomotor developmental index(PDI).Analysis was conducted upon treatment timing and thyroid morphologic changes.Results The MDI in those cases with morphologic abnormalities treated within 90 days was significantly lower than that with normal morphology(91?20 vs 105?15,P

Objective:
To learn the epidemiological characteristics of infectious disease related public health emergencies in Zhejiang Province from 2010 to 2018 for the prevention and control.
Methods:
The surveillance data was extracted from National Public Health Emergency Management Information System. Descriptive epidemiology method was used to analyze main diseases as well as distribution characteristics of time and places.
Results:
A total of 445 events were reported, which caused 14362 cases and 34 deaths, with a attack rate of 0.69% and mortality rate of 0.24%. There were 298 events with less than 30 cases, accounting for 66.97%. The event classification was dominated by general events ( 242 events, 54.38% ) and ungraded events ( 201 events, 45.17% ). The main diseases were chickenpox ( 134 events, 30.11% ), hand foot mouth disease ( 59 events, 13.26% ) and other infectious diarrhea ( 51 events, 11.46% ). The incidence peaked from April to June ( 129 events, 28.99% ) and from November to December ( 131 events, 29.44% ). Ningbo ranked the top in the number of reported events ( 141 events, 31.69% ). Most events ( 322 events, 72.36% ) occurred in schools.
Conclusions
The infectious disease related public health emergencies in Zhejiang Province from 2010 to 2018 were mainly caused by chickenpox, hand-foot-mouth disease and other infectious diarrhea. The two peaks of the emergencies occurred from April to June and from November to December. Ningbo was the main area reporting infectious diseases, and schools were the main places.

Objective To explore the therapeutic effects of canal wall-down tympanoplasty(CWdT)on chronic otitis media and evaluate the effects of simultaneous auditory rehabilitation.Methods 13 cases on chronic otitis media with cholesteatoma and/or granulation tissue were treated by CWdT,the effects were contrast with radi- cal mastoidectomy.Results After 6 months to 6 years of follow-up,all the cases by CWdT had dry ear without re- currence.The rate of hearing restoration and improvement was 84.6% from the cases.In same times,the rate of re- currence,hearing restoration and improvement was 52.6%,31.0% from the mastoidectomies.Conclusion The CWdT has advantage in indication,removal of lesions and the operation could be adjusted appropriately for simulta- neously auditory rehabilitation.
