Objective In order to provide a large quantity of retinal pigment epithelial cells (RPE cells) in vitro, we want to estab-lish method for culturing pig RPE cells. Methods RPE cells were separated with trypsin and cultured in vitro. The cells were identified by immunohistochemical staining with anti-human keratin and transmission electron microscope (TEM). Results Cultured RPE cells gradually presented transparent and fusiform shape. Immunohistochemical staining demonstrated that the cells were stained by anti-human keratin, and the cultured cells showed typical ultrastructure of RPE cells. Conclusion The cultured cells may be the foundation of pig RPE cells.

Objective To evaluate the feasibility of combined application of helicobacter pylori stool antigen(HpSA)-and traditional serology in epidemiologic study of helicobacter pylori(Hp) infection in children. Methods Hp serum IgG antibodies were examined among 480 healthy children. Heticobacter pylori stool antigen(HpSA) were measured among children who were seropositive. Hp status was defined as positive when stool antigen test was positive, Hp status was defined as negative when seronegative. A case - control study was conducted to identify risk factors of Hp infection in preschool children. Results Among 480 preschool children, 172 (35 8 %) were sero- positive, 64(13.3 %) with positive result of HpSA test were diagnosed as current Hp infection. Univariate factor analysis demonstrated that Hp infection clustered in families and Hp infection was often acquired in childhood by oral-oral and fecal - oral person to person transmission. Conclusions HpSA and serology screening are two nomnvasive tests, simple not costly, effective and accurate. The combination of these 2 noninvasive methods can be applied in epidemiologic study of Hp infection in childrenJAppl Clin Pediatr,2004,19(11):948-950

The distribution of ABH substances in human tissue cells was studied using the specific red cell adherence test(SRCA test).Tissues were taken from 11 cadavers of known ABO type and secrete status,fixed with 10% neutral formalin,Isolated abdominal skins kept in room temperature for 1～13 days were also observed for the purpose of studing the influence of the time elapsed after death on SRCA test results ABH substances were found in mucous membranes,mucous glands and prostate glands.ABH substances in those tissues were controlled by secrete status.ABH substances were also found in endothelia of blood vessels,stra- tified epithelia,acinar cells of pancreas and sweat glands.We firstly found that ABH substances were present in epithelia of pulmonary alveoli and epi- thelia of small bile duct in liver. Using SRCA test,the ABO blood type were correctly demonstrated in 11 isolated abdominal skins kept in room temperature for 1～13 days.

Objective To comprehend the etiology and the clinical characteristics of hypereosinophilia.Methods The clinical data of 53 patients with hypereosinophilia admitted to Peking Union Medical College Hospital from November 1992 to February 2005 were analyzed.Results The causes of reactive hypereosinophilia included allergic diseases,infections,connective tissue diseases,malignant diseases,lung diseases,eosinophilic gastroenteritis.idiopathic hypereosinophilic syndrome had longer course of disease;more organ involved than reactive causes.The incidence of lymph node enlargement,spleen enlargement and thrombus was higher than the reactive.IHES had higher level of white blood cell count,absolute eosinophilic count,IgG and CRP.Conclusion The etiology and clinical characteristics of hypereosinophilia are various,so the differential diagnosis of hypereosinophilia is very important.

Objective To explore the the effect of psychological intervention on emotion and postoperative bladder spasm in elderly patients with benign prostatic hyperplasia. Methods 40 elderly cases with benign prostatic hyperplasia were classified as the control group and were given the routine intervention, the other 40 cases were received psychological intervention at the basis of routine intervention and classified as the observation group. The two groups were treated in Anji county traditional Chinese medicine hospital from September 2015 to January 2017. Results The anxiety and depression in the 2 groups had no significant difference before intervention, and the prognosis in the observation group was better than that in the observation group after intervention. The bladder spasm in the two groups was compared. The third days after the operation, the incidence of bladder spasm in the observation group was 10.0%, which was significantly lower than 45.0% in the control group, and the difference between the 2 groups was statistically significant (P<0.05). Conclusion Psychological intervention has better effect on mood and bladder spasm in elderly patients with prostate hyperplasia. It can help patients to improve their emotional state, reduce anxiety and depression, and ultimately reduce the incidence of bladder spasm, which is worthy of clinical reference.

Objective To study the clinical effect of small incision cataract extraction in the treatment of acute angle-closure glaucoma with cataract.Methods Fifty-eight patients with acute angle-closure glaucoma combined with cataract were selected,and according to the digital table they were randomly divided into two groups:control group and observation group.The patients in the control group were treated by conventional method.The patients in the observation group were treated with small incision cataract.The changes of intraocular pressure,anterior chamber depth and visual acuity before and after treatment were observed.The incidence of complications and the satisfaction of treatment were compared between the two groups.Results There were no significant differences in IOP,visual acuity and anterior chamber depth between the two groups before treatment(all P>0.05).After treatment,the intraocular pressure,anterior chamber depth and visual acuity of the observation group were (10.2±4.0)mmHg,(3.3±0.5)mm,(0.85±0.08),respectively,which of the control group were (17.5±5.0)mmHg,(3.2±0.5)mm and (0.50±0.06),respectively.The improvement of intraocular pressure and anterior chamber depth of the observation group was more significant than the control group(t=0.120,0.520,1.012,all P<0.05).The satisfaction rate of the observation group(96.6%) was higher than that of the control group(75.8%)(χ2=9.823,P<0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion Small incision cataract extraction is an effective treatment for acute angle-closure glaucoma complicated with cataract,and the postoperative complications are less.The patients are satisfied with the treatment and deserve to be popularized.

Objective To study the curative effect of traditional chinese medicine combined with noninvasive ventilation on respiratory failure in patients with acute exacerbation of chronic obstructive pulmonary disease.MethodsThe patients were divided into experimental group (n=37) and control group (n=37).The experimental group was treated with traditional chinese medicine combined with noninvasive ventilation.The control group was treated with noninvasive ventilation method.The heart rate, blood gas analysis index, ventilation index and complication were compared between the two groups before and after treatment.ResultsAfter treatment, the levels of PaO2 in the two groups were not significantly different.The heart rate and PaCO2 of the experimental group were significantly lower than those of the control group, while the pH value and SaO2 were significantly higher than those in the control group (P< 0.05), and the total incidence of complications was 21.62%, which was significantly lower than that of the control group (64.86%, P<0.05).The time of infection control window, the highest PEEP and the time of mechanical ventilation were significantly shorter than those of the control group (P< 0.05).ConclusionThe treatment of patients with acute exacerbation of chronic obstructive pulmonary disease(COPD) combined with noninvasive ventilation therapy can significantly improve the heart rate and blood gas analysis indexes, and optimize the noninvasive ventilation efficiency, control lung infection as soon as possible, shorten the time of noninvasive ventilation and reduce the side effects that noninvasive ventilation brought about.
