The morphological and molecular identifications of Cyclospora-like oocysts of dogs were underwent in the present study, in which the morphological characteristics of the Cyclospora-like oocysts firstly found in the stool samples of dogs, such as shape, size, acid-fast staining,sporulation and auto-fluorescene, were observed. According to the published sequence of the rDNA gene of Cyclospora in GenBank, 3 primers were designed and were used to amplify part of the 18S rDNA gene of dog-associated Cyclospora-like organism by nested PCR.The amplicons were purified and cloned into vector pMD19T. Then, the positive clones screened were sequenced and subjected to sequence homology and phylogenetic analysis. It was found that the morphological charactertistics of the Cyclospora-like oocysts in dogs were similar to that of the human Cyclospoa oocysts and the size of-the amplified fragment of 18S rDNA was proved to be 715 bp, that was identical to that of the target fragment. Based on the results of sequence homology and phylogenetic analysis, the dog-associated Cyclospora-like organism was identified as the Cyclospora species.

Objective Objective To investigate the relationship between choroidopathy and integrated backscatter(IBS) of choroid in diabetes mellitus(DM) patients.Methods Eighty DM patients of 158 eyes were divided into 3 groups by the course of diabetic retinopathy(DR)-DM patients without DR group,DM patients with the background DR,DM patients with the proliferative DR.80 normal persons of 160 eyes were the control group.Their IBS values were measured on nose side,temple side and middle side of choroid by HP Sonos 5500,and the correction IBS values(IBS％) were calculated.Results With the deterioration of DR,the IBS and IBS％ of choroid increased.The statistical significance difference were found in various groups(P ＜ 0.01).Conclusions With the deterioration of diabetic choroidopathy,the IBS and IBS％ increased.The IBS technique is useful method to assess the diabetic choroidopathy.

Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P

Objective To investigate the clinical features and the clinical effects of extracorporeal membrane oxygenation(ECMO) in children with fulminant myocarditis. Methods The data of one hundred and sixty one pediatric patients with fulminant myocarditis at Beijing Children′s Hospital from March 1,2007 to May 31,2018 were analyzed retrospectively,including clinical manifestations,electrocardiogram,echocar￣diography,myocardial enzyme,the application of ECMO,curative effect and prognosis. Results Among 161 cases of children with fulminant myocarditis,74 cases (46. 0%) had respiratory tract symptoms,54 cases (33. 5%) had digestive tract symptoms,24 cases (14. 9%) had nervous system symptoms,only 33 cases (20. 5%) had cardiovascular symptoms. One hundred and thirty￣two cases(82. 0%) had elevation of crea￣tine kinase isoenzymes( CK￣MB) and/or cardiac troponin I( cTnI),and 107 cases(66. 5%) had abnormal echocardiography. One hundred and fifty￣two cases ( 94. 4%) showed abnormal electrocardiogram, and the changes of ST￣T and atrioventricular block were most common. Five cases survived in 8 children treated with ECMO. They underwent ECMO with an median supporting time of 101. 5 (52. 75,142. 8) hours through a venous￣arterial ECMO model. After the application of ECMO,blood pressure,the heart rate and oxygen satura￣tion were obviously improved in the 8 children,and the level of blood lactic acid was statistically reduced com￣pared with that before the application of ECMO(P<0. 001). During the follow￣up period of 1 months,the 5 surviving children recovered with normal cardiac function,without abnormal function of other organs. There were a total of 17 cases(10. 6%) died,4 children(8. 9%) in 45 patients died since the application of ECMO and the other 13 children(11. 6%) in 116 patients died before that time. This proportion of death was reduced after the application of ECMO,whereas the difference was not statistically significant(P>0. 05). Conclusion Our study indicates the diverse symptoms in children with fulminant myocarditis. Comprehensive application of electrocardiogram,echocardiography,and myocardial enzymology markers may be of benefit to the timely diag￣nosis of fulminant myocarditis. The application of ECMO in fulminant myocarditis remains an effective approach in reduction of mortality rate,and can effectively support recovery of cardiopulmonary functions.

OBJECTIVETo survey patients with chronic hepatitis B (CHB) to determine their perceptions of CHB-related quality of life (QOF) and to determine the factors influencing this measure.

METHODSA total of 268 patients with CHB (disease group) and 205 healthy individuals (control group) completed the World Health Organization (WHO)QOL-BREF life assessment survey and a self-designed questionnaire of health and QOL. The groups' responses were comparatively analyzed by the cluster sampling method and the independent samples t-test. The strength of influence of each factor on the patients' perceptions of QOL was determined by multiple stepwise regression and one-way ANOVA.

RESULTSThe disease group had significantly lower scores than the control group for overall QOL (62.88 ± 8.22 vs. 67.31 ± 5.82), the physiological area (PHYS: 64.71 ± 15.05 vs. 73.21 ± 11.26), the psychological area (PSYCH: 64.35 ± 14.71 vs. 68.94 ± 10.13), the social relations area (SOCIL: 67.20 ± 12.98 vs. 69.83 ± 8.65), the environmental area (ENVIR: 59.58 ± 13.23 vs. 63.97 ± 10.24), the QOL self-assessment (60.75 ± 21.54 vs. 66.90 ± 17.57) and the health self-assessment (58.13 ± 19.15 vs. 76.26+/-14.27) (all, P less than 0.05). Multiple stepwise regression analysis identified the following parameters as risk factors of PHYS: depression (P less than 0.001), perception of being seriously ill (P less than 0.001), self-payment for treatment (P = 0.003), CHB significant impact on income (P = 0.002), poor appetite (P = 0.002), langur (P less than 0.001), and fear of infecting others (P = 0.022). Confidence of treatment was a protective factor of PHYS (P = 0.001). The risk factors of PSYCH were depression (P less than 0.001) and recurrence (P less than 0.001), and the protective factors were confidence of treatment (P = 0.003) and male sex (P = 0.014). The risk factors of SOCIL were depression (P less than 0.001, dissatisfaction with the attitude of the people around (P = 0.001), recurrence (P = 0.008), and advanced age (P = 0.009), and the protective factors were social support (P less than 0.001) and confidence of treatment (P = 0.015); however, the scores were significantly different for different occupations (P = 0.008). The risk factors of ENVIR were depression (P less than 0.001), dissatisfaction with the attitude of the people around (P less than 0.001), living in rural area (P = 0.007), and recurrence (P = 0.016).

CONCLUSIONPatients should be monitored for depressive symptoms during the course of clinical medical care for CHB so that psychological care may be initiated in a timely manner. It is important to strengthen communication between healthcare professionals and patients in order to improve the patient's perception of social support and quality of life.
