Objective To study the fecel-oral and blood transfusion of TT virus. Methods Paired feces and serum samples from 6 patients with type B and/or C hepatitis were tested for TTV DNA and its titers by PCR with seminested primers.Genotypes were determined after their sequences were compared with the original N22 and TA278 clone.Results TTV DNA was detected in sera from all patients,while it was detected in feces from 3 patients,including 2 with high viral titers in serum.The detection of fecal TTV DNA was dependent on the viral titers in serum.TTV isolates in 3 pairs of feces and serum had identical sequence of 222 base pairs.Their genotypes were 1a,1b and 2,respectively.Conclusion The excretion of TTV into feces indicates that TTV would be transmitted not only parenterally but also nonparenterally by a fecal-oral route.

AIM: To investigate the effects of PAR-2 agonist peptide on the proliferation and cytosolic calcium concentration ([Ca~(2+)]_c) in human hepatoma cells HepG2. METHODS: Human hepatoma cell line HepG2 was cultured. The cells were treated with PAR-2 agonist peptide SLIGKV-NH_2 and the reverse PAR-2 agonist peptide VKGILS-NH_2, respectively. The [Ca~(2+)]_c of hepatoma cells were measured by microfluorimetric techniques based on calcium indicator fura-2/AM. The influences on proliferation of hepatoma cells were determined by MTT method. The changes of cell cycle were evaluated by flow cytometry, and the changes of cyclin D1 mRNA expression were detected by RT-PCR. RESULTS: After treated with 50 μmol/L SLIGKV-NH_2, a rapid rise of [Ca~(2+)]_c in HepG2 cells was induced (P<0.01), percent S phase, G_2/M phase and proliferation index (PI) of HepG2 cells were elevated (P<0.01), and cyclin D1 mRNA expression was significantly upregulated (P<0.01). The proliferation rates of HepG2 cells treated with 1-50 μmol/L SLIGKV-NH_2 were significantly increased, and the effect was in a dose-dependent manner (P<0.01 or P<0.05). No statistical significance of the difference between VKGILS-NH_2 and control group was observed (P>0.05). CONCLUSION: PAR-2 agonist peptide induces the rise of [Ca~(2+)]_c in HepG2 cells, upregulates the expression of cyclin D1 mRNA, accelerates the progress of cell cycle, promotes the synthesis of DNA and the proliferation of hepatoma cells via activating PAR-2 in vitro.

OBJECTIVETo study the incidence and characteristics of coagulation factor VIII (FVIII) inhibitor development in Chinese patients with hemophilia A.
METHODSA 24-month continuous follow-up was conducted among 215 Chinese patients with hemophilia A to observe the characteristics of FVIII inhibitor development and the clinical characteristics of the patients.
RESULTSThe cumulative incidence of FVIII inhibitor development in 24 months was 11.6% (25/215) in these patients. Of the 25 patients with FVIII inhibitor development, 18 (72%) had low-titer inhibitors and 7 (28%) had high-titer inhibitors. The patients developed the inhibitors after a median of 150 exposure days at a median age of 25 years (6-59 years). Fifteen patients with low-titer inhibitors (median 1.25 BU/ml) showed gradual disappearance of the inhibitors in a median of 10 months (6-15 months) without any treatment, and 5 patients with high-titer inhibitors (median 100 BU/ml) remained positive in 24 months; the other 5 FVIII inhibitor-positive cases showed no significant changes. In the 25 patients developing FVIII inhibitors, the bleeding frequency increased significantly (P=0.025), and in 18 of the patients who continued to use FVIII products, a significant increase in the dose of medication was noted (P=0.015), but the number of target joints did not increase in 24 months (P=0.329).
CONCLUSIONThe incidence and characteristics of factor VIII inhibitor development differ between Chinese patients with hemophilia A and those in developed countries.

OBJECTIVEThe human socio-economic development depends on the planet's natural capital. Humans have had a considerable impact on the earth, such as resources depression and environment deterioration. The objective of this study was to assess the impact of socio-economic development on the ecological environment of Wuhan, Hubei Province, China, during the general planning period 2006-2020.
METHODSSupport vector machine (SVM) model was constructed to simulate the process of eco-economic system of Wuhan. Socio-economic factors of urban total ecological footprint (TEF) were selected by partial least squares (PLS) and leave-one-out cross validation (LOOCV). Historical data of socio-economic factors as inputs, and corresponding historical data of TEF as target outputs, were presented to identify and validate the SVM model. When predicted input data after 2005 were presented to trained model as generalization sets, TEFs of 2005, 2006,..., till 2020 were simulated as output in succession.
RESULTSUp to 2020, the district would have suffered an accumulative TEF of 28.374 million gha, which was over 1.5 times that of 2004 and nearly 3 times that of 1988. The per capita EF would be up to 3.019 gha in 2020.
CONCLUSIONSThe simulation indicated that although the increase rate of GDP would be restricted in a lower level during the general planning period, urban ecological environment burden could not respond to the socio-economic circumstances promptly. SVM provides tools for dynamic assessment of regional eco-environment. However, there still exist limitations and disadvantages in the model. We believe that the next logical step in deriving better dynamic models of ecosystem is to integrate SVM and other algorithms or technologies.

Objective To explore the current status of the prenatal care quality and the influencing factors in Hangzhou City. Methods We used sociodemographic characteristics questionnaire and the Chinese version of QPCQ to investigate 383 pregnancy women who were at 36 weeks' gestation or greater by convenient sampling method from September to December in 2016. Results A total of 350 questionnaires were valid. The average age of 350 samples was (29.71±3.67) years old. There were 231 primiparas which accounted for 66.00%. Among them, 196 (56.00%) were satisfied with the prenatal care they received, and 153 (43.70%) think general, and only 1 (0.30%) felt unsatisfied. The score of the Chinese version of QPCQ was 3.61±0.50. The item "My prenatal care professional (s) always answered my questions honestly" had the highest scores of 4.10±0.62, while "My prenatal care professional (s) did things hastily" had the lowest scores of 2.44±0.96 . By multiple linear regression analysis, those people who had more visiting time (β' = 0.21, P<0.01), less waiting time (β' = -0.18, P<0.01) and the cognition of the essentiality of pregnancy school (β' = 0.12, P=0.02) were more likely to give higher regards for the quality of prenatal care. Conclusion Sufficient time scored relative lower in the whole questionnaire. So, hospitals could take efforts to shorten the waiting time by promoting the hospital process optimization, making good use of this period time and other strategies, so as to improve the quality of prenatal care.
