Objective To explore the influence of automatic and semi-automatic hemodialyzer reuse method on hemodialyzer reuse effect. Methods 1728 dialyzers were randomly divided into automatichemodialyzer reuse group and semi- automatic hemodialyzer reuse group with 864 dialyzers in each group. Thetime of douching and testing, the cost of sterilization,the frequency of the pyrphgen reaction,the broken dialyzer membrane and re-examined dialyzer between the two groups were measured. Results The time of douching dialyzer, testing of total cell volume and pressure in the semi- automatic hemodialyzer reuse group was (26.443±3.237), (2.172±0.128) and (2.157±0.090) minutes respectively,while the automatic hemodialyzer reuse group was (5.793±0.193), (1.257±0.118) and (1.110±0.076) minutes respectively. The frequency of re-examined dialyzer in testing total cell volume and pressure was 499(57.755%), 243(28.125%) respectively. At the same time, all dialyzer in semi-automatic hemodialyzer reuse group could be examined successfully at a time. The cost of sterilization in automatic henmdialyzer reuse group was (9.330±0.138)yuan. No pyrogen reaction and broken dialyzer membrane happened. Conclusions The semi-automatic bemodialyzer reuse group can retrench cost during perfusion,but consumes long douching time, lacks matching detection equipment, difficult to detect, and is not easy to read data and has high re- examination rate. while in the automatic hemodialyzer group, it is convenient of douching and detection, but the cost of sterilization and equipment is high, and clinical demand can be fulfilled only when the dialysis center can allocate reasonable number of the machines.

OBJECTIVETo evaluate its mechanism of inducing the maternal-fetal immune tolerance by studying the effects of Shoutai pills on the expression of Th1/Th2 cytokine and pregnancy in maternal-fetal interface of mice with recurrent spontaneous abortion (RSA).

METHODThe normal pregnancy and RSA model were respectively induced with CBA/J x BALB/c and CBA/J x DBA/2. The mice with RSA were randomly divided into model group and low, middle and high dose groups of Shoutai pills. The mice were killed in 14 days after administration and embryo resorption rate was counted and their decidual and placental tissues were co-cultured to detect the expressions of IL-4, IL-10, IFN-gamma and TNF-alpha with ELISA.

RESULTThe embryo resorption rate of the model group was significantly higher than the normal pregnancy, middle and high dose groups of Shoutai pills could decreased the embryo resorption rate of the mice with RSA (P < 0.05). All the doses in 3 groups of Shoutai pills could decreased the expression of IFN-gamma and TNF-alpha (P < 0. 05) and there was no obvious difference between normal pregnancy group and all groups of Shoutai pills. Middle and high doses of Shoutai pills could increased the expression of IL-4 and IL-10 (P < 0.05) and there was no obvious differences between normal pregnancy and high dose group of Shoutai pills.

CONCLUSIONThe mechanism about Shoutai pills can change Th1 /Th2 cytokine towards Th2 bias, which induced the maternal-fetal immune tolerance.

Conclusions A stable and highly intelligent computer-aided-controlling and image analysis system for light/dark box test of mice and rats has been developed,and it could be used for pathological mechanism studies of anxiolytics.

Objective: To investigate human enterovirus (HEV) infection and clinical characteristics of viral encephalitis patients in Pingdingshan, Henan Province. Methods: Cerebrospinal fluid specimens and epidemiological information were collected from 274 viral encephalitis patients in the departments of pediatrics and neurology in hospitals in Pingdingshan, Henan Province, from April 2011 to August 2012. Patients with bacterial infections were excluded from the study. Demographic information was collected by questionnaires and clinical information was mainly obtained from hospital examinations. Viral RNA was extracted using magnetic bead extraction. Real-time RT-PCR was then performed for HEV, CV-A16, and EV-A71 testing. SPSS statistical software was statistical analyses. Significant differences were determined using the chi-squared test (P<0.05). Results: Among 274 cases of viral encephalitis, 180 cases (65.7%) were male and 94 cases were female (34.3%). The median age was 2.17 years. Approximately 61.3% (168) of patients were younger than 3 years of age. A total of 107 (39.1%), 2 (0.7%), and 42 (15.3%) cases were positive for HEV, CV-A16, and EV-A71, respectively. Eleven patients were younger than 6 months of age and one patient was co-infected with HEV and EV-A71. In the<3, 3-5, 6-15, and>15 years old age groups, HEV infections comprised 31.5% (53/168), 52.9% (18/34), 53.0% (35/66), and 16.7% (1/6) (χ²=13.10, P=0.003), respectively. The EV-A71 infection rates were 17.9% (30/168), 23.5% (8/34), 6.1% (4/66), and 0 (χ²=8.04, P=0.045), respectively. The other enterovirus (OEV) infection rates were 12.5% (21/168), 29.4% (10/34), 48.5% (32/66), and 16.7% (1/6) (χ²=35.19, P<0.001), respectively. The rate of vomiting in OEV and EV-A71 infected patients was 73% (44/60) and 26% (11/42), respectively, while the frequency of skin rash in OEV and EV-A71 infected patients was 32% (19/60) and 79% (33/42), respectively. Approximately 95% (99/104) of patients infected with HEV had a fever, and the breathing rhythm change rate was 19% (20/104), which was lower than that of patients without HEV infection (36.8% (60/163)) (χ²=9.35, P=0.002). Conclusion In Pingdingshan, HEV was a major causative agent of viral encephalitis and the rate of OEV infection was high, especially in children aged 3-15 years old. Fever was a common clinical symptom of patients infected with HEV. Patients infected with OEV primarily exhibited vomiting symptoms and EV-A71 infected patients showed skin rash.
