Objective To investigate the expression of TLR9 mRNA of peripheral blood mononuclear cells (PBMCs) in patients with acute pancreatitis .Methods Fifty two AP patients with the disease duration in 24 h were collected ,peripheral EDTAK2 coag‐ulation vein blood were collected on the first ,third and fifth day ,then plasma were cryop reserved to detect pancreatic elastase , proinflammatory cytokines and anti‐inflammatory cytokines .Then the peripheral EDTAK2 coagulation vein blood two to three months after treatment were collected in the same method to undertake these tests ,and act as the reference level value .Peripheral blood was collected from 36 acute pancreatitis patients .Three months later ,peripheral blood was collected again from these 36 peo‐ple as controls .PBMCs were isolated by Ficoll‐Hypaque gradient centrifugation .RT‐PCR was adopted to determine the relative con‐tent of the expression of TLR9 mRNA of the PBMCs .Results The relative content of expression of TLR9 mRNA were significant‐ly up‐regulated in the patients with acute pancreatitis ,compared with that of controls (P<0 .05) .The up‐regulated expression of TLR9 mRNA was related to expression of TNF‐a and IL‐1 .Conclusion The up‐regulated expression of TLR9 mRNA in acute pan‐creatitis patients indicates that infective factors might be mediated by TLR 9 .

OBJECTIVETo find a method without corticosteroids, aspirin or heparin for treatment of anticardiolipin antibody-positive early recurrent spontaneous abortion (AARSA).

METHODSTwenty-three patients of AARSA in the treated group were treated with Chinese herbal medicine (CHM) plus human chorionic gonadotropin and progesterone, and 18 patiens in the control group were treated with multi-vitamin only. The change of anticardiolipin antibody was determined by enzyme linked immunoabsorbent assay (ELISA).

RESULTSAfter treatment, anticardiolipin antibody negative converted in 20 cases (86.9%) of the treated group. The cure rate of abortion in the treated group was 82.6% (19/23), which was raised to 95% (19/20) in those patients with antibody negative conversion, while in the control group, it was 16.7% (3/18) merely, comparison between the two groups in cure rate showed significant difference (P < 0.01).

CONCLUSIONCHM plus human chorionic gonadotropin and progesterone could cure AARSA effectively.

OBJECTIVETo investigate the feasibility and clinical application value of selecting viable spermatozoa by noncontact diode laser.

METHODSWe obtained immotile spermatozoa from 2 infertile men with obstructive azoospermia or severe asthenospermia and selected viable spermatozoa using a single laser shot at the sperm tail. Those that responded to the laser shot by a curling reaction of the tail were regarded as presumably viable and used for intracytoplasmic sperm injection (ICSI).

RESULTSThe mean fertilization rate was 88.89% after ICSI with the laser-selected viable spermatozoa. Both of the embryo transfers resulted in a single pregnancy.

CONCLUSIONNoncontact diode laser is a useful alternative for the assessment of sperm viability, which may help to achieve successful pregnancy.

PURPOSE: This study applied the Q method to identify and describe the various types of nurse perceptions that are crucially associated with their engagement in evidence-based nursing (EBN). METHODS: The study participants were nurses at a medical center and a regional teaching hospital. A series of Q sorts was performed by nurses to subjectively rank the Q statements. Q statements were constructed based on the literature related to EBN adoption by nurses and face-to-face interviews. RESULTS: A total of 60 participants were invited to rank 44 Q statements related to EBN. Factor analysis was conducted on the rankings of the Q statements. The following are the five prominent shared perspectives: (1) emphasized the obstacles to evidence searching and reading ability; (2) emphasized the organizational promotive strategies; (3) emphasized the available supportive resources; (4) emphasized the significance of EBN; and (5) emphasized the evidence-searching ability and external incentives. The five identified groups of perspectives can enhance hospital administrators to acknowledge the barriers and incentives associated with EBN practices. CONCLUSION: The exploration of clustering nurses' perceptions may facilitate the development of customized strategies to enable more appropriate training.

To investigate the effect of treadmill running on the ability of learning in young rats, male Sprague-Dawley rats (5 weeks of age) were used for the experiment. Animals were randomly divided into the control and running groups (n=15 in each group). The rats in running group were made run on a motor-driven treadmill for 1 week at a speed of 2 m/min for the first 5 min, at a speed of 5 m/min for the next 5 min, then at a speed of 8 m/min for the last 20 min. Then the Morris water maze was used to observe learning and memory ability of rats in both groups. The tests consisted of place navigation and spatial probe test. We found that, in place navigation training, the latency of rats in running group was less than that in control group (P<0.05); and from the third training session on, there was significant difference between the rats in control and running groups in swimming velocity (P<0.01); furthermore, it was observed that the rats in running group had stronger motivation and more exact orientation in searching for platform, which could be indicated by the index of turn angle and angular velocity. In spatial probe test, there was no significant difference between the two groups in swimming velocity, percentage of swimming distance and frequency of crossing platform in D quadrant, where the platform situated (P>0.05). These findings suggest that low speed treadmill running can enhance the ability of learning in young rats.

OBJECTIVEData accumulated over the past years have led to widespread recognition that neurogenesis, the emergence of new neurons, persists in the hippocampal dentate gyrus of the adult mammalian brain, and can be increased by seizures in multiple models. Also, aberrant reorganization of dentate granule cell axons, the mossy fiber sprouting, occurs in human temporal lobe epilepsy and rodent epilepsy models. However a number of studies suggest that the immature brain is less vulnerable to the morphologic alteration of hippocampus after seizures. The goal of this study was to determine whether the seizures can induce dentate granule cell neurogenesis and mossy fiber sprouting in the immature rat.

METHODSSeizures was elicited by unilateral microinfusion of kainic acid (KA, 1 micro g) into the amygdula at postnatal day 15 (P15). Rat pups were given bromodeoxyuridine (BrdU) intraperitoneally on day 5 after KA administration and killed 7 d or 21 d later. The brains were processed for BrdU mitotic labeling combined with double-label immunohistochemistry using neuron-specific, early differentiation marker TuJ1 (betaIII tubulin) or granule-specific marker CaBP (calcium-binding protein calbindin D28k) as well as glia-specific marker GFAP (glial fibrillary acidic protein). Mossy fiber sprouting in intermolecular layer and CA3 subfield was assessed in Timm-stained sections both 1 month and 3 months after KA administration by using a rating scale and density measurement.

RESULTSThe dentate BrdU-immunoreactive cells of the KA-treated rats increased significantly compared with those of control rats on day 7 and 21 after BrdU administration (7 d: 244 +/- 15 vs. 190 +/- 10; 21 d: 218 +/- 19 vs. 133 +/- 12, P < 0.05). Approximately 80.2% and 78.7% of BrdU-labeled cells coexpressed TuJ1 in KA-treated rats and control rats on day 7 after BrdU respectively (P > 0.05). On 21 d after BrdU, 60.2% and 58.2% of dentate BrdU-labeled cells coexpressed GaBP in KA-treated rats and control rats respectively (P > 0.05). GFAP colocalized with 3%-5% dentate BrdU-labeled cells in the rats of both groups on day 7 and 21 after BrdU. It was also demonstrated that status epilepticus at P15 did not result in any detectable mossy fiber sprouting within the hippocampus both 1 month and 3 months after KA administration.

CONCLUSIONSKA induced seizures can increase granule cell neurogenesis in the immature rat. Most of newly appeared cells migrate from subgranular proliferation zone (SGZ) into granule cell layer, the hilus as well as the molecular layer, and there they can differentiate into granule neurons. These observations also indicate that there is an early developmental resistance to seizure-induced mossy fiber sprouting in the immature brain.
