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.

Objective To improve the recognition of nervous system symptoms of inborn errors.Methods Five patients with organic acidemias were screened by urine organic acid analysis(gas chromotography-mass spectrometry,GC/MS),3 cases of methylmalolic acidemias(MMA) and 2 cases of propionic acidemias(PA) were confirmed.They were treated with special diet and medicine after diagnosis.Result The improvement of mental development was observed after treatment.Conclusions Most of organic acidemias involve nervous systems,causing non-specific symptoms of nervous system as lethergy,seizures,mental retardation.Inborn errors of metabolism shall be kept in mind when causes of the symtoms of acidosis,seisures,mental retardation and lethergy are investigated.GC/MS is a very important method in diagnosis of organic acidemias.Early diagnosis and early treatment can improve the mental prognosis.

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.

OBJECTIVETo investigate the levels and roles of serum growth hormone (GH) and prolactin (PRL) in neonatal hypoxic-ischemic encephalopathy (HIE).

METHODSSerum GH and PRL levels were measured by radioimmunoassay in 54 neonates with HIE (20 mild, 19 moderate and 15 severe HIE) at the acute and convalescence stages. Twenty normal neonates were used as controls.

RESULTSSerum GH levels were significantly lower, but PRL levels were significantly higher in moderate and severe HIE neonates at the acute stage compared with those of controls and mild HIE neonates (P < 0.01). There were noticeable differences in serum levels of GH and PRL between the moderate and severe HIE cases (P < 0.01). During the convalescence stage, serum GH levels increased and PRL levels decreased in moderate and severe HIE neonates compared with those at the acute stage (P < 0.01); serum GH and PRL levels in each sub-group of HIE restored to the levels of controls. There was a closely negative correlation between GH and PRL levels at the acute stage of HIE (r = -0.8759, P < 0.01).

CONCLUSIONSGH and PRL might be involved in the pathophysiological process of HIE. The levels of GH and PRL closely relate to the severity of HIE at the acute stage.

OBJECTIVETo explore the effects of different fertilization methods on the outcomes of elective blastocyst culture.

METHODSWe retrospectively analyzed the outcomes of elective blastocyst culture for 1 153 cycles of IVF and 205 cycles of ICSI performed between january 2009 and December 2012.

RESULTSA total number of 14 748 embryos in the IVF group and 2 655 embryos in the ICSI group underwent sequential blastocyst culture, with 7 871 blastocysts formed in the former and 1 210 in the latter. No cycles were canceled for no blastocyst formation in either of the two groups. The rates of quality embryos, blastocyst formation and embryo utilization were significantly higher in the IVF than in the ICSI group (64.77 vs 58.72%, 53.37 vs 45.57%, and 60.06 vs 52.17%, all P < 0.05), but the rates of implantation, clinical pregnancy and abortion showed no significant differences between the two groups (48.94 vs 51.43%, 49.03 vs 52.02%, and 11.69% vs 15.56, all P > 0.05).

CONCLUSIONWith the same inclusion criteria of selective blastocyst culture, IVF has a lower risk of cycle cancellation due to no blastocyst formation and therefore may effect higher rates of blastocyst formation and embryo utilization than ICSI. Our study suggested that appropriate inclusion criteria of selective blastocyst culture should be laid down according to different fertilization methods.

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.
