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 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 .

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.

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.

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.

OBJECTIVETo review the recent developments in the mechanisms of epithelium sodium channels (ENaCs) induced bone formation and regulation.

DATA SOURCESStudies written in English or Chinese were searched using Medline, PubMed and the index of Chinese-language literature with time restriction from 2005 to 2014. Keywords included ENaC, bone, bone formation, osteonecrosis, estrogen, and osteoporosis. Data from published articles about the structure of ENaC, mechanism of ENaC in bone formation in recent domestic and foreign literature were selected.

STUDY SELECTIONAbstract and full text of all studies were required to obtain. Studies those were not accessible and those did not focus on the keywords were excluded.

RESULTSENaCs are tripolymer ion channels which are assembled from homologous α, β, and γ subunits. Crystal structure of ENaCs suggests that ENaC has a central ion-channel located in the central symmetry axis of the three subunits. ENaCs are protease sensitive channels whose iron-channel activity is regulated by the proteolytic reaction. Channel opening probability of ENaCs is regulated by proteinases, mechanical force, and shear stress. Several molecules are involved in regulation of ENaCs in bone formation, including nitride oxide synthases, voltage-sensitive calcium channels, and cyclooxygenase-2.

CONCLUSIONThe pathway of ENaC involved in shear stress has an effect on stimulating osteoblasts even bone formation by estrogen interference.
