Objective To analyze the clinical relationship of progesterone(P) and estradiol(E2) for embryo arrest in early pregnant patients.Methods 118 patients with embryo arrest in early pregnancy were selected and divided into two groups,research group (58 cases,embryo arrest in early pregnancy) and control group (60 cases,threatened abortion but embryo keeping growth by tocolysis).Serum P and E2 were measured and compared between two groups.Receiver operating characteristic curves(ROC) of all indexes were drawn and the areas under the ROC curves were calculated to evaluate diagnostic value.Results Compared to control group,the serum P and E2 were lower in research group(P ＜ 0.05).To diagnosis embryo arrest,the threshold for P was less than 118.4nmol/L,with 93.9％ sensitivity and 87.3％ specificity; while the threshold value for E2 was less than 1110pmol/L,with 95.6％ sensitivity and 90.7％ specificity.Conclusion Detection of serum P and E2 may be helpful for the diagnosis of embryo arrest in early pregnancy,and the serum E2 had the best diagnostic value.

We have known that neglect can often be multisensory.This paper reviewed auditory disturbances accompanied by visual neglect.Patients with visual neglect often show deficits in localisation of contralesional single sounds,particularly in the presence of an ipsilesional competitor.Auditory and visual aspects of neglect often correlate in their severity.Recent neuroimaging findings in the normal brain showed that the brain regions damaged in neglect patients might contain multimodal representations of space.

Genetic researches have been paid more attention in dentistry area recent years;however,researches mainly focus on the tooth specific genetic diseases.In this review,we review the detailed genetic syndromes which are related with abnormal enamel and dentin.We wish this review will be helpful to those who are interested in oral genetic research.

Objective To explore the clinicopathologic features,histological classification,prognosis and diag- nosis of ganglioneuroblasroma (GNB).Methods Histopathologic appearance,immunohistiehemical stainings were observed and analyzed in three cases of GNB.The associated literature were reviewed.Results The characteristics of GNB was detected that there was gangliocytes in component of differentiated neuroblastic tumour ceils.Immunohisti- chemical staining showed the tumor cells were positive for NF,NSE and CgA,and negative for S-100 protein,LCA, CD99 and Syn.Conclusions GNB is an uncommon tumour with poor outcome which composed of gangliocytes and neuroblastoma.To make a histological classification according to age,the ratio of neuroblastic tumour component and the differation of GNB will be very useful in clinical therapy and prognostic evaluation.

OBJECTIVE:To study the correlation between the usage and dosage of inhalations and the adverse drug reactions and the effect of pharmacetical care. METHODS:Aimed at the usage and dosage of inhalations,intervention was adopted in drug use of patients. RESULTS:The occurrence of the adverse drug reactions of inhalations was associated with patients' poor knowledge about correct usage of drugs. CONCLUSION:Clinical pharmacists' intervention on patients' use of inhalations achieves satisfactory outcome.

OBJECTIVE: To compare content of anthraquinones in the decoction and maceration of Rheum officinale.METHODS: Aloe emodin and four other components in R.officinale were taken as analysis objects.HPLC was used to determine the content of nomadic anthraquinone,conjugated anthraquinone and total anthraquinone in R.officinale during decoction process and maceration process.RESULTS: The linear range of aloe emodin,rhein,emodin and chrysophanol were 0.03～0.64?g and the linear range of physcion were 0.01～0.34 ?g.The concentration of total anthraquinones in decoction process was much higher than in maceration process.The change of dissolution of nomadic anthraquinones in two processes kept stable with process time.The content of conjugated anthraquinones in two processes was all decreased to some extent.CONCLUSION: The concentrations of anthraquinones in R.officinale are influenced by decoction process and maceration process.

OBJECTIVE: To observe the therapeutic effect of fallopian incubation recanalization (FIR) and Sargentodoxa cuneata decoction coloclysis in the treatment of tubal obstruction infertility. METHODS: 180 patients with tubal obstruction infertility were randomly divided into therapy group and control group (n=90). Therapy group were given S. cuneata decoction after FTR via self-made semi-Y-shaped catheter; control group were given FTR only. RESULTS: Two years after operation, the total effective rate of therapy group was 83.3%. In control group,the total effective rate was 60.0%. There was a significant difference between two groups (P

The oocyte cryopreservation is more promising than embryo freezing in clinical applications,preservation of female fertility,legal and ethical aspects in this decade.The redundant oocytes retrievedfrom ⅣF cycles can potentially donate oocytes,which have unique advantages in economy and feasibili-ty.We have achieved success in embryo freezing,but just obtained poorer results in oocyte cryopreserva-tion which was mainly because of the low rates of survival,fertilization,and cleavage.The character ofthe plasma membrane and the time of cortical granules present at the metaphase of meiosis Ⅱ with thespindle system consist of the major difference between oocytes and embryos.Moreover,the oocytes shouldbe fertilized by sperm at the appropriate time.We used a refined slow freezing method to improve the sur-vival rate and increased sucrose concentration to dehydrate oocytes.Vitrification was another approach toprevent harms.Besides,intracytoplasmic sperm injection was used to overcome possible zona hardeningafter the release of cortical granules.Oocytes after cryopreservation showed serious disturbances of the mi-crotubules immediately after thawing as they were vulnerable to the thermal changes and easy to depoly-merize.Fertilization of these oocytes with disorganized spindles led to chromosomal aneuploidy,digyny,and degradation of the cleavage rate.We can improve cryopreserved oocytes to normal fertilization anddevelopment by appropriate incubation and timing of insemination,as the microtubules repolymerize in atime dependent way after incubation which is compatible with recovery of the spindles.With the improve-ment of survival,fertilization,and development,oocyte cryopreservation will play an imperative role.

OBJECTIVE:To optimize the extract technology for Plumula Nelumbinis.METHODS:Four methods:water extraction(WE),water extraction by precipitation with alcohol(WAE),semi-bionic extraction(SBE),and semi-bionic ex-traction by precipitation with alcohol(SBAE)were used to extract Plumula Nelumbinis and also compared in their effects by adopting the total content of alkaloid and the yield of dry extract as markers.The comprehensive values Y was calculated.RESULTS:Through the comprehensive evaluation of the two markers,the comprehensive values Y ranked in the order of SBE,WE,SBAE and WAE.CONCLUSION:SBE method is the optimal method to extract Plumula Nelumbinis.
