Objective To explore the clinical value of preparatory treatment using estradiol valerate and mifepristone before the curettage of the late small missed abortion.Methods One hundred and twenty patients with late small missed abortion were randomly divided into two groups:pretreated group(n =660) and control group(n =60).Women in the pretreated group were given 5 mg of Estradiol Valerate 3 times/day and 25 mg of Mifepristone twice/day for 3 days each before conducted curettage on the fourth day.While for the control group,curettage was done directly.The condition of operation and the occurrence of short-and long-term complications were compared between the two groups.Results Compared with the control group,the pretreated group had a significant shorter operation duration[(8.6±2.7) rnin vs.(10.5±3.4) min,t =3.390,P =0.001]and less blood lose during operation[(47.5±18.3) ml vs.(61.8±20.5) ml,t =4.031,P ＜ 0.001].In terms of complications,the rates of incomplete curettage[(0 vs 13.3％,x2 =6.563,P =0.010],artificial abortion syndrome(3.3 ％ vs 15.0％,x2 =4.904,P =0.027),the cervical canal adhesion/Asherman' s syndrome(0 vs 11.7％,x2 =5.461,P =0.019),and the vaginal bleeding duration[(7.5±2.7) days vs(8.7±3.4) days,t =2.141,P =0.034]in the pretreated group were significantly lower than those in the control group.The average recovery time of menstruation after operation in the pretreated patients was significantly shorter than that in the control group[(30.5±9.3) days vs.(35.5±7.4) days,t =3.259,P =0.002].Contusion Estradiol valerate and Mifepristone as a preparatory treatment before the operation can help reduce the occurrence of complications and side effects in the late small missed abortion curettage and is helpful for the patients' recovery,thus worth wide clinical application.

Objective To obtain the protein interacting with inhibitor of differentiation1′(Id1′). Methods The recombinant bait plasmid pHybLex/Zeo Id1′ was constructed and transformed into yeast strain EGY48/ pSH18 34 to test pHybLex/Zeo Id1′ for non specific activation. Adult human lung cDNA libraries were screened to obtain true positive library plasmid. The true positive library clone was obtained by sequencing and basic local alignment sequence tool (BLAST). Results The recombinant bait vector, named as pHybLex/Zeo Id1′, was confirmed by sequencing. pHybLex/Zeo Id1′ was transformed into yeast strain EGY48/pSH18 34 and the transformants had no autonomously activated reporter genes. One true positive clone, obtained by screening of the adult human lung cDNA libraries, was confirmed to be Fyn by sequencing and BLAST. Conclusion Id1′ can interact with Fyn.

Coronary heart disease (CHD) is a common kind of cardiovascular disease which does serious harm to human health. It has become the first cause of people's death in many countries and regions. This article analyzed CHD-related animal experiments in recent ten years. It made a review on progress in the establishment of chronic and acute animal models of CHD from the animal selection and model establishment. It can provide guidance for the further research of CHD.

Anatomic hepatic resection not only enables enough tumor-free resection margin,but also guarantee the maximal remnant of normal liver tissue.A 61-year-old male patient with hepatic cancer was admitted to the Affiliated Hospital of Hainan Medical College in February 2012.Multiple space-occupying lesions were found in segment Ⅵ,Ⅶ and Ⅷ by computed tomography (CT).The results of CT volumetry analysis showed that the left hemihepatic volume was lesser than the minimal limit of survival,so anatomic hepatic segmentectomy of Ⅵ,Ⅶ and Ⅷ with preservation of segment Ⅴ was designed to guarantee the maximal remaining of normal liver tissue.Glisson's pedicle transection was used twice to divide the right hemihepatic Glisson's pedicle,segment Ⅵ and Ⅶ Glisson's pedicle,respectivley,then the resection line was determined,and anatomical hepatic segmentectomy of Ⅵ,Ⅶ and Ⅷ was completed.With the procedures adopted,the hepatic ischemia reperfusion injury and hemodynamic instability were maximally reduced during operation.

Objective To analyse effects of the serum levels of thyroid peroxidase antibodies (TPOAb) on antithyroid drugs (ATD) treatment in patients with incipient Graves disease (GD). Methods A total of 121 patients with incipient GD, who were used anti thyroid drugs for 12 months, were included in this study. Patients were dvided into two groups:TPOAb negative group (TPOAb≤35 IU/mL, n=49) and TPOAb positive group (TPOAb>35 IU/mL, n=72). According to the degree of TPOAb drops the TPOAb positive group was sub-divided into low level positive group (35 IU/mL1 000 IU/mL, n=20). The ATD total dosage for 12 months and thyroid-stimulating hormone (TSH), which returned to normal rate after treatment of 3, 6 and 12 months, were compared between groups. Results ATD total dose was lower in TPOAb positive group (1 743.82±265.38) mg than that of negative group (1 889.18 ±125.51) mg. The ATD total dosages were (1 759.71±230.29) mg, (1 793.75±299.02) mg, (1 731.54± 236.44) mg and (1 710.00 ± 290.73) mg for low level TPOAb positive group, medium level TPOAb positive group, high level TPOAb positive group, and very high level TPOAb positive group respectively. The recovering ratio of TSH was significantly higher in TPOAb positive group than that of TPOAb negative group after 3-month treatment (P<0.05). Conclusion TPOAb positive serum can lead to shorten the course of ATD treatment and reduce the total amount of ATD treatment in GD patients.

Objective To investigate the expression of FTO in gastric cancer tissues and the functional significance of FTO in MGC-803 cell line.Methods The FTO mRNA was detected by RT-qPCR in 54 cases of gastric cancer samples and their paired adjacent normal control tissues.The effect of FTO overexpression in MGC-803 on cell proliferation,cell migration and invasion were detected by CCK-8,wound heal and ranswell assays,respectively.Results The expression of FTO mRNA was significantly lower than that of adjacent tissues(P＜O.05).Furthermore,overexpression of FTO in MGC-803 cells inhibited cell proliferation,cell migration and invasion.Conclusions FTO is low expressed in gastric cancer tissues and inhibits gastric cancer cell line MGC-803 proliferation,migration and invasion.FTO is closely associated with the development of gastric cancer.

Objective　To study the protocol that induces adult rat bone marrow stromal cells (MSCs) to express neuron-specific enolase (NSE) in vitro. Methods　MSCs were preinduced with β-mercaptoethanol for 24 h, and then induced for 5 h. The positive percentages of NSE protein expression were measured by immunocytochemistry SABC staining. Results　After the induction, MSCs displayed neuronal morphologies, such as pyramidal cell bodies and processes which formed extensive networks. The positive percentage of NSE protein expression was (63.7±4.5)%. Conclusions　β-mercaptoethanol may induce adult rat MSCs to NSE-positive cells in vitro.
