2.Study Progress on Embryonic Stem Cells and Adult Stem Cells Derivated into Male Germ Cells
Journal of Applied Clinical Pediatrics 2004;0(08):-
Embryonic stem cells(ESCs),a kind of totipotent cells,can differentiate into cell type of the 3 germ layers.Adult stem cells(ASCs) are pluripotent stem cells,which can self-renew and transdifferentiate into a completely different tissue derivative cells.Thus ASCs can transdifferentiate into germ cells in a certain condition.Great progress has made for the study on human ESCs.However,use of ESCs faces the immunological rejection,oncogenicity and ethical controversies problems,and these limit their uses for treatment of human diseases.On contrast,ASCs can advoid these problems,and they may have a better perspective.Germ cells as carriers of genetic materials,are worth of studying.If male germ cells can be derived from ASCs,this will open the possibilities for the use of these cells for male infertillty in clinical application.In this review,we will introduce the progress on derivation of male germ cells from ESCs and ASCs.

Celastrol is a type of quinone methyl triterpene isolated from traditional Chinese medicine Tripterygium wilfordii, with pharmacological activities, like anti-inflammatory, immunosuppression and anti-tumor. This study focused on the effects of celastrol on adhesion, migration and invasion of lung cancer cells. The migration inhibition of lung cancer cells induced by celastrol was detected by the scratch test. The invasion inhibition of lung cancer cells induced by celastrol was measured by the transwell experiment. RT-PCR and Western blot were used to determine the effect of different concentrations of celastrol in integrin family and Akt signaling pathway in lung cancer cells. The results showed that celastrol inhibited adhesion, migration and invasion of lung cancer cells and expressions of integrins β3, β4, αv and phosphorylated Akt, GSK-3β, c-Raf, PDK1 in Akt signal pathway in a dose-dependent manner. Therefore, the study implies that Celastrol could inhibit the metastasis of lung cancer cells by suppressing Akt signaling pathway and expression of integrins.

The painless needle insertion technique, summarized by Professor WU Lian-zhong during his decades of acupuncture clinical practice is introduced in this article, which is characterized as soft, flexible, fast, plucking and activating antipathogenic qi. The Sancai (three layers) lifting and thrusting manipulation technique is adopted by Professor WU for getting the qi sensation. And features of 10 kinds of needling sensation such as soreness, numbness, heaviness, distension, pain, cold, hot, radiation, jumping and contracture are summarized. Finger force, amplitude, speed and time length are also taken as the basis of reinforcing and reducing manipulations. Moreover, examples are also given to explain the needling technique on some specific points which further embodies Professor WU's unique experiences and understandings on acupuncture.

7.Development of a software for 3D virtual phantom design.
Journal of Biomedical Engineering 2014;31(1):76-80
In this paper, we present a 3D virtual phantom design software, which was developed based on object-oriented programming methodology and dedicated to medical physics research. This software was named Magical Phan tom (MPhantom), which is composed of 3D visual builder module and virtual CT scanner. The users can conveniently construct any complex 3D phantom, and then export the phantom as DICOM 3.0 CT images. MPhantom is a user-friendly and powerful software for 3D phantom configuration, and has passed the real scene's application test. MPhantom will accelerate the Monte Carlo simulation for dose calculation in radiation therapy and X ray imaging reconstruction algorithm research.

ObjectiveTo study the possibility of differentiation of human umbilical cord mesenchymal stem cells(HUCMSCs) into human male germ cells,and to explore a new source of cells for the treatement of male infertility.MethodsHUCMSCs were transplanted into the seminiferous tubules of the testis of infertile mice by microinjection.The survival rate,migration and germ cell markers of HUCMSCs in the mice testis were detected via immunohistochemistry,immunofluorescence and confocal laser scanning. ResultsHUCMSCs can survive in the mice testis for at least 120 days,and they can migrate from the lumens to the basement membrane.Immunofluorescence showed that HUCMSCs can further differentiate in the mice testicular environment,and express the germ cell marker.ConclusionsHUCMSCs can survive,migrate and differentiate into early male germ cell-like cells in the infertility mice testis after transplantation.

Objective To Study on regularity of iron deficient anemia(IDA) in gravida, provide preventive methods and improve hygienic quality.Methods IDA incidence rate of 12W~19W, 20W~27W, 28W~35W, 36W~pregnant duration were anlyzed in 521 gravida.Results The incidence of IDA in gravida was 16 87% and increased with the development of pregnancy.After 20 weeks of pregnancy,the incidence of IDA markedly increased accompanied with by the decreased Fe, SF and TS, especially during the 28~35 weeks of pregnancy, which reached the peak with the anenia incidence of 26 37%,and 80 50% of cases was irom deficient symptom,it suggesting iron deficiency in this stage and Fe, SF, TS decreased to the lowest level and the stored iron was almost exhausted and ZPP increased.Conclusions After 12 weeks of pregnancy,gravida should be supplemented with iron agent. It's also suggested that those gravida with gestational age older than 28 weeks with the Hb levels of less than 105g/L should be considered as IDA and should be treated with iron supplement. [
