OBJECTIVE: To investigate the genetic polymorphisms of 19 STR Loci in Shandong Han population in order to provide the genetic data for paternity testing. METHODS: The genotypes of 205 unrelated individuals in Shandong Han population were typed by Goldeneye 20A kit to get the allele frequencies and population genetic parameters of 19 STR loci. Four kits, Identifiler kit, SinoFiler kit, PowerPlex 16 kit, and Goldeneye 20A kit, were compared with each other and used in the analysis of a special paternity test case. RESULTS: The population genetic parameters of 19 STR loci in Shandong Han Population were obtained. The cumulative discrimination power (CDP) and cumulative probability of exclusion (CPE) ranked from high to low were Goldeneye 20A kit, SinoFiler kit, PowerPlex 16 kit and Identifiler kit, respectively. As duo case, the result of the real case showed that Identifiler kit had no excluding loci, and none of the SinoFiler kit, PowerPlex 16 kit or Goldeneye 20A kit could exclude fatherhood. CONCLUSION Compared with Identifiler kit, SinoFiler kit, and PowerPlex 16 kit, Goldeneye 20A kit shows the higher efficiency than the others, but is not completely satisfied for duo cases.

0.05). Conclusion Preproghrelin-Leu72Met is not significantly associated with T2DM and DN in Shanghai Han populations,while T2DM with AA genotype is characterized by significant declination in urine microalbumin when compared with CA and CC genotypes.Leu72Met polymorphism(C→A)may postpone the development of microalbuminuria in T2DM subjects.

Objective To explore whether there are effects of oral antibiotics before skin anaphylaxis test to antibiotics on the results of skin test, and the related factors influencing the positive skin test in antibiotics, so as to provide evidences for health education for nurses' standard use of antibiotics. Methods 130 patients who had no allergic history of medications underwent antibiotic skin test. The correlation between results of skin test and whether taking antibiotics orally before skin test was observed. Results There was no statistical meaning between the positive rates of skin tests for cephalesporin antibiotics and penicillins antibiotics; the positive rate of patients who took antibiotics orally before the skin test was higher than that of patients who took no antibiotics; the positive rate of skin test had no correlation with the age and sex of patients as well as the drugs for skin test, but there was correlation with taking antibiotics before skin test. Conclusions When conducting the skin anaphylaxis test to antibiotics, nurses should strictly observe the patients who have no allergic history of medications but take antibiotics orally before skin test.

OBJECTIVETo observe the clinical manifestations of bullous retinal detachment and analyze the etiological factors.

METHODSA retrospective analysis of the clinical data was conducted in 22 patients with multifocal retinal pigment epitheliopathy (DRPE) and big bullous retinal detachment (BBRD), who were admitted between 2003 and 2008 in Zhongshan Ophthalmic Center with the diagnoses established by ocular fundus examination, fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA).

RESULTSThe patients included 15 men (68%) and 7 women (32%), with a mean age at the initial visit of 42 years, ranging from 25 to 64 years. Four patients (18%) received previously systemic corticosteroid therapy, and 2 of them used corticosteroids before retina detachment, 1 suffered progression of retinal detachment after corticosteroid therapy, and the other developed retinal detachment in the healthy eye during the therapy. Multifocal bullous retinal detachment was diagnosed as diffuse pigment epitheliopathy (DRPE) in 9 cases. Most of the 13 cases of big bullous retinal detachment had poor vision after operation and laser therapy.

CONCLUSIONBullous retinal detachment occurs most frequently in mid-life and more often in men than women. Abnormal retinal pigment epithelium (RPE) and hyperpermeability of the choroid vessels are associated with its occurrence. Systemic corticosteroid therapy and mental stress may induce and aggravate this disease. Early medication and laser therapy are effective, and surgical intervention may save only part of the vision in advanced cases.

OBJECTIVETo establish a human ovarian cancer-bearing mouse model via orthotopic transplantation of human HO-8910 cells expressing green fluorescent protein (GFP).

METHODSGFP-expressing human ovarian carcinoma HO8910/GFP cells (2 x 10(6)) in exponential phase of growth were inoculated subcutaneously in nude mice, and the generated tumor tissues were collected and transplanted below the capsule of the left ovary of 6 nude mice. The growth of the tumors was observed in vivo using a fluorescence stereomicroscope. The nude mice were sacrificed 4 weeks after transplantation to assess the tumor growth and metastasis.

RESULTSThe tumors showed progressive growth at the orthotopic sites in all animals. Two weeks after the transplantation, green fluorescent mass was observed at the left costovertebral angle, and the mass increased thereafter and invaded or metastasized to the peritoneum, omentum, spleen, liver, uterus, and the pelvic lymph nodes, with a metastatic rate as much as 66.7%.

CONCLUSIONThe nude mouse model bearing orthotopic human ovarian carcinoma expressing GFP has been successfully established.

AIMTo introduce the manufacture and use of a simple, new type of drop recorder of frog heart.

METHODSTo improve the perfusion device of (see text for symbol) and Straub method. Two electrodes of drop recorder were fixed in an injector of 20 ml. The input tube, output tube and resistance tube were all made of plastic material.

RESULTSThis device could be used to observe effects of preload, after-load, hormone and electrolyte on the cardiac output in isolated frog heart.

CONCLUSIONThe new type of drop recorder was economical and could be easily operated, it could be also connected to computer. Using the new type of drop recorder, effects of various physical and chemical factors on cardiac function could be observed directly, accurately.

BACKGROUND:The immunomodulatory ability of bone marrow mesenchymal stem cells(BMSCs)gives it a promising future in treating graft-versus-host disease(GVHD),especially with previous success in treating patients with acute GVHD.However,there are fewer reports concerning BMSCs in treating chronic GVHD,particularly for sclerodermatous chronic graft-versus-host disease(ScGVHD).OBJECTIVE:To evaluate the efficacy and safety of treatment of BMSCs for ScGVHD,and to primarily explore the immunological mechanism of clinical efficacy.METHODS:Four ScGVHD patients at the Affiliated Hospital of Academy of Military Medicine Science,between September 2006 and August 2008,were enrolled for this trial.The median patient age was 41 years,1 female and 3 male.The patients received BMSCs infusion at a dose of(1.0～2.0)×10~7 cells every time by intrabone marrow injection from the anterosuperior iliac spine and BMSCs from the same donor for the same patient were infused more than once.Concomitant medications for ScGVHD were individualized for each patient,but all were current standard medicines and the doses were significantly tapered.RESULTS AND CONCLUTION:After BMSCs infusion,the ratio of Th1 to Th2 was dramatically overturned,with an increase of Th1 and a decrease of Th2 reaching at a new balance.Correspondingly,symptoms of all the four patients gradually improved.During the course of BMSCs treatment,the life signs and laboratory results from the recipients remained normal.By the time of this report,there has been no recurrence of leukemia in the four patients.Although this study alone cannot guarantee the application of BMSCs in ScGVHD,the results are strongly in favor of the idea that the BMSCs treatment for ScGVHD patients is therapeutically practical without any detectable side effects,which may provide a new insight into the matter of treating ScGVHD clinically,thus will greatly increase the survival rate of leukemia after allogeneic bone marrow transplantation.
