Tumor markers of breast cancer are closely related to its biological behaviors and are essential for treatment strategy making. Although traditional immunohistocbemistry(IHC) is the most commonly used molecular pathological method for tumor marker detection, it can not meet the clinical requirements for quantitative and individualized treatment. With the unique photo-physical properties of quantum dots(QDs), QDs conjugated probes have been successfully used in molecular and in vivo imaging, in the study on mechanism of drug delivery and targeted therapy and especially in the detection of tumor markers in vitro and molecular targeted diagnosis of breast cancer and individualized treatment strategy making. The technique has a broad prospect in clinical application.

BACKGROUND: Rheumatoid arthritis(RA) is an autoallergic disease,but its immunological pathogenesis has not been completely known. T lymphocytes, especially CD4+ TH1/TH2 cells, may have an important effect in the occurrence and development of RA.OBJECTIVE: To investigate the action of CD4+ TH1 and TH2 cells which separately mediate cellular immunity and humoral immunologic response (respectively) function in the occurrence and development of RA.DESIGN: Case-control, comparative observation.SETTING: Department of Immunology, Medical College of Chinese People's Armed Police Forces.PARTICIPANTS: Totally 15 patients with RA hospitalized in the Department of Internal Medicine of General Hospital of Tianjin Medical University between March 1999 and March 2000 were selected for a RA patient group, consisting of 2 males and 13 females. Of them, 12 patients whose serumal rheumatoid factor (RF)was positive and the three others' was negative. At the same time, 30 healthy individuals from persons receiving health examination in the hospital or from our department were selected for a healthy control group, consisting of 4 males and 26 females. Informed consents were obtained from the participants.peripheral blood mononuclear cells(PBMC) from the two groups of subjects were detected by enzyme-linked immunospot assay (ELISPOT). 200-500 lymphocytes were counted under a normal light microscope, and the perwhich secreted cytokines were detected by ELISPOT, and those which had red spots in their plasma after staining were positive cells. Among them,the cells secreting γ-interferon (IFN-γ) were Tm cells while those secreting interleukin-4 (IL-4) were TH2 cells. 200-500 lymphocytes were counted under a normal light microscope and the percentages of TH1 and TH2 cells square test were used for comparing statistical differences of data between the two groups.MAIN OUTCOME MEASURES: Quantitative analysis of T lymphocyte subsets (including CD3+ T cells, CD4+ T cells and CD8+ T cells) and CD4+ TH1/TH2 cells in peripheral blood from the two groups of subjects.RESULTS: Analysis of the results was from the study on all of subjects percentages of total T cells (CD3+ T cells), CD4+T cells and CD8+F cells in peripheral blood were not significantly different between the two significantly higher in RA patient group than that in healthy control group [(24.44±5.25)%, (14.93±3.82)%, P < 0.05],while in RA patient group the percentage of TH2 cells and ratio of TH1 cells to TH2 cells from peripheral blood were not significantly different as compared with those of control group(P > 0.05).CONCLUSION: Cellular immunologic function mediated by TH1 cells may be associated with the occurrence and development of RA.

Objective: To discuss the applied effect of high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention for stroke patients with aphasia. Methods: 84 stroke patients with aphasia were divided into observation group (42 cases)and control group (42 cases). Patients of control group were treated by routine intervention of language training, while patients of observation group were treated by high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention. A series of evaluated indicators, such as the language function score of Boston diagnostic aphasia examination(BDAE), the anxiety symptom score of Hamilton anxiety scale(HAMA), the quality of life and degree of satisfaction, were adopted to compare the post-treatment effect for the two groups. Results: After the treatment, there were statistical significance in the difference of understanding, retelling ability, reading ability and writing ability about BDAE scores between the two groups (t=3.572, t=4.482, t=6.238, t=3.013; P<0.05), and the HAMA scores of observation group was significant higher than those of control group (t=3.472, P<0.05). Besides, through different interventions, the series of indicators about quality of life, such as physical function, mental function, social function and material function, of observation group were higher than those of control group (t=4.513, t=3.923, t=4.473, t=4.033; P<0.05). And the satisfaction of observation group was significant higher than that of control group (x2=5.233, P<0.05). Conclusion: The clinical effect of high frequency repetitive transcranial magnetic stimulation combined with cognitive intervention for stroke patients with aphasia is favorable. And this method can increase quality of life and satisfaction for patients, and can extremely reduce medical dispute and improve the therapeutic level of hospital for stroke patients with aphasia.

Objective To analyze the pregnancy outcome of laparoscopic cervical cerclage before pregnancy, discuss the clinical value of the treatment of cervical incompetence.Methods 40 cases with cervical insufficiency during 2012.1 -2016.3 before pregnancy underwent laparoscopic ligation.All patients had a history of abortion or premature birth,and the average gestational age was 23.7 weeks.Preoperative cervical length was less than 2.5cm. The operation condition and the pregnancy outcome after operation were observed.Results The average time of oper-ation was 35.6(40.2 ±10.4)min and the amount of bleeding was 10.3(15.7 ±3.2)mL.Postoperative pregnancy cervical average length was 3.61 (4.35 ±0.52)cm.Pregnancy outcome:37 weeks of gestation and above delivery 20 cases (50.0%).34 -37 weeks 16 cases (40.0%),28 -34 weeks in 3 cases,received cesarean section,the aver-age gestational was 35.6 weeks.Compared with the preoperative abortion,the gestational week of delivery was pro-longed by 12.1 weeks.Neonatal survival in 38 cases (95.0%),1 case of gestational 28 +3 weeks premature death. Neonatal birth weight was 2 800(3 079 ±500)g;1 case (2.5%)was difficult to avoid abortion at 23 weeks of gesta-tion.Conclusion Laparoscopic pre -pregnancy cervical cerclage suture in cervix mouth,postoperative can maintain effective cervical length,prolong gestational age,improve the pregnancy outcome,can be used as effective treatment for the pregnant cerclage failure or cervical length less than 2.5cm of cervical insufficiency patients.

Objective To explore the role of type Ⅶ collagen (COL7A1) gene in the pathogenesis of pretibial dominant dystrophic epidermolysis bullosa (DDEB-Pt).Methods Peripheral blood samples were obtained from a sporadic Chinese patient of Han nationality with DDEB-Pt,his parents and 100 healthy human controls.A modified salting-out method was used to extract genomic DNA from the blood samples,and PCR was performed to amplify 118 exons of the COL7A1 gene followed by DNA sequencing.Results A G→A mutation was identified at position 6109 (G6109A) in exon 78 of the COL7A1 gene in this patient,which caused a change from GCT to ACT at codon 2037 in the triple helix region,and resulted in the substitution of glycine (Gly) by arginine (Arg) (p.Gly2037Arg).Conclusion A novel glycine substitution mutation was identified in the COL7A1 gene in the patient with DDEB-Pt,which may be a pathogenic mutation.

Objective To investigate the clinical and genetic characteristics of a progressive symmetric erythrokeratoderma (PSEK).Methods The clinical and genetic characteristics of a PSEK were compared and analyzed with clinical collection and review of 17 PSEK families reported in China since 1980.Results PSEK was consistent with autosomal dominant inheritance.PSEK had the feature with incomplete penetrance and variable expression.The clinical features included hyperkeratotic plaques with distinct border and strikingly symmetric distribution pattern on the extremities.Part of patients was extended to other areas of the body.The onset of the disease commonly started in infancy or childhood.The general health condition was not affected.PSEK might be associated with other clinical symptoms.The diseased potential increased in the family of consanguineous marriage.Conclusions PSEK has genetic heterogeneity.Its causative genes have not been determined.Further studies are needed.
