Hematopoietic stem cell transplantation (HSCT) is the only effective curative therapy for patients with certain hematological diseases. Haploidentical HSCT has been practiced worldwide for approximately twenty years. Significant improvements on this therapy were made in China within the past decade, with the novel non-in-vitro, T-cell-depleted haploidentical HSCT system. This review de-scribes the current situation and provides a prospective overview of these novel HSCT systems in China.

Relations between doctor and patient are basic and important human relation in medical practice.Because of some reasons,the relations appear tense status in our country,moreover the market economy flourishingly develops,as the result of medical organizations suffering more and more existent pressure.It is an important subject faced for people,especially for medical worker,to righly think the existed defects,and set up the mutual action between doctor and patient.

Antibody drug conjugates (ADCs) are an emerging class of targeted therapeutics with the potential to improve therapeutic index over the traditional chemotherapy. However, it is difficult to control the site and stoichiometry of conjugation in mAb, typically resulting in heterogeneous mixtures of ADCs that are difficult to optimize. New methods for site-specific drug attachment allow development of more homogeneous conjugates and control of the site of drug attachment. In this article, the new literature on development of ADCs and site-specific ADCs is reviewed. In addition, we summarized the various strategies in production of site-specific ADCs.

Coronary fistulae and ventricular septal perforation are very rare clinically, and even less caused by cardiac leiomyosarcoma. A case is reported that a 67-year-old female had cardiac leiomyosarcoma with progressive heart failure and coronary fistulae and ventricular septal perforation. This case was special since all ante-mortem examinations and cardiac surgery failed to detect the presence of any abnormal car-diac mass. Therefore, the malignant cardiac tumors could appear in an invasive form without mass and be one of the causes of the coronary fistulae and ventricular septal perforation.

Objective To explore possible poisonous and harmful effect of excessive iodine intake on skeleton in male rats. Methods Male rat models receiving various amounts of excessive iodine were established for 3,6, 12 months, and quantitative bone histomorphometric parameters and bone mineral density (BMD) of femur and lumbar spine( L1-1 ) were measured by means of dual-energy X-ray absorptimetry in vitro, and rats receiving normal diet were considered as control group. Results There was no significant difference in bone mineral quantity and structural parameters after feeding excessive iodine for 3 months in comparison with control group. The BMD of L1-4 was significantly increased in all animal groups when various amounts of excessive iodide was taken for 6 months (all P

[Objective]To observe the histological characteristics of autologous chondrocytes/human articular cartilage derived scaffold (HACDS) composites for repairing chondral defects in rabbit models. [Methods]A full-thickness articular-cartilage defect (diameter 4 mm,thickness 2 mm) was created in the femoral condyle of rabbits. The rabbits were divided into two groups: control group,HACDS scaffold only,and experimental group,chondrocytes/HACDS scaffold. Fifteen months after implantation,the specimens were observed by inverted phase contrast microscopy,and assessed by staining with haematoxylin-eosin,alcian blue,toluidine blue,safranin O,as well as by the immunohistochemistry of collagen type Ⅱ.[Results]Histologically,the generated neo-cartilage integrated well with its surrounding normal cartilage and subchondral bone in the defects of experimental group at 15 months post-implantation,whereas only fibrous tissue was filled in the defects of control group. Histochemical and immunohistochemical analysis revealed that alcian blue,toluidine blue,safranin,and were obviously positive in the experimental groups. However,alcian blue,toluidine blue,and safranino O were negative in the control group.[Conclusion]The current histological examination demonstrated that an engineered cartilage composed of autologous chondrocytes on HACDS scaffold could be successfully obtained and further applied to repair an articular cartilage defect in a rabbit model.

0.05). Conclusion Epilepsy and short-term or long-term TPM treatment have no effect on serum thyroid hormone levels in adults with epilepsy.

Objective To explore the relationship between syndrome differentiation of diabetic retinopathy (DR) and pattern of visual evoked potential (P-VEP).Methods One hundred and eighty-six eyes from 104 cases of DR were allocated to three groups according to TCM syndrome:qi-yin deficiency (Group A),qi stagnation and blood stasis (Group B) and yin-yang deficiency (Group C).P-VEP induced by various space frequency (0.388?Hz,1.55?Hz) and pictures of various colors (black/white,red/magenta,blue/green) was observed in the three groups and compared with that in the normal control group (Group D).Results One hundred and three eyes in Group A mainly manifested as simple DR,47 eyes in Group B and 36 eyes in Group C mainly manifested as proliferative DR.The latency of P 100 was prolonged and the amplitude was decreassed in all groups of DR,but the latency of P 100 was much prolonged in Group B,the amplitude was much decreased in Group C and the changes were less in Group A.Conclusion P-VEP varies in different TCM syndrome types of DR,and determination of P-VEP under various stimulating conditions may serve as an index of syndrome differentiation of DR.

Objective To investigate the role of interferon ?on smooth muscle cells proliferation and migration after balloon injury. Methods Animal model of rabbit iliac artery balloon injury was set up, smooth muscle cells derived from injured artery were cultured. Smooth muscle cells were divided into four groups ( control, TGF ? 1, IFN ?, TGF ? 1 and IFN ?).Cells from each group were treated with medium or TGF ? 1 (10 ng/ml) and/or IFN ?(500 u/ml) for 72 h separately. Smooth muscle cell proliferation was determined by cell count and MTT, migration of smooth muscle cells was also detected. Matrix metalloproteinase 2 was also detected by zymography. Results Our results showed that, compared with group control(2.875?0.323?10 5 cells/ml,279.9?8.129 ?m), TGF ? 1 increased cell count (4.188?0.239?10 5 cells/ml, P

Objective To investigate the infection of human papilloma virus(HPV) and expression of serum squamous cell antigen (SCCAg) in the follow - up of 120 cervical squamous carcinoma patients who had received operation or operation combined with radiotherapy or only radiotherapy. Methods 120 cases of therapical cervical squamous carcinoma patients were detected HPV - DNA by HC - Ⅱ and serum SCCAg using immunohistochemical method. Results The positive rate of HPV - DNA and serum SCCAg was 49.17% and 17.50% , with a significant difference between them( P 0.05 ). Conclusion HPV - DNA test with HC - Ⅱ for follow - up of cervical squamous carcinoma patients was feasible. It was more sensitive than serum SCCAg. But it suggested that high risk type HPV -DNA test combined with serum SCCAg may be the independent prognostic factors.
