Objective To understand the expressions of transforming growth factor ?1(TGF-?1) and its receptors(T?R) in villi and decidua during early pregnancy and their effects on early embryo development, and explore the mechanism of spontaneous abortion. Methods By immunohistochemical technique, expressions of TGF-?1 and its receptors were determined in villi and decidua from 10 cases of spontaneous abortion women after in vitro fertilization and embryo transfer (IVF-ET group), 20 cases of spontaneous abortion women (spontaneous abortion group), and 20 cases of normal early pregnancy women (control group). Results TGF-?1 and its receptors had high expressions in decidua cells, villus glands and interstitial cytoplasm in all three groups. The average light density of the expressions of TGF-?1 in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.167 and 0.199, 0.198 and 0.201, 0.277 and 0.274, respectively. The intensity of T?R-Ⅰ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.144 and 0.150, 0.202 and 0.201, 0.238 and 0.281, respectively. And the expressions of T?R-Ⅱ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.199 and 0.145, 0.153 and 0.156, 0.300 and 0.301, respectively. The differences between the control group and both abortion groups were all significant (P

Amplification of the human epidermal growth factor receptor 2/neu (HER2/neu) gene and overexpression of the HER2 protein (HER2) have been shown to occur in gastric and gastroesophageal junction adenocarcinoma in a number of studies.With a dismal survival rate,patients with these cancers stand to benefit from the identification of possible molecular targets such as HER2 for both prognostic and therapeutic purposes.Although these and other carcinomas that overexpress HER2 may have a poorer prognosis and exhibit resistance to conventional chemo-therapy,they have also recently been shown to respond to targeted therapy with the anti-HER2 antibody Trastuzumab.Here,the author briefly review the molecular biology,histopathology,diagnostic techniques,and interpretation,as well as the clinical implications of HER2 amplification/overexpression in gastric and gastroesophageal adenocarcinoma.

Most of the current medical humanities education focuses on the moral aspects without good theoreti-cal basis and specific practices on the medical institution and daily life.The article dates back to the origins of So-cial Science based on the concept caregiving put forward by the medical anthropologist Arthur Kleinman,and states that the ultimate purpose of Social Science is to make response to the social suffering and provide caregiving for it.Caregiving as moral experience is response to social suffering and attracts much importance,because it pro-vides both the theoretical basis and practical means for the current medical humanities education.Its characteristics of caregiving as moral experience to social suffering and caregiving as reciprocity meet the demands of current notion of Big health in China.

Objective:To compare the mRNA expression of IRG1in PBMCs from patients with TB, individual with latent infection and healthy controls, and investigate its diagnostic value for Mycobacterium tuberculosis infection.Methods: The mRNA expression of IRG1 from PBMCs stimulated with Mtb-specific antigens was quantitatively detected by quantitative real-time PCR ( qPCR).Receiver-operating-characteristic ( ROC) curves were used to determine the cutoff points yielding the highest specificity and sensitivity,and discriminative ability was evaluated by the area under the ROC curve.Results: The mRNA expression of IRG1 in healthy controls was significantly lower than that in patients with tuberculosis and LTBI ( P<0.05 ).The AUC for using IRG1 mRNA levels (>0.01536 ) to identify Mycobacterium tuberculosis infection was 0.91, with 76.47% sensitivity, 96.30% specificity, LR 20.65,and 85.2% of cases correctly classified.Conclusion: IRG1 may be used as a biomarker for diagnosing Mycobacterium tuberculosis infection.

Objective How to avoid the rejection of the synthetic patch and human tissue has become an urgent problem to be solved.The article investigated thein vivobiocompatibility of polypropylene mesh scaffold with adipose -derived stem cells(ADSCs) in rabbits. Methods Rabbit ADSC suspension were prepared.ADSCs were seeded onto polypropylene mesh scaffolds after passage and amplification and cultured invitro for 1 week .The polypropylene mesh and ADSC fixed polypropylene mesh were implanted respec-tively into the surface of rectus abdominis in rabbits.4 weeks later, adhesion and erosion of the meshes were evaluated, HE staining was used in histological observation and RT-PCR was applied to detect the dynamic changes of VEGF mRNA level.ADSCs were isola-ted from rabbit subcutaneous adipose tissue after collagenase digesting, filtrating and centrifuging. Results The results of flow cy-tometry showed that the expressions of CD44, CD73, CD90, CD45, CD14 and CD34 were 98.54%, 95.32%, 98.49%, 1.21%, 3.01%, 2.14%, respectively.Polypropylene mesh, ADSC-fixed polypropylene mesh had different degrees of corrosion and adhesion , but polypropylene mesh showed denser adhesion.In comparison with polypropylene,ADSC fixed polypropylene meshes induced a mil -der chronic inflammation response,with lower scores for inflammation (1.1 ±0.2 vs 0.6 ±0.1, P=0.001), higher scores for neovas-cularization (17.0 ±0.0 vs 2.6 ±0.3, P=0.000) and fibroblastic proliferation(0.9 ±0.1 vs 2.2 ±0.2, P=0.001).Relative a-mounts of VEGF mRNA of were significantly lower for ADSC-fixed polypropylene compared with the remaining polypropylene meshes (t=94.6, P<0.05). Conclusi on Polypropylene mesh scaffold with ADSCs exhibits excellent cellular compatibility and have a bright future in clinical practice.
