Partial hydatidiform mole and coexisting fetus is a rare entity with antecedent high risk of maternal and fetal complications, and risk of persistent trophoblastic disease in later life. Here, we report a case of twin pregnancy with live fetus identified as 45,X and normal placenta and another partial mole. Ultrasound scan at 10 weeks showed a hydrops fetus with a focal area of multicystic placenta. The patient underwent chorionic villus sampling and amniocentesis for chromosomal analysis, and the result was 45,X. Based on these finding, the patient then underwent induced abortion. Pathological examination (immunohistochemical staining) of the placenta confirmed the partial mole. This report suggests that careful prenatal ultrasonography and appropriate karyotyping in a molar pregnancy and coexisting fetus enable early diagnosis and may be beneficial for prognosis.

Organ transplantation is currently the most fundamental treatment for organ failure, but there is a shortage of organ supply compared to those in need. Regenerative medicine has recently developed a decellularization technique that overcomes the limitations of conventional organ transplantation and attempts to reconstruct damaged tissues or organs to their normal state. Several decellularization methods have been suggested. In this experiment, the decellularization methods were used to find effective decellularization methods for humanlike porcine placenta. The optimal conditions for decellular support are low DNA content and high glycos amino glycans (GAGs) and collagen content. In order to satisfy this condition, SDS and Triton X-100 and SDS + Triton X-100 were used as the detergent used for decellularization in this experiment. The contents were compared according to the decellularization time (0, 12, 24, 48 and 72 hours), and the concentrations of SDS (0.2, 0.5, 0.7 and 1.0%) were mixed in 1.0% Triton X-100 to analyze the contents. When decellularized using SDS and Triton X-100, respectively, it was confirmed that the contents of DNA and GAGs were opposite to each other. And decellularization treatment for 24 hours at 0.5% SDS was able to obtain an effective decellular support. If decellularization studies of various detergents can be obtained an effective decellular support, and furthermore, cell culture experiments can confirm the effect on the cells.

Objective : This study was undertaken to determine whether Hominis Placenta(HP) aqua-acupuncture exerts renoprotective effect on diabetic nephropathy induced by streptozotocin(STZ) in rats. Methods : In order to study the renoprotective effect of HP aqua-acupuncture, experimental animals were divided into 5 groups and treated for 2 weeks as follows: control group was injected subcutaneously by saline aqua-acupuncture into Sinsu(BL23) in STZ induced diabetic rats, 5% HP aqua-acupuncture group was injected subcutaneously by 5% HP aqua-acupuncture into Sinsu(BL23) in STZ induced diabetic rats, 10% HP aqua-acupuncture group was injected subcutaneously by 10% HP aqua-acupuncture into Sinsu(BL23) in STZ induced diabetic rats, normal group was injected subcutaneously by saline aqua-acupuncture into Sinsu(BL23) in normal rats, and Captopril group was administrated with captopril at a dose of 50mg/kg in STZ induced diabetic rats. Results : While HP aqua-acupuncture did not reduce any body weight, index of kidney hypertrophy, the plasma glucose concentration and BUN respectively, HP aqua-acupuncture showed lowering urinary albumin excretion rate and serum creatinine as compared with the control group. Gene and protein expressions of $TGF-{\beta}1$ and fibronectin in kidney, one of the extracellular matrix proteins were investigated. There were significant differences in expression levels in HP aqua-acupuncture group as compared with the control group, and $100{\mu}g/m{\ell}$ and $500{\mu}g/m{\ell}$ of HP depressed apoptosis, showing in a dose dependent manner. In the HE staining, HP aqua-acupuncture inhibited the injury of glomerulus and proximal convoluted tubule. Conclusions : HP aqua-acupuncture showed the renoprotective effect possibly through suppressions of $TGF-{\beta}1$ and fibronectin expressions in kidney.

Angiogenesis is essential for solid tumor growth and progression. Among the pro-angiogenetic factors, vascular endothelial growth factor(VEGF), also known as vascular permeability factor, is the most important as a mitogen for vascular endothelium. The VEGF family of molecules currently consists of six growth factors, VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, and placenta growth factor(PlGF). Over-expression of PlGF is associated with angiogenesis under pathological conditions such as ischemia, inflammation, and cancer. Hence, the goal of this study is to identify the correlation of clinicopathlogical factors and the up-regulation of PlGF expression in oral squamous cell carcinoma. We studied the immunohistochemical staining of PlGF, PlGF gene expression and a real time quantitative RT-PCR in 20 specimens of 20 patients with oral squamous cell carcinoma. The results were as follows. 1. In the immunohistochemical study of poorly differentiated and invasive oral squamous cell carcinoma, the high level staining of PlGF was observed. And the correlation between immunohistopathological PlGF expression and histological differentiation of specimens was significant (Pearson correlation analysis, significance [r] >0.6, P < .05). 2. In the PlGF gene RT-PCR analysis, PlGF expression was more in tumor tissue than in adjacent normal tissue. Paired-samples analysis determined the difference of PlGF mRNA expression level between the cancer tissue and the normal tissue (Student's t - test, P < .05) These findings suggest that up-regulation of the PlGF gene may play a role in progression and local metastasis in invasive oral squamous cell carcinoma.

목 적: 영양막세포의 과도한 세포자멸사는 태반의 발달뿐 아니라 산과 질환을 유발하는 요인으로 알려져 있다. X-linked inhibitor of apoptosis (XIAP)은 임신 기간 동안 영양막세포의 세포자멸사와 관련되어 있다고 알려져 있으나, 자간전증을 유발하는 인자인 저산소성과의 관계에 관한 연구는 미흡한 실정이다. 본 연구의 목적은 XIAP가 정상 태반과 자간전증 산모의 태반에서 발현 양상의 차이를 분석하고, 저산소 상태에 노출된 HTR-8/SVneo 영양막세포주에서의 XIAP 기능을 분석하고자 하였다. 연구방법: XIAP 발현을 분석하고자, 정상 태반 (n=15), 중기 자간전증 태반 (n=11), 그리고 말기 자간전증 태반 (n=15) 조직을 수집하여 RT-PCR, 면역조직화학법, 그리고 Western blot 등을 실시하였다. 저산소성 상태에서 XIAP의 기능을 확인하고자 HTR-8/SVneo 영양막세포주에 1% 산소가 공급되는 hypoxia 상태에 노출시킨 뒤 12시간, 24시간 후에 각 세포자멸사 관련 유전자들의 발현을 fluorescence-activated cell sorting (FACS)와 Western blot 분석 등을 실시하였다. 결 과: XIAP는 태반의 합포영양막세포와 포합체결절에서 발현이 관찰되었으며, 정상 태반보다 자간전증 태반에서의 발현이 현저히 감소됨이 관찰되었다 (p<0.05). 또한, 저산소 상태에 노출된 HTR-8/SVneo 영양막세포주에서 감소된 XIAP 발현은 세포질에서 핵으로의 이동에 따라 세포자멸사를 유발하는 단백질들의 발현이 증가됨이 관찰되었다. 결 론: XIAP의 발현은 태반 발달 및 자간전증 태반에서 XIAP 유전자의 발현은 감소되었으며, XIAP의 저하로 인한 caspase-9의 증가가 자간전증 태반에서의 세포자멸사는 더 많이 유도되었음을 확인할 수 있었다. 또한, 저산소 상태에 의해 XIAP의 발현이 감소되었으며, XIAP 단백질의 세포질에서 핵으로의 위치 변화는 영양막세포의 세포자멸사에 중요한 역할을 하는 것이 관찰되었고, 이는 자간전증의 진단에 유용한 마커로써의 활용되기 위한 기본적인 자료로 활용될 수 있을 것으로 판단된다.

Objective:Cervical cancer is one of the major causes of mortality of Uyghur women in Xinjiang, China. Although increased expression of orexin receptor (OxR), known to be strongly expressed in human placenta, has a proven relation to some cancers, there have been few studies of cervical cancer. Thus, we explored this question by evaluating the expression of orexin receptor as a biomarker for screening early stage of cervical cancer in Uyghur women with highest occurrence rate of cervical cancer in China. Study Design: We used polymerase chain reaction (PCR) and immunohistochemical staining to determine the expression of both Ox1R and Ox2R in cervical cancer and cervicitis biopsies collected from Uyghur women infected with human papilloma virus (HPV)16. The expression rate was compared between cervical cancers of low, intermediate and high differentiation and cervicitis. Results:Although there was no significant difference in the expression rate of Ox1R between groups, Ox2R was significantly overexpressed in cervical cancer patients when compared to the cervicitis group. Ox1R was negative in normal human placenta while Ox2R was positive. Conclusions: While expression of Ox1R had no correlation with invasion or metastatic potential, Ox2R demonstrated elevation in cervical cancer with heterogeneity in groups with different metastatic potential, in the human placenta as well, implying that it might serve as an indicator of invasive capacity along with other indices.

Reprogramming errors, which appear frequently in cloned animals, are reflected by aberrant gene expression. We previously reported the aberrant expression of TIMP-2 and PBEF in cloned placenta and differential expression of PBEF genes during pregnancy. To examine the epigenetic modifications that regulate dynamic gene expression in developing placentae, we herein analyzed the mRNA and protein expression levels of PBEF and TIMP-2 in the placentae of normal mice during pregnancy and then examined potential correlations with epigenetic modifications. DNA methylation pattern analysis revealed no difference, but ChIP assays using antibodies against H3-K9/K14 and H4-K5 histone acetylation revealed that the H3-K9/K14 acetylation levels, but not the H4-K5 acetylation levels, of the TIMP-2 and PBEF loci were significantly correlated with their gene expression levels during placentation in normal mice. These results suggest that epigenetic changes may regulate gene expression level in the developing placentae of normal mice and that inappropriate epigenetic reprogramming might be one cause of the abnormal placentae seen in cloned animals.

Background Rosa damascena, a type of herb, has been used for wound healing in Eastern folk medicine. The goal of this study was to evaluate the effectiveness of rose placenta from R. damascena in a full-thickness wound model in mice. Methods Sixty six-week-old C57BL/6N mice were used. Full-thickness wounds were made with an 8-mm diameter punch. Two wounds were made on each side of the back, and wounds were assigned randomly to the control and experimental groups. Rose placenta ($250{\mu}g$) was injected in the experimental group, and normal saline was injected in the control group. Wound sizes were measured with digital photography, and specimens were harvested. Immunohistochemical staining was performed to assess the expression of epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), transforming growth factor-${\beta}1$ (TGF-${\beta}1$), and CD31. Vessel density was measured. Quantitative analysis using an enzyme-linked immunosorbent assay (ELISA) for EGF was performed. All evaluations were performed on postoperative days 0, 2, 4, 7, and 10. Statistical analyses were performed using the paired t-test. Results On days 4, 7, and 10, the wounds treated with rose placenta were significantly smaller. On day 2, VEGF and EGF expression increased in the experimental group. On days 7 and 10, TGF-${\beta}1$ expression decreased in the experimental group. On day 10, vessel density increased in the experimental group. The increase in EGF on day 2 was confirmed with ELISA. Conclusions Rose placenta was found to be associated with improved wound healing in a mouse full-thickness wound model via increased EGF release. Rose placenta may potentially be a novel drug candidate for enhancing wound healing.
