Genes associated with retinoid-interferon mortality (GRIM) are a group of genes,and GRIM-19 is one of the core genes.Studies have found that GRIM-19 is down-regulated in many types of tumors,and may be a new type of tumor suppressor and a new target for chemotherapy in tumors.

Objective To investigate the expression and clinicopathological features of gene associated with retinoid-interferon mortality-19 (GRIM-19) in epithelial ovarian carcinoma.Methods The expression of GRIM-19 gene in tissues from 138 cases of epithelial ovarian carcinoma,102 cases of benign ovarian epithelial tumor and 46 cases of normal ovarian tissues were detected by Immunohistochemistry and Western blot methods.Assembled clinical survival data were analyzed with Kaplan-Meier and Cox regression models.Results The expression level of GRIM-19 in epithelial ovarian carcinoma (3.4 ± 2.0) was lower than that in benign ovarian tumor tissues (4.7 ± 2.9) and that in normal ovarian tissues (7.5 ± 2.2 ; P ＜0.01).The level of GRIM-19 expression was related to the survival time of epithelial ovarian carcinoma patients by Kaplan-Meier analysis (P =0.002).The shorter survival time of epithelial ovarian carcinoma patients was significantly associated with the level of GRIM-19 expression (P =0.001),clinical stage (P =0.001),volume of ascites (P =0.023) and the largest diameter of the primary tumor lesion (P =0.044) by Cox regression models.Conclusions The low expression of GRIM-19 in the epithelial ovarian carcinoma suggests that GRIM-19 may be a key gene involved in its carcinogenesis.The expression level of GRIM-19 may be also an independent prognostic factor for epithelial ovarian carcinoma patients.

Objective To evaluate the clinical characteristics of epithelioid trophoblastic tumor (ETT).Methods Six cases of ETT treated in Women's Hospital,School of Medicine,Zhejiang University from 2005 to 2007 were retrospectively analyzed,together with a literature review.Results Six cases of ETT were diagnosed pathologically after surgery.The age of patients ranged from 27 to 46 years.The most common presentation was abnormal vaginal bleeding(5/6).The preceding gestational events were hydatidiform mole in 1 case,abortion in 2 cases,and term delivery in 3 cases.The interval between the preceding gestation and the diagnosis of ETT ranged from 15-48 months.The serum human chorionic gonadotropin(hCG)level was 46-121 147 IU/L.Four cases presented with metastasis,including lung metastasis in all of the 4 cases,liver metastasis in 1 case,and pancreas metastasis in another 1 case.The main therapies were surgery combined with chemotherapy.All of the 6 cases received total abdominal hysterectomy.and 1 case also had lung lobectomy.One ease had a recurrence but refused any treatment again,and was lost to follow up;the therapy of 1 case unfinished;another 4 cases were without evidence of disease 9 to 19 months after surgery.Condusions The confirmation of ETF diagnosis is difficult before surgery.Surgical management is mostly recommended in ETT. The role of chemotherapy in ETT is not clear yet.

Objective To investigate the expression of low molecular mass polypeptide-2 (LMP2)and protein phosphatase 1A (PPM1A) in gestational trophoblastic disease and elucidate their predictive value in malignant transformation of hydatidiform mole. Methods The expressions of LMP2 and PPM1A protein in 196 complete hydatidiform moles (in which 28 cases with malignant transformation) , 7 invasive moles, 5 choriocarcinomas and 20 normal chorionic villus were detected with the method of En Vision immunohistochemistry. Their clinicopathologic data were retrospectively analyzed. Results LMP2 and PPM1A protein expressed in cytotrophocytes, syncytiotrophoblast and extravillous trophoblast. The level of LMP2 expression in deteriorative hydatidiform mole was significantly higher than that in non-deteriorative hydatidiform mole or normal chorionic villus (6. 79 ±2. 38, 5.26 ±2.63 and 3. 10 ±1.65, all P <0. 01),while there were no difference compared with gestational trophoblastic neoplasms (6. 42 ±2. 68, P=0. 113).The level of PPM1A expression was highest in normal chorionic villus, and decreased gradually in hydatidiform mole (non-deteriorative and deteriorative) and gestational trophoblastic neoplasms (6. 30 ±2. 98, 4. 93 ± 2. 50, 4. 43 ± 2. 04 and 3. 33 ± 2. 06, all P < 0. 01); the level of PPM1A expression in deteriorative hydatidiform mole was significantly lower than that in non-deteriorative hydatidiform mole (P=0.001). The expression of LMP2 protein was correlated to theca lutein ovarian cyst, the expression of PPM1A protein was related with uterine size (P < 0. 05) . While, there was no correlation between the expressions of the two proteins (P >0. 05). Conclusions High expression of LMP2 and low expression of PPM1A might play an important role in the motility and invasiveness of trophohlast cells and malignant transformation of hydatidiform mole. Testing the expression of LMP2 and PPM1A in hydatidiform mole tissues of initial uterine evacuation might be have some reference significance in judging outcomes of hydatidiform mole.

Objective To assess the high risk factors associated with the positive margin of conization in patients with cervical intraepithelial neoplasia (CIN). Methods From January 2000 to February 2008, 1699 consecutive patients with CIN undergoing conization was reviewed retrospectively in order to analyze the relationship between the positive margin of conization with clinical prognostic factors,such as patients age, disease grade, size of lesion, the procedure of excision and menopause. X<'2> tests was used to compare the different frequencies of factors in groups of positive and negative margin conization, then seven factors with positive margin were processed into unconditional logistic regression analysis. Results The rate of the positive margin in 1699 patients was 14.01% (238/1699). The mean age of patients with positive margins was (39±9 ) years old, while patients with negative margins was ( 39±8 ) years old, which didn't reach statistical difference(P>0.05). The rate of the positive margin was 8.63% in cold knife cone (CKC) and 18.66% in loop electrosurgical excision procedure (LEEP), which showed significant difference( P<0.01 ). Among 1699 patients, 90 patients were with CIN Ⅰ ,339 patients were with CIN Ⅱ ,1113 patients were with CIN Ⅲ [ including 972 with severe dysplasia and 141 with cancer in situ(CIS) ],87 patients were with cervical cancer stage Ⅰ al, 70 patients were with stage Ⅰ a2 or advanced stages. The rate of positive margin was 1.11% ( 1/90), 3.83% ( 13/339), 10.70% (104/972), 26.24% (37/141),35. 63% (31/87) and 74.29% (52/70),respectively. There was statistic difference among them, except CIN Ⅰ and CIN Ⅱ . When combined CIN Ⅰ with CIN Ⅱ , then compared with CIN Ⅲ, cervical cancer withⅠ al and Ⅰ a2, it also showed statistical difference (P<0.05 ) . The rate of positive margin in postmenopausal women was 21.54% (28/130), which was significantly higher than 13.38% (210/1569)in premenopausal women (P=0.010 ). The logistic regression analysis showed that the procedure of excision, grade of disease, size of lesion, surface of cervix, and menopause were high risk factors associated with the positive margin, the risk ratio were 5.147, 3.048, 1.271, 1.905 and 1.860, respectively.Conclusions High grade, the extent of CIN disease, LEEP and postmenopausal age are high-risk factors associated with positive margin in patients treated by conization. It should be warranted in those patients when designing conization treatment.

In order to set up a base for stem cells to be widely used in clinical medicine, we tried to optimize, in this study, the technique that induces human mesenchymal stem cells (hMSCs) to differentiate into neural stem cells by using cerebrospinal fluid (CSF) from the different groups. After the induction, presence of neural stem cells was confirmed with microscope observation, flow cytometry analysis, immunohistochemistry and fluorescent immunohistochemistry. At the same time, we also compared and analysed the data of the number of stem cells when it totally met the requirements for clinical treatment and the days required. At last, we confirmed that hMSCs could be induced to differentiate into neural stem cells, and that the number of cells totally met the requirements for clinical treatment. But there were some differences both in the number of cells and the days required. Among the groups, the group that marrow mesenchymal stem cells from patients own induced by CSF from healthy volunteers used the shortest time and the quantity of the cells was significantly higher than those of the others.

Objective To analyze the association of serum CA125 level at the different phases with recurrence and survival, for providing simple and efficient methods about predicting recurrence and prognosis in epithelial ovarian cancer.Methods The clinical-pathological data from 151 patients were collected, who were histologically confirmed as primary ovarian cancer between Jan 2002 and Dec 2005.All the patients were followed up.The relationship between serum CA125 level at different phases and clinical-pathological data were analyzed, including prognostic associated factors, 2-year or 5-year recurrent rate, 5-year survival rate, progression-free survival times, and overall survival times.Results Serum CA125 level at pre-surgery and the end of 3-course chemotherapy were associated with most of the clinical-pathological parameters,included stage, pathological grade, amount of ascites, residual tumor size, type of recurrence, 2-year and 5-year recurrent rate, and 5-year survival rate ( all P ＜ 0.05 ).Progression-free survival and overall survival times were shorter in the patients with higher CA125 level at pre-surgery or abnormal CA125 level at the end of 3-course chemotherapy (P ＜0.01 ).There was no relationship between the ratio of CA125 level at pre- and post-surgery and recurrence or prognosis ( all P ＞ 0.05).Conclusion Serum CA125 level at pre-surgery and the end of 3-course chemotherapy can be used for predicting the recurrence and prognosis of epithelial ovarian cancer.

OBJECTIVE:To compare the quality control index between Jinzhen Suanzao teabag and decoction,and explore the alternative supplement of teabag to decoction. METHODS:The test sample solutions of Jinzhen Suanzao teabag and decoction were prepared by hot-maceration method and water-decoction method. The contents of water soluble extract and total flavonoids were de-termined and compared between 2 kinds of preparation. The leaching rates of teabag were investigated at different soak time(0,5, 10,15,20,25,30 min) to optimize soaking time. RESULTS:The average content of water soluble extract were 50.56% and 44.45%(P<0.05) respectively for the teabag and decoction. The total flavonoids content were 0.64 mg/g and 0.69 mg/g (P<0.05). The dissolution amount of teabag were increasing and leaching rate increased within first 20 min,and reached balance gradu-ally 25 min later. CONCLUSIONS:According to the convenience of use and results of each index,the difference in quality control index is not great between 2 kinds of preparation. Teabag can be as the supplement of decoction.

BACKGROUND:Islet and islet cel transplantation for the treatment of diabetes has achieved effect, but the research is limited dut to the shortage of islet and immune rejection. OBJECTIVE:To observe the effect of transplantation of islet-like cells that in vitro differentiated from bone marrow mesenchymal stem cells on the treatment of diabetes in rats. METHODS:The rat bone marrow mesenchymal stem cells were induced with basic fibroblast growth factors and hepatocyte growth factors, and then received immunocytochemistry staining to detect the induction. The Sprague Dawley rats received intraperitoneal injection of streptozotocin to establish the diabetes models. After modeling, the rats were randomly divided into control group and experimental group (transplanted with induced islet-like cells). The experimental group was transplanted with the induced islet-like cells through renal capsule, and the control group was transplanted with normal saline in the same dose. The blood glucose and body mass of the diabetes rats were observed after transplantation. RESULTS AND CONCLUSION:The bone marrow mesenchymal stem cells could differentiate into islet-like cells after in vitro induced with basic fibroblast growth factors and hepatocyte growth factors. There was no significant change in blood glucose of the control group after transplantation (P>0.05), and the blood glucose of the rats in the experimental group was significantly decreased compared with the control group (P<0.05). The bone marrow mesenchymal stem cells can differentiate into islet-like cells after in vitro induced with the induction system containing basic fibroblast growth factors and hepatocyte growth factors, and the islet-like cells have a certain ability of insulin secretion. The transplantation of induced islet-like cells after transplanted into the diabetes rats through renal capsule can decrease the blood glucose level of the rats.
