BACKGROUND: Cell apoptosis and ventricle reconstitution following myocardial infarction are of mutual cause-effect, and they cause vicious cycle. How to reduce the apoptosis events following myocardial infarction is one of keys to saving heart function.OBJECTIVE: To observe the effect of umbilical cord blood mesenchymal stem cell (UCBSMC) transplantation on remaining myocardial tissue of dogs with acute myocardial infarction.DESIGN: A randomized controlled observation.SETTING: Department of Cardiothoracic Surgery, Xinhua Hospital.MATERIALS: This study was carried out in the Central Laboratory of Xinhua Hospital from October 2005 to May 2007.Thirty-six adult hybrid dogs, male and female in half, were provided by the Animal Experimental Center of Xinhua Hospital.METHODS: Thirty-six dogs were divided into cell transplantation group and control group, with 18 dogs in each according to table of random digit. Mesenchymal stem cells were isolated from the umbilical cord blood of full-term pregnant hybrid dogs, cultured and amplified. Then, they were labeled with Laz gene, in vitro induced with 5-azacytidine, and transplanted into the dogs with acute myocardial infarction in the cell transplantation group. Rats in the control group were injected with the same amount of normal saline. Each dog was euthanized by anesthesia for harvesting myocardial specimen 1,4 and 8 weeks after transplantation.MAIN OUTCOME MEASURES: ① Remaining and apoptosis index detected by TUNEL method. ② Myocardial cell volume and histomorphology detected by confocal microscopy. ③ Histological change of myocardial collagen network detected by haematoxylin-basic fuchsin-picric acid staining.RESULTS: Thirty-six involved experimental dogs all entered the stage of final analysis. ①The apoptosis index in the cell transplantation group was significantly lower than that in the control group 1, 4 and 8 weeks after cell transplantation (P ＜0.05). ② Myocardial cell volume in the cell transplantation group 1, 4 and 8 weeks after cell transplantation was significantly larger than that in the control group (P ＜ 0.05). ③ Collagen fiber in the myocardial tissue of dogs in the cell transplantation group was arranged in order and regularly, and in contrast that in the control group was not, and fibers in the control group fused partially.CONCLUSION: UCBSMC transplantation reduces the apoptosis of myocardial cells, promotes the hypertrophy of remaining myocardial cells, regulates myocardial collagen network and improves heart function.

Objective To investigate the oncologic and reproductive outcomes after progestin treatment of complex endometrial hyperplasia(CEH) and grade 1 endometrial carcinoma(EC).Methods In a retrospective study, data were obtained for patients with CEH or grade 1 EC at presumed stage IA(without myometrial invasion) who wished to preserve fertility and were treated at the Peking Union Medical College Hospital, China, between January 1, 2000 and December 31, 2011.Patients had received oral medroxyprogesterone acetate(250-500 mg/d) or megestrol acetate(160-480 mg/d) for at least 6 months.Results Among 55 included patients, median age was 32 years(range 21-41 years).41(75%) achieved complete response after a median period of 6(3-24) months.Complete response was less frequent among obese than nonobese patients(4/12 [33%] vs 37/43 [86%];P=0.001).Disease recurrence was recorded in 10(24%) patients with complete response;the 5-year recurrence-freesurvival rate was 71%.Among the 33 patients who retained a desire to conceive, 17(52%) became pregnant.Conclusions Fertility-sparing management with oral progestin is effective and safe.Obesity is associated with a lower probability of long-term success.

In this paper, metabolic networks of the Corynebacterium glutamicum GWY020 and the two de-rivatives carrying additional mutations HUI821and GUI089 were established and modified. The concentra-tions of extra-cellular metabolites were determined under sub-steady-state (50 h~52 h) of the batch culture. The metabolic flux distribution maps of the three strains were obtained, compared and analyzed. These re-sults indicate that the introduction of analog supersensitive marker or analog resistant marker skew the metabolic flux towards the formation of L-Arginine. This study revealed the usefulness of the metabolic flux analysis as a tool for verification of existing production strains. The analysis may play an important role in helping us to rationally re-design metabolism for further improvement of fermentation process.

Some unhealthy life habits, such as long-term smoking, heavy drinking, sexual overstrain and frequent stay-up could induce the Yin deficiency symptoms of zygomatic red and dysphoria. Stems of Dendrobii officinalis flos (DOF) showed the efficacy of nourishing Yin. In this study, the hyperthyroidism Yin deficiency model was set up to study the yin nourishing effect and action mechanism of DOF, in order to provide the pharmacological basis for developing DOF resources and decreasing resource wastes. ICR mice were divided into five groups: the normal control group, the model control group, the positive control group and DOF extract groups (6.4 g · kg(-1)). Except for the normal group, the other groups were administrated with thyroxine for 30 d to set up the hyperthyroidism yin deficiency model. At the same time, the other groups were administrated with the corresponding drugs for 30 d. After administration for 4 weeks, the signs (facial temperature, pain domain, heart rate and autonomic activity) in mice were measured, and the facial and ear micro-circulation blood flow were detected by laser Doppler technology. After the last administration, all mice were fasted for 12 hours, blood were collected from their orbits, and serum were separated to detect AST, ALT, TG and TP by the automatic biochemistry analyzer and test T3, T4 and TSH levels by ELISA. (1) Compared with the normal control group, the model control group showed significant increases in facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01), serum AST, ALT (P < 0.01), T3 level (P < 0.05), TSH level (P < 0.05) and notable deceases in pain domain (P < 0.01), TG level (P < 0.01). (2) Compared with the model control group, extracts from DOF (6 g · kg(-1)) could notably reduce facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01) and AST (P < 0.05) and enhance pain domain (P < 0.01) and TG (P < 0.01). Extracts from DOF (4 g · kg(-1)) could remarkably reduce AST and ALT levels (P < 0.01, 0.05). Extracts from DOF (6 g · kg(-1) 4 g · kg(-1)) could significantly reduce T3 and increase serum TSH level (P < 0.05). DOF could improve Yin deficiency symptoms of zygomatic red and dysphoria in mice as well as liver function injury caused by overactive thyroid axis. According to its action mechanism, DOF may show yin nourishing and hepatic protective effects by impacting thyroxin substance metabolism, improving micro-circulation and reducing heart rate.

Background Studies demonstrated that human amniotic epithelial cells (AECs) have some characteristics of embryonic stem cells and they were used to re-establish the surface of eyes. Human AECs may serve as new seed cells in tissue engineering for corneal epithelium reconstitution in the future. Objective The present study was to investigate the application value of human amniotic epithelium cells transfected by lentiviral vectormediated enhanced green fluorescent protein (EGFP) gene as new seed cell source for engineering the corneal surfacelayer. Methods Lentiviral vector carrying the objective gene EGFP was transfected into human amniotic epithelial cells (pLenti6/V5-DEST),and the transient expression of the transgene in the human amniotic epithelial cells was observed under the fluorescence microscope. Flow cytometry was used to detect the positive expression rates of EGFP in transfected cells. The transfected human amniotic epithelial cells were seeded onto the fresh corneal stromal surface of New Zealand white rabbit and cultured in vitro. The stem cell deficiency ( SCD ) models were established by cutting off the limbus of cornea in 20 eyes of New Zealand white rabbits, and the model rabbits were then divided into 2 groups randomly. The transplanted grafts carrying the pLenti6/V5-DEST-EGFP gene-transferred human amniotic epithelium cells were regarded as the pLenti6/V5-DEST-EGFP group, and the corneal stroma graft without any epithelial cell served as the control group. The opacity of stroma and corneal conjunctivalization and vascularization were observed daily. The rabbits' eyes were extracted one month after operation. The expression of EGFP in the cornea was detected under the fluorescence microscope, and the expression of CK8, CK18 and CK12 in cornea was detected by immunohistochemical staining. Results The shape of the transferred human amniotic epithelial cells resembled normal human amniotic epithelial cells. 48 hours after the transient transfection of EGFP presented with the highest expression level throughout the observation duration, with a positive expression rate of EGFP of 61.5% ,showing significant differences in comparison with that of 12 ( 5.24% ) , 24 ( 38.27% ) or 96 ( 39. 10% ) hours ( P ＜0. 05) post-transfection; but no obvious difference was found in the positive rate of transiently transfected EGFP between 48 hours and 72 hours ( 58.36% ) ( P＞0. 05 ). Six cornea grafts were clear in 1 month and two corneas were rejected during the observation period in the pLenti6/V5-DEST-EGFP group. A few new blood vessels were seen around the graft. Ten corneas of the control group became opaque and cloudy with new blood vessels growth around the grafts. Imunohistochemistry revealed the positive expressions of CK8, CK1 8 and CK12 in the corneal epithelial layer in the pLenti6/V5-DEST-EGFP group. However,the expression of CK12 was absent in the control group. Conclusion Human amniotic epithelium cells transfected with the pLenti6/V5-DEST-EGFP gene is a new and ideal feed cell type to reconstruct the corneal surface layer. Lentivirus is a relatively safe gene transfection vector.

Chronic obstructive pulmonary disease (COPD), a common preventable and treatable disease, is characterized by airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways. Its main pathological manifestations include airway inflammation, mucus hypersecretion, oxidative stress and apoptotic epithelial cells. Recent research suggests that MAP kinases and Keap1-Nrf2-ARE signaling pathway are involved in the pathological process of inflammation and oxidative stress. This review explores the potential role of the cross talk of these signaling pathways in airway inflammation, mucus hypersecretion, oxidative stress and apoptotic epithelial cells. To clarify the roles of cross talk between MAP kinases and Keap1-Nrf2-ARE signaling pathway, we also focus on the drugs related to that in the treatment of COPD, and it provides ideas for more drug research in the treatment of COPD.
