Objective To investigate the relationship between the Vimentin expression and lymph node metastasis of cervical cancer in order to explore the possibility of its predictive value on the lymph node metastasis and parametrial infiltration. Methods The expression of Vimentin in cervical cancer tissue microarray chip which contains 78 cases was evaluated by immunohistochemistry method to study the relationship between the expression and lymph node metastasis and parametrial infiltration of cervical cancer. Results The expression of vimentin in 78 cases of cervical cancer tissue was 30/78 (38.5%) .The expression of vimentin in cervical cancer was significantly related to lymph node metastasis and parametrial infiltration respectively. The expression of Vimentin in lymph node metastasis positive group was 15/31 (48.4%), which were significantly higher than that in lymph node metastasis negative group. The expression of Vimentin in parametrial infiltration positive group was 17/32 (53.1%), which were significantly higher than that in parametrial infiltration negative group ( <0.05) . Conclusions The expression of vimentin in cervical cancer tissue is correlated with lymph node metastasis and parametrial infiltration. It is an effective way to predict the lymph node metastasis and parametrial infiltration in cervical cancer patients.

Objective To track superparamagnetic iron oxide (SPIO)-labeled pancreatic islet cells in rats using 3.0T magnetic resonance imaging (MRI), and to detect the survival and rejection of grafts after transplantation. Methods Twenty male Wistar rats and 5 male Lewis rats were included in the study. SPIO-labeled pancreatic islet cells were tracked using a GE 3.0T Signa Excite MRI scanner with an animal coil. The images of SPIO-labeled islet cells in rats after transplantation were compared with those of the unlabeled ones. FSE T2WI sequence and GRE T2*WI sequence were used for the detection. The sensitivity of images for detection of grafts was also compared. SPIO-labeled pancreatic islet cells isolated from Wistar and Lewis rats were transplanted into the liver of Wistar rats. Afterwards, the survival and rejection of islet cells were observed sequentially in these two growps. The rats in the syngeneic group were sacrificed 3 months post-transplantation, while the rats in the allogeneic group were sacrificed 3 weeks post-transplantation. MRI of the grafts were correlated with the pathological results. Results SPIO-labeled pancreatic islet cells were seen on MRI as distinct homogenous, hypointense spots in the liver. GRE T2*WI were more sensitive to the detection of SPIO-labeled islet cells than FSE T2WI. The relative count of hypointense spots in the syngeneic group were (90.03±9.52)%, (92.87±18.21)% and (86.25±24.81)%, respectively at 1 week, 2 weeks and 3 weeks after transplantation, while the relative count in the allogeneic group were (41.40±15.41)%, (33.41±14.01)% and (23.58±16.78)%, respectively. The difference between these counts was statistically significant (P<0.01). Iron particles were detected only in the SPIO-labeled cells. Three months post-transplantation, the grafts were found well-preserved in the liver of the rats of the syngeneic group, while only a few grafts were found in that of the allogeneic group. Conclusions MRI can be used to track SPIO-labeled islet cells in vivo, and has significant value in detecting the survival and rejection of grafts after transplantation in rats.

[Summary] Drug naive, newly diagnosed type 2 diabetic subjects were randomized to Saxagliptin/Metformin / Rosiglitazone(Triple Therapy, n=23) or insulin 70 30 mix group(Intensive Insulin Therapy) (n=21) for 24 weeks. How did the 2 therapies influence fasting blood glucose, fasting insulin, C-peptide, and glucagon levels and the change of body weight were compared. This study was aimed to explore the comparative glycemic efficacy and impact on α/ β-cell function of two different antidiabetic therapies, triple combination therapy using saxagliptin/metformin/ rosiglitazone and intensive insulin therapy, for newly diagnosed type 2 diabetes mellitus. The results indicated that fasting blood glucose, HbA1C , insulin resistance index 2(HOMA 2-IR), glucagon and body mass index level were significantly decreased, and insulin secretion index 2 ( HOMA 2-% β) was increased significantly( P <0. 05) in triple therapy group, and the decreasing extent of HOMA 2-IR, glucagon, and body mass index were significantly greater than that in the intensive insulin group(P<0. 05). Triple therapy group has a stronger effect of reducing insulin resistance, as well as on inhibiting glucagon and promoting weight loss.

Objective To investigate the efficiency of radiofrequency ablation (RFA) and microwave ablation (MWA) in treating uterine leiomyoma.Methods The clinical data of thermal ablation with RFA and MWA were retrospectively analyzed in 42 patients.All patients were followed up at least 12 months to observe the therapeutic effects after the treatment.The changes of vital signs and the size of uterine leiomyoma,the score of uterine leiomyoma symptom and quality of Iife(UFS-QOL) were compared after RFA or MWA,the two thermal ablations techniques of clinic efficiency and influence on complications were analyzed.Results 23 patients received treatment of RFA and 19 patients received MWA,the visual analogue scale(VAS)during operation and postoperation were statistically significant differences between the two groups(P ＜0.05).The sizes of uterine leiomyoma were significantly reduced after the thermal ablation,the differences of volume within two groups in different time were statistics significance(P ＜0.05),but there were no statistics significance differences between two groups (P ＞0.05).The symptoms in two groups were improved significantly after treatment and the scores of UFS-QOL were no statistics significance differences between two groups (P ＞0.05).Conclusions Both of RFA and MWA have significant clinic efficiency in treating uterine leiomyoma.Compared with MWA,RFA with lower adverse reactions during operation and postoperation.

Objectives To investigate the incidence of brain injuri in premature infants in ten hospitals of seven large cities in China sponsored by the Subspecialty Group of Neonatology of Pediatric Society, China Medical Association. Methods All premature infants with gestational age less than 37 weeks in ten hospitals were given routine cranial ultrasound within three days of birth, and then repeated every 3-7 days till the discharge from the hospital during January 2005 to August 2006. Results Incidence of intraventricular hemorrhage (IVH) and severe IVH were 10.8% (406/3 768) and 2.4% (92/3 768) with 22.6% (92/406) for grade 1, 54.7% (222/406) for grade 2, 17.2% (70/406) for grade 3 and 5.4% (22/406) for grade 4 in nine hospitals; incidence of periventricular leukomalacia (PVL) and cystic PVL were 2.3% (112/4 933) and 0.3% (16/4 933) with 85.7% (96/112) for grade 1, 12.5% (14/112) for grade 2, and 1.8% (2/112) for grade 3 including all ten hospitals, respectively. Risk factors associated with increased severity of IVH were vaginal delivery (OR = 1.874, 95% CI = 1.172 - 2.997, P < 0.01), perinatal asphyxia (OR = 1.598, 95% CI = 1.077 - 2.372, P < 0.05), mechanical ventilation (OR = 3.988, 95% CI= 2.448 -6.948, P< 0.01), and amniotic fluid contamination (OR = 2.192, 95% CI = 1.054 - 4.544, P< 0.05). Risk factors that might result in the development of cystic PVL were vaginal delivery (OR = 1.400, 95% CI = 1.186 - 1.652, P < 0.001) and mechanical ventilation (OR = 3.000, 95% CI = 1.015 - 8.864, P < 0.05). Conclusions These data reflect basically the prevalence of brain injuriy in premature infants in major cities of China. However, more than 60% of population lives in the rural area, further multicenter investigation including the rural area is expected to be undertaken in future.

Objective: Thought-action fusion (TAF), one of the most-studied dysfunctional beliefs in obsessive-compulsive disorder, represents an individual’s belief that his/her thoughts directly influence events. TAF belief types are divided into personal thoughts relating to positive (positive TAF) and negative outcomes (negative TAF). However, the neural mechanisms underlying both aspects of the TAF response remain elusive. Methods: This functional magnetic resonance imaging study aimed to investigate the neural circuits related to positive and negative TAF and their relationships with psychological measures. Thirty-one healthy male volunteers participated in a modified TAF task wherein they were asked to read the name of a close person embedded in positive statements (PS) or negative statements (NS). Results: Conjunction analysis revealed activation of the fusiform and lingual gyri, midcingulate and superior medial frontal gyri, inferior orbitofrontal gyrus, and temporoparietal junction. The NS ＞ PS comparison showed additional activation in the precuneus and medial prefrontal cortex, superior frontal gyrus, insula, globus pallidus, thalamus, and midbrain. Precuneus activity was associated with the TAF score among these areas. Moreover, activity in the inferior orbitofrontal gyrus, insula, superior, middle and medial frontal gyri, globus pallidus, inferior parietal lobule, and precuneus was associated with dimensional obsessive-compulsive scores. In contrast, the PS ＞ NS comparison revealed no significant activation. Conclusion These results suggest that negative TAF, relative to positive TAF, recruits additional regions for self-referential processing, salience, and habitual responding, which may contribute to the activation of the belief that a negative thought increases the probability of that negative outcome.

Conjugate upward and downward gaze palsy related to unilateral midbrain infarction is a rare neurological symptom, as there were few reported cases worldwide. Here, we report a case of 55-year-old male patient presenting with conjugate vertical gaze palsy.
