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.

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    To summarize the results of surgical treatment for 79 patients with coarctation of the aorta (CoA) combined with complex anomalies (CA) in recent years. Methods    The data from 79 patients with CoA combined with CA admitted to Guangzhou Women and Children's Medical Center between January 19, 2010 and September 7, 2017 were collected and analyzed. There were 52 males and 27 females. The median age was 71 days, and the median weight was 4.3 kg. There were 26 patients combined with tracheostenosis and 7 patients with preoperative tracheal intubation. Extended end-to-side anastomosis was used to correct the CoA, and the associated cardiac abnormalities were treated simultaneously by an incision through median sternotomy. All operations were performed by the same group of surgeons. Results    The median deep hypothermic circulatory arrest was 18 (13-28) minutes, the median aorta cross-clamp time was 62 (15-199) minutes, the median cardiopulmonary bypass time was 145 (71-674) minutes, the median ventilation time was 72 (9-960) hours, the median length of ICU stay was 144 (12-1 944) hours, and the median length of hospital stay was 24 (2-93) days. Early death occurred in 9 patients and late death occurred in 5 patients. Reoperation occurred in 28 patients and recoarctation developed in 10 patients. After operation, transcoarctation gradient was reduced, and the transcutaneous oxygen saturation, C-reactive protein (CRP), lactate and creatinine were increased. Compared to the survival group, both preoperative and postoperative transcutaneous oxygen saturation were worse and the postoperative levels of plasma brain natriuretic peptide (BNP) and CRP were higher in the death group. Conclusion    Correcting the CoA and the associated CA simultaneously with extended end-to-side anastomosis by an incision through median sternotomy is effective and safe, and the outcomes of immediate and medial-term are satisfactory. Improving oxygenation and limiting elevation of BNP and CRP levels may reduce the death rate.
