Objective To analyze the therapy and prognosis of palindromic ovarian carcinoma. Methods The clinical data of 40 cases of palindromic ovarian carcinoma were reviewed retrospectively. Results After the first surgery, the mean recurrent time of the patients with remained tumors smaller than 2 0 cm was (37 26?11 79) months, and that of the patients with remained tumors larger than 2 0 cm was (7 88?1 49) months. There was a significnat difference in the mean recurrent time between the two groups of the patients with different size of remained tumors(P0 05). Conclusion The recurrence of ovarian cancer was related to the size of remained tumor. Secondary operation plus chemotherapy could improve the short-term survival rate of the patients with palindromic ovarian carcinoma.

Objective To explore the correlations of expressions of gastric mucosa water channel aquaporin AQP3 and AQP4 and different gastritis types. Methods The gastric mucosa was mounted under gastroscope. The types of gastric mucosa pathology and activity were tested by the common pathohistology. The expressions of AQP3 and AQP4 were determined by immunohistology. Results The expressions of AQP3 and AQP4 of chronic superficial gastritis were significantly higher than those in the non-gastritis group and chronic atrophic gastritis group (P < 0.01), especially in the activity period of chronic superficial gastritis. The expressions of AQP3 and AQP4 of chronic atrophic gastritis group were reduced when compared to those in the non-gastritis group, in spite of no statistical differences between them. While compared to the non-gastritis group , the expression of AQP3 of chronic atrophic gastritis group during the active stage was remarkably decreased (P < 0.05). Conclusion The expressions of AQP3 and AQP4 of gastric mucosa in chronic gastritis in various pathological types are different. AQP3 and AQP4 may be the targeted point , which could be used for the differential diagnosis and treatment of chronic gastritis of different pathological types.

Objective To evaluate puncture technique in thoracic endovascular aortic repair with abdominal aortic aneurysm and assess the feasibility and safety of using a pre-close technique for puncture and closure of femoral access sites. Methods From May 2010 to August 2013, the pre-close technique which involved two 6 F per-close ProGlide devices deployed in the femoral artery before upsizing to a 18-25 F sheath and one or two deployed before upsizing to a 14-16 F sheath were applied to 42 patients with abdominal aortic aneurysm (group A). Forty-seven patients using surgical femoral cutdown from December 2006 to April 2010 were enrolled into group B. The rate of technical success, time from procedure to the aortic delivery, operation time, low limb braking time, local complication, time from procedure to discharge, local vascular diameter after 3 months was evaluated and compared between two groups. Results There was no significant difference in endograft external diameter between two groups ( P>0.05). The rate of technical success was 97.62%(41/42) in group A and 95.74%(45/47) in group B, and there had no significant difference (P>0.05). Time from procedure to the aortic delivery, operation time and time from procedure to discharge in group A were significantly shorter than those in group B: (21.79 ± 5.79) min vs. (41.37 ± 11.79) min, (127.66±37.83) min vs. (157.84±42.71) min, (6.59±1.89) d vs. (9.14±2.57) d, P<0.05. The incidence rate of local complications, low limb braking time, and local vascular diameter after 3 months had no significant difference between two groups:7.14%(3/42) vs. 8.51%(4/47), (8.51± 1.83) h vs. (8.38±1.79) h, (1.05 ±0.36) mm vs. (0.98 ±0.31) mm, P>0.05. Conclusion The puncture technique with per-close ProGlide is safe and effective in percutaneous endovascular aortic repair which can be adopted as an alternative technique of surgical femoral cutdown approach in patients with abdominal aortic aneurysm.

OBJECTIVETo determine the effect of AQP1 gene on facial nerve edema following injury through investigation of the relationship between the expression of AQP1 gene and Schwann cells swelling.

METHODSThe AQP1 expression in Schwann cells of mouse facial nerve tissues was detected by immunofluorescent staining. The transgenic protocol by lentivirus transduction was used to specifically upregulate AQP1 expression in Schwann cells. Lenti-AQP1 and CTRL (empty vector) transduced cells were observed during gene overexpression every 24 h for 6 days by using phase contrast microscopy. Cell volume of CTRL and Lenti-AQP1 treated cells was measured daily from the day of treatment, through day 6.

RESULTSSchwann cell primary cultures maintained a high level of AQP1 water channels, representing an ideal cell model to study the role of AQP1 in the facial nerve. The expression of AQP1 mRNA and protein in Schwann cells infected with the Lenti-AQP1 was increased significantly compared with CTRL lentivirus (P < 0.05). Lenti-AQP1 caused cell swelling in cultured Schwann cells, as validated by cell volume determinations (P < 0.01).

CONCLUSIONSAQP1 is an important factor responsible for the fast water transport of cultured Schwann cells. It plays an important role in facial nerve edema.

Objective To study the long-term neurodevelopment in term neonates with hyperbilirubinemia and explore the predictive value of cerebrospinal fluid neuron specific enolase (CSF-NSE) on long-term neurodevelopment outcome.Methods A mental and psychomotor scale for 0-4 years old was performed to evaluate the intelligence development of 39 neonates with hyperbilirubinemia and 39 randomly selected healthy controls when they were at 3 to 24 months old. The former were tested for the level of CSF-NSE in jaundice climax.Results There was significant difference between 2 groups in total development quotient (DQ) tested at 3 month and 24 month old (P=0, 0.047). It was shown that the DQ scores for fine activity and social behavior were significantly lower in the study group than those in the control group (Pa=0). Furthermore, within the hyperbilirubinemia group, CSF-NSE was significantly associated with DQ of 3 month and 24 month old, while there was not association with TSB. The correlation coefficients were -0.46(P=0.04) and -0.32(P=0.047),respectively.Conclusions Hyperbilirubinemia may influence long-term neurodevelopment of term infants and CSF-NSE can predict this outcome.

Objective To investigate the correlations between the time of thoracic endovascular aortic repair (TEVAR) and prognosis in patients with type B acute aortic dissection (AADB). Methods The clinical data of 156 AADB patients with TEVAR was retrospectively analyzed and divided into 3 groups according to the time from onset of symptom to TEVAR:less than seven days was deifned as group 1 (G1, n=87), seven days to fourteen days group 2 (G2, n=48);more than fourteen days was group 3 (G3, n=21). The status of aortic reconstruction at three months TEVAR, in-hospital mortalities, mean hospital expense and length of stay were compared among three groups. Results Before TEVAR, there was no signiifcant differences in the ratio of smallest true lumen diameter and largest false lumen diameter amony the three groups (0.47±0.33, 0.42±0.18, 0.47±0.27, respectively, P>0.05). At three months after TEVAR, the ratio of largest true lumen diameter and largest false lumen diameter among the three groups was signiifcantly greater in group 1 (1.76±0.51) than group 2(1.42±0.30) and group 3(1.34±0.34, P < 0.05), when there was no signiifcant difference between the later two groups. Complete aortic reconstruction (8 from group 1 and 4 from group 2) was achieved in 12 patients at 3 months after TAVAR. Eight patients died during hospitalization, 5 from visceral ischemic, 2 from proximal aortic dissection, one patient from sudden death. Compared with G3, the hospital expense of group 1 and group 2 was cut down about ￥20000. Length of stay was signiifcant greater in group 3 than in group 1 and group 2 (P<0.05). Conclusions Early TEVAR for AADB was safe and beneifcial for aortic reconstruct and reducing the hospital expense and length of stay.
