RESUMO
Objective:To explore the application value of three-dimensional visualization technology in the analysis of anatomic variation of peripancreatic vessels in patients with pancreatic space occupation.Methods:A total of 98 cases in Yijishan Hospital of Wannan Medical College, the First Affiliated Hospital of University of Science and Technology of China, the First Affiliated Hospital of Anhui Medical University, the Second Affiliated Hospital of Anhui Medical University, the First Affiliated Hospital of Bengbu Medical College, Fuyang People's Hospital from June 2018 to December 2019 were retrospectively analyzed. Of 94 patients were enrolled, including 56 males and 38 females, aged (61.2±7.2) years. Abdominal organs and blood vessels were reconstructed by 3D visualization technology, and anatomic variation of peripancreatic vessels was analyzed, including abdominal trunk, hepatic artery system, portal vein system and dorsal pancreatic artery.Results:The three-dimensional reconstruction rate of celiac trunk vessels was 100.0% (94/94). The 60 cases of abnormal celiac trunk were as follows: liver and spleen trunk in 5 cases (5.3%), stomach and spleen trunk in 1 case (1.1%), liver, stomach and spleen mesentery trunk in 3 cases (3.2%), liver, stomach and spleen mesentery trunk in 17 cases (18.1%), celiac trunk with one or more inferior phrenic arteries in 34 cases (36.2%). There were 69 cases (73.4%) of Michels type Ⅰ, 2 cases (2.1%) of Michels type Ⅲ, 1 case (1.1%) of Michels Ⅴ, 2 cases (2.1%) of Ⅷ, and 1 case (1.1%) of type Ⅸ of hepatic artery system. There were 17 cases (18.1%) of accessory left hepatic artery from celiac trunk which did not belong to Michels classification. Left accessory hepatic artery originated from left gastric artery and left hepatic artery originated from superior mesenteric artery in 1 case (1.1%), right accessory hepatic artery originated from celiac trunk combined with proper hepatic artery and right anterior hepatic artery combined with gastroduodenal artery originated from right posterior hepatic artery in 1 case (1.1%). Abnormal walking of dorsal pancreatic artery in 3 cases. The inferior mesenteric vein flowed into the superior mesenteric vein in 38 cases (40.4%), and the inferior mesenteric vein flowed into the splenic vein and superior mesenteric vein in 4 cases (4.3%).Conclusion:Three-dimensional visualization technique is helpful to determine the variation of peripancreatic vessels, and has certain significance for accurate preoperative evaluation and surgical guidance of patients with pancreatic space occupation.
RESUMO
OBJECTIVE@#To explore the effect and clinical significance of serum S100β and NSE on moderate and severe obstructive sleep apnea syndrome (OSAHS) after the continuous positive airway pressure (CPAP).@*METHOD@#A total of 60 cases with obstructive sleep apnea were choosed with PSG in our hospital in June 2009 to June 2009. According to apnea hypoventilation index and at night the lowest oxygen saturation, divided into severe group (n=60) and moderate group (n=60), selecting 60 cases of healthy physical examination for a control over the same period. According to the length of the course of the disease in patients with each group can be divided into 10 years group, severe and moderate groups were recruited to undergo an CPAP treatment,both before and after treatment for 3 months, the lowest oxygen saturation, average blood oxygen saturation and apnea hypoventilation index were determined in moderate and severe groups with PSG, at the same time, serum S100β and NSE were determined with immune enzyme-linked adsorption testing before and after patients in different course of treatment and control group.@*RESULT@#Compared with pretherapy of severe and moderate groups, the lowest oxygen saturation, average blood oxygen saturation and apnea hypoventilation index were ower after treatment (P 10 years before and after treatment in patients with serum according to beta and NSE levels higher than 5-10 patients, 5-10 patients before and after treatment according to beta and NSE serum levels higher than 0. 05), the relation between two groups according to beta, NSE serum are positively correlated with AHI (P < 0. 01).@*CONCLUTION@#CPAP significantly reduced serum S100β and NSE levels in patients with OSAHS, both may be important index which evaluated nervous system protection of CPAP in patients with OSAHS.

Objective To investigate the clinical features, pathological characteristics and prognostic factors of the ma-lignant ovarian germ cell tumor. Methods There was a retrospective analysis about 31 patients of malignant ovarian germ cell tumor from Jan 2006 to Dec 2011,while clinic and pathological factors were analyzed,and the related litera-ture was prognostic analyzed. Results Nine cases were ovarian teratoma with malignant change in 31 patients. 7 cases were ovarian immature teratoma, 6 cases were ovarian dysgerminoma, 5 cases were yolk sac tumor, 3 cases were em-bryonal carcinoma, 1 patient was ovarian mixed yolk sac tumor and embryonal carcinoma. Multivariate survival analysis showed that operation pathological staging and pathological types were independent prognostic factors affecting overall survival rate for patients (P=0.018 and P=0.021). A variety of different pathological types of malignant ovarian germ cell tumor survival rate, the difference was statistically significant (P=0.049). Conclusion Operation and pathology of malignant ovarian germ cell tumor staging more late, the survival rate of the patients is low. Prognosis of ovarian malig-nant germ cell tumors of different pathological types is different.
RESUMO
Objective To observe the changes of learning function and neuron-specific enolase (NSE)protein of both brian and serum in rats after intermittent hypoxia,and explore the relation between NSE protein and learning and memory function.Methods Male Wistar adult rats(n=48)were randomly divided into control group (UC group) and 7.5% chronic intermittent hypoxia group (7.5%CIH group).7.5% chronic intermittent hypoxia model in rats were simalated by using the self-made cabin of intermittent hypoxia.At the 2nd,4th,6th,and 8th week respectively,learning and memory function in rat was tested by Morris water maze in two groups.The level of NSE protein in hippocampal CA1 region was detected by immunohistochemical method,and was detected in serum of rats by using enzyme-linked immunosorbent adsorption method.Results Compared with the control group,7.5% CIH group at the 2nd,4th,6th,and 8th week in rats from the second week of the escape latency time was 44.13± 2.84) s,(50.35 ± 1.96) s,(57.47 ± 1.66) s,(62.85 ± 1.80) s,and across the target quadrant time was 48.81 ± 2.09) s,(42.04± 1.84) s,(36.82± 2.07) s,(31.81 ± 1.68) s.From the first two weeks,the longer the hypoxia time prolonged,the longer the rat's escapedlatency (P<0.05) and the shorter the rats acrossed the target quadrant (P <0.05).7.5% CIH group of hippocampal CA1 neurons NSE protein at the 2nd,4th,6th,and 8th week was (9.69±1.37),17.10± 1.87),(24.79± 3.51),(34.16±5.35),respectively,and serum NSE protein at the 2nd,4th,6th,and 8th week respectively was (6.03±0.91) μg/L,(11.04± 1.89) μg/L,(16.39± 1.00) μg/L,(24.22±3.73) μg/L,both of which were more than the control group.The difference was statistically significant (P<0.05).7.5% CIH group of hippocampal CA1 neurons and serum NSE protein expression were significant time differences,and gradually increased over time.The difference was statistically significant (P<0.05).Positive NSE protein expression in hippocampal CA1 region relative NSE and serum protein expression values were positively correlated (r=0.94,P <0.01).But in control group NSE protein expression did not exist time difference (P>0.05).Conclusion Intermittent hypoxia can cause NSE levels significant increase in serum and brain tissue,and the dynamic changes of them can reflect severity of learning and memory impairement in rat.
RESUMO
Objective To study the clinical characteristics and to summarize our experience in the diagnosis and treatment of ectopic splenic autotransplantation (ESAP) many years after splenic rupture and splenectomy.Methods The clinical data of 15 patients with ESAP who were treated in the People's Hospital of Zhengzhou from January 1998 to January 2013 were retrospectively analyzed.Results Of the 15 patients,2 patients presented with intestinal obstruction due to the ectopic splenic tissues and required partial resection of small intestine.In 5 patients,the ectopic splenic tissues were in the greater omentum which required resection of part or the whole of the greater omentum.In 4 patients,the ectopic splenic tissues were in the mesentery which required partial or total resection of the tissues.The ectopic tissues were in the pelvis in 3 patients and resection of the left fallopian tube was carried out in 2 patients and resection of the pelvic tissues in 1 patient.In 1 patient the diagnosis was made under laparoscopic biopsy,thus avoiding open surgery.Three patients had multiple implanted sites for these ectopic splenic tissues.Conclusions ESAP is an uncommon disease and it has no clinical characteristics.It is easy to confuse the condition with metastatic deposits.A diagnosis could be made only by combining the history with magnetic resonance imaging,or 99mTc study of red blood cells,or laparoscopic exploration and biopsy.
