Objective To evaluate the laparoscopy in the diagnosis and treatment for acute abdominal emergency. Methods A retrospective analysis was conducted on clinical data of 35 patients with an acute abdomen of unknown causes diagnosed and treated under laparoscope from December 1999 to April 2003 in this hospital. Results Diagnosis was confirmed by laparoscopy in all the 35 cases. Laparoscopic operation was successfully completed in 28 cases, whereas a conversion to open surgery was required in 7 cases, in which the site of incision was under the guidance of laparoscopic observations. No surgery-related deaths or wound-related complications occurred. The mean operative time was 48 min (range, 30~72 min), and the mean hospital stay was 5.8 days (range, 3~9 days). Conclusions Laparoscopy is not only a safe and accurate diagnostic method, but also a good procedure for treatment.

Background and purpose:RASSF10 acts as a kind of tumor suppressor in various tumor tissues, but researches in cardiac adenocarcinoma has not been reported. This study aimed to detect the methylation status and expression ofRas-association domain family 10 (RASSF10) in gastric cardia adenocarcinoma (GCA), and explore its role in occurrence and development of GCA.Methods:Methylation speciifc polymerase chain reaction (MSP), reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry method were respectively used to detect methylation status, mRNA expression and protein expression ofRASSF10 in 81 GCA tissues and corresponding normal tissues.Results:The promoter methylation frequency ofRASSF10 in GCA tissues (64.20%, 52/81) was signiifcantly higher than that in corresponding normal tissues (20.99%, 17/81,P<0.05), and was closely correlated with TNM stages, differential degree and lymph node metastasis (P<0.05). RASSF10 mRNA expression in GCA tissues (0.57±0.05) was significantly lower than that in corresponding normal tissues (0.78±0.02,P<0.05), and was closely correlated with TNM stages and lymph node metastasis (P<0.05). Protein expression of RASSF10 in GCA tissues (31.10%, 26/81) was signiifcantly lower than that in corresponding normal tissues (71.60%, 58/81,P<0.05), and was closely correlated with TNM stages, differential degree and lymph node metastasis (P<0.05). The promoter methylation frequency ofRASSF10 in GCA tissues was inversely related to its protein expression.Conclusion:Inactivation of RASSF10 caused by aberrantmethylation in the promoter region may be closely correlated with the GCA tumorgenesis.

Objective To improve detectable rate of gastric schwannoma by endoscopic ultrasonography (EUS). Method Clinical data and endoscopic ultrasonography (EUS) imaging features of 4 cases were retrospectively ana-lyzed which diagnosed as gastric schwannoma pathologically and immunohistochemically while diagnosed as gastric stromal tumor by EUS from May 2008 to June 2015 and reviewed the literature. Results 4 cases of gastric schwan-nomas are female and benign, all 4 lesions are solitary, 3 in gastric body, and 1 in fundus by endoscopic. By EUS, all lesions are originated from muscularis propria, hypoechoic change, even echoes and clear board without calcifica-tion or cystic changes. 2 cases have halo artifacts around the lesion. Literature review found that gastric schwannoma tended to occur in female, halo artifacts could be the feature of gastric schwannoma, calcification or cystic changes were rare in gastric schwannoma which were common in gastric stromal tumors. Conclusion It was difficult to distin-guish gastric schwannoma and gastric stromal tumors that originated from muscularis propria by EUS. For female patients with lesions originated from muscularis propria, originated from muscularis propria and occurred in gastric body, it was necessary to observe lesions whether there was being calcification or cystic and halo artifacts. Integrated all these performance, we should be in consideration of gastric stromal tumors, meanwhile, excluding the possibility of gastric schwannoma.

Objective To investigate the characteristics of attention networks impairment in benign epilepsy children with centrotemporal spikes.Methods The attention network test was performed in benign epilepsy children with centrotemporal spikes (n =75) and normal controls (n =75) on the efficiency of three anatomically defined attention networks:alerting,orienting,and execrtive control.Results The correct rate of attention network test was significantly lower in benign epilepsy children with centrotemporal spikes (95.77％ ± 5.63％) than that in normal controls (98.55％ ± 1.80％ ; t =4.063,P ＜ 0.05).The total average response time was significantly longer in benign epilepsy children with centrotemporal spikes ((946.87 ± 199.82) ms) than that in normal controls ((729.00 ± 146.75) ms ; t =-7.611,P ＜ 0.05).The orienting network effect (29 (12,56)ms) was lower in benign epilepsy children with centrotemporal spikes than in normal controls (51 (21,78) ms; Z =-2.771,P =0.006).The executive control network effect was higher in benign epilepsy children with centrotemporal spikes (80 (50,105) ms) than in normal controls (57 (25,88) ms; Z =-2.146,P =0.032).However,the difference in alerting network effects between the two groups was not statistically significant (P ＞ 0.05).Logistic regression analysis showed that the age on onset of the disease was an independent risk factor for the correct rate of attention network test and the total average response time (OR =1.830,95％ CI 1.193-2.807,P =0.006 ; OR =1.635,95％ CI 1.176-2.275,P =0.003).Conclusions The benign epilepsy children with centrotemporal spikes have impairment of attention networks.The age on onset of the disease has a significant impact on the attention of children with rolandic epilepsy.

Background and purpose: As one of the important epigenetic phenomena, DNA methylation plays an important regulatory function for the expression of genes. Study shows that abnormal changes of DNA methy-lation patterns of normal tumor cell genome leads to dysfunction of cancer related gene, and this may be associated with tumor occurrence and development. The study investigated the promoter methylation and expression of caveolin-1 (CAV-1) gene in esophageal squamous cell carcinoma (ESCC), and to elucidate its role in ESCC. Methods:We used MSP approach, RT-PCR, and immunohistochemistry method respectively to examine the methylation status of the 5’CpG island of CAV-1 gene and its expression at mRNA and protein levels in tumors and corresponding normal tissues. Results: CAV-1 mRNA expression in tumor tissues (0.86±0.56) was signiifcantly higher than that in corresponding normal tissues (0.40±0.36, P<0.05). The mRNA expression of CAV-1 was correlated with status of lymphatic metastasis and TNM stage of ESCC patients (P<0.05). The protein expression of CAV-1 in tumor specimens (66.7%, 34/51) was signiifcantly higher than that in corresponding normal tissues (15.7%, 8/51, P<0.01). The protein expression of CAV-1 was signiifcantly associated with lymphatic metastasis of ESCC (P<0.05), however, it was not associated with differen-tiation and TNM stage (P>0.05). The promoter methylation frequency of CAV-1 in tumor specimens was 2.0%(1/51), and the methylation phenomenon has not been found in corresponding normal tissues. The promoter methylation fre-quency of CAV-1 in tumor specimens showed no signiifcant difference compared with the corresponding normal tissues (P>0.05). Conclusion:The mRNA and protein expression of CAV-1 in tumor specimens was signiifcantly higher than that in corresponding normal tissues. Aberrant high expression of CAV-1 has played a certain role in promoting tumori-genesis and lymph node metastasis. The expression both in ESCC and corresponding normal tissues has no correlation with the promoter methylation status.
