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 observe the changes of cardiac rhythms in a swine model of adult asphyxia! cardiac arrest. Method Sixteen Pigs were aphyxiated by endotracheal tube clamping until 8 min after loss of aortic pulsations. Resuscitation was then provided and swinds were assigned to received 0.045 mg/kg epinephrine intravenously after 3 min of basic life support. The animals with restoration of spontaneous circulation within 20 min from CPR were defined as successfully resuscitated, while the rest were identified as unresuscitation. Electrocardiogram ( EGG) were monitored from the start of asphyxia to the start of the CPR. Results When loss of pulsations occurred, 2 of 16 animals had ventricular fibrillation; 10 pigs exhibited pulseless electrical activity, and 4 pigs had asystole. During the 8 min after the loss of aortic pulsations, pulseless electrical activity converted to VF in 7 pigs. Immidiatedly prior to resuscitation, VF occurred in 9 pigs, asystole in 4 pigs, and PEA in 3 pigs. Conclusions Most of animals in this swine model of asphyxial cardiac arrest presented PEA, but most of them converted to VF especially late in the asphyxial process.

BACKGROUND:Titanium artificial cervical disc has good biocompatibility, but titanium al oy is shown to have poor biological activity, low bonding strength, easy release of metal ions under physiological conditions.
OBJECTIVE:To observe the effects of different coating for the titanium plate of domestic cervical artificial disc on adhesion and differentiation ability of rat bone marrow mesenchymal stem cel s.
METHODS:Passage 3 bone marrow mesenchymal stem cel s from Wistar rats were seeded into 24-wel titanium plates with hydroxyapatite coating, titanium powder+hydroxyapatite coating and bare titanium plate. Cel culture was terminated after 24 and 48 hours, and the cel growth was observed under scanning electron microscope. After 24 hours of inoculation, osteogenic inducer was added;then, cel supernatant was col ected at 3, 5, 7 days after cel lysis and centrifugation to detect the activity of alkaline phosphatase.
RESULTS AND CONCLUSION:After composite culture with titanium plates with hydroxyapatite coating or
titanium powder+hydroxyapatite coating, cultured cel s were in polygonal shape, and pseudopodia were extended into the micropores that were adhered closely to the material surface. Cel s cultured with bare titanium plates had poor differentiation and adhesion rate. With time, the expression of alkaline phosphatase was increased in each group, especial y in the groups of titanium plates with hydroxyapatite coating and titanium powder+hydroxyapatite coating (P<0.05). These findings indicate that titanium plates with hydroxyapatite coating or titanium powder+hydroxyapatite coating can promote adhesion and differentiation of rat bone marrow mesenchymal stem cel s.

Clinical features of 1 case of retroperitoneal parasitic fetus (PF) were retrospectively analyzed and Chinese literatures were reviewed. PF in China has 4 clinical features: 1) The incidence was extremely low and it was more common in infants and children. 2) The parasitic parts showed centrality. 3) The retroperitoneum and abdominal cavity were the most common parasite locations. 4) There was no gender difference in the incidence. Retroperitoneal PF should be distinguished from various benign and malignant abdominal tumors. Imaging was the optimal option for PF diagnosis and the axis bone system was its typical manifestation. Complete excision was the optimal treatment. Thick and large nutrient vessels may be found at where the placenta was attached, and should be ligated carefully. The outcome of this case was good because PF was completely excised.
