Objective To explore the role of the autoantibodies against angiotensinⅡ type 1 receptor (ATR-1) in the pathogenesis of preeclampsia. Methods Forty normotensive and 46 pregnant women with preeclampsia were recruited in this study. Synthesized ATR-1 polypeptide fragment was used as antigens to screen the autoantibodies against ATR-1 by ELISA. The level of angiotensinⅡ was also examined. Results The positive rate of the ATR-1 antibodies and plasma level of angiotensin Ⅱ in patients with preeclampsia [63.0%(29/46) and (92.54?37.22) pmol/L] were significantly higher than those in normotensives [7.5% (3/40) and (25.75?12.33) pmol/L, P

Objective To study the therapeutic value of the endoscopic papillectomy for adenoma in the major duodenal papilla.Methods All 3 1 cases with the major duodenal papilla undergoing endoscopic papillectomy from January 2008 to June 2013 were retrospectively reviewed.The clinical data,endoscopic treatment,complications and follow-up were analysed.Results Endoscopic papillectomy was performed successfully in 29 patients.Post-operative pathology showed adenoma with low-grade dysplasia in 25 cases and high-grade dysplasia in 4 cases.One patient (3. 4%,1/29 )bled during operation;and there was no bleeding after operation. There was no perforation during and after the operation. Seventeen patients (58. 6%,17/29)developed hyperamylasemia and 3 patients(10. 3%,3/29)got mild pancreatitis,which were cured by conservative treatment.During follow-up,2 patients (6. 9%,2/29)with high-grade dysplasia had tumor recurrence after 6 months and 2 years respectively.The 27 other patients had no recurrence during the follow-up period.The shortest follow-up was 1 1 months,the longest was 5 years,with a mean time of 33. 5 ±8. 5 months.Conclusion Endoscopic papillectomy is feasible and safe for early tumors of the major duodenal papilla.Although the postoperative recurrence rate is low,it still needs close follow-up.

Objective To introduce improved program for traction wire production in endoscopic submucosal dis-section assisted by oral traction. Methods A retrospective analysis was performed on 40 patients who received en-doscopy intervention. Through the use of improved traction and normal traction, they were divided into experimental group and control group. Then analyze and compare their clinical data like gender, age, traction line installed perfect time, fixed lesions after hemostatic clip off times, one-time complete resection, enbloc resection rate, bleeding and perforation and other complications and other clinical conditions. Results The improvement time was (53.30 ±12.85) s in experimental group, it was significantly shorter than that in control group (105.00 ± 11.68) s ( = 3.42, <0.05). The experimental group fixed lesions after hemostatic clamp off times were significantly less than that in con-trol group (χ2=2.37, <0.05). Conclusions Using innovative methods, adequate preoperative preparation, the op-erator's tacit understanding of nursing cooperation, close attention to the disease after surgery is the key to achieve the desired results of endoscopic surgery.

ObjectiveTo investigate the characteristics of traumatic spinal cord injury (TSCI) urban inpatients of Tianjin in 2007. MethodsInpatients with TSCI of 8 hospitals in Tianjin in 2007 were reviewed. ResultsThere were 73 patients in total. Mean age was (51.34±14.597) years. Male∶Female was 3.56∶1. Falling, motor vehicle accidents (MVC) were the main causes of TSCI. The cervical spinal cord injuries were predominant. 26% were complete injury and 74% were incomplete. 6 cases were dead. Patients with ASIA grade D recover well. ConclusionFor the TSCI, the ages of patients increases and falling is the main cause.

Objective To evaluate the effects and the safety of peroral endoscopic myotomy (POEM) for achalasia (AC).Methods POEM was performed on 7 AC patients from November 2010 to November 2011.Preoperative dysphagia grade,postoperative complications and short-term and long-term efficacy were recorded.Results POEM was performed successfully on all the 7 patients.The operation time were ranging from 46 to 113 minutes,mean 73 ± 20 minutes.Subcutaneous emphysema and mediastinal emphysema occurred in 2 patients,but cured after treatment.The 1-12 month follow-up showed dysphagia of all the patients was obviously improved.Conclusion POEM is efficient and safe to relieve dysphagia of AC patients.

MarR family transcription regulators are ubiquitous among bacteria and archaea. They extensively control multiple cellular processes and elaborately regulate the expression of genes involved in virulence, stress response and antibiotics at translational level. In Xanthomonas campestris pv. campestris, insertional inactivation of MarR family transcription regulator HpaR (XC2827) resulted in significantly decrease in virulence and increase in the production of the extracellular proteases. Here, we reported that the genome of Xcc 8004 encodes nine MarR family transcription regulators. The MarR family transcription regulators, HpaR (XC2827) and XC0449, were heterologous expressed and purified. In vitro MST and Pull-down assay confirmed the physical interaction between HpaR and XC0449. Phenotypical assay determined that deletion of XC0449 resulted in substantial virulence attenuation. In vitro EMSA, in vivo qRT-PCR and GUS activity assay identified that HpaR and XC0449 coordinately act as the transcriptional activator to regulate the expression of the virulence-associated gene XC0705, and eventually control the bacterial virulence and the production of extracellular proteases.

Objective:
To analysis the risk factors of postoperative bleeding of endoscopic submucosal dissection (ESD) for early gastrointestinal cancer.
Methods:
A retrospective study was performed on the data of 430 patients (449 lesions) with early gastrointestinal cancer undergoing ESD in Fujian Provincial Hospital Digestive Endoscopic Center from June 2008 to February 2015 and in Fujian Provincial Hospital South Branch Digestive Endoscopic Center from May 2015 to April 2018. Patients with postoperative bleeding were compared with those without postoperative bleeding on the basis of general conditions, endoscopic performance, postoperative pathology and so on to analysis the risk factors for postoperative bleeding of ESD.
Results:
Among the 430 cases (449 lesions)of early gastrointestinal cancer undergoing ESD, 16 cases (3.7%) had postoperative bleeding. According to whether the occurrence of postoperative hemorrhage, patients were divided into bleeding group (
