Ojective To investigate therapeutic results of conservative operation with laparoscopy for all kinds of patients with tube pregnancy. Methods 62 patients with tube pregnancy were performed the conservative surgery, fenestration on the position of tube pregnancy or take out embryos from the tube crevice combined with injection of MTX under laparoscopy. Results all of 61 patients' tube were retained successfully. no complications occurred, urine HCG recovered to normal levels two weeks after operation. Only one patient continue to pregnancy and completely recovered after intramuscular injection MTX. 18 patients were carried out HSG 1~4 months after operations. 15 patients' tube among them were unobstructed. Opening rate was 88.3%. Within postopeative four years, 12 patients were repregnant. Pregnancy rate was 66.7%. Conclusions Tube pregnancy conservative treatments under laparoscopy not only is safe and minimal invasion, but also had less complications, therefore it is a more suitable method for retaining the fertile females' tubes.

Objective To investigate the methods and techniques of simplified binding pancreaticojejunostomy for patients with periampullary malignant tumor after radical pancreatoduodenectomy (RPD). Methods From March 2005 to May 2010, 323 patients with periampullary malignant tumor received RPD at the Tongji Hospital of Huazhong University of Science and Technology, and their clinical data were retrospectively analyzed.Simplified binding pancreaticojejunostomy was applied after RPD: the distal end of pancreas was freed for 3-4 cm;a No. 6 or No. 8 silicone urinary catheter was inserted into the pancreatic duct for 4-5 cm, and the remaining urinary catheter (6-8 cm) out of the pancreatic duct was sutured to the pancreatic stump with absorbable sutures.The cutting end of the jejunum (2-3 cm) was everted, and the everted mucosa of the jejunum ( 1 cm) was injured by electrocautery, then the everted jejunum was reverted to its normal position. The cutting end of the mesentery of jejunum and its opposite side, as well as the mid-point of these two parts were sutured symmetrically with the lower and upper edges of the pancreas, and with the capsule of pancreas between them. The everted jejunum was wrapped over the pancreatic stump and sutured it to the pancreas for fixation. The cutting end of the jejunum was bound to the pancreatic stump with 1-0 absorbable suture after confirming the jejunum was completely invaginated into the pancreas. The alimentary tract was reconstructed by using Child's method. Results Simplified binding pancreaticojejunostomy was successfully completed in all patients, Pancreatic fistula was detected in one patient who was complicated with anastomotic bleeding on the third day after secondary laparotomy. The patient was discharged with catheter and spontaneously recovered one month later. Pancreatic fistula was also detected in two patients with distal bile duct carcinoma and two patients with carcinoma in the uncinate process of pancreas at postoperative day 3, 6, 8 and 11, and they were cured by expectant treatment. The incidence of pancreatic fistula was 1.5% (5/323). Conclusion Simplified binding pancreaticojejunostomy is simple, safe and feasible, and it can significantly reduce the incidence of pancreatic fistula.

OBJECTIVE:To establish the method for simultaneous determination of 9 components in Huichun yuzi granules. METHODS:LC-MS/MS method was adopted. The determination was performed on Shim-pack XR-ODS C18column with column temperature of 30 ℃. The sample size was 5 μL,and ion source as electrospray ion source;MRM mode was adopted. The acetonitrile-water was used as mobile phase for ferulic acid,rutin,paeonol,icariin and schisandrin(gradient elution);positive ion mode monitoring was conducted. The methanol-0.1% fomic acid water was used as mobile phase for naringin,verbascoside, amygdalin and protocatechuic acid(gradient elution);negative ion mode monitoring was conducted. RESULTS:The linear ranges of ferulic acid,rutin,paeonol,icariin,schisandrin,naringin,verbascoside,amygdalin and protocatechuic acid were 0.499 5-500, 25-1 000,0.245 9-250,5.185 1-1 000,0.981 9-1 000,0.248 1-125,2.510 4-250,10-2 500,4.999 7-1 000 ng/mL(r≥0.997 8), respectively.

The hemodynamics of children with congenital heart disease (CHD) often changes during the perioperative period. Unfortunately, the evaluation of cardiac function in children with CHD is mainly focused on the left ventricle. With the further understanding of cardiac hemodynamics, the monitoring of RV function has gradually become an important part of cardiac intensive care department. We totally searched five databases including Pubmed, Embase, Cochrane, Wanfang Med, as well as China National Knowledge Infrastructure (CNKI) and reviewed the clinical research progress of the application of TAPSE in the evaluation of RV systolic function in children with CHD to provide a theoretical basic for the monitoring of RV function before and after operation in children with CHD.

Myocardial ischemia (MI) causes somatic referred pain and sympathetic hyperactivity, and the role of sensory inputs from referred areas in cardiac function and sympathetic hyperactivity remain unclear. Here, in a rat model, we showed that MI not only led to referred mechanical hypersensitivity on the forelimbs and upper back, but also elicited sympathetic sprouting in the skin of the referred area and C8-T6 dorsal root ganglia, and increased cardiac sympathetic tone, indicating sympathetic-sensory coupling. Moreover, intensifying referred hyperalgesic inputs with noxious mechanical, thermal, and electro-stimulation (ES) of the forearm augmented sympathetic hyperactivity and regulated cardiac function, whereas deafferentation of the left brachial plexus diminished sympathoexcitation. Intradermal injection of the α2 adrenoceptor (α2AR) antagonist yohimbine and agonist dexmedetomidine in the forearm attenuated the cardiac adjustment by ES. Overall, these findings suggest that sensory inputs from the referred pain area contribute to cardiac functional adjustment via peripheral α2AR-mediated sympathetic-sensory coupling.
