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.

While paying attention to the psychological problems of patients, medical staff should also include caregivers in the object category of psychological care and actively explore effective nursing measures to promote the physical and mental health of caregivers.

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.

Objective:To evaluate the residual risk (RR) of transfusion transmitted HIV (TT-HIV) after the implementation of nucleic acid amplification test (NAT) in blood screening test among blood centers in China.Methods:The data of blood donors and HIV infection markers from 2017 to 2020 were collected from 28 blood centers via the Platform of Comparison of blood establishments Practice in Chinese Mainland. The new infection rate/window period mathematical model was used for two types of blood screening strategies, namely, two rounds ELISA plus individual NAT take turn with pooling NAT (2ELISA+ ID-NAT/MP-NAT) and two ELISA plus one round pooling NAT (2ELISA+ MP-NAT), and the RR of HIV infection was estimated also based on first donors (FDs) and repeated donors (RDs) in different blood donation years. T-test analyses were conducted for comparing TT HIV RR among FDs and RDs in different blood donation years with two blood screening strategies, and the variation trend of RR in HIV test was observed.Results:From 2017 to 2020, the RR of FDs in 2ELISA+ ID-NAT/MP-NAT blood screening strategy was 2.869/10 6 person-year, 3.795/10 6 persons-year, 3.879/10 6 person-year, and 2.890/10 6 person-year respectively. The RR of RDs was 1.797/10 6 person-year, 1.502/10 6 person-year, 1.857/10 6 person-year, and 1.483/10 6 person-year respectively. Significant difference exists between RR of FDs and RDs, with F=9.898 and p<0.05. In 2ELISA+ MP-NAT strategy, the RR of FDs was 3.508/10 6 person-year, 1.868/10 6 person-year, 2.204/10 6 person-year, and 1.765/10 6 person-year respectively. The RR of RDs was 0.948/10 6 person-year, 0.926/10 6 person-year, 0.748/10 6 person-year, and 0.682/10 6 person-year respectively. Statistical difference existed between RR of FDs and RDs, with F=17.126 and P<0.05. There was no significant difference between the RR of FDs in these two strategies with F=3.493 and P>0.05, while there was a difference between the RR of RDs in these two strategies with F=24.516 and P<0.05, and a difference between the RR of total donors (TDs) in these two strategies F=20.216 and P<0.05. Conclusions:The RR of TT HIV significantly decreased after the introduction of NAT into blood test among blood centers in China. There were some differences in the RR of HIV testing among different blood screening strategies. There could be significant differences in the RR of HIV testing among different groups of blood donors. Compared with FDs, RDs is the low risk group for HIV.

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.
