Objective:To evaluate the efficacy of preoperative three-dimensional (3D) image reconstruction combined with intraoperative dynamic ultrasonography (IOUS) in laparoscopic precision hepatectomy for intrahepatic bile duct stones.Methods:The clinical data of 66 patients with intrahepatic bile duct stones undergoing laparoscopic hepatectomy in the First People's Hospital of Fuyang District, Hangzhou from January 2018 to January 2023 were retrospectively analyzed, including 32 males and 34 females, aged (49.6±15.2) years old. Patients were divided into the study group ( n=32), who underwent laparoscopic precision hepatectomy using 3D reconstruction combined with IOUS, and the control group ( n=34), who underwent conventional laparoscopic hepatectomy. Perioperative data including the operation time, intraopera-tive blood loss, total volume of drainage on postoperative day (POD) 3, and the rates of complications were compared between the groups. Serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), liver function indices including total bilirubin (TBil) and alanine aminotransferase (ALT) were monitored preoperatively and on POD 1, 3, 5, and 7. Results:The operation time was shorter in the study group [(178±17) min vs. (189±18) min, t=2.55, P=0.010]. The intraoperative blood loss was reduced in the study group [(218±19) ml vs. (395±21) ml, P<0.001]. The incidence of total volume of drainage >300 ml on POD 3 were comparable between the groups [9.4%(3/32) vs. 14.7%(5/34), P=0.507]. There were no significant differences in preoperative serum level of TBil, ALT, CRP and IL-6 between the groups (all P>0.05). Compared to the control group, serum levels of TBil, ALT and CRP in the study group were decreased on POD 1, 3, 5 and 7, and IL-6 was decreased on POD 1 and 3 (all P<0.05). The occurrences of postoperative bile leakage [9.4% (3/32) vs. 29.4% (10/34)] and liver cutting surface fluid accumulation [12.5% (4/32) vs. 35.3% (12/34)] and the rate of stone retention [3.0% (1/32) vs. 20.6% (7/34)] were lower in the study group (all P<0.05). Conclusion:Preoperative 3D image reconstruction combined with IOUS in laparoscopic precision hepatectomy for intrahepatic bile duct stones could reduce intra-operative blood loss, hepatic inflammatory response, and postoperative complications.

Objective:To investigated the correlation between vascular remodeling pattern and perforator stroke after stenting in patients with symptomatic intracranial vertebrobasilar artery stenosis.Methods:Patients with symptomatic intracranial vertebrobasilar atherosclerotic stenosis underwent stenting and high resolution magnetic resonance imaging (HR-MRI) from January 2017 to August 2020 were enrolled retrospectively. The data of demography, vascular risk factors, plaque characteristics, operation process and postoperative complications were collected. The plaque characteristics were observed by HR-MRI, and the correlation between vascular remodeling pattern and perforator stroke after stenting was analyzed.Results:A total of 41 patients were enrolled in the analysis. Their age was 60.1±8.8 years (range, 49-77 years). There were 31 males (75.6%). Among them, 21 (51.2%) were positive remodeling, 20 (48.8%) were non-positive remodeling, and 5 (12.2%) had perforator stroke after procedure. The incidence of perforator stroke in the positive remodeling group was significantly higher than that in the non-positive remodeling group (23.8% vs. 0%; P=0.048). The positive remodeling rate of the perforator stroke group was significantly higher than that of the non-perforator stroke group (100.0% vs. 44.4%; P=0.048). Conclusions:Patients with intracranial vertebrobasilar atherosclerotic stenosis and positive vascular remodeling were more likely to have perforator stroke after stenting.

Objective:To explore the application of linkage teaching model between hospitals and colleges based on integration of theory and practice in the course of pediatric nursing skills.Methods:Two undergraduate classes of pediatric nursing in a college in 2017 were selected as the experimental group and the control group by random sampling. The experimental group adopted the combined teaching method of colleges and hospitals based on the integration of truth and practice, while the control group adopted the traditional teaching method. The results of skill operation assessment were compared between the two groups, and the results were evaluated by the self-designed teaching effect evaluation questionnaire.Results:The results of the combined nursing skills teaching in colleges and universities were higher in the experimental group (91.24±3.01) than that in the control group (87.33±2.96), the difference was statistically significant ( t value was 5.027, P<0.05). The evaluation score of teaching effect of the experimental group was 62.61 ± 2.94, which was significantly higher than that of the control group (49.67 ± 7.79) ( t value was 7.965, P<0.05). Conclusions:The combined teaching mode of colleges and hospitals based on the integration of theory and practice is beneficial to improve students′ comprehensive quality and learning effect, further shorten the gap between college theory and clinical practice, and is an effective form of pediatric nursing education.

Objective:To investigate the effect of the artificial facial nerve on the restoration of orbicularis oculi muscle function for unilateral peripheral facial paralysis in rabbit.Methods:Artificial facial nerve was implanted into the rabbit with unilateral peripheral facial paralysis between January 2018 and May 2019. At different time points after operation, the affected orbicularis oculi muscles′ stimulation closure threshold and the synchronism about the motion of the two sides of orbicularis oculi muscles were monitored. T test was used with SPSS 13.0 software. Results:There was no significant difference in the closure threshold of the orbicularis oculi muscle on the 7th and 28th days after artificial facial nerve implantation ( P>0.05). The synchronism of the normal side eye closing movement triggered the affected orbicular oculi muscle movement with the artificial facial nerve was up 19/20 to 20/20 at different times. Conclusions:The artificial facial nerve system had the features of stable working condition and high synchronizing effect for stimulating movement. It could restore the closed eye function in animals with peripheral facial paralysis animals and had great clinical application prospects.

Objective: To study laparoscopic ultrasound assisted hepatectomy in treatment of intrahepatic and extrahepatic bile duct stones. Methods: The data of 52 patients with hepatolithiasis who underwent laparoscopic hepatectomy from May 2014 to January 2019 at the Fuyang District First People's Hospital in Hangzhou were analyzed retrospectively. There were 28 men and 24 women. The median age was 56 years. Operative laparoscopic ultrasonography was used to detect the location, size, distribution of stones and their relations to blood vessels. A total of 43 patients underwent anatomic hepatectomy, while 38 patients underwent choledochoscopic stone extraction. A " T" tube was used according to intraoperative conditions. Results: Laparoscopic surgery was successfully carried out in 50 patients, while conversion to open surgery was required in 2 patients because of adhesions and bleeding. Laparoscopic ultrasonography revealed intrahepatic calcifications in 5 patients and choledochoscopy in 2 patients. Postoperative complications included 5 patients who devleoped abdominal abscesses. The operation time was (289.0±132.0) minutes. The intraoperative blood loss was (451.0±256.0) ml. The hospitalization after operation was (12.0±3.0) days. In 52 patients, 4 patients had residual stones and the residual rate was 7.7%. All of them were completely removed by T-tube sinus 8 weeks after operation. Conclusions Laparoscopic ultrasound helped to detect relevant bile ducts containing stones, reduced chance of bleeding in surgery, helped to clarify location and distribution of stones, improved accuracy of diagnosis, and reduced unnecessary hepatectomy by clearly defining intrahepatic bile duct stones intraoperatively. The residual intrahepatic and intrahepatic bile duct stones rates were reduced, and the safety and accuracy of the operations were improved.

?? [Abstract]? Objective? To discuss the premature parents' recognition and level of acceptance of donated breast milk, and to provide the reference to further developing milk banks and increasing breastfeeding rate in premature infants. Methods? Semi-structured in-depth interviews were conducted among 12 parents of premature infants who were admitted to NICU in a specialized hospital in Shanghai from August to December 2017, and the Colaizzi analysis method was used to analyze data. Results? The premature parents recognized the meaning of the breast milk bank, but the level of acceptance of donated breast milk was not high for reasons such as lack of knowledge, traditional ideologies and the popularity of formula milk. Conclusions? At present, parents of premature infants lack objective recognition of donated breast milk. Hospital and breast milk banks should carry out a series of marketing projects and educate the mass about donated breast milk, in order to improve parents' recognition and acceptance of donated breast milk.
