Objective:To investigate the application value of robot-assisted parenchyma-sparing pancreatectomy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 54 patients who underwent robot-assisted parenchyma-sparing pancrea-tectomy in the Fujian Medical University Union Hospital from January 2017 to February 2023 were collected. There were 22 males and 32 females, aged (44±16)years. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the rank sum test. Count data were expressed as absolute numbers, and comparison between groups was performed using the Fisher exact probability. Results:(1) Intraoperative conditions. All 54 patients underwent robot-assisted parenchyma-sparing pancrea-tectomy successfully, without conversion to laparotomy. Of 54 patients, 32 cases underwent pancreatic tumor enucleation and 22 cases underwent central pancreatectomy. Of the 32 patients who underwent pancreatic tumor enucleation, 29 cases underwent conventional pancreatic tumor enucleation, and 3 cases underwent intraoperative repairing of main pancreatic duct injury. Of the 22 patients who underwent central pancreatectomy, 15 cases underwent end-to-end anastomosis, and 7 cases underwent Roux-en-Y pancreaticojejunostomy. There was no significant difference in operation time or volume of intraoperative blood loss between 29 patients undergoing conventional pancreatic tumor enucleation and 3 patients undergoing intraoperative repairing of main pancreatic duct injury ( t=-1.66, Z=-0.82, P>0.05). There were significant differences in operation time and volume of intraoperative blood loss between 15 patients undergoing end-to-end pancreatic anastomosis and 7 patients undergoing Roux-en-Y pancreaticojejunostomy ( t=-3.03, Z=-2.22, P<0.05). (2) Postoperative conditions. There were 38 of the 54 patients with postoperative complications, including 37 cases of pancreatic fistula and 1 case of delayed gastric emptying. There was no significant difference in post-operative pancreatic fistula between 29 patients undergoing conventional pancreatic tumor enuclea-tion and 3 patients undergoing intraoperative repairing of main pancreatic duct injury ( P>0.05). There was a significant difference in postoperative pancreatic fistula between 15 patients under-going end-to-end pancreatic anastomosis and 7 patients undergoing Roux-en-Y pancreaticojejunostomy ( P<0.05). (3) Follow-up. All 54 patients were followed up for 23(range, 3-76)months, and all of them survived without tumor recurrence or metastasis. None of the 32 patients undergoing enuclea-tion of pancreatic tumor experienced pancreatic endocrine or exocrine insufficiency. Of the 15 patients who underwent end-to-end pancreatic anastomosis, there were 2 cases of dilatation of the main pancreatic duct and atrophy of the distal pancreas, 1 case of pancreatic endocrine insufficiency and 1 case of exocrine insufficiency. Of the 7 patients who underwent Roux-en-Y pancreaticojejunostomy, there was 1 case of pancreatic endocrine insufficiency. Conclusion:Robot-assisted parenchyma-sparing pancreatectomy can provide intraoperative protection, repair and anastomosis of the main pancreatic duct.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective:To explore the efficacy and safety of anti-tumor necrosis factor alpha (TNFα) monoclonal antibodies (mAbs) for severe/refractory vasculo-Behcet′s disease (BD).Method:The clinical data of severe/refractory vasculo-BD patients treated with anti-TNFα mAbs were retrospectively analyzed. Response of anti TNFα mAbs was analyzed. The dosage changes of glucocorticoid, the level of erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hsCRP) before and after treatment were recorded, as well as side effects.Result:Sixteen patients were enrolled. Arterial lesions were reported in 12 patients, including 9 with arterial aneurysm, 6 with arterial dilation, 2 with stenosis and 2 with occlusion. Seven patients presented venous thrombosis, including lower extremity veins ( n=6), cerebral venous sinus ( n=2) and inferior vena cava system ( n=2). Two cases had both arterial and venous involvement. Before the application of TNFα mAbs, all 16 patients failed to response to prednisone or its equivalent dose of 40 (7.5-90) mg/d in combination with cyclophosphamide, methotrexate, thalidomide or azathioprine for median 4 (0-156) months. After a mean duration of treatment for (17.1±6.5) months, 15 patients achieved complete remission and 1 patient achieved partial remission. Three patients received surgery without any postoperative complications. After using anti TNFα mAbs, the dosage of prednisone [5(0-12.5)mg/d vs. 40(7.5-90)mg/d, P<0.01], ESR [(7.3±4.6) mm/1h vs. (33.5±26.7) mm/1h, P<0.01] and hsCRP [1.9(0.2-11.4) mg/L vs. 24.3(0.4-113.9) mg/L, P<0.01] were significantly decreased. Side effects were observed in 2 patients. One developed pulmonary infection 12 months after adalimumab with conventional treatment. Another patient had allergy to infliximab then switched to adalimumab. Conclusion:In combination with corticosteroids and immunosuppressants, anti-TNF α mAbs are effective and well-tolerated in severe/refractory vasculo-BD, with a favorable steroid -sparing effect and rare postoperative complications.

Objective: To compare the short-term clinical outcomes and cost differences of robotic distal pancreatectomy (RDP) versus laparoscopic distal pancreatectomy (LDP). Methods: The retrospective descriptive study was adopted.The clinical data of 158 patients underwent minimally invasive distal pancreatectomy who were admitted to Fujian Medical University Union Hospital between January 2016 and July 2018 were collected.A 1∶1 matched propensity score (PSM) analysis was performed for the RDP group and the LDP group.Observed indexes included operative time, blood loss, spleen-preserving rate, postoperative hospital stay, morbidity, incidence of pancreatic fistula and hospital costs. T test or rank sum test was used to compare measurement data, χ² test or Fisher exact test was used to compare count data. Results: A well-balanced cohort of 41 patients was analyzed.There were 14 males and 27 females in the RDP group, aged (45.2±16.4)years. There were 15 males and 26 females in the LDP group, aged (47.4±14.9) years.The operation time was (209.7±52.9) minutes for the RDP group and (186.5±56.7) minutes for the LDP group (P=0.073). Median blood loss was less in RDP (50(15-175)ml) compared with LDP (100(50-350)ml) (Z=-2.689, P=0.007). Thirty-eight cases of non-malignant diseases were observed in each group and spleen-preserving rate was higher in RDP (76.3%) compared to LDP(44.7%) (χ²=7.930, P=0.005).Postoperative hospital stay was similar in the RDP group and the LDP group (RDP: 9.4 days vs. LDP: 10.6 days; P=0.372). The overall morbidity and incidence of pancreatic fistula major complication rates (RDP: 12.2% vs. LDP: 14.6%, P=0.746; RDP: 7.3% vs. LDP: 9.8%, P=1.000) were similar.Total cost of RDP group was higher than that of LDP group ((80 563.7±10 641.8) yuan vs. (57 792.8±8 943.0) yuan, t=4.515, P<0.01). Conclusions Both RDP and LDP are safe and feasible procedures. RDP is more expensive, but RDP is associated with significantly less blood loss and higher spleen-preserving rate, which is more suitable for the non-malignant diseases of pancreatic body and tail with an expectation of splenic preservation.

Objective To explore the clinical effects of laparoscopic combined with open mesh repair for abdominal wall incisional hernia.Methods The retrospective cross-sectional study was conducted.The clinical data of 41 patients with abdominal incisional hernia who were admitted to the Fujian Medical University Union Hospital between September 2011 and June 2017 were collected.All the patients underwent laparoscopic combined with open mesh repair,with the sequence from laparoscopic surgery to open surgery and then to laparoscopic surgery.Observation indicators:(1) intra-and post-operative situations;(2) follow-up situation.Follow-up using outpatient examination and telephone interview was performed to detect postoperative long-term complications and hernia recurrence up to November 2017.Measurement data with normal distribution were represented as (x)±s.Results (1) Intra-and post-operative situations:forty-one patients underwent successful laparoscopic combined with open mesh repair for abdominal wall incisional hernia.Diameter of hernia ring and defect area of abdominal wall were respectively (10±3)cm and (75±34)cm2.Among 41 patients,25 underwent laparoscopic combined with open mesh repair due to tight intestinal adhesion induced difficult laparoscopic separation;16 underwent laparoscopic combined with open mesh repair due to the larger diameter of the hernia ring induced difficulty of closing hernia ring under laparoscope.Operation time,cases with indwelling drainage-tube,time of drainage-tube removal and duration of postoperative hospital stay were respectively (188±71)minutes,33,(14±3)days and (4.5±2.6)days.Of 41 patients,2 with postoperative incomplete intestinal obstruction were cured by symptomatic treatment;2 with incisional infection were cured by antibiotic therapy,irrigation and dressing change.(2) Follow-up situation:41 patients were followed up for (29±17)months.The postoperative chronic pain of 2 patients was occasional and cannot affect the normal life.There was no occurrence of seroma,mesh infection,intestinal fistula,abdominal compartment syndrome and hernia recurrence during the follow-up.Conclusion The laparoscopic combined with open mesh repair has a better clinical effect for patients of incisional hernia with large hernia ring and tight intestinal adhesion,and surgical methods should be chosen seriously according to the condition of the patients in clinical application.

Objective To investigate the clinical efficacy of laparoscopic resection for retroperitoneal tumor via transabdominal approach.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 37 patients with retroperitoneal tumor who underwent laparoscopic resection via transabdominal approach at Fujian Medical University Union Hospital between January 2011 and August 2017 were collected.The surgical approach of resection for retroperitoneal tumor at the left hypochondriac region,left iliac region,right hypochondriac region and right iliac region referred to laparoscopic distal pancreatectomy,laparoscopic left hemicolectomy,laparoscopic pancreatoduodenectomy and laparoscopic right hemicolectomy respectively.Observation indicators:(1) intra-and post-operative recovery situations;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative tumor recurrence,metastasis and survival of patients up to November 2017.Measurement data with normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M (range).Results (1) Intra-and post-operative recovery situations:37 patients underwent successfully laparoscopic resection for retroperitoneal tumor via transabdominal approach.Among 37 patients,4 were converted to open surgery,4 were completed surgery with assisted small incision,4 were combined with adjacent organ resection and other 25 underwent totally laparoscopic resection for retroperitoneal tumor.The operation time,volume of intraoperative blood loss,postoperative gastrointestinal recovery time,postoperative drainage-tube removal time and duration of postoperative hospital stay were respectively (181±73) minutes,(160±87) mL,(3.0± 1.0) days,(3.0±2.0) days and (7± 4)days.Of 37 patients,3 with postoperative complications including 2 of chylous fistula and 1 of delayed gastric emptying were improved by symptomatic treatment.There was no perioperative death.(2) Follow-up and survival situations:37 patients were followed up for 3-82 months,with a median time of 30 months.During the follow-up,1 patient with inflammatory myofibroblastic tumor had recurrence at 15 months postoperatively and underwent surgical resection,however,the patient had liver metastasis at 9 months after the second operation and underwent interventional therapy repeatly.One patient with Castleman and 5 with lymphoma underwent regular chemotherapy and achieved disease-free survival.The other patients had disease-free survival.Conclusion Laparoscopic resection for retroperitoneal tumor via transabdominal approach is safe and feasible.

Objective To investigate the mediating effects of neurotic personality between parental rearing patterns and depressive symptom.Methods Using multistage sampling method,982 town middle-school students were surveyed by the Symptom Checklist 90(SCL-90),the Egna Minnen av Barndoms Uppfostran (EMBU),the Eysenck Personality Questionnaire (EPQ).Correlation and regression analysis,mediating effect test,and structural equation model were constructed.Results ①)Depressive symptom (D) (1.73 ± 0.72) was significantly associated with Neurotic personality (N) (51.50± 11.37) and parental rearing patterns (r=-0.138-0.582,P＜0.01).②N,mother's rejection and deny(M3),father's emotional warmth and understanding(F1),father's over-protection(F6) had a direct effect on D,which can explain 41.6％ of the variance.F1,F6,mother's over-interference and over-protection(M2),M3 had a direct effect on N,which can explain 15.3％ of the variance.The mediating effect of N between F1,F6,M2 and D were significant(95％CI =-0.212--0.069,-0.351--0.233,0.414-0.480).③The explanation for D was 41.3％.N had completely mediating effect between M2 and depressive symptom.N had partial mediating effect between F1,F6 and D,and the proportion was 43.6％ and 49.1％.Conclusion Neurotic personality plays a mediating role between parental rearing patterns and depressive symptom in middle-school students.

Objective The aim of this study was to evaluate theβ-cell mass ( BCM) in patients with type 2 diabetes mellitus( T2D) by PET/CT using [ 18 F]-FP-(+)-DTBZ, which is a vesicular monoamine transporter type 2 molecular probe. The feasibility of pancreatic head, body and tail as the target area was investigated for evaluation of the BCM in T2D. Methods 15 subjects ( 8 with T2D, and 7 as control) were involved in this study with 20 min static PET imaging at 40 min post injection of [ 18 F]-FP-(+)-DTBZ. The volume of interest ( VOIs) of pancreatic head, body and tail were drawn and quantitatively assessed. Spleens were collected as reference tissue for SUVR calculation. Results SUVR in the pancreatic head ( SUVR=1.72 ± 0.47) and pancreatic body, tail ( SUVR=1.85 ± 0.41) in T2D group was no significant difference, and no significant difference was observed in the pancreatic head (SUVR=2.54±0.57) and pancreatic body, tail(SUVR=2.73±0.41) in control group as well. In T2D group, a significant decreased SUVR was found in pancreatic head (P=0.0088) and pancreatic body and tail (P=0.0012) compared with controls. Conclusion The VMAT2 molecular probe [ 18 F]-FP-(+)-DTBZ can be used to evaluate BCM in patients with T2D.

Objective To investigate the current status and existing problems in the implementation of stroke care continuity in China, and to collect relevant suggestions for solving these problems. Methods Focus group interviews were used, to survey thirty-six nursing managers and senior nurses in neurology departments or rehabilitation programs in 24 cities of 13 provinces. The interview team members presided over the meetings, with full-time staff taking notes and recordings, and the results of the interviews were summarized and organized in a timely manner after the interview. Results At present, most of the general hospitals surveyed are doing their best to continue supporting nursing care for patients discharged from hospitals in different forms following their rescue of the acute phase. However, they are faced with such challenges as insufficient nursing manpower, and discontinuity between different medical institutions, which result in oversimplified nursing care and fragmented care. Conclusions Stroke nursing practitioners are working on continuous nursing care, with quite some challenges as well. Nursing care continuity is an important step towards establishing and improving a scientific and rational grading nursing care system.

Objective To investigate the effect of ulinastatin (UTI) on peripheral CD4 + CD25 + Foxp3 + Treg cells in patients with acute pancreatitis (AP).Methods Between October 2014 to August 2016,127 patients with AP including three types of severity (MAP,MSAP,SAP) admitted to the Affiliated Union Hospital of Fujian Medical University consecutively were divided into two groups (the UTI group and control group).UTI was added to patients in UTI group.Treg cells were measured by flow cytometry,and the levels of IL-10 were detected by enzyme-linked immunosorbent assay (ELISA).Results On the third and seventh day,the percentage of Treg in UTI group (MAP:2.72％ ±0.76％,2.26％ ±0.61％;MSAP:3.04％ ±0.74％,4.12％ ± 1.10％;SAP:4.41％ ±0.86％,5.38％ ± 1.13％) were higher than that of control group (MAP:2.08％ ±0.50％,1.83％ ±0.67％;MSAP:2.24％ ±0.89％,3.25％ ±0.70％;SAP:3.35％ ±0.85％,4.56％ ±0.73％),all P ＜0.05.For patients with MAP,the levels of IL-10 in UTI group (48.85 ± 15.46) were higher than control group (37.43 ± 13.36) only on the third day.For patients with MSAP and SAP,the levels of IL-10 in UTI groups (MSAP:32.95 ± 10.72,59.79 ± 20.09;SAP:22.48 ±3.67,30.91 ±8.74) were higher than control groups (MSAP:25.15 ± 10.05,36.66 ± 16.80;SAP:18.73 ±2.69,23.72 ±5.73) both on the third and seventh day (P ＜0.05).The effective ratio of the treatment in UTI groups were higher than control groups (92.2％ vs.79.4％).Conclusions Ulinastatin regulates the immune function and alleviates inflammatory response during AP by inducing the expansion of Treg cells.
