Chemotherapy-induced peripheral neurotoxicity (CIPN) is a severe dose-limiting adverse event of chemotherapy. Presently, the mechanism underlying the induction of CIPN remains unclear, and no effective treatment is available. In this study, through metabolomics analyses, we found that nab-paclitaxel therapy markedly increased serum serotonin [5-hydroxtryptamine (5-HT)] levels in both cancer patients and mice compared to the respective controls. Furthermore, nab-paclitaxel-treated enterochromaffin (EC) cells showed increased 5-HT synthesis, and serotonin-treated Schwann cells showed damage, as indicated by the activation of CREB3L3/MMP3/FAS signaling. Venlafaxine, an inhibitor of serotonin and norepinephrine reuptake, was found to protect against nerve injury by suppressing the activation of CREB3L3/MMP3/FAS signaling in Schwann cells. Remarkably, venlafaxine was found to significantly alleviate nab-paclitaxel-induced CIPN in patients without affecting the clinical efficacy of chemotherapy. In summary, our study reveals that EC cell-derived 5-HT plays a critical role in nab-paclitaxel-related neurotoxic lesions, and venlafaxine co-administration represents a novel approach to treating chronic cumulative neurotoxicity commonly reported in nab-paclitaxel-based chemotherapy.

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.

The treatment strategy for colon cancer with liver metastasis has always been a great challenge for clinical surgeons.Single treatment method such as surgical resection or systemic chemotherapy can no longer meet the treatment needs of such patients.With the extensive development of the multi-disciplinary team(MDT)for colorectal cancer based on surgery,more and more patients with advanced colorectal cancer have obtained better treatment effects and survival benefits.A case of descending colon cancer with huge hepatic metastasis diagnosed and treated by a multi-disciplinary team was reported,aiming to provide reference for clinical practice.

Conclusions:With the increase of the operation volume of simultaneous resection of synchronous colorectal liver metastasis, the operation time, time to postoperative initial liquid food intake, postoperative duration of hospital stay and postoperative complications have significantly decreased, while the overall survival rate and disease free survival rate have significantly increased.

Objective: To investigate the effects of treatment of hernia sac stump in laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP) on postoperative seroma. Methods: The prospective study was conducted. The clinical data of 128 male patients with primary indirect inguinal hernia who were admitted to Fujian Medical University Union Hospital from October 2017 to March 2019 were selected. Patients were divided into two groups by random number method. Patients in experimental group had hernia sac stump sutured and fixed at the lower margin of rectus abdominis after transection of hernia sac in TAPP, and patients in control group had hernia sac stump free in the abdominal cavity after dissection and transection of hernia sac in TAPP. Observation indicators: (1) surgical situations; (2) follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect the incidence of postoperative seroma, incision infection, chronic pain, and hernia recurrence up to June 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was done using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was done using the Mann-Whitney U test. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test. Results: A total of 128 male patients were screened for eligibility, including 60 patients in the experimental group and 68 patients in the control group. The 128 patients were aged from 47 to 74 years, with an average age of 61 years. (1) Surgical situations: operation time and hospital expenses were (102±34)minutes and (12 813±2 390)yuan for the experimental group, and (97±30)minutes and (12 125±2 205)yuan for the control group, respectively, showing no significant difference between the two groups (t=0.907, 1.685, P>0.05). (2) Follow-up: all the 128 patients received follow-up. There were 8 cases of seroma in both the experimental group and the control group, with no significant difference between the two groups (χ²=0.072, P>0.05). The extraction volume of patients with seroma was 20 mL (range, 4-31 mL) in the experimental group, and 43 mL (range, 23-98 mL) in the control group, showing a significant difference between the two groups (Z=-2.013, P<0.05). There was no incision infection, chronic pain or hernia recurrence in 3 months after operation in patients with seroma of either experimental group or control group. Conclusions During TAPP, suture and fixation of the hernia sac stump to the lower edge of rectus abdominis and free hernia sac stump in the abdominal cavity after dissection and transection of hernia sac can effectively repair indirect inguinal hernia. The former method can reduce the extraction volume of seroma after operation.

OBJECTIVE: To investigate the surgical efficacy and prognostic factors of T3NxM0 middle-low rectal cancer without neoadjuvant therapy. METHODS: Clinical data of patients with middle-low rectal cancer undergoing TME surgery with T3NxM0 confirmed by postoperative pathology at Colorectal Surgery Department of Changhai Hospital from January 2008 to December 2010 were analyzed retrospectively. INCLUSION CRITERIA: (1)no preoperative neoadjuvant chemoradiotherapy (nCRT); (2) complete preoperative evaluation, including medical history, preoperative colonoscopy or digital examination, blood tumor marker examination, and imaging examination; (3) distance between tumor lower margin and anal verge was ≤ 10 cm; (4) negative circumferential resection margin (CRM-). Finally, a total of 331 patients were included in this study. According to the number of metastatic lymph node confirmed by postoperative pathology, the patients were divided into N0 group without regional lymph node metastasis (190 cases) and N+ group with regional lymph node metastasis (141 cases). The perioperative conditions, local recurrence, distant metastasis and prognostic factors were analyzed. RESULTS: Compared to N0 group in the perioperative data, N+ group had higher ratio of tumor deposit [29.8%(42/141) vs. 0, χ²=64.821, P<0.001] and vascular invasion [7.1%(10/141) vs. 0.5%(1/190),χ²=10.860, P<0.001]. There were no significant differences in tumor diameter, number of lymph nodes detected, positive nerve invasion, degree of tumor differentiation, morbidity of postoperative complication and postoperative adjuvant chemotherapy rate between the two groups (all P>0.05). The median follow-up period was 73.4 months. The merged 5-year local recurrence rate was 2.7%(9/331), 5-year distant metastasis rate was 23.3% (77/331), 5-year disease-free survival (DFS) rate was 73.4%, and 5-year overall survival (OS) rate was 77.2%. Multivariate analysis showed that lymph node metastasis (HR=3.120, 95%CI: 1.918 to 5.075, P<0.001), nerve invasion (HR=0.345, 95%CI: 0.156 to 0.760, P=0.008) and vascular invasion (HR=0.428, 95%CI: 0.189 to 0.972, P=0.043) were independent risk factors for DFS in patients with T3NxM0 rectal cancer after operation. Preoperative carcinoembryonic antigen level (HR=1.858, 95%CI:1.121 to 3.079, P=0.016), lymph node metastasis (HR=3.320, 95%CI: 1.985 to 5.553, P<0.001) and nerve invasion (HR=0.339, 95%CI: 0.156 to 0.738, P=0.006) were independent risk factors for OS in patients with T3NxM0 rectal cancer after operation. CONCLUSIONS Optimal local control rate of middle-low rectal cancer patients with T3NxM0 and CRM- can be achieved by standard TME surgery alone. For patients with preoperative elevated blood carcinoembryonic antigen level, regional lymph node metastasis, or neurovascular invasion confirmed by pathology after surgery, adjuvant chemoradiotherapy should be actively applied after surgery to improve prognosis.

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.
