ABSTRACT

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

ABSTRACT

Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.

ABSTRACT

Objective:To explore the value of lumbar plexus-sciatic nerve block combined with low-dose Remimazolam in elderly proximal femoral nail anti-rotation(PFNA)surgery.Methods:60 elderly patients with PFNA surgery were treated from September 2021 to March 2022 in our hospital.They were randomly divided into Propofol group receiving intravenous general anesthesia with laryngeal mask combined with Propofol(control group, n=30)and Remimazolam group with lumbar plexus-sciatic nerve block with laryngeal mask combined with low-dose Remimazolam anesthesia(experimental group, n=30). Mean arterial pressure(MAP)at different time points, heart rate, awakening quality[laryngeal mask removal time], vigilance / sedative observation(OAA / S)score at 15 min after surgery, observation time and various adverse reactions in anesthesia recovery room(in a postanaesthesia care unit, PACU), Montreal cognitive function scale(MoCA)1 day after operation, visual analog score(VAS)at different time points were compared between the two groups.Results:The levels of MAP and HR at the moments of T1, T2, T3, and T4 were lower in the observation group than in the control group(all P<0.05). The time of laryngeal mask removal was shorter in the observation group than in the control group[(8.7±1.3)min and(12.3±1.4)min, t=7.09, P<0.001]. The OAA/S scale value at 15 min after surgery was higher in the observation group than in the control group[(4.6±0.3)and(4.1±0.5), t=4.841, P<0.001]. The incidence of adverse reactions was lower in the observation group than in the control group(3.3% and 20%, χ2=4.043, P=0.044). Visual analogue scale(VAS)value at 3, 6 and 9 hour after surgery were lower in the observation group than in the control group(all P<0.05). The MoCA scores at 6 and 12 hours after operation were higher in the observation group than in the control group( P<0.05). Conclusions:Lumbar plexus-sciatic nerve block combined with low-dose Remimazolam in elderly PFNA surgery is effective and safe, which can reduce the intraoperative hemodynamic fluctuations, optimize the patient's recovery quality, facilitate the postoperative cognitive function recovery, reduce the various adverse reactions, and provide the good analgesic effect within 12 hours after operation.

ABSTRACT

Polytrauma represents severe injuries to multiple body regions, which is associated with high risk of complications and mortality. The definition of polytrauma relies on the basic concept of a combination of injuries that cause a life-threatening condition. The authors strongly call on the healthcare community to list polytrauma as a single disease in the international classification of diseases, rather than "disease combination". Because polytrauma has definite etiology and unique pathophysiological changes after polytrauma, treatment models are different from single trauma. Polytrauma can certainly fulfil any practical and nosological criteria of a single disease according to Berlin definition. The authors explore the importance of polytrauma as a single disease in preventive intervention strategies, therapeutic measures and traumatology development in the future.

ABSTRACT

Objective:To study the expression of forkhead box P1 (FOXP1) in intrahepatic cholangiocarcinoma (ICC), and its clinicopathological and prognostic significance.Methods:The clinical data of ICC patients treated with radical resection at Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 1, 2013 to December 12, 2019 were retrospectively analysed. Of 48 ICC patients, there were 24 males and 24 females, with age of (59.1±10.1) years old (range 42 to 83 years old). Their clinicopathological data, including age, gender, tumor size, degree of differentiation, and staging were recorded. Immunohistochemical method was used to detect the expression of FOXP1 protein in ICC cancer tissues and the corresponding adjacent normal tissues. Kaplan-Meier method was used to calculate survival rates and to construct survival curves of patients. Cox regression model was used to analyze factors affecting prognosis of patients.Results:Forty-eight ICC cancer tissues and 40 corresponding paracancerous tissues were collected. The positive rates of FOXP1 proteins in ICC were significantly lower than the adjacent normal tissues [54.2%(26/48) vs. 92.5%(37/40), χ 2=15.76, P<0.05]. The degrees of tumor differentiation, lymph node metastasis, organ invasion and TNM staging were related to expression of FOXP1 ( P<0.05). Forty-two patients were followed-up with a median follow-up time of 11.5 (7.75, 19.25) months. Cox multivariate analysis revealed that invasion to adjacent organs, lymph node metastasis, high TNM staging (stage Ⅲ) and negative expression of FOXP1 were independent risk factors affecting overall survival of ICC patients. The overall survival and recurrence-free survival of FOXP1-positive ICC patients were 17.5 months and 15.5 months, which were significantly higher than the 14.0 months and 11.1 months, respectively, in FOXP1-negative patients. Conclusion:Negative FOXP1 expression was closely correlated with aggressive biological behavior and poor prognosis of ICC. FOXP1 may be used as new diagnostic and therapeutic targets.

ABSTRACT

Objective:To retrospectively assess early risk factor of persistent inflammation, immunosuppression and catabolism syndrome (PICS) in patients with severe polytrauma, in order to deepen the understanding of the pathological changes of chronic critical illness (CCI) after severe polytrauma.Methods:A total of 276 patients with severe polytrauma admitted to Department of Trauma Surgery of Tongji Hospital from March 2019 to December 2020 were enrolled. Inclusion criteria included patients who suffered severe polytrauma, and injury severity score (ISS) ≥27, age ≥18 years old, and had length of hospital stay >15 days. Exclusion criteria included previous medical history of malignancy, or immunological, consumptive, and metabolic diseases. The patient’s clinical characteristics, ISS scores, Glasgow coma scale (GCS), sequential organ failure assessment, APACHEⅡ scores, and nutrition and immune indexes on day 3 after injury were collected. The difference between the PICS group and N-PICS group were performed by Student’s t test, χ2 test or Mann-Whitney U test. The early risk factors were assessed in patients with PICS after severe polytrauma by logistic regression analysis. Results:According to the diagnostic criteria of PICS, all enrolled patients were divided into two groups: PICS group ( n=102) and N-PICS group (without PICS, n=174). Compared with the N-PICS group, patients in the PICS group were older and associated with more brain and chest injuries. On the third day after injury, serum levels of IL-6 and IL-10, and the ratio of Treg cells were significantly higher, the number and ratio of NK cells subset, and the ratio of activated T lymphocyte were significantly lower in the PICS group than in the N-PICS group ( P<0.05). Logistic regression analysis showed that the age>65 years old ( OR=2.375, 95% CI: 1.442-4.531), GCS ≤8 scores ( OR=3.431, 95% CI: 1.843-8.512), IL-10 >10 pg/mL ( OR=2.173, 95% CI: 1.751-5.614), the ratio of Treg cells >7% ( OR=3.871, 95% CI: 1.723-6.312), and the occurrence of traumatic brain and chest injuries ( OR=2.846, 95% CI: 1.522-5.361) were the early risk factors in patients with PICS after severe polytrauma. Conclusions:Age>65 years old, GCS score, IL-10, the ratio of Treg cells, and the occurrence of traumatic brain and chest injuries could be used as the early risk factors in patients with PICS after severe polytrauma. The discovery of early risk factors will help identify patients at high risk of PICS after severe polytrauma, and create the possibility for early intervention.

ABSTRACT

Laparoscopic cholecystectomy (LC) is the first preferred treatment of benign gallbladder diseases such as gallbladder stones and gallbladder polyps, however bile duct injury is a serious complication of LC. Although bile duct injury is a rare complication, improper treatments will seriously affect the quality of life or even threaten life. Therefore, the prevention and correct treatments of bile duct injury in LC are crucial. Based on domestic and overseas researches, the authors investigate risk factors for bile duct injury in LC, share experiences of timely detection, diagnosis and treatment, so as to provide references for hepatic and biliary surgeons.

ABSTRACT

Objective:To prospectively assess clinical characteristics, potential causes and prognosis in patients with persistent inflammation, immunosuppression and catabolism syndrome (PICS) after polytrauma.Methods:Totally 1 083 patients with polytrauma admitted to Department of Traumatic Surgery of Tongji Hospital from Janury 2019 to July 2020 were enrolled. Exclusion criteria included age<18 years old, length of hospital stay<15 days, previous medical history of malignancy, or immunological, consumptive, and metabolic diseases. According to the diagnostic criteria of PICS, all enrolled patients were divided into two groups: PICS group and N-PICS group (without PICS). The patient’s clinical characteristics, ISS score, GCS score, SOFA score, and prognosis were collected. The χ2 test or Student’s t test was uesd to compare the difference between the PICS group and N-PICS group. Results:The incidence of PICS in patients with polytrauma was 11.7% (127/1 083). The majority of PICS patients were middle-aged and elderly men, 68.5% with traumatic brain injury and 59% with thoracic injury. GCS score was significantly lower, while ISS, APACHE II and SOFA scores were significantly higher in the PICS group than in the N-PICS group ( P<0.01, P<0.05). Among PICS patients, 79.5% were treated with mechanical ventilation and 76.3% were associated with pulmonary infection, with a 28-day mortality of 5.5% and a 180-day mortality of 16.5%, which were siginifcantly different from those without PICS. Conclusions:PICS has a high incidence after polytrauma and is commonly seen in middle-aged and elderly male patients with severe polytrauma, especially accompanied by traumatic brain injury or/and thoracic injury. Patients with PICS after polytrauma have poor long-term prognosis, so early identification and intervention should be strengthened in clinical practice.

ABSTRACT

The effects of sepsis on the liver include hypoxic hepatitis caused by ischemia and shock, liver cell damage caused by excessive inflammation, and cholestasis caused by changes in bile metabolism. Among them, cholestasis is a common complication in patients with sepsis. Cholestasis and jaundice in patients with sepsis are associated with an increased risk of infection, leading to an increased mortality rate. So far, the exact mechanism of sepsis with cholestasis is still unclear, so this article briefly reviews the mechanism of cholestasis during the early stage of sepsis.

ABSTRACT

Objective:To retrospectively assess the relationship between immune disorder and acute gastrointestinal injury (AGI) in patients after severe polytrauma.Methods:Totally 205 patients with severe polytrauma admitted to Tongji Hospital from April 2018 to October 2019 were enrolled as the observation group, and 23 healthy volunteers were served as the control group. According to the diagnostic criteria of AGI, all patients were divided into the AGI group (with AGI) or N-AGI group (without AGI), AGI patients were divided into the S-AGI group or L-AGI group according to the severity. The levels of cytokines and lymphocyte subset were evaluated at day 1, 7, and 14 after severe polytrauma. The differences between groups were statistically analyzed. The independent risk factors of AGI were analyzed by Logistic regression analyzed.Results:Totally 79.5% (163/205) of patients with severe polytrauma were accompanied by AGI. There were significant differences in the ratio of Tc, Th at day 1 after trauma, the levels of IL-6, TNF-α, IL-8, IL-10, the ratio of Ts, Th/Ts, Treg at day 7 after trauma, and the levels of IL-8, IL-10,the ratio of Ts, Th/Ts, Treg at day 14 after trauma between the AGI group and N-AGI group ( P<0.05). There were significant differences in the ratio of Tc, Th, the levels of IL-6, TNF-α at day 1 after trauma and the ratio of Ts, Th/Ts, Treg, the levels of IL-8, IL-10 at day 7 and 14 after trauma between the S-AGI group and L-AGI group ( P<0.05). Logistic regression analysis showed that Ts 7 d ( OR=2.018, 95% CI: 1.105-5.364, P=0.013), Treg 14 d ( OR=3.612, 95% CI: 1.375-8.476, P=0.006), IL-6 7 d ( OR=1.824, 95% CI: 1.011-5.835, P=0.024), IL-10 14 d ( OR=2.847, 95% CI: 1.241-6.216, P=0.014), TNF-α 7 d ( OR=1.754, 95% CI: 1.215-5.441, P=0.018) were independent risk factors in patients with AGI after severe polytrauma. Conclusions:AGI is more easily occurred in patients with the heavier immune disorders after severe polytrauma. AGI can also aggravate pre-existing immune disorders in patients after severe polytrauma.

ABSTRACT

OBJECTIVES@#Perioperative neurocognitive disorders (PND) is one of the important factors affecting the recovery of the elderly after surgery, and sleep disorders are also one of the common diseases of the elderly. Previous studies have shown that the quality of postoperative sleep may be factor affecting postoperative cognitive function, but there are few studies on the relationship between preoperative sleep disorders and postoperative cognitive dysfunction. This study aims to explore the relationship between preoperative sleep disorders and postoperative delayed neurocognitive recovery in elderly patients, and provide references for improving the prognosis and quality of life of patients.@*METHODS@#This study was porformed as a prospective cohort study. Elderly patients (age≥65 years old) underwent elective non-cardiac surgery at Xiangya Hospital of Central South University from October 2019 to January 2020 were selected and interviewed 1 day before the operation. The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) were used to assess the patient's baseline cognitive status. Patients with preoperative MMSE scores of less than 24 points were excluded. For patients meeting the criteria of inclusion, Pittsburgh Sleep Quality Index (PSQI) scale was used to evaluate the patients, and the patients were divided into a sleep disorder group and a non-sleep disorder group according to the score. General data of patients were collected and intraoperative data were recorded, such as duration of surgery, anesthetic time, surgical site, intraoperative fluid input, intraoperative blood product input, intraoperative blood loss and drug use. On consecutive 5 days after surgery, Numerical Rating Scale (NRS) was used to evaluate the sleep of the previous night and the pain of the day, which were recorded as sleep NRS score and pain NRS score; Confusion Assessment Method for ICU (CAM-ICU) scale and Confusion Assessment Method (CAM) scale were used to assess the occurrence of delirium. On the 7th day after the operation, the MMSE and MoCA scales were used to evaluate cognitive function of patients. We compared the incidence of postoperative complications, the number of deaths, the number of unplanned ICU patients, the number of unplanned secondary operations, etc between the 2 groups. The baseline and prognosis of the 2 groups of patients were analyzed by univariate and multivariate logistics to analyze their correlation.@*RESULTS@#A total of 105 patients were collected in this study, including 32 patients in the sleep disorder group and 73 patients in the non-sleep disorder group. The general information of the 2 groups, such as age, gender, body mass index, and surgery site, were not statistically significant (all @*CONCLUSIONS@#Preoperative sleep disorders can increase the risk of delayed neurocognitive function recovery in elderly patients. Active treatment of preoperative sleep disorders may improve perioperative neurocognitive function in elderly patients.

ABSTRACT

Objective:To retrospectively assess the occurrence and risk factors in patients with acute gastrointestinal injury (AGI) after polytrauma.Methods:Totally 430 patients with polytrauma admitted to Tongji Hospital from April 2018 to October 2019 were enrolled as the observation group. According to the diagnostic criteria of AGI, all patients were divided into the AGI group (with AGI) or N-AGI group (without AGI). The patients with abdominal injury or previously suffered from gastrointestinal disease were excluded. The patient's clinical characteristics lab tests results, and the first ISS, APACHEⅡ, SOFA and GCS scores were collected. The differences between different groups were statistically analyzed. The independent risk factors of AGI were analyzed by Logistic regression.Results:65.3% of patients with polytrauma were accompanied by AGI (281/430 cases).There were significant differences between the AGI group and N-AGI group in ISS, GCS, APACHE Ⅱ and SOFA score, PCT or IL-6 level, shock index and length of stay in ICU ( P<0.05). Logistic regression analysis showed that shock, ISS≥16, APACHE Ⅱ≥16, SOFA≥5, GCS≤8 and IL-6>50 pg/mL were the early independent risk factors in patients with ACI after polytrauma. Conclusion:The incidence of AGI in patients after polytrauma is higher, which is related to ischemia, hypoxia, abnormal blood coagulation and stress in the early stage after trauma.

ABSTRACT

Objective To investigate the effects of the extent of regional lymph node dissection on the prognosis of patients with T4 gallbladder carcinoma.Methods The retrospective cohort study was conducted.The clinicopathological data of 64 patients with T4 gallbladder carcinoma who underwent radical cholecystectomy in the 4 medical centers between January 2013 and December 2016 were collected,including 31 in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University,16 in the First Affiliated Hospital of Xi'an Jiaotong University,11 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and 6 in the Affiliated Hospital of North Sichuan Medical College.There were 27 males and 37 females,aged from 35 to 77 years,with a median age of 59 years.Sixty-four patients underwent radical cholecystectomy and regional lymph node dissection.According to the extent of intraoperative lymph node dissection,25 patients (13 in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University,6 in the First Affiliated Hospital of Xi'an Jiaotong University,4 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and 2 in the Affiliated Hospital of North Sichuan Medical College) whose extent of lymph node dissection involved lymph nodes next to cystic duct,hepatoduodenal ligament,back of head of pancreas,next to common hepatic artery and celiac trunk were allocated into the extended dissection group,39 patients (18 in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University,10 in the First Affiliated Hospital of Xi'an Jiaotong University,7 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and 4 in the Affiliated Hospital of North Sichuan Medical College) whose extent of lymph node dissection involved lymph nodes next to cystic duct and hepatoduodenal ligament were allocated into the control group.Observation indicators:(1) postoperative complications;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative overall survival up to January 2018.Measurement data with normal distribution were represented as Mean±SD,and comparison between groups was evaluated with the independentsample t test.Count data were represented as absolute number or percentage,and comparison between groups was analyzed using the chi-square test and Fisher exact probability.The survival curve was drawn using the KaplanMeier method,and the comparison of survival rates was done by the Log-rank test.Results (1) Postoperative complications:64 patients with T4 gallbladder carcinoma underwent successful radical cholecystectomy and regional lymph node dissection,without intraoperative death.Twelve patients had different degrees of postoperative complications.Four of 7 patients undergoing extended radical cholecystectomy had postoperative complications.Twenty-five patients in the extended dissection group were cured by conservative treatment,including 4 with intraperitoneal infection and 2 with pancreatic leakage,with a complication incidence of 24.0% (6/25).Thirtynine patients in the control group were cured by conservative treatment,including 5 with intraperitoneal infection and 1 with gastric retention,with a complication incidence of 15.4% (6/39).There was no statistically significant difference in the complication incidence between the two groups (x2=0.284,P>0.05).(2) Follow-up and survival situations:64 patients were followed up for 1-60 months.The postoperative overall median survival time was l l months.The postoperative median survival time,1-,3-and 5-year cumulative survival rates were respectively 18 months,80%,16%,9% in the extended dissection group and 8 months,21%,4%,0 in the control group,with a statistically significant difference in the prognosis between the two groups (x2=14.744,P< 0.05).Conclusions On the premise of practiced surgical skill,extended regional lymph node dissection cannot increase incidence of surgical complication in patients with T4 gallbladder carcinoma after radical resection.Actively extending lymph node dissection up to near common hepatic artery,peri-celiac trunk and back of head of pancreas can improve long-term survival and prognosis.

ABSTRACT

Objective To determine the value of lymph node ratio (LNR) in prognosis of patients with intrahepatic cholangiocarcinoma (ICC).Methods The pathological and survival data of ICC patients were extracted from the Surveillance Epidemiology and End Result Database (SEER).The value of LNR in prognosis of patients with intrahepatic cholangiocarcinoma was evaluated by the Kaplan-Meier and Cox proportional hazard models.Results A total of 357 pathologically confirmed ICC patients were included in this study (158 males,199 females).The results showed that patients with lymph node metastasis had significantly shorter survival time than patients without metastasis [(41.6 ± 1.8) vs.(23.2 ± 2.2) months,P< 0.05].Multivariate analysis on survival showed that the status of lymph node metastasis was independent prognostic factor of survival,after adjusting for age,gender and tumor stage.Only a LNR ≥ 20% was an independent risk factor of prognosis (HR=2.3,95%CI:1.4~3.8,P<0.05).Conclusion A positive lymph node ratio was superior to lymph node metastasis in predicting survival in patients with intrahepatic cholangiocarcinoma.

ABSTRACT

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy with an increasing incidence and mortality in recent years.Despite advanced improvements in its diagnosis and therapy,the prognosis for ICC patients remains poor.High heterogeneity and malignant biological behavior are the main factors determining the prognosis of ICC.An in-depth study of the mechanism of ICC invasion and metastasis is expected to help optimizing clinical decision-making.The application of advanced technologies such as next-generation sequencing has enhanced the researchers' understanding of heterogeneity of ICC and characteristics of invasion and metastasis.Studies have found that ICC gene expression abnormalities (gene mutations,fusion gene formation,and abnormalities in gene expression regulatory pathways) and microRNA expression disorders are closely related to ICC cell proliferation,invasion and metastasis.In addition,ICC is usually characterized by a dense desmoplastic stroma,in which cancer-associated myofibroblasts are the major cellular components and play an important role in inducing epithelial-mesenchymal transition,promoting malignant cell invasion and metastasis,and even accelerating ICC progression.

ABSTRACT

OBJECTIVE@#To explore the analgesic mechanism of intrathecal trichostatin A (TSA) injection in a rat model of neuropathic pain induced by chronic constrictive injury (CCI).@*METHODS@#Male SD rats were randomized into sham operation+ DMSO group (group S), CCI +DMSO group (group C), CCI +10 μg TSA group (group T), and in the latter two groups, rat models of neuropathic pain were established induced by CCI. The rats were given intrathecal injections of 10 μL 5% DMSO or 10 μg TSA (in 5% DMSO) once a day on days 7 to 9 after CCI or sham operation. The rats were euthanized after behavioral tests on day 10, and the lumbar segment of the spinal cord was sampled to determine the expression of histone deacetylase 4 (HDAC4) protein and mRNA and detect the differentially expressed miRNAs using a miRNA chip. MiR-190b-5p and miR-142-3p were selected for validation of the results using RT-qPCR.@*RESULTS@#Compared with those in group S, the rats in group C showed significantly decreased paw withdrawal mechanical threshold (PWMT) from day 3 to day 10 after CCI ( < 0.05); intrathecal injection of TSA significantly reversed the reduction of PWMT following CCI ( < 0.05). Positive HDAC4 expression was detected mainly in the cytoplasm of the neurons in the gray matter of the spinal cord, and was obviously up-regulated after CCI ( < 0.05). Intrathecal injection of TSA significantly suppressed CCI-induced up-regulation of HDAC4 at 10 days after the operation ( < 0.05). Compared with the miRNA profile in group S, miRNA profiling identified 83 differentially expressed miRNAs in group C (fold change ≥2 or ≤0.5, < 0.05); TSA treatment reversed the expressions of 58 of the differentially expressed miRNAs following CCI, including 41 miRNAs that were decreased after CCI but up-regulated following TSA treatment. The results of real-time PCR validated the changes in the expressions of miR-190b-5p and miR-142-3p.@*CONCLUSIONS@#TSA suppresses CCI-induced up-regulation of HDAC4 and reverses differential expressions of miRNAs in the spinal cord of rats, which may contribute to the analgesic effect of TSA on neuropathic pain.

Intrahepatic cholangiocarcinoma (ICC) is a malignant liver tumor derived from the epithelial cells of the second- or higher-order branch of the bile duct, with the features of insidious early symptoms, high degree of malignancy, rapid disease progression, lymph node metastasis, intrahepatic metastasis, and vascular invasion, and such patients tend to have poor prognosis. Early diagnosis can improve the radical resection rate and prognosis of ICC. At present, the preoperative diagnosis of ICC mainly relies on imaging technology, laboratory examination, and pathological examination. In addition, some new diagnostic methods have also been used in the diagnosis of ICC in recent years, but histopathological examination remains the only method for the diagnosis of ICC. This article reviews the latest research advances in the diagnosis of ICC.

ABSTRACT

Objectives@#To propose a novel clinical classification system of gallbladder cancer, and to investigate the differences of clinicopathological characteristics and prognosis based on patients who underwent radical resection with different types of gallbladder cancer.@*Methods@#The clinical data of 1 059 patients with gallbladder cancer underwent radical resection in 12 institutions in China from January 2013 to December 2017 were retrospectively collected and analyzed.There were 389 males and 670 females, aged (62.0±10.5)years(range:22-88 years).According to the location of tumor and the mode of invasion,the tumors were divided into peritoneal type, hepatic type, hepatic hilum type and mixed type, the surgical procedures were divided into regional radical resection and extended radical resection.The correlation between different types and T stage, N stage, vascular invasion, neural invasion, median survival time and surgical procedures were analyzed.Rates were compared by χ2 test, survival analysis was carried by Kaplan-Meier and Log-rank test.@*Results@#Regional radical resection was performed in 940 cases,including 81 cases in T1 stage,859 cases in T2-T4 stage,119 cases underwent extended radical resection;R0 resection was achieved in 990 cases(93.5%).The overall median survival time was 28 months.There were 81 patients in Tis-T1 stage and 978 patients in T2-T4 stage.The classification of gallbladder cancer in patients with T2-T4 stage: 345 cases(35.3%)of peritoneal type, 331 cases(33.8%) of hepatic type, 122 cases(12.5%) of hepatic hilum type and 180 cases(18.4%) of mixed type.T stage(χ2=288.60,P<0.01),N stage(χ2=68.10, P<0.01), vascular invasion(χ2=128.70, P<0.01)and neural invasion(χ2=54.30, P<0.01)were significantly correlated with the classification.The median survival time of peritoneal type,hepatic type,hepatic hilum type and mixed type was 48 months,21 months,16 months and 11 months,respectively(χ2=80.60,P<0.01).There was no significant difference in median survival time between regional radical resection and extended radical resection in the peritoneal type,hepatic type,hepatic hilum type and mixed type(all P>0.05).@*Conclusion@#With application of new clinical classification, different types of gallbladder cancer are proved to be correlated with TNM stage, malignant biological behavior and prognosis, which will facilitate us in preoperative evaluation,surgical planning and prognosis evaluation.

ABSTRACT

Intrahepatic cholangiocarcinoma(ICC) is the second common primary liver cancer originated from epithelium of the sub-branches of intrahepatic bile ducts with extremely poor prognosis and lack of effective treatment.The prognosis of ICC is mostly affected by the origin,the type and the size of the tumor as well as the intrahepatic metastasis(satellite lesion) and lymph node metastasis etc.Surgical resection remains the first choice of treatment to patients with ICC.However, there are multiple issues in surgical treatment of ICC, which have not been reached a consensus.Among them, the value of systematic lymphadenectomy during hepatic resection for ICC patient remains one of the hot spot issues.Given the heterogeneity of ICC,we recommend planning the procedure of the radical resection and lymphadenectomy personally, according to the type and origin of the tumor, the number and locationof the lesion.The pre-operation imaging examination and the intra-operation lymph node tracing technique could provide valuable information to help the surgeon decide the range of systematic lymphadenectomy.Routine systematic lymphadenectomy is recommended in the surgical treatment of ICC patients by experienced surgeons even without evidence of lymph node metastasis.The resected lymph tissue should be labeled by the provenance for further study.

ABSTRACT

Hilar cholangiocarcinoma is one of the most difficult malignant tumors to treat in the biliary system. In Japan, 5-year survival rate of the disease has increased from 32.5% to 67.1% during the past 30 years. The impressive progress reflects the solid efforts in preoperative endoscopic diagnosis, innovation in surgery such as PTPE as well as hepato-pancreatoduodenectomy and perioperative treatment including replacement of the bile and synbiotic treatment, which have finally formed a set of standardized diagnosis and treatment systems. The present review intends to report the history, current status and remaining bottlenecks of the diagnosis and treatment system of hilar cholangiocarcinoma in Japan as follows.
