RESUMO
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.
RESUMO
Objective@#To investigate the fundamental etiology and factors related to the outcome of children with acute liver failure in recent years.@*Methods@#The etiology and factors related to the outcome of pediatric acute liver failure(PALF) patients who hospitalized in Department of Pediatric Intensive Care Unit, Beijing Children′s Hospital, Capital Medical University from August 2007 to July 2017 were retrospectively analyzed.@*Results@#(1)Of 92 children with PALF, there were 47 males and 45 females.(2)The incidence was particularly high in Summer.Morbidity was the highest in infants(38.0%, 35/92 cases), and it was not uncommon in ≤3 year-old children(23.9%, 22/92 cases). (3)Etiology diagnosis was not established in 38 children(41.3%, 38/92 cases). Etiology diagnosis could be established in infectious disease(16.3%, 15/92 cases), metabolic disease(8.7%, 8/92 cases)and mushroom poisoning(7.6%, 7/92 cases). The etiology of PALF was significantly related to age.(4)Twenty-nine cases survived and the survival rate was 31.5%, invalid 63 cases(68.5%, 63/92 cases), of which 14 cases(22.2%, 14/63 cases)died, 49 cases(77.8%, 49/63 cases) gave up treatment or left the hospital by themselves.(5)It showed that the factors significantly correlated with the outcome of PALF were respiratory failure, albumin(ALB), and the peak of total bilirubin (TBIL)(P=0.013, 0.029, 0.002).@*Conclusions@#The outcome of PALF is poor and the survival rate is still low.Morbidity is the highest in infants, and the incidence is particularly high in Summer.Infectious disease is the commonest etiology in children compared with metabolic disease and mushroom poisoning.Its pathogen is still unknown.The etiology of PALF is significantly related to age, respiratory failure, ALB, and the peak of TBIL during hospitalization was the relevant factors for PALF prognosis in this study.
RESUMO
Objective To analyze the clinical characteristics and short-term prognostic factors in acute cerebral infarction patients who underwent recanalization. Methods This retrospective study enrolled 94 cases of acute cerebral ischemic patients in the First Affiliated Hospital of Nanjing Medical University between October 2014 and August 2016. Based on the clinical characteristics of the enrolled patients, a multivariate Logistic regression model was established to analyze the risk factors of unfavorable prognosis. Besides, patients were further divided into good collateral circulation group (1-2) and poor collateral circulation group (3-5) according to the Pial Collateral score, and the prognosis improvement rates between patients recanalized within 4 h and over 4 h were analyzed in each group. Chi-square test or Fisher's exact test was used to analyze statistical difference as indicated. Results By multivariate Logistic regression analysis, age older than 70 years old (OR=2.651, 95％CI: 1.013-6.937)and poor collateral circulation (OR=3.160, 95％CI: 1.113-8.977) were independent risk factors of short-term poor prognosis. In the poor collateral circulation subgroup, patients recanalized within 4 h exerted a relatively better prognosis than patients recanalized over 4 h (42.9％ vs.10.5％, P=0.047). However, the effect of recanalization duration on the prognosis in the good collateral circulation subgroups was not statistically significant (42.9％ vs. 10.5％, P=0.047), however, the effect of recanalization duration on prognosis in patients with good collateral circulation was not statistically significant (58.3％ vs. 37.8％, P=0.117). Conclusions For patients with acute cerebral infarction, age and collateral circulation status may influence the prognosis of recanalization therapy. The treatment time had a significant influence on the prognosis in patients with poor collateral, while it had minimal significance on patients with good collateral.
RESUMO
Objective:To explore the possible specific perinatal risk factors in the development of autism through comparing the perinatal risk factors between patients with autism and other psychotic disorders.Methods: In this retrospective research,197 cases with autism and 93 cases with other psychotic disorders were selected and assessed with the self-made scale of perinatal risk factors.Statistical analyses were performed using t test and Chi-square test.Results:Compared with the control group,the autistic subjects had a significantly higher frequency of the perinatal risk factors(51 % vs.68%,P=0.003),particularly the rate of catching a cold during their mothers' pregnancy(14.2% vs.6.5%,P=0.038)and the rate of prematurity(10.7% vs.3.2%,P=0.022)than the control subjects.Feeding methods was different between the two groups(P=0.038).Conclusion:Catching a cold during mothers' pregnancy,prematurity and feeding methods may be related to the development of autism.
