Objective To investigate the effects of IL-1 β on proliferation and migration of gallbladder cancer cells.Methods The secretion of IL-1 β in tissues of gallbladder cancer, chronic cholecystitis and normal gallbladder as well as in supernatant of gallbladder cancer cell lines (GBC-SD, SGC996) and HIBEpic cells was determined by enzyme-linked immunosorbent assay (ELISA) method.The levels of IL-1 β mRNA in GBC-SD, SGC996 and HIBEpic cells were measured by RT-PCR assay.The effects of exogenous IL-1 β on the proliferation of GBC-SD and SGC996 cells in vitro and in vivo were evaluated using WST-1 assay and xenograft tumor model, respectively.The effects of exogenous IL-1 β on the migration of GBC-SD and SGC996 cells in vitro were measured by Tranwell assay.The levels of Twist protein in GBC-SD and SGC996 ceils were examined by western blot assay after treatment with exogenous IL-1 β.In addition, the proliferation and migration of GBC-SD and SGC996 cells after gene silencing of Twist by Twist-siRNA were also evaluated.Results The level of IL-1β protein in normal gallbladder was low (66.4 ± 35.0)pg/ml,while it was significantly increased in gallbladder cancer and chronic cholecystitis [(616.4 ± 95.7) pg/ml and (422.3 ± 48.9) pg/ml, P < 0.05].The levels of IL-1 βin GBC-SD and SGC996 cell culture medium [(587.4 ± 99.8) pg/ml and (657.2 ± 76.6) pg/ml] were much higher than those in the HIBEpic cells [(38.4± 12.1)pg/ml, P < 0.05].Exogenous IL-1β promoted the proliferation of GBC-SD and SGC996 cells both in vitro and in vivo as well as migration in vitro (P < 0.05).The level of Twist protein was significantly increased after treatment with exogenous IL-1 β.In addition, gene silencing of Twist blocked IL-1 β-induced proliferation and migration of GBC-SD and SGC996 cells.Conclusion IL-1 β promoted proliferation and migration of gallbladder cancer cells via Twist activation.

Objective To analyse the clinical feature of infective endocarditis (IE) in recent years.Methods Clinical profiles including age of onset,predisposing factor,clinical manifestation,blood culture and ultrasonic cardio gram (UCG) of 97 cases from Huashan Hospital in the recent 10 years were collected and analyzed retrospectively. Descriptive data were represented as mean ±standard deviation form.Positive rate was represented as percentage form.Fisher's exact test were used to determine two groups' comparison.Results The mean age of the population was (49±17)years.Seventy-three patients (75.3%) had background heart disease,the top 3 of which was rheumatic heart disease in 27 patients (27.8%),congenital heart disease in 23 patients (23.7%) and idiopathic mitral valve prolapse in 18 patients (18.6 %).The most common clinical manifestation were fever (99.0%),murmurs (95.9%) and anemia (84.5%).Sixty-six patients (68.0%) had positive result of blood cultures. Streptococcus viridans,which was found in 28 patients with native valve endocarditis (42.4 %),was still the most common pathogen.Staphylococcus,which was found in 18patients (27.3%),had an elevated ratio.Staphylococcus aureus was found in 10 patients (15.2%)and 3 of which were MRSA.Coagulase-negative staphylococcus was found in 8 patients (12.1 % ) and 2 of which were MRCNS. Drug-resistant bacteria was increased and pathogens were varied.Vegetations were found in 79 patients (81.4%) by UCG.ConclusionsClinical manifestation,predisposing factor and pathogen have changed in IE patients. Attaching importance to physical examination,multiple-time blood culture and UCG helps the diagnose of IE.

Objective To evaluate the performance of peripheral blood T-SPOT.TB and cerebrospinal fluid (CSF) interferon (IFN)-γ detection in the diagnosis of tuberculous meningitis (TBM).Methods Among the 182 consecutive cases with suspected TBM in Huashan Hospital from March 2011 to March 2013,30 patients were included in the case group according to the latest diagnostic criteria of TBM.Thirty-nine patients diagnosed with non-tuberculous meningitis were included in the control group.T-SPOT.TB was employed to detect tuberculosis-specific IFN-γ-secreting T cells in the peripheral blood.And IFN-γ in CSF was detected simultaneously by enzyme-linked immunosorbent assay (ELISA) without antigen stimulation.The CSF was collected from 10 patients of TBM group after anti tuberculosis treatment for 4 weeks to observe the dynamic changes.The t-test was used for analysis of continuous variables with normal distribution and Kruskal-Wallis test was used for analysis of variables with abnormal distribution.Results ()f the 30 TBM cases,6 were confirmed cases and 24 were highly suspected cases.The control group was comprised of 12 viral encephalitis,16 suppurative meningitis and 11 cryptococcal meningitis.The positive rate of T-SPOT.TB was significantly higher in TBM group compared with control group (70% vs 13%,x2 =12.15,P<0.01).The mean concentration of CSF IFN γ of TBM group was 244.35 pg/mL,which was significantly higher than that of control group 9.48 pg/mL (Z=-4.646,P<0.01).The CSF IFN-γ was significantly decreased after 4 weeks of treatment (271.02 pg/mL vs 81.36 pg/mL,Z=-3.099,P=0.002).The sensitivity and specificity of peripheral blood T-SPOT.TB in the diagnosis of TBM were 70% and 87%,respectively.The area under the receiver operating characteristic (ROC) curve of CSF IFN-γ for TBM diagnosis was 0.819; the optimal cut-off point was 81.36 pg/mL; the corresponding sensitivity and specificity were 83 % and 85 %,respectively.Conclusion Both the detection of peripheral blood T-SPOT.TB and CSF IFN-γ are of great importance for the diagnosis of TBM.Dynamic observation of CSF IFN-γ is important for disease monitoring.

Objective:To assess the occurrence, prognosis and possible early risk factors of jaundice in polytrauma patients.Methods:This study was a single-center, prospective study. Polytrauma patients (age>18 years) admitted to Tongji Trauma Center from October 2020 to January 2023 were enrolled. The patients with liver, biliary tract or pancreatic traumatic injury, previously suffered from chronic liver disease were excluded. The clinical characteristics of patients, laboratory test results, imaging examination results, Injury Severity Score (ISS), Glasgow Coma Score and APACHEⅡ score were collected. The incidence of jaundice, the classification of jaundice or the severity of jaundice after multiple injuries, the mortality rate of polytrauma patients with jaundice, and the early independent risk factors of jaundice in polytrauma were analyzed. The differences between the groups were compared by Student’s t test or χ2 test. The independent risk factors of jaundice were analyzed by Logistic regression analyzed. Results:A total of 742 polytrauma patients were included, 34.09% polytrauma patients were accompanied by jaundice, and the ratio of both moderate and severe jaundice were as high as 32.41%. The main type of jaundice was intrahepatic cholestatic jaundice (47.03%). The mortality rate of polytrauma patients accompanied by jaundice was significantly higher than that of polytrauma patients without jaundice (12.25% vs. 3.47%, P<0.001). Logistic regression analysis showed that ISS score ( OR=3.405, 95% CI: 1.962-7.438, P=0.026), plasma lactate ( OR=2.216, 95% CI: 1.203-4.862, P=0.017), interleukin-6 levels ( OR=2.431, 95% CI: 1.424-3.793, P=0.007), the overall duration of parenteral nutrition ( OR=3.011, 95% CI: 1.624-5.041, P=0.022), and the total duration of mechanical ventilation ( OR=3.572, 95% CI: 1.497-4.601, P=0.031) were the early independent risk factors for jaundice in patients after polytrauma. Conclusions:Polytrauma patients are prone to developing jaundice after injury, which is more harmful, especially for intrahepatic cholestatic jaundice after injury. Early identification and early intervention of risk factors associated with jaundice after injury should be strengthened.
