OBJECTIVE:To establish the detection method for pyrogen-related factor interleukin 1β(IL-1β)through optimiz-ing detection condition,and to conduct preliminary methodology study. METHODS:The in vitro fresh human whole blood detec-tion method was used. The bacterial endotoxin standard solution(5,2,0.8,0.32 EU/ml)were added into diluted blood;using di-luted RPMI 1640 as blank control,the content of IL-1β in blood sample was determined by ELISA after incubation. The relation-ship of the addition of different attenuants(RPMI 1640 culture,sterilized normal saline)and fetal bovine serum,final dilution vol-ume fraction(40%,20%,10%and 8.3%)and storage duration(2,5,6,8,26 h)with the contents of endotoxin IL-1βwere in-vestigated,and related coefficient and detection limits were calculated. Different dilution times of Qingkailing injection and Ginaton injection samples and interference solutions were added into diluted blood to detect their recovery. RESULTS:The results indicated that RPMI 1640 media and 40% diluted blood was more sensitive(detection limit was 0.128 EU/ml,r=0.993);while the addition of fetal bovine serum didn’t influence the results. The detection limits of blood sample storied at 4 ℃ for 26 h were 0.128 EU/ml (r>0.990). When Qingkailing injection and Ginaton injection were diluted 10,32 and more times,the detection method was not interfered and the recovery ranged 68%-118%. CONCLUSIONS:Established in vitro fresh human whole blood detection method can be used for the detection of pyrogen,and provides trial evidence for the pyrogen detection of TCM injection.

TACE.Of 44 HCC patients with BDTT,23 underwent tumor and BDTT resection,21 underwent tumor resection + BDTT removal through incising common bile duct;29 received postoperative TACE.(3) Follow-up and survival:① 220 patients were followed up for 1-73 months,with a median time of 12 months.The median survival time,1-,3-and 5-year survival rates were respectively 12 months,48.2％,25.0％,15.4％ in 140 HCC patients with PVTT and 28 months,77.1％,45.6％,24.5％ in 36 HCC patients with HVTT and 36 months,88.6％,48.3％,24.6％ in 44 HCC patients with BDTT,with a statistically significant difference in survival (x2 =13.316,P＜0.05).② Of 140 HCC patients with PVTT,49 were in type Ⅰ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 20 months,60.3％,32.6％ and 17.1％;70 were in type Ⅱ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 13 months,51.4％,26.0％ and 17.3％;21 were in type Ⅲ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 7 months,9.5％,4.8％ and 0,showing a statistically significant difference in survival (x2=18.102,P＜0.05).The median survival time,1-,3-and 5-year survival rates were respectively 21 months,72.5％,42.5％,26.2％ in 51 patients undergoing tumor and TT resection and 9 months,40％,14.4％,0 in 89 patients undergoing tumor resection + PVTT removal through incising portal vein,showing a statistically significant difference in survival (x2=24.098,P＜0.05).③ Of 36 HCC patients with HVTT,17 were detected in right HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 14 months,64.7％,20.2％ and 0;10 were detected in left HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 53 months,80.0％,70.0％ and 38.9％;9 were detected in middle HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 40 months,88.9％,61.0％ and 30.5％;showing no statistically significant difference in survival (x2 =5.951,P＞0.05).④ Of 44 HCC patients with BDTT,24,6 and 14 were respectively detected in type Ⅰ,Ⅱ and Ⅲ BDTTs,and median survival time,1-,3-and 5-year survival rates were respectively 38 months,87.5％,60.4％,34.9％ in type Ⅰ BDTT patients and 26 months,83.3％,16.7％,0 in type Ⅱ BDTT patients and 35 months,78.6％,50.0％,21.4％ in type Ⅲ BDTT patients,showing no statistically significant difference in survival (x2 =5.312,P＞0.05).Of 44 patients,median survival time,1-,3-and 5-year survival rates were respectively 38 months,91.3％,59.5％,34.3％ in 23 patients undergoing tumor and TT resection and 26 months,85.7％,35.7％,15.3％ in 21 patients undergoing tumor resection + TT removal through incising common bile duct,showing no statistically significant difference in survival (x2 =2.071,P＞0.05).Conclusions HCC patients with PVTT have larger tumor diameter and worse liver dysfunction,and are prone to peritoneal effusion.HCC patients with different LVI undergo surgery.There is better prognosis in HCC patients with BDTT,and good prognosis in patients with HVTT,while poorer prognosis in patients with PVTT.The postoperative survival of HCC patients with PVTT is associated with TT type,and patients will have better prognosis after tumor resection + TT removal if TT type is confirmed earlier.The postoperative survival of HCC patients with BDTT is not associated with TT type,tumor resection + TT removal maybe prolong postoperative survival time.

Objective To investigate the effect of caveolin-1 scaffolding domain (CSD) peptides on heme oxygenase-1 (HO-1) activity increasing and M1/M2 phenotype polarization in rat alveolar macrophages (AMs) induced by lipopolysaccharide (LPS).Methods Bioinformatics was used to analyze the binding of full-length wild-type CSD polypeptide and 101 amino acid deleted truncated mutant CSD polypeptide (Δ101CSD) to HO-1. Primary AMs were isolated from rats, when cell fusion reached 80％, they were synchronized with serum-free medium and divided into five groups: no treatment was given to the blank control group; LPS group was treated with 100μg/L LPS for 16 hours;LPS+ hemin group was treated with 100μg/L LPS and 20μmol/L hemin for 16 hours; wild-type CSD polypeptide+ LPS+hemin group was pretreated with 10μmol/L wild-type CSD polypeptide 6 hours before LPS treatment; Δ101CSD+ LPS+hemin group was pretreated with 10μmol/L Δ101CSD polypeptide 6 hours before LPS treatment. After treatment for 16 hours, the co-localization between caveolin-1 (Cav-1) and HO-1 was displayed by confocal microscope; the mRNA expressions of inflammatory cytokines interleukin-1β (IL-1β) and monocyte chemoattractant protein-1 (MCP-1) and M1/M2 polarization cytokines tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), leukocyte differentiation antigen 206 (CD206) and IL-10 were determined by real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-qPCR); the HO-1 activity and nitric oxide (NO) production were determined by spectrophotometry.Results Bioinformatics analysis showed: both wild-type CSD and Δ101CSD peptides could bind to HO-1, and there was no significant difference in the binding ability between the two peptides, but the deletion of 101 Arg resulted in the disappearance of part of the binding region between Δ101CSD and HO-1. The results of laser confocal microscopy showed: the expressions of Cav-1 and HO-1 were lowed in the blank control group, and Cav-1 was bound to HO-1 in LPS group and LPS+ hemin group. Both wild-type CSD and Δ101CSD peptides pretreatment could significantly reduce the binding of HO-1 to Cav-1 induced by LPS. HO-1 activity analysis showed: after LPS stimulation, the activity of HO-1 was significantly higher than that of the blank control group; the activity of HO-1 induced by LPS was increased by hemin; after pretreatment with two kinds of CSD peptides, the activity of HO-1 was further increased, and the effect of wild-type CSD peptide was more significant, which showed a statistically significant difference as compared with that of LPS+ hemin group (pmol·mg-1·h-1: 3683±266 vs. 2408±132,P < 0.05). RT-qPCR results showed: LPS could induce elevation of cytokines and M1 markers and decrease of M2 markers, while hemin could inhibit LPS-induced inflammatory response and M1/M2 phenotypic polarization. Compared with LPS+ hemin group, after pretreatment with wild-type CSD peptide, the levels of inflammatory factors in AMs were decreased, and the mRNA expression levels of TNF-α and iNOS, M1 markers, were decreased [TNF-α mRNA (2-??Ct): 6.82±0.05 vs. 8.70±0.24, iNOS mRNA (2-??Ct): 331.50±32.05 vs. 506.70±0.10, bothP < 0.05], and IL-10 mRNA expression level was increased (2-??Ct: 269.09±6.54 vs. 119.05±3.30,P < 0.05). The deletion of 101 site partially weakened the inhibitory effect of CSD peptides on inflammatory factors and only reduced the expression of iNOS mRNA (2-??Ct: 429.11±8.92 vs. 506.70±0.10,P < 0.05), indicating that its ability to transform AMs from M1 phenotype to M2 phenotype was poor. The two peptides had no effect on the expression of CD206.Conclusion Wild-type CSD had beneficial effects of anti-inflammation by reducing Cav-1 binding to HO-1 induced by LPS, restoring the HO-1 activity and driving M2 phenotype in alveolar macrophages.

Objective: To explore the application and effect of the cancer case management led by cancer case managers in the whole processing management of nasopharyngeal carcinoma (NPC) patients. Methods: A randomized controlled study was designed. 510 patients with nasopharyngeal carcinoma were randomly divided into two groups: the observation group (255 cases) and the control group (255 cases). The observation group adopted the case management led by cancer case managers, and the control group adopted the cancer case management. To evaluate the rate of seeing a doctor, the implementation rate of the treatment plan and the rate of the first follow-up visit between the two groups. M.D. Anderson symptom Inventory-head-neck (MDASI-H&N) was used to evaluate the symptom disturbance (the day of hospitalization, the period of radiotherapy and chemotherapy, 1 months after discharge and 6 months after discharge). Results: The treatment rate was 90.2% (230/255) in the observation group, 78.04% (199/255) in the control group, The rate of implementation of established treatment plans 99.57% (229/230) in the observation group and 90.95% (181/199) in the control group. The first follow-up rate was 98.70% (227/230) in the observation group and 84.42% (168/199) in the control group. The difference was statistically significant (Z=19.768, 15.207, 7.042, P < 0.01). In the observation group, the average value of symptom disturbance, the average severity of symptom distress and the average degree of symptom disturbance in 3 times (the period of radiotherapy and chemotherapy, 1 months after discharge and 6 months after discharge) were (3.00±0.95) , (2.43±0.16) , (2.03±0.34) , (2.95±0.97) , (2.46±0.12) , (2.11±0.16) , (2.89±0.46) , (2.41±0.33) , (1.99±0.16) ; Significantly lower than the control group (3.69±1.51) , (2.82±0.23) , (2.42±0.13) , (3.88±1.39) , (2.87±0.34) , (2.54±0.22) , (3.61±0.75) , (2.72±0.42) , (2.38±0.17) , the difference has the statistical significance (t=-21.152—10.372, P < 0.01). Conclusion The case management led by cancer case manager can effectively improve the rate of seeing a doctor, the rate of completion of the plan and the rate of the first visit, and ensure the patients to receive effective, standard and full treatment in time. In addition, the case management can effectively improve the symptoms of patients and promote their early return to the community.

Objective To investigate the clinical outcomes of subxiphoid video-assisted thoracoscopic thymectomy for myasthenia gravis. Methods The clinical data of the 85 patients undergoing video-assisted thoracoscopic thymectomy for myasthenia gravis in Department of Cardiothoracic Surgery, Huashan Hospital affiliated to Fudan University between January 2014 and July 2016 were studied. Subxiphoid approach video-assisted thoracoscopic thymectomy (SXVT) and through traditional unilateral approach video-assisted thymectomy (TVAT) were compared. The clinical outcomes of SXVT and TVAT were compared. Results There was no surgical death and no statistical difference between the two groups in drainage time, postoperative volume of drainage, postoperative hospital stay and bleeding volume during operation (P>0.05). However, the acute chest pain after surgery, as well as the postoperative chest pain, and operative time were less in the the SXVT group than that in the TVAT group (P<0.05). Conclusion SXVT for myasthenia gravis is safe and executable. It can alleviate intercostal neuralgia and abnormal chest wall feeling. And it should be considered in the treatment of myasthenia gravis.
