In order to better understand the clinical manifestation of systemic lupus erythematosus (SLE) with intracranial hypertension syndrome (IHS), we analyzed the clinical features and treatment of a typical SLE patient with IHS. SLE is one of the most unpredictable autoimmune diseases involving multiple organ systems that is defined clinically and associated with antibodies directed against cell nuclei. IHS is an uncommon manifestation of neuropsychiatric SLE (NPSLE) and is characterized by an elevated intracranial pressure, papilledema, and headache with occasional abducens nerve paresis, absence of a space-occupying lesion or ventricular enlargement, and normal cerebrospinal fluid chemical and hematological constituents. IHS has been reported in a few sporadic cases in patients with SLE worldwide, but rarely has been reported in China. In this study, a 34-year-old female SLE patient with IHS was reported and pertinent literature reviewed. The clinical presentation, image logical features, and investigatory findings were discussed.

AIM: To investigate the expression of tissue factor(TF) induced by oxidized high density lipoprotein(oxHDL) in human umbilical vein cell line,ECV304,and the related mechanisms.METHODS: Four main groups were designed: the negative,the positive(ECV304 with histamine),the HDL group and the oxHDL group.Quantitative real-time polymerase chain reaction(RQ-PCR) and Western blotting were used to detect the expression level of TF.The specific inhibitors of MAPKs,SP600125(c-jun terminal NH2 kinase,JNK),SB203580(p38 MAP kinase,p38 MAPK),PD98059(extracellular signal-regulated kinase,ERK1/2) were used to investigate the underlying mechanisms.RESULTS: The TF expression in normal ECV304 cell line was not detected.Histamine administration resulted in a significant expression of TF in ECV304 cell line,with strongest effect after 1 h co-incubation at concentration of 1?10-5 mol/L histamine(about 4.8-fold higher expression of TF compared with that of 1?10-9 mol/L histamine).Expression level of TF was detected after stimulated with oxHDL in dose-and time-dependent manners.The highest expression of TF mRNA was found at 20 mg/L oxHDL and 6 h co-incubation,with 1.8-fold and 5.3-fold increase in TF expression,respectively,compared with that at 10 mg/L oxHDL and 2 h co-incubation.20 mg/L oxHDL also caused an apparent augmentation of TF protein expression,about 1.5-fold higher compared with that stimulated by 40 mg/L oxHDL.HDL co-incubation did not cause a detectable expression of TF protein.The mRNA levels of TF in ECV304 cell line induced by oxHDL were decreased by 95.0%,81.0%,87.0%,respectively(all P

Objective To evaluate the effect of ultrasound-guided erector spinae plane block combined with general anesthesia on early postoperative outcome in patients undergoing video-assisted thoracoscopic pulmonary lobectomy.Methods Eighty-five patients of both sexes,aged 18-64 yr,with body mass index of 18-24 kg/m2,of American Society Anesthesiologists physical status Ⅱ or Ⅲ,undergoing elective video-assisted thoracoscopic pulmonary lobectomy,were divided into 2 groups using a random number table method:general anesthesia group (group GA,n =43) and ultrasound-guided erector spinae plane block combined with general anesthesia group (group ESP+GA,n =42).Ultrasound-guided erector spinae plane block was performed after induction of general anesthesia,0.5％ ropivacaine 20 ml was injected in group ESP+GA,and 0.9％ normal saline 20 ml was injected in group GA.Both groups received patient-controlled intravenous analgesia with sufentanil after surgery.Tramadol was intramuscularly injcted as resue analgesic when visual analog scale score＞3.Quality of Recovery-40 questionnaire was used to assess the early postoperative quality of recovery at 1 day before surgery and 1 and 2 days after surgery.The consumption of intraoperative remifentanil and postoperative sufentanil,requirement for rescue analgesics and occurrence of postoperative adverse reactions were recorded.Results Compared with group GA,the Quality of Recovery-40 questionnaire scores were significantly increased at 1 and 2 days after surgery,the consumption of intraoperative remifentanil and postoperative sufentanil was reduced,and the requirement for rescue analgesics and incidence of nausea and vomiting were decreased in group ESP+GA (P＜0.05).Conclusion Ultrasoundguided erector spinae plane block combined with general anesthesia can promote early postoperative outcome in patients undergoing video-assisted thoracoscopic pulmonary lobectomy.

Objective:To study the expression of GATA3 and bcl-11b in peripheral T-cell lymphoma (PTCL) and their correlation with clinicopathological features.Methods:The Oncomine and GEO databases were used for analyzing the expression levels of GATA3 and bcl-11b mRNA in PTCL. Immunohistochemistry was used to detect the expression of GATA3 and bcl-11b proteins in 127 cases of PTCL diagnosed at Shanxi Provincial Cancer Hospital from January 2010 to June 2020, as well as 40 cases of lymph node with reactive hyperplasia.Results:The data in Oncomine and GEO databases showed that the expression of GATA3 and bcl-11b mRNA in PTCL was lower than that in normal tissues ( P<0.05). Immunohistochemistry showed that the positive rates of GATA3 in PTCL and lymph nodes with reactive hyperplasia were 60.6% (77/127) and 85.0% (34/40, P<0.05), respectively. The expression rates of bcl-11b in PTCL and lymph nodes with reactive hyperplasia were 55.1% (70/127) and 75.0% (30/40, P<0.05), respectively. The expression of GATA3 was related to the pathological classification of the patients with PTCL, and was inversely related to the Ann Arbor stage of the patient, while the expression of bcl-11b was inversely correlated with the IPI score of the patient ( P<0.05). The expression of GATA3 and bcl-11b was related to the patients′ age, gender, LDH level, and B symptoms. Other clinicopathological characteristics were irrelevant. Spearman correlation analysis shows that the expression of GATA3 protein was associated with that of bcl-11b protein in PTCL. Conclusion:GATA3 and bcl-11b are closely related to the prognosis of PTCL, and may be important factors involved in the occurrence and development of PTCL.

Multidrug resistance (MDR) is one of the main causes leading to the failure in cancer treatment. Differential proteins between esophageal squamous cell carcinoma (ESCC) cell line EC9706 and its cisdiamminedichloroplatinum (CDDP)-resistant subline EC9706/CDDP revealed by quantitative analysis may provide deeper insights into the molecular mechanisms of MDR implicated in ESCC. EC9706/CDDP was generated by exposure of its parental sensitive EC9706 to a step-wise increase of CDDP concentration during EC9706 cultivation. The stable isotope labeling with amino acids in cell culture (SILAC) was used to label EC9706 and EC9706/CDDP with heavy and light medium, separately. Mixed peptides derived from EC9706 and EC9706/CDDP were analyzed by high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS/MS) and subsequently subjected to bioinformatics analysis to identify differential proteins between EC9706 and EC9706/CDDP. Compared to parental EC9706, EC9706/CDDP manifested phenotypes of slow proliferation, cell pleomorphology, atypia and increased resistant-index 3.23. Seventy-four differential proteins identified in the present study belongs to various families with multiple functions, such as cytoskeleton (20%), energy metabolism (11%), transcription regulation and DNA repair (11%), redox homeostasis (9.5%), protein biosynthesis and mRNA processing (12%), ribosome constituent (8.1%), molecular chaperone (8.1%), immunity/inflammation (5.4%), intracellular transport (5.4%) and nucleosome assembly (2.7%), which indicated that development of MDR is a complicated process involving dysregulation of multiple molecules and pathways. The data is of great value for in-depth elucidation of molecular mechanisms of the MDR implicated in ESCC and may represent potential molecular targets for future therapeutic development.

Objective To investigate the expressions of programmed death-ligand 1 (PD-L1) and PD-L2 and phosphorylated protein kinase B (p-AKT) in diffuse large B-cell lymphoma (DLBCL) patients and their correlations with clinicopathological features and prognosis. Methods A total of 68 paraffin-embedded specimens of DLBCL patients diagnosed in Shanxi Provincial Cancer Hospital with detailed follow-up record from January 2010 to December 2012 were included in the study. The expressions of PD-L1, PD-L2 and p-AKT proteins in DLBCL were detected by using immunohistochemistry (IHC). Results The positive rate of PD-L1 protein in DLBCL patients was 22.1％ (15/68), which was related to germinal center B-cell (GCB) subtype or not (χ2= 5.591, P= 0.018), clinical stage (χ2= 3.969, P= 0.046), international prognostic index (IPI) grades (χ2=4.178, P=0.041) and treatment remission rate (χ2=6.587, P=0.010). The positive rate of PD-L2 protein in DLBCL patients was 14.7％ (10/68), which was related to extranodal metastasis or not (χ2=6.772, P= 0.009). The positive rate of p-AKT for DLBCL patients was 61.8％ (42/68), which was correlated with age (≥60 years old) or not (χ2=6.227, P=0.013), Eastern Cooperative Oncology Group (ECOG) grades (χ2=4.005, P=0.045), B symptoms (χ2=10.187, P=0.001) and treatment remission rate (χ2=4.096, P=0.043). Univariate survival analysis showed that the overall survival (OS) rate and progression free survival (PFS) rate of PD-L1 protein positive expression group were lower than those of PD-L1 protein negative expression group (both P< 0.05). In the patients with non-GCB subtype, OS rate and PFS rate of PD-L1 protein positive expression group were lower than those of PD-L1 protein negative expression group (both P<0.05). p-AKT protein positive expression group had poorer OS rate and PFS rate compared to p-AKT negative expression group (both P< 0.05). Correlation analysis showed that PD-L1 protein expression was correlated with PD-L2 and p-AKT proteins expressions (r= 0.380, P= 0.001;r= 0.273, P= 0.025). The prognosis was worse when p-AKT and PD-L1 proteins was co-expressed (P< 0.05). Multivariate analysis suggested high expressions of PD-L1 and p-AKT proteins were independent prognosis risk factors in DLBCL (both P<0.05). Conclusions The expressions of PD-L1 and p-AKT proteins may be involved in the occurrence and development of DLBCL. Blocking PD-1 and PD-L1 access or combined blocking could provide a promising future for the clinical therapy.

OBJECTIVEThe aim of this study is to analyse the efficacy and toxicity of CEOP regimen in the treatment of non-Hodgkin's lymphoma (NHL).

METHODSFrom January 1995 to December 2000, 121 patients with NHL were treated by CEOP regimen with or without radiotherapy for the involved field. The clinical characteristics, response, toxicity and long-term survival results were analysed retrospectively.

RESULTSOf these 121 patients, 83 (68.6%) had B-cell NHL and 38(31.4%) peripheral T or NK-cell NHL; 55. 4% (67/121) had early disease (stage I or II), and 89.3% (108/121) had IPI score 0-2. The median age was 53 years (range: 7-79 yr). All patients were treated by CEOP regimen (totally, 471 cycles) with or without radiotherapy. The overall response (OR) rate in this series was 90.9% (110/121) with a complete remission (CR) rate of 71.9% (87/121); whereas the response rate of chemotherapy alone was 88.4% (107/121) with a CR rate of 67.8% (82/121). Major toxicity consisted of grade III-IV myelosuppression (11.9%), neutropenia (1.9%) and thrombocytopenia and anemia (1.1%). Alopecia was observed in 46.3%. However, cardiotoxicity was mild and reversible. Median follow-up duration in this series was 63 months (range: 2-116 months). The overall 1-, 3- and 5-year survival rate was 84.8%, 62.7% and 55.9%, respectively, with a median survival time of 85 months (2-118 months).

CONCLUSIONOur data show that CEOP regimen combined with or without radiotherapy for the involved field is effective and well tolerated by the patients with non-Hodgkin's lymphoma.
