Objective:To investigate the clinical characteristics and prognosis of patients with cutaneous intravascular large B-cell lymphoma (IVLBCL).Methods:The data of 30 cutaneous IVLBCL published between January 1989 and May 2019 in China were systematically reviewed. The clinical manifestation, biochemical and imaging characteristics and diagnostic features of patients were summarized, and then the survival of different groups was also analyzed.Results:The median onset age was 61.5 years old (25.0-83.0 years old), and there were 22 (73.3%) females. All 30 patients presented with cutaneous lesions. Initial symptoms showed cutaneous lesions in 16 (53.3%) patients; and B symptom, respiratory symptoms or central nervous system (CNS) occurred in 14 (46.7%) patients with late cutaneous lesions. Cutaneous lesions were heterogeneous, and 76.7% (23/30) lesions located in lower abdomen and proximal limbs. And 76.2% (16/21) were positive in image examination, and 78.3% (18/23) had two or more extranodal organs invasion. The median time from onset to visit was 2.5 months (0.4-24.0 months), and clinical misdiagnosis rate was 56.7%(17/30). All IVLBCL patients were confirmed by biopsy, including 6 cases (27.3%, 6/22) of bone marrow involvement, 1 case (3.3%) of hemophagocytic syndrome-associated variant, and 29 cases (96.7%) of classical variant. Finally, 81.8% (18/22) patients received anthracycline-based combined chemotherapy. Compared with non-chemotherapy group, the median OS time of chemotherapy group was prolonged [11.0 months (2.0-60.0 months) vs. 2.0 months (0.7-24.0 months), P = 0.002]. Patients with CNS symptoms had shorter median OS time compared with patients without CNS symptoms [2.0 months (0.7-6.0 months) vs. 11.0 months (1.0-60.0 months), P < 0.01]. The median OS time in the group of cutaneous lesions as initial symptom combined with other symptoms was longer than that in group of late cutaneous lesions and other symptoms as initial symptom [unreached (2.0-60.0 months) vs. 3.0 months (1.5-24.0 months), P = 0.032]. Conclusions:Cutaneous IVLBCL is a rare disease with atypical clinical characteristics in China. Prompt attention and biopsy in time will be helpful for early diagnosis. Accompanied with CNS symptoms suggests poor prognosis; and timely chemotherapy can improve the prognosis of the patients.

Observation indicators: (1) follow-up; (2) risk factors for anastomotic leakage after laparoscopic LAR; (3) establishment of risk assessment scoring model for anastomotic leakage after laparoscopic LAR. Follow-up was conducted by outpatient examination or telephone interview. Patients were followed up at 1 week after discharge or 1 month after the operation to detect the anastomotic leakage. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the chi-square test and multivariate analysis was conducted usong the Logistic regression model. The area under curve of receiver operating characteristic curve was used to estimate the efficiency of detecton methods. The maximum value of the Youden index was defined as the best cut-off value. Results:(1) Follow-up: 539 patients were followed up at postoperative 1 week and 1 month. During the follow-up, 79 patient had anastomotic leakage, with an incidence of 14.66%(79/539). Of the 79 patients, 39 cases were cured after conservative treatment, 40 cases were cured after reoperation (ileostomy or colostomy). (2) Risk factors for anastomotic leakage after laparoscopic LAR. Results of univariate analysis showed that sex, age, body mass index, smoking and/or drinking, tumor diameter, diabetes mellitus, hemoglobin, albumin, grade of American Society of Anesthesio-logists (ASA), neoadjuvant chemoradiotherapy, distance from anastomotic level to dentate line, the number of pelvic stapler, reinforced anastomosis, volume of intraoperative blood loss, placement of decompression tube, preservation of left colic artery, operation time and professional doctors were related factors for anastomotic leakage after laparoscopic LAR ( χ2=14.060, 4.387, 5.039, 4.094, 17.488, 33.485, 25.066, 28.959, 34.973, 34.207, 22.076, 13.208, 16.440, 17.708, 17.260, 4.573, 5.919, 5.389, P<0.05). Results of multivariate analysis showed that male, tumor diameter ≥3.5 cm, diabetes mellitus, hemoglobin <90 g/L, albumin <30 g/L, grade of ASA ≥Ⅲ, neoadjuvant chemoradiotherapy, distance from anastomotic level to dentate line <1 cm, the number of pelvic stapler ≥3, non-reinforced anastomosis, volume of intraoperative blood loss ≥100 mL and no placement of decom-pression tube were independent risk factors for anastomotic leakage after laparoscopic LAR ( odds ratio=2.864,3.043,12.556,7.178,8.425,12.895,8.987,4.002,3.084,4.393,3.266,3.224,95% confidence interval as 1.279?6.411, 1.404?6.594, 4.469?35.274, 2.648?19.459, 2.471?28.733, 4.027?41.289, 3.702?21.777, 1.746?9.171, 1.365?6.966, 1.914?10.083, 1.434?7.441, 1.321?7.867, P<0.05). (3) Establishment of risk assessment scoring model for anastomotic leakage after laparoscopic LAR. based on the results of univariate analysis, clinicopathological factors with χ2>20, χ2>10 and ≤20 or χ2≤10 were defined as scoring of 3, 2, 1, respectively. The cumulative clinicopatho-logical factors scoring ≥6 was defined as an effective evaluating indicator for postoperative anastomotic leakage. The risk assessment scoring model (6-321) for anastomotic leakage after laparoscopic LAR was established. The cumulative value ≥6 indicated high incidence of anastomotic leakage, and the cumulative value <6 indicated low incidence of anastomotic leakage.

The risk assessment scoring model (6-321) is established according to the above results.The cumulative value ≥6 indicates high incidence of anastomotic leakage and the cumulative value <6 indicates low incidence of anastomotic leakage.

Group 2 innate lymphoid cells (ILC2s) are the "mirror cells" of Th2 cells. Although the total cell number of ILC2s is far less than that of CD4⁺ Th2 cells in the body, the activated ILC2s have a more powerful biological activity than CD4⁺ Th2 cells and can rapidly enhanced Th2-cell inflammatory reaction. It plays an important role in the pathogenesis of allergic respiratory diseases. The transmitters that activate ILC2s include inflammatory cytokines (IL-33, IL-25, TSLP, IL-4, IL-9), lipid transmitters (prostaglandins, leukotrienes), and other activating transmitters (ICOS, Complement C3a, neuropeptide receptor, vasoactive intestinal peptide and calcitonin gene-related peptide, etc). Activated ILC2s produce large amounts of IL-4, IL-5, IL-9, IL-13, and amphiregulin and other inflammatory mediators, and induce airway hyperresponsiveness, mucus secretion and airway remodeling and other respiratory allergic reactions. Therefore, respiratory allergic diseases, especially steroid-dependent asthma, could be treated potentially by inhibiting the activation of ILC2s. Hereby, we summarized the immunobiology of ILC2s, the initiation of ILC2s in allergic inflammation, the relationship between ILC2s and respiratory allergic diseases, and the recent advances in biological agents targeted by ILC2s.

Objective : To analyze circular RNA (circRNA) expression profiles in oral squamous cell carcinoma (OSCC) and its clinical significance. Methods : The expression of circRNA was detected with circRNA microarray assay in three samples of OSCC tumor and matched adjacent tissues. Quantitative real-time PCR (RT-qPCR) was used to verify the expression of circRNA in 45 pair OSCC tissues and normal adjacent tissues. The relationship between the expression of circRNA and the clinicopathological characteristics of OSCC was analyzed. circRNAs/miRNAs interaction were predicted using Arraystar' s home-made miRNA target prediction software. Results : 155 circRNAs were differentially expressed between the OSCC tissues and matched adjacent tissues, of which 45 circRNAs were up-regulated and 110 circRNAs were down-regulated in OSCC tissues (fold changes ≥1.5 and P < 0.05). In the selected three circRNAs that were most significantly upregulated or downregulated in OSCC, the RT-qPCR results showed that hsa_circ_0001874, hsa_circ_0001971 and has_circ_0067934 were increased, while hsa_circ_0000520, hsa_circ_0023944 and hsa_circ_0000140 were decreased in OSCC tissues versus normal adjacent tissues (P < 0.001). The results were generally consistent with the microarray data. Among the circRNA expression profiles in OSCC, the up-regulation of hsa_circ_0001874 was the highest and the expression of hsa_circ_0001874 was significantly correlated with TNM stage and tumor grade. The result of Arraystar' s home-made miRNA target prediction software indicated that miR-103a-3p, miR-107, miR-593-5p, miR-661 and miR-662 may be potential target genes of hsa_circ_0001874. Conclusion The differentially expressed circRNAs in OSCC tissues and normal adjacent tissues were identified, and these dysregulated circRNAs and their potential target gents may play important roles in the development of OSCC.

Objective: To explore the expression and clinical significance of circular RNA circHIPK3 in oral squamous cell carcinoma (OSCC), analyze the effect of circHIPK3 on the proliferation of OSCC cells. Methods: The expression of circHIPK3 in OSCC tissues, adjacent non-cancerous tissues and OSCC cell lines were detected by quantitative real-time polymerase chain reaction (qPCR). The correlations between the expression of circHIPK3 in OSCC tissues and the clinicopathological features were analyzed as well. circHIPK3-specific siRNA si-circHIPK3 and negative control siRNA si-NC were designed and synthesised and used to transfect CAL27 and SCC15 cells respectively. The proliferation capacity of CAL27 and SCC15 cells after transfection with si-circHIPK3 was detected by CCK-8 assay. The expression of miR-124 in OSCC was detected by qPCR, and the correlation between expression of circHIPK3 and the expression of miR-124 was analyzed. Using qPCR to detect the expression of miR-124 in CAL27 and SCC15 cells after transfection with si-circHIPK3 and si-NC respectively. Furthermore, using CCK-8 assay to detect the proliferation capacity of CAL27 and SCC15 cells after transfection with si-NC, si-circHIPK3, miR-124 mimic, si-circHIPK3+miR-124 inhibitor. Results: The expression of circHIPK3 in OSCC tissues [2.23 (1.86, 3.00)] was significantly higher than that of the adjacent non-cancerous tissues [1.05 (0.85, 1.26)] (U=1 094, P=0.000). The expression of circHIPK3 in CAL27 (3.02±0.51) and SCC15 cells (3.16±0.75) was higher than those of human normal oral keratinocytes (hNOK) (1.26±0.30) (P=0.000). The expression of circHIPK3 was found to be closely associated with TNM stage (P<0.05) and tumor grades (P<0.05). Knockdown of circHIPK3 can inhibit proliferation of CAL27 and SCC15 cells (P<0.05). The expression of miR-124 in OSCC tissues (0.61±0.35) was significantly lower than that in adjacent non-cancerous tissues (1.13+0.39) (t=-5.36, P<0.05). Correlation analysis showed that the expression of circHIPK3 in OSCC was negatively correlated with the expression of miR-124 (r=-0.767, P<0.001). Moreover, down-regulation of miR-124 rescued the phenotype induced by knockdown of circHIPK3. Conclusions The expression of circHIPK3 in OSCC was increased, and silencing of circHIPK3 expression can inhibit the proliferation of OSCC cells. Our results suggest that circHIPK3 may play a key role in the occurrence and development process of OSCC through the regulation of miR-124 expression.
