Objective To evaluate the influence of chronic urticaria on the quality of life in patients by the DLQI, and to assess the factor structure and reliability of the DLQI. Methods The DLQI (Chinese version) was used to evaluate the quality of life of outpatients with CU. The reliability and factor structure of the DLQI were evaluated by reliability analysis and factor analysis. Results Eighty-five patients were asked to complete the DLQI and 13 patients were excluded for other complicated disorders or unanswered items in the DLQI. The mean age was 33.43 ± 0.90 years in the 72 patients with a median clinical course of 6 months. The DLQI score, which varied from 1 to 23 with an average of 9.46 ± 0.61, was uncorrelated to the patients' age,sex, or clinical course of CU (all P > 0.05). The impact of CU was observed mainly on the "synptoms and feeling" (50%), followed by "work and study" (40.67%). Factor analysis indicated that there were two dimensions with eigenvalues greater than 1.0, accounting for 53.7% of the variances. Reliability analysis showed that the Cronbach's α value was 0.836, and reached 0.849 if the item 1 in the DLQI was deleted. An analysis of variance showed that the F value was 31.88 (P < 0.01 ), and Hotelling T2 test yielded an F value of 29.87 (P <0.01 ). Conclusions CU has a moderate impact on the quality of life in patients. DLQI can be applied to the evaluation of quality of life in patients with CU with a high reliability, but more attention should be paid to the interference from item 1 to the reliability of the assessment.

Objective To investigate the key procedures of the acute traumatic intracranial hematoma com-bined with herniation and the prognosis factors. Methods 45 cases of acute traumatic intraeranial hematoma com-bined with herniation from February 1997 to June 2008 were admitted in our hospital. Timely establishment of effec-tive ventilation and circulation and pre-operative examination were done to all the eases. Craniotomy hematoma clean was performed in 8 cases, hematoma clean and decompressive craniectomy was canducted in 33 cases and 4 cases were not operatively treated. Results 26 eases (58%) were cured,and 19 cases (42%) died. Conclusions The key procedures of the acute tranmatie intraeranial hematoma combined with herniation is timely establishment of ef-fective ventilation and circulation, and that is effective method to prevent secondary brain injury ; removing hematoma as soon as possible,and lifting the oppression of the brain stem are the keys to rescue patients. Prognosis is closely related to the degree of primary brain injury, eonseious level before operation and the time of herniation appearance.

Objective To investigate the relationship between axillary lymph node status and molecular pathological features in breast cancer and its clinical significance. Methods A retrospective analysis was performed to study the relationship of axillary lymph node metastasis (LNM), positive lymph node (PLN), and lymph node ratio (LNR) with clinical and molecular pathology features in 300 patients with breast cancer. Results Of 300 cases of breast cancer, the positive rate of axillary LNM was 31.0% (13/42) in the Luminal A subtype of breast cancer, yielding a statistically significant difference (P < 0.05), compared with that of other molecular subtypes. Of 144 patients with positive axillary LNM , there were no significant difference of LNR and PLN between different molecular subtypes of breast cancer (P > 0.05). PLN and LNR were all negatively correlated with E-cadherin expression in breast cancer (P < 0.01 and P < 0.05, respectively), correlated with tumor size and TNM staging (P < 0.05), but not with age, menopausal status, and histological grade (P > 0.05). Conclusion The combined phenotype expression of ER, PR, HER-2, and Ki67 (molecular subtypes) are associated with the incidence of axillary lymph node metastases , and E-cadherin expression deficiency and tumor size growth promote the progression of lymph node metastases in breast cancer.

Objective To analyze the expression feature and function of microRNAs in exosomes secreted by leukemia cells (LCEX). Methods The mice leukemia cell line L1210 was taken as the example, and LCEXL1210 was obtained by isolating supernate of L1210 cells through density gradient centrifugation. MicroRNAs isolated from LCEXL1210 were analyzed by microarray analysis, compared with miRNA from L1210 cell line, and then some of miRNAs with different expression were verified by real-time PCR and were analyzed by Gene Ontology (GO) database. Results The number of miRNAs identified in LCEXL1210 was 1 044, and that in L1210 cell line was 872. The number of shared miRNAs between LCEXL1210 and L1210 cell line was 732, accounting for 70.1 % of LCEXL1210 and 83.9 % of L1210 cell line, respectively, which indicated that 70 % of LCEXL1210 was derived from the parental cells. Interestingly, 312 miRNAs in LCEXL1210 were found to be underrepresented in the parental cells, indicating their specificity in LCEXL1210. Some miRNAs were significantly highly expressed in LCEXL1210 compared with those in L1210 cell line, including miR-16-1, miR-210, miR-195 and so on, which showed that miRNAs isolated from LCEXL1210 were differentially expressed with those from the parental cells. Some differentially expressed miRNAs from LCEXL1210 were verified by real-time PCR, and then were analyzed by GO database, which demonstrated that these highly expressed miRNAs participated in the processes of various biological function and signal transduction. Conclusions MiRNAs isolated from LCEXL1210 show a high similarity to miRNAs isolated from L1210 cells, whereas of which one-third are specific. The highly expressed miRNAs participate in the processes of various biological function and signal transduction.

Objective To explore the expression of miRNA-181a (miR-181a) in patients with multiple myeloma (MM) and its effect on biological features of MM cells. Methods CD138+cells of bone marrow from 25 MM patients and 10 patients with hematological non-malignancies were purified by using immunomagnetic separation, and the expression of miR-181a in CD138+cells and MM cell lines including RPMI 8226, H929 and U266 were detected by real-time quantitative PCR. The effects of down-regulation and up-regulation of miR-181a expression on the biological characteristics of MM cells were studied with miR-181a antagomir and agomir. Results Compared with patients with hematological non-malignant diseases, the expression of miR-181a in CD138+ cells was upregulated in MM patients. Compared with CD138+ cells in hematological non-malignancies, high expressions of miR-181a were observed in RPMI 8226 and U266 myeloma cell line, while low expressions of miR-181a were observed in H929 cells. Down-regulation of miR-181a with 100 nmol/L miR-181a antagomir could inhibit the proliferation of U266 cells at 24,48 and 72 h [(67.1 ± 3.3) %vs. (50.5 ± 4.1) %, (71.5 ± 3.6) % vs. (52.3 ± 2.2) %, (78.1 ± 5.4) % vs. (69.5 ± 4.3) %, P < 0.05 respectively], whereas up-regulation of miR-181a with 100 nmol/L miR-181a agomir could significantly promote the proliferation of H929 cells at 24 h and 48 h [(21.2 ± 2.4) %vs. (38.5 ± 3.6) %, ( 61.3 ± 5.4) %vs. (82.2 ±6.9)%, P<0.01 respectively]. Cell cycle analysis showed that miR-181a antagomir made U266 cell cycle arrest in the G0/G1 phase. Meanwhile, susceptibility test results indicated that the apoptosis of U266 cells induced by doxorubicin, paclitaxel and 5-fluorouracil was increased when the proliferation of miR-181a expression was down-regulated with miR-181a antagomir. In migration assay, the data showed that down-regulation of miR-181a with miR-181a antagomir could inhibit the migration of U266 cells, and the proportion of migrated cells in the experimental group (62 ± 10) %was lower than that in the control group (89 ± 12) %(P< 0.05), whereas up-regulation of miR-181a with miR-181a agomir could improve the migration of H929 cells, and the proportion of migrated cells in the experimental group (242 ± 9) % was higher than that in the control group (98 ± 8)%(P<0.01). Conclusions The high expression of miR-181a expressed highly by MM cells may promote the proliferation, migration and drug resistance of myeloma cells, indicating that miR-181a could be an important prognostic biomarker candidate, and the application of gene silencing may improve the prognosis of MM.

OBJECTIVETo compare the perioperative complications between Ivor-Lewis approach and McKeown approach in minimally invasive esophagectomy and gastric tube reconstruction for the treatment of middle and lower thoracic esophageal cancer.
METHODSRetrospective analysis of clinical data was performed on 288 patients with middle and lower thoracic esophageal cancer who underwent completely minimally invasive esophagectomy by one surgical team in Fujian Medical University Union Hospital from December 2010 to March 2014. Among the 288 patients, 103 patients underwent combined laparoscopic and thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis using a transoral anvil(Orvil)(Ivor-Lewis group, 2-incision) and 185 patients underwent combined laparoscopic and thoracoscopic esophagectomy and cervical anastomosis(McKeown group, 3-incision). Patients were stratified by surgical approach and perioperative outcomes were compared between the two groups.
RESULTSThere were no statistical differences between two groups in intra-operative blood loss, conversion to open, extubation time, time to resume oral intake, postoperative hospital stay, the median number of lymph nodes resected. The operation time of Ivor-Lewis group was significantly shorter than that of McKeown group [(283.4±32.0) min vs. (303.6±43.7) min, P=0.003). The hospital cost of Ivor-Lewis group was significantly higher than that of McKeown group [(76 492±18 553) yuan vs. (68 923±17 331) yuan, P<0.01]. There were no statistical differences between two groups in chylothorax, delayed gastric emptying, atrial fibrillation, postoperative bleeding, admission to ICU, short-term postoperative mortality (P>0.05). The total postoperative complication morbidity of Ivor-Lewis group was significantly lower than that of McKeown group(16.5% vs. 31.4%, P<0.01). Ivor-Lewis group had lower pulmonary complication(8.7% vs. 25.9%, P<0.01), anastomotic leakage(1.9% vs. 13.0%, P<0.01), anastomotic stricture (0% vs. 4.9%, P<0.05), recurrent laryngeal nerve injury(1.0% vs. 7.0%, P<0.05).
CONCLUSIONIvor-Lewis approach is associated with less postoperative complications, but higher cost as compared to McKeown approach in the treatment of middle and lower thoracic esophageal cancer.

Objective:To explore the diagnosis, surgical methods and therapeutic effect of primary duodenal malignant tumor.Methods:The clinical data of 116 patients with primary duodenal malignant tumor from January 2010 to December 2018 were retrospectively analyzed.Results:Among 116 patients, adenocarcinoma was in 74 cases, interstitial tumor was in 25 cases, carcinoid was in 9 cases, the others was in 8 cases. Before operation, duodenoscopy was performed in 107 cases, and CT examination was performed in 76 cases. There were 57 cases of pancreaticoduodenectomy, 15 cases of duodenal segmental resection, 13 cases of subtotal gastrectomy and duodenal bulbar resection, 13 cases of duodenal partial resection, and 18 cases of palliative short circuit operation. The total incidence of postoperative complication was 31.9% (37/116), including pancreatic fistula in 8 cases (grade B 5 cases, grade C 3 cases), biliary fistula in 6 cases, abdominal infection in 5 cases, pulmonary infection in 4 cases, intestinal fistula in 3 cases, delayed gastric emptying in 3 cases, and hemorrhage in 8 cases. Four cases (3.4%) died during the perioperative period. Single factor Cox regression analysis result showed that the postoperative survival time was related to the tumor differentiation degree, operation method, tumor infiltration degree and lymphatic metastasis ( P<0.05 or <0.01); multi-factor Cox regression analysis results showed that the operation method, tumor infiltration degree and lymphatic metastasis were the independent risk factors for the postoperative survival time of patients with primary duodenal malignant tumor ( P<0.05). The patients were followed up until June 2021, and 9 cases were lost to follow-up. Kaplan-Meier survival curve analysis result showed that the postoperative overall 1-,3- and 5-year survival rates were 82.11%, 57.56% and 33.11%, respectively. Conclusions:Adenocarcinoma is the main primary malignant tumor of duodenum. Duodenoscopy and CT are the main examination methods. Radical resection is the most effective treatment for primary duodenal malignant tumor, and pancreaticoduodenectomy is the first choice. Surgical method, tumor infiltration degree and lymphatic metastasis are the independent risk factors affecting the prognosis of patients.
