Psoriasis has complex causes, is difficult to treat, prone to recurrent attacks, and persists for a long time, greatly affecting their health and quality of life. This article reviews the current status, influencing factors and assessment tools of self-management in psoriasis patients, aiming to improve the understanding and knowledge of self-management among medical and nursing staff, and provide meaningful references for the selection of self-management assessment tools and intervention research for psoriasis patients.

Objective:To evaluate the long-term efficacy of laparoscopic-assisted natural orifice specimen extraction surgery (NOSES) colectomy using Cai tube for treating left-sided colorectal cancer.Methods:This was a randomized controlled trial. Inclusion criteria were as follows: preoperative pathological diagnosis of left-sided colorectal adenocarcinoma (rectal, sigmoid colon, descending colon, or left transverse colon cancer with the caudad margin ≥8 cm from the anal margin); preoperative abdominal and pelvic computed tomography (or magnetic resonance imaging) showing maximum tumor diameter <4.5 cm; and BMI <30 kg/m 2. Patients with synchronous multiple primary cancers or recurrent cancers, a history of neoadjuvant chemoradiotherapy, preoperative evidence of significant local infiltration, distant metastasis, or complications such as intestinal obstruction and intestinal perforation, or who were not otherwise considered suitable for laparoscopic surgery were excluded. A random number table was used to randomize sequential patients to NOSES surgery using Cai tube (non-assisted incision anal sleeve: patent number ZL201410168748.2) (NOSES group) or traditional laparoscopic-assisted surgery (CLS group). Relevant clinical data of the two groups of patients were analyzed, the main outcomes being disease-free survival, overall survival, overall recurrence rate, and local recurrence rate 5 years after surgery. Results:Patients in both study groups completed the surgery successfully with no requirement for additional surgery. After mean 70 (7–83) months postoperative follow-up, the 5-year overall postoperative survival in the NOSES and CLS groups was 90.0% and 83.3%, respectively ( P=0.455); disease free survival was 90.0% and 83.3%, respectively ( P=0.455); overall recurrence rate 6.6% and 10.0%, respectively ( P=0.625); and local recurrence rate both were 3.3% ( P=0.990), respectively. None of these differences was statistically significant. Conclusions:NOSES and CLS have similar long-term efficacy, and NOSES deserves to be used in clinical practice.

By using Doppler sensor and pressure sensor, the cerebrovascular stroke detector can be used to measure the blood flow velocity and blood pressure of the carotid artery. In this study, a variety of signal conversion and isolation processing techniques are proposed for processing and feature extraction of the output signals from the sensors. Finally, effective signal output waveforms that can be used to evaluate the cerebrovascular hemodynamics index (CVHI) are obtained, and the sound signal outputs that can reflect the change characteristics of blood flow velocity and blood pressure signals are generated, which realizes the application functional requirements of the detector.

OBJECTIVETo explore the feasibility of laparoscopic-assisted natural orifice specimen extraction radical left colectomy.

METHODSRetrospective analysis was performed on clinicopathological dada of 15 colorectal patients who were treated by laparoscopic-assisted anal specimen extraction radical left colectomy with self-developed surgical instrument Cai tube between January and September in 2014. Tumor location included descending colon (n=3), the junction of descending colon and sigmoid colon (n=2), the sigmoid colon (n=6) and upper rectum (n=4). Clinical efficacy of patients was observed.

RESULTSThere were no perioperative deaths or postoperative complications, such as anastomotic bleeding or leakage. The median operation time was 257 (range 103-337) min, median blood loss was 50(range 20-200) ml, median time to first flatus was 3 (range 1-5) d and median hospital stay was 14 (range 11-21) d. All the patients had good quality of life and normal defecation function without tumor recurrence or metastasis after 1-8 months of follow-up.

CONCLUSIONLaparoscopic-assisted anal specimen extraction radical left colectomy is safe and feasible.

Objective To investigate the expression of ASK1 and PRKCD in the process of monocyte differentiation, and explore their role in functional changes of hypersplenism spleen macrophages (MΦ) in portal hypertension (PH). Methods U937 cells were stimulated to differentiate into monocyte/macrophage-like cells by cultivation in PMA and the mRNA expressions of ASK1 and PRKCD were detected by q-PCR and the changes of protein expression were identified by western blot analysis. The secretion of phagocytose related cytokines such as IL-10 and TNF-a were tested by ELISA, and the function of the macrophage-like cells were studied by chicken red blood cell phagocytose test. Results The expressions of PRKCD and ASK1 mRNA were gradually decreased along with the cell differentiation, while the secretion of TNF-αwas increased, IL-10 secretion reached a maximum at 24 h after PAM stimulation, and then gradually fell. The expression of ASK1 and p-ASK1 were rapidly increased compared with the non-stimulated U937 cells, while the expression of PRKCD and p-PRKCD were sightly declined. The phagocytose test show that U937 cells induced with PMA were able to swallow the chicken red blood cell.Conclusion Up-regulated protein expression of ASK1 and p-ASK1 and down-regulated protein expression of PRKCD and p-PRKCD in the process of PMA induced monocyte differentiation, are consist with the expression changes of splenic macrophage phagocytosis in hypersplenism, which leads to increased activity of MΦ.

OBJECTIVETo investigate the expressions of extracellular signal-regulated kinase (ERK) and the BH3-only subgroup of Bcl-2 related proteins (Bim) in multidrug-resistant hepatocellular carcinoma (HCC) cells and their association with drug resistance in the cells.

METHODSThe multdrug-resistant HepG-2 cell line was established by treatment with gradually increasing doses of ADM. CCK-8 assay was used to determine the drug sensitivity of the cells, and the expressions of MRP-1, P-gp, ERK1, ERK2, ERK5, and Bim were detected with Western blot. Bim mRNA expression level was measured using quantitative real-time PCR.

RESULTSThe drug resistance indices to ADM, 5-FU and CDDP was 6.8, 4.10, and 4.5 in HepG-2/ADM cells, respectively. The drug-resistantcells showed marked up-regulation of MRP-1, P-gp, ERK1, ERK2 and ERK5 with down-regulated phosphorylated ERK2 protein expression but no significant changes in phosphorylated ERK1 protein expression to result in a decreased ratio of P-ERK1/2 and P-ERK1/2. Bim mRNA and protein expressions were both decreased in HepG-2/ADM cells.

CONCLUSIONERK and Bim are related to multidrug resistance in HepG-2/ADM cells.
