Objective To evaluate the efficacy of Lianhua Dingchuan Tablets in bronchial asthma.Methods Fifty BALB/C mice were randomly and equally divided into control (Con) group,ovalbumin (OVA) group,dexamethasone (DEX) group,high-dose Lianhua group,low-dose Lianhua group.The mice were sensitized and challenged with OVA plus aluminium hydroxide to establish asthmatic model and were pre-treated 30 minutes before challenge.Specific airway resistance (sRaw) was used to evaluate airway hyperresponsiveness,and airway inflammatory changes were measured.ELISA and Magnetic Luminex(R) were used to quantified the levels of IL-4,IL-13 and INF-γ.Results Airway resistance significantly decreased in DEX group and High-dose Lianhua group (P＜0.05).Levels of inflammatory cells and IL-13 in BALF evidently reduced in DEX group,high-dose Lianhua group and low-dose Lianhua group (P ＜ 0.05),while IL-13 level in serum only decreased in DEX group.There was no significant changes in the levels of IL 4 and INF γ among those groups.Conclusions Lianhua Dingchuan Tablets might relieve the symptoms of asthma by reducing IL-13 level and inhibiting the airway inflammation.

Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous disease characterized by airway inflammation. Airway inflammation dominated by eosinophils (EOS) has attracted increasing attention in the occurrence and development of COPD. EOS type COPD is a special population in a large number of COPD patients. In recent years, there have been many studies on EOS type COPD, involving type 2 immune response, COPD progression and the use of glucocorticoids. This article reviews the above relationships. It is helpful to further understand EOS type COPD and provide help for the clinical diagnosis and treatment of COPD.

OBJECTIVETo explore the feasibility and safety of transanal minimal invasive or combined laparoscopy total mesorectal excision.

METHODSClinical data of 11 cases with rectal cancer undergoing transanal total mesorectal excision(taTME) in our hospital between September 2014 and May 2015 were analyzed retrospectively.

RESULTSAmong 11 patients, 3 underwent pure-taTME successfully without abdominal incision and ileostomy, whose operation time was 210, 230, 215 min respectively, while other 8 patients underwent laparoscopy-assisted taTME(hybrid-taTME) with operation time ranging from 150 to 290 (median 205) min. No patient was transferred to open operation, while larger tumors of two patients were removed from hypogastric 5 cm incision. Postoperative first day VAS score was 1 to 3(2.0±0.6), the first flatus was 6 to 70(30.2±17.3) h, hospital stay was 4 to 12(7.5±2.5) d, the blood loss was (104±127) ml and the liquid food intake was (28.3±6.3) h. Postoperative complications included 1 case of subcutaneous emphysema, 1 case of anastomotic stoma bleeding, 2 cases of dysuria, which were cured by conservative therapy. One patient developed rectovaginal fistula 20 days after operation and then underwent ileostomy. No relapse of tumor or death during follow-up.

CONCLUSIONSFor suitable rectal cancer patients, taTME or hybrid-taTME is feasible.

Objective To investigate the expression characteristics of S100 calcium binding protein P(Sl00P)and thymic stromal lymphopoietin(TSLP)in patients with breast cancer and their relationship with prognosis.Methods GEPIA database and bc-GenExMiner v4.3 were used to analyze the expression levels of S100P and TSLP in breast cancer tissues,and Kaplan-Meier Plotter was used to analyze effects of S100P and TSLP on patient prognosis.The protein interaction network analysis of S100P and TSLP were carried out by using STRING database.The co-expressed genes of S100P and TSLP were analyzed using Linked Omics database,and the role of S100P and TSLP co-expressed genes in related biological processes and signaling pathways were evaluated by gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis.The correlation between S100P and TSLP and breast cancer immunoinfiltration was analyzed by TIMER.Results The expression of S100P in breast cancer patients was significantly higher than that in normal population,and the expression of TSLP was significantly lower than that in normal population(P＜0.05).The overall survival,disease-free survival and distant metastasis-free survival of patients with high S100P expression were significantly shorter than those of patients with low S100P expression(P＜0.05).The distant metastasis-free survival of patients with high expression of TSLP was significantly longer than that of patients with low expression of TSLP(P＜0.05).The results of protein interaction showed that S100P had a strong interaction with interleukin-11,and TSLP had a strong interaction with interleukin family proteins.The co-expressed genes of S100P and TSLP were mainly responsible for biological functions such as DNA replication and immune function.TSLP was correlated with breast cancer immune cell infiltration.Conclusion S100P and TSLP can be used as biomarkers to predict the prognosis of breast cancer,and they can also help to evaluate the tumor immunoinfiltration in breast cancer patients,and TSLP could provide theoretical basis for predicting the prognosis and tumor immunotherapy in breast cancer patients.

Objective:To investigate the value of sedation in colonoscopy.Methods:A retrospective cohort study of colonoscopy procedures was performed in our institution. Inclusion criteria: (1) colonoscopy procedures were performed by well-trained gastrointestinal surgeons our institution; (2) medical records were complete and colonoscopy was documented properly by notes, videos, photographs, and traceable pathological reports. Those with incomplete records or performed in other institution were excluded. According to above criteria, clinical data of 49 057 cases of clinic and hospitalization receiving diagnostic or therapeutic colonoscopyat Department of Gastric and Colorectal Surgery, Daping Hospital from July 2007 to February 2017 were collected. Among them, there were 24 638 (50.2%) males and 24 419 females, with mean age of (50.6±14.1) (4 to 98) years. Based on the application of sedation during colonoscopy, patients were divided into the sedation group (39 412 cases, 80.3%) and the non-sedation group (9 645 cases, 19.7%). Clinical characteristics of two groups were compared.Results:The sedation rate increased from 45.6% (369/810) to 94.8% (917/967) from 2007 to 2017. As compared to non-sedation group, a higher proportion of females [51.0% (20 095/39 412) vs. 44.8% (4 324/9 645), χ 2=117.422, P<0.001] and younger median age (50.0 years vs. 51.0 years, Z=-4.774, P<0.001) were found in the sedation group, whose differences were statistically significant. In all the 9645 cases in the non-sedation group, about 5.5% (534) of them terminated the examination because of unbearable discomfort, including 244 (4.6%) males and 290 (6.7%) females (χ 2=20.522, P<0.001). Among all the screening population who were ≥50 years old, there was no significant difference in the polyp detection rate (PDR) between the sedation group and the non-sedation group [26.7% (4 737/17 753) vs. 27.4% (1 093/3 984), χ 2=0.937, P=0.330]. The cecal intubation rate (CIR) in the sedation group was significantly higher than that in the non-sedation group [(85.2% (14 422/16 933) vs. 76.1% (2 803/3 682), χ 2=180.032, P<0.001]. Five cases in the sedation group developed iatrogenic colonic perforation (ICP), with none in the non-sedation group. Conclusions:The application of sedation in colonoscopy is increasingly popular. Sedation can significantly improve CIR in colonoscopy, while it has no positive influence on PDR. Meanwhile, sedation increases the medical expense and may result in higher ICP rate.
