Objective To study the expression and value of CXCR1 and CXCR2 on neutrophils, CD14~+ monocytes and CD3~+ T lymphocytes of peripberol blood of ankylosing spondylitis(AS)patients and to investigate the correlation between CXCR1,CXCR2 and disease activity.Methods A case control study was designed and enrolled 30 active AS,30 active rheumatoid arthritis(RA)and 30 healthy controls.The levels of CXCR1 and CXCR2 expression on neutrophils,CD3~+ T cells and CD14~+ monocytes of peripheral blood of the patients and healthy controls enrolled were measured and analyzed by flow cytometry by measuring the mean fluorescence intensity(MFI)channel.The correlations between the level of CXCR1 and CXCR2 anti disease activity or functional index of AS such as BASDAI,BASF1,ESR and CRP were analyzed.Results The MFI of CXCR1 expression on CD3~+ T lymphocytes of peripheral blood was significantly higher in AS patients (41?24)than that in RA patients(18?10)and healthy controls(19?7)(P

OBJECTIVE: To explore alcohol pharmacokinetics as well as acetaldehyde level in peripheral blood in human subjects with different ALDH2 genotypes after drinking. METHODS: Venous blood samples of 14 unrelated volunteers were collected. Polymerase chain reaction-restriction fragment length polymorphism technology was adopted for DNA extraction and ALDH2 genotyping. The volunteers were asked to drink beer at certain doses. The concentration of alcohol and acetaldehyde were assayed by headspace gas chromatography method at different time. The pharmacokinetic parameters were calculated. RESULTS: According to the results of electrophoresis, 5 people carried ALDH2*1/*1 as wild group and 9 people carried ALDH2*1/*2 as mutation group. The good linear range of alcohol and acetaldehyde were 0-1 570.7 microg/mL and 0-5.1772 microg/mL, respectively. The AUC values of alcohol and acetaldehyde and the t1/2Z value of alcohol were higher in the mutation group than that in the wild group. But the CL/F value of alcohol was lower in the mutation group than that in the wild group (P<0.05). CONCLUSION After the consumption of alcohol, alcohol and acetaldehyde metabolism in blood slow down in ALDH2*1/*2 mutation group influenced by the inhibition of enzyme activity, leading to the accumulation of acetaldehyde in peripheral blood, thus reinforcing their effects in the body.

OBJECTIVETo summarize early experience in combined thoraco-laparoscopic esophagectomy with two-field lymph node dissection for esophageal carcinoma.

METHODSA total of 150 patients with thoracic esophageal cancer who underwent combined thoracoscopic and laparoscopic esophagectomy in Union Hospital, Fujan Medical University, were enrolled in this study.

RESULTSLocations of the tumors included upper esophagus (n=14), middle esophagus (n=95), and lower esophagus (n=41). Pathological type showed squamous cell cancer (n=142) and other types of cancer (n=8). There was no intraoperative death. Conversion to open thoracotomy was required in 6 patients and conversion to open laparotomy in 2 patients. The average total operative time was( 258±45) min. The average operative thoracoscopic time was (140±33) min. The average time for gastric mobilization and neck esophagogastric anastomosis was (119±28) min. The average blood loss during the procedure was (207±130) ml. The average number of harvested lymph node with the specimen was 23.3±8.2. The tumor staging included stage I (n=39), II (n=58) and III (n=53). Postoperative complications occurred in 48(32%) patients including pneumonia (n=17), recurrent laryngeal injury (n=13), anastomotic leak (n=9), arrhythmias (n=9), chyle chest (n=5), delayed gastric emptying (n=5), ileus (n=2), volvulus (n=1), and thrombocytopenia (n=1). Two patients died postoperatively due to respiratory failure resulting from pneumonia.

CONCLUSIONThoraco-laparoscopic two-field lymph node dissection of esophageal cancer is a feasible minimally invasive approach.

OBJECTIVETo identify the effect of interleukin-8 in cell progression and invasion of human breast cancer.

METHODSHuman cytokine antibody arrays were applied to screen a panel of cytokine expression from 11 human breast cancer cell lines, and the mechanism of identified key factors involved in breast cancer progression was studied.

RESULTSProfiling of cytokine expression showed the expression of interleukin-8 was related to estrogen receptor status, metastasis and vimentin status in the 11 human breast cancer cell lines. Elevated expression of interleukin-8 in breast cancer cells had positive correlation with breast cancer invasion. Neutralization of antibody against interleukin-8 specifically blocked interleukin-8-mediated cell invasion. However, anti-interleukin-8 antibody did not influence the proliferation of breast cancer cells.

CONCLUSIONInterleukin-8 may be the key factor involved in human breast cancer progression and invasion, and play an important role in cell invasion of breast cancer.

OBJECTIVETo observe the effect of pBBADs-OXM-transformed bifidobacteria on the body weight of obese mice.

METHODSB. longum was transformed with pBBADs-OXM by electroporation, and arabopyranose-induced oxyntomodulin expression by the bacterium was detected by ELISA. pBBADs-OXM-transformed bifidobacteria was administered orally obese mice on a daily basis with pBBADs-GFP-transformed bifidobacteria as the negative control, and the body weight changes of the mice were observed.

RESULTSOXM was detected by ELISA not only in the supernatant but also the precipitant of the transformed bacterial culture. The body weight of the obese mice fed with pBBADs-OXM-transformed bifidobacteria decreased significantly compared with that of the mice in the obese model group (P<0.05).

CONCLUSIONAdministration of pBBADs-OXM-transformed B.longum can reduce the body weight of obese mice.

Objective To understand the obsessive-compulsive symptoms (OCS) and relative influencing factors among college students with left-behind experience. Methods College students with left-behind experience were selected from three universities in Anhui Province. The Chinese Obsessive-Compulsive Inventory-Revised (OCI-R), Rosenberg Self-Esteem Scale (RSES), Self-Rating Depression Scale (SDS) and self-edited basic situation questionnaires were used to measure the OCS, self-esteem, depression and left-behind experience. Multivariate logistic regressions model was applied to examine the influential factors of OCS. Results A total of 2 291 college students with left-behind experience were investigated. The detection rate for OCS in college students with left-behind experience were 26.5%. Regarding the OCS in college students with left-behind experience, significant differences were found in the following aspects: frequency of meeting with parents, parenting style, conflicts with caregivers, smoking and drinking (all P<0.05). Logistic regression analysis showed that caregiver adopts strict parenting style (OR=1.300, 95%CI:1.025-1.649,P=0.030), indulgent parenting style (OR=1.372, 95%CI:1.017-1.852, P=0.038), smoking (OR=1.982, 95%CI:1.305-3.011, P=0.001), depressive symptoms (OR=2.423, 95%CI:1.954-3.005, P<0.001), medium self-esteem (OR=0.604, 95%CI:0.481-0.759, P<0.001) and high self-esteem (OR=0.488, 95%CI:0.362-0.659, P<0.001) were influencing factors of OCS. Conclusions The prevalence rate of OCS among college students with left-behind experience is high. Some interventions should be taken to reduce the OCS among college students with left-behind experience.
