Objective To assess atrophy of the multifidus in elderly patients with low back pain using magnetic resonance imaging.Methods Thirty patients with low back pain were recruited,and 15 healthy subjects formed a normal group.The cross sectional area (CSA) and signal strength of the multifidus muscles at the L4-5 and L5-S1 levels were measured along with the signal strength of the hip fat for all of the subjects in both groups using a superconducting magnetic scanner.Results There was no statistically significant CSA difference between the groups at either level.The contrast between multifidus muscle and adipose tissue was significantly different between the groups at both levels.Conclusion In evaluating atrophy of the multifidus muscle in elderly patients with low back pain,the contrast between multifidus muscle and adipose tissue at either level L4-5 or L5-S1 can be used for assessment.It is more reliable,specific and sensitive than the CSA of the muscle.

Objective To observe the short term curative effect,life quality,adverse reactions of Jianpibufei decoction combined with chemotherapy in the treatment of patients with advanced non small cell lung cenacer.Methods 60 patients with advanced non small cell lung cenacer were randomly divided into the treatment group and the control gnoup,each group 30 cases.The treatment group was treated with TP scheme and Jianpibufei decoction.The contwl group was only treated with TP scheme.The effect,life quality and the injury of liver and kidney function was observed and compared between the two groups.Results The difference of the remission rate between the two groups had no statistical significance(x2 =0.418,P ＞ 0.05).The improving rate of life quality in the treatment group was 70％,and higher than that in the control group(40％)(x2 =6.545,P ＜0.05).The reduction of the white blood cell,the hemoglobin,platelet and the injury of liver function in the treatment group were lower than those in the control group obviously(Z=-2.516,-2.184,-2.059,-2.097,all P＜0.05).Conclusion Jianpibufei decoction combined with chemotherapy in the treatment of patients with advanced non small cell long cenacer could not increase the effect,but could reduce the adverse reaction of the chemotherapy and improve the life quality of patients.

ObjectiveTo investigate the effects of treadmill testing guided-rehabilitation exercises upon quality of life (QOL) of patients who underwent revascularization for coronary heart disease (CHD).Methods All the participants received routine therapy and rehabilitation for 6 weeks.A 36-item short-form (SF-36) was used to assess QOL of the patients.Results Injured functioning of patients who received revascularization for CHD were physiological function ( 37.86 ),social function ( 43.67 ),vitality (45.58),physical performance ( 65.45 ),mental health ( 68.73 ),role emotion ( 71.30 ),physical pain ( 79.52 ),and general health ( 86.75 ).After intervention,physiology function ( 37.86 ± 8.49 vs 62.13 ± 10.53 ),social function (43.67 ±26.23 vs 56.98 ± 18.89),vitality (45.58 ±27.01 vs 77.42 ±23.48),and physical pain (79.52 ±9.05 vs 87.32 ± 13.14) were significantly improved.Conclusion Rehabilitation exercises and behavioral psychological treatment may be beneficial to improve QOL of patients undergoing revascularization for CHD.

Objective To determine the relationship of the expression of aquaporin 5 (AQP5)with clinicopathology and prognosis of colorectal cancer.Methods We collected data from 45 patients with primary colorectal cancer without any adjuvant therapy before operation.The expression of AQP5 was measured by immunohistochemistry (IHC).Then we analyzed the correlation between AQP5 expression and clinicopathological parameters (including age,tumor size,clinical staging,tumor location,lymph node and pathological type)and the connection between AQP5 expression and prognosis based on follow-up data.Results Of the 45 tumor specimens,14 (31.1%)had a high level of AQP5 expression,29 (64.4%)exhibited a moderate level of staining,and 2 (4.4%)had an absence of AQP5 staining.AQP5 was only occasionally detected in para-neoplastic [3/45 (6.67%)]and normal tissues [3/45 (6.67%)].The overexpression of AQP5 was also positively associated with TNM stage (P =0.002),lymph node metastasis (P =0.01 6),and distant metastasis (P =0.000).However,it had no significant association with age, gender,histologic grade or tumor size (P > 0.05 ).Conclusion AQP5 may be used as a novel biomarker for predicting the prognosis of colorectal cancer.

Objective To evaluate the effect of modified bowel preparation-Polyethylene Glycol Electrolytes Powder (SF-PEG, Shu Taiqing) in combination with magnesium sulfate in patients with constipation undergoing colonoscopy. Methods Sixty cases from mild to moderate constipation were randomly divided into two groups:Group A: SF-PEG (438.4 g, 4 L), 30 cases; Group B: received low-dose SF-PEG (219.2 g, 2 L) and 50.00%magnesium sulfate 50 ml, and then 250 ml water, 30 cases. Boston Bowel Preparation Scale scores (BBPS) and bubbles in bowel lumen score were assessed by the same endoscopist blindly to the preparation regimen, and the time of colonoscopy and the tolerability was recorded. Results All patients underwent completely the bowel preparation and colonoscopy. The time of colonoscopy of group B was shorter than that of group A (P < 0.05). The BBPS score of group B was higher than that of group A (P < 0.05). The bubbles in bowel lumen were less in Group B than in Group A (P < 0.05). The willingness to retake in Group B were superior to those in Group A (P < 0.05). No significant difference was found in score of total adverse effects and taste score between the two groups (P > 0.05). Conclusion SF-PEG in combination with magnesium sulfate in patients with constipation for colonoscopy can improve tolerance to bowel preparation, cleanliness and effects of examination. It's safe to be recommended in clinical practice.

Background/Aims: Lipopolysaccharide (LPS) is the key factor inducing mucosal and systemic inflammation in various intestinal and parenteral diseases, which could initially disrupt the epithelial barrier function. EphrinA1/ephA2 is speculated to increase the epithelial permeability for its “repulsive interaction” between adjacent cells. This study aim to investigate the role of ephrinA1/ephA2 in LPS-induced epithelial hyperpermeability. Methods: In vivo model challenged with oral LPS in C57BL/6 mice and in vitro model exposed to LPS in Caco2 monolayer were established. The barrier function was assessed including expression of tight junction proteins (occludin and claudin-1), transepithelial electrical resistance, and permeability to macromolecules (fluorescein isothiocyanate-labeled fluorescent dextran 4 kDa [FD4]). Moreover, the expression and phosphorylation of ephrinA1/ephA2 were quantified, and its roles in the process of epithelial barrier disruption were confirmed via stimulating ephA2 with ephrinA1-Fc chimera (ephrinA1-Fc) and inactivating ephA2 with ephA2-Fc chimera (ephA2-Fc), or ephA2 monoclonal antibody (ephA2-mab), as well as inhibiting extracellular signal-regulated kinase 1/2 (ERK1/2) with PD98059. Results: LPS induced significant barrier dysfunction with dismissed occludin and claudin-1 expression, reduced transepithelial electrical resistance and increased FD4 permeability, accompanied by upregulated ephrinA1/ephA2 pathway and phosphorylation of ephA2 receptor. Furthermore, ephA2-Fc, and ephA2-mab ameliorated LPS-induced epithelial hyperpermeability, which was also inhibited by PD98059. Additionally, ephrinA1-Fc led to apparent epithelial leakage in Caco2 monolayer by promoting the phosphorylation of ERK1/2, which could be obviously blocked by ephA2-mab and PD98059. Conclusion EphrinA1/ephA2 promotes epithelial hyperpermeability with an ERK1/2-dependent pathway, which involves in LPS-induced intestinal barrier dysfunction.

Objective To analyze the epidemiological surveillance results of human brucellosis in Shanxi Province from 2012 to 2017,to know the epidemic status of brucellosis,and to provide evidence for prevention and control of brucellosis.Methods Incidence date and surveillance date of disease outbreaks in Shanxi Province from 2012 to 2017 were collected,the retrospective analysis method was used to analysis the "three distribution" of brucellosis,outbreak situation and the results of serological and pathogenic surveillance in the 4 surveillance stations.Results A total of 36 220 brucellosis cases were reported from 2012 to 2017,the average incidence was 16.62/100 000;8 540 brucellosis cases were reported in 2014,with incidence 23.53/100 000;a total of 23 197 cases of brucellosis were reported mainly in Datong,Shuozhou,Jinzhong and Xinzhou,accounting for 64.04％ of the province total.The onset was seasonal,and the peak of the epidemic was from March to August,accounting for 67.23％ (24 350/36 220).The brucellosis cases were mainly youth (23 084),male (28 317),farmers and herdsman (32 616).In the 4 surveillance stations of the brucellosis,39 140 cases were investigated,of which 10 536 cases did serological test,in which 585 were positive for Brucella (5.55％).The highest positive rate of serological test was 9.50％ (226/2 738) which was found in Tianzhen.A total of 626 samples carried out pathogen culture,in which 107 strains of brucellosis were detected,the detection rate was 17.09％,and 106 strains Brucella were melitensis biovar 3 of the total strains except 1 mutant.Conclusions The reported incidence in Shanxi Province is in a decline tendency,but the situation of brucellosis epidemic is still relatively serious.It is suggested that the surveillance work should be strengthened;the epidemic situation of brucellosis should be mastered in time and effectively controlled.

Cryptosporidium is an important intestinal parasite that is mainly transmitted through the fecal-oral route. Human infection may occur following ingestion of water and food contaminated by Cryptosporidium oocysts, and children and immunocompromised individuals are at a high risk of infections. The main symptoms of Cryptosporidium infections include diarrhea, vomiting, malnutrition, and even death. Because of high sensitivity and rapid procedures, molecular tests are helpful for the diagnosis of cryptosporidiosis and may reduce the public health risk of cryptosporidiosis. This review summarizes the advances in the latest prevalence and molecular detection of human Cryptosporidium infections during recent years.
