Objective To identify etiological factors for non-ulcer dyspepsia (NUD) in elderly patients presenting to the emergency department.Methods A total of 97 elderly patients with NUD presenting to the emergency department from January 2011 to December 2013 were enrolled in the NUD group and 116 elderly people undergoing annual physical examinations served as the control group.Clinical data,including Helicobacter pylori (HP) infection,unhealthy living habits,anxiety,depression and regular intake,were collected and compared between the two groups.Results Compared with the control group,the NUP group showed a higher HP infection rate [70.1％ (68/97)vs.54.3％ (63/116),x2 =5.565,P＜0.05],a higher incidence of unhealthy living habits (unhealthy dietary habits,smoking,drinking,and lack of regular exercise) (P＜0.05),a higher incidence of suspect anxiety/anxiety and a higher incidence of regular intake [30.9％ (30/97) vs 10.3％ (12/116),x2=14.138,P＜0.05].SerumpepsinogenⅠ(PGⅠ) [(178.7±13.6) μg/L vs.(125.2±10.5)μg/L,t=1.971,P＜0.01] and serum pepsinogen Ⅱ(PG Ⅱ) [(28.8±5.3) μg/L vs.(14.7±3.8)μg/L,t=1.960,P＜0.01] levels were also higher in the elderly NUD patients than in the control group.Conclusions HP infection,unhealthy living habits,anxiety and/or depression,and regular intake are closely associated with NUD in the elderly.Serum PGⅠ and PGⅡ could be used as markers in screening for malignant lesions in elderly patients with dyspepsia.

The nutritional survey was made in 184 anorexia children aged 3-7, 123 of them were treated with various measures for three months. The results indicated that the children with anorexia had low intake and deficiency in energy, protein, minerals and vitamins. Most of them had zinc deficiency, but they simultaneously had two to three nutrients deficiency.The zinc treatment could improve most patient's syndrome and nutritional status. The effect of zinc treatment with vitamines and iron preparations was better than zinc treatment only. The effect of treatment with Chinese medicine also was able to cure the children with anorexia to certain extent.

Results The probationers and rotating physicians had significant improvement in the familiarity and mastery of ICU specialist knowledge and skills through the systematic training. Conclusion Such training program can effectively improve the ICU specialized quality and comprehensive ability of the probationers and rotating physicians and bring about better clinical teaching effect.

Objective To analyze the levels of T helper(Th)17-related cytokines interleukin(IL)-17,IL-22,IL-23 and IL-27 in plasma of patients with systemic lupus erythematosus(SLE).Methods Plasma IL-17,IL-22,IL-23 and IL-27 levels were measured by enzyme-linked immunosorbent assay in 45SLE patients and 32 healthy controls and their associations with each other,disease activity and clinical features were evaluated.Results Plasma levels of IL-17 and IL-23 were significantly higher in SLE patients than in controls[77.8(25.4～487.6)pg/ml vs 36.4(15.7～338.2)pg/ml;14.7(<7.8～247.5) pg/ml vs <7.8(<7.8～81.7)pg/ml.both P<0.01].with no difference between active and inactive disease.In contrast,IL-22 levels were markedly decreased in SLE patients compared with the controls[77.4(<15.6～559.7)pg/ml vs 378.8(21.8～1154.2)pg/ml,P<0.01]and were lower in active disease than in inactive disease(P<0.01).IL-27 levels tended to be higher in SLE patients compared with controls,but the difference was not significant (P>0.05).A strong and positive correlation was found between IL-17 and IL-23 levels(P<0.01)in SLE patients.IL-22 levels were negatively correlated with SLEDAI score,erythrocyte sedimentation rate and antidsDNA antibody titers(all P<0.01),and positively correlated with C3 levels (P<0.05).Each cytokine levels were not related to specific manifestations and treatments.Conclusion Th17 cytokine response in peripheral blood of patients with SLE is abnormal.and IL-17 and IL-22 appear to play different roles in SLE pathophysiology.IL-23/IL-27 imbalance may contribute to the development of Th17-mediated inflammation in SLE.

ObjecfiveTo compare the sensitivity of diffusion weighted imaging(DWI)with dynamic contrast enhanced(DeE)MRI for the detection of small breast caJlcers and to evaluate the clinical value of DWI.MethodsForty-eight patients with benign(n=25)and malignant(n=45)small breast lesions(≤2 cm)proved by pathology underwent DWI and DCE MRI.The DCE MRI was performed using FLASH sequence and the time-signal intensity chive was drawn.The DWl was performed using GRAPPAEPI sequence with different b values(800,1000 s/mm2) and the ADC values of lesions were measured.The sensitivity and specificity of DWI for the detection of small breast cancers were compared with DCE MRI. ResultsForty of 45 small breast cancers and 19 of 25 small benign breast lesions were corrlectly diagnosed using DCE MRI.The sensitivity and positive predictive value of TIC were 88.9%(40/45)and 87.0%(40/46).With b values of 800 s/mm2 and 1000 s/mm2,the avemge ADC values of small breast cancers were(1.153±0.192)× 10-3 and(1.079±0.186)× 10-3 mm2/s,while those of benign ones were (1.473±0.252)×10-3 and(1.419±0.255)×10-3 mm2/s,respeetively. There was no significant difference for the ADC values with different b values in the same group(P＞0.05),while there was a signiticant difference between the malignant and the benign lesions(P＜0.05)Thirty-nine of 45 small breast cancers and 19 of 25 small benign breast lesions were correctly diagnosed using DWI with b value of 1000see/mm2.Both the sensitivity and positive predictive value of diagnosis were 86.7%(39/45).The abilities of DWI and DCE MRI for the diagnosis of small breast cancers werle the same. The sensitivity(93.3%)and positive predictive value(91.3%)were improved with the combination of DCE MRI and DWI. Conclusion DWI has a high sensitivity for the detection of small breast cancers,the ADC value can provide valuable information in the differential diagnosis.

A predominant chrysene-degrading strain was isolated and screened from biological sludge sampled from a coking plant,which can use chrysene as sole carbon source for growth in the selective culture me-dium.The phylogenetic tree of the strain was produced on the basis of morphology observation by SEM,experimental results of physiology and biochemistry and analysis of 16S rDNA sequence.The strain was identified as Achromobacter xylosoxidans.The effect of initial concentration of chrysene solution,inoculat-ing dose and pH on degradation efficiencies was investigated.The results indicate that the degrading charac-teristics of the strain is fine.The optimal degrading conditions are:initial concentration of chrysene solution 40 mg/L,inoculating dose(V/V)10%,pH 7.0~7.5,respectively.Under the optimal conditions,the degrading efficiency can reach more than 80% after 5 days at 30?C.

Submerged fermentation parameters for the chromium-rich mycel ia of Coprinus comatus was studied in optimal medium. According to the yield of organic Cr, the optimal fermentation parameters were obtained as follows: the amount of CrCl_3 6H_2O in medium was 200mg/L; the inoculation volume was 8%~10%; the aeration ratio was 80:250 (medium volume: flask volume); the cul tural period was 5 days at 26℃ and at 100r/min. The highest yield of organic C r in mycelia of Coprinus comatus was 1597.88?g/100mL and the enrichment ra te of Cr was about 9.09%.

Objective Irregular antibody screening and identification are very important to reduce hemolytic reaction.The dis-tribution of irregular antibodies of blood group was analyzed in patients, to provide evidence for using Micro column gel test to detect and identify irregular antibodies transfusion safety. Methods Micro column gel anti-globulin technique was used to screen the irregular an-tibodies and cross-matching in 29770 patients.If the serum had irregular antibodies, the spectrum cells were used to identify the specific-ity of irregular antibodies. Results Among 29 770 patients, 120 cases had irregular antibodies of blood group.The positive rate was 0.4%.The irregular antibodies include Rh system(n=67),MNS system (n=7), Lewis system(n=5),cases of Kidd system(n=3) and undefined specified antibodies(n=38).Among the 120 antibody-positive patients, 70 were female patients and 50 were male patients. Further study showed that the pregnancy history was to the main factor causing irregular antibodies in women (46 positive cases among 70 female patients) . Conclusion The study showed that some patients had irregular antibodies of blood group, especially female patients with pregnancy history.These results suggested that irregular antibody screening and cross-matching by micro column gel method in pa-tients before transfusion had great significance for ensuring the blood transfusion safety.

OBJECTIVETo study the regulatory effect of Huoxiang Zhengqi Extract (HZE) on the intestinal mobility in rat model of diarrhea-predominant irritable bowel syndrome (D-IBS).

METHODSEighty experimental rats were randomly divided into two parts, forty in each. Rats in one part were used in the carbon powder experiment, while the rest rats were used in the gastrointestinal transit test. Rats in each part were divided into five groups, i.e., the blank control group, the model group, and the high, moderate, and low HZE treated groups, eight in each. Normal rats consisted of the blank control group. Except for the blank control group, D-IBS model was established by gastrogavage of senna at the dose of 0.2 g/mL at 25 degrees C with 2-h restraint stress of extremities for six successive days. After modeling, high (804 mg/kg), moderate (536 mg/kg), and low (268 mg/kg) dose HZE was respectively administered to rats of the three corresponding groups. Effect of HZE on the small intestine propulsion rate and serum levels of nitric oxide (NO), 5-hydroxytryptamine (5-HT) as well as chromaffin cells in colonic epithelium (EC) were detected by carbon powder experiment, gastrointestinal transit test, nitrate reductase method, ELISA, and immunohistochemistry, respectively.

RESULTSCompared with the model group, HZE could lower the small intestine propulsion rate of D-IBS model rats, attenuate the colon transition, improve serum NO level, lower 5-HT level, and lessen the amount of EC.

CONCLUSIONHZE showed regulatory effect on the intestinal function of D-IBS rats.
