Objective To survey the clinical effect of combination therapy of Ninggan-Tiaozhong decoction and psychological intervention for chronic atrophic gastritis (CAG).Methods 80 cases CAG were randomly divided into a treatment group (treated with Ninggan-Tiaozhong decoction and psychological intervention) and a control group (treated with Ninggan-Tiaozhong decoction),with 40 cases in each group and performed a therapy for 12 weeks.The clinical efficacy and the change of Symptom Checklist (SCL-90)and Self-Rating Anxiety Scale(SAS) before and after treatment were evaluated.Results After 12 weeks of treatment,the total effective rate was 90.0％ in the treatment group,and 74.4％ in the control group.The treatment group was better than the control group(x2=4.255,P＜0.05).After psychological intervention,SCL-90 and SAS score (39.5±4.3,1.3± 0.6)was significantly reduced in the treatment group than the control group (51.4±3.2,1.5±0.3),(P＜0.05).Conclusion The combination therapy of Ninggan-Tiaozhong decoction and psychological intervention used in CAG is effective to relieve symptoms and to improve life quality of patients.

The interaction between the antibody and the corresponding target molecule determines the characteristics of immunoassay. In this study, a single chain variable fragment antibody (scFv4C7) derived from the hybridoma strain 4C7 were prepared via genetic engineering technique. The recognition properties of scFv4 C7 was determined and compared to those of the parent monoclonal antibody by indirect competitive enzyme-linked immunosorbent assay(ic-ELISA). Three dimensional structure of the scFv4C7 was presented by Swiss-Model, and sulfathiazole ( STZ) was docked to the scFv4C7 model to obtain the structure of the binding complex. The results from the ic-ELISA showed that the binding properties of scFv4C7 were comparable with the parent monoclonal antibody and STZ was almost completely buried in a deep binding pocket formed by the heavy chain and light chain of the antibody. The interaction between STZ and scFv4C7 was more closely related to the heavy chain and the complementarity-determining region ( CDR ) H3 loop played more important role than other CDR loops. The study preliminary provided the necessary structural information for the preparation of antibody with broader specificity and higher affinity.

Objective To evaluate the value of spectral CT imaging for the differential diagnosis of squamous cell carcinoma (SQCC) and adenocarcinoma (ADC) of the esophagogastric junction. Methods Forty-five patients with a mass in the esophagogastric junction proved by pathology underwent enhanced scan with spectral CT, including 20 cases of SQCC and 25 cases of ADC. Iodine concentration (IC) , water concentration (WC) , effective atomic number (Eff-Z) and spectral curve slope (λHU) of arterial phase (AP) and venous phase (VP) in the ROI of the mass were measured with gemstone spectral imaging post-processing software. The independent samples t test was used to compare the quantitative parameters above between two groups on the premise of satisfying normal distribution. ROC curves were drawn for the parameters which showed statistical differences and area under the curve (AUC) was used to measure and compare their respective differential diagnostic performance as well as the best threshold value. Results In AP,the average IC, Eff-Z, andλHU of ADC were (1.75±0.40) mg/ml, 8.65±0.22, and 3.33±0.74, respectively. The corresponding parameters of SQCC were (1.40 ± 0.35) mg/ml, 8.50 ± 0.20, and 2.71 ± 0.66, respectively. These parameters of ADC were significantly higher than that of SQCC (t=-2.833,-2.879,-2.678;P<0.05) . In VP, the average IC, Eff-Z, and λHU of ADC were (2.17 ± 0.23) mg/ml, 8.87 ± 0.11, and 4.10 ± 0.44, respectively. The corresponding parameters of SQCC were (1.67 ± 0.20) mg/ml, 8.60 ± 0.11, and 3.19 ± 0.41, respectively. The difference between ADC and SQCC was statistically significant (t=-6.963,-7.218,-6.521;P<0.05). For the average WC, No difference between the two groups in AP and VP was found. ROC curve analysis showed that IC, Eff-Z, andλHU in VP had better differential diagnostic performances than IC, Eff-Z, and λHU in AP, especially Eff-Z in VP. The AUC for it was 0.97. Using 8.72 as a threshold value, the sensitivity and specificity for diagnosis were 88.9% and 94.7% , respectively. Conclusion Multi-parameters quantitative analysis with spectral CT could be useful in the differential diagnosis of SQCC and ADC of the esophagogastric junction.

AIM: To compare the measurement of anterior chamber depth(ACD) inclusive of corneal thickness using intrao-cular lens(IOL) master and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method.METHODS: Two consecutive measurements of ACD were prospectively performed using IOL master and UBM in 60 eyes in 60 individuals. Mean values were compared using the paired t test. For each individual, ACD measure-ments was performed 5 times to estimate the repeatability of each method by a coefficient of variation(CV).RESULTS: The mean ACD was 2.95±0.25mm with the IOL master and 2.96±0.22mm with the UBM. This diffe-rence was not statistically significant (P=0.631).The coefficient of variation (CV) was 0.56%±0.26% and 0.65%± 0.36% in IOL master and UBM, respectively.CONCLUSION: The mean ACD of IOL master was the same as UBM. The repeatability of IOL master is better than UBM.

Objective To study the effects of light on body weight,learning and memory of mice.Methods Fifty mice aged 20 days were randomly assigned to one of the five groups: 200 W light group,100 W light group,60 W light group,40 W light group and normal control group,with 10 in each.They were exposed to different intensities of light 8 hours per day for 1 week.Then we monitored their body weight,examined the mean latency and inaccuracy number in step-down test,and examined the mean latency using a Morris' water maze to observe the effect of light pollution on the mice's learning and memory.Results Compared with the other four groups,there were significant decelerations of body weight increase in 200 W light group.No significant difference in body weight gain was found among the other four groups.The four light-treatment groups had no significant differences from control group in the mean latency,inaccuracy number in step-down test or the mean latency,or the mean crosses to the target in the Morris' water maze.Conclusion Short time high-intensity light can inhibit body weight increase in mice,but short-time light has no effect on the learning and memory of mice.

Objective To study metabolism of polyunsantured fatty acid (PUFA) and to investigate the relationship between different PUFA compositions and △6 desaturase (D6D) activity in colorectal carcinoma (CRC).Methods Fresh frozen malignant CRC tissues were obtained from 61 patients and blood samples were detected in 38 patients.The PUFA composition in these samples was determined by gas-liquid chromatography on a capillary column.The fatty acid product-to-precursor ratios in blood and tissue as estimates of desaturase activity (D6D activity index),and its relationship with the ratios between different PUFA compositions were investigated.Results Metabolism of ω-6 PUFA dominated in PUFA metabolism path.The ratio of ω-6/ω-3 PUFA was 4.89 in blood samples and 10.15 in tissues.The ratio of LA/ALA was 101.92 in blood samples and 86.16 in tissues.The ratio of ω-6/ω-3 LC-PUFA was 2.86 in blood samples and 4.51 in tissues.The D6D activity index in ω-6 PUFA metabolic processes both in tissues (t =1 1.609,P =0.00) and blood samples (t =-9.151,P =0.00) were higher than that in ω-3 PUFA.Conclusion In colorectal carcinoma,the ω-6 PUFA metabolic not only plays an important role in the metabolism of PUFA,but also is more active than the ω-3 PUFA metabolic,and in some way links to the development of tumorigenesis in CRC.

Objective To observe changes of serum concentrations of interleukin-18(IL-18) and intercellular adhesion molecule-1(ICAM-1) in neonates with hypoxic-ischemic encephalopathy(HIE) and to explore the correlation of the 2 indices and its effect on patients′condition.Methods Thirty newborn infants met the criteria for HIE.There were 16 cases in mild HIE group,14 cases in moderate and severe HIE group.Twenty normal newborn infants were used as control group.The serum concentrations of IL-18 and ICAM-1 of HIE group and control group were detected using ELISA on the third day and 7th day.Results 1.The IL-18 levels of the mild,moderate and severe HIE and control groups measured within 3 days of life were (120.1?12.7),(175.1?15.4),(100.3?12.5) ng/L,respectively.The concentrations of IL-18 in HIE groups were higher than that of control group(Pa

OBJECTIVETo study the effects of alltrans retinoic acid (ATRA) on airway responsiveness, airway remodeling and expression of matrix metalloproteinase-9 (MMP-9) protein in rats with asthma.

METHODSForty rats were randomly divided into five groups: asthma model, normal saline (control), ATRA treatment, cotton oil treatment and budesonide treatment (n=8 each). Asthma was induced by ovalbumin sensitization and challenge in the asthma model, and the ATRA, cotton oil or budesonide treatment groups. ATRA (50 μg/kg), cotton oil (1 mL) or budesonide (0.32 mg/kg) was administered before ovalbumin challenge in the three treatment groups. Airway responsiveness was assessed. The lung tissues were sampled to detect airway remodeling and the expression of MMP-9 protein by immunohistochemistry.

RESULTSThe expression of MMP-9 in lung tissues in the ATRA treatment group was significantly higher than that in the control group, but the airway responsiveness in the ATRA treatment group was not significantly different from that in the control group. The airway responsiveness and the expression of MMP-9 in lung tissues were significantly reduced in the ATRA treatment group compared with the asthma model group. The airway remodeling was significantly improved in the ATRA treatment group compared with the asthma model group.

CONCLUSIONSATRA may alleviate airway hyperresponsiveness and airway remodeling possibly through decreasing the protein expression of MMP-9 in rats with asthma.
